46 2008-12-11 Akim Demaille <demaille@gostai.com>
49 * tests/local.mk: Replace "cd && testsuite" by "testsuite -C".
50 Solves problems when top_srcdir is an absolute path.
51 Suggested by Eric Blake.

63 Fix portability issue in the test suite.
64 * tests/local.at (AT_MATCHES_CHECK): New.
65 Based on Perl instead of Sed. Sed has too many portability
66 pitfalls, not ever Sed is GNU Sed.

98 Makefile properly updates atconfig when needed.
100 2008-12-07 Di-an Jan <dianj@freeshell.org>
102 Implement the FIXME that ends an user action with a semicolon
103 if it seems necessary.
104 * src/scan-code.l (flex rules section): Flag cpp directive from
105 any `#' to the first unescaped end-of-line. Semicolon is not
106 needed after `;', `{', '}', or cpp directives and is needed after
107 any other token (whitespaces and comments have no effect).

140 Use b4_symbol for printers and destructors everywhere.
141 * data/bison.m4 (b4_symbol_action_location): New.
142 * data/c.m4 (b4_symbol_actions): Remove.
143 Adjust all callers to use by b4_symbol_foreach and the corresponding
144 b4_symbol_printer/destructor macro.
145 * data/glr.cc: Adjust.
146 * data/lalr1.java: Adjust the %destructor sanity check.
147 * src/output.c (symbol_code_props_output): Remove, we no longer
148 need the b4_symbol_printers/destructors tables.
150 2008-12-01 Akim Demaille <demaille@gostai.com>
153 * data/lalr1.cc, data/bison.m4 (b4_symbol_action): Use

162 (b4_type_foreach): Move to...
163 * data/bison.m4: Here.
164 * data/lalr1.cc (b4_symbol_action): Specialize for C++: use
165 b4_symbol_value_template instead of b4_symbol_value.
167 2008-12-01 Akim Demaille <demaille@gostai.com>
169 b4_symbol/type_foreach.
170 * data/lalr1.cc (b4_symbol_foreach, b4_type_foreach): New.
173 2008-12-01 Akim Demaille <demaille@gostai.com>
175 Use the symbol properties to output the printer/destructor for lalr1.cc.
176 Instead of defining complex list of tuples to define various
177 properties of the symbols, we now prefer to define symbols as
178 "structs" in m4: using the symbol key (its number), and the
179 property name, b4_symbol gives it value. Use this to handle
180 destructors and printers.
182 * src/output.c (CODE_PROP): New.
183 (prepare_symbol_definitions): Use it to define the printer and
184 destructor related attributes of the symbols.
185 * data/lalr1.cc (b4_symbol_actions): Rename as...
186 (b4_symbol_action): this.
187 Use b4_symbol instead of 6 arguments.

195 v__ and p__ instead of v and p.
197 2008-12-01 Akim Demaille <demaille@gostai.com>
199 Remove spurious empty line before syncline.
200 * data/bison.m4 (b4_syncline): Don't output an empty line before
203 2008-11-26 Akim Demaille <demaille@gostai.com>
205 Convert lib/Makefile.am into lib/local.mk.
206 The real problem is rather gnulib.mk, which itself is extracted
207 from a Makefile.am that gnulib expects to the "recursive". The
208 tool prefix-gnulib-mk converts such a gnulib.mk to be
209 non-recursive. Also, some AC_SUBST variables need to be adjusted.
211 * etc/prefix-gnulib-mk: New.
212 * bootstrap (slurp): Use it to convert further gnulib.mk.
213 No longer try to avoid re-creation of lib/gnulib.mk as the changes
215 * lib/Makefile.am: Rename as...
216 * lib/local.mk: this.
217 Adjust to be prefixed.
218 * Makefile.am, configure.ac: Adjust.
219 * src/local.mk (AM_CPPFLAGS): Extend it, don't define it.

230 Use b4_parser_tables_define in glr.cc.
231 * data/glr.c: Use b4_parser_tables_define instead of defining the
232 (deterministic integral) tables by hand.
234 2008-11-26 Akim Demaille <demaille@gostai.com>
236 Use b4_parser_tables_define in Java.
237 * data/java.m4 (b4_typed_parser_table): Rename as...
238 (b4_typed_parser_table_define): this, for consistency.
239 Accept a comment as $4.
241 (b4_integral_parser_table): Rename as...
242 (b4_integral_parser_table_define): this.
243 * data/lalr1.java: Adjust all uses.

256 (b4_table_define, b4_table_declare): Rename as...
257 (b4_integral_parser_table_define)
258 (b4_integral_parser_table_declare): these.
259 (yyrline_): Move the comment where it is actually used.
260 * data/yacc.c: Adjust.
261 (yyrline): Use b4_integral_parser_table_define.
263 2008-11-26 Akim Demaille <demaille@gostai.com>
266 * src/parse-gram.h, src/parse-gram.c: Regen.
268 2008-11-26 Akim Demaille <demaille@gostai.com>
270 Factor the generation of the (integral) tables bw yacc.c and lalr1.cc.

275 * data/lalr1.cc: Use them.
276 * data/c.m4 (b4_table_define): New.
277 * data/yacc.c: Use b4_tables_define instead of output the tables
279 * tests/regression.at (Web2c Actions): Adjust the expected output,
280 the order of the tables changed.
282 2008-11-26 Akim Demaille <demaille@gostai.com>
284 Get rid of (yy)rhs and (yy)prhs.
285 These tables are no longer needed in the parsers, and they don't seem to
286 be useful. They are not documented either.
288 * src/output.c (prepare_rules): Get rid of rhs and prhs.
289 Adjust the computation of (yy)r2.
291 2008-11-26 Akim Demaille <demaille@gostai.com>
293 Rule length is unsigned.
294 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
296 2008-11-26 Akim Demaille <demaille@gostai.com>
298 Get rid of lalr1-split.cc.
299 It was no longer maintainer.
301 * data/lalr1-split.cc: Remove.
302 * etc/bench.pl.in (bench_fusion_parser): Remove.
305 2008-11-26 Akim Demaille <demaille@gostai.com>
307 Use yy* consistently.
308 * data/glr.c: Now that yyrhs no longer exists as a global
309 variable, rename local "rhs" variables into "yyrhs" for

314 Get rid of yyrhs and yyprhs in glr.c.
315 * data/glr.c (yyrhs, yyprhs): Remove.
316 Instead, use the state stack and yystos.

321 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
322 as an Autotest keyword.
324 2008-11-25 Akim Demaille <demaille@gostai.com>
326 Prefer TESTSUITE_FLAGS.
327 TESTSUITEFLAGS is barely readable.
329 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
330 for backward compatibility.
331 Use the former instead of the latter.
333 2008-11-25 Akim Demaille <demaille@gostai.com>
335 Get rid of yyrhs and yyprhs in larl1.java.
336 * data/lalr1.java (yyrhs_, yyprhs_): Remove.
337 (yy_reduce_print): Rather, use yystos_ and the state stack.
339 2008-11-25 Akim Demaille <demaille@gostai.com>
343 2008-11-25 Akim Demaille <demaille@gostai.com>
345 Get rid of yyrhs and yyprhs in yacc.c.
346 They were used to get the symbol types, given a rule number, when
347 displaying the top of the stack before a reduction. But the
348 symbol type is available from the state stack. This has two be
349 benefits: two tables less in the parser (making it smaller), and a
350 more consistent use of the three stacks which will help to fuse
353 * data/yacc.c (yyprhs, yyrhs): Remove.
354 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
355 (yy_reduce_print): Take yyssp as argument.
356 Use it, together with yystos, to get the symbol type.
357 * tests/regression.at (Web2c Report): Remove these tables from the
360 2008-11-25 Akim Demaille <demaille@gostai.com>
363 The point is to factor the generation of the tables across skeletons.
364 This is language dependant.
366 * data/c.m4 (b4_comment_): New.
367 Should be usable to define how to generate tables independently of
370 (b4_comment): Bounce to b4_c_comment.
371 Now support $2 = [PREFIX] for indentation.
372 * data/lalr1.cc (b4_table_declare): Don't output a comment if
374 Indent it properly when there is one.
375 Output the ending semicolon.
376 (b4_table_define): Space changes.
377 Output the ending semicolon.
378 (b4_tables_map): New.
379 Use it twice instead of declaring and defining the (integral)
382 2008-11-25 Akim Demaille <demaille@gostai.com>
385 * data/lalr1.cc (b4_table_declare): New.

542 * src/parse-gram.h, src/parse-gram.c: Regen.
544 2008-11-15 Akim Demaille <demaille@gostai.com>
546 Support parametric types.
548 There are two issues to handle: first scanning nested angle
549 bracket pairs to support types such as std::pair< std::string,
550 std::list<std::string> > >.
552 Another issue is to address idiosyncracies of C++: do not glue two
553 closing angle brackets together (otherwise it's operator>>), and
554 avoid sticking blindly a TYPE to the opening <, as it can result
555 in '<:' which is a digraph for '['.
557 * src/scan-gram.l (brace_level): Rename as...
560 Implement support for complex tags.
563 * data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)
564 (b4_symbol_variant): Leave space around types as parameters.
565 * examples/variant.yy: Use nested template types and leading ::.
566 * src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):
568 (TAG, TAG_ANY, TAG_NONE, tag.opt): these.
569 * tests/c++.at: Test parametric types.
571 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
574 This is not sufficient, but we test at least that the make_SYMBOL
575 interface is not affected by token.prefix. A more general test
576 will be implemented when the support of token.prefix is generalized
579 * tests/c++.at: One more variant test, using token.prefix.
581 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
583 Test the make_TOKEN interface.
584 * tests/c++.at (AT_CHECK_VARIANTS): Require and use locations.
585 Factor the common code in yylex.
586 Use it to test "%define lex_symbol".

592 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
594 Simplify code for variants bench marks.
595 * etc/bench.pl.in (&generate_grammar_list): Define and use
597 Factor the common code in yylex.
599 2008-11-15 Akim Demaille <demaille@gostai.com>
601 Better error message.
602 * bootstrap (find_tool): Fix the error message.
604 2008-11-15 Akim Demaille <demaille@gostai.com>
606 Update variant.yy to newest interface.
607 * examples/variant.yy: Define lex_symbol.
610 2008-11-15 Akim Demaille <demaille@gostai.com>
612 Don't use locations in variant.yy.
613 * examples/variant.yy: Adjust to not using locations.
615 2008-11-15 Akim Demaille <demaille@gostai.com>
618 * data/local.mk, etc/local.mk, examples/local.mk: Use Automake
619 comments for the license.
621 2008-11-15 Akim Demaille <demaille@gostai.com>
623 Remove tests/Makefile.am.
624 * tests/Makefile.am: Rename as...
625 * tests/local.mk: this.
626 * Makefile.am, configure.ac: Adjust.
627 * Makefile.am (DISTCLEANFILES): Define.
628 (maintainer-check, maintainer-xml-check, maintainer-push-check):
629 Remove, we no longer need to bounce to the real targets.
631 2008-11-15 Akim Demaille <demaille@gostai.com>
635 2008-11-15 Akim Demaille <demaille@gostai.com>
638 * Makefile.am (EXTRA_DIST): Move djgpp related part to...
639 * djgpp/local.mk: this new file.
641 2008-11-15 Akim Demaille <demaille@gostai.com>
643 Remove doc/Makefile.am.
644 * doc/Makefile.am: Rename as...
645 * doc/local.mk: this.
647 * Makefile.am, configure.ac: Adjust.
648 * Makefile.am (MOSTLYCLEANFILES): New.
649 * src/local.mk: Adjust.
651 2008-11-15 Akim Demaille <demaille@gostai.com>
653 Move sc_tight_scope into maint.mk.
654 It does not work, and I don't know how it was supposed to work: it
655 seems to be looking for sources in the build tree. I just moved
656 it at a better place, fixing it is still required.
658 * src/local.mk (echo): Remove.
659 (sc_tight_scope): Move to...
662 2008-11-15 Akim Demaille <demaille@gostai.com>
665 * src/parse-gram.h, src/parse-gram.h: Regen.
667 2008-11-15 Akim Demaille <demaille@gostai.com>
669 Remove src/Makefile.am.
670 * src/Makefile.am: Rename as...
671 * src/local.mk: this.
672 Prefix all the paths with src/.
673 (AUTOMAKE_OPTIONS): Build object files in the sub dirs.
674 (AM_CPPFLAGS): Find find in builddir/src.
675 (YACC): Move the flags into...
677 * maint.mk (sc_tight_scope): Disable.
678 It used to bounce to the version in src/Makefile.am which is now
679 part of this very Makefile.
680 * Makefile.am, configure.ac: Adjust.
681 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
682 include "..." to find files "here": we are no longer in src/, so
683 qualify the includes with src/.
684 * doc/Makefile.am (PREPATH): No longer include the top_builddir
686 (.x.1): Adjust to be able to create src/foo from the top level
687 Makefile, instead of going bounce to src/Makefile the creation of
690 2008-11-15 Akim Demaille <demaille@gostai.com>
692 Remove useless variable.
693 * doc/Makefile.am (srcsrcdir): Remove.

697 Remove data/Makefile.am.
698 * data/Makefile.am: Rename as...
699 * data/local.mk: this.
701 * Makefile.am, configure.ac: Adjust.
703 2008-11-15 Akim Demaille <demaille@gostai.com>
705 Remove etc/Makefile.am.
706 * etc/Makefile.am: Rename as...
707 * etc/local.mk: this.
709 * Makefile.am, configure.ac: Adjust.
711 2008-11-15 Akim Demaille <demaille@gostai.com>
713 Remove examples/local.mk.
714 examples/calc++/Makefile.am might be interesting to keep as is, since
715 it is an example in itself.
717 * examples/Makefile.am: Rename as...
718 * examples/local.mk: this.
720 * Makefile.am, configure.ac: Adjust.
722 2008-11-15 Akim Demaille <demaille@gostai.com>
724 Remove build-aux/Makefile.am.
725 Recursive Makefiles are really way too slow, let's get rid of some of
728 * build-aux/Makefile.am: Rename as...
729 * build-aux/local.mk: this.
731 * Makefile.am, configure.ac: Adjust.
733 2008-11-15 Akim Demaille <demaille@gostai.com>
735 Provide convenience constructors for locations and positions.
736 * data/location.cc (position::position): Accept file, line and
737 column as arguments with default values.
738 Always qualify initial line and column literals as unsigned.
739 (location::location): Provide convenience constructors.
741 2008-11-15 Akim Demaille <demaille@gostai.com>
743 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
745 Using template buys us nothing, and makes it uselessly complex to
746 construct a symbol. Besides, it could not be generalized to other
747 languages, while make_FOO would work in C/Java etc.
749 * data/lalr1.cc (b4_symbol_): New.
751 (b4_symbol_constructor_declaration_)
752 (b4_symbol_constructor_definition_): Instead of generating
753 specializations of an overloaded template function, just generate
754 several functions whose names are forged from the token names
755 without the token.prefix.
756 (b4_symbol_constructor_declarations): Generate them for all the
757 symbols, not just by class of symbol type, now that instead of
758 specializing a function template by the token, we generate a
759 function named after the token.
760 (b4_symbol_constructor_specialization_)
761 (b4_symbol_constructor_specializations): Remove.
762 * etc/bench.pl.in: Adjust to this new API.
764 2008-11-13 Akim Demaille <demaille@gostai.com>
766 %define token.prefix.
767 Provide a means to add a prefix to the name of the tokens as
768 output in the generated files. Because of name clashes, it is
769 good to have such a prefix such as TOK_ that protects from names
770 such as EOF, FILE etc. But it clutters the grammar itself.
772 * data/bison.m4 (token.prefix): Empty by default.
773 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
774 * data/lalr1.cc (b4_symbol): Ditto.
776 2008-11-13 Akim Demaille <demaille@gostai.com>
778 Compute at M4 time some of the subtractions.
779 * data/lalr1.cc (b4_subtract): New.
780 (b4_rhs_data): Use it.
782 2008-11-13 Akim Demaille <demaille@gostai.com>
785 This allows the user to get the type of a token returned by yylex.
787 * data/lalr1.cc (symbol::token): New.
788 (yytoknum_): Define when %define lex_symbol, independently of
790 (yytoken_number_): Move into...
791 (symbol::token): here, since that's the only use.
792 The other one is YYPRINT which was not officially supported
793 by lalr1.cc, and anyway it did not work since YYPRINT uses this
794 array under a different name (yytoknum).
796 2008-11-13 Akim Demaille <demaille@gostai.com>
799 * TODO (YYERRCODE): Mention the case of $undef.
801 2008-11-13 Akim Demaille <demaille@gostai.com>
804 * TODO (YYPRINT): New.
806 2008-11-13 Akim Demaille <demaille@gostai.com>
809 * data/lalr1.cc, data/yacc.c: Fix the description of the
810 yytranslate and yytoknum tables.
812 2008-11-13 Akim Demaille <demaille@gostai.com>
814 Define make_symbol in the header.
815 To reach good performances these functions should be inlined (yet
816 this is to measure precisely). To this end they must be available
819 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
820 location_type with the class name.
821 Since will now be output in the header, declare "inline".
822 No longer use b4_symbol_constructor_specializations, but
823 b4_symbol_constructor_definitions in the header.
824 Don't call it in the *.cc file.
826 2008-11-13 Akim Demaille <demaille@gostai.com>
828 Define yytranslate in the header for lex_symbol.
829 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
830 into the header file when using %define lex_symbol.
831 (yytranslate_): Declare inline.
833 2008-11-13 Akim Demaille <demaille@gostai.com>
835 Define the constructors of symbol_type in
836 b4_symbol_constructor_definitions.
837 The constructors are called by the make_symbol functions, which a
838 forthcoming patch will move elsewhere. Hence the interest of
839 putting them together.
841 The stack_symbol_type does not need to be moved, it is used only
844 * data/lalr1.cc: Move symbol_type and symbol_base_type
846 (b4_symbol_constructor_definitions): here.
849 2008-11-13 Akim Demaille <demaille@gostai.com>
851 Make it easier to move the definition of yytranslate_.
852 Forthcoming changes will make it possible to use yytranslate_
853 from outside the parser implementation file.
855 * data/lalr1.cc (b4_yytranslate_definition): New.
858 2008-11-13 Akim Demaille <demaille@gostai.com>
860 Remove useless class specification.
861 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
862 to refer to the class name to use a type defined by the class for
863 arguments of member functions.
865 2008-11-13 Akim Demaille <demaille@gostai.com>
867 Finer input type for yytranslate.
868 This patch is debatable: the tradition expects yylex to return an int
869 which happens to correspond to token_number (which is an enum). This
870 allows for instance to return characters (such as '*' etc.). But this
871 goes against the stronger typing I am trying to have with the new
872 lex interface which return a symbol_type. So in this case, feed
873 yytranslate_ with a token_type.
875 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
878 2008-11-13 Akim Demaille <demaille@gostai.com>
880 Honor lex-params in %define lex_symbol mode.
881 * data/lalr1.cc: Use b4_lex_param.
883 2008-11-13 Akim Demaille <demaille@gostai.com>
886 * src/output.c (symbol_definitions_output): Rename symbol
887 attributes type_name and has_type_name as type and has_type.
888 * data/lalr1.cc: Adjust uses.
890 2008-11-13 Akim Demaille <demaille@gostai.com>
892 Use b4_type_names for the union type.
893 The union used to compute the size of the variant used to iterate
894 over the type of all the symbols, with a lot of redundancy. Now
895 iterate over the lists of symbols having the same type-name.
897 * data/lalr1.cc (b4_char_sizeof_): New.
898 (b4_char_sizeof): Use it.
899 Adjust to be called with a list of numbers instead of a single
901 Adjust its caller for new-line issues.
903 2008-11-13 Akim Demaille <demaille@gostai.com>
905 Define the "identifier" of a symbol.
906 Symbols may have several string representations, for instance if
907 they have an alias. What I call its "id" is a string that can be
908 used as an identifier. May not exist.
910 Currently the symbols which have the "tag_is_id" flag set are
911 those that don't have an alias. Look harder for the id.
913 * src/output.c (is_identifier): Move to...
914 * src/symtab.c (is_identifier): here.
915 * src/symtab.h, src/symtab.c (symbol_id_get): New.
916 * src/output.c (symbol_definitions_output): Use it to define "id"
918 Remove the definition of "tag_is_id".
919 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
920 "tag_is_id" were used to produce code.
921 We still use "tag" for documentation.
923 2008-11-11 Akim Demaille <demaille@gostai.com>
925 Locations are no longer required by lalr1.cc.
926 * data/lalr1.cc (_b4_args, b4_args): New.
927 Adjust all uses of locations to make them optional.
928 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
929 (AT_CHECK_NAMESPACE): Check the use of locations.
930 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
931 without locations with lalr1.cc.
933 * tests/output.at: Check lalr1.cc with and without location
935 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
938 2008-11-11 Akim Demaille <demaille@gostai.com>
941 * tests/local.at (AT_FULL_COMPILE): New.
942 * tests/actions.at, tests/calc.at, tests/regression.at: Use it.
944 2008-11-11 Akim Demaille <demaille@gostai.com>
946 Support parens in calc++.
947 * doc/bison.texinfo (Calc++ Scanner, Calc++ Parser): Support parens.
948 * examples/calc++/test (run): Check the expected output.
952 2008-11-11 Akim Demaille <demaille@gostai.com>
954 Simplify lalr1.cc since %defines is mandatory.
955 * data/lalr1.cc: Remove useless calls to b4_defines_if.
957 2008-11-11 Akim Demaille <demaille@gostai.com>
960 * TODO (yysyntax_error): New item.
962 2008-11-11 Akim Demaille <demaille@gostai.com>
965 * data/lalr1.cc: Use b4_error_verbose_if instead of #if
968 2008-11-11 Akim Demaille <demaille@gostai.com>
970 Support i18n of the parse error messages.
971 * TODO (lalr1.cc/I18n): Remove.
972 * data/lalr1.cc (yysyntax_error_): Support the translation of the
973 error messages, as done in yacc.c.
974 Stay within the yy* pseudo namespace.
976 2008-11-11 Akim Demaille <demaille@gostai.com>
979 * TODO (single stack, yysyntax_error): New.
981 2008-11-11 Akim Demaille <demaille@gostai.com>
983 Make it possible to return a symbol_type from yylex.
984 * data/lalr1.cc (b4_lex_symbol_if): New.
985 (parse): When lex_symbol is defined, expected yylex to return the
987 * etc/bench.pl.in (generate_grammar_list): Extend to support this
989 (bench_variant_parser): Exercise it.
991 2008-11-11 Akim Demaille <demaille@gostai.com>
993 Remove useless bench case.
994 * etc/bench.pl.in (bench_variant_parser): VARIANT_DESTROY is
997 2008-11-11 Akim Demaille <demaille@gostai.com>
999 Improve display of directives.
1000 * etc/bench.pl.in (parse_term): Don't add useless eol.
1002 2008-11-11 Akim Demaille <demaille@gostai.com>
1004 Use string_cast in the bench.
1005 * etc/bench.pl.in (generate_grammar_list): Define and use
1008 2008-11-11 Akim Demaille <demaille@gostai.com>
1010 Replace yychar with a Boolean.
1011 * data/lalr1.cc (parse::yychar): Replace by...
1012 (parse::yyempty): this.
1014 2008-11-11 Akim Demaille <demaille@gostai.com>
1019 2008-11-11 Akim Demaille <demaille@gostai.com>
1021 Let yytranslate handle the eof case.
1022 * data/lalr1.cc (yytranslate_): Handle the EOF case.
1024 No longer expect yychar to be equal to yyeof_, rather, test the
1025 lookahead's (translated) kind.
1027 2008-11-11 Akim Demaille <demaille@gostai.com>
1029 yychar cannot be empty in yyerrlab.
1030 * TODO (yychar == yyempty_): New.
1031 * data/lalr1.cc: Remove the handling of this case.
1032 This eases forthcoming changes related to yychar and yytranslate.
1034 2008-11-11 Akim Demaille <demaille@gostai.com>
1036 Bench: syntactic sugar for %define/#define.
1037 * etc/bench.pl.in (parse_dirs): Support %d and #d with arguments.
1038 (&bench_push_parser, bench_variant_parser): Use this feature.
1042 2008-11-11 Akim Demaille <demaille@gostai.com>
1044 Less memory pressure on the "list" bench.
1045 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
1046 the values, to limit memory pressure.
1048 2008-11-11 Akim Demaille <demaille@gostai.com>
1050 Introduce make_symbol.
1051 make_symbol provides a means to construct a full symbol (kind,
1052 value, location) in a single shot. It is meant to be a Symbol
1053 constructor, parameterized by the symbol kind so that overloading
1054 would prevent incorrect kind/value pairs. Unfortunately
1055 parameterized constructors do not work well in C++ (unless the
1056 parameter also appears as an argument, which is not acceptable),
1057 hence the use of a function instead of a constructor.
1059 * data/lalr1.cc (b4_symbol_constructor_declaration_)
1060 (b4_symbol_constructor_declarations)
1061 (b4_symbol_constructor_specialization_)
1062 (b4_symbol_constructor_specializations)
1063 (b4_symbol_constructor_definition_)
1064 (b4_symbol_constructor_definitions): New.
1065 Use them where appropriate to generate declaration, declaration of
1066 the specializations, and implementations of the templated
1067 overloaded function "make_symbol".
1068 (variant::variant): Always define a default ctor.
1069 Also provide a copy ctor.
1070 (symbol_base_type, symbol_type): New ctor overloads for value-less
1072 (symbol_type): Now public, so that functions such as yylex can use
1075 2008-11-11 Akim Demaille <demaille@gostai.com>
1077 Inform m4 whether a tag is a valid id.
1078 * src/output.c (is_identifier): New.
1079 (symbol_definitions_output): Use it to define tag_is_id.
1080 But maybe this should be done at m4 level?
1082 2008-11-11 Akim Demaille <demaille@gostai.com>
1084 Test 214 was failing: it greps with a pattern containing [ ]*
1085 which obviously meant to catch spaces and tabs, but contained only
1086 spaces. Tabulations in sources are a nuisance, so to simplify the
1087 matter, get rid of all the tabulations in the Java sources. The
1088 other skeletons will be treated equally later.
1090 * data/java.m4, data/lalr1.java: Untabify.
1091 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
1092 tabulations are no longer generated.
1094 2008-11-11 Paolo Bonzini <bonzini@gnu.org>
1096 * bootstrap.conf: Replace m4/warning.m4 with warnings module.
1097 * configure.ac: Adjust usage.
1098 * lib/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
1099 * src/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
1100 * tests/atlocal.in: Replace $(WARNING_*FLAGS) with $(WARN_*FLAGS).
1102 2008-11-10 Di-an Jan <dianj@freeshell.org>
1104 Workaround Java's ``code too large'' problem for parser tables
1105 in most cases, by using one function per initialization.
1106 * data/java.m4 (b4_typed_parser_table, b4_integral_parser_table): New.
1107 * data/lalr1.java (yypact_, yydefact_, yypgoto_, yydefgoto_,
1108 yytable_, yycheck_, yystos_, yytoken_number_, yyr1_, yyr2_, yyrhs_
1109 yyprhs_, yyrline_, yytranslate_table_): Use b4_integral_parser_table.
1110 (yytname_): Use b4_typed_parser_table.
1111 * doc/bison.texinfo (Java Bison Interface): Add note on Java's
1112 ``code too large'' error.
1114 2008-11-10 Di-an Jan <dianj@freeshell.org>
1116 * NEWS: Document them.
1118 General Java skeleton improvements.
1119 * configure.ac (gt_JAVACOMP): Request target of 1.4, which allows
1120 using gcj < 4.3 in the testsuite, according to comments in
1121 gnulib/m4/javacomp.m4.
1122 * data/java.m4 (stype, parser_class_name, lex_throws, throws,
1123 location_type, position_type): Remove extraneous brackets from
1124 b4_percent_define_default.
1125 (b4_lex_param, b4_parse_param): Remove extraneous brackets from
1126 m4_define and m4_define_default.
1127 * data/lalr1.java (b4_pre_prologue): Change to b4_user_post_prologue,
1128 which marks the end of user code with appropriate syncline, like all
1129 the other skeletons.
1130 (b4_user_post_prologue): Add. Don't silently drop.
1132 (parse): Inline yylex.
1133 * doc/bison.texinfo (bisonVersion, bisonSkeleton): Document.
1134 (%{...%}): Fix typo of %code imports.

1185 For instance, how can a * b / c be parsed if * is %left and / is
1187 (YYERRORCODE, YYFAIL, YYBACKUP): New.
1189 2008-11-10 Akim Demaille <demaille@gostai.com>

1207 2008-11-10 Akim Demaille <demaille@gostai.com>

1270 2008-11-10 Akim Demaille <demaille@gostai.com>
1272 Change the handling of the symbols in the skeletons.
1273 Before we were using tables which lines were the symbols and which
1274 columns were things like number, tag, type-name etc. It is was
1275 difficult to extend: each time a column was added, all the numbers had
1276 to be updated (you asked for colon $2, not for "tag"). Also, it was
1277 hard to filter these tables when only a subset of the symbols (say the
1278 tokens, or the nterms, or the tokens that have and external number
1279 *and* a type-name) was of interest.
1281 Now instead of monolithic tables, we define one macro per cell. For
1282 instance "b4_symbol(0, tag)" is a macro name which contents is
1283 self-decriptive. The macro "b4_symbol" provides easier access to
1286 * src/output.c (type_names_output): Remove.

1330 2008-11-10 Akim Demaille <demaille@gostai.com>
1332 Add %precedence support.
1333 Unfortunately it is not possible to reuse the %prec directive. This
1334 is because to please POSIX, we do not require to end the rules with a
1335 semicolon. As a result,
1339 is ambiguous: either a rule which precedence is that of baz, or a rule,
1340 and then a declaration of the precedence of the token baz.
1342 * doc/bison.texinfo: Document %precedence.
1343 (Precedence Only): New.
1344 * src/assoc.h, src/assoc.c (precedence_assoc): New.

1470 Rely on the state stack to display reduction traces.
1471 To display rhs symbols before a reduction, we used information
1472 about the rule reduced, which required the tables yyrhs and
1473 yyprhs. Now use rely only on the state stack to get the same

1600 2008-11-07 Akim Demaille <demaille@gostai.com>
1602 Add "%define assert" to variants.
1603 This is used to help the user catch cases where some value gets
1604 ovewritten by a new one. This should not happen, as this will
1607 Unfortunately this uncovered a bug in the C++ parser itself: the
1608 lookahead value was not destroyed between two calls to yylex. For
1609 instance if the previous lookahead was a std::string, and then an int,
1610 then the value of the std::string was correctly taken (i.e., the
1611 lookahead was now an empty string), but std::string structure itself
1614 This is now done in variant::build(other&) (which is used to take the
1615 value of the lookahead): other is not only stolen from its value, it
1616 is also destroyed. This incurs a new performance penalty of a few
1617 percent, and union becomes faster again.
1619 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.

1898 Fuse the three stacks into a single one.
1900 In order to make it easy to perform benchmarks to ensure that
1901 there are no performance loss, lalr1.cc is forked into
1902 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
1905 Meanwhile, to make sure that lalr1-fusion.cc is correctly
1906 exercized by the test suite, the user must install a symbolic link
1907 from lalr1.cc to it.
1909 Instead of having three stacks (state, value, location), use a
1910 stack of triples. This considerably simplifies the code (and it
1911 will be easier not to require locations as currently does the C++
1912 parser), and also gives a 10% speedup according to
1913 etc/bench (probably mainly since memory allocation is done once
1914 instead of three times).
1916 Another motivation is to make it easier to destruct properly
1917 semantic values: now that they are bound to their state (hence
1918 symbol type) it will be easier to call the appropriate destructor.
1920 These changes should probably benefit the C parser too.
1922 * data/lalr1.cc: Copy as...
1923 * data/lalr1-fusion.cc: this new file.
1924 (b4_rhs_value, b4_rhs_location): New definitions overriding those
1926 (state_stack_type, semantic_stack_type, location_stack_type)
1927 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
1928 (data_type, stack_type, yystack_): New.
1929 (YYLLOC_DEFAULT, yypush_): Adjust.
1930 (yyerror_range): Now based on data_type, not location_type.
1932 2008-11-03 Akim Demaille <demaille@gostai.com>
1934 Push the state, value, and location at the same time.
1935 This is needed to prepare a forthcoming patch that fuses the three
1938 * data/lalr1.cc (parser::yypush_): New.
1939 (parser::yynewstate): Change the semantics: instead of arriving to
1940 this label when value and location have been pushed, but yystate
1941 is to be pushed on the state stack, now the three of them must
1942 have been pushed before. yystate still must be the new state.
1943 This allows to use yypush_ everywhere instead of individual
1944 handling of the stacks.
1946 2008-11-03 Akim Demaille <demaille@gostai.com>
1948 Prefer references to pointers.
1949 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
1950 definition to use references instead of pointers.
1951 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
1952 Take the value and location as references.
1955 2008-11-03 Akim Demaille <demaille@gostai.com>
1957 stack::size instead of stack::height.
1958 * data/lalr1.cc (stack::height): Rename as...
1959 (stack::size): this.
1960 Fix the output type.
1963 2008-11-03 Akim Demaille <demaille@gostai.com>
1965 Use variants to support objects as semantic values.
1966 This patch was inspired by work by Michiel De Wilde. But he used
1967 Boost variants which (i) requires Boost on the user side, (ii) is
1968 slow, and (iii) has useless overhead (the parser knows the type of
1969 the semantic value there is no reason to duplicate this
1970 information as Boost.Variants do).
1972 This implementation reserves a buffer large enough to store the
1973 largest objects. yy::variant implements this buffer. It was
1974 implemented with Quentin Hocquet.
1976 * src/output.c (type_names_output): New.
1977 (output_skeleton): Invoke it.
1978 * data/c++.m4 (b4_variant_if): New.

1981 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
1982 (b4_char_sizeof, yy::variant): New.
1983 (parser::parse): If variants are requested, define
1984 parser::union_type, parser::variant, change the definition of
1985 semantic_type, construct $$ before running the user action instead
1986 of performing a default $$ = $1.
1987 * examples/variant.yy: New.
1988 Based on an example by Michiel De Wilde.
1990 2008-11-03 Akim Demaille <demaille@gostai.com>
1992 Parameterize the extraction of semantic values.
1993 To make future changes easier, no longer rely on ".TYPE" being the
1994 way to get a semantic value.
1996 * data/c.m4 (b4_symbol_value): New.
1998 * data/c++.m4, data/yacc.c: Use it.
1999 * data/glr.c: Use b4_symbol_value.

2376 * NEWS (2.3b+): Rename to...
2377 (?.?): ... this because we're dropping the "+" version naming scheme,
2378 but, in general, we still can't be sure of our next release name.
2379 * bootstrap: Add a quick hack to remove from .gitignore the
2380 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
2381 entry. This should really be fixed in gnulib instead.
2382 * bootstrap.conf (gnulib_modules): Add gnumakefile.
2383 * configure.ac (AC_INIT): Set version name by invoking
2384 build-aux/git-version-gen.

2414 Fix some .gitignore and .cvsignore problems.
2415 * bootstrap (insert_sorted_if_absent): Replace all uses with...
2416 (insert_vc_ignore): ... this new function, which prepends `/' to all
2417 .gitignore entries before passing them to insert_sorted_if_absent.
2418 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
2419 .cvsignore files are maintained even though Bison developers run
2420 bootstrap while using Git.
2421 * .cvsignore (*.patch *.log log patches applied): Remove, apparently

2441 the first argument because it may become position-dependent, and unset
2442 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
2443 Add comments explaining these issues in more detail.
2445 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

2529 Update to the current gnulib CVS repository, and fix trigraph handling
2531 * bootstrap: Update gnulib CVS repository URL.
2532 (symlink_to_dir): Encapsulate the code that guarantees the destination
2533 directory exists into...
2534 (check_dst_dir): ... this new function, and...
2535 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
2536 fail when copying files into lib/uniwidth/.
2537 * src/output.c (prepare_symbols): When writing yytname muscles, where
2538 symbol names will be encoded in C-string literals, tell quotearg to
2539 escape trigraphs. This used to be the default in gnulib.
2540 * tests/regression.at (Token definitions): Because of the change in
2541 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
2542 escapes trigraphs in symbol names. Thus, yytname no longer has
2543 trigraphs unnecessarily doubly escaped. Update test case output.
2544 Extend test case to be sure Bison's own error messages will no longer
2545 have trigraphs in symbol names unnecessarily escaped once.

2560 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
2561 consistency. Update the -g and -x entries now that they take
2562 arguments. Use brackets to indicate optional arguments.
2563 * src/getargs.c (usage): Explain the relationship between arguments of
2564 long and short options more completely. Document --defines and -d
2565 separately since the former takes an argument but, for POSIX Yacc, the
2567 (short_options): Let -W take an optional argument like --warnings.

2585 Fix the handling of $opt which resulted in all the argument to be
2586 considered as optional.
2588 2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>

2624 * data/yacc.c: Clean up whitespace in the output a little.
2625 (yypstate_allocated): Define for impure push parsers regardless of
2626 whether the pull interface is also requested.
2627 * tests/push.at (Push Parsing: Multiple impure instances): Extend to
2628 check impure push parsers without the pull interface.
2630 * data/yacc.c (yypstate_new): Don't try to invoke yyerror since

3167 of the string-replace template directly.
3168 (xsl:template name="output-edge"): Likewise.
3169 (xsl:template name="escape"): New, escapes backslashes and newlines in
3170 addition to quotation marks.
3171 * src/graphviz.c (start_graph, output_node, output_edge): Add
3172 whitespace to output for legibility.
3174 Make xml2text.xsl and --report produce the same output, and remove the
3175 XML "conflicts" element since a conflict summary is easily extracted
3177 * data/xslt/bison.xsl: New.
3178 (xsl:template match="state" mode="bison:count-conflicts): New.
3179 * data/xslt/xml2text.xsl: Import bison.xsl.
3180 (xsl:template match="bison-xml-report"): Instead of styling the
3181 "conflicts" element, style the "automaton" element with mode
3182 "conflicts". Unlike the former, the latter lists S/R and R/R
3183 conflicts for a state on the same line.
3184 (xsl:template match="conflicts"): Remove.
3185 (xsl:template match="conflict"): Remove.
3186 (xsl:template match="terminal"): Line-wrap the list of rules in which
3187 the terminal is used.
3188 (xsl:template match="nonterminal"): Likewise for nonterminals.

3198 (xsl:template match="conflict"): Remove.
3199 (xsl:template match="automaton" mode="conflicts"): New.

3202 * src/conflicts.h (conflicts_output_xml): Remove prototype.
3203 * src/print-xml.c (print_xml): Don't invoke conflicts_output_xml.
3204 * src/print.c (print_grammar): Consistently wrap at the 66th column so
3205 the corresponding XSLT is easier. Also, never wrap between a word and
3206 the comma that follows it.

3210 Improve C++ namespace support. Discussed starting at
3211 <http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>.
3212 * data/c++.m4: (b4_namespace_ref, b4_namespace_open,
3213 b4_namespace_close): New macros that interpret the %define variable
3214 "namespace" so its value can contain "::" to indicate nested

3218 * data/lalr1.cc (b4_namespace): Likewise.
3219 * data/location.cc (b4_namespace): Likewise.
3220 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
3221 inside a new table in the general %define entry. Document `%define
3222 namespace' there as well. Point the %name-prefix entry to it since it
3223 explains it more completely in the case of C++.
3224 (C++ Bison Interface): Mention `%define namespace' instead of
3226 (Table of Symbols): Remove the `%define push_pull' entry. The %define
3228 * tests/c++.at (Relative namespace references): New test case.
3229 (Absolute namespace references): New test case.
3230 (Syntactically invalid namespace references): New test case.
3231 * tests/input.at (C++ namespace reference errors): New test case.

3241 than 0 for the sake of synchronizing #line's, and define
3242 b4_percent_define_syncline(VARIABLE).
3243 (b4_percent_define_check_values): Use b4_percent_define_get_loc.
3244 * src/muscle_tab.c (muscle_syncline_grow): New.
3245 (muscle_code_grow): Use muscle_syncline_grow.

3252 (muscle_percent_define_default): Record defining location as line 1
3253 rather than 0 for the sake of synchronizing #line's, and define
3254 b4_percent_define_syncline(VARIABLE).
3255 (muscle_percent_define_check_values): Use
3256 muscle_percent_define_get_loc.
3257 * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype.
3258 (muscle_percent_define_get_syncline): Prototype.

3266 Fix some error-reporting macro bugs.
3267 * data/bison.m4 (b4_cat): New.
3268 (b4_error, b4_error_at): Use b4_cat to send error directives directly
3269 to stdout so they don't become arguments to other macros. Update
3270 comments and add examples.
3271 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
3273 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
3274 after printing the error directive so that M4 doesn't report subsequent
3275 problems that are induced by this problem.
3276 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
3277 instead of just in them. Recognize @\n in both places. Both expand to
3278 the empty string. Needed by b4_cat.
3279 * tests/skeletons.at (Complaining during macro argument expansion):
3281 (Fatal errors make M4 exit immediately): New test case.
3283 2007-10-04 Joel E. Denny <jdenny@ces.clemson.edu>

3310 Pull Parser Function, Parser Create Function, Parser Delete Function):
3311 Update declarations.
3312 (Decl Summary, Table of Symbols): Replace %push-parser and

3319 * data/push.c: ... to here and compute them from the value of the
3320 %define variable push_pull.
3321 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
3322 parsing requests here...
3323 * data/yacc.c: ... hack this to switch to push.c any time
3324 b4_use_push_pull_flag or the %define variable push_pull is set. This
3325 will go away when we mv push.c yacc.c.
3326 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
3327 push parsing is not supported since unused %define variables are
3329 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
3330 * src/muscle_tab.h (muscle_percent_define_check_values): Update

3375 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
3377 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
3379 * src/print-xml.c: Prefer "const" after types; that's more consistent.
3380 (xml_printf): Indent just 1 space for level.
3381 (e_char, xlate_char): Remove.
3382 (xml_escape_string): Rewrite to avoid undefined behavior (used

3435 2006-08-18 Paul Eggert <eggert@cs.ucla.edu>
3436 Bruno Haible <bruno@clisp.org>
3438 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists
3439 and is a script that invokes bison. Tighten the code. Add comments.
3441 2007-08-28 Joel E. Denny <jdenny@ces.clemson.edu>

3453 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
3455 In impure push mode, don't allow more than one yypstate to be allocated
3456 since multiple impure parsers would corrupt yynerrs.
3457 * data/push.c (yypstate_allocated): New static global variable
3459 (yypull_parse): If yypstate_new returns 0, don't report it as memory
3460 exhaustion if yypstate_allocated is 1, but still return 2.
3461 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
3462 already 1. Otherwise, set it to 1.
3463 (yypstate_delete): Set it to 0.

