26 Make yyparser::error public.
27 * data/lalr1.cc: here.
28 There is no good reason to keep it private (and it is convenient
29 to use it from the scanner for instance). It is already public in
32 2009-02-19 Akim Demaille <demaille@gostai.com>
37 2009-02-19 Akim Demaille <demaille@gostai.com>

123 2008-12-11 Akim Demaille <demaille@gostai.com>
126 * tests/local.mk: Replace "cd && testsuite" by "testsuite -C".
127 Solves problems when top_srcdir is an absolute path.

131 2008-12-11 Akim Demaille <demaille@gostai.com>
133 Simplify the i18n of the error messages.
134 * data/lalr1.cc: Comment changes.
135 * data/yacc.c (yysyntax_error): Rewrite, using a switch as in

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

173 * tests/local.mk (tests/atconfig): The rule was incorrect, but
174 remove it: now that there is no tests/Makefile.am, the top-level
175 Makefile properly updates atconfig when needed.
177 2008-12-07 Di-an Jan <dianj@freeshell.org>
179 Implement the FIXME that ends an user action with a semicolon
180 if it seems necessary.
181 * src/scan-code.l (flex rules section): Flag cpp directive from
182 any `#' to the first unescaped end-of-line. Semicolon is not
183 needed after `;', `{', '}', or cpp directives and is needed after
184 any other token (whitespaces and comments have no effect).
185 * tests/actions.at (Fix user actions without a trailing semicolon):
187 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add semicolons to
188 to make user actions complete statements.

211 (_AT_AMBIG_GLR_OUTPUT_WITH_LOC, _AT_GLR_STDERR)
212 (_AT_VERBOSE_GLR_STDERR): Expand to double-quoted strings,
213 since some of them contain unbalanced ')'.
215 2008-12-01 Akim Demaille <demaille@gostai.com>
217 Use b4_symbol for printers and destructors everywhere.
218 * data/bison.m4 (b4_symbol_action_location): New.
219 * data/c.m4 (b4_symbol_actions): Remove.
220 Adjust all callers to use by b4_symbol_foreach and the corresponding
221 b4_symbol_printer/destructor macro.
222 * data/glr.cc: Adjust.
223 * data/lalr1.java: Adjust the %destructor sanity check.
224 * src/output.c (symbol_code_props_output): Remove, we no longer
225 need the b4_symbol_printers/destructors tables.
227 2008-12-01 Akim Demaille <demaille@gostai.com>
230 * data/lalr1.cc, data/bison.m4 (b4_symbol_action): Use
233 2008-12-01 Akim Demaille <demaille@gostai.com>

237 (b4_symbol_action, b4_symbol_destructor, b4_symbol_printer)
238 (b4_symbol_case_, b4_symbol_foreach, b4_type_action_)
239 (b4_type_foreach): Move to...
240 * data/bison.m4: Here.
241 * data/lalr1.cc (b4_symbol_action): Specialize for C++: use
242 b4_symbol_value_template instead of b4_symbol_value.
244 2008-12-01 Akim Demaille <demaille@gostai.com>
246 b4_symbol/type_foreach.
247 * data/lalr1.cc (b4_symbol_foreach, b4_type_foreach): New.
250 2008-12-01 Akim Demaille <demaille@gostai.com>
252 Use the symbol properties to output the printer/destructor for lalr1.cc.
253 Instead of defining complex list of tuples to define various
254 properties of the symbols, we now prefer to define symbols as
255 "structs" in m4: using the symbol key (its number), and the
256 property name, b4_symbol gives it value. Use this to handle
257 destructors and printers.
259 * src/output.c (CODE_PROP): New.
260 (prepare_symbol_definitions): Use it to define the printer and
261 destructor related attributes of the symbols.
262 * data/lalr1.cc (b4_symbol_actions): Rename as...
263 (b4_symbol_action): this.
264 Use b4_symbol instead of 6 arguments.
265 (b4_symbol_printer, b4_symbol_destructor): New.
266 Use them instead of b4_symbol_actions.
268 2008-12-01 Akim Demaille <demaille@gostai.com>
270 Avoid capturing variables too easily.
271 * src/muscle_tab.h (MUSCLE_INSERT_BOOL, MUSCLE_OBSTACK_SGROW): Use
272 v__ and p__ instead of v and p.
274 2008-12-01 Akim Demaille <demaille@gostai.com>
276 Remove spurious empty line before syncline.
277 * data/bison.m4 (b4_syncline): Don't output an empty line before
280 2008-11-26 Akim Demaille <demaille@gostai.com>
282 Convert lib/Makefile.am into lib/local.mk.
283 The real problem is rather gnulib.mk, which itself is extracted
284 from a Makefile.am that gnulib expects to the "recursive". The
285 tool prefix-gnulib-mk converts such a gnulib.mk to be
286 non-recursive. Also, some AC_SUBST variables need to be adjusted.
288 * etc/prefix-gnulib-mk: New.
289 * bootstrap (slurp): Use it to convert further gnulib.mk.
290 No longer try to avoid re-creation of lib/gnulib.mk as the changes
292 * lib/Makefile.am: Rename as...
293 * lib/local.mk: this.
294 Adjust to be prefixed.
295 * Makefile.am, configure.ac: Adjust.
296 * src/local.mk (AM_CPPFLAGS): Extend it, don't define it.
298 2008-11-26 Akim Demaille <demaille@gostai.com>

302 (TESTSUITEFLAGS, AUTOTESTFLAGS): these to compy with the GCS.
303 Reported by Eric Blake.
305 2008-11-26 Akim Demaille <demaille@gostai.com>
307 Use b4_parser_tables_define in glr.cc.
308 * data/glr.c: Use b4_parser_tables_define instead of defining the
309 (deterministic integral) tables by hand.
311 2008-11-26 Akim Demaille <demaille@gostai.com>
313 Use b4_parser_tables_define in Java.
314 * data/java.m4 (b4_typed_parser_table): Rename as...
315 (b4_typed_parser_table_define): this, for consistency.
316 Accept a comment as $4.
318 (b4_integral_parser_table): Rename as...

333 (b4_table_define, b4_table_declare): Rename as...
334 (b4_integral_parser_table_define)
335 (b4_integral_parser_table_declare): these.
336 (yyrline_): Move the comment where it is actually used.
337 * data/yacc.c: Adjust.
338 (yyrline): Use b4_integral_parser_table_define.
340 2008-11-26 Akim Demaille <demaille@gostai.com>
343 * src/parse-gram.h, src/parse-gram.c: Regen.
345 2008-11-26 Akim Demaille <demaille@gostai.com>
347 Factor the generation of the (integral) tables bw yacc.c and lalr1.cc.

352 * data/lalr1.cc: Use them.
353 * data/c.m4 (b4_table_define): New.
354 * data/yacc.c: Use b4_tables_define instead of output the tables
356 * tests/regression.at (Web2c Actions): Adjust the expected output,
357 the order of the tables changed.
359 2008-11-26 Akim Demaille <demaille@gostai.com>
361 Get rid of (yy)rhs and (yy)prhs.
362 These tables are no longer needed in the parsers, and they don't seem to
363 be useful. They are not documented either.
365 * src/output.c (prepare_rules): Get rid of rhs and prhs.
366 Adjust the computation of (yy)r2.
368 2008-11-26 Akim Demaille <demaille@gostai.com>
370 Rule length is unsigned.
371 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
373 2008-11-26 Akim Demaille <demaille@gostai.com>
375 Get rid of lalr1-split.cc.
376 It was no longer maintainer.
378 * data/lalr1-split.cc: Remove.
379 * etc/bench.pl.in (bench_fusion_parser): Remove.
382 2008-11-26 Akim Demaille <demaille@gostai.com>
384 Use yy* consistently.
385 * data/glr.c: Now that yyrhs no longer exists as a global
386 variable, rename local "rhs" variables into "yyrhs" for
389 2008-11-25 Akim Demaille <demaille@gostai.com>
391 Get rid of yyrhs and yyprhs in glr.c.
392 * data/glr.c (yyrhs, yyprhs): Remove.
393 Instead, use the state stack and yystos.
395 2008-11-25 Akim Demaille <demaille@gostai.com>
398 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
399 as an Autotest keyword.
401 2008-11-25 Akim Demaille <demaille@gostai.com>
403 Prefer TESTSUITE_FLAGS.
404 TESTSUITEFLAGS is barely readable.
406 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
407 for backward compatibility.
408 Use the former instead of the latter.
410 2008-11-25 Akim Demaille <demaille@gostai.com>
412 Get rid of yyrhs and yyprhs in larl1.java.
413 * data/lalr1.java (yyrhs_, yyprhs_): Remove.
414 (yy_reduce_print): Rather, use yystos_ and the state stack.
416 2008-11-25 Akim Demaille <demaille@gostai.com>
420 2008-11-25 Akim Demaille <demaille@gostai.com>
422 Get rid of yyrhs and yyprhs in yacc.c.
423 They were used to get the symbol types, given a rule number, when
424 displaying the top of the stack before a reduction. But the
425 symbol type is available from the state stack. This has two be
426 benefits: two tables less in the parser (making it smaller), and a
427 more consistent use of the three stacks which will help to fuse
430 * data/yacc.c (yyprhs, yyrhs): Remove.
431 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
432 (yy_reduce_print): Take yyssp as argument.
433 Use it, together with yystos, to get the symbol type.
434 * tests/regression.at (Web2c Report): Remove these tables from the
437 2008-11-25 Akim Demaille <demaille@gostai.com>
440 The point is to factor the generation of the tables across skeletons.
441 This is language dependant.
443 * data/c.m4 (b4_comment_): New.
444 Should be usable to define how to generate tables independently of
447 (b4_comment): Bounce to b4_c_comment.
448 Now support $2 = [PREFIX] for indentation.
449 * data/lalr1.cc (b4_table_declare): Don't output a comment if
451 Indent it properly when there is one.
452 Output the ending semicolon.
453 (b4_table_define): Space changes.
454 Output the ending semicolon.
455 (b4_tables_map): New.
456 Use it twice instead of declaring and defining the (integral)
459 2008-11-25 Akim Demaille <demaille@gostai.com>
462 * data/lalr1.cc (b4_table_declare): New.
463 Use it to declare the tables defined with b4_table_define.

573 (Examples): Don't abbreviate node names.
574 (LocalWords): Remove abbreviations.
575 (Copying): Make description a sentence.
576 (Java Action Features): Remove period to match the rest of menu.

621 2008-11-15 Akim Demaille <demaille@gostai.com>
623 Support parametric types.
625 There are two issues to handle: first scanning nested angle
626 bracket pairs to support types such as std::pair< std::string,
627 std::list<std::string> > >.
629 Another issue is to address idiosyncracies of C++: do not glue two
630 closing angle brackets together (otherwise it's operator>>), and
631 avoid sticking blindly a TYPE to the opening <, as it can result
632 in '<:' which is a digraph for '['.
634 * src/scan-gram.l (brace_level): Rename as...
637 Implement support for complex tags.
640 * data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)
641 (b4_symbol_variant): Leave space around types as parameters.
642 * examples/variant.yy: Use nested template types and leading ::.
643 * src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):
645 (TAG, TAG_ANY, TAG_NONE, tag.opt): these.
646 * tests/c++.at: Test parametric types.
648 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
651 This is not sufficient, but we test at least that the make_SYMBOL
652 interface is not affected by token.prefix. A more general test
653 will be implemented when the support of token.prefix is generalized
656 * tests/c++.at: One more variant test, using token.prefix.

730 Move sc_tight_scope into maint.mk.
731 It does not work, and I don't know how it was supposed to work: it
732 seems to be looking for sources in the build tree. I just moved
733 it at a better place, fixing it is still required.
735 * src/local.mk (echo): Remove.

754 * maint.mk (sc_tight_scope): Disable.
755 It used to bounce to the version in src/Makefile.am which is now
756 part of this very Makefile.
757 * Makefile.am, configure.ac: Adjust.
758 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
759 include "..." to find files "here": we are no longer in src/, so
760 qualify the includes with src/.
761 * doc/Makefile.am (PREPATH): No longer include the top_builddir
763 (.x.1): Adjust to be able to create src/foo from the top level
764 Makefile, instead of going bounce to src/Makefile the creation of

791 examples/calc++/Makefile.am might be interesting to keep as is, since
792 it is an example in itself.

797 * Makefile.am, configure.ac: Adjust.
799 2008-11-15 Akim Demaille <demaille@gostai.com>
801 Remove build-aux/Makefile.am.
802 Recursive Makefiles are really way too slow, let's get rid of some of

808 * Makefile.am, configure.ac: Adjust.
810 2008-11-15 Akim Demaille <demaille@gostai.com>
812 Provide convenience constructors for locations and positions.
813 * data/location.cc (position::position): Accept file, line and
814 column as arguments with default values.
815 Always qualify initial line and column literals as unsigned.
816 (location::location): Provide convenience constructors.
818 2008-11-15 Akim Demaille <demaille@gostai.com>
820 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
822 Using template buys us nothing, and makes it uselessly complex to
823 construct a symbol. Besides, it could not be generalized to other
824 languages, while make_FOO would work in C/Java etc.
826 * data/lalr1.cc (b4_symbol_): New.
828 (b4_symbol_constructor_declaration_)
829 (b4_symbol_constructor_definition_): Instead of generating
830 specializations of an overloaded template function, just generate
831 several functions whose names are forged from the token names
832 without the token.prefix.
833 (b4_symbol_constructor_declarations): Generate them for all the
834 symbols, not just by class of symbol type, now that instead of
835 specializing a function template by the token, we generate a
836 function named after the token.
837 (b4_symbol_constructor_specialization_)
838 (b4_symbol_constructor_specializations): Remove.
839 * etc/bench.pl.in: Adjust to this new API.
841 2008-11-13 Akim Demaille <demaille@gostai.com>
843 %define token.prefix.
844 Provide a means to add a prefix to the name of the tokens as
845 output in the generated files. Because of name clashes, it is
846 good to have such a prefix such as TOK_ that protects from names
847 such as EOF, FILE etc. But it clutters the grammar itself.
849 * data/bison.m4 (token.prefix): Empty by default.
850 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
851 * data/lalr1.cc (b4_symbol): Ditto.
853 2008-11-13 Akim Demaille <demaille@gostai.com>
855 Compute at M4 time some of the subtractions.
856 * data/lalr1.cc (b4_subtract): New.
857 (b4_rhs_data): Use it.
859 2008-11-13 Akim Demaille <demaille@gostai.com>
862 This allows the user to get the type of a token returned by yylex.
864 * data/lalr1.cc (symbol::token): New.
865 (yytoknum_): Define when %define lex_symbol, independently of
867 (yytoken_number_): Move into...
868 (symbol::token): here, since that's the only use.
869 The other one is YYPRINT which was not officially supported
870 by lalr1.cc, and anyway it did not work since YYPRINT uses this
871 array under a different name (yytoknum).
873 2008-11-13 Akim Demaille <demaille@gostai.com>
876 * TODO (YYERRCODE): Mention the case of $undef.
878 2008-11-13 Akim Demaille <demaille@gostai.com>

883 2008-11-13 Akim Demaille <demaille@gostai.com>
886 * data/lalr1.cc, data/yacc.c: Fix the description of the
887 yytranslate and yytoknum tables.
889 2008-11-13 Akim Demaille <demaille@gostai.com>
891 Define make_symbol in the header.
892 To reach good performances these functions should be inlined (yet
893 this is to measure precisely). To this end they must be available
896 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
897 location_type with the class name.
898 Since will now be output in the header, declare "inline".
899 No longer use b4_symbol_constructor_specializations, but
900 b4_symbol_constructor_definitions in the header.
901 Don't call it in the *.cc file.
903 2008-11-13 Akim Demaille <demaille@gostai.com>
905 Define yytranslate in the header for lex_symbol.
906 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
907 into the header file when using %define lex_symbol.
908 (yytranslate_): Declare inline.
910 2008-11-13 Akim Demaille <demaille@gostai.com>
912 Define the constructors of symbol_type in
913 b4_symbol_constructor_definitions.
914 The constructors are called by the make_symbol functions, which a
915 forthcoming patch will move elsewhere. Hence the interest of
916 putting them together.
918 The stack_symbol_type does not need to be moved, it is used only
921 * data/lalr1.cc: Move symbol_type and symbol_base_type
923 (b4_symbol_constructor_definitions): here.
926 2008-11-13 Akim Demaille <demaille@gostai.com>
928 Make it easier to move the definition of yytranslate_.
929 Forthcoming changes will make it possible to use yytranslate_
930 from outside the parser implementation file.
932 * data/lalr1.cc (b4_yytranslate_definition): New.
935 2008-11-13 Akim Demaille <demaille@gostai.com>
937 Remove useless class specification.
938 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
939 to refer to the class name to use a type defined by the class for
940 arguments of member functions.
942 2008-11-13 Akim Demaille <demaille@gostai.com>
944 Finer input type for yytranslate.
945 This patch is debatable: the tradition expects yylex to return an int
946 which happens to correspond to token_number (which is an enum). This
947 allows for instance to return characters (such as '*' etc.). But this
948 goes against the stronger typing I am trying to have with the new
949 lex interface which return a symbol_type. So in this case, feed
950 yytranslate_ with a token_type.
952 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
955 2008-11-13 Akim Demaille <demaille@gostai.com>
957 Honor lex-params in %define lex_symbol mode.
958 * data/lalr1.cc: Use b4_lex_param.
960 2008-11-13 Akim Demaille <demaille@gostai.com>
963 * src/output.c (symbol_definitions_output): Rename symbol
964 attributes type_name and has_type_name as type and has_type.
965 * data/lalr1.cc: Adjust uses.
967 2008-11-13 Akim Demaille <demaille@gostai.com>
969 Use b4_type_names for the union type.
970 The union used to compute the size of the variant used to iterate
971 over the type of all the symbols, with a lot of redundancy. Now
972 iterate over the lists of symbols having the same type-name.
974 * data/lalr1.cc (b4_char_sizeof_): New.
975 (b4_char_sizeof): Use it.
976 Adjust to be called with a list of numbers instead of a single
978 Adjust its caller for new-line issues.
980 2008-11-13 Akim Demaille <demaille@gostai.com>
982 Define the "identifier" of a symbol.
983 Symbols may have several string representations, for instance if
984 they have an alias. What I call its "id" is a string that can be
985 used as an identifier. May not exist.
987 Currently the symbols which have the "tag_is_id" flag set are
988 those that don't have an alias. Look harder for the id.
990 * src/output.c (is_identifier): Move to...
991 * src/symtab.c (is_identifier): here.
992 * src/symtab.h, src/symtab.c (symbol_id_get): New.
993 * src/output.c (symbol_definitions_output): Use it to define "id"
995 Remove the definition of "tag_is_id".
996 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
997 "tag_is_id" were used to produce code.
998 We still use "tag" for documentation.
1000 2008-11-11 Akim Demaille <demaille@gostai.com>
1002 Locations are no longer required by lalr1.cc.
1003 * data/lalr1.cc (_b4_args, b4_args): New.
1004 Adjust all uses of locations to make them optional.
1005 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
1006 (AT_CHECK_NAMESPACE): Check the use of locations.
1007 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
1008 without locations with lalr1.cc.
1010 * tests/output.at: Check lalr1.cc with and without location
1012 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
1013 Don't use locations.
1015 2008-11-11 Akim Demaille <demaille@gostai.com>
1018 * tests/local.at (AT_FULL_COMPILE): New.
1019 * tests/actions.at, tests/calc.at, tests/regression.at: Use it.
1021 2008-11-11 Akim Demaille <demaille@gostai.com>
1023 Support parens in calc++.
1024 * doc/bison.texinfo (Calc++ Scanner, Calc++ Parser): Support parens.
1025 * examples/calc++/test (run): Check the expected output.

1047 Support i18n of the parse error messages.
1048 * TODO (lalr1.cc/I18n): Remove.
1049 * data/lalr1.cc (yysyntax_error_): Support the translation of the
1050 error messages, as done in yacc.c.
1051 Stay within the yy* pseudo namespace.

1060 Make it possible to return a symbol_type from yylex.

1098 Let yytranslate handle the eof case.
1099 * data/lalr1.cc (yytranslate_): Handle the EOF case.
1101 No longer expect yychar to be equal to yyeof_, rather, test the
1102 lookahead's (translated) kind.
1104 2008-11-11 Akim Demaille <demaille@gostai.com>
1106 yychar cannot be empty in yyerrlab.
1107 * TODO (yychar == yyempty_): New.
1108 * data/lalr1.cc: Remove the handling of this case.
1109 This eases forthcoming changes related to yychar and yytranslate.
1111 2008-11-11 Akim Demaille <demaille@gostai.com>
1113 Bench: syntactic sugar for %define/#define.
1114 * etc/bench.pl.in (parse_dirs): Support %d and #d with arguments.
1115 (&bench_push_parser, bench_variant_parser): Use this feature.
1119 2008-11-11 Akim Demaille <demaille@gostai.com>
1121 Less memory pressure on the "list" bench.
1122 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
1123 the values, to limit memory pressure.
1125 2008-11-11 Akim Demaille <demaille@gostai.com>
1127 Introduce make_symbol.
1128 make_symbol provides a means to construct a full symbol (kind,
1129 value, location) in a single shot. It is meant to be a Symbol
1130 constructor, parameterized by the symbol kind so that overloading
1131 would prevent incorrect kind/value pairs. Unfortunately
1132 parameterized constructors do not work well in C++ (unless the
1133 parameter also appears as an argument, which is not acceptable),
1134 hence the use of a function instead of a constructor.
1136 * data/lalr1.cc (b4_symbol_constructor_declaration_)
1137 (b4_symbol_constructor_declarations)
1138 (b4_symbol_constructor_specialization_)
1139 (b4_symbol_constructor_specializations)
1140 (b4_symbol_constructor_definition_)
1141 (b4_symbol_constructor_definitions): New.
1142 Use them where appropriate to generate declaration, declaration of
1143 the specializations, and implementations of the templated
1144 overloaded function "make_symbol".
1145 (variant::variant): Always define a default ctor.
1146 Also provide a copy ctor.
1147 (symbol_base_type, symbol_type): New ctor overloads for value-less
1149 (symbol_type): Now public, so that functions such as yylex can use
1152 2008-11-11 Akim Demaille <demaille@gostai.com>
1154 Inform m4 whether a tag is a valid id.
1155 * src/output.c (is_identifier): New.
1156 (symbol_definitions_output): Use it to define tag_is_id.
1157 But maybe this should be done at m4 level?

1161 Test 214 was failing: it greps with a pattern containing [ ]*
1162 which obviously meant to catch spaces and tabs, but contained only
1163 spaces. Tabulations in sources are a nuisance, so to simplify the
1164 matter, get rid of all the tabulations in the Java sources. The
1165 other skeletons will be treated equally later.
1167 * data/java.m4, data/lalr1.java: Untabify.
1168 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
1169 tabulations are no longer generated.

1262 For instance, how can a * b / c be parsed if * is %left and / is
1264 (YYERRORCODE, YYFAIL, YYBACKUP): New.
1266 2008-11-10 Akim Demaille <demaille@gostai.com>
1270 2008-11-10 Akim Demaille <demaille@gostai.com>
1272 More information about the symbols.
1273 * src/output.c (type_names_output): Document all the symbols,
1274 including those that don't have a type-name.
1275 (symbol_definitions_output): Define "is_token" and

1284 2008-11-10 Akim Demaille <demaille@gostai.com>

1305 2008-11-10 Akim Demaille <demaille@gostai.com>

1347 2008-11-10 Akim Demaille <demaille@gostai.com>
1349 Change the handling of the symbols in the skeletons.
1350 Before we were using tables which lines were the symbols and which
1351 columns were things like number, tag, type-name etc. It is was
1352 difficult to extend: each time a column was added, all the numbers had
1353 to be updated (you asked for colon $2, not for "tag"). Also, it was
1354 hard to filter these tables when only a subset of the symbols (say the
1355 tokens, or the nterms, or the tokens that have and external number
1356 *and* a type-name) was of interest.
1358 Now instead of monolithic tables, we define one macro per cell. For
1359 instance "b4_symbol(0, tag)" is a macro name which contents is
1360 self-decriptive. The macro "b4_symbol" provides easier access to
1363 * src/output.c (type_names_output): Remove.
1364 (symbol_numbers_output, symbol_definitions_output): New.
1365 (muscles_output): Call them.

1407 2008-11-10 Akim Demaille <demaille@gostai.com>
1409 Add %precedence support.
1410 Unfortunately it is not possible to reuse the %prec directive. This
1411 is because to please POSIX, we do not require to end the rules with a
1412 semicolon. As a result,
1416 is ambiguous: either a rule which precedence is that of baz, or a rule,
1417 and then a declaration of the precedence of the token baz.
1419 * doc/bison.texinfo: Document %precedence.
1420 (Precedence Only): New.
1421 * src/assoc.h, src/assoc.c (precedence_assoc): New.

1484 (&bench_grammar): Use it.
1485 (&bench_list_grammar): New, to provide access to the "variant"
1488 (getopts): Support -d, --directive.
1490 2008-11-09 Akim Demaille <demaille@gostai.com>

1517 Rename data_type and stack_symbol_type.
1518 * data/lalr1.cc (data_type): Rename as...

1521 2008-11-09 Akim Demaille <demaille@gostai.com>
1523 Handle semantic value and location together.
1524 * data/lalr1.cc (b4_symbol_actions): Bounce $$ and @$ to

1545 2008-11-09 Akim Demaille <demaille@gostai.com>
1547 Rely on the state stack to display reduction traces.
1548 To display rhs symbols before a reduction, we used information
1549 about the rule reduced, which required the tables yyrhs and
1550 yyprhs. Now use rely only on the state stack to get the same
1553 * data/lalr1.cc (b4_rhs_data, b4_rhs_state): New.

1677 2008-11-07 Akim Demaille <demaille@gostai.com>
1679 Add "%define assert" to variants.
1680 This is used to help the user catch cases where some value gets
1681 ovewritten by a new one. This should not happen, as this will
1684 Unfortunately this uncovered a bug in the C++ parser itself: the
1685 lookahead value was not destroyed between two calls to yylex. For
1686 instance if the previous lookahead was a std::string, and then an int,
1687 then the value of the std::string was correctly taken (i.e., the
1688 lookahead was now an empty string), but std::string structure itself
1691 This is now done in variant::build(other&) (which is used to take the
1692 value of the lookahead): other is not only stolen from its value, it
1693 is also destroyed. This incurs a new performance penalty of a few
1694 percent, and union becomes faster again.
1696 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.
1697 (b4_variant_if): New.
1698 (variant::built): New.

1973 2008-11-03 Akim Demaille <demaille@gostai.com>
1975 Fuse the three stacks into a single one.
1977 In order to make it easy to perform benchmarks to ensure that
1978 there are no performance loss, lalr1.cc is forked into
1979 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
1982 Meanwhile, to make sure that lalr1-fusion.cc is correctly
1983 exercized by the test suite, the user must install a symbolic link
1984 from lalr1.cc to it.
1986 Instead of having three stacks (state, value, location), use a
1987 stack of triples. This considerably simplifies the code (and it
1988 will be easier not to require locations as currently does the C++
1989 parser), and also gives a 10% speedup according to
1990 etc/bench (probably mainly since memory allocation is done once
1991 instead of three times).
1993 Another motivation is to make it easier to destruct properly
1994 semantic values: now that they are bound to their state (hence
1995 symbol type) it will be easier to call the appropriate destructor.
1997 These changes should probably benefit the C parser too.
1999 * data/lalr1.cc: Copy as...
2000 * data/lalr1-fusion.cc: this new file.
2001 (b4_rhs_value, b4_rhs_location): New definitions overriding those
2003 (state_stack_type, semantic_stack_type, location_stack_type)
2004 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
2005 (data_type, stack_type, yystack_): New.
2006 (YYLLOC_DEFAULT, yypush_): Adjust.
2007 (yyerror_range): Now based on data_type, not location_type.
2009 2008-11-03 Akim Demaille <demaille@gostai.com>
2011 Push the state, value, and location at the same time.
2012 This is needed to prepare a forthcoming patch that fuses the three
2015 * data/lalr1.cc (parser::yypush_): New.
2016 (parser::yynewstate): Change the semantics: instead of arriving to
2017 this label when value and location have been pushed, but yystate
2018 is to be pushed on the state stack, now the three of them must
2019 have been pushed before. yystate still must be the new state.
2020 This allows to use yypush_ everywhere instead of individual
2021 handling of the stacks.
2023 2008-11-03 Akim Demaille <demaille@gostai.com>
2025 Prefer references to pointers.
2026 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
2027 definition to use references instead of pointers.
2028 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
2029 Take the value and location as references.
2032 2008-11-03 Akim Demaille <demaille@gostai.com>
2034 stack::size instead of stack::height.
2035 * data/lalr1.cc (stack::height): Rename as...
2036 (stack::size): this.
2037 Fix the output type.
2040 2008-11-03 Akim Demaille <demaille@gostai.com>
2042 Use variants to support objects as semantic values.
2043 This patch was inspired by work by Michiel De Wilde. But he used
2044 Boost variants which (i) requires Boost on the user side, (ii) is
2045 slow, and (iii) has useless overhead (the parser knows the type of
2046 the semantic value there is no reason to duplicate this
2047 information as Boost.Variants do).
2049 This implementation reserves a buffer large enough to store the
2050 largest objects. yy::variant implements this buffer. It was
2051 implemented with Quentin Hocquet.
2053 * src/output.c (type_names_output): New.
2054 (output_skeleton): Invoke it.
2055 * data/c++.m4 (b4_variant_if): New.

2059 (b4_char_sizeof, yy::variant): New.
2060 (parser::parse): If variants are requested, define
2061 parser::union_type, parser::variant, change the definition of
2062 semantic_type, construct $$ before running the user action instead
2063 of performing a default $$ = $1.
2064 * examples/variant.yy: New.
2065 Based on an example by Michiel De Wilde.
2067 2008-11-03 Akim Demaille <demaille@gostai.com>
2069 Parameterize the extraction of semantic values.
2070 To make future changes easier, no longer rely on ".TYPE" being the
2071 way to get a semantic value.
2073 * data/c.m4 (b4_symbol_value): New.
2075 * data/c++.m4, data/yacc.c: Use it.
2076 * data/glr.c: Use b4_symbol_value.

2109 * NEWS: Say it's experimental.

2111 recommend it over %skeleton for now.

2185 * src/files.c (compute_file_name_parts): When the user specifies
2186 --output but not --file-prefix, extract the directory prefix from the

2370 * data/m4sugar/m4sugar.m4 (changeword): Nuke.
2371 (m4_prepend): Remove, as it is unused and inherently quadratic,
2372 whereas m4_append is linear in newer m4.
2373 (m4_mkstemp): New builtin.

2425 Fix dependence on computed configure variables.
2426 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not

2429 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2431 2008-07-20 Joel E. Denny <jdenny@ces.clemson.edu>

2453 * NEWS (2.3b+): Rename to...
2454 (?.?): ... this because we're dropping the "+" version naming scheme,
2455 but, in general, we still can't be sure of our next release name.
2456 * bootstrap: Add a quick hack to remove from .gitignore the
2457 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
2458 entry. This should really be fixed in gnulib instead.
2459 * bootstrap.conf (gnulib_modules): Add gnumakefile.
2460 * configure.ac (AC_INIT): Set version name by invoking
2461 build-aux/git-version-gen.

2491 Fix some .gitignore and .cvsignore problems.
2492 * bootstrap (insert_sorted_if_absent): Replace all uses with...
2493 (insert_vc_ignore): ... this new function, which prepends `/' to all
2494 .gitignore entries before passing them to insert_sorted_if_absent.
2495 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
2496 .cvsignore files are maintained even though Bison developers run
2497 bootstrap while using Git.
2498 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
2501 * .gitignore (/*.patch *.log log patches applied): Remove, broken and
2502 unneeded. Reported by Eric Blake.

2514 * lib/.gitignore, lib/.cvsignore (/unsetenv.c): Add.
2515 * m4/.gitignore, m4/.cvsignore (/environ.m4): Add.
2517 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
2518 the first argument because it may become position-dependent, and unset
2519 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
2520 Add comments explaining these issues in more detail.
2522 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>
2524 Add .gitignore everywhere based on .cvsignore.

2555 2008-05-23 Joel E. Denny <jdenny@ces.clemson.edu>
2557 * HACKING: Don't say don't mention HACKING in the ChangeLog. We've
2558 been doing it for years.
2559 (Test suite): Mention maintainer-push-check and maintainer-xml-check.
2560 (Release Procedure): Add FIXME about make alpha being unmaintained.

2578 2008-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
2580 * THANKS: Add Eric Blake.
2582 2008-04-23 Eric Blake <ebb9@byu.net>
2584 Revert prior patch, by working around autoconf regression.
2585 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
2586 ("Output file name: ("): Uncomment test.
2587 ("Output file name: )"): Likewise.
2588 Based on an idea from Noah Misch.
2590 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>

2593 2.61. Reported by Juan Manuel Guerrero at
2594 <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
2595 * tests/output.at ("Output file name: ("): Comment out test case for
2597 ("Output file name: )"): Likewise.
2599 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
2601 * GNUmakefile: Update git-version-gen invocation so make dist
2604 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
2606 Update to the current gnulib CVS repository, and fix trigraph handling
2608 * bootstrap: Update gnulib CVS repository URL.
2609 (symlink_to_dir): Encapsulate the code that guarantees the destination
2610 directory exists into...
2611 (check_dst_dir): ... this new function, and...
2612 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
2613 fail when copying files into lib/uniwidth/.
2614 * src/output.c (prepare_symbols): When writing yytname muscles, where
2615 symbol names will be encoded in C-string literals, tell quotearg to
2616 escape trigraphs. This used to be the default in gnulib.
2617 * tests/regression.at (Token definitions): Because of the change in
2618 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
2619 escapes trigraphs in symbol names. Thus, yytname no longer has
2620 trigraphs unnecessarily doubly escaped. Update test case output.
2621 Extend test case to be sure Bison's own error messages will no longer
2622 have trigraphs in symbol names unnecessarily escaped once.
2624 2008-04-20 Joel E. Denny <jdenny@ces.clemson.edu>
2626 Fix make dist infinite loop reported by Juan Manuel Guerrero at

2636 * NEWS (2.3a+): Mention that -g now takes an argument.
2637 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
2638 consistency. Update the -g and -x entries now that they take
2639 arguments. Use brackets to indicate optional arguments.
2640 * src/getargs.c (usage): Explain the relationship between arguments of
2641 long and short options more completely. Document --defines and -d
2642 separately since the former takes an argument but, for POSIX Yacc, the
2644 (short_options): Let -W take an optional argument like --warnings.
2645 (getargs): Sort cases.

2659 -g and -x take optional arguments, just like their long options.
2660 * build-aux/cross-options.pl: Use /x to make the regexp easier to
2662 Fix the handling of $opt which resulted in all the argument to be
2663 considered as optional.
2665 2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>
2667 * NEWS (2.3a+): Don't say %language is experimental. Mention Java and
2668 say its interface is experimental.
2669 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
2671 (Bison Options): In the -L and --language entry, mention Java.

2699 Fix impure push parser compile error reported by Bob Rossi at
2700 <http://lists.gnu.org/archive/html/help-bison/2008-02/msg00023.html>.
2701 * data/yacc.c: Clean up whitespace in the output a little.
2702 (yypstate_allocated): Define for impure push parsers regardless of
2703 whether the pull interface is also requested.
2704 * tests/push.at (Push Parsing: Multiple impure instances): Extend to
2705 check impure push parsers without the pull interface.
2707 * data/yacc.c (yypstate_new): Don't try to invoke yyerror since
2708 yyerror takes arguments specified by %parse-param while yypstate_new

3301 (C++ Bison Interface): Mention `%define namespace' instead of
3303 (Table of Symbols): Remove the `%define push_pull' entry. The %define

3399 parsing requests here...
3400 * data/yacc.c: ... hack this to switch to push.c any time

3402 will go away when we mv push.c yacc.c.
3403 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
3404 push parsing is not supported since unused %define variables are

3615 Get rid of broken %no-parser, -n, and --no-parser implementation and
3617 * TODO: Don't mention them.
3618 * doc/bison.1: Likewise.
3619 * doc/bison.texinfo (Decl Summary): Likewise.
3620 (Bison Options): Likewise.
3621 (Option Cross Key): Likewise.
3622 * src/getargs.c (no_parser_flag): Remove global variable.
3623 (usage): Don't print description of -n and --no-parser.
3624 (long_options): Remove --no-parser entry here.
3625 (getargs): Remove -n case in the switch here.
3626 * src/getargs.h (no_parser_flag): Remove extern.
3627 * tests/regression.at (Web2c Actions): Remove comment that mentions
3630 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
3632 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
3633 name user variables starting with `yy'. Just pass NULL instead of a
3634 dummy local &yylval to yypush_parse.
3635 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
3638 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
3640 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
3641 true since it's then always used regardless of whether yyoverflow is
3642 defined. Reported by Christian Burger at
3643 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
3644 * THANKS: Add Christian Burger.
3646 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3647 node names: say "Decl Summary" not "Bison Declaration Summary".
3649 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
3651 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
3652 determine whether this function has already complained about an invalid
3653 value for a %define boolean variable, don't check whether Bison has
3654 ever examined the value. As written, the check was a tautology.
3655 Instead, record and check for this complaint using a separate muscle.
3657 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
3659 Fix push parsing memory leak reported by Brandon Lucia at
3660 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
3661 * THANKS: Add Brandon Lucia.
3662 * data/push.c (yypstate_delete): Free the stack if it was reallocated
3663 but the parse never completed and thus freed it.
3664 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
3665 * tests/testsuite.at: Include push.at.
3666 * test/push.at: New.
3667 (Push Parsing: Memory Leak for Early Deletion): New test case.
3669 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
3671 Improve handling of multiple S/R conflicts in the same state and of S/R
3672 conflicts involving multiple reductions.
3673 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
3674 set for a state here or Bison will abort if it is reassigned on a
3675 later conflicted reduction in the same state.
3676 Similarly, don't finalize and assign the solved conflicts report here
3677 or it will be lost if it is reassigned on a later conflicted reduction
3679 (set_conflicts): Instead, assign them both here after all S/R conflicts
3680 in the state have been fully examined.
3681 * src/print.c (shift_set): Rename to...
3682 (no_reduce_set): ... this.
3683 (print_reductions): Update for rename, and add %nonassoc error action
3684 tokens to no_reduce_set so that, when printing the first remaining
3685 reduction on an error action token, the reduction is enclosed in
3687 (print_results): Update for rename.
3688 * tests/conflicts.at (Solved conflicts report for multiple reductions
3689 in a state): New test case.
3690 (%nonassoc error actions for multiple reductions in a state): New test
3693 * src/main.c (main): Don't depend on C99 features.
3695 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
3697 * build-aux/.cvsignore: Add compile.
3698 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
3701 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
3703 * bootstrap (slurp): Create target directories that don't exist.
3704 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
3706 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
3708 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
3710 * closure.c (closure): Likewise.
3711 * state.h (reductions): Comment sorting of rules.
3712 (state): Comment sorting of items.
3714 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
3716 Fix C++ test cases after recent Gnulib changes. Discussed starting at
3717 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
3718 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
3719 definition in order to avoid Gnulib headers since we don't use config.h
3721 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
3722 rather than AT_DATA so that config.h is included.
3724 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
3726 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
3727 instead of fprintf. Guard these functions with #if YYDEBUG instead of
3728 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
3729 and so that YYFPRINTF is guaranteed to be defined here.
3731 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
3733 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
3735 (muscle_percent_define_check_values): ... this more helpful function.
3736 Again, it's not used yet, but it will be.
3737 * src/muscle_tab.h: Likewise.
3739 Improve some comments in parser table construction.
3740 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
3741 (generate_states): Don't mention ruleset, which is internal to closure.
3742 * src/closure.c (closure): Explain sorting of core and itemset, which
3743 is required for this function to behave correctly.
3744 * src/closure.h (closure): Mention sorting.
3746 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
3748 * src/lalr.c (state_lookahead_tokens_count): For code readability,
3749 move the check for disabled transitions to an aver since conflict
3750 resolution hasn't happened yet.
3752 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3753 labels a state as inconsistent just because it has error transitions.
3754 The original form of this check appeared in revision 1.1 of lalr.c,
3755 which was committed on 1991-12-21. Now (at least), changing the
3756 consistency label on such a state appears to have no useful effect in
3757 any of the places it is examined, which I enumerate below. The key
3758 point to understanding each item in this enumeration is that a state
3759 with an error transition is labelled consistent in the first place only
3760 if it has no rules, so the check cannot matter for states that have
3761 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3762 to try to identify its conflicts, and a state must have *rules* to have
3763 conflicts. (2) Labelling a state as inconsistent will affect how
3764 action_row sets the default *rule* for the state. (3) Labelling a
3765 state as inconsistent will cause build_relations to add lookback edges
3766 to *rules* in that state.
3767 * src/state.h (struct state): Word the comment for member consistent
3770 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
3772 Don't depend on C99 features.
3773 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
3774 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
3775 * src/reader.c (check_and_convert_grammar): Fix for-loop.
3776 * src/state.c (state_mark_reachable_states): Fix for-loop.
3777 (state_remove_unreachable_states): Fix for-loop.
3779 Don't widen struct state with member reachable just to temporarily
3780 record reachability. Instead, use a local bitset.
3781 * src/state.h (struct state): Remove member.
3782 * src/state.c (state_new): Don't initialize it.
3783 (state_mark_reachable_states): Rename to...
3784 (state_record_reachable_states): ... this, and use bitset.
3785 (state_remove_unreachable_states): Use bitset.
3787 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
3789 * src/Makefile.am (yacc): Quote target action commands properly so
3790 that the yacc script isn't corrupt. Reported by Hans Aberg at
3791 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
3793 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
3794 the case of pure parsers. Reported by Frans Englich at
3795 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
3796 * THANKS: Add Frans Englich.
3798 * NEWS (2.3a+): In the %code entry, reference section `Bison
3799 Declaration Summary' from the manual now since the %code summary has
3801 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
3802 in the rules section must be terminated by semicolons.
3804 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
3806 Extend the front-end API for %define variables to more completely
3807 mirror the back-end. This will be useful in the future.
3808 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
3809 Update comments to mention the new front-end counterparts of these
3811 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code

3821 * src/muscle_tab.h (muscle_percent_define_get,
3822 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
3825 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
3827 * NEWS (2.3a+): Mention yesterday's state-removal change.
3828 (2.3a): Remove the %language entry, which was added after 2.3a.
3829 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
3830 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
3831 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
3832 tests/existing.at: Update copyright date.
3834 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
3836 If conflict resolution makes states unreachable, remove those states,
3837 report rules that are then unused, and don't report conflicts in those

3860 (new_itemsets, save_reductions): Update for rename to nitemset.
3861 * src/closure.c (nritemset): Rename to...
3862 (nitemset): ... this since the "r" appears to meaningless and isn't
3863 used in the comments.
3864 (closure): Update for rename.
3865 * src/closure.h (nritemset): Update extern to...
3866 (nitemset): ... this.

3963 muscle_percent_define_default): New functions mimicking
3964 b4_percent_define_flag_if and b4_percent_define_default.
3966 For %define variables, report locations for invalid values and

3991 * src/print.c (lookahead_set, state_default_rule): Remove.
3992 (print_reductions): Replace state_default_rule invocation with
3993 equivalent use of yydefact, which was computed in token_actions in
3995 (print_results): Don't allocate lookahead_set.
3997 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
3999 * data/lalr1.java: Prefix all private members with yy.
4001 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
4003 Use YYFPRINTF instead of fprintf where appropriate. Reported by
4004 Sebastien Fricker at
4005 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
4006 * THANKS: Add Sebastien Fricker.

