9 * doc/bison.texinfo: Comment changes.
11 2009-09-16 Akim Demaille <demaille@gostai.com>
13 lalr1.cc: factor the yytranslate_ invocation in make_SYMBOLS.
14 * data/c++.m4, data/lalr1.cc (parser::symbol_type): Change the
15 constructor to take a token_type instead of the (internal) symbol
18 * data/variant.hh (b4_symbol_constructor_define_): Therefore,
19 don't call yytranslate_ here.
21 2009-09-16 Akim Demaille <demaille@gostai.com>
24 * TODO (Figures): New.
26 2009-09-13 Joel E. Denny <jdenny@clemson.edu>
28 tests: clean up push.at test group titles.
29 * tests/push.at: Remove "Push Parsing: " from test group titles
30 because these are already under the banner "Push Parsing Tests".
32 2009-09-12 Alex Rozenman <rozenman@gmail.com>
34 Provide an additional sub-message for clarity.
35 Add "symbol not found in production" error message when
36 an "invalid reference" is detected in named references
38 * src/scan-code.l: Update "invalid reference" case.
39 * tests/named-ref.at: Adjust test-cases.
41 2009-09-10 Joel E. Denny <jdenny@clemson.edu>
43 Clean up yacc.c a little.
44 * data/yacc.c: Clean up M4 for readability, and make output
45 whitespace more consistent. For the main parse function
46 comment, instead of saying "yyparse or yypush_parse", say either
47 "yyparse" or "yypush_parse" depending on which it actually is.
49 2009-09-10 Joel E. Denny <jdenny@clemson.edu>
51 Fix --enable-gcc-warnings.
52 * src/parse-gram.y (%printer <param>): Handle param_none.
54 2009-09-09 Akim Demaille <demaille@gostai.com>
56 lalr1.cc: syntax_error as exceptions.
57 It is common to use sort of factories in the user actions. These
58 factories may check some "syntactic" constraints that are not
59 enforced by the grammar itself. This is possible using YYERROR
60 within the action itself. Provide the user with a means to throw
61 a syntax_error exception.
63 * data/c++.m4 (b4_public_types_declare, b4_public_types_define):
64 Declare and define yy::parser::syntax_error.
65 * data/lalr1.cc: Include stdexcept.
66 (yy::parser::parse): Wrap the user action within a try/catch.
67 * data/glr.cc: Include stdexcept.
69 2009-09-09 Akim Demaille <demaille@gostai.com>
71 lalr1.cc: add missing "inline".
72 * data/c++.m4 (b4_public_types_define): Add missing inline to
73 implementations provided in headers.

112 * src/parse-gram.y (param_type): New.
113 Define a %printer for it.
115 (%parse-param, %lex-param): Merge into...
116 (%parse): this new token.
117 Adjust the grammar to use it.
118 * src/scan-gram.l (RETURN_VALUE): New.
119 (RETURN_PERCENT_FLAG): Use it.
120 (RETURN_PERCENT_PARAM): New.
121 Use it to support %parse-param, %lex-param and %param.
123 2009-09-03 Joel E. Denny <jdenny@clemson.edu>
126 * src/output.c: Don't include assert.h.
127 (output_skeleton): Use aver not assert.
128 * src/system.h (aver): In documentation of why, add links to
129 Paul Eggert's explanations in the mailing lists.
131 2009-09-05 Alex Rozenman <rozenman@gmail.com>
133 Use "Unresolved reference" error message when no symbols were found
134 in a symbolic reference resolution. Remove .expr and -expr from
135 the shown reference when the reference is unresolved.
136 * src/scan-code.l: Change the error message, adjust location columns,
137 rename variable "exact_mode" to "explicit_bracketing".
138 * tests/named-ref.at: Adjust existing tests and add a new one.
140 2009-09-04 Akim Demaille <demaille@gostai.com>
142 Adjust synclines in src/parse-gram.[ch].
143 * tests/bison.in: Do some magic (including working around issues
144 with ylwrap) when this wrapper is used to compile
147 2009-09-03 Joel E. Denny <jdenny@clemson.edu>
149 Complain about unused %define variables and %code qualifiers.
150 * NEWS (2.5): Document.
151 * data/bison.m4 (b4_check_user_names): Complain instead of warn.

153 improve %define documentation a little otherwise.
154 * tests/input.at (Reject unused %code qualifiers): Update.
155 (%define errors): Update.
156 (%define, --define, --force-define): Update.

161 2009-09-03 Joel E. Denny <jdenny@clemson.edu>
163 Don't suppress warnings about unused parse.error.
164 * data/bison.m4 (b4_error_verbose_flag): Don't examine value of
165 %define variable parse.error unless b4_error_verbose_flag is
166 actually expanded in a skeleton.
168 2009-09-03 Akim Demaille <demaille@gostai.com>
170 * NEWS (2.4.2): Add "Internationalization" item.
172 2009-09-03 Akim Demaille <demaille@gostai.com>
174 bootstrap: fix/improve find_tool.
175 * bootstrap (find_tool): Improve error messages.
176 Fix typo about find_tool_names.
178 2009-08-29 Joel E. Denny <jdenny@clemson.edu>
180 Fix gcc 3.4.4 shadowing warning reported by Eric Blake.
182 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00093.html>.
183 * src/scan-code.h (code_props_rule_action_init): Rename
184 named_ref arg to name so it doesn't shadow named_ref type. This
185 makes it consistent with the function definition in scan-code.l
188 2009-08-28 Joel E. Denny <jdenny@clemson.edu>
190 %define: accept unquoted values.
191 * NEWS (2.5): Group all %define changes together, and document
192 this one. Remove quotes in IELR and canonical LR entry.
193 * doc/bison.texinfo: Remove quotes in most examples throughout.

207 2009-08-28 Joel E. Denny <jdenny@clemson.edu>
209 %define lr.type: make values lowercase IDs.
210 That is, "LALR" => "lalr", "IELR" => "ielr", and
211 "canonical LR" => "canonical-lr".

225 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
226 Avoid compiler warning.
228 2009-08-27 Joel E. Denny <jdenny@clemson.edu>
230 tests: use perl for printing special sequences to files.
231 And skip tests if perl is not available. This is better than
232 playing tricks with shell portability. Suggested by Akim
234 * tests/input.at (Bad character literals): Use it here for
235 omitting final newlines.
236 (Bad escapes in literals): Use it here for special characters.
238 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
240 tests: show a use of %define lr.default-reductions "consistent"
241 * tests/conflicts.at (%nonassoc and eof): Extend to test that it
242 prevents the omission of expected tokens for %error-verbose.
244 2009-08-26 Akim Demaille <demaille@gostai.com>
246 tests: portability fix.
247 * tests/input.at (Bad escapes in literals): Don't expect "echo
248 '\0'" to output \ then 0.
250 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
252 Actually handle the yytable zero value correctly this time.
253 * data/bison.m4 (b4_integral_parser_tables_map): Don't mention
254 zero values in the YYTABLE comments.
255 * data/glr.c (yytable_value_is_error): Don't check for zero
257 * data/lalr1.cc (yy_table_value_is_error_): Likewise.
258 * data/yacc.c (yytable_value_is_error): Likewise.
259 * data/lalr1.java (yy_table_value_is_error_): Likewise.
260 (yysyntax_error): Fix typo in code: use yytable_ not yycheck_.
261 * src/tables.h: In header comments, explain why it's useless to
262 check for a zero value in yytable.
264 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
266 More fixes related to last two patches.
267 * data/bison.m4 (b4_integral_parser_tables_map): Fix YYTABLE
268 comments: zero indicates syntax error not default action.
269 * data/c.m4 (b4_table_value_equals): Comment that YYID must be
271 * data/glr.c (yyis_pact_ninf): Rename to...
272 (yypact_value_is_default): ... this.
273 (yyisDefaultedState): Update for rename.
274 (yyis_table_ninf): Rename to...
275 (yytable_value_is_error): ... this, and check for value zero
276 besides just YYTABLE_NINF.
277 (yygetLRActions): Check for default value from yypact. It
278 appears that this check is always performed before this function
279 is invoked, and so adding the check here is probably redundant.
280 However, the code may evolve after this subtlety is forgotten.
281 Also, update for rename to yytable_value_is_error. Because that
282 macro now checks for zero, a different but equivalent branch of
283 the if-then-else here is evaluated.
284 (yyreportSyntaxError): Update for rename to
285 yytable_value_is_error. The zero condition was mishandled
287 (yyrecoverSyntaxError): Update for renames. No behavioral
289 * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_):
291 (yy_table_value_is_error_): New function.
292 (parse): Use new functions where possible. No behavioral
294 (yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_.
295 The zero condition was mishandled before.
296 * data/yacc.c (yyis_pact_ninf): Rename to...
297 (yypact_value_is_default): ... this.
298 (yyis_table_ninf): Rename to...
299 (yytable_value_is_error): ... this, and check for value zero
300 besides just YYTABLE_NINF.
301 (yysyntax_error): Update for rename to yytable_value_is_error.
302 The zero condition was mishandled before.
303 (yyparse): Update for renames. No behavioral changes.
304 * src/tables.h: Improve comments about yypact, yytable, etc.
305 more. Most importantly, say yytable value of zero means syntax
306 error not default action.
308 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
310 Fix %error-verbose for conflicts resolved by %nonassoc.
311 * NEWS (2.5): Document.

318 * tests/conflicts.at (%nonassoc and eof): Update expected output
321 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
323 Some code and documentation improvements.
324 * data/c.m4 (b4_table_value_equals): New macro to capture
326 * data/glr.c (yyis_pact_ninf): Use it here.
327 (yyis_table_ninf): Likewise.
328 (yyreportSyntaxError): Improve internal comments.
329 * data/yacc.c (yyis_pact_ninf): New macro copied from glr.c.
330 Use it everywhere possible.
331 (yyis_table_ninf): Likewise.
332 (yysyntax_error): Improve internal comments.
333 * data/lalr1.cc (yysyntax_error_): Likewise.
334 * data/lalr1.java (yysyntax_error): Likewise.
335 * src/tables.h: Improve comments about yypact, yytable, etc.
337 2009-08-21 Joel E. Denny <jdenny@clemson.edu>
339 Use locale when quoting.
340 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER): Use
341 quote rather than implementing quoting here.
343 2009-08-20 Eric Blake <ebb9@byu.net>
345 Make previous patch more robust.
346 * src/output.c (ARRAY_CARDINALITY): New macro, copied from
348 (output_skeleton): Use it.
349 Suggested by Akim Demaille.
351 Import latest m4/m4.m4.
352 * submodules/autoconf: Update to autoconf 2.64.
353 * configure.ac (M4_GNU_OPTION): New define.
354 * src/output.c (output_skeleton): Use it to resolve FIXME.
355 * NEWS: Mention this.

359 Fix complaints about escape sequences.
360 Discussed starting at
361 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>.
362 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
363 For a \0 and similar escape sequences meaning the null
364 character, report an invalid escape sequence instead of an
365 invalid null character because the latter does not actually
366 appear in the user's input.
367 In all escape sequence complaints, don't escape the initial
368 backslash, and don't quote when the sequence appears at the end
369 of the complaint line unless there's whitespace that quotearg
371 Consistently say "invalid" not "unrecognized".
372 Consistently prefer "empty character literal" over "extra
373 characters in character literal" warning for invalid escape
374 sequences; that is, consistently discard those sequences.
375 * tests/input.at (Bad escapes in literals): New.
377 2009-08-19 Akim Demaille <demaille@gostai.com>
380 * doc/bison.texinfo: Fix minor Texinfo errors.
382 2009-08-19 Akim Demaille <demaille@gostai.com>
384 tests: distcc compliance.
385 * tests/synclines.at (AT_SYNCLINES_COMPILE): Discard distcc's
386 error messages from the output.
388 2009-08-19 Akim Demaille <demaille@gostai.com>
390 variables: simplify the upgrade of namespace into api.namespace.
392 This patch simplifies "variables: rename namespace as
393 api.namespace", commit 67501061076ba46355cfd9f9361c7eed861b389c.
394 Suggested by Joel E. Denny in
395 http://lists.gnu.org/archive/html/bison-patches/2009-07/msg00006.html
397 * src/muscle-tab.c (muscle_percent_variable_update): New.
398 (muscle_percent_define_insert): Use it in replacement of the
399 previous tr invocation.
400 Remove variable_tr, no longer needed.
401 * data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
403 * data/c++.m4: No longer handle namespace -> api.namespace.
404 * tests/input.at (%define backward compatibility): Check that
405 namespace is treated as api.namespace.
407 2009-08-19 Akim Demaille <demaille@gostai.com>
409 doc: %initial-action to initialize yylloc.
410 Reported by Bill Allombert.
411 * doc/bison.texinfo: Set fill-column to 76.
412 (Location Type): Document the use of %initial-action to initialize
415 2009-08-19 Akim Demaille <demaille@gostai.com>
417 lalr1.cc: use state_type.
418 * data/lalr1.cc (yysyntax_error_): Use state_type.
419 Move argument names into yy*.
421 2009-08-19 Akim Demaille <demaille@gostai.com>
423 lalr1.cc: get rid of yyparse's yystate.
424 yystate and yystack_[0].state are equal, keep only the latter.
425 The former was also used as a temporary variable to compute the
426 post-reduction state. Move this computation into an auxiliary
429 * data/glr.c (yyLRgotoState): Fuse variable definition and first
431 * data/lalr1.cc (yy_lr_goto_state_): New.
433 Replace remaining uses of yystate by yystate_[0].state.
436 2009-08-19 Akim Demaille <demaille@gostai.com>
438 lalr1.cc: destroy $$ when YYERROR is called.
439 * data/lalr1.cc (yyreduce): Compute the resulting state before
440 running the user action so that yylhs is a valid symbol.
441 (yyerrorlab): Since yylhs is complete (it knows its type), we can
442 simply call yy_destroy_ to destroy $$ on YYERROR invocations.
443 * tests/c++.at (AT_CHECK_VARIANTS): Test YYERROR with variants.
445 2009-08-18 Joel E. Denny <jdenny@clemson.edu>

456 build: require gettext 0.17.
458 Suggested by Bruno Haible.
459 http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00009.html
460 * configure.ac: require gettext 0.17 to ensure compatibility with
463 2009-08-17 Akim Demaille <demaille@gostai.com>
465 build: lower gettext requirements.
467 Bison was uselessly requiring the formatstring macros from
468 gettext, which resulted in mo files not being installed on systems
469 that perfectly supported Bison mo files. Lower the requirement.
470 http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html
472 * configure.ac: Require need-ngettext instead of
473 need-formatstring-macros.
474 Reported by Martin Jabocs.
475 Suggested by Bruno Haible.

490 Make it easier to write deterministic tests.
491 Continues Akim's work from his 2009-06-10 commits.
492 * src/reader.c (check_and_convert_grammar): Don't add any
493 symbols after the first symbols_do invocation.
494 * src/symtab.c (symbols_sorted): New static global.
495 (user_token_number_redeclaration): Update comments.
496 (symbol_from_uniqstr): If a new symbol is being created, assert
497 that symbols_sorted hasn't been allocated yet.
498 (symbols_free): Free symbols_sorted.
499 (symbols_cmp, symbols_cmp_qsort): New functions.
500 (symbols_do): Sort symbol_table into symbols_sorted on first
502 * tests/input.at (Numbered tokens): Recombine tests now that the
503 output should be deterministic across multiple numbers.
505 2009-08-12 Akim Demaille <demaille@gostai.com>
507 tests: GCC 4.5 compliance.
508 * tests/synclines.at (AT_SYNCLINES_COMPILE): Adjust to GCC 4.5's
509 messages about #error.
511 2009-08-12 Akim Demaille <demaille@gostai.com>
513 build: fix the generation of the documentation.
514 Some of our targets use "bison --help", but they can't depend on
515 "bison" itself (to avoid additional requirements on the user), so
516 they used to call "make src/bison" in the commands. Then
517 concurrent builds may fail: one make might be aiming one of its
518 jobs at compiling src/bison, and another job at generating the man
519 page. If the latter is faster than the former, then we have two
520 makes that concurrently try to compile src/bison.
522 This might also be a more convincing explanation for the failure
523 described in the patch "build: fix paths".
525 * Makefile.am (SUFFIXES): Initialize.
526 * build-aux/move-if-change: New, symlink to gnulib's.
527 * build-aux/local.mk: Ship it.

556 Make) is sometimes confused. As a result it may want to build
557 lib/libbison.la and $(top_builddir)/lib/libbison.la (the same
558 file, different names) concurrently, which, amusingly enough,
561 ranlib lib/libbison.a

576 2009-08-10 Joel E. Denny <jdenny@clemson.edu>
578 * tests/local.mk (TESTSUITE_AT): Add named-refs.at.
580 2009-08-10 Joel E. Denny <jdenny@clemson.edu>
582 Miscellaneous code readability improvements.
584 * src/reader.c (reader): Move %define front-end variable
585 defaults and checking into...
586 (prepare_percent_define_front_end_variables): ... this new
589 * src/scan-gram.l (INITIAL): For consistency with string
590 literals, don't store open quote on character literal. It's
591 discarded before returning anyway.
592 (SC_ESCAPED_CHARACTER): Similarly, don't store close quote.
593 Make length test more readable, and make the character stored
594 for an empty literal more obvious while consistent with the
597 * src/symtab.c, src/symtab.h: Rename USER_NUMBER_ALIAS to
598 USER_NUMBER_HAS_STRING_ALIAS throughout.
599 * src/symtab.c (symbol_make_alias): Remove comment from symtab.c
600 that is repeated in symtab.h. Improve argument names to make it
601 clear which side of the symbol-string alias pair is which.
602 (symbol_check_alias_consistency): Improve local variable names
603 for the same purpose.
604 * src/symtab.h (struct symbol): Make comments about aliases
606 (symbol_make_alias): Improve comments and argument name.
607 * src/output.c (token_definitions_output): Update for rename to
608 USER_NUMBER_HAS_STRING_ALIAS and improve comments about aliases.
610 2009-08-08 Alex Rozenman <rozenman@gmail.com>
612 Convert "misleading reference" messages to warnings.
613 * src/scan-code.l: New function 'show_sub_messages', more
615 * tests/named-ref.at: Adjust tests.

619 maint: run "make update-copyright"
621 2009-08-06 Joel E. Denny <jdenny@clemson.edu>
623 maint: make update-b4-copyright easier to use
624 * build-aux/update-b4-copyright: In warnings, report line
625 numbers rather than character positions.
626 * cfg.mk (update-copyright-local): Set to update-b4-copyright so
627 that update-copyright runs it.
630 2009-08-05 Joel E. Denny <jdenny@clemson.edu>
632 maint: clean up update-b4-copyright code
633 * build-aux/update-b4-copyright: Do not accept 2-digit
634 UPDATE_COPYRIGHT_YEAR, which was not handled correctly.
635 Don't accept a `[' in a b4_copyright argument.
636 Format code more consistently.
637 Don't assume b4*copyright never occurs.
639 2009-08-04 Joel E. Denny <jdenny@clemson.edu>
641 maint: automate b4_copyright updates.
642 * Makefile.am (update-b4-copyright): New target rule.
643 * build-aux/local.mk (EXTRA_DIST): Add update-b4-copyright.
644 * build-aux/update-b4-copyright: New.
645 * data/yacc.c: Remove stray characters around b4_copyright
648 2009-08-04 Joel E. Denny <jdenny@clemson.edu>
650 maint: automate annual package-wide copyright-year update.
651 * .x-update-copyright: New.
652 * Makefile.am (EXTRA_DIST): Remove maint.mk.
653 * bootstrap.conf (gnulib_modules): Add maintainer-makefile and
654 update-copyright. Remove gnumakefile, which is implied by
656 * cfg.mk (bootstrap-tools): Copy from old maint.mk.
658 * maint.mk: Remove, now copied from gnulib.
659 * examples/extexi: Add missing "(C)" in copyright statement so
660 update-copyright can recognize it.
661 * src/LR0.h: Likewise.
662 * src/print.h: Likewise.
663 * src/print_graph.h: Likewise.
664 * src/gram.c: Add missing comma in copyright statement.

673 2009-08-01 Joel E. Denny <jdenny@clemson.edu>
675 Pacify "gcc -Wunused" for the input function from Flex.
676 Reported by Alex Rozenman. This warning shows up with gcc-4.3.0
678 * src/scan-code.l: Add "%option noinput", which I cannot find in
679 the Flex manual, but which Flex has supported since at least as
680 far back as 2.5.4. However, if any of our developers still use
681 Flex 2.5.4, they'll need to stop configuring with
682 --enable-gcc-warnings because "%option noinput" didn't work
683 correctly until Flex 2.5.6.
684 * src/scan-gram.l: Likewise.
685 * src/scan-skel.l: Likewise.
687 2009-07-31 Alex Rozenman <rozenman@gmail.com>
689 Fix --enable-gcc-warnings problems.
690 * src/reader.c: Adjust variable names.
691 * src/scan-code.l: Fix prototypes and adjust names.

696 Fix a --enable-gcc-warnings problem.
697 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Actually use length
700 2009-07-24 Joel E. Denny <jdenny@ces.clemson.edu>
702 Warn about character literals not of length one.
703 * NEWS (2.5): Document.
704 * src/scan-gram.l (INITIAL): Remove comment that we don't check
706 (SC_ESCAPED_CHARACTER): Warn if length is wrong.
707 * tests/input.at (Bad character literals): New test group.
709 2009-07-24 Alex Rozenman <rozenman@gmail.com>
711 Fix some memory leaks.
712 * src/named-ref.c: Add a pointer check (named_ref_free).
713 * src/scan-code.l: New function (variant_table_free). Called in
715 * src/symlist.c: Call to named_ref_free (symbol_list_free).
717 2009-07-24 Joel E. Denny <jdenny@ces.clemson.edu>
719 * src/lalr.c (state_lookahead_tokens_count): Correct comment.
721 2009-07-22 Joel E. Denny <jdenny@ces.clemson.edu>
723 Some M4 cleanup in the testsuite.
724 Suggested by Eric Blake at
725 <http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00083.html>.
726 * tests/existing.at (_AT_TEST_EXISTING_GRAMMAR): Do not
727 complicate the code by distinguishing between a missing value
728 and an empty string value for an optional argument. This fix is
729 allowed by the similar fix in AT_TEST_TABLES_AND_PARSE below.
730 * tests/local.at (_AT_TEST_TABLES_AND_PARSE): Merge into...
731 (AT_TEST_TABLES_AND_PARSE): ... this now that the special
732 arguments are not needed because of the following changes.
734 Bison developers should use GNU M4 and should not use
735 POSIXLY_CORRECT when building the test suite, so do not
736 complicate the code by avoiding $10 and above.
737 Do not quote an empty string value for an optional argument, and
738 do not distinguish between a missing value and an empty string

758 * src/reader.c: Factoring: assign_named_ref function.
759 * src/scan-code.l: Factoring and style changes. Rename

761 Use "unsigned" type for variant index. Improve readablity.
762 * src/scan-gram.l: Change error messages and add comments.
763 * src/symlist.h: symbol_list_null: New function decl.

772 2009-06-29 Akim Demaille <demaille@gostai.com>
774 build: avoid concurrent extraction of calc++.
775 * examples/calc++/Makefile.am (calc.stamp): New.
776 Depend on it to create the sources of calc++ so that concurrent
777 builds don't launch several "extexi" in parallel.
778 Not only this is inefficient, this also builds incorrect sources
779 with several extractions mixed together.
781 2009-06-29 Akim Demaille <demaille@gostai.com>
784 * data/bison.m4: Move code related to specific variables after the
785 definition of the variable-maintaining macros so that we don't
786 "invoke" b4_percent_define_check_values before it is defined.
788 2009-06-29 Akim Demaille <demaille@gostai.com>
790 variables: parse.error
792 Implement, document, and test the replacement of %error-verbose

795 values of the parse.error variable.
796 Make "simple" its default value.

844 (b4_percent_define_use): New.
845 Use it where applicable.

848 Default the latter to the former.
849 * doc/bison.texinfo (Decl Summary): Document "namespace" as
851 Document api.namespace.
852 Use @samp to document %define uses, keep @code for identifiers.
854 * tests/c++.at, tests/input.at: Test api.namespace instead of
855 namespace. (The tests passed with namespace.)

979 2009-05-19 Joel E. Denny <jdenny@ces.clemson.edu>
981 Handle a trailing `:' in a user-supplied C++ namespace better.
982 * data/c++.m4 (b4_namespace_close): Don't let it be printed
983 among the closing braces here. This fix might make the
984 generated code easier to debug, but otherwise it should be
985 insignificant because a trailing `:' is a C++ error already.

989 remove useless variable.

1593 2009-03-02 Akim Demaille <demaille@gostai.com>
1595 Use locations in the variant example.
1596 Yes, this obfuscates the point of this example, variants only.
1597 But glr.cc cannot work (yet?) without locations. This change
1598 makes it easier to use this example with glr.cc.
1600 * examples/variant.yy (assert): %define it.
1601 (locations): Request them.
1602 (yylex): Bind the location to the stage.

1614 * data/variant.hh: here.
1615 Remove the "b4_variant_if" parts, as variant.hh is loaded only if
1617 * data/lalr1.cc: No longer invoke b4_symbol_constructor_define and
1618 b4_symbol_constructor_declare, as it is now done by
1619 b4_public_types_define and b4_public_types_declare.

1713 Make yyparser::error public.
1714 * data/lalr1.cc: here.
1715 There is no good reason to keep it private (and it is convenient
1716 to use it from the scanner for instance). It is already public in
1719 2009-02-19 Akim Demaille <demaille@gostai.com>
1722 * data/glr.cc: here.
1724 2009-02-19 Akim Demaille <demaille@gostai.com>

1817 2008-12-11 Akim Demaille <demaille@gostai.com>
1819 Simplify the i18n of the error messages.
1820 * data/lalr1.cc: Comment changes.
1821 * data/yacc.c (yysyntax_error): Rewrite, using a switch as in

1824 2008-12-08 Akim Demaille <demaille@gostai.com>
1826 Fix portability issue in the test suite.
1827 * tests/local.at (AT_MATCHES_CHECK): New.
1828 Based on Perl instead of Sed. Sed has too many portability
1829 pitfalls, not ever Sed is GNU Sed.

1858 Fix regeneration of atconfig.
1859 * tests/local.mk (tests/atconfig): The rule was incorrect, but
1860 remove it: now that there is no tests/Makefile.am, the top-level
1861 Makefile properly updates atconfig when needed.
1863 2008-12-07 Di-an Jan <dianj@freeshell.org>
1865 Implement the FIXME that ends an user action with a semicolon
1866 if it seems necessary.
1867 * src/scan-code.l (flex rules section): Flag cpp directive from
1868 any `#' to the first unescaped end-of-line. Semicolon is not
1869 needed after `;', `{', '}', or cpp directives and is needed after
1870 any other token (whitespaces and comments have no effect).
1871 * tests/actions.at (Fix user actions without a trailing semicolon):
1873 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add semicolons to
1874 to make user actions complete statements.

1890 2008-12-02 Eric Blake <ebb9@byu.net>
1892 Build testsuite with newer autoconf.
1893 * tests/output.at (m4_expand): Don't override in newer autoconf,
1894 where the underlying implementation changed.
1895 * tests/cxx-type.at (_AT_RESOLVED_GLR_OUTPUT)
1896 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT)
1897 (_AT_AMBIG_GLR_OUTPUT_WITH_LOC, _AT_GLR_STDERR)
1898 (_AT_VERBOSE_GLR_STDERR): Expand to double-quoted strings,
1899 since some of them contain unbalanced ')'.
1901 2008-12-01 Akim Demaille <demaille@gostai.com>
1903 Use b4_symbol for printers and destructors everywhere.
1904 * data/bison.m4 (b4_symbol_action_location): New.
1905 * data/c.m4 (b4_symbol_actions): Remove.
1906 Adjust all callers to use by b4_symbol_foreach and the corresponding

1908 * data/glr.cc: Adjust.
1909 * data/lalr1.java: Adjust the %destructor sanity check.
1910 * src/output.c (symbol_code_props_output): Remove, we no longer
1911 need the b4_symbol_printers/destructors tables.
1913 2008-12-01 Akim Demaille <demaille@gostai.com>
1915 Use b4_symbol_case_.
1916 * data/lalr1.cc, data/bison.m4 (b4_symbol_action): Use
1919 2008-12-01 Akim Demaille <demaille@gostai.com>
1921 Move b4_symbol based macro to bison.m4.
1922 * data/lalr1.cc (b4_symbol_, b4_symbol, b4_symbol_if)
1923 (b4_symbol_action, b4_symbol_destructor, b4_symbol_printer)
1924 (b4_symbol_case_, b4_symbol_foreach, b4_type_action_)
1925 (b4_type_foreach): Move to...
1926 * data/bison.m4: Here.
1927 * data/lalr1.cc (b4_symbol_action): Specialize for C++: use
1928 b4_symbol_value_template instead of b4_symbol_value.
1930 2008-12-01 Akim Demaille <demaille@gostai.com>
1932 b4_symbol/type_foreach.
1933 * data/lalr1.cc (b4_symbol_foreach, b4_type_foreach): New.
1936 2008-12-01 Akim Demaille <demaille@gostai.com>
1938 Use the symbol properties to output the printer/destructor for lalr1.cc.
1939 Instead of defining complex list of tuples to define various
1940 properties of the symbols, we now prefer to define symbols as
1941 "structs" in m4: using the symbol key (its number), and the
1942 property name, b4_symbol gives it value. Use this to handle
1943 destructors and printers.
1945 * src/output.c (CODE_PROP): New.
1946 (prepare_symbol_definitions): Use it to define the printer and
1947 destructor related attributes of the symbols.
1948 * data/lalr1.cc (b4_symbol_actions): Rename as...
1949 (b4_symbol_action): this.
1950 Use b4_symbol instead of 6 arguments.
1951 (b4_symbol_printer, b4_symbol_destructor): New.
1952 Use them instead of b4_symbol_actions.
1954 2008-12-01 Akim Demaille <demaille@gostai.com>
1956 Avoid capturing variables too easily.
1957 * src/muscle_tab.h (MUSCLE_INSERT_BOOL, MUSCLE_OBSTACK_SGROW): Use
1958 v__ and p__ instead of v and p.

1962 Remove spurious empty line before syncline.
1963 * data/bison.m4 (b4_syncline): Don't output an empty line before
1966 2008-11-26 Akim Demaille <demaille@gostai.com>
1968 Convert lib/Makefile.am into lib/local.mk.
1969 The real problem is rather gnulib.mk, which itself is extracted
1970 from a Makefile.am that gnulib expects to the "recursive". The
1971 tool prefix-gnulib-mk converts such a gnulib.mk to be
1972 non-recursive. Also, some AC_SUBST variables need to be adjusted.
1974 * etc/prefix-gnulib-mk: New.
1975 * bootstrap (slurp): Use it to convert further gnulib.mk.
1976 No longer try to avoid re-creation of lib/gnulib.mk as the changes
1978 * lib/Makefile.am: Rename as...
1979 * lib/local.mk: this.
1980 Adjust to be prefixed.
1981 * Makefile.am, configure.ac: Adjust.
1982 * src/local.mk (AM_CPPFLAGS): Extend it, don't define it.
1984 2008-11-26 Akim Demaille <demaille@gostai.com>
1987 * tests/local.mk (TESTSUITE_FLAGS, AUTOTEST_FLAGS): Rename as...
1988 (TESTSUITEFLAGS, AUTOTESTFLAGS): these to compy with the GCS.
1989 Reported by Eric Blake.
1991 2008-11-26 Akim Demaille <demaille@gostai.com>
1993 Use b4_parser_tables_define in glr.cc.
1994 * data/glr.c: Use b4_parser_tables_define instead of defining the
1995 (deterministic integral) tables by hand.
1997 2008-11-26 Akim Demaille <demaille@gostai.com>
1999 Use b4_parser_tables_define in Java.
2000 * data/java.m4 (b4_typed_parser_table): Rename as...
2001 (b4_typed_parser_table_define): this, for consistency.
2002 Accept a comment as $4.
2004 (b4_integral_parser_table): Rename as...
2005 (b4_integral_parser_table_define): this.
2006 * data/lalr1.java: Adjust all uses.

2014 (b4_integral_parser_tables_map, b4_parser_tables_declare)
2015 (b4_parser_tables_define): these.
2016 * data/c.m4 (b4_table_define): Rename as...
2017 (b4_integral_parser_table_define): this.
2018 * data/lalr1.cc: Adjust.
2019 (b4_table_define, b4_table_declare): Rename as...
2020 (b4_integral_parser_table_define)
2021 (b4_integral_parser_table_declare): these.
2022 (yyrline_): Move the comment where it is actually used.
2023 * data/yacc.c: Adjust.
2024 (yyrline): Use b4_integral_parser_table_define.
2026 2008-11-26 Akim Demaille <demaille@gostai.com>
2029 * src/parse-gram.h, src/parse-gram.c: Regen.
2031 2008-11-26 Akim Demaille <demaille@gostai.com>
2033 Factor the generation of the (integral) tables bw yacc.c and lalr1.cc.
2034 * data/lalr1.cc (b4_tables_map): Move to...
2035 * data/bison.m4: here.
2036 Update the comment for yytable during the flight.
2037 (b4_tables_declare, b4_tables_define): New.
2038 * data/lalr1.cc: Use them.
2039 * data/c.m4 (b4_table_define): New.
2040 * data/yacc.c: Use b4_tables_define instead of output the tables
2042 * tests/regression.at (Web2c Actions): Adjust the expected output,
2043 the order of the tables changed.
2045 2008-11-26 Akim Demaille <demaille@gostai.com>
2047 Get rid of (yy)rhs and (yy)prhs.
2048 These tables are no longer needed in the parsers, and they don't seem to
2049 be useful. They are not documented either.
2051 * src/output.c (prepare_rules): Get rid of rhs and prhs.
2052 Adjust the computation of (yy)r2.
2054 2008-11-26 Akim Demaille <demaille@gostai.com>
2056 Rule length is unsigned.
2057 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
2059 2008-11-26 Akim Demaille <demaille@gostai.com>
2061 Get rid of lalr1-split.cc.
2062 It was no longer maintainer.
2064 * data/lalr1-split.cc: Remove.
2065 * etc/bench.pl.in (bench_fusion_parser): Remove.
2068 2008-11-26 Akim Demaille <demaille@gostai.com>
2070 Use yy* consistently.
2071 * data/glr.c: Now that yyrhs no longer exists as a global
2072 variable, rename local "rhs" variables into "yyrhs" for
2075 2008-11-25 Akim Demaille <demaille@gostai.com>
2077 Get rid of yyrhs and yyprhs in glr.c.
2078 * data/glr.c (yyrhs, yyprhs): Remove.
2079 Instead, use the state stack and yystos.
2081 2008-11-25 Akim Demaille <demaille@gostai.com>
2084 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
2085 as an Autotest keyword.
2087 2008-11-25 Akim Demaille <demaille@gostai.com>
2089 Prefer TESTSUITE_FLAGS.
2090 TESTSUITEFLAGS is barely readable.
2092 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
2093 for backward compatibility.
2094 Use the former instead of the latter.
2096 2008-11-25 Akim Demaille <demaille@gostai.com>
2098 Get rid of yyrhs and yyprhs in larl1.java.
2099 * data/lalr1.java (yyrhs_, yyprhs_): Remove.
2100 (yy_reduce_print): Rather, use yystos_ and the state stack.
2102 2008-11-25 Akim Demaille <demaille@gostai.com>
2106 2008-11-25 Akim Demaille <demaille@gostai.com>
2108 Get rid of yyrhs and yyprhs in yacc.c.
2109 They were used to get the symbol types, given a rule number, when
2110 displaying the top of the stack before a reduction. But the
2111 symbol type is available from the state stack. This has two be
2112 benefits: two tables less in the parser (making it smaller), and a
2113 more consistent use of the three stacks which will help to fuse
2116 * data/yacc.c (yyprhs, yyrhs): Remove.
2117 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
2118 (yy_reduce_print): Take yyssp as argument.
2119 Use it, together with yystos, to get the symbol type.
2120 * tests/regression.at (Web2c Report): Remove these tables from the
2123 2008-11-25 Akim Demaille <demaille@gostai.com>
2126 The point is to factor the generation of the tables across skeletons.
2127 This is language dependant.
2129 * data/c.m4 (b4_comment_): New.
2130 Should be usable to define how to generate tables independently of

2133 (b4_comment): Bounce to b4_c_comment.
2134 Now support $2 = [PREFIX] for indentation.

2150 (b4_table_define): Declare a third arg to match b4_table_declare
2152 Move all the comments around invocations of b4_table_define into
2153 the invocations itselves.

2307 2008-11-15 Akim Demaille <demaille@gostai.com>
2309 Support parametric types.
2311 There are two issues to handle: first scanning nested angle
2312 bracket pairs to support types such as std::pair< std::string,
2313 std::list<std::string> > >.
2315 Another issue is to address idiosyncracies of C++: do not glue two
2316 closing angle brackets together (otherwise it's operator>>), and
2317 avoid sticking blindly a TYPE to the opening <, as it can result
2318 in '<:' which is a digraph for '['.
2320 * src/scan-gram.l (brace_level): Rename as...
2323 Implement support for complex tags.
2326 * data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)
2327 (b4_symbol_variant): Leave space around types as parameters.
2328 * examples/variant.yy: Use nested template types and leading ::.
2329 * src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):
2331 (TAG, TAG_ANY, TAG_NONE, tag.opt): these.
2332 * tests/c++.at: Test parametric types.
2334 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
2337 This is not sufficient, but we test at least that the make_SYMBOL
2338 interface is not affected by token.prefix. A more general test
2339 will be implemented when the support of token.prefix is generalized

2416 Move sc_tight_scope into maint.mk.
2417 It does not work, and I don't know how it was supposed to work: it
2418 seems to be looking for sources in the build tree. I just moved
2419 it at a better place, fixing it is still required.

2443 * Makefile.am, configure.ac: Adjust.
2444 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on

2498 Provide convenience constructors for locations and positions.
2499 * data/location.cc (position::position): Accept file, line and

2501 Always qualify initial line and column literals as unsigned.
2502 (location::location): Provide convenience constructors.

2506 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
2508 Using template buys us nothing, and makes it uselessly complex to
2509 construct a symbol. Besides, it could not be generalized to other
2510 languages, while make_FOO would work in C/Java etc.
2512 * data/lalr1.cc (b4_symbol_): New.
2513 (b4_symbol): Use it.
2514 (b4_symbol_constructor_declaration_)
2515 (b4_symbol_constructor_definition_): Instead of generating
2516 specializations of an overloaded template function, just generate
2517 several functions whose names are forged from the token names
2518 without the token.prefix.
2519 (b4_symbol_constructor_declarations): Generate them for all the
2520 symbols, not just by class of symbol type, now that instead of
2521 specializing a function template by the token, we generate a
2522 function named after the token.
2523 (b4_symbol_constructor_specialization_)
2524 (b4_symbol_constructor_specializations): Remove.
2525 * etc/bench.pl.in: Adjust to this new API.
2527 2008-11-13 Akim Demaille <demaille@gostai.com>
2529 %define token.prefix.
2530 Provide a means to add a prefix to the name of the tokens as
2531 output in the generated files. Because of name clashes, it is
2532 good to have such a prefix such as TOK_ that protects from names
2533 such as EOF, FILE etc. But it clutters the grammar itself.
2535 * data/bison.m4 (token.prefix): Empty by default.
2536 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
2537 * data/lalr1.cc (b4_symbol): Ditto.
2539 2008-11-13 Akim Demaille <demaille@gostai.com>
2541 Compute at M4 time some of the subtractions.
2542 * data/lalr1.cc (b4_subtract): New.
2543 (b4_rhs_data): Use it.
2545 2008-11-13 Akim Demaille <demaille@gostai.com>
2548 This allows the user to get the type of a token returned by yylex.
2550 * data/lalr1.cc (symbol::token): New.
2551 (yytoknum_): Define when %define lex_symbol, independently of
2553 (yytoken_number_): Move into...
2554 (symbol::token): here, since that's the only use.
2555 The other one is YYPRINT which was not officially supported
2556 by lalr1.cc, and anyway it did not work since YYPRINT uses this
2557 array under a different name (yytoknum).
2559 2008-11-13 Akim Demaille <demaille@gostai.com>

2569 2008-11-13 Akim Demaille <demaille@gostai.com>
2572 * data/lalr1.cc, data/yacc.c: Fix the description of the
2573 yytranslate and yytoknum tables.
2575 2008-11-13 Akim Demaille <demaille@gostai.com>
2577 Define make_symbol in the header.
2578 To reach good performances these functions should be inlined (yet
2579 this is to measure precisely). To this end they must be available
2582 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
2583 location_type with the class name.
2584 Since will now be output in the header, declare "inline".
2585 No longer use b4_symbol_constructor_specializations, but
2586 b4_symbol_constructor_definitions in the header.
2587 Don't call it in the *.cc file.
2589 2008-11-13 Akim Demaille <demaille@gostai.com>
2591 Define yytranslate in the header for lex_symbol.
2592 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
2593 into the header file when using %define lex_symbol.
2594 (yytranslate_): Declare inline.
2596 2008-11-13 Akim Demaille <demaille@gostai.com>
2598 Define the constructors of symbol_type in
2599 b4_symbol_constructor_definitions.
2600 The constructors are called by the make_symbol functions, which a
2601 forthcoming patch will move elsewhere. Hence the interest of
2602 putting them together.
2604 The stack_symbol_type does not need to be moved, it is used only
2607 * data/lalr1.cc: Move symbol_type and symbol_base_type
2608 constructors into...
2609 (b4_symbol_constructor_definitions): here.
2612 2008-11-13 Akim Demaille <demaille@gostai.com>
2614 Make it easier to move the definition of yytranslate_.
2615 Forthcoming changes will make it possible to use yytranslate_
2616 from outside the parser implementation file.
2618 * data/lalr1.cc (b4_yytranslate_definition): New.
2621 2008-11-13 Akim Demaille <demaille@gostai.com>
2623 Remove useless class specification.
2624 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
2625 to refer to the class name to use a type defined by the class for
2626 arguments of member functions.
2628 2008-11-13 Akim Demaille <demaille@gostai.com>
2630 Finer input type for yytranslate.
2631 This patch is debatable: the tradition expects yylex to return an int
2632 which happens to correspond to token_number (which is an enum). This
2633 allows for instance to return characters (such as '*' etc.). But this
2634 goes against the stronger typing I am trying to have with the new
2635 lex interface which return a symbol_type. So in this case, feed
2636 yytranslate_ with a token_type.
2638 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
2639 expect a token_type.
2641 2008-11-13 Akim Demaille <demaille@gostai.com>
2643 Honor lex-params in %define lex_symbol mode.
2644 * data/lalr1.cc: Use b4_lex_param.
2646 2008-11-13 Akim Demaille <demaille@gostai.com>
2649 * src/output.c (symbol_definitions_output): Rename symbol
2650 attributes type_name and has_type_name as type and has_type.
2651 * data/lalr1.cc: Adjust uses.
2653 2008-11-13 Akim Demaille <demaille@gostai.com>
2655 Use b4_type_names for the union type.
2656 The union used to compute the size of the variant used to iterate
2657 over the type of all the symbols, with a lot of redundancy. Now
2658 iterate over the lists of symbols having the same type-name.
2660 * data/lalr1.cc (b4_char_sizeof_): New.
2661 (b4_char_sizeof): Use it.
2662 Adjust to be called with a list of numbers instead of a single
2664 Adjust its caller for new-line issues.
2666 2008-11-13 Akim Demaille <demaille@gostai.com>
2668 Define the "identifier" of a symbol.
2669 Symbols may have several string representations, for instance if
2670 they have an alias. What I call its "id" is a string that can be
2671 used as an identifier. May not exist.
2673 Currently the symbols which have the "tag_is_id" flag set are
2674 those that don't have an alias. Look harder for the id.
2676 * src/output.c (is_identifier): Move to...
2677 * src/symtab.c (is_identifier): here.
2678 * src/symtab.h, src/symtab.c (symbol_id_get): New.
2679 * src/output.c (symbol_definitions_output): Use it to define "id"
2681 Remove the definition of "tag_is_id".
2682 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
2683 "tag_is_id" were used to produce code.
2684 We still use "tag" for documentation.
2686 2008-11-11 Akim Demaille <demaille@gostai.com>
2688 Locations are no longer required by lalr1.cc.
2689 * data/lalr1.cc (_b4_args, b4_args): New.
2690 Adjust all uses of locations to make them optional.

2693 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
2694 without locations with lalr1.cc.
2696 * tests/output.at: Check lalr1.cc with and without location
2698 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
2699 Don't use locations.
2701 2008-11-11 Akim Demaille <demaille@gostai.com>
2704 * tests/local.at (AT_FULL_COMPILE): New.

2733 Support i18n of the parse error messages.
2734 * TODO (lalr1.cc/I18n): Remove.
2735 * data/lalr1.cc (yysyntax_error_): Support the translation of the
2736 error messages, as done in yacc.c.
2737 Stay within the yy* pseudo namespace.
2739 2008-11-11 Akim Demaille <demaille@gostai.com>
2742 * TODO (single stack, yysyntax_error): New.
2744 2008-11-11 Akim Demaille <demaille@gostai.com>
2746 Make it possible to return a symbol_type from yylex.
2747 * data/lalr1.cc (b4_lex_symbol_if): New.
2748 (parse): When lex_symbol is defined, expected yylex to return the
2750 * etc/bench.pl.in (generate_grammar_list): Extend to support this
2752 (bench_variant_parser): Exercise it.
2754 2008-11-11 Akim Demaille <demaille@gostai.com>
2756 Remove useless bench case.

2792 yychar cannot be empty in yyerrlab.

2807 Less memory pressure on the "list" bench.
2808 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
2809 the values, to limit memory pressure.
2811 2008-11-11 Akim Demaille <demaille@gostai.com>
2813 Introduce make_symbol.
2814 make_symbol provides a means to construct a full symbol (kind,
2815 value, location) in a single shot. It is meant to be a Symbol
2816 constructor, parameterized by the symbol kind so that overloading
2817 would prevent incorrect kind/value pairs. Unfortunately
2818 parameterized constructors do not work well in C++ (unless the
2819 parameter also appears as an argument, which is not acceptable),
2820 hence the use of a function instead of a constructor.
2822 * data/lalr1.cc (b4_symbol_constructor_declaration_)
2823 (b4_symbol_constructor_declarations)
2824 (b4_symbol_constructor_specialization_)
2825 (b4_symbol_constructor_specializations)
2826 (b4_symbol_constructor_definition_)
2827 (b4_symbol_constructor_definitions): New.
2828 Use them where appropriate to generate declaration, declaration of
2829 the specializations, and implementations of the templated
2830 overloaded function "make_symbol".
2831 (variant::variant): Always define a default ctor.
2832 Also provide a copy ctor.
2833 (symbol_base_type, symbol_type): New ctor overloads for value-less
2835 (symbol_type): Now public, so that functions such as yylex can use
2838 2008-11-11 Akim Demaille <demaille@gostai.com>
2840 Inform m4 whether a tag is a valid id.
2841 * src/output.c (is_identifier): New.
2842 (symbol_definitions_output): Use it to define tag_is_id.
2843 But maybe this should be done at m4 level?
2845 2008-11-11 Akim Demaille <demaille@gostai.com>
2847 Test 214 was failing: it greps with a pattern containing [ ]*
2848 which obviously meant to catch spaces and tabs, but contained only
2849 spaces. Tabulations in sources are a nuisance, so to simplify the
2850 matter, get rid of all the tabulations in the Java sources. The
2851 other skeletons will be treated equally later.
2853 * data/java.m4, data/lalr1.java: Untabify.
2854 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
2855 tabulations are no longer generated.
2857 2008-11-11 Paolo Bonzini <bonzini@gnu.org>
2859 * bootstrap.conf: Replace m4/warning.m4 with warnings module.
2860 * configure.ac: Adjust usage.
2861 * lib/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
2862 * src/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
2863 * tests/atlocal.in: Replace $(WARNING_*FLAGS) with $(WARN_*FLAGS).
2865 2008-11-10 Di-an Jan <dianj@freeshell.org>
2867 Workaround Java's ``code too large'' problem for parser tables
2868 in most cases, by using one function per initialization.
2869 * data/java.m4 (b4_typed_parser_table, b4_integral_parser_table): New.
2870 * data/lalr1.java (yypact_, yydefact_, yypgoto_, yydefgoto_,
2871 yytable_, yycheck_, yystos_, yytoken_number_, yyr1_, yyr2_, yyrhs_

2881 General Java skeleton improvements.
2882 * configure.ac (gt_JAVACOMP): Request target of 1.4, which allows
2883 using gcj < 4.3 in the testsuite, according to comments in
2884 gnulib/m4/javacomp.m4.
2885 * data/java.m4 (stype, parser_class_name, lex_throws, throws,
2886 location_type, position_type): Remove extraneous brackets from
2887 b4_percent_define_default.
2888 (b4_lex_param, b4_parse_param): Remove extraneous brackets from
2889 m4_define and m4_define_default.
2890 * data/lalr1.java (b4_pre_prologue): Change to b4_user_post_prologue,
2891 which marks the end of user code with appropriate syncline, like all
2892 the other skeletons.
2893 (b4_user_post_prologue): Add. Don't silently drop.
2895 (parse): Inline yylex.
2896 * doc/bison.texinfo (bisonVersion, bisonSkeleton): Document.
2897 (%{...%}): Fix typo of %code imports.
2898 * tests/java.at (AT_JAVA_COMPILE): Add "java" keyword.
2900 Support annotations on parser class with %define annotations.

2913 * doc/bison.texinfo (Java Bison Interface): Remove the parts
2914 about %error-verbose having no effect.
2915 (getErrorVerbose, setErrorVerbose): Document.
2917 Move constants for token names to Lexer interface.
2918 * data/lalr1.java (Lexer): Move EOF, b4_token_enums(b4_tokens) here.
2919 * data/java.m4 (b4_token_enum): Indent for move to Lexer interface.
2920 (parse): Qualify EOF to Lexer.EOF.
2921 * doc/bison.texinfo (Java Parser Interface): Move documentation of
2922 EOF and token names to Java Lexer Interface.
2923 * tests/java.at (_AT_DATA_JAVA_CALC_Y): Remove Calc qualifier.
2925 Make yyerror public.
2926 * data/lalr1.java (Lexer.yyerror): Use longer parameter name.
2927 (yyerror): Change to public. Add Javadoc comments. Use longer
2928 parameter names. Make the body rather than the declarator
2929 conditional on %locations.
2930 * doc/bison.texinfo (yyerror): Document. Don't mark as protected.
2932 Allow user to add code to the constructor with %code init.

