4 * data/yacc.c: Clean up M4 for readability, and make output
5 whitespace more consistent. For the main parse function
6 comment, instead of saying "yyparse or yypush_parse", say either
7 "yyparse" or "yypush_parse" depending on which it actually is.

11 Complain about unused %define variables and %code qualifiers.
12 * NEWS (2.5): Document.
13 * data/bison.m4 (b4_check_user_names): Complain instead of warn.
14 * doc/bison.texinfo (Decl Summary): Document complaint, and
15 improve %define documentation a little otherwise.
16 * tests/input.at (Reject unused %code qualifiers): Update.
17 (%define errors): Update.
18 (%define, --define, --force-define): Update.

23 2009-09-03 Joel E. Denny <jdenny@clemson.edu>
26 * src/output.c: Don't include assert.h.
27 (output_skeleton): Use aver not assert.

29 Paul Eggert's explanations in the mailing lists.
31 2009-09-05 Alex Rozenman <rozenman@gmail.com>
33 Use "Unresolved reference" error message when no symbols were found
34 in a symbolic reference resolution. Remove .expr and -expr from
35 the shown reference when the reference is unresolved.
36 * src/scan-code.l: Change the error message, adjust location columns,
37 rename variable "exact_mode" to "explicit_bracketing".

47 * bootstrap (find_tool): Improve error messages.
48 Fix typo about find_tool_names.
50 2009-08-29 Joel E. Denny <jdenny@clemson.edu>
52 Fix gcc 3.4.4 shadowing warning reported by Eric Blake.
54 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00093.html>.
55 * src/scan-code.h (code_props_rule_action_init): Rename
56 named_ref arg to name so it doesn't shadow named_ref type. This
57 makes it consistent with the function definition in scan-code.l
60 2009-08-28 Joel E. Denny <jdenny@clemson.edu>

97 Avoid compiler warning.
99 2009-08-27 Joel E. Denny <jdenny@clemson.edu>
101 tests: use perl for printing special sequences to files.
102 And skip tests if perl is not available. This is better than
103 playing tricks with shell portability. Suggested by Akim
105 * tests/input.at (Bad character literals): Use it here for
106 omitting final newlines.
107 (Bad escapes in literals): Use it here for special characters.
109 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
111 tests: show a use of %define lr.default-reductions "consistent"
112 * tests/conflicts.at (%nonassoc and eof): Extend to test that it
113 prevents the omission of expected tokens for %error-verbose.
115 2009-08-26 Akim Demaille <demaille@gostai.com>
117 tests: portability fix.
118 * tests/input.at (Bad escapes in literals): Don't expect "echo
119 '\0'" to output \ then 0.
121 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
123 Actually handle the yytable zero value correctly this time.
124 * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Don't
125 mention zero values in the YYTABLE comments.
126 * data/glr.c (yytable_value_is_error): Don't check for zero
128 * data/lalr1.cc (yy_table_value_is_error_): Likewise.
129 * data/yacc.c (yytable_value_is_error): Likewise.
130 * data/lalr1.java (yy_table_value_is_error_): Likewise.
131 (yysyntax_error): Fix typo in code: use yytable_ not yycheck_.
132 * src/tables.h: In header comments, explain why it's useless to
133 check for a zero value in yytable.
135 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
137 More fixes related to last two patches.
138 * data/c.m4 (b4_table_value_equals): Comment that YYID must be
140 * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Fix
141 yytable comments: zero indicates syntax error not default
143 * data/glr.c (yyis_pact_ninf): Rename to...
144 (yypact_value_is_default): ... this.
145 (yyisDefaultedState): Update for rename.
146 (yyis_table_ninf): Rename to...
147 (yytable_value_is_error): ... this, and check for value zero
148 besides just YYTABLE_NINF.
149 (yygetLRActions): Check for default value from yypact. It
150 appears that this check is always performed before this function
151 is invoked, and so adding the check here is probably redundant.
152 However, the code may evolve after this subtlety is forgotten.
153 Also, update for rename to yytable_value_is_error. Because that
154 macro now checks for zero, a different but equivalent branch of
155 the if-then-else here is evaluated.
156 (yyreportSyntaxError): Update for rename to
157 yytable_value_is_error. The zero condition was mishandled
159 (yyrecoverSyntaxError): Update for renames. No behavioral
161 * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_):
163 (yy_table_value_is_error_): New function.
164 (parse): Use new functions where possible. No behavioral
166 (yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_.
167 The zero condition was mishandled before.
168 * data/yacc.c (yyis_pact_ninf): Rename to...
169 (yypact_value_is_default): ... this.
170 (yyis_table_ninf): Rename to...
171 (yytable_value_is_error): ... this, and check for value zero
172 besides just YYTABLE_NINF.
173 (yysyntax_error): Update for rename to yytable_value_is_error.
174 The zero condition was mishandled before.
175 (yyparse): Update for renames. No behavioral changes.
176 * src/tables.h: Improve comments about yypact, yytable, etc.
177 more. Most importantly, say yytable value of zero means syntax
178 error not default action.
180 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
182 Fix %error-verbose for conflicts resolved by %nonassoc.
183 * NEWS (2.5): Document.

199 (yyis_table_ninf): Likewise.

202 Use it everywhere possible.
203 (yyis_table_ninf): Likewise.
204 (yysyntax_error): Improve internal comments.
205 * data/lalr1.cc (yysyntax_error_): Likewise.
206 * data/lalr1.java (yysyntax_error): Likewise.
207 * src/tables.h: Improve comments about yypact, yytable, etc.
209 2009-08-21 Joel E. Denny <jdenny@clemson.edu>
211 Use locale when quoting.
212 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER): Use
213 quote rather than implementing quoting here.
215 2009-08-20 Eric Blake <ebb9@byu.net>
217 Make previous patch more robust.
218 * src/output.c (ARRAY_CARDINALITY): New macro, copied from
220 (output_skeleton): Use it.
221 Suggested by Akim Demaille.
223 Import latest m4/m4.m4.
224 * submodules/autoconf: Update to autoconf 2.64.
225 * configure.ac (M4_GNU_OPTION): New define.
226 * src/output.c (output_skeleton): Use it to resolve FIXME.
227 * NEWS: Mention this.

231 Fix complaints about escape sequences.
232 Discussed starting at
233 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>.
234 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
235 For a \0 and similar escape sequences meaning the null
236 character, report an invalid escape sequence instead of an
237 invalid null character because the latter does not actually
238 appear in the user's input.
239 In all escape sequence complaints, don't escape the initial
240 backslash, and don't quote when the sequence appears at the end
241 of the complaint line unless there's whitespace that quotearg
243 Consistently say "invalid" not "unrecognized".
244 Consistently prefer "empty character literal" over "extra
245 characters in character literal" warning for invalid escape
246 sequences; that is, consistently discard those sequences.
247 * tests/input.at (Bad escapes in literals): New.
249 2009-08-19 Akim Demaille <demaille@gostai.com>
252 * doc/bison.texinfo: Fix minor Texinfo errors.
254 2009-08-19 Akim Demaille <demaille@gostai.com>
256 doc: %initial-action to initialize yylloc.
257 Reported by Bill Allombert.
258 * doc/bison.texinfo: Set fill-column to 76.
259 (Location Type): Document the use of %initial-action to initialize

277 * configure.ac: require gettext 0.17 to ensure compatibility with
280 2009-08-17 Akim Demaille <demaille@gostai.com>
282 build: lower gettext requirements.
284 Bison was uselessly requiring the formatstring macros from
285 gettext, which resulted in mo files not being installed on systems
286 that perfectly supported Bison mo files. Lower the requirement.
287 http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html
289 * configure.ac: Require need-ngettext instead of
290 need-formatstring-macros.
291 Reported by Martin Jabocs.
292 Suggested by Bruno Haible.
293 * INSTALL: Restructure.
294 (Internationalization): New.

314 that symbols_sorted hasn't been allocated yet.
315 (symbols_free): Free symbols_sorted.
316 (symbols_cmp, symbols_cmp_qsort): New functions.
317 (symbols_do): Sort symbol_table into symbols_sorted on first
319 * tests/input.at (Numbered tokens): Recombine tests now that the
320 output should be deterministic across multiple numbers.
322 2009-08-12 Akim Demaille <demaille@gostai.com>
326 * examples/calc++/Makefile.am: (EXTRA_DIST): Ship calc.stamp.

330 * tests/Makefile.am (TESTSUITE_AT): Add named-refs.at.
332 2009-08-10 Joel E. Denny <jdenny@clemson.edu>
334 Miscellaneous code readability improvements.
336 * src/reader.c (reader): Move %define front-end variable
337 defaults and checking into...
338 (prepare_percent_define_front_end_variables): ... this new
341 * src/scan-gram.l (INITIAL): For consistency with string
342 literals, don't store open quote on character literal. It's
343 discarded before returning anyway.
344 (SC_ESCAPED_CHARACTER): Similarly, don't store close quote.
345 Make length test more readable, and make the character stored
346 for an empty literal more obvious while consistent with the
349 * src/symtab.c, src/symtab.h: Rename USER_NUMBER_ALIAS to
350 USER_NUMBER_HAS_STRING_ALIAS throughout.
351 * src/symtab.c (symbol_make_alias): Remove comment from symtab.c
352 that is repeated in symtab.h. Improve argument names to make it
353 clear which side of the symbol-string alias pair is which.
354 (symbol_check_alias_consistency): Improve local variable names
355 for the same purpose.
356 * src/symtab.h (struct symbol): Make comments about aliases
358 (symbol_make_alias): Improve comments and argument name.
359 * src/output.c (token_definitions_output): Update for rename to
360 USER_NUMBER_HAS_STRING_ALIAS and improve comments about aliases.
362 2009-08-08 Alex Rozenman <rozenman@gmail.com>
364 Convert "misleading reference" messages to warnings.
365 * src/scan-code.l: New function 'show_sub_messages', more

384 maint: clean up update-b4-copyright code

427 Pacify "gcc -Wunused" for the input function from Flex.
428 Reported by Alex Rozenman. This warning shows up with gcc-4.3.0
430 * src/scan-code.l: Add "%option noinput", which I cannot find in
431 the Flex manual, but which Flex has supported since at least as
432 far back as 2.5.4. However, if any of our developers still use
433 Flex 2.5.4, they'll need to stop configuring with
434 --enable-gcc-warnings because "%option noinput" didn't work
435 correctly until Flex 2.5.6.

475 Some M4 cleanup in the testsuite.
476 Suggested by Eric Blake at
477 <http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00083.html>.
478 * tests/existing.at (_AT_TEST_EXISTING_GRAMMAR): Do not
479 complicate the code by distinguishing between a missing value
480 and an empty string value for an optional argument. This fix is
481 allowed by the similar fix in AT_TEST_TABLES_AND_PARSE below.
482 * tests/local.at (_AT_TEST_TABLES_AND_PARSE): Merge into...
483 (AT_TEST_TABLES_AND_PARSE): ... this now that the special
484 arguments are not needed because of the following changes.
486 Bison developers should use GNU M4 and should not use
487 POSIXLY_CORRECT when building the test suite, so do not
488 complicate the code by avoiding $10 and above.
489 Do not quote an empty string value for an optional argument, and
490 do not distinguish between a missing value and an empty string

532 Depend on it to create the sources of calc++ so that concurrent

534 Not only this is inefficient, this also builds incorrect sources
535 with several extractions mixed together.

588 symbols were read, by an iteration over the symbol table. This
589 traversal is nondeterministic, which can be a problem for test

676 Handle a trailing `:' in a user-supplied C++ namespace better.
677 * data/c++.m4 (b4_namespace_close): Don't let it be printed
678 among the closing braces here. This fix might make the
679 generated code easier to debug, but otherwise it should be
680 insignificant because a trailing `:' is a C++ error already.

684 remove useless variable.
685 * src/getargs.c (skeleton_arg): Remove now useless variable.

744 * etc/bench.pl.in (bench_grammar): Update use.
745 * src/files.c (tr): Move to...
746 * src/getargs.c, src/getargs.h (tr): ... here because I can't
747 think of a better place to expose it. My logic is that, for all
748 uses of tr so far, command-line arguments can be involved, and
749 getargs.h is already included.

872 * doc/bison.texinfo (Introduction): Likewise.
873 (Language and Grammar): Bison is no longer limited to LALR(1)

922 (compute_lookahead_tokens): Don't free goto_follows yet. Now
924 (initialize_LA): Export it. Move lookback allocation to...
925 (lalr): ... here because, for canonical LR, initialize_LA must
926 be invoked but lookback and much of the rest of LALR isn't
928 * main.c (main): Instead of lalr, invoke ielr, which invokes
930 * src/reader.c (reader): Default lr.type to "LALR".
931 Default lr.default_rules to "accepting" if lr.type is "canonical

1013 Fix portability issue in the test suite.
1014 * tests/local.at (AT_MATCHES_CHECK): New.
1015 Based on Perl instead of Sed. Sed has too many portability
1016 pitfalls, not ever Sed is GNU Sed.

1705 (m4_prepend): Remove, as it is unused and inherently quadratic,

1760 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not

1787 * NEWS (2.3b+): Rename to...
1788 (?.?): ... this because we're dropping the "+" version naming scheme,
1789 but, in general, we still can't be sure of our next release name.
1790 * bootstrap: Add a quick hack to remove from .gitignore the
1791 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
1792 entry. This should really be fixed in gnulib instead.
1793 * bootstrap.conf (gnulib_modules): Add gnumakefile.
1794 * configure.ac (AC_INIT): Set version name by invoking
1795 build-aux/git-version-gen.

1825 Fix some .gitignore and .cvsignore problems.
1826 * bootstrap (insert_sorted_if_absent): Replace all uses with...
1827 (insert_vc_ignore): ... this new function, which prepends `/' to all
1828 .gitignore entries before passing them to insert_sorted_if_absent.
1829 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
1830 .cvsignore files are maintained even though Bison developers run
1831 bootstrap while using Git.
1832 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
1835 * .gitignore (/*.patch *.log log patches applied): Remove, broken and
1836 unneeded. Reported by Eric Blake.

1851 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
1852 the first argument because it may become position-dependent, and unset
1853 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
1854 Add comments explaining these issues in more detail.
1856 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>
1858 Add .gitignore everywhere based on .cvsignore.

1889 2008-05-23 Joel E. Denny <jdenny@ces.clemson.edu>
1891 * HACKING: Don't say don't mention HACKING in the ChangeLog. We've

1893 (Test suite): Mention maintainer-push-check and maintainer-xml-check.
1894 (Release Procedure): Add FIXME about make alpha being unmaintained.

1912 2008-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
1914 * THANKS: Add Eric Blake.
1916 2008-04-23 Eric Blake <ebb9@byu.net>
1918 Revert prior patch, by working around autoconf regression.
1919 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
1920 ("Output file name: ("): Uncomment test.
1921 ("Output file name: )"): Likewise.
1922 Based on an idea from Noah Misch.
1924 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>

1938 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
1940 Update to the current gnulib CVS repository, and fix trigraph handling
1942 * bootstrap: Update gnulib CVS repository URL.
1943 (symlink_to_dir): Encapsulate the code that guarantees the destination
1944 directory exists into...
1945 (check_dst_dir): ... this new function, and...
1946 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
1947 fail when copying files into lib/uniwidth/.
1948 * src/output.c (prepare_symbols): When writing yytname muscles, where
1949 symbol names will be encoded in C-string literals, tell quotearg to
1950 escape trigraphs. This used to be the default in gnulib.
1951 * tests/regression.at (Token definitions): Because of the change in
1952 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
1953 escapes trigraphs in symbol names. Thus, yytname no longer has
1954 trigraphs unnecessarily doubly escaped. Update test case output.
1955 Extend test case to be sure Bison's own error messages will no longer
1956 have trigraphs in symbol names unnecessarily escaped once.
1958 2008-04-20 Joel E. Denny <jdenny@ces.clemson.edu>

1970 * NEWS (2.3a+): Mention that -g now takes an argument.
1971 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
1972 consistency. Update the -g and -x entries now that they take
1973 arguments. Use brackets to indicate optional arguments.
1974 * src/getargs.c (usage): Explain the relationship between arguments of
1975 long and short options more completely. Document --defines and -d
1976 separately since the former takes an argument but, for POSIX Yacc, the
1978 (short_options): Let -W take an optional argument like --warnings.

1993 -g and -x take optional arguments, just like their long options.

1996 Fix the handling of $opt which resulted in all the argument to be
1997 considered as optional.
1999 2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>

2005 (Bison Options): In the -L and --language entry, mention Java.

2034 <http://lists.gnu.org/archive/html/help-bison/2008-02/msg00023.html>.
2035 * data/yacc.c: Clean up whitespace in the output a little.
2036 (yypstate_allocated): Define for impure push parsers regardless of
2037 whether the pull interface is also requested.
2038 * tests/push.at (Push Parsing: Multiple impure instances): Extend to
2039 check impure push parsers without the pull interface.
2041 * data/yacc.c (yypstate_new): Don't try to invoke yyerror since
2042 yyerror takes arguments specified by %parse-param while yypstate_new

2635 (C++ Bison Interface): Mention `%define namespace' instead of
2637 (Table of Symbols): Remove the `%define push_pull' entry. The %define

2733 parsing requests here...
2734 * data/yacc.c: ... hack this to switch to push.c any time

2736 will go away when we mv push.c yacc.c.
2737 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
2738 push parsing is not supported since unused %define variables are

2949 Get rid of broken %no-parser, -n, and --no-parser implementation and
2951 * TODO: Don't mention them.
2952 * doc/bison.1: Likewise.
2953 * doc/bison.texinfo (Decl Summary): Likewise.
2954 (Bison Options): Likewise.
2955 (Option Cross Key): Likewise.
2956 * src/getargs.c (no_parser_flag): Remove global variable.
2957 (usage): Don't print description of -n and --no-parser.
2958 (long_options): Remove --no-parser entry here.
2959 (getargs): Remove -n case in the switch here.
2960 * src/getargs.h (no_parser_flag): Remove extern.
2961 * tests/regression.at (Web2c Actions): Remove comment that mentions
2964 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
2966 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
2967 name user variables starting with `yy'. Just pass NULL instead of a
2968 dummy local &yylval to yypush_parse.
2969 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
2972 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
2974 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
2975 true since it's then always used regardless of whether yyoverflow is
2976 defined. Reported by Christian Burger at
2977 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
2978 * THANKS: Add Christian Burger.
2980 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
2981 node names: say "Decl Summary" not "Bison Declaration Summary".
2983 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
2985 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
2986 determine whether this function has already complained about an invalid
2987 value for a %define boolean variable, don't check whether Bison has
2988 ever examined the value. As written, the check was a tautology.
2989 Instead, record and check for this complaint using a separate muscle.
2991 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
2993 Fix push parsing memory leak reported by Brandon Lucia at
2994 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
2995 * THANKS: Add Brandon Lucia.
2996 * data/push.c (yypstate_delete): Free the stack if it was reallocated
2997 but the parse never completed and thus freed it.
2998 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
2999 * tests/testsuite.at: Include push.at.
3000 * test/push.at: New.
3001 (Push Parsing: Memory Leak for Early Deletion): New test case.
3003 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
3005 Improve handling of multiple S/R conflicts in the same state and of S/R
3006 conflicts involving multiple reductions.
3007 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
3008 set for a state here or Bison will abort if it is reassigned on a
3009 later conflicted reduction in the same state.
3010 Similarly, don't finalize and assign the solved conflicts report here
3011 or it will be lost if it is reassigned on a later conflicted reduction
3013 (set_conflicts): Instead, assign them both here after all S/R conflicts
3014 in the state have been fully examined.
3015 * src/print.c (shift_set): Rename to...
3016 (no_reduce_set): ... this.
3017 (print_reductions): Update for rename, and add %nonassoc error action
3018 tokens to no_reduce_set so that, when printing the first remaining
3019 reduction on an error action token, the reduction is enclosed in
3021 (print_results): Update for rename.
3022 * tests/conflicts.at (Solved conflicts report for multiple reductions
3023 in a state): New test case.
3024 (%nonassoc error actions for multiple reductions in a state): New test
3027 * src/main.c (main): Don't depend on C99 features.
3029 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
3031 * build-aux/.cvsignore: Add compile.
3032 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
3035 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
3037 * bootstrap (slurp): Create target directories that don't exist.
3038 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
3040 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
3042 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
3044 * closure.c (closure): Likewise.
3045 * state.h (reductions): Comment sorting of rules.
3046 (state): Comment sorting of items.
3048 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
3050 Fix C++ test cases after recent Gnulib changes. Discussed starting at
3051 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
3052 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
3053 definition in order to avoid Gnulib headers since we don't use config.h
3055 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
3056 rather than AT_DATA so that config.h is included.
3058 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
3060 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
3061 instead of fprintf. Guard these functions with #if YYDEBUG instead of
3062 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
3063 and so that YYFPRINTF is guaranteed to be defined here.
3065 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
3067 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
3069 (muscle_percent_define_check_values): ... this more helpful function.
3070 Again, it's not used yet, but it will be.
3071 * src/muscle_tab.h: Likewise.
3073 Improve some comments in parser table construction.
3074 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
3075 (generate_states): Don't mention ruleset, which is internal to closure.
3076 * src/closure.c (closure): Explain sorting of core and itemset, which
3077 is required for this function to behave correctly.
3078 * src/closure.h (closure): Mention sorting.
3080 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
3082 * src/lalr.c (state_lookahead_tokens_count): For code readability,
3083 move the check for disabled transitions to an aver since conflict
3084 resolution hasn't happened yet.
3086 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3087 labels a state as inconsistent just because it has error transitions.
3088 The original form of this check appeared in revision 1.1 of lalr.c,
3089 which was committed on 1991-12-21. Now (at least), changing the
3090 consistency label on such a state appears to have no useful effect in
3091 any of the places it is examined, which I enumerate below. The key
3092 point to understanding each item in this enumeration is that a state
3093 with an error transition is labelled consistent in the first place only
3094 if it has no rules, so the check cannot matter for states that have
3095 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3096 to try to identify its conflicts, and a state must have *rules* to have
3097 conflicts. (2) Labelling a state as inconsistent will affect how
3098 action_row sets the default *rule* for the state. (3) Labelling a
3099 state as inconsistent will cause build_relations to add lookback edges
3100 to *rules* in that state.
3101 * src/state.h (struct state): Word the comment for member consistent
3104 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
3106 Don't depend on C99 features.
3107 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
3108 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
3109 * src/reader.c (check_and_convert_grammar): Fix for-loop.
3110 * src/state.c (state_mark_reachable_states): Fix for-loop.
3111 (state_remove_unreachable_states): Fix for-loop.
3113 Don't widen struct state with member reachable just to temporarily
3114 record reachability. Instead, use a local bitset.
3115 * src/state.h (struct state): Remove member.
3116 * src/state.c (state_new): Don't initialize it.
3117 (state_mark_reachable_states): Rename to...
3118 (state_record_reachable_states): ... this, and use bitset.
3119 (state_remove_unreachable_states): Use bitset.
3121 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
3123 * src/Makefile.am (yacc): Quote target action commands properly so
3124 that the yacc script isn't corrupt. Reported by Hans Aberg at
3125 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
3127 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
3128 the case of pure parsers. Reported by Frans Englich at
3129 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
3130 * THANKS: Add Frans Englich.
3132 * NEWS (2.3a+): In the %code entry, reference section `Bison
3133 Declaration Summary' from the manual now since the %code summary has
3135 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
3136 in the rules section must be terminated by semicolons.
3138 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
3140 Extend the front-end API for %define variables to more completely
3141 mirror the back-end. This will be useful in the future.
3142 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
3143 Update comments to mention the new front-end counterparts of these

3153 implementation more closely.
3154 (muscle_percent_define_invalid_value): New function.
3155 * src/muscle_tab.h (muscle_percent_define_get,
3156 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
3159 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
3161 * NEWS (2.3a+): Mention yesterday's state-removal change.
3162 (2.3a): Remove the %language entry, which was added after 2.3a.
3163 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
3164 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
3165 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
3166 tests/existing.at: Update copyright date.
3168 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
3170 If conflict resolution makes states unreachable, remove those states,
3171 report rules that are then unused, and don't report conflicts in those

3194 (new_itemsets, save_reductions): Update for rename to nitemset.
3195 * src/closure.c (nritemset): Rename to...
3196 (nitemset): ... this since the "r" appears to meaningless and isn't

3198 (closure): Update for rename.
3199 * src/closure.h (nritemset): Update extern to...
3200 (nitemset): ... this.

3325 * src/print.c (lookahead_set, state_default_rule): Remove.
3326 (print_reductions): Replace state_default_rule invocation with
3327 equivalent use of yydefact, which was computed in token_actions in
3329 (print_results): Don't allocate lookahead_set.
3331 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
3333 * data/lalr1.java: Prefix all private members with yy.
3335 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
3337 Use YYFPRINTF instead of fprintf where appropriate. Reported by
3338 Sebastien Fricker at
3339 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
3340 * THANKS: Add Sebastien Fricker.

3355 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
3357 Undo my 2007-02-07 change, switching back to the c-strcase module
3358 introduced in the 2007-02-03 change. Bruno Haible reported that
3359 the 2007-02-07 change would be dangerous in Turkish if we add a
3360 language whose name contains "i", since "i" is not lowercase "I"
3362 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
3363 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
3364 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.

3370 2007-02-11 Bruno Haible <bruno@clisp.org>
3372 Enable the Java related testsuite tests when the only Java compiler
3373 found is a gcj < 4.3. Discussed at
3374 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
3375 * configure.ac (gt_JAVACOMP): Don't specify a target_version.

3379 * data/Makefile.am: Update copyright date.
3380 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
3381 yypstate_new returns NULL.
3382 (yypstate_new): Return NULL if malloc does.
3383 * src/reader.c (packgram): Move translation of rule actions from the
3384 beginning of packgram to...
3385 (check_and_convert_grammar): ... here right before packgram is invoked
3386 so it's easier to write more complete comments, and remove redundant
3389 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
3391 As in semantic actions, make @$ in %initial-action, %destructor, and
3392 %printer imply %locations.
3393 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
3395 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
3396 (@$ in %initial-action implies %locations,
3397 @$ in %destructor implies %locations,
3398 @$ in %printer implies %locations): ... these new test cases.
3400 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
3402 Undo most of the 2007-02-03 change, switching to the strcase module
3403 now that gnulib strcase has been fixed.
3404 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
3405 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
3406 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
3407 * m4/.cvsignore: Add strcase.m4.
3408 * src/getargs.c: Revert 2007-02-03 change, as follows.
3409 Don't include c-strcase.h.
3410 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
3411 strcasecmp has "unspecified behavior" outside the POSIX locale,
3412 but it works fine in practice if at least one argument is ASCII,
3413 as is the case in Bison.
3415 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
3417 * tests/java.at: Skip tests if only one of javac/java is present.
3418 Reported by Joel E. Denny.
3419 * tests/atlocal.in: Adjust copyright years.
3421 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
3423 * data/lalr1.java (Stack): Work around old verifiers that disallow
3424 access to the private fields of an inner class, from the outer class.
3425 We can make Stack's fields public because user code doesn't have access
3426 to the instance of Stack used by parse(). Reported by Paul Eggert.
3428 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3430 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
3431 the right spot for these files?
3432 * bootstrap.conf (gnulib_modules): Add c-strcase.
3433 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
3435 * src/getargs.c: Include c-strcase.h.
3436 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
3437 to avoid unspecified behavior.
3439 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
3441 * doc/bison.texinfo (Decl Summary): Correct typo.
3443 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
3445 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
3446 Complain if the value does not match empty, "true" or "false".
3447 * data/c++.m4: Adjust default definitions of %define variables.
3448 * data/java.m4: Adjust default definitions of %define variables.
3449 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
3451 * tests/input.at (Boolean %define variables): Test new behavior.
3453 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
3455 * NEWS: Mention java.
3456 * TODO: Remove things that are done.
3457 * bootstrap.conf: Add javacomp-script and javaexec-script.
3458 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
3460 * data/Makefile.am: Add new files.
3461 * data/java-skel.m4: New.
3462 * data/java.m4: New.
3463 * data/lalr1.java: New.
3465 * doc/bison.texinfo: Put "A Complete C++ Example" under
3466 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
3467 under Other Languages.
3469 * src/getargs.c (valid_languages): Add Java.
3470 * src/getargs.h (struct bison_language): Update size of string fields.
3472 * tests/Makefile.am: Add java.at.
3473 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
3474 * tests/java.at: New.
3475 * tests/testsuite.at: Include it.
3477 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
3480 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
3481 at_directive_argv arguments so these no longer have to be global
3482 variables. Also, update the implementation for the following changes.
3483 (fail_for_at_directive_too_many_args,
3484 fail_for_at_directive_too_few_args): Add at_directive_name argument.
3485 (at_directive_name): Remove as at_directive_argv[0] will be used for
3487 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
3488 for the directive name.
3489 (at_directive_argc, at_directive_argv): Make these local within
3490 skel_lex instead of global.
3491 (INITIAL): Update directive start action for above changes.
3492 (SC_AT_DIRECTIVE_ARG): Rename to...
3493 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
3494 (SC_AT_DIRECTIVE_SKIP_WS): Update.
3495 (scan_skel): Move yylex_destroy to...
3496 (skel_scanner_free): ... here.
3497 * tests/skeletons.at (installed skeleton file name): Rename to...
3498 (installed skeleton file names): ... this.
3500 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
3502 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3503 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
3504 Summary" not "Directives".
3505 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
3506 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
3507 since the former is now the more complete one.
3508 (Prologue Alternatives): Likewise and do the same for %defines.
3509 (Table of Symbols): Add summary of %code, add summary of %define, and
3510 move full %code documentation to...
3511 (Decl Summary): ... here for consistency with other entries in these
3513 Move %define entry in order to keep this list alphabetized.
3514 Reword %define entry a little to put less emphasis on the skeleton
3515 concept, which most users shouldn't have to think about.
3517 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
3519 Adjust to recent gnulib changes.
3520 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
3521 Add string.h, string_.h, unistd_.h, wchar_.h.
3522 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
3523 * src/system.h: Don't include <stpcpy.h>; this is now done by
3526 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
3528 Simplify implementation of unqualified %code, implement macros for
3529 uniform treatment of boolean %define flags. Document %define.
3530 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
3531 b4_percent_code_ifdef): New.
3532 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
3533 * data/c++.m4: Define default value for global_tokens_and_yystype.
3534 * data/glr.cc: Likewise.
3535 * data/location.cc: Use b4_percent_define_flag_if.
3537 * doc/bison.texinfo (Decl Summary): Document %define.
3539 * src/parse-gram.y (Unqualified %code): Change muscle name to
3541 (content.opt): Default to empty.
3543 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
3545 Implement support for relative and absolute skeleton file names.
3546 Discussed starting at
3547 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
3548 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
3549 (Bison Options): Document in --skeleton entry.
3550 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
3551 full_skeleton can't necessarily hold all of pkgdatadir.
3552 If the specified skeleton file name contains a `/', don't prepend
3554 * src/parse-gram.y (prologue_declaration): If the specified skeleton
3555 file name contains a `/', prepend the grammar file directory.
3556 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
3557 * skeletons.at: New file.
3558 (relative skeleton file names): New test case.
3559 (installed skeleton file names): New test case.
3560 * tests/testsuite.at: Include skeletons.at.
3562 * bootstrap: Update copyright to 2007.
3564 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
3566 * bootstrap: Remove occurrences of .#bootmp from the files.
3568 2007-01-17 Akim Demaille <akim@epita.fr>
3570 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
3572 Use per-type %printer.
3574 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>

