6 * tests/Makefile.am ($(TESTSUITE)): Qualify package.m4 in
7 this dependency list as in package.m4's target rule.

21 * HACKING (Announce): RELEASE_TYPE=major must now be written
24 2010-03-20 Joel E. Denny <jdenny@ces.clemson.edu>
27 * NEWS (2.4.2): Set version and date. For the recent test suite
28 portability fixes, don't be so optimistic about their success
29 given the lack of feedback on the affected platforms.
31 2010-02-22 Joel E. Denny <jdenny@ces.clemson.edu>
33 Prepare for 2.4.2 release.
34 * NEWS (2.4.1b): Rename back to...
35 (2.4.2): ... this, and unset date.
36 * configure.ac (AM_INIT_AUTOMAKE): Re-enable gnits.
38 2010-02-22 Joel E. Denny <jdenny@ces.clemson.edu>
41 * NEWS (2.4.2): Rename to...
42 (2.4.1b): ... this for now. Set date.
43 * configure.ac (AM_INIT_AUTOMAKE): Disable gnits for now because
44 it does not like this version name.
46 2010-02-22 Joel E. Denny <jdenny@ces.clemson.edu>
48 tests: fix maintainer-xml-check for recent changes.
49 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Use
50 AT_BISON_CHECK_NO_XML rather than AT_BISON_CHECK because an
51 output file whose name conflicts with a previous output file
52 is now never generated.
54 2010-02-22 Joel E. Denny <jdenny@ces.clemson.edu>
56 portability: fix several issues with M4 subprocess.
58 M4's output pipe was not being drained upon fatal errors during
59 scan_skel. As a result, broken-pipe messages from M4 were seen
60 on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
61 failure in the test suite. The problem was that, on platforms
62 where the default disposition for SIGPIPE is ignore instead of
63 terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
64 then reported it. However, there's some sort of race condition,
65 because the new test group occasionally succeeded.
66 Reported by Albert Chin at
67 <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.
69 There were also problems with the test suite livelocking on
70 Tru64 5.1b. Reported by Didier Godefroy at
71 <http://lists.gnu.org/archive/html/bug-bison/2009-05/msg00005.html>.
72 Switching to create_pipe_bidi suggested by Akim Demaille.
74 To attempt to solve both of these problems, switch to gnulib's
75 create_pipe_bidi and register M4 process as a slave. Along the
76 way, clean up file name conflict handling, which was affected by
77 the broken-pipe problem before the switch.
78 * NEWS (2.4.2): Document.
79 * THANKS (Didier Godefroy): Add.
80 * bootstrap.conf (gnulib_modules): Add pipe.
81 * gnulib: Update to latest to make sure we have all the latest
83 * lib/Makefile.am (libbison_a_SOURCES): Remove subpipe.h and
85 * po/POTFILES.in (lib/subpipe.c): Remove.
86 * src/files.c (compute_output_file_names): Update invocations
87 of output_file_name_check.
88 (output_file_name_check): In the case that the grammar file
89 would be overwritten, use complain instead of fatal, but replace
90 the output file name with /dev/null. Use the /dev/null solution
91 for the case of two conflicting output files as well because it
92 seems safer in case Bison one day tries to open both files at
94 * src/files.h (output_file_name_check): Update prototype.
95 * src/output.c (output_skeleton): Use create_pipe_bidi and
96 wait_subprocess. Assert that scan_skel completely drains the
98 * src/scan-skel.l (at_directive_perform): Update
99 output_file_name_check invocation.
100 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Check that the
101 grammar file actually isn't overwritten.
102 (Conflicting output files: -o foo.y): Update expected output.
103 * tests/skeletons.at (Fatal errors but M4 continues producing
104 output): New test group.
106 2010-02-04 Joel E. Denny <jdenny@ces.clemson.edu>
109 * HACKING (Release Procedure): Add reminder about keeping
110 POTFILES files up-to-date.

113 2010-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
115 tests: link lib/libbison.a for gnulib.
116 This solves a problem on Solaris 2.7 where the testsuite needs
117 at least gnulib's rpl_fopen. Reported by Albert Chin at
118 <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00001.html>.

130 2010-01-22 Joel E. Denny <jdenny@ces.clemson.edu>
132 Version 2.4.1a delayed.
133 * NEWS (2.4.1a): Increment release date as there has been a
134 small delay in getting the announcements and tarballs out.

293 Avoid compiler warning.
295 2009-08-27 Joel E. Denny <jdenny@clemson.edu>
297 tests: use perl for printing special sequences to files.
298 And skip tests if perl is not available. This is better than
299 playing tricks with shell portability. Suggested by Akim

328 Discussed starting at

330 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
331 For a \0 and similar escape sequences meaning the null
332 character, report an invalid escape sequence instead of an
333 invalid null character because the latter does not actually
334 appear in the user's input.
335 In all escape sequence complaints, don't escape the initial
336 backslash, and don't quote when the sequence appears at the end
337 of the complaint line unless there's whitespace that quotearg
339 Consistently say "invalid" not "unrecognized".

