55 Fix some comments concerning LR(0) versus LALR(1).
57 Stop equating LR(0) with nondeterminism and LALR(1) with
58 determinism. That is, if all states are consistent, then LR(0)
59 tables are deterministic. On the other hand, LALR(1) tables
60 might be nondeterministic before conflict resolution, and GLR
61 permits LALR(1) tables to remain nondeterministic.

140 portability: `<' and `>' are not always defined on addresses.
141 Specifically, don't sort objects by their memory addresses when
142 they're not allocated in the same array or other object. Though
143 I haven't found a test case where that fails on my platform, C
144 says the behavior is undefined.
145 * src/AnnotationList.c (AnnotationList__insertInto): Remove
146 FIXME. Use new id field of InadequacyList nodes rather than
147 their memory addresses when sorting.
148 (AnnotationList__compute_from_inadequacies): Add
149 inadequacy_list_node_count argument to pass to
150 InadequacyList__new_conflict.

163 2009-12-20 Joel E. Denny <jdenny@clemson.edu>
165 Fix handling of yychar manipulation in user semantic actions.
166 The problem was that yacc.c didn't always update the yychar
167 translation afterwards. However, other skeletons appear to be
168 fine. glr.c appears to already translate yychar before every
169 use. lalr1.cc does not define yychar and does not document its
170 replacement, yyla, for users. It does provide yyclearin, but
171 that does not manipulate yyla and thus requires no translation
172 update. In lalr1.java, yychar is out of scope during semantic
174 * NEWS (2.5): Document.
175 * data/yacc.c (YYBACKUP): Don't bother translating yychar into
177 (yyparse, yypush_parse): Instead, translate before every use of
178 yytoken, and add comments explaining this approach.
179 * tests/actions.at (Destroying lookahead assigned by semantic
180 action): New test group checking that translation happens before
181 lookahead destructor calls at parser return. Previously,
182 incorrect destructors were called.
183 * tests/conflicts.at (%error-verbose and consistent
184 errors): New test group checking that translation happens at
185 syntax error detection before the associated verbose error
186 message and the associated lookahead destructor calls. While
187 the destructor call is fixed by this patch, the verbose error
188 message is currently incorrect due to another bug (see
189 comments in test group), so this is an expected failure for now.

368 yysyntax_error: avoid duplicate lookahead collection.
369 Except when memory reallocation is required, this change
370 eliminates the need to invoke yysyntax_error twice and thus to
371 repeat the collection of lookaheads. It also prepares for
372 future extensions that will make those repetitions more
373 expensive and that will require additional memory management in
374 yysyntax_error. Finally, it fixes an obscure bug already
375 exercised in the test suite.
376 * data/yacc.c (yysyntax_error): Add arguments for message
377 buffer variables stored in the parser. Instead of size, return
378 status similar to yyparse status but indicating success of
379 message creation. Other than the actual reallocation of the
380 message buffer, import and clean up memory management code

577 Avoid compiler warning.
579 2009-08-27 Joel E. Denny <jdenny@clemson.edu>
581 tests: use perl for printing special sequences to files.
582 And skip tests if perl is not available. This is better than
583 playing tricks with shell portability. Suggested by Akim
585 * tests/input.at (Bad character literals): Use it here for
586 omitting final newlines.
587 (Bad escapes in literals): Use it here for special characters.
589 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
591 tests: show a use of %define lr.default-reductions "consistent"
592 * tests/conflicts.at (%nonassoc and eof): Extend to test that it
593 prevents the omission of expected tokens for %error-verbose.
595 2009-08-26 Akim Demaille <demaille@gostai.com>
597 tests: portability fix.
598 * tests/input.at (Bad escapes in literals): Don't expect "echo
599 '\0'" to output \ then 0.
601 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
603 Actually handle the yytable zero value correctly this time.
604 * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Don't
605 mention zero values in the YYTABLE comments.
606 * data/glr.c (yytable_value_is_error): Don't check for zero
608 * data/lalr1.cc (yy_table_value_is_error_): Likewise.
609 * data/yacc.c (yytable_value_is_error): Likewise.
610 * data/lalr1.java (yy_table_value_is_error_): Likewise.
611 (yysyntax_error): Fix typo in code: use yytable_ not yycheck_.
612 * src/tables.h: In header comments, explain why it's useless to
613 check for a zero value in yytable.
615 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
617 More fixes related to last two patches.
618 * data/c.m4 (b4_table_value_equals): Comment that YYID must be
620 * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Fix
621 yytable comments: zero indicates syntax error not default
623 * data/glr.c (yyis_pact_ninf): Rename to...
624 (yypact_value_is_default): ... this.
625 (yyisDefaultedState): Update for rename.
626 (yyis_table_ninf): Rename to...
627 (yytable_value_is_error): ... this, and check for value zero
628 besides just YYTABLE_NINF.
629 (yygetLRActions): Check for default value from yypact. It
630 appears that this check is always performed before this function
631 is invoked, and so adding the check here is probably redundant.
632 However, the code may evolve after this subtlety is forgotten.
633 Also, update for rename to yytable_value_is_error. Because that
634 macro now checks for zero, a different but equivalent branch of
635 the if-then-else here is evaluated.
636 (yyreportSyntaxError): Update for rename to
637 yytable_value_is_error. The zero condition was mishandled
639 (yyrecoverSyntaxError): Update for renames. No behavioral
641 * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_):
643 (yy_table_value_is_error_): New function.
644 (parse): Use new functions where possible. No behavioral
646 (yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_.
647 The zero condition was mishandled before.
648 * data/yacc.c (yyis_pact_ninf): Rename to...
649 (yypact_value_is_default): ... this.
650 (yyis_table_ninf): Rename to...
651 (yytable_value_is_error): ... this, and check for value zero
652 besides just YYTABLE_NINF.
653 (yysyntax_error): Update for rename to yytable_value_is_error.
654 The zero condition was mishandled before.
655 (yyparse): Update for renames. No behavioral changes.
656 * src/tables.h: Improve comments about yypact, yytable, etc.
657 more. Most importantly, say yytable value of zero means syntax
658 error not default action.

693 quote rather than implementing quoting here.
695 2009-08-20 Eric Blake <ebb9@byu.net>
697 Make previous patch more robust.
698 * src/output.c (ARRAY_CARDINALITY): New macro, copied from
700 (output_skeleton): Use it.
701 Suggested by Akim Demaille.
703 Import latest m4/m4.m4.
704 * submodules/autoconf: Update to autoconf 2.64.

711 Fix complaints about escape sequences.
712 Discussed starting at
713 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>.
714 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
715 For a \0 and similar escape sequences meaning the null
716 character, report an invalid escape sequence instead of an
717 invalid null character because the latter does not actually
718 appear in the user's input.
719 In all escape sequence complaints, don't escape the initial
720 backslash, and don't quote when the sequence appears at the end
721 of the complaint line unless there's whitespace that quotearg
723 Consistently say "invalid" not "unrecognized".
724 Consistently prefer "empty character literal" over "extra
725 characters in character literal" warning for invalid escape
726 sequences; that is, consistently discard those sequences.

762 build: lower gettext requirements.
764 Bison was uselessly requiring the formatstring macros from
765 gettext, which resulted in mo files not being installed on systems
766 that perfectly supported Bison mo files. Lower the requirement.

770 need-formatstring-macros.
771 Reported by Martin Jabocs.

817 defaults and checking into...
818 (prepare_percent_define_front_end_variables): ... this new
821 * src/scan-gram.l (INITIAL): For consistency with string
822 literals, don't store open quote on character literal. It's
823 discarded before returning anyway.
824 (SC_ESCAPED_CHARACTER): Similarly, don't store close quote.
825 Make length test more readable, and make the character stored
826 for an empty literal more obvious while consistent with the
829 * src/symtab.c, src/symtab.h: Rename USER_NUMBER_ALIAS to
830 USER_NUMBER_HAS_STRING_ALIAS throughout.
831 * src/symtab.c (symbol_make_alias): Remove comment from symtab.c
832 that is repeated in symtab.h. Improve argument names to make it
833 clear which side of the symbol-string alias pair is which.

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

963 (AT_TEST_TABLES_AND_PARSE): ... this now that the special
964 arguments are not needed because of the following changes.
966 Bison developers should use GNU M4 and should not use
967 POSIXLY_CORRECT when building the test suite, so do not

1164 remove useless variable.
1165 * src/getargs.c (skeleton_arg): Remove now useless variable.

1225 * src/files.c (tr): Move to...
1226 * src/getargs.c, src/getargs.h (tr): ... here because I can't

1410 * src/reader.c (reader): Default lr.type to "LALR".

2267 * NEWS (2.3b+): Rename to...
2268 (?.?): ... this because we're dropping the "+" version naming scheme,
2269 but, in general, we still can't be sure of our next release name.
2270 * bootstrap: Add a quick hack to remove from .gitignore the
2271 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
2272 entry. This should really be fixed in gnulib instead.
2273 * bootstrap.conf (gnulib_modules): Add gnumakefile.
2274 * configure.ac (AC_INIT): Set version name by invoking
2275 build-aux/git-version-gen.

2305 Fix some .gitignore and .cvsignore problems.
2306 * bootstrap (insert_sorted_if_absent): Replace all uses with...
2307 (insert_vc_ignore): ... this new function, which prepends `/' to all
2308 .gitignore entries before passing them to insert_sorted_if_absent.
2309 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
2310 .cvsignore files are maintained even though Bison developers run
2311 bootstrap while using Git.
2312 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
2315 * .gitignore (/*.patch *.log log patches applied): Remove, broken and

2331 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
2332 the first argument because it may become position-dependent, and unset
2333 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
2334 Add comments explaining these issues in more detail.
2336 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

2398 Revert prior patch, by working around autoconf regression.
2399 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
2400 ("Output file name: ("): Uncomment test.
2401 ("Output file name: )"): Likewise.
2402 Based on an idea from Noah Misch.
2404 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>

2407 2.61. Reported by Juan Manuel Guerrero at
2408 <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.

2420 Update to the current gnulib CVS repository, and fix trigraph handling
2422 * bootstrap: Update gnulib CVS repository URL.
2423 (symlink_to_dir): Encapsulate the code that guarantees the destination
2424 directory exists into...
2425 (check_dst_dir): ... this new function, and...
2426 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
2427 fail when copying files into lib/uniwidth/.
2428 * src/output.c (prepare_symbols): When writing yytname muscles, where
2429 symbol names will be encoded in C-string literals, tell quotearg to
2430 escape trigraphs. This used to be the default in gnulib.
2431 * tests/regression.at (Token definitions): Because of the change in
2432 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
2433 escapes trigraphs in symbol names. Thus, yytname no longer has
2434 trigraphs unnecessarily doubly escaped. Update test case output.
2435 Extend test case to be sure Bison's own error messages will no longer
2436 have trigraphs in symbol names unnecessarily escaped once.
2438 2008-04-20 Joel E. Denny <jdenny@ces.clemson.edu>

2451 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
2452 consistency. Update the -g and -x entries now that they take
2453 arguments. Use brackets to indicate optional arguments.
2454 * src/getargs.c (usage): Explain the relationship between arguments of
2455 long and short options more completely. Document --defines and -d
2456 separately since the former takes an argument but, for POSIX Yacc, the
2458 (short_options): Let -W take an optional argument like --warnings.

2473 -g and -x take optional arguments, just like their long options.

2476 Fix the handling of $opt which resulted in all the argument to be
2477 considered as optional.
2479 2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>

2515 * data/yacc.c: Clean up whitespace in the output a little.
2516 (yypstate_allocated): Define for impure push parsers regardless of
2517 whether the pull interface is also requested.
2518 * tests/push.at (Push Parsing: Multiple impure instances): Extend to
2519 check impure push parsers without the pull interface.
2521 * data/yacc.c (yypstate_new): Don't try to invoke yyerror since

3114 explains it more completely in the case of C++.
3115 (C++ Bison Interface): Mention `%define namespace' instead of
3117 (Table of Symbols): Remove the `%define push_pull' entry. The %define
3119 * tests/c++.at (Relative namespace references): New test case.

3164 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately

3213 parsing requests here...
3214 * data/yacc.c: ... hack this to switch to push.c any time
3215 b4_use_push_pull_flag or the %define variable push_pull is set. This
3216 will go away when we mv push.c yacc.c.
3217 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
3218 push parsing is not supported since unused %define variables are
3220 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.

3440 * src/getargs.h (no_parser_flag): Remove extern.
3441 * tests/regression.at (Web2c Actions): Remove comment that mentions
3444 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
3446 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
3447 name user variables starting with `yy'. Just pass NULL instead of a
3448 dummy local &yylval to yypush_parse.
3449 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
3452 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
3454 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
3455 true since it's then always used regardless of whether yyoverflow is
3456 defined. Reported by Christian Burger at
3457 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
3458 * THANKS: Add Christian Burger.
3460 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3461 node names: say "Decl Summary" not "Bison Declaration Summary".
3463 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
3465 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
3466 determine whether this function has already complained about an invalid
3467 value for a %define boolean variable, don't check whether Bison has
3468 ever examined the value. As written, the check was a tautology.
3469 Instead, record and check for this complaint using a separate muscle.
3471 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
3473 Fix push parsing memory leak reported by Brandon Lucia at
3474 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
3475 * THANKS: Add Brandon Lucia.
3476 * data/push.c (yypstate_delete): Free the stack if it was reallocated
3477 but the parse never completed and thus freed it.
3478 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
3479 * tests/testsuite.at: Include push.at.
3480 * test/push.at: New.
3481 (Push Parsing: Memory Leak for Early Deletion): New test case.
3483 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
3485 Improve handling of multiple S/R conflicts in the same state and of S/R
3486 conflicts involving multiple reductions.
3487 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
3488 set for a state here or Bison will abort if it is reassigned on a
3489 later conflicted reduction in the same state.
3490 Similarly, don't finalize and assign the solved conflicts report here
3491 or it will be lost if it is reassigned on a later conflicted reduction
3493 (set_conflicts): Instead, assign them both here after all S/R conflicts
3494 in the state have been fully examined.
3495 * src/print.c (shift_set): Rename to...
3496 (no_reduce_set): ... this.
3497 (print_reductions): Update for rename, and add %nonassoc error action
3498 tokens to no_reduce_set so that, when printing the first remaining
3499 reduction on an error action token, the reduction is enclosed in
3501 (print_results): Update for rename.
3502 * tests/conflicts.at (Solved conflicts report for multiple reductions
3503 in a state): New test case.
3504 (%nonassoc error actions for multiple reductions in a state): New test
3507 * src/main.c (main): Don't depend on C99 features.
3509 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
3511 * build-aux/.cvsignore: Add compile.
3512 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
3515 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
3517 * bootstrap (slurp): Create target directories that don't exist.
3518 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
3520 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
3522 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
3524 * closure.c (closure): Likewise.
3525 * state.h (reductions): Comment sorting of rules.
3526 (state): Comment sorting of items.
3528 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
3530 Fix C++ test cases after recent Gnulib changes. Discussed starting at
3531 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
3532 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
3533 definition in order to avoid Gnulib headers since we don't use config.h
3535 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
3536 rather than AT_DATA so that config.h is included.
3538 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
3540 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
3541 instead of fprintf. Guard these functions with #if YYDEBUG instead of
3542 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
3543 and so that YYFPRINTF is guaranteed to be defined here.
3545 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
3547 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
3549 (muscle_percent_define_check_values): ... this more helpful function.
3550 Again, it's not used yet, but it will be.
3551 * src/muscle_tab.h: Likewise.
3553 Improve some comments in parser table construction.
3554 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
3555 (generate_states): Don't mention ruleset, which is internal to closure.
3556 * src/closure.c (closure): Explain sorting of core and itemset, which
3557 is required for this function to behave correctly.
3558 * src/closure.h (closure): Mention sorting.
3560 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
3562 * src/lalr.c (state_lookahead_tokens_count): For code readability,
3563 move the check for disabled transitions to an aver since conflict
3564 resolution hasn't happened yet.
3566 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3567 labels a state as inconsistent just because it has error transitions.
3568 The original form of this check appeared in revision 1.1 of lalr.c,
3569 which was committed on 1991-12-21. Now (at least), changing the
3570 consistency label on such a state appears to have no useful effect in
3571 any of the places it is examined, which I enumerate below. The key
3572 point to understanding each item in this enumeration is that a state
3573 with an error transition is labelled consistent in the first place only
3574 if it has no rules, so the check cannot matter for states that have
3575 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3576 to try to identify its conflicts, and a state must have *rules* to have
3577 conflicts. (2) Labelling a state as inconsistent will affect how
3578 action_row sets the default *rule* for the state. (3) Labelling a
3579 state as inconsistent will cause build_relations to add lookback edges
3580 to *rules* in that state.
3581 * src/state.h (struct state): Word the comment for member consistent
3584 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
3586 Don't depend on C99 features.
3587 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
3588 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
3589 * src/reader.c (check_and_convert_grammar): Fix for-loop.
3590 * src/state.c (state_mark_reachable_states): Fix for-loop.
3591 (state_remove_unreachable_states): Fix for-loop.
3593 Don't widen struct state with member reachable just to temporarily
3594 record reachability. Instead, use a local bitset.
3595 * src/state.h (struct state): Remove member.
3596 * src/state.c (state_new): Don't initialize it.
3597 (state_mark_reachable_states): Rename to...
3598 (state_record_reachable_states): ... this, and use bitset.
3599 (state_remove_unreachable_states): Use bitset.
3601 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
3603 * src/Makefile.am (yacc): Quote target action commands properly so
3604 that the yacc script isn't corrupt. Reported by Hans Aberg at
3605 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
3607 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
3608 the case of pure parsers. Reported by Frans Englich at
3609 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
3610 * THANKS: Add Frans Englich.
3612 * NEWS (2.3a+): In the %code entry, reference section `Bison
3613 Declaration Summary' from the manual now since the %code summary has
3615 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
3616 in the rules section must be terminated by semicolons.
3618 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
3620 Extend the front-end API for %define variables to more completely
3621 mirror the back-end. This will be useful in the future.
3622 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
3623 Update comments to mention the new front-end counterparts of these
3625 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code

3635 * src/muscle_tab.h (muscle_percent_define_get,
3636 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
3639 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
3641 * NEWS (2.3a+): Mention yesterday's state-removal change.
3642 (2.3a): Remove the %language entry, which was added after 2.3a.
3643 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
3644 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
3645 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
3646 tests/existing.at: Update copyright date.
3648 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
3650 If conflict resolution makes states unreachable, remove those states,
3651 report rules that are then unused, and don't report conflicts in those

3674 (new_itemsets, save_reductions): Update for rename to nitemset.
3675 * src/closure.c (nritemset): Rename to...

3677 used in the comments.
3678 (closure): Update for rename.
3679 * src/closure.h (nritemset): Update extern to...
3680 (nitemset): ... this.

3799 * tests/input.at (%define errors): Update expected output.
3800 * tests/skeletons.at (%define boolean variables: invalid skeleton

3805 * src/print.c (lookahead_set, state_default_rule): Remove.
3806 (print_reductions): Replace state_default_rule invocation with
3807 equivalent use of yydefact, which was computed in token_actions in
3809 (print_results): Don't allocate lookahead_set.
3811 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
3813 * data/lalr1.java: Prefix all private members with yy.
3815 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
3817 Use YYFPRINTF instead of fprintf where appropriate. Reported by
3818 Sebastien Fricker at

3835 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
3837 Undo my 2007-02-07 change, switching back to the c-strcase module
3838 introduced in the 2007-02-03 change. Bruno Haible reported that
3839 the 2007-02-07 change would be dangerous in Turkish if we add a
3840 language whose name contains "i", since "i" is not lowercase "I"
3842 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
3843 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,

3863 * src/reader.c (packgram): Move translation of rule actions from the
3864 beginning of packgram to...
3865 (check_and_convert_grammar): ... here right before packgram is invoked
3866 so it's easier to write more complete comments, and remove redundant
3869 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
3871 As in semantic actions, make @$ in %initial-action, %destructor, and
3872 %printer imply %locations.
3873 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
3875 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
3876 (@$ in %initial-action implies %locations,
3877 @$ in %destructor implies %locations,
3878 @$ in %printer implies %locations): ... these new test cases.
3880 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
3882 Undo most of the 2007-02-03 change, switching to the strcase module
3883 now that gnulib strcase has been fixed.
3884 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
3885 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
3886 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
3887 * m4/.cvsignore: Add strcase.m4.
3888 * src/getargs.c: Revert 2007-02-03 change, as follows.
3889 Don't include c-strcase.h.
3890 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
3891 strcasecmp has "unspecified behavior" outside the POSIX locale,
3892 but it works fine in practice if at least one argument is ASCII,
3893 as is the case in Bison.
3895 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
3897 * tests/java.at: Skip tests if only one of javac/java is present.
3898 Reported by Joel E. Denny.
3899 * tests/atlocal.in: Adjust copyright years.
3901 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
3903 * data/lalr1.java (Stack): Work around old verifiers that disallow
3904 access to the private fields of an inner class, from the outer class.
3905 We can make Stack's fields public because user code doesn't have access
3906 to the instance of Stack used by parse(). Reported by Paul Eggert.
3908 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3910 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
3911 the right spot for these files?
3912 * bootstrap.conf (gnulib_modules): Add c-strcase.
3913 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
3915 * src/getargs.c: Include c-strcase.h.
3916 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
3917 to avoid unspecified behavior.
3919 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
3921 * doc/bison.texinfo (Decl Summary): Correct typo.
3923 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
3925 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
3926 Complain if the value does not match empty, "true" or "false".
3927 * data/c++.m4: Adjust default definitions of %define variables.
3928 * data/java.m4: Adjust default definitions of %define variables.
3929 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
3931 * tests/input.at (Boolean %define variables): Test new behavior.
3933 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
3935 * NEWS: Mention java.
3936 * TODO: Remove things that are done.
3937 * bootstrap.conf: Add javacomp-script and javaexec-script.
3938 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
3940 * data/Makefile.am: Add new files.
3941 * data/java-skel.m4: New.
3942 * data/java.m4: New.
3943 * data/lalr1.java: New.
3945 * doc/bison.texinfo: Put "A Complete C++ Example" under
3946 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
3947 under Other Languages.
3949 * src/getargs.c (valid_languages): Add Java.
3950 * src/getargs.h (struct bison_language): Update size of string fields.
3952 * tests/Makefile.am: Add java.at.
3953 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
3954 * tests/java.at: New.
3955 * tests/testsuite.at: Include it.
3957 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
3960 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
3961 at_directive_argv arguments so these no longer have to be global
3962 variables. Also, update the implementation for the following changes.
3963 (fail_for_at_directive_too_many_args,
3964 fail_for_at_directive_too_few_args): Add at_directive_name argument.
3965 (at_directive_name): Remove as at_directive_argv[0] will be used for
3967 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
3968 for the directive name.
3969 (at_directive_argc, at_directive_argv): Make these local within
3970 skel_lex instead of global.
3971 (INITIAL): Update directive start action for above changes.
3972 (SC_AT_DIRECTIVE_ARG): Rename to...
3973 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
3974 (SC_AT_DIRECTIVE_SKIP_WS): Update.
3975 (scan_skel): Move yylex_destroy to...
3976 (skel_scanner_free): ... here.
3977 * tests/skeletons.at (installed skeleton file name): Rename to...
3978 (installed skeleton file names): ... this.
3980 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
3982 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3983 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
3984 Summary" not "Directives".
3985 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
3986 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
3987 since the former is now the more complete one.
3988 (Prologue Alternatives): Likewise and do the same for %defines.
3989 (Table of Symbols): Add summary of %code, add summary of %define, and
3990 move full %code documentation to...
3991 (Decl Summary): ... here for consistency with other entries in these
3993 Move %define entry in order to keep this list alphabetized.
3994 Reword %define entry a little to put less emphasis on the skeleton
3995 concept, which most users shouldn't have to think about.
3997 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
3999 Adjust to recent gnulib changes.
4000 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
4001 Add string.h, string_.h, unistd_.h, wchar_.h.
4002 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
4003 * src/system.h: Don't include <stpcpy.h>; this is now done by
4006 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
4008 Simplify implementation of unqualified %code, implement macros for
4009 uniform treatment of boolean %define flags. Document %define.
4010 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
4011 b4_percent_code_ifdef): New.
4012 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
4013 * data/c++.m4: Define default value for global_tokens_and_yystype.
4014 * data/glr.cc: Likewise.
4015 * data/location.cc: Use b4_percent_define_flag_if.
4017 * doc/bison.texinfo (Decl Summary): Document %define.
4019 * src/parse-gram.y (Unqualified %code): Change muscle name to
4021 (content.opt): Default to empty.
4023 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
4025 Implement support for relative and absolute skeleton file names.
4026 Discussed starting at
4027 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
4028 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
4029 (Bison Options): Document in --skeleton entry.
4030 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
4031 full_skeleton can't necessarily hold all of pkgdatadir.
4032 If the specified skeleton file name contains a `/', don't prepend
4034 * src/parse-gram.y (prologue_declaration): If the specified skeleton
4035 file name contains a `/', prepend the grammar file directory.
4036 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
4037 * skeletons.at: New file.
4038 (relative skeleton file names): New test case.
4039 (installed skeleton file names): New test case.
4040 * tests/testsuite.at: Include skeletons.at.
4042 * bootstrap: Update copyright to 2007.
4044 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
4046 * bootstrap: Remove occurrences of .#bootmp from the files.
4048 2007-01-17 Akim Demaille <akim@epita.fr>
4050 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
4052 Use per-type %printer.
4054 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>