4021 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
4023 Undo my 2007-02-07 change, switching back to the c-strcase module
4024 introduced in the 2007-02-03 change. Bruno Haible reported that
4025 the 2007-02-07 change would be dangerous in Turkish if we add a
4026 language whose name contains "i", since "i" is not lowercase "I"
4028 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
4029 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,

4036 2007-02-11 Bruno Haible <bruno@clisp.org>
4038 Enable the Java related testsuite tests when the only Java compiler
4039 found is a gcj < 4.3. Discussed at
4040 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
4041 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
4043 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
4045 * data/Makefile.am: Update copyright date.
4046 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
4047 yypstate_new returns NULL.
4048 (yypstate_new): Return NULL if malloc does.
4049 * src/reader.c (packgram): Move translation of rule actions from the
4050 beginning of packgram to...
4051 (check_and_convert_grammar): ... here right before packgram is invoked
4052 so it's easier to write more complete comments, and remove redundant
4055 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
4057 As in semantic actions, make @$ in %initial-action, %destructor, and
4058 %printer imply %locations.
4059 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
4061 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
4062 (@$ in %initial-action implies %locations,
4063 @$ in %destructor implies %locations,
4064 @$ in %printer implies %locations): ... these new test cases.
4066 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
4068 Undo most of the 2007-02-03 change, switching to the strcase module
4069 now that gnulib strcase has been fixed.
4070 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
4071 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
4072 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
4073 * m4/.cvsignore: Add strcase.m4.
4074 * src/getargs.c: Revert 2007-02-03 change, as follows.
4075 Don't include c-strcase.h.
4076 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
4077 strcasecmp has "unspecified behavior" outside the POSIX locale,
4078 but it works fine in practice if at least one argument is ASCII,
4079 as is the case in Bison.
4081 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
4083 * tests/java.at: Skip tests if only one of javac/java is present.
4084 Reported by Joel E. Denny.
4085 * tests/atlocal.in: Adjust copyright years.
4087 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
4089 * data/lalr1.java (Stack): Work around old verifiers that disallow
4090 access to the private fields of an inner class, from the outer class.
4091 We can make Stack's fields public because user code doesn't have access
4092 to the instance of Stack used by parse(). Reported by Paul Eggert.
4094 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
4096 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
4097 the right spot for these files?
4098 * bootstrap.conf (gnulib_modules): Add c-strcase.
4099 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
4101 * src/getargs.c: Include c-strcase.h.
4102 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
4103 to avoid unspecified behavior.
4105 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
4107 * doc/bison.texinfo (Decl Summary): Correct typo.
4109 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
4111 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
4112 Complain if the value does not match empty, "true" or "false".
4113 * data/c++.m4: Adjust default definitions of %define variables.
4114 * data/java.m4: Adjust default definitions of %define variables.
4115 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
4117 * tests/input.at (Boolean %define variables): Test new behavior.
4119 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
4121 * NEWS: Mention java.
4122 * TODO: Remove things that are done.
4123 * bootstrap.conf: Add javacomp-script and javaexec-script.
4124 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
4126 * data/Makefile.am: Add new files.
4127 * data/java-skel.m4: New.
4128 * data/java.m4: New.
4129 * data/lalr1.java: New.
4131 * doc/bison.texinfo: Put "A Complete C++ Example" under
4132 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
4133 under Other Languages.
4135 * src/getargs.c (valid_languages): Add Java.
4136 * src/getargs.h (struct bison_language): Update size of string fields.
4138 * tests/Makefile.am: Add java.at.
4139 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
4140 * tests/java.at: New.
4141 * tests/testsuite.at: Include it.
4143 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
4146 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
4147 at_directive_argv arguments so these no longer have to be global
4148 variables. Also, update the implementation for the following changes.
4149 (fail_for_at_directive_too_many_args,
4150 fail_for_at_directive_too_few_args): Add at_directive_name argument.
4151 (at_directive_name): Remove as at_directive_argv[0] will be used for
4153 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
4154 for the directive name.
4155 (at_directive_argc, at_directive_argv): Make these local within
4156 skel_lex instead of global.
4157 (INITIAL): Update directive start action for above changes.
4158 (SC_AT_DIRECTIVE_ARG): Rename to...
4159 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
4160 (SC_AT_DIRECTIVE_SKIP_WS): Update.
4161 (scan_skel): Move yylex_destroy to...
4162 (skel_scanner_free): ... here.
4163 * tests/skeletons.at (installed skeleton file name): Rename to...
4164 (installed skeleton file names): ... this.
4166 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
4168 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4169 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
4170 Summary" not "Directives".
4171 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
4172 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
4173 since the former is now the more complete one.
4174 (Prologue Alternatives): Likewise and do the same for %defines.
4175 (Table of Symbols): Add summary of %code, add summary of %define, and
4176 move full %code documentation to...
4177 (Decl Summary): ... here for consistency with other entries in these
4179 Move %define entry in order to keep this list alphabetized.
4180 Reword %define entry a little to put less emphasis on the skeleton
4181 concept, which most users shouldn't have to think about.
4183 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
4185 Adjust to recent gnulib changes.
4186 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
4187 Add string.h, string_.h, unistd_.h, wchar_.h.
4188 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
4189 * src/system.h: Don't include <stpcpy.h>; this is now done by
4192 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
4194 Simplify implementation of unqualified %code, implement macros for
4195 uniform treatment of boolean %define flags. Document %define.
4196 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
4197 b4_percent_code_ifdef): New.
4198 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
4199 * data/c++.m4: Define default value for global_tokens_and_yystype.
4200 * data/glr.cc: Likewise.
4201 * data/location.cc: Use b4_percent_define_flag_if.
4203 * doc/bison.texinfo (Decl Summary): Document %define.
4205 * src/parse-gram.y (Unqualified %code): Change muscle name to
4207 (content.opt): Default to empty.
4209 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
4211 Implement support for relative and absolute skeleton file names.
4212 Discussed starting at
4213 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
4214 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
4215 (Bison Options): Document in --skeleton entry.
4216 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
4217 full_skeleton can't necessarily hold all of pkgdatadir.
4218 If the specified skeleton file name contains a `/', don't prepend
4220 * src/parse-gram.y (prologue_declaration): If the specified skeleton
4221 file name contains a `/', prepend the grammar file directory.
4222 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
4223 * skeletons.at: New file.
4224 (relative skeleton file names): New test case.
4225 (installed skeleton file names): New test case.
4226 * tests/testsuite.at: Include skeletons.at.
4228 * bootstrap: Update copyright to 2007.
4230 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
4232 * bootstrap: Remove occurrences of .#bootmp from the files.
4234 2007-01-17 Akim Demaille <akim@epita.fr>
4236 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
4238 Use per-type %printer.
4240 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
4242 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

4250 2007-01-16 Akim Demaille <akim@epita.fr>
4252 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
4254 (Calc++ Scanner): Exit with failure if we can't open the input
4256 Accept "-" standing for stdin.
4257 (Calc++ Top Level): Print the result only if the parsing was
4260 2007-01-16 Akim Demaille <akim@epita.fr>
4262 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
4264 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
4265 and Joel E. Denny <jdenny@ces.clemson.edu>
4267 Clean up %define and %code implementation in M4 some. Most
4268 importantly, rename all related macros to be in the b4_percent_define
4269 and b4_percent_code namespaces. Also, complete support for `.' in
4270 %define variable names and %code qualifiers.
4271 * data/bison.m4 (b4_check_user_names): Check for special
4272 "SKELETON-NAMESPACE(name)" macros instead of using two nested
4274 (b4_get_percent_define, b4_get_percent_code): Rename to...
4275 (b4_percent_define_get, b4_percent_code_get): ... these.
4276 Extend documentation with examples.
4277 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
4278 b4_percent_define_skeleton_variables and
4279 b4_percent_code_skeleton_qualifiers.
4280 Expect any value for the %define variable `foo' to be stored in the
4281 macro named `b4_percent_define(foo)'; expect any %code blocks for the
4282 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
4283 expect any unqualified %code blocks to be stored in a macro named
4284 `b4_percent_code_unqualified'.
4285 Use m4_indir so that %define variable names and %code qualifiers can
4286 contain `.', which is allowed by the grammar parser.
4287 (b4_percent_define_default): New macro to set a default value for a
4289 (m4_wrap): Update wrapped code, and fix some underquoting.
4290 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
4291 Expect grammar uses of %define variables and %code qualifiers to be
4292 defined in b4_percent_define_user_variables and
4293 b4_percent_code_user_qualifiers.
4294 * data/c++.m4: Use b4_percent_define_default rather than
4295 m4_define_default. Fix some underquoting. Skeleton usage of %define
4296 variable define_location_comparison now implies skeleton usage of
4297 %define variable filename_type.
4298 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4299 data/push.c, data/yacc.c: Update macro names.
4300 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
4303 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
4305 DJGPP specific issues.
4307 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
4308 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
4310 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4312 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
4313 run parsers in all tests so that Valgrind is invoked during
4314 maintainer-check-valgrind.
4315 (Duplicate representation of merged trees): Free all semantic values.
4316 (Duplicated user destructor for lookahead): Likewise.
4318 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4320 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
4321 command-line prefix.
4322 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
4323 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
4324 miss Valgrind messages.
4325 (Exploding the Stack Size with Malloc): Likewise.
4327 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4329 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
4330 locals. Reported by Juan Manuel Guerrero at
4331 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
4332 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
4333 Fix some indentation also.
4334 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
4335 explaining this issue.
4337 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
4338 and Joel E. Denny <jdenny@ces.clemson.edu>
4340 Simplify union and prologue handling, and escape union and lex/parse
4341 params with digraphs.
4342 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
4343 values to the empty string since these are no longer guaranteed
4344 initialized by the front-end.
4345 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
4346 braces around b4_user_stype since this is no longer done by the
4348 * src/files.c, src/files.h (pre_prologue_obstack,
4349 post_prologue_obstack): Remove.
4350 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
4351 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
4352 with digraphs. This fixes lex params and parse params.
4353 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
4354 * src/output.c (prepare): Remove muscle insertion of the prologues.
4355 (output): Remove freeing of pre_prologue_obstack and
4356 post_prologue_obstack.
4357 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
4358 than prologue_augment for prologue parsing so you don't need prologue
4360 (grammar_declaration): For %union RHS, use `braceless' instead of
4361 "{...}" so that braces are already stripped and code is escaped with
4363 * src/reader.c (prologue_augment): Remove.
4364 (reader): Remove initialization of pre_prologue_obstack and
4365 post_prologue_obstack.
4366 * src/reader.h (prologue_augment): Remove.
4368 * data/c.m4: Remove stray parenthesis.
4370 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4372 Remove quotes from variables names in %define directives and from
4373 qualifiers in %code directives, and restrict the characters that are
4374 allowed in them to M4-friendly ones. For %define, continue to support
4375 the quoted form as a deprecated feature. Discussed starting at
4376 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
4377 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
4379 * doc/bison.texinfo (Prologue Alternatives): Update.
4380 (Decl Summary): In %defines entry, update mention of `%code requires'
4381 and `%code provides'.
4382 (C++ Location Values): Update %define uses.
4383 (Calc++ Parser Interface): Likewise.
4384 (Calc++ Parser): Likewise, and update `%code requires' uses.
4385 (Table of Symbols): Update %code documentation.
4386 * src/parse-gram.y (prologue_declaration): For %define variables, use
4387 `variable' instead of `STRING'.
4388 (grammar_declaration): For %code qualifiers, use `ID' instead of
4390 (variable): New nonterminal that takes an `ID' or a `STRING'.
4391 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
4393 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
4394 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
4395 (%define errors): Update %define uses.
4397 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4399 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
4400 instead of muscle_insert for %define values so that M4-special
4401 characters are replaced with digraphs.
4402 * tests/input.at (%define errors): Extend to check weird values.
4404 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4406 Instead of having skeletons declare all valid %define variables and
4407 %code qualifiers, provide macros that retrieve the associated values
4408 and build these lists automatically. Thus Bison will now warn when a
4409 variable or qualifier is not used by the skeleton in the current
4410 invocation regardless of whether it might sometimes be used by that
4411 skeleton in other invocations. Also, move all %define value macros to
4412 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
4413 form, which is replaced by %code.
4414 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
4415 (b4_check_user_names): ... this, and change the series of valid name
4416 arguments to a single list argument for names used in the skeleton
4417 similar to the existing list argument for names used in the grammar.
4418 Warn instead of complaining.
4419 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
4420 values and %code code, to format %code code properly, and to build
4421 lists of all %define variables and %code qualifiers used in the
4422 skeleton: b4_skeleton_percent_define_variables and
4423 b4_skeleton_percent_code_qualifiers.
4424 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
4426 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
4427 the skeleton names lists can finish building first. In place of
4428 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
4429 expect the lists b4_user_percent_define_variables and
4430 b4_user_percent_code_qualifiers.
4431 * data/c++.m4: Where setting default values for b4_parser_class_name,
4432 b4_location_type, b4_filename_type, b4_namespace, and
4433 b4_define_location_comparison, update their names to the
4434 b4_percent_define_ namespace.
4435 * data/glr.c: Don't use b4_check_percent_define_variables and
4436 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4437 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
4438 (b4_parser_class_name, b4_namespace): Define these using
4439 b4_get_percent_define for parser_class_name and namespace.
4440 * data/location.cc: Use b4_get_percent_define.
4441 * data/push.c: Don't use b4_check_percent_define_variables and
4442 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4443 * data/yacc.c: Likewise, and don't call m4_exit in
4444 b4_use_push_for_pull_if or m4_wrap code will never execute.
4445 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
4447 (muscle_grow_user_name_list): ... this for consistency with the
4448 terminology used in bison.m4.
4449 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
4450 %define variable names, and rename muscle used_percent_define_variables
4451 to user_percent_define_variables.
4452 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
4453 user_percent_code_qualifiers.
4455 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
4456 {CODE} form is no longer accepted.
4457 * tests/input.at (Reject bad %code qualifiers): Rename to...
4458 (Reject unused %code qualifiers): ... this, and update test output.
4459 (%define error): Update test output.
4461 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
4463 Check for unrecognized %define variables similar to checking for
4464 unrecognized %code qualifiers. Check for redefined %define variables.
4465 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
4467 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
4468 (b4_check_percent_define_variables): New, also wraps it.
4469 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
4470 variables using b4_check_percent_define_variables.
4471 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
4472 all those exercised in the test suite and all those listed in the
4473 `Default values' section of c++.m4. Are there others?
4474 * data/push.c, data/yacc.c: Declare no valid %define variables.
4475 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
4476 similar to muscle_find, but it works even when the muscle stores a
4478 (muscle_grow_used_name_list): New function for constructing the used
4479 name list muscles that b4_check_for_unrecognized_names requires.
4480 * src/parse-gram.y (prologue_declaration): Warn if a variable is
4481 %define'd more than once. Define the b4_used_percent_define_variables
4482 muscle with muscle_grow_used_name_list.
4483 (grammar_declaration): Abbreviate %code code with
4484 muscle_grow_used_name_list.
4485 * tests/input.at (%define errors): New.
4487 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4489 Provide warn_at, complain_at, and fatal_at function callbacks to the
4490 skeletons, and use this for %code qualifier complaints.
4491 * data/bison.m4 (b4_error_at): New, invoked by...
4492 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
4493 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
4494 @fatal_at(...@) directives.
4495 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
4496 qualifiers in b4_used_percent_code_qualifiers and to use
4498 * src/location.c, src/location.h (boundary_set_from_string): New global
4500 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
4502 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
4503 to b4_used_percent_code_qualifiers.
4504 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
4506 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
4507 (lineno): Rename to...
4508 (out_lineno): ... this so I don't misunderstand it again.
4509 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
4510 here; these newlines are in the input but not the output file.
4511 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
4512 (at_directive_perform): ... this new static function, and add handling
4513 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
4515 * tests/input.at (Reject bad %code qualifiers): Update test output with
4516 locations and extend.
4518 * tests/output.at (Output file name: [, Output file name: ]): Remove
4519 bogus comment about these tests failing.
4521 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4523 Clean up b4_check_percent_code_qualifiers a little.
4524 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
4525 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
4526 documentation and add examples.
4527 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
4530 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
4532 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
4533 unreliable -- especially when they're hidden inside another macro.
4534 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
4535 data/c.m4: Remove m4_divert(-1).
4536 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4537 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
4538 m4_divert_push(0) and m4_divert_pop(0).
4539 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
4540 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
4541 pushed and popped by m4sugar, should be first on the stack.
4543 Provide warn, complain, and fatal function callbacks to the skeletons.
4544 This provides more flexibility than m4_fatal, improves the error
4545 message format, and captures messages for translation. Discussed
4547 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
4548 * data/bison.m4 (b4_error): New, invoked by...
4549 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
4550 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
4551 directives. Because these M4 macros might be called when the current
4552 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
4553 the previous removal of uses of m4_divert, which caused trouble.
4554 (b4_check_percent_code_qualifiers): Use b4_complain instead of
4555 m4_fatal to report unrecognized %code qualifiers.
4556 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
4557 push parser requests.
4558 * data/glr.c: Use b4_complain instead of m4_fatal to report
4559 non-deterministic push parser requests.
4560 Update @output usage to @output(...@) form.
4561 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
4562 report missing %defines. Update @output usage to @output(...@) form.
4563 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
4565 * src/main.c (main): Invoke skel_scanner_free.
4566 * src/scan-skel.h (skel_scanner_free): Prototype new function.
4567 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
4568 obstack_for_string from flex-scanner.h.
4569 (YY_DECL): Use to declare skel_lex static.
4570 (decode_at_digraphs): Remove; now handled in the new
4571 SC_AT_DIRECTIVE_ARG start condition.
4572 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
4574 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
4575 at_directive_argv): New static globals.
4576 (INITIAL): Use fail_for_invalid_at.
4577 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
4578 recognize the start of a generalized `@directive(...@)' form and
4580 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
4581 directive args (using the new obstack_for_string), to decode the
4582 contained @ diagraphs, and to perform the directive. It recognizes
4583 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
4585 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
4586 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
4588 (scan_skel): Initialize obstack_for_string on the first call.
4589 (skel_scanner_free): New function to free obstack_for_string.
4590 * tests/input.at (Reject bad %code qualifiers): Update test output.
4592 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
4594 Consolidate the 4 prologue alternative directives (%code, %requires,
4595 %provides, and %code-top) into a single %code directive with an
4596 optional qualifier field. Discussed at
4597 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
4598 * NEWS (2.3a+): Rewrite the existing entry for the prologue
4600 * doc/bison.texinfo (Prologue Alternatives): Update.
4601 (Decl Summary): Update to %code "requires" and %code "provides".
4602 (Calc++ Parser): Update to %code "requires".
4603 (Table of Symbols): Remove entries for %requires, %provides, and
4604 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
4605 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
4606 are replaced by b4_percent_code_provides and b4_percent_code_requires,
4607 which are skeleton-specific.
4608 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
4609 declare what %code qualifiers it supports and to complain if any other
4610 qualifiers were used in the grammar.
4611 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
4612 and b4_user_code([b4_percent_code_provides]) in place of
4613 b4_user_requires and b4_user_provides.
4614 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
4615 Add b4_user_code([b4_percent_code_top]) and
4616 b4_user_code([b4_percent_code]).
4617 Invoke b4_check_percent_code_qualifiers.
4618 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4619 PERCENT_REQUIRES): Remove.
4620 (grammar_declaration): Remove RHS's for %code-top, %provides, and
4621 %requires. Rewrite the %code RHS as the unqualified form defining the
4622 muscle b4_percent_code. Add another RHS for the qualified %code form,
4623 which defines muscles of the form b4_percent_code_QUALIFIER and the
4624 b4_used_percent_code_qualifiers muscle.
4625 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4626 PERCENT_REQUIRES): Remove.
4627 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
4628 %code "requires" and %code "provides".
4629 * tests/input.at (Reject bad %code qualifiers): New.
4631 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4633 Use the new code_props interface for destructors and printers.
4634 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
4635 printer_location members, and change the type of the destructor and
4636 printer members to code_props.
4637 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
4638 symbol_printer_get, semantic_type_destructor_set,
4639 semantic_type_printer_set, default_tagged_destructor_set,
4640 default_tagless_destructor_set, default_tagged_printer_set,
4641 default_tagless_printer_set): Use code_props in arguments and return
4642 types in place of char const * and location.
4643 (symbol_destructor_location_get, symbol_printer_location_get): Remove
4644 since the locations are now contained in the return of
4645 symbol_destructor_get and symbol_printer_get.
4646 * src/output.c (symbol_destructors_output, symbol_printers_output):
4648 (symbol_code_props_output): ... this to eliminate duplicate code.
4649 (output_skeleton): Update to use symbol_code_props_output.
4650 * src/reader.c (symbol_should_be_used): Update use of
4651 symbol_destructor_get.
4652 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4653 Update uses of the various _destructor_set and _printer_set functions.
4654 * src/symtab.c: (default_tagged_destructor_location,
4655 default_tagless_destructor_location, default_tagged_printer_location,
4656 default_tagless_printer_location): Remove since we...
4657 (default_tagged_destructor, default_tagless_destructor,
4658 default_tagged_printer, default_tagless_printer): ... change the type
4659 of these to code_props.
4660 (symbol_new, semantic_type_new, symbol_destructor_set,
4661 semantic_type_destructor_set, symbol_destructor_get,
4662 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
4663 symbol_check_alias_consistency, default_tagged_destructor_set,
4664 default_tagless_destructor_set, default_tagged_printer_set,
4665 default_tagless_printer_set): Update.
4666 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
4667 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
4669 (symbol_print): Use SYMBOL_CODE_PRINT.
4671 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4673 Use the new code_props interface for rule actions.
4674 * src/symlist.h (symbol_list): Replace action, action_location, and
4675 used members with a code_props action_props member.
4676 * src/reader.c (symbol_should_be_used, grammar_rule_check,
4677 grammar_midrule_action, grammar_current_rule_merge_set,
4678 grammar_current_rule_symbol_append, packgram): Update.
4679 * src/scan-code.h (translate_rule_action): Remove, no longer used.
4680 * src/scan-code.l (handle_action_dollar): Update.
4681 (translate_rule_action): Remove, no longer used.
4682 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
4684 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4686 Use the new code_props interface in parse-gram.y.
4687 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
4688 Update all uses of translate_* functions to use the new code_props
4689 interface and to use gram_scanner_last_string_free and
4690 code_scanner_last_string_free where possible.
4691 (grammar_declaration): symbol_list_destructor_set and
4692 symbol_list_printer_set now perform the translation, so don't do it
4693 here. Use gram_scanner_last_string_free where possible.
4694 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
4695 translate_code): Remove, no longer used.
4696 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
4697 symbol_list_printer_set): Perform code translation here rather than
4698 depending on the caller to do so.
4700 * src/symlist.h (struct symbol_list): Correct some documentation typos.
4701 * src/scan-gram.h (gram_last_string): Remove declaration.
4702 * src/scan-gram.l (last_string): Declare it static.
4704 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4706 Encapsulate code properties and related functionality for the various
4707 destructors, printers, and actions into a code_props structure and
4708 interface. This patch merely implements code_props in scan-code.h and
4709 scan-code.l. Future patches will rewrite other modules to use it.
4710 Discussed starting at
4711 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
4712 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
4713 consistently initialize const structs that have an empty location
4715 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
4716 to ensure consistency.
4717 * src/scan-code.h (code_props): New structure.
4718 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
4719 function, macro, and const global variable for initializing a
4720 code_props with no code.
4721 (code_props_plain_init, code_props_symbol_action_init,
4722 code_props_rule_action_init, code_props_translate_code): The rest of
4723 the new code_props functional interface. Among other things, the init
4724 functions set the code_props kind field so that
4725 code_props_translate_code will know whether to behave like
4726 translate_symbol_action, translate_rule_action, or translate_code.
4727 These old translate functions must remain until all other modules are
4728 updated to use the new code_props interface.
4729 (code_scanner_last_string_free): New function similar to
4730 gram_scanner_last_string_free.
4731 (code_scanner_free): Add documentation.
4732 * src/scan-code.l: Implement the new interface.
4733 (code_lex): Make it static, add a code_props* argument, and remove the
4735 (last_string): New static global similar to the one in scan-gram.l.
4736 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
4738 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
4739 code_props since Bison may one day use this information for destructors
4741 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
4742 (handle_action_dollar): Use symbol_list_n_get and set used flag
4743 directly since symbol_list_n_used_set is removed.
4744 (translate_action): Add a code_props* argument and remove the rule,
4745 action, and location arguments. Pass the code_props* on to code_lex.
4746 (translate_rule_action, translate_symbol_action, translate_code):
4747 Rewrite as wrappers around the new code_props interface.
4748 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
4749 it would eventually need to break the encapsulation of code_props.
4751 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4753 * etc/.cvsignore: New.
4755 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4757 Add maintainer-push-check to run maintainer-check using push parsing in
4758 place of pull parsing where available.
4759 * Makefile.am (maintainer-push-check): New.
4760 * data/bison.m4 (b4_use_push_for_pull_if): New.
4761 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
4762 appropriately based on their existing values.
4763 (yypush_parse): Don't print push-parser-specific diagnostics if push
4764 parsing is being used in place of pull parsing.
4765 * data/yacc.c: If push parsing should replace pull parsing, redirect to
4767 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
4768 variable, and insert b4_use_push_for_pull_flag into muscles.
4769 * tests/Makefile.am (maintainer-push-check): New.
4771 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4773 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
4774 (whether successful or failed) so that yypush_parse can be invoked
4775 again to start a new parse using the same yypstate.
4776 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
4777 check multiple yypull_parse invocations on the same yypstate. For pull
4778 mode, extend to check multiple yyparse invocations.
4779 (Exploding the Stack Size with Alloca): Extend to try with
4781 (Exploding the Stack Size with Malloc): Likewise.
4783 * tests/calc.at (Simple LALR Calculator): Don't specify
4784 %skeleton "push.c" since %push-pull-parser implies that now.
4785 * tests/headers.at (export YYLTYPE): Don't check for the push
4786 declarations. Otherwise, this test case can't be used to see if push
4787 mode can truly emulate pull mode.
4788 * tests/input.at (Torturing the Scanner): Likewise.
4789 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
4790 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
4791 AT_YACC_IF, which now includes the case of push mode since %skeleton
4792 need not be used for push mode. This will be more intuitive once
4793 push.c is renamed to yacc.c.
4795 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4797 For push mode, convert yyparse from a macro to a function, invoke yylex
4798 instead of passing a yylexp argument to yypull_parse, and don't
4799 generate yypull_parse or yyparse unless %push-pull-parser is declared.
4800 Discussed starting at
4801 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
4802 * data/bison.m4 (b4_pull_if): New.
4803 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
4804 * data/push.c: Improve M4 quoting a little.
4805 (b4_generate_macro_args, b4_parenthesize): Remove.
4806 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
4807 any time a pull parser is requested.
4808 Don't #define this as a wrapper around yypull_parse. Instead, when
4809 both push and pull are requested, make it a function that does that
4811 (yypull_parse): If there's a b4_prefix, #define this to
4812 b4_prefix[pull_parse] when both push and pull are requested.
4813 Don't define this as a function unless both push and pull are
4815 Remove the yylexp argument and hard-code yylex invocation instead.
4816 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
4818 * src/getargs.c (pull_parser): New global initialized to true.
4819 * getargs.h (pull_parser): extern it.
4820 * src/output.c (prepare): Insert pull_flag muscle.
4821 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
4822 (prologue_declaration): Set both push_parser and pull_parser = true for
4823 %push-pull-parser. Set push_parser = true and pull_parser = false for
4825 * src/scan-gram.l: Don't accept %push_parser as an alternative to
4826 %push-parser since there's no backward-compatibility concern here.
4827 Scan %push-pull-parser.
4828 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
4829 instead of %push-parser.
4830 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
4831 prototype it in the module that calls yyparse.
4832 * tests/input.at (Torturing the Scanner): Likewise.
4833 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
4835 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
4837 Update etc/bench.pl. Optimize push mode a little (the yyn change
4838 deserves most of the credit).
4839 * Makefile.am (SUBDIRS): Add etc subdirectory.
4840 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
4841 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
4842 yytoken, yyval, and yyloc declarations to...
4843 (yyparse or yypush_parse): ... here to improve performance. For
4844 yypush_parse invocations after the first, be sure to assign yyn its old
4846 (yypstate_new): Don't bother initializing the yyresult field since the
4847 initial value isn't used.
4848 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
4849 remove the #define that, in push mode, set it to yyps->NAME.
4850 * etc/Makefile.am: New.
4851 * etc/bench.pl: Remove and build it instead from...
4852 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
4853 "tests/bison" from the build directory by default rather than just
4854 invoking "bison" from $PATH.
4855 (calc_grammar): Update push parser code: don't declare yylval globally,
4856 don't define yyparse_wrapper, and don't #define yyparse.
4857 (bench_grammar): Update to check all working combinations of yacc.c,
4858 push.c, impure, pure, pull, and push.
4860 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4862 For push mode, add pull wrappers around yypush_parse.
4863 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
4864 (yypull_parse): New function wrapping yypush_parse.
4865 (yyparse): New #define wrapping yypull_parse.
4866 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
4868 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
4869 prototype yylex in the module that calls yyparse, and don't prototype
4870 yyparse there. Otherwise, the yyparse expansion won't compile.
4871 * tests/input.at (Torturing the Scanner): Likewise.
4873 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4875 Enable push parsers to operate in impure mode. Thus, %push-parser no
4876 longer implies %pure-parser. The point of this change is to move
4877 towards being able to test the push parser code by running the entire
4878 test suite as if %push-parser had been declared.
4879 * data/push.c (yypush_parse): For impure mode, remove the
4880 yypushed_char, yypushed_val, and yypushed_loc arguments.
4881 Instead, declare these as local variables initialized to the global
4882 yychar, yylval, and yylloc.
4883 For the first yypush_parse invocation only, restore the initial values
4884 of these global variables when it's time to read a token since they
4885 have been overwritten.
4886 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
4888 * tests/calc.at (Simple LALR(1) Calculator): Always declare
4889 %pure-parser along with %push-parser since this test case was designed
4890 for pure push parsers.
4891 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
4892 (AT_YACC_OR_PUSH_IF): New.
4893 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
4894 add a note that it's still wrong for some cases (as it has been for a
4896 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
4897 %push-parser no longer implies %pure-parser.
4899 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4901 Remove some unnecessary differences between the pull parser code and
4902 the push parser code. This patch enables yynerrs in push mode.
4903 * data/push.c: Reformat M4 a little.
4904 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
4905 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
4906 because push mode is on. Instead, if pure mode is on, move yynerrs
4908 (b4_declare_parser_state_variables): ... here.
4909 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
4910 to yyps->NAME so it can be used in yypush_parse.
4911 (yypush_parse): Don't omit uses of yynerrs in push mode.
4913 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4915 Fix bug such that the first pushed token's value and location are
4916 sometimes overwritten (sometimes by %initial-action) before being used.
4917 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
4918 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
4919 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
4920 more closely mimic the pull parser logic.
4921 Don't copy the pushed token to yychar, yylval, and yylloc until it's
4922 time to read a token, which is after any initialization of yylval and
4924 (gottoken): Rename label to...
4925 (yyread_pushed_token): ... for clarity and to avoid infringing on the
4928 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4930 Rearrange initialization of the parser state variables so that the
4931 skeleton doesn't have to have a copy for pull mode and another for push
4932 mode. This patch also fixes at least a bug such that yylloc was not
4933 initialized (with b4_location_initial_line and
4934 b4_location_initial_column) upon calling yypush_parse. However, that
4935 initialization now overwrites the first token's location;
4936 %initial-action assigning @$ already did the same thing, and both bugs
4937 will be fixed in a later patch.
4938 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
4939 (b4_declare_parser_state_variables): Remove initialization of yytoken,
4940 yyss, yyvs, yyls, and yystacksize.
4941 (yypstate_new): Remove initialization of some yypstate fields: yystate,
4942 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
4944 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
4945 yyps->NAME so it can be used in yypush_parse.
4946 (yyparse or yypush_parse): For yypush_parse, don't print the
4947 "Starting parse" diagnostic for invocations after the first.
4948 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
4949 yypush_parse, only do it for the first invocation.
4950 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
4951 initialization to occur in yypush_parse but only on the first
4954 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4956 * data/push.c: Add CPP guards around push parser declarations in both
4957 the header and the code file.
4958 In the code file, move the push parser declarations to the same place
4959 they appear in the header file.
4960 Clean up the M4 some, especially the inconsistent underquoting in
4961 some b4_c_function_def and b4_c_function_decl uses.
4963 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4965 Encapsulate the push parser state variables into an M4 macro so the
4966 push skeleton doesn't have to list them again for pull mode's yyparse.
4967 For push mode, remove yypush_parse's local equivalents of these
4968 variables to eliminate unnecessary copying between the two sets at
4969 run-time. This patch also fixes at least a bug related to multiple
4970 %initial-action invocations in push mode.
4971 * data/push.c (b4_declare_parser_variables): Rename to...
4972 (b4_declare_scanner_communication_variables): ... this for clarity and
4974 (b4_declare_yyparse_variables): Remove and move its contents to the one
4975 spot where it was invoked.
4976 (b4_declare_parser_state_variables): New macro containing the parser
4977 state variables required by push mode.
4978 (struct yypstate): Replace all fields but yynew with
4979 b4_declare_parser_state_variables.
4980 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
4981 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
4982 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
4983 (yyparse or yypush_parse): For yyparse in pull mode, replace local
4984 parser state variable declarations with
4985 b4_declare_parser_state_variables.
4986 Don't initialize parser state variables when calling yypush_parse since
4987 yypstate_new already does that.
4988 Invoke the user's initial action only upon the first yypush_parse
4990 Remove all code that copies between the local parser state variables
4993 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4995 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
4996 prevent a name collision in a future patch where these names will
4997 sometimes be #define'd.
4998 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
4999 since it no longer has the same name as the existing argument.
5000 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
5002 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
5003 and Joel E. Denny <jdenny@ces.clemson.edu>
5005 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
5006 that the argument is case-insensitive, and there's no `=' here.
5007 For the %skeleton entry, mention that %language is better.
5008 (Bison Options): Likewise for --language and --skeleton. Move the
5009 --skeleton entry so that the `Tuning the parser' section is sorted
5010 alphabetically on long options.
5011 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
5012 %language directive in detail here; cross-reference the %language
5013 documentation instead.
5014 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
5015 `%require "2.3b"' so that the example is always up-to-date.
5016 (Table of Symbols): Add entries for %language and %skeleton.
5017 * examples/extexi (normalize): Instead of replacing every %require
5018 argument with the current Bison version, just substitute for
5019 `@value{VERSION}'. This guarantees that we're testing what actually
5020 appears in the documentation.
5021 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
5022 rather than `@VERSION@'.
5024 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5026 * NEWS: Reword the %language news a bit, and put it earlier.
5028 * src/getargs.c (skeleton_arg): Last arg is now location const *.
5029 Rewrite to simplify the logic.
5030 (language_argmatch): Likewise.
5031 (program_name): We now own this var.
5032 * src/getargs.h (struct bison_language): Use char[] rather than
5035 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
5037 * src/complain.c (program_name): Remove decl; no longer needed.
5038 * src/main.c (program_name): Remove; now belongs to getargs.
5040 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
5042 * NEWS: Document %language.
5044 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
5046 * data/c-skel.m4, data/c++-skel.m4: New files.
5047 * data/glr.c: Complain on push parsers.
5049 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
5051 (Decl Summary): Document %language and %skeleton.
5052 (Command line): Document -L.
5054 * examples/extexi: Rewrite %require directive.
5055 * examples/calc++/Makefile.am: Pass VERSION to extexi.
5057 * src/files.c (compute_exts_from_gc): Look in language structure
5059 (compute_file_name_parts): Check whether .tab should be added.
5060 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
5061 (language, skeleton_arg, language_argmatch): New.
5062 (long_options): Add --language.
5063 (getargs): Use skeleton_arg, add -L/--language.
5064 * src/getargs.h: Include location.h.
5065 (struct bison_language, language, skeleton_arg, language_argmatch): New.
5066 * src/output.c (prepare): Pick default skeleton from struct language.
5067 Don't dispatch C skeletons here.
5068 * src/parse-gram.y (PERCENT_LANGUAGE): New.
5069 (prologue_declaration): Add "%language" rule, use skeleton_arg.
5070 * src/scan-gram.l ("%language"): New rule.
5072 * tests/calc.at: Test %skeleton and %language.
5073 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
5074 (AT_GLR_IF): Look for %skeleton "glr.cc".
5075 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
5076 (AT_YACC_IF): Reject %language.
5078 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5080 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
5081 since it wasn't used; only the typedef name 'semantic_type' is needed.
5082 Also, omit trailing white space.
5084 * bootstrap: Sync from coreutils.
5085 (gnulib_extra_files): Add build-aux/announce.gen.
5086 (slurp): Adjust .gitignore files like .cvsignore files.
5087 * build-aux/announce-gen: Remove from CVS, since bootstrap
5090 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
5092 Make %push-parser imply %pure-parser. This fixes several bugs; see
5093 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
5094 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
5096 * data/push.c: Don't bother testing b4_push_if when deciding whether
5097 to expand b4_declare_parser_variables globally.
5098 (yypush_parse): Likewise in here.
5100 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
5101 (yy_reduce_print): Reformat M4 for readability.
5103 2006-12-15 Bob Rossi <bob@brasko.net>
5104 and Joel Denny <jdenny@ces.clemson.edu>
5106 * data/push.c (yypstate): Add typedef, and update all uses of
5107 struct yypstate to just yypstate.
5108 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
5110 2006-12-14 Bob Rossi <bob@brasko.net>
5112 * data/push.c (yypush_parse): Declare prototype regardless of
5115 2006-12-14 Bob Rossi <bob@brasko.net>
5117 * data/push.c (yyparse): Remove the prototype and the #define when in
5120 2006-12-13 Bob Rossi <bob@brasko.net>
5122 * data/push.c (yypstate_init): Rename to...
5123 (yypstate_new): ... this and use b4_c_function_def.
5124 (yypstate_delete): New.
5125 (yypush_parse): Change parameters yynval and yynlloc to be const.
5126 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
5127 yypstate_delete functions.
5129 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
5131 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
5132 strange test case titles. Reported by Bob Rossi.
5134 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
5136 * TODO: Add pointer to Sylvain Schmitz's work on static detection
5137 of potential ambiguities in GLR grammers.
5139 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
5141 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
5142 `bison ', use m4_index instead of m4_substr since chopping up a string
5143 containing M4-special characters causes problems here.
5145 Fix a couple of bugs related to special characters in user-specified
5146 file names, and make it easier for skeletons to compute output file
5147 names with the same file name prefix as Bison-computed output file
5149 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
5150 b4_parser_file_name and b4_spec_defines_file instead of
5151 @output_parser_name@ and @output_header_name@, which are now redundant.
5152 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
5153 b4_parser_file_name, b4_spec_defines_file, and the new
5154 @basename(FILENAME@) instead of @output_parser_name@ and
5155 @output_header_name@, which inappropriately escaped the file names as
5157 * src/files.c (all_but_ext): Remove static qualifier.
5158 (compute_output_file_names): Move `free (all_but_ext)' to...
5159 (output_file_names_free): ... here since all_but_ext is needed later.
5160 * src/files.h (all_but_ext): Extern.
5161 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
5162 exactly what MUSCLE_INSERT_STRING used to do.
5163 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
5164 characters are escaped properly.
5165 * src/output.c (prepare): Define muscle file_name_all_but_ext as
5167 For pkgdatadir muscle, maintain previous functionality by using
5168 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
5169 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
5170 digraphs would never be expanded. Hopefully no one has M4-special
5171 characters in his Bison installation path.
5172 * src/scan-skel.l: Don't parse @output_header_name@ and
5173 @output_parser_name@ anymore since they're now redundant.
5174 In @output, use decode_at_digraphs.
5175 Parse a new @basename command that invokes last_component.
5176 (decode_at_digraphs): New.
5177 (BASE_QPUTS): Remove unused.
5178 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
5179 (Output file name): New tests.
5181 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
5183 Warn about output files that are generated by the skeletons and that
5184 conflict with other output files.
5185 * data/glr.c: Don't generate the header file here when glr.cc does.
5186 * src/files.c (file_names, file_names_count): New static globals.
5187 (compute_output_file_names): Invoke output_file_name_check for files
5188 not generated by the skeletons and remove existing checks.
5189 (output_file_name_check): New function that warns about conflicting
5191 (output_file_names_free): Free file_names.
5192 * src/files.h (output_file_name_check): Declare.
5193 * src/scan-skel.l: Invoke output_file_name_check for files generated by
5195 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
5196 (Conflicting output files): New tests.
5198 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5200 * doc/bison.texinfo: Fix a couple of typos.
5202 2006-12-08 Bob Rossi <bob@brasko.net>
5204 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
5206 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
5208 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
5209 (yypush_parse): Rename yypvars argument to yyps and remove redundant
5211 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
5212 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
5214 2006-12-07 Bob Rossi <bob@brasko.net>
5215 and Joel Denny <jdenny@ces.clemson.edu>
5217 * data/push.c (yypvarsinit): Change return type from void* to struct
5218 yypvars*. No longer cast to void* on return.
5219 (struct yypvars): Remove yylen since it need not be remembered between
5220 yypushparse invocations.
5221 (yypushparse): Don't copy between yylen and pv->yylen.
5223 2006-12-05 Bob Rossi <bob@brasko.net>
5225 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
5226 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
5227 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
5228 (struct yypvars): Remove b4_declare_parser_variables.
5229 (yypvarsinit): Remove init code for removed variables.
5230 (global scope): Do not declare b4_declare_parser_variables if
5232 (yypushparse): Add b4_declare_parser_variables.
5233 Init new local variables, and remove init code for removed
5236 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
5237 and yyparse for other modes.
5238 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
5239 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
5240 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
5241 (AT_PURE_LEX_IF): True if pure or push parser.
5243 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>

5324 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
5325 later. Reported by Paul Eggert in

5342 --enable-gcc-warnings doesn't produce warnings that the return discards
5343 const. aver that the value and storage are the same since storage
5344 could potentially be NULL when value is not.
5345 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
5348 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
5350 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
5351 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
5352 us a slightly cleaner distribution, and also works.
5353 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
5356 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
5357 and Paul Eggert <eggert@cs.ucla.edu>
5359 Don't let Bison leak memory except when it complains.
5360 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
5361 (spec_defines_file, dir_prefix): Now char *, not const char *,
5362 since they are freed.
5363 * src/files.c: Likewise.
5364 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
5366 (tr): Now operates in-place. All uses changed.
5367 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
5369 (compute_file_name_parts, compute_output_file_names): Don't store
5370 read-only data in variables that will be freed.
5371 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
5372 src_extension, and header_extension.
5373 (output_file_names_free): New public function to free
5374 spec_verbose_file, spec_graph_file, spec_defines_file,
5375 parser_file_name, and dir_prefix.
5376 * src/getargs.c (getargs): Don't store read-only data in variables that
5378 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
5379 (which previously existed but was unused), and quotearg_free.
5380 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
5381 * src/muscle_tab.c: Likewise.
5382 (muscle_entry): Make the value char const *,
5383 and add a new storage member that is char * and can be freed.
5384 (muscle_entry_free): New private function.
5385 (muscle_init): Use it instead of free.
5386 (muscle_insert, muscle_grow): Update and use new storage member.
5387 (muscle_code_grow): Free the string passed to muscle_grow
5388 since it's not needed anymore.
5389 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
5390 add a new `char *code' member.
5391 ("{...}"): Declare semantic type as code.
5392 * src/scan-code.h (translate_rule_action):
5393 (translate_symbol_action, translate_code, translate_action): Return
5394 `char const *' rather than `char *' since external code should not free
5396 * src/scan-code.l: Likewise.
5397 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
5398 which is "{...}" in the parser.
5399 * tests/Makefile.am (maintainer-check-valgrind): Set
5400 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
5402 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
5404 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
5405 expecting a non-zero exit status sets --leak-check=summary and
5406 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
5407 this case, and we don't want to hear about it.
5409 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
5411 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
5412 instead of from the template, to simplify configuration a bit.
5413 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
5414 and m4/wint_t.m4, as they are needed with the latest gnulib.

