3 Undo most of the 2007-02-03 change, switching to the strcase module
4 now that gnulib strcase has been fixed.
5 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
6 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
7 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
8 * m4/.cvsignore: Add strcase.m4.
9 * src/getargs.c: Revert 2007-02-03 change, as follows.
10 Don't include c-strcase.h.
11 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
12 strcasecmp has "unspecified behavior" outside the POSIX locale,
13 but it works fine in practice if at least one argument is ASCII,
14 as is the case in Bison.

23
24 * data/lalr1.java (Stack): Work around old verifiers that disallow
25 access to the private fields of an inner class, from the outer class.
26 We can make Stack's fields public because user code doesn't have access
27 to the instance of Stack used by parse(). Reported by Paul Eggert.

31 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
32 the right spot for these files?
33 * bootstrap.conf (gnulib_modules): Add c-strcase.
34 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
35 c-strncasecmp.c.
36 * src/getargs.c: Include c-strcase.h.
37 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
38 to avoid unspecified behavior.

81 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
82 at_directive_argv arguments so these no longer have to be global
83 variables. Also, update the implementation for the following changes.
84 (fail_for_at_directive_too_many_args,
85 fail_for_at_directive_too_few_args): Add at_directive_name argument.
86 (at_directive_name): Remove as at_directive_argv[0] will be used for
87 this now.
88 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
89 for the directive name.
90 (at_directive_argc, at_directive_argv): Make these local within
91 skel_lex instead of global.

103 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
104 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
105 Summary" not "Directives".
106 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
107 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
108 since the former is now the more complete one.
109 (Prologue Alternatives): Likewise and do the same for %defines.
110 (Table of Symbols): Add summary of %code, add summary of %define, and
111 move full %code documentation to...
112 (Decl Summary): ... here for consistency with other entries in these
113 sections.
114 Move %define entry in order to keep this list alphabetized.
115 Reword %define entry a little to put less emphasis on the skeleton
116 concept, which most users shouldn't have to think about.

149 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
150 (Bison Options): Document in --skeleton entry.
151 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
152 full_skeleton can't necessarily hold all of pkgdatadir.
153 If the specified skeleton file name contains a `/', don't prepend
154 pkgdatadir.

202 Clean up %define and %code implementation in M4 some. Most
203 importantly, rename all related macros to be in the b4_percent_define
204 and b4_percent_code namespaces. Also, complete support for `.' in
205 %define variable names and %code qualifiers.
206 * data/bison.m4 (b4_check_user_names): Check for special
207 "SKELETON-NAMESPACE(name)" macros instead of using two nested
208 m4_foreach loops.
209 (b4_get_percent_define, b4_get_percent_code): Rename to...
210 (b4_percent_define_get, b4_percent_code_get): ... these.
211 Extend documentation with examples.
212 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
213 b4_percent_define_skeleton_variables and
214 b4_percent_code_skeleton_qualifiers.
215 Expect any value for the %define variable `foo' to be stored in the
216 macro named `b4_percent_define(foo)'; expect any %code blocks for the
217 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
218 expect any unqualified %code blocks to be stored in a macro named
219 `b4_percent_code_unqualified'.
220 Use m4_indir so that %define variable names and %code qualifiers can
221 contain `.', which is allowed by the grammar parser.
222 (b4_percent_define_default): New macro to set a default value for a
223 %define variable.
224 (m4_wrap): Update wrapped code, and fix some underquoting.
225 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
226 Expect grammar uses of %define variables and %code qualifiers to be
227 defined in b4_percent_define_user_variables and
228 b4_percent_code_user_qualifiers.
229 * data/c++.m4: Use b4_percent_define_default rather than
230 m4_define_default. Fix some underquoting. Skeleton usage of %define
231 variable define_location_comparison now implies skeleton usage of
232 %define variable filename_type.
233 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
234 data/push.c, data/yacc.c: Update macro names.