4064 2007-01-16 Akim Demaille <akim@epita.fr>
4066 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
4068 (Calc++ Scanner): Exit with failure if we can't open the input
4070 Accept "-" standing for stdin.
4071 (Calc++ Top Level): Print the result only if the parsing was
4074 2007-01-16 Akim Demaille <akim@epita.fr>
4076 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
4078 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
4079 and Joel E. Denny <jdenny@ces.clemson.edu>
4081 Clean up %define and %code implementation in M4 some. Most
4082 importantly, rename all related macros to be in the b4_percent_define
4083 and b4_percent_code namespaces. Also, complete support for `.' in
4084 %define variable names and %code qualifiers.
4085 * data/bison.m4 (b4_check_user_names): Check for special
4086 "SKELETON-NAMESPACE(name)" macros instead of using two nested
4088 (b4_get_percent_define, b4_get_percent_code): Rename to...
4089 (b4_percent_define_get, b4_percent_code_get): ... these.
4090 Extend documentation with examples.
4091 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
4092 b4_percent_define_skeleton_variables and
4093 b4_percent_code_skeleton_qualifiers.
4094 Expect any value for the %define variable `foo' to be stored in the
4095 macro named `b4_percent_define(foo)'; expect any %code blocks for the
4096 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
4097 expect any unqualified %code blocks to be stored in a macro named
4098 `b4_percent_code_unqualified'.
4099 Use m4_indir so that %define variable names and %code qualifiers can
4100 contain `.', which is allowed by the grammar parser.
4101 (b4_percent_define_default): New macro to set a default value for a
4103 (m4_wrap): Update wrapped code, and fix some underquoting.
4104 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
4105 Expect grammar uses of %define variables and %code qualifiers to be
4106 defined in b4_percent_define_user_variables and
4107 b4_percent_code_user_qualifiers.
4108 * data/c++.m4: Use b4_percent_define_default rather than
4109 m4_define_default. Fix some underquoting. Skeleton usage of %define
4110 variable define_location_comparison now implies skeleton usage of
4111 %define variable filename_type.
4112 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4113 data/push.c, data/yacc.c: Update macro names.
4114 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
4117 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
4119 DJGPP specific issues.
4121 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
4122 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
4124 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4126 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
4127 run parsers in all tests so that Valgrind is invoked during
4128 maintainer-check-valgrind.
4129 (Duplicate representation of merged trees): Free all semantic values.
4130 (Duplicated user destructor for lookahead): Likewise.
4132 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4134 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
4135 command-line prefix.
4136 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
4137 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
4138 miss Valgrind messages.
4139 (Exploding the Stack Size with Malloc): Likewise.
4141 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4143 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
4144 locals. Reported by Juan Manuel Guerrero at
4145 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
4146 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
4147 Fix some indentation also.
4148 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
4149 explaining this issue.
4151 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
4152 and Joel E. Denny <jdenny@ces.clemson.edu>
4154 Simplify union and prologue handling, and escape union and lex/parse
4155 params with digraphs.
4156 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
4157 values to the empty string since these are no longer guaranteed
4158 initialized by the front-end.
4159 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
4160 braces around b4_user_stype since this is no longer done by the
4162 * src/files.c, src/files.h (pre_prologue_obstack,
4163 post_prologue_obstack): Remove.
4164 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
4165 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
4166 with digraphs. This fixes lex params and parse params.
4167 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
4168 * src/output.c (prepare): Remove muscle insertion of the prologues.
4169 (output): Remove freeing of pre_prologue_obstack and
4170 post_prologue_obstack.
4171 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
4172 than prologue_augment for prologue parsing so you don't need prologue
4174 (grammar_declaration): For %union RHS, use `braceless' instead of
4175 "{...}" so that braces are already stripped and code is escaped with
4177 * src/reader.c (prologue_augment): Remove.
4178 (reader): Remove initialization of pre_prologue_obstack and
4179 post_prologue_obstack.
4180 * src/reader.h (prologue_augment): Remove.
4182 * data/c.m4: Remove stray parenthesis.
4184 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4186 Remove quotes from variables names in %define directives and from
4187 qualifiers in %code directives, and restrict the characters that are
4188 allowed in them to M4-friendly ones. For %define, continue to support
4189 the quoted form as a deprecated feature. Discussed starting at
4190 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
4191 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
4193 * doc/bison.texinfo (Prologue Alternatives): Update.
4194 (Decl Summary): In %defines entry, update mention of `%code requires'
4195 and `%code provides'.
4196 (C++ Location Values): Update %define uses.
4197 (Calc++ Parser Interface): Likewise.
4198 (Calc++ Parser): Likewise, and update `%code requires' uses.
4199 (Table of Symbols): Update %code documentation.
4200 * src/parse-gram.y (prologue_declaration): For %define variables, use
4201 `variable' instead of `STRING'.
4202 (grammar_declaration): For %code qualifiers, use `ID' instead of
4204 (variable): New nonterminal that takes an `ID' or a `STRING'.
4205 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
4207 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
4208 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
4209 (%define errors): Update %define uses.
4211 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4213 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
4214 instead of muscle_insert for %define values so that M4-special
4215 characters are replaced with digraphs.
4216 * tests/input.at (%define errors): Extend to check weird values.
4218 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4220 Instead of having skeletons declare all valid %define variables and
4221 %code qualifiers, provide macros that retrieve the associated values
4222 and build these lists automatically. Thus Bison will now warn when a
4223 variable or qualifier is not used by the skeleton in the current
4224 invocation regardless of whether it might sometimes be used by that
4225 skeleton in other invocations. Also, move all %define value macros to
4226 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
4227 form, which is replaced by %code.
4228 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
4229 (b4_check_user_names): ... this, and change the series of valid name
4230 arguments to a single list argument for names used in the skeleton
4231 similar to the existing list argument for names used in the grammar.
4232 Warn instead of complaining.
4233 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
4234 values and %code code, to format %code code properly, and to build
4235 lists of all %define variables and %code qualifiers used in the
4236 skeleton: b4_skeleton_percent_define_variables and
4237 b4_skeleton_percent_code_qualifiers.
4238 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
4240 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
4241 the skeleton names lists can finish building first. In place of
4242 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
4243 expect the lists b4_user_percent_define_variables and
4244 b4_user_percent_code_qualifiers.
4245 * data/c++.m4: Where setting default values for b4_parser_class_name,
4246 b4_location_type, b4_filename_type, b4_namespace, and
4247 b4_define_location_comparison, update their names to the
4248 b4_percent_define_ namespace.
4249 * data/glr.c: Don't use b4_check_percent_define_variables and
4250 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4251 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
4252 (b4_parser_class_name, b4_namespace): Define these using
4253 b4_get_percent_define for parser_class_name and namespace.
4254 * data/location.cc: Use b4_get_percent_define.
4255 * data/push.c: Don't use b4_check_percent_define_variables and
4256 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4257 * data/yacc.c: Likewise, and don't call m4_exit in
4258 b4_use_push_for_pull_if or m4_wrap code will never execute.
4259 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
4261 (muscle_grow_user_name_list): ... this for consistency with the
4262 terminology used in bison.m4.
4263 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
4264 %define variable names, and rename muscle used_percent_define_variables
4265 to user_percent_define_variables.
4266 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
4267 user_percent_code_qualifiers.
4269 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
4270 {CODE} form is no longer accepted.
4271 * tests/input.at (Reject bad %code qualifiers): Rename to...
4272 (Reject unused %code qualifiers): ... this, and update test output.
4273 (%define error): Update test output.
4275 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
4277 Check for unrecognized %define variables similar to checking for
4278 unrecognized %code qualifiers. Check for redefined %define variables.
4279 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
4281 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
4282 (b4_check_percent_define_variables): New, also wraps it.
4283 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
4284 variables using b4_check_percent_define_variables.
4285 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
4286 all those exercised in the test suite and all those listed in the
4287 `Default values' section of c++.m4. Are there others?
4288 * data/push.c, data/yacc.c: Declare no valid %define variables.
4289 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
4290 similar to muscle_find, but it works even when the muscle stores a
4292 (muscle_grow_used_name_list): New function for constructing the used
4293 name list muscles that b4_check_for_unrecognized_names requires.
4294 * src/parse-gram.y (prologue_declaration): Warn if a variable is
4295 %define'd more than once. Define the b4_used_percent_define_variables
4296 muscle with muscle_grow_used_name_list.
4297 (grammar_declaration): Abbreviate %code code with
4298 muscle_grow_used_name_list.
4299 * tests/input.at (%define errors): New.
4301 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4303 Provide warn_at, complain_at, and fatal_at function callbacks to the
4304 skeletons, and use this for %code qualifier complaints.
4305 * data/bison.m4 (b4_error_at): New, invoked by...
4306 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
4307 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
4308 @fatal_at(...@) directives.
4309 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
4310 qualifiers in b4_used_percent_code_qualifiers and to use
4312 * src/location.c, src/location.h (boundary_set_from_string): New global
4314 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
4316 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
4317 to b4_used_percent_code_qualifiers.
4318 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
4320 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
4321 (lineno): Rename to...
4322 (out_lineno): ... this so I don't misunderstand it again.
4323 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
4324 here; these newlines are in the input but not the output file.
4325 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
4326 (at_directive_perform): ... this new static function, and add handling
4327 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
4329 * tests/input.at (Reject bad %code qualifiers): Update test output with
4330 locations and extend.
4332 * tests/output.at (Output file name: [, Output file name: ]): Remove
4333 bogus comment about these tests failing.
4335 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4337 Clean up b4_check_percent_code_qualifiers a little.
4338 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
4339 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
4340 documentation and add examples.
4341 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
4344 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
4346 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
4347 unreliable -- especially when they're hidden inside another macro.
4348 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
4349 data/c.m4: Remove m4_divert(-1).
4350 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4351 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
4352 m4_divert_push(0) and m4_divert_pop(0).
4353 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
4354 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
4355 pushed and popped by m4sugar, should be first on the stack.
4357 Provide warn, complain, and fatal function callbacks to the skeletons.
4358 This provides more flexibility than m4_fatal, improves the error
4359 message format, and captures messages for translation. Discussed
4361 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
4362 * data/bison.m4 (b4_error): New, invoked by...
4363 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
4364 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
4365 directives. Because these M4 macros might be called when the current
4366 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
4367 the previous removal of uses of m4_divert, which caused trouble.
4368 (b4_check_percent_code_qualifiers): Use b4_complain instead of
4369 m4_fatal to report unrecognized %code qualifiers.
4370 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
4371 push parser requests.
4372 * data/glr.c: Use b4_complain instead of m4_fatal to report
4373 non-deterministic push parser requests.
4374 Update @output usage to @output(...@) form.
4375 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
4376 report missing %defines. Update @output usage to @output(...@) form.
4377 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
4379 * src/main.c (main): Invoke skel_scanner_free.
4380 * src/scan-skel.h (skel_scanner_free): Prototype new function.
4381 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
4382 obstack_for_string from flex-scanner.h.
4383 (YY_DECL): Use to declare skel_lex static.
4384 (decode_at_digraphs): Remove; now handled in the new
4385 SC_AT_DIRECTIVE_ARG start condition.
4386 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
4388 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
4389 at_directive_argv): New static globals.
4390 (INITIAL): Use fail_for_invalid_at.
4391 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
4392 recognize the start of a generalized `@directive(...@)' form and
4394 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
4395 directive args (using the new obstack_for_string), to decode the
4396 contained @ diagraphs, and to perform the directive. It recognizes
4397 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
4399 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
4400 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
4402 (scan_skel): Initialize obstack_for_string on the first call.
4403 (skel_scanner_free): New function to free obstack_for_string.
4404 * tests/input.at (Reject bad %code qualifiers): Update test output.
4406 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
4408 Consolidate the 4 prologue alternative directives (%code, %requires,
4409 %provides, and %code-top) into a single %code directive with an
4410 optional qualifier field. Discussed at
4411 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
4412 * NEWS (2.3a+): Rewrite the existing entry for the prologue
4414 * doc/bison.texinfo (Prologue Alternatives): Update.
4415 (Decl Summary): Update to %code "requires" and %code "provides".
4416 (Calc++ Parser): Update to %code "requires".
4417 (Table of Symbols): Remove entries for %requires, %provides, and
4418 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
4419 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
4420 are replaced by b4_percent_code_provides and b4_percent_code_requires,
4421 which are skeleton-specific.
4422 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
4423 declare what %code qualifiers it supports and to complain if any other
4424 qualifiers were used in the grammar.
4425 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
4426 and b4_user_code([b4_percent_code_provides]) in place of
4427 b4_user_requires and b4_user_provides.
4428 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
4429 Add b4_user_code([b4_percent_code_top]) and
4430 b4_user_code([b4_percent_code]).
4431 Invoke b4_check_percent_code_qualifiers.
4432 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4433 PERCENT_REQUIRES): Remove.
4434 (grammar_declaration): Remove RHS's for %code-top, %provides, and
4435 %requires. Rewrite the %code RHS as the unqualified form defining the
4436 muscle b4_percent_code. Add another RHS for the qualified %code form,
4437 which defines muscles of the form b4_percent_code_QUALIFIER and the
4438 b4_used_percent_code_qualifiers muscle.
4439 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4440 PERCENT_REQUIRES): Remove.
4441 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
4442 %code "requires" and %code "provides".
4443 * tests/input.at (Reject bad %code qualifiers): New.
4445 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4447 Use the new code_props interface for destructors and printers.
4448 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
4449 printer_location members, and change the type of the destructor and
4450 printer members to code_props.
4451 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
4452 symbol_printer_get, semantic_type_destructor_set,
4453 semantic_type_printer_set, default_tagged_destructor_set,
4454 default_tagless_destructor_set, default_tagged_printer_set,
4455 default_tagless_printer_set): Use code_props in arguments and return
4456 types in place of char const * and location.
4457 (symbol_destructor_location_get, symbol_printer_location_get): Remove
4458 since the locations are now contained in the return of
4459 symbol_destructor_get and symbol_printer_get.
4460 * src/output.c (symbol_destructors_output, symbol_printers_output):
4462 (symbol_code_props_output): ... this to eliminate duplicate code.
4463 (output_skeleton): Update to use symbol_code_props_output.
4464 * src/reader.c (symbol_should_be_used): Update use of
4465 symbol_destructor_get.
4466 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4467 Update uses of the various _destructor_set and _printer_set functions.
4468 * src/symtab.c: (default_tagged_destructor_location,
4469 default_tagless_destructor_location, default_tagged_printer_location,
4470 default_tagless_printer_location): Remove since we...
4471 (default_tagged_destructor, default_tagless_destructor,
4472 default_tagged_printer, default_tagless_printer): ... change the type
4473 of these to code_props.
4474 (symbol_new, semantic_type_new, symbol_destructor_set,
4475 semantic_type_destructor_set, symbol_destructor_get,
4476 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
4477 symbol_check_alias_consistency, default_tagged_destructor_set,
4478 default_tagless_destructor_set, default_tagged_printer_set,
4479 default_tagless_printer_set): Update.
4480 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
4481 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
4483 (symbol_print): Use SYMBOL_CODE_PRINT.
4485 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4487 Use the new code_props interface for rule actions.
4488 * src/symlist.h (symbol_list): Replace action, action_location, and
4489 used members with a code_props action_props member.
4490 * src/reader.c (symbol_should_be_used, grammar_rule_check,
4491 grammar_midrule_action, grammar_current_rule_merge_set,
4492 grammar_current_rule_symbol_append, packgram): Update.
4493 * src/scan-code.h (translate_rule_action): Remove, no longer used.
4494 * src/scan-code.l (handle_action_dollar): Update.
4495 (translate_rule_action): Remove, no longer used.
4496 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
4498 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4500 Use the new code_props interface in parse-gram.y.
4501 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
4502 Update all uses of translate_* functions to use the new code_props
4503 interface and to use gram_scanner_last_string_free and
4504 code_scanner_last_string_free where possible.
4505 (grammar_declaration): symbol_list_destructor_set and
4506 symbol_list_printer_set now perform the translation, so don't do it
4507 here. Use gram_scanner_last_string_free where possible.
4508 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
4509 translate_code): Remove, no longer used.
4510 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
4511 symbol_list_printer_set): Perform code translation here rather than
4512 depending on the caller to do so.
4514 * src/symlist.h (struct symbol_list): Correct some documentation typos.
4515 * src/scan-gram.h (gram_last_string): Remove declaration.
4516 * src/scan-gram.l (last_string): Declare it static.
4518 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4520 Encapsulate code properties and related functionality for the various
4521 destructors, printers, and actions into a code_props structure and
4522 interface. This patch merely implements code_props in scan-code.h and
4523 scan-code.l. Future patches will rewrite other modules to use it.
4524 Discussed starting at
4525 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
4526 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
4527 consistently initialize const structs that have an empty location
4529 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
4530 to ensure consistency.
4531 * src/scan-code.h (code_props): New structure.
4532 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
4533 function, macro, and const global variable for initializing a
4534 code_props with no code.
4535 (code_props_plain_init, code_props_symbol_action_init,
4536 code_props_rule_action_init, code_props_translate_code): The rest of
4537 the new code_props functional interface. Among other things, the init
4538 functions set the code_props kind field so that
4539 code_props_translate_code will know whether to behave like
4540 translate_symbol_action, translate_rule_action, or translate_code.
4541 These old translate functions must remain until all other modules are
4542 updated to use the new code_props interface.
4543 (code_scanner_last_string_free): New function similar to
4544 gram_scanner_last_string_free.
4545 (code_scanner_free): Add documentation.
4546 * src/scan-code.l: Implement the new interface.
4547 (code_lex): Make it static, add a code_props* argument, and remove the
4549 (last_string): New static global similar to the one in scan-gram.l.
4550 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
4552 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
4553 code_props since Bison may one day use this information for destructors
4555 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
4556 (handle_action_dollar): Use symbol_list_n_get and set used flag
4557 directly since symbol_list_n_used_set is removed.
4558 (translate_action): Add a code_props* argument and remove the rule,
4559 action, and location arguments. Pass the code_props* on to code_lex.
4560 (translate_rule_action, translate_symbol_action, translate_code):
4561 Rewrite as wrappers around the new code_props interface.
4562 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
4563 it would eventually need to break the encapsulation of code_props.
4565 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4567 * etc/.cvsignore: New.
4569 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4571 Add maintainer-push-check to run maintainer-check using push parsing in
4572 place of pull parsing where available.
4573 * Makefile.am (maintainer-push-check): New.
4574 * data/bison.m4 (b4_use_push_for_pull_if): New.
4575 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
4576 appropriately based on their existing values.
4577 (yypush_parse): Don't print push-parser-specific diagnostics if push
4578 parsing is being used in place of pull parsing.
4579 * data/yacc.c: If push parsing should replace pull parsing, redirect to
4581 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
4582 variable, and insert b4_use_push_for_pull_flag into muscles.
4583 * tests/Makefile.am (maintainer-push-check): New.
4585 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4587 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
4588 (whether successful or failed) so that yypush_parse can be invoked
4589 again to start a new parse using the same yypstate.
4590 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
4591 check multiple yypull_parse invocations on the same yypstate. For pull
4592 mode, extend to check multiple yyparse invocations.
4593 (Exploding the Stack Size with Alloca): Extend to try with
4595 (Exploding the Stack Size with Malloc): Likewise.
4597 * tests/calc.at (Simple LALR Calculator): Don't specify
4598 %skeleton "push.c" since %push-pull-parser implies that now.
4599 * tests/headers.at (export YYLTYPE): Don't check for the push
4600 declarations. Otherwise, this test case can't be used to see if push
4601 mode can truly emulate pull mode.
4602 * tests/input.at (Torturing the Scanner): Likewise.
4603 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
4604 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
4605 AT_YACC_IF, which now includes the case of push mode since %skeleton
4606 need not be used for push mode. This will be more intuitive once
4607 push.c is renamed to yacc.c.
4609 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4611 For push mode, convert yyparse from a macro to a function, invoke yylex
4612 instead of passing a yylexp argument to yypull_parse, and don't
4613 generate yypull_parse or yyparse unless %push-pull-parser is declared.
4614 Discussed starting at
4615 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
4616 * data/bison.m4 (b4_pull_if): New.
4617 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
4618 * data/push.c: Improve M4 quoting a little.
4619 (b4_generate_macro_args, b4_parenthesize): Remove.
4620 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
4621 any time a pull parser is requested.
4622 Don't #define this as a wrapper around yypull_parse. Instead, when
4623 both push and pull are requested, make it a function that does that
4625 (yypull_parse): If there's a b4_prefix, #define this to
4626 b4_prefix[pull_parse] when both push and pull are requested.
4627 Don't define this as a function unless both push and pull are
4629 Remove the yylexp argument and hard-code yylex invocation instead.
4630 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
4632 * src/getargs.c (pull_parser): New global initialized to true.
4633 * getargs.h (pull_parser): extern it.
4634 * src/output.c (prepare): Insert pull_flag muscle.
4635 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
4636 (prologue_declaration): Set both push_parser and pull_parser = true for
4637 %push-pull-parser. Set push_parser = true and pull_parser = false for
4639 * src/scan-gram.l: Don't accept %push_parser as an alternative to
4640 %push-parser since there's no backward-compatibility concern here.
4641 Scan %push-pull-parser.
4642 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
4643 instead of %push-parser.
4644 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
4645 prototype it in the module that calls yyparse.
4646 * tests/input.at (Torturing the Scanner): Likewise.
4647 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
4649 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
4651 Update etc/bench.pl. Optimize push mode a little (the yyn change
4652 deserves most of the credit).
4653 * Makefile.am (SUBDIRS): Add etc subdirectory.
4654 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
4655 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
4656 yytoken, yyval, and yyloc declarations to...
4657 (yyparse or yypush_parse): ... here to improve performance. For
4658 yypush_parse invocations after the first, be sure to assign yyn its old
4660 (yypstate_new): Don't bother initializing the yyresult field since the
4661 initial value isn't used.
4662 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
4663 remove the #define that, in push mode, set it to yyps->NAME.
4664 * etc/Makefile.am: New.
4665 * etc/bench.pl: Remove and build it instead from...
4666 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
4667 "tests/bison" from the build directory by default rather than just
4668 invoking "bison" from $PATH.
4669 (calc_grammar): Update push parser code: don't declare yylval globally,
4670 don't define yyparse_wrapper, and don't #define yyparse.
4671 (bench_grammar): Update to check all working combinations of yacc.c,
4672 push.c, impure, pure, pull, and push.
4674 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4676 For push mode, add pull wrappers around yypush_parse.
4677 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
4678 (yypull_parse): New function wrapping yypush_parse.
4679 (yyparse): New #define wrapping yypull_parse.
4680 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
4682 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
4683 prototype yylex in the module that calls yyparse, and don't prototype
4684 yyparse there. Otherwise, the yyparse expansion won't compile.
4685 * tests/input.at (Torturing the Scanner): Likewise.
4687 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4689 Enable push parsers to operate in impure mode. Thus, %push-parser no
4690 longer implies %pure-parser. The point of this change is to move
4691 towards being able to test the push parser code by running the entire
4692 test suite as if %push-parser had been declared.
4693 * data/push.c (yypush_parse): For impure mode, remove the
4694 yypushed_char, yypushed_val, and yypushed_loc arguments.
4695 Instead, declare these as local variables initialized to the global
4696 yychar, yylval, and yylloc.
4697 For the first yypush_parse invocation only, restore the initial values
4698 of these global variables when it's time to read a token since they
4699 have been overwritten.
4700 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
4702 * tests/calc.at (Simple LALR(1) Calculator): Always declare
4703 %pure-parser along with %push-parser since this test case was designed
4704 for pure push parsers.
4705 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
4706 (AT_YACC_OR_PUSH_IF): New.
4707 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
4708 add a note that it's still wrong for some cases (as it has been for a
4710 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
4711 %push-parser no longer implies %pure-parser.
4713 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4715 Remove some unnecessary differences between the pull parser code and
4716 the push parser code. This patch enables yynerrs in push mode.
4717 * data/push.c: Reformat M4 a little.
4718 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
4719 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
4720 because push mode is on. Instead, if pure mode is on, move yynerrs
4722 (b4_declare_parser_state_variables): ... here.
4723 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
4724 to yyps->NAME so it can be used in yypush_parse.
4725 (yypush_parse): Don't omit uses of yynerrs in push mode.
4727 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4729 Fix bug such that the first pushed token's value and location are
4730 sometimes overwritten (sometimes by %initial-action) before being used.
4731 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
4732 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
4733 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
4734 more closely mimic the pull parser logic.
4735 Don't copy the pushed token to yychar, yylval, and yylloc until it's
4736 time to read a token, which is after any initialization of yylval and
4738 (gottoken): Rename label to...
4739 (yyread_pushed_token): ... for clarity and to avoid infringing on the
4742 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4744 Rearrange initialization of the parser state variables so that the
4745 skeleton doesn't have to have a copy for pull mode and another for push
4746 mode. This patch also fixes at least a bug such that yylloc was not
4747 initialized (with b4_location_initial_line and
4748 b4_location_initial_column) upon calling yypush_parse. However, that
4749 initialization now overwrites the first token's location;
4750 %initial-action assigning @$ already did the same thing, and both bugs
4751 will be fixed in a later patch.
4752 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
4753 (b4_declare_parser_state_variables): Remove initialization of yytoken,
4754 yyss, yyvs, yyls, and yystacksize.
4755 (yypstate_new): Remove initialization of some yypstate fields: yystate,
4756 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
4758 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
4759 yyps->NAME so it can be used in yypush_parse.
4760 (yyparse or yypush_parse): For yypush_parse, don't print the
4761 "Starting parse" diagnostic for invocations after the first.
4762 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
4763 yypush_parse, only do it for the first invocation.
4764 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
4765 initialization to occur in yypush_parse but only on the first
4768 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4770 * data/push.c: Add CPP guards around push parser declarations in both
4771 the header and the code file.
4772 In the code file, move the push parser declarations to the same place
4773 they appear in the header file.
4774 Clean up the M4 some, especially the inconsistent underquoting in
4775 some b4_c_function_def and b4_c_function_decl uses.
4777 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4779 Encapsulate the push parser state variables into an M4 macro so the
4780 push skeleton doesn't have to list them again for pull mode's yyparse.
4781 For push mode, remove yypush_parse's local equivalents of these
4782 variables to eliminate unnecessary copying between the two sets at
4783 run-time. This patch also fixes at least a bug related to multiple
4784 %initial-action invocations in push mode.
4785 * data/push.c (b4_declare_parser_variables): Rename to...
4786 (b4_declare_scanner_communication_variables): ... this for clarity and
4788 (b4_declare_yyparse_variables): Remove and move its contents to the one
4789 spot where it was invoked.
4790 (b4_declare_parser_state_variables): New macro containing the parser
4791 state variables required by push mode.
4792 (struct yypstate): Replace all fields but yynew with
4793 b4_declare_parser_state_variables.
4794 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
4795 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
4796 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
4797 (yyparse or yypush_parse): For yyparse in pull mode, replace local
4798 parser state variable declarations with
4799 b4_declare_parser_state_variables.
4800 Don't initialize parser state variables when calling yypush_parse since
4801 yypstate_new already does that.
4802 Invoke the user's initial action only upon the first yypush_parse
4804 Remove all code that copies between the local parser state variables
4807 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4809 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
4810 prevent a name collision in a future patch where these names will
4811 sometimes be #define'd.
4812 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
4813 since it no longer has the same name as the existing argument.
4814 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
4816 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
4817 and Joel E. Denny <jdenny@ces.clemson.edu>
4819 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
4820 that the argument is case-insensitive, and there's no `=' here.
4821 For the %skeleton entry, mention that %language is better.
4822 (Bison Options): Likewise for --language and --skeleton. Move the
4823 --skeleton entry so that the `Tuning the parser' section is sorted
4824 alphabetically on long options.
4825 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
4826 %language directive in detail here; cross-reference the %language
4827 documentation instead.
4828 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
4829 `%require "2.3b"' so that the example is always up-to-date.
4830 (Table of Symbols): Add entries for %language and %skeleton.
4831 * examples/extexi (normalize): Instead of replacing every %require
4832 argument with the current Bison version, just substitute for
4833 `@value{VERSION}'. This guarantees that we're testing what actually
4834 appears in the documentation.
4835 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
4836 rather than `@VERSION@'.
4838 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4840 * NEWS: Reword the %language news a bit, and put it earlier.
4842 * src/getargs.c (skeleton_arg): Last arg is now location const *.
4843 Rewrite to simplify the logic.
4844 (language_argmatch): Likewise.
4845 (program_name): We now own this var.
4846 * src/getargs.h (struct bison_language): Use char[] rather than
4849 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
4851 * src/complain.c (program_name): Remove decl; no longer needed.
4852 * src/main.c (program_name): Remove; now belongs to getargs.
4854 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
4856 * NEWS: Document %language.
4858 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
4860 * data/c-skel.m4, data/c++-skel.m4: New files.
4861 * data/glr.c: Complain on push parsers.
4863 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
4865 (Decl Summary): Document %language and %skeleton.
4866 (Command line): Document -L.
4868 * examples/extexi: Rewrite %require directive.
4869 * examples/calc++/Makefile.am: Pass VERSION to extexi.
4871 * src/files.c (compute_exts_from_gc): Look in language structure
4873 (compute_file_name_parts): Check whether .tab should be added.
4874 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
4875 (language, skeleton_arg, language_argmatch): New.
4876 (long_options): Add --language.
4877 (getargs): Use skeleton_arg, add -L/--language.
4878 * src/getargs.h: Include location.h.
4879 (struct bison_language, language, skeleton_arg, language_argmatch): New.
4880 * src/output.c (prepare): Pick default skeleton from struct language.
4881 Don't dispatch C skeletons here.
4882 * src/parse-gram.y (PERCENT_LANGUAGE): New.
4883 (prologue_declaration): Add "%language" rule, use skeleton_arg.
4884 * src/scan-gram.l ("%language"): New rule.
4886 * tests/calc.at: Test %skeleton and %language.
4887 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
4888 (AT_GLR_IF): Look for %skeleton "glr.cc".
4889 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
4890 (AT_YACC_IF): Reject %language.
4892 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4894 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
4895 since it wasn't used; only the typedef name 'semantic_type' is needed.
4896 Also, omit trailing white space.
4898 * bootstrap: Sync from coreutils.
4899 (gnulib_extra_files): Add build-aux/announce.gen.
4900 (slurp): Adjust .gitignore files like .cvsignore files.
4901 * build-aux/announce-gen: Remove from CVS, since bootstrap
4904 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
4906 Make %push-parser imply %pure-parser. This fixes several bugs; see
4907 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
4908 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
4910 * data/push.c: Don't bother testing b4_push_if when deciding whether
4911 to expand b4_declare_parser_variables globally.
4912 (yypush_parse): Likewise in here.
4914 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
4915 (yy_reduce_print): Reformat M4 for readability.
4917 2006-12-15 Bob Rossi <bob@brasko.net>
4918 and Joel Denny <jdenny@ces.clemson.edu>
4920 * data/push.c (yypstate): Add typedef, and update all uses of
4921 struct yypstate to just yypstate.
4922 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
4924 2006-12-14 Bob Rossi <bob@brasko.net>
4926 * data/push.c (yypush_parse): Declare prototype regardless of
4929 2006-12-14 Bob Rossi <bob@brasko.net>
4931 * data/push.c (yyparse): Remove the prototype and the #define when in
4934 2006-12-13 Bob Rossi <bob@brasko.net>
4936 * data/push.c (yypstate_init): Rename to...
4937 (yypstate_new): ... this and use b4_c_function_def.
4938 (yypstate_delete): New.
4939 (yypush_parse): Change parameters yynval and yynlloc to be const.
4940 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
4941 yypstate_delete functions.
4943 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
4945 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
4946 strange test case titles. Reported by Bob Rossi.
4948 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
4950 * TODO: Add pointer to Sylvain Schmitz's work on static detection
4951 of potential ambiguities in GLR grammers.
4953 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
4955 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
4956 `bison ', use m4_index instead of m4_substr since chopping up a string
4957 containing M4-special characters causes problems here.
4959 Fix a couple of bugs related to special characters in user-specified
4960 file names, and make it easier for skeletons to compute output file
4961 names with the same file name prefix as Bison-computed output file
4963 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
4964 b4_parser_file_name and b4_spec_defines_file instead of
4965 @output_parser_name@ and @output_header_name@, which are now redundant.
4966 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
4967 b4_parser_file_name, b4_spec_defines_file, and the new
4968 @basename(FILENAME@) instead of @output_parser_name@ and
4969 @output_header_name@, which inappropriately escaped the file names as
4971 * src/files.c (all_but_ext): Remove static qualifier.
4972 (compute_output_file_names): Move `free (all_but_ext)' to...
4973 (output_file_names_free): ... here since all_but_ext is needed later.
4974 * src/files.h (all_but_ext): Extern.
4975 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
4976 exactly what MUSCLE_INSERT_STRING used to do.
4977 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
4978 characters are escaped properly.
4979 * src/output.c (prepare): Define muscle file_name_all_but_ext as
4981 For pkgdatadir muscle, maintain previous functionality by using
4982 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
4983 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
4984 digraphs would never be expanded. Hopefully no one has M4-special
4985 characters in his Bison installation path.
4986 * src/scan-skel.l: Don't parse @output_header_name@ and
4987 @output_parser_name@ anymore since they're now redundant.
4988 In @output, use decode_at_digraphs.
4989 Parse a new @basename command that invokes last_component.
4990 (decode_at_digraphs): New.
4991 (BASE_QPUTS): Remove unused.
4992 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
4993 (Output file name): New tests.
4995 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
4997 Warn about output files that are generated by the skeletons and that
4998 conflict with other output files.
4999 * data/glr.c: Don't generate the header file here when glr.cc does.
5000 * src/files.c (file_names, file_names_count): New static globals.
5001 (compute_output_file_names): Invoke output_file_name_check for files
5002 not generated by the skeletons and remove existing checks.
5003 (output_file_name_check): New function that warns about conflicting
5005 (output_file_names_free): Free file_names.
5006 * src/files.h (output_file_name_check): Declare.
5007 * src/scan-skel.l: Invoke output_file_name_check for files generated by
5009 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
5010 (Conflicting output files): New tests.
5012 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5014 * doc/bison.texinfo: Fix a couple of typos.
5016 2006-12-08 Bob Rossi <bob@brasko.net>
5018 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
5020 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
5022 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
5023 (yypush_parse): Rename yypvars argument to yyps and remove redundant
5025 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
5026 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
5028 2006-12-07 Bob Rossi <bob@brasko.net>
5029 and Joel Denny <jdenny@ces.clemson.edu>
5031 * data/push.c (yypvarsinit): Change return type from void* to struct
5032 yypvars*. No longer cast to void* on return.
5033 (struct yypvars): Remove yylen since it need not be remembered between
5034 yypushparse invocations.
5035 (yypushparse): Don't copy between yylen and pv->yylen.
5037 2006-12-05 Bob Rossi <bob@brasko.net>
5039 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
5040 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
5041 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
5042 (struct yypvars): Remove b4_declare_parser_variables.
5043 (yypvarsinit): Remove init code for removed variables.
5044 (global scope): Do not declare b4_declare_parser_variables if
5046 (yypushparse): Add b4_declare_parser_variables.
5047 Init new local variables, and remove init code for removed
5050 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
5051 and yyparse for other modes.
5052 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
5053 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
5054 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
5055 (AT_PURE_LEX_IF): True if pure or push parser.
5057 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>

5133 grammar is maintained with Bison's highest standards.

5138 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
5139 later. Reported by Paul Eggert in
5140 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
5141 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
5142 * src/scan-code.l (translate_action): Don't bother invoking
5143 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
5144 (code_scanner_free): Instead of invoking
5145 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

5153 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
5154 has been called previously for the same key.

5158 could potentially be NULL when value is not.

5195 * src/muscle_tab.c: Likewise.
5196 (muscle_entry): Make the value char const *,
5197 and add a new storage member that is char * and can be freed.
5198 (muscle_entry_free): New private function.
5199 (muscle_init): Use it instead of free.
5200 (muscle_insert, muscle_grow): Update and use new storage member.
5201 (muscle_code_grow): Free the string passed to muscle_grow
5202 since it's not needed anymore.
5203 * src/parse-gram.y (%union): Make `chars' member a `char const *', and

5218 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
5219 expecting a non-zero exit status sets --leak-check=summary and
5220 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
5221 this case, and we don't want to hear about it.
5223 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
5225 * bootstrap (runtime-po/Makevars): Derive from po/Makevars

5242 declarations): Run tests with and without --warnings=midrule-values.
5244 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather

5266 empty subargument list. For example: `bison --warnings= parser.y'.
5268 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
5270 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
5271 the parser header file so that gcc doesn't warn.
5273 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>

5324 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
5325 like $@n instead of just @n so that the default %destructor/%printer
5326 logic doesn't see them as user-defined symbols.
5327 (symbol_is_dummy): Check for both forms of the name.
5328 * src/reader.c (packgram): Remove the `$' from each midrule symbol
5329 name for which the midrule value is referenced in any action.

5341 all actions have already been scanned in order to set `used' flags.
5342 Otherwise, checking that a midrule's $$ is set will not always work
5343 properly because the midrule check must forward-reference the midrule's

5472 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
5473 variable was sometimes used without being initialized. This
5474 messed up the installation of the INSTALL file in some cases.

5478 * bootstrap (usage, main program, symlink_to_gnulib): Add option
5479 --copy. Inspired by a suggestion from Bruno Haible.
5481 2006-10-03 Jim Meyering <jim@meyering.net>

5486 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
5488 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

5634 to copies-of-gnulib.
5635 (cp_mark_as_generated, slurp, gnulib_files):
5636 Avoid making a copy if it's the same as the old version.
5637 (gnulib_files): Add support for this variable (used by Bison).
5639 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5641 * src/getargs.c (usage): Rework to use conventions similar to
5642 coreutils, to make translation a bit easier and the code a bit
5643 smaller. Problem reported by Tim Van Holder.
5645 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
5647 Use some of gnulib's new modules, taken from coreutils.
5649 * bootstrap: Sync from coreutils, except add support for gnulib_files.
5650 * bootstrap.conf: New file.
5651 (gnulib_modules): Add configmake, inttypes, unistd.
5652 (XGETTEXT_OPTIONS): Add complain, complain_at,
5653 fatal, fatal_at, warn, warn_at, unexpected_end.
5654 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
5655 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
5657 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
5659 (GNULIB_AUTOCONF_SNIPPET): Remove.
5660 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
5662 * lib/.cvsignore: Add inttypes_.h.
5663 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
5664 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
5665 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
5666 no-longer-necessary initializations.
5667 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
5668 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
5669 use the unistd module.
5670 * src/system.h: Likewise.
5671 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
5672 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
5673 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
5674 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
5675 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
5676 * src/system.h: Include inttypes.h unconditionally, now that we
5677 use the inttypes module. Don't bother to include stdint.h, since
5678 inttypes.h now does that for us.
5679 (LOCALEDIR): Remove, now that we use the configmake module.
5680 * src/getargs.c: Include configmake.h.
5681 * src/main.c: Likewise.
5682 * src/output.c: Likewise.
5683 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
5684 not from $abs_top_builddir, since config.h moved.
5687 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
5688 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
5690 * src/parse-gram.y (symbol_declaration): Don't put statements
5691 before declarations; it's not portable to C89.
5692 * src/scan-code.l (handle_action_at): Likewise.
5694 * src/scan-code.l: Always initialize braces_level; the old code
5695 left it uninitialized and therefore had undefined behavior.
5697 Don't attempt to redefine 'assert', since it runs afoul of
5698 systems where standard headers (mistakenly) include <assert.h>.
5699 Instead, define and use our own alternative, called 'aver'.
5700 * src/reader.c: Don't include assert.h, since we no longer
5702 * src/scan-code.l: Likewise.
5703 * src/system.h (assert): Remove, replacing with....
5704 (aver): New function, taking a bool arg. All uses changed.
5705 * src/tables.c (pack_vector): Ensure that aver arg is bool,
5706 not merely an integer.
5708 2006-09-15 Bob Rossi <bob@brasko.net>
5710 Add support for push parsing. Based on the original work of
5711 Odd Arild Olsen <oao@fibula.no>.
5712 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
5713 * data/c.m4 (YYPUSH): New.
5714 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
5715 * data/push.c: New file.
5716 * src/getargs.c (push_parser): New var.
5717 * src/getargs.h (push_parser): New declaration.
5718 * src/output.c (prepare): Add macro insertion of `push_flag'.
5719 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
5720 (prologue_declaration): Parse %push-parser.
5721 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
5722 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
5723 list of removed lines from the traces observed.
5724 (AT_CHECK_CALC_LALR): Added push parser tests.
5726 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
5728 * NEWS: Version 2.3a.
5729 * configure.ac (AC_INIT): Likewise.
5731 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
5732 "#define YYSTYPE int" that caused "make maintainer-check" to fail
5733 due to header ordering dependencies. I don't know why the #define
5736 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
5737 runtime cost when YYDEBUG is not defined, and so that some tests
5738 that used to fail now work. Problem and initial suggestion by
5740 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
5741 * data/glr.cc (b4_parser_class_name):
5742 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
5743 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
5744 (yydebug_) [YYDEBUG]: New member.
5745 (yycdebug_): Now defined only if YYDEBUG.
5746 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
5747 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
5748 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
5750 (debug_stream, set_debug_stream, debug_level, set_debug_level):
5751 Define only if YYDEBUG.
5752 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
5754 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
5755 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
5756 AT_CHECK_CALC_GLR_CC that are working now.
5758 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
5760 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
5761 We don't need them in glr.cc, and glr.c defines them.
5762 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
5763 assumes that defining it to anything is the same as defining
5764 it to 1. Problem reported by Paolo Bonzini.
5766 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
5768 * data/c.m4 (b4_null, b4_case): Define.
5769 * src/output.c (prepare_symbols): Use b4_null.
5770 (user_actions_output): Use b4_case.
5772 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
5774 * data/glr.c (b4_shared_declarations): Put start-header first,
5775 before any #includes that we generate, so that feature-test
5776 macros work. Problem reported by Michael Deutschmann in
5777 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
5778 * data/lalr1.cc: Likewise.
5779 * doc/bison.texinfo (Prologue): Document that feature-test macros
5780 should be defined before any Bison declarations.
5781 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
5782 that depend on location.hh after, not before, Bison decls, since
5783 we now include location.hh after the first user prologue.
5785 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
5786 Sander Brandenburg in
5787 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
5788 Also, fix minor white space and comment issues.
5789 (Prologue): Mention that it's better to define feature-test macros
5790 before Bison declarations. Problem reported by Michael Deutschmann.
5792 * README-cvs: Fix typo: "&" should be "&&". Problem reported
5794 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
5795 This adjusts to recent gnulib changes.
5797 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
5799 Finish implementation of per-type %destructor/%printer. Discussed
5801 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
5803 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
5804 * NEWS (2.3+): Add a description of this feature to the default
5805 %destructor/%printer description.
5806 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
5807 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
5808 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
5809 list node contains a semantic type.
5810 * src/symtab.c, src/symtab.h: Extend with a table that associates
5811 semantic types with their %destructor's and %printer's.
5812 (semantic_type_from_uniqstr, semantic_type_get,
5813 semantic_type_destructor_set, semantic_type_printer_set): New functions
5814 composing the public interface of that table.
5815 (symbol_destructor_get, symbol_destructor_location_get,
5816 symbol_printer_get, symbol_printer_location_get): If there's no
5817 per-symbol %destructor/%printer, look up the per-type before trying
5819 * tests/actions.at (Per-type %printer and %destructor): New test case.
5820 * tests/input.at (Default %printer and %destructor redeclared):
5821 Extend to check that multiple occurrences of %symbol-default in a
5822 single %destructor/%printer declaration is an error.
5823 (Per-type %printer and %destructor redeclared, Unused values with
5824 per-type %destructor): New test cases.
5826 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
5828 Require default %destructor/%printer to be declared using
5829 %symbol-default instead of an empty symbol list, and start working on
5830 new per-type %destructor/%printer. Discussed at
5831 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
5832 * NEWS (2.3+): Add %symbol-default to example.
5833 * bison.texinfo (Freeing Discarded Symbols): Likewise.
5834 (Table of Symbols): Add entry for %symbol-default.
5835 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
5836 (generic_symlist, generic_symlist_item): New nonterminals for creating
5837 a list in which each item is a symbol, semantic type, or
5839 (grammar_declaration): Use generic_symlist in %destructor and %printer
5840 declarations instead of symbols.1 or an empty list.
5841 (symbol_declaration, precedence_declaration, symbols.1): Update actions
5842 for changes to symbol_list.
5843 * src/reader.c: Update for changes to symbol_list.
5844 * src/scan-code.l: Likewise.
5845 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
5846 * src/symlist.c, src/symlist.h: Extend such that a list node may
5847 represent a semantic type or a %symbol-default in addition to just an
5848 ordinary symbol. Add switched functions for setting %destructor's and
5850 * tests/actions.at, tests/input.at: Add %symbol-default to all default
5851 %destructor/%printer declarations.
5853 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
5855 Whether the default %destructor/%printer applies to a particular symbol
5856 isn't a question of whether the user *declares* that symbol (in %token,
5857 for example). It's a question of whether the user by any means
5858 *defines* the symbol at all (by simply using a char token, for
5859 example). $end is defined by Bison whereas any other token with token
5860 number 0 is defined by the user. The error token is always defined by
5861 Bison regardless of whether the user declares it with %token, but we
5862 may one day let the user define error as a nonterminal instead.
5863 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
5864 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
5865 the meaning of "user-defined".
5866 * tests/actions.at (Default %printer and %destructor for user-declared
5867 end token): Rename to...
5868 (Default %printer and %destructor for user-defined end token): ...
5871 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
5872 computation of whether to apply the default, don't maintain a list of
5873 every Bison-defined symbol. Instead, just check for a first character
5874 of '$', which a user symbol cannot have, and check for the error token.
5876 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
5878 Don't apply the default %destructor or %printer to the error token,
5879 $undefined, or $accept. This change fits the general rule that the
5880 default %destructor and %printer are only for user-declared symbols,
5881 and it solves several difficulties that are described in the new test
5883 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
5884 * tests/actions.at (Default %printer and %destructor are not for error
5885 or $undefined, Default %printer and %destructor are not for $accept):
5888 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
5890 Allow %start after the first rule.
5891 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
5892 when parsing the first rule.
5893 (check_and_convert_grammar): Search for it here after all grammar
5894 declarations have been parsed. Skip midrules, which have dummy LHS
5896 * src/symtab.c (symbol_is_dummy): New function.
5897 * src/symtab.h (symbol_is_dummy): Declare it.
5898 * tests/input.at (%start after first rule): New test.
5900 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
5902 Redo some of the previous commit: add back the ability to use
5903 non-aliased/undeclared string literals since it might be useful to
5904 those declaring %token-table.
5905 * src/reader.c (check_and_convert_grammar): Undo changes in previous
5906 commit: don't worry about complaints from symbols_pack.
5907 * src/symtab.c (symbol_new, symbol_class_set,
5908 symbol_check_alias_consistency): Undo changes in previous commit: count
5909 each string literal as a new symbol and token, assign it a symbol
5910 number, and don't complain about non-aliased string literals.
5911 (symbols_pack): Since symbol_make_alias still does not decrement symbol
5912 and token counts but does still set aliased tokens to the same number,
5913 symbol_pack_processor now leaves empty slots in the symbols array.
5915 * tests/regression.at (Undeclared string literal): Remove test case
5916 added in previous commit since non-aliased string literals are allowed
5918 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
5919 remove unnecessary string literal declarations.
5920 * tests/sets.at (Firsts): Likewise.
5922 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
5924 Don't allow an undeclared string literal, but allow a string literal to
5925 be used before its declaration.
5926 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
5927 symbols_pack complained.
5928 * src/symtab.c (symbol_new): Don't count a string literal as a new
5930 (symbol_class_set): Don't count a string literal as a new token, and
5931 don't assign it a symbol number since symbol_make_alias does that.
5932 (symbol_make_alias): It's not necessary to decrement the symbol and
5933 token counts anymore. Don't assume that an alias declaration occurs
5934 before any uses of the identifier or string, and thus don't assert that
5935 one of them has the highest symbol number so far.
5936 (symbol_check_alias_consistency): Complain if there's a string literal
5937 that wasn't declared as an alias.
5938 (symbols_pack): Bail if symbol_check_alias_consistency failed since
5939 symbol_pack asserts that every token has been assigned a symbol number
5940 although undeclared string literals have not.
5941 * tests/regression.at (String alias declared after use, Undeclared
5942 string literal): New test cases.
5943 (Characters Escapes, Web2c Actions): Declare string literals as
5945 * tests/sets.at (Firsts): Likewise.
5947 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
5949 In the grammar scanner, STRING_FINISH unclosed constructs and return
5950 them to the parser in order to improve error messages.
5951 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
5952 SC_BRACED_CODE, SC_PROLOGUE): Implement.
5953 * tests/input.at (Unclosed constructs): New test case.
5954 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
5957 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
5960 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
5962 Handle string aliases for character tokens correctly.
5963 * src/symtab.c (symbol_user_token_number_set): If the token has an
5964 alias, check and set its alias's user token number instead of its own,
5965 which is set to indicate the alias. Previously, every occurrence of
5966 the character token in the grammar overwrote that alias indicator with
5968 * tests/input.at (String aliases for character tokens): New test.
5970 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
5972 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
5974 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
5976 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
5977 to prevent failures when building on older platforms.
5978 Check for autopoint failure.
5979 Set XGETTEXT_OPTIONS to values that check for C format strings,
5980 so that translators are warned about them (this also helps
5981 prevent core dumps).
5983 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
5984 function, since it simplifies our code a bit.
5986 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
5987 rather than -W, so we don't get bogus warnings about sign comparisons.
5988 Add -Wpointer-arith, since that warning is useful (it reports code
5989 that does not conform to C89 and that some compilers reject).
5990 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
5991 since it's no longer needed.
5993 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
5995 Clean up scanners a bit.
5996 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
5997 definitions so gcc won't warn when obstack_for_string is unused.
5998 * src/scan-code.l: config.h and system.h are already #include'd by
5999 scan-code-c.c, so get rid of them here.
6000 * src/scan-gram.l: Likewise.
6001 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
6002 definitions rather than duplicating the rest of it.
6003 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
6005 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
6007 Suppress signed/unsigned comparison warnings for yycheck.
6008 * data/c.m4 (b4_safest_int_type): New macro.
6009 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
6010 a signed int type, cast it to b4_safest_int_type first.
6011 * data/yacc.c: Likewise.
6012 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
6015 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
6017 * doc/bison.texinfo: Fix some typos.
6019 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
6021 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
6022 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
6024 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
6025 the latest gnulib does this a different way.
6026 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
6027 translation was patched, so stop omitting it.
6029 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6031 Enable declaration of default %printer/%destructor. Make the parser
6032 use these for all user-declared grammar symbols for which the user does
6033 not declare a specific %printer/%destructor. Thus, the parser uses it
6034 for token 0 if the user declares it but not if Bison generates it as
6035 $end. Discussed starting at
6036 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
6037 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
6039 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
6040 * NEWS (2.3+): Mention.
6041 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
6042 declare a %destructor for a mid-rule's semantic value. It's just
6043 impossible to declare one specific to it.
6044 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
6045 code. Describe default %destructor form.
6046 * src/parse-gram.y (grammar_declaration): Parse default
6047 %printer/%destructor declarations.
6048 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
6049 and symbol_destructor_location_get rather than accessing the destructor
6050 and destructor_location members of struct symbol.
6051 (symbol_printers_output): Likewise but for %printer's.
6052 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
6054 * src/symtab.c (default_destructor, default_destructor_location,
6055 default_printer, default_printer_location): New static global
6056 variables to record the default %destructor and %printer.
6057 (symbol_destructor_get, symbol_destructor_location_get,
6058 symbol_printer_get, symbol_printer_location_get): New functions to
6059 compute the appropriate %destructor and %printer for a symbol.
6060 (default_destructor_set, default_printer_set): New functions to set the
6061 default %destructor and %printer.
6062 * src/symtab.h: Prototype all those new functions.
6063 * tests/actions.at (Default %printer and %destructor): New test to
6064 check that the right %printer and %destructor are called, that they're
6065 not called for $end, and that $$ and @$ work correctly.
6066 (Default %printer and %destructor for user-declared end token): New
6067 test to check that the default %printer and %destructor are called for
6068 a user-declared end token.
6069 * tests/input.at (Default %printer and %destructor redeclared, Unused
6070 values with default %destructor): New tests to check related grammar
6071 warnings and errors.
6073 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6075 Clean up handling of %destructor for the end token (token 0).
6076 Discussed starting at
6077 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
6079 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
6081 Make the skeletons consistent in how they pop the end token and invoke
6083 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
6084 state, which has token number 0, since this would invoke the
6085 %destructor for the end token.
6086 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
6087 until after shifting the end token, or else it won't be popped.
6088 * data/yacc.c (yyparse): Likewise.
6090 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
6091 it's the end token. Upon termination, destroy an unshifted lookahead
6092 even when it's the end token.
6093 * data/lalr1.cc (yy::parser::parse): Likewise.
6094 * data/yacc.c (yyparse): Likewise.
6096 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
6097 value warnings for the end token when the user gives the end token a
6100 * tests/actions.at (Printers and Destructors): Test all the above.
6102 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
6104 Update to latest gnulib and gettext versions.
6105 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
6107 (gnulib_files): Add m4/warning.m4. Don't worry about files
6108 overwritten by autopoint.
6109 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
6110 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
6112 Don't use autoreconf; instead, invoke autopoint etc. by hand,
6113 so that we can remove the intl files at a better time.
6114 (intl_files_to_remove): Remove aclocal.m4, since it gets
6115 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
6116 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
6117 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
6118 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
6119 Remove datarootdir hack; no longer needed.
6120 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
6121 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
6122 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
6124 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
6125 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
6127 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
6129 * bootstrap: Adjust to today's change to gnulib-tool by invoking
6130 it with --assume-autoconf='latest-stable'.
6132 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
6134 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
6135 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
6137 * src/muscle_tab.h (muscle_grow): Replace the header comments with
6138 those from muscle_tab.c since the old ones are misleading.
6140 2006-07-13 Akim Demaille <akim@epita.fr>
6142 Support %define "KEY" {VALUE}.
6143 * src/scan-code.h, src/scan-code.l (translate_action)
6144 (translate_rule_action, translate_symbol_action, translate_code):
6145 Return char *, not const char *.
6146 * src/parse-gram.y (declaration): Rename as...
6147 (prologue_declaration): this.
6148 (string_content): Remove this nonterminal, use STRING.
6149 (braceless, content, content.opt): New nonterminal.
6151 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
6153 * src/scan-gram.l (getargs.h): Don't include it.
6155 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
6157 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
6158 rather than a for-loop that declares a local bool variable. This
6159 should work around a compatibility problem with a Cray x1e C++
6160 compiler reported by Hung Nguyen in
6161 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
6162 The for-loop was introduced in the 2004-11-17 change but I don't
6163 know why it was needed.
6165 2006-07-12 Akim Demaille <akim@epita.fr>
6167 * data/c.m4: Comment changes.
6169 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
6171 * src/complain.c (error_message, ERROR_MESSAGE): New.
6173 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
6174 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
6176 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
6178 * NEWS: Instead of %union, you can define and use your own union type
6179 YYSTYPE if your grammar contains at least one <type> tag.
6180 Your YYSTYPE need not be a macro; it can be a typedef.
6181 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
6182 (Union Decl, Decl Summary): Document this.
6183 * data/glr.c (YYSTYPE): Implement this.
6184 * data/glr.cc (YYSTYPE): Likewise.
6185 * data/lalr1.cc (YYSTYPE): Likewise.
6186 * data/yacc.c (YYSTYPE): Likewise.
6187 * src/output.c (prepare): Output tag_seen_flag.
6188 * src/parse-gram.y (declaration, grammar_declaration):
6189 Use 'union_seen' rather than 'typed' to determine whether
6190 %union has been seen, since grammars can now be typed without
6192 (symbol_declaration, type.opt, symbol_def):
6193 Keep track of whether a tag has been seen.
6194 * src/reader.c (union_seen, tag_seen): New vars.
6196 * src/reader.h (union_seen, tag_seen, typed): Likewise.
6197 * src/scan-code.l (untyped_var_seen): New variable.
6198 (handle_action_dollar): Adjust to above changes.
6199 (handle_action_dollar, handle_action_at):
6200 Improve overflow checking for outlandish numbers.
6201 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
6202 avoid new diagnostics generated by above changes.
6203 * tests/regression.at (YYSTYPE typedef): Add test to check
6204 for type tags without %union.
6206 * src/symlist.c (symbol_list_length): Return int, not unsigned
6207 int, since callers expect int. This may need to get revisited
6208 once we have proper integer overflow checking.
6210 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
6211 object is now static.
6213 * src/getargs.c (flags_argmatch): Return void, not int,
6214 to pacify ./configure --enable-gcc-warnings.
6216 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
6217 since last_string is already defined to FLEX_PREFIX (last_string).
6219 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
6221 Implement --warnings/-W.
6222 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
6224 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
6226 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
6227 (warnings_args, warnings_types): New.
6228 (getargs, short_options, long_options): Accept -W/--warnings.
6229 Sort the options by alphabetical order, upper case letter right
6230 before its lower case.
6232 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
6234 Change %merge result type clash warnings to errors. Discussed at
6235 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
6236 * src/reader.c (record_merge_function_type): Use complain_at.
6237 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6238 declared later): Update test case results.
6240 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
6242 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
6243 to be in alphabetical order.
6244 (trace_args): Spelling fixes.
6246 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
6248 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
6249 so they don't collide with user-defined macros.
6250 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
6251 this was never guaranteed, and now that we're using gnulib stdint,
6252 which defines int_fast16_t to long int, the problem is exposed.
6254 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
6256 * data/c.m4 (b4_basename): Simplify a bit, since we don't
6257 need the full POSIX semantics (and weren't implementing them
6260 Adjust to Autoconf 2.60 and today's gnulib.
6261 * bootstrap (gnulib_modules): Add stdint.
6262 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
6263 no longer copies it.
6264 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
6265 since stdint needs the former and wcwidth (which is now required
6266 by mbswidth) needs the latter.
6267 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
6268 work around a compatibility glitch between gettext 0.14.6 and
6270 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
6271 Do not check for uintptr_t, since new stdint module does the right
6273 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
6274 Add stdint.h, stdint_.h, wcwidth.h.
6275 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
6276 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
6277 stdint.m4, wchar_t.m4, wcwidth.m4.
6278 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
6279 usual order for ../lib/*.h files.
6280 (file_name_split): Use last_component, not base_name, to adjust
6282 * src/parse-gram.h: Include <strverscmp.h> in the usual order
6283 for ../lib/*.h files.
6284 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
6285 Define unconditionally, since we now assume the stdint module.
6286 * src/scan-skel.l: Include <dirname.h>.
6287 (BASE_QPUTS): Use last_component, not base_name.
6288 * src/system.h: Include <unlocked-io.h> in the usual order
6289 for ../lib/*.h files. Include <stdint.h> unconditionally,
6290 since we now use the stdint module.
6291 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
6292 HAVE_UINTPTR_T, since we now use the stdint module.
6293 (base_name): Remove decl, since files now include <dirname.h>
6296 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
6298 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
6300 * data/yacc.c, data/glr.c, data/location.cc: Use them.
6301 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
6303 * tests/calc.at: Adjust.
6305 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
6307 * data/c.m4 (b4_basename): New.
6308 (b4_syncline): Also output the location of its invocation (from
6310 (b4_user_action, b4_define_user_action, b4_user_actions)
6311 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
6312 (b4_user_stype): New.
6313 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
6315 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6317 In the grammar file, the first column is 1 not 0 on the first line as
6318 on every other line.
6319 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
6320 * tests/input.at (Torturing the Scanner): Update output.
6322 * src/scan-gram.l (scanner_cursor): Declare it static.
6324 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6326 In warnings, say "previous declaration" rather than "first
6328 * src/symtab.c (redeclaration): Do that here.
6329 * src/reader.c (record_merge_function_type): In the case of a result
6330 type clash, report the previous declaration rather than the very first
6331 one in the grammar file.
6332 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6333 declared later): Add a third declaration to check this behavior.
6334 * tests/input.at (Incompatible Aliases): Update output.
6336 2006-06-27 Akim Demaille <akim@epita.fr>
6338 * doc/Doxyfile.in: New.
6339 * doc/Makefile.am: Use it.
6340 * src/lalr.h, src/symtab.h: Initial doxygenation.
6342 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6344 Don't miss %merge result type warnings just because the LHS types are
6345 declared after the %merge. This continues the effort of the previous
6347 * src/reader.c (get_merge_function): Don't set the merger type yet.
6348 (record_merge_function_type): New function for setting the merger type
6349 and checking for clashes.
6350 (grammar_current_rule_merge_set): Set the location of the %merge for
6352 (packgram): Invoke record_merge_function_type for each rule now that
6353 all symbol type declarations have been parsed.
6354 * src/reader.h (merger_list.type_declaration_location): New member
6355 storing the location of the first %merge from which the type for this
6356 merging function was derived.
6357 * src/symlist.h (symbol_list.merger_declaration_location): New member
6358 storing the location of a rule's %merge, if any.
6359 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6360 declared later): New test to catch the error fixed by the above patch.
6362 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6364 Get action warnings (grammar_rule_check) right even when symbol
6365 declarations appear after the rules. Discussed at
6366 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
6368 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
6369 Don't mistake the type of $$ in a midrule to be that of its parent
6371 * src/reader.c (grammar_current_rule_end): Don't invoke
6372 grammar_rule_check yet since not all symbol declarations may have been
6374 (grammar_midrule_action): Likewise.
6375 Don't record whether the midrule's $$ has been used yet since actions
6376 haven't been translated yet.
6377 Record the midrule's parent rule and its RHS index within the parent
6379 (grammar_current_rule_action_append): Don't translate the action yet
6380 since not all symbol declarations may have been parsed yet and, thus,
6381 warnings about types for $$, $n, @$, and @n can't be reported yet.
6382 (packgram): Translate the action and invoke grammar_rule_check now that
6383 all symbol declarations have been parsed.
6384 * src/scan-code.l (handle_action_dollar): Now that this is invoked
6385 after parsing the entire grammar file, the symbol list here in the case
6386 of a midrule is actually the midrule's empty RHS, so reference its
6387 parent rule's RHS where necessary.
6388 On the other hand, now that you can already know it's a midrule, you
6389 aren't forced to think $$ has the same type as its parent rule's $$.
6390 (handle_action_at): In the case of a midrule, reference the parent rule
6392 * src/symlist.c (symbol_list_new): Initialize new midrule-related
6394 (symbol_list_length): Now that this is invoked after all rules have
6395 been parsed, a NULL symbol (rather than a NULL symbol list node)
6396 terminates a rule. symbol_list_print already does this correctly.
6397 * src/symlist.h (symbol_list.midrule_parent_rule,
6398 symbol_list.midrule_parent_rhs_index): New members so that midrules can
6399 remember their relationships with their parents.
6400 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
6401 fixed by the above patch.
6402 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
6404 (Unused values): ... this old test case and...
6405 (Unused values before symbol declarations): ... this new test case.
6406 This one is the same as `Unused values' except that all symbol
6407 declarations appear after the rules in order to catch the rest of the
6408 errors fixed by the above patch.
6410 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6413 * src/reader.c (current_rule): Declare it static since it's no longer
6414 used outside this file.
6415 (grammar_current_rule_action_append): Remove redundant arguments from
6416 translate_rule_action invocation.
6417 * src/reader.h (current_rule): Remove this unused extern.
6418 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
6419 * src/scan-code.l (translate_rule_action): Likewise.
6421 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
6423 Clean up yesterday's patch.
6424 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
6426 * src/reader.c (grammar_current_rule_action_append): ... here for
6427 consistency with grammar_current_rule_symbol_append.
6428 * tests/regression.at (Braced code in declaration in rules section):
6429 Make yyerror and yylex static as usual.
6431 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
6433 Fix bug that mistakes braced code in a declaration in the rules section
6434 to be a rule action. Mentioned at
6435 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
6436 * src/scan-gram.l: Move midrule action detection from the start of the
6437 scanning of any braced code to...
6438 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
6439 action. For readability, use $2 and @2 rather than the equivalent
6441 * tests/regression.at (Braced code in declaration in rules section):
6442 New test to catch the error fixed by the above patch.
6444 Work on code readability some.
6445 * src/scan-code.l (current_rule): Get rid of this misleading and
6446 redundant declaration: it's actually extern'ed in reader.h.
6447 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
6448 translate_action): Add a rule argument and use it instead of the global
6450 (translate_rule_action): This already receives current_rule through an
6451 argument, so pass it on to translate_action instead of assigning
6452 current_rule to current_rule.
6453 (translate_symbol_action, translate_code): Pass rule = NULL to
6456 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
6458 Rename %before-definitions to %start-header and %after-definitions to
6459 %end-header. Don't use these declarations to separate pre-prologue
6460 blocks from post-prologue blocks. Add new order-independent
6461 declarations %before-header and %after-header as alternatives to the
6462 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
6463 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
6464 * NEWS (2.3+): Update for these changes.
6465 * data/glr.c (b4_before_definitions): Update to...
6466 (b4_start_header): ... this.
6467 (b4_after_definitions): Update to...
6468 (b4_end_header): ... this.
6469 * data/glr.cc: Likewise.
6470 * data/lalr1.cc: Likewise.
6471 * data/yacc.c: Likewise.
6472 * doc/bison.texinfo (The prologue): Update names, and replace remaining
6473 prologue blocks with %*-header declarations.
6474 (Calc++ Parser): Likewise.
6475 (Decl Summary): Update names.
6476 (Table of Symbols): Update description.
6477 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
6478 (PERCENT_END_HEADER): ... this.
6479 (PERCENT_BEFORE_DEFINITIONS): Update to...
6480 (PERCENT_START_HEADER): ... this.
6481 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6482 (declaration): Update token names and m4 macro names.
6483 When parsing %end-header and %start-header, invoke translate_code
6484 before muscle_code_grow, and no longer set global booleans to remember
6485 whether these declarations have been seen.
6486 Parse new %after-header and %before-header.
6487 * src/reader.c (before_definitions, after_definitions): Remove.
6488 (prologue_augment): Accept a new bool argument to specify whether to
6489 augment the pre-prologue or post-prologue.
6490 * src/reader.h (before_definitions, after_definitions): Remove these
6492 (prologue_augment): Add new bool argument.
6493 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
6494 (PERCENT_END_HEADER): ... this.
6495 (PERCENT_BEFORE_DEFINITIONS): Update to...
6496 (PERCENT_START_HEADER): ... this.
6497 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
6498 * tests/actions.at (Printers and Destructors): Update names.
6500 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
6502 Add comparison operators for C++ location classes. Discussed at
6503 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
6504 * data/c++.m4 (b4_define_location_comparison): New boolean %define
6505 declaration indicating whether filename_type has an operator==. If
6506 filename_type is `std::string', it defaults to `1', `0' otherwise.
6507 * data/location.cc: Iff b4_define_location_comparison is `1', add
6508 operator== and operator!= for class position and for class location.
6511 * src/scan-action.l: Remove unused file.
6512 * src/symtab.c (symbol_printer_set): Use printer_location not
6513 destructor_location.
6514 * src/symtab.h (struct symbol): Replace incorrect source comment for