5428 declarations): Run tests with and without --warnings=midrule-values.
5430 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
5431 than LIST_FREE directly.
5433 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

5452 empty subargument list. For example: `bison --warnings= parser.y'.
5454 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
5456 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
5457 the parser header file so that gcc doesn't warn.
5459 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>

5507 Don't apply the default %destructor/%printer to an unreferenced midrule
5509 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
5510 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
5511 like $@n instead of just @n so that the default %destructor/%printer
5512 logic doesn't see them as user-defined symbols.
5513 (symbol_is_dummy): Check for both forms of the name.
5514 * src/reader.c (packgram): Remove the `$' from each midrule symbol
5515 name for which the midrule value is referenced in any action.

5526 (packgram): Before invoking grammar_rule_check on any rule, make sure
5527 all actions have already been scanned in order to set `used' flags.
5528 Otherwise, checking that a midrule's $$ is set will not always work
5529 properly because the midrule check must forward-reference the midrule's

5543 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
5545 Similar to the recently removed %before-header, add %code-top as the
5546 alternative to the pre-prologue. Mentioned at

5652 Include <config.h> unconditionally.
5654 * bootstrap: Sync from coreutils, as follows:
5656 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
5658 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
5659 variable was sometimes used without being initialized. This
5660 messed up the installation of the INSTALL file in some cases.
5662 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
5664 * bootstrap (usage, main program, symlink_to_gnulib): Add option
5665 --copy. Inspired by a suggestion from Bruno Haible.
5667 2006-10-03 Jim Meyering <jim@meyering.net>
5669 * bootstrap: Undo last change to this file, since now gnulib-tool
5670 sticks with the automake default in generating dependencies.
5672 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
5674 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

5765 Fix problems with translating English-language diagnostics.
5766 * bootstrap: Fix bug introduced in recent bootstrap changes, with

5768 wasn't being captured.
5769 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
5770 * po/POTFILES.in: Add src/location.c, src/scan-code.l.

5777 2006-09-28 Jim Meyering <jim@meyering.net>
5779 Automatically generated dependencies are important even
5780 when all of the sources in a directory come from gnulib.
5781 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
5782 option that gnulib-tool adds to what becomes our lib/gnulib.mk.

5798 Adjust white space and comments to match GNU style better.
5800 2006-09-20 Bob Rossi <bob@brasko.net>
5802 * data/push.c (yyresult_get): Remove function.
5803 (YYPUSH_MORE): Add #define.
5804 (yypushparse): Modify return value.
5806 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5808 * stamp-h.in: Remove; no longer needed.
5809 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
5810 Remove config.h, config.hin, intl (no longer created).
5811 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
5814 Sync bootstrap from coreutils, as follows:
5816 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
5818 * bootstrap (symlink_to_gnulib): New function.
5819 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
5820 to copies-of-gnulib.
5821 (cp_mark_as_generated, slurp, gnulib_files):
5822 Avoid making a copy if it's the same as the old version.
5823 (gnulib_files): Add support for this variable (used by Bison).
5825 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5827 * src/getargs.c (usage): Rework to use conventions similar to
5828 coreutils, to make translation a bit easier and the code a bit
5829 smaller. Problem reported by Tim Van Holder.
5831 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
5833 Use some of gnulib's new modules, taken from coreutils.
5835 * bootstrap: Sync from coreutils, except add support for gnulib_files.
5836 * bootstrap.conf: New file.
5837 (gnulib_modules): Add configmake, inttypes, unistd.
5838 (XGETTEXT_OPTIONS): Add complain, complain_at,
5839 fatal, fatal_at, warn, warn_at, unexpected_end.
5840 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
5841 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
5843 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
5845 (GNULIB_AUTOCONF_SNIPPET): Remove.
5846 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
5848 * lib/.cvsignore: Add inttypes_.h.
5849 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
5850 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
5851 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
5852 no-longer-necessary initializations.
5853 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
5854 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
5855 use the unistd module.
5856 * src/system.h: Likewise.
5857 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
5858 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
5859 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
5860 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
5861 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
5862 * src/system.h: Include inttypes.h unconditionally, now that we
5863 use the inttypes module. Don't bother to include stdint.h, since
5864 inttypes.h now does that for us.
5865 (LOCALEDIR): Remove, now that we use the configmake module.
5866 * src/getargs.c: Include configmake.h.
5867 * src/main.c: Likewise.
5868 * src/output.c: Likewise.
5869 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
5870 not from $abs_top_builddir, since config.h moved.
5873 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
5874 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
5876 * src/parse-gram.y (symbol_declaration): Don't put statements
5877 before declarations; it's not portable to C89.
5878 * src/scan-code.l (handle_action_at): Likewise.
5880 * src/scan-code.l: Always initialize braces_level; the old code
5881 left it uninitialized and therefore had undefined behavior.
5883 Don't attempt to redefine 'assert', since it runs afoul of
5884 systems where standard headers (mistakenly) include <assert.h>.
5885 Instead, define and use our own alternative, called 'aver'.
5886 * src/reader.c: Don't include assert.h, since we no longer
5888 * src/scan-code.l: Likewise.
5889 * src/system.h (assert): Remove, replacing with....
5890 (aver): New function, taking a bool arg. All uses changed.
5891 * src/tables.c (pack_vector): Ensure that aver arg is bool,
5892 not merely an integer.
5894 2006-09-15 Bob Rossi <bob@brasko.net>
5896 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
5897 * data/c.m4 (YYPUSH): New.
5898 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
5899 * src/getargs.c (push_parser): New var.
5900 * src/getargs.h (push_parser): New declaration.
5901 * src/output.c (prepare): Add macro insertion of `push_flag'.
5902 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
5903 (prologue_declaration): Parse %push-parser.
5904 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
5905 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
5906 list of removed lines from the traces observed.
5907 (AT_CHECK_CALC_LALR): Added push parser tests.
5909 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
5911 * NEWS: Version 2.3a.
5912 * configure.ac (AC_INIT): Likewise.
5914 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
5915 "#define YYSTYPE int" that caused "make maintainer-check" to fail
5916 due to header ordering dependencies. I don't know why the #define
5919 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
5920 runtime cost when YYDEBUG is not defined, and so that some tests
5921 that used to fail now work. Problem and initial suggestion by
5923 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
5924 * data/glr.cc (b4_parser_class_name):
5925 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
5926 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
5927 (yydebug_) [YYDEBUG]: New member.
5928 (yycdebug_): Now defined only if YYDEBUG.
5929 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
5930 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
5931 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
5933 (debug_stream, set_debug_stream, debug_level, set_debug_level):
5934 Define only if YYDEBUG.
5935 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
5937 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
5938 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
5939 AT_CHECK_CALC_GLR_CC that are working now.
5941 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
5943 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
5944 We don't need them in glr.cc, and glr.c defines them.
5945 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
5946 assumes that defining it to anything is the same as defining
5947 it to 1. Problem reported by Paolo Bonzini.
5949 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
5951 * data/c.m4 (b4_null, b4_case): Define.
5952 * src/output.c (prepare_symbols): Use b4_null.
5953 (user_actions_output): Use b4_case.
5955 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
5957 * data/glr.c (b4_shared_declarations): Put start-header first,
5958 before any #includes that we generate, so that feature-test
5959 macros work. Problem reported by Michael Deutschmann in
5960 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
5961 * data/lalr1.cc: Likewise.
5962 * doc/bison.texinfo (Prologue): Document that feature-test macros
5963 should be defined before any Bison declarations.
5964 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
5965 that depend on location.hh after, not before, Bison decls, since
5966 we now include location.hh after the first user prologue.
5968 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
5969 Sander Brandenburg in
5970 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
5971 Also, fix minor white space and comment issues.
5972 (Prologue): Mention that it's better to define feature-test macros
5973 before Bison declarations. Problem reported by Michael Deutschmann.
5975 * README-cvs: Fix typo: "&" should be "&&". Problem reported
5977 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
5978 This adjusts to recent gnulib changes.
5980 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
5982 Finish implementation of per-type %destructor/%printer. Discussed
5984 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
5986 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
5987 * NEWS (2.3+): Add a description of this feature to the default
5988 %destructor/%printer description.
5989 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
5990 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
5991 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
5992 list node contains a semantic type.
5993 * src/symtab.c, src/symtab.h: Extend with a table that associates
5994 semantic types with their %destructor's and %printer's.
5995 (semantic_type_from_uniqstr, semantic_type_get,
5996 semantic_type_destructor_set, semantic_type_printer_set): New functions
5997 composing the public interface of that table.
5998 (symbol_destructor_get, symbol_destructor_location_get,
5999 symbol_printer_get, symbol_printer_location_get): If there's no
6000 per-symbol %destructor/%printer, look up the per-type before trying
6002 * tests/actions.at (Per-type %printer and %destructor): New test case.
6003 * tests/input.at (Default %printer and %destructor redeclared):
6004 Extend to check that multiple occurrences of %symbol-default in a
6005 single %destructor/%printer declaration is an error.
6006 (Per-type %printer and %destructor redeclared, Unused values with
6007 per-type %destructor): New test cases.
6009 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6011 Require default %destructor/%printer to be declared using
6012 %symbol-default instead of an empty symbol list, and start working on
6013 new per-type %destructor/%printer. Discussed at
6014 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
6015 * NEWS (2.3+): Add %symbol-default to example.
6016 * bison.texinfo (Freeing Discarded Symbols): Likewise.
6017 (Table of Symbols): Add entry for %symbol-default.
6018 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
6019 (generic_symlist, generic_symlist_item): New nonterminals for creating
6020 a list in which each item is a symbol, semantic type, or
6022 (grammar_declaration): Use generic_symlist in %destructor and %printer
6023 declarations instead of symbols.1 or an empty list.
6024 (symbol_declaration, precedence_declaration, symbols.1): Update actions
6025 for changes to symbol_list.
6026 * src/reader.c: Update for changes to symbol_list.
6027 * src/scan-code.l: Likewise.
6028 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
6029 * src/symlist.c, src/symlist.h: Extend such that a list node may
6030 represent a semantic type or a %symbol-default in addition to just an
6031 ordinary symbol. Add switched functions for setting %destructor's and
6033 * tests/actions.at, tests/input.at: Add %symbol-default to all default
6034 %destructor/%printer declarations.
6036 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
6038 Whether the default %destructor/%printer applies to a particular symbol
6039 isn't a question of whether the user *declares* that symbol (in %token,
6040 for example). It's a question of whether the user by any means
6041 *defines* the symbol at all (by simply using a char token, for
6042 example). $end is defined by Bison whereas any other token with token
6043 number 0 is defined by the user. The error token is always defined by
6044 Bison regardless of whether the user declares it with %token, but we
6045 may one day let the user define error as a nonterminal instead.
6046 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
6047 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
6048 the meaning of "user-defined".
6049 * tests/actions.at (Default %printer and %destructor for user-declared
6050 end token): Rename to...
6051 (Default %printer and %destructor for user-defined end token): ...
6054 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
6055 computation of whether to apply the default, don't maintain a list of
6056 every Bison-defined symbol. Instead, just check for a first character
6057 of '$', which a user symbol cannot have, and check for the error token.
6059 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
6061 Don't apply the default %destructor or %printer to the error token,
6062 $undefined, or $accept. This change fits the general rule that the
6063 default %destructor and %printer are only for user-declared symbols,
6064 and it solves several difficulties that are described in the new test
6066 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
6067 * tests/actions.at (Default %printer and %destructor are not for error
6068 or $undefined, Default %printer and %destructor are not for $accept):
6071 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
6073 Allow %start after the first rule.
6074 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
6075 when parsing the first rule.
6076 (check_and_convert_grammar): Search for it here after all grammar
6077 declarations have been parsed. Skip midrules, which have dummy LHS
6079 * src/symtab.c (symbol_is_dummy): New function.
6080 * src/symtab.h (symbol_is_dummy): Declare it.
6081 * tests/input.at (%start after first rule): New test.
6083 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6085 Redo some of the previous commit: add back the ability to use
6086 non-aliased/undeclared string literals since it might be useful to
6087 those declaring %token-table.
6088 * src/reader.c (check_and_convert_grammar): Undo changes in previous
6089 commit: don't worry about complaints from symbols_pack.
6090 * src/symtab.c (symbol_new, symbol_class_set,
6091 symbol_check_alias_consistency): Undo changes in previous commit: count
6092 each string literal as a new symbol and token, assign it a symbol
6093 number, and don't complain about non-aliased string literals.
6094 (symbols_pack): Since symbol_make_alias still does not decrement symbol
6095 and token counts but does still set aliased tokens to the same number,
6096 symbol_pack_processor now leaves empty slots in the symbols array.
6098 * tests/regression.at (Undeclared string literal): Remove test case
6099 added in previous commit since non-aliased string literals are allowed
6101 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
6102 remove unnecessary string literal declarations.
6103 * tests/sets.at (Firsts): Likewise.
6105 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6107 Don't allow an undeclared string literal, but allow a string literal to
6108 be used before its declaration.
6109 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
6110 symbols_pack complained.
6111 * src/symtab.c (symbol_new): Don't count a string literal as a new
6113 (symbol_class_set): Don't count a string literal as a new token, and
6114 don't assign it a symbol number since symbol_make_alias does that.
6115 (symbol_make_alias): It's not necessary to decrement the symbol and
6116 token counts anymore. Don't assume that an alias declaration occurs
6117 before any uses of the identifier or string, and thus don't assert that
6118 one of them has the highest symbol number so far.
6119 (symbol_check_alias_consistency): Complain if there's a string literal
6120 that wasn't declared as an alias.
6121 (symbols_pack): Bail if symbol_check_alias_consistency failed since
6122 symbol_pack asserts that every token has been assigned a symbol number
6123 although undeclared string literals have not.
6124 * tests/regression.at (String alias declared after use, Undeclared
6125 string literal): New test cases.
6126 (Characters Escapes, Web2c Actions): Declare string literals as
6128 * tests/sets.at (Firsts): Likewise.
6130 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
6132 In the grammar scanner, STRING_FINISH unclosed constructs and return
6133 them to the parser in order to improve error messages.
6134 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
6135 SC_BRACED_CODE, SC_PROLOGUE): Implement.
6136 * tests/input.at (Unclosed constructs): New test case.
6137 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
6140 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
6143 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
6145 Handle string aliases for character tokens correctly.
6146 * src/symtab.c (symbol_user_token_number_set): If the token has an
6147 alias, check and set its alias's user token number instead of its own,
6148 which is set to indicate the alias. Previously, every occurrence of
6149 the character token in the grammar overwrote that alias indicator with
6151 * tests/input.at (String aliases for character tokens): New test.
6153 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
6155 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
6157 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
6159 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
6160 to prevent failures when building on older platforms.
6161 Check for autopoint failure.
6162 Set XGETTEXT_OPTIONS to values that check for C format strings,
6163 so that translators are warned about them (this also helps
6164 prevent core dumps).
6166 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
6167 function, since it simplifies our code a bit.
6169 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
6170 rather than -W, so we don't get bogus warnings about sign comparisons.
6171 Add -Wpointer-arith, since that warning is useful (it reports code
6172 that does not conform to C89 and that some compilers reject).
6173 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
6174 since it's no longer needed.
6176 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
6178 Clean up scanners a bit.
6179 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
6180 definitions so gcc won't warn when obstack_for_string is unused.
6181 * src/scan-code.l: config.h and system.h are already #include'd by
6182 scan-code-c.c, so get rid of them here.
6183 * src/scan-gram.l: Likewise.
6184 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
6185 definitions rather than duplicating the rest of it.
6186 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
6188 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
6190 Suppress signed/unsigned comparison warnings for yycheck.
6191 * data/c.m4 (b4_safest_int_type): New macro.
6192 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
6193 a signed int type, cast it to b4_safest_int_type first.
6194 * data/yacc.c: Likewise.
6195 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
6198 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
6200 * doc/bison.texinfo: Fix some typos.
6202 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
6204 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
6205 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
6207 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
6208 the latest gnulib does this a different way.
6209 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
6210 translation was patched, so stop omitting it.
6212 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6214 Enable declaration of default %printer/%destructor. Make the parser
6215 use these for all user-declared grammar symbols for which the user does
6216 not declare a specific %printer/%destructor. Thus, the parser uses it
6217 for token 0 if the user declares it but not if Bison generates it as
6218 $end. Discussed starting at
6219 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
6220 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
6222 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
6223 * NEWS (2.3+): Mention.
6224 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
6225 declare a %destructor for a mid-rule's semantic value. It's just
6226 impossible to declare one specific to it.
6227 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
6228 code. Describe default %destructor form.
6229 * src/parse-gram.y (grammar_declaration): Parse default
6230 %printer/%destructor declarations.
6231 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
6232 and symbol_destructor_location_get rather than accessing the destructor
6233 and destructor_location members of struct symbol.
6234 (symbol_printers_output): Likewise but for %printer's.
6235 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
6237 * src/symtab.c (default_destructor, default_destructor_location,
6238 default_printer, default_printer_location): New static global
6239 variables to record the default %destructor and %printer.
6240 (symbol_destructor_get, symbol_destructor_location_get,
6241 symbol_printer_get, symbol_printer_location_get): New functions to
6242 compute the appropriate %destructor and %printer for a symbol.
6243 (default_destructor_set, default_printer_set): New functions to set the
6244 default %destructor and %printer.
6245 * src/symtab.h: Prototype all those new functions.
6246 * tests/actions.at (Default %printer and %destructor): New test to
6247 check that the right %printer and %destructor are called, that they're
6248 not called for $end, and that $$ and @$ work correctly.
6249 (Default %printer and %destructor for user-declared end token): New
6250 test to check that the default %printer and %destructor are called for
6251 a user-declared end token.
6252 * tests/input.at (Default %printer and %destructor redeclared, Unused
6253 values with default %destructor): New tests to check related grammar
6254 warnings and errors.
6256 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6258 Clean up handling of %destructor for the end token (token 0).
6259 Discussed starting at
6260 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
6262 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
6264 Make the skeletons consistent in how they pop the end token and invoke
6266 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
6267 state, which has token number 0, since this would invoke the
6268 %destructor for the end token.
6269 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
6270 until after shifting the end token, or else it won't be popped.
6271 * data/yacc.c (yyparse): Likewise.
6273 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
6274 it's the end token. Upon termination, destroy an unshifted lookahead
6275 even when it's the end token.
6276 * data/lalr1.cc (yy::parser::parse): Likewise.
6277 * data/yacc.c (yyparse): Likewise.
6279 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
6280 value warnings for the end token when the user gives the end token a
6283 * tests/actions.at (Printers and Destructors): Test all the above.
6285 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
6287 Update to latest gnulib and gettext versions.
6288 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
6290 (gnulib_files): Add m4/warning.m4. Don't worry about files
6291 overwritten by autopoint.
6292 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
6293 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
6295 Don't use autoreconf; instead, invoke autopoint etc. by hand,
6296 so that we can remove the intl files at a better time.
6297 (intl_files_to_remove): Remove aclocal.m4, since it gets
6298 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
6299 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
6300 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
6301 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
6302 Remove datarootdir hack; no longer needed.
6303 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
6304 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
6305 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
6307 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
6308 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
6310 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
6312 * bootstrap: Adjust to today's change to gnulib-tool by invoking
6313 it with --assume-autoconf='latest-stable'.
6315 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
6317 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
6318 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
6320 * src/muscle_tab.h (muscle_grow): Replace the header comments with
6321 those from muscle_tab.c since the old ones are misleading.
6323 2006-07-13 Akim Demaille <akim@epita.fr>
6325 Support %define "KEY" {VALUE}.
6326 * src/scan-code.h, src/scan-code.l (translate_action)
6327 (translate_rule_action, translate_symbol_action, translate_code):
6328 Return char *, not const char *.
6329 * src/parse-gram.y (declaration): Rename as...
6330 (prologue_declaration): this.
6331 (string_content): Remove this nonterminal, use STRING.
6332 (braceless, content, content.opt): New nonterminal.
6334 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
6336 * src/scan-gram.l (getargs.h): Don't include it.
6338 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
6340 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
6341 rather than a for-loop that declares a local bool variable. This
6342 should work around a compatibility problem with a Cray x1e C++
6343 compiler reported by Hung Nguyen in
6344 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
6345 The for-loop was introduced in the 2004-11-17 change but I don't
6346 know why it was needed.
6348 2006-07-12 Akim Demaille <akim@epita.fr>
6350 * data/c.m4: Comment changes.
6352 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
6354 * src/complain.c (error_message, ERROR_MESSAGE): New.
6356 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
6357 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
6359 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
6361 * NEWS: Instead of %union, you can define and use your own union type
6362 YYSTYPE if your grammar contains at least one <type> tag.
6363 Your YYSTYPE need not be a macro; it can be a typedef.
6364 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
6365 (Union Decl, Decl Summary): Document this.
6366 * data/glr.c (YYSTYPE): Implement this.
6367 * data/glr.cc (YYSTYPE): Likewise.
6368 * data/lalr1.cc (YYSTYPE): Likewise.
6369 * data/yacc.c (YYSTYPE): Likewise.
6370 * src/output.c (prepare): Output tag_seen_flag.
6371 * src/parse-gram.y (declaration, grammar_declaration):
6372 Use 'union_seen' rather than 'typed' to determine whether
6373 %union has been seen, since grammars can now be typed without
6375 (symbol_declaration, type.opt, symbol_def):
6376 Keep track of whether a tag has been seen.
6377 * src/reader.c (union_seen, tag_seen): New vars.
6379 * src/reader.h (union_seen, tag_seen, typed): Likewise.
6380 * src/scan-code.l (untyped_var_seen): New variable.
6381 (handle_action_dollar): Adjust to above changes.
6382 (handle_action_dollar, handle_action_at):
6383 Improve overflow checking for outlandish numbers.
6384 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
6385 avoid new diagnostics generated by above changes.
6386 * tests/regression.at (YYSTYPE typedef): Add test to check
6387 for type tags without %union.
6389 * src/symlist.c (symbol_list_length): Return int, not unsigned
6390 int, since callers expect int. This may need to get revisited
6391 once we have proper integer overflow checking.
6393 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
6394 object is now static.
6396 * src/getargs.c (flags_argmatch): Return void, not int,
6397 to pacify ./configure --enable-gcc-warnings.
6399 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
6400 since last_string is already defined to FLEX_PREFIX (last_string).
6402 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
6404 Implement --warnings/-W.
6405 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
6407 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
6409 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
6410 (warnings_args, warnings_types): New.
6411 (getargs, short_options, long_options): Accept -W/--warnings.
6412 Sort the options by alphabetical order, upper case letter right
6413 before its lower case.
6415 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
6417 Change %merge result type clash warnings to errors. Discussed at
6418 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
6419 * src/reader.c (record_merge_function_type): Use complain_at.
6420 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6421 declared later): Update test case results.
6423 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
6425 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
6426 to be in alphabetical order.
6427 (trace_args): Spelling fixes.
6429 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
6431 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
6432 so they don't collide with user-defined macros.
6433 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
6434 this was never guaranteed, and now that we're using gnulib stdint,
6435 which defines int_fast16_t to long int, the problem is exposed.
6437 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
6439 * data/c.m4 (b4_basename): Simplify a bit, since we don't
6440 need the full POSIX semantics (and weren't implementing them
6443 Adjust to Autoconf 2.60 and today's gnulib.
6444 * bootstrap (gnulib_modules): Add stdint.
6445 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
6446 no longer copies it.
6447 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
6448 since stdint needs the former and wcwidth (which is now required
6449 by mbswidth) needs the latter.
6450 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
6451 work around a compatibility glitch between gettext 0.14.6 and
6453 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
6454 Do not check for uintptr_t, since new stdint module does the right
6456 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
6457 Add stdint.h, stdint_.h, wcwidth.h.
6458 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
6459 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
6460 stdint.m4, wchar_t.m4, wcwidth.m4.
6461 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
6462 usual order for ../lib/*.h files.
6463 (file_name_split): Use last_component, not base_name, to adjust
6465 * src/parse-gram.h: Include <strverscmp.h> in the usual order
6466 for ../lib/*.h files.
6467 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
6468 Define unconditionally, since we now assume the stdint module.
6469 * src/scan-skel.l: Include <dirname.h>.
6470 (BASE_QPUTS): Use last_component, not base_name.
6471 * src/system.h: Include <unlocked-io.h> in the usual order
6472 for ../lib/*.h files. Include <stdint.h> unconditionally,
6473 since we now use the stdint module.
6474 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
6475 HAVE_UINTPTR_T, since we now use the stdint module.
6476 (base_name): Remove decl, since files now include <dirname.h>
6479 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
6481 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
6483 * data/yacc.c, data/glr.c, data/location.cc: Use them.
6484 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
6486 * tests/calc.at: Adjust.
6488 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
6490 * data/c.m4 (b4_basename): New.
6491 (b4_syncline): Also output the location of its invocation (from
6493 (b4_user_action, b4_define_user_action, b4_user_actions)
6494 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
6495 (b4_user_stype): New.
6496 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
6498 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6500 In the grammar file, the first column is 1 not 0 on the first line as
6501 on every other line.
6502 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
6503 * tests/input.at (Torturing the Scanner): Update output.
6505 * src/scan-gram.l (scanner_cursor): Declare it static.
6507 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6509 In warnings, say "previous declaration" rather than "first
6511 * src/symtab.c (redeclaration): Do that here.
6512 * src/reader.c (record_merge_function_type): In the case of a result
6513 type clash, report the previous declaration rather than the very first
6514 one in the grammar file.
6515 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6516 declared later): Add a third declaration to check this behavior.
6517 * tests/input.at (Incompatible Aliases): Update output.
6519 2006-06-27 Akim Demaille <akim@epita.fr>
6521 * doc/Doxyfile.in: New.
6522 * doc/Makefile.am: Use it.
6523 * src/lalr.h, src/symtab.h: Initial doxygenation.
6525 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6527 Don't miss %merge result type warnings just because the LHS types are
6528 declared after the %merge. This continues the effort of the previous
6530 * src/reader.c (get_merge_function): Don't set the merger type yet.
6531 (record_merge_function_type): New function for setting the merger type
6532 and checking for clashes.
6533 (grammar_current_rule_merge_set): Set the location of the %merge for
6535 (packgram): Invoke record_merge_function_type for each rule now that
6536 all symbol type declarations have been parsed.
6537 * src/reader.h (merger_list.type_declaration_location): New member
6538 storing the location of the first %merge from which the type for this
6539 merging function was derived.
6540 * src/symlist.h (symbol_list.merger_declaration_location): New member
6541 storing the location of a rule's %merge, if any.
6542 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6543 declared later): New test to catch the error fixed by the above patch.
6545 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6547 Get action warnings (grammar_rule_check) right even when symbol
6548 declarations appear after the rules. Discussed at
6549 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
6551 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
6552 Don't mistake the type of $$ in a midrule to be that of its parent
6554 * src/reader.c (grammar_current_rule_end): Don't invoke
6555 grammar_rule_check yet since not all symbol declarations may have been
6557 (grammar_midrule_action): Likewise.
6558 Don't record whether the midrule's $$ has been used yet since actions
6559 haven't been translated yet.
6560 Record the midrule's parent rule and its RHS index within the parent
6562 (grammar_current_rule_action_append): Don't translate the action yet
6563 since not all symbol declarations may have been parsed yet and, thus,
6564 warnings about types for $$, $n, @$, and @n can't be reported yet.
6565 (packgram): Translate the action and invoke grammar_rule_check now that
6566 all symbol declarations have been parsed.
6567 * src/scan-code.l (handle_action_dollar): Now that this is invoked
6568 after parsing the entire grammar file, the symbol list here in the case
6569 of a midrule is actually the midrule's empty RHS, so reference its
6570 parent rule's RHS where necessary.
6571 On the other hand, now that you can already know it's a midrule, you
6572 aren't forced to think $$ has the same type as its parent rule's $$.
6573 (handle_action_at): In the case of a midrule, reference the parent rule
6575 * src/symlist.c (symbol_list_new): Initialize new midrule-related
6577 (symbol_list_length): Now that this is invoked after all rules have
6578 been parsed, a NULL symbol (rather than a NULL symbol list node)
6579 terminates a rule. symbol_list_print already does this correctly.
6580 * src/symlist.h (symbol_list.midrule_parent_rule,
6581 symbol_list.midrule_parent_rhs_index): New members so that midrules can
6582 remember their relationships with their parents.
6583 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
6584 fixed by the above patch.
6585 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
6587 (Unused values): ... this old test case and...
6588 (Unused values before symbol declarations): ... this new test case.
6589 This one is the same as `Unused values' except that all symbol
6590 declarations appear after the rules in order to catch the rest of the
6591 errors fixed by the above patch.
6593 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6596 * src/reader.c (current_rule): Declare it static since it's no longer
6597 used outside this file.
6598 (grammar_current_rule_action_append): Remove redundant arguments from
6599 translate_rule_action invocation.
6600 * src/reader.h (current_rule): Remove this unused extern.
6601 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
6602 * src/scan-code.l (translate_rule_action): Likewise.
6604 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
6606 Clean up yesterday's patch.
6607 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
6609 * src/reader.c (grammar_current_rule_action_append): ... here for
6610 consistency with grammar_current_rule_symbol_append.
6611 * tests/regression.at (Braced code in declaration in rules section):
6612 Make yyerror and yylex static as usual.
6614 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
6616 Fix bug that mistakes braced code in a declaration in the rules section
6617 to be a rule action. Mentioned at
6618 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
6619 * src/scan-gram.l: Move midrule action detection from the start of the
6620 scanning of any braced code to...
6621 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
6622 action. For readability, use $2 and @2 rather than the equivalent
6624 * tests/regression.at (Braced code in declaration in rules section):
6625 New test to catch the error fixed by the above patch.
6627 Work on code readability some.
6628 * src/scan-code.l (current_rule): Get rid of this misleading and
6629 redundant declaration: it's actually extern'ed in reader.h.
6630 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
6631 translate_action): Add a rule argument and use it instead of the global
6633 (translate_rule_action): This already receives current_rule through an
6634 argument, so pass it on to translate_action instead of assigning
6635 current_rule to current_rule.
6636 (translate_symbol_action, translate_code): Pass rule = NULL to
6639 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
6641 Rename %before-definitions to %start-header and %after-definitions to
6642 %end-header. Don't use these declarations to separate pre-prologue
6643 blocks from post-prologue blocks. Add new order-independent
6644 declarations %before-header and %after-header as alternatives to the
6645 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
6646 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
6647 * NEWS (2.3+): Update for these changes.
6648 * data/glr.c (b4_before_definitions): Update to...
6649 (b4_start_header): ... this.
6650 (b4_after_definitions): Update to...
6651 (b4_end_header): ... this.
6652 * data/glr.cc: Likewise.
6653 * data/lalr1.cc: Likewise.
6654 * data/yacc.c: Likewise.
6655 * doc/bison.texinfo (The prologue): Update names, and replace remaining
6656 prologue blocks with %*-header declarations.
6657 (Calc++ Parser): Likewise.
6658 (Decl Summary): Update names.
6659 (Table of Symbols): Update description.
6660 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
6661 (PERCENT_END_HEADER): ... this.
6662 (PERCENT_BEFORE_DEFINITIONS): Update to...
6663 (PERCENT_START_HEADER): ... this.
6664 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6665 (declaration): Update token names and m4 macro names.
6666 When parsing %end-header and %start-header, invoke translate_code
6667 before muscle_code_grow, and no longer set global booleans to remember
6668 whether these declarations have been seen.
6669 Parse new %after-header and %before-header.
6670 * src/reader.c (before_definitions, after_definitions): Remove.
6671 (prologue_augment): Accept a new bool argument to specify whether to
6672 augment the pre-prologue or post-prologue.
6673 * src/reader.h (before_definitions, after_definitions): Remove these
6675 (prologue_augment): Add new bool argument.
6676 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
6677 (PERCENT_END_HEADER): ... this.
6678 (PERCENT_BEFORE_DEFINITIONS): Update to...
6679 (PERCENT_START_HEADER): ... this.
6680 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6681 * tests/actions.at (Printers and Destructors): Update names.
6683 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
6685 Add comparison operators for C++ location classes. Discussed at
6686 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
6687 * data/c++.m4 (b4_define_location_comparison): New boolean %define
6688 declaration indicating whether filename_type has an operator==. If
6689 filename_type is `std::string', it defaults to `1', `0' otherwise.
6690 * data/location.cc: Iff b4_define_location_comparison is `1', add
6691 operator== and operator!= for class position and for class location.
6694 * src/scan-action.l: Remove unused file.
6695 * src/symtab.c (symbol_printer_set): Use printer_location not
6696 destructor_location.
6697 * src/symtab.h (struct symbol): Replace incorrect source comment for
6699 * tests/input.at (Incompatible Aliases): Update output with correct
6702 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
6704 Don't put the pre-prologue in the header file. For the yacc.c code
6705 file and the glr.c header and code files, move the pre-prologue before
6706 the token definitions. Add new %before-definitions and
6707 %after-definitions to declare code that will go in both the header file
6708 and code file. Discussed at
6709 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
6710 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
6712 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
6713 * NEWS (2.3+): Describe these changes.
6714 * data/glr.c (b4_pre_prologue): Move from within to before...
6715 (b4_shared_declarations): ... this.
6716 Add new b4_before_definitions before b4_token_enums.
6717 Add new b4_after_definitions at the end.
6718 * data/glr.cc (b4_pre_prologue): Replace with...
6719 (b4_before_definitions): ... this in the header file.
6720 (b4_after_definitions): New near the end of the header file.
6721 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
6722 code file right before including the header file.
6723 (b4_before_definitions): New in the previous position of
6724 b4_pre_prologue in the header file.
6725 (b4_after_definitions): New near the end of the header file.
6726 * data/yacc.c: Clean up some m4 quoting especially in the header file.
6727 (b4_token_enums_defines): In the code file, move to right before
6728 YYSTYPE for consistency with the header file.
6729 (b4_before_definitions): New right before b4_token_enums_defines in
6730 both the header and code file.
6731 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
6732 header and code file.
6733 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
6734 of prologues for %union dependencies.
6735 (Decl Summary): In %defines description, mention the effect of
6736 %before-definitions and %after-definitions on the header file.
6737 (Calc++ Parser): Forward declare driver in a %before-definitions rather
6738 than in the pre-prologue so that make check succeeds.
6739 (Table of Symbols): Add entries for %before-definitions and
6741 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
6742 %before-definitions.
6743 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
6744 (declaration): Parse those declarations and append to
6745 b4_before_definitions and b4_after_definitions, respectively.
6746 * src/reader.c (before_definitions, after_definitions): New bools to
6747 track whether those declarations have been seen.
6748 (prologue_augment): Add to the post-prologue if %union,
6749 %before-definitions, or %after-definitions has been seen.
6750 * src/reader.h (before_definitions, after_definitions): New extern's.
6751 * src/scan-gram.l: Scan the new declarations.
6752 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
6753 prologue block in a %before-definitions or a %after-definitions based
6754 on whether the %union is declared.
6755 * tests/regression.at (Early token definitions with --yacc, Early token
6756 definitions without --yacc): Move tests for token definitions into the
6757 post-prologue since token names are no longer defined in the
6760 2006-06-20 Akim Demaille <akim@epita.fr>
6762 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
6763 (symbol_get): Use it.
6764 * src/parse-gram.y: Use it.
6766 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
6768 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
6769 build succeeds when configured with --enable-gcc-warnings.
6771 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
6773 * src/parse-gram.y (char_name): New function.
6774 (CHAR, STRING, string_content): For %printer, properly escape.
6775 (ID): Prefer fputs to fprintf.
6776 (id): Reindent to be consistent with other rules.
6777 Properly quote char.
6779 The Translation Project changed its way of publishing translations
6780 to maintainers. I haven't received any responses to my request
6781 for supporting the old way, or for documenting the new way. I
6782 have modified 'bootstrap' to use screen scraping
6783 (in this case, HTML scraping). This is unreliable and inelegant,
6784 but I don't see any better way. Yuck.
6785 * bootstrap (TP_URL, WGET_COMMAND): New vars.
6786 (get_translations): New function, which uses HTML scraping to
6787 deduce locations of latest translations.
6788 Use this function to grab both bison and bison-runtime .po files.
6789 Don't bother priming the pump for the runtime-po domain any more,
6790 as it's now translated better than bison is.
6792 2006-06-19 Akim Demaille <akim@epita.fr>
6794 * src/scan-gram.l: No longer "parse" things after `%union' until
6795 `{'. Rather, return a single "%union" token.
6796 No longer make symbols: return strings, and leave the conversion
6797 to symbols to the parser.
6798 (SC_PRE_CODE, token_type): Remove.
6799 * src/parse-gram.y (%union): New field `character'.
6802 (ID, ID_COLON): Now that the scanner no longer makes them
6803 identifiers, adjust all uses to invoke symbol_get.
6804 (id_colon): New, wraps the conversion from string to symbol.
6805 (%union): Accept a possible union_name.
6806 (symbol): Now can be a char.
6807 * data/c.m4 (b4_union_name): Leave a default value.
6808 * data/glr.c, data/yacc.c: Use it.
6810 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
6812 For associating token numbers with token names for "yacc.c", don't use
6813 #define statements unless `--yacc' is specified; always use enum
6814 yytokentype. Most important discussions start at:
6815 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
6816 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
6818 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
6819 * NEWS (2.3+): Mention.
6820 * data/c.m4 (b4_yacc_if): New.
6821 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
6823 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
6824 on token name definitions.
6825 * src/getargs.c (usage): Capitalize `Yacc' in English.
6826 * src/output.c (prepare): Define b4_yacc_flag.
6827 * tests/regression.at (Early token definitions): Test that tokens names
6828 are defined before the pre-prologue not just before the post-prologue.
6829 Remove this test case and copy to...
6830 (Early token definitions with --yacc): ... this to test #define's.
6831 (Early token definitions without --yacc): ... and this to test enums.
6833 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
6835 * NEWS: Reword the post-2.3 change to not be so optimistic about
6836 removing the old "look-ahead" spelling.
6837 Update previous look-ahead/lookahead change reports.
6838 * REFERENCES: look-ahead -> lookahead (since that's
6839 what he actually wrote).
6840 * doc/refcard.tex: look ahead -> lookahead,
6841 look-ahead -> lookahead
6843 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
6845 For consistency, use `lookahead' instead of `look-ahead' or
6846 `look_ahead'. Discussed starting at
6847 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
6849 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.

6916 2006-06-08 Joel E. Denny <jdenny@ces.clemson.edu>
6918 * src/flex-scanner.h (yytext): Remove stray `*/' in #define.
6920 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
6922 * TODO: Add request from Nelson H. F. Beebe to be able to install
6923 Bison without installing the yacc script.
6925 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
6927 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
6928 and yytext if they're already #define'd.
6929 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
6930 * src/scan-code-c.c: ... here.
6931 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
6934 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
6936 Get Bison to build again when configured with --enable-gcc-warnings.
6937 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
6939 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
6940 loc argument as it shadows a global.
6941 * src/scan-gram.l: Remove stray comma that prevents boundary_set
6944 * src/.cvsignore: Add scan-code.c.
6946 2006-06-07 Akim Demaille <akim@epita.fr>
6948 * src/scan-gram.l: Move the "add a trailing ; to actions" code
6950 * src/scan-code.l: here.
6951 * tests/input.at (Torturing the Scanner): Fix another location
6954 2006-06-07 Akim Demaille <akim@epita.fr>
6956 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
6958 2006-06-06 Akim Demaille <akim@epita.fr>
6960 Extract the parsing of user actions from the grammar scanner.
6961 As a consequence, the relation between the grammar scanner and
6962 parser is much simpler. We can also split "composite tokens" back
6964 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
6965 * src/scan-gram.l (add_column_width, adjust_location): Move to and
6967 * src/location.h, src/location.c (add_column_width)
6968 (location_compute): these.
6969 Fix the column count: the initial column is 0.
6970 (location_print): Be robust to ending column being 0.
6971 * src/location.h (boundary_set): New.
6972 * src/main.c: Adjust to scanner_free being renamed as
6974 * src/output.c: Include scan-code.h.
6975 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
6977 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
6978 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
6979 which is now, again, a separate token.
6980 Adjust all dependencies.
6981 Whereever actions with $ and @ are used, use translate_code.
6982 (action): Remove this nonterminal which is now useless.
6983 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
6984 (grammar_current_rule_action_append): Use translate_code.
6985 (packgram): Bound check ruleno, itemno, and rule_length.
6986 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
6987 (last_string, last_braced_code_loc, max_left_semantic_context)
6988 (scanner_initialize, scanner_free, scanner_last_string_free)
6989 (gram_out, gram_lineno, YY_DECL_): Move to...
6990 * src/scan-gram.h: this new file.
6991 (YY_DECL): Rename as...
6993 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
6994 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
6995 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
6996 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
6997 Move these declarations, and...
6998 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
7000 * src/flex-scanner.h: this new file.
7001 * src/scan-gram.l (rule_length, rule_length_overflow)
7002 (increment_rule_length): Remove.
7003 (last_braced_code_loc): Rename as...
7004 (gram_last_braced_code_loc): this.
7005 Adjust to the changes of the parser.
7006 Move all the handling of $ and @ into...
7007 * src/scan-code.l: here.
7008 * src/scan-gram.l (handle_dollar, handle_at): Remove.
7009 (handle_action_dollar, handle_action_at): Move to...
7010 * src/scan-code.l: here.

7021 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7023 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
7024 Use Akim's wording from
7025 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
7027 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7029 Between Bison releases, manually append `+' to the previous Bison
7030 release number, and use that as a signal to automatically print the
7031 ChangeLog's CVS Id keyword from --version. Discussed starting at
7032 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
7033 * ChangeLog: Add Id header.
7034 * configure.ac (AC_INIT): Append `+' to `2.3'.
7035 * src/.cvsignore: Add revision.c.
7036 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
7037 (BUILT_SOURCES): Add revision.c.
7038 (revision.c): New target rule. This file defines a new global variable
7039 named revision. It initializes it with either the Id from ChangeLog
7040 or, if VERSION doesn't contain `+', with the empty string.
7041 * src/getargs.c (version): Print the value of revision.
7042 * src/revision.h: Extern revision.
7044 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7046 * NEWS: Version 2.3.
7047 * configure.ac (AC_INIT): Likewise.
7049 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7051 * data/glr.c (YYRECOVERING): Define to be a function-like macro
7052 with no arguments, not as an object-like macro. This is for
7053 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
7054 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
7055 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
7058 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
7060 * src/getargs.c (usage): Back out yesterday's modification of the
7061 --help output so that we don't have to wait for translation before
7064 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
7066 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
7067 Problem reported by Akim Demaille.
7069 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
7071 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
7073 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
7075 * data/yacc.c (yy_reduce_print): Omit trailing white space in
7076 generated source code. Problem reported by Frans Englich in
7077 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
7079 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
7081 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
7082 shell, not within 'make', so that 'make' by an ordinary builder
7083 (using GNU make) does not worry about configuring gzip. This also
7084 works around a bug reported independently by Keith Thompson and by
7085 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
7086 stderr rather than stdout, messing up the build logs.
7088 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7090 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
7091 to make sure that YYID will never be unused. This fixes a 'make
7092 maintainer-check' failure caused by the recent changes to the 'Trivial
7093 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
7095 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
7097 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7099 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
7100 state before an empty RHS is always resolved here. Only the location
7101 of that state is guaranteed to be resolved, and that's enough. This
7102 fixes the remaining bug reported by Derek M. Jones in
7103 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7104 * tests/glr-regression.at (Uninitialized location when reporting
7105 ambiguity): Test the above case.
7106 Also, the embedded comments in this test case claim it checks the case
7107 of an empty RHS that has inherited the initial location. However, the
7108 corresponding LHS was already resolved, so yyresolveLocations didn't
7109 actually have reason to modify it. Fix this by forcing
7110 nondeterministic operation at the beginning of the parse.
7112 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
7114 * data/c.m4 (b4_yy_symbol_print_generate):
7115 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
7116 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
7117 of the bugs reported today by Derek M Jones in
7118 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7119 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
7120 defined to be a type name without parens or brackets.
7121 (Location Type): Similarly for YYLTYPE.
7122 * tests/regression.at (Trivial grammars): Put in a test for this
7123 bug that will be caught by 'make maintainer-check' (though not,
7124 alas, by 'make check' unless your compiler is picky).
7126 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>

7131 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
7133 * data/glr.c (yyreportTree): Make room in yystates for the state
7134 preceding the RHS. This fixes the segmentation fault reported by Derek
7136 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
7137 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
7138 to the user. Reported for yyreportTree by Derek M. Jones later in the

7142 Fix typo in Steve Murphy's name.
7144 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
7146 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
7147 checking against YYLAST that caused the parser to miss a potential
7148 alternative in its diagnostic.
7149 Problem reported by Maria Jose Moron Fernandez in
7150 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
7151 * data/lalr1.cc (yysyntax_error_): Likewise.
7152 * data/yacc.c (yysyntax_error): Likewise.
7153 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
7154 tokens, in case we run into an older C compiler.
7155 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
7156 Use them to check for the off-by-one error fixed above.
7158 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
7159 YYSIZE_T, not size_t.
7160 * tests/regression.at (Trivial grammars): New test, to catch
7161 the error fixed by the above patch.
7163 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7165 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
7167 Reported by Steve Murphy.
7169 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7171 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
7172 * data/glr.cc: b4_location_flag is now b4_locations_flag.
7174 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7176 Implement --trace=m4.
7177 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
7178 * src/output.c (output_skeleton): When set, pass -dV to m4.
7180 Factor the handling of flags in m4.
7181 * src/output.c (prepare): Rename the muscle names debug, defines,
7182 error_verbose to debug_flag, defines_flag, error_verbose_flag.
7183 * data/c.m4: Adjust.
7184 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
7185 Use b4_define_flag_if to define other b4_FLAG_if macros.
7186 (b4_location_if): As a consequence, rename as...
7187 (b4_locations_if): this, for consistency.
7188 Adjust all the skeletons.
7190 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7192 * etc/bench.pm: Shorten bench names.