278 values to the empty string since these are no longer guaranteed
279 initialized by the front-end.
280 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
281 braces around b4_user_stype since this is no longer done by the
282 front-end.

284 post_prologue_obstack): Remove.

286 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
287 with digraphs. This fixes lex params and parse params.

294 obstacks.

341 Instead of having skeletons declare all valid %define variables and
342 %code qualifiers, provide macros that retrieve the associated values
343 and build these lists automatically. Thus Bison will now warn when a
344 variable or qualifier is not used by the skeleton in the current
345 invocation regardless of whether it might sometimes be used by that
346 skeleton in other invocations. Also, move all %define value macros to
347 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
348 form, which is replaced by %code.
349 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
350 (b4_check_user_names): ... this, and change the series of valid name
351 arguments to a single list argument for names used in the skeleton
352 similar to the existing list argument for names used in the grammar.
353 Warn instead of complaining.
354 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
355 values and %code code, to format %code code properly, and to build
356 lists of all %define variables and %code qualifiers used in the
357 skeleton: b4_skeleton_percent_define_variables and
358 b4_skeleton_percent_code_qualifiers.
359 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
360 Remove, and...
361 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
362 the skeleton names lists can finish building first. In place of
363 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
364 expect the lists b4_user_percent_define_variables and
365 b4_user_percent_code_qualifiers.

367 b4_location_type, b4_filename_type, b4_namespace, and
368 b4_define_location_comparison, update their names to the
369 b4_percent_define_ namespace.
370 * data/glr.c: Don't use b4_check_percent_define_variables and
371 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
372 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.

378 * data/yacc.c: Likewise, and don't call m4_exit in
379 b4_use_push_for_pull_if or m4_wrap code will never execute.
380 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
381 Rename to...
382 (muscle_grow_user_name_list): ... this for consistency with the
383 terminology used in bison.m4.
384 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
385 %define variable names, and rename muscle used_percent_define_variables
386 to user_percent_define_variables.
387 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
388 user_percent_code_qualifiers.
389 (content): Remove.
390 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
391 {CODE} form is no longer accepted.

405 variables using b4_check_percent_define_variables.

656 (code_props_plain_init, code_props_symbol_action_init,
657 code_props_rule_action_init, code_props_translate_code): The rest of
658 the new code_props functional interface. Among other things, the init
659 functions set the code_props kind field so that
660 code_props_translate_code will know whether to behave like
661 translate_symbol_action, translate_rule_action, or translate_code.
662 These old translate functions must remain until all other modules are

672 instead of rule.
673 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the

675 and printers.
676 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
677 (handle_action_dollar): Use symbol_list_n_get and set used flag
678 directly since symbol_list_n_used_set is removed.

682 Rewrite as wrappers around the new code_props interface.

810 Enable push parsers to operate in impure mode. Thus, %push-parser no
811 longer implies %pure-parser. The point of this change is to move
812 towards being able to test the push parser code by running the entire
813 test suite as if %push-parser had been declared.
814 * data/push.c (yypush_parse): For impure mode, remove the
815 yypushed_char, yypushed_val, and yypushed_loc arguments.
816 Instead, declare these as local variables initialized to the global
817 yychar, yylval, and yylloc.
818 For the first yypush_parse invocation only, restore the initial values
819 of these global variables when it's time to read a token since they
820 have been overwritten.
821 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
822 %push-parser.
823 * tests/calc.at (Simple LALR(1) Calculator): Always declare
824 %pure-parser along with %push-parser since this test case was designed

853 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
854 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
855 more closely mimic the pull parser logic.
856 Don't copy the pushed token to yychar, yylval, and yylloc until it's
857 time to read a token, which is after any initialization of yylval and