6519 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
6521 Don't put the pre-prologue in the header file. For the yacc.c code
6522 file and the glr.c header and code files, move the pre-prologue before
6523 the token definitions. Add new %before-definitions and
6524 %after-definitions to declare code that will go in both the header file
6525 and code file. Discussed at
6526 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
6527 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
6529 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
6530 * NEWS (2.3+): Describe these changes.
6531 * data/glr.c (b4_pre_prologue): Move from within to before...
6532 (b4_shared_declarations): ... this.
6533 Add new b4_before_definitions before b4_token_enums.
6534 Add new b4_after_definitions at the end.
6535 * data/glr.cc (b4_pre_prologue): Replace with...
6536 (b4_before_definitions): ... this in the header file.
6537 (b4_after_definitions): New near the end of the header file.
6538 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
6539 code file right before including the header file.
6540 (b4_before_definitions): New in the previous position of
6541 b4_pre_prologue in the header file.
6542 (b4_after_definitions): New near the end of the header file.
6543 * data/yacc.c: Clean up some m4 quoting especially in the header file.
6544 (b4_token_enums_defines): In the code file, move to right before
6545 YYSTYPE for consistency with the header file.
6546 (b4_before_definitions): New right before b4_token_enums_defines in
6547 both the header and code file.
6548 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
6549 header and code file.
6550 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
6551 of prologues for %union dependencies.
6552 (Decl Summary): In %defines description, mention the effect of
6553 %before-definitions and %after-definitions on the header file.
6554 (Calc++ Parser): Forward declare driver in a %before-definitions rather
6555 than in the pre-prologue so that make check succeeds.
6556 (Table of Symbols): Add entries for %before-definitions and
6558 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
6559 %before-definitions.
6560 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
6561 (declaration): Parse those declarations and append to
6562 b4_before_definitions and b4_after_definitions, respectively.
6563 * src/reader.c (before_definitions, after_definitions): New bools to
6564 track whether those declarations have been seen.
6565 (prologue_augment): Add to the post-prologue if %union,
6566 %before-definitions, or %after-definitions has been seen.
6567 * src/reader.h (before_definitions, after_definitions): New extern's.
6568 * src/scan-gram.l: Scan the new declarations.
6569 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
6570 prologue block in a %before-definitions or a %after-definitions based
6571 on whether the %union is declared.
6572 * tests/regression.at (Early token definitions with --yacc, Early token
6573 definitions without --yacc): Move tests for token definitions into the
6574 post-prologue since token names are no longer defined in the
6577 2006-06-20 Akim Demaille <akim@epita.fr>
6579 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
6580 (symbol_get): Use it.
6581 * src/parse-gram.y: Use it.
6583 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
6585 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
6586 build succeeds when configured with --enable-gcc-warnings.
6588 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
6590 * src/parse-gram.y (char_name): New function.
6591 (CHAR, STRING, string_content): For %printer, properly escape.
6592 (ID): Prefer fputs to fprintf.
6593 (id): Reindent to be consistent with other rules.
6594 Properly quote char.
6596 The Translation Project changed its way of publishing translations
6597 to maintainers. I haven't received any responses to my request
6598 for supporting the old way, or for documenting the new way. I
6599 have modified 'bootstrap' to use screen scraping
6600 (in this case, HTML scraping). This is unreliable and inelegant,
6601 but I don't see any better way. Yuck.
6602 * bootstrap (TP_URL, WGET_COMMAND): New vars.
6603 (get_translations): New function, which uses HTML scraping to
6604 deduce locations of latest translations.
6605 Use this function to grab both bison and bison-runtime .po files.
6606 Don't bother priming the pump for the runtime-po domain any more,
6607 as it's now translated better than bison is.
6609 2006-06-19 Akim Demaille <akim@epita.fr>
6611 * src/scan-gram.l: No longer "parse" things after `%union' until
6612 `{'. Rather, return a single "%union" token.
6613 No longer make symbols: return strings, and leave the conversion
6614 to symbols to the parser.
6615 (SC_PRE_CODE, token_type): Remove.
6616 * src/parse-gram.y (%union): New field `character'.
6619 (ID, ID_COLON): Now that the scanner no longer makes them
6620 identifiers, adjust all uses to invoke symbol_get.
6621 (id_colon): New, wraps the conversion from string to symbol.
6622 (%union): Accept a possible union_name.
6623 (symbol): Now can be a char.
6624 * data/c.m4 (b4_union_name): Leave a default value.
6625 * data/glr.c, data/yacc.c: Use it.
6627 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
6629 For associating token numbers with token names for "yacc.c", don't use
6630 #define statements unless `--yacc' is specified; always use enum
6631 yytokentype. Most important discussions start at:
6632 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
6633 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
6635 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
6636 * NEWS (2.3+): Mention.
6637 * data/c.m4 (b4_yacc_if): New.
6638 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
6640 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
6641 on token name definitions.
6642 * src/getargs.c (usage): Capitalize `Yacc' in English.
6643 * src/output.c (prepare): Define b4_yacc_flag.
6644 * tests/regression.at (Early token definitions): Test that tokens names
6645 are defined before the pre-prologue not just before the post-prologue.
6646 Remove this test case and copy to...
6647 (Early token definitions with --yacc): ... this to test #define's.
6648 (Early token definitions without --yacc): ... and this to test enums.
6650 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
6652 * NEWS: Reword the post-2.3 change to not be so optimistic about
6653 removing the old "look-ahead" spelling.
6654 Update previous look-ahead/lookahead change reports.
6655 * REFERENCES: look-ahead -> lookahead (since that's
6656 what he actually wrote).
6657 * doc/refcard.tex: look ahead -> lookahead,
6658 look-ahead -> lookahead
6660 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
6662 For consistency, use `lookahead' instead of `look-ahead' or
6663 `look_ahead'. Discussed starting at

6696 * src/print.c: Update English in comments.
6697 (lookahead_set): Rename from look_ahead_set.

6735 * src/flex-scanner.h (yytext): Remove stray `*/' in #define.
6737 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
6739 * TODO: Add request from Nelson H. F. Beebe to be able to install
6740 Bison without installing the yacc script.
6742 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
6744 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
6745 and yytext if they're already #define'd.
6746 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
6747 * src/scan-code-c.c: ... here.
6748 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
6751 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
6753 Get Bison to build again when configured with --enable-gcc-warnings.
6754 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
6756 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
6757 loc argument as it shadows a global.
6758 * src/scan-gram.l: Remove stray comma that prevents boundary_set
6761 * src/.cvsignore: Add scan-code.c.
6763 2006-06-07 Akim Demaille <akim@epita.fr>
6765 * src/scan-gram.l: Move the "add a trailing ; to actions" code
6767 * src/scan-code.l: here.
6768 * tests/input.at (Torturing the Scanner): Fix another location
6771 2006-06-07 Akim Demaille <akim@epita.fr>
6773 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
6775 2006-06-06 Akim Demaille <akim@epita.fr>
6777 Extract the parsing of user actions from the grammar scanner.
6778 As a consequence, the relation between the grammar scanner and
6779 parser is much simpler. We can also split "composite tokens" back
6781 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
6782 * src/scan-gram.l (add_column_width, adjust_location): Move to and
6784 * src/location.h, src/location.c (add_column_width)
6785 (location_compute): these.
6786 Fix the column count: the initial column is 0.
6787 (location_print): Be robust to ending column being 0.
6788 * src/location.h (boundary_set): New.
6789 * src/main.c: Adjust to scanner_free being renamed as
6791 * src/output.c: Include scan-code.h.
6792 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
6794 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
6795 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
6796 which is now, again, a separate token.
6797 Adjust all dependencies.
6798 Whereever actions with $ and @ are used, use translate_code.
6799 (action): Remove this nonterminal which is now useless.
6800 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
6801 (grammar_current_rule_action_append): Use translate_code.
6802 (packgram): Bound check ruleno, itemno, and rule_length.
6803 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
6804 (last_string, last_braced_code_loc, max_left_semantic_context)
6805 (scanner_initialize, scanner_free, scanner_last_string_free)
6806 (gram_out, gram_lineno, YY_DECL_): Move to...
6807 * src/scan-gram.h: this new file.
6808 (YY_DECL): Rename as...
6810 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
6811 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
6812 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
6813 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
6814 Move these declarations, and...
6815 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
6817 * src/flex-scanner.h: this new file.
6818 * src/scan-gram.l (rule_length, rule_length_overflow)
6819 (increment_rule_length): Remove.
6820 (last_braced_code_loc): Rename as...
6821 (gram_last_braced_code_loc): this.
6822 Adjust to the changes of the parser.
6823 Move all the handling of $ and @ into...
6824 * src/scan-code.l: here.
6825 * src/scan-gram.l (handle_dollar, handle_at): Remove.
6826 (handle_action_dollar, handle_action_at): Move to...
6827 * src/scan-code.l: here.

6838 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
6840 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
6841 Use Akim's wording from
6842 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
6844 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
6846 Between Bison releases, manually append `+' to the previous Bison
6847 release number, and use that as a signal to automatically print the
6848 ChangeLog's CVS Id keyword from --version. Discussed starting at
6849 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
6850 * ChangeLog: Add Id header.
6851 * configure.ac (AC_INIT): Append `+' to `2.3'.
6852 * src/.cvsignore: Add revision.c.
6853 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
6854 (BUILT_SOURCES): Add revision.c.
6855 (revision.c): New target rule. This file defines a new global variable
6856 named revision. It initializes it with either the Id from ChangeLog
6857 or, if VERSION doesn't contain `+', with the empty string.
6858 * src/getargs.c (version): Print the value of revision.
6859 * src/revision.h: Extern revision.
6861 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
6863 * NEWS: Version 2.3.
6864 * configure.ac (AC_INIT): Likewise.
6866 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
6868 * data/glr.c (YYRECOVERING): Define to be a function-like macro
6869 with no arguments, not as an object-like macro. This is for
6870 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
6871 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
6872 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
6875 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
6877 * src/getargs.c (usage): Back out yesterday's modification of the
6878 --help output so that we don't have to wait for translation before
6881 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
6883 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
6884 Problem reported by Akim Demaille.
6886 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
6888 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
6890 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
6892 * data/yacc.c (yy_reduce_print): Omit trailing white space in
6893 generated source code. Problem reported by Frans Englich in
6894 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
6896 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
6898 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
6899 shell, not within 'make', so that 'make' by an ordinary builder
6900 (using GNU make) does not worry about configuring gzip. This also
6901 works around a bug reported independently by Keith Thompson and by
6902 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
6903 stderr rather than stdout, messing up the build logs.
6905 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
6907 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
6908 to make sure that YYID will never be unused. This fixes a 'make
6909 maintainer-check' failure caused by the recent changes to the 'Trivial
6910 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
6912 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
6914 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
6916 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
6917 state before an empty RHS is always resolved here. Only the location
6918 of that state is guaranteed to be resolved, and that's enough. This
6919 fixes the remaining bug reported by Derek M. Jones in
6920 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6921 * tests/glr-regression.at (Uninitialized location when reporting
6922 ambiguity): Test the above case.
6923 Also, the embedded comments in this test case claim it checks the case
6924 of an empty RHS that has inherited the initial location. However, the
6925 corresponding LHS was already resolved, so yyresolveLocations didn't
6926 actually have reason to modify it. Fix this by forcing
6927 nondeterministic operation at the beginning of the parse.
6929 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6931 * data/c.m4 (b4_yy_symbol_print_generate):
6932 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
6933 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
6934 of the bugs reported today by Derek M Jones in
6935 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6936 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
6937 defined to be a type name without parens or brackets.
6938 (Location Type): Similarly for YYLTYPE.
6939 * tests/regression.at (Trivial grammars): Put in a test for this
6940 bug that will be caught by 'make maintainer-check' (though not,
6941 alas, by 'make check' unless your compiler is picky).
6943 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6945 * NEWS: Version 2.2.
6946 * configure.ac (AC_INIT): Likewise.
6948 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
6950 * data/glr.c (yyreportTree): Make room in yystates for the state
6951 preceding the RHS. This fixes the segmentation fault reported by Derek
6953 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
6954 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
6955 to the user. Reported for yyreportTree by Derek M. Jones later in the
6957 * THANKS: Add Derek M. Jones.
6958 Update my email address.
6959 Fix typo in Steve Murphy's name.
6961 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6963 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
6964 checking against YYLAST that caused the parser to miss a potential
6965 alternative in its diagnostic.
6966 Problem reported by Maria Jose Moron Fernandez in
6967 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
6968 * data/lalr1.cc (yysyntax_error_): Likewise.
6969 * data/yacc.c (yysyntax_error): Likewise.
6970 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
6971 tokens, in case we run into an older C compiler.
6972 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
6973 Use them to check for the off-by-one error fixed above.
6975 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
6976 YYSIZE_T, not size_t.
6977 * tests/regression.at (Trivial grammars): New test, to catch
6978 the error fixed by the above patch.
6980 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6982 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
6984 Reported by Steve Murphy.
6986 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6988 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
6989 * data/glr.cc: b4_location_flag is now b4_locations_flag.
6991 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6993 Implement --trace=m4.
6994 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
6995 * src/output.c (output_skeleton): When set, pass -dV to m4.
6997 Factor the handling of flags in m4.
6998 * src/output.c (prepare): Rename the muscle names debug, defines,
6999 error_verbose to debug_flag, defines_flag, error_verbose_flag.
7000 * data/c.m4: Adjust.
7001 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
7002 Use b4_define_flag_if to define other b4_FLAG_if macros.
7003 (b4_location_if): As a consequence, rename as...
7004 (b4_locations_if): this, for consistency.
7005 Adjust all the skeletons.
7007 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7009 * etc/bench.pm: Shorten bench names.
7011 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7013 * src/output.h, src/output.c (error_verbose): Move to...
7014 * src/getargs.h, src/getargs.c: here.
7016 Adjust dependencies.
7018 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
7020 * data/c.m4 (b4_copyright): Put the special exception for Bison
7021 skeletons here, so we don't have to put it in each skeleton. All
7022 uses changed. Suggested by Akim Demaille. Also, wrap the
7023 copyright notice, in case it is longer than 80 columns. Replace
7024 comma by newline after title.
7026 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
7028 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
7029 incompatibility, not a bug. Mention that it wasn't fixed as of
7032 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7034 * examples/extexi: Enforce the precedence of concatenation over
7036 Reported by Tommy Nordgren.
7038 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7040 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
7041 with the member "token".
7042 Reported by Martin Nylin.
7044 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
7046 * data/glr.c: Switch to Bison 2.2 special-exception language in
7047 the copyright notice. Use more-regular format for titles and
7049 * data/glr.cc: Likewise.
7050 * data/location.cc: Likewise.
7051 * data/yacc.cc: Likewise.
7052 * doc/bison.texinfo (Conditions): Document this.
7053 * NEWS: likewise. Upgrade version to 2.2.
7055 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
7057 * data/glr.cc: Remove dead code.
7059 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
7061 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
7062 that variable and the line breaks the bootstrap. Problem reported
7063 by Juan M. Guerrero.
7065 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
7067 * doc/bison.texinfo (Multiple start-symbols): New.
7069 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
7071 * etc/README, etc/bench.pl: New.
7073 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
7075 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
7077 Reported by Mickael Labau.
7078 * tests/input.at (Torturing the Scanner): Test it.
7080 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
7082 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
7083 Problem reported by Bob Rossi.
7085 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
7087 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
7088 and didn't really work.
7089 For the index, use @ifnotinfo, not @iftex.
7090 Minor cleanups of spacing and terminology.
7092 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
7094 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
7095 of AT_NAME_PREFIX when %name-prefix is not used.
7097 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
7099 Apply --prefix to C++ skeletons too: they change the namespace.
7100 The test suite already exercize these cases.
7101 * data/c++.m4 (b4_namespace): New.
7102 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
7103 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
7104 * data/yacc.c, data/glr.c: Remove a useless `[]'.
7105 * doc/bison.texinfo: Document it.
7106 (Option Cross Key): Use @multitable in all formats. It looks
7107 nicer, even in TeX outputs.
7108 (Rules): Use the same code whatever the output type is.
7109 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
7110 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
7111 * tests/calc.at: Use it, instead of hard coding `yy'.
7113 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
7115 * TODO: Remove dead items.
7117 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
7119 * doc/FAQ: Remove, merged into...
7120 * doc/bison.texinfo (FAQ): this.
7121 * doc/Makefile.am (EXTRA_DIST): Adjust.
7123 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
7125 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
7127 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
7128 * doc/bison.texinfo (Calc++ Scanner): Use it.
7130 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
7132 Fix two nits reported by twlevo, plus one more that I discovered.
7134 * src/assoc.h (assoc_to_string): Give a name to the arg, as
7135 this is the usual Bison style.
7136 * src/location.h (location_print): Likewise.
7138 * src/reader.h (token_name): Likewise.
7140 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
7142 Fix some nits reported by twlevo.
7143 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
7144 and "POSIX". Use more-modern syntax for URLs. Mention C++
7145 and ask for Java. Don't hardwire OS version numbers. Add
7147 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
7148 * src/conflicts.c (solved_conflicts_obstack): Now static.
7150 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
7152 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
7153 page. Say "you can use it" not "you may use it" as on the web page;
7154 we're describing capabilities not granting permission.
7156 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
7158 * data/glr.c (yyresolveLocations): Rename local variables to avoid
7159 shadowing warnings. Use usual patter for iterating through RHS.
7160 * tests/glr-regression.at
7161 (Uninitialized location when reporting ambiguity):
7162 Modify yylex so that it uses its argument, rather than trying
7163 to rely on ARGSUSED (which doesn't work for gcc with warnings).
7164 const char -> char const.
7166 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
7167 Don't use tabs inside commands; it messes up 'ps'.
7168 Problem reported by twlevo.
7170 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
7172 * tests/glr-regression.at (Uninitialized location when reporting
7173 ambiguity): New test case.
7174 * data/glr.c (yyresolveLocations): New function, which uses
7176 (yyresolveValue): Invoke yyresolveLocations before reporting an
7178 * doc/bison.texinfo (Default Action for Locations): Note
7179 YYLLOC_DEFAULT's usage for ambiguity locations.
7180 (GLR Semantic Actions): Cross-reference those notes.
7182 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
7184 * tests/glr-regression.at (Leaked semantic values when reporting
7185 ambiguity): Remove unnecessary union and type declarations.
7186 (Leaked lookahead after nondeterministic parse syntax error): New test
7188 * data/glr.c (yyparse): Check for zero stacks remaining before
7189 attempting to shift the lookahead so that you don't lose it.
7191 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
7193 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
7194 * tests/glr-regression.at (Leaked semantic values when reporting
7195 ambiguity): New test case.
7196 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
7197 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
7198 now unnecessary yystackp parameter.
7199 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
7200 destructors can be called.
7202 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
7203 in existing testcases.
7205 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
7207 Don't leak semantic values for parent RHS when a user action cuts the
7208 parser, and clean up related code a bit.
7209 * tests/glr-regression.at (Leaked merged semantic value if user action
7210 cuts parse): Rename to...
7211 (Leaked semantic values if user action cuts parse): ... this. Add check
7212 for leaked parent RHS values.
7213 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
7214 between an unresolved state (non-empty chain of semantic options) and
7215 an incomplete one (signaled by an empty chain).
7216 (yyresolveStates): Document the interface. Move all manipulation of a
7217 successfully or unsuccessfully resolved yyGLRState to...
7218 (yyresolveValue): ... here so that yyresolveValue always leaves a
7219 yyGLRState with consistent data and thus is easier to understand.
7220 Remove the yyvalp and yylocp parameters since they are always just
7221 taken from the yys parameter. When reporting a discarded merged value
7222 in debugging output, note that it is incompletely merged. Document the
7224 (yyresolveAction): If resolving any of the RHS states fails, destroy
7225 them all rather than leaking them. Thus, as long as user actions are
7226 written to clean up the RHS correctly, yyresolveAction always cleans up
7227 the RHS of a semantic option. Document the interface.
7229 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
7231 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
7232 led to a segmentation fault in GNU Pascal. Problem reported
7235 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
7237 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
7238 mid-rule action inside a nonterminal symbol in order to declare a
7239 destructor for its semantic value.
7241 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
7243 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
7244 YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
7245 __cplusplus && ! defined _STDLIB_H && !
7246 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
7247 defined free))]: Include <stdlib.h> rather than rolling our own
7248 declarations of malloc and free, to avoid problems with
7249 incompatible declarations (using 'throw') C++'s stdlib.h. This
7250 should fix Debian bug 340012

7256 * NEWS: Clarify symbols versus types in unused-value warnings.
7258 * configure.ac (AC_INIT): Bump version number.
7260 2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
7262 * NEWS: Version 2.1a.
7263 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
7264 since C99 requires this.
7266 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
7268 * m4/c-working.m4: New file.
7269 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
7271 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
7273 * Makefile.maint: Merge from coreutils.
7275 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
7277 More portability fixes for problems summarized by Nelson H. F. Beebe.
7279 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
7280 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
7281 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
7282 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
7283 messes up because C++ code is compiled in 32-bit mode but linked

7288 More portability fixes for problems summarized by Nelson H. F. Beebe.
7290 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
7291 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
7293 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
7294 nodist_PROGRAMS, since we don't need to actually compile the
7295 example if we're just doing a plain 'make'. This avoids bothering
7296 the installer unnecessarily about problems due to weird C++
7299 2006-02-06 Paul Eggert <eggert@cs.ucla.edu>
7301 More portability fixes for problems summarized by Nelson H. F. Beebe.
7303 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
7304 than #include "...", and compile with -I'.'. The old method was
7305 not portable, according to Posix and the C standard, and it does
7306 not work with Sun C 5.7, where previous #line directives affect
7307 the working directory used in later #include "..." directives.

7317 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check that
7318 '#include <map>' works and that you can apply ++ to iterators.
7320 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
7322 Work around portability problems summarized by Nelson H. F. Beebe in

7325 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
7326 that '#include <string>' works.
7328 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
7329 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
7330 "warning: sorry: semantics of inline function static data `const
7331 unsigned char translate_table[262]' are wrong (you'll wind up with
7334 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
7335 or, xor to not_, and_, or_, and xor_, respectively. This works
7336 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
7337 random system header somewhere that includes the equivalent of
7340 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
7341 -E" works; it apparently doesn't work with PathScale EKO Compiler
7344 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
7346 During deterministic GLR operation, user actions should be able to
7347 influence the parse by changing yychar. To make this easier to fix and
7348 to make glr.c easier to evolve in general, don't maintain yytoken in
7349 parallel with yychar; just compute yytoken when needed.
7350 * tests/glr-regression.at (Incorrect lookahead during deterministic
7351 GLR): Check that setting yychar in a user action has the intended
7353 * data/glr.c (yyGLRStack): Remove yytokenp member.
7354 (yyclearin): Don't set *yytokenp.
7355 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
7356 yychar rather than *yytokenp to determine the current lookahead.
7357 Compute yytoken locally when needed.
7358 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
7361 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
7362 after `--report' documentation.

7366 * src/parse-gram.y (grammar_declaration): Location of printer
7367 symbol is @1, not list->location. Bug reported by twlevo.

7370 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
7372 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
7373 all the test at once. This makes the output easier to read in the
7376 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
7377 got from <http://bro-ids.org/download.html>. The bug is that
7378 when two actions appeared in succession, the second one was
7379 scanned before the first one was added to the grammar rule
7380 as a midrule action. Bison then output the incorrect warning
7381 "parse.y:905.17-906.36: warning: unused value: $3".
7382 * src/parse-gram.y (BRACED_CODE, action): These are no longer
7383 associated with a value.
7384 (rhs): Don't invoke grammar_current_rule_action_append.
7385 (action): Invoke it here instead.
7386 * src/reader.c (grammar_midrule_action): Now extern.
7387 (grammar_current_rule_action_append): Don't invoke
7388 grammar_midrule_action; that is now the scanner's job.
7389 * src/reader.h (last_string, last_braced_code_loc):
7390 (grammar_midrule_action): New decls.
7391 * src/scan-gram.l (last_string): Now extern, sigh.
7392 (last_braced_code_loc): New extern variable.
7393 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
7394 rule already has an action.
7395 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
7396 * tests/input.at (AT_CHECK_UNUSED_VALUES):
7397 Add some tests to check that the above changes fixed the bug.
7399 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
7401 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
7402 All used changed. Check whether the symbol has a destructor,
7403 not whether it is typed.
7404 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
7405 that the values are still reported as unused. All line numbers

7419 Work around a bug in Pike 7.0, and give the Pike folks a
7420 better way to override the usual int widths.
7421 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
7422 user can override the types.
7423 (short): #undef, to work around a bug in Pike 7.0.
7424 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
7425 (union yyalloc.yyss): Use yytype_int16 rather than short.
7427 (yysigned_char): Remove.
7428 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
7429 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
7430 * tests/regression.at (Web2c Actions): Adjust to above changes.
7432 * src/reader.c (check_and_convert_grammar): New function.
7433 (reader): Close the input file even if something went wrong during
7434 parsing. Minor file descriptor leak reported by twlevo.
7436 * src/assoc.c (assoc_to_string): Use a default: abort (); case
7437 to pacify gcc -Wswitch-default.
7438 * src/scan-gram.l (adjust_location): Use a default: break; case
7439 to pacify gcc -Wswitch-default.

7643 in the yychar entry.
7644 In the yychar entry, remove mention of the local yychar case (pure
7645 parser) since this is irrelevant information when writing semantic
7646 actions and since it's already discussed in `Table of Symbols' where
7647 yychar is otherwise described as an external variable.
7648 In the yychar entry, don't call it the `current' look-ahead since it
7649 isn't when semantic actions are deferred.
7650 In the yychar and yyclearin entries, add note about deferred semantic
7652 Add yylloc and yylval entries discussing look-ahead usage.
7653 (Look-Ahead Tokens): When discussing yychar, don't call it the

7674 appropriately during nondeterministic operation.
7675 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
7676 members to store the current lookahead to be used by the deferred
7678 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
7679 from which the RHS is taken. Set the lookahead members of the new
7680 yySemanticOption according to the lookahead status for stack yyk.

7682 yyaddDeferredAction.
7683 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

7694 (Incorrect lookahead during nondeterministic GLR): New test case.
7696 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

7708 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
7710 * data/glr.c (yyresolveValue): When merging semantic options, if at
7711 least one user action succeeds but a later one cuts the parse, then
7712 destroy the semantic value before returning rather than leaking it.
7713 (yyresolveStates): If a user action cuts the parse and thus
7714 yyresolveValue fails, ignore the (unset) semantic value rather than
7715 corrupting the yyGLRState, and empty the semantic options list since
7716 the user actions should have called all necessary destructors.
7717 Simplify code with YYCHK.
7718 * tests/glr-regression.at (Corrupted semantic options if user action
7719 cuts parse): New test case.
7720 (Undesirable destructors if user action cuts parse): New test case.

7917 Undo 2005-12-01 tentative license wording change. The wording is
7918 still being reviewed by the lawyers, and we don't want to wait for
7919 them before publishing a test release. For now, revert to the

7941 * tests/cxx-type.at: Construct a tree, count the parents of shared
7942 nodes, and free each node once and only once. Previously, the memory
7943 for semantic values was leaked instead.
7945 2005-12-21 Joel E. Denny <address@hidden>
7947 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.

7967 destroy the RHS symbols of a rule.
7968 * data/yacc.c (yylen): Initialize to 0.

7987 * djgpp/config.sed: Replace every occurence of the file name
7988 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

8018 sed out the final state number.
8020 Work around portability problem on Solaris 10: flex-generated
8021 files include <stdio.h> before <config.h>, which messes up
8022 because the latter defines __EXTENSIONS__. Address the problem
8023 by creating two new little files that include <config.h> first,
8024 then include the flex-generated files. Rewrite everyone else
8025 to include <config.h> first, as well.
8026 * lib/timevar.c: Always include "config.h".

8072 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
8073 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
8074 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
8076 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
8077 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
8078 Use YYID(0) rather than 0, for lint.
8079 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.

8102 it's no longer just a file.
8103 * data/glr.c: Grant a special exception for C GLR parsers, that
8104 reads like the already-existing exception for C LALR(1) parsers.

8106 * data/lalr1.cc: Likewise.

8390 unused-variable warnings. This pacifies 'lint'.
8391 * data/lalr1.cc (yysymprint_, yydestruct_): Use a call to suppress
8392 unused-variable warnings.
8394 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>
8396 * Makefile.am: DJGPP specific files added to EXTRA_DIST.
8398 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
8400 Use unlocked I/O for a minor performance improvement on hosts like
8401 GNU/Linux and Solaris that support unlocked I/O. The basic idea
8402 is to use the gnlib unlocked-io module, and to prefer putc and
8403 puts to printf when either will work (since the latter doesn't
8404 come in an unlocked flavor).
8405 * bootstrap (gnulib_modules): Add unlocked-io.
8406 * data/c.m4 (yysymprint): Prefer puts and putc to printf.

8423 * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
8424 * src/system.h: Include unlocked-io.h rather than stdio.h.
8426 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
8427 this confuses xgettext.

8476 to allow support for non-posix systems. This is a no-op function
8479 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
8480 handle the lack of pipe/fork functionality on non-posix systems.
8482 * djgpp/Makefile.maint: DJGPP specific file.
8484 * djgpp/README.in: DJGPP specific file.
8486 * djgpp/config.bat: DJGPP specific configuration file.

8503 filename type is defined by the user.
8504 Forward declation location and position before the pre-prologue.

8514 Alexandre Duret-Lutz <adl@gnu.org>
8516 Move the token type and YYSTYPE in the parser class.
8517 * data/lalr1.cc (stack.hh, location.hh): Include earlier.
8518 (parser::token): New, from the moved free definition of tokens.
8519 (parser::semantic_value): Now a full definition instead of an
8520 indirection to YYSTYPE.
8521 (b4_post_prologue): No longer included in the header file, but
8522 in the implementation file.
8523 * doc/bison.texi (C+ Language Interface): Update.

8564 local variables whose names begin with 'yy'.
8565 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
8566 Trivial changes from Joel E. Denny.
8568 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
8570 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
8571 don't use alloca any more.
8573 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
8574 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
8575 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
8576 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
8577 to match yacc.c, to test more hosts.
8579 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
8581 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
8582 doesn't affect behavior.
8583 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
8585 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
8586 This works a bit better with glibc, if user code has already included
8588 * doc/bison.texinfo (Bison Parser): Document that users can't
8589 arbitrarily use malloc and free for other purposes. Document
8590 that <alloca.h> and <malloc.h> might be included.