3584 2007-01-16 Akim Demaille <akim@epita.fr>
3586 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
3588 (Calc++ Scanner): Exit with failure if we can't open the input
3590 Accept "-" standing for stdin.
3591 (Calc++ Top Level): Print the result only if the parsing was
3594 2007-01-16 Akim Demaille <akim@epita.fr>
3596 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
3598 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
3599 and Joel E. Denny <jdenny@ces.clemson.edu>
3601 Clean up %define and %code implementation in M4 some. Most
3602 importantly, rename all related macros to be in the b4_percent_define
3603 and b4_percent_code namespaces. Also, complete support for `.' in
3604 %define variable names and %code qualifiers.
3605 * data/bison.m4 (b4_check_user_names): Check for special
3606 "SKELETON-NAMESPACE(name)" macros instead of using two nested
3608 (b4_get_percent_define, b4_get_percent_code): Rename to...
3609 (b4_percent_define_get, b4_percent_code_get): ... these.
3610 Extend documentation with examples.
3611 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
3612 b4_percent_define_skeleton_variables and
3613 b4_percent_code_skeleton_qualifiers.
3614 Expect any value for the %define variable `foo' to be stored in the
3615 macro named `b4_percent_define(foo)'; expect any %code blocks for the
3616 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
3617 expect any unqualified %code blocks to be stored in a macro named
3618 `b4_percent_code_unqualified'.
3619 Use m4_indir so that %define variable names and %code qualifiers can
3620 contain `.', which is allowed by the grammar parser.
3621 (b4_percent_define_default): New macro to set a default value for a
3623 (m4_wrap): Update wrapped code, and fix some underquoting.
3624 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
3625 Expect grammar uses of %define variables and %code qualifiers to be
3626 defined in b4_percent_define_user_variables and
3627 b4_percent_code_user_qualifiers.
3628 * data/c++.m4: Use b4_percent_define_default rather than
3629 m4_define_default. Fix some underquoting. Skeleton usage of %define
3630 variable define_location_comparison now implies skeleton usage of
3631 %define variable filename_type.
3632 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
3633 data/push.c, data/yacc.c: Update macro names.
3634 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
3637 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
3639 DJGPP specific issues.
3641 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
3642 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
3644 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3646 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
3647 run parsers in all tests so that Valgrind is invoked during
3648 maintainer-check-valgrind.
3649 (Duplicate representation of merged trees): Free all semantic values.
3650 (Duplicated user destructor for lookahead): Likewise.
3652 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3654 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
3655 command-line prefix.
3656 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
3657 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
3658 miss Valgrind messages.
3659 (Exploding the Stack Size with Malloc): Likewise.
3661 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3663 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
3664 locals. Reported by Juan Manuel Guerrero at
3665 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
3666 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
3667 Fix some indentation also.
3668 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
3669 explaining this issue.
3671 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
3672 and Joel E. Denny <jdenny@ces.clemson.edu>
3674 Simplify union and prologue handling, and escape union and lex/parse
3675 params with digraphs.
3676 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
3677 values to the empty string since these are no longer guaranteed
3678 initialized by the front-end.
3679 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
3680 braces around b4_user_stype since this is no longer done by the
3682 * src/files.c, src/files.h (pre_prologue_obstack,
3683 post_prologue_obstack): Remove.
3684 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
3685 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
3686 with digraphs. This fixes lex params and parse params.
3687 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
3688 * src/output.c (prepare): Remove muscle insertion of the prologues.
3689 (output): Remove freeing of pre_prologue_obstack and
3690 post_prologue_obstack.
3691 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
3692 than prologue_augment for prologue parsing so you don't need prologue
3694 (grammar_declaration): For %union RHS, use `braceless' instead of
3695 "{...}" so that braces are already stripped and code is escaped with
3697 * src/reader.c (prologue_augment): Remove.
3698 (reader): Remove initialization of pre_prologue_obstack and
3699 post_prologue_obstack.
3700 * src/reader.h (prologue_augment): Remove.
3702 * data/c.m4: Remove stray parenthesis.
3704 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3706 Remove quotes from variables names in %define directives and from
3707 qualifiers in %code directives, and restrict the characters that are
3708 allowed in them to M4-friendly ones. For %define, continue to support
3709 the quoted form as a deprecated feature. Discussed starting at
3710 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
3711 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
3713 * doc/bison.texinfo (Prologue Alternatives): Update.
3714 (Decl Summary): In %defines entry, update mention of `%code requires'
3715 and `%code provides'.
3716 (C++ Location Values): Update %define uses.
3717 (Calc++ Parser Interface): Likewise.
3718 (Calc++ Parser): Likewise, and update `%code requires' uses.
3719 (Table of Symbols): Update %code documentation.
3720 * src/parse-gram.y (prologue_declaration): For %define variables, use
3721 `variable' instead of `STRING'.
3722 (grammar_declaration): For %code qualifiers, use `ID' instead of
3724 (variable): New nonterminal that takes an `ID' or a `STRING'.
3725 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
3727 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
3728 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
3729 (%define errors): Update %define uses.
3731 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3733 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
3734 instead of muscle_insert for %define values so that M4-special
3735 characters are replaced with digraphs.
3736 * tests/input.at (%define errors): Extend to check weird values.
3738 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3740 Instead of having skeletons declare all valid %define variables and
3741 %code qualifiers, provide macros that retrieve the associated values
3742 and build these lists automatically. Thus Bison will now warn when a
3743 variable or qualifier is not used by the skeleton in the current
3744 invocation regardless of whether it might sometimes be used by that
3745 skeleton in other invocations. Also, move all %define value macros to
3746 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
3747 form, which is replaced by %code.
3748 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
3749 (b4_check_user_names): ... this, and change the series of valid name
3750 arguments to a single list argument for names used in the skeleton
3751 similar to the existing list argument for names used in the grammar.
3752 Warn instead of complaining.
3753 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
3754 values and %code code, to format %code code properly, and to build
3755 lists of all %define variables and %code qualifiers used in the
3756 skeleton: b4_skeleton_percent_define_variables and
3757 b4_skeleton_percent_code_qualifiers.
3758 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
3760 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
3761 the skeleton names lists can finish building first. In place of
3762 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
3763 expect the lists b4_user_percent_define_variables and
3764 b4_user_percent_code_qualifiers.
3765 * data/c++.m4: Where setting default values for b4_parser_class_name,
3766 b4_location_type, b4_filename_type, b4_namespace, and
3767 b4_define_location_comparison, update their names to the
3768 b4_percent_define_ namespace.
3769 * data/glr.c: Don't use b4_check_percent_define_variables and
3770 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
3771 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
3772 (b4_parser_class_name, b4_namespace): Define these using
3773 b4_get_percent_define for parser_class_name and namespace.
3774 * data/location.cc: Use b4_get_percent_define.
3775 * data/push.c: Don't use b4_check_percent_define_variables and
3776 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
3777 * data/yacc.c: Likewise, and don't call m4_exit in
3778 b4_use_push_for_pull_if or m4_wrap code will never execute.
3779 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
3781 (muscle_grow_user_name_list): ... this for consistency with the
3782 terminology used in bison.m4.
3783 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
3784 %define variable names, and rename muscle used_percent_define_variables
3785 to user_percent_define_variables.
3786 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
3787 user_percent_code_qualifiers.
3789 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
3790 {CODE} form is no longer accepted.
3791 * tests/input.at (Reject bad %code qualifiers): Rename to...
3792 (Reject unused %code qualifiers): ... this, and update test output.
3793 (%define error): Update test output.
3795 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
3797 Check for unrecognized %define variables similar to checking for
3798 unrecognized %code qualifiers. Check for redefined %define variables.
3799 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
3801 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
3802 (b4_check_percent_define_variables): New, also wraps it.
3803 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
3804 variables using b4_check_percent_define_variables.
3805 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
3806 all those exercised in the test suite and all those listed in the
3807 `Default values' section of c++.m4. Are there others?
3808 * data/push.c, data/yacc.c: Declare no valid %define variables.
3809 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
3810 similar to muscle_find, but it works even when the muscle stores a
3812 (muscle_grow_used_name_list): New function for constructing the used
3813 name list muscles that b4_check_for_unrecognized_names requires.
3814 * src/parse-gram.y (prologue_declaration): Warn if a variable is
3815 %define'd more than once. Define the b4_used_percent_define_variables
3816 muscle with muscle_grow_used_name_list.
3817 (grammar_declaration): Abbreviate %code code with
3818 muscle_grow_used_name_list.
3819 * tests/input.at (%define errors): New.
3821 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3823 Provide warn_at, complain_at, and fatal_at function callbacks to the
3824 skeletons, and use this for %code qualifier complaints.
3825 * data/bison.m4 (b4_error_at): New, invoked by...
3826 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
3827 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
3828 @fatal_at(...@) directives.
3829 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
3830 qualifiers in b4_used_percent_code_qualifiers and to use
3832 * src/location.c, src/location.h (boundary_set_from_string): New global
3834 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
3836 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
3837 to b4_used_percent_code_qualifiers.
3838 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
3840 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
3841 (lineno): Rename to...
3842 (out_lineno): ... this so I don't misunderstand it again.
3843 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
3844 here; these newlines are in the input but not the output file.
3845 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
3846 (at_directive_perform): ... this new static function, and add handling
3847 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
3849 * tests/input.at (Reject bad %code qualifiers): Update test output with
3850 locations and extend.
3852 * tests/output.at (Output file name: [, Output file name: ]): Remove
3853 bogus comment about these tests failing.
3855 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3857 Clean up b4_check_percent_code_qualifiers a little.
3858 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
3859 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
3860 documentation and add examples.
3861 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
3864 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
3866 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
3867 unreliable -- especially when they're hidden inside another macro.
3868 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
3869 data/c.m4: Remove m4_divert(-1).
3870 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
3871 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
3872 m4_divert_push(0) and m4_divert_pop(0).
3873 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
3874 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
3875 pushed and popped by m4sugar, should be first on the stack.
3877 Provide warn, complain, and fatal function callbacks to the skeletons.
3878 This provides more flexibility than m4_fatal, improves the error
3879 message format, and captures messages for translation. Discussed
3881 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
3882 * data/bison.m4 (b4_error): New, invoked by...
3883 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
3884 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
3885 directives. Because these M4 macros might be called when the current
3886 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
3887 the previous removal of uses of m4_divert, which caused trouble.
3888 (b4_check_percent_code_qualifiers): Use b4_complain instead of
3889 m4_fatal to report unrecognized %code qualifiers.
3890 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
3891 push parser requests.
3892 * data/glr.c: Use b4_complain instead of m4_fatal to report
3893 non-deterministic push parser requests.
3894 Update @output usage to @output(...@) form.
3895 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
3896 report missing %defines. Update @output usage to @output(...@) form.
3897 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
3899 * src/main.c (main): Invoke skel_scanner_free.
3900 * src/scan-skel.h (skel_scanner_free): Prototype new function.
3901 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
3902 obstack_for_string from flex-scanner.h.
3903 (YY_DECL): Use to declare skel_lex static.
3904 (decode_at_digraphs): Remove; now handled in the new
3905 SC_AT_DIRECTIVE_ARG start condition.
3906 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
3908 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
3909 at_directive_argv): New static globals.
3910 (INITIAL): Use fail_for_invalid_at.
3911 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
3912 recognize the start of a generalized `@directive(...@)' form and
3914 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
3915 directive args (using the new obstack_for_string), to decode the
3916 contained @ diagraphs, and to perform the directive. It recognizes
3917 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
3919 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
3920 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
3922 (scan_skel): Initialize obstack_for_string on the first call.
3923 (skel_scanner_free): New function to free obstack_for_string.
3924 * tests/input.at (Reject bad %code qualifiers): Update test output.
3926 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
3928 Consolidate the 4 prologue alternative directives (%code, %requires,
3929 %provides, and %code-top) into a single %code directive with an
3930 optional qualifier field. Discussed at
3931 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
3932 * NEWS (2.3a+): Rewrite the existing entry for the prologue
3934 * doc/bison.texinfo (Prologue Alternatives): Update.
3935 (Decl Summary): Update to %code "requires" and %code "provides".
3936 (Calc++ Parser): Update to %code "requires".
3937 (Table of Symbols): Remove entries for %requires, %provides, and
3938 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
3939 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
3940 are replaced by b4_percent_code_provides and b4_percent_code_requires,
3941 which are skeleton-specific.
3942 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
3943 declare what %code qualifiers it supports and to complain if any other
3944 qualifiers were used in the grammar.
3945 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
3946 and b4_user_code([b4_percent_code_provides]) in place of
3947 b4_user_requires and b4_user_provides.
3948 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
3949 Add b4_user_code([b4_percent_code_top]) and
3950 b4_user_code([b4_percent_code]).
3951 Invoke b4_check_percent_code_qualifiers.
3952 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
3953 PERCENT_REQUIRES): Remove.
3954 (grammar_declaration): Remove RHS's for %code-top, %provides, and
3955 %requires. Rewrite the %code RHS as the unqualified form defining the
3956 muscle b4_percent_code. Add another RHS for the qualified %code form,
3957 which defines muscles of the form b4_percent_code_QUALIFIER and the
3958 b4_used_percent_code_qualifiers muscle.
3959 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
3960 PERCENT_REQUIRES): Remove.
3961 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
3962 %code "requires" and %code "provides".
3963 * tests/input.at (Reject bad %code qualifiers): New.
3965 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
3967 Use the new code_props interface for destructors and printers.
3968 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
3969 printer_location members, and change the type of the destructor and
3970 printer members to code_props.
3971 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
3972 symbol_printer_get, semantic_type_destructor_set,
3973 semantic_type_printer_set, default_tagged_destructor_set,
3974 default_tagless_destructor_set, default_tagged_printer_set,
3975 default_tagless_printer_set): Use code_props in arguments and return
3976 types in place of char const * and location.
3977 (symbol_destructor_location_get, symbol_printer_location_get): Remove
3978 since the locations are now contained in the return of
3979 symbol_destructor_get and symbol_printer_get.
3980 * src/output.c (symbol_destructors_output, symbol_printers_output):
3982 (symbol_code_props_output): ... this to eliminate duplicate code.
3983 (output_skeleton): Update to use symbol_code_props_output.
3984 * src/reader.c (symbol_should_be_used): Update use of
3985 symbol_destructor_get.
3986 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
3987 Update uses of the various _destructor_set and _printer_set functions.
3988 * src/symtab.c: (default_tagged_destructor_location,
3989 default_tagless_destructor_location, default_tagged_printer_location,
3990 default_tagless_printer_location): Remove since we...
3991 (default_tagged_destructor, default_tagless_destructor,
3992 default_tagged_printer, default_tagless_printer): ... change the type
3993 of these to code_props.
3994 (symbol_new, semantic_type_new, symbol_destructor_set,
3995 semantic_type_destructor_set, symbol_destructor_get,
3996 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
3997 symbol_check_alias_consistency, default_tagged_destructor_set,
3998 default_tagless_destructor_set, default_tagged_printer_set,
3999 default_tagless_printer_set): Update.
4000 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
4001 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
4003 (symbol_print): Use SYMBOL_CODE_PRINT.
4005 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4007 Use the new code_props interface for rule actions.
4008 * src/symlist.h (symbol_list): Replace action, action_location, and
4009 used members with a code_props action_props member.
4010 * src/reader.c (symbol_should_be_used, grammar_rule_check,
4011 grammar_midrule_action, grammar_current_rule_merge_set,
4012 grammar_current_rule_symbol_append, packgram): Update.
4013 * src/scan-code.h (translate_rule_action): Remove, no longer used.
4014 * src/scan-code.l (handle_action_dollar): Update.
4015 (translate_rule_action): Remove, no longer used.
4016 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
4018 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4020 Use the new code_props interface in parse-gram.y.
4021 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
4022 Update all uses of translate_* functions to use the new code_props
4023 interface and to use gram_scanner_last_string_free and
4024 code_scanner_last_string_free where possible.
4025 (grammar_declaration): symbol_list_destructor_set and
4026 symbol_list_printer_set now perform the translation, so don't do it
4027 here. Use gram_scanner_last_string_free where possible.
4028 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
4029 translate_code): Remove, no longer used.
4030 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
4031 symbol_list_printer_set): Perform code translation here rather than
4032 depending on the caller to do so.
4034 * src/symlist.h (struct symbol_list): Correct some documentation typos.
4035 * src/scan-gram.h (gram_last_string): Remove declaration.
4036 * src/scan-gram.l (last_string): Declare it static.
4038 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4040 Encapsulate code properties and related functionality for the various
4041 destructors, printers, and actions into a code_props structure and
4042 interface. This patch merely implements code_props in scan-code.h and
4043 scan-code.l. Future patches will rewrite other modules to use it.
4044 Discussed starting at
4045 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
4046 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
4047 consistently initialize const structs that have an empty location
4049 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
4050 to ensure consistency.
4051 * src/scan-code.h (code_props): New structure.
4052 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
4053 function, macro, and const global variable for initializing a
4054 code_props with no code.
4055 (code_props_plain_init, code_props_symbol_action_init,
4056 code_props_rule_action_init, code_props_translate_code): The rest of
4057 the new code_props functional interface. Among other things, the init
4058 functions set the code_props kind field so that
4059 code_props_translate_code will know whether to behave like
4060 translate_symbol_action, translate_rule_action, or translate_code.
4061 These old translate functions must remain until all other modules are
4062 updated to use the new code_props interface.
4063 (code_scanner_last_string_free): New function similar to
4064 gram_scanner_last_string_free.
4065 (code_scanner_free): Add documentation.
4066 * src/scan-code.l: Implement the new interface.
4067 (code_lex): Make it static, add a code_props* argument, and remove the
4069 (last_string): New static global similar to the one in scan-gram.l.
4070 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
4072 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
4073 code_props since Bison may one day use this information for destructors
4075 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
4076 (handle_action_dollar): Use symbol_list_n_get and set used flag
4077 directly since symbol_list_n_used_set is removed.
4078 (translate_action): Add a code_props* argument and remove the rule,
4079 action, and location arguments. Pass the code_props* on to code_lex.
4080 (translate_rule_action, translate_symbol_action, translate_code):
4081 Rewrite as wrappers around the new code_props interface.
4082 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
4083 it would eventually need to break the encapsulation of code_props.
4085 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4087 * etc/.cvsignore: New.
4089 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4091 Add maintainer-push-check to run maintainer-check using push parsing in
4092 place of pull parsing where available.
4093 * Makefile.am (maintainer-push-check): New.
4094 * data/bison.m4 (b4_use_push_for_pull_if): New.
4095 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
4096 appropriately based on their existing values.
4097 (yypush_parse): Don't print push-parser-specific diagnostics if push
4098 parsing is being used in place of pull parsing.
4099 * data/yacc.c: If push parsing should replace pull parsing, redirect to
4101 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
4102 variable, and insert b4_use_push_for_pull_flag into muscles.
4103 * tests/Makefile.am (maintainer-push-check): New.
4105 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4107 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
4108 (whether successful or failed) so that yypush_parse can be invoked
4109 again to start a new parse using the same yypstate.
4110 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
4111 check multiple yypull_parse invocations on the same yypstate. For pull
4112 mode, extend to check multiple yyparse invocations.
4113 (Exploding the Stack Size with Alloca): Extend to try with
4115 (Exploding the Stack Size with Malloc): Likewise.
4117 * tests/calc.at (Simple LALR Calculator): Don't specify
4118 %skeleton "push.c" since %push-pull-parser implies that now.
4119 * tests/headers.at (export YYLTYPE): Don't check for the push
4120 declarations. Otherwise, this test case can't be used to see if push
4121 mode can truly emulate pull mode.
4122 * tests/input.at (Torturing the Scanner): Likewise.
4123 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
4124 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
4125 AT_YACC_IF, which now includes the case of push mode since %skeleton
4126 need not be used for push mode. This will be more intuitive once
4127 push.c is renamed to yacc.c.
4129 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4131 For push mode, convert yyparse from a macro to a function, invoke yylex
4132 instead of passing a yylexp argument to yypull_parse, and don't
4133 generate yypull_parse or yyparse unless %push-pull-parser is declared.
4134 Discussed starting at
4135 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
4136 * data/bison.m4 (b4_pull_if): New.
4137 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
4138 * data/push.c: Improve M4 quoting a little.
4139 (b4_generate_macro_args, b4_parenthesize): Remove.
4140 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
4141 any time a pull parser is requested.
4142 Don't #define this as a wrapper around yypull_parse. Instead, when
4143 both push and pull are requested, make it a function that does that
4145 (yypull_parse): If there's a b4_prefix, #define this to
4146 b4_prefix[pull_parse] when both push and pull are requested.
4147 Don't define this as a function unless both push and pull are
4149 Remove the yylexp argument and hard-code yylex invocation instead.
4150 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
4152 * src/getargs.c (pull_parser): New global initialized to true.
4153 * getargs.h (pull_parser): extern it.
4154 * src/output.c (prepare): Insert pull_flag muscle.
4155 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
4156 (prologue_declaration): Set both push_parser and pull_parser = true for
4157 %push-pull-parser. Set push_parser = true and pull_parser = false for
4159 * src/scan-gram.l: Don't accept %push_parser as an alternative to
4160 %push-parser since there's no backward-compatibility concern here.
4161 Scan %push-pull-parser.
4162 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
4163 instead of %push-parser.
4164 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
4165 prototype it in the module that calls yyparse.
4166 * tests/input.at (Torturing the Scanner): Likewise.
4167 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
4169 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
4171 Update etc/bench.pl. Optimize push mode a little (the yyn change
4172 deserves most of the credit).
4173 * Makefile.am (SUBDIRS): Add etc subdirectory.
4174 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
4175 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
4176 yytoken, yyval, and yyloc declarations to...
4177 (yyparse or yypush_parse): ... here to improve performance. For
4178 yypush_parse invocations after the first, be sure to assign yyn its old
4180 (yypstate_new): Don't bother initializing the yyresult field since the
4181 initial value isn't used.
4182 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
4183 remove the #define that, in push mode, set it to yyps->NAME.
4184 * etc/Makefile.am: New.
4185 * etc/bench.pl: Remove and build it instead from...
4186 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
4187 "tests/bison" from the build directory by default rather than just
4188 invoking "bison" from $PATH.
4189 (calc_grammar): Update push parser code: don't declare yylval globally,
4190 don't define yyparse_wrapper, and don't #define yyparse.
4191 (bench_grammar): Update to check all working combinations of yacc.c,
4192 push.c, impure, pure, pull, and push.
4194 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4196 For push mode, add pull wrappers around yypush_parse.
4197 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
4198 (yypull_parse): New function wrapping yypush_parse.
4199 (yyparse): New #define wrapping yypull_parse.
4200 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
4202 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
4203 prototype yylex in the module that calls yyparse, and don't prototype
4204 yyparse there. Otherwise, the yyparse expansion won't compile.
4205 * tests/input.at (Torturing the Scanner): Likewise.
4207 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4209 Enable push parsers to operate in impure mode. Thus, %push-parser no
4210 longer implies %pure-parser. The point of this change is to move
4211 towards being able to test the push parser code by running the entire
4212 test suite as if %push-parser had been declared.
4213 * data/push.c (yypush_parse): For impure mode, remove the
4214 yypushed_char, yypushed_val, and yypushed_loc arguments.
4215 Instead, declare these as local variables initialized to the global
4216 yychar, yylval, and yylloc.
4217 For the first yypush_parse invocation only, restore the initial values
4218 of these global variables when it's time to read a token since they
4219 have been overwritten.
4220 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
4222 * tests/calc.at (Simple LALR(1) Calculator): Always declare
4223 %pure-parser along with %push-parser since this test case was designed
4224 for pure push parsers.
4225 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
4226 (AT_YACC_OR_PUSH_IF): New.
4227 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
4228 add a note that it's still wrong for some cases (as it has been for a
4230 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
4231 %push-parser no longer implies %pure-parser.
4233 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4235 Remove some unnecessary differences between the pull parser code and
4236 the push parser code. This patch enables yynerrs in push mode.
4237 * data/push.c: Reformat M4 a little.
4238 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
4239 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
4240 because push mode is on. Instead, if pure mode is on, move yynerrs
4242 (b4_declare_parser_state_variables): ... here.
4243 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
4244 to yyps->NAME so it can be used in yypush_parse.
4245 (yypush_parse): Don't omit uses of yynerrs in push mode.
4247 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4249 Fix bug such that the first pushed token's value and location are
4250 sometimes overwritten (sometimes by %initial-action) before being used.
4251 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
4252 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
4253 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
4254 more closely mimic the pull parser logic.
4255 Don't copy the pushed token to yychar, yylval, and yylloc until it's
4256 time to read a token, which is after any initialization of yylval and
4258 (gottoken): Rename label to...
4259 (yyread_pushed_token): ... for clarity and to avoid infringing on the
4262 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4264 Rearrange initialization of the parser state variables so that the
4265 skeleton doesn't have to have a copy for pull mode and another for push
4266 mode. This patch also fixes at least a bug such that yylloc was not
4267 initialized (with b4_location_initial_line and
4268 b4_location_initial_column) upon calling yypush_parse. However, that
4269 initialization now overwrites the first token's location;
4270 %initial-action assigning @$ already did the same thing, and both bugs
4271 will be fixed in a later patch.
4272 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
4273 (b4_declare_parser_state_variables): Remove initialization of yytoken,
4274 yyss, yyvs, yyls, and yystacksize.
4275 (yypstate_new): Remove initialization of some yypstate fields: yystate,
4276 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
4278 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
4279 yyps->NAME so it can be used in yypush_parse.
4280 (yyparse or yypush_parse): For yypush_parse, don't print the
4281 "Starting parse" diagnostic for invocations after the first.
4282 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
4283 yypush_parse, only do it for the first invocation.
4284 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
4285 initialization to occur in yypush_parse but only on the first
4288 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4290 * data/push.c: Add CPP guards around push parser declarations in both
4291 the header and the code file.
4292 In the code file, move the push parser declarations to the same place
4293 they appear in the header file.
4294 Clean up the M4 some, especially the inconsistent underquoting in
4295 some b4_c_function_def and b4_c_function_decl uses.
4297 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4299 Encapsulate the push parser state variables into an M4 macro so the
4300 push skeleton doesn't have to list them again for pull mode's yyparse.
4301 For push mode, remove yypush_parse's local equivalents of these
4302 variables to eliminate unnecessary copying between the two sets at
4303 run-time. This patch also fixes at least a bug related to multiple
4304 %initial-action invocations in push mode.
4305 * data/push.c (b4_declare_parser_variables): Rename to...
4306 (b4_declare_scanner_communication_variables): ... this for clarity and
4308 (b4_declare_yyparse_variables): Remove and move its contents to the one
4309 spot where it was invoked.
4310 (b4_declare_parser_state_variables): New macro containing the parser
4311 state variables required by push mode.
4312 (struct yypstate): Replace all fields but yynew with
4313 b4_declare_parser_state_variables.
4314 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
4315 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
4316 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
4317 (yyparse or yypush_parse): For yyparse in pull mode, replace local
4318 parser state variable declarations with
4319 b4_declare_parser_state_variables.
4320 Don't initialize parser state variables when calling yypush_parse since
4321 yypstate_new already does that.
4322 Invoke the user's initial action only upon the first yypush_parse
4324 Remove all code that copies between the local parser state variables
4327 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4329 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
4330 prevent a name collision in a future patch where these names will
4331 sometimes be #define'd.
4332 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
4333 since it no longer has the same name as the existing argument.
4334 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
4336 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
4337 and Joel E. Denny <jdenny@ces.clemson.edu>
4339 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
4340 that the argument is case-insensitive, and there's no `=' here.
4341 For the %skeleton entry, mention that %language is better.
4342 (Bison Options): Likewise for --language and --skeleton. Move the
4343 --skeleton entry so that the `Tuning the parser' section is sorted
4344 alphabetically on long options.
4345 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
4346 %language directive in detail here; cross-reference the %language
4347 documentation instead.
4348 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
4349 `%require "2.3b"' so that the example is always up-to-date.
4350 (Table of Symbols): Add entries for %language and %skeleton.
4351 * examples/extexi (normalize): Instead of replacing every %require
4352 argument with the current Bison version, just substitute for
4353 `@value{VERSION}'. This guarantees that we're testing what actually
4354 appears in the documentation.
4355 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
4356 rather than `@VERSION@'.
4358 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4360 * NEWS: Reword the %language news a bit, and put it earlier.
4362 * src/getargs.c (skeleton_arg): Last arg is now location const *.
4363 Rewrite to simplify the logic.
4364 (language_argmatch): Likewise.
4365 (program_name): We now own this var.
4366 * src/getargs.h (struct bison_language): Use char[] rather than
4369 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
4371 * src/complain.c (program_name): Remove decl; no longer needed.
4372 * src/main.c (program_name): Remove; now belongs to getargs.
4374 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
4376 * NEWS: Document %language.
4378 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
4380 * data/c-skel.m4, data/c++-skel.m4: New files.
4381 * data/glr.c: Complain on push parsers.
4383 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
4385 (Decl Summary): Document %language and %skeleton.
4386 (Command line): Document -L.
4388 * examples/extexi: Rewrite %require directive.
4389 * examples/calc++/Makefile.am: Pass VERSION to extexi.
4391 * src/files.c (compute_exts_from_gc): Look in language structure
4393 (compute_file_name_parts): Check whether .tab should be added.
4394 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
4395 (language, skeleton_arg, language_argmatch): New.
4396 (long_options): Add --language.
4397 (getargs): Use skeleton_arg, add -L/--language.
4398 * src/getargs.h: Include location.h.
4399 (struct bison_language, language, skeleton_arg, language_argmatch): New.
4400 * src/output.c (prepare): Pick default skeleton from struct language.
4401 Don't dispatch C skeletons here.
4402 * src/parse-gram.y (PERCENT_LANGUAGE): New.
4403 (prologue_declaration): Add "%language" rule, use skeleton_arg.
4404 * src/scan-gram.l ("%language"): New rule.
4406 * tests/calc.at: Test %skeleton and %language.
4407 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
4408 (AT_GLR_IF): Look for %skeleton "glr.cc".
4409 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
4410 (AT_YACC_IF): Reject %language.
4412 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4414 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
4415 since it wasn't used; only the typedef name 'semantic_type' is needed.
4416 Also, omit trailing white space.
4418 * bootstrap: Sync from coreutils.
4419 (gnulib_extra_files): Add build-aux/announce.gen.
4420 (slurp): Adjust .gitignore files like .cvsignore files.
4421 * build-aux/announce-gen: Remove from CVS, since bootstrap
4424 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
4426 Make %push-parser imply %pure-parser. This fixes several bugs; see
4427 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
4428 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
4430 * data/push.c: Don't bother testing b4_push_if when deciding whether
4431 to expand b4_declare_parser_variables globally.
4432 (yypush_parse): Likewise in here.
4434 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
4435 (yy_reduce_print): Reformat M4 for readability.
4437 2006-12-15 Bob Rossi <bob@brasko.net>
4438 and Joel Denny <jdenny@ces.clemson.edu>
4440 * data/push.c (yypstate): Add typedef, and update all uses of
4441 struct yypstate to just yypstate.
4442 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
4444 2006-12-14 Bob Rossi <bob@brasko.net>
4446 * data/push.c (yypush_parse): Declare prototype regardless of
4449 2006-12-14 Bob Rossi <bob@brasko.net>
4451 * data/push.c (yyparse): Remove the prototype and the #define when in
4454 2006-12-13 Bob Rossi <bob@brasko.net>
4456 * data/push.c (yypstate_init): Rename to...
4457 (yypstate_new): ... this and use b4_c_function_def.
4458 (yypstate_delete): New.
4459 (yypush_parse): Change parameters yynval and yynlloc to be const.
4460 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
4461 yypstate_delete functions.
4463 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
4465 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
4466 strange test case titles. Reported by Bob Rossi.
4468 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
4470 * TODO: Add pointer to Sylvain Schmitz's work on static detection
4471 of potential ambiguities in GLR grammers.
4473 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
4475 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
4476 `bison ', use m4_index instead of m4_substr since chopping up a string
4477 containing M4-special characters causes problems here.
4479 Fix a couple of bugs related to special characters in user-specified
4480 file names, and make it easier for skeletons to compute output file
4481 names with the same file name prefix as Bison-computed output file
4483 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
4484 b4_parser_file_name and b4_spec_defines_file instead of
4485 @output_parser_name@ and @output_header_name@, which are now redundant.
4486 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
4487 b4_parser_file_name, b4_spec_defines_file, and the new
4488 @basename(FILENAME@) instead of @output_parser_name@ and
4489 @output_header_name@, which inappropriately escaped the file names as
4491 * src/files.c (all_but_ext): Remove static qualifier.
4492 (compute_output_file_names): Move `free (all_but_ext)' to...
4493 (output_file_names_free): ... here since all_but_ext is needed later.
4494 * src/files.h (all_but_ext): Extern.
4495 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
4496 exactly what MUSCLE_INSERT_STRING used to do.
4497 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
4498 characters are escaped properly.
4499 * src/output.c (prepare): Define muscle file_name_all_but_ext as
4501 For pkgdatadir muscle, maintain previous functionality by using
4502 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
4503 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
4504 digraphs would never be expanded. Hopefully no one has M4-special
4505 characters in his Bison installation path.
4506 * src/scan-skel.l: Don't parse @output_header_name@ and
4507 @output_parser_name@ anymore since they're now redundant.
4508 In @output, use decode_at_digraphs.
4509 Parse a new @basename command that invokes last_component.
4510 (decode_at_digraphs): New.
4511 (BASE_QPUTS): Remove unused.
4512 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
4513 (Output file name): New tests.
4515 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
4517 Warn about output files that are generated by the skeletons and that
4518 conflict with other output files.
4519 * data/glr.c: Don't generate the header file here when glr.cc does.
4520 * src/files.c (file_names, file_names_count): New static globals.
4521 (compute_output_file_names): Invoke output_file_name_check for files
4522 not generated by the skeletons and remove existing checks.
4523 (output_file_name_check): New function that warns about conflicting
4525 (output_file_names_free): Free file_names.
4526 * src/files.h (output_file_name_check): Declare.
4527 * src/scan-skel.l: Invoke output_file_name_check for files generated by
4529 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
4530 (Conflicting output files): New tests.
4532 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4534 * doc/bison.texinfo: Fix a couple of typos.
4536 2006-12-08 Bob Rossi <bob@brasko.net>
4538 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
4540 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
4542 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
4543 (yypush_parse): Rename yypvars argument to yyps and remove redundant
4545 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
4546 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
4548 2006-12-07 Bob Rossi <bob@brasko.net>
4549 and Joel Denny <jdenny@ces.clemson.edu>
4551 * data/push.c (yypvarsinit): Change return type from void* to struct
4552 yypvars*. No longer cast to void* on return.
4553 (struct yypvars): Remove yylen since it need not be remembered between
4554 yypushparse invocations.
4555 (yypushparse): Don't copy between yylen and pv->yylen.
4557 2006-12-05 Bob Rossi <bob@brasko.net>
4559 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
4560 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
4561 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
4562 (struct yypvars): Remove b4_declare_parser_variables.
4563 (yypvarsinit): Remove init code for removed variables.
4564 (global scope): Do not declare b4_declare_parser_variables if
4566 (yypushparse): Add b4_declare_parser_variables.
4567 Init new local variables, and remove init code for removed
4570 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
4571 and yyparse for other modes.
4572 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
4573 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
4574 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
4575 (AT_PURE_LEX_IF): True if pure or push parser.
4577 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>

4659 later. Reported by Paul Eggert in

4663 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
4664 (code_scanner_free): Instead of invoking
4665 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

4673 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
4674 has been called previously for the same key.
4675 (muscle_find): Return storage instead of value so that
4676 --enable-gcc-warnings doesn't produce warnings that the return discards
4677 const. aver that the value and storage are the same since storage
4678 could potentially be NULL when value is not.
4679 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
4682 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4684 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
4685 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
4686 us a slightly cleaner distribution, and also works.
4687 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
4690 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
4691 and Paul Eggert <eggert@cs.ucla.edu>
4693 Don't let Bison leak memory except when it complains.
4694 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
4695 (spec_defines_file, dir_prefix): Now char *, not const char *,
4696 since they are freed.
4697 * src/files.c: Likewise.
4698 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
4700 (tr): Now operates in-place. All uses changed.

4703 (compute_file_name_parts, compute_output_file_names): Don't store
4704 read-only data in variables that will be freed.
4705 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
4706 src_extension, and header_extension.
4707 (output_file_names_free): New public function to free
4708 spec_verbose_file, spec_graph_file, spec_defines_file,
4709 parser_file_name, and dir_prefix.
4710 * src/getargs.c (getargs): Don't store read-only data in variables that
4712 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
4713 (which previously existed but was unused), and quotearg_free.
4714 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
4715 * src/muscle_tab.c: Likewise.
4716 (muscle_entry): Make the value char const *,
4717 and add a new storage member that is char * and can be freed.
4718 (muscle_entry_free): New private function.
4719 (muscle_init): Use it instead of free.
4720 (muscle_insert, muscle_grow): Update and use new storage member.
4721 (muscle_code_grow): Free the string passed to muscle_grow
4722 since it's not needed anymore.
4723 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
4724 add a new `char *code' member.
4725 ("{...}"): Declare semantic type as code.
4726 * src/scan-code.h (translate_rule_action):
4727 (translate_symbol_action, translate_code, translate_action): Return
4728 `char const *' rather than `char *' since external code should not free
4730 * src/scan-code.l: Likewise.
4731 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
4732 which is "{...}" in the parser.
4733 * tests/Makefile.am (maintainer-check-valgrind): Set
4734 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
4736 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
4738 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
4739 expecting a non-zero exit status sets --leak-check=summary and
4740 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
4741 this case, and we don't want to hear about it.
4743 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4745 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
4746 instead of from the template, to simplify configuration a bit.

4762 declarations): Run tests with and without --warnings=midrule-values.
4764 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
4765 than LIST_FREE directly.
4767 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

4786 empty subargument list. For example: `bison --warnings= parser.y'.
4788 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
4790 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
4791 the parser header file so that gcc doesn't warn.
4793 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
4795 Split the default %destructor/%printer into two kinds: <*> and <!>.

4841 Don't apply the default %destructor/%printer to an unreferenced midrule
4843 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
4844 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
4845 like $@n instead of just @n so that the default %destructor/%printer
4846 logic doesn't see them as user-defined symbols.
4847 (symbol_is_dummy): Check for both forms of the name.
4848 * src/reader.c (packgram): Remove the `$' from each midrule symbol
4849 name for which the midrule value is referenced in any action.
4850 * tests/actions.at (Default %printer and %destructor for mid-rule

4858 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
4860 (packgram): Before invoking grammar_rule_check on any rule, make sure
4861 all actions have already been scanned in order to set `used' flags.
4862 Otherwise, checking that a midrule's $$ is set will not always work
4863 properly because the midrule check must forward-reference the midrule's

4875 to show how these directives may be viewed as code labels.
4877 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
4879 Similar to the recently removed %before-header, add %code-top as the
4880 alternative to the pre-prologue. Mentioned at

4947 Fix testsuite for ./configure --enable-gcc-warnings:
4948 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.

4985 * tests/local.at (AT_DATA_GRAMMAR_PROLOGUE):
4986 Include <config.h> unconditionally.
4988 * bootstrap: Sync from coreutils, as follows:
4990 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4992 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
4993 variable was sometimes used without being initialized. This
4994 messed up the installation of the INSTALL file in some cases.
4996 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4998 * bootstrap (usage, main program, symlink_to_gnulib): Add option
4999 --copy. Inspired by a suggestion from Bruno Haible.
5001 2006-10-03 Jim Meyering <jim@meyering.net>
5003 * bootstrap: Undo last change to this file, since now gnulib-tool
5004 sticks with the automake default in generating dependencies.
5006 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
5008 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

5099 Fix problems with translating English-language diagnostics.
5100 * bootstrap: Fix bug introduced in recent bootstrap changes, with

5115 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
5116 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
5118 2006-09-23 Jim Meyering <jim@meyering.net>
5120 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
5122 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5124 * bootstrap: Add support for --force.
5125 (usage): New function. Describe usage less tersely.
5126 (CVS_only_file): New var.
5128 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
5130 * data/push.c (YYPUSH_MORE): Make it an enum instead.
5131 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
5132 Adjust white space and comments to match GNU style better.
5134 2006-09-20 Bob Rossi <bob@brasko.net>
5136 * data/push.c (yyresult_get): Remove function.
5137 (YYPUSH_MORE): Add #define.
5138 (yypushparse): Modify return value.
5140 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5142 * stamp-h.in: Remove; no longer needed.
5143 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
5144 Remove config.h, config.hin, intl (no longer created).
5145 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
5148 Sync bootstrap from coreutils, as follows:
5150 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
5152 * bootstrap (symlink_to_gnulib): New function.
5153 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
5154 to copies-of-gnulib.
5155 (cp_mark_as_generated, slurp, gnulib_files):
5156 Avoid making a copy if it's the same as the old version.
5157 (gnulib_files): Add support for this variable (used by Bison).
5159 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5161 * src/getargs.c (usage): Rework to use conventions similar to
5162 coreutils, to make translation a bit easier and the code a bit
5163 smaller. Problem reported by Tim Van Holder.
5165 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
5167 Use some of gnulib's new modules, taken from coreutils.
5169 * bootstrap: Sync from coreutils, except add support for gnulib_files.
5170 * bootstrap.conf: New file.
5171 (gnulib_modules): Add configmake, inttypes, unistd.
5172 (XGETTEXT_OPTIONS): Add complain, complain_at,
5173 fatal, fatal_at, warn, warn_at, unexpected_end.
5174 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
5175 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
5177 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
5179 (GNULIB_AUTOCONF_SNIPPET): Remove.
5180 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
5182 * lib/.cvsignore: Add inttypes_.h.
5183 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
5184 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
5185 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
5186 no-longer-necessary initializations.
5187 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
5188 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
5189 use the unistd module.
5190 * src/system.h: Likewise.
5191 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
5192 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
5193 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
5194 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
5195 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
5196 * src/system.h: Include inttypes.h unconditionally, now that we
5197 use the inttypes module. Don't bother to include stdint.h, since
5198 inttypes.h now does that for us.
5199 (LOCALEDIR): Remove, now that we use the configmake module.
5200 * src/getargs.c: Include configmake.h.
5201 * src/main.c: Likewise.
5202 * src/output.c: Likewise.
5203 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
5204 not from $abs_top_builddir, since config.h moved.
5207 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
5208 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
5210 * src/parse-gram.y (symbol_declaration): Don't put statements
5211 before declarations; it's not portable to C89.
5212 * src/scan-code.l (handle_action_at): Likewise.
5214 * src/scan-code.l: Always initialize braces_level; the old code
5215 left it uninitialized and therefore had undefined behavior.
5217 Don't attempt to redefine 'assert', since it runs afoul of
5218 systems where standard headers (mistakenly) include <assert.h>.
5219 Instead, define and use our own alternative, called 'aver'.
5220 * src/reader.c: Don't include assert.h, since we no longer
5222 * src/scan-code.l: Likewise.
5223 * src/system.h (assert): Remove, replacing with....
5224 (aver): New function, taking a bool arg. All uses changed.
5225 * src/tables.c (pack_vector): Ensure that aver arg is bool,
5226 not merely an integer.
5228 2006-09-15 Bob Rossi <bob@brasko.net>
5230 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
5231 * data/c.m4 (YYPUSH): New.
5232 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
5233 * src/getargs.c (push_parser): New var.
5234 * src/getargs.h (push_parser): New declaration.
5235 * src/output.c (prepare): Add macro insertion of `push_flag'.
5236 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
5237 (prologue_declaration): Parse %push-parser.
5238 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
5239 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
5240 list of removed lines from the traces observed.
5241 (AT_CHECK_CALC_LALR): Added push parser tests.
5243 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
5245 * NEWS: Version 2.3a.
5246 * configure.ac (AC_INIT): Likewise.
5248 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
5249 "#define YYSTYPE int" that caused "make maintainer-check" to fail
5250 due to header ordering dependencies. I don't know why the #define
5253 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
5254 runtime cost when YYDEBUG is not defined, and so that some tests
5255 that used to fail now work. Problem and initial suggestion by
5257 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
5258 * data/glr.cc (b4_parser_class_name):
5259 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
5260 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
5261 (yydebug_) [YYDEBUG]: New member.
5262 (yycdebug_): Now defined only if YYDEBUG.
5263 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
5264 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
5265 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
5267 (debug_stream, set_debug_stream, debug_level, set_debug_level):
5268 Define only if YYDEBUG.
5269 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
5271 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
5272 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
5273 AT_CHECK_CALC_GLR_CC that are working now.
5275 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
5277 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
5278 We don't need them in glr.cc, and glr.c defines them.
5279 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
5280 assumes that defining it to anything is the same as defining
5281 it to 1. Problem reported by Paolo Bonzini.
5283 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
5285 * data/c.m4 (b4_null, b4_case): Define.
5286 * src/output.c (prepare_symbols): Use b4_null.
5287 (user_actions_output): Use b4_case.
5289 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
5291 * data/glr.c (b4_shared_declarations): Put start-header first,
5292 before any #includes that we generate, so that feature-test
5293 macros work. Problem reported by Michael Deutschmann in
5294 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
5295 * data/lalr1.cc: Likewise.
5296 * doc/bison.texinfo (Prologue): Document that feature-test macros
5297 should be defined before any Bison declarations.
5298 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
5299 that depend on location.hh after, not before, Bison decls, since
5300 we now include location.hh after the first user prologue.
5302 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
5303 Sander Brandenburg in
5304 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
5305 Also, fix minor white space and comment issues.
5306 (Prologue): Mention that it's better to define feature-test macros
5307 before Bison declarations. Problem reported by Michael Deutschmann.
5309 * README-cvs: Fix typo: "&" should be "&&". Problem reported
5311 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
5312 This adjusts to recent gnulib changes.
5314 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
5316 Finish implementation of per-type %destructor/%printer. Discussed
5318 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
5320 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
5321 * NEWS (2.3+): Add a description of this feature to the default
5322 %destructor/%printer description.
5323 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
5324 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
5325 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
5326 list node contains a semantic type.
5327 * src/symtab.c, src/symtab.h: Extend with a table that associates
5328 semantic types with their %destructor's and %printer's.
5329 (semantic_type_from_uniqstr, semantic_type_get,
5330 semantic_type_destructor_set, semantic_type_printer_set): New functions
5331 composing the public interface of that table.
5332 (symbol_destructor_get, symbol_destructor_location_get,
5333 symbol_printer_get, symbol_printer_location_get): If there's no
5334 per-symbol %destructor/%printer, look up the per-type before trying
5336 * tests/actions.at (Per-type %printer and %destructor): New test case.
5337 * tests/input.at (Default %printer and %destructor redeclared):
5338 Extend to check that multiple occurrences of %symbol-default in a
5339 single %destructor/%printer declaration is an error.
5340 (Per-type %printer and %destructor redeclared, Unused values with
5341 per-type %destructor): New test cases.
5343 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
5345 Require default %destructor/%printer to be declared using
5346 %symbol-default instead of an empty symbol list, and start working on
5347 new per-type %destructor/%printer. Discussed at
5348 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
5349 * NEWS (2.3+): Add %symbol-default to example.
5350 * bison.texinfo (Freeing Discarded Symbols): Likewise.
5351 (Table of Symbols): Add entry for %symbol-default.
5352 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
5353 (generic_symlist, generic_symlist_item): New nonterminals for creating
5354 a list in which each item is a symbol, semantic type, or
5356 (grammar_declaration): Use generic_symlist in %destructor and %printer
5357 declarations instead of symbols.1 or an empty list.
5358 (symbol_declaration, precedence_declaration, symbols.1): Update actions
5359 for changes to symbol_list.
5360 * src/reader.c: Update for changes to symbol_list.
5361 * src/scan-code.l: Likewise.
5362 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
5363 * src/symlist.c, src/symlist.h: Extend such that a list node may
5364 represent a semantic type or a %symbol-default in addition to just an
5365 ordinary symbol. Add switched functions for setting %destructor's and
5367 * tests/actions.at, tests/input.at: Add %symbol-default to all default
5368 %destructor/%printer declarations.
5370 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
5372 Whether the default %destructor/%printer applies to a particular symbol
5373 isn't a question of whether the user *declares* that symbol (in %token,
5374 for example). It's a question of whether the user by any means
5375 *defines* the symbol at all (by simply using a char token, for
5376 example). $end is defined by Bison whereas any other token with token
5377 number 0 is defined by the user. The error token is always defined by
5378 Bison regardless of whether the user declares it with %token, but we
5379 may one day let the user define error as a nonterminal instead.
5380 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
5381 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
5382 the meaning of "user-defined".
5383 * tests/actions.at (Default %printer and %destructor for user-declared
5384 end token): Rename to...
5385 (Default %printer and %destructor for user-defined end token): ...
5388 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
5389 computation of whether to apply the default, don't maintain a list of
5390 every Bison-defined symbol. Instead, just check for a first character
5391 of '$', which a user symbol cannot have, and check for the error token.
5393 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
5395 Don't apply the default %destructor or %printer to the error token,
5396 $undefined, or $accept. This change fits the general rule that the
5397 default %destructor and %printer are only for user-declared symbols,
5398 and it solves several difficulties that are described in the new test
5400 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
5401 * tests/actions.at (Default %printer and %destructor are not for error
5402 or $undefined, Default %printer and %destructor are not for $accept):
5405 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
5407 Allow %start after the first rule.
5408 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
5409 when parsing the first rule.
5410 (check_and_convert_grammar): Search for it here after all grammar
5411 declarations have been parsed. Skip midrules, which have dummy LHS
5413 * src/symtab.c (symbol_is_dummy): New function.
5414 * src/symtab.h (symbol_is_dummy): Declare it.
5415 * tests/input.at (%start after first rule): New test.
5417 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
5419 Redo some of the previous commit: add back the ability to use
5420 non-aliased/undeclared string literals since it might be useful to
5421 those declaring %token-table.
5422 * src/reader.c (check_and_convert_grammar): Undo changes in previous
5423 commit: don't worry about complaints from symbols_pack.
5424 * src/symtab.c (symbol_new, symbol_class_set,
5425 symbol_check_alias_consistency): Undo changes in previous commit: count
5426 each string literal as a new symbol and token, assign it a symbol
5427 number, and don't complain about non-aliased string literals.
5428 (symbols_pack): Since symbol_make_alias still does not decrement symbol
5429 and token counts but does still set aliased tokens to the same number,
5430 symbol_pack_processor now leaves empty slots in the symbols array.
5432 * tests/regression.at (Undeclared string literal): Remove test case
5433 added in previous commit since non-aliased string literals are allowed
5435 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
5436 remove unnecessary string literal declarations.
5437 * tests/sets.at (Firsts): Likewise.
5439 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
5441 Don't allow an undeclared string literal, but allow a string literal to
5442 be used before its declaration.
5443 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
5444 symbols_pack complained.
5445 * src/symtab.c (symbol_new): Don't count a string literal as a new
5447 (symbol_class_set): Don't count a string literal as a new token, and
5448 don't assign it a symbol number since symbol_make_alias does that.
5449 (symbol_make_alias): It's not necessary to decrement the symbol and
5450 token counts anymore. Don't assume that an alias declaration occurs
5451 before any uses of the identifier or string, and thus don't assert that
5452 one of them has the highest symbol number so far.
5453 (symbol_check_alias_consistency): Complain if there's a string literal
5454 that wasn't declared as an alias.
5455 (symbols_pack): Bail if symbol_check_alias_consistency failed since
5456 symbol_pack asserts that every token has been assigned a symbol number
5457 although undeclared string literals have not.
5458 * tests/regression.at (String alias declared after use, Undeclared
5459 string literal): New test cases.
5460 (Characters Escapes, Web2c Actions): Declare string literals as
5462 * tests/sets.at (Firsts): Likewise.
5464 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
5466 In the grammar scanner, STRING_FINISH unclosed constructs and return
5467 them to the parser in order to improve error messages.
5468 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
5469 SC_BRACED_CODE, SC_PROLOGUE): Implement.
5470 * tests/input.at (Unclosed constructs): New test case.
5471 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
5474 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
5477 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
5479 Handle string aliases for character tokens correctly.
5480 * src/symtab.c (symbol_user_token_number_set): If the token has an
5481 alias, check and set its alias's user token number instead of its own,
5482 which is set to indicate the alias. Previously, every occurrence of
5483 the character token in the grammar overwrote that alias indicator with
5485 * tests/input.at (String aliases for character tokens): New test.
5487 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
5489 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
5491 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
5493 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
5494 to prevent failures when building on older platforms.
5495 Check for autopoint failure.
5496 Set XGETTEXT_OPTIONS to values that check for C format strings,
5497 so that translators are warned about them (this also helps
5498 prevent core dumps).
5500 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
5501 function, since it simplifies our code a bit.
5503 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
5504 rather than -W, so we don't get bogus warnings about sign comparisons.
5505 Add -Wpointer-arith, since that warning is useful (it reports code
5506 that does not conform to C89 and that some compilers reject).
5507 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
5508 since it's no longer needed.
5510 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
5512 Clean up scanners a bit.
5513 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
5514 definitions so gcc won't warn when obstack_for_string is unused.
5515 * src/scan-code.l: config.h and system.h are already #include'd by
5516 scan-code-c.c, so get rid of them here.
5517 * src/scan-gram.l: Likewise.
5518 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
5519 definitions rather than duplicating the rest of it.
5520 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
5522 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
5524 Suppress signed/unsigned comparison warnings for yycheck.
5525 * data/c.m4 (b4_safest_int_type): New macro.
5526 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
5527 a signed int type, cast it to b4_safest_int_type first.
5528 * data/yacc.c: Likewise.
5529 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
5532 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
5534 * doc/bison.texinfo: Fix some typos.
5536 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
5538 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
5539 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
5541 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
5542 the latest gnulib does this a different way.
5543 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
5544 translation was patched, so stop omitting it.
5546 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
5548 Enable declaration of default %printer/%destructor. Make the parser
5549 use these for all user-declared grammar symbols for which the user does
5550 not declare a specific %printer/%destructor. Thus, the parser uses it
5551 for token 0 if the user declares it but not if Bison generates it as
5552 $end. Discussed starting at

