3 Use locations in the variant example.
4 Yes, this obfuscates the point of this example, variants only. But glr.cc
5 cannot work (yet?) without locations. This change makes it easier to use
6 this example with glr.cc.
8 * examples/variant.yy (assert): %define it.
9 (locations): Request them.

234 Fix portability issue in the test suite.
235 * tests/local.at (AT_MATCHES_CHECK): New.
236 Based on Perl instead of Sed. Sed has too many portability

273 Implement the FIXME that ends an user action with a semicolon
274 if it seems necessary.
275 * src/scan-code.l (flex rules section): Flag cpp directive from
276 any `#' to the first unescaped end-of-line. Semicolon is not
277 needed after `;', `{', '}', or cpp directives and is needed after
278 any other token (whitespaces and comments have no effect).

316 * data/glr.cc: Adjust.
317 * data/lalr1.java: Adjust the %destructor sanity check.
318 * src/output.c (symbol_code_props_output): Remove, we no longer

344 2008-12-01 Akim Demaille <demaille@gostai.com>
346 Use the symbol properties to output the printer/destructor for lalr1.cc.
347 Instead of defining complex list of tuples to define various
348 properties of the symbols, we now prefer to define symbols as
349 "structs" in m4: using the symbol key (its number), and the
350 property name, b4_symbol gives it value. Use this to handle
351 destructors and printers.
353 * src/output.c (CODE_PROP): New.
354 (prepare_symbol_definitions): Use it to define the printer and
355 destructor related attributes of the symbols.

370 Remove spurious empty line before syncline.
371 * data/bison.m4 (b4_syncline): Don't output an empty line before
374 2008-11-26 Akim Demaille <demaille@gostai.com>
376 Convert lib/Makefile.am into lib/local.mk.
377 The real problem is rather gnulib.mk, which itself is extracted
378 from a Makefile.am that gnulib expects to the "recursive". The
379 tool prefix-gnulib-mk converts such a gnulib.mk to be
380 non-recursive. Also, some AC_SUBST variables need to be adjusted.
382 * etc/prefix-gnulib-mk: New.
383 * bootstrap (slurp): Use it to convert further gnulib.mk.
384 No longer try to avoid re-creation of lib/gnulib.mk as the changes
386 * lib/Makefile.am: Rename as...
387 * lib/local.mk: this.
388 Adjust to be prefixed.
389 * Makefile.am, configure.ac: Adjust.
390 * src/local.mk (AM_CPPFLAGS): Extend it, don't define it.
392 2008-11-26 Akim Demaille <demaille@gostai.com>
395 * tests/local.mk (TESTSUITE_FLAGS, AUTOTEST_FLAGS): Rename as...
396 (TESTSUITEFLAGS, AUTOTESTFLAGS): these to compy with the GCS.

403 (deterministic integral) tables by hand.
405 2008-11-26 Akim Demaille <demaille@gostai.com>
407 Use b4_parser_tables_define in Java.

430 (yyrline_): Move the comment where it is actually used.
431 * data/yacc.c: Adjust.
432 (yyrline): Use b4_integral_parser_table_define.
434 2008-11-26 Akim Demaille <demaille@gostai.com>
437 * src/parse-gram.h, src/parse-gram.c: Regen.

447 * data/c.m4 (b4_table_define): New.
448 * data/yacc.c: Use b4_tables_define instead of output the tables
450 * tests/regression.at (Web2c Actions): Adjust the expected output,
451 the order of the tables changed.
453 2008-11-26 Akim Demaille <demaille@gostai.com>
455 Get rid of (yy)rhs and (yy)prhs.
456 These tables are no longer needed in the parsers, and they don't seem to
457 be useful. They are not documented either.
459 * src/output.c (prepare_rules): Get rid of rhs and prhs.
460 Adjust the computation of (yy)r2.
462 2008-11-26 Akim Demaille <demaille@gostai.com>
464 Rule length is unsigned.
465 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
467 2008-11-26 Akim Demaille <demaille@gostai.com>
469 Get rid of lalr1-split.cc.
470 It was no longer maintainer.
472 * data/lalr1-split.cc: Remove.
473 * etc/bench.pl.in (bench_fusion_parser): Remove.
476 2008-11-26 Akim Demaille <demaille@gostai.com>
478 Use yy* consistently.
479 * data/glr.c: Now that yyrhs no longer exists as a global
480 variable, rename local "rhs" variables into "yyrhs" for
483 2008-11-25 Akim Demaille <demaille@gostai.com>
485 Get rid of yyrhs and yyprhs in glr.c.
486 * data/glr.c (yyrhs, yyprhs): Remove.
487 Instead, use the state stack and yystos.
489 2008-11-25 Akim Demaille <demaille@gostai.com>
492 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
493 as an Autotest keyword.
495 2008-11-25 Akim Demaille <demaille@gostai.com>
497 Prefer TESTSUITE_FLAGS.
498 TESTSUITEFLAGS is barely readable.
500 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
501 for backward compatibility.
502 Use the former instead of the latter.
504 2008-11-25 Akim Demaille <demaille@gostai.com>
506 Get rid of yyrhs and yyprhs in larl1.java.
507 * data/lalr1.java (yyrhs_, yyprhs_): Remove.
508 (yy_reduce_print): Rather, use yystos_ and the state stack.
510 2008-11-25 Akim Demaille <demaille@gostai.com>
514 2008-11-25 Akim Demaille <demaille@gostai.com>
516 Get rid of yyrhs and yyprhs in yacc.c.
517 They were used to get the symbol types, given a rule number, when
518 displaying the top of the stack before a reduction. But the
519 symbol type is available from the state stack. This has two be
520 benefits: two tables less in the parser (making it smaller), and a
521 more consistent use of the three stacks which will help to fuse
524 * data/yacc.c (yyprhs, yyrhs): Remove.
525 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
526 (yy_reduce_print): Take yyssp as argument.
527 Use it, together with yystos, to get the symbol type.
528 * tests/regression.at (Web2c Report): Remove these tables from the
531 2008-11-25 Akim Demaille <demaille@gostai.com>
534 The point is to factor the generation of the tables across skeletons.
535 This is language dependant.
537 * data/c.m4 (b4_comment_): New.
538 Should be usable to define how to generate tables independently of
541 (b4_comment): Bounce to b4_c_comment.
542 Now support $2 = [PREFIX] for indentation.
543 * data/lalr1.cc (b4_table_declare): Don't output a comment if
545 Indent it properly when there is one.
546 Output the ending semicolon.
547 (b4_table_define): Space changes.
548 Output the ending semicolon.
549 (b4_tables_map): New.
550 Use it twice instead of declaring and defining the (integral)
553 2008-11-25 Akim Demaille <demaille@gostai.com>
556 * data/lalr1.cc (b4_table_declare): New.
557 Use it to declare the tables defined with b4_table_define.
558 (b4_table_define): Declare a third arg to match b4_table_declare
560 Move all the comments around invocations of b4_table_define into
561 the invocations itselves.

717 Support parametric types.
719 There are two issues to handle: first scanning nested angle
720 bracket pairs to support types such as std::pair< std::string,
721 std::list<std::string> > >.
723 Another issue is to address idiosyncracies of C++: do not glue two
724 closing angle brackets together (otherwise it's operator>>), and
725 avoid sticking blindly a TYPE to the opening <, as it can result
726 in '<:' which is a digraph for '['.
728 * src/scan-gram.l (brace_level): Rename as...
731 Implement support for complex tags.
734 * data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)
735 (b4_symbol_variant): Leave space around types as parameters.

745 This is not sufficient, but we test at least that the make_SYMBOL
746 interface is not affected by token.prefix. A more general test
747 will be implemented when the support of token.prefix is generalized

824 Move sc_tight_scope into maint.mk.
825 It does not work, and I don't know how it was supposed to work: it
826 seems to be looking for sources in the build tree. I just moved
827 it at a better place, fixing it is still required.

851 * Makefile.am, configure.ac: Adjust.
852 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
853 include "..." to find files "here": we are no longer in src/, so
854 qualify the includes with src/.

909 Always qualify initial line and column literals as unsigned.
910 (location::location): Provide convenience constructors.

914 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
916 Using template buys us nothing, and makes it uselessly complex to
917 construct a symbol. Besides, it could not be generalized to other
918 languages, while make_FOO would work in C/Java etc.
920 * data/lalr1.cc (b4_symbol_): New.
922 (b4_symbol_constructor_declaration_)
923 (b4_symbol_constructor_definition_): Instead of generating
924 specializations of an overloaded template function, just generate
925 several functions whose names are forged from the token names
926 without the token.prefix.
927 (b4_symbol_constructor_declarations): Generate them for all the
928 symbols, not just by class of symbol type, now that instead of
929 specializing a function template by the token, we generate a
930 function named after the token.
931 (b4_symbol_constructor_specialization_)
932 (b4_symbol_constructor_specializations): Remove.
933 * etc/bench.pl.in: Adjust to this new API.
935 2008-11-13 Akim Demaille <demaille@gostai.com>
937 %define token.prefix.
938 Provide a means to add a prefix to the name of the tokens as
939 output in the generated files. Because of name clashes, it is
940 good to have such a prefix such as TOK_ that protects from names
941 such as EOF, FILE etc. But it clutters the grammar itself.
943 * data/bison.m4 (token.prefix): Empty by default.
944 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
945 * data/lalr1.cc (b4_symbol): Ditto.
947 2008-11-13 Akim Demaille <demaille@gostai.com>
949 Compute at M4 time some of the subtractions.

951 (b4_rhs_data): Use it.
953 2008-11-13 Akim Demaille <demaille@gostai.com>
956 This allows the user to get the type of a token returned by yylex.
958 * data/lalr1.cc (symbol::token): New.
959 (yytoknum_): Define when %define lex_symbol, independently of
961 (yytoken_number_): Move into...
962 (symbol::token): here, since that's the only use.
963 The other one is YYPRINT which was not officially supported
964 by lalr1.cc, and anyway it did not work since YYPRINT uses this
965 array under a different name (yytoknum).
967 2008-11-13 Akim Demaille <demaille@gostai.com>

981 yytranslate and yytoknum tables.
983 2008-11-13 Akim Demaille <demaille@gostai.com>
985 Define make_symbol in the header.
986 To reach good performances these functions should be inlined (yet
987 this is to measure precisely). To this end they must be available
990 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
991 location_type with the class name.
992 Since will now be output in the header, declare "inline".
993 No longer use b4_symbol_constructor_specializations, but
994 b4_symbol_constructor_definitions in the header.
995 Don't call it in the *.cc file.
997 2008-11-13 Akim Demaille <demaille@gostai.com>
999 Define yytranslate in the header for lex_symbol.
1000 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
1001 into the header file when using %define lex_symbol.
1002 (yytranslate_): Declare inline.
1004 2008-11-13 Akim Demaille <demaille@gostai.com>
1006 Define the constructors of symbol_type in
1007 b4_symbol_constructor_definitions.
1008 The constructors are called by the make_symbol functions, which a
1009 forthcoming patch will move elsewhere. Hence the interest of
1010 putting them together.
1012 The stack_symbol_type does not need to be moved, it is used only
1015 * data/lalr1.cc: Move symbol_type and symbol_base_type
1016 constructors into...
1017 (b4_symbol_constructor_definitions): here.
1020 2008-11-13 Akim Demaille <demaille@gostai.com>
1022 Make it easier to move the definition of yytranslate_.
1023 Forthcoming changes will make it possible to use yytranslate_
1024 from outside the parser implementation file.
1026 * data/lalr1.cc (b4_yytranslate_definition): New.
1029 2008-11-13 Akim Demaille <demaille@gostai.com>
1031 Remove useless class specification.
1032 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
1033 to refer to the class name to use a type defined by the class for
1034 arguments of member functions.
1036 2008-11-13 Akim Demaille <demaille@gostai.com>
1038 Finer input type for yytranslate.
1039 This patch is debatable: the tradition expects yylex to return an int
1040 which happens to correspond to token_number (which is an enum). This
1041 allows for instance to return characters (such as '*' etc.). But this
1042 goes against the stronger typing I am trying to have with the new
1043 lex interface which return a symbol_type. So in this case, feed
1044 yytranslate_ with a token_type.
1046 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
1047 expect a token_type.
1049 2008-11-13 Akim Demaille <demaille@gostai.com>
1051 Honor lex-params in %define lex_symbol mode.
1052 * data/lalr1.cc: Use b4_lex_param.
1054 2008-11-13 Akim Demaille <demaille@gostai.com>
1057 * src/output.c (symbol_definitions_output): Rename symbol
1058 attributes type_name and has_type_name as type and has_type.
1059 * data/lalr1.cc: Adjust uses.
1061 2008-11-13 Akim Demaille <demaille@gostai.com>
1063 Use b4_type_names for the union type.
1064 The union used to compute the size of the variant used to iterate
1065 over the type of all the symbols, with a lot of redundancy. Now
1066 iterate over the lists of symbols having the same type-name.
1068 * data/lalr1.cc (b4_char_sizeof_): New.
1069 (b4_char_sizeof): Use it.
1070 Adjust to be called with a list of numbers instead of a single
1072 Adjust its caller for new-line issues.
1074 2008-11-13 Akim Demaille <demaille@gostai.com>
1076 Define the "identifier" of a symbol.
1077 Symbols may have several string representations, for instance if
1078 they have an alias. What I call its "id" is a string that can be
1079 used as an identifier. May not exist.
1081 Currently the symbols which have the "tag_is_id" flag set are
1082 those that don't have an alias. Look harder for the id.
1084 * src/output.c (is_identifier): Move to...
1085 * src/symtab.c (is_identifier): here.
1086 * src/symtab.h, src/symtab.c (symbol_id_get): New.
1087 * src/output.c (symbol_definitions_output): Use it to define "id"
1089 Remove the definition of "tag_is_id".
1090 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
1091 "tag_is_id" were used to produce code.
1092 We still use "tag" for documentation.
1094 2008-11-11 Akim Demaille <demaille@gostai.com>
1096 Locations are no longer required by lalr1.cc.
1097 * data/lalr1.cc (_b4_args, b4_args): New.
1098 Adjust all uses of locations to make them optional.
1099 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
1100 (AT_CHECK_NAMESPACE): Check the use of locations.
1101 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
1102 without locations with lalr1.cc.
1104 * tests/output.at: Check lalr1.cc with and without location
1106 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
1107 Don't use locations.

1154 Make it possible to return a symbol_type from yylex.
1155 * data/lalr1.cc (b4_lex_symbol_if): New.
1156 (parse): When lex_symbol is defined, expected yylex to return the
1158 * etc/bench.pl.in (generate_grammar_list): Extend to support this
1160 (bench_variant_parser): Exercise it.
1162 2008-11-11 Akim Demaille <demaille@gostai.com>

1192 Let yytranslate handle the eof case.
1193 * data/lalr1.cc (yytranslate_): Handle the EOF case.
1195 No longer expect yychar to be equal to yyeof_, rather, test the

1200 yychar cannot be empty in yyerrlab.

1215 Less memory pressure on the "list" bench.
1216 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
1217 the values, to limit memory pressure.
1219 2008-11-11 Akim Demaille <demaille@gostai.com>
1221 Introduce make_symbol.
1222 make_symbol provides a means to construct a full symbol (kind,
1223 value, location) in a single shot. It is meant to be a Symbol
1224 constructor, parameterized by the symbol kind so that overloading
1225 would prevent incorrect kind/value pairs. Unfortunately
1226 parameterized constructors do not work well in C++ (unless the
1227 parameter also appears as an argument, which is not acceptable),
1228 hence the use of a function instead of a constructor.
1230 * data/lalr1.cc (b4_symbol_constructor_declaration_)
1231 (b4_symbol_constructor_declarations)
1232 (b4_symbol_constructor_specialization_)
1233 (b4_symbol_constructor_specializations)
1234 (b4_symbol_constructor_definition_)
1235 (b4_symbol_constructor_definitions): New.
1236 Use them where appropriate to generate declaration, declaration of
1237 the specializations, and implementations of the templated
1238 overloaded function "make_symbol".
1239 (variant::variant): Always define a default ctor.
1240 Also provide a copy ctor.
1241 (symbol_base_type, symbol_type): New ctor overloads for value-less
1243 (symbol_type): Now public, so that functions such as yylex can use
1246 2008-11-11 Akim Demaille <demaille@gostai.com>
1248 Inform m4 whether a tag is a valid id.
1249 * src/output.c (is_identifier): New.
1250 (symbol_definitions_output): Use it to define tag_is_id.
1251 But maybe this should be done at m4 level?
1253 2008-11-11 Akim Demaille <demaille@gostai.com>
1255 Test 214 was failing: it greps with a pattern containing [ ]*
1256 which obviously meant to catch spaces and tabs, but contained only
1257 spaces. Tabulations in sources are a nuisance, so to simplify the
1258 matter, get rid of all the tabulations in the Java sources. The
1259 other skeletons will be treated equally later.
1261 * data/java.m4, data/lalr1.java: Untabify.
1262 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
1263 tabulations are no longer generated.
1265 2008-11-11 Paolo Bonzini <bonzini@gnu.org>
1267 * bootstrap.conf: Replace m4/warning.m4 with warnings module.

1275 Workaround Java's ``code too large'' problem for parser tables
1276 in most cases, by using one function per initialization.
1277 * data/java.m4 (b4_typed_parser_table, b4_integral_parser_table): New.
1278 * data/lalr1.java (yypact_, yydefact_, yypgoto_, yydefgoto_,

1300 the other skeletons.
1301 (b4_user_post_prologue): Add. Don't silently drop.
1303 (parse): Inline yylex.

1334 * data/lalr1.java (Lexer.yyerror): Use longer parameter name.
1335 (yyerror): Change to public. Add Javadoc comments. Use longer
1336 parameter names. Make the body rather than the declarator
1337 conditional on %locations.

1366 More information about the symbols.
1367 * src/output.c (type_names_output): Document all the symbols,
1368 including those that don't have a type-name.
1369 (symbol_definitions_output): Define "is_token" and
1371 * data/lalr1.cc (b4_type_action_): Skip symbols that have an empty
1372 type-name, now that they are defined too in b4_type_names.

1378 2008-11-10 Akim Demaille <demaille@gostai.com>

1389 Avoid trailing spaces.
1390 * data/c.m4: b4_comment(TEXT): Don't indent empty lines.
1391 * data/lalr1.cc: Don't indent before rule and symbol actions, as
1392 they can be empty, and anyway this incorrectly indents the first

1399 2008-11-10 Akim Demaille <demaille@gostai.com>

1441 2008-11-10 Akim Demaille <demaille@gostai.com>
1443 Change the handling of the symbols in the skeletons.
1444 Before we were using tables which lines were the symbols and which
1445 columns were things like number, tag, type-name etc. It is was
1446 difficult to extend: each time a column was added, all the numbers had
1447 to be updated (you asked for colon $2, not for "tag"). Also, it was
1448 hard to filter these tables when only a subset of the symbols (say the
1449 tokens, or the nterms, or the tokens that have and external number
1450 *and* a type-name) was of interest.
1452 Now instead of monolithic tables, we define one macro per cell. For
1453 instance "b4_symbol(0, tag)" is a macro name which contents is
1454 self-decriptive. The macro "b4_symbol" provides easier access to
1457 * src/output.c (type_names_output): Remove.
1458 (symbol_numbers_output, symbol_definitions_output): New.
1459 (muscles_output): Call them.

1499 Use it with and without %define assert.
1501 2008-11-10 Akim Demaille <demaille@gostai.com>
1503 Add %precedence support.
1504 Unfortunately it is not possible to reuse the %prec directive. This
1505 is because to please POSIX, we do not require to end the rules with a
1506 semicolon. As a result,
1510 is ambiguous: either a rule which precedence is that of baz, or a rule,
1511 and then a declaration of the precedence of the token baz.
1513 * doc/bison.texinfo: Document %precedence.
1514 (Precedence Only): New.
1515 * src/assoc.h, src/assoc.c (precedence_assoc): New.

1611 Rename data_type and stack_symbol_type.

1617 Handle semantic value and location together.
1618 * data/lalr1.cc (b4_symbol_actions): Bounce $$ and @$ to
1619 yydata.value and yydata.location.
1620 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_)

1641 Rely on the state stack to display reduction traces.
1642 To display rhs symbols before a reduction, we used information
1643 about the rule reduced, which required the tables yyrhs and
1644 yyprhs. Now use rely only on the state stack to get the same

1773 Add "%define assert" to variants.
1774 This is used to help the user catch cases where some value gets
1775 ovewritten by a new one. This should not happen, as this will
1778 Unfortunately this uncovered a bug in the C++ parser itself: the
1779 lookahead value was not destroyed between two calls to yylex. For
1780 instance if the previous lookahead was a std::string, and then an int,
1781 then the value of the std::string was correctly taken (i.e., the
1782 lookahead was now an empty string), but std::string structure itself
1785 This is now done in variant::build(other&) (which is used to take the
1786 value of the lookahead): other is not only stolen from its value, it
1787 is also destroyed. This incurs a new performance penalty of a few
1788 percent, and union becomes faster again.

2067 2008-11-03 Akim Demaille <demaille@gostai.com>
2069 Fuse the three stacks into a single one.
2071 In order to make it easy to perform benchmarks to ensure that
2072 there are no performance loss, lalr1.cc is forked into
2073 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
2076 Meanwhile, to make sure that lalr1-fusion.cc is correctly
2077 exercized by the test suite, the user must install a symbolic link
2078 from lalr1.cc to it.
2080 Instead of having three stacks (state, value, location), use a
2081 stack of triples. This considerably simplifies the code (and it
2082 will be easier not to require locations as currently does the C++
2083 parser), and also gives a 10% speedup according to
2084 etc/bench (probably mainly since memory allocation is done once
2085 instead of three times).
2087 Another motivation is to make it easier to destruct properly
2088 semantic values: now that they are bound to their state (hence
2089 symbol type) it will be easier to call the appropriate destructor.
2091 These changes should probably benefit the C parser too.
2093 * data/lalr1.cc: Copy as...
2094 * data/lalr1-fusion.cc: this new file.
2095 (b4_rhs_value, b4_rhs_location): New definitions overriding those
2097 (state_stack_type, semantic_stack_type, location_stack_type)
2098 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
2099 (data_type, stack_type, yystack_): New.
2100 (YYLLOC_DEFAULT, yypush_): Adjust.
2101 (yyerror_range): Now based on data_type, not location_type.
2103 2008-11-03 Akim Demaille <demaille@gostai.com>
2105 Push the state, value, and location at the same time.
2106 This is needed to prepare a forthcoming patch that fuses the three
2109 * data/lalr1.cc (parser::yypush_): New.
2110 (parser::yynewstate): Change the semantics: instead of arriving to
2111 this label when value and location have been pushed, but yystate
2112 is to be pushed on the state stack, now the three of them must
2113 have been pushed before. yystate still must be the new state.
2114 This allows to use yypush_ everywhere instead of individual
2115 handling of the stacks.
2117 2008-11-03 Akim Demaille <demaille@gostai.com>
2119 Prefer references to pointers.
2120 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
2121 definition to use references instead of pointers.

2123 Take the value and location as references.
2126 2008-11-03 Akim Demaille <demaille@gostai.com>
2128 stack::size instead of stack::height.
2129 * data/lalr1.cc (stack::height): Rename as...
2130 (stack::size): this.
2131 Fix the output type.
2134 2008-11-03 Akim Demaille <demaille@gostai.com>
2136 Use variants to support objects as semantic values.
2137 This patch was inspired by work by Michiel De Wilde. But he used
2138 Boost variants which (i) requires Boost on the user side, (ii) is
2139 slow, and (iii) has useless overhead (the parser knows the type of
2140 the semantic value there is no reason to duplicate this
2141 information as Boost.Variants do).
2143 This implementation reserves a buffer large enough to store the
2144 largest objects. yy::variant implements this buffer. It was
2145 implemented with Quentin Hocquet.
2147 * src/output.c (type_names_output): New.
2148 (output_skeleton): Invoke it.
2149 * data/c++.m4 (b4_variant_if): New.

2152 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
2153 (b4_char_sizeof, yy::variant): New.
2154 (parser::parse): If variants are requested, define
2155 parser::union_type, parser::variant, change the definition of
2156 semantic_type, construct $$ before running the user action instead
2157 of performing a default $$ = $1.
2158 * examples/variant.yy: New.
2159 Based on an example by Michiel De Wilde.
2161 2008-11-03 Akim Demaille <demaille@gostai.com>
2163 Parameterize the extraction of semantic values.
2164 To make future changes easier, no longer rely on ".TYPE" being the
2165 way to get a semantic value.

2169 * data/c++.m4, data/yacc.c: Use it.

2249 (Java Scanner Interface): Move note on %pure-parser to Java Bison
2250 Interface. Describe %code lexer and yylex accutately.
2251 Remove documentation that does not match the code.
2252 (Java Action Features): New.
2253 (Java Differences): Add reference. Add item on semantic values.
2254 Add note about @{ ... @}. Clarify %% epilogue placement.
2255 (Java Declarations Summary): New.
2258 * data/java.m4 (b4_prefix): Correct quoting for m4_define_default.
2259 (b4_remove_comma): Quote test argument.
2260 (b4_identification): Remove "bison" field.
2261 * tests/java.at (Java parser class and package names): New test.

2278 Always put auxiliary code files in the same dir as other output files.
2279 * src/files.c (compute_file_name_parts): When the user specifies
2280 --output but not --file-prefix, extract the directory prefix from the
2281 file prefix not from the grammar file name. This affects the location
2282 of files like location.hh generated by the C++ skeleton. The includes
2283 in the other output files require this fix.

2369 2008-08-29 Akim Demaille <demaille@gostai.com>
2371 Clarify UPDATED use.
2372 * doc/bison.texinfo: It refers to the last edition of this file,
2373 not to the release date of Bison.
2374 Reported by Joel E. Denny.
2376 2008-08-29 Akim Demaille <demaille@gostai.com>

2464 * data/m4sugar/m4sugar.m4 (changeword): Nuke.
2465 (m4_prepend): Remove, as it is unused and inherently quadratic,
2466 whereas m4_append is linear in newer m4.
2467 (m4_mkstemp): New builtin.
2468 (m4_symbols): Make rename conditional.
2469 (m4_version_prereq): Ensure fatal error if used in bison, which

2519 Fix dependence on computed configure variables.
2520 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not

2523 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2525 2008-07-20 Joel E. Denny <jdenny@ces.clemson.edu>

2546 .prev-version, and .version.
2547 * NEWS (2.3b+): Rename to...
2548 (?.?): ... this because we're dropping the "+" version naming scheme,
2549 but, in general, we still can't be sure of our next release name.
2550 * bootstrap: Add a quick hack to remove from .gitignore the
2551 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
2552 entry. This should really be fixed in gnulib instead.
2553 * bootstrap.conf (gnulib_modules): Add gnumakefile.
2554 * configure.ac (AC_INIT): Set version name by invoking
2555 build-aux/git-version-gen.

2585 Fix some .gitignore and .cvsignore problems.
2586 * bootstrap (insert_sorted_if_absent): Replace all uses with...
2587 (insert_vc_ignore): ... this new function, which prepends `/' to all
2588 .gitignore entries before passing them to insert_sorted_if_absent.
2589 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
2590 .cvsignore files are maintained even though Bison developers run
2591 bootstrap while using Git.
2592 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
2595 * .gitignore (/*.patch *.log log patches applied): Remove, broken and
2596 unneeded. Reported by Eric Blake.

2608 * lib/.gitignore, lib/.cvsignore (/unsetenv.c): Add.
2609 * m4/.gitignore, m4/.cvsignore (/environ.m4): Add.
2611 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
2612 the first argument because it may become position-dependent, and unset
2613 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
2614 Add comments explaining these issues in more detail.
2616 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>
2618 Add .gitignore everywhere based on .cvsignore.

2649 2008-05-23 Joel E. Denny <jdenny@ces.clemson.edu>
2651 * HACKING: Don't say don't mention HACKING in the ChangeLog. We've
2652 been doing it for years.
2653 (Test suite): Mention maintainer-push-check and maintainer-xml-check.
2654 (Release Procedure): Add FIXME about make alpha being unmaintained.
2656 2008-05-13 Joel E. Denny <jdenny@ces.clemson.edu>

2667 2008-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
2669 * HACKING (Release Procedure): translation@iro.umontreal.ca is now
2670 coordinator@translationproject.org.
2672 2008-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
2674 * THANKS: Add Eric Blake.
2676 2008-04-23 Eric Blake <ebb9@byu.net>
2678 Revert prior patch, by working around autoconf regression.
2679 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
2680 ("Output file name: ("): Uncomment test.
2681 ("Output file name: )"): Likewise.
2682 Based on an idea from Noah Misch.
2684 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
2686 Work-around an Autoconf 2.62 AT_SETUP bug that was not present in
2687 2.61. Reported by Juan Manuel Guerrero at
2688 <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
2689 * tests/output.at ("Output file name: ("): Comment out test case for
2691 ("Output file name: )"): Likewise.
2693 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
2695 * GNUmakefile: Update git-version-gen invocation so make dist
2698 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
2700 Update to the current gnulib CVS repository, and fix trigraph handling
2702 * bootstrap: Update gnulib CVS repository URL.
2703 (symlink_to_dir): Encapsulate the code that guarantees the destination
2704 directory exists into...
2705 (check_dst_dir): ... this new function, and...
2706 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
2707 fail when copying files into lib/uniwidth/.
2708 * src/output.c (prepare_symbols): When writing yytname muscles, where
2709 symbol names will be encoded in C-string literals, tell quotearg to
2710 escape trigraphs. This used to be the default in gnulib.
2711 * tests/regression.at (Token definitions): Because of the change in
2712 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
2713 escapes trigraphs in symbol names. Thus, yytname no longer has
2714 trigraphs unnecessarily doubly escaped. Update test case output.
2715 Extend test case to be sure Bison's own error messages will no longer
2716 have trigraphs in symbol names unnecessarily escaped once.
2718 2008-04-20 Joel E. Denny <jdenny@ces.clemson.edu>
2720 Fix make dist infinite loop reported by Juan Manuel Guerrero at

2728 2008-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
2730 * NEWS (2.3a+): Mention that -g now takes an argument.
2731 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
2732 consistency. Update the -g and -x entries now that they take
2733 arguments. Use brackets to indicate optional arguments.
2734 * src/getargs.c (usage): Explain the relationship between arguments of
2735 long and short options more completely. Document --defines and -d

3709 Get rid of broken %no-parser, -n, and --no-parser implementation and
3711 * TODO: Don't mention them.
3712 * doc/bison.1: Likewise.
3713 * doc/bison.texinfo (Decl Summary): Likewise.
3714 (Bison Options): Likewise.
3715 (Option Cross Key): Likewise.
3716 * src/getargs.c (no_parser_flag): Remove global variable.
3717 (usage): Don't print description of -n and --no-parser.
3718 (long_options): Remove --no-parser entry here.
3719 (getargs): Remove -n case in the switch here.
3720 * src/getargs.h (no_parser_flag): Remove extern.
3721 * tests/regression.at (Web2c Actions): Remove comment that mentions
3724 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
3726 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
3727 name user variables starting with `yy'. Just pass NULL instead of a
3728 dummy local &yylval to yypush_parse.
3729 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
3732 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
3734 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
3735 true since it's then always used regardless of whether yyoverflow is
3736 defined. Reported by Christian Burger at
3737 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
3738 * THANKS: Add Christian Burger.
3740 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3741 node names: say "Decl Summary" not "Bison Declaration Summary".
3743 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
3745 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
3746 determine whether this function has already complained about an invalid
3747 value for a %define boolean variable, don't check whether Bison has
3748 ever examined the value. As written, the check was a tautology.
3749 Instead, record and check for this complaint using a separate muscle.
3751 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
3753 Fix push parsing memory leak reported by Brandon Lucia at
3754 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
3755 * THANKS: Add Brandon Lucia.
3756 * data/push.c (yypstate_delete): Free the stack if it was reallocated
3757 but the parse never completed and thus freed it.
3758 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
3759 * tests/testsuite.at: Include push.at.
3760 * test/push.at: New.
3761 (Push Parsing: Memory Leak for Early Deletion): New test case.
3763 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
3765 Improve handling of multiple S/R conflicts in the same state and of S/R
3766 conflicts involving multiple reductions.
3767 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
3768 set for a state here or Bison will abort if it is reassigned on a
3769 later conflicted reduction in the same state.
3770 Similarly, don't finalize and assign the solved conflicts report here
3771 or it will be lost if it is reassigned on a later conflicted reduction
3773 (set_conflicts): Instead, assign them both here after all S/R conflicts
3774 in the state have been fully examined.
3775 * src/print.c (shift_set): Rename to...
3776 (no_reduce_set): ... this.
3777 (print_reductions): Update for rename, and add %nonassoc error action
3778 tokens to no_reduce_set so that, when printing the first remaining
3779 reduction on an error action token, the reduction is enclosed in
3781 (print_results): Update for rename.
3782 * tests/conflicts.at (Solved conflicts report for multiple reductions
3783 in a state): New test case.
3784 (%nonassoc error actions for multiple reductions in a state): New test
3787 * src/main.c (main): Don't depend on C99 features.
3789 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
3791 * build-aux/.cvsignore: Add compile.
3792 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
3795 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
3797 * bootstrap (slurp): Create target directories that don't exist.
3798 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
3800 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
3802 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
3804 * closure.c (closure): Likewise.
3805 * state.h (reductions): Comment sorting of rules.
3806 (state): Comment sorting of items.
3808 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
3810 Fix C++ test cases after recent Gnulib changes. Discussed starting at
3811 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
3812 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
3813 definition in order to avoid Gnulib headers since we don't use config.h
3815 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
3816 rather than AT_DATA so that config.h is included.
3818 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
3820 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
3821 instead of fprintf. Guard these functions with #if YYDEBUG instead of
3822 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
3823 and so that YYFPRINTF is guaranteed to be defined here.
3825 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
3827 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
3829 (muscle_percent_define_check_values): ... this more helpful function.
3830 Again, it's not used yet, but it will be.
3831 * src/muscle_tab.h: Likewise.
3833 Improve some comments in parser table construction.
3834 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
3835 (generate_states): Don't mention ruleset, which is internal to closure.
3836 * src/closure.c (closure): Explain sorting of core and itemset, which
3837 is required for this function to behave correctly.
3838 * src/closure.h (closure): Mention sorting.
3840 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
3842 * src/lalr.c (state_lookahead_tokens_count): For code readability,
3843 move the check for disabled transitions to an aver since conflict
3844 resolution hasn't happened yet.
3846 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3847 labels a state as inconsistent just because it has error transitions.
3848 The original form of this check appeared in revision 1.1 of lalr.c,
3849 which was committed on 1991-12-21. Now (at least), changing the
3850 consistency label on such a state appears to have no useful effect in
3851 any of the places it is examined, which I enumerate below. The key
3852 point to understanding each item in this enumeration is that a state
3853 with an error transition is labelled consistent in the first place only
3854 if it has no rules, so the check cannot matter for states that have
3855 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3856 to try to identify its conflicts, and a state must have *rules* to have
3857 conflicts. (2) Labelling a state as inconsistent will affect how
3858 action_row sets the default *rule* for the state. (3) Labelling a
3859 state as inconsistent will cause build_relations to add lookback edges
3860 to *rules* in that state.
3861 * src/state.h (struct state): Word the comment for member consistent
3864 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
3866 Don't depend on C99 features.
3867 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
3868 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
3869 * src/reader.c (check_and_convert_grammar): Fix for-loop.
3870 * src/state.c (state_mark_reachable_states): Fix for-loop.
3871 (state_remove_unreachable_states): Fix for-loop.
3873 Don't widen struct state with member reachable just to temporarily
3874 record reachability. Instead, use a local bitset.
3875 * src/state.h (struct state): Remove member.
3876 * src/state.c (state_new): Don't initialize it.
3877 (state_mark_reachable_states): Rename to...
3878 (state_record_reachable_states): ... this, and use bitset.
3879 (state_remove_unreachable_states): Use bitset.
3881 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
3883 * src/Makefile.am (yacc): Quote target action commands properly so
3884 that the yacc script isn't corrupt. Reported by Hans Aberg at
3885 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
3887 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
3888 the case of pure parsers. Reported by Frans Englich at
3889 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
3890 * THANKS: Add Frans Englich.
3892 * NEWS (2.3a+): In the %code entry, reference section `Bison
3893 Declaration Summary' from the manual now since the %code summary has
3895 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
3896 in the rules section must be terminated by semicolons.
3898 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
3900 Extend the front-end API for %define variables to more completely
3901 mirror the back-end. This will be useful in the future.
3902 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
3903 Update comments to mention the new front-end counterparts of these
3905 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code

3912 muscle_percent_define_get to mimic the b4_percent_define_flag_if
3913 implementation more closely.
3914 (muscle_percent_define_invalid_value): New function.
3915 * src/muscle_tab.h (muscle_percent_define_get,
3916 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
3919 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
3921 * NEWS (2.3a+): Mention yesterday's state-removal change.
3922 (2.3a): Remove the %language entry, which was added after 2.3a.
3923 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
3924 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
3925 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
3926 tests/existing.at: Update copyright date.
3928 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
3930 If conflict resolution makes states unreachable, remove those states,
3931 report rules that are then unused, and don't report conflicts in those
3933 * src/conflicts.c, src/conflicts.h (conflicts_update_state_numbers):
3934 New global function.
3935 * src/lalr.c, src/lalr.h (lalr_update_state_numbers): New global

3953 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
3954 (new_itemsets, save_reductions): Update for rename to nitemset.
3955 * src/closure.c (nritemset): Rename to...
3956 (nitemset): ... this since the "r" appears to meaningless and isn't
3957 used in the comments.
3958 (closure): Update for rename.
3959 * src/closure.h (nritemset): Update extern to...
3960 (nitemset): ... this.

3966 2007-04-04 Paul Eggert <eggert@cs.ucla.edu>
3968 * THANKS: Use ASCII for Sebastien Fricker's name. Bison source
3969 still sticks to ASCII. Sorry!

4047 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
4048 Bison uses of names rather than just skeleton uses of names.
4049 (b4_percent_define_get, b4_percent_define_ifdef): Rename
4050 b4_percent_define_skeleton_variables(VARIABLE) to
4051 b4_percent_define_bison_variables(VARIABLE).