8603 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
8604 (YYSTACK_ALLOC_MAXIMUM): Use it.
8605 (yysyntax_error): New function.
8606 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
8607 multiple syntax errors are reported, and alloca is being used.
8608 Instead, reallocate buffers twice as big each time, so that
8609 we waste at most half the allocated memory. Start with a small
8610 (128-byte) buffer that will suffice in most cases anyway.
8611 Use yysyntax_error to do most of the work.
8613 * doc/bison.texinfo (Error Reporting, Table of Symbols):
8614 yynerrs is the number of errors reported, not the number of
8617 * tests/glr-regression.at (Duplicated user destructor for lookahead):
8618 Mark it as expected to fail.
8619 Cast result of malloc; problem reported by twlevo@xs4all.nl.
8620 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
8621 Don't start user-code symbols with "yy", to avoid name space problems.
8623 2005-09-19 Akim Demaille <akim@epita.fr>
8625 Remove the traits, failed experiment.
8626 It never proved useful, and anyway because of the current
8627 definition, it was not possible to have several specialization of
8628 this traits, making it useless.
8629 * data/lalr1.cc (yy:traits): Remove.
8630 Inline its definitions in the parser class.
8632 2005-09-19 Akim Demaille <akim@epita.fr>

8654 * src/output.c (prepare): Likewise.
8655 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
8656 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
8657 is not defined. This is an awful hack, but it's enough for now.
8658 All callers changed.
8659 * tests/glr-regression-at (make_value): Args are const pointers now,
8660 to avoid GCC warning.
8661 (Duplicated user destructor for lookahead): New test. Currently
8662 skipped. It fails on my host but I'm not sure it'll always fail.
8664 2005-09-16 Akim Demaille <akim@epita.fr>
8666 * src/symtab.h (struct symbol): Declare the printer and destructor
8667 as const, to avoid accidental calls to free.
8668 (symbol_destructor_set, symbol_printer_set): Adjust.
8669 * src/symtab.c: Adjust.
8671 2005-09-16 Akim Demaille <akim@epita.fr>
8673 * data/c.m4 (b4_token_enums): New.
8674 (b4_token_defines): Rename as...
8675 (b4_token_enums_defines): this.
8676 (b4_token_defines): New, output only the #defines.
8677 * data/yacc.c, data/glr.c: Adjust.
8678 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
8679 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
8682 2005-09-16 Akim Demaille <akim@epita.fr>
8684 * data/lalr1.cc (yylex_): Remove, inline its code.
8685 (yyreport_syntax_error_): Remove, replaced by...
8686 (yysyntax_error_): this which returns a string and leaves to the
8687 caller the call to the users' error function.
8688 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
8689 Move from members of the parser object...
8690 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
8691 to local variables of the parse function.
8693 2005-09-16 Akim Demaille <akim@epita.fr>
8695 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
8696 since it's in Bison's name space.
8698 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
8700 * data/glr.c (yyresolveValue): Add default case to pacify
8701 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
8703 * NEWS: Document when yyparse started to return 2.
8704 * doc/bison.texinfo (Parser Function): Document when yyparse
8707 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
8708 (b4_filename_type): Renamed back from b4_file_name_type. All uses
8710 (class position): file_name -> filename (reverting). All uses changed.
8712 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
8714 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
8715 do anything if $@ exists. This reverts part of the 2005-07-07
8718 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
8720 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
8721 contains obsolete information and isn't worth distributing as a
8722 separate file anyway.
8723 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
8724 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
8725 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
8726 (yyparse): Abort if user code uses longjmp to throw an unexpected
8729 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
8731 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
8732 Suggested by twlevo@xs4all.nl.
8734 * data/glr.c (YYCHK1): Do not assume YYE is in range.
8735 This avoids a diagnostic from gcc -Wswitch-enum.
8736 Problem reported by twlevo@xs4all.nl.
8738 * doc/bison.texinfo: Don't use "filename", as per GNU coding
8739 standards. Use "file name" or "file" or "name", depending on
8741 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
8742 not to hack/foo.tab.c.
8743 (Calc++ Top Level): 2nd arg of main is not const.
8744 * data/glr.c: b4_filename -> b4_file_name.
8745 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

8764 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
8767 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
8769 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
8770 All uses changed. Invoke user destructor after an error during a
8771 split parse (trivial change from Joel E. Denny).
8773 * tests/glr-regression.at
8774 (User destructor after an error during a split parse): New test case.
8775 Problem reported by Joel E. Denny in:
8776 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
8778 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>

8785 variants. Use it instead of '-C off'. Problem reported by
8788 * data/glr.c (yydestroyStackItem): New function.
8789 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
8790 debugging information. Problem reported by Joel E. Denny.
8792 2005-08-25 Akim Demaille <akim@epita.fr>
8794 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
8796 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>

8800 * tests/glr-regression.at
8801 (User destructor for unresolved GLR semantic value): New test case.
8802 Problem reported by Joel E. Denny in:
8803 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
8805 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
8807 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
8809 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
8810 lib-prefix.m4, po.m4.
8812 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
8813 in yydestruct diagnostic, since it might not be an error.
8814 Problem reported by Joel Denny near end of
8815 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
8816 * data/lalr1.cc (yyerturn): Likewise.
8817 * data/yacc.c (yyreturn): Likewise.
8818 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
8820 * src/files.c: Remove obsolete FIXME comment.
8822 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
8823 with the other templates, and to fix bogus run-on messages such
8824 as the one reported at the end of
8825 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
8826 All callers changed to avoid the newline.
8827 (yyprocessOneStack): Output two lines rather than one, to accommodate
8828 the above change. This changes the debug output format slightly.
8830 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
8831 reported by Joel E. Denny in
8832 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
8834 * tests/glr-regression.at (Duplicate representation of merged trees):
8835 New test, from Joel E. Denny in:
8836 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
8837 * THANKS: Add Joel E. Denny.
8839 * configure.ac (AC_INIT): Bump to 2.0c.
8841 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
8843 * NEWS: Version 2.0b.
8845 * Makefile.am (SUBDIRS): Put examples before tests, so that
8846 "make check" doesn't finish with "All 1 tests passed".
8848 * tests/regression.at (Token definitions): Don't rely on
8849 AT_PARSER_CHECK for data that contains backslashes. It currently
8850 uses 'echo', and 'echo' isn't portable if its argument contains
8851 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
8852 that the byte '\0xff' is not printable in the C locale; it is,
8853 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
8854 not printable, so use '\0x81' to test.
8856 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
8857 version of GCC, since the macro is used with non-GCC compilers.
8859 Fix core dump reported by Pablo De Napoli in
8860 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
8861 * tests/regression.at (Invalid inputs with {}): New test.
8862 * src/parse-gram.y (token_name): Translate type before using
8865 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
8866 the user's name space. All uses changed to __attribute__
8868 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
8869 Add __attribute__ ((__noreturn__)).
8871 * etc/clcommit: Remove. We weren't using it, and it failed
8872 "make maintainer-distcheck".
8873 * Makefile.maint: Merge from coreutils.
8874 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
8875 (syntax-check-rules): Change list of rules as described below.
8876 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

8886 Use grep -n, to make it easier to find violations.
8887 Use CVS_LIST and CVS_LIST_EXCEPT.
8888 (header_regexp, h_re): Remove.
8890 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
8891 (my-distcheck): Use more-modern GCC flags.
8892 (signatures, %.asc): Remove.
8893 (rel-files, announcement): Remove signatures.
8894 Restore old updating code, even though we don't use it, so
8895 that we're the same as coreutils.
8896 (alpha, beta, major): Depend on news-date-check.
8897 Make the upload commands.
8899 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
8900 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
8901 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
8902 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
8903 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
8904 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
8905 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
8906 * tests/sets.at: Likewise.
8908 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
8909 we comment out the Autoconf version number.
8910 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
8911 it's error-prone and "make maintainer-distcheck" rejects it.
8913 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
8914 Indent calls to "error" to pacify "make maintainer-distcheck",
8915 when the calls are not intended to be translated.
8916 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
8918 * src/Makefile.am (DEFS): Use +=, to pacify
8919 "make maintainer-distcheck".
8920 (bison_SOURCES): Add scan-skel.h.
8921 (sc_tight_scope): New rule, from coreutils.
8923 * src/files.c (src_extension, header_extension):
8924 Now static, not extern.
8925 * src/getargs.c (short_options): Likewise.
8926 * src/muscle_tab.c (muscle_table): Likewise.
8927 * src/parse-gram.y (current_class, current_type, current_prec):
8929 * src/reader.c (grammar_end, previous_rule_end): Likewise.
8930 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
8931 * src/main.c (main): Cast bindtextdomain and textdomain calls to
8932 void, to avoid warning when NLS is disabled.
8933 * src/output.c: Include scan-skel.h.
8934 (scan_skel): Remove decl, since scan-skel.h does this.
8936 Indent calls to "error" to pacify "make maintainer-distcheck".
8937 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
8938 * src/reader.h (gram_end, gram_lineno): New decls to pacify
8939 "make maintainer-distcheck".
8940 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
8941 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
8942 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
8943 (skel_lex_destroy, scan_skel): Move these decls to...
8944 * src/scan-skel.h: New file.
8945 * src/uniqstr.c (uniqstr_assert):
8946 Indent calls to "error" to pacify "make maintainer-distcheck".
8948 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
8951 * tests/torture.at: Revamp to avoid misuse of atoi that
8952 "make maintainer-distcheck" complained about.
8954 * examples/extexi (message): Don't print a message more than once,
8955 and omit line-number decoration that makes Emacs compile think
8956 that informative messages are worth worrying about.
8958 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
8960 * configure.ac: Update version number.
8962 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
8964 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
8965 autogenerated by the maintainer.
8966 * examples/calc++/.cvsignore: Add *.yy.
8968 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
8969 * lib/bitset_stats.c (bitset_stats_init): Likewise.
8970 * lib/bitsetv.c (bitsetv_alloc): Likewise.
8972 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
8974 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
8975 from maintainer-distcheck about casting the argument of 'free'.
8977 * NEWS: Mention recent yytname changes.
8978 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
8980 * bootstrap: For translations that have not yet been upgraded to
8981 the new runtime-po domain, prime the pump by extracting the
8982 relevant strings from the obsolete translations. This code can be
8983 removed once the bison-runtime domain has been translated by each
8986 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
8987 now that token names are already quoted.
8989 Fix problem reported by Anthony Heading.
8990 * data/glr.c (YYTOKEN_TABLE): New macro.
8991 (yytname): Define if YYTOKEN_TABLE.
8992 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
8993 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
8994 (YYERROR_VERBOSE): Define the same way the other skeletons do.
8995 * src/output.c (prepare_symbols): Output token_table_flag.
8997 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
8999 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
9000 again if the first call fails.
9002 * data/glr.c (yytnamerr): New function.
9003 (yyreportSyntaxError): Use it to dequote most string literals.
9004 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
9005 with other skeletons. All uses changed.
9006 (yytnameerr_): New function.
9007 (yyreport_syntax_error): Use it to dequote most string literals.
9008 * data/yacc.c (yytnamerr): New function.
9009 (yyerrlab): Use it to decode most string literals.
9010 * doc/bison.texinfo (Decl Summary, Calling Convention):
9011 Clarify quoting convention of yytname.
9012 * src/output.c (prepare_symbols): Quote all names. This undoes
9013 the 2005-04-17 change, which is now accomplished (mostly) via
9014 changes in the parsers as described above.
9015 * tests/regression.at (Token definitions, Web2c Actions):
9016 Undo most 2005-04-17 change here, too.
9018 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
9020 Fix more problems reported by twlevo@xs4all.nl.
9021 * tests/cxx-type.at: Don't pipe output of ./types through sed to
9022 remove trailing spaces. This loses the exit status of ./types,
9023 and isn't needed since ./types shouldn't be emitting trailing
9025 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
9026 as the stack isn't valid in that case.
9028 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
9029 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
9030 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
9031 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
9033 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
9034 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
9035 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
9038 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
9039 overly-picky compilers that reject 'char *foo = "bar";'.
9041 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
9042 to FILE * parameter, not to stderr. This fixes a typo introduced
9043 in the 2005-07-12 change.
9045 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
9046 warnings from GCC 4.
9048 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
9049 (yyglrShiftDefer, yysplitStack):
9050 Remove unused parameters b4_pure_formals. All uses changed.
9051 (yyglrShift): Remove unused parameters b4_user_formals.
9053 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
9055 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
9057 Destructor cleanups and regularization among the three skeletons.
9058 * NEWS: Document the behavior changes.
9059 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
9060 stack before failing, as the cleanup code will do it for us now.
9061 * data/lalr1.cc (yyerrlab): Likewise.
9062 * data/glr.c (yyparse): Pop everything off the stack before
9063 freeing it, so that destructors get called properly.
9064 * data/lalr1.cc (yyreturn): Likewise.
9065 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
9066 This is more consistent.
9067 * doc/bison.texinfo (Destructor Decl): Mention more reasons
9068 why destructors might be called. 1.875 -> 2.1.
9069 (Destructor Decl, Decl Summary, Table of Symbols):
9070 Some English-language cleanups for %destructor.
9071 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9072 Add output line for destructor of start symbol.
9073 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
9074 because of that same extra output line.
9076 * NEWS: Document minor wording changes in diagnostics of
9077 Bison-generated parsers.
9078 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
9079 Remove unused formals. All uses changed.
9080 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
9081 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
9082 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
9083 Rename yyoverflowab to yyexhaustedlab.
9084 When memory exhaustion occurs during syntax-error reporting,
9085 report it separately rather than in a single diagnostic; this
9087 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
9088 (Memory Exhausted): Renamed from Parser Stack Overflow.
9089 Revamp wording slightly to prefer "memory exhaustion".
9090 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
9092 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
9094 Add i18n support to the GLR skeleton. Partially fix the C++
9095 skeleton; a C++ expert needs to finish this. Remove debugging
9096 msgids; there's little point to having them translated, since they
9097 can be understood only by someone who can read the
9098 (English-language) source code.
9100 Generate runtime-po/bison-runtime.pot automatically, so that we
9101 don't have to worry about garbage getting in that file. We'll
9102 make sure after the next official release that old msgids don't
9104 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
9106 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
9108 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
9109 Fix typos in explanations of the runtime file.
9110 * bootstrap: Change gettext keyword from YYI18N to YY_.
9111 Use standard Makefile.in.in in runtime-po, since we'll arrange
9112 for backward-compatible bison-runtime.po files in a different way.
9113 * data/glr.c (YY_): New macro, from yacc.c.
9114 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
9115 Translate messages intended for users.
9116 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
9117 the wording in the other skeletons. We don't know that the memory
9119 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
9120 Use same method that yacc.c uses.
9121 Don't translate debugging messages.
9122 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
9123 it doesn't work (yet), and requires C++ expertise to fix.
9124 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
9125 Move defn to a more logical place, to be consistent with other
9127 Don't translate debugging messages.
9128 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
9129 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
9130 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
9131 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
9133 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
9134 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
9136 * tests/glr-regression.at (Badly Collapsed GLR States):
9138 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
9139 yylex should return 0 at EOF rather than aborting.
9141 Improve tests for stack overflow in GLR parser.
9142 Problem reported by twlevo@xs4all.nl.
9143 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
9145 (yyStackOverflow): Just longjmp, but with value 2 so that caller
9146 can handle the problem.
9147 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
9148 (yyparse): New local variable yyresult to record the result.
9149 Use result of setjmp to set it, rather than storing itinto
9151 (yyDone): Remove label.
9152 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
9153 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
9154 if YYABORT is used).
9155 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
9156 yyparse status; put status > 1 into diagnostic.
9157 Check that status==2 works.
9158 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
9159 Use exit status 3 for failure to open (which shouldn't happen).
9161 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
9163 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
9164 1 on syntax error; just let yyparse do its thing.
9165 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
9166 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
9167 (Exploding the Stack Size with Alloca):
9168 (Exploding the Stack Size with Malloc):
9169 Expect exit status 2, not 1, since the parser is supposed to blow
9170 its stack. Problem reported by twlevo@xs4all.nl.
9172 * data/glr.c (yyparse): Don't assume that the initial calls
9173 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
9174 Print a stack-overflow message and fail instead.
9175 Initialize the line-number information before creating the stack,
9176 so that the stack-overflow message can report line zero safely.
9178 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
9180 Fix problems reported by twlevo@xs4all.nl.
9181 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
9182 (yyuserMerge): Provide a default case if b4_mergers is empty.
9183 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
9184 * tests/glr-regression.at
9185 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
9186 Add casts to pacify C++ compilers.
9187 * tests/glr-regression.at (Improper merging of GLR delayed action
9188 sets): Declare yylex before using it.
9189 * tests/Makefile.am (maintainer-check-g++): Fix a stray
9190 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
9191 test for valgrind; valgrind is independent of g++.
9192 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
9193 for compatibility with POSIX 1003.1-2001 (if running coreutils).
9194 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
9195 Use a destructor, so that we can expand the stack. Change
9196 YYSTYPE to char * so that we can free it. Cast result of malloc.
9198 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9200 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
9201 a valgrind failure. Problem reported by twlevo@xs4all.nl.
9203 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
9205 * PACKAGING: New file, suggested by Bruno Haible and taken from
9206 similar wording in gettext's PACKAGING file.

9212 * NEWS: Document recent i18n improvements.
9213 * bootstrap: Get runtime translations into runtime-po.
9214 Create runtime-po files automatically, if possible.
9215 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
9216 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
9217 does not infringe on the user's name space.
9218 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
9219 * doc/bison.texinfo (Internationalization): Revamp the English
9220 and Texinfo syntax a bit, to try to make it clearer.
9221 (Bison Options, Option Cross Key): Mention --print-localedir.
9222 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
9223 YYENABLE_NLS. Quote a bit more.

9233 * runtime-po/Makevars: Likewise.
9234 * runtime-po/LINGUAS: Likewise.
9235 * runtime-po/de.po: Likewise; we will rely on the translation project
9236 to maintain this, so "bootstrap" should get it.
9237 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
9239 * src/main.c (main): Bind the bison-runtime domain, too.
9241 2005-07-12 Bruno Haible <bruno@clisp.org>
9243 * data/yacc.c: Include <libintl.h> when NLS is enabled.
9244 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
9245 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
9246 * runtime-po: New directory.
9247 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
9248 $(DOMAIN).pot-update rule, so that old messages are never dropped.
9249 * runtime-po/Rules-quot: New file, copied from po/.
9250 * runtime-po/quot.sed: Likewise.
9251 * runtime-po/boldquot.sed: Likewise.

9267 (PRINT_LOCALEDIR_OPTION): New enum item.
9268 (long_options): Add --print-localedir option.
9269 (getargs): Handle --print-localedir option.

9271 (Internationalization): New section.
9273 2005-07-12 Akim Demaille <akim@epita.fr>
9275 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,

9288 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
9290 2005-07-12 Akim Demaille <akim@epita.fr>
9292 * data/glr.c (b4_syncline): Fix (swap) the definitions of
9293 b4_at_dollar and b4_dollar_dollar.
9295 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
9297 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
9298 and Pennello's paper.
9300 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
9302 * data/yacc.c (yyparse): Undo previous patch. Instead,
9303 set yylsp[0] and yyvsp[0] only if the initial action
9304 sets yylloc and yylval, respectively.
9306 * data/yacc.c (yyparse): In the initial action, set
9307 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
9308 This avoids the use of undefined variables if the initial
9309 action does not set yylloc and/or yylval.
9311 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
9313 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
9314 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
9315 Remove from CVS. These files are automatically generated.
9316 * examples/extexi: Clarify that this file is now part of Bison,
9317 not GNU M4, and that it works with any POSIX-compatible Awk.
9318 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
9319 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
9320 so that we also get calc++-parser.yy. Geneate it.
9321 Use $(AWK), not gawk, since any conforming Awk will do.
9322 Put comment before action, since older 'make' can't handle comment
9324 $(BUILT_SOURCES): List all built sources, not just some of them.
9325 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
9326 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
9327 $($(calc_sources_generated)): Remove unnecessary test for existence
9328 of target. (This had a shell syntax error anyway; a stray "x".)
9329 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
9331 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
9333 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
9334 implied by the other modules.
9336 2005-07-06 Akim Demaille <akim@epita.fr>
9338 Bind examples/calc++ to the package.
9339 * examples/calc++/Makefile: Remove, replaced by...
9340 * examples/calc++/Makefile.am: ... this new file.
9341 * examples/calc++/test: Remove input.
9342 * examples/calc++/compile: Remove.
9343 * examples/Makefile.am: New.
9344 * configure.ac, Makefile.am: Adjust.
9345 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
9347 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
9349 * data/glr.c (yyFail): Drastically simplify; since the format argument
9350 never had any % directives, we can simply pass it to yyerror.
9351 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
9352 be modified later, as that is the usual style in glr.c.
9353 Problems reported by Paul Hilfinger.
9355 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
9356 and size overflow errors.
9357 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
9358 in case the user prolog sets feature-test macros like _GNU_SOURCE.
9359 (YYSIZEMAX): New macro.
9360 (yystpcpy): New function, taken from yacc.c.
9361 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
9362 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
9363 so that we don't have to maintain their signatures.
9364 (yyFail): Check for buffer overflow, by using vsnprintf rather
9365 than vsprintf. Allocate a bigger buffer if possible.
9366 Report an error if buffer allocation fails.
9367 (yyStackOverflow): New function.
9368 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
9369 the initialization was successful. It might fail if storage was
9371 (yyexpandGLRStack): Add more checks for storage allocation failure.
9372 Use yyStackOverflow to report failures.
9373 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
9374 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
9375 Don't assume stack number fits in int.
9376 (yysplitStack): Check for storage allocation failure.
9377 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
9378 can print diagnostics on storage allocation failure. All callers
9380 (yyresolveValue): Use yybool for boolean.
9381 (yyreportSyntaxError): Check for size-calculation overflow.
9382 This code is taken from yacc.c.
9383 (yyparse): Check for storage allocation errors when allocating
9386 2005-07-05 Akim Demaille <akim@epita.fr>
9388 Extract calc++ from the documentation.
9389 * doc/bison.texinfo (Calc++): Add the extraction marks.
9390 * examples/extexi: New, from the aborted GNU Programming 2E.
9391 Separate the different paragraph of a file with empty lines.
9392 * examples/Makefile: Use it to extract the whole calc++ example.
9394 2005-06-24 Akim Demaille <akim@epita.fr>
9396 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
9399 2005-06-22 Akim Demaille <akim@epita.fr>
9401 * doc/bison.texinfo (C++ Language Interface): First stab.
9402 (C++ Parsers): Remove.
9404 2005-06-22 Akim Demaille <akim@epita.fr>
9406 * data/lalr1.cc (yylex_): Honor %lex-param.
9408 2005-06-22 Akim Demaille <akim@epita.fr>
9410 Start a set of simple examples.
9411 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
9412 * examples/calc++/calc++-driver.hh,
9413 * examples/calc++/calc++-parser.yy,
9414 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
9415 * examples/calc++/compile, examples/calc++/test: New.
9417 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
9419 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
9420 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
9421 which stems from the 2005-05-27 patch.
9423 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
9425 * data/glr.c: Modify treatment of unused parameters to permit use
9426 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
9428 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
9430 Fix infringement on user name space reported by Janos Zoltan Szabo.
9431 * data/yacc.c (yyparse): strlen -> yystrlen.
9433 2005-05-30 Akim Demaille <akim@epita.fr>
9435 * data/lalr1.cc (_): New.
9436 Translate the various messages.
9438 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
9440 Fix infringement on user name space reported by Bruno Haible.
9441 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
9442 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
9443 the user's name space.
9444 (alloca): Include <stdlib.h> to get it, if it's not built in.
9445 (YYMALLOC, YYFREE): Define only if needed.
9446 (malloc, free): Declare, but only if needed, as this infringes on
9447 the user name space.
9449 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
9451 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
9452 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
9454 * lib/ebitset.c (min, max): Undef before defining.
9455 * lib/vbitset.c (min, max): Likewise.
9456 * lib/subpipe.c (create_subpipe): Save local variables in case
9457 vfork clobbers them.
9459 2005-05-24 Bruno Haible <bruno@clisp.org>
9461 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
9462 error message syntax used by gcc-4.0.
9464 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
9466 * README: Mention m4 1.4.3. Remove obsolete advice about
9467 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
9469 * bootstrap: Remove workaround for problem I encountered with
9470 gettext 0.14.1; it seems to be fixed now.
9472 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
9474 * NEWS: Version 2.0a.
9476 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
9477 the previous change.
9479 Various maintainer cleanups.
9480 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
9481 conftest*, for benefit of CVS commands run at the same time as
9482 "configure". Add build-aux, since "bootstrap" now creates it and
9484 * Makefile.cfg (move_if_change): Remove.
9485 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
9486 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
9487 (po_repo, do-po-update, po-update, wget_files, get-targets):
9488 (config.guess-url_prefix, config.sub-url_prefix):
9489 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):

9491 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
9493 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
9494 this is now the recommended name.
9495 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
9496 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
9497 ylwrap. These files now go into build-aux.
9498 * config/move-if-change: Remove.
9499 * config/prev-version.txt: Bump from 1.75 to 2.0.
9501 * bootstrap: Add stdio-safer, unistd-safer modules.
9502 Remove m4/glibc2.m4 (introduced by latest gnulib, but
9504 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
9505 fopen-safer.c, stdio-safer.h, unistd-safer.h.
9506 * lib/subpipe.c: Include "unistd-safer.h".
9507 (create_subpipe): Make sure all the newly-created
9508 file descriptors are > 2, so that diagnostics don't
9509 get sent down them (which might cause Bison to hang, in theory).
9510 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
9511 * src/files.c (xfopen): Use fopen_safer, not fopen.
9513 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
9514 yesterday's yacc.c fix.
9516 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
9518 * data/glr.c, data/lalr1.cc: Update copyright date.
9520 Fix a destructor bug reported by Wolfgang Spraul in
9521 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
9522 * data/yacc.c (yyabortlab): Don't call destructor, and
9523 don't set yychar to EMPTY.
9524 (yyoverflowlab): Don't call destructor.
9525 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
9526 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
9527 since we no longer output the message "discarding lookahead token
9530 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9532 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
9533 fix a small glitch in debugging output.
9534 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
9535 after YY_SYMBOL_PRINT where needed.
9537 (struct yyGLRState): Add some comments.
9538 (struct yySemanticOption): Add some comments.
9539 (union yyGLRStackItem): Add comment.
9541 (yymergeOptionSets): Correct this to properly perform the union,
9542 avoiding infinite reported by Michael Rosien.

9586 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
9588 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
9589 Problem reported by Ralf Menzel.
9591 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
9593 * tests/actions.at: Test that stack overflow invokes destructors.
9594 From Marcus Holland-Moritz.
9595 * data/yacc.c (yyerrlab): Move the code that destroys the stack
9597 (yyreturn): to here. That way, destructors are called properly
9598 even if the stack overflows, or the user calls YYACCEPT or
9599 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
9600 (yyoverflowlab): Destroy the lookahead.
9602 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
9604 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
9606 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
9608 * NEWS: Bison-generated C parsers no longer quote literal strings
9609 associated with tokens.
9610 * src/output.c (prepare_symbols): Don't escape strings,
9611 since users don't want to see C escapes.
9612 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
9614 * tests/input.at (Torturing the Scanner): Likewise.
9615 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
9617 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
9619 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
9620 the data size is known to be too small and we can't increase it.
9621 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
9623 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
9625 * src/parse-gram.y: Include quotearg.h.
9626 (string_as_id): Quote $1 before using it as a key, since the
9627 lexer no longer quotes it for us.
9628 (string_content): Don't strip quotes, since lexer no longer
9630 * src/scan-gram.l: Include quotearg.h.
9632 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
9633 a key, since the rest of the lexer doesn't quote it.
9634 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
9635 * tests/regression.at (Token definitions): Check for backslashes
9638 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
9639 (YYSIZE_T): Define to unsigned long int when using an older compiler.
9640 (yyparse): Revamp code to generate long syntax error message, to
9641 make it easier to translate, and to avoid problems with arithmetic
9642 overflow. Change "virtual memory" to "memory" in diagnostic, since
9643 we don't know whether the memory is virtual.
9645 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
9647 * NEWS: Bison-generated C parsers now use the _ macro to
9649 * data/yacc.c (_) [!defined _]: New macro.
9650 All English strings wrapped inside this macro.
9651 * doc/bison.texinfo (Bison Parser): Document _.
9652 * po/POTFILES.in: Include src/parse-gram.c, since it now
9653 includes translateable strings that parse-gram.y doesn't.
9655 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
9657 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
9658 reverting the 2004-10-11 change to this function.
9659 (symbol_check_alias_consistency): Don't call symbol_type_set
9660 if the type name is already correct.
9661 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
9663 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
9665 * tests/regression.at (Token definitions): Don't use a token named
9666 c, as that generates a "#define c ..." that runs afoul of buggy
9667 stdlib.h that uses the identifier c as a member of struct
9668 drand48_data. Problem reported by Horst Wente.
9670 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
9672 * bootstrap: Change translation URL from
9673 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
9674 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
9675 redirection glitches. Problem reported by twlevo@xs4all.nl.
9677 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
9679 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
9680 after operands; POSIX says this isn't portable for the c99 command.
9682 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
9684 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
9685 immediately if a data overrun has occurred; this may help us track
9686 down what may be a spurious failure on MacOS.
9688 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
9690 Respond to problems reported by twlevo@xs4all.nl.
9692 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
9694 * src/vcg.h: Comment fix.
9695 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
9696 (G_CMAX): Change to -1 instead of INT_MAX.
9698 * data/yacc.c (yyparse): Omit spaces before #line.
9700 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
9702 * src/tables.c (state_number_to_vector_number): Put it inside an
9703 "#if 0", since it's not currently used. Problem reported by
9706 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
9708 * src/output.c (escaped_output): Renamed from
9709 escaped_file_name_output, since we now use it for symbol tags as
9710 well. All uses changed.
9711 (symbol_destructors_output, symbol_printers_output):
9712 Escape symbol tags too.
9713 Problem reported by Matyas Forstner in
9714 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
9716 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
9718 * src/output.c (user_actions_output, token_definitions_output,
9719 symbol_destructors_output, symbol_printers_output): Likewise.
9720 * src/reader.c (prologue_augment): Likewise.
9721 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
9723 * src/vcg.c (output_edge): Don't quote linestyle arg.
9724 Problem reported by twlevo@xs4all.nl.
9726 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
9728 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
9729 example, reported by Derek M Jones. Also, make the example even
9730 more outrageous, to better illustrate how bad the problem is.
9732 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
9734 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
9735 putsym. Typo reported by Sebastian Piping.
9737 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
9739 * doc/bison.texinfo (Language and Grammar): some -> same
9740 (Epilogue): int he -> in the
9741 Typos reported by Sebastian Piping via Justin Pence.
9743 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
9745 * tests/glr-regression.at (Improper handling of embedded actions
9746 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
9747 embedded actions and $-N in GLR parsers", work around an Autoconf bug
9748 with dollar signs in test names.
9749 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
9750 for a similar reason.
9752 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9754 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
9755 wants to redefine G_VIEW.
9757 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
9759 * src/vcg.c (get_view_str): Remove case for normal_view.
9760 Problem reported by twlevo@xs4all.nl.
9762 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
9764 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
9765 Problem reported by twlevo@xs4all.nl.
9767 * doc/bison.texinfo: Change @dircategory from "GNU programming
9768 tools" to "Software development". Requested by Richard Stallman
9771 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
9773 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
9774 Problem reported by twlevo@xs4all.nl.
9776 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
9778 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
9779 keyword; it's not needed with modern compilers, and it doesn't
9780 affect correctness with older compilers. Suggested by
9783 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
9785 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
9786 gcc -Wswitch-default.
9787 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
9788 * data/yacc.c (yyparse): Likewise.
9790 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
9792 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
9793 already. Let config.h define any nonstandard values.
9795 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
9797 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
9798 for the benefit of slower hosts. Problem reported by
9801 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
9803 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
9804 being defined and not used.
9805 * data/lalr1.cc (yyparse): Likewise.
9806 Use "if (false)" rather than "if (0)".
9808 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
9810 * TODO: Mention that we should allow NUL bytes in tokens.
9812 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
9814 * src/scan-skel.l (<<EOF>>): Don't close standard output.
9815 Problem reported by Hans Aberg.
9817 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
9819 * src/getargs.c (version): Happy new year; update overall
9820 program copyright date from 2004 to 2005.
9822 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
9823 Problem reported by Hans Aberg.
9824 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
9825 (Output file names.): Add a test for the case when standard output
9828 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
9830 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
9831 to fix an oversight in the Bison 2.0 manual.
9833 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
9835 * NEWS: Version 2.0. Reformat the existing news items since
9836 1.875, so that related items are grouped together.
9837 * configure.ac (AC_INIT): Bump version to 2.0.
9838 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
9840 * tests/torture.at (Exploding the Stack Size with Alloca): Set
9841 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
9842 otherwise, we're not testing alloca. Unfortunately there's no
9843 simple way to consult HAVE_ALLOCA here.
9845 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
9848 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
9849 hand. This avoids a warning about comparing int to size_t when
9850 GCC warnings are enabled.
9852 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
9854 * NEWS: Bison-generated parsers no longer default to using the
9855 alloca function (when available) to extend the parser stack, due
9856 to widespread problems in unchecked stack-overflow detection.
9857 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
9858 responsibility to set it to a positive value. This lets the user
9859 specify a value that is not a preprocessor constant.
9860 * data/yacc.c (YYMAXDEPTH): Likewise.
9861 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
9862 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
9863 to be a compile-time constant. However, explain the constraints on it.
9864 Also, explain the constraints on YYINITDEPTH.
9865 (Table of Symbols): Explain that alloca is no longer the default.
9866 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
9869 * doc/bison.texinfo (Location Default Action): Mention that n must
9870 be zero when k is zero. Suggested by Frank Heckenbach.
9872 2004-12-22 Akim Demaille <akim@epita.fr>
9874 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
9875 (parser::state_type, parser::semantic_type, parser::location_type):
9876 Private, not public.
9877 (parser::parse): Return ints, not bool.
9878 Returning a bool introduces a problem: 0 corresponds to false, and
9879 it seems weird to return false on success. Returning true changes
9880 the conventions for yyparse.
9881 Alternatively we could return void and send an exception.
9882 There is no clear consensus (yet?).
9883 (state_stack, semantic_stack, location_stack): Rename as...
9884 (state_stack_type, semantic_stack_type, location_stack_type): these.
9885 Private, not public.
9886 * tests/c++.at: New.
9887 * tests/testsuite.at, tests/Makefile.am: Adjust.
9889 2004-12-21 Akim Demaille <akim@epita.fr>
9891 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
9893 2004-12-21 Akim Demaille <akim@epita.fr>
9895 Don't impose std::string for filenames.
9897 * data/lalr1.cc (b4_filename_type): New.
9898 (position::filename): Use it.
9899 (parser.hh): Move the inclusion of stack.hh and location.hh below
9900 the user code, so that needed headers for the filename type can be
9902 Forward declare them before the user code.
9903 * tests/Makefile.am (check-local, installcheck-local): Pass
9904 TESTSUITEFLAGS to the TESTSUITE.
9906 2004-12-20 Akim Demaille <akim@epita.fr>
9908 Use more STL like names: my_class instead of MyClass.
9910 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
9911 (SemanticStack, SemanticType, StateStack, StateType)
9912 (TokenNumberType, Stack, Slice, Traits, Parser::location)
9913 (Parser::value): Rename as...
9914 (location_stack, location_type, rhs_number_type, semantic_stack)
9915 (semantic_type, state_stack, state_type, token_number_type, stack)
9916 (slice, traits, parser::yylloc, parser::yylval): these.
9918 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
9920 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
9922 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
9923 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
9925 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
9927 Remove uses of 'short int' and 'unsigned short int'. This raises
9928 some arbitrary limits. It uses more memory but nowadays that's
9929 not much of an issue.
9931 This change does not affect the generated parsers; that's a different
9932 task, as some users will want to conserve memory there.
9934 Ideally we should use size_t to represent all object counts, and
9935 something like ptrdiff_t to represent signed differences of object
9936 counts; but that will require more code-cleanup than I have the
9937 time to do right now.
9939 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
9940 Use size_t, not int or short int, to count objects.
9941 * src/closure.c (nritemset, closure): Likewise.
9942 * src/closure.h (nritemset, closure): Likewise.
9943 * src/nullable.c (nullable_compute): Likewise.
9944 * src/print.c (print_core): Likewise.
9945 * src/print_graph.c (print_core): Likewise.
9946 * src/state.c (state_compare, state_hash): Likewise.
9947 * src/state.h (struct state): Likewise.
9948 * src/tables.c (default_goto, goto_actions): Likewise.
9950 * src/gram.h (rule_number, rule): Use int, not short int.
9951 * src/output.c (prepare_rules): Likewise.
9952 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
9953 errs, reductions): Likewise.
9954 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
9956 * src/tables.c (vector_number, tally, action_number,
9957 ACTION_NUMBER_MINIMUM): Likewise.
9958 * src/output.c (muscle_insert_short_int_table): Remove.
9960 2004-12-17 Akim Demaille <akim@epita.fr>
9962 * data/lalr1.cc: Extensive Doxygenation.
9963 (error_): Rename as...
9964 (error): this, since it is visible to the user.
9966 (Parser::message): Now an automatic variable from...
9967 (Parser::yyreport_syntax_error_): here.
9968 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
9970 * tests/input.at: Escape $.
9972 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
9974 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
9975 Parenthesize rhs to avoid obscure problems with mistakes like
9976 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
9977 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
9978 b4_rhs_location): Likewise.
9979 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
9980 b4_rhs_location): Likewise.
9982 2004-12-16 Akim Demaille <akim@epita.fr>
9984 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
9985 yacc.c: be sure to stay within yycheck_.
9986 * tests/actions.at: Re-enable C++ tests.
9988 2004-12-16 Akim Demaille <akim@epita.fr>
9990 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
9993 2004-12-16 Akim Demaille <akim@epita.fr>
9995 Use #define to handle the %name-prefix.
9997 * data/glr.c, data/yacc.c: Comment changes.
9998 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
9999 so that one can refer to yylex in the parser file, and have it
10000 renamed, as is the case with other skeletons.
10002 2004-12-16 Akim Demaille <akim@epita.fr>
10004 Move lalr1.cc internals into yy*.

10024 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
10026 Fix some problems reported by twlevo at xs4all.
10027 * src/symtab.c (symbol_new): Report an error if the input grammar
10028 contains too many symbols. This is better than calling abort() later.
10029 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
10030 (struct node, struct graph):
10031 Rename member expand to stretch. All uses changed.
10032 (struct graph): Remove member layoutalgorithm. All uses removed.
10033 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
10034 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
10036 (N_STRETCH): Rename from N_EXPAND. All uses changed.
10038 2004-12-15 Akim Demaille <akim@epita.fr>
10040 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
10041 Add more Doxygen comments.
10042 (symprint_, stack_print_, reduce_print_, destruct_, pop)
10043 (report_syntax_error_, translate_): Rename as...
10044 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
10045 (yypop_, yyreport_syntax_error_, yytranslate_): this.
10047 2004-12-15 Akim Demaille <akim@epita.fr>
10049 * data/lalr1.cc (lex_): Rename as...
10051 Move the trace here.
10052 Take the %name-prefix into account.
10053 Reported by Alexandre Duret-Lutz.
10055 2004-12-15 Akim Demaille <akim@epita.fr>
10057 Simplify the C++ parser constructor.
10059 * data/lalr1.cc (debug_): Rename as...
10060 (yydebug_): so that the parser's internals are always in the yy*
10063 (b4_parse_param_decl): Remove the leading comma as it is now only
10064 called as unique argument list.
10065 (Parser::Parser): Remove the constructor accepting a location and
10066 an initial debugging level.
10067 Remove from the other ctor the argument for the debugging level.
10068 (debug_level_type, debug_level, set_debug_level): New.
10070 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
10073 2004-12-15 Akim Demaille <akim@epita.fr>
10075 Remove b4_root related material: failure experiment
10076 (which goal was to allow to derive from a class).
10078 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
10079 definitions and uses.
10081 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
10083 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
10084 not 2, since it's not portable to subtract 1 from the start of an
10085 array. The new item 0 is never set or used. All uses changed.
10087 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
10088 the default definition of YYLLOC_DEFAULT. Problem reported
10089 by Frank Heckenbach.
10091 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
10093 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
10094 the normal case and one for the error case. Just use the
10095 first one uniformly. Problem reported by Frank Heckenbach.
10096 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
10097 use exactly the same macro in both places.
10098 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
10099 so that the normal-case YYRHSLOC works for the error case too.
10101 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
10102 (YYLLOC_DEFAULT): Use the same macro as glr.c.
10103 * doc/bison.texinfo (Location Default Action): Don't claim that
10104 we have an array of locations. Use the same macro for both glr
10105 and lalr parsers. Mention YYRHSLOC. Mention what happens when
10108 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
10110 * HACKING: Update email addresses to send announcements to.
10112 * configure.ac (AC_INIT): Bump version to 1.875f.
10114 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>

10117 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
10119 * src/scan-skel.l: Include "complain.h", for "fatal".
10121 * src/relation.h (relation_print, relation_digraph):
10122 Relation sizes are of type relation_node, not size_t (this is
10123 merely a doc fix, since the two types are equivalent).
10124 (relation_transpose): Relation sizes are of type relation_node,
10126 * src/relation.c: Likewise.
10127 (top, infinity): Now of type relation_node, not int.
10128 (traverse, relation_transpose): Use relation_node, not int.
10130 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
10131 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
10132 (yyparse): Remove unused local introduced in 2004-10-25 patch.
10134 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
10135 specifying whether the test should be skipped. Use it tp
10136 specify that the [%defines %skeleton "lalr1.cc"] tests currently
10137 fail on some hosts, and should be skipped.
10139 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
10141 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
10142 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
10143 unless otherwise specified below.
10145 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
10146 to allocate kernel_base, kernel_items, kernel_size, since
10147 they needn't be initialized to 0.
10148 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
10149 * src/closure.c (new_closure): Likewise, for itemset.
10150 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
10151 * src/lalr.c (set_goto_map): Likewise, for temp_map.