5557 * NEWS (2.3+): Mention.
5558 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
5559 declare a %destructor for a mid-rule's semantic value. It's just
5560 impossible to declare one specific to it.
5561 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
5562 code. Describe default %destructor form.
5563 * src/parse-gram.y (grammar_declaration): Parse default
5564 %printer/%destructor declarations.
5565 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
5566 and symbol_destructor_location_get rather than accessing the destructor
5567 and destructor_location members of struct symbol.
5568 (symbol_printers_output): Likewise but for %printer's.
5569 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
5571 * src/symtab.c (default_destructor, default_destructor_location,
5572 default_printer, default_printer_location): New static global
5573 variables to record the default %destructor and %printer.
5574 (symbol_destructor_get, symbol_destructor_location_get,
5575 symbol_printer_get, symbol_printer_location_get): New functions to
5576 compute the appropriate %destructor and %printer for a symbol.
5577 (default_destructor_set, default_printer_set): New functions to set the
5578 default %destructor and %printer.
5579 * src/symtab.h: Prototype all those new functions.
5580 * tests/actions.at (Default %printer and %destructor): New test to
5581 check that the right %printer and %destructor are called, that they're
5582 not called for $end, and that $$ and @$ work correctly.
5583 (Default %printer and %destructor for user-declared end token): New
5584 test to check that the default %printer and %destructor are called for
5585 a user-declared end token.
5586 * tests/input.at (Default %printer and %destructor redeclared, Unused
5587 values with default %destructor): New tests to check related grammar
5588 warnings and errors.
5590 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
5592 Clean up handling of %destructor for the end token (token 0).
5593 Discussed starting at
5594 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
5596 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
5598 Make the skeletons consistent in how they pop the end token and invoke
5600 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
5601 state, which has token number 0, since this would invoke the
5602 %destructor for the end token.
5603 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
5604 until after shifting the end token, or else it won't be popped.
5605 * data/yacc.c (yyparse): Likewise.
5607 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
5608 it's the end token. Upon termination, destroy an unshifted lookahead
5609 even when it's the end token.
5610 * data/lalr1.cc (yy::parser::parse): Likewise.
5611 * data/yacc.c (yyparse): Likewise.
5613 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
5614 value warnings for the end token when the user gives the end token a
5617 * tests/actions.at (Printers and Destructors): Test all the above.
5619 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
5621 Update to latest gnulib and gettext versions.
5622 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
5624 (gnulib_files): Add m4/warning.m4. Don't worry about files
5625 overwritten by autopoint.
5626 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
5627 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
5629 Don't use autoreconf; instead, invoke autopoint etc. by hand,
5630 so that we can remove the intl files at a better time.
5631 (intl_files_to_remove): Remove aclocal.m4, since it gets
5632 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
5633 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
5634 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
5635 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
5636 Remove datarootdir hack; no longer needed.
5637 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
5638 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
5639 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
5641 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
5642 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
5644 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5646 * bootstrap: Adjust to today's change to gnulib-tool by invoking
5647 it with --assume-autoconf='latest-stable'.
5649 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
5651 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
5652 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
5654 * src/muscle_tab.h (muscle_grow): Replace the header comments with
5655 those from muscle_tab.c since the old ones are misleading.
5657 2006-07-13 Akim Demaille <akim@epita.fr>
5659 Support %define "KEY" {VALUE}.
5660 * src/scan-code.h, src/scan-code.l (translate_action)
5661 (translate_rule_action, translate_symbol_action, translate_code):
5662 Return char *, not const char *.
5663 * src/parse-gram.y (declaration): Rename as...
5664 (prologue_declaration): this.
5665 (string_content): Remove this nonterminal, use STRING.
5666 (braceless, content, content.opt): New nonterminal.
5668 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
5670 * src/scan-gram.l (getargs.h): Don't include it.
5672 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
5674 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
5675 rather than a for-loop that declares a local bool variable. This
5676 should work around a compatibility problem with a Cray x1e C++
5677 compiler reported by Hung Nguyen in
5678 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
5679 The for-loop was introduced in the 2004-11-17 change but I don't
5680 know why it was needed.
5682 2006-07-12 Akim Demaille <akim@epita.fr>
5684 * data/c.m4: Comment changes.
5686 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
5688 * src/complain.c (error_message, ERROR_MESSAGE): New.
5690 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
5691 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
5693 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5695 * NEWS: Instead of %union, you can define and use your own union type
5696 YYSTYPE if your grammar contains at least one <type> tag.
5697 Your YYSTYPE need not be a macro; it can be a typedef.
5698 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
5699 (Union Decl, Decl Summary): Document this.
5700 * data/glr.c (YYSTYPE): Implement this.
5701 * data/glr.cc (YYSTYPE): Likewise.
5702 * data/lalr1.cc (YYSTYPE): Likewise.
5703 * data/yacc.c (YYSTYPE): Likewise.
5704 * src/output.c (prepare): Output tag_seen_flag.
5705 * src/parse-gram.y (declaration, grammar_declaration):
5706 Use 'union_seen' rather than 'typed' to determine whether
5707 %union has been seen, since grammars can now be typed without
5709 (symbol_declaration, type.opt, symbol_def):
5710 Keep track of whether a tag has been seen.
5711 * src/reader.c (union_seen, tag_seen): New vars.
5713 * src/reader.h (union_seen, tag_seen, typed): Likewise.
5714 * src/scan-code.l (untyped_var_seen): New variable.
5715 (handle_action_dollar): Adjust to above changes.
5716 (handle_action_dollar, handle_action_at):
5717 Improve overflow checking for outlandish numbers.
5718 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
5719 avoid new diagnostics generated by above changes.
5720 * tests/regression.at (YYSTYPE typedef): Add test to check
5721 for type tags without %union.
5723 * src/symlist.c (symbol_list_length): Return int, not unsigned
5724 int, since callers expect int. This may need to get revisited
5725 once we have proper integer overflow checking.
5727 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
5728 object is now static.
5730 * src/getargs.c (flags_argmatch): Return void, not int,
5731 to pacify ./configure --enable-gcc-warnings.
5733 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
5734 since last_string is already defined to FLEX_PREFIX (last_string).
5736 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5738 Implement --warnings/-W.
5739 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
5741 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
5743 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
5744 (warnings_args, warnings_types): New.
5745 (getargs, short_options, long_options): Accept -W/--warnings.
5746 Sort the options by alphabetical order, upper case letter right
5747 before its lower case.
5749 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
5751 Change %merge result type clash warnings to errors. Discussed at
5752 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
5753 * src/reader.c (record_merge_function_type): Use complain_at.
5754 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5755 declared later): Update test case results.
5757 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5759 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
5760 to be in alphabetical order.
5761 (trace_args): Spelling fixes.
5763 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5765 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
5766 so they don't collide with user-defined macros.
5767 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
5768 this was never guaranteed, and now that we're using gnulib stdint,
5769 which defines int_fast16_t to long int, the problem is exposed.
5771 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
5773 * data/c.m4 (b4_basename): Simplify a bit, since we don't
5774 need the full POSIX semantics (and weren't implementing them
5777 Adjust to Autoconf 2.60 and today's gnulib.
5778 * bootstrap (gnulib_modules): Add stdint.
5779 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
5780 no longer copies it.
5781 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
5782 since stdint needs the former and wcwidth (which is now required
5783 by mbswidth) needs the latter.
5784 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
5785 work around a compatibility glitch between gettext 0.14.6 and
5787 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
5788 Do not check for uintptr_t, since new stdint module does the right
5790 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
5791 Add stdint.h, stdint_.h, wcwidth.h.
5792 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
5793 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
5794 stdint.m4, wchar_t.m4, wcwidth.m4.
5795 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
5796 usual order for ../lib/*.h files.
5797 (file_name_split): Use last_component, not base_name, to adjust
5799 * src/parse-gram.h: Include <strverscmp.h> in the usual order
5800 for ../lib/*.h files.
5801 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
5802 Define unconditionally, since we now assume the stdint module.
5803 * src/scan-skel.l: Include <dirname.h>.
5804 (BASE_QPUTS): Use last_component, not base_name.
5805 * src/system.h: Include <unlocked-io.h> in the usual order
5806 for ../lib/*.h files. Include <stdint.h> unconditionally,
5807 since we now use the stdint module.
5808 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
5809 HAVE_UINTPTR_T, since we now use the stdint module.
5810 (base_name): Remove decl, since files now include <dirname.h>
5813 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5815 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
5817 * data/yacc.c, data/glr.c, data/location.cc: Use them.
5818 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
5820 * tests/calc.at: Adjust.
5822 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5824 * data/c.m4 (b4_basename): New.
5825 (b4_syncline): Also output the location of its invocation (from
5827 (b4_user_action, b4_define_user_action, b4_user_actions)
5828 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
5829 (b4_user_stype): New.
5830 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
5832 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5834 In the grammar file, the first column is 1 not 0 on the first line as
5835 on every other line.
5836 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
5837 * tests/input.at (Torturing the Scanner): Update output.
5839 * src/scan-gram.l (scanner_cursor): Declare it static.
5841 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5843 In warnings, say "previous declaration" rather than "first
5845 * src/symtab.c (redeclaration): Do that here.
5846 * src/reader.c (record_merge_function_type): In the case of a result
5847 type clash, report the previous declaration rather than the very first
5848 one in the grammar file.
5849 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5850 declared later): Add a third declaration to check this behavior.
5851 * tests/input.at (Incompatible Aliases): Update output.
5853 2006-06-27 Akim Demaille <akim@epita.fr>
5855 * doc/Doxyfile.in: New.
5856 * doc/Makefile.am: Use it.
5857 * src/lalr.h, src/symtab.h: Initial doxygenation.
5859 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5861 Don't miss %merge result type warnings just because the LHS types are
5862 declared after the %merge. This continues the effort of the previous
5864 * src/reader.c (get_merge_function): Don't set the merger type yet.
5865 (record_merge_function_type): New function for setting the merger type
5866 and checking for clashes.
5867 (grammar_current_rule_merge_set): Set the location of the %merge for
5869 (packgram): Invoke record_merge_function_type for each rule now that
5870 all symbol type declarations have been parsed.
5871 * src/reader.h (merger_list.type_declaration_location): New member
5872 storing the location of the first %merge from which the type for this
5873 merging function was derived.
5874 * src/symlist.h (symbol_list.merger_declaration_location): New member
5875 storing the location of a rule's %merge, if any.
5876 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5877 declared later): New test to catch the error fixed by the above patch.
5879 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5881 Get action warnings (grammar_rule_check) right even when symbol
5882 declarations appear after the rules. Discussed at
5883 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
5885 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
5886 Don't mistake the type of $$ in a midrule to be that of its parent
5888 * src/reader.c (grammar_current_rule_end): Don't invoke
5889 grammar_rule_check yet since not all symbol declarations may have been
5891 (grammar_midrule_action): Likewise.
5892 Don't record whether the midrule's $$ has been used yet since actions
5893 haven't been translated yet.
5894 Record the midrule's parent rule and its RHS index within the parent
5896 (grammar_current_rule_action_append): Don't translate the action yet
5897 since not all symbol declarations may have been parsed yet and, thus,
5898 warnings about types for $$, $n, @$, and @n can't be reported yet.
5899 (packgram): Translate the action and invoke grammar_rule_check now that
5900 all symbol declarations have been parsed.
5901 * src/scan-code.l (handle_action_dollar): Now that this is invoked
5902 after parsing the entire grammar file, the symbol list here in the case
5903 of a midrule is actually the midrule's empty RHS, so reference its
5904 parent rule's RHS where necessary.
5905 On the other hand, now that you can already know it's a midrule, you
5906 aren't forced to think $$ has the same type as its parent rule's $$.
5907 (handle_action_at): In the case of a midrule, reference the parent rule
5909 * src/symlist.c (symbol_list_new): Initialize new midrule-related
5911 (symbol_list_length): Now that this is invoked after all rules have
5912 been parsed, a NULL symbol (rather than a NULL symbol list node)
5913 terminates a rule. symbol_list_print already does this correctly.
5914 * src/symlist.h (symbol_list.midrule_parent_rule,
5915 symbol_list.midrule_parent_rhs_index): New members so that midrules can
5916 remember their relationships with their parents.
5917 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
5918 fixed by the above patch.
5919 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
5921 (Unused values): ... this old test case and...
5922 (Unused values before symbol declarations): ... this new test case.
5923 This one is the same as `Unused values' except that all symbol
5924 declarations appear after the rules in order to catch the rest of the
5925 errors fixed by the above patch.
5927 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5930 * src/reader.c (current_rule): Declare it static since it's no longer
5931 used outside this file.
5932 (grammar_current_rule_action_append): Remove redundant arguments from
5933 translate_rule_action invocation.
5934 * src/reader.h (current_rule): Remove this unused extern.
5935 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
5936 * src/scan-code.l (translate_rule_action): Likewise.
5938 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
5940 Clean up yesterday's patch.
5941 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
5943 * src/reader.c (grammar_current_rule_action_append): ... here for
5944 consistency with grammar_current_rule_symbol_append.
5945 * tests/regression.at (Braced code in declaration in rules section):
5946 Make yyerror and yylex static as usual.
5948 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
5950 Fix bug that mistakes braced code in a declaration in the rules section
5951 to be a rule action. Mentioned at
5952 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
5953 * src/scan-gram.l: Move midrule action detection from the start of the
5954 scanning of any braced code to...
5955 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
5956 action. For readability, use $2 and @2 rather than the equivalent
5958 * tests/regression.at (Braced code in declaration in rules section):
5959 New test to catch the error fixed by the above patch.
5961 Work on code readability some.
5962 * src/scan-code.l (current_rule): Get rid of this misleading and
5963 redundant declaration: it's actually extern'ed in reader.h.
5964 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
5965 translate_action): Add a rule argument and use it instead of the global
5967 (translate_rule_action): This already receives current_rule through an
5968 argument, so pass it on to translate_action instead of assigning
5969 current_rule to current_rule.
5970 (translate_symbol_action, translate_code): Pass rule = NULL to
5973 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
5975 Rename %before-definitions to %start-header and %after-definitions to
5976 %end-header. Don't use these declarations to separate pre-prologue
5977 blocks from post-prologue blocks. Add new order-independent
5978 declarations %before-header and %after-header as alternatives to the
5979 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
5980 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
5981 * NEWS (2.3+): Update for these changes.
5982 * data/glr.c (b4_before_definitions): Update to...
5983 (b4_start_header): ... this.
5984 (b4_after_definitions): Update to...
5985 (b4_end_header): ... this.
5986 * data/glr.cc: Likewise.
5987 * data/lalr1.cc: Likewise.
5988 * data/yacc.c: Likewise.
5989 * doc/bison.texinfo (The prologue): Update names, and replace remaining
5990 prologue blocks with %*-header declarations.
5991 (Calc++ Parser): Likewise.
5992 (Decl Summary): Update names.
5993 (Table of Symbols): Update description.
5994 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
5995 (PERCENT_END_HEADER): ... this.
5996 (PERCENT_BEFORE_DEFINITIONS): Update to...
5997 (PERCENT_START_HEADER): ... this.
5998 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
5999 (declaration): Update token names and m4 macro names.
6000 When parsing %end-header and %start-header, invoke translate_code
6001 before muscle_code_grow, and no longer set global booleans to remember
6002 whether these declarations have been seen.
6003 Parse new %after-header and %before-header.
6004 * src/reader.c (before_definitions, after_definitions): Remove.
6005 (prologue_augment): Accept a new bool argument to specify whether to
6006 augment the pre-prologue or post-prologue.
6007 * src/reader.h (before_definitions, after_definitions): Remove these
6009 (prologue_augment): Add new bool argument.
6010 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
6011 (PERCENT_END_HEADER): ... this.
6012 (PERCENT_BEFORE_DEFINITIONS): Update to...
6013 (PERCENT_START_HEADER): ... this.
6014 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6015 * tests/actions.at (Printers and Destructors): Update names.
6017 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
6019 Add comparison operators for C++ location classes. Discussed at
6020 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
6021 * data/c++.m4 (b4_define_location_comparison): New boolean %define
6022 declaration indicating whether filename_type has an operator==. If
6023 filename_type is `std::string', it defaults to `1', `0' otherwise.
6024 * data/location.cc: Iff b4_define_location_comparison is `1', add
6025 operator== and operator!= for class position and for class location.
6028 * src/scan-action.l: Remove unused file.
6029 * src/symtab.c (symbol_printer_set): Use printer_location not
6030 destructor_location.

6033 * tests/input.at (Incompatible Aliases): Update output with correct
6036 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
6038 Don't put the pre-prologue in the header file. For the yacc.c code
6039 file and the glr.c header and code files, move the pre-prologue before
6040 the token definitions. Add new %before-definitions and
6041 %after-definitions to declare code that will go in both the header file
6042 and code file. Discussed at
6043 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
6044 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
6046 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
6047 * NEWS (2.3+): Describe these changes.
6048 * data/glr.c (b4_pre_prologue): Move from within to before...
6049 (b4_shared_declarations): ... this.
6050 Add new b4_before_definitions before b4_token_enums.
6051 Add new b4_after_definitions at the end.
6052 * data/glr.cc (b4_pre_prologue): Replace with...
6053 (b4_before_definitions): ... this in the header file.
6054 (b4_after_definitions): New near the end of the header file.
6055 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
6056 code file right before including the header file.
6057 (b4_before_definitions): New in the previous position of
6058 b4_pre_prologue in the header file.
6059 (b4_after_definitions): New near the end of the header file.
6060 * data/yacc.c: Clean up some m4 quoting especially in the header file.
6061 (b4_token_enums_defines): In the code file, move to right before
6062 YYSTYPE for consistency with the header file.
6063 (b4_before_definitions): New right before b4_token_enums_defines in
6064 both the header and code file.
6065 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
6066 header and code file.
6067 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
6068 of prologues for %union dependencies.
6069 (Decl Summary): In %defines description, mention the effect of
6070 %before-definitions and %after-definitions on the header file.
6071 (Calc++ Parser): Forward declare driver in a %before-definitions rather
6072 than in the pre-prologue so that make check succeeds.
6073 (Table of Symbols): Add entries for %before-definitions and
6075 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
6076 %before-definitions.
6077 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
6078 (declaration): Parse those declarations and append to
6079 b4_before_definitions and b4_after_definitions, respectively.
6080 * src/reader.c (before_definitions, after_definitions): New bools to
6081 track whether those declarations have been seen.
6082 (prologue_augment): Add to the post-prologue if %union,
6083 %before-definitions, or %after-definitions has been seen.
6084 * src/reader.h (before_definitions, after_definitions): New extern's.
6085 * src/scan-gram.l: Scan the new declarations.
6086 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
6087 prologue block in a %before-definitions or a %after-definitions based
6088 on whether the %union is declared.
6089 * tests/regression.at (Early token definitions with --yacc, Early token
6090 definitions without --yacc): Move tests for token definitions into the
6091 post-prologue since token names are no longer defined in the
6094 2006-06-20 Akim Demaille <akim@epita.fr>
6096 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
6097 (symbol_get): Use it.
6098 * src/parse-gram.y: Use it.
6100 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
6102 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
6103 build succeeds when configured with --enable-gcc-warnings.
6105 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
6107 * src/parse-gram.y (char_name): New function.
6108 (CHAR, STRING, string_content): For %printer, properly escape.
6109 (ID): Prefer fputs to fprintf.
6110 (id): Reindent to be consistent with other rules.
6111 Properly quote char.
6113 The Translation Project changed its way of publishing translations
6114 to maintainers. I haven't received any responses to my request
6115 for supporting the old way, or for documenting the new way. I
6116 have modified 'bootstrap' to use screen scraping
6117 (in this case, HTML scraping). This is unreliable and inelegant,
6118 but I don't see any better way. Yuck.
6119 * bootstrap (TP_URL, WGET_COMMAND): New vars.
6120 (get_translations): New function, which uses HTML scraping to
6121 deduce locations of latest translations.
6122 Use this function to grab both bison and bison-runtime .po files.
6123 Don't bother priming the pump for the runtime-po domain any more,
6124 as it's now translated better than bison is.
6126 2006-06-19 Akim Demaille <akim@epita.fr>
6128 * src/scan-gram.l: No longer "parse" things after `%union' until
6129 `{'. Rather, return a single "%union" token.
6130 No longer make symbols: return strings, and leave the conversion
6131 to symbols to the parser.
6132 (SC_PRE_CODE, token_type): Remove.
6133 * src/parse-gram.y (%union): New field `character'.
6136 (ID, ID_COLON): Now that the scanner no longer makes them
6137 identifiers, adjust all uses to invoke symbol_get.
6138 (id_colon): New, wraps the conversion from string to symbol.
6139 (%union): Accept a possible union_name.
6140 (symbol): Now can be a char.
6141 * data/c.m4 (b4_union_name): Leave a default value.
6142 * data/glr.c, data/yacc.c: Use it.
6144 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
6146 For associating token numbers with token names for "yacc.c", don't use
6147 #define statements unless `--yacc' is specified; always use enum
6148 yytokentype. Most important discussions start at:
6149 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
6150 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
6152 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
6153 * NEWS (2.3+): Mention.
6154 * data/c.m4 (b4_yacc_if): New.
6155 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
6157 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
6158 on token name definitions.
6159 * src/getargs.c (usage): Capitalize `Yacc' in English.
6160 * src/output.c (prepare): Define b4_yacc_flag.
6161 * tests/regression.at (Early token definitions): Test that tokens names
6162 are defined before the pre-prologue not just before the post-prologue.
6163 Remove this test case and copy to...
6164 (Early token definitions with --yacc): ... this to test #define's.
6165 (Early token definitions without --yacc): ... and this to test enums.
6167 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
6169 * NEWS: Reword the post-2.3 change to not be so optimistic about
6170 removing the old "look-ahead" spelling.
6171 Update previous look-ahead/lookahead change reports.
6172 * REFERENCES: look-ahead -> lookahead (since that's
6173 what he actually wrote).
6174 * doc/refcard.tex: look ahead -> lookahead,
6175 look-ahead -> lookahead
6177 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
6179 For consistency, use `lookahead' instead of `look-ahead' or
6180 `look_ahead'. Discussed starting at
6181 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>

6254 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
6256 * TODO: Add request from Nelson H. F. Beebe to be able to install
6257 Bison without installing the yacc script.
6259 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
6261 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
6262 and yytext if they're already #define'd.
6263 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
6264 * src/scan-code-c.c: ... here.
6265 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
6268 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
6270 Get Bison to build again when configured with --enable-gcc-warnings.
6271 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
6273 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
6274 loc argument as it shadows a global.
6275 * src/scan-gram.l: Remove stray comma that prevents boundary_set
6278 * src/.cvsignore: Add scan-code.c.
6280 2006-06-07 Akim Demaille <akim@epita.fr>
6282 * src/scan-gram.l: Move the "add a trailing ; to actions" code
6284 * src/scan-code.l: here.
6285 * tests/input.at (Torturing the Scanner): Fix another location
6288 2006-06-07 Akim Demaille <akim@epita.fr>
6290 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
6292 2006-06-06 Akim Demaille <akim@epita.fr>
6294 Extract the parsing of user actions from the grammar scanner.
6295 As a consequence, the relation between the grammar scanner and
6296 parser is much simpler. We can also split "composite tokens" back
6298 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
6299 * src/scan-gram.l (add_column_width, adjust_location): Move to and
6301 * src/location.h, src/location.c (add_column_width)
6302 (location_compute): these.
6303 Fix the column count: the initial column is 0.
6304 (location_print): Be robust to ending column being 0.
6305 * src/location.h (boundary_set): New.
6306 * src/main.c: Adjust to scanner_free being renamed as
6308 * src/output.c: Include scan-code.h.
6309 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
6311 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
6312 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
6313 which is now, again, a separate token.
6314 Adjust all dependencies.
6315 Whereever actions with $ and @ are used, use translate_code.
6316 (action): Remove this nonterminal which is now useless.
6317 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
6318 (grammar_current_rule_action_append): Use translate_code.

6322 (scanner_initialize, scanner_free, scanner_last_string_free)
6323 (gram_out, gram_lineno, YY_DECL_): Move to...
6324 * src/scan-gram.h: this new file.
6325 (YY_DECL): Rename as...
6327 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
6328 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
6329 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
6330 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):

6336 (increment_rule_length): Remove.
6337 (last_braced_code_loc): Rename as...
6338 (gram_last_braced_code_loc): this.
6339 Adjust to the changes of the parser.
6340 Move all the handling of $ and @ into...
6341 * src/scan-code.l: here.
6342 * src/scan-gram.l (handle_dollar, handle_at): Remove.
6343 (handle_action_dollar, handle_action_at): Move to...

6355 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
6357 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
6358 Use Akim's wording from
6359 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
6361 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
6363 Between Bison releases, manually append `+' to the previous Bison
6364 release number, and use that as a signal to automatically print the
6365 ChangeLog's CVS Id keyword from --version. Discussed starting at
6366 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
6367 * ChangeLog: Add Id header.
6368 * configure.ac (AC_INIT): Append `+' to `2.3'.
6369 * src/.cvsignore: Add revision.c.
6370 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
6371 (BUILT_SOURCES): Add revision.c.
6372 (revision.c): New target rule. This file defines a new global variable
6373 named revision. It initializes it with either the Id from ChangeLog
6374 or, if VERSION doesn't contain `+', with the empty string.
6375 * src/getargs.c (version): Print the value of revision.
6376 * src/revision.h: Extern revision.
6378 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
6380 * NEWS: Version 2.3.
6381 * configure.ac (AC_INIT): Likewise.
6383 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
6385 * data/glr.c (YYRECOVERING): Define to be a function-like macro
6386 with no arguments, not as an object-like macro. This is for
6387 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
6388 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
6389 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
6392 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
6394 * src/getargs.c (usage): Back out yesterday's modification of the
6395 --help output so that we don't have to wait for translation before
6398 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
6400 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
6401 Problem reported by Akim Demaille.
6403 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
6405 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
6407 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
6409 * data/yacc.c (yy_reduce_print): Omit trailing white space in
6410 generated source code. Problem reported by Frans Englich in
6411 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
6413 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
6415 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
6416 shell, not within 'make', so that 'make' by an ordinary builder
6417 (using GNU make) does not worry about configuring gzip. This also
6418 works around a bug reported independently by Keith Thompson and by
6419 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
6420 stderr rather than stdout, messing up the build logs.
6422 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
6424 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
6425 to make sure that YYID will never be unused. This fixes a 'make
6426 maintainer-check' failure caused by the recent changes to the 'Trivial
6427 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
6429 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
6431 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
6433 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
6434 state before an empty RHS is always resolved here. Only the location
6435 of that state is guaranteed to be resolved, and that's enough. This
6436 fixes the remaining bug reported by Derek M. Jones in
6437 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6438 * tests/glr-regression.at (Uninitialized location when reporting
6439 ambiguity): Test the above case.
6440 Also, the embedded comments in this test case claim it checks the case
6441 of an empty RHS that has inherited the initial location. However, the
6442 corresponding LHS was already resolved, so yyresolveLocations didn't
6443 actually have reason to modify it. Fix this by forcing
6444 nondeterministic operation at the beginning of the parse.

6448 * data/c.m4 (b4_yy_symbol_print_generate):
6449 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
6450 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
6451 of the bugs reported today by Derek M Jones in
6452 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6453 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
6454 defined to be a type name without parens or brackets.
6455 (Location Type): Similarly for YYLTYPE.
6456 * tests/regression.at (Trivial grammars): Put in a test for this
6457 bug that will be caught by 'make maintainer-check' (though not,
6458 alas, by 'make check' unless your compiler is picky).

6467 * data/glr.c (yyreportTree): Make room in yystates for the state
6468 preceding the RHS. This fixes the segmentation fault reported by Derek
6470 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
6471 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
6472 to the user. Reported for yyreportTree by Derek M. Jones later in the

6476 Fix typo in Steve Murphy's name.
6478 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6480 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
6481 checking against YYLAST that caused the parser to miss a potential
6482 alternative in its diagnostic.
6483 Problem reported by Maria Jose Moron Fernandez in
6484 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
6485 * data/lalr1.cc (yysyntax_error_): Likewise.
6486 * data/yacc.c (yysyntax_error): Likewise.
6487 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
6488 tokens, in case we run into an older C compiler.
6489 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
6490 Use them to check for the off-by-one error fixed above.
6492 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
6493 YYSIZE_T, not size_t.
6494 * tests/regression.at (Trivial grammars): New test, to catch
6495 the error fixed by the above patch.
6497 2006-05-14 Akim Demaille <akim@lrde.epita.fr>

6510 Implement --trace=m4.
6511 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
6512 * src/output.c (output_skeleton): When set, pass -dV to m4.
6514 Factor the handling of flags in m4.
6515 * src/output.c (prepare): Rename the muscle names debug, defines,
6516 error_verbose to debug_flag, defines_flag, error_verbose_flag.
6517 * data/c.m4: Adjust.
6518 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
6519 Use b4_define_flag_if to define other b4_FLAG_if macros.
6520 (b4_location_if): As a consequence, rename as...
6521 (b4_locations_if): this, for consistency.
6522 Adjust all the skeletons.
6524 2006-05-14 Akim Demaille <akim@lrde.epita.fr>

6533 Adjust dependencies.
6535 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6537 * data/c.m4 (b4_copyright): Put the special exception for Bison
6538 skeletons here, so we don't have to put it in each skeleton. All
6539 uses changed. Suggested by Akim Demaille. Also, wrap the
6540 copyright notice, in case it is longer than 80 columns. Replace
6541 comma by newline after title.
6543 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6545 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
6546 incompatibility, not a bug. Mention that it wasn't fixed as of
6549 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
6551 * examples/extexi: Enforce the precedence of concatenation over

6555 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
6557 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
6558 with the member "token".
6559 Reported by Martin Nylin.
6561 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
6563 * data/glr.c: Switch to Bison 2.2 special-exception language in
6564 the copyright notice. Use more-regular format for titles and

6574 * data/glr.cc: Remove dead code.
6576 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6578 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
6579 that variable and the line breaks the bootstrap. Problem reported
6580 by Juan M. Guerrero.

6600 Problem reported by Bob Rossi.
6602 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
6604 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
6605 and didn't really work.
6606 For the index, use @ifnotinfo, not @iftex.
6607 Minor cleanups of spacing and terminology.
6609 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
6611 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
6612 of AT_NAME_PREFIX when %name-prefix is not used.
6614 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
6616 Apply --prefix to C++ skeletons too: they change the namespace.
6617 The test suite already exercize these cases.
6618 * data/c++.m4 (b4_namespace): New.
6619 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
6620 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
6621 * data/yacc.c, data/glr.c: Remove a useless `[]'.
6622 * doc/bison.texinfo: Document it.
6623 (Option Cross Key): Use @multitable in all formats. It looks
6624 nicer, even in TeX outputs.
6625 (Rules): Use the same code whatever the output type is.
6626 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
6627 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
6628 * tests/calc.at: Use it, instead of hard coding `yy'.

6649 Fix two nits reported by twlevo, plus one more that I discovered.
6651 * src/assoc.h (assoc_to_string): Give a name to the arg, as
6652 this is the usual Bison style.
6653 * src/location.h (location_print): Likewise.
6655 * src/reader.h (token_name): Likewise.
6657 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
6659 Fix some nits reported by twlevo.
6660 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
6661 and "POSIX". Use more-modern syntax for URLs. Mention C++
6662 and ask for Java. Don't hardwire OS version numbers. Add
6664 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
6665 * src/conflicts.c (solved_conflicts_obstack): Now static.
6667 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
6669 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
6670 page. Say "you can use it" not "you may use it" as on the web page;
6671 we're describing capabilities not granting permission.
6673 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
6675 * data/glr.c (yyresolveLocations): Rename local variables to avoid
6676 shadowing warnings. Use usual patter for iterating through RHS.
6677 * tests/glr-regression.at
6678 (Uninitialized location when reporting ambiguity):
6679 Modify yylex so that it uses its argument, rather than trying
6680 to rely on ARGSUSED (which doesn't work for gcc with warnings).
6681 const char -> char const.
6683 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
6684 Don't use tabs inside commands; it messes up 'ps'.
6685 Problem reported by twlevo.
6687 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
6689 * tests/glr-regression.at (Uninitialized location when reporting
6690 ambiguity): New test case.
6691 * data/glr.c (yyresolveLocations): New function, which uses
6693 (yyresolveValue): Invoke yyresolveLocations before reporting an
6695 * doc/bison.texinfo (Default Action for Locations): Note
6696 YYLLOC_DEFAULT's usage for ambiguity locations.
6697 (GLR Semantic Actions): Cross-reference those notes.
6699 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
6701 * tests/glr-regression.at (Leaked semantic values when reporting
6702 ambiguity): Remove unnecessary union and type declarations.
6703 (Leaked lookahead after nondeterministic parse syntax error): New test
6705 * data/glr.c (yyparse): Check for zero stacks remaining before
6706 attempting to shift the lookahead so that you don't lose it.
6708 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6710 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
6711 * tests/glr-regression.at (Leaked semantic values when reporting
6712 ambiguity): New test case.
6713 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
6714 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
6715 now unnecessary yystackp parameter.
6716 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
6717 destructors can be called.
6719 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
6720 in existing testcases.
6722 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6724 Don't leak semantic values for parent RHS when a user action cuts the
6725 parser, and clean up related code a bit.
6726 * tests/glr-regression.at (Leaked merged semantic value if user action
6727 cuts parse): Rename to...
6728 (Leaked semantic values if user action cuts parse): ... this. Add check
6729 for leaked parent RHS values.
6730 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
6731 between an unresolved state (non-empty chain of semantic options) and
6732 an incomplete one (signaled by an empty chain).
6733 (yyresolveStates): Document the interface. Move all manipulation of a
6734 successfully or unsuccessfully resolved yyGLRState to...
6735 (yyresolveValue): ... here so that yyresolveValue always leaves a
6736 yyGLRState with consistent data and thus is easier to understand.
6737 Remove the yyvalp and yylocp parameters since they are always just
6738 taken from the yys parameter. When reporting a discarded merged value
6739 in debugging output, note that it is incompletely merged. Document the
6741 (yyresolveAction): If resolving any of the RHS states fails, destroy
6742 them all rather than leaking them. Thus, as long as user actions are
6743 written to clean up the RHS correctly, yyresolveAction always cleans up
6744 the RHS of a semantic option. Document the interface.

6749 led to a segmentation fault in GNU Pascal. Problem reported
6752 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
6754 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
6755 mid-rule action inside a nonterminal symbol in order to declare a
6756 destructor for its semantic value.

6808 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
6810 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
6811 nodist_PROGRAMS, since we don't need to actually compile the
6812 example if we're just doing a plain 'make'. This avoids bothering
6813 the installer unnecessarily about problems due to weird C++

6822 not portable, according to Posix and the C standard, and it does
6823 not work with Sun C 5.7, where previous #line directives affect

6843 that '#include <string>' works.

6863 During deterministic GLR operation, user actions should be able to
6864 influence the parse by changing yychar. To make this easier to fix and
6865 to make glr.c easier to evolve in general, don't maintain yytoken in
6866 parallel with yychar; just compute yytoken when needed.

6873 yychar rather than *yytokenp to determine the current lookahead.
6874 Compute yytoken locally when needed.

6893 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
6894 got from <http://bro-ids.org/download.html>. The bug is that
6895 when two actions appeared in succession, the second one was
6896 scanned before the first one was added to the grammar rule
6897 as a midrule action. Bison then output the incorrect warning
6898 "parse.y:905.17-906.36: warning: unused value: $3".
6899 * src/parse-gram.y (BRACED_CODE, action): These are no longer
6900 associated with a value.

6903 * src/reader.c (grammar_midrule_action): Now extern.
6904 (grammar_current_rule_action_append): Don't invoke
6905 grammar_midrule_action; that is now the scanner's job.
6906 * src/reader.h (last_string, last_braced_code_loc):
6907 (grammar_midrule_action): New decls.
6908 * src/scan-gram.l (last_string): Now extern, sigh.

6919 All used changed. Check whether the symbol has a destructor,
6920 not whether it is typed.

7160 in the yychar entry.
7161 In the yychar entry, remove mention of the local yychar case (pure
7162 parser) since this is irrelevant information when writing semantic
7163 actions and since it's already discussed in `Table of Symbols' where
7164 yychar is otherwise described as an external variable.
7165 In the yychar entry, don't call it the `current' look-ahead since it
7166 isn't when semantic actions are deferred.
7167 In the yychar and yyclearin entries, add note about deferred semantic
7169 Add yylloc and yylval entries discussing look-ahead usage.
7170 (Look-Ahead Tokens): When discussing yychar, don't call it the

7191 appropriately during nondeterministic operation.
7192 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
7193 members to store the current lookahead to be used by the deferred
7195 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
7196 from which the RHS is taken. Set the lookahead members of the new
7197 yySemanticOption according to the lookahead status for stack yyk.

7199 yyaddDeferredAction.
7200 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

7211 (Incorrect lookahead during nondeterministic GLR): New test case.
7213 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

7225 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
7227 * data/glr.c (yyresolveValue): When merging semantic options, if at
7228 least one user action succeeds but a later one cuts the parse, then
7229 destroy the semantic value before returning rather than leaking it.
7230 (yyresolveStates): If a user action cuts the parse and thus
7231 yyresolveValue fails, ignore the (unset) semantic value rather than
7232 corrupting the yyGLRState, and empty the semantic options list since
7233 the user actions should have called all necessary destructors.
7234 Simplify code with YYCHK.
7235 * tests/glr-regression.at (Corrupted semantic options if user action
7236 cuts parse): New test case.
7237 (Undesirable destructors if user action cuts parse): New test case.

7535 sed out the final state number.
7537 Work around portability problem on Solaris 10: flex-generated
7538 files include <stdio.h> before <config.h>, which messes up
7539 because the latter defines __EXTENSIONS__. Address the problem
7540 by creating two new little files that include <config.h> first,
7541 then include the flex-generated files. Rewrite everyone else

7619 it's no longer just a file.
7620 * data/glr.c: Grant a special exception for C GLR parsers, that
7621 reads like the already-existing exception for C LALR(1) parsers.