4056 * src/muscle_tab.c, src/muscle_tab.h (muscle_percent_define_flag_if,
4057 muscle_percent_define_default): New functions mimicking
4058 b4_percent_define_flag_if and b4_percent_define_default.
4060 For %define variables, report locations for invalid values and
4062 * data/bison.m4 (b4_percent_define_flag_if): Read
4063 b4_percent_define_loc(VARIABLE) to report the location of an invalid
4065 (b4_percent_define_default): Save a special location in

4070 (muscle_percent_define_insert): Record the location of VARIABLE in
4071 muscle percent_define_loc(VARIABLE), and use it to report the previous
4072 location for a redefinition.
4073 (muscle_percent_define_flag_if): Update like b4_percent_define_flag_if.
4074 (muscle_percent_define_default): Update like b4_percent_define_default.
4075 (muscle_grow_user_name_list): Rename to...
4076 (muscle_user_name_list_grow): ... this for consistency and use
4077 muscle_location_grow.
4078 * src/muscle_tab.h (muscle_location_grow): Prototype.
4079 * tests/input.at (%define errors): Update expected output.
4080 * tests/skeletons.at (%define boolean variables: invalid skeleton
4081 defaults): New test case.
4083 2007-02-28 Joel E. Denny <jdenny@ces.clemson.edu>
4085 * src/print.c (lookahead_set, state_default_rule): Remove.
4086 (print_reductions): Replace state_default_rule invocation with
4087 equivalent use of yydefact, which was computed in token_actions in
4089 (print_results): Don't allocate lookahead_set.
4091 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
4093 * data/lalr1.java: Prefix all private members with yy.
4095 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
4097 Use YYFPRINTF instead of fprintf where appropriate. Reported by
4098 Sebastien Fricker at
4099 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
4100 * THANKS: Add Sebastien Fricker.
4101 * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
4102 * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must
4103 accept a variable number of arguments.
4105 2007-02-19 Joel E. Denny <jdenny@ces.clemson.edu>
4107 * bootstrap: Remove occurrences of .#bootmp from lib/Makefile.
4109 2007-02-13 Juan Manuel Guerrero <juan.guerrero@gmx.de>
4111 * djgpp/config.bat: Adjustments concerning the use of autoconf 2.61.
4112 * djgpp/config.sed: Adjustments concerning the use of autoconf 2.61.
4113 * djgpp/config.site: Adjustments concerning the use of autoconf 2.61.
4115 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
4117 Undo my 2007-02-07 change, switching back to the c-strcase module
4118 introduced in the 2007-02-03 change. Bruno Haible reported that
4119 the 2007-02-07 change would be dangerous in Turkish if we add a
4120 language whose name contains "i", since "i" is not lowercase "I"
4122 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
4123 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
4124 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
4125 * m4/.cvsignore: Remove strcase.m4.
4126 * src/getargs.c: Revert 2007-02-07 change, as follows.
4127 Include c-strcase.h.
4128 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
4130 2007-02-11 Bruno Haible <bruno@clisp.org>
4132 Enable the Java related testsuite tests when the only Java compiler
4133 found is a gcj < 4.3. Discussed at
4134 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
4135 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
4137 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
4139 * data/Makefile.am: Update copyright date.
4140 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
4141 yypstate_new returns NULL.
4142 (yypstate_new): Return NULL if malloc does.
4143 * src/reader.c (packgram): Move translation of rule actions from the
4144 beginning of packgram to...
4145 (check_and_convert_grammar): ... here right before packgram is invoked
4146 so it's easier to write more complete comments, and remove redundant
4149 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
4151 As in semantic actions, make @$ in %initial-action, %destructor, and
4152 %printer imply %locations.
4153 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
4155 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
4156 (@$ in %initial-action implies %locations,
4157 @$ in %destructor implies %locations,
4158 @$ in %printer implies %locations): ... these new test cases.
4160 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
4162 Undo most of the 2007-02-03 change, switching to the strcase module
4163 now that gnulib strcase has been fixed.
4164 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
4165 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
4166 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
4167 * m4/.cvsignore: Add strcase.m4.
4168 * src/getargs.c: Revert 2007-02-03 change, as follows.
4169 Don't include c-strcase.h.
4170 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
4171 strcasecmp has "unspecified behavior" outside the POSIX locale,
4172 but it works fine in practice if at least one argument is ASCII,
4173 as is the case in Bison.
4175 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
4177 * tests/java.at: Skip tests if only one of javac/java is present.
4178 Reported by Joel E. Denny.
4179 * tests/atlocal.in: Adjust copyright years.
4181 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
4183 * data/lalr1.java (Stack): Work around old verifiers that disallow
4184 access to the private fields of an inner class, from the outer class.
4185 We can make Stack's fields public because user code doesn't have access
4186 to the instance of Stack used by parse(). Reported by Paul Eggert.
4188 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
4190 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
4191 the right spot for these files?
4192 * bootstrap.conf (gnulib_modules): Add c-strcase.
4193 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
4195 * src/getargs.c: Include c-strcase.h.
4196 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
4197 to avoid unspecified behavior.
4199 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
4201 * doc/bison.texinfo (Decl Summary): Correct typo.
4203 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
4205 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
4206 Complain if the value does not match empty, "true" or "false".
4207 * data/c++.m4: Adjust default definitions of %define variables.
4208 * data/java.m4: Adjust default definitions of %define variables.
4209 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
4211 * tests/input.at (Boolean %define variables): Test new behavior.
4213 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
4215 * NEWS: Mention java.
4216 * TODO: Remove things that are done.
4217 * bootstrap.conf: Add javacomp-script and javaexec-script.
4218 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
4220 * data/Makefile.am: Add new files.
4221 * data/java-skel.m4: New.
4222 * data/java.m4: New.
4223 * data/lalr1.java: New.
4225 * doc/bison.texinfo: Put "A Complete C++ Example" under
4226 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
4227 under Other Languages.
4229 * src/getargs.c (valid_languages): Add Java.
4230 * src/getargs.h (struct bison_language): Update size of string fields.
4232 * tests/Makefile.am: Add java.at.
4233 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
4234 * tests/java.at: New.
4235 * tests/testsuite.at: Include it.
4237 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
4240 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
4241 at_directive_argv arguments so these no longer have to be global
4242 variables. Also, update the implementation for the following changes.
4243 (fail_for_at_directive_too_many_args,
4244 fail_for_at_directive_too_few_args): Add at_directive_name argument.
4245 (at_directive_name): Remove as at_directive_argv[0] will be used for
4247 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
4248 for the directive name.
4249 (at_directive_argc, at_directive_argv): Make these local within
4250 skel_lex instead of global.
4251 (INITIAL): Update directive start action for above changes.
4252 (SC_AT_DIRECTIVE_ARG): Rename to...
4253 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
4254 (SC_AT_DIRECTIVE_SKIP_WS): Update.
4255 (scan_skel): Move yylex_destroy to...
4256 (skel_scanner_free): ... here.
4257 * tests/skeletons.at (installed skeleton file name): Rename to...
4258 (installed skeleton file names): ... this.
4260 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
4262 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4263 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
4264 Summary" not "Directives".
4265 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
4266 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
4267 since the former is now the more complete one.
4268 (Prologue Alternatives): Likewise and do the same for %defines.
4269 (Table of Symbols): Add summary of %code, add summary of %define, and
4270 move full %code documentation to...
4271 (Decl Summary): ... here for consistency with other entries in these
4273 Move %define entry in order to keep this list alphabetized.
4274 Reword %define entry a little to put less emphasis on the skeleton
4275 concept, which most users shouldn't have to think about.
4277 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
4279 Adjust to recent gnulib changes.
4280 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
4281 Add string.h, string_.h, unistd_.h, wchar_.h.
4282 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
4283 * src/system.h: Don't include <stpcpy.h>; this is now done by
4286 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
4288 Simplify implementation of unqualified %code, implement macros for
4289 uniform treatment of boolean %define flags. Document %define.
4290 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
4291 b4_percent_code_ifdef): New.
4292 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
4293 * data/c++.m4: Define default value for global_tokens_and_yystype.
4294 * data/glr.cc: Likewise.
4295 * data/location.cc: Use b4_percent_define_flag_if.
4297 * doc/bison.texinfo (Decl Summary): Document %define.
4299 * src/parse-gram.y (Unqualified %code): Change muscle name to
4301 (content.opt): Default to empty.
4303 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
4305 Implement support for relative and absolute skeleton file names.
4306 Discussed starting at
4307 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
4308 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
4309 (Bison Options): Document in --skeleton entry.
4310 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
4311 full_skeleton can't necessarily hold all of pkgdatadir.
4312 If the specified skeleton file name contains a `/', don't prepend
4314 * src/parse-gram.y (prologue_declaration): If the specified skeleton
4315 file name contains a `/', prepend the grammar file directory.
4316 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
4317 * skeletons.at: New file.
4318 (relative skeleton file names): New test case.
4319 (installed skeleton file names): New test case.
4320 * tests/testsuite.at: Include skeletons.at.
4322 * bootstrap: Update copyright to 2007.
4324 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
4326 * bootstrap: Remove occurrences of .#bootmp from the files.
4328 2007-01-17 Akim Demaille <akim@epita.fr>
4330 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
4332 Use per-type %printer.
4334 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
4336 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

4344 2007-01-16 Akim Demaille <akim@epita.fr>
4346 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
4348 (Calc++ Scanner): Exit with failure if we can't open the input
4350 Accept "-" standing for stdin.
4351 (Calc++ Top Level): Print the result only if the parsing was
4354 2007-01-16 Akim Demaille <akim@epita.fr>
4356 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
4358 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
4359 and Joel E. Denny <jdenny@ces.clemson.edu>
4361 Clean up %define and %code implementation in M4 some. Most
4362 importantly, rename all related macros to be in the b4_percent_define
4363 and b4_percent_code namespaces. Also, complete support for `.' in
4364 %define variable names and %code qualifiers.
4365 * data/bison.m4 (b4_check_user_names): Check for special
4366 "SKELETON-NAMESPACE(name)" macros instead of using two nested
4368 (b4_get_percent_define, b4_get_percent_code): Rename to...
4369 (b4_percent_define_get, b4_percent_code_get): ... these.
4370 Extend documentation with examples.
4371 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
4372 b4_percent_define_skeleton_variables and
4373 b4_percent_code_skeleton_qualifiers.
4374 Expect any value for the %define variable `foo' to be stored in the
4375 macro named `b4_percent_define(foo)'; expect any %code blocks for the
4376 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
4377 expect any unqualified %code blocks to be stored in a macro named
4378 `b4_percent_code_unqualified'.
4379 Use m4_indir so that %define variable names and %code qualifiers can
4380 contain `.', which is allowed by the grammar parser.
4381 (b4_percent_define_default): New macro to set a default value for a
4383 (m4_wrap): Update wrapped code, and fix some underquoting.
4384 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
4385 Expect grammar uses of %define variables and %code qualifiers to be
4386 defined in b4_percent_define_user_variables and
4387 b4_percent_code_user_qualifiers.
4388 * data/c++.m4: Use b4_percent_define_default rather than
4389 m4_define_default. Fix some underquoting. Skeleton usage of %define
4390 variable define_location_comparison now implies skeleton usage of
4391 %define variable filename_type.
4392 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4393 data/push.c, data/yacc.c: Update macro names.
4394 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
4397 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
4399 DJGPP specific issues.
4401 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
4402 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
4404 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4406 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
4407 run parsers in all tests so that Valgrind is invoked during
4408 maintainer-check-valgrind.
4409 (Duplicate representation of merged trees): Free all semantic values.
4410 (Duplicated user destructor for lookahead): Likewise.
4412 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4414 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
4415 command-line prefix.
4416 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
4417 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
4418 miss Valgrind messages.
4419 (Exploding the Stack Size with Malloc): Likewise.
4421 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4423 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
4424 locals. Reported by Juan Manuel Guerrero at
4425 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
4426 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
4427 Fix some indentation also.
4428 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
4429 explaining this issue.
4431 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
4432 and Joel E. Denny <jdenny@ces.clemson.edu>
4434 Simplify union and prologue handling, and escape union and lex/parse
4435 params with digraphs.
4436 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
4437 values to the empty string since these are no longer guaranteed
4438 initialized by the front-end.
4439 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
4440 braces around b4_user_stype since this is no longer done by the
4442 * src/files.c, src/files.h (pre_prologue_obstack,
4443 post_prologue_obstack): Remove.
4444 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
4445 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
4446 with digraphs. This fixes lex params and parse params.
4447 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
4448 * src/output.c (prepare): Remove muscle insertion of the prologues.
4449 (output): Remove freeing of pre_prologue_obstack and
4450 post_prologue_obstack.
4451 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
4452 than prologue_augment for prologue parsing so you don't need prologue
4454 (grammar_declaration): For %union RHS, use `braceless' instead of
4455 "{...}" so that braces are already stripped and code is escaped with
4457 * src/reader.c (prologue_augment): Remove.
4458 (reader): Remove initialization of pre_prologue_obstack and
4459 post_prologue_obstack.
4460 * src/reader.h (prologue_augment): Remove.
4462 * data/c.m4: Remove stray parenthesis.
4464 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4466 Remove quotes from variables names in %define directives and from
4467 qualifiers in %code directives, and restrict the characters that are
4468 allowed in them to M4-friendly ones. For %define, continue to support
4469 the quoted form as a deprecated feature. Discussed starting at
4470 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
4471 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
4473 * doc/bison.texinfo (Prologue Alternatives): Update.
4474 (Decl Summary): In %defines entry, update mention of `%code requires'
4475 and `%code provides'.
4476 (C++ Location Values): Update %define uses.
4477 (Calc++ Parser Interface): Likewise.
4478 (Calc++ Parser): Likewise, and update `%code requires' uses.
4479 (Table of Symbols): Update %code documentation.
4480 * src/parse-gram.y (prologue_declaration): For %define variables, use
4481 `variable' instead of `STRING'.
4482 (grammar_declaration): For %code qualifiers, use `ID' instead of
4484 (variable): New nonterminal that takes an `ID' or a `STRING'.
4485 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
4487 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
4488 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
4489 (%define errors): Update %define uses.
4491 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4493 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
4494 instead of muscle_insert for %define values so that M4-special
4495 characters are replaced with digraphs.
4496 * tests/input.at (%define errors): Extend to check weird values.
4498 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4500 Instead of having skeletons declare all valid %define variables and
4501 %code qualifiers, provide macros that retrieve the associated values
4502 and build these lists automatically. Thus Bison will now warn when a
4503 variable or qualifier is not used by the skeleton in the current
4504 invocation regardless of whether it might sometimes be used by that
4505 skeleton in other invocations. Also, move all %define value macros to
4506 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
4507 form, which is replaced by %code.
4508 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
4509 (b4_check_user_names): ... this, and change the series of valid name
4510 arguments to a single list argument for names used in the skeleton
4511 similar to the existing list argument for names used in the grammar.
4512 Warn instead of complaining.
4513 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
4514 values and %code code, to format %code code properly, and to build
4515 lists of all %define variables and %code qualifiers used in the
4516 skeleton: b4_skeleton_percent_define_variables and
4517 b4_skeleton_percent_code_qualifiers.
4518 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
4520 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
4521 the skeleton names lists can finish building first. In place of
4522 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
4523 expect the lists b4_user_percent_define_variables and
4524 b4_user_percent_code_qualifiers.
4525 * data/c++.m4: Where setting default values for b4_parser_class_name,
4526 b4_location_type, b4_filename_type, b4_namespace, and
4527 b4_define_location_comparison, update their names to the
4528 b4_percent_define_ namespace.
4529 * data/glr.c: Don't use b4_check_percent_define_variables and
4530 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4531 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
4532 (b4_parser_class_name, b4_namespace): Define these using
4533 b4_get_percent_define for parser_class_name and namespace.
4534 * data/location.cc: Use b4_get_percent_define.
4535 * data/push.c: Don't use b4_check_percent_define_variables and
4536 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4537 * data/yacc.c: Likewise, and don't call m4_exit in
4538 b4_use_push_for_pull_if or m4_wrap code will never execute.
4539 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
4541 (muscle_grow_user_name_list): ... this for consistency with the
4542 terminology used in bison.m4.
4543 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
4544 %define variable names, and rename muscle used_percent_define_variables
4545 to user_percent_define_variables.
4546 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
4547 user_percent_code_qualifiers.
4549 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
4550 {CODE} form is no longer accepted.
4551 * tests/input.at (Reject bad %code qualifiers): Rename to...
4552 (Reject unused %code qualifiers): ... this, and update test output.
4553 (%define error): Update test output.
4555 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
4557 Check for unrecognized %define variables similar to checking for
4558 unrecognized %code qualifiers. Check for redefined %define variables.
4559 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
4561 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
4562 (b4_check_percent_define_variables): New, also wraps it.
4563 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
4564 variables using b4_check_percent_define_variables.
4565 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
4566 all those exercised in the test suite and all those listed in the
4567 `Default values' section of c++.m4. Are there others?
4568 * data/push.c, data/yacc.c: Declare no valid %define variables.
4569 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
4570 similar to muscle_find, but it works even when the muscle stores a
4572 (muscle_grow_used_name_list): New function for constructing the used
4573 name list muscles that b4_check_for_unrecognized_names requires.
4574 * src/parse-gram.y (prologue_declaration): Warn if a variable is
4575 %define'd more than once. Define the b4_used_percent_define_variables
4576 muscle with muscle_grow_used_name_list.
4577 (grammar_declaration): Abbreviate %code code with
4578 muscle_grow_used_name_list.
4579 * tests/input.at (%define errors): New.
4581 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4583 Provide warn_at, complain_at, and fatal_at function callbacks to the
4584 skeletons, and use this for %code qualifier complaints.
4585 * data/bison.m4 (b4_error_at): New, invoked by...
4586 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
4587 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
4588 @fatal_at(...@) directives.
4589 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
4590 qualifiers in b4_used_percent_code_qualifiers and to use
4592 * src/location.c, src/location.h (boundary_set_from_string): New global
4594 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
4596 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
4597 to b4_used_percent_code_qualifiers.
4598 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
4600 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
4601 (lineno): Rename to...
4602 (out_lineno): ... this so I don't misunderstand it again.
4603 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
4604 here; these newlines are in the input but not the output file.
4605 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
4606 (at_directive_perform): ... this new static function, and add handling
4607 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
4609 * tests/input.at (Reject bad %code qualifiers): Update test output with
4610 locations and extend.
4612 * tests/output.at (Output file name: [, Output file name: ]): Remove
4613 bogus comment about these tests failing.
4615 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4617 Clean up b4_check_percent_code_qualifiers a little.
4618 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
4619 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
4620 documentation and add examples.
4621 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
4624 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
4626 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
4627 unreliable -- especially when they're hidden inside another macro.
4628 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
4629 data/c.m4: Remove m4_divert(-1).
4630 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4631 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
4632 m4_divert_push(0) and m4_divert_pop(0).
4633 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
4634 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
4635 pushed and popped by m4sugar, should be first on the stack.
4637 Provide warn, complain, and fatal function callbacks to the skeletons.
4638 This provides more flexibility than m4_fatal, improves the error
4639 message format, and captures messages for translation. Discussed
4641 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
4642 * data/bison.m4 (b4_error): New, invoked by...
4643 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
4644 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
4645 directives. Because these M4 macros might be called when the current
4646 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
4647 the previous removal of uses of m4_divert, which caused trouble.
4648 (b4_check_percent_code_qualifiers): Use b4_complain instead of
4649 m4_fatal to report unrecognized %code qualifiers.
4650 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
4651 push parser requests.
4652 * data/glr.c: Use b4_complain instead of m4_fatal to report
4653 non-deterministic push parser requests.
4654 Update @output usage to @output(...@) form.
4655 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
4656 report missing %defines. Update @output usage to @output(...@) form.
4657 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
4659 * src/main.c (main): Invoke skel_scanner_free.
4660 * src/scan-skel.h (skel_scanner_free): Prototype new function.
4661 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
4662 obstack_for_string from flex-scanner.h.
4663 (YY_DECL): Use to declare skel_lex static.
4664 (decode_at_digraphs): Remove; now handled in the new
4665 SC_AT_DIRECTIVE_ARG start condition.
4666 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
4668 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
4669 at_directive_argv): New static globals.
4670 (INITIAL): Use fail_for_invalid_at.
4671 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
4672 recognize the start of a generalized `@directive(...@)' form and
4674 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
4675 directive args (using the new obstack_for_string), to decode the
4676 contained @ diagraphs, and to perform the directive. It recognizes
4677 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
4679 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
4680 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
4682 (scan_skel): Initialize obstack_for_string on the first call.
4683 (skel_scanner_free): New function to free obstack_for_string.
4684 * tests/input.at (Reject bad %code qualifiers): Update test output.
4686 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
4688 Consolidate the 4 prologue alternative directives (%code, %requires,
4689 %provides, and %code-top) into a single %code directive with an
4690 optional qualifier field. Discussed at
4691 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
4692 * NEWS (2.3a+): Rewrite the existing entry for the prologue
4694 * doc/bison.texinfo (Prologue Alternatives): Update.
4695 (Decl Summary): Update to %code "requires" and %code "provides".
4696 (Calc++ Parser): Update to %code "requires".
4697 (Table of Symbols): Remove entries for %requires, %provides, and
4698 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
4699 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
4700 are replaced by b4_percent_code_provides and b4_percent_code_requires,
4701 which are skeleton-specific.
4702 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
4703 declare what %code qualifiers it supports and to complain if any other
4704 qualifiers were used in the grammar.
4705 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
4706 and b4_user_code([b4_percent_code_provides]) in place of
4707 b4_user_requires and b4_user_provides.
4708 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
4709 Add b4_user_code([b4_percent_code_top]) and
4710 b4_user_code([b4_percent_code]).
4711 Invoke b4_check_percent_code_qualifiers.
4712 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4713 PERCENT_REQUIRES): Remove.
4714 (grammar_declaration): Remove RHS's for %code-top, %provides, and
4715 %requires. Rewrite the %code RHS as the unqualified form defining the
4716 muscle b4_percent_code. Add another RHS for the qualified %code form,
4717 which defines muscles of the form b4_percent_code_QUALIFIER and the
4718 b4_used_percent_code_qualifiers muscle.
4719 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4720 PERCENT_REQUIRES): Remove.
4721 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
4722 %code "requires" and %code "provides".
4723 * tests/input.at (Reject bad %code qualifiers): New.
4725 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4727 Use the new code_props interface for destructors and printers.
4728 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
4729 printer_location members, and change the type of the destructor and
4730 printer members to code_props.
4731 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
4732 symbol_printer_get, semantic_type_destructor_set,
4733 semantic_type_printer_set, default_tagged_destructor_set,
4734 default_tagless_destructor_set, default_tagged_printer_set,
4735 default_tagless_printer_set): Use code_props in arguments and return
4736 types in place of char const * and location.
4737 (symbol_destructor_location_get, symbol_printer_location_get): Remove
4738 since the locations are now contained in the return of
4739 symbol_destructor_get and symbol_printer_get.
4740 * src/output.c (symbol_destructors_output, symbol_printers_output):
4742 (symbol_code_props_output): ... this to eliminate duplicate code.
4743 (output_skeleton): Update to use symbol_code_props_output.
4744 * src/reader.c (symbol_should_be_used): Update use of
4745 symbol_destructor_get.
4746 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4747 Update uses of the various _destructor_set and _printer_set functions.
4748 * src/symtab.c: (default_tagged_destructor_location,
4749 default_tagless_destructor_location, default_tagged_printer_location,
4750 default_tagless_printer_location): Remove since we...
4751 (default_tagged_destructor, default_tagless_destructor,
4752 default_tagged_printer, default_tagless_printer): ... change the type
4753 of these to code_props.
4754 (symbol_new, semantic_type_new, symbol_destructor_set,
4755 semantic_type_destructor_set, symbol_destructor_get,
4756 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
4757 symbol_check_alias_consistency, default_tagged_destructor_set,
4758 default_tagless_destructor_set, default_tagged_printer_set,
4759 default_tagless_printer_set): Update.
4760 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
4761 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
4763 (symbol_print): Use SYMBOL_CODE_PRINT.
4765 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4767 Use the new code_props interface for rule actions.
4768 * src/symlist.h (symbol_list): Replace action, action_location, and
4769 used members with a code_props action_props member.
4770 * src/reader.c (symbol_should_be_used, grammar_rule_check,
4771 grammar_midrule_action, grammar_current_rule_merge_set,
4772 grammar_current_rule_symbol_append, packgram): Update.
4773 * src/scan-code.h (translate_rule_action): Remove, no longer used.
4774 * src/scan-code.l (handle_action_dollar): Update.
4775 (translate_rule_action): Remove, no longer used.
4776 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
4778 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4780 Use the new code_props interface in parse-gram.y.
4781 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
4782 Update all uses of translate_* functions to use the new code_props
4783 interface and to use gram_scanner_last_string_free and
4784 code_scanner_last_string_free where possible.
4785 (grammar_declaration): symbol_list_destructor_set and
4786 symbol_list_printer_set now perform the translation, so don't do it
4787 here. Use gram_scanner_last_string_free where possible.
4788 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
4789 translate_code): Remove, no longer used.
4790 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
4791 symbol_list_printer_set): Perform code translation here rather than
4792 depending on the caller to do so.
4794 * src/symlist.h (struct symbol_list): Correct some documentation typos.
4795 * src/scan-gram.h (gram_last_string): Remove declaration.
4796 * src/scan-gram.l (last_string): Declare it static.
4798 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4800 Encapsulate code properties and related functionality for the various
4801 destructors, printers, and actions into a code_props structure and
4802 interface. This patch merely implements code_props in scan-code.h and
4803 scan-code.l. Future patches will rewrite other modules to use it.
4804 Discussed starting at
4805 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
4806 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
4807 consistently initialize const structs that have an empty location
4809 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
4810 to ensure consistency.
4811 * src/scan-code.h (code_props): New structure.
4812 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
4813 function, macro, and const global variable for initializing a
4814 code_props with no code.
4815 (code_props_plain_init, code_props_symbol_action_init,
4816 code_props_rule_action_init, code_props_translate_code): The rest of
4817 the new code_props functional interface. Among other things, the init
4818 functions set the code_props kind field so that
4819 code_props_translate_code will know whether to behave like
4820 translate_symbol_action, translate_rule_action, or translate_code.
4821 These old translate functions must remain until all other modules are
4822 updated to use the new code_props interface.
4823 (code_scanner_last_string_free): New function similar to
4824 gram_scanner_last_string_free.
4825 (code_scanner_free): Add documentation.
4826 * src/scan-code.l: Implement the new interface.
4827 (code_lex): Make it static, add a code_props* argument, and remove the
4829 (last_string): New static global similar to the one in scan-gram.l.
4830 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
4832 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
4833 code_props since Bison may one day use this information for destructors
4835 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
4836 (handle_action_dollar): Use symbol_list_n_get and set used flag
4837 directly since symbol_list_n_used_set is removed.
4838 (translate_action): Add a code_props* argument and remove the rule,
4839 action, and location arguments. Pass the code_props* on to code_lex.
4840 (translate_rule_action, translate_symbol_action, translate_code):
4841 Rewrite as wrappers around the new code_props interface.
4842 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
4843 it would eventually need to break the encapsulation of code_props.
4845 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4847 * etc/.cvsignore: New.
4849 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4851 Add maintainer-push-check to run maintainer-check using push parsing in
4852 place of pull parsing where available.
4853 * Makefile.am (maintainer-push-check): New.
4854 * data/bison.m4 (b4_use_push_for_pull_if): New.
4855 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
4856 appropriately based on their existing values.
4857 (yypush_parse): Don't print push-parser-specific diagnostics if push
4858 parsing is being used in place of pull parsing.
4859 * data/yacc.c: If push parsing should replace pull parsing, redirect to
4861 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
4862 variable, and insert b4_use_push_for_pull_flag into muscles.
4863 * tests/Makefile.am (maintainer-push-check): New.
4865 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4867 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
4868 (whether successful or failed) so that yypush_parse can be invoked
4869 again to start a new parse using the same yypstate.
4870 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
4871 check multiple yypull_parse invocations on the same yypstate. For pull
4872 mode, extend to check multiple yyparse invocations.
4873 (Exploding the Stack Size with Alloca): Extend to try with
4875 (Exploding the Stack Size with Malloc): Likewise.
4877 * tests/calc.at (Simple LALR Calculator): Don't specify
4878 %skeleton "push.c" since %push-pull-parser implies that now.
4879 * tests/headers.at (export YYLTYPE): Don't check for the push
4880 declarations. Otherwise, this test case can't be used to see if push
4881 mode can truly emulate pull mode.
4882 * tests/input.at (Torturing the Scanner): Likewise.
4883 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
4884 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
4885 AT_YACC_IF, which now includes the case of push mode since %skeleton
4886 need not be used for push mode. This will be more intuitive once
4887 push.c is renamed to yacc.c.
4889 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4891 For push mode, convert yyparse from a macro to a function, invoke yylex
4892 instead of passing a yylexp argument to yypull_parse, and don't
4893 generate yypull_parse or yyparse unless %push-pull-parser is declared.
4894 Discussed starting at
4895 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
4896 * data/bison.m4 (b4_pull_if): New.
4897 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
4898 * data/push.c: Improve M4 quoting a little.
4899 (b4_generate_macro_args, b4_parenthesize): Remove.
4900 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
4901 any time a pull parser is requested.
4902 Don't #define this as a wrapper around yypull_parse. Instead, when
4903 both push and pull are requested, make it a function that does that
4905 (yypull_parse): If there's a b4_prefix, #define this to
4906 b4_prefix[pull_parse] when both push and pull are requested.
4907 Don't define this as a function unless both push and pull are
4909 Remove the yylexp argument and hard-code yylex invocation instead.
4910 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
4912 * src/getargs.c (pull_parser): New global initialized to true.
4913 * getargs.h (pull_parser): extern it.
4914 * src/output.c (prepare): Insert pull_flag muscle.
4915 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
4916 (prologue_declaration): Set both push_parser and pull_parser = true for
4917 %push-pull-parser. Set push_parser = true and pull_parser = false for
4919 * src/scan-gram.l: Don't accept %push_parser as an alternative to
4920 %push-parser since there's no backward-compatibility concern here.
4921 Scan %push-pull-parser.
4922 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
4923 instead of %push-parser.
4924 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
4925 prototype it in the module that calls yyparse.
4926 * tests/input.at (Torturing the Scanner): Likewise.
4927 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
4929 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
4931 Update etc/bench.pl. Optimize push mode a little (the yyn change
4932 deserves most of the credit).
4933 * Makefile.am (SUBDIRS): Add etc subdirectory.
4934 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
4935 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
4936 yytoken, yyval, and yyloc declarations to...
4937 (yyparse or yypush_parse): ... here to improve performance. For
4938 yypush_parse invocations after the first, be sure to assign yyn its old
4940 (yypstate_new): Don't bother initializing the yyresult field since the
4941 initial value isn't used.
4942 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
4943 remove the #define that, in push mode, set it to yyps->NAME.
4944 * etc/Makefile.am: New.
4945 * etc/bench.pl: Remove and build it instead from...
4946 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
4947 "tests/bison" from the build directory by default rather than just
4948 invoking "bison" from $PATH.
4949 (calc_grammar): Update push parser code: don't declare yylval globally,
4950 don't define yyparse_wrapper, and don't #define yyparse.
4951 (bench_grammar): Update to check all working combinations of yacc.c,
4952 push.c, impure, pure, pull, and push.
4954 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4956 For push mode, add pull wrappers around yypush_parse.
4957 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
4958 (yypull_parse): New function wrapping yypush_parse.
4959 (yyparse): New #define wrapping yypull_parse.
4960 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
4962 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
4963 prototype yylex in the module that calls yyparse, and don't prototype
4964 yyparse there. Otherwise, the yyparse expansion won't compile.
4965 * tests/input.at (Torturing the Scanner): Likewise.
4967 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4969 Enable push parsers to operate in impure mode. Thus, %push-parser no
4970 longer implies %pure-parser. The point of this change is to move
4971 towards being able to test the push parser code by running the entire
4972 test suite as if %push-parser had been declared.
4973 * data/push.c (yypush_parse): For impure mode, remove the
4974 yypushed_char, yypushed_val, and yypushed_loc arguments.
4975 Instead, declare these as local variables initialized to the global
4976 yychar, yylval, and yylloc.
4977 For the first yypush_parse invocation only, restore the initial values
4978 of these global variables when it's time to read a token since they
4979 have been overwritten.
4980 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
4982 * tests/calc.at (Simple LALR(1) Calculator): Always declare
4983 %pure-parser along with %push-parser since this test case was designed
4984 for pure push parsers.
4985 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
4986 (AT_YACC_OR_PUSH_IF): New.
4987 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
4988 add a note that it's still wrong for some cases (as it has been for a
4990 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
4991 %push-parser no longer implies %pure-parser.
4993 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4995 Remove some unnecessary differences between the pull parser code and
4996 the push parser code. This patch enables yynerrs in push mode.
4997 * data/push.c: Reformat M4 a little.
4998 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
4999 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
5000 because push mode is on. Instead, if pure mode is on, move yynerrs
5002 (b4_declare_parser_state_variables): ... here.
5003 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
5004 to yyps->NAME so it can be used in yypush_parse.
5005 (yypush_parse): Don't omit uses of yynerrs in push mode.
5007 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5009 Fix bug such that the first pushed token's value and location are
5010 sometimes overwritten (sometimes by %initial-action) before being used.
5011 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
5012 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
5013 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
5014 more closely mimic the pull parser logic.
5015 Don't copy the pushed token to yychar, yylval, and yylloc until it's
5016 time to read a token, which is after any initialization of yylval and
5018 (gottoken): Rename label to...
5019 (yyread_pushed_token): ... for clarity and to avoid infringing on the
5022 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
5024 Rearrange initialization of the parser state variables so that the
5025 skeleton doesn't have to have a copy for pull mode and another for push
5026 mode. This patch also fixes at least a bug such that yylloc was not
5027 initialized (with b4_location_initial_line and
5028 b4_location_initial_column) upon calling yypush_parse. However, that
5029 initialization now overwrites the first token's location;
5030 %initial-action assigning @$ already did the same thing, and both bugs
5031 will be fixed in a later patch.
5032 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
5033 (b4_declare_parser_state_variables): Remove initialization of yytoken,
5034 yyss, yyvs, yyls, and yystacksize.
5035 (yypstate_new): Remove initialization of some yypstate fields: yystate,
5036 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
5038 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
5039 yyps->NAME so it can be used in yypush_parse.
5040 (yyparse or yypush_parse): For yypush_parse, don't print the
5041 "Starting parse" diagnostic for invocations after the first.
5042 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
5043 yypush_parse, only do it for the first invocation.
5044 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
5045 initialization to occur in yypush_parse but only on the first
5048 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5050 * data/push.c: Add CPP guards around push parser declarations in both
5051 the header and the code file.
5052 In the code file, move the push parser declarations to the same place
5053 they appear in the header file.
5054 Clean up the M4 some, especially the inconsistent underquoting in
5055 some b4_c_function_def and b4_c_function_decl uses.
5057 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5059 Encapsulate the push parser state variables into an M4 macro so the
5060 push skeleton doesn't have to list them again for pull mode's yyparse.
5061 For push mode, remove yypush_parse's local equivalents of these
5062 variables to eliminate unnecessary copying between the two sets at
5063 run-time. This patch also fixes at least a bug related to multiple
5064 %initial-action invocations in push mode.
5065 * data/push.c (b4_declare_parser_variables): Rename to...
5066 (b4_declare_scanner_communication_variables): ... this for clarity and
5068 (b4_declare_yyparse_variables): Remove and move its contents to the one
5069 spot where it was invoked.
5070 (b4_declare_parser_state_variables): New macro containing the parser
5071 state variables required by push mode.
5072 (struct yypstate): Replace all fields but yynew with
5073 b4_declare_parser_state_variables.
5074 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
5075 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
5076 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
5077 (yyparse or yypush_parse): For yyparse in pull mode, replace local
5078 parser state variable declarations with
5079 b4_declare_parser_state_variables.
5080 Don't initialize parser state variables when calling yypush_parse since
5081 yypstate_new already does that.
5082 Invoke the user's initial action only upon the first yypush_parse
5084 Remove all code that copies between the local parser state variables
5087 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5089 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
5090 prevent a name collision in a future patch where these names will
5091 sometimes be #define'd.
5092 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
5093 since it no longer has the same name as the existing argument.
5094 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
5096 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
5097 and Joel E. Denny <jdenny@ces.clemson.edu>
5099 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
5100 that the argument is case-insensitive, and there's no `=' here.
5101 For the %skeleton entry, mention that %language is better.
5102 (Bison Options): Likewise for --language and --skeleton. Move the
5103 --skeleton entry so that the `Tuning the parser' section is sorted
5104 alphabetically on long options.
5105 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
5106 %language directive in detail here; cross-reference the %language
5107 documentation instead.
5108 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
5109 `%require "2.3b"' so that the example is always up-to-date.
5110 (Table of Symbols): Add entries for %language and %skeleton.
5111 * examples/extexi (normalize): Instead of replacing every %require
5112 argument with the current Bison version, just substitute for
5113 `@value{VERSION}'. This guarantees that we're testing what actually
5114 appears in the documentation.
5115 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
5116 rather than `@VERSION@'.
5118 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5120 * NEWS: Reword the %language news a bit, and put it earlier.
5122 * src/getargs.c (skeleton_arg): Last arg is now location const *.
5123 Rewrite to simplify the logic.
5124 (language_argmatch): Likewise.
5125 (program_name): We now own this var.
5126 * src/getargs.h (struct bison_language): Use char[] rather than
5129 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
5131 * src/complain.c (program_name): Remove decl; no longer needed.
5132 * src/main.c (program_name): Remove; now belongs to getargs.
5134 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
5136 * NEWS: Document %language.
5138 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
5140 * data/c-skel.m4, data/c++-skel.m4: New files.
5141 * data/glr.c: Complain on push parsers.
5143 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
5145 (Decl Summary): Document %language and %skeleton.
5146 (Command line): Document -L.
5148 * examples/extexi: Rewrite %require directive.
5149 * examples/calc++/Makefile.am: Pass VERSION to extexi.
5151 * src/files.c (compute_exts_from_gc): Look in language structure
5153 (compute_file_name_parts): Check whether .tab should be added.
5154 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
5155 (language, skeleton_arg, language_argmatch): New.
5156 (long_options): Add --language.
5157 (getargs): Use skeleton_arg, add -L/--language.
5158 * src/getargs.h: Include location.h.
5159 (struct bison_language, language, skeleton_arg, language_argmatch): New.
5160 * src/output.c (prepare): Pick default skeleton from struct language.
5161 Don't dispatch C skeletons here.
5162 * src/parse-gram.y (PERCENT_LANGUAGE): New.
5163 (prologue_declaration): Add "%language" rule, use skeleton_arg.
5164 * src/scan-gram.l ("%language"): New rule.
5166 * tests/calc.at: Test %skeleton and %language.
5167 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
5168 (AT_GLR_IF): Look for %skeleton "glr.cc".
5169 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
5170 (AT_YACC_IF): Reject %language.
5172 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5174 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
5175 since it wasn't used; only the typedef name 'semantic_type' is needed.
5176 Also, omit trailing white space.
5178 * bootstrap: Sync from coreutils.
5179 (gnulib_extra_files): Add build-aux/announce.gen.
5180 (slurp): Adjust .gitignore files like .cvsignore files.
5181 * build-aux/announce-gen: Remove from CVS, since bootstrap
5184 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
5186 Make %push-parser imply %pure-parser. This fixes several bugs; see
5187 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
5188 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
5190 * data/push.c: Don't bother testing b4_push_if when deciding whether
5191 to expand b4_declare_parser_variables globally.
5192 (yypush_parse): Likewise in here.
5194 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
5195 (yy_reduce_print): Reformat M4 for readability.
5197 2006-12-15 Bob Rossi <bob@brasko.net>
5198 and Joel Denny <jdenny@ces.clemson.edu>
5200 * data/push.c (yypstate): Add typedef, and update all uses of
5201 struct yypstate to just yypstate.
5202 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
5204 2006-12-14 Bob Rossi <bob@brasko.net>
5206 * data/push.c (yypush_parse): Declare prototype regardless of
5209 2006-12-14 Bob Rossi <bob@brasko.net>
5211 * data/push.c (yyparse): Remove the prototype and the #define when in
5214 2006-12-13 Bob Rossi <bob@brasko.net>
5216 * data/push.c (yypstate_init): Rename to...
5217 (yypstate_new): ... this and use b4_c_function_def.
5218 (yypstate_delete): New.
5219 (yypush_parse): Change parameters yynval and yynlloc to be const.
5220 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
5221 yypstate_delete functions.
5223 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
5225 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
5226 strange test case titles. Reported by Bob Rossi.
5228 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
5230 * TODO: Add pointer to Sylvain Schmitz's work on static detection
5231 of potential ambiguities in GLR grammers.
5233 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
5235 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
5236 `bison ', use m4_index instead of m4_substr since chopping up a string
5237 containing M4-special characters causes problems here.
5239 Fix a couple of bugs related to special characters in user-specified
5240 file names, and make it easier for skeletons to compute output file
5241 names with the same file name prefix as Bison-computed output file
5243 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
5244 b4_parser_file_name and b4_spec_defines_file instead of
5245 @output_parser_name@ and @output_header_name@, which are now redundant.
5246 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
5247 b4_parser_file_name, b4_spec_defines_file, and the new
5248 @basename(FILENAME@) instead of @output_parser_name@ and
5249 @output_header_name@, which inappropriately escaped the file names as
5251 * src/files.c (all_but_ext): Remove static qualifier.
5252 (compute_output_file_names): Move `free (all_but_ext)' to...
5253 (output_file_names_free): ... here since all_but_ext is needed later.
5254 * src/files.h (all_but_ext): Extern.
5255 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
5256 exactly what MUSCLE_INSERT_STRING used to do.
5257 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
5258 characters are escaped properly.
5259 * src/output.c (prepare): Define muscle file_name_all_but_ext as
5261 For pkgdatadir muscle, maintain previous functionality by using
5262 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
5263 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
5264 digraphs would never be expanded. Hopefully no one has M4-special
5265 characters in his Bison installation path.
5266 * src/scan-skel.l: Don't parse @output_header_name@ and
5267 @output_parser_name@ anymore since they're now redundant.
5268 In @output, use decode_at_digraphs.
5269 Parse a new @basename command that invokes last_component.
5270 (decode_at_digraphs): New.
5271 (BASE_QPUTS): Remove unused.
5272 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
5273 (Output file name): New tests.
5275 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
5277 Warn about output files that are generated by the skeletons and that
5278 conflict with other output files.
5279 * data/glr.c: Don't generate the header file here when glr.cc does.
5280 * src/files.c (file_names, file_names_count): New static globals.
5281 (compute_output_file_names): Invoke output_file_name_check for files
5282 not generated by the skeletons and remove existing checks.
5283 (output_file_name_check): New function that warns about conflicting
5285 (output_file_names_free): Free file_names.
5286 * src/files.h (output_file_name_check): Declare.
5287 * src/scan-skel.l: Invoke output_file_name_check for files generated by
5289 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
5290 (Conflicting output files): New tests.
5292 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5294 * doc/bison.texinfo: Fix a couple of typos.
5296 2006-12-08 Bob Rossi <bob@brasko.net>
5298 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
5300 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
5302 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
5303 (yypush_parse): Rename yypvars argument to yyps and remove redundant
5305 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
5306 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
5308 2006-12-07 Bob Rossi <bob@brasko.net>
5309 and Joel Denny <jdenny@ces.clemson.edu>
5311 * data/push.c (yypvarsinit): Change return type from void* to struct
5312 yypvars*. No longer cast to void* on return.
5313 (struct yypvars): Remove yylen since it need not be remembered between
5314 yypushparse invocations.
5315 (yypushparse): Don't copy between yylen and pv->yylen.
5317 2006-12-05 Bob Rossi <bob@brasko.net>
5319 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
5320 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
5321 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
5322 (struct yypvars): Remove b4_declare_parser_variables.
5323 (yypvarsinit): Remove init code for removed variables.
5324 (global scope): Do not declare b4_declare_parser_variables if
5326 (yypushparse): Add b4_declare_parser_variables.
5327 Init new local variables, and remove init code for removed
5330 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
5331 and yyparse for other modes.
5332 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
5333 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
5334 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
5335 (AT_PURE_LEX_IF): True if pure or push parser.
5337 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
5339 Document Yacc prologue alternatives and default %destructor's and
5340 %printer's as experimental. Don't mention Java yet. Discussed at
5341 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.
5342 * NEWS (2.3a+): Say they're experimental. Remove any mention of Java.
5343 (2.3a): Annotate this entry to say the old forms of these features were
5345 * doc/bison.texinfo (Prologue Alternatives, Freeing Discarded Symbols,

5421 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
5422 * src/scan-code.l (translate_action): Don't bother invoking
5423 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
5424 (code_scanner_free): Instead of invoking
5425 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

5433 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
5434 has been called previously for the same key.
5435 (muscle_find): Return storage instead of value so that
5436 --enable-gcc-warnings doesn't produce warnings that the return discards
5437 const. aver that the value and storage are the same since storage
5438 could potentially be NULL when value is not.
5439 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
5442 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
5444 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
5445 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
5446 us a slightly cleaner distribution, and also works.
5447 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
5450 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
5451 and Paul Eggert <eggert@cs.ucla.edu>

5454 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
5455 (spec_defines_file, dir_prefix): Now char *, not const char *,
5456 since they are freed.
5457 * src/files.c: Likewise.
5458 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
5460 (tr): Now operates in-place. All uses changed.

5463 (compute_file_name_parts, compute_output_file_names): Don't store
5464 read-only data in variables that will be freed.
5465 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
5466 src_extension, and header_extension.

5475 * src/muscle_tab.c: Likewise.
5476 (muscle_entry): Make the value char const *,
5477 and add a new storage member that is char * and can be freed.

5480 (muscle_insert, muscle_grow): Update and use new storage member.
5481 (muscle_code_grow): Free the string passed to muscle_grow
5482 since it's not needed anymore.
5483 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
5484 add a new `char *code' member.
5485 ("{...}"): Declare semantic type as code.
5486 * src/scan-code.h (translate_rule_action):
5487 (translate_symbol_action, translate_code, translate_action): Return
5488 `char const *' rather than `char *' since external code should not free
5490 * src/scan-code.l: Likewise.
5491 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
5492 which is "{...}" in the parser.
5493 * tests/Makefile.am (maintainer-check-valgrind): Set
5494 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
5496 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
5498 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
5499 expecting a non-zero exit status sets --leak-check=summary and
5500 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
5501 this case, and we don't want to hear about it.
5503 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
5505 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
5506 instead of from the template, to simplify configuration a bit.

5522 declarations): Run tests with and without --warnings=midrule-values.
5524 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
5525 than LIST_FREE directly.
5527 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

5546 empty subargument list. For example: `bison --warnings= parser.y'.
5548 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
5550 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
5551 the parser header file so that gcc doesn't warn.
5553 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>

5601 Don't apply the default %destructor/%printer to an unreferenced midrule
5603 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
5604 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
5605 like $@n instead of just @n so that the default %destructor/%printer
5606 logic doesn't see them as user-defined symbols.
5607 (symbol_is_dummy): Check for both forms of the name.
5608 * src/reader.c (packgram): Remove the `$' from each midrule symbol
5609 name for which the midrule value is referenced in any action.

5620 (packgram): Before invoking grammar_rule_check on any rule, make sure
5621 all actions have already been scanned in order to set `used' flags.
5622 Otherwise, checking that a midrule's $$ is set will not always work
5623 properly because the midrule check must forward-reference the midrule's

5707 Fix testsuite for ./configure --enable-gcc-warnings:
5708 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
5709 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in

5745 * tests/local.at (AT_DATA_GRAMMAR_PROLOGUE):
5746 Include <config.h> unconditionally.
5748 * bootstrap: Sync from coreutils, as follows:
5750 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
5752 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
5753 variable was sometimes used without being initialized. This
5754 messed up the installation of the INSTALL file in some cases.
5756 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
5758 * bootstrap (usage, main program, symlink_to_gnulib): Add option
5759 --copy. Inspired by a suggestion from Bruno Haible.
5761 2006-10-03 Jim Meyering <jim@meyering.net>
5763 * bootstrap: Undo last change to this file, since now gnulib-tool
5764 sticks with the automake default in generating dependencies.
5766 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
5768 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

5805 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.
5806 (b4_yyssa, b4_yyerror_range): New macros.
5807 (struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
5808 (yypvarsinit): Remove init of removed fields.
5809 (yypushparse): Remove use of removed fields; use new macros instead.
5811 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
5813 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
5814 in a push parser. Reindent slightly to match yacc.c better.
5816 2006-10-11 Bob Rossi <bob@brasko.net>
5818 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
5820 (yypvarsinit, yypushparse): Remove init of removed fields.