10158 (relation_transpose): Likewise for new_R, end_R.
10159 * src/symtab.c (symbols_token_translations_init): Likewise for
10160 token_translations.
10161 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
10162 (token_actions): Likewise for yydefact, actrow, conflrow,

10165 (goto_actions): Likewise for state_count.
10166 (pack_table): Likewise for base, pos, check.
10167 (tables_generate): Likewise for width.
10169 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
10170 for initial core. Just have a separate core, so we needn't worry
10171 about whether kernel_size and kernel_base are initialized.
10173 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
10174 kernel_size, kernel_items): Remove unnecessary initialization.
10175 * src/conflicts.c (conflicts): Likewise.
10176 * src/derives.c (derives): Likewise.
10177 * src/muscle_tablc (muscle_insert): Likewise.

10179 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
10180 conflrow, conflict_table, conflict_list, table, check):
10183 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
10184 This is because all callers pass unsigned int.
10185 * src/closure.h (new_closure): Likewise.
10187 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
10188 (build_relations): Initialize includes[i] in all cases.
10189 * src/reader.c (packgram): Always initialize rules[ruleno].prec
10190 and rules[ruleno].precsym. Initialize members in order.
10191 * src/relation.c (relation_transpose): Always initialize new_R[i]
10193 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
10195 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
10196 conflict_list[0] was always 0, but now it isn't initialized.
10198 * src/table.c (table_grow): When conflict_table grew, the grown
10199 area wasn't cleared. Fix this.
10201 * lib/.cvsignore: Add strdup.c, strdup.h.
10202 * m4/.cvsignore: Add strdup.m4.

10206 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
10207 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
10208 GOTO_NUMBER_MAXIMUM, since we occasionally compute
10209 ngotos + 1 without checking for overflow.
10210 (build_relations): Use END_NODE, not -1, to denote end of edges.
10211 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
10212 build_relations): Use goto_number, not int, for goto numbers.
10213 * src/tables.c (save_column, default_goto): Likewise.
10215 2004-11-23 Akim Demaille <akim@epita.fr>
10217 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
10218 of #defining from yystype.
10219 Don't typedef yystype, C++ does not need it.
10220 This lets it possible to forward declare it as union.
10222 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
10224 * bootstrap (gnulib_modules): Add extensions.
10225 Problem reported by Jim Meyering.
10227 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
10229 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
10230 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
10231 src/system.h, src/tables.c: XFREE -> free, to accommodate
10232 recent change to gnulib xalloc.h.
10233 Problem reported by Jim Meyering.
10235 2004-11-17 Akim Demaille <akim@epita.fr>
10237 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
10239 2004-11-17 Akim Demaille <akim@epita.fr>,
10240 Alexandre Duret-Lutz <adl@gnu.org>
10242 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
10244 (YYCDEBUG): Adjust.
10245 Use it instead of cdebug_.
10246 (Parser::debug_stream, Parser::set_debug_stream): New.
10247 (Parser::symprint_): Define cdebug_ for temporary backward
10249 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
10252 2004-11-17 Akim Demaille <akim@epita.fr>
10254 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
10255 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
10256 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
10257 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
10259 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
10261 * data/glr.c (yyloc_default): Remove; not used.
10262 Problem reported by Frank Heckenbach.
10264 2004-10-25 Akim Demaille <akim@epita.fr>
10266 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
10267 Introduce another definition to address simple location arrays.
10268 (yyGLRStack): New member: yyerror_range.
10269 (yyrecoverSyntaxError, yyparse): Update it.
10270 (yyrecoverSyntaxError): Use it when shifting the error token to
10271 have an accurate range, equivalent to the one computed by both
10272 yacc.c and lalr1.cc.
10273 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
10274 that column numbers start at column 0, as per GNU Coding
10275 Standards, the others tests, and the doc.
10276 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
10277 Adjust to the above change (first column is 0).
10278 And adjust the location of the "<error>", now covering the whole
10281 2004-10-22 Akim Demaille <akim@epita.fr>
10282 and Paul Eggert <eggert@cs.ucla.edu>
10284 Remove some arbitrary limits on goto numbers and relations.
10285 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
10286 initial values, since they're never used.
10287 (set_goto_map): ngotos is now unsigned, so test for overflow
10288 by seeing whether it wraps around to zero.
10289 * src/lalr.h (goto_number): Now size_t, not short int.
10290 (GOTO_NUMBER_MAXIMUM): Remove.
10291 * src/relation.c (relation_print, traverse, relation_transpose):
10292 Check for END_NODE rather than looking at sign.
10293 * src/relation.h (END_NODE): New macro.
10294 (relation_node): Now size_t, not short int.
10296 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
10298 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
10299 keyword, not an identifier. Problem reported by Baron Schwartz in
10300 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
10302 2004-10-11 Akim Demaille <akim@epita.fr>
10304 * src/symtab.c (symbol_check_alias_consistency): Also check
10305 type names, destructors, and printers.
10306 Reported by Alexandre Duret-Lutz.
10307 Recode the handling of associativity and precedence in terms
10308 of symbol_precedence_set.
10309 Accept no redeclaration at all, not even equal to the previous
10311 (redeclaration): New.
10312 Use it to factor redeclaration complaints.
10313 (symbol_make_alias): Don't set the type of the alias, let
10314 symbol_check_alias_consistency do it as for other features.
10315 * src/symtab.h (symbol): Add new member prec_location, and
10317 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
10318 * tests/input.at (Incompatible Aliases): New.
10320 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
10322 .cvsignore fixes to accommodate gnulib changes,
10323 and the practice of naming build directories "_build".
10324 * .cvsignore: Add "_*". Sort.
10325 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
10326 * m4/.cvsignore: Add "*_gl.m4".
10328 2004-10-06 Akim Demaille <akim@epita.fr>
10330 * src/parse-gram.y (add_param): Fix the truncation of trailing
10333 2004-10-05 Akim Demaille <akim@epita.fr>
10335 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
10336 whether the reducion was empty or not. This leaves room to
10337 improve the use of YYLLOC_DEFAULT in such a case.
10338 lalr1.cc is still experimental, so changing this is acceptable.
10339 And finally, there are probably not many users who changed the
10340 handling of locations in GLR, so changing is admissible too.
10342 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
10343 empty reduction, set @$ to an empty location ending the previously
10345 Adjust uses to make sure the code is triggered on empty
10347 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
10348 expected output: empty reductions have empty locations.
10350 2004-09-29 Akim Demaille <akim@epita.fr>
10352 * data/lalr1.cc: Move towards a more standard C++ coding style
10353 for templates: Class < T > -> Class<T>.
10355 2004-09-29 Akim Demaille <akim@epita.fr>
10357 * data/lalr1.cc: Reinstall the former ctor, for sake of
10358 compatibility, but warn it will be removed.
10359 Move towards a more standard C++ coding style (i.e., type *var ->
10362 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
10364 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
10365 since it's less likely to work if NULs are involved in the future.
10367 2004-09-27 Akim Demaille <akim@epita.fr>
10369 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
10371 2004-09-27 Akim Demaille <akim@epita.fr>
10373 * data/lalr1.cc (b4_parse_param_decl_1): New.
10374 (b4_parse_param_decl): Use it to have different names between attribute
10375 and argument names.
10376 (b4_cc_constructor_call): Likewise.
10378 2004-09-24 Akim Demaille <akim@epita.fr>
10380 * src/parse-gram.y (add_param): Strip the leading and trailing
10381 blanks from a formal argument declaration.
10382 (YY_LOCATION_PRINT): New.
10384 2004-09-24 Akim Demaille <akim@epita.fr>
10386 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
10387 after the location.
10389 2004-09-24 Akim Demaille <akim@epita.fr>
10391 * doc/bison.texinfo (Table of Symbols): Sort.
10393 2004-09-21 Akim Demaille <akim@epita.fr>
10395 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
10396 the useless parentheses.
10397 Suggested by Paul Eggert.
10399 2004-09-20 Akim Demaille <akim@epita.fr>
10401 Let the initial-action act on the look-ahead, and use it for the
10402 "initial push" (corresponding to an hypothetical beginning-of-file).
10403 And let lalr1.cc honor %initial-action.
10405 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
10407 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
10408 (Parser::Parser): Remove the ctor that used to initialize it.
10409 (Parser::parse): Like in the other skeletons, issue the "starting
10410 parse" message before any action.
10411 Honor %initial-action.
10412 Initialize the stacks with the lookahead.
10413 * data/yacc.c: Let $$ and @$ in %initial-action designate the
10415 Push them in the stacks.
10416 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
10418 2004-09-20 Akim Demaille <akim@epita.fr>
10420 * doc/bison.texinfo (Initial Action Decl): New.
10422 2004-09-20 Akim Demaille <akim@epita.fr>
10424 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
10425 clearer criterion to define it.
10426 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
10427 When reducing on an empty RHS, use the latest stacked location as
10429 yylloc is not always available.
10430 * data/glr.c: Likewise.
10431 Also, honor initial-actions.
10433 2004-09-20 Akim Demaille <akim@epita.fr>
10435 * data/yacc.c (YY_LOCATION_PRINT): New.
10436 Define when we know YYLTYPE's structure, i.e., when the default
10437 YYLLOC_DEFAULT is used.
10438 * data/c.m4 (b4_yysymprint_generate): Use it.
10439 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
10440 value of the result.
10441 (error_start_): Replace with...
10442 (error_range_): this location array.
10443 This allows to replace code relying on the implementation of
10444 locations by portable code.
10445 * data/yacc.c (yylerrsp): Replace with...
10446 (yyerror_range): this.
10447 Every time a token is popped, update yyerror_range[0], to have an
10448 accurate location for the error token.
10449 * data/glr.c (YY_LOCATION_PRINT): New.
10450 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
10451 deference a pointer.
10452 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
10453 report the location in %printers.
10455 * src/scan-skel.l: Instead of abort, report error messages to ease
10456 understanding skeleton scanning failures.
10458 2004-09-16 Akim Demaille <akim@epita.fr>
10460 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
10461 (iterator, const_iterator): these, to be more in the C++ spirit.
10462 Also, return reverse iterators so that when displaying the stack
10463 we display its bottom first.
10464 (Parser::stack_print_, Parser::reduce_print_): Match the messages
10466 We should probably use vector here though.
10468 2004-09-16 Akim Demaille <akim@epita.fr>
10470 Have more complete shift traces.
10472 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
10473 to report Shifts instead of ad hoc YYDPRINTF invocations,
10474 including for the error token.
10475 * data/lalr1.cc (symprint_): Output the location.
10476 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
10477 output the location within the %printer.
10478 Activate GLR tests, at least to make sure they compile properly.
10479 They still don't pass though.
10480 * tests/calc.at: Adjust expect verbose output, since now "Entering
10481 state..." is on a different line than the "Shifting" message.
10483 2004-09-08 Akim Demaille <akim@epita.fr>
10485 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
10486 Bison directive from the Bison file to the invocation of this
10487 macro, so that these directives are passed to
10488 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10489 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10490 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10491 the extra Bison directives instead of the whole series.
10492 Change the grammar so that there are recoverable errors, and
10493 unrecoverable errors. Now we can have the parser give up before
10494 consuming the whole input. As a result we now can observe that
10495 the lookahead is freed when needed.
10496 Change the parser source to parse argv[1] instead of a hard coded
10498 Simplify yylex, and give a value and location to EOF.
10499 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10500 passed directives already coded in the file.
10501 Add some tests to check the location of "error".
10502 For some tests, the C++ parser is correct, and not yacc.c.
10503 For other tests, they provide different, but unsatisfying, values,
10504 so keep the C++ value so that at least one parser is "correct"
10505 according to the test suite.
10506 (Actions after errors): Remove, this is subsumed by the
10507 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
10509 2004-09-06 Akim Demaille <akim@epita.fr>
10511 * data/lalr1.cc: Adjust the indentation of the labels.
10512 (Parser::pop): New.
10515 2004-09-06 Akim Demaille <akim@epita.fr>
10517 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
10518 argument, an informative message.
10519 Call YY_SYMBOL_PRINT.
10520 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
10521 * data/lalr1.cc (destruct_): Likewise.
10522 In addition, no longer depend on b4_yysymprint_generate and
10523 b4_yydestruct_generate to generate these functions, do it "by
10526 2004-09-03 Akim Demaille <akim@epita.fr>
10528 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
10529 invoked, yydestruct the lookahead.
10530 * tests/calc.at (Calculator $1): Update the expected lengths of
10531 traces: there is an added line for the discarded lookahead.
10532 * doc/bison.texinfo (Destructor Decl): Some rewording.
10533 Define "discarded" symbols.
10535 2004-09-02 Akim Demaille <akim@epita.fr>
10537 * data/lalr1.cc (translate_, destruct_): No reason to be static.
10539 2004-09-02 Akim Demaille <akim@epita.fr>
10541 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
10542 (YYDSYMPRINTF): Rename as...
10543 (YY_SYMBOL_PRINT): this.
10544 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
10546 Use it instead of direct symprint_ calls.
10547 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
10550 2004-09-02 Akim Demaille <akim@epita.fr>
10552 * data/lalr1.cc (b4_yysymprint_generate): New.
10553 (symprint_): New member function, defined when YYDEBUG.
10554 Use it consistently instead of token/nterm debugging output by
10556 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
10557 %printer calls to use cdebug_ when using lalr1.cc.
10559 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
10561 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
10562 with #ifdef YYDEBUG.
10564 2004-08-26 Akim Demaille <akim@epita.fr>
10566 * doc/bison.texinfo (Implementing Loops): Rename as...
10567 (Implementing Gotos/Loops): this.
10569 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
10571 Adjust to latest gnulib.
10572 * bootstrap (gnulib_modules): Add xalloc-die.
10573 Set LC_ALL=C so that file names sort consistently.
10574 Prefer the gnulib copies of gettext.m4, glibc21.m4,
10575 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
10576 uintmax_t.m4, ulonglong.m4.
10577 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
10578 po.m4 since we are now using _gl.m4 instead.
10580 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
10582 * src/scan-action.l: Remove. Scanning of semantic actions is
10583 handled in scan-gram.l.
10585 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
10587 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
10589 * src/location.h (struct): The file member is a uniqstr.
10590 (equal_boundaries): Use UNIQSTR_EQ for comparison.
10592 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
10594 Fix bug with non-%union parsers that have printers or destructors,
10595 which led to a Bison core dump. Reported by Peter Fales in
10596 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
10598 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
10599 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
10600 not to our own type.
10601 * src/output.c (symbol_destructors_output, symbol_printers_output):
10602 Don't assume %union.
10603 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
10604 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
10605 UNION-FLAG. All callers changed.
10606 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
10607 Use type char, not unsigned int, when declaring an array of char;
10608 this lets us remove a cast.
10609 (Printers and Destructors): Add non-%union test cases.
10611 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10613 * doc/bison.texinfo: Minor editorial changes, mostly to the new
10614 GLR writeups. E.g., avoid frenchspacing and the future tense,
10615 change "lookahead" to "look-ahead", and change "wrt" to "with
10618 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10620 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
10621 New sections, split off from the GLR Parsers section. Put the new
10622 Simple GLR Parser near the start of the GLR section, for clarity.
10623 Rewrite connective text.
10625 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
10627 * doc/bison.texinfo (Simple GLR Parsers): New section.
10629 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10631 * NEWS, TODO, doc/bison.texinfo:
10632 Use "look-ahead" instead of "lookahead", to be consistent.
10633 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
10634 while we're fixing "look-ahead".
10635 * src/conflicts.c (shift_set): Renamed from shiftset.
10636 (look_ahead_set): Renamed from lookaheadset.
10637 * src/print.c: Likewise.
10638 * src/getargs.c (report_args): Add "look-ahead" as the new canonical
10639 name for "lookahead".

10643 * src/lalr.c (compute_look_ahead_tokens): Renamed from
10644 compute_lookaheads.
10645 (state_look_ahead_tokens_count): Renamed from state_lookaheads_count.
10646 (look_ahead_tokens_print): Renamed from lookaheads_print.
10647 * src/state.c (state_rule_look_ahead_tokens_print): Renamed from
10648 state_rule_lookaheads_print.
10649 * src/state.h: Likewise.
10650 (reductions.look_ahead_tokens): Renamed from lookaheads.
10651 * tests/torture.at (AT_DATA_LOOK_AHEAD_TOKENS_GRAMMAR): Renamed from
10652 AT_DATA_LOOKAHEADS_GRAMMAR.
10654 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
10656 * README: Update location of patched M4 distribution.
10658 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
10660 Don't assume the C++ compiler takes the same arguments as the C compiler
10662 * configure.ac (O0CXXFLAGS): New var.
10663 * tests/atlocal.in (CXXFLAGS): Use it.
10665 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>

10668 Albert Chin-A-Young for Tru64 C++ in this thread:
10669 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
10671 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
10672 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10673 Output to a .cc file for C++, not to a .c file.
10674 * tests/calc.at (AT_CHECK_CALC): Likewise.
10675 * tests/regression.at (AT_CHECK_DANCER): Likewise.
10676 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
10678 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
10680 * tests/calc.at, tests/actions.at: Workaround for SGI
10681 C++ compiler. (trivial change)
10683 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
10685 Spent a few hours checking out which prerequisite versions the
10686 current sources actually require. I went all the way back to
10687 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
10688 a seemingly endless set of combinations of versions more recent
10689 than that. The bottom line is that the current sources require
10690 fairly recent versions of the build tools, and it'll be some work
10692 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
10693 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
10694 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
10695 Add comments explaining why those particular versions are
10698 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
10699 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
10700 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
10702 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
10703 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
10705 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
10707 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
10708 0.11.5. Suggested by Bruno Haible.
10709 * bootstrap: Remove gettext version checking.
10711 * doc/bison.texinfo (Decl Summary): Also mention that %union
10712 can depend on prerequisite types. Problem reported by Tim
10715 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
10717 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
10718 * README-alpha: Don't tell people not to package this.
10720 * bootstrap: Don't assume $(...) works; use `...` instead.
10721 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
10724 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
10725 put into the -d output file, and mention what to do if YYSTYPE is
10726 defined as a macro.
10728 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
10730 Undo change made earlier today: it caused autopoint to not bring
10731 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
10734 * bootstrap: Check that gettext version matches what's in
10735 configure.ac. Warn users to ignore robots.txt ERROR 404.
10736 * bootstrap: Undo today's earlier change (logged below).
10737 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
10739 The gettext version checking is causing more trouble than it's
10740 curing; remove it. Problem reported by Paul Hilfinger.
10742 * bootstrap: Issue a warning that one can expect a message
10743 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
10744 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
10746 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
10748 Ensure that the C++ compiler used for testing actually works on a
10749 simple test program; if not, skip the C++-related tests. Problem
10750 reported by Vin Shelton in:
10751 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html

10758 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
10760 * data/glr.c (yylloc): Output this macro even if locations are not
10761 being generated, as the GLR parser needs it even in that case.
10762 Problem reported by Troy A. Johnson
10763 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
10765 * configure.ac (AC_INIT): Update to 1.875e.
10767 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
10769 * NEWS: Version 1.875d.
10770 * configure.ac (AC_INIT): Likewise.
10771 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
10773 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
10774 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
10775 lalr1.cc runs afoul of the first, and the last two are no longer
10776 supported by GCC 3.4.0.
10777 * README: Mention GNU m4 1.4 or later; mention m4 patches.
10778 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
10780 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
10782 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not

10794 character and string literals.
10795 (unexpected_end): New function.
10796 (unexpected_eof): Use it.
10797 (unexpected_newline): New function.
10798 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate

10804 Fix typo by replacing $1 with $option.
10805 Remove more 'intl'-related files.
10806 Don't DEFUN AM_INTL_SUBDIR twice.

10815 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
10816 * src/.cvsignore: Add *.output.
10818 * src/parse-gram.y: Put copyright notice inside %{ %} so it
10819 gets copied to the output file.
10821 2004-04-28 Paul Eggert <eggert@twinsun.com>
10823 Get files from the gnulib and po repositories, instead of relying
10824 on them being in our CVS. Upgrade to latest versions of gnulib
10827 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
10828 * bootstrap: Bootstrap from gnulib and po repositories.
10829 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
10830 * README-cvs: Document these changes. Remove version numbers from
10831 mentions of build tools, since they change so often. Mention Flex.
10833 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
10834 (gl_USE_SYSTEM_EXTENSIONS): Add.
10835 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
10836 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
10838 (AC_ISC_POSIX): Remove; we no longer support this
10839 ancient OS, as it gets in the way of latest Autoconf & gnulib.
10840 (AC_HEADER_STDC): Remove: we now assume C89 or better.
10841 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
10842 Do not check for C89 headers, except for locale.h which is used
10843 by the Yacc library and must port to K&R hosts.
10844 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
10845 Do not check for C89 functions, except for setlocale which is
10846 used by the Yacc library.
10847 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
10848 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

10851 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
10852 AM_GNU_GETTEXT): Remove; now done by:
10853 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
10854 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
10857 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
10858 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
10859 Define to empty, as gnulib.mk will do the rest for us.
10860 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
10862 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
10863 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
10865 * src/files.c: Include gnulib's xstrndup.h.
10867 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
10868 (REALLOC): Use xnrealloc, for likewise.
10869 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
10870 (strnlen, memrchr): Remove decls; functions no longer used.
10871 Include <stpcpy.h>.
10873 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

10893 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
10894 Remove, as these files are now generated automatically
10895 by bootstrap or automake.
10897 * po/ChangeLog: Remove: all but one entry was a duplicate
10898 of this file, and I moved that 2000-11-02 entry here.
10900 * config/.cvsignore: Add Makefile, depcomp, install-sh.
10901 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

10916 * po/.cvsignore: Add *.po, LINGUAS, Makefile.in.in, Makevars.
10917 * src/.cvsignore: Remove *_.c.
10920 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
10921 support it. (The latest stable gzip doesn't.)
10923 2004-04-27 Paul Eggert <eggert@twinsun.com>
10925 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
10926 case, as stos_ is now used by destructors due to the 2004-02-09
10929 Remove more K&R C support.
10930 * lib/libiberty.y (PARAMS): Remove. All uses removed.

10941 unconditionally. Do not declare perror.
10942 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
10945 * src/complain.c (_): Remove useless defn, as system.h defines this.
10947 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
10948 with latest obstack.h.
10949 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
10950 to procedure types, as obstack.h now does that for us.
10951 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
10953 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
10954 so that this include file can stand alone.
10955 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
10956 does this now. Include subpipe.h first after config.h, to
10957 test whether it can stand alone.
10959 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
10960 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
10961 unused declaration.

11033 * doc/bison.texinfo: Add documentation for %expect-rr.
11035 2004-03-08 Paul Eggert <eggert@gnu.org>
11037 Add support for hex token numbers. Suggested by Odd Arild Olsen in
11038 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.

11052 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
11053 compilers. This fixes a problem with Intel's C++ compiler being
11054 chatty, reported by Guido Trentalancia in
11055 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.

11071 token so that it covers all the discarded tokens.
11072 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
11073 it can be called with `%skeleton "lalr1.cc"', and do that.
11075 2004-02-02 Paul Eggert <eggert@twinsun.com>
11077 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
11078 $(top_srcdir)/lib and ../lib. This fixes a bug reported
11079 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
11080 There's no need to mention top_builddir since Automake does that
11082 (INCLUDES): Remove, as Automake says it's obsolescent.
11083 Contents migrated into AM_CPPFLAGS as described above.
11084 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
11086 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11088 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
11089 (yyreportSyntaxError): Handle case where lookahead token is
11092 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11094 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
11095 resulting parsers are compilable with C++.
11097 2003-12-23 Paul Eggert <eggert@twinsun.com>
11099 * config/depcomp, config/install-sh: Sync with Automake 1.8.
11100 * src/output.c (output_skeleton): Rename local var.
11101 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
11102 Bison tokens, as this runs afoul of the 2003-10-07 change that
11103 disallowed NUL bytes in character constants or string literals.
11105 * tests/local.at: Require Autoconf 2.59's Autotest.
11106 * tests/testsuite.at: Don't include local.at, since we now assume
11107 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
11109 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
11110 multiple inclusion warnings.

11124 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
11125 if testsuite doesn't exist.
11127 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
11128 literals, unfortunately.

11130 Complain about NUL bytes in character constants or string literals.
11132 2003-10-05 Paul Eggert <eggert@twinsun.com>
11134 * NEWS: Don't document %no-default-prec, as it's still
11136 * doc/bison.texinfo: Document %no-default-prec only if
11137 the defaultprec flag is set. Normally it's not.
11139 2003-10-04 Paul Eggert <eggert@twinsun.com>
11141 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
11142 non-modifiable lvalue, instead of a modifiable one.
11143 * doc/bison.texinfo (Actions): Document that $$ can
11144 be assigned to. Do not claim that $$ and $N are
11145 array element references: user code should not rely on this.
11147 2003-10-01 Paul Eggert <eggert@twinsun.com>
11149 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.

11179 a typo in the 2003-08-25 patch.
11181 2003-08-27 Akim Demaille <akim@epita.fr>
11183 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify

11205 2003-08-25 Akim Demaille <akim@epita.fr>
11207 When reducing initial empty rules, Bison parser read an initial
11208 location that is not defined. This results in garbage, and that
11209 affects Bison's own parser. Therefore we need (i) to extend Bison
11210 to support a means to initialize this location, and (ii) to use
11211 this CVS Bison to fix CVS Bison's parser.
11213 * src/reader.h, reader.c (epilogue_augment): Remove, replace
11215 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
11216 * src/parse-gram.y: Adjust.
11217 (%initial-action): New.
11218 (%error-verbose): Since we require CVS Bison, there is no reason
11220 * src/scan-gram.l: Adjust.
11221 * src/Makefile.am (YACC): New, to make sure we use our own parser.
11222 * data/yacc.c (yyparse): Use b4_initial_action.
11224 2003-08-25 Akim Demaille <akim@epita.fr>
11226 * doc/bison.texinfo: Don't promote stdout for error messages.
11228 2003-08-25 Akim Demaille <akim@epita.fr>
11230 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
11231 From Alexandre Duret-Lutz.

11244 * data/lalr1.cc (Parser::reduce_print_): New.
11247 2003-08-25 Akim Demaille <akim@epita.fr>
11249 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
11250 error recovery loops. This patch is based on
11251 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
11252 Also, augment the similarity between lalr1.cc and yacc.c.
11253 Note: the locations of error recovery rules are not correct yet.
11255 * data/lalr1.cc: Comment changes to augment the similarity between
11256 lalr1.cc and yacc.c.
11257 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
11258 (yyerrlab1): Remove, but where it used to be (now the bottom part of
11259 yyerrlab), when hitting EOF, pop the whole stack here instead of
11260 merely falling thru the default error handling mechanism.
11261 (yyerrorlab): New label, with the old contents of YYERROR,
11262 plus the following change: pop the stack of rhs corresponding
11263 to the production that invoked YYERROR. That is how Yacc
11264 behaves (required by POSIX).
11265 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
11268 2003-08-25 Akim Demaille <akim@epita.fr>
11270 Tune local.at so that people can "autom4te -l autotest calc.at -o
11271 calc" for instance, to extract a sub test suite.
11273 * tests/testsuite.at: Move the initialization, Autotest version
11274 requirement, and AT_TESTED invocation into...
11275 * tests/local.at: here.
11276 * tests/testsuite.at: Include it for compatibility with Autoconf
11278 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
11281 2003-08-04 Paul Eggert <eggert@twinsun.com>
11283 Rework code slightly to avoid gcc -Wtraditional warnings.
11284 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
11285 The returned value is now stored in *YY0. All callers changed.
11286 * src/output.c (merge_output): Adjust to the above change.
11288 2003-07-26 Paul Eggert <eggert@twinsun.com>
11290 * data/glr.c (YYASSERT): New macro.
11291 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
11292 yyresolveStates, yyprocessOneStack):
11293 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
11294 Derived from a suggestion by Frank Heckenbach.
11296 2003-07-25 Paul Eggert <eggert@twinsun.com>
11298 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
11299 for portability to K&R C (after ansi2knr, presumably). See
11300 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
11301 by Frank Heckenbach, though I have omitted the structure-initialization
11302 part of his glr-knr.diff patch since I recall that the Portable
11303 C Compiler didn't require that change.
11305 Let the user specify how to allocate and free memory.
11306 Derived from a suggestion by Frank Heckenbach in
11307 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
11308 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
11309 All uses of free, malloc, realloc changed to use these macros,
11310 and unnecessary casts removed.
11311 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
11313 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
11315 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
11316 use s.empty() rather than s == "" to test for empty string; see
11317 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
11320 2003-06-25 Akim Demaille <akim@epita.fr>

11324 2003-06-20 Paul Eggert <eggert@twinsun.com>
11326 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
11327 and return properly parenthesized result.
11328 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
11329 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
11330 Remove unnecessary parentheses from uses.

11336 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
11337 yyreportTree): Do not assume that size_t is the same width as int,
11338 when printing sizes. Print sizes using an unsigned format.
11339 Problem reported by Frank Heckenbach in
11340 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
11342 Port to Forte Developer 7 C compiler.
11343 * data/glr.c (struct YYLTYPE): If locations are not being used,
11344 declare a single dummy member, as empty structs do not conform
11346 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
11347 the Forte Developer 7 C compiler complains that end-of-loop
11348 code is not reached.

11362 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
11363 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
11364 Don't use 'index' in comments, as it's a builtin fn on some hosts.
11365 * lib/bitset_stats.c: Include gettext.h unconditionally, as
11366 per recent gettext manual's suggestion.
11367 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
11368 Use prototypes, not old-style definitions.

11388 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
11389 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
11392 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
11393 `How Can I Reset @code{yyparse}', since texinfo does not allow
11394 arbitrary @ in node names.
11396 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
11397 shouldn't be needed according to the gettext 0.12.1 documentation
11398 but which seem to be needed anyway: codeset.m4 glibc21.m4
11399 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
11400 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

11406 Upgrade to CVS gnulib.
11407 * stdbool_.h: File renamed from stdbool.h.in.

11421 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
11422 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
11423 the tests right now.
11424 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
11425 yyerror are declared before use; C99 requires this.
11427 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11429 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
11431 (yyrecoverSyntaxError): Correct the logic for setting and testing
11433 Correct comment on handling EOF.
11434 Allow states with only a default reduction, rather than failing
11435 (I can't quite reconstruct why these were not allowed before).
11437 Fixes to avoid problem that $-N rules in GLR parsers can cause
11438 buffer overruns, corrupting state.
11440 * src/output.c (prepare_rules): Output max_left_semantic_context
11442 * src/reader.h (max_left_semantic_context): New variable declaration.
11443 * src/scan-gram.l (max_left_semantic_context): Define.
11444 (handle_action_dollar): Update max_left_semantic_context.
11445 * data/glr.c (YYMAXLEFT): New definition.
11446 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
11447 (yyresolveAction): Ditto.
11449 Fixes to problems with location handling in GLR parsers reported by
11450 Frank Heckenbach (2003/06/05).
11452 * data/glr.c (YYLTYPE): Make trivial if locations not used.
11453 (YYRHSLOC): Add parentheses, and define only if locations used.
11454 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
11455 locations not used.

11457 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
11459 * tests/cxx-type.at: Exercise location information; update tests
11460 to differentiate output with and without locations.
11461 Remove forward declarations of yylex and yyerror---caused errors
11462 because default YYLTYPE not yet defined.
11463 Change semantic actions to compute strings, rather than printing
11464 them directly (to test proper passing of semantics values). Change
11465 output to prefix notation and update test data and expected results.
11466 (yylex): Track locations.
11467 (stmtMerge): Return value rather than printing, and include arguments
11470 2003-06-03 Paul Eggert <eggert@twinsun.com>
11472 Avoid warnings generated by GCC 2.95.4 when Bison is
11473 configured with --enable-gcc-warnings.
11474 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
11475 yy::]b4_parser_class_name[::translate_,
11476 yy::Stack::operator[] (unsigned),
11477 yy::Stack::operator[] (unsigned) const,
11478 yy::Slice::operator[] (unsigned),
11479 yy::Slice::operator[] (unsigned) const):
11480 Rename local vars to avoid warnings.
11481 * tests/glr-regression.at (Improper handling of embedded actions
11482 and $-N in GLR parsers): Remove unused local variable from yylex.
11483 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
11484 (void) as arg when not pure, since we now assume C89 when building
11485 Bison. Pacify GCC by using parameter.
11487 2003-06-02 Paul Eggert <eggert@twinsun.com>
11489 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
11490 yy::Location::lines, yy::Location::columns): Rename arguments
11491 to avoid shadowing; this removes a warning generated by GCC 3.3.
11493 2003-06-01 Paul Eggert <eggert@twinsun.com>
11495 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
11496 to g++, as GCC 3.3 complains if you do it.
11497 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
11498 everything that WARNING_CFLAGS has, except omit warnings
11499 not suitable for C++.
11500 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
11501 * tests/atlocal.in (CXXFLAGS): New var.
11502 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
11504 Fix a GLR parser bug I reported in February; see
11505 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
11506 The problem was that GLR parsers did not conform to the C standard,
11507 because actions like { $1 = $2 + $3; } expanded to expressions
11508 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11509 to a local variable. The C standard says that expressions
11510 like (var = f ()) + (var = f ()) have undefined behavior.
11511 Another problem was that GCC sometimes issues warnings that
11512 yyfill and its parameters are unused.
11514 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11515 as possibly unused.
11516 (yyfill): New function.
11518 (yyuserAction): Change type of yynormal to bool, so that it matches
11519 the new yyfill signature. Mark it as possibly unused.
11522 Follow up on a bug I reported in February, where a Bison-generated
11523 parser can loop. Provide a test case and a fix for yacc.c. I
11524 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11525 The original bug report is in:
11526 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
11528 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11529 macro's size was becoming unwieldy.
11530 (yyerrlab): Do not discard an empty lookahead symbol, as this
11531 might destroy garbage.
11532 (yyerrorlab): New label, with the old contents of YYERROR,
11533 plus the following change: pop the stack of rhs corresponding
11534 to the production that invoked YYERROR. That is how Yacc
11535 behaves, and POSIX requires this behavior.
11536 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11537 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11538 Define 'alarm' to do nothing if unistd.h is not available.
11539 Add a new rule "exp: '-' error;" to test the above change to
11540 data/yacc.c. Use 'alarm' to abort any test taking longer than
11541 10 seconds, as it's probably looping.
11542 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11543 Also, the new yacc.c generates two fewer diagnostics for an
11546 2003-05-24 Paul Eggert <eggert@twinsun.com>
11548 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
11549 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
11550 This fixes a problem reported by John Bowman when the Compaq/HP
11551 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
11552 -ansi -Wall -gall).
11553 * data/yacc.c (union yyalloc): Likewise.
11554 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
11556 Switch from 'int' to 'bool' where that makes sense.
11558 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
11559 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
11560 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
11561 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
11562 Return or accept bool, not int. All callers changed.
11563 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
11564 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.
11565 * lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_,
11566 bitset_copy_, bitset_op4_cmp, bitset_and_or_cmp_, bitset_andn_or_cmp_,
11567 bitset_or_and_cmp_): Likewise.
11568 * lib/bitset.h (bitset_test, bitset_only_set_p): Likewise.
11569 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,
11570 bitset_stats_test, bitset_stats_empty_p, bitset_stats_disjoint_p,
11571 bitset_stats_equal_p, bitset_stats_subset_p, bitset_stats_and_cmp,
11572 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
11573 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
11574 bitset_stats_or_and_cmp): Likewise.
11575 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
11576 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
11577 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
11578 ebitset_xor_cmp): Likewise.
11579 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
11580 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
11581 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
11582 lbitset_xor_cmp): Likewise.
11583 * lib/bbitset.h: Include <stdbool.h>.
11584 (struct bitset_vtable): The following members now return bool, not
11585 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
11586 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
11588 * src/conflicts.c (count_rr_conflicts): Likewise.
11589 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
11591 * lib/ebitset.c (ebitset_obstack_init): Likewise.
11592 * lib/lbitset.c (lbitset_obstack_init): Likewise.
11593 * src/getargs.c (debug_flag, defines_flag, locations_flag,
11594 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
11595 graph_flag): Likewise.
11596 * src/getargs.h (debug_flag, defines_flag, locations_flag,
11597 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
11598 graph_flag): Likewise.
11599 * src/output.c (error_verbose): Likewise.
11600 * src/output.h (error_verbose): Likewise.
11601 * src/reader.c (start_flag, typed): Likewise.
11602 * src/reader.h (typed): Likewise.