361 build: lower gettext requirements.
363 Bison was uselessly requiring the formatstring macros from

455 the Flex manual, but which Flex has supported since at least as
456 far back as 2.5.4. However, if any of our developers still use

1156 * NEWS (2.3b+): Rename to...
1157 (?.?): ... this because we're dropping the "+" version naming scheme,
1158 but, in general, we still can't be sure of our next release name.
1159 * bootstrap: Add a quick hack to remove from .gitignore the
1160 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
1161 entry. This should really be fixed in gnulib instead.
1162 * bootstrap.conf (gnulib_modules): Add gnumakefile.
1163 * configure.ac (AC_INIT): Set version name by invoking

1194 Fix some .gitignore and .cvsignore problems.
1195 * bootstrap (insert_sorted_if_absent): Replace all uses with...
1196 (insert_vc_ignore): ... this new function, which prepends `/' to all
1197 .gitignore entries before passing them to insert_sorted_if_absent.
1198 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
1199 .cvsignore files are maintained even though Bison developers run
1200 bootstrap while using Git.
1201 * .cvsignore (*.patch *.log log patches applied): Remove, apparently

1221 the first argument because it may become position-dependent, and unset
1222 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
1223 Add comments explaining these issues in more detail.
1225 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

1309 Update to the current gnulib CVS repository, and fix trigraph handling
1311 * bootstrap: Update gnulib CVS repository URL.
1312 (symlink_to_dir): Encapsulate the code that guarantees the destination
1313 directory exists into...
1314 (check_dst_dir): ... this new function, and...
1315 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
1316 fail when copying files into lib/uniwidth/.
1317 * src/output.c (prepare_symbols): When writing yytname muscles, where
1318 symbol names will be encoded in C-string literals, tell quotearg to
1319 escape trigraphs. This used to be the default in gnulib.
1320 * tests/regression.at (Token definitions): Because of the change in
1321 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
1322 escapes trigraphs in symbol names. Thus, yytname no longer has
1323 trigraphs unnecessarily doubly escaped. Update test case output.
1324 Extend test case to be sure Bison's own error messages will no longer
1325 have trigraphs in symbol names unnecessarily escaped once.

1340 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
1341 consistency. Update the -g and -x entries now that they take
1342 arguments. Use brackets to indicate optional arguments.
1343 * src/getargs.c (usage): Explain the relationship between arguments of
1344 long and short options more completely. Document --defines and -d
1345 separately since the former takes an argument but, for POSIX Yacc, the
1347 (short_options): Let -W take an optional argument like --warnings.

1365 Fix the handling of $opt which resulted in all the argument to be
1366 considered as optional.

1404 * data/yacc.c: Clean up whitespace in the output a little.
1405 (yypstate_allocated): Define for impure push parsers regardless of
1406 whether the pull interface is also requested.
1407 * tests/push.at (Push Parsing: Multiple impure instances): Extend to
1408 check impure push parsers without the pull interface.
1410 * data/yacc.c (yypstate_new): Don't try to invoke yyerror since

2047 * data/bison.m4 (b4_cat): New.
2048 (b4_error, b4_error_at): Use b4_cat to send error directives directly

2050 comments and add examples.
2051 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
2053 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately

2056 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
2057 instead of just in them. Recognize @\n in both places. Both expand to

2100 %define variable push_pull.
2101 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
2102 parsing requests here...
2103 * data/yacc.c: ... hack this to switch to push.c any time
2104 b4_use_push_pull_flag or the %define variable push_pull is set. This
2105 will go away when we mv push.c yacc.c.
2106 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
2107 push parsing is not supported since unused %define variables are
2109 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
2110 * src/muscle_tab.h (muscle_percent_define_check_values): Update

2153 local variable `sep'.
2155 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
2157 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
2159 * src/print-xml.c: Prefer "const" after types; that's more consistent.
2160 (xml_printf): Indent just 1 space for level.
2161 (e_char, xlate_char): Remove.
2162 (xml_escape_string): Rewrite to avoid undefined behavior (used
2163 storage that was freed from the stack).