5823 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
5825 * THANKS: Add Paolo Bonzini and Bob Rossi.
5827 2006-10-08 Paolo Bonzini <bonzini@gnu.org>
5829 * data/c.m4 (b4_copyright, b4_epilogue, b4_location_initial_column,
5830 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
5831 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
5832 b4_define_user_cde and uses): Remove.
5833 (b4_comment, b4_prefix, b4_sync_start): New.
5834 * data/bison.m4: New file, with most of the content removed from c.m4.
5835 * src/muscle_tab.h: Use "do {...} while(0)" throughout.
5836 * src/output.c (output_skeleton): Pass bison.m4.
5837 (prepare): Pass glr_flag and nondeterministic_flag. Pass prefix
5840 2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
5842 Fix test failure reported by Tom Lane in
5843 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
5844 and try to make such failures easier to catch in the future.
5845 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
5846 that's now the caller's responsibility.
5847 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
5848 Set yychar = YYEOF if it's negative.
5849 * tests/actions.at (yylex): Abort if asked to read past EOF.
5850 * tests/conflicts.at (yylex): Likewise.
5851 * tests/cxx-type.at (yylex): Likewise.
5852 * tests/glr-regression.at (yylex): Likewise.
5853 * tests/input.at (yylex): Likewise.
5854 * tests/regression.at (yylex): Likewise.
5855 * tests/torture.at (yylex): Likewise.
5857 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
5859 Fix problems with translating English-language diagnostics.
5860 * bootstrap: Fix bug introduced in recent bootstrap changes, with
5861 respect to bison-runtime pot generation. The YY_ stuff
5862 wasn't being captured.
5863 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
5864 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
5865 * runtime-po/POTFILES.in: Add data/push.c.
5867 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
5869 Merge bootstrap changes from coreutils.
5871 2006-09-28 Jim Meyering <jim@meyering.net>
5873 Automatically generated dependencies are important even
5874 when all of the sources in a directory come from gnulib.
5875 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
5876 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
5878 2006-09-23 Jim Meyering <jim@meyering.net>
5880 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
5882 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5884 * bootstrap: Add support for --force.
5885 (usage): New function. Describe usage less tersely.
5886 (CVS_only_file): New var.
5888 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
5890 * data/push.c (YYPUSH_MORE): Make it an enum instead.
5891 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
5892 Adjust white space and comments to match GNU style better.
5894 2006-09-20 Bob Rossi <bob@brasko.net>
5896 * data/push.c (yyresult_get): Remove function.
5897 (YYPUSH_MORE): Add #define.
5898 (yypushparse): Modify return value.
5900 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5902 * stamp-h.in: Remove; no longer needed.
5903 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
5904 Remove config.h, config.hin, intl (no longer created).
5905 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
5908 Sync bootstrap from coreutils, as follows:
5910 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
5912 * bootstrap (symlink_to_gnulib): New function.
5913 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
5914 to copies-of-gnulib.
5915 (cp_mark_as_generated, slurp, gnulib_files):
5916 Avoid making a copy if it's the same as the old version.
5917 (gnulib_files): Add support for this variable (used by Bison).
5919 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5921 * src/getargs.c (usage): Rework to use conventions similar to
5922 coreutils, to make translation a bit easier and the code a bit
5923 smaller. Problem reported by Tim Van Holder.
5925 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
5927 Use some of gnulib's new modules, taken from coreutils.
5929 * bootstrap: Sync from coreutils, except add support for gnulib_files.
5930 * bootstrap.conf: New file.
5931 (gnulib_modules): Add configmake, inttypes, unistd.
5932 (XGETTEXT_OPTIONS): Add complain, complain_at,
5933 fatal, fatal_at, warn, warn_at, unexpected_end.
5934 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
5935 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
5937 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
5939 (GNULIB_AUTOCONF_SNIPPET): Remove.
5940 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
5942 * lib/.cvsignore: Add inttypes_.h.
5943 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
5944 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
5945 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
5946 no-longer-necessary initializations.
5947 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
5948 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
5949 use the unistd module.
5950 * src/system.h: Likewise.
5951 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
5952 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
5953 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
5954 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
5955 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
5956 * src/system.h: Include inttypes.h unconditionally, now that we
5957 use the inttypes module. Don't bother to include stdint.h, since
5958 inttypes.h now does that for us.
5959 (LOCALEDIR): Remove, now that we use the configmake module.
5960 * src/getargs.c: Include configmake.h.
5961 * src/main.c: Likewise.
5962 * src/output.c: Likewise.
5963 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
5964 not from $abs_top_builddir, since config.h moved.
5967 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
5968 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
5970 * src/parse-gram.y (symbol_declaration): Don't put statements
5971 before declarations; it's not portable to C89.
5972 * src/scan-code.l (handle_action_at): Likewise.
5974 * src/scan-code.l: Always initialize braces_level; the old code
5975 left it uninitialized and therefore had undefined behavior.
5977 Don't attempt to redefine 'assert', since it runs afoul of
5978 systems where standard headers (mistakenly) include <assert.h>.
5979 Instead, define and use our own alternative, called 'aver'.
5980 * src/reader.c: Don't include assert.h, since we no longer
5982 * src/scan-code.l: Likewise.
5983 * src/system.h (assert): Remove, replacing with....
5984 (aver): New function, taking a bool arg. All uses changed.
5985 * src/tables.c (pack_vector): Ensure that aver arg is bool,
5986 not merely an integer.
5988 2006-09-15 Bob Rossi <bob@brasko.net>
5990 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
5991 * data/c.m4 (YYPUSH): New.
5992 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
5993 * src/getargs.c (push_parser): New var.
5994 * src/getargs.h (push_parser): New declaration.
5995 * src/output.c (prepare): Add macro insertion of `push_flag'.
5996 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
5997 (prologue_declaration): Parse %push-parser.
5998 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
5999 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
6000 list of removed lines from the traces observed.
6001 (AT_CHECK_CALC_LALR): Added push parser tests.
6003 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
6005 * NEWS: Version 2.3a.
6006 * configure.ac (AC_INIT): Likewise.
6008 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
6009 "#define YYSTYPE int" that caused "make maintainer-check" to fail
6010 due to header ordering dependencies. I don't know why the #define
6013 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
6014 runtime cost when YYDEBUG is not defined, and so that some tests
6015 that used to fail now work. Problem and initial suggestion by
6017 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
6018 * data/glr.cc (b4_parser_class_name):
6019 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
6020 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
6021 (yydebug_) [YYDEBUG]: New member.
6022 (yycdebug_): Now defined only if YYDEBUG.
6023 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
6024 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
6025 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
6027 (debug_stream, set_debug_stream, debug_level, set_debug_level):
6028 Define only if YYDEBUG.
6029 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
6031 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
6032 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
6033 AT_CHECK_CALC_GLR_CC that are working now.
6035 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
6037 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
6038 We don't need them in glr.cc, and glr.c defines them.
6039 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
6040 assumes that defining it to anything is the same as defining
6041 it to 1. Problem reported by Paolo Bonzini.
6043 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
6045 * data/c.m4 (b4_null, b4_case): Define.
6046 * src/output.c (prepare_symbols): Use b4_null.
6047 (user_actions_output): Use b4_case.
6049 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
6051 * data/glr.c (b4_shared_declarations): Put start-header first,
6052 before any #includes that we generate, so that feature-test
6053 macros work. Problem reported by Michael Deutschmann in
6054 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
6055 * data/lalr1.cc: Likewise.
6056 * doc/bison.texinfo (Prologue): Document that feature-test macros
6057 should be defined before any Bison declarations.
6058 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
6059 that depend on location.hh after, not before, Bison decls, since
6060 we now include location.hh after the first user prologue.
6062 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
6063 Sander Brandenburg in
6064 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
6065 Also, fix minor white space and comment issues.
6066 (Prologue): Mention that it's better to define feature-test macros
6067 before Bison declarations. Problem reported by Michael Deutschmann.
6069 * README-cvs: Fix typo: "&" should be "&&". Problem reported
6071 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
6072 This adjusts to recent gnulib changes.
6074 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6076 Finish implementation of per-type %destructor/%printer. Discussed
6078 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
6080 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
6081 * NEWS (2.3+): Add a description of this feature to the default
6082 %destructor/%printer description.
6083 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
6084 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
6085 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
6086 list node contains a semantic type.
6087 * src/symtab.c, src/symtab.h: Extend with a table that associates
6088 semantic types with their %destructor's and %printer's.
6089 (semantic_type_from_uniqstr, semantic_type_get,
6090 semantic_type_destructor_set, semantic_type_printer_set): New functions
6091 composing the public interface of that table.
6092 (symbol_destructor_get, symbol_destructor_location_get,
6093 symbol_printer_get, symbol_printer_location_get): If there's no
6094 per-symbol %destructor/%printer, look up the per-type before trying
6096 * tests/actions.at (Per-type %printer and %destructor): New test case.
6097 * tests/input.at (Default %printer and %destructor redeclared):
6098 Extend to check that multiple occurrences of %symbol-default in a
6099 single %destructor/%printer declaration is an error.
6100 (Per-type %printer and %destructor redeclared, Unused values with
6101 per-type %destructor): New test cases.
6103 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6105 Require default %destructor/%printer to be declared using
6106 %symbol-default instead of an empty symbol list, and start working on
6107 new per-type %destructor/%printer. Discussed at
6108 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
6109 * NEWS (2.3+): Add %symbol-default to example.
6110 * bison.texinfo (Freeing Discarded Symbols): Likewise.
6111 (Table of Symbols): Add entry for %symbol-default.
6112 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
6113 (generic_symlist, generic_symlist_item): New nonterminals for creating
6114 a list in which each item is a symbol, semantic type, or
6116 (grammar_declaration): Use generic_symlist in %destructor and %printer
6117 declarations instead of symbols.1 or an empty list.
6118 (symbol_declaration, precedence_declaration, symbols.1): Update actions
6119 for changes to symbol_list.
6120 * src/reader.c: Update for changes to symbol_list.
6121 * src/scan-code.l: Likewise.
6122 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
6123 * src/symlist.c, src/symlist.h: Extend such that a list node may
6124 represent a semantic type or a %symbol-default in addition to just an
6125 ordinary symbol. Add switched functions for setting %destructor's and
6127 * tests/actions.at, tests/input.at: Add %symbol-default to all default
6128 %destructor/%printer declarations.
6130 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
6132 Whether the default %destructor/%printer applies to a particular symbol
6133 isn't a question of whether the user *declares* that symbol (in %token,
6134 for example). It's a question of whether the user by any means
6135 *defines* the symbol at all (by simply using a char token, for
6136 example). $end is defined by Bison whereas any other token with token
6137 number 0 is defined by the user. The error token is always defined by
6138 Bison regardless of whether the user declares it with %token, but we
6139 may one day let the user define error as a nonterminal instead.
6140 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
6141 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
6142 the meaning of "user-defined".
6143 * tests/actions.at (Default %printer and %destructor for user-declared
6144 end token): Rename to...
6145 (Default %printer and %destructor for user-defined end token): ...
6148 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
6149 computation of whether to apply the default, don't maintain a list of
6150 every Bison-defined symbol. Instead, just check for a first character
6151 of '$', which a user symbol cannot have, and check for the error token.
6153 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
6155 Don't apply the default %destructor or %printer to the error token,
6156 $undefined, or $accept. This change fits the general rule that the
6157 default %destructor and %printer are only for user-declared symbols,
6158 and it solves several difficulties that are described in the new test
6160 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
6161 * tests/actions.at (Default %printer and %destructor are not for error
6162 or $undefined, Default %printer and %destructor are not for $accept):
6165 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
6167 Allow %start after the first rule.
6168 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
6169 when parsing the first rule.
6170 (check_and_convert_grammar): Search for it here after all grammar
6171 declarations have been parsed. Skip midrules, which have dummy LHS
6173 * src/symtab.c (symbol_is_dummy): New function.
6174 * src/symtab.h (symbol_is_dummy): Declare it.
6175 * tests/input.at (%start after first rule): New test.
6177 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6179 Redo some of the previous commit: add back the ability to use
6180 non-aliased/undeclared string literals since it might be useful to
6181 those declaring %token-table.
6182 * src/reader.c (check_and_convert_grammar): Undo changes in previous
6183 commit: don't worry about complaints from symbols_pack.
6184 * src/symtab.c (symbol_new, symbol_class_set,
6185 symbol_check_alias_consistency): Undo changes in previous commit: count
6186 each string literal as a new symbol and token, assign it a symbol
6187 number, and don't complain about non-aliased string literals.
6188 (symbols_pack): Since symbol_make_alias still does not decrement symbol
6189 and token counts but does still set aliased tokens to the same number,
6190 symbol_pack_processor now leaves empty slots in the symbols array.
6192 * tests/regression.at (Undeclared string literal): Remove test case
6193 added in previous commit since non-aliased string literals are allowed
6195 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
6196 remove unnecessary string literal declarations.
6197 * tests/sets.at (Firsts): Likewise.
6199 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6201 Don't allow an undeclared string literal, but allow a string literal to
6202 be used before its declaration.
6203 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
6204 symbols_pack complained.
6205 * src/symtab.c (symbol_new): Don't count a string literal as a new
6207 (symbol_class_set): Don't count a string literal as a new token, and
6208 don't assign it a symbol number since symbol_make_alias does that.
6209 (symbol_make_alias): It's not necessary to decrement the symbol and
6210 token counts anymore. Don't assume that an alias declaration occurs
6211 before any uses of the identifier or string, and thus don't assert that
6212 one of them has the highest symbol number so far.
6213 (symbol_check_alias_consistency): Complain if there's a string literal
6214 that wasn't declared as an alias.
6215 (symbols_pack): Bail if symbol_check_alias_consistency failed since
6216 symbol_pack asserts that every token has been assigned a symbol number
6217 although undeclared string literals have not.
6218 * tests/regression.at (String alias declared after use, Undeclared
6219 string literal): New test cases.
6220 (Characters Escapes, Web2c Actions): Declare string literals as
6222 * tests/sets.at (Firsts): Likewise.
6224 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
6226 In the grammar scanner, STRING_FINISH unclosed constructs and return
6227 them to the parser in order to improve error messages.
6228 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
6229 SC_BRACED_CODE, SC_PROLOGUE): Implement.
6230 * tests/input.at (Unclosed constructs): New test case.
6231 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
6234 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
6237 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
6239 Handle string aliases for character tokens correctly.
6240 * src/symtab.c (symbol_user_token_number_set): If the token has an
6241 alias, check and set its alias's user token number instead of its own,
6242 which is set to indicate the alias. Previously, every occurrence of
6243 the character token in the grammar overwrote that alias indicator with
6245 * tests/input.at (String aliases for character tokens): New test.
6247 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
6249 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
6251 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
6253 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
6254 to prevent failures when building on older platforms.
6255 Check for autopoint failure.
6256 Set XGETTEXT_OPTIONS to values that check for C format strings,
6257 so that translators are warned about them (this also helps
6258 prevent core dumps).
6260 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
6261 function, since it simplifies our code a bit.
6263 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
6264 rather than -W, so we don't get bogus warnings about sign comparisons.
6265 Add -Wpointer-arith, since that warning is useful (it reports code
6266 that does not conform to C89 and that some compilers reject).
6267 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
6268 since it's no longer needed.
6270 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
6272 Clean up scanners a bit.
6273 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
6274 definitions so gcc won't warn when obstack_for_string is unused.
6275 * src/scan-code.l: config.h and system.h are already #include'd by
6276 scan-code-c.c, so get rid of them here.
6277 * src/scan-gram.l: Likewise.
6278 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
6279 definitions rather than duplicating the rest of it.
6280 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
6282 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
6284 Suppress signed/unsigned comparison warnings for yycheck.
6285 * data/c.m4 (b4_safest_int_type): New macro.
6286 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
6287 a signed int type, cast it to b4_safest_int_type first.
6288 * data/yacc.c: Likewise.
6289 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
6292 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
6294 * doc/bison.texinfo: Fix some typos.
6296 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
6298 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
6299 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
6301 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
6302 the latest gnulib does this a different way.
6303 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
6304 translation was patched, so stop omitting it.
6306 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6308 Enable declaration of default %printer/%destructor. Make the parser
6309 use these for all user-declared grammar symbols for which the user does
6310 not declare a specific %printer/%destructor. Thus, the parser uses it
6311 for token 0 if the user declares it but not if Bison generates it as
6312 $end. Discussed starting at
6313 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
6314 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
6316 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
6317 * NEWS (2.3+): Mention.
6318 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
6319 declare a %destructor for a mid-rule's semantic value. It's just
6320 impossible to declare one specific to it.
6321 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
6322 code. Describe default %destructor form.
6323 * src/parse-gram.y (grammar_declaration): Parse default
6324 %printer/%destructor declarations.
6325 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
6326 and symbol_destructor_location_get rather than accessing the destructor
6327 and destructor_location members of struct symbol.
6328 (symbol_printers_output): Likewise but for %printer's.
6329 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
6331 * src/symtab.c (default_destructor, default_destructor_location,
6332 default_printer, default_printer_location): New static global
6333 variables to record the default %destructor and %printer.
6334 (symbol_destructor_get, symbol_destructor_location_get,
6335 symbol_printer_get, symbol_printer_location_get): New functions to
6336 compute the appropriate %destructor and %printer for a symbol.
6337 (default_destructor_set, default_printer_set): New functions to set the
6338 default %destructor and %printer.
6339 * src/symtab.h: Prototype all those new functions.
6340 * tests/actions.at (Default %printer and %destructor): New test to
6341 check that the right %printer and %destructor are called, that they're
6342 not called for $end, and that $$ and @$ work correctly.
6343 (Default %printer and %destructor for user-declared end token): New
6344 test to check that the default %printer and %destructor are called for
6345 a user-declared end token.
6346 * tests/input.at (Default %printer and %destructor redeclared, Unused
6347 values with default %destructor): New tests to check related grammar
6348 warnings and errors.
6350 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6352 Clean up handling of %destructor for the end token (token 0).
6353 Discussed starting at
6354 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
6356 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
6358 Make the skeletons consistent in how they pop the end token and invoke
6360 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
6361 state, which has token number 0, since this would invoke the
6362 %destructor for the end token.
6363 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
6364 until after shifting the end token, or else it won't be popped.
6365 * data/yacc.c (yyparse): Likewise.
6367 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
6368 it's the end token. Upon termination, destroy an unshifted lookahead
6369 even when it's the end token.
6370 * data/lalr1.cc (yy::parser::parse): Likewise.
6371 * data/yacc.c (yyparse): Likewise.
6373 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
6374 value warnings for the end token when the user gives the end token a
6377 * tests/actions.at (Printers and Destructors): Test all the above.
6379 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
6381 Update to latest gnulib and gettext versions.
6382 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
6384 (gnulib_files): Add m4/warning.m4. Don't worry about files
6385 overwritten by autopoint.
6386 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
6387 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
6389 Don't use autoreconf; instead, invoke autopoint etc. by hand,
6390 so that we can remove the intl files at a better time.
6391 (intl_files_to_remove): Remove aclocal.m4, since it gets
6392 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
6393 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
6394 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
6395 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
6396 Remove datarootdir hack; no longer needed.
6397 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
6398 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
6399 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
6401 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
6402 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
6404 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
6406 * bootstrap: Adjust to today's change to gnulib-tool by invoking
6407 it with --assume-autoconf='latest-stable'.
6409 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
6411 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
6412 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
6414 * src/muscle_tab.h (muscle_grow): Replace the header comments with
6415 those from muscle_tab.c since the old ones are misleading.
6417 2006-07-13 Akim Demaille <akim@epita.fr>
6419 Support %define "KEY" {VALUE}.
6420 * src/scan-code.h, src/scan-code.l (translate_action)
6421 (translate_rule_action, translate_symbol_action, translate_code):
6422 Return char *, not const char *.
6423 * src/parse-gram.y (declaration): Rename as...
6424 (prologue_declaration): this.
6425 (string_content): Remove this nonterminal, use STRING.
6426 (braceless, content, content.opt): New nonterminal.
6428 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
6430 * src/scan-gram.l (getargs.h): Don't include it.
6432 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
6434 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
6435 rather than a for-loop that declares a local bool variable. This
6436 should work around a compatibility problem with a Cray x1e C++
6437 compiler reported by Hung Nguyen in
6438 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
6439 The for-loop was introduced in the 2004-11-17 change but I don't
6440 know why it was needed.
6442 2006-07-12 Akim Demaille <akim@epita.fr>
6444 * data/c.m4: Comment changes.
6446 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
6448 * src/complain.c (error_message, ERROR_MESSAGE): New.
6450 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
6451 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
6453 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
6455 * NEWS: Instead of %union, you can define and use your own union type
6456 YYSTYPE if your grammar contains at least one <type> tag.
6457 Your YYSTYPE need not be a macro; it can be a typedef.
6458 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
6459 (Union Decl, Decl Summary): Document this.
6460 * data/glr.c (YYSTYPE): Implement this.
6461 * data/glr.cc (YYSTYPE): Likewise.
6462 * data/lalr1.cc (YYSTYPE): Likewise.
6463 * data/yacc.c (YYSTYPE): Likewise.
6464 * src/output.c (prepare): Output tag_seen_flag.
6465 * src/parse-gram.y (declaration, grammar_declaration):
6466 Use 'union_seen' rather than 'typed' to determine whether
6467 %union has been seen, since grammars can now be typed without
6469 (symbol_declaration, type.opt, symbol_def):
6470 Keep track of whether a tag has been seen.
6471 * src/reader.c (union_seen, tag_seen): New vars.
6473 * src/reader.h (union_seen, tag_seen, typed): Likewise.
6474 * src/scan-code.l (untyped_var_seen): New variable.
6475 (handle_action_dollar): Adjust to above changes.
6476 (handle_action_dollar, handle_action_at):
6477 Improve overflow checking for outlandish numbers.
6478 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
6479 avoid new diagnostics generated by above changes.
6480 * tests/regression.at (YYSTYPE typedef): Add test to check
6481 for type tags without %union.
6483 * src/symlist.c (symbol_list_length): Return int, not unsigned
6484 int, since callers expect int. This may need to get revisited
6485 once we have proper integer overflow checking.
6487 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
6488 object is now static.
6490 * src/getargs.c (flags_argmatch): Return void, not int,
6491 to pacify ./configure --enable-gcc-warnings.
6493 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
6494 since last_string is already defined to FLEX_PREFIX (last_string).
6496 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
6498 Implement --warnings/-W.
6499 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
6501 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
6503 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
6504 (warnings_args, warnings_types): New.
6505 (getargs, short_options, long_options): Accept -W/--warnings.
6506 Sort the options by alphabetical order, upper case letter right
6507 before its lower case.
6509 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
6511 Change %merge result type clash warnings to errors. Discussed at
6512 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
6513 * src/reader.c (record_merge_function_type): Use complain_at.
6514 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6515 declared later): Update test case results.
6517 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
6519 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
6520 to be in alphabetical order.
6521 (trace_args): Spelling fixes.
6523 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
6525 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
6526 so they don't collide with user-defined macros.
6527 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
6528 this was never guaranteed, and now that we're using gnulib stdint,
6529 which defines int_fast16_t to long int, the problem is exposed.
6531 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
6533 * data/c.m4 (b4_basename): Simplify a bit, since we don't
6534 need the full POSIX semantics (and weren't implementing them
6537 Adjust to Autoconf 2.60 and today's gnulib.
6538 * bootstrap (gnulib_modules): Add stdint.
6539 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
6540 no longer copies it.
6541 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
6542 since stdint needs the former and wcwidth (which is now required
6543 by mbswidth) needs the latter.
6544 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
6545 work around a compatibility glitch between gettext 0.14.6 and
6547 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
6548 Do not check for uintptr_t, since new stdint module does the right
6550 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
6551 Add stdint.h, stdint_.h, wcwidth.h.
6552 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
6553 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
6554 stdint.m4, wchar_t.m4, wcwidth.m4.
6555 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
6556 usual order for ../lib/*.h files.
6557 (file_name_split): Use last_component, not base_name, to adjust
6559 * src/parse-gram.h: Include <strverscmp.h> in the usual order
6560 for ../lib/*.h files.
6561 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
6562 Define unconditionally, since we now assume the stdint module.
6563 * src/scan-skel.l: Include <dirname.h>.
6564 (BASE_QPUTS): Use last_component, not base_name.
6565 * src/system.h: Include <unlocked-io.h> in the usual order
6566 for ../lib/*.h files. Include <stdint.h> unconditionally,
6567 since we now use the stdint module.
6568 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
6569 HAVE_UINTPTR_T, since we now use the stdint module.
6570 (base_name): Remove decl, since files now include <dirname.h>
6573 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
6575 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
6577 * data/yacc.c, data/glr.c, data/location.cc: Use them.
6578 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
6580 * tests/calc.at: Adjust.
6582 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
6584 * data/c.m4 (b4_basename): New.
6585 (b4_syncline): Also output the location of its invocation (from
6587 (b4_user_action, b4_define_user_action, b4_user_actions)
6588 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
6589 (b4_user_stype): New.
6590 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
6592 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6594 In the grammar file, the first column is 1 not 0 on the first line as
6595 on every other line.
6596 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
6597 * tests/input.at (Torturing the Scanner): Update output.
6599 * src/scan-gram.l (scanner_cursor): Declare it static.
6601 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6603 In warnings, say "previous declaration" rather than "first
6605 * src/symtab.c (redeclaration): Do that here.
6606 * src/reader.c (record_merge_function_type): In the case of a result
6607 type clash, report the previous declaration rather than the very first
6608 one in the grammar file.
6609 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6610 declared later): Add a third declaration to check this behavior.
6611 * tests/input.at (Incompatible Aliases): Update output.
6613 2006-06-27 Akim Demaille <akim@epita.fr>
6615 * doc/Doxyfile.in: New.
6616 * doc/Makefile.am: Use it.
6617 * src/lalr.h, src/symtab.h: Initial doxygenation.
6619 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6621 Don't miss %merge result type warnings just because the LHS types are
6622 declared after the %merge. This continues the effort of the previous
6624 * src/reader.c (get_merge_function): Don't set the merger type yet.
6625 (record_merge_function_type): New function for setting the merger type
6626 and checking for clashes.
6627 (grammar_current_rule_merge_set): Set the location of the %merge for
6629 (packgram): Invoke record_merge_function_type for each rule now that
6630 all symbol type declarations have been parsed.
6631 * src/reader.h (merger_list.type_declaration_location): New member
6632 storing the location of the first %merge from which the type for this
6633 merging function was derived.
6634 * src/symlist.h (symbol_list.merger_declaration_location): New member
6635 storing the location of a rule's %merge, if any.
6636 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6637 declared later): New test to catch the error fixed by the above patch.
6639 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6641 Get action warnings (grammar_rule_check) right even when symbol
6642 declarations appear after the rules. Discussed at
6643 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
6645 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
6646 Don't mistake the type of $$ in a midrule to be that of its parent
6648 * src/reader.c (grammar_current_rule_end): Don't invoke
6649 grammar_rule_check yet since not all symbol declarations may have been
6651 (grammar_midrule_action): Likewise.
6652 Don't record whether the midrule's $$ has been used yet since actions
6653 haven't been translated yet.
6654 Record the midrule's parent rule and its RHS index within the parent
6656 (grammar_current_rule_action_append): Don't translate the action yet
6657 since not all symbol declarations may have been parsed yet and, thus,
6658 warnings about types for $$, $n, @$, and @n can't be reported yet.
6659 (packgram): Translate the action and invoke grammar_rule_check now that
6660 all symbol declarations have been parsed.
6661 * src/scan-code.l (handle_action_dollar): Now that this is invoked
6662 after parsing the entire grammar file, the symbol list here in the case
6663 of a midrule is actually the midrule's empty RHS, so reference its
6664 parent rule's RHS where necessary.
6665 On the other hand, now that you can already know it's a midrule, you
6666 aren't forced to think $$ has the same type as its parent rule's $$.
6667 (handle_action_at): In the case of a midrule, reference the parent rule
6669 * src/symlist.c (symbol_list_new): Initialize new midrule-related
6671 (symbol_list_length): Now that this is invoked after all rules have
6672 been parsed, a NULL symbol (rather than a NULL symbol list node)
6673 terminates a rule. symbol_list_print already does this correctly.
6674 * src/symlist.h (symbol_list.midrule_parent_rule,
6675 symbol_list.midrule_parent_rhs_index): New members so that midrules can
6676 remember their relationships with their parents.
6677 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
6678 fixed by the above patch.
6679 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
6681 (Unused values): ... this old test case and...
6682 (Unused values before symbol declarations): ... this new test case.
6683 This one is the same as `Unused values' except that all symbol
6684 declarations appear after the rules in order to catch the rest of the
6685 errors fixed by the above patch.
6687 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6690 * src/reader.c (current_rule): Declare it static since it's no longer
6691 used outside this file.
6692 (grammar_current_rule_action_append): Remove redundant arguments from
6693 translate_rule_action invocation.
6694 * src/reader.h (current_rule): Remove this unused extern.
6695 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
6696 * src/scan-code.l (translate_rule_action): Likewise.
6698 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
6700 Clean up yesterday's patch.
6701 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
6703 * src/reader.c (grammar_current_rule_action_append): ... here for
6704 consistency with grammar_current_rule_symbol_append.
6705 * tests/regression.at (Braced code in declaration in rules section):
6706 Make yyerror and yylex static as usual.
6708 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
6710 Fix bug that mistakes braced code in a declaration in the rules section
6711 to be a rule action. Mentioned at
6712 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
6713 * src/scan-gram.l: Move midrule action detection from the start of the
6714 scanning of any braced code to...
6715 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
6716 action. For readability, use $2 and @2 rather than the equivalent
6718 * tests/regression.at (Braced code in declaration in rules section):
6719 New test to catch the error fixed by the above patch.
6721 Work on code readability some.
6722 * src/scan-code.l (current_rule): Get rid of this misleading and
6723 redundant declaration: it's actually extern'ed in reader.h.
6724 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
6725 translate_action): Add a rule argument and use it instead of the global
6727 (translate_rule_action): This already receives current_rule through an
6728 argument, so pass it on to translate_action instead of assigning
6729 current_rule to current_rule.
6730 (translate_symbol_action, translate_code): Pass rule = NULL to
6733 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
6735 Rename %before-definitions to %start-header and %after-definitions to
6736 %end-header. Don't use these declarations to separate pre-prologue
6737 blocks from post-prologue blocks. Add new order-independent
6738 declarations %before-header and %after-header as alternatives to the
6739 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
6740 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
6741 * NEWS (2.3+): Update for these changes.
6742 * data/glr.c (b4_before_definitions): Update to...
6743 (b4_start_header): ... this.
6744 (b4_after_definitions): Update to...
6745 (b4_end_header): ... this.

6749 * doc/bison.texinfo (The prologue): Update names, and replace remaining
6750 prologue blocks with %*-header declarations.
6751 (Calc++ Parser): Likewise.
6752 (Decl Summary): Update names.
6753 (Table of Symbols): Update description.
6754 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
6755 (PERCENT_END_HEADER): ... this.
6756 (PERCENT_BEFORE_DEFINITIONS): Update to...
6757 (PERCENT_START_HEADER): ... this.
6758 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6759 (declaration): Update token names and m4 macro names.
6760 When parsing %end-header and %start-header, invoke translate_code
6761 before muscle_code_grow, and no longer set global booleans to remember
6762 whether these declarations have been seen.
6763 Parse new %after-header and %before-header.
6764 * src/reader.c (before_definitions, after_definitions): Remove.
6765 (prologue_augment): Accept a new bool argument to specify whether to
6766 augment the pre-prologue or post-prologue.
6767 * src/reader.h (before_definitions, after_definitions): Remove these
6769 (prologue_augment): Add new bool argument.
6770 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
6771 (PERCENT_END_HEADER): ... this.
6772 (PERCENT_BEFORE_DEFINITIONS): Update to...
6773 (PERCENT_START_HEADER): ... this.
6774 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6775 * tests/actions.at (Printers and Destructors): Update names.
6777 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
6779 Add comparison operators for C++ location classes. Discussed at
6780 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
6781 * data/c++.m4 (b4_define_location_comparison): New boolean %define
6782 declaration indicating whether filename_type has an operator==. If
6783 filename_type is `std::string', it defaults to `1', `0' otherwise.
6784 * data/location.cc: Iff b4_define_location_comparison is `1', add
6785 operator== and operator!= for class position and for class location.
6788 * src/scan-action.l: Remove unused file.
6789 * src/symtab.c (symbol_printer_set): Use printer_location not

6796 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
6798 Don't put the pre-prologue in the header file. For the yacc.c code
6799 file and the glr.c header and code files, move the pre-prologue before
6800 the token definitions. Add new %before-definitions and
6801 %after-definitions to declare code that will go in both the header file
6802 and code file. Discussed at
6803 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
6804 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
6806 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
6807 * NEWS (2.3+): Describe these changes.
6808 * data/glr.c (b4_pre_prologue): Move from within to before...

6810 Add new b4_before_definitions before b4_token_enums.
6811 Add new b4_after_definitions at the end.
6812 * data/glr.cc (b4_pre_prologue): Replace with...
6813 (b4_before_definitions): ... this in the header file.
6814 (b4_after_definitions): New near the end of the header file.
6815 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
6816 code file right before including the header file.
6817 (b4_before_definitions): New in the previous position of
6818 b4_pre_prologue in the header file.
6819 (b4_after_definitions): New near the end of the header file.
6820 * data/yacc.c: Clean up some m4 quoting especially in the header file.
6821 (b4_token_enums_defines): In the code file, move to right before
6822 YYSTYPE for consistency with the header file.
6823 (b4_before_definitions): New right before b4_token_enums_defines in
6824 both the header and code file.
6825 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
6826 header and code file.
6827 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
6828 of prologues for %union dependencies.
6829 (Decl Summary): In %defines description, mention the effect of
6830 %before-definitions and %after-definitions on the header file.
6831 (Calc++ Parser): Forward declare driver in a %before-definitions rather
6832 than in the pre-prologue so that make check succeeds.
6833 (Table of Symbols): Add entries for %before-definitions and
6835 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
6836 %before-definitions.
6837 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
6838 (declaration): Parse those declarations and append to
6839 b4_before_definitions and b4_after_definitions, respectively.
6840 * src/reader.c (before_definitions, after_definitions): New bools to
6841 track whether those declarations have been seen.
6842 (prologue_augment): Add to the post-prologue if %union,
6843 %before-definitions, or %after-definitions has been seen.
6844 * src/reader.h (before_definitions, after_definitions): New extern's.
6845 * src/scan-gram.l: Scan the new declarations.
6846 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
6847 prologue block in a %before-definitions or a %after-definitions based
6848 on whether the %union is declared.
6849 * tests/regression.at (Early token definitions with --yacc, Early token
6850 definitions without --yacc): Move tests for token definitions into the
6851 post-prologue since token names are no longer defined in the
6854 2006-06-20 Akim Demaille <akim@epita.fr>
6856 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
6857 (symbol_get): Use it.
6858 * src/parse-gram.y: Use it.
6860 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
6862 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
6863 build succeeds when configured with --enable-gcc-warnings.
6865 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
6867 * src/parse-gram.y (char_name): New function.
6868 (CHAR, STRING, string_content): For %printer, properly escape.
6869 (ID): Prefer fputs to fprintf.
6870 (id): Reindent to be consistent with other rules.
6871 Properly quote char.
6873 The Translation Project changed its way of publishing translations
6874 to maintainers. I haven't received any responses to my request
6875 for supporting the old way, or for documenting the new way. I
6876 have modified 'bootstrap' to use screen scraping
6877 (in this case, HTML scraping). This is unreliable and inelegant,
6878 but I don't see any better way. Yuck.
6879 * bootstrap (TP_URL, WGET_COMMAND): New vars.
6880 (get_translations): New function, which uses HTML scraping to
6881 deduce locations of latest translations.
6882 Use this function to grab both bison and bison-runtime .po files.
6883 Don't bother priming the pump for the runtime-po domain any more,
6884 as it's now translated better than bison is.
6886 2006-06-19 Akim Demaille <akim@epita.fr>
6888 * src/scan-gram.l: No longer "parse" things after `%union' until
6889 `{'. Rather, return a single "%union" token.
6890 No longer make symbols: return strings, and leave the conversion
6891 to symbols to the parser.
6892 (SC_PRE_CODE, token_type): Remove.
6893 * src/parse-gram.y (%union): New field `character'.
6896 (ID, ID_COLON): Now that the scanner no longer makes them
6897 identifiers, adjust all uses to invoke symbol_get.
6898 (id_colon): New, wraps the conversion from string to symbol.
6899 (%union): Accept a possible union_name.
6900 (symbol): Now can be a char.
6901 * data/c.m4 (b4_union_name): Leave a default value.
6902 * data/glr.c, data/yacc.c: Use it.
6904 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
6906 For associating token numbers with token names for "yacc.c", don't use
6907 #define statements unless `--yacc' is specified; always use enum
6908 yytokentype. Most important discussions start at:
6909 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
6910 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
6912 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
6913 * NEWS (2.3+): Mention.
6914 * data/c.m4 (b4_yacc_if): New.
6915 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
6917 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
6918 on token name definitions.
6919 * src/getargs.c (usage): Capitalize `Yacc' in English.
6920 * src/output.c (prepare): Define b4_yacc_flag.
6921 * tests/regression.at (Early token definitions): Test that tokens names
6922 are defined before the pre-prologue not just before the post-prologue.
6923 Remove this test case and copy to...
6924 (Early token definitions with --yacc): ... this to test #define's.
6925 (Early token definitions without --yacc): ... and this to test enums.
6927 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
6929 * NEWS: Reword the post-2.3 change to not be so optimistic about
6930 removing the old "look-ahead" spelling.
6931 Update previous look-ahead/lookahead change reports.
6932 * REFERENCES: look-ahead -> lookahead (since that's
6933 what he actually wrote).
6934 * doc/refcard.tex: look ahead -> lookahead,
6935 look-ahead -> lookahead
6937 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
6939 For consistency, use `lookahead' instead of `look-ahead' or
6940 `look_ahead'. Discussed starting at
6941 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>

7017 Bison without installing the yacc script.
7019 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
7021 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
7022 and yytext if they're already #define'd.

7052 2006-06-06 Akim Demaille <akim@epita.fr>
7054 Extract the parsing of user actions from the grammar scanner.
7055 As a consequence, the relation between the grammar scanner and

7121 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7123 Between Bison releases, manually append `+' to the previous Bison
7124 release number, and use that as a signal to automatically print the
7125 ChangeLog's CVS Id keyword from --version. Discussed starting at
7126 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
7127 * ChangeLog: Add Id header.
7128 * configure.ac (AC_INIT): Append `+' to `2.3'.

7130 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
7131 (BUILT_SOURCES): Add revision.c.
7132 (revision.c): New target rule. This file defines a new global variable
7133 named revision. It initializes it with either the Id from ChangeLog
7134 or, if VERSION doesn't contain `+', with the empty string.
7135 * src/getargs.c (version): Print the value of revision.
7136 * src/revision.h: Extern revision.
7138 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7140 * NEWS: Version 2.3.

7143 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7145 * data/glr.c (YYRECOVERING): Define to be a function-like macro
7146 with no arguments, not as an object-like macro. This is for
7147 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
7148 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
7149 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
7152 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
7154 * src/getargs.c (usage): Back out yesterday's modification of the
7155 --help output so that we don't have to wait for translation before
7158 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
7160 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
7161 Problem reported by Akim Demaille.
7163 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
7165 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
7167 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
7169 * data/yacc.c (yy_reduce_print): Omit trailing white space in
7170 generated source code. Problem reported by Frans Englich in
7171 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
7173 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
7175 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
7176 shell, not within 'make', so that 'make' by an ordinary builder
7177 (using GNU make) does not worry about configuring gzip. This also
7178 works around a bug reported independently by Keith Thompson and by
7179 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
7180 stderr rather than stdout, messing up the build logs.
7182 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7184 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
7185 to make sure that YYID will never be unused. This fixes a 'make
7186 maintainer-check' failure caused by the recent changes to the 'Trivial
7187 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
7189 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
7191 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7193 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
7194 state before an empty RHS is always resolved here. Only the location
7195 of that state is guaranteed to be resolved, and that's enough. This
7196 fixes the remaining bug reported by Derek M. Jones in
7197 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7198 * tests/glr-regression.at (Uninitialized location when reporting
7199 ambiguity): Test the above case.
7200 Also, the embedded comments in this test case claim it checks the case
7201 of an empty RHS that has inherited the initial location. However, the
7202 corresponding LHS was already resolved, so yyresolveLocations didn't
7203 actually have reason to modify it. Fix this by forcing
7204 nondeterministic operation at the beginning of the parse.
7206 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
7208 * data/c.m4 (b4_yy_symbol_print_generate):
7209 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
7210 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
7211 of the bugs reported today by Derek M Jones in
7212 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7213 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
7214 defined to be a type name without parens or brackets.
7215 (Location Type): Similarly for YYLTYPE.
7216 * tests/regression.at (Trivial grammars): Put in a test for this
7217 bug that will be caught by 'make maintainer-check' (though not,
7218 alas, by 'make check' unless your compiler is picky).
7220 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>

7225 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
7227 * data/glr.c (yyreportTree): Make room in yystates for the state
7228 preceding the RHS. This fixes the segmentation fault reported by Derek
7230 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
7231 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
7232 to the user. Reported for yyreportTree by Derek M. Jones later in the
7234 * THANKS: Add Derek M. Jones.
7235 Update my email address.
7236 Fix typo in Steve Murphy's name.
7238 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
7240 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
7241 checking against YYLAST that caused the parser to miss a potential
7242 alternative in its diagnostic.
7243 Problem reported by Maria Jose Moron Fernandez in
7244 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.

7246 * data/yacc.c (yysyntax_error): Likewise.
7247 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
7248 tokens, in case we run into an older C compiler.
7249 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
7250 Use them to check for the off-by-one error fixed above.
7252 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
7253 YYSIZE_T, not size_t.
7254 * tests/regression.at (Trivial grammars): New test, to catch
7255 the error fixed by the above patch.
7257 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7259 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
7261 Reported by Steve Murphy.
7263 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7265 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
7266 * data/glr.cc: b4_location_flag is now b4_locations_flag.
7268 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7270 Implement --trace=m4.
7271 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
7272 * src/output.c (output_skeleton): When set, pass -dV to m4.
7274 Factor the handling of flags in m4.
7275 * src/output.c (prepare): Rename the muscle names debug, defines,
7276 error_verbose to debug_flag, defines_flag, error_verbose_flag.
7277 * data/c.m4: Adjust.
7278 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
7279 Use b4_define_flag_if to define other b4_FLAG_if macros.
7280 (b4_location_if): As a consequence, rename as...
7281 (b4_locations_if): this, for consistency.
7282 Adjust all the skeletons.
7284 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7286 * etc/bench.pm: Shorten bench names.
7288 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7290 * src/output.h, src/output.c (error_verbose): Move to...
7291 * src/getargs.h, src/getargs.c: here.
7293 Adjust dependencies.
7295 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
7297 * data/c.m4 (b4_copyright): Put the special exception for Bison
7298 skeletons here, so we don't have to put it in each skeleton. All
7299 uses changed. Suggested by Akim Demaille. Also, wrap the
7300 copyright notice, in case it is longer than 80 columns. Replace
7301 comma by newline after title.
7303 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
7305 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
7306 incompatibility, not a bug. Mention that it wasn't fixed as of

7311 * examples/extexi: Enforce the precedence of concatenation over

7315 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7317 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
7318 with the member "token".
7319 Reported by Martin Nylin.
7321 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
7323 * data/glr.c: Switch to Bison 2.2 special-exception language in
7324 the copyright notice. Use more-regular format for titles and

7334 * data/glr.cc: Remove dead code.
7336 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
7338 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
7339 that variable and the line breaks the bootstrap. Problem reported
7340 by Juan M. Guerrero.
7342 2006-04-24 Akim Demaille <akim@lrde.epita.fr>

7357 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
7359 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
7360 Problem reported by Bob Rossi.
7362 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
7364 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
7365 and didn't really work.
7366 For the index, use @ifnotinfo, not @iftex.
7367 Minor cleanups of spacing and terminology.
7369 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
7371 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
7372 of AT_NAME_PREFIX when %name-prefix is not used.
7374 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
7376 Apply --prefix to C++ skeletons too: they change the namespace.
7377 The test suite already exercize these cases.
7378 * data/c++.m4 (b4_namespace): New.
7379 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
7380 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
7381 * data/yacc.c, data/glr.c: Remove a useless `[]'.
7382 * doc/bison.texinfo: Document it.
7383 (Option Cross Key): Use @multitable in all formats. It looks
7384 nicer, even in TeX outputs.
7385 (Rules): Use the same code whatever the output type is.
7386 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
7387 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
7388 * tests/calc.at: Use it, instead of hard coding `yy'.

7409 Fix two nits reported by twlevo, plus one more that I discovered.
7411 * src/assoc.h (assoc_to_string): Give a name to the arg, as
7412 this is the usual Bison style.