865 Rearrange initialization of the parser state variables so that the
866 skeleton doesn't have to have a copy for pull mode and another for push
867 mode. This patch also fixes at least a bug such that yylloc was not
868 initialized (with b4_location_initial_line and
869 b4_location_initial_column) upon calling yypush_parse. However, that
870 initialization now overwrites the first token's location;
871 %initial-action assigning @$ already did the same thing, and both bugs
872 will be fixed in a later patch.
873 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
874 (b4_declare_parser_state_variables): Remove initialization of yytoken,

879 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
880 yyps->NAME so it can be used in yypush_parse.
881 (yyparse or yypush_parse): For yypush_parse, don't print the
882 "Starting parse" diagnostic for invocations after the first.
883 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
884 yypush_parse, only do it for the first invocation.

1946 Require default %destructor/%printer to be declared using
1947 %symbol-default instead of an empty symbol list, and start working on
1948 new per-type %destructor/%printer. Discussed at
1949 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
1950 * NEWS (2.3+): Add %symbol-default to example.

1953 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
1954 (generic_symlist, generic_symlist_item): New nonterminals for creating
1955 a list in which each item is a symbol, semantic type, or
1956 %symbol-default.
1957 (grammar_declaration): Use generic_symlist in %destructor and %printer
1958 declarations instead of symbols.1 or an empty list.
1959 (symbol_declaration, precedence_declaration, symbols.1): Update actions
1960 for changes to symbol_list.

1964 * src/symlist.c, src/symlist.h: Extend such that a list node may
1965 represent a semantic type or a %symbol-default in addition to just an
1966 ordinary symbol. Add switched functions for setting %destructor's and
1967 %printer's.
1968 * tests/actions.at, tests/input.at: Add %symbol-default to all default

1973 Whether the default %destructor/%printer applies to a particular symbol
1974 isn't a question of whether the user *declares* that symbol (in %token,
1975 for example). It's a question of whether the user by any means
1976 *defines* the symbol at all (by simply using a char token, for
1977 example). $end is defined by Bison whereas any other token with token
1978 number 0 is defined by the user. The error token is always defined by
1979 Bison regardless of whether the user declares it with %token, but we
1980 may one day let the user define error as a nonterminal instead.
1981 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
1982 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
1983 the meaning of "user-defined".
1984 * tests/actions.at (Default %printer and %destructor for user-declared
1985 end token): Rename to...
1986 (Default %printer and %destructor for user-defined end token): ...
1987 this.
1988
1989 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
1990 computation of whether to apply the default, don't maintain a list of
1991 every Bison-defined symbol. Instead, just check for a first character
1992 of '$', which a user symbol cannot have, and check for the error token.

1996 Don't apply the default %destructor or %printer to the error token,
1997 $undefined, or $accept. This change fits the general rule that the
1998 default %destructor and %printer are only for user-declared symbols,
1999 and it solves several difficulties that are described in the new test
2000 cases listed below.
2001 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
2002 * tests/actions.at (Default %printer and %destructor are not for error
2003 or $undefined, Default %printer and %destructor are not for $accept):

2012 declarations have been parsed. Skip midrules, which have dummy LHS
2013 nonterminals.

2020 Redo some of the previous commit: add back the ability to use
2021 non-aliased/undeclared string literals since it might be useful to
2022 those declaring %token-table.
2023 * src/reader.c (check_and_convert_grammar): Undo changes in previous
2024 commit: don't worry about complaints from symbols_pack.
2025 * src/symtab.c (symbol_new, symbol_class_set,
2026 symbol_check_alias_consistency): Undo changes in previous commit: count
2027 each string literal as a new symbol and token, assign it a symbol
2028 number, and don't complain about non-aliased string literals.
2029 (symbols_pack): Since symbol_make_alias still does not decrement symbol
2030 and token counts but does still set aliased tokens to the same number,
2031 symbol_pack_processor now leaves empty slots in the symbols array.
2032 Remove those slots.
2033 * tests/regression.at (Undeclared string literal): Remove test case
2034 added in previous commit since non-aliased string literals are allowed
2035 again.
2036 (Characters Escapes, Web2c Actions): Undo changes in previous commit:

2043 be used before its declaration.
2044 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
2045 symbols_pack complained.
2046 * src/symtab.c (symbol_new): Don't count a string literal as a new
2047 symbol.
2048 (symbol_class_set): Don't count a string literal as a new token, and
2049 don't assign it a symbol number since symbol_make_alias does that.
2050 (symbol_make_alias): It's not necessary to decrement the symbol and
2051 token counts anymore. Don't assume that an alias declaration occurs
2052 before any uses of the identifier or string, and thus don't assert that
2053 one of them has the highest symbol number so far.
2054 (symbol_check_alias_consistency): Complain if there's a string literal
2055 that wasn't declared as an alias.
2056 (symbols_pack): Bail if symbol_check_alias_consistency failed since
2057 symbol_pack asserts that every token has been assigned a symbol number
2058 although undeclared string literals have not.

2082 alias, check and set its alias's user token number instead of its own,
2083 which is set to indicate the alias. Previously, every occurrence of
2084 the character token in the grammar overwrote that alias indicator with

2097 Set XGETTEXT_OPTIONS to values that check for C format strings,
2098 so that translators are warned about them (this also helps
2099 prevent core dumps).

2101 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
2102 function, since it simplifies our code a bit.

2105 rather than -W, so we don't get bogus warnings about sign comparisons.
2106 Add -Wpointer-arith, since that warning is useful (it reports code
2107 that does not conform to C89 and that some compilers reject).

2116 * src/scan-code.l: config.h and system.h are already #include'd by
2117 scan-code-c.c, so get rid of them here.

2499 warnings about types for $$, $n, @$, and @n can't be reported yet.

2501 all symbol declarations have been parsed.
2502 * src/scan-code.l (handle_action_dollar): Now that this is invoked
2503 after parsing the entire grammar file, the symbol list here in the case
2504 of a midrule is actually the midrule's empty RHS, so reference its
2505 parent rule's RHS where necessary.
2506 On the other hand, now that you can already know it's a midrule, you

2717 for supporting the old way, or for documenting the new way. I
2718 have modified 'bootstrap' to use screen scraping
2719 (in this case, HTML scraping). This is unreliable and inelegant,
2720 but I don't see any better way. Yuck.
2721 * bootstrap (TP_URL, WGET_COMMAND): New vars.
2722 (get_translations): New function, which uses HTML scraping to
2723 deduce locations of latest translations.
2724 Use this function to grab both bison and bison-runtime .po files.
2725 Don't bother priming the pump for the runtime-po domain any more,
2726 as it's now translated better than bison is.

4727 Instead, reallocate buffers twice as big each time, so that

5052 * src/output.c: Include scan-skel.h.
5053 (scan_skel): Remove decl, since scan-skel.h does this.
5054 (output_skeleton):
5055 Indent calls to "error" to pacify "make maintainer-distcheck".

5071 "make maintainer-distcheck" complained about.

5084 autogenerated by the maintainer.

5100 the new runtime-po domain, prime the pump by extracting the
5101 relevant strings from the obsolete translations. This code can be
5102 removed once the bison-runtime domain has been translated by each
5103 team.

5132 the 2005-04-17 change, which is now accomplished (mostly) via
5133 changes in the parsers as described above.

5139 Fix more problems reported by twlevo@xs4all.nl.
5140 * tests/cxx-type.at: Don't pipe output of ./types through sed to
5141 remove trailing spaces. This loses the exit status of ./types,
5142 and isn't needed since ./types shouldn't be emitting trailing
5143 spaces.
5144 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
5145 as the stack isn't valid in that case.
5146
5147 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
5148 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
5149 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):

5151 is used.