7875 (YYDPRINTF, YY_SYMBOL_PRINT, YY_STACK_PRINT, YY_REDUCE_PRINT):
7876 (yyerrorlab): Use /*CONSTCOND*/ to suppress lint warnings.
7879 * data/m4sugar/m4sugar.m4 (_m4_map): New macro.
7880 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
7882 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
7884 Undo the parts of the unlocked-I/O change that substituted
7885 putc or puts for printf. This might hurt performance a bit,
7886 but some people prefer the printf style.
7887 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
7888 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

7909 unused-variable warnings.
7911 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

7915 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
7917 Use unlocked I/O for a minor performance improvement on hosts like
7918 GNU/Linux and Solaris that support unlocked I/O. The basic idea
7919 is to use the gnlib unlocked-io module, and to prefer putc and
7920 puts to printf when either will work (since the latter doesn't
7921 come in an unlocked flavor).
7922 * bootstrap (gnulib_modules): Add unlocked-io.
7923 * data/c.m4 (yysymprint): Prefer puts and putc to printf.

7941 * src/system.h: Include unlocked-io.h rather than stdio.h.
7943 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as

7993 to allow support for non-posix systems. This is a no-op function
7996 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
7997 handle the lack of pipe/fork functionality on non-posix systems.

8036 (parser::semantic_value): Now a full definition instead of an
8037 indirection to YYSTYPE.

8081 local variables whose names begin with 'yy'.
8082 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
8083 Trivial changes from Joel E. Denny.
8085 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
8087 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
8088 don't use alloca any more.
8090 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
8091 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
8092 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.

8096 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
8098 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This

8103 This works a bit better with glibc, if user code has already included
8105 * doc/bison.texinfo (Bison Parser): Document that users can't
8106 arbitrarily use malloc and free for other purposes. Document
8107 that <alloca.h> and <malloc.h> might be included.

8122 (yysyntax_error): New function.
8123 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
8124 multiple syntax errors are reported, and alloca is being used.
8125 Instead, reallocate buffers twice as big each time, so that
8126 we waste at most half the allocated memory. Start with a small
8127 (128-byte) buffer that will suffice in most cases anyway.
8128 Use yysyntax_error to do most of the work.
8130 * doc/bison.texinfo (Error Reporting, Table of Symbols):
8131 yynerrs is the number of errors reported, not the number of

8138 Don't start user-code symbols with "yy", to avoid name space problems.
8140 2005-09-19 Akim Demaille <akim@epita.fr>
8142 Remove the traits, failed experiment.
8143 It never proved useful, and anyway because of the current
8144 definition, it was not possible to have several specialization of
8145 this traits, making it useless.
8146 * data/lalr1.cc (yy:traits): Remove.
8147 Inline its definitions in the parser class.
8149 2005-09-19 Akim Demaille <akim@epita.fr>

8172 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
8173 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
8174 is not defined. This is an awful hack, but it's enough for now.
8175 All callers changed.
8176 * tests/glr-regression-at (make_value): Args are const pointers now,
8177 to avoid GCC warning.
8178 (Duplicated user destructor for lookahead): New test. Currently
8179 skipped. It fails on my host but I'm not sure it'll always fail.
8181 2005-09-16 Akim Demaille <akim@epita.fr>
8183 * src/symtab.h (struct symbol): Declare the printer and destructor
8184 as const, to avoid accidental calls to free.

8201 * data/lalr1.cc (yylex_): Remove, inline its code.
8202 (yyreport_syntax_error_): Remove, replaced by...
8203 (yysyntax_error_): this which returns a string and leaves to the
8204 caller the call to the users' error function.
8205 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
8206 Move from members of the parser object...
8207 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):

8231 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
8232 do anything if $@ exists. This reverts part of the 2005-07-07
8235 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
8237 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
8238 contains obsolete information and isn't worth distributing as a
8239 separate file anyway.
8240 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
8241 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

8248 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
8249 Suggested by twlevo@xs4all.nl.
8251 * data/glr.c (YYCHK1): Do not assume YYE is in range.

8253 Problem reported by twlevo@xs4all.nl.
8255 * doc/bison.texinfo: Don't use "filename", as per GNU coding
8256 standards. Use "file name" or "file" or "name", depending on
8258 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
8259 not to hack/foo.tab.c.
8260 (Calc++ Top Level): 2nd arg of main is not const.
8261 * data/glr.c: b4_filename -> b4_file_name.

8343 All callers changed to avoid the newline.
8344 (yyprocessOneStack): Output two lines rather than one, to accommodate
8345 the above change. This changes the debug output format slightly.
8347 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
8348 reported by Joel E. Denny in
8349 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
8351 * tests/glr-regression.at (Duplicate representation of merged trees):
8352 New test, from Joel E. Denny in:
8353 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
8354 * THANKS: Add Joel E. Denny.
8356 * configure.ac (AC_INIT): Bump to 2.0c.
8358 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
8360 * NEWS: Version 2.0b.
8362 * Makefile.am (SUBDIRS): Put examples before tests, so that
8363 "make check" doesn't finish with "All 1 tests passed".
8365 * tests/regression.at (Token definitions): Don't rely on
8366 AT_PARSER_CHECK for data that contains backslashes. It currently
8367 uses 'echo', and 'echo' isn't portable if its argument contains
8368 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
8369 that the byte '\0xff' is not printable in the C locale; it is,
8370 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
8371 not printable, so use '\0x81' to test.
8373 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
8374 version of GCC, since the macro is used with non-GCC compilers.
8376 Fix core dump reported by Pablo De Napoli in
8377 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
8378 * tests/regression.at (Invalid inputs with {}): New test.
8379 * src/parse-gram.y (token_name): Translate type before using
8382 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
8383 the user's name space. All uses changed to __attribute__
8385 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
8386 Add __attribute__ ((__noreturn__)).
8388 * etc/clcommit: Remove. We weren't using it, and it failed
8389 "make maintainer-distcheck".
8390 * Makefile.maint: Merge from coreutils.
8391 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
8392 (syntax-check-rules): Change list of rules as described below.
8393 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
8394 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
8395 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):

8401 (makefile-check, po-check, author_mark_check):
8402 (makefile_path_separator_check, copyright-check):
8403 Use grep -n, to make it easier to find violations.
8404 Use CVS_LIST and CVS_LIST_EXCEPT.
8405 (header_regexp, h_re): Remove.
8407 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
8408 (my-distcheck): Use more-modern GCC flags.
8409 (signatures, %.asc): Remove.
8410 (rel-files, announcement): Remove signatures.
8411 Restore old updating code, even though we don't use it, so
8412 that we're the same as coreutils.
8413 (alpha, beta, major): Depend on news-date-check.
8414 Make the upload commands.
8416 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
8417 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
8418 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
8419 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.

8421 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
8422 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
8423 * tests/sets.at: Likewise.
8425 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
8426 we comment out the Autoconf version number.
8427 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
8428 it's error-prone and "make maintainer-distcheck" rejects it.
8430 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
8431 Indent calls to "error" to pacify "make maintainer-distcheck",
8432 when the calls are not intended to be translated.
8433 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
8435 * src/Makefile.am (DEFS): Use +=, to pacify
8436 "make maintainer-distcheck".
8437 (bison_SOURCES): Add scan-skel.h.
8438 (sc_tight_scope): New rule, from coreutils.
8440 * src/files.c (src_extension, header_extension):
8441 Now static, not extern.
8442 * src/getargs.c (short_options): Likewise.
8443 * src/muscle_tab.c (muscle_table): Likewise.
8444 * src/parse-gram.y (current_class, current_type, current_prec):
8446 * src/reader.c (grammar_end, previous_rule_end): Likewise.
8447 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
8448 * src/main.c (main): Cast bindtextdomain and textdomain calls to
8449 void, to avoid warning when NLS is disabled.
8450 * src/output.c: Include scan-skel.h.
8451 (scan_skel): Remove decl, since scan-skel.h does this.
8453 Indent calls to "error" to pacify "make maintainer-distcheck".
8454 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
8455 * src/reader.h (gram_end, gram_lineno): New decls to pacify
8456 "make maintainer-distcheck".
8457 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
8458 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
8459 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
8460 (skel_lex_destroy, scan_skel): Move these decls to...
8461 * src/scan-skel.h: New file.
8462 * src/uniqstr.c (uniqstr_assert):
8463 Indent calls to "error" to pacify "make maintainer-distcheck".
8465 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
8468 * tests/torture.at: Revamp to avoid misuse of atoi that
8469 "make maintainer-distcheck" complained about.
8471 * examples/extexi (message): Don't print a message more than once,
8472 and omit line-number decoration that makes Emacs compile think
8473 that informative messages are worth worrying about.
8475 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
8477 * configure.ac: Update version number.
8479 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
8481 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
8482 autogenerated by the maintainer.
8483 * examples/calc++/.cvsignore: Add *.yy.
8485 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
8486 * lib/bitset_stats.c (bitset_stats_init): Likewise.
8487 * lib/bitsetv.c (bitsetv_alloc): Likewise.
8489 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
8491 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
8492 from maintainer-distcheck about casting the argument of 'free'.
8494 * NEWS: Mention recent yytname changes.
8495 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
8497 * bootstrap: For translations that have not yet been upgraded to
8498 the new runtime-po domain, prime the pump by extracting the
8499 relevant strings from the obsolete translations. This code can be
8500 removed once the bison-runtime domain has been translated by each
8503 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
8504 now that token names are already quoted.
8506 Fix problem reported by Anthony Heading.
8507 * data/glr.c (YYTOKEN_TABLE): New macro.
8508 (yytname): Define if YYTOKEN_TABLE.
8509 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
8510 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
8511 (YYERROR_VERBOSE): Define the same way the other skeletons do.
8512 * src/output.c (prepare_symbols): Output token_table_flag.
8514 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
8516 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
8517 again if the first call fails.
8519 * data/glr.c (yytnamerr): New function.
8520 (yyreportSyntaxError): Use it to dequote most string literals.
8521 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
8522 with other skeletons. All uses changed.
8523 (yytnameerr_): New function.
8524 (yyreport_syntax_error): Use it to dequote most string literals.
8525 * data/yacc.c (yytnamerr): New function.
8526 (yyerrlab): Use it to decode most string literals.
8527 * doc/bison.texinfo (Decl Summary, Calling Convention):
8528 Clarify quoting convention of yytname.
8529 * src/output.c (prepare_symbols): Quote all names. This undoes
8530 the 2005-04-17 change, which is now accomplished (mostly) via
8531 changes in the parsers as described above.
8532 * tests/regression.at (Token definitions, Web2c Actions):
8533 Undo most 2005-04-17 change here, too.
8535 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
8537 Fix more problems reported by twlevo@xs4all.nl.
8538 * tests/cxx-type.at: Don't pipe output of ./types through sed to
8539 remove trailing spaces. This loses the exit status of ./types,
8540 and isn't needed since ./types shouldn't be emitting trailing
8542 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
8543 as the stack isn't valid in that case.
8545 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
8546 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
8547 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
8548 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
8550 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
8551 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
8552 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
8555 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
8556 overly-picky compilers that reject 'char *foo = "bar";'.
8558 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
8559 to FILE * parameter, not to stderr. This fixes a typo introduced
8560 in the 2005-07-12 change.
8562 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
8563 warnings from GCC 4.
8565 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
8566 (yyglrShiftDefer, yysplitStack):
8567 Remove unused parameters b4_pure_formals. All uses changed.
8568 (yyglrShift): Remove unused parameters b4_user_formals.
8570 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
8572 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
8574 Destructor cleanups and regularization among the three skeletons.
8575 * NEWS: Document the behavior changes.
8576 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
8577 stack before failing, as the cleanup code will do it for us now.
8578 * data/lalr1.cc (yyerrlab): Likewise.
8579 * data/glr.c (yyparse): Pop everything off the stack before
8580 freeing it, so that destructors get called properly.
8581 * data/lalr1.cc (yyreturn): Likewise.
8582 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
8583 This is more consistent.
8584 * doc/bison.texinfo (Destructor Decl): Mention more reasons
8585 why destructors might be called. 1.875 -> 2.1.
8586 (Destructor Decl, Decl Summary, Table of Symbols):
8587 Some English-language cleanups for %destructor.
8588 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
8589 Add output line for destructor of start symbol.
8590 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
8591 because of that same extra output line.
8593 * NEWS: Document minor wording changes in diagnostics of
8594 Bison-generated parsers.
8595 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
8596 Remove unused formals. All uses changed.
8597 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
8598 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
8599 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
8600 Rename yyoverflowab to yyexhaustedlab.
8601 When memory exhaustion occurs during syntax-error reporting,
8602 report it separately rather than in a single diagnostic; this
8604 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
8605 (Memory Exhausted): Renamed from Parser Stack Overflow.
8606 Revamp wording slightly to prefer "memory exhaustion".
8607 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
8609 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
8611 Add i18n support to the GLR skeleton. Partially fix the C++
8612 skeleton; a C++ expert needs to finish this. Remove debugging
8613 msgids; there's little point to having them translated, since they
8614 can be understood only by someone who can read the
8615 (English-language) source code.
8617 Generate runtime-po/bison-runtime.pot automatically, so that we
8618 don't have to worry about garbage getting in that file. We'll
8619 make sure after the next official release that old msgids don't
8621 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
8623 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
8625 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
8626 Fix typos in explanations of the runtime file.
8627 * bootstrap: Change gettext keyword from YYI18N to YY_.
8628 Use standard Makefile.in.in in runtime-po, since we'll arrange
8629 for backward-compatible bison-runtime.po files in a different way.
8630 * data/glr.c (YY_): New macro, from yacc.c.
8631 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
8632 Translate messages intended for users.
8633 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
8634 the wording in the other skeletons. We don't know that the memory
8636 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
8637 Use same method that yacc.c uses.
8638 Don't translate debugging messages.
8639 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
8640 it doesn't work (yet), and requires C++ expertise to fix.
8641 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
8642 Move defn to a more logical place, to be consistent with other
8644 Don't translate debugging messages.
8645 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
8646 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
8647 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
8648 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
8650 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
8651 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
8653 * tests/glr-regression.at (Badly Collapsed GLR States):
8655 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8656 yylex should return 0 at EOF rather than aborting.
8658 Improve tests for stack overflow in GLR parser.
8659 Problem reported by twlevo@xs4all.nl.
8660 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
8662 (yyStackOverflow): Just longjmp, but with value 2 so that caller
8663 can handle the problem.
8664 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
8665 (yyparse): New local variable yyresult to record the result.
8666 Use result of setjmp to set it, rather than storing itinto
8668 (yyDone): Remove label.
8669 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
8670 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
8671 if YYABORT is used).
8672 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
8673 yyparse status; put status > 1 into diagnostic.
8674 Check that status==2 works.
8675 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
8676 Use exit status 3 for failure to open (which shouldn't happen).
8678 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
8680 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
8681 1 on syntax error; just let yyparse do its thing.
8682 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
8683 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
8684 (Exploding the Stack Size with Alloca):
8685 (Exploding the Stack Size with Malloc):
8686 Expect exit status 2, not 1, since the parser is supposed to blow
8687 its stack. Problem reported by twlevo@xs4all.nl.
8689 * data/glr.c (yyparse): Don't assume that the initial calls
8690 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
8691 Print a stack-overflow message and fail instead.
8692 Initialize the line-number information before creating the stack,
8693 so that the stack-overflow message can report line zero safely.
8695 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
8697 Fix problems reported by twlevo@xs4all.nl.
8698 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
8699 (yyuserMerge): Provide a default case if b4_mergers is empty.
8700 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
8701 * tests/glr-regression.at
8702 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8703 Add casts to pacify C++ compilers.
8704 * tests/glr-regression.at (Improper merging of GLR delayed action
8705 sets): Declare yylex before using it.
8706 * tests/Makefile.am (maintainer-check-g++): Fix a stray
8707 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
8708 test for valgrind; valgrind is independent of g++.
8709 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
8710 for compatibility with POSIX 1003.1-2001 (if running coreutils).
8711 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
8712 Use a destructor, so that we can expand the stack. Change
8713 YYSTYPE to char * so that we can free it. Cast result of malloc.
8715 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8717 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
8718 a valgrind failure. Problem reported by twlevo@xs4all.nl.
8720 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
8722 * PACKAGING: New file, suggested by Bruno Haible and taken from
8723 similar wording in gettext's PACKAGING file.
8724 * NEWS: Mention PACKAGING.
8725 * Makefile.am (EXTRA_DIST): Add PACKAGING.
8727 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
8729 * NEWS: Document recent i18n improvements.
8730 * bootstrap: Get runtime translations into runtime-po.
8731 Create runtime-po files automatically, if possible.
8732 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
8733 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
8734 does not infringe on the user's name space.
8735 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
8736 * doc/bison.texinfo (Internationalization): Revamp the English
8737 and Texinfo syntax a bit, to try to make it clearer.
8738 (Bison Options, Option Cross Key): Mention --print-localedir.
8739 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
8740 YYENABLE_NLS. Quote a bit more.
8741 * runtime-po/.cvsignore: New file.

8750 * runtime-po/Makevars: Likewise.
8751 * runtime-po/LINGUAS: Likewise.
8752 * runtime-po/de.po: Likewise; we will rely on the translation project
8753 to maintain this, so "bootstrap" should get it.
8754 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
8756 * src/main.c (main): Bind the bison-runtime domain, too.
8758 2005-07-12 Bruno Haible <bruno@clisp.org>
8760 * data/yacc.c: Include <libintl.h> when NLS is enabled.
8761 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
8762 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
8763 * runtime-po: New directory.
8764 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
8765 $(DOMAIN).pot-update rule, so that old messages are never dropped.
8766 * runtime-po/Rules-quot: New file, copied from po/.
8767 * runtime-po/quot.sed: Likewise.

8778 * m4/bison.m4: New file.
8779 * Makefile.am (SUBDIRS): Add runtime-po.
8780 (aclocaldir, aclocal_DATA): New variables.
8781 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
8783 * src/getargs.c (usage): Document --print-localedir option.
8784 (PRINT_LOCALEDIR_OPTION): New enum item.
8785 (long_options): Add --print-localedir option.
8786 (getargs): Handle --print-localedir option.
8787 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
8788 (Internationalization): New section.
8790 2005-07-12 Akim Demaille <akim@epita.fr>
8792 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
8793 for consistency with the rest of the code.
8794 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
8797 2005-07-12 Akim Demaille <akim@epita.fr>
8799 * src/parse-gram.y: Use %printer instead of YYPRINT.
8801 2005-07-12 Akim Demaille <akim@epita.fr>
8803 * src/symtab.h, src/symtab.c (symbol_print): New.
8804 * src/symlist.h, src/symlist.c (symbol_list_print): New.
8805 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
8807 2005-07-12 Akim Demaille <akim@epita.fr>
8809 * data/glr.c (b4_syncline): Fix (swap) the definitions of
8810 b4_at_dollar and b4_dollar_dollar.
8812 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
8814 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
8815 and Pennello's paper.
8817 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
8819 * data/yacc.c (yyparse): Undo previous patch. Instead,
8820 set yylsp[0] and yyvsp[0] only if the initial action
8821 sets yylloc and yylval, respectively.
8823 * data/yacc.c (yyparse): In the initial action, set
8824 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
8825 This avoids the use of undefined variables if the initial
8826 action does not set yylloc and/or yylval.
8828 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8830 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
8831 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
8832 Remove from CVS. These files are automatically generated.
8833 * examples/extexi: Clarify that this file is now part of Bison,
8834 not GNU M4, and that it works with any POSIX-compatible Awk.
8835 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
8836 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
8837 so that we also get calc++-parser.yy. Geneate it.
8838 Use $(AWK), not gawk, since any conforming Awk will do.
8839 Put comment before action, since older 'make' can't handle comment
8841 $(BUILT_SOURCES): List all built sources, not just some of them.
8842 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
8843 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
8844 $($(calc_sources_generated)): Remove unnecessary test for existence
8845 of target. (This had a shell syntax error anyway; a stray "x".)
8846 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
8848 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
8850 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
8851 implied by the other modules.
8853 2005-07-06 Akim Demaille <akim@epita.fr>
8855 Bind examples/calc++ to the package.
8856 * examples/calc++/Makefile: Remove, replaced by...
8857 * examples/calc++/Makefile.am: ... this new file.
8858 * examples/calc++/test: Remove input.
8859 * examples/calc++/compile: Remove.
8860 * examples/Makefile.am: New.
8861 * configure.ac, Makefile.am: Adjust.
8862 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
8864 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
8866 * data/glr.c (yyFail): Drastically simplify; since the format argument
8867 never had any % directives, we can simply pass it to yyerror.
8868 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
8869 be modified later, as that is the usual style in glr.c.
8870 Problems reported by Paul Hilfinger.
8872 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
8873 and size overflow errors.
8874 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
8875 in case the user prolog sets feature-test macros like _GNU_SOURCE.
8876 (YYSIZEMAX): New macro.
8877 (yystpcpy): New function, taken from yacc.c.
8878 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
8879 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
8880 so that we don't have to maintain their signatures.
8881 (yyFail): Check for buffer overflow, by using vsnprintf rather
8882 than vsprintf. Allocate a bigger buffer if possible.
8883 Report an error if buffer allocation fails.
8884 (yyStackOverflow): New function.
8885 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
8886 the initialization was successful. It might fail if storage was
8888 (yyexpandGLRStack): Add more checks for storage allocation failure.
8889 Use yyStackOverflow to report failures.
8890 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
8891 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
8892 Don't assume stack number fits in int.
8893 (yysplitStack): Check for storage allocation failure.
8894 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
8895 can print diagnostics on storage allocation failure. All callers
8897 (yyresolveValue): Use yybool for boolean.
8898 (yyreportSyntaxError): Check for size-calculation overflow.
8899 This code is taken from yacc.c.
8900 (yyparse): Check for storage allocation errors when allocating
8903 2005-07-05 Akim Demaille <akim@epita.fr>
8905 Extract calc++ from the documentation.
8906 * doc/bison.texinfo (Calc++): Add the extraction marks.
8907 * examples/extexi: New, from the aborted GNU Programming 2E.
8908 Separate the different paragraph of a file with empty lines.
8909 * examples/Makefile: Use it to extract the whole calc++ example.
8911 2005-06-24 Akim Demaille <akim@epita.fr>
8913 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
8916 2005-06-22 Akim Demaille <akim@epita.fr>
8918 * doc/bison.texinfo (C++ Language Interface): First stab.
8919 (C++ Parsers): Remove.
8921 2005-06-22 Akim Demaille <akim@epita.fr>
8923 * data/lalr1.cc (yylex_): Honor %lex-param.
8925 2005-06-22 Akim Demaille <akim@epita.fr>
8927 Start a set of simple examples.

8930 * examples/calc++/calc++-parser.yy,
8931 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
8932 * examples/calc++/compile, examples/calc++/test: New.
8934 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
8936 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
8937 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
8938 which stems from the 2005-05-27 patch.
8940 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
8942 * data/glr.c: Modify treatment of unused parameters to permit use
8943 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
8945 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
8947 Fix infringement on user name space reported by Janos Zoltan Szabo.
8948 * data/yacc.c (yyparse): strlen -> yystrlen.
8950 2005-05-30 Akim Demaille <akim@epita.fr>
8952 * data/lalr1.cc (_): New.
8953 Translate the various messages.
8955 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
8957 Fix infringement on user name space reported by Bruno Haible.
8958 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
8959 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
8960 the user's name space.
8961 (alloca): Include <stdlib.h> to get it, if it's not built in.
8962 (YYMALLOC, YYFREE): Define only if needed.
8963 (malloc, free): Declare, but only if needed, as this infringes on
8964 the user name space.
8966 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
8968 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
8969 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
8971 * lib/ebitset.c (min, max): Undef before defining.
8972 * lib/vbitset.c (min, max): Likewise.
8973 * lib/subpipe.c (create_subpipe): Save local variables in case
8974 vfork clobbers them.
8976 2005-05-24 Bruno Haible <bruno@clisp.org>
8978 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
8979 error message syntax used by gcc-4.0.
8981 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
8983 * README: Mention m4 1.4.3. Remove obsolete advice about
8984 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
8986 * bootstrap: Remove workaround for problem I encountered with
8987 gettext 0.14.1; it seems to be fixed now.
8989 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
8991 * NEWS: Version 2.0a.
8993 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
8994 the previous change.
8996 Various maintainer cleanups.
8997 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
8998 conftest*, for benefit of CVS commands run at the same time as
8999 "configure". Add build-aux, since "bootstrap" now creates it and
9001 * Makefile.cfg (move_if_change): Remove.
9002 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
9003 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

9008 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
9010 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
9011 this is now the recommended name.
9012 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
9013 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
9014 ylwrap. These files now go into build-aux.
9015 * config/move-if-change: Remove.
9016 * config/prev-version.txt: Bump from 1.75 to 2.0.
9018 * bootstrap: Add stdio-safer, unistd-safer modules.
9019 Remove m4/glibc2.m4 (introduced by latest gnulib, but

9022 fopen-safer.c, stdio-safer.h, unistd-safer.h.
9023 * lib/subpipe.c: Include "unistd-safer.h".
9024 (create_subpipe): Make sure all the newly-created
9025 file descriptors are > 2, so that diagnostics don't
9026 get sent down them (which might cause Bison to hang, in theory).
9027 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
9028 * src/files.c (xfopen): Use fopen_safer, not fopen.
9030 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
9031 yesterday's yacc.c fix.
9033 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>

9037 Fix a destructor bug reported by Wolfgang Spraul in
9038 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
9039 * data/yacc.c (yyabortlab): Don't call destructor, and
9040 don't set yychar to EMPTY.
9041 (yyoverflowlab): Don't call destructor.
9042 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
9043 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
9044 since we no longer output the message "discarding lookahead token
9047 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9049 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
9050 fix a small glitch in debugging output.
9051 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
9052 after YY_SYMBOL_PRINT where needed.
9054 (struct yyGLRState): Add some comments.
9055 (struct yySemanticOption): Add some comments.
9056 (union yyGLRStackItem): Add comment.
9058 (yymergeOptionSets): Correct this to properly perform the union,
9059 avoiding infinite reported by Michael Rosien.

9103 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
9105 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
9106 Problem reported by Ralf Menzel.
9108 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
9110 * tests/actions.at: Test that stack overflow invokes destructors.
9111 From Marcus Holland-Moritz.
9112 * data/yacc.c (yyerrlab): Move the code that destroys the stack
9114 (yyreturn): to here. That way, destructors are called properly
9115 even if the stack overflows, or the user calls YYACCEPT or
9116 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
9117 (yyoverflowlab): Destroy the lookahead.
9119 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
9121 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
9123 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
9125 * NEWS: Bison-generated C parsers no longer quote literal strings
9126 associated with tokens.
9127 * src/output.c (prepare_symbols): Don't escape strings,
9128 since users don't want to see C escapes.
9129 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
9131 * tests/input.at (Torturing the Scanner): Likewise.
9132 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
9134 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
9136 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
9137 the data size is known to be too small and we can't increase it.
9138 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
9140 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
9142 * src/parse-gram.y: Include quotearg.h.
9143 (string_as_id): Quote $1 before using it as a key, since the
9144 lexer no longer quotes it for us.
9145 (string_content): Don't strip quotes, since lexer no longer
9147 * src/scan-gram.l: Include quotearg.h.
9149 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
9150 a key, since the rest of the lexer doesn't quote it.
9151 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
9152 * tests/regression.at (Token definitions): Check for backslashes
9155 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
9156 (YYSIZE_T): Define to unsigned long int when using an older compiler.
9157 (yyparse): Revamp code to generate long syntax error message, to
9158 make it easier to translate, and to avoid problems with arithmetic
9159 overflow. Change "virtual memory" to "memory" in diagnostic, since
9160 we don't know whether the memory is virtual.
9162 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
9164 * NEWS: Bison-generated C parsers now use the _ macro to
9166 * data/yacc.c (_) [!defined _]: New macro.
9167 All English strings wrapped inside this macro.
9168 * doc/bison.texinfo (Bison Parser): Document _.
9169 * po/POTFILES.in: Include src/parse-gram.c, since it now
9170 includes translateable strings that parse-gram.y doesn't.
9172 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
9174 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
9175 reverting the 2004-10-11 change to this function.
9176 (symbol_check_alias_consistency): Don't call symbol_type_set
9177 if the type name is already correct.
9178 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
9180 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
9182 * tests/regression.at (Token definitions): Don't use a token named
9183 c, as that generates a "#define c ..." that runs afoul of buggy
9184 stdlib.h that uses the identifier c as a member of struct
9185 drand48_data. Problem reported by Horst Wente.
9187 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
9189 * bootstrap: Change translation URL from
9190 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
9191 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
9192 redirection glitches. Problem reported by twlevo@xs4all.nl.
9194 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
9196 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
9197 after operands; POSIX says this isn't portable for the c99 command.
9199 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
9201 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
9202 immediately if a data overrun has occurred; this may help us track
9203 down what may be a spurious failure on MacOS.
9205 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
9207 Respond to problems reported by twlevo@xs4all.nl.
9209 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
9211 * src/vcg.h: Comment fix.
9212 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
9213 (G_CMAX): Change to -1 instead of INT_MAX.
9215 * data/yacc.c (yyparse): Omit spaces before #line.
9217 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
9219 * src/tables.c (state_number_to_vector_number): Put it inside an
9220 "#if 0", since it's not currently used. Problem reported by
9223 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
9225 * src/output.c (escaped_output): Renamed from
9226 escaped_file_name_output, since we now use it for symbol tags as
9227 well. All uses changed.
9228 (symbol_destructors_output, symbol_printers_output):
9229 Escape symbol tags too.
9230 Problem reported by Matyas Forstner in
9231 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
9233 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
9235 * src/output.c (user_actions_output, token_definitions_output,
9236 symbol_destructors_output, symbol_printers_output): Likewise.
9237 * src/reader.c (prologue_augment): Likewise.
9238 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
9240 * src/vcg.c (output_edge): Don't quote linestyle arg.
9241 Problem reported by twlevo@xs4all.nl.
9243 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
9245 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
9246 example, reported by Derek M Jones. Also, make the example even
9247 more outrageous, to better illustrate how bad the problem is.
9249 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
9251 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
9252 putsym. Typo reported by Sebastian Piping.
9254 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
9256 * doc/bison.texinfo (Language and Grammar): some -> same
9257 (Epilogue): int he -> in the
9258 Typos reported by Sebastian Piping via Justin Pence.
9260 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
9262 * tests/glr-regression.at (Improper handling of embedded actions
9263 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
9264 embedded actions and $-N in GLR parsers", work around an Autoconf bug
9265 with dollar signs in test names.
9266 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
9267 for a similar reason.
9269 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9271 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
9272 wants to redefine G_VIEW.
9274 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
9276 * src/vcg.c (get_view_str): Remove case for normal_view.
9277 Problem reported by twlevo@xs4all.nl.
9279 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
9281 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
9282 Problem reported by twlevo@xs4all.nl.
9284 * doc/bison.texinfo: Change @dircategory from "GNU programming
9285 tools" to "Software development". Requested by Richard Stallman
9288 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
9290 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
9291 Problem reported by twlevo@xs4all.nl.
9293 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
9295 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
9296 keyword; it's not needed with modern compilers, and it doesn't
9297 affect correctness with older compilers. Suggested by
9300 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
9302 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
9303 gcc -Wswitch-default.
9304 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
9305 * data/yacc.c (yyparse): Likewise.
9307 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
9309 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
9310 already. Let config.h define any nonstandard values.
9312 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
9314 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
9315 for the benefit of slower hosts. Problem reported by
9318 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
9320 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
9321 being defined and not used.
9322 * data/lalr1.cc (yyparse): Likewise.
9323 Use "if (false)" rather than "if (0)".
9325 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
9327 * TODO: Mention that we should allow NUL bytes in tokens.
9329 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
9331 * src/scan-skel.l (<<EOF>>): Don't close standard output.
9332 Problem reported by Hans Aberg.
9334 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
9336 * src/getargs.c (version): Happy new year; update overall
9337 program copyright date from 2004 to 2005.
9339 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
9340 Problem reported by Hans Aberg.
9341 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
9342 (Output file names.): Add a test for the case when standard output
9345 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
9347 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
9348 to fix an oversight in the Bison 2.0 manual.
9350 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
9352 * NEWS: Version 2.0. Reformat the existing news items since
9353 1.875, so that related items are grouped together.
9354 * configure.ac (AC_INIT): Bump version to 2.0.
9355 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
9357 * tests/torture.at (Exploding the Stack Size with Alloca): Set
9358 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
9359 otherwise, we're not testing alloca. Unfortunately there's no
9360 simple way to consult HAVE_ALLOCA here.
9362 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
9365 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
9366 hand. This avoids a warning about comparing int to size_t when
9367 GCC warnings are enabled.
9369 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
9371 * NEWS: Bison-generated parsers no longer default to using the
9372 alloca function (when available) to extend the parser stack, due
9373 to widespread problems in unchecked stack-overflow detection.
9374 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
9375 responsibility to set it to a positive value. This lets the user
9376 specify a value that is not a preprocessor constant.
9377 * data/yacc.c (YYMAXDEPTH): Likewise.
9378 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
9379 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
9380 to be a compile-time constant. However, explain the constraints on it.
9381 Also, explain the constraints on YYINITDEPTH.
9382 (Table of Symbols): Explain that alloca is no longer the default.
9383 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
9386 * doc/bison.texinfo (Location Default Action): Mention that n must
9387 be zero when k is zero. Suggested by Frank Heckenbach.
9389 2004-12-22 Akim Demaille <akim@epita.fr>
9391 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
9392 (parser::state_type, parser::semantic_type, parser::location_type):
9393 Private, not public.
9394 (parser::parse): Return ints, not bool.
9395 Returning a bool introduces a problem: 0 corresponds to false, and
9396 it seems weird to return false on success. Returning true changes
9397 the conventions for yyparse.
9398 Alternatively we could return void and send an exception.
9399 There is no clear consensus (yet?).
9400 (state_stack, semantic_stack, location_stack): Rename as...
9401 (state_stack_type, semantic_stack_type, location_stack_type): these.
9402 Private, not public.
9403 * tests/c++.at: New.
9404 * tests/testsuite.at, tests/Makefile.am: Adjust.
9406 2004-12-21 Akim Demaille <akim@epita.fr>
9408 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
9410 2004-12-21 Akim Demaille <akim@epita.fr>
9412 Don't impose std::string for filenames.
9414 * data/lalr1.cc (b4_filename_type): New.
9415 (position::filename): Use it.
9416 (parser.hh): Move the inclusion of stack.hh and location.hh below
9417 the user code, so that needed headers for the filename type can be
9419 Forward declare them before the user code.
9420 * tests/Makefile.am (check-local, installcheck-local): Pass
9421 TESTSUITEFLAGS to the TESTSUITE.
9423 2004-12-20 Akim Demaille <akim@epita.fr>
9425 Use more STL like names: my_class instead of MyClass.
9427 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
9428 (SemanticStack, SemanticType, StateStack, StateType)
9429 (TokenNumberType, Stack, Slice, Traits, Parser::location)
9430 (Parser::value): Rename as...
9431 (location_stack, location_type, rhs_number_type, semantic_stack)
9432 (semantic_type, state_stack, state_type, token_number_type, stack)
9433 (slice, traits, parser::yylloc, parser::yylval): these.
9435 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
9437 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
9439 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
9440 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
9442 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
9444 Remove uses of 'short int' and 'unsigned short int'. This raises
9445 some arbitrary limits. It uses more memory but nowadays that's
9446 not much of an issue.
9448 This change does not affect the generated parsers; that's a different
9449 task, as some users will want to conserve memory there.
9451 Ideally we should use size_t to represent all object counts, and
9452 something like ptrdiff_t to represent signed differences of object
9453 counts; but that will require more code-cleanup than I have the
9454 time to do right now.
9456 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
9457 Use size_t, not int or short int, to count objects.
9458 * src/closure.c (nritemset, closure): Likewise.
9459 * src/closure.h (nritemset, closure): Likewise.
9460 * src/nullable.c (nullable_compute): Likewise.
9461 * src/print.c (print_core): Likewise.
9462 * src/print_graph.c (print_core): Likewise.

9467 * src/gram.h (rule_number, rule): Use int, not short int.
9468 * src/output.c (prepare_rules): Likewise.
9469 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
9470 errs, reductions): Likewise.
9471 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
9473 * src/tables.c (vector_number, tally, action_number,
9474 ACTION_NUMBER_MINIMUM): Likewise.
9475 * src/output.c (muscle_insert_short_int_table): Remove.
9477 2004-12-17 Akim Demaille <akim@epita.fr>
9479 * data/lalr1.cc: Extensive Doxygenation.
9480 (error_): Rename as...
9481 (error): this, since it is visible to the user.
9483 (Parser::message): Now an automatic variable from...
9484 (Parser::yyreport_syntax_error_): here.
9485 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
9487 * tests/input.at: Escape $.
9489 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
9491 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
9492 Parenthesize rhs to avoid obscure problems with mistakes like
9493 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
9494 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
9495 b4_rhs_location): Likewise.
9496 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
9497 b4_rhs_location): Likewise.
9499 2004-12-16 Akim Demaille <akim@epita.fr>
9501 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
9502 yacc.c: be sure to stay within yycheck_.
9503 * tests/actions.at: Re-enable C++ tests.
9505 2004-12-16 Akim Demaille <akim@epita.fr>
9507 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
9510 2004-12-16 Akim Demaille <akim@epita.fr>
9512 Use #define to handle the %name-prefix.
9514 * data/glr.c, data/yacc.c: Comment changes.
9515 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
9516 so that one can refer to yylex in the parser file, and have it
9517 renamed, as is the case with other skeletons.
9519 2004-12-16 Akim Demaille <akim@epita.fr>
9521 Move lalr1.cc internals into yy*.

9541 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
9543 Fix some problems reported by twlevo at xs4all.
9544 * src/symtab.c (symbol_new): Report an error if the input grammar
9545 contains too many symbols. This is better than calling abort() later.
9546 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
9547 (struct node, struct graph):
9548 Rename member expand to stretch. All uses changed.
9549 (struct graph): Remove member layoutalgorithm. All uses removed.

9555 2004-12-15 Akim Demaille <akim@epita.fr>
9557 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
9558 Add more Doxygen comments.
9559 (symprint_, stack_print_, reduce_print_, destruct_, pop)
9560 (report_syntax_error_, translate_): Rename as...
9561 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
9562 (yypop_, yyreport_syntax_error_, yytranslate_): this.
9564 2004-12-15 Akim Demaille <akim@epita.fr>
9566 * data/lalr1.cc (lex_): Rename as...
9568 Move the trace here.
9569 Take the %name-prefix into account.
9570 Reported by Alexandre Duret-Lutz.
9572 2004-12-15 Akim Demaille <akim@epita.fr>
9574 Simplify the C++ parser constructor.
9576 * data/lalr1.cc (debug_): Rename as...
9577 (yydebug_): so that the parser's internals are always in the yy*
9580 (b4_parse_param_decl): Remove the leading comma as it is now only
9581 called as unique argument list.
9582 (Parser::Parser): Remove the constructor accepting a location and
9583 an initial debugging level.
9584 Remove from the other ctor the argument for the debugging level.
9585 (debug_level_type, debug_level, set_debug_level): New.
9587 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
9590 2004-12-15 Akim Demaille <akim@epita.fr>
9592 Remove b4_root related material: failure experiment
9593 (which goal was to allow to derive from a class).
9595 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
9596 definitions and uses.
9598 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
9600 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
9601 not 2, since it's not portable to subtract 1 from the start of an
9602 array. The new item 0 is never set or used. All uses changed.
9604 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
9605 the default definition of YYLLOC_DEFAULT. Problem reported
9606 by Frank Heckenbach.
9608 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
9610 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
9611 the normal case and one for the error case. Just use the
9612 first one uniformly. Problem reported by Frank Heckenbach.
9613 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
9614 use exactly the same macro in both places.
9615 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
9616 so that the normal-case YYRHSLOC works for the error case too.
9618 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
9619 (YYLLOC_DEFAULT): Use the same macro as glr.c.
9620 * doc/bison.texinfo (Location Default Action): Don't claim that
9621 we have an array of locations. Use the same macro for both glr
9622 and lalr parsers. Mention YYRHSLOC. Mention what happens when
9625 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
9627 * HACKING: Update email addresses to send announcements to.
9629 * configure.ac (AC_INIT): Bump version to 1.875f.
9631 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
9633 * NEWS: Version 1.875e.
9634 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
9636 * src/scan-skel.l: Include "complain.h", for "fatal".
9638 * src/relation.h (relation_print, relation_digraph):
9639 Relation sizes are of type relation_node, not size_t (this is
9640 merely a doc fix, since the two types are equivalent).
9641 (relation_transpose): Relation sizes are of type relation_node,
9643 * src/relation.c: Likewise.
9644 (top, infinity): Now of type relation_node, not int.
9645 (traverse, relation_transpose): Use relation_node, not int.
9647 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
9648 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
9649 (yyparse): Remove unused local introduced in 2004-10-25 patch.
9651 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
9652 specifying whether the test should be skipped. Use it tp
9653 specify that the [%defines %skeleton "lalr1.cc"] tests currently
9654 fail on some hosts, and should be skipped.
9656 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
9658 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
9659 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
9660 unless otherwise specified below.
9662 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
9663 to allocate kernel_base, kernel_items, kernel_size, since
9664 they needn't be initialized to 0.
9665 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
9666 * src/closure.c (new_closure): Likewise, for itemset.
9667 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

9682 (goto_actions): Likewise for state_count.
9683 (pack_table): Likewise for base, pos, check.
9684 (tables_generate): Likewise for width.
9686 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
9687 for initial core. Just have a separate core, so we needn't worry
9688 about whether kernel_size and kernel_base are initialized.
9690 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
9691 kernel_size, kernel_items): Remove unnecessary initialization.