7415 * src/reader.h (token_name): Likewise.
7417 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
7419 Fix some nits reported by twlevo.
7420 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
7421 and "POSIX". Use more-modern syntax for URLs. Mention C++
7422 and ask for Java. Don't hardwire OS version numbers. Add
7424 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
7425 * src/conflicts.c (solved_conflicts_obstack): Now static.
7427 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
7429 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
7430 page. Say "you can use it" not "you may use it" as on the web page;
7431 we're describing capabilities not granting permission.
7433 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
7435 * data/glr.c (yyresolveLocations): Rename local variables to avoid
7436 shadowing warnings. Use usual patter for iterating through RHS.
7437 * tests/glr-regression.at
7438 (Uninitialized location when reporting ambiguity):
7439 Modify yylex so that it uses its argument, rather than trying
7440 to rely on ARGSUSED (which doesn't work for gcc with warnings).
7441 const char -> char const.
7443 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
7444 Don't use tabs inside commands; it messes up 'ps'.
7445 Problem reported by twlevo.
7447 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
7449 * tests/glr-regression.at (Uninitialized location when reporting
7450 ambiguity): New test case.
7451 * data/glr.c (yyresolveLocations): New function, which uses
7453 (yyresolveValue): Invoke yyresolveLocations before reporting an
7455 * doc/bison.texinfo (Default Action for Locations): Note
7456 YYLLOC_DEFAULT's usage for ambiguity locations.
7457 (GLR Semantic Actions): Cross-reference those notes.
7459 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
7461 * tests/glr-regression.at (Leaked semantic values when reporting
7462 ambiguity): Remove unnecessary union and type declarations.
7463 (Leaked lookahead after nondeterministic parse syntax error): New test
7465 * data/glr.c (yyparse): Check for zero stacks remaining before
7466 attempting to shift the lookahead so that you don't lose it.
7468 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
7470 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
7471 * tests/glr-regression.at (Leaked semantic values when reporting
7472 ambiguity): New test case.
7473 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
7474 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
7475 now unnecessary yystackp parameter.
7476 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
7477 destructors can be called.
7479 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
7480 in existing testcases.
7482 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
7484 Don't leak semantic values for parent RHS when a user action cuts the
7485 parser, and clean up related code a bit.
7486 * tests/glr-regression.at (Leaked merged semantic value if user action
7487 cuts parse): Rename to...
7488 (Leaked semantic values if user action cuts parse): ... this. Add check
7489 for leaked parent RHS values.
7490 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
7491 between an unresolved state (non-empty chain of semantic options) and
7492 an incomplete one (signaled by an empty chain).
7493 (yyresolveStates): Document the interface. Move all manipulation of a
7494 successfully or unsuccessfully resolved yyGLRState to...
7495 (yyresolveValue): ... here so that yyresolveValue always leaves a
7496 yyGLRState with consistent data and thus is easier to understand.
7497 Remove the yyvalp and yylocp parameters since they are always just
7498 taken from the yys parameter. When reporting a discarded merged value
7499 in debugging output, note that it is incompletely merged. Document the
7501 (yyresolveAction): If resolving any of the RHS states fails, destroy
7502 them all rather than leaking them. Thus, as long as user actions are
7503 written to clean up the RHS correctly, yyresolveAction always cleans up
7504 the RHS of a semantic option. Document the interface.

7514 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
7515 mid-rule action inside a nonterminal symbol in order to declare a

7572 example if we're just doing a plain 'make'. This avoids bothering
7573 the installer unnecessarily about problems due to weird C++

7582 not portable, according to Posix and the C standard, and it does
7583 not work with Sun C 5.7, where previous #line directives affect

7623 During deterministic GLR operation, user actions should be able to
7624 influence the parse by changing yychar. To make this easier to fix and
7625 to make glr.c easier to evolve in general, don't maintain yytoken in
7626 parallel with yychar; just compute yytoken when needed.
7627 * tests/glr-regression.at (Incorrect lookahead during deterministic
7628 GLR): Check that setting yychar in a user action has the intended
7630 * data/glr.c (yyGLRStack): Remove yytokenp member.
7631 (yyclearin): Don't set *yytokenp.
7632 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
7633 yychar rather than *yytokenp to determine the current lookahead.

7653 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
7654 got from <http://bro-ids.org/download.html>. The bug is that
7655 when two actions appeared in succession, the second one was
7656 scanned before the first one was added to the grammar rule
7657 as a midrule action. Bison then output the incorrect warning
7658 "parse.y:905.17-906.36: warning: unused value: $3".

7920 in the yychar entry.
7921 In the yychar entry, remove mention of the local yychar case (pure
7922 parser) since this is irrelevant information when writing semantic
7923 actions and since it's already discussed in `Table of Symbols' where
7924 yychar is otherwise described as an external variable.
7925 In the yychar entry, don't call it the `current' look-ahead since it
7926 isn't when semantic actions are deferred.

7929 Add yylloc and yylval entries discussing look-ahead usage.
7930 (Look-Ahead Tokens): When discussing yychar, don't call it the

7956 from which the RHS is taken. Set the lookahead members of the new
7957 yySemanticOption according to the lookahead status for stack yyk.

7959 yyaddDeferredAction.
7960 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

7985 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
7987 * data/glr.c (yyresolveValue): When merging semantic options, if at
7988 least one user action succeeds but a later one cuts the parse, then
7989 destroy the semantic value before returning rather than leaking it.
7990 (yyresolveStates): If a user action cuts the parse and thus
7991 yyresolveValue fails, ignore the (unset) semantic value rather than
7992 corrupting the yyGLRState, and empty the semantic options list since
7993 the user actions should have called all necessary destructors.
7994 Simplify code with YYCHK.
7995 * tests/glr-regression.at (Corrupted semantic options if user action
7996 cuts parse): New test case.
7997 (Undesirable destructors if user action cuts parse): New test case.

8122 Use increment_rule_length rather than incrementing it by hand.
8123 (adjust_location, handle_syncline): Diagnose overflow.

8239 `if (YYID (N))' to pacify lint.
8241 2005-12-21 Akim Demaille <akim@epita.fr>

8264 * djgpp/config.sed: Replace every occurence of the file name
8265 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

8295 sed out the final state number.
8297 Work around portability problem on Solaris 10: flex-generated
8298 files include <stdio.h> before <config.h>, which messes up
8299 because the latter defines __EXTENSIONS__. Address the problem
8300 by creating two new little files that include <config.h> first,
8301 then include the flex-generated files. Rewrite everyone else
8302 to include <config.h> first, as well.
8303 * lib/timevar.c: Always include "config.h".

8351 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
8353 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.

8378 * data/yacc.c: Say "parser skeleton" rather than "file", since
8379 it's no longer just a file.
8380 * data/glr.c: Grant a special exception for C GLR parsers, that
8381 reads like the already-existing exception for C LALR(1) parsers.

8551 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Pass
8553 * data/glr.c (YY_SYMBOL_PRINT, yydestroyGLRState): Adjust.
8554 * data/yacc.c (b4_Pure_if): Rename as...

8556 (YY_SYMBOL_PRINT, yyparse): Adjust.
8557 * doc/bison.texinfo: Formatting changes.
8559 2005-10-21 Akim Demaille <akim@epita.fr>
8561 Finish the transition config -> build-aux.
8562 * configure.ac, Makefile.am: Use build-aux.
8563 * config/prev-version, config/announce-gen, config/Makefile.am:
8565 * build-aux/prev-version, build-aux/announce-gen,
8566 * build-aux/Makefile.am: here.
8568 2005-10-14 Akim Demaille <akim@epita.fr>
8570 * examples/calc++/test: Use set -x only when VERBOSE.
8572 2005-10-13 Paul Eggert <eggert@cs.ucla.edu>
8574 * NEWS: Bison now warns if it finds a stray `$' or `@' in an action.

8577 2005-10-13 Akim Demaille <akim@epita.fr>
8579 * src/scan-skel.l: Output the base name parts of the parser and
8581 * tests/output.at (AT_CHECK_OUTPUT): Support subdirectories, and
8583 Use this to exercise C++ outputs in subdirs.
8584 Reported by Oleg Smolsky.
8586 2005-10-12 Paul Eggert <eggert@cs.ucla.edu>
8588 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
8589 __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
8590 Problem reported by John P. Hartmann.
8591 * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
8594 2005-10-12 Akim Demaille <akim@epita.fr>

8604 * data/location.cc (initial_column, initial_line): Remove.
8605 All uses replaced by 0 and 1.
8606 * src/scan-gram.l (gram_wrap): Redefine to avoid bug in flex 2.5.31
8607 that xlc complains about.
8608 * src/scan-skel.l (skel_wrap): Likewise.
8609 * data/c.m4 (b4_c_function_def): Look at __STDC_VERSION__ as well
8611 * data/yacc.c (YYMODERN_C): New macro, which also looks at
8612 __STDC_VERSION__. Use it everywhere instead of looking at
8613 __STDC__ and __cplusplus.
8615 2005-10-10 Akim Demaille <akim@epita.fr>
8617 * examples/calc++/test: Be quiet unless VERBOSE.
8619 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>

8622 Use YYUSE instead of casting to void.
8623 * data/glr.c (YYUSE): New macro.
8624 (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
8625 Use it instead of rolling our own.
8626 (YYLLOC_DEFAULT, YYCHK, YYDPRINTF, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
8628 Use /*CONSTCOND*/ to suppress lint warnings.
8629 * data/lalr1.cc (YYLLOC_DEFAULT, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
8630 (YY_STACK_PRINT): Use 'false' not '0'.

8639 * data/m4sugar/m4sugar.m4 (_m4_map): New macro.
8640 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
8642 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
8644 Undo the parts of the unlocked-I/O change that substituted
8645 putc or puts for printf. This might hurt performance a bit,
8646 but some people prefer the printf style.
8647 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
8648 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

8669 unused-variable warnings.
8671 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>
8673 * Makefile.am: DJGPP specific files added to EXTRA_DIST.
8675 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
8677 Use unlocked I/O for a minor performance improvement on hosts like
8678 GNU/Linux and Solaris that support unlocked I/O. The basic idea
8679 is to use the gnlib unlocked-io module, and to prefer putc and
8680 puts to printf when either will work (since the latter doesn't
8681 come in an unlocked flavor).
8682 * bootstrap (gnulib_modules): Add unlocked-io.
8683 * data/c.m4 (yysymprint): Prefer puts and putc to printf.

8701 * src/system.h: Include unlocked-io.h rather than stdio.h.
8703 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
8704 this confuses xgettext.

8723 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>,
8724 Akim Demaille <akim@epita.fr>
8726 Make sure -odir/foo.cc creates dir/location.hh etc.

8748 * lib/subpipe.c: New function end_of_output_subpipe() added
8749 to allow support for non-posix systems. This is a no-op function
8752 * lib/subpipe.h: New function end_of_output_subpipe() added
8753 to allow support for non-posix systems. This is a no-op function
8756 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
8757 handle the lack of pipe/fork functionality on non-posix systems.

8780 filename type is defined by the user.
8781 Forward declation location and position before the pre-prologue.

8794 * data/lalr1.cc (stack.hh, location.hh): Include earlier.
8795 (parser::token): New, from the moved free definition of tokens.
8796 (parser::semantic_value): Now a full definition instead of an
8797 indirection to YYSTYPE.
8798 (b4_post_prologue): No longer included in the header file, but
8799 in the implementation file.
8800 * doc/bison.texi (C+ Language Interface): Update.

8825 (yysyntax_error_): Takes the state number as argument.
8826 (yyreduce_print_): Use the argument yyrule, not the former
8829 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
8831 * bootstrap (gnulib_modules): Add verify.
8832 * lib/.cvsignore: Add verify.h.

8841 local variables whose names begin with 'yy'.
8842 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
8843 Trivial changes from Joel E. Denny.
8845 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
8847 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
8848 don't use alloca any more.
8850 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
8851 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
8852 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
8853 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust

8856 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
8858 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
8859 doesn't affect behavior.
8860 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
8862 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
8863 This works a bit better with glibc, if user code has already included
8865 * doc/bison.texinfo (Bison Parser): Document that users can't
8866 arbitrarily use malloc and free for other purposes. Document
8867 that <alloca.h> and <malloc.h> might be included.
8868 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the

8882 (yysyntax_error): New function.
8883 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
8884 multiple syntax errors are reported, and alloca is being used.
8885 Instead, reallocate buffers twice as big each time, so that
8886 we waste at most half the allocated memory. Start with a small
8887 (128-byte) buffer that will suffice in most cases anyway.
8888 Use yysyntax_error to do most of the work.
8890 * doc/bison.texinfo (Error Reporting, Table of Symbols):
8891 yynerrs is the number of errors reported, not the number of
8894 * tests/glr-regression.at (Duplicated user destructor for lookahead):
8895 Mark it as expected to fail.
8896 Cast result of malloc; problem reported by twlevo@xs4all.nl.
8897 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
8898 Don't start user-code symbols with "yy", to avoid name space problems.
8900 2005-09-19 Akim Demaille <akim@epita.fr>
8902 Remove the traits, failed experiment.
8903 It never proved useful, and anyway because of the current
8904 definition, it was not possible to have several specialization of
8905 this traits, making it useless.
8906 * data/lalr1.cc (yy:traits): Remove.
8907 Inline its definitions in the parser class.
8909 2005-09-19 Akim Demaille <akim@epita.fr>

8931 * src/output.c (prepare): Likewise.
8932 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
8933 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
8934 is not defined. This is an awful hack, but it's enough for now.
8935 All callers changed.
8936 * tests/glr-regression-at (make_value): Args are const pointers now,
8937 to avoid GCC warning.
8938 (Duplicated user destructor for lookahead): New test. Currently
8939 skipped. It fails on my host but I'm not sure it'll always fail.
8941 2005-09-16 Akim Demaille <akim@epita.fr>
8943 * src/symtab.h (struct symbol): Declare the printer and destructor
8944 as const, to avoid accidental calls to free.

8955 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
8956 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
8959 2005-09-16 Akim Demaille <akim@epita.fr>
8961 * data/lalr1.cc (yylex_): Remove, inline its code.
8962 (yyreport_syntax_error_): Remove, replaced by...
8963 (yysyntax_error_): this which returns a string and leaves to the
8964 caller the call to the users' error function.
8965 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
8966 Move from members of the parser object...
8967 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
8968 to local variables of the parse function.
8970 2005-09-16 Akim Demaille <akim@epita.fr>
8972 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
8973 since it's in Bison's name space.
8975 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
8977 * data/glr.c (yyresolveValue): Add default case to pacify

8989 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
8991 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
8992 do anything if $@ exists. This reverts part of the 2005-07-07
8995 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
8997 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
8998 contains obsolete information and isn't worth distributing as a
8999 separate file anyway.
9000 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
9001 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
9002 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
9003 (yyparse): Abort if user code uses longjmp to throw an unexpected
9006 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
9008 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
9009 Suggested by twlevo@xs4all.nl.
9011 * data/glr.c (YYCHK1): Do not assume YYE is in range.
9012 This avoids a diagnostic from gcc -Wswitch-enum.
9013 Problem reported by twlevo@xs4all.nl.
9015 * doc/bison.texinfo: Don't use "filename", as per GNU coding
9016 standards. Use "file name" or "file" or "name", depending on
9018 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
9019 not to hack/foo.tab.c.
9020 (Calc++ Top Level): 2nd arg of main is not const.
9021 * data/glr.c: b4_filename -> b4_file_name.
9022 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

9028 * src/files.c: Likewise.
9029 * src/scan-skel.l ("@output ".*\n): Likewise.
9030 * src/files.c (file_name_split): Renamed from filename_split.
9031 * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.
9033 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
9035 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
9036 to accommodate latest gnulib.
9038 * tests/glr-regression.at (Duplicate representation of merged trees):
9039 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
9041 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
9044 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
9046 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
9047 All uses changed. Invoke user destructor after an error during a
9048 split parse (trivial change from Joel E. Denny).
9050 * tests/glr-regression.at
9051 (User destructor after an error during a split parse): New test case.
9052 Problem reported by Joel E. Denny in:
9053 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
9055 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
9057 * README-cvs: Give URLs for recommended tools.
9058 Mention Gzip version problem, and bootstrapping issues.
9059 Remove troubleshooting section, as it's somewhat obsolete.
9061 * bootstrap (no_cache): New var, to accommodate different wget
9062 variants. Use it instead of '-C off'. Problem reported by
9065 * data/glr.c (yydestroyStackItem): New function.
9066 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
9067 debugging information. Problem reported by Joel E. Denny.
9069 2005-08-25 Akim Demaille <akim@epita.fr>
9071 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
9073 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>

9076 Don't invoke destructor on unresolved entries.
9077 * tests/glr-regression.at
9078 (User destructor for unresolved GLR semantic value): New test case.
9079 Problem reported by Joel E. Denny in:
9080 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
9082 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
9084 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
9086 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
9087 lib-prefix.m4, po.m4.
9089 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
9090 in yydestruct diagnostic, since it might not be an error.
9091 Problem reported by Joel Denny near end of
9092 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9093 * data/lalr1.cc (yyerturn): Likewise.
9094 * data/yacc.c (yyreturn): Likewise.
9095 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
9097 * src/files.c: Remove obsolete FIXME comment.
9099 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
9100 with the other templates, and to fix bogus run-on messages such
9101 as the one reported at the end of
9102 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9103 All callers changed to avoid the newline.
9104 (yyprocessOneStack): Output two lines rather than one, to accommodate
9105 the above change. This changes the debug output format slightly.
9107 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
9108 reported by Joel E. Denny in
9109 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
9111 * tests/glr-regression.at (Duplicate representation of merged trees):
9112 New test, from Joel E. Denny in:
9113 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
9114 * THANKS: Add Joel E. Denny.
9116 * configure.ac (AC_INIT): Bump to 2.0c.
9118 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
9120 * NEWS: Version 2.0b.
9122 * Makefile.am (SUBDIRS): Put examples before tests, so that
9123 "make check" doesn't finish with "All 1 tests passed".
9125 * tests/regression.at (Token definitions): Don't rely on
9126 AT_PARSER_CHECK for data that contains backslashes. It currently
9127 uses 'echo', and 'echo' isn't portable if its argument contains
9128 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
9129 that the byte '\0xff' is not printable in the C locale; it is,
9130 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
9131 not printable, so use '\0x81' to test.
9133 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
9134 version of GCC, since the macro is used with non-GCC compilers.
9136 Fix core dump reported by Pablo De Napoli in
9137 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
9138 * tests/regression.at (Invalid inputs with {}): New test.
9139 * src/parse-gram.y (token_name): Translate type before using
9142 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
9143 the user's name space. All uses changed to __attribute__
9145 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
9146 Add __attribute__ ((__noreturn__)).
9148 * etc/clcommit: Remove. We weren't using it, and it failed
9149 "make maintainer-distcheck".
9150 * Makefile.maint: Merge from coreutils.
9151 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
9152 (syntax-check-rules): Change list of rules as described below.
9153 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
9154 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
9155 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
9156 (sc_trailing_space): New rules.

9159 (sc_space_tab, sc_error_exit_success, sc_changelog):
9160 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
9161 (makefile-check, po-check, author_mark_check):
9162 (makefile_path_separator_check, copyright-check):
9163 Use grep -n, to make it easier to find violations.
9164 Use CVS_LIST and CVS_LIST_EXCEPT.
9165 (header_regexp, h_re): Remove.
9167 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
9168 (my-distcheck): Use more-modern GCC flags.
9169 (signatures, %.asc): Remove.
9170 (rel-files, announcement): Remove signatures.
9171 Restore old updating code, even though we don't use it, so
9172 that we're the same as coreutils.
9173 (alpha, beta, major): Depend on news-date-check.
9174 Make the upload commands.
9176 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
9177 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
9178 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
9179 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
9180 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
9181 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
9182 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
9183 * tests/sets.at: Likewise.
9185 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
9186 we comment out the Autoconf version number.
9187 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
9188 it's error-prone and "make maintainer-distcheck" rejects it.
9190 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
9191 Indent calls to "error" to pacify "make maintainer-distcheck",
9192 when the calls are not intended to be translated.
9193 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
9195 * src/Makefile.am (DEFS): Use +=, to pacify
9196 "make maintainer-distcheck".
9197 (bison_SOURCES): Add scan-skel.h.
9198 (sc_tight_scope): New rule, from coreutils.
9200 * src/files.c (src_extension, header_extension):
9201 Now static, not extern.
9202 * src/getargs.c (short_options): Likewise.
9203 * src/muscle_tab.c (muscle_table): Likewise.
9204 * src/parse-gram.y (current_class, current_type, current_prec):
9206 * src/reader.c (grammar_end, previous_rule_end): Likewise.
9207 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
9208 * src/main.c (main): Cast bindtextdomain and textdomain calls to
9209 void, to avoid warning when NLS is disabled.
9210 * src/output.c: Include scan-skel.h.
9211 (scan_skel): Remove decl, since scan-skel.h does this.
9213 Indent calls to "error" to pacify "make maintainer-distcheck".
9214 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
9215 * src/reader.h (gram_end, gram_lineno): New decls to pacify
9216 "make maintainer-distcheck".
9217 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
9218 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
9219 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
9220 (skel_lex_destroy, scan_skel): Move these decls to...
9221 * src/scan-skel.h: New file.
9222 * src/uniqstr.c (uniqstr_assert):
9223 Indent calls to "error" to pacify "make maintainer-distcheck".
9225 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
9228 * tests/torture.at: Revamp to avoid misuse of atoi that
9229 "make maintainer-distcheck" complained about.
9231 * examples/extexi (message): Don't print a message more than once,
9232 and omit line-number decoration that makes Emacs compile think
9233 that informative messages are worth worrying about.
9235 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
9237 * configure.ac: Update version number.
9239 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
9241 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
9242 autogenerated by the maintainer.
9243 * examples/calc++/.cvsignore: Add *.yy.
9245 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
9246 * lib/bitset_stats.c (bitset_stats_init): Likewise.
9247 * lib/bitsetv.c (bitsetv_alloc): Likewise.
9249 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
9251 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
9252 from maintainer-distcheck about casting the argument of 'free'.
9254 * NEWS: Mention recent yytname changes.
9255 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
9257 * bootstrap: For translations that have not yet been upgraded to
9258 the new runtime-po domain, prime the pump by extracting the
9259 relevant strings from the obsolete translations. This code can be
9260 removed once the bison-runtime domain has been translated by each
9263 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
9264 now that token names are already quoted.
9266 Fix problem reported by Anthony Heading.
9267 * data/glr.c (YYTOKEN_TABLE): New macro.
9268 (yytname): Define if YYTOKEN_TABLE.
9269 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
9270 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
9271 (YYERROR_VERBOSE): Define the same way the other skeletons do.
9272 * src/output.c (prepare_symbols): Output token_table_flag.
9274 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
9276 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
9277 again if the first call fails.
9279 * data/glr.c (yytnamerr): New function.
9280 (yyreportSyntaxError): Use it to dequote most string literals.
9281 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
9282 with other skeletons. All uses changed.
9283 (yytnameerr_): New function.
9284 (yyreport_syntax_error): Use it to dequote most string literals.
9285 * data/yacc.c (yytnamerr): New function.
9286 (yyerrlab): Use it to decode most string literals.
9287 * doc/bison.texinfo (Decl Summary, Calling Convention):
9288 Clarify quoting convention of yytname.
9289 * src/output.c (prepare_symbols): Quote all names. This undoes
9290 the 2005-04-17 change, which is now accomplished (mostly) via
9291 changes in the parsers as described above.
9292 * tests/regression.at (Token definitions, Web2c Actions):
9293 Undo most 2005-04-17 change here, too.
9295 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
9297 Fix more problems reported by twlevo@xs4all.nl.
9298 * tests/cxx-type.at: Don't pipe output of ./types through sed to
9299 remove trailing spaces. This loses the exit status of ./types,
9300 and isn't needed since ./types shouldn't be emitting trailing
9302 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
9303 as the stack isn't valid in that case.
9305 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
9306 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
9307 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
9308 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
9310 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
9311 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
9312 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
9315 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
9316 overly-picky compilers that reject 'char *foo = "bar";'.
9318 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
9319 to FILE * parameter, not to stderr. This fixes a typo introduced
9320 in the 2005-07-12 change.
9322 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
9323 warnings from GCC 4.
9325 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
9326 (yyglrShiftDefer, yysplitStack):
9327 Remove unused parameters b4_pure_formals. All uses changed.
9328 (yyglrShift): Remove unused parameters b4_user_formals.
9330 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
9332 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
9334 Destructor cleanups and regularization among the three skeletons.
9335 * NEWS: Document the behavior changes.
9336 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
9337 stack before failing, as the cleanup code will do it for us now.
9338 * data/lalr1.cc (yyerrlab): Likewise.
9339 * data/glr.c (yyparse): Pop everything off the stack before
9340 freeing it, so that destructors get called properly.
9341 * data/lalr1.cc (yyreturn): Likewise.
9342 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
9343 This is more consistent.
9344 * doc/bison.texinfo (Destructor Decl): Mention more reasons
9345 why destructors might be called. 1.875 -> 2.1.
9346 (Destructor Decl, Decl Summary, Table of Symbols):
9347 Some English-language cleanups for %destructor.
9348 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9349 Add output line for destructor of start symbol.
9350 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
9351 because of that same extra output line.
9353 * NEWS: Document minor wording changes in diagnostics of
9354 Bison-generated parsers.
9355 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
9356 Remove unused formals. All uses changed.
9357 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
9358 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
9359 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
9360 Rename yyoverflowab to yyexhaustedlab.
9361 When memory exhaustion occurs during syntax-error reporting,
9362 report it separately rather than in a single diagnostic; this
9364 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
9365 (Memory Exhausted): Renamed from Parser Stack Overflow.
9366 Revamp wording slightly to prefer "memory exhaustion".
9367 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
9369 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
9371 Add i18n support to the GLR skeleton. Partially fix the C++
9372 skeleton; a C++ expert needs to finish this. Remove debugging
9373 msgids; there's little point to having them translated, since they
9374 can be understood only by someone who can read the
9375 (English-language) source code.
9377 Generate runtime-po/bison-runtime.pot automatically, so that we
9378 don't have to worry about garbage getting in that file. We'll
9379 make sure after the next official release that old msgids don't
9381 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
9383 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
9385 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
9386 Fix typos in explanations of the runtime file.
9387 * bootstrap: Change gettext keyword from YYI18N to YY_.
9388 Use standard Makefile.in.in in runtime-po, since we'll arrange
9389 for backward-compatible bison-runtime.po files in a different way.
9390 * data/glr.c (YY_): New macro, from yacc.c.
9391 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
9392 Translate messages intended for users.
9393 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
9394 the wording in the other skeletons. We don't know that the memory
9396 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
9397 Use same method that yacc.c uses.
9398 Don't translate debugging messages.
9399 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
9400 it doesn't work (yet), and requires C++ expertise to fix.
9401 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
9402 Move defn to a more logical place, to be consistent with other
9404 Don't translate debugging messages.
9405 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
9406 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
9407 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
9408 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
9410 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
9411 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
9413 * tests/glr-regression.at (Badly Collapsed GLR States):
9415 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
9416 yylex should return 0 at EOF rather than aborting.
9418 Improve tests for stack overflow in GLR parser.
9419 Problem reported by twlevo@xs4all.nl.
9420 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
9422 (yyStackOverflow): Just longjmp, but with value 2 so that caller
9423 can handle the problem.
9424 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
9425 (yyparse): New local variable yyresult to record the result.
9426 Use result of setjmp to set it, rather than storing itinto
9428 (yyDone): Remove label.
9429 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
9430 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
9431 if YYABORT is used).
9432 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
9433 yyparse status; put status > 1 into diagnostic.
9434 Check that status==2 works.
9435 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
9436 Use exit status 3 for failure to open (which shouldn't happen).
9438 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
9440 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
9441 1 on syntax error; just let yyparse do its thing.
9442 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
9443 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
9444 (Exploding the Stack Size with Alloca):
9445 (Exploding the Stack Size with Malloc):
9446 Expect exit status 2, not 1, since the parser is supposed to blow
9447 its stack. Problem reported by twlevo@xs4all.nl.
9449 * data/glr.c (yyparse): Don't assume that the initial calls
9450 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
9451 Print a stack-overflow message and fail instead.
9452 Initialize the line-number information before creating the stack,
9453 so that the stack-overflow message can report line zero safely.
9455 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
9457 Fix problems reported by twlevo@xs4all.nl.
9458 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
9459 (yyuserMerge): Provide a default case if b4_mergers is empty.
9460 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
9461 * tests/glr-regression.at
9462 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
9463 Add casts to pacify C++ compilers.
9464 * tests/glr-regression.at (Improper merging of GLR delayed action
9465 sets): Declare yylex before using it.
9466 * tests/Makefile.am (maintainer-check-g++): Fix a stray
9467 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
9468 test for valgrind; valgrind is independent of g++.
9469 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
9470 for compatibility with POSIX 1003.1-2001 (if running coreutils).
9471 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
9472 Use a destructor, so that we can expand the stack. Change
9473 YYSTYPE to char * so that we can free it. Cast result of malloc.
9475 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9477 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
9478 a valgrind failure. Problem reported by twlevo@xs4all.nl.
9480 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
9482 * PACKAGING: New file, suggested by Bruno Haible and taken from
9483 similar wording in gettext's PACKAGING file.
9484 * NEWS: Mention PACKAGING.
9485 * Makefile.am (EXTRA_DIST): Add PACKAGING.
9487 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
9489 * NEWS: Document recent i18n improvements.
9490 * bootstrap: Get runtime translations into runtime-po.
9491 Create runtime-po files automatically, if possible.
9492 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
9493 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
9494 does not infringe on the user's name space.
9495 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
9496 * doc/bison.texinfo (Internationalization): Revamp the English
9497 and Texinfo syntax a bit, to try to make it clearer.

9510 * runtime-po/Makevars: Likewise.
9511 * runtime-po/LINGUAS: Likewise.
9512 * runtime-po/de.po: Likewise; we will rely on the translation project
9513 to maintain this, so "bootstrap" should get it.
9514 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
9516 * src/main.c (main): Bind the bison-runtime domain, too.
9518 2005-07-12 Bruno Haible <bruno@clisp.org>
9520 * data/yacc.c: Include <libintl.h> when NLS is enabled.
9521 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
9522 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
9523 * runtime-po: New directory.
9524 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
9525 $(DOMAIN).pot-update rule, so that old messages are never dropped.
9526 * runtime-po/Rules-quot: New file, copied from po/.
9527 * runtime-po/quot.sed: Likewise.
9528 * runtime-po/boldquot.sed: Likewise.
9529 * runtime-po/en@quot.header: Likewise.

9548 (Internationalization): New section.
9550 2005-07-12 Akim Demaille <akim@epita.fr>
9552 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
9553 for consistency with the rest of the code.
9554 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
9557 2005-07-12 Akim Demaille <akim@epita.fr>
9559 * src/parse-gram.y: Use %printer instead of YYPRINT.
9561 2005-07-12 Akim Demaille <akim@epita.fr>

9575 and Pennello's paper.
9577 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
9579 * data/yacc.c (yyparse): Undo previous patch. Instead,
9580 set yylsp[0] and yyvsp[0] only if the initial action
9581 sets yylloc and yylval, respectively.
9583 * data/yacc.c (yyparse): In the initial action, set
9584 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
9585 This avoids the use of undefined variables if the initial
9586 action does not set yylloc and/or yylval.
9588 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
9590 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
9591 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
9592 Remove from CVS. These files are automatically generated.
9593 * examples/extexi: Clarify that this file is now part of Bison,
9594 not GNU M4, and that it works with any POSIX-compatible Awk.
9595 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
9596 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
9597 so that we also get calc++-parser.yy. Geneate it.
9598 Use $(AWK), not gawk, since any conforming Awk will do.
9599 Put comment before action, since older 'make' can't handle comment
9601 $(BUILT_SOURCES): List all built sources, not just some of them.
9602 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
9603 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
9604 $($(calc_sources_generated)): Remove unnecessary test for existence
9605 of target. (This had a shell syntax error anyway; a stray "x".)
9606 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
9608 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
9610 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
9611 implied by the other modules.
9613 2005-07-06 Akim Demaille <akim@epita.fr>
9615 Bind examples/calc++ to the package.

9624 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
9626 * data/glr.c (yyFail): Drastically simplify; since the format argument
9627 never had any % directives, we can simply pass it to yyerror.
9628 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
9629 be modified later, as that is the usual style in glr.c.
9630 Problems reported by Paul Hilfinger.
9632 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
9633 and size overflow errors.
9634 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
9635 in case the user prolog sets feature-test macros like _GNU_SOURCE.
9636 (YYSIZEMAX): New macro.
9637 (yystpcpy): New function, taken from yacc.c.
9638 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
9639 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
9640 so that we don't have to maintain their signatures.
9641 (yyFail): Check for buffer overflow, by using vsnprintf rather
9642 than vsprintf. Allocate a bigger buffer if possible.
9643 Report an error if buffer allocation fails.
9644 (yyStackOverflow): New function.
9645 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
9646 the initialization was successful. It might fail if storage was
9648 (yyexpandGLRStack): Add more checks for storage allocation failure.
9649 Use yyStackOverflow to report failures.
9650 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
9651 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
9652 Don't assume stack number fits in int.
9653 (yysplitStack): Check for storage allocation failure.
9654 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
9655 can print diagnostics on storage allocation failure. All callers
9657 (yyresolveValue): Use yybool for boolean.
9658 (yyreportSyntaxError): Check for size-calculation overflow.
9659 This code is taken from yacc.c.
9660 (yyparse): Check for storage allocation errors when allocating
9663 2005-07-05 Akim Demaille <akim@epita.fr>
9665 Extract calc++ from the documentation.
9666 * doc/bison.texinfo (Calc++): Add the extraction marks.

9668 Separate the different paragraph of a file with empty lines.
9669 * examples/Makefile: Use it to extract the whole calc++ example.
9671 2005-06-24 Akim Demaille <akim@epita.fr>
9673 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
9676 2005-06-22 Akim Demaille <akim@epita.fr>
9678 * doc/bison.texinfo (C++ Language Interface): First stab.
9679 (C++ Parsers): Remove.
9681 2005-06-22 Akim Demaille <akim@epita.fr>
9683 * data/lalr1.cc (yylex_): Honor %lex-param.
9685 2005-06-22 Akim Demaille <akim@epita.fr>
9687 Start a set of simple examples.

9690 * examples/calc++/calc++-parser.yy,
9691 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
9692 * examples/calc++/compile, examples/calc++/test: New.
9694 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
9696 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
9697 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
9698 which stems from the 2005-05-27 patch.
9700 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
9702 * data/glr.c: Modify treatment of unused parameters to permit use
9703 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
9705 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
9707 Fix infringement on user name space reported by Janos Zoltan Szabo.
9708 * data/yacc.c (yyparse): strlen -> yystrlen.
9710 2005-05-30 Akim Demaille <akim@epita.fr>
9712 * data/lalr1.cc (_): New.
9713 Translate the various messages.
9715 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
9717 Fix infringement on user name space reported by Bruno Haible.
9718 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
9719 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
9720 the user's name space.
9721 (alloca): Include <stdlib.h> to get it, if it's not built in.
9722 (YYMALLOC, YYFREE): Define only if needed.
9723 (malloc, free): Declare, but only if needed, as this infringes on
9724 the user name space.
9726 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
9728 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
9729 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
9731 * lib/ebitset.c (min, max): Undef before defining.
9732 * lib/vbitset.c (min, max): Likewise.
9733 * lib/subpipe.c (create_subpipe): Save local variables in case
9734 vfork clobbers them.
9736 2005-05-24 Bruno Haible <bruno@clisp.org>
9738 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
9739 error message syntax used by gcc-4.0.
9741 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
9743 * README: Mention m4 1.4.3. Remove obsolete advice about
9744 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
9746 * bootstrap: Remove workaround for problem I encountered with
9747 gettext 0.14.1; it seems to be fixed now.
9749 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
9751 * NEWS: Version 2.0a.
9753 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
9754 the previous change.
9756 Various maintainer cleanups.
9757 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
9758 conftest*, for benefit of CVS commands run at the same time as
9759 "configure". Add build-aux, since "bootstrap" now creates it and
9761 * Makefile.cfg (move_if_change): Remove.
9762 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
9763 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

9773 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
9774 ylwrap. These files now go into build-aux.
9775 * config/move-if-change: Remove.
9776 * config/prev-version.txt: Bump from 1.75 to 2.0.
9778 * bootstrap: Add stdio-safer, unistd-safer modules.

9782 fopen-safer.c, stdio-safer.h, unistd-safer.h.
9783 * lib/subpipe.c: Include "unistd-safer.h".
9784 (create_subpipe): Make sure all the newly-created
9785 file descriptors are > 2, so that diagnostics don't
9786 get sent down them (which might cause Bison to hang, in theory).
9787 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
9788 * src/files.c (xfopen): Use fopen_safer, not fopen.
9790 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
9791 yesterday's yacc.c fix.

9800 don't set yychar to EMPTY.
9801 (yyoverflowlab): Don't call destructor.
9802 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
9803 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
9804 since we no longer output the message "discarding lookahead token
9807 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9809 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
9810 fix a small glitch in debugging output.
9811 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
9812 after YY_SYMBOL_PRINT where needed.
9814 (struct yyGLRState): Add some comments.
9815 (struct yySemanticOption): Add some comments.
9816 (union yyGLRStackItem): Add comment.

9866 Problem reported by Ralf Menzel.
9868 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
9870 * tests/actions.at: Test that stack overflow invokes destructors.
9871 From Marcus Holland-Moritz.
9872 * data/yacc.c (yyerrlab): Move the code that destroys the stack
9874 (yyreturn): to here. That way, destructors are called properly
9875 even if the stack overflows, or the user calls YYACCEPT or
9876 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
9877 (yyoverflowlab): Destroy the lookahead.
9879 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>

9885 * NEWS: Bison-generated C parsers no longer quote literal strings
9886 associated with tokens.
9887 * src/output.c (prepare_symbols): Don't escape strings,
9888 since users don't want to see C escapes.
9889 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
9891 * tests/input.at (Torturing the Scanner): Likewise.
9892 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
9894 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
9896 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
9897 the data size is known to be too small and we can't increase it.
9898 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
9900 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
9902 * src/parse-gram.y: Include quotearg.h.
9903 (string_as_id): Quote $1 before using it as a key, since the
9904 lexer no longer quotes it for us.
9905 (string_content): Don't strip quotes, since lexer no longer
9907 * src/scan-gram.l: Include quotearg.h.
9909 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
9910 a key, since the rest of the lexer doesn't quote it.
9911 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
9912 * tests/regression.at (Token definitions): Check for backslashes
9915 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
9916 (YYSIZE_T): Define to unsigned long int when using an older compiler.
9917 (yyparse): Revamp code to generate long syntax error message, to
9918 make it easier to translate, and to avoid problems with arithmetic
9919 overflow. Change "virtual memory" to "memory" in diagnostic, since
9920 we don't know whether the memory is virtual.
9922 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
9924 * NEWS: Bison-generated C parsers now use the _ macro to
9926 * data/yacc.c (_) [!defined _]: New macro.
9927 All English strings wrapped inside this macro.
9928 * doc/bison.texinfo (Bison Parser): Document _.
9929 * po/POTFILES.in: Include src/parse-gram.c, since it now
9930 includes translateable strings that parse-gram.y doesn't.
9932 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
9934 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
9935 reverting the 2004-10-11 change to this function.
9936 (symbol_check_alias_consistency): Don't call symbol_type_set
9937 if the type name is already correct.
9938 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
9940 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
9942 * tests/regression.at (Token definitions): Don't use a token named
9943 c, as that generates a "#define c ..." that runs afoul of buggy
9944 stdlib.h that uses the identifier c as a member of struct
9945 drand48_data. Problem reported by Horst Wente.
9947 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
9949 * bootstrap: Change translation URL from
9950 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
9951 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
9952 redirection glitches. Problem reported by twlevo@xs4all.nl.
9954 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
9956 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
9957 after operands; POSIX says this isn't portable for the c99 command.
9959 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
9961 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
9962 immediately if a data overrun has occurred; this may help us track
9963 down what may be a spurious failure on MacOS.
9965 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
9967 Respond to problems reported by twlevo@xs4all.nl.
9969 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
9971 * src/vcg.h: Comment fix.
9972 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
9973 (G_CMAX): Change to -1 instead of INT_MAX.
9975 * data/yacc.c (yyparse): Omit spaces before #line.
9977 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
9979 * src/tables.c (state_number_to_vector_number): Put it inside an
9980 "#if 0", since it's not currently used. Problem reported by
9983 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
9985 * src/output.c (escaped_output): Renamed from
9986 escaped_file_name_output, since we now use it for symbol tags as
9987 well. All uses changed.
9988 (symbol_destructors_output, symbol_printers_output):
9989 Escape symbol tags too.
9990 Problem reported by Matyas Forstner in
9991 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
9993 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
9995 * src/output.c (user_actions_output, token_definitions_output,
9996 symbol_destructors_output, symbol_printers_output): Likewise.
9997 * src/reader.c (prologue_augment): Likewise.
9998 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
10000 * src/vcg.c (output_edge): Don't quote linestyle arg.
10001 Problem reported by twlevo@xs4all.nl.
10003 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
10005 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
10006 example, reported by Derek M Jones. Also, make the example even
10007 more outrageous, to better illustrate how bad the problem is.
10009 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
10011 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
10012 putsym. Typo reported by Sebastian Piping.
10014 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10016 * doc/bison.texinfo (Language and Grammar): some -> same
10017 (Epilogue): int he -> in the
10018 Typos reported by Sebastian Piping via Justin Pence.
10020 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
10022 * tests/glr-regression.at (Improper handling of embedded actions
10023 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
10024 embedded actions and $-N in GLR parsers", work around an Autoconf bug
10025 with dollar signs in test names.
10026 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
10027 for a similar reason.
10029 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
10031 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
10032 wants to redefine G_VIEW.
10034 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
10036 * src/vcg.c (get_view_str): Remove case for normal_view.
10037 Problem reported by twlevo@xs4all.nl.
10039 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
10041 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
10042 Problem reported by twlevo@xs4all.nl.
10044 * doc/bison.texinfo: Change @dircategory from "GNU programming
10045 tools" to "Software development". Requested by Richard Stallman
10048 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
10050 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
10051 Problem reported by twlevo@xs4all.nl.
10053 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
10055 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
10056 keyword; it's not needed with modern compilers, and it doesn't
10057 affect correctness with older compilers. Suggested by
10060 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
10062 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
10063 gcc -Wswitch-default.
10064 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
10065 * data/yacc.c (yyparse): Likewise.
10067 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
10069 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
10070 already. Let config.h define any nonstandard values.
10072 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
10074 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
10075 for the benefit of slower hosts. Problem reported by
10076 Nelson H. F. Beebe.
10078 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
10080 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
10081 being defined and not used.
10082 * data/lalr1.cc (yyparse): Likewise.
10083 Use "if (false)" rather than "if (0)".
10085 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
10087 * TODO: Mention that we should allow NUL bytes in tokens.
10089 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
10091 * src/scan-skel.l (<<EOF>>): Don't close standard output.
10092 Problem reported by Hans Aberg.
10094 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
10096 * src/getargs.c (version): Happy new year; update overall
10097 program copyright date from 2004 to 2005.
10099 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
10100 Problem reported by Hans Aberg.
10101 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
10102 (Output file names.): Add a test for the case when standard output
10105 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
10107 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
10108 to fix an oversight in the Bison 2.0 manual.
10110 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
10112 * NEWS: Version 2.0. Reformat the existing news items since
10113 1.875, so that related items are grouped together.
10114 * configure.ac (AC_INIT): Bump version to 2.0.
10115 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
10117 * tests/torture.at (Exploding the Stack Size with Alloca): Set
10118 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
10119 otherwise, we're not testing alloca. Unfortunately there's no
10120 simple way to consult HAVE_ALLOCA here.
10122 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
10125 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
10126 hand. This avoids a warning about comparing int to size_t when
10127 GCC warnings are enabled.
10129 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
10131 * NEWS: Bison-generated parsers no longer default to using the
10132 alloca function (when available) to extend the parser stack, due
10133 to widespread problems in unchecked stack-overflow detection.
10134 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
10135 responsibility to set it to a positive value. This lets the user
10136 specify a value that is not a preprocessor constant.
10137 * data/yacc.c (YYMAXDEPTH): Likewise.
10138 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
10139 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
10140 to be a compile-time constant. However, explain the constraints on it.
10141 Also, explain the constraints on YYINITDEPTH.
10142 (Table of Symbols): Explain that alloca is no longer the default.
10143 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
10146 * doc/bison.texinfo (Location Default Action): Mention that n must
10147 be zero when k is zero. Suggested by Frank Heckenbach.
10149 2004-12-22 Akim Demaille <akim@epita.fr>
10151 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
10152 (parser::state_type, parser::semantic_type, parser::location_type):
10153 Private, not public.
10154 (parser::parse): Return ints, not bool.
10155 Returning a bool introduces a problem: 0 corresponds to false, and
10156 it seems weird to return false on success. Returning true changes
10157 the conventions for yyparse.
10158 Alternatively we could return void and send an exception.
10159 There is no clear consensus (yet?).
10160 (state_stack, semantic_stack, location_stack): Rename as...
10161 (state_stack_type, semantic_stack_type, location_stack_type): these.
10162 Private, not public.
10163 * tests/c++.at: New.
10164 * tests/testsuite.at, tests/Makefile.am: Adjust.
10166 2004-12-21 Akim Demaille <akim@epita.fr>
10168 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
10170 2004-12-21 Akim Demaille <akim@epita.fr>
10172 Don't impose std::string for filenames.
10174 * data/lalr1.cc (b4_filename_type): New.
10175 (position::filename): Use it.
10176 (parser.hh): Move the inclusion of stack.hh and location.hh below
10177 the user code, so that needed headers for the filename type can be
10179 Forward declare them before the user code.
10180 * tests/Makefile.am (check-local, installcheck-local): Pass
10181 TESTSUITEFLAGS to the TESTSUITE.
10183 2004-12-20 Akim Demaille <akim@epita.fr>
10185 Use more STL like names: my_class instead of MyClass.
10187 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
10188 (SemanticStack, SemanticType, StateStack, StateType)
10189 (TokenNumberType, Stack, Slice, Traits, Parser::location)
10190 (Parser::value): Rename as...
10191 (location_stack, location_type, rhs_number_type, semantic_stack)
10192 (semantic_type, state_stack, state_type, token_number_type, stack)
10193 (slice, traits, parser::yylloc, parser::yylval): these.
10195 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
10197 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
10199 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
10200 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10202 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
10204 Remove uses of 'short int' and 'unsigned short int'. This raises
10205 some arbitrary limits. It uses more memory but nowadays that's
10206 not much of an issue.
10208 This change does not affect the generated parsers; that's a different
10209 task, as some users will want to conserve memory there.
10211 Ideally we should use size_t to represent all object counts, and
10212 something like ptrdiff_t to represent signed differences of object
10213 counts; but that will require more code-cleanup than I have the
10214 time to do right now.
10216 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
10217 Use size_t, not int or short int, to count objects.
10218 * src/closure.c (nritemset, closure): Likewise.
10219 * src/closure.h (nritemset, closure): Likewise.
10220 * src/nullable.c (nullable_compute): Likewise.
10221 * src/print.c (print_core): Likewise.
10222 * src/print_graph.c (print_core): Likewise.
10223 * src/state.c (state_compare, state_hash): Likewise.
10224 * src/state.h (struct state): Likewise.
10225 * src/tables.c (default_goto, goto_actions): Likewise.
10227 * src/gram.h (rule_number, rule): Use int, not short int.
10228 * src/output.c (prepare_rules): Likewise.
10229 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
10230 errs, reductions): Likewise.
10231 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
10233 * src/tables.c (vector_number, tally, action_number,
10234 ACTION_NUMBER_MINIMUM): Likewise.
10235 * src/output.c (muscle_insert_short_int_table): Remove.
10237 2004-12-17 Akim Demaille <akim@epita.fr>
10239 * data/lalr1.cc: Extensive Doxygenation.
10240 (error_): Rename as...
10241 (error): this, since it is visible to the user.
10243 (Parser::message): Now an automatic variable from...
10244 (Parser::yyreport_syntax_error_): here.
10245 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
10247 * tests/input.at: Escape $.
10249 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
10251 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
10252 Parenthesize rhs to avoid obscure problems with mistakes like
10253 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
10254 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10255 b4_rhs_location): Likewise.
10256 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10257 b4_rhs_location): Likewise.
10259 2004-12-16 Akim Demaille <akim@epita.fr>
10261 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
10262 yacc.c: be sure to stay within yycheck_.
10263 * tests/actions.at: Re-enable C++ tests.
10265 2004-12-16 Akim Demaille <akim@epita.fr>
10267 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
10270 2004-12-16 Akim Demaille <akim@epita.fr>
10272 Use #define to handle the %name-prefix.
10274 * data/glr.c, data/yacc.c: Comment changes.
10275 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
10276 so that one can refer to yylex in the parser file, and have it
10277 renamed, as is the case with other skeletons.
10279 2004-12-16 Akim Demaille <akim@epita.fr>
10281 Move lalr1.cc internals into yy*.