3538 Get rid of broken %no-parser, -n, and --no-parser implementation and
3540 * TODO: Don't mention them.
3541 * doc/bison.1: Likewise.
3542 * doc/bison.texinfo (Decl Summary): Likewise.
3543 (Bison Options): Likewise.
3544 (Option Cross Key): Likewise.
3545 * src/getargs.c (no_parser_flag): Remove global variable.
3546 (usage): Don't print description of -n and --no-parser.
3547 (long_options): Remove --no-parser entry here.
3548 (getargs): Remove -n case in the switch here.
3549 * src/getargs.h (no_parser_flag): Remove extern.
3550 * tests/regression.at (Web2c Actions): Remove comment that mentions
3553 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
3555 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
3556 name user variables starting with `yy'. Just pass NULL instead of a
3557 dummy local &yylval to yypush_parse.
3558 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
3561 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
3563 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
3564 true since it's then always used regardless of whether yyoverflow is
3565 defined. Reported by Christian Burger at
3566 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
3567 * THANKS: Add Christian Burger.
3569 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3570 node names: say "Decl Summary" not "Bison Declaration Summary".
3572 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
3574 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
3575 determine whether this function has already complained about an invalid
3576 value for a %define boolean variable, don't check whether Bison has
3577 ever examined the value. As written, the check was a tautology.
3578 Instead, record and check for this complaint using a separate muscle.
3580 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
3582 Fix push parsing memory leak reported by Brandon Lucia at
3583 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
3584 * THANKS: Add Brandon Lucia.
3585 * data/push.c (yypstate_delete): Free the stack if it was reallocated
3586 but the parse never completed and thus freed it.
3587 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
3588 * tests/testsuite.at: Include push.at.
3589 * test/push.at: New.
3590 (Push Parsing: Memory Leak for Early Deletion): New test case.
3592 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
3594 Improve handling of multiple S/R conflicts in the same state and of S/R
3595 conflicts involving multiple reductions.
3596 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
3597 set for a state here or Bison will abort if it is reassigned on a
3598 later conflicted reduction in the same state.
3599 Similarly, don't finalize and assign the solved conflicts report here
3600 or it will be lost if it is reassigned on a later conflicted reduction
3602 (set_conflicts): Instead, assign them both here after all S/R conflicts
3603 in the state have been fully examined.
3604 * src/print.c (shift_set): Rename to...
3605 (no_reduce_set): ... this.
3606 (print_reductions): Update for rename, and add %nonassoc error action
3607 tokens to no_reduce_set so that, when printing the first remaining
3608 reduction on an error action token, the reduction is enclosed in
3610 (print_results): Update for rename.
3611 * tests/conflicts.at (Solved conflicts report for multiple reductions
3612 in a state): New test case.
3613 (%nonassoc error actions for multiple reductions in a state): New test
3616 * src/main.c (main): Don't depend on C99 features.
3618 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
3620 * build-aux/.cvsignore: Add compile.
3621 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
3624 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
3626 * bootstrap (slurp): Create target directories that don't exist.
3627 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
3629 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
3631 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
3633 * closure.c (closure): Likewise.
3634 * state.h (reductions): Comment sorting of rules.
3635 (state): Comment sorting of items.
3637 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
3639 Fix C++ test cases after recent Gnulib changes. Discussed starting at
3640 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
3641 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
3642 definition in order to avoid Gnulib headers since we don't use config.h
3644 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
3645 rather than AT_DATA so that config.h is included.
3647 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
3649 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
3650 instead of fprintf. Guard these functions with #if YYDEBUG instead of
3651 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
3652 and so that YYFPRINTF is guaranteed to be defined here.
3654 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
3656 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
3658 (muscle_percent_define_check_values): ... this more helpful function.
3659 Again, it's not used yet, but it will be.
3660 * src/muscle_tab.h: Likewise.
3662 Improve some comments in parser table construction.
3663 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
3664 (generate_states): Don't mention ruleset, which is internal to closure.
3665 * src/closure.c (closure): Explain sorting of core and itemset, which
3666 is required for this function to behave correctly.
3667 * src/closure.h (closure): Mention sorting.
3669 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
3671 * src/lalr.c (state_lookahead_tokens_count): For code readability,
3672 move the check for disabled transitions to an aver since conflict
3673 resolution hasn't happened yet.
3675 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3676 labels a state as inconsistent just because it has error transitions.
3677 The original form of this check appeared in revision 1.1 of lalr.c,
3678 which was committed on 1991-12-21. Now (at least), changing the
3679 consistency label on such a state appears to have no useful effect in
3680 any of the places it is examined, which I enumerate below. The key
3681 point to understanding each item in this enumeration is that a state
3682 with an error transition is labelled consistent in the first place only
3683 if it has no rules, so the check cannot matter for states that have
3684 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3685 to try to identify its conflicts, and a state must have *rules* to have
3686 conflicts. (2) Labelling a state as inconsistent will affect how
3687 action_row sets the default *rule* for the state. (3) Labelling a
3688 state as inconsistent will cause build_relations to add lookback edges
3689 to *rules* in that state.
3690 * src/state.h (struct state): Word the comment for member consistent
3693 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
3695 Don't depend on C99 features.
3696 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
3697 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
3698 * src/reader.c (check_and_convert_grammar): Fix for-loop.
3699 * src/state.c (state_mark_reachable_states): Fix for-loop.
3700 (state_remove_unreachable_states): Fix for-loop.
3702 Don't widen struct state with member reachable just to temporarily
3703 record reachability. Instead, use a local bitset.
3704 * src/state.h (struct state): Remove member.
3705 * src/state.c (state_new): Don't initialize it.
3706 (state_mark_reachable_states): Rename to...
3707 (state_record_reachable_states): ... this, and use bitset.
3708 (state_remove_unreachable_states): Use bitset.
3710 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
3712 * src/Makefile.am (yacc): Quote target action commands properly so
3713 that the yacc script isn't corrupt. Reported by Hans Aberg at
3714 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
3716 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
3717 the case of pure parsers. Reported by Frans Englich at
3718 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
3719 * THANKS: Add Frans Englich.
3721 * NEWS (2.3a+): In the %code entry, reference section `Bison
3722 Declaration Summary' from the manual now since the %code summary has
3724 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
3725 in the rules section must be terminated by semicolons.
3727 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
3729 Extend the front-end API for %define variables to more completely
3730 mirror the back-end. This will be useful in the future.
3731 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
3732 Update comments to mention the new front-end counterparts of these

3742 implementation more closely.
3743 (muscle_percent_define_invalid_value): New function.
3744 * src/muscle_tab.h (muscle_percent_define_get,
3745 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
3748 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
3750 * NEWS (2.3a+): Mention yesterday's state-removal change.
3751 (2.3a): Remove the %language entry, which was added after 2.3a.
3752 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
3753 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
3754 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
3755 tests/existing.at: Update copyright date.
3757 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
3759 If conflict resolution makes states unreachable, remove those states,
3760 report rules that are then unused, and don't report conflicts in those
3762 * src/conflicts.c, src/conflicts.h (conflicts_update_state_numbers):
3763 New global function.
3764 * src/lalr.c, src/lalr.h (lalr_update_state_numbers): New global

3776 * tests/existing.at (GNU pic Grammar): Update test case output now that
3777 an unused rule is discovered.
3779 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
3781 Minor code cleanup in parser table construction.
3782 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
3783 (new_itemsets, save_reductions): Update for rename to nitemset.
3784 * src/closure.c (nritemset): Rename to...
3785 (nitemset): ... this since the "r" appears to meaningless and isn't
3786 used in the comments.
3787 (closure): Update for rename.
3788 * src/closure.h (nritemset): Update extern to...
3789 (nitemset): ... this.

3795 2007-04-04 Paul Eggert <eggert@cs.ucla.edu>
3797 * THANKS: Use ASCII for Sebastien Fricker's name. Bison source
3798 still sticks to ASCII. Sorry!

3834 Rename method names according to previous patch.
3835 (Java Scanner Interface): Describe "%code lexer" instead of
3836 "%pure-parser" and "%define single_class".
3837 (Java Differences): Mention "%code lexer".

3847 (AT_BISON_OPTION_POPDEFS): Pop it.
3849 2007-03-07 Juan Manuel Guerrero <juan.guerrero@gmx.de>
3851 DJGPP spefic issue. Inhibit the use of disallowed characters for
3852 file name genertion on Win98, WinXP, etc. These are |<>":?*\
3853 and concern testsuite case 46.

3862 values are interpreted.
3863 * doc/bison.texinfo (Decl Summary): Clean up and extend %define
3864 documentation a little more.

3872 %define and %code directives.
3874 Make it easy to share %define boolean variables between the front-end
3875 and back-end. Though not used yet, this will be useful in the future.
3876 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
3877 Bison uses of names rather than just skeleton uses of names.
3878 (b4_percent_define_get, b4_percent_define_ifdef): Rename
3879 b4_percent_define_skeleton_variables(VARIABLE) to
3880 b4_percent_define_bison_variables(VARIABLE).

3885 * src/muscle_tab.c, src/muscle_tab.h (muscle_percent_define_flag_if,
3886 muscle_percent_define_default): New functions mimicking
3887 b4_percent_define_flag_if and b4_percent_define_default.
3889 For %define variables, report locations for invalid values and
3891 * data/bison.m4 (b4_percent_define_flag_if): Read
3892 b4_percent_define_loc(VARIABLE) to report the location of an invalid
3894 (b4_percent_define_default): Save a special location in
3895 b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE

3908 * tests/input.at (%define errors): Update expected output.
3909 * tests/skeletons.at (%define boolean variables: invalid skeleton
3910 defaults): New test case.
3912 2007-02-28 Joel E. Denny <jdenny@ces.clemson.edu>
3914 * src/print.c (lookahead_set, state_default_rule): Remove.
3915 (print_reductions): Replace state_default_rule invocation with
3916 equivalent use of yydefact, which was computed in token_actions in
3918 (print_results): Don't allocate lookahead_set.
3920 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
3922 * data/lalr1.java: Prefix all private members with yy.
3924 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
3926 Use YYFPRINTF instead of fprintf where appropriate. Reported by
3927 Sebastien Fricker at
3928 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
3929 * THANKS: Add Sebastien Fricker.
3930 * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
3931 * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must

3944 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
3946 Undo my 2007-02-07 change, switching back to the c-strcase module
3947 introduced in the 2007-02-03 change. Bruno Haible reported that
3948 the 2007-02-07 change would be dangerous in Turkish if we add a
3949 language whose name contains "i", since "i" is not lowercase "I"
3951 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
3952 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
3953 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
3954 * m4/.cvsignore: Remove strcase.m4.
3955 * src/getargs.c: Revert 2007-02-07 change, as follows.
3956 Include c-strcase.h.
3957 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
3959 2007-02-11 Bruno Haible <bruno@clisp.org>
3961 Enable the Java related testsuite tests when the only Java compiler
3962 found is a gcj < 4.3. Discussed at
3963 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
3964 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
3966 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
3968 * data/Makefile.am: Update copyright date.
3969 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
3970 yypstate_new returns NULL.
3971 (yypstate_new): Return NULL if malloc does.
3972 * src/reader.c (packgram): Move translation of rule actions from the
3973 beginning of packgram to...
3974 (check_and_convert_grammar): ... here right before packgram is invoked
3975 so it's easier to write more complete comments, and remove redundant
3978 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
3980 As in semantic actions, make @$ in %initial-action, %destructor, and
3981 %printer imply %locations.
3982 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
3984 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
3985 (@$ in %initial-action implies %locations,
3986 @$ in %destructor implies %locations,
3987 @$ in %printer implies %locations): ... these new test cases.
3989 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
3991 Undo most of the 2007-02-03 change, switching to the strcase module
3992 now that gnulib strcase has been fixed.
3993 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
3994 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
3995 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
3996 * m4/.cvsignore: Add strcase.m4.
3997 * src/getargs.c: Revert 2007-02-03 change, as follows.
3998 Don't include c-strcase.h.
3999 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
4000 strcasecmp has "unspecified behavior" outside the POSIX locale,
4001 but it works fine in practice if at least one argument is ASCII,
4002 as is the case in Bison.
4004 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
4006 * tests/java.at: Skip tests if only one of javac/java is present.
4007 Reported by Joel E. Denny.
4008 * tests/atlocal.in: Adjust copyright years.
4010 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
4012 * data/lalr1.java (Stack): Work around old verifiers that disallow
4013 access to the private fields of an inner class, from the outer class.
4014 We can make Stack's fields public because user code doesn't have access
4015 to the instance of Stack used by parse(). Reported by Paul Eggert.
4017 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
4019 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
4020 the right spot for these files?
4021 * bootstrap.conf (gnulib_modules): Add c-strcase.
4022 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
4024 * src/getargs.c: Include c-strcase.h.
4025 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
4026 to avoid unspecified behavior.
4028 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
4030 * doc/bison.texinfo (Decl Summary): Correct typo.
4032 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
4034 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
4035 Complain if the value does not match empty, "true" or "false".

4066 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
4069 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
4070 at_directive_argv arguments so these no longer have to be global
4071 variables. Also, update the implementation for the following changes.
4072 (fail_for_at_directive_too_many_args,
4073 fail_for_at_directive_too_few_args): Add at_directive_name argument.
4074 (at_directive_name): Remove as at_directive_argv[0] will be used for
4076 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
4077 for the directive name.
4078 (at_directive_argc, at_directive_argv): Make these local within
4079 skel_lex instead of global.
4080 (INITIAL): Update directive start action for above changes.
4081 (SC_AT_DIRECTIVE_ARG): Rename to...
4082 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
4083 (SC_AT_DIRECTIVE_SKIP_WS): Update.
4084 (scan_skel): Move yylex_destroy to...
4085 (skel_scanner_free): ... here.
4086 * tests/skeletons.at (installed skeleton file name): Rename to...
4087 (installed skeleton file names): ... this.
4089 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
4091 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4092 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
4093 Summary" not "Directives".
4094 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
4095 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
4096 since the former is now the more complete one.
4097 (Prologue Alternatives): Likewise and do the same for %defines.
4098 (Table of Symbols): Add summary of %code, add summary of %define, and
4099 move full %code documentation to...
4100 (Decl Summary): ... here for consistency with other entries in these
4102 Move %define entry in order to keep this list alphabetized.
4103 Reword %define entry a little to put less emphasis on the skeleton
4104 concept, which most users shouldn't have to think about.
4106 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
4108 Adjust to recent gnulib changes.
4109 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
4110 Add string.h, string_.h, unistd_.h, wchar_.h.
4111 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
4112 * src/system.h: Don't include <stpcpy.h>; this is now done by
4115 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
4117 Simplify implementation of unqualified %code, implement macros for
4118 uniform treatment of boolean %define flags. Document %define.
4119 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
4120 b4_percent_code_ifdef): New.
4121 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
4122 * data/c++.m4: Define default value for global_tokens_and_yystype.
4123 * data/glr.cc: Likewise.
4124 * data/location.cc: Use b4_percent_define_flag_if.
4126 * doc/bison.texinfo (Decl Summary): Document %define.
4128 * src/parse-gram.y (Unqualified %code): Change muscle name to
4130 (content.opt): Default to empty.
4132 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
4134 Implement support for relative and absolute skeleton file names.
4135 Discussed starting at
4136 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
4137 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
4138 (Bison Options): Document in --skeleton entry.
4139 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
4140 full_skeleton can't necessarily hold all of pkgdatadir.
4141 If the specified skeleton file name contains a `/', don't prepend
4143 * src/parse-gram.y (prologue_declaration): If the specified skeleton
4144 file name contains a `/', prepend the grammar file directory.
4145 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
4146 * skeletons.at: New file.
4147 (relative skeleton file names): New test case.
4148 (installed skeleton file names): New test case.
4149 * tests/testsuite.at: Include skeletons.at.
4151 * bootstrap: Update copyright to 2007.
4153 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
4155 * bootstrap: Remove occurrences of .#bootmp from the files.
4157 2007-01-17 Akim Demaille <akim@epita.fr>
4159 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
4161 Use per-type %printer.

4187 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
4188 and Joel E. Denny <jdenny@ces.clemson.edu>
4190 Clean up %define and %code implementation in M4 some. Most
4191 importantly, rename all related macros to be in the b4_percent_define
4192 and b4_percent_code namespaces. Also, complete support for `.' in
4193 %define variable names and %code qualifiers.
4194 * data/bison.m4 (b4_check_user_names): Check for special
4195 "SKELETON-NAMESPACE(name)" macros instead of using two nested
4197 (b4_get_percent_define, b4_get_percent_code): Rename to...
4198 (b4_percent_define_get, b4_percent_code_get): ... these.
4199 Extend documentation with examples.
4200 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
4201 b4_percent_define_skeleton_variables and
4202 b4_percent_code_skeleton_qualifiers.
4203 Expect any value for the %define variable `foo' to be stored in the
4204 macro named `b4_percent_define(foo)'; expect any %code blocks for the
4205 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
4206 expect any unqualified %code blocks to be stored in a macro named
4207 `b4_percent_code_unqualified'.
4208 Use m4_indir so that %define variable names and %code qualifiers can
4209 contain `.', which is allowed by the grammar parser.
4210 (b4_percent_define_default): New macro to set a default value for a
4212 (m4_wrap): Update wrapped code, and fix some underquoting.
4213 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
4214 Expect grammar uses of %define variables and %code qualifiers to be
4215 defined in b4_percent_define_user_variables and
4216 b4_percent_code_user_qualifiers.
4217 * data/c++.m4: Use b4_percent_define_default rather than
4218 m4_define_default. Fix some underquoting. Skeleton usage of %define
4219 variable define_location_comparison now implies skeleton usage of
4220 %define variable filename_type.
4221 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4222 data/push.c, data/yacc.c: Update macro names.
4223 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
4226 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
4228 DJGPP specific issues.
4230 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
4231 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
4233 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4235 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
4236 run parsers in all tests so that Valgrind is invoked during
4237 maintainer-check-valgrind.
4238 (Duplicate representation of merged trees): Free all semantic values.
4239 (Duplicated user destructor for lookahead): Likewise.
4241 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4243 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
4244 command-line prefix.
4245 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
4246 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
4247 miss Valgrind messages.
4248 (Exploding the Stack Size with Malloc): Likewise.
4250 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4252 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
4253 locals. Reported by Juan Manuel Guerrero at
4254 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
4255 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
4256 Fix some indentation also.
4257 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
4258 explaining this issue.
4260 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
4261 and Joel E. Denny <jdenny@ces.clemson.edu>
4263 Simplify union and prologue handling, and escape union and lex/parse
4264 params with digraphs.
4265 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
4266 values to the empty string since these are no longer guaranteed
4267 initialized by the front-end.
4268 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
4269 braces around b4_user_stype since this is no longer done by the
4271 * src/files.c, src/files.h (pre_prologue_obstack,
4272 post_prologue_obstack): Remove.
4273 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
4274 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
4275 with digraphs. This fixes lex params and parse params.
4276 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
4277 * src/output.c (prepare): Remove muscle insertion of the prologues.
4278 (output): Remove freeing of pre_prologue_obstack and
4279 post_prologue_obstack.
4280 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
4281 than prologue_augment for prologue parsing so you don't need prologue
4283 (grammar_declaration): For %union RHS, use `braceless' instead of
4284 "{...}" so that braces are already stripped and code is escaped with
4286 * src/reader.c (prologue_augment): Remove.
4287 (reader): Remove initialization of pre_prologue_obstack and
4288 post_prologue_obstack.
4289 * src/reader.h (prologue_augment): Remove.
4291 * data/c.m4: Remove stray parenthesis.
4293 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4295 Remove quotes from variables names in %define directives and from
4296 qualifiers in %code directives, and restrict the characters that are
4297 allowed in them to M4-friendly ones. For %define, continue to support
4298 the quoted form as a deprecated feature. Discussed starting at
4299 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
4300 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
4302 * doc/bison.texinfo (Prologue Alternatives): Update.
4303 (Decl Summary): In %defines entry, update mention of `%code requires'
4304 and `%code provides'.
4305 (C++ Location Values): Update %define uses.
4306 (Calc++ Parser Interface): Likewise.
4307 (Calc++ Parser): Likewise, and update `%code requires' uses.
4308 (Table of Symbols): Update %code documentation.
4309 * src/parse-gram.y (prologue_declaration): For %define variables, use
4310 `variable' instead of `STRING'.
4311 (grammar_declaration): For %code qualifiers, use `ID' instead of
4313 (variable): New nonterminal that takes an `ID' or a `STRING'.
4314 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
4316 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
4317 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
4318 (%define errors): Update %define uses.
4320 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4322 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
4323 instead of muscle_insert for %define values so that M4-special
4324 characters are replaced with digraphs.
4325 * tests/input.at (%define errors): Extend to check weird values.
4327 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4329 Instead of having skeletons declare all valid %define variables and
4330 %code qualifiers, provide macros that retrieve the associated values
4331 and build these lists automatically. Thus Bison will now warn when a
4332 variable or qualifier is not used by the skeleton in the current
4333 invocation regardless of whether it might sometimes be used by that
4334 skeleton in other invocations. Also, move all %define value macros to
4335 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
4336 form, which is replaced by %code.
4337 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
4338 (b4_check_user_names): ... this, and change the series of valid name
4339 arguments to a single list argument for names used in the skeleton
4340 similar to the existing list argument for names used in the grammar.
4341 Warn instead of complaining.
4342 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
4343 values and %code code, to format %code code properly, and to build
4344 lists of all %define variables and %code qualifiers used in the
4345 skeleton: b4_skeleton_percent_define_variables and
4346 b4_skeleton_percent_code_qualifiers.
4347 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
4349 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
4350 the skeleton names lists can finish building first. In place of
4351 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
4352 expect the lists b4_user_percent_define_variables and
4353 b4_user_percent_code_qualifiers.
4354 * data/c++.m4: Where setting default values for b4_parser_class_name,
4355 b4_location_type, b4_filename_type, b4_namespace, and
4356 b4_define_location_comparison, update their names to the
4357 b4_percent_define_ namespace.
4358 * data/glr.c: Don't use b4_check_percent_define_variables and
4359 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4360 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
4361 (b4_parser_class_name, b4_namespace): Define these using
4362 b4_get_percent_define for parser_class_name and namespace.
4363 * data/location.cc: Use b4_get_percent_define.
4364 * data/push.c: Don't use b4_check_percent_define_variables and
4365 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4366 * data/yacc.c: Likewise, and don't call m4_exit in
4367 b4_use_push_for_pull_if or m4_wrap code will never execute.
4368 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
4370 (muscle_grow_user_name_list): ... this for consistency with the
4371 terminology used in bison.m4.
4372 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
4373 %define variable names, and rename muscle used_percent_define_variables
4374 to user_percent_define_variables.
4375 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
4376 user_percent_code_qualifiers.
4378 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
4379 {CODE} form is no longer accepted.
4380 * tests/input.at (Reject bad %code qualifiers): Rename to...
4381 (Reject unused %code qualifiers): ... this, and update test output.
4382 (%define error): Update test output.
4384 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
4386 Check for unrecognized %define variables similar to checking for
4387 unrecognized %code qualifiers. Check for redefined %define variables.
4388 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
4390 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
4391 (b4_check_percent_define_variables): New, also wraps it.
4392 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
4393 variables using b4_check_percent_define_variables.
4394 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
4395 all those exercised in the test suite and all those listed in the
4396 `Default values' section of c++.m4. Are there others?
4397 * data/push.c, data/yacc.c: Declare no valid %define variables.
4398 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
4399 similar to muscle_find, but it works even when the muscle stores a
4401 (muscle_grow_used_name_list): New function for constructing the used
4402 name list muscles that b4_check_for_unrecognized_names requires.
4403 * src/parse-gram.y (prologue_declaration): Warn if a variable is
4404 %define'd more than once. Define the b4_used_percent_define_variables
4405 muscle with muscle_grow_used_name_list.
4406 (grammar_declaration): Abbreviate %code code with
4407 muscle_grow_used_name_list.
4408 * tests/input.at (%define errors): New.
4410 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4412 Provide warn_at, complain_at, and fatal_at function callbacks to the
4413 skeletons, and use this for %code qualifier complaints.
4414 * data/bison.m4 (b4_error_at): New, invoked by...
4415 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
4416 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
4417 @fatal_at(...@) directives.
4418 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
4419 qualifiers in b4_used_percent_code_qualifiers and to use
4421 * src/location.c, src/location.h (boundary_set_from_string): New global
4423 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
4425 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
4426 to b4_used_percent_code_qualifiers.
4427 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
4429 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
4430 (lineno): Rename to...
4431 (out_lineno): ... this so I don't misunderstand it again.
4432 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
4433 here; these newlines are in the input but not the output file.
4434 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
4435 (at_directive_perform): ... this new static function, and add handling
4436 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
4438 * tests/input.at (Reject bad %code qualifiers): Update test output with
4439 locations and extend.
4441 * tests/output.at (Output file name: [, Output file name: ]): Remove
4442 bogus comment about these tests failing.
4444 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4446 Clean up b4_check_percent_code_qualifiers a little.
4447 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
4448 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
4449 documentation and add examples.
4450 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
4453 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
4455 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
4456 unreliable -- especially when they're hidden inside another macro.
4457 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
4458 data/c.m4: Remove m4_divert(-1).
4459 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4460 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
4461 m4_divert_push(0) and m4_divert_pop(0).
4462 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
4463 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
4464 pushed and popped by m4sugar, should be first on the stack.
4466 Provide warn, complain, and fatal function callbacks to the skeletons.
4467 This provides more flexibility than m4_fatal, improves the error
4468 message format, and captures messages for translation. Discussed
4470 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
4471 * data/bison.m4 (b4_error): New, invoked by...
4472 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
4473 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
4474 directives. Because these M4 macros might be called when the current
4475 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
4476 the previous removal of uses of m4_divert, which caused trouble.
4477 (b4_check_percent_code_qualifiers): Use b4_complain instead of
4478 m4_fatal to report unrecognized %code qualifiers.
4479 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
4480 push parser requests.
4481 * data/glr.c: Use b4_complain instead of m4_fatal to report
4482 non-deterministic push parser requests.
4483 Update @output usage to @output(...@) form.
4484 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
4485 report missing %defines. Update @output usage to @output(...@) form.
4486 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
4488 * src/main.c (main): Invoke skel_scanner_free.
4489 * src/scan-skel.h (skel_scanner_free): Prototype new function.
4490 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
4491 obstack_for_string from flex-scanner.h.
4492 (YY_DECL): Use to declare skel_lex static.
4493 (decode_at_digraphs): Remove; now handled in the new
4494 SC_AT_DIRECTIVE_ARG start condition.
4495 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
4497 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
4498 at_directive_argv): New static globals.
4499 (INITIAL): Use fail_for_invalid_at.
4500 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
4501 recognize the start of a generalized `@directive(...@)' form and
4503 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
4504 directive args (using the new obstack_for_string), to decode the
4505 contained @ diagraphs, and to perform the directive. It recognizes
4506 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
4508 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
4509 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
4511 (scan_skel): Initialize obstack_for_string on the first call.
4512 (skel_scanner_free): New function to free obstack_for_string.
4513 * tests/input.at (Reject bad %code qualifiers): Update test output.
4515 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
4517 Consolidate the 4 prologue alternative directives (%code, %requires,
4518 %provides, and %code-top) into a single %code directive with an
4519 optional qualifier field. Discussed at
4520 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
4521 * NEWS (2.3a+): Rewrite the existing entry for the prologue
4523 * doc/bison.texinfo (Prologue Alternatives): Update.
4524 (Decl Summary): Update to %code "requires" and %code "provides".
4525 (Calc++ Parser): Update to %code "requires".
4526 (Table of Symbols): Remove entries for %requires, %provides, and
4527 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
4528 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
4529 are replaced by b4_percent_code_provides and b4_percent_code_requires,
4530 which are skeleton-specific.
4531 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
4532 declare what %code qualifiers it supports and to complain if any other
4533 qualifiers were used in the grammar.
4534 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
4535 and b4_user_code([b4_percent_code_provides]) in place of
4536 b4_user_requires and b4_user_provides.
4537 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
4538 Add b4_user_code([b4_percent_code_top]) and
4539 b4_user_code([b4_percent_code]).
4540 Invoke b4_check_percent_code_qualifiers.
4541 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4542 PERCENT_REQUIRES): Remove.
4543 (grammar_declaration): Remove RHS's for %code-top, %provides, and
4544 %requires. Rewrite the %code RHS as the unqualified form defining the
4545 muscle b4_percent_code. Add another RHS for the qualified %code form,
4546 which defines muscles of the form b4_percent_code_QUALIFIER and the
4547 b4_used_percent_code_qualifiers muscle.
4548 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4549 PERCENT_REQUIRES): Remove.
4550 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
4551 %code "requires" and %code "provides".
4552 * tests/input.at (Reject bad %code qualifiers): New.
4554 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4556 Use the new code_props interface for destructors and printers.
4557 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
4558 printer_location members, and change the type of the destructor and
4559 printer members to code_props.
4560 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
4561 symbol_printer_get, semantic_type_destructor_set,
4562 semantic_type_printer_set, default_tagged_destructor_set,
4563 default_tagless_destructor_set, default_tagged_printer_set,
4564 default_tagless_printer_set): Use code_props in arguments and return
4565 types in place of char const * and location.
4566 (symbol_destructor_location_get, symbol_printer_location_get): Remove
4567 since the locations are now contained in the return of
4568 symbol_destructor_get and symbol_printer_get.
4569 * src/output.c (symbol_destructors_output, symbol_printers_output):
4571 (symbol_code_props_output): ... this to eliminate duplicate code.
4572 (output_skeleton): Update to use symbol_code_props_output.
4573 * src/reader.c (symbol_should_be_used): Update use of
4574 symbol_destructor_get.
4575 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4576 Update uses of the various _destructor_set and _printer_set functions.
4577 * src/symtab.c: (default_tagged_destructor_location,
4578 default_tagless_destructor_location, default_tagged_printer_location,
4579 default_tagless_printer_location): Remove since we...
4580 (default_tagged_destructor, default_tagless_destructor,
4581 default_tagged_printer, default_tagless_printer): ... change the type
4582 of these to code_props.
4583 (symbol_new, semantic_type_new, symbol_destructor_set,
4584 semantic_type_destructor_set, symbol_destructor_get,
4585 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
4586 symbol_check_alias_consistency, default_tagged_destructor_set,
4587 default_tagless_destructor_set, default_tagged_printer_set,
4588 default_tagless_printer_set): Update.
4589 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
4590 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
4592 (symbol_print): Use SYMBOL_CODE_PRINT.
4594 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4596 Use the new code_props interface for rule actions.
4597 * src/symlist.h (symbol_list): Replace action, action_location, and
4598 used members with a code_props action_props member.
4599 * src/reader.c (symbol_should_be_used, grammar_rule_check,
4600 grammar_midrule_action, grammar_current_rule_merge_set,
4601 grammar_current_rule_symbol_append, packgram): Update.
4602 * src/scan-code.h (translate_rule_action): Remove, no longer used.
4603 * src/scan-code.l (handle_action_dollar): Update.
4604 (translate_rule_action): Remove, no longer used.
4605 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
4607 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4609 Use the new code_props interface in parse-gram.y.
4610 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
4611 Update all uses of translate_* functions to use the new code_props
4612 interface and to use gram_scanner_last_string_free and
4613 code_scanner_last_string_free where possible.
4614 (grammar_declaration): symbol_list_destructor_set and
4615 symbol_list_printer_set now perform the translation, so don't do it
4616 here. Use gram_scanner_last_string_free where possible.
4617 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
4618 translate_code): Remove, no longer used.
4619 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
4620 symbol_list_printer_set): Perform code translation here rather than
4621 depending on the caller to do so.
4623 * src/symlist.h (struct symbol_list): Correct some documentation typos.
4624 * src/scan-gram.h (gram_last_string): Remove declaration.
4625 * src/scan-gram.l (last_string): Declare it static.
4627 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4629 Encapsulate code properties and related functionality for the various
4630 destructors, printers, and actions into a code_props structure and
4631 interface. This patch merely implements code_props in scan-code.h and
4632 scan-code.l. Future patches will rewrite other modules to use it.
4633 Discussed starting at
4634 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
4635 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
4636 consistently initialize const structs that have an empty location
4638 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
4639 to ensure consistency.
4640 * src/scan-code.h (code_props): New structure.
4641 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
4642 function, macro, and const global variable for initializing a
4643 code_props with no code.
4644 (code_props_plain_init, code_props_symbol_action_init,
4645 code_props_rule_action_init, code_props_translate_code): The rest of
4646 the new code_props functional interface. Among other things, the init
4647 functions set the code_props kind field so that
4648 code_props_translate_code will know whether to behave like
4649 translate_symbol_action, translate_rule_action, or translate_code.
4650 These old translate functions must remain until all other modules are
4651 updated to use the new code_props interface.
4652 (code_scanner_last_string_free): New function similar to
4653 gram_scanner_last_string_free.
4654 (code_scanner_free): Add documentation.
4655 * src/scan-code.l: Implement the new interface.
4656 (code_lex): Make it static, add a code_props* argument, and remove the
4658 (last_string): New static global similar to the one in scan-gram.l.
4659 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
4661 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
4662 code_props since Bison may one day use this information for destructors
4664 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
4665 (handle_action_dollar): Use symbol_list_n_get and set used flag
4666 directly since symbol_list_n_used_set is removed.
4667 (translate_action): Add a code_props* argument and remove the rule,
4668 action, and location arguments. Pass the code_props* on to code_lex.
4669 (translate_rule_action, translate_symbol_action, translate_code):
4670 Rewrite as wrappers around the new code_props interface.
4671 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
4672 it would eventually need to break the encapsulation of code_props.
4674 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4676 * etc/.cvsignore: New.
4678 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4680 Add maintainer-push-check to run maintainer-check using push parsing in
4681 place of pull parsing where available.
4682 * Makefile.am (maintainer-push-check): New.
4683 * data/bison.m4 (b4_use_push_for_pull_if): New.
4684 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
4685 appropriately based on their existing values.
4686 (yypush_parse): Don't print push-parser-specific diagnostics if push
4687 parsing is being used in place of pull parsing.
4688 * data/yacc.c: If push parsing should replace pull parsing, redirect to
4690 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
4691 variable, and insert b4_use_push_for_pull_flag into muscles.
4692 * tests/Makefile.am (maintainer-push-check): New.
4694 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4696 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
4697 (whether successful or failed) so that yypush_parse can be invoked
4698 again to start a new parse using the same yypstate.
4699 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
4700 check multiple yypull_parse invocations on the same yypstate. For pull
4701 mode, extend to check multiple yyparse invocations.
4702 (Exploding the Stack Size with Alloca): Extend to try with
4704 (Exploding the Stack Size with Malloc): Likewise.
4706 * tests/calc.at (Simple LALR Calculator): Don't specify
4707 %skeleton "push.c" since %push-pull-parser implies that now.
4708 * tests/headers.at (export YYLTYPE): Don't check for the push
4709 declarations. Otherwise, this test case can't be used to see if push
4710 mode can truly emulate pull mode.
4711 * tests/input.at (Torturing the Scanner): Likewise.
4712 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
4713 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
4714 AT_YACC_IF, which now includes the case of push mode since %skeleton
4715 need not be used for push mode. This will be more intuitive once
4716 push.c is renamed to yacc.c.
4718 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4720 For push mode, convert yyparse from a macro to a function, invoke yylex
4721 instead of passing a yylexp argument to yypull_parse, and don't
4722 generate yypull_parse or yyparse unless %push-pull-parser is declared.
4723 Discussed starting at
4724 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
4725 * data/bison.m4 (b4_pull_if): New.
4726 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
4727 * data/push.c: Improve M4 quoting a little.
4728 (b4_generate_macro_args, b4_parenthesize): Remove.
4729 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
4730 any time a pull parser is requested.
4731 Don't #define this as a wrapper around yypull_parse. Instead, when
4732 both push and pull are requested, make it a function that does that
4734 (yypull_parse): If there's a b4_prefix, #define this to
4735 b4_prefix[pull_parse] when both push and pull are requested.
4736 Don't define this as a function unless both push and pull are
4738 Remove the yylexp argument and hard-code yylex invocation instead.
4739 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
4741 * src/getargs.c (pull_parser): New global initialized to true.
4742 * getargs.h (pull_parser): extern it.
4743 * src/output.c (prepare): Insert pull_flag muscle.
4744 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
4745 (prologue_declaration): Set both push_parser and pull_parser = true for
4746 %push-pull-parser. Set push_parser = true and pull_parser = false for
4748 * src/scan-gram.l: Don't accept %push_parser as an alternative to
4749 %push-parser since there's no backward-compatibility concern here.
4750 Scan %push-pull-parser.
4751 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
4752 instead of %push-parser.
4753 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
4754 prototype it in the module that calls yyparse.
4755 * tests/input.at (Torturing the Scanner): Likewise.
4756 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
4758 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
4760 Update etc/bench.pl. Optimize push mode a little (the yyn change
4761 deserves most of the credit).
4762 * Makefile.am (SUBDIRS): Add etc subdirectory.
4763 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
4764 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
4765 yytoken, yyval, and yyloc declarations to...
4766 (yyparse or yypush_parse): ... here to improve performance. For
4767 yypush_parse invocations after the first, be sure to assign yyn its old
4769 (yypstate_new): Don't bother initializing the yyresult field since the
4770 initial value isn't used.
4771 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
4772 remove the #define that, in push mode, set it to yyps->NAME.
4773 * etc/Makefile.am: New.
4774 * etc/bench.pl: Remove and build it instead from...
4775 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
4776 "tests/bison" from the build directory by default rather than just
4777 invoking "bison" from $PATH.
4778 (calc_grammar): Update push parser code: don't declare yylval globally,
4779 don't define yyparse_wrapper, and don't #define yyparse.
4780 (bench_grammar): Update to check all working combinations of yacc.c,
4781 push.c, impure, pure, pull, and push.
4783 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4785 For push mode, add pull wrappers around yypush_parse.
4786 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
4787 (yypull_parse): New function wrapping yypush_parse.
4788 (yyparse): New #define wrapping yypull_parse.
4789 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
4791 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
4792 prototype yylex in the module that calls yyparse, and don't prototype
4793 yyparse there. Otherwise, the yyparse expansion won't compile.
4794 * tests/input.at (Torturing the Scanner): Likewise.
4796 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4798 Enable push parsers to operate in impure mode. Thus, %push-parser no
4799 longer implies %pure-parser. The point of this change is to move
4800 towards being able to test the push parser code by running the entire
4801 test suite as if %push-parser had been declared.
4802 * data/push.c (yypush_parse): For impure mode, remove the
4803 yypushed_char, yypushed_val, and yypushed_loc arguments.
4804 Instead, declare these as local variables initialized to the global
4805 yychar, yylval, and yylloc.
4806 For the first yypush_parse invocation only, restore the initial values
4807 of these global variables when it's time to read a token since they
4808 have been overwritten.
4809 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
4811 * tests/calc.at (Simple LALR(1) Calculator): Always declare
4812 %pure-parser along with %push-parser since this test case was designed
4813 for pure push parsers.
4814 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
4815 (AT_YACC_OR_PUSH_IF): New.
4816 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
4817 add a note that it's still wrong for some cases (as it has been for a
4819 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
4820 %push-parser no longer implies %pure-parser.
4822 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4824 Remove some unnecessary differences between the pull parser code and
4825 the push parser code. This patch enables yynerrs in push mode.
4826 * data/push.c: Reformat M4 a little.
4827 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
4828 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
4829 because push mode is on. Instead, if pure mode is on, move yynerrs
4831 (b4_declare_parser_state_variables): ... here.
4832 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
4833 to yyps->NAME so it can be used in yypush_parse.
4834 (yypush_parse): Don't omit uses of yynerrs in push mode.
4836 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4838 Fix bug such that the first pushed token's value and location are
4839 sometimes overwritten (sometimes by %initial-action) before being used.
4840 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
4841 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
4842 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
4843 more closely mimic the pull parser logic.
4844 Don't copy the pushed token to yychar, yylval, and yylloc until it's
4845 time to read a token, which is after any initialization of yylval and
4847 (gottoken): Rename label to...
4848 (yyread_pushed_token): ... for clarity and to avoid infringing on the
4851 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4853 Rearrange initialization of the parser state variables so that the
4854 skeleton doesn't have to have a copy for pull mode and another for push
4855 mode. This patch also fixes at least a bug such that yylloc was not
4856 initialized (with b4_location_initial_line and
4857 b4_location_initial_column) upon calling yypush_parse. However, that
4858 initialization now overwrites the first token's location;
4859 %initial-action assigning @$ already did the same thing, and both bugs
4860 will be fixed in a later patch.
4861 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
4862 (b4_declare_parser_state_variables): Remove initialization of yytoken,
4863 yyss, yyvs, yyls, and yystacksize.
4864 (yypstate_new): Remove initialization of some yypstate fields: yystate,
4865 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
4867 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
4868 yyps->NAME so it can be used in yypush_parse.
4869 (yyparse or yypush_parse): For yypush_parse, don't print the
4870 "Starting parse" diagnostic for invocations after the first.
4871 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
4872 yypush_parse, only do it for the first invocation.
4873 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
4874 initialization to occur in yypush_parse but only on the first
4877 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4879 * data/push.c: Add CPP guards around push parser declarations in both
4880 the header and the code file.
4881 In the code file, move the push parser declarations to the same place
4882 they appear in the header file.
4883 Clean up the M4 some, especially the inconsistent underquoting in
4884 some b4_c_function_def and b4_c_function_decl uses.
4886 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4888 Encapsulate the push parser state variables into an M4 macro so the
4889 push skeleton doesn't have to list them again for pull mode's yyparse.
4890 For push mode, remove yypush_parse's local equivalents of these
4891 variables to eliminate unnecessary copying between the two sets at
4892 run-time. This patch also fixes at least a bug related to multiple
4893 %initial-action invocations in push mode.
4894 * data/push.c (b4_declare_parser_variables): Rename to...
4895 (b4_declare_scanner_communication_variables): ... this for clarity and
4897 (b4_declare_yyparse_variables): Remove and move its contents to the one
4898 spot where it was invoked.
4899 (b4_declare_parser_state_variables): New macro containing the parser
4900 state variables required by push mode.
4901 (struct yypstate): Replace all fields but yynew with
4902 b4_declare_parser_state_variables.
4903 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
4904 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
4905 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
4906 (yyparse or yypush_parse): For yyparse in pull mode, replace local
4907 parser state variable declarations with
4908 b4_declare_parser_state_variables.
4909 Don't initialize parser state variables when calling yypush_parse since
4910 yypstate_new already does that.
4911 Invoke the user's initial action only upon the first yypush_parse
4913 Remove all code that copies between the local parser state variables
4916 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4918 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
4919 prevent a name collision in a future patch where these names will
4920 sometimes be #define'd.
4921 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
4922 since it no longer has the same name as the existing argument.
4923 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
4925 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
4926 and Joel E. Denny <jdenny@ces.clemson.edu>
4928 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
4929 that the argument is case-insensitive, and there's no `=' here.
4930 For the %skeleton entry, mention that %language is better.
4931 (Bison Options): Likewise for --language and --skeleton. Move the
4932 --skeleton entry so that the `Tuning the parser' section is sorted
4933 alphabetically on long options.
4934 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
4935 %language directive in detail here; cross-reference the %language
4936 documentation instead.
4937 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
4938 `%require "2.3b"' so that the example is always up-to-date.
4939 (Table of Symbols): Add entries for %language and %skeleton.
4940 * examples/extexi (normalize): Instead of replacing every %require
4941 argument with the current Bison version, just substitute for
4942 `@value{VERSION}'. This guarantees that we're testing what actually
4943 appears in the documentation.
4944 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
4945 rather than `@VERSION@'.
4947 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4949 * NEWS: Reword the %language news a bit, and put it earlier.
4951 * src/getargs.c (skeleton_arg): Last arg is now location const *.
4952 Rewrite to simplify the logic.
4953 (language_argmatch): Likewise.
4954 (program_name): We now own this var.
4955 * src/getargs.h (struct bison_language): Use char[] rather than
4958 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
4960 * src/complain.c (program_name): Remove decl; no longer needed.
4961 * src/main.c (program_name): Remove; now belongs to getargs.
4963 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
4965 * NEWS: Document %language.
4967 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
4969 * data/c-skel.m4, data/c++-skel.m4: New files.
4970 * data/glr.c: Complain on push parsers.
4972 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
4974 (Decl Summary): Document %language and %skeleton.
4975 (Command line): Document -L.
4977 * examples/extexi: Rewrite %require directive.
4978 * examples/calc++/Makefile.am: Pass VERSION to extexi.
4980 * src/files.c (compute_exts_from_gc): Look in language structure
4982 (compute_file_name_parts): Check whether .tab should be added.
4983 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
4984 (language, skeleton_arg, language_argmatch): New.
4985 (long_options): Add --language.
4986 (getargs): Use skeleton_arg, add -L/--language.
4987 * src/getargs.h: Include location.h.
4988 (struct bison_language, language, skeleton_arg, language_argmatch): New.
4989 * src/output.c (prepare): Pick default skeleton from struct language.
4990 Don't dispatch C skeletons here.
4991 * src/parse-gram.y (PERCENT_LANGUAGE): New.
4992 (prologue_declaration): Add "%language" rule, use skeleton_arg.
4993 * src/scan-gram.l ("%language"): New rule.
4995 * tests/calc.at: Test %skeleton and %language.
4996 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
4997 (AT_GLR_IF): Look for %skeleton "glr.cc".
4998 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
4999 (AT_YACC_IF): Reject %language.
5001 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5003 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
5004 since it wasn't used; only the typedef name 'semantic_type' is needed.
5005 Also, omit trailing white space.
5007 * bootstrap: Sync from coreutils.
5008 (gnulib_extra_files): Add build-aux/announce.gen.
5009 (slurp): Adjust .gitignore files like .cvsignore files.
5010 * build-aux/announce-gen: Remove from CVS, since bootstrap
5013 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
5015 Make %push-parser imply %pure-parser. This fixes several bugs; see
5016 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
5017 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
5019 * data/push.c: Don't bother testing b4_push_if when deciding whether
5020 to expand b4_declare_parser_variables globally.
5021 (yypush_parse): Likewise in here.
5023 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
5024 (yy_reduce_print): Reformat M4 for readability.
5026 2006-12-15 Bob Rossi <bob@brasko.net>
5027 and Joel Denny <jdenny@ces.clemson.edu>
5029 * data/push.c (yypstate): Add typedef, and update all uses of
5030 struct yypstate to just yypstate.
5031 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
5033 2006-12-14 Bob Rossi <bob@brasko.net>
5035 * data/push.c (yypush_parse): Declare prototype regardless of
5038 2006-12-14 Bob Rossi <bob@brasko.net>
5040 * data/push.c (yyparse): Remove the prototype and the #define when in
5043 2006-12-13 Bob Rossi <bob@brasko.net>
5045 * data/push.c (yypstate_init): Rename to...
5046 (yypstate_new): ... this and use b4_c_function_def.
5047 (yypstate_delete): New.
5048 (yypush_parse): Change parameters yynval and yynlloc to be const.
5049 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
5050 yypstate_delete functions.
5052 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
5054 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
5055 strange test case titles. Reported by Bob Rossi.
5057 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
5059 * TODO: Add pointer to Sylvain Schmitz's work on static detection
5060 of potential ambiguities in GLR grammers.
5062 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
5064 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
5065 `bison ', use m4_index instead of m4_substr since chopping up a string
5066 containing M4-special characters causes problems here.
5068 Fix a couple of bugs related to special characters in user-specified
5069 file names, and make it easier for skeletons to compute output file
5070 names with the same file name prefix as Bison-computed output file
5072 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
5073 b4_parser_file_name and b4_spec_defines_file instead of
5074 @output_parser_name@ and @output_header_name@, which are now redundant.
5075 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
5076 b4_parser_file_name, b4_spec_defines_file, and the new
5077 @basename(FILENAME@) instead of @output_parser_name@ and
5078 @output_header_name@, which inappropriately escaped the file names as
5080 * src/files.c (all_but_ext): Remove static qualifier.
5081 (compute_output_file_names): Move `free (all_but_ext)' to...
5082 (output_file_names_free): ... here since all_but_ext is needed later.
5083 * src/files.h (all_but_ext): Extern.
5084 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
5085 exactly what MUSCLE_INSERT_STRING used to do.
5086 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
5087 characters are escaped properly.
5088 * src/output.c (prepare): Define muscle file_name_all_but_ext as
5090 For pkgdatadir muscle, maintain previous functionality by using
5091 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
5092 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
5093 digraphs would never be expanded. Hopefully no one has M4-special
5094 characters in his Bison installation path.
5095 * src/scan-skel.l: Don't parse @output_header_name@ and
5096 @output_parser_name@ anymore since they're now redundant.
5097 In @output, use decode_at_digraphs.
5098 Parse a new @basename command that invokes last_component.
5099 (decode_at_digraphs): New.
5100 (BASE_QPUTS): Remove unused.
5101 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
5102 (Output file name): New tests.
5104 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
5106 Warn about output files that are generated by the skeletons and that
5107 conflict with other output files.
5108 * data/glr.c: Don't generate the header file here when glr.cc does.
5109 * src/files.c (file_names, file_names_count): New static globals.
5110 (compute_output_file_names): Invoke output_file_name_check for files
5111 not generated by the skeletons and remove existing checks.
5112 (output_file_name_check): New function that warns about conflicting
5114 (output_file_names_free): Free file_names.
5115 * src/files.h (output_file_name_check): Declare.
5116 * src/scan-skel.l: Invoke output_file_name_check for files generated by
5118 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
5119 (Conflicting output files): New tests.
5121 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5123 * doc/bison.texinfo: Fix a couple of typos.
5125 2006-12-08 Bob Rossi <bob@brasko.net>
5127 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
5129 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
5131 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
5132 (yypush_parse): Rename yypvars argument to yyps and remove redundant
5134 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
5135 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
5137 2006-12-07 Bob Rossi <bob@brasko.net>
5138 and Joel Denny <jdenny@ces.clemson.edu>
5140 * data/push.c (yypvarsinit): Change return type from void* to struct
5141 yypvars*. No longer cast to void* on return.
5142 (struct yypvars): Remove yylen since it need not be remembered between
5143 yypushparse invocations.
5144 (yypushparse): Don't copy between yylen and pv->yylen.
5146 2006-12-05 Bob Rossi <bob@brasko.net>
5148 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
5149 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
5150 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
5151 (struct yypvars): Remove b4_declare_parser_variables.
5152 (yypvarsinit): Remove init code for removed variables.
5153 (global scope): Do not declare b4_declare_parser_variables if
5155 (yypushparse): Add b4_declare_parser_variables.
5156 Init new local variables, and remove init code for removed
5159 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
5160 and yyparse for other modes.
5161 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
5162 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
5163 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
5164 (AT_PURE_LEX_IF): True if pure or push parser.
5166 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>

5194 occurrence of each of %file-prefix and %output. Add check for %defines
5196 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
5197 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
5198 Remove the `=' from %output.
5200 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
5202 Don't escape $ in test case titles since Autoconf 2.61 now does that

5227 Unused values with default %destructor): Update.
5229 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>

5235 won't take a nonterminal.
5237 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
5239 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
5240 it was double-quoted.
5241 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
5242 grammar is maintained with Bison's highest standards.
5243 * src/getargs.c: Fix some typos in Doxygen comments.
5245 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
5247 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
5248 later. Reported by Paul Eggert in
5249 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
5250 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
5251 * src/scan-code.l (translate_action): Don't bother invoking
5252 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
5253 (code_scanner_free): Instead of invoking
5254 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
5256 * src/scan-gram.l (gram_scanner_free): Likewise.
5257 * src/scan-skel.l (scan_skel): Likewise.
5259 2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
5261 * src/files.c (tr): Change return type to void.
5262 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
5263 has been called previously for the same key.
5264 (muscle_find): Return storage instead of value so that
5265 --enable-gcc-warnings doesn't produce warnings that the return discards
5266 const. aver that the value and storage are the same since storage
5267 could potentially be NULL when value is not.
5268 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
5271 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
5273 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
5274 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
5275 us a slightly cleaner distribution, and also works.
5276 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent

5280 and Paul Eggert <eggert@cs.ucla.edu>
5282 Don't let Bison leak memory except when it complains.
5283 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
5284 (spec_defines_file, dir_prefix): Now char *, not const char *,
5285 since they are freed.
5286 * src/files.c: Likewise.
5287 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
5289 (tr): Now operates in-place. All uses changed.
5290 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
5292 (compute_file_name_parts, compute_output_file_names): Don't store
5293 read-only data in variables that will be freed.
5294 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
5295 src_extension, and header_extension.
5296 (output_file_names_free): New public function to free
5297 spec_verbose_file, spec_graph_file, spec_defines_file,
5298 parser_file_name, and dir_prefix.
5299 * src/getargs.c (getargs): Don't store read-only data in variables that
5301 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
5302 (which previously existed but was unused), and quotearg_free.
5303 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
5304 * src/muscle_tab.c: Likewise.
5305 (muscle_entry): Make the value char const *,
5306 and add a new storage member that is char * and can be freed.
5307 (muscle_entry_free): New private function.
5308 (muscle_init): Use it instead of free.
5309 (muscle_insert, muscle_grow): Update and use new storage member.
5310 (muscle_code_grow): Free the string passed to muscle_grow
5311 since it's not needed anymore.
5312 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
5313 add a new `char *code' member.
5314 ("{...}"): Declare semantic type as code.
5315 * src/scan-code.h (translate_rule_action):
5316 (translate_symbol_action, translate_code, translate_action): Return
5317 `char const *' rather than `char *' since external code should not free
5319 * src/scan-code.l: Likewise.
5320 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
5321 which is "{...}" in the parser.
5322 * tests/Makefile.am (maintainer-check-valgrind): Set
5323 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
5325 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
5327 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
5328 expecting a non-zero exit status sets --leak-check=summary and
5329 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
5330 this case, and we don't want to hear about it.
5332 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
5334 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
5335 instead of from the template, to simplify configuration a bit.