11604 (long_options, getargs): Use it.
11605 * src/lalr.c (build_relations): Use bool, not int.
11606 * src/nullable.c (nullable_compute): Likewise.
11607 * src/print.c (print_reductions): Likewise.
11608 * src/tables.c (action_row, pack_vector): Likewise.
11609 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
11610 * src/output.c (prepare): Use it.
11611 * src/output.c (token_definitions_output,
11612 symbol_destructors_output, symbol_destructors_output): Use string,
11613 not boolean integer, to keep track of whether to output separator.
11614 * src/print_graph.c (print_core): Likewise.
11615 * src/state.c (state_rule_lookaheads_print): Likewise.
11617 * config/install-sh: Sync from automake 1.7.5.
11619 2003-05-14 Paul Eggert <eggert@twinsun.com>
11621 * src/parse-gram.y (rules_or_grammar_declaration): Require a
11622 semicolon after a grammar declaration, in the interest of possible
11623 future changes to the Bison input language.
11624 Do not allow a stray semicolon at the start of the grammar.
11625 (rhses.1): Allow one or more semicolons after any rule, including
11626 just before "|" as required by POSIX.
11627 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
11630 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11632 %parse-param support for lalr1.cc.
11634 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
11635 b4_cc_constructor_calls, b4_cc_constructor_call,
11636 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
11638 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
11639 parse-param arguments.
11640 (yy::b4_parser_class_name): Declare instance variables to
11641 hold parse-param arguments.
11642 * tests/calc.at: s/value/semantic_value/ because value clashes
11643 with a member of yy::b4_parser_class_name. Adjust C++ code
11644 to handle %parse-param. Enable %parse-param test in C++.
11646 2003-05-12 Paul Eggert <eggert@twinsun.com>
11648 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
11649 English a bit. Fix fclose typo. Change "const char" to "char
11650 const", and use ANSI C rather than K&R for "main". Suggest
11651 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
11652 and suggest yy_switch_to_buffer.
11654 2003-05-05 Paul Eggert <eggert@twinsun.com>
11656 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
11657 C89. This avoids a diagnostic on compilers that define __STDC__
11658 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
11659 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11661 2003-05-03 Paul Eggert <eggert@twinsun.com>
11663 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
11664 Do not overrun array bounds.
11665 This should fix a bug reported today by Olatunji Oluwabukunmi in
11666 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
11668 2003-04-29 Akim Demaille <akim@epita.fr>
11670 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
11671 * src/getargs.c, src/getargs.h: here, as bool, not int.
11672 (nondeterministic_parser): New.
11673 * src/parse-gram.y, src/scan-gram.l: Support
11674 %nondeterministic-parser.
11675 * src/output.c (prepare): Use nondeterministic_parser instead
11676 of glr_parser where appropriate.
11677 * src/tables.c (conflict_row, action_row, save_row)
11678 (token_actions, token_actions, pack_vector): Ditto.
11680 2003-04-29 Akim Demaille <akim@epita.fr>
11682 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
11684 2003-04-29 Akim Demaille <akim@epita.fr>
11686 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
11687 with %pure-parser and %locations to exercise the patch from Yakov
11690 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
11692 * data/yacc.c: (b4_lex_param): Corrected for the case where
11693 %lex-param is provided and %pure-parser isn't.
11695 2003-04-27 Paul Eggert <eggert@twinsun.com>
11697 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
11698 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
11699 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
11700 if it is not defined.
11701 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
11703 2003-04-26 Paul Eggert <eggert@twinsun.com>
11705 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
11706 Declare to be of type suitable for the ninf value itself, not of
11707 type suitable for the corresponding table, since the latter might
11708 be unsigned but the ninf value might be negative. This fixes a
11709 bug reported by Alexandre Duret-Lutz in
11710 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
11712 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
11713 invokes it. We shouldn't invoke it twice because it will attempt
11714 to put error.o in the archive twice. This fixes a glitch reported
11715 by Martin Mokrejs in
11716 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11718 2003-04-21 Paul Eggert <eggert@twinsun.com>
11720 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
11723 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
11725 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
11726 Fix obvious typo that results in uncompilable GLR parsers
11727 when both %pure-parser and %locations are used. (trivial change)
11729 2003-04-17 Paul Eggert <eggert@twinsun.com>
11731 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
11732 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
11733 Do not insert the expected token via unput, as this runs afoul
11734 of a POSIX-compatibility bug in flex 2.5.31.
11735 All uses changed to BEGIN the parent state,
11736 since we no longer insert the expected token via unput.
11737 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
11738 that is no longer emitted after the above change.
11740 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
11741 the first one. This change is from Paul Hilfinger, and it fixes
11742 regression reported by Werner Lemberg in
11743 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
11745 (resolve_sr_conflict): Don't invoke state_errs_set
11746 unless one or more tokens have been explicitly made errors.
11747 Otherwise, the above change causes Bison to abort.
11749 * tests/existing.at (GNU pic Grammar): New test case, taken from
11752 2003-03-31 Akim Demaille <akim@epita.fr>
11754 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
11756 2003-03-31 Akim Demaille <akim@epita.fr>
11758 * src/output.c (prepare_symbols): Avoid trailing spaces in the
11761 2003-03-31 Akim Demaille <akim@epita.fr>
11763 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
11764 From Paul Hilfinger.
11766 2003-03-29 Akim Demaille <akim@epita.fr>
11768 * m4/error.m4: Do not put under dynamic conditions some code which
11769 expansion is under static control.
11771 2003-03-29 Akim Demaille <akim@epita.fr>
11773 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
11775 2003-03-29 Akim Demaille <akim@epita.fr>
11777 * doc/bison.texinfo (Strings are Destroyed): New.
11779 2003-03-13 Paul Eggert <eggert@twinsun.com>
11781 * .cvsignore: Add configure.lineno.
11782 * src/.cvsignore: Add yacc.
11783 * tests/.cvsignore: Add testsuite.log.
11784 * doc/fdl.texi: Sync with latest FSF version.
11786 2003-03-12 Paul Eggert <eggert@twinsun.com>
11788 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
11789 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
11790 cursor, instead of leaving it undefined. This fixes a bug
11791 reported by Tim Van Holder in
11792 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
11793 * tests/input.at (Torturing the Scanner): Test the scanner on
11794 an empty input file, which was Tim Van Holder's test case.
11796 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
11797 <sys/resource.h> can be included, include sys/time.h and
11798 sys/times.h first, if available. This works around the SunOS
11799 4.1.4 porting bug reported by Bruce Becker in
11800 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
11802 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
11803 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
11804 AC_HEADER_SYS_WAIT.
11806 Merge changes from gnulib. This was prompted because the CVS
11807 snapshot didn't build on Solaris 7 due to strnlen problems.
11809 These changes need to be merged back into gnulib:
11810 * lib/hash.c: Include <stdbool.h> unconditionally.
11811 * m4/onceonly.m4 (m4_quote): New macro.
11812 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
11813 Quote AC_FOREACH variable-expansions properly.
11814 The 2003-01-03 obstack.h change also needs merging.
11815 {end of changes requiring merging}
11817 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
11818 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
11819 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
11820 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
11821 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
11822 New files, imported from gnulib.
11823 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
11826 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
11827 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
11830 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
11832 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
11833 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
11834 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
11835 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
11836 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
11837 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
11838 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
11839 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
11840 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
11841 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
11842 (jm_PREREQ_ARGMATCH): Remove.
11843 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
11844 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
11846 * src/system.h: Include <stdbool.h> unconditionally.
11848 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
11849 assuming at least C89 in the bitset code for some time now.
11851 2003-03-03 Akim Demaille <akim@epita.fr>
11855 2003-03-02 Akim Demaille <akim@epita.fr>
11857 * doc/bison.texinfo (Table of Symbols): Reactivate the
11858 documentation for %lex-param, and %parse-param.
11860 2003-03-02 Akim Demaille <akim@epita.fr>
11862 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
11863 generate verbose error messages.
11864 Use the number of tokens as an upper bound in yytname, as it
11865 cannot be a non terminal.
11867 2003-03-02 Akim Demaille <akim@epita.fr>
11869 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
11872 2003-03-02 Akim Demaille <akim@epita.fr>
11874 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
11875 Use them to exercise yycheck overrun.
11876 Based on Andrew Suffield's grammar.
11878 2003-03-02 Akim Demaille <akim@epita.fr>
11880 Create tests/local.at for Bison generic testing macros.
11882 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
11883 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
11885 * tests/calc.at (AT_CHECK_CALC): Adjust.
11886 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
11887 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
11888 * tests/local.at: here.
11889 (AT_COMPILE_CXX): Tags the tests using it as c++.
11890 Ignore the test if CXX is not functional.
11892 2003-03-01 Paul Eggert <eggert@twinsun.com>
11894 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
11895 not loc->end, since loc->end might contain garbage and this leads
11896 to undefined behavior on some platforms.
11897 (id_loc, token_start): Use (IF_LINTed) initial values that do not
11898 depend on *loc, so that the reader doesn't give the the false
11899 impression that *loc is initialized.
11900 (<INITIAL>"%%"): Do not bother setting code_start, since its value
11901 does not survive the return.
11903 2003-03-01 Akim Demaille <akim@epita.fr>
11905 * src/scan-gram.l (code_start): Always initialize it when entering
11906 into yylex, as SC_EPILOGUE is activated *before* the corresponding
11907 yylex invocation. An alternative would be making it static, but
11908 then it starts with the second %%'s beginning, instead of its end.
11910 2003-02-28 Paul Eggert <eggert@twinsun.com>
11912 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
11913 around a UnixWare 7.1.1 porting bug reported by John Hughes in
11914 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
11916 2003-02-26 Paul Eggert <eggert@twinsun.com>
11918 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
11919 Remove Sequent/Pyramid discussion (nobody uses them any more).
11920 Merge VMS and MS-DOS discussion; these ports may well be dead
11921 but let's keep mentioning them for now. Put <> around email
11922 addresses. Add copyright notice.
11924 2003-02-24 Paul Eggert <eggert@twinsun.com>
11926 * data/glr.c (yy_reduce_print): yylineno -> yylno,
11927 to avoid collision with flex use of yylineno.
11928 Problem reported by Bruce Lilly in
11929 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

11933 * config/depcomp: Sync with Automake 1.7.3.
11935 2003-02-21 Akim Demaille <akim@epita.fr>
11937 * data/lalr1.cc: Use temporary variables instead of casts to
11938 change integer types.
11939 Suggested by Paul Eggert.
11941 2003-02-21 Akim Demaille <akim@epita.fr>
11943 * doc/bison.texinfo: Use "location" consistently to refer to @n,
11944 to avoid confusions with lalr1.cc's notion of Position.
11945 Suggested by Paul Eggert.
11947 2003-02-20 Akim Demaille <akim@epita.fr>
11949 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
11950 before initial_columns.
11951 (location.hh): Use consistent variable names when defining the
11953 Use "last" so that we subtract from Positions, not from unsigned.
11955 2003-02-20 Akim Demaille <akim@epita.fr>
11957 * data/lalr1.cc (position.hh): New subfile, including the extended
11958 and Doxygen'ed documentation of class Position.
11959 (location.hh): Use it.
11960 Document a` la Doxygen.
11961 With the help of Benoit Perrot.
11963 2003-02-20 Akim Demaille <akim@epita.fr>
11965 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
11967 Redefine AT_YYERROR_SEES_LOC_IF using it.
11968 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
11970 Don't use the location in yy::Parser::error_ and
11971 yy::Parser::print_ when not %locations.
11972 Activate more lalr1.cc tests.
11974 2003-02-19 Akim Demaille <akim@epita.fr>
11976 * data/lalr1.cc: When displaying a line number, be sure to make it
11979 2003-02-19 Akim Demaille <akim@epita.fr>
11981 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
11983 (YYABORT, YYACCEPT, YYERROR): New.
11984 * tests/calc.at: Renable the lalr1.cc test.
11986 2003-02-19 Akim Demaille <akim@epita.fr>
11988 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
11989 error recovery, mixing with/without pops and discarding of the
11992 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
11994 2003-02-17 Paul Eggert <eggert@twinsun.com>
11996 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
11997 * tests/testsuite.at (AT_COMPILE): Use them.
11998 This fixes the testsuite problem reported by Robert Lentz in
11999 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
12001 2003-02-12 Paul Eggert <eggert@twinsun.com>
12003 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
12004 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
12005 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
12006 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
12007 Check for malloc failure, for consistency with yacc.c.
12008 (yytname_size): Remove, for consistency with yacc.c.
12010 The bug still remains in data/lalr1.cc, as I didn't have time
12013 2003-02-06 Akim Demaille <akim@epita.fr>
12015 * configure.ac (GXX): Rename as...
12016 (CXX): this, to keep the original Autoconf semantics.
12018 * data/lalr1.cc: Fix b4_copyright invocations.
12019 If YYDEBUG is not defined, don't depend upon name_ being defined.
12020 (location.hh): Include string and iostream.
12021 (Position::filename): New member.
12022 (Position::Position ()): New.
12023 (operator<< (Position)): New.
12024 (operator- (Position, int)): New.
12025 (Location::first, Location::last): Rename as...
12026 (Location::begin, Location::end): these, to mock the conventional
12028 (operator<< (Location)): New.
12029 * tests/atlocal.in (CXX): New.
12030 * tests/testsuite.at (AT_COMPILE_CXX): New.
12031 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
12032 locations in a more synthetic way.
12033 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
12035 Adjust the C locations to match those from Emacs: first column is
12037 Change all the expected results.
12038 Conform to the GCS: simplify the locations when applicable.
12039 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
12040 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
12041 these CPP macros with the m4 macros new defined by...
12042 (AT_CHECK_PUSHDEFS): this, i.e.:
12043 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
12044 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
12046 (AT_CHECK_POPDEFS): Undefine them.
12047 (AT_CHECK_CALC_LALR1_CC): New.
12048 Use it for the first lalr1.cc test.
12050 2003-02-04 Akim Demaille <akim@epita.fr>
12052 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
12053 Location as is defined.
12055 2003-02-04 Akim Demaille <akim@epita.fr>
12057 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
12058 name_ being defined.
12060 2003-02-03 Paul Eggert <eggert@twinsun.com>
12062 * src/gram.h (start_symbol): Remove unused decl.
12064 Use more-consistent naming conventions for local vars.
12066 * src/derives.c (derives_compute): Change type of local var from
12067 int to rule_number.
12068 * src/gram.c (grammar_rules_partial_print): Likewise.
12069 * src/print.c (print_core): Likewise.
12070 * src/reduce.c (reduce_grammar_tables): Likewise.
12072 * src/gram.c (grammar_dump): Change name of item_number *
12073 local var from r to rp.
12074 * src/nullable.c (nullable_compute): Likewise.
12076 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
12078 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
12079 for symbol or symbol_number var.
12080 * src/reader.c (grammar_start_symbol_set): Likewise.
12081 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
12083 * src/state.c (transitions_to): Likewise.
12084 * src/state.h: Likewise.
12085 * src/tables.c (symbol_number_to_vector_number): Likewise.
12087 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
12090 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
12093 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
12096 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
12097 Use str, not s, for char * var. Use ch, not c, for character var.
12098 Use size for size var.
12100 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
12102 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
12104 * src/uniqstr.h: Likewise.
12106 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
12107 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
12108 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
12109 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
12110 param to have same name as that of enum, so that we don't use
12111 "s" to stand for a non-state.
12113 2003-02-02 Akim Demaille <akim@epita.fr>
12115 * src/scan-skel.l: Scan more than one inert character per yylex
12118 2003-02-01 Paul Eggert <eggert@twinsun.com>
12122 * po/LINGUAS: Add ms.
12124 2003-01-30 Akim Demaille <akim@epita.fr>
12126 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
12128 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12130 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
12133 Changes in response to error report by S. Eken: GLR mode does not
12134 handle negative $ indices or $ indices in embedded rules correctly.
12135 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
12137 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
12138 (b4_rhs_location): Ditto.
12139 (yyfill): New function to copy from stack tree into array
12141 (yyuserAction): Modify to allow incremental move of semantic values
12142 to rhs array when in GLR mode.
12143 Define YYFILL to use in user-defined actions to fill semantic array
12145 Remove dummy use of yystack, as there is now a guaranteed use.
12146 (yydoAction): Modify to allow incremental move of semantic values
12147 to rhs array when in GLR mode.
12148 (yyresolveAction): Ditto.
12149 (yyglrShiftDefer): Update comment.
12150 (yyresolveStates): Use X == NULL for pointers, not !X.
12151 (yyglrReduce): Ditto.
12152 (yydoAction): Ditto
12154 * tests/glr-regr1.at: Rename to ...
12155 * tests/glr-regression.at: Add new regression test for the problems
12156 described above (adapted from S. Eken).
12157 Update copyright notice.
12158 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
12159 * tests/Makefile.am: Ditto.
12161 2003-01-28 Paul Eggert <eggert@twinsun.com>
12163 * data/lalr1.cc: Do not use @output_header_name@ unless
12164 b4_defines_flag is set. This fixes two bugs reported by
12166 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
12167 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
12169 2003-01-21 Paul Eggert <eggert@twinsun.com>
12171 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
12172 we don't need to worry about yyerrlab1 being reported as an
12173 "unused label" by non-GCC C compilers. The downside is that if
12174 locations are used then a couple of statements are duplicated each
12175 time YYERROR is invoked, but the upside is that the warnings
12177 (yyerrlab1): Move code to YERROR.
12178 (yyerrlab2): Remove. Change uses back to yyerrlab1.
12179 This reverts some of the 2002-12-27 change.
12181 2003-01-17 Paul Eggert <eggert@twinsun.com>
12183 * src/output.c (symbol_printers_output): Fix typo that led
12184 to core dump. Problem reported by Antonio Rus in
12185 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
12187 2003-01-13 Akim Demaille <akim@epita.fr>,
12188 Quoc Peyrot <chojin@lrde.epita.fr>,
12189 Robert Anisko <anisko_r@lrde.epita.fr>
12191 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
12192 when the stacks contain one element, as the loop would otherwise
12193 free the last state, and then use the top state (the one we just
12194 popped). This means that the initial elements will not be freed
12195 explicitly, as is the case in yacc.c; it is not a problem, as
12196 these elements have fake values.
12198 2003-01-11 Paul Eggert <eggert@twinsun.com>
12200 * NEWS: %expect-violations are now just warnings, reverting
12201 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
12202 bootstrapping problem reported by Matthias Klose; see
12203 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
12204 * src/conflicts.c (conflicts_print): Likewise.
12205 * tests/conflicts.at (%expect not enough, %expect too much,
12206 %expect with reduce conflicts): Likewise.
12207 * doc/bison.texinfo (Expect Decl): Document this. Also mention
12208 that the warning is enabled if the number of conflicts changes
12209 (not necessarily increases).
12211 * src/getargs.c (version): Update copyright year.
12213 2003-01-09 Akim Demaille <akim@epita.fr>
12215 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
12217 2003-01-08 Paul Eggert <eggert@twinsun.com>
12219 * Makefile.maint (WGETFLAGS):
12220 New macro, containing "-C off" to disable proxy caches.
12221 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
12222 (rel-check): Use $(WGET) instead of wget.
12224 2003-01-06 Paul Eggert <eggert@twinsun.com>
12226 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
12227 the GLR paper of Scott, Johnstone and Hussain.
12229 2003-01-04 Paul Eggert <eggert@twinsun.com>
12231 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
12232 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
12233 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
12234 (EXTRA_LIBRARIES): New var, for liby.a.
12235 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
12236 (EXTRA_SCRIPTS): New var, for yacc.
12238 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
12239 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
12240 Problem reported by Nelson H. F. Beebe.
12242 2003-01-03 Paul Eggert <eggert@twinsun.com>
12244 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
12245 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
12246 when compiling Bison 1.875's `bitset bset = obstack_alloc
12247 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
12249 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
12250 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
12251 grow to a huge size with typical invocation.
12253 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
12254 Use the pattern recommended by Autoconf 2.57, except also protect
12255 against double-definition.
12256 * src/system.h: Likewise.
12257 Portability issues reported by Nelson H. F. Beebe.
12259 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
12260 All uses changed. Provide a definition in both C and C++.
12261 (yytrue, yyfalse): Define even if defined (__cplusplus).
12263 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
12264 Reported by Nelson H. F. Beebe.
12266 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
12268 2003-01-02 Paul Eggert <eggert@twinsun.com>
12270 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
12271 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
12272 Bug reported by Nelson H. F. Beebe.
12274 2003-01-01 Paul Eggert <eggert@twinsun.com>
12278 2002-12-30 Paul Eggert <eggert@twinsun.com>
12280 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
12282 (<INITIAL>","): Here. This causes stray "," to be treated
12285 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
12286 last brace in braced code when not in Yacc mode, for compatibility
12287 with Bison 1.35. This resurrects the 2001-12-15 patch to
12290 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
12291 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
12293 2002-12-28 Paul Eggert <eggert@twinsun.com>
12295 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
12296 that of SYM's type. This fixes Debian bug 168069, reported by
12299 2002-12-28 Paul Eggert <eggert@twinsun.com>
12303 Switch back to the Yacc style of conflict reports, undoing some
12304 of the 2002-07-30 change.
12305 * doc/bison.texinfo (Understanding): Use Yacc style for
12306 conflict reports. Also, use new way of locating rules.
12307 * src/conflicts.c (conflict_report):
12308 Renamed from conflict_report_yacc, removing the old
12309 'conflict_report'. Translate the entire conflict report at once,
12310 so that we don't assume that "," has the same interpretation in
12312 (conflicts_output): Use Yacc-style conflict report for each state,
12313 instead of our more-complicated style.
12314 (conflicts_print): Use Yacc-style conflict report, except print
12315 the input file name when not emulating Yacc.
12316 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
12317 Conflicted Reduction, %expect not enough, %expect too much,
12318 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
12319 * tests/existing.at (GNU Cim Grammar): Likewise.
12320 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
12322 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
12323 fatal): Don't invoke fflush; it's not needed and it might even be
12324 harmful for stdout, as stdout might not be open.
12325 * src/reduce.c (reduce_print): Likewise.
12327 2002-12-27 Paul Eggert <eggert@twinsun.com>
12329 Fix a bug where error locations were not being recorded correctly.
12330 This problem was originally reported by Paul Hilfinger in
12331 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
12333 * data/yacc.c (yyparse): New local var yylerrsp, to record the
12334 top of the location stack's error locations.
12335 (yyerrlab): Set it. When discarding a token, push its location
12336 onto yylerrsp so that we don't lose track of the error's end.
12337 (yyerrlab1): Now is only the target of YYERROR, so that we can
12338 properly record the location of the action that failed. For GCC
12339 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
12340 GCC warning about yyerrlab1 being unused if YYERROR is unused.
12341 (yyerrlab2): New label, which yyerrlab now falls through to.
12342 Compute the error's location by applying YYLLOC_DEFAULT to
12343 the locations of all the symbols that went into the error.
12344 * doc/bison.texinfo (Location Default Action): Mention that
12345 YYLLOC_DEFAULT is also invoked for syntax errors.
12346 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
12347 Error locations include the locations of all the tokens that were
12348 discarded, not just the last token.
12350 2002-12-26 Paul Eggert <eggert@twinsun.com>
12352 * src/files.c: Include quote.h.
12353 (compute_output_file_names): Warn if we detect conflicting
12354 outputs to the same file. This should catch the misunderstanding
12355 exemplified by Debian Bug 165349, reported by Bruce Stephens..
12357 * src/conflicts.c (conflicts_print): If the user specifies
12358 "%expect N", report an error if there are any reduce/reduce
12359 conflicts. This is what the manual says should happen.
12360 This fixes Debian bug 130890, reported by Anthony DeRobertis.
12361 * tests/conflicts.at (%expect with reduce conflicts): New test.
12363 Don't use m4_include on relative file names, as it doesn't work as
12364 desired if there happens to be a file with that name under ".".
12366 * m4sugar/version.m4: Remove; it was included but it wasn't used.
12367 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
12368 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
12369 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
12370 * src/output.c (output_skeleton): Use full path names when
12371 specifying a file to include; don't rely on include path, as
12372 it's unreliable when the working file contains a file with
12375 2002-12-25 Paul Eggert <eggert@twinsun.com>
12377 Remove obsolete references to bison.simple and bison.hairy.
12378 Problem mentioned by Aubin Mahe in
12379 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
12380 * data/glr.c: Comment fix.
12381 * doc/bison.1: Remove references. Also, mention "yacc".
12383 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
12386 * src/parse-gram.y (declaration): Use enum "report_states" rather
12387 than its numeric value 1.
12389 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
12390 opening a new one. This fixes Debian bug 165349, reported by
12393 2002-12-24 Paul Eggert <eggert@twinsun.com>
12397 * Makefile.maint (cvs-update): Don't assume that the shell
12398 supports $(...), as Solaris sh doesn't.
12400 * src/parse-gram.y (lloc_default): Remove test for empty
12401 nonterminals at the end, since it didn't change the result.
12403 2002-12-24 Paul Eggert <eggert@twinsun.com>
12405 If the user does not define YYSTYPE as a macro, Bison now declares it
12406 using typedef instead of defining it as a macro. POSIX requires this.
12407 For consistency, YYLTYPE is also declared instead of defined.
12409 %union directives can now have a tag before the `{', e.g., the
12410 directive `%union foo {...}' now generates the C code
12411 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12412 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12413 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12414 instead of `yyltype'.
12416 `yystype' and `yyltype' are now obsolescent macros instead of being
12417 typedefs or tags; they are no longer documented and will be
12418 withdrawn in a future release.
12420 * data/glr.c (b4_location_type): Remove.
12421 (YYSTYPE): Renamed from yystype.
12422 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
12423 (struct YYLTYPE): Renamed from struct yyltype.
12424 (YYLTYPE): Renamed from yyltype.
12425 (yyltype, yystype): New (and obsolescent) macros,
12426 for backward compatibility.
12427 * data/yacc.c: Likewise.
12429 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
12430 does not specify a union tag. This is for compatibility with
12433 * src/parse-gram.y (add_param): 2nd arg is now char * not char
12434 const *, since it is now modified by stripping surrounding { }.
12435 (current_braced_code): Remove.
12436 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
12437 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
12438 trailing " {...}". Now of type <chars>.
12439 (grammar_declaration): Adjust to bundled tokens.
12440 (code_content): Remove; stripping is now done by add_param.
12441 (print_token_value): Print contents of bundled tokens.
12442 (token_name): New function.
12444 * src/reader.h (braced_code, current_braced_code): Remove.
12445 (token_name): New decl.
12447 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
12448 token_type, not braced_code code_kind. All uses changed.
12449 (SC_PRE_CODE): New state, for scanning after a keyword that
12450 has (or usually has) an immediately-following braced code.
12451 (token_type): New local var, to keep track of which token type
12452 to return when scanning braced code.
12453 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
12454 <INITIAL>"%parse-param", <INITIAL>"%printer",
12455 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
12456 instead of returning a token type immediately.
12457 (<INITIAL>"{"): Set token type.
12458 (<SC_BRACED_CODE>"}"): Use it.
12459 (handle_action_dollar, handle_action_at): Now returns bool
12460 indicating success. Fail if ! current_rule; this prevents a core dump.
12461 (handle_symbol_code_dollar, handle_symbol_code_at):
12462 Remove; merge body into caller.
12463 (handle_dollar, handle_at): Complain in invalid contexts.
12465 * NEWS, doc/bison.texinfo: Document the above.
12466 * NEWS: Fix years and program names in copyright notice.
12468 2002-12-17 Paul Eggert <eggert@twinsun.com>
12470 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
12471 Reporting, Table of Symbols): Omit mentions of %lex-param and
12472 %parse-param from the documentation for now.
12474 2002-12-15 Paul Eggert <eggert@twinsun.com>
12476 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
12477 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
12478 lookahead symbol, and which sets yychar in parser actions) and it
12479 disagreed with the Bison documentation. Bug
12480 reported by Andrew Walrond.
12482 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
12483 as the caller now does that.
12484 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
12485 (YYEMPTY): Parenthesize right hand side, since others use it.
12486 (yyparse): Don't assume that our generated code is the only code
12489 2002-12-13 Paul Eggert <eggert@twinsun.com>
12493 POSIX requires a "yacc" command.
12494 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
12495 (MOSTLYCLEANFILES): Add yacc.
12497 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
12498 as an alias for bison y.
12500 * po/LINGUAS: Add da.
12502 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
12503 problem with latest <getopt.h>.
12504 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
12506 * doc/fdl.texi: Upgrade to 1.2.
12507 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
12508 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
12509 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
12511 * config/install-sh: Sync with autotools.
12513 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
12514 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12515 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
12516 locations are requested.
12517 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
12518 locations are requested.
12520 2002-12-12 Paul Eggert <eggert@twinsun.com>
12522 Remove unportable casts and storage allocation tricks.
12523 While we're at it, remove almost all casts, since they
12524 usually aren't needed and are a sign of trouble.
12526 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
12528 * src/derives.c (derives_compute): Do not subtract NTOKENS from
12529 the pointer DSET returned by malloc; this isn't portable.
12530 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
12531 Similarly for DERIVES.
12532 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
12533 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
12534 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
12536 * src/derives.c (derives_compute): Do not bother invoking
12537 int_of_rule_number, since rule numbers are integers.
12539 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
12540 rather than XMALLOC (char, N).
12542 * src/files.c (filename_split): Rewrite to avoid cast.
12544 * src/gram.h (symbol_number_as_item_number,
12545 item_number_as_symbol_number, rule_number_as_item_number,

12547 Now inline functions rather than macros, to avoid casts.
12548 * src/state.h (state_number_as_int): Likewise.
12549 * src/tables.c (state_number_to_vector_number,
12550 symbol_number_to_vector_number): Likewise.
12552 * src/gram.h (int_of_rule_number): Remove; no longer used.
12554 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
12555 since the resulting storage is always stored into.
12557 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
12560 * src/muscle_tab.c (muscle_m4_output):
12561 Now inline. Return bool, not int.
12562 * src/state.c (state_compare): Likewise.
12563 * src/symtab.c (symbol_check_defined,
12564 symbol_check_alias_consistency, symbol_pack, symbol_translation,

12572 symbol_check_alias_consistency_processor, symbol_pack_processor,
12573 symbol_translation_processor, hash_symbol_comparator,
12574 hash_symbol_hasher): Likewise.
12575 * src/uniqstr.c (uniqstr_print_processor): Likewise.
12576 * src/muscle_tab.c (muscles_m4_output):
12577 Use new functions instead of casting old functions unportably.
12578 * src/state.c (state_hash_new): Likewise.
12579 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
12580 symbols_token_translations_init):
12582 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
12584 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
12585 var instead of casting to long, to avoid casts.
12586 (prepare_states): Use MALLOC rather than alloca, so that we don't
12587 have to worry about alloca.
12588 * src/state.c (state_hash_lookup): Likewise.
12590 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
12591 local var instead of casting to unsigned char, to avoid casts.
12593 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
12594 STATE_ALLOC): Remove.
12595 (transitions_new, errs_new, reductions_new, state_new): Use malloc
12596 rather than calloc, and use offsetof to avoid allocating slightly
12598 (state_new): Initialize all members.
12600 * src/state.c (state_hash): Use unsigned accumulator, not signed.
12602 * src/symtab.c (symbol_free): Remove; unused.
12603 (symbol_get): Remove cast in lhs of assignment.

12605 hashing-related ones.
12607 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
12608 (symbol_processor): Remove.
12609 (symbols_do): Remove decl; now static.
12611 * src/system.h (alloca): Remove; decl no longer needed.
12612 (<stddef.h>): Include, for offsetof.
12613 (<inttypes.>, <stdint.h>): Include if available.
12614 (uintptr_t): New type, if system lacks it.
12615 (CALLOC, MALLOC, REALLOC): New macros.
12616 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
12619 * src/tables.c (table_size): Now int, to pacify GCC.
12620 (table_grow, table_ninf_remap): Use signed table size.
12621 (save_row): Don't bother initializing locals when not needed.

12632 2002-12-09 Paul Eggert <eggert@twinsun.com>
12634 Change identifier spellings to avoid collisions with names
12635 that are reserved by POSIX.
12637 Don't use names ending in _t, since POSIX reserves them.
12638 For consistency, remove _e and _s endings -- they're weren't
12639 needed to remove ambiguity. All uses changed.
12640 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
12641 turn was just renamed from struniq_t.
12642 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
12643 which in turn was just renamed from struniq_processor_t.
12644 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
12645 in turn was renamed from hash_compare_struniq_t.

12715 value_t_as_yystype -> value_as_yystype.
12717 Don't include <errno.h> in the mainstream code, since it
12718 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
12719 * lib/get-errno.c, lib/get-errno.h: New files.
12720 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

12730 (TAB_EXT): Renamed from EXT_TAB.

12733 Avoid str[a-z]*, since <string.h> reserves that name space.
12734 Change all instances of "struniq" in names to "uniqstr", and
12735 likewise for "STRUNIQ" and "UNIQSTR".
12736 * src/uniqstr.c: Renamed from src/struniq.c.
12737 * src/uniqstr.h: Renamed from src/struniq.h.

12748 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
12749 (N_EXPAND): Renamed from N_STRETCH.

12761 (ACTION_MAX): Remove; unused.
12762 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.

12773 for consistency with other names.
12774 * lib/timevar.h (timevar_report): New decl.
12775 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
12778 Sort include-file uses.
12780 Reorder all include files under src to be in the order "system.h".
12781 then the ../lib include files in angle brackets (alphabetized),
12782 then the . include files in double-quotes (alphabetized). Fix
12783 dependency breakages encountered in this process, as follows:
12784 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
12785 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
12786 * src/state.h: Include "symtab.h".
12788 2002-12-08 Paul Eggert <eggert@twinsun.com>
12790 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
12791 since this causes problems when __file__ contains character
12792 sequences like "@" that are treated specially by src/scan-skel.l.
12793 Instead, just use the file's basename. This fixes the bug
12794 reported by Martin Mokrejs in
12795 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
12797 2002-12-06 Paul Eggert <eggert@twinsun.com>
12799 Add support for rules that do not have trailing semicolons, as

12807 * src/location.h: Do not include <quotearg.h>; no longer needed.
12808 (boundary): New type.
12809 (location_t): Use it. This allows locations to span file boundaries.
12810 All member uses changed: file -> start.file or end.file (as needed),

12817 (location_print): New decl.
12818 * src/parse-gram.y (lloc_default): New function, which handles

12829 (semi_colon.opt): Remove.
12830 * src/reader.h: Include location.h.
12831 (scanner_cursor): New decl.
12832 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
12834 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
12836 (STEP): Remove. No longer needed, now that adjust_location does
12837 the work. All uses removed.
12838 (scanner_cursor): New var.
12839 (adjust_location): Renamed from extend_location. It now sets
12840 *loc and adjusts the scanner cursor. All uses changed.
12841 Don't bother testing for CR.
12842 (handle_syncline): Remove location arg; now updates scanner cursor.
12843 All callers changed.
12844 (unexpected_end_of_file): Now accepts start boundary of token or
12845 comment, not location. All callers changed. Update scanner cursor,
12847 (SC_AFTER_IDENTIFIER): New state.
12848 (context_state): Renamed from c_context. All uses changed.
12849 (id_loc, code_start, token_start): New local vars.
12850 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
12851 processing of Yacc white space and equivalents here.
12852 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
12853 instead of returning ID immediately, since we need to search for
12854 a subsequent colon.
12855 (<INITIAL>"'", "\""): Save token_start.
12856 (<INITIAL>"%{", "{", "%%"): Save code_start.
12857 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
12858 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
12859 BEGIN context_state at end, not INITIAL.
12860 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
12861 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
12862 Return correct token start.
12863 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
12864 the start of a character, string or multiline comment is found.
12865 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
12866 Reduction): Adjust reported locations to match the more-precise
12867 results now expected.
12868 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
12869 * tests/reduce.at (Useless Rules, Reduced Automaton,
12870 Underivable Rules): Likewise.
12871 * tests/regression.at (Invalid inputs): No longer `expecting ";"
12872 or "|"' now that so many other tokens are allowed by the new grammar.
12874 * src/complain.h (current_file): Remove duplicate decl;
12875 current_file is now owned by files.h.
12876 * src/complain.c, src/scan-gram.l: Include files.h.
12878 2002-12-06 Paul Eggert <eggert@twinsun.com>
12880 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
12881 promotes to int; it might be unsigned int.
12882 * data/yacc.c (yy_reduce_print): Likewise.
12884 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
12885 be #defined in the prologue, not in the Bison declarations.
12886 This fixes Debian Bug 102878, reported by Shaul Karl.
12888 2002-12-02 Paul Eggert <eggert@twinsun.com>
12890 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
12891 * lib/strtoul.c: New file, from gnulib.
12892 This fixes a porting bug reported by Peter Klein in
12893 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
12895 2002-11-30 Paul Eggert <eggert@twinsun.com>
12897 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
12898 and put only a forward declaration in the prologue. This is for
12899 consistency with the other scanner helper functions.
12901 Type clashes now generate warnings, not errors, since it
12902 appears that POSIX may allow some grammars with type clashes.
12903 * src/reader.c (grammar_current_rule_check): Warn about
12904 type clashes instead of complaining.
12905 * tests/input.at (Type Clashes): Expect warnings, not complaints.
12907 Add Yacc library, since POSIX requires it.
12908 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
12909 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
12910 * lib/main.c, lib/yyerror.c: New files.
12912 gram_error can be static; it need not be extern.
12913 * src/reader.h (gram_error): Remove decl.
12914 * src/parse-gram.y (gram_error): Now static. Add static decl.
12915 (print_token_value): Omit parameter names from forward decl,
12918 2002-11-29 Paul Eggert <eggert@twinsun.com>
12920 * doc/bison.texinfo: Emphasize that yylex and yyerror must
12921 be declared before being used. E.g., one should typically
12922 declare them in the prologue. Use GNU coding style in examples.
12923 Put "const" consistently after the type it modifies. Mention
12924 that C99 supports "inline". Mention that yyerror traditionally
12927 %parse-param and %lex-param now take just one argument, the
12928 declaration; the argument name is deduced from the declaration.
12930 * doc/bison.texinfo (Parser Function, Pure Calling, Error
12931 Reporting, Table of Symbols): Document this.
12932 * src/parse-gram.y (add_param): New function.
12934 (declaration): Implement new rule for %parse-param and %lex-param.
12935 * src/scan-gram.l: "," now elicits a warning, rather than being
12936 a token; this is more compatible with byacc.
12937 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
12939 2002-11-27 Paul Eggert <eggert@twinsun.com>
12941 Rename identifiers to avoid real and potential collisions.
12943 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
12944 to avoid collision with lex macro described by Bruce Lilly in
12945 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12946 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
12947 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
12948 * src/parse-gram.y (print_token_value): Renamed from yyprint.
12950 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
12951 The name "yycontrol" violates the name space rules, and this stuff
12952 wasn't being used anyway.
12953 (input): Remove action; this stuff wasn't being used.
12954 (gram_error): Rename local variable yylloc -> loc.
12955 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
12956 (YY_DECL): Don't use "yy" at start of local variables.
12957 All uses changed, e.g., yylloc -> loc.
12958 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
12959 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
12960 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
12961 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
12963 * src/parse-gram.y (gram_error): loc is now const *.
12964 * src/reader.h (gram_error): Likewise.
12966 2002-11-24 Paul Eggert <eggert@twinsun.com>
12970 * tests/actions.at (Actions after errors): Use an output format
12971 more similar to that of the Printers and Destructors test.
12972 Test the position of the ';' token too.
12973 (Printers and Destructors): Likewise.
12974 (Printers and Destructors: %glr-parser): Remove for now, to avoid
12975 unnecessarily alarming people when the test fails.
12977 * data/yacc.c (yyerrlab1): Move this label down, so that the
12978 parser does not discard the lookahead token if the user code
12979 invokes YYERROR. This change is required for POSIX conformance.
12981 * lib/error.c: Sync with gnulib.
12983 2002-11-22 Paul Eggert <eggert@twinsun.com>
12985 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
12986 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
12987 * lib/xmalloc.c: Likewise.
12989 2002-11-20 Paul Eggert <eggert@twinsun.com>
12991 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
12993 2002-11-20 Paul Eggert <eggert@twinsun.com>
12995 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
12996 should use `if (! x) abort ();' rather than `assert (x);', and
12997 anyway it's one less thing to worry about configuring.
12999 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
13000 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
13001 and replace all instances of assert with abort.
13002 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
13003 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
13005 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
13006 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
13007 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
13008 hash_find_entry, hash_rehash, hash_insert): Likewise.
13009 * src/conflicts.c (resolve_sr_conflict): Likewise.
13010 * src/lalr.c (set_goto_map, map_goto): Likewise.
13011 * src/nullable.c (nullable_compute): Likewise.
13012 * src/output.c (prepare_rules, token_definitions_output): Likewise.
13013 * src/reader.c (packgram, reader): Likewise.
13014 * src/state.c (state_new, state_free, state_transitions_set,
13015 state_reduction_find): Likewise.
13016 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
13017 symbol_pack): Likewise.
13018 * src/tables.c (conflict_row, pack_vector): Likewise.
13019 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
13020 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
13021 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
13022 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
13024 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
13025 (ARGMATCH_CONSTRAINT): New macro.
13026 (ARGMATCH_ASSERT): Use it.
13028 * src/system.h (verify): New macro.
13029 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
13030 rather than assert.
13031 * src/tables.c (tables_generate): Likewise.
13033 * src/struniq.c (struniq_assert): Now returns void, and aborts
13034 if the assertion is false.
13035 (struniq_assert_p): Remove.
13036 * src/struniq.h: Likewise.
13038 2002-11-18 Paul Eggert <eggert@twinsun.com>
13040 * data/glr.c (yygetLRActions): Replace `yyindex' with
13041 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
13042 This fixes the regression with Sun ONE Studio 7 cc that I reported in
13043 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
13045 2002-11-18 Akim Demaille <akim@epita.fr>
13047 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
13049 From Tim Van Holder.
13051 2002-11-17 Paul Eggert <eggert@twinsun.com>
13053 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
13054 to "SyntaxError" for consistency with my 2002-11-15 change.
13056 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
13057 not define to {}, since this breaks the common use of `YYDPRINTF
13058 ((...));' if a single statement is desired (e.g. before `else').
13059 Work around GCC warnings by surrounding corresponding calls with
13061 (yyhasResolvedValue): Remove unused function.
13062 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
13064 (yyreportSyntaxError): Renamed from yyreportParseError.
13065 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
13067 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
13068 extern when possible. Remove unused initializations.
13070 2002-11-16 Akim Demaille <akim@epita.fr>
13072 Augment the similarity between GLR and LALR traces.
13074 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
13075 (YY_REDUCE_PRINT): New.
13076 (yyparse): Use them.
13077 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
13079 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
13080 state reached after the reduction/recovery, since...
13081 (yyparse, yyprocessOneStack): Report the state we are entering in.
13083 2002-11-16 Akim Demaille <akim@epita.fr>
13085 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
13086 Add support for --trace=skeleton.
13087 * src/scan-skel.l: %option debug.
13088 Scan strings of non-@ or \n instead of character by character.
13089 (scan_skel): Handle trace_skeleton.
13091 (@output_parser_name@, @output_header_name@): ``Restore'' their
13092 support (used to be M4 macros).
13093 * data/yacc.c: Quote larger chunks, a la glr.c.
13094 * data/lalr1.cc: Likewise.
13095 The header guards are no longer available, so use some other
13096 string than `YYLSP_NEEDED'.
13098 2002-11-16 Akim Demaille <akim@epita.fr>
13100 Make the ``Printers and Destructors'' test more verbose, taking
13101 `yacc.c''s behavior as (possibly wrong) reference.
13103 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
13104 instead of fprint on stdout.
13105 Set and report the last_line of the symbols.
13106 Consistently display values and locations.
13108 2002-11-16 Paul Eggert <eggert@twinsun.com>
13110 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
13112 2002-11-15 Paul Eggert <eggert@twinsun.com>
13114 * tests/actions.at (Actions after errors): New test case.
13116 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
13117 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
13118 tests/action.at, tests/calc.at, tests/conflicts.at,
13119 tests/cxx-type.at, tests/regression.at:
13120 "parse error" -> "syntax error" for POSIX compatibility.
13121 "parsing stack overflow..." -> "parser stack overflow" so
13122 that code matches Bison documentation.
13124 2002-11-15 Akim Demaille <akim@epita.fr>
13126 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
13127 take two BRACED_CODE, not two string_content.
13128 Free the scanner's obstack when we are done.
13129 (code_content): New.
13130 * tests/calc.at: Adjust.
13131 * doc/bison.texinfo: Adjust.
13132 Also, make sure to include the `,' for these declarations.
13134 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
13136 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
13137 definition; avoids potential autoreconf problems.
13139 2002-11-15 Akim Demaille <akim@epita.fr>
13141 Always check the value returned by yyparse.
13143 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
13144 returned by yyparse.
13145 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
13147 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
13148 returned by yyparse.
13150 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13152 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
13155 2002-11-14 Paul Eggert <eggert@twinsun.com>
13157 * src/output.c (output_skeleton): Call xfopen instead of
13158 duplicating xfopen's body.
13160 Fix bugs reported by Nelson H. F. Beebe in
13161 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
13163 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
13164 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
13165 Group compiler. Instead, use "$CC -E bar.c". Include the .h
13166 file twice in the grammar, as an extra check.
13168 * tests/input.at (Torturing the Scanner): Surround the
13169 backslash-newline tests with "#if 0", to make it less likely that
13170 we'll run into compiler bugs. Bring back solitary \ inside
13171 comment, but add a closing comment to work around HP C bug. Don't
13172 test backslash-newline in C character constant.
13174 2002-11-14 Akim Demaille <akim@epita.fr>
13176 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
13177 status of the compiler.
13178 Calling `exit 1' is no longer needed.
13179 Reported by Nelson H. F. Beebe.
13181 2002-11-14 Akim Demaille <akim@epita.fr>
13183 * tests/atlocal.in (CPPFLAGS): We have config.h.
13184 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
13186 * tests/actions.at, tests/calc.at, tests/conflicts.at,
13187 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
13188 * tests/regression.at, tests/torture.at: Use them for all the
13189 grammars that are to be compiled.
13190 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
13191 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
13192 * doc/bison.texinfo (GLR Parsers): Document `inline'.
13194 2002-11-14 Akim Demaille <akim@epita.fr>
13196 * doc/bison.texinfo: Various formatting changes (alignments in
13197 samples, additional @group/@end group, GCS in samples.
13198 Use @deffn instead of simple @table to define the directives,
13199 macros, variables etc.
13201 2002-11-13 Paul Eggert <eggert@twinsun.com>
13203 Fix some bugs reported by Albert Chin-A-Young in
13204 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
13206 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
13207 -o c"; the HP C compiler chatters during compilation.
13208 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
13209 * tests/headers.at (export YYLTYPE): Likewise.
13211 * tests/input.at (Torturing the Scanner): Remove lines containing
13212 solitary backslashes, as they tickle a bug in the HP C compiler.
13214 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
13215 comments, since they're not portable. Use GNU coding style.
13217 2002-11-13 Akim Demaille <akim@epita.fr>
13219 * data/yacc.c: Leave bigger chunks of quoted text.
13220 (YYDSYMPRINTF): New.
13221 Use it to report symbol activities.
13222 * data/glr.c (YYDSYMPRINTF): New.
13225 2002-11-12 Paul Eggert <eggert@twinsun.com>
13229 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
13230 (yyglrReduce): Return yyok, not 0.
13231 This should avoid the enumerated-type warnings reported
13232 by Nelson H. F. Beebe in
13233 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
13235 * lib/bbitset.h (BITSET_INLINE): Remove.
13236 * lib/bitset.h [! BITSET_INLINE]: Remove.
13237 (bitset_set, bitset_reset, bitset_test): Rename local vars
13238 to avoid shadowing warnings by GCC.
13240 * data/glr.c (inline): Remove #define. It's the user's
13241 responsibility to #define it away, just like 'const'.
13242 This fixes one of the bugs reported by Nelson H. F. Beebe in
13243 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
13245 * Makefile.maint (po-check): Scan .l and .y files instead of the
13246 .c and the .h files that they generate. This fixes the bug
13247 reported by Tim Van Holder in:
13248 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
13249 Look for N_ as well as for _. Try to avoid matching #define for
13251 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
13252 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
13253 * src/scan-gram.l: Revamp regular expressions so that " and '
13254 do not confuse xgettext.
13256 * src/struniq.h (struniq_new): Do not declare the return type
13257 to be 'const'; this violates the C standard.
13258 * src/struniq.c (struniq_new): Likewise.
13260 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
13262 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
13263 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
13266 2002-11-12 Akim Demaille <akim@epita.fr>
13268 * Makefile.maint: Sync with Autoconf:
13269 (local_updates): New.
13271 2002-11-12 Akim Demaille <akim@epita.fr>
13273 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
13275 2002-11-12 Akim Demaille <akim@epita.fr>
13277 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the

13406 Revamp to fix many (but not all) of the C- and M4-related quoting
13407 problems. Among other things, this fixes the Bison bug reported
13408 by Jan Hubicka when processing the Bash grammar; see:
13409 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
13411 Use new @ escapes consistently. Represent brackets with @{ and @}
13412 rather than @<:@ and @:>@, since this works a bit better with dumb
13413 editors like vi. Represent @ with @@, since @ is now consistently
13414 an escape. Use @oline@ and @ofile@ rather than __oline__ and
13415 __ofile__, to avoid unexpected expansions. Similarly, use @output
13416 rather than #output.
13418 * data/c.m4 (b4_copyright): Omit file name from comment, since
13419 the file name could contain "*/".
13420 (b4_synclines_flag): Don't quote the 2nd argument; it should already
13421 be quoted. All uses changed.
13423 * data/glr.c: Use new @ escapes consistently.
13424 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
13425 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
13426 Remove, since they couldn't handle arbitrary characters in file
13428 * data/lalr1.cc: Likewise.
13429 * data/yacc.c: Likewise.
13431 * src/files.c (output_infix): Remove; all uses removed.
13432 * src/files.h: Likewise.
13434 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
13435 mishandled funny characters in file names, and anyway it isn't
13437 * data/yacc.c: Likewise.
13438 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
13440 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
13441 * data/yacc.c: Likewise.
13443 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
13445 (muscle_init): Quote filename as a C string.