9697 conflrow, conflict_table, conflict_list, table, check):
9700 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
9701 This is because all callers pass unsigned int.
9702 * src/closure.h (new_closure): Likewise.
9704 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
9705 (build_relations): Initialize includes[i] in all cases.
9706 * src/reader.c (packgram): Always initialize rules[ruleno].prec
9707 and rules[ruleno].precsym. Initialize members in order.
9708 * src/relation.c (relation_transpose): Always initialize new_R[i]
9710 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
9712 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
9713 conflict_list[0] was always 0, but now it isn't initialized.
9715 * src/table.c (table_grow): When conflict_table grew, the grown
9716 area wasn't cleared. Fix this.
9718 * lib/.cvsignore: Add strdup.c, strdup.h.
9719 * m4/.cvsignore: Add strdup.m4.
9721 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
9723 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
9724 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
9725 GOTO_NUMBER_MAXIMUM, since we occasionally compute
9726 ngotos + 1 without checking for overflow.
9727 (build_relations): Use END_NODE, not -1, to denote end of edges.
9728 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
9729 build_relations): Use goto_number, not int, for goto numbers.
9730 * src/tables.c (save_column, default_goto): Likewise.
9732 2004-11-23 Akim Demaille <akim@epita.fr>
9734 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
9735 of #defining from yystype.
9736 Don't typedef yystype, C++ does not need it.
9737 This lets it possible to forward declare it as union.
9739 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
9741 * bootstrap (gnulib_modules): Add extensions.
9742 Problem reported by Jim Meyering.
9744 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
9746 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
9747 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
9748 src/system.h, src/tables.c: XFREE -> free, to accommodate
9749 recent change to gnulib xalloc.h.
9750 Problem reported by Jim Meyering.
9752 2004-11-17 Akim Demaille <akim@epita.fr>
9754 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
9756 2004-11-17 Akim Demaille <akim@epita.fr>,
9757 Alexandre Duret-Lutz <adl@gnu.org>
9759 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
9762 Use it instead of cdebug_.
9763 (Parser::debug_stream, Parser::set_debug_stream): New.
9764 (Parser::symprint_): Define cdebug_ for temporary backward
9766 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
9769 2004-11-17 Akim Demaille <akim@epita.fr>
9771 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
9772 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
9773 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
9774 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
9776 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
9778 * data/glr.c (yyloc_default): Remove; not used.
9779 Problem reported by Frank Heckenbach.
9781 2004-10-25 Akim Demaille <akim@epita.fr>
9783 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
9784 Introduce another definition to address simple location arrays.
9785 (yyGLRStack): New member: yyerror_range.
9786 (yyrecoverSyntaxError, yyparse): Update it.
9787 (yyrecoverSyntaxError): Use it when shifting the error token to
9788 have an accurate range, equivalent to the one computed by both
9789 yacc.c and lalr1.cc.
9790 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
9791 that column numbers start at column 0, as per GNU Coding
9792 Standards, the others tests, and the doc.
9793 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
9794 Adjust to the above change (first column is 0).
9795 And adjust the location of the "<error>", now covering the whole
9798 2004-10-22 Akim Demaille <akim@epita.fr>
9799 and Paul Eggert <eggert@cs.ucla.edu>
9801 Remove some arbitrary limits on goto numbers and relations.
9802 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
9803 initial values, since they're never used.
9804 (set_goto_map): ngotos is now unsigned, so test for overflow
9805 by seeing whether it wraps around to zero.
9806 * src/lalr.h (goto_number): Now size_t, not short int.
9807 (GOTO_NUMBER_MAXIMUM): Remove.
9808 * src/relation.c (relation_print, traverse, relation_transpose):
9809 Check for END_NODE rather than looking at sign.
9810 * src/relation.h (END_NODE): New macro.
9811 (relation_node): Now size_t, not short int.
9813 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
9815 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
9816 keyword, not an identifier. Problem reported by Baron Schwartz in
9817 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
9819 2004-10-11 Akim Demaille <akim@epita.fr>
9821 * src/symtab.c (symbol_check_alias_consistency): Also check
9822 type names, destructors, and printers.
9823 Reported by Alexandre Duret-Lutz.
9824 Recode the handling of associativity and precedence in terms
9825 of symbol_precedence_set.
9826 Accept no redeclaration at all, not even equal to the previous
9828 (redeclaration): New.
9829 Use it to factor redeclaration complaints.
9830 (symbol_make_alias): Don't set the type of the alias, let
9831 symbol_check_alias_consistency do it as for other features.
9832 * src/symtab.h (symbol): Add new member prec_location, and
9834 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
9835 * tests/input.at (Incompatible Aliases): New.
9837 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
9839 .cvsignore fixes to accommodate gnulib changes,
9840 and the practice of naming build directories "_build".
9841 * .cvsignore: Add "_*". Sort.
9842 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
9843 * m4/.cvsignore: Add "*_gl.m4".
9845 2004-10-06 Akim Demaille <akim@epita.fr>
9847 * src/parse-gram.y (add_param): Fix the truncation of trailing
9850 2004-10-05 Akim Demaille <akim@epita.fr>
9852 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
9853 whether the reducion was empty or not. This leaves room to
9854 improve the use of YYLLOC_DEFAULT in such a case.
9855 lalr1.cc is still experimental, so changing this is acceptable.
9856 And finally, there are probably not many users who changed the
9857 handling of locations in GLR, so changing is admissible too.
9859 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
9860 empty reduction, set @$ to an empty location ending the previously
9862 Adjust uses to make sure the code is triggered on empty
9864 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
9865 expected output: empty reductions have empty locations.
9867 2004-09-29 Akim Demaille <akim@epita.fr>
9869 * data/lalr1.cc: Move towards a more standard C++ coding style
9870 for templates: Class < T > -> Class<T>.
9872 2004-09-29 Akim Demaille <akim@epita.fr>
9874 * data/lalr1.cc: Reinstall the former ctor, for sake of
9875 compatibility, but warn it will be removed.
9876 Move towards a more standard C++ coding style (i.e., type *var ->
9879 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
9881 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
9882 since it's less likely to work if NULs are involved in the future.
9884 2004-09-27 Akim Demaille <akim@epita.fr>
9886 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
9888 2004-09-27 Akim Demaille <akim@epita.fr>
9890 * data/lalr1.cc (b4_parse_param_decl_1): New.
9891 (b4_parse_param_decl): Use it to have different names between attribute
9893 (b4_cc_constructor_call): Likewise.
9895 2004-09-24 Akim Demaille <akim@epita.fr>
9897 * src/parse-gram.y (add_param): Strip the leading and trailing
9898 blanks from a formal argument declaration.
9899 (YY_LOCATION_PRINT): New.
9901 2004-09-24 Akim Demaille <akim@epita.fr>
9903 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
9906 2004-09-24 Akim Demaille <akim@epita.fr>
9908 * doc/bison.texinfo (Table of Symbols): Sort.
9910 2004-09-21 Akim Demaille <akim@epita.fr>
9912 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
9913 the useless parentheses.
9914 Suggested by Paul Eggert.
9916 2004-09-20 Akim Demaille <akim@epita.fr>
9918 Let the initial-action act on the look-ahead, and use it for the
9919 "initial push" (corresponding to an hypothetical beginning-of-file).
9920 And let lalr1.cc honor %initial-action.
9922 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
9924 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
9925 (Parser::Parser): Remove the ctor that used to initialize it.
9926 (Parser::parse): Like in the other skeletons, issue the "starting
9927 parse" message before any action.
9928 Honor %initial-action.
9929 Initialize the stacks with the lookahead.
9930 * data/yacc.c: Let $$ and @$ in %initial-action designate the
9932 Push them in the stacks.
9933 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
9935 2004-09-20 Akim Demaille <akim@epita.fr>
9937 * doc/bison.texinfo (Initial Action Decl): New.
9939 2004-09-20 Akim Demaille <akim@epita.fr>
9941 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
9942 clearer criterion to define it.
9943 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
9944 When reducing on an empty RHS, use the latest stacked location as
9946 yylloc is not always available.
9947 * data/glr.c: Likewise.
9948 Also, honor initial-actions.
9950 2004-09-20 Akim Demaille <akim@epita.fr>
9952 * data/yacc.c (YY_LOCATION_PRINT): New.
9953 Define when we know YYLTYPE's structure, i.e., when the default
9954 YYLLOC_DEFAULT is used.
9955 * data/c.m4 (b4_yysymprint_generate): Use it.
9956 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
9957 value of the result.
9958 (error_start_): Replace with...
9959 (error_range_): this location array.
9960 This allows to replace code relying on the implementation of
9961 locations by portable code.
9962 * data/yacc.c (yylerrsp): Replace with...
9963 (yyerror_range): this.
9964 Every time a token is popped, update yyerror_range[0], to have an
9965 accurate location for the error token.
9966 * data/glr.c (YY_LOCATION_PRINT): New.
9967 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
9968 deference a pointer.
9969 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
9970 report the location in %printers.
9972 * src/scan-skel.l: Instead of abort, report error messages to ease
9973 understanding skeleton scanning failures.
9975 2004-09-16 Akim Demaille <akim@epita.fr>
9977 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
9978 (iterator, const_iterator): these, to be more in the C++ spirit.
9979 Also, return reverse iterators so that when displaying the stack
9980 we display its bottom first.
9981 (Parser::stack_print_, Parser::reduce_print_): Match the messages
9983 We should probably use vector here though.
9985 2004-09-16 Akim Demaille <akim@epita.fr>
9987 Have more complete shift traces.
9989 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
9990 to report Shifts instead of ad hoc YYDPRINTF invocations,
9991 including for the error token.
9992 * data/lalr1.cc (symprint_): Output the location.
9993 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
9994 output the location within the %printer.
9995 Activate GLR tests, at least to make sure they compile properly.
9996 They still don't pass though.
9997 * tests/calc.at: Adjust expect verbose output, since now "Entering
9998 state..." is on a different line than the "Shifting" message.
10000 2004-09-08 Akim Demaille <akim@epita.fr>
10002 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
10003 Bison directive from the Bison file to the invocation of this
10004 macro, so that these directives are passed to
10005 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10006 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10007 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10008 the extra Bison directives instead of the whole series.
10009 Change the grammar so that there are recoverable errors, and
10010 unrecoverable errors. Now we can have the parser give up before
10011 consuming the whole input. As a result we now can observe that
10012 the lookahead is freed when needed.
10013 Change the parser source to parse argv[1] instead of a hard coded
10015 Simplify yylex, and give a value and location to EOF.
10016 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10017 passed directives already coded in the file.
10018 Add some tests to check the location of "error".
10019 For some tests, the C++ parser is correct, and not yacc.c.
10020 For other tests, they provide different, but unsatisfying, values,
10021 so keep the C++ value so that at least one parser is "correct"
10022 according to the test suite.
10023 (Actions after errors): Remove, this is subsumed by the
10024 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
10026 2004-09-06 Akim Demaille <akim@epita.fr>
10028 * data/lalr1.cc: Adjust the indentation of the labels.
10029 (Parser::pop): New.
10032 2004-09-06 Akim Demaille <akim@epita.fr>
10034 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
10035 argument, an informative message.
10036 Call YY_SYMBOL_PRINT.
10037 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
10038 * data/lalr1.cc (destruct_): Likewise.
10039 In addition, no longer depend on b4_yysymprint_generate and
10040 b4_yydestruct_generate to generate these functions, do it "by
10043 2004-09-03 Akim Demaille <akim@epita.fr>
10045 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
10046 invoked, yydestruct the lookahead.
10047 * tests/calc.at (Calculator $1): Update the expected lengths of
10048 traces: there is an added line for the discarded lookahead.
10049 * doc/bison.texinfo (Destructor Decl): Some rewording.
10050 Define "discarded" symbols.
10052 2004-09-02 Akim Demaille <akim@epita.fr>
10054 * data/lalr1.cc (translate_, destruct_): No reason to be static.
10056 2004-09-02 Akim Demaille <akim@epita.fr>
10058 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
10059 (YYDSYMPRINTF): Rename as...
10060 (YY_SYMBOL_PRINT): this.
10061 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
10063 Use it instead of direct symprint_ calls.
10064 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
10067 2004-09-02 Akim Demaille <akim@epita.fr>
10069 * data/lalr1.cc (b4_yysymprint_generate): New.
10070 (symprint_): New member function, defined when YYDEBUG.
10071 Use it consistently instead of token/nterm debugging output by
10073 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
10074 %printer calls to use cdebug_ when using lalr1.cc.
10076 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
10078 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
10079 with #ifdef YYDEBUG.
10081 2004-08-26 Akim Demaille <akim@epita.fr>
10083 * doc/bison.texinfo (Implementing Loops): Rename as...
10084 (Implementing Gotos/Loops): this.
10086 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
10088 Adjust to latest gnulib.
10089 * bootstrap (gnulib_modules): Add xalloc-die.
10090 Set LC_ALL=C so that file names sort consistently.
10091 Prefer the gnulib copies of gettext.m4, glibc21.m4,
10092 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
10093 uintmax_t.m4, ulonglong.m4.
10094 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
10095 po.m4 since we are now using _gl.m4 instead.
10097 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
10099 * src/scan-action.l: Remove. Scanning of semantic actions is
10100 handled in scan-gram.l.
10102 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
10104 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
10106 * src/location.h (struct): The file member is a uniqstr.
10107 (equal_boundaries): Use UNIQSTR_EQ for comparison.
10109 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
10111 Fix bug with non-%union parsers that have printers or destructors,
10112 which led to a Bison core dump. Reported by Peter Fales in
10113 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
10115 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
10116 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
10117 not to our own type.
10118 * src/output.c (symbol_destructors_output, symbol_printers_output):
10119 Don't assume %union.
10120 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
10121 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
10122 UNION-FLAG. All callers changed.
10123 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
10124 Use type char, not unsigned int, when declaring an array of char;
10125 this lets us remove a cast.
10126 (Printers and Destructors): Add non-%union test cases.
10128 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10130 * doc/bison.texinfo: Minor editorial changes, mostly to the new
10131 GLR writeups. E.g., avoid frenchspacing and the future tense,
10132 change "lookahead" to "look-ahead", and change "wrt" to "with
10135 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10137 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
10138 New sections, split off from the GLR Parsers section. Put the new
10139 Simple GLR Parser near the start of the GLR section, for clarity.
10140 Rewrite connective text.
10142 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
10144 * doc/bison.texinfo (Simple GLR Parsers): New section.
10146 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10148 * NEWS, TODO, doc/bison.texinfo:
10149 Use "look-ahead" instead of "lookahead", to be consistent.

10160 * src/lalr.c (compute_look_ahead_tokens): Renamed from
10161 compute_lookaheads.
10162 (state_look_ahead_tokens_count): Renamed from state_lookaheads_count.
10163 (look_ahead_tokens_print): Renamed from lookaheads_print.
10164 * src/state.c (state_rule_look_ahead_tokens_print): Renamed from
10165 state_rule_lookaheads_print.
10166 * src/state.h: Likewise.
10167 (reductions.look_ahead_tokens): Renamed from lookaheads.
10168 * tests/torture.at (AT_DATA_LOOK_AHEAD_TOKENS_GRAMMAR): Renamed from
10169 AT_DATA_LOOKAHEADS_GRAMMAR.
10171 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
10173 * README: Update location of patched M4 distribution.
10175 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
10177 Don't assume the C++ compiler takes the same arguments as the C compiler
10179 * configure.ac (O0CXXFLAGS): New var.
10180 * tests/atlocal.in (CXXFLAGS): Use it.

10184 Fix some "make check" problems with C++ reported by
10185 Albert Chin-A-Young for Tru64 C++ in this thread:
10186 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
10188 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
10189 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10190 Output to a .cc file for C++, not to a .c file.
10191 * tests/calc.at (AT_CHECK_CALC): Likewise.
10192 * tests/regression.at (AT_CHECK_DANCER): Likewise.
10193 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
10195 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
10197 * tests/calc.at, tests/actions.at: Workaround for SGI
10198 C++ compiler. (trivial change)
10200 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
10202 Spent a few hours checking out which prerequisite versions the
10203 current sources actually require. I went all the way back to
10204 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
10205 a seemingly endless set of combinations of versions more recent
10206 than that. The bottom line is that the current sources require
10207 fairly recent versions of the build tools, and it'll be some work
10209 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
10210 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
10211 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
10212 Add comments explaining why those particular versions are
10215 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
10216 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
10217 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
10219 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
10220 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
10222 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
10224 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
10225 0.11.5. Suggested by Bruno Haible.
10226 * bootstrap: Remove gettext version checking.
10228 * doc/bison.texinfo (Decl Summary): Also mention that %union
10229 can depend on prerequisite types. Problem reported by Tim
10232 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
10234 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
10235 * README-alpha: Don't tell people not to package this.
10237 * bootstrap: Don't assume $(...) works; use `...` instead.
10238 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
10241 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
10242 put into the -d output file, and mention what to do if YYSTYPE is
10243 defined as a macro.
10245 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
10247 Undo change made earlier today: it caused autopoint to not bring
10248 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
10251 * bootstrap: Check that gettext version matches what's in
10252 configure.ac. Warn users to ignore robots.txt ERROR 404.
10253 * bootstrap: Undo today's earlier change (logged below).
10254 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
10256 The gettext version checking is causing more trouble than it's
10257 curing; remove it. Problem reported by Paul Hilfinger.
10259 * bootstrap: Issue a warning that one can expect a message
10260 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
10261 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
10263 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
10265 Ensure that the C++ compiler used for testing actually works on a
10266 simple test program; if not, skip the C++-related tests. Problem
10267 reported by Vin Shelton in:
10268 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
10270 * m4/cxx.m4: New file.

10272 * tests/atlocal.in (BISON_CXX_WORKS): Add.
10273 * tests/local.at (AT_COMPILE_CXX): Use it.
10275 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
10277 * data/glr.c (yylloc): Output this macro even if locations are not
10278 being generated, as the GLR parser needs it even in that case.
10279 Problem reported by Troy A. Johnson
10280 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
10282 * configure.ac (AC_INIT): Update to 1.875e.
10284 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
10286 * NEWS: Version 1.875d.
10287 * configure.ac (AC_INIT): Likewise.
10288 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
10290 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
10291 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
10292 lalr1.cc runs afoul of the first, and the last two are no longer
10293 supported by GCC 3.4.0.
10294 * README: Mention GNU m4 1.4 or later; mention m4 patches.
10295 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
10297 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
10299 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not

10310 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
10311 character and string literals.
10312 (unexpected_end): New function.
10313 (unexpected_eof): Use it.
10314 (unexpected_newline): New function.
10315 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
10318 * NEWS: Document %expect-rr.
10320 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
10321 Fix typo by replacing $1 with $option.
10322 Remove more 'intl'-related files.
10323 Don't DEFUN AM_INTL_SUBDIR twice.

10332 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
10333 * src/.cvsignore: Add *.output.
10335 * src/parse-gram.y: Put copyright notice inside %{ %} so it
10336 gets copied to the output file.
10338 2004-04-28 Paul Eggert <eggert@twinsun.com>
10340 Get files from the gnulib and po repositories, instead of relying
10341 on them being in our CVS. Upgrade to latest versions of gnulib
10344 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
10345 * bootstrap: Bootstrap from gnulib and po repositories.
10346 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
10347 * README-cvs: Document these changes. Remove version numbers from
10348 mentions of build tools, since they change so often. Mention Flex.
10350 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
10351 (gl_USE_SYSTEM_EXTENSIONS): Add.
10352 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
10353 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
10355 (AC_ISC_POSIX): Remove; we no longer support this
10356 ancient OS, as it gets in the way of latest Autoconf & gnulib.
10357 (AC_HEADER_STDC): Remove: we now assume C89 or better.
10358 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
10359 Do not check for C89 headers, except for locale.h which is used
10360 by the Yacc library and must port to K&R hosts.
10361 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
10362 Do not check for C89 functions, except for setlocale which is
10363 used by the Yacc library.
10364 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
10365 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

10368 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
10369 AM_GNU_GETTEXT): Remove; now done by:
10370 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
10371 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
10374 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
10375 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
10376 Define to empty, as gnulib.mk will do the rest for us.
10377 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
10379 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
10380 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
10382 * src/files.c: Include gnulib's xstrndup.h.
10384 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
10385 (REALLOC): Use xnrealloc, for likewise.
10386 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
10387 (strnlen, memrchr): Remove decls; functions no longer used.
10388 Include <stpcpy.h>.
10390 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

10410 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
10411 Remove, as these files are now generated automatically
10412 by bootstrap or automake.
10414 * po/ChangeLog: Remove: all but one entry was a duplicate
10415 of this file, and I moved that 2000-11-02 entry here.
10417 * config/.cvsignore: Add Makefile, depcomp, install-sh.
10418 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

10433 * po/.cvsignore: Add *.po, LINGUAS, Makefile.in.in, Makevars.
10434 * src/.cvsignore: Remove *_.c.
10437 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
10438 support it. (The latest stable gzip doesn't.)
10440 2004-04-27 Paul Eggert <eggert@twinsun.com>
10442 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
10443 case, as stos_ is now used by destructors due to the 2004-02-09
10446 Remove more K&R C support.
10447 * lib/libiberty.y (PARAMS): Remove. All uses removed.

10464 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
10465 with latest obstack.h.
10466 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
10467 to procedure types, as obstack.h now does that for us.
10468 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
10470 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
10471 so that this include file can stand alone.
10472 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
10473 does this now. Include subpipe.h first after config.h, to
10474 test whether it can stand alone.
10476 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
10477 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
10478 unused declaration.

10481 the union, because empty unions aren't allowed in C. Caught

10552 2004-03-08 Paul Eggert <eggert@gnu.org>
10554 Add support for hex token numbers. Suggested by Odd Arild Olsen in
10555 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.

10587 (Parser::parse) <yyerrlab1>: Compute the location of the error
10588 token so that it covers all the discarded tokens.
10589 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
10590 it can be called with `%skeleton "lalr1.cc"', and do that.
10592 2004-02-02 Paul Eggert <eggert@twinsun.com>
10594 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
10595 $(top_srcdir)/lib and ../lib. This fixes a bug reported
10596 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
10597 There's no need to mention top_builddir since Automake does that
10599 (INCLUDES): Remove, as Automake says it's obsolescent.
10600 Contents migrated into AM_CPPFLAGS as described above.
10601 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
10603 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10605 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
10606 (yyreportSyntaxError): Handle case where lookahead token is
10609 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10611 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
10612 resulting parsers are compilable with C++.
10614 2003-12-23 Paul Eggert <eggert@twinsun.com>
10616 * config/depcomp, config/install-sh: Sync with Automake 1.8.
10617 * src/output.c (output_skeleton): Rename local var.
10618 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
10619 Bison tokens, as this runs afoul of the 2003-10-07 change that
10620 disallowed NUL bytes in character constants or string literals.
10622 * tests/local.at: Require Autoconf 2.59's Autotest.
10623 * tests/testsuite.at: Don't include local.at, since we now assume
10624 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
10626 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
10627 multiple inclusion warnings.

10641 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
10642 if testsuite doesn't exist.

10647 Complain about NUL bytes in character constants or string literals.
10649 2003-10-05 Paul Eggert <eggert@twinsun.com>
10651 * NEWS: Don't document %no-default-prec, as it's still
10653 * doc/bison.texinfo: Document %no-default-prec only if

10656 2003-10-04 Paul Eggert <eggert@twinsun.com>
10658 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
10659 non-modifiable lvalue, instead of a modifiable one.
10660 * doc/bison.texinfo (Actions): Document that $$ can
10661 be assigned to. Do not claim that $$ and $N are
10662 array element references: user code should not rely on this.
10664 2003-10-01 Paul Eggert <eggert@twinsun.com>
10666 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.

10696 a typo in the 2003-08-25 patch.
10698 2003-08-27 Akim Demaille <akim@epita.fr>
10700 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify

10722 2003-08-25 Akim Demaille <akim@epita.fr>
10724 When reducing initial empty rules, Bison parser read an initial
10725 location that is not defined. This results in garbage, and that
10726 affects Bison's own parser. Therefore we need (i) to extend Bison
10727 to support a means to initialize this location, and (ii) to use
10728 this CVS Bison to fix CVS Bison's parser.
10730 * src/reader.h, reader.c (epilogue_augment): Remove, replace
10732 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
10733 * src/parse-gram.y: Adjust.
10734 (%initial-action): New.
10735 (%error-verbose): Since we require CVS Bison, there is no reason
10737 * src/scan-gram.l: Adjust.
10738 * src/Makefile.am (YACC): New, to make sure we use our own parser.
10739 * data/yacc.c (yyparse): Use b4_initial_action.
10741 2003-08-25 Akim Demaille <akim@epita.fr>
10743 * doc/bison.texinfo: Don't promote stdout for error messages.
10745 2003-08-25 Akim Demaille <akim@epita.fr>
10747 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
10748 From Alexandre Duret-Lutz.

10761 * data/lalr1.cc (Parser::reduce_print_): New.
10764 2003-08-25 Akim Demaille <akim@epita.fr>
10766 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
10767 error recovery loops. This patch is based on
10768 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
10769 Also, augment the similarity between lalr1.cc and yacc.c.
10770 Note: the locations of error recovery rules are not correct yet.
10772 * data/lalr1.cc: Comment changes to augment the similarity between
10773 lalr1.cc and yacc.c.
10774 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
10775 (yyerrlab1): Remove, but where it used to be (now the bottom part of
10776 yyerrlab), when hitting EOF, pop the whole stack here instead of
10777 merely falling thru the default error handling mechanism.
10778 (yyerrorlab): New label, with the old contents of YYERROR,
10779 plus the following change: pop the stack of rhs corresponding
10780 to the production that invoked YYERROR. That is how Yacc
10781 behaves (required by POSIX).
10782 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
10785 2003-08-25 Akim Demaille <akim@epita.fr>
10787 Tune local.at so that people can "autom4te -l autotest calc.at -o
10788 calc" for instance, to extract a sub test suite.
10790 * tests/testsuite.at: Move the initialization, Autotest version
10791 requirement, and AT_TESTED invocation into...
10792 * tests/local.at: here.
10793 * tests/testsuite.at: Include it for compatibility with Autoconf
10795 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
10798 2003-08-04 Paul Eggert <eggert@twinsun.com>
10800 Rework code slightly to avoid gcc -Wtraditional warnings.
10801 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
10802 The returned value is now stored in *YY0. All callers changed.
10803 * src/output.c (merge_output): Adjust to the above change.
10805 2003-07-26 Paul Eggert <eggert@twinsun.com>
10807 * data/glr.c (YYASSERT): New macro.
10808 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
10809 yyresolveStates, yyprocessOneStack):
10810 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
10811 Derived from a suggestion by Frank Heckenbach.
10813 2003-07-25 Paul Eggert <eggert@twinsun.com>
10815 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
10816 for portability to K&R C (after ansi2knr, presumably). See
10817 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
10818 by Frank Heckenbach, though I have omitted the structure-initialization
10819 part of his glr-knr.diff patch since I recall that the Portable
10820 C Compiler didn't require that change.
10822 Let the user specify how to allocate and free memory.
10823 Derived from a suggestion by Frank Heckenbach in
10824 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
10825 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
10826 All uses of free, malloc, realloc changed to use these macros,
10827 and unnecessary casts removed.
10828 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
10830 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
10832 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
10833 use s.empty() rather than s == "" to test for empty string; see
10834 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
10837 2003-06-25 Akim Demaille <akim@epita.fr>

10841 2003-06-20 Paul Eggert <eggert@twinsun.com>
10843 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
10844 and return properly parenthesized result.

10846 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10847 Remove unnecessary parentheses from uses.

10853 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
10854 yyreportTree): Do not assume that size_t is the same width as int,
10855 when printing sizes. Print sizes using an unsigned format.
10856 Problem reported by Frank Heckenbach in
10857 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
10859 Port to Forte Developer 7 C compiler.
10860 * data/glr.c (struct YYLTYPE): If locations are not being used,
10861 declare a single dummy member, as empty structs do not conform
10863 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
10864 the Forte Developer 7 C compiler complains that end-of-loop
10865 code is not reached.
10867 2003-06-17 Paul Eggert <eggert@twinsun.com>

10880 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
10881 Don't use 'index' in comments, as it's a builtin fn on some hosts.

10883 per recent gettext manual's suggestion.
10884 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
10885 Use prototypes, not old-style definitions.

10905 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
10906 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
10909 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
10910 `How Can I Reset @code{yyparse}', since texinfo does not allow
10911 arbitrary @ in node names.
10913 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
10914 shouldn't be needed according to the gettext 0.12.1 documentation
10915 but which seem to be needed anyway: codeset.m4 glibc21.m4
10916 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
10917 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

10923 Upgrade to CVS gnulib.
10924 * stdbool_.h: File renamed from stdbool.h.in.
10925 * configure.ac (AM_STDBOOL_H): Invoke this instead of

10938 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
10939 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
10940 the tests right now.
10941 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
10942 yyerror are declared before use; C99 requires this.
10944 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10946 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
10948 (yyrecoverSyntaxError): Correct the logic for setting and testing
10950 Correct comment on handling EOF.
10951 Allow states with only a default reduction, rather than failing
10952 (I can't quite reconstruct why these were not allowed before).
10954 Fixes to avoid problem that $-N rules in GLR parsers can cause
10955 buffer overruns, corrupting state.
10957 * src/output.c (prepare_rules): Output max_left_semantic_context
10959 * src/reader.h (max_left_semantic_context): New variable declaration.
10960 * src/scan-gram.l (max_left_semantic_context): Define.
10961 (handle_action_dollar): Update max_left_semantic_context.
10962 * data/glr.c (YYMAXLEFT): New definition.
10963 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
10964 (yyresolveAction): Ditto.
10966 Fixes to problems with location handling in GLR parsers reported by
10967 Frank Heckenbach (2003/06/05).
10969 * data/glr.c (YYLTYPE): Make trivial if locations not used.
10970 (YYRHSLOC): Add parentheses, and define only if locations used.
10971 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
10972 locations not used.

10974 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
10976 * tests/cxx-type.at: Exercise location information; update tests
10977 to differentiate output with and without locations.
10978 Remove forward declarations of yylex and yyerror---caused errors
10979 because default YYLTYPE not yet defined.
10980 Change semantic actions to compute strings, rather than printing
10981 them directly (to test proper passing of semantics values). Change
10982 output to prefix notation and update test data and expected results.
10983 (yylex): Track locations.
10984 (stmtMerge): Return value rather than printing, and include arguments
10987 2003-06-03 Paul Eggert <eggert@twinsun.com>
10989 Avoid warnings generated by GCC 2.95.4 when Bison is
10990 configured with --enable-gcc-warnings.
10991 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
10992 yy::]b4_parser_class_name[::translate_,
10993 yy::Stack::operator[] (unsigned),
10994 yy::Stack::operator[] (unsigned) const,
10995 yy::Slice::operator[] (unsigned),
10996 yy::Slice::operator[] (unsigned) const):
10997 Rename local vars to avoid warnings.
10998 * tests/glr-regression.at (Improper handling of embedded actions
10999 and $-N in GLR parsers): Remove unused local variable from yylex.
11000 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
11001 (void) as arg when not pure, since we now assume C89 when building
11002 Bison. Pacify GCC by using parameter.
11004 2003-06-02 Paul Eggert <eggert@twinsun.com>
11006 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
11007 yy::Location::lines, yy::Location::columns): Rename arguments
11008 to avoid shadowing; this removes a warning generated by GCC 3.3.
11010 2003-06-01 Paul Eggert <eggert@twinsun.com>
11012 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
11013 to g++, as GCC 3.3 complains if you do it.
11014 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
11015 everything that WARNING_CFLAGS has, except omit warnings
11016 not suitable for C++.
11017 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
11018 * tests/atlocal.in (CXXFLAGS): New var.
11019 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
11021 Fix a GLR parser bug I reported in February; see
11022 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
11023 The problem was that GLR parsers did not conform to the C standard,
11024 because actions like { $1 = $2 + $3; } expanded to expressions
11025 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11026 to a local variable. The C standard says that expressions
11027 like (var = f ()) + (var = f ()) have undefined behavior.
11028 Another problem was that GCC sometimes issues warnings that
11029 yyfill and its parameters are unused.
11031 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11032 as possibly unused.
11033 (yyfill): New function.
11035 (yyuserAction): Change type of yynormal to bool, so that it matches
11036 the new yyfill signature. Mark it as possibly unused.
11039 Follow up on a bug I reported in February, where a Bison-generated
11040 parser can loop. Provide a test case and a fix for yacc.c. I
11041 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11042 The original bug report is in:
11043 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
11045 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11046 macro's size was becoming unwieldy.
11047 (yyerrlab): Do not discard an empty lookahead symbol, as this
11048 might destroy garbage.
11049 (yyerrorlab): New label, with the old contents of YYERROR,
11050 plus the following change: pop the stack of rhs corresponding
11051 to the production that invoked YYERROR. That is how Yacc
11052 behaves, and POSIX requires this behavior.
11053 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11054 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11055 Define 'alarm' to do nothing if unistd.h is not available.
11056 Add a new rule "exp: '-' error;" to test the above change to
11057 data/yacc.c. Use 'alarm' to abort any test taking longer than
11058 10 seconds, as it's probably looping.
11059 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11060 Also, the new yacc.c generates two fewer diagnostics for an
11063 2003-05-24 Paul Eggert <eggert@twinsun.com>
11065 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
11066 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
11067 This fixes a problem reported by John Bowman when the Compaq/HP
11068 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
11069 -ansi -Wall -gall).
11070 * data/yacc.c (union yyalloc): Likewise.
11071 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
11073 Switch from 'int' to 'bool' where that makes sense.
11075 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
11076 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
11077 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
11078 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
11079 Return or accept bool, not int. All callers changed.
11080 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
11081 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.
11082 * lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_,
11083 bitset_copy_, bitset_op4_cmp, bitset_and_or_cmp_, bitset_andn_or_cmp_,
11084 bitset_or_and_cmp_): Likewise.
11085 * lib/bitset.h (bitset_test, bitset_only_set_p): Likewise.
11086 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,
11087 bitset_stats_test, bitset_stats_empty_p, bitset_stats_disjoint_p,
11088 bitset_stats_equal_p, bitset_stats_subset_p, bitset_stats_and_cmp,
11089 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
11090 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
11091 bitset_stats_or_and_cmp): Likewise.
11092 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
11093 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
11094 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
11095 ebitset_xor_cmp): Likewise.
11096 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
11097 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
11098 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
11099 lbitset_xor_cmp): Likewise.
11100 * lib/bbitset.h: Include <stdbool.h>.
11101 (struct bitset_vtable): The following members now return bool, not
11102 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
11103 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
11105 * src/conflicts.c (count_rr_conflicts): Likewise.
11106 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
11108 * lib/ebitset.c (ebitset_obstack_init): Likewise.
11109 * lib/lbitset.c (lbitset_obstack_init): Likewise.
11110 * src/getargs.c (debug_flag, defines_flag, locations_flag,
11111 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
11112 graph_flag): Likewise.
11113 * src/getargs.h (debug_flag, defines_flag, locations_flag,
11114 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
11115 graph_flag): Likewise.
11116 * src/output.c (error_verbose): Likewise.
11117 * src/output.h (error_verbose): Likewise.
11118 * src/reader.c (start_flag, typed): Likewise.
11119 * src/reader.h (typed): Likewise.