5351 declarations): Run tests with and without --warnings=midrule-values.
5353 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
5354 than LIST_FREE directly.
5356 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

5375 empty subargument list. For example: `bison --warnings= parser.y'.
5377 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
5379 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
5380 the parser header file so that gcc doesn't warn.
5382 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>

5432 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
5433 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
5434 like $@n instead of just @n so that the default %destructor/%printer
5435 logic doesn't see them as user-defined symbols.
5436 (symbol_is_dummy): Check for both forms of the name.
5437 * src/reader.c (packgram): Remove the `$' from each midrule symbol
5438 name for which the midrule value is referenced in any action.

5449 (packgram): Before invoking grammar_rule_check on any rule, make sure
5450 all actions have already been scanned in order to set `used' flags.
5451 Otherwise, checking that a midrule's $$ is set will not always work
5452 properly because the midrule check must forward-reference the midrule's

5464 to show how these directives may be viewed as code labels.
5466 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
5468 Similar to the recently removed %before-header, add %code-top as the
5469 alternative to the pre-prologue. Mentioned at

5536 Fix testsuite for ./configure --enable-gcc-warnings:
5537 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.

5581 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
5582 variable was sometimes used without being initialized. This
5583 messed up the installation of the INSTALL file in some cases.
5585 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
5587 * bootstrap (usage, main program, symlink_to_gnulib): Add option
5588 --copy. Inspired by a suggestion from Bruno Haible.
5590 2006-10-03 Jim Meyering <jim@meyering.net>
5592 * bootstrap: Undo last change to this file, since now gnulib-tool
5593 sticks with the automake default in generating dependencies.
5595 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
5597 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

5703 when all of the sources in a directory come from gnulib.
5704 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake

5780 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
5781 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
5782 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
5783 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
5784 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
5785 * src/system.h: Include inttypes.h unconditionally, now that we
5786 use the inttypes module. Don't bother to include stdint.h, since
5787 inttypes.h now does that for us.
5788 (LOCALEDIR): Remove, now that we use the configmake module.
5789 * src/getargs.c: Include configmake.h.
5790 * src/main.c: Likewise.
5791 * src/output.c: Likewise.
5792 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
5793 not from $abs_top_builddir, since config.h moved.
5796 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
5797 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
5799 * src/parse-gram.y (symbol_declaration): Don't put statements
5800 before declarations; it's not portable to C89.
5801 * src/scan-code.l (handle_action_at): Likewise.
5803 * src/scan-code.l: Always initialize braces_level; the old code
5804 left it uninitialized and therefore had undefined behavior.
5806 Don't attempt to redefine 'assert', since it runs afoul of
5807 systems where standard headers (mistakenly) include <assert.h>.
5808 Instead, define and use our own alternative, called 'aver'.
5809 * src/reader.c: Don't include assert.h, since we no longer
5811 * src/scan-code.l: Likewise.
5812 * src/system.h (assert): Remove, replacing with....
5813 (aver): New function, taking a bool arg. All uses changed.
5814 * src/tables.c (pack_vector): Ensure that aver arg is bool,
5815 not merely an integer.
5817 2006-09-15 Bob Rossi <bob@brasko.net>
5819 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
5820 * data/c.m4 (YYPUSH): New.
5821 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
5822 * src/getargs.c (push_parser): New var.
5823 * src/getargs.h (push_parser): New declaration.
5824 * src/output.c (prepare): Add macro insertion of `push_flag'.
5825 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
5826 (prologue_declaration): Parse %push-parser.
5827 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
5828 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
5829 list of removed lines from the traces observed.
5830 (AT_CHECK_CALC_LALR): Added push parser tests.
5832 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
5834 * NEWS: Version 2.3a.
5835 * configure.ac (AC_INIT): Likewise.
5837 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
5838 "#define YYSTYPE int" that caused "make maintainer-check" to fail
5839 due to header ordering dependencies. I don't know why the #define
5842 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
5843 runtime cost when YYDEBUG is not defined, and so that some tests
5844 that used to fail now work. Problem and initial suggestion by
5846 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
5847 * data/glr.cc (b4_parser_class_name):
5848 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
5849 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
5850 (yydebug_) [YYDEBUG]: New member.
5851 (yycdebug_): Now defined only if YYDEBUG.
5852 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
5853 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
5854 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
5856 (debug_stream, set_debug_stream, debug_level, set_debug_level):
5857 Define only if YYDEBUG.
5858 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
5860 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
5861 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
5862 AT_CHECK_CALC_GLR_CC that are working now.
5864 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
5866 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
5867 We don't need them in glr.cc, and glr.c defines them.
5868 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
5869 assumes that defining it to anything is the same as defining
5870 it to 1. Problem reported by Paolo Bonzini.
5872 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
5874 * data/c.m4 (b4_null, b4_case): Define.
5875 * src/output.c (prepare_symbols): Use b4_null.
5876 (user_actions_output): Use b4_case.
5878 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
5880 * data/glr.c (b4_shared_declarations): Put start-header first,
5881 before any #includes that we generate, so that feature-test
5882 macros work. Problem reported by Michael Deutschmann in
5883 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
5884 * data/lalr1.cc: Likewise.
5885 * doc/bison.texinfo (Prologue): Document that feature-test macros
5886 should be defined before any Bison declarations.
5887 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
5888 that depend on location.hh after, not before, Bison decls, since
5889 we now include location.hh after the first user prologue.
5891 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
5892 Sander Brandenburg in
5893 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
5894 Also, fix minor white space and comment issues.
5895 (Prologue): Mention that it's better to define feature-test macros
5896 before Bison declarations. Problem reported by Michael Deutschmann.
5898 * README-cvs: Fix typo: "&" should be "&&". Problem reported
5900 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
5901 This adjusts to recent gnulib changes.
5903 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
5905 Finish implementation of per-type %destructor/%printer. Discussed
5907 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
5909 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
5910 * NEWS (2.3+): Add a description of this feature to the default
5911 %destructor/%printer description.
5912 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
5913 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
5914 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
5915 list node contains a semantic type.
5916 * src/symtab.c, src/symtab.h: Extend with a table that associates
5917 semantic types with their %destructor's and %printer's.
5918 (semantic_type_from_uniqstr, semantic_type_get,
5919 semantic_type_destructor_set, semantic_type_printer_set): New functions
5920 composing the public interface of that table.
5921 (symbol_destructor_get, symbol_destructor_location_get,
5922 symbol_printer_get, symbol_printer_location_get): If there's no
5923 per-symbol %destructor/%printer, look up the per-type before trying
5925 * tests/actions.at (Per-type %printer and %destructor): New test case.
5926 * tests/input.at (Default %printer and %destructor redeclared):
5927 Extend to check that multiple occurrences of %symbol-default in a
5928 single %destructor/%printer declaration is an error.
5929 (Per-type %printer and %destructor redeclared, Unused values with
5930 per-type %destructor): New test cases.
5932 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
5934 Require default %destructor/%printer to be declared using
5935 %symbol-default instead of an empty symbol list, and start working on
5936 new per-type %destructor/%printer. Discussed at
5937 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
5938 * NEWS (2.3+): Add %symbol-default to example.
5939 * bison.texinfo (Freeing Discarded Symbols): Likewise.
5940 (Table of Symbols): Add entry for %symbol-default.
5941 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
5942 (generic_symlist, generic_symlist_item): New nonterminals for creating
5943 a list in which each item is a symbol, semantic type, or
5945 (grammar_declaration): Use generic_symlist in %destructor and %printer
5946 declarations instead of symbols.1 or an empty list.
5947 (symbol_declaration, precedence_declaration, symbols.1): Update actions
5948 for changes to symbol_list.
5949 * src/reader.c: Update for changes to symbol_list.
5950 * src/scan-code.l: Likewise.
5951 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
5952 * src/symlist.c, src/symlist.h: Extend such that a list node may
5953 represent a semantic type or a %symbol-default in addition to just an
5954 ordinary symbol. Add switched functions for setting %destructor's and
5956 * tests/actions.at, tests/input.at: Add %symbol-default to all default
5957 %destructor/%printer declarations.
5959 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
5961 Whether the default %destructor/%printer applies to a particular symbol
5962 isn't a question of whether the user *declares* that symbol (in %token,
5963 for example). It's a question of whether the user by any means
5964 *defines* the symbol at all (by simply using a char token, for
5965 example). $end is defined by Bison whereas any other token with token
5966 number 0 is defined by the user. The error token is always defined by
5967 Bison regardless of whether the user declares it with %token, but we
5968 may one day let the user define error as a nonterminal instead.
5969 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
5970 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
5971 the meaning of "user-defined".
5972 * tests/actions.at (Default %printer and %destructor for user-declared
5973 end token): Rename to...
5974 (Default %printer and %destructor for user-defined end token): ...
5977 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
5978 computation of whether to apply the default, don't maintain a list of
5979 every Bison-defined symbol. Instead, just check for a first character
5980 of '$', which a user symbol cannot have, and check for the error token.
5982 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
5984 Don't apply the default %destructor or %printer to the error token,
5985 $undefined, or $accept. This change fits the general rule that the
5986 default %destructor and %printer are only for user-declared symbols,
5987 and it solves several difficulties that are described in the new test
5989 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
5990 * tests/actions.at (Default %printer and %destructor are not for error
5991 or $undefined, Default %printer and %destructor are not for $accept):
5994 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
5996 Allow %start after the first rule.
5997 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
5998 when parsing the first rule.
5999 (check_and_convert_grammar): Search for it here after all grammar
6000 declarations have been parsed. Skip midrules, which have dummy LHS
6002 * src/symtab.c (symbol_is_dummy): New function.
6003 * src/symtab.h (symbol_is_dummy): Declare it.
6004 * tests/input.at (%start after first rule): New test.
6006 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6008 Redo some of the previous commit: add back the ability to use
6009 non-aliased/undeclared string literals since it might be useful to
6010 those declaring %token-table.
6011 * src/reader.c (check_and_convert_grammar): Undo changes in previous
6012 commit: don't worry about complaints from symbols_pack.
6013 * src/symtab.c (symbol_new, symbol_class_set,
6014 symbol_check_alias_consistency): Undo changes in previous commit: count
6015 each string literal as a new symbol and token, assign it a symbol
6016 number, and don't complain about non-aliased string literals.
6017 (symbols_pack): Since symbol_make_alias still does not decrement symbol
6018 and token counts but does still set aliased tokens to the same number,
6019 symbol_pack_processor now leaves empty slots in the symbols array.
6021 * tests/regression.at (Undeclared string literal): Remove test case
6022 added in previous commit since non-aliased string literals are allowed
6024 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
6025 remove unnecessary string literal declarations.
6026 * tests/sets.at (Firsts): Likewise.
6028 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6030 Don't allow an undeclared string literal, but allow a string literal to
6031 be used before its declaration.
6032 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
6033 symbols_pack complained.
6034 * src/symtab.c (symbol_new): Don't count a string literal as a new
6036 (symbol_class_set): Don't count a string literal as a new token, and
6037 don't assign it a symbol number since symbol_make_alias does that.
6038 (symbol_make_alias): It's not necessary to decrement the symbol and
6039 token counts anymore. Don't assume that an alias declaration occurs
6040 before any uses of the identifier or string, and thus don't assert that
6041 one of them has the highest symbol number so far.
6042 (symbol_check_alias_consistency): Complain if there's a string literal
6043 that wasn't declared as an alias.
6044 (symbols_pack): Bail if symbol_check_alias_consistency failed since
6045 symbol_pack asserts that every token has been assigned a symbol number
6046 although undeclared string literals have not.
6047 * tests/regression.at (String alias declared after use, Undeclared
6048 string literal): New test cases.
6049 (Characters Escapes, Web2c Actions): Declare string literals as
6051 * tests/sets.at (Firsts): Likewise.
6053 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
6055 In the grammar scanner, STRING_FINISH unclosed constructs and return
6056 them to the parser in order to improve error messages.
6057 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
6058 SC_BRACED_CODE, SC_PROLOGUE): Implement.
6059 * tests/input.at (Unclosed constructs): New test case.
6060 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
6063 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
6066 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
6068 Handle string aliases for character tokens correctly.
6069 * src/symtab.c (symbol_user_token_number_set): If the token has an
6070 alias, check and set its alias's user token number instead of its own,
6071 which is set to indicate the alias. Previously, every occurrence of
6072 the character token in the grammar overwrote that alias indicator with
6074 * tests/input.at (String aliases for character tokens): New test.
6076 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
6078 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
6080 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
6082 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
6083 to prevent failures when building on older platforms.
6084 Check for autopoint failure.
6085 Set XGETTEXT_OPTIONS to values that check for C format strings,
6086 so that translators are warned about them (this also helps
6087 prevent core dumps).
6089 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
6090 function, since it simplifies our code a bit.
6092 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
6093 rather than -W, so we don't get bogus warnings about sign comparisons.
6094 Add -Wpointer-arith, since that warning is useful (it reports code
6095 that does not conform to C89 and that some compilers reject).
6096 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
6097 since it's no longer needed.
6099 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
6101 Clean up scanners a bit.
6102 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
6103 definitions so gcc won't warn when obstack_for_string is unused.
6104 * src/scan-code.l: config.h and system.h are already #include'd by
6105 scan-code-c.c, so get rid of them here.
6106 * src/scan-gram.l: Likewise.
6107 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
6108 definitions rather than duplicating the rest of it.
6109 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
6111 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
6113 Suppress signed/unsigned comparison warnings for yycheck.
6114 * data/c.m4 (b4_safest_int_type): New macro.
6115 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
6116 a signed int type, cast it to b4_safest_int_type first.
6117 * data/yacc.c: Likewise.
6118 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
6121 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
6123 * doc/bison.texinfo: Fix some typos.
6125 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
6127 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
6128 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
6130 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
6131 the latest gnulib does this a different way.
6132 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
6133 translation was patched, so stop omitting it.
6135 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6137 Enable declaration of default %printer/%destructor. Make the parser
6138 use these for all user-declared grammar symbols for which the user does
6139 not declare a specific %printer/%destructor. Thus, the parser uses it
6140 for token 0 if the user declares it but not if Bison generates it as
6141 $end. Discussed starting at
6142 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
6143 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
6145 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
6146 * NEWS (2.3+): Mention.
6147 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
6148 declare a %destructor for a mid-rule's semantic value. It's just
6149 impossible to declare one specific to it.
6150 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
6151 code. Describe default %destructor form.
6152 * src/parse-gram.y (grammar_declaration): Parse default
6153 %printer/%destructor declarations.
6154 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
6155 and symbol_destructor_location_get rather than accessing the destructor
6156 and destructor_location members of struct symbol.
6157 (symbol_printers_output): Likewise but for %printer's.
6158 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
6160 * src/symtab.c (default_destructor, default_destructor_location,
6161 default_printer, default_printer_location): New static global
6162 variables to record the default %destructor and %printer.
6163 (symbol_destructor_get, symbol_destructor_location_get,
6164 symbol_printer_get, symbol_printer_location_get): New functions to
6165 compute the appropriate %destructor and %printer for a symbol.
6166 (default_destructor_set, default_printer_set): New functions to set the
6167 default %destructor and %printer.
6168 * src/symtab.h: Prototype all those new functions.
6169 * tests/actions.at (Default %printer and %destructor): New test to
6170 check that the right %printer and %destructor are called, that they're
6171 not called for $end, and that $$ and @$ work correctly.
6172 (Default %printer and %destructor for user-declared end token): New
6173 test to check that the default %printer and %destructor are called for
6174 a user-declared end token.
6175 * tests/input.at (Default %printer and %destructor redeclared, Unused
6176 values with default %destructor): New tests to check related grammar
6177 warnings and errors.
6179 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6181 Clean up handling of %destructor for the end token (token 0).
6182 Discussed starting at
6183 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
6185 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
6187 Make the skeletons consistent in how they pop the end token and invoke
6189 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
6190 state, which has token number 0, since this would invoke the
6191 %destructor for the end token.
6192 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
6193 until after shifting the end token, or else it won't be popped.
6194 * data/yacc.c (yyparse): Likewise.
6196 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
6197 it's the end token. Upon termination, destroy an unshifted lookahead
6198 even when it's the end token.
6199 * data/lalr1.cc (yy::parser::parse): Likewise.
6200 * data/yacc.c (yyparse): Likewise.
6202 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
6203 value warnings for the end token when the user gives the end token a
6206 * tests/actions.at (Printers and Destructors): Test all the above.
6208 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
6210 Update to latest gnulib and gettext versions.
6211 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
6213 (gnulib_files): Add m4/warning.m4. Don't worry about files
6214 overwritten by autopoint.
6215 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
6216 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
6218 Don't use autoreconf; instead, invoke autopoint etc. by hand,
6219 so that we can remove the intl files at a better time.
6220 (intl_files_to_remove): Remove aclocal.m4, since it gets
6221 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
6222 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
6223 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
6224 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
6225 Remove datarootdir hack; no longer needed.
6226 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
6227 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
6228 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
6230 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
6231 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
6233 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
6235 * bootstrap: Adjust to today's change to gnulib-tool by invoking
6236 it with --assume-autoconf='latest-stable'.
6238 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
6240 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
6241 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
6243 * src/muscle_tab.h (muscle_grow): Replace the header comments with
6244 those from muscle_tab.c since the old ones are misleading.
6246 2006-07-13 Akim Demaille <akim@epita.fr>
6248 Support %define "KEY" {VALUE}.
6249 * src/scan-code.h, src/scan-code.l (translate_action)
6250 (translate_rule_action, translate_symbol_action, translate_code):
6251 Return char *, not const char *.
6252 * src/parse-gram.y (declaration): Rename as...
6253 (prologue_declaration): this.
6254 (string_content): Remove this nonterminal, use STRING.
6255 (braceless, content, content.opt): New nonterminal.
6257 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
6259 * src/scan-gram.l (getargs.h): Don't include it.
6261 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
6263 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
6264 rather than a for-loop that declares a local bool variable. This
6265 should work around a compatibility problem with a Cray x1e C++
6266 compiler reported by Hung Nguyen in
6267 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
6268 The for-loop was introduced in the 2004-11-17 change but I don't
6269 know why it was needed.
6271 2006-07-12 Akim Demaille <akim@epita.fr>
6273 * data/c.m4: Comment changes.
6275 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
6277 * src/complain.c (error_message, ERROR_MESSAGE): New.
6279 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
6280 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
6282 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
6284 * NEWS: Instead of %union, you can define and use your own union type
6285 YYSTYPE if your grammar contains at least one <type> tag.
6286 Your YYSTYPE need not be a macro; it can be a typedef.
6287 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
6288 (Union Decl, Decl Summary): Document this.
6289 * data/glr.c (YYSTYPE): Implement this.
6290 * data/glr.cc (YYSTYPE): Likewise.
6291 * data/lalr1.cc (YYSTYPE): Likewise.
6292 * data/yacc.c (YYSTYPE): Likewise.
6293 * src/output.c (prepare): Output tag_seen_flag.
6294 * src/parse-gram.y (declaration, grammar_declaration):
6295 Use 'union_seen' rather than 'typed' to determine whether
6296 %union has been seen, since grammars can now be typed without
6298 (symbol_declaration, type.opt, symbol_def):
6299 Keep track of whether a tag has been seen.
6300 * src/reader.c (union_seen, tag_seen): New vars.
6302 * src/reader.h (union_seen, tag_seen, typed): Likewise.
6303 * src/scan-code.l (untyped_var_seen): New variable.
6304 (handle_action_dollar): Adjust to above changes.
6305 (handle_action_dollar, handle_action_at):
6306 Improve overflow checking for outlandish numbers.
6307 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
6308 avoid new diagnostics generated by above changes.
6309 * tests/regression.at (YYSTYPE typedef): Add test to check
6310 for type tags without %union.
6312 * src/symlist.c (symbol_list_length): Return int, not unsigned
6313 int, since callers expect int. This may need to get revisited
6314 once we have proper integer overflow checking.
6316 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
6317 object is now static.
6319 * src/getargs.c (flags_argmatch): Return void, not int,
6320 to pacify ./configure --enable-gcc-warnings.
6322 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
6323 since last_string is already defined to FLEX_PREFIX (last_string).
6325 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
6327 Implement --warnings/-W.
6328 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
6330 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
6332 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
6333 (warnings_args, warnings_types): New.
6334 (getargs, short_options, long_options): Accept -W/--warnings.
6335 Sort the options by alphabetical order, upper case letter right
6336 before its lower case.
6338 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
6340 Change %merge result type clash warnings to errors. Discussed at
6341 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
6342 * src/reader.c (record_merge_function_type): Use complain_at.
6343 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6344 declared later): Update test case results.
6346 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
6348 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
6349 to be in alphabetical order.
6350 (trace_args): Spelling fixes.
6352 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
6354 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
6355 so they don't collide with user-defined macros.
6356 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
6357 this was never guaranteed, and now that we're using gnulib stdint,
6358 which defines int_fast16_t to long int, the problem is exposed.
6360 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
6362 * data/c.m4 (b4_basename): Simplify a bit, since we don't
6363 need the full POSIX semantics (and weren't implementing them
6366 Adjust to Autoconf 2.60 and today's gnulib.
6367 * bootstrap (gnulib_modules): Add stdint.
6368 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
6369 no longer copies it.
6370 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
6371 since stdint needs the former and wcwidth (which is now required
6372 by mbswidth) needs the latter.
6373 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
6374 work around a compatibility glitch between gettext 0.14.6 and
6376 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
6377 Do not check for uintptr_t, since new stdint module does the right
6379 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
6380 Add stdint.h, stdint_.h, wcwidth.h.
6381 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
6382 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
6383 stdint.m4, wchar_t.m4, wcwidth.m4.
6384 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
6385 usual order for ../lib/*.h files.
6386 (file_name_split): Use last_component, not base_name, to adjust
6388 * src/parse-gram.h: Include <strverscmp.h> in the usual order
6389 for ../lib/*.h files.
6390 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
6391 Define unconditionally, since we now assume the stdint module.
6392 * src/scan-skel.l: Include <dirname.h>.
6393 (BASE_QPUTS): Use last_component, not base_name.
6394 * src/system.h: Include <unlocked-io.h> in the usual order
6395 for ../lib/*.h files. Include <stdint.h> unconditionally,
6396 since we now use the stdint module.
6397 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
6398 HAVE_UINTPTR_T, since we now use the stdint module.
6399 (base_name): Remove decl, since files now include <dirname.h>
6402 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
6404 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
6406 * data/yacc.c, data/glr.c, data/location.cc: Use them.
6407 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
6409 * tests/calc.at: Adjust.
6411 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
6413 * data/c.m4 (b4_basename): New.
6414 (b4_syncline): Also output the location of its invocation (from
6416 (b4_user_action, b4_define_user_action, b4_user_actions)
6417 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
6418 (b4_user_stype): New.
6419 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
6421 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6423 In the grammar file, the first column is 1 not 0 on the first line as
6424 on every other line.
6425 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
6426 * tests/input.at (Torturing the Scanner): Update output.
6428 * src/scan-gram.l (scanner_cursor): Declare it static.
6430 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6432 In warnings, say "previous declaration" rather than "first
6434 * src/symtab.c (redeclaration): Do that here.
6435 * src/reader.c (record_merge_function_type): In the case of a result
6436 type clash, report the previous declaration rather than the very first
6437 one in the grammar file.
6438 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6439 declared later): Add a third declaration to check this behavior.
6440 * tests/input.at (Incompatible Aliases): Update output.
6442 2006-06-27 Akim Demaille <akim@epita.fr>
6444 * doc/Doxyfile.in: New.
6445 * doc/Makefile.am: Use it.
6446 * src/lalr.h, src/symtab.h: Initial doxygenation.
6448 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6450 Don't miss %merge result type warnings just because the LHS types are
6451 declared after the %merge. This continues the effort of the previous
6453 * src/reader.c (get_merge_function): Don't set the merger type yet.
6454 (record_merge_function_type): New function for setting the merger type
6455 and checking for clashes.
6456 (grammar_current_rule_merge_set): Set the location of the %merge for
6458 (packgram): Invoke record_merge_function_type for each rule now that
6459 all symbol type declarations have been parsed.
6460 * src/reader.h (merger_list.type_declaration_location): New member
6461 storing the location of the first %merge from which the type for this
6462 merging function was derived.
6463 * src/symlist.h (symbol_list.merger_declaration_location): New member
6464 storing the location of a rule's %merge, if any.
6465 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6466 declared later): New test to catch the error fixed by the above patch.
6468 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6470 Get action warnings (grammar_rule_check) right even when symbol
6471 declarations appear after the rules. Discussed at
6472 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
6474 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
6475 Don't mistake the type of $$ in a midrule to be that of its parent
6477 * src/reader.c (grammar_current_rule_end): Don't invoke
6478 grammar_rule_check yet since not all symbol declarations may have been
6480 (grammar_midrule_action): Likewise.
6481 Don't record whether the midrule's $$ has been used yet since actions
6482 haven't been translated yet.
6483 Record the midrule's parent rule and its RHS index within the parent
6485 (grammar_current_rule_action_append): Don't translate the action yet
6486 since not all symbol declarations may have been parsed yet and, thus,
6487 warnings about types for $$, $n, @$, and @n can't be reported yet.
6488 (packgram): Translate the action and invoke grammar_rule_check now that
6489 all symbol declarations have been parsed.
6490 * src/scan-code.l (handle_action_dollar): Now that this is invoked
6491 after parsing the entire grammar file, the symbol list here in the case
6492 of a midrule is actually the midrule's empty RHS, so reference its
6493 parent rule's RHS where necessary.
6494 On the other hand, now that you can already know it's a midrule, you
6495 aren't forced to think $$ has the same type as its parent rule's $$.
6496 (handle_action_at): In the case of a midrule, reference the parent rule
6498 * src/symlist.c (symbol_list_new): Initialize new midrule-related
6500 (symbol_list_length): Now that this is invoked after all rules have
6501 been parsed, a NULL symbol (rather than a NULL symbol list node)
6502 terminates a rule. symbol_list_print already does this correctly.
6503 * src/symlist.h (symbol_list.midrule_parent_rule,
6504 symbol_list.midrule_parent_rhs_index): New members so that midrules can
6505 remember their relationships with their parents.
6506 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
6507 fixed by the above patch.
6508 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
6510 (Unused values): ... this old test case and...
6511 (Unused values before symbol declarations): ... this new test case.
6512 This one is the same as `Unused values' except that all symbol
6513 declarations appear after the rules in order to catch the rest of the
6514 errors fixed by the above patch.
6516 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6519 * src/reader.c (current_rule): Declare it static since it's no longer
6520 used outside this file.
6521 (grammar_current_rule_action_append): Remove redundant arguments from
6522 translate_rule_action invocation.
6523 * src/reader.h (current_rule): Remove this unused extern.
6524 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
6525 * src/scan-code.l (translate_rule_action): Likewise.
6527 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
6529 Clean up yesterday's patch.
6530 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
6532 * src/reader.c (grammar_current_rule_action_append): ... here for
6533 consistency with grammar_current_rule_symbol_append.
6534 * tests/regression.at (Braced code in declaration in rules section):
6535 Make yyerror and yylex static as usual.
6537 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
6539 Fix bug that mistakes braced code in a declaration in the rules section
6540 to be a rule action. Mentioned at
6541 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
6542 * src/scan-gram.l: Move midrule action detection from the start of the
6543 scanning of any braced code to...
6544 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
6545 action. For readability, use $2 and @2 rather than the equivalent
6547 * tests/regression.at (Braced code in declaration in rules section):
6548 New test to catch the error fixed by the above patch.
6550 Work on code readability some.
6551 * src/scan-code.l (current_rule): Get rid of this misleading and
6552 redundant declaration: it's actually extern'ed in reader.h.
6553 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
6554 translate_action): Add a rule argument and use it instead of the global
6556 (translate_rule_action): This already receives current_rule through an
6557 argument, so pass it on to translate_action instead of assigning
6558 current_rule to current_rule.
6559 (translate_symbol_action, translate_code): Pass rule = NULL to
6562 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
6564 Rename %before-definitions to %start-header and %after-definitions to
6565 %end-header. Don't use these declarations to separate pre-prologue
6566 blocks from post-prologue blocks. Add new order-independent
6567 declarations %before-header and %after-header as alternatives to the
6568 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
6569 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
6570 * NEWS (2.3+): Update for these changes.
6571 * data/glr.c (b4_before_definitions): Update to...
6572 (b4_start_header): ... this.
6573 (b4_after_definitions): Update to...
6574 (b4_end_header): ... this.
6575 * data/glr.cc: Likewise.
6576 * data/lalr1.cc: Likewise.
6577 * data/yacc.c: Likewise.
6578 * doc/bison.texinfo (The prologue): Update names, and replace remaining
6579 prologue blocks with %*-header declarations.
6580 (Calc++ Parser): Likewise.
6581 (Decl Summary): Update names.
6582 (Table of Symbols): Update description.
6583 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
6584 (PERCENT_END_HEADER): ... this.
6585 (PERCENT_BEFORE_DEFINITIONS): Update to...
6586 (PERCENT_START_HEADER): ... this.
6587 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6588 (declaration): Update token names and m4 macro names.
6589 When parsing %end-header and %start-header, invoke translate_code
6590 before muscle_code_grow, and no longer set global booleans to remember
6591 whether these declarations have been seen.
6592 Parse new %after-header and %before-header.
6593 * src/reader.c (before_definitions, after_definitions): Remove.
6594 (prologue_augment): Accept a new bool argument to specify whether to
6595 augment the pre-prologue or post-prologue.
6596 * src/reader.h (before_definitions, after_definitions): Remove these
6598 (prologue_augment): Add new bool argument.
6599 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
6600 (PERCENT_END_HEADER): ... this.
6601 (PERCENT_BEFORE_DEFINITIONS): Update to...
6602 (PERCENT_START_HEADER): ... this.
6603 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6604 * tests/actions.at (Printers and Destructors): Update names.
6606 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
6608 Add comparison operators for C++ location classes. Discussed at
6609 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
6610 * data/c++.m4 (b4_define_location_comparison): New boolean %define
6611 declaration indicating whether filename_type has an operator==. If
6612 filename_type is `std::string', it defaults to `1', `0' otherwise.
6613 * data/location.cc: Iff b4_define_location_comparison is `1', add
6614 operator== and operator!= for class position and for class location.
6617 * src/scan-action.l: Remove unused file.
6618 * src/symtab.c (symbol_printer_set): Use printer_location not
6619 destructor_location.
6620 * src/symtab.h (struct symbol): Replace incorrect source comment for
6622 * tests/input.at (Incompatible Aliases): Update output with correct
6625 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
6627 Don't put the pre-prologue in the header file. For the yacc.c code
6628 file and the glr.c header and code files, move the pre-prologue before
6629 the token definitions. Add new %before-definitions and
6630 %after-definitions to declare code that will go in both the header file
6631 and code file. Discussed at
6632 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
6633 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
6635 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
6636 * NEWS (2.3+): Describe these changes.
6637 * data/glr.c (b4_pre_prologue): Move from within to before...
6638 (b4_shared_declarations): ... this.
6639 Add new b4_before_definitions before b4_token_enums.
6640 Add new b4_after_definitions at the end.
6641 * data/glr.cc (b4_pre_prologue): Replace with...
6642 (b4_before_definitions): ... this in the header file.
6643 (b4_after_definitions): New near the end of the header file.
6644 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
6645 code file right before including the header file.
6646 (b4_before_definitions): New in the previous position of
6647 b4_pre_prologue in the header file.
6648 (b4_after_definitions): New near the end of the header file.
6649 * data/yacc.c: Clean up some m4 quoting especially in the header file.
6650 (b4_token_enums_defines): In the code file, move to right before
6651 YYSTYPE for consistency with the header file.
6652 (b4_before_definitions): New right before b4_token_enums_defines in
6653 both the header and code file.
6654 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
6655 header and code file.
6656 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
6657 of prologues for %union dependencies.
6658 (Decl Summary): In %defines description, mention the effect of
6659 %before-definitions and %after-definitions on the header file.
6660 (Calc++ Parser): Forward declare driver in a %before-definitions rather
6661 than in the pre-prologue so that make check succeeds.
6662 (Table of Symbols): Add entries for %before-definitions and
6664 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
6665 %before-definitions.
6666 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
6667 (declaration): Parse those declarations and append to
6668 b4_before_definitions and b4_after_definitions, respectively.
6669 * src/reader.c (before_definitions, after_definitions): New bools to
6670 track whether those declarations have been seen.
6671 (prologue_augment): Add to the post-prologue if %union,
6672 %before-definitions, or %after-definitions has been seen.
6673 * src/reader.h (before_definitions, after_definitions): New extern's.
6674 * src/scan-gram.l: Scan the new declarations.
6675 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
6676 prologue block in a %before-definitions or a %after-definitions based
6677 on whether the %union is declared.
6678 * tests/regression.at (Early token definitions with --yacc, Early token
6679 definitions without --yacc): Move tests for token definitions into the
6680 post-prologue since token names are no longer defined in the
6683 2006-06-20 Akim Demaille <akim@epita.fr>
6685 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
6686 (symbol_get): Use it.
6687 * src/parse-gram.y: Use it.
6689 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
6691 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
6692 build succeeds when configured with --enable-gcc-warnings.
6694 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
6696 * src/parse-gram.y (char_name): New function.
6697 (CHAR, STRING, string_content): For %printer, properly escape.
6698 (ID): Prefer fputs to fprintf.
6699 (id): Reindent to be consistent with other rules.
6700 Properly quote char.
6702 The Translation Project changed its way of publishing translations
6703 to maintainers. I haven't received any responses to my request
6704 for supporting the old way, or for documenting the new way. I
6705 have modified 'bootstrap' to use screen scraping
6706 (in this case, HTML scraping). This is unreliable and inelegant,
6707 but I don't see any better way. Yuck.
6708 * bootstrap (TP_URL, WGET_COMMAND): New vars.
6709 (get_translations): New function, which uses HTML scraping to
6710 deduce locations of latest translations.
6711 Use this function to grab both bison and bison-runtime .po files.
6712 Don't bother priming the pump for the runtime-po domain any more,
6713 as it's now translated better than bison is.
6715 2006-06-19 Akim Demaille <akim@epita.fr>
6717 * src/scan-gram.l: No longer "parse" things after `%union' until
6718 `{'. Rather, return a single "%union" token.
6719 No longer make symbols: return strings, and leave the conversion
6720 to symbols to the parser.
6721 (SC_PRE_CODE, token_type): Remove.
6722 * src/parse-gram.y (%union): New field `character'.
6725 (ID, ID_COLON): Now that the scanner no longer makes them
6726 identifiers, adjust all uses to invoke symbol_get.
6727 (id_colon): New, wraps the conversion from string to symbol.
6728 (%union): Accept a possible union_name.
6729 (symbol): Now can be a char.
6730 * data/c.m4 (b4_union_name): Leave a default value.
6731 * data/glr.c, data/yacc.c: Use it.
6733 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
6735 For associating token numbers with token names for "yacc.c", don't use
6736 #define statements unless `--yacc' is specified; always use enum
6737 yytokentype. Most important discussions start at:
6738 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
6739 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
6741 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
6742 * NEWS (2.3+): Mention.
6743 * data/c.m4 (b4_yacc_if): New.
6744 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
6746 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
6747 on token name definitions.
6748 * src/getargs.c (usage): Capitalize `Yacc' in English.
6749 * src/output.c (prepare): Define b4_yacc_flag.
6750 * tests/regression.at (Early token definitions): Test that tokens names
6751 are defined before the pre-prologue not just before the post-prologue.
6752 Remove this test case and copy to...
6753 (Early token definitions with --yacc): ... this to test #define's.
6754 (Early token definitions without --yacc): ... and this to test enums.
6756 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
6758 * NEWS: Reword the post-2.3 change to not be so optimistic about
6759 removing the old "look-ahead" spelling.
6760 Update previous look-ahead/lookahead change reports.
6761 * REFERENCES: look-ahead -> lookahead (since that's
6762 what he actually wrote).
6763 * doc/refcard.tex: look ahead -> lookahead,
6764 look-ahead -> lookahead
6766 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
6768 For consistency, use `lookahead' instead of `look-ahead' or
6769 `look_ahead'. Discussed starting at

6843 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
6845 * TODO: Add request from Nelson H. F. Beebe to be able to install
6846 Bison without installing the yacc script.
6848 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
6850 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
6851 and yytext if they're already #define'd.
6852 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
6853 * src/scan-code-c.c: ... here.
6854 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include

6859 Get Bison to build again when configured with --enable-gcc-warnings.
6860 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
6862 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
6863 loc argument as it shadows a global.
6864 * src/scan-gram.l: Remove stray comma that prevents boundary_set
6867 * src/.cvsignore: Add scan-code.c.
6869 2006-06-07 Akim Demaille <akim@epita.fr>
6871 * src/scan-gram.l: Move the "add a trailing ; to actions" code
6873 * src/scan-code.l: here.
6874 * tests/input.at (Torturing the Scanner): Fix another location
6877 2006-06-07 Akim Demaille <akim@epita.fr>
6879 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
6881 2006-06-06 Akim Demaille <akim@epita.fr>
6883 Extract the parsing of user actions from the grammar scanner.
6884 As a consequence, the relation between the grammar scanner and
6885 parser is much simpler. We can also split "composite tokens" back
6887 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
6888 * src/scan-gram.l (add_column_width, adjust_location): Move to and
6890 * src/location.h, src/location.c (add_column_width)
6891 (location_compute): these.
6892 Fix the column count: the initial column is 0.
6893 (location_print): Be robust to ending column being 0.
6894 * src/location.h (boundary_set): New.
6895 * src/main.c: Adjust to scanner_free being renamed as
6897 * src/output.c: Include scan-code.h.
6898 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
6900 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
6901 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
6902 which is now, again, a separate token.
6903 Adjust all dependencies.
6904 Whereever actions with $ and @ are used, use translate_code.
6905 (action): Remove this nonterminal which is now useless.
6906 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
6907 (grammar_current_rule_action_append): Use translate_code.
6908 (packgram): Bound check ruleno, itemno, and rule_length.

6914 (YY_DECL): Rename as...
6916 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
6917 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
6918 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
6919 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):

6924 * src/scan-gram.l (rule_length, rule_length_overflow)
6925 (increment_rule_length): Remove.
6926 (last_braced_code_loc): Rename as...
6927 (gram_last_braced_code_loc): this.
6928 Adjust to the changes of the parser.
6929 Move all the handling of $ and @ into...
6930 * src/scan-code.l: here.
6931 * src/scan-gram.l (handle_dollar, handle_at): Remove.