13447 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
13448 * src/output.c (escaped_file_name_output): New function.
13449 (prepare_symbols): Quote tokens for M4.
13450 (prepare): Don't insert output_infix, output_prefix,
13451 output_parser_name, output_header_name; this is now down by scan-skel.
13452 Insert skeleton as a C string.
13454 * src/output.c (user_actions_output, symbol_destructors_output,
13455 symbol_printers_output): Quote filenames for C and M4.
13456 * src/reader.c (prologue_augment, epilogue_set): Likewise.
13458 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
13459 escapes other than \\ and \'; this simplifies the code.
13460 (<SC_STRING>): Likewise, for \\ and \".
13461 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
13462 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
13463 Use new escapes @{ and @} for [ and ].
13465 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
13466 them with auto vars.
13467 Switch to new escape scheme, where @ is the escape character uniformly.
13468 Abort if a stray escape character is found. Avoid unbounded input
13469 buffer when parsing non-escaped text.
13471 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
13472 __oline__, #output, $@, and @{ do not have unintended meanings.
13474 2002-11-09 Paul Eggert <eggert@twinsun.com>
13476 Fix the test failure due to GCC warnings described in
13477 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
13478 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
13479 evaluate to 0 if it's impossible for NINF to be in the respective
13481 (yygetLRActions, yyrecoverParseError): Use them.
13483 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
13484 counted in the token inserted at end of file. Now takes
13485 location_t *, not location_t, so that the location can be
13486 adjusted. All uses changed.
13488 * tests/regression.at (Invalid inputs): Adjust wording in
13489 diagnostic to match the new behavior.
13491 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
13492 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
13493 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
13494 abort ();'. This reduces the runtime of the "Many lookaheads"
13495 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
13498 2002-11-07 Paul Eggert <eggert@twinsun.com>
13500 * src/parse-gram.y (CHARACTER): Remove unused token.
13503 * src/scan-gram.l: Remove stack option. We no longer use the
13504 stack, since the stack was never deeper than 1; instead, use the
13505 new auto var c_context to record the stacked value.
13507 Remove nounput option. At an unexpected end of file, we now unput
13508 the minimal input necessary to end cleanly; this simplifies the
13511 Avoid unbounded token sizes where this is easy.
13513 (unexpected_end_of_file): New function.
13514 Use it to systematize the error message on unexpected EOF.
13515 (last-string): Now auto, not static.

13519 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
13520 not the (never otherwised-used) CHARACTER.
13522 2002-11-07 Akim Demaille <akim@epita.fr>

13745 * src/system.h (errno): Remove declaration, as we are now
13746 assuming C89 or better, and C89 guarantees errno.
13748 2002-10-30 Paul Eggert <eggert@twinsun.com>
13750 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
13751 Check for close failures.
13752 * src/files.h (xfclose): Return void, not int, since it always
13754 * src/files.c (xfclose): Likewise. Report I/O error if ferror
13756 * src/output.c (output_skeleton): Use xfclose rather than fclose
13757 and ferror. xfclose now checks ferror.
13759 * data/glr.c (YYLEFTMOST_STATE): Remove.
13760 (yyreportTree): Use a stack-based leftmost state. This avoids
13761 our continuing battles with bogus warnings about initializers.
13763 2002-10-30 Akim Demaille <akim@epita.fr>
13765 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
13768 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13770 * tests/glr-regr1.at: New test for reported regressions.
13771 * tests/testsuite.at: Add glr-regr1.at test.
13772 * tests/Makefile.am: Add glr-regr1.at test.
13774 2002-10-24 Paul Eggert <eggert@twinsun.com>
13778 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
13779 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
13780 we use malloc. Don't assume 'A' through 'Z' are contiguous.
13781 Don't assume strdup exists; POSIX says its an XSI extension.
13782 Check for buffer overflow on input.
13784 2002-10-24 Akim Demaille <akim@epita.fr>
13786 * src/output.c (output_skeleton): Don't disable M4sugar comments
13787 too soon: it results in comments being expanded.
13788 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
13791 2002-10-24 Akim Demaille <akim@epita.fr>
13793 * data/yacc.c (m4_int_type): New.
13794 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
13795 char' as only yacc.c wants K&R portability.
13796 * data/glr.c (yysigned_char): Remove.
13797 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
13798 Reported by Quoc Peyrot.
13800 2002-10-23 Paul Eggert <eggert@twinsun.com>
13802 * src/main.c (main): With --trace=time, report times even if a
13803 non-fatal error occurs. Formerly, the times were reported in some
13804 such cases but not in others.
13805 * src/reader.c (reader): Just return if a complaint has been issued,
13806 instead of exiting, so that 'main' can report times.
13808 2002-10-22 Akim Demaille <akim@epita.fr>
13810 * src/system.h: Include sys/types.
13811 Reported by Bert Deknuydt.
13813 2002-10-23 Paul Eggert <eggert@twinsun.com>
13815 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
13816 Suggested by Art Haas.
13818 2002-10-22 Paul Eggert <eggert@twinsun.com>
13820 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
13821 decl; not needed any more.
13822 * src/main.c (main): Use return to exit, undoing yesterday's change.
13823 The last OS that we could find where this wouldn't work is
13824 SunOS 3.5, and that's too old to worry about now.
13826 * data/glr.c (struct yyltype): Define members even when not
13827 doing locations. This is more consistent with yacc.c, and it
13828 works around the following bug reports:
13829 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
13830 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
13832 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
13833 @acronym consistently. Standardize on "Yacc" instead of "YACC",
13834 "Algol" instead of "ALGOL". Give a bit more history about BNF.
13836 2002-10-22 Akim Demaille <akim@epita.fr>
13838 * data/README: New.
13840 2002-10-21 Paul Eggert <eggert@twinsun.com>
13842 Be consistent about 'bool'; the old code used an enum in one
13843 module and an int in another, and this violates the C standard.
13844 * m4/stdbool.m4: New file, from coreutils 4.5.3.
13845 * configure.ac (AC_HEADER_STDBOOL): Add.
13846 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
13847 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
13848 * src/symtab.c (hash_compare_symbol_t): Likewise.
13849 * src/system.h (bool, false, true): Use a definition consistent
13850 with ../lib/hash.c. All uses changed.
13852 * src/complain.c (warning_issued): Renamed from warn_message_count,
13853 so that we needn't worry about integer overflow (!).
13854 Now of type bool. All uses changed.
13855 (complaint_issued): Renamed from complain_message_count; likewise.
13857 * src/main.c (main): Use exit to exit with failure.
13859 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
13860 rather than 1 and 0.
13861 * src/main.c (main): Likewise.
13862 * src/getargs.c (getargs): Likewise.
13863 * src/reader.c (reader): Likewise.
13865 * src/getarg.c (getargs): Remove duplicate code for
13866 "Try `bison --help'".
13868 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
13869 What was that "2" for?
13871 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
13872 * src/getargs.c (usage): Likewise.
13874 * src/getargs.c (getargs): When there are too few operands, report
13875 the last one. When there are too many, report the first extra
13876 one. This is how diffutils does it.
13878 2002-10-20 Paul Eggert <eggert@twinsun.com>
13880 Remove K&R vestiges.
13881 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
13882 * src/complain.c (VA_START): Remove. Assume prototypes.
13883 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
13884 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
13885 fatal): Assume prototypes.
13886 * src/complain.h: Assume prototypes.
13887 * src/system.h (PARAMS): Remove.
13888 Include <limits.h> unconditionally, since it's guaranteeed even
13889 for a freestanding C89 compiler.
13890 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
13891 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
13893 2002-10-20 Akim Demaille <akim@epita.fr>
13895 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
13896 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
13897 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
13898 (yyresolveStates, yyresolveAction, yyresolveStack)
13899 (yyprocessOneStack): Use them.
13900 (yy_reduce_print): New.
13901 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
13903 2002-10-20 Akim Demaille <akim@epita.fr>
13905 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
13906 arguments and output `void'.
13907 (b4_c_function): Rename as...
13908 (b4_c_function_def): this.
13909 (b4_c_function_decl, b4_c_ansi_function_def)
13910 (b4_c_ansi_function_decl): New.
13911 Change the interpretation of the arguments: before `int, foo', now
13913 * data/yacc.c (yyparse): Prototype and define thanks to these.
13914 Adjust b4_c_function_def uses.
13915 * data/glr.c (yyparse): Likewise, but ANSI only.
13917 2002-10-20 Akim Demaille <akim@epita.fr>
13919 * src/output.c (prepare): Move the definition of `tokens_number',
13920 `nterms_number', `undef_token_number', `user_token_number_max'
13922 (prepare_tokens): Here.
13923 (prepare_tokens): Rename as...
13924 (prepare_symbols): this.
13925 (prepare): Move the definition of `rules_number' to...
13926 (prepare_rules): here.
13927 (prepare): Move the definition of `last', `final_state_number',
13928 `states_number' to...
13929 (prepare_states): here.
13930 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
13932 2002-10-20 Akim Demaille <akim@epita.fr>
13934 * src/tables.h, src/tables.c, src/output.c: Comment changes.
13936 2002-10-20 Akim Demaille <akim@epita.fr>
13938 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
13941 2002-10-20 Akim Demaille <akim@epita.fr>
13943 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
13944 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
13946 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
13948 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
13949 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
13952 2002-10-19 Paul Eggert <eggert@twinsun.com>
13954 Do not create a temporary file, as that involves security and
13955 cleanup headaches. Instead, use a pair of pipes.
13956 Derived from a suggestion by Florian Krohm.
13957 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
13958 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
13959 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
13960 (BISON_PREREQ_SUBPIPE): Add.
13961 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
13962 Add subpipe.h, subpipe.c.
13963 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
13964 * po/POTFILES.in: Add lib/subpipe.c.
13965 * src/output.c: Include "subpipe.h".
13966 (m4_invoke): Remove decl.
13967 (scan_skel): New decl.
13968 (output_skeleton): Use pipe rather than temporary file for m4 input.
13969 Check that m4sugar.m4 is readable, to avoid deadlock.
13970 Check for pipe I/O error.
13971 * src/scan-skel.l (readpipe): Remove decl.
13972 (scan_skel): New function, to be used in place of m4_invoke.
13973 Read from stream rather than file.
13975 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
13976 float, as this generates a warning on Solaris 8 + GCC 3.2 with
13977 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
13978 this generates a more-accurate value anyway.
13980 * lib/timevar.c (timervar_accumulate): Rename locals to
13981 avoid confusion with similarly-named more-global.
13982 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
13984 * src/output.c (prepare): Use xstrdup to convert char const *
13985 to char *, to avoid GCC warning.
13987 2002-10-19 Akim Demaille <akim@epita.fr>
13989 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
13990 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
13991 Use them to have `calc.y' ready for %pure-parser.
13992 * data/yacc.c (YYLEX): Pass a yylex return type to
13993 b4_c_function_call.
13995 2002-10-19 Akim Demaille <akim@epita.fr>
13997 Prototype support of %lex-param and %parse-param.
13999 * src/parse-gram.y: Add the definition of the %lex-param and
14000 %parse-param tokens, plus their rules.
14001 Drop the `_' version of %glr-parser.
14003 * src/scan-gram.l (INITIAL): Scan them.
14004 * src/muscle_tab.c: Comment changes.
14005 (muscle_insert, muscle_find): Rename `pair' as `probe'.
14006 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
14007 (muscle_entry_s): The `value' member is no longer const.
14008 Adjust all dependencies.
14009 * src/muscle_tab.c (muscle_init): Adjust: use
14010 MUSCLE_INSERT_STRING.
14011 Initialize the obstack earlier.
14012 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
14013 (muscle_pair_list_grow): New.
14014 * data/c.m4 (b4_c_function_call, b4_c_args): New.
14015 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
14016 * tests/calc.at: Use %locations, not --locations.
14017 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
14019 2002-10-19 Akim Demaille <akim@epita.fr>
14021 * src/getargs.c (usage): Take status as argument and exit
14023 Report the traditional `Try ... --help' message when status != 0.
14024 (usage, version): Don't take a FILE * as arg, it is pointless.
14025 (getargs): When there is an incorrect number of arguments, make it
14026 an error, and report it GNUlically thanks to `usage ()'.
14028 2002-10-18 Paul Eggert <eggert@twinsun.com>
14030 * data/glr.c (yyreportParseError): Don't assume that sprintf
14031 yields the length of the printed string, as this is not true
14032 on SunOS 4.1.4. Reported by Peter Klein.
14034 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
14035 * tests/conflicts.at (%nonassoc and eof): Likewise.
14036 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
14038 2002-10-17 Akim Demaille <akim@epita.fr>
14040 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
14041 * src/getargs.c (trace_types, trace_args): Adjust.
14042 * src/reader.c (grammar_current_rule_prec_set)
14043 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
14044 Standardize error messages.
14045 And s/@prec/%prec/!
14046 (reader): Use trace_flag to enable scanner/parser debugging,
14047 instead of an adhoc scheme.
14048 * src/scan-gram.l: Remove trailing debugging code.
14050 2002-10-16 Paul Eggert <eggert@twinsun.com>
14052 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
14055 * NEWS: Officially drop support for building Bison with K&R C,
14056 since it didn't work anyway and it's not worth worrying about.
14057 * Makefile.maint (wget_files): Remove ansi2knr.c.
14058 (ansi2knr.c-url_prefix): Remove.
14059 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
14060 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
14061 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
14063 2002-10-15 Paul Eggert <eggert@twinsun.com>
14065 Stop using the "enum_" trick for K&R-style function definitions;
14066 it confused me, and I was the author! Instead, assume that people
14067 who want to use K&R C compilers (when using these modules in GCC,
14068 perhaps?) will run ansi2knr.
14070 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
14071 All uses of "enum_" changed to "enum ".
14072 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

14083 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
14084 Use function prototypes; this removes the need for declaring
14085 static functions simply to provide their prototypes.

14160 tests/cxx-type.at, tests/headers.at, tests/input.at,
14161 tests/regression.at, tests/synclines.at, tests/torture.at:
14162 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
14163 so that the tests still work even if POSIXLY_CORRECT is set.
14164 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
14166 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
14167 for portability to K&R hosts. Fix typo: signed char is guaranteed
14168 only to 127, not to 128.
14169 * data/glr.c (yysigned_char): New type.
14170 * data/yacc.c (yysigned_char): Likewise.
14171 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
14173 2002-10-13 Paul Eggert <eggert@twinsun.com>
14175 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
14176 true due to limited range of data type" warning from GCC.
14178 * data/c.m4 (b4_token_defines): Protect against double-inclusion
14179 by wrapping enum yytokentype's definition inside #ifndef
14180 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
14182 2002-10-13 Akim Demaille <akim@epita.fr>
14184 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
14185 Un yy- yyrhs to avoid the name clash with the global YYRHS.
14187 2002-10-13 Akim Demaille <akim@epita.fr>
14189 * Makefile.maint: Update from Autoconf 2.54.
14190 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
14192 2002-10-13 Akim Demaille <akim@epita.fr>
14194 * src/print.c (print_state): Separate the list of solved conflicts
14195 from the other items.
14196 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
14198 2002-10-13 Akim Demaille <akim@epita.fr>
14200 Let nondeterministic skeletons be usable with deterministic
14203 With the patch, GAWK compiled by GCC without -O2 passes its test
14204 suite using a GLR parser driven by LALR tables. It fails with -O2
14205 because `struct stat' gives two different answers on my machine:
14206 88 (definition of an auto var) and later 96 (memset on this var).
14207 Hence the stack is badly corrumpted. The headers inclusion is to
14208 blame: if I move the awk.h inclusion before GLR's system header
14209 inclusion, the two struct stat have the same size.
14211 * src/tables.c (pack_table): Always create conflict_table.
14212 (token_actions): Always create conflict_list.
14213 * data/glr.c (YYFLAG): Remove, unused.
14215 2002-10-13 Akim Demaille <akim@epita.fr>
14217 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
14219 (VALGRIND, GXX): New.
14220 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
14221 * tests/bison.in: Run $PREBISON a pre-command.
14222 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
14223 (maintainer-check-g++): New.
14224 * Makefile.am (maintainer-check): New.
14226 2002-10-13 Akim Demaille <akim@epita.fr>
14228 * data/glr.c: Formatting changes.
14229 Tweak some trace messages to match yacc.c's.
14231 2002-10-13 Akim Demaille <akim@epita.fr>
14233 GLR parsers sometimes raise parse errors instead of performing the
14235 Reported by Charles-Henry de Boysson.
14237 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
14238 check the length of the traces when %glr.
14239 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
14241 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
14243 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
14244 (yyltype): Remove the yy prefix from the member names.
14245 (yytable): Complete its comment.
14246 (yygetLRActions): Map error action number from YYTABLE from
14248 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
14249 (which was a bug: it should have been YYTABEL_NINF, and yet it was
14250 not satisfying as we could compare an YYACTION computed from
14251 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
14252 only value for error actions.
14253 (yyreportParseError): In verbose parse error messages, don't issue
14254 `error' in the list of expected tokens.
14255 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
14256 next action to perform to match glr.c's decoding.
14257 (yytable): Complete its comment.

14261 Fix problem reported by Henrik Grubbstroem in
14262 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
14263 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
14264 because the Bison parser reads the second action before reducing
14266 * src/scan-gram.l (rule_length): New static var.
14267 Use it to keep track of the rule length in the scanner, since
14268 we can't expect the parser to be in lock-step sync with the scanner.
14269 (handle_action_dollar, handle_action_at): Use this var.
14270 * tests/actions.at (Exotic Dollars): Test for the problem.
14272 2002-10-12 Paul Eggert <eggert@twinsun.com>
14274 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
14275 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
14276 Include <sys/time.h> when checking for clock_t and struct tms.
14277 Use same include order as source.
14278 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
14279 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
14281 * lib/timevar.c: Update copyright date and clarify comments.
14282 (get_time) [IN_GCC]: Keep the GCC version for reference.
14284 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
14285 GCC version as of today, then merge Bison's changes.
14286 Change "GCC" to "Bison" in copyright notice. timevar.def's
14287 author is Akim, so change that too.
14289 * src/reader.c (grammar_current_rule_check):
14290 Don't worry about the default action if $$ is untyped.
14291 Prevents bogus warnings reported by Jim Gifford in

14295 * data/glr.c, data/lalr1.cc, data/yacc.c:
14296 Output token definitions before the first part of user declarations.

14320 Portability fixes for bitsets; this also avoids several GCC
14323 * lib/abitset.c: Include <stddef.h>, for offsetof.
14324 * lib/lbitset.c: Likewise.
14326 * lib/abitset.c (abitset_bytes): Return a size that is aligned
14327 properly for vectors of objects. Do not assume that adding a
14328 header size to a multiple of a word size yields a value that is
14329 properly aligned for the whole union.
14330 * lib/bitsetv.c (bitsetv_alloc): Likewise.
14332 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
14333 unique names for structures.

14343 abitset_or_and_cmp, abitset_copy): Supply prototype decls,

14365 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
14366 All instances of parameters of type enum bitset_opts are now of
14367 type enum_bitset_opts, to conform to the C Standard, and similarly
14368 for enum_bitset_type.
14369 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
14370 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
14372 Do not use "struct bitset_struct" to mean different things in
14373 different modules. Not only is this confusing, it violates
14374 the C Standard, which requires that structure types in different
14375 modules must be compatible if one is to be passed to the other.
14376 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
14377 All instances of "struct bitset_struct *" replaced with "bitset".
14378 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
14379 (union bitset_union, struct abitset_struct, struct ebitset_struct,
14380 struct lbitset_struct, struct bitset_stats_struct): New types.

14388 bitset_struct): Remove.
14389 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
14392 Do not call a function of type T using a call that assumes the
14393 function is of a different type U. Standard C requires that a
14394 function must be called with a type that is compatible with its

14417 Use offsetof, for simplicity.
14419 2002-10-06 Paul Eggert <eggert@twinsun.com>
14421 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
14422 the same width as int. This reapplies a hunk of the 2002-08-12 patch
14423 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
14424 which was inadvertently undone by the 2002-09-30 patch.

14426 the same width as int.

14432 * configure.ac (AC_INIT), NEWS: Increment version number.
14434 * doc/bison.texinfo: Minor spelling, grammar, and white space
14436 (Symbols): Mention that any negative value returned from yylex
14437 signifies end-of-input. Warn about negative chars. Mention
14438 the portable Standard C character set.
14440 The GNU coding standard says CFLAGS and YFLAGS are reserved
14441 for the installer to set.
14442 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
14443 * src/Makefile.am (AM_CFLAGS): Likewise.
14444 (AM_YFLAGS): Renamed from YFLAGS.
14446 Fix some MAX and MIN problems.

14449 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
14450 * src/reader.c (reader): Use it.
14452 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
14453 POSIX 1003.1-2001 has removed fgrep.
14455 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>

14528 to BITSET_WINDEX_MAX.

14630 2002-09-06 Paul Eggert <eggert@twinsun.com>
14632 * doc/bison.texinfo (Conditions): Make explicit that the GPL
14633 exception applies only to yacc.c. This is a modification of a
14634 patch originally suggested by Akim Demaille.

14686 as int, and similarly for yyposn and YYINDEX.

14728 PROTOTYPES to check for prototypes, and "defined __STDC__" to

14734 (bitset_test): Now returns int, not unsigned long.

14783 as it mishandles negative chars and it may not work as expected
14784 outside the C locale.
14786 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
14787 this is a GCC extension and is not portable to other compilers.

14794 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
14797 * tests/regression.at: Do not use 'cc -c input.c -o input';
14798 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
14800 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
14801 exit status as failure, not just exit status 1. Sun C exits
14802 with status 2 sometimes.

14965 Report rules which are never reduced by the parser: those hidden

14969 different: save its reduction (accept) instead of having a state
14970 without any action (no shift or goto, no reduce).
14971 Note: the final state is now a ``regular'' state, i.e., the
14972 parsers now contain `reduce 0' as default reduction.
14973 Nevertheless, since they decide to `accept' when yystate =
14974 final_state, they still will not reduce rule 0.

15020 yycontrol without making too strong assumptions on the parser
15022 * src/output.c (prepare_tokens): Use the real 0th value of
15023 token_translations instead of `0'.
15024 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
15026 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
15027 for the time being: %locations ought to provide it to yyerror.
15029 2002-07-25 Akim Demaille <akim@epita.fr>
15031 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
15032 * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./.
15033 * tests/regression.at (Web2c Actions): Adjust.
15035 2002-07-25 Akim Demaille <akim@epita.fr>
15037 Stop storing rules from 1 to nrules + 1.

15040 * src/nullable.c, src/output.c, src/print.c, src/reader.c
15041 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].

16728 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
16729 full stderr, and strip it according to the bison options, instead

16733 Add an invocation exercising the error token.
16734 Add an invocation demonstrating a stupid error message.
16735 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

17497 2002-01-20 Marc Autret <marc@gnu.org>
17499 * tests/output.at: New test.
17500 * src/files.c (compute_base_names): Don't map extensions when
17501 the YACC flag is set, use defaults.
17502 Reported by Evgeny Stambulchik.
17504 2002-01-20 Marc Autret <marc@gnu.org>
17506 * src/system.h: Need to define __attribute__ away for non-GCC
17507 compilers as well (i.e., the vendor C compiler).
17508 Suggested by Albert Chin-A-Young.
17510 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
17512 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
17513 canonical definition.
17514 * src/system.h: Use the canonical definition for PARAMS (avoids
17515 a conflict with the macro from lib/hash.h).
17517 2002-01-11 Akim Demaille <akim@epita.fr>
17519 * configure.in: Use AC_FUNC_STRNLEN.
17520 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
17522 2002-01-09 Akim Demaille <akim@epita.fr>
17524 * src/files.c, src/files.h (output_infix): New.
17525 (tab_extension): Remove.
17526 (compute_base_names): Compute the former, drop the latter.
17527 * src/output.c (prepare): Insert the muscles `output-infix', and
17529 * src/parse-skel.y (string, string.1): New.
17530 (section.header): Use it.
17531 (section.yacc): Remove.
17532 (prefix): Remove too.
17533 * src/scan-skel.l: Adjust.
17534 * src/bison.simple, src/bison.hairy: Adjust.
17536 2002-01-09 Akim Demaille <akim@epita.fr>
17538 * configure.in (WERROR_CFLAGS): Compute it.
17539 * src/Makefile.am (CFLAGS): Pass it.
17540 * tests/atlocal.in (CFLAGS): Idem.
17541 * src/files.c: Fix a few warnings.
17542 (get_extension_index): Remove, unused.
17544 2002-01-08 Akim Demaille <akim@epita.fr>
17546 * src/getargs.c (AS_FILE_NAME): New.
17547 (getargs): Use it to convert DOSish file names.
17548 * src/files.c (base_name): Rename as full_base_name to avoid
17549 clashes with `base_name ()'.
17550 (filename_split): New.
17551 (compute_base_names): N-th rewrite, using filename_split.
17553 2002-01-08 Akim Demaille <akim@epita.fr>
17555 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
17556 New, stolen from the Fileutils 4.1.
17557 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
17558 * configure.in: Check for the presence of memrchr, and of its
17561 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
17563 * lib/hash.h (__P): Added definition for this macro.
17564 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
17565 BUILT_SOURCES, to ensure they are generated first.
17566 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
17567 %error-verbose to allow bootstrapping with bison 1.30x.
17569 2002-01-06 Akim Demaille <akim@epita.fr>
17571 * src/reader.c (parse_braces): Don't fetch the next char, the
17572 convention is to fetch on entry.
17573 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
17574 'switch' without a following semicolon.
17575 * tests/regression.at (braces parsing): New.
17577 2002-01-06 Akim Demaille <akim@epita.fr>
17579 Bison is dead wrong in its RR conflict reports.
17581 * tests/torture.at (GNU Cim Grammar): New.
17582 * src/conflicts.c (count_rr_conflicts): Fix.
17584 2002-01-06 Akim Demaille <akim@epita.fr>
17586 Creating package.m4 from configure.ac causes too many problems.
17588 * tests/Makefile.am (package.m4): Create it by hand,
17589 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
17591 2002-01-06 Akim Demaille <akim@epita.fr>
17593 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
17596 2002-01-04 Paul Eggert <eggert@twinsun.com>
17598 * doc/bison.texinfo (Debugging):
17599 Remove YYSTDERR; it's no longer defined or used.
17600 Also, s/cstdio.h/cstdio/.
17602 2002-01-03 Akim Demaille <akim@epita.fr>
17604 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
17606 2002-01-03 Akim Demaille <akim@epita.fr>
17608 * src/parse-skel.y (process_skeleton): Don't bind the parser's
17609 tracing code to --trace, wait for a better --trace option, with
17612 2002-01-03 Akim Demaille <akim@epita.fr>
17614 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
17615 The ISO C++ standard is extremely clear about it: stderr is
17616 considered a macro, not a regular symbol (see table 94 `Header
17617 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
17618 Therefore std:: does not apply to it. It still does with fprintf.
17619 Also, s/cstdio.h/cstdio/.
17621 2002-01-03 Akim Demaille <akim@epita.fr>
17623 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
17624 for non system headers.
17626 2002-01-02 Akim Demaille <akim@epita.fr>
17628 Equip the skeleton chain with location tracking, runtime trace,
17629 pure parser and scanner.
17631 * src/parse-skel.y: Request a pure parser, locations, and prefix
17633 (%union): Having several members with the same type does not help
17634 type mismatches, simplify.
17635 (YYPRINT, yyprint): New.
17636 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
17637 (skel_error): this.
17639 * src/scan-skel.l: Adjust to these changes.
17640 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
17641 (LOCATION_PRINT, skel_control_t): New.
17643 2001-12-30 Akim Demaille <akim@epita.fr>
17645 * src/parse-skel.y: Get rid of the shift/reduce conflict:
17646 replace `gb' with BLANKS.
17647 * src/scan-skel.l: Adjust.
17649 2001-12-30 Akim Demaille <akim@epita.fr>
17651 * src/system.h: We don't need nor want bcopy.
17652 Throw away MS-DOS crap: we don't need getpid.
17653 * configure.in: We don't need strndup. It was even causing
17654 problems: because Flex includes the headers *before* us,
17655 _GNU_SOURCE is not defined by config.h, and therefore strndup was
17657 * lib/xstrndup.c: New.
17658 * src/scan-skel.l: Use it.
17659 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
17660 * src/parse-skel.y: Use %directives instead of #defines.
17662 2001-12-30 Akim Demaille <akim@epita.fr>
17664 * src/skeleton.h: New.
17665 * src/output.c (output_parser, output_master_parser): Remove, dead
17667 * src/output.h (get_lines_number, actions_output, guards_output)
17668 (token_definitions_output): Prototype them.
17669 * src/parse-skel.y: Add the license notice.
17670 Include output.h and skeleton.h.
17671 (process_skeleton): Returns void, and takes a single parameter.
17672 * src/scan-skel.l: Add the license notice.
17673 Include skeleton.h.
17674 Don't use %option yylineno: it seems that then Flex imagines
17675 REJECT has been used, and therefore it won't reallocate its
17676 buffers (which makes no other sense to me than a bug). It results
17677 in warnings for `unused: yy_flex_realloc'.
17679 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
17681 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17682 (MUSCLE_INSERT_PREFIX): ...to there.
17683 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17684 (MUSCLE_INSERT_PREFIX): Move from here...
17686 * src/bison.hairy: Add a section directive. Put braces around muscle
17687 names. This parser skeleton is still broken, but Bison should not
17688 choke on a bad muscle 'syntax'.
17689 * src/bison.simple: Add a section directive. Put braces around muscle
17692 * src/files.h (strsuffix, stringappend): Add declarations.
17693 (tab_extension): Add declaration.
17694 (short_base_name): Add declaration.
17696 * src/files.c (strsuffix, stringappend): No longer static. These
17697 functions are used in the skeleton parser.
17698 (tab_extension): New.
17699 (compute_base_names): Use the computations done in this function
17700 to guess if the generated parsers should have '.tab' in their
17702 (short_base_name): No longer static.
17704 * src/output.c (output_skeleton): New.
17705 (output): Disable call to output_master_parser, and give a try to
17706 a new skeleton handling system.
17707 (guards_output, actions_output): No longer static.
17708 (token_definitions_output, get_lines_number): No longer static.
17710 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
17712 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
17715 * src/parse-skel.y: New file.
17716 * src/scan-skel.l: New file.
17718 2001-12-29 Akim Demaille <akim@epita.fr>
17720 %name-prefix is broken.
17722 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
17723 Adjust all dependencies.
17724 * tests/headers.at (export YYLTYPE): Strengthen this test: use
17727 Renaming yylval but not yylloc is not consistent. Now we do.
17729 * src/bison.simple: Prefix yylloc if used.
17730 * doc/bison.texinfo (Decl Summary): Document that.
17732 2001-12-29 Akim Demaille <akim@epita.fr>
17734 * doc/bison.texinfo: Promote `%long-directive' over
17736 Remove all references to fixed-output-files, yacc is enough.
17738 2001-12-29 Akim Demaille <akim@epita.fr>
17740 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
17741 user prologue. These are defaults.
17742 * tests/actions.at (Mid-rule actions): Make sure the user can
17743 define YYDEBUG and YYERROR_VERBOSE.
17745 2001-12-29 Akim Demaille <akim@epita.fr>
17747 * src/output.c (header_output): Don't forget to export YYLTYPE and
17749 * tests/headers.at (export YYLTYPE): New, make sure it does.
17750 * tests/regression.at (%union and --defines, Invalid CPP headers):
17752 * tests/headers.at: here.
17754 2001-12-29 Akim Demaille <akim@epita.fr>
17756 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
17758 2001-12-29 Akim Demaille <akim@epita.fr>
17760 * tests/actions.at (Mid-rule actions): Output on a single line
17761 instead of several.
17763 2001-12-29 Akim Demaille <akim@epita.fr>
17765 * doc/bison.texinfo: Formatting changes.
17767 2001-12-29 Akim Demaille <akim@epita.fr>
17769 Don't store the token defs in a muscle, just be ready to output it
17770 on command. Now possible via `symbols'. Fixes a memory leak.
17772 * src/output.c (token_definitions_output): New.
17773 (output_parser, header_output): Use it.
17774 * src/reader.c (symbols_save): Remove.
17776 2001-12-29 Akim Demaille <akim@epita.fr>
17778 * src/bison.simple: Do not provide a default for YYSTYPE and
17779 YYLTYPE before the user's prologue. Otherwise it's hardly... a
17782 2001-12-29 Akim Demaille <akim@epita.fr>
17784 Mid-rule actions are simply... ignored!
17786 * src/reader.c (readgram): Be sure to attach mid-rule actions to
17787 the empty-rule associated to the dummy symbol, not to the host
17789 * tests/actions.at (Mid-rule actions): New.
17791 2001-12-29 Akim Demaille <akim@epita.fr>
17795 * src/reader.c (reader): Free grammar.
17797 2001-12-29 Akim Demaille <akim@epita.fr>
17801 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
17802 since it allocates it for each state, although only one is needed.
17803 (allocate_storage): Do it here.
17805 2001-12-29 Akim Demaille <akim@epita.fr>
17807 * src/options.h, src/options.c (create_long_option_table): Rename
17809 (long_option_table_new): this, with a clearer prototype.
17810 (percent_table): Remove, unused,
17811 * src/getargs.c (getargs): Adjust.
17813 2001-12-29 Akim Demaille <akim@epita.fr>
17815 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
17816 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
17819 2001-12-29 Akim Demaille <akim@epita.fr>
17821 * src/lalr.c (build_relations): Rename `states' as `states1'.
17822 Sorry, I don't understand exactly what it is, no better name...
17824 2001-12-29 Akim Demaille <akim@epita.fr>
17826 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
17827 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
17828 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
17831 2001-12-29 Akim Demaille <akim@epita.fr>
17833 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
17836 2001-12-29 Akim Demaille <akim@epita.fr>
17838 * src/reader.c, src/reader.h (user_toknums): Remove.
17839 Adjust all users to use symbols[i]->user_token_number.
17841 2001-12-29 Akim Demaille <akim@epita.fr>
17843 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
17844 Adjust all users to use symbols[i]->prec or ->assoc.
17846 2001-12-29 Akim Demaille <akim@epita.fr>
17848 * src/reader.c, src/reader.h (tags): Remove.
17849 Adjust all users to use symbols[i]->tag.
17851 2001-12-29 Akim Demaille <akim@epita.fr>
17853 * src/gram.h, src/gram.c (symbols): New, similar to state_table
17855 * src/reader.c (packsymbols): Fill this table.
17857 * src/conflicts.c (resolve_sr_conflict): Adjust.
17858 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
17860 Use symbols[i]->tag instead of tags[i].
17862 2001-12-29 Akim Demaille <akim@epita.fr>
17864 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
17865 In addition, put a comment in there, to replace...
17866 * tests/regression.at (%union and C comments): Remove.
17868 2001-12-29 Akim Demaille <akim@epita.fr>
17870 * tests/regression.at (Web2c Actions): Blindly move the actual
17871 output as expected output. The contents *seem* right to me, but I
17872 can't pretend reading perfectly parser tables... Nonetheless, all
17873 the other tests pass correctly, the table look OK, even though the
17874 presence of `$axiom' is to be noted: AFAICS it is useless (but
17877 2001-12-29 Akim Demaille <akim@epita.fr>
17879 * src/reader.c (readgram): Don't add the rule 0 if there were no
17880 rules read. In other words, add it _after_ having performed
17881 grammar sanity checks.
17882 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
17884 2001-12-29 Akim Demaille <akim@epita.fr>
17886 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
17887 visible, and some states have now a different number.
17889 2001-12-29 Akim Demaille <akim@epita.fr>
17891 * src/reader.c (readgram): Bind the initial rule's lineno to that
17893 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
17894 (Solved SR Conflicts): Adjust rule 0's line number.
17896 2001-12-29 Akim Demaille <akim@epita.fr>
17898 Fix the `GAWK Grammar' failure.
17900 * src/LR0.c (final_state): Initialize to -1 so that we do compute
17901 the reductions of the first state which was mistakenly confused
17902 with the final state because precisely final_state was initialized
17904 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
17905 now noticed by Bison.
17906 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
17907 have a reduction on $default.
17909 2001-12-29 Akim Demaille <akim@epita.fr>
17911 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
17913 * src/closure.c (print_closure): Likewise.
17914 * src/derives.c (print_derives): Likewise.
17915 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
17918 2001-12-29 Akim Demaille <akim@epita.fr>
17920 * src/lalr.c (lookaheads_print): New.
17921 (lalr): Call it when --trace-flag.
17922 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
17925 2001-12-29 Akim Demaille <akim@epita.fr>
17927 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
17928 when walking through ritem, even via rule->rhs.
17929 * src/reduce.c (dump_grammar, useful_production, reduce_output)
17930 (useful_production, useless_nonterminals): Likewise.
17931 (reduce_grammar_tables): Likewise, plus update nritems.
17932 * src/nullable.c (set_nullable): Likewise.
17933 * src/lalr.c (build_relations): Likewise.
17934 * tests/sets.at (Nullable): Adjust.
17935 Fortunately, now, the $axiom is no longer nullable.
17937 2001-12-29 Akim Demaille <akim@epita.fr>
17939 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
17941 * src/gram.c (ritem_longest_rhs): Likewise.
17942 * src/reduce.c (nonterminals_reduce): Likewise.
17943 * src/print_graph.c (print_graph): Likewise.
17944 * src/output.c (output_rule_data): Likewise.
17945 * src/nullable.c (set_nullable): Likewise.
17947 2001-12-29 Akim Demaille <akim@epita.fr>
17949 * src/output.c: Comment changes.
17951 2001-12-27 Paul Eggert <eggert@twinsun.com>
17953 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
17954 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
17955 Sparc, as they were causing more porting problems than the
17956 (minor) performance improvement was worth.
17958 Also, catch up with 1.31's YYSTD.
17960 2001-12-27 Akim Demaille <akim@epita.fr>
17962 * src/output.c (output_gram): Rely on nritems, not the
17963 0-sentinel. See below.
17964 Use -1 as separator, not 0.
17965 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
17966 Rely on -1 as separator in yyrhs, instead of 0.
17967 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
17968 twice `Now at end of input', therefore there are two lines less to
17971 2001-12-27 Akim Demaille <akim@epita.fr>
17973 * tests/regression.at (Unresolved SR Conflicts):
17974 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
17977 2001-12-27 Akim Demaille <akim@epita.fr>
17979 * src/LR0.c (new_state): Recognize the final state by the fact it
17980 is reached by eoftoken.
17981 (insert_start_shifting_state, insert_eof_shifting_state)
17982 (insert_accepting_state, augment_automaton): Remove, since now
17983 these states are automatically computed from the initial state.
17984 (generate_states): Adjust.
17985 * src/print.c: When reporting a rule number to the user, substract
17986 1, so that the axiom rule is rule 0, and the first user rule is 1.
17987 * src/reduce.c: Likewise.
17988 * src/print_graph.c (print_core): For the time being, just as for
17989 the report, depend upon --trace-flags to dump the full set of
17991 * src/reader.c (readgram): Once the grammar read, insert the rule
17992 0: `$axiom: START-SYMBOL $'.
17993 * tests/set.at: Adjust: rule 0 is now displayed, and since the
17994 number of the states has changed (the final state is no longer
17995 necessarily the last), catch up.
17997 2001-12-27 Akim Demaille <akim@epita.fr>
17999 Try to make the use of the eoftoken valid. Given that its value
18000 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
18001 is used instead of > 0 where appropriate, (ii), depend upon nritems
18002 instead of the 0-sentinel.
18004 * src/gram.h, src/gram.c (nritems): New.
18005 Expected to be duplication of nitems, but for the time being...
18006 * src/reader.c (packgram): Assert nritems and nitems are equal.
18007 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
18008 * src/closure.c (print_closure, print_fderives): Likewise.