2947 (associativity): Same precedence must have the same associativity.
2948 For instance, how can a * b / c be parsed if * is %left and / is
2950 (YYERRORCODE, YYFAIL, YYBACKUP): New.
2952 2008-11-10 Akim Demaille <demaille@gostai.com>
2956 2008-11-10 Akim Demaille <demaille@gostai.com>
2958 More information about the symbols.
2959 * src/output.c (type_names_output): Document all the symbols,
2960 including those that don't have a type-name.
2961 (symbol_definitions_output): Define "is_token" and
2963 * data/lalr1.cc (b4_type_action_): Skip symbols that have an empty
2964 type-name, now that they are defined too in b4_type_names.
2966 2008-11-10 Akim Demaille <demaille@gostai.com>
2970 2008-11-10 Akim Demaille <demaille@gostai.com>
2972 Make parser::yytranslate static.
2973 Small speedup (1%) on the list grammar. And makes yytranslate_
2974 available in non member functions.
2976 * data/lalr1.cc (yytranslate_): Does not need to be a instance
2979 2008-11-10 Akim Demaille <demaille@gostai.com>
2981 Avoid trailing spaces.
2982 * data/c.m4: b4_comment(TEXT): Don't indent empty lines.
2983 * data/lalr1.cc: Don't indent before rule and symbol actions, as
2984 they can be empty, and anyway this incorrectly indents the first
2987 2008-11-10 Akim Demaille <demaille@gostai.com>
2991 2008-11-10 Akim Demaille <demaille@gostai.com>
2993 Use "enum" for integral constants.
2994 This is just nicer to read, I observed no speedup.

2997 (yterror_, yyerrcode_, yyntokens_): Define as members of an enum.
2998 (yyuser_token_number_max_, yyundef_token_): Move into...

3007 Create the benches in "benches/".
3009 2008-11-10 Akim Demaille <demaille@gostai.com>

3033 2008-11-10 Akim Demaille <demaille@gostai.com>
3035 Change the handling of the symbols in the skeletons.
3036 Before we were using tables which lines were the symbols and which
3037 columns were things like number, tag, type-name etc. It is was
3038 difficult to extend: each time a column was added, all the numbers had
3039 to be updated (you asked for colon $2, not for "tag"). Also, it was
3040 hard to filter these tables when only a subset of the symbols (say the
3041 tokens, or the nterms, or the tokens that have and external number
3042 *and* a type-name) was of interest.
3044 Now instead of monolithic tables, we define one macro per cell. For
3045 instance "b4_symbol(0, tag)" is a macro name which contents is
3046 self-decriptive. The macro "b4_symbol" provides easier access to
3049 * src/output.c (type_names_output): Remove.
3050 (symbol_numbers_output, symbol_definitions_output): New.
3051 (muscles_output): Call them.
3052 (prepare_symbols): Define b4_symbols_number.

3075 * examples/variant.yy: Formatting changes.
3078 2008-11-10 Akim Demaille <demaille@gostai.com>

3081 This improves the "list" bench by 2%.
3083 * data/lalr1.cc (variant::build): Add an overloaded version with
3085 * tests/c++.at (AT_CHECK_VARIANT): Check it.
3087 2008-11-10 Akim Demaille <demaille@gostai.com>
3090 * tests/c++.at (AT_CHECK_VARIANTS): New.
3091 Use it with and without %define assert.
3093 2008-11-10 Akim Demaille <demaille@gostai.com>
3095 Add %precedence support.
3096 Unfortunately it is not possible to reuse the %prec directive. This
3097 is because to please POSIX, we do not require to end the rules with a
3098 semicolon. As a result,
3102 is ambiguous: either a rule which precedence is that of baz, or a rule,
3103 and then a declaration of the precedence of the token baz.
3105 * doc/bison.texinfo: Document %precedence.
3106 (Precedence Only): New.
3107 * src/assoc.h, src/assoc.c (precedence_assoc): New.

3111 * tests/calc.at: Use %precedence for NEG.
3112 * tests/conflicts.at (%precedence does not suffice)
3113 (%precedence suffices): New tests.

3174 (getopts): Support -d, --directive.
3176 2008-11-09 Akim Demaille <demaille@gostai.com>
3178 Use inline for small operations.

3180 (stack_symbol_type): Declare constructor and other operations as
3182 (yy_destroy_): Inline.
3184 2008-11-09 Akim Demaille <demaille@gostai.com>

3195 (yydestruct_): Rename as...
3196 (yy_destroy_): this.
3197 (b4_symbols_actions, YY_SYMBOL_PRINT): Adjust.
3198 (parser::parse): yyla is now of symbol_type.
3199 Use its type member instead of yytoken.
3201 2008-11-09 Akim Demaille <demaille@gostai.com>
3203 Rename data_type and stack_symbol_type.
3204 * data/lalr1.cc (data_type): Rename as...
3205 (stack_symbol_type): this.
3207 2008-11-09 Akim Demaille <demaille@gostai.com>
3209 Handle semantic value and location together.
3210 * data/lalr1.cc (b4_symbol_actions): Bounce $$ and @$ to
3211 yydata.value and yydata.location.
3212 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_)
3213 (YY_SYMBOL_PRINT): Now take semantic value and location as a

3233 Rely on the state stack to display reduction traces.
3234 To display rhs symbols before a reduction, we used information
3235 about the rule reduced, which required the tables yyrhs and
3236 yyprhs. Now use rely only on the state stack to get the same

3365 Add "%define assert" to variants.
3366 This is used to help the user catch cases where some value gets
3367 ovewritten by a new one. This should not happen, as this will
3370 Unfortunately this uncovered a bug in the C++ parser itself: the
3371 lookahead value was not destroyed between two calls to yylex. For
3372 instance if the previous lookahead was a std::string, and then an int,
3373 then the value of the std::string was correctly taken (i.e., the
3374 lookahead was now an empty string), but std::string structure itself
3377 This is now done in variant::build(other&) (which is used to take the
3378 value of the lookahead): other is not only stolen from its value, it
3379 is also destroyed. This incurs a new performance penalty of a few
3380 percent, and union becomes faster again.
3382 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.

3659 2008-11-03 Akim Demaille <demaille@gostai.com>
3661 Fuse the three stacks into a single one.
3663 In order to make it easy to perform benchmarks to ensure that
3664 there are no performance loss, lalr1.cc is forked into
3665 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
3668 Meanwhile, to make sure that lalr1-fusion.cc is correctly
3669 exercized by the test suite, the user must install a symbolic link
3670 from lalr1.cc to it.
3672 Instead of having three stacks (state, value, location), use a
3673 stack of triples. This considerably simplifies the code (and it
3674 will be easier not to require locations as currently does the C++
3675 parser), and also gives a 10% speedup according to
3676 etc/bench (probably mainly since memory allocation is done once
3677 instead of three times).
3679 Another motivation is to make it easier to destruct properly
3680 semantic values: now that they are bound to their state (hence
3681 symbol type) it will be easier to call the appropriate destructor.
3683 These changes should probably benefit the C parser too.
3685 * data/lalr1.cc: Copy as...
3686 * data/lalr1-fusion.cc: this new file.
3687 (b4_rhs_value, b4_rhs_location): New definitions overriding those
3689 (state_stack_type, semantic_stack_type, location_stack_type)
3690 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
3691 (data_type, stack_type, yystack_): New.
3692 (YYLLOC_DEFAULT, yypush_): Adjust.
3693 (yyerror_range): Now based on data_type, not location_type.
3695 2008-11-03 Akim Demaille <demaille@gostai.com>
3697 Push the state, value, and location at the same time.
3698 This is needed to prepare a forthcoming patch that fuses the three
3701 * data/lalr1.cc (parser::yypush_): New.
3702 (parser::yynewstate): Change the semantics: instead of arriving to
3703 this label when value and location have been pushed, but yystate
3704 is to be pushed on the state stack, now the three of them must
3705 have been pushed before. yystate still must be the new state.
3706 This allows to use yypush_ everywhere instead of individual
3707 handling of the stacks.
3709 2008-11-03 Akim Demaille <demaille@gostai.com>
3711 Prefer references to pointers.
3712 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
3713 definition to use references instead of pointers.

3723 Fix the output type.
3726 2008-11-03 Akim Demaille <demaille@gostai.com>
3728 Use variants to support objects as semantic values.
3729 This patch was inspired by work by Michiel De Wilde. But he used
3730 Boost variants which (i) requires Boost on the user side, (ii) is
3731 slow, and (iii) has useless overhead (the parser knows the type of
3732 the semantic value there is no reason to duplicate this
3733 information as Boost.Variants do).
3735 This implementation reserves a buffer large enough to store the
3736 largest objects. yy::variant implements this buffer. It was
3737 implemented with Quentin Hocquet.

3745 (b4_char_sizeof, yy::variant): New.
3746 (parser::parse): If variants are requested, define
3747 parser::union_type, parser::variant, change the definition of
3748 semantic_type, construct $$ before running the user action instead
3749 of performing a default $$ = $1.
3750 * examples/variant.yy: New.
3751 Based on an example by Michiel De Wilde.

3871 * src/files.c (compute_file_name_parts): When the user specifies
3872 --output but not --file-prefix, extract the directory prefix from the

4139 * NEWS (2.3b+): Rename to...
4140 (?.?): ... this because we're dropping the "+" version naming scheme,
4141 but, in general, we still can't be sure of our next release name.
4142 * bootstrap: Add a quick hack to remove from .gitignore the
4143 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile

4281 * tests/output.at ("Output file name: ("): Comment out test case for
4283 ("Output file name: )"): Likewise.
4285 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
4287 * GNUmakefile: Update git-version-gen invocation so make dist
4290 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
4292 Update to the current gnulib CVS repository, and fix trigraph handling
4294 * bootstrap: Update gnulib CVS repository URL.
4295 (symlink_to_dir): Encapsulate the code that guarantees the destination
4296 directory exists into...
4297 (check_dst_dir): ... this new function, and...
4298 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
4299 fail when copying files into lib/uniwidth/.
4300 * src/output.c (prepare_symbols): When writing yytname muscles, where
4301 symbol names will be encoded in C-string literals, tell quotearg to
4302 escape trigraphs. This used to be the default in gnulib.
4303 * tests/regression.at (Token definitions): Because of the change in
4304 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
4305 escapes trigraphs in symbol names. Thus, yytname no longer has
4306 trigraphs unnecessarily doubly escaped. Update test case output.
4307 Extend test case to be sure Bison's own error messages will no longer
4308 have trigraphs in symbol names unnecessarily escaped once.

5216 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
5218 In impure push mode, don't allow more than one yypstate to be allocated
5219 since multiple impure parsers would corrupt yynerrs.
5220 * data/push.c (yypstate_allocated): New static global variable
5222 (yypull_parse): If yypstate_new returns 0, don't report it as memory
5223 exhaustion if yypstate_allocated is 1, but still return 2.
5224 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is

5301 Get rid of broken %no-parser, -n, and --no-parser implementation and
5303 * TODO: Don't mention them.
5304 * doc/bison.1: Likewise.
5305 * doc/bison.texinfo (Decl Summary): Likewise.
5306 (Bison Options): Likewise.
5307 (Option Cross Key): Likewise.
5308 * src/getargs.c (no_parser_flag): Remove global variable.
5309 (usage): Don't print description of -n and --no-parser.
5310 (long_options): Remove --no-parser entry here.
5311 (getargs): Remove -n case in the switch here.
5312 * src/getargs.h (no_parser_flag): Remove extern.
5313 * tests/regression.at (Web2c Actions): Remove comment that mentions
5316 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
5318 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
5319 name user variables starting with `yy'. Just pass NULL instead of a
5320 dummy local &yylval to yypush_parse.
5321 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
5324 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
5326 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
5327 true since it's then always used regardless of whether yyoverflow is
5328 defined. Reported by Christian Burger at
5329 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
5330 * THANKS: Add Christian Burger.
5332 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
5333 node names: say "Decl Summary" not "Bison Declaration Summary".
5335 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
5337 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
5338 determine whether this function has already complained about an invalid
5339 value for a %define boolean variable, don't check whether Bison has
5340 ever examined the value. As written, the check was a tautology.
5341 Instead, record and check for this complaint using a separate muscle.
5343 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
5345 Fix push parsing memory leak reported by Brandon Lucia at
5346 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
5347 * THANKS: Add Brandon Lucia.
5348 * data/push.c (yypstate_delete): Free the stack if it was reallocated
5349 but the parse never completed and thus freed it.
5350 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
5351 * tests/testsuite.at: Include push.at.
5352 * test/push.at: New.
5353 (Push Parsing: Memory Leak for Early Deletion): New test case.
5355 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
5357 Improve handling of multiple S/R conflicts in the same state and of S/R
5358 conflicts involving multiple reductions.
5359 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
5360 set for a state here or Bison will abort if it is reassigned on a
5361 later conflicted reduction in the same state.
5362 Similarly, don't finalize and assign the solved conflicts report here
5363 or it will be lost if it is reassigned on a later conflicted reduction
5365 (set_conflicts): Instead, assign them both here after all S/R conflicts
5366 in the state have been fully examined.
5367 * src/print.c (shift_set): Rename to...
5368 (no_reduce_set): ... this.
5369 (print_reductions): Update for rename, and add %nonassoc error action
5370 tokens to no_reduce_set so that, when printing the first remaining
5371 reduction on an error action token, the reduction is enclosed in
5373 (print_results): Update for rename.
5374 * tests/conflicts.at (Solved conflicts report for multiple reductions
5375 in a state): New test case.
5376 (%nonassoc error actions for multiple reductions in a state): New test
5379 * src/main.c (main): Don't depend on C99 features.
5381 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
5383 * build-aux/.cvsignore: Add compile.
5384 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
5387 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
5389 * bootstrap (slurp): Create target directories that don't exist.
5390 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
5392 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
5394 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
5396 * closure.c (closure): Likewise.
5397 * state.h (reductions): Comment sorting of rules.
5398 (state): Comment sorting of items.
5400 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
5402 Fix C++ test cases after recent Gnulib changes. Discussed starting at
5403 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
5404 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
5405 definition in order to avoid Gnulib headers since we don't use config.h
5407 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
5408 rather than AT_DATA so that config.h is included.
5410 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
5412 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
5413 instead of fprintf. Guard these functions with #if YYDEBUG instead of
5414 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
5415 and so that YYFPRINTF is guaranteed to be defined here.
5417 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
5419 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
5421 (muscle_percent_define_check_values): ... this more helpful function.
5422 Again, it's not used yet, but it will be.
5423 * src/muscle_tab.h: Likewise.
5425 Improve some comments in parser table construction.
5426 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
5427 (generate_states): Don't mention ruleset, which is internal to closure.
5428 * src/closure.c (closure): Explain sorting of core and itemset, which
5429 is required for this function to behave correctly.
5430 * src/closure.h (closure): Mention sorting.
5432 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
5434 * src/lalr.c (state_lookahead_tokens_count): For code readability,
5435 move the check for disabled transitions to an aver since conflict
5436 resolution hasn't happened yet.
5438 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
5439 labels a state as inconsistent just because it has error transitions.
5440 The original form of this check appeared in revision 1.1 of lalr.c,
5441 which was committed on 1991-12-21. Now (at least), changing the
5442 consistency label on such a state appears to have no useful effect in
5443 any of the places it is examined, which I enumerate below. The key
5444 point to understanding each item in this enumeration is that a state
5445 with an error transition is labelled consistent in the first place only
5446 if it has no rules, so the check cannot matter for states that have
5447 rules. (1) Labelling a state as inconsistent will cause set_conflicts
5448 to try to identify its conflicts, and a state must have *rules* to have
5449 conflicts. (2) Labelling a state as inconsistent will affect how
5450 action_row sets the default *rule* for the state. (3) Labelling a
5451 state as inconsistent will cause build_relations to add lookback edges
5452 to *rules* in that state.
5453 * src/state.h (struct state): Word the comment for member consistent
5456 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
5458 Don't depend on C99 features.
5459 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
5460 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
5461 * src/reader.c (check_and_convert_grammar): Fix for-loop.
5462 * src/state.c (state_mark_reachable_states): Fix for-loop.
5463 (state_remove_unreachable_states): Fix for-loop.
5465 Don't widen struct state with member reachable just to temporarily
5466 record reachability. Instead, use a local bitset.
5467 * src/state.h (struct state): Remove member.
5468 * src/state.c (state_new): Don't initialize it.
5469 (state_mark_reachable_states): Rename to...
5470 (state_record_reachable_states): ... this, and use bitset.
5471 (state_remove_unreachable_states): Use bitset.
5473 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
5475 * src/Makefile.am (yacc): Quote target action commands properly so
5476 that the yacc script isn't corrupt. Reported by Hans Aberg at
5477 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
5479 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
5480 the case of pure parsers. Reported by Frans Englich at
5481 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
5482 * THANKS: Add Frans Englich.
5484 * NEWS (2.3a+): In the %code entry, reference section `Bison
5485 Declaration Summary' from the manual now since the %code summary has
5487 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
5488 in the rules section must be terminated by semicolons.
5490 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
5492 Extend the front-end API for %define variables to more completely
5493 mirror the back-end. This will be useful in the future.
5494 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
5495 Update comments to mention the new front-end counterparts of these
5497 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code

5503 (muscle_percent_define_flag_if): Use muscle_percent_define_ifdef and
5504 muscle_percent_define_get to mimic the b4_percent_define_flag_if
5505 implementation more closely.
5506 (muscle_percent_define_invalid_value): New function.
5507 * src/muscle_tab.h (muscle_percent_define_get,
5508 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
5511 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
5513 * NEWS (2.3a+): Mention yesterday's state-removal change.
5514 (2.3a): Remove the %language entry, which was added after 2.3a.
5515 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
5516 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
5517 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
5518 tests/existing.at: Update copyright date.
5520 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
5522 If conflict resolution makes states unreachable, remove those states,
5523 report rules that are then unused, and don't report conflicts in those
5525 * src/conflicts.c, src/conflicts.h (conflicts_update_state_numbers):
5526 New global function.
5527 * src/lalr.c, src/lalr.h (lalr_update_state_numbers): New global

5545 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
5546 (new_itemsets, save_reductions): Update for rename to nitemset.
5547 * src/closure.c (nritemset): Rename to...
5548 (nitemset): ... this since the "r" appears to meaningless and isn't
5549 used in the comments.
5550 (closure): Update for rename.
5551 * src/closure.h (nritemset): Update extern to...
5552 (nitemset): ... this.

5558 2007-04-04 Paul Eggert <eggert@cs.ucla.edu>
5560 * THANKS: Use ASCII for Sebastien Fricker's name. Bison source
5561 still sticks to ASCII. Sorry!

5615 file name genertion on Win98, WinXP, etc. These are |<>":?*\
5616 and concern testsuite case 46.
5617 * Makefile.am: djgpp/testsuite.sed added to EXTRA_DIST
5618 * djgpp/testsuite.sed: Inhibit the use of disallowed characters.
5619 * djgpp/config.bat: Inhibit the use of disallowed characters.
5621 2007-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5623 Miscellaneous %define and %code cleanup.
5624 * data/bison.m4 (b4_percent_define_flag_if): Correct comments on how
5625 values are interpreted.
5626 * doc/bison.texinfo (Decl Summary): Clean up and extend %define
5627 documentation a little more.
5628 * src/muscle_tab.c (MUSCLE_USER_NAME_CONVERT,
5629 muscle_percent_define_insert, muscle_percent_code_grow): New
5631 * src/muscle_tab.h (muscle_percent_define_insert,
5632 muscle_percent_code_grow): Prototype.
5633 * src/parse-gram.y (prologue_declaration): Use
5634 muscle_percent_define_insert and muscle_percent_code_grow when parsing
5635 %define and %code directives.
5637 Make it easy to share %define boolean variables between the front-end
5638 and back-end. Though not used yet, this will be useful in the future.
5639 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
5640 Bison uses of names rather than just skeleton uses of names.
5641 (b4_percent_define_get, b4_percent_define_ifdef): Rename
5642 b4_percent_define_skeleton_variables(VARIABLE) to
5643 b4_percent_define_bison_variables(VARIABLE).

5648 * src/muscle_tab.c, src/muscle_tab.h (muscle_percent_define_flag_if,
5649 muscle_percent_define_default): New functions mimicking
5650 b4_percent_define_flag_if and b4_percent_define_default.
5652 For %define variables, report locations for invalid values and
5654 * data/bison.m4 (b4_percent_define_flag_if): Read
5655 b4_percent_define_loc(VARIABLE) to report the location of an invalid
5657 (b4_percent_define_default): Save a special location in
5658 b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE
5659 must later be reported as invalid.
5660 * src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New
5662 (muscle_percent_define_insert): Record the location of VARIABLE in
5663 muscle percent_define_loc(VARIABLE), and use it to report the previous
5664 location for a redefinition.
5665 (muscle_percent_define_flag_if): Update like b4_percent_define_flag_if.
5666 (muscle_percent_define_default): Update like b4_percent_define_default.
5667 (muscle_grow_user_name_list): Rename to...

5675 2007-02-28 Joel E. Denny <jdenny@ces.clemson.edu>
5677 * src/print.c (lookahead_set, state_default_rule): Remove.
5678 (print_reductions): Replace state_default_rule invocation with
5679 equivalent use of yydefact, which was computed in token_actions in
5681 (print_results): Don't allocate lookahead_set.
5683 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
5685 * data/lalr1.java: Prefix all private members with yy.
5687 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
5689 Use YYFPRINTF instead of fprintf where appropriate. Reported by
5690 Sebastien Fricker at
5691 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
5692 * THANKS: Add Sebastien Fricker.
5693 * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
5694 * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must
5695 accept a variable number of arguments.
5697 2007-02-19 Joel E. Denny <jdenny@ces.clemson.edu>
5699 * bootstrap: Remove occurrences of .#bootmp from lib/Makefile.
5701 2007-02-13 Juan Manuel Guerrero <juan.guerrero@gmx.de>

5707 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
5709 Undo my 2007-02-07 change, switching back to the c-strcase module
5710 introduced in the 2007-02-03 change. Bruno Haible reported that
5711 the 2007-02-07 change would be dangerous in Turkish if we add a
5712 language whose name contains "i", since "i" is not lowercase "I"
5714 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
5715 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
5716 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
5717 * m4/.cvsignore: Remove strcase.m4.
5718 * src/getargs.c: Revert 2007-02-07 change, as follows.
5719 Include c-strcase.h.
5720 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
5722 2007-02-11 Bruno Haible <bruno@clisp.org>
5724 Enable the Java related testsuite tests when the only Java compiler
5725 found is a gcj < 4.3. Discussed at
5726 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
5727 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
5729 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
5731 * data/Makefile.am: Update copyright date.
5732 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
5733 yypstate_new returns NULL.
5734 (yypstate_new): Return NULL if malloc does.
5735 * src/reader.c (packgram): Move translation of rule actions from the
5736 beginning of packgram to...
5737 (check_and_convert_grammar): ... here right before packgram is invoked
5738 so it's easier to write more complete comments, and remove redundant
5741 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
5743 As in semantic actions, make @$ in %initial-action, %destructor, and
5744 %printer imply %locations.
5745 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
5747 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
5748 (@$ in %initial-action implies %locations,
5749 @$ in %destructor implies %locations,
5750 @$ in %printer implies %locations): ... these new test cases.
5752 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
5754 Undo most of the 2007-02-03 change, switching to the strcase module
5755 now that gnulib strcase has been fixed.
5756 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
5757 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
5758 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
5759 * m4/.cvsignore: Add strcase.m4.
5760 * src/getargs.c: Revert 2007-02-03 change, as follows.
5761 Don't include c-strcase.h.
5762 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
5763 strcasecmp has "unspecified behavior" outside the POSIX locale,
5764 but it works fine in practice if at least one argument is ASCII,
5765 as is the case in Bison.
5767 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
5769 * tests/java.at: Skip tests if only one of javac/java is present.
5770 Reported by Joel E. Denny.
5771 * tests/atlocal.in: Adjust copyright years.
5773 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
5775 * data/lalr1.java (Stack): Work around old verifiers that disallow
5776 access to the private fields of an inner class, from the outer class.
5777 We can make Stack's fields public because user code doesn't have access
5778 to the instance of Stack used by parse(). Reported by Paul Eggert.
5780 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
5782 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
5783 the right spot for these files?
5784 * bootstrap.conf (gnulib_modules): Add c-strcase.
5785 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
5787 * src/getargs.c: Include c-strcase.h.
5788 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
5789 to avoid unspecified behavior.
5791 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
5793 * doc/bison.texinfo (Decl Summary): Correct typo.
5795 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
5797 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
5798 Complain if the value does not match empty, "true" or "false".
5799 * data/c++.m4: Adjust default definitions of %define variables.
5800 * data/java.m4: Adjust default definitions of %define variables.
5801 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
5803 * tests/input.at (Boolean %define variables): Test new behavior.
5805 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
5807 * NEWS: Mention java.
5808 * TODO: Remove things that are done.
5809 * bootstrap.conf: Add javacomp-script and javaexec-script.
5810 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
5812 * data/Makefile.am: Add new files.
5813 * data/java-skel.m4: New.
5814 * data/java.m4: New.
5815 * data/lalr1.java: New.
5817 * doc/bison.texinfo: Put "A Complete C++ Example" under
5818 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
5819 under Other Languages.
5821 * src/getargs.c (valid_languages): Add Java.
5822 * src/getargs.h (struct bison_language): Update size of string fields.
5824 * tests/Makefile.am: Add java.at.
5825 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
5826 * tests/java.at: New.
5827 * tests/testsuite.at: Include it.
5829 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
5832 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
5833 at_directive_argv arguments so these no longer have to be global
5834 variables. Also, update the implementation for the following changes.
5835 (fail_for_at_directive_too_many_args,
5836 fail_for_at_directive_too_few_args): Add at_directive_name argument.
5837 (at_directive_name): Remove as at_directive_argv[0] will be used for
5839 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
5840 for the directive name.
5841 (at_directive_argc, at_directive_argv): Make these local within
5842 skel_lex instead of global.
5843 (INITIAL): Update directive start action for above changes.
5844 (SC_AT_DIRECTIVE_ARG): Rename to...
5845 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
5846 (SC_AT_DIRECTIVE_SKIP_WS): Update.
5847 (scan_skel): Move yylex_destroy to...
5848 (skel_scanner_free): ... here.
5849 * tests/skeletons.at (installed skeleton file name): Rename to...
5850 (installed skeleton file names): ... this.
5852 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
5854 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
5855 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
5856 Summary" not "Directives".
5857 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
5858 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
5859 since the former is now the more complete one.
5860 (Prologue Alternatives): Likewise and do the same for %defines.
5861 (Table of Symbols): Add summary of %code, add summary of %define, and
5862 move full %code documentation to...
5863 (Decl Summary): ... here for consistency with other entries in these
5865 Move %define entry in order to keep this list alphabetized.
5866 Reword %define entry a little to put less emphasis on the skeleton
5867 concept, which most users shouldn't have to think about.
5869 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
5871 Adjust to recent gnulib changes.
5872 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
5873 Add string.h, string_.h, unistd_.h, wchar_.h.
5874 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
5875 * src/system.h: Don't include <stpcpy.h>; this is now done by
5878 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
5880 Simplify implementation of unqualified %code, implement macros for
5881 uniform treatment of boolean %define flags. Document %define.
5882 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
5883 b4_percent_code_ifdef): New.
5884 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
5885 * data/c++.m4: Define default value for global_tokens_and_yystype.
5886 * data/glr.cc: Likewise.
5887 * data/location.cc: Use b4_percent_define_flag_if.
5889 * doc/bison.texinfo (Decl Summary): Document %define.
5891 * src/parse-gram.y (Unqualified %code): Change muscle name to
5893 (content.opt): Default to empty.
5895 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
5897 Implement support for relative and absolute skeleton file names.
5898 Discussed starting at
5899 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
5900 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
5901 (Bison Options): Document in --skeleton entry.
5902 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
5903 full_skeleton can't necessarily hold all of pkgdatadir.
5904 If the specified skeleton file name contains a `/', don't prepend
5906 * src/parse-gram.y (prologue_declaration): If the specified skeleton
5907 file name contains a `/', prepend the grammar file directory.
5908 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
5909 * skeletons.at: New file.
5910 (relative skeleton file names): New test case.
5911 (installed skeleton file names): New test case.
5912 * tests/testsuite.at: Include skeletons.at.
5914 * bootstrap: Update copyright to 2007.
5916 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
5918 * bootstrap: Remove occurrences of .#bootmp from the files.
5920 2007-01-17 Akim Demaille <akim@epita.fr>
5922 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
5924 Use per-type %printer.
5926 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
5928 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

5936 2007-01-16 Akim Demaille <akim@epita.fr>
5938 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
5940 (Calc++ Scanner): Exit with failure if we can't open the input
5942 Accept "-" standing for stdin.
5943 (Calc++ Top Level): Print the result only if the parsing was
5946 2007-01-16 Akim Demaille <akim@epita.fr>
5948 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
5950 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
5951 and Joel E. Denny <jdenny@ces.clemson.edu>
5953 Clean up %define and %code implementation in M4 some. Most
5954 importantly, rename all related macros to be in the b4_percent_define
5955 and b4_percent_code namespaces. Also, complete support for `.' in
5956 %define variable names and %code qualifiers.
5957 * data/bison.m4 (b4_check_user_names): Check for special
5958 "SKELETON-NAMESPACE(name)" macros instead of using two nested
5960 (b4_get_percent_define, b4_get_percent_code): Rename to...
5961 (b4_percent_define_get, b4_percent_code_get): ... these.
5962 Extend documentation with examples.
5963 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
5964 b4_percent_define_skeleton_variables and
5965 b4_percent_code_skeleton_qualifiers.
5966 Expect any value for the %define variable `foo' to be stored in the
5967 macro named `b4_percent_define(foo)'; expect any %code blocks for the
5968 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
5969 expect any unqualified %code blocks to be stored in a macro named
5970 `b4_percent_code_unqualified'.
5971 Use m4_indir so that %define variable names and %code qualifiers can
5972 contain `.', which is allowed by the grammar parser.
5973 (b4_percent_define_default): New macro to set a default value for a
5975 (m4_wrap): Update wrapped code, and fix some underquoting.
5976 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
5977 Expect grammar uses of %define variables and %code qualifiers to be
5978 defined in b4_percent_define_user_variables and
5979 b4_percent_code_user_qualifiers.
5980 * data/c++.m4: Use b4_percent_define_default rather than
5981 m4_define_default. Fix some underquoting. Skeleton usage of %define
5982 variable define_location_comparison now implies skeleton usage of
5983 %define variable filename_type.
5984 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
5985 data/push.c, data/yacc.c: Update macro names.
5986 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
5989 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
5991 DJGPP specific issues.
5993 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
5994 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
5996 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5998 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
5999 run parsers in all tests so that Valgrind is invoked during
6000 maintainer-check-valgrind.
6001 (Duplicate representation of merged trees): Free all semantic values.
6002 (Duplicated user destructor for lookahead): Likewise.
6004 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
6006 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
6007 command-line prefix.
6008 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
6009 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
6010 miss Valgrind messages.
6011 (Exploding the Stack Size with Malloc): Likewise.
6013 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
6015 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
6016 locals. Reported by Juan Manuel Guerrero at
6017 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
6018 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
6019 Fix some indentation also.
6020 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
6021 explaining this issue.
6023 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
6024 and Joel E. Denny <jdenny@ces.clemson.edu>
6026 Simplify union and prologue handling, and escape union and lex/parse
6027 params with digraphs.
6028 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
6029 values to the empty string since these are no longer guaranteed
6030 initialized by the front-end.
6031 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
6032 braces around b4_user_stype since this is no longer done by the
6034 * src/files.c, src/files.h (pre_prologue_obstack,
6035 post_prologue_obstack): Remove.
6036 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
6037 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
6038 with digraphs. This fixes lex params and parse params.
6039 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
6040 * src/output.c (prepare): Remove muscle insertion of the prologues.
6041 (output): Remove freeing of pre_prologue_obstack and
6042 post_prologue_obstack.
6043 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
6044 than prologue_augment for prologue parsing so you don't need prologue
6046 (grammar_declaration): For %union RHS, use `braceless' instead of
6047 "{...}" so that braces are already stripped and code is escaped with
6049 * src/reader.c (prologue_augment): Remove.
6050 (reader): Remove initialization of pre_prologue_obstack and
6051 post_prologue_obstack.
6052 * src/reader.h (prologue_augment): Remove.
6054 * data/c.m4: Remove stray parenthesis.
6056 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
6058 Remove quotes from variables names in %define directives and from
6059 qualifiers in %code directives, and restrict the characters that are
6060 allowed in them to M4-friendly ones. For %define, continue to support
6061 the quoted form as a deprecated feature. Discussed starting at
6062 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
6063 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
6065 * doc/bison.texinfo (Prologue Alternatives): Update.
6066 (Decl Summary): In %defines entry, update mention of `%code requires'
6067 and `%code provides'.
6068 (C++ Location Values): Update %define uses.
6069 (Calc++ Parser Interface): Likewise.
6070 (Calc++ Parser): Likewise, and update `%code requires' uses.
6071 (Table of Symbols): Update %code documentation.
6072 * src/parse-gram.y (prologue_declaration): For %define variables, use
6073 `variable' instead of `STRING'.
6074 (grammar_declaration): For %code qualifiers, use `ID' instead of
6076 (variable): New nonterminal that takes an `ID' or a `STRING'.
6077 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
6079 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
6080 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
6081 (%define errors): Update %define uses.
6083 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
6085 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
6086 instead of muscle_insert for %define values so that M4-special
6087 characters are replaced with digraphs.
6088 * tests/input.at (%define errors): Extend to check weird values.
6090 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
6092 Instead of having skeletons declare all valid %define variables and
6093 %code qualifiers, provide macros that retrieve the associated values
6094 and build these lists automatically. Thus Bison will now warn when a
6095 variable or qualifier is not used by the skeleton in the current
6096 invocation regardless of whether it might sometimes be used by that
6097 skeleton in other invocations. Also, move all %define value macros to
6098 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
6099 form, which is replaced by %code.
6100 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
6101 (b4_check_user_names): ... this, and change the series of valid name
6102 arguments to a single list argument for names used in the skeleton
6103 similar to the existing list argument for names used in the grammar.
6104 Warn instead of complaining.
6105 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
6106 values and %code code, to format %code code properly, and to build
6107 lists of all %define variables and %code qualifiers used in the
6108 skeleton: b4_skeleton_percent_define_variables and
6109 b4_skeleton_percent_code_qualifiers.
6110 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
6112 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
6113 the skeleton names lists can finish building first. In place of
6114 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
6115 expect the lists b4_user_percent_define_variables and
6116 b4_user_percent_code_qualifiers.
6117 * data/c++.m4: Where setting default values for b4_parser_class_name,
6118 b4_location_type, b4_filename_type, b4_namespace, and
6119 b4_define_location_comparison, update their names to the
6120 b4_percent_define_ namespace.
6121 * data/glr.c: Don't use b4_check_percent_define_variables and
6122 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
6123 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
6124 (b4_parser_class_name, b4_namespace): Define these using
6125 b4_get_percent_define for parser_class_name and namespace.
6126 * data/location.cc: Use b4_get_percent_define.
6127 * data/push.c: Don't use b4_check_percent_define_variables and
6128 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
6129 * data/yacc.c: Likewise, and don't call m4_exit in
6130 b4_use_push_for_pull_if or m4_wrap code will never execute.
6131 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
6133 (muscle_grow_user_name_list): ... this for consistency with the
6134 terminology used in bison.m4.
6135 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
6136 %define variable names, and rename muscle used_percent_define_variables
6137 to user_percent_define_variables.
6138 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
6139 user_percent_code_qualifiers.
6141 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
6142 {CODE} form is no longer accepted.
6143 * tests/input.at (Reject bad %code qualifiers): Rename to...
6144 (Reject unused %code qualifiers): ... this, and update test output.
6145 (%define error): Update test output.
6147 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
6149 Check for unrecognized %define variables similar to checking for
6150 unrecognized %code qualifiers. Check for redefined %define variables.
6151 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
6153 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
6154 (b4_check_percent_define_variables): New, also wraps it.
6155 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
6156 variables using b4_check_percent_define_variables.
6157 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
6158 all those exercised in the test suite and all those listed in the
6159 `Default values' section of c++.m4. Are there others?
6160 * data/push.c, data/yacc.c: Declare no valid %define variables.
6161 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
6162 similar to muscle_find, but it works even when the muscle stores a
6164 (muscle_grow_used_name_list): New function for constructing the used
6165 name list muscles that b4_check_for_unrecognized_names requires.
6166 * src/parse-gram.y (prologue_declaration): Warn if a variable is
6167 %define'd more than once. Define the b4_used_percent_define_variables
6168 muscle with muscle_grow_used_name_list.
6169 (grammar_declaration): Abbreviate %code code with
6170 muscle_grow_used_name_list.
6171 * tests/input.at (%define errors): New.
6173 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6175 Provide warn_at, complain_at, and fatal_at function callbacks to the
6176 skeletons, and use this for %code qualifier complaints.
6177 * data/bison.m4 (b4_error_at): New, invoked by...
6178 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
6179 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
6180 @fatal_at(...@) directives.
6181 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
6182 qualifiers in b4_used_percent_code_qualifiers and to use
6184 * src/location.c, src/location.h (boundary_set_from_string): New global
6186 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
6188 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
6189 to b4_used_percent_code_qualifiers.
6190 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
6192 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
6193 (lineno): Rename to...
6194 (out_lineno): ... this so I don't misunderstand it again.
6195 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
6196 here; these newlines are in the input but not the output file.
6197 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
6198 (at_directive_perform): ... this new static function, and add handling
6199 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
6201 * tests/input.at (Reject bad %code qualifiers): Update test output with
6202 locations and extend.
6204 * tests/output.at (Output file name: [, Output file name: ]): Remove
6205 bogus comment about these tests failing.
6207 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6209 Clean up b4_check_percent_code_qualifiers a little.
6210 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
6211 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
6212 documentation and add examples.
6213 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
6216 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
6218 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
6219 unreliable -- especially when they're hidden inside another macro.
6220 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
6221 data/c.m4: Remove m4_divert(-1).
6222 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
6223 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
6224 m4_divert_push(0) and m4_divert_pop(0).
6225 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
6226 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
6227 pushed and popped by m4sugar, should be first on the stack.
6229 Provide warn, complain, and fatal function callbacks to the skeletons.
6230 This provides more flexibility than m4_fatal, improves the error
6231 message format, and captures messages for translation. Discussed
6233 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
6234 * data/bison.m4 (b4_error): New, invoked by...
6235 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
6236 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
6237 directives. Because these M4 macros might be called when the current
6238 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
6239 the previous removal of uses of m4_divert, which caused trouble.
6240 (b4_check_percent_code_qualifiers): Use b4_complain instead of
6241 m4_fatal to report unrecognized %code qualifiers.
6242 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
6243 push parser requests.
6244 * data/glr.c: Use b4_complain instead of m4_fatal to report
6245 non-deterministic push parser requests.
6246 Update @output usage to @output(...@) form.
6247 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
6248 report missing %defines. Update @output usage to @output(...@) form.
6249 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
6251 * src/main.c (main): Invoke skel_scanner_free.
6252 * src/scan-skel.h (skel_scanner_free): Prototype new function.
6253 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
6254 obstack_for_string from flex-scanner.h.
6255 (YY_DECL): Use to declare skel_lex static.
6256 (decode_at_digraphs): Remove; now handled in the new
6257 SC_AT_DIRECTIVE_ARG start condition.
6258 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
6260 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
6261 at_directive_argv): New static globals.
6262 (INITIAL): Use fail_for_invalid_at.
6263 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
6264 recognize the start of a generalized `@directive(...@)' form and
6266 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
6267 directive args (using the new obstack_for_string), to decode the
6268 contained @ diagraphs, and to perform the directive. It recognizes
6269 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
6271 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
6272 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
6274 (scan_skel): Initialize obstack_for_string on the first call.
6275 (skel_scanner_free): New function to free obstack_for_string.
6276 * tests/input.at (Reject bad %code qualifiers): Update test output.
6278 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
6280 Consolidate the 4 prologue alternative directives (%code, %requires,
6281 %provides, and %code-top) into a single %code directive with an
6282 optional qualifier field. Discussed at
6283 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
6284 * NEWS (2.3a+): Rewrite the existing entry for the prologue
6286 * doc/bison.texinfo (Prologue Alternatives): Update.
6287 (Decl Summary): Update to %code "requires" and %code "provides".
6288 (Calc++ Parser): Update to %code "requires".
6289 (Table of Symbols): Remove entries for %requires, %provides, and
6290 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
6291 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
6292 are replaced by b4_percent_code_provides and b4_percent_code_requires,
6293 which are skeleton-specific.
6294 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
6295 declare what %code qualifiers it supports and to complain if any other
6296 qualifiers were used in the grammar.
6297 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
6298 and b4_user_code([b4_percent_code_provides]) in place of
6299 b4_user_requires and b4_user_provides.
6300 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
6301 Add b4_user_code([b4_percent_code_top]) and
6302 b4_user_code([b4_percent_code]).
6303 Invoke b4_check_percent_code_qualifiers.
6304 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
6305 PERCENT_REQUIRES): Remove.
6306 (grammar_declaration): Remove RHS's for %code-top, %provides, and
6307 %requires. Rewrite the %code RHS as the unqualified form defining the
6308 muscle b4_percent_code. Add another RHS for the qualified %code form,
6309 which defines muscles of the form b4_percent_code_QUALIFIER and the
6310 b4_used_percent_code_qualifiers muscle.
6311 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
6312 PERCENT_REQUIRES): Remove.
6313 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
6314 %code "requires" and %code "provides".
6315 * tests/input.at (Reject bad %code qualifiers): New.
6317 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
6319 Use the new code_props interface for destructors and printers.
6320 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
6321 printer_location members, and change the type of the destructor and
6322 printer members to code_props.
6323 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
6324 symbol_printer_get, semantic_type_destructor_set,
6325 semantic_type_printer_set, default_tagged_destructor_set,
6326 default_tagless_destructor_set, default_tagged_printer_set,
6327 default_tagless_printer_set): Use code_props in arguments and return
6328 types in place of char const * and location.
6329 (symbol_destructor_location_get, symbol_printer_location_get): Remove
6330 since the locations are now contained in the return of
6331 symbol_destructor_get and symbol_printer_get.
6332 * src/output.c (symbol_destructors_output, symbol_printers_output):
6334 (symbol_code_props_output): ... this to eliminate duplicate code.
6335 (output_skeleton): Update to use symbol_code_props_output.
6336 * src/reader.c (symbol_should_be_used): Update use of
6337 symbol_destructor_get.
6338 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
6339 Update uses of the various _destructor_set and _printer_set functions.
6340 * src/symtab.c: (default_tagged_destructor_location,
6341 default_tagless_destructor_location, default_tagged_printer_location,
6342 default_tagless_printer_location): Remove since we...
6343 (default_tagged_destructor, default_tagless_destructor,
6344 default_tagged_printer, default_tagless_printer): ... change the type
6345 of these to code_props.
6346 (symbol_new, semantic_type_new, symbol_destructor_set,
6347 semantic_type_destructor_set, symbol_destructor_get,
6348 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
6349 symbol_check_alias_consistency, default_tagged_destructor_set,
6350 default_tagless_destructor_set, default_tagged_printer_set,
6351 default_tagless_printer_set): Update.
6352 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
6353 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
6355 (symbol_print): Use SYMBOL_CODE_PRINT.
6357 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
6359 Use the new code_props interface for rule actions.
6360 * src/symlist.h (symbol_list): Replace action, action_location, and
6361 used members with a code_props action_props member.
6362 * src/reader.c (symbol_should_be_used, grammar_rule_check,
6363 grammar_midrule_action, grammar_current_rule_merge_set,
6364 grammar_current_rule_symbol_append, packgram): Update.
6365 * src/scan-code.h (translate_rule_action): Remove, no longer used.
6366 * src/scan-code.l (handle_action_dollar): Update.
6367 (translate_rule_action): Remove, no longer used.
6368 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
6370 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
6372 Use the new code_props interface in parse-gram.y.
6373 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
6374 Update all uses of translate_* functions to use the new code_props
6375 interface and to use gram_scanner_last_string_free and
6376 code_scanner_last_string_free where possible.
6377 (grammar_declaration): symbol_list_destructor_set and
6378 symbol_list_printer_set now perform the translation, so don't do it
6379 here. Use gram_scanner_last_string_free where possible.
6380 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
6381 translate_code): Remove, no longer used.
6382 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
6383 symbol_list_printer_set): Perform code translation here rather than
6384 depending on the caller to do so.
6386 * src/symlist.h (struct symbol_list): Correct some documentation typos.
6387 * src/scan-gram.h (gram_last_string): Remove declaration.
6388 * src/scan-gram.l (last_string): Declare it static.
6390 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
6392 Encapsulate code properties and related functionality for the various
6393 destructors, printers, and actions into a code_props structure and
6394 interface. This patch merely implements code_props in scan-code.h and
6395 scan-code.l. Future patches will rewrite other modules to use it.
6396 Discussed starting at
6397 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
6398 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
6399 consistently initialize const structs that have an empty location
6401 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
6402 to ensure consistency.
6403 * src/scan-code.h (code_props): New structure.
6404 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
6405 function, macro, and const global variable for initializing a
6406 code_props with no code.
6407 (code_props_plain_init, code_props_symbol_action_init,
6408 code_props_rule_action_init, code_props_translate_code): The rest of
6409 the new code_props functional interface. Among other things, the init
6410 functions set the code_props kind field so that
6411 code_props_translate_code will know whether to behave like
6412 translate_symbol_action, translate_rule_action, or translate_code.
6413 These old translate functions must remain until all other modules are
6414 updated to use the new code_props interface.
6415 (code_scanner_last_string_free): New function similar to
6416 gram_scanner_last_string_free.
6417 (code_scanner_free): Add documentation.
6418 * src/scan-code.l: Implement the new interface.
6419 (code_lex): Make it static, add a code_props* argument, and remove the
6421 (last_string): New static global similar to the one in scan-gram.l.
6422 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
6424 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
6425 code_props since Bison may one day use this information for destructors
6427 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
6428 (handle_action_dollar): Use symbol_list_n_get and set used flag
6429 directly since symbol_list_n_used_set is removed.
6430 (translate_action): Add a code_props* argument and remove the rule,
6431 action, and location arguments. Pass the code_props* on to code_lex.
6432 (translate_rule_action, translate_symbol_action, translate_code):
6433 Rewrite as wrappers around the new code_props interface.
6434 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
6435 it would eventually need to break the encapsulation of code_props.
6437 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
6439 * etc/.cvsignore: New.
6441 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
6443 Add maintainer-push-check to run maintainer-check using push parsing in
6444 place of pull parsing where available.
6445 * Makefile.am (maintainer-push-check): New.
6446 * data/bison.m4 (b4_use_push_for_pull_if): New.
6447 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
6448 appropriately based on their existing values.
6449 (yypush_parse): Don't print push-parser-specific diagnostics if push
6450 parsing is being used in place of pull parsing.
6451 * data/yacc.c: If push parsing should replace pull parsing, redirect to
6453 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
6454 variable, and insert b4_use_push_for_pull_flag into muscles.
6455 * tests/Makefile.am (maintainer-push-check): New.
6457 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
6459 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
6460 (whether successful or failed) so that yypush_parse can be invoked
6461 again to start a new parse using the same yypstate.
6462 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
6463 check multiple yypull_parse invocations on the same yypstate. For pull
6464 mode, extend to check multiple yyparse invocations.
6465 (Exploding the Stack Size with Alloca): Extend to try with
6467 (Exploding the Stack Size with Malloc): Likewise.
6469 * tests/calc.at (Simple LALR Calculator): Don't specify
6470 %skeleton "push.c" since %push-pull-parser implies that now.
6471 * tests/headers.at (export YYLTYPE): Don't check for the push
6472 declarations. Otherwise, this test case can't be used to see if push
6473 mode can truly emulate pull mode.
6474 * tests/input.at (Torturing the Scanner): Likewise.
6475 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
6476 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
6477 AT_YACC_IF, which now includes the case of push mode since %skeleton
6478 need not be used for push mode. This will be more intuitive once
6479 push.c is renamed to yacc.c.
6481 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
6483 For push mode, convert yyparse from a macro to a function, invoke yylex
6484 instead of passing a yylexp argument to yypull_parse, and don't
6485 generate yypull_parse or yyparse unless %push-pull-parser is declared.
6486 Discussed starting at
6487 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
6488 * data/bison.m4 (b4_pull_if): New.
6489 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
6490 * data/push.c: Improve M4 quoting a little.
6491 (b4_generate_macro_args, b4_parenthesize): Remove.
6492 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
6493 any time a pull parser is requested.
6494 Don't #define this as a wrapper around yypull_parse. Instead, when
6495 both push and pull are requested, make it a function that does that
6497 (yypull_parse): If there's a b4_prefix, #define this to
6498 b4_prefix[pull_parse] when both push and pull are requested.
6499 Don't define this as a function unless both push and pull are
6501 Remove the yylexp argument and hard-code yylex invocation instead.
6502 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
6504 * src/getargs.c (pull_parser): New global initialized to true.
6505 * getargs.h (pull_parser): extern it.
6506 * src/output.c (prepare): Insert pull_flag muscle.
6507 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
6508 (prologue_declaration): Set both push_parser and pull_parser = true for
6509 %push-pull-parser. Set push_parser = true and pull_parser = false for
6511 * src/scan-gram.l: Don't accept %push_parser as an alternative to
6512 %push-parser since there's no backward-compatibility concern here.
6513 Scan %push-pull-parser.
6514 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
6515 instead of %push-parser.
6516 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
6517 prototype it in the module that calls yyparse.
6518 * tests/input.at (Torturing the Scanner): Likewise.
6519 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
6521 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
6523 Update etc/bench.pl. Optimize push mode a little (the yyn change
6524 deserves most of the credit).
6525 * Makefile.am (SUBDIRS): Add etc subdirectory.
6526 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
6527 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
6528 yytoken, yyval, and yyloc declarations to...
6529 (yyparse or yypush_parse): ... here to improve performance. For
6530 yypush_parse invocations after the first, be sure to assign yyn its old
6532 (yypstate_new): Don't bother initializing the yyresult field since the
6533 initial value isn't used.
6534 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
6535 remove the #define that, in push mode, set it to yyps->NAME.
6536 * etc/Makefile.am: New.
6537 * etc/bench.pl: Remove and build it instead from...
6538 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
6539 "tests/bison" from the build directory by default rather than just
6540 invoking "bison" from $PATH.
6541 (calc_grammar): Update push parser code: don't declare yylval globally,
6542 don't define yyparse_wrapper, and don't #define yyparse.
6543 (bench_grammar): Update to check all working combinations of yacc.c,
6544 push.c, impure, pure, pull, and push.
6546 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
6548 For push mode, add pull wrappers around yypush_parse.
6549 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
6550 (yypull_parse): New function wrapping yypush_parse.
6551 (yyparse): New #define wrapping yypull_parse.
6552 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
6554 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
6555 prototype yylex in the module that calls yyparse, and don't prototype
6556 yyparse there. Otherwise, the yyparse expansion won't compile.
6557 * tests/input.at (Torturing the Scanner): Likewise.
6559 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
6561 Enable push parsers to operate in impure mode. Thus, %push-parser no
6562 longer implies %pure-parser. The point of this change is to move
6563 towards being able to test the push parser code by running the entire
6564 test suite as if %push-parser had been declared.
6565 * data/push.c (yypush_parse): For impure mode, remove the
6566 yypushed_char, yypushed_val, and yypushed_loc arguments.
6567 Instead, declare these as local variables initialized to the global
6568 yychar, yylval, and yylloc.
6569 For the first yypush_parse invocation only, restore the initial values
6570 of these global variables when it's time to read a token since they
6571 have been overwritten.
6572 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
6574 * tests/calc.at (Simple LALR(1) Calculator): Always declare
6575 %pure-parser along with %push-parser since this test case was designed
6576 for pure push parsers.
6577 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
6578 (AT_YACC_OR_PUSH_IF): New.
6579 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
6580 add a note that it's still wrong for some cases (as it has been for a
6582 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
6583 %push-parser no longer implies %pure-parser.
6585 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
6587 Remove some unnecessary differences between the pull parser code and
6588 the push parser code. This patch enables yynerrs in push mode.
6589 * data/push.c: Reformat M4 a little.
6590 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
6591 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
6592 because push mode is on. Instead, if pure mode is on, move yynerrs
6594 (b4_declare_parser_state_variables): ... here.
6595 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
6596 to yyps->NAME so it can be used in yypush_parse.
6597 (yypush_parse): Don't omit uses of yynerrs in push mode.
6599 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
6601 Fix bug such that the first pushed token's value and location are
6602 sometimes overwritten (sometimes by %initial-action) before being used.
6603 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
6604 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
6605 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
6606 more closely mimic the pull parser logic.
6607 Don't copy the pushed token to yychar, yylval, and yylloc until it's
6608 time to read a token, which is after any initialization of yylval and
6610 (gottoken): Rename label to...
6611 (yyread_pushed_token): ... for clarity and to avoid infringing on the
6614 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
6616 Rearrange initialization of the parser state variables so that the
6617 skeleton doesn't have to have a copy for pull mode and another for push
6618 mode. This patch also fixes at least a bug such that yylloc was not
6619 initialized (with b4_location_initial_line and
6620 b4_location_initial_column) upon calling yypush_parse. However, that
6621 initialization now overwrites the first token's location;
6622 %initial-action assigning @$ already did the same thing, and both bugs
6623 will be fixed in a later patch.
6624 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
6625 (b4_declare_parser_state_variables): Remove initialization of yytoken,
6626 yyss, yyvs, yyls, and yystacksize.
6627 (yypstate_new): Remove initialization of some yypstate fields: yystate,
6628 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
6630 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
6631 yyps->NAME so it can be used in yypush_parse.
6632 (yyparse or yypush_parse): For yypush_parse, don't print the
6633 "Starting parse" diagnostic for invocations after the first.
6634 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
6635 yypush_parse, only do it for the first invocation.
6636 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
6637 initialization to occur in yypush_parse but only on the first
6640 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
6642 * data/push.c: Add CPP guards around push parser declarations in both
6643 the header and the code file.
6644 In the code file, move the push parser declarations to the same place
6645 they appear in the header file.
6646 Clean up the M4 some, especially the inconsistent underquoting in
6647 some b4_c_function_def and b4_c_function_decl uses.
6649 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
6651 Encapsulate the push parser state variables into an M4 macro so the
6652 push skeleton doesn't have to list them again for pull mode's yyparse.
6653 For push mode, remove yypush_parse's local equivalents of these
6654 variables to eliminate unnecessary copying between the two sets at
6655 run-time. This patch also fixes at least a bug related to multiple
6656 %initial-action invocations in push mode.
6657 * data/push.c (b4_declare_parser_variables): Rename to...
6658 (b4_declare_scanner_communication_variables): ... this for clarity and
6660 (b4_declare_yyparse_variables): Remove and move its contents to the one
6661 spot where it was invoked.
6662 (b4_declare_parser_state_variables): New macro containing the parser
6663 state variables required by push mode.
6664 (struct yypstate): Replace all fields but yynew with
6665 b4_declare_parser_state_variables.
6666 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
6667 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
6668 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
6669 (yyparse or yypush_parse): For yyparse in pull mode, replace local
6670 parser state variable declarations with
6671 b4_declare_parser_state_variables.
6672 Don't initialize parser state variables when calling yypush_parse since
6673 yypstate_new already does that.
6674 Invoke the user's initial action only upon the first yypush_parse
6676 Remove all code that copies between the local parser state variables
6679 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
6681 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
6682 prevent a name collision in a future patch where these names will
6683 sometimes be #define'd.
6684 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
6685 since it no longer has the same name as the existing argument.
6686 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
6688 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
6689 and Joel E. Denny <jdenny@ces.clemson.edu>
6691 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
6692 that the argument is case-insensitive, and there's no `=' here.
6693 For the %skeleton entry, mention that %language is better.
6694 (Bison Options): Likewise for --language and --skeleton. Move the
6695 --skeleton entry so that the `Tuning the parser' section is sorted
6696 alphabetically on long options.
6697 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
6698 %language directive in detail here; cross-reference the %language
6699 documentation instead.
6700 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
6701 `%require "2.3b"' so that the example is always up-to-date.
6702 (Table of Symbols): Add entries for %language and %skeleton.
6703 * examples/extexi (normalize): Instead of replacing every %require
6704 argument with the current Bison version, just substitute for
6705 `@value{VERSION}'. This guarantees that we're testing what actually
6706 appears in the documentation.
6707 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
6708 rather than `@VERSION@'.
6710 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
6712 * NEWS: Reword the %language news a bit, and put it earlier.
6714 * src/getargs.c (skeleton_arg): Last arg is now location const *.
6715 Rewrite to simplify the logic.
6716 (language_argmatch): Likewise.
6717 (program_name): We now own this var.
6718 * src/getargs.h (struct bison_language): Use char[] rather than
6721 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
6723 * src/complain.c (program_name): Remove decl; no longer needed.
6724 * src/main.c (program_name): Remove; now belongs to getargs.
6726 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
6728 * NEWS: Document %language.
6730 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
6732 * data/c-skel.m4, data/c++-skel.m4: New files.
6733 * data/glr.c: Complain on push parsers.
6735 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
6737 (Decl Summary): Document %language and %skeleton.
6738 (Command line): Document -L.
6740 * examples/extexi: Rewrite %require directive.
6741 * examples/calc++/Makefile.am: Pass VERSION to extexi.
6743 * src/files.c (compute_exts_from_gc): Look in language structure
6745 (compute_file_name_parts): Check whether .tab should be added.
6746 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
6747 (language, skeleton_arg, language_argmatch): New.
6748 (long_options): Add --language.
6749 (getargs): Use skeleton_arg, add -L/--language.
6750 * src/getargs.h: Include location.h.
6751 (struct bison_language, language, skeleton_arg, language_argmatch): New.
6752 * src/output.c (prepare): Pick default skeleton from struct language.
6753 Don't dispatch C skeletons here.
6754 * src/parse-gram.y (PERCENT_LANGUAGE): New.
6755 (prologue_declaration): Add "%language" rule, use skeleton_arg.
6756 * src/scan-gram.l ("%language"): New rule.
6758 * tests/calc.at: Test %skeleton and %language.
6759 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
6760 (AT_GLR_IF): Look for %skeleton "glr.cc".
6761 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
6762 (AT_YACC_IF): Reject %language.
6764 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
6766 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
6767 since it wasn't used; only the typedef name 'semantic_type' is needed.
6768 Also, omit trailing white space.
6770 * bootstrap: Sync from coreutils.
6771 (gnulib_extra_files): Add build-aux/announce.gen.
6772 (slurp): Adjust .gitignore files like .cvsignore files.
6773 * build-aux/announce-gen: Remove from CVS, since bootstrap
6776 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
6778 Make %push-parser imply %pure-parser. This fixes several bugs; see
6779 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
6780 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
6782 * data/push.c: Don't bother testing b4_push_if when deciding whether
6783 to expand b4_declare_parser_variables globally.
6784 (yypush_parse): Likewise in here.
6786 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
6787 (yy_reduce_print): Reformat M4 for readability.
6789 2006-12-15 Bob Rossi <bob@brasko.net>
6790 and Joel Denny <jdenny@ces.clemson.edu>
6792 * data/push.c (yypstate): Add typedef, and update all uses of
6793 struct yypstate to just yypstate.
6794 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
6796 2006-12-14 Bob Rossi <bob@brasko.net>
6798 * data/push.c (yypush_parse): Declare prototype regardless of
6801 2006-12-14 Bob Rossi <bob@brasko.net>
6803 * data/push.c (yyparse): Remove the prototype and the #define when in
6806 2006-12-13 Bob Rossi <bob@brasko.net>
6808 * data/push.c (yypstate_init): Rename to...
6809 (yypstate_new): ... this and use b4_c_function_def.
6810 (yypstate_delete): New.
6811 (yypush_parse): Change parameters yynval and yynlloc to be const.
6812 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
6813 yypstate_delete functions.
6815 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
6817 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
6818 strange test case titles. Reported by Bob Rossi.
6820 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
6822 * TODO: Add pointer to Sylvain Schmitz's work on static detection
6823 of potential ambiguities in GLR grammers.
6825 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
6827 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
6828 `bison ', use m4_index instead of m4_substr since chopping up a string
6829 containing M4-special characters causes problems here.
6831 Fix a couple of bugs related to special characters in user-specified
6832 file names, and make it easier for skeletons to compute output file
6833 names with the same file name prefix as Bison-computed output file
6835 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
6836 b4_parser_file_name and b4_spec_defines_file instead of
6837 @output_parser_name@ and @output_header_name@, which are now redundant.
6838 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
6839 b4_parser_file_name, b4_spec_defines_file, and the new
6840 @basename(FILENAME@) instead of @output_parser_name@ and
6841 @output_header_name@, which inappropriately escaped the file names as
6843 * src/files.c (all_but_ext): Remove static qualifier.
6844 (compute_output_file_names): Move `free (all_but_ext)' to...
6845 (output_file_names_free): ... here since all_but_ext is needed later.
6846 * src/files.h (all_but_ext): Extern.
6847 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
6848 exactly what MUSCLE_INSERT_STRING used to do.
6849 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
6850 characters are escaped properly.
6851 * src/output.c (prepare): Define muscle file_name_all_but_ext as
6853 For pkgdatadir muscle, maintain previous functionality by using
6854 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
6855 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
6856 digraphs would never be expanded. Hopefully no one has M4-special
6857 characters in his Bison installation path.
6858 * src/scan-skel.l: Don't parse @output_header_name@ and
6859 @output_parser_name@ anymore since they're now redundant.
6860 In @output, use decode_at_digraphs.
6861 Parse a new @basename command that invokes last_component.
6862 (decode_at_digraphs): New.
6863 (BASE_QPUTS): Remove unused.
6864 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
6865 (Output file name): New tests.
6867 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
6869 Warn about output files that are generated by the skeletons and that
6870 conflict with other output files.
6871 * data/glr.c: Don't generate the header file here when glr.cc does.
6872 * src/files.c (file_names, file_names_count): New static globals.
6873 (compute_output_file_names): Invoke output_file_name_check for files
6874 not generated by the skeletons and remove existing checks.
6875 (output_file_name_check): New function that warns about conflicting
6877 (output_file_names_free): Free file_names.
6878 * src/files.h (output_file_name_check): Declare.
6879 * src/scan-skel.l: Invoke output_file_name_check for files generated by
6881 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
6882 (Conflicting output files): New tests.
6884 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6886 * doc/bison.texinfo: Fix a couple of typos.
6888 2006-12-08 Bob Rossi <bob@brasko.net>
6890 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
6892 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
6894 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
6895 (yypush_parse): Rename yypvars argument to yyps and remove redundant