10301 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
10303 Fix some problems reported by twlevo at xs4all.
10304 * src/symtab.c (symbol_new): Report an error if the input grammar
10305 contains too many symbols. This is better than calling abort() later.
10306 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
10307 (struct node, struct graph):
10308 Rename member expand to stretch. All uses changed.
10309 (struct graph): Remove member layoutalgorithm. All uses removed.
10310 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
10311 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
10313 (N_STRETCH): Rename from N_EXPAND. All uses changed.
10315 2004-12-15 Akim Demaille <akim@epita.fr>
10317 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
10318 Add more Doxygen comments.
10319 (symprint_, stack_print_, reduce_print_, destruct_, pop)
10320 (report_syntax_error_, translate_): Rename as...
10321 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
10322 (yypop_, yyreport_syntax_error_, yytranslate_): this.
10324 2004-12-15 Akim Demaille <akim@epita.fr>
10326 * data/lalr1.cc (lex_): Rename as...
10328 Move the trace here.
10329 Take the %name-prefix into account.
10330 Reported by Alexandre Duret-Lutz.
10332 2004-12-15 Akim Demaille <akim@epita.fr>
10334 Simplify the C++ parser constructor.
10336 * data/lalr1.cc (debug_): Rename as...
10337 (yydebug_): so that the parser's internals are always in the yy*
10340 (b4_parse_param_decl): Remove the leading comma as it is now only
10341 called as unique argument list.
10342 (Parser::Parser): Remove the constructor accepting a location and
10343 an initial debugging level.
10344 Remove from the other ctor the argument for the debugging level.
10345 (debug_level_type, debug_level, set_debug_level): New.
10347 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
10350 2004-12-15 Akim Demaille <akim@epita.fr>
10352 Remove b4_root related material: failure experiment
10353 (which goal was to allow to derive from a class).
10355 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
10356 definitions and uses.
10358 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
10360 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
10361 not 2, since it's not portable to subtract 1 from the start of an
10362 array. The new item 0 is never set or used. All uses changed.
10364 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
10365 the default definition of YYLLOC_DEFAULT. Problem reported
10366 by Frank Heckenbach.
10368 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
10370 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
10371 the normal case and one for the error case. Just use the
10372 first one uniformly. Problem reported by Frank Heckenbach.
10373 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
10374 use exactly the same macro in both places.
10375 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
10376 so that the normal-case YYRHSLOC works for the error case too.
10378 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
10379 (YYLLOC_DEFAULT): Use the same macro as glr.c.
10380 * doc/bison.texinfo (Location Default Action): Don't claim that
10381 we have an array of locations. Use the same macro for both glr
10382 and lalr parsers. Mention YYRHSLOC. Mention what happens when
10385 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
10387 * HACKING: Update email addresses to send announcements to.
10389 * configure.ac (AC_INIT): Bump version to 1.875f.
10391 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
10393 * NEWS: Version 1.875e.
10394 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
10396 * src/scan-skel.l: Include "complain.h", for "fatal".
10398 * src/relation.h (relation_print, relation_digraph):
10399 Relation sizes are of type relation_node, not size_t (this is
10400 merely a doc fix, since the two types are equivalent).
10401 (relation_transpose): Relation sizes are of type relation_node,
10403 * src/relation.c: Likewise.
10404 (top, infinity): Now of type relation_node, not int.
10405 (traverse, relation_transpose): Use relation_node, not int.
10407 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
10408 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
10409 (yyparse): Remove unused local introduced in 2004-10-25 patch.
10411 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
10412 specifying whether the test should be skipped. Use it tp
10413 specify that the [%defines %skeleton "lalr1.cc"] tests currently
10414 fail on some hosts, and should be skipped.
10416 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
10418 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
10419 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
10420 unless otherwise specified below.
10422 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
10423 to allocate kernel_base, kernel_items, kernel_size, since
10424 they needn't be initialized to 0.
10425 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
10426 * src/closure.c (new_closure): Likewise, for itemset.
10427 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
10428 * src/lalr.c (set_goto_map): Likewise, for temp_map.
10429 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
10430 (build_relations): Likewise for edge, states1, includes.
10431 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
10432 * src/reader.c (packgram): Likewise, for ritem, rules.
10433 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
10434 * src/relation.c (relation_digraph): Likewise for VERTICES.
10435 (relation_transpose): Likewise for new_R, end_R.
10436 * src/symtab.c (symbols_token_translations_init): Likewise for
10437 token_translations.
10438 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
10439 (token_actions): Likewise for yydefact, actrow, conflrow,
10441 (save_column): Likewise for froms[symno], tos[symno].
10442 (goto_actions): Likewise for state_count.
10443 (pack_table): Likewise for base, pos, check.
10444 (tables_generate): Likewise for width.
10446 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
10447 for initial core. Just have a separate core, so we needn't worry
10448 about whether kernel_size and kernel_base are initialized.
10450 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
10451 kernel_size, kernel_items): Remove unnecessary initialization.
10452 * src/conflicts.c (conflicts): Likewise.
10453 * src/derives.c (derives): Likewise.
10454 * src/muscle_tablc (muscle_insert): Likewise.
10455 * src/relation.c (relation_digraph): Likewise.
10456 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
10457 conflrow, conflict_table, conflict_list, table, check):
10460 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
10461 This is because all callers pass unsigned int.
10462 * src/closure.h (new_closure): Likewise.
10464 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
10465 (build_relations): Initialize includes[i] in all cases.
10466 * src/reader.c (packgram): Always initialize rules[ruleno].prec
10467 and rules[ruleno].precsym. Initialize members in order.
10468 * src/relation.c (relation_transpose): Always initialize new_R[i]
10470 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
10472 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
10473 conflict_list[0] was always 0, but now it isn't initialized.
10475 * src/table.c (table_grow): When conflict_table grew, the grown
10476 area wasn't cleared. Fix this.
10478 * lib/.cvsignore: Add strdup.c, strdup.h.
10479 * m4/.cvsignore: Add strdup.m4.
10481 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
10483 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
10484 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
10485 GOTO_NUMBER_MAXIMUM, since we occasionally compute
10486 ngotos + 1 without checking for overflow.
10487 (build_relations): Use END_NODE, not -1, to denote end of edges.
10488 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
10489 build_relations): Use goto_number, not int, for goto numbers.
10490 * src/tables.c (save_column, default_goto): Likewise.
10492 2004-11-23 Akim Demaille <akim@epita.fr>
10494 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
10495 of #defining from yystype.
10496 Don't typedef yystype, C++ does not need it.
10497 This lets it possible to forward declare it as union.
10499 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
10501 * bootstrap (gnulib_modules): Add extensions.
10502 Problem reported by Jim Meyering.
10504 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
10506 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
10507 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
10508 src/system.h, src/tables.c: XFREE -> free, to accommodate
10509 recent change to gnulib xalloc.h.
10510 Problem reported by Jim Meyering.
10512 2004-11-17 Akim Demaille <akim@epita.fr>
10514 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
10516 2004-11-17 Akim Demaille <akim@epita.fr>,
10517 Alexandre Duret-Lutz <adl@gnu.org>
10519 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
10521 (YYCDEBUG): Adjust.
10522 Use it instead of cdebug_.
10523 (Parser::debug_stream, Parser::set_debug_stream): New.
10524 (Parser::symprint_): Define cdebug_ for temporary backward
10526 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
10529 2004-11-17 Akim Demaille <akim@epita.fr>
10531 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
10532 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
10533 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
10534 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
10536 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
10538 * data/glr.c (yyloc_default): Remove; not used.
10539 Problem reported by Frank Heckenbach.
10541 2004-10-25 Akim Demaille <akim@epita.fr>
10543 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
10544 Introduce another definition to address simple location arrays.
10545 (yyGLRStack): New member: yyerror_range.
10546 (yyrecoverSyntaxError, yyparse): Update it.
10547 (yyrecoverSyntaxError): Use it when shifting the error token to
10548 have an accurate range, equivalent to the one computed by both
10549 yacc.c and lalr1.cc.
10550 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
10551 that column numbers start at column 0, as per GNU Coding
10552 Standards, the others tests, and the doc.
10553 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
10554 Adjust to the above change (first column is 0).
10555 And adjust the location of the "<error>", now covering the whole
10558 2004-10-22 Akim Demaille <akim@epita.fr>
10559 and Paul Eggert <eggert@cs.ucla.edu>
10561 Remove some arbitrary limits on goto numbers and relations.
10562 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
10563 initial values, since they're never used.
10564 (set_goto_map): ngotos is now unsigned, so test for overflow
10565 by seeing whether it wraps around to zero.
10566 * src/lalr.h (goto_number): Now size_t, not short int.
10567 (GOTO_NUMBER_MAXIMUM): Remove.
10568 * src/relation.c (relation_print, traverse, relation_transpose):
10569 Check for END_NODE rather than looking at sign.
10570 * src/relation.h (END_NODE): New macro.
10571 (relation_node): Now size_t, not short int.
10573 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
10575 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
10576 keyword, not an identifier. Problem reported by Baron Schwartz in
10577 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
10579 2004-10-11 Akim Demaille <akim@epita.fr>
10581 * src/symtab.c (symbol_check_alias_consistency): Also check
10582 type names, destructors, and printers.
10583 Reported by Alexandre Duret-Lutz.
10584 Recode the handling of associativity and precedence in terms
10585 of symbol_precedence_set.
10586 Accept no redeclaration at all, not even equal to the previous
10588 (redeclaration): New.
10589 Use it to factor redeclaration complaints.
10590 (symbol_make_alias): Don't set the type of the alias, let
10591 symbol_check_alias_consistency do it as for other features.
10592 * src/symtab.h (symbol): Add new member prec_location, and
10594 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
10595 * tests/input.at (Incompatible Aliases): New.
10597 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
10599 .cvsignore fixes to accommodate gnulib changes,
10600 and the practice of naming build directories "_build".
10601 * .cvsignore: Add "_*". Sort.
10602 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
10603 * m4/.cvsignore: Add "*_gl.m4".
10605 2004-10-06 Akim Demaille <akim@epita.fr>
10607 * src/parse-gram.y (add_param): Fix the truncation of trailing
10610 2004-10-05 Akim Demaille <akim@epita.fr>
10612 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
10613 whether the reducion was empty or not. This leaves room to
10614 improve the use of YYLLOC_DEFAULT in such a case.
10615 lalr1.cc is still experimental, so changing this is acceptable.
10616 And finally, there are probably not many users who changed the
10617 handling of locations in GLR, so changing is admissible too.
10619 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
10620 empty reduction, set @$ to an empty location ending the previously
10622 Adjust uses to make sure the code is triggered on empty
10624 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
10625 expected output: empty reductions have empty locations.
10627 2004-09-29 Akim Demaille <akim@epita.fr>
10629 * data/lalr1.cc: Move towards a more standard C++ coding style
10630 for templates: Class < T > -> Class<T>.
10632 2004-09-29 Akim Demaille <akim@epita.fr>
10634 * data/lalr1.cc: Reinstall the former ctor, for sake of
10635 compatibility, but warn it will be removed.
10636 Move towards a more standard C++ coding style (i.e., type *var ->
10639 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
10641 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
10642 since it's less likely to work if NULs are involved in the future.
10644 2004-09-27 Akim Demaille <akim@epita.fr>
10646 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
10648 2004-09-27 Akim Demaille <akim@epita.fr>
10650 * data/lalr1.cc (b4_parse_param_decl_1): New.
10651 (b4_parse_param_decl): Use it to have different names between attribute
10652 and argument names.
10653 (b4_cc_constructor_call): Likewise.
10655 2004-09-24 Akim Demaille <akim@epita.fr>
10657 * src/parse-gram.y (add_param): Strip the leading and trailing
10658 blanks from a formal argument declaration.
10659 (YY_LOCATION_PRINT): New.
10661 2004-09-24 Akim Demaille <akim@epita.fr>
10663 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
10664 after the location.
10666 2004-09-24 Akim Demaille <akim@epita.fr>
10668 * doc/bison.texinfo (Table of Symbols): Sort.
10670 2004-09-21 Akim Demaille <akim@epita.fr>
10672 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
10673 the useless parentheses.
10674 Suggested by Paul Eggert.
10676 2004-09-20 Akim Demaille <akim@epita.fr>
10678 Let the initial-action act on the look-ahead, and use it for the
10679 "initial push" (corresponding to an hypothetical beginning-of-file).
10680 And let lalr1.cc honor %initial-action.
10682 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
10684 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
10685 (Parser::Parser): Remove the ctor that used to initialize it.
10686 (Parser::parse): Like in the other skeletons, issue the "starting
10687 parse" message before any action.
10688 Honor %initial-action.
10689 Initialize the stacks with the lookahead.
10690 * data/yacc.c: Let $$ and @$ in %initial-action designate the
10692 Push them in the stacks.
10693 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
10695 2004-09-20 Akim Demaille <akim@epita.fr>
10697 * doc/bison.texinfo (Initial Action Decl): New.
10699 2004-09-20 Akim Demaille <akim@epita.fr>
10701 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
10702 clearer criterion to define it.
10703 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
10704 When reducing on an empty RHS, use the latest stacked location as
10706 yylloc is not always available.
10707 * data/glr.c: Likewise.
10708 Also, honor initial-actions.
10710 2004-09-20 Akim Demaille <akim@epita.fr>
10712 * data/yacc.c (YY_LOCATION_PRINT): New.
10713 Define when we know YYLTYPE's structure, i.e., when the default
10714 YYLLOC_DEFAULT is used.
10715 * data/c.m4 (b4_yysymprint_generate): Use it.
10716 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
10717 value of the result.
10718 (error_start_): Replace with...
10719 (error_range_): this location array.
10720 This allows to replace code relying on the implementation of
10721 locations by portable code.
10722 * data/yacc.c (yylerrsp): Replace with...
10723 (yyerror_range): this.
10724 Every time a token is popped, update yyerror_range[0], to have an
10725 accurate location for the error token.
10726 * data/glr.c (YY_LOCATION_PRINT): New.
10727 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
10728 deference a pointer.
10729 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
10730 report the location in %printers.
10732 * src/scan-skel.l: Instead of abort, report error messages to ease
10733 understanding skeleton scanning failures.
10735 2004-09-16 Akim Demaille <akim@epita.fr>
10737 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
10738 (iterator, const_iterator): these, to be more in the C++ spirit.
10739 Also, return reverse iterators so that when displaying the stack
10740 we display its bottom first.
10741 (Parser::stack_print_, Parser::reduce_print_): Match the messages
10743 We should probably use vector here though.
10745 2004-09-16 Akim Demaille <akim@epita.fr>
10747 Have more complete shift traces.
10749 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
10750 to report Shifts instead of ad hoc YYDPRINTF invocations,
10751 including for the error token.
10752 * data/lalr1.cc (symprint_): Output the location.
10753 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
10754 output the location within the %printer.
10755 Activate GLR tests, at least to make sure they compile properly.
10756 They still don't pass though.
10757 * tests/calc.at: Adjust expect verbose output, since now "Entering
10758 state..." is on a different line than the "Shifting" message.
10760 2004-09-08 Akim Demaille <akim@epita.fr>
10762 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
10763 Bison directive from the Bison file to the invocation of this
10764 macro, so that these directives are passed to
10765 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10766 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10767 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10768 the extra Bison directives instead of the whole series.
10769 Change the grammar so that there are recoverable errors, and
10770 unrecoverable errors. Now we can have the parser give up before
10771 consuming the whole input. As a result we now can observe that
10772 the lookahead is freed when needed.
10773 Change the parser source to parse argv[1] instead of a hard coded
10775 Simplify yylex, and give a value and location to EOF.
10776 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10777 passed directives already coded in the file.
10778 Add some tests to check the location of "error".
10779 For some tests, the C++ parser is correct, and not yacc.c.
10780 For other tests, they provide different, but unsatisfying, values,
10781 so keep the C++ value so that at least one parser is "correct"
10782 according to the test suite.
10783 (Actions after errors): Remove, this is subsumed by the
10784 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
10786 2004-09-06 Akim Demaille <akim@epita.fr>
10788 * data/lalr1.cc: Adjust the indentation of the labels.
10789 (Parser::pop): New.
10792 2004-09-06 Akim Demaille <akim@epita.fr>
10794 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
10795 argument, an informative message.
10796 Call YY_SYMBOL_PRINT.
10797 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
10798 * data/lalr1.cc (destruct_): Likewise.
10799 In addition, no longer depend on b4_yysymprint_generate and
10800 b4_yydestruct_generate to generate these functions, do it "by
10803 2004-09-03 Akim Demaille <akim@epita.fr>
10805 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
10806 invoked, yydestruct the lookahead.
10807 * tests/calc.at (Calculator $1): Update the expected lengths of
10808 traces: there is an added line for the discarded lookahead.
10809 * doc/bison.texinfo (Destructor Decl): Some rewording.
10810 Define "discarded" symbols.
10812 2004-09-02 Akim Demaille <akim@epita.fr>
10814 * data/lalr1.cc (translate_, destruct_): No reason to be static.
10816 2004-09-02 Akim Demaille <akim@epita.fr>
10818 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
10819 (YYDSYMPRINTF): Rename as...
10820 (YY_SYMBOL_PRINT): this.
10821 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
10823 Use it instead of direct symprint_ calls.
10824 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
10827 2004-09-02 Akim Demaille <akim@epita.fr>
10829 * data/lalr1.cc (b4_yysymprint_generate): New.
10830 (symprint_): New member function, defined when YYDEBUG.
10831 Use it consistently instead of token/nterm debugging output by
10833 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
10834 %printer calls to use cdebug_ when using lalr1.cc.

10843 * doc/bison.texinfo (Implementing Loops): Rename as...
10844 (Implementing Gotos/Loops): this.
10846 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
10848 Adjust to latest gnulib.
10849 * bootstrap (gnulib_modules): Add xalloc-die.
10850 Set LC_ALL=C so that file names sort consistently.
10851 Prefer the gnulib copies of gettext.m4, glibc21.m4,
10852 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
10853 uintmax_t.m4, ulonglong.m4.
10854 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
10855 po.m4 since we are now using _gl.m4 instead.
10857 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
10859 * src/scan-action.l: Remove. Scanning of semantic actions is
10860 handled in scan-gram.l.
10862 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
10864 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.

10879 Don't assume %union.
10880 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
10881 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
10882 UNION-FLAG. All callers changed.
10883 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.

10885 this lets us remove a cast.
10886 (Printers and Destructors): Add non-%union test cases.
10888 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10890 * doc/bison.texinfo: Minor editorial changes, mostly to the new
10891 GLR writeups. E.g., avoid frenchspacing and the future tense,
10892 change "lookahead" to "look-ahead", and change "wrt" to "with
10895 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10897 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):

10958 C++ compiler. (trivial change)
10960 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
10962 Spent a few hours checking out which prerequisite versions the
10963 current sources actually require. I went all the way back to
10964 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
10965 a seemingly endless set of combinations of versions more recent
10966 than that. The bottom line is that the current sources require
10967 fairly recent versions of the build tools, and it'll be some work
10969 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
10970 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
10971 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
10972 Add comments explaining why those particular versions are

10976 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
10977 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
10979 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
10980 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
10982 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
10984 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
10985 0.11.5. Suggested by Bruno Haible.
10986 * bootstrap: Remove gettext version checking.
10988 * doc/bison.texinfo (Decl Summary): Also mention that %union
10989 can depend on prerequisite types. Problem reported by Tim
10992 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
10994 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
10995 * README-alpha: Don't tell people not to package this.
10997 * bootstrap: Don't assume $(...) works; use `...` instead.
10998 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
11001 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
11002 put into the -d output file, and mention what to do if YYSTYPE is
11003 defined as a macro.
11005 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
11007 Undo change made earlier today: it caused autopoint to not bring
11008 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
11011 * bootstrap: Check that gettext version matches what's in
11012 configure.ac. Warn users to ignore robots.txt ERROR 404.
11013 * bootstrap: Undo today's earlier change (logged below).
11014 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
11016 The gettext version checking is causing more trouble than it's
11017 curing; remove it. Problem reported by Paul Hilfinger.
11019 * bootstrap: Issue a warning that one can expect a message
11020 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
11021 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
11023 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
11025 Ensure that the C++ compiler used for testing actually works on a
11026 simple test program; if not, skip the C++-related tests. Problem
11027 reported by Vin Shelton in:
11028 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html

11035 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
11037 * data/glr.c (yylloc): Output this macro even if locations are not
11038 being generated, as the GLR parser needs it even in that case.
11039 Problem reported by Troy A. Johnson
11040 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
11042 * configure.ac (AC_INIT): Update to 1.875e.

11046 * NEWS: Version 1.875d.
11047 * configure.ac (AC_INIT): Likewise.
11048 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
11050 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
11051 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
11052 lalr1.cc runs afoul of the first, and the last two are no longer
11053 supported by GCC 3.4.0.
11054 * README: Mention GNU m4 1.4 or later; mention m4 patches.
11055 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
11057 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
11059 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
11060 unsigned int, for compatibility with latest gnulib hash module.
11061 * src/state.c (state_hash, state_hasher): Likewise.
11062 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.
11063 * src/uniqstr.c (hash_uniqstr): Likewise.
11065 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>

11069 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
11070 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
11071 character and string literals.
11072 (unexpected_end): New function.
11073 (unexpected_eof): Use it.
11074 (unexpected_newline): New function.
11075 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
11078 * NEWS: Document %expect-rr.
11080 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
11081 Fix typo by replacing $1 with $option.
11082 Remove more 'intl'-related files.
11083 Don't DEFUN AM_INTL_SUBDIR twice.
11085 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
11086 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,

11092 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
11093 * src/.cvsignore: Add *.output.
11095 * src/parse-gram.y: Put copyright notice inside %{ %} so it
11096 gets copied to the output file.
11098 2004-04-28 Paul Eggert <eggert@twinsun.com>
11100 Get files from the gnulib and po repositories, instead of relying
11101 on them being in our CVS. Upgrade to latest versions of gnulib
11104 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
11105 * bootstrap: Bootstrap from gnulib and po repositories.
11106 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
11107 * README-cvs: Document these changes. Remove version numbers from
11108 mentions of build tools, since they change so often. Mention Flex.
11110 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
11111 (gl_USE_SYSTEM_EXTENSIONS): Add.
11112 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
11113 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
11115 (AC_ISC_POSIX): Remove; we no longer support this
11116 ancient OS, as it gets in the way of latest Autoconf & gnulib.
11117 (AC_HEADER_STDC): Remove: we now assume C89 or better.
11118 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
11119 Do not check for C89 headers, except for locale.h which is used
11120 by the Yacc library and must port to K&R hosts.
11121 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
11122 Do not check for C89 functions, except for setlocale which is
11123 used by the Yacc library.
11124 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
11125 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

11128 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
11129 AM_GNU_GETTEXT): Remove; now done by:
11130 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
11131 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
11134 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
11135 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
11136 Define to empty, as gnulib.mk will do the rest for us.
11137 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
11139 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
11140 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
11142 * src/files.c: Include gnulib's xstrndup.h.
11144 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
11145 (REALLOC): Use xnrealloc, for likewise.
11146 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
11147 (strnlen, memrchr): Remove decls; functions no longer used.
11148 Include <stpcpy.h>.
11150 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

11170 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
11171 Remove, as these files are now generated automatically
11172 by bootstrap or automake.
11174 * po/ChangeLog: Remove: all but one entry was a duplicate
11175 of this file, and I moved that 2000-11-02 entry here.
11177 * config/.cvsignore: Add Makefile, depcomp, install-sh.
11178 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

11193 * po/.cvsignore: Add *.po, LINGUAS, Makefile.in.in, Makevars.
11194 * src/.cvsignore: Remove *_.c.
11197 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
11198 support it. (The latest stable gzip doesn't.)
11200 2004-04-27 Paul Eggert <eggert@twinsun.com>
11202 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
11203 case, as stos_ is now used by destructors due to the 2004-02-09
11206 Remove more K&R C support.
11207 * lib/libiberty.y (PARAMS): Remove. All uses removed.
11208 * lib/subpipe.c (errno): Remove decl.
11209 Include <stdlib.h> unconditionally.
11210 (EXIT_FAILURE): Remove macro.
11211 * src/complain.c (vfprintf, strerror): Remove.
11212 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
11214 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
11215 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
11216 (strchr, strspn, memchr): Remove decls.
11217 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
11218 unconditionally. Do not declare perror.
11219 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
11222 * src/complain.c (_): Remove useless defn, as system.h defines this.
11224 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
11225 with latest obstack.h.
11226 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
11227 to procedure types, as obstack.h now does that for us.
11228 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
11230 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
11231 so that this include file can stand alone.
11232 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h

11234 test whether it can stand alone.
11236 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
11237 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
11238 unused declaration.
11240 * tests/synclines.at (%union synch line): Put a dummy member in
11241 the union, because empty unions aren't allowed in C. Caught

11308 Warn if expected_rr_conflicts used in non-GLR parser.
11310 * doc/bison.texinfo: Add documentation for %expect-rr.
11312 2004-03-08 Paul Eggert <eggert@gnu.org>
11314 Add support for hex token numbers. Suggested by Odd Arild Olsen in

11324 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
11325 Say "long int", not "long", for uniformity with GNU style.
11327 2004-02-25 Paul Eggert <eggert@twinsun.com>
11329 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
11330 compilers. This fixes a problem with Intel's C++ compiler being
11331 chatty, reported by Guido Trentalancia in
11332 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
11334 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>

11350 it can be called with `%skeleton "lalr1.cc"', and do that.
11352 2004-02-02 Paul Eggert <eggert@twinsun.com>
11354 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
11355 $(top_srcdir)/lib and ../lib. This fixes a bug reported
11356 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
11357 There's no need to mention top_builddir since Automake does that
11359 (INCLUDES): Remove, as Automake says it's obsolescent.
11360 Contents migrated into AM_CPPFLAGS as described above.
11361 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
11363 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>

11369 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11371 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that

11377 * src/output.c (output_skeleton): Rename local var.
11378 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
11379 Bison tokens, as this runs afoul of the 2003-10-07 change that
11380 disallowed NUL bytes in character constants or string literals.
11382 * tests/local.at: Require Autoconf 2.59's Autotest.
11383 * tests/testsuite.at: Don't include local.at, since we now assume
11384 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
11386 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
11387 multiple inclusion warnings.

11407 Complain about NUL bytes in character constants or string literals.
11409 2003-10-05 Paul Eggert <eggert@twinsun.com>
11411 * NEWS: Don't document %no-default-prec, as it's still
11413 * doc/bison.texinfo: Document %no-default-prec only if
11414 the defaultprec flag is set. Normally it's not.
11416 2003-10-04 Paul Eggert <eggert@twinsun.com>
11418 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
11419 non-modifiable lvalue, instead of a modifiable one.
11420 * doc/bison.texinfo (Actions): Document that $$ can
11421 be assigned to. Do not claim that $$ and $N are
11422 array element references: user code should not rely on this.

11460 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify

11472 Adjust: nerrs and errstatus is now replaced by...
11473 (Parser::nerrs_, Parser::errstatus_): New.
11475 2003-08-25 Akim Demaille <akim@epita.fr>
11477 * config/announce-gen, Makefile.cfg: New.

11480 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
11482 2003-08-25 Akim Demaille <akim@epita.fr>
11484 When reducing initial empty rules, Bison parser read an initial
11485 location that is not defined. This results in garbage, and that
11486 affects Bison's own parser. Therefore we need (i) to extend Bison
11487 to support a means to initialize this location, and (ii) to use
11488 this CVS Bison to fix CVS Bison's parser.
11490 * src/reader.h, reader.c (epilogue_augment): Remove, replace
11492 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.

11495 (%error-verbose): Since we require CVS Bison, there is no reason
11497 * src/scan-gram.l: Adjust.
11498 * src/Makefile.am (YACC): New, to make sure we use our own parser.
11499 * data/yacc.c (yyparse): Use b4_initial_action.
11501 2003-08-25 Akim Demaille <akim@epita.fr>
11503 * doc/bison.texinfo: Don't promote stdout for error messages.
11505 2003-08-25 Akim Demaille <akim@epita.fr>
11507 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.

11526 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
11527 error recovery loops. This patch is based on
11528 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
11529 Also, augment the similarity between lalr1.cc and yacc.c.
11530 Note: the locations of error recovery rules are not correct yet.
11532 * data/lalr1.cc: Comment changes to augment the similarity between
11533 lalr1.cc and yacc.c.
11534 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
11535 (yyerrlab1): Remove, but where it used to be (now the bottom part of
11536 yyerrlab), when hitting EOF, pop the whole stack here instead of
11537 merely falling thru the default error handling mechanism.
11538 (yyerrorlab): New label, with the old contents of YYERROR,
11539 plus the following change: pop the stack of rhs corresponding
11540 to the production that invoked YYERROR. That is how Yacc
11541 behaves (required by POSIX).
11542 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
11545 2003-08-25 Akim Demaille <akim@epita.fr>
11547 Tune local.at so that people can "autom4te -l autotest calc.at -o
11548 calc" for instance, to extract a sub test suite.
11550 * tests/testsuite.at: Move the initialization, Autotest version
11551 requirement, and AT_TESTED invocation into...

11560 Rework code slightly to avoid gcc -Wtraditional warnings.
11561 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
11562 The returned value is now stored in *YY0. All callers changed.
11563 * src/output.c (merge_output): Adjust to the above change.
11565 2003-07-26 Paul Eggert <eggert@twinsun.com>
11567 * data/glr.c (YYASSERT): New macro.
11568 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
11569 yyresolveStates, yyprocessOneStack):
11570 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
11571 Derived from a suggestion by Frank Heckenbach.
11573 2003-07-25 Paul Eggert <eggert@twinsun.com>
11575 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
11576 for portability to K&R C (after ansi2knr, presumably). See
11577 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
11578 by Frank Heckenbach, though I have omitted the structure-initialization
11579 part of his glr-knr.diff patch since I recall that the Portable
11580 C Compiler didn't require that change.
11582 Let the user specify how to allocate and free memory.
11583 Derived from a suggestion by Frank Heckenbach in
11584 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
11585 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
11586 All uses of free, malloc, realloc changed to use these macros,
11587 and unnecessary casts removed.
11588 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
11590 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
11592 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
11593 use s.empty() rather than s == "" to test for empty string; see
11594 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>

11613 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
11614 yyreportTree): Do not assume that size_t is the same width as int,
11615 when printing sizes. Print sizes using an unsigned format.
11616 Problem reported by Frank Heckenbach in
11617 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
11619 Port to Forte Developer 7 C compiler.

11624 the Forte Developer 7 C compiler complains that end-of-loop
11625 code is not reached.

11689 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
11690 (MOSTLYCLEANFILES): New var.
11691 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
11692 (stdbool.h): New rule.
11693 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
11694 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
11695 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
11696 m4/quote.m4: Upgrade to today's gnulib.
11698 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
11699 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
11700 the tests right now.
11701 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
11702 yyerror are declared before use; C99 requires this.
11704 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11706 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
11708 (yyrecoverSyntaxError): Correct the logic for setting and testing
11710 Correct comment on handling EOF.
11711 Allow states with only a default reduction, rather than failing
11712 (I can't quite reconstruct why these were not allowed before).
11714 Fixes to avoid problem that $-N rules in GLR parsers can cause
11715 buffer overruns, corrupting state.
11717 * src/output.c (prepare_rules): Output max_left_semantic_context
11719 * src/reader.h (max_left_semantic_context): New variable declaration.
11720 * src/scan-gram.l (max_left_semantic_context): Define.
11721 (handle_action_dollar): Update max_left_semantic_context.
11722 * data/glr.c (YYMAXLEFT): New definition.
11723 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
11724 (yyresolveAction): Ditto.
11726 Fixes to problems with location handling in GLR parsers reported by
11727 Frank Heckenbach (2003/06/05).
11729 * data/glr.c (YYLTYPE): Make trivial if locations not used.
11730 (YYRHSLOC): Add parentheses, and define only if locations used.
11731 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
11732 locations not used.
11733 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
11734 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
11736 * tests/cxx-type.at: Exercise location information; update tests
11737 to differentiate output with and without locations.
11738 Remove forward declarations of yylex and yyerror---caused errors
11739 because default YYLTYPE not yet defined.
11740 Change semantic actions to compute strings, rather than printing
11741 them directly (to test proper passing of semantics values). Change
11742 output to prefix notation and update test data and expected results.
11743 (yylex): Track locations.
11744 (stmtMerge): Return value rather than printing, and include arguments
11747 2003-06-03 Paul Eggert <eggert@twinsun.com>
11749 Avoid warnings generated by GCC 2.95.4 when Bison is
11750 configured with --enable-gcc-warnings.
11751 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
11752 yy::]b4_parser_class_name[::translate_,
11753 yy::Stack::operator[] (unsigned),
11754 yy::Stack::operator[] (unsigned) const,
11755 yy::Slice::operator[] (unsigned),
11756 yy::Slice::operator[] (unsigned) const):
11757 Rename local vars to avoid warnings.
11758 * tests/glr-regression.at (Improper handling of embedded actions
11759 and $-N in GLR parsers): Remove unused local variable from yylex.
11760 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
11761 (void) as arg when not pure, since we now assume C89 when building
11762 Bison. Pacify GCC by using parameter.
11764 2003-06-02 Paul Eggert <eggert@twinsun.com>
11766 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
11767 yy::Location::lines, yy::Location::columns): Rename arguments
11768 to avoid shadowing; this removes a warning generated by GCC 3.3.
11770 2003-06-01 Paul Eggert <eggert@twinsun.com>
11772 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
11773 to g++, as GCC 3.3 complains if you do it.
11774 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
11775 everything that WARNING_CFLAGS has, except omit warnings
11776 not suitable for C++.
11777 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
11778 * tests/atlocal.in (CXXFLAGS): New var.
11779 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
11781 Fix a GLR parser bug I reported in February; see
11782 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
11783 The problem was that GLR parsers did not conform to the C standard,
11784 because actions like { $1 = $2 + $3; } expanded to expressions
11785 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11786 to a local variable. The C standard says that expressions
11787 like (var = f ()) + (var = f ()) have undefined behavior.
11788 Another problem was that GCC sometimes issues warnings that
11789 yyfill and its parameters are unused.
11791 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11792 as possibly unused.
11793 (yyfill): New function.
11795 (yyuserAction): Change type of yynormal to bool, so that it matches
11796 the new yyfill signature. Mark it as possibly unused.
11799 Follow up on a bug I reported in February, where a Bison-generated
11800 parser can loop. Provide a test case and a fix for yacc.c. I
11801 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11802 The original bug report is in:
11803 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
11805 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11806 macro's size was becoming unwieldy.
11807 (yyerrlab): Do not discard an empty lookahead symbol, as this
11808 might destroy garbage.
11809 (yyerrorlab): New label, with the old contents of YYERROR,
11810 plus the following change: pop the stack of rhs corresponding
11811 to the production that invoked YYERROR. That is how Yacc
11812 behaves, and POSIX requires this behavior.
11813 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11814 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11815 Define 'alarm' to do nothing if unistd.h is not available.
11816 Add a new rule "exp: '-' error;" to test the above change to
11817 data/yacc.c. Use 'alarm' to abort any test taking longer than
11818 10 seconds, as it's probably looping.
11819 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11820 Also, the new yacc.c generates two fewer diagnostics for an
11823 2003-05-24 Paul Eggert <eggert@twinsun.com>
11825 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
11826 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
11827 This fixes a problem reported by John Bowman when the Compaq/HP
11828 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
11829 -ansi -Wall -gall).
11830 * data/yacc.c (union yyalloc): Likewise.
11831 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
11833 Switch from 'int' to 'bool' where that makes sense.
11835 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
11836 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
11837 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
11838 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
11839 Return or accept bool, not int. All callers changed.
11840 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
11841 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.

11850 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
11851 bitset_stats_or_and_cmp): Likewise.
11852 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,

11858 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
11859 lbitset_xor_cmp): Likewise.
11860 * lib/bbitset.h: Include <stdbool.h>.
11861 (struct bitset_vtable): The following members now return bool, not
11862 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
11863 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
11865 * src/conflicts.c (count_rr_conflicts): Likewise.
11866 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
11868 * lib/ebitset.c (ebitset_obstack_init): Likewise.
11869 * lib/lbitset.c (lbitset_obstack_init): Likewise.
11870 * src/getargs.c (debug_flag, defines_flag, locations_flag,

11872 graph_flag): Likewise.
11873 * src/getargs.h (debug_flag, defines_flag, locations_flag,

11875 graph_flag): Likewise.
11876 * src/output.c (error_verbose): Likewise.

11878 * src/reader.c (start_flag, typed): Likewise.