5158 overly-picky compilers that reject 'char *foo = "bar";'.
5159
5160 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
5161 to FILE * parameter, not to stderr. This fixes a typo introduced
5162 in the 2005-07-12 change.
5163
5164 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
5165 warnings from GCC 4.

5179 stack before failing, as the cleanup code will do it for us now.
5180 * data/lalr1.cc (yyerrlab): Likewise.
5181 * data/glr.c (yyparse): Pop everything off the stack before
5182 freeing it, so that destructors get called properly.
5183 * data/lalr1.cc (yyreturn): Likewise.
5184 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
5185 This is more consistent.

5189 Some English-language cleanups for %destructor.
5190 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

5199 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".

5202 Rename yyoverflowab to yyexhaustedlab.
5203 When memory exhaustion occurs during syntax-error reporting,
5204 report it separately rather than in a single diagnostic; this
5205 eases translation.

5215 msgids; there's little point to having them translated, since they
5216 can be understood only by someone who can read the
5217 (English-language) source code.
5218
5219 Generate runtime-po/bison-runtime.pot automatically, so that we
5220 don't have to worry about garbage getting in that file. We'll
5221 make sure after the next official release that old msgids don't
5222 get lost. See

5224
5225 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
5226 Now auto-generated.
5227 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
5228 Fix typos in explanations of the runtime file.
5229 * bootstrap: Change gettext keyword from YYI18N to YY_.
5230 Use standard Makefile.in.in in runtime-po, since we'll arrange
5231 for backward-compatible bison-runtime.po files in a different way.
5232 * data/glr.c (YY_): New macro, from yacc.c.
5233 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
5234 Translate messages intended for users.
5235 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
5236 the wording in the other skeletons. We don't know that the memory
5237 is virtual.
5238 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
5239 Use same method that yacc.c uses.
5240 Don't translate debugging messages.
5241 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
5242 it doesn't work (yet), and requires C++ expertise to fix.
5243 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
5244 Move defn to a more logical place, to be consistent with other
5245 skeletons.
5246 Don't translate debugging messages.
5247 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
5248 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
5249 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
5250 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

5273 if YYABORT is used).

5436 not GNU M4, and that it works with any POSIX-compatible Awk.
5437 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
5438 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
5439 so that we also get calc++-parser.yy. Geneate it.
5440 Use $(AWK), not gawk, since any conforming Awk will do.
5441 Put comment before action, since older 'make' can't handle comment
5442 in action.

5447 of target. (This had a shell syntax error anyway; a stray "x".)

5469 never had any % directives, we can simply pass it to yyerror.
5470 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
5471 be modified later, as that is the usual style in glr.c.

5480 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
5481 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
5482 so that we don't have to maintain their signatures.
5483 (yyFail): Check for buffer overflow, by using vsnprintf rather
5484 than vsprintf. Allocate a bigger buffer if possible.
5485 Report an error if buffer allocation fails.
5486 (yyStackOverflow): New function.
5487 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
5488 the initialization was successful. It might fail if storage was
5489 exhausted.
5490 (yyexpandGLRStack): Add more checks for storage allocation failure.
5491 Use yyStackOverflow to report failures.

5497 can print diagnostics on storage allocation failure. All callers
5498 changed.
5499 (yyresolveValue): Use yybool for boolean.
5500 (yyreportSyntaxError): Check for size-calculation overflow.
5501 This code is taken from yacc.c.

6046 Remove uses of 'short int' and 'unsigned short int'. This raises
6047 some arbitrary limits. It uses more memory but nowadays that's
6048 not much of an issue.
6049
6050 This change does not affect the generated parsers; that's a different
6051 task, as some users will want to conserve memory there.
6052
6053 Ideally we should use size_t to represent all object counts, and

6213 the normal case and one for the error case. Just use the
6214 first one uniformly. Problem reported by Frank Heckenbach.
6215 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
6216 use exactly the same macro in both places.
6217 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
6218 so that the normal-case YYRHSLOC works for the error case too.