7199 Adjust dependencies.
7201 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
7203 * data/c.m4 (b4_copyright): Put the special exception for Bison
7204 skeletons here, so we don't have to put it in each skeleton. All
7205 uses changed. Suggested by Akim Demaille. Also, wrap the
7206 copyright notice, in case it is longer than 80 columns. Replace
7207 comma by newline after title.
7209 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
7211 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
7212 incompatibility, not a bug. Mention that it wasn't fixed as of
7215 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7217 * examples/extexi: Enforce the precedence of concatenation over
7219 Reported by Tommy Nordgren.
7221 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7223 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
7224 with the member "token".
7225 Reported by Martin Nylin.
7227 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
7229 * data/glr.c: Switch to Bison 2.2 special-exception language in
7230 the copyright notice. Use more-regular format for titles and

7240 * data/glr.cc: Remove dead code.
7242 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
7244 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
7245 that variable and the line breaks the bootstrap. Problem reported
7246 by Juan M. Guerrero.
7248 2006-04-24 Akim Demaille <akim@lrde.epita.fr>

7266 Problem reported by Bob Rossi.
7268 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
7270 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
7271 and didn't really work.
7272 For the index, use @ifnotinfo, not @iftex.
7273 Minor cleanups of spacing and terminology.
7275 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
7277 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
7278 of AT_NAME_PREFIX when %name-prefix is not used.
7280 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
7282 Apply --prefix to C++ skeletons too: they change the namespace.
7283 The test suite already exercize these cases.
7284 * data/c++.m4 (b4_namespace): New.
7285 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
7286 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
7287 * data/yacc.c, data/glr.c: Remove a useless `[]'.
7288 * doc/bison.texinfo: Document it.
7289 (Option Cross Key): Use @multitable in all formats. It looks
7290 nicer, even in TeX outputs.
7291 (Rules): Use the same code whatever the output type is.
7292 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
7293 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
7294 * tests/calc.at: Use it, instead of hard coding `yy'.

7311 * doc/bison.texinfo (Calc++ Scanner): Use it.
7313 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
7315 Fix two nits reported by twlevo, plus one more that I discovered.
7317 * src/assoc.h (assoc_to_string): Give a name to the arg, as
7318 this is the usual Bison style.
7319 * src/location.h (location_print): Likewise.
7321 * src/reader.h (token_name): Likewise.
7323 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
7325 Fix some nits reported by twlevo.
7326 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
7327 and "POSIX". Use more-modern syntax for URLs. Mention C++
7328 and ask for Java. Don't hardwire OS version numbers. Add
7330 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
7331 * src/conflicts.c (solved_conflicts_obstack): Now static.
7333 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
7335 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
7336 page. Say "you can use it" not "you may use it" as on the web page;
7337 we're describing capabilities not granting permission.
7339 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
7341 * data/glr.c (yyresolveLocations): Rename local variables to avoid
7342 shadowing warnings. Use usual patter for iterating through RHS.
7343 * tests/glr-regression.at
7344 (Uninitialized location when reporting ambiguity):
7345 Modify yylex so that it uses its argument, rather than trying
7346 to rely on ARGSUSED (which doesn't work for gcc with warnings).
7347 const char -> char const.
7349 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
7350 Don't use tabs inside commands; it messes up 'ps'.
7351 Problem reported by twlevo.
7353 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
7355 * tests/glr-regression.at (Uninitialized location when reporting
7356 ambiguity): New test case.
7357 * data/glr.c (yyresolveLocations): New function, which uses
7359 (yyresolveValue): Invoke yyresolveLocations before reporting an
7361 * doc/bison.texinfo (Default Action for Locations): Note
7362 YYLLOC_DEFAULT's usage for ambiguity locations.
7363 (GLR Semantic Actions): Cross-reference those notes.
7365 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
7367 * tests/glr-regression.at (Leaked semantic values when reporting
7368 ambiguity): Remove unnecessary union and type declarations.
7369 (Leaked lookahead after nondeterministic parse syntax error): New test
7371 * data/glr.c (yyparse): Check for zero stacks remaining before
7372 attempting to shift the lookahead so that you don't lose it.
7374 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
7376 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
7377 * tests/glr-regression.at (Leaked semantic values when reporting
7378 ambiguity): New test case.
7379 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
7380 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
7381 now unnecessary yystackp parameter.
7382 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
7383 destructors can be called.
7385 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
7386 in existing testcases.
7388 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
7390 Don't leak semantic values for parent RHS when a user action cuts the
7391 parser, and clean up related code a bit.
7392 * tests/glr-regression.at (Leaked merged semantic value if user action
7393 cuts parse): Rename to...
7394 (Leaked semantic values if user action cuts parse): ... this. Add check
7395 for leaked parent RHS values.
7396 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
7397 between an unresolved state (non-empty chain of semantic options) and
7398 an incomplete one (signaled by an empty chain).
7399 (yyresolveStates): Document the interface. Move all manipulation of a
7400 successfully or unsuccessfully resolved yyGLRState to...
7401 (yyresolveValue): ... here so that yyresolveValue always leaves a
7402 yyGLRState with consistent data and thus is easier to understand.
7403 Remove the yyvalp and yylocp parameters since they are always just
7404 taken from the yys parameter. When reporting a discarded merged value
7405 in debugging output, note that it is incompletely merged. Document the
7407 (yyresolveAction): If resolving any of the RHS states fails, destroy
7408 them all rather than leaking them. Thus, as long as user actions are
7409 written to clean up the RHS correctly, yyresolveAction always cleans up
7410 the RHS of a semantic option. Document the interface.
7412 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
7414 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
7415 led to a segmentation fault in GNU Pascal. Problem reported
7418 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
7420 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
7421 mid-rule action inside a nonterminal symbol in order to declare a
7422 destructor for its semantic value.

7431 declarations of malloc and free, to avoid problems with
7432 incompatible declarations (using 'throw') C++'s stdlib.h. This
7433 should fix Debian bug 340012

7474 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
7476 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
7477 nodist_PROGRAMS, since we don't need to actually compile the
7478 example if we're just doing a plain 'make'. This avoids bothering
7479 the installer unnecessarily about problems due to weird C++

7487 than #include "...", and compile with -I'.'. The old method was
7488 not portable, according to Posix and the C standard, and it does
7489 not work with Sun C 5.7, where previous #line directives affect

7509 that '#include <string>' works.
7511 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
7512 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
7513 "warning: sorry: semantics of inline function static data `const
7514 unsigned char translate_table[262]' are wrong (you'll wind up with

7520 random system header somewhere that includes the equivalent of

7529 During deterministic GLR operation, user actions should be able to
7530 influence the parse by changing yychar. To make this easier to fix and
7531 to make glr.c easier to evolve in general, don't maintain yytoken in
7532 parallel with yychar; just compute yytoken when needed.
7533 * tests/glr-regression.at (Incorrect lookahead during deterministic
7534 GLR): Check that setting yychar in a user action has the intended

7539 yychar rather than *yytokenp to determine the current lookahead.
7540 Compute yytoken locally when needed.

7559 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
7560 got from <http://bro-ids.org/download.html>. The bug is that
7561 when two actions appeared in succession, the second one was
7562 scanned before the first one was added to the grammar rule
7563 as a midrule action. Bison then output the incorrect warning
7564 "parse.y:905.17-906.36: warning: unused value: $3".
7565 * src/parse-gram.y (BRACED_CODE, action): These are no longer
7566 associated with a value.
7567 (rhs): Don't invoke grammar_current_rule_action_append.
7568 (action): Invoke it here instead.
7569 * src/reader.c (grammar_midrule_action): Now extern.
7570 (grammar_current_rule_action_append): Don't invoke
7571 grammar_midrule_action; that is now the scanner's job.
7572 * src/reader.h (last_string, last_braced_code_loc):
7573 (grammar_midrule_action): New decls.
7574 * src/scan-gram.l (last_string): Now extern, sigh.

7585 All used changed. Check whether the symbol has a destructor,
7586 not whether it is typed.

7605 user can override the types.
7606 (short): #undef, to work around a bug in Pike 7.0.
7607 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
7608 (union yyalloc.yyss): Use yytype_int16 rather than short.
7610 (yysigned_char): Remove.

7826 in the yychar entry.
7827 In the yychar entry, remove mention of the local yychar case (pure
7828 parser) since this is irrelevant information when writing semantic
7829 actions and since it's already discussed in `Table of Symbols' where
7830 yychar is otherwise described as an external variable.
7831 In the yychar entry, don't call it the `current' look-ahead since it
7832 isn't when semantic actions are deferred.
7833 In the yychar and yyclearin entries, add note about deferred semantic
7835 Add yylloc and yylval entries discussing look-ahead usage.
7836 (Look-Ahead Tokens): When discussing yychar, don't call it the

7857 appropriately during nondeterministic operation.
7858 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
7859 members to store the current lookahead to be used by the deferred
7861 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
7862 from which the RHS is taken. Set the lookahead members of the new
7863 yySemanticOption according to the lookahead status for stack yyk.

7865 yyaddDeferredAction.
7866 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

7877 (Incorrect lookahead during nondeterministic GLR): New test case.
7879 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

7891 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
7893 * data/glr.c (yyresolveValue): When merging semantic options, if at
7894 least one user action succeeds but a later one cuts the parse, then
7895 destroy the semantic value before returning rather than leaking it.
7896 (yyresolveStates): If a user action cuts the parse and thus
7897 yyresolveValue fails, ignore the (unset) semantic value rather than
7898 corrupting the yyGLRState, and empty the semantic options list since
7899 the user actions should have called all necessary destructors.
7900 Simplify code with YYCHK.
7901 * tests/glr-regression.at (Corrupted semantic options if user action
7902 cuts parse): New test case.
7903 (Undesirable destructors if user action cuts parse): New test case.

8100 Undo 2005-12-01 tentative license wording change. The wording is
8101 still being reviewed by the lawyers, and we don't want to wait for
8102 them before publishing a test release. For now, revert to the

8126 for semantic values was leaked instead.
8128 2005-12-21 Joel E. Denny <address@hidden>
8130 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.

8150 destroy the RHS symbols of a rule.
8151 * data/yacc.c (yylen): Initialize to 0.

8169 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
8170 * djgpp/config.sed: Replace every occurence of the file name
8171 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
8172 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.

8201 sed out the final state number.
8203 Work around portability problem on Solaris 10: flex-generated
8204 files include <stdio.h> before <config.h>, which messes up
8205 because the latter defines __EXTENSIONS__. Address the problem
8206 by creating two new little files that include <config.h> first,
8207 then include the flex-generated files. Rewrite everyone else
8208 to include <config.h> first, as well.
8209 * lib/timevar.c: Always include "config.h".

8251 definition if 'lint' is defined.
8252 (YYID): New macro (or function, if lint).
8253 All uses of /*CONSTCOND*/0 replaced by YYID(0).
8254 * data/yacc.c: Likewise.
8255 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
8256 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
8257 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
8259 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
8260 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
8261 Use YYID(0) rather than 0, for lint.
8262 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.

8283 * NEWS: Document the following change.
8284 * data/yacc.c: Say "parser skeleton" rather than "file", since
8285 it's no longer just a file.
8286 * data/glr.c: Grant a special exception for C GLR parsers, that
8287 reads like the already-existing exception for C LALR(1) parsers.

8289 * data/lalr1.cc: Likewise.
8290 * data/location.cc: Likewise.

8552 but some people prefer the printf style.
8553 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
8554 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

8575 unused-variable warnings.
8577 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

8581 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
8583 Use unlocked I/O for a minor performance improvement on hosts like
8584 GNU/Linux and Solaris that support unlocked I/O. The basic idea
8585 is to use the gnlib unlocked-io module, and to prefer putc and
8586 puts to printf when either will work (since the latter doesn't
8587 come in an unlocked flavor).
8588 * bootstrap (gnulib_modules): Add unlocked-io.

8607 * src/system.h: Include unlocked-io.h rather than stdio.h.
8609 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as

8659 to allow support for non-posix systems. This is a no-op function
8662 * src/output.c (output_skeleton): Use end_of_output_subpipe() to

8747 local variables whose names begin with 'yy'.
8748 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
8749 Trivial changes from Joel E. Denny.
8751 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
8753 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
8754 don't use alloca any more.
8756 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
8757 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
8758 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.

8769 This works a bit better with glibc, if user code has already included
8771 * doc/bison.texinfo (Bison Parser): Document that users can't
8772 arbitrarily use malloc and free for other purposes. Document

8788 (yysyntax_error): New function.
8789 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
8790 multiple syntax errors are reported, and alloca is being used.
8791 Instead, reallocate buffers twice as big each time, so that
8792 we waste at most half the allocated memory. Start with a small
8793 (128-byte) buffer that will suffice in most cases anyway.
8794 Use yysyntax_error to do most of the work.
8796 * doc/bison.texinfo (Error Reporting, Table of Symbols):
8797 yynerrs is the number of errors reported, not the number of

8806 2005-09-19 Akim Demaille <akim@epita.fr>
8808 Remove the traits, failed experiment.
8809 It never proved useful, and anyway because of the current
8810 definition, it was not possible to have several specialization of
8811 this traits, making it useless.
8812 * data/lalr1.cc (yy:traits): Remove.
8813 Inline its definitions in the parser class.
8815 2005-09-19 Akim Demaille <akim@epita.fr>

8838 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
8839 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
8840 is not defined. This is an awful hack, but it's enough for now.
8841 All callers changed.
8842 * tests/glr-regression-at (make_value): Args are const pointers now,
8843 to avoid GCC warning.
8844 (Duplicated user destructor for lookahead): New test. Currently
8845 skipped. It fails on my host but I'm not sure it'll always fail.
8847 2005-09-16 Akim Demaille <akim@epita.fr>
8849 * src/symtab.h (struct symbol): Declare the printer and destructor
8850 as const, to avoid accidental calls to free.

8865 2005-09-16 Akim Demaille <akim@epita.fr>
8867 * data/lalr1.cc (yylex_): Remove, inline its code.
8868 (yyreport_syntax_error_): Remove, replaced by...
8869 (yysyntax_error_): this which returns a string and leaves to the
8870 caller the call to the users' error function.
8871 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
8872 Move from members of the parser object...
8873 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):

8876 2005-09-16 Akim Demaille <akim@epita.fr>
8878 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF

8897 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
8898 do anything if $@ exists. This reverts part of the 2005-07-07
8901 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
8903 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
8904 contains obsolete information and isn't worth distributing as a
8905 separate file anyway.
8906 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
8907 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

8914 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
8915 Suggested by twlevo@xs4all.nl.
8917 * data/glr.c (YYCHK1): Do not assume YYE is in range.

8919 Problem reported by twlevo@xs4all.nl.
8921 * doc/bison.texinfo: Don't use "filename", as per GNU coding
8922 standards. Use "file name" or "file" or "name", depending on
8924 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
8925 not to hack/foo.tab.c.
8926 (Calc++ Top Level): 2nd arg of main is not const.
8927 * data/glr.c: b4_filename -> b4_file_name.

9029 "make check" doesn't finish with "All 1 tests passed".
9031 * tests/regression.at (Token definitions): Don't rely on
9032 AT_PARSER_CHECK for data that contains backslashes. It currently
9033 uses 'echo', and 'echo' isn't portable if its argument contains
9034 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
9035 that the byte '\0xff' is not printable in the C locale; it is,
9036 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
9037 not printable, so use '\0x81' to test.
9039 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
9040 version of GCC, since the macro is used with non-GCC compilers.
9042 Fix core dump reported by Pablo De Napoli in
9043 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
9044 * tests/regression.at (Invalid inputs with {}): New test.
9045 * src/parse-gram.y (token_name): Translate type before using
9048 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
9049 the user's name space. All uses changed to __attribute__
9051 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
9052 Add __attribute__ ((__noreturn__)).
9054 * etc/clcommit: Remove. We weren't using it, and it failed
9055 "make maintainer-distcheck".
9056 * Makefile.maint: Merge from coreutils.
9057 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
9058 (syntax-check-rules): Change list of rules as described below.
9059 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

9069 Use grep -n, to make it easier to find violations.
9070 Use CVS_LIST and CVS_LIST_EXCEPT.
9071 (header_regexp, h_re): Remove.
9073 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
9074 (my-distcheck): Use more-modern GCC flags.
9075 (signatures, %.asc): Remove.
9076 (rel-files, announcement): Remove signatures.
9077 Restore old updating code, even though we don't use it, so
9078 that we're the same as coreutils.
9079 (alpha, beta, major): Depend on news-date-check.
9080 Make the upload commands.
9082 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
9083 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
9084 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
9085 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.

9087 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
9088 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
9089 * tests/sets.at: Likewise.
9091 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
9092 we comment out the Autoconf version number.
9093 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
9094 it's error-prone and "make maintainer-distcheck" rejects it.
9096 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
9097 Indent calls to "error" to pacify "make maintainer-distcheck",
9098 when the calls are not intended to be translated.
9099 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
9101 * src/Makefile.am (DEFS): Use +=, to pacify
9102 "make maintainer-distcheck".
9103 (bison_SOURCES): Add scan-skel.h.
9104 (sc_tight_scope): New rule, from coreutils.
9106 * src/files.c (src_extension, header_extension):
9107 Now static, not extern.
9108 * src/getargs.c (short_options): Likewise.
9109 * src/muscle_tab.c (muscle_table): Likewise.
9110 * src/parse-gram.y (current_class, current_type, current_prec):
9112 * src/reader.c (grammar_end, previous_rule_end): Likewise.
9113 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
9114 * src/main.c (main): Cast bindtextdomain and textdomain calls to
9115 void, to avoid warning when NLS is disabled.
9116 * src/output.c: Include scan-skel.h.
9117 (scan_skel): Remove decl, since scan-skel.h does this.
9119 Indent calls to "error" to pacify "make maintainer-distcheck".
9120 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
9121 * src/reader.h (gram_end, gram_lineno): New decls to pacify
9122 "make maintainer-distcheck".
9123 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
9124 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
9125 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
9126 (skel_lex_destroy, scan_skel): Move these decls to...
9127 * src/scan-skel.h: New file.
9128 * src/uniqstr.c (uniqstr_assert):
9129 Indent calls to "error" to pacify "make maintainer-distcheck".
9131 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
9134 * tests/torture.at: Revamp to avoid misuse of atoi that
9135 "make maintainer-distcheck" complained about.
9137 * examples/extexi (message): Don't print a message more than once,
9138 and omit line-number decoration that makes Emacs compile think
9139 that informative messages are worth worrying about.
9141 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
9143 * configure.ac: Update version number.
9145 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
9147 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
9148 autogenerated by the maintainer.
9149 * examples/calc++/.cvsignore: Add *.yy.
9151 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
9152 * lib/bitset_stats.c (bitset_stats_init): Likewise.
9153 * lib/bitsetv.c (bitsetv_alloc): Likewise.
9155 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
9157 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
9158 from maintainer-distcheck about casting the argument of 'free'.
9160 * NEWS: Mention recent yytname changes.
9161 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
9163 * bootstrap: For translations that have not yet been upgraded to
9164 the new runtime-po domain, prime the pump by extracting the
9165 relevant strings from the obsolete translations. This code can be
9166 removed once the bison-runtime domain has been translated by each
9169 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
9170 now that token names are already quoted.
9172 Fix problem reported by Anthony Heading.
9173 * data/glr.c (YYTOKEN_TABLE): New macro.
9174 (yytname): Define if YYTOKEN_TABLE.
9175 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
9176 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
9177 (YYERROR_VERBOSE): Define the same way the other skeletons do.
9178 * src/output.c (prepare_symbols): Output token_table_flag.
9180 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
9182 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
9183 again if the first call fails.
9185 * data/glr.c (yytnamerr): New function.
9186 (yyreportSyntaxError): Use it to dequote most string literals.
9187 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
9188 with other skeletons. All uses changed.
9189 (yytnameerr_): New function.
9190 (yyreport_syntax_error): Use it to dequote most string literals.
9191 * data/yacc.c (yytnamerr): New function.
9192 (yyerrlab): Use it to decode most string literals.
9193 * doc/bison.texinfo (Decl Summary, Calling Convention):
9194 Clarify quoting convention of yytname.
9195 * src/output.c (prepare_symbols): Quote all names. This undoes
9196 the 2005-04-17 change, which is now accomplished (mostly) via
9197 changes in the parsers as described above.
9198 * tests/regression.at (Token definitions, Web2c Actions):
9199 Undo most 2005-04-17 change here, too.
9201 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
9203 Fix more problems reported by twlevo@xs4all.nl.
9204 * tests/cxx-type.at: Don't pipe output of ./types through sed to
9205 remove trailing spaces. This loses the exit status of ./types,
9206 and isn't needed since ./types shouldn't be emitting trailing
9208 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
9209 as the stack isn't valid in that case.
9211 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
9212 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
9213 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
9214 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
9216 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
9217 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
9218 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
9221 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
9222 overly-picky compilers that reject 'char *foo = "bar";'.
9224 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
9225 to FILE * parameter, not to stderr. This fixes a typo introduced
9226 in the 2005-07-12 change.
9228 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
9229 warnings from GCC 4.
9231 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
9232 (yyglrShiftDefer, yysplitStack):
9233 Remove unused parameters b4_pure_formals. All uses changed.
9234 (yyglrShift): Remove unused parameters b4_user_formals.
9236 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
9238 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
9240 Destructor cleanups and regularization among the three skeletons.
9241 * NEWS: Document the behavior changes.
9242 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
9243 stack before failing, as the cleanup code will do it for us now.
9244 * data/lalr1.cc (yyerrlab): Likewise.
9245 * data/glr.c (yyparse): Pop everything off the stack before
9246 freeing it, so that destructors get called properly.
9247 * data/lalr1.cc (yyreturn): Likewise.
9248 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
9249 This is more consistent.
9250 * doc/bison.texinfo (Destructor Decl): Mention more reasons
9251 why destructors might be called. 1.875 -> 2.1.
9252 (Destructor Decl, Decl Summary, Table of Symbols):
9253 Some English-language cleanups for %destructor.
9254 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9255 Add output line for destructor of start symbol.
9256 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
9257 because of that same extra output line.
9259 * NEWS: Document minor wording changes in diagnostics of
9260 Bison-generated parsers.
9261 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
9262 Remove unused formals. All uses changed.
9263 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
9264 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
9265 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
9266 Rename yyoverflowab to yyexhaustedlab.
9267 When memory exhaustion occurs during syntax-error reporting,
9268 report it separately rather than in a single diagnostic; this
9270 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
9271 (Memory Exhausted): Renamed from Parser Stack Overflow.
9272 Revamp wording slightly to prefer "memory exhaustion".
9273 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
9275 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
9277 Add i18n support to the GLR skeleton. Partially fix the C++
9278 skeleton; a C++ expert needs to finish this. Remove debugging
9279 msgids; there's little point to having them translated, since they
9280 can be understood only by someone who can read the
9281 (English-language) source code.
9283 Generate runtime-po/bison-runtime.pot automatically, so that we
9284 don't have to worry about garbage getting in that file. We'll
9285 make sure after the next official release that old msgids don't
9287 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
9289 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
9291 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
9292 Fix typos in explanations of the runtime file.
9293 * bootstrap: Change gettext keyword from YYI18N to YY_.
9294 Use standard Makefile.in.in in runtime-po, since we'll arrange
9295 for backward-compatible bison-runtime.po files in a different way.
9296 * data/glr.c (YY_): New macro, from yacc.c.
9297 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
9298 Translate messages intended for users.
9299 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
9300 the wording in the other skeletons. We don't know that the memory
9302 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
9303 Use same method that yacc.c uses.
9304 Don't translate debugging messages.
9305 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
9306 it doesn't work (yet), and requires C++ expertise to fix.
9307 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
9308 Move defn to a more logical place, to be consistent with other
9310 Don't translate debugging messages.
9311 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
9312 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
9313 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
9314 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
9316 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
9317 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
9319 * tests/glr-regression.at (Badly Collapsed GLR States):
9321 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
9322 yylex should return 0 at EOF rather than aborting.
9324 Improve tests for stack overflow in GLR parser.
9325 Problem reported by twlevo@xs4all.nl.
9326 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
9328 (yyStackOverflow): Just longjmp, but with value 2 so that caller
9329 can handle the problem.
9330 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
9331 (yyparse): New local variable yyresult to record the result.
9332 Use result of setjmp to set it, rather than storing itinto
9334 (yyDone): Remove label.
9335 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
9336 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
9337 if YYABORT is used).
9338 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
9339 yyparse status; put status > 1 into diagnostic.
9340 Check that status==2 works.
9341 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
9342 Use exit status 3 for failure to open (which shouldn't happen).
9344 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
9346 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
9347 1 on syntax error; just let yyparse do its thing.
9348 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
9349 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
9350 (Exploding the Stack Size with Alloca):
9351 (Exploding the Stack Size with Malloc):
9352 Expect exit status 2, not 1, since the parser is supposed to blow
9353 its stack. Problem reported by twlevo@xs4all.nl.
9355 * data/glr.c (yyparse): Don't assume that the initial calls
9356 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
9357 Print a stack-overflow message and fail instead.
9358 Initialize the line-number information before creating the stack,
9359 so that the stack-overflow message can report line zero safely.
9361 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
9363 Fix problems reported by twlevo@xs4all.nl.
9364 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
9365 (yyuserMerge): Provide a default case if b4_mergers is empty.
9366 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
9367 * tests/glr-regression.at
9368 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
9369 Add casts to pacify C++ compilers.
9370 * tests/glr-regression.at (Improper merging of GLR delayed action
9371 sets): Declare yylex before using it.
9372 * tests/Makefile.am (maintainer-check-g++): Fix a stray
9373 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
9374 test for valgrind; valgrind is independent of g++.
9375 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
9376 for compatibility with POSIX 1003.1-2001 (if running coreutils).
9377 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
9378 Use a destructor, so that we can expand the stack. Change
9379 YYSTYPE to char * so that we can free it. Cast result of malloc.
9381 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9383 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
9384 a valgrind failure. Problem reported by twlevo@xs4all.nl.
9386 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
9388 * PACKAGING: New file, suggested by Bruno Haible and taken from
9389 similar wording in gettext's PACKAGING file.
9390 * NEWS: Mention PACKAGING.
9391 * Makefile.am (EXTRA_DIST): Add PACKAGING.

9395 * NEWS: Document recent i18n improvements.
9396 * bootstrap: Get runtime translations into runtime-po.
9397 Create runtime-po files automatically, if possible.
9398 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
9399 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
9400 does not infringe on the user's name space.
9401 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
9402 * doc/bison.texinfo (Internationalization): Revamp the English
9403 and Texinfo syntax a bit, to try to make it clearer.
9404 (Bison Options, Option Cross Key): Mention --print-localedir.
9405 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
9406 YYENABLE_NLS. Quote a bit more.
9407 * runtime-po/.cvsignore: New file.

9416 * runtime-po/Makevars: Likewise.
9417 * runtime-po/LINGUAS: Likewise.
9418 * runtime-po/de.po: Likewise; we will rely on the translation project
9419 to maintain this, so "bootstrap" should get it.
9420 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
9422 * src/main.c (main): Bind the bison-runtime domain, too.
9424 2005-07-12 Bruno Haible <bruno@clisp.org>
9426 * data/yacc.c: Include <libintl.h> when NLS is enabled.
9427 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
9428 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
9429 * runtime-po: New directory.
9430 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
9431 $(DOMAIN).pot-update rule, so that old messages are never dropped.
9432 * runtime-po/Rules-quot: New file, copied from po/.
9433 * runtime-po/quot.sed: Likewise.
9434 * runtime-po/boldquot.sed: Likewise.

9445 * Makefile.am (SUBDIRS): Add runtime-po.
9446 (aclocaldir, aclocal_DATA): New variables.
9447 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
9449 * src/getargs.c (usage): Document --print-localedir option.
9450 (PRINT_LOCALEDIR_OPTION): New enum item.
9451 (long_options): Add --print-localedir option.
9452 (getargs): Handle --print-localedir option.
9453 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
9454 (Internationalization): New section.
9456 2005-07-12 Akim Demaille <akim@epita.fr>
9458 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
9459 for consistency with the rest of the code.
9460 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
9463 2005-07-12 Akim Demaille <akim@epita.fr>
9465 * src/parse-gram.y: Use %printer instead of YYPRINT.
9467 2005-07-12 Akim Demaille <akim@epita.fr>
9469 * src/symtab.h, src/symtab.c (symbol_print): New.
9470 * src/symlist.h, src/symlist.c (symbol_list_print): New.
9471 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
9473 2005-07-12 Akim Demaille <akim@epita.fr>
9475 * data/glr.c (b4_syncline): Fix (swap) the definitions of
9476 b4_at_dollar and b4_dollar_dollar.
9478 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
9480 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
9481 and Pennello's paper.
9483 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
9485 * data/yacc.c (yyparse): Undo previous patch. Instead,
9486 set yylsp[0] and yyvsp[0] only if the initial action
9487 sets yylloc and yylval, respectively.
9489 * data/yacc.c (yyparse): In the initial action, set
9490 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
9491 This avoids the use of undefined variables if the initial
9492 action does not set yylloc and/or yylval.
9494 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
9496 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
9497 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
9498 Remove from CVS. These files are automatically generated.
9499 * examples/extexi: Clarify that this file is now part of Bison,
9500 not GNU M4, and that it works with any POSIX-compatible Awk.
9501 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
9502 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
9503 so that we also get calc++-parser.yy. Geneate it.
9504 Use $(AWK), not gawk, since any conforming Awk will do.
9505 Put comment before action, since older 'make' can't handle comment
9507 $(BUILT_SOURCES): List all built sources, not just some of them.
9508 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
9509 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
9510 $($(calc_sources_generated)): Remove unnecessary test for existence
9511 of target. (This had a shell syntax error anyway; a stray "x".)
9512 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
9514 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
9516 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
9517 implied by the other modules.
9519 2005-07-06 Akim Demaille <akim@epita.fr>
9521 Bind examples/calc++ to the package.
9522 * examples/calc++/Makefile: Remove, replaced by...

9524 * examples/calc++/test: Remove input.
9525 * examples/calc++/compile: Remove.
9526 * examples/Makefile.am: New.
9527 * configure.ac, Makefile.am: Adjust.
9528 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
9530 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
9532 * data/glr.c (yyFail): Drastically simplify; since the format argument
9533 never had any % directives, we can simply pass it to yyerror.
9534 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
9535 be modified later, as that is the usual style in glr.c.
9536 Problems reported by Paul Hilfinger.
9538 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
9539 and size overflow errors.
9540 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
9541 in case the user prolog sets feature-test macros like _GNU_SOURCE.
9542 (YYSIZEMAX): New macro.
9543 (yystpcpy): New function, taken from yacc.c.
9544 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
9545 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
9546 so that we don't have to maintain their signatures.
9547 (yyFail): Check for buffer overflow, by using vsnprintf rather
9548 than vsprintf. Allocate a bigger buffer if possible.
9549 Report an error if buffer allocation fails.
9550 (yyStackOverflow): New function.
9551 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
9552 the initialization was successful. It might fail if storage was
9554 (yyexpandGLRStack): Add more checks for storage allocation failure.
9555 Use yyStackOverflow to report failures.
9556 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
9557 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
9558 Don't assume stack number fits in int.
9559 (yysplitStack): Check for storage allocation failure.
9560 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
9561 can print diagnostics on storage allocation failure. All callers
9563 (yyresolveValue): Use yybool for boolean.
9564 (yyreportSyntaxError): Check for size-calculation overflow.
9565 This code is taken from yacc.c.
9566 (yyparse): Check for storage allocation errors when allocating
9569 2005-07-05 Akim Demaille <akim@epita.fr>
9571 Extract calc++ from the documentation.
9572 * doc/bison.texinfo (Calc++): Add the extraction marks.
9573 * examples/extexi: New, from the aborted GNU Programming 2E.
9574 Separate the different paragraph of a file with empty lines.
9575 * examples/Makefile: Use it to extract the whole calc++ example.
9577 2005-06-24 Akim Demaille <akim@epita.fr>
9579 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
9582 2005-06-22 Akim Demaille <akim@epita.fr>
9584 * doc/bison.texinfo (C++ Language Interface): First stab.
9585 (C++ Parsers): Remove.
9587 2005-06-22 Akim Demaille <akim@epita.fr>
9589 * data/lalr1.cc (yylex_): Honor %lex-param.
9591 2005-06-22 Akim Demaille <akim@epita.fr>
9593 Start a set of simple examples.
9594 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
9595 * examples/calc++/calc++-driver.hh,
9596 * examples/calc++/calc++-parser.yy,
9597 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
9598 * examples/calc++/compile, examples/calc++/test: New.
9600 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
9602 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
9603 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
9604 which stems from the 2005-05-27 patch.
9606 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
9608 * data/glr.c: Modify treatment of unused parameters to permit use
9609 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
9611 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
9613 Fix infringement on user name space reported by Janos Zoltan Szabo.
9614 * data/yacc.c (yyparse): strlen -> yystrlen.
9616 2005-05-30 Akim Demaille <akim@epita.fr>
9618 * data/lalr1.cc (_): New.
9619 Translate the various messages.
9621 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
9623 Fix infringement on user name space reported by Bruno Haible.
9624 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
9625 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
9626 the user's name space.
9627 (alloca): Include <stdlib.h> to get it, if it's not built in.
9628 (YYMALLOC, YYFREE): Define only if needed.
9629 (malloc, free): Declare, but only if needed, as this infringes on
9630 the user name space.
9632 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
9634 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
9635 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
9637 * lib/ebitset.c (min, max): Undef before defining.
9638 * lib/vbitset.c (min, max): Likewise.
9639 * lib/subpipe.c (create_subpipe): Save local variables in case
9640 vfork clobbers them.
9642 2005-05-24 Bruno Haible <bruno@clisp.org>
9644 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
9645 error message syntax used by gcc-4.0.
9647 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
9649 * README: Mention m4 1.4.3. Remove obsolete advice about
9650 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
9652 * bootstrap: Remove workaround for problem I encountered with
9653 gettext 0.14.1; it seems to be fixed now.
9655 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
9657 * NEWS: Version 2.0a.
9659 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
9660 the previous change.
9662 Various maintainer cleanups.
9663 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
9664 conftest*, for benefit of CVS commands run at the same time as
9665 "configure". Add build-aux, since "bootstrap" now creates it and
9667 * Makefile.cfg (move_if_change): Remove.
9668 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
9669 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

9671 (config.guess-url_prefix, config.sub-url_prefix):
9672 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):

9674 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
9676 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
9677 this is now the recommended name.
9678 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
9679 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
9680 ylwrap. These files now go into build-aux.
9681 * config/move-if-change: Remove.
9682 * config/prev-version.txt: Bump from 1.75 to 2.0.
9684 * bootstrap: Add stdio-safer, unistd-safer modules.
9685 Remove m4/glibc2.m4 (introduced by latest gnulib, but
9687 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
9688 fopen-safer.c, stdio-safer.h, unistd-safer.h.
9689 * lib/subpipe.c: Include "unistd-safer.h".
9690 (create_subpipe): Make sure all the newly-created
9691 file descriptors are > 2, so that diagnostics don't
9692 get sent down them (which might cause Bison to hang, in theory).
9693 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
9694 * src/files.c (xfopen): Use fopen_safer, not fopen.
9696 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
9697 yesterday's yacc.c fix.
9699 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
9701 * data/glr.c, data/lalr1.cc: Update copyright date.
9703 Fix a destructor bug reported by Wolfgang Spraul in
9704 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
9705 * data/yacc.c (yyabortlab): Don't call destructor, and
9706 don't set yychar to EMPTY.
9707 (yyoverflowlab): Don't call destructor.
9708 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
9709 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
9710 since we no longer output the message "discarding lookahead token
9713 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9715 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
9716 fix a small glitch in debugging output.
9717 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
9718 after YY_SYMBOL_PRINT where needed.
9720 (struct yyGLRState): Add some comments.
9721 (struct yySemanticOption): Add some comments.
9722 (union yyGLRStackItem): Add comment.
9724 (yymergeOptionSets): Correct this to properly perform the union,
9725 avoiding infinite reported by Michael Rosien.

9769 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
9771 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
9772 Problem reported by Ralf Menzel.
9774 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
9776 * tests/actions.at: Test that stack overflow invokes destructors.
9777 From Marcus Holland-Moritz.
9778 * data/yacc.c (yyerrlab): Move the code that destroys the stack
9780 (yyreturn): to here. That way, destructors are called properly
9781 even if the stack overflows, or the user calls YYACCEPT or
9782 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
9783 (yyoverflowlab): Destroy the lookahead.
9785 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
9787 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
9789 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
9791 * NEWS: Bison-generated C parsers no longer quote literal strings
9792 associated with tokens.
9793 * src/output.c (prepare_symbols): Don't escape strings,
9794 since users don't want to see C escapes.
9795 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
9797 * tests/input.at (Torturing the Scanner): Likewise.
9798 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
9800 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
9802 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
9803 the data size is known to be too small and we can't increase it.
9804 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
9806 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
9808 * src/parse-gram.y: Include quotearg.h.
9809 (string_as_id): Quote $1 before using it as a key, since the
9810 lexer no longer quotes it for us.
9811 (string_content): Don't strip quotes, since lexer no longer
9813 * src/scan-gram.l: Include quotearg.h.
9815 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
9816 a key, since the rest of the lexer doesn't quote it.
9817 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
9818 * tests/regression.at (Token definitions): Check for backslashes
9821 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
9822 (YYSIZE_T): Define to unsigned long int when using an older compiler.
9823 (yyparse): Revamp code to generate long syntax error message, to
9824 make it easier to translate, and to avoid problems with arithmetic
9825 overflow. Change "virtual memory" to "memory" in diagnostic, since
9826 we don't know whether the memory is virtual.
9828 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
9830 * NEWS: Bison-generated C parsers now use the _ macro to
9832 * data/yacc.c (_) [!defined _]: New macro.
9833 All English strings wrapped inside this macro.
9834 * doc/bison.texinfo (Bison Parser): Document _.
9835 * po/POTFILES.in: Include src/parse-gram.c, since it now
9836 includes translateable strings that parse-gram.y doesn't.
9838 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
9840 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
9841 reverting the 2004-10-11 change to this function.
9842 (symbol_check_alias_consistency): Don't call symbol_type_set
9843 if the type name is already correct.
9844 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
9846 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
9848 * tests/regression.at (Token definitions): Don't use a token named
9849 c, as that generates a "#define c ..." that runs afoul of buggy
9850 stdlib.h that uses the identifier c as a member of struct
9851 drand48_data. Problem reported by Horst Wente.
9853 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
9855 * bootstrap: Change translation URL from
9856 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
9857 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
9858 redirection glitches. Problem reported by twlevo@xs4all.nl.
9860 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
9862 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
9863 after operands; POSIX says this isn't portable for the c99 command.
9865 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
9867 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
9868 immediately if a data overrun has occurred; this may help us track
9869 down what may be a spurious failure on MacOS.
9871 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
9873 Respond to problems reported by twlevo@xs4all.nl.
9875 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
9877 * src/vcg.h: Comment fix.
9878 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
9879 (G_CMAX): Change to -1 instead of INT_MAX.
9881 * data/yacc.c (yyparse): Omit spaces before #line.
9883 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
9885 * src/tables.c (state_number_to_vector_number): Put it inside an
9886 "#if 0", since it's not currently used. Problem reported by
9889 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
9891 * src/output.c (escaped_output): Renamed from
9892 escaped_file_name_output, since we now use it for symbol tags as
9893 well. All uses changed.
9894 (symbol_destructors_output, symbol_printers_output):
9895 Escape symbol tags too.
9896 Problem reported by Matyas Forstner in
9897 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
9899 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
9901 * src/output.c (user_actions_output, token_definitions_output,
9902 symbol_destructors_output, symbol_printers_output): Likewise.
9903 * src/reader.c (prologue_augment): Likewise.
9904 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
9906 * src/vcg.c (output_edge): Don't quote linestyle arg.
9907 Problem reported by twlevo@xs4all.nl.
9909 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
9911 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
9912 example, reported by Derek M Jones. Also, make the example even
9913 more outrageous, to better illustrate how bad the problem is.
9915 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
9917 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
9918 putsym. Typo reported by Sebastian Piping.
9920 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
9922 * doc/bison.texinfo (Language and Grammar): some -> same
9923 (Epilogue): int he -> in the
9924 Typos reported by Sebastian Piping via Justin Pence.
9926 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
9928 * tests/glr-regression.at (Improper handling of embedded actions
9929 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
9930 embedded actions and $-N in GLR parsers", work around an Autoconf bug
9931 with dollar signs in test names.
9932 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
9933 for a similar reason.
9935 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9937 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
9938 wants to redefine G_VIEW.
9940 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
9942 * src/vcg.c (get_view_str): Remove case for normal_view.
9943 Problem reported by twlevo@xs4all.nl.
9945 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
9947 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
9948 Problem reported by twlevo@xs4all.nl.
9950 * doc/bison.texinfo: Change @dircategory from "GNU programming
9951 tools" to "Software development". Requested by Richard Stallman
9954 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
9956 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
9957 Problem reported by twlevo@xs4all.nl.
9959 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
9961 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
9962 keyword; it's not needed with modern compilers, and it doesn't
9963 affect correctness with older compilers. Suggested by
9966 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
9968 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
9969 gcc -Wswitch-default.
9970 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
9971 * data/yacc.c (yyparse): Likewise.
9973 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
9975 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
9976 already. Let config.h define any nonstandard values.
9978 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
9980 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
9981 for the benefit of slower hosts. Problem reported by
9984 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
9986 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
9987 being defined and not used.
9988 * data/lalr1.cc (yyparse): Likewise.
9989 Use "if (false)" rather than "if (0)".
9991 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
9993 * TODO: Mention that we should allow NUL bytes in tokens.
9995 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
9997 * src/scan-skel.l (<<EOF>>): Don't close standard output.
9998 Problem reported by Hans Aberg.
10000 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
10002 * src/getargs.c (version): Happy new year; update overall
10003 program copyright date from 2004 to 2005.
10005 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
10006 Problem reported by Hans Aberg.
10007 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
10008 (Output file names.): Add a test for the case when standard output
10011 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
10013 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
10014 to fix an oversight in the Bison 2.0 manual.
10016 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
10018 * NEWS: Version 2.0. Reformat the existing news items since
10019 1.875, so that related items are grouped together.
10020 * configure.ac (AC_INIT): Bump version to 2.0.
10021 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
10023 * tests/torture.at (Exploding the Stack Size with Alloca): Set
10024 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
10025 otherwise, we're not testing alloca. Unfortunately there's no
10026 simple way to consult HAVE_ALLOCA here.
10028 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
10031 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
10032 hand. This avoids a warning about comparing int to size_t when
10033 GCC warnings are enabled.
10035 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
10037 * NEWS: Bison-generated parsers no longer default to using the
10038 alloca function (when available) to extend the parser stack, due
10039 to widespread problems in unchecked stack-overflow detection.
10040 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
10041 responsibility to set it to a positive value. This lets the user
10042 specify a value that is not a preprocessor constant.
10043 * data/yacc.c (YYMAXDEPTH): Likewise.
10044 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
10045 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
10046 to be a compile-time constant. However, explain the constraints on it.
10047 Also, explain the constraints on YYINITDEPTH.
10048 (Table of Symbols): Explain that alloca is no longer the default.
10049 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
10052 * doc/bison.texinfo (Location Default Action): Mention that n must
10053 be zero when k is zero. Suggested by Frank Heckenbach.
10055 2004-12-22 Akim Demaille <akim@epita.fr>
10057 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
10058 (parser::state_type, parser::semantic_type, parser::location_type):
10059 Private, not public.
10060 (parser::parse): Return ints, not bool.
10061 Returning a bool introduces a problem: 0 corresponds to false, and
10062 it seems weird to return false on success. Returning true changes
10063 the conventions for yyparse.
10064 Alternatively we could return void and send an exception.
10065 There is no clear consensus (yet?).
10066 (state_stack, semantic_stack, location_stack): Rename as...
10067 (state_stack_type, semantic_stack_type, location_stack_type): these.
10068 Private, not public.
10069 * tests/c++.at: New.
10070 * tests/testsuite.at, tests/Makefile.am: Adjust.
10072 2004-12-21 Akim Demaille <akim@epita.fr>
10074 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
10076 2004-12-21 Akim Demaille <akim@epita.fr>
10078 Don't impose std::string for filenames.
10080 * data/lalr1.cc (b4_filename_type): New.
10081 (position::filename): Use it.
10082 (parser.hh): Move the inclusion of stack.hh and location.hh below
10083 the user code, so that needed headers for the filename type can be
10085 Forward declare them before the user code.
10086 * tests/Makefile.am (check-local, installcheck-local): Pass
10087 TESTSUITEFLAGS to the TESTSUITE.
10089 2004-12-20 Akim Demaille <akim@epita.fr>
10091 Use more STL like names: my_class instead of MyClass.
10093 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
10094 (SemanticStack, SemanticType, StateStack, StateType)
10095 (TokenNumberType, Stack, Slice, Traits, Parser::location)
10096 (Parser::value): Rename as...
10097 (location_stack, location_type, rhs_number_type, semantic_stack)
10098 (semantic_type, state_stack, state_type, token_number_type, stack)
10099 (slice, traits, parser::yylloc, parser::yylval): these.
10101 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
10103 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
10105 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
10106 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10108 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
10110 Remove uses of 'short int' and 'unsigned short int'. This raises
10111 some arbitrary limits. It uses more memory but nowadays that's
10112 not much of an issue.
10114 This change does not affect the generated parsers; that's a different
10115 task, as some users will want to conserve memory there.
10117 Ideally we should use size_t to represent all object counts, and
10118 something like ptrdiff_t to represent signed differences of object
10119 counts; but that will require more code-cleanup than I have the
10120 time to do right now.
10122 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
10123 Use size_t, not int or short int, to count objects.
10124 * src/closure.c (nritemset, closure): Likewise.
10125 * src/closure.h (nritemset, closure): Likewise.
10126 * src/nullable.c (nullable_compute): Likewise.