11881 (long_options, getargs): Use it.
11882 * src/lalr.c (build_relations): Use bool, not int.
11883 * src/nullable.c (nullable_compute): Likewise.
11884 * src/print.c (print_reductions): Likewise.
11885 * src/tables.c (action_row, pack_vector): Likewise.
11886 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
11887 * src/output.c (prepare): Use it.
11888 * src/output.c (token_definitions_output,
11889 symbol_destructors_output, symbol_destructors_output): Use string,
11890 not boolean integer, to keep track of whether to output separator.
11891 * src/print_graph.c (print_core): Likewise.
11892 * src/state.c (state_rule_lookaheads_print): Likewise.
11894 * config/install-sh: Sync from automake 1.7.5.
11896 2003-05-14 Paul Eggert <eggert@twinsun.com>
11898 * src/parse-gram.y (rules_or_grammar_declaration): Require a
11899 semicolon after a grammar declaration, in the interest of possible
11900 future changes to the Bison input language.
11901 Do not allow a stray semicolon at the start of the grammar.
11902 (rhses.1): Allow one or more semicolons after any rule, including
11903 just before "|" as required by POSIX.
11904 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
11907 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11909 %parse-param support for lalr1.cc.
11911 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
11912 b4_cc_constructor_calls, b4_cc_constructor_call,
11913 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
11915 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
11916 parse-param arguments.
11917 (yy::b4_parser_class_name): Declare instance variables to
11918 hold parse-param arguments.
11919 * tests/calc.at: s/value/semantic_value/ because value clashes
11920 with a member of yy::b4_parser_class_name. Adjust C++ code
11921 to handle %parse-param. Enable %parse-param test in C++.
11923 2003-05-12 Paul Eggert <eggert@twinsun.com>
11925 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
11926 English a bit. Fix fclose typo. Change "const char" to "char
11927 const", and use ANSI C rather than K&R for "main". Suggest
11928 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
11929 and suggest yy_switch_to_buffer.
11931 2003-05-05 Paul Eggert <eggert@twinsun.com>
11933 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
11934 C89. This avoids a diagnostic on compilers that define __STDC__
11935 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
11936 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11938 2003-05-03 Paul Eggert <eggert@twinsun.com>
11940 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
11941 Do not overrun array bounds.
11942 This should fix a bug reported today by Olatunji Oluwabukunmi in
11943 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
11945 2003-04-29 Akim Demaille <akim@epita.fr>
11947 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
11948 * src/getargs.c, src/getargs.h: here, as bool, not int.
11949 (nondeterministic_parser): New.
11950 * src/parse-gram.y, src/scan-gram.l: Support
11951 %nondeterministic-parser.
11952 * src/output.c (prepare): Use nondeterministic_parser instead
11953 of glr_parser where appropriate.
11954 * src/tables.c (conflict_row, action_row, save_row)
11955 (token_actions, token_actions, pack_vector): Ditto.
11957 2003-04-29 Akim Demaille <akim@epita.fr>
11959 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
11961 2003-04-29 Akim Demaille <akim@epita.fr>
11963 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
11964 with %pure-parser and %locations to exercise the patch from Yakov
11967 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
11969 * data/yacc.c: (b4_lex_param): Corrected for the case where
11970 %lex-param is provided and %pure-parser isn't.
11972 2003-04-27 Paul Eggert <eggert@twinsun.com>
11974 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
11975 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
11976 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
11977 if it is not defined.
11978 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
11980 2003-04-26 Paul Eggert <eggert@twinsun.com>
11982 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
11983 Declare to be of type suitable for the ninf value itself, not of
11984 type suitable for the corresponding table, since the latter might
11985 be unsigned but the ninf value might be negative. This fixes a
11986 bug reported by Alexandre Duret-Lutz in
11987 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
11989 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
11990 invokes it. We shouldn't invoke it twice because it will attempt
11991 to put error.o in the archive twice. This fixes a glitch reported
11992 by Martin Mokrejs in
11993 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11995 2003-04-21 Paul Eggert <eggert@twinsun.com>
11997 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
12000 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
12002 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
12003 Fix obvious typo that results in uncompilable GLR parsers
12004 when both %pure-parser and %locations are used. (trivial change)
12006 2003-04-17 Paul Eggert <eggert@twinsun.com>
12008 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
12009 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
12010 Do not insert the expected token via unput, as this runs afoul
12011 of a POSIX-compatibility bug in flex 2.5.31.
12012 All uses changed to BEGIN the parent state,
12013 since we no longer insert the expected token via unput.
12014 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
12015 that is no longer emitted after the above change.
12017 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
12018 the first one. This change is from Paul Hilfinger, and it fixes
12019 regression reported by Werner Lemberg in
12020 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
12022 (resolve_sr_conflict): Don't invoke state_errs_set
12023 unless one or more tokens have been explicitly made errors.
12024 Otherwise, the above change causes Bison to abort.
12026 * tests/existing.at (GNU pic Grammar): New test case, taken from
12029 2003-03-31 Akim Demaille <akim@epita.fr>
12031 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
12033 2003-03-31 Akim Demaille <akim@epita.fr>
12035 * src/output.c (prepare_symbols): Avoid trailing spaces in the
12038 2003-03-31 Akim Demaille <akim@epita.fr>
12040 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
12041 From Paul Hilfinger.
12043 2003-03-29 Akim Demaille <akim@epita.fr>
12045 * m4/error.m4: Do not put under dynamic conditions some code which
12046 expansion is under static control.
12048 2003-03-29 Akim Demaille <akim@epita.fr>
12050 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
12052 2003-03-29 Akim Demaille <akim@epita.fr>
12054 * doc/bison.texinfo (Strings are Destroyed): New.
12056 2003-03-13 Paul Eggert <eggert@twinsun.com>
12058 * .cvsignore: Add configure.lineno.
12059 * src/.cvsignore: Add yacc.
12060 * tests/.cvsignore: Add testsuite.log.
12061 * doc/fdl.texi: Sync with latest FSF version.
12063 2003-03-12 Paul Eggert <eggert@twinsun.com>
12065 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
12066 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
12067 cursor, instead of leaving it undefined. This fixes a bug
12068 reported by Tim Van Holder in
12069 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
12070 * tests/input.at (Torturing the Scanner): Test the scanner on
12071 an empty input file, which was Tim Van Holder's test case.
12073 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
12074 <sys/resource.h> can be included, include sys/time.h and
12075 sys/times.h first, if available. This works around the SunOS
12076 4.1.4 porting bug reported by Bruce Becker in
12077 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
12079 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
12080 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
12081 AC_HEADER_SYS_WAIT.
12083 Merge changes from gnulib. This was prompted because the CVS
12084 snapshot didn't build on Solaris 7 due to strnlen problems.
12086 These changes need to be merged back into gnulib:
12087 * lib/hash.c: Include <stdbool.h> unconditionally.
12088 * m4/onceonly.m4 (m4_quote): New macro.
12089 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
12090 Quote AC_FOREACH variable-expansions properly.
12091 The 2003-01-03 obstack.h change also needs merging.
12092 {end of changes requiring merging}
12094 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
12095 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,

12126 assuming at least C89 in the bitset code for some time now.
12128 2003-03-03 Akim Demaille <akim@epita.fr>
12132 2003-03-02 Akim Demaille <akim@epita.fr>
12134 * doc/bison.texinfo (Table of Symbols): Reactivate the
12135 documentation for %lex-param, and %parse-param.
12137 2003-03-02 Akim Demaille <akim@epita.fr>
12139 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
12140 generate verbose error messages.
12141 Use the number of tokens as an upper bound in yytname, as it
12142 cannot be a non terminal.
12144 2003-03-02 Akim Demaille <akim@epita.fr>
12146 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
12149 2003-03-02 Akim Demaille <akim@epita.fr>
12151 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
12152 Use them to exercise yycheck overrun.
12153 Based on Andrew Suffield's grammar.
12155 2003-03-02 Akim Demaille <akim@epita.fr>
12157 Create tests/local.at for Bison generic testing macros.
12159 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
12160 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):

12163 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
12164 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
12165 * tests/local.at: here.
12166 (AT_COMPILE_CXX): Tags the tests using it as c++.
12167 Ignore the test if CXX is not functional.
12169 2003-03-01 Paul Eggert <eggert@twinsun.com>
12171 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
12172 not loc->end, since loc->end might contain garbage and this leads
12173 to undefined behavior on some platforms.
12174 (id_loc, token_start): Use (IF_LINTed) initial values that do not
12175 depend on *loc, so that the reader doesn't give the the false
12176 impression that *loc is initialized.
12177 (<INITIAL>"%%"): Do not bother setting code_start, since its value
12178 does not survive the return.
12180 2003-03-01 Akim Demaille <akim@epita.fr>
12182 * src/scan-gram.l (code_start): Always initialize it when entering
12183 into yylex, as SC_EPILOGUE is activated *before* the corresponding
12184 yylex invocation. An alternative would be making it static, but
12185 then it starts with the second %%'s beginning, instead of its end.
12187 2003-02-28 Paul Eggert <eggert@twinsun.com>
12189 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
12190 around a UnixWare 7.1.1 porting bug reported by John Hughes in
12191 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
12193 2003-02-26 Paul Eggert <eggert@twinsun.com>
12195 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
12196 Remove Sequent/Pyramid discussion (nobody uses them any more).
12197 Merge VMS and MS-DOS discussion; these ports may well be dead
12198 but let's keep mentioning them for now. Put <> around email
12199 addresses. Add copyright notice.
12201 2003-02-24 Paul Eggert <eggert@twinsun.com>
12203 * data/glr.c (yy_reduce_print): yylineno -> yylno,
12204 to avoid collision with flex use of yylineno.
12205 Problem reported by Bruce Lilly in
12206 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

12215 change integer types.
12216 Suggested by Paul Eggert.
12218 2003-02-21 Akim Demaille <akim@epita.fr>
12220 * doc/bison.texinfo: Use "location" consistently to refer to @n,
12221 to avoid confusions with lalr1.cc's notion of Position.
12222 Suggested by Paul Eggert.
12224 2003-02-20 Akim Demaille <akim@epita.fr>
12226 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
12227 before initial_columns.
12228 (location.hh): Use consistent variable names when defining the
12230 Use "last" so that we subtract from Positions, not from unsigned.
12232 2003-02-20 Akim Demaille <akim@epita.fr>
12234 * data/lalr1.cc (position.hh): New subfile, including the extended
12235 and Doxygen'ed documentation of class Position.
12236 (location.hh): Use it.
12237 Document a` la Doxygen.
12238 With the help of Benoit Perrot.
12240 2003-02-20 Akim Demaille <akim@epita.fr>
12242 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
12244 Redefine AT_YYERROR_SEES_LOC_IF using it.
12245 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
12247 Don't use the location in yy::Parser::error_ and
12248 yy::Parser::print_ when not %locations.
12249 Activate more lalr1.cc tests.
12251 2003-02-19 Akim Demaille <akim@epita.fr>
12253 * data/lalr1.cc: When displaying a line number, be sure to make it
12256 2003-02-19 Akim Demaille <akim@epita.fr>
12258 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
12260 (YYABORT, YYACCEPT, YYERROR): New.
12261 * tests/calc.at: Renable the lalr1.cc test.
12263 2003-02-19 Akim Demaille <akim@epita.fr>
12265 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
12266 error recovery, mixing with/without pops and discarding of the
12269 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
12271 2003-02-17 Paul Eggert <eggert@twinsun.com>
12273 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
12274 * tests/testsuite.at (AT_COMPILE): Use them.
12275 This fixes the testsuite problem reported by Robert Lentz in
12276 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
12278 2003-02-12 Paul Eggert <eggert@twinsun.com>
12280 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
12281 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
12282 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
12283 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
12284 Check for malloc failure, for consistency with yacc.c.
12285 (yytname_size): Remove, for consistency with yacc.c.
12287 The bug still remains in data/lalr1.cc, as I didn't have time
12290 2003-02-06 Akim Demaille <akim@epita.fr>
12292 * configure.ac (GXX): Rename as...
12293 (CXX): this, to keep the original Autoconf semantics.
12295 * data/lalr1.cc: Fix b4_copyright invocations.
12296 If YYDEBUG is not defined, don't depend upon name_ being defined.
12297 (location.hh): Include string and iostream.
12298 (Position::filename): New member.
12299 (Position::Position ()): New.
12300 (operator<< (Position)): New.
12301 (operator- (Position, int)): New.
12302 (Location::first, Location::last): Rename as...
12303 (Location::begin, Location::end): these, to mock the conventional
12305 (operator<< (Location)): New.
12306 * tests/atlocal.in (CXX): New.
12307 * tests/testsuite.at (AT_COMPILE_CXX): New.
12308 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
12309 locations in a more synthetic way.
12310 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
12312 Adjust the C locations to match those from Emacs: first column is
12314 Change all the expected results.
12315 Conform to the GCS: simplify the locations when applicable.
12316 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
12317 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
12318 these CPP macros with the m4 macros new defined by...
12319 (AT_CHECK_PUSHDEFS): this, i.e.:
12320 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
12321 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
12323 (AT_CHECK_POPDEFS): Undefine them.
12324 (AT_CHECK_CALC_LALR1_CC): New.
12325 Use it for the first lalr1.cc test.
12327 2003-02-04 Akim Demaille <akim@epita.fr>
12329 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
12330 Location as is defined.
12332 2003-02-04 Akim Demaille <akim@epita.fr>
12334 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
12335 name_ being defined.
12337 2003-02-03 Paul Eggert <eggert@twinsun.com>
12339 * src/gram.h (start_symbol): Remove unused decl.
12341 Use more-consistent naming conventions for local vars.
12343 * src/derives.c (derives_compute): Change type of local var from
12344 int to rule_number.
12345 * src/gram.c (grammar_rules_partial_print): Likewise.
12346 * src/print.c (print_core): Likewise.
12347 * src/reduce.c (reduce_grammar_tables): Likewise.
12349 * src/gram.c (grammar_dump): Change name of item_number *
12350 local var from r to rp.
12351 * src/nullable.c (nullable_compute): Likewise.
12353 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
12355 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
12356 for symbol or symbol_number var.
12357 * src/reader.c (grammar_start_symbol_set): Likewise.
12358 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
12360 * src/state.c (transitions_to): Likewise.
12361 * src/state.h: Likewise.
12362 * src/tables.c (symbol_number_to_vector_number): Likewise.

12379 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
12381 * src/uniqstr.h: Likewise.
12383 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
12384 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
12385 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
12386 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
12387 param to have same name as that of enum, so that we don't use
12388 "s" to stand for a non-state.
12390 2003-02-02 Akim Demaille <akim@epita.fr>
12392 * src/scan-skel.l: Scan more than one inert character per yylex
12395 2003-02-01 Paul Eggert <eggert@twinsun.com>
12399 * po/LINGUAS: Add ms.
12401 2003-01-30 Akim Demaille <akim@epita.fr>
12403 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
12405 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12407 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
12410 Changes in response to error report by S. Eken: GLR mode does not
12411 handle negative $ indices or $ indices in embedded rules correctly.
12412 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
12414 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
12415 (b4_rhs_location): Ditto.
12416 (yyfill): New function to copy from stack tree into array
12418 (yyuserAction): Modify to allow incremental move of semantic values
12419 to rhs array when in GLR mode.
12420 Define YYFILL to use in user-defined actions to fill semantic array
12422 Remove dummy use of yystack, as there is now a guaranteed use.
12423 (yydoAction): Modify to allow incremental move of semantic values
12424 to rhs array when in GLR mode.
12425 (yyresolveAction): Ditto.
12426 (yyglrShiftDefer): Update comment.
12427 (yyresolveStates): Use X == NULL for pointers, not !X.
12428 (yyglrReduce): Ditto.
12429 (yydoAction): Ditto
12431 * tests/glr-regr1.at: Rename to ...
12432 * tests/glr-regression.at: Add new regression test for the problems
12433 described above (adapted from S. Eken).
12434 Update copyright notice.
12435 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
12436 * tests/Makefile.am: Ditto.
12438 2003-01-28 Paul Eggert <eggert@twinsun.com>
12440 * data/lalr1.cc: Do not use @output_header_name@ unless
12441 b4_defines_flag is set. This fixes two bugs reported by
12443 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
12444 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
12446 2003-01-21 Paul Eggert <eggert@twinsun.com>
12448 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
12449 we don't need to worry about yyerrlab1 being reported as an
12450 "unused label" by non-GCC C compilers. The downside is that if
12451 locations are used then a couple of statements are duplicated each
12452 time YYERROR is invoked, but the upside is that the warnings
12454 (yyerrlab1): Move code to YERROR.
12455 (yyerrlab2): Remove. Change uses back to yyerrlab1.
12456 This reverts some of the 2002-12-27 change.
12458 2003-01-17 Paul Eggert <eggert@twinsun.com>
12460 * src/output.c (symbol_printers_output): Fix typo that led
12461 to core dump. Problem reported by Antonio Rus in
12462 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
12464 2003-01-13 Akim Demaille <akim@epita.fr>,
12465 Quoc Peyrot <chojin@lrde.epita.fr>,
12466 Robert Anisko <anisko_r@lrde.epita.fr>
12468 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
12469 when the stacks contain one element, as the loop would otherwise
12470 free the last state, and then use the top state (the one we just
12471 popped). This means that the initial elements will not be freed
12472 explicitly, as is the case in yacc.c; it is not a problem, as
12473 these elements have fake values.
12475 2003-01-11 Paul Eggert <eggert@twinsun.com>
12477 * NEWS: %expect-violations are now just warnings, reverting
12478 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
12479 bootstrapping problem reported by Matthias Klose; see
12480 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
12481 * src/conflicts.c (conflicts_print): Likewise.
12482 * tests/conflicts.at (%expect not enough, %expect too much,
12483 %expect with reduce conflicts): Likewise.
12484 * doc/bison.texinfo (Expect Decl): Document this. Also mention
12485 that the warning is enabled if the number of conflicts changes
12486 (not necessarily increases).
12488 * src/getargs.c (version): Update copyright year.
12490 2003-01-09 Akim Demaille <akim@epita.fr>
12492 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
12494 2003-01-08 Paul Eggert <eggert@twinsun.com>
12496 * Makefile.maint (WGETFLAGS):
12497 New macro, containing "-C off" to disable proxy caches.
12498 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
12499 (rel-check): Use $(WGET) instead of wget.
12501 2003-01-06 Paul Eggert <eggert@twinsun.com>
12503 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
12504 the GLR paper of Scott, Johnstone and Hussain.
12506 2003-01-04 Paul Eggert <eggert@twinsun.com>
12508 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
12509 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
12510 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
12511 (EXTRA_LIBRARIES): New var, for liby.a.
12512 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
12513 (EXTRA_SCRIPTS): New var, for yacc.
12515 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
12516 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
12517 Problem reported by Nelson H. F. Beebe.
12519 2003-01-03 Paul Eggert <eggert@twinsun.com>
12521 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
12522 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
12523 when compiling Bison 1.875's `bitset bset = obstack_alloc
12524 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
12526 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
12527 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
12528 grow to a huge size with typical invocation.
12530 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
12531 Use the pattern recommended by Autoconf 2.57, except also protect
12532 against double-definition.
12533 * src/system.h: Likewise.
12534 Portability issues reported by Nelson H. F. Beebe.
12536 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
12537 All uses changed. Provide a definition in both C and C++.
12538 (yytrue, yyfalse): Define even if defined (__cplusplus).
12540 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
12541 Reported by Nelson H. F. Beebe.
12543 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
12545 2003-01-02 Paul Eggert <eggert@twinsun.com>
12547 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
12548 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
12549 Bug reported by Nelson H. F. Beebe.
12551 2003-01-01 Paul Eggert <eggert@twinsun.com>
12555 2002-12-30 Paul Eggert <eggert@twinsun.com>
12557 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
12559 (<INITIAL>","): Here. This causes stray "," to be treated
12562 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
12563 last brace in braced code when not in Yacc mode, for compatibility
12564 with Bison 1.35. This resurrects the 2001-12-15 patch to
12567 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
12568 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
12570 2002-12-28 Paul Eggert <eggert@twinsun.com>
12572 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
12573 that of SYM's type. This fixes Debian bug 168069, reported by
12576 2002-12-28 Paul Eggert <eggert@twinsun.com>
12580 Switch back to the Yacc style of conflict reports, undoing some
12581 of the 2002-07-30 change.
12582 * doc/bison.texinfo (Understanding): Use Yacc style for
12583 conflict reports. Also, use new way of locating rules.
12584 * src/conflicts.c (conflict_report):
12585 Renamed from conflict_report_yacc, removing the old
12586 'conflict_report'. Translate the entire conflict report at once,
12587 so that we don't assume that "," has the same interpretation in
12589 (conflicts_output): Use Yacc-style conflict report for each state,
12590 instead of our more-complicated style.
12591 (conflicts_print): Use Yacc-style conflict report, except print
12592 the input file name when not emulating Yacc.
12593 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
12594 Conflicted Reduction, %expect not enough, %expect too much,
12595 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
12596 * tests/existing.at (GNU Cim Grammar): Likewise.
12597 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
12599 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
12600 fatal): Don't invoke fflush; it's not needed and it might even be
12601 harmful for stdout, as stdout might not be open.
12602 * src/reduce.c (reduce_print): Likewise.
12604 2002-12-27 Paul Eggert <eggert@twinsun.com>
12606 Fix a bug where error locations were not being recorded correctly.
12607 This problem was originally reported by Paul Hilfinger in
12608 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
12610 * data/yacc.c (yyparse): New local var yylerrsp, to record the
12611 top of the location stack's error locations.
12612 (yyerrlab): Set it. When discarding a token, push its location
12613 onto yylerrsp so that we don't lose track of the error's end.
12614 (yyerrlab1): Now is only the target of YYERROR, so that we can
12615 properly record the location of the action that failed. For GCC
12616 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
12617 GCC warning about yyerrlab1 being unused if YYERROR is unused.
12618 (yyerrlab2): New label, which yyerrlab now falls through to.
12619 Compute the error's location by applying YYLLOC_DEFAULT to
12620 the locations of all the symbols that went into the error.
12621 * doc/bison.texinfo (Location Default Action): Mention that
12622 YYLLOC_DEFAULT is also invoked for syntax errors.
12623 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
12624 Error locations include the locations of all the tokens that were
12625 discarded, not just the last token.
12627 2002-12-26 Paul Eggert <eggert@twinsun.com>
12629 * src/files.c: Include quote.h.
12630 (compute_output_file_names): Warn if we detect conflicting
12631 outputs to the same file. This should catch the misunderstanding
12632 exemplified by Debian Bug 165349, reported by Bruce Stephens..
12634 * src/conflicts.c (conflicts_print): If the user specifies
12635 "%expect N", report an error if there are any reduce/reduce
12636 conflicts. This is what the manual says should happen.
12637 This fixes Debian bug 130890, reported by Anthony DeRobertis.
12638 * tests/conflicts.at (%expect with reduce conflicts): New test.
12640 Don't use m4_include on relative file names, as it doesn't work as
12641 desired if there happens to be a file with that name under ".".
12643 * m4sugar/version.m4: Remove; it was included but it wasn't used.
12644 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
12645 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
12646 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
12647 * src/output.c (output_skeleton): Use full path names when
12648 specifying a file to include; don't rely on include path, as
12649 it's unreliable when the working file contains a file with
12652 2002-12-25 Paul Eggert <eggert@twinsun.com>
12654 Remove obsolete references to bison.simple and bison.hairy.
12655 Problem mentioned by Aubin Mahe in
12656 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
12657 * data/glr.c: Comment fix.
12658 * doc/bison.1: Remove references. Also, mention "yacc".
12660 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
12663 * src/parse-gram.y (declaration): Use enum "report_states" rather
12664 than its numeric value 1.
12666 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
12667 opening a new one. This fixes Debian bug 165349, reported by
12670 2002-12-24 Paul Eggert <eggert@twinsun.com>
12674 * Makefile.maint (cvs-update): Don't assume that the shell
12675 supports $(...), as Solaris sh doesn't.
12677 * src/parse-gram.y (lloc_default): Remove test for empty
12678 nonterminals at the end, since it didn't change the result.
12680 2002-12-24 Paul Eggert <eggert@twinsun.com>
12682 If the user does not define YYSTYPE as a macro, Bison now declares it
12683 using typedef instead of defining it as a macro. POSIX requires this.
12684 For consistency, YYLTYPE is also declared instead of defined.
12686 %union directives can now have a tag before the `{', e.g., the
12687 directive `%union foo {...}' now generates the C code
12688 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12689 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12690 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12691 instead of `yyltype'.
12693 `yystype' and `yyltype' are now obsolescent macros instead of being
12694 typedefs or tags; they are no longer documented and will be
12695 withdrawn in a future release.
12697 * data/glr.c (b4_location_type): Remove.
12698 (YYSTYPE): Renamed from yystype.
12699 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
12700 (struct YYLTYPE): Renamed from struct yyltype.
12701 (YYLTYPE): Renamed from yyltype.
12702 (yyltype, yystype): New (and obsolescent) macros,
12703 for backward compatibility.
12704 * data/yacc.c: Likewise.
12706 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
12707 does not specify a union tag. This is for compatibility with
12710 * src/parse-gram.y (add_param): 2nd arg is now char * not char
12711 const *, since it is now modified by stripping surrounding { }.
12712 (current_braced_code): Remove.
12713 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
12714 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
12715 trailing " {...}". Now of type <chars>.
12716 (grammar_declaration): Adjust to bundled tokens.
12717 (code_content): Remove; stripping is now done by add_param.
12718 (print_token_value): Print contents of bundled tokens.
12719 (token_name): New function.
12721 * src/reader.h (braced_code, current_braced_code): Remove.
12722 (token_name): New decl.
12724 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
12725 token_type, not braced_code code_kind. All uses changed.
12726 (SC_PRE_CODE): New state, for scanning after a keyword that
12727 has (or usually has) an immediately-following braced code.
12728 (token_type): New local var, to keep track of which token type
12729 to return when scanning braced code.
12730 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
12731 <INITIAL>"%parse-param", <INITIAL>"%printer",
12732 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
12733 instead of returning a token type immediately.
12734 (<INITIAL>"{"): Set token type.
12735 (<SC_BRACED_CODE>"}"): Use it.
12736 (handle_action_dollar, handle_action_at): Now returns bool
12737 indicating success. Fail if ! current_rule; this prevents a core dump.
12738 (handle_symbol_code_dollar, handle_symbol_code_at):
12739 Remove; merge body into caller.
12740 (handle_dollar, handle_at): Complain in invalid contexts.
12742 * NEWS, doc/bison.texinfo: Document the above.
12743 * NEWS: Fix years and program names in copyright notice.
12745 2002-12-17 Paul Eggert <eggert@twinsun.com>
12747 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
12748 Reporting, Table of Symbols): Omit mentions of %lex-param and
12749 %parse-param from the documentation for now.
12751 2002-12-15 Paul Eggert <eggert@twinsun.com>
12753 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
12754 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
12755 lookahead symbol, and which sets yychar in parser actions) and it
12756 disagreed with the Bison documentation. Bug
12757 reported by Andrew Walrond.
12759 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
12760 as the caller now does that.
12761 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
12762 (YYEMPTY): Parenthesize right hand side, since others use it.
12763 (yyparse): Don't assume that our generated code is the only code
12766 2002-12-13 Paul Eggert <eggert@twinsun.com>
12770 POSIX requires a "yacc" command.
12771 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
12772 (MOSTLYCLEANFILES): Add yacc.
12774 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
12775 as an alias for bison y.
12777 * po/LINGUAS: Add da.
12779 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
12780 problem with latest <getopt.h>.
12781 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
12783 * doc/fdl.texi: Upgrade to 1.2.
12784 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
12785 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
12786 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
12788 * config/install-sh: Sync with autotools.
12790 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
12791 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12792 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
12793 locations are requested.
12794 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
12795 locations are requested.
12797 2002-12-12 Paul Eggert <eggert@twinsun.com>
12799 Remove unportable casts and storage allocation tricks.
12800 While we're at it, remove almost all casts, since they
12801 usually aren't needed and are a sign of trouble.
12803 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
12805 * src/derives.c (derives_compute): Do not subtract NTOKENS from
12806 the pointer DSET returned by malloc; this isn't portable.
12807 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
12808 Similarly for DERIVES.
12809 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
12810 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
12811 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
12813 * src/derives.c (derives_compute): Do not bother invoking
12814 int_of_rule_number, since rule numbers are integers.
12816 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
12817 rather than XMALLOC (char, N).
12819 * src/files.c (filename_split): Rewrite to avoid cast.
12821 * src/gram.h (symbol_number_as_item_number,
12822 item_number_as_symbol_number, rule_number_as_item_number,
12823 item_number_as_rule_number):
12824 Now inline functions rather than macros, to avoid casts.
12825 * src/state.h (state_number_as_int): Likewise.
12826 * src/tables.c (state_number_to_vector_number,
12827 symbol_number_to_vector_number): Likewise.
12829 * src/gram.h (int_of_rule_number): Remove; no longer used.
12831 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
12832 since the resulting storage is always stored into.
12834 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
12837 * src/muscle_tab.c (muscle_m4_output):
12838 Now inline. Return bool, not int.
12839 * src/state.c (state_compare): Likewise.
12840 * src/symtab.c (symbol_check_defined,
12841 symbol_check_alias_consistency, symbol_pack, symbol_translation,
12842 hash_compare_symbol, hash_symbol):
12844 * src/uniqstr.c (uniqstr_print): Likewise.
12845 * src/muscle_tab.c (muscle_m4_output_processor):
12846 New function, to avoid casts.

12848 * src/symtab.c (symbol_check_defined_processor,
12849 symbol_check_alias_consistency_processor, symbol_pack_processor,
12850 symbol_translation_processor, hash_symbol_comparator,
12851 hash_symbol_hasher): Likewise.
12852 * src/uniqstr.c (uniqstr_print_processor): Likewise.
12853 * src/muscle_tab.c (muscles_m4_output):
12854 Use new functions instead of casting old functions unportably.
12855 * src/state.c (state_hash_new): Likewise.
12856 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
12857 symbols_token_translations_init):
12859 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
12861 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
12862 var instead of casting to long, to avoid casts.
12863 (prepare_states): Use MALLOC rather than alloca, so that we don't
12864 have to worry about alloca.
12865 * src/state.c (state_hash_lookup): Likewise.
12867 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
12868 local var instead of casting to unsigned char, to avoid casts.
12870 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
12871 STATE_ALLOC): Remove.
12872 (transitions_new, errs_new, reductions_new, state_new): Use malloc
12873 rather than calloc, and use offsetof to avoid allocating slightly
12875 (state_new): Initialize all members.
12877 * src/state.c (state_hash): Use unsigned accumulator, not signed.
12879 * src/symtab.c (symbol_free): Remove; unused.
12880 (symbol_get): Remove cast in lhs of assignment.
12881 (symbols_do): Now static. Accept generic arguments, not
12882 hashing-related ones.
12884 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
12885 (symbol_processor): Remove.
12886 (symbols_do): Remove decl; now static.
12888 * src/system.h (alloca): Remove; decl no longer needed.
12889 (<stddef.h>): Include, for offsetof.
12890 (<inttypes.>, <stdint.h>): Include if available.
12891 (uintptr_t): New type, if system lacks it.
12892 (CALLOC, MALLOC, REALLOC): New macros.
12893 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these

12900 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
12902 * src/vcg.h: Correct misspellings.
12904 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
12907 * src/getargs.c (getargs): Don't assume EOF == -1.
12909 2002-12-09 Paul Eggert <eggert@twinsun.com>
12911 Change identifier spellings to avoid collisions with names
12912 that are reserved by POSIX.
12914 Don't use names ending in _t, since POSIX reserves them.
12915 For consistency, remove _e and _s endings -- they're weren't
12916 needed to remove ambiguity. All uses changed.
12917 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
12918 turn was just renamed from struniq_t.
12919 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
12920 which in turn was just renamed from struniq_processor_t.
12921 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
12922 in turn was renamed from hash_compare_struniq_t.
12923 * src/LR0.c (struct state_list): Renamed from struct state_list_s.
12924 (state_list): Renamed from state_list_t.

12992 value_t_as_yystype -> value_as_yystype.
12994 Don't include <errno.h> in the mainstream code, since it
12995 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.

12997 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

13000 * src/output.c (output_skeleton): Likewise.
13001 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno
13003 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>\\x[0-9abcdefABCDEF]+):
13005 (handle_action_dollar, handle_action_at): Likewise.
13006 * src/system.h: Do not include <errno.h>.
13007 (TAB_EXT): Renamed from EXT_TAB.
13008 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
13010 Avoid str[a-z]*, since <string.h> reserves that name space.
13011 Change all instances of "struniq" in names to "uniqstr", and
13012 likewise for "STRUNIQ" and "UNIQSTR".
13013 * src/uniqstr.c: Renamed from src/struniq.c.
13014 * src/uniqstr.h: Renamed from src/struniq.h.
13015 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.
13016 * src/files.c (strsuffix): Remove; unused.
13017 (concat2): Renamed from stringappend. Now static.
13018 * src/files.h (strsuffix, stringappend): Remove; unused.
13019 * src/parse-gram.y (<chars>): Renamed from <string>.
13020 (<uniqstr>): Renamed from <struniq>.
13021 * src/scan-gram.l (obstack_for_string): Renamed from string_obstack.
13022 * src/vcg.h (struct node_s.expand): Renamed from struct node_s.stretch.
13023 (struct graph_s.expand): Renamed from struct graph_s.stretch.
13024 * src/vcg_defaults.h (G_EXPAND): Renamed from G_STRETCH.
13025 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
13026 (N_EXPAND): Renamed from N_STRETCH.
13028 Avoid *_MAX and *_MIN, since <limits.h> reserves that name space.
13029 * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
13030 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):
13032 * src/lalr.h (GOTO_NUMBER_MAXIMUM): Renamed from GOTO_NUMBER_MAX.
13033 * src/state.h (STATE_NUMBER_MAXIMUM): Renamed from STATE_NUMBER_MAX.
13034 * src/symtab.h (SYMBOL_NUMBER_MAXIMUM): Renamed from SYMBOL_NUMBER_MAX.
13035 * src/tables.c (VECTOR_NUMBER_MAX, VECTOR_NUMBER_MIN): Remove; unused.
13036 (BASE_MAXIMUM): Renamed from BASE_MAX.
13037 (BASE_MINIMUM): Renamed from BASE_MIN.
13038 (ACTION_MAX): Remove; unused.
13039 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
13040 Unnecessary casts removed from above defines.
13043 Fix misspelling in names.
13044 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
13045 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
13049 * lib/timevar.c (timevar_report): Renamed from time_report,
13050 for consistency with other names.
13051 * lib/timevar.h (timevar_report): New decl.
13052 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
13055 Sort include-file uses.
13057 Reorder all include files under src to be in the order "system.h".
13058 then the ../lib include files in angle brackets (alphabetized),
13059 then the . include files in double-quotes (alphabetized). Fix
13060 dependency breakages encountered in this process, as follows:
13061 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
13062 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
13063 * src/state.h: Include "symtab.h".
13065 2002-12-08 Paul Eggert <eggert@twinsun.com>
13067 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
13068 since this causes problems when __file__ contains character
13069 sequences like "@" that are treated specially by src/scan-skel.l.
13070 Instead, just use the file's basename. This fixes the bug
13071 reported by Martin Mokrejs in
13072 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
13074 2002-12-06 Paul Eggert <eggert@twinsun.com>
13076 Add support for rules that do not have trailing semicolons, as
13077 POSIX requires. Improve the quality of locations in Bison
13080 * src/location.c: Include <quotearg.h>.
13081 (empty_location): Now const.
13082 (location_print): New function. Follow the recommendation of the
13083 GNU Coding Standards for locations that span file boundaries.
13084 * src/location.h: Do not include <quotearg.h>; no longer needed.
13085 (boundary): New type.
13086 (location_t): Use it. This allows locations to span file boundaries.
13087 All member uses changed: file -> start.file or end.file (as needed),
13088 first_line -> start.line, first_column -> start.column,
13089 last_line -> end.line, last_column -> end.column.
13090 (equal_boundaries): New function.
13091 (LOCATION_RESET, LOCATION_STEP): Remove.
13092 (LOCATION_PRINT): Remove. All callers changed to use location_print.
13093 (empty_location): Now const.
13094 (location_print): New decl.
13095 * src/parse-gram.y (lloc_default): New function, which handles
13096 empty locations more accurately.
13097 (YYLLOC_DEFAULT): Use it.
13098 (%token COLON): Remove.
13099 (%token ID_COLON): New token.
13101 (declarations, rules): Remove trailing semicolon.
13102 (declaration, rules_or_grammar_declaration):
13103 Allow empty (";") declaration.
13104 (symbol_def): Remove empty actions; no longer needed.
13105 (rules_or_grammar_declaration): Remove trailing semicolon.
13106 (semi_colon.opt): Remove.
13107 * src/reader.h: Include location.h.
13108 (scanner_cursor): New decl.
13109 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
13111 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
13113 (STEP): Remove. No longer needed, now that adjust_location does
13114 the work. All uses removed.
13115 (scanner_cursor): New var.
13116 (adjust_location): Renamed from extend_location. It now sets
13117 *loc and adjusts the scanner cursor. All uses changed.
13118 Don't bother testing for CR.
13119 (handle_syncline): Remove location arg; now updates scanner cursor.
13120 All callers changed.
13121 (unexpected_end_of_file): Now accepts start boundary of token or
13122 comment, not location. All callers changed. Update scanner cursor,
13124 (SC_AFTER_IDENTIFIER): New state.
13125 (context_state): Renamed from c_context. All uses changed.
13126 (id_loc, code_start, token_start): New local vars.
13127 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
13128 processing of Yacc white space and equivalents here.
13129 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
13130 instead of returning ID immediately, since we need to search for
13131 a subsequent colon.
13132 (<INITIAL>"'", "\""): Save token_start.
13133 (<INITIAL>"%{", "{", "%%"): Save code_start.
13134 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
13135 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
13136 BEGIN context_state at end, not INITIAL.
13137 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
13138 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
13139 Return correct token start.
13140 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
13141 the start of a character, string or multiline comment is found.
13142 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
13143 Reduction): Adjust reported locations to match the more-precise
13144 results now expected.
13145 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
13146 * tests/reduce.at (Useless Rules, Reduced Automaton,
13147 Underivable Rules): Likewise.
13148 * tests/regression.at (Invalid inputs): No longer `expecting ";"
13149 or "|"' now that so many other tokens are allowed by the new grammar.
13151 * src/complain.h (current_file): Remove duplicate decl;
13152 current_file is now owned by files.h.
13153 * src/complain.c, src/scan-gram.l: Include files.h.
13155 2002-12-06 Paul Eggert <eggert@twinsun.com>
13157 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
13158 promotes to int; it might be unsigned int.
13159 * data/yacc.c (yy_reduce_print): Likewise.
13161 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
13162 be #defined in the prologue, not in the Bison declarations.
13163 This fixes Debian Bug 102878, reported by Shaul Karl.
13165 2002-12-02 Paul Eggert <eggert@twinsun.com>
13167 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
13168 * lib/strtoul.c: New file, from gnulib.
13169 This fixes a porting bug reported by Peter Klein in
13170 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
13172 2002-11-30 Paul Eggert <eggert@twinsun.com>
13174 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
13175 and put only a forward declaration in the prologue. This is for
13176 consistency with the other scanner helper functions.
13178 Type clashes now generate warnings, not errors, since it
13179 appears that POSIX may allow some grammars with type clashes.
13180 * src/reader.c (grammar_current_rule_check): Warn about
13181 type clashes instead of complaining.
13182 * tests/input.at (Type Clashes): Expect warnings, not complaints.
13184 Add Yacc library, since POSIX requires it.
13185 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
13186 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
13187 * lib/main.c, lib/yyerror.c: New files.
13189 gram_error can be static; it need not be extern.
13190 * src/reader.h (gram_error): Remove decl.
13191 * src/parse-gram.y (gram_error): Now static. Add static decl.
13192 (print_token_value): Omit parameter names from forward decl,
13195 2002-11-29 Paul Eggert <eggert@twinsun.com>
13197 * doc/bison.texinfo: Emphasize that yylex and yyerror must
13198 be declared before being used. E.g., one should typically
13199 declare them in the prologue. Use GNU coding style in examples.
13200 Put "const" consistently after the type it modifies. Mention
13201 that C99 supports "inline". Mention that yyerror traditionally
13204 %parse-param and %lex-param now take just one argument, the
13205 declaration; the argument name is deduced from the declaration.
13207 * doc/bison.texinfo (Parser Function, Pure Calling, Error
13208 Reporting, Table of Symbols): Document this.
13209 * src/parse-gram.y (add_param): New function.
13211 (declaration): Implement new rule for %parse-param and %lex-param.
13212 * src/scan-gram.l: "," now elicits a warning, rather than being
13213 a token; this is more compatible with byacc.
13214 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
13216 2002-11-27 Paul Eggert <eggert@twinsun.com>
13218 Rename identifiers to avoid real and potential collisions.
13220 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
13221 to avoid collision with lex macro described by Bruce Lilly in
13222 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
13223 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
13224 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
13225 * src/parse-gram.y (print_token_value): Renamed from yyprint.
13227 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
13228 The name "yycontrol" violates the name space rules, and this stuff
13229 wasn't being used anyway.
13230 (input): Remove action; this stuff wasn't being used.
13231 (gram_error): Rename local variable yylloc -> loc.
13232 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
13233 (YY_DECL): Don't use "yy" at start of local variables.
13234 All uses changed, e.g., yylloc -> loc.
13235 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
13236 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
13237 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
13238 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
13240 * src/parse-gram.y (gram_error): loc is now const *.
13241 * src/reader.h (gram_error): Likewise.
13243 2002-11-24 Paul Eggert <eggert@twinsun.com>
13247 * tests/actions.at (Actions after errors): Use an output format
13248 more similar to that of the Printers and Destructors test.
13249 Test the position of the ';' token too.
13250 (Printers and Destructors): Likewise.
13251 (Printers and Destructors: %glr-parser): Remove for now, to avoid
13252 unnecessarily alarming people when the test fails.
13254 * data/yacc.c (yyerrlab1): Move this label down, so that the
13255 parser does not discard the lookahead token if the user code
13256 invokes YYERROR. This change is required for POSIX conformance.
13258 * lib/error.c: Sync with gnulib.
13260 2002-11-22 Paul Eggert <eggert@twinsun.com>
13262 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
13263 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
13264 * lib/xmalloc.c: Likewise.
13266 2002-11-20 Paul Eggert <eggert@twinsun.com>
13268 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
13270 2002-11-20 Paul Eggert <eggert@twinsun.com>
13272 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
13273 should use `if (! x) abort ();' rather than `assert (x);', and
13274 anyway it's one less thing to worry about configuring.
13276 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
13277 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
13278 and replace all instances of assert with abort.
13279 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
13280 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
13282 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
13283 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
13284 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
13285 hash_find_entry, hash_rehash, hash_insert): Likewise.
13286 * src/conflicts.c (resolve_sr_conflict): Likewise.
13287 * src/lalr.c (set_goto_map, map_goto): Likewise.
13288 * src/nullable.c (nullable_compute): Likewise.
13289 * src/output.c (prepare_rules, token_definitions_output): Likewise.
13290 * src/reader.c (packgram, reader): Likewise.
13291 * src/state.c (state_new, state_free, state_transitions_set,
13292 state_reduction_find): Likewise.
13293 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
13294 symbol_pack): Likewise.
13295 * src/tables.c (conflict_row, pack_vector): Likewise.
13296 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
13297 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
13298 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
13299 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
13301 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
13302 (ARGMATCH_CONSTRAINT): New macro.
13303 (ARGMATCH_ASSERT): Use it.
13305 * src/system.h (verify): New macro.
13306 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
13307 rather than assert.
13308 * src/tables.c (tables_generate): Likewise.
13310 * src/struniq.c (struniq_assert): Now returns void, and aborts
13311 if the assertion is false.
13312 (struniq_assert_p): Remove.
13313 * src/struniq.h: Likewise.
13315 2002-11-18 Paul Eggert <eggert@twinsun.com>
13317 * data/glr.c (yygetLRActions): Replace `yyindex' with
13318 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
13319 This fixes the regression with Sun ONE Studio 7 cc that I reported in
13320 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
13322 2002-11-18 Akim Demaille <akim@epita.fr>
13324 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
13326 From Tim Van Holder.
13328 2002-11-17 Paul Eggert <eggert@twinsun.com>
13330 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
13331 to "SyntaxError" for consistency with my 2002-11-15 change.
13333 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
13334 not define to {}, since this breaks the common use of `YYDPRINTF
13335 ((...));' if a single statement is desired (e.g. before `else').
13336 Work around GCC warnings by surrounding corresponding calls with
13338 (yyhasResolvedValue): Remove unused function.
13339 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
13341 (yyreportSyntaxError): Renamed from yyreportParseError.
13342 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
13344 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
13345 extern when possible. Remove unused initializations.
13347 2002-11-16 Akim Demaille <akim@epita.fr>
13349 Augment the similarity between GLR and LALR traces.
13351 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
13352 (YY_REDUCE_PRINT): New.
13353 (yyparse): Use them.
13354 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
13356 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
13357 state reached after the reduction/recovery, since...
13358 (yyparse, yyprocessOneStack): Report the state we are entering in.
13360 2002-11-16 Akim Demaille <akim@epita.fr>
13362 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
13363 Add support for --trace=skeleton.
13364 * src/scan-skel.l: %option debug.
13365 Scan strings of non-@ or \n instead of character by character.
13366 (scan_skel): Handle trace_skeleton.
13368 (@output_parser_name@, @output_header_name@): ``Restore'' their
13369 support (used to be M4 macros).
13370 * data/yacc.c: Quote larger chunks, a la glr.c.
13371 * data/lalr1.cc: Likewise.
13372 The header guards are no longer available, so use some other
13373 string than `YYLSP_NEEDED'.
13375 2002-11-16 Akim Demaille <akim@epita.fr>
13377 Make the ``Printers and Destructors'' test more verbose, taking
13378 `yacc.c''s behavior as (possibly wrong) reference.
13380 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
13381 instead of fprint on stdout.
13382 Set and report the last_line of the symbols.
13383 Consistently display values and locations.
13385 2002-11-16 Paul Eggert <eggert@twinsun.com>
13387 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
13389 2002-11-15 Paul Eggert <eggert@twinsun.com>
13391 * tests/actions.at (Actions after errors): New test case.
13393 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
13394 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
13395 tests/action.at, tests/calc.at, tests/conflicts.at,
13396 tests/cxx-type.at, tests/regression.at:
13397 "parse error" -> "syntax error" for POSIX compatibility.
13398 "parsing stack overflow..." -> "parser stack overflow" so
13399 that code matches Bison documentation.
13401 2002-11-15 Akim Demaille <akim@epita.fr>
13403 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
13404 take two BRACED_CODE, not two string_content.
13405 Free the scanner's obstack when we are done.
13406 (code_content): New.
13407 * tests/calc.at: Adjust.
13408 * doc/bison.texinfo: Adjust.
13409 Also, make sure to include the `,' for these declarations.
13411 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
13413 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
13414 definition; avoids potential autoreconf problems.
13416 2002-11-15 Akim Demaille <akim@epita.fr>
13418 Always check the value returned by yyparse.
13420 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
13421 returned by yyparse.
13422 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
13424 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
13425 returned by yyparse.
13427 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13429 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
13432 2002-11-14 Paul Eggert <eggert@twinsun.com>
13434 * src/output.c (output_skeleton): Call xfopen instead of
13435 duplicating xfopen's body.
13437 Fix bugs reported by Nelson H. F. Beebe in
13438 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
13440 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
13441 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
13442 Group compiler. Instead, use "$CC -E bar.c". Include the .h
13443 file twice in the grammar, as an extra check.
13445 * tests/input.at (Torturing the Scanner): Surround the
13446 backslash-newline tests with "#if 0", to make it less likely that
13447 we'll run into compiler bugs. Bring back solitary \ inside
13448 comment, but add a closing comment to work around HP C bug. Don't
13449 test backslash-newline in C character constant.
13451 2002-11-14 Akim Demaille <akim@epita.fr>
13453 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
13454 status of the compiler.
13455 Calling `exit 1' is no longer needed.
13456 Reported by Nelson H. F. Beebe.
13458 2002-11-14 Akim Demaille <akim@epita.fr>
13460 * tests/atlocal.in (CPPFLAGS): We have config.h.