11121 (long_options, getargs): Use it.
11122 * src/lalr.c (build_relations): Use bool, not int.
11123 * src/nullable.c (nullable_compute): Likewise.
11124 * src/print.c (print_reductions): Likewise.
11125 * src/tables.c (action_row, pack_vector): Likewise.
11126 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
11127 * src/output.c (prepare): Use it.
11128 * src/output.c (token_definitions_output,
11129 symbol_destructors_output, symbol_destructors_output): Use string,
11130 not boolean integer, to keep track of whether to output separator.
11131 * src/print_graph.c (print_core): Likewise.
11132 * src/state.c (state_rule_lookaheads_print): Likewise.
11134 * config/install-sh: Sync from automake 1.7.5.
11136 2003-05-14 Paul Eggert <eggert@twinsun.com>
11138 * src/parse-gram.y (rules_or_grammar_declaration): Require a
11139 semicolon after a grammar declaration, in the interest of possible
11140 future changes to the Bison input language.
11141 Do not allow a stray semicolon at the start of the grammar.
11142 (rhses.1): Allow one or more semicolons after any rule, including
11143 just before "|" as required by POSIX.
11144 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
11147 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11149 %parse-param support for lalr1.cc.
11151 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
11152 b4_cc_constructor_calls, b4_cc_constructor_call,
11153 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
11155 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
11156 parse-param arguments.
11157 (yy::b4_parser_class_name): Declare instance variables to
11158 hold parse-param arguments.
11159 * tests/calc.at: s/value/semantic_value/ because value clashes
11160 with a member of yy::b4_parser_class_name. Adjust C++ code
11161 to handle %parse-param. Enable %parse-param test in C++.
11163 2003-05-12 Paul Eggert <eggert@twinsun.com>
11165 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
11166 English a bit. Fix fclose typo. Change "const char" to "char
11167 const", and use ANSI C rather than K&R for "main". Suggest
11168 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
11169 and suggest yy_switch_to_buffer.
11171 2003-05-05 Paul Eggert <eggert@twinsun.com>
11173 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
11174 C89. This avoids a diagnostic on compilers that define __STDC__
11175 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
11176 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11178 2003-05-03 Paul Eggert <eggert@twinsun.com>
11180 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
11181 Do not overrun array bounds.
11182 This should fix a bug reported today by Olatunji Oluwabukunmi in
11183 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
11185 2003-04-29 Akim Demaille <akim@epita.fr>
11187 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
11188 * src/getargs.c, src/getargs.h: here, as bool, not int.
11189 (nondeterministic_parser): New.
11190 * src/parse-gram.y, src/scan-gram.l: Support
11191 %nondeterministic-parser.
11192 * src/output.c (prepare): Use nondeterministic_parser instead
11193 of glr_parser where appropriate.
11194 * src/tables.c (conflict_row, action_row, save_row)
11195 (token_actions, token_actions, pack_vector): Ditto.
11197 2003-04-29 Akim Demaille <akim@epita.fr>
11199 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
11201 2003-04-29 Akim Demaille <akim@epita.fr>
11203 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
11204 with %pure-parser and %locations to exercise the patch from Yakov
11207 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
11209 * data/yacc.c: (b4_lex_param): Corrected for the case where
11210 %lex-param is provided and %pure-parser isn't.
11212 2003-04-27 Paul Eggert <eggert@twinsun.com>
11214 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
11215 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
11216 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
11217 if it is not defined.
11218 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
11220 2003-04-26 Paul Eggert <eggert@twinsun.com>
11222 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
11223 Declare to be of type suitable for the ninf value itself, not of
11224 type suitable for the corresponding table, since the latter might
11225 be unsigned but the ninf value might be negative. This fixes a
11226 bug reported by Alexandre Duret-Lutz in
11227 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
11229 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
11230 invokes it. We shouldn't invoke it twice because it will attempt
11231 to put error.o in the archive twice. This fixes a glitch reported
11232 by Martin Mokrejs in
11233 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11235 2003-04-21 Paul Eggert <eggert@twinsun.com>
11237 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
11240 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
11242 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
11243 Fix obvious typo that results in uncompilable GLR parsers
11244 when both %pure-parser and %locations are used. (trivial change)
11246 2003-04-17 Paul Eggert <eggert@twinsun.com>
11248 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
11249 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
11250 Do not insert the expected token via unput, as this runs afoul
11251 of a POSIX-compatibility bug in flex 2.5.31.
11252 All uses changed to BEGIN the parent state,
11253 since we no longer insert the expected token via unput.
11254 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
11255 that is no longer emitted after the above change.
11257 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
11258 the first one. This change is from Paul Hilfinger, and it fixes
11259 regression reported by Werner Lemberg in
11260 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
11262 (resolve_sr_conflict): Don't invoke state_errs_set
11263 unless one or more tokens have been explicitly made errors.
11264 Otherwise, the above change causes Bison to abort.
11266 * tests/existing.at (GNU pic Grammar): New test case, taken from
11269 2003-03-31 Akim Demaille <akim@epita.fr>
11271 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
11273 2003-03-31 Akim Demaille <akim@epita.fr>
11275 * src/output.c (prepare_symbols): Avoid trailing spaces in the
11278 2003-03-31 Akim Demaille <akim@epita.fr>
11280 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
11281 From Paul Hilfinger.
11283 2003-03-29 Akim Demaille <akim@epita.fr>
11285 * m4/error.m4: Do not put under dynamic conditions some code which
11286 expansion is under static control.
11288 2003-03-29 Akim Demaille <akim@epita.fr>
11290 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
11292 2003-03-29 Akim Demaille <akim@epita.fr>
11294 * doc/bison.texinfo (Strings are Destroyed): New.
11296 2003-03-13 Paul Eggert <eggert@twinsun.com>
11298 * .cvsignore: Add configure.lineno.
11299 * src/.cvsignore: Add yacc.
11300 * tests/.cvsignore: Add testsuite.log.
11301 * doc/fdl.texi: Sync with latest FSF version.
11303 2003-03-12 Paul Eggert <eggert@twinsun.com>
11305 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
11306 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
11307 cursor, instead of leaving it undefined. This fixes a bug
11308 reported by Tim Van Holder in
11309 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
11310 * tests/input.at (Torturing the Scanner): Test the scanner on
11311 an empty input file, which was Tim Van Holder's test case.
11313 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
11314 <sys/resource.h> can be included, include sys/time.h and
11315 sys/times.h first, if available. This works around the SunOS
11316 4.1.4 porting bug reported by Bruce Becker in
11317 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
11319 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
11320 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
11321 AC_HEADER_SYS_WAIT.
11323 Merge changes from gnulib. This was prompted because the CVS
11324 snapshot didn't build on Solaris 7 due to strnlen problems.
11326 These changes need to be merged back into gnulib:
11327 * lib/hash.c: Include <stdbool.h> unconditionally.
11328 * m4/onceonly.m4 (m4_quote): New macro.
11329 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
11330 Quote AC_FOREACH variable-expansions properly.
11331 The 2003-01-03 obstack.h change also needs merging.
11332 {end of changes requiring merging}
11334 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
11335 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
11336 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
11337 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
11338 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
11339 New files, imported from gnulib.
11340 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
11343 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
11344 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
11347 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
11349 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
11350 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
11351 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
11352 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
11353 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
11354 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
11355 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
11356 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
11357 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
11358 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
11359 (jm_PREREQ_ARGMATCH): Remove.
11360 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
11361 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
11363 * src/system.h: Include <stdbool.h> unconditionally.
11365 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
11366 assuming at least C89 in the bitset code for some time now.
11368 2003-03-03 Akim Demaille <akim@epita.fr>
11372 2003-03-02 Akim Demaille <akim@epita.fr>
11374 * doc/bison.texinfo (Table of Symbols): Reactivate the
11375 documentation for %lex-param, and %parse-param.
11377 2003-03-02 Akim Demaille <akim@epita.fr>
11379 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
11380 generate verbose error messages.
11381 Use the number of tokens as an upper bound in yytname, as it
11382 cannot be a non terminal.
11384 2003-03-02 Akim Demaille <akim@epita.fr>
11386 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
11389 2003-03-02 Akim Demaille <akim@epita.fr>
11391 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
11392 Use them to exercise yycheck overrun.
11393 Based on Andrew Suffield's grammar.
11395 2003-03-02 Akim Demaille <akim@epita.fr>
11397 Create tests/local.at for Bison generic testing macros.
11399 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
11400 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
11402 * tests/calc.at (AT_CHECK_CALC): Adjust.
11403 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
11404 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
11405 * tests/local.at: here.
11406 (AT_COMPILE_CXX): Tags the tests using it as c++.
11407 Ignore the test if CXX is not functional.
11409 2003-03-01 Paul Eggert <eggert@twinsun.com>
11411 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
11412 not loc->end, since loc->end might contain garbage and this leads
11413 to undefined behavior on some platforms.
11414 (id_loc, token_start): Use (IF_LINTed) initial values that do not
11415 depend on *loc, so that the reader doesn't give the the false
11416 impression that *loc is initialized.
11417 (<INITIAL>"%%"): Do not bother setting code_start, since its value
11418 does not survive the return.
11420 2003-03-01 Akim Demaille <akim@epita.fr>
11422 * src/scan-gram.l (code_start): Always initialize it when entering
11423 into yylex, as SC_EPILOGUE is activated *before* the corresponding
11424 yylex invocation. An alternative would be making it static, but
11425 then it starts with the second %%'s beginning, instead of its end.
11427 2003-02-28 Paul Eggert <eggert@twinsun.com>
11429 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
11430 around a UnixWare 7.1.1 porting bug reported by John Hughes in
11431 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
11433 2003-02-26 Paul Eggert <eggert@twinsun.com>
11435 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
11436 Remove Sequent/Pyramid discussion (nobody uses them any more).
11437 Merge VMS and MS-DOS discussion; these ports may well be dead
11438 but let's keep mentioning them for now. Put <> around email
11439 addresses. Add copyright notice.
11441 2003-02-24 Paul Eggert <eggert@twinsun.com>
11443 * data/glr.c (yy_reduce_print): yylineno -> yylno,
11444 to avoid collision with flex use of yylineno.
11445 Problem reported by Bruce Lilly in
11446 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

11450 * config/depcomp: Sync with Automake 1.7.3.
11452 2003-02-21 Akim Demaille <akim@epita.fr>
11454 * data/lalr1.cc: Use temporary variables instead of casts to
11455 change integer types.
11456 Suggested by Paul Eggert.
11458 2003-02-21 Akim Demaille <akim@epita.fr>
11460 * doc/bison.texinfo: Use "location" consistently to refer to @n,
11461 to avoid confusions with lalr1.cc's notion of Position.
11462 Suggested by Paul Eggert.
11464 2003-02-20 Akim Demaille <akim@epita.fr>
11466 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
11467 before initial_columns.
11468 (location.hh): Use consistent variable names when defining the
11470 Use "last" so that we subtract from Positions, not from unsigned.
11472 2003-02-20 Akim Demaille <akim@epita.fr>
11474 * data/lalr1.cc (position.hh): New subfile, including the extended
11475 and Doxygen'ed documentation of class Position.
11476 (location.hh): Use it.
11477 Document a` la Doxygen.
11478 With the help of Benoit Perrot.
11480 2003-02-20 Akim Demaille <akim@epita.fr>
11482 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
11484 Redefine AT_YYERROR_SEES_LOC_IF using it.
11485 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
11487 Don't use the location in yy::Parser::error_ and
11488 yy::Parser::print_ when not %locations.
11489 Activate more lalr1.cc tests.
11491 2003-02-19 Akim Demaille <akim@epita.fr>
11493 * data/lalr1.cc: When displaying a line number, be sure to make it
11496 2003-02-19 Akim Demaille <akim@epita.fr>
11498 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
11500 (YYABORT, YYACCEPT, YYERROR): New.
11501 * tests/calc.at: Renable the lalr1.cc test.
11503 2003-02-19 Akim Demaille <akim@epita.fr>
11505 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
11506 error recovery, mixing with/without pops and discarding of the
11509 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
11511 2003-02-17 Paul Eggert <eggert@twinsun.com>
11513 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
11514 * tests/testsuite.at (AT_COMPILE): Use them.
11515 This fixes the testsuite problem reported by Robert Lentz in
11516 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
11518 2003-02-12 Paul Eggert <eggert@twinsun.com>
11520 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
11521 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
11522 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
11523 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
11524 Check for malloc failure, for consistency with yacc.c.
11525 (yytname_size): Remove, for consistency with yacc.c.
11527 The bug still remains in data/lalr1.cc, as I didn't have time
11530 2003-02-06 Akim Demaille <akim@epita.fr>
11532 * configure.ac (GXX): Rename as...
11533 (CXX): this, to keep the original Autoconf semantics.
11535 * data/lalr1.cc: Fix b4_copyright invocations.
11536 If YYDEBUG is not defined, don't depend upon name_ being defined.
11537 (location.hh): Include string and iostream.
11538 (Position::filename): New member.
11539 (Position::Position ()): New.
11540 (operator<< (Position)): New.
11541 (operator- (Position, int)): New.
11542 (Location::first, Location::last): Rename as...
11543 (Location::begin, Location::end): these, to mock the conventional
11545 (operator<< (Location)): New.
11546 * tests/atlocal.in (CXX): New.
11547 * tests/testsuite.at (AT_COMPILE_CXX): New.
11548 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
11549 locations in a more synthetic way.
11550 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
11552 Adjust the C locations to match those from Emacs: first column is
11554 Change all the expected results.
11555 Conform to the GCS: simplify the locations when applicable.
11556 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
11557 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
11558 these CPP macros with the m4 macros new defined by...
11559 (AT_CHECK_PUSHDEFS): this, i.e.:
11560 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
11561 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
11563 (AT_CHECK_POPDEFS): Undefine them.
11564 (AT_CHECK_CALC_LALR1_CC): New.
11565 Use it for the first lalr1.cc test.
11567 2003-02-04 Akim Demaille <akim@epita.fr>
11569 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
11570 Location as is defined.
11572 2003-02-04 Akim Demaille <akim@epita.fr>
11574 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
11575 name_ being defined.
11577 2003-02-03 Paul Eggert <eggert@twinsun.com>
11579 * src/gram.h (start_symbol): Remove unused decl.
11581 Use more-consistent naming conventions for local vars.
11583 * src/derives.c (derives_compute): Change type of local var from
11584 int to rule_number.
11585 * src/gram.c (grammar_rules_partial_print): Likewise.
11586 * src/print.c (print_core): Likewise.
11587 * src/reduce.c (reduce_grammar_tables): Likewise.
11589 * src/gram.c (grammar_dump): Change name of item_number *
11590 local var from r to rp.
11591 * src/nullable.c (nullable_compute): Likewise.
11593 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
11595 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
11596 for symbol or symbol_number var.
11597 * src/reader.c (grammar_start_symbol_set): Likewise.
11598 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
11600 * src/state.c (transitions_to): Likewise.
11601 * src/state.h: Likewise.
11602 * src/tables.c (symbol_number_to_vector_number): Likewise.
11604 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
11607 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
11610 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
11613 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
11614 Use str, not s, for char * var. Use ch, not c, for character var.
11615 Use size for size var.
11617 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
11619 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
11621 * src/uniqstr.h: Likewise.
11623 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
11624 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
11625 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
11626 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
11627 param to have same name as that of enum, so that we don't use
11628 "s" to stand for a non-state.
11630 2003-02-02 Akim Demaille <akim@epita.fr>
11632 * src/scan-skel.l: Scan more than one inert character per yylex
11635 2003-02-01 Paul Eggert <eggert@twinsun.com>
11639 * po/LINGUAS: Add ms.
11641 2003-01-30 Akim Demaille <akim@epita.fr>
11643 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
11645 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11647 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
11650 Changes in response to error report by S. Eken: GLR mode does not
11651 handle negative $ indices or $ indices in embedded rules correctly.
11652 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
11654 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
11655 (b4_rhs_location): Ditto.
11656 (yyfill): New function to copy from stack tree into array
11658 (yyuserAction): Modify to allow incremental move of semantic values
11659 to rhs array when in GLR mode.
11660 Define YYFILL to use in user-defined actions to fill semantic array
11662 Remove dummy use of yystack, as there is now a guaranteed use.
11663 (yydoAction): Modify to allow incremental move of semantic values
11664 to rhs array when in GLR mode.
11665 (yyresolveAction): Ditto.
11666 (yyglrShiftDefer): Update comment.
11667 (yyresolveStates): Use X == NULL for pointers, not !X.
11668 (yyglrReduce): Ditto.
11669 (yydoAction): Ditto
11671 * tests/glr-regr1.at: Rename to ...
11672 * tests/glr-regression.at: Add new regression test for the problems
11673 described above (adapted from S. Eken).
11674 Update copyright notice.
11675 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
11676 * tests/Makefile.am: Ditto.
11678 2003-01-28 Paul Eggert <eggert@twinsun.com>
11680 * data/lalr1.cc: Do not use @output_header_name@ unless
11681 b4_defines_flag is set. This fixes two bugs reported by
11683 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
11684 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
11686 2003-01-21 Paul Eggert <eggert@twinsun.com>
11688 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
11689 we don't need to worry about yyerrlab1 being reported as an
11690 "unused label" by non-GCC C compilers. The downside is that if
11691 locations are used then a couple of statements are duplicated each
11692 time YYERROR is invoked, but the upside is that the warnings
11694 (yyerrlab1): Move code to YERROR.
11695 (yyerrlab2): Remove. Change uses back to yyerrlab1.
11696 This reverts some of the 2002-12-27 change.
11698 2003-01-17 Paul Eggert <eggert@twinsun.com>
11700 * src/output.c (symbol_printers_output): Fix typo that led
11701 to core dump. Problem reported by Antonio Rus in
11702 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
11704 2003-01-13 Akim Demaille <akim@epita.fr>,
11705 Quoc Peyrot <chojin@lrde.epita.fr>,
11706 Robert Anisko <anisko_r@lrde.epita.fr>
11708 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
11709 when the stacks contain one element, as the loop would otherwise
11710 free the last state, and then use the top state (the one we just
11711 popped). This means that the initial elements will not be freed
11712 explicitly, as is the case in yacc.c; it is not a problem, as
11713 these elements have fake values.
11715 2003-01-11 Paul Eggert <eggert@twinsun.com>
11717 * NEWS: %expect-violations are now just warnings, reverting
11718 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
11719 bootstrapping problem reported by Matthias Klose; see
11720 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
11721 * src/conflicts.c (conflicts_print): Likewise.
11722 * tests/conflicts.at (%expect not enough, %expect too much,
11723 %expect with reduce conflicts): Likewise.
11724 * doc/bison.texinfo (Expect Decl): Document this. Also mention
11725 that the warning is enabled if the number of conflicts changes
11726 (not necessarily increases).
11728 * src/getargs.c (version): Update copyright year.
11730 2003-01-09 Akim Demaille <akim@epita.fr>
11732 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
11734 2003-01-08 Paul Eggert <eggert@twinsun.com>
11736 * Makefile.maint (WGETFLAGS):
11737 New macro, containing "-C off" to disable proxy caches.
11738 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
11739 (rel-check): Use $(WGET) instead of wget.
11741 2003-01-06 Paul Eggert <eggert@twinsun.com>
11743 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
11744 the GLR paper of Scott, Johnstone and Hussain.
11746 2003-01-04 Paul Eggert <eggert@twinsun.com>
11748 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
11749 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
11750 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
11751 (EXTRA_LIBRARIES): New var, for liby.a.
11752 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
11753 (EXTRA_SCRIPTS): New var, for yacc.
11755 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
11756 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
11757 Problem reported by Nelson H. F. Beebe.
11759 2003-01-03 Paul Eggert <eggert@twinsun.com>
11761 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
11762 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
11763 when compiling Bison 1.875's `bitset bset = obstack_alloc
11764 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
11766 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
11767 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
11768 grow to a huge size with typical invocation.
11770 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
11771 Use the pattern recommended by Autoconf 2.57, except also protect
11772 against double-definition.
11773 * src/system.h: Likewise.
11774 Portability issues reported by Nelson H. F. Beebe.
11776 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
11777 All uses changed. Provide a definition in both C and C++.
11778 (yytrue, yyfalse): Define even if defined (__cplusplus).
11780 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
11781 Reported by Nelson H. F. Beebe.
11783 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
11785 2003-01-02 Paul Eggert <eggert@twinsun.com>
11787 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
11788 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
11789 Bug reported by Nelson H. F. Beebe.
11791 2003-01-01 Paul Eggert <eggert@twinsun.com>
11795 2002-12-30 Paul Eggert <eggert@twinsun.com>
11797 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
11799 (<INITIAL>","): Here. This causes stray "," to be treated
11802 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
11803 last brace in braced code when not in Yacc mode, for compatibility
11804 with Bison 1.35. This resurrects the 2001-12-15 patch to
11807 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
11808 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
11810 2002-12-28 Paul Eggert <eggert@twinsun.com>
11812 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
11813 that of SYM's type. This fixes Debian bug 168069, reported by
11816 2002-12-28 Paul Eggert <eggert@twinsun.com>
11820 Switch back to the Yacc style of conflict reports, undoing some
11821 of the 2002-07-30 change.
11822 * doc/bison.texinfo (Understanding): Use Yacc style for
11823 conflict reports. Also, use new way of locating rules.
11824 * src/conflicts.c (conflict_report):
11825 Renamed from conflict_report_yacc, removing the old
11826 'conflict_report'. Translate the entire conflict report at once,
11827 so that we don't assume that "," has the same interpretation in
11829 (conflicts_output): Use Yacc-style conflict report for each state,
11830 instead of our more-complicated style.
11831 (conflicts_print): Use Yacc-style conflict report, except print
11832 the input file name when not emulating Yacc.
11833 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
11834 Conflicted Reduction, %expect not enough, %expect too much,
11835 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
11836 * tests/existing.at (GNU Cim Grammar): Likewise.
11837 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
11839 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
11840 fatal): Don't invoke fflush; it's not needed and it might even be
11841 harmful for stdout, as stdout might not be open.
11842 * src/reduce.c (reduce_print): Likewise.
11844 2002-12-27 Paul Eggert <eggert@twinsun.com>
11846 Fix a bug where error locations were not being recorded correctly.
11847 This problem was originally reported by Paul Hilfinger in
11848 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
11850 * data/yacc.c (yyparse): New local var yylerrsp, to record the
11851 top of the location stack's error locations.
11852 (yyerrlab): Set it. When discarding a token, push its location
11853 onto yylerrsp so that we don't lose track of the error's end.
11854 (yyerrlab1): Now is only the target of YYERROR, so that we can
11855 properly record the location of the action that failed. For GCC
11856 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
11857 GCC warning about yyerrlab1 being unused if YYERROR is unused.
11858 (yyerrlab2): New label, which yyerrlab now falls through to.
11859 Compute the error's location by applying YYLLOC_DEFAULT to
11860 the locations of all the symbols that went into the error.
11861 * doc/bison.texinfo (Location Default Action): Mention that
11862 YYLLOC_DEFAULT is also invoked for syntax errors.
11863 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
11864 Error locations include the locations of all the tokens that were
11865 discarded, not just the last token.
11867 2002-12-26 Paul Eggert <eggert@twinsun.com>
11869 * src/files.c: Include quote.h.
11870 (compute_output_file_names): Warn if we detect conflicting
11871 outputs to the same file. This should catch the misunderstanding
11872 exemplified by Debian Bug 165349, reported by Bruce Stephens..
11874 * src/conflicts.c (conflicts_print): If the user specifies
11875 "%expect N", report an error if there are any reduce/reduce
11876 conflicts. This is what the manual says should happen.
11877 This fixes Debian bug 130890, reported by Anthony DeRobertis.
11878 * tests/conflicts.at (%expect with reduce conflicts): New test.
11880 Don't use m4_include on relative file names, as it doesn't work as
11881 desired if there happens to be a file with that name under ".".
11883 * m4sugar/version.m4: Remove; it was included but it wasn't used.
11884 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
11885 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
11886 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
11887 * src/output.c (output_skeleton): Use full path names when
11888 specifying a file to include; don't rely on include path, as
11889 it's unreliable when the working file contains a file with
11892 2002-12-25 Paul Eggert <eggert@twinsun.com>
11894 Remove obsolete references to bison.simple and bison.hairy.
11895 Problem mentioned by Aubin Mahe in
11896 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
11897 * data/glr.c: Comment fix.
11898 * doc/bison.1: Remove references. Also, mention "yacc".
11900 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
11903 * src/parse-gram.y (declaration): Use enum "report_states" rather
11904 than its numeric value 1.
11906 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
11907 opening a new one. This fixes Debian bug 165349, reported by
11910 2002-12-24 Paul Eggert <eggert@twinsun.com>
11914 * Makefile.maint (cvs-update): Don't assume that the shell
11915 supports $(...), as Solaris sh doesn't.
11917 * src/parse-gram.y (lloc_default): Remove test for empty
11918 nonterminals at the end, since it didn't change the result.
11920 2002-12-24 Paul Eggert <eggert@twinsun.com>
11922 If the user does not define YYSTYPE as a macro, Bison now declares it
11923 using typedef instead of defining it as a macro. POSIX requires this.
11924 For consistency, YYLTYPE is also declared instead of defined.
11926 %union directives can now have a tag before the `{', e.g., the
11927 directive `%union foo {...}' now generates the C code
11928 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
11929 The default union tag is `YYSTYPE', for compatibility with Solaris 9
11930 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
11931 instead of `yyltype'.
11933 `yystype' and `yyltype' are now obsolescent macros instead of being
11934 typedefs or tags; they are no longer documented and will be
11935 withdrawn in a future release.
11937 * data/glr.c (b4_location_type): Remove.
11938 (YYSTYPE): Renamed from yystype.
11939 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
11940 (struct YYLTYPE): Renamed from struct yyltype.
11941 (YYLTYPE): Renamed from yyltype.
11942 (yyltype, yystype): New (and obsolescent) macros,
11943 for backward compatibility.
11944 * data/yacc.c: Likewise.
11946 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
11947 does not specify a union tag. This is for compatibility with
11950 * src/parse-gram.y (add_param): 2nd arg is now char * not char
11951 const *, since it is now modified by stripping surrounding { }.
11952 (current_braced_code): Remove.
11953 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
11954 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
11955 trailing " {...}". Now of type <chars>.
11956 (grammar_declaration): Adjust to bundled tokens.
11957 (code_content): Remove; stripping is now done by add_param.
11958 (print_token_value): Print contents of bundled tokens.
11959 (token_name): New function.
11961 * src/reader.h (braced_code, current_braced_code): Remove.
11962 (token_name): New decl.
11964 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
11965 token_type, not braced_code code_kind. All uses changed.
11966 (SC_PRE_CODE): New state, for scanning after a keyword that
11967 has (or usually has) an immediately-following braced code.
11968 (token_type): New local var, to keep track of which token type
11969 to return when scanning braced code.
11970 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
11971 <INITIAL>"%parse-param", <INITIAL>"%printer",
11972 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
11973 instead of returning a token type immediately.
11974 (<INITIAL>"{"): Set token type.
11975 (<SC_BRACED_CODE>"}"): Use it.
11976 (handle_action_dollar, handle_action_at): Now returns bool
11977 indicating success. Fail if ! current_rule; this prevents a core dump.
11978 (handle_symbol_code_dollar, handle_symbol_code_at):
11979 Remove; merge body into caller.
11980 (handle_dollar, handle_at): Complain in invalid contexts.
11982 * NEWS, doc/bison.texinfo: Document the above.
11983 * NEWS: Fix years and program names in copyright notice.
11985 2002-12-17 Paul Eggert <eggert@twinsun.com>
11987 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
11988 Reporting, Table of Symbols): Omit mentions of %lex-param and
11989 %parse-param from the documentation for now.
11991 2002-12-15 Paul Eggert <eggert@twinsun.com>
11993 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
11994 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
11995 lookahead symbol, and which sets yychar in parser actions) and it
11996 disagreed with the Bison documentation. Bug
11997 reported by Andrew Walrond.
11999 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
12000 as the caller now does that.
12001 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
12002 (YYEMPTY): Parenthesize right hand side, since others use it.
12003 (yyparse): Don't assume that our generated code is the only code
12006 2002-12-13 Paul Eggert <eggert@twinsun.com>
12010 POSIX requires a "yacc" command.
12011 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
12012 (MOSTLYCLEANFILES): Add yacc.
12014 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
12015 as an alias for bison y.
12017 * po/LINGUAS: Add da.
12019 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
12020 problem with latest <getopt.h>.
12021 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
12023 * doc/fdl.texi: Upgrade to 1.2.
12024 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
12025 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
12026 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
12028 * config/install-sh: Sync with autotools.
12030 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
12031 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12032 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
12033 locations are requested.
12034 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
12035 locations are requested.
12037 2002-12-12 Paul Eggert <eggert@twinsun.com>
12039 Remove unportable casts and storage allocation tricks.
12040 While we're at it, remove almost all casts, since they
12041 usually aren't needed and are a sign of trouble.
12043 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
12045 * src/derives.c (derives_compute): Do not subtract NTOKENS from
12046 the pointer DSET returned by malloc; this isn't portable.
12047 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
12048 Similarly for DERIVES.
12049 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
12050 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
12051 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
12053 * src/derives.c (derives_compute): Do not bother invoking
12054 int_of_rule_number, since rule numbers are integers.
12056 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
12057 rather than XMALLOC (char, N).
12059 * src/files.c (filename_split): Rewrite to avoid cast.
12061 * src/gram.h (symbol_number_as_item_number,
12062 item_number_as_symbol_number, rule_number_as_item_number,

12067 symbol_number_to_vector_number): Likewise.
12069 * src/gram.h (int_of_rule_number): Remove; no longer used.
12071 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
12072 since the resulting storage is always stored into.
12074 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
12077 * src/muscle_tab.c (muscle_m4_output):
12078 Now inline. Return bool, not int.
12079 * src/state.c (state_compare): Likewise.
12080 * src/symtab.c (symbol_check_defined,
12081 symbol_check_alias_consistency, symbol_pack, symbol_translation,

12089 symbol_check_alias_consistency_processor, symbol_pack_processor,
12090 symbol_translation_processor, hash_symbol_comparator,
12091 hash_symbol_hasher): Likewise.
12092 * src/uniqstr.c (uniqstr_print_processor): Likewise.
12093 * src/muscle_tab.c (muscles_m4_output):
12094 Use new functions instead of casting old functions unportably.
12095 * src/state.c (state_hash_new): Likewise.
12096 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
12097 symbols_token_translations_init):
12099 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
12101 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
12102 var instead of casting to long, to avoid casts.
12103 (prepare_states): Use MALLOC rather than alloca, so that we don't
12104 have to worry about alloca.
12105 * src/state.c (state_hash_lookup): Likewise.
12107 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
12108 local var instead of casting to unsigned char, to avoid casts.
12110 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
12111 STATE_ALLOC): Remove.
12112 (transitions_new, errs_new, reductions_new, state_new): Use malloc
12113 rather than calloc, and use offsetof to avoid allocating slightly
12115 (state_new): Initialize all members.
12117 * src/state.c (state_hash): Use unsigned accumulator, not signed.
12119 * src/symtab.c (symbol_free): Remove; unused.

12122 hashing-related ones.
12124 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
12125 (symbol_processor): Remove.
12126 (symbols_do): Remove decl; now static.
12128 * src/system.h (alloca): Remove; decl no longer needed.
12129 (<stddef.h>): Include, for offsetof.
12130 (<inttypes.>, <stdint.h>): Include if available.
12131 (uintptr_t): New type, if system lacks it.
12132 (CALLOC, MALLOC, REALLOC): New macros.
12133 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
12136 * src/tables.c (table_size): Now int, to pacify GCC.
12137 (table_grow, table_ninf_remap): Use signed table size.
12138 (save_row): Don't bother initializing locals when not needed.

12149 2002-12-09 Paul Eggert <eggert@twinsun.com>
12151 Change identifier spellings to avoid collisions with names
12152 that are reserved by POSIX.
12154 Don't use names ending in _t, since POSIX reserves them.
12155 For consistency, remove _e and _s endings -- they're weren't
12156 needed to remove ambiguity. All uses changed.
12157 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
12158 turn was just renamed from struniq_t.
12159 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
12160 which in turn was just renamed from struniq_processor_t.
12161 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

12232 value_t_as_yystype -> value_as_yystype.
12234 Don't include <errno.h> in the mainstream code, since it
12235 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
12236 * lib/get-errno.c, lib/get-errno.h: New files.
12237 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

12247 (TAB_EXT): Renamed from EXT_TAB.

12250 Avoid str[a-z]*, since <string.h> reserves that name space.
12251 Change all instances of "struniq" in names to "uniqstr", and
12252 likewise for "STRUNIQ" and "UNIQSTR".
12253 * src/uniqstr.c: Renamed from src/struniq.c.
12254 * src/uniqstr.h: Renamed from src/struniq.h.

12265 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
12266 (N_EXPAND): Renamed from N_STRETCH.

12276 (BASE_MAXIMUM): Renamed from BASE_MAX.
12277 (BASE_MINIMUM): Renamed from BASE_MIN.
12278 (ACTION_MAX): Remove; unused.
12279 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.

12290 for consistency with other names.
12291 * lib/timevar.h (timevar_report): New decl.
12292 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
12295 Sort include-file uses.
12297 Reorder all include files under src to be in the order "system.h".
12298 then the ../lib include files in angle brackets (alphabetized),
12299 then the . include files in double-quotes (alphabetized). Fix
12300 dependency breakages encountered in this process, as follows:
12301 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
12302 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
12303 * src/state.h: Include "symtab.h".
12305 2002-12-08 Paul Eggert <eggert@twinsun.com>
12307 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
12308 since this causes problems when __file__ contains character
12309 sequences like "@" that are treated specially by src/scan-skel.l.
12310 Instead, just use the file's basename. This fixes the bug
12311 reported by Martin Mokrejs in
12312 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
12314 2002-12-06 Paul Eggert <eggert@twinsun.com>
12316 Add support for rules that do not have trailing semicolons, as

12324 * src/location.h: Do not include <quotearg.h>; no longer needed.
12325 (boundary): New type.
12326 (location_t): Use it. This allows locations to span file boundaries.

12334 (location_print): New decl.
12335 * src/parse-gram.y (lloc_default): New function, which handles

12347 * src/reader.h: Include location.h.
12348 (scanner_cursor): New decl.
12349 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
12351 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
12353 (STEP): Remove. No longer needed, now that adjust_location does
12354 the work. All uses removed.
12355 (scanner_cursor): New var.
12356 (adjust_location): Renamed from extend_location. It now sets
12357 *loc and adjusts the scanner cursor. All uses changed.
12358 Don't bother testing for CR.
12359 (handle_syncline): Remove location arg; now updates scanner cursor.
12360 All callers changed.
12361 (unexpected_end_of_file): Now accepts start boundary of token or
12362 comment, not location. All callers changed. Update scanner cursor,
12364 (SC_AFTER_IDENTIFIER): New state.
12365 (context_state): Renamed from c_context. All uses changed.
12366 (id_loc, code_start, token_start): New local vars.
12367 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
12368 processing of Yacc white space and equivalents here.
12369 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
12370 instead of returning ID immediately, since we need to search for
12371 a subsequent colon.
12372 (<INITIAL>"'", "\""): Save token_start.
12373 (<INITIAL>"%{", "{", "%%"): Save code_start.
12374 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
12375 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
12376 BEGIN context_state at end, not INITIAL.
12377 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
12378 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
12379 Return correct token start.
12380 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
12381 the start of a character, string or multiline comment is found.
12382 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
12383 Reduction): Adjust reported locations to match the more-precise
12384 results now expected.
12385 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
12386 * tests/reduce.at (Useless Rules, Reduced Automaton,
12387 Underivable Rules): Likewise.
12388 * tests/regression.at (Invalid inputs): No longer `expecting ";"
12389 or "|"' now that so many other tokens are allowed by the new grammar.
12391 * src/complain.h (current_file): Remove duplicate decl;
12392 current_file is now owned by files.h.
12393 * src/complain.c, src/scan-gram.l: Include files.h.
12395 2002-12-06 Paul Eggert <eggert@twinsun.com>
12397 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
12398 promotes to int; it might be unsigned int.
12399 * data/yacc.c (yy_reduce_print): Likewise.
12401 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
12402 be #defined in the prologue, not in the Bison declarations.
12403 This fixes Debian Bug 102878, reported by Shaul Karl.
12405 2002-12-02 Paul Eggert <eggert@twinsun.com>
12407 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
12408 * lib/strtoul.c: New file, from gnulib.
12409 This fixes a porting bug reported by Peter Klein in
12410 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
12412 2002-11-30 Paul Eggert <eggert@twinsun.com>
12414 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
12415 and put only a forward declaration in the prologue. This is for
12416 consistency with the other scanner helper functions.
12418 Type clashes now generate warnings, not errors, since it
12419 appears that POSIX may allow some grammars with type clashes.
12420 * src/reader.c (grammar_current_rule_check): Warn about
12421 type clashes instead of complaining.
12422 * tests/input.at (Type Clashes): Expect warnings, not complaints.
12424 Add Yacc library, since POSIX requires it.
12425 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
12426 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
12427 * lib/main.c, lib/yyerror.c: New files.
12429 gram_error can be static; it need not be extern.
12430 * src/reader.h (gram_error): Remove decl.
12431 * src/parse-gram.y (gram_error): Now static. Add static decl.
12432 (print_token_value): Omit parameter names from forward decl,
12435 2002-11-29 Paul Eggert <eggert@twinsun.com>
12437 * doc/bison.texinfo: Emphasize that yylex and yyerror must
12438 be declared before being used. E.g., one should typically
12439 declare them in the prologue. Use GNU coding style in examples.
12440 Put "const" consistently after the type it modifies. Mention
12441 that C99 supports "inline". Mention that yyerror traditionally
12444 %parse-param and %lex-param now take just one argument, the
12445 declaration; the argument name is deduced from the declaration.
12447 * doc/bison.texinfo (Parser Function, Pure Calling, Error
12448 Reporting, Table of Symbols): Document this.
12449 * src/parse-gram.y (add_param): New function.
12451 (declaration): Implement new rule for %parse-param and %lex-param.
12452 * src/scan-gram.l: "," now elicits a warning, rather than being
12453 a token; this is more compatible with byacc.
12454 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
12456 2002-11-27 Paul Eggert <eggert@twinsun.com>
12458 Rename identifiers to avoid real and potential collisions.
12460 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
12461 to avoid collision with lex macro described by Bruce Lilly in
12462 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12463 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
12464 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
12465 * src/parse-gram.y (print_token_value): Renamed from yyprint.
12467 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
12468 The name "yycontrol" violates the name space rules, and this stuff
12469 wasn't being used anyway.
12470 (input): Remove action; this stuff wasn't being used.
12471 (gram_error): Rename local variable yylloc -> loc.
12472 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
12473 (YY_DECL): Don't use "yy" at start of local variables.
12474 All uses changed, e.g., yylloc -> loc.
12475 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
12476 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
12477 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
12478 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
12480 * src/parse-gram.y (gram_error): loc is now const *.
12481 * src/reader.h (gram_error): Likewise.
12483 2002-11-24 Paul Eggert <eggert@twinsun.com>
12487 * tests/actions.at (Actions after errors): Use an output format
12488 more similar to that of the Printers and Destructors test.
12489 Test the position of the ';' token too.
12490 (Printers and Destructors): Likewise.
12491 (Printers and Destructors: %glr-parser): Remove for now, to avoid
12492 unnecessarily alarming people when the test fails.
12494 * data/yacc.c (yyerrlab1): Move this label down, so that the
12495 parser does not discard the lookahead token if the user code
12496 invokes YYERROR. This change is required for POSIX conformance.
12498 * lib/error.c: Sync with gnulib.
12500 2002-11-22 Paul Eggert <eggert@twinsun.com>
12502 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
12503 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
12504 * lib/xmalloc.c: Likewise.
12506 2002-11-20 Paul Eggert <eggert@twinsun.com>
12508 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
12510 2002-11-20 Paul Eggert <eggert@twinsun.com>
12512 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
12513 should use `if (! x) abort ();' rather than `assert (x);', and
12514 anyway it's one less thing to worry about configuring.
12516 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
12517 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
12518 and replace all instances of assert with abort.
12519 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
12520 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
12522 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
12523 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
12524 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
12525 hash_find_entry, hash_rehash, hash_insert): Likewise.
12526 * src/conflicts.c (resolve_sr_conflict): Likewise.
12527 * src/lalr.c (set_goto_map, map_goto): Likewise.
12528 * src/nullable.c (nullable_compute): Likewise.
12529 * src/output.c (prepare_rules, token_definitions_output): Likewise.
12530 * src/reader.c (packgram, reader): Likewise.
12531 * src/state.c (state_new, state_free, state_transitions_set,
12532 state_reduction_find): Likewise.
12533 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
12534 symbol_pack): Likewise.
12535 * src/tables.c (conflict_row, pack_vector): Likewise.
12536 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
12537 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
12538 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
12539 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
12541 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
12542 (ARGMATCH_CONSTRAINT): New macro.
12543 (ARGMATCH_ASSERT): Use it.
12545 * src/system.h (verify): New macro.
12546 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
12547 rather than assert.
12548 * src/tables.c (tables_generate): Likewise.
12550 * src/struniq.c (struniq_assert): Now returns void, and aborts
12551 if the assertion is false.
12552 (struniq_assert_p): Remove.
12553 * src/struniq.h: Likewise.
12555 2002-11-18 Paul Eggert <eggert@twinsun.com>
12557 * data/glr.c (yygetLRActions): Replace `yyindex' with
12558 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
12559 This fixes the regression with Sun ONE Studio 7 cc that I reported in
12560 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
12562 2002-11-18 Akim Demaille <akim@epita.fr>
12564 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
12566 From Tim Van Holder.
12568 2002-11-17 Paul Eggert <eggert@twinsun.com>
12570 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
12571 to "SyntaxError" for consistency with my 2002-11-15 change.
12573 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
12574 not define to {}, since this breaks the common use of `YYDPRINTF
12575 ((...));' if a single statement is desired (e.g. before `else').
12576 Work around GCC warnings by surrounding corresponding calls with
12578 (yyhasResolvedValue): Remove unused function.
12579 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
12581 (yyreportSyntaxError): Renamed from yyreportParseError.
12582 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
12584 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
12585 extern when possible. Remove unused initializations.
12587 2002-11-16 Akim Demaille <akim@epita.fr>
12589 Augment the similarity between GLR and LALR traces.
12591 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
12592 (YY_REDUCE_PRINT): New.
12593 (yyparse): Use them.
12594 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
12596 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
12597 state reached after the reduction/recovery, since...
12598 (yyparse, yyprocessOneStack): Report the state we are entering in.
12600 2002-11-16 Akim Demaille <akim@epita.fr>
12602 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
12603 Add support for --trace=skeleton.
12604 * src/scan-skel.l: %option debug.
12605 Scan strings of non-@ or \n instead of character by character.
12606 (scan_skel): Handle trace_skeleton.
12608 (@output_parser_name@, @output_header_name@): ``Restore'' their
12609 support (used to be M4 macros).
12610 * data/yacc.c: Quote larger chunks, a la glr.c.
12611 * data/lalr1.cc: Likewise.
12612 The header guards are no longer available, so use some other
12613 string than `YYLSP_NEEDED'.
12615 2002-11-16 Akim Demaille <akim@epita.fr>
12617 Make the ``Printers and Destructors'' test more verbose, taking
12618 `yacc.c''s behavior as (possibly wrong) reference.
12620 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
12621 instead of fprint on stdout.
12622 Set and report the last_line of the symbols.
12623 Consistently display values and locations.
12625 2002-11-16 Paul Eggert <eggert@twinsun.com>
12627 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
12629 2002-11-15 Paul Eggert <eggert@twinsun.com>
12631 * tests/actions.at (Actions after errors): New test case.
12633 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
12634 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
12635 tests/action.at, tests/calc.at, tests/conflicts.at,
12636 tests/cxx-type.at, tests/regression.at:
12637 "parse error" -> "syntax error" for POSIX compatibility.
12638 "parsing stack overflow..." -> "parser stack overflow" so
12639 that code matches Bison documentation.
12641 2002-11-15 Akim Demaille <akim@epita.fr>
12643 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
12644 take two BRACED_CODE, not two string_content.
12645 Free the scanner's obstack when we are done.
12646 (code_content): New.
12647 * tests/calc.at: Adjust.
12648 * doc/bison.texinfo: Adjust.
12649 Also, make sure to include the `,' for these declarations.
12651 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
12653 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
12654 definition; avoids potential autoreconf problems.
12656 2002-11-15 Akim Demaille <akim@epita.fr>
12658 Always check the value returned by yyparse.
12660 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
12661 returned by yyparse.
12662 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
12664 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
12665 returned by yyparse.
12667 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12669 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
12672 2002-11-14 Paul Eggert <eggert@twinsun.com>
12674 * src/output.c (output_skeleton): Call xfopen instead of
12675 duplicating xfopen's body.
12677 Fix bugs reported by Nelson H. F. Beebe in
12678 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
12680 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
12681 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
12682 Group compiler. Instead, use "$CC -E bar.c". Include the .h
12683 file twice in the grammar, as an extra check.
12685 * tests/input.at (Torturing the Scanner): Surround the
12686 backslash-newline tests with "#if 0", to make it less likely that
12687 we'll run into compiler bugs. Bring back solitary \ inside
12688 comment, but add a closing comment to work around HP C bug. Don't
12689 test backslash-newline in C character constant.
12691 2002-11-14 Akim Demaille <akim@epita.fr>
12693 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
12694 status of the compiler.
12695 Calling `exit 1' is no longer needed.
12696 Reported by Nelson H. F. Beebe.
12698 2002-11-14 Akim Demaille <akim@epita.fr>
12700 * tests/atlocal.in (CPPFLAGS): We have config.h.
12701 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
12703 * tests/actions.at, tests/calc.at, tests/conflicts.at,
12704 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
12705 * tests/regression.at, tests/torture.at: Use them for all the
12706 grammars that are to be compiled.
12707 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
12708 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
12709 * doc/bison.texinfo (GLR Parsers): Document `inline'.
12711 2002-11-14 Akim Demaille <akim@epita.fr>
12713 * doc/bison.texinfo: Various formatting changes (alignments in
12714 samples, additional @group/@end group, GCS in samples.
12715 Use @deffn instead of simple @table to define the directives,
12716 macros, variables etc.
12718 2002-11-13 Paul Eggert <eggert@twinsun.com>
12720 Fix some bugs reported by Albert Chin-A-Young in
12721 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
12723 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
12724 -o c"; the HP C compiler chatters during compilation.
12725 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
12726 * tests/headers.at (export YYLTYPE): Likewise.
12728 * tests/input.at (Torturing the Scanner): Remove lines containing
12729 solitary backslashes, as they tickle a bug in the HP C compiler.
12731 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
12732 comments, since they're not portable. Use GNU coding style.
12734 2002-11-13 Akim Demaille <akim@epita.fr>
12736 * data/yacc.c: Leave bigger chunks of quoted text.
12737 (YYDSYMPRINTF): New.
12738 Use it to report symbol activities.
12739 * data/glr.c (YYDSYMPRINTF): New.
12742 2002-11-12 Paul Eggert <eggert@twinsun.com>
12746 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
12747 (yyglrReduce): Return yyok, not 0.
12748 This should avoid the enumerated-type warnings reported
12749 by Nelson H. F. Beebe in
12750 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
12752 * lib/bbitset.h (BITSET_INLINE): Remove.
12753 * lib/bitset.h [! BITSET_INLINE]: Remove.
12754 (bitset_set, bitset_reset, bitset_test): Rename local vars
12755 to avoid shadowing warnings by GCC.
12757 * data/glr.c (inline): Remove #define. It's the user's
12758 responsibility to #define it away, just like 'const'.
12759 This fixes one of the bugs reported by Nelson H. F. Beebe in
12760 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
12762 * Makefile.maint (po-check): Scan .l and .y files instead of the
12763 .c and the .h files that they generate. This fixes the bug
12764 reported by Tim Van Holder in:
12765 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
12766 Look for N_ as well as for _. Try to avoid matching #define for
12768 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
12769 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
12770 * src/scan-gram.l: Revamp regular expressions so that " and '
12771 do not confuse xgettext.
12773 * src/struniq.h (struniq_new): Do not declare the return type
12774 to be 'const'; this violates the C standard.
12775 * src/struniq.c (struniq_new): Likewise.
12777 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
12779 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
12780 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
12783 2002-11-12 Akim Demaille <akim@epita.fr>
12785 * Makefile.maint: Sync with Autoconf:
12786 (local_updates): New.
12788 2002-11-12 Akim Demaille <akim@epita.fr>
12790 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
12792 2002-11-12 Akim Demaille <akim@epita.fr>
12794 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the