18013 2001-12-27 Akim Demaille <akim@epita.fr>
18015 * src/main.c (main): If there are complains after grammar
18016 reductions, then output the report anyway if requested, then die.
18017 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
18018 * src/reader.c (eoftoken): New.
18019 (parse_token_decl): If the token being defined has value `0', it
18021 (packsymbols): No longer hack `tags' to insert `$' by hand.
18022 Be sure to preserve the value of the eoftoken.
18023 (reader): Make sure eoftoken is defined.
18024 Initialize nsyms to 0: now eoftoken is created just like the others.
18025 * src/print.c (print_grammar): Don't special case the eof token.
18026 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
18027 lie anyway, albeit pleasant.
18028 * tests/calc.at: Exercise error messages with eoftoken.
18029 Change the grammar so that empty input is invalid.
18030 Adjust expectations.
18031 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
18033 2001-12-27 Akim Demaille <akim@epita.fr>
18035 * configure.in: Check the protos of strchr ans strspn.
18036 Replace strchr if needed.
18037 * src/system.h: Provide the protos of strchr, strspn and memchr if
18039 * lib/strchr.c: New.
18040 * src/reader.c (symbols_save): Use strchr.
18042 2001-12-27 Akim Demaille <akim@epita.fr>
18044 * src/print.c, src/print_graph.c (escape): New.
18045 Use it to quote the TAGS outputs.
18046 * src/print_graph.c (print_state): Now errors are in red, and
18047 reductions in green.
18048 Prefer high to wide: output the state number on a line of its own.
18050 2001-12-27 Akim Demaille <akim@epita.fr>
18052 * src/state.h, src/state.c (reductions_new): New.
18053 * src/LR0.c (set_state_table): Let all the states have a
18054 `reductions', even if reduced to 0.

18073 2001-12-27 Akim Demaille <akim@epita.fr>
18075 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
18076 * src/print.c: here.
18077 (lookaheadset, shiftset): New, used as additional storage by
18079 (print_results): Adjust.
18080 (print_shifts, print_gotos, print_errs): New, extracted from...
18081 (print_actions): here.
18082 * src/print_graph.c (print_actions): Remove dead code.
18084 2001-12-27 Akim Demaille <akim@epita.fr>
18086 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
18089 2001-12-27 Akim Demaille <akim@epita.fr>
18091 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
18092 (build_relations): Adjust.
18094 2001-12-27 Akim Demaille <akim@epita.fr>
18096 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
18099 2001-12-27 Akim Demaille <akim@epita.fr>
18101 * src/reader.c (packgram): Catch nitems overflows.
18103 2001-12-27 Akim Demaille <akim@epita.fr>
18105 * src/files.c, src/files.h (guard_obstack): Remove.
18106 * src/output.c (output): Adjust.
18107 * src/reader.c (parse_braces): New, factoring...
18108 (copy_action, copy_guard): these two which are renamed as...
18109 (parse_action, parse_guard): these.
18110 As a voluntary consequence, using braces around guards is now
18113 2001-12-27 Akim Demaille <akim@epita.fr>
18115 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
18116 * src/reader.c (symbol_list): `guard' and `guard_line' are new
18118 (symbol_list_new): Adjust.
18119 (copy_action): action_line is the first line, not the last.
18120 (copy_guard): Just as for actions, store the `action' only, not
18121 the switch/case/break flesh.
18122 Don't parse the user action that might follow the guard, let...
18123 (readgram): do it, i.e., now, there can be an action after a
18125 In other words the guard is just explicitly optional.
18126 (packgram): Adjust.
18127 * src/output.c (guards_output): New.
18128 (output_parser): Call it when needed.
18129 (output): Also free the guard and attrs obstacks.
18130 * src/files.c, src/files.h (obstack_save): Remove.
18131 (output_files): Remove.
18132 As a result, if one needs the former `.act' file, using an
18133 appropriate skeleton which requires actions and guards is now
18135 * src/main.c (main): Adjust.
18136 * tests/semantic.at: New.
18137 * tests/regression.at: Use `input.y' as input file name.
18138 Avoid 8+3 problems by requiring input.c when the test needs the

18143 * src/reader.c (symbol_list_new): Be sure to initialize all the
18146 2001-12-27 Akim Demaille <akim@epita.fr>
18148 All the hacks using a final pseudo state are now useless.
18150 * src/LR0.c (set_state_table): state_table holds exactly nstates.
18151 * src/lalr.c (nLA): New.
18152 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
18153 instead of lookaheadsp from the pseudo state (nstate + 1).
18155 2001-12-27 Akim Demaille <akim@epita.fr>
18157 * src/output.c (action_row, token_actions): Use a state_t instead
18158 of a integer, and nlookaheads instead of the following state's

18165 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
18166 (conflicts_print, print_reductions): Use a state_t instead of an
18167 integer when referring to a state.
18168 As much as possible, depend upon nlookaheads, instead of the
18169 `lookaheadsp' member of the following state (since lookaheads of
18170 successive states are successive, the difference between state n + 1
18171 and n served as the number of lookaheads for state n).
18172 * src/lalr.c (add_lookback_edge): Likewise.
18173 * src/print.c (print_core, print_actions, print_state)
18174 (print_results): Likewise.
18175 * src/print_graph.c (print_core, print_actions, print_state)

18184 Add plenty of `static'.
18186 2001-12-27 Akim Demaille <akim@epita.fr>
18188 * src/output.c (prepare): Drop the muscle `ntbase' which
18189 duplicates ntokens.
18190 * src/bison.simple: Formatting/comment changes.
18191 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
18192 is an undocumented synonym.
18194 2001-12-22 Akim Demaille <akim@epita.fr>
18196 * src/output.c (output_table_data): Change the prototype to use
18197 `int' for array ranges: some invocations do pass an int, not a
18199 Reported by Wayne Green.
18201 2001-12-22 Akim Demaille <akim@epita.fr>
18203 Some actions of web2c.y are improperly triggered.
18204 Reported by Mike Castle.
18206 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
18207 * tests/regression.at (Web2c): Rename as...
18208 (Web2c Report): this.
18209 (Web2c Actions): New.
18211 2001-12-22 Akim Demaille <akim@epita.fr>
18213 Reductions in web2c.y are improperly reported.
18214 Reported by Mike Castle.
18216 * src/conflicts.c (print_reductions): Fix.
18217 * tests/regression.at (Web2c): New.
18219 2001-12-18 Akim Demaille <akim@epita.fr>
18221 Some host fail on `assert (!"foo")', which expands to
18222 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
18223 Reported by Nelson Beebee.
18225 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
18226 `#define it_succeeded 0' and `assert (it_succeeded)'.
18228 2001-12-17 Marc Autret <autret_m@epita.fr>
18230 * src/bison.simple: Don't hard code the skeleton line and filename.
18231 * src/output.c (output_parser): Rename 'line' as 'output_line'.
18232 New line counter 'skeleton_line' (skeleton-line muscle).
18234 2001-12-17 Paul Eggert <eggert@twinsun.com>
18236 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
18237 YYDEBUG must be defined to a nonzero value.
18239 * src/bison.simple (yytname): Do not assume that the user defines
18240 YYDEBUG to a properly parenthesized expression.
18242 2001-12-17 Akim Demaille <akim@epita.fr>
18244 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
18245 nlookaheads is a new member.
18247 * src/lalr.h (nlookaheads): Remove this orphan declaration.
18248 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
18251 2001-12-17 Akim Demaille <akim@epita.fr>
18253 * src/files.h, src/files.c (open_files, close_files): Remove.
18254 * src/main.c (main): Don't open/close files, nor invoke lex_free,
18256 * src/reader.c (reader): Do it.
18258 2001-12-17 Akim Demaille <akim@epita.fr>
18260 * src/conflicts.c (print_reductions): Formatting changes.
18262 2001-12-17 Akim Demaille <akim@epita.fr>
18264 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
18265 (flush_reduce): New.
18266 (resolve_sr_conflict): Adjust.
18268 2001-12-17 Akim Demaille <akim@epita.fr>
18270 * src/output.c (output_obstack): Be static and rename as...
18271 (format_obstack): this, to avoid any confusion with files.c's
18273 * src/reader.h (muscle_obstack): Move to...
18274 * src/output.h: here, since it's defined in output.c.
18276 2001-12-17 Akim Demaille <akim@epita.fr>
18278 * src/output.c (action_row, save_column, default_goto)
18279 (sort_actions, matching_state, pack_vector): Better variable
18282 2001-12-17 Akim Demaille <akim@epita.fr>
18284 * src/output.c: Various formatting changes.
18286 2001-12-17 Akim Demaille <akim@epita.fr>
18288 * src/files.c (output_files): Free the output_obstack.
18289 * src/main.c (main): Call print and print_graph conditionally.
18290 * src/print.c (print): Work unconditionally.
18291 * src/print_graph.c (print_graph): Work unconditionally.
18292 * src/conflicts.c (log_resolution): Output only if verbose_flag.
18294 2001-12-16 Marc Autret <autret_m@epita.fr>
18296 * src/output.c (actions_output): Fix. When we use %no-lines,
18297 there is one less line per action.
18299 2001-12-16 Marc Autret <autret_m@epita.fr>
18301 * src/bison.simple: Remove a useless #line directive.
18302 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
18303 * src/output.c (get_lines_number): New.
18304 (output_parser): Adjust, now takes care about the lines of a
18306 Fix line numbering.
18307 (actions_output): Computes the number of lines taken by actions.
18308 (output_master_parser): Insert new skeleton which is the name of
18309 the output parser file name.
18311 2001-12-15 Marc Autret <autret_m@epita.fr>
18313 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
18315 2001-12-15 Marc Autret <autret_m@epita.fr>
18317 * src/output.c (output_gram): Keep track of the hairy one.
18319 2001-12-15 Akim Demaille <akim@epita.fr>
18321 Make `make distcheck' work.
18323 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
18324 system.h which uses libgettext.h.
18326 2001-12-15 Akim Demaille <akim@epita.fr>
18328 * src/nullable.c (set_nullable): Useless rules must be skipped,
18329 otherwise, since we range over their symbols, we might look at a
18330 nonterminal which no longer ``exists'', i.e., it is not counted in
18331 `nvars', hence we overflow our arrays.
18333 2001-12-15 Akim Demaille <akim@epita.fr>
18335 The header can also be produced directly, without any obstack!
18338 * src/files.c, src/files.h (defines_obstack): Remove.
18339 (compute_header_macro): Global.
18340 (defines_obstack_save): Remove.
18341 * src/reader.c (parse_union_decl): No longer output to
18342 defines_obstack: its content can be found in the `stype' muscle
18344 (output_token_translations): Merge into...
18345 (symbols_output): this.
18347 (symbols_save): this.
18349 * src/output.c (header_output): New.
18352 2001-12-15 Akim Demaille <akim@epita.fr>
18354 * src/reader.c (parse_union_decl): Instead of handling two obstack
18355 simultaneously, use one to define the `stype' muscle, and use the
18356 value of the latter to fill defines_obstack.
18357 (copy_comment): Remove.
18358 (copy_comment2): Work for a single obstack.
18360 (copy_comment): this.
18362 2001-12-15 Akim Demaille <akim@epita.fr>
18364 * src/lex.c, src/lex.h (xgetc): No longer static.
18365 * src/reader.c (parse_union_decl): Revamp.
18367 2001-12-15 Akim Demaille <akim@epita.fr>
18369 Still making progress in separating Bison into (i) input, (ii)
18370 process, (iii) output: now we can directly output the parser file
18371 without using table_obstack at all.
18373 * src/files.c, src/files.h (table_obstack): Bye bye.
18374 (parser_file_name): New.
18375 * src/files.c (compute_output_file_names): Compute it.
18376 * src/output.c (actions_output, output_parser)
18377 (output_master_parser): To a file instead of an obstack.
18379 2001-12-15 Akim Demaille <akim@epita.fr>
18381 Attach actions to rules, instead of pre-outputting them to
18384 * src/gram.h (rule_t): action and action_line are new members.
18385 * src/reader.c (symbol_list): Likewise.
18386 (copy_action): Save the actions within the rule.
18387 (packgram): Save them in rule_table.
18388 * src/output.c (actions_output): New.
18389 (output_parser): Use it on `%%actions'.
18390 (output_rule_data): Don't free rule_table.
18392 (prepare): Don't save the `action' muscle.
18393 * src/bison.simple: s/%%action/%%actions/.
18395 2001-12-15 Akim Demaille <akim@epita.fr>
18397 * src/reader.c (copy_action): When --yacc, don't append a `;'
18398 to the user action: let it fail if lacking.
18399 Suggested by Arnold Robbins and Tom Tromey.
18401 2001-12-14 Akim Demaille <akim@epita.fr>
18403 * src/lex.c (literalchar): Simply return the char you decoded, non
18404 longer mess around with obstacks and int pointers.
18405 Adjust all callers.
18407 2001-12-14 Akim Demaille <akim@epita.fr>
18409 * src/lex.c (literalchar): Don't escape the special characters,
18410 just decode them, and keep them as char (before, eol was output as
18411 the 2 char string `\n' etc.).
18412 * src/output.c (output_rule_data): Use quotearg to output the
18415 2001-12-13 Paul Eggert <eggert@twinsun.com>
18417 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
18418 Do not infringe on the global user namespace when using C++.
18419 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
18420 All uses of `fprintf' and `stderr' changed.
18422 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
18424 2001-12-13 Akim Demaille <akim@epita.fr>
18426 The computation of nullable is broken: it doesn't handle empty
18429 * tests/torture.at (GNU AWK Grammar): New.
18430 * tests/sets.at (Nullable): New.
18431 * src/nullable.c (set_nullable): Instead of blindly looping over
18432 `ritems', loop over the rules, and then over their rhs's.
18434 Work around Autotest bugs.
18436 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
18437 frame, because Autotest understand lines starting with a `+' as
18438 traces from the shell. Then, they are not processed properly.
18439 Admittedly an Autotest bug, but we don't have time to wait for
18440 Autotest to catch up.
18441 * tests/regression.at (Broken Closure): Adjust to the new table
18444 * tests/sets.at: here.
18446 2001-12-13 Akim Demaille <akim@epita.fr>
18448 * src/closure.c (closure): Use nrules instead of playing tricks
18449 with BITS_PER_WORD.
18451 2001-12-13 Akim Demaille <akim@epita.fr>
18453 * src/print.c (print_actions): Output the handling of `$' as the
18454 traces do: shifting the token EOF. Before EOF was treated as a
18456 * tests/regression.at: Adjust some tests.
18457 * src/print_graph.c (print_core): Complete the set of items via
18458 closure. The next-to-final and final states are still unsatisfying,
18459 but that's to be addressed elsewhere.
18460 No longer output the rule numbers, but do output the state number.
18461 A single loop for the shifts + gotos is enough, but picked a
18462 distinct color for each.
18463 (print_graph): Initialize and finalize closure.
18465 2001-12-13 Akim Demaille <akim@epita.fr>
18467 * src/reader.c (readgram): Remove dead code, an strip useless
18469 (get_type): Remove, unused.
18471 2001-12-12 Akim Demaille <akim@epita.fr>
18473 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
18474 on that of lib/error.c.
18476 2001-12-12 Akim Demaille <akim@epita.fr>
18478 Some hosts don't like `/' in includes.
18480 * src/system.h: Include libgettext.h without qualifying the path.
18481 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
18484 2001-12-11 Marc Autret <autret_m@epita.fr>
18486 * src/output.c (output_parser): Remove useless muscle.
18488 2001-12-11 Marc Autret <autret_m@epita.fr>
18490 * src/bison.simple: Remove #line just before %%epilogue. It
18491 is now handled in ...
18492 * src/reader.c (read_additionnal_code): Add the output of a
18493 #line for the epilogue.
18495 2001-12-10 Marc Autret <autret_m@epita.fr>
18497 * src/reader.c (copy_definition): Re-use CPP-outed code which
18498 replace precedent remove.
18499 * src/bison.simple: Remove #line before %%prologue because
18500 %%input-line is wrong at this time.
18502 2001-12-10 Marc Autret <autret_m@epita.fr>
18504 * src/reader.c (symbols_output): Clean up.
18505 * src/output.c (output_gram, output): Clean up.
18507 2001-12-10 Akim Demaille <akim@epita.fr>
18509 * src/lalr.c (initialize_lookaheads): New. Extracted from...
18510 * src/LR0.c (set_state_table): here.
18511 * src/lalr.c (lalr): Call it.
18513 2001-12-10 Akim Demaille <akim@epita.fr>
18515 * src/state.h (shifts): Remove the `number' member: shifts are
18516 attached to state, hence no longer need to be labelled with a
18519 2001-12-10 Akim Demaille <akim@epita.fr>
18521 Now that states have a complete set of members, the linked list of
18522 shifts is useless: just fill directly the state's shifts member.
18524 * src/state.h (shifts): Remove the `next' member.
18525 * src/LR0.c (first_state, last_state): Remove.
18526 Adjust the callers.
18527 (augment_automaton): Don't look for the shifts that must be added
18528 a shift on EOF: it is those of the state we looked for! But now,
18529 since shifts are attached, it is no longer needed to looking
18530 merely by its id: its number.
18532 2001-12-10 Akim Demaille <akim@epita.fr>
18534 * src/LR0.c (augment_automaton): Better variable locality.
18535 Remove an impossible branch: if there is a state corresponding to
18536 the start symbol being shifted, then there is shift for the start
18537 symbol from the initial state.
18539 2001-12-10 Akim Demaille <akim@epita.fr>
18541 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
18542 only when appropriate: when insert_start_shifting_state' is not
18544 * tests/regression.at (Rule Line Numbers): Adjust.
18546 2001-12-10 Akim Demaille <akim@epita.fr>
18548 * src/LR0.c (augment_automaton): Now that all states have shifts,
18549 merge the two cases addition shifts to the initial state.
18551 2001-12-10 Akim Demaille <akim@epita.fr>
18553 * src/lalr.c (set_state_table): Move to...
18555 * src/lalr.c (lalr): Don't call it...
18556 * src/LR0.c (generate_states): do it.
18557 * src/LR0.h (first_state): Remove, only the table is used.
18559 2001-12-10 Akim Demaille <akim@epita.fr>
18561 * src/LR0.h (first_shift, first_reduction): Remove.
18562 * src/lalr.c: Don't use first_shift: find shifts through the
18565 2001-12-10 Akim Demaille <akim@epita.fr>
18567 * src/LR0.c: Attach shifts to states as soon as they are
18569 * src/lalr.c (set_state_table): Instead of assigning shifts to
18570 state, just assert that the mapping was properly done.
18572 2001-12-10 Akim Demaille <akim@epita.fr>
18574 * src/LR0.c (insert_start_shift): Rename as...
18575 (insert_start_shifting_state): this.
18576 (insert_eof_shifting_state, insert_accepting_state): New.
18577 (augment_automaton): Adjust.
18578 Better locality of the variables.
18579 When looking if the start_symbol is shifted from the initial
18580 state, using `while (... symbol != start_symbol ...)' sounds
18581 better than `while (... symbol < start_symbol ...)': If fail
18582 to see how the order between symbols could be relevant!
18584 2001-12-10 Akim Demaille <akim@epita.fr>
18586 * src/getargs.h: Don't declare `spec_name_prefix' and
18587 `spec_file_prefix', declared by src/files.h.
18588 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
18589 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
18590 * src/output.c (prepare): Adjust.
18591 * src/reader.c (symbols_output): Likewise.
18592 * src/vmsgetargs.c: Vaguely adjust, but who cares?
18594 2001-12-10 Akim Demaille <akim@epita.fr>
18596 * src/muscle_tab.c (muscle_init): NULL is a better default than
18599 2001-12-10 Akim Demaille <akim@epita.fr>
18601 * src/reader.c (reader): Calling symbols_output once is enough.
18603 2001-12-10 Akim Demaille <akim@epita.fr>
18605 Now that states have a complete set of members, the linked list of
18606 reductions is useless: just fill directly the state's reductions
18609 * src/state.h (struct reductions): Remove member `number' and
18611 * src/LR0.c (first_reduction, last_reduction): Remove.
18612 (save_reductions): Don't link the new reductions, store them in
18614 * src/lalr.c (set_state_table): No need to attach reductions to
18615 states, it's already done.
18616 * src/output.c (output_actions): No longer free the shifts, then
18617 the reductions, then the states: free all the states and their
18620 2001-12-10 Akim Demaille <akim@epita.fr>
18622 * src/options.c (OPTN, DRTV, BOTH): New.
18623 (option_table): Use them.
18625 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
18626 the job of system.h.
18627 * src/options.c: Don't include stdio.h and xalloc.h for the same
18630 2001-12-10 Akim Demaille <akim@epita.fr>
18632 * src/output.c (output, prepare): Make sure the values of the
18633 muscles `action' and `prologue' are 0-terminated.
18635 2001-12-10 Akim Demaille <akim@epita.fr>
18637 Clean up GCC warnings.
18639 * src/reader.c (copy_action): `buf' is not used.
18640 (parse_skel_decl): Be static.
18641 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
18642 * src/options.h (create_long_option_table): Have a real prototype.
18643 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
18644 (hash_delete_at): Return const void *.
18645 Adjust casts to preserve the const.
18647 2001-12-10 Akim Demaille <akim@epita.fr>
18649 * configure.in: Require 2.52g.
18650 M4 is not needed, but AUTOM4TE is.
18651 * m4/m4.m4: Remove.
18652 * tests/Makefile.am: Adjust.
18654 2001-12-10 Akim Demaille <akim@epita.fr>
18656 One structure for states is enough, even though theoretically
18657 there are LR(0) states and LALR(1) states.
18659 * src/lalr.h (state_t): Remove.
18660 (state_table): Be state_t **, not state_t *.
18661 * src/state.h (core, CORE_ALLOC): Rename as...
18662 (state_t, STATE_ALLOC): this.
18663 Add the LALR(1) members: shifts, reductions, errs.
18664 * src/LR0.c (state_table): Rename as...
18665 (state_hash): this, to avoid name clashes with the global
18667 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
18668 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
18670 2001-12-10 Akim Demaille <akim@epita.fr>
18672 Bison dumps core on bash.y.
18673 Reported by Pascal Bart.
18675 * src/warshall.c (bitmatrix_print): New.
18677 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
18678 j must be the outer loop.
18679 * tests/regression.at (Broken Closure): New.
18681 2001-12-05 Akim Demaille <akim@epita.fr>
18683 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
18685 Reported by Peter Hamorsky.
18687 2001-12-05 Akim Demaille <akim@epita.fr>
18689 * src/conflicts.c (err_table): Remove.
18690 (resolve_sr_conflict): Adjust.
18691 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
18693 (state_t.reductions, state_t.shifts): this.
18695 2001-12-05 Akim Demaille <akim@epita.fr>
18697 * src/reduce.c (reduce_grammar_tables): No longer disable the
18698 removal of useless rules via CPP but via `if (0)', so that the
18699 compiler still check the code is valid.
18700 For instance, it should have noticed `rline' no longer exists: use
18701 the `line' member of rule_t.
18702 * src/gram.c (dummy, rline): Remove, unused.
18704 2001-12-05 Akim Demaille <akim@epita.fr>
18706 * src/output.c (pack_vector): Use assert, not berror.
18707 * src/main.c (berror): Remove, unused.
18709 2001-12-05 Akim Demaille <akim@epita.fr>
18711 New experimental feature: if --verbose --trace output all the
18712 items of a state, not only its kernel.
18714 * src/print.c (print_core): If `trace_flag', then invoke closure
18715 before outputting the items of the state (print_core is no longer
18716 a correct name them).
18717 (print_results): Invoke new_closure/free_closure if needed.
18719 2001-12-05 Akim Demaille <akim@epita.fr>
18721 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
18722 * src/closure.c, src/closure.h (itemsetsize): Rename as...
18723 (nitemset): for consistency with the rest of the project.
18725 2001-12-05 Akim Demaille <akim@epita.fr>
18727 * src/closure.c (print_closure): Improve.
18728 (closure): Use it for printing input and output.
18730 2001-12-05 Akim Demaille <akim@epita.fr>
18732 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
18733 indexed by nonterminals.
18735 2001-12-05 Akim Demaille <akim@epita.fr>
18737 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

18753 2001-12-05 Akim Demaille <akim@epita.fr>
18755 * src/output.c (action_row): De-obfuscate
18756 using the good o' techniques: arrays not pointers, variable
18757 locality, BITISSET, RESETBIT etc.
18759 2001-12-05 Akim Demaille <akim@epita.fr>
18761 Pessimize the code to simplify it: from now on, all the states
18762 have a valid SHIFTS, which NSHIFTS is possibly 0.
18764 * src/LR0.c (shifts_new): Be global and move to..
18765 * src/state.c, src/state.h: here.
18766 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
18767 * src/print_graph: Adjust.
18769 2001-12-05 Akim Demaille <akim@epita.fr>
18771 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
18772 * src/conflicts.c: Use it.
18773 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
18774 incorrectly ``simplified''.
18776 2001-12-05 Akim Demaille <akim@epita.fr>
18778 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
18779 using the good o' techniques: arrays not pointers, variable
18780 locality, BITISSET, RESETBIT etc.
18782 2001-12-05 Akim Demaille <akim@epita.fr>
18784 * src/state.h (SHIFT_SYMBOL): New.

18789 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
18790 (print_reductions): De-obfuscate using the good o' techniques:

18795 * src/conflicts.c (print_reductions): Arrays, not pointers.

18814 2001-12-05 Akim Demaille <akim@epita.fr>
18816 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.

18819 2001-12-05 Akim Demaille <akim@epita.fr>
18821 * src/LR0.c (augment_automaton): Formatting changes.
18822 Better variable locality.

18826 * src/lalr.c (matrix_print): New.
18827 (transpose): Use it.

18832 * src/lalr.c (maxrhs): Move to...
18833 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
18834 * src/lalr.c (build_relations): Adjust.
18836 2001-12-05 Akim Demaille <akim@epita.fr>
18838 * src/lalr.c (transpose): Free the memory allocated to the
18839 argument, as it is replaced by the results by the unique caller.
18840 (build_relations): Merely invoke transpose: it handles the memory
18842 Improve variable locality.
18843 Avoid variables used as mere abbreviations.
18844 (compute_lookaheads): Use arrays instead of pointers.
18846 2001-12-05 Akim Demaille <akim@epita.fr>
18848 * src/lalr.c (initialize_F): Improve variable locality.
18849 Avoid variables used as mere abbreviations.

18862 2001-12-05 Akim Demaille <akim@epita.fr>
18864 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
18865 the handling of squeue.
18866 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
18868 2001-12-05 Akim Demaille <akim@epita.fr>
18870 Because useless nonterminals are now kept alive (instead of being
18871 `destroyed'), we now sometimes examine them, and store information
18872 related to them. Hence we need to know their number, and adjust
18873 memory allocations.
18875 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
18877 * src/LR0.c (allocate_itemsets): The memory allocated to
18878 `symbol_count' was used for two different purpose: once to count
18879 the number of occurrences of each symbol, and later reassigned to
18880 `shift_symbol', containing the symbol that can be shifted from a
18882 Deobfuscate, i.e., allocate, use and free `symbol_count' here
18884 (new_itemsets): Allocate `shift_symbol' here.
18885 (allocate_itemsets): symbol_count includes useless nonterminals.
18886 Make room for them.
18887 (free_storage): Use `free', not `XFREE', for pointers that cannot
18890 2001-12-05 Akim Demaille <akim@epita.fr>
18892 * src/nullable.c (set_nullable): Deobfuscate the handling of
18894 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
18896 2001-12-05 Akim Demaille <akim@epita.fr>
18898 * src/gram.c, src/gram.h (ritem_print): New.
18899 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
18900 (This useless function was defined only to work around VMS linkers
18901 that can't handle compilation units with variables only).
18902 * src/reduce.c (dump_grammar): Use it to trace the construction of
18905 2001-12-04 Paul Eggert <eggert@twinsun.com>
18907 * src/bison.simple (union yyalloc): Change member names
18908 to be the same as the stack names.
18909 (yyparse): yyptr is now union yyalloc *, not char *.
18910 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
18911 and may generate better code on some machines.
18912 (yystpcpy): Use prototype if __STDC__ is defined, not just
18913 if __cplusplus is defined.
18915 2001-11-30 Akim Demaille <akim@epita.fr>
18917 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
18918 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
18919 Gettext doesn't compile cleanly, and dies with -Werror.
18920 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
18921 Include WARNING_CFLAGS here.
18922 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
18923 before being defined.
18925 2001-11-27 Paul Eggert <eggert@twinsun.com>
18927 * lib/quotearg.h (quotearg_n, quotearg_n_style):
18928 First arg is int, not unsigned.
18929 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
18930 (SIZE_MAX, UINT_MAX): New macros.
18931 (quotearg_n_options): Abort if N is negative.
18932 Avoid overflow check on hosts where size_t is 64 bits and int
18933 is 32 bits, as overflow is impossible there.
18934 Fix off-by-one typo that caused unnecessary reallocation.
18936 2001-11-29 Paul Eggert <eggert@twinsun.com>
18938 Name space cleanup in generated parser.
18940 * doc/bison.texinfo (Bison Parser): Discuss system headers
18941 and their effect on the user name space.

18944 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
18945 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
18946 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
18948 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
18949 on user names when possible.
18951 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
18952 Simplify test for whather <alloca.h> exists.
18954 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
18956 (<stdio.h>): Include if YYDEBUG.
18958 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
18959 ! defined (yyoverflow) && ! defined (yymemcpy).
18961 (yymemcpy, yyparse): Rename local variables as needed so that
18962 they all begin with 'yy'.
18964 (yystrlen, yystpcpy): New functions.
18966 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
18969 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
18970 instead of relying on string.h functions. Use YYSTACK_ALLOC
18971 and YYSTACK_FREE instead of malloc and free.
18973 2001-11-30 Akim Demaille <akim@epita.fr>
18975 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
18976 before their first uses.

18985 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
18986 if body instead of `;' to pacify GCC's warnings.
18988 2001-11-30 Akim Demaille <akim@epita.fr>
18990 Instead of mapping the LHS of unused rules to -1, keep the LHS
18991 valid, but flag the rules as invalid.
18993 * src/gram.h (rule_t): `useful' is a new member.
18994 * src/print.c (print_grammar): Adjust.
18995 * src/derives.c (set_derives): Likewise.
18996 * src/reader.c (packgram, reduce_output): Likewise.

19007 2001-11-30 Akim Demaille <akim@epita.fr>
19009 * src/reduce.c (nonterminals_reduce): Instead of throwing away
19010 useless nonterminals, move them at the end of the symbol arrays.
19011 (reduce_output): Adjust.
19012 * tests/reduce.at (Useless Nonterminals): Adjust.

19024 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
19025 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
19027 (union yyalloc): New type.
19028 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
19029 an arbitrary restriction on hosts where size_t is wider than int.
19031 (yyparse): Don't dump core if alloca or malloc fails; instead, report
19032 a parser stack overflow. Allocate just one block of memory for all
19033 three stacks, instead of allocating three blocks; this typically is
19034 faster and reduces fragmentation.
19036 Do not limit the number of items in the stack to a value that fits
19037 in 'int', as this is an arbitrary limit on hosts with 64-bit
19038 size_t and 32-bit int.

21101 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
21102 s/PFILE1/BISON_HAIRY/.

21105 2000-11-03 Akim Demaille <akim@epita.fr>
21107 For some reason, this was not applied.
21109 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

21122 (done): Rename as...
21123 (output_files): this.
21124 Use `obstack_save'.
21125 * src/main.c (main): Don't use `atexit' to register `done', since
21126 it no longer has to remove tmp files, just call `output_files'
21127 when there are no errors.
21129 2000-11-02 Akim Demaille <akim@epita.fr>
21131 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
21132 `unlink': it's no longer used.
21133 * src/files.h: Formatting changes.
21135 2000-11-02 Akim Demaille <akim@epita.fr>
21137 Remove the last uses of mktemp and unlink/delete.
21139 * src/files.c (fdefines, ftable): Removed.

21199 * src/reader.c (copy_comment2): Expect the input stream to be on
21200 the `/' which is suspected to open a comment, instead of being
21201 called after `//' or `/*' was read.
21202 (copy_comment, copy_definition, parse_union_decl, copy_action)
21203 (copy_guard): Adjust.
21205 2000-10-16 Akim Demaille <akim@epita.fr>
21207 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

21231 2000-10-04 Akim Demaille <akim@epita.fr>
21233 When a literal string is used to define two different tokens,
21234 `bison -v' segfaults.
21235 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
21237 * tests/regression.m4: New file.
21238 Include the core of the sample provided by Piotr Gackiewicz.
21239 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
21242 2000-10-04 Akim Demaille <akim@epita.fr>
21244 * src/reader.c (parse_expect_decl): Keep `count' within the size
21248 2000-10-02 Paul Eggert <eggert@twinsun.com>
21250 * bison.s1 (yyparse): Assign the default value
21251 unconditionally, to avoid a GCC warning and make the parser a
21254 2000-10-02 Akim Demaille <akim@epita.fr>
21256 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
21259 2000-10-02 Akim Demaille <akim@epita.fr>
21261 * src/derives.c, src/print.c, src/reduce.c: To ease the
21262 translation, move some `\n' out of the translated strings.
21264 2000-10-02 Akim Demaille <akim@epita.fr>
21266 The location tracking mechanism is precious for parse error
21267 messages. Nevertheless, it is enabled only when `@n' is used in
21268 the grammar, which is a different issue (you can use it in error
21269 message, but not in the grammar per se). Therefore, there should
21270 be another means to enable it.
21272 * src/getargs.c (getargs): Support `--locations'.
21273 (usage): Report it.
21274 * src/getargs.h (locationsflag): Export it.
21275 * src/lex.c (percent_table): Support `%locations'.
21276 * src/reader.c (yylsp_needed): Remove this variable, now replaced
21277 with `locationsflag'.
21278 * doc/bison.texinfo: Document `--locations' and `%locations'.
21280 * tests/calc.m4: Test it.
21282 For regularity of the names, replace each
21283 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
21284 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
21285 In addition replace each `flag' with `_flag'.
21287 2000-10-02 Akim Demaille <akim@epita.fr>
21289 Also test parse error messages, including with YYERROR_VERBOSE.
21291 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
21293 Use it to check the computations.
21294 Use it to check `nonassoc' is honored.
21295 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
21296 `--yyerror-verbose'.
21297 (_AT_CHECK_CALC): Adjust to this option.
21298 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
21300 2000-10-02 Akim Demaille <akim@epita.fr>
21302 Test also `--verbose', `--defines' and `--name-prefix'. Testing
21303 the latter demonstrates a flaw in the handling of non debugging
21304 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
21305 was used in order to simplify:
21321 unfortunately this leads to a CPP conflict when
21322 `--name-prefix=foo' is used since it produces `#define yydebug
21325 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
21326 (YYDPRINTF): New macro.
21328 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
21330 Also test `--verbose', `--defines' and `--name-prefix'.
21332 2000-10-02 Akim Demaille <akim@epita.fr>
21334 Improve the readability of the produced parsers.
21336 * src/bison.s1: Formatting changes.
21337 Improve the comment related to the `$' mark.
21338 (yydefault): Don't fall through to `yyresume': `goto' there.
21339 * src/output.c (output_parser): When the `$' is met, skip the end
21341 New variable, `number_of_dollar_signs', to check there's exactly
21342 one `$' in the parser skeleton.
21344 2000-10-02 Akim Demaille <akim@epita.fr>
21346 * lib/xstrdup.c: New file, from the fileutils.
21347 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
21348 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
21349 instead of strlen + xmalloc + strcpy.
21350 * src/symtab.c (copys): Remove, use xstrdup instead.
21352 2000-10-02 Akim Demaille <akim@epita.fr>
21354 * src/gram.h (associativity): New enum type which replaces the
21355 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
21356 `right_assoc', `left_assoc' and `non_assoc'.
21357 Adjust all dependencies.
21358 * src/reader.c: Formatting changes.
21359 (LTYPESTR): Don't define it, use it as a literal in
21360 `reader_output_yylsp'.
21361 * src/symtab.h (symbol_class): New enum type which replaces the
21362 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
21363 `sunknown', `stoken and `snterm'.
21365 2000-10-02 Akim Demaille <akim@epita.fr>
21367 * src/getargs.c (fixed_outfiles): Rename as...
21368 (yaccflag): for consistency and accuracy.
21369 Adjust dependencies.
21371 2000-10-02 Akim Demaille <akim@epita.fr>
21373 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21374 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21375 difficult and introduced a lot of core dump. It turns out that
21376 Bison used an implementation of `xmalloc' based on `calloc', and
21377 at various places it does depend upon the initialization to 0. I
21378 have not tried to isolate the pertinent places, and all the former
21379 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
21380 someone should address this issue.
21382 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
21383 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

21393 * src/system.h: Include `assert.h'.
21395 2000-10-02 Akim Demaille <akim@epita.fr>
21397 * src/state.h (nstates, final_state, first_state, first_shift)
21398 (first_reduction): Move their exportation from here...
21399 * src/LR0.h: to here.
21400 Adjust dependencies.
21401 * src/getargs.c (statisticsflag): New variable.
21402 Add support for `--statistics'.
21403 Adjust dependencies.
21405 Remove a lot of now useless `extern' statements in most files.

21434 * src/nullable.c: Formatting changes.

21438 * src/reduce.h: New file.
21439 Propagate its inclusion.
21440 * src/reduce.c: Topological sort and other formatting changes.
21441 (bool, TRUE, FALSE): Move their definition to...
21442 * src/system.h: here.
21444 2000-10-02 Akim Demaille <akim@epita.fr>
21446 * src/files.c: Formatting changes.
21447 (tryopen, tryclose, openfiles): Rename as...
21448 (xfopen, xfclose, open_files): this.
21449 (stringappend): static.
21450 * src/files.h: Complete the list of exported symbols.

21473 * src/lalr.c: Formatting changes, topological sorting etc.
21475 2000-10-02 Akim Demaille <akim@epita.fr>
21477 * src/output.c (token_actions): Introduce a temporary array,
21478 YYDEFACT, that makes it possible for this function to use
21479 output_short_table.
21481 2000-10-02 Akim Demaille <akim@epita.fr>
21483 `user_toknums' is output as a `short[]' in `output.c', while it is
21484 defined as a `int[]' in `reader.c'. For consistency with the
21485 other output tables, `user_toknums' is now defined as a table of

21529 * src/system.h: Define PARAMS.

21531 purpose of config.h. system.h must not try to fix wrong
21532 definitions in config.h.
21534 2000-09-20 Akim Demaille <akim@epita.fr>
21536 * src/derives.h: New file.

21751 There is now a pseudo variable @$ (readble and writable), location
21752 of the lhs of the rule (by default ranging from the location of

21789 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

22482 an invalid character. Do not abort.
22483 (read_declarations, copy_guard, copy_action): Use
22484 printable_version to avoid unprintable characters in printed output.

22513 always contain the token. This includes growing the token
22514 buffer while reading an integer.
22515 (parse_percent_token): Replaced if-else statement with percent_table.
22516 (parse_percent_token): Added % declarations as another
22517 way to specify the flags -n, -l, and -r. Also added hooks for
22518 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
22519 major changes to files.c.
22520 (lex) Retain in the incoming stream a character following