10131 * src/tables.c (default_goto, goto_actions): Likewise.
10133 * src/gram.h (rule_number, rule): Use int, not short int.
10134 * src/output.c (prepare_rules): Likewise.
10135 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
10136 errs, reductions): Likewise.
10137 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
10139 * src/tables.c (vector_number, tally, action_number,
10140 ACTION_NUMBER_MINIMUM): Likewise.
10141 * src/output.c (muscle_insert_short_int_table): Remove.
10143 2004-12-17 Akim Demaille <akim@epita.fr>
10145 * data/lalr1.cc: Extensive Doxygenation.
10146 (error_): Rename as...
10147 (error): this, since it is visible to the user.
10149 (Parser::message): Now an automatic variable from...
10150 (Parser::yyreport_syntax_error_): here.
10151 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
10153 * tests/input.at: Escape $.
10155 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
10157 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
10158 Parenthesize rhs to avoid obscure problems with mistakes like
10159 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
10160 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10161 b4_rhs_location): Likewise.
10162 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10163 b4_rhs_location): Likewise.
10165 2004-12-16 Akim Demaille <akim@epita.fr>
10167 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
10168 yacc.c: be sure to stay within yycheck_.
10169 * tests/actions.at: Re-enable C++ tests.
10171 2004-12-16 Akim Demaille <akim@epita.fr>
10173 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
10176 2004-12-16 Akim Demaille <akim@epita.fr>
10178 Use #define to handle the %name-prefix.
10180 * data/glr.c, data/yacc.c: Comment changes.
10181 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
10182 so that one can refer to yylex in the parser file, and have it
10183 renamed, as is the case with other skeletons.
10185 2004-12-16 Akim Demaille <akim@epita.fr>
10187 Move lalr1.cc internals into yy*.

10207 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
10209 Fix some problems reported by twlevo at xs4all.
10210 * src/symtab.c (symbol_new): Report an error if the input grammar
10211 contains too many symbols. This is better than calling abort() later.
10212 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
10213 (struct node, struct graph):
10214 Rename member expand to stretch. All uses changed.
10215 (struct graph): Remove member layoutalgorithm. All uses removed.
10216 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
10217 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
10219 (N_STRETCH): Rename from N_EXPAND. All uses changed.
10221 2004-12-15 Akim Demaille <akim@epita.fr>
10223 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
10224 Add more Doxygen comments.
10225 (symprint_, stack_print_, reduce_print_, destruct_, pop)
10226 (report_syntax_error_, translate_): Rename as...
10227 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
10228 (yypop_, yyreport_syntax_error_, yytranslate_): this.
10230 2004-12-15 Akim Demaille <akim@epita.fr>
10232 * data/lalr1.cc (lex_): Rename as...
10234 Move the trace here.
10235 Take the %name-prefix into account.
10236 Reported by Alexandre Duret-Lutz.
10238 2004-12-15 Akim Demaille <akim@epita.fr>
10240 Simplify the C++ parser constructor.
10242 * data/lalr1.cc (debug_): Rename as...
10243 (yydebug_): so that the parser's internals are always in the yy*
10246 (b4_parse_param_decl): Remove the leading comma as it is now only
10247 called as unique argument list.
10248 (Parser::Parser): Remove the constructor accepting a location and
10249 an initial debugging level.
10250 Remove from the other ctor the argument for the debugging level.
10251 (debug_level_type, debug_level, set_debug_level): New.
10253 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
10256 2004-12-15 Akim Demaille <akim@epita.fr>
10258 Remove b4_root related material: failure experiment
10259 (which goal was to allow to derive from a class).
10261 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
10262 definitions and uses.
10264 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
10266 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
10267 not 2, since it's not portable to subtract 1 from the start of an
10268 array. The new item 0 is never set or used. All uses changed.
10270 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
10271 the default definition of YYLLOC_DEFAULT. Problem reported
10272 by Frank Heckenbach.
10274 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
10276 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
10277 the normal case and one for the error case. Just use the
10278 first one uniformly. Problem reported by Frank Heckenbach.
10279 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
10280 use exactly the same macro in both places.
10281 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
10282 so that the normal-case YYRHSLOC works for the error case too.
10284 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
10285 (YYLLOC_DEFAULT): Use the same macro as glr.c.
10286 * doc/bison.texinfo (Location Default Action): Don't claim that
10287 we have an array of locations. Use the same macro for both glr
10288 and lalr parsers. Mention YYRHSLOC. Mention what happens when
10291 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>

10297 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
10299 * NEWS: Version 1.875e.
10300 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
10302 * src/scan-skel.l: Include "complain.h", for "fatal".
10304 * src/relation.h (relation_print, relation_digraph):
10305 Relation sizes are of type relation_node, not size_t (this is
10306 merely a doc fix, since the two types are equivalent).
10307 (relation_transpose): Relation sizes are of type relation_node,
10309 * src/relation.c: Likewise.
10310 (top, infinity): Now of type relation_node, not int.
10311 (traverse, relation_transpose): Use relation_node, not int.
10313 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
10314 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
10315 (yyparse): Remove unused local introduced in 2004-10-25 patch.
10317 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
10318 specifying whether the test should be skipped. Use it tp
10319 specify that the [%defines %skeleton "lalr1.cc"] tests currently
10320 fail on some hosts, and should be skipped.
10322 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
10324 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
10325 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
10326 unless otherwise specified below.
10328 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
10329 to allocate kernel_base, kernel_items, kernel_size, since
10330 they needn't be initialized to 0.
10331 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
10332 * src/closure.c (new_closure): Likewise, for itemset.
10333 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

10335 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
10336 (build_relations): Likewise for edge, states1, includes.
10337 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
10338 * src/reader.c (packgram): Likewise, for ritem, rules.
10339 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
10340 * src/relation.c (relation_digraph): Likewise for VERTICES.

10342 * src/symtab.c (symbols_token_translations_init): Likewise for
10343 token_translations.
10344 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.

10348 (goto_actions): Likewise for state_count.
10349 (pack_table): Likewise for base, pos, check.
10350 (tables_generate): Likewise for width.
10352 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
10353 for initial core. Just have a separate core, so we needn't worry
10354 about whether kernel_size and kernel_base are initialized.
10356 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
10357 kernel_size, kernel_items): Remove unnecessary initialization.
10358 * src/conflicts.c (conflicts): Likewise.
10359 * src/derives.c (derives): Likewise.

10362 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
10363 conflrow, conflict_table, conflict_list, table, check):
10366 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
10367 This is because all callers pass unsigned int.
10368 * src/closure.h (new_closure): Likewise.
10370 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
10371 (build_relations): Initialize includes[i] in all cases.
10372 * src/reader.c (packgram): Always initialize rules[ruleno].prec
10373 and rules[ruleno].precsym. Initialize members in order.
10374 * src/relation.c (relation_transpose): Always initialize new_R[i]
10376 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
10378 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
10379 conflict_list[0] was always 0, but now it isn't initialized.
10381 * src/table.c (table_grow): When conflict_table grew, the grown
10382 area wasn't cleared. Fix this.
10384 * lib/.cvsignore: Add strdup.c, strdup.h.
10385 * m4/.cvsignore: Add strdup.m4.
10387 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
10389 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
10390 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
10391 GOTO_NUMBER_MAXIMUM, since we occasionally compute
10392 ngotos + 1 without checking for overflow.
10393 (build_relations): Use END_NODE, not -1, to denote end of edges.
10394 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
10395 build_relations): Use goto_number, not int, for goto numbers.
10396 * src/tables.c (save_column, default_goto): Likewise.
10398 2004-11-23 Akim Demaille <akim@epita.fr>
10400 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
10401 of #defining from yystype.
10402 Don't typedef yystype, C++ does not need it.
10403 This lets it possible to forward declare it as union.
10405 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
10407 * bootstrap (gnulib_modules): Add extensions.
10408 Problem reported by Jim Meyering.
10410 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
10412 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
10413 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
10414 src/system.h, src/tables.c: XFREE -> free, to accommodate
10415 recent change to gnulib xalloc.h.
10416 Problem reported by Jim Meyering.
10418 2004-11-17 Akim Demaille <akim@epita.fr>
10420 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
10422 2004-11-17 Akim Demaille <akim@epita.fr>,
10423 Alexandre Duret-Lutz <adl@gnu.org>
10425 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
10427 (YYCDEBUG): Adjust.
10428 Use it instead of cdebug_.
10429 (Parser::debug_stream, Parser::set_debug_stream): New.
10430 (Parser::symprint_): Define cdebug_ for temporary backward
10432 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
10435 2004-11-17 Akim Demaille <akim@epita.fr>
10437 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
10438 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
10439 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
10440 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
10442 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
10444 * data/glr.c (yyloc_default): Remove; not used.
10445 Problem reported by Frank Heckenbach.
10447 2004-10-25 Akim Demaille <akim@epita.fr>
10449 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
10450 Introduce another definition to address simple location arrays.
10451 (yyGLRStack): New member: yyerror_range.
10452 (yyrecoverSyntaxError, yyparse): Update it.
10453 (yyrecoverSyntaxError): Use it when shifting the error token to
10454 have an accurate range, equivalent to the one computed by both
10455 yacc.c and lalr1.cc.
10456 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
10457 that column numbers start at column 0, as per GNU Coding
10458 Standards, the others tests, and the doc.
10459 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
10460 Adjust to the above change (first column is 0).
10461 And adjust the location of the "<error>", now covering the whole
10464 2004-10-22 Akim Demaille <akim@epita.fr>
10465 and Paul Eggert <eggert@cs.ucla.edu>
10467 Remove some arbitrary limits on goto numbers and relations.
10468 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
10469 initial values, since they're never used.
10470 (set_goto_map): ngotos is now unsigned, so test for overflow
10471 by seeing whether it wraps around to zero.
10472 * src/lalr.h (goto_number): Now size_t, not short int.
10473 (GOTO_NUMBER_MAXIMUM): Remove.
10474 * src/relation.c (relation_print, traverse, relation_transpose):
10475 Check for END_NODE rather than looking at sign.
10476 * src/relation.h (END_NODE): New macro.
10477 (relation_node): Now size_t, not short int.
10479 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
10481 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
10482 keyword, not an identifier. Problem reported by Baron Schwartz in
10483 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
10485 2004-10-11 Akim Demaille <akim@epita.fr>
10487 * src/symtab.c (symbol_check_alias_consistency): Also check
10488 type names, destructors, and printers.
10489 Reported by Alexandre Duret-Lutz.
10490 Recode the handling of associativity and precedence in terms
10491 of symbol_precedence_set.
10492 Accept no redeclaration at all, not even equal to the previous
10494 (redeclaration): New.
10495 Use it to factor redeclaration complaints.
10496 (symbol_make_alias): Don't set the type of the alias, let
10497 symbol_check_alias_consistency do it as for other features.
10498 * src/symtab.h (symbol): Add new member prec_location, and
10500 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
10501 * tests/input.at (Incompatible Aliases): New.
10503 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
10505 .cvsignore fixes to accommodate gnulib changes,
10506 and the practice of naming build directories "_build".
10507 * .cvsignore: Add "_*". Sort.
10508 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
10509 * m4/.cvsignore: Add "*_gl.m4".
10511 2004-10-06 Akim Demaille <akim@epita.fr>
10513 * src/parse-gram.y (add_param): Fix the truncation of trailing
10516 2004-10-05 Akim Demaille <akim@epita.fr>
10518 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
10519 whether the reducion was empty or not. This leaves room to
10520 improve the use of YYLLOC_DEFAULT in such a case.
10521 lalr1.cc is still experimental, so changing this is acceptable.
10522 And finally, there are probably not many users who changed the
10523 handling of locations in GLR, so changing is admissible too.
10525 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
10526 empty reduction, set @$ to an empty location ending the previously
10528 Adjust uses to make sure the code is triggered on empty
10530 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
10531 expected output: empty reductions have empty locations.
10533 2004-09-29 Akim Demaille <akim@epita.fr>
10535 * data/lalr1.cc: Move towards a more standard C++ coding style
10536 for templates: Class < T > -> Class<T>.
10538 2004-09-29 Akim Demaille <akim@epita.fr>
10540 * data/lalr1.cc: Reinstall the former ctor, for sake of
10541 compatibility, but warn it will be removed.
10542 Move towards a more standard C++ coding style (i.e., type *var ->
10545 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
10547 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
10548 since it's less likely to work if NULs are involved in the future.
10550 2004-09-27 Akim Demaille <akim@epita.fr>
10552 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
10554 2004-09-27 Akim Demaille <akim@epita.fr>
10556 * data/lalr1.cc (b4_parse_param_decl_1): New.
10557 (b4_parse_param_decl): Use it to have different names between attribute
10558 and argument names.
10559 (b4_cc_constructor_call): Likewise.
10561 2004-09-24 Akim Demaille <akim@epita.fr>
10563 * src/parse-gram.y (add_param): Strip the leading and trailing
10564 blanks from a formal argument declaration.
10565 (YY_LOCATION_PRINT): New.
10567 2004-09-24 Akim Demaille <akim@epita.fr>
10569 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
10570 after the location.
10572 2004-09-24 Akim Demaille <akim@epita.fr>
10574 * doc/bison.texinfo (Table of Symbols): Sort.
10576 2004-09-21 Akim Demaille <akim@epita.fr>
10578 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
10579 the useless parentheses.
10580 Suggested by Paul Eggert.
10582 2004-09-20 Akim Demaille <akim@epita.fr>
10584 Let the initial-action act on the look-ahead, and use it for the
10585 "initial push" (corresponding to an hypothetical beginning-of-file).
10586 And let lalr1.cc honor %initial-action.
10588 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
10590 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
10591 (Parser::Parser): Remove the ctor that used to initialize it.
10592 (Parser::parse): Like in the other skeletons, issue the "starting
10593 parse" message before any action.
10594 Honor %initial-action.
10595 Initialize the stacks with the lookahead.
10596 * data/yacc.c: Let $$ and @$ in %initial-action designate the
10598 Push them in the stacks.
10599 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
10601 2004-09-20 Akim Demaille <akim@epita.fr>
10603 * doc/bison.texinfo (Initial Action Decl): New.
10605 2004-09-20 Akim Demaille <akim@epita.fr>
10607 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
10608 clearer criterion to define it.
10609 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
10610 When reducing on an empty RHS, use the latest stacked location as
10612 yylloc is not always available.
10613 * data/glr.c: Likewise.
10614 Also, honor initial-actions.
10616 2004-09-20 Akim Demaille <akim@epita.fr>
10618 * data/yacc.c (YY_LOCATION_PRINT): New.
10619 Define when we know YYLTYPE's structure, i.e., when the default
10620 YYLLOC_DEFAULT is used.
10621 * data/c.m4 (b4_yysymprint_generate): Use it.
10622 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
10623 value of the result.
10624 (error_start_): Replace with...
10625 (error_range_): this location array.
10626 This allows to replace code relying on the implementation of
10627 locations by portable code.
10628 * data/yacc.c (yylerrsp): Replace with...
10629 (yyerror_range): this.
10630 Every time a token is popped, update yyerror_range[0], to have an
10631 accurate location for the error token.
10632 * data/glr.c (YY_LOCATION_PRINT): New.
10633 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
10634 deference a pointer.
10635 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
10636 report the location in %printers.
10638 * src/scan-skel.l: Instead of abort, report error messages to ease
10639 understanding skeleton scanning failures.
10641 2004-09-16 Akim Demaille <akim@epita.fr>
10643 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
10644 (iterator, const_iterator): these, to be more in the C++ spirit.
10645 Also, return reverse iterators so that when displaying the stack
10646 we display its bottom first.
10647 (Parser::stack_print_, Parser::reduce_print_): Match the messages
10649 We should probably use vector here though.
10651 2004-09-16 Akim Demaille <akim@epita.fr>
10653 Have more complete shift traces.
10655 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
10656 to report Shifts instead of ad hoc YYDPRINTF invocations,
10657 including for the error token.
10658 * data/lalr1.cc (symprint_): Output the location.
10659 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
10660 output the location within the %printer.
10661 Activate GLR tests, at least to make sure they compile properly.
10662 They still don't pass though.
10663 * tests/calc.at: Adjust expect verbose output, since now "Entering
10664 state..." is on a different line than the "Shifting" message.
10666 2004-09-08 Akim Demaille <akim@epita.fr>
10668 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
10669 Bison directive from the Bison file to the invocation of this
10670 macro, so that these directives are passed to
10671 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10672 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10673 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10674 the extra Bison directives instead of the whole series.
10675 Change the grammar so that there are recoverable errors, and
10676 unrecoverable errors. Now we can have the parser give up before
10677 consuming the whole input. As a result we now can observe that
10678 the lookahead is freed when needed.
10679 Change the parser source to parse argv[1] instead of a hard coded
10681 Simplify yylex, and give a value and location to EOF.
10682 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10683 passed directives already coded in the file.
10684 Add some tests to check the location of "error".
10685 For some tests, the C++ parser is correct, and not yacc.c.
10686 For other tests, they provide different, but unsatisfying, values,
10687 so keep the C++ value so that at least one parser is "correct"
10688 according to the test suite.
10689 (Actions after errors): Remove, this is subsumed by the
10690 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
10692 2004-09-06 Akim Demaille <akim@epita.fr>
10694 * data/lalr1.cc: Adjust the indentation of the labels.
10695 (Parser::pop): New.
10698 2004-09-06 Akim Demaille <akim@epita.fr>
10700 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
10701 argument, an informative message.
10702 Call YY_SYMBOL_PRINT.
10703 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
10704 * data/lalr1.cc (destruct_): Likewise.
10705 In addition, no longer depend on b4_yysymprint_generate and
10706 b4_yydestruct_generate to generate these functions, do it "by
10709 2004-09-03 Akim Demaille <akim@epita.fr>
10711 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
10712 invoked, yydestruct the lookahead.
10713 * tests/calc.at (Calculator $1): Update the expected lengths of
10714 traces: there is an added line for the discarded lookahead.
10715 * doc/bison.texinfo (Destructor Decl): Some rewording.
10716 Define "discarded" symbols.
10718 2004-09-02 Akim Demaille <akim@epita.fr>
10720 * data/lalr1.cc (translate_, destruct_): No reason to be static.
10722 2004-09-02 Akim Demaille <akim@epita.fr>
10724 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
10725 (YYDSYMPRINTF): Rename as...
10726 (YY_SYMBOL_PRINT): this.
10727 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
10729 Use it instead of direct symprint_ calls.
10730 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
10733 2004-09-02 Akim Demaille <akim@epita.fr>
10735 * data/lalr1.cc (b4_yysymprint_generate): New.
10736 (symprint_): New member function, defined when YYDEBUG.
10737 Use it consistently instead of token/nterm debugging output by
10739 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
10740 %printer calls to use cdebug_ when using lalr1.cc.
10742 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
10744 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
10745 with #ifdef YYDEBUG.
10747 2004-08-26 Akim Demaille <akim@epita.fr>
10749 * doc/bison.texinfo (Implementing Loops): Rename as...
10750 (Implementing Gotos/Loops): this.
10752 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
10754 Adjust to latest gnulib.
10755 * bootstrap (gnulib_modules): Add xalloc-die.
10756 Set LC_ALL=C so that file names sort consistently.
10757 Prefer the gnulib copies of gettext.m4, glibc21.m4,
10758 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
10759 uintmax_t.m4, ulonglong.m4.
10760 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
10761 po.m4 since we are now using _gl.m4 instead.
10763 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
10765 * src/scan-action.l: Remove. Scanning of semantic actions is
10766 handled in scan-gram.l.
10768 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
10770 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
10772 * src/location.h (struct): The file member is a uniqstr.
10773 (equal_boundaries): Use UNIQSTR_EQ for comparison.
10775 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
10777 Fix bug with non-%union parsers that have printers or destructors,
10778 which led to a Bison core dump. Reported by Peter Fales in
10779 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
10781 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
10782 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
10783 not to our own type.
10784 * src/output.c (symbol_destructors_output, symbol_printers_output):
10785 Don't assume %union.
10786 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
10787 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
10788 UNION-FLAG. All callers changed.
10789 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
10790 Use type char, not unsigned int, when declaring an array of char;
10791 this lets us remove a cast.
10792 (Printers and Destructors): Add non-%union test cases.
10794 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10796 * doc/bison.texinfo: Minor editorial changes, mostly to the new
10797 GLR writeups. E.g., avoid frenchspacing and the future tense,
10798 change "lookahead" to "look-ahead", and change "wrt" to "with
10801 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10803 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
10804 New sections, split off from the GLR Parsers section. Put the new
10805 Simple GLR Parser near the start of the GLR section, for clarity.
10806 Rewrite connective text.
10808 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
10810 * doc/bison.texinfo (Simple GLR Parsers): New section.
10812 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10814 * NEWS, TODO, doc/bison.texinfo:
10815 Use "look-ahead" instead of "lookahead", to be consistent.
10816 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
10817 while we're fixing "look-ahead".
10818 * src/conflicts.c (shift_set): Renamed from shiftset.
10819 (look_ahead_set): Renamed from lookaheadset.
10820 * src/print.c: Likewise.
10821 * src/getargs.c (report_args): Add "look-ahead" as the new canonical
10822 name for "lookahead".
10823 (report_types, usage): Likewise.
10824 * src/getargs.h (report_look_ahead_tokens): Renamed from
10826 * src/lalr.c (compute_look_ahead_tokens): Renamed from
10827 compute_lookaheads.
10828 (state_look_ahead_tokens_count): Renamed from state_lookaheads_count.
10829 (look_ahead_tokens_print): Renamed from lookaheads_print.
10830 * src/state.c (state_rule_look_ahead_tokens_print): Renamed from
10831 state_rule_lookaheads_print.

10846 * tests/atlocal.in (CXXFLAGS): Use it.
10848 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
10850 Fix some "make check" problems with C++ reported by
10851 Albert Chin-A-Young for Tru64 C++ in this thread:
10852 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
10854 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.

10864 C++ compiler. (trivial change)
10866 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
10868 Spent a few hours checking out which prerequisite versions the
10869 current sources actually require. I went all the way back to
10870 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
10871 a seemingly endless set of combinations of versions more recent
10872 than that. The bottom line is that the current sources require
10873 fairly recent versions of the build tools, and it'll be some work
10875 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
10876 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
10877 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
10878 Add comments explaining why those particular versions are
10881 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
10882 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
10883 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
10885 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
10886 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
10888 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
10890 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
10891 0.11.5. Suggested by Bruno Haible.
10892 * bootstrap: Remove gettext version checking.
10894 * doc/bison.texinfo (Decl Summary): Also mention that %union
10895 can depend on prerequisite types. Problem reported by Tim
10898 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
10900 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
10901 * README-alpha: Don't tell people not to package this.
10903 * bootstrap: Don't assume $(...) works; use `...` instead.
10904 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
10907 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
10908 put into the -d output file, and mention what to do if YYSTYPE is
10909 defined as a macro.
10911 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
10913 Undo change made earlier today: it caused autopoint to not bring
10914 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
10917 * bootstrap: Check that gettext version matches what's in
10918 configure.ac. Warn users to ignore robots.txt ERROR 404.
10919 * bootstrap: Undo today's earlier change (logged below).
10920 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
10922 The gettext version checking is causing more trouble than it's
10923 curing; remove it. Problem reported by Paul Hilfinger.
10925 * bootstrap: Issue a warning that one can expect a message
10926 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
10927 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
10929 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
10931 Ensure that the C++ compiler used for testing actually works on a
10932 simple test program; if not, skip the C++-related tests. Problem
10933 reported by Vin Shelton in:
10934 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
10936 * m4/cxx.m4: New file.

10941 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
10943 * data/glr.c (yylloc): Output this macro even if locations are not
10944 being generated, as the GLR parser needs it even in that case.
10945 Problem reported by Troy A. Johnson
10946 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
10948 * configure.ac (AC_INIT): Update to 1.875e.
10950 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
10952 * NEWS: Version 1.875d.
10953 * configure.ac (AC_INIT): Likewise.
10954 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
10956 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
10957 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
10958 lalr1.cc runs afoul of the first, and the last two are no longer
10959 supported by GCC 3.4.0.
10960 * README: Mention GNU m4 1.4 or later; mention m4 patches.
10961 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
10963 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>

10980 (unexpected_newline): New function.
10981 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
10984 * NEWS: Document %expect-rr.
10986 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
10987 Fix typo by replacing $1 with $option.
10988 Remove more 'intl'-related files.
10989 Don't DEFUN AM_INTL_SUBDIR twice.

10999 * src/.cvsignore: Add *.output.
11001 * src/parse-gram.y: Put copyright notice inside %{ %} so it
11002 gets copied to the output file.
11004 2004-04-28 Paul Eggert <eggert@twinsun.com>
11006 Get files from the gnulib and po repositories, instead of relying
11007 on them being in our CVS. Upgrade to latest versions of gnulib
11010 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
11011 * bootstrap: Bootstrap from gnulib and po repositories.
11012 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
11013 * README-cvs: Document these changes. Remove version numbers from
11014 mentions of build tools, since they change so often. Mention Flex.
11016 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
11017 (gl_USE_SYSTEM_EXTENSIONS): Add.
11018 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
11019 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
11021 (AC_ISC_POSIX): Remove; we no longer support this
11022 ancient OS, as it gets in the way of latest Autoconf & gnulib.
11023 (AC_HEADER_STDC): Remove: we now assume C89 or better.
11024 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
11025 Do not check for C89 headers, except for locale.h which is used
11026 by the Yacc library and must port to K&R hosts.
11027 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
11028 Do not check for C89 functions, except for setlocale which is
11029 used by the Yacc library.
11030 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
11031 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

11034 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
11035 AM_GNU_GETTEXT): Remove; now done by:
11036 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
11037 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
11040 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
11041 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
11042 Define to empty, as gnulib.mk will do the rest for us.
11043 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this

11053 (strnlen, memrchr): Remove decls; functions no longer used.
11054 Include <stpcpy.h>.

11077 Remove, as these files are now generated automatically
11078 by bootstrap or automake.
11080 * po/ChangeLog: Remove: all but one entry was a duplicate
11081 of this file, and I moved that 2000-11-02 entry here.
11083 * config/.cvsignore: Add Makefile, depcomp, install-sh.
11084 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

11100 * src/.cvsignore: Remove *_.c.
11103 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
11104 support it. (The latest stable gzip doesn't.)
11106 2004-04-27 Paul Eggert <eggert@twinsun.com>
11108 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
11109 case, as stos_ is now used by destructors due to the 2004-02-09
11112 Remove more K&R C support.
11113 * lib/libiberty.y (PARAMS): Remove. All uses removed.

11131 with latest obstack.h.
11132 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
11133 to procedure types, as obstack.h now does that for us.

11140 test whether it can stand alone.
11142 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
11143 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
11144 unused declaration.

11147 the union, because empty unions aren't allowed in C. Caught

11218 2004-03-08 Paul Eggert <eggert@gnu.org>
11220 Add support for hex token numbers. Suggested by Odd Arild Olsen in
11221 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.

11235 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
11236 compilers. This fixes a problem with Intel's C++ compiler being
11237 chatty, reported by Guido Trentalancia in
11238 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
11240 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
11242 Support %destructor and merge error locations in lalr1.cc.
11244 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
11245 (Parser::stos_): Define unconditionally.

11250 token which are discarded.
11251 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
11252 error_start_ when erroneous token are discarded.
11253 (Parser::parse) <yyerrlab1>: Compute the location of the error
11254 token so that it covers all the discarded tokens.
11255 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
11256 it can be called with `%skeleton "lalr1.cc"', and do that.
11258 2004-02-02 Paul Eggert <eggert@twinsun.com>
11260 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
11261 $(top_srcdir)/lib and ../lib. This fixes a bug reported
11262 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
11263 There's no need to mention top_builddir since Automake does that
11265 (INCLUDES): Remove, as Automake says it's obsolescent.
11266 Contents migrated into AM_CPPFLAGS as described above.
11267 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
11269 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11271 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
11272 (yyreportSyntaxError): Handle case where lookahead token is
11275 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11277 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
11278 resulting parsers are compilable with C++.
11280 2003-12-23 Paul Eggert <eggert@twinsun.com>
11282 * config/depcomp, config/install-sh: Sync with Automake 1.8.
11283 * src/output.c (output_skeleton): Rename local var.
11284 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
11285 Bison tokens, as this runs afoul of the 2003-10-07 change that
11286 disallowed NUL bytes in character constants or string literals.
11288 * tests/local.at: Require Autoconf 2.59's Autotest.
11289 * tests/testsuite.at: Don't include local.at, since we now assume
11290 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
11292 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
11293 multiple inclusion warnings.
11295 2003-12-02 Akim Demaille <akim@epita.fr>

11305 2003-10-07 Paul Eggert <eggert@twinsun.com>
11307 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
11308 if testsuite doesn't exist.
11310 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
11311 literals, unfortunately.
11312 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
11313 Complain about NUL bytes in character constants or string literals.
11315 2003-10-05 Paul Eggert <eggert@twinsun.com>
11317 * NEWS: Don't document %no-default-prec, as it's still
11319 * doc/bison.texinfo: Document %no-default-prec only if
11320 the defaultprec flag is set. Normally it's not.
11322 2003-10-04 Paul Eggert <eggert@twinsun.com>
11324 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
11325 non-modifiable lvalue, instead of a modifiable one.
11326 * doc/bison.texinfo (Actions): Document that $$ can
11327 be assigned to. Do not claim that $$ and $N are
11328 array element references: user code should not rely on this.
11330 2003-10-01 Paul Eggert <eggert@twinsun.com>
11332 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.

11342 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
11343 * src/print_graph.c (print_graph): Adjust.
11345 2003-09-30 Frank Heckenbach <frank@g-n-u.de>

11362 a typo in the 2003-08-25 patch.
11364 2003-08-27 Akim Demaille <akim@epita.fr>
11366 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
11369 2003-08-26 Akim Demaille <akim@epita.fr>
11371 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
11372 "<\#" to avoid magic from Gnus when posting parts of this script.
11374 2003-08-26 Akim Demaille <akim@epita.fr>
11376 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
11377 (Parser::parse): here.
11378 Adjust: nerrs and errstatus is now replaced by...
11379 (Parser::nerrs_, Parser::errstatus_): New.
11381 2003-08-25 Akim Demaille <akim@epita.fr>
11383 * config/announce-gen, Makefile.cfg: New.
11384 * Makefile.am: Adjust.

11386 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
11388 2003-08-25 Akim Demaille <akim@epita.fr>
11390 When reducing initial empty rules, Bison parser read an initial
11391 location that is not defined. This results in garbage, and that
11392 affects Bison's own parser. Therefore we need (i) to extend Bison
11393 to support a means to initialize this location, and (ii) to use
11394 this CVS Bison to fix CVS Bison's parser.
11396 * src/reader.h, reader.c (epilogue_augment): Remove, replace
11398 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
11399 * src/parse-gram.y: Adjust.
11400 (%initial-action): New.
11401 (%error-verbose): Since we require CVS Bison, there is no reason
11403 * src/scan-gram.l: Adjust.
11404 * src/Makefile.am (YACC): New, to make sure we use our own parser.
11405 * data/yacc.c (yyparse): Use b4_initial_action.
11407 2003-08-25 Akim Demaille <akim@epita.fr>
11409 * doc/bison.texinfo: Don't promote stdout for error messages.
11411 2003-08-25 Akim Demaille <akim@epita.fr>
11413 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
11414 From Alexandre Duret-Lutz.

11425 2003-08-25 Akim Demaille <akim@epita.fr>
11427 * data/lalr1.cc (Parser::reduce_print_): New.
11430 2003-08-25 Akim Demaille <akim@epita.fr>
11432 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
11433 error recovery loops. This patch is based on
11434 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
11435 Also, augment the similarity between lalr1.cc and yacc.c.
11436 Note: the locations of error recovery rules are not correct yet.
11438 * data/lalr1.cc: Comment changes to augment the similarity between
11439 lalr1.cc and yacc.c.
11440 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
11441 (yyerrlab1): Remove, but where it used to be (now the bottom part of
11442 yyerrlab), when hitting EOF, pop the whole stack here instead of
11443 merely falling thru the default error handling mechanism.
11444 (yyerrorlab): New label, with the old contents of YYERROR,
11445 plus the following change: pop the stack of rhs corresponding
11446 to the production that invoked YYERROR. That is how Yacc
11447 behaves (required by POSIX).
11448 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
11451 2003-08-25 Akim Demaille <akim@epita.fr>
11453 Tune local.at so that people can "autom4te -l autotest calc.at -o
11454 calc" for instance, to extract a sub test suite.
11456 * tests/testsuite.at: Move the initialization, Autotest version
11457 requirement, and AT_TESTED invocation into...
11458 * tests/local.at: here.
11459 * tests/testsuite.at: Include it for compatibility with Autoconf
11461 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
11464 2003-08-04 Paul Eggert <eggert@twinsun.com>
11466 Rework code slightly to avoid gcc -Wtraditional warnings.
11467 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
11468 The returned value is now stored in *YY0. All callers changed.
11469 * src/output.c (merge_output): Adjust to the above change.
11471 2003-07-26 Paul Eggert <eggert@twinsun.com>
11473 * data/glr.c (YYASSERT): New macro.
11474 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
11475 yyresolveStates, yyprocessOneStack):
11476 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
11477 Derived from a suggestion by Frank Heckenbach.
11479 2003-07-25 Paul Eggert <eggert@twinsun.com>
11481 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
11482 for portability to K&R C (after ansi2knr, presumably). See
11483 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
11484 by Frank Heckenbach, though I have omitted the structure-initialization
11485 part of his glr-knr.diff patch since I recall that the Portable
11486 C Compiler didn't require that change.
11488 Let the user specify how to allocate and free memory.
11489 Derived from a suggestion by Frank Heckenbach in
11490 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
11491 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
11492 All uses of free, malloc, realloc changed to use these macros,
11493 and unnecessary casts removed.
11494 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
11496 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
11498 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
11499 use s.empty() rather than s == "" to test for empty string; see
11500 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
11503 2003-06-25 Akim Demaille <akim@epita.fr>
11505 * config/depcomp, config/install-sh: Update from masters.
11507 2003-06-20 Paul Eggert <eggert@twinsun.com>
11509 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
11510 and return properly parenthesized result.
11511 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
11512 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
11513 Remove unnecessary parentheses from uses.
11514 * doc/bison.texinfo (Location Default Action): Describe the
11515 conventions for parentheses.
11517 2003-06-19 Paul Eggert <eggert@twinsun.com>
11519 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
11520 yyreportTree): Do not assume that size_t is the same width as int,
11521 when printing sizes. Print sizes using an unsigned format.
11522 Problem reported by Frank Heckenbach in
11523 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
11525 Port to Forte Developer 7 C compiler.
11526 * data/glr.c (struct YYLTYPE): If locations are not being used,
11527 declare a single dummy member, as empty structs do not conform
11529 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
11530 the Forte Developer 7 C compiler complains that end-of-loop
11531 code is not reached.
11533 2003-06-17 Paul Eggert <eggert@twinsun.com>
11535 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
11536 avoid warnings from picky compilers about redefinition of PARAMS.
11538 2003-06-17 Paul Eggert <eggert@twinsun.com>
11542 * NEWS: Document 1.875b.
11544 * lib/bbitset.h: Do not include config.h; that's the includer's job.
11545 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
11546 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
11547 Don't use 'index' in comments, as it's a builtin fn on some hosts.
11548 * lib/bitset_stats.c: Include gettext.h unconditionally, as
11549 per recent gettext manual's suggestion.
11550 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
11551 Use prototypes, not old-style definitions.
11552 * lib/lbitset.c (lbitset_unused_clear): Likewise.
11553 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
11554 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
11555 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,

11569 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
11570 * lib/vbitset.c, lib/vbitset.h: New files.
11571 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
11572 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
11575 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
11576 `How Can I Reset @code{yyparse}', since texinfo does not allow
11577 arbitrary @ in node names.
11579 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
11580 shouldn't be needed according to the gettext 0.12.1 documentation
11581 but which seem to be needed anyway: codeset.m4 glibc21.m4
11582 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
11583 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

11593 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
11594 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
11595 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
11596 (MOSTLYCLEANFILES): New var.

11604 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
11605 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
11606 the tests right now.
11607 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
11608 yyerror are declared before use; C99 requires this.
11610 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11612 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
11614 (yyrecoverSyntaxError): Correct the logic for setting and testing
11616 Correct comment on handling EOF.
11617 Allow states with only a default reduction, rather than failing
11618 (I can't quite reconstruct why these were not allowed before).
11620 Fixes to avoid problem that $-N rules in GLR parsers can cause
11621 buffer overruns, corrupting state.
11623 * src/output.c (prepare_rules): Output max_left_semantic_context
11625 * src/reader.h (max_left_semantic_context): New variable declaration.
11626 * src/scan-gram.l (max_left_semantic_context): Define.
11627 (handle_action_dollar): Update max_left_semantic_context.
11628 * data/glr.c (YYMAXLEFT): New definition.
11629 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
11630 (yyresolveAction): Ditto.
11632 Fixes to problems with location handling in GLR parsers reported by
11633 Frank Heckenbach (2003/06/05).
11635 * data/glr.c (YYLTYPE): Make trivial if locations not used.
11636 (YYRHSLOC): Add parentheses, and define only if locations used.
11637 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
11638 locations not used.

11640 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
11642 * tests/cxx-type.at: Exercise location information; update tests
11643 to differentiate output with and without locations.
11644 Remove forward declarations of yylex and yyerror---caused errors
11645 because default YYLTYPE not yet defined.
11646 Change semantic actions to compute strings, rather than printing
11647 them directly (to test proper passing of semantics values). Change
11648 output to prefix notation and update test data and expected results.
11649 (yylex): Track locations.
11650 (stmtMerge): Return value rather than printing, and include arguments
11653 2003-06-03 Paul Eggert <eggert@twinsun.com>
11655 Avoid warnings generated by GCC 2.95.4 when Bison is
11656 configured with --enable-gcc-warnings.
11657 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
11658 yy::]b4_parser_class_name[::translate_,
11659 yy::Stack::operator[] (unsigned),
11660 yy::Stack::operator[] (unsigned) const,
11661 yy::Slice::operator[] (unsigned),
11662 yy::Slice::operator[] (unsigned) const):
11663 Rename local vars to avoid warnings.
11664 * tests/glr-regression.at (Improper handling of embedded actions
11665 and $-N in GLR parsers): Remove unused local variable from yylex.
11666 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
11667 (void) as arg when not pure, since we now assume C89 when building
11668 Bison. Pacify GCC by using parameter.
11670 2003-06-02 Paul Eggert <eggert@twinsun.com>
11672 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
11673 yy::Location::lines, yy::Location::columns): Rename arguments
11674 to avoid shadowing; this removes a warning generated by GCC 3.3.
11676 2003-06-01 Paul Eggert <eggert@twinsun.com>
11678 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
11679 to g++, as GCC 3.3 complains if you do it.
11680 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
11681 everything that WARNING_CFLAGS has, except omit warnings
11682 not suitable for C++.
11683 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
11684 * tests/atlocal.in (CXXFLAGS): New var.
11685 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
11687 Fix a GLR parser bug I reported in February; see
11688 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
11689 The problem was that GLR parsers did not conform to the C standard,
11690 because actions like { $1 = $2 + $3; } expanded to expressions
11691 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11692 to a local variable. The C standard says that expressions
11693 like (var = f ()) + (var = f ()) have undefined behavior.
11694 Another problem was that GCC sometimes issues warnings that
11695 yyfill and its parameters are unused.
11697 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11698 as possibly unused.
11699 (yyfill): New function.
11701 (yyuserAction): Change type of yynormal to bool, so that it matches
11702 the new yyfill signature. Mark it as possibly unused.
11705 Follow up on a bug I reported in February, where a Bison-generated
11706 parser can loop. Provide a test case and a fix for yacc.c. I
11707 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11708 The original bug report is in:
11709 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
11711 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11712 macro's size was becoming unwieldy.
11713 (yyerrlab): Do not discard an empty lookahead symbol, as this
11714 might destroy garbage.
11715 (yyerrorlab): New label, with the old contents of YYERROR,
11716 plus the following change: pop the stack of rhs corresponding
11717 to the production that invoked YYERROR. That is how Yacc
11718 behaves, and POSIX requires this behavior.
11719 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11720 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11721 Define 'alarm' to do nothing if unistd.h is not available.
11722 Add a new rule "exp: '-' error;" to test the above change to
11723 data/yacc.c. Use 'alarm' to abort any test taking longer than
11724 10 seconds, as it's probably looping.
11725 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11726 Also, the new yacc.c generates two fewer diagnostics for an
11729 2003-05-24 Paul Eggert <eggert@twinsun.com>
11731 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
11732 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
11733 This fixes a problem reported by John Bowman when the Compaq/HP
11734 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
11735 -ansi -Wall -gall).
11736 * data/yacc.c (union yyalloc): Likewise.
11737 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
11739 Switch from 'int' to 'bool' where that makes sense.