2215 2006-08-18 Paul Eggert <eggert@cs.ucla.edu>
2216 Bruno Haible <bruno@clisp.org>
2218 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists
2219 and is a script that invokes bison. Tighten the code. Add comments.
2221 2007-08-28 Joel E. Denny <jdenny@ces.clemson.edu>

2233 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
2235 In impure push mode, don't allow more than one yypstate to be allocated
2236 since multiple impure parsers would corrupt yynerrs.
2237 * data/push.c (yypstate_allocated): New static global variable
2239 (yypull_parse): If yypstate_new returns 0, don't report it as memory
2240 exhaustion if yypstate_allocated is 1, but still return 2.
2241 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
2242 already 1. Otherwise, set it to 1.
2243 (yypstate_delete): Set it to 0.

2318 Get rid of broken %no-parser, -n, and --no-parser implementation and
2320 * TODO: Don't mention them.
2321 * doc/bison.1: Likewise.
2322 * doc/bison.texinfo (Decl Summary): Likewise.
2323 (Bison Options): Likewise.
2324 (Option Cross Key): Likewise.
2325 * src/getargs.c (no_parser_flag): Remove global variable.
2326 (usage): Don't print description of -n and --no-parser.
2327 (long_options): Remove --no-parser entry here.
2328 (getargs): Remove -n case in the switch here.
2329 * src/getargs.h (no_parser_flag): Remove extern.
2330 * tests/regression.at (Web2c Actions): Remove comment that mentions
2333 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
2335 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
2336 name user variables starting with `yy'. Just pass NULL instead of a
2337 dummy local &yylval to yypush_parse.
2338 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
2341 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
2343 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
2344 true since it's then always used regardless of whether yyoverflow is
2345 defined. Reported by Christian Burger at
2346 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
2347 * THANKS: Add Christian Burger.
2349 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
2350 node names: say "Decl Summary" not "Bison Declaration Summary".
2352 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
2354 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
2355 determine whether this function has already complained about an invalid
2356 value for a %define boolean variable, don't check whether Bison has
2357 ever examined the value. As written, the check was a tautology.
2358 Instead, record and check for this complaint using a separate muscle.
2360 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
2362 Fix push parsing memory leak reported by Brandon Lucia at
2363 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
2364 * THANKS: Add Brandon Lucia.
2365 * data/push.c (yypstate_delete): Free the stack if it was reallocated
2366 but the parse never completed and thus freed it.
2367 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
2368 * tests/testsuite.at: Include push.at.
2369 * test/push.at: New.
2370 (Push Parsing: Memory Leak for Early Deletion): New test case.
2372 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
2374 Improve handling of multiple S/R conflicts in the same state and of S/R
2375 conflicts involving multiple reductions.
2376 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
2377 set for a state here or Bison will abort if it is reassigned on a
2378 later conflicted reduction in the same state.
2379 Similarly, don't finalize and assign the solved conflicts report here
2380 or it will be lost if it is reassigned on a later conflicted reduction
2382 (set_conflicts): Instead, assign them both here after all S/R conflicts
2383 in the state have been fully examined.
2384 * src/print.c (shift_set): Rename to...
2385 (no_reduce_set): ... this.
2386 (print_reductions): Update for rename, and add %nonassoc error action
2387 tokens to no_reduce_set so that, when printing the first remaining
2388 reduction on an error action token, the reduction is enclosed in
2390 (print_results): Update for rename.
2391 * tests/conflicts.at (Solved conflicts report for multiple reductions
2392 in a state): New test case.
2393 (%nonassoc error actions for multiple reductions in a state): New test
2396 * src/main.c (main): Don't depend on C99 features.
2398 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
2400 * build-aux/.cvsignore: Add compile.
2401 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
2404 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
2406 * bootstrap (slurp): Create target directories that don't exist.
2407 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
2409 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
2411 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
2413 * closure.c (closure): Likewise.
2414 * state.h (reductions): Comment sorting of rules.
2415 (state): Comment sorting of items.
2417 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
2419 Fix C++ test cases after recent Gnulib changes. Discussed starting at
2420 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
2421 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
2422 definition in order to avoid Gnulib headers since we don't use config.h
2424 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
2425 rather than AT_DATA so that config.h is included.
2427 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
2429 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
2430 instead of fprintf. Guard these functions with #if YYDEBUG instead of
2431 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
2432 and so that YYFPRINTF is guaranteed to be defined here.
2434 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
2436 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
2438 (muscle_percent_define_check_values): ... this more helpful function.
2439 Again, it's not used yet, but it will be.
2440 * src/muscle_tab.h: Likewise.
2442 Improve some comments in parser table construction.
2443 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
2444 (generate_states): Don't mention ruleset, which is internal to closure.
2445 * src/closure.c (closure): Explain sorting of core and itemset, which
2446 is required for this function to behave correctly.
2447 * src/closure.h (closure): Mention sorting.
2449 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
2451 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2452 move the check for disabled transitions to an aver since conflict
2453 resolution hasn't happened yet.
2455 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
2456 labels a state as inconsistent just because it has error transitions.
2457 The original form of this check appeared in revision 1.1 of lalr.c,
2458 which was committed on 1991-12-21. Now (at least), changing the
2459 consistency label on such a state appears to have no useful effect in
2460 any of the places it is examined, which I enumerate below. The key
2461 point to understanding each item in this enumeration is that a state
2462 with an error transition is labelled consistent in the first place only
2463 if it has no rules, so the check cannot matter for states that have
2464 rules. (1) Labelling a state as inconsistent will cause set_conflicts
2465 to try to identify its conflicts, and a state must have *rules* to have
2466 conflicts. (2) Labelling a state as inconsistent will affect how
2467 action_row sets the default *rule* for the state. (3) Labelling a
2468 state as inconsistent will cause build_relations to add lookback edges
2469 to *rules* in that state.
2470 * src/state.h (struct state): Word the comment for member consistent
2473 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
2475 Don't depend on C99 features.
2476 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.