7014 * src/scan-code.l (translate_action): Don't bother invoking
7015 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.

7025 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
7026 has been called previously for the same key.
7027 (muscle_find): Return storage instead of value so that
7028 --enable-gcc-warnings doesn't produce warnings that the return discards
7029 const. aver that the value and storage are the same since storage
7030 could potentially be NULL when value is not.
7031 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
7034 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
7036 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
7037 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives

7076 add a new `char *code' member.
7077 ("{...}"): Declare semantic type as code.
7078 * src/scan-code.h (translate_rule_action):
7079 (translate_symbol_action, translate_code, translate_action): Return

7082 * src/scan-code.l: Likewise.
7083 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
7084 which is "{...}" in the parser.

7090 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
7091 expecting a non-zero exit status sets --leak-check=summary and

7093 this case, and we don't want to hear about it.

7142 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
7143 the parser header file so that gcc doesn't warn.

7196 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
7197 like $@n instead of just @n so that the default %destructor/%printer

7346 messed up the installation of the INSTALL file in some cases.
7348 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
7350 * bootstrap (usage, main program, symlink_to_gnulib): Add option
7351 --copy. Inspired by a suggestion from Bruno Haible.
7353 2006-10-03 Jim Meyering <jim@meyering.net>
7355 * bootstrap: Undo last change to this file, since now gnulib-tool
7356 sticks with the automake default in generating dependencies.
7358 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
7360 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
7361 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
7363 * doc/bison.1: Add copyright notice.
7365 * data/glr.c: Don't include <stdarg.h>; not used.
7367 * NEWS: The -g and --graph options now output graphs in Graphviz
7368 DOT format, not VCG format.
7369 * doc/bison.1: Likewise.
7370 * doc/bison.texinfo (Understanding, Bison Options): Likewise.
7371 * THANKS: Add Satya Kiran Popuri, who proposed the initial version
7373 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00158.html>.
7374 * TODO: Remove Graphviz entry.

7381 * src/main.c (main): Likewise.
7382 * src/print_graph.h: Likewise.
7383 * src/getargs.c (usage): Make usage description more generic.
7384 * src/print_graph.c: Include graphviz.h rather than vcg.h.
7385 (static_graph, fgraph): Remove. All uses changed to pass
7386 arguments instead of sharing a static var.
7387 (print_core, print_actions, print_state, print_graph):
7388 Output graphviz format rather than VCG format.
7389 * tests/.cvsignore: Remove *.vcg; add *.dot.
7390 * tests/output.at: Expect *.dot files, not *.vcg files.
7392 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
7393 accommodates the 2006-10-08 change.
7395 2006-10-11 Bob Rossi <bob@brasko.net>
7397 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.
7398 (b4_yyssa, b4_yyerror_range): New macros.
7399 (struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
7400 (yypvarsinit): Remove init of removed fields.
7401 (yypushparse): Remove use of removed fields; use new macros instead.
7403 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
7405 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
7406 in a push parser. Reindent slightly to match yacc.c better.
7408 2006-10-11 Bob Rossi <bob@brasko.net>
7410 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
7412 (yypvarsinit, yypushparse): Remove init of removed fields.

7415 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
7417 * THANKS: Add Paolo Bonzini and Bob Rossi.
7419 2006-10-08 Paolo Bonzini <bonzini@gnu.org>
7421 * data/c.m4 (b4_copyright, b4_epilogue, b4_location_initial_column,
7422 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
7423 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
7424 b4_define_user_cde and uses): Remove.
7425 (b4_comment, b4_prefix, b4_sync_start): New.
7426 * data/bison.m4: New file, with most of the content removed from c.m4.
7427 * src/muscle_tab.h: Use "do {...} while(0)" throughout.
7428 * src/output.c (output_skeleton): Pass bison.m4.
7429 (prepare): Pass glr_flag and nondeterministic_flag. Pass prefix
7432 2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
7434 Fix test failure reported by Tom Lane in
7435 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
7436 and try to make such failures easier to catch in the future.
7437 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
7438 that's now the caller's responsibility.
7439 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
7440 Set yychar = YYEOF if it's negative.
7441 * tests/actions.at (yylex): Abort if asked to read past EOF.
7442 * tests/conflicts.at (yylex): Likewise.
7443 * tests/cxx-type.at (yylex): Likewise.
7444 * tests/glr-regression.at (yylex): Likewise.
7445 * tests/input.at (yylex): Likewise.
7446 * tests/regression.at (yylex): Likewise.
7447 * tests/torture.at (yylex): Likewise.
7449 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
7451 Fix problems with translating English-language diagnostics.
7452 * bootstrap: Fix bug introduced in recent bootstrap changes, with
7453 respect to bison-runtime pot generation. The YY_ stuff
7454 wasn't being captured.
7455 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
7456 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
7457 * runtime-po/POTFILES.in: Add data/push.c.
7459 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
7461 Merge bootstrap changes from coreutils.
7463 2006-09-28 Jim Meyering <jim@meyering.net>
7465 Automatically generated dependencies are important even
7466 when all of the sources in a directory come from gnulib.
7467 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
7468 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
7470 2006-09-23 Jim Meyering <jim@meyering.net>
7472 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
7474 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
7476 * bootstrap: Add support for --force.
7477 (usage): New function. Describe usage less tersely.
7478 (CVS_only_file): New var.
7480 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
7482 * data/push.c (YYPUSH_MORE): Make it an enum instead.
7483 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
7484 Adjust white space and comments to match GNU style better.
7486 2006-09-20 Bob Rossi <bob@brasko.net>
7488 * data/push.c (yyresult_get): Remove function.
7489 (YYPUSH_MORE): Add #define.
7490 (yypushparse): Modify return value.
7492 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
7494 * stamp-h.in: Remove; no longer needed.
7495 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
7496 Remove config.h, config.hin, intl (no longer created).
7497 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
7500 Sync bootstrap from coreutils, as follows:
7502 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
7504 * bootstrap (symlink_to_gnulib): New function.
7505 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
7506 to copies-of-gnulib.
7507 (cp_mark_as_generated, slurp, gnulib_files):
7508 Avoid making a copy if it's the same as the old version.
7509 (gnulib_files): Add support for this variable (used by Bison).
7511 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
7513 * src/getargs.c (usage): Rework to use conventions similar to
7514 coreutils, to make translation a bit easier and the code a bit
7515 smaller. Problem reported by Tim Van Holder.
7517 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
7519 Use some of gnulib's new modules, taken from coreutils.
7521 * bootstrap: Sync from coreutils, except add support for gnulib_files.
7522 * bootstrap.conf: New file.
7523 (gnulib_modules): Add configmake, inttypes, unistd.
7524 (XGETTEXT_OPTIONS): Add complain, complain_at,
7525 fatal, fatal_at, warn, warn_at, unexpected_end.
7526 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
7527 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
7529 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
7531 (GNULIB_AUTOCONF_SNIPPET): Remove.
7532 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
7534 * lib/.cvsignore: Add inttypes_.h.
7535 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
7536 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
7537 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
7538 no-longer-necessary initializations.
7539 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
7540 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
7541 use the unistd module.
7542 * src/system.h: Likewise.
7543 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
7544 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
7545 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
7546 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
7547 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
7548 * src/system.h: Include inttypes.h unconditionally, now that we
7549 use the inttypes module. Don't bother to include stdint.h, since
7550 inttypes.h now does that for us.
7551 (LOCALEDIR): Remove, now that we use the configmake module.
7552 * src/getargs.c: Include configmake.h.
7553 * src/main.c: Likewise.
7554 * src/output.c: Likewise.
7555 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
7556 not from $abs_top_builddir, since config.h moved.
7559 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
7560 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
7562 * src/parse-gram.y (symbol_declaration): Don't put statements
7563 before declarations; it's not portable to C89.
7564 * src/scan-code.l (handle_action_at): Likewise.
7566 * src/scan-code.l: Always initialize braces_level; the old code
7567 left it uninitialized and therefore had undefined behavior.
7569 Don't attempt to redefine 'assert', since it runs afoul of
7570 systems where standard headers (mistakenly) include <assert.h>.
7571 Instead, define and use our own alternative, called 'aver'.
7572 * src/reader.c: Don't include assert.h, since we no longer
7574 * src/scan-code.l: Likewise.
7575 * src/system.h (assert): Remove, replacing with....
7576 (aver): New function, taking a bool arg. All uses changed.
7577 * src/tables.c (pack_vector): Ensure that aver arg is bool,
7578 not merely an integer.
7580 2006-09-15 Bob Rossi <bob@brasko.net>
7582 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
7583 * data/c.m4 (YYPUSH): New.
7584 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
7585 * src/getargs.c (push_parser): New var.
7586 * src/getargs.h (push_parser): New declaration.
7587 * src/output.c (prepare): Add macro insertion of `push_flag'.
7588 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
7589 (prologue_declaration): Parse %push-parser.
7590 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
7591 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
7592 list of removed lines from the traces observed.
7593 (AT_CHECK_CALC_LALR): Added push parser tests.
7595 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
7597 * NEWS: Version 2.3a.
7598 * configure.ac (AC_INIT): Likewise.
7600 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
7601 "#define YYSTYPE int" that caused "make maintainer-check" to fail
7602 due to header ordering dependencies. I don't know why the #define
7605 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
7606 runtime cost when YYDEBUG is not defined, and so that some tests
7607 that used to fail now work. Problem and initial suggestion by
7609 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
7610 * data/glr.cc (b4_parser_class_name):
7611 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
7612 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
7613 (yydebug_) [YYDEBUG]: New member.
7614 (yycdebug_): Now defined only if YYDEBUG.
7615 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
7616 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
7617 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
7619 (debug_stream, set_debug_stream, debug_level, set_debug_level):
7620 Define only if YYDEBUG.
7621 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
7623 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
7624 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
7625 AT_CHECK_CALC_GLR_CC that are working now.
7627 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
7629 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
7630 We don't need them in glr.cc, and glr.c defines them.
7631 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
7632 assumes that defining it to anything is the same as defining
7633 it to 1. Problem reported by Paolo Bonzini.
7635 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
7637 * data/c.m4 (b4_null, b4_case): Define.
7638 * src/output.c (prepare_symbols): Use b4_null.
7639 (user_actions_output): Use b4_case.
7641 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
7643 * data/glr.c (b4_shared_declarations): Put start-header first,
7644 before any #includes that we generate, so that feature-test
7645 macros work. Problem reported by Michael Deutschmann in
7646 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
7647 * data/lalr1.cc: Likewise.
7648 * doc/bison.texinfo (Prologue): Document that feature-test macros
7649 should be defined before any Bison declarations.
7650 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
7651 that depend on location.hh after, not before, Bison decls, since
7652 we now include location.hh after the first user prologue.
7654 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
7655 Sander Brandenburg in
7656 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
7657 Also, fix minor white space and comment issues.
7658 (Prologue): Mention that it's better to define feature-test macros
7659 before Bison declarations. Problem reported by Michael Deutschmann.
7661 * README-cvs: Fix typo: "&" should be "&&". Problem reported
7663 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
7664 This adjusts to recent gnulib changes.
7666 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
7668 Finish implementation of per-type %destructor/%printer. Discussed
7670 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
7672 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
7673 * NEWS (2.3+): Add a description of this feature to the default
7674 %destructor/%printer description.
7675 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
7676 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
7677 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
7678 list node contains a semantic type.
7679 * src/symtab.c, src/symtab.h: Extend with a table that associates
7680 semantic types with their %destructor's and %printer's.
7681 (semantic_type_from_uniqstr, semantic_type_get,
7682 semantic_type_destructor_set, semantic_type_printer_set): New functions
7683 composing the public interface of that table.
7684 (symbol_destructor_get, symbol_destructor_location_get,
7685 symbol_printer_get, symbol_printer_location_get): If there's no
7686 per-symbol %destructor/%printer, look up the per-type before trying
7688 * tests/actions.at (Per-type %printer and %destructor): New test case.
7689 * tests/input.at (Default %printer and %destructor redeclared):
7690 Extend to check that multiple occurrences of %symbol-default in a
7691 single %destructor/%printer declaration is an error.
7692 (Per-type %printer and %destructor redeclared, Unused values with
7693 per-type %destructor): New test cases.
7695 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
7697 Require default %destructor/%printer to be declared using
7698 %symbol-default instead of an empty symbol list, and start working on
7699 new per-type %destructor/%printer. Discussed at
7700 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
7701 * NEWS (2.3+): Add %symbol-default to example.
7702 * bison.texinfo (Freeing Discarded Symbols): Likewise.
7703 (Table of Symbols): Add entry for %symbol-default.
7704 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
7705 (generic_symlist, generic_symlist_item): New nonterminals for creating
7706 a list in which each item is a symbol, semantic type, or
7708 (grammar_declaration): Use generic_symlist in %destructor and %printer
7709 declarations instead of symbols.1 or an empty list.
7710 (symbol_declaration, precedence_declaration, symbols.1): Update actions
7711 for changes to symbol_list.
7712 * src/reader.c: Update for changes to symbol_list.
7713 * src/scan-code.l: Likewise.
7714 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
7715 * src/symlist.c, src/symlist.h: Extend such that a list node may
7716 represent a semantic type or a %symbol-default in addition to just an
7717 ordinary symbol. Add switched functions for setting %destructor's and
7719 * tests/actions.at, tests/input.at: Add %symbol-default to all default
7720 %destructor/%printer declarations.
7722 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
7724 Whether the default %destructor/%printer applies to a particular symbol
7725 isn't a question of whether the user *declares* that symbol (in %token,
7726 for example). It's a question of whether the user by any means
7727 *defines* the symbol at all (by simply using a char token, for
7728 example). $end is defined by Bison whereas any other token with token
7729 number 0 is defined by the user. The error token is always defined by
7730 Bison regardless of whether the user declares it with %token, but we
7731 may one day let the user define error as a nonterminal instead.
7732 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
7733 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
7734 the meaning of "user-defined".
7735 * tests/actions.at (Default %printer and %destructor for user-declared
7736 end token): Rename to...
7737 (Default %printer and %destructor for user-defined end token): ...
7740 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
7741 computation of whether to apply the default, don't maintain a list of
7742 every Bison-defined symbol. Instead, just check for a first character
7743 of '$', which a user symbol cannot have, and check for the error token.
7745 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
7747 Don't apply the default %destructor or %printer to the error token,
7748 $undefined, or $accept. This change fits the general rule that the
7749 default %destructor and %printer are only for user-declared symbols,
7750 and it solves several difficulties that are described in the new test
7752 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
7753 * tests/actions.at (Default %printer and %destructor are not for error
7754 or $undefined, Default %printer and %destructor are not for $accept):
7757 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
7759 Allow %start after the first rule.
7760 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
7761 when parsing the first rule.
7762 (check_and_convert_grammar): Search for it here after all grammar
7763 declarations have been parsed. Skip midrules, which have dummy LHS
7765 * src/symtab.c (symbol_is_dummy): New function.
7766 * src/symtab.h (symbol_is_dummy): Declare it.
7767 * tests/input.at (%start after first rule): New test.
7769 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
7771 Redo some of the previous commit: add back the ability to use
7772 non-aliased/undeclared string literals since it might be useful to
7773 those declaring %token-table.
7774 * src/reader.c (check_and_convert_grammar): Undo changes in previous
7775 commit: don't worry about complaints from symbols_pack.
7776 * src/symtab.c (symbol_new, symbol_class_set,
7777 symbol_check_alias_consistency): Undo changes in previous commit: count
7778 each string literal as a new symbol and token, assign it a symbol
7779 number, and don't complain about non-aliased string literals.
7780 (symbols_pack): Since symbol_make_alias still does not decrement symbol
7781 and token counts but does still set aliased tokens to the same number,
7782 symbol_pack_processor now leaves empty slots in the symbols array.
7784 * tests/regression.at (Undeclared string literal): Remove test case
7785 added in previous commit since non-aliased string literals are allowed
7787 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
7788 remove unnecessary string literal declarations.
7789 * tests/sets.at (Firsts): Likewise.
7791 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
7793 Don't allow an undeclared string literal, but allow a string literal to
7794 be used before its declaration.
7795 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
7796 symbols_pack complained.
7797 * src/symtab.c (symbol_new): Don't count a string literal as a new
7799 (symbol_class_set): Don't count a string literal as a new token, and
7800 don't assign it a symbol number since symbol_make_alias does that.
7801 (symbol_make_alias): It's not necessary to decrement the symbol and
7802 token counts anymore. Don't assume that an alias declaration occurs
7803 before any uses of the identifier or string, and thus don't assert that
7804 one of them has the highest symbol number so far.
7805 (symbol_check_alias_consistency): Complain if there's a string literal
7806 that wasn't declared as an alias.
7807 (symbols_pack): Bail if symbol_check_alias_consistency failed since
7808 symbol_pack asserts that every token has been assigned a symbol number
7809 although undeclared string literals have not.
7810 * tests/regression.at (String alias declared after use, Undeclared
7811 string literal): New test cases.
7812 (Characters Escapes, Web2c Actions): Declare string literals as
7814 * tests/sets.at (Firsts): Likewise.
7816 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
7818 In the grammar scanner, STRING_FINISH unclosed constructs and return
7819 them to the parser in order to improve error messages.
7820 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
7821 SC_BRACED_CODE, SC_PROLOGUE): Implement.
7822 * tests/input.at (Unclosed constructs): New test case.
7823 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
7826 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
7829 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
7831 Handle string aliases for character tokens correctly.
7832 * src/symtab.c (symbol_user_token_number_set): If the token has an
7833 alias, check and set its alias's user token number instead of its own,
7834 which is set to indicate the alias. Previously, every occurrence of
7835 the character token in the grammar overwrote that alias indicator with
7837 * tests/input.at (String aliases for character tokens): New test.
7839 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
7841 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
7843 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
7845 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
7846 to prevent failures when building on older platforms.
7847 Check for autopoint failure.
7848 Set XGETTEXT_OPTIONS to values that check for C format strings,
7849 so that translators are warned about them (this also helps
7850 prevent core dumps).
7852 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
7853 function, since it simplifies our code a bit.
7855 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
7856 rather than -W, so we don't get bogus warnings about sign comparisons.
7857 Add -Wpointer-arith, since that warning is useful (it reports code
7858 that does not conform to C89 and that some compilers reject).
7859 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
7860 since it's no longer needed.
7862 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
7864 Clean up scanners a bit.
7865 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
7866 definitions so gcc won't warn when obstack_for_string is unused.
7867 * src/scan-code.l: config.h and system.h are already #include'd by
7868 scan-code-c.c, so get rid of them here.
7869 * src/scan-gram.l: Likewise.
7870 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
7871 definitions rather than duplicating the rest of it.
7872 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
7874 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
7876 Suppress signed/unsigned comparison warnings for yycheck.
7877 * data/c.m4 (b4_safest_int_type): New macro.
7878 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
7879 a signed int type, cast it to b4_safest_int_type first.
7880 * data/yacc.c: Likewise.
7881 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
7884 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
7886 * doc/bison.texinfo: Fix some typos.
7888 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
7890 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
7891 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
7893 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
7894 the latest gnulib does this a different way.
7895 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
7896 translation was patched, so stop omitting it.
7898 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
7900 Enable declaration of default %printer/%destructor. Make the parser
7901 use these for all user-declared grammar symbols for which the user does
7902 not declare a specific %printer/%destructor. Thus, the parser uses it
7903 for token 0 if the user declares it but not if Bison generates it as
7904 $end. Discussed starting at
7905 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
7906 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
7908 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
7909 * NEWS (2.3+): Mention.
7910 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
7911 declare a %destructor for a mid-rule's semantic value. It's just
7912 impossible to declare one specific to it.
7913 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
7914 code. Describe default %destructor form.
7915 * src/parse-gram.y (grammar_declaration): Parse default
7916 %printer/%destructor declarations.
7917 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
7918 and symbol_destructor_location_get rather than accessing the destructor
7919 and destructor_location members of struct symbol.
7920 (symbol_printers_output): Likewise but for %printer's.
7921 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
7923 * src/symtab.c (default_destructor, default_destructor_location,
7924 default_printer, default_printer_location): New static global
7925 variables to record the default %destructor and %printer.
7926 (symbol_destructor_get, symbol_destructor_location_get,
7927 symbol_printer_get, symbol_printer_location_get): New functions to
7928 compute the appropriate %destructor and %printer for a symbol.
7929 (default_destructor_set, default_printer_set): New functions to set the
7930 default %destructor and %printer.
7931 * src/symtab.h: Prototype all those new functions.
7932 * tests/actions.at (Default %printer and %destructor): New test to
7933 check that the right %printer and %destructor are called, that they're
7934 not called for $end, and that $$ and @$ work correctly.
7935 (Default %printer and %destructor for user-declared end token): New
7936 test to check that the default %printer and %destructor are called for
7937 a user-declared end token.
7938 * tests/input.at (Default %printer and %destructor redeclared, Unused
7939 values with default %destructor): New tests to check related grammar
7940 warnings and errors.
7942 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
7944 Clean up handling of %destructor for the end token (token 0).
7945 Discussed starting at
7946 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
7948 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
7950 Make the skeletons consistent in how they pop the end token and invoke
7952 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
7953 state, which has token number 0, since this would invoke the
7954 %destructor for the end token.
7955 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
7956 until after shifting the end token, or else it won't be popped.
7957 * data/yacc.c (yyparse): Likewise.
7959 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
7960 it's the end token. Upon termination, destroy an unshifted lookahead
7961 even when it's the end token.
7962 * data/lalr1.cc (yy::parser::parse): Likewise.
7963 * data/yacc.c (yyparse): Likewise.
7965 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
7966 value warnings for the end token when the user gives the end token a
7969 * tests/actions.at (Printers and Destructors): Test all the above.
7971 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
7973 Update to latest gnulib and gettext versions.
7974 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
7976 (gnulib_files): Add m4/warning.m4. Don't worry about files
7977 overwritten by autopoint.
7978 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
7979 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
7981 Don't use autoreconf; instead, invoke autopoint etc. by hand,
7982 so that we can remove the intl files at a better time.
7983 (intl_files_to_remove): Remove aclocal.m4, since it gets
7984 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
7985 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
7986 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
7987 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
7988 Remove datarootdir hack; no longer needed.
7989 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
7990 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
7991 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
7993 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
7994 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
7996 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
7998 * bootstrap: Adjust to today's change to gnulib-tool by invoking
7999 it with --assume-autoconf='latest-stable'.
8001 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
8003 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
8004 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
8006 * src/muscle_tab.h (muscle_grow): Replace the header comments with
8007 those from muscle_tab.c since the old ones are misleading.
8009 2006-07-13 Akim Demaille <akim@epita.fr>
8011 Support %define "KEY" {VALUE}.
8012 * src/scan-code.h, src/scan-code.l (translate_action)
8013 (translate_rule_action, translate_symbol_action, translate_code):
8014 Return char *, not const char *.
8015 * src/parse-gram.y (declaration): Rename as...
8016 (prologue_declaration): this.
8017 (string_content): Remove this nonterminal, use STRING.
8018 (braceless, content, content.opt): New nonterminal.
8020 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
8022 * src/scan-gram.l (getargs.h): Don't include it.
8024 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
8026 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
8027 rather than a for-loop that declares a local bool variable. This
8028 should work around a compatibility problem with a Cray x1e C++
8029 compiler reported by Hung Nguyen in
8030 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
8031 The for-loop was introduced in the 2004-11-17 change but I don't
8032 know why it was needed.
8034 2006-07-12 Akim Demaille <akim@epita.fr>
8036 * data/c.m4: Comment changes.
8038 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
8040 * src/complain.c (error_message, ERROR_MESSAGE): New.
8042 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
8043 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
8045 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
8047 * NEWS: Instead of %union, you can define and use your own union type
8048 YYSTYPE if your grammar contains at least one <type> tag.
8049 Your YYSTYPE need not be a macro; it can be a typedef.
8050 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
8051 (Union Decl, Decl Summary): Document this.
8052 * data/glr.c (YYSTYPE): Implement this.
8053 * data/glr.cc (YYSTYPE): Likewise.
8054 * data/lalr1.cc (YYSTYPE): Likewise.
8055 * data/yacc.c (YYSTYPE): Likewise.
8056 * src/output.c (prepare): Output tag_seen_flag.
8057 * src/parse-gram.y (declaration, grammar_declaration):
8058 Use 'union_seen' rather than 'typed' to determine whether
8059 %union has been seen, since grammars can now be typed without
8061 (symbol_declaration, type.opt, symbol_def):
8062 Keep track of whether a tag has been seen.
8063 * src/reader.c (union_seen, tag_seen): New vars.
8065 * src/reader.h (union_seen, tag_seen, typed): Likewise.
8066 * src/scan-code.l (untyped_var_seen): New variable.
8067 (handle_action_dollar): Adjust to above changes.
8068 (handle_action_dollar, handle_action_at):
8069 Improve overflow checking for outlandish numbers.
8070 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
8071 avoid new diagnostics generated by above changes.
8072 * tests/regression.at (YYSTYPE typedef): Add test to check
8073 for type tags without %union.
8075 * src/symlist.c (symbol_list_length): Return int, not unsigned
8076 int, since callers expect int. This may need to get revisited
8077 once we have proper integer overflow checking.
8079 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
8080 object is now static.
8082 * src/getargs.c (flags_argmatch): Return void, not int,
8083 to pacify ./configure --enable-gcc-warnings.
8085 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
8086 since last_string is already defined to FLEX_PREFIX (last_string).
8088 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
8090 Implement --warnings/-W.
8091 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
8093 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
8095 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
8096 (warnings_args, warnings_types): New.
8097 (getargs, short_options, long_options): Accept -W/--warnings.
8098 Sort the options by alphabetical order, upper case letter right
8099 before its lower case.
8101 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
8103 Change %merge result type clash warnings to errors. Discussed at
8104 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
8105 * src/reader.c (record_merge_function_type): Use complain_at.
8106 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
8107 declared later): Update test case results.
8109 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
8111 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
8112 to be in alphabetical order.
8113 (trace_args): Spelling fixes.
8115 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
8117 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
8118 so they don't collide with user-defined macros.
8119 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
8120 this was never guaranteed, and now that we're using gnulib stdint,
8121 which defines int_fast16_t to long int, the problem is exposed.
8123 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
8125 * data/c.m4 (b4_basename): Simplify a bit, since we don't
8126 need the full POSIX semantics (and weren't implementing them
8129 Adjust to Autoconf 2.60 and today's gnulib.
8130 * bootstrap (gnulib_modules): Add stdint.
8131 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
8132 no longer copies it.
8133 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
8134 since stdint needs the former and wcwidth (which is now required
8135 by mbswidth) needs the latter.
8136 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
8137 work around a compatibility glitch between gettext 0.14.6 and
8139 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
8140 Do not check for uintptr_t, since new stdint module does the right
8142 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
8143 Add stdint.h, stdint_.h, wcwidth.h.
8144 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
8145 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
8146 stdint.m4, wchar_t.m4, wcwidth.m4.
8147 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
8148 usual order for ../lib/*.h files.
8149 (file_name_split): Use last_component, not base_name, to adjust
8151 * src/parse-gram.h: Include <strverscmp.h> in the usual order
8152 for ../lib/*.h files.
8153 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
8154 Define unconditionally, since we now assume the stdint module.
8155 * src/scan-skel.l: Include <dirname.h>.
8156 (BASE_QPUTS): Use last_component, not base_name.
8157 * src/system.h: Include <unlocked-io.h> in the usual order
8158 for ../lib/*.h files. Include <stdint.h> unconditionally,
8159 since we now use the stdint module.
8160 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
8161 HAVE_UINTPTR_T, since we now use the stdint module.
8162 (base_name): Remove decl, since files now include <dirname.h>
8165 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
8167 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
8169 * data/yacc.c, data/glr.c, data/location.cc: Use them.
8170 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
8172 * tests/calc.at: Adjust.
8174 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
8176 * data/c.m4 (b4_basename): New.
8177 (b4_syncline): Also output the location of its invocation (from
8179 (b4_user_action, b4_define_user_action, b4_user_actions)
8180 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
8181 (b4_user_stype): New.
8182 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
8184 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
8186 In the grammar file, the first column is 1 not 0 on the first line as
8187 on every other line.
8188 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
8189 * tests/input.at (Torturing the Scanner): Update output.
8191 * src/scan-gram.l (scanner_cursor): Declare it static.
8193 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
8195 In warnings, say "previous declaration" rather than "first
8197 * src/symtab.c (redeclaration): Do that here.
8198 * src/reader.c (record_merge_function_type): In the case of a result
8199 type clash, report the previous declaration rather than the very first
8200 one in the grammar file.
8201 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
8202 declared later): Add a third declaration to check this behavior.
8203 * tests/input.at (Incompatible Aliases): Update output.
8205 2006-06-27 Akim Demaille <akim@epita.fr>
8207 * doc/Doxyfile.in: New.
8208 * doc/Makefile.am: Use it.
8209 * src/lalr.h, src/symtab.h: Initial doxygenation.
8211 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
8213 Don't miss %merge result type warnings just because the LHS types are
8214 declared after the %merge. This continues the effort of the previous
8216 * src/reader.c (get_merge_function): Don't set the merger type yet.
8217 (record_merge_function_type): New function for setting the merger type
8218 and checking for clashes.
8219 (grammar_current_rule_merge_set): Set the location of the %merge for
8221 (packgram): Invoke record_merge_function_type for each rule now that
8222 all symbol type declarations have been parsed.
8223 * src/reader.h (merger_list.type_declaration_location): New member
8224 storing the location of the first %merge from which the type for this
8225 merging function was derived.
8226 * src/symlist.h (symbol_list.merger_declaration_location): New member
8227 storing the location of a rule's %merge, if any.
8228 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
8229 declared later): New test to catch the error fixed by the above patch.
8231 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
8233 Get action warnings (grammar_rule_check) right even when symbol
8234 declarations appear after the rules. Discussed at
8235 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
8237 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
8238 Don't mistake the type of $$ in a midrule to be that of its parent
8240 * src/reader.c (grammar_current_rule_end): Don't invoke
8241 grammar_rule_check yet since not all symbol declarations may have been
8243 (grammar_midrule_action): Likewise.
8244 Don't record whether the midrule's $$ has been used yet since actions
8245 haven't been translated yet.
8246 Record the midrule's parent rule and its RHS index within the parent
8248 (grammar_current_rule_action_append): Don't translate the action yet
8249 since not all symbol declarations may have been parsed yet and, thus,
8250 warnings about types for $$, $n, @$, and @n can't be reported yet.
8251 (packgram): Translate the action and invoke grammar_rule_check now that
8252 all symbol declarations have been parsed.
8253 * src/scan-code.l (handle_action_dollar): Now that this is invoked
8254 after parsing the entire grammar file, the symbol list here in the case
8255 of a midrule is actually the midrule's empty RHS, so reference its
8256 parent rule's RHS where necessary.
8257 On the other hand, now that you can already know it's a midrule, you
8258 aren't forced to think $$ has the same type as its parent rule's $$.
8259 (handle_action_at): In the case of a midrule, reference the parent rule
8261 * src/symlist.c (symbol_list_new): Initialize new midrule-related
8263 (symbol_list_length): Now that this is invoked after all rules have
8264 been parsed, a NULL symbol (rather than a NULL symbol list node)
8265 terminates a rule. symbol_list_print already does this correctly.
8266 * src/symlist.h (symbol_list.midrule_parent_rule,
8267 symbol_list.midrule_parent_rhs_index): New members so that midrules can
8268 remember their relationships with their parents.
8269 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
8270 fixed by the above patch.
8271 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
8273 (Unused values): ... this old test case and...
8274 (Unused values before symbol declarations): ... this new test case.
8275 This one is the same as `Unused values' except that all symbol
8276 declarations appear after the rules in order to catch the rest of the
8277 errors fixed by the above patch.
8279 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
8282 * src/reader.c (current_rule): Declare it static since it's no longer
8283 used outside this file.
8284 (grammar_current_rule_action_append): Remove redundant arguments from
8285 translate_rule_action invocation.
8286 * src/reader.h (current_rule): Remove this unused extern.
8287 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
8288 * src/scan-code.l (translate_rule_action): Likewise.
8290 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
8292 Clean up yesterday's patch.
8293 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
8295 * src/reader.c (grammar_current_rule_action_append): ... here for
8296 consistency with grammar_current_rule_symbol_append.
8297 * tests/regression.at (Braced code in declaration in rules section):
8298 Make yyerror and yylex static as usual.
8300 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
8302 Fix bug that mistakes braced code in a declaration in the rules section
8303 to be a rule action. Mentioned at
8304 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
8305 * src/scan-gram.l: Move midrule action detection from the start of the
8306 scanning of any braced code to...
8307 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
8308 action. For readability, use $2 and @2 rather than the equivalent
8310 * tests/regression.at (Braced code in declaration in rules section):
8311 New test to catch the error fixed by the above patch.
8313 Work on code readability some.
8314 * src/scan-code.l (current_rule): Get rid of this misleading and
8315 redundant declaration: it's actually extern'ed in reader.h.
8316 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
8317 translate_action): Add a rule argument and use it instead of the global
8319 (translate_rule_action): This already receives current_rule through an
8320 argument, so pass it on to translate_action instead of assigning
8321 current_rule to current_rule.
8322 (translate_symbol_action, translate_code): Pass rule = NULL to
8325 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
8327 Rename %before-definitions to %start-header and %after-definitions to
8328 %end-header. Don't use these declarations to separate pre-prologue
8329 blocks from post-prologue blocks. Add new order-independent
8330 declarations %before-header and %after-header as alternatives to the
8331 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
8332 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
8333 * NEWS (2.3+): Update for these changes.
8334 * data/glr.c (b4_before_definitions): Update to...
8335 (b4_start_header): ... this.
8336 (b4_after_definitions): Update to...
8337 (b4_end_header): ... this.
8338 * data/glr.cc: Likewise.
8339 * data/lalr1.cc: Likewise.
8340 * data/yacc.c: Likewise.
8341 * doc/bison.texinfo (The prologue): Update names, and replace remaining
8342 prologue blocks with %*-header declarations.
8343 (Calc++ Parser): Likewise.
8344 (Decl Summary): Update names.
8345 (Table of Symbols): Update description.
8346 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
8347 (PERCENT_END_HEADER): ... this.
8348 (PERCENT_BEFORE_DEFINITIONS): Update to...
8349 (PERCENT_START_HEADER): ... this.
8350 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
8351 (declaration): Update token names and m4 macro names.
8352 When parsing %end-header and %start-header, invoke translate_code
8353 before muscle_code_grow, and no longer set global booleans to remember
8354 whether these declarations have been seen.
8355 Parse new %after-header and %before-header.
8356 * src/reader.c (before_definitions, after_definitions): Remove.
8357 (prologue_augment): Accept a new bool argument to specify whether to
8358 augment the pre-prologue or post-prologue.
8359 * src/reader.h (before_definitions, after_definitions): Remove these
8361 (prologue_augment): Add new bool argument.
8362 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
8363 (PERCENT_END_HEADER): ... this.
8364 (PERCENT_BEFORE_DEFINITIONS): Update to...
8365 (PERCENT_START_HEADER): ... this.
8366 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
8367 * tests/actions.at (Printers and Destructors): Update names.
8369 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
8371 Add comparison operators for C++ location classes. Discussed at
8372 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
8373 * data/c++.m4 (b4_define_location_comparison): New boolean %define
8374 declaration indicating whether filename_type has an operator==. If
8375 filename_type is `std::string', it defaults to `1', `0' otherwise.
8376 * data/location.cc: Iff b4_define_location_comparison is `1', add
8377 operator== and operator!= for class position and for class location.
8380 * src/scan-action.l: Remove unused file.
8381 * src/symtab.c (symbol_printer_set): Use printer_location not
8382 destructor_location.
8383 * src/symtab.h (struct symbol): Replace incorrect source comment for
8385 * tests/input.at (Incompatible Aliases): Update output with correct
8388 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
8390 Don't put the pre-prologue in the header file. For the yacc.c code
8391 file and the glr.c header and code files, move the pre-prologue before
8392 the token definitions. Add new %before-definitions and
8393 %after-definitions to declare code that will go in both the header file
8394 and code file. Discussed at
8395 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
8396 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
8398 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
8399 * NEWS (2.3+): Describe these changes.
8400 * data/glr.c (b4_pre_prologue): Move from within to before...
8401 (b4_shared_declarations): ... this.
8402 Add new b4_before_definitions before b4_token_enums.
8403 Add new b4_after_definitions at the end.
8404 * data/glr.cc (b4_pre_prologue): Replace with...
8405 (b4_before_definitions): ... this in the header file.
8406 (b4_after_definitions): New near the end of the header file.
8407 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
8408 code file right before including the header file.
8409 (b4_before_definitions): New in the previous position of
8410 b4_pre_prologue in the header file.
8411 (b4_after_definitions): New near the end of the header file.
8412 * data/yacc.c: Clean up some m4 quoting especially in the header file.
8413 (b4_token_enums_defines): In the code file, move to right before
8414 YYSTYPE for consistency with the header file.
8415 (b4_before_definitions): New right before b4_token_enums_defines in
8416 both the header and code file.
8417 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
8418 header and code file.
8419 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
8420 of prologues for %union dependencies.
8421 (Decl Summary): In %defines description, mention the effect of
8422 %before-definitions and %after-definitions on the header file.
8423 (Calc++ Parser): Forward declare driver in a %before-definitions rather
8424 than in the pre-prologue so that make check succeeds.
8425 (Table of Symbols): Add entries for %before-definitions and
8427 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
8428 %before-definitions.
8429 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
8430 (declaration): Parse those declarations and append to
8431 b4_before_definitions and b4_after_definitions, respectively.
8432 * src/reader.c (before_definitions, after_definitions): New bools to
8433 track whether those declarations have been seen.
8434 (prologue_augment): Add to the post-prologue if %union,
8435 %before-definitions, or %after-definitions has been seen.
8436 * src/reader.h (before_definitions, after_definitions): New extern's.
8437 * src/scan-gram.l: Scan the new declarations.
8438 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
8439 prologue block in a %before-definitions or a %after-definitions based
8440 on whether the %union is declared.
8441 * tests/regression.at (Early token definitions with --yacc, Early token
8442 definitions without --yacc): Move tests for token definitions into the
8443 post-prologue since token names are no longer defined in the
8446 2006-06-20 Akim Demaille <akim@epita.fr>
8448 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
8449 (symbol_get): Use it.
8450 * src/parse-gram.y: Use it.
8452 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
8454 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
8455 build succeeds when configured with --enable-gcc-warnings.
8457 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
8459 * src/parse-gram.y (char_name): New function.
8460 (CHAR, STRING, string_content): For %printer, properly escape.
8461 (ID): Prefer fputs to fprintf.
8462 (id): Reindent to be consistent with other rules.
8463 Properly quote char.
8465 The Translation Project changed its way of publishing translations
8466 to maintainers. I haven't received any responses to my request
8467 for supporting the old way, or for documenting the new way. I
8468 have modified 'bootstrap' to use screen scraping
8469 (in this case, HTML scraping). This is unreliable and inelegant,
8470 but I don't see any better way. Yuck.
8471 * bootstrap (TP_URL, WGET_COMMAND): New vars.
8472 (get_translations): New function, which uses HTML scraping to
8473 deduce locations of latest translations.
8474 Use this function to grab both bison and bison-runtime .po files.
8475 Don't bother priming the pump for the runtime-po domain any more,
8476 as it's now translated better than bison is.
8478 2006-06-19 Akim Demaille <akim@epita.fr>
8480 * src/scan-gram.l: No longer "parse" things after `%union' until
8481 `{'. Rather, return a single "%union" token.
8482 No longer make symbols: return strings, and leave the conversion
8483 to symbols to the parser.
8484 (SC_PRE_CODE, token_type): Remove.
8485 * src/parse-gram.y (%union): New field `character'.
8488 (ID, ID_COLON): Now that the scanner no longer makes them
8489 identifiers, adjust all uses to invoke symbol_get.
8490 (id_colon): New, wraps the conversion from string to symbol.
8491 (%union): Accept a possible union_name.
8492 (symbol): Now can be a char.
8493 * data/c.m4 (b4_union_name): Leave a default value.
8494 * data/glr.c, data/yacc.c: Use it.
8496 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
8498 For associating token numbers with token names for "yacc.c", don't use
8499 #define statements unless `--yacc' is specified; always use enum
8500 yytokentype. Most important discussions start at:
8501 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
8502 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
8504 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
8505 * NEWS (2.3+): Mention.
8506 * data/c.m4 (b4_yacc_if): New.
8507 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
8509 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
8510 on token name definitions.
8511 * src/getargs.c (usage): Capitalize `Yacc' in English.
8512 * src/output.c (prepare): Define b4_yacc_flag.
8513 * tests/regression.at (Early token definitions): Test that tokens names
8514 are defined before the pre-prologue not just before the post-prologue.
8515 Remove this test case and copy to...
8516 (Early token definitions with --yacc): ... this to test #define's.
8517 (Early token definitions without --yacc): ... and this to test enums.
8519 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
8521 * NEWS: Reword the post-2.3 change to not be so optimistic about
8522 removing the old "look-ahead" spelling.
8523 Update previous look-ahead/lookahead change reports.
8524 * REFERENCES: look-ahead -> lookahead (since that's
8525 what he actually wrote).
8526 * doc/refcard.tex: look ahead -> lookahead,
8527 look-ahead -> lookahead
8529 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
8531 For consistency, use `lookahead' instead of `look-ahead' or
8532 `look_ahead'. Discussed starting at
8533 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
8535 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.