11744 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
11745 Return or accept bool, not int. All callers changed.
11746 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
11747 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.
11748 * lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_,

11765 lbitset_xor_cmp): Likewise.
11766 * lib/bbitset.h: Include <stdbool.h>.
11767 (struct bitset_vtable): The following members now return bool, not
11768 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
11769 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
11771 * src/conflicts.c (count_rr_conflicts): Likewise.
11772 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
11774 * lib/ebitset.c (ebitset_obstack_init): Likewise.

11778 graph_flag): Likewise.

11788 * src/lalr.c (build_relations): Use bool, not int.
11789 * src/nullable.c (nullable_compute): Likewise.
11790 * src/print.c (print_reductions): Likewise.
11791 * src/tables.c (action_row, pack_vector): Likewise.
11792 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
11793 * src/output.c (prepare): Use it.
11794 * src/output.c (token_definitions_output,
11795 symbol_destructors_output, symbol_destructors_output): Use string,
11796 not boolean integer, to keep track of whether to output separator.
11797 * src/print_graph.c (print_core): Likewise.
11798 * src/state.c (state_rule_lookaheads_print): Likewise.
11800 * config/install-sh: Sync from automake 1.7.5.
11802 2003-05-14 Paul Eggert <eggert@twinsun.com>
11804 * src/parse-gram.y (rules_or_grammar_declaration): Require a
11805 semicolon after a grammar declaration, in the interest of possible
11806 future changes to the Bison input language.
11807 Do not allow a stray semicolon at the start of the grammar.
11808 (rhses.1): Allow one or more semicolons after any rule, including
11809 just before "|" as required by POSIX.
11810 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
11813 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11815 %parse-param support for lalr1.cc.
11817 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
11818 b4_cc_constructor_calls, b4_cc_constructor_call,
11819 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
11821 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
11822 parse-param arguments.
11823 (yy::b4_parser_class_name): Declare instance variables to
11824 hold parse-param arguments.
11825 * tests/calc.at: s/value/semantic_value/ because value clashes
11826 with a member of yy::b4_parser_class_name. Adjust C++ code
11827 to handle %parse-param. Enable %parse-param test in C++.
11829 2003-05-12 Paul Eggert <eggert@twinsun.com>
11831 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
11832 English a bit. Fix fclose typo. Change "const char" to "char
11833 const", and use ANSI C rather than K&R for "main". Suggest
11834 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
11835 and suggest yy_switch_to_buffer.
11837 2003-05-05 Paul Eggert <eggert@twinsun.com>
11839 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
11840 C89. This avoids a diagnostic on compilers that define __STDC__
11841 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
11842 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11844 2003-05-03 Paul Eggert <eggert@twinsun.com>
11846 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
11847 Do not overrun array bounds.
11848 This should fix a bug reported today by Olatunji Oluwabukunmi in
11849 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
11851 2003-04-29 Akim Demaille <akim@epita.fr>
11853 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
11854 * src/getargs.c, src/getargs.h: here, as bool, not int.
11855 (nondeterministic_parser): New.
11856 * src/parse-gram.y, src/scan-gram.l: Support
11857 %nondeterministic-parser.
11858 * src/output.c (prepare): Use nondeterministic_parser instead
11859 of glr_parser where appropriate.
11860 * src/tables.c (conflict_row, action_row, save_row)
11861 (token_actions, token_actions, pack_vector): Ditto.
11863 2003-04-29 Akim Demaille <akim@epita.fr>
11865 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
11867 2003-04-29 Akim Demaille <akim@epita.fr>
11869 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
11870 with %pure-parser and %locations to exercise the patch from Yakov
11873 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
11875 * data/yacc.c: (b4_lex_param): Corrected for the case where
11876 %lex-param is provided and %pure-parser isn't.
11878 2003-04-27 Paul Eggert <eggert@twinsun.com>
11880 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
11881 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
11882 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
11883 if it is not defined.
11884 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
11886 2003-04-26 Paul Eggert <eggert@twinsun.com>
11888 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
11889 Declare to be of type suitable for the ninf value itself, not of
11890 type suitable for the corresponding table, since the latter might
11891 be unsigned but the ninf value might be negative. This fixes a
11892 bug reported by Alexandre Duret-Lutz in
11893 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
11895 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
11896 invokes it. We shouldn't invoke it twice because it will attempt
11897 to put error.o in the archive twice. This fixes a glitch reported
11898 by Martin Mokrejs in
11899 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11901 2003-04-21 Paul Eggert <eggert@twinsun.com>
11903 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
11906 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
11908 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
11909 Fix obvious typo that results in uncompilable GLR parsers
11910 when both %pure-parser and %locations are used. (trivial change)
11912 2003-04-17 Paul Eggert <eggert@twinsun.com>
11914 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
11915 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
11916 Do not insert the expected token via unput, as this runs afoul
11917 of a POSIX-compatibility bug in flex 2.5.31.
11918 All uses changed to BEGIN the parent state,
11919 since we no longer insert the expected token via unput.
11920 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
11921 that is no longer emitted after the above change.
11923 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
11924 the first one. This change is from Paul Hilfinger, and it fixes
11925 regression reported by Werner Lemberg in
11926 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
11928 (resolve_sr_conflict): Don't invoke state_errs_set
11929 unless one or more tokens have been explicitly made errors.
11930 Otherwise, the above change causes Bison to abort.
11932 * tests/existing.at (GNU pic Grammar): New test case, taken from
11935 2003-03-31 Akim Demaille <akim@epita.fr>
11937 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
11939 2003-03-31 Akim Demaille <akim@epita.fr>
11941 * src/output.c (prepare_symbols): Avoid trailing spaces in the
11944 2003-03-31 Akim Demaille <akim@epita.fr>
11946 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
11947 From Paul Hilfinger.
11949 2003-03-29 Akim Demaille <akim@epita.fr>
11951 * m4/error.m4: Do not put under dynamic conditions some code which
11952 expansion is under static control.
11954 2003-03-29 Akim Demaille <akim@epita.fr>
11956 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
11958 2003-03-29 Akim Demaille <akim@epita.fr>
11960 * doc/bison.texinfo (Strings are Destroyed): New.
11962 2003-03-13 Paul Eggert <eggert@twinsun.com>
11964 * .cvsignore: Add configure.lineno.
11965 * src/.cvsignore: Add yacc.
11966 * tests/.cvsignore: Add testsuite.log.
11967 * doc/fdl.texi: Sync with latest FSF version.
11969 2003-03-12 Paul Eggert <eggert@twinsun.com>
11971 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
11972 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
11973 cursor, instead of leaving it undefined. This fixes a bug
11974 reported by Tim Van Holder in
11975 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
11976 * tests/input.at (Torturing the Scanner): Test the scanner on
11977 an empty input file, which was Tim Van Holder's test case.
11979 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
11980 <sys/resource.h> can be included, include sys/time.h and
11981 sys/times.h first, if available. This works around the SunOS
11982 4.1.4 porting bug reported by Bruce Becker in
11983 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
11985 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
11986 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
11987 AC_HEADER_SYS_WAIT.
11989 Merge changes from gnulib. This was prompted because the CVS
11990 snapshot didn't build on Solaris 7 due to strnlen problems.
11992 These changes need to be merged back into gnulib:
11993 * lib/hash.c: Include <stdbool.h> unconditionally.
11994 * m4/onceonly.m4 (m4_quote): New macro.
11995 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
11996 Quote AC_FOREACH variable-expansions properly.
11997 The 2003-01-03 obstack.h change also needs merging.
11998 {end of changes requiring merging}
12000 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
12001 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,

12004 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
12005 New files, imported from gnulib.
12006 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
12009 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
12010 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
12013 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
12015 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
12016 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
12017 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
12018 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
12019 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
12020 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
12021 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
12022 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
12023 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
12024 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
12025 (jm_PREREQ_ARGMATCH): Remove.
12026 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
12027 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
12029 * src/system.h: Include <stdbool.h> unconditionally.
12031 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
12032 assuming at least C89 in the bitset code for some time now.
12034 2003-03-03 Akim Demaille <akim@epita.fr>
12038 2003-03-02 Akim Demaille <akim@epita.fr>
12040 * doc/bison.texinfo (Table of Symbols): Reactivate the
12041 documentation for %lex-param, and %parse-param.
12043 2003-03-02 Akim Demaille <akim@epita.fr>
12045 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
12046 generate verbose error messages.
12047 Use the number of tokens as an upper bound in yytname, as it
12048 cannot be a non terminal.
12050 2003-03-02 Akim Demaille <akim@epita.fr>
12052 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
12055 2003-03-02 Akim Demaille <akim@epita.fr>
12057 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
12058 Use them to exercise yycheck overrun.
12059 Based on Andrew Suffield's grammar.
12061 2003-03-02 Akim Demaille <akim@epita.fr>
12063 Create tests/local.at for Bison generic testing macros.
12065 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
12066 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
12068 * tests/calc.at (AT_CHECK_CALC): Adjust.
12069 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
12070 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
12071 * tests/local.at: here.
12072 (AT_COMPILE_CXX): Tags the tests using it as c++.
12073 Ignore the test if CXX is not functional.
12075 2003-03-01 Paul Eggert <eggert@twinsun.com>
12077 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
12078 not loc->end, since loc->end might contain garbage and this leads
12079 to undefined behavior on some platforms.
12080 (id_loc, token_start): Use (IF_LINTed) initial values that do not
12081 depend on *loc, so that the reader doesn't give the the false
12082 impression that *loc is initialized.
12083 (<INITIAL>"%%"): Do not bother setting code_start, since its value
12084 does not survive the return.
12086 2003-03-01 Akim Demaille <akim@epita.fr>
12088 * src/scan-gram.l (code_start): Always initialize it when entering
12089 into yylex, as SC_EPILOGUE is activated *before* the corresponding
12090 yylex invocation. An alternative would be making it static, but
12091 then it starts with the second %%'s beginning, instead of its end.
12093 2003-02-28 Paul Eggert <eggert@twinsun.com>
12095 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
12096 around a UnixWare 7.1.1 porting bug reported by John Hughes in
12097 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
12099 2003-02-26 Paul Eggert <eggert@twinsun.com>
12101 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
12102 Remove Sequent/Pyramid discussion (nobody uses them any more).
12103 Merge VMS and MS-DOS discussion; these ports may well be dead
12104 but let's keep mentioning them for now. Put <> around email
12105 addresses. Add copyright notice.
12107 2003-02-24 Paul Eggert <eggert@twinsun.com>
12109 * data/glr.c (yy_reduce_print): yylineno -> yylno,
12110 to avoid collision with flex use of yylineno.
12111 Problem reported by Bruce Lilly in
12112 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

12120 * data/lalr1.cc: Use temporary variables instead of casts to
12121 change integer types.
12122 Suggested by Paul Eggert.
12124 2003-02-21 Akim Demaille <akim@epita.fr>
12126 * doc/bison.texinfo: Use "location" consistently to refer to @n,
12127 to avoid confusions with lalr1.cc's notion of Position.
12128 Suggested by Paul Eggert.
12130 2003-02-20 Akim Demaille <akim@epita.fr>
12132 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
12133 before initial_columns.
12134 (location.hh): Use consistent variable names when defining the
12136 Use "last" so that we subtract from Positions, not from unsigned.
12138 2003-02-20 Akim Demaille <akim@epita.fr>
12140 * data/lalr1.cc (position.hh): New subfile, including the extended
12141 and Doxygen'ed documentation of class Position.
12142 (location.hh): Use it.
12143 Document a` la Doxygen.

12153 Don't use the location in yy::Parser::error_ and
12154 yy::Parser::print_ when not %locations.
12155 Activate more lalr1.cc tests.
12157 2003-02-19 Akim Demaille <akim@epita.fr>
12159 * data/lalr1.cc: When displaying a line number, be sure to make it
12162 2003-02-19 Akim Demaille <akim@epita.fr>
12164 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
12166 (YYABORT, YYACCEPT, YYERROR): New.
12167 * tests/calc.at: Renable the lalr1.cc test.
12169 2003-02-19 Akim Demaille <akim@epita.fr>
12171 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
12172 error recovery, mixing with/without pops and discarding of the
12175 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
12177 2003-02-17 Paul Eggert <eggert@twinsun.com>
12179 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
12180 * tests/testsuite.at (AT_COMPILE): Use them.
12181 This fixes the testsuite problem reported by Robert Lentz in
12182 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
12184 2003-02-12 Paul Eggert <eggert@twinsun.com>
12186 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
12187 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
12188 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
12189 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
12190 Check for malloc failure, for consistency with yacc.c.
12191 (yytname_size): Remove, for consistency with yacc.c.
12193 The bug still remains in data/lalr1.cc, as I didn't have time
12196 2003-02-06 Akim Demaille <akim@epita.fr>
12198 * configure.ac (GXX): Rename as...
12199 (CXX): this, to keep the original Autoconf semantics.
12201 * data/lalr1.cc: Fix b4_copyright invocations.
12202 If YYDEBUG is not defined, don't depend upon name_ being defined.
12203 (location.hh): Include string and iostream.
12204 (Position::filename): New member.
12205 (Position::Position ()): New.
12206 (operator<< (Position)): New.
12207 (operator- (Position, int)): New.
12208 (Location::first, Location::last): Rename as...
12209 (Location::begin, Location::end): these, to mock the conventional
12211 (operator<< (Location)): New.
12212 * tests/atlocal.in (CXX): New.
12213 * tests/testsuite.at (AT_COMPILE_CXX): New.
12214 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
12215 locations in a more synthetic way.
12216 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
12218 Adjust the C locations to match those from Emacs: first column is
12220 Change all the expected results.
12221 Conform to the GCS: simplify the locations when applicable.
12222 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
12223 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
12224 these CPP macros with the m4 macros new defined by...
12225 (AT_CHECK_PUSHDEFS): this, i.e.:
12226 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
12227 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
12229 (AT_CHECK_POPDEFS): Undefine them.
12230 (AT_CHECK_CALC_LALR1_CC): New.
12231 Use it for the first lalr1.cc test.
12233 2003-02-04 Akim Demaille <akim@epita.fr>
12235 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
12236 Location as is defined.
12238 2003-02-04 Akim Demaille <akim@epita.fr>
12240 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
12241 name_ being defined.
12243 2003-02-03 Paul Eggert <eggert@twinsun.com>
12245 * src/gram.h (start_symbol): Remove unused decl.
12247 Use more-consistent naming conventions for local vars.
12249 * src/derives.c (derives_compute): Change type of local var from
12250 int to rule_number.
12251 * src/gram.c (grammar_rules_partial_print): Likewise.
12252 * src/print.c (print_core): Likewise.
12253 * src/reduce.c (reduce_grammar_tables): Likewise.
12255 * src/gram.c (grammar_dump): Change name of item_number *
12256 local var from r to rp.
12257 * src/nullable.c (nullable_compute): Likewise.
12259 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
12261 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
12262 for symbol or symbol_number var.
12263 * src/reader.c (grammar_start_symbol_set): Likewise.
12264 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
12266 * src/state.c (transitions_to): Likewise.
12267 * src/state.h: Likewise.
12268 * src/tables.c (symbol_number_to_vector_number): Likewise.
12270 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
12273 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
12276 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
12279 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
12280 Use str, not s, for char * var. Use ch, not c, for character var.
12281 Use size for size var.
12283 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
12285 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
12287 * src/uniqstr.h: Likewise.
12289 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
12290 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
12291 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
12292 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
12293 param to have same name as that of enum, so that we don't use
12294 "s" to stand for a non-state.
12296 2003-02-02 Akim Demaille <akim@epita.fr>
12298 * src/scan-skel.l: Scan more than one inert character per yylex
12301 2003-02-01 Paul Eggert <eggert@twinsun.com>
12305 * po/LINGUAS: Add ms.
12307 2003-01-30 Akim Demaille <akim@epita.fr>
12309 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
12311 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12313 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
12316 Changes in response to error report by S. Eken: GLR mode does not
12317 handle negative $ indices or $ indices in embedded rules correctly.
12318 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
12320 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
12321 (b4_rhs_location): Ditto.
12322 (yyfill): New function to copy from stack tree into array
12324 (yyuserAction): Modify to allow incremental move of semantic values
12325 to rhs array when in GLR mode.
12326 Define YYFILL to use in user-defined actions to fill semantic array
12328 Remove dummy use of yystack, as there is now a guaranteed use.
12329 (yydoAction): Modify to allow incremental move of semantic values
12330 to rhs array when in GLR mode.
12331 (yyresolveAction): Ditto.
12332 (yyglrShiftDefer): Update comment.
12333 (yyresolveStates): Use X == NULL for pointers, not !X.
12334 (yyglrReduce): Ditto.
12335 (yydoAction): Ditto
12337 * tests/glr-regr1.at: Rename to ...
12338 * tests/glr-regression.at: Add new regression test for the problems
12339 described above (adapted from S. Eken).
12340 Update copyright notice.
12341 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
12342 * tests/Makefile.am: Ditto.
12344 2003-01-28 Paul Eggert <eggert@twinsun.com>
12346 * data/lalr1.cc: Do not use @output_header_name@ unless
12347 b4_defines_flag is set. This fixes two bugs reported by
12349 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
12350 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
12352 2003-01-21 Paul Eggert <eggert@twinsun.com>
12354 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
12355 we don't need to worry about yyerrlab1 being reported as an
12356 "unused label" by non-GCC C compilers. The downside is that if
12357 locations are used then a couple of statements are duplicated each
12358 time YYERROR is invoked, but the upside is that the warnings
12360 (yyerrlab1): Move code to YERROR.
12361 (yyerrlab2): Remove. Change uses back to yyerrlab1.
12362 This reverts some of the 2002-12-27 change.
12364 2003-01-17 Paul Eggert <eggert@twinsun.com>
12366 * src/output.c (symbol_printers_output): Fix typo that led
12367 to core dump. Problem reported by Antonio Rus in
12368 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
12370 2003-01-13 Akim Demaille <akim@epita.fr>,
12371 Quoc Peyrot <chojin@lrde.epita.fr>,
12372 Robert Anisko <anisko_r@lrde.epita.fr>
12374 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
12375 when the stacks contain one element, as the loop would otherwise
12376 free the last state, and then use the top state (the one we just
12377 popped). This means that the initial elements will not be freed
12378 explicitly, as is the case in yacc.c; it is not a problem, as
12379 these elements have fake values.
12381 2003-01-11 Paul Eggert <eggert@twinsun.com>
12383 * NEWS: %expect-violations are now just warnings, reverting
12384 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
12385 bootstrapping problem reported by Matthias Klose; see
12386 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
12387 * src/conflicts.c (conflicts_print): Likewise.
12388 * tests/conflicts.at (%expect not enough, %expect too much,
12389 %expect with reduce conflicts): Likewise.
12390 * doc/bison.texinfo (Expect Decl): Document this. Also mention
12391 that the warning is enabled if the number of conflicts changes
12392 (not necessarily increases).
12394 * src/getargs.c (version): Update copyright year.
12396 2003-01-09 Akim Demaille <akim@epita.fr>
12398 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
12400 2003-01-08 Paul Eggert <eggert@twinsun.com>
12402 * Makefile.maint (WGETFLAGS):
12403 New macro, containing "-C off" to disable proxy caches.
12404 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
12405 (rel-check): Use $(WGET) instead of wget.
12407 2003-01-06 Paul Eggert <eggert@twinsun.com>
12409 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
12410 the GLR paper of Scott, Johnstone and Hussain.
12412 2003-01-04 Paul Eggert <eggert@twinsun.com>
12414 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
12415 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
12416 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
12417 (EXTRA_LIBRARIES): New var, for liby.a.
12418 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
12419 (EXTRA_SCRIPTS): New var, for yacc.
12421 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
12422 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
12423 Problem reported by Nelson H. F. Beebe.
12425 2003-01-03 Paul Eggert <eggert@twinsun.com>
12427 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
12428 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
12429 when compiling Bison 1.875's `bitset bset = obstack_alloc
12430 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
12432 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
12433 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
12434 grow to a huge size with typical invocation.
12436 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
12437 Use the pattern recommended by Autoconf 2.57, except also protect
12438 against double-definition.
12439 * src/system.h: Likewise.
12440 Portability issues reported by Nelson H. F. Beebe.
12442 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
12443 All uses changed. Provide a definition in both C and C++.
12444 (yytrue, yyfalse): Define even if defined (__cplusplus).
12446 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
12447 Reported by Nelson H. F. Beebe.
12449 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
12451 2003-01-02 Paul Eggert <eggert@twinsun.com>
12453 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
12454 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
12455 Bug reported by Nelson H. F. Beebe.
12457 2003-01-01 Paul Eggert <eggert@twinsun.com>
12461 2002-12-30 Paul Eggert <eggert@twinsun.com>
12463 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
12465 (<INITIAL>","): Here. This causes stray "," to be treated
12468 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
12469 last brace in braced code when not in Yacc mode, for compatibility
12470 with Bison 1.35. This resurrects the 2001-12-15 patch to
12473 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
12474 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
12476 2002-12-28 Paul Eggert <eggert@twinsun.com>
12478 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
12479 that of SYM's type. This fixes Debian bug 168069, reported by
12482 2002-12-28 Paul Eggert <eggert@twinsun.com>
12486 Switch back to the Yacc style of conflict reports, undoing some
12487 of the 2002-07-30 change.
12488 * doc/bison.texinfo (Understanding): Use Yacc style for
12489 conflict reports. Also, use new way of locating rules.
12490 * src/conflicts.c (conflict_report):
12491 Renamed from conflict_report_yacc, removing the old
12492 'conflict_report'. Translate the entire conflict report at once,
12493 so that we don't assume that "," has the same interpretation in
12495 (conflicts_output): Use Yacc-style conflict report for each state,
12496 instead of our more-complicated style.
12497 (conflicts_print): Use Yacc-style conflict report, except print
12498 the input file name when not emulating Yacc.
12499 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
12500 Conflicted Reduction, %expect not enough, %expect too much,
12501 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
12502 * tests/existing.at (GNU Cim Grammar): Likewise.
12503 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
12505 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
12506 fatal): Don't invoke fflush; it's not needed and it might even be
12507 harmful for stdout, as stdout might not be open.
12508 * src/reduce.c (reduce_print): Likewise.
12510 2002-12-27 Paul Eggert <eggert@twinsun.com>
12512 Fix a bug where error locations were not being recorded correctly.
12513 This problem was originally reported by Paul Hilfinger in
12514 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
12516 * data/yacc.c (yyparse): New local var yylerrsp, to record the
12517 top of the location stack's error locations.
12518 (yyerrlab): Set it. When discarding a token, push its location
12519 onto yylerrsp so that we don't lose track of the error's end.
12520 (yyerrlab1): Now is only the target of YYERROR, so that we can
12521 properly record the location of the action that failed. For GCC
12522 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
12523 GCC warning about yyerrlab1 being unused if YYERROR is unused.
12524 (yyerrlab2): New label, which yyerrlab now falls through to.
12525 Compute the error's location by applying YYLLOC_DEFAULT to
12526 the locations of all the symbols that went into the error.
12527 * doc/bison.texinfo (Location Default Action): Mention that
12528 YYLLOC_DEFAULT is also invoked for syntax errors.
12529 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
12530 Error locations include the locations of all the tokens that were
12531 discarded, not just the last token.
12533 2002-12-26 Paul Eggert <eggert@twinsun.com>
12535 * src/files.c: Include quote.h.
12536 (compute_output_file_names): Warn if we detect conflicting
12537 outputs to the same file. This should catch the misunderstanding
12538 exemplified by Debian Bug 165349, reported by Bruce Stephens..
12540 * src/conflicts.c (conflicts_print): If the user specifies
12541 "%expect N", report an error if there are any reduce/reduce
12542 conflicts. This is what the manual says should happen.
12543 This fixes Debian bug 130890, reported by Anthony DeRobertis.
12544 * tests/conflicts.at (%expect with reduce conflicts): New test.
12546 Don't use m4_include on relative file names, as it doesn't work as
12547 desired if there happens to be a file with that name under ".".
12549 * m4sugar/version.m4: Remove; it was included but it wasn't used.
12550 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
12551 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
12552 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
12553 * src/output.c (output_skeleton): Use full path names when
12554 specifying a file to include; don't rely on include path, as
12555 it's unreliable when the working file contains a file with
12558 2002-12-25 Paul Eggert <eggert@twinsun.com>
12560 Remove obsolete references to bison.simple and bison.hairy.
12561 Problem mentioned by Aubin Mahe in
12562 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
12563 * data/glr.c: Comment fix.
12564 * doc/bison.1: Remove references. Also, mention "yacc".
12566 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
12569 * src/parse-gram.y (declaration): Use enum "report_states" rather
12570 than its numeric value 1.
12572 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
12573 opening a new one. This fixes Debian bug 165349, reported by
12576 2002-12-24 Paul Eggert <eggert@twinsun.com>
12580 * Makefile.maint (cvs-update): Don't assume that the shell
12581 supports $(...), as Solaris sh doesn't.
12583 * src/parse-gram.y (lloc_default): Remove test for empty
12584 nonterminals at the end, since it didn't change the result.
12586 2002-12-24 Paul Eggert <eggert@twinsun.com>
12588 If the user does not define YYSTYPE as a macro, Bison now declares it
12589 using typedef instead of defining it as a macro. POSIX requires this.
12590 For consistency, YYLTYPE is also declared instead of defined.
12592 %union directives can now have a tag before the `{', e.g., the
12593 directive `%union foo {...}' now generates the C code
12594 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12595 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12596 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12597 instead of `yyltype'.
12599 `yystype' and `yyltype' are now obsolescent macros instead of being
12600 typedefs or tags; they are no longer documented and will be
12601 withdrawn in a future release.
12603 * data/glr.c (b4_location_type): Remove.
12604 (YYSTYPE): Renamed from yystype.
12605 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
12606 (struct YYLTYPE): Renamed from struct yyltype.
12607 (YYLTYPE): Renamed from yyltype.
12608 (yyltype, yystype): New (and obsolescent) macros,
12609 for backward compatibility.
12610 * data/yacc.c: Likewise.
12612 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
12613 does not specify a union tag. This is for compatibility with
12616 * src/parse-gram.y (add_param): 2nd arg is now char * not char
12617 const *, since it is now modified by stripping surrounding { }.
12618 (current_braced_code): Remove.
12619 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
12620 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
12621 trailing " {...}". Now of type <chars>.
12622 (grammar_declaration): Adjust to bundled tokens.
12623 (code_content): Remove; stripping is now done by add_param.
12624 (print_token_value): Print contents of bundled tokens.
12625 (token_name): New function.
12627 * src/reader.h (braced_code, current_braced_code): Remove.
12628 (token_name): New decl.
12630 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
12631 token_type, not braced_code code_kind. All uses changed.
12632 (SC_PRE_CODE): New state, for scanning after a keyword that
12633 has (or usually has) an immediately-following braced code.
12634 (token_type): New local var, to keep track of which token type
12635 to return when scanning braced code.
12636 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
12637 <INITIAL>"%parse-param", <INITIAL>"%printer",
12638 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
12639 instead of returning a token type immediately.
12640 (<INITIAL>"{"): Set token type.
12641 (<SC_BRACED_CODE>"}"): Use it.
12642 (handle_action_dollar, handle_action_at): Now returns bool
12643 indicating success. Fail if ! current_rule; this prevents a core dump.
12644 (handle_symbol_code_dollar, handle_symbol_code_at):
12645 Remove; merge body into caller.
12646 (handle_dollar, handle_at): Complain in invalid contexts.
12648 * NEWS, doc/bison.texinfo: Document the above.
12649 * NEWS: Fix years and program names in copyright notice.
12651 2002-12-17 Paul Eggert <eggert@twinsun.com>
12653 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
12654 Reporting, Table of Symbols): Omit mentions of %lex-param and
12655 %parse-param from the documentation for now.
12657 2002-12-15 Paul Eggert <eggert@twinsun.com>
12659 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
12660 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
12661 lookahead symbol, and which sets yychar in parser actions) and it
12662 disagreed with the Bison documentation. Bug
12663 reported by Andrew Walrond.
12665 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
12666 as the caller now does that.
12667 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
12668 (YYEMPTY): Parenthesize right hand side, since others use it.
12669 (yyparse): Don't assume that our generated code is the only code
12672 2002-12-13 Paul Eggert <eggert@twinsun.com>
12676 POSIX requires a "yacc" command.
12677 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
12678 (MOSTLYCLEANFILES): Add yacc.
12680 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
12681 as an alias for bison y.
12683 * po/LINGUAS: Add da.
12685 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
12686 problem with latest <getopt.h>.
12687 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
12689 * doc/fdl.texi: Upgrade to 1.2.
12690 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
12691 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
12692 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
12694 * config/install-sh: Sync with autotools.
12696 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
12697 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12698 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
12699 locations are requested.
12700 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
12701 locations are requested.
12703 2002-12-12 Paul Eggert <eggert@twinsun.com>
12705 Remove unportable casts and storage allocation tricks.
12706 While we're at it, remove almost all casts, since they
12707 usually aren't needed and are a sign of trouble.
12709 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
12711 * src/derives.c (derives_compute): Do not subtract NTOKENS from
12712 the pointer DSET returned by malloc; this isn't portable.
12713 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
12714 Similarly for DERIVES.
12715 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
12716 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
12717 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
12719 * src/derives.c (derives_compute): Do not bother invoking
12720 int_of_rule_number, since rule numbers are integers.
12722 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
12723 rather than XMALLOC (char, N).
12725 * src/files.c (filename_split): Rewrite to avoid cast.
12727 * src/gram.h (symbol_number_as_item_number,
12728 item_number_as_symbol_number, rule_number_as_item_number,

12730 Now inline functions rather than macros, to avoid casts.
12731 * src/state.h (state_number_as_int): Likewise.
12732 * src/tables.c (state_number_to_vector_number,
12733 symbol_number_to_vector_number): Likewise.
12735 * src/gram.h (int_of_rule_number): Remove; no longer used.
12737 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
12738 since the resulting storage is always stored into.
12740 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
12743 * src/muscle_tab.c (muscle_m4_output):
12744 Now inline. Return bool, not int.
12745 * src/state.c (state_compare): Likewise.
12746 * src/symtab.c (symbol_check_defined,
12747 symbol_check_alias_consistency, symbol_pack, symbol_translation,

12755 symbol_check_alias_consistency_processor, symbol_pack_processor,
12756 symbol_translation_processor, hash_symbol_comparator,
12757 hash_symbol_hasher): Likewise.
12758 * src/uniqstr.c (uniqstr_print_processor): Likewise.
12759 * src/muscle_tab.c (muscles_m4_output):
12760 Use new functions instead of casting old functions unportably.
12761 * src/state.c (state_hash_new): Likewise.
12762 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
12763 symbols_token_translations_init):
12765 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
12767 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
12768 var instead of casting to long, to avoid casts.
12769 (prepare_states): Use MALLOC rather than alloca, so that we don't
12770 have to worry about alloca.
12771 * src/state.c (state_hash_lookup): Likewise.
12773 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
12774 local var instead of casting to unsigned char, to avoid casts.
12776 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
12777 STATE_ALLOC): Remove.
12778 (transitions_new, errs_new, reductions_new, state_new): Use malloc
12779 rather than calloc, and use offsetof to avoid allocating slightly
12781 (state_new): Initialize all members.
12783 * src/state.c (state_hash): Use unsigned accumulator, not signed.
12785 * src/symtab.c (symbol_free): Remove; unused.
12786 (symbol_get): Remove cast in lhs of assignment.
12787 (symbols_do): Now static. Accept generic arguments, not
12788 hashing-related ones.
12790 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
12791 (symbol_processor): Remove.
12792 (symbols_do): Remove decl; now static.
12794 * src/system.h (alloca): Remove; decl no longer needed.
12795 (<stddef.h>): Include, for offsetof.
12796 (<inttypes.>, <stdint.h>): Include if available.
12797 (uintptr_t): New type, if system lacks it.
12798 (CALLOC, MALLOC, REALLOC): New macros.
12799 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
12802 * src/tables.c (table_size): Now int, to pacify GCC.
12803 (table_grow, table_ninf_remap): Use signed table size.

12813 * src/getargs.c (getargs): Don't assume EOF == -1.
12815 2002-12-09 Paul Eggert <eggert@twinsun.com>
12817 Change identifier spellings to avoid collisions with names
12818 that are reserved by POSIX.
12820 Don't use names ending in _t, since POSIX reserves them.
12821 For consistency, remove _e and _s endings -- they're weren't
12822 needed to remove ambiguity. All uses changed.
12823 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
12824 turn was just renamed from struniq_t.
12825 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
12826 which in turn was just renamed from struniq_processor_t.
12827 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
12828 in turn was renamed from hash_compare_struniq_t.

12898 value_t_as_yystype -> value_as_yystype.
12900 Don't include <errno.h> in the mainstream code, since it
12901 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
12902 * lib/get-errno.c, lib/get-errno.h: New files.
12903 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
12905 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
12906 * src/output.c (output_skeleton): Likewise.

12913 (TAB_EXT): Renamed from EXT_TAB.
12914 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
12916 Avoid str[a-z]*, since <string.h> reserves that name space.
12917 Change all instances of "struniq" in names to "uniqstr", and
12918 likewise for "STRUNIQ" and "UNIQSTR".
12919 * src/uniqstr.c: Renamed from src/struniq.c.
12920 * src/uniqstr.h: Renamed from src/struniq.h.

12931 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
12932 (N_EXPAND): Renamed from N_STRETCH.

12940 * src/symtab.h (SYMBOL_NUMBER_MAXIMUM): Renamed from SYMBOL_NUMBER_MAX.
12941 * src/tables.c (VECTOR_NUMBER_MAX, VECTOR_NUMBER_MIN): Remove; unused.
12942 (BASE_MAXIMUM): Renamed from BASE_MAX.
12943 (BASE_MINIMUM): Renamed from BASE_MIN.
12944 (ACTION_MAX): Remove; unused.
12945 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
12946 Unnecessary casts removed from above defines.
12949 Fix misspelling in names.
12950 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
12951 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
12955 * lib/timevar.c (timevar_report): Renamed from time_report,
12956 for consistency with other names.
12957 * lib/timevar.h (timevar_report): New decl.
12958 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
12961 Sort include-file uses.
12963 Reorder all include files under src to be in the order "system.h".
12964 then the ../lib include files in angle brackets (alphabetized),
12965 then the . include files in double-quotes (alphabetized). Fix
12966 dependency breakages encountered in this process, as follows:
12967 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
12968 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
12969 * src/state.h: Include "symtab.h".
12971 2002-12-08 Paul Eggert <eggert@twinsun.com>
12973 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
12974 since this causes problems when __file__ contains character
12975 sequences like "@" that are treated specially by src/scan-skel.l.
12976 Instead, just use the file's basename. This fixes the bug
12977 reported by Martin Mokrejs in
12978 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
12980 2002-12-06 Paul Eggert <eggert@twinsun.com>
12982 Add support for rules that do not have trailing semicolons, as
12983 POSIX requires. Improve the quality of locations in Bison
12986 * src/location.c: Include <quotearg.h>.
12987 (empty_location): Now const.
12988 (location_print): New function. Follow the recommendation of the
12989 GNU Coding Standards for locations that span file boundaries.
12990 * src/location.h: Do not include <quotearg.h>; no longer needed.
12991 (boundary): New type.
12992 (location_t): Use it. This allows locations to span file boundaries.
12993 All member uses changed: file -> start.file or end.file (as needed),
12994 first_line -> start.line, first_column -> start.column,
12995 last_line -> end.line, last_column -> end.column.
12996 (equal_boundaries): New function.
12997 (LOCATION_RESET, LOCATION_STEP): Remove.
12998 (LOCATION_PRINT): Remove. All callers changed to use location_print.
12999 (empty_location): Now const.
13000 (location_print): New decl.
13001 * src/parse-gram.y (lloc_default): New function, which handles
13002 empty locations more accurately.
13003 (YYLLOC_DEFAULT): Use it.
13004 (%token COLON): Remove.
13005 (%token ID_COLON): New token.
13007 (declarations, rules): Remove trailing semicolon.
13008 (declaration, rules_or_grammar_declaration):
13009 Allow empty (";") declaration.
13010 (symbol_def): Remove empty actions; no longer needed.
13011 (rules_or_grammar_declaration): Remove trailing semicolon.
13012 (semi_colon.opt): Remove.
13013 * src/reader.h: Include location.h.
13014 (scanner_cursor): New decl.
13015 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
13017 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
13019 (STEP): Remove. No longer needed, now that adjust_location does
13020 the work. All uses removed.
13021 (scanner_cursor): New var.
13022 (adjust_location): Renamed from extend_location. It now sets
13023 *loc and adjusts the scanner cursor. All uses changed.
13024 Don't bother testing for CR.
13025 (handle_syncline): Remove location arg; now updates scanner cursor.
13026 All callers changed.
13027 (unexpected_end_of_file): Now accepts start boundary of token or
13028 comment, not location. All callers changed. Update scanner cursor,
13030 (SC_AFTER_IDENTIFIER): New state.
13031 (context_state): Renamed from c_context. All uses changed.
13032 (id_loc, code_start, token_start): New local vars.
13033 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
13034 processing of Yacc white space and equivalents here.
13035 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
13036 instead of returning ID immediately, since we need to search for
13037 a subsequent colon.
13038 (<INITIAL>"'", "\""): Save token_start.
13039 (<INITIAL>"%{", "{", "%%"): Save code_start.
13040 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
13041 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
13042 BEGIN context_state at end, not INITIAL.
13043 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
13044 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
13045 Return correct token start.
13046 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
13047 the start of a character, string or multiline comment is found.
13048 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
13049 Reduction): Adjust reported locations to match the more-precise
13050 results now expected.
13051 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
13052 * tests/reduce.at (Useless Rules, Reduced Automaton,
13053 Underivable Rules): Likewise.
13054 * tests/regression.at (Invalid inputs): No longer `expecting ";"
13055 or "|"' now that so many other tokens are allowed by the new grammar.
13057 * src/complain.h (current_file): Remove duplicate decl;
13058 current_file is now owned by files.h.
13059 * src/complain.c, src/scan-gram.l: Include files.h.
13061 2002-12-06 Paul Eggert <eggert@twinsun.com>
13063 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
13064 promotes to int; it might be unsigned int.
13065 * data/yacc.c (yy_reduce_print): Likewise.
13067 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
13068 be #defined in the prologue, not in the Bison declarations.
13069 This fixes Debian Bug 102878, reported by Shaul Karl.
13071 2002-12-02 Paul Eggert <eggert@twinsun.com>
13073 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
13074 * lib/strtoul.c: New file, from gnulib.
13075 This fixes a porting bug reported by Peter Klein in
13076 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
13078 2002-11-30 Paul Eggert <eggert@twinsun.com>
13080 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
13081 and put only a forward declaration in the prologue. This is for
13082 consistency with the other scanner helper functions.
13084 Type clashes now generate warnings, not errors, since it
13085 appears that POSIX may allow some grammars with type clashes.
13086 * src/reader.c (grammar_current_rule_check): Warn about
13087 type clashes instead of complaining.
13088 * tests/input.at (Type Clashes): Expect warnings, not complaints.
13090 Add Yacc library, since POSIX requires it.
13091 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
13092 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
13093 * lib/main.c, lib/yyerror.c: New files.
13095 gram_error can be static; it need not be extern.
13096 * src/reader.h (gram_error): Remove decl.
13097 * src/parse-gram.y (gram_error): Now static. Add static decl.
13098 (print_token_value): Omit parameter names from forward decl,
13101 2002-11-29 Paul Eggert <eggert@twinsun.com>
13103 * doc/bison.texinfo: Emphasize that yylex and yyerror must
13104 be declared before being used. E.g., one should typically
13105 declare them in the prologue. Use GNU coding style in examples.
13106 Put "const" consistently after the type it modifies. Mention
13107 that C99 supports "inline". Mention that yyerror traditionally
13110 %parse-param and %lex-param now take just one argument, the
13111 declaration; the argument name is deduced from the declaration.
13113 * doc/bison.texinfo (Parser Function, Pure Calling, Error
13114 Reporting, Table of Symbols): Document this.
13115 * src/parse-gram.y (add_param): New function.
13117 (declaration): Implement new rule for %parse-param and %lex-param.
13118 * src/scan-gram.l: "," now elicits a warning, rather than being
13119 a token; this is more compatible with byacc.
13120 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
13122 2002-11-27 Paul Eggert <eggert@twinsun.com>
13124 Rename identifiers to avoid real and potential collisions.
13126 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
13127 to avoid collision with lex macro described by Bruce Lilly in
13128 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
13129 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
13130 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
13131 * src/parse-gram.y (print_token_value): Renamed from yyprint.
13133 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
13134 The name "yycontrol" violates the name space rules, and this stuff
13135 wasn't being used anyway.
13136 (input): Remove action; this stuff wasn't being used.
13137 (gram_error): Rename local variable yylloc -> loc.
13138 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
13139 (YY_DECL): Don't use "yy" at start of local variables.
13140 All uses changed, e.g., yylloc -> loc.
13141 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
13142 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
13143 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
13144 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
13146 * src/parse-gram.y (gram_error): loc is now const *.
13147 * src/reader.h (gram_error): Likewise.
13149 2002-11-24 Paul Eggert <eggert@twinsun.com>
13153 * tests/actions.at (Actions after errors): Use an output format
13154 more similar to that of the Printers and Destructors test.
13155 Test the position of the ';' token too.
13156 (Printers and Destructors): Likewise.
13157 (Printers and Destructors: %glr-parser): Remove for now, to avoid
13158 unnecessarily alarming people when the test fails.
13160 * data/yacc.c (yyerrlab1): Move this label down, so that the
13161 parser does not discard the lookahead token if the user code
13162 invokes YYERROR. This change is required for POSIX conformance.
13164 * lib/error.c: Sync with gnulib.
13166 2002-11-22 Paul Eggert <eggert@twinsun.com>
13168 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
13169 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
13170 * lib/xmalloc.c: Likewise.
13172 2002-11-20 Paul Eggert <eggert@twinsun.com>
13174 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
13176 2002-11-20 Paul Eggert <eggert@twinsun.com>
13178 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
13179 should use `if (! x) abort ();' rather than `assert (x);', and
13180 anyway it's one less thing to worry about configuring.
13182 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
13183 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
13184 and replace all instances of assert with abort.
13185 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
13186 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
13188 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
13189 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
13190 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
13191 hash_find_entry, hash_rehash, hash_insert): Likewise.
13192 * src/conflicts.c (resolve_sr_conflict): Likewise.
13193 * src/lalr.c (set_goto_map, map_goto): Likewise.
13194 * src/nullable.c (nullable_compute): Likewise.
13195 * src/output.c (prepare_rules, token_definitions_output): Likewise.
13196 * src/reader.c (packgram, reader): Likewise.
13197 * src/state.c (state_new, state_free, state_transitions_set,
13198 state_reduction_find): Likewise.
13199 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
13200 symbol_pack): Likewise.
13201 * src/tables.c (conflict_row, pack_vector): Likewise.
13202 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
13203 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
13204 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
13205 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
13207 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
13208 (ARGMATCH_CONSTRAINT): New macro.
13209 (ARGMATCH_ASSERT): Use it.
13211 * src/system.h (verify): New macro.
13212 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
13213 rather than assert.
13214 * src/tables.c (tables_generate): Likewise.
13216 * src/struniq.c (struniq_assert): Now returns void, and aborts
13217 if the assertion is false.
13218 (struniq_assert_p): Remove.
13219 * src/struniq.h: Likewise.
13221 2002-11-18 Paul Eggert <eggert@twinsun.com>
13223 * data/glr.c (yygetLRActions): Replace `yyindex' with
13224 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
13225 This fixes the regression with Sun ONE Studio 7 cc that I reported in
13226 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
13228 2002-11-18 Akim Demaille <akim@epita.fr>
13230 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
13232 From Tim Van Holder.
13234 2002-11-17 Paul Eggert <eggert@twinsun.com>
13236 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
13237 to "SyntaxError" for consistency with my 2002-11-15 change.
13239 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
13240 not define to {}, since this breaks the common use of `YYDPRINTF
13241 ((...));' if a single statement is desired (e.g. before `else').
13242 Work around GCC warnings by surrounding corresponding calls with
13244 (yyhasResolvedValue): Remove unused function.
13245 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
13247 (yyreportSyntaxError): Renamed from yyreportParseError.
13248 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
13250 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
13251 extern when possible. Remove unused initializations.
13253 2002-11-16 Akim Demaille <akim@epita.fr>
13255 Augment the similarity between GLR and LALR traces.
13257 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
13258 (YY_REDUCE_PRINT): New.
13259 (yyparse): Use them.
13260 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
13262 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
13263 state reached after the reduction/recovery, since...
13264 (yyparse, yyprocessOneStack): Report the state we are entering in.
13266 2002-11-16 Akim Demaille <akim@epita.fr>
13268 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
13269 Add support for --trace=skeleton.
13270 * src/scan-skel.l: %option debug.
13271 Scan strings of non-@ or \n instead of character by character.
13272 (scan_skel): Handle trace_skeleton.
13274 (@output_parser_name@, @output_header_name@): ``Restore'' their
13275 support (used to be M4 macros).
13276 * data/yacc.c: Quote larger chunks, a la glr.c.
13277 * data/lalr1.cc: Likewise.
13278 The header guards are no longer available, so use some other
13279 string than `YYLSP_NEEDED'.
13281 2002-11-16 Akim Demaille <akim@epita.fr>
13283 Make the ``Printers and Destructors'' test more verbose, taking
13284 `yacc.c''s behavior as (possibly wrong) reference.
13286 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
13287 instead of fprint on stdout.
13288 Set and report the last_line of the symbols.
13289 Consistently display values and locations.
13291 2002-11-16 Paul Eggert <eggert@twinsun.com>
13293 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
13295 2002-11-15 Paul Eggert <eggert@twinsun.com>
13297 * tests/actions.at (Actions after errors): New test case.
13299 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
13300 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
13301 tests/action.at, tests/calc.at, tests/conflicts.at,
13302 tests/cxx-type.at, tests/regression.at:
13303 "parse error" -> "syntax error" for POSIX compatibility.
13304 "parsing stack overflow..." -> "parser stack overflow" so
13305 that code matches Bison documentation.
13307 2002-11-15 Akim Demaille <akim@epita.fr>
13309 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
13310 take two BRACED_CODE, not two string_content.
13311 Free the scanner's obstack when we are done.
13312 (code_content): New.
13313 * tests/calc.at: Adjust.
13314 * doc/bison.texinfo: Adjust.
13315 Also, make sure to include the `,' for these declarations.
13317 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
13319 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
13320 definition; avoids potential autoreconf problems.
13322 2002-11-15 Akim Demaille <akim@epita.fr>
13324 Always check the value returned by yyparse.
13326 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
13327 returned by yyparse.
13328 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
13330 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
13331 returned by yyparse.
13333 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13335 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
13338 2002-11-14 Paul Eggert <eggert@twinsun.com>
13340 * src/output.c (output_skeleton): Call xfopen instead of
13341 duplicating xfopen's body.
13343 Fix bugs reported by Nelson H. F. Beebe in
13344 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
13346 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
13347 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
13348 Group compiler. Instead, use "$CC -E bar.c". Include the .h
13349 file twice in the grammar, as an extra check.
13351 * tests/input.at (Torturing the Scanner): Surround the
13352 backslash-newline tests with "#if 0", to make it less likely that
13353 we'll run into compiler bugs. Bring back solitary \ inside
13354 comment, but add a closing comment to work around HP C bug. Don't
13355 test backslash-newline in C character constant.
13357 2002-11-14 Akim Demaille <akim@epita.fr>
13359 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
13360 status of the compiler.
13361 Calling `exit 1' is no longer needed.
13362 Reported by Nelson H. F. Beebe.
13364 2002-11-14 Akim Demaille <akim@epita.fr>
13366 * tests/atlocal.in (CPPFLAGS): We have config.h.
13367 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
13369 * tests/actions.at, tests/calc.at, tests/conflicts.at,
13370 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
13371 * tests/regression.at, tests/torture.at: Use them for all the
13372 grammars that are to be compiled.
13373 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
13374 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
13375 * doc/bison.texinfo (GLR Parsers): Document `inline'.
13377 2002-11-14 Akim Demaille <akim@epita.fr>
13379 * doc/bison.texinfo: Various formatting changes (alignments in
13380 samples, additional @group/@end group, GCS in samples.
13381 Use @deffn instead of simple @table to define the directives,
13382 macros, variables etc.
13384 2002-11-13 Paul Eggert <eggert@twinsun.com>
13386 Fix some bugs reported by Albert Chin-A-Young in
13387 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
13389 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
13390 -o c"; the HP C compiler chatters during compilation.
13391 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
13392 * tests/headers.at (export YYLTYPE): Likewise.
13394 * tests/input.at (Torturing the Scanner): Remove lines containing
13395 solitary backslashes, as they tickle a bug in the HP C compiler.
13397 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
13398 comments, since they're not portable. Use GNU coding style.
13400 2002-11-13 Akim Demaille <akim@epita.fr>
13402 * data/yacc.c: Leave bigger chunks of quoted text.
13403 (YYDSYMPRINTF): New.
13404 Use it to report symbol activities.
13405 * data/glr.c (YYDSYMPRINTF): New.
13408 2002-11-12 Paul Eggert <eggert@twinsun.com>
13412 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
13413 (yyglrReduce): Return yyok, not 0.
13414 This should avoid the enumerated-type warnings reported
13415 by Nelson H. F. Beebe in
13416 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
13418 * lib/bbitset.h (BITSET_INLINE): Remove.
13419 * lib/bitset.h [! BITSET_INLINE]: Remove.
13420 (bitset_set, bitset_reset, bitset_test): Rename local vars
13421 to avoid shadowing warnings by GCC.
13423 * data/glr.c (inline): Remove #define. It's the user's
13424 responsibility to #define it away, just like 'const'.
13425 This fixes one of the bugs reported by Nelson H. F. Beebe in
13426 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
13428 * Makefile.maint (po-check): Scan .l and .y files instead of the
13429 .c and the .h files that they generate. This fixes the bug
13430 reported by Tim Van Holder in:
13431 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
13432 Look for N_ as well as for _. Try to avoid matching #define for
13434 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
13435 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
13436 * src/scan-gram.l: Revamp regular expressions so that " and '
13437 do not confuse xgettext.
13439 * src/struniq.h (struniq_new): Do not declare the return type
13440 to be 'const'; this violates the C standard.