12923 Revamp to fix many (but not all) of the C- and M4-related quoting
12924 problems. Among other things, this fixes the Bison bug reported
12925 by Jan Hubicka when processing the Bash grammar; see:
12926 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
12928 Use new @ escapes consistently. Represent brackets with @{ and @}
12929 rather than @<:@ and @:>@, since this works a bit better with dumb
12930 editors like vi. Represent @ with @@, since @ is now consistently
12931 an escape. Use @oline@ and @ofile@ rather than __oline__ and
12932 __ofile__, to avoid unexpected expansions. Similarly, use @output
12933 rather than #output.
12935 * data/c.m4 (b4_copyright): Omit file name from comment, since
12936 the file name could contain "*/".
12937 (b4_synclines_flag): Don't quote the 2nd argument; it should already
12938 be quoted. All uses changed.
12940 * data/glr.c: Use new @ escapes consistently.
12941 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
12942 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
12943 Remove, since they couldn't handle arbitrary characters in file
12945 * data/lalr1.cc: Likewise.
12946 * data/yacc.c: Likewise.
12948 * src/files.c (output_infix): Remove; all uses removed.
12949 * src/files.h: Likewise.
12951 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
12952 mishandled funny characters in file names, and anyway it isn't
12954 * data/yacc.c: Likewise.
12955 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
12957 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
12958 * data/yacc.c: Likewise.
12960 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
12962 (muscle_init): Quote filename as a C string.
12963 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
12964 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
12965 * src/output.c (escaped_file_name_output): New function.
12966 (prepare_symbols): Quote tokens for M4.
12967 (prepare): Don't insert output_infix, output_prefix,
12968 output_parser_name, output_header_name; this is now down by scan-skel.
12969 Insert skeleton as a C string.
12971 * src/output.c (user_actions_output, symbol_destructors_output,
12972 symbol_printers_output): Quote filenames for C and M4.
12973 * src/reader.c (prologue_augment, epilogue_set): Likewise.
12975 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
12976 escapes other than \\ and \'; this simplifies the code.
12977 (<SC_STRING>): Likewise, for \\ and \".
12978 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
12979 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
12980 Use new escapes @{ and @} for [ and ].
12982 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
12983 them with auto vars.
12984 Switch to new escape scheme, where @ is the escape character uniformly.
12985 Abort if a stray escape character is found. Avoid unbounded input
12986 buffer when parsing non-escaped text.
12988 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
12989 __oline__, #output, $@, and @{ do not have unintended meanings.
12991 2002-11-09 Paul Eggert <eggert@twinsun.com>
12993 Fix the test failure due to GCC warnings described in
12994 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
12995 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
12996 evaluate to 0 if it's impossible for NINF to be in the respective
12998 (yygetLRActions, yyrecoverParseError): Use them.
13000 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
13001 counted in the token inserted at end of file. Now takes
13002 location_t *, not location_t, so that the location can be
13003 adjusted. All uses changed.
13005 * tests/regression.at (Invalid inputs): Adjust wording in
13006 diagnostic to match the new behavior.
13008 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
13009 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
13010 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
13011 abort ();'. This reduces the runtime of the "Many lookaheads"
13012 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
13015 2002-11-07 Paul Eggert <eggert@twinsun.com>
13017 * src/parse-gram.y (CHARACTER): Remove unused token.
13020 * src/scan-gram.l: Remove stack option. We no longer use the
13021 stack, since the stack was never deeper than 1; instead, use the
13022 new auto var c_context to record the stacked value.
13024 Remove nounput option. At an unexpected end of file, we now unput
13025 the minimal input necessary to end cleanly; this simplifies the
13028 Avoid unbounded token sizes where this is easy.
13030 (unexpected_end_of_file): New function.
13031 Use it to systematize the error message on unexpected EOF.
13032 (last-string): Now auto, not static.
13033 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
13034 (scanner_last_string_free): Remove; not used.
13035 (percent_percent_count): Move decl to just before use.
13036 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
13037 not the (never otherwised-used) CHARACTER.
13039 2002-11-07 Akim Demaille <akim@epita.fr>

13262 * src/system.h (errno): Remove declaration, as we are now
13263 assuming C89 or better, and C89 guarantees errno.
13265 2002-10-30 Paul Eggert <eggert@twinsun.com>
13267 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
13268 Check for close failures.
13269 * src/files.h (xfclose): Return void, not int, since it always
13271 * src/files.c (xfclose): Likewise. Report I/O error if ferror
13273 * src/output.c (output_skeleton): Use xfclose rather than fclose
13274 and ferror. xfclose now checks ferror.
13276 * data/glr.c (YYLEFTMOST_STATE): Remove.
13277 (yyreportTree): Use a stack-based leftmost state. This avoids
13278 our continuing battles with bogus warnings about initializers.
13280 2002-10-30 Akim Demaille <akim@epita.fr>
13282 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
13285 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13287 * tests/glr-regr1.at: New test for reported regressions.
13288 * tests/testsuite.at: Add glr-regr1.at test.
13289 * tests/Makefile.am: Add glr-regr1.at test.
13291 2002-10-24 Paul Eggert <eggert@twinsun.com>
13295 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
13296 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
13297 we use malloc. Don't assume 'A' through 'Z' are contiguous.
13298 Don't assume strdup exists; POSIX says its an XSI extension.
13299 Check for buffer overflow on input.
13301 2002-10-24 Akim Demaille <akim@epita.fr>
13303 * src/output.c (output_skeleton): Don't disable M4sugar comments
13304 too soon: it results in comments being expanded.
13305 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
13308 2002-10-24 Akim Demaille <akim@epita.fr>
13310 * data/yacc.c (m4_int_type): New.
13311 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
13312 char' as only yacc.c wants K&R portability.
13313 * data/glr.c (yysigned_char): Remove.
13314 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
13315 Reported by Quoc Peyrot.
13317 2002-10-23 Paul Eggert <eggert@twinsun.com>
13319 * src/main.c (main): With --trace=time, report times even if a
13320 non-fatal error occurs. Formerly, the times were reported in some
13321 such cases but not in others.
13322 * src/reader.c (reader): Just return if a complaint has been issued,
13323 instead of exiting, so that 'main' can report times.
13325 2002-10-22 Akim Demaille <akim@epita.fr>
13327 * src/system.h: Include sys/types.
13328 Reported by Bert Deknuydt.
13330 2002-10-23 Paul Eggert <eggert@twinsun.com>
13332 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
13333 Suggested by Art Haas.
13335 2002-10-22 Paul Eggert <eggert@twinsun.com>
13337 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
13338 decl; not needed any more.
13339 * src/main.c (main): Use return to exit, undoing yesterday's change.
13340 The last OS that we could find where this wouldn't work is
13341 SunOS 3.5, and that's too old to worry about now.
13343 * data/glr.c (struct yyltype): Define members even when not
13344 doing locations. This is more consistent with yacc.c, and it
13345 works around the following bug reports:
13346 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
13347 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
13349 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
13350 @acronym consistently. Standardize on "Yacc" instead of "YACC",
13351 "Algol" instead of "ALGOL". Give a bit more history about BNF.
13353 2002-10-22 Akim Demaille <akim@epita.fr>
13355 * data/README: New.
13357 2002-10-21 Paul Eggert <eggert@twinsun.com>
13359 Be consistent about 'bool'; the old code used an enum in one
13360 module and an int in another, and this violates the C standard.
13361 * m4/stdbool.m4: New file, from coreutils 4.5.3.
13362 * configure.ac (AC_HEADER_STDBOOL): Add.
13363 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
13364 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
13365 * src/symtab.c (hash_compare_symbol_t): Likewise.
13366 * src/system.h (bool, false, true): Use a definition consistent
13367 with ../lib/hash.c. All uses changed.
13369 * src/complain.c (warning_issued): Renamed from warn_message_count,
13370 so that we needn't worry about integer overflow (!).
13371 Now of type bool. All uses changed.
13372 (complaint_issued): Renamed from complain_message_count; likewise.
13374 * src/main.c (main): Use exit to exit with failure.
13376 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
13377 rather than 1 and 0.
13378 * src/main.c (main): Likewise.
13379 * src/getargs.c (getargs): Likewise.
13380 * src/reader.c (reader): Likewise.
13382 * src/getarg.c (getargs): Remove duplicate code for
13383 "Try `bison --help'".
13385 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
13386 What was that "2" for?
13388 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
13389 * src/getargs.c (usage): Likewise.
13391 * src/getargs.c (getargs): When there are too few operands, report
13392 the last one. When there are too many, report the first extra
13393 one. This is how diffutils does it.
13395 2002-10-20 Paul Eggert <eggert@twinsun.com>
13397 Remove K&R vestiges.
13398 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
13399 * src/complain.c (VA_START): Remove. Assume prototypes.
13400 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
13401 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
13402 fatal): Assume prototypes.
13403 * src/complain.h: Assume prototypes.
13404 * src/system.h (PARAMS): Remove.
13405 Include <limits.h> unconditionally, since it's guaranteeed even
13406 for a freestanding C89 compiler.
13407 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
13408 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
13410 2002-10-20 Akim Demaille <akim@epita.fr>
13412 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
13413 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
13414 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
13415 (yyresolveStates, yyresolveAction, yyresolveStack)
13416 (yyprocessOneStack): Use them.
13417 (yy_reduce_print): New.
13418 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
13420 2002-10-20 Akim Demaille <akim@epita.fr>
13422 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
13423 arguments and output `void'.
13424 (b4_c_function): Rename as...
13425 (b4_c_function_def): this.
13426 (b4_c_function_decl, b4_c_ansi_function_def)
13427 (b4_c_ansi_function_decl): New.
13428 Change the interpretation of the arguments: before `int, foo', now
13430 * data/yacc.c (yyparse): Prototype and define thanks to these.
13431 Adjust b4_c_function_def uses.
13432 * data/glr.c (yyparse): Likewise, but ANSI only.
13434 2002-10-20 Akim Demaille <akim@epita.fr>
13436 * src/output.c (prepare): Move the definition of `tokens_number',
13437 `nterms_number', `undef_token_number', `user_token_number_max'
13439 (prepare_tokens): Here.
13440 (prepare_tokens): Rename as...
13441 (prepare_symbols): this.
13442 (prepare): Move the definition of `rules_number' to...
13443 (prepare_rules): here.
13444 (prepare): Move the definition of `last', `final_state_number',
13445 `states_number' to...
13446 (prepare_states): here.
13447 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
13449 2002-10-20 Akim Demaille <akim@epita.fr>
13451 * src/tables.h, src/tables.c, src/output.c: Comment changes.
13453 2002-10-20 Akim Demaille <akim@epita.fr>
13455 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
13458 2002-10-20 Akim Demaille <akim@epita.fr>
13460 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
13461 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
13463 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
13465 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
13466 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
13469 2002-10-19 Paul Eggert <eggert@twinsun.com>
13471 Do not create a temporary file, as that involves security and
13472 cleanup headaches. Instead, use a pair of pipes.
13473 Derived from a suggestion by Florian Krohm.
13474 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
13475 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
13476 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
13477 (BISON_PREREQ_SUBPIPE): Add.
13478 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
13479 Add subpipe.h, subpipe.c.
13480 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
13481 * po/POTFILES.in: Add lib/subpipe.c.
13482 * src/output.c: Include "subpipe.h".
13483 (m4_invoke): Remove decl.
13484 (scan_skel): New decl.
13485 (output_skeleton): Use pipe rather than temporary file for m4 input.
13486 Check that m4sugar.m4 is readable, to avoid deadlock.
13487 Check for pipe I/O error.
13488 * src/scan-skel.l (readpipe): Remove decl.
13489 (scan_skel): New function, to be used in place of m4_invoke.
13490 Read from stream rather than file.
13492 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
13493 float, as this generates a warning on Solaris 8 + GCC 3.2 with
13494 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
13495 this generates a more-accurate value anyway.
13497 * lib/timevar.c (timervar_accumulate): Rename locals to
13498 avoid confusion with similarly-named more-global.
13499 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
13501 * src/output.c (prepare): Use xstrdup to convert char const *
13502 to char *, to avoid GCC warning.
13504 2002-10-19 Akim Demaille <akim@epita.fr>
13506 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
13507 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
13508 Use them to have `calc.y' ready for %pure-parser.
13509 * data/yacc.c (YYLEX): Pass a yylex return type to
13510 b4_c_function_call.
13512 2002-10-19 Akim Demaille <akim@epita.fr>
13514 Prototype support of %lex-param and %parse-param.
13516 * src/parse-gram.y: Add the definition of the %lex-param and
13517 %parse-param tokens, plus their rules.
13518 Drop the `_' version of %glr-parser.
13520 * src/scan-gram.l (INITIAL): Scan them.
13521 * src/muscle_tab.c: Comment changes.
13522 (muscle_insert, muscle_find): Rename `pair' as `probe'.
13523 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
13524 (muscle_entry_s): The `value' member is no longer const.
13525 Adjust all dependencies.
13526 * src/muscle_tab.c (muscle_init): Adjust: use
13527 MUSCLE_INSERT_STRING.
13528 Initialize the obstack earlier.
13529 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
13530 (muscle_pair_list_grow): New.
13531 * data/c.m4 (b4_c_function_call, b4_c_args): New.
13532 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
13533 * tests/calc.at: Use %locations, not --locations.
13534 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
13536 2002-10-19 Akim Demaille <akim@epita.fr>
13538 * src/getargs.c (usage): Take status as argument and exit
13540 Report the traditional `Try ... --help' message when status != 0.
13541 (usage, version): Don't take a FILE * as arg, it is pointless.
13542 (getargs): When there is an incorrect number of arguments, make it
13543 an error, and report it GNUlically thanks to `usage ()'.
13545 2002-10-18 Paul Eggert <eggert@twinsun.com>
13547 * data/glr.c (yyreportParseError): Don't assume that sprintf
13548 yields the length of the printed string, as this is not true
13549 on SunOS 4.1.4. Reported by Peter Klein.
13551 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
13552 * tests/conflicts.at (%nonassoc and eof): Likewise.
13553 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
13555 2002-10-17 Akim Demaille <akim@epita.fr>
13557 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
13558 * src/getargs.c (trace_types, trace_args): Adjust.
13559 * src/reader.c (grammar_current_rule_prec_set)
13560 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
13561 Standardize error messages.
13562 And s/@prec/%prec/!
13563 (reader): Use trace_flag to enable scanner/parser debugging,
13564 instead of an adhoc scheme.
13565 * src/scan-gram.l: Remove trailing debugging code.
13567 2002-10-16 Paul Eggert <eggert@twinsun.com>
13569 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
13572 * NEWS: Officially drop support for building Bison with K&R C,
13573 since it didn't work anyway and it's not worth worrying about.
13574 * Makefile.maint (wget_files): Remove ansi2knr.c.
13575 (ansi2knr.c-url_prefix): Remove.
13576 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
13577 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
13578 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
13580 2002-10-15 Paul Eggert <eggert@twinsun.com>
13582 Stop using the "enum_" trick for K&R-style function definitions;
13583 it confused me, and I was the author! Instead, assume that people
13584 who want to use K&R C compilers (when using these modules in GCC,
13585 perhaps?) will run ansi2knr.
13587 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
13588 All uses of "enum_" changed to "enum ".
13589 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

13600 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
13601 Use function prototypes; this removes the need for declaring
13602 static functions simply to provide their prototypes.

13677 tests/cxx-type.at, tests/headers.at, tests/input.at,
13678 tests/regression.at, tests/synclines.at, tests/torture.at:
13679 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
13680 so that the tests still work even if POSIXLY_CORRECT is set.
13681 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
13683 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
13684 for portability to K&R hosts. Fix typo: signed char is guaranteed
13685 only to 127, not to 128.
13686 * data/glr.c (yysigned_char): New type.
13687 * data/yacc.c (yysigned_char): Likewise.
13688 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
13690 2002-10-13 Paul Eggert <eggert@twinsun.com>
13692 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
13693 true due to limited range of data type" warning from GCC.
13695 * data/c.m4 (b4_token_defines): Protect against double-inclusion
13696 by wrapping enum yytokentype's definition inside #ifndef
13697 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
13699 2002-10-13 Akim Demaille <akim@epita.fr>
13701 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
13702 Un yy- yyrhs to avoid the name clash with the global YYRHS.
13704 2002-10-13 Akim Demaille <akim@epita.fr>
13706 * Makefile.maint: Update from Autoconf 2.54.
13707 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
13709 2002-10-13 Akim Demaille <akim@epita.fr>
13711 * src/print.c (print_state): Separate the list of solved conflicts
13712 from the other items.

13717 Let nondeterministic skeletons be usable with deterministic
13720 With the patch, GAWK compiled by GCC without -O2 passes its test
13721 suite using a GLR parser driven by LALR tables. It fails with -O2
13722 because `struct stat' gives two different answers on my machine:
13723 88 (definition of an auto var) and later 96 (memset on this var).
13724 Hence the stack is badly corrumpted. The headers inclusion is to
13725 blame: if I move the awk.h inclusion before GLR's system header
13726 inclusion, the two struct stat have the same size.
13728 * src/tables.c (pack_table): Always create conflict_table.
13729 (token_actions): Always create conflict_list.
13730 * data/glr.c (YYFLAG): Remove, unused.
13732 2002-10-13 Akim Demaille <akim@epita.fr>
13734 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
13736 (VALGRIND, GXX): New.
13737 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
13738 * tests/bison.in: Run $PREBISON a pre-command.

13745 * data/glr.c: Formatting changes.
13746 Tweak some trace messages to match yacc.c's.
13748 2002-10-13 Akim Demaille <akim@epita.fr>
13750 GLR parsers sometimes raise parse errors instead of performing the
13752 Reported by Charles-Henry de Boysson.
13754 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
13755 check the length of the traces when %glr.
13756 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
13758 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
13760 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
13761 (yyltype): Remove the yy prefix from the member names.
13762 (yytable): Complete its comment.
13763 (yygetLRActions): Map error action number from YYTABLE from
13765 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
13766 (which was a bug: it should have been YYTABEL_NINF, and yet it was
13767 not satisfying as we could compare an YYACTION computed from
13768 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
13769 only value for error actions.
13770 (yyreportParseError): In verbose parse error messages, don't issue
13771 `error' in the list of expected tokens.
13772 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
13773 next action to perform to match glr.c's decoding.
13774 (yytable): Complete its comment.

13778 Fix problem reported by Henrik Grubbstroem in
13779 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
13780 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
13781 because the Bison parser reads the second action before reducing
13783 * src/scan-gram.l (rule_length): New static var.
13784 Use it to keep track of the rule length in the scanner, since
13785 we can't expect the parser to be in lock-step sync with the scanner.
13786 (handle_action_dollar, handle_action_at): Use this var.
13787 * tests/actions.at (Exotic Dollars): Test for the problem.

13793 Include <sys/time.h> when checking for clock_t and struct tms.
13794 Use same include order as source.
13795 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
13796 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
13798 * lib/timevar.c: Update copyright date and clarify comments.
13799 (get_time) [IN_GCC]: Keep the GCC version for reference.
13801 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
13802 GCC version as of today, then merge Bison's changes.
13803 Change "GCC" to "Bison" in copyright notice. timevar.def's
13804 author is Akim, so change that too.
13806 * src/reader.c (grammar_current_rule_check):
13807 Don't worry about the default action if $$ is untyped.

13841 * lib/lbitset.c: Likewise.
13843 * lib/abitset.c (abitset_bytes): Return a size that is aligned
13844 properly for vectors of objects. Do not assume that adding a
13845 header size to a multiple of a word size yields a value that is
13846 properly aligned for the whole union.
13847 * lib/bitsetv.c (bitsetv_alloc): Likewise.
13849 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
13850 unique names for structures.

13882 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
13883 All instances of parameters of type enum bitset_opts are now of
13884 type enum_bitset_opts, to conform to the C Standard, and similarly
13885 for enum_bitset_type.

13887 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
13889 Do not use "struct bitset_struct" to mean different things in
13890 different modules. Not only is this confusing, it violates
13891 the C Standard, which requires that structure types in different
13892 modules must be compatible if one is to be passed to the other.
13893 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
13894 All instances of "struct bitset_struct *" replaced with "bitset".

13906 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
13909 Do not call a function of type T using a call that assumes the
13910 function is of a different type U. Standard C requires that a
13911 function must be called with a type that is compatible with its

13938 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
13939 the same width as int. This reapplies a hunk of the 2002-08-12 patch
13940 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
13941 which was inadvertently undone by the 2002-09-30 patch.

13951 * doc/bison.texinfo: Minor spelling, grammar, and white space
13953 (Symbols): Mention that any negative value returned from yylex
13954 signifies end-of-input. Warn about negative chars. Mention
13955 the portable Standard C character set.
13957 The GNU coding standard says CFLAGS and YFLAGS are reserved
13958 for the installer to set.

13967 * src/reader.c (reader): Use it.
13969 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
13970 POSIX 1003.1-2001 has removed fgrep.

14147 2002-09-06 Paul Eggert <eggert@twinsun.com>
14149 * doc/bison.texinfo (Conditions): Make explicit that the GPL
14150 exception applies only to yacc.c. This is a modification of a
14151 patch originally suggested by Akim Demaille.

14203 as int, and similarly for yyposn and YYINDEX.

14245 PROTOTYPES to check for prototypes, and "defined __STDC__" to

14251 (bitset_test): Now returns int, not unsigned long.

14300 as it mishandles negative chars and it may not work as expected
14301 outside the C locale.
14303 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
14304 this is a GCC extension and is not portable to other compilers.

14311 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
14314 * tests/regression.at: Do not use 'cc -c input.c -o input';
14315 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
14317 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
14318 exit status as failure, not just exit status 1. Sun C exits
14319 with status 2 sometimes.

14341 * tests/conflicts.at, tests/reduce.at: Adjust.

14482 Report rules which are never reduced by the parser: those hidden

14486 different: save its reduction (accept) instead of having a state
14487 without any action (no shift or goto, no reduce).
14488 Note: the final state is now a ``regular'' state, i.e., the
14489 parsers now contain `reduce 0' as default reduction.
14490 Nevertheless, since they decide to `accept' when yystate =
14491 final_state, they still will not reduce rule 0.

14537 yycontrol without making too strong assumptions on the parser
14539 * src/output.c (prepare_tokens): Use the real 0th value of
14540 token_translations instead of `0'.
14541 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
14543 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
14544 for the time being: %locations ought to provide it to yyerror.
14546 2002-07-25 Akim Demaille <akim@epita.fr>
14548 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
14549 * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./.
14550 * tests/regression.at (Web2c Actions): Adjust.
14552 2002-07-25 Akim Demaille <akim@epita.fr>
14554 Stop storing rules from 1 to nrules + 1.

16245 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
16246 full stderr, and strip it according to the bison options, instead

16250 Add an invocation exercising the error token.
16251 Add an invocation demonstrating a stupid error message.
16252 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

17014 2002-01-20 Marc Autret <marc@gnu.org>
17016 * tests/output.at: New test.
17017 * src/files.c (compute_base_names): Don't map extensions when
17018 the YACC flag is set, use defaults.
17019 Reported by Evgeny Stambulchik.
17021 2002-01-20 Marc Autret <marc@gnu.org>
17023 * src/system.h: Need to define __attribute__ away for non-GCC
17024 compilers as well (i.e., the vendor C compiler).
17025 Suggested by Albert Chin-A-Young.
17027 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
17029 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
17030 canonical definition.
17031 * src/system.h: Use the canonical definition for PARAMS (avoids
17032 a conflict with the macro from lib/hash.h).
17034 2002-01-11 Akim Demaille <akim@epita.fr>
17036 * configure.in: Use AC_FUNC_STRNLEN.
17037 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
17039 2002-01-09 Akim Demaille <akim@epita.fr>
17041 * src/files.c, src/files.h (output_infix): New.
17042 (tab_extension): Remove.
17043 (compute_base_names): Compute the former, drop the latter.
17044 * src/output.c (prepare): Insert the muscles `output-infix', and
17046 * src/parse-skel.y (string, string.1): New.
17047 (section.header): Use it.
17048 (section.yacc): Remove.
17049 (prefix): Remove too.
17050 * src/scan-skel.l: Adjust.
17051 * src/bison.simple, src/bison.hairy: Adjust.
17053 2002-01-09 Akim Demaille <akim@epita.fr>
17055 * configure.in (WERROR_CFLAGS): Compute it.
17056 * src/Makefile.am (CFLAGS): Pass it.
17057 * tests/atlocal.in (CFLAGS): Idem.
17058 * src/files.c: Fix a few warnings.
17059 (get_extension_index): Remove, unused.
17061 2002-01-08 Akim Demaille <akim@epita.fr>
17063 * src/getargs.c (AS_FILE_NAME): New.
17064 (getargs): Use it to convert DOSish file names.
17065 * src/files.c (base_name): Rename as full_base_name to avoid
17066 clashes with `base_name ()'.
17067 (filename_split): New.
17068 (compute_base_names): N-th rewrite, using filename_split.
17070 2002-01-08 Akim Demaille <akim@epita.fr>
17072 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
17073 New, stolen from the Fileutils 4.1.
17074 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
17075 * configure.in: Check for the presence of memrchr, and of its
17078 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
17080 * lib/hash.h (__P): Added definition for this macro.
17081 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
17082 BUILT_SOURCES, to ensure they are generated first.
17083 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
17084 %error-verbose to allow bootstrapping with bison 1.30x.
17086 2002-01-06 Akim Demaille <akim@epita.fr>
17088 * src/reader.c (parse_braces): Don't fetch the next char, the
17089 convention is to fetch on entry.
17090 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
17091 'switch' without a following semicolon.
17092 * tests/regression.at (braces parsing): New.
17094 2002-01-06 Akim Demaille <akim@epita.fr>
17096 Bison is dead wrong in its RR conflict reports.
17098 * tests/torture.at (GNU Cim Grammar): New.
17099 * src/conflicts.c (count_rr_conflicts): Fix.
17101 2002-01-06 Akim Demaille <akim@epita.fr>
17103 Creating package.m4 from configure.ac causes too many problems.
17105 * tests/Makefile.am (package.m4): Create it by hand,
17106 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
17108 2002-01-06 Akim Demaille <akim@epita.fr>
17110 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
17113 2002-01-04 Paul Eggert <eggert@twinsun.com>
17115 * doc/bison.texinfo (Debugging):
17116 Remove YYSTDERR; it's no longer defined or used.
17117 Also, s/cstdio.h/cstdio/.
17119 2002-01-03 Akim Demaille <akim@epita.fr>
17121 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
17123 2002-01-03 Akim Demaille <akim@epita.fr>
17125 * src/parse-skel.y (process_skeleton): Don't bind the parser's
17126 tracing code to --trace, wait for a better --trace option, with
17129 2002-01-03 Akim Demaille <akim@epita.fr>
17131 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
17132 The ISO C++ standard is extremely clear about it: stderr is
17133 considered a macro, not a regular symbol (see table 94 `Header
17134 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
17135 Therefore std:: does not apply to it. It still does with fprintf.
17136 Also, s/cstdio.h/cstdio/.
17138 2002-01-03 Akim Demaille <akim@epita.fr>
17140 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
17141 for non system headers.
17143 2002-01-02 Akim Demaille <akim@epita.fr>
17145 Equip the skeleton chain with location tracking, runtime trace,
17146 pure parser and scanner.
17148 * src/parse-skel.y: Request a pure parser, locations, and prefix
17150 (%union): Having several members with the same type does not help
17151 type mismatches, simplify.
17152 (YYPRINT, yyprint): New.
17153 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
17154 (skel_error): this.
17156 * src/scan-skel.l: Adjust to these changes.
17157 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
17158 (LOCATION_PRINT, skel_control_t): New.
17160 2001-12-30 Akim Demaille <akim@epita.fr>
17162 * src/parse-skel.y: Get rid of the shift/reduce conflict:
17163 replace `gb' with BLANKS.
17164 * src/scan-skel.l: Adjust.
17166 2001-12-30 Akim Demaille <akim@epita.fr>
17168 * src/system.h: We don't need nor want bcopy.
17169 Throw away MS-DOS crap: we don't need getpid.
17170 * configure.in: We don't need strndup. It was even causing
17171 problems: because Flex includes the headers *before* us,
17172 _GNU_SOURCE is not defined by config.h, and therefore strndup was
17174 * lib/xstrndup.c: New.
17175 * src/scan-skel.l: Use it.
17176 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
17177 * src/parse-skel.y: Use %directives instead of #defines.
17179 2001-12-30 Akim Demaille <akim@epita.fr>
17181 * src/skeleton.h: New.
17182 * src/output.c (output_parser, output_master_parser): Remove, dead
17184 * src/output.h (get_lines_number, actions_output, guards_output)
17185 (token_definitions_output): Prototype them.
17186 * src/parse-skel.y: Add the license notice.
17187 Include output.h and skeleton.h.
17188 (process_skeleton): Returns void, and takes a single parameter.
17189 * src/scan-skel.l: Add the license notice.
17190 Include skeleton.h.
17191 Don't use %option yylineno: it seems that then Flex imagines
17192 REJECT has been used, and therefore it won't reallocate its
17193 buffers (which makes no other sense to me than a bug). It results
17194 in warnings for `unused: yy_flex_realloc'.
17196 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
17198 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17199 (MUSCLE_INSERT_PREFIX): ...to there.
17200 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17201 (MUSCLE_INSERT_PREFIX): Move from here...
17203 * src/bison.hairy: Add a section directive. Put braces around muscle
17204 names. This parser skeleton is still broken, but Bison should not
17205 choke on a bad muscle 'syntax'.
17206 * src/bison.simple: Add a section directive. Put braces around muscle
17209 * src/files.h (strsuffix, stringappend): Add declarations.
17210 (tab_extension): Add declaration.
17211 (short_base_name): Add declaration.
17213 * src/files.c (strsuffix, stringappend): No longer static. These
17214 functions are used in the skeleton parser.
17215 (tab_extension): New.
17216 (compute_base_names): Use the computations done in this function
17217 to guess if the generated parsers should have '.tab' in their
17219 (short_base_name): No longer static.
17221 * src/output.c (output_skeleton): New.
17222 (output): Disable call to output_master_parser, and give a try to
17223 a new skeleton handling system.
17224 (guards_output, actions_output): No longer static.
17225 (token_definitions_output, get_lines_number): No longer static.
17227 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
17229 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
17232 * src/parse-skel.y: New file.
17233 * src/scan-skel.l: New file.
17235 2001-12-29 Akim Demaille <akim@epita.fr>
17237 %name-prefix is broken.
17239 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
17240 Adjust all dependencies.
17241 * tests/headers.at (export YYLTYPE): Strengthen this test: use
17244 Renaming yylval but not yylloc is not consistent. Now we do.
17246 * src/bison.simple: Prefix yylloc if used.
17247 * doc/bison.texinfo (Decl Summary): Document that.
17249 2001-12-29 Akim Demaille <akim@epita.fr>
17251 * doc/bison.texinfo: Promote `%long-directive' over
17253 Remove all references to fixed-output-files, yacc is enough.
17255 2001-12-29 Akim Demaille <akim@epita.fr>
17257 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
17258 user prologue. These are defaults.
17259 * tests/actions.at (Mid-rule actions): Make sure the user can
17260 define YYDEBUG and YYERROR_VERBOSE.
17262 2001-12-29 Akim Demaille <akim@epita.fr>
17264 * src/output.c (header_output): Don't forget to export YYLTYPE and
17266 * tests/headers.at (export YYLTYPE): New, make sure it does.
17267 * tests/regression.at (%union and --defines, Invalid CPP headers):
17269 * tests/headers.at: here.
17271 2001-12-29 Akim Demaille <akim@epita.fr>
17273 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
17275 2001-12-29 Akim Demaille <akim@epita.fr>
17277 * tests/actions.at (Mid-rule actions): Output on a single line
17278 instead of several.
17280 2001-12-29 Akim Demaille <akim@epita.fr>
17282 * doc/bison.texinfo: Formatting changes.
17284 2001-12-29 Akim Demaille <akim@epita.fr>
17286 Don't store the token defs in a muscle, just be ready to output it
17287 on command. Now possible via `symbols'. Fixes a memory leak.
17289 * src/output.c (token_definitions_output): New.
17290 (output_parser, header_output): Use it.
17291 * src/reader.c (symbols_save): Remove.
17293 2001-12-29 Akim Demaille <akim@epita.fr>
17295 * src/bison.simple: Do not provide a default for YYSTYPE and
17296 YYLTYPE before the user's prologue. Otherwise it's hardly... a
17299 2001-12-29 Akim Demaille <akim@epita.fr>
17301 Mid-rule actions are simply... ignored!
17303 * src/reader.c (readgram): Be sure to attach mid-rule actions to
17304 the empty-rule associated to the dummy symbol, not to the host
17306 * tests/actions.at (Mid-rule actions): New.
17308 2001-12-29 Akim Demaille <akim@epita.fr>
17312 * src/reader.c (reader): Free grammar.
17314 2001-12-29 Akim Demaille <akim@epita.fr>
17318 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
17319 since it allocates it for each state, although only one is needed.
17320 (allocate_storage): Do it here.
17322 2001-12-29 Akim Demaille <akim@epita.fr>
17324 * src/options.h, src/options.c (create_long_option_table): Rename
17326 (long_option_table_new): this, with a clearer prototype.
17327 (percent_table): Remove, unused,
17328 * src/getargs.c (getargs): Adjust.
17330 2001-12-29 Akim Demaille <akim@epita.fr>
17332 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
17333 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
17336 2001-12-29 Akim Demaille <akim@epita.fr>
17338 * src/lalr.c (build_relations): Rename `states' as `states1'.
17339 Sorry, I don't understand exactly what it is, no better name...
17341 2001-12-29 Akim Demaille <akim@epita.fr>
17343 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
17344 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
17345 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
17348 2001-12-29 Akim Demaille <akim@epita.fr>
17350 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
17353 2001-12-29 Akim Demaille <akim@epita.fr>
17355 * src/reader.c, src/reader.h (user_toknums): Remove.
17356 Adjust all users to use symbols[i]->user_token_number.
17358 2001-12-29 Akim Demaille <akim@epita.fr>
17360 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
17361 Adjust all users to use symbols[i]->prec or ->assoc.
17363 2001-12-29 Akim Demaille <akim@epita.fr>
17365 * src/reader.c, src/reader.h (tags): Remove.
17366 Adjust all users to use symbols[i]->tag.
17368 2001-12-29 Akim Demaille <akim@epita.fr>
17370 * src/gram.h, src/gram.c (symbols): New, similar to state_table
17372 * src/reader.c (packsymbols): Fill this table.
17374 * src/conflicts.c (resolve_sr_conflict): Adjust.
17375 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
17377 Use symbols[i]->tag instead of tags[i].
17379 2001-12-29 Akim Demaille <akim@epita.fr>
17381 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
17382 In addition, put a comment in there, to replace...
17383 * tests/regression.at (%union and C comments): Remove.
17385 2001-12-29 Akim Demaille <akim@epita.fr>
17387 * tests/regression.at (Web2c Actions): Blindly move the actual
17388 output as expected output. The contents *seem* right to me, but I
17389 can't pretend reading perfectly parser tables... Nonetheless, all
17390 the other tests pass correctly, the table look OK, even though the
17391 presence of `$axiom' is to be noted: AFAICS it is useless (but
17394 2001-12-29 Akim Demaille <akim@epita.fr>
17396 * src/reader.c (readgram): Don't add the rule 0 if there were no
17397 rules read. In other words, add it _after_ having performed
17398 grammar sanity checks.
17399 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
17401 2001-12-29 Akim Demaille <akim@epita.fr>
17403 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
17404 visible, and some states have now a different number.
17406 2001-12-29 Akim Demaille <akim@epita.fr>
17408 * src/reader.c (readgram): Bind the initial rule's lineno to that
17410 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
17411 (Solved SR Conflicts): Adjust rule 0's line number.
17413 2001-12-29 Akim Demaille <akim@epita.fr>
17415 Fix the `GAWK Grammar' failure.
17417 * src/LR0.c (final_state): Initialize to -1 so that we do compute
17418 the reductions of the first state which was mistakenly confused
17419 with the final state because precisely final_state was initialized
17421 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
17422 now noticed by Bison.
17423 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
17424 have a reduction on $default.
17426 2001-12-29 Akim Demaille <akim@epita.fr>
17428 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
17430 * src/closure.c (print_closure): Likewise.
17431 * src/derives.c (print_derives): Likewise.
17432 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
17435 2001-12-29 Akim Demaille <akim@epita.fr>
17437 * src/lalr.c (lookaheads_print): New.
17438 (lalr): Call it when --trace-flag.
17439 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
17442 2001-12-29 Akim Demaille <akim@epita.fr>
17444 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
17445 when walking through ritem, even via rule->rhs.
17446 * src/reduce.c (dump_grammar, useful_production, reduce_output)
17447 (useful_production, useless_nonterminals): Likewise.
17448 (reduce_grammar_tables): Likewise, plus update nritems.
17449 * src/nullable.c (set_nullable): Likewise.
17450 * src/lalr.c (build_relations): Likewise.
17451 * tests/sets.at (Nullable): Adjust.
17452 Fortunately, now, the $axiom is no longer nullable.
17454 2001-12-29 Akim Demaille <akim@epita.fr>
17456 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
17458 * src/gram.c (ritem_longest_rhs): Likewise.
17459 * src/reduce.c (nonterminals_reduce): Likewise.
17460 * src/print_graph.c (print_graph): Likewise.
17461 * src/output.c (output_rule_data): Likewise.
17462 * src/nullable.c (set_nullable): Likewise.
17464 2001-12-29 Akim Demaille <akim@epita.fr>
17466 * src/output.c: Comment changes.
17468 2001-12-27 Paul Eggert <eggert@twinsun.com>
17470 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
17471 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
17472 Sparc, as they were causing more porting problems than the
17473 (minor) performance improvement was worth.
17475 Also, catch up with 1.31's YYSTD.
17477 2001-12-27 Akim Demaille <akim@epita.fr>
17479 * src/output.c (output_gram): Rely on nritems, not the
17480 0-sentinel. See below.
17481 Use -1 as separator, not 0.
17482 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
17483 Rely on -1 as separator in yyrhs, instead of 0.
17484 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
17485 twice `Now at end of input', therefore there are two lines less to
17488 2001-12-27 Akim Demaille <akim@epita.fr>
17490 * tests/regression.at (Unresolved SR Conflicts):
17491 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
17494 2001-12-27 Akim Demaille <akim@epita.fr>
17496 * src/LR0.c (new_state): Recognize the final state by the fact it
17497 is reached by eoftoken.
17498 (insert_start_shifting_state, insert_eof_shifting_state)
17499 (insert_accepting_state, augment_automaton): Remove, since now
17500 these states are automatically computed from the initial state.
17501 (generate_states): Adjust.
17502 * src/print.c: When reporting a rule number to the user, substract
17503 1, so that the axiom rule is rule 0, and the first user rule is 1.
17504 * src/reduce.c: Likewise.
17505 * src/print_graph.c (print_core): For the time being, just as for
17506 the report, depend upon --trace-flags to dump the full set of
17508 * src/reader.c (readgram): Once the grammar read, insert the rule
17509 0: `$axiom: START-SYMBOL $'.
17510 * tests/set.at: Adjust: rule 0 is now displayed, and since the
17511 number of the states has changed (the final state is no longer
17512 necessarily the last), catch up.
17514 2001-12-27 Akim Demaille <akim@epita.fr>
17516 Try to make the use of the eoftoken valid. Given that its value
17517 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
17518 is used instead of > 0 where appropriate, (ii), depend upon nritems
17519 instead of the 0-sentinel.
17521 * src/gram.h, src/gram.c (nritems): New.
17522 Expected to be duplication of nitems, but for the time being...
17523 * src/reader.c (packgram): Assert nritems and nitems are equal.
17524 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
17525 * src/closure.c (print_closure, print_fderives): Likewise.