6223 we have an array of locations. Use the same macro for both glr

6307 (build_relations): Initialize includes[i] in all cases.
6308 * src/reader.c (packgram): Always initialize rules[ruleno].prec
6309 and rules[ruleno].precsym. Initialize members in order.

6312 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.

6454 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
6455 whether the reducion was empty or not. This leaves room to
6456 improve the use of YYLLOC_DEFAULT in such a case.
6457 lalr1.cc is still experimental, so changing this is acceptable.
6458 And finally, there are probably not many users who changed the
6459 handling of locations in GLR, so changing is admissible too.
6460
6461 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
6462 empty reduction, set @$ to an empty location ending the previously

6606 macro, so that these directives are passed to
6607 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
6608 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
6609 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
6610 the extra Bison directives instead of the whole series.
6611 Change the grammar so that there are recoverable errors, and
6612 unrecoverable errors. Now we can have the parser give up before
6613 consuming the whole input. As a result we now can observe that
6614 the lookahead is freed when needed.
6615 Change the parser source to parse argv[1] instead of a hard coded
6616 string.
6617 Simplify yylex, and give a value and location to EOF.
6618 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
6619 passed directives already coded in the file.
6620 Add some tests to check the location of "error".
6621 For some tests, the C++ parser is correct, and not yacc.c.
6622 For other tests, they provide different, but unsatisfying, values,
6623 so keep the C++ value so that at least one parser is "correct"
6624 according to the test suite.
6625 (Actions after errors): Remove, this is subsumed by the
6626 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

6804 Spent a few hours checking out which prerequisite versions the

6806 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
6807 a seemingly endless set of combinations of versions more recent
6808 than that. The bottom line is that the current sources require
6809 fairly recent versions of the build tools, and it'll be some work

7076 test whether it can stand alone.
7077
7078 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
7079 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
7080 unused declaration.
7081
7082 * tests/synclines.at (%union synch line): Put a dummy member in

7326 When reducing initial empty rules, Bison parser read an initial
7327 location that is not defined. This results in garbage, and that

7376 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
7377 (yyerrlab1): Remove, but where it used to be (now the bottom part of
7378 yyerrlab), when hitting EOF, pop the whole stack here instead of
7379 merely falling thru the default error handling mechanism.
7380 (yyerrorlab): New label, with the old contents of YYERROR,
7381 plus the following change: pop the stack of rhs corresponding
7382 to the production that invoked YYERROR. That is how Yacc
7383 behaves (required by POSIX).

7625 The problem was that GLR parsers did not conform to the C standard,
7626 because actions like { $1 = $2 + $3; } expanded to expressions
7627 that invoked YYFILL in separate subexpressions, and YYFILL assigned
7628 to a local variable. The C standard says that expressions
7629 like (var = f ()) + (var = f ()) have undefined behavior.
7630 Another problem was that GCC sometimes issues warnings that
7631 yyfill and its parameters are unused.
7632
7633 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
7634 as possibly unused.
7635 (yyfill): New function.
7636 (YYFILL): Use it.
7637 (yyuserAction): Change type of yynormal to bool, so that it matches
7638 the new yyfill signature. Mark it as possibly unused.

7641 Follow up on a bug I reported in February, where a Bison-generated
7642 parser can loop. Provide a test case and a fix for yacc.c. I
7643 don't have a fix for lalr1.cc or for glr.c, unfortunately.
7644 The original bug report is in:

7647 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
7648 macro's size was becoming unwieldy.
7649 (yyerrlab): Do not discard an empty lookahead symbol, as this
7650 might destroy garbage.
7651 (yyerrorlab): New label, with the old contents of YYERROR,
7652 plus the following change: pop the stack of rhs corresponding
7653 to the production that invoked YYERROR. That is how Yacc
7654 behaves, and POSIX requires this behavior.
7655 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
7656 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
7657 Define 'alarm' to do nothing if unistd.h is not available.
7658 Add a new rule "exp: '-' error;" to test the above change to
7659 data/yacc.c. Use 'alarm' to abort any test taking longer than
7660 10 seconds, as it's probably looping.
7661 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
7662 Also, the new yacc.c generates two fewer diagnostics for an
7663 existing test.