13589 Revamp to fix many (but not all) of the C- and M4-related quoting
13590 problems. Among other things, this fixes the Bison bug reported
13591 by Jan Hubicka when processing the Bash grammar; see:
13592 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
13594 Use new @ escapes consistently. Represent brackets with @{ and @}
13595 rather than @<:@ and @:>@, since this works a bit better with dumb
13596 editors like vi. Represent @ with @@, since @ is now consistently
13597 an escape. Use @oline@ and @ofile@ rather than __oline__ and
13598 __ofile__, to avoid unexpected expansions. Similarly, use @output
13599 rather than #output.
13601 * data/c.m4 (b4_copyright): Omit file name from comment, since
13602 the file name could contain "*/".
13603 (b4_synclines_flag): Don't quote the 2nd argument; it should already
13604 be quoted. All uses changed.
13606 * data/glr.c: Use new @ escapes consistently.
13607 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
13608 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
13609 Remove, since they couldn't handle arbitrary characters in file
13611 * data/lalr1.cc: Likewise.
13612 * data/yacc.c: Likewise.
13614 * src/files.c (output_infix): Remove; all uses removed.
13615 * src/files.h: Likewise.
13617 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
13618 mishandled funny characters in file names, and anyway it isn't
13620 * data/yacc.c: Likewise.
13621 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
13623 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
13624 * data/yacc.c: Likewise.
13626 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
13628 (muscle_init): Quote filename as a C string.

13630 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
13631 * src/output.c (escaped_file_name_output): New function.
13632 (prepare_symbols): Quote tokens for M4.
13633 (prepare): Don't insert output_infix, output_prefix,
13634 output_parser_name, output_header_name; this is now down by scan-skel.
13635 Insert skeleton as a C string.
13637 * src/output.c (user_actions_output, symbol_destructors_output,
13638 symbol_printers_output): Quote filenames for C and M4.
13639 * src/reader.c (prologue_augment, epilogue_set): Likewise.
13641 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
13642 escapes other than \\ and \'; this simplifies the code.
13643 (<SC_STRING>): Likewise, for \\ and \".
13644 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
13645 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
13646 Use new escapes @{ and @} for [ and ].
13648 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
13649 them with auto vars.
13650 Switch to new escape scheme, where @ is the escape character uniformly.
13651 Abort if a stray escape character is found. Avoid unbounded input
13652 buffer when parsing non-escaped text.
13654 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
13655 __oline__, #output, $@, and @{ do not have unintended meanings.
13657 2002-11-09 Paul Eggert <eggert@twinsun.com>
13659 Fix the test failure due to GCC warnings described in
13660 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
13661 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
13662 evaluate to 0 if it's impossible for NINF to be in the respective
13664 (yygetLRActions, yyrecoverParseError): Use them.
13666 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
13667 counted in the token inserted at end of file. Now takes
13668 location_t *, not location_t, so that the location can be
13669 adjusted. All uses changed.
13671 * tests/regression.at (Invalid inputs): Adjust wording in
13672 diagnostic to match the new behavior.
13674 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
13675 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
13676 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
13677 abort ();'. This reduces the runtime of the "Many lookaheads"
13678 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
13681 2002-11-07 Paul Eggert <eggert@twinsun.com>
13683 * src/parse-gram.y (CHARACTER): Remove unused token.
13686 * src/scan-gram.l: Remove stack option. We no longer use the
13687 stack, since the stack was never deeper than 1; instead, use the
13688 new auto var c_context to record the stacked value.
13690 Remove nounput option. At an unexpected end of file, we now unput
13691 the minimal input necessary to end cleanly; this simplifies the
13694 Avoid unbounded token sizes where this is easy.
13696 (unexpected_end_of_file): New function.
13697 Use it to systematize the error message on unexpected EOF.
13698 (last-string): Now auto, not static.

13702 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
13703 not the (never otherwised-used) CHARACTER.
13705 2002-11-07 Akim Demaille <akim@epita.fr>

13909 (Symbols): Document that trigraphs have no special meaning in Bison,
13910 nor is backslash-newline allowed.
13911 (Actions): Document that trigraphs have no special meaning.
13913 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
13916 2002-11-02 Paul Eggert <eggert@twinsun.com>
13918 * src/reader.c: Don't include quote.h; not needed.
13919 (get_merge_function): Reword warning to be consistent with
13920 type clash diagnostic in grammar_current_rule_check.
13922 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
13923 bug in trigraph handling.
13925 * src/output.c (prepare_symbols): When printing token names,
13926 escape "[" as "@<:@" and likewise for "]".
13928 * src/system.h (errno): Remove declaration, as we are now
13929 assuming C89 or better, and C89 guarantees errno.
13931 2002-10-30 Paul Eggert <eggert@twinsun.com>
13933 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
13934 Check for close failures.
13935 * src/files.h (xfclose): Return void, not int, since it always
13937 * src/files.c (xfclose): Likewise. Report I/O error if ferror
13939 * src/output.c (output_skeleton): Use xfclose rather than fclose
13940 and ferror. xfclose now checks ferror.
13942 * data/glr.c (YYLEFTMOST_STATE): Remove.
13943 (yyreportTree): Use a stack-based leftmost state. This avoids
13944 our continuing battles with bogus warnings about initializers.
13946 2002-10-30 Akim Demaille <akim@epita.fr>
13948 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
13951 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13953 * tests/glr-regr1.at: New test for reported regressions.
13954 * tests/testsuite.at: Add glr-regr1.at test.
13955 * tests/Makefile.am: Add glr-regr1.at test.
13957 2002-10-24 Paul Eggert <eggert@twinsun.com>
13961 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
13962 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
13963 we use malloc. Don't assume 'A' through 'Z' are contiguous.
13964 Don't assume strdup exists; POSIX says its an XSI extension.
13965 Check for buffer overflow on input.
13967 2002-10-24 Akim Demaille <akim@epita.fr>
13969 * src/output.c (output_skeleton): Don't disable M4sugar comments
13970 too soon: it results in comments being expanded.
13971 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
13974 2002-10-24 Akim Demaille <akim@epita.fr>
13976 * data/yacc.c (m4_int_type): New.
13977 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
13978 char' as only yacc.c wants K&R portability.
13979 * data/glr.c (yysigned_char): Remove.
13980 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
13981 Reported by Quoc Peyrot.
13983 2002-10-23 Paul Eggert <eggert@twinsun.com>
13985 * src/main.c (main): With --trace=time, report times even if a
13986 non-fatal error occurs. Formerly, the times were reported in some
13987 such cases but not in others.
13988 * src/reader.c (reader): Just return if a complaint has been issued,
13989 instead of exiting, so that 'main' can report times.
13991 2002-10-22 Akim Demaille <akim@epita.fr>
13993 * src/system.h: Include sys/types.
13994 Reported by Bert Deknuydt.
13996 2002-10-23 Paul Eggert <eggert@twinsun.com>
13998 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
13999 Suggested by Art Haas.
14001 2002-10-22 Paul Eggert <eggert@twinsun.com>
14003 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
14004 decl; not needed any more.
14005 * src/main.c (main): Use return to exit, undoing yesterday's change.
14006 The last OS that we could find where this wouldn't work is
14007 SunOS 3.5, and that's too old to worry about now.
14009 * data/glr.c (struct yyltype): Define members even when not
14010 doing locations. This is more consistent with yacc.c, and it
14011 works around the following bug reports:
14012 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
14013 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
14015 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
14016 @acronym consistently. Standardize on "Yacc" instead of "YACC",
14017 "Algol" instead of "ALGOL". Give a bit more history about BNF.
14019 2002-10-22 Akim Demaille <akim@epita.fr>
14021 * data/README: New.
14023 2002-10-21 Paul Eggert <eggert@twinsun.com>
14025 Be consistent about 'bool'; the old code used an enum in one
14026 module and an int in another, and this violates the C standard.
14027 * m4/stdbool.m4: New file, from coreutils 4.5.3.
14028 * configure.ac (AC_HEADER_STDBOOL): Add.
14029 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
14030 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
14031 * src/symtab.c (hash_compare_symbol_t): Likewise.
14032 * src/system.h (bool, false, true): Use a definition consistent
14033 with ../lib/hash.c. All uses changed.
14035 * src/complain.c (warning_issued): Renamed from warn_message_count,
14036 so that we needn't worry about integer overflow (!).
14037 Now of type bool. All uses changed.
14038 (complaint_issued): Renamed from complain_message_count; likewise.
14040 * src/main.c (main): Use exit to exit with failure.
14042 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
14043 rather than 1 and 0.
14044 * src/main.c (main): Likewise.
14045 * src/getargs.c (getargs): Likewise.
14046 * src/reader.c (reader): Likewise.
14048 * src/getarg.c (getargs): Remove duplicate code for
14049 "Try `bison --help'".
14051 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
14052 What was that "2" for?
14054 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
14055 * src/getargs.c (usage): Likewise.
14057 * src/getargs.c (getargs): When there are too few operands, report
14058 the last one. When there are too many, report the first extra
14059 one. This is how diffutils does it.
14061 2002-10-20 Paul Eggert <eggert@twinsun.com>
14063 Remove K&R vestiges.
14064 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
14065 * src/complain.c (VA_START): Remove. Assume prototypes.
14066 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
14067 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
14068 fatal): Assume prototypes.
14069 * src/complain.h: Assume prototypes.
14070 * src/system.h (PARAMS): Remove.
14071 Include <limits.h> unconditionally, since it's guaranteeed even
14072 for a freestanding C89 compiler.
14073 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
14074 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
14076 2002-10-20 Akim Demaille <akim@epita.fr>
14078 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
14079 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
14080 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
14081 (yyresolveStates, yyresolveAction, yyresolveStack)
14082 (yyprocessOneStack): Use them.
14083 (yy_reduce_print): New.
14084 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
14086 2002-10-20 Akim Demaille <akim@epita.fr>
14088 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
14089 arguments and output `void'.
14090 (b4_c_function): Rename as...
14091 (b4_c_function_def): this.
14092 (b4_c_function_decl, b4_c_ansi_function_def)
14093 (b4_c_ansi_function_decl): New.
14094 Change the interpretation of the arguments: before `int, foo', now
14096 * data/yacc.c (yyparse): Prototype and define thanks to these.
14097 Adjust b4_c_function_def uses.
14098 * data/glr.c (yyparse): Likewise, but ANSI only.
14100 2002-10-20 Akim Demaille <akim@epita.fr>
14102 * src/output.c (prepare): Move the definition of `tokens_number',
14103 `nterms_number', `undef_token_number', `user_token_number_max'
14105 (prepare_tokens): Here.
14106 (prepare_tokens): Rename as...
14107 (prepare_symbols): this.
14108 (prepare): Move the definition of `rules_number' to...
14109 (prepare_rules): here.
14110 (prepare): Move the definition of `last', `final_state_number',
14111 `states_number' to...
14112 (prepare_states): here.
14113 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
14115 2002-10-20 Akim Demaille <akim@epita.fr>
14117 * src/tables.h, src/tables.c, src/output.c: Comment changes.
14119 2002-10-20 Akim Demaille <akim@epita.fr>
14121 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
14124 2002-10-20 Akim Demaille <akim@epita.fr>
14126 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
14127 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
14129 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
14131 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
14132 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
14135 2002-10-19 Paul Eggert <eggert@twinsun.com>
14137 Do not create a temporary file, as that involves security and
14138 cleanup headaches. Instead, use a pair of pipes.
14139 Derived from a suggestion by Florian Krohm.
14140 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
14141 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
14142 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
14143 (BISON_PREREQ_SUBPIPE): Add.
14144 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
14145 Add subpipe.h, subpipe.c.
14146 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
14147 * po/POTFILES.in: Add lib/subpipe.c.
14148 * src/output.c: Include "subpipe.h".
14149 (m4_invoke): Remove decl.
14150 (scan_skel): New decl.
14151 (output_skeleton): Use pipe rather than temporary file for m4 input.
14152 Check that m4sugar.m4 is readable, to avoid deadlock.
14153 Check for pipe I/O error.
14154 * src/scan-skel.l (readpipe): Remove decl.
14155 (scan_skel): New function, to be used in place of m4_invoke.
14156 Read from stream rather than file.
14158 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
14159 float, as this generates a warning on Solaris 8 + GCC 3.2 with
14160 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
14161 this generates a more-accurate value anyway.
14163 * lib/timevar.c (timervar_accumulate): Rename locals to
14164 avoid confusion with similarly-named more-global.
14165 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
14167 * src/output.c (prepare): Use xstrdup to convert char const *
14168 to char *, to avoid GCC warning.
14170 2002-10-19 Akim Demaille <akim@epita.fr>
14172 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
14173 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
14174 Use them to have `calc.y' ready for %pure-parser.
14175 * data/yacc.c (YYLEX): Pass a yylex return type to
14176 b4_c_function_call.
14178 2002-10-19 Akim Demaille <akim@epita.fr>
14180 Prototype support of %lex-param and %parse-param.
14182 * src/parse-gram.y: Add the definition of the %lex-param and
14183 %parse-param tokens, plus their rules.
14184 Drop the `_' version of %glr-parser.
14186 * src/scan-gram.l (INITIAL): Scan them.
14187 * src/muscle_tab.c: Comment changes.
14188 (muscle_insert, muscle_find): Rename `pair' as `probe'.
14189 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
14190 (muscle_entry_s): The `value' member is no longer const.
14191 Adjust all dependencies.
14192 * src/muscle_tab.c (muscle_init): Adjust: use
14193 MUSCLE_INSERT_STRING.
14194 Initialize the obstack earlier.
14195 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
14196 (muscle_pair_list_grow): New.
14197 * data/c.m4 (b4_c_function_call, b4_c_args): New.
14198 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
14199 * tests/calc.at: Use %locations, not --locations.
14200 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
14202 2002-10-19 Akim Demaille <akim@epita.fr>
14204 * src/getargs.c (usage): Take status as argument and exit
14206 Report the traditional `Try ... --help' message when status != 0.
14207 (usage, version): Don't take a FILE * as arg, it is pointless.
14208 (getargs): When there is an incorrect number of arguments, make it
14209 an error, and report it GNUlically thanks to `usage ()'.
14211 2002-10-18 Paul Eggert <eggert@twinsun.com>
14213 * data/glr.c (yyreportParseError): Don't assume that sprintf
14214 yields the length of the printed string, as this is not true
14215 on SunOS 4.1.4. Reported by Peter Klein.
14217 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
14218 * tests/conflicts.at (%nonassoc and eof): Likewise.
14219 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
14221 2002-10-17 Akim Demaille <akim@epita.fr>
14223 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
14224 * src/getargs.c (trace_types, trace_args): Adjust.
14225 * src/reader.c (grammar_current_rule_prec_set)
14226 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
14227 Standardize error messages.
14228 And s/@prec/%prec/!
14229 (reader): Use trace_flag to enable scanner/parser debugging,
14230 instead of an adhoc scheme.
14231 * src/scan-gram.l: Remove trailing debugging code.
14233 2002-10-16 Paul Eggert <eggert@twinsun.com>
14235 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
14238 * NEWS: Officially drop support for building Bison with K&R C,
14239 since it didn't work anyway and it's not worth worrying about.
14240 * Makefile.maint (wget_files): Remove ansi2knr.c.
14241 (ansi2knr.c-url_prefix): Remove.
14242 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
14243 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
14244 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
14246 2002-10-15 Paul Eggert <eggert@twinsun.com>
14248 Stop using the "enum_" trick for K&R-style function definitions;
14249 it confused me, and I was the author! Instead, assume that people
14250 who want to use K&R C compilers (when using these modules in GCC,
14251 perhaps?) will run ansi2knr.
14253 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
14254 All uses of "enum_" changed to "enum ".
14255 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

14266 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
14267 Use function prototypes; this removes the need for declaring
14268 static functions simply to provide their prototypes.

14343 tests/cxx-type.at, tests/headers.at, tests/input.at,
14344 tests/regression.at, tests/synclines.at, tests/torture.at:
14345 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
14346 so that the tests still work even if POSIXLY_CORRECT is set.
14347 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
14349 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
14350 for portability to K&R hosts. Fix typo: signed char is guaranteed
14351 only to 127, not to 128.
14352 * data/glr.c (yysigned_char): New type.
14353 * data/yacc.c (yysigned_char): Likewise.
14354 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
14356 2002-10-13 Paul Eggert <eggert@twinsun.com>
14358 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
14359 true due to limited range of data type" warning from GCC.
14361 * data/c.m4 (b4_token_defines): Protect against double-inclusion
14362 by wrapping enum yytokentype's definition inside #ifndef
14363 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
14365 2002-10-13 Akim Demaille <akim@epita.fr>
14367 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
14368 Un yy- yyrhs to avoid the name clash with the global YYRHS.
14370 2002-10-13 Akim Demaille <akim@epita.fr>
14372 * Makefile.maint: Update from Autoconf 2.54.
14373 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
14375 2002-10-13 Akim Demaille <akim@epita.fr>
14377 * src/print.c (print_state): Separate the list of solved conflicts
14378 from the other items.
14379 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
14381 2002-10-13 Akim Demaille <akim@epita.fr>
14383 Let nondeterministic skeletons be usable with deterministic
14386 With the patch, GAWK compiled by GCC without -O2 passes its test
14387 suite using a GLR parser driven by LALR tables. It fails with -O2
14388 because `struct stat' gives two different answers on my machine:
14389 88 (definition of an auto var) and later 96 (memset on this var).
14390 Hence the stack is badly corrumpted. The headers inclusion is to
14391 blame: if I move the awk.h inclusion before GLR's system header
14392 inclusion, the two struct stat have the same size.
14394 * src/tables.c (pack_table): Always create conflict_table.
14395 (token_actions): Always create conflict_list.
14396 * data/glr.c (YYFLAG): Remove, unused.
14398 2002-10-13 Akim Demaille <akim@epita.fr>
14400 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
14402 (VALGRIND, GXX): New.
14403 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
14404 * tests/bison.in: Run $PREBISON a pre-command.

14411 * data/glr.c: Formatting changes.
14412 Tweak some trace messages to match yacc.c's.
14414 2002-10-13 Akim Demaille <akim@epita.fr>
14416 GLR parsers sometimes raise parse errors instead of performing the
14418 Reported by Charles-Henry de Boysson.
14420 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
14421 check the length of the traces when %glr.
14422 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
14424 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
14426 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
14427 (yyltype): Remove the yy prefix from the member names.
14428 (yytable): Complete its comment.
14429 (yygetLRActions): Map error action number from YYTABLE from
14431 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
14432 (which was a bug: it should have been YYTABEL_NINF, and yet it was
14433 not satisfying as we could compare an YYACTION computed from
14434 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
14435 only value for error actions.
14436 (yyreportParseError): In verbose parse error messages, don't issue
14437 `error' in the list of expected tokens.
14438 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
14439 next action to perform to match glr.c's decoding.
14440 (yytable): Complete its comment.

14444 Fix problem reported by Henrik Grubbstroem in
14445 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
14446 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
14447 because the Bison parser reads the second action before reducing
14449 * src/scan-gram.l (rule_length): New static var.
14450 Use it to keep track of the rule length in the scanner, since
14451 we can't expect the parser to be in lock-step sync with the scanner.
14452 (handle_action_dollar, handle_action_at): Use this var.
14453 * tests/actions.at (Exotic Dollars): Test for the problem.
14455 2002-10-12 Paul Eggert <eggert@twinsun.com>
14457 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
14458 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
14459 Include <sys/time.h> when checking for clock_t and struct tms.
14460 Use same include order as source.
14461 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
14462 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
14464 * lib/timevar.c: Update copyright date and clarify comments.
14465 (get_time) [IN_GCC]: Keep the GCC version for reference.
14467 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
14468 GCC version as of today, then merge Bison's changes.
14469 Change "GCC" to "Bison" in copyright notice. timevar.def's
14470 author is Akim, so change that too.
14472 * src/reader.c (grammar_current_rule_check):
14473 Don't worry about the default action if $$ is untyped.
14474 Prevents bogus warnings reported by Jim Gifford in

14478 * data/glr.c, data/lalr1.cc, data/yacc.c:
14479 Output token definitions before the first part of user declarations.
14480 Fixes compatibility problem reported by Jim Gifford for kbd in

14485 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...

14503 Portability fixes for bitsets; this also avoids several GCC
14506 * lib/abitset.c: Include <stddef.h>, for offsetof.
14507 * lib/lbitset.c: Likewise.
14509 * lib/abitset.c (abitset_bytes): Return a size that is aligned
14510 properly for vectors of objects. Do not assume that adding a
14511 header size to a multiple of a word size yields a value that is
14512 properly aligned for the whole union.
14513 * lib/bitsetv.c (bitsetv_alloc): Likewise.
14515 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
14516 unique names for structures.

14548 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
14549 All instances of parameters of type enum bitset_opts are now of
14550 type enum_bitset_opts, to conform to the C Standard, and similarly
14551 for enum_bitset_type.
14552 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
14553 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
14555 Do not use "struct bitset_struct" to mean different things in
14556 different modules. Not only is this confusing, it violates
14557 the C Standard, which requires that structure types in different
14558 modules must be compatible if one is to be passed to the other.
14559 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
14560 All instances of "struct bitset_struct *" replaced with "bitset".

14571 bitset_struct): Remove.
14572 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
14575 Do not call a function of type T using a call that assumes the
14576 function is of a different type U. Standard C requires that a
14577 function must be called with a type that is compatible with its

14604 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
14605 the same width as int. This reapplies a hunk of the 2002-08-12 patch
14606 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
14607 which was inadvertently undone by the 2002-09-30 patch.

14609 the same width as int.
14611 2002-10-04 Paul Eggert <eggert@twinsun.com>
14615 * configure.ac (AC_INIT), NEWS: Increment version number.
14617 * doc/bison.texinfo: Minor spelling, grammar, and white space
14619 (Symbols): Mention that any negative value returned from yylex
14620 signifies end-of-input. Warn about negative chars. Mention
14621 the portable Standard C character set.
14623 The GNU coding standard says CFLAGS and YFLAGS are reserved
14624 for the installer to set.
14625 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
14626 * src/Makefile.am (AM_CFLAGS): Likewise.
14627 (AM_YFLAGS): Renamed from YFLAGS.

14636 POSIX 1003.1-2001 has removed fgrep.
14638 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>

14813 2002-09-06 Paul Eggert <eggert@twinsun.com>
14815 * doc/bison.texinfo (Conditions): Make explicit that the GPL
14816 exception applies only to yacc.c. This is a modification of a
14817 patch originally suggested by Akim Demaille.

14911 PROTOTYPES to check for prototypes, and "defined __STDC__" to

14917 (bitset_test): Now returns int, not unsigned long.

14961 to void, to avoid a GCC warning when --disable-nls is in effect.

14964 to minimize the number of warnings from xgettext.
14965 (handle_action_dollar, handle_action_at): Don't use isdigit,
14966 as it mishandles negative chars and it may not work as expected
14967 outside the C locale.
14969 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
14970 this is a GCC extension and is not portable to other compilers.

14977 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
14980 * tests/regression.at: Do not use 'cc -c input.c -o input';
14981 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
14983 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
14984 exit status as failure, not just exit status 1. Sun C exits
14985 with status 2 sometimes.
14987 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
14988 Use it for the two large tests.

15007 * tests/conflicts.at, tests/reduce.at: Adjust.

15152 different: save its reduction (accept) instead of having a state
15153 without any action (no shift or goto, no reduce).
15154 Note: the final state is now a ``regular'' state, i.e., the
15155 parsers now contain `reduce 0' as default reduction.
15156 Nevertheless, since they decide to `accept' when yystate =
15157 final_state, they still will not reduce rule 0.

15203 yycontrol without making too strong assumptions on the parser
15205 * src/output.c (prepare_tokens): Use the real 0th value of
15206 token_translations instead of `0'.

17581 (output_skeleton): Don't look for the skeleton location, let m4 do
17583 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
17585 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
17586 (prepare): Given that for the time being changesyntax is not
17587 usable in M4, rename the muscles using `-' to `_'.

17651 Suggested by Robert Anisko.
17653 2002-01-24 Akim Demaille <akim@epita.fr>
17655 Bison dumps core when trying to complain about broken input files.
17656 Reported by Cris van Pelt.
17658 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
17659 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
17661 (Invalid inputs): Strengthen: exercise parse_percent_token.
17663 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
17665 * src/Makefile.am: Add bison.c++.
17666 * src/bison.c++: New skeleton.
17668 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
17672 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
17674 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
17676 2002-01-20 Marc Autret <marc@gnu.org>
17678 * src/files.c (compute_output_file_names): Fix
17680 2002-01-20 Marc Autret <marc@gnu.org>
17682 * tests/output.at: New test.
17683 * src/files.c (compute_base_names): Don't map extensions when
17684 the YACC flag is set, use defaults.
17685 Reported by Evgeny Stambulchik.
17687 2002-01-20 Marc Autret <marc@gnu.org>
17689 * src/system.h: Need to define __attribute__ away for non-GCC
17690 compilers as well (i.e., the vendor C compiler).
17691 Suggested by Albert Chin-A-Young.
17693 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
17695 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
17696 canonical definition.
17697 * src/system.h: Use the canonical definition for PARAMS (avoids
17698 a conflict with the macro from lib/hash.h).
17700 2002-01-11 Akim Demaille <akim@epita.fr>
17702 * configure.in: Use AC_FUNC_STRNLEN.
17703 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
17705 2002-01-09 Akim Demaille <akim@epita.fr>
17707 * src/files.c, src/files.h (output_infix): New.
17708 (tab_extension): Remove.
17709 (compute_base_names): Compute the former, drop the latter.
17710 * src/output.c (prepare): Insert the muscles `output-infix', and
17712 * src/parse-skel.y (string, string.1): New.
17713 (section.header): Use it.
17714 (section.yacc): Remove.
17715 (prefix): Remove too.
17716 * src/scan-skel.l: Adjust.
17717 * src/bison.simple, src/bison.hairy: Adjust.
17719 2002-01-09 Akim Demaille <akim@epita.fr>
17721 * configure.in (WERROR_CFLAGS): Compute it.
17722 * src/Makefile.am (CFLAGS): Pass it.
17723 * tests/atlocal.in (CFLAGS): Idem.
17724 * src/files.c: Fix a few warnings.
17725 (get_extension_index): Remove, unused.
17727 2002-01-08 Akim Demaille <akim@epita.fr>
17729 * src/getargs.c (AS_FILE_NAME): New.
17730 (getargs): Use it to convert DOSish file names.
17731 * src/files.c (base_name): Rename as full_base_name to avoid
17732 clashes with `base_name ()'.
17733 (filename_split): New.
17734 (compute_base_names): N-th rewrite, using filename_split.
17736 2002-01-08 Akim Demaille <akim@epita.fr>
17738 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
17739 New, stolen from the Fileutils 4.1.
17740 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
17741 * configure.in: Check for the presence of memrchr, and of its
17744 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
17746 * lib/hash.h (__P): Added definition for this macro.
17747 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
17748 BUILT_SOURCES, to ensure they are generated first.
17749 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
17750 %error-verbose to allow bootstrapping with bison 1.30x.
17752 2002-01-06 Akim Demaille <akim@epita.fr>
17754 * src/reader.c (parse_braces): Don't fetch the next char, the
17755 convention is to fetch on entry.
17756 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
17757 'switch' without a following semicolon.
17758 * tests/regression.at (braces parsing): New.
17760 2002-01-06 Akim Demaille <akim@epita.fr>
17762 Bison is dead wrong in its RR conflict reports.
17764 * tests/torture.at (GNU Cim Grammar): New.
17765 * src/conflicts.c (count_rr_conflicts): Fix.
17767 2002-01-06 Akim Demaille <akim@epita.fr>
17769 Creating package.m4 from configure.ac causes too many problems.
17771 * tests/Makefile.am (package.m4): Create it by hand,
17772 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
17774 2002-01-06 Akim Demaille <akim@epita.fr>
17776 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
17779 2002-01-04 Paul Eggert <eggert@twinsun.com>
17781 * doc/bison.texinfo (Debugging):
17782 Remove YYSTDERR; it's no longer defined or used.
17783 Also, s/cstdio.h/cstdio/.
17785 2002-01-03 Akim Demaille <akim@epita.fr>
17787 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
17789 2002-01-03 Akim Demaille <akim@epita.fr>
17791 * src/parse-skel.y (process_skeleton): Don't bind the parser's
17792 tracing code to --trace, wait for a better --trace option, with
17795 2002-01-03 Akim Demaille <akim@epita.fr>
17797 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
17798 The ISO C++ standard is extremely clear about it: stderr is
17799 considered a macro, not a regular symbol (see table 94 `Header
17800 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
17801 Therefore std:: does not apply to it. It still does with fprintf.
17802 Also, s/cstdio.h/cstdio/.
17804 2002-01-03 Akim Demaille <akim@epita.fr>
17806 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
17807 for non system headers.
17809 2002-01-02 Akim Demaille <akim@epita.fr>
17811 Equip the skeleton chain with location tracking, runtime trace,
17812 pure parser and scanner.
17814 * src/parse-skel.y: Request a pure parser, locations, and prefix
17816 (%union): Having several members with the same type does not help
17817 type mismatches, simplify.
17818 (YYPRINT, yyprint): New.
17819 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
17820 (skel_error): this.
17822 * src/scan-skel.l: Adjust to these changes.
17823 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
17824 (LOCATION_PRINT, skel_control_t): New.
17826 2001-12-30 Akim Demaille <akim@epita.fr>
17828 * src/parse-skel.y: Get rid of the shift/reduce conflict:
17829 replace `gb' with BLANKS.
17830 * src/scan-skel.l: Adjust.
17832 2001-12-30 Akim Demaille <akim@epita.fr>
17834 * src/system.h: We don't need nor want bcopy.
17835 Throw away MS-DOS crap: we don't need getpid.
17836 * configure.in: We don't need strndup. It was even causing
17837 problems: because Flex includes the headers *before* us,
17838 _GNU_SOURCE is not defined by config.h, and therefore strndup was
17840 * lib/xstrndup.c: New.
17841 * src/scan-skel.l: Use it.
17842 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
17843 * src/parse-skel.y: Use %directives instead of #defines.
17845 2001-12-30 Akim Demaille <akim@epita.fr>
17847 * src/skeleton.h: New.
17848 * src/output.c (output_parser, output_master_parser): Remove, dead
17850 * src/output.h (get_lines_number, actions_output, guards_output)
17851 (token_definitions_output): Prototype them.
17852 * src/parse-skel.y: Add the license notice.
17853 Include output.h and skeleton.h.
17854 (process_skeleton): Returns void, and takes a single parameter.
17855 * src/scan-skel.l: Add the license notice.
17856 Include skeleton.h.
17857 Don't use %option yylineno: it seems that then Flex imagines
17858 REJECT has been used, and therefore it won't reallocate its
17859 buffers (which makes no other sense to me than a bug). It results
17860 in warnings for `unused: yy_flex_realloc'.
17862 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
17864 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17865 (MUSCLE_INSERT_PREFIX): ...to there.
17866 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17867 (MUSCLE_INSERT_PREFIX): Move from here...
17869 * src/bison.hairy: Add a section directive. Put braces around muscle
17870 names. This parser skeleton is still broken, but Bison should not
17871 choke on a bad muscle 'syntax'.
17872 * src/bison.simple: Add a section directive. Put braces around muscle
17875 * src/files.h (strsuffix, stringappend): Add declarations.
17876 (tab_extension): Add declaration.
17877 (short_base_name): Add declaration.
17879 * src/files.c (strsuffix, stringappend): No longer static. These
17880 functions are used in the skeleton parser.
17881 (tab_extension): New.
17882 (compute_base_names): Use the computations done in this function
17883 to guess if the generated parsers should have '.tab' in their
17885 (short_base_name): No longer static.
17887 * src/output.c (output_skeleton): New.
17888 (output): Disable call to output_master_parser, and give a try to
17889 a new skeleton handling system.
17890 (guards_output, actions_output): No longer static.
17891 (token_definitions_output, get_lines_number): No longer static.
17893 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
17895 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
17898 * src/parse-skel.y: New file.
17899 * src/scan-skel.l: New file.
17901 2001-12-29 Akim Demaille <akim@epita.fr>
17903 %name-prefix is broken.
17905 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
17906 Adjust all dependencies.
17907 * tests/headers.at (export YYLTYPE): Strengthen this test: use
17910 Renaming yylval but not yylloc is not consistent. Now we do.
17912 * src/bison.simple: Prefix yylloc if used.
17913 * doc/bison.texinfo (Decl Summary): Document that.
17915 2001-12-29 Akim Demaille <akim@epita.fr>
17917 * doc/bison.texinfo: Promote `%long-directive' over
17919 Remove all references to fixed-output-files, yacc is enough.
17921 2001-12-29 Akim Demaille <akim@epita.fr>
17923 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
17924 user prologue. These are defaults.
17925 * tests/actions.at (Mid-rule actions): Make sure the user can
17926 define YYDEBUG and YYERROR_VERBOSE.
17928 2001-12-29 Akim Demaille <akim@epita.fr>
17930 * src/output.c (header_output): Don't forget to export YYLTYPE and
17932 * tests/headers.at (export YYLTYPE): New, make sure it does.
17933 * tests/regression.at (%union and --defines, Invalid CPP headers):
17935 * tests/headers.at: here.
17937 2001-12-29 Akim Demaille <akim@epita.fr>
17939 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
17941 2001-12-29 Akim Demaille <akim@epita.fr>
17943 * tests/actions.at (Mid-rule actions): Output on a single line
17944 instead of several.
17946 2001-12-29 Akim Demaille <akim@epita.fr>
17948 * doc/bison.texinfo: Formatting changes.
17950 2001-12-29 Akim Demaille <akim@epita.fr>
17952 Don't store the token defs in a muscle, just be ready to output it
17953 on command. Now possible via `symbols'. Fixes a memory leak.
17955 * src/output.c (token_definitions_output): New.
17956 (output_parser, header_output): Use it.
17957 * src/reader.c (symbols_save): Remove.
17959 2001-12-29 Akim Demaille <akim@epita.fr>
17961 * src/bison.simple: Do not provide a default for YYSTYPE and
17962 YYLTYPE before the user's prologue. Otherwise it's hardly... a
17965 2001-12-29 Akim Demaille <akim@epita.fr>
17967 Mid-rule actions are simply... ignored!
17969 * src/reader.c (readgram): Be sure to attach mid-rule actions to
17970 the empty-rule associated to the dummy symbol, not to the host
17972 * tests/actions.at (Mid-rule actions): New.
17974 2001-12-29 Akim Demaille <akim@epita.fr>
17978 * src/reader.c (reader): Free grammar.
17980 2001-12-29 Akim Demaille <akim@epita.fr>
17984 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
17985 since it allocates it for each state, although only one is needed.
17986 (allocate_storage): Do it here.
17988 2001-12-29 Akim Demaille <akim@epita.fr>
17990 * src/options.h, src/options.c (create_long_option_table): Rename
17992 (long_option_table_new): this, with a clearer prototype.
17993 (percent_table): Remove, unused,
17994 * src/getargs.c (getargs): Adjust.
17996 2001-12-29 Akim Demaille <akim@epita.fr>
17998 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
17999 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
18002 2001-12-29 Akim Demaille <akim@epita.fr>
18004 * src/lalr.c (build_relations): Rename `states' as `states1'.
18005 Sorry, I don't understand exactly what it is, no better name...
18007 2001-12-29 Akim Demaille <akim@epita.fr>
18009 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
18010 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
18011 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
18014 2001-12-29 Akim Demaille <akim@epita.fr>
18016 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
18019 2001-12-29 Akim Demaille <akim@epita.fr>
18021 * src/reader.c, src/reader.h (user_toknums): Remove.
18022 Adjust all users to use symbols[i]->user_token_number.
18024 2001-12-29 Akim Demaille <akim@epita.fr>
18026 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
18027 Adjust all users to use symbols[i]->prec or ->assoc.
18029 2001-12-29 Akim Demaille <akim@epita.fr>
18031 * src/reader.c, src/reader.h (tags): Remove.
18032 Adjust all users to use symbols[i]->tag.
18034 2001-12-29 Akim Demaille <akim@epita.fr>
18036 * src/gram.h, src/gram.c (symbols): New, similar to state_table
18038 * src/reader.c (packsymbols): Fill this table.
18040 * src/conflicts.c (resolve_sr_conflict): Adjust.
18041 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
18043 Use symbols[i]->tag instead of tags[i].
18045 2001-12-29 Akim Demaille <akim@epita.fr>
18047 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
18048 In addition, put a comment in there, to replace...
18049 * tests/regression.at (%union and C comments): Remove.
18051 2001-12-29 Akim Demaille <akim@epita.fr>
18053 * tests/regression.at (Web2c Actions): Blindly move the actual
18054 output as expected output. The contents *seem* right to me, but I
18055 can't pretend reading perfectly parser tables... Nonetheless, all
18056 the other tests pass correctly, the table look OK, even though the
18057 presence of `$axiom' is to be noted: AFAICS it is useless (but
18060 2001-12-29 Akim Demaille <akim@epita.fr>
18062 * src/reader.c (readgram): Don't add the rule 0 if there were no
18063 rules read. In other words, add it _after_ having performed
18064 grammar sanity checks.
18065 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
18067 2001-12-29 Akim Demaille <akim@epita.fr>
18069 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
18070 visible, and some states have now a different number.
18072 2001-12-29 Akim Demaille <akim@epita.fr>
18074 * src/reader.c (readgram): Bind the initial rule's lineno to that
18076 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
18077 (Solved SR Conflicts): Adjust rule 0's line number.
18079 2001-12-29 Akim Demaille <akim@epita.fr>
18081 Fix the `GAWK Grammar' failure.
18083 * src/LR0.c (final_state): Initialize to -1 so that we do compute
18084 the reductions of the first state which was mistakenly confused
18085 with the final state because precisely final_state was initialized
18087 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
18088 now noticed by Bison.
18089 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
18090 have a reduction on $default.
18092 2001-12-29 Akim Demaille <akim@epita.fr>
18094 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
18096 * src/closure.c (print_closure): Likewise.
18097 * src/derives.c (print_derives): Likewise.
18098 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
18101 2001-12-29 Akim Demaille <akim@epita.fr>
18103 * src/lalr.c (lookaheads_print): New.
18104 (lalr): Call it when --trace-flag.
18105 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
18108 2001-12-29 Akim Demaille <akim@epita.fr>
18110 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
18111 when walking through ritem, even via rule->rhs.
18112 * src/reduce.c (dump_grammar, useful_production, reduce_output)
18113 (useful_production, useless_nonterminals): Likewise.
18114 (reduce_grammar_tables): Likewise, plus update nritems.
18115 * src/nullable.c (set_nullable): Likewise.
18116 * src/lalr.c (build_relations): Likewise.
18117 * tests/sets.at (Nullable): Adjust.
18118 Fortunately, now, the $axiom is no longer nullable.
18120 2001-12-29 Akim Demaille <akim@epita.fr>
18122 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
18124 * src/gram.c (ritem_longest_rhs): Likewise.
18125 * src/reduce.c (nonterminals_reduce): Likewise.
18126 * src/print_graph.c (print_graph): Likewise.
18127 * src/output.c (output_rule_data): Likewise.
18128 * src/nullable.c (set_nullable): Likewise.
18130 2001-12-29 Akim Demaille <akim@epita.fr>
18132 * src/output.c: Comment changes.
18134 2001-12-27 Paul Eggert <eggert@twinsun.com>
18136 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
18137 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
18138 Sparc, as they were causing more porting problems than the
18139 (minor) performance improvement was worth.
18141 Also, catch up with 1.31's YYSTD.
18143 2001-12-27 Akim Demaille <akim@epita.fr>
18145 * src/output.c (output_gram): Rely on nritems, not the
18146 0-sentinel. See below.
18147 Use -1 as separator, not 0.
18148 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
18149 Rely on -1 as separator in yyrhs, instead of 0.
18150 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
18151 twice `Now at end of input', therefore there are two lines less to
18154 2001-12-27 Akim Demaille <akim@epita.fr>
18156 * tests/regression.at (Unresolved SR Conflicts):
18157 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
18160 2001-12-27 Akim Demaille <akim@epita.fr>
18162 * src/LR0.c (new_state): Recognize the final state by the fact it
18163 is reached by eoftoken.
18164 (insert_start_shifting_state, insert_eof_shifting_state)
18165 (insert_accepting_state, augment_automaton): Remove, since now
18166 these states are automatically computed from the initial state.
18167 (generate_states): Adjust.
18168 * src/print.c: When reporting a rule number to the user, substract
18169 1, so that the axiom rule is rule 0, and the first user rule is 1.
18170 * src/reduce.c: Likewise.
18171 * src/print_graph.c (print_core): For the time being, just as for
18172 the report, depend upon --trace-flags to dump the full set of
18174 * src/reader.c (readgram): Once the grammar read, insert the rule
18175 0: `$axiom: START-SYMBOL $'.
18176 * tests/set.at: Adjust: rule 0 is now displayed, and since the
18177 number of the states has changed (the final state is no longer
18178 necessarily the last), catch up.
18180 2001-12-27 Akim Demaille <akim@epita.fr>
18182 Try to make the use of the eoftoken valid. Given that its value
18183 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
18184 is used instead of > 0 where appropriate, (ii), depend upon nritems
18185 instead of the 0-sentinel.
18187 * src/gram.h, src/gram.c (nritems): New.
18188 Expected to be duplication of nitems, but for the time being...
18189 * src/reader.c (packgram): Assert nritems and nitems are equal.
18190 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
18191 * src/closure.c (print_closure, print_fderives): Likewise.
18192 * src/gram.c (ritem_print): Likewise.
18193 * src/print.c (print_core, print_grammar): Likewise.
18194 * src/print_graph.c: Likewise.
18196 2001-12-27 Akim Demaille <akim@epita.fr>
18198 * src/main.c (main): If there are complains after grammar
18199 reductions, then output the report anyway if requested, then die.
18200 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
18201 * src/reader.c (eoftoken): New.
18202 (parse_token_decl): If the token being defined has value `0', it
18204 (packsymbols): No longer hack `tags' to insert `$' by hand.
18205 Be sure to preserve the value of the eoftoken.
18206 (reader): Make sure eoftoken is defined.
18207 Initialize nsyms to 0: now eoftoken is created just like the others.
18208 * src/print.c (print_grammar): Don't special case the eof token.
18209 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
18210 lie anyway, albeit pleasant.
18211 * tests/calc.at: Exercise error messages with eoftoken.
18212 Change the grammar so that empty input is invalid.
18213 Adjust expectations.
18214 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
18216 2001-12-27 Akim Demaille <akim@epita.fr>
18218 * configure.in: Check the protos of strchr ans strspn.
18219 Replace strchr if needed.
18220 * src/system.h: Provide the protos of strchr, strspn and memchr if
18222 * lib/strchr.c: New.
18223 * src/reader.c (symbols_save): Use strchr.
18225 2001-12-27 Akim Demaille <akim@epita.fr>
18227 * src/print.c, src/print_graph.c (escape): New.
18228 Use it to quote the TAGS outputs.
18229 * src/print_graph.c (print_state): Now errors are in red, and
18230 reductions in green.
18231 Prefer high to wide: output the state number on a line of its own.
18233 2001-12-27 Akim Demaille <akim@epita.fr>
18235 * src/state.h, src/state.c (reductions_new): New.
18236 * src/LR0.c (set_state_table): Let all the states have a
18237 `reductions', even if reduced to 0.
18238 (save_reductions): Adjust.
18239 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.