8542 (lookahead_set): Rename from look_ahead_set.
8543 (flush_reduce): Rename argument look_ahead_tokens to lookahead_tokens.
8544 (resolve_sr_conflict): Rename local look_ahead_tokens to
8545 lookahead_tokens, and update other uses.
8546 (flush_shift, set_conflicts, conflicts_solve, count_sr_conflicts,
8547 count_rr_conflicts, conflicts_free): Update uses.
8548 * src/getargs.c (report_args): Move "lookahead" before alternate
8550 (report_types): Update uses.

8572 (print_core): Update uses.
8573 * src/state.c: Update English in comments.
8574 (reductions_new): Update uses.

8608 * TODO: Add request from Nelson H. F. Beebe to be able to install
8609 Bison without installing the yacc script.
8611 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
8613 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
8614 and yytext if they're already #define'd.
8615 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
8616 * src/scan-code-c.c: ... here.
8617 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
8620 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
8622 Get Bison to build again when configured with --enable-gcc-warnings.
8623 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
8625 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
8626 loc argument as it shadows a global.

8644 2006-06-06 Akim Demaille <akim@epita.fr>
8646 Extract the parsing of user actions from the grammar scanner.
8647 As a consequence, the relation between the grammar scanner and
8648 parser is much simpler. We can also split "composite tokens" back
8650 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
8651 * src/scan-gram.l (add_column_width, adjust_location): Move to and
8653 * src/location.h, src/location.c (add_column_width)
8654 (location_compute): these.
8655 Fix the column count: the initial column is 0.
8656 (location_print): Be robust to ending column being 0.
8657 * src/location.h (boundary_set): New.
8658 * src/main.c: Adjust to scanner_free being renamed as

8665 which is now, again, a separate token.
8666 Adjust all dependencies.
8667 Whereever actions with $ and @ are used, use translate_code.
8668 (action): Remove this nonterminal which is now useless.
8669 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
8670 (grammar_current_rule_action_append): Use translate_code.
8671 (packgram): Bound check ruleno, itemno, and rule_length.

8679 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
8680 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
8681 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
8682 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
8683 Move these declarations, and...
8684 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
8686 * src/flex-scanner.h: this new file.
8687 * src/scan-gram.l (rule_length, rule_length_overflow)
8688 (increment_rule_length): Remove.
8689 (last_braced_code_loc): Rename as...
8690 (gram_last_braced_code_loc): this.
8691 Adjust to the changes of the parser.
8692 Move all the handling of $ and @ into...
8693 * src/scan-code.l: here.
8694 * src/scan-gram.l (handle_dollar, handle_at): Remove.
8695 (handle_action_dollar, handle_action_at): Move to...
8696 * src/scan-code.l: here.
8697 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
8698 scan-code.h, scan-code-c.c, scan-gram.h.
8699 (EXTRA_bison_SOURCES): Add scan-code.l.
8700 (BUILT_SOURCES): Add scan-code.c.
8701 (yacc): Be robust to white spaces.
8703 * tests/conflicts.at, tests/input.at, tests/reduce.at,
8704 * tests/regression.at: Adjust the column numbers.
8705 * tests/regression.at: Adjust the error message.
8707 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
8709 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
8710 Use Akim's wording from
8711 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
8713 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
8715 Between Bison releases, manually append `+' to the previous Bison
8716 release number, and use that as a signal to automatically print the
8717 ChangeLog's CVS Id keyword from --version. Discussed starting at
8718 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
8719 * ChangeLog: Add Id header.
8720 * configure.ac (AC_INIT): Append `+' to `2.3'.
8721 * src/.cvsignore: Add revision.c.
8722 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
8723 (BUILT_SOURCES): Add revision.c.
8724 (revision.c): New target rule. This file defines a new global variable
8725 named revision. It initializes it with either the Id from ChangeLog
8726 or, if VERSION doesn't contain `+', with the empty string.
8727 * src/getargs.c (version): Print the value of revision.
8728 * src/revision.h: Extern revision.
8730 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8732 * NEWS: Version 2.3.
8733 * configure.ac (AC_INIT): Likewise.
8735 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
8737 * data/glr.c (YYRECOVERING): Define to be a function-like macro
8738 with no arguments, not as an object-like macro. This is for
8739 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
8740 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
8741 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
8744 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
8746 * src/getargs.c (usage): Back out yesterday's modification of the
8747 --help output so that we don't have to wait for translation before
8750 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
8752 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
8753 Problem reported by Akim Demaille.
8755 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
8757 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
8759 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
8761 * data/yacc.c (yy_reduce_print): Omit trailing white space in
8762 generated source code. Problem reported by Frans Englich in
8763 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
8765 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
8767 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
8768 shell, not within 'make', so that 'make' by an ordinary builder
8769 (using GNU make) does not worry about configuring gzip. This also
8770 works around a bug reported independently by Keith Thompson and by
8771 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
8772 stderr rather than stdout, messing up the build logs.
8774 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
8776 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
8777 to make sure that YYID will never be unused. This fixes a 'make
8778 maintainer-check' failure caused by the recent changes to the 'Trivial
8779 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
8781 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
8783 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
8785 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
8786 state before an empty RHS is always resolved here. Only the location
8787 of that state is guaranteed to be resolved, and that's enough. This
8788 fixes the remaining bug reported by Derek M. Jones in
8789 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
8790 * tests/glr-regression.at (Uninitialized location when reporting
8791 ambiguity): Test the above case.
8792 Also, the embedded comments in this test case claim it checks the case
8793 of an empty RHS that has inherited the initial location. However, the
8794 corresponding LHS was already resolved, so yyresolveLocations didn't
8795 actually have reason to modify it. Fix this by forcing
8796 nondeterministic operation at the beginning of the parse.
8798 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8800 * data/c.m4 (b4_yy_symbol_print_generate):
8801 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
8802 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
8803 of the bugs reported today by Derek M Jones in
8804 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
8805 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
8806 defined to be a type name without parens or brackets.
8807 (Location Type): Similarly for YYLTYPE.
8808 * tests/regression.at (Trivial grammars): Put in a test for this
8809 bug that will be caught by 'make maintainer-check' (though not,
8810 alas, by 'make check' unless your compiler is picky).
8812 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8814 * NEWS: Version 2.2.
8815 * configure.ac (AC_INIT): Likewise.
8817 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
8819 * data/glr.c (yyreportTree): Make room in yystates for the state
8820 preceding the RHS. This fixes the segmentation fault reported by Derek
8822 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
8823 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
8824 to the user. Reported for yyreportTree by Derek M. Jones later in the
8826 * THANKS: Add Derek M. Jones.
8827 Update my email address.
8828 Fix typo in Steve Murphy's name.
8830 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8832 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
8833 checking against YYLAST that caused the parser to miss a potential
8834 alternative in its diagnostic.
8835 Problem reported by Maria Jose Moron Fernandez in
8836 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
8837 * data/lalr1.cc (yysyntax_error_): Likewise.
8838 * data/yacc.c (yysyntax_error): Likewise.
8839 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
8840 tokens, in case we run into an older C compiler.
8841 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
8842 Use them to check for the off-by-one error fixed above.
8844 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
8845 YYSIZE_T, not size_t.
8846 * tests/regression.at (Trivial grammars): New test, to catch
8847 the error fixed by the above patch.
8849 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
8851 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
8853 Reported by Steve Murphy.
8855 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
8857 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
8858 * data/glr.cc: b4_location_flag is now b4_locations_flag.
8860 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
8862 Implement --trace=m4.
8863 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
8864 * src/output.c (output_skeleton): When set, pass -dV to m4.
8866 Factor the handling of flags in m4.
8867 * src/output.c (prepare): Rename the muscle names debug, defines,
8868 error_verbose to debug_flag, defines_flag, error_verbose_flag.
8869 * data/c.m4: Adjust.
8870 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
8871 Use b4_define_flag_if to define other b4_FLAG_if macros.
8872 (b4_location_if): As a consequence, rename as...
8873 (b4_locations_if): this, for consistency.
8874 Adjust all the skeletons.
8876 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
8878 * etc/bench.pm: Shorten bench names.
8880 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
8882 * src/output.h, src/output.c (error_verbose): Move to...
8883 * src/getargs.h, src/getargs.c: here.
8885 Adjust dependencies.
8887 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8889 * data/c.m4 (b4_copyright): Put the special exception for Bison
8890 skeletons here, so we don't have to put it in each skeleton. All
8891 uses changed. Suggested by Akim Demaille. Also, wrap the
8892 copyright notice, in case it is longer than 80 columns. Replace
8893 comma by newline after title.
8895 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8897 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
8898 incompatibility, not a bug. Mention that it wasn't fixed as of
8901 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
8903 * examples/extexi: Enforce the precedence of concatenation over
8905 Reported by Tommy Nordgren.
8907 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
8909 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
8910 with the member "token".
8911 Reported by Martin Nylin.
8913 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
8915 * data/glr.c: Switch to Bison 2.2 special-exception language in
8916 the copyright notice. Use more-regular format for titles and
8918 * data/glr.cc: Likewise.
8919 * data/location.cc: Likewise.
8920 * data/yacc.cc: Likewise.
8921 * doc/bison.texinfo (Conditions): Document this.
8922 * NEWS: likewise. Upgrade version to 2.2.
8924 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
8926 * data/glr.cc: Remove dead code.
8928 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
8930 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
8931 that variable and the line breaks the bootstrap. Problem reported
8932 by Juan M. Guerrero.
8934 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
8936 * doc/bison.texinfo (Multiple start-symbols): New.
8938 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
8940 * etc/README, etc/bench.pl: New.
8942 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
8944 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
8946 Reported by Mickael Labau.
8947 * tests/input.at (Torturing the Scanner): Test it.
8949 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
8951 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
8952 Problem reported by Bob Rossi.
8954 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
8956 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
8957 and didn't really work.
8958 For the index, use @ifnotinfo, not @iftex.
8959 Minor cleanups of spacing and terminology.
8961 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
8963 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
8964 of AT_NAME_PREFIX when %name-prefix is not used.
8966 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
8968 Apply --prefix to C++ skeletons too: they change the namespace.
8969 The test suite already exercize these cases.
8970 * data/c++.m4 (b4_namespace): New.
8971 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
8972 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
8973 * data/yacc.c, data/glr.c: Remove a useless `[]'.
8974 * doc/bison.texinfo: Document it.
8975 (Option Cross Key): Use @multitable in all formats. It looks
8976 nicer, even in TeX outputs.
8977 (Rules): Use the same code whatever the output type is.
8978 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
8979 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
8980 * tests/calc.at: Use it, instead of hard coding `yy'.

8997 * doc/bison.texinfo (Calc++ Scanner): Use it.
8999 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
9001 Fix two nits reported by twlevo, plus one more that I discovered.
9003 * src/assoc.h (assoc_to_string): Give a name to the arg, as
9004 this is the usual Bison style.
9005 * src/location.h (location_print): Likewise.
9007 * src/reader.h (token_name): Likewise.
9009 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
9011 Fix some nits reported by twlevo.
9012 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
9013 and "POSIX". Use more-modern syntax for URLs. Mention C++
9014 and ask for Java. Don't hardwire OS version numbers. Add
9016 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
9017 * src/conflicts.c (solved_conflicts_obstack): Now static.
9019 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
9021 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
9022 page. Say "you can use it" not "you may use it" as on the web page;
9023 we're describing capabilities not granting permission.
9025 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
9027 * data/glr.c (yyresolveLocations): Rename local variables to avoid
9028 shadowing warnings. Use usual patter for iterating through RHS.
9029 * tests/glr-regression.at
9030 (Uninitialized location when reporting ambiguity):
9031 Modify yylex so that it uses its argument, rather than trying
9032 to rely on ARGSUSED (which doesn't work for gcc with warnings).
9033 const char -> char const.
9035 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
9036 Don't use tabs inside commands; it messes up 'ps'.
9037 Problem reported by twlevo.
9039 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
9041 * tests/glr-regression.at (Uninitialized location when reporting
9042 ambiguity): New test case.
9043 * data/glr.c (yyresolveLocations): New function, which uses
9045 (yyresolveValue): Invoke yyresolveLocations before reporting an
9047 * doc/bison.texinfo (Default Action for Locations): Note
9048 YYLLOC_DEFAULT's usage for ambiguity locations.
9049 (GLR Semantic Actions): Cross-reference those notes.
9051 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
9053 * tests/glr-regression.at (Leaked semantic values when reporting
9054 ambiguity): Remove unnecessary union and type declarations.
9055 (Leaked lookahead after nondeterministic parse syntax error): New test
9057 * data/glr.c (yyparse): Check for zero stacks remaining before
9058 attempting to shift the lookahead so that you don't lose it.
9060 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
9062 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
9063 * tests/glr-regression.at (Leaked semantic values when reporting
9064 ambiguity): New test case.
9065 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
9066 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
9067 now unnecessary yystackp parameter.
9068 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
9069 destructors can be called.
9071 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
9072 in existing testcases.
9074 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
9076 Don't leak semantic values for parent RHS when a user action cuts the
9077 parser, and clean up related code a bit.
9078 * tests/glr-regression.at (Leaked merged semantic value if user action
9079 cuts parse): Rename to...
9080 (Leaked semantic values if user action cuts parse): ... this. Add check
9081 for leaked parent RHS values.
9082 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
9083 between an unresolved state (non-empty chain of semantic options) and
9084 an incomplete one (signaled by an empty chain).
9085 (yyresolveStates): Document the interface. Move all manipulation of a
9086 successfully or unsuccessfully resolved yyGLRState to...
9087 (yyresolveValue): ... here so that yyresolveValue always leaves a
9088 yyGLRState with consistent data and thus is easier to understand.
9089 Remove the yyvalp and yylocp parameters since they are always just
9090 taken from the yys parameter. When reporting a discarded merged value
9091 in debugging output, note that it is incompletely merged. Document the
9093 (yyresolveAction): If resolving any of the RHS states fails, destroy
9094 them all rather than leaking them. Thus, as long as user actions are
9095 written to clean up the RHS correctly, yyresolveAction always cleans up
9096 the RHS of a semantic option. Document the interface.
9098 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
9100 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
9101 led to a segmentation fault in GNU Pascal. Problem reported
9104 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
9106 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
9107 mid-rule action inside a nonterminal symbol in order to declare a
9108 destructor for its semantic value.

9115 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||

9117 declarations of malloc and free, to avoid problems with
9118 incompatible declarations (using 'throw') C++'s stdlib.h. This
9119 should fix Debian bug 340012

9157 More portability fixes for problems summarized by Nelson H. F. Beebe.
9159 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
9160 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
9162 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
9163 nodist_PROGRAMS, since we don't need to actually compile the
9164 example if we're just doing a plain 'make'. This avoids bothering
9165 the installer unnecessarily about problems due to weird C++
9168 2006-02-06 Paul Eggert <eggert@cs.ucla.edu>
9170 More portability fixes for problems summarized by Nelson H. F. Beebe.
9172 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
9173 than #include "...", and compile with -I'.'. The old method was
9174 not portable, according to Posix and the C standard, and it does
9175 not work with Sun C 5.7, where previous #line directives affect
9176 the working directory used in later #include "..." directives.

9191 Work around portability problems summarized by Nelson H. F. Beebe in
9192 <http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.
9194 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
9195 that '#include <string>' works.
9197 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
9198 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
9199 "warning: sorry: semantics of inline function static data `const
9200 unsigned char translate_table[262]' are wrong (you'll wind up with
9203 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
9204 or, xor to not_, and_, or_, and xor_, respectively. This works
9205 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
9206 random system header somewhere that includes the equivalent of
9209 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
9210 -E" works; it apparently doesn't work with PathScale EKO Compiler
9213 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
9215 During deterministic GLR operation, user actions should be able to
9216 influence the parse by changing yychar. To make this easier to fix and
9217 to make glr.c easier to evolve in general, don't maintain yytoken in
9218 parallel with yychar; just compute yytoken when needed.
9219 * tests/glr-regression.at (Incorrect lookahead during deterministic
9220 GLR): Check that setting yychar in a user action has the intended
9222 * data/glr.c (yyGLRStack): Remove yytokenp member.
9223 (yyclearin): Don't set *yytokenp.
9224 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
9225 yychar rather than *yytokenp to determine the current lookahead.
9226 Compute yytoken locally when needed.
9227 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
9230 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
9231 after `--report' documentation.

9239 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
9241 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
9242 all the test at once. This makes the output easier to read in the
9245 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
9246 got from <http://bro-ids.org/download.html>. The bug is that
9247 when two actions appeared in succession, the second one was
9248 scanned before the first one was added to the grammar rule
9249 as a midrule action. Bison then output the incorrect warning
9250 "parse.y:905.17-906.36: warning: unused value: $3".
9251 * src/parse-gram.y (BRACED_CODE, action): These are no longer
9252 associated with a value.
9253 (rhs): Don't invoke grammar_current_rule_action_append.
9254 (action): Invoke it here instead.
9255 * src/reader.c (grammar_midrule_action): Now extern.
9256 (grammar_current_rule_action_append): Don't invoke
9257 grammar_midrule_action; that is now the scanner's job.
9258 * src/reader.h (last_string, last_braced_code_loc):
9259 (grammar_midrule_action): New decls.
9260 * src/scan-gram.l (last_string): Now extern, sigh.

9262 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
9263 rule already has an action.
9264 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
9265 * tests/input.at (AT_CHECK_UNUSED_VALUES):
9266 Add some tests to check that the above changes fixed the bug.
9268 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
9270 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
9271 All used changed. Check whether the symbol has a destructor,
9272 not whether it is typed.
9273 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
9274 that the values are still reported as unused. All line numbers

9288 Work around a bug in Pike 7.0, and give the Pike folks a
9289 better way to override the usual int widths.
9290 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
9291 user can override the types.

9298 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.

9318 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>

9322 of the changelog every time.
9323 * Makefile.maint: Sync from coreutils a bit better.

9504 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
9506 * doc/bison.texinfo: Fix some typos.
9507 (GLR Semantic Actions): New subsection discussing special

9509 (Actions): Mention look-ahead usage of yylval.
9510 (Actions and Locations): Mention look-ahead usage of yylloc.
9511 (Special Features for Use in Actions): Add YYEOF entry and mention it
9512 in the yychar entry.
9513 In the yychar entry, remove mention of the local yychar case (pure
9514 parser) since this is irrelevant information when writing semantic
9515 actions and since it's already discussed in `Table of Symbols' where
9516 yychar is otherwise described as an external variable.
9517 In the yychar entry, don't call it the `current' look-ahead since it
9518 isn't when semantic actions are deferred.
9519 In the yychar and yyclearin entries, add note about deferred semantic
9521 Add yylloc and yylval entries discussing look-ahead usage.
9522 (Look-Ahead Tokens): When discussing yychar, don't call it the
9523 `current' look-ahead, and do mention yylval and yylloc.
9524 (Error Recovery): Cross-reference `Action Features' when mentioning
9526 (Table of Symbols): In the yychar entry, don't call it the `current'
9528 In the yylloc and yylval entries, mention look-ahead usage.
9530 2006-01-08 Joel E. Denny <jdenny@ces.clemson.edu>

9534 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
9536 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
9537 use during nondeterministic operation to track which stacks have
9538 actually needed the current lookahead.
9539 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
9540 Allocate, deallocate, resize, and otherwise shuffle space for
9541 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
9542 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
9543 appropriately during nondeterministic operation.
9544 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
9545 members to store the current lookahead to be used by the deferred
9547 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
9548 from which the RHS is taken. Set the lookahead members of the new
9549 yySemanticOption according to the lookahead status for stack yyk.
9550 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
9551 yyaddDeferredAction.
9552 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
9553 members of yySemanticOption before invoking yyuserAction, and then set
9554 them back to their current values afterward.

9558 titles for consistency.

9561 char value < 128 in main.
9562 (Incorrect lookahead during deterministic GLR): New test case.
9563 (Incorrect lookahead during nondeterministic GLR): New test case.
9565 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
9567 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
9568 !yyvaluep as signal that no semantic value is available to print.
9569 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try
9570 to print a semantic value.

9577 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
9579 * data/glr.c (yyresolveValue): When merging semantic options, if at
9580 least one user action succeeds but a later one cuts the parse, then
9581 destroy the semantic value before returning rather than leaking it.
9582 (yyresolveStates): If a user action cuts the parse and thus
9583 yyresolveValue fails, ignore the (unset) semantic value rather than
9584 corrupting the yyGLRState, and empty the semantic options list since
9585 the user actions should have called all necessary destructors.
9586 Simplify code with YYCHK.
9587 * tests/glr-regression.at (Corrupted semantic options if user action
9588 cuts parse): New test case.
9589 (Undesirable destructors if user action cuts parse): New test case.
9590 Before applying any of this patch, this test case never actually failed

9714 Use increment_rule_length rather than incrementing it by hand.
9715 (adjust_location, handle_syncline): Diagnose overflow.

9812 for semantic values was leaked instead.
9814 2005-12-21 Joel E. Denny <address@hidden>

9831 `if (YYID (N))' to pacify lint.
9833 2005-12-21 Akim Demaille <akim@epita.fr>

9856 * djgpp/config.sed: Replace every occurence of the file name
9857 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

9887 sed out the final state number.
9889 Work around portability problem on Solaris 10: flex-generated
9890 files include <stdio.h> before <config.h>, which messes up
9891 because the latter defines __EXTENSIONS__. Address the problem
9892 by creating two new little files that include <config.h> first,
9893 then include the flex-generated files. Rewrite everyone else
9894 to include <config.h> first, as well.
9895 * lib/timevar.c: Always include "config.h".

9942 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
9943 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
9945 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.

9970 * data/yacc.c: Say "parser skeleton" rather than "file", since
9971 it's no longer just a file.
9972 * data/glr.c: Grant a special exception for C GLR parsers, that
9973 reads like the already-existing exception for C LALR(1) parsers.

10094 2005-11-09 Albert Chin-A-Young <china@thewrittenword.com>
10096 * m4/cxx.m4, examples/Makefile.am: Don't build

10101 * src/scan-skel.l: Use a couple of asserts.
10103 2005-11-03 Akim Demaille <akim@epita.fr>
10105 In some (weird) cases, the final state number is incorrect.
10106 Reported by Alexandre Duret-Lutz.

10129 2005-10-30 Paul Eggert <eggert@cs.ucla.edu>
10131 * bootstrap (cleanup_gnulib): New function. Use it to clean up
10132 gnulib when interrupted. This fixes some race conditions and
10133 works around some portability problems (one noted by Paul

10138 * Makefile.cfg: Adjust to config -> build-aux.
10139 Reported by twledo.

10155 * config/prev-version, config/announce-gen, config/Makefile.am:
10157 * build-aux/prev-version, build-aux/announce-gen,
10158 * build-aux/Makefile.am: here.
10160 2005-10-14 Akim Demaille <akim@epita.fr>
10162 * examples/calc++/test: Use set -x only when VERBOSE.
10164 2005-10-13 Paul Eggert <eggert@cs.ucla.edu>
10166 * NEWS: Bison now warns if it finds a stray `$' or `@' in an action.
10167 * src/scan-gram.l (<SC_BRACED_CODE>[$@]): Implement this.
10169 2005-10-13 Akim Demaille <akim@epita.fr>

10180 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
10181 __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
10182 Problem reported by John P. Hartmann.
10183 * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
10184 already defined it.
10186 2005-10-12 Akim Demaille <akim@epita.fr>

10232 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
10234 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
10236 Undo the parts of the unlocked-I/O change that substituted
10237 putc or puts for printf. This might hurt performance a bit,
10238 but some people prefer the printf style.
10239 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
10240 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

10261 unused-variable warnings.
10263 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

10267 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
10269 Use unlocked I/O for a minor performance improvement on hosts like
10270 GNU/Linux and Solaris that support unlocked I/O. The basic idea
10271 is to use the gnlib unlocked-io module, and to prefer putc and
10272 puts to printf when either will work (since the latter doesn't
10273 come in an unlocked flavor).
10274 * bootstrap (gnulib_modules): Add unlocked-io.
10275 * data/c.m4 (yysymprint): Prefer puts and putc to printf.

10293 * src/system.h: Include unlocked-io.h rather than stdio.h.
10295 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
10296 this confuses xgettext.

10340 * lib/subpipe.c: New function end_of_output_subpipe() added
10341 to allow support for non-posix systems. This is a no-op function
10344 * lib/subpipe.h: New function end_of_output_subpipe() added
10345 to allow support for non-posix systems. This is a no-op function
10348 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
10349 handle the lack of pipe/fork functionality on non-posix systems.
10351 * djgpp/Makefile.maint: DJGPP specific file.
10353 * djgpp/README.in: DJGPP specific file.

10370 * data/lalr1.cc: here.
10371 (location.hh): Include it after the user prologue, in case the
10372 filename type is defined by the user.
10373 Forward declation location and position before the pre-prologue.

10430 2005-09-21 Paul Eggert <eggert@cs.ucla.edu>
10432 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
10433 local variables whose names begin with 'yy'.
10434 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
10435 Trivial changes from Joel E. Denny.
10437 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
10439 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
10440 don't use alloca any more.
10442 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
10443 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
10444 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
10445 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust

10455 This works a bit better with glibc, if user code has already included
10457 * doc/bison.texinfo (Bison Parser): Document that users can't
10458 arbitrarily use malloc and free for other purposes. Document
10459 that <alloca.h> and <malloc.h> might be included.

10474 (yysyntax_error): New function.
10475 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
10476 multiple syntax errors are reported, and alloca is being used.
10477 Instead, reallocate buffers twice as big each time, so that
10478 we waste at most half the allocated memory. Start with a small
10479 (128-byte) buffer that will suffice in most cases anyway.
10480 Use yysyntax_error to do most of the work.
10482 * doc/bison.texinfo (Error Reporting, Table of Symbols):
10483 yynerrs is the number of errors reported, not the number of
10484 errors encountered.

10492 2005-09-19 Akim Demaille <akim@epita.fr>
10494 Remove the traits, failed experiment.
10495 It never proved useful, and anyway because of the current
10496 definition, it was not possible to have several specialization of
10497 this traits, making it useless.
10498 * data/lalr1.cc (yy:traits): Remove.
10499 Inline its definitions in the parser class.
10501 2005-09-19 Akim Demaille <akim@epita.fr>

10508 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
10509 and yytoken for similarity with the other skeletons.
10511 2005-09-19 Akim Demaille <akim@epita.fr>
10513 * NEWS, configure.ac: update version number to 2.1a.

10524 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.

10526 is not defined. This is an awful hack, but it's enough for now.
10527 All callers changed.
10528 * tests/glr-regression-at (make_value): Args are const pointers now,
10529 to avoid GCC warning.
10530 (Duplicated user destructor for lookahead): New test. Currently
10531 skipped. It fails on my host but I'm not sure it'll always fail.
10533 2005-09-16 Akim Demaille <akim@epita.fr>
10535 * src/symtab.h (struct symbol): Declare the printer and destructor
10536 as const, to avoid accidental calls to free.

10545 (b4_token_defines): New, output only the #defines.
10546 * data/yacc.c, data/glr.c: Adjust.
10547 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
10548 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
10551 2005-09-16 Akim Demaille <akim@epita.fr>
10553 * data/lalr1.cc (yylex_): Remove, inline its code.
10554 (yyreport_syntax_error_): Remove, replaced by...
10555 (yysyntax_error_): this which returns a string and leaves to the
10556 caller the call to the users' error function.
10557 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
10558 Move from members of the parser object...
10559 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
10560 to local variables of the parse function.
10562 2005-09-16 Akim Demaille <akim@epita.fr>
10564 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
10565 since it's in Bison's name space.
10567 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
10569 * data/glr.c (yyresolveValue): Add default case to pacify
10570 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
10572 * NEWS: Document when yyparse started to return 2.
10573 * doc/bison.texinfo (Parser Function): Document when yyparse
10576 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
10577 (b4_filename_type): Renamed back from b4_file_name_type. All uses
10579 (class position): file_name -> filename (reverting). All uses changed.
10581 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
10583 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
10584 do anything if $@ exists. This reverts part of the 2005-07-07
10587 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
10589 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
10590 contains obsolete information and isn't worth distributing as a
10591 separate file anyway.
10592 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
10593 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
10594 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
10595 (yyparse): Abort if user code uses longjmp to throw an unexpected
10598 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
10600 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
10601 Suggested by twlevo@xs4all.nl.
10603 * data/glr.c (YYCHK1): Do not assume YYE is in range.
10604 This avoids a diagnostic from gcc -Wswitch-enum.
10605 Problem reported by twlevo@xs4all.nl.
10607 * doc/bison.texinfo: Don't use "filename", as per GNU coding
10608 standards. Use "file name" or "file" or "name", depending on
10610 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
10611 not to hack/foo.tab.c.
10612 (Calc++ Top Level): 2nd arg of main is not const.
10613 * data/glr.c: b4_filename -> b4_file_name.
10614 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
10616 (class position): filename -> file_name. All uses changed.
10617 * data/yacc.c: b4_filename -> b4_file_name.
10618 * lib/bitset.h: filename -> file_name in local vars.
10619 * lib/bitset_stats.c: Likewise.
10620 * src/files.c: Likewise.
10621 * src/scan-skel.l ("@output ".*\n): Likewise.
10622 * src/files.c (file_name_split): Renamed from filename_split.
10623 * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.
10625 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
10627 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
10628 to accommodate latest gnulib.
10630 * tests/glr-regression.at (Duplicate representation of merged trees):
10631 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
10633 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
10636 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
10638 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
10639 All uses changed. Invoke user destructor after an error during a
10640 split parse (trivial change from Joel E. Denny).
10642 * tests/glr-regression.at
10643 (User destructor after an error during a split parse): New test case.
10644 Problem reported by Joel E. Denny in:
10645 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
10647 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
10649 * README-cvs: Give URLs for recommended tools.
10650 Mention Gzip version problem, and bootstrapping issues.
10651 Remove troubleshooting section, as it's somewhat obsolete.
10653 * bootstrap (no_cache): New var, to accommodate different wget
10654 variants. Use it instead of '-C off'. Problem reported by
10657 * data/glr.c (yydestroyStackItem): New function.
10658 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
10659 debugging information. Problem reported by Joel E. Denny.
10661 2005-08-25 Akim Demaille <akim@epita.fr>
10663 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
10665 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
10667 * data/glr.c (yyrecoverSyntaxError, yyreturn):
10668 Don't invoke destructor on unresolved entries.
10669 * tests/glr-regression.at
10670 (User destructor for unresolved GLR semantic value): New test case.
10671 Problem reported by Joel E. Denny in:
10672 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
10674 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
10676 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
10678 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
10679 lib-prefix.m4, po.m4.
10681 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
10682 in yydestruct diagnostic, since it might not be an error.
10683 Problem reported by Joel Denny near end of
10684 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
10685 * data/lalr1.cc (yyerturn): Likewise.
10686 * data/yacc.c (yyreturn): Likewise.
10687 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
10689 * src/files.c: Remove obsolete FIXME comment.
10691 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
10692 with the other templates, and to fix bogus run-on messages such
10693 as the one reported at the end of
10694 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
10695 All callers changed to avoid the newline.
10696 (yyprocessOneStack): Output two lines rather than one, to accommodate
10697 the above change. This changes the debug output format slightly.
10699 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
10700 reported by Joel E. Denny in
10701 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
10703 * tests/glr-regression.at (Duplicate representation of merged trees):
10704 New test, from Joel E. Denny in:
10705 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
10706 * THANKS: Add Joel E. Denny.
10708 * configure.ac (AC_INIT): Bump to 2.0c.
10710 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
10712 * NEWS: Version 2.0b.
10714 * Makefile.am (SUBDIRS): Put examples before tests, so that
10715 "make check" doesn't finish with "All 1 tests passed".
10717 * tests/regression.at (Token definitions): Don't rely on
10718 AT_PARSER_CHECK for data that contains backslashes. It currently
10719 uses 'echo', and 'echo' isn't portable if its argument contains
10720 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
10721 that the byte '\0xff' is not printable in the C locale; it is,
10722 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
10723 not printable, so use '\0x81' to test.
10725 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
10726 version of GCC, since the macro is used with non-GCC compilers.
10728 Fix core dump reported by Pablo De Napoli in
10729 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
10730 * tests/regression.at (Invalid inputs with {}): New test.
10731 * src/parse-gram.y (token_name): Translate type before using
10734 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
10735 the user's name space. All uses changed to __attribute__
10737 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
10738 Add __attribute__ ((__noreturn__)).
10740 * etc/clcommit: Remove. We weren't using it, and it failed
10741 "make maintainer-distcheck".
10742 * Makefile.maint: Merge from coreutils.
10743 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
10744 (syntax-check-rules): Change list of rules as described below.
10745 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
10746 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
10747 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
10748 (sc_trailing_space): New rules.
10749 (sc_xalloc_h_in_src): Remove.
10750 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
10751 (sc_space_tab, sc_error_exit_success, sc_changelog):
10752 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
10753 (makefile-check, po-check, author_mark_check):
10754 (makefile_path_separator_check, copyright-check):
10755 Use grep -n, to make it easier to find violations.
10756 Use CVS_LIST and CVS_LIST_EXCEPT.
10757 (header_regexp, h_re): Remove.
10759 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
10760 (my-distcheck): Use more-modern GCC flags.
10761 (signatures, %.asc): Remove.
10762 (rel-files, announcement): Remove signatures.
10763 Restore old updating code, even though we don't use it, so
10764 that we're the same as coreutils.
10765 (alpha, beta, major): Depend on news-date-check.
10766 Make the upload commands.
10768 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
10769 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
10770 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
10771 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
10772 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
10773 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
10774 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
10775 * tests/sets.at: Likewise.
10777 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
10778 we comment out the Autoconf version number.
10779 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
10780 it's error-prone and "make maintainer-distcheck" rejects it.
10782 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
10783 Indent calls to "error" to pacify "make maintainer-distcheck",
10784 when the calls are not intended to be translated.
10785 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
10787 * src/Makefile.am (DEFS): Use +=, to pacify
10788 "make maintainer-distcheck".
10789 (bison_SOURCES): Add scan-skel.h.
10790 (sc_tight_scope): New rule, from coreutils.
10792 * src/files.c (src_extension, header_extension):
10793 Now static, not extern.
10794 * src/getargs.c (short_options): Likewise.
10795 * src/muscle_tab.c (muscle_table): Likewise.
10796 * src/parse-gram.y (current_class, current_type, current_prec):
10798 * src/reader.c (grammar_end, previous_rule_end): Likewise.
10799 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
10800 * src/main.c (main): Cast bindtextdomain and textdomain calls to
10801 void, to avoid warning when NLS is disabled.
10802 * src/output.c: Include scan-skel.h.
10803 (scan_skel): Remove decl, since scan-skel.h does this.
10805 Indent calls to "error" to pacify "make maintainer-distcheck".
10806 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
10807 * src/reader.h (gram_end, gram_lineno): New decls to pacify
10808 "make maintainer-distcheck".
10809 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
10810 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
10811 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
10812 (skel_lex_destroy, scan_skel): Move these decls to...
10813 * src/scan-skel.h: New file.
10814 * src/uniqstr.c (uniqstr_assert):
10815 Indent calls to "error" to pacify "make maintainer-distcheck".
10817 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
10820 * tests/torture.at: Revamp to avoid misuse of atoi that
10821 "make maintainer-distcheck" complained about.
10823 * examples/extexi (message): Don't print a message more than once,
10824 and omit line-number decoration that makes Emacs compile think
10825 that informative messages are worth worrying about.
10827 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
10829 * configure.ac: Update version number.
10831 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
10833 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
10834 autogenerated by the maintainer.
10835 * examples/calc++/.cvsignore: Add *.yy.
10837 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
10838 * lib/bitset_stats.c (bitset_stats_init): Likewise.
10839 * lib/bitsetv.c (bitsetv_alloc): Likewise.
10841 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
10843 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
10844 from maintainer-distcheck about casting the argument of 'free'.
10846 * NEWS: Mention recent yytname changes.
10847 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
10849 * bootstrap: For translations that have not yet been upgraded to
10850 the new runtime-po domain, prime the pump by extracting the
10851 relevant strings from the obsolete translations. This code can be
10852 removed once the bison-runtime domain has been translated by each
10855 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
10856 now that token names are already quoted.
10858 Fix problem reported by Anthony Heading.
10859 * data/glr.c (YYTOKEN_TABLE): New macro.
10860 (yytname): Define if YYTOKEN_TABLE.
10861 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
10862 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
10863 (YYERROR_VERBOSE): Define the same way the other skeletons do.
10864 * src/output.c (prepare_symbols): Output token_table_flag.
10866 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
10868 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
10869 again if the first call fails.
10871 * data/glr.c (yytnamerr): New function.
10872 (yyreportSyntaxError): Use it to dequote most string literals.
10873 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
10874 with other skeletons. All uses changed.
10875 (yytnameerr_): New function.
10876 (yyreport_syntax_error): Use it to dequote most string literals.
10877 * data/yacc.c (yytnamerr): New function.
10878 (yyerrlab): Use it to decode most string literals.
10879 * doc/bison.texinfo (Decl Summary, Calling Convention):
10880 Clarify quoting convention of yytname.
10881 * src/output.c (prepare_symbols): Quote all names. This undoes
10882 the 2005-04-17 change, which is now accomplished (mostly) via
10883 changes in the parsers as described above.
10884 * tests/regression.at (Token definitions, Web2c Actions):
10885 Undo most 2005-04-17 change here, too.
10887 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
10889 Fix more problems reported by twlevo@xs4all.nl.
10890 * tests/cxx-type.at: Don't pipe output of ./types through sed to
10891 remove trailing spaces. This loses the exit status of ./types,
10892 and isn't needed since ./types shouldn't be emitting trailing
10894 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
10895 as the stack isn't valid in that case.
10897 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
10898 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
10899 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
10900 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
10902 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
10903 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
10904 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
10907 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
10908 overly-picky compilers that reject 'char *foo = "bar";'.
10910 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
10911 to FILE * parameter, not to stderr. This fixes a typo introduced
10912 in the 2005-07-12 change.
10914 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
10915 warnings from GCC 4.
10917 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
10918 (yyglrShiftDefer, yysplitStack):
10919 Remove unused parameters b4_pure_formals. All uses changed.
10920 (yyglrShift): Remove unused parameters b4_user_formals.
10922 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
10924 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
10926 Destructor cleanups and regularization among the three skeletons.
10927 * NEWS: Document the behavior changes.
10928 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
10929 stack before failing, as the cleanup code will do it for us now.
10930 * data/lalr1.cc (yyerrlab): Likewise.
10931 * data/glr.c (yyparse): Pop everything off the stack before
10932 freeing it, so that destructors get called properly.
10933 * data/lalr1.cc (yyreturn): Likewise.
10934 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
10935 This is more consistent.
10936 * doc/bison.texinfo (Destructor Decl): Mention more reasons
10937 why destructors might be called. 1.875 -> 2.1.
10938 (Destructor Decl, Decl Summary, Table of Symbols):
10939 Some English-language cleanups for %destructor.
10940 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10941 Add output line for destructor of start symbol.
10942 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
10943 because of that same extra output line.
10945 * NEWS: Document minor wording changes in diagnostics of
10946 Bison-generated parsers.
10947 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
10948 Remove unused formals. All uses changed.
10949 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
10950 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
10951 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
10952 Rename yyoverflowab to yyexhaustedlab.
10953 When memory exhaustion occurs during syntax-error reporting,
10954 report it separately rather than in a single diagnostic; this
10956 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
10957 (Memory Exhausted): Renamed from Parser Stack Overflow.
10958 Revamp wording slightly to prefer "memory exhaustion".
10959 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
10961 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
10963 Add i18n support to the GLR skeleton. Partially fix the C++
10964 skeleton; a C++ expert needs to finish this. Remove debugging
10965 msgids; there's little point to having them translated, since they
10966 can be understood only by someone who can read the
10967 (English-language) source code.
10969 Generate runtime-po/bison-runtime.pot automatically, so that we
10970 don't have to worry about garbage getting in that file. We'll
10971 make sure after the next official release that old msgids don't
10973 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
10975 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
10976 Now auto-generated.
10977 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
10978 Fix typos in explanations of the runtime file.
10979 * bootstrap: Change gettext keyword from YYI18N to YY_.
10980 Use standard Makefile.in.in in runtime-po, since we'll arrange
10981 for backward-compatible bison-runtime.po files in a different way.
10982 * data/glr.c (YY_): New macro, from yacc.c.
10983 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
10984 Translate messages intended for users.
10985 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
10986 the wording in the other skeletons. We don't know that the memory
10988 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
10989 Use same method that yacc.c uses.
10990 Don't translate debugging messages.
10991 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
10992 it doesn't work (yet), and requires C++ expertise to fix.
10993 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
10994 Move defn to a more logical place, to be consistent with other
10996 Don't translate debugging messages.
10997 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
10998 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
10999 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
11000 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
11002 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
11003 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
11005 * tests/glr-regression.at (Badly Collapsed GLR States):
11007 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
11008 yylex should return 0 at EOF rather than aborting.
11010 Improve tests for stack overflow in GLR parser.
11011 Problem reported by twlevo@xs4all.nl.
11012 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
11014 (yyStackOverflow): Just longjmp, but with value 2 so that caller
11015 can handle the problem.
11016 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
11017 (yyparse): New local variable yyresult to record the result.
11018 Use result of setjmp to set it, rather than storing itinto
11020 (yyDone): Remove label.
11021 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
11022 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
11023 if YYABORT is used).
11024 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
11025 yyparse status; put status > 1 into diagnostic.
11026 Check that status==2 works.
11027 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
11028 Use exit status 3 for failure to open (which shouldn't happen).
11030 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
11032 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
11033 1 on syntax error; just let yyparse do its thing.
11034 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
11035 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
11036 (Exploding the Stack Size with Alloca):
11037 (Exploding the Stack Size with Malloc):
11038 Expect exit status 2, not 1, since the parser is supposed to blow
11039 its stack. Problem reported by twlevo@xs4all.nl.
11041 * data/glr.c (yyparse): Don't assume that the initial calls
11042 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
11043 Print a stack-overflow message and fail instead.
11044 Initialize the line-number information before creating the stack,
11045 so that the stack-overflow message can report line zero safely.
11047 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
11049 Fix problems reported by twlevo@xs4all.nl.
11050 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
11051 (yyuserMerge): Provide a default case if b4_mergers is empty.
11052 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
11053 * tests/glr-regression.at
11054 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
11055 Add casts to pacify C++ compilers.
11056 * tests/glr-regression.at (Improper merging of GLR delayed action
11057 sets): Declare yylex before using it.
11058 * tests/Makefile.am (maintainer-check-g++): Fix a stray
11059 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
11060 test for valgrind; valgrind is independent of g++.
11061 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
11062 for compatibility with POSIX 1003.1-2001 (if running coreutils).
11063 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
11064 Use a destructor, so that we can expand the stack. Change
11065 YYSTYPE to char * so that we can free it. Cast result of malloc.
11067 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11069 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
11070 a valgrind failure. Problem reported by twlevo@xs4all.nl.
11072 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
11074 * PACKAGING: New file, suggested by Bruno Haible and taken from
11075 similar wording in gettext's PACKAGING file.
11076 * NEWS: Mention PACKAGING.
11077 * Makefile.am (EXTRA_DIST): Add PACKAGING.
11079 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
11081 * NEWS: Document recent i18n improvements.
11082 * bootstrap: Get runtime translations into runtime-po.
11083 Create runtime-po files automatically, if possible.
11084 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
11085 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
11086 does not infringe on the user's name space.
11087 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
11088 * doc/bison.texinfo (Internationalization): Revamp the English
11089 and Texinfo syntax a bit, to try to make it clearer.
11090 (Bison Options, Option Cross Key): Mention --print-localedir.
11091 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
11092 YYENABLE_NLS. Quote a bit more.
11093 * runtime-po/.cvsignore: New file.
11094 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
11095 * runtime-po/Rules-quot: Remove; now created by bootstrap.

11099 * runtime-po/en@boldquot.header: Likewise.
11100 * runtime-po/insert-header.sin: Likewise.
11101 * runtime-po/remove-potcdate.sin: Likewise.
11102 * runtime-po/Makevars: Likewise.
11103 * runtime-po/LINGUAS: Likewise.
11104 * runtime-po/de.po: Likewise; we will rely on the translation project
11105 to maintain this, so "bootstrap" should get it.
11106 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
11108 * src/main.c (main): Bind the bison-runtime domain, too.
11110 2005-07-12 Bruno Haible <bruno@clisp.org>
11112 * data/yacc.c: Include <libintl.h> when NLS is enabled.
11113 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
11114 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
11115 * runtime-po: New directory.
11116 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
11117 $(DOMAIN).pot-update rule, so that old messages are never dropped.
11118 * runtime-po/Rules-quot: New file, copied from po/.
11119 * runtime-po/quot.sed: Likewise.
11120 * runtime-po/boldquot.sed: Likewise.
11121 * runtime-po/en@quot.header: Likewise.
11122 * runtime-po/en@boldquot.header: Likewise.
11123 * runtime-po/insert-header.sin: Likewise.
11124 * runtime-po/remove-potcdate.sin: Likewise.

11129 * runtime-po/de.po: New file.
11130 * m4/bison.m4: New file.
11131 * Makefile.am (SUBDIRS): Add runtime-po.
11132 (aclocaldir, aclocal_DATA): New variables.
11133 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
11135 * src/getargs.c (usage): Document --print-localedir option.
11136 (PRINT_LOCALEDIR_OPTION): New enum item.
11137 (long_options): Add --print-localedir option.
11138 (getargs): Handle --print-localedir option.

11140 (Internationalization): New section.
11142 2005-07-12 Akim Demaille <akim@epita.fr>
11144 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
11145 for consistency with the rest of the code.
11146 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
11149 2005-07-12 Akim Demaille <akim@epita.fr>
11151 * src/parse-gram.y: Use %printer instead of YYPRINT.
11153 2005-07-12 Akim Demaille <akim@epita.fr>
11155 * src/symtab.h, src/symtab.c (symbol_print): New.
11156 * src/symlist.h, src/symlist.c (symbol_list_print): New.

11159 2005-07-12 Akim Demaille <akim@epita.fr>
11161 * data/glr.c (b4_syncline): Fix (swap) the definitions of
11162 b4_at_dollar and b4_dollar_dollar.
11164 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
11166 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
11167 and Pennello's paper.
11169 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
11171 * data/yacc.c (yyparse): Undo previous patch. Instead,
11172 set yylsp[0] and yyvsp[0] only if the initial action
11173 sets yylloc and yylval, respectively.
11175 * data/yacc.c (yyparse): In the initial action, set
11176 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
11177 This avoids the use of undefined variables if the initial
11178 action does not set yylloc and/or yylval.
11180 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
11182 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
11183 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
11184 Remove from CVS. These files are automatically generated.
11185 * examples/extexi: Clarify that this file is now part of Bison,
11186 not GNU M4, and that it works with any POSIX-compatible Awk.
11187 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
11188 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
11189 so that we also get calc++-parser.yy. Geneate it.
11190 Use $(AWK), not gawk, since any conforming Awk will do.
11191 Put comment before action, since older 'make' can't handle comment
11193 $(BUILT_SOURCES): List all built sources, not just some of them.
11194 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
11195 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
11196 $($(calc_sources_generated)): Remove unnecessary test for existence
11197 of target. (This had a shell syntax error anyway; a stray "x".)
11198 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
11200 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
11202 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
11203 implied by the other modules.
11205 2005-07-06 Akim Demaille <akim@epita.fr>
11207 Bind examples/calc++ to the package.