6944 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
6946 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
6947 Use Akim's wording from
6948 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
6950 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
6952 Between Bison releases, manually append `+' to the previous Bison
6953 release number, and use that as a signal to automatically print the
6954 ChangeLog's CVS Id keyword from --version. Discussed starting at
6955 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
6956 * ChangeLog: Add Id header.
6957 * configure.ac (AC_INIT): Append `+' to `2.3'.
6958 * src/.cvsignore: Add revision.c.
6959 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
6960 (BUILT_SOURCES): Add revision.c.
6961 (revision.c): New target rule. This file defines a new global variable
6962 named revision. It initializes it with either the Id from ChangeLog
6963 or, if VERSION doesn't contain `+', with the empty string.
6964 * src/getargs.c (version): Print the value of revision.
6965 * src/revision.h: Extern revision.
6967 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
6969 * NEWS: Version 2.3.
6970 * configure.ac (AC_INIT): Likewise.
6972 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
6974 * data/glr.c (YYRECOVERING): Define to be a function-like macro
6975 with no arguments, not as an object-like macro. This is for
6976 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
6977 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
6978 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
6981 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
6983 * src/getargs.c (usage): Back out yesterday's modification of the
6984 --help output so that we don't have to wait for translation before
6987 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
6989 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
6990 Problem reported by Akim Demaille.
6992 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
6994 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
6996 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
6998 * data/yacc.c (yy_reduce_print): Omit trailing white space in
6999 generated source code. Problem reported by Frans Englich in
7000 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
7002 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
7004 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
7005 shell, not within 'make', so that 'make' by an ordinary builder
7006 (using GNU make) does not worry about configuring gzip. This also
7007 works around a bug reported independently by Keith Thompson and by
7008 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
7009 stderr rather than stdout, messing up the build logs.
7011 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7013 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
7014 to make sure that YYID will never be unused. This fixes a 'make
7015 maintainer-check' failure caused by the recent changes to the 'Trivial
7016 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
7018 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
7020 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7022 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
7023 state before an empty RHS is always resolved here. Only the location
7024 of that state is guaranteed to be resolved, and that's enough. This
7025 fixes the remaining bug reported by Derek M. Jones in
7026 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7027 * tests/glr-regression.at (Uninitialized location when reporting
7028 ambiguity): Test the above case.
7029 Also, the embedded comments in this test case claim it checks the case
7030 of an empty RHS that has inherited the initial location. However, the
7031 corresponding LHS was already resolved, so yyresolveLocations didn't
7032 actually have reason to modify it. Fix this by forcing
7033 nondeterministic operation at the beginning of the parse.
7035 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
7037 * data/c.m4 (b4_yy_symbol_print_generate):
7038 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
7039 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
7040 of the bugs reported today by Derek M Jones in
7041 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7042 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
7043 defined to be a type name without parens or brackets.
7044 (Location Type): Similarly for YYLTYPE.
7045 * tests/regression.at (Trivial grammars): Put in a test for this
7046 bug that will be caught by 'make maintainer-check' (though not,
7047 alas, by 'make check' unless your compiler is picky).
7049 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
7051 * NEWS: Version 2.2.
7052 * configure.ac (AC_INIT): Likewise.
7054 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
7056 * data/glr.c (yyreportTree): Make room in yystates for the state
7057 preceding the RHS. This fixes the segmentation fault reported by Derek
7059 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
7060 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
7061 to the user. Reported for yyreportTree by Derek M. Jones later in the
7063 * THANKS: Add Derek M. Jones.
7064 Update my email address.
7065 Fix typo in Steve Murphy's name.
7067 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
7069 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
7070 checking against YYLAST that caused the parser to miss a potential
7071 alternative in its diagnostic.
7072 Problem reported by Maria Jose Moron Fernandez in
7073 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
7074 * data/lalr1.cc (yysyntax_error_): Likewise.
7075 * data/yacc.c (yysyntax_error): Likewise.
7076 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
7077 tokens, in case we run into an older C compiler.
7078 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
7079 Use them to check for the off-by-one error fixed above.
7081 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
7082 YYSIZE_T, not size_t.
7083 * tests/regression.at (Trivial grammars): New test, to catch
7084 the error fixed by the above patch.
7086 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7088 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
7090 Reported by Steve Murphy.
7092 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7094 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
7095 * data/glr.cc: b4_location_flag is now b4_locations_flag.
7097 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7099 Implement --trace=m4.
7100 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
7101 * src/output.c (output_skeleton): When set, pass -dV to m4.
7103 Factor the handling of flags in m4.
7104 * src/output.c (prepare): Rename the muscle names debug, defines,
7105 error_verbose to debug_flag, defines_flag, error_verbose_flag.
7106 * data/c.m4: Adjust.
7107 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
7108 Use b4_define_flag_if to define other b4_FLAG_if macros.
7109 (b4_location_if): As a consequence, rename as...
7110 (b4_locations_if): this, for consistency.
7111 Adjust all the skeletons.
7113 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7115 * etc/bench.pm: Shorten bench names.
7117 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7119 * src/output.h, src/output.c (error_verbose): Move to...
7120 * src/getargs.h, src/getargs.c: here.
7122 Adjust dependencies.
7124 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
7126 * data/c.m4 (b4_copyright): Put the special exception for Bison
7127 skeletons here, so we don't have to put it in each skeleton. All
7128 uses changed. Suggested by Akim Demaille. Also, wrap the
7129 copyright notice, in case it is longer than 80 columns. Replace
7130 comma by newline after title.
7132 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
7134 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
7135 incompatibility, not a bug. Mention that it wasn't fixed as of
7138 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7140 * examples/extexi: Enforce the precedence of concatenation over
7142 Reported by Tommy Nordgren.
7144 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7146 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
7147 with the member "token".
7148 Reported by Martin Nylin.
7150 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
7152 * data/glr.c: Switch to Bison 2.2 special-exception language in
7153 the copyright notice. Use more-regular format for titles and
7155 * data/glr.cc: Likewise.
7156 * data/location.cc: Likewise.
7157 * data/yacc.cc: Likewise.
7158 * doc/bison.texinfo (Conditions): Document this.
7159 * NEWS: likewise. Upgrade version to 2.2.
7161 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
7163 * data/glr.cc: Remove dead code.
7165 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
7167 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
7168 that variable and the line breaks the bootstrap. Problem reported
7169 by Juan M. Guerrero.
7171 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
7173 * doc/bison.texinfo (Multiple start-symbols): New.
7175 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
7177 * etc/README, etc/bench.pl: New.
7179 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
7181 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
7183 Reported by Mickael Labau.
7184 * tests/input.at (Torturing the Scanner): Test it.
7186 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
7188 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
7189 Problem reported by Bob Rossi.
7191 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
7193 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
7194 and didn't really work.
7195 For the index, use @ifnotinfo, not @iftex.
7196 Minor cleanups of spacing and terminology.
7198 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
7200 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
7201 of AT_NAME_PREFIX when %name-prefix is not used.
7203 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
7205 Apply --prefix to C++ skeletons too: they change the namespace.
7206 The test suite already exercize these cases.
7207 * data/c++.m4 (b4_namespace): New.
7208 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
7209 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
7210 * data/yacc.c, data/glr.c: Remove a useless `[]'.
7211 * doc/bison.texinfo: Document it.
7212 (Option Cross Key): Use @multitable in all formats. It looks
7213 nicer, even in TeX outputs.
7214 (Rules): Use the same code whatever the output type is.
7215 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
7216 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
7217 * tests/calc.at: Use it, instead of hard coding `yy'.
7219 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
7221 * TODO: Remove dead items.
7223 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
7225 * doc/FAQ: Remove, merged into...
7226 * doc/bison.texinfo (FAQ): this.
7227 * doc/Makefile.am (EXTRA_DIST): Adjust.
7229 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
7231 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
7233 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
7234 * doc/bison.texinfo (Calc++ Scanner): Use it.
7236 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
7238 Fix two nits reported by twlevo, plus one more that I discovered.
7240 * src/assoc.h (assoc_to_string): Give a name to the arg, as
7241 this is the usual Bison style.
7242 * src/location.h (location_print): Likewise.
7244 * src/reader.h (token_name): Likewise.
7246 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
7248 Fix some nits reported by twlevo.
7249 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
7250 and "POSIX". Use more-modern syntax for URLs. Mention C++
7251 and ask for Java. Don't hardwire OS version numbers. Add
7253 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
7254 * src/conflicts.c (solved_conflicts_obstack): Now static.
7256 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
7258 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
7259 page. Say "you can use it" not "you may use it" as on the web page;
7260 we're describing capabilities not granting permission.
7262 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
7264 * data/glr.c (yyresolveLocations): Rename local variables to avoid
7265 shadowing warnings. Use usual patter for iterating through RHS.
7266 * tests/glr-regression.at
7267 (Uninitialized location when reporting ambiguity):
7268 Modify yylex so that it uses its argument, rather than trying
7269 to rely on ARGSUSED (which doesn't work for gcc with warnings).
7270 const char -> char const.
7272 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
7273 Don't use tabs inside commands; it messes up 'ps'.
7274 Problem reported by twlevo.
7276 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
7278 * tests/glr-regression.at (Uninitialized location when reporting
7279 ambiguity): New test case.
7280 * data/glr.c (yyresolveLocations): New function, which uses
7282 (yyresolveValue): Invoke yyresolveLocations before reporting an
7284 * doc/bison.texinfo (Default Action for Locations): Note
7285 YYLLOC_DEFAULT's usage for ambiguity locations.
7286 (GLR Semantic Actions): Cross-reference those notes.
7288 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
7290 * tests/glr-regression.at (Leaked semantic values when reporting
7291 ambiguity): Remove unnecessary union and type declarations.
7292 (Leaked lookahead after nondeterministic parse syntax error): New test
7294 * data/glr.c (yyparse): Check for zero stacks remaining before
7295 attempting to shift the lookahead so that you don't lose it.
7297 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
7299 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
7300 * tests/glr-regression.at (Leaked semantic values when reporting
7301 ambiguity): New test case.
7302 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
7303 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
7304 now unnecessary yystackp parameter.
7305 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
7306 destructors can be called.
7308 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
7309 in existing testcases.
7311 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
7313 Don't leak semantic values for parent RHS when a user action cuts the
7314 parser, and clean up related code a bit.
7315 * tests/glr-regression.at (Leaked merged semantic value if user action
7316 cuts parse): Rename to...
7317 (Leaked semantic values if user action cuts parse): ... this. Add check
7318 for leaked parent RHS values.
7319 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
7320 between an unresolved state (non-empty chain of semantic options) and
7321 an incomplete one (signaled by an empty chain).
7322 (yyresolveStates): Document the interface. Move all manipulation of a
7323 successfully or unsuccessfully resolved yyGLRState to...
7324 (yyresolveValue): ... here so that yyresolveValue always leaves a
7325 yyGLRState with consistent data and thus is easier to understand.
7326 Remove the yyvalp and yylocp parameters since they are always just
7327 taken from the yys parameter. When reporting a discarded merged value
7328 in debugging output, note that it is incompletely merged. Document the
7330 (yyresolveAction): If resolving any of the RHS states fails, destroy
7331 them all rather than leaking them. Thus, as long as user actions are
7332 written to clean up the RHS correctly, yyresolveAction always cleans up
7333 the RHS of a semantic option. Document the interface.
7335 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
7337 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
7338 led to a segmentation fault in GNU Pascal. Problem reported
7341 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
7343 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
7344 mid-rule action inside a nonterminal symbol in order to declare a
7345 destructor for its semantic value.
7347 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
7349 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
7350 YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
7351 __cplusplus && ! defined _STDLIB_H && !
7352 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
7353 defined free))]: Include <stdlib.h> rather than rolling our own
7354 declarations of malloc and free, to avoid problems with
7355 incompatible declarations (using 'throw') C++'s stdlib.h. This
7356 should fix Debian bug 340012

7368 * NEWS: Version 2.1a.
7369 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
7370 since C99 requires this.
7372 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
7374 * m4/c-working.m4: New file.
7375 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
7377 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
7379 * Makefile.maint: Merge from coreutils.
7381 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
7383 More portability fixes for problems summarized by Nelson H. F. Beebe.
7385 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
7386 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
7387 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
7388 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this

7394 More portability fixes for problems summarized by Nelson H. F. Beebe.
7396 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
7397 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
7399 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
7400 nodist_PROGRAMS, since we don't need to actually compile the
7401 example if we're just doing a plain 'make'. This avoids bothering
7402 the installer unnecessarily about problems due to weird C++

7407 More portability fixes for problems summarized by Nelson H. F. Beebe.
7409 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
7410 than #include "...", and compile with -I'.'. The old method was
7411 not portable, according to Posix and the C standard, and it does
7412 not work with Sun C 5.7, where previous #line directives affect
7413 the working directory used in later #include "..." directives.

7424 '#include <map>' works and that you can apply ++ to iterators.
7426 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
7428 Work around portability problems summarized by Nelson H. F. Beebe in

7431 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
7432 that '#include <string>' works.
7434 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
7435 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
7436 "warning: sorry: semantics of inline function static data `const
7437 unsigned char translate_table[262]' are wrong (you'll wind up with
7440 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
7441 or, xor to not_, and_, or_, and xor_, respectively. This works
7442 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
7443 random system header somewhere that includes the equivalent of

7447 -E" works; it apparently doesn't work with PathScale EKO Compiler
7450 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
7452 During deterministic GLR operation, user actions should be able to
7453 influence the parse by changing yychar. To make this easier to fix and
7454 to make glr.c easier to evolve in general, don't maintain yytoken in
7455 parallel with yychar; just compute yytoken when needed.
7456 * tests/glr-regression.at (Incorrect lookahead during deterministic
7457 GLR): Check that setting yychar in a user action has the intended
7459 * data/glr.c (yyGLRStack): Remove yytokenp member.
7460 (yyclearin): Don't set *yytokenp.
7461 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
7462 yychar rather than *yytokenp to determine the current lookahead.
7463 Compute yytoken locally when needed.
7464 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
7467 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
7468 after `--report' documentation.

7479 all the test at once. This makes the output easier to read in the
7482 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
7483 got from <http://bro-ids.org/download.html>. The bug is that
7484 when two actions appeared in succession, the second one was
7485 scanned before the first one was added to the grammar rule
7486 as a midrule action. Bison then output the incorrect warning
7487 "parse.y:905.17-906.36: warning: unused value: $3".
7488 * src/parse-gram.y (BRACED_CODE, action): These are no longer
7489 associated with a value.
7490 (rhs): Don't invoke grammar_current_rule_action_append.
7491 (action): Invoke it here instead.
7492 * src/reader.c (grammar_midrule_action): Now extern.
7493 (grammar_current_rule_action_append): Don't invoke
7494 grammar_midrule_action; that is now the scanner's job.
7495 * src/reader.h (last_string, last_braced_code_loc):
7496 (grammar_midrule_action): New decls.
7497 * src/scan-gram.l (last_string): Now extern, sigh.
7498 (last_braced_code_loc): New extern variable.
7499 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
7500 rule already has an action.
7501 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
7502 * tests/input.at (AT_CHECK_UNUSED_VALUES):
7503 Add some tests to check that the above changes fixed the bug.
7505 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
7507 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
7508 All used changed. Check whether the symbol has a destructor,
7509 not whether it is typed.
7510 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
7511 that the values are still reported as unused. All line numbers

7525 Work around a bug in Pike 7.0, and give the Pike folks a
7526 better way to override the usual int widths.

7528 user can override the types.
7529 (short): #undef, to work around a bug in Pike 7.0.
7530 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
7531 (union yyalloc.yyss): Use yytype_int16 rather than short.
7533 (yysigned_char): Remove.
7534 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
7535 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
7536 * tests/regression.at (Web2c Actions): Adjust to above changes.
7538 * src/reader.c (check_and_convert_grammar): New function.

7545 to pacify gcc -Wswitch-default.

7552 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
7555 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>
7557 * Makefile.cfg (local-checks-to-skip): Add changelog-check,
7558 since we don't want to insist on a version number at the start
7559 of the changelog every time.
7560 * Makefile.maint: Sync from coreutils a bit better.
7561 (sc_trailing_blank): Renamed from sc_trailing_space.
7563 (sc_no_if_have_config_h, sc_require_config_h):
7564 (sc_prohibit_assert_without_use): New rules.
7565 (sc_obsolete_symbols): Don't catch Makefile.maint itself.
7566 (sc_dd_max_sym_length): Fix leading spaces in rule.

7568 (sc_useless_cpp_parens, m4-check): Output line numbers.
7569 (changelog-check): Allow version only in head.
7570 * data/c.m4: Use "defined FOO" instead of "defined (FOO)", to
7571 satisfy new Makefile.maint rule.

7749 in the yychar entry.
7750 In the yychar entry, remove mention of the local yychar case (pure
7751 parser) since this is irrelevant information when writing semantic
7752 actions and since it's already discussed in `Table of Symbols' where
7753 yychar is otherwise described as an external variable.
7754 In the yychar entry, don't call it the `current' look-ahead since it
7755 isn't when semantic actions are deferred.

7785 from which the RHS is taken. Set the lookahead members of the new

7788 yyaddDeferredAction.
7789 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

7800 (Incorrect lookahead during nondeterministic GLR): New test case.
7802 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

7814 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
7816 * data/glr.c (yyresolveValue): When merging semantic options, if at
7817 least one user action succeeds but a later one cuts the parse, then
7818 destroy the semantic value before returning rather than leaking it.
7819 (yyresolveStates): If a user action cuts the parse and thus
7820 yyresolveValue fails, ignore the (unset) semantic value rather than
7821 corrupting the yyGLRState, and empty the semantic options list since
7822 the user actions should have called all necessary destructors.
7823 Simplify code with YYCHK.
7824 * tests/glr-regression.at (Corrupted semantic options if user action
7825 cuts parse): New test case.
7826 (Undesirable destructors if user action cuts parse): New test case.

8054 (yylval, yylloc): If pure, #define to yystackp->yyval and
8055 yystackp->yyloc similar to yychar and yynerrs.
8056 (yyparse): If pure, remove local yylval and yylloc. Add local
8057 yystackp to accommodate pure definitions of yylval and yylloc.
8058 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
8059 yylvalp and yyllocp to &yylval and &yylloc.
8060 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
8061 namespace. Previously, nerrs and char were missing, but lval and lloc
8063 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
8064 yylvalp and yyllocp parameters since, if pure, these are now always
8065 accessible through yystackp. If not pure, they are still accessible
8067 * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
8068 `if (YYID (N))' to pacify lint.
8070 2005-12-21 Akim Demaille <akim@epita.fr>
8072 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
8073 destroy the RHS symbols of a rule.
8074 * data/yacc.c (yylen): Initialize to 0.
8075 Keep its value to the number of items to possibly shift.
8076 In particular, a regular successful parse that ends on YYFINAL by
8077 a (internal) YYACCEPT must not have yylen != 0.
8078 (yyerrorlab, yyreturn): Pop the RHS.
8079 Reorder a bit to emphasize the `shifting' bits of code.
8080 (YYPOPSTACK): Now accept a number of items to pop.
8081 * data/lalr1.cc: Likewise.
8082 * data/glr.c: Formatting changes.
8083 Use goto instead of fall through.
8084 * doc/bison.texinfo (Destructor Decl): Complete.
8086 2005-12-20 Juan Manuel Guerrero <juan.guerrero@gmx.de>
8088 * Makefile.am: DJGPP specific files added to EXTRA_DIST.
8089 * djgpp/Makefile.maint: Fix PACKAGE variable computation.
8090 * djgpp/config.bat: Replace every occurence of the file name
8091 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
8092 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
8093 * djgpp/config.sed: Replace every occurence of the file name
8094 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
8095 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
8096 * djgpp/djunpack.bat: DJGPP specific file.
8097 * djgpp/fnchange.lst: DJGPP specific file.
8098 * djgpp/README.in: Add new information about how to unpack the bison
8099 source on MSDOS and other systems which have 8.3 file name restrictions
8100 using djunpack.bat and fnchange.lst.
8102 2005-12-12 Paul Eggert <eggert@cs.ucla.edu>
8104 * bootstrap (build_cvs_prefix): Remove; unused.
8105 (CVS_PREFIX): Adjust to yesterday's Savannah reorganization
8106 when getting gnulib.
8108 2005-12-12 "Joel E. Denny" <jdenny@ces.clemson.edu>
8110 * data/glr.c: Reorder typedef declarations for structs to match order
8111 of struct declarations.

8123 * tests/sets.at (Accept): Fix typos in regular expression used to
8124 sed out the final state number.
8126 Work around portability problem on Solaris 10: flex-generated
8127 files include <stdio.h> before <config.h>, which messes up
8128 because the latter defines __EXTENSIONS__. Address the problem
8129 by creating two new little files that include <config.h> first,
8130 then include the flex-generated files. Rewrite everyone else
8131 to include <config.h> first, as well.
8132 * lib/timevar.c: Always include "config.h".
8133 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with
8134 scan-gram-c.c, and scan-skel.l with scan-skel-c.c.

8167 (current_lhs, current_lhs_location): Now static.
8168 (current_assoc): Remove unused variable.
8170 Cleanups so that Bison-generated parsers have less lint.
8171 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
8172 Prepend /*ARGSUSED*/, for lint's sake.
8173 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
8174 definition if 'lint' is defined.
8175 (YYID): New macro (or function, if lint).
8176 All uses of /*CONSTCOND*/0 replaced by YYID(0).
8177 * data/yacc.c: Likewise.
8178 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
8179 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
8180 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
8182 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
8183 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
8184 Use YYID(0) rather than 0, for lint.
8185 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
8186 (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.

8206 * NEWS: Document the following change.
8207 * data/yacc.c: Say "parser skeleton" rather than "file", since
8208 it's no longer just a file.
8209 * data/glr.c: Grant a special exception for C GLR parsers, that
8210 reads like the already-existing exception for C LALR(1) parsers.
8211 * data/glr.cc: Likewise.
8212 * data/lalr1.cc: Likewise.
8213 * data/location.cc: Likewise.
8214 * data/yacc.c: Reword the "written by" statement to clarify that
8215 it was the parser skeleton, not the entire output file.
8216 * data/glr.c: Written by Paul Hilfinger.
8217 * data/glr.cc: Written by Akim Demaille.

8222 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
8223 Fix typos in previous change that broke 'make check'.
8224 YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
8226 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
8227 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
8228 We can revert this once things settle down.
8230 * src/conflicts.c (conflicts_print): Don't print file name twice
8231 when %expect fails because there were no conflicts.
8232 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous
8234 * tests/conflicts.at (%expect not enough, %expect too much):
8235 (%expect with reduce conflicts): Adjust to new behavior.

8299 parser file (instead of the header).
8300 Wrap the implementations in a "namespace yy".
8302 2005-11-12 Akim Demaille <akim@epita.fr>
8304 Have glr.c include its header file when created.
8305 * data/glr.c (b4_shared_declarations): New.

8334 examples/calc++ if no C++ compiler is available. (trivial change)
8336 2005-11-09 Akim Demaille <akim@epita.fr>
8338 * src/scan-skel.l: Use a couple of asserts.
8340 2005-11-03 Akim Demaille <akim@epita.fr>
8342 In some (weird) cases, the final state number is incorrect.

8397 2005-10-14 Akim Demaille <akim@epita.fr>
8399 * examples/calc++/test: Use set -x only when VERBOSE.
8401 2005-10-13 Paul Eggert <eggert@cs.ucla.edu>

8436 that xlc complains about.
8437 * src/scan-skel.l (skel_wrap): Likewise.

8440 * data/yacc.c (YYMODERN_C): New macro, which also looks at
8441 __STDC_VERSION__. Use it everywhere instead of looking at

8452 * data/glr.c (YYUSE): New macro.
8453 (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
8454 Use it instead of rolling our own.
8455 (YYLLOC_DEFAULT, YYCHK, YYDPRINTF, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
8457 Use /*CONSTCOND*/ to suppress lint warnings.
8458 * data/lalr1.cc (YYLLOC_DEFAULT, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
8459 (YY_STACK_PRINT): Use 'false' not '0'.
8461 (yysymprint_, yydestruct_): Use it instead of rolling our own.

8468 * data/m4sugar/m4sugar.m4 (_m4_map): New macro.
8469 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
8471 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
8473 Undo the parts of the unlocked-I/O change that substituted
8474 putc or puts for printf. This might hurt performance a bit,
8475 but some people prefer the printf style.
8476 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
8477 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

8487 * src/output.c (escaped_output): Likewise.
8488 (user_actions_output): Break apart two printfs.

8494 * data/glr.c (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
8495 Use assignments rather than casts-to-void to suppress
8496 unused-variable warnings. This pacifies 'lint'.
8497 * data/lalr1.cc (yysymprint_, yydestruct_): Use a call to suppress
8498 unused-variable warnings.
8500 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>
8502 * Makefile.am: DJGPP specific files added to EXTRA_DIST.
8504 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
8506 Use unlocked I/O for a minor performance improvement on hosts like
8507 GNU/Linux and Solaris that support unlocked I/O. The basic idea
8508 is to use the gnlib unlocked-io module, and to prefer putc and
8509 puts to printf when either will work (since the latter doesn't
8510 come in an unlocked flavor).
8511 * bootstrap (gnulib_modules): Add unlocked-io.
8512 * data/c.m4 (yysymprint): Prefer puts and putc to printf.

8578 to allow support for non-posix systems. This is a no-op function
8581 * lib/subpipe.h: New function end_of_output_subpipe() added

8670 local variables whose names begin with 'yy'.
8671 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
8672 Trivial changes from Joel E. Denny.
8674 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
8676 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
8677 don't use alloca any more.
8679 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
8680 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
8681 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
8682 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
8683 to match yacc.c, to test more hosts.
8685 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
8687 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
8688 doesn't affect behavior.
8689 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
8691 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
8692 This works a bit better with glibc, if user code has already included
8694 * doc/bison.texinfo (Bison Parser): Document that users can't
8695 arbitrarily use malloc and free for other purposes. Document
8696 that <alloca.h> and <malloc.h> might be included.
8697 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
8698 user must declare alloca.

8707 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
8709 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
8710 (YYSTACK_ALLOC_MAXIMUM): Use it.
8711 (yysyntax_error): New function.
8712 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
8713 multiple syntax errors are reported, and alloca is being used.
8714 Instead, reallocate buffers twice as big each time, so that
8715 we waste at most half the allocated memory. Start with a small
8716 (128-byte) buffer that will suffice in most cases anyway.
8717 Use yysyntax_error to do most of the work.
8719 * doc/bison.texinfo (Error Reporting, Table of Symbols):
8720 yynerrs is the number of errors reported, not the number of
8723 * tests/glr-regression.at (Duplicated user destructor for lookahead):
8724 Mark it as expected to fail.
8725 Cast result of malloc; problem reported by twlevo@xs4all.nl.
8726 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
8727 Don't start user-code symbols with "yy", to avoid name space problems.
8729 2005-09-19 Akim Demaille <akim@epita.fr>
8731 Remove the traits, failed experiment.
8732 It never proved useful, and anyway because of the current
8733 definition, it was not possible to have several specialization of
8734 this traits, making it useless.
8735 * data/lalr1.cc (yy:traits): Remove.
8736 Inline its definitions in the parser class.
8738 2005-09-19 Akim Demaille <akim@epita.fr>

8760 * src/output.c (prepare): Likewise.
8761 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
8762 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
8763 is not defined. This is an awful hack, but it's enough for now.
8764 All callers changed.
8765 * tests/glr-regression-at (make_value): Args are const pointers now,
8766 to avoid GCC warning.
8767 (Duplicated user destructor for lookahead): New test. Currently
8768 skipped. It fails on my host but I'm not sure it'll always fail.
8770 2005-09-16 Akim Demaille <akim@epita.fr>
8772 * src/symtab.h (struct symbol): Declare the printer and destructor
8773 as const, to avoid accidental calls to free.
8774 (symbol_destructor_set, symbol_printer_set): Adjust.
8775 * src/symtab.c: Adjust.
8777 2005-09-16 Akim Demaille <akim@epita.fr>
8779 * data/c.m4 (b4_token_enums): New.
8780 (b4_token_defines): Rename as...
8781 (b4_token_enums_defines): this.
8782 (b4_token_defines): New, output only the #defines.
8783 * data/yacc.c, data/glr.c: Adjust.
8784 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
8785 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
8788 2005-09-16 Akim Demaille <akim@epita.fr>
8790 * data/lalr1.cc (yylex_): Remove, inline its code.
8791 (yyreport_syntax_error_): Remove, replaced by...
8792 (yysyntax_error_): this which returns a string and leaves to the
8793 caller the call to the users' error function.
8794 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
8795 Move from members of the parser object...
8796 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
8797 to local variables of the parse function.
8799 2005-09-16 Akim Demaille <akim@epita.fr>
8801 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
8802 since it's in Bison's name space.
8804 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
8806 * data/glr.c (yyresolveValue): Add default case to pacify
8807 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
8809 * NEWS: Document when yyparse started to return 2.
8810 * doc/bison.texinfo (Parser Function): Document when yyparse
8813 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
8814 (b4_filename_type): Renamed back from b4_file_name_type. All uses
8816 (class position): file_name -> filename (reverting). All uses changed.
8818 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
8820 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
8821 do anything if $@ exists. This reverts part of the 2005-07-07
8824 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
8826 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
8827 contains obsolete information and isn't worth distributing as a
8828 separate file anyway.
8829 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
8830 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
8831 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
8832 (yyparse): Abort if user code uses longjmp to throw an unexpected
8835 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
8837 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
8838 Suggested by twlevo@xs4all.nl.
8840 * data/glr.c (YYCHK1): Do not assume YYE is in range.
8841 This avoids a diagnostic from gcc -Wswitch-enum.
8842 Problem reported by twlevo@xs4all.nl.
8844 * doc/bison.texinfo: Don't use "filename", as per GNU coding
8845 standards. Use "file name" or "file" or "name", depending on
8847 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
8848 not to hack/foo.tab.c.
8849 (Calc++ Top Level): 2nd arg of main is not const.
8850 * data/glr.c: b4_filename -> b4_file_name.
8851 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
8853 (class position): filename -> file_name. All uses changed.

8864 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
8865 to accommodate latest gnulib.
8867 * tests/glr-regression.at (Duplicate representation of merged trees):
8868 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
8870 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
8873 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
8875 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
8876 All uses changed. Invoke user destructor after an error during a
8877 split parse (trivial change from Joel E. Denny).
8879 * tests/glr-regression.at
8880 (User destructor after an error during a split parse): New test case.
8881 Problem reported by Joel E. Denny in:
8882 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
8884 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
8886 * README-cvs: Give URLs for recommended tools.
8887 Mention Gzip version problem, and bootstrapping issues.
8888 Remove troubleshooting section, as it's somewhat obsolete.
8890 * bootstrap (no_cache): New var, to accommodate different wget
8891 variants. Use it instead of '-C off'. Problem reported by
8894 * data/glr.c (yydestroyStackItem): New function.
8895 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
8896 debugging information. Problem reported by Joel E. Denny.

8906 * tests/glr-regression.at
8907 (User destructor for unresolved GLR semantic value): New test case.
8908 Problem reported by Joel E. Denny in:
8909 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
8911 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
8913 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
8915 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
8916 lib-prefix.m4, po.m4.
8918 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
8919 in yydestruct diagnostic, since it might not be an error.
8920 Problem reported by Joel Denny near end of
8921 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
8922 * data/lalr1.cc (yyerturn): Likewise.
8923 * data/yacc.c (yyreturn): Likewise.
8924 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
8926 * src/files.c: Remove obsolete FIXME comment.
8928 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
8929 with the other templates, and to fix bogus run-on messages such
8930 as the one reported at the end of
8931 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
8932 All callers changed to avoid the newline.
8933 (yyprocessOneStack): Output two lines rather than one, to accommodate
8934 the above change. This changes the debug output format slightly.
8936 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
8937 reported by Joel E. Denny in
8938 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
8940 * tests/glr-regression.at (Duplicate representation of merged trees):
8941 New test, from Joel E. Denny in:
8942 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
8943 * THANKS: Add Joel E. Denny.
8945 * configure.ac (AC_INIT): Bump to 2.0c.
8947 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
8949 * NEWS: Version 2.0b.
8951 * Makefile.am (SUBDIRS): Put examples before tests, so that
8952 "make check" doesn't finish with "All 1 tests passed".
8954 * tests/regression.at (Token definitions): Don't rely on
8955 AT_PARSER_CHECK for data that contains backslashes. It currently
8956 uses 'echo', and 'echo' isn't portable if its argument contains
8957 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
8958 that the byte '\0xff' is not printable in the C locale; it is,
8959 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
8960 not printable, so use '\0x81' to test.
8962 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
8963 version of GCC, since the macro is used with non-GCC compilers.
8965 Fix core dump reported by Pablo De Napoli in
8966 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
8967 * tests/regression.at (Invalid inputs with {}): New test.
8968 * src/parse-gram.y (token_name): Translate type before using
8971 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
8972 the user's name space. All uses changed to __attribute__
8974 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
8975 Add __attribute__ ((__noreturn__)).
8977 * etc/clcommit: Remove. We weren't using it, and it failed
8978 "make maintainer-distcheck".
8979 * Makefile.maint: Merge from coreutils.
8980 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
8981 (syntax-check-rules): Change list of rules as described below.
8982 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
8983 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
8984 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
8985 (sc_trailing_space): New rules.
8986 (sc_xalloc_h_in_src): Remove.
8987 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
8988 (sc_space_tab, sc_error_exit_success, sc_changelog):
8989 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
8990 (makefile-check, po-check, author_mark_check):
8991 (makefile_path_separator_check, copyright-check):
8992 Use grep -n, to make it easier to find violations.
8993 Use CVS_LIST and CVS_LIST_EXCEPT.
8994 (header_regexp, h_re): Remove.
8996 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
8997 (my-distcheck): Use more-modern GCC flags.
8998 (signatures, %.asc): Remove.
8999 (rel-files, announcement): Remove signatures.
9000 Restore old updating code, even though we don't use it, so
9001 that we're the same as coreutils.
9002 (alpha, beta, major): Depend on news-date-check.
9003 Make the upload commands.
9005 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.

9012 * tests/sets.at: Likewise.
9014 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
9015 we comment out the Autoconf version number.
9016 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
9017 it's error-prone and "make maintainer-distcheck" rejects it.
9019 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
9020 Indent calls to "error" to pacify "make maintainer-distcheck",
9021 when the calls are not intended to be translated.
9022 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
9024 * src/Makefile.am (DEFS): Use +=, to pacify
9025 "make maintainer-distcheck".
9026 (bison_SOURCES): Add scan-skel.h.
9027 (sc_tight_scope): New rule, from coreutils.
9029 * src/files.c (src_extension, header_extension):
9030 Now static, not extern.
9031 * src/getargs.c (short_options): Likewise.
9032 * src/muscle_tab.c (muscle_table): Likewise.
9033 * src/parse-gram.y (current_class, current_type, current_prec):
9035 * src/reader.c (grammar_end, previous_rule_end): Likewise.
9036 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
9037 * src/main.c (main): Cast bindtextdomain and textdomain calls to
9038 void, to avoid warning when NLS is disabled.
9039 * src/output.c: Include scan-skel.h.
9040 (scan_skel): Remove decl, since scan-skel.h does this.
9042 Indent calls to "error" to pacify "make maintainer-distcheck".
9043 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
9044 * src/reader.h (gram_end, gram_lineno): New decls to pacify
9045 "make maintainer-distcheck".
9046 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
9047 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
9048 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
9049 (skel_lex_destroy, scan_skel): Move these decls to...
9050 * src/scan-skel.h: New file.
9051 * src/uniqstr.c (uniqstr_assert):
9052 Indent calls to "error" to pacify "make maintainer-distcheck".
9054 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
9057 * tests/torture.at: Revamp to avoid misuse of atoi that
9058 "make maintainer-distcheck" complained about.
9060 * examples/extexi (message): Don't print a message more than once,
9061 and omit line-number decoration that makes Emacs compile think
9062 that informative messages are worth worrying about.
9064 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
9066 * configure.ac: Update version number.
9068 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
9070 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
9071 autogenerated by the maintainer.
9072 * examples/calc++/.cvsignore: Add *.yy.
9074 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
9075 * lib/bitset_stats.c (bitset_stats_init): Likewise.
9076 * lib/bitsetv.c (bitsetv_alloc): Likewise.
9078 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
9080 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
9081 from maintainer-distcheck about casting the argument of 'free'.
9083 * NEWS: Mention recent yytname changes.
9084 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
9086 * bootstrap: For translations that have not yet been upgraded to
9087 the new runtime-po domain, prime the pump by extracting the
9088 relevant strings from the obsolete translations. This code can be
9089 removed once the bison-runtime domain has been translated by each
9092 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
9093 now that token names are already quoted.
9095 Fix problem reported by Anthony Heading.
9096 * data/glr.c (YYTOKEN_TABLE): New macro.
9097 (yytname): Define if YYTOKEN_TABLE.
9098 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
9099 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
9100 (YYERROR_VERBOSE): Define the same way the other skeletons do.
9101 * src/output.c (prepare_symbols): Output token_table_flag.
9103 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
9105 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
9106 again if the first call fails.
9108 * data/glr.c (yytnamerr): New function.
9109 (yyreportSyntaxError): Use it to dequote most string literals.
9110 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
9111 with other skeletons. All uses changed.
9112 (yytnameerr_): New function.
9113 (yyreport_syntax_error): Use it to dequote most string literals.
9114 * data/yacc.c (yytnamerr): New function.
9115 (yyerrlab): Use it to decode most string literals.
9116 * doc/bison.texinfo (Decl Summary, Calling Convention):
9117 Clarify quoting convention of yytname.
9118 * src/output.c (prepare_symbols): Quote all names. This undoes
9119 the 2005-04-17 change, which is now accomplished (mostly) via
9120 changes in the parsers as described above.
9121 * tests/regression.at (Token definitions, Web2c Actions):
9122 Undo most 2005-04-17 change here, too.
9124 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
9126 Fix more problems reported by twlevo@xs4all.nl.
9127 * tests/cxx-type.at: Don't pipe output of ./types through sed to
9128 remove trailing spaces. This loses the exit status of ./types,
9129 and isn't needed since ./types shouldn't be emitting trailing
9131 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
9132 as the stack isn't valid in that case.
9134 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
9135 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
9136 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
9137 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
9139 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
9140 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
9141 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
9144 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
9145 overly-picky compilers that reject 'char *foo = "bar";'.
9147 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
9148 to FILE * parameter, not to stderr. This fixes a typo introduced
9149 in the 2005-07-12 change.
9151 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
9152 warnings from GCC 4.
9154 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
9155 (yyglrShiftDefer, yysplitStack):
9156 Remove unused parameters b4_pure_formals. All uses changed.
9157 (yyglrShift): Remove unused parameters b4_user_formals.
9159 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
9161 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
9163 Destructor cleanups and regularization among the three skeletons.
9164 * NEWS: Document the behavior changes.
9165 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
9166 stack before failing, as the cleanup code will do it for us now.
9167 * data/lalr1.cc (yyerrlab): Likewise.
9168 * data/glr.c (yyparse): Pop everything off the stack before
9169 freeing it, so that destructors get called properly.
9170 * data/lalr1.cc (yyreturn): Likewise.
9171 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
9172 This is more consistent.
9173 * doc/bison.texinfo (Destructor Decl): Mention more reasons
9174 why destructors might be called. 1.875 -> 2.1.
9175 (Destructor Decl, Decl Summary, Table of Symbols):
9176 Some English-language cleanups for %destructor.
9177 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9178 Add output line for destructor of start symbol.
9179 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
9180 because of that same extra output line.
9182 * NEWS: Document minor wording changes in diagnostics of
9183 Bison-generated parsers.
9184 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
9185 Remove unused formals. All uses changed.
9186 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
9187 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
9188 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
9189 Rename yyoverflowab to yyexhaustedlab.
9190 When memory exhaustion occurs during syntax-error reporting,
9191 report it separately rather than in a single diagnostic; this
9193 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
9194 (Memory Exhausted): Renamed from Parser Stack Overflow.
9195 Revamp wording slightly to prefer "memory exhaustion".
9196 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
9198 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
9200 Add i18n support to the GLR skeleton. Partially fix the C++
9201 skeleton; a C++ expert needs to finish this. Remove debugging
9202 msgids; there's little point to having them translated, since they
9203 can be understood only by someone who can read the
9204 (English-language) source code.
9206 Generate runtime-po/bison-runtime.pot automatically, so that we
9207 don't have to worry about garbage getting in that file. We'll
9208 make sure after the next official release that old msgids don't
9210 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
9212 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
9214 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
9215 Fix typos in explanations of the runtime file.
9216 * bootstrap: Change gettext keyword from YYI18N to YY_.
9217 Use standard Makefile.in.in in runtime-po, since we'll arrange
9218 for backward-compatible bison-runtime.po files in a different way.
9219 * data/glr.c (YY_): New macro, from yacc.c.
9220 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
9221 Translate messages intended for users.
9222 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
9223 the wording in the other skeletons. We don't know that the memory
9225 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
9226 Use same method that yacc.c uses.
9227 Don't translate debugging messages.
9228 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
9229 it doesn't work (yet), and requires C++ expertise to fix.
9230 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
9231 Move defn to a more logical place, to be consistent with other
9233 Don't translate debugging messages.
9234 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
9235 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
9236 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
9237 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
9239 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
9240 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
9242 * tests/glr-regression.at (Badly Collapsed GLR States):
9244 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
9245 yylex should return 0 at EOF rather than aborting.
9247 Improve tests for stack overflow in GLR parser.
9248 Problem reported by twlevo@xs4all.nl.
9249 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
9251 (yyStackOverflow): Just longjmp, but with value 2 so that caller
9252 can handle the problem.
9253 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
9254 (yyparse): New local variable yyresult to record the result.
9255 Use result of setjmp to set it, rather than storing itinto
9257 (yyDone): Remove label.
9258 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
9259 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
9260 if YYABORT is used).
9261 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
9262 yyparse status; put status > 1 into diagnostic.
9263 Check that status==2 works.
9264 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
9265 Use exit status 3 for failure to open (which shouldn't happen).
9267 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
9269 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
9270 1 on syntax error; just let yyparse do its thing.
9271 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
9272 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
9273 (Exploding the Stack Size with Alloca):
9274 (Exploding the Stack Size with Malloc):
9275 Expect exit status 2, not 1, since the parser is supposed to blow
9276 its stack. Problem reported by twlevo@xs4all.nl.
9278 * data/glr.c (yyparse): Don't assume that the initial calls
9279 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
9280 Print a stack-overflow message and fail instead.
9281 Initialize the line-number information before creating the stack,
9282 so that the stack-overflow message can report line zero safely.
9284 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
9286 Fix problems reported by twlevo@xs4all.nl.
9287 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
9288 (yyuserMerge): Provide a default case if b4_mergers is empty.
9289 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
9290 * tests/glr-regression.at
9291 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
9292 Add casts to pacify C++ compilers.
9293 * tests/glr-regression.at (Improper merging of GLR delayed action
9294 sets): Declare yylex before using it.
9295 * tests/Makefile.am (maintainer-check-g++): Fix a stray
9296 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
9297 test for valgrind; valgrind is independent of g++.
9298 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
9299 for compatibility with POSIX 1003.1-2001 (if running coreutils).
9300 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
9301 Use a destructor, so that we can expand the stack. Change
9302 YYSTYPE to char * so that we can free it. Cast result of malloc.
9304 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9306 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
9307 a valgrind failure. Problem reported by twlevo@xs4all.nl.
9309 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
9311 * PACKAGING: New file, suggested by Bruno Haible and taken from
9312 similar wording in gettext's PACKAGING file.
9313 * NEWS: Mention PACKAGING.
9314 * Makefile.am (EXTRA_DIST): Add PACKAGING.
9316 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
9318 * NEWS: Document recent i18n improvements.
9319 * bootstrap: Get runtime translations into runtime-po.
9320 Create runtime-po files automatically, if possible.
9321 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
9322 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
9323 does not infringe on the user's name space.
9324 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
9325 * doc/bison.texinfo (Internationalization): Revamp the English
9326 and Texinfo syntax a bit, to try to make it clearer.
9327 (Bison Options, Option Cross Key): Mention --print-localedir.
9328 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
9329 YYENABLE_NLS. Quote a bit more.
9330 * runtime-po/.cvsignore: New file.
9331 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
9332 * runtime-po/Rules-quot: Remove; now created by bootstrap.
9333 * runtime-po/quot.sed: Likewise.
9334 * runtime-po/boldquot.sed: Likewise.
9335 * runtime-po/en@quot.header: Likewise.
9336 * runtime-po/en@boldquot.header: Likewise.
9337 * runtime-po/insert-header.sin: Likewise.
9338 * runtime-po/remove-potcdate.sin: Likewise.
9339 * runtime-po/Makevars: Likewise.
9340 * runtime-po/LINGUAS: Likewise.
9341 * runtime-po/de.po: Likewise; we will rely on the translation project
9342 to maintain this, so "bootstrap" should get it.
9343 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
9345 * src/main.c (main): Bind the bison-runtime domain, too.
9347 2005-07-12 Bruno Haible <bruno@clisp.org>
9349 * data/yacc.c: Include <libintl.h> when NLS is enabled.
9350 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
9351 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
9352 * runtime-po: New directory.
9353 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
9354 $(DOMAIN).pot-update rule, so that old messages are never dropped.
9355 * runtime-po/Rules-quot: New file, copied from po/.
9356 * runtime-po/quot.sed: Likewise.
9357 * runtime-po/boldquot.sed: Likewise.
9358 * runtime-po/en@quot.header: Likewise.
9359 * runtime-po/en@boldquot.header: Likewise.
9360 * runtime-po/insert-header.sin: Likewise.
9361 * runtime-po/remove-potcdate.sin: Likewise.
9362 * runtime-po/Makevars: New file.
9363 * runtime-po/POTFILES.in: New file.
9364 * runtime-po/LINGUAS: New file.
9365 * runtime-po/bison-runtime.pot: New file.
9366 * runtime-po/de.po: New file.
9367 * m4/bison.m4: New file.
9368 * Makefile.am (SUBDIRS): Add runtime-po.
9369 (aclocaldir, aclocal_DATA): New variables.
9370 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
9372 * src/getargs.c (usage): Document --print-localedir option.
9373 (PRINT_LOCALEDIR_OPTION): New enum item.
9374 (long_options): Add --print-localedir option.
9375 (getargs): Handle --print-localedir option.
9376 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
9377 (Internationalization): New section.
9379 2005-07-12 Akim Demaille <akim@epita.fr>
9381 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
9382 for consistency with the rest of the code.
9383 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
9386 2005-07-12 Akim Demaille <akim@epita.fr>
9388 * src/parse-gram.y: Use %printer instead of YYPRINT.
9390 2005-07-12 Akim Demaille <akim@epita.fr>
9392 * src/symtab.h, src/symtab.c (symbol_print): New.
9393 * src/symlist.h, src/symlist.c (symbol_list_print): New.
9394 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
9396 2005-07-12 Akim Demaille <akim@epita.fr>
9398 * data/glr.c (b4_syncline): Fix (swap) the definitions of
9399 b4_at_dollar and b4_dollar_dollar.
9401 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
9403 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
9404 and Pennello's paper.
9406 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
9408 * data/yacc.c (yyparse): Undo previous patch. Instead,
9409 set yylsp[0] and yyvsp[0] only if the initial action
9410 sets yylloc and yylval, respectively.
9412 * data/yacc.c (yyparse): In the initial action, set
9413 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
9414 This avoids the use of undefined variables if the initial
9415 action does not set yylloc and/or yylval.
9417 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
9419 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
9420 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
9421 Remove from CVS. These files are automatically generated.
9422 * examples/extexi: Clarify that this file is now part of Bison,
9423 not GNU M4, and that it works with any POSIX-compatible Awk.
9424 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
9425 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
9426 so that we also get calc++-parser.yy. Geneate it.
9427 Use $(AWK), not gawk, since any conforming Awk will do.
9428 Put comment before action, since older 'make' can't handle comment
9430 $(BUILT_SOURCES): List all built sources, not just some of them.
9431 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
9432 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
9433 $($(calc_sources_generated)): Remove unnecessary test for existence
9434 of target. (This had a shell syntax error anyway; a stray "x".)
9435 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
9437 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
9439 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
9440 implied by the other modules.