2480 (state_remove_unreachable_states): Fix for-loop.
2482 Don't widen struct state with member reachable just to temporarily
2483 record reachability. Instead, use a local bitset.
2484 * src/state.h (struct state): Remove member.
2485 * src/state.c (state_new): Don't initialize it.
2486 (state_mark_reachable_states): Rename to...
2487 (state_record_reachable_states): ... this, and use bitset.
2488 (state_remove_unreachable_states): Use bitset.

2496 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
2497 the case of pure parsers. Reported by Frans Englich at
2498 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
2499 * THANKS: Add Frans Englich.

2561 Minor code cleanup in parser table construction.
2562 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
2563 (new_itemsets, save_reductions): Update for rename to nitemset.
2564 * src/closure.c (nritemset): Rename to...

2656 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
2657 Bison uses of names rather than just skeleton uses of names.
2658 (b4_percent_define_get, b4_percent_define_ifdef): Rename

2702 * data/lalr1.java: Prefix all private members with yy.
2704 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
2706 Use YYFPRINTF instead of fprintf where appropriate. Reported by
2707 Sebastien Fricker at

2724 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
2726 Undo my 2007-02-07 change, switching back to the c-strcase module
2727 introduced in the 2007-02-03 change. Bruno Haible reported that
2728 the 2007-02-07 change would be dangerous in Turkish if we add a
2729 language whose name contains "i", since "i" is not lowercase "I"
2731 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
2732 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
2733 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
2734 * m4/.cvsignore: Remove strcase.m4.
2735 * src/getargs.c: Revert 2007-02-07 change, as follows.
2736 Include c-strcase.h.
2737 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
2739 2007-02-11 Bruno Haible <bruno@clisp.org>
2741 Enable the Java related testsuite tests when the only Java compiler
2742 found is a gcj < 4.3. Discussed at
2743 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
2744 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
2746 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
2748 * data/Makefile.am: Update copyright date.
2749 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
2750 yypstate_new returns NULL.
2751 (yypstate_new): Return NULL if malloc does.
2752 * src/reader.c (packgram): Move translation of rule actions from the
2753 beginning of packgram to...
2754 (check_and_convert_grammar): ... here right before packgram is invoked
2755 so it's easier to write more complete comments, and remove redundant
2758 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
2760 As in semantic actions, make @$ in %initial-action, %destructor, and
2761 %printer imply %locations.
2762 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
2764 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
2765 (@$ in %initial-action implies %locations,
2766 @$ in %destructor implies %locations,
2767 @$ in %printer implies %locations): ... these new test cases.
2769 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
2771 Undo most of the 2007-02-03 change, switching to the strcase module
2772 now that gnulib strcase has been fixed.
2773 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
2774 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
2775 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
2776 * m4/.cvsignore: Add strcase.m4.
2777 * src/getargs.c: Revert 2007-02-03 change, as follows.
2778 Don't include c-strcase.h.
2779 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
2780 strcasecmp has "unspecified behavior" outside the POSIX locale,
2781 but it works fine in practice if at least one argument is ASCII,
2782 as is the case in Bison.
2784 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
2786 * tests/java.at: Skip tests if only one of javac/java is present.
2787 Reported by Joel E. Denny.
2788 * tests/atlocal.in: Adjust copyright years.
2790 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
2792 * data/lalr1.java (Stack): Work around old verifiers that disallow
2793 access to the private fields of an inner class, from the outer class.
2794 We can make Stack's fields public because user code doesn't have access
2795 to the instance of Stack used by parse(). Reported by Paul Eggert.
2797 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
2799 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
2800 the right spot for these files?
2801 * bootstrap.conf (gnulib_modules): Add c-strcase.
2802 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
2804 * src/getargs.c: Include c-strcase.h.
2805 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
2806 to avoid unspecified behavior.
2808 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
2810 * doc/bison.texinfo (Decl Summary): Correct typo.
2812 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
2814 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
2815 Complain if the value does not match empty, "true" or "false".
2816 * data/c++.m4: Adjust default definitions of %define variables.
2817 * data/java.m4: Adjust default definitions of %define variables.
2818 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
2820 * tests/input.at (Boolean %define variables): Test new behavior.