11216 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
11218 * data/glr.c (yyFail): Drastically simplify; since the format argument
11219 never had any % directives, we can simply pass it to yyerror.
11220 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
11221 be modified later, as that is the usual style in glr.c.
11222 Problems reported by Paul Hilfinger.
11224 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
11225 and size overflow errors.
11226 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
11227 in case the user prolog sets feature-test macros like _GNU_SOURCE.
11228 (YYSIZEMAX): New macro.
11229 (yystpcpy): New function, taken from yacc.c.
11230 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
11231 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
11232 so that we don't have to maintain their signatures.
11233 (yyFail): Check for buffer overflow, by using vsnprintf rather
11234 than vsprintf. Allocate a bigger buffer if possible.
11235 Report an error if buffer allocation fails.
11236 (yyStackOverflow): New function.
11237 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
11238 the initialization was successful. It might fail if storage was
11240 (yyexpandGLRStack): Add more checks for storage allocation failure.
11241 Use yyStackOverflow to report failures.
11242 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
11243 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
11244 Don't assume stack number fits in int.
11245 (yysplitStack): Check for storage allocation failure.
11246 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
11247 can print diagnostics on storage allocation failure. All callers
11249 (yyresolveValue): Use yybool for boolean.
11250 (yyreportSyntaxError): Check for size-calculation overflow.
11251 This code is taken from yacc.c.
11252 (yyparse): Check for storage allocation errors when allocating
11255 2005-07-05 Akim Demaille <akim@epita.fr>
11257 Extract calc++ from the documentation.
11258 * doc/bison.texinfo (Calc++): Add the extraction marks.
11259 * examples/extexi: New, from the aborted GNU Programming 2E.
11260 Separate the different paragraph of a file with empty lines.
11261 * examples/Makefile: Use it to extract the whole calc++ example.
11263 2005-06-24 Akim Demaille <akim@epita.fr>
11265 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
11268 2005-06-22 Akim Demaille <akim@epita.fr>
11270 * doc/bison.texinfo (C++ Language Interface): First stab.
11271 (C++ Parsers): Remove.
11273 2005-06-22 Akim Demaille <akim@epita.fr>
11275 * data/lalr1.cc (yylex_): Honor %lex-param.
11277 2005-06-22 Akim Demaille <akim@epita.fr>
11279 Start a set of simple examples.
11280 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
11281 * examples/calc++/calc++-driver.hh,
11282 * examples/calc++/calc++-parser.yy,
11283 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
11284 * examples/calc++/compile, examples/calc++/test: New.
11286 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
11288 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
11289 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
11290 which stems from the 2005-05-27 patch.
11292 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
11294 * data/glr.c: Modify treatment of unused parameters to permit use
11295 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
11297 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
11299 Fix infringement on user name space reported by Janos Zoltan Szabo.
11300 * data/yacc.c (yyparse): strlen -> yystrlen.

11304 * data/lalr1.cc (_): New.
11305 Translate the various messages.
11307 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
11309 Fix infringement on user name space reported by Bruno Haible.
11310 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
11311 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
11312 the user's name space.
11313 (alloca): Include <stdlib.h> to get it, if it's not built in.
11314 (YYMALLOC, YYFREE): Define only if needed.
11315 (malloc, free): Declare, but only if needed, as this infringes on
11316 the user name space.
11318 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
11320 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.

11325 * lib/subpipe.c (create_subpipe): Save local variables in case
11326 vfork clobbers them.
11328 2005-05-24 Bruno Haible <bruno@clisp.org>
11330 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
11331 error message syntax used by gcc-4.0.
11333 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
11335 * README: Mention m4 1.4.3. Remove obsolete advice about
11336 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
11338 * bootstrap: Remove workaround for problem I encountered with
11339 gettext 0.14.1; it seems to be fixed now.
11341 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
11343 * NEWS: Version 2.0a.
11345 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
11346 the previous change.
11348 Various maintainer cleanups.
11349 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
11350 conftest*, for benefit of CVS commands run at the same time as
11351 "configure". Add build-aux, since "bootstrap" now creates it and
11353 * Makefile.cfg (move_if_change): Remove.
11354 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
11355 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
11356 (po_repo, do-po-update, po-update, wget_files, get-targets):

11360 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
11362 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
11363 this is now the recommended name.

11365 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
11366 ylwrap. These files now go into build-aux.
11367 * config/move-if-change: Remove.
11368 * config/prev-version.txt: Bump from 1.75 to 2.0.
11370 * bootstrap: Add stdio-safer, unistd-safer modules.

11374 fopen-safer.c, stdio-safer.h, unistd-safer.h.
11375 * lib/subpipe.c: Include "unistd-safer.h".
11376 (create_subpipe): Make sure all the newly-created
11377 file descriptors are > 2, so that diagnostics don't
11378 get sent down them (which might cause Bison to hang, in theory).
11379 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
11380 * src/files.c (xfopen): Use fopen_safer, not fopen.
11382 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
11383 yesterday's yacc.c fix.
11385 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>

11389 Fix a destructor bug reported by Wolfgang Spraul in
11390 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
11391 * data/yacc.c (yyabortlab): Don't call destructor, and
11392 don't set yychar to EMPTY.
11393 (yyoverflowlab): Don't call destructor.
11394 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
11395 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
11396 since we no longer output the message "discarding lookahead token
11399 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11401 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
11402 fix a small glitch in debugging output.
11403 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
11404 after YY_SYMBOL_PRINT where needed.
11406 (struct yyGLRState): Add some comments.
11407 (struct yySemanticOption): Add some comments.
11408 (union yyGLRStackItem): Add comment.
11410 (yymergeOptionSets): Correct this to properly perform the union,
11411 avoiding infinite reported by Michael Rosien.
11414 * tests/glr-regression.at: Add test for GLR merging error reported

11455 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
11457 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
11458 Problem reported by Ralf Menzel.
11460 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
11462 * tests/actions.at: Test that stack overflow invokes destructors.
11463 From Marcus Holland-Moritz.
11464 * data/yacc.c (yyerrlab): Move the code that destroys the stack
11466 (yyreturn): to here. That way, destructors are called properly
11467 even if the stack overflows, or the user calls YYACCEPT or
11468 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
11469 (yyoverflowlab): Destroy the lookahead.
11471 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
11473 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
11475 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
11477 * NEWS: Bison-generated C parsers no longer quote literal strings
11478 associated with tokens.
11479 * src/output.c (prepare_symbols): Don't escape strings,
11480 since users don't want to see C escapes.
11481 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
11483 * tests/input.at (Torturing the Scanner): Likewise.
11484 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
11486 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
11488 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
11489 the data size is known to be too small and we can't increase it.
11490 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
11492 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
11494 * src/parse-gram.y: Include quotearg.h.
11495 (string_as_id): Quote $1 before using it as a key, since the
11496 lexer no longer quotes it for us.
11497 (string_content): Don't strip quotes, since lexer no longer
11499 * src/scan-gram.l: Include quotearg.h.
11500 ("\""): Omit quote.
11501 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
11502 a key, since the rest of the lexer doesn't quote it.
11503 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
11504 * tests/regression.at (Token definitions): Check for backslashes
11507 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
11508 (YYSIZE_T): Define to unsigned long int when using an older compiler.
11509 (yyparse): Revamp code to generate long syntax error message, to
11510 make it easier to translate, and to avoid problems with arithmetic
11511 overflow. Change "virtual memory" to "memory" in diagnostic, since
11512 we don't know whether the memory is virtual.
11514 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
11516 * NEWS: Bison-generated C parsers now use the _ macro to
11518 * data/yacc.c (_) [!defined _]: New macro.
11519 All English strings wrapped inside this macro.
11520 * doc/bison.texinfo (Bison Parser): Document _.
11521 * po/POTFILES.in: Include src/parse-gram.c, since it now
11522 includes translateable strings that parse-gram.y doesn't.
11524 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
11526 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
11527 reverting the 2004-10-11 change to this function.
11528 (symbol_check_alias_consistency): Don't call symbol_type_set
11529 if the type name is already correct.
11530 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
11532 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
11534 * tests/regression.at (Token definitions): Don't use a token named
11535 c, as that generates a "#define c ..." that runs afoul of buggy
11536 stdlib.h that uses the identifier c as a member of struct
11537 drand48_data. Problem reported by Horst Wente.
11539 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
11541 * bootstrap: Change translation URL from
11542 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
11543 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
11544 redirection glitches. Problem reported by twlevo@xs4all.nl.
11546 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
11548 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
11549 after operands; POSIX says this isn't portable for the c99 command.
11551 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
11553 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
11554 immediately if a data overrun has occurred; this may help us track
11555 down what may be a spurious failure on MacOS.
11557 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
11559 Respond to problems reported by twlevo@xs4all.nl.
11561 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
11563 * src/vcg.h: Comment fix.
11564 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
11565 (G_CMAX): Change to -1 instead of INT_MAX.
11567 * data/yacc.c (yyparse): Omit spaces before #line.
11569 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
11571 * src/tables.c (state_number_to_vector_number): Put it inside an
11572 "#if 0", since it's not currently used. Problem reported by
11575 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
11577 * src/output.c (escaped_output): Renamed from
11578 escaped_file_name_output, since we now use it for symbol tags as
11579 well. All uses changed.
11580 (symbol_destructors_output, symbol_printers_output):
11581 Escape symbol tags too.
11582 Problem reported by Matyas Forstner in
11583 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
11585 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
11587 * src/output.c (user_actions_output, token_definitions_output,
11588 symbol_destructors_output, symbol_printers_output): Likewise.
11589 * src/reader.c (prologue_augment): Likewise.
11590 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
11592 * src/vcg.c (output_edge): Don't quote linestyle arg.
11593 Problem reported by twlevo@xs4all.nl.
11595 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
11597 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
11598 example, reported by Derek M Jones. Also, make the example even
11599 more outrageous, to better illustrate how bad the problem is.
11601 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
11603 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
11604 putsym. Typo reported by Sebastian Piping.
11606 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
11608 * doc/bison.texinfo (Language and Grammar): some -> same
11609 (Epilogue): int he -> in the
11610 Typos reported by Sebastian Piping via Justin Pence.
11612 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
11614 * tests/glr-regression.at (Improper handling of embedded actions
11615 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
11616 embedded actions and $-N in GLR parsers", work around an Autoconf bug
11617 with dollar signs in test names.
11618 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
11619 for a similar reason.
11621 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
11623 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
11624 wants to redefine G_VIEW.
11626 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
11628 * src/vcg.c (get_view_str): Remove case for normal_view.
11629 Problem reported by twlevo@xs4all.nl.
11631 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
11633 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
11634 Problem reported by twlevo@xs4all.nl.
11636 * doc/bison.texinfo: Change @dircategory from "GNU programming
11637 tools" to "Software development". Requested by Richard Stallman
11640 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
11642 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
11643 Problem reported by twlevo@xs4all.nl.
11645 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
11647 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
11648 keyword; it's not needed with modern compilers, and it doesn't
11649 affect correctness with older compilers. Suggested by
11652 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
11654 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
11655 gcc -Wswitch-default.
11656 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
11657 * data/yacc.c (yyparse): Likewise.
11659 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
11661 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
11662 already. Let config.h define any nonstandard values.
11664 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
11666 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
11667 for the benefit of slower hosts. Problem reported by
11668 Nelson H. F. Beebe.
11670 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
11672 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
11673 being defined and not used.
11674 * data/lalr1.cc (yyparse): Likewise.
11675 Use "if (false)" rather than "if (0)".
11677 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
11679 * TODO: Mention that we should allow NUL bytes in tokens.
11681 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
11683 * src/scan-skel.l (<<EOF>>): Don't close standard output.
11684 Problem reported by Hans Aberg.
11686 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
11688 * src/getargs.c (version): Happy new year; update overall
11689 program copyright date from 2004 to 2005.
11691 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
11692 Problem reported by Hans Aberg.
11693 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
11694 (Output file names.): Add a test for the case when standard output
11697 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
11699 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
11700 to fix an oversight in the Bison 2.0 manual.
11702 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
11704 * NEWS: Version 2.0. Reformat the existing news items since
11705 1.875, so that related items are grouped together.
11706 * configure.ac (AC_INIT): Bump version to 2.0.
11707 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
11709 * tests/torture.at (Exploding the Stack Size with Alloca): Set
11710 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
11711 otherwise, we're not testing alloca. Unfortunately there's no
11712 simple way to consult HAVE_ALLOCA here.
11714 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
11717 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
11718 hand. This avoids a warning about comparing int to size_t when
11719 GCC warnings are enabled.
11721 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
11723 * NEWS: Bison-generated parsers no longer default to using the
11724 alloca function (when available) to extend the parser stack, due
11725 to widespread problems in unchecked stack-overflow detection.
11726 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
11727 responsibility to set it to a positive value. This lets the user
11728 specify a value that is not a preprocessor constant.
11729 * data/yacc.c (YYMAXDEPTH): Likewise.
11730 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
11731 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
11732 to be a compile-time constant. However, explain the constraints on it.
11733 Also, explain the constraints on YYINITDEPTH.
11734 (Table of Symbols): Explain that alloca is no longer the default.
11735 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
11738 * doc/bison.texinfo (Location Default Action): Mention that n must
11739 be zero when k is zero. Suggested by Frank Heckenbach.
11741 2004-12-22 Akim Demaille <akim@epita.fr>
11743 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
11744 (parser::state_type, parser::semantic_type, parser::location_type):
11745 Private, not public.
11746 (parser::parse): Return ints, not bool.
11747 Returning a bool introduces a problem: 0 corresponds to false, and
11748 it seems weird to return false on success. Returning true changes
11749 the conventions for yyparse.
11750 Alternatively we could return void and send an exception.
11751 There is no clear consensus (yet?).
11752 (state_stack, semantic_stack, location_stack): Rename as...
11753 (state_stack_type, semantic_stack_type, location_stack_type): these.
11754 Private, not public.
11755 * tests/c++.at: New.
11756 * tests/testsuite.at, tests/Makefile.am: Adjust.
11758 2004-12-21 Akim Demaille <akim@epita.fr>
11760 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
11762 2004-12-21 Akim Demaille <akim@epita.fr>
11764 Don't impose std::string for filenames.
11766 * data/lalr1.cc (b4_filename_type): New.
11767 (position::filename): Use it.
11768 (parser.hh): Move the inclusion of stack.hh and location.hh below
11769 the user code, so that needed headers for the filename type can be
11771 Forward declare them before the user code.
11772 * tests/Makefile.am (check-local, installcheck-local): Pass
11773 TESTSUITEFLAGS to the TESTSUITE.
11775 2004-12-20 Akim Demaille <akim@epita.fr>
11777 Use more STL like names: my_class instead of MyClass.
11779 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
11780 (SemanticStack, SemanticType, StateStack, StateType)
11781 (TokenNumberType, Stack, Slice, Traits, Parser::location)
11782 (Parser::value): Rename as...
11783 (location_stack, location_type, rhs_number_type, semantic_stack)
11784 (semantic_type, state_stack, state_type, token_number_type, stack)
11785 (slice, traits, parser::yylloc, parser::yylval): these.
11787 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
11789 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
11791 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
11792 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
11794 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
11796 Remove uses of 'short int' and 'unsigned short int'. This raises
11797 some arbitrary limits. It uses more memory but nowadays that's
11798 not much of an issue.
11800 This change does not affect the generated parsers; that's a different
11801 task, as some users will want to conserve memory there.
11803 Ideally we should use size_t to represent all object counts, and
11804 something like ptrdiff_t to represent signed differences of object
11805 counts; but that will require more code-cleanup than I have the
11806 time to do right now.
11808 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
11809 Use size_t, not int or short int, to count objects.
11810 * src/closure.c (nritemset, closure): Likewise.
11811 * src/closure.h (nritemset, closure): Likewise.
11812 * src/nullable.c (nullable_compute): Likewise.
11813 * src/print.c (print_core): Likewise.
11814 * src/print_graph.c (print_core): Likewise.
11815 * src/state.c (state_compare, state_hash): Likewise.
11816 * src/state.h (struct state): Likewise.
11817 * src/tables.c (default_goto, goto_actions): Likewise.
11819 * src/gram.h (rule_number, rule): Use int, not short int.
11820 * src/output.c (prepare_rules): Likewise.
11821 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
11822 errs, reductions): Likewise.
11823 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
11825 * src/tables.c (vector_number, tally, action_number,
11826 ACTION_NUMBER_MINIMUM): Likewise.
11827 * src/output.c (muscle_insert_short_int_table): Remove.
11829 2004-12-17 Akim Demaille <akim@epita.fr>
11831 * data/lalr1.cc: Extensive Doxygenation.
11832 (error_): Rename as...
11833 (error): this, since it is visible to the user.
11835 (Parser::message): Now an automatic variable from...
11836 (Parser::yyreport_syntax_error_): here.
11837 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
11839 * tests/input.at: Escape $.
11841 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
11843 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
11844 Parenthesize rhs to avoid obscure problems with mistakes like

11846 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
11847 b4_rhs_location): Likewise.
11848 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
11849 b4_rhs_location): Likewise.
11851 2004-12-16 Akim Demaille <akim@epita.fr>
11853 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
11854 yacc.c: be sure to stay within yycheck_.
11855 * tests/actions.at: Re-enable C++ tests.
11857 2004-12-16 Akim Demaille <akim@epita.fr>
11859 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
11862 2004-12-16 Akim Demaille <akim@epita.fr>
11864 Use #define to handle the %name-prefix.
11866 * data/glr.c, data/yacc.c: Comment changes.
11867 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
11868 so that one can refer to yylex in the parser file, and have it
11869 renamed, as is the case with other skeletons.
11871 2004-12-16 Akim Demaille <akim@epita.fr>
11873 Move lalr1.cc internals into yy*.

11893 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
11895 Fix some problems reported by twlevo at xs4all.
11896 * src/symtab.c (symbol_new): Report an error if the input grammar
11897 contains too many symbols. This is better than calling abort() later.
11898 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
11899 (struct node, struct graph):
11900 Rename member expand to stretch. All uses changed.
11901 (struct graph): Remove member layoutalgorithm. All uses removed.
11902 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
11903 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
11905 (N_STRETCH): Rename from N_EXPAND. All uses changed.
11907 2004-12-15 Akim Demaille <akim@epita.fr>
11909 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
11910 Add more Doxygen comments.
11911 (symprint_, stack_print_, reduce_print_, destruct_, pop)
11912 (report_syntax_error_, translate_): Rename as...
11913 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
11914 (yypop_, yyreport_syntax_error_, yytranslate_): this.
11916 2004-12-15 Akim Demaille <akim@epita.fr>
11918 * data/lalr1.cc (lex_): Rename as...
11920 Move the trace here.
11921 Take the %name-prefix into account.
11922 Reported by Alexandre Duret-Lutz.
11924 2004-12-15 Akim Demaille <akim@epita.fr>
11926 Simplify the C++ parser constructor.
11928 * data/lalr1.cc (debug_): Rename as...
11929 (yydebug_): so that the parser's internals are always in the yy*
11932 (b4_parse_param_decl): Remove the leading comma as it is now only
11933 called as unique argument list.
11934 (Parser::Parser): Remove the constructor accepting a location and
11935 an initial debugging level.
11936 Remove from the other ctor the argument for the debugging level.
11937 (debug_level_type, debug_level, set_debug_level): New.
11939 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
11942 2004-12-15 Akim Demaille <akim@epita.fr>
11944 Remove b4_root related material: failure experiment
11945 (which goal was to allow to derive from a class).
11947 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
11948 definitions and uses.
11950 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
11952 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
11953 not 2, since it's not portable to subtract 1 from the start of an
11954 array. The new item 0 is never set or used. All uses changed.
11956 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
11957 the default definition of YYLLOC_DEFAULT. Problem reported
11958 by Frank Heckenbach.
11960 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
11962 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
11963 the normal case and one for the error case. Just use the
11964 first one uniformly. Problem reported by Frank Heckenbach.
11965 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
11966 use exactly the same macro in both places.
11967 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
11968 so that the normal-case YYRHSLOC works for the error case too.
11970 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
11971 (YYLLOC_DEFAULT): Use the same macro as glr.c.
11972 * doc/bison.texinfo (Location Default Action): Don't claim that
11973 we have an array of locations. Use the same macro for both glr
11974 and lalr parsers. Mention YYRHSLOC. Mention what happens when
11977 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
11979 * HACKING: Update email addresses to send announcements to.
11981 * configure.ac (AC_INIT): Bump version to 1.875f.
11983 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
11985 * NEWS: Version 1.875e.
11986 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
11988 * src/scan-skel.l: Include "complain.h", for "fatal".
11990 * src/relation.h (relation_print, relation_digraph):
11991 Relation sizes are of type relation_node, not size_t (this is
11992 merely a doc fix, since the two types are equivalent).
11993 (relation_transpose): Relation sizes are of type relation_node,
11995 * src/relation.c: Likewise.
11996 (top, infinity): Now of type relation_node, not int.
11997 (traverse, relation_transpose): Use relation_node, not int.
11999 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
12000 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
12001 (yyparse): Remove unused local introduced in 2004-10-25 patch.
12003 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
12004 specifying whether the test should be skipped. Use it tp
12005 specify that the [%defines %skeleton "lalr1.cc"] tests currently
12006 fail on some hosts, and should be skipped.
12008 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
12010 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
12011 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
12012 unless otherwise specified below.
12014 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
12015 to allocate kernel_base, kernel_items, kernel_size, since
12016 they needn't be initialized to 0.
12017 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
12018 * src/closure.c (new_closure): Likewise, for itemset.

12027 (relation_transpose): Likewise for new_R, end_R.
12028 * src/symtab.c (symbols_token_translations_init): Likewise for
12029 token_translations.
12030 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
12031 (token_actions): Likewise for yydefact, actrow, conflrow,
12033 (save_column): Likewise for froms[symno], tos[symno].
12034 (goto_actions): Likewise for state_count.
12035 (pack_table): Likewise for base, pos, check.
12036 (tables_generate): Likewise for width.
12038 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
12039 for initial core. Just have a separate core, so we needn't worry
12040 about whether kernel_size and kernel_base are initialized.
12042 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
12043 kernel_size, kernel_items): Remove unnecessary initialization.
12044 * src/conflicts.c (conflicts): Likewise.
12045 * src/derives.c (derives): Likewise.
12046 * src/muscle_tablc (muscle_insert): Likewise.

12048 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
12049 conflrow, conflict_table, conflict_list, table, check):
12052 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
12053 This is because all callers pass unsigned int.
12054 * src/closure.h (new_closure): Likewise.
12056 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
12057 (build_relations): Initialize includes[i] in all cases.
12058 * src/reader.c (packgram): Always initialize rules[ruleno].prec
12059 and rules[ruleno].precsym. Initialize members in order.
12060 * src/relation.c (relation_transpose): Always initialize new_R[i]
12062 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
12064 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
12065 conflict_list[0] was always 0, but now it isn't initialized.
12067 * src/table.c (table_grow): When conflict_table grew, the grown
12068 area wasn't cleared. Fix this.
12070 * lib/.cvsignore: Add strdup.c, strdup.h.
12071 * m4/.cvsignore: Add strdup.m4.
12073 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
12075 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
12076 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
12077 GOTO_NUMBER_MAXIMUM, since we occasionally compute
12078 ngotos + 1 without checking for overflow.
12079 (build_relations): Use END_NODE, not -1, to denote end of edges.
12080 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
12081 build_relations): Use goto_number, not int, for goto numbers.
12082 * src/tables.c (save_column, default_goto): Likewise.
12084 2004-11-23 Akim Demaille <akim@epita.fr>
12086 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
12087 of #defining from yystype.
12088 Don't typedef yystype, C++ does not need it.
12089 This lets it possible to forward declare it as union.
12091 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
12093 * bootstrap (gnulib_modules): Add extensions.
12094 Problem reported by Jim Meyering.
12096 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
12098 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
12099 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
12100 src/system.h, src/tables.c: XFREE -> free, to accommodate
12101 recent change to gnulib xalloc.h.
12102 Problem reported by Jim Meyering.
12104 2004-11-17 Akim Demaille <akim@epita.fr>
12106 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
12108 2004-11-17 Akim Demaille <akim@epita.fr>,
12109 Alexandre Duret-Lutz <adl@gnu.org>
12111 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
12113 (YYCDEBUG): Adjust.
12114 Use it instead of cdebug_.
12115 (Parser::debug_stream, Parser::set_debug_stream): New.
12116 (Parser::symprint_): Define cdebug_ for temporary backward
12118 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
12121 2004-11-17 Akim Demaille <akim@epita.fr>
12123 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
12124 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
12125 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
12126 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
12128 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
12130 * data/glr.c (yyloc_default): Remove; not used.
12131 Problem reported by Frank Heckenbach.
12133 2004-10-25 Akim Demaille <akim@epita.fr>
12135 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
12136 Introduce another definition to address simple location arrays.
12137 (yyGLRStack): New member: yyerror_range.
12138 (yyrecoverSyntaxError, yyparse): Update it.
12139 (yyrecoverSyntaxError): Use it when shifting the error token to
12140 have an accurate range, equivalent to the one computed by both
12141 yacc.c and lalr1.cc.
12142 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
12143 that column numbers start at column 0, as per GNU Coding
12144 Standards, the others tests, and the doc.
12145 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
12146 Adjust to the above change (first column is 0).
12147 And adjust the location of the "<error>", now covering the whole
12150 2004-10-22 Akim Demaille <akim@epita.fr>
12151 and Paul Eggert <eggert@cs.ucla.edu>
12153 Remove some arbitrary limits on goto numbers and relations.
12154 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
12155 initial values, since they're never used.
12156 (set_goto_map): ngotos is now unsigned, so test for overflow
12157 by seeing whether it wraps around to zero.
12158 * src/lalr.h (goto_number): Now size_t, not short int.
12159 (GOTO_NUMBER_MAXIMUM): Remove.
12160 * src/relation.c (relation_print, traverse, relation_transpose):
12161 Check for END_NODE rather than looking at sign.
12162 * src/relation.h (END_NODE): New macro.
12163 (relation_node): Now size_t, not short int.
12165 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
12167 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
12168 keyword, not an identifier. Problem reported by Baron Schwartz in
12169 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
12171 2004-10-11 Akim Demaille <akim@epita.fr>
12173 * src/symtab.c (symbol_check_alias_consistency): Also check
12174 type names, destructors, and printers.
12175 Reported by Alexandre Duret-Lutz.
12176 Recode the handling of associativity and precedence in terms
12177 of symbol_precedence_set.
12178 Accept no redeclaration at all, not even equal to the previous
12180 (redeclaration): New.
12181 Use it to factor redeclaration complaints.
12182 (symbol_make_alias): Don't set the type of the alias, let
12183 symbol_check_alias_consistency do it as for other features.
12184 * src/symtab.h (symbol): Add new member prec_location, and
12186 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
12187 * tests/input.at (Incompatible Aliases): New.
12189 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
12191 .cvsignore fixes to accommodate gnulib changes,
12192 and the practice of naming build directories "_build".
12193 * .cvsignore: Add "_*". Sort.
12194 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
12195 * m4/.cvsignore: Add "*_gl.m4".
12197 2004-10-06 Akim Demaille <akim@epita.fr>
12199 * src/parse-gram.y (add_param): Fix the truncation of trailing
12202 2004-10-05 Akim Demaille <akim@epita.fr>
12204 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
12205 whether the reducion was empty or not. This leaves room to
12206 improve the use of YYLLOC_DEFAULT in such a case.
12207 lalr1.cc is still experimental, so changing this is acceptable.
12208 And finally, there are probably not many users who changed the
12209 handling of locations in GLR, so changing is admissible too.
12211 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
12212 empty reduction, set @$ to an empty location ending the previously
12214 Adjust uses to make sure the code is triggered on empty
12216 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
12217 expected output: empty reductions have empty locations.
12219 2004-09-29 Akim Demaille <akim@epita.fr>
12221 * data/lalr1.cc: Move towards a more standard C++ coding style
12222 for templates: Class < T > -> Class<T>.
12224 2004-09-29 Akim Demaille <akim@epita.fr>
12226 * data/lalr1.cc: Reinstall the former ctor, for sake of
12227 compatibility, but warn it will be removed.
12228 Move towards a more standard C++ coding style (i.e., type *var ->
12231 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
12233 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
12234 since it's less likely to work if NULs are involved in the future.
12236 2004-09-27 Akim Demaille <akim@epita.fr>
12238 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
12240 2004-09-27 Akim Demaille <akim@epita.fr>
12242 * data/lalr1.cc (b4_parse_param_decl_1): New.
12243 (b4_parse_param_decl): Use it to have different names between attribute
12244 and argument names.
12245 (b4_cc_constructor_call): Likewise.
12247 2004-09-24 Akim Demaille <akim@epita.fr>
12249 * src/parse-gram.y (add_param): Strip the leading and trailing
12250 blanks from a formal argument declaration.
12251 (YY_LOCATION_PRINT): New.
12253 2004-09-24 Akim Demaille <akim@epita.fr>
12255 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
12256 after the location.
12258 2004-09-24 Akim Demaille <akim@epita.fr>
12260 * doc/bison.texinfo (Table of Symbols): Sort.
12262 2004-09-21 Akim Demaille <akim@epita.fr>
12264 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
12265 the useless parentheses.
12266 Suggested by Paul Eggert.
12268 2004-09-20 Akim Demaille <akim@epita.fr>
12270 Let the initial-action act on the look-ahead, and use it for the
12271 "initial push" (corresponding to an hypothetical beginning-of-file).
12272 And let lalr1.cc honor %initial-action.
12274 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
12276 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
12277 (Parser::Parser): Remove the ctor that used to initialize it.
12278 (Parser::parse): Like in the other skeletons, issue the "starting
12279 parse" message before any action.
12280 Honor %initial-action.
12281 Initialize the stacks with the lookahead.
12282 * data/yacc.c: Let $$ and @$ in %initial-action designate the
12284 Push them in the stacks.
12285 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
12287 2004-09-20 Akim Demaille <akim@epita.fr>
12289 * doc/bison.texinfo (Initial Action Decl): New.
12291 2004-09-20 Akim Demaille <akim@epita.fr>
12293 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
12294 clearer criterion to define it.
12295 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
12296 When reducing on an empty RHS, use the latest stacked location as
12298 yylloc is not always available.
12299 * data/glr.c: Likewise.
12300 Also, honor initial-actions.
12302 2004-09-20 Akim Demaille <akim@epita.fr>
12304 * data/yacc.c (YY_LOCATION_PRINT): New.
12305 Define when we know YYLTYPE's structure, i.e., when the default
12306 YYLLOC_DEFAULT is used.
12307 * data/c.m4 (b4_yysymprint_generate): Use it.
12308 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
12309 value of the result.
12310 (error_start_): Replace with...
12311 (error_range_): this location array.
12312 This allows to replace code relying on the implementation of
12313 locations by portable code.
12314 * data/yacc.c (yylerrsp): Replace with...
12315 (yyerror_range): this.
12316 Every time a token is popped, update yyerror_range[0], to have an
12317 accurate location for the error token.
12318 * data/glr.c (YY_LOCATION_PRINT): New.
12319 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
12320 deference a pointer.
12321 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
12322 report the location in %printers.
12324 * src/scan-skel.l: Instead of abort, report error messages to ease
12325 understanding skeleton scanning failures.
12327 2004-09-16 Akim Demaille <akim@epita.fr>
12329 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
12330 (iterator, const_iterator): these, to be more in the C++ spirit.
12331 Also, return reverse iterators so that when displaying the stack
12332 we display its bottom first.
12333 (Parser::stack_print_, Parser::reduce_print_): Match the messages
12335 We should probably use vector here though.
12337 2004-09-16 Akim Demaille <akim@epita.fr>
12339 Have more complete shift traces.
12341 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
12342 to report Shifts instead of ad hoc YYDPRINTF invocations,
12343 including for the error token.
12344 * data/lalr1.cc (symprint_): Output the location.
12345 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
12346 output the location within the %printer.
12347 Activate GLR tests, at least to make sure they compile properly.
12348 They still don't pass though.
12349 * tests/calc.at: Adjust expect verbose output, since now "Entering
12350 state..." is on a different line than the "Shifting" message.
12352 2004-09-08 Akim Demaille <akim@epita.fr>
12354 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
12355 Bison directive from the Bison file to the invocation of this
12356 macro, so that these directives are passed to
12357 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
12358 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
12359 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
12360 the extra Bison directives instead of the whole series.
12361 Change the grammar so that there are recoverable errors, and
12362 unrecoverable errors. Now we can have the parser give up before
12363 consuming the whole input. As a result we now can observe that
12364 the lookahead is freed when needed.
12365 Change the parser source to parse argv[1] instead of a hard coded
12367 Simplify yylex, and give a value and location to EOF.
12368 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
12369 passed directives already coded in the file.
12370 Add some tests to check the location of "error".
12371 For some tests, the C++ parser is correct, and not yacc.c.
12372 For other tests, they provide different, but unsatisfying, values,
12373 so keep the C++ value so that at least one parser is "correct"
12374 according to the test suite.
12375 (Actions after errors): Remove, this is subsumed by the
12376 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
12378 2004-09-06 Akim Demaille <akim@epita.fr>
12380 * data/lalr1.cc: Adjust the indentation of the labels.
12381 (Parser::pop): New.
12384 2004-09-06 Akim Demaille <akim@epita.fr>
12386 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
12387 argument, an informative message.
12388 Call YY_SYMBOL_PRINT.
12389 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
12390 * data/lalr1.cc (destruct_): Likewise.
12391 In addition, no longer depend on b4_yysymprint_generate and
12392 b4_yydestruct_generate to generate these functions, do it "by
12395 2004-09-03 Akim Demaille <akim@epita.fr>
12397 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
12398 invoked, yydestruct the lookahead.
12399 * tests/calc.at (Calculator $1): Update the expected lengths of
12400 traces: there is an added line for the discarded lookahead.
12401 * doc/bison.texinfo (Destructor Decl): Some rewording.
12402 Define "discarded" symbols.
12404 2004-09-02 Akim Demaille <akim@epita.fr>
12406 * data/lalr1.cc (translate_, destruct_): No reason to be static.
12408 2004-09-02 Akim Demaille <akim@epita.fr>
12410 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
12411 (YYDSYMPRINTF): Rename as...
12412 (YY_SYMBOL_PRINT): this.
12413 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
12415 Use it instead of direct symprint_ calls.
12416 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
12419 2004-09-02 Akim Demaille <akim@epita.fr>
12421 * data/lalr1.cc (b4_yysymprint_generate): New.
12422 (symprint_): New member function, defined when YYDEBUG.
12423 Use it consistently instead of token/nterm debugging output by
12425 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
12426 %printer calls to use cdebug_ when using lalr1.cc.
12428 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
12430 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
12431 with #ifdef YYDEBUG.
12433 2004-08-26 Akim Demaille <akim@epita.fr>
12435 * doc/bison.texinfo (Implementing Loops): Rename as...
12436 (Implementing Gotos/Loops): this.
12438 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
12440 Adjust to latest gnulib.
12441 * bootstrap (gnulib_modules): Add xalloc-die.
12442 Set LC_ALL=C so that file names sort consistently.
12443 Prefer the gnulib copies of gettext.m4, glibc21.m4,
12444 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
12445 uintmax_t.m4, ulonglong.m4.
12446 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
12447 po.m4 since we are now using _gl.m4 instead.
12449 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
12451 * src/scan-action.l: Remove. Scanning of semantic actions is
12452 handled in scan-gram.l.
12454 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
12456 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
12458 * src/location.h (struct): The file member is a uniqstr.
12459 (equal_boundaries): Use UNIQSTR_EQ for comparison.
12461 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
12463 Fix bug with non-%union parsers that have printers or destructors,
12464 which led to a Bison core dump. Reported by Peter Fales in
12465 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
12467 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
12468 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
12469 not to our own type.
12470 * src/output.c (symbol_destructors_output, symbol_printers_output):
12471 Don't assume %union.
12472 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
12473 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
12474 UNION-FLAG. All callers changed.
12475 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
12476 Use type char, not unsigned int, when declaring an array of char;
12477 this lets us remove a cast.
12478 (Printers and Destructors): Add non-%union test cases.
12480 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
12482 * doc/bison.texinfo: Minor editorial changes, mostly to the new
12483 GLR writeups. E.g., avoid frenchspacing and the future tense,
12484 change "lookahead" to "look-ahead", and change "wrt" to "with
12487 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
12489 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
12490 New sections, split off from the GLR Parsers section. Put the new
12491 Simple GLR Parser near the start of the GLR section, for clarity.
12492 Rewrite connective text.
12494 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
12496 * doc/bison.texinfo (Simple GLR Parsers): New section.
12498 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
12500 * NEWS, TODO, doc/bison.texinfo:

12532 * tests/atlocal.in (CXXFLAGS): Use it.
12534 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
12536 Fix some "make check" problems with C++ reported by
12537 Albert Chin-A-Young for Tru64 C++ in this thread:

12550 C++ compiler. (trivial change)
12552 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
12554 Spent a few hours checking out which prerequisite versions the
12555 current sources actually require. I went all the way back to
12556 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
12557 a seemingly endless set of combinations of versions more recent
12558 than that. The bottom line is that the current sources require
12559 fairly recent versions of the build tools, and it'll be some work
12561 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
12562 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
12563 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
12564 Add comments explaining why those particular versions are
12567 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
12568 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
12569 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
12571 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
12572 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
12574 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
12576 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
12577 0.11.5. Suggested by Bruno Haible.
12578 * bootstrap: Remove gettext version checking.
12580 * doc/bison.texinfo (Decl Summary): Also mention that %union
12581 can depend on prerequisite types. Problem reported by Tim
12584 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
12586 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
12587 * README-alpha: Don't tell people not to package this.
12589 * bootstrap: Don't assume $(...) works; use `...` instead.
12590 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
12593 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
12594 put into the -d output file, and mention what to do if YYSTYPE is
12595 defined as a macro.
12597 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
12599 Undo change made earlier today: it caused autopoint to not bring
12600 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
12603 * bootstrap: Check that gettext version matches what's in
12604 configure.ac. Warn users to ignore robots.txt ERROR 404.
12605 * bootstrap: Undo today's earlier change (logged below).
12606 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
12608 The gettext version checking is causing more trouble than it's
12609 curing; remove it. Problem reported by Paul Hilfinger.
12611 * bootstrap: Issue a warning that one can expect a message
12612 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
12613 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
12615 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
12617 Ensure that the C++ compiler used for testing actually works on a
12618 simple test program; if not, skip the C++-related tests. Problem
12619 reported by Vin Shelton in:
12620 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
12622 * m4/cxx.m4: New file.

12627 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
12629 * data/glr.c (yylloc): Output this macro even if locations are not
12630 being generated, as the GLR parser needs it even in that case.
12631 Problem reported by Troy A. Johnson
12632 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
12634 * configure.ac (AC_INIT): Update to 1.875e.

12638 * NEWS: Version 1.875d.
12639 * configure.ac (AC_INIT): Likewise.
12640 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
12642 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
12643 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
12644 lalr1.cc runs afoul of the first, and the last two are no longer
12645 supported by GCC 3.4.0.
12646 * README: Mention GNU m4 1.4 or later; mention m4 patches.
12647 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
12649 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
12651 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
12652 unsigned int, for compatibility with latest gnulib hash module.
12653 * src/state.c (state_hash, state_hasher): Likewise.
12654 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.

12661 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
12662 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
12663 character and string literals.
12664 (unexpected_end): New function.
12665 (unexpected_eof): Use it.
12666 (unexpected_newline): New function.
12667 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
12670 * NEWS: Document %expect-rr.
12672 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
12673 Fix typo by replacing $1 with $option.
12674 Remove more 'intl'-related files.
12675 Don't DEFUN AM_INTL_SUBDIR twice.
12677 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
12678 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
12680 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
12681 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
12682 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,

12684 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
12685 * src/.cvsignore: Add *.output.
12687 * src/parse-gram.y: Put copyright notice inside %{ %} so it
12688 gets copied to the output file.
12690 2004-04-28 Paul Eggert <eggert@twinsun.com>
12692 Get files from the gnulib and po repositories, instead of relying
12693 on them being in our CVS. Upgrade to latest versions of gnulib
12696 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
12697 * bootstrap: Bootstrap from gnulib and po repositories.
12698 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
12699 * README-cvs: Document these changes. Remove version numbers from
12700 mentions of build tools, since they change so often. Mention Flex.
12702 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
12703 (gl_USE_SYSTEM_EXTENSIONS): Add.
12704 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
12705 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
12707 (AC_ISC_POSIX): Remove; we no longer support this
12708 ancient OS, as it gets in the way of latest Autoconf & gnulib.
12709 (AC_HEADER_STDC): Remove: we now assume C89 or better.
12710 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
12711 Do not check for C89 headers, except for locale.h which is used
12712 by the Yacc library and must port to K&R hosts.
12713 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
12714 Do not check for C89 functions, except for setlocale which is
12715 used by the Yacc library.
12716 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
12717 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

12720 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
12721 AM_GNU_GETTEXT): Remove; now done by:
12722 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
12723 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
12726 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
12727 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
12728 Define to empty, as gnulib.mk will do the rest for us.
12729 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
12731 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
12732 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
12734 * src/files.c: Include gnulib's xstrndup.h.
12736 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
12737 (REALLOC): Use xnrealloc, for likewise.
12738 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
12739 (strnlen, memrchr): Remove decls; functions no longer used.
12740 Include <stpcpy.h>.

12763 Remove, as these files are now generated automatically
12764 by bootstrap or automake.
12766 * po/ChangeLog: Remove: all but one entry was a duplicate
12767 of this file, and I moved that 2000-11-02 entry here.
12769 * config/.cvsignore: Add Makefile, depcomp, install-sh.
12770 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

12785 * po/.cvsignore: Add *.po, LINGUAS, Makefile.in.in, Makevars.
12786 * src/.cvsignore: Remove *_.c.
12789 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
12790 support it. (The latest stable gzip doesn't.)
12792 2004-04-27 Paul Eggert <eggert@twinsun.com>
12794 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
12795 case, as stos_ is now used by destructors due to the 2004-02-09
12798 Remove more K&R C support.
12799 * lib/libiberty.y (PARAMS): Remove. All uses removed.
12800 * lib/subpipe.c (errno): Remove decl.
12801 Include <stdlib.h> unconditionally.
12802 (EXIT_FAILURE): Remove macro.
12803 * src/complain.c (vfprintf, strerror): Remove.
12804 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
12806 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
12807 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
12808 (strchr, strspn, memchr): Remove decls.
12809 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
12810 unconditionally. Do not declare perror.
12811 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
12814 * src/complain.c (_): Remove useless defn, as system.h defines this.
12816 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
12817 with latest obstack.h.
12818 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
12819 to procedure types, as obstack.h now does that for us.
12820 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
12822 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
12823 so that this include file can stand alone.
12824 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
12825 does this now. Include subpipe.h first after config.h, to
12826 test whether it can stand alone.
12828 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
12829 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
12830 unused declaration.
12832 * tests/synclines.at (%union synch line): Put a dummy member in
12833 the union, because empty unions aren't allowed in C. Caught
12836 2004-04-13 Jim Meyering <jim@meyering.net>
12838 * src/conflicts.c (conflicts_print): Correct format string typo:
12839 use `%%' to produce literal `%'. (trivial change)
12841 2004-03-30 Paul Eggert <eggert@twinsun.com>
12843 * src/getargs.c (version): Update copyright year to 2004.
12845 * data/c.m4 (b4_int_type): Use 'short int' rather than
12846 'short', and similarly for 'long', 'unsigned', etc.

12885 (declaration): Replace expected_conflicts with expected_sr_conflicts.
12886 Add %expect-rr rule.
12888 * src/scan-gram.l: Recognize %expect-rr.

12891 expected_conflicts.
12892 (expected_rr_conflicts): Declare.
12894 * src/conflicts.c (expected_sr_conflicts): Rename from
12895 expected_conflicts.
12896 (expected_rr_conflicts): Define.
12897 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
12899 Use expected_sr_conflicts in place of expected_conflicts.
12900 Warn if expected_rr_conflicts used in non-GLR parser.
12902 * doc/bison.texinfo: Add documentation for %expect-rr.
12904 2004-03-08 Paul Eggert <eggert@gnu.org>
12906 Add support for hex token numbers. Suggested by Odd Arild Olsen in
12907 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
12909 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
12911 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
12912 * src/scan-gram.l (scan_integer): New function.
12914 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
12915 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
12916 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
12917 Say "long int", not "long", for uniformity with GNU style.
12919 2004-02-25 Paul Eggert <eggert@twinsun.com>
12921 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
12922 compilers. This fixes a problem with Intel's C++ compiler being
12923 chatty, reported by Guido Trentalancia in
12924 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
12926 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
12928 Support %destructor and merge error locations in lalr1.cc.
12930 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
12931 (Parser::stos_): Define unconditionally.
12932 (Parser::destruct_): New method. Generate its body with
12933 b4_yydestruct_generate.
12934 (Parser::error_start_): New attribute.
12935 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
12936 token which are discarded.
12937 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
12938 error_start_ when erroneous token are discarded.
12939 (Parser::parse) <yyerrlab1>: Compute the location of the error
12940 token so that it covers all the discarded tokens.
12941 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
12942 it can be called with `%skeleton "lalr1.cc"', and do that.
12944 2004-02-02 Paul Eggert <eggert@twinsun.com>
12946 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
12947 $(top_srcdir)/lib and ../lib. This fixes a bug reported
12948 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
12949 There's no need to mention top_builddir since Automake does that
12951 (INCLUDES): Remove, as Automake says it's obsolescent.
12952 Contents migrated into AM_CPPFLAGS as described above.
12953 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
12955 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
12957 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
12958 (yyreportSyntaxError): Handle case where lookahead token is
12961 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12963 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
12964 resulting parsers are compilable with C++.
12966 2003-12-23 Paul Eggert <eggert@twinsun.com>
12968 * config/depcomp, config/install-sh: Sync with Automake 1.8.
12969 * src/output.c (output_skeleton): Rename local var.
12970 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
12971 Bison tokens, as this runs afoul of the 2003-10-07 change that
12972 disallowed NUL bytes in character constants or string literals.
12974 * tests/local.at: Require Autoconf 2.59's Autotest.
12975 * tests/testsuite.at: Don't include local.at, since we now assume
12976 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
12978 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
12979 multiple inclusion warnings.
12981 2003-12-02 Akim Demaille <akim@epita.fr>
12983 * doc/bison.texinfo (How Can I Reset the Parser): More about start
12987 2003-11-18 Alexandre Duret-Lutz <adl@gnu.org>
12989 * doc/bison.texinfo (Bison Options): Escape `@' in `$@'.
12991 2003-10-07 Paul Eggert <eggert@twinsun.com>
12993 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
12994 if testsuite doesn't exist.
12996 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
12997 literals, unfortunately.
12998 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
12999 Complain about NUL bytes in character constants or string literals.
13001 2003-10-05 Paul Eggert <eggert@twinsun.com>
13003 * NEWS: Don't document %no-default-prec, as it's still
13005 * doc/bison.texinfo: Document %no-default-prec only if
13006 the defaultprec flag is set. Normally it's not.
13008 2003-10-04 Paul Eggert <eggert@twinsun.com>
13010 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
13011 non-modifiable lvalue, instead of a modifiable one.
13012 * doc/bison.texinfo (Actions): Document that $$ can
13013 be assigned to. Do not claim that $$ and $N are
13014 array element references: user code should not rely on this.
13016 2003-10-01 Paul Eggert <eggert@twinsun.com>
13018 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
13019 (grammar_declaration): Use it.
13020 * src/scan-gram.l: New token %no-default-prec.
13021 * tests/conflicts.at: Revamp tests to use %no-default-prec.
13022 * NEWS, doc/bison.texinfo: Document the above.
13024 2003-10-01 Akim Demaille <akim@epita.fr>
13026 VCG no longer supports long_straight_phase.
13028 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
13029 * src/print_graph.c (print_graph): Adjust.
13031 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
13032 and Paul Eggert <eggert@twinsun.com>
13034 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
13035 Table of Symbols): Document %default-prec.
13036 * src/parse-gram.y (PERCENT_DEFAULT_PREC): New token.
13037 (grammar_declaration): Set default_prec on %default-prec.
13038 * src/scan-gram.l (%default-prec): New token.
13039 * src/reader.h (default_prec): New flag.
13040 * src/reader.c: Likewise.
13041 (packgram): Handle it.
13042 * tests/conflicts.at (%default-prec without %prec,
13043 %default-prec with %prec, %default-prec 1): New tests.
13045 2003-09-30 Paul Eggert <eggert@twinsun.com>
13047 * tests/testsuite.at: Include local.at, not input.at, fixing
13048 a typo in the 2003-08-25 patch.
13050 2003-08-27 Akim Demaille <akim@epita.fr>
13052 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
13055 2003-08-26 Akim Demaille <akim@epita.fr>
13057 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
13058 "<\#" to avoid magic from Gnus when posting parts of this script.
13060 2003-08-26 Akim Demaille <akim@epita.fr>
13062 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
13063 (Parser::parse): here.
13064 Adjust: nerrs and errstatus is now replaced by...
13065 (Parser::nerrs_, Parser::errstatus_): New.
13067 2003-08-25 Akim Demaille <akim@epita.fr>
13069 * config/announce-gen, Makefile.cfg: New.
13070 * Makefile.am: Adjust.
13071 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
13072 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
13074 2003-08-25 Akim Demaille <akim@epita.fr>
13076 When reducing initial empty rules, Bison parser read an initial
13077 location that is not defined. This results in garbage, and that
13078 affects Bison's own parser. Therefore we need (i) to extend Bison
13079 to support a means to initialize this location, and (ii) to use
13080 this CVS Bison to fix CVS Bison's parser.
13082 * src/reader.h, reader.c (epilogue_augment): Remove, replace
13084 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
13085 * src/parse-gram.y: Adjust.
13086 (%initial-action): New.
13087 (%error-verbose): Since we require CVS Bison, there is no reason
13089 * src/scan-gram.l: Adjust.
13090 * src/Makefile.am (YACC): New, to make sure we use our own parser.
13091 * data/yacc.c (yyparse): Use b4_initial_action.
13093 2003-08-25 Akim Demaille <akim@epita.fr>
13095 * doc/bison.texinfo: Don't promote stdout for error messages.
13097 2003-08-25 Akim Demaille <akim@epita.fr>
13099 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
13100 From Alexandre Duret-Lutz.
13102 2003-08-25 Akim Demaille <akim@epita.fr>
13106 2003-08-25 Akim Demaille <akim@epita.fr>
13108 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
13111 2003-08-25 Akim Demaille <akim@epita.fr>
13113 * data/lalr1.cc (Parser::reduce_print_): New.
13116 2003-08-25 Akim Demaille <akim@epita.fr>
13118 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
13119 error recovery loops. This patch is based on
13120 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
13121 Also, augment the similarity between lalr1.cc and yacc.c.
13122 Note: the locations of error recovery rules are not correct yet.
13124 * data/lalr1.cc: Comment changes to augment the similarity between
13125 lalr1.cc and yacc.c.
13126 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
13127 (yyerrlab1): Remove, but where it used to be (now the bottom part of
13128 yyerrlab), when hitting EOF, pop the whole stack here instead of
13129 merely falling thru the default error handling mechanism.
13130 (yyerrorlab): New label, with the old contents of YYERROR,
13131 plus the following change: pop the stack of rhs corresponding
13132 to the production that invoked YYERROR. That is how Yacc
13133 behaves (required by POSIX).
13134 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
13137 2003-08-25 Akim Demaille <akim@epita.fr>
13139 Tune local.at so that people can "autom4te -l autotest calc.at -o
13140 calc" for instance, to extract a sub test suite.
13142 * tests/testsuite.at: Move the initialization, Autotest version
13143 requirement, and AT_TESTED invocation into...
13144 * tests/local.at: here.
13145 * tests/testsuite.at: Include it for compatibility with Autoconf
13147 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
13150 2003-08-04 Paul Eggert <eggert@twinsun.com>
13152 Rework code slightly to avoid gcc -Wtraditional warnings.
13153 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
13154 The returned value is now stored in *YY0. All callers changed.
13155 * src/output.c (merge_output): Adjust to the above change.
13157 2003-07-26 Paul Eggert <eggert@twinsun.com>
13159 * data/glr.c (YYASSERT): New macro.
13160 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
13161 yyresolveStates, yyprocessOneStack):
13162 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
13163 Derived from a suggestion by Frank Heckenbach.
13165 2003-07-25 Paul Eggert <eggert@twinsun.com>
13167 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
13168 for portability to K&R C (after ansi2knr, presumably). See
13169 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
13170 by Frank Heckenbach, though I have omitted the structure-initialization
13171 part of his glr-knr.diff patch since I recall that the Portable
13172 C Compiler didn't require that change.
13174 Let the user specify how to allocate and free memory.
13175 Derived from a suggestion by Frank Heckenbach in
13176 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
13177 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
13178 All uses of free, malloc, realloc changed to use these macros,
13179 and unnecessary casts removed.
13180 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
13182 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
13184 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
13185 use s.empty() rather than s == "" to test for empty string; see
13186 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
13189 2003-06-25 Akim Demaille <akim@epita.fr>
13191 * config/depcomp, config/install-sh: Update from masters.
13193 2003-06-20 Paul Eggert <eggert@twinsun.com>
13195 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
13196 and return properly parenthesized result.
13197 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
13198 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
13199 Remove unnecessary parentheses from uses.