9450 * configure.ac, Makefile.am: Adjust.
9451 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
9453 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
9455 * data/glr.c (yyFail): Drastically simplify; since the format argument
9456 never had any % directives, we can simply pass it to yyerror.
9457 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
9458 be modified later, as that is the usual style in glr.c.
9459 Problems reported by Paul Hilfinger.
9461 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
9462 and size overflow errors.
9463 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
9464 in case the user prolog sets feature-test macros like _GNU_SOURCE.
9465 (YYSIZEMAX): New macro.
9466 (yystpcpy): New function, taken from yacc.c.
9467 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
9468 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
9469 so that we don't have to maintain their signatures.
9470 (yyFail): Check for buffer overflow, by using vsnprintf rather
9471 than vsprintf. Allocate a bigger buffer if possible.
9472 Report an error if buffer allocation fails.
9473 (yyStackOverflow): New function.
9474 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
9475 the initialization was successful. It might fail if storage was
9477 (yyexpandGLRStack): Add more checks for storage allocation failure.
9478 Use yyStackOverflow to report failures.
9479 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
9480 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
9481 Don't assume stack number fits in int.
9482 (yysplitStack): Check for storage allocation failure.
9483 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
9484 can print diagnostics on storage allocation failure. All callers
9486 (yyresolveValue): Use yybool for boolean.
9487 (yyreportSyntaxError): Check for size-calculation overflow.
9488 This code is taken from yacc.c.
9489 (yyparse): Check for storage allocation errors when allocating
9492 2005-07-05 Akim Demaille <akim@epita.fr>
9494 Extract calc++ from the documentation.
9495 * doc/bison.texinfo (Calc++): Add the extraction marks.
9496 * examples/extexi: New, from the aborted GNU Programming 2E.
9497 Separate the different paragraph of a file with empty lines.
9498 * examples/Makefile: Use it to extract the whole calc++ example.
9500 2005-06-24 Akim Demaille <akim@epita.fr>

9505 2005-06-22 Akim Demaille <akim@epita.fr>
9507 * doc/bison.texinfo (C++ Language Interface): First stab.
9508 (C++ Parsers): Remove.
9510 2005-06-22 Akim Demaille <akim@epita.fr>
9512 * data/lalr1.cc (yylex_): Honor %lex-param.
9514 2005-06-22 Akim Demaille <akim@epita.fr>

9520 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
9521 * examples/calc++/compile, examples/calc++/test: New.
9523 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
9525 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
9526 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
9527 which stems from the 2005-05-27 patch.
9529 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
9531 * data/glr.c: Modify treatment of unused parameters to permit use
9532 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
9534 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
9536 Fix infringement on user name space reported by Janos Zoltan Szabo.
9537 * data/yacc.c (yyparse): strlen -> yystrlen.
9539 2005-05-30 Akim Demaille <akim@epita.fr>
9541 * data/lalr1.cc (_): New.
9542 Translate the various messages.
9544 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
9546 Fix infringement on user name space reported by Bruno Haible.
9547 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
9548 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
9549 the user's name space.
9550 (alloca): Include <stdlib.h> to get it, if it's not built in.
9551 (YYMALLOC, YYFREE): Define only if needed.
9552 (malloc, free): Declare, but only if needed, as this infringes on
9553 the user name space.
9555 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
9557 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
9558 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
9560 * lib/ebitset.c (min, max): Undef before defining.
9561 * lib/vbitset.c (min, max): Likewise.
9562 * lib/subpipe.c (create_subpipe): Save local variables in case
9563 vfork clobbers them.
9565 2005-05-24 Bruno Haible <bruno@clisp.org>
9567 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
9568 error message syntax used by gcc-4.0.
9570 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>

9573 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
9575 * bootstrap: Remove workaround for problem I encountered with
9576 gettext 0.14.1; it seems to be fixed now.
9578 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
9580 * NEWS: Version 2.0a.
9582 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
9583 the previous change.
9585 Various maintainer cleanups.
9586 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
9587 conftest*, for benefit of CVS commands run at the same time as
9588 "configure". Add build-aux, since "bootstrap" now creates it and
9590 * Makefile.cfg (move_if_change): Remove.
9591 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
9592 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

9597 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
9599 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
9600 this is now the recommended name.
9601 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
9602 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
9603 ylwrap. These files now go into build-aux.
9604 * config/move-if-change: Remove.
9605 * config/prev-version.txt: Bump from 1.75 to 2.0.
9607 * bootstrap: Add stdio-safer, unistd-safer modules.

9611 fopen-safer.c, stdio-safer.h, unistd-safer.h.
9612 * lib/subpipe.c: Include "unistd-safer.h".
9613 (create_subpipe): Make sure all the newly-created
9614 file descriptors are > 2, so that diagnostics don't
9615 get sent down them (which might cause Bison to hang, in theory).
9616 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
9617 * src/files.c (xfopen): Use fopen_safer, not fopen.
9619 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
9620 yesterday's yacc.c fix.
9622 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>

9626 Fix a destructor bug reported by Wolfgang Spraul in
9627 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
9628 * data/yacc.c (yyabortlab): Don't call destructor, and
9629 don't set yychar to EMPTY.
9630 (yyoverflowlab): Don't call destructor.
9631 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
9632 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
9633 since we no longer output the message "discarding lookahead token
9636 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9638 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
9639 fix a small glitch in debugging output.
9640 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
9641 after YY_SYMBOL_PRINT where needed.

9695 Problem reported by Ralf Menzel.
9697 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
9699 * tests/actions.at: Test that stack overflow invokes destructors.
9700 From Marcus Holland-Moritz.
9701 * data/yacc.c (yyerrlab): Move the code that destroys the stack
9703 (yyreturn): to here. That way, destructors are called properly
9704 even if the stack overflows, or the user calls YYACCEPT or
9705 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
9706 (yyoverflowlab): Destroy the lookahead.
9708 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
9710 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
9712 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
9714 * NEWS: Bison-generated C parsers no longer quote literal strings
9715 associated with tokens.
9716 * src/output.c (prepare_symbols): Don't escape strings,
9717 since users don't want to see C escapes.
9718 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
9720 * tests/input.at (Torturing the Scanner): Likewise.
9721 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
9723 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
9725 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
9726 the data size is known to be too small and we can't increase it.
9727 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
9729 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
9731 * src/parse-gram.y: Include quotearg.h.
9732 (string_as_id): Quote $1 before using it as a key, since the
9733 lexer no longer quotes it for us.
9734 (string_content): Don't strip quotes, since lexer no longer
9736 * src/scan-gram.l: Include quotearg.h.
9738 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
9739 a key, since the rest of the lexer doesn't quote it.
9740 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
9741 * tests/regression.at (Token definitions): Check for backslashes
9744 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
9745 (YYSIZE_T): Define to unsigned long int when using an older compiler.
9746 (yyparse): Revamp code to generate long syntax error message, to
9747 make it easier to translate, and to avoid problems with arithmetic
9748 overflow. Change "virtual memory" to "memory" in diagnostic, since
9749 we don't know whether the memory is virtual.
9751 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
9753 * NEWS: Bison-generated C parsers now use the _ macro to
9755 * data/yacc.c (_) [!defined _]: New macro.
9756 All English strings wrapped inside this macro.
9757 * doc/bison.texinfo (Bison Parser): Document _.
9758 * po/POTFILES.in: Include src/parse-gram.c, since it now
9759 includes translateable strings that parse-gram.y doesn't.
9761 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
9763 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
9764 reverting the 2004-10-11 change to this function.
9765 (symbol_check_alias_consistency): Don't call symbol_type_set
9766 if the type name is already correct.
9767 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
9769 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
9771 * tests/regression.at (Token definitions): Don't use a token named
9772 c, as that generates a "#define c ..." that runs afoul of buggy
9773 stdlib.h that uses the identifier c as a member of struct
9774 drand48_data. Problem reported by Horst Wente.
9776 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
9778 * bootstrap: Change translation URL from
9779 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
9780 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
9781 redirection glitches. Problem reported by twlevo@xs4all.nl.
9783 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
9785 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
9786 after operands; POSIX says this isn't portable for the c99 command.
9788 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
9790 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
9791 immediately if a data overrun has occurred; this may help us track
9792 down what may be a spurious failure on MacOS.
9794 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
9796 Respond to problems reported by twlevo@xs4all.nl.
9798 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
9800 * src/vcg.h: Comment fix.
9801 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
9802 (G_CMAX): Change to -1 instead of INT_MAX.
9804 * data/yacc.c (yyparse): Omit spaces before #line.
9806 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
9808 * src/tables.c (state_number_to_vector_number): Put it inside an
9809 "#if 0", since it's not currently used. Problem reported by
9812 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
9814 * src/output.c (escaped_output): Renamed from
9815 escaped_file_name_output, since we now use it for symbol tags as
9816 well. All uses changed.
9817 (symbol_destructors_output, symbol_printers_output):
9818 Escape symbol tags too.
9819 Problem reported by Matyas Forstner in
9820 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
9822 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
9824 * src/output.c (user_actions_output, token_definitions_output,
9825 symbol_destructors_output, symbol_printers_output): Likewise.
9826 * src/reader.c (prologue_augment): Likewise.
9827 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
9829 * src/vcg.c (output_edge): Don't quote linestyle arg.
9830 Problem reported by twlevo@xs4all.nl.
9832 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
9834 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
9835 example, reported by Derek M Jones. Also, make the example even
9836 more outrageous, to better illustrate how bad the problem is.
9838 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
9840 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
9841 putsym. Typo reported by Sebastian Piping.
9843 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
9845 * doc/bison.texinfo (Language and Grammar): some -> same
9846 (Epilogue): int he -> in the
9847 Typos reported by Sebastian Piping via Justin Pence.
9849 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
9851 * tests/glr-regression.at (Improper handling of embedded actions
9852 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
9853 embedded actions and $-N in GLR parsers", work around an Autoconf bug
9854 with dollar signs in test names.
9855 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
9856 for a similar reason.
9858 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9860 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
9861 wants to redefine G_VIEW.
9863 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
9865 * src/vcg.c (get_view_str): Remove case for normal_view.
9866 Problem reported by twlevo@xs4all.nl.
9868 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
9870 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
9871 Problem reported by twlevo@xs4all.nl.
9873 * doc/bison.texinfo: Change @dircategory from "GNU programming
9874 tools" to "Software development". Requested by Richard Stallman
9877 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
9879 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
9880 Problem reported by twlevo@xs4all.nl.
9882 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
9884 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
9885 keyword; it's not needed with modern compilers, and it doesn't
9886 affect correctness with older compilers. Suggested by
9889 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
9891 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
9892 gcc -Wswitch-default.
9893 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
9894 * data/yacc.c (yyparse): Likewise.
9896 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
9898 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
9899 already. Let config.h define any nonstandard values.
9901 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
9903 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
9904 for the benefit of slower hosts. Problem reported by
9907 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
9909 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
9910 being defined and not used.
9911 * data/lalr1.cc (yyparse): Likewise.
9912 Use "if (false)" rather than "if (0)".
9914 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
9916 * TODO: Mention that we should allow NUL bytes in tokens.
9918 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
9920 * src/scan-skel.l (<<EOF>>): Don't close standard output.
9921 Problem reported by Hans Aberg.
9923 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
9925 * src/getargs.c (version): Happy new year; update overall
9926 program copyright date from 2004 to 2005.
9928 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
9929 Problem reported by Hans Aberg.
9930 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
9931 (Output file names.): Add a test for the case when standard output
9934 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
9936 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
9937 to fix an oversight in the Bison 2.0 manual.
9939 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
9941 * NEWS: Version 2.0. Reformat the existing news items since
9942 1.875, so that related items are grouped together.
9943 * configure.ac (AC_INIT): Bump version to 2.0.
9944 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
9946 * tests/torture.at (Exploding the Stack Size with Alloca): Set
9947 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
9948 otherwise, we're not testing alloca. Unfortunately there's no
9949 simple way to consult HAVE_ALLOCA here.
9951 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
9954 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
9955 hand. This avoids a warning about comparing int to size_t when
9956 GCC warnings are enabled.
9958 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
9960 * NEWS: Bison-generated parsers no longer default to using the
9961 alloca function (when available) to extend the parser stack, due
9962 to widespread problems in unchecked stack-overflow detection.
9963 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
9964 responsibility to set it to a positive value. This lets the user
9965 specify a value that is not a preprocessor constant.
9966 * data/yacc.c (YYMAXDEPTH): Likewise.
9967 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
9968 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
9969 to be a compile-time constant. However, explain the constraints on it.
9970 Also, explain the constraints on YYINITDEPTH.
9971 (Table of Symbols): Explain that alloca is no longer the default.
9972 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
9975 * doc/bison.texinfo (Location Default Action): Mention that n must
9976 be zero when k is zero. Suggested by Frank Heckenbach.
9978 2004-12-22 Akim Demaille <akim@epita.fr>
9980 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
9981 (parser::state_type, parser::semantic_type, parser::location_type):
9982 Private, not public.
9983 (parser::parse): Return ints, not bool.
9984 Returning a bool introduces a problem: 0 corresponds to false, and
9985 it seems weird to return false on success. Returning true changes
9986 the conventions for yyparse.
9987 Alternatively we could return void and send an exception.
9988 There is no clear consensus (yet?).
9989 (state_stack, semantic_stack, location_stack): Rename as...
9990 (state_stack_type, semantic_stack_type, location_stack_type): these.
9991 Private, not public.
9992 * tests/c++.at: New.
9993 * tests/testsuite.at, tests/Makefile.am: Adjust.
9995 2004-12-21 Akim Demaille <akim@epita.fr>
9997 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
9999 2004-12-21 Akim Demaille <akim@epita.fr>
10001 Don't impose std::string for filenames.
10003 * data/lalr1.cc (b4_filename_type): New.
10004 (position::filename): Use it.
10005 (parser.hh): Move the inclusion of stack.hh and location.hh below
10006 the user code, so that needed headers for the filename type can be
10008 Forward declare them before the user code.
10009 * tests/Makefile.am (check-local, installcheck-local): Pass
10010 TESTSUITEFLAGS to the TESTSUITE.
10012 2004-12-20 Akim Demaille <akim@epita.fr>
10014 Use more STL like names: my_class instead of MyClass.
10016 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
10017 (SemanticStack, SemanticType, StateStack, StateType)
10018 (TokenNumberType, Stack, Slice, Traits, Parser::location)
10019 (Parser::value): Rename as...
10020 (location_stack, location_type, rhs_number_type, semantic_stack)
10021 (semantic_type, state_stack, state_type, token_number_type, stack)
10022 (slice, traits, parser::yylloc, parser::yylval): these.
10024 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
10026 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
10028 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
10029 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10031 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
10033 Remove uses of 'short int' and 'unsigned short int'. This raises
10034 some arbitrary limits. It uses more memory but nowadays that's
10035 not much of an issue.
10037 This change does not affect the generated parsers; that's a different
10038 task, as some users will want to conserve memory there.
10040 Ideally we should use size_t to represent all object counts, and
10041 something like ptrdiff_t to represent signed differences of object
10042 counts; but that will require more code-cleanup than I have the
10043 time to do right now.
10045 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
10046 Use size_t, not int or short int, to count objects.
10047 * src/closure.c (nritemset, closure): Likewise.
10048 * src/closure.h (nritemset, closure): Likewise.
10049 * src/nullable.c (nullable_compute): Likewise.

10057 * src/output.c (prepare_rules): Likewise.
10058 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
10059 errs, reductions): Likewise.

10062 * src/tables.c (vector_number, tally, action_number,
10063 ACTION_NUMBER_MINIMUM): Likewise.
10064 * src/output.c (muscle_insert_short_int_table): Remove.
10066 2004-12-17 Akim Demaille <akim@epita.fr>
10068 * data/lalr1.cc: Extensive Doxygenation.
10069 (error_): Rename as...
10070 (error): this, since it is visible to the user.
10072 (Parser::message): Now an automatic variable from...
10073 (Parser::yyreport_syntax_error_): here.
10074 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
10076 * tests/input.at: Escape $.
10078 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
10080 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
10081 Parenthesize rhs to avoid obscure problems with mistakes like
10082 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
10083 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10084 b4_rhs_location): Likewise.
10085 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10086 b4_rhs_location): Likewise.
10088 2004-12-16 Akim Demaille <akim@epita.fr>
10090 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
10091 yacc.c: be sure to stay within yycheck_.
10092 * tests/actions.at: Re-enable C++ tests.
10094 2004-12-16 Akim Demaille <akim@epita.fr>
10096 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
10099 2004-12-16 Akim Demaille <akim@epita.fr>
10101 Use #define to handle the %name-prefix.
10103 * data/glr.c, data/yacc.c: Comment changes.
10104 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
10105 so that one can refer to yylex in the parser file, and have it
10106 renamed, as is the case with other skeletons.
10108 2004-12-16 Akim Demaille <akim@epita.fr>
10110 Move lalr1.cc internals into yy*.

10130 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
10132 Fix some problems reported by twlevo at xs4all.
10133 * src/symtab.c (symbol_new): Report an error if the input grammar
10134 contains too many symbols. This is better than calling abort() later.
10135 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
10136 (struct node, struct graph):
10137 Rename member expand to stretch. All uses changed.
10138 (struct graph): Remove member layoutalgorithm. All uses removed.

10140 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
10142 (N_STRETCH): Rename from N_EXPAND. All uses changed.
10144 2004-12-15 Akim Demaille <akim@epita.fr>
10146 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
10147 Add more Doxygen comments.
10148 (symprint_, stack_print_, reduce_print_, destruct_, pop)
10149 (report_syntax_error_, translate_): Rename as...
10150 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
10151 (yypop_, yyreport_syntax_error_, yytranslate_): this.
10153 2004-12-15 Akim Demaille <akim@epita.fr>
10155 * data/lalr1.cc (lex_): Rename as...
10157 Move the trace here.
10158 Take the %name-prefix into account.
10159 Reported by Alexandre Duret-Lutz.
10161 2004-12-15 Akim Demaille <akim@epita.fr>
10163 Simplify the C++ parser constructor.
10165 * data/lalr1.cc (debug_): Rename as...
10166 (yydebug_): so that the parser's internals are always in the yy*
10169 (b4_parse_param_decl): Remove the leading comma as it is now only
10170 called as unique argument list.
10171 (Parser::Parser): Remove the constructor accepting a location and
10172 an initial debugging level.
10173 Remove from the other ctor the argument for the debugging level.
10174 (debug_level_type, debug_level, set_debug_level): New.
10176 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
10179 2004-12-15 Akim Demaille <akim@epita.fr>
10181 Remove b4_root related material: failure experiment
10182 (which goal was to allow to derive from a class).
10184 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
10185 definitions and uses.
10187 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
10189 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
10190 not 2, since it's not portable to subtract 1 from the start of an
10191 array. The new item 0 is never set or used. All uses changed.
10193 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
10194 the default definition of YYLLOC_DEFAULT. Problem reported
10195 by Frank Heckenbach.
10197 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
10199 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
10200 the normal case and one for the error case. Just use the
10201 first one uniformly. Problem reported by Frank Heckenbach.
10202 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
10203 use exactly the same macro in both places.
10204 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
10205 so that the normal-case YYRHSLOC works for the error case too.
10207 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
10208 (YYLLOC_DEFAULT): Use the same macro as glr.c.
10209 * doc/bison.texinfo (Location Default Action): Don't claim that
10210 we have an array of locations. Use the same macro for both glr
10211 and lalr parsers. Mention YYRHSLOC. Mention what happens when
10214 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
10216 * HACKING: Update email addresses to send announcements to.

10220 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
10222 * NEWS: Version 1.875e.
10223 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
10225 * src/scan-skel.l: Include "complain.h", for "fatal".
10227 * src/relation.h (relation_print, relation_digraph):
10228 Relation sizes are of type relation_node, not size_t (this is
10229 merely a doc fix, since the two types are equivalent).
10230 (relation_transpose): Relation sizes are of type relation_node,
10232 * src/relation.c: Likewise.
10233 (top, infinity): Now of type relation_node, not int.
10234 (traverse, relation_transpose): Use relation_node, not int.
10236 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
10237 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
10238 (yyparse): Remove unused local introduced in 2004-10-25 patch.
10240 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
10241 specifying whether the test should be skipped. Use it tp
10242 specify that the [%defines %skeleton "lalr1.cc"] tests currently
10243 fail on some hosts, and should be skipped.
10245 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
10247 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
10248 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
10249 unless otherwise specified below.
10251 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
10252 to allocate kernel_base, kernel_items, kernel_size, since
10253 they needn't be initialized to 0.
10254 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
10255 * src/closure.c (new_closure): Likewise, for itemset.

10260 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
10261 * src/reader.c (packgram): Likewise, for ritem, rules.
10262 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.

10265 * src/symtab.c (symbols_token_translations_init): Likewise for
10266 token_translations.
10267 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.

10271 (goto_actions): Likewise for state_count.
10272 (pack_table): Likewise for base, pos, check.
10273 (tables_generate): Likewise for width.
10275 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
10276 for initial core. Just have a separate core, so we needn't worry
10277 about whether kernel_size and kernel_base are initialized.
10279 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
10280 kernel_size, kernel_items): Remove unnecessary initialization.
10281 * src/conflicts.c (conflicts): Likewise.
10282 * src/derives.c (derives): Likewise.

10285 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
10286 conflrow, conflict_table, conflict_list, table, check):
10289 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
10290 This is because all callers pass unsigned int.
10291 * src/closure.h (new_closure): Likewise.
10293 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
10294 (build_relations): Initialize includes[i] in all cases.
10295 * src/reader.c (packgram): Always initialize rules[ruleno].prec
10296 and rules[ruleno].precsym. Initialize members in order.
10297 * src/relation.c (relation_transpose): Always initialize new_R[i]
10299 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
10301 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
10302 conflict_list[0] was always 0, but now it isn't initialized.
10304 * src/table.c (table_grow): When conflict_table grew, the grown
10305 area wasn't cleared. Fix this.
10307 * lib/.cvsignore: Add strdup.c, strdup.h.
10308 * m4/.cvsignore: Add strdup.m4.
10310 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
10312 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
10313 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
10314 GOTO_NUMBER_MAXIMUM, since we occasionally compute
10315 ngotos + 1 without checking for overflow.
10316 (build_relations): Use END_NODE, not -1, to denote end of edges.
10317 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
10318 build_relations): Use goto_number, not int, for goto numbers.
10319 * src/tables.c (save_column, default_goto): Likewise.
10321 2004-11-23 Akim Demaille <akim@epita.fr>
10323 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
10324 of #defining from yystype.
10325 Don't typedef yystype, C++ does not need it.
10326 This lets it possible to forward declare it as union.
10328 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
10330 * bootstrap (gnulib_modules): Add extensions.
10331 Problem reported by Jim Meyering.

10336 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
10337 src/system.h, src/tables.c: XFREE -> free, to accommodate
10338 recent change to gnulib xalloc.h.
10339 Problem reported by Jim Meyering.
10341 2004-11-17 Akim Demaille <akim@epita.fr>

10345 2004-11-17 Akim Demaille <akim@epita.fr>,
10346 Alexandre Duret-Lutz <adl@gnu.org>
10348 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow

10358 2004-11-17 Akim Demaille <akim@epita.fr>
10360 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
10361 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
10362 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
10363 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
10365 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
10367 * data/glr.c (yyloc_default): Remove; not used.
10368 Problem reported by Frank Heckenbach.
10370 2004-10-25 Akim Demaille <akim@epita.fr>
10372 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
10373 Introduce another definition to address simple location arrays.
10374 (yyGLRStack): New member: yyerror_range.
10375 (yyrecoverSyntaxError, yyparse): Update it.
10376 (yyrecoverSyntaxError): Use it when shifting the error token to
10377 have an accurate range, equivalent to the one computed by both
10378 yacc.c and lalr1.cc.
10379 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
10380 that column numbers start at column 0, as per GNU Coding
10381 Standards, the others tests, and the doc.
10382 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
10383 Adjust to the above change (first column is 0).
10384 And adjust the location of the "<error>", now covering the whole
10387 2004-10-22 Akim Demaille <akim@epita.fr>
10388 and Paul Eggert <eggert@cs.ucla.edu>
10390 Remove some arbitrary limits on goto numbers and relations.
10391 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
10392 initial values, since they're never used.
10393 (set_goto_map): ngotos is now unsigned, so test for overflow
10394 by seeing whether it wraps around to zero.
10395 * src/lalr.h (goto_number): Now size_t, not short int.
10396 (GOTO_NUMBER_MAXIMUM): Remove.
10397 * src/relation.c (relation_print, traverse, relation_transpose):
10398 Check for END_NODE rather than looking at sign.
10399 * src/relation.h (END_NODE): New macro.
10400 (relation_node): Now size_t, not short int.
10402 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
10404 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
10405 keyword, not an identifier. Problem reported by Baron Schwartz in
10406 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
10408 2004-10-11 Akim Demaille <akim@epita.fr>
10410 * src/symtab.c (symbol_check_alias_consistency): Also check
10411 type names, destructors, and printers.
10412 Reported by Alexandre Duret-Lutz.
10413 Recode the handling of associativity and precedence in terms
10414 of symbol_precedence_set.
10415 Accept no redeclaration at all, not even equal to the previous
10417 (redeclaration): New.
10418 Use it to factor redeclaration complaints.
10419 (symbol_make_alias): Don't set the type of the alias, let
10420 symbol_check_alias_consistency do it as for other features.
10421 * src/symtab.h (symbol): Add new member prec_location, and
10423 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
10424 * tests/input.at (Incompatible Aliases): New.
10426 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
10428 .cvsignore fixes to accommodate gnulib changes,
10429 and the practice of naming build directories "_build".
10430 * .cvsignore: Add "_*". Sort.
10431 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
10432 * m4/.cvsignore: Add "*_gl.m4".
10434 2004-10-06 Akim Demaille <akim@epita.fr>
10436 * src/parse-gram.y (add_param): Fix the truncation of trailing
10439 2004-10-05 Akim Demaille <akim@epita.fr>
10441 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
10442 whether the reducion was empty or not. This leaves room to
10443 improve the use of YYLLOC_DEFAULT in such a case.
10444 lalr1.cc is still experimental, so changing this is acceptable.
10445 And finally, there are probably not many users who changed the
10446 handling of locations in GLR, so changing is admissible too.
10448 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
10449 empty reduction, set @$ to an empty location ending the previously
10451 Adjust uses to make sure the code is triggered on empty
10453 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
10454 expected output: empty reductions have empty locations.
10456 2004-09-29 Akim Demaille <akim@epita.fr>
10458 * data/lalr1.cc: Move towards a more standard C++ coding style
10459 for templates: Class < T > -> Class<T>.
10461 2004-09-29 Akim Demaille <akim@epita.fr>
10463 * data/lalr1.cc: Reinstall the former ctor, for sake of
10464 compatibility, but warn it will be removed.
10465 Move towards a more standard C++ coding style (i.e., type *var ->
10468 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
10470 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
10471 since it's less likely to work if NULs are involved in the future.
10473 2004-09-27 Akim Demaille <akim@epita.fr>
10475 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
10477 2004-09-27 Akim Demaille <akim@epita.fr>
10479 * data/lalr1.cc (b4_parse_param_decl_1): New.
10480 (b4_parse_param_decl): Use it to have different names between attribute
10481 and argument names.
10482 (b4_cc_constructor_call): Likewise.
10484 2004-09-24 Akim Demaille <akim@epita.fr>
10486 * src/parse-gram.y (add_param): Strip the leading and trailing
10487 blanks from a formal argument declaration.
10488 (YY_LOCATION_PRINT): New.
10490 2004-09-24 Akim Demaille <akim@epita.fr>
10492 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
10493 after the location.
10495 2004-09-24 Akim Demaille <akim@epita.fr>
10497 * doc/bison.texinfo (Table of Symbols): Sort.
10499 2004-09-21 Akim Demaille <akim@epita.fr>
10501 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
10502 the useless parentheses.
10503 Suggested by Paul Eggert.
10505 2004-09-20 Akim Demaille <akim@epita.fr>
10507 Let the initial-action act on the look-ahead, and use it for the
10508 "initial push" (corresponding to an hypothetical beginning-of-file).
10509 And let lalr1.cc honor %initial-action.
10511 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
10513 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
10514 (Parser::Parser): Remove the ctor that used to initialize it.
10515 (Parser::parse): Like in the other skeletons, issue the "starting
10516 parse" message before any action.
10517 Honor %initial-action.
10518 Initialize the stacks with the lookahead.
10519 * data/yacc.c: Let $$ and @$ in %initial-action designate the
10521 Push them in the stacks.
10522 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
10524 2004-09-20 Akim Demaille <akim@epita.fr>
10526 * doc/bison.texinfo (Initial Action Decl): New.
10528 2004-09-20 Akim Demaille <akim@epita.fr>
10530 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
10531 clearer criterion to define it.
10532 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
10533 When reducing on an empty RHS, use the latest stacked location as
10535 yylloc is not always available.
10536 * data/glr.c: Likewise.
10537 Also, honor initial-actions.
10539 2004-09-20 Akim Demaille <akim@epita.fr>
10541 * data/yacc.c (YY_LOCATION_PRINT): New.
10542 Define when we know YYLTYPE's structure, i.e., when the default
10543 YYLLOC_DEFAULT is used.
10544 * data/c.m4 (b4_yysymprint_generate): Use it.
10545 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
10546 value of the result.
10547 (error_start_): Replace with...
10548 (error_range_): this location array.
10549 This allows to replace code relying on the implementation of
10550 locations by portable code.
10551 * data/yacc.c (yylerrsp): Replace with...
10552 (yyerror_range): this.
10553 Every time a token is popped, update yyerror_range[0], to have an
10554 accurate location for the error token.
10555 * data/glr.c (YY_LOCATION_PRINT): New.
10556 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
10557 deference a pointer.
10558 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
10559 report the location in %printers.
10561 * src/scan-skel.l: Instead of abort, report error messages to ease
10562 understanding skeleton scanning failures.
10564 2004-09-16 Akim Demaille <akim@epita.fr>
10566 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
10567 (iterator, const_iterator): these, to be more in the C++ spirit.
10568 Also, return reverse iterators so that when displaying the stack
10569 we display its bottom first.
10570 (Parser::stack_print_, Parser::reduce_print_): Match the messages
10572 We should probably use vector here though.
10574 2004-09-16 Akim Demaille <akim@epita.fr>
10576 Have more complete shift traces.
10578 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
10579 to report Shifts instead of ad hoc YYDPRINTF invocations,
10580 including for the error token.
10581 * data/lalr1.cc (symprint_): Output the location.
10582 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
10583 output the location within the %printer.
10584 Activate GLR tests, at least to make sure they compile properly.
10585 They still don't pass though.
10586 * tests/calc.at: Adjust expect verbose output, since now "Entering
10587 state..." is on a different line than the "Shifting" message.
10589 2004-09-08 Akim Demaille <akim@epita.fr>
10591 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
10592 Bison directive from the Bison file to the invocation of this
10593 macro, so that these directives are passed to
10594 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10595 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10596 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10597 the extra Bison directives instead of the whole series.
10598 Change the grammar so that there are recoverable errors, and
10599 unrecoverable errors. Now we can have the parser give up before
10600 consuming the whole input. As a result we now can observe that
10601 the lookahead is freed when needed.
10602 Change the parser source to parse argv[1] instead of a hard coded
10604 Simplify yylex, and give a value and location to EOF.
10605 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10606 passed directives already coded in the file.
10607 Add some tests to check the location of "error".
10608 For some tests, the C++ parser is correct, and not yacc.c.
10609 For other tests, they provide different, but unsatisfying, values,
10610 so keep the C++ value so that at least one parser is "correct"
10611 according to the test suite.
10612 (Actions after errors): Remove, this is subsumed by the
10613 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
10615 2004-09-06 Akim Demaille <akim@epita.fr>
10617 * data/lalr1.cc: Adjust the indentation of the labels.
10618 (Parser::pop): New.
10621 2004-09-06 Akim Demaille <akim@epita.fr>
10623 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
10624 argument, an informative message.
10625 Call YY_SYMBOL_PRINT.
10626 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
10627 * data/lalr1.cc (destruct_): Likewise.
10628 In addition, no longer depend on b4_yysymprint_generate and
10629 b4_yydestruct_generate to generate these functions, do it "by
10632 2004-09-03 Akim Demaille <akim@epita.fr>
10634 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
10635 invoked, yydestruct the lookahead.
10636 * tests/calc.at (Calculator $1): Update the expected lengths of
10637 traces: there is an added line for the discarded lookahead.
10638 * doc/bison.texinfo (Destructor Decl): Some rewording.
10639 Define "discarded" symbols.
10641 2004-09-02 Akim Demaille <akim@epita.fr>
10643 * data/lalr1.cc (translate_, destruct_): No reason to be static.
10645 2004-09-02 Akim Demaille <akim@epita.fr>
10647 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
10648 (YYDSYMPRINTF): Rename as...
10649 (YY_SYMBOL_PRINT): this.
10650 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
10652 Use it instead of direct symprint_ calls.
10653 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
10656 2004-09-02 Akim Demaille <akim@epita.fr>
10658 * data/lalr1.cc (b4_yysymprint_generate): New.
10659 (symprint_): New member function, defined when YYDEBUG.
10660 Use it consistently instead of token/nterm debugging output by
10662 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
10663 %printer calls to use cdebug_ when using lalr1.cc.
10665 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
10667 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
10668 with #ifdef YYDEBUG.
10670 2004-08-26 Akim Demaille <akim@epita.fr>
10672 * doc/bison.texinfo (Implementing Loops): Rename as...
10673 (Implementing Gotos/Loops): this.
10675 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
10677 Adjust to latest gnulib.
10678 * bootstrap (gnulib_modules): Add xalloc-die.
10679 Set LC_ALL=C so that file names sort consistently.
10680 Prefer the gnulib copies of gettext.m4, glibc21.m4,
10681 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
10682 uintmax_t.m4, ulonglong.m4.
10683 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
10684 po.m4 since we are now using _gl.m4 instead.
10686 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
10688 * src/scan-action.l: Remove. Scanning of semantic actions is
10689 handled in scan-gram.l.
10691 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
10693 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
10695 * src/location.h (struct): The file member is a uniqstr.
10696 (equal_boundaries): Use UNIQSTR_EQ for comparison.
10698 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
10700 Fix bug with non-%union parsers that have printers or destructors,
10701 which led to a Bison core dump. Reported by Peter Fales in
10702 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
10704 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
10705 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
10706 not to our own type.
10707 * src/output.c (symbol_destructors_output, symbol_printers_output):
10708 Don't assume %union.
10709 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
10710 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
10711 UNION-FLAG. All callers changed.
10712 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
10713 Use type char, not unsigned int, when declaring an array of char;
10714 this lets us remove a cast.
10715 (Printers and Destructors): Add non-%union test cases.
10717 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10719 * doc/bison.texinfo: Minor editorial changes, mostly to the new
10720 GLR writeups. E.g., avoid frenchspacing and the future tense,
10721 change "lookahead" to "look-ahead", and change "wrt" to "with
10724 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10726 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
10727 New sections, split off from the GLR Parsers section. Put the new
10728 Simple GLR Parser near the start of the GLR section, for clarity.
10729 Rewrite connective text.
10731 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
10733 * doc/bison.texinfo (Simple GLR Parsers): New section.
10735 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10737 * NEWS, TODO, doc/bison.texinfo:
10738 Use "look-ahead" instead of "lookahead", to be consistent.
10739 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
10740 while we're fixing "look-ahead".
10741 * src/conflicts.c (shift_set): Renamed from shiftset.
10742 (look_ahead_set): Renamed from lookaheadset.
10743 * src/print.c: Likewise.
10744 * src/getargs.c (report_args): Add "look-ahead" as the new canonical
10745 name for "lookahead".
10746 (report_types, usage): Likewise.
10747 * src/getargs.h (report_look_ahead_tokens): Renamed from
10749 * src/lalr.c (compute_look_ahead_tokens): Renamed from
10750 compute_lookaheads.
10751 (state_look_ahead_tokens_count): Renamed from state_lookaheads_count.
10752 (look_ahead_tokens_print): Renamed from lookaheads_print.
10753 * src/state.c (state_rule_look_ahead_tokens_print): Renamed from
10754 state_rule_lookaheads_print.
10755 * src/state.h: Likewise.
10756 (reductions.look_ahead_tokens): Renamed from lookaheads.
10757 * tests/torture.at (AT_DATA_LOOK_AHEAD_TOKENS_GRAMMAR): Renamed from
10758 AT_DATA_LOOKAHEADS_GRAMMAR.
10760 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
10762 * README: Update location of patched M4 distribution.
10764 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
10766 Don't assume the C++ compiler takes the same arguments as the C compiler
10768 * configure.ac (O0CXXFLAGS): New var.
10769 * tests/atlocal.in (CXXFLAGS): Use it.
10771 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
10773 Fix some "make check" problems with C++ reported by
10774 Albert Chin-A-Young for Tru64 C++ in this thread:
10775 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
10777 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
10778 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10779 Output to a .cc file for C++, not to a .c file.
10780 * tests/calc.at (AT_CHECK_CALC): Likewise.
10781 * tests/regression.at (AT_CHECK_DANCER): Likewise.
10782 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
10784 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
10786 * tests/calc.at, tests/actions.at: Workaround for SGI
10787 C++ compiler. (trivial change)
10789 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
10791 Spent a few hours checking out which prerequisite versions the
10792 current sources actually require. I went all the way back to
10793 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
10794 a seemingly endless set of combinations of versions more recent
10795 than that. The bottom line is that the current sources require
10796 fairly recent versions of the build tools, and it'll be some work
10798 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
10799 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
10800 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
10801 Add comments explaining why those particular versions are
10804 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
10805 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
10806 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
10808 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
10809 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
10811 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
10813 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
10814 0.11.5. Suggested by Bruno Haible.

10823 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
10824 * README-alpha: Don't tell people not to package this.
10826 * bootstrap: Don't assume $(...) works; use `...` instead.
10827 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
10830 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
10831 put into the -d output file, and mention what to do if YYSTYPE is
10832 defined as a macro.
10834 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
10836 Undo change made earlier today: it caused autopoint to not bring
10837 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
10840 * bootstrap: Check that gettext version matches what's in
10841 configure.ac. Warn users to ignore robots.txt ERROR 404.
10842 * bootstrap: Undo today's earlier change (logged below).
10843 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
10845 The gettext version checking is causing more trouble than it's
10846 curing; remove it. Problem reported by Paul Hilfinger.
10848 * bootstrap: Issue a warning that one can expect a message
10849 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
10850 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
10852 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
10854 Ensure that the C++ compiler used for testing actually works on a
10855 simple test program; if not, skip the C++-related tests. Problem
10856 reported by Vin Shelton in:
10857 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html

10866 * data/glr.c (yylloc): Output this macro even if locations are not
10867 being generated, as the GLR parser needs it even in that case.
10868 Problem reported by Troy A. Johnson
10869 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
10871 * configure.ac (AC_INIT): Update to 1.875e.

10879 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
10880 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
10881 lalr1.cc runs afoul of the first, and the last two are no longer
10882 supported by GCC 3.4.0.
10883 * README: Mention GNU m4 1.4 or later; mention m4 patches.
10884 * HACKING: Use ./bootstrap, not "make update" to import foreign files.

10899 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
10900 character and string literals.
10901 (unexpected_end): New function.
10902 (unexpected_eof): Use it.

10922 * src/.cvsignore: Add *.output.
10924 * src/parse-gram.y: Put copyright notice inside %{ %} so it
10925 gets copied to the output file.
10927 2004-04-28 Paul Eggert <eggert@twinsun.com>
10929 Get files from the gnulib and po repositories, instead of relying
10930 on them being in our CVS. Upgrade to latest versions of gnulib
10933 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
10934 * bootstrap: Bootstrap from gnulib and po repositories.
10935 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
10936 * README-cvs: Document these changes. Remove version numbers from
10937 mentions of build tools, since they change so often. Mention Flex.
10939 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
10940 (gl_USE_SYSTEM_EXTENSIONS): Add.
10941 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
10942 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
10944 (AC_ISC_POSIX): Remove; we no longer support this
10945 ancient OS, as it gets in the way of latest Autoconf & gnulib.
10946 (AC_HEADER_STDC): Remove: we now assume C89 or better.
10947 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
10948 Do not check for C89 headers, except for locale.h which is used
10949 by the Yacc library and must port to K&R hosts.

10951 Do not check for C89 functions, except for setlocale which is
10952 used by the Yacc library.

10958 AM_GNU_GETTEXT): Remove; now done by:
10959 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
10960 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
10963 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
10964 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
10965 Define to empty, as gnulib.mk will do the rest for us.

10976 (strnlen, memrchr): Remove decls; functions no longer used.
10977 Include <stpcpy.h>.

11000 Remove, as these files are now generated automatically
11001 by bootstrap or automake.
11003 * po/ChangeLog: Remove: all but one entry was a duplicate
11004 of this file, and I moved that 2000-11-02 entry here.

11023 * src/.cvsignore: Remove *_.c.
11026 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
11027 support it. (The latest stable gzip doesn't.)
11029 2004-04-27 Paul Eggert <eggert@twinsun.com>
11031 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
11032 case, as stos_ is now used by destructors due to the 2004-02-09
11035 Remove more K&R C support.
11036 * lib/libiberty.y (PARAMS): Remove. All uses removed.

11047 unconditionally. Do not declare perror.
11048 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
11051 * src/complain.c (_): Remove useless defn, as system.h defines this.
11053 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
11054 with latest obstack.h.
11055 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args

11057 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
11059 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
11060 so that this include file can stand alone.
11061 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
11062 does this now. Include subpipe.h first after config.h, to
11063 test whether it can stand alone.
11065 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
11066 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
11067 unused declaration.
11069 * tests/synclines.at (%union synch line): Put a dummy member in
11070 the union, because empty unions aren't allowed in C. Caught
11073 2004-04-13 Jim Meyering <jim@meyering.net>
11075 * src/conflicts.c (conflicts_print): Correct format string typo:

11136 Use expected_sr_conflicts in place of expected_conflicts.
11137 Warn if expected_rr_conflicts used in non-GLR parser.
11139 * doc/bison.texinfo: Add documentation for %expect-rr.
11141 2004-03-08 Paul Eggert <eggert@gnu.org>
11143 Add support for hex token numbers. Suggested by Odd Arild Olsen in
11144 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
11146 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
11148 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
11149 * src/scan-gram.l (scan_integer): New function.
11151 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
11152 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
11153 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
11154 Say "long int", not "long", for uniformity with GNU style.

11160 chatty, reported by Guido Trentalancia in
11161 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
11163 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>

11175 error_start_ when erroneous token are discarded.
11176 (Parser::parse) <yyerrlab1>: Compute the location of the error
11177 token so that it covers all the discarded tokens.
11178 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
11179 it can be called with `%skeleton "lalr1.cc"', and do that.
11181 2004-02-02 Paul Eggert <eggert@twinsun.com>
11183 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
11184 $(top_srcdir)/lib and ../lib. This fixes a bug reported
11185 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
11186 There's no need to mention top_builddir since Automake does that
11188 (INCLUDES): Remove, as Automake says it's obsolescent.
11189 Contents migrated into AM_CPPFLAGS as described above.
11190 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
11192 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>

11198 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11200 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
11201 resulting parsers are compilable with C++.
11203 2003-12-23 Paul Eggert <eggert@twinsun.com>
11205 * config/depcomp, config/install-sh: Sync with Automake 1.8.
11206 * src/output.c (output_skeleton): Rename local var.
11207 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
11208 Bison tokens, as this runs afoul of the 2003-10-07 change that
11209 disallowed NUL bytes in character constants or string literals.
11211 * tests/local.at: Require Autoconf 2.59's Autotest.
11212 * tests/testsuite.at: Don't include local.at, since we now assume
11213 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
11215 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
11216 multiple inclusion warnings.
11218 2003-12-02 Akim Demaille <akim@epita.fr>

11313 When reducing initial empty rules, Bison parser read an initial
11314 location that is not defined. This results in garbage, and that
11315 affects Bison's own parser. Therefore we need (i) to extend Bison
11316 to support a means to initialize this location, and (ii) to use
11317 this CVS Bison to fix CVS Bison's parser.

11358 Also, augment the similarity between lalr1.cc and yacc.c.
11359 Note: the locations of error recovery rules are not correct yet.
11361 * data/lalr1.cc: Comment changes to augment the similarity between
11362 lalr1.cc and yacc.c.
11363 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
11364 (yyerrlab1): Remove, but where it used to be (now the bottom part of
11365 yyerrlab), when hitting EOF, pop the whole stack here instead of
11366 merely falling thru the default error handling mechanism.
11367 (yyerrorlab): New label, with the old contents of YYERROR,
11368 plus the following change: pop the stack of rhs corresponding
11369 to the production that invoked YYERROR. That is how Yacc
11370 behaves (required by POSIX).
11371 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
11374 2003-08-25 Akim Demaille <akim@epita.fr>
11376 Tune local.at so that people can "autom4te -l autotest calc.at -o
11377 calc" for instance, to extract a sub test suite.
11379 * tests/testsuite.at: Move the initialization, Autotest version
11380 requirement, and AT_TESTED invocation into...
11381 * tests/local.at: here.
11382 * tests/testsuite.at: Include it for compatibility with Autoconf
11384 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should

11389 Rework code slightly to avoid gcc -Wtraditional warnings.
11390 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
11391 The returned value is now stored in *YY0. All callers changed.
11392 * src/output.c (merge_output): Adjust to the above change.
11394 2003-07-26 Paul Eggert <eggert@twinsun.com>
11396 * data/glr.c (YYASSERT): New macro.
11397 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
11398 yyresolveStates, yyprocessOneStack):
11399 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.

11402 2003-07-25 Paul Eggert <eggert@twinsun.com>
11404 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
11405 for portability to K&R C (after ansi2knr, presumably). See
11406 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
11407 by Frank Heckenbach, though I have omitted the structure-initialization
11408 part of his glr-knr.diff patch since I recall that the Portable
11409 C Compiler didn't require that change.