17530 2001-12-27 Akim Demaille <akim@epita.fr>
17532 * src/main.c (main): If there are complains after grammar
17533 reductions, then output the report anyway if requested, then die.
17534 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
17535 * src/reader.c (eoftoken): New.
17536 (parse_token_decl): If the token being defined has value `0', it
17538 (packsymbols): No longer hack `tags' to insert `$' by hand.
17539 Be sure to preserve the value of the eoftoken.
17540 (reader): Make sure eoftoken is defined.
17541 Initialize nsyms to 0: now eoftoken is created just like the others.
17542 * src/print.c (print_grammar): Don't special case the eof token.
17543 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
17544 lie anyway, albeit pleasant.
17545 * tests/calc.at: Exercise error messages with eoftoken.
17546 Change the grammar so that empty input is invalid.
17547 Adjust expectations.
17548 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
17550 2001-12-27 Akim Demaille <akim@epita.fr>
17552 * configure.in: Check the protos of strchr ans strspn.
17553 Replace strchr if needed.
17554 * src/system.h: Provide the protos of strchr, strspn and memchr if
17556 * lib/strchr.c: New.
17557 * src/reader.c (symbols_save): Use strchr.
17559 2001-12-27 Akim Demaille <akim@epita.fr>
17561 * src/print.c, src/print_graph.c (escape): New.
17562 Use it to quote the TAGS outputs.
17563 * src/print_graph.c (print_state): Now errors are in red, and
17564 reductions in green.
17565 Prefer high to wide: output the state number on a line of its own.
17567 2001-12-27 Akim Demaille <akim@epita.fr>
17569 * src/state.h, src/state.c (reductions_new): New.
17570 * src/LR0.c (set_state_table): Let all the states have a
17571 `reductions', even if reduced to 0.

17590 2001-12-27 Akim Demaille <akim@epita.fr>
17592 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
17593 * src/print.c: here.
17594 (lookaheadset, shiftset): New, used as additional storage by
17596 (print_results): Adjust.
17597 (print_shifts, print_gotos, print_errs): New, extracted from...
17598 (print_actions): here.
17599 * src/print_graph.c (print_actions): Remove dead code.
17601 2001-12-27 Akim Demaille <akim@epita.fr>

17606 2001-12-27 Akim Demaille <akim@epita.fr>
17608 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
17609 (build_relations): Adjust.
17611 2001-12-27 Akim Demaille <akim@epita.fr>
17613 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
17616 2001-12-27 Akim Demaille <akim@epita.fr>
17618 * src/reader.c (packgram): Catch nitems overflows.
17620 2001-12-27 Akim Demaille <akim@epita.fr>
17622 * src/files.c, src/files.h (guard_obstack): Remove.
17623 * src/output.c (output): Adjust.
17624 * src/reader.c (parse_braces): New, factoring...
17625 (copy_action, copy_guard): these two which are renamed as...
17626 (parse_action, parse_guard): these.
17627 As a voluntary consequence, using braces around guards is now
17630 2001-12-27 Akim Demaille <akim@epita.fr>
17632 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
17633 * src/reader.c (symbol_list): `guard' and `guard_line' are new
17635 (symbol_list_new): Adjust.
17636 (copy_action): action_line is the first line, not the last.
17637 (copy_guard): Just as for actions, store the `action' only, not
17638 the switch/case/break flesh.
17639 Don't parse the user action that might follow the guard, let...
17640 (readgram): do it, i.e., now, there can be an action after a
17642 In other words the guard is just explicitly optional.
17643 (packgram): Adjust.
17644 * src/output.c (guards_output): New.
17645 (output_parser): Call it when needed.
17646 (output): Also free the guard and attrs obstacks.
17647 * src/files.c, src/files.h (obstack_save): Remove.
17648 (output_files): Remove.
17649 As a result, if one needs the former `.act' file, using an
17650 appropriate skeleton which requires actions and guards is now
17652 * src/main.c (main): Adjust.
17653 * tests/semantic.at: New.
17654 * tests/regression.at: Use `input.y' as input file name.
17655 Avoid 8+3 problems by requiring input.c when the test needs the

17660 * src/reader.c (symbol_list_new): Be sure to initialize all the
17663 2001-12-27 Akim Demaille <akim@epita.fr>
17665 All the hacks using a final pseudo state are now useless.
17667 * src/LR0.c (set_state_table): state_table holds exactly nstates.
17668 * src/lalr.c (nLA): New.
17669 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
17670 instead of lookaheadsp from the pseudo state (nstate + 1).
17672 2001-12-27 Akim Demaille <akim@epita.fr>
17674 * src/output.c (action_row, token_actions): Use a state_t instead
17675 of a integer, and nlookaheads instead of the following state's

17682 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
17683 (conflicts_print, print_reductions): Use a state_t instead of an
17684 integer when referring to a state.
17685 As much as possible, depend upon nlookaheads, instead of the
17686 `lookaheadsp' member of the following state (since lookaheads of
17687 successive states are successive, the difference between state n + 1
17688 and n served as the number of lookaheads for state n).
17689 * src/lalr.c (add_lookback_edge): Likewise.
17690 * src/print.c (print_core, print_actions, print_state)
17691 (print_results): Likewise.
17692 * src/print_graph.c (print_core, print_actions, print_state)

17701 Add plenty of `static'.
17703 2001-12-27 Akim Demaille <akim@epita.fr>
17705 * src/output.c (prepare): Drop the muscle `ntbase' which
17706 duplicates ntokens.
17707 * src/bison.simple: Formatting/comment changes.
17708 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
17709 is an undocumented synonym.
17711 2001-12-22 Akim Demaille <akim@epita.fr>
17713 * src/output.c (output_table_data): Change the prototype to use
17714 `int' for array ranges: some invocations do pass an int, not a
17716 Reported by Wayne Green.
17718 2001-12-22 Akim Demaille <akim@epita.fr>
17720 Some actions of web2c.y are improperly triggered.
17721 Reported by Mike Castle.
17723 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
17724 * tests/regression.at (Web2c): Rename as...
17725 (Web2c Report): this.
17726 (Web2c Actions): New.
17728 2001-12-22 Akim Demaille <akim@epita.fr>

17734 * tests/regression.at (Web2c): New.
17736 2001-12-18 Akim Demaille <akim@epita.fr>
17738 Some host fail on `assert (!"foo")', which expands to
17739 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
17740 Reported by Nelson Beebee.
17742 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
17743 `#define it_succeeded 0' and `assert (it_succeeded)'.
17745 2001-12-17 Marc Autret <autret_m@epita.fr>
17747 * src/bison.simple: Don't hard code the skeleton line and filename.
17748 * src/output.c (output_parser): Rename 'line' as 'output_line'.
17749 New line counter 'skeleton_line' (skeleton-line muscle).
17751 2001-12-17 Paul Eggert <eggert@twinsun.com>
17753 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
17754 YYDEBUG must be defined to a nonzero value.
17756 * src/bison.simple (yytname): Do not assume that the user defines
17757 YYDEBUG to a properly parenthesized expression.
17759 2001-12-17 Akim Demaille <akim@epita.fr>
17761 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
17762 nlookaheads is a new member.
17764 * src/lalr.h (nlookaheads): Remove this orphan declaration.
17765 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
17768 2001-12-17 Akim Demaille <akim@epita.fr>
17770 * src/files.h, src/files.c (open_files, close_files): Remove.
17771 * src/main.c (main): Don't open/close files, nor invoke lex_free,
17773 * src/reader.c (reader): Do it.
17775 2001-12-17 Akim Demaille <akim@epita.fr>
17777 * src/conflicts.c (print_reductions): Formatting changes.
17779 2001-12-17 Akim Demaille <akim@epita.fr>
17781 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
17782 (flush_reduce): New.
17783 (resolve_sr_conflict): Adjust.
17785 2001-12-17 Akim Demaille <akim@epita.fr>
17787 * src/output.c (output_obstack): Be static and rename as...
17788 (format_obstack): this, to avoid any confusion with files.c's
17790 * src/reader.h (muscle_obstack): Move to...
17791 * src/output.h: here, since it's defined in output.c.
17793 2001-12-17 Akim Demaille <akim@epita.fr>
17795 * src/output.c (action_row, save_column, default_goto)
17796 (sort_actions, matching_state, pack_vector): Better variable
17799 2001-12-17 Akim Demaille <akim@epita.fr>
17801 * src/output.c: Various formatting changes.
17803 2001-12-17 Akim Demaille <akim@epita.fr>
17805 * src/files.c (output_files): Free the output_obstack.
17806 * src/main.c (main): Call print and print_graph conditionally.
17807 * src/print.c (print): Work unconditionally.
17808 * src/print_graph.c (print_graph): Work unconditionally.
17809 * src/conflicts.c (log_resolution): Output only if verbose_flag.
17811 2001-12-16 Marc Autret <autret_m@epita.fr>
17813 * src/output.c (actions_output): Fix. When we use %no-lines,
17814 there is one less line per action.
17816 2001-12-16 Marc Autret <autret_m@epita.fr>
17818 * src/bison.simple: Remove a useless #line directive.
17819 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
17820 * src/output.c (get_lines_number): New.
17821 (output_parser): Adjust, now takes care about the lines of a
17823 Fix line numbering.
17824 (actions_output): Computes the number of lines taken by actions.
17825 (output_master_parser): Insert new skeleton which is the name of
17826 the output parser file name.
17828 2001-12-15 Marc Autret <autret_m@epita.fr>
17830 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
17832 2001-12-15 Marc Autret <autret_m@epita.fr>
17834 * src/output.c (output_gram): Keep track of the hairy one.
17836 2001-12-15 Akim Demaille <akim@epita.fr>
17838 Make `make distcheck' work.
17840 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
17841 system.h which uses libgettext.h.
17843 2001-12-15 Akim Demaille <akim@epita.fr>
17845 * src/nullable.c (set_nullable): Useless rules must be skipped,
17846 otherwise, since we range over their symbols, we might look at a
17847 nonterminal which no longer ``exists'', i.e., it is not counted in
17848 `nvars', hence we overflow our arrays.
17850 2001-12-15 Akim Demaille <akim@epita.fr>
17852 The header can also be produced directly, without any obstack!
17855 * src/files.c, src/files.h (defines_obstack): Remove.
17856 (compute_header_macro): Global.
17857 (defines_obstack_save): Remove.
17858 * src/reader.c (parse_union_decl): No longer output to
17859 defines_obstack: its content can be found in the `stype' muscle
17861 (output_token_translations): Merge into...
17862 (symbols_output): this.
17864 (symbols_save): this.
17866 * src/output.c (header_output): New.
17869 2001-12-15 Akim Demaille <akim@epita.fr>
17871 * src/reader.c (parse_union_decl): Instead of handling two obstack
17872 simultaneously, use one to define the `stype' muscle, and use the
17873 value of the latter to fill defines_obstack.
17874 (copy_comment): Remove.
17875 (copy_comment2): Work for a single obstack.
17877 (copy_comment): this.
17879 2001-12-15 Akim Demaille <akim@epita.fr>
17881 * src/lex.c, src/lex.h (xgetc): No longer static.
17882 * src/reader.c (parse_union_decl): Revamp.
17884 2001-12-15 Akim Demaille <akim@epita.fr>
17886 Still making progress in separating Bison into (i) input, (ii)
17887 process, (iii) output: now we can directly output the parser file
17888 without using table_obstack at all.
17890 * src/files.c, src/files.h (table_obstack): Bye bye.
17891 (parser_file_name): New.
17892 * src/files.c (compute_output_file_names): Compute it.
17893 * src/output.c (actions_output, output_parser)
17894 (output_master_parser): To a file instead of an obstack.
17896 2001-12-15 Akim Demaille <akim@epita.fr>
17898 Attach actions to rules, instead of pre-outputting them to
17901 * src/gram.h (rule_t): action and action_line are new members.
17902 * src/reader.c (symbol_list): Likewise.
17903 (copy_action): Save the actions within the rule.
17904 (packgram): Save them in rule_table.
17905 * src/output.c (actions_output): New.
17906 (output_parser): Use it on `%%actions'.
17907 (output_rule_data): Don't free rule_table.
17909 (prepare): Don't save the `action' muscle.
17910 * src/bison.simple: s/%%action/%%actions/.
17912 2001-12-15 Akim Demaille <akim@epita.fr>
17914 * src/reader.c (copy_action): When --yacc, don't append a `;'
17915 to the user action: let it fail if lacking.
17916 Suggested by Arnold Robbins and Tom Tromey.
17918 2001-12-14 Akim Demaille <akim@epita.fr>
17920 * src/lex.c (literalchar): Simply return the char you decoded, non
17921 longer mess around with obstacks and int pointers.
17922 Adjust all callers.
17924 2001-12-14 Akim Demaille <akim@epita.fr>
17926 * src/lex.c (literalchar): Don't escape the special characters,
17927 just decode them, and keep them as char (before, eol was output as
17928 the 2 char string `\n' etc.).
17929 * src/output.c (output_rule_data): Use quotearg to output the
17932 2001-12-13 Paul Eggert <eggert@twinsun.com>
17934 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
17935 Do not infringe on the global user namespace when using C++.
17936 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
17937 All uses of `fprintf' and `stderr' changed.
17939 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
17941 2001-12-13 Akim Demaille <akim@epita.fr>
17943 The computation of nullable is broken: it doesn't handle empty
17946 * tests/torture.at (GNU AWK Grammar): New.
17947 * tests/sets.at (Nullable): New.
17948 * src/nullable.c (set_nullable): Instead of blindly looping over
17949 `ritems', loop over the rules, and then over their rhs's.
17951 Work around Autotest bugs.
17953 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
17954 frame, because Autotest understand lines starting with a `+' as
17955 traces from the shell. Then, they are not processed properly.
17956 Admittedly an Autotest bug, but we don't have time to wait for
17957 Autotest to catch up.
17958 * tests/regression.at (Broken Closure): Adjust to the new table
17961 * tests/sets.at: here.
17963 2001-12-13 Akim Demaille <akim@epita.fr>
17965 * src/closure.c (closure): Use nrules instead of playing tricks
17966 with BITS_PER_WORD.
17968 2001-12-13 Akim Demaille <akim@epita.fr>
17970 * src/print.c (print_actions): Output the handling of `$' as the
17971 traces do: shifting the token EOF. Before EOF was treated as a
17973 * tests/regression.at: Adjust some tests.
17974 * src/print_graph.c (print_core): Complete the set of items via
17975 closure. The next-to-final and final states are still unsatisfying,
17976 but that's to be addressed elsewhere.
17977 No longer output the rule numbers, but do output the state number.
17978 A single loop for the shifts + gotos is enough, but picked a
17979 distinct color for each.
17980 (print_graph): Initialize and finalize closure.
17982 2001-12-13 Akim Demaille <akim@epita.fr>
17984 * src/reader.c (readgram): Remove dead code, an strip useless
17986 (get_type): Remove, unused.
17988 2001-12-12 Akim Demaille <akim@epita.fr>
17990 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
17991 on that of lib/error.c.
17993 2001-12-12 Akim Demaille <akim@epita.fr>
17995 Some hosts don't like `/' in includes.
17997 * src/system.h: Include libgettext.h without qualifying the path.
17998 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
18001 2001-12-11 Marc Autret <autret_m@epita.fr>
18003 * src/output.c (output_parser): Remove useless muscle.
18005 2001-12-11 Marc Autret <autret_m@epita.fr>
18007 * src/bison.simple: Remove #line just before %%epilogue. It
18008 is now handled in ...
18009 * src/reader.c (read_additionnal_code): Add the output of a
18010 #line for the epilogue.
18012 2001-12-10 Marc Autret <autret_m@epita.fr>
18014 * src/reader.c (copy_definition): Re-use CPP-outed code which
18015 replace precedent remove.
18016 * src/bison.simple: Remove #line before %%prologue because
18017 %%input-line is wrong at this time.
18019 2001-12-10 Marc Autret <autret_m@epita.fr>
18021 * src/reader.c (symbols_output): Clean up.
18022 * src/output.c (output_gram, output): Clean up.
18024 2001-12-10 Akim Demaille <akim@epita.fr>
18026 * src/lalr.c (initialize_lookaheads): New. Extracted from...
18027 * src/LR0.c (set_state_table): here.
18028 * src/lalr.c (lalr): Call it.
18030 2001-12-10 Akim Demaille <akim@epita.fr>
18032 * src/state.h (shifts): Remove the `number' member: shifts are
18033 attached to state, hence no longer need to be labelled with a
18036 2001-12-10 Akim Demaille <akim@epita.fr>
18038 Now that states have a complete set of members, the linked list of
18039 shifts is useless: just fill directly the state's shifts member.
18041 * src/state.h (shifts): Remove the `next' member.
18042 * src/LR0.c (first_state, last_state): Remove.
18043 Adjust the callers.
18044 (augment_automaton): Don't look for the shifts that must be added
18045 a shift on EOF: it is those of the state we looked for! But now,
18046 since shifts are attached, it is no longer needed to looking
18047 merely by its id: its number.
18049 2001-12-10 Akim Demaille <akim@epita.fr>
18051 * src/LR0.c (augment_automaton): Better variable locality.
18052 Remove an impossible branch: if there is a state corresponding to
18053 the start symbol being shifted, then there is shift for the start
18054 symbol from the initial state.
18056 2001-12-10 Akim Demaille <akim@epita.fr>
18058 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
18059 only when appropriate: when insert_start_shifting_state' is not
18061 * tests/regression.at (Rule Line Numbers): Adjust.
18063 2001-12-10 Akim Demaille <akim@epita.fr>
18065 * src/LR0.c (augment_automaton): Now that all states have shifts,
18066 merge the two cases addition shifts to the initial state.
18068 2001-12-10 Akim Demaille <akim@epita.fr>
18070 * src/lalr.c (set_state_table): Move to...
18072 * src/lalr.c (lalr): Don't call it...
18073 * src/LR0.c (generate_states): do it.
18074 * src/LR0.h (first_state): Remove, only the table is used.
18076 2001-12-10 Akim Demaille <akim@epita.fr>
18078 * src/LR0.h (first_shift, first_reduction): Remove.
18079 * src/lalr.c: Don't use first_shift: find shifts through the
18082 2001-12-10 Akim Demaille <akim@epita.fr>
18084 * src/LR0.c: Attach shifts to states as soon as they are
18086 * src/lalr.c (set_state_table): Instead of assigning shifts to
18087 state, just assert that the mapping was properly done.
18089 2001-12-10 Akim Demaille <akim@epita.fr>
18091 * src/LR0.c (insert_start_shift): Rename as...
18092 (insert_start_shifting_state): this.
18093 (insert_eof_shifting_state, insert_accepting_state): New.
18094 (augment_automaton): Adjust.
18095 Better locality of the variables.
18096 When looking if the start_symbol is shifted from the initial
18097 state, using `while (... symbol != start_symbol ...)' sounds
18098 better than `while (... symbol < start_symbol ...)': If fail
18099 to see how the order between symbols could be relevant!
18101 2001-12-10 Akim Demaille <akim@epita.fr>
18103 * src/getargs.h: Don't declare `spec_name_prefix' and
18104 `spec_file_prefix', declared by src/files.h.
18105 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
18106 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
18107 * src/output.c (prepare): Adjust.
18108 * src/reader.c (symbols_output): Likewise.
18109 * src/vmsgetargs.c: Vaguely adjust, but who cares?
18111 2001-12-10 Akim Demaille <akim@epita.fr>
18113 * src/muscle_tab.c (muscle_init): NULL is a better default than
18116 2001-12-10 Akim Demaille <akim@epita.fr>
18118 * src/reader.c (reader): Calling symbols_output once is enough.
18120 2001-12-10 Akim Demaille <akim@epita.fr>
18122 Now that states have a complete set of members, the linked list of
18123 reductions is useless: just fill directly the state's reductions
18126 * src/state.h (struct reductions): Remove member `number' and
18128 * src/LR0.c (first_reduction, last_reduction): Remove.
18129 (save_reductions): Don't link the new reductions, store them in
18131 * src/lalr.c (set_state_table): No need to attach reductions to
18132 states, it's already done.
18133 * src/output.c (output_actions): No longer free the shifts, then
18134 the reductions, then the states: free all the states and their
18137 2001-12-10 Akim Demaille <akim@epita.fr>
18139 * src/options.c (OPTN, DRTV, BOTH): New.
18140 (option_table): Use them.
18142 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
18143 the job of system.h.
18144 * src/options.c: Don't include stdio.h and xalloc.h for the same
18147 2001-12-10 Akim Demaille <akim@epita.fr>
18149 * src/output.c (output, prepare): Make sure the values of the
18150 muscles `action' and `prologue' are 0-terminated.
18152 2001-12-10 Akim Demaille <akim@epita.fr>
18154 Clean up GCC warnings.
18156 * src/reader.c (copy_action): `buf' is not used.
18157 (parse_skel_decl): Be static.
18158 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
18159 * src/options.h (create_long_option_table): Have a real prototype.
18160 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
18161 (hash_delete_at): Return const void *.
18162 Adjust casts to preserve the const.
18164 2001-12-10 Akim Demaille <akim@epita.fr>
18166 * configure.in: Require 2.52g.
18167 M4 is not needed, but AUTOM4TE is.
18168 * m4/m4.m4: Remove.
18169 * tests/Makefile.am: Adjust.
18171 2001-12-10 Akim Demaille <akim@epita.fr>
18173 One structure for states is enough, even though theoretically
18174 there are LR(0) states and LALR(1) states.
18176 * src/lalr.h (state_t): Remove.
18177 (state_table): Be state_t **, not state_t *.
18178 * src/state.h (core, CORE_ALLOC): Rename as...
18179 (state_t, STATE_ALLOC): this.
18180 Add the LALR(1) members: shifts, reductions, errs.
18181 * src/LR0.c (state_table): Rename as...
18182 (state_hash): this, to avoid name clashes with the global
18184 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
18185 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
18187 2001-12-10 Akim Demaille <akim@epita.fr>
18189 Bison dumps core on bash.y.
18190 Reported by Pascal Bart.
18192 * src/warshall.c (bitmatrix_print): New.
18194 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
18195 j must be the outer loop.
18196 * tests/regression.at (Broken Closure): New.
18198 2001-12-05 Akim Demaille <akim@epita.fr>
18200 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
18202 Reported by Peter Hamorsky.
18204 2001-12-05 Akim Demaille <akim@epita.fr>
18206 * src/conflicts.c (err_table): Remove.
18207 (resolve_sr_conflict): Adjust.
18208 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
18210 (state_t.reductions, state_t.shifts): this.
18212 2001-12-05 Akim Demaille <akim@epita.fr>
18214 * src/reduce.c (reduce_grammar_tables): No longer disable the
18215 removal of useless rules via CPP but via `if (0)', so that the
18216 compiler still check the code is valid.
18217 For instance, it should have noticed `rline' no longer exists: use
18218 the `line' member of rule_t.
18219 * src/gram.c (dummy, rline): Remove, unused.
18221 2001-12-05 Akim Demaille <akim@epita.fr>
18223 * src/output.c (pack_vector): Use assert, not berror.
18224 * src/main.c (berror): Remove, unused.
18226 2001-12-05 Akim Demaille <akim@epita.fr>
18228 New experimental feature: if --verbose --trace output all the
18229 items of a state, not only its kernel.
18231 * src/print.c (print_core): If `trace_flag', then invoke closure
18232 before outputting the items of the state (print_core is no longer
18233 a correct name them).
18234 (print_results): Invoke new_closure/free_closure if needed.
18236 2001-12-05 Akim Demaille <akim@epita.fr>
18238 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
18239 * src/closure.c, src/closure.h (itemsetsize): Rename as...
18240 (nitemset): for consistency with the rest of the project.
18242 2001-12-05 Akim Demaille <akim@epita.fr>
18244 * src/closure.c (print_closure): Improve.
18245 (closure): Use it for printing input and output.
18247 2001-12-05 Akim Demaille <akim@epita.fr>
18249 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
18250 indexed by nonterminals.
18252 2001-12-05 Akim Demaille <akim@epita.fr>
18254 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
18256 * src/warshall.h: Remove accidental duplication of the content.
18258 2001-12-05 Akim Demaille <akim@epita.fr>

18270 2001-12-05 Akim Demaille <akim@epita.fr>
18272 * src/output.c (action_row): De-obfuscate
18273 using the good o' techniques: arrays not pointers, variable
18274 locality, BITISSET, RESETBIT etc.
18276 2001-12-05 Akim Demaille <akim@epita.fr>
18278 Pessimize the code to simplify it: from now on, all the states
18279 have a valid SHIFTS, which NSHIFTS is possibly 0.
18281 * src/LR0.c (shifts_new): Be global and move to..
18282 * src/state.c, src/state.h: here.
18283 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
18284 * src/print_graph: Adjust.
18286 2001-12-05 Akim Demaille <akim@epita.fr>
18288 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
18289 * src/conflicts.c: Use it.
18290 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
18291 incorrectly ``simplified''.
18293 2001-12-05 Akim Demaille <akim@epita.fr>
18295 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
18296 using the good o' techniques: arrays not pointers, variable
18297 locality, BITISSET, RESETBIT etc.
18299 2001-12-05 Akim Demaille <akim@epita.fr>
18301 * src/state.h (SHIFT_SYMBOL): New.
18302 * src/conflicts.c: Use it to deobfuscate.

18306 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
18307 (print_reductions): De-obfuscate using the good o' techniques:
18308 arrays not pointers, variable locality, BITISSET.
18310 2001-12-05 Akim Demaille <akim@epita.fr>
18312 * src/conflicts.c (print_reductions): Arrays, not pointers.

18331 2001-12-05 Akim Demaille <akim@epita.fr>
18333 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
18334 * src/lalr.c: Use them.
18336 2001-12-05 Akim Demaille <akim@epita.fr>
18338 * src/LR0.c (augment_automaton): Formatting changes.
18339 Better variable locality.
18341 2001-12-05 Akim Demaille <akim@epita.fr>
18343 * src/lalr.c (matrix_print): New.
18344 (transpose): Use it.
18345 Use arrays instead of pointers.
18347 2001-12-05 Akim Demaille <akim@epita.fr>
18349 * src/lalr.c (maxrhs): Move to...
18350 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
18351 * src/lalr.c (build_relations): Adjust.
18353 2001-12-05 Akim Demaille <akim@epita.fr>
18355 * src/lalr.c (transpose): Free the memory allocated to the
18356 argument, as it is replaced by the results by the unique caller.
18357 (build_relations): Merely invoke transpose: it handles the memory
18359 Improve variable locality.
18360 Avoid variables used as mere abbreviations.
18361 (compute_lookaheads): Use arrays instead of pointers.
18363 2001-12-05 Akim Demaille <akim@epita.fr>
18365 * src/lalr.c (initialize_F): Improve variable locality.
18366 Avoid variables used as mere abbreviations.

18370 * src/derives.c (print_derives): Display the ruleno.
18371 * src/lalr.c (initialize_F, transpose): Better variable locality
18372 to improve readability.

18377 * src/lalr.c (traverse): Use arrays instead of pointers.
18379 2001-12-05 Akim Demaille <akim@epita.fr>
18381 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
18382 the handling of squeue.
18383 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
18385 2001-12-05 Akim Demaille <akim@epita.fr>
18387 Because useless nonterminals are now kept alive (instead of being
18388 `destroyed'), we now sometimes examine them, and store information
18389 related to them. Hence we need to know their number, and adjust
18390 memory allocations.
18392 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
18394 * src/LR0.c (allocate_itemsets): The memory allocated to
18395 `symbol_count' was used for two different purpose: once to count
18396 the number of occurrences of each symbol, and later reassigned to
18397 `shift_symbol', containing the symbol that can be shifted from a
18399 Deobfuscate, i.e., allocate, use and free `symbol_count' here
18401 (new_itemsets): Allocate `shift_symbol' here.
18402 (allocate_itemsets): symbol_count includes useless nonterminals.
18403 Make room for them.
18404 (free_storage): Use `free', not `XFREE', for pointers that cannot
18407 2001-12-05 Akim Demaille <akim@epita.fr>
18409 * src/nullable.c (set_nullable): Deobfuscate the handling of
18411 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
18413 2001-12-05 Akim Demaille <akim@epita.fr>
18415 * src/gram.c, src/gram.h (ritem_print): New.
18416 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
18417 (This useless function was defined only to work around VMS linkers
18418 that can't handle compilation units with variables only).
18419 * src/reduce.c (dump_grammar): Use it to trace the construction of
18422 2001-12-04 Paul Eggert <eggert@twinsun.com>
18424 * src/bison.simple (union yyalloc): Change member names
18425 to be the same as the stack names.
18426 (yyparse): yyptr is now union yyalloc *, not char *.
18427 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
18428 and may generate better code on some machines.
18429 (yystpcpy): Use prototype if __STDC__ is defined, not just
18430 if __cplusplus is defined.
18432 2001-11-30 Akim Demaille <akim@epita.fr>
18434 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
18435 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
18436 Gettext doesn't compile cleanly, and dies with -Werror.
18437 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
18438 Include WARNING_CFLAGS here.
18439 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
18440 before being defined.
18442 2001-11-27 Paul Eggert <eggert@twinsun.com>
18444 * lib/quotearg.h (quotearg_n, quotearg_n_style):
18445 First arg is int, not unsigned.
18446 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
18447 (SIZE_MAX, UINT_MAX): New macros.
18448 (quotearg_n_options): Abort if N is negative.
18449 Avoid overflow check on hosts where size_t is 64 bits and int
18450 is 32 bits, as overflow is impossible there.
18451 Fix off-by-one typo that caused unnecessary reallocation.
18453 2001-11-29 Paul Eggert <eggert@twinsun.com>
18455 Name space cleanup in generated parser.
18457 * doc/bison.texinfo (Bison Parser): Discuss system headers
18458 and their effect on the user name space.
18460 * src/bison.simple:
18461 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
18462 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
18463 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
18465 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
18466 on user names when possible.
18468 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
18469 Simplify test for whather <alloca.h> exists.
18471 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
18473 (<stdio.h>): Include if YYDEBUG.
18475 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
18476 ! defined (yyoverflow) && ! defined (yymemcpy).
18478 (yymemcpy, yyparse): Rename local variables as needed so that
18479 they all begin with 'yy'.
18481 (yystrlen, yystpcpy): New functions.
18483 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
18486 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
18487 instead of relying on string.h functions. Use YYSTACK_ALLOC
18488 and YYSTACK_FREE instead of malloc and free.
18490 2001-11-30 Akim Demaille <akim@epita.fr>
18492 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
18493 before their first uses.
18494 (YYBISON, YYPURE): Move to the top of the output.
18496 2001-11-30 Akim Demaille <akim@epita.fr>
18498 * tests/reduce.at (Useless Nonterminals): Fix.
18500 2001-11-30 Akim Demaille <akim@epita.fr>
18502 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
18503 if body instead of `;' to pacify GCC's warnings.
18505 2001-11-30 Akim Demaille <akim@epita.fr>
18507 Instead of mapping the LHS of unused rules to -1, keep the LHS
18508 valid, but flag the rules as invalid.
18510 * src/gram.h (rule_t): `useful' is a new member.
18511 * src/print.c (print_grammar): Adjust.
18512 * src/derives.c (set_derives): Likewise.
18513 * src/reader.c (packgram, reduce_output): Likewise.

18522 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
18524 2001-11-30 Akim Demaille <akim@epita.fr>
18526 * src/reduce.c (nonterminals_reduce): Instead of throwing away
18527 useless nonterminals, move them at the end of the symbol arrays.
18528 (reduce_output): Adjust.
18529 * tests/reduce.at (Useless Nonterminals): Adjust.

18541 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
18542 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
18544 (union yyalloc): New type.
18545 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
18546 an arbitrary restriction on hosts where size_t is wider than int.
18548 (yyparse): Don't dump core if alloca or malloc fails; instead, report
18549 a parser stack overflow. Allocate just one block of memory for all
18550 three stacks, instead of allocating three blocks; this typically is
18551 faster and reduces fragmentation.
18553 Do not limit the number of items in the stack to a value that fits
18554 in 'int', as this is an arbitrary limit on hosts with 64-bit
18555 size_t and 32-bit int.

20618 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
20619 s/PFILE1/BISON_HAIRY/.

20622 2000-11-03 Akim Demaille <akim@epita.fr>
20624 For some reason, this was not applied.
20626 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

20639 (done): Rename as...
20640 (output_files): this.
20641 Use `obstack_save'.
20642 * src/main.c (main): Don't use `atexit' to register `done', since
20643 it no longer has to remove tmp files, just call `output_files'
20644 when there are no errors.
20646 2000-11-02 Akim Demaille <akim@epita.fr>
20648 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
20649 `unlink': it's no longer used.
20650 * src/files.h: Formatting changes.
20652 2000-11-02 Akim Demaille <akim@epita.fr>
20654 Remove the last uses of mktemp and unlink/delete.
20656 * src/files.c (fdefines, ftable): Removed.
20657 (defines_ostack, table_obstack): New.

20716 * src/reader.c (copy_comment2): Expect the input stream to be on
20717 the `/' which is suspected to open a comment, instead of being
20718 called after `//' or `/*' was read.
20719 (copy_comment, copy_definition, parse_union_decl, copy_action)
20720 (copy_guard): Adjust.
20722 2000-10-16 Akim Demaille <akim@epita.fr>
20724 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

20748 2000-10-04 Akim Demaille <akim@epita.fr>
20750 When a literal string is used to define two different tokens,
20751 `bison -v' segfaults.
20752 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
20754 * tests/regression.m4: New file.
20755 Include the core of the sample provided by Piotr Gackiewicz.
20756 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
20759 2000-10-04 Akim Demaille <akim@epita.fr>
20761 * src/reader.c (parse_expect_decl): Keep `count' within the size
20765 2000-10-02 Paul Eggert <eggert@twinsun.com>
20767 * bison.s1 (yyparse): Assign the default value
20768 unconditionally, to avoid a GCC warning and make the parser a
20771 2000-10-02 Akim Demaille <akim@epita.fr>
20773 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
20776 2000-10-02 Akim Demaille <akim@epita.fr>
20778 * src/derives.c, src/print.c, src/reduce.c: To ease the
20779 translation, move some `\n' out of the translated strings.
20781 2000-10-02 Akim Demaille <akim@epita.fr>
20783 The location tracking mechanism is precious for parse error
20784 messages. Nevertheless, it is enabled only when `@n' is used in
20785 the grammar, which is a different issue (you can use it in error
20786 message, but not in the grammar per se). Therefore, there should
20787 be another means to enable it.
20789 * src/getargs.c (getargs): Support `--locations'.
20790 (usage): Report it.
20791 * src/getargs.h (locationsflag): Export it.
20792 * src/lex.c (percent_table): Support `%locations'.
20793 * src/reader.c (yylsp_needed): Remove this variable, now replaced
20794 with `locationsflag'.
20795 * doc/bison.texinfo: Document `--locations' and `%locations'.
20797 * tests/calc.m4: Test it.
20799 For regularity of the names, replace each
20800 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
20801 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
20802 In addition replace each `flag' with `_flag'.
20804 2000-10-02 Akim Demaille <akim@epita.fr>
20806 Also test parse error messages, including with YYERROR_VERBOSE.
20808 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
20810 Use it to check the computations.
20811 Use it to check `nonassoc' is honored.
20812 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
20813 `--yyerror-verbose'.
20814 (_AT_CHECK_CALC): Adjust to this option.
20815 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
20817 2000-10-02 Akim Demaille <akim@epita.fr>
20819 Test also `--verbose', `--defines' and `--name-prefix'. Testing
20820 the latter demonstrates a flaw in the handling of non debugging
20821 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
20822 was used in order to simplify:
20838 unfortunately this leads to a CPP conflict when
20839 `--name-prefix=foo' is used since it produces `#define yydebug
20842 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
20843 (YYDPRINTF): New macro.
20845 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
20847 Also test `--verbose', `--defines' and `--name-prefix'.
20849 2000-10-02 Akim Demaille <akim@epita.fr>
20851 Improve the readability of the produced parsers.
20853 * src/bison.s1: Formatting changes.
20854 Improve the comment related to the `$' mark.
20855 (yydefault): Don't fall through to `yyresume': `goto' there.
20856 * src/output.c (output_parser): When the `$' is met, skip the end
20858 New variable, `number_of_dollar_signs', to check there's exactly
20859 one `$' in the parser skeleton.
20861 2000-10-02 Akim Demaille <akim@epita.fr>
20863 * lib/xstrdup.c: New file, from the fileutils.
20864 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
20865 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
20866 instead of strlen + xmalloc + strcpy.
20867 * src/symtab.c (copys): Remove, use xstrdup instead.
20869 2000-10-02 Akim Demaille <akim@epita.fr>
20871 * src/gram.h (associativity): New enum type which replaces the
20872 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
20873 `right_assoc', `left_assoc' and `non_assoc'.
20874 Adjust all dependencies.
20875 * src/reader.c: Formatting changes.
20876 (LTYPESTR): Don't define it, use it as a literal in
20877 `reader_output_yylsp'.
20878 * src/symtab.h (symbol_class): New enum type which replaces the
20879 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
20880 `sunknown', `stoken and `snterm'.
20882 2000-10-02 Akim Demaille <akim@epita.fr>
20884 * src/getargs.c (fixed_outfiles): Rename as...
20885 (yaccflag): for consistency and accuracy.
20886 Adjust dependencies.
20888 2000-10-02 Akim Demaille <akim@epita.fr>
20890 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
20891 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
20892 difficult and introduced a lot of core dump. It turns out that
20893 Bison used an implementation of `xmalloc' based on `calloc', and
20894 at various places it does depend upon the initialization to 0. I
20895 have not tried to isolate the pertinent places, and all the former
20896 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
20897 someone should address this issue.
20899 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
20900 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

20908 Various anti-`extern in *.c' changes.
20910 * src/system.h: Include `assert.h'.
20912 2000-10-02 Akim Demaille <akim@epita.fr>
20914 * src/state.h (nstates, final_state, first_state, first_shift)
20915 (first_reduction): Move their exportation from here...
20916 * src/LR0.h: to here.
20917 Adjust dependencies.
20918 * src/getargs.c (statisticsflag): New variable.
20919 Add support for `--statistics'.
20920 Adjust dependencies.
20922 Remove a lot of now useless `extern' statements in most files.

20926 * src/LR0.h: New file.
20929 2000-10-02 Akim Demaille <akim@epita.fr>

20955 * src/reduce.h: New file.
20956 Propagate its inclusion.
20957 * src/reduce.c: Topological sort and other formatting changes.
20958 (bool, TRUE, FALSE): Move their definition to...
20959 * src/system.h: here.
20961 2000-10-02 Akim Demaille <akim@epita.fr>
20963 * src/files.c: Formatting changes.
20964 (tryopen, tryclose, openfiles): Rename as...
20965 (xfopen, xfclose, open_files): this.
20966 (stringappend): static.
20967 * src/files.h: Complete the list of exported symbols.

20990 * src/lalr.c: Formatting changes, topological sorting etc.
20992 2000-10-02 Akim Demaille <akim@epita.fr>
20994 * src/output.c (token_actions): Introduce a temporary array,
20995 YYDEFACT, that makes it possible for this function to use
20996 output_short_table.
20998 2000-10-02 Akim Demaille <akim@epita.fr>
21000 `user_toknums' is output as a `short[]' in `output.c', while it is
21001 defined as a `int[]' in `reader.c'. For consistency with the
21002 other output tables, `user_toknums' is now defined as a table of

21032 functions, use of closure.h.

21046 * src/system.h: Define PARAMS.

21267 Change the handling of @s so that they behave exactly like $s.
21268 There is now a pseudo variable @$ (readble and writable), location
21269 of the lhs of the rule (by default ranging from the location of
21270 the first symbol of the rhs, to the location of the last symbol,

21306 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
21307 One `#if YYDEBUG' remains, since it uses variables which are

21999 an invalid character. Do not abort.
22000 (read_declarations, copy_guard, copy_action): Use
22001 printable_version to avoid unprintable characters in printed output.

22030 always contain the token. This includes growing the token
22031 buffer while reading an integer.
22032 (parse_percent_token): Replaced if-else statement with percent_table.
22033 (parse_percent_token): Added % declarations as another
22034 way to specify the flags -n, -l, and -r. Also added hooks for
22035 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
22036 major changes to files.c.
22037 (lex) Retain in the incoming stream a character following