13201 conventions for parentheses.
13203 2003-06-19 Paul Eggert <eggert@twinsun.com>
13205 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
13206 yyreportTree): Do not assume that size_t is the same width as int,
13207 when printing sizes. Print sizes using an unsigned format.
13208 Problem reported by Frank Heckenbach in
13209 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
13211 Port to Forte Developer 7 C compiler.
13212 * data/glr.c (struct YYLTYPE): If locations are not being used,
13213 declare a single dummy member, as empty structs do not conform
13215 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
13216 the Forte Developer 7 C compiler complains that end-of-loop
13217 code is not reached.
13219 2003-06-17 Paul Eggert <eggert@twinsun.com>
13221 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
13222 avoid warnings from picky compilers about redefinition of PARAMS.
13224 2003-06-17 Paul Eggert <eggert@twinsun.com>
13228 * NEWS: Document 1.875b.
13230 * lib/bbitset.h: Do not include config.h; that's the includer's job.
13231 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
13232 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
13233 Don't use 'index' in comments, as it's a builtin fn on some hosts.
13234 * lib/bitset_stats.c: Include gettext.h unconditionally, as
13235 per recent gettext manual's suggestion.
13236 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
13237 Use prototypes, not old-style definitions.
13238 * lib/lbitset.c (lbitset_unused_clear): Likewise.

13253 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
13254 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
13255 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
13256 * lib/vbitset.c, lib/vbitset.h: New files.
13257 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
13258 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
13261 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
13262 `How Can I Reset @code{yyparse}', since texinfo does not allow
13263 arbitrary @ in node names.
13265 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
13266 shouldn't be needed according to the gettext 0.12.1 documentation
13267 but which seem to be needed anyway: codeset.m4 glibc21.m4
13268 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
13269 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

13273 * m4/.cvsignore: Add nls.m4, po.m4.
13275 Upgrade to CVS gnulib.
13276 * stdbool_.h: File renamed from stdbool.h.in.
13277 * configure.ac (AM_STDBOOL_H): Invoke this instead of
13279 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
13280 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
13281 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
13282 (MOSTLYCLEANFILES): New var.
13283 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
13284 (stdbool.h): New rule.

13288 m4/quote.m4: Upgrade to today's gnulib.
13290 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
13291 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
13292 the tests right now.
13293 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
13294 yyerror are declared before use; C99 requires this.
13296 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13298 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
13300 (yyrecoverSyntaxError): Correct the logic for setting and testing
13302 Correct comment on handling EOF.
13303 Allow states with only a default reduction, rather than failing
13304 (I can't quite reconstruct why these were not allowed before).
13306 Fixes to avoid problem that $-N rules in GLR parsers can cause
13307 buffer overruns, corrupting state.
13309 * src/output.c (prepare_rules): Output max_left_semantic_context
13311 * src/reader.h (max_left_semantic_context): New variable declaration.
13312 * src/scan-gram.l (max_left_semantic_context): Define.
13313 (handle_action_dollar): Update max_left_semantic_context.
13314 * data/glr.c (YYMAXLEFT): New definition.
13315 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
13316 (yyresolveAction): Ditto.
13318 Fixes to problems with location handling in GLR parsers reported by
13319 Frank Heckenbach (2003/06/05).
13321 * data/glr.c (YYLTYPE): Make trivial if locations not used.
13322 (YYRHSLOC): Add parentheses, and define only if locations used.
13323 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
13324 locations not used.
13325 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
13326 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
13328 * tests/cxx-type.at: Exercise location information; update tests
13329 to differentiate output with and without locations.
13330 Remove forward declarations of yylex and yyerror---caused errors
13331 because default YYLTYPE not yet defined.
13332 Change semantic actions to compute strings, rather than printing
13333 them directly (to test proper passing of semantics values). Change
13334 output to prefix notation and update test data and expected results.
13335 (yylex): Track locations.
13336 (stmtMerge): Return value rather than printing, and include arguments
13339 2003-06-03 Paul Eggert <eggert@twinsun.com>
13341 Avoid warnings generated by GCC 2.95.4 when Bison is
13342 configured with --enable-gcc-warnings.
13343 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
13344 yy::]b4_parser_class_name[::translate_,
13345 yy::Stack::operator[] (unsigned),
13346 yy::Stack::operator[] (unsigned) const,
13347 yy::Slice::operator[] (unsigned),
13348 yy::Slice::operator[] (unsigned) const):
13349 Rename local vars to avoid warnings.
13350 * tests/glr-regression.at (Improper handling of embedded actions
13351 and $-N in GLR parsers): Remove unused local variable from yylex.
13352 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
13353 (void) as arg when not pure, since we now assume C89 when building
13354 Bison. Pacify GCC by using parameter.
13356 2003-06-02 Paul Eggert <eggert@twinsun.com>
13358 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
13359 yy::Location::lines, yy::Location::columns): Rename arguments
13360 to avoid shadowing; this removes a warning generated by GCC 3.3.
13362 2003-06-01 Paul Eggert <eggert@twinsun.com>
13364 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
13365 to g++, as GCC 3.3 complains if you do it.
13366 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
13367 everything that WARNING_CFLAGS has, except omit warnings
13368 not suitable for C++.
13369 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
13370 * tests/atlocal.in (CXXFLAGS): New var.
13371 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
13373 Fix a GLR parser bug I reported in February; see
13374 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
13375 The problem was that GLR parsers did not conform to the C standard,
13376 because actions like { $1 = $2 + $3; } expanded to expressions
13377 that invoked YYFILL in separate subexpressions, and YYFILL assigned
13378 to a local variable. The C standard says that expressions
13379 like (var = f ()) + (var = f ()) have undefined behavior.
13380 Another problem was that GCC sometimes issues warnings that
13381 yyfill and its parameters are unused.
13383 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
13384 as possibly unused.
13385 (yyfill): New function.
13387 (yyuserAction): Change type of yynormal to bool, so that it matches
13388 the new yyfill signature. Mark it as possibly unused.
13391 Follow up on a bug I reported in February, where a Bison-generated
13392 parser can loop. Provide a test case and a fix for yacc.c. I
13393 don't have a fix for lalr1.cc or for glr.c, unfortunately.
13394 The original bug report is in:
13395 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
13397 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
13398 macro's size was becoming unwieldy.
13399 (yyerrlab): Do not discard an empty lookahead symbol, as this
13400 might destroy garbage.
13401 (yyerrorlab): New label, with the old contents of YYERROR,
13402 plus the following change: pop the stack of rhs corresponding
13403 to the production that invoked YYERROR. That is how Yacc
13404 behaves, and POSIX requires this behavior.
13405 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
13406 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
13407 Define 'alarm' to do nothing if unistd.h is not available.
13408 Add a new rule "exp: '-' error;" to test the above change to
13409 data/yacc.c. Use 'alarm' to abort any test taking longer than
13410 10 seconds, as it's probably looping.
13411 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
13412 Also, the new yacc.c generates two fewer diagnostics for an
13415 2003-05-24 Paul Eggert <eggert@twinsun.com>
13417 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
13418 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
13419 This fixes a problem reported by John Bowman when the Compaq/HP
13420 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
13421 -ansi -Wall -gall).
13422 * data/yacc.c (union yyalloc): Likewise.
13423 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
13425 Switch from 'int' to 'bool' where that makes sense.
13427 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
13428 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,

13430 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
13431 Return or accept bool, not int. All callers changed.
13432 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
13433 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.
13434 * lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_,

13442 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
13443 bitset_stats_or_and_cmp): Likewise.

13450 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
13451 lbitset_xor_cmp): Likewise.
13452 * lib/bbitset.h: Include <stdbool.h>.
13453 (struct bitset_vtable): The following members now return bool, not
13454 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
13455 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
13457 * src/conflicts.c (count_rr_conflicts): Likewise.
13458 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
13460 * lib/ebitset.c (ebitset_obstack_init): Likewise.
13461 * lib/lbitset.c (lbitset_obstack_init): Likewise.
13462 * src/getargs.c (debug_flag, defines_flag, locations_flag,

13473 (long_options, getargs): Use it.
13474 * src/lalr.c (build_relations): Use bool, not int.
13475 * src/nullable.c (nullable_compute): Likewise.
13476 * src/print.c (print_reductions): Likewise.

13479 * src/output.c (prepare): Use it.
13480 * src/output.c (token_definitions_output,

13484 * src/state.c (state_rule_lookaheads_print): Likewise.
13486 * config/install-sh: Sync from automake 1.7.5.
13488 2003-05-14 Paul Eggert <eggert@twinsun.com>
13490 * src/parse-gram.y (rules_or_grammar_declaration): Require a
13491 semicolon after a grammar declaration, in the interest of possible
13492 future changes to the Bison input language.
13493 Do not allow a stray semicolon at the start of the grammar.
13494 (rhses.1): Allow one or more semicolons after any rule, including
13495 just before "|" as required by POSIX.
13496 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
13499 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
13501 %parse-param support for lalr1.cc.
13503 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
13504 b4_cc_constructor_calls, b4_cc_constructor_call,
13505 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
13507 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
13508 parse-param arguments.
13509 (yy::b4_parser_class_name): Declare instance variables to
13510 hold parse-param arguments.
13511 * tests/calc.at: s/value/semantic_value/ because value clashes
13512 with a member of yy::b4_parser_class_name. Adjust C++ code
13513 to handle %parse-param. Enable %parse-param test in C++.
13515 2003-05-12 Paul Eggert <eggert@twinsun.com>
13517 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
13518 English a bit. Fix fclose typo. Change "const char" to "char
13519 const", and use ANSI C rather than K&R for "main". Suggest
13520 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
13521 and suggest yy_switch_to_buffer.
13523 2003-05-05 Paul Eggert <eggert@twinsun.com>
13525 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
13526 C89. This avoids a diagnostic on compilers that define __STDC__
13527 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
13528 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
13530 2003-05-03 Paul Eggert <eggert@twinsun.com>
13532 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
13533 Do not overrun array bounds.
13534 This should fix a bug reported today by Olatunji Oluwabukunmi in
13535 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
13537 2003-04-29 Akim Demaille <akim@epita.fr>
13539 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
13540 * src/getargs.c, src/getargs.h: here, as bool, not int.
13541 (nondeterministic_parser): New.
13542 * src/parse-gram.y, src/scan-gram.l: Support
13543 %nondeterministic-parser.
13544 * src/output.c (prepare): Use nondeterministic_parser instead
13545 of glr_parser where appropriate.
13546 * src/tables.c (conflict_row, action_row, save_row)
13547 (token_actions, token_actions, pack_vector): Ditto.
13549 2003-04-29 Akim Demaille <akim@epita.fr>
13551 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
13553 2003-04-29 Akim Demaille <akim@epita.fr>
13555 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
13556 with %pure-parser and %locations to exercise the patch from Yakov
13559 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
13561 * data/yacc.c: (b4_lex_param): Corrected for the case where
13562 %lex-param is provided and %pure-parser isn't.
13564 2003-04-27 Paul Eggert <eggert@twinsun.com>
13566 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
13567 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
13568 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
13569 if it is not defined.
13570 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
13572 2003-04-26 Paul Eggert <eggert@twinsun.com>
13574 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
13575 Declare to be of type suitable for the ninf value itself, not of
13576 type suitable for the corresponding table, since the latter might
13577 be unsigned but the ninf value might be negative. This fixes a
13578 bug reported by Alexandre Duret-Lutz in
13579 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
13581 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
13582 invokes it. We shouldn't invoke it twice because it will attempt
13583 to put error.o in the archive twice. This fixes a glitch reported
13584 by Martin Mokrejs in
13585 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
13587 2003-04-21 Paul Eggert <eggert@twinsun.com>
13589 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
13592 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
13594 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
13595 Fix obvious typo that results in uncompilable GLR parsers
13596 when both %pure-parser and %locations are used. (trivial change)
13598 2003-04-17 Paul Eggert <eggert@twinsun.com>
13600 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
13601 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
13602 Do not insert the expected token via unput, as this runs afoul
13603 of a POSIX-compatibility bug in flex 2.5.31.
13604 All uses changed to BEGIN the parent state,
13605 since we no longer insert the expected token via unput.
13606 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
13607 that is no longer emitted after the above change.
13609 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
13610 the first one. This change is from Paul Hilfinger, and it fixes
13611 regression reported by Werner Lemberg in
13612 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
13614 (resolve_sr_conflict): Don't invoke state_errs_set
13615 unless one or more tokens have been explicitly made errors.
13616 Otherwise, the above change causes Bison to abort.
13618 * tests/existing.at (GNU pic Grammar): New test case, taken from
13621 2003-03-31 Akim Demaille <akim@epita.fr>
13623 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
13625 2003-03-31 Akim Demaille <akim@epita.fr>
13627 * src/output.c (prepare_symbols): Avoid trailing spaces in the
13630 2003-03-31 Akim Demaille <akim@epita.fr>
13632 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
13633 From Paul Hilfinger.
13635 2003-03-29 Akim Demaille <akim@epita.fr>
13637 * m4/error.m4: Do not put under dynamic conditions some code which
13638 expansion is under static control.
13640 2003-03-29 Akim Demaille <akim@epita.fr>
13642 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
13644 2003-03-29 Akim Demaille <akim@epita.fr>
13646 * doc/bison.texinfo (Strings are Destroyed): New.
13648 2003-03-13 Paul Eggert <eggert@twinsun.com>
13650 * .cvsignore: Add configure.lineno.
13651 * src/.cvsignore: Add yacc.
13652 * tests/.cvsignore: Add testsuite.log.
13653 * doc/fdl.texi: Sync with latest FSF version.
13655 2003-03-12 Paul Eggert <eggert@twinsun.com>
13657 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
13658 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
13659 cursor, instead of leaving it undefined. This fixes a bug
13660 reported by Tim Van Holder in
13661 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
13662 * tests/input.at (Torturing the Scanner): Test the scanner on
13663 an empty input file, which was Tim Van Holder's test case.
13665 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
13666 <sys/resource.h> can be included, include sys/time.h and
13667 sys/times.h first, if available. This works around the SunOS
13668 4.1.4 porting bug reported by Bruce Becker in
13669 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
13671 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
13672 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
13673 AC_HEADER_SYS_WAIT.
13675 Merge changes from gnulib. This was prompted because the CVS
13676 snapshot didn't build on Solaris 7 due to strnlen problems.
13678 These changes need to be merged back into gnulib:
13679 * lib/hash.c: Include <stdbool.h> unconditionally.
13680 * m4/onceonly.m4 (m4_quote): New macro.
13681 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
13682 Quote AC_FOREACH variable-expansions properly.
13683 The 2003-01-03 obstack.h change also needs merging.
13684 {end of changes requiring merging}
13686 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
13687 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
13688 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,

13690 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
13691 New files, imported from gnulib.
13692 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
13695 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
13696 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
13699 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
13701 (gl_ERROR): New, replacing jm_PREREQ_ERROR.

13705 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
13706 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
13707 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
13708 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
13709 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
13710 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
13711 (jm_PREREQ_ARGMATCH): Remove.
13712 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
13713 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
13715 * src/system.h: Include <stdbool.h> unconditionally.
13717 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
13718 assuming at least C89 in the bitset code for some time now.
13720 2003-03-03 Akim Demaille <akim@epita.fr>
13724 2003-03-02 Akim Demaille <akim@epita.fr>
13726 * doc/bison.texinfo (Table of Symbols): Reactivate the
13727 documentation for %lex-param, and %parse-param.
13729 2003-03-02 Akim Demaille <akim@epita.fr>
13731 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
13732 generate verbose error messages.
13733 Use the number of tokens as an upper bound in yytname, as it
13734 cannot be a non terminal.
13736 2003-03-02 Akim Demaille <akim@epita.fr>
13738 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
13741 2003-03-02 Akim Demaille <akim@epita.fr>
13743 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
13744 Use them to exercise yycheck overrun.
13745 Based on Andrew Suffield's grammar.
13747 2003-03-02 Akim Demaille <akim@epita.fr>
13749 Create tests/local.at for Bison generic testing macros.
13751 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
13752 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):

13755 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
13756 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
13757 * tests/local.at: here.
13758 (AT_COMPILE_CXX): Tags the tests using it as c++.
13759 Ignore the test if CXX is not functional.
13761 2003-03-01 Paul Eggert <eggert@twinsun.com>
13763 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
13764 not loc->end, since loc->end might contain garbage and this leads
13765 to undefined behavior on some platforms.
13766 (id_loc, token_start): Use (IF_LINTed) initial values that do not
13767 depend on *loc, so that the reader doesn't give the the false
13768 impression that *loc is initialized.
13769 (<INITIAL>"%%"): Do not bother setting code_start, since its value
13770 does not survive the return.
13772 2003-03-01 Akim Demaille <akim@epita.fr>
13774 * src/scan-gram.l (code_start): Always initialize it when entering
13775 into yylex, as SC_EPILOGUE is activated *before* the corresponding
13776 yylex invocation. An alternative would be making it static, but
13777 then it starts with the second %%'s beginning, instead of its end.
13779 2003-02-28 Paul Eggert <eggert@twinsun.com>
13781 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
13782 around a UnixWare 7.1.1 porting bug reported by John Hughes in
13783 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
13785 2003-02-26 Paul Eggert <eggert@twinsun.com>
13787 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
13788 Remove Sequent/Pyramid discussion (nobody uses them any more).
13789 Merge VMS and MS-DOS discussion; these ports may well be dead
13790 but let's keep mentioning them for now. Put <> around email
13791 addresses. Add copyright notice.
13793 2003-02-24 Paul Eggert <eggert@twinsun.com>
13795 * data/glr.c (yy_reduce_print): yylineno -> yylno,
13796 to avoid collision with flex use of yylineno.

13807 change integer types.
13808 Suggested by Paul Eggert.
13810 2003-02-21 Akim Demaille <akim@epita.fr>
13812 * doc/bison.texinfo: Use "location" consistently to refer to @n,
13813 to avoid confusions with lalr1.cc's notion of Position.
13814 Suggested by Paul Eggert.
13816 2003-02-20 Akim Demaille <akim@epita.fr>
13818 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
13819 before initial_columns.
13820 (location.hh): Use consistent variable names when defining the
13822 Use "last" so that we subtract from Positions, not from unsigned.
13824 2003-02-20 Akim Demaille <akim@epita.fr>
13826 * data/lalr1.cc (position.hh): New subfile, including the extended
13827 and Doxygen'ed documentation of class Position.
13828 (location.hh): Use it.
13829 Document a` la Doxygen.
13830 With the help of Benoit Perrot.

13836 Redefine AT_YYERROR_SEES_LOC_IF using it.
13837 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
13839 Don't use the location in yy::Parser::error_ and
13840 yy::Parser::print_ when not %locations.
13841 Activate more lalr1.cc tests.
13843 2003-02-19 Akim Demaille <akim@epita.fr>
13845 * data/lalr1.cc: When displaying a line number, be sure to make it
13848 2003-02-19 Akim Demaille <akim@epita.fr>
13850 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
13852 (YYABORT, YYACCEPT, YYERROR): New.
13853 * tests/calc.at: Renable the lalr1.cc test.
13855 2003-02-19 Akim Demaille <akim@epita.fr>
13857 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
13858 error recovery, mixing with/without pops and discarding of the

13875 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
13876 Check for malloc failure, for consistency with yacc.c.
13877 (yytname_size): Remove, for consistency with yacc.c.
13879 The bug still remains in data/lalr1.cc, as I didn't have time
13882 2003-02-06 Akim Demaille <akim@epita.fr>

13908 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
13909 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
13910 these CPP macros with the m4 macros new defined by...

14002 Changes in response to error report by S. Eken: GLR mode does not
14003 handle negative $ indices or $ indices in embedded rules correctly.
14004 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.

14032 * data/lalr1.cc: Do not use @output_header_name@ unless
14033 b4_defines_flag is set. This fixes two bugs reported by
14035 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
14036 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
14038 2003-01-21 Paul Eggert <eggert@twinsun.com>
14040 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
14041 we don't need to worry about yyerrlab1 being reported as an
14042 "unused label" by non-GCC C compilers. The downside is that if
14043 locations are used then a couple of statements are duplicated each
14044 time YYERROR is invoked, but the upside is that the warnings
14046 (yyerrlab1): Move code to YERROR.
14047 (yyerrlab2): Remove. Change uses back to yyerrlab1.
14048 This reverts some of the 2002-12-27 change.
14050 2003-01-17 Paul Eggert <eggert@twinsun.com>
14052 * src/output.c (symbol_printers_output): Fix typo that led
14053 to core dump. Problem reported by Antonio Rus in
14054 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
14056 2003-01-13 Akim Demaille <akim@epita.fr>,
14057 Quoc Peyrot <chojin@lrde.epita.fr>,
14058 Robert Anisko <anisko_r@lrde.epita.fr>
14060 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
14061 when the stacks contain one element, as the loop would otherwise
14062 free the last state, and then use the top state (the one we just
14063 popped). This means that the initial elements will not be freed
14064 explicitly, as is the case in yacc.c; it is not a problem, as
14065 these elements have fake values.
14067 2003-01-11 Paul Eggert <eggert@twinsun.com>
14069 * NEWS: %expect-violations are now just warnings, reverting
14070 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
14071 bootstrapping problem reported by Matthias Klose; see
14072 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
14073 * src/conflicts.c (conflicts_print): Likewise.
14074 * tests/conflicts.at (%expect not enough, %expect too much,
14075 %expect with reduce conflicts): Likewise.
14076 * doc/bison.texinfo (Expect Decl): Document this. Also mention
14077 that the warning is enabled if the number of conflicts changes
14078 (not necessarily increases).
14080 * src/getargs.c (version): Update copyright year.
14082 2003-01-09 Akim Demaille <akim@epita.fr>
14084 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
14086 2003-01-08 Paul Eggert <eggert@twinsun.com>
14088 * Makefile.maint (WGETFLAGS):
14089 New macro, containing "-C off" to disable proxy caches.
14090 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
14091 (rel-check): Use $(WGET) instead of wget.
14093 2003-01-06 Paul Eggert <eggert@twinsun.com>
14095 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
14096 the GLR paper of Scott, Johnstone and Hussain.
14098 2003-01-04 Paul Eggert <eggert@twinsun.com>
14100 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
14101 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
14102 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
14103 (EXTRA_LIBRARIES): New var, for liby.a.
14104 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
14105 (EXTRA_SCRIPTS): New var, for yacc.
14107 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
14108 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
14109 Problem reported by Nelson H. F. Beebe.
14111 2003-01-03 Paul Eggert <eggert@twinsun.com>
14113 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
14114 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
14115 when compiling Bison 1.875's `bitset bset = obstack_alloc
14116 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
14118 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
14119 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
14120 grow to a huge size with typical invocation.
14122 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
14123 Use the pattern recommended by Autoconf 2.57, except also protect
14124 against double-definition.
14125 * src/system.h: Likewise.
14126 Portability issues reported by Nelson H. F. Beebe.
14128 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
14129 All uses changed. Provide a definition in both C and C++.
14130 (yytrue, yyfalse): Define even if defined (__cplusplus).
14132 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
14133 Reported by Nelson H. F. Beebe.
14135 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
14137 2003-01-02 Paul Eggert <eggert@twinsun.com>
14139 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
14140 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
14141 Bug reported by Nelson H. F. Beebe.
14143 2003-01-01 Paul Eggert <eggert@twinsun.com>
14147 2002-12-30 Paul Eggert <eggert@twinsun.com>
14149 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
14151 (<INITIAL>","): Here. This causes stray "," to be treated
14154 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
14155 last brace in braced code when not in Yacc mode, for compatibility
14156 with Bison 1.35. This resurrects the 2001-12-15 patch to
14159 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
14160 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
14162 2002-12-28 Paul Eggert <eggert@twinsun.com>
14164 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
14165 that of SYM's type. This fixes Debian bug 168069, reported by
14168 2002-12-28 Paul Eggert <eggert@twinsun.com>
14172 Switch back to the Yacc style of conflict reports, undoing some
14173 of the 2002-07-30 change.
14174 * doc/bison.texinfo (Understanding): Use Yacc style for
14175 conflict reports. Also, use new way of locating rules.
14176 * src/conflicts.c (conflict_report):
14177 Renamed from conflict_report_yacc, removing the old
14178 'conflict_report'. Translate the entire conflict report at once,
14179 so that we don't assume that "," has the same interpretation in
14181 (conflicts_output): Use Yacc-style conflict report for each state,
14182 instead of our more-complicated style.
14183 (conflicts_print): Use Yacc-style conflict report, except print
14184 the input file name when not emulating Yacc.
14185 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
14186 Conflicted Reduction, %expect not enough, %expect too much,
14187 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
14188 * tests/existing.at (GNU Cim Grammar): Likewise.
14189 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
14191 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
14192 fatal): Don't invoke fflush; it's not needed and it might even be
14193 harmful for stdout, as stdout might not be open.
14194 * src/reduce.c (reduce_print): Likewise.
14196 2002-12-27 Paul Eggert <eggert@twinsun.com>
14198 Fix a bug where error locations were not being recorded correctly.
14199 This problem was originally reported by Paul Hilfinger in
14200 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
14202 * data/yacc.c (yyparse): New local var yylerrsp, to record the
14203 top of the location stack's error locations.
14204 (yyerrlab): Set it. When discarding a token, push its location
14205 onto yylerrsp so that we don't lose track of the error's end.
14206 (yyerrlab1): Now is only the target of YYERROR, so that we can
14207 properly record the location of the action that failed. For GCC
14208 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
14209 GCC warning about yyerrlab1 being unused if YYERROR is unused.
14210 (yyerrlab2): New label, which yyerrlab now falls through to.
14211 Compute the error's location by applying YYLLOC_DEFAULT to
14212 the locations of all the symbols that went into the error.
14213 * doc/bison.texinfo (Location Default Action): Mention that
14214 YYLLOC_DEFAULT is also invoked for syntax errors.
14215 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
14216 Error locations include the locations of all the tokens that were
14217 discarded, not just the last token.
14219 2002-12-26 Paul Eggert <eggert@twinsun.com>
14221 * src/files.c: Include quote.h.
14222 (compute_output_file_names): Warn if we detect conflicting
14223 outputs to the same file. This should catch the misunderstanding
14224 exemplified by Debian Bug 165349, reported by Bruce Stephens..
14226 * src/conflicts.c (conflicts_print): If the user specifies
14227 "%expect N", report an error if there are any reduce/reduce
14228 conflicts. This is what the manual says should happen.
14229 This fixes Debian bug 130890, reported by Anthony DeRobertis.
14230 * tests/conflicts.at (%expect with reduce conflicts): New test.
14232 Don't use m4_include on relative file names, as it doesn't work as
14233 desired if there happens to be a file with that name under ".".
14235 * m4sugar/version.m4: Remove; it was included but it wasn't used.
14236 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
14237 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
14238 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
14239 * src/output.c (output_skeleton): Use full path names when
14240 specifying a file to include; don't rely on include path, as
14241 it's unreliable when the working file contains a file with
14244 2002-12-25 Paul Eggert <eggert@twinsun.com>
14246 Remove obsolete references to bison.simple and bison.hairy.
14247 Problem mentioned by Aubin Mahe in
14248 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
14249 * data/glr.c: Comment fix.
14250 * doc/bison.1: Remove references. Also, mention "yacc".
14252 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
14255 * src/parse-gram.y (declaration): Use enum "report_states" rather
14256 than its numeric value 1.
14258 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
14259 opening a new one. This fixes Debian bug 165349, reported by
14262 2002-12-24 Paul Eggert <eggert@twinsun.com>
14266 * Makefile.maint (cvs-update): Don't assume that the shell
14267 supports $(...), as Solaris sh doesn't.
14269 * src/parse-gram.y (lloc_default): Remove test for empty
14270 nonterminals at the end, since it didn't change the result.
14272 2002-12-24 Paul Eggert <eggert@twinsun.com>
14274 If the user does not define YYSTYPE as a macro, Bison now declares it
14275 using typedef instead of defining it as a macro. POSIX requires this.
14276 For consistency, YYLTYPE is also declared instead of defined.
14278 %union directives can now have a tag before the `{', e.g., the
14279 directive `%union foo {...}' now generates the C code
14280 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
14281 The default union tag is `YYSTYPE', for compatibility with Solaris 9
14282 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
14283 instead of `yyltype'.
14285 `yystype' and `yyltype' are now obsolescent macros instead of being
14286 typedefs or tags; they are no longer documented and will be
14287 withdrawn in a future release.
14289 * data/glr.c (b4_location_type): Remove.
14290 (YYSTYPE): Renamed from yystype.
14291 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
14292 (struct YYLTYPE): Renamed from struct yyltype.
14293 (YYLTYPE): Renamed from yyltype.
14294 (yyltype, yystype): New (and obsolescent) macros,
14295 for backward compatibility.
14296 * data/yacc.c: Likewise.
14298 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
14299 does not specify a union tag. This is for compatibility with
14302 * src/parse-gram.y (add_param): 2nd arg is now char * not char
14303 const *, since it is now modified by stripping surrounding { }.
14304 (current_braced_code): Remove.
14305 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
14306 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
14307 trailing " {...}". Now of type <chars>.
14308 (grammar_declaration): Adjust to bundled tokens.
14309 (code_content): Remove; stripping is now done by add_param.
14310 (print_token_value): Print contents of bundled tokens.
14311 (token_name): New function.
14313 * src/reader.h (braced_code, current_braced_code): Remove.
14314 (token_name): New decl.
14316 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
14317 token_type, not braced_code code_kind. All uses changed.
14318 (SC_PRE_CODE): New state, for scanning after a keyword that
14319 has (or usually has) an immediately-following braced code.
14320 (token_type): New local var, to keep track of which token type
14321 to return when scanning braced code.
14322 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
14323 <INITIAL>"%parse-param", <INITIAL>"%printer",
14324 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
14325 instead of returning a token type immediately.
14326 (<INITIAL>"{"): Set token type.
14327 (<SC_BRACED_CODE>"}"): Use it.
14328 (handle_action_dollar, handle_action_at): Now returns bool
14329 indicating success. Fail if ! current_rule; this prevents a core dump.
14330 (handle_symbol_code_dollar, handle_symbol_code_at):
14331 Remove; merge body into caller.
14332 (handle_dollar, handle_at): Complain in invalid contexts.
14334 * NEWS, doc/bison.texinfo: Document the above.
14335 * NEWS: Fix years and program names in copyright notice.
14337 2002-12-17 Paul Eggert <eggert@twinsun.com>
14339 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
14340 Reporting, Table of Symbols): Omit mentions of %lex-param and
14341 %parse-param from the documentation for now.
14343 2002-12-15 Paul Eggert <eggert@twinsun.com>
14345 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
14346 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
14347 lookahead symbol, and which sets yychar in parser actions) and it
14348 disagreed with the Bison documentation. Bug
14349 reported by Andrew Walrond.
14351 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
14352 as the caller now does that.
14353 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
14354 (YYEMPTY): Parenthesize right hand side, since others use it.
14355 (yyparse): Don't assume that our generated code is the only code
14358 2002-12-13 Paul Eggert <eggert@twinsun.com>
14362 POSIX requires a "yacc" command.
14363 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
14364 (MOSTLYCLEANFILES): Add yacc.
14366 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
14367 as an alias for bison y.
14369 * po/LINGUAS: Add da.
14371 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
14372 problem with latest <getopt.h>.
14373 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
14375 * doc/fdl.texi: Upgrade to 1.2.
14376 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
14377 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
14378 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
14380 * config/install-sh: Sync with autotools.
14382 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
14383 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
14384 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
14385 locations are requested.
14386 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
14387 locations are requested.
14389 2002-12-12 Paul Eggert <eggert@twinsun.com>
14391 Remove unportable casts and storage allocation tricks.
14392 While we're at it, remove almost all casts, since they
14393 usually aren't needed and are a sign of trouble.
14395 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
14397 * src/derives.c (derives_compute): Do not subtract NTOKENS from
14398 the pointer DSET returned by malloc; this isn't portable.
14399 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
14400 Similarly for DERIVES.
14401 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
14402 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
14403 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
14405 * src/derives.c (derives_compute): Do not bother invoking
14406 int_of_rule_number, since rule numbers are integers.
14408 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
14409 rather than XMALLOC (char, N).
14411 * src/files.c (filename_split): Rewrite to avoid cast.
14413 * src/gram.h (symbol_number_as_item_number,
14414 item_number_as_symbol_number, rule_number_as_item_number,
14415 item_number_as_rule_number):
14416 Now inline functions rather than macros, to avoid casts.
14417 * src/state.h (state_number_as_int): Likewise.
14418 * src/tables.c (state_number_to_vector_number,
14419 symbol_number_to_vector_number): Likewise.
14421 * src/gram.h (int_of_rule_number): Remove; no longer used.
14423 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
14424 since the resulting storage is always stored into.
14426 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
14429 * src/muscle_tab.c (muscle_m4_output):
14430 Now inline. Return bool, not int.
14431 * src/state.c (state_compare): Likewise.
14432 * src/symtab.c (symbol_check_defined,
14433 symbol_check_alias_consistency, symbol_pack, symbol_translation,
14434 hash_compare_symbol, hash_symbol):
14436 * src/uniqstr.c (uniqstr_print): Likewise.
14437 * src/muscle_tab.c (muscle_m4_output_processor):
14438 New function, to avoid casts.
14439 * src/state.c (state_comparator, stage_hasher): Likewise.
14440 * src/symtab.c (symbol_check_defined_processor,
14441 symbol_check_alias_consistency_processor, symbol_pack_processor,
14442 symbol_translation_processor, hash_symbol_comparator,
14443 hash_symbol_hasher): Likewise.
14444 * src/uniqstr.c (uniqstr_print_processor): Likewise.
14445 * src/muscle_tab.c (muscles_m4_output):
14446 Use new functions instead of casting old functions unportably.
14447 * src/state.c (state_hash_new): Likewise.
14448 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
14449 symbols_token_translations_init):
14451 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
14453 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
14454 var instead of casting to long, to avoid casts.
14455 (prepare_states): Use MALLOC rather than alloca, so that we don't
14456 have to worry about alloca.
14457 * src/state.c (state_hash_lookup): Likewise.
14459 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
14460 local var instead of casting to unsigned char, to avoid casts.
14462 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
14463 STATE_ALLOC): Remove.
14464 (transitions_new, errs_new, reductions_new, state_new): Use malloc
14465 rather than calloc, and use offsetof to avoid allocating slightly
14467 (state_new): Initialize all members.
14469 * src/state.c (state_hash): Use unsigned accumulator, not signed.
14471 * src/symtab.c (symbol_free): Remove; unused.
14472 (symbol_get): Remove cast in lhs of assignment.
14473 (symbols_do): Now static. Accept generic arguments, not
14474 hashing-related ones.
14476 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
14477 (symbol_processor): Remove.
14478 (symbols_do): Remove decl; now static.
14480 * src/system.h (alloca): Remove; decl no longer needed.
14481 (<stddef.h>): Include, for offsetof.
14482 (<inttypes.>, <stdint.h>): Include if available.
14483 (uintptr_t): New type, if system lacks it.
14484 (CALLOC, MALLOC, REALLOC): New macros.
14485 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
14488 * src/tables.c (table_size): Now int, to pacify GCC.
14489 (table_grow, table_ninf_remap): Use signed table size.
14490 (save_row): Don't bother initializing locals when not needed.
14491 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
14492 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
14494 * src/vcg.h: Correct misspellings.

14499 * src/getargs.c (getargs): Don't assume EOF == -1.
14501 2002-12-09 Paul Eggert <eggert@twinsun.com>
14503 Change identifier spellings to avoid collisions with names
14504 that are reserved by POSIX.
14506 Don't use names ending in _t, since POSIX reserves them.
14507 For consistency, remove _e and _s endings -- they're weren't
14508 needed to remove ambiguity. All uses changed.
14509 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
14510 turn was just renamed from struniq_t.
14511 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
14512 which in turn was just renamed from struniq_processor_t.
14513 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
14514 in turn was renamed from hash_compare_struniq_t.

14583 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
14584 value_t_as_yystype -> value_as_yystype.
14586 Don't include <errno.h> in the mainstream code, since it
14587 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
14588 * lib/get-errno.c, lib/get-errno.h: New files.
14589 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
14591 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
14592 * src/output.c (output_skeleton): Likewise.
14593 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno

14599 (TAB_EXT): Renamed from EXT_TAB.
14600 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
14602 Avoid str[a-z]*, since <string.h> reserves that name space.
14603 Change all instances of "struniq" in names to "uniqstr", and
14604 likewise for "STRUNIQ" and "UNIQSTR".
14605 * src/uniqstr.c: Renamed from src/struniq.c.
14606 * src/uniqstr.h: Renamed from src/struniq.h.
14607 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.
14608 * src/files.c (strsuffix): Remove; unused.
14609 (concat2): Renamed from stringappend. Now static.
14610 * src/files.h (strsuffix, stringappend): Remove; unused.
14611 * src/parse-gram.y (<chars>): Renamed from <string>.

14617 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
14618 (N_EXPAND): Renamed from N_STRETCH.

14622 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):

14628 (BASE_MAXIMUM): Renamed from BASE_MAX.
14629 (BASE_MINIMUM): Renamed from BASE_MIN.
14630 (ACTION_MAX): Remove; unused.
14631 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
14632 Unnecessary casts removed from above defines.
14635 Fix misspelling in names.
14636 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
14637 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
14641 * lib/timevar.c (timevar_report): Renamed from time_report,
14642 for consistency with other names.
14643 * lib/timevar.h (timevar_report): New decl.
14644 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
14647 Sort include-file uses.
14649 Reorder all include files under src to be in the order "system.h".
14650 then the ../lib include files in angle brackets (alphabetized),
14651 then the . include files in double-quotes (alphabetized). Fix
14652 dependency breakages encountered in this process, as follows:
14653 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
14654 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
14655 * src/state.h: Include "symtab.h".
14657 2002-12-08 Paul Eggert <eggert@twinsun.com>
14659 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
14660 since this causes problems when __file__ contains character
14661 sequences like "@" that are treated specially by src/scan-skel.l.
14662 Instead, just use the file's basename. This fixes the bug
14663 reported by Martin Mokrejs in
14664 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
14666 2002-12-06 Paul Eggert <eggert@twinsun.com>
14668 Add support for rules that do not have trailing semicolons, as
14669 POSIX requires. Improve the quality of locations in Bison
14672 * src/location.c: Include <quotearg.h>.
14673 (empty_location): Now const.
14674 (location_print): New function. Follow the recommendation of the
14675 GNU Coding Standards for locations that span file boundaries.
14676 * src/location.h: Do not include <quotearg.h>; no longer needed.
14677 (boundary): New type.
14678 (location_t): Use it. This allows locations to span file boundaries.
14679 All member uses changed: file -> start.file or end.file (as needed),
14680 first_line -> start.line, first_column -> start.column,
14681 last_line -> end.line, last_column -> end.column.
14682 (equal_boundaries): New function.
14683 (LOCATION_RESET, LOCATION_STEP): Remove.
14684 (LOCATION_PRINT): Remove. All callers changed to use location_print.
14685 (empty_location): Now const.
14686 (location_print): New decl.
14687 * src/parse-gram.y (lloc_default): New function, which handles
14688 empty locations more accurately.
14689 (YYLLOC_DEFAULT): Use it.
14690 (%token COLON): Remove.
14691 (%token ID_COLON): New token.
14693 (declarations, rules): Remove trailing semicolon.
14694 (declaration, rules_or_grammar_declaration):
14695 Allow empty (";") declaration.
14696 (symbol_def): Remove empty actions; no longer needed.
14697 (rules_or_grammar_declaration): Remove trailing semicolon.
14698 (semi_colon.opt): Remove.
14699 * src/reader.h: Include location.h.
14700 (scanner_cursor): New decl.
14701 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
14703 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
14705 (STEP): Remove. No longer needed, now that adjust_location does
14706 the work. All uses removed.
14707 (scanner_cursor): New var.
14708 (adjust_location): Renamed from extend_location. It now sets
14709 *loc and adjusts the scanner cursor. All uses changed.
14710 Don't bother testing for CR.
14711 (handle_syncline): Remove location arg; now updates scanner cursor.
14712 All callers changed.
14713 (unexpected_end_of_file): Now accepts start boundary of token or
14714 comment, not location. All callers changed. Update scanner cursor,
14716 (SC_AFTER_IDENTIFIER): New state.
14717 (context_state): Renamed from c_context. All uses changed.
14718 (id_loc, code_start, token_start): New local vars.
14719 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
14720 processing of Yacc white space and equivalents here.
14721 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
14722 instead of returning ID immediately, since we need to search for
14723 a subsequent colon.
14724 (<INITIAL>"'", "\""): Save token_start.
14725 (<INITIAL>"%{", "{", "%%"): Save code_start.
14726 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
14727 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
14728 BEGIN context_state at end, not INITIAL.
14729 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
14730 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
14731 Return correct token start.
14732 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
14733 the start of a character, string or multiline comment is found.
14734 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
14735 Reduction): Adjust reported locations to match the more-precise
14736 results now expected.
14737 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
14738 * tests/reduce.at (Useless Rules, Reduced Automaton,
14739 Underivable Rules): Likewise.
14740 * tests/regression.at (Invalid inputs): No longer `expecting ";"
14741 or "|"' now that so many other tokens are allowed by the new grammar.
14743 * src/complain.h (current_file): Remove duplicate decl;
14744 current_file is now owned by files.h.
14745 * src/complain.c, src/scan-gram.l: Include files.h.
14747 2002-12-06 Paul Eggert <eggert@twinsun.com>
14749 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
14750 promotes to int; it might be unsigned int.
14751 * data/yacc.c (yy_reduce_print): Likewise.
14753 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
14754 be #defined in the prologue, not in the Bison declarations.
14755 This fixes Debian Bug 102878, reported by Shaul Karl.
14757 2002-12-02 Paul Eggert <eggert@twinsun.com>
14759 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
14760 * lib/strtoul.c: New file, from gnulib.
14761 This fixes a porting bug reported by Peter Klein in
14762 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
14764 2002-11-30 Paul Eggert <eggert@twinsun.com>
14766 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
14767 and put only a forward declaration in the prologue. This is for
14768 consistency with the other scanner helper functions.
14770 Type clashes now generate warnings, not errors, since it
14771 appears that POSIX may allow some grammars with type clashes.
14772 * src/reader.c (grammar_current_rule_check): Warn about
14773 type clashes instead of complaining.
14774 * tests/input.at (Type Clashes): Expect warnings, not complaints.
14776 Add Yacc library, since POSIX requires it.
14777 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
14778 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
14779 * lib/main.c, lib/yyerror.c: New files.
14781 gram_error can be static; it need not be extern.
14782 * src/reader.h (gram_error): Remove decl.
14783 * src/parse-gram.y (gram_error): Now static. Add static decl.
14784 (print_token_value): Omit parameter names from forward decl,
14787 2002-11-29 Paul Eggert <eggert@twinsun.com>
14789 * doc/bison.texinfo: Emphasize that yylex and yyerror must
14790 be declared before being used. E.g., one should typically
14791 declare them in the prologue. Use GNU coding style in examples.
14792 Put "const" consistently after the type it modifies. Mention
14793 that C99 supports "inline". Mention that yyerror traditionally
14796 %parse-param and %lex-param now take just one argument, the
14797 declaration; the argument name is deduced from the declaration.
14799 * doc/bison.texinfo (Parser Function, Pure Calling, Error
14800 Reporting, Table of Symbols): Document this.
14801 * src/parse-gram.y (add_param): New function.
14803 (declaration): Implement new rule for %parse-param and %lex-param.
14804 * src/scan-gram.l: "," now elicits a warning, rather than being
14805 a token; this is more compatible with byacc.
14806 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
14808 2002-11-27 Paul Eggert <eggert@twinsun.com>
14810 Rename identifiers to avoid real and potential collisions.
14812 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
14813 to avoid collision with lex macro described by Bruce Lilly in
14814 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
14815 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
14816 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
14817 * src/parse-gram.y (print_token_value): Renamed from yyprint.
14819 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
14820 The name "yycontrol" violates the name space rules, and this stuff
14821 wasn't being used anyway.
14822 (input): Remove action; this stuff wasn't being used.
14823 (gram_error): Rename local variable yylloc -> loc.
14824 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
14825 (YY_DECL): Don't use "yy" at start of local variables.
14826 All uses changed, e.g., yylloc -> loc.
14827 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
14828 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
14829 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
14830 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
14832 * src/parse-gram.y (gram_error): loc is now const *.
14833 * src/reader.h (gram_error): Likewise.
14835 2002-11-24 Paul Eggert <eggert@twinsun.com>
14839 * tests/actions.at (Actions after errors): Use an output format
14840 more similar to that of the Printers and Destructors test.
14841 Test the position of the ';' token too.
14842 (Printers and Destructors): Likewise.
14843 (Printers and Destructors: %glr-parser): Remove for now, to avoid
14844 unnecessarily alarming people when the test fails.
14846 * data/yacc.c (yyerrlab1): Move this label down, so that the
14847 parser does not discard the lookahead token if the user code
14848 invokes YYERROR. This change is required for POSIX conformance.
14850 * lib/error.c: Sync with gnulib.
14852 2002-11-22 Paul Eggert <eggert@twinsun.com>
14854 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
14855 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
14856 * lib/xmalloc.c: Likewise.
14858 2002-11-20 Paul Eggert <eggert@twinsun.com>
14860 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
14862 2002-11-20 Paul Eggert <eggert@twinsun.com>
14864 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
14865 should use `if (! x) abort ();' rather than `assert (x);', and
14866 anyway it's one less thing to worry about configuring.
14868 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
14869 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
14870 and replace all instances of assert with abort.
14871 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
14872 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
14874 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
14875 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
14876 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
14877 hash_find_entry, hash_rehash, hash_insert): Likewise.
14878 * src/conflicts.c (resolve_sr_conflict): Likewise.
14879 * src/lalr.c (set_goto_map, map_goto): Likewise.
14880 * src/nullable.c (nullable_compute): Likewise.
14881 * src/output.c (prepare_rules, token_definitions_output): Likewise.
14882 * src/reader.c (packgram, reader): Likewise.
14883 * src/state.c (state_new, state_free, state_transitions_set,
14884 state_reduction_find): Likewise.
14885 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
14886 symbol_pack): Likewise.
14887 * src/tables.c (conflict_row, pack_vector): Likewise.
14888 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
14889 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
14890 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
14891 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
14893 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
14894 (ARGMATCH_CONSTRAINT): New macro.
14895 (ARGMATCH_ASSERT): Use it.
14897 * src/system.h (verify): New macro.
14898 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
14899 rather than assert.
14900 * src/tables.c (tables_generate): Likewise.
14902 * src/struniq.c (struniq_assert): Now returns void, and aborts
14903 if the assertion is false.
14904 (struniq_assert_p): Remove.
14905 * src/struniq.h: Likewise.
14907 2002-11-18 Paul Eggert <eggert@twinsun.com>
14909 * data/glr.c (yygetLRActions): Replace `yyindex' with
14910 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
14911 This fixes the regression with Sun ONE Studio 7 cc that I reported in
14912 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
14914 2002-11-18 Akim Demaille <akim@epita.fr>
14916 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
14918 From Tim Van Holder.
14920 2002-11-17 Paul Eggert <eggert@twinsun.com>
14922 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
14923 to "SyntaxError" for consistency with my 2002-11-15 change.
14925 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
14926 not define to {}, since this breaks the common use of `YYDPRINTF
14927 ((...));' if a single statement is desired (e.g. before `else').
14928 Work around GCC warnings by surrounding corresponding calls with
14930 (yyhasResolvedValue): Remove unused function.
14931 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
14933 (yyreportSyntaxError): Renamed from yyreportParseError.
14934 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
14936 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
14937 extern when possible. Remove unused initializations.
14939 2002-11-16 Akim Demaille <akim@epita.fr>
14941 Augment the similarity between GLR and LALR traces.
14943 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
14944 (YY_REDUCE_PRINT): New.
14945 (yyparse): Use them.
14946 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
14948 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
14949 state reached after the reduction/recovery, since...
14950 (yyparse, yyprocessOneStack): Report the state we are entering in.
14952 2002-11-16 Akim Demaille <akim@epita.fr>
14954 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
14955 Add support for --trace=skeleton.
14956 * src/scan-skel.l: %option debug.
14957 Scan strings of non-@ or \n instead of character by character.
14958 (scan_skel): Handle trace_skeleton.
14960 (@output_parser_name@, @output_header_name@): ``Restore'' their
14961 support (used to be M4 macros).
14962 * data/yacc.c: Quote larger chunks, a la glr.c.
14963 * data/lalr1.cc: Likewise.
14964 The header guards are no longer available, so use some other
14965 string than `YYLSP_NEEDED'.
14967 2002-11-16 Akim Demaille <akim@epita.fr>
14969 Make the ``Printers and Destructors'' test more verbose, taking
14970 `yacc.c''s behavior as (possibly wrong) reference.
14972 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
14973 instead of fprint on stdout.
14974 Set and report the last_line of the symbols.
14975 Consistently display values and locations.
14977 2002-11-16 Paul Eggert <eggert@twinsun.com>
14979 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
14981 2002-11-15 Paul Eggert <eggert@twinsun.com>
14983 * tests/actions.at (Actions after errors): New test case.
14985 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
14986 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
14987 tests/action.at, tests/calc.at, tests/conflicts.at,
14988 tests/cxx-type.at, tests/regression.at:
14989 "parse error" -> "syntax error" for POSIX compatibility.
14990 "parsing stack overflow..." -> "parser stack overflow" so
14991 that code matches Bison documentation.
14993 2002-11-15 Akim Demaille <akim@epita.fr>
14995 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
14996 take two BRACED_CODE, not two string_content.
14997 Free the scanner's obstack when we are done.
14998 (code_content): New.
14999 * tests/calc.at: Adjust.
15000 * doc/bison.texinfo: Adjust.
15001 Also, make sure to include the `,' for these declarations.
15003 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
15005 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
15006 definition; avoids potential autoreconf problems.
15008 2002-11-15 Akim Demaille <akim@epita.fr>
15010 Always check the value returned by yyparse.
15012 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
15013 returned by yyparse.
15014 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
15016 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
15017 returned by yyparse.
15019 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
15021 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
15024 2002-11-14 Paul Eggert <eggert@twinsun.com>
15026 * src/output.c (output_skeleton): Call xfopen instead of
15027 duplicating xfopen's body.
15029 Fix bugs reported by Nelson H. F. Beebe in
15030 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
15032 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
15033 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
15034 Group compiler. Instead, use "$CC -E bar.c". Include the .h
15035 file twice in the grammar, as an extra check.
15037 * tests/input.at (Torturing the Scanner): Surround the
15038 backslash-newline tests with "#if 0", to make it less likely that
15039 we'll run into compiler bugs. Bring back solitary \ inside
15040 comment, but add a closing comment to work around HP C bug. Don't
15041 test backslash-newline in C character constant.
15043 2002-11-14 Akim Demaille <akim@epita.fr>
15045 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
15046 status of the compiler.
15047 Calling `exit 1' is no longer needed.
15048 Reported by Nelson H. F. Beebe.
15050 2002-11-14 Akim Demaille <akim@epita.fr>
15052 * tests/atlocal.in (CPPFLAGS): We have config.h.
15053 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
15055 * tests/actions.at, tests/calc.at, tests/conflicts.at,
15056 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
15057 * tests/regression.at, tests/torture.at: Use them for all the
15058 grammars that are to be compiled.
15059 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
15060 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
15061 * doc/bison.texinfo (GLR Parsers): Document `inline'.
15063 2002-11-14 Akim Demaille <akim@epita.fr>
15065 * doc/bison.texinfo: Various formatting changes (alignments in
15066 samples, additional @group/@end group, GCS in samples.
15067 Use @deffn instead of simple @table to define the directives,
15068 macros, variables etc.
15070 2002-11-13 Paul Eggert <eggert@twinsun.com>
15072 Fix some bugs reported by Albert Chin-A-Young in
15073 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
15075 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
15076 -o c"; the HP C compiler chatters during compilation.
15077 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
15078 * tests/headers.at (export YYLTYPE): Likewise.
15080 * tests/input.at (Torturing the Scanner): Remove lines containing
15081 solitary backslashes, as they tickle a bug in the HP C compiler.
15083 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
15084 comments, since they're not portable. Use GNU coding style.
15086 2002-11-13 Akim Demaille <akim@epita.fr>
15088 * data/yacc.c: Leave bigger chunks of quoted text.
15089 (YYDSYMPRINTF): New.
15090 Use it to report symbol activities.
15091 * data/glr.c (YYDSYMPRINTF): New.
15094 2002-11-12 Paul Eggert <eggert@twinsun.com>
15098 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
15099 (yyglrReduce): Return yyok, not 0.
15100 This should avoid the enumerated-type warnings reported
15101 by Nelson H. F. Beebe in
15102 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
15104 * lib/bbitset.h (BITSET_INLINE): Remove.
15105 * lib/bitset.h [! BITSET_INLINE]: Remove.
15106 (bitset_set, bitset_reset, bitset_test): Rename local vars
15107 to avoid shadowing warnings by GCC.
15109 * data/glr.c (inline): Remove #define. It's the user's
15110 responsibility to #define it away, just like 'const'.
15111 This fixes one of the bugs reported by Nelson H. F. Beebe in
15112 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
15114 * Makefile.maint (po-check): Scan .l and .y files instead of the
15115 .c and the .h files that they generate. This fixes the bug
15116 reported by Tim Van Holder in:
15117 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
15118 Look for N_ as well as for _. Try to avoid matching #define for
15120 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
15121 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
15122 * src/scan-gram.l: Revamp regular expressions so that " and '
15123 do not confuse xgettext.
15125 * src/struniq.h (struniq_new): Do not declare the return type
15126 to be 'const'; this violates the C standard.
15127 * src/struniq.c (struniq_new): Likewise.
15129 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
15131 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
15132 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
15135 2002-11-12 Akim Demaille <akim@epita.fr>
15137 * Makefile.maint: Sync with Autoconf:
15138 (local_updates): New.
15140 2002-11-12 Akim Demaille <akim@epita.fr>
15142 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
15144 2002-11-12 Akim Demaille <akim@epita.fr>
15146 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
15149 2002-11-12 Akim Demaille <akim@epita.fr>
15151 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
15154 2002-11-12 Akim Demaille <akim@epita.fr>
15156 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
15157 Use it to test the GLR parser.
15159 2002-11-12 Akim Demaille <akim@epita.fr>
15161 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
15163 * data/glr.c (yystos): New.
15164 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
15165 (YYDSYMPRINT): New.
15166 (yyval): Don't define it, it is handled via M4.
15167 (yyrecoverParseError): Free verbosely the discarded symbols.
15168 * data/yacc.c (yysymprint): Remove, rather...
15169 (b4_yysymprint_generate): invoke.
15170 * data/c.m4 (b4_yysymprint_generate): New.
15171 Accept pointers as arguments, as opposed to the version from
15173 (b4_yydestruct_generate): Likewise.
15174 * tests/cations.at (Printers and Destructors): Use Bison directives
15175 instead of CPP macros.
15176 Don't rely on internal details.
15178 2002-11-12 Akim Demaille <akim@epita.fr>
15180 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
15181 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
15182 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
15183 it against YYEMPTY and so forth), work on yytoken (i.e., set
15184 it to YYEMPTY etc.).
15185 (yydestruct): Replace with a b4_yydestruct_generate invocation.
15186 (b4_symbol_actions): Remove.
15187 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
15188 for 0, end-of-input.
15190 2002-11-12 Akim Demaille <akim@epita.fr>
15192 * doc/bison.texinfo (Destructor Decl): New.
15194 2002-11-12 Akim Demaille <akim@epita.fr>
15196 * src/tables.c (tables_generate): Use free for pointers that
15197 cannot be NULL, not XFREE.
15198 (pack_vector): Use assert, not fatal, for bound violations.
15199 * src/state.c (state_new): Likewise.
15200 * src/reader.c (reader): Likewise.
15201 * src/lalr.c (set_goto_map): Likewise.
15202 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
15205 2002-11-12 Akim Demaille <akim@epita.fr>
15207 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
15209 * src/scan-gram.l (last_string): Is global to the file, not to
15211 * src/parse-gram.y (input): Don't append the epilogue here,
15212 (epilogue.opt): do it here, and free the scanner's obstack.
15213 * src/reader.c (epilogue_set): Rename as...
15214 (epilogue_augment): this.
15215 * data/c.m4 (b4_epilogue): Defaults to empty.
15217 2002-11-12 Akim Demaille <akim@epita.fr>
15219 * src/getargs.c (long_options): Remove duplicates.
15220 * src/vmsgetargs.c, src/build.com, src/bison.cld, src/vmshlp.mar:
15222 * doc/bison.rnh: Remove.
15223 * doc/bison.texinfo (VMS Invocation): Remove.
15225 2002-11-12 Akim Demaille <akim@epita.fr>
15227 * src/struniq.h, src/struniq.c (struniq_t): Is const.
15228 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
15230 Use struniq for symbols.
15232 * src/symtab.h (symbol_t): The tag member is a struniq.
15233 (symbol_type_set): Adjust.
15234 * src/symtab.c (symbol_new): Takes a struniq.
15235 (symbol_free): Don't free the tag member.
15236 (hash_compare_symbol_t, hash_symbol_t): Rename as...
15237 (hash_compare_symbol, hash_symbol): these.
15238 Use the fact that tags as struniqs.
15239 (symbol_get): Use struniq_new.
15240 * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get):
15242 * src/reader.h (merger_list, grammar_currentmerge_set): The name
15243 and type members are struniqs.
15244 * src/reader.c (get_merge_function)
15245 (grammar_current_rule_merge_set): Adjust.
15246 (TYPE, current_type): Are struniq.
15248 Use struniq for file names.
15250 * src/files.h, src/files.c (infile): Split into...
15251 (grammar_file, current_file): these.
15252 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.