11417 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
11419 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
11421 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):

11498 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
11499 `How Can I Reset @code{yyparse}', since texinfo does not allow
11500 arbitrary @ in node names.
11502 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
11503 shouldn't be needed according to the gettext 0.12.1 documentation
11504 but which seem to be needed anyway: codeset.m4 glibc21.m4

11527 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
11528 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
11529 the tests right now.
11530 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
11531 yyerror are declared before use; C99 requires this.
11533 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11535 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
11537 (yyrecoverSyntaxError): Correct the logic for setting and testing
11539 Correct comment on handling EOF.
11540 Allow states with only a default reduction, rather than failing
11541 (I can't quite reconstruct why these were not allowed before).
11543 Fixes to avoid problem that $-N rules in GLR parsers can cause
11544 buffer overruns, corrupting state.
11546 * src/output.c (prepare_rules): Output max_left_semantic_context
11548 * src/reader.h (max_left_semantic_context): New variable declaration.

11566 to differentiate output with and without locations.
11567 Remove forward declarations of yylex and yyerror---caused errors
11568 because default YYLTYPE not yet defined.
11569 Change semantic actions to compute strings, rather than printing
11570 them directly (to test proper passing of semantics values). Change
11571 output to prefix notation and update test data and expected results.
11572 (yylex): Track locations.
11573 (stmtMerge): Return value rather than printing, and include arguments

11586 Rename local vars to avoid warnings.
11587 * tests/glr-regression.at (Improper handling of embedded actions
11588 and $-N in GLR parsers): Remove unused local variable from yylex.
11589 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
11590 (void) as arg when not pure, since we now assume C89 when building
11591 Bison. Pacify GCC by using parameter.
11593 2003-06-02 Paul Eggert <eggert@twinsun.com>
11595 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
11596 yy::Location::lines, yy::Location::columns): Rename arguments
11597 to avoid shadowing; this removes a warning generated by GCC 3.3.
11599 2003-06-01 Paul Eggert <eggert@twinsun.com>
11601 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
11602 to g++, as GCC 3.3 complains if you do it.
11603 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
11604 everything that WARNING_CFLAGS has, except omit warnings
11605 not suitable for C++.
11606 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
11607 * tests/atlocal.in (CXXFLAGS): New var.
11608 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
11610 Fix a GLR parser bug I reported in February; see
11611 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
11612 The problem was that GLR parsers did not conform to the C standard,
11613 because actions like { $1 = $2 + $3; } expanded to expressions
11614 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11615 to a local variable. The C standard says that expressions
11616 like (var = f ()) + (var = f ()) have undefined behavior.
11617 Another problem was that GCC sometimes issues warnings that
11618 yyfill and its parameters are unused.
11620 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11621 as possibly unused.
11622 (yyfill): New function.
11624 (yyuserAction): Change type of yynormal to bool, so that it matches
11625 the new yyfill signature. Mark it as possibly unused.
11628 Follow up on a bug I reported in February, where a Bison-generated
11629 parser can loop. Provide a test case and a fix for yacc.c. I
11630 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11631 The original bug report is in:
11632 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
11634 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11635 macro's size was becoming unwieldy.
11636 (yyerrlab): Do not discard an empty lookahead symbol, as this
11637 might destroy garbage.
11638 (yyerrorlab): New label, with the old contents of YYERROR,
11639 plus the following change: pop the stack of rhs corresponding
11640 to the production that invoked YYERROR. That is how Yacc
11641 behaves, and POSIX requires this behavior.
11642 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11643 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11644 Define 'alarm' to do nothing if unistd.h is not available.
11645 Add a new rule "exp: '-' error;" to test the above change to
11646 data/yacc.c. Use 'alarm' to abort any test taking longer than
11647 10 seconds, as it's probably looping.
11648 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11649 Also, the new yacc.c generates two fewer diagnostics for an
11652 2003-05-24 Paul Eggert <eggert@twinsun.com>
11654 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
11655 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
11656 This fixes a problem reported by John Bowman when the Compaq/HP
11657 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
11658 -ansi -Wall -gall).
11659 * data/yacc.c (union yyalloc): Likewise.
11660 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
11662 Switch from 'int' to 'bool' where that makes sense.
11664 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,

11688 lbitset_xor_cmp): Likewise.
11689 * lib/bbitset.h: Include <stdbool.h>.
11690 (struct bitset_vtable): The following members now return bool, not
11691 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
11692 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,

11716 * src/output.c (prepare): Use it.
11717 * src/output.c (token_definitions_output,

11721 * src/state.c (state_rule_lookaheads_print): Likewise.
11723 * config/install-sh: Sync from automake 1.7.5.
11725 2003-05-14 Paul Eggert <eggert@twinsun.com>
11727 * src/parse-gram.y (rules_or_grammar_declaration): Require a
11728 semicolon after a grammar declaration, in the interest of possible
11729 future changes to the Bison input language.
11730 Do not allow a stray semicolon at the start of the grammar.
11731 (rhses.1): Allow one or more semicolons after any rule, including
11732 just before "|" as required by POSIX.
11733 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
11736 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11738 %parse-param support for lalr1.cc.
11740 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
11741 b4_cc_constructor_calls, b4_cc_constructor_call,
11742 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
11744 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
11745 parse-param arguments.
11746 (yy::b4_parser_class_name): Declare instance variables to
11747 hold parse-param arguments.
11748 * tests/calc.at: s/value/semantic_value/ because value clashes
11749 with a member of yy::b4_parser_class_name. Adjust C++ code
11750 to handle %parse-param. Enable %parse-param test in C++.
11752 2003-05-12 Paul Eggert <eggert@twinsun.com>
11754 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
11755 English a bit. Fix fclose typo. Change "const char" to "char
11756 const", and use ANSI C rather than K&R for "main". Suggest
11757 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
11758 and suggest yy_switch_to_buffer.
11760 2003-05-05 Paul Eggert <eggert@twinsun.com>
11762 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
11763 C89. This avoids a diagnostic on compilers that define __STDC__
11764 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
11765 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11767 2003-05-03 Paul Eggert <eggert@twinsun.com>
11769 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
11770 Do not overrun array bounds.
11771 This should fix a bug reported today by Olatunji Oluwabukunmi in
11772 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
11774 2003-04-29 Akim Demaille <akim@epita.fr>
11776 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
11777 * src/getargs.c, src/getargs.h: here, as bool, not int.
11778 (nondeterministic_parser): New.
11779 * src/parse-gram.y, src/scan-gram.l: Support
11780 %nondeterministic-parser.
11781 * src/output.c (prepare): Use nondeterministic_parser instead
11782 of glr_parser where appropriate.
11783 * src/tables.c (conflict_row, action_row, save_row)
11784 (token_actions, token_actions, pack_vector): Ditto.
11786 2003-04-29 Akim Demaille <akim@epita.fr>
11788 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
11790 2003-04-29 Akim Demaille <akim@epita.fr>
11792 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
11793 with %pure-parser and %locations to exercise the patch from Yakov
11796 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
11798 * data/yacc.c: (b4_lex_param): Corrected for the case where
11799 %lex-param is provided and %pure-parser isn't.
11801 2003-04-27 Paul Eggert <eggert@twinsun.com>
11803 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
11804 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
11805 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
11806 if it is not defined.
11807 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
11809 2003-04-26 Paul Eggert <eggert@twinsun.com>
11811 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
11812 Declare to be of type suitable for the ninf value itself, not of
11813 type suitable for the corresponding table, since the latter might
11814 be unsigned but the ninf value might be negative. This fixes a
11815 bug reported by Alexandre Duret-Lutz in
11816 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
11818 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
11819 invokes it. We shouldn't invoke it twice because it will attempt
11820 to put error.o in the archive twice. This fixes a glitch reported
11821 by Martin Mokrejs in
11822 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11824 2003-04-21 Paul Eggert <eggert@twinsun.com>
11826 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
11829 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
11831 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
11832 Fix obvious typo that results in uncompilable GLR parsers
11833 when both %pure-parser and %locations are used. (trivial change)
11835 2003-04-17 Paul Eggert <eggert@twinsun.com>
11837 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
11838 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
11839 Do not insert the expected token via unput, as this runs afoul
11840 of a POSIX-compatibility bug in flex 2.5.31.
11841 All uses changed to BEGIN the parent state,
11842 since we no longer insert the expected token via unput.
11843 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
11844 that is no longer emitted after the above change.
11846 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
11847 the first one. This change is from Paul Hilfinger, and it fixes
11848 regression reported by Werner Lemberg in
11849 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
11851 (resolve_sr_conflict): Don't invoke state_errs_set
11852 unless one or more tokens have been explicitly made errors.
11853 Otherwise, the above change causes Bison to abort.
11855 * tests/existing.at (GNU pic Grammar): New test case, taken from
11858 2003-03-31 Akim Demaille <akim@epita.fr>
11860 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
11862 2003-03-31 Akim Demaille <akim@epita.fr>
11864 * src/output.c (prepare_symbols): Avoid trailing spaces in the
11867 2003-03-31 Akim Demaille <akim@epita.fr>
11869 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
11870 From Paul Hilfinger.
11872 2003-03-29 Akim Demaille <akim@epita.fr>
11874 * m4/error.m4: Do not put under dynamic conditions some code which
11875 expansion is under static control.
11877 2003-03-29 Akim Demaille <akim@epita.fr>
11879 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
11881 2003-03-29 Akim Demaille <akim@epita.fr>
11883 * doc/bison.texinfo (Strings are Destroyed): New.
11885 2003-03-13 Paul Eggert <eggert@twinsun.com>
11887 * .cvsignore: Add configure.lineno.
11888 * src/.cvsignore: Add yacc.
11889 * tests/.cvsignore: Add testsuite.log.
11890 * doc/fdl.texi: Sync with latest FSF version.
11892 2003-03-12 Paul Eggert <eggert@twinsun.com>
11894 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
11895 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
11896 cursor, instead of leaving it undefined. This fixes a bug
11897 reported by Tim Van Holder in
11898 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
11899 * tests/input.at (Torturing the Scanner): Test the scanner on
11900 an empty input file, which was Tim Van Holder's test case.
11902 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
11903 <sys/resource.h> can be included, include sys/time.h and
11904 sys/times.h first, if available. This works around the SunOS
11905 4.1.4 porting bug reported by Bruce Becker in
11906 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
11908 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
11909 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
11910 AC_HEADER_SYS_WAIT.
11912 Merge changes from gnulib. This was prompted because the CVS
11913 snapshot didn't build on Solaris 7 due to strnlen problems.
11915 These changes need to be merged back into gnulib:
11916 * lib/hash.c: Include <stdbool.h> unconditionally.
11917 * m4/onceonly.m4 (m4_quote): New macro.
11918 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
11919 Quote AC_FOREACH variable-expansions properly.
11920 The 2003-01-03 obstack.h change also needs merging.
11921 {end of changes requiring merging}
11923 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
11924 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
11925 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
11926 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
11927 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
11928 New files, imported from gnulib.
11929 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
11932 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
11933 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
11936 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
11938 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
11939 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
11940 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
11941 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
11942 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
11943 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
11944 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
11945 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
11946 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
11947 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
11948 (jm_PREREQ_ARGMATCH): Remove.
11949 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
11950 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
11952 * src/system.h: Include <stdbool.h> unconditionally.
11954 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
11955 assuming at least C89 in the bitset code for some time now.
11957 2003-03-03 Akim Demaille <akim@epita.fr>
11961 2003-03-02 Akim Demaille <akim@epita.fr>
11963 * doc/bison.texinfo (Table of Symbols): Reactivate the
11964 documentation for %lex-param, and %parse-param.
11966 2003-03-02 Akim Demaille <akim@epita.fr>
11968 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
11969 generate verbose error messages.
11970 Use the number of tokens as an upper bound in yytname, as it
11971 cannot be a non terminal.
11973 2003-03-02 Akim Demaille <akim@epita.fr>
11975 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
11978 2003-03-02 Akim Demaille <akim@epita.fr>
11980 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
11981 Use them to exercise yycheck overrun.
11982 Based on Andrew Suffield's grammar.
11984 2003-03-02 Akim Demaille <akim@epita.fr>
11986 Create tests/local.at for Bison generic testing macros.
11988 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
11989 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
11991 * tests/calc.at (AT_CHECK_CALC): Adjust.
11992 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
11993 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
11994 * tests/local.at: here.
11995 (AT_COMPILE_CXX): Tags the tests using it as c++.
11996 Ignore the test if CXX is not functional.
11998 2003-03-01 Paul Eggert <eggert@twinsun.com>
12000 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
12001 not loc->end, since loc->end might contain garbage and this leads
12002 to undefined behavior on some platforms.
12003 (id_loc, token_start): Use (IF_LINTed) initial values that do not
12004 depend on *loc, so that the reader doesn't give the the false
12005 impression that *loc is initialized.
12006 (<INITIAL>"%%"): Do not bother setting code_start, since its value
12007 does not survive the return.
12009 2003-03-01 Akim Demaille <akim@epita.fr>
12011 * src/scan-gram.l (code_start): Always initialize it when entering
12012 into yylex, as SC_EPILOGUE is activated *before* the corresponding
12013 yylex invocation. An alternative would be making it static, but
12014 then it starts with the second %%'s beginning, instead of its end.
12016 2003-02-28 Paul Eggert <eggert@twinsun.com>
12018 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
12019 around a UnixWare 7.1.1 porting bug reported by John Hughes in
12020 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
12022 2003-02-26 Paul Eggert <eggert@twinsun.com>
12024 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
12025 Remove Sequent/Pyramid discussion (nobody uses them any more).
12026 Merge VMS and MS-DOS discussion; these ports may well be dead
12027 but let's keep mentioning them for now. Put <> around email
12028 addresses. Add copyright notice.
12030 2003-02-24 Paul Eggert <eggert@twinsun.com>
12032 * data/glr.c (yy_reduce_print): yylineno -> yylno,
12033 to avoid collision with flex use of yylineno.
12034 Problem reported by Bruce Lilly in
12035 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
12036 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
12037 * data/yacc.c (yy_reduce_print): Likewise.
12039 * config/depcomp: Sync with Automake 1.7.3.
12041 2003-02-21 Akim Demaille <akim@epita.fr>
12043 * data/lalr1.cc: Use temporary variables instead of casts to
12044 change integer types.
12045 Suggested by Paul Eggert.
12047 2003-02-21 Akim Demaille <akim@epita.fr>
12049 * doc/bison.texinfo: Use "location" consistently to refer to @n,
12050 to avoid confusions with lalr1.cc's notion of Position.
12051 Suggested by Paul Eggert.
12053 2003-02-20 Akim Demaille <akim@epita.fr>
12055 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
12056 before initial_columns.
12057 (location.hh): Use consistent variable names when defining the
12059 Use "last" so that we subtract from Positions, not from unsigned.
12061 2003-02-20 Akim Demaille <akim@epita.fr>
12063 * data/lalr1.cc (position.hh): New subfile, including the extended
12064 and Doxygen'ed documentation of class Position.
12065 (location.hh): Use it.
12066 Document a` la Doxygen.
12067 With the help of Benoit Perrot.
12069 2003-02-20 Akim Demaille <akim@epita.fr>
12071 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
12073 Redefine AT_YYERROR_SEES_LOC_IF using it.
12074 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
12076 Don't use the location in yy::Parser::error_ and
12077 yy::Parser::print_ when not %locations.
12078 Activate more lalr1.cc tests.
12080 2003-02-19 Akim Demaille <akim@epita.fr>
12082 * data/lalr1.cc: When displaying a line number, be sure to make it
12085 2003-02-19 Akim Demaille <akim@epita.fr>
12087 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
12089 (YYABORT, YYACCEPT, YYERROR): New.
12090 * tests/calc.at: Renable the lalr1.cc test.
12092 2003-02-19 Akim Demaille <akim@epita.fr>
12094 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
12095 error recovery, mixing with/without pops and discarding of the
12098 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
12100 2003-02-17 Paul Eggert <eggert@twinsun.com>
12102 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
12103 * tests/testsuite.at (AT_COMPILE): Use them.
12104 This fixes the testsuite problem reported by Robert Lentz in
12105 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
12107 2003-02-12 Paul Eggert <eggert@twinsun.com>
12109 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
12110 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
12111 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
12112 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
12113 Check for malloc failure, for consistency with yacc.c.
12114 (yytname_size): Remove, for consistency with yacc.c.
12116 The bug still remains in data/lalr1.cc, as I didn't have time
12119 2003-02-06 Akim Demaille <akim@epita.fr>
12121 * configure.ac (GXX): Rename as...
12122 (CXX): this, to keep the original Autoconf semantics.
12124 * data/lalr1.cc: Fix b4_copyright invocations.
12125 If YYDEBUG is not defined, don't depend upon name_ being defined.
12126 (location.hh): Include string and iostream.
12127 (Position::filename): New member.
12128 (Position::Position ()): New.
12129 (operator<< (Position)): New.
12130 (operator- (Position, int)): New.
12131 (Location::first, Location::last): Rename as...
12132 (Location::begin, Location::end): these, to mock the conventional
12134 (operator<< (Location)): New.
12135 * tests/atlocal.in (CXX): New.
12136 * tests/testsuite.at (AT_COMPILE_CXX): New.
12137 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
12138 locations in a more synthetic way.
12139 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
12141 Adjust the C locations to match those from Emacs: first column is
12143 Change all the expected results.
12144 Conform to the GCS: simplify the locations when applicable.
12145 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
12146 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
12147 these CPP macros with the m4 macros new defined by...
12148 (AT_CHECK_PUSHDEFS): this, i.e.:
12149 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
12150 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
12152 (AT_CHECK_POPDEFS): Undefine them.
12153 (AT_CHECK_CALC_LALR1_CC): New.
12154 Use it for the first lalr1.cc test.
12156 2003-02-04 Akim Demaille <akim@epita.fr>
12158 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
12159 Location as is defined.
12161 2003-02-04 Akim Demaille <akim@epita.fr>
12163 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
12164 name_ being defined.
12166 2003-02-03 Paul Eggert <eggert@twinsun.com>
12168 * src/gram.h (start_symbol): Remove unused decl.
12170 Use more-consistent naming conventions for local vars.
12172 * src/derives.c (derives_compute): Change type of local var from
12173 int to rule_number.
12174 * src/gram.c (grammar_rules_partial_print): Likewise.
12175 * src/print.c (print_core): Likewise.
12176 * src/reduce.c (reduce_grammar_tables): Likewise.
12178 * src/gram.c (grammar_dump): Change name of item_number *
12179 local var from r to rp.
12180 * src/nullable.c (nullable_compute): Likewise.
12182 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
12184 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
12185 for symbol or symbol_number var.
12186 * src/reader.c (grammar_start_symbol_set): Likewise.
12187 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
12189 * src/state.c (transitions_to): Likewise.
12190 * src/state.h: Likewise.
12191 * src/tables.c (symbol_number_to_vector_number): Likewise.
12193 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
12196 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
12199 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
12202 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
12203 Use str, not s, for char * var. Use ch, not c, for character var.
12204 Use size for size var.
12206 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
12208 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
12210 * src/uniqstr.h: Likewise.
12212 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
12213 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
12214 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
12215 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
12216 param to have same name as that of enum, so that we don't use
12217 "s" to stand for a non-state.
12219 2003-02-02 Akim Demaille <akim@epita.fr>
12221 * src/scan-skel.l: Scan more than one inert character per yylex
12224 2003-02-01 Paul Eggert <eggert@twinsun.com>
12228 * po/LINGUAS: Add ms.
12230 2003-01-30 Akim Demaille <akim@epita.fr>
12232 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
12234 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12236 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
12239 Changes in response to error report by S. Eken: GLR mode does not
12240 handle negative $ indices or $ indices in embedded rules correctly.
12241 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
12243 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
12244 (b4_rhs_location): Ditto.
12245 (yyfill): New function to copy from stack tree into array
12247 (yyuserAction): Modify to allow incremental move of semantic values
12248 to rhs array when in GLR mode.
12249 Define YYFILL to use in user-defined actions to fill semantic array
12251 Remove dummy use of yystack, as there is now a guaranteed use.
12252 (yydoAction): Modify to allow incremental move of semantic values
12253 to rhs array when in GLR mode.
12254 (yyresolveAction): Ditto.
12255 (yyglrShiftDefer): Update comment.
12256 (yyresolveStates): Use X == NULL for pointers, not !X.
12257 (yyglrReduce): Ditto.
12258 (yydoAction): Ditto
12260 * tests/glr-regr1.at: Rename to ...
12261 * tests/glr-regression.at: Add new regression test for the problems
12262 described above (adapted from S. Eken).
12263 Update copyright notice.
12264 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
12265 * tests/Makefile.am: Ditto.
12267 2003-01-28 Paul Eggert <eggert@twinsun.com>
12269 * data/lalr1.cc: Do not use @output_header_name@ unless
12270 b4_defines_flag is set. This fixes two bugs reported by
12272 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
12273 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
12275 2003-01-21 Paul Eggert <eggert@twinsun.com>
12277 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
12278 we don't need to worry about yyerrlab1 being reported as an
12279 "unused label" by non-GCC C compilers. The downside is that if
12280 locations are used then a couple of statements are duplicated each
12281 time YYERROR is invoked, but the upside is that the warnings
12283 (yyerrlab1): Move code to YERROR.
12284 (yyerrlab2): Remove. Change uses back to yyerrlab1.
12285 This reverts some of the 2002-12-27 change.
12287 2003-01-17 Paul Eggert <eggert@twinsun.com>
12289 * src/output.c (symbol_printers_output): Fix typo that led
12290 to core dump. Problem reported by Antonio Rus in
12291 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
12293 2003-01-13 Akim Demaille <akim@epita.fr>,
12294 Quoc Peyrot <chojin@lrde.epita.fr>,
12295 Robert Anisko <anisko_r@lrde.epita.fr>
12297 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
12298 when the stacks contain one element, as the loop would otherwise
12299 free the last state, and then use the top state (the one we just
12300 popped). This means that the initial elements will not be freed
12301 explicitly, as is the case in yacc.c; it is not a problem, as
12302 these elements have fake values.
12304 2003-01-11 Paul Eggert <eggert@twinsun.com>
12306 * NEWS: %expect-violations are now just warnings, reverting
12307 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
12308 bootstrapping problem reported by Matthias Klose; see
12309 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
12310 * src/conflicts.c (conflicts_print): Likewise.
12311 * tests/conflicts.at (%expect not enough, %expect too much,
12312 %expect with reduce conflicts): Likewise.
12313 * doc/bison.texinfo (Expect Decl): Document this. Also mention
12314 that the warning is enabled if the number of conflicts changes
12315 (not necessarily increases).
12317 * src/getargs.c (version): Update copyright year.
12319 2003-01-09 Akim Demaille <akim@epita.fr>
12321 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
12323 2003-01-08 Paul Eggert <eggert@twinsun.com>
12325 * Makefile.maint (WGETFLAGS):
12326 New macro, containing "-C off" to disable proxy caches.
12327 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
12328 (rel-check): Use $(WGET) instead of wget.
12330 2003-01-06 Paul Eggert <eggert@twinsun.com>
12332 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
12333 the GLR paper of Scott, Johnstone and Hussain.
12335 2003-01-04 Paul Eggert <eggert@twinsun.com>
12337 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
12338 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
12339 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
12340 (EXTRA_LIBRARIES): New var, for liby.a.
12341 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
12342 (EXTRA_SCRIPTS): New var, for yacc.
12344 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
12345 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
12346 Problem reported by Nelson H. F. Beebe.
12348 2003-01-03 Paul Eggert <eggert@twinsun.com>
12350 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
12351 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
12352 when compiling Bison 1.875's `bitset bset = obstack_alloc
12353 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
12355 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
12356 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
12357 grow to a huge size with typical invocation.
12359 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
12360 Use the pattern recommended by Autoconf 2.57, except also protect
12361 against double-definition.
12362 * src/system.h: Likewise.
12363 Portability issues reported by Nelson H. F. Beebe.
12365 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
12366 All uses changed. Provide a definition in both C and C++.
12367 (yytrue, yyfalse): Define even if defined (__cplusplus).
12369 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
12370 Reported by Nelson H. F. Beebe.
12372 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
12374 2003-01-02 Paul Eggert <eggert@twinsun.com>
12376 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
12377 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
12378 Bug reported by Nelson H. F. Beebe.
12380 2003-01-01 Paul Eggert <eggert@twinsun.com>
12384 2002-12-30 Paul Eggert <eggert@twinsun.com>
12386 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
12388 (<INITIAL>","): Here. This causes stray "," to be treated
12391 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
12392 last brace in braced code when not in Yacc mode, for compatibility
12393 with Bison 1.35. This resurrects the 2001-12-15 patch to
12396 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
12397 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
12399 2002-12-28 Paul Eggert <eggert@twinsun.com>
12401 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
12402 that of SYM's type. This fixes Debian bug 168069, reported by
12405 2002-12-28 Paul Eggert <eggert@twinsun.com>
12409 Switch back to the Yacc style of conflict reports, undoing some
12410 of the 2002-07-30 change.
12411 * doc/bison.texinfo (Understanding): Use Yacc style for
12412 conflict reports. Also, use new way of locating rules.
12413 * src/conflicts.c (conflict_report):
12414 Renamed from conflict_report_yacc, removing the old
12415 'conflict_report'. Translate the entire conflict report at once,
12416 so that we don't assume that "," has the same interpretation in
12418 (conflicts_output): Use Yacc-style conflict report for each state,
12419 instead of our more-complicated style.
12420 (conflicts_print): Use Yacc-style conflict report, except print
12421 the input file name when not emulating Yacc.
12422 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
12423 Conflicted Reduction, %expect not enough, %expect too much,
12424 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
12425 * tests/existing.at (GNU Cim Grammar): Likewise.
12426 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
12428 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
12429 fatal): Don't invoke fflush; it's not needed and it might even be
12430 harmful for stdout, as stdout might not be open.
12431 * src/reduce.c (reduce_print): Likewise.
12433 2002-12-27 Paul Eggert <eggert@twinsun.com>
12435 Fix a bug where error locations were not being recorded correctly.
12436 This problem was originally reported by Paul Hilfinger in
12437 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
12439 * data/yacc.c (yyparse): New local var yylerrsp, to record the
12440 top of the location stack's error locations.
12441 (yyerrlab): Set it. When discarding a token, push its location
12442 onto yylerrsp so that we don't lose track of the error's end.
12443 (yyerrlab1): Now is only the target of YYERROR, so that we can
12444 properly record the location of the action that failed. For GCC
12445 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
12446 GCC warning about yyerrlab1 being unused if YYERROR is unused.
12447 (yyerrlab2): New label, which yyerrlab now falls through to.
12448 Compute the error's location by applying YYLLOC_DEFAULT to
12449 the locations of all the symbols that went into the error.
12450 * doc/bison.texinfo (Location Default Action): Mention that
12451 YYLLOC_DEFAULT is also invoked for syntax errors.
12452 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
12453 Error locations include the locations of all the tokens that were
12454 discarded, not just the last token.
12456 2002-12-26 Paul Eggert <eggert@twinsun.com>
12458 * src/files.c: Include quote.h.
12459 (compute_output_file_names): Warn if we detect conflicting
12460 outputs to the same file. This should catch the misunderstanding
12461 exemplified by Debian Bug 165349, reported by Bruce Stephens..
12463 * src/conflicts.c (conflicts_print): If the user specifies
12464 "%expect N", report an error if there are any reduce/reduce
12465 conflicts. This is what the manual says should happen.
12466 This fixes Debian bug 130890, reported by Anthony DeRobertis.
12467 * tests/conflicts.at (%expect with reduce conflicts): New test.
12469 Don't use m4_include on relative file names, as it doesn't work as
12470 desired if there happens to be a file with that name under ".".
12472 * m4sugar/version.m4: Remove; it was included but it wasn't used.
12473 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
12474 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
12475 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
12476 * src/output.c (output_skeleton): Use full path names when
12477 specifying a file to include; don't rely on include path, as
12478 it's unreliable when the working file contains a file with
12481 2002-12-25 Paul Eggert <eggert@twinsun.com>
12483 Remove obsolete references to bison.simple and bison.hairy.
12484 Problem mentioned by Aubin Mahe in
12485 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
12486 * data/glr.c: Comment fix.
12487 * doc/bison.1: Remove references. Also, mention "yacc".
12489 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
12492 * src/parse-gram.y (declaration): Use enum "report_states" rather
12493 than its numeric value 1.
12495 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
12496 opening a new one. This fixes Debian bug 165349, reported by
12499 2002-12-24 Paul Eggert <eggert@twinsun.com>
12503 * Makefile.maint (cvs-update): Don't assume that the shell
12504 supports $(...), as Solaris sh doesn't.
12506 * src/parse-gram.y (lloc_default): Remove test for empty
12507 nonterminals at the end, since it didn't change the result.
12509 2002-12-24 Paul Eggert <eggert@twinsun.com>
12511 If the user does not define YYSTYPE as a macro, Bison now declares it
12512 using typedef instead of defining it as a macro. POSIX requires this.
12513 For consistency, YYLTYPE is also declared instead of defined.
12515 %union directives can now have a tag before the `{', e.g., the
12516 directive `%union foo {...}' now generates the C code
12517 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12518 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12519 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12520 instead of `yyltype'.
12522 `yystype' and `yyltype' are now obsolescent macros instead of being
12523 typedefs or tags; they are no longer documented and will be
12524 withdrawn in a future release.
12526 * data/glr.c (b4_location_type): Remove.
12527 (YYSTYPE): Renamed from yystype.
12528 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
12529 (struct YYLTYPE): Renamed from struct yyltype.
12530 (YYLTYPE): Renamed from yyltype.
12531 (yyltype, yystype): New (and obsolescent) macros,
12532 for backward compatibility.
12533 * data/yacc.c: Likewise.
12535 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
12536 does not specify a union tag. This is for compatibility with
12539 * src/parse-gram.y (add_param): 2nd arg is now char * not char
12540 const *, since it is now modified by stripping surrounding { }.
12541 (current_braced_code): Remove.
12542 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
12543 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
12544 trailing " {...}". Now of type <chars>.
12545 (grammar_declaration): Adjust to bundled tokens.
12546 (code_content): Remove; stripping is now done by add_param.
12547 (print_token_value): Print contents of bundled tokens.
12548 (token_name): New function.
12550 * src/reader.h (braced_code, current_braced_code): Remove.
12551 (token_name): New decl.
12553 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
12554 token_type, not braced_code code_kind. All uses changed.
12555 (SC_PRE_CODE): New state, for scanning after a keyword that
12556 has (or usually has) an immediately-following braced code.
12557 (token_type): New local var, to keep track of which token type
12558 to return when scanning braced code.
12559 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
12560 <INITIAL>"%parse-param", <INITIAL>"%printer",
12561 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
12562 instead of returning a token type immediately.
12563 (<INITIAL>"{"): Set token type.
12564 (<SC_BRACED_CODE>"}"): Use it.
12565 (handle_action_dollar, handle_action_at): Now returns bool
12566 indicating success. Fail if ! current_rule; this prevents a core dump.
12567 (handle_symbol_code_dollar, handle_symbol_code_at):
12568 Remove; merge body into caller.
12569 (handle_dollar, handle_at): Complain in invalid contexts.
12571 * NEWS, doc/bison.texinfo: Document the above.
12572 * NEWS: Fix years and program names in copyright notice.
12574 2002-12-17 Paul Eggert <eggert@twinsun.com>
12576 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
12577 Reporting, Table of Symbols): Omit mentions of %lex-param and
12578 %parse-param from the documentation for now.
12580 2002-12-15 Paul Eggert <eggert@twinsun.com>
12582 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
12583 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
12584 lookahead symbol, and which sets yychar in parser actions) and it
12585 disagreed with the Bison documentation. Bug
12586 reported by Andrew Walrond.
12588 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
12589 as the caller now does that.
12590 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
12591 (YYEMPTY): Parenthesize right hand side, since others use it.
12592 (yyparse): Don't assume that our generated code is the only code
12595 2002-12-13 Paul Eggert <eggert@twinsun.com>

12606 * po/LINGUAS: Add da.
12608 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
12609 problem with latest <getopt.h>.
12610 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
12612 * doc/fdl.texi: Upgrade to 1.2.
12613 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
12614 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
12615 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
12617 * config/install-sh: Sync with autotools.
12619 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
12620 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12621 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
12622 locations are requested.
12623 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
12624 locations are requested.
12626 2002-12-12 Paul Eggert <eggert@twinsun.com>
12628 Remove unportable casts and storage allocation tricks.
12629 While we're at it, remove almost all casts, since they
12630 usually aren't needed and are a sign of trouble.
12632 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
12634 * src/derives.c (derives_compute): Do not subtract NTOKENS from
12635 the pointer DSET returned by malloc; this isn't portable.

12637 Similarly for DERIVES.
12638 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
12639 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.

12663 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
12666 * src/muscle_tab.c (muscle_m4_output):
12667 Now inline. Return bool, not int.
12668 * src/state.c (state_compare): Likewise.
12669 * src/symtab.c (symbol_check_defined,
12670 symbol_check_alias_consistency, symbol_pack, symbol_translation,

12678 symbol_check_alias_consistency_processor, symbol_pack_processor,
12679 symbol_translation_processor, hash_symbol_comparator,
12680 hash_symbol_hasher): Likewise.
12681 * src/uniqstr.c (uniqstr_print_processor): Likewise.
12682 * src/muscle_tab.c (muscles_m4_output):
12683 Use new functions instead of casting old functions unportably.
12684 * src/state.c (state_hash_new): Likewise.
12685 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
12686 symbols_token_translations_init):
12688 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
12690 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
12691 var instead of casting to long, to avoid casts.
12692 (prepare_states): Use MALLOC rather than alloca, so that we don't
12693 have to worry about alloca.
12694 * src/state.c (state_hash_lookup): Likewise.
12696 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
12697 local var instead of casting to unsigned char, to avoid casts.
12699 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
12700 STATE_ALLOC): Remove.
12701 (transitions_new, errs_new, reductions_new, state_new): Use malloc
12702 rather than calloc, and use offsetof to avoid allocating slightly
12704 (state_new): Initialize all members.
12706 * src/state.c (state_hash): Use unsigned accumulator, not signed.
12708 * src/symtab.c (symbol_free): Remove; unused.
12709 (symbol_get): Remove cast in lhs of assignment.

12711 hashing-related ones.
12713 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
12714 (symbol_processor): Remove.
12715 (symbols_do): Remove decl; now static.
12717 * src/system.h (alloca): Remove; decl no longer needed.
12718 (<stddef.h>): Include, for offsetof.
12719 (<inttypes.>, <stdint.h>): Include if available.
12720 (uintptr_t): New type, if system lacks it.
12721 (CALLOC, MALLOC, REALLOC): New macros.
12722 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
12725 * src/tables.c (table_size): Now int, to pacify GCC.
12726 (table_grow, table_ninf_remap): Use signed table size.
12727 (save_row): Don't bother initializing locals when not needed.

12738 2002-12-09 Paul Eggert <eggert@twinsun.com>
12740 Change identifier spellings to avoid collisions with names
12741 that are reserved by POSIX.
12743 Don't use names ending in _t, since POSIX reserves them.
12744 For consistency, remove _e and _s endings -- they're weren't
12745 needed to remove ambiguity. All uses changed.
12746 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
12747 turn was just renamed from struniq_t.
12748 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
12749 which in turn was just renamed from struniq_processor_t.
12750 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

12821 value_t_as_yystype -> value_as_yystype.
12823 Don't include <errno.h> in the mainstream code, since it
12824 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
12825 * lib/get-errno.c, lib/get-errno.h: New files.
12826 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
12828 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.

12841 likewise for "STRUNIQ" and "UNIQSTR".
12842 * src/uniqstr.c: Renamed from src/struniq.c.
12843 * src/uniqstr.h: Renamed from src/struniq.h.

12854 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
12855 (N_EXPAND): Renamed from N_STRETCH.

12881 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
12884 Sort include-file uses.
12886 Reorder all include files under src to be in the order "system.h".
12887 then the ../lib include files in angle brackets (alphabetized),
12888 then the . include files in double-quotes (alphabetized). Fix
12889 dependency breakages encountered in this process, as follows:
12890 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
12891 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
12892 * src/state.h: Include "symtab.h".
12894 2002-12-08 Paul Eggert <eggert@twinsun.com>
12896 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
12897 since this causes problems when __file__ contains character
12898 sequences like "@" that are treated specially by src/scan-skel.l.
12899 Instead, just use the file's basename. This fixes the bug
12900 reported by Martin Mokrejs in
12901 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
12903 2002-12-06 Paul Eggert <eggert@twinsun.com>
12905 Add support for rules that do not have trailing semicolons, as
12906 POSIX requires. Improve the quality of locations in Bison
12909 * src/location.c: Include <quotearg.h>.
12910 (empty_location): Now const.
12911 (location_print): New function. Follow the recommendation of the
12912 GNU Coding Standards for locations that span file boundaries.
12913 * src/location.h: Do not include <quotearg.h>; no longer needed.
12914 (boundary): New type.
12915 (location_t): Use it. This allows locations to span file boundaries.
12916 All member uses changed: file -> start.file or end.file (as needed),

12918 last_line -> end.line, last_column -> end.column.
12919 (equal_boundaries): New function.
12920 (LOCATION_RESET, LOCATION_STEP): Remove.
12921 (LOCATION_PRINT): Remove. All callers changed to use location_print.
12922 (empty_location): Now const.
12923 (location_print): New decl.
12924 * src/parse-gram.y (lloc_default): New function, which handles
12925 empty locations more accurately.
12926 (YYLLOC_DEFAULT): Use it.

12943 the work. All uses removed.
12944 (scanner_cursor): New var.
12945 (adjust_location): Renamed from extend_location. It now sets
12946 *loc and adjusts the scanner cursor. All uses changed.
12947 Don't bother testing for CR.
12948 (handle_syncline): Remove location arg; now updates scanner cursor.
12949 All callers changed.
12950 (unexpected_end_of_file): Now accepts start boundary of token or
12951 comment, not location. All callers changed. Update scanner cursor,
12953 (SC_AFTER_IDENTIFIER): New state.
12954 (context_state): Renamed from c_context. All uses changed.
12955 (id_loc, code_start, token_start): New local vars.
12956 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
12957 processing of Yacc white space and equivalents here.
12958 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
12959 instead of returning ID immediately, since we need to search for
12960 a subsequent colon.
12961 (<INITIAL>"'", "\""): Save token_start.
12962 (<INITIAL>"%{", "{", "%%"): Save code_start.
12963 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
12964 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
12965 BEGIN context_state at end, not INITIAL.
12966 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
12967 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
12968 Return correct token start.
12969 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
12970 the start of a character, string or multiline comment is found.
12971 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
12972 Reduction): Adjust reported locations to match the more-precise
12973 results now expected.
12974 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
12975 * tests/reduce.at (Useless Rules, Reduced Automaton,
12976 Underivable Rules): Likewise.
12977 * tests/regression.at (Invalid inputs): No longer `expecting ";"
12978 or "|"' now that so many other tokens are allowed by the new grammar.
12980 * src/complain.h (current_file): Remove duplicate decl;
12981 current_file is now owned by files.h.
12982 * src/complain.c, src/scan-gram.l: Include files.h.
12984 2002-12-06 Paul Eggert <eggert@twinsun.com>
12986 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
12987 promotes to int; it might be unsigned int.
12988 * data/yacc.c (yy_reduce_print): Likewise.
12990 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
12991 be #defined in the prologue, not in the Bison declarations.
12992 This fixes Debian Bug 102878, reported by Shaul Karl.
12994 2002-12-02 Paul Eggert <eggert@twinsun.com>
12996 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
12997 * lib/strtoul.c: New file, from gnulib.
12998 This fixes a porting bug reported by Peter Klein in
12999 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
13001 2002-11-30 Paul Eggert <eggert@twinsun.com>
13003 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
13004 and put only a forward declaration in the prologue. This is for
13005 consistency with the other scanner helper functions.
13007 Type clashes now generate warnings, not errors, since it
13008 appears that POSIX may allow some grammars with type clashes.
13009 * src/reader.c (grammar_current_rule_check): Warn about
13010 type clashes instead of complaining.
13011 * tests/input.at (Type Clashes): Expect warnings, not complaints.
13013 Add Yacc library, since POSIX requires it.
13014 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
13015 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
13016 * lib/main.c, lib/yyerror.c: New files.
13018 gram_error can be static; it need not be extern.
13019 * src/reader.h (gram_error): Remove decl.
13020 * src/parse-gram.y (gram_error): Now static. Add static decl.
13021 (print_token_value): Omit parameter names from forward decl,
13024 2002-11-29 Paul Eggert <eggert@twinsun.com>
13026 * doc/bison.texinfo: Emphasize that yylex and yyerror must
13027 be declared before being used. E.g., one should typically
13028 declare them in the prologue. Use GNU coding style in examples.
13029 Put "const" consistently after the type it modifies. Mention
13030 that C99 supports "inline". Mention that yyerror traditionally
13033 %parse-param and %lex-param now take just one argument, the
13034 declaration; the argument name is deduced from the declaration.
13036 * doc/bison.texinfo (Parser Function, Pure Calling, Error
13037 Reporting, Table of Symbols): Document this.
13038 * src/parse-gram.y (add_param): New function.
13040 (declaration): Implement new rule for %parse-param and %lex-param.
13041 * src/scan-gram.l: "," now elicits a warning, rather than being
13042 a token; this is more compatible with byacc.
13043 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
13045 2002-11-27 Paul Eggert <eggert@twinsun.com>
13047 Rename identifiers to avoid real and potential collisions.
13049 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
13050 to avoid collision with lex macro described by Bruce Lilly in
13051 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
13052 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
13053 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
13054 * src/parse-gram.y (print_token_value): Renamed from yyprint.
13056 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
13057 The name "yycontrol" violates the name space rules, and this stuff
13058 wasn't being used anyway.
13059 (input): Remove action; this stuff wasn't being used.
13060 (gram_error): Rename local variable yylloc -> loc.
13061 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
13062 (YY_DECL): Don't use "yy" at start of local variables.
13063 All uses changed, e.g., yylloc -> loc.
13064 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
13065 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
13066 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
13067 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
13069 * src/parse-gram.y (gram_error): loc is now const *.
13070 * src/reader.h (gram_error): Likewise.
13072 2002-11-24 Paul Eggert <eggert@twinsun.com>
13076 * tests/actions.at (Actions after errors): Use an output format
13077 more similar to that of the Printers and Destructors test.
13078 Test the position of the ';' token too.
13079 (Printers and Destructors): Likewise.
13080 (Printers and Destructors: %glr-parser): Remove for now, to avoid
13081 unnecessarily alarming people when the test fails.
13083 * data/yacc.c (yyerrlab1): Move this label down, so that the
13084 parser does not discard the lookahead token if the user code
13085 invokes YYERROR. This change is required for POSIX conformance.
13087 * lib/error.c: Sync with gnulib.
13089 2002-11-22 Paul Eggert <eggert@twinsun.com>
13091 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
13092 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
13093 * lib/xmalloc.c: Likewise.
13095 2002-11-20 Paul Eggert <eggert@twinsun.com>
13097 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
13099 2002-11-20 Paul Eggert <eggert@twinsun.com>
13101 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
13102 should use `if (! x) abort ();' rather than `assert (x);', and
13103 anyway it's one less thing to worry about configuring.
13105 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
13106 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
13107 and replace all instances of assert with abort.
13108 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
13109 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
13111 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
13112 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
13113 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
13114 hash_find_entry, hash_rehash, hash_insert): Likewise.
13115 * src/conflicts.c (resolve_sr_conflict): Likewise.
13116 * src/lalr.c (set_goto_map, map_goto): Likewise.
13117 * src/nullable.c (nullable_compute): Likewise.
13118 * src/output.c (prepare_rules, token_definitions_output): Likewise.
13119 * src/reader.c (packgram, reader): Likewise.
13120 * src/state.c (state_new, state_free, state_transitions_set,
13121 state_reduction_find): Likewise.
13122 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
13123 symbol_pack): Likewise.
13124 * src/tables.c (conflict_row, pack_vector): Likewise.
13125 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
13126 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
13127 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
13128 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
13130 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
13131 (ARGMATCH_CONSTRAINT): New macro.
13132 (ARGMATCH_ASSERT): Use it.
13134 * src/system.h (verify): New macro.
13135 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
13136 rather than assert.
13137 * src/tables.c (tables_generate): Likewise.
13139 * src/struniq.c (struniq_assert): Now returns void, and aborts
13140 if the assertion is false.
13141 (struniq_assert_p): Remove.
13142 * src/struniq.h: Likewise.
13144 2002-11-18 Paul Eggert <eggert@twinsun.com>
13146 * data/glr.c (yygetLRActions): Replace `yyindex' with
13147 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
13148 This fixes the regression with Sun ONE Studio 7 cc that I reported in
13149 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
13151 2002-11-18 Akim Demaille <akim@epita.fr>
13153 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
13155 From Tim Van Holder.
13157 2002-11-17 Paul Eggert <eggert@twinsun.com>
13159 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
13160 to "SyntaxError" for consistency with my 2002-11-15 change.
13162 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
13163 not define to {}, since this breaks the common use of `YYDPRINTF
13164 ((...));' if a single statement is desired (e.g. before `else').
13165 Work around GCC warnings by surrounding corresponding calls with
13167 (yyhasResolvedValue): Remove unused function.
13168 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
13170 (yyreportSyntaxError): Renamed from yyreportParseError.
13171 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
13173 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
13174 extern when possible. Remove unused initializations.
13176 2002-11-16 Akim Demaille <akim@epita.fr>
13178 Augment the similarity between GLR and LALR traces.
13180 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
13181 (YY_REDUCE_PRINT): New.
13182 (yyparse): Use them.
13183 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
13185 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
13186 state reached after the reduction/recovery, since...
13187 (yyparse, yyprocessOneStack): Report the state we are entering in.
13189 2002-11-16 Akim Demaille <akim@epita.fr>
13191 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
13192 Add support for --trace=skeleton.
13193 * src/scan-skel.l: %option debug.
13194 Scan strings of non-@ or \n instead of character by character.
13195 (scan_skel): Handle trace_skeleton.
13197 (@output_parser_name@, @output_header_name@): ``Restore'' their
13198 support (used to be M4 macros).
13199 * data/yacc.c: Quote larger chunks, a la glr.c.
13200 * data/lalr1.cc: Likewise.
13201 The header guards are no longer available, so use some other
13202 string than `YYLSP_NEEDED'.
13204 2002-11-16 Akim Demaille <akim@epita.fr>
13206 Make the ``Printers and Destructors'' test more verbose, taking
13207 `yacc.c''s behavior as (possibly wrong) reference.
13209 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
13210 instead of fprint on stdout.
13211 Set and report the last_line of the symbols.
13212 Consistently display values and locations.
13214 2002-11-16 Paul Eggert <eggert@twinsun.com>
13216 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
13218 2002-11-15 Paul Eggert <eggert@twinsun.com>
13220 * tests/actions.at (Actions after errors): New test case.
13222 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
13223 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
13224 tests/action.at, tests/calc.at, tests/conflicts.at,
13225 tests/cxx-type.at, tests/regression.at:
13226 "parse error" -> "syntax error" for POSIX compatibility.
13227 "parsing stack overflow..." -> "parser stack overflow" so
13228 that code matches Bison documentation.
13230 2002-11-15 Akim Demaille <akim@epita.fr>
13232 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
13233 take two BRACED_CODE, not two string_content.
13234 Free the scanner's obstack when we are done.
13235 (code_content): New.
13236 * tests/calc.at: Adjust.
13237 * doc/bison.texinfo: Adjust.
13238 Also, make sure to include the `,' for these declarations.
13240 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
13242 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
13243 definition; avoids potential autoreconf problems.
13245 2002-11-15 Akim Demaille <akim@epita.fr>
13247 Always check the value returned by yyparse.
13249 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
13250 returned by yyparse.
13251 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
13253 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
13254 returned by yyparse.
13256 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13258 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
13261 2002-11-14 Paul Eggert <eggert@twinsun.com>
13263 * src/output.c (output_skeleton): Call xfopen instead of
13264 duplicating xfopen's body.
13266 Fix bugs reported by Nelson H. F. Beebe in
13267 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
13269 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
13270 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
13271 Group compiler. Instead, use "$CC -E bar.c". Include the .h
13272 file twice in the grammar, as an extra check.
13274 * tests/input.at (Torturing the Scanner): Surround the
13275 backslash-newline tests with "#if 0", to make it less likely that
13276 we'll run into compiler bugs. Bring back solitary \ inside
13277 comment, but add a closing comment to work around HP C bug. Don't
13278 test backslash-newline in C character constant.
13280 2002-11-14 Akim Demaille <akim@epita.fr>
13282 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
13283 status of the compiler.
13284 Calling `exit 1' is no longer needed.
13285 Reported by Nelson H. F. Beebe.
13287 2002-11-14 Akim Demaille <akim@epita.fr>
13289 * tests/atlocal.in (CPPFLAGS): We have config.h.
13290 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
13292 * tests/actions.at, tests/calc.at, tests/conflicts.at,
13293 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
13294 * tests/regression.at, tests/torture.at: Use them for all the
13295 grammars that are to be compiled.
13296 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
13297 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
13298 * doc/bison.texinfo (GLR Parsers): Document `inline'.
13300 2002-11-14 Akim Demaille <akim@epita.fr>
13302 * doc/bison.texinfo: Various formatting changes (alignments in
13303 samples, additional @group/@end group, GCS in samples.
13304 Use @deffn instead of simple @table to define the directives,
13305 macros, variables etc.
13307 2002-11-13 Paul Eggert <eggert@twinsun.com>
13309 Fix some bugs reported by Albert Chin-A-Young in
13310 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
13312 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
13313 -o c"; the HP C compiler chatters during compilation.
13314 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
13315 * tests/headers.at (export YYLTYPE): Likewise.
13317 * tests/input.at (Torturing the Scanner): Remove lines containing
13318 solitary backslashes, as they tickle a bug in the HP C compiler.
13320 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
13321 comments, since they're not portable. Use GNU coding style.
13323 2002-11-13 Akim Demaille <akim@epita.fr>
13325 * data/yacc.c: Leave bigger chunks of quoted text.
13326 (YYDSYMPRINTF): New.
13327 Use it to report symbol activities.
13328 * data/glr.c (YYDSYMPRINTF): New.
13331 2002-11-12 Paul Eggert <eggert@twinsun.com>
13335 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
13336 (yyglrReduce): Return yyok, not 0.
13337 This should avoid the enumerated-type warnings reported
13338 by Nelson H. F. Beebe in
13339 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
13341 * lib/bbitset.h (BITSET_INLINE): Remove.
13342 * lib/bitset.h [! BITSET_INLINE]: Remove.
13343 (bitset_set, bitset_reset, bitset_test): Rename local vars
13344 to avoid shadowing warnings by GCC.
13346 * data/glr.c (inline): Remove #define. It's the user's
13347 responsibility to #define it away, just like 'const'.
13348 This fixes one of the bugs reported by Nelson H. F. Beebe in
13349 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
13351 * Makefile.maint (po-check): Scan .l and .y files instead of the
13352 .c and the .h files that they generate. This fixes the bug
13353 reported by Tim Van Holder in:
13354 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
13355 Look for N_ as well as for _. Try to avoid matching #define for
13357 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
13358 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
13359 * src/scan-gram.l: Revamp regular expressions so that " and '
13360 do not confuse xgettext.
13362 * src/struniq.h (struniq_new): Do not declare the return type
13363 to be 'const'; this violates the C standard.
13364 * src/struniq.c (struniq_new): Likewise.
13366 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
13368 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
13369 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
13372 2002-11-12 Akim Demaille <akim@epita.fr>
13374 * Makefile.maint: Sync with Autoconf:
13375 (local_updates): New.
13377 2002-11-12 Akim Demaille <akim@epita.fr>
13379 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
13381 2002-11-12 Akim Demaille <akim@epita.fr>
13383 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
13386 2002-11-12 Akim Demaille <akim@epita.fr>
13388 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
13391 2002-11-12 Akim Demaille <akim@epita.fr>
13393 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
13394 Use it to test the GLR parser.
13396 2002-11-12 Akim Demaille <akim@epita.fr>
13398 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
13400 * data/glr.c (yystos): New.
13401 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
13402 (YYDSYMPRINT): New.
13403 (yyval): Don't define it, it is handled via M4.
13404 (yyrecoverParseError): Free verbosely the discarded symbols.
13405 * data/yacc.c (yysymprint): Remove, rather...
13406 (b4_yysymprint_generate): invoke.
13407 * data/c.m4 (b4_yysymprint_generate): New.
13408 Accept pointers as arguments, as opposed to the version from
13410 (b4_yydestruct_generate): Likewise.
13411 * tests/cations.at (Printers and Destructors): Use Bison directives
13412 instead of CPP macros.
13413 Don't rely on internal details.
13415 2002-11-12 Akim Demaille <akim@epita.fr>
13417 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
13418 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
13419 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
13420 it against YYEMPTY and so forth), work on yytoken (i.e., set
13421 it to YYEMPTY etc.).
13422 (yydestruct): Replace with a b4_yydestruct_generate invocation.
13423 (b4_symbol_actions): Remove.
13424 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
13425 for 0, end-of-input.
13427 2002-11-12 Akim Demaille <akim@epita.fr>
13429 * doc/bison.texinfo (Destructor Decl): New.
13431 2002-11-12 Akim Demaille <akim@epita.fr>