2831 * data/java.m4: New.
2832 * data/lalr1.java: New.
2834 * doc/bison.texinfo: Put "A Complete C++ Example" under
2835 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
2836 under Other Languages.
2838 * src/getargs.c (valid_languages): Add Java.
2839 * src/getargs.h (struct bison_language): Update size of string fields.
2841 * tests/Makefile.am: Add java.at.
2842 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
2843 * tests/java.at: New.
2844 * tests/testsuite.at: Include it.
2846 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
2849 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
2850 at_directive_argv arguments so these no longer have to be global
2851 variables. Also, update the implementation for the following changes.
2852 (fail_for_at_directive_too_many_args,
2853 fail_for_at_directive_too_few_args): Add at_directive_name argument.
2854 (at_directive_name): Remove as at_directive_argv[0] will be used for
2856 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
2857 for the directive name.
2858 (at_directive_argc, at_directive_argv): Make these local within
2859 skel_lex instead of global.
2860 (INITIAL): Update directive start action for above changes.
2861 (SC_AT_DIRECTIVE_ARG): Rename to...
2862 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
2863 (SC_AT_DIRECTIVE_SKIP_WS): Update.
2864 (scan_skel): Move yylex_destroy to...
2865 (skel_scanner_free): ... here.
2866 * tests/skeletons.at (installed skeleton file name): Rename to...
2867 (installed skeleton file names): ... this.
2869 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
2871 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
2872 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
2873 Summary" not "Directives".
2874 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
2875 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
2876 since the former is now the more complete one.
2877 (Prologue Alternatives): Likewise and do the same for %defines.
2878 (Table of Symbols): Add summary of %code, add summary of %define, and
2879 move full %code documentation to...
2880 (Decl Summary): ... here for consistency with other entries in these
2882 Move %define entry in order to keep this list alphabetized.
2883 Reword %define entry a little to put less emphasis on the skeleton
2884 concept, which most users shouldn't have to think about.
2886 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
2888 Adjust to recent gnulib changes.
2889 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
2890 Add string.h, string_.h, unistd_.h, wchar_.h.
2891 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
2892 * src/system.h: Don't include <stpcpy.h>; this is now done by
2895 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
2897 Simplify implementation of unqualified %code, implement macros for
2898 uniform treatment of boolean %define flags. Document %define.
2899 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
2900 b4_percent_code_ifdef): New.
2901 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
2902 * data/c++.m4: Define default value for global_tokens_and_yystype.
2903 * data/glr.cc: Likewise.
2904 * data/location.cc: Use b4_percent_define_flag_if.
2906 * doc/bison.texinfo (Decl Summary): Document %define.
2908 * src/parse-gram.y (Unqualified %code): Change muscle name to
2910 (content.opt): Default to empty.
2912 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
2914 Implement support for relative and absolute skeleton file names.
2915 Discussed starting at
2916 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
2917 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
2918 (Bison Options): Document in --skeleton entry.
2919 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
2920 full_skeleton can't necessarily hold all of pkgdatadir.
2921 If the specified skeleton file name contains a `/', don't prepend
2923 * src/parse-gram.y (prologue_declaration): If the specified skeleton
2924 file name contains a `/', prepend the grammar file directory.
2925 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
2926 * skeletons.at: New file.
2927 (relative skeleton file names): New test case.
2928 (installed skeleton file names): New test case.
2929 * tests/testsuite.at: Include skeletons.at.
2931 * bootstrap: Update copyright to 2007.
2933 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
2935 * bootstrap: Remove occurrences of .#bootmp from the files.
2937 2007-01-17 Akim Demaille <akim@epita.fr>
2939 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
2941 Use per-type %printer.
2943 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
2945 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