15256 * src/main.c (main): Call struniqs_new early enough to use it for
15258 Don't free the input file name.
15260 2002-11-12 Akim Demaille <akim@epita.fr>
15262 * src/symtab.c (symbol_free): Remove dead deactivated code:

15273 2002-11-11 Paul Eggert <eggert@twinsun.com>
15275 Revamp to fix many (but not all) of the C- and M4-related quoting
15276 problems. Among other things, this fixes the Bison bug reported
15277 by Jan Hubicka when processing the Bash grammar; see:
15278 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
15280 Use new @ escapes consistently. Represent brackets with @{ and @}
15281 rather than @<:@ and @:>@, since this works a bit better with dumb
15282 editors like vi. Represent @ with @@, since @ is now consistently
15283 an escape. Use @oline@ and @ofile@ rather than __oline__ and
15284 __ofile__, to avoid unexpected expansions. Similarly, use @output
15285 rather than #output.
15287 * data/c.m4 (b4_copyright): Omit file name from comment, since
15288 the file name could contain "*/".
15289 (b4_synclines_flag): Don't quote the 2nd argument; it should already
15290 be quoted. All uses changed.
15292 * data/glr.c: Use new @ escapes consistently.
15293 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
15294 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
15295 Remove, since they couldn't handle arbitrary characters in file
15297 * data/lalr1.cc: Likewise.
15298 * data/yacc.c: Likewise.
15300 * src/files.c (output_infix): Remove; all uses removed.
15301 * src/files.h: Likewise.
15303 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
15304 mishandled funny characters in file names, and anyway it isn't
15306 * data/yacc.c: Likewise.
15307 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
15309 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
15310 * data/yacc.c: Likewise.
15312 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
15314 (muscle_init): Quote filename as a C string.
15315 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
15316 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
15317 * src/output.c (escaped_file_name_output): New function.
15318 (prepare_symbols): Quote tokens for M4.
15319 (prepare): Don't insert output_infix, output_prefix,
15320 output_parser_name, output_header_name; this is now down by scan-skel.
15321 Insert skeleton as a C string.
15323 * src/output.c (user_actions_output, symbol_destructors_output,
15324 symbol_printers_output): Quote filenames for C and M4.
15325 * src/reader.c (prologue_augment, epilogue_set): Likewise.
15327 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
15328 escapes other than \\ and \'; this simplifies the code.
15329 (<SC_STRING>): Likewise, for \\ and \".
15330 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
15331 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
15332 Use new escapes @{ and @} for [ and ].
15334 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
15335 them with auto vars.
15336 Switch to new escape scheme, where @ is the escape character uniformly.
15337 Abort if a stray escape character is found. Avoid unbounded input
15338 buffer when parsing non-escaped text.
15340 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
15341 __oline__, #output, $@, and @{ do not have unintended meanings.
15343 2002-11-09 Paul Eggert <eggert@twinsun.com>
15345 Fix the test failure due to GCC warnings described in
15346 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
15347 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
15348 evaluate to 0 if it's impossible for NINF to be in the respective
15350 (yygetLRActions, yyrecoverParseError): Use them.
15352 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
15353 counted in the token inserted at end of file. Now takes
15354 location_t *, not location_t, so that the location can be
15355 adjusted. All uses changed.
15357 * tests/regression.at (Invalid inputs): Adjust wording in
15358 diagnostic to match the new behavior.
15360 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
15361 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
15362 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
15363 abort ();'. This reduces the runtime of the "Many lookaheads"
15364 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
15367 2002-11-07 Paul Eggert <eggert@twinsun.com>
15369 * src/parse-gram.y (CHARACTER): Remove unused token.
15372 * src/scan-gram.l: Remove stack option. We no longer use the
15373 stack, since the stack was never deeper than 1; instead, use the
15374 new auto var c_context to record the stacked value.
15376 Remove nounput option. At an unexpected end of file, we now unput
15377 the minimal input necessary to end cleanly; this simplifies the
15380 Avoid unbounded token sizes where this is easy.
15382 (unexpected_end_of_file): New function.
15383 Use it to systematize the error message on unexpected EOF.
15384 (last-string): Now auto, not static.

15391 2002-11-07 Akim Demaille <akim@epita.fr>
15393 Let yyerror always receive the msg as last argument, so that
15394 yyerror can be variadic.
15396 * data/yacc.c (b4_yyerror_args): New.
15397 Use it when calling yyerror.
15398 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

15448 * src/scan-gram.l: Use more accurate diagnostics, e.g.
15449 "integer out of range" rather than "invalid value".
15450 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
15453 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
15454 Also, remove one static variable in the scanner.
15456 * src/scan-gram.l (braces_level): Now auto, not static.
15457 Initialize to zero if the compiler is being picky.
15458 (INITIAL): Clear braces_level instead of incrementing it.
15459 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,

15464 2002-11-05 Akim Demaille <akim@epita.fr>
15466 * src/scan-gram.l: When it starts with `%', complain about the
15467 whole directive, not just that `invalid character: %'.
15469 2002-11-04 Akim Demaille <akim@epita.fr>
15471 * Makefile.maint: Update from Autoconf.
15472 (update, cvs-update, po-update, do-po-update): New.

15493 2002-11-03 Paul Eggert <eggert@twinsun.com>
15495 * src/reader.c (get_merge_function, grammar_current_rule_check):
15496 Use consistent diagnostics for reporting type name clashes.
15497 Quote the types with <>, for consistency with Yacc.
15498 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
15500 2002-11-03 Akim Demaille <akim@epita.fr>
15502 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
15504 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.

15514 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
15515 (yyreportAmbiguity): When using a pure parser, also need
15516 the location, and the parse-params.
15518 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
15519 When using a pure parser, also need the parse-params.
15521 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
15522 (%pure-parser + %parse-param) LALR and GLR parsers.
15523 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
15524 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,

15531 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
15532 (Error Reporting): Adjust to these new directives.
15533 Document %error-verbose, deprecate YYERROR_VERBOSE.
15535 2002-11-03 Akim Demaille <akim@epita.fr>
15537 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
15538 AT_CHECK_CALC_GLR invocations to use % directives, instead of
15539 command line options.
15540 * tests/cxx-type.at: Formatting changes.
15542 2002-11-03 Paul Eggert <eggert@twinsun.com>
15544 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
15545 to count columns correctly, and to check for invalid inputs.
15547 Use mbsnwidth to count columns correctly. Account for tabs, too.
15548 Include mbswidth.h.
15549 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
15550 (extend_location): New function.
15551 (YY_LINES): Remove.
15553 Handle CRLF in C code rather than in Lex code.

15560 Handle backslash-newline correctly in C code.
15561 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
15562 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
15564 (tag, splice): New EREs. Do not allow NUL or newline in tags.
15565 Use {splice} wherever C allows backslash-newline.
15566 YY_STEP after space, newline, vertical-tab.
15567 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
15569 (letter, id): Don't assume ASCII; e.g., spell out a-z.
15571 ({int}, handle_action_dollar, handle_action_at): Check for integer
15574 (YY_STEP): Omit trailing semicolon, so that it's more like C.
15576 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
15577 as well as \000. Check for UCHAR_MAX, not 255.
15578 Allow \x with an arbitrary positive number of digits, as in C.
15579 Check for overflow here.
15580 Allow \? and UCNs, for compatibility with C.
15582 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
15583 with quote slot used by complain_at.
15585 * tests/input.at: Add tests for backslash-newline, m4 quotes
15586 in symbols, long literals, and funny escapes in strings.

15594 * doc/bison.texinfo (Grammar Outline): Document // comments.
15595 (Symbols): Document that trigraphs have no special meaning in Bison,
15596 nor is backslash-newline allowed.

15602 2002-11-02 Paul Eggert <eggert@twinsun.com>
15604 * src/reader.c: Don't include quote.h; not needed.
15605 (get_merge_function): Reword warning to be consistent with
15606 type clash diagnostic in grammar_current_rule_check.
15608 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
15609 bug in trigraph handling.
15611 * src/output.c (prepare_symbols): When printing token names,
15612 escape "[" as "@<:@" and likewise for "]".
15614 * src/system.h (errno): Remove declaration, as we are now
15615 assuming C89 or better, and C89 guarantees errno.
15617 2002-10-30 Paul Eggert <eggert@twinsun.com>
15619 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
15620 Check for close failures.
15621 * src/files.h (xfclose): Return void, not int, since it always
15623 * src/files.c (xfclose): Likewise. Report I/O error if ferror
15625 * src/output.c (output_skeleton): Use xfclose rather than fclose
15626 and ferror. xfclose now checks ferror.
15628 * data/glr.c (YYLEFTMOST_STATE): Remove.
15629 (yyreportTree): Use a stack-based leftmost state. This avoids
15630 our continuing battles with bogus warnings about initializers.
15632 2002-10-30 Akim Demaille <akim@epita.fr>
15634 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

15639 * tests/glr-regr1.at: New test for reported regressions.
15640 * tests/testsuite.at: Add glr-regr1.at test.

15647 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
15648 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
15649 we use malloc. Don't assume 'A' through 'Z' are contiguous.
15650 Don't assume strdup exists; POSIX says its an XSI extension.
15651 Check for buffer overflow on input.
15653 2002-10-24 Akim Demaille <akim@epita.fr>
15655 * src/output.c (output_skeleton): Don't disable M4sugar comments
15656 too soon: it results in comments being expanded.
15657 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
15660 2002-10-24 Akim Demaille <akim@epita.fr>
15662 * data/yacc.c (m4_int_type): New.
15663 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
15664 char' as only yacc.c wants K&R portability.
15665 * data/glr.c (yysigned_char): Remove.
15666 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
15667 Reported by Quoc Peyrot.
15669 2002-10-23 Paul Eggert <eggert@twinsun.com>
15671 * src/main.c (main): With --trace=time, report times even if a
15672 non-fatal error occurs. Formerly, the times were reported in some
15673 such cases but not in others.
15674 * src/reader.c (reader): Just return if a complaint has been issued,
15675 instead of exiting, so that 'main' can report times.
15677 2002-10-22 Akim Demaille <akim@epita.fr>
15679 * src/system.h: Include sys/types.
15680 Reported by Bert Deknuydt.
15682 2002-10-23 Paul Eggert <eggert@twinsun.com>
15684 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
15685 Suggested by Art Haas.
15687 2002-10-22 Paul Eggert <eggert@twinsun.com>
15689 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
15690 decl; not needed any more.
15691 * src/main.c (main): Use return to exit, undoing yesterday's change.
15692 The last OS that we could find where this wouldn't work is
15693 SunOS 3.5, and that's too old to worry about now.
15695 * data/glr.c (struct yyltype): Define members even when not
15696 doing locations. This is more consistent with yacc.c, and it
15697 works around the following bug reports:
15698 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
15699 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
15701 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
15702 @acronym consistently. Standardize on "Yacc" instead of "YACC",
15703 "Algol" instead of "ALGOL". Give a bit more history about BNF.
15705 2002-10-22 Akim Demaille <akim@epita.fr>
15707 * data/README: New.
15709 2002-10-21 Paul Eggert <eggert@twinsun.com>
15711 Be consistent about 'bool'; the old code used an enum in one
15712 module and an int in another, and this violates the C standard.
15713 * m4/stdbool.m4: New file, from coreutils 4.5.3.
15714 * configure.ac (AC_HEADER_STDBOOL): Add.
15715 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
15716 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
15717 * src/symtab.c (hash_compare_symbol_t): Likewise.
15718 * src/system.h (bool, false, true): Use a definition consistent
15719 with ../lib/hash.c. All uses changed.
15721 * src/complain.c (warning_issued): Renamed from warn_message_count,
15722 so that we needn't worry about integer overflow (!).
15723 Now of type bool. All uses changed.
15724 (complaint_issued): Renamed from complain_message_count; likewise.
15726 * src/main.c (main): Use exit to exit with failure.
15728 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
15729 rather than 1 and 0.
15730 * src/main.c (main): Likewise.
15731 * src/getargs.c (getargs): Likewise.
15732 * src/reader.c (reader): Likewise.
15734 * src/getarg.c (getargs): Remove duplicate code for
15735 "Try `bison --help'".
15737 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
15738 What was that "2" for?
15740 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
15741 * src/getargs.c (usage): Likewise.
15743 * src/getargs.c (getargs): When there are too few operands, report
15744 the last one. When there are too many, report the first extra
15745 one. This is how diffutils does it.
15747 2002-10-20 Paul Eggert <eggert@twinsun.com>
15749 Remove K&R vestiges.
15750 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
15751 * src/complain.c (VA_START): Remove. Assume prototypes.
15752 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
15753 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
15754 fatal): Assume prototypes.
15755 * src/complain.h: Assume prototypes.
15756 * src/system.h (PARAMS): Remove.
15757 Include <limits.h> unconditionally, since it's guaranteeed even
15758 for a freestanding C89 compiler.
15759 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
15760 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
15762 2002-10-20 Akim Demaille <akim@epita.fr>
15764 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.

15769 (yy_reduce_print): New.
15770 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.

15775 arguments and output `void'.

15777 (b4_c_function_def): this.
15778 (b4_c_function_decl, b4_c_ansi_function_def)
15779 (b4_c_ansi_function_decl): New.
15780 Change the interpretation of the arguments: before `int, foo', now
15782 * data/yacc.c (yyparse): Prototype and define thanks to these.
15783 Adjust b4_c_function_def uses.
15784 * data/glr.c (yyparse): Likewise, but ANSI only.
15786 2002-10-20 Akim Demaille <akim@epita.fr>
15788 * src/output.c (prepare): Move the definition of `tokens_number',
15789 `nterms_number', `undef_token_number', `user_token_number_max'
15791 (prepare_tokens): Here.
15792 (prepare_tokens): Rename as...
15793 (prepare_symbols): this.
15794 (prepare): Move the definition of `rules_number' to...
15795 (prepare_rules): here.
15796 (prepare): Move the definition of `last', `final_state_number',

15798 (prepare_states): here.
15799 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
15801 2002-10-20 Akim Demaille <akim@epita.fr>
15803 * src/tables.h, src/tables.c, src/output.c: Comment changes.
15805 2002-10-20 Akim Demaille <akim@epita.fr>
15807 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
15810 2002-10-20 Akim Demaille <akim@epita.fr>
15812 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
15813 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
15815 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
15817 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
15818 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
15821 2002-10-19 Paul Eggert <eggert@twinsun.com>
15823 Do not create a temporary file, as that involves security and
15824 cleanup headaches. Instead, use a pair of pipes.
15825 Derived from a suggestion by Florian Krohm.
15826 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
15827 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.

15837 (output_skeleton): Use pipe rather than temporary file for m4 input.
15838 Check that m4sugar.m4 is readable, to avoid deadlock.
15839 Check for pipe I/O error.
15840 * src/scan-skel.l (readpipe): Remove decl.
15841 (scan_skel): New function, to be used in place of m4_invoke.
15842 Read from stream rather than file.
15844 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
15845 float, as this generates a warning on Solaris 8 + GCC 3.2 with
15846 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
15847 this generates a more-accurate value anyway.
15849 * lib/timevar.c (timervar_accumulate): Rename locals to
15850 avoid confusion with similarly-named more-global.
15851 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
15853 * src/output.c (prepare): Use xstrdup to convert char const *
15854 to char *, to avoid GCC warning.
15856 2002-10-19 Akim Demaille <akim@epita.fr>
15858 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
15859 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
15860 Use them to have `calc.y' ready for %pure-parser.
15861 * data/yacc.c (YYLEX): Pass a yylex return type to
15862 b4_c_function_call.
15864 2002-10-19 Akim Demaille <akim@epita.fr>
15866 Prototype support of %lex-param and %parse-param.
15868 * src/parse-gram.y: Add the definition of the %lex-param and
15869 %parse-param tokens, plus their rules.
15870 Drop the `_' version of %glr-parser.
15872 * src/scan-gram.l (INITIAL): Scan them.
15873 * src/muscle_tab.c: Comment changes.
15874 (muscle_insert, muscle_find): Rename `pair' as `probe'.
15875 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
15876 (muscle_entry_s): The `value' member is no longer const.
15877 Adjust all dependencies.
15878 * src/muscle_tab.c (muscle_init): Adjust: use
15879 MUSCLE_INSERT_STRING.
15880 Initialize the obstack earlier.
15881 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
15882 (muscle_pair_list_grow): New.
15883 * data/c.m4 (b4_c_function_call, b4_c_args): New.
15884 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
15885 * tests/calc.at: Use %locations, not --locations.
15886 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
15888 2002-10-19 Akim Demaille <akim@epita.fr>
15890 * src/getargs.c (usage): Take status as argument and exit
15892 Report the traditional `Try ... --help' message when status != 0.
15893 (usage, version): Don't take a FILE * as arg, it is pointless.
15894 (getargs): When there is an incorrect number of arguments, make it
15895 an error, and report it GNUlically thanks to `usage ()'.
15897 2002-10-18 Paul Eggert <eggert@twinsun.com>
15899 * data/glr.c (yyreportParseError): Don't assume that sprintf
15900 yields the length of the printed string, as this is not true
15901 on SunOS 4.1.4. Reported by Peter Klein.
15903 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
15904 * tests/conflicts.at (%nonassoc and eof): Likewise.
15905 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
15907 2002-10-17 Akim Demaille <akim@epita.fr>
15909 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
15910 * src/getargs.c (trace_types, trace_args): Adjust.
15911 * src/reader.c (grammar_current_rule_prec_set)
15912 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
15913 Standardize error messages.
15914 And s/@prec/%prec/!
15915 (reader): Use trace_flag to enable scanner/parser debugging,
15916 instead of an adhoc scheme.
15917 * src/scan-gram.l: Remove trailing debugging code.
15919 2002-10-16 Paul Eggert <eggert@twinsun.com>
15921 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
15924 * NEWS: Officially drop support for building Bison with K&R C,
15925 since it didn't work anyway and it's not worth worrying about.
15926 * Makefile.maint (wget_files): Remove ansi2knr.c.
15927 (ansi2knr.c-url_prefix): Remove.
15928 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
15929 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
15930 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
15932 2002-10-15 Paul Eggert <eggert@twinsun.com>
15934 Stop using the "enum_" trick for K&R-style function definitions;
15935 it confused me, and I was the author! Instead, assume that people
15936 who want to use K&R C compilers (when using these modules in GCC,
15937 perhaps?) will run ansi2knr.
15939 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
15940 All uses of "enum_" changed to "enum ".
15941 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
15942 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
15944 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

15952 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
15953 Use function prototypes; this removes the need for declaring
15954 static functions simply to provide their prototypes.
15955 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

16012 2002-10-14 Akim Demaille <akim@epita.fr>
16014 * tests/Makefile.am (maintainer-check-posix): New.
16016 2002-10-14 Akim Demaille <akim@epita.fr>
16018 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
16021 2002-10-14 Akim Demaille <akim@epita.fr>
16023 * src/tables.c (table_ninf_remap): base -> tab.
16024 Reported by Matt Rosing.
16026 2002-10-14 Paul Eggert <eggert@twinsun.com>
16028 * tests/action.at, tests/calc.at, tests/conflicts.at,
16029 tests/cxx-type.at, tests/headers.at, tests/input.at,
16030 tests/regression.at, tests/synclines.at, tests/torture.at:
16031 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
16032 so that the tests still work even if POSIXLY_CORRECT is set.
16033 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
16035 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
16036 for portability to K&R hosts. Fix typo: signed char is guaranteed
16037 only to 127, not to 128.
16038 * data/glr.c (yysigned_char): New type.
16039 * data/yacc.c (yysigned_char): Likewise.
16040 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
16042 2002-10-13 Paul Eggert <eggert@twinsun.com>
16044 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
16045 true due to limited range of data type" warning from GCC.
16047 * data/c.m4 (b4_token_defines): Protect against double-inclusion
16048 by wrapping enum yytokentype's definition inside #ifndef
16049 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
16051 2002-10-13 Akim Demaille <akim@epita.fr>
16053 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
16054 Un yy- yyrhs to avoid the name clash with the global YYRHS.
16056 2002-10-13 Akim Demaille <akim@epita.fr>
16058 * Makefile.maint: Update from Autoconf 2.54.
16059 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
16061 2002-10-13 Akim Demaille <akim@epita.fr>
16063 * src/print.c (print_state): Separate the list of solved conflicts
16064 from the other items.
16065 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
16067 2002-10-13 Akim Demaille <akim@epita.fr>
16069 Let nondeterministic skeletons be usable with deterministic
16072 With the patch, GAWK compiled by GCC without -O2 passes its test
16073 suite using a GLR parser driven by LALR tables. It fails with -O2
16074 because `struct stat' gives two different answers on my machine:
16075 88 (definition of an auto var) and later 96 (memset on this var).
16076 Hence the stack is badly corrumpted. The headers inclusion is to
16077 blame: if I move the awk.h inclusion before GLR's system header
16078 inclusion, the two struct stat have the same size.
16080 * src/tables.c (pack_table): Always create conflict_table.
16081 (token_actions): Always create conflict_list.
16082 * data/glr.c (YYFLAG): Remove, unused.
16084 2002-10-13 Akim Demaille <akim@epita.fr>
16086 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
16088 (VALGRIND, GXX): New.
16089 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
16090 * tests/bison.in: Run $PREBISON a pre-command.
16091 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
16092 (maintainer-check-g++): New.
16093 * Makefile.am (maintainer-check): New.
16095 2002-10-13 Akim Demaille <akim@epita.fr>
16097 * data/glr.c: Formatting changes.
16098 Tweak some trace messages to match yacc.c's.
16100 2002-10-13 Akim Demaille <akim@epita.fr>
16102 GLR parsers sometimes raise parse errors instead of performing the
16104 Reported by Charles-Henry de Boysson.
16106 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
16107 check the length of the traces when %glr.
16108 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
16110 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
16112 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
16113 (yyltype): Remove the yy prefix from the member names.
16114 (yytable): Complete its comment.
16115 (yygetLRActions): Map error action number from YYTABLE from
16117 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
16118 (which was a bug: it should have been YYTABEL_NINF, and yet it was
16119 not satisfying as we could compare an YYACTION computed from
16120 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
16121 only value for error actions.
16122 (yyreportParseError): In verbose parse error messages, don't issue
16123 `error' in the list of expected tokens.
16124 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
16125 next action to perform to match glr.c's decoding.
16126 (yytable): Complete its comment.
16128 2002-10-13 Paul Eggert <eggert@twinsun.com>
16130 Fix problem reported by Henrik Grubbstroem in
16131 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
16132 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
16133 because the Bison parser reads the second action before reducing
16135 * src/scan-gram.l (rule_length): New static var.
16136 Use it to keep track of the rule length in the scanner, since
16137 we can't expect the parser to be in lock-step sync with the scanner.
16138 (handle_action_dollar, handle_action_at): Use this var.
16139 * tests/actions.at (Exotic Dollars): Test for the problem.
16141 2002-10-12 Paul Eggert <eggert@twinsun.com>
16143 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
16144 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
16145 Include <sys/time.h> when checking for clock_t and struct tms.
16146 Use same include order as source.
16147 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
16148 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
16150 * lib/timevar.c: Update copyright date and clarify comments.
16151 (get_time) [IN_GCC]: Keep the GCC version for reference.
16153 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
16154 GCC version as of today, then merge Bison's changes.
16155 Change "GCC" to "Bison" in copyright notice. timevar.def's
16156 author is Akim, so change that too.
16158 * src/reader.c (grammar_current_rule_check):
16159 Don't worry about the default action if $$ is untyped.
16160 Prevents bogus warnings reported by Jim Gifford in
16161 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
16163 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
16164 * data/glr.c, data/lalr1.cc, data/yacc.c:
16165 Output token definitions before the first part of user declarations.
16166 Fixes compatibility problem reported by Jim Gifford for kbd in
16167 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
16169 2002-10-11 Paul Eggert <eggert@twinsun.com>
16171 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
16172 (yyparse): here. This undoes some of the 2002-07-25 change.
16173 Compatibility problem reported by Ralf S. Engelschall with
16174 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

16193 * lib/lbitset.c: Likewise.
16195 * lib/abitset.c (abitset_bytes): Return a size that is aligned

16198 properly aligned for the whole union.

16236 type enum_bitset_opts, to conform to the C Standard, and similarly
16237 for enum_bitset_type.
16238 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
16239 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
16241 Do not use "struct bitset_struct" to mean different things in
16242 different modules. Not only is this confusing, it violates
16243 the C Standard, which requires that structure types in different
16244 modules must be compatible if one is to be passed to the other.
16245 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
16246 All instances of "struct bitset_struct *" replaced with "bitset".
16247 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
16248 (union bitset_union, struct abitset_struct, struct ebitset_struct,
16249 struct lbitset_struct, struct bitset_stats_struct): New types.

16255 struct bitset_struct): Remove.
16256 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
16257 bitset_struct): Remove.
16258 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
16261 Do not call a function of type T using a call that assumes the
16262 function is of a different type U. Standard C requires that a
16263 function must be called with a type that is compatible with its
16265 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
16267 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
16269 * lib/ebitset.c (PFV): Remove.

16286 Use offsetof, for simplicity.
16288 2002-10-06 Paul Eggert <eggert@twinsun.com>
16290 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
16291 the same width as int. This reapplies a hunk of the 2002-08-12 patch
16292 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
16293 which was inadvertently undone by the 2002-09-30 patch.
16294 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
16295 the same width as int.
16297 2002-10-04 Paul Eggert <eggert@twinsun.com>

16303 * doc/bison.texinfo: Minor spelling, grammar, and white space
16305 (Symbols): Mention that any negative value returned from yylex
16306 signifies end-of-input. Warn about negative chars. Mention
16307 the portable Standard C character set.

16319 * src/reader.c (reader): Use it.
16321 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
16322 POSIX 1003.1-2001 has removed fgrep.
16324 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>

16399 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
16400 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

16597 PROTOTYPES to check for prototypes, and "defined __STDC__" to

16646 * src/main.c (main): Cast result of bindtextdomain and textdomain
16647 to void, to avoid a GCC warning when --disable-nls is in effect.
16649 * src/scan-gram.l: Use strings rather than escapes when possible,
16650 to minimize the number of warnings from xgettext.
16651 (handle_action_dollar, handle_action_at): Don't use isdigit,
16652 as it mishandles negative chars and it may not work as expected
16653 outside the C locale.
16655 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
16656 this is a GCC extension and is not portable to other compilers.

16670 exit status as failure, not just exit status 1. Sun C exits
16671 with status 2 sometimes.

16674 Use it for the two large tests.
16676 2002-08-02 Akim Demaille <akim@epita.fr>
16678 * src/conflicts.c (conflicts_output): Don't output rules never
16679 reduced here, since anyway that computation doesn't work.

16895 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
16896 for the time being: %locations ought to provide it to yyerror.

18871 was used solely to set the precedence of the last rule...
18873 2002-04-07 Akim Demaille <akim@epita.fr>
18875 * data/bison.c++, data/bison.simple: Don't output the current file
18876 name in #line, to avoid useless diffs between two identical
18877 outputs under different names.

18881 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

19100 * src/closure.c (firsts): Now, also a bitset.
19101 Adjust all dependencies.
19102 (varsetsize): Remove, now unused.
19103 * src/warshall.h, src/warshall.c: Now work on arrays of bitsets.
19105 2002-03-04 Akim Demaille <akim@epita.fr>
19107 * src/print.c: Convert to use bitset.h, not hand coded iterations
19110 2002-03-04 Akim Demaille <akim@epita.fr>
19112 * src/reduce.c: Convert to use bitset.h, not hand coded BSet.
19114 2002-03-04 Akim Demaille <akim@epita.fr>
19116 * src/closure.c (ruleset): Be a bitset.
19117 (rulesetsize): Remove.
19119 2002-03-04 Akim Demaille <akim@epita.fr>
19121 * lib/bitset-int.h, lib/bitset.c, lib/bitset.h, lib/bitsetv.c,

19123 * lib/lbitset.h, lib/sbitset.c, lib/sbitset.h: New.
19124 * src/closure.c (fderives): Be an array of bitsets.
19126 2002-02-28 Robert Anisko <robert@lrde.epita.fr>
19128 * data/bison.c++: Merge the two generated headers. Insert a copyright
19129 notice in each output file.
19131 2002-02-28 Akim Demaille <akim@epita.fr>
19133 * data/bison.c++: Copy the prologue of bison.simple to fetch
19134 useful M4 definitions, such as b4_header_guard.
19136 2002-02-25 Akim Demaille <akim@epita.fr>
19138 * src/getargs.c (version): Give the name of the authors, and use a
19139 translator friendly scheme for the bgr
19142 2002-02-25 Akim Demaille <akim@epita.fr>
19144 * src/output.c (header_output): Remove, now handled completely via
19147 2002-02-25 Akim Demaille <akim@epita.fr>
19149 * m4/m4.m4: New, from CVS Autoconf.
19150 * configure.in: Invoke it.
19151 * src/output.c (output_skeleton): Use its result instead of the
19154 2002-02-25 Akim Demaille <akim@epita.fr>
19156 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
19158 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
19159 * src/output.c (output_skeleton): Use mkstemp to create a real
19161 Move the filling of `skeleton' and its muscle to...
19163 (output): Move the definition of the prologue muscle to...
19165 * src/system.h (DEFAULT_TMPDIR): New.
19167 2002-02-14 Paul Eggert <eggert@twinsun.com>
19169 Remove the support for C++ namespace cleanliness; it was
19170 causing more problems than it was curing, since it didn't work
19171 properly on some nonstandard C++ compilers. This can wait
19172 for a proper C++ parser.
19174 * NEWS: Document this.
19175 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
19176 of C++, as it's treated like C now.
19177 * src/bison.simple (YYSTD): Remove.
19178 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
19179 Treat C++ just like Standard C instead of trying to support
19180 namespace cleanliness.
19182 2002-02-14 Akim Demaille <akim@epita.fr>
19184 * tests/regression.at (else): Adjust to Andreas' change.
19186 2002-02-14 Akim Demaille <akim@epita.fr>
19188 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
19190 2002-02-13 Andreas Schwab <schwab@suse.de>
19192 * src/output.c (output_rule_data): Don't output NULL, it might
19193 not be defined yet.
19195 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
19197 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
19198 (Copyright notice): Update.
19200 2002-02-11 Akim Demaille <akim@epita.fr>
19202 * tests/regression.at (%nonassoc and eof): Don't include
19203 nonportable headers.
19205 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
19207 * data/bison.c++: Correct error recovery. Make the user able to
19208 initialize the starting location.
19210 2002-02-07 Akim Demaille <akim@epita.fr>
19212 * tests/input.at: New.
19214 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
19216 * data/bison.c++: Replace some direct m4 expansions by constants. Be
19217 more consistent when naming methods and variables. Put preprocessor
19218 directives around tables only needed for debugging.
19220 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
19222 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
19224 (yy::b4_name::parse): Use print_.
19226 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
19228 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
19230 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
19232 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
19234 (yy::b4_name::parse): Build verbose error messages, and use error_.
19236 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
19238 * data/bison.c++: Fix m4 quoting in comments.
19240 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
19242 * data/bison.c++: Adjust the parser code. Fix some muscles that were
19243 not expanded by m4.
19245 2002-02-05 Akim Demaille <akim@epita.fr>
19247 * data/bison.c++: Adjust to the M4 back end.
19248 More is certainly needed.
19250 2002-02-05 Akim Demaille <akim@epita.fr>
19252 Give a try to M4 as a back end.
19254 * lib/readpipe.c: New, from wdiff.
19255 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
19257 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
19258 specific values. Now it is m4 that performs the lookup.
19259 * src/parse-skel.y: Remove.
19260 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
19261 * src/output.c (actions_output, guards_output)
19262 (token_definitions_output): No longer keeps track of the output
19263 line number, hence remove the second argument.
19264 (guards_output): Check against the guard member of a rule, not the
19267 (output_skeleton): Don't look for the skeleton location, let m4 do
19269 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
19271 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
19272 (prepare): Given that for the time being changesyntax is not
19273 usable in M4, rename the muscles using `-' to `_'.
19274 Define `defines_flag', `output_parser_name' and `output_header_name'.
19275 * src/output.h (actions_output, guards_output)
19276 (token_definitions_output): Adjust prototypes.
19277 * src/scan-skel.l: Instead of scanning the skeletons, it now
19278 processes the output of m4: `__oline__' and `#output'.
19279 * data/bison.simple: Adjust to be used by M4(sugar).
19280 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
19282 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
19283 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
19284 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
19285 shamelessly stolen from CVS Autoconf.
19287 2002-02-05 Akim Demaille <akim@epita.fr>
19289 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
19290 * configure.in: Check for the declarations of free and malloc.
19291 * src/muscle_tab.c: Adjust.
19293 2002-02-05 Akim Demaille <akim@epita.fr>
19295 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
19296 which have no values.
19298 2002-02-05 Akim Demaille <akim@epita.fr>
19300 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
19303 2002-01-29 Paul Eggert <eggert@twinsun.com>
19305 * src/bison.simple (YYSIZE_T): Do not define merely because
19306 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
19307 On some platforms, <alloca.h> does not declare YYSTD (size_t).
19309 2002-01-27 Akim Demaille <akim@epita.fr>
19311 Fix `%nonassoc and eof'.
19313 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
19314 which were not properly copied! Replace
19315 memcpy (res->errs, src->errs, src->nerrs);
19317 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
19319 * tests/regression.at (%nonassoc and eof): Adjust to newest
19320 Autotest: `.' is not in the PATH.
19322 2002-01-27 Akim Demaille <akim@epita.fr>
19324 * tests/sets.at (AT_EXTRACT_SETS): New.
19325 (Nullable): Use it.
19328 2002-01-26 Akim Demaille <akim@epita.fr>
19330 * tests/actions.at, tests/calc.at, tests/headers.at,
19331 * tests/torture.at: Adjust to the newest Autotest which no longer
19332 forces `.' in the PATH.
19334 2002-01-25 Akim Demaille <akim@epita.fr>
19336 * tests/regression.at (%nonassoc and eof): New.
19337 Suggested by Robert Anisko.
19339 2002-01-24 Akim Demaille <akim@epita.fr>
19341 Bison dumps core when trying to complain about broken input files.
19342 Reported by Cris van Pelt.
19344 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
19345 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
19347 (Invalid inputs): Strengthen: exercise parse_percent_token.
19349 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
19351 * src/Makefile.am: Add bison.c++.
19352 * src/bison.c++: New skeleton.
19354 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
19358 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
19360 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
19362 2002-01-20 Marc Autret <marc@gnu.org>
19364 * src/files.c (compute_output_file_names): Fix
19366 2002-01-20 Marc Autret <marc@gnu.org>
19368 * tests/output.at: New test.
19369 * src/files.c (compute_base_names): Don't map extensions when
19370 the YACC flag is set, use defaults.
19371 Reported by Evgeny Stambulchik.
19373 2002-01-20 Marc Autret <marc@gnu.org>
19375 * src/system.h: Need to define __attribute__ away for non-GCC
19376 compilers as well (i.e., the vendor C compiler).
19377 Suggested by Albert Chin-A-Young.
19379 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
19381 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
19382 canonical definition.
19383 * src/system.h: Use the canonical definition for PARAMS (avoids
19384 a conflict with the macro from lib/hash.h).
19386 2002-01-11 Akim Demaille <akim@epita.fr>
19388 * configure.in: Use AC_FUNC_STRNLEN.
19389 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
19391 2002-01-09 Akim Demaille <akim@epita.fr>
19393 * src/files.c, src/files.h (output_infix): New.
19394 (tab_extension): Remove.
19395 (compute_base_names): Compute the former, drop the latter.
19396 * src/output.c (prepare): Insert the muscles `output-infix', and
19398 * src/parse-skel.y (string, string.1): New.
19399 (section.header): Use it.
19400 (section.yacc): Remove.
19401 (prefix): Remove too.
19402 * src/scan-skel.l: Adjust.
19403 * src/bison.simple, src/bison.hairy: Adjust.
19405 2002-01-09 Akim Demaille <akim@epita.fr>
19407 * configure.in (WERROR_CFLAGS): Compute it.
19408 * src/Makefile.am (CFLAGS): Pass it.
19409 * tests/atlocal.in (CFLAGS): Idem.
19410 * src/files.c: Fix a few warnings.
19411 (get_extension_index): Remove, unused.
19413 2002-01-08 Akim Demaille <akim@epita.fr>
19415 * src/getargs.c (AS_FILE_NAME): New.
19416 (getargs): Use it to convert DOSish file names.
19417 * src/files.c (base_name): Rename as full_base_name to avoid
19418 clashes with `base_name ()'.
19419 (filename_split): New.
19420 (compute_base_names): N-th rewrite, using filename_split.
19422 2002-01-08 Akim Demaille <akim@epita.fr>
19424 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
19425 New, stolen from the Fileutils 4.1.
19426 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
19427 * configure.in: Check for the presence of memrchr, and of its
19430 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
19432 * lib/hash.h (__P): Added definition for this macro.
19433 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
19434 BUILT_SOURCES, to ensure they are generated first.
19435 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
19436 %error-verbose to allow bootstrapping with bison 1.30x.
19438 2002-01-06 Akim Demaille <akim@epita.fr>
19440 * src/reader.c (parse_braces): Don't fetch the next char, the
19441 convention is to fetch on entry.
19442 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
19443 'switch' without a following semicolon.
19444 * tests/regression.at (braces parsing): New.
19446 2002-01-06 Akim Demaille <akim@epita.fr>
19448 Bison is dead wrong in its RR conflict reports.
19450 * tests/torture.at (GNU Cim Grammar): New.
19451 * src/conflicts.c (count_rr_conflicts): Fix.
19453 2002-01-06 Akim Demaille <akim@epita.fr>
19455 Creating package.m4 from configure.ac causes too many problems.
19457 * tests/Makefile.am (package.m4): Create it by hand,
19458 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
19460 2002-01-06 Akim Demaille <akim@epita.fr>
19462 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
19465 2002-01-04 Paul Eggert <eggert@twinsun.com>
19467 * doc/bison.texinfo (Debugging):
19468 Remove YYSTDERR; it's no longer defined or used.
19469 Also, s/cstdio.h/cstdio/.
19471 2002-01-03 Akim Demaille <akim@epita.fr>
19473 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
19475 2002-01-03 Akim Demaille <akim@epita.fr>
19477 * src/parse-skel.y (process_skeleton): Don't bind the parser's
19478 tracing code to --trace, wait for a better --trace option, with
19481 2002-01-03 Akim Demaille <akim@epita.fr>
19483 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
19484 The ISO C++ standard is extremely clear about it: stderr is
19485 considered a macro, not a regular symbol (see table 94 `Header
19486 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
19487 Therefore std:: does not apply to it. It still does with fprintf.
19488 Also, s/cstdio.h/cstdio/.
19490 2002-01-03 Akim Demaille <akim@epita.fr>
19492 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
19493 for non system headers.
19495 2002-01-02 Akim Demaille <akim@epita.fr>
19497 Equip the skeleton chain with location tracking, runtime trace,
19498 pure parser and scanner.
19500 * src/parse-skel.y: Request a pure parser, locations, and prefix
19502 (%union): Having several members with the same type does not help
19503 type mismatches, simplify.
19504 (YYPRINT, yyprint): New.
19505 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
19506 (skel_error): this.
19508 * src/scan-skel.l: Adjust to these changes.
19509 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
19510 (LOCATION_PRINT, skel_control_t): New.
19512 2001-12-30 Akim Demaille <akim@epita.fr>
19514 * src/parse-skel.y: Get rid of the shift/reduce conflict:
19515 replace `gb' with BLANKS.
19516 * src/scan-skel.l: Adjust.
19518 2001-12-30 Akim Demaille <akim@epita.fr>
19520 * src/system.h: We don't need nor want bcopy.
19521 Throw away MS-DOS crap: we don't need getpid.
19522 * configure.in: We don't need strndup. It was even causing
19523 problems: because Flex includes the headers *before* us,
19524 _GNU_SOURCE is not defined by config.h, and therefore strndup was
19526 * lib/xstrndup.c: New.
19527 * src/scan-skel.l: Use it.
19528 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
19529 * src/parse-skel.y: Use %directives instead of #defines.
19531 2001-12-30 Akim Demaille <akim@epita.fr>
19533 * src/skeleton.h: New.
19534 * src/output.c (output_parser, output_master_parser): Remove, dead
19536 * src/output.h (get_lines_number, actions_output, guards_output)
19537 (token_definitions_output): Prototype them.
19538 * src/parse-skel.y: Add the license notice.
19539 Include output.h and skeleton.h.
19540 (process_skeleton): Returns void, and takes a single parameter.
19541 * src/scan-skel.l: Add the license notice.
19542 Include skeleton.h.
19543 Don't use %option yylineno: it seems that then Flex imagines
19544 REJECT has been used, and therefore it won't reallocate its
19545 buffers (which makes no other sense to me than a bug). It results
19546 in warnings for `unused: yy_flex_realloc'.
19548 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
19550 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
19551 (MUSCLE_INSERT_PREFIX): ...to there.
19552 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
19553 (MUSCLE_INSERT_PREFIX): Move from here...
19555 * src/bison.hairy: Add a section directive. Put braces around muscle
19556 names. This parser skeleton is still broken, but Bison should not
19557 choke on a bad muscle 'syntax'.
19558 * src/bison.simple: Add a section directive. Put braces around muscle
19561 * src/files.h (strsuffix, stringappend): Add declarations.
19562 (tab_extension): Add declaration.
19563 (short_base_name): Add declaration.
19565 * src/files.c (strsuffix, stringappend): No longer static. These
19566 functions are used in the skeleton parser.
19567 (tab_extension): New.
19568 (compute_base_names): Use the computations done in this function
19569 to guess if the generated parsers should have '.tab' in their
19571 (short_base_name): No longer static.
19573 * src/output.c (output_skeleton): New.
19574 (output): Disable call to output_master_parser, and give a try to
19575 a new skeleton handling system.
19576 (guards_output, actions_output): No longer static.
19577 (token_definitions_output, get_lines_number): No longer static.
19579 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
19581 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
19584 * src/parse-skel.y: New file.
19585 * src/scan-skel.l: New file.
19587 2001-12-29 Akim Demaille <akim@epita.fr>
19589 %name-prefix is broken.
19591 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
19592 Adjust all dependencies.
19593 * tests/headers.at (export YYLTYPE): Strengthen this test: use
19596 Renaming yylval but not yylloc is not consistent. Now we do.
19598 * src/bison.simple: Prefix yylloc if used.
19599 * doc/bison.texinfo (Decl Summary): Document that.
19601 2001-12-29 Akim Demaille <akim@epita.fr>
19603 * doc/bison.texinfo: Promote `%long-directive' over
19605 Remove all references to fixed-output-files, yacc is enough.
19607 2001-12-29 Akim Demaille <akim@epita.fr>
19609 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
19610 user prologue. These are defaults.
19611 * tests/actions.at (Mid-rule actions): Make sure the user can
19612 define YYDEBUG and YYERROR_VERBOSE.
19614 2001-12-29 Akim Demaille <akim@epita.fr>

19618 * tests/headers.at (export YYLTYPE): New, make sure it does.
19619 * tests/regression.at (%union and --defines, Invalid CPP headers):
19621 * tests/headers.at: here.
19623 2001-12-29 Akim Demaille <akim@epita.fr>
19625 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
19627 2001-12-29 Akim Demaille <akim@epita.fr>
19629 * tests/actions.at (Mid-rule actions): Output on a single line
19630 instead of several.
19632 2001-12-29 Akim Demaille <akim@epita.fr>
19634 * doc/bison.texinfo: Formatting changes.
19636 2001-12-29 Akim Demaille <akim@epita.fr>
19638 Don't store the token defs in a muscle, just be ready to output it
19639 on command. Now possible via `symbols'. Fixes a memory leak.
19641 * src/output.c (token_definitions_output): New.
19642 (output_parser, header_output): Use it.
19643 * src/reader.c (symbols_save): Remove.
19645 2001-12-29 Akim Demaille <akim@epita.fr>
19647 * src/bison.simple: Do not provide a default for YYSTYPE and
19648 YYLTYPE before the user's prologue. Otherwise it's hardly... a
19651 2001-12-29 Akim Demaille <akim@epita.fr>
19653 Mid-rule actions are simply... ignored!
19655 * src/reader.c (readgram): Be sure to attach mid-rule actions to
19656 the empty-rule associated to the dummy symbol, not to the host
19658 * tests/actions.at (Mid-rule actions): New.
19660 2001-12-29 Akim Demaille <akim@epita.fr>
19664 * src/reader.c (reader): Free grammar.
19666 2001-12-29 Akim Demaille <akim@epita.fr>
19670 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
19671 since it allocates it for each state, although only one is needed.
19672 (allocate_storage): Do it here.
19674 2001-12-29 Akim Demaille <akim@epita.fr>
19676 * src/options.h, src/options.c (create_long_option_table): Rename
19678 (long_option_table_new): this, with a clearer prototype.
19679 (percent_table): Remove, unused,
19680 * src/getargs.c (getargs): Adjust.
19682 2001-12-29 Akim Demaille <akim@epita.fr>
19684 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c

19688 2001-12-29 Akim Demaille <akim@epita.fr>
19690 * src/lalr.c (build_relations): Rename `states' as `states1'.
19691 Sorry, I don't understand exactly what it is, no better name...
19693 2001-12-29 Akim Demaille <akim@epita.fr>
19695 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
19696 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

19712 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
19713 Adjust all users to use symbols[i]->prec or ->assoc.