13512 Revamp to fix many (but not all) of the C- and M4-related quoting
13513 problems. Among other things, this fixes the Bison bug reported
13514 by Jan Hubicka when processing the Bash grammar; see:
13515 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
13517 Use new @ escapes consistently. Represent brackets with @{ and @}
13518 rather than @<:@ and @:>@, since this works a bit better with dumb
13519 editors like vi. Represent @ with @@, since @ is now consistently
13520 an escape. Use @oline@ and @ofile@ rather than __oline__ and
13521 __ofile__, to avoid unexpected expansions. Similarly, use @output
13522 rather than #output.
13524 * data/c.m4 (b4_copyright): Omit file name from comment, since
13525 the file name could contain "*/".
13526 (b4_synclines_flag): Don't quote the 2nd argument; it should already
13527 be quoted. All uses changed.
13529 * data/glr.c: Use new @ escapes consistently.
13530 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
13531 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
13532 Remove, since they couldn't handle arbitrary characters in file
13534 * data/lalr1.cc: Likewise.
13535 * data/yacc.c: Likewise.
13537 * src/files.c (output_infix): Remove; all uses removed.
13538 * src/files.h: Likewise.
13540 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
13541 mishandled funny characters in file names, and anyway it isn't
13543 * data/yacc.c: Likewise.
13544 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
13546 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
13547 * data/yacc.c: Likewise.
13549 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
13551 (muscle_init): Quote filename as a C string.
13552 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
13553 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
13554 * src/output.c (escaped_file_name_output): New function.
13555 (prepare_symbols): Quote tokens for M4.
13556 (prepare): Don't insert output_infix, output_prefix,
13557 output_parser_name, output_header_name; this is now down by scan-skel.
13558 Insert skeleton as a C string.
13560 * src/output.c (user_actions_output, symbol_destructors_output,
13561 symbol_printers_output): Quote filenames for C and M4.
13562 * src/reader.c (prologue_augment, epilogue_set): Likewise.
13564 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
13565 escapes other than \\ and \'; this simplifies the code.
13566 (<SC_STRING>): Likewise, for \\ and \".
13567 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
13568 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
13569 Use new escapes @{ and @} for [ and ].
13571 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
13572 them with auto vars.
13573 Switch to new escape scheme, where @ is the escape character uniformly.
13574 Abort if a stray escape character is found. Avoid unbounded input
13575 buffer when parsing non-escaped text.
13577 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
13578 __oline__, #output, $@, and @{ do not have unintended meanings.
13580 2002-11-09 Paul Eggert <eggert@twinsun.com>
13582 Fix the test failure due to GCC warnings described in
13583 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
13584 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
13585 evaluate to 0 if it's impossible for NINF to be in the respective
13587 (yygetLRActions, yyrecoverParseError): Use them.
13589 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
13590 counted in the token inserted at end of file. Now takes
13591 location_t *, not location_t, so that the location can be
13592 adjusted. All uses changed.
13594 * tests/regression.at (Invalid inputs): Adjust wording in
13595 diagnostic to match the new behavior.
13597 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
13598 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
13599 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
13600 abort ();'. This reduces the runtime of the "Many lookaheads"
13601 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
13604 2002-11-07 Paul Eggert <eggert@twinsun.com>
13606 * src/parse-gram.y (CHARACTER): Remove unused token.
13609 * src/scan-gram.l: Remove stack option. We no longer use the
13610 stack, since the stack was never deeper than 1; instead, use the
13611 new auto var c_context to record the stacked value.
13613 Remove nounput option. At an unexpected end of file, we now unput
13614 the minimal input necessary to end cleanly; this simplifies the
13617 Avoid unbounded token sizes where this is easy.
13619 (unexpected_end_of_file): New function.
13620 Use it to systematize the error message on unexpected EOF.
13621 (last-string): Now auto, not static.
13622 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
13623 (scanner_last_string_free): Remove; not used.
13624 (percent_percent_count): Move decl to just before use.
13625 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
13626 not the (never otherwised-used) CHARACTER.
13628 2002-11-07 Akim Demaille <akim@epita.fr>

13634 Use it when calling yyerror.
13635 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

13648 * src/output.c (symbol_printers_output)
13649 (symbol_destructors_output): Quote the file name.

13680 * src/tables.c (matching_state): Don't allow states to match if
13681 either has GLR conflict entries.
13683 2002-11-05 Paul Eggert <eggert@twinsun.com>
13685 * src/scan-gram.l: Use more accurate diagnostics, e.g.
13686 "integer out of range" rather than "invalid value".
13687 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
13690 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
13691 Also, remove one static variable in the scanner.
13693 * src/scan-gram.l (braces_level): Now auto, not static.
13694 Initialize to zero if the compiler is being picky.
13695 (INITIAL): Clear braces_level instead of incrementing it.
13696 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,

13708 * Makefile.maint: Update from Autoconf.
13709 (update, cvs-update, po-update, do-po-update): New.

13848 * src/output.c (prepare_symbols): When printing token names,
13849 escape "[" as "@<:@" and likewise for "]".
13851 * src/system.h (errno): Remove declaration, as we are now
13852 assuming C89 or better, and C89 guarantees errno.
13854 2002-10-30 Paul Eggert <eggert@twinsun.com>
13856 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
13857 Check for close failures.
13858 * src/files.h (xfclose): Return void, not int, since it always
13860 * src/files.c (xfclose): Likewise. Report I/O error if ferror
13862 * src/output.c (output_skeleton): Use xfclose rather than fclose
13863 and ferror. xfclose now checks ferror.
13865 * data/glr.c (YYLEFTMOST_STATE): Remove.
13866 (yyreportTree): Use a stack-based leftmost state. This avoids
13867 our continuing battles with bogus warnings about initializers.

13886 we use malloc. Don't assume 'A' through 'Z' are contiguous.
13887 Don't assume strdup exists; POSIX says its an XSI extension.
13888 Check for buffer overflow on input.
13890 2002-10-24 Akim Demaille <akim@epita.fr>
13892 * src/output.c (output_skeleton): Don't disable M4sugar comments
13893 too soon: it results in comments being expanded.

13899 * data/yacc.c (m4_int_type): New.
13900 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
13901 char' as only yacc.c wants K&R portability.
13902 * data/glr.c (yysigned_char): Remove.
13903 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
13904 Reported by Quoc Peyrot.
13906 2002-10-23 Paul Eggert <eggert@twinsun.com>
13908 * src/main.c (main): With --trace=time, report times even if a
13909 non-fatal error occurs. Formerly, the times were reported in some
13910 such cases but not in others.
13911 * src/reader.c (reader): Just return if a complaint has been issued,
13912 instead of exiting, so that 'main' can report times.
13914 2002-10-22 Akim Demaille <akim@epita.fr>
13916 * src/system.h: Include sys/types.
13917 Reported by Bert Deknuydt.
13919 2002-10-23 Paul Eggert <eggert@twinsun.com>
13921 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
13922 Suggested by Art Haas.
13924 2002-10-22 Paul Eggert <eggert@twinsun.com>
13926 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
13927 decl; not needed any more.
13928 * src/main.c (main): Use return to exit, undoing yesterday's change.
13929 The last OS that we could find where this wouldn't work is
13930 SunOS 3.5, and that's too old to worry about now.
13932 * data/glr.c (struct yyltype): Define members even when not
13933 doing locations. This is more consistent with yacc.c, and it
13934 works around the following bug reports:
13935 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
13936 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
13938 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
13939 @acronym consistently. Standardize on "Yacc" instead of "YACC",
13940 "Algol" instead of "ALGOL". Give a bit more history about BNF.
13942 2002-10-22 Akim Demaille <akim@epita.fr>
13944 * data/README: New.
13946 2002-10-21 Paul Eggert <eggert@twinsun.com>
13948 Be consistent about 'bool'; the old code used an enum in one
13949 module and an int in another, and this violates the C standard.
13950 * m4/stdbool.m4: New file, from coreutils 4.5.3.
13951 * configure.ac (AC_HEADER_STDBOOL): Add.
13952 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
13953 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
13954 * src/symtab.c (hash_compare_symbol_t): Likewise.
13955 * src/system.h (bool, false, true): Use a definition consistent
13956 with ../lib/hash.c. All uses changed.
13958 * src/complain.c (warning_issued): Renamed from warn_message_count,
13959 so that we needn't worry about integer overflow (!).
13960 Now of type bool. All uses changed.
13961 (complaint_issued): Renamed from complain_message_count; likewise.
13963 * src/main.c (main): Use exit to exit with failure.
13965 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
13966 rather than 1 and 0.
13967 * src/main.c (main): Likewise.
13968 * src/getargs.c (getargs): Likewise.
13969 * src/reader.c (reader): Likewise.
13971 * src/getarg.c (getargs): Remove duplicate code for
13972 "Try `bison --help'".
13974 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
13975 What was that "2" for?
13977 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
13978 * src/getargs.c (usage): Likewise.
13980 * src/getargs.c (getargs): When there are too few operands, report
13981 the last one. When there are too many, report the first extra
13982 one. This is how diffutils does it.
13984 2002-10-20 Paul Eggert <eggert@twinsun.com>
13986 Remove K&R vestiges.
13987 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
13988 * src/complain.c (VA_START): Remove. Assume prototypes.
13989 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
13990 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
13991 fatal): Assume prototypes.
13992 * src/complain.h: Assume prototypes.
13993 * src/system.h (PARAMS): Remove.
13994 Include <limits.h> unconditionally, since it's guaranteeed even
13995 for a freestanding C89 compiler.
13996 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
13997 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
13999 2002-10-20 Akim Demaille <akim@epita.fr>
14001 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
14002 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
14003 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
14004 (yyresolveStates, yyresolveAction, yyresolveStack)
14005 (yyprocessOneStack): Use them.
14006 (yy_reduce_print): New.
14007 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
14009 2002-10-20 Akim Demaille <akim@epita.fr>
14011 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
14012 arguments and output `void'.
14013 (b4_c_function): Rename as...
14014 (b4_c_function_def): this.
14015 (b4_c_function_decl, b4_c_ansi_function_def)
14016 (b4_c_ansi_function_decl): New.
14017 Change the interpretation of the arguments: before `int, foo', now
14019 * data/yacc.c (yyparse): Prototype and define thanks to these.
14020 Adjust b4_c_function_def uses.
14021 * data/glr.c (yyparse): Likewise, but ANSI only.
14023 2002-10-20 Akim Demaille <akim@epita.fr>
14025 * src/output.c (prepare): Move the definition of `tokens_number',
14026 `nterms_number', `undef_token_number', `user_token_number_max'
14028 (prepare_tokens): Here.
14029 (prepare_tokens): Rename as...
14030 (prepare_symbols): this.
14031 (prepare): Move the definition of `rules_number' to...
14032 (prepare_rules): here.
14033 (prepare): Move the definition of `last', `final_state_number',
14034 `states_number' to...
14035 (prepare_states): here.
14036 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
14038 2002-10-20 Akim Demaille <akim@epita.fr>
14040 * src/tables.h, src/tables.c, src/output.c: Comment changes.
14042 2002-10-20 Akim Demaille <akim@epita.fr>
14044 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
14047 2002-10-20 Akim Demaille <akim@epita.fr>
14049 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
14050 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
14052 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
14054 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
14055 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
14058 2002-10-19 Paul Eggert <eggert@twinsun.com>
14060 Do not create a temporary file, as that involves security and
14061 cleanup headaches. Instead, use a pair of pipes.
14062 Derived from a suggestion by Florian Krohm.
14063 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
14064 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
14065 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
14066 (BISON_PREREQ_SUBPIPE): Add.
14067 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
14068 Add subpipe.h, subpipe.c.
14069 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
14070 * po/POTFILES.in: Add lib/subpipe.c.
14071 * src/output.c: Include "subpipe.h".
14072 (m4_invoke): Remove decl.
14073 (scan_skel): New decl.
14074 (output_skeleton): Use pipe rather than temporary file for m4 input.
14075 Check that m4sugar.m4 is readable, to avoid deadlock.
14076 Check for pipe I/O error.
14077 * src/scan-skel.l (readpipe): Remove decl.
14078 (scan_skel): New function, to be used in place of m4_invoke.
14079 Read from stream rather than file.
14081 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
14082 float, as this generates a warning on Solaris 8 + GCC 3.2 with
14083 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
14084 this generates a more-accurate value anyway.
14086 * lib/timevar.c (timervar_accumulate): Rename locals to
14087 avoid confusion with similarly-named more-global.
14088 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
14090 * src/output.c (prepare): Use xstrdup to convert char const *
14091 to char *, to avoid GCC warning.
14093 2002-10-19 Akim Demaille <akim@epita.fr>
14095 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
14096 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
14097 Use them to have `calc.y' ready for %pure-parser.
14098 * data/yacc.c (YYLEX): Pass a yylex return type to
14099 b4_c_function_call.
14101 2002-10-19 Akim Demaille <akim@epita.fr>
14103 Prototype support of %lex-param and %parse-param.
14105 * src/parse-gram.y: Add the definition of the %lex-param and
14106 %parse-param tokens, plus their rules.
14107 Drop the `_' version of %glr-parser.
14109 * src/scan-gram.l (INITIAL): Scan them.
14110 * src/muscle_tab.c: Comment changes.
14111 (muscle_insert, muscle_find): Rename `pair' as `probe'.
14112 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
14113 (muscle_entry_s): The `value' member is no longer const.
14114 Adjust all dependencies.
14115 * src/muscle_tab.c (muscle_init): Adjust: use
14116 MUSCLE_INSERT_STRING.
14117 Initialize the obstack earlier.
14118 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
14119 (muscle_pair_list_grow): New.
14120 * data/c.m4 (b4_c_function_call, b4_c_args): New.

14122 * tests/calc.at: Use %locations, not --locations.
14123 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
14125 2002-10-19 Akim Demaille <akim@epita.fr>
14127 * src/getargs.c (usage): Take status as argument and exit
14129 Report the traditional `Try ... --help' message when status != 0.
14130 (usage, version): Don't take a FILE * as arg, it is pointless.
14131 (getargs): When there is an incorrect number of arguments, make it
14132 an error, and report it GNUlically thanks to `usage ()'.
14134 2002-10-18 Paul Eggert <eggert@twinsun.com>
14136 * data/glr.c (yyreportParseError): Don't assume that sprintf
14137 yields the length of the printed string, as this is not true
14138 on SunOS 4.1.4. Reported by Peter Klein.
14140 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
14141 * tests/conflicts.at (%nonassoc and eof): Likewise.
14142 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
14144 2002-10-17 Akim Demaille <akim@epita.fr>
14146 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
14147 * src/getargs.c (trace_types, trace_args): Adjust.
14148 * src/reader.c (grammar_current_rule_prec_set)
14149 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
14150 Standardize error messages.
14151 And s/@prec/%prec/!
14152 (reader): Use trace_flag to enable scanner/parser debugging,
14153 instead of an adhoc scheme.
14154 * src/scan-gram.l: Remove trailing debugging code.
14156 2002-10-16 Paul Eggert <eggert@twinsun.com>
14158 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
14161 * NEWS: Officially drop support for building Bison with K&R C,
14162 since it didn't work anyway and it's not worth worrying about.
14163 * Makefile.maint (wget_files): Remove ansi2knr.c.
14164 (ansi2knr.c-url_prefix): Remove.
14165 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
14166 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
14167 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
14169 2002-10-15 Paul Eggert <eggert@twinsun.com>
14171 Stop using the "enum_" trick for K&R-style function definitions;
14172 it confused me, and I was the author! Instead, assume that people
14173 who want to use K&R C compilers (when using these modules in GCC,
14174 perhaps?) will run ansi2knr.
14176 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
14177 All uses of "enum_" changed to "enum ".
14178 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
14179 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
14181 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

14189 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
14190 Use function prototypes; this removes the need for declaring
14191 static functions simply to provide their prototypes.
14192 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

14249 2002-10-14 Akim Demaille <akim@epita.fr>
14251 * tests/Makefile.am (maintainer-check-posix): New.
14253 2002-10-14 Akim Demaille <akim@epita.fr>
14255 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
14258 2002-10-14 Akim Demaille <akim@epita.fr>
14260 * src/tables.c (table_ninf_remap): base -> tab.
14261 Reported by Matt Rosing.
14263 2002-10-14 Paul Eggert <eggert@twinsun.com>
14265 * tests/action.at, tests/calc.at, tests/conflicts.at,
14266 tests/cxx-type.at, tests/headers.at, tests/input.at,
14267 tests/regression.at, tests/synclines.at, tests/torture.at:
14268 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
14269 so that the tests still work even if POSIXLY_CORRECT is set.
14270 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
14272 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
14273 for portability to K&R hosts. Fix typo: signed char is guaranteed
14274 only to 127, not to 128.
14275 * data/glr.c (yysigned_char): New type.
14276 * data/yacc.c (yysigned_char): Likewise.
14277 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
14279 2002-10-13 Paul Eggert <eggert@twinsun.com>
14281 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
14282 true due to limited range of data type" warning from GCC.
14284 * data/c.m4 (b4_token_defines): Protect against double-inclusion
14285 by wrapping enum yytokentype's definition inside #ifndef
14286 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
14288 2002-10-13 Akim Demaille <akim@epita.fr>
14290 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
14291 Un yy- yyrhs to avoid the name clash with the global YYRHS.
14293 2002-10-13 Akim Demaille <akim@epita.fr>
14295 * Makefile.maint: Update from Autoconf 2.54.
14296 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
14298 2002-10-13 Akim Demaille <akim@epita.fr>
14300 * src/print.c (print_state): Separate the list of solved conflicts
14301 from the other items.
14302 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
14304 2002-10-13 Akim Demaille <akim@epita.fr>
14306 Let nondeterministic skeletons be usable with deterministic
14309 With the patch, GAWK compiled by GCC without -O2 passes its test
14310 suite using a GLR parser driven by LALR tables. It fails with -O2
14311 because `struct stat' gives two different answers on my machine:
14312 88 (definition of an auto var) and later 96 (memset on this var).
14313 Hence the stack is badly corrumpted. The headers inclusion is to
14314 blame: if I move the awk.h inclusion before GLR's system header
14315 inclusion, the two struct stat have the same size.
14317 * src/tables.c (pack_table): Always create conflict_table.
14318 (token_actions): Always create conflict_list.
14319 * data/glr.c (YYFLAG): Remove, unused.
14321 2002-10-13 Akim Demaille <akim@epita.fr>
14323 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
14325 (VALGRIND, GXX): New.
14326 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
14327 * tests/bison.in: Run $PREBISON a pre-command.
14328 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)

14332 2002-10-13 Akim Demaille <akim@epita.fr>
14334 * data/glr.c: Formatting changes.
14335 Tweak some trace messages to match yacc.c's.
14337 2002-10-13 Akim Demaille <akim@epita.fr>
14339 GLR parsers sometimes raise parse errors instead of performing the
14341 Reported by Charles-Henry de Boysson.
14343 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
14344 check the length of the traces when %glr.
14345 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
14347 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
14349 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
14350 (yyltype): Remove the yy prefix from the member names.
14351 (yytable): Complete its comment.
14352 (yygetLRActions): Map error action number from YYTABLE from
14354 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
14355 (which was a bug: it should have been YYTABEL_NINF, and yet it was
14356 not satisfying as we could compare an YYACTION computed from
14357 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
14358 only value for error actions.
14359 (yyreportParseError): In verbose parse error messages, don't issue
14360 `error' in the list of expected tokens.
14361 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
14362 next action to perform to match glr.c's decoding.
14363 (yytable): Complete its comment.

14367 Fix problem reported by Henrik Grubbstroem in
14368 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
14369 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
14370 because the Bison parser reads the second action before reducing
14372 * src/scan-gram.l (rule_length): New static var.
14373 Use it to keep track of the rule length in the scanner, since
14374 we can't expect the parser to be in lock-step sync with the scanner.
14375 (handle_action_dollar, handle_action_at): Use this var.
14376 * tests/actions.at (Exotic Dollars): Test for the problem.
14378 2002-10-12 Paul Eggert <eggert@twinsun.com>
14380 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.

14382 Include <sys/time.h> when checking for clock_t and struct tms.
14383 Use same include order as source.
14384 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
14385 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
14387 * lib/timevar.c: Update copyright date and clarify comments.
14388 (get_time) [IN_GCC]: Keep the GCC version for reference.
14390 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
14391 GCC version as of today, then merge Bison's changes.
14392 Change "GCC" to "Bison" in copyright notice. timevar.def's
14393 author is Akim, so change that too.
14395 * src/reader.c (grammar_current_rule_check):
14396 Don't worry about the default action if $$ is untyped.
14397 Prevents bogus warnings reported by Jim Gifford in

14401 * data/glr.c, data/lalr1.cc, data/yacc.c:
14402 Output token definitions before the first part of user declarations.
14403 Fixes compatibility problem reported by Jim Gifford for kbd in

14408 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
14409 (yyparse): here. This undoes some of the 2002-07-25 change.
14410 Compatibility problem reported by Ralf S. Engelschall with
14411 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

14426 Portability fixes for bitsets; this also avoids several GCC
14429 * lib/abitset.c: Include <stddef.h>, for offsetof.
14430 * lib/lbitset.c: Likewise.
14432 * lib/abitset.c (abitset_bytes): Return a size that is aligned
14433 properly for vectors of objects. Do not assume that adding a
14434 header size to a multiple of a word size yields a value that is
14435 properly aligned for the whole union.
14436 * lib/bitsetv.c (bitsetv_alloc): Likewise.
14438 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
14439 unique names for structures.

14471 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
14472 All instances of parameters of type enum bitset_opts are now of

14474 for enum_bitset_type.
14475 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
14476 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
14478 Do not use "struct bitset_struct" to mean different things in
14479 different modules. Not only is this confusing, it violates
14480 the C Standard, which requires that structure types in different
14481 modules must be compatible if one is to be passed to the other.
14482 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
14483 All instances of "struct bitset_struct *" replaced with "bitset".
14484 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
14485 (union bitset_union, struct abitset_struct, struct ebitset_struct,

14494 bitset_struct): Remove.
14495 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
14498 Do not call a function of type T using a call that assumes the
14499 function is of a different type U. Standard C requires that a
14500 function must be called with a type that is compatible with its

14523 Use offsetof, for simplicity.
14525 2002-10-06 Paul Eggert <eggert@twinsun.com>
14527 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
14528 the same width as int. This reapplies a hunk of the 2002-08-12 patch
14529 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
14530 which was inadvertently undone by the 2002-09-30 patch.

14532 the same width as int.
14534 2002-10-04 Paul Eggert <eggert@twinsun.com>
14538 * configure.ac (AC_INIT), NEWS: Increment version number.
14540 * doc/bison.texinfo: Minor spelling, grammar, and white space
14542 (Symbols): Mention that any negative value returned from yylex
14543 signifies end-of-input. Warn about negative chars. Mention
14544 the portable Standard C character set.
14546 The GNU coding standard says CFLAGS and YFLAGS are reserved
14547 for the installer to set.
14548 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
14549 * src/Makefile.am (AM_CFLAGS): Likewise.
14550 (AM_YFLAGS): Renamed from YFLAGS.
14552 Fix some MAX and MIN problems.

14556 * src/reader.c (reader): Use it.
14558 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
14559 POSIX 1003.1-2001 has removed fgrep.
14561 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>

14754 * data/yacc.c: Guard the declaration of yytoknum also with
14755 `#ifdef YYPRINT', so it is declared only when used.

14792 as int, and similarly for yyposn and YYINDEX.

14834 PROTOTYPES to check for prototypes, and "defined __STDC__" to

14884 to void, to avoid a GCC warning when --disable-nls is in effect.

14889 as it mishandles negative chars and it may not work as expected
14890 outside the C locale.
14892 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
14893 this is a GCC extension and is not portable to other compilers.

14900 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
14903 * tests/regression.at: Do not use 'cc -c input.c -o input';
14904 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
14906 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
14907 exit status as failure, not just exit status 1. Sun C exits
14908 with status 2 sometimes.

14930 * tests/conflicts.at, tests/reduce.at: Adjust.

14957 2002-08-01 Akim Demaille <akim@epita.fr>

15075 different: save its reduction (accept) instead of having a state
15076 without any action (no shift or goto, no reduce).
15077 Note: the final state is now a ``regular'' state, i.e., the
15078 parsers now contain `reduce 0' as default reduction.
15079 Nevertheless, since they decide to `accept' when yystate =
15080 final_state, they still will not reduce rule 0.

15126 yycontrol without making too strong assumptions on the parser
15128 * src/output.c (prepare_tokens): Use the real 0th value of
15129 token_translations instead of `0'.
15130 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
15132 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
15133 for the time being: %locations ought to provide it to yyerror.
15135 2002-07-25 Akim Demaille <akim@epita.fr>
15137 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
15138 * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./.
15139 * tests/regression.at (Web2c Actions): Adjust.

15148 Iterate from 0 to nrules.
15149 Use rule_number_as_item_number and item_number_as_rule_number.
15150 Adjust to `derive' now containing possibly 0.
15151 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
15152 Handle the `- 1' part in rule numbers from/to item numbers.
15153 * src/conflicts.c (log_resolution): Fix the message which reversed
15155 * src/output.c (action_row): Initialize default_rule to -1.

16676 values of $$, $n and so forth, output invocation to b4_lhs_value,
16677 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
16678 Note: this patch partially drops `semantic-parser' support: it
16679 always does `rule_length - n', where semantic parsers ought to

16753 if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
16754 constructors or destructors.

16793 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
16794 etc. instead of 10, 20, 30 (which was used to `jump' over error
16795 (256) and undefined (2)).
16797 2002-04-22 Akim Demaille <akim@epita.fr>

16834 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
16835 full stderr, and strip it according to the bison options, instead
16836 of composing the error message from different bits.
16837 This makes it easier to check for several error messages.
16838 Adjust all the invocations.
16839 Add an invocation exercising the error token.
16840 Add an invocation demonstrating a stupid error message.
16841 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

16860 `user_token_number_max'.
16861 Output `undef_token_number'.

16882 * src/gram.h (item_number_t): New, the type of item numbers in
16883 RITEM. Note that it must be able to code symbol numbers as
16884 positive number, and the negation of rule numbers as negative

16887 * src/reduce.c (rule): Remove this `short *' pointer: use
16889 * src/system.h (MINSHORT, MAXSHORT): Remove.

17058 Be sure to distinguish the initial from the final state.

17061 * src/closure.c (closure): Now that the initial state has its
17062 items properly set, there is no need for a special case when
17063 creating `ruleset'.
17065 As a result, now the rule 0, reducing to $axiom, is visible in the

17099 (reduce_output, dump_grammar): Adjust.
17100 * src/print.c (print_grammar): It is no longer needed to check for
17101 the usefulness of a rule, as useless rules are beyond `nrules + 1'.

17104 2002-04-07 Akim Demaille <akim@epita.fr>
17106 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
17107 lacking `+ 1' to nrules, Bison reported as useless a token if it
17108 was used solely to set the precedence of the last rule...
17110 2002-04-07 Akim Demaille <akim@epita.fr>
17112 * data/bison.c++, data/bison.simple: Don't output the current file
17113 name in #line, to avoid useless diffs between two identical
17114 outputs under different names.
17116 2002-04-07 Akim Demaille <akim@epita.fr>
17118 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

17133 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
17134 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
17135 RHS, instead of being an index in RITEMS.

17504 (output_skeleton): Don't look for the skeleton location, let m4 do
17506 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
17508 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
17509 (prepare): Given that for the time being changesyntax is not
17510 usable in M4, rename the muscles using `-' to `_'.

17556 * tests/regression.at (%nonassoc and eof): Adjust to newest

17654 * src/files.c (base_name): Rename as full_base_name to avoid
17655 clashes with `base_name ()'.
17656 (filename_split): New.
17657 (compute_base_names): N-th rewrite, using filename_split.
17659 2002-01-08 Akim Demaille <akim@epita.fr>
17661 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
17662 New, stolen from the Fileutils 4.1.
17663 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
17664 * configure.in: Check for the presence of memrchr, and of its
17667 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
17669 * lib/hash.h (__P): Added definition for this macro.
17670 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
17671 BUILT_SOURCES, to ensure they are generated first.
17672 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
17673 %error-verbose to allow bootstrapping with bison 1.30x.
17675 2002-01-06 Akim Demaille <akim@epita.fr>
17677 * src/reader.c (parse_braces): Don't fetch the next char, the
17678 convention is to fetch on entry.
17679 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
17680 'switch' without a following semicolon.
17681 * tests/regression.at (braces parsing): New.
17683 2002-01-06 Akim Demaille <akim@epita.fr>
17685 Bison is dead wrong in its RR conflict reports.
17687 * tests/torture.at (GNU Cim Grammar): New.
17688 * src/conflicts.c (count_rr_conflicts): Fix.
17690 2002-01-06 Akim Demaille <akim@epita.fr>
17692 Creating package.m4 from configure.ac causes too many problems.
17694 * tests/Makefile.am (package.m4): Create it by hand,
17695 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
17697 2002-01-06 Akim Demaille <akim@epita.fr>
17699 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
17702 2002-01-04 Paul Eggert <eggert@twinsun.com>
17704 * doc/bison.texinfo (Debugging):
17705 Remove YYSTDERR; it's no longer defined or used.
17706 Also, s/cstdio.h/cstdio/.
17708 2002-01-03 Akim Demaille <akim@epita.fr>
17710 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
17712 2002-01-03 Akim Demaille <akim@epita.fr>
17714 * src/parse-skel.y (process_skeleton): Don't bind the parser's
17715 tracing code to --trace, wait for a better --trace option, with
17718 2002-01-03 Akim Demaille <akim@epita.fr>
17720 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
17721 The ISO C++ standard is extremely clear about it: stderr is
17722 considered a macro, not a regular symbol (see table 94 `Header
17723 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
17724 Therefore std:: does not apply to it. It still does with fprintf.
17725 Also, s/cstdio.h/cstdio/.
17727 2002-01-03 Akim Demaille <akim@epita.fr>
17729 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
17730 for non system headers.
17732 2002-01-02 Akim Demaille <akim@epita.fr>
17734 Equip the skeleton chain with location tracking, runtime trace,
17735 pure parser and scanner.
17737 * src/parse-skel.y: Request a pure parser, locations, and prefix
17739 (%union): Having several members with the same type does not help
17740 type mismatches, simplify.
17741 (YYPRINT, yyprint): New.
17742 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
17743 (skel_error): this.
17745 * src/scan-skel.l: Adjust to these changes.
17746 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
17747 (LOCATION_PRINT, skel_control_t): New.
17749 2001-12-30 Akim Demaille <akim@epita.fr>
17751 * src/parse-skel.y: Get rid of the shift/reduce conflict:
17752 replace `gb' with BLANKS.
17753 * src/scan-skel.l: Adjust.
17755 2001-12-30 Akim Demaille <akim@epita.fr>
17757 * src/system.h: We don't need nor want bcopy.
17758 Throw away MS-DOS crap: we don't need getpid.
17759 * configure.in: We don't need strndup. It was even causing
17760 problems: because Flex includes the headers *before* us,
17761 _GNU_SOURCE is not defined by config.h, and therefore strndup was
17763 * lib/xstrndup.c: New.
17764 * src/scan-skel.l: Use it.
17765 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
17766 * src/parse-skel.y: Use %directives instead of #defines.
17768 2001-12-30 Akim Demaille <akim@epita.fr>
17770 * src/skeleton.h: New.
17771 * src/output.c (output_parser, output_master_parser): Remove, dead
17773 * src/output.h (get_lines_number, actions_output, guards_output)
17774 (token_definitions_output): Prototype them.
17775 * src/parse-skel.y: Add the license notice.
17776 Include output.h and skeleton.h.
17777 (process_skeleton): Returns void, and takes a single parameter.
17778 * src/scan-skel.l: Add the license notice.
17779 Include skeleton.h.
17780 Don't use %option yylineno: it seems that then Flex imagines
17781 REJECT has been used, and therefore it won't reallocate its
17782 buffers (which makes no other sense to me than a bug). It results
17783 in warnings for `unused: yy_flex_realloc'.
17785 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
17787 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17788 (MUSCLE_INSERT_PREFIX): ...to there.
17789 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17790 (MUSCLE_INSERT_PREFIX): Move from here...
17792 * src/bison.hairy: Add a section directive. Put braces around muscle
17793 names. This parser skeleton is still broken, but Bison should not
17794 choke on a bad muscle 'syntax'.
17795 * src/bison.simple: Add a section directive. Put braces around muscle
17798 * src/files.h (strsuffix, stringappend): Add declarations.
17799 (tab_extension): Add declaration.
17800 (short_base_name): Add declaration.
17802 * src/files.c (strsuffix, stringappend): No longer static. These
17803 functions are used in the skeleton parser.
17804 (tab_extension): New.
17805 (compute_base_names): Use the computations done in this function
17806 to guess if the generated parsers should have '.tab' in their
17808 (short_base_name): No longer static.
17810 * src/output.c (output_skeleton): New.
17811 (output): Disable call to output_master_parser, and give a try to
17812 a new skeleton handling system.
17813 (guards_output, actions_output): No longer static.
17814 (token_definitions_output, get_lines_number): No longer static.
17816 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
17818 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
17821 * src/parse-skel.y: New file.
17822 * src/scan-skel.l: New file.
17824 2001-12-29 Akim Demaille <akim@epita.fr>
17826 %name-prefix is broken.
17828 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
17829 Adjust all dependencies.
17830 * tests/headers.at (export YYLTYPE): Strengthen this test: use
17833 Renaming yylval but not yylloc is not consistent. Now we do.
17835 * src/bison.simple: Prefix yylloc if used.
17836 * doc/bison.texinfo (Decl Summary): Document that.
17838 2001-12-29 Akim Demaille <akim@epita.fr>
17840 * doc/bison.texinfo: Promote `%long-directive' over
17842 Remove all references to fixed-output-files, yacc is enough.
17844 2001-12-29 Akim Demaille <akim@epita.fr>
17846 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
17847 user prologue. These are defaults.
17848 * tests/actions.at (Mid-rule actions): Make sure the user can
17849 define YYDEBUG and YYERROR_VERBOSE.
17851 2001-12-29 Akim Demaille <akim@epita.fr>
17853 * src/output.c (header_output): Don't forget to export YYLTYPE and
17855 * tests/headers.at (export YYLTYPE): New, make sure it does.
17856 * tests/regression.at (%union and --defines, Invalid CPP headers):
17858 * tests/headers.at: here.
17860 2001-12-29 Akim Demaille <akim@epita.fr>
17862 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
17864 2001-12-29 Akim Demaille <akim@epita.fr>
17866 * tests/actions.at (Mid-rule actions): Output on a single line
17867 instead of several.
17869 2001-12-29 Akim Demaille <akim@epita.fr>
17871 * doc/bison.texinfo: Formatting changes.
17873 2001-12-29 Akim Demaille <akim@epita.fr>
17875 Don't store the token defs in a muscle, just be ready to output it
17876 on command. Now possible via `symbols'. Fixes a memory leak.
17878 * src/output.c (token_definitions_output): New.
17879 (output_parser, header_output): Use it.
17880 * src/reader.c (symbols_save): Remove.
17882 2001-12-29 Akim Demaille <akim@epita.fr>
17884 * src/bison.simple: Do not provide a default for YYSTYPE and
17885 YYLTYPE before the user's prologue. Otherwise it's hardly... a
17888 2001-12-29 Akim Demaille <akim@epita.fr>
17890 Mid-rule actions are simply... ignored!
17892 * src/reader.c (readgram): Be sure to attach mid-rule actions to
17893 the empty-rule associated to the dummy symbol, not to the host
17895 * tests/actions.at (Mid-rule actions): New.
17897 2001-12-29 Akim Demaille <akim@epita.fr>
17901 * src/reader.c (reader): Free grammar.
17903 2001-12-29 Akim Demaille <akim@epita.fr>
17907 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
17908 since it allocates it for each state, although only one is needed.
17909 (allocate_storage): Do it here.
17911 2001-12-29 Akim Demaille <akim@epita.fr>
17913 * src/options.h, src/options.c (create_long_option_table): Rename
17915 (long_option_table_new): this, with a clearer prototype.
17916 (percent_table): Remove, unused,
17917 * src/getargs.c (getargs): Adjust.
17919 2001-12-29 Akim Demaille <akim@epita.fr>
17921 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
17922 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
17925 2001-12-29 Akim Demaille <akim@epita.fr>
17927 * src/lalr.c (build_relations): Rename `states' as `states1'.
17928 Sorry, I don't understand exactly what it is, no better name...
17930 2001-12-29 Akim Demaille <akim@epita.fr>
17932 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
17933 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
17934 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
17937 2001-12-29 Akim Demaille <akim@epita.fr>
17939 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
17942 2001-12-29 Akim Demaille <akim@epita.fr>
17944 * src/reader.c, src/reader.h (user_toknums): Remove.
17945 Adjust all users to use symbols[i]->user_token_number.
17947 2001-12-29 Akim Demaille <akim@epita.fr>
17949 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
17950 Adjust all users to use symbols[i]->prec or ->assoc.
17952 2001-12-29 Akim Demaille <akim@epita.fr>
17954 * src/reader.c, src/reader.h (tags): Remove.
17955 Adjust all users to use symbols[i]->tag.
17957 2001-12-29 Akim Demaille <akim@epita.fr>
17959 * src/gram.h, src/gram.c (symbols): New, similar to state_table
17961 * src/reader.c (packsymbols): Fill this table.
17963 * src/conflicts.c (resolve_sr_conflict): Adjust.
17964 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
17966 Use symbols[i]->tag instead of tags[i].
17968 2001-12-29 Akim Demaille <akim@epita.fr>
17970 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
17971 In addition, put a comment in there, to replace...
17972 * tests/regression.at (%union and C comments): Remove.
17974 2001-12-29 Akim Demaille <akim@epita.fr>
17976 * tests/regression.at (Web2c Actions): Blindly move the actual
17977 output as expected output. The contents *seem* right to me, but I
17978 can't pretend reading perfectly parser tables... Nonetheless, all
17979 the other tests pass correctly, the table look OK, even though the
17980 presence of `$axiom' is to be noted: AFAICS it is useless (but
17983 2001-12-29 Akim Demaille <akim@epita.fr>
17985 * src/reader.c (readgram): Don't add the rule 0 if there were no
17986 rules read. In other words, add it _after_ having performed
17987 grammar sanity checks.
17988 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
17990 2001-12-29 Akim Demaille <akim@epita.fr>
17992 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
17993 visible, and some states have now a different number.
17995 2001-12-29 Akim Demaille <akim@epita.fr>
17997 * src/reader.c (readgram): Bind the initial rule's lineno to that
17999 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
18000 (Solved SR Conflicts): Adjust rule 0's line number.
18002 2001-12-29 Akim Demaille <akim@epita.fr>
18004 Fix the `GAWK Grammar' failure.
18006 * src/LR0.c (final_state): Initialize to -1 so that we do compute
18007 the reductions of the first state which was mistakenly confused
18008 with the final state because precisely final_state was initialized
18010 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
18011 now noticed by Bison.
18012 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
18013 have a reduction on $default.
18015 2001-12-29 Akim Demaille <akim@epita.fr>
18017 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
18019 * src/closure.c (print_closure): Likewise.
18020 * src/derives.c (print_derives): Likewise.
18021 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
18024 2001-12-29 Akim Demaille <akim@epita.fr>
18026 * src/lalr.c (lookaheads_print): New.
18027 (lalr): Call it when --trace-flag.
18028 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
18031 2001-12-29 Akim Demaille <akim@epita.fr>
18033 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
18034 when walking through ritem, even via rule->rhs.
18035 * src/reduce.c (dump_grammar, useful_production, reduce_output)
18036 (useful_production, useless_nonterminals): Likewise.
18037 (reduce_grammar_tables): Likewise, plus update nritems.
18038 * src/nullable.c (set_nullable): Likewise.
18039 * src/lalr.c (build_relations): Likewise.
18040 * tests/sets.at (Nullable): Adjust.
18041 Fortunately, now, the $axiom is no longer nullable.
18043 2001-12-29 Akim Demaille <akim@epita.fr>
18045 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
18047 * src/gram.c (ritem_longest_rhs): Likewise.
18048 * src/reduce.c (nonterminals_reduce): Likewise.
18049 * src/print_graph.c (print_graph): Likewise.
18050 * src/output.c (output_rule_data): Likewise.
18051 * src/nullable.c (set_nullable): Likewise.
18053 2001-12-29 Akim Demaille <akim@epita.fr>
18055 * src/output.c: Comment changes.
18057 2001-12-27 Paul Eggert <eggert@twinsun.com>
18059 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
18060 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
18061 Sparc, as they were causing more porting problems than the
18062 (minor) performance improvement was worth.
18064 Also, catch up with 1.31's YYSTD.
18066 2001-12-27 Akim Demaille <akim@epita.fr>
18068 * src/output.c (output_gram): Rely on nritems, not the
18069 0-sentinel. See below.
18070 Use -1 as separator, not 0.
18071 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
18072 Rely on -1 as separator in yyrhs, instead of 0.
18073 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
18074 twice `Now at end of input', therefore there are two lines less to
18077 2001-12-27 Akim Demaille <akim@epita.fr>
18079 * tests/regression.at (Unresolved SR Conflicts):
18080 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
18083 2001-12-27 Akim Demaille <akim@epita.fr>
18085 * src/LR0.c (new_state): Recognize the final state by the fact it
18086 is reached by eoftoken.
18087 (insert_start_shifting_state, insert_eof_shifting_state)
18088 (insert_accepting_state, augment_automaton): Remove, since now
18089 these states are automatically computed from the initial state.
18090 (generate_states): Adjust.
18091 * src/print.c: When reporting a rule number to the user, substract
18092 1, so that the axiom rule is rule 0, and the first user rule is 1.
18093 * src/reduce.c: Likewise.
18094 * src/print_graph.c (print_core): For the time being, just as for
18095 the report, depend upon --trace-flags to dump the full set of
18097 * src/reader.c (readgram): Once the grammar read, insert the rule
18098 0: `$axiom: START-SYMBOL $'.
18099 * tests/set.at: Adjust: rule 0 is now displayed, and since the
18100 number of the states has changed (the final state is no longer
18101 necessarily the last), catch up.
18103 2001-12-27 Akim Demaille <akim@epita.fr>
18105 Try to make the use of the eoftoken valid. Given that its value
18106 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
18107 is used instead of > 0 where appropriate, (ii), depend upon nritems
18108 instead of the 0-sentinel.
18110 * src/gram.h, src/gram.c (nritems): New.
18111 Expected to be duplication of nitems, but for the time being...
18112 * src/reader.c (packgram): Assert nritems and nitems are equal.
18113 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
18114 * src/closure.c (print_closure, print_fderives): Likewise.
18115 * src/gram.c (ritem_print): Likewise.
18116 * src/print.c (print_core, print_grammar): Likewise.
18117 * src/print_graph.c: Likewise.
18119 2001-12-27 Akim Demaille <akim@epita.fr>
18121 * src/main.c (main): If there are complains after grammar
18122 reductions, then output the report anyway if requested, then die.
18123 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
18124 * src/reader.c (eoftoken): New.
18125 (parse_token_decl): If the token being defined has value `0', it
18127 (packsymbols): No longer hack `tags' to insert `$' by hand.
18128 Be sure to preserve the value of the eoftoken.
18129 (reader): Make sure eoftoken is defined.
18130 Initialize nsyms to 0: now eoftoken is created just like the others.
18131 * src/print.c (print_grammar): Don't special case the eof token.
18132 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
18133 lie anyway, albeit pleasant.
18134 * tests/calc.at: Exercise error messages with eoftoken.
18135 Change the grammar so that empty input is invalid.
18136 Adjust expectations.
18137 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
18139 2001-12-27 Akim Demaille <akim@epita.fr>
18141 * configure.in: Check the protos of strchr ans strspn.
18142 Replace strchr if needed.
18143 * src/system.h: Provide the protos of strchr, strspn and memchr if
18145 * lib/strchr.c: New.
18146 * src/reader.c (symbols_save): Use strchr.
18148 2001-12-27 Akim Demaille <akim@epita.fr>
18150 * src/print.c, src/print_graph.c (escape): New.
18151 Use it to quote the TAGS outputs.
18152 * src/print_graph.c (print_state): Now errors are in red, and
18153 reductions in green.
18154 Prefer high to wide: output the state number on a line of its own.
18156 2001-12-27 Akim Demaille <akim@epita.fr>
18158 * src/state.h, src/state.c (reductions_new): New.
18159 * src/LR0.c (set_state_table): Let all the states have a
18160 `reductions', even if reduced to 0.