18256 2001-12-27 Akim Demaille <akim@epita.fr>
18258 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
18259 * src/print.c: here.
18260 (lookaheadset, shiftset): New, used as additional storage by
18262 (print_results): Adjust.
18263 (print_shifts, print_gotos, print_errs): New, extracted from...
18264 (print_actions): here.
18265 * src/print_graph.c (print_actions): Remove dead code.
18267 2001-12-27 Akim Demaille <akim@epita.fr>
18269 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
18272 2001-12-27 Akim Demaille <akim@epita.fr>
18274 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
18275 (build_relations): Adjust.
18277 2001-12-27 Akim Demaille <akim@epita.fr>
18279 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
18282 2001-12-27 Akim Demaille <akim@epita.fr>
18284 * src/reader.c (packgram): Catch nitems overflows.
18286 2001-12-27 Akim Demaille <akim@epita.fr>
18288 * src/files.c, src/files.h (guard_obstack): Remove.
18289 * src/output.c (output): Adjust.
18290 * src/reader.c (parse_braces): New, factoring...
18291 (copy_action, copy_guard): these two which are renamed as...
18292 (parse_action, parse_guard): these.
18293 As a voluntary consequence, using braces around guards is now
18296 2001-12-27 Akim Demaille <akim@epita.fr>
18298 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
18299 * src/reader.c (symbol_list): `guard' and `guard_line' are new
18301 (symbol_list_new): Adjust.
18302 (copy_action): action_line is the first line, not the last.
18303 (copy_guard): Just as for actions, store the `action' only, not
18304 the switch/case/break flesh.
18305 Don't parse the user action that might follow the guard, let...
18306 (readgram): do it, i.e., now, there can be an action after a
18308 In other words the guard is just explicitly optional.
18309 (packgram): Adjust.
18310 * src/output.c (guards_output): New.
18311 (output_parser): Call it when needed.
18312 (output): Also free the guard and attrs obstacks.
18313 * src/files.c, src/files.h (obstack_save): Remove.
18314 (output_files): Remove.
18315 As a result, if one needs the former `.act' file, using an
18316 appropriate skeleton which requires actions and guards is now
18318 * src/main.c (main): Adjust.
18319 * tests/semantic.at: New.
18320 * tests/regression.at: Use `input.y' as input file name.
18321 Avoid 8+3 problems by requiring input.c when the test needs the
18324 2001-12-27 Akim Demaille <akim@epita.fr>
18326 * src/reader.c (symbol_list_new): Be sure to initialize all the
18329 2001-12-27 Akim Demaille <akim@epita.fr>
18331 All the hacks using a final pseudo state are now useless.
18333 * src/LR0.c (set_state_table): state_table holds exactly nstates.
18334 * src/lalr.c (nLA): New.
18335 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
18336 instead of lookaheadsp from the pseudo state (nstate + 1).
18338 2001-12-27 Akim Demaille <akim@epita.fr>
18340 * src/output.c (action_row, token_actions): Use a state_t instead
18341 of a integer, and nlookaheads instead of the following state's

18348 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
18349 (conflicts_print, print_reductions): Use a state_t instead of an
18350 integer when referring to a state.
18351 As much as possible, depend upon nlookaheads, instead of the
18352 `lookaheadsp' member of the following state (since lookaheads of
18353 successive states are successive, the difference between state n + 1
18354 and n served as the number of lookaheads for state n).
18355 * src/lalr.c (add_lookback_edge): Likewise.
18356 * src/print.c (print_core, print_actions, print_state)
18357 (print_results): Likewise.
18358 * src/print_graph.c (print_core, print_actions, print_state)

18367 Add plenty of `static'.
18369 2001-12-27 Akim Demaille <akim@epita.fr>
18371 * src/output.c (prepare): Drop the muscle `ntbase' which
18372 duplicates ntokens.
18373 * src/bison.simple: Formatting/comment changes.
18374 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
18375 is an undocumented synonym.
18377 2001-12-22 Akim Demaille <akim@epita.fr>
18379 * src/output.c (output_table_data): Change the prototype to use
18380 `int' for array ranges: some invocations do pass an int, not a
18382 Reported by Wayne Green.
18384 2001-12-22 Akim Demaille <akim@epita.fr>
18386 Some actions of web2c.y are improperly triggered.
18387 Reported by Mike Castle.
18389 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
18390 * tests/regression.at (Web2c): Rename as...
18391 (Web2c Report): this.
18392 (Web2c Actions): New.
18394 2001-12-22 Akim Demaille <akim@epita.fr>
18396 Reductions in web2c.y are improperly reported.
18397 Reported by Mike Castle.
18399 * src/conflicts.c (print_reductions): Fix.
18400 * tests/regression.at (Web2c): New.
18402 2001-12-18 Akim Demaille <akim@epita.fr>
18404 Some host fail on `assert (!"foo")', which expands to
18405 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
18406 Reported by Nelson Beebee.
18408 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
18409 `#define it_succeeded 0' and `assert (it_succeeded)'.
18411 2001-12-17 Marc Autret <autret_m@epita.fr>
18413 * src/bison.simple: Don't hard code the skeleton line and filename.
18414 * src/output.c (output_parser): Rename 'line' as 'output_line'.
18415 New line counter 'skeleton_line' (skeleton-line muscle).
18417 2001-12-17 Paul Eggert <eggert@twinsun.com>
18419 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
18420 YYDEBUG must be defined to a nonzero value.
18422 * src/bison.simple (yytname): Do not assume that the user defines
18423 YYDEBUG to a properly parenthesized expression.
18425 2001-12-17 Akim Demaille <akim@epita.fr>
18427 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
18428 nlookaheads is a new member.
18430 * src/lalr.h (nlookaheads): Remove this orphan declaration.
18431 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
18434 2001-12-17 Akim Demaille <akim@epita.fr>
18436 * src/files.h, src/files.c (open_files, close_files): Remove.
18437 * src/main.c (main): Don't open/close files, nor invoke lex_free,
18439 * src/reader.c (reader): Do it.
18441 2001-12-17 Akim Demaille <akim@epita.fr>
18443 * src/conflicts.c (print_reductions): Formatting changes.
18445 2001-12-17 Akim Demaille <akim@epita.fr>
18447 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
18448 (flush_reduce): New.
18449 (resolve_sr_conflict): Adjust.
18451 2001-12-17 Akim Demaille <akim@epita.fr>
18453 * src/output.c (output_obstack): Be static and rename as...
18454 (format_obstack): this, to avoid any confusion with files.c's
18456 * src/reader.h (muscle_obstack): Move to...
18457 * src/output.h: here, since it's defined in output.c.
18459 2001-12-17 Akim Demaille <akim@epita.fr>
18461 * src/output.c (action_row, save_column, default_goto)
18462 (sort_actions, matching_state, pack_vector): Better variable
18465 2001-12-17 Akim Demaille <akim@epita.fr>
18467 * src/output.c: Various formatting changes.
18469 2001-12-17 Akim Demaille <akim@epita.fr>
18471 * src/files.c (output_files): Free the output_obstack.
18472 * src/main.c (main): Call print and print_graph conditionally.
18473 * src/print.c (print): Work unconditionally.
18474 * src/print_graph.c (print_graph): Work unconditionally.
18475 * src/conflicts.c (log_resolution): Output only if verbose_flag.
18477 2001-12-16 Marc Autret <autret_m@epita.fr>
18479 * src/output.c (actions_output): Fix. When we use %no-lines,
18480 there is one less line per action.
18482 2001-12-16 Marc Autret <autret_m@epita.fr>
18484 * src/bison.simple: Remove a useless #line directive.
18485 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
18486 * src/output.c (get_lines_number): New.
18487 (output_parser): Adjust, now takes care about the lines of a
18489 Fix line numbering.
18490 (actions_output): Computes the number of lines taken by actions.
18491 (output_master_parser): Insert new skeleton which is the name of
18492 the output parser file name.
18494 2001-12-15 Marc Autret <autret_m@epita.fr>
18496 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
18498 2001-12-15 Marc Autret <autret_m@epita.fr>
18500 * src/output.c (output_gram): Keep track of the hairy one.
18502 2001-12-15 Akim Demaille <akim@epita.fr>
18504 Make `make distcheck' work.
18506 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
18507 system.h which uses libgettext.h.
18509 2001-12-15 Akim Demaille <akim@epita.fr>
18511 * src/nullable.c (set_nullable): Useless rules must be skipped,
18512 otherwise, since we range over their symbols, we might look at a
18513 nonterminal which no longer ``exists'', i.e., it is not counted in
18514 `nvars', hence we overflow our arrays.
18516 2001-12-15 Akim Demaille <akim@epita.fr>
18518 The header can also be produced directly, without any obstack!
18521 * src/files.c, src/files.h (defines_obstack): Remove.
18522 (compute_header_macro): Global.
18523 (defines_obstack_save): Remove.
18524 * src/reader.c (parse_union_decl): No longer output to
18525 defines_obstack: its content can be found in the `stype' muscle
18527 (output_token_translations): Merge into...
18528 (symbols_output): this.
18530 (symbols_save): this.
18532 * src/output.c (header_output): New.
18535 2001-12-15 Akim Demaille <akim@epita.fr>
18537 * src/reader.c (parse_union_decl): Instead of handling two obstack
18538 simultaneously, use one to define the `stype' muscle, and use the
18539 value of the latter to fill defines_obstack.
18540 (copy_comment): Remove.
18541 (copy_comment2): Work for a single obstack.
18543 (copy_comment): this.
18545 2001-12-15 Akim Demaille <akim@epita.fr>
18547 * src/lex.c, src/lex.h (xgetc): No longer static.
18548 * src/reader.c (parse_union_decl): Revamp.
18550 2001-12-15 Akim Demaille <akim@epita.fr>
18552 Still making progress in separating Bison into (i) input, (ii)
18553 process, (iii) output: now we can directly output the parser file
18554 without using table_obstack at all.
18556 * src/files.c, src/files.h (table_obstack): Bye bye.
18557 (parser_file_name): New.
18558 * src/files.c (compute_output_file_names): Compute it.
18559 * src/output.c (actions_output, output_parser)
18560 (output_master_parser): To a file instead of an obstack.
18562 2001-12-15 Akim Demaille <akim@epita.fr>
18564 Attach actions to rules, instead of pre-outputting them to
18567 * src/gram.h (rule_t): action and action_line are new members.
18568 * src/reader.c (symbol_list): Likewise.
18569 (copy_action): Save the actions within the rule.
18570 (packgram): Save them in rule_table.
18571 * src/output.c (actions_output): New.
18572 (output_parser): Use it on `%%actions'.
18573 (output_rule_data): Don't free rule_table.
18575 (prepare): Don't save the `action' muscle.
18576 * src/bison.simple: s/%%action/%%actions/.
18578 2001-12-15 Akim Demaille <akim@epita.fr>
18580 * src/reader.c (copy_action): When --yacc, don't append a `;'
18581 to the user action: let it fail if lacking.
18582 Suggested by Arnold Robbins and Tom Tromey.
18584 2001-12-14 Akim Demaille <akim@epita.fr>
18586 * src/lex.c (literalchar): Simply return the char you decoded, non
18587 longer mess around with obstacks and int pointers.
18588 Adjust all callers.
18590 2001-12-14 Akim Demaille <akim@epita.fr>
18592 * src/lex.c (literalchar): Don't escape the special characters,
18593 just decode them, and keep them as char (before, eol was output as
18594 the 2 char string `\n' etc.).
18595 * src/output.c (output_rule_data): Use quotearg to output the
18598 2001-12-13 Paul Eggert <eggert@twinsun.com>
18600 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
18601 Do not infringe on the global user namespace when using C++.
18602 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
18603 All uses of `fprintf' and `stderr' changed.
18605 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
18607 2001-12-13 Akim Demaille <akim@epita.fr>
18609 The computation of nullable is broken: it doesn't handle empty
18612 * tests/torture.at (GNU AWK Grammar): New.
18613 * tests/sets.at (Nullable): New.
18614 * src/nullable.c (set_nullable): Instead of blindly looping over
18615 `ritems', loop over the rules, and then over their rhs's.
18617 Work around Autotest bugs.
18619 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
18620 frame, because Autotest understand lines starting with a `+' as
18621 traces from the shell. Then, they are not processed properly.
18622 Admittedly an Autotest bug, but we don't have time to wait for
18623 Autotest to catch up.
18624 * tests/regression.at (Broken Closure): Adjust to the new table
18627 * tests/sets.at: here.
18629 2001-12-13 Akim Demaille <akim@epita.fr>
18631 * src/closure.c (closure): Use nrules instead of playing tricks
18632 with BITS_PER_WORD.
18634 2001-12-13 Akim Demaille <akim@epita.fr>
18636 * src/print.c (print_actions): Output the handling of `$' as the
18637 traces do: shifting the token EOF. Before EOF was treated as a
18639 * tests/regression.at: Adjust some tests.
18640 * src/print_graph.c (print_core): Complete the set of items via
18641 closure. The next-to-final and final states are still unsatisfying,
18642 but that's to be addressed elsewhere.
18643 No longer output the rule numbers, but do output the state number.
18644 A single loop for the shifts + gotos is enough, but picked a
18645 distinct color for each.
18646 (print_graph): Initialize and finalize closure.
18648 2001-12-13 Akim Demaille <akim@epita.fr>
18650 * src/reader.c (readgram): Remove dead code, an strip useless
18652 (get_type): Remove, unused.
18654 2001-12-12 Akim Demaille <akim@epita.fr>
18656 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
18657 on that of lib/error.c.
18659 2001-12-12 Akim Demaille <akim@epita.fr>
18661 Some hosts don't like `/' in includes.
18663 * src/system.h: Include libgettext.h without qualifying the path.
18664 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
18667 2001-12-11 Marc Autret <autret_m@epita.fr>
18669 * src/output.c (output_parser): Remove useless muscle.
18671 2001-12-11 Marc Autret <autret_m@epita.fr>
18673 * src/bison.simple: Remove #line just before %%epilogue. It
18674 is now handled in ...
18675 * src/reader.c (read_additionnal_code): Add the output of a
18676 #line for the epilogue.
18678 2001-12-10 Marc Autret <autret_m@epita.fr>
18680 * src/reader.c (copy_definition): Re-use CPP-outed code which
18681 replace precedent remove.
18682 * src/bison.simple: Remove #line before %%prologue because
18683 %%input-line is wrong at this time.
18685 2001-12-10 Marc Autret <autret_m@epita.fr>
18687 * src/reader.c (symbols_output): Clean up.
18688 * src/output.c (output_gram, output): Clean up.
18690 2001-12-10 Akim Demaille <akim@epita.fr>
18692 * src/lalr.c (initialize_lookaheads): New. Extracted from...
18693 * src/LR0.c (set_state_table): here.
18694 * src/lalr.c (lalr): Call it.
18696 2001-12-10 Akim Demaille <akim@epita.fr>
18698 * src/state.h (shifts): Remove the `number' member: shifts are
18699 attached to state, hence no longer need to be labelled with a
18702 2001-12-10 Akim Demaille <akim@epita.fr>
18704 Now that states have a complete set of members, the linked list of
18705 shifts is useless: just fill directly the state's shifts member.
18707 * src/state.h (shifts): Remove the `next' member.
18708 * src/LR0.c (first_state, last_state): Remove.
18709 Adjust the callers.
18710 (augment_automaton): Don't look for the shifts that must be added
18711 a shift on EOF: it is those of the state we looked for! But now,
18712 since shifts are attached, it is no longer needed to looking
18713 merely by its id: its number.
18715 2001-12-10 Akim Demaille <akim@epita.fr>
18717 * src/LR0.c (augment_automaton): Better variable locality.
18718 Remove an impossible branch: if there is a state corresponding to
18719 the start symbol being shifted, then there is shift for the start
18720 symbol from the initial state.
18722 2001-12-10 Akim Demaille <akim@epita.fr>
18724 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
18725 only when appropriate: when insert_start_shifting_state' is not
18727 * tests/regression.at (Rule Line Numbers): Adjust.
18729 2001-12-10 Akim Demaille <akim@epita.fr>
18731 * src/LR0.c (augment_automaton): Now that all states have shifts,
18732 merge the two cases addition shifts to the initial state.
18734 2001-12-10 Akim Demaille <akim@epita.fr>
18736 * src/lalr.c (set_state_table): Move to...
18738 * src/lalr.c (lalr): Don't call it...
18739 * src/LR0.c (generate_states): do it.
18740 * src/LR0.h (first_state): Remove, only the table is used.
18742 2001-12-10 Akim Demaille <akim@epita.fr>
18744 * src/LR0.h (first_shift, first_reduction): Remove.
18745 * src/lalr.c: Don't use first_shift: find shifts through the
18748 2001-12-10 Akim Demaille <akim@epita.fr>
18750 * src/LR0.c: Attach shifts to states as soon as they are
18752 * src/lalr.c (set_state_table): Instead of assigning shifts to
18753 state, just assert that the mapping was properly done.
18755 2001-12-10 Akim Demaille <akim@epita.fr>
18757 * src/LR0.c (insert_start_shift): Rename as...
18758 (insert_start_shifting_state): this.
18759 (insert_eof_shifting_state, insert_accepting_state): New.
18760 (augment_automaton): Adjust.
18761 Better locality of the variables.
18762 When looking if the start_symbol is shifted from the initial
18763 state, using `while (... symbol != start_symbol ...)' sounds
18764 better than `while (... symbol < start_symbol ...)': If fail
18765 to see how the order between symbols could be relevant!
18767 2001-12-10 Akim Demaille <akim@epita.fr>
18769 * src/getargs.h: Don't declare `spec_name_prefix' and
18770 `spec_file_prefix', declared by src/files.h.
18771 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
18772 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
18773 * src/output.c (prepare): Adjust.
18774 * src/reader.c (symbols_output): Likewise.
18775 * src/vmsgetargs.c: Vaguely adjust, but who cares?
18777 2001-12-10 Akim Demaille <akim@epita.fr>
18779 * src/muscle_tab.c (muscle_init): NULL is a better default than
18782 2001-12-10 Akim Demaille <akim@epita.fr>
18784 * src/reader.c (reader): Calling symbols_output once is enough.
18786 2001-12-10 Akim Demaille <akim@epita.fr>
18788 Now that states have a complete set of members, the linked list of
18789 reductions is useless: just fill directly the state's reductions
18792 * src/state.h (struct reductions): Remove member `number' and
18794 * src/LR0.c (first_reduction, last_reduction): Remove.
18795 (save_reductions): Don't link the new reductions, store them in
18797 * src/lalr.c (set_state_table): No need to attach reductions to
18798 states, it's already done.
18799 * src/output.c (output_actions): No longer free the shifts, then
18800 the reductions, then the states: free all the states and their
18803 2001-12-10 Akim Demaille <akim@epita.fr>
18805 * src/options.c (OPTN, DRTV, BOTH): New.
18806 (option_table): Use them.
18808 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
18809 the job of system.h.
18810 * src/options.c: Don't include stdio.h and xalloc.h for the same
18813 2001-12-10 Akim Demaille <akim@epita.fr>
18815 * src/output.c (output, prepare): Make sure the values of the
18816 muscles `action' and `prologue' are 0-terminated.
18818 2001-12-10 Akim Demaille <akim@epita.fr>
18820 Clean up GCC warnings.
18822 * src/reader.c (copy_action): `buf' is not used.
18823 (parse_skel_decl): Be static.
18824 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
18825 * src/options.h (create_long_option_table): Have a real prototype.
18826 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
18827 (hash_delete_at): Return const void *.
18828 Adjust casts to preserve the const.
18830 2001-12-10 Akim Demaille <akim@epita.fr>
18832 * configure.in: Require 2.52g.
18833 M4 is not needed, but AUTOM4TE is.
18834 * m4/m4.m4: Remove.
18835 * tests/Makefile.am: Adjust.
18837 2001-12-10 Akim Demaille <akim@epita.fr>
18839 One structure for states is enough, even though theoretically
18840 there are LR(0) states and LALR(1) states.
18842 * src/lalr.h (state_t): Remove.
18843 (state_table): Be state_t **, not state_t *.
18844 * src/state.h (core, CORE_ALLOC): Rename as...
18845 (state_t, STATE_ALLOC): this.
18846 Add the LALR(1) members: shifts, reductions, errs.
18847 * src/LR0.c (state_table): Rename as...
18848 (state_hash): this, to avoid name clashes with the global
18850 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
18851 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
18853 2001-12-10 Akim Demaille <akim@epita.fr>
18855 Bison dumps core on bash.y.
18856 Reported by Pascal Bart.
18858 * src/warshall.c (bitmatrix_print): New.
18860 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
18861 j must be the outer loop.
18862 * tests/regression.at (Broken Closure): New.
18864 2001-12-05 Akim Demaille <akim@epita.fr>
18866 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
18868 Reported by Peter Hamorsky.
18870 2001-12-05 Akim Demaille <akim@epita.fr>
18872 * src/conflicts.c (err_table): Remove.
18873 (resolve_sr_conflict): Adjust.
18874 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
18876 (state_t.reductions, state_t.shifts): this.
18878 2001-12-05 Akim Demaille <akim@epita.fr>
18880 * src/reduce.c (reduce_grammar_tables): No longer disable the
18881 removal of useless rules via CPP but via `if (0)', so that the
18882 compiler still check the code is valid.
18883 For instance, it should have noticed `rline' no longer exists: use
18884 the `line' member of rule_t.
18885 * src/gram.c (dummy, rline): Remove, unused.
18887 2001-12-05 Akim Demaille <akim@epita.fr>
18889 * src/output.c (pack_vector): Use assert, not berror.
18890 * src/main.c (berror): Remove, unused.
18892 2001-12-05 Akim Demaille <akim@epita.fr>
18894 New experimental feature: if --verbose --trace output all the
18895 items of a state, not only its kernel.
18897 * src/print.c (print_core): If `trace_flag', then invoke closure
18898 before outputting the items of the state (print_core is no longer
18899 a correct name them).
18900 (print_results): Invoke new_closure/free_closure if needed.
18902 2001-12-05 Akim Demaille <akim@epita.fr>
18904 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
18905 * src/closure.c, src/closure.h (itemsetsize): Rename as...
18906 (nitemset): for consistency with the rest of the project.
18908 2001-12-05 Akim Demaille <akim@epita.fr>
18910 * src/closure.c (print_closure): Improve.
18911 (closure): Use it for printing input and output.
18913 2001-12-05 Akim Demaille <akim@epita.fr>
18915 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
18916 indexed by nonterminals.
18918 2001-12-05 Akim Demaille <akim@epita.fr>
18920 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
18922 * src/warshall.h: Remove accidental duplication of the content.
18924 2001-12-05 Akim Demaille <akim@epita.fr>
18926 * src/closure.c (set_fderives): De-obfuscate.
18928 2001-12-05 Akim Demaille <akim@epita.fr>
18930 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
18932 2001-12-05 Akim Demaille <akim@epita.fr>
18934 * src/closure.c (set_firsts): De-obfuscate.
18936 2001-12-05 Akim Demaille <akim@epita.fr>
18938 * src/output.c (action_row): De-obfuscate
18939 using the good o' techniques: arrays not pointers, variable
18940 locality, BITISSET, RESETBIT etc.
18942 2001-12-05 Akim Demaille <akim@epita.fr>
18944 Pessimize the code to simplify it: from now on, all the states
18945 have a valid SHIFTS, which NSHIFTS is possibly 0.
18947 * src/LR0.c (shifts_new): Be global and move to..
18948 * src/state.c, src/state.h: here.
18949 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
18950 * src/print_graph: Adjust.
18952 2001-12-05 Akim Demaille <akim@epita.fr>
18954 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
18955 * src/conflicts.c: Use it.
18956 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
18957 incorrectly ``simplified''.
18959 2001-12-05 Akim Demaille <akim@epita.fr>
18961 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
18962 using the good o' techniques: arrays not pointers, variable
18963 locality, BITISSET, RESETBIT etc.
18965 2001-12-05 Akim Demaille <akim@epita.fr>
18967 * src/state.h (SHIFT_SYMBOL): New.
18968 * src/conflicts.c: Use it to deobfuscate.
18970 2001-12-05 Akim Demaille <akim@epita.fr>
18972 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
18973 (print_reductions): De-obfuscate using the good o' techniques:
18974 arrays not pointers, variable locality, BITISSET.
18976 2001-12-05 Akim Demaille <akim@epita.fr>
18978 * src/conflicts.c (print_reductions): Arrays, not pointers.
18981 2001-12-05 Akim Demaille <akim@epita.fr>

18985 2001-12-05 Akim Demaille <akim@epita.fr>
18987 * src/conflicts.c (print_reductions): Improve variable locality.
18989 2001-12-05 Akim Demaille <akim@epita.fr>
18991 * src/conflicts.c (print_reductions): Pessimize, but clarify.
18993 2001-12-05 Akim Demaille <akim@epita.fr>
18995 * src/conflicts.c (print_reductions): Improve variable locality.
18997 2001-12-05 Akim Demaille <akim@epita.fr>
18999 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
19000 * src/lalr.c: Use them.
19002 2001-12-05 Akim Demaille <akim@epita.fr>
19004 * src/LR0.c (augment_automaton): Formatting changes.
19005 Better variable locality.
19007 2001-12-05 Akim Demaille <akim@epita.fr>
19009 * src/lalr.c (matrix_print): New.
19010 (transpose): Use it.
19011 Use arrays instead of pointers.
19013 2001-12-05 Akim Demaille <akim@epita.fr>
19015 * src/lalr.c (maxrhs): Move to...
19016 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
19017 * src/lalr.c (build_relations): Adjust.
19019 2001-12-05 Akim Demaille <akim@epita.fr>
19021 * src/lalr.c (transpose): Free the memory allocated to the
19022 argument, as it is replaced by the results by the unique caller.
19023 (build_relations): Merely invoke transpose: it handles the memory
19025 Improve variable locality.
19026 Avoid variables used as mere abbreviations.
19027 (compute_lookaheads): Use arrays instead of pointers.
19029 2001-12-05 Akim Demaille <akim@epita.fr>
19031 * src/lalr.c (initialize_F): Improve variable locality.
19032 Avoid variables used as mere abbreviations.
19034 2001-12-05 Akim Demaille <akim@epita.fr>
19036 * src/derives.c (print_derives): Display the ruleno.
19037 * src/lalr.c (initialize_F, transpose): Better variable locality
19038 to improve readability.
19039 Avoid variables used as mere abbreviations.
19041 2001-12-05 Akim Demaille <akim@epita.fr>
19043 * src/lalr.c (traverse): Use arrays instead of pointers.
19045 2001-12-05 Akim Demaille <akim@epita.fr>
19047 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
19048 the handling of squeue.
19049 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19051 2001-12-05 Akim Demaille <akim@epita.fr>
19053 Because useless nonterminals are now kept alive (instead of being
19054 `destroyed'), we now sometimes examine them, and store information
19055 related to them. Hence we need to know their number, and adjust
19056 memory allocations.
19058 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
19060 * src/LR0.c (allocate_itemsets): The memory allocated to
19061 `symbol_count' was used for two different purpose: once to count
19062 the number of occurrences of each symbol, and later reassigned to
19063 `shift_symbol', containing the symbol that can be shifted from a
19065 Deobfuscate, i.e., allocate, use and free `symbol_count' here
19067 (new_itemsets): Allocate `shift_symbol' here.
19068 (allocate_itemsets): symbol_count includes useless nonterminals.
19069 Make room for them.
19070 (free_storage): Use `free', not `XFREE', for pointers that cannot
19073 2001-12-05 Akim Demaille <akim@epita.fr>
19075 * src/nullable.c (set_nullable): Deobfuscate the handling of
19077 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19079 2001-12-05 Akim Demaille <akim@epita.fr>
19081 * src/gram.c, src/gram.h (ritem_print): New.
19082 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
19083 (This useless function was defined only to work around VMS linkers
19084 that can't handle compilation units with variables only).
19085 * src/reduce.c (dump_grammar): Use it to trace the construction of
19088 2001-12-04 Paul Eggert <eggert@twinsun.com>
19090 * src/bison.simple (union yyalloc): Change member names
19091 to be the same as the stack names.
19092 (yyparse): yyptr is now union yyalloc *, not char *.
19093 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
19094 and may generate better code on some machines.
19095 (yystpcpy): Use prototype if __STDC__ is defined, not just
19096 if __cplusplus is defined.
19098 2001-11-30 Akim Demaille <akim@epita.fr>
19100 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
19101 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
19102 Gettext doesn't compile cleanly, and dies with -Werror.
19103 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
19104 Include WARNING_CFLAGS here.
19105 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
19106 before being defined.
19108 2001-11-27 Paul Eggert <eggert@twinsun.com>
19110 * lib/quotearg.h (quotearg_n, quotearg_n_style):
19111 First arg is int, not unsigned.
19112 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
19113 (SIZE_MAX, UINT_MAX): New macros.
19114 (quotearg_n_options): Abort if N is negative.
19115 Avoid overflow check on hosts where size_t is 64 bits and int
19116 is 32 bits, as overflow is impossible there.
19117 Fix off-by-one typo that caused unnecessary reallocation.
19119 2001-11-29 Paul Eggert <eggert@twinsun.com>
19121 Name space cleanup in generated parser.
19123 * doc/bison.texinfo (Bison Parser): Discuss system headers
19124 and their effect on the user name space.
19126 * src/bison.simple:
19127 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
19128 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
19129 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
19131 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
19132 on user names when possible.
19134 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
19135 Simplify test for whather <alloca.h> exists.
19137 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
19139 (<stdio.h>): Include if YYDEBUG.
19141 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
19142 ! defined (yyoverflow) && ! defined (yymemcpy).
19144 (yymemcpy, yyparse): Rename local variables as needed so that
19145 they all begin with 'yy'.
19147 (yystrlen, yystpcpy): New functions.
19149 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
19152 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
19153 instead of relying on string.h functions. Use YYSTACK_ALLOC
19154 and YYSTACK_FREE instead of malloc and free.
19156 2001-11-30 Akim Demaille <akim@epita.fr>
19158 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
19159 before their first uses.
19160 (YYBISON, YYPURE): Move to the top of the output.
19162 2001-11-30 Akim Demaille <akim@epita.fr>
19164 * tests/reduce.at (Useless Nonterminals): Fix.
19166 2001-11-30 Akim Demaille <akim@epita.fr>
19168 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
19169 if body instead of `;' to pacify GCC's warnings.
19171 2001-11-30 Akim Demaille <akim@epita.fr>
19173 Instead of mapping the LHS of unused rules to -1, keep the LHS
19174 valid, but flag the rules as invalid.
19176 * src/gram.h (rule_t): `useful' is a new member.

21286 Adjust dependencies.
21288 2000-11-03 Akim Demaille <akim@epita.fr>
21290 For some reason, this was not applied.
21292 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

21305 (done): Rename as...
21306 (output_files): this.
21307 Use `obstack_save'.
21308 * src/main.c (main): Don't use `atexit' to register `done', since
21309 it no longer has to remove tmp files, just call `output_files'
21310 when there are no errors.
21312 2000-11-02 Akim Demaille <akim@epita.fr>
21314 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

21386 (copy_guard): Adjust.
21388 2000-10-16 Akim Demaille <akim@epita.fr>

21414 2000-10-04 Akim Demaille <akim@epita.fr>
21416 When a literal string is used to define two different tokens,
21417 `bison -v' segfaults.
21418 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
21420 * tests/regression.m4: New file.
21421 Include the core of the sample provided by Piotr Gackiewicz.
21422 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
21425 2000-10-04 Akim Demaille <akim@epita.fr>

21442 2000-10-02 Akim Demaille <akim@epita.fr>
21444 * src/derives.c, src/print.c, src/reduce.c: To ease the
21445 translation, move some `\n' out of the translated strings.
21447 2000-10-02 Akim Demaille <akim@epita.fr>
21449 The location tracking mechanism is precious for parse error
21450 messages. Nevertheless, it is enabled only when `@n' is used in
21451 the grammar, which is a different issue (you can use it in error
21452 message, but not in the grammar per se). Therefore, there should
21453 be another means to enable it.
21455 * src/getargs.c (getargs): Support `--locations'.
21456 (usage): Report it.
21457 * src/getargs.h (locationsflag): Export it.
21458 * src/lex.c (percent_table): Support `%locations'.
21459 * src/reader.c (yylsp_needed): Remove this variable, now replaced
21460 with `locationsflag'.
21461 * doc/bison.texinfo: Document `--locations' and `%locations'.
21463 * tests/calc.m4: Test it.
21465 For regularity of the names, replace each
21466 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
21467 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
21468 In addition replace each `flag' with `_flag'.
21470 2000-10-02 Akim Demaille <akim@epita.fr>
21472 Also test parse error messages, including with YYERROR_VERBOSE.
21474 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
21476 Use it to check the computations.
21477 Use it to check `nonassoc' is honored.
21478 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
21479 `--yyerror-verbose'.
21480 (_AT_CHECK_CALC): Adjust to this option.
21481 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
21483 2000-10-02 Akim Demaille <akim@epita.fr>
21485 Test also `--verbose', `--defines' and `--name-prefix'. Testing
21486 the latter demonstrates a flaw in the handling of non debugging
21487 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
21488 was used in order to simplify:
21504 unfortunately this leads to a CPP conflict when
21505 `--name-prefix=foo' is used since it produces `#define yydebug
21508 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
21509 (YYDPRINTF): New macro.
21511 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
21513 Also test `--verbose', `--defines' and `--name-prefix'.

21517 Improve the readability of the produced parsers.
21519 * src/bison.s1: Formatting changes.
21520 Improve the comment related to the `$' mark.
21521 (yydefault): Don't fall through to `yyresume': `goto' there.
21522 * src/output.c (output_parser): When the `$' is met, skip the end
21524 New variable, `number_of_dollar_signs', to check there's exactly
21525 one `$' in the parser skeleton.
21527 2000-10-02 Akim Demaille <akim@epita.fr>
21529 * lib/xstrdup.c: New file, from the fileutils.
21530 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
21531 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
21532 instead of strlen + xmalloc + strcpy.
21533 * src/symtab.c (copys): Remove, use xstrdup instead.
21535 2000-10-02 Akim Demaille <akim@epita.fr>
21537 * src/gram.h (associativity): New enum type which replaces the
21538 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
21539 `right_assoc', `left_assoc' and `non_assoc'.
21540 Adjust all dependencies.
21541 * src/reader.c: Formatting changes.
21542 (LTYPESTR): Don't define it, use it as a literal in
21543 `reader_output_yylsp'.
21544 * src/symtab.h (symbol_class): New enum type which replaces the
21545 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
21546 `sunknown', `stoken and `snterm'.
21548 2000-10-02 Akim Demaille <akim@epita.fr>
21550 * src/getargs.c (fixed_outfiles): Rename as...
21551 (yaccflag): for consistency and accuracy.
21552 Adjust dependencies.
21554 2000-10-02 Akim Demaille <akim@epita.fr>
21556 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21557 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21558 difficult and introduced a lot of core dump. It turns out that
21559 Bison used an implementation of `xmalloc' based on `calloc', and
21560 at various places it does depend upon the initialization to 0. I
21561 have not tried to isolate the pertinent places, and all the former
21562 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
21563 someone should address this issue.
21565 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
21566 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

21576 * src/system.h: Include `assert.h'.
21578 2000-10-02 Akim Demaille <akim@epita.fr>
21580 * src/state.h (nstates, final_state, first_state, first_shift)
21581 (first_reduction): Move their exportation from here...
21582 * src/LR0.h: to here.
21583 Adjust dependencies.
21584 * src/getargs.c (statisticsflag): New variable.
21585 Add support for `--statistics'.

21588 Remove a lot of now useless `extern' statements in most files.
21590 2000-10-02 Akim Demaille <akim@epita.fr>
21592 * src/LR0.h: New file.
21595 2000-10-02 Akim Demaille <akim@epita.fr>

21622 Propagate its inclusion.
21623 * src/reduce.c: Topological sort and other formatting changes.
21624 (bool, TRUE, FALSE): Move their definition to...
21625 * src/system.h: here.
21627 2000-10-02 Akim Demaille <akim@epita.fr>
21629 * src/files.c: Formatting changes.
21630 (tryopen, tryclose, openfiles): Rename as...
21631 (xfopen, xfclose, open_files): this.
21632 (stringappend): static.
21633 * src/files.h: Complete the list of exported symbols.

21656 * src/lalr.c: Formatting changes, topological sorting etc.
21658 2000-10-02 Akim Demaille <akim@epita.fr>
21660 * src/output.c (token_actions): Introduce a temporary array,
21661 YYDEFACT, that makes it possible for this function to use
21662 output_short_table.
21664 2000-10-02 Akim Demaille <akim@epita.fr>
21666 `user_toknums' is output as a `short[]' in `output.c', while it is
21667 defined as a `int[]' in `reader.c'. For consistency with the
21668 other output tables, `user_toknums' is now defined as a table of

21712 * src/system.h: Define PARAMS.
21713 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
21714 purpose of config.h. system.h must not try to fix wrong
21715 definitions in config.h.

21972 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

22699 (parse_percent_token): Added % declarations as another
22700 way to specify the flags -n, -l, and -r. Also added hooks for
22701 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
22702 major changes to files.c.