19718 Adjust all users to use symbols[i]->tag.
19720 2001-12-29 Akim Demaille <akim@epita.fr>

19724 * src/reader.c (packsymbols): Fill this table.
19726 * src/conflicts.c (resolve_sr_conflict): Adjust.
19727 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
19729 Use symbols[i]->tag instead of tags[i].
19731 2001-12-29 Akim Demaille <akim@epita.fr>
19733 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
19734 In addition, put a comment in there, to replace...
19735 * tests/regression.at (%union and C comments): Remove.
19737 2001-12-29 Akim Demaille <akim@epita.fr>
19739 * tests/regression.at (Web2c Actions): Blindly move the actual
19740 output as expected output. The contents *seem* right to me, but I
19741 can't pretend reading perfectly parser tables... Nonetheless, all
19742 the other tests pass correctly, the table look OK, even though the
19743 presence of `$axiom' is to be noted: AFAICS it is useless (but
19746 2001-12-29 Akim Demaille <akim@epita.fr>
19748 * src/reader.c (readgram): Don't add the rule 0 if there were no
19749 rules read. In other words, add it _after_ having performed
19750 grammar sanity checks.
19751 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
19753 2001-12-29 Akim Demaille <akim@epita.fr>
19755 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
19756 visible, and some states have now a different number.
19758 2001-12-29 Akim Demaille <akim@epita.fr>
19760 * src/reader.c (readgram): Bind the initial rule's lineno to that
19762 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
19763 (Solved SR Conflicts): Adjust rule 0's line number.
19765 2001-12-29 Akim Demaille <akim@epita.fr>
19767 Fix the `GAWK Grammar' failure.
19769 * src/LR0.c (final_state): Initialize to -1 so that we do compute
19770 the reductions of the first state which was mistakenly confused
19771 with the final state because precisely final_state was initialized
19773 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
19774 now noticed by Bison.
19775 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
19776 have a reduction on $default.
19778 2001-12-29 Akim Demaille <akim@epita.fr>
19780 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
19782 * src/closure.c (print_closure): Likewise.
19783 * src/derives.c (print_derives): Likewise.
19784 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
19787 2001-12-29 Akim Demaille <akim@epita.fr>
19789 * src/lalr.c (lookaheads_print): New.
19790 (lalr): Call it when --trace-flag.
19791 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
19794 2001-12-29 Akim Demaille <akim@epita.fr>
19796 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
19797 when walking through ritem, even via rule->rhs.
19798 * src/reduce.c (dump_grammar, useful_production, reduce_output)
19799 (useful_production, useless_nonterminals): Likewise.
19800 (reduce_grammar_tables): Likewise, plus update nritems.
19801 * src/nullable.c (set_nullable): Likewise.
19802 * src/lalr.c (build_relations): Likewise.
19803 * tests/sets.at (Nullable): Adjust.
19804 Fortunately, now, the $axiom is no longer nullable.
19806 2001-12-29 Akim Demaille <akim@epita.fr>
19808 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

19816 2001-12-29 Akim Demaille <akim@epita.fr>
19818 * src/output.c: Comment changes.
19820 2001-12-27 Paul Eggert <eggert@twinsun.com>
19822 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
19823 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
19824 Sparc, as they were causing more porting problems than the
19825 (minor) performance improvement was worth.
19827 Also, catch up with 1.31's YYSTD.
19829 2001-12-27 Akim Demaille <akim@epita.fr>
19831 * src/output.c (output_gram): Rely on nritems, not the
19832 0-sentinel. See below.
19833 Use -1 as separator, not 0.
19834 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
19835 Rely on -1 as separator in yyrhs, instead of 0.
19836 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
19837 twice `Now at end of input', therefore there are two lines less to
19840 2001-12-27 Akim Demaille <akim@epita.fr>
19842 * tests/regression.at (Unresolved SR Conflicts):
19843 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
19846 2001-12-27 Akim Demaille <akim@epita.fr>
19848 * src/LR0.c (new_state): Recognize the final state by the fact it
19849 is reached by eoftoken.
19850 (insert_start_shifting_state, insert_eof_shifting_state)
19851 (insert_accepting_state, augment_automaton): Remove, since now
19852 these states are automatically computed from the initial state.
19853 (generate_states): Adjust.
19854 * src/print.c: When reporting a rule number to the user, substract
19855 1, so that the axiom rule is rule 0, and the first user rule is 1.
19856 * src/reduce.c: Likewise.
19857 * src/print_graph.c (print_core): For the time being, just as for
19858 the report, depend upon --trace-flags to dump the full set of
19860 * src/reader.c (readgram): Once the grammar read, insert the rule
19861 0: `$axiom: START-SYMBOL $'.
19862 * tests/set.at: Adjust: rule 0 is now displayed, and since the
19863 number of the states has changed (the final state is no longer
19864 necessarily the last), catch up.
19866 2001-12-27 Akim Demaille <akim@epita.fr>
19868 Try to make the use of the eoftoken valid. Given that its value
19869 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
19870 is used instead of > 0 where appropriate, (ii), depend upon nritems
19871 instead of the 0-sentinel.
19873 * src/gram.h, src/gram.c (nritems): New.
19874 Expected to be duplication of nitems, but for the time being...
19875 * src/reader.c (packgram): Assert nritems and nitems are equal.
19876 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
19877 * src/closure.c (print_closure, print_fderives): Likewise.

19879 * src/print.c (print_core, print_grammar): Likewise.
19880 * src/print_graph.c: Likewise.
19882 2001-12-27 Akim Demaille <akim@epita.fr>
19884 * src/main.c (main): If there are complains after grammar
19885 reductions, then output the report anyway if requested, then die.
19886 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
19887 * src/reader.c (eoftoken): New.
19888 (parse_token_decl): If the token being defined has value `0', it
19890 (packsymbols): No longer hack `tags' to insert `$' by hand.
19891 Be sure to preserve the value of the eoftoken.
19892 (reader): Make sure eoftoken is defined.
19893 Initialize nsyms to 0: now eoftoken is created just like the others.
19894 * src/print.c (print_grammar): Don't special case the eof token.
19895 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
19896 lie anyway, albeit pleasant.
19897 * tests/calc.at: Exercise error messages with eoftoken.
19898 Change the grammar so that empty input is invalid.
19899 Adjust expectations.
19900 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
19902 2001-12-27 Akim Demaille <akim@epita.fr>
19904 * configure.in: Check the protos of strchr ans strspn.
19905 Replace strchr if needed.
19906 * src/system.h: Provide the protos of strchr, strspn and memchr if
19908 * lib/strchr.c: New.
19909 * src/reader.c (symbols_save): Use strchr.
19911 2001-12-27 Akim Demaille <akim@epita.fr>
19913 * src/print.c, src/print_graph.c (escape): New.
19914 Use it to quote the TAGS outputs.
19915 * src/print_graph.c (print_state): Now errors are in red, and
19916 reductions in green.
19917 Prefer high to wide: output the state number on a line of its own.
19919 2001-12-27 Akim Demaille <akim@epita.fr>
19921 * src/state.h, src/state.c (reductions_new): New.
19922 * src/LR0.c (set_state_table): Let all the states have a
19923 `reductions', even if reduced to 0.
19924 (save_reductions): Adjust.

19942 2001-12-27 Akim Demaille <akim@epita.fr>
19944 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
19945 * src/print.c: here.
19946 (lookaheadset, shiftset): New, used as additional storage by
19948 (print_results): Adjust.
19949 (print_shifts, print_gotos, print_errs): New, extracted from...
19950 (print_actions): here.
19951 * src/print_graph.c (print_actions): Remove dead code.
19953 2001-12-27 Akim Demaille <akim@epita.fr>
19955 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
19958 2001-12-27 Akim Demaille <akim@epita.fr>
19960 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
19961 (build_relations): Adjust.
19963 2001-12-27 Akim Demaille <akim@epita.fr>
19965 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
19968 2001-12-27 Akim Demaille <akim@epita.fr>
19970 * src/reader.c (packgram): Catch nitems overflows.
19972 2001-12-27 Akim Demaille <akim@epita.fr>
19974 * src/files.c, src/files.h (guard_obstack): Remove.
19975 * src/output.c (output): Adjust.
19976 * src/reader.c (parse_braces): New, factoring...
19977 (copy_action, copy_guard): these two which are renamed as...
19978 (parse_action, parse_guard): these.
19979 As a voluntary consequence, using braces around guards is now
19982 2001-12-27 Akim Demaille <akim@epita.fr>
19984 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
19985 * src/reader.c (symbol_list): `guard' and `guard_line' are new
19987 (symbol_list_new): Adjust.
19988 (copy_action): action_line is the first line, not the last.
19989 (copy_guard): Just as for actions, store the `action' only, not
19990 the switch/case/break flesh.
19991 Don't parse the user action that might follow the guard, let...
19992 (readgram): do it, i.e., now, there can be an action after a
19994 In other words the guard is just explicitly optional.
19995 (packgram): Adjust.
19996 * src/output.c (guards_output): New.
19997 (output_parser): Call it when needed.
19998 (output): Also free the guard and attrs obstacks.
19999 * src/files.c, src/files.h (obstack_save): Remove.
20000 (output_files): Remove.
20001 As a result, if one needs the former `.act' file, using an
20002 appropriate skeleton which requires actions and guards is now
20004 * src/main.c (main): Adjust.
20005 * tests/semantic.at: New.
20006 * tests/regression.at: Use `input.y' as input file name.
20007 Avoid 8+3 problems by requiring input.c when the test needs the

20012 * src/reader.c (symbol_list_new): Be sure to initialize all the
20015 2001-12-27 Akim Demaille <akim@epita.fr>
20017 All the hacks using a final pseudo state are now useless.
20019 * src/LR0.c (set_state_table): state_table holds exactly nstates.
20020 * src/lalr.c (nLA): New.
20021 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
20022 instead of lookaheadsp from the pseudo state (nstate + 1).
20024 2001-12-27 Akim Demaille <akim@epita.fr>
20026 * src/output.c (action_row, token_actions): Use a state_t instead
20027 of a integer, and nlookaheads instead of the following state's

20034 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
20035 (conflicts_print, print_reductions): Use a state_t instead of an
20036 integer when referring to a state.
20037 As much as possible, depend upon nlookaheads, instead of the
20038 `lookaheadsp' member of the following state (since lookaheads of
20039 successive states are successive, the difference between state n + 1
20040 and n served as the number of lookaheads for state n).
20041 * src/lalr.c (add_lookback_edge): Likewise.
20042 * src/print.c (print_core, print_actions, print_state)
20043 (print_results): Likewise.

20053 Add plenty of `static'.
20055 2001-12-27 Akim Demaille <akim@epita.fr>
20057 * src/output.c (prepare): Drop the muscle `ntbase' which
20058 duplicates ntokens.
20059 * src/bison.simple: Formatting/comment changes.
20060 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
20061 is an undocumented synonym.
20063 2001-12-22 Akim Demaille <akim@epita.fr>
20065 * src/output.c (output_table_data): Change the prototype to use
20066 `int' for array ranges: some invocations do pass an int, not a
20068 Reported by Wayne Green.
20070 2001-12-22 Akim Demaille <akim@epita.fr>
20072 Some actions of web2c.y are improperly triggered.
20073 Reported by Mike Castle.
20075 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

20088 2001-12-18 Akim Demaille <akim@epita.fr>
20090 Some host fail on `assert (!"foo")', which expands to
20091 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
20092 Reported by Nelson Beebee.
20094 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
20095 `#define it_succeeded 0' and `assert (it_succeeded)'.
20097 2001-12-17 Marc Autret <autret_m@epita.fr>
20099 * src/bison.simple: Don't hard code the skeleton line and filename.
20100 * src/output.c (output_parser): Rename 'line' as 'output_line'.
20101 New line counter 'skeleton_line' (skeleton-line muscle).
20103 2001-12-17 Paul Eggert <eggert@twinsun.com>
20105 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
20106 YYDEBUG must be defined to a nonzero value.
20108 * src/bison.simple (yytname): Do not assume that the user defines
20109 YYDEBUG to a properly parenthesized expression.
20111 2001-12-17 Akim Demaille <akim@epita.fr>
20113 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
20114 nlookaheads is a new member.
20116 * src/lalr.h (nlookaheads): Remove this orphan declaration.
20117 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
20120 2001-12-17 Akim Demaille <akim@epita.fr>
20122 * src/files.h, src/files.c (open_files, close_files): Remove.
20123 * src/main.c (main): Don't open/close files, nor invoke lex_free,
20125 * src/reader.c (reader): Do it.
20127 2001-12-17 Akim Demaille <akim@epita.fr>
20129 * src/conflicts.c (print_reductions): Formatting changes.
20131 2001-12-17 Akim Demaille <akim@epita.fr>
20133 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
20134 (flush_reduce): New.
20135 (resolve_sr_conflict): Adjust.
20137 2001-12-17 Akim Demaille <akim@epita.fr>
20139 * src/output.c (output_obstack): Be static and rename as...
20140 (format_obstack): this, to avoid any confusion with files.c's
20142 * src/reader.h (muscle_obstack): Move to...
20143 * src/output.h: here, since it's defined in output.c.
20145 2001-12-17 Akim Demaille <akim@epita.fr>
20147 * src/output.c (action_row, save_column, default_goto)
20148 (sort_actions, matching_state, pack_vector): Better variable
20151 2001-12-17 Akim Demaille <akim@epita.fr>
20153 * src/output.c: Various formatting changes.
20155 2001-12-17 Akim Demaille <akim@epita.fr>
20157 * src/files.c (output_files): Free the output_obstack.
20158 * src/main.c (main): Call print and print_graph conditionally.
20159 * src/print.c (print): Work unconditionally.
20160 * src/print_graph.c (print_graph): Work unconditionally.
20161 * src/conflicts.c (log_resolution): Output only if verbose_flag.
20163 2001-12-16 Marc Autret <autret_m@epita.fr>
20165 * src/output.c (actions_output): Fix. When we use %no-lines,
20166 there is one less line per action.
20168 2001-12-16 Marc Autret <autret_m@epita.fr>
20170 * src/bison.simple: Remove a useless #line directive.
20171 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
20172 * src/output.c (get_lines_number): New.
20173 (output_parser): Adjust, now takes care about the lines of a
20175 Fix line numbering.
20176 (actions_output): Computes the number of lines taken by actions.
20177 (output_master_parser): Insert new skeleton which is the name of
20178 the output parser file name.
20180 2001-12-15 Marc Autret <autret_m@epita.fr>
20182 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
20184 2001-12-15 Marc Autret <autret_m@epita.fr>
20186 * src/output.c (output_gram): Keep track of the hairy one.
20188 2001-12-15 Akim Demaille <akim@epita.fr>
20190 Make `make distcheck' work.
20192 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
20193 system.h which uses libgettext.h.
20195 2001-12-15 Akim Demaille <akim@epita.fr>
20197 * src/nullable.c (set_nullable): Useless rules must be skipped,
20198 otherwise, since we range over their symbols, we might look at a
20199 nonterminal which no longer ``exists'', i.e., it is not counted in
20200 `nvars', hence we overflow our arrays.
20202 2001-12-15 Akim Demaille <akim@epita.fr>
20204 The header can also be produced directly, without any obstack!
20207 * src/files.c, src/files.h (defines_obstack): Remove.
20208 (compute_header_macro): Global.
20209 (defines_obstack_save): Remove.
20210 * src/reader.c (parse_union_decl): No longer output to
20211 defines_obstack: its content can be found in the `stype' muscle
20213 (output_token_translations): Merge into...
20214 (symbols_output): this.
20216 (symbols_save): this.
20218 * src/output.c (header_output): New.
20221 2001-12-15 Akim Demaille <akim@epita.fr>
20223 * src/reader.c (parse_union_decl): Instead of handling two obstack
20224 simultaneously, use one to define the `stype' muscle, and use the
20225 value of the latter to fill defines_obstack.
20226 (copy_comment): Remove.
20227 (copy_comment2): Work for a single obstack.
20229 (copy_comment): this.
20231 2001-12-15 Akim Demaille <akim@epita.fr>
20233 * src/lex.c, src/lex.h (xgetc): No longer static.
20234 * src/reader.c (parse_union_decl): Revamp.
20236 2001-12-15 Akim Demaille <akim@epita.fr>
20238 Still making progress in separating Bison into (i) input, (ii)
20239 process, (iii) output: now we can directly output the parser file
20240 without using table_obstack at all.
20242 * src/files.c, src/files.h (table_obstack): Bye bye.
20243 (parser_file_name): New.
20244 * src/files.c (compute_output_file_names): Compute it.
20245 * src/output.c (actions_output, output_parser)
20246 (output_master_parser): To a file instead of an obstack.
20248 2001-12-15 Akim Demaille <akim@epita.fr>
20250 Attach actions to rules, instead of pre-outputting them to
20253 * src/gram.h (rule_t): action and action_line are new members.
20254 * src/reader.c (symbol_list): Likewise.
20255 (copy_action): Save the actions within the rule.
20256 (packgram): Save them in rule_table.
20257 * src/output.c (actions_output): New.
20258 (output_parser): Use it on `%%actions'.
20259 (output_rule_data): Don't free rule_table.
20261 (prepare): Don't save the `action' muscle.
20262 * src/bison.simple: s/%%action/%%actions/.
20264 2001-12-15 Akim Demaille <akim@epita.fr>
20266 * src/reader.c (copy_action): When --yacc, don't append a `;'
20267 to the user action: let it fail if lacking.
20268 Suggested by Arnold Robbins and Tom Tromey.
20270 2001-12-14 Akim Demaille <akim@epita.fr>
20272 * src/lex.c (literalchar): Simply return the char you decoded, non
20273 longer mess around with obstacks and int pointers.
20274 Adjust all callers.
20276 2001-12-14 Akim Demaille <akim@epita.fr>
20278 * src/lex.c (literalchar): Don't escape the special characters,
20279 just decode them, and keep them as char (before, eol was output as
20280 the 2 char string `\n' etc.).
20281 * src/output.c (output_rule_data): Use quotearg to output the
20284 2001-12-13 Paul Eggert <eggert@twinsun.com>
20286 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
20287 Do not infringe on the global user namespace when using C++.
20288 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
20289 All uses of `fprintf' and `stderr' changed.
20291 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
20293 2001-12-13 Akim Demaille <akim@epita.fr>
20295 The computation of nullable is broken: it doesn't handle empty
20298 * tests/torture.at (GNU AWK Grammar): New.
20299 * tests/sets.at (Nullable): New.
20300 * src/nullable.c (set_nullable): Instead of blindly looping over
20301 `ritems', loop over the rules, and then over their rhs's.
20303 Work around Autotest bugs.
20305 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
20306 frame, because Autotest understand lines starting with a `+' as
20307 traces from the shell. Then, they are not processed properly.
20308 Admittedly an Autotest bug, but we don't have time to wait for
20309 Autotest to catch up.
20310 * tests/regression.at (Broken Closure): Adjust to the new table
20313 * tests/sets.at: here.
20315 2001-12-13 Akim Demaille <akim@epita.fr>
20317 * src/closure.c (closure): Use nrules instead of playing tricks
20318 with BITS_PER_WORD.
20320 2001-12-13 Akim Demaille <akim@epita.fr>
20322 * src/print.c (print_actions): Output the handling of `$' as the
20323 traces do: shifting the token EOF. Before EOF was treated as a
20325 * tests/regression.at: Adjust some tests.
20326 * src/print_graph.c (print_core): Complete the set of items via
20327 closure. The next-to-final and final states are still unsatisfying,
20328 but that's to be addressed elsewhere.
20329 No longer output the rule numbers, but do output the state number.
20330 A single loop for the shifts + gotos is enough, but picked a
20331 distinct color for each.
20332 (print_graph): Initialize and finalize closure.
20334 2001-12-13 Akim Demaille <akim@epita.fr>
20336 * src/reader.c (readgram): Remove dead code, an strip useless
20338 (get_type): Remove, unused.
20340 2001-12-12 Akim Demaille <akim@epita.fr>
20342 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
20343 on that of lib/error.c.
20345 2001-12-12 Akim Demaille <akim@epita.fr>
20347 Some hosts don't like `/' in includes.
20349 * src/system.h: Include libgettext.h without qualifying the path.
20350 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
20353 2001-12-11 Marc Autret <autret_m@epita.fr>
20355 * src/output.c (output_parser): Remove useless muscle.
20357 2001-12-11 Marc Autret <autret_m@epita.fr>
20359 * src/bison.simple: Remove #line just before %%epilogue. It
20360 is now handled in ...
20361 * src/reader.c (read_additionnal_code): Add the output of a
20362 #line for the epilogue.
20364 2001-12-10 Marc Autret <autret_m@epita.fr>
20366 * src/reader.c (copy_definition): Re-use CPP-outed code which
20367 replace precedent remove.
20368 * src/bison.simple: Remove #line before %%prologue because
20369 %%input-line is wrong at this time.
20371 2001-12-10 Marc Autret <autret_m@epita.fr>
20373 * src/reader.c (symbols_output): Clean up.
20374 * src/output.c (output_gram, output): Clean up.
20376 2001-12-10 Akim Demaille <akim@epita.fr>
20378 * src/lalr.c (initialize_lookaheads): New. Extracted from...
20379 * src/LR0.c (set_state_table): here.
20380 * src/lalr.c (lalr): Call it.
20382 2001-12-10 Akim Demaille <akim@epita.fr>
20384 * src/state.h (shifts): Remove the `number' member: shifts are
20385 attached to state, hence no longer need to be labelled with a
20388 2001-12-10 Akim Demaille <akim@epita.fr>
20390 Now that states have a complete set of members, the linked list of
20391 shifts is useless: just fill directly the state's shifts member.
20393 * src/state.h (shifts): Remove the `next' member.
20394 * src/LR0.c (first_state, last_state): Remove.
20395 Adjust the callers.
20396 (augment_automaton): Don't look for the shifts that must be added
20397 a shift on EOF: it is those of the state we looked for! But now,
20398 since shifts are attached, it is no longer needed to looking
20399 merely by its id: its number.
20401 2001-12-10 Akim Demaille <akim@epita.fr>
20403 * src/LR0.c (augment_automaton): Better variable locality.
20404 Remove an impossible branch: if there is a state corresponding to
20405 the start symbol being shifted, then there is shift for the start
20406 symbol from the initial state.
20408 2001-12-10 Akim Demaille <akim@epita.fr>
20410 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
20411 only when appropriate: when insert_start_shifting_state' is not
20413 * tests/regression.at (Rule Line Numbers): Adjust.
20415 2001-12-10 Akim Demaille <akim@epita.fr>
20417 * src/LR0.c (augment_automaton): Now that all states have shifts,
20418 merge the two cases addition shifts to the initial state.
20420 2001-12-10 Akim Demaille <akim@epita.fr>
20422 * src/lalr.c (set_state_table): Move to...
20424 * src/lalr.c (lalr): Don't call it...
20425 * src/LR0.c (generate_states): do it.
20426 * src/LR0.h (first_state): Remove, only the table is used.
20428 2001-12-10 Akim Demaille <akim@epita.fr>
20430 * src/LR0.h (first_shift, first_reduction): Remove.
20431 * src/lalr.c: Don't use first_shift: find shifts through the
20434 2001-12-10 Akim Demaille <akim@epita.fr>
20436 * src/LR0.c: Attach shifts to states as soon as they are
20438 * src/lalr.c (set_state_table): Instead of assigning shifts to
20439 state, just assert that the mapping was properly done.
20441 2001-12-10 Akim Demaille <akim@epita.fr>
20443 * src/LR0.c (insert_start_shift): Rename as...
20444 (insert_start_shifting_state): this.
20445 (insert_eof_shifting_state, insert_accepting_state): New.
20446 (augment_automaton): Adjust.
20447 Better locality of the variables.
20448 When looking if the start_symbol is shifted from the initial
20449 state, using `while (... symbol != start_symbol ...)' sounds
20450 better than `while (... symbol < start_symbol ...)': If fail
20451 to see how the order between symbols could be relevant!
20453 2001-12-10 Akim Demaille <akim@epita.fr>
20455 * src/getargs.h: Don't declare `spec_name_prefix' and
20456 `spec_file_prefix', declared by src/files.h.
20457 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
20458 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
20459 * src/output.c (prepare): Adjust.
20460 * src/reader.c (symbols_output): Likewise.
20461 * src/vmsgetargs.c: Vaguely adjust, but who cares?
20463 2001-12-10 Akim Demaille <akim@epita.fr>
20465 * src/muscle_tab.c (muscle_init): NULL is a better default than
20468 2001-12-10 Akim Demaille <akim@epita.fr>
20470 * src/reader.c (reader): Calling symbols_output once is enough.
20472 2001-12-10 Akim Demaille <akim@epita.fr>
20474 Now that states have a complete set of members, the linked list of
20475 reductions is useless: just fill directly the state's reductions
20478 * src/state.h (struct reductions): Remove member `number' and
20480 * src/LR0.c (first_reduction, last_reduction): Remove.
20481 (save_reductions): Don't link the new reductions, store them in
20483 * src/lalr.c (set_state_table): No need to attach reductions to
20484 states, it's already done.
20485 * src/output.c (output_actions): No longer free the shifts, then
20486 the reductions, then the states: free all the states and their
20489 2001-12-10 Akim Demaille <akim@epita.fr>
20491 * src/options.c (OPTN, DRTV, BOTH): New.
20492 (option_table): Use them.
20494 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
20495 the job of system.h.
20496 * src/options.c: Don't include stdio.h and xalloc.h for the same
20499 2001-12-10 Akim Demaille <akim@epita.fr>
20501 * src/output.c (output, prepare): Make sure the values of the
20502 muscles `action' and `prologue' are 0-terminated.
20504 2001-12-10 Akim Demaille <akim@epita.fr>
20506 Clean up GCC warnings.
20508 * src/reader.c (copy_action): `buf' is not used.
20509 (parse_skel_decl): Be static.
20510 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
20511 * src/options.h (create_long_option_table): Have a real prototype.
20512 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
20513 (hash_delete_at): Return const void *.
20514 Adjust casts to preserve the const.
20516 2001-12-10 Akim Demaille <akim@epita.fr>
20518 * configure.in: Require 2.52g.
20519 M4 is not needed, but AUTOM4TE is.
20520 * m4/m4.m4: Remove.
20521 * tests/Makefile.am: Adjust.
20523 2001-12-10 Akim Demaille <akim@epita.fr>
20525 One structure for states is enough, even though theoretically
20526 there are LR(0) states and LALR(1) states.
20528 * src/lalr.h (state_t): Remove.
20529 (state_table): Be state_t **, not state_t *.
20530 * src/state.h (core, CORE_ALLOC): Rename as...
20531 (state_t, STATE_ALLOC): this.
20532 Add the LALR(1) members: shifts, reductions, errs.
20533 * src/LR0.c (state_table): Rename as...
20534 (state_hash): this, to avoid name clashes with the global
20536 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
20537 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
20539 2001-12-10 Akim Demaille <akim@epita.fr>
20541 Bison dumps core on bash.y.
20542 Reported by Pascal Bart.
20544 * src/warshall.c (bitmatrix_print): New.
20546 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
20547 j must be the outer loop.
20548 * tests/regression.at (Broken Closure): New.
20550 2001-12-05 Akim Demaille <akim@epita.fr>
20552 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
20554 Reported by Peter Hamorsky.
20556 2001-12-05 Akim Demaille <akim@epita.fr>
20558 * src/conflicts.c (err_table): Remove.
20559 (resolve_sr_conflict): Adjust.
20560 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
20562 (state_t.reductions, state_t.shifts): this.
20564 2001-12-05 Akim Demaille <akim@epita.fr>
20566 * src/reduce.c (reduce_grammar_tables): No longer disable the
20567 removal of useless rules via CPP but via `if (0)', so that the
20568 compiler still check the code is valid.
20569 For instance, it should have noticed `rline' no longer exists: use
20570 the `line' member of rule_t.
20571 * src/gram.c (dummy, rline): Remove, unused.
20573 2001-12-05 Akim Demaille <akim@epita.fr>
20575 * src/output.c (pack_vector): Use assert, not berror.
20576 * src/main.c (berror): Remove, unused.
20578 2001-12-05 Akim Demaille <akim@epita.fr>
20580 New experimental feature: if --verbose --trace output all the
20581 items of a state, not only its kernel.
20583 * src/print.c (print_core): If `trace_flag', then invoke closure
20584 before outputting the items of the state (print_core is no longer
20585 a correct name them).
20586 (print_results): Invoke new_closure/free_closure if needed.
20588 2001-12-05 Akim Demaille <akim@epita.fr>
20590 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
20591 * src/closure.c, src/closure.h (itemsetsize): Rename as...
20592 (nitemset): for consistency with the rest of the project.
20594 2001-12-05 Akim Demaille <akim@epita.fr>
20596 * src/closure.c (print_closure): Improve.
20597 (closure): Use it for printing input and output.
20599 2001-12-05 Akim Demaille <akim@epita.fr>
20601 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
20602 indexed by nonterminals.
20604 2001-12-05 Akim Demaille <akim@epita.fr>
20606 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
20608 * src/warshall.h: Remove accidental duplication of the content.
20610 2001-12-05 Akim Demaille <akim@epita.fr>
20612 * src/closure.c (set_fderives): De-obfuscate.

20620 * src/closure.c (set_firsts): De-obfuscate.
20622 2001-12-05 Akim Demaille <akim@epita.fr>
20624 * src/output.c (action_row): De-obfuscate
20625 using the good o' techniques: arrays not pointers, variable
20626 locality, BITISSET, RESETBIT etc.
20628 2001-12-05 Akim Demaille <akim@epita.fr>
20630 Pessimize the code to simplify it: from now on, all the states
20631 have a valid SHIFTS, which NSHIFTS is possibly 0.
20633 * src/LR0.c (shifts_new): Be global and move to..
20634 * src/state.c, src/state.h: here.
20635 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
20636 * src/print_graph: Adjust.

20640 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
20641 * src/conflicts.c: Use it.
20642 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
20643 incorrectly ``simplified''.
20645 2001-12-05 Akim Demaille <akim@epita.fr>
20647 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
20648 using the good o' techniques: arrays not pointers, variable
20649 locality, BITISSET, RESETBIT etc.
20651 2001-12-05 Akim Demaille <akim@epita.fr>
20653 * src/state.h (SHIFT_SYMBOL): New.

20683 2001-12-05 Akim Demaille <akim@epita.fr>
20685 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.

20696 (transpose): Use it.
20697 Use arrays instead of pointers.
20699 2001-12-05 Akim Demaille <akim@epita.fr>
20701 * src/lalr.c (maxrhs): Move to...
20702 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
20703 * src/lalr.c (build_relations): Adjust.
20705 2001-12-05 Akim Demaille <akim@epita.fr>
20707 * src/lalr.c (transpose): Free the memory allocated to the
20708 argument, as it is replaced by the results by the unique caller.
20709 (build_relations): Merely invoke transpose: it handles the memory
20711 Improve variable locality.
20712 Avoid variables used as mere abbreviations.
20713 (compute_lookaheads): Use arrays instead of pointers.
20715 2001-12-05 Akim Demaille <akim@epita.fr>
20717 * src/lalr.c (initialize_F): Improve variable locality.
20718 Avoid variables used as mere abbreviations.

20731 2001-12-05 Akim Demaille <akim@epita.fr>
20733 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
20734 the handling of squeue.
20735 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
20737 2001-12-05 Akim Demaille <akim@epita.fr>
20739 Because useless nonterminals are now kept alive (instead of being
20740 `destroyed'), we now sometimes examine them, and store information
20741 related to them. Hence we need to know their number, and adjust
20742 memory allocations.
20744 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
20746 * src/LR0.c (allocate_itemsets): The memory allocated to
20747 `symbol_count' was used for two different purpose: once to count
20748 the number of occurrences of each symbol, and later reassigned to
20749 `shift_symbol', containing the symbol that can be shifted from a
20751 Deobfuscate, i.e., allocate, use and free `symbol_count' here
20753 (new_itemsets): Allocate `shift_symbol' here.
20754 (allocate_itemsets): symbol_count includes useless nonterminals.
20755 Make room for them.
20756 (free_storage): Use `free', not `XFREE', for pointers that cannot
20759 2001-12-05 Akim Demaille <akim@epita.fr>

20765 2001-12-05 Akim Demaille <akim@epita.fr>
20767 * src/gram.c, src/gram.h (ritem_print): New.
20768 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
20769 (This useless function was defined only to work around VMS linkers
20770 that can't handle compilation units with variables only).
20771 * src/reduce.c (dump_grammar): Use it to trace the construction of
20774 2001-12-04 Paul Eggert <eggert@twinsun.com>
20776 * src/bison.simple (union yyalloc): Change member names
20777 to be the same as the stack names.
20778 (yyparse): yyptr is now union yyalloc *, not char *.
20779 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
20780 and may generate better code on some machines.
20781 (yystpcpy): Use prototype if __STDC__ is defined, not just
20782 if __cplusplus is defined.
20784 2001-11-30 Akim Demaille <akim@epita.fr>
20786 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
20787 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
20788 Gettext doesn't compile cleanly, and dies with -Werror.
20789 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
20790 Include WARNING_CFLAGS here.
20791 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
20792 before being defined.

20796 * lib/quotearg.h (quotearg_n, quotearg_n_style):
20797 First arg is int, not unsigned.
20798 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
20799 (SIZE_MAX, UINT_MAX): New macros.
20800 (quotearg_n_options): Abort if N is negative.
20801 Avoid overflow check on hosts where size_t is 64 bits and int
20802 is 32 bits, as overflow is impossible there.
20803 Fix off-by-one typo that caused unnecessary reallocation.
20805 2001-11-29 Paul Eggert <eggert@twinsun.com>
20807 Name space cleanup in generated parser.
20809 * doc/bison.texinfo (Bison Parser): Discuss system headers
20810 and their effect on the user name space.
20812 * src/bison.simple:
20813 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
20814 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
20815 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
20817 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
20818 on user names when possible.
20820 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
20821 Simplify test for whather <alloca.h> exists.
20823 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
20825 (<stdio.h>): Include if YYDEBUG.
20827 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
20828 ! defined (yyoverflow) && ! defined (yymemcpy).
20830 (yymemcpy, yyparse): Rename local variables as needed so that
20831 they all begin with 'yy'.
20833 (yystrlen, yystpcpy): New functions.
20835 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
20838 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
20839 instead of relying on string.h functions. Use YYSTACK_ALLOC
20840 and YYSTACK_FREE instead of malloc and free.
20842 2001-11-30 Akim Demaille <akim@epita.fr>
20844 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
20845 before their first uses.

20855 if body instead of `;' to pacify GCC's warnings.
20857 2001-11-30 Akim Demaille <akim@epita.fr>
20859 Instead of mapping the LHS of unused rules to -1, keep the LHS
20860 valid, but flag the rules as invalid.
20862 * src/gram.h (rule_t): `useful' is a new member.
20863 * src/print.c (print_grammar): Adjust.
20864 * src/derives.c (set_derives): Likewise.
20865 * src/reader.c (packgram, reduce_output): Likewise.
20866 * src/reduce.c (reduce_grammar_tables): Likewise.
20867 * tests/reduce.at (Underivable Rules, Useless Rules): New.

20876 2001-11-30 Akim Demaille <akim@epita.fr>
20878 * src/reduce.c (nonterminals_reduce): Instead of throwing away
20879 useless nonterminals, move them at the end of the symbol arrays.
20880 (reduce_output): Adjust.
20881 * tests/reduce.at (Useless Nonterminals): Adjust.
20883 2001-11-30 Akim Demaille <akim@epita.fr>

20893 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
20894 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
20896 (union yyalloc): New type.
20897 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
20898 an arbitrary restriction on hosts where size_t is wider than int.
20900 (yyparse): Don't dump core if alloca or malloc fails; instead, report
20901 a parser stack overflow. Allocate just one block of memory for all
20902 three stacks, instead of allocating three blocks; this typically is
20903 faster and reduces fragmentation.
20905 Do not limit the number of items in the stack to a value that fits
20906 in 'int', as this is an arbitrary limit on hosts with 64-bit
20907 size_t and 32-bit int.
20909 2001-11-29 Marc Autret <autret_m@epita.fr>
20911 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
20912 of defining YYERROR_VERBOSE.
20913 [AT_DATA]: $4 is now out of C declarations in the prologue.
20915 2001-11-28 Marc Autret <autret_m@epita.fr>
20917 * src/reader.c (parse_dquoted_param): New.
20918 (parse_skel_decl): Use it.

20927 * src/getargs.h: Clean its extern declaration.

20959 * src/closure.c (closure): `b' and `ruleno' denote the same value:
20962 2001-11-28 Akim Demaille <akim@epita.fr>
20964 * src/closure.c (closure): Instead of looping over word in array
20965 then bits in words, loop over bits in array.
20967 2001-11-28 Akim Demaille <akim@epita.fr>
20969 * src/closure.c (closure): No longer optimize the special case
20970 where all the bits of `ruleset[r]' are set to 0, to make the code

20980 * src/reduce.c (reduce_print): Use ngettext.

20983 2001-11-28 Akim Demaille <akim@epita.fr>
20985 * src/reduce.c (dump_grammar): Don't translate trace messages.
20987 2001-11-28 Akim Demaille <akim@epita.fr>
20989 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
20990 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,

20994 2001-11-27 Paul Eggert <eggert@twinsun.com>
20996 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
20997 use alloca when we didn't want to, and vice versa.

21080 * src/conflicts.c (conflicts_print): Don't complain at all when
21081 there are no reduce/reduce conflicts, and as many shift/reduce
21082 conflicts as expected.
21083 * tests/regression.at (%expect right): Adjust.
21085 2001-11-23 Akim Demaille <akim@epita.fr>

21106 2001-11-23 Akim Demaille <akim@epita.fr>
21108 Attaching lineno to buckets is stupid, since only one copy of each

21112 * src/reader.c (rline_allocated): Remove, unused.

22712 * src/conflicts.c (conflict_report): Be sure not to append to res
22713 between two calls, which could happen if both first sprintf were
22714 skipped, but not the first cp += strlen.
22716 2001-02-08 Akim Demaille <akim@epita.fr>
22718 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
22719 New, from fileutils 4.0.37.
22720 * configure.in: Require Autoconf 2.49c. I took some time before
22721 making this decision. This is the only way out for portability
22722 issues in Bison, it would mean way too much duplicate effort to
22723 import in Bison features implemented in 2.49c since 2.13.
22724 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
22726 2001-02-02 Akim Demaille <akim@epita.fr>

22741 2001-01-19 Akim Demaille <akim@epita.fr>
22743 * src/lex.h: Rename all the tokens:
22744 s/\bENDFILE\b/tok_eof/g;
22745 s/\bIDENTIFIER\b/tok_identifier/g;
22747 Let them be enums, not #define, to ease debugging.

22755 2001-01-18 Akim Demaille <akim@epita.fr>
22757 Since we now use obstacks, more % directives can be enabled.

22760 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

22763 instead of returning a token.

22765 * src/reader.c (read_declarations): Adjust.
22766 * src/files.c (open_files): Don't call `compute_base_names', don't

22770 * src/output.c (output_headers): Document the fact that this patch
22771 introduces a guaranteed SEGV for semantic parsers.
22772 * doc/bison.texinfo: Document them.
22773 * tests/suite.at: Exercise these %options.
22775 2000-12-20 Akim Demaille <akim@epita.fr>

22785 (obstack_fgrow4): New.
22787 2000-12-20 Akim Demaille <akim@epita.fr>
22789 * src/files.c (open_files): Fix the computation of short_base_name
22790 in the case of `-o foo.tab.c'.

22840 (obstack_grow_string): this.
22841 * src/output.c (output_parser): Recognize `%% actions' instead of
22843 * src/bison.s1: s/$/%% actions/.
22844 * src/bison.hairy: Likewise.
22846 2000-12-19 Akim Demaille <akim@epita.fr>
22848 * src/output.c (output_parser): Compute the `#line' lines when
22850 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.

22873 2000-12-19 Akim Demaille <akim@epita.fr>
22875 * src/files.c (open_files): Yipee! We no longer need all the code

22907 * lib/obstack.h: Formatting changes.
22908 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
22909 prevents type checking.
22910 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
22911 cast the value to (void *): assigning a `foo *' to a `void *'

22933 Use them to declare the variables which are global or local to
22936 2000-11-17 Akim Demaille <akim@epita.fr>
22938 * acconfig.h: Remove, no longer used.
22940 2000-11-07 Akim Demaille <akim@epita.fr>
22942 * src: s/Copyright (C)/Copyright/g.
22944 2000-11-07 Akim Demaille <akim@epita.fr>
22946 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
22948 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
22950 2000-11-07 Akim Demaille <akim@epita.fr>
22952 * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

22964 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
22965 `const' their input argument (`data' or `address').
22966 Adjust the corresponding macros to include `const' in casts.
22968 2000-11-03 Akim Demaille <akim@epita.fr>
22970 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
22971 s/PFILE1/BISON_HAIRY/.
22972 Adjust dependencies.
22974 2000-11-03 Akim Demaille <akim@epita.fr>
22976 For some reason, this was not applied.
22978 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
22979 `unlink': it's no longer used.
22981 2000-11-03 Akim Demaille <akim@epita.fr>
22983 * src/files.c (skeleton_find): New function, eved out of...

22988 Don't use `atexit'.
22990 * src/files.c (obstack_save): New function.
22991 (done): Rename as...
22992 (output_files): this.
22993 Use `obstack_save'.
22994 * src/main.c (main): Don't use `atexit' to register `done', since
22995 it no longer has to remove tmp files, just call `output_files'
22996 when there are no errors.
22998 2000-11-02 Akim Demaille <akim@epita.fr>
23000 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
23001 `unlink': it's no longer used.
23002 * src/files.h: Formatting changes.
23004 2000-11-02 Akim Demaille <akim@epita.fr>
23006 Remove the last uses of mktemp and unlink/delete.
23008 * src/files.c (fdefines, ftable): Removed.
23009 (defines_ostack, table_obstack): New.
23010 Adjust dependencies of the former into uses of the latter.
23011 * src/output.c (output_short_or_char_table, output_short_table):

23068 * src/reader.c (copy_comment2): Expect the input stream to be on
23069 the `/' which is suspected to open a comment, instead of being
23070 called after `//' or `/*' was read.
23071 (copy_comment, copy_definition, parse_union_decl, copy_action)
23072 (copy_guard): Adjust.
23074 2000-10-16 Akim Demaille <akim@epita.fr>
23076 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
23077 `read_signed_integer'.
23079 2000-10-16 Akim Demaille <akim@epita.fr>
23081 * src/reader.c (copy_dollar): New function.
23082 (copy_guard, copy_action): Use it.
23084 2000-10-16 Akim Demaille <akim@epita.fr>
23086 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
23087 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
23088 New files, from Fileutils 4.0.27.
23089 * src/main.c (printable_version): Remove.
23090 * src/lex.c, src/reader.c: Use `quote'.
23092 2000-10-04 Akim Demaille <akim@epita.fr>
23094 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
23096 2000-10-04 Akim Demaille <akim@epita.fr>
23098 * doc/bison.texinfo: Various typos spotted by Neil Booth.
23100 2000-10-04 Akim Demaille <akim@epita.fr>
23102 When a literal string is used to define two different tokens,
23103 `bison -v' segfaults.
23104 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
23106 * tests/regression.m4: New file.
23107 Include the core of the sample provided by Piotr Gackiewicz.
23108 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
23111 2000-10-04 Akim Demaille <akim@epita.fr>
23113 * src/reader.c (parse_expect_decl): Keep `count' within the size
23117 2000-10-02 Paul Eggert <eggert@twinsun.com>
23119 * bison.s1 (yyparse): Assign the default value
23120 unconditionally, to avoid a GCC warning and make the parser a
23123 2000-10-02 Akim Demaille <akim@epita.fr>
23125 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
23128 2000-10-02 Akim Demaille <akim@epita.fr>
23130 * src/derives.c, src/print.c, src/reduce.c: To ease the
23131 translation, move some `\n' out of the translated strings.
23133 2000-10-02 Akim Demaille <akim@epita.fr>
23135 The location tracking mechanism is precious for parse error
23136 messages. Nevertheless, it is enabled only when `@n' is used in
23137 the grammar, which is a different issue (you can use it in error
23138 message, but not in the grammar per se). Therefore, there should
23139 be another means to enable it.
23141 * src/getargs.c (getargs): Support `--locations'.
23142 (usage): Report it.
23143 * src/getargs.h (locationsflag): Export it.
23144 * src/lex.c (percent_table): Support `%locations'.
23145 * src/reader.c (yylsp_needed): Remove this variable, now replaced
23146 with `locationsflag'.
23147 * doc/bison.texinfo: Document `--locations' and `%locations'.
23149 * tests/calc.m4: Test it.
23151 For regularity of the names, replace each
23152 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
23153 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
23154 In addition replace each `flag' with `_flag'.
23156 2000-10-02 Akim Demaille <akim@epita.fr>
23158 Also test parse error messages, including with YYERROR_VERBOSE.
23160 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
23162 Use it to check the computations.
23163 Use it to check `nonassoc' is honored.
23164 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
23165 `--yyerror-verbose'.
23166 (_AT_CHECK_CALC): Adjust to this option.
23167 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
23169 2000-10-02 Akim Demaille <akim@epita.fr>
23171 Test also `--verbose', `--defines' and `--name-prefix'. Testing
23172 the latter demonstrates a flaw in the handling of non debugging
23173 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
23174 was used in order to simplify:
23190 unfortunately this leads to a CPP conflict when
23191 `--name-prefix=foo' is used since it produces `#define yydebug
23194 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
23195 (YYDPRINTF): New macro.
23197 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
23199 Also test `--verbose', `--defines' and `--name-prefix'.
23201 2000-10-02 Akim Demaille <akim@epita.fr>
23203 Improve the readability of the produced parsers.
23205 * src/bison.s1: Formatting changes.
23206 Improve the comment related to the `$' mark.
23207 (yydefault): Don't fall through to `yyresume': `goto' there.
23208 * src/output.c (output_parser): When the `$' is met, skip the end
23210 New variable, `number_of_dollar_signs', to check there's exactly
23211 one `$' in the parser skeleton.
23213 2000-10-02 Akim Demaille <akim@epita.fr>
23215 * lib/xstrdup.c: New file, from the fileutils.
23216 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
23217 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
23218 instead of strlen + xmalloc + strcpy.
23219 * src/symtab.c (copys): Remove, use xstrdup instead.
23221 2000-10-02 Akim Demaille <akim@epita.fr>
23223 * src/gram.h (associativity): New enum type which replaces the

23242 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
23243 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
23244 difficult and introduced a lot of core dump. It turns out that
23245 Bison used an implementation of `xmalloc' based on `calloc', and
23246 at various places it does depend upon the initialization to 0. I
23247 have not tried to isolate the pertinent places, and all the former
23248 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
23249 someone should address this issue.
23251 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
23252 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

23348 output_short_table.
23350 2000-10-02 Akim Demaille <akim@epita.fr>
23352 `user_toknums' is output as a `short[]' in `output.c', while it is
23353 defined as a `int[]' in `reader.c'. For consistency with the
23354 other output tables, `user_toknums' is now defined as a table of

23398 * src/system.h: Define PARAMS.

23619 Change the handling of @s so that they behave exactly like $s.
23620 There is now a pseudo variable @$ (readble and writable), location
23621 of the lhs of the rule (by default ranging from the location of
23622 the first symbol of the rhs, to the location of the last symbol,
23623 or, if the rhs is empty, YYLLOC).

23630 same way you stack YYVAL.

23632 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

23658 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

24385 (parse_percent_token): Added % declarations as another
24386 way to specify the flags -n, -l, and -r. Also added hooks for
24387 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
24388 major changes to files.c.
24389 (lex) Retain in the incoming stream a character following