18179 2001-12-27 Akim Demaille <akim@epita.fr>
18181 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
18182 * src/print.c: here.
18183 (lookaheadset, shiftset): New, used as additional storage by
18185 (print_results): Adjust.
18186 (print_shifts, print_gotos, print_errs): New, extracted from...
18187 (print_actions): here.
18188 * src/print_graph.c (print_actions): Remove dead code.
18190 2001-12-27 Akim Demaille <akim@epita.fr>
18192 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
18195 2001-12-27 Akim Demaille <akim@epita.fr>
18197 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
18198 (build_relations): Adjust.
18200 2001-12-27 Akim Demaille <akim@epita.fr>
18202 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
18205 2001-12-27 Akim Demaille <akim@epita.fr>
18207 * src/reader.c (packgram): Catch nitems overflows.
18209 2001-12-27 Akim Demaille <akim@epita.fr>
18211 * src/files.c, src/files.h (guard_obstack): Remove.
18212 * src/output.c (output): Adjust.
18213 * src/reader.c (parse_braces): New, factoring...
18214 (copy_action, copy_guard): these two which are renamed as...
18215 (parse_action, parse_guard): these.
18216 As a voluntary consequence, using braces around guards is now
18219 2001-12-27 Akim Demaille <akim@epita.fr>
18221 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
18222 * src/reader.c (symbol_list): `guard' and `guard_line' are new
18224 (symbol_list_new): Adjust.
18225 (copy_action): action_line is the first line, not the last.
18226 (copy_guard): Just as for actions, store the `action' only, not
18227 the switch/case/break flesh.
18228 Don't parse the user action that might follow the guard, let...
18229 (readgram): do it, i.e., now, there can be an action after a
18231 In other words the guard is just explicitly optional.
18232 (packgram): Adjust.
18233 * src/output.c (guards_output): New.
18234 (output_parser): Call it when needed.
18235 (output): Also free the guard and attrs obstacks.
18236 * src/files.c, src/files.h (obstack_save): Remove.
18237 (output_files): Remove.
18238 As a result, if one needs the former `.act' file, using an
18239 appropriate skeleton which requires actions and guards is now
18241 * src/main.c (main): Adjust.
18242 * tests/semantic.at: New.
18243 * tests/regression.at: Use `input.y' as input file name.
18244 Avoid 8+3 problems by requiring input.c when the test needs the
18247 2001-12-27 Akim Demaille <akim@epita.fr>
18249 * src/reader.c (symbol_list_new): Be sure to initialize all the
18252 2001-12-27 Akim Demaille <akim@epita.fr>
18254 All the hacks using a final pseudo state are now useless.
18256 * src/LR0.c (set_state_table): state_table holds exactly nstates.
18257 * src/lalr.c (nLA): New.
18258 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
18259 instead of lookaheadsp from the pseudo state (nstate + 1).
18261 2001-12-27 Akim Demaille <akim@epita.fr>
18263 * src/output.c (action_row, token_actions): Use a state_t instead
18264 of a integer, and nlookaheads instead of the following state's

18269 * src/conflicts.c (log_resolution, flush_shift)
18270 (resolve_sr_conflict, set_conflicts, solve_conflicts)
18271 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
18272 (conflicts_print, print_reductions): Use a state_t instead of an
18273 integer when referring to a state.
18274 As much as possible, depend upon nlookaheads, instead of the
18275 `lookaheadsp' member of the following state (since lookaheads of
18276 successive states are successive, the difference between state n + 1
18277 and n served as the number of lookaheads for state n).
18278 * src/lalr.c (add_lookback_edge): Likewise.
18279 * src/print.c (print_core, print_actions, print_state)
18280 (print_results): Likewise.
18281 * src/print_graph.c (print_core, print_actions, print_state)
18282 (print_graph): Likewise.
18283 * src/conflicts.h: Adjust.
18285 2001-12-27 Akim Demaille <akim@epita.fr>
18287 * src/bison.hairy: Formatting/comment changes.
18289 Remove `register' indications.
18290 Add plenty of `static'.
18292 2001-12-27 Akim Demaille <akim@epita.fr>
18294 * src/output.c (prepare): Drop the muscle `ntbase' which
18295 duplicates ntokens.
18296 * src/bison.simple: Formatting/comment changes.
18297 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
18298 is an undocumented synonym.
18300 2001-12-22 Akim Demaille <akim@epita.fr>
18302 * src/output.c (output_table_data): Change the prototype to use
18303 `int' for array ranges: some invocations do pass an int, not a
18305 Reported by Wayne Green.
18307 2001-12-22 Akim Demaille <akim@epita.fr>
18309 Some actions of web2c.y are improperly triggered.
18310 Reported by Mike Castle.
18312 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
18313 * tests/regression.at (Web2c): Rename as...
18314 (Web2c Report): this.
18315 (Web2c Actions): New.
18317 2001-12-22 Akim Demaille <akim@epita.fr>
18319 Reductions in web2c.y are improperly reported.
18320 Reported by Mike Castle.
18322 * src/conflicts.c (print_reductions): Fix.
18323 * tests/regression.at (Web2c): New.
18325 2001-12-18 Akim Demaille <akim@epita.fr>
18327 Some host fail on `assert (!"foo")', which expands to
18328 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
18329 Reported by Nelson Beebee.
18331 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
18332 `#define it_succeeded 0' and `assert (it_succeeded)'.
18334 2001-12-17 Marc Autret <autret_m@epita.fr>
18336 * src/bison.simple: Don't hard code the skeleton line and filename.
18337 * src/output.c (output_parser): Rename 'line' as 'output_line'.
18338 New line counter 'skeleton_line' (skeleton-line muscle).
18340 2001-12-17 Paul Eggert <eggert@twinsun.com>
18342 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
18343 YYDEBUG must be defined to a nonzero value.
18345 * src/bison.simple (yytname): Do not assume that the user defines
18346 YYDEBUG to a properly parenthesized expression.
18348 2001-12-17 Akim Demaille <akim@epita.fr>
18350 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
18351 nlookaheads is a new member.
18353 * src/lalr.h (nlookaheads): Remove this orphan declaration.
18354 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
18357 2001-12-17 Akim Demaille <akim@epita.fr>
18359 * src/files.h, src/files.c (open_files, close_files): Remove.
18360 * src/main.c (main): Don't open/close files, nor invoke lex_free,
18362 * src/reader.c (reader): Do it.
18364 2001-12-17 Akim Demaille <akim@epita.fr>
18366 * src/conflicts.c (print_reductions): Formatting changes.
18368 2001-12-17 Akim Demaille <akim@epita.fr>
18370 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
18371 (flush_reduce): New.
18372 (resolve_sr_conflict): Adjust.
18374 2001-12-17 Akim Demaille <akim@epita.fr>
18376 * src/output.c (output_obstack): Be static and rename as...
18377 (format_obstack): this, to avoid any confusion with files.c's
18379 * src/reader.h (muscle_obstack): Move to...
18380 * src/output.h: here, since it's defined in output.c.
18382 2001-12-17 Akim Demaille <akim@epita.fr>
18384 * src/output.c (action_row, save_column, default_goto)
18385 (sort_actions, matching_state, pack_vector): Better variable
18388 2001-12-17 Akim Demaille <akim@epita.fr>
18390 * src/output.c: Various formatting changes.
18392 2001-12-17 Akim Demaille <akim@epita.fr>
18394 * src/files.c (output_files): Free the output_obstack.
18395 * src/main.c (main): Call print and print_graph conditionally.
18396 * src/print.c (print): Work unconditionally.
18397 * src/print_graph.c (print_graph): Work unconditionally.
18398 * src/conflicts.c (log_resolution): Output only if verbose_flag.
18400 2001-12-16 Marc Autret <autret_m@epita.fr>
18402 * src/output.c (actions_output): Fix. When we use %no-lines,
18403 there is one less line per action.
18405 2001-12-16 Marc Autret <autret_m@epita.fr>
18407 * src/bison.simple: Remove a useless #line directive.
18408 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
18409 * src/output.c (get_lines_number): New.
18410 (output_parser): Adjust, now takes care about the lines of a
18412 Fix line numbering.
18413 (actions_output): Computes the number of lines taken by actions.
18414 (output_master_parser): Insert new skeleton which is the name of
18415 the output parser file name.
18417 2001-12-15 Marc Autret <autret_m@epita.fr>
18419 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
18421 2001-12-15 Marc Autret <autret_m@epita.fr>
18423 * src/output.c (output_gram): Keep track of the hairy one.
18425 2001-12-15 Akim Demaille <akim@epita.fr>
18427 Make `make distcheck' work.
18429 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
18430 system.h which uses libgettext.h.
18432 2001-12-15 Akim Demaille <akim@epita.fr>
18434 * src/nullable.c (set_nullable): Useless rules must be skipped,
18435 otherwise, since we range over their symbols, we might look at a
18436 nonterminal which no longer ``exists'', i.e., it is not counted in
18437 `nvars', hence we overflow our arrays.
18439 2001-12-15 Akim Demaille <akim@epita.fr>
18441 The header can also be produced directly, without any obstack!
18444 * src/files.c, src/files.h (defines_obstack): Remove.
18445 (compute_header_macro): Global.
18446 (defines_obstack_save): Remove.
18447 * src/reader.c (parse_union_decl): No longer output to
18448 defines_obstack: its content can be found in the `stype' muscle
18450 (output_token_translations): Merge into...
18451 (symbols_output): this.
18453 (symbols_save): this.
18455 * src/output.c (header_output): New.
18458 2001-12-15 Akim Demaille <akim@epita.fr>
18460 * src/reader.c (parse_union_decl): Instead of handling two obstack
18461 simultaneously, use one to define the `stype' muscle, and use the
18462 value of the latter to fill defines_obstack.
18463 (copy_comment): Remove.
18464 (copy_comment2): Work for a single obstack.
18466 (copy_comment): this.
18468 2001-12-15 Akim Demaille <akim@epita.fr>
18470 * src/lex.c, src/lex.h (xgetc): No longer static.
18471 * src/reader.c (parse_union_decl): Revamp.
18473 2001-12-15 Akim Demaille <akim@epita.fr>
18475 Still making progress in separating Bison into (i) input, (ii)
18476 process, (iii) output: now we can directly output the parser file
18477 without using table_obstack at all.
18479 * src/files.c, src/files.h (table_obstack): Bye bye.
18480 (parser_file_name): New.
18481 * src/files.c (compute_output_file_names): Compute it.
18482 * src/output.c (actions_output, output_parser)
18483 (output_master_parser): To a file instead of an obstack.
18485 2001-12-15 Akim Demaille <akim@epita.fr>
18487 Attach actions to rules, instead of pre-outputting them to
18490 * src/gram.h (rule_t): action and action_line are new members.
18491 * src/reader.c (symbol_list): Likewise.
18492 (copy_action): Save the actions within the rule.
18493 (packgram): Save them in rule_table.
18494 * src/output.c (actions_output): New.
18495 (output_parser): Use it on `%%actions'.
18496 (output_rule_data): Don't free rule_table.
18498 (prepare): Don't save the `action' muscle.
18499 * src/bison.simple: s/%%action/%%actions/.
18501 2001-12-15 Akim Demaille <akim@epita.fr>
18503 * src/reader.c (copy_action): When --yacc, don't append a `;'
18504 to the user action: let it fail if lacking.
18505 Suggested by Arnold Robbins and Tom Tromey.
18507 2001-12-14 Akim Demaille <akim@epita.fr>
18509 * src/lex.c (literalchar): Simply return the char you decoded, non
18510 longer mess around with obstacks and int pointers.
18511 Adjust all callers.
18513 2001-12-14 Akim Demaille <akim@epita.fr>
18515 * src/lex.c (literalchar): Don't escape the special characters,
18516 just decode them, and keep them as char (before, eol was output as
18517 the 2 char string `\n' etc.).
18518 * src/output.c (output_rule_data): Use quotearg to output the
18521 2001-12-13 Paul Eggert <eggert@twinsun.com>
18523 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
18524 Do not infringe on the global user namespace when using C++.
18525 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
18526 All uses of `fprintf' and `stderr' changed.
18528 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
18530 2001-12-13 Akim Demaille <akim@epita.fr>
18532 The computation of nullable is broken: it doesn't handle empty
18535 * tests/torture.at (GNU AWK Grammar): New.
18536 * tests/sets.at (Nullable): New.
18537 * src/nullable.c (set_nullable): Instead of blindly looping over
18538 `ritems', loop over the rules, and then over their rhs's.
18540 Work around Autotest bugs.
18542 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
18543 frame, because Autotest understand lines starting with a `+' as
18544 traces from the shell. Then, they are not processed properly.
18545 Admittedly an Autotest bug, but we don't have time to wait for
18546 Autotest to catch up.
18547 * tests/regression.at (Broken Closure): Adjust to the new table
18550 * tests/sets.at: here.
18552 2001-12-13 Akim Demaille <akim@epita.fr>
18554 * src/closure.c (closure): Use nrules instead of playing tricks
18555 with BITS_PER_WORD.
18557 2001-12-13 Akim Demaille <akim@epita.fr>
18559 * src/print.c (print_actions): Output the handling of `$' as the
18560 traces do: shifting the token EOF. Before EOF was treated as a
18562 * tests/regression.at: Adjust some tests.
18563 * src/print_graph.c (print_core): Complete the set of items via
18564 closure. The next-to-final and final states are still unsatisfying,
18565 but that's to be addressed elsewhere.
18566 No longer output the rule numbers, but do output the state number.
18567 A single loop for the shifts + gotos is enough, but picked a
18568 distinct color for each.
18569 (print_graph): Initialize and finalize closure.
18571 2001-12-13 Akim Demaille <akim@epita.fr>
18573 * src/reader.c (readgram): Remove dead code, an strip useless
18575 (get_type): Remove, unused.
18577 2001-12-12 Akim Demaille <akim@epita.fr>
18579 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
18580 on that of lib/error.c.
18582 2001-12-12 Akim Demaille <akim@epita.fr>
18584 Some hosts don't like `/' in includes.
18586 * src/system.h: Include libgettext.h without qualifying the path.
18587 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
18590 2001-12-11 Marc Autret <autret_m@epita.fr>
18592 * src/output.c (output_parser): Remove useless muscle.
18594 2001-12-11 Marc Autret <autret_m@epita.fr>
18596 * src/bison.simple: Remove #line just before %%epilogue. It
18597 is now handled in ...
18598 * src/reader.c (read_additionnal_code): Add the output of a
18599 #line for the epilogue.
18601 2001-12-10 Marc Autret <autret_m@epita.fr>
18603 * src/reader.c (copy_definition): Re-use CPP-outed code which
18604 replace precedent remove.
18605 * src/bison.simple: Remove #line before %%prologue because
18606 %%input-line is wrong at this time.
18608 2001-12-10 Marc Autret <autret_m@epita.fr>
18610 * src/reader.c (symbols_output): Clean up.
18611 * src/output.c (output_gram, output): Clean up.
18613 2001-12-10 Akim Demaille <akim@epita.fr>
18615 * src/lalr.c (initialize_lookaheads): New. Extracted from...
18616 * src/LR0.c (set_state_table): here.
18617 * src/lalr.c (lalr): Call it.
18619 2001-12-10 Akim Demaille <akim@epita.fr>
18621 * src/state.h (shifts): Remove the `number' member: shifts are
18622 attached to state, hence no longer need to be labelled with a
18625 2001-12-10 Akim Demaille <akim@epita.fr>
18627 Now that states have a complete set of members, the linked list of
18628 shifts is useless: just fill directly the state's shifts member.
18630 * src/state.h (shifts): Remove the `next' member.
18631 * src/LR0.c (first_state, last_state): Remove.
18632 Adjust the callers.
18633 (augment_automaton): Don't look for the shifts that must be added
18634 a shift on EOF: it is those of the state we looked for! But now,
18635 since shifts are attached, it is no longer needed to looking
18636 merely by its id: its number.
18638 2001-12-10 Akim Demaille <akim@epita.fr>
18640 * src/LR0.c (augment_automaton): Better variable locality.
18641 Remove an impossible branch: if there is a state corresponding to
18642 the start symbol being shifted, then there is shift for the start
18643 symbol from the initial state.
18645 2001-12-10 Akim Demaille <akim@epita.fr>
18647 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
18648 only when appropriate: when insert_start_shifting_state' is not
18650 * tests/regression.at (Rule Line Numbers): Adjust.
18652 2001-12-10 Akim Demaille <akim@epita.fr>
18654 * src/LR0.c (augment_automaton): Now that all states have shifts,
18655 merge the two cases addition shifts to the initial state.
18657 2001-12-10 Akim Demaille <akim@epita.fr>
18659 * src/lalr.c (set_state_table): Move to...
18661 * src/lalr.c (lalr): Don't call it...
18662 * src/LR0.c (generate_states): do it.
18663 * src/LR0.h (first_state): Remove, only the table is used.
18665 2001-12-10 Akim Demaille <akim@epita.fr>
18667 * src/LR0.h (first_shift, first_reduction): Remove.
18668 * src/lalr.c: Don't use first_shift: find shifts through the
18671 2001-12-10 Akim Demaille <akim@epita.fr>
18673 * src/LR0.c: Attach shifts to states as soon as they are
18675 * src/lalr.c (set_state_table): Instead of assigning shifts to
18676 state, just assert that the mapping was properly done.
18678 2001-12-10 Akim Demaille <akim@epita.fr>
18680 * src/LR0.c (insert_start_shift): Rename as...
18681 (insert_start_shifting_state): this.
18682 (insert_eof_shifting_state, insert_accepting_state): New.
18683 (augment_automaton): Adjust.
18684 Better locality of the variables.
18685 When looking if the start_symbol is shifted from the initial
18686 state, using `while (... symbol != start_symbol ...)' sounds
18687 better than `while (... symbol < start_symbol ...)': If fail
18688 to see how the order between symbols could be relevant!
18690 2001-12-10 Akim Demaille <akim@epita.fr>
18692 * src/getargs.h: Don't declare `spec_name_prefix' and
18693 `spec_file_prefix', declared by src/files.h.
18694 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
18695 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
18696 * src/output.c (prepare): Adjust.
18697 * src/reader.c (symbols_output): Likewise.
18698 * src/vmsgetargs.c: Vaguely adjust, but who cares?
18700 2001-12-10 Akim Demaille <akim@epita.fr>
18702 * src/muscle_tab.c (muscle_init): NULL is a better default than
18705 2001-12-10 Akim Demaille <akim@epita.fr>
18707 * src/reader.c (reader): Calling symbols_output once is enough.
18709 2001-12-10 Akim Demaille <akim@epita.fr>
18711 Now that states have a complete set of members, the linked list of
18712 reductions is useless: just fill directly the state's reductions
18715 * src/state.h (struct reductions): Remove member `number' and
18717 * src/LR0.c (first_reduction, last_reduction): Remove.
18718 (save_reductions): Don't link the new reductions, store them in
18720 * src/lalr.c (set_state_table): No need to attach reductions to
18721 states, it's already done.
18722 * src/output.c (output_actions): No longer free the shifts, then
18723 the reductions, then the states: free all the states and their
18726 2001-12-10 Akim Demaille <akim@epita.fr>
18728 * src/options.c (OPTN, DRTV, BOTH): New.
18729 (option_table): Use them.
18731 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
18732 the job of system.h.
18733 * src/options.c: Don't include stdio.h and xalloc.h for the same
18736 2001-12-10 Akim Demaille <akim@epita.fr>
18738 * src/output.c (output, prepare): Make sure the values of the
18739 muscles `action' and `prologue' are 0-terminated.
18741 2001-12-10 Akim Demaille <akim@epita.fr>
18743 Clean up GCC warnings.
18745 * src/reader.c (copy_action): `buf' is not used.
18746 (parse_skel_decl): Be static.
18747 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
18748 * src/options.h (create_long_option_table): Have a real prototype.
18749 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
18750 (hash_delete_at): Return const void *.
18751 Adjust casts to preserve the const.
18753 2001-12-10 Akim Demaille <akim@epita.fr>
18755 * configure.in: Require 2.52g.
18756 M4 is not needed, but AUTOM4TE is.
18757 * m4/m4.m4: Remove.
18758 * tests/Makefile.am: Adjust.
18760 2001-12-10 Akim Demaille <akim@epita.fr>
18762 One structure for states is enough, even though theoretically
18763 there are LR(0) states and LALR(1) states.
18765 * src/lalr.h (state_t): Remove.
18766 (state_table): Be state_t **, not state_t *.
18767 * src/state.h (core, CORE_ALLOC): Rename as...
18768 (state_t, STATE_ALLOC): this.
18769 Add the LALR(1) members: shifts, reductions, errs.
18770 * src/LR0.c (state_table): Rename as...
18771 (state_hash): this, to avoid name clashes with the global
18773 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
18774 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
18776 2001-12-10 Akim Demaille <akim@epita.fr>
18778 Bison dumps core on bash.y.
18779 Reported by Pascal Bart.
18781 * src/warshall.c (bitmatrix_print): New.
18783 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
18784 j must be the outer loop.
18785 * tests/regression.at (Broken Closure): New.
18787 2001-12-05 Akim Demaille <akim@epita.fr>
18789 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
18791 Reported by Peter Hamorsky.
18793 2001-12-05 Akim Demaille <akim@epita.fr>
18795 * src/conflicts.c (err_table): Remove.
18796 (resolve_sr_conflict): Adjust.
18797 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
18799 (state_t.reductions, state_t.shifts): this.
18801 2001-12-05 Akim Demaille <akim@epita.fr>
18803 * src/reduce.c (reduce_grammar_tables): No longer disable the
18804 removal of useless rules via CPP but via `if (0)', so that the
18805 compiler still check the code is valid.
18806 For instance, it should have noticed `rline' no longer exists: use
18807 the `line' member of rule_t.
18808 * src/gram.c (dummy, rline): Remove, unused.
18810 2001-12-05 Akim Demaille <akim@epita.fr>
18812 * src/output.c (pack_vector): Use assert, not berror.
18813 * src/main.c (berror): Remove, unused.
18815 2001-12-05 Akim Demaille <akim@epita.fr>
18817 New experimental feature: if --verbose --trace output all the
18818 items of a state, not only its kernel.
18820 * src/print.c (print_core): If `trace_flag', then invoke closure
18821 before outputting the items of the state (print_core is no longer
18822 a correct name them).
18823 (print_results): Invoke new_closure/free_closure if needed.
18825 2001-12-05 Akim Demaille <akim@epita.fr>
18827 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
18828 * src/closure.c, src/closure.h (itemsetsize): Rename as...
18829 (nitemset): for consistency with the rest of the project.
18831 2001-12-05 Akim Demaille <akim@epita.fr>
18833 * src/closure.c (print_closure): Improve.
18834 (closure): Use it for printing input and output.
18836 2001-12-05 Akim Demaille <akim@epita.fr>
18838 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
18839 indexed by nonterminals.
18841 2001-12-05 Akim Demaille <akim@epita.fr>
18843 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
18845 * src/warshall.h: Remove accidental duplication of the content.
18847 2001-12-05 Akim Demaille <akim@epita.fr>

18859 2001-12-05 Akim Demaille <akim@epita.fr>
18861 * src/output.c (action_row): De-obfuscate
18862 using the good o' techniques: arrays not pointers, variable
18863 locality, BITISSET, RESETBIT etc.
18865 2001-12-05 Akim Demaille <akim@epita.fr>
18867 Pessimize the code to simplify it: from now on, all the states
18868 have a valid SHIFTS, which NSHIFTS is possibly 0.
18870 * src/LR0.c (shifts_new): Be global and move to..
18871 * src/state.c, src/state.h: here.
18872 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
18873 * src/print_graph: Adjust.
18875 2001-12-05 Akim Demaille <akim@epita.fr>
18877 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
18878 * src/conflicts.c: Use it.
18879 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
18880 incorrectly ``simplified''.
18882 2001-12-05 Akim Demaille <akim@epita.fr>
18884 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
18885 using the good o' techniques: arrays not pointers, variable
18886 locality, BITISSET, RESETBIT etc.
18888 2001-12-05 Akim Demaille <akim@epita.fr>
18890 * src/state.h (SHIFT_SYMBOL): New.
18891 * src/conflicts.c: Use it to deobfuscate.
18893 2001-12-05 Akim Demaille <akim@epita.fr>
18895 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
18896 (print_reductions): De-obfuscate using the good o' techniques:
18897 arrays not pointers, variable locality, BITISSET.
18899 2001-12-05 Akim Demaille <akim@epita.fr>
18901 * src/conflicts.c (print_reductions): Arrays, not pointers.
18904 2001-12-05 Akim Demaille <akim@epita.fr>

18912 2001-12-05 Akim Demaille <akim@epita.fr>
18914 * src/conflicts.c (print_reductions): Pessimize, but clarify.
18916 2001-12-05 Akim Demaille <akim@epita.fr>
18918 * src/conflicts.c (print_reductions): Improve variable locality.
18920 2001-12-05 Akim Demaille <akim@epita.fr>
18922 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
18923 * src/lalr.c: Use them.
18925 2001-12-05 Akim Demaille <akim@epita.fr>
18927 * src/LR0.c (augment_automaton): Formatting changes.
18928 Better variable locality.
18930 2001-12-05 Akim Demaille <akim@epita.fr>
18932 * src/lalr.c (matrix_print): New.
18933 (transpose): Use it.
18934 Use arrays instead of pointers.
18936 2001-12-05 Akim Demaille <akim@epita.fr>
18938 * src/lalr.c (maxrhs): Move to...
18939 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
18940 * src/lalr.c (build_relations): Adjust.
18942 2001-12-05 Akim Demaille <akim@epita.fr>
18944 * src/lalr.c (transpose): Free the memory allocated to the
18945 argument, as it is replaced by the results by the unique caller.
18946 (build_relations): Merely invoke transpose: it handles the memory
18948 Improve variable locality.
18949 Avoid variables used as mere abbreviations.
18950 (compute_lookaheads): Use arrays instead of pointers.
18952 2001-12-05 Akim Demaille <akim@epita.fr>
18954 * src/lalr.c (initialize_F): Improve variable locality.
18955 Avoid variables used as mere abbreviations.
18957 2001-12-05 Akim Demaille <akim@epita.fr>
18959 * src/derives.c (print_derives): Display the ruleno.
18960 * src/lalr.c (initialize_F, transpose): Better variable locality
18961 to improve readability.

18966 * src/lalr.c (traverse): Use arrays instead of pointers.
18968 2001-12-05 Akim Demaille <akim@epita.fr>
18970 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
18971 the handling of squeue.
18972 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
18974 2001-12-05 Akim Demaille <akim@epita.fr>
18976 Because useless nonterminals are now kept alive (instead of being
18977 `destroyed'), we now sometimes examine them, and store information
18978 related to them. Hence we need to know their number, and adjust
18979 memory allocations.
18981 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
18983 * src/LR0.c (allocate_itemsets): The memory allocated to
18984 `symbol_count' was used for two different purpose: once to count
18985 the number of occurrences of each symbol, and later reassigned to
18986 `shift_symbol', containing the symbol that can be shifted from a
18988 Deobfuscate, i.e., allocate, use and free `symbol_count' here
18990 (new_itemsets): Allocate `shift_symbol' here.
18991 (allocate_itemsets): symbol_count includes useless nonterminals.
18992 Make room for them.
18993 (free_storage): Use `free', not `XFREE', for pointers that cannot
18996 2001-12-05 Akim Demaille <akim@epita.fr>
18998 * src/nullable.c (set_nullable): Deobfuscate the handling of
19000 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19002 2001-12-05 Akim Demaille <akim@epita.fr>
19004 * src/gram.c, src/gram.h (ritem_print): New.
19005 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
19006 (This useless function was defined only to work around VMS linkers
19007 that can't handle compilation units with variables only).
19008 * src/reduce.c (dump_grammar): Use it to trace the construction of
19011 2001-12-04 Paul Eggert <eggert@twinsun.com>
19013 * src/bison.simple (union yyalloc): Change member names
19014 to be the same as the stack names.
19015 (yyparse): yyptr is now union yyalloc *, not char *.
19016 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
19017 and may generate better code on some machines.
19018 (yystpcpy): Use prototype if __STDC__ is defined, not just
19019 if __cplusplus is defined.
19021 2001-11-30 Akim Demaille <akim@epita.fr>
19023 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
19024 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
19025 Gettext doesn't compile cleanly, and dies with -Werror.
19026 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
19027 Include WARNING_CFLAGS here.
19028 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
19029 before being defined.
19031 2001-11-27 Paul Eggert <eggert@twinsun.com>
19033 * lib/quotearg.h (quotearg_n, quotearg_n_style):
19034 First arg is int, not unsigned.
19035 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
19036 (SIZE_MAX, UINT_MAX): New macros.
19037 (quotearg_n_options): Abort if N is negative.
19038 Avoid overflow check on hosts where size_t is 64 bits and int
19039 is 32 bits, as overflow is impossible there.
19040 Fix off-by-one typo that caused unnecessary reallocation.
19042 2001-11-29 Paul Eggert <eggert@twinsun.com>
19044 Name space cleanup in generated parser.
19046 * doc/bison.texinfo (Bison Parser): Discuss system headers
19047 and their effect on the user name space.
19049 * src/bison.simple:
19050 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
19051 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
19052 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
19054 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
19055 on user names when possible.
19057 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
19058 Simplify test for whather <alloca.h> exists.
19060 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
19062 (<stdio.h>): Include if YYDEBUG.
19064 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
19065 ! defined (yyoverflow) && ! defined (yymemcpy).
19067 (yymemcpy, yyparse): Rename local variables as needed so that
19068 they all begin with 'yy'.
19070 (yystrlen, yystpcpy): New functions.
19072 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
19075 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
19076 instead of relying on string.h functions. Use YYSTACK_ALLOC
19077 and YYSTACK_FREE instead of malloc and free.
19079 2001-11-30 Akim Demaille <akim@epita.fr>
19081 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
19082 before their first uses.
19083 (YYBISON, YYPURE): Move to the top of the output.
19085 2001-11-30 Akim Demaille <akim@epita.fr>
19087 * tests/reduce.at (Useless Nonterminals): Fix.
19089 2001-11-30 Akim Demaille <akim@epita.fr>
19091 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
19092 if body instead of `;' to pacify GCC's warnings.
19094 2001-11-30 Akim Demaille <akim@epita.fr>
19096 Instead of mapping the LHS of unused rules to -1, keep the LHS
19097 valid, but flag the rules as invalid.
19099 * src/gram.h (rule_t): `useful' is a new member.
19100 * src/print.c (print_grammar): Adjust.
19101 * src/derives.c (set_derives): Likewise.
19102 * src/reader.c (packgram, reduce_output): Likewise.
19103 * src/reduce.c (reduce_grammar_tables): Likewise.
19104 * tests/reduce.at (Underivable Rules, Useless Rules): New.
19106 2001-11-30 Akim Demaille <akim@epita.fr>
19108 * src/reduce.c (reduce_output): Formatting changes.
19109 * src/print.c (print_results, print_grammar): Likewise.
19110 * tests/regression.at (Rule Line Numbers)
19111 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
19113 2001-11-30 Akim Demaille <akim@epita.fr>
19115 * src/reduce.c (nonterminals_reduce): Instead of throwing away
19116 useless nonterminals, move them at the end of the symbol arrays.
19117 (reduce_output): Adjust.
19118 * tests/reduce.at (Useless Nonterminals): Adjust.
19120 2001-11-30 Akim Demaille <akim@epita.fr>
19122 * src/reduce.c: Various comment/formatting changes.
19123 (nonterminals_reduce): New, extracted from...
19124 (reduce_grammar_tables): here.
19125 (reduce_grammar): Call nonterminals_reduce.
19127 2001-11-29 Paul Eggert <eggert@twinsun.com>
19129 * src/bison.simple (YYSTACK_REALLOC): Remove.
19130 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
19131 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
19133 (union yyalloc): New type.
19134 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
19135 an arbitrary restriction on hosts where size_t is wider than int.
19137 (yyparse): Don't dump core if alloca or malloc fails; instead, report
19138 a parser stack overflow. Allocate just one block of memory for all
19139 three stacks, instead of allocating three blocks; this typically is
19140 faster and reduces fragmentation.
19142 Do not limit the number of items in the stack to a value that fits
19143 in 'int', as this is an arbitrary limit on hosts with 64-bit
19144 size_t and 32-bit int.
19146 2001-11-29 Marc Autret <autret_m@epita.fr>
19148 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
19149 of defining YYERROR_VERBOSE.
19150 [AT_DATA]: $4 is now out of C declarations in the prologue.
19152 2001-11-28 Marc Autret <autret_m@epita.fr>

19155 (parse_skel_decl): Use it.
19156 * src/lex.h: Add its prototype.
19157 * src/lex.c (literalchar): Become not static.
19159 2001-11-28 Marc Autret <autret_m@epita.fr>
19161 * src/output.h: And put its extern declaration here.
19162 * src/output.c (error_verbose): Define here.
19163 (prepare): Echo name modification.
19164 * src/getargs.h: Clean its extern declaration.
19165 * src/getargs.c (error_verbose_flag): Remove.
19166 (getargs): Remove case 'e'.

20956 New, from fileutils 4.0.37.

21008 introduces a guaranteed SEGV for semantic parsers.

21231 * src/main.c (main): Don't use `atexit' to register `done', since
21232 it no longer has to remove tmp files, just call `output_files'
21233 when there are no errors.
21235 2000-11-02 Akim Demaille <akim@epita.fr>

21309 (copy_guard): Adjust.
21311 2000-10-16 Akim Demaille <akim@epita.fr>
21313 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

21337 2000-10-04 Akim Demaille <akim@epita.fr>
21339 When a literal string is used to define two different tokens,
21340 `bison -v' segfaults.
21341 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
21343 * tests/regression.m4: New file.
21344 Include the core of the sample provided by Piotr Gackiewicz.
21345 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
21348 2000-10-04 Akim Demaille <akim@epita.fr>

21365 2000-10-02 Akim Demaille <akim@epita.fr>
21367 * src/derives.c, src/print.c, src/reduce.c: To ease the
21368 translation, move some `\n' out of the translated strings.
21370 2000-10-02 Akim Demaille <akim@epita.fr>
21372 The location tracking mechanism is precious for parse error
21373 messages. Nevertheless, it is enabled only when `@n' is used in
21374 the grammar, which is a different issue (you can use it in error
21375 message, but not in the grammar per se). Therefore, there should
21376 be another means to enable it.
21378 * src/getargs.c (getargs): Support `--locations'.
21379 (usage): Report it.
21380 * src/getargs.h (locationsflag): Export it.
21381 * src/lex.c (percent_table): Support `%locations'.
21382 * src/reader.c (yylsp_needed): Remove this variable, now replaced
21383 with `locationsflag'.
21384 * doc/bison.texinfo: Document `--locations' and `%locations'.
21386 * tests/calc.m4: Test it.
21388 For regularity of the names, replace each
21389 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
21390 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
21391 In addition replace each `flag' with `_flag'.
21393 2000-10-02 Akim Demaille <akim@epita.fr>
21395 Also test parse error messages, including with YYERROR_VERBOSE.
21397 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
21399 Use it to check the computations.
21400 Use it to check `nonassoc' is honored.
21401 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
21402 `--yyerror-verbose'.

21406 2000-10-02 Akim Demaille <akim@epita.fr>
21408 Test also `--verbose', `--defines' and `--name-prefix'. Testing
21409 the latter demonstrates a flaw in the handling of non debugging
21410 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
21411 was used in order to simplify:
21427 unfortunately this leads to a CPP conflict when
21428 `--name-prefix=foo' is used since it produces `#define yydebug
21431 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
21432 (YYDPRINTF): New macro.
21434 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
21436 Also test `--verbose', `--defines' and `--name-prefix'.

21440 Improve the readability of the produced parsers.
21442 * src/bison.s1: Formatting changes.
21443 Improve the comment related to the `$' mark.
21444 (yydefault): Don't fall through to `yyresume': `goto' there.
21445 * src/output.c (output_parser): When the `$' is met, skip the end
21447 New variable, `number_of_dollar_signs', to check there's exactly
21448 one `$' in the parser skeleton.
21450 2000-10-02 Akim Demaille <akim@epita.fr>
21452 * lib/xstrdup.c: New file, from the fileutils.
21453 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
21454 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
21455 instead of strlen + xmalloc + strcpy.
21456 * src/symtab.c (copys): Remove, use xstrdup instead.
21458 2000-10-02 Akim Demaille <akim@epita.fr>
21460 * src/gram.h (associativity): New enum type which replaces the
21461 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
21462 `right_assoc', `left_assoc' and `non_assoc'.
21463 Adjust all dependencies.
21464 * src/reader.c: Formatting changes.
21465 (LTYPESTR): Don't define it, use it as a literal in
21466 `reader_output_yylsp'.
21467 * src/symtab.h (symbol_class): New enum type which replaces the
21468 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
21469 `sunknown', `stoken and `snterm'.
21471 2000-10-02 Akim Demaille <akim@epita.fr>
21473 * src/getargs.c (fixed_outfiles): Rename as...
21474 (yaccflag): for consistency and accuracy.
21475 Adjust dependencies.
21477 2000-10-02 Akim Demaille <akim@epita.fr>
21479 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21480 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21481 difficult and introduced a lot of core dump. It turns out that
21482 Bison used an implementation of `xmalloc' based on `calloc', and
21483 at various places it does depend upon the initialization to 0. I
21484 have not tried to isolate the pertinent places, and all the former
21485 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
21486 someone should address this issue.
21488 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
21489 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

21499 * src/system.h: Include `assert.h'.
21501 2000-10-02 Akim Demaille <akim@epita.fr>
21503 * src/state.h (nstates, final_state, first_state, first_shift)
21504 (first_reduction): Move their exportation from here...

21506 Adjust dependencies.
21507 * src/getargs.c (statisticsflag): New variable.
21508 Add support for `--statistics'.

21515 * src/LR0.h: New file.
21518 2000-10-02 Akim Demaille <akim@epita.fr>

21545 Propagate its inclusion.
21546 * src/reduce.c: Topological sort and other formatting changes.
21547 (bool, TRUE, FALSE): Move their definition to...
21548 * src/system.h: here.
21550 2000-10-02 Akim Demaille <akim@epita.fr>
21552 * src/files.c: Formatting changes.
21553 (tryopen, tryclose, openfiles): Rename as...
21554 (xfopen, xfclose, open_files): this.
21555 (stringappend): static.

21579 * src/lalr.c: Formatting changes, topological sorting etc.
21581 2000-10-02 Akim Demaille <akim@epita.fr>
21583 * src/output.c (token_actions): Introduce a temporary array,
21584 YYDEFACT, that makes it possible for this function to use
21585 output_short_table.
21587 2000-10-02 Akim Demaille <akim@epita.fr>
21589 `user_toknums' is output as a `short[]' in `output.c', while it is
21590 defined as a `int[]' in `reader.c'. For consistency with the
21591 other output tables, `user_toknums' is now defined as a table of

21857 There is now a pseudo variable @$ (readble and writable), location
21858 of the lhs of the rule (by default ranging from the location of

22574 declaration to allow a multi-character symbol as an alias.
22575 (parse_thong_decl): New function.

22586 Revised and use multiple warnxxx functions to avoid using VARARGS1.
22587 (read_declarations): Improve the error message for
22588 an invalid character. Do not abort.
22589 (read_declarations, copy_guard, copy_action): Use
22590 printable_version to avoid unprintable characters in printed output.

22619 always contain the token. This includes growing the token
22620 buffer while reading an integer.
22621 (parse_percent_token): Replaced if-else statement with percent_table.
22622 (parse_percent_token): Added % declarations as another
22623 way to specify the flags -n, -l, and -r. Also added hooks for
22624 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
22625 major changes to files.c.
22626 (lex) Retain in the incoming stream a character following
22628 (skip_white_space, lex): Revised most error messages
22629 and changed fatal to warn to avoid aborting.