2953 2007-01-16 Akim Demaille <akim@epita.fr>
2955 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
2957 (Calc++ Scanner): Exit with failure if we can't open the input
2959 Accept "-" standing for stdin.
2960 (Calc++ Top Level): Print the result only if the parsing was
2963 2007-01-16 Akim Demaille <akim@epita.fr>
2965 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
2967 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
2968 and Joel E. Denny <jdenny@ces.clemson.edu>
2970 Clean up %define and %code implementation in M4 some. Most
2971 importantly, rename all related macros to be in the b4_percent_define
2972 and b4_percent_code namespaces. Also, complete support for `.' in
2973 %define variable names and %code qualifiers.
2974 * data/bison.m4 (b4_check_user_names): Check for special
2975 "SKELETON-NAMESPACE(name)" macros instead of using two nested
2977 (b4_get_percent_define, b4_get_percent_code): Rename to...
2978 (b4_percent_define_get, b4_percent_code_get): ... these.
2979 Extend documentation with examples.
2980 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
2981 b4_percent_define_skeleton_variables and
2982 b4_percent_code_skeleton_qualifiers.
2983 Expect any value for the %define variable `foo' to be stored in the
2984 macro named `b4_percent_define(foo)'; expect any %code blocks for the
2985 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
2986 expect any unqualified %code blocks to be stored in a macro named
2987 `b4_percent_code_unqualified'.
2988 Use m4_indir so that %define variable names and %code qualifiers can
2989 contain `.', which is allowed by the grammar parser.
2990 (b4_percent_define_default): New macro to set a default value for a
2992 (m4_wrap): Update wrapped code, and fix some underquoting.
2993 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
2994 Expect grammar uses of %define variables and %code qualifiers to be
2995 defined in b4_percent_define_user_variables and
2996 b4_percent_code_user_qualifiers.
2997 * data/c++.m4: Use b4_percent_define_default rather than
2998 m4_define_default. Fix some underquoting. Skeleton usage of %define
2999 variable define_location_comparison now implies skeleton usage of
3000 %define variable filename_type.
3001 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
3002 data/push.c, data/yacc.c: Update macro names.
3003 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
3006 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
3008 DJGPP specific issues.
3010 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
3011 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
3013 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3015 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
3016 run parsers in all tests so that Valgrind is invoked during
3017 maintainer-check-valgrind.
3018 (Duplicate representation of merged trees): Free all semantic values.
3019 (Duplicated user destructor for lookahead): Likewise.
3021 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3023 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
3024 command-line prefix.
3025 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
3026 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
3027 miss Valgrind messages.
3028 (Exploding the Stack Size with Malloc): Likewise.
3030 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3032 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
3033 locals. Reported by Juan Manuel Guerrero at
3034 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
3035 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
3036 Fix some indentation also.
3037 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
3038 explaining this issue.
3040 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
3041 and Joel E. Denny <jdenny@ces.clemson.edu>
3043 Simplify union and prologue handling, and escape union and lex/parse
3044 params with digraphs.
3045 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
3046 values to the empty string since these are no longer guaranteed
3047 initialized by the front-end.
3048 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
3049 braces around b4_user_stype since this is no longer done by the
3051 * src/files.c, src/files.h (pre_prologue_obstack,
3052 post_prologue_obstack): Remove.
3053 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
3054 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
3055 with digraphs. This fixes lex params and parse params.
3056 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
3057 * src/output.c (prepare): Remove muscle insertion of the prologues.
3058 (output): Remove freeing of pre_prologue_obstack and
3059 post_prologue_obstack.
3060 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
3061 than prologue_augment for prologue parsing so you don't need prologue
3063 (grammar_declaration): For %union RHS, use `braceless' instead of
3064 "{...}" so that braces are already stripped and code is escaped with
3066 * src/reader.c (prologue_augment): Remove.
3067 (reader): Remove initialization of pre_prologue_obstack and
3068 post_prologue_obstack.
3069 * src/reader.h (prologue_augment): Remove.
3071 * data/c.m4: Remove stray parenthesis.
3073 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3075 Remove quotes from variables names in %define directives and from
3076 qualifiers in %code directives, and restrict the characters that are
3077 allowed in them to M4-friendly ones. For %define, continue to support
3078 the quoted form as a deprecated feature. Discussed starting at
3079 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
3080 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
3082 * doc/bison.texinfo (Prologue Alternatives): Update.
3083 (Decl Summary): In %defines entry, update mention of `%code requires'
3084 and `%code provides'.
3085 (C++ Location Values): Update %define uses.
3086 (Calc++ Parser Interface): Likewise.
3087 (Calc++ Parser): Likewise, and update `%code requires' uses.
3088 (Table of Symbols): Update %code documentation.
3089 * src/parse-gram.y (prologue_declaration): For %define variables, use
3090 `variable' instead of `STRING'.
3091 (grammar_declaration): For %code qualifiers, use `ID' instead of
3093 (variable): New nonterminal that takes an `ID' or a `STRING'.
3094 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
3096 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
3097 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
3098 (%define errors): Update %define uses.