8291 we don't need to worry about yyerrlab1 being reported as an

8312 free the last state, and then use the top state (the one we just
8313 popped). This means that the initial elements will not be freed
8314 explicitly, as is the case in yacc.c; it is not a problem, as
8315 these elements have fake values.

8428 'conflict_report'. Translate the entire conflict report at once,
8429 so that we don't assume that "," has the same interpretation in
8430 all languages.
8431 (conflicts_output): Use Yacc-style conflict report for each state,
8432 instead of our more-complicated style.
8433 (conflicts_print): Use Yacc-style conflict report, except print
8434 the input file name when not emulating Yacc.

8452 * data/yacc.c (yyparse): New local var yylerrsp, to record the
8453 top of the location stack's error locations.
8454 (yyerrlab): Set it. When discarding a token, push its location
8455 onto yylerrsp so that we don't lose track of the error's end.
8456 (yyerrlab1): Now is only the target of YYERROR, so that we can
8457 properly record the location of the action that failed. For GCC
8458 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
8459 GCC warning about yyerrlab1 being unused if YYERROR is unused.
8460 (yyerrlab2): New label, which yyerrlab now falls through to.
8461 Compute the error's location by applying YYLLOC_DEFAULT to

8524 If the user does not define YYSTYPE as a macro, Bison now declares it
8525 using typedef instead of defining it as a macro. POSIX requires this.
8526 For consistency, YYLTYPE is also declared instead of defined.
8527
8528 %union directives can now have a tag before the `{', e.g., the
8529 directive `%union foo {...}' now generates the C code
8530 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
8531 The default union tag is `YYSTYPE', for compatibility with Solaris 9
8532 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
8533 instead of `yyltype'.
8534
8535 `yystype' and `yyltype' are now obsolescent macros instead of being
8536 typedefs or tags; they are no longer documented and will be
8537 withdrawn in a future release.

8544 (yyltype, yystype): New (and obsolescent) macros,

8546 * data/yacc.c: Likewise.
8547
8548 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
8549 does not specify a union tag. This is for compatibility with
8550 Solaris 9 yacc.

8569 has (or usually has) an immediately-following braced code.

8571 to return when scanning braced code.

10319 Let nondeterministic skeletons be usable with deterministic
10320 tables.
10321
10322 With the patch, GAWK compiled by GCC without -O2 passes its test
10323 suite using a GLR parser driven by LALR tables. It fails with -O2
10324 because `struct stat' gives two different answers on my machine:
10325 88 (definition of an auto var) and later 96 (memset on this var).
10326 Hence the stack is badly corrumpted. The headers inclusion is to
10327 blame: if I move the awk.h inclusion before GLR's system header
10328 inclusion, the two struct stat have the same size.

10387 we can't expect the parser to be in lock-step sync with the scanner.

10446 properly for vectors of objects. Do not assume that adding a

10486 type enum_bitset_opts, to conform to the C Standard, and similarly
10487 for enum_bitset_type.

10490
10491 Do not use "struct bitset_struct" to mean different things in
10492 different modules. Not only is this confusing, it violates
10493 the C Standard, which requires that structure types in different
10494 modules must be compatible if one is to be passed to the other.
10495 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
10496 All instances of "struct bitset_struct *" replaced with "bitset".

10511 Do not call a function of type T using a call that assumes the
10512 function is of a different type U. Standard C requires that a
10513 function must be called with a type that is compatible with its
10514 definition.
10515 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
10516 New decls.

10900 to minimize the number of warnings from xgettext.
10901 (handle_action_dollar, handle_action_at): Don't use isdigit,

10903 outside the C locale.
10904
10905 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
10906 this is a GCC extension and is not portable to other compilers.