13466 grammars that are to be compiled.
13467 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
13468 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.

13473 * doc/bison.texinfo: Various formatting changes (alignments in
13474 samples, additional @group/@end group, GCS in samples.
13475 Use @deffn instead of simple @table to define the directives,
13476 macros, variables etc.
13478 2002-11-13 Paul Eggert <eggert@twinsun.com>
13480 Fix some bugs reported by Albert Chin-A-Young in
13481 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
13483 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
13484 -o c"; the HP C compiler chatters during compilation.
13485 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
13486 * tests/headers.at (export YYLTYPE): Likewise.
13488 * tests/input.at (Torturing the Scanner): Remove lines containing
13489 solitary backslashes, as they tickle a bug in the HP C compiler.
13491 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
13492 comments, since they're not portable. Use GNU coding style.
13494 2002-11-13 Akim Demaille <akim@epita.fr>
13496 * data/yacc.c: Leave bigger chunks of quoted text.

13514 (bitset_set, bitset_reset, bitset_test): Rename local vars
13515 to avoid shadowing warnings by GCC.
13517 * data/glr.c (inline): Remove #define. It's the user's
13518 responsibility to #define it away, just like 'const'.
13519 This fixes one of the bugs reported by Nelson H. F. Beebe in
13520 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
13522 * Makefile.maint (po-check): Scan .l and .y files instead of the
13523 .c and the .h files that they generate. This fixes the bug
13524 reported by Tim Van Holder in:
13525 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
13526 Look for N_ as well as for _. Try to avoid matching #define for
13528 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
13529 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
13530 * src/scan-gram.l: Revamp regular expressions so that " and '
13531 do not confuse xgettext.
13533 * src/struniq.h (struniq_new): Do not declare the return type
13534 to be 'const'; this violates the C standard.
13535 * src/struniq.c (struniq_new): Likewise.
13537 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
13539 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
13540 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq

13564 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
13565 Use it to test the GLR parser.
13567 2002-11-12 Akim Demaille <akim@epita.fr>
13569 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton

13572 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
13573 (YYDSYMPRINT): New.

13577 (b4_yysymprint_generate): invoke.
13578 * data/c.m4 (b4_yysymprint_generate): New.
13579 Accept pointers as arguments, as opposed to the version from
13581 (b4_yydestruct_generate): Likewise.
13582 * tests/cations.at (Printers and Destructors): Use Bison directives
13583 instead of CPP macros.
13584 Don't rely on internal details.
13586 2002-11-12 Akim Demaille <akim@epita.fr>
13588 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
13589 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
13590 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
13591 it against YYEMPTY and so forth), work on yytoken (i.e., set
13592 it to YYEMPTY etc.).
13593 (yydestruct): Replace with a b4_yydestruct_generate invocation.
13594 (b4_symbol_actions): Remove.
13595 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
13596 for 0, end-of-input.
13598 2002-11-12 Akim Demaille <akim@epita.fr>
13600 * doc/bison.texinfo (Destructor Decl): New.
13602 2002-11-12 Akim Demaille <akim@epita.fr>
13604 * src/tables.c (tables_generate): Use free for pointers that
13605 cannot be NULL, not XFREE.

13615 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
13617 * src/scan-gram.l (last_string): Is global to the file, not to
13619 * src/parse-gram.y (input): Don't append the epilogue here,
13620 (epilogue.opt): do it here, and free the scanner's obstack.

13622 (epilogue_augment): this.
13623 * data/c.m4 (b4_epilogue): Defaults to empty.

13681 2002-11-11 Paul Eggert <eggert@twinsun.com>
13683 Revamp to fix many (but not all) of the C- and M4-related quoting
13684 problems. Among other things, this fixes the Bison bug reported
13685 by Jan Hubicka when processing the Bash grammar; see:
13686 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
13688 Use new @ escapes consistently. Represent brackets with @{ and @}
13689 rather than @<:@ and @:>@, since this works a bit better with dumb
13690 editors like vi. Represent @ with @@, since @ is now consistently
13691 an escape. Use @oline@ and @ofile@ rather than __oline__ and
13692 __ofile__, to avoid unexpected expansions. Similarly, use @output
13693 rather than #output.
13695 * data/c.m4 (b4_copyright): Omit file name from comment, since
13696 the file name could contain "*/".
13697 (b4_synclines_flag): Don't quote the 2nd argument; it should already
13698 be quoted. All uses changed.
13700 * data/glr.c: Use new @ escapes consistently.
13701 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
13702 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
13703 Remove, since they couldn't handle arbitrary characters in file
13705 * data/lalr1.cc: Likewise.
13706 * data/yacc.c: Likewise.
13708 * src/files.c (output_infix): Remove; all uses removed.
13709 * src/files.h: Likewise.
13711 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
13712 mishandled funny characters in file names, and anyway it isn't
13714 * data/yacc.c: Likewise.
13715 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
13717 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
13718 * data/yacc.c: Likewise.
13720 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
13722 (muscle_init): Quote filename as a C string.
13723 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
13724 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
13725 * src/output.c (escaped_file_name_output): New function.
13726 (prepare_symbols): Quote tokens for M4.
13727 (prepare): Don't insert output_infix, output_prefix,
13728 output_parser_name, output_header_name; this is now down by scan-skel.
13729 Insert skeleton as a C string.
13731 * src/output.c (user_actions_output, symbol_destructors_output,
13732 symbol_printers_output): Quote filenames for C and M4.
13733 * src/reader.c (prologue_augment, epilogue_set): Likewise.
13735 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
13736 escapes other than \\ and \'; this simplifies the code.
13737 (<SC_STRING>): Likewise, for \\ and \".
13738 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
13739 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
13740 Use new escapes @{ and @} for [ and ].
13742 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
13743 them with auto vars.
13744 Switch to new escape scheme, where @ is the escape character uniformly.
13745 Abort if a stray escape character is found. Avoid unbounded input
13746 buffer when parsing non-escaped text.
13748 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
13749 __oline__, #output, $@, and @{ do not have unintended meanings.
13751 2002-11-09 Paul Eggert <eggert@twinsun.com>
13753 Fix the test failure due to GCC warnings described in
13754 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
13755 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
13756 evaluate to 0 if it's impossible for NINF to be in the respective
13758 (yygetLRActions, yyrecoverParseError): Use them.
13760 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
13761 counted in the token inserted at end of file. Now takes
13762 location_t *, not location_t, so that the location can be
13763 adjusted. All uses changed.
13765 * tests/regression.at (Invalid inputs): Adjust wording in
13766 diagnostic to match the new behavior.
13768 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
13769 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
13770 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
13771 abort ();'. This reduces the runtime of the "Many lookaheads"
13772 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
13775 2002-11-07 Paul Eggert <eggert@twinsun.com>
13777 * src/parse-gram.y (CHARACTER): Remove unused token.
13780 * src/scan-gram.l: Remove stack option. We no longer use the
13781 stack, since the stack was never deeper than 1; instead, use the
13782 new auto var c_context to record the stacked value.
13784 Remove nounput option. At an unexpected end of file, we now unput
13785 the minimal input necessary to end cleanly; this simplifies the
13788 Avoid unbounded token sizes where this is easy.
13790 (unexpected_end_of_file): New function.
13791 Use it to systematize the error message on unexpected EOF.
13792 (last-string): Now auto, not static.
13793 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
13794 (scanner_last_string_free): Remove; not used.
13795 (percent_percent_count): Move decl to just before use.
13796 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
13797 not the (never otherwised-used) CHARACTER.
13799 2002-11-07 Akim Demaille <akim@epita.fr>

13854 2002-11-05 Paul Eggert <eggert@twinsun.com>
13856 * src/scan-gram.l: Use more accurate diagnostics, e.g.

13858 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
13861 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.

13914 Use b4_identification.
13915 Propagate b4_pure_args where needed to pass them to yyerror.
13916 * data/glr.m4 (b4_parse_param): Remove.
13917 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)

13919 Use b4_identification.
13920 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
13921 b4_user_formals and b4_user_args.
13922 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
13923 (yyreportAmbiguity): When using a pure parser, also need
13924 the location, and the parse-params.
13926 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
13927 When using a pure parser, also need the parse-params.
13929 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
13930 (%pure-parser + %parse-param) LALR and GLR parsers.
13931 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
13932 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
13933 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
13934 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
13935 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
13936 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
13937 * doc/bison.texinfo: Untabify the whole file.
13938 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
13939 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
13940 (Error Reporting): Adjust to these new directives.
13941 Document %error-verbose, deprecate YYERROR_VERBOSE.
13943 2002-11-03 Akim Demaille <akim@epita.fr>
13945 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
13946 AT_CHECK_CALC_GLR invocations to use % directives, instead of
13947 command line options.
13948 * tests/cxx-type.at: Formatting changes.
13950 2002-11-03 Paul Eggert <eggert@twinsun.com>
13952 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
13953 to count columns correctly, and to check for invalid inputs.
13955 Use mbsnwidth to count columns correctly. Account for tabs, too.
13956 Include mbswidth.h.
13957 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
13958 (extend_location): New function.
13959 (YY_LINES): Remove.
13961 Handle CRLF in C code rather than in Lex code.
13962 (YY_INPUT): New macro.
13963 (no_cr_read): New function.
13965 Scan UCNs, even though we don't fully handle them yet.
13966 (convert_ucn_to_byte): New function.
13968 Handle backslash-newline correctly in C code.
13969 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
13970 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
13972 (tag, splice): New EREs. Do not allow NUL or newline in tags.
13973 Use {splice} wherever C allows backslash-newline.
13974 YY_STEP after space, newline, vertical-tab.
13975 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
13977 (letter, id): Don't assume ASCII; e.g., spell out a-z.
13979 ({int}, handle_action_dollar, handle_action_at): Check for integer
13982 (YY_STEP): Omit trailing semicolon, so that it's more like C.
13984 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
13985 as well as \000. Check for UCHAR_MAX, not 255.
13986 Allow \x with an arbitrary positive number of digits, as in C.
13987 Check for overflow here.
13988 Allow \? and UCNs, for compatibility with C.
13990 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
13991 with quote slot used by complain_at.
13993 * tests/input.at: Add tests for backslash-newline, m4 quotes
13994 in symbols, long literals, and funny escapes in strings.
13996 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
13997 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
13998 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
13999 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
14000 * m4/mbswidth.m4: New file, from GNU coreutils.
14002 * doc/bison.texinfo (Grammar Outline): Document // comments.
14003 (Symbols): Document that trigraphs have no special meaning in Bison,
14004 nor is backslash-newline allowed.
14005 (Actions): Document that trigraphs have no special meaning.
14007 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
14010 2002-11-02 Paul Eggert <eggert@twinsun.com>
14012 * src/reader.c: Don't include quote.h; not needed.
14013 (get_merge_function): Reword warning to be consistent with
14014 type clash diagnostic in grammar_current_rule_check.
14016 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
14017 bug in trigraph handling.
14019 * src/output.c (prepare_symbols): When printing token names,
14020 escape "[" as "@<:@" and likewise for "]".
14022 * src/system.h (errno): Remove declaration, as we are now
14023 assuming C89 or better, and C89 guarantees errno.
14025 2002-10-30 Paul Eggert <eggert@twinsun.com>
14027 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
14028 Check for close failures.
14029 * src/files.h (xfclose): Return void, not int, since it always
14031 * src/files.c (xfclose): Likewise. Report I/O error if ferror
14033 * src/output.c (output_skeleton): Use xfclose rather than fclose
14034 and ferror. xfclose now checks ferror.
14036 * data/glr.c (YYLEFTMOST_STATE): Remove.
14037 (yyreportTree): Use a stack-based leftmost state. This avoids
14038 our continuing battles with bogus warnings about initializers.
14040 2002-10-30 Akim Demaille <akim@epita.fr>
14042 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
14045 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14047 * tests/glr-regr1.at: New test for reported regressions.
14048 * tests/testsuite.at: Add glr-regr1.at test.
14049 * tests/Makefile.am: Add glr-regr1.at test.
14051 2002-10-24 Paul Eggert <eggert@twinsun.com>
14055 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
14056 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
14057 we use malloc. Don't assume 'A' through 'Z' are contiguous.
14058 Don't assume strdup exists; POSIX says its an XSI extension.
14059 Check for buffer overflow on input.
14061 2002-10-24 Akim Demaille <akim@epita.fr>
14063 * src/output.c (output_skeleton): Don't disable M4sugar comments
14064 too soon: it results in comments being expanded.
14065 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
14068 2002-10-24 Akim Demaille <akim@epita.fr>
14070 * data/yacc.c (m4_int_type): New.
14071 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
14072 char' as only yacc.c wants K&R portability.
14073 * data/glr.c (yysigned_char): Remove.
14074 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
14075 Reported by Quoc Peyrot.
14077 2002-10-23 Paul Eggert <eggert@twinsun.com>
14079 * src/main.c (main): With --trace=time, report times even if a
14080 non-fatal error occurs. Formerly, the times were reported in some
14081 such cases but not in others.
14082 * src/reader.c (reader): Just return if a complaint has been issued,
14083 instead of exiting, so that 'main' can report times.
14085 2002-10-22 Akim Demaille <akim@epita.fr>
14087 * src/system.h: Include sys/types.
14088 Reported by Bert Deknuydt.
14090 2002-10-23 Paul Eggert <eggert@twinsun.com>
14092 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
14093 Suggested by Art Haas.
14095 2002-10-22 Paul Eggert <eggert@twinsun.com>
14097 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
14098 decl; not needed any more.
14099 * src/main.c (main): Use return to exit, undoing yesterday's change.
14100 The last OS that we could find where this wouldn't work is
14101 SunOS 3.5, and that's too old to worry about now.
14103 * data/glr.c (struct yyltype): Define members even when not
14104 doing locations. This is more consistent with yacc.c, and it
14105 works around the following bug reports:
14106 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
14107 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
14109 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
14110 @acronym consistently. Standardize on "Yacc" instead of "YACC",
14111 "Algol" instead of "ALGOL". Give a bit more history about BNF.
14113 2002-10-22 Akim Demaille <akim@epita.fr>
14115 * data/README: New.
14117 2002-10-21 Paul Eggert <eggert@twinsun.com>
14119 Be consistent about 'bool'; the old code used an enum in one
14120 module and an int in another, and this violates the C standard.
14121 * m4/stdbool.m4: New file, from coreutils 4.5.3.
14122 * configure.ac (AC_HEADER_STDBOOL): Add.
14123 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
14124 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
14125 * src/symtab.c (hash_compare_symbol_t): Likewise.
14126 * src/system.h (bool, false, true): Use a definition consistent
14127 with ../lib/hash.c. All uses changed.
14129 * src/complain.c (warning_issued): Renamed from warn_message_count,
14130 so that we needn't worry about integer overflow (!).
14131 Now of type bool. All uses changed.
14132 (complaint_issued): Renamed from complain_message_count; likewise.
14134 * src/main.c (main): Use exit to exit with failure.
14136 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
14137 rather than 1 and 0.
14138 * src/main.c (main): Likewise.
14139 * src/getargs.c (getargs): Likewise.
14140 * src/reader.c (reader): Likewise.
14142 * src/getarg.c (getargs): Remove duplicate code for
14143 "Try `bison --help'".
14145 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
14146 What was that "2" for?
14148 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
14149 * src/getargs.c (usage): Likewise.
14151 * src/getargs.c (getargs): When there are too few operands, report
14152 the last one. When there are too many, report the first extra
14153 one. This is how diffutils does it.
14155 2002-10-20 Paul Eggert <eggert@twinsun.com>
14157 Remove K&R vestiges.
14158 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
14159 * src/complain.c (VA_START): Remove. Assume prototypes.
14160 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
14161 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
14162 fatal): Assume prototypes.
14163 * src/complain.h: Assume prototypes.
14164 * src/system.h (PARAMS): Remove.
14165 Include <limits.h> unconditionally, since it's guaranteeed even
14166 for a freestanding C89 compiler.
14167 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
14168 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
14170 2002-10-20 Akim Demaille <akim@epita.fr>
14172 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
14173 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
14174 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
14175 (yyresolveStates, yyresolveAction, yyresolveStack)
14176 (yyprocessOneStack): Use them.
14177 (yy_reduce_print): New.
14178 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
14180 2002-10-20 Akim Demaille <akim@epita.fr>
14182 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
14183 arguments and output `void'.
14184 (b4_c_function): Rename as...
14185 (b4_c_function_def): this.
14186 (b4_c_function_decl, b4_c_ansi_function_def)
14187 (b4_c_ansi_function_decl): New.
14188 Change the interpretation of the arguments: before `int, foo', now
14190 * data/yacc.c (yyparse): Prototype and define thanks to these.
14191 Adjust b4_c_function_def uses.
14192 * data/glr.c (yyparse): Likewise, but ANSI only.
14194 2002-10-20 Akim Demaille <akim@epita.fr>
14196 * src/output.c (prepare): Move the definition of `tokens_number',
14197 `nterms_number', `undef_token_number', `user_token_number_max'
14199 (prepare_tokens): Here.
14200 (prepare_tokens): Rename as...
14201 (prepare_symbols): this.
14202 (prepare): Move the definition of `rules_number' to...
14203 (prepare_rules): here.
14204 (prepare): Move the definition of `last', `final_state_number',
14205 `states_number' to...
14206 (prepare_states): here.
14207 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
14209 2002-10-20 Akim Demaille <akim@epita.fr>
14211 * src/tables.h, src/tables.c, src/output.c: Comment changes.
14213 2002-10-20 Akim Demaille <akim@epita.fr>
14215 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
14218 2002-10-20 Akim Demaille <akim@epita.fr>
14220 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
14221 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
14223 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
14225 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
14226 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
14229 2002-10-19 Paul Eggert <eggert@twinsun.com>
14231 Do not create a temporary file, as that involves security and
14232 cleanup headaches. Instead, use a pair of pipes.
14233 Derived from a suggestion by Florian Krohm.
14234 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
14235 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
14236 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
14237 (BISON_PREREQ_SUBPIPE): Add.
14238 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
14239 Add subpipe.h, subpipe.c.
14240 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.

14244 (scan_skel): New decl.
14245 (output_skeleton): Use pipe rather than temporary file for m4 input.

14247 Check for pipe I/O error.
14248 * src/scan-skel.l (readpipe): Remove decl.
14249 (scan_skel): New function, to be used in place of m4_invoke.
14250 Read from stream rather than file.
14252 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
14253 float, as this generates a warning on Solaris 8 + GCC 3.2 with
14254 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
14255 this generates a more-accurate value anyway.
14257 * lib/timevar.c (timervar_accumulate): Rename locals to
14258 avoid confusion with similarly-named more-global.
14259 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
14261 * src/output.c (prepare): Use xstrdup to convert char const *
14262 to char *, to avoid GCC warning.
14264 2002-10-19 Akim Demaille <akim@epita.fr>
14266 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
14267 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
14268 Use them to have `calc.y' ready for %pure-parser.
14269 * data/yacc.c (YYLEX): Pass a yylex return type to
14270 b4_c_function_call.
14272 2002-10-19 Akim Demaille <akim@epita.fr>
14274 Prototype support of %lex-param and %parse-param.
14276 * src/parse-gram.y: Add the definition of the %lex-param and
14277 %parse-param tokens, plus their rules.
14278 Drop the `_' version of %glr-parser.
14280 * src/scan-gram.l (INITIAL): Scan them.

14284 (muscle_entry_s): The `value' member is no longer const.
14285 Adjust all dependencies.
14286 * src/muscle_tab.c (muscle_init): Adjust: use
14287 MUSCLE_INSERT_STRING.
14288 Initialize the obstack earlier.
14289 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
14290 (muscle_pair_list_grow): New.
14291 * data/c.m4 (b4_c_function_call, b4_c_args): New.
14292 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
14293 * tests/calc.at: Use %locations, not --locations.
14294 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
14296 2002-10-19 Akim Demaille <akim@epita.fr>
14298 * src/getargs.c (usage): Take status as argument and exit
14300 Report the traditional `Try ... --help' message when status != 0.
14301 (usage, version): Don't take a FILE * as arg, it is pointless.
14302 (getargs): When there is an incorrect number of arguments, make it
14303 an error, and report it GNUlically thanks to `usage ()'.
14305 2002-10-18 Paul Eggert <eggert@twinsun.com>
14307 * data/glr.c (yyreportParseError): Don't assume that sprintf
14308 yields the length of the printed string, as this is not true
14309 on SunOS 4.1.4. Reported by Peter Klein.
14311 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
14312 * tests/conflicts.at (%nonassoc and eof): Likewise.
14313 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
14315 2002-10-17 Akim Demaille <akim@epita.fr>
14317 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
14318 * src/getargs.c (trace_types, trace_args): Adjust.
14319 * src/reader.c (grammar_current_rule_prec_set)
14320 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
14321 Standardize error messages.
14322 And s/@prec/%prec/!
14323 (reader): Use trace_flag to enable scanner/parser debugging,
14324 instead of an adhoc scheme.
14325 * src/scan-gram.l: Remove trailing debugging code.
14327 2002-10-16 Paul Eggert <eggert@twinsun.com>
14329 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
14332 * NEWS: Officially drop support for building Bison with K&R C,
14333 since it didn't work anyway and it's not worth worrying about.
14334 * Makefile.maint (wget_files): Remove ansi2knr.c.
14335 (ansi2knr.c-url_prefix): Remove.
14336 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
14337 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
14338 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
14340 2002-10-15 Paul Eggert <eggert@twinsun.com>
14342 Stop using the "enum_" trick for K&R-style function definitions;
14343 it confused me, and I was the author! Instead, assume that people
14344 who want to use K&R C compilers (when using these modules in GCC,
14345 perhaps?) will run ansi2knr.
14347 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
14348 All uses of "enum_" changed to "enum ".
14349 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
14350 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
14352 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

14477 Let nondeterministic skeletons be usable with deterministic
14480 With the patch, GAWK compiled by GCC without -O2 passes its test
14481 suite using a GLR parser driven by LALR tables. It fails with -O2
14482 because `struct stat' gives two different answers on my machine:
14483 88 (definition of an auto var) and later 96 (memset on this var).
14484 Hence the stack is badly corrumpted. The headers inclusion is to
14485 blame: if I move the awk.h inclusion before GLR's system header
14486 inclusion, the two struct stat have the same size.
14488 * src/tables.c (pack_table): Always create conflict_table.
14489 (token_actions): Always create conflict_list.

14520 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
14521 (yyltype): Remove the yy prefix from the member names.
14522 (yytable): Complete its comment.
14523 (yygetLRActions): Map error action number from YYTABLE from
14525 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
14526 (which was a bug: it should have been YYTABEL_NINF, and yet it was
14527 not satisfying as we could compare an YYACTION computed from
14528 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
14529 only value for error actions.
14530 (yyreportParseError): In verbose parse error messages, don't issue
14531 `error' in the list of expected tokens.
14532 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
14533 next action to perform to match glr.c's decoding.

14540 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
14541 because the Bison parser reads the second action before reducing
14543 * src/scan-gram.l (rule_length): New static var.
14544 Use it to keep track of the rule length in the scanner, since
14545 we can't expect the parser to be in lock-step sync with the scanner.
14546 (handle_action_dollar, handle_action_at): Use this var.

14555 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
14556 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
14558 * lib/timevar.c: Update copyright date and clarify comments.
14559 (get_time) [IN_GCC]: Keep the GCC version for reference.
14561 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
14562 GCC version as of today, then merge Bison's changes.
14563 Change "GCC" to "Bison" in copyright notice. timevar.def's
14564 author is Akim, so change that too.

14699 the same width as int. This reapplies a hunk of the 2002-08-12 patch
14700 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,

14714 signifies end-of-input. Warn about negative chars. Mention
14715 the portable Standard C character set.
14717 The GNU coding standard says CFLAGS and YFLAGS are reserved

15061 outside the C locale.

15064 this is a GCC extension and is not portable to other compilers.

15300 token_translations instead of `0'.
15301 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
15303 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
15304 for the time being: %locations ought to provide it to yyerror.

17147 (reader, grammar_free, readgram, token_translations_init)
17148 (packsymbols): Adjust.
17149 (reader): Number the predefined tokens.
17150 * src/reduce.c (inaccessable_symbols): Just use hard coded numbers

17173 Member `associativity' removed: useless.
17174 * src/reduce.c, src/conflicts.c: Adjust.
17176 2002-04-07 Akim Demaille <akim@epita.fr>
17178 * src/lalr.c, src/LR0.c, src/closure.c, src/gram.c, src/reduce.c:

17201 to reorder ritem itself.
17203 * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
17205 2002-04-07 Akim Demaille <akim@epita.fr>
17207 Be sure never to walk through RITEMS, but use only data related to

17210 * src/output.c (output_token_translations): Rename as...
17211 (prepare_tokens): this.
17212 In addition to `translate', prepare the muscles `tname' and

17226 * src/LR0.c (new_state): Display `nstates' as the name of the
17227 newly created state.
17228 Adjust to initialize first_state and last_state if needed.
17229 Be sure to distinguish the initial from the final state.
17230 (new_states): Create the itemset of the initial state, and use
17232 * src/closure.c (closure): Now that the initial state has its
17233 items properly set, there is no need for a special case when
17234 creating `ruleset'.
17236 As a result, now the rule 0, reducing to $axiom, is visible in the
17237 outputs. Adjust the test suite.

17272 the usefulness of a rule, as useless rules are beyond `nrules + 1'.

17275 2002-04-07 Akim Demaille <akim@epita.fr>
17277 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
17278 lacking `+ 1' to nrules, Bison reported as useless a token if it
17279 was used solely to set the precedence of the last rule...
17281 2002-04-07 Akim Demaille <akim@epita.fr>
17283 * data/bison.c++, data/bison.simple: Don't output the current file
17284 name in #line, to avoid useless diffs between two identical
17285 outputs under different names.
17287 2002-04-07 Akim Demaille <akim@epita.fr>
17289 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

17305 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
17306 RHS, instead of being an index in RITEMS.

17311 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

17644 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
17646 * data/bison.c++: Fix m4 quoting in comments.
17648 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
17650 * data/bison.c++: Adjust the parser code. Fix some muscles that were
17651 not expanded by m4.
17653 2002-02-05 Akim Demaille <akim@epita.fr>
17655 * data/bison.c++: Adjust to the M4 back end.
17656 More is certainly needed.
17658 2002-02-05 Akim Demaille <akim@epita.fr>
17660 Give a try to M4 as a back end.
17662 * lib/readpipe.c: New, from wdiff.
17663 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
17665 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
17666 specific values. Now it is m4 that performs the lookup.
17667 * src/parse-skel.y: Remove.
17668 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
17669 * src/output.c (actions_output, guards_output)
17670 (token_definitions_output): No longer keeps track of the output
17671 line number, hence remove the second argument.
17672 (guards_output): Check against the guard member of a rule, not the
17675 (output_skeleton): Don't look for the skeleton location, let m4 do
17677 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
17679 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
17680 (prepare): Given that for the time being changesyntax is not
17681 usable in M4, rename the muscles using `-' to `_'.
17682 Define `defines_flag', `output_parser_name' and `output_header_name'.
17683 * src/output.h (actions_output, guards_output)
17684 (token_definitions_output): Adjust prototypes.
17685 * src/scan-skel.l: Instead of scanning the skeletons, it now
17686 processes the output of m4: `__oline__' and `#output'.
17687 * data/bison.simple: Adjust to be used by M4(sugar).
17688 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
17690 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
17691 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
17692 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
17693 shamelessly stolen from CVS Autoconf.
17695 2002-02-05 Akim Demaille <akim@epita.fr>
17697 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
17698 * configure.in: Check for the declarations of free and malloc.
17699 * src/muscle_tab.c: Adjust.
17701 2002-02-05 Akim Demaille <akim@epita.fr>
17703 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
17704 which have no values.
17706 2002-02-05 Akim Demaille <akim@epita.fr>
17708 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
17711 2002-01-29 Paul Eggert <eggert@twinsun.com>
17713 * src/bison.simple (YYSIZE_T): Do not define merely because
17714 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
17715 On some platforms, <alloca.h> does not declare YYSTD (size_t).
17717 2002-01-27 Akim Demaille <akim@epita.fr>
17719 Fix `%nonassoc and eof'.
17721 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
17722 which were not properly copied! Replace
17723 memcpy (res->errs, src->errs, src->nerrs);
17725 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
17727 * tests/regression.at (%nonassoc and eof): Adjust to newest
17728 Autotest: `.' is not in the PATH.
17730 2002-01-27 Akim Demaille <akim@epita.fr>
17732 * tests/sets.at (AT_EXTRACT_SETS): New.
17733 (Nullable): Use it.
17736 2002-01-26 Akim Demaille <akim@epita.fr>
17738 * tests/actions.at, tests/calc.at, tests/headers.at,
17739 * tests/torture.at: Adjust to the newest Autotest which no longer
17740 forces `.' in the PATH.
17742 2002-01-25 Akim Demaille <akim@epita.fr>
17744 * tests/regression.at (%nonassoc and eof): New.
17745 Suggested by Robert Anisko.
17747 2002-01-24 Akim Demaille <akim@epita.fr>
17749 Bison dumps core when trying to complain about broken input files.
17750 Reported by Cris van Pelt.
17752 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
17753 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
17755 (Invalid inputs): Strengthen: exercise parse_percent_token.
17757 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
17759 * src/Makefile.am: Add bison.c++.
17760 * src/bison.c++: New skeleton.
17762 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
17766 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
17768 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
17770 2002-01-20 Marc Autret <marc@gnu.org>
17772 * src/files.c (compute_output_file_names): Fix
17774 2002-01-20 Marc Autret <marc@gnu.org>
17776 * tests/output.at: New test.
17777 * src/files.c (compute_base_names): Don't map extensions when
17778 the YACC flag is set, use defaults.
17779 Reported by Evgeny Stambulchik.
17781 2002-01-20 Marc Autret <marc@gnu.org>
17783 * src/system.h: Need to define __attribute__ away for non-GCC
17784 compilers as well (i.e., the vendor C compiler).
17785 Suggested by Albert Chin-A-Young.
17787 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
17789 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
17790 canonical definition.
17791 * src/system.h: Use the canonical definition for PARAMS (avoids
17792 a conflict with the macro from lib/hash.h).
17794 2002-01-11 Akim Demaille <akim@epita.fr>
17796 * configure.in: Use AC_FUNC_STRNLEN.
17797 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
17799 2002-01-09 Akim Demaille <akim@epita.fr>
17801 * src/files.c, src/files.h (output_infix): New.
17802 (tab_extension): Remove.
17803 (compute_base_names): Compute the former, drop the latter.
17804 * src/output.c (prepare): Insert the muscles `output-infix', and
17806 * src/parse-skel.y (string, string.1): New.
17807 (section.header): Use it.
17808 (section.yacc): Remove.
17809 (prefix): Remove too.
17810 * src/scan-skel.l: Adjust.
17811 * src/bison.simple, src/bison.hairy: Adjust.
17813 2002-01-09 Akim Demaille <akim@epita.fr>
17815 * configure.in (WERROR_CFLAGS): Compute it.
17816 * src/Makefile.am (CFLAGS): Pass it.
17817 * tests/atlocal.in (CFLAGS): Idem.
17818 * src/files.c: Fix a few warnings.
17819 (get_extension_index): Remove, unused.
17821 2002-01-08 Akim Demaille <akim@epita.fr>
17823 * src/getargs.c (AS_FILE_NAME): New.
17824 (getargs): Use it to convert DOSish file names.
17825 * src/files.c (base_name): Rename as full_base_name to avoid
17826 clashes with `base_name ()'.
17827 (filename_split): New.
17828 (compute_base_names): N-th rewrite, using filename_split.
17830 2002-01-08 Akim Demaille <akim@epita.fr>
17832 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
17833 New, stolen from the Fileutils 4.1.
17834 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
17835 * configure.in: Check for the presence of memrchr, and of its
17838 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
17840 * lib/hash.h (__P): Added definition for this macro.
17841 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
17842 BUILT_SOURCES, to ensure they are generated first.
17843 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
17844 %error-verbose to allow bootstrapping with bison 1.30x.
17846 2002-01-06 Akim Demaille <akim@epita.fr>
17848 * src/reader.c (parse_braces): Don't fetch the next char, the
17849 convention is to fetch on entry.
17850 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
17851 'switch' without a following semicolon.
17852 * tests/regression.at (braces parsing): New.
17854 2002-01-06 Akim Demaille <akim@epita.fr>
17856 Bison is dead wrong in its RR conflict reports.
17858 * tests/torture.at (GNU Cim Grammar): New.
17859 * src/conflicts.c (count_rr_conflicts): Fix.
17861 2002-01-06 Akim Demaille <akim@epita.fr>
17863 Creating package.m4 from configure.ac causes too many problems.
17865 * tests/Makefile.am (package.m4): Create it by hand,
17866 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
17868 2002-01-06 Akim Demaille <akim@epita.fr>
17870 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
17873 2002-01-04 Paul Eggert <eggert@twinsun.com>
17875 * doc/bison.texinfo (Debugging):
17876 Remove YYSTDERR; it's no longer defined or used.
17877 Also, s/cstdio.h/cstdio/.
17879 2002-01-03 Akim Demaille <akim@epita.fr>
17881 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
17883 2002-01-03 Akim Demaille <akim@epita.fr>
17885 * src/parse-skel.y (process_skeleton): Don't bind the parser's
17886 tracing code to --trace, wait for a better --trace option, with
17889 2002-01-03 Akim Demaille <akim@epita.fr>
17891 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
17892 The ISO C++ standard is extremely clear about it: stderr is
17893 considered a macro, not a regular symbol (see table 94 `Header
17894 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
17895 Therefore std:: does not apply to it. It still does with fprintf.
17896 Also, s/cstdio.h/cstdio/.
17898 2002-01-03 Akim Demaille <akim@epita.fr>
17900 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
17901 for non system headers.
17903 2002-01-02 Akim Demaille <akim@epita.fr>
17905 Equip the skeleton chain with location tracking, runtime trace,
17906 pure parser and scanner.
17908 * src/parse-skel.y: Request a pure parser, locations, and prefix
17910 (%union): Having several members with the same type does not help
17911 type mismatches, simplify.
17912 (YYPRINT, yyprint): New.
17913 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
17914 (skel_error): this.
17916 * src/scan-skel.l: Adjust to these changes.
17917 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
17918 (LOCATION_PRINT, skel_control_t): New.
17920 2001-12-30 Akim Demaille <akim@epita.fr>
17922 * src/parse-skel.y: Get rid of the shift/reduce conflict:
17923 replace `gb' with BLANKS.
17924 * src/scan-skel.l: Adjust.
17926 2001-12-30 Akim Demaille <akim@epita.fr>
17928 * src/system.h: We don't need nor want bcopy.
17929 Throw away MS-DOS crap: we don't need getpid.
17930 * configure.in: We don't need strndup. It was even causing
17931 problems: because Flex includes the headers *before* us,
17932 _GNU_SOURCE is not defined by config.h, and therefore strndup was
17934 * lib/xstrndup.c: New.
17935 * src/scan-skel.l: Use it.
17936 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
17937 * src/parse-skel.y: Use %directives instead of #defines.
17939 2001-12-30 Akim Demaille <akim@epita.fr>
17941 * src/skeleton.h: New.
17942 * src/output.c (output_parser, output_master_parser): Remove, dead
17944 * src/output.h (get_lines_number, actions_output, guards_output)
17945 (token_definitions_output): Prototype them.
17946 * src/parse-skel.y: Add the license notice.
17947 Include output.h and skeleton.h.
17948 (process_skeleton): Returns void, and takes a single parameter.
17949 * src/scan-skel.l: Add the license notice.
17950 Include skeleton.h.
17951 Don't use %option yylineno: it seems that then Flex imagines
17952 REJECT has been used, and therefore it won't reallocate its
17953 buffers (which makes no other sense to me than a bug). It results
17954 in warnings for `unused: yy_flex_realloc'.
17956 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
17958 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17959 (MUSCLE_INSERT_PREFIX): ...to there.
17960 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17961 (MUSCLE_INSERT_PREFIX): Move from here...
17963 * src/bison.hairy: Add a section directive. Put braces around muscle
17964 names. This parser skeleton is still broken, but Bison should not
17965 choke on a bad muscle 'syntax'.
17966 * src/bison.simple: Add a section directive. Put braces around muscle
17969 * src/files.h (strsuffix, stringappend): Add declarations.
17970 (tab_extension): Add declaration.
17971 (short_base_name): Add declaration.
17973 * src/files.c (strsuffix, stringappend): No longer static. These
17974 functions are used in the skeleton parser.
17975 (tab_extension): New.
17976 (compute_base_names): Use the computations done in this function
17977 to guess if the generated parsers should have '.tab' in their
17979 (short_base_name): No longer static.
17981 * src/output.c (output_skeleton): New.
17982 (output): Disable call to output_master_parser, and give a try to
17983 a new skeleton handling system.
17984 (guards_output, actions_output): No longer static.
17985 (token_definitions_output, get_lines_number): No longer static.
17987 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
17989 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
17992 * src/parse-skel.y: New file.
17993 * src/scan-skel.l: New file.
17995 2001-12-29 Akim Demaille <akim@epita.fr>
17997 %name-prefix is broken.
17999 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
18000 Adjust all dependencies.
18001 * tests/headers.at (export YYLTYPE): Strengthen this test: use
18004 Renaming yylval but not yylloc is not consistent. Now we do.
18006 * src/bison.simple: Prefix yylloc if used.
18007 * doc/bison.texinfo (Decl Summary): Document that.
18009 2001-12-29 Akim Demaille <akim@epita.fr>
18011 * doc/bison.texinfo: Promote `%long-directive' over
18013 Remove all references to fixed-output-files, yacc is enough.
18015 2001-12-29 Akim Demaille <akim@epita.fr>
18017 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
18018 user prologue. These are defaults.
18019 * tests/actions.at (Mid-rule actions): Make sure the user can
18020 define YYDEBUG and YYERROR_VERBOSE.
18022 2001-12-29 Akim Demaille <akim@epita.fr>
18024 * src/output.c (header_output): Don't forget to export YYLTYPE and
18026 * tests/headers.at (export YYLTYPE): New, make sure it does.
18027 * tests/regression.at (%union and --defines, Invalid CPP headers):
18029 * tests/headers.at: here.
18031 2001-12-29 Akim Demaille <akim@epita.fr>
18033 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
18035 2001-12-29 Akim Demaille <akim@epita.fr>
18037 * tests/actions.at (Mid-rule actions): Output on a single line
18038 instead of several.
18040 2001-12-29 Akim Demaille <akim@epita.fr>
18042 * doc/bison.texinfo: Formatting changes.
18044 2001-12-29 Akim Demaille <akim@epita.fr>
18046 Don't store the token defs in a muscle, just be ready to output it
18047 on command. Now possible via `symbols'. Fixes a memory leak.
18049 * src/output.c (token_definitions_output): New.
18050 (output_parser, header_output): Use it.
18051 * src/reader.c (symbols_save): Remove.
18053 2001-12-29 Akim Demaille <akim@epita.fr>
18055 * src/bison.simple: Do not provide a default for YYSTYPE and
18056 YYLTYPE before the user's prologue. Otherwise it's hardly... a
18059 2001-12-29 Akim Demaille <akim@epita.fr>
18061 Mid-rule actions are simply... ignored!
18063 * src/reader.c (readgram): Be sure to attach mid-rule actions to
18064 the empty-rule associated to the dummy symbol, not to the host
18066 * tests/actions.at (Mid-rule actions): New.
18068 2001-12-29 Akim Demaille <akim@epita.fr>
18072 * src/reader.c (reader): Free grammar.
18074 2001-12-29 Akim Demaille <akim@epita.fr>
18078 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
18079 since it allocates it for each state, although only one is needed.
18080 (allocate_storage): Do it here.
18082 2001-12-29 Akim Demaille <akim@epita.fr>
18084 * src/options.h, src/options.c (create_long_option_table): Rename
18086 (long_option_table_new): this, with a clearer prototype.
18087 (percent_table): Remove, unused,
18088 * src/getargs.c (getargs): Adjust.
18090 2001-12-29 Akim Demaille <akim@epita.fr>
18092 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
18093 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
18096 2001-12-29 Akim Demaille <akim@epita.fr>
18098 * src/lalr.c (build_relations): Rename `states' as `states1'.
18099 Sorry, I don't understand exactly what it is, no better name...
18101 2001-12-29 Akim Demaille <akim@epita.fr>
18103 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
18104 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
18105 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
18108 2001-12-29 Akim Demaille <akim@epita.fr>
18110 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
18113 2001-12-29 Akim Demaille <akim@epita.fr>
18115 * src/reader.c, src/reader.h (user_toknums): Remove.
18116 Adjust all users to use symbols[i]->user_token_number.
18118 2001-12-29 Akim Demaille <akim@epita.fr>
18120 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
18121 Adjust all users to use symbols[i]->prec or ->assoc.
18123 2001-12-29 Akim Demaille <akim@epita.fr>
18125 * src/reader.c, src/reader.h (tags): Remove.
18126 Adjust all users to use symbols[i]->tag.
18128 2001-12-29 Akim Demaille <akim@epita.fr>
18130 * src/gram.h, src/gram.c (symbols): New, similar to state_table
18132 * src/reader.c (packsymbols): Fill this table.
18134 * src/conflicts.c (resolve_sr_conflict): Adjust.
18135 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
18137 Use symbols[i]->tag instead of tags[i].
18139 2001-12-29 Akim Demaille <akim@epita.fr>
18141 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
18142 In addition, put a comment in there, to replace...
18143 * tests/regression.at (%union and C comments): Remove.
18145 2001-12-29 Akim Demaille <akim@epita.fr>
18147 * tests/regression.at (Web2c Actions): Blindly move the actual
18148 output as expected output. The contents *seem* right to me, but I
18149 can't pretend reading perfectly parser tables... Nonetheless, all
18150 the other tests pass correctly, the table look OK, even though the
18151 presence of `$axiom' is to be noted: AFAICS it is useless (but
18154 2001-12-29 Akim Demaille <akim@epita.fr>
18156 * src/reader.c (readgram): Don't add the rule 0 if there were no
18157 rules read. In other words, add it _after_ having performed
18158 grammar sanity checks.
18159 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
18161 2001-12-29 Akim Demaille <akim@epita.fr>
18163 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
18164 visible, and some states have now a different number.
18166 2001-12-29 Akim Demaille <akim@epita.fr>
18168 * src/reader.c (readgram): Bind the initial rule's lineno to that
18170 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
18171 (Solved SR Conflicts): Adjust rule 0's line number.
18173 2001-12-29 Akim Demaille <akim@epita.fr>
18175 Fix the `GAWK Grammar' failure.
18177 * src/LR0.c (final_state): Initialize to -1 so that we do compute
18178 the reductions of the first state which was mistakenly confused
18179 with the final state because precisely final_state was initialized
18181 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
18182 now noticed by Bison.
18183 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
18184 have a reduction on $default.
18186 2001-12-29 Akim Demaille <akim@epita.fr>
18188 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
18190 * src/closure.c (print_closure): Likewise.
18191 * src/derives.c (print_derives): Likewise.
18192 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
18195 2001-12-29 Akim Demaille <akim@epita.fr>
18197 * src/lalr.c (lookaheads_print): New.
18198 (lalr): Call it when --trace-flag.
18199 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
18202 2001-12-29 Akim Demaille <akim@epita.fr>
18204 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
18205 when walking through ritem, even via rule->rhs.
18206 * src/reduce.c (dump_grammar, useful_production, reduce_output)
18207 (useful_production, useless_nonterminals): Likewise.
18208 (reduce_grammar_tables): Likewise, plus update nritems.
18209 * src/nullable.c (set_nullable): Likewise.
18210 * src/lalr.c (build_relations): Likewise.
18211 * tests/sets.at (Nullable): Adjust.
18212 Fortunately, now, the $axiom is no longer nullable.
18214 2001-12-29 Akim Demaille <akim@epita.fr>
18216 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
18218 * src/gram.c (ritem_longest_rhs): Likewise.
18219 * src/reduce.c (nonterminals_reduce): Likewise.
18220 * src/print_graph.c (print_graph): Likewise.
18221 * src/output.c (output_rule_data): Likewise.
18222 * src/nullable.c (set_nullable): Likewise.
18224 2001-12-29 Akim Demaille <akim@epita.fr>
18226 * src/output.c: Comment changes.
18228 2001-12-27 Paul Eggert <eggert@twinsun.com>
18230 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
18231 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
18232 Sparc, as they were causing more porting problems than the
18233 (minor) performance improvement was worth.
18235 Also, catch up with 1.31's YYSTD.
18237 2001-12-27 Akim Demaille <akim@epita.fr>
18239 * src/output.c (output_gram): Rely on nritems, not the
18240 0-sentinel. See below.
18241 Use -1 as separator, not 0.
18242 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
18243 Rely on -1 as separator in yyrhs, instead of 0.
18244 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
18245 twice `Now at end of input', therefore there are two lines less to
18248 2001-12-27 Akim Demaille <akim@epita.fr>
18250 * tests/regression.at (Unresolved SR Conflicts):
18251 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
18254 2001-12-27 Akim Demaille <akim@epita.fr>
18256 * src/LR0.c (new_state): Recognize the final state by the fact it
18257 is reached by eoftoken.
18258 (insert_start_shifting_state, insert_eof_shifting_state)
18259 (insert_accepting_state, augment_automaton): Remove, since now
18260 these states are automatically computed from the initial state.
18261 (generate_states): Adjust.
18262 * src/print.c: When reporting a rule number to the user, substract
18263 1, so that the axiom rule is rule 0, and the first user rule is 1.
18264 * src/reduce.c: Likewise.
18265 * src/print_graph.c (print_core): For the time being, just as for
18266 the report, depend upon --trace-flags to dump the full set of
18268 * src/reader.c (readgram): Once the grammar read, insert the rule
18269 0: `$axiom: START-SYMBOL $'.
18270 * tests/set.at: Adjust: rule 0 is now displayed, and since the
18271 number of the states has changed (the final state is no longer
18272 necessarily the last), catch up.
18274 2001-12-27 Akim Demaille <akim@epita.fr>
18276 Try to make the use of the eoftoken valid. Given that its value
18277 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
18278 is used instead of > 0 where appropriate, (ii), depend upon nritems
18279 instead of the 0-sentinel.
18281 * src/gram.h, src/gram.c (nritems): New.
18282 Expected to be duplication of nitems, but for the time being...
18283 * src/reader.c (packgram): Assert nritems and nitems are equal.
18284 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
18285 * src/closure.c (print_closure, print_fderives): Likewise.
18286 * src/gram.c (ritem_print): Likewise.
18287 * src/print.c (print_core, print_grammar): Likewise.
18288 * src/print_graph.c: Likewise.
18290 2001-12-27 Akim Demaille <akim@epita.fr>
18292 * src/main.c (main): If there are complains after grammar
18293 reductions, then output the report anyway if requested, then die.
18294 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
18295 * src/reader.c (eoftoken): New.
18296 (parse_token_decl): If the token being defined has value `0', it
18298 (packsymbols): No longer hack `tags' to insert `$' by hand.
18299 Be sure to preserve the value of the eoftoken.
18300 (reader): Make sure eoftoken is defined.
18301 Initialize nsyms to 0: now eoftoken is created just like the others.
18302 * src/print.c (print_grammar): Don't special case the eof token.
18303 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
18304 lie anyway, albeit pleasant.
18305 * tests/calc.at: Exercise error messages with eoftoken.
18306 Change the grammar so that empty input is invalid.
18307 Adjust expectations.
18308 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
18310 2001-12-27 Akim Demaille <akim@epita.fr>
18312 * configure.in: Check the protos of strchr ans strspn.
18313 Replace strchr if needed.
18314 * src/system.h: Provide the protos of strchr, strspn and memchr if
18316 * lib/strchr.c: New.
18317 * src/reader.c (symbols_save): Use strchr.
18319 2001-12-27 Akim Demaille <akim@epita.fr>
18321 * src/print.c, src/print_graph.c (escape): New.
18322 Use it to quote the TAGS outputs.
18323 * src/print_graph.c (print_state): Now errors are in red, and
18324 reductions in green.
18325 Prefer high to wide: output the state number on a line of its own.
18327 2001-12-27 Akim Demaille <akim@epita.fr>
18329 * src/state.h, src/state.c (reductions_new): New.
18330 * src/LR0.c (set_state_table): Let all the states have a
18331 `reductions', even if reduced to 0.