3100 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3102 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
3103 instead of muscle_insert for %define values so that M4-special
3104 characters are replaced with digraphs.
3105 * tests/input.at (%define errors): Extend to check weird values.
3107 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3109 Instead of having skeletons declare all valid %define variables and
3110 %code qualifiers, provide macros that retrieve the associated values
3111 and build these lists automatically. Thus Bison will now warn when a
3112 variable or qualifier is not used by the skeleton in the current
3113 invocation regardless of whether it might sometimes be used by that
3114 skeleton in other invocations. Also, move all %define value macros to
3115 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
3116 form, which is replaced by %code.
3117 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
3118 (b4_check_user_names): ... this, and change the series of valid name
3119 arguments to a single list argument for names used in the skeleton
3120 similar to the existing list argument for names used in the grammar.
3121 Warn instead of complaining.
3122 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
3123 values and %code code, to format %code code properly, and to build
3124 lists of all %define variables and %code qualifiers used in the
3125 skeleton: b4_skeleton_percent_define_variables and
3126 b4_skeleton_percent_code_qualifiers.
3127 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
3129 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
3130 the skeleton names lists can finish building first. In place of
3131 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
3132 expect the lists b4_user_percent_define_variables and
3133 b4_user_percent_code_qualifiers.
3134 * data/c++.m4: Where setting default values for b4_parser_class_name,
3135 b4_location_type, b4_filename_type, b4_namespace, and
3136 b4_define_location_comparison, update their names to the
3137 b4_percent_define_ namespace.
3138 * data/glr.c: Don't use b4_check_percent_define_variables and
3139 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
3140 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
3141 (b4_parser_class_name, b4_namespace): Define these using
3142 b4_get_percent_define for parser_class_name and namespace.
3143 * data/location.cc: Use b4_get_percent_define.
3144 * data/push.c: Don't use b4_check_percent_define_variables and
3145 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
3146 * data/yacc.c: Likewise, and don't call m4_exit in
3147 b4_use_push_for_pull_if or m4_wrap code will never execute.
3148 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
3150 (muscle_grow_user_name_list): ... this for consistency with the
3151 terminology used in bison.m4.
3152 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
3153 %define variable names, and rename muscle used_percent_define_variables
3154 to user_percent_define_variables.
3155 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
3156 user_percent_code_qualifiers.
3158 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
3159 {CODE} form is no longer accepted.
3160 * tests/input.at (Reject bad %code qualifiers): Rename to...
3161 (Reject unused %code qualifiers): ... this, and update test output.
3162 (%define error): Update test output.
3164 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
3166 Check for unrecognized %define variables similar to checking for
3167 unrecognized %code qualifiers. Check for redefined %define variables.
3168 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
3170 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
3171 (b4_check_percent_define_variables): New, also wraps it.
3172 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
3173 variables using b4_check_percent_define_variables.
3174 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
3175 all those exercised in the test suite and all those listed in the
3176 `Default values' section of c++.m4. Are there others?
3177 * data/push.c, data/yacc.c: Declare no valid %define variables.
3178 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
3179 similar to muscle_find, but it works even when the muscle stores a
3181 (muscle_grow_used_name_list): New function for constructing the used
3182 name list muscles that b4_check_for_unrecognized_names requires.
3183 * src/parse-gram.y (prologue_declaration): Warn if a variable is
3184 %define'd more than once. Define the b4_used_percent_define_variables
3185 muscle with muscle_grow_used_name_list.
3186 (grammar_declaration): Abbreviate %code code with
3187 muscle_grow_used_name_list.
3188 * tests/input.at (%define errors): New.
3190 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3192 Provide warn_at, complain_at, and fatal_at function callbacks to the
3193 skeletons, and use this for %code qualifier complaints.
3194 * data/bison.m4 (b4_error_at): New, invoked by...
3195 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
3196 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
3197 @fatal_at(...@) directives.
3198 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
3199 qualifiers in b4_used_percent_code_qualifiers and to use
3201 * src/location.c, src/location.h (boundary_set_from_string): New global
3203 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
3205 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
3206 to b4_used_percent_code_qualifiers.
3207 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
3209 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
3210 (lineno): Rename to...
3211 (out_lineno): ... this so I don't misunderstand it again.
3212 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
3213 here; these newlines are in the input but not the output file.
3214 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
3215 (at_directive_perform): ... this new static function, and add handling
3216 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
3218 * tests/input.at (Reject bad %code qualifiers): Update test output with
3219 locations and extend.
3221 * tests/output.at (Output file name: [, Output file name: ]): Remove
3222 bogus comment about these tests failing.
3224 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3226 Clean up b4_check_percent_code_qualifiers a little.
3227 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
3228 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
3229 documentation and add examples.