10909 Do not include <ctype.h>; no longer needed.

10911 warnings on OpenBSD 3.0).
10912

10914 it's not portable.
10915
10916 * tests/regression.at: Do not use 'cc -c input.c -o input';
10917 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
10918
10919 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
10920 exit status as failure, not just exit status 1. Sun C exits
10921 with status 2 sometimes.
10922

13506 BISON_HAIRY.

13508 specific values. Now it is m4 that performs the lookup.

13511 * src/output.c (actions_output, guards_output)
13512 (token_definitions_output): No longer keeps track of the output
13513 line number, hence remove the second argument.
13514 (guards_output): Check against the guard member of a rule, not the
13515 action member.
13516 Adjust callers.
13517 (output_skeleton): Don't look for the skeleton location, let m4 do
13518 that.
13519 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
13520 file will be used.
13521 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
13522 (prepare): Given that for the time being changesyntax is not
13523 usable in M4, rename the muscles using `-' to `_'.
13524 Define `defines_flag', `output_parser_name' and `output_header_name'.
13525 * src/output.h (actions_output, guards_output)
13526 (token_definitions_output): Adjust prototypes.
13527 * src/scan-skel.l: Instead of scanning the skeletons, it now
13528 processes the output of m4: `__oline__' and `#output'.
13529 * data/bison.simple: Adjust to be used by M4(sugar).
13530 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
13531 to date.
13532 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'

14102 these states are automatically computed from the initial state.
14103 (generate_states): Adjust.
14104 * src/print.c: When reporting a rule number to the user, substract

14111 0: `$axiom: START-SYMBOL $'.

14113 number of the states has changed (the final state is no longer
14114 necessarily the last), catch up.

14141 Be sure to preserve the value of the eoftoken.
14142 (reader): Make sure eoftoken is defined.
14143 Initialize nsyms to 0: now eoftoken is created just like the others.
14144 * src/print.c (print_grammar): Don't special case the eof token.
14145 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
14146 lie anyway, albeit pleasant.
14147 * tests/calc.at: Exercise error messages with eoftoken.
14148 Change the grammar so that empty input is invalid.

15153 faster and reduces fragmentation.

17423 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
17424 was used in order to simplify:
17425
17426 #if YYDEBUG
17427 if (yydebug)
17428 {
17429 ...
17430 }
17431 #endif
17432
17433 into
17434
17435 if (yydebug)
17436 {
17437 ...
17438 }
17439
17440 unfortunately this leads to a CPP conflict when
17441 `--name-prefix=foo' is used since it produces `#define yydebug
17442 foodebug'.
17443
17444 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.

17492 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
17493 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
17494 difficult and introduced a lot of core dump. It turns out that
17495 Bison used an implementation of `xmalloc' based on `calloc', and
17496 at various places it does depend upon the initialization to 0. I
17497 have not tried to isolate the pertinent places, and all the former
17498 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
17499 someone should address this issue.

17869 Change the handling of @s so that they behave exactly like $s.
17870 There is now a pseudo variable @$ (readble and writable), location
17871 of the lhs of the rule (by default ranging from the location of
17872 the first symbol of the rhs, to the location of the last symbol,
17873 or, if the rhs is empty, YYLLOC).
17874
17875 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
17876 yyval.
17877 (yyparse): When providing a default semantic action, provide a
17878 default location action.
17879 (after the $): No longer change `*YYLSP', just stack YYLOC the
17880 same way you stack YYVAL.
17881 * src/reader.c (read_declarations): Use warns.
17882 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
17883 (copy_action, case '@'): Likewise.

17908 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
17909 One `#if YYDEBUG' remains, since it uses variables which are
17910 defined only if `YYDEBUG != 0'.

18636 way to specify the flags -n, -l, and -r. Also added hooks for