18350 2001-12-27 Akim Demaille <akim@epita.fr>
18352 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
18353 * src/print.c: here.
18354 (lookaheadset, shiftset): New, used as additional storage by
18356 (print_results): Adjust.
18357 (print_shifts, print_gotos, print_errs): New, extracted from...
18358 (print_actions): here.
18359 * src/print_graph.c (print_actions): Remove dead code.
18361 2001-12-27 Akim Demaille <akim@epita.fr>
18363 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
18366 2001-12-27 Akim Demaille <akim@epita.fr>
18368 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
18369 (build_relations): Adjust.

18378 * src/reader.c (packgram): Catch nitems overflows.
18380 2001-12-27 Akim Demaille <akim@epita.fr>
18382 * src/files.c, src/files.h (guard_obstack): Remove.
18383 * src/output.c (output): Adjust.
18384 * src/reader.c (parse_braces): New, factoring...
18385 (copy_action, copy_guard): these two which are renamed as...
18386 (parse_action, parse_guard): these.
18387 As a voluntary consequence, using braces around guards is now
18390 2001-12-27 Akim Demaille <akim@epita.fr>
18392 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
18393 * src/reader.c (symbol_list): `guard' and `guard_line' are new
18395 (symbol_list_new): Adjust.
18396 (copy_action): action_line is the first line, not the last.
18397 (copy_guard): Just as for actions, store the `action' only, not
18398 the switch/case/break flesh.
18399 Don't parse the user action that might follow the guard, let...
18400 (readgram): do it, i.e., now, there can be an action after a
18402 In other words the guard is just explicitly optional.
18403 (packgram): Adjust.
18404 * src/output.c (guards_output): New.
18405 (output_parser): Call it when needed.
18406 (output): Also free the guard and attrs obstacks.
18407 * src/files.c, src/files.h (obstack_save): Remove.
18408 (output_files): Remove.
18409 As a result, if one needs the former `.act' file, using an
18410 appropriate skeleton which requires actions and guards is now
18412 * src/main.c (main): Adjust.
18413 * tests/semantic.at: New.
18414 * tests/regression.at: Use `input.y' as input file name.
18415 Avoid 8+3 problems by requiring input.c when the test needs the
18418 2001-12-27 Akim Demaille <akim@epita.fr>
18420 * src/reader.c (symbol_list_new): Be sure to initialize all the
18423 2001-12-27 Akim Demaille <akim@epita.fr>
18425 All the hacks using a final pseudo state are now useless.
18427 * src/LR0.c (set_state_table): state_table holds exactly nstates.
18428 * src/lalr.c (nLA): New.
18429 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
18430 instead of lookaheadsp from the pseudo state (nstate + 1).
18432 2001-12-27 Akim Demaille <akim@epita.fr>
18434 * src/output.c (action_row, token_actions): Use a state_t instead
18435 of a integer, and nlookaheads instead of the following state's

18440 * src/conflicts.c (log_resolution, flush_shift)
18441 (resolve_sr_conflict, set_conflicts, solve_conflicts)
18442 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
18443 (conflicts_print, print_reductions): Use a state_t instead of an
18444 integer when referring to a state.
18445 As much as possible, depend upon nlookaheads, instead of the
18446 `lookaheadsp' member of the following state (since lookaheads of
18447 successive states are successive, the difference between state n + 1
18448 and n served as the number of lookaheads for state n).
18449 * src/lalr.c (add_lookback_edge): Likewise.
18450 * src/print.c (print_core, print_actions, print_state)
18451 (print_results): Likewise.
18452 * src/print_graph.c (print_core, print_actions, print_state)

18461 Add plenty of `static'.
18463 2001-12-27 Akim Demaille <akim@epita.fr>
18465 * src/output.c (prepare): Drop the muscle `ntbase' which
18466 duplicates ntokens.
18467 * src/bison.simple: Formatting/comment changes.
18468 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
18469 is an undocumented synonym.
18471 2001-12-22 Akim Demaille <akim@epita.fr>
18473 * src/output.c (output_table_data): Change the prototype to use
18474 `int' for array ranges: some invocations do pass an int, not a
18476 Reported by Wayne Green.
18478 2001-12-22 Akim Demaille <akim@epita.fr>
18480 Some actions of web2c.y are improperly triggered.
18481 Reported by Mike Castle.
18483 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
18484 * tests/regression.at (Web2c): Rename as...
18485 (Web2c Report): this.
18486 (Web2c Actions): New.
18488 2001-12-22 Akim Demaille <akim@epita.fr>
18490 Reductions in web2c.y are improperly reported.
18491 Reported by Mike Castle.
18493 * src/conflicts.c (print_reductions): Fix.
18494 * tests/regression.at (Web2c): New.
18496 2001-12-18 Akim Demaille <akim@epita.fr>
18498 Some host fail on `assert (!"foo")', which expands to
18499 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
18500 Reported by Nelson Beebee.
18502 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
18503 `#define it_succeeded 0' and `assert (it_succeeded)'.
18505 2001-12-17 Marc Autret <autret_m@epita.fr>
18507 * src/bison.simple: Don't hard code the skeleton line and filename.
18508 * src/output.c (output_parser): Rename 'line' as 'output_line'.
18509 New line counter 'skeleton_line' (skeleton-line muscle).
18511 2001-12-17 Paul Eggert <eggert@twinsun.com>
18513 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
18514 YYDEBUG must be defined to a nonzero value.
18516 * src/bison.simple (yytname): Do not assume that the user defines
18517 YYDEBUG to a properly parenthesized expression.
18519 2001-12-17 Akim Demaille <akim@epita.fr>
18521 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
18522 nlookaheads is a new member.
18524 * src/lalr.h (nlookaheads): Remove this orphan declaration.
18525 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
18528 2001-12-17 Akim Demaille <akim@epita.fr>
18530 * src/files.h, src/files.c (open_files, close_files): Remove.
18531 * src/main.c (main): Don't open/close files, nor invoke lex_free,
18533 * src/reader.c (reader): Do it.
18535 2001-12-17 Akim Demaille <akim@epita.fr>
18537 * src/conflicts.c (print_reductions): Formatting changes.
18539 2001-12-17 Akim Demaille <akim@epita.fr>

18545 2001-12-17 Akim Demaille <akim@epita.fr>
18547 * src/output.c (output_obstack): Be static and rename as...
18548 (format_obstack): this, to avoid any confusion with files.c's
18550 * src/reader.h (muscle_obstack): Move to...
18551 * src/output.h: here, since it's defined in output.c.
18553 2001-12-17 Akim Demaille <akim@epita.fr>
18555 * src/output.c (action_row, save_column, default_goto)
18556 (sort_actions, matching_state, pack_vector): Better variable
18559 2001-12-17 Akim Demaille <akim@epita.fr>
18561 * src/output.c: Various formatting changes.
18563 2001-12-17 Akim Demaille <akim@epita.fr>
18565 * src/files.c (output_files): Free the output_obstack.
18566 * src/main.c (main): Call print and print_graph conditionally.
18567 * src/print.c (print): Work unconditionally.
18568 * src/print_graph.c (print_graph): Work unconditionally.
18569 * src/conflicts.c (log_resolution): Output only if verbose_flag.
18571 2001-12-16 Marc Autret <autret_m@epita.fr>
18573 * src/output.c (actions_output): Fix. When we use %no-lines,
18574 there is one less line per action.
18576 2001-12-16 Marc Autret <autret_m@epita.fr>
18578 * src/bison.simple: Remove a useless #line directive.
18579 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
18580 * src/output.c (get_lines_number): New.
18581 (output_parser): Adjust, now takes care about the lines of a
18583 Fix line numbering.
18584 (actions_output): Computes the number of lines taken by actions.
18585 (output_master_parser): Insert new skeleton which is the name of

18592 2001-12-15 Marc Autret <autret_m@epita.fr>
18594 * src/output.c (output_gram): Keep track of the hairy one.
18596 2001-12-15 Akim Demaille <akim@epita.fr>
18598 Make `make distcheck' work.
18600 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
18601 system.h which uses libgettext.h.
18603 2001-12-15 Akim Demaille <akim@epita.fr>
18605 * src/nullable.c (set_nullable): Useless rules must be skipped,
18606 otherwise, since we range over their symbols, we might look at a
18607 nonterminal which no longer ``exists'', i.e., it is not counted in
18608 `nvars', hence we overflow our arrays.
18610 2001-12-15 Akim Demaille <akim@epita.fr>
18612 The header can also be produced directly, without any obstack!
18615 * src/files.c, src/files.h (defines_obstack): Remove.
18616 (compute_header_macro): Global.
18617 (defines_obstack_save): Remove.
18618 * src/reader.c (parse_union_decl): No longer output to
18619 defines_obstack: its content can be found in the `stype' muscle
18621 (output_token_translations): Merge into...
18622 (symbols_output): this.
18624 (symbols_save): this.
18626 * src/output.c (header_output): New.
18629 2001-12-15 Akim Demaille <akim@epita.fr>
18631 * src/reader.c (parse_union_decl): Instead of handling two obstack
18632 simultaneously, use one to define the `stype' muscle, and use the
18633 value of the latter to fill defines_obstack.
18634 (copy_comment): Remove.
18635 (copy_comment2): Work for a single obstack.
18637 (copy_comment): this.
18639 2001-12-15 Akim Demaille <akim@epita.fr>
18641 * src/lex.c, src/lex.h (xgetc): No longer static.
18642 * src/reader.c (parse_union_decl): Revamp.
18644 2001-12-15 Akim Demaille <akim@epita.fr>
18646 Still making progress in separating Bison into (i) input, (ii)
18647 process, (iii) output: now we can directly output the parser file
18648 without using table_obstack at all.
18650 * src/files.c, src/files.h (table_obstack): Bye bye.
18651 (parser_file_name): New.
18652 * src/files.c (compute_output_file_names): Compute it.
18653 * src/output.c (actions_output, output_parser)
18654 (output_master_parser): To a file instead of an obstack.
18656 2001-12-15 Akim Demaille <akim@epita.fr>
18658 Attach actions to rules, instead of pre-outputting them to
18661 * src/gram.h (rule_t): action and action_line are new members.
18662 * src/reader.c (symbol_list): Likewise.
18663 (copy_action): Save the actions within the rule.
18664 (packgram): Save them in rule_table.
18665 * src/output.c (actions_output): New.
18666 (output_parser): Use it on `%%actions'.
18667 (output_rule_data): Don't free rule_table.
18669 (prepare): Don't save the `action' muscle.
18670 * src/bison.simple: s/%%action/%%actions/.
18672 2001-12-15 Akim Demaille <akim@epita.fr>
18674 * src/reader.c (copy_action): When --yacc, don't append a `;'
18675 to the user action: let it fail if lacking.
18676 Suggested by Arnold Robbins and Tom Tromey.
18678 2001-12-14 Akim Demaille <akim@epita.fr>
18680 * src/lex.c (literalchar): Simply return the char you decoded, non
18681 longer mess around with obstacks and int pointers.
18682 Adjust all callers.
18684 2001-12-14 Akim Demaille <akim@epita.fr>
18686 * src/lex.c (literalchar): Don't escape the special characters,
18687 just decode them, and keep them as char (before, eol was output as
18688 the 2 char string `\n' etc.).
18689 * src/output.c (output_rule_data): Use quotearg to output the
18692 2001-12-13 Paul Eggert <eggert@twinsun.com>
18694 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
18695 Do not infringe on the global user namespace when using C++.
18696 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
18697 All uses of `fprintf' and `stderr' changed.
18699 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
18701 2001-12-13 Akim Demaille <akim@epita.fr>
18703 The computation of nullable is broken: it doesn't handle empty
18706 * tests/torture.at (GNU AWK Grammar): New.
18707 * tests/sets.at (Nullable): New.
18708 * src/nullable.c (set_nullable): Instead of blindly looping over
18709 `ritems', loop over the rules, and then over their rhs's.
18711 Work around Autotest bugs.
18713 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
18714 frame, because Autotest understand lines starting with a `+' as
18715 traces from the shell. Then, they are not processed properly.
18716 Admittedly an Autotest bug, but we don't have time to wait for
18717 Autotest to catch up.
18718 * tests/regression.at (Broken Closure): Adjust to the new table
18721 * tests/sets.at: here.
18723 2001-12-13 Akim Demaille <akim@epita.fr>
18725 * src/closure.c (closure): Use nrules instead of playing tricks
18726 with BITS_PER_WORD.
18728 2001-12-13 Akim Demaille <akim@epita.fr>
18730 * src/print.c (print_actions): Output the handling of `$' as the
18731 traces do: shifting the token EOF. Before EOF was treated as a
18733 * tests/regression.at: Adjust some tests.
18734 * src/print_graph.c (print_core): Complete the set of items via
18735 closure. The next-to-final and final states are still unsatisfying,
18736 but that's to be addressed elsewhere.
18737 No longer output the rule numbers, but do output the state number.
18738 A single loop for the shifts + gotos is enough, but picked a
18739 distinct color for each.
18740 (print_graph): Initialize and finalize closure.
18742 2001-12-13 Akim Demaille <akim@epita.fr>
18744 * src/reader.c (readgram): Remove dead code, an strip useless
18746 (get_type): Remove, unused.
18748 2001-12-12 Akim Demaille <akim@epita.fr>
18750 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
18751 on that of lib/error.c.
18753 2001-12-12 Akim Demaille <akim@epita.fr>
18755 Some hosts don't like `/' in includes.
18757 * src/system.h: Include libgettext.h without qualifying the path.
18758 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
18761 2001-12-11 Marc Autret <autret_m@epita.fr>
18763 * src/output.c (output_parser): Remove useless muscle.
18765 2001-12-11 Marc Autret <autret_m@epita.fr>
18767 * src/bison.simple: Remove #line just before %%epilogue. It
18768 is now handled in ...
18769 * src/reader.c (read_additionnal_code): Add the output of a
18770 #line for the epilogue.
18772 2001-12-10 Marc Autret <autret_m@epita.fr>
18774 * src/reader.c (copy_definition): Re-use CPP-outed code which
18775 replace precedent remove.
18776 * src/bison.simple: Remove #line before %%prologue because
18777 %%input-line is wrong at this time.
18779 2001-12-10 Marc Autret <autret_m@epita.fr>
18781 * src/reader.c (symbols_output): Clean up.
18782 * src/output.c (output_gram, output): Clean up.
18784 2001-12-10 Akim Demaille <akim@epita.fr>
18786 * src/lalr.c (initialize_lookaheads): New. Extracted from...
18787 * src/LR0.c (set_state_table): here.
18788 * src/lalr.c (lalr): Call it.
18790 2001-12-10 Akim Demaille <akim@epita.fr>
18792 * src/state.h (shifts): Remove the `number' member: shifts are
18793 attached to state, hence no longer need to be labelled with a
18796 2001-12-10 Akim Demaille <akim@epita.fr>
18798 Now that states have a complete set of members, the linked list of
18799 shifts is useless: just fill directly the state's shifts member.
18801 * src/state.h (shifts): Remove the `next' member.
18802 * src/LR0.c (first_state, last_state): Remove.
18803 Adjust the callers.
18804 (augment_automaton): Don't look for the shifts that must be added
18805 a shift on EOF: it is those of the state we looked for! But now,
18806 since shifts are attached, it is no longer needed to looking
18807 merely by its id: its number.
18809 2001-12-10 Akim Demaille <akim@epita.fr>
18811 * src/LR0.c (augment_automaton): Better variable locality.
18812 Remove an impossible branch: if there is a state corresponding to
18813 the start symbol being shifted, then there is shift for the start
18814 symbol from the initial state.
18816 2001-12-10 Akim Demaille <akim@epita.fr>
18818 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
18819 only when appropriate: when insert_start_shifting_state' is not
18821 * tests/regression.at (Rule Line Numbers): Adjust.
18823 2001-12-10 Akim Demaille <akim@epita.fr>
18825 * src/LR0.c (augment_automaton): Now that all states have shifts,
18826 merge the two cases addition shifts to the initial state.
18828 2001-12-10 Akim Demaille <akim@epita.fr>
18830 * src/lalr.c (set_state_table): Move to...
18832 * src/lalr.c (lalr): Don't call it...
18833 * src/LR0.c (generate_states): do it.
18834 * src/LR0.h (first_state): Remove, only the table is used.
18836 2001-12-10 Akim Demaille <akim@epita.fr>
18838 * src/LR0.h (first_shift, first_reduction): Remove.
18839 * src/lalr.c: Don't use first_shift: find shifts through the
18842 2001-12-10 Akim Demaille <akim@epita.fr>
18844 * src/LR0.c: Attach shifts to states as soon as they are
18846 * src/lalr.c (set_state_table): Instead of assigning shifts to
18847 state, just assert that the mapping was properly done.
18849 2001-12-10 Akim Demaille <akim@epita.fr>
18851 * src/LR0.c (insert_start_shift): Rename as...
18852 (insert_start_shifting_state): this.
18853 (insert_eof_shifting_state, insert_accepting_state): New.
18854 (augment_automaton): Adjust.
18855 Better locality of the variables.
18856 When looking if the start_symbol is shifted from the initial
18857 state, using `while (... symbol != start_symbol ...)' sounds
18858 better than `while (... symbol < start_symbol ...)': If fail
18859 to see how the order between symbols could be relevant!
18861 2001-12-10 Akim Demaille <akim@epita.fr>
18863 * src/getargs.h: Don't declare `spec_name_prefix' and
18864 `spec_file_prefix', declared by src/files.h.
18865 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
18866 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
18867 * src/output.c (prepare): Adjust.
18868 * src/reader.c (symbols_output): Likewise.
18869 * src/vmsgetargs.c: Vaguely adjust, but who cares?
18871 2001-12-10 Akim Demaille <akim@epita.fr>
18873 * src/muscle_tab.c (muscle_init): NULL is a better default than
18876 2001-12-10 Akim Demaille <akim@epita.fr>
18878 * src/reader.c (reader): Calling symbols_output once is enough.
18880 2001-12-10 Akim Demaille <akim@epita.fr>
18882 Now that states have a complete set of members, the linked list of
18883 reductions is useless: just fill directly the state's reductions
18886 * src/state.h (struct reductions): Remove member `number' and
18888 * src/LR0.c (first_reduction, last_reduction): Remove.
18889 (save_reductions): Don't link the new reductions, store them in
18891 * src/lalr.c (set_state_table): No need to attach reductions to
18892 states, it's already done.
18893 * src/output.c (output_actions): No longer free the shifts, then
18894 the reductions, then the states: free all the states and their
18897 2001-12-10 Akim Demaille <akim@epita.fr>
18899 * src/options.c (OPTN, DRTV, BOTH): New.
18900 (option_table): Use them.
18902 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
18903 the job of system.h.
18904 * src/options.c: Don't include stdio.h and xalloc.h for the same
18907 2001-12-10 Akim Demaille <akim@epita.fr>
18909 * src/output.c (output, prepare): Make sure the values of the
18910 muscles `action' and `prologue' are 0-terminated.
18912 2001-12-10 Akim Demaille <akim@epita.fr>
18914 Clean up GCC warnings.
18916 * src/reader.c (copy_action): `buf' is not used.
18917 (parse_skel_decl): Be static.
18918 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
18919 * src/options.h (create_long_option_table): Have a real prototype.
18920 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
18921 (hash_delete_at): Return const void *.
18922 Adjust casts to preserve the const.
18924 2001-12-10 Akim Demaille <akim@epita.fr>
18926 * configure.in: Require 2.52g.
18927 M4 is not needed, but AUTOM4TE is.
18928 * m4/m4.m4: Remove.
18929 * tests/Makefile.am: Adjust.
18931 2001-12-10 Akim Demaille <akim@epita.fr>
18933 One structure for states is enough, even though theoretically
18934 there are LR(0) states and LALR(1) states.
18936 * src/lalr.h (state_t): Remove.
18937 (state_table): Be state_t **, not state_t *.
18938 * src/state.h (core, CORE_ALLOC): Rename as...
18939 (state_t, STATE_ALLOC): this.
18940 Add the LALR(1) members: shifts, reductions, errs.
18941 * src/LR0.c (state_table): Rename as...
18942 (state_hash): this, to avoid name clashes with the global
18944 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
18945 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
18947 2001-12-10 Akim Demaille <akim@epita.fr>
18949 Bison dumps core on bash.y.
18950 Reported by Pascal Bart.
18952 * src/warshall.c (bitmatrix_print): New.
18954 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
18955 j must be the outer loop.
18956 * tests/regression.at (Broken Closure): New.
18958 2001-12-05 Akim Demaille <akim@epita.fr>
18960 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
18962 Reported by Peter Hamorsky.
18964 2001-12-05 Akim Demaille <akim@epita.fr>
18966 * src/conflicts.c (err_table): Remove.
18967 (resolve_sr_conflict): Adjust.
18968 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
18970 (state_t.reductions, state_t.shifts): this.
18972 2001-12-05 Akim Demaille <akim@epita.fr>
18974 * src/reduce.c (reduce_grammar_tables): No longer disable the
18975 removal of useless rules via CPP but via `if (0)', so that the
18976 compiler still check the code is valid.
18977 For instance, it should have noticed `rline' no longer exists: use
18978 the `line' member of rule_t.
18979 * src/gram.c (dummy, rline): Remove, unused.
18981 2001-12-05 Akim Demaille <akim@epita.fr>
18983 * src/output.c (pack_vector): Use assert, not berror.
18984 * src/main.c (berror): Remove, unused.
18986 2001-12-05 Akim Demaille <akim@epita.fr>
18988 New experimental feature: if --verbose --trace output all the
18989 items of a state, not only its kernel.
18991 * src/print.c (print_core): If `trace_flag', then invoke closure
18992 before outputting the items of the state (print_core is no longer
18993 a correct name them).
18994 (print_results): Invoke new_closure/free_closure if needed.
18996 2001-12-05 Akim Demaille <akim@epita.fr>
18998 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
18999 * src/closure.c, src/closure.h (itemsetsize): Rename as...
19000 (nitemset): for consistency with the rest of the project.
19002 2001-12-05 Akim Demaille <akim@epita.fr>
19004 * src/closure.c (print_closure): Improve.
19005 (closure): Use it for printing input and output.
19007 2001-12-05 Akim Demaille <akim@epita.fr>
19009 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
19010 indexed by nonterminals.
19012 2001-12-05 Akim Demaille <akim@epita.fr>
19014 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
19016 * src/warshall.h: Remove accidental duplication of the content.
19018 2001-12-05 Akim Demaille <akim@epita.fr>

19028 * src/closure.c (set_firsts): De-obfuscate.
19030 2001-12-05 Akim Demaille <akim@epita.fr>
19032 * src/output.c (action_row): De-obfuscate
19033 using the good o' techniques: arrays not pointers, variable
19034 locality, BITISSET, RESETBIT etc.
19036 2001-12-05 Akim Demaille <akim@epita.fr>
19038 Pessimize the code to simplify it: from now on, all the states
19039 have a valid SHIFTS, which NSHIFTS is possibly 0.
19041 * src/LR0.c (shifts_new): Be global and move to..
19042 * src/state.c, src/state.h: here.
19043 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
19044 * src/print_graph: Adjust.
19046 2001-12-05 Akim Demaille <akim@epita.fr>
19048 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
19049 * src/conflicts.c: Use it.
19050 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
19051 incorrectly ``simplified''.
19053 2001-12-05 Akim Demaille <akim@epita.fr>
19055 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
19056 using the good o' techniques: arrays not pointers, variable
19057 locality, BITISSET, RESETBIT etc.
19059 2001-12-05 Akim Demaille <akim@epita.fr>
19061 * src/state.h (SHIFT_SYMBOL): New.
19062 * src/conflicts.c: Use it to deobfuscate.
19064 2001-12-05 Akim Demaille <akim@epita.fr>
19066 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
19067 (print_reductions): De-obfuscate using the good o' techniques:
19068 arrays not pointers, variable locality, BITISSET.
19070 2001-12-05 Akim Demaille <akim@epita.fr>
19072 * src/conflicts.c (print_reductions): Arrays, not pointers.
19075 2001-12-05 Akim Demaille <akim@epita.fr>
19077 * src/conflicts.c (print_reductions): Pessimize, but clarify.
19079 2001-12-05 Akim Demaille <akim@epita.fr>
19081 * src/conflicts.c (print_reductions): Improve variable locality.
19083 2001-12-05 Akim Demaille <akim@epita.fr>
19085 * src/conflicts.c (print_reductions): Pessimize, but clarify.
19087 2001-12-05 Akim Demaille <akim@epita.fr>
19089 * src/conflicts.c (print_reductions): Improve variable locality.
19091 2001-12-05 Akim Demaille <akim@epita.fr>
19093 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
19094 * src/lalr.c: Use them.
19096 2001-12-05 Akim Demaille <akim@epita.fr>
19098 * src/LR0.c (augment_automaton): Formatting changes.
19099 Better variable locality.
19101 2001-12-05 Akim Demaille <akim@epita.fr>
19103 * src/lalr.c (matrix_print): New.
19104 (transpose): Use it.
19105 Use arrays instead of pointers.
19107 2001-12-05 Akim Demaille <akim@epita.fr>
19109 * src/lalr.c (maxrhs): Move to...
19110 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
19111 * src/lalr.c (build_relations): Adjust.
19113 2001-12-05 Akim Demaille <akim@epita.fr>
19115 * src/lalr.c (transpose): Free the memory allocated to the
19116 argument, as it is replaced by the results by the unique caller.
19117 (build_relations): Merely invoke transpose: it handles the memory
19119 Improve variable locality.
19120 Avoid variables used as mere abbreviations.
19121 (compute_lookaheads): Use arrays instead of pointers.
19123 2001-12-05 Akim Demaille <akim@epita.fr>
19125 * src/lalr.c (initialize_F): Improve variable locality.
19126 Avoid variables used as mere abbreviations.
19128 2001-12-05 Akim Demaille <akim@epita.fr>
19130 * src/derives.c (print_derives): Display the ruleno.
19131 * src/lalr.c (initialize_F, transpose): Better variable locality
19132 to improve readability.
19133 Avoid variables used as mere abbreviations.
19135 2001-12-05 Akim Demaille <akim@epita.fr>
19137 * src/lalr.c (traverse): Use arrays instead of pointers.
19139 2001-12-05 Akim Demaille <akim@epita.fr>
19141 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
19142 the handling of squeue.
19143 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19145 2001-12-05 Akim Demaille <akim@epita.fr>
19147 Because useless nonterminals are now kept alive (instead of being
19148 `destroyed'), we now sometimes examine them, and store information
19149 related to them. Hence we need to know their number, and adjust
19150 memory allocations.
19152 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
19154 * src/LR0.c (allocate_itemsets): The memory allocated to
19155 `symbol_count' was used for two different purpose: once to count
19156 the number of occurrences of each symbol, and later reassigned to
19157 `shift_symbol', containing the symbol that can be shifted from a
19159 Deobfuscate, i.e., allocate, use and free `symbol_count' here
19161 (new_itemsets): Allocate `shift_symbol' here.
19162 (allocate_itemsets): symbol_count includes useless nonterminals.
19163 Make room for them.
19164 (free_storage): Use `free', not `XFREE', for pointers that cannot

19175 * src/gram.c, src/gram.h (ritem_print): New.
19176 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
19177 (This useless function was defined only to work around VMS linkers
19178 that can't handle compilation units with variables only).
19179 * src/reduce.c (dump_grammar): Use it to trace the construction of
19182 2001-12-04 Paul Eggert <eggert@twinsun.com>
19184 * src/bison.simple (union yyalloc): Change member names
19185 to be the same as the stack names.
19186 (yyparse): yyptr is now union yyalloc *, not char *.
19187 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
19188 and may generate better code on some machines.
19189 (yystpcpy): Use prototype if __STDC__ is defined, not just
19190 if __cplusplus is defined.
19192 2001-11-30 Akim Demaille <akim@epita.fr>
19194 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
19195 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU

19198 Include WARNING_CFLAGS here.
19199 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared

19213 2001-11-29 Paul Eggert <eggert@twinsun.com>
19215 Name space cleanup in generated parser.

19218 and their effect on the user name space.
19220 * src/bison.simple:
19221 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
19222 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
19223 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
19225 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
19226 on user names when possible.
19228 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
19229 Simplify test for whather <alloca.h> exists.
19231 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
19233 (<stdio.h>): Include if YYDEBUG.
19235 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
19236 ! defined (yyoverflow) && ! defined (yymemcpy).
19238 (yymemcpy, yyparse): Rename local variables as needed so that
19239 they all begin with 'yy'.
19241 (yystrlen, yystpcpy): New functions.
19243 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
19246 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
19247 instead of relying on string.h functions. Use YYSTACK_ALLOC
19248 and YYSTACK_FREE instead of malloc and free.

19252 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
19253 before their first uses.

19263 if body instead of `;' to pacify GCC's warnings.
19265 2001-11-30 Akim Demaille <akim@epita.fr>
19267 Instead of mapping the LHS of unused rules to -1, keep the LHS
19268 valid, but flag the rules as invalid.
19270 * src/gram.h (rule_t): `useful' is a new member.
19271 * src/print.c (print_grammar): Adjust.
19272 * src/derives.c (set_derives): Likewise.
19273 * src/reader.c (packgram, reduce_output): Likewise.

19301 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
19302 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
19304 (union yyalloc): New type.
19305 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
19306 an arbitrary restriction on hosts where size_t is wider than int.
19308 (yyparse): Don't dump core if alloca or malloc fails; instead, report
19309 a parser stack overflow. Allocate just one block of memory for all
19310 three stacks, instead of allocating three blocks; this typically is
19311 faster and reduces fragmentation.
19313 Do not limit the number of items in the stack to a value that fits
19314 in 'int', as this is an arbitrary limit on hosts with 64-bit
19315 size_t and 32-bit int.
19317 2001-11-29 Marc Autret <autret_m@epita.fr>
19319 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

21179 introduces a guaranteed SEGV for semantic parsers.

21233 Adjust dependencies.
21235 2000-12-19 Akim Demaille <akim@epita.fr>
21237 * src/files.c (strsuffix): New.
21238 (stringappend): Be just like strcat but allocate.
21239 (base_names): Eve out from open_files.

21245 2000-12-19 Akim Demaille <akim@epita.fr>

21281 2000-12-19 Akim Demaille <akim@epita.fr>
21283 * src/files.c (open_files): Yipee! We no longer need all the code
21284 looking for `/tmp' since we have no tmp file.
21286 2000-12-19 Akim Demaille <akim@epita.fr>
21288 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

21313 2000-11-17 Akim Demaille <akim@epita.fr>
21315 * lib/obstack.h: Formatting changes.
21316 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
21317 prevents type checking.
21318 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
21319 cast the value to (void *): assigning a `foo *' to a `void *'

21346 * acconfig.h: Remove, no longer used.
21348 2000-11-07 Akim Demaille <akim@epita.fr>
21350 * src: s/Copyright (C)/Copyright/g.
21352 2000-11-07 Akim Demaille <akim@epita.fr>
21354 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
21356 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.

21378 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
21379 s/PFILE1/BISON_HAIRY/.
21380 Adjust dependencies.
21382 2000-11-03 Akim Demaille <akim@epita.fr>
21384 For some reason, this was not applied.
21386 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
21387 `unlink': it's no longer used.
21389 2000-11-03 Akim Demaille <akim@epita.fr>
21391 * src/files.c (skeleton_find): New function, eved out of...

21396 Don't use `atexit'.
21398 * src/files.c (obstack_save): New function.
21399 (done): Rename as...
21400 (output_files): this.
21401 Use `obstack_save'.
21402 * src/main.c (main): Don't use `atexit' to register `done', since
21403 it no longer has to remove tmp files, just call `output_files'
21404 when there are no errors.
21406 2000-11-02 Akim Demaille <akim@epita.fr>
21408 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
21409 `unlink': it's no longer used.
21410 * src/files.h: Formatting changes.
21412 2000-11-02 Akim Demaille <akim@epita.fr>
21414 Remove the last uses of mktemp and unlink/delete.
21416 * src/files.c (fdefines, ftable): Removed.
21417 (defines_ostack, table_obstack): New.

21453 * src/output.c (output_short_or_char_table): New function.
21454 (output_short_table, output_token_translations): Use it.

21474 2000-10-16 Akim Demaille <akim@epita.fr>
21476 * src/reader.c (copy_comment2): Expect the input stream to be on
21477 the `/' which is suspected to open a comment, instead of being
21478 called after `//' or `/*' was read.
21479 (copy_comment, copy_definition, parse_union_decl, copy_action)
21480 (copy_guard): Adjust.
21482 2000-10-16 Akim Demaille <akim@epita.fr>
21484 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
21485 `read_signed_integer'.
21487 2000-10-16 Akim Demaille <akim@epita.fr>
21489 * src/reader.c (copy_dollar): New function.
21490 (copy_guard, copy_action): Use it.

21496 New files, from Fileutils 4.0.27.
21497 * src/main.c (printable_version): Remove.

21504 2000-10-04 Akim Demaille <akim@epita.fr>

21508 2000-10-04 Akim Demaille <akim@epita.fr>
21510 When a literal string is used to define two different tokens,
21511 `bison -v' segfaults.
21512 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
21514 * tests/regression.m4: New file.
21515 Include the core of the sample provided by Piotr Gackiewicz.
21516 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
21519 2000-10-04 Akim Demaille <akim@epita.fr>
21521 * src/reader.c (parse_expect_decl): Keep `count' within the size
21525 2000-10-02 Paul Eggert <eggert@twinsun.com>

21533 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
21536 2000-10-02 Akim Demaille <akim@epita.fr>
21538 * src/derives.c, src/print.c, src/reduce.c: To ease the
21539 translation, move some `\n' out of the translated strings.
21541 2000-10-02 Akim Demaille <akim@epita.fr>
21543 The location tracking mechanism is precious for parse error
21544 messages. Nevertheless, it is enabled only when `@n' is used in
21545 the grammar, which is a different issue (you can use it in error
21546 message, but not in the grammar per se). Therefore, there should
21547 be another means to enable it.
21549 * src/getargs.c (getargs): Support `--locations'.
21550 (usage): Report it.
21551 * src/getargs.h (locationsflag): Export it.
21552 * src/lex.c (percent_table): Support `%locations'.
21553 * src/reader.c (yylsp_needed): Remove this variable, now replaced
21554 with `locationsflag'.
21555 * doc/bison.texinfo: Document `--locations' and `%locations'.
21557 * tests/calc.m4: Test it.
21559 For regularity of the names, replace each
21560 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
21561 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
21562 In addition replace each `flag' with `_flag'.
21564 2000-10-02 Akim Demaille <akim@epita.fr>
21566 Also test parse error messages, including with YYERROR_VERBOSE.
21568 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
21570 Use it to check the computations.
21571 Use it to check `nonassoc' is honored.
21572 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
21573 `--yyerror-verbose'.
21574 (_AT_CHECK_CALC): Adjust to this option.
21575 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
21577 2000-10-02 Akim Demaille <akim@epita.fr>
21579 Test also `--verbose', `--defines' and `--name-prefix'. Testing
21580 the latter demonstrates a flaw in the handling of non debugging
21581 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
21582 was used in order to simplify:
21598 unfortunately this leads to a CPP conflict when
21599 `--name-prefix=foo' is used since it produces `#define yydebug
21602 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
21603 (YYDPRINTF): New macro.
21605 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
21607 Also test `--verbose', `--defines' and `--name-prefix'.
21609 2000-10-02 Akim Demaille <akim@epita.fr>
21611 Improve the readability of the produced parsers.
21613 * src/bison.s1: Formatting changes.
21614 Improve the comment related to the `$' mark.
21615 (yydefault): Don't fall through to `yyresume': `goto' there.
21616 * src/output.c (output_parser): When the `$' is met, skip the end
21618 New variable, `number_of_dollar_signs', to check there's exactly
21619 one `$' in the parser skeleton.
21621 2000-10-02 Akim Demaille <akim@epita.fr>
21623 * lib/xstrdup.c: New file, from the fileutils.
21624 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
21625 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
21626 instead of strlen + xmalloc + strcpy.
21627 * src/symtab.c (copys): Remove, use xstrdup instead.
21629 2000-10-02 Akim Demaille <akim@epita.fr>
21631 * src/gram.h (associativity): New enum type which replaces the
21632 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
21633 `right_assoc', `left_assoc' and `non_assoc'.
21634 Adjust all dependencies.
21635 * src/reader.c: Formatting changes.
21636 (LTYPESTR): Don't define it, use it as a literal in
21637 `reader_output_yylsp'.
21638 * src/symtab.h (symbol_class): New enum type which replaces the
21639 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
21640 `sunknown', `stoken and `snterm'.
21642 2000-10-02 Akim Demaille <akim@epita.fr>
21644 * src/getargs.c (fixed_outfiles): Rename as...
21645 (yaccflag): for consistency and accuracy.
21646 Adjust dependencies.
21648 2000-10-02 Akim Demaille <akim@epita.fr>
21650 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21651 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21652 difficult and introduced a lot of core dump. It turns out that
21653 Bison used an implementation of `xmalloc' based on `calloc', and
21654 at various places it does depend upon the initialization to 0. I
21655 have not tried to isolate the pertinent places, and all the former
21656 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
21657 someone should address this issue.
21659 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
21660 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

21668 Various anti-`extern in *.c' changes.
21670 * src/system.h: Include `assert.h'.
21672 2000-10-02 Akim Demaille <akim@epita.fr>
21674 * src/state.h (nstates, final_state, first_state, first_shift)
21675 (first_reduction): Move their exportation from here...
21676 * src/LR0.h: to here.
21677 Adjust dependencies.
21678 * src/getargs.c (statisticsflag): New variable.
21679 Add support for `--statistics'.
21680 Adjust dependencies.
21682 Remove a lot of now useless `extern' statements in most files.
21684 2000-10-02 Akim Demaille <akim@epita.fr>
21686 * src/LR0.h: New file.
21689 2000-10-02 Akim Demaille <akim@epita.fr>

21715 * src/reduce.h: New file.
21716 Propagate its inclusion.
21717 * src/reduce.c: Topological sort and other formatting changes.
21718 (bool, TRUE, FALSE): Move their definition to...
21719 * src/system.h: here.
21721 2000-10-02 Akim Demaille <akim@epita.fr>
21723 * src/files.c: Formatting changes.
21724 (tryopen, tryclose, openfiles): Rename as...
21725 (xfopen, xfclose, open_files): this.
21726 (stringappend): static.
21727 * src/files.h: Complete the list of exported symbols.
21730 2000-10-02 Akim Demaille <akim@epita.fr>

21750 * src/lalr.c: Formatting changes, topological sorting etc.
21752 2000-10-02 Akim Demaille <akim@epita.fr>
21754 * src/output.c (token_actions): Introduce a temporary array,
21755 YYDEFACT, that makes it possible for this function to use
21756 output_short_table.
21758 2000-10-02 Akim Demaille <akim@epita.fr>
21760 `user_toknums' is output as a `short[]' in `output.c', while it is
21761 defined as a `int[]' in `reader.c'. For consistency with the
21762 other output tables, `user_toknums' is now defined as a table of
21765 * src/reader.c (user_toknums): Be a short table instead of an int
21767 Adjust dependencies.

22794 way to specify the flags -n, -l, and -r. Also added hooks for