3230 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
3233 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
3235 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
3236 unreliable -- especially when they're hidden inside another macro.
3237 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
3238 data/c.m4: Remove m4_divert(-1).
3239 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
3240 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
3241 m4_divert_push(0) and m4_divert_pop(0).
3242 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
3243 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
3244 pushed and popped by m4sugar, should be first on the stack.
3246 Provide warn, complain, and fatal function callbacks to the skeletons.
3247 This provides more flexibility than m4_fatal, improves the error
3248 message format, and captures messages for translation. Discussed
3250 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
3251 * data/bison.m4 (b4_error): New, invoked by...
3252 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
3253 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
3254 directives. Because these M4 macros might be called when the current
3255 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
3256 the previous removal of uses of m4_divert, which caused trouble.
3257 (b4_check_percent_code_qualifiers): Use b4_complain instead of
3258 m4_fatal to report unrecognized %code qualifiers.
3259 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
3260 push parser requests.
3261 * data/glr.c: Use b4_complain instead of m4_fatal to report
3262 non-deterministic push parser requests.
3263 Update @output usage to @output(...@) form.
3264 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
3265 report missing %defines. Update @output usage to @output(...@) form.
3266 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
3268 * src/main.c (main): Invoke skel_scanner_free.
3269 * src/scan-skel.h (skel_scanner_free): Prototype new function.
3270 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
3271 obstack_for_string from flex-scanner.h.
3272 (YY_DECL): Use to declare skel_lex static.
3273 (decode_at_digraphs): Remove; now handled in the new
3274 SC_AT_DIRECTIVE_ARG start condition.
3275 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
3277 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
3278 at_directive_argv): New static globals.
3279 (INITIAL): Use fail_for_invalid_at.
3280 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
3281 recognize the start of a generalized `@directive(...@)' form and
3283 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
3284 directive args (using the new obstack_for_string), to decode the
3285 contained @ diagraphs, and to perform the directive. It recognizes
3286 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
3288 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
3289 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
3291 (scan_skel): Initialize obstack_for_string on the first call.
3292 (skel_scanner_free): New function to free obstack_for_string.
3293 * tests/input.at (Reject bad %code qualifiers): Update test output.
3295 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
3297 Consolidate the 4 prologue alternative directives (%code, %requires,
3298 %provides, and %code-top) into a single %code directive with an
3299 optional qualifier field. Discussed at
3300 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
3301 * NEWS (2.3a+): Rewrite the existing entry for the prologue
3303 * doc/bison.texinfo (Prologue Alternatives): Update.
3304 (Decl Summary): Update to %code "requires" and %code "provides".
3305 (Calc++ Parser): Update to %code "requires".
3306 (Table of Symbols): Remove entries for %requires, %provides, and
3307 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
3308 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
3309 are replaced by b4_percent_code_provides and b4_percent_code_requires,
3310 which are skeleton-specific.
3311 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
3312 declare what %code qualifiers it supports and to complain if any other
3313 qualifiers were used in the grammar.
3314 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
3315 and b4_user_code([b4_percent_code_provides]) in place of
3316 b4_user_requires and b4_user_provides.
3317 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
3318 Add b4_user_code([b4_percent_code_top]) and
3319 b4_user_code([b4_percent_code]).
3320 Invoke b4_check_percent_code_qualifiers.
3321 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
3322 PERCENT_REQUIRES): Remove.
3323 (grammar_declaration): Remove RHS's for %code-top, %provides, and
3324 %requires. Rewrite the %code RHS as the unqualified form defining the
3325 muscle b4_percent_code. Add another RHS for the qualified %code form,
3326 which defines muscles of the form b4_percent_code_QUALIFIER and the
3327 b4_used_percent_code_qualifiers muscle.
3328 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
3329 PERCENT_REQUIRES): Remove.
3330 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
3331 %code "requires" and %code "provides".
3332 * tests/input.at (Reject bad %code qualifiers): New.
3334 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
3336 Use the new code_props interface for destructors and printers.
3337 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
3338 printer_location members, and change the type of the destructor and
3339 printer members to code_props.
3340 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
3341 symbol_printer_get, semantic_type_destructor_set,
3342 semantic_type_printer_set, default_tagged_destructor_set,
3343 default_tagless_destructor_set, default_tagged_printer_set,
3344 default_tagless_printer_set): Use code_props in arguments and return
3345 types in place of char const * and location.
3346 (symbol_destructor_location_get, symbol_printer_location_get): Remove
3347 since the locations are now contained in the return of
3348 symbol_destructor_get and symbol_printer_get.
3349 * src/output.c (symbol_destructors_output, symbol_printers_output):
3351 (symbol_code_props_output): ... this to eliminate duplicate code.
3352 (output_skeleton): Update to use symbol_code_props_output.
3353 * src/reader.c (symbol_should_be_used): Update use of
3354 symbol_destructor_get.
3355 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
3356 Update uses of the various _destructor_set and _printer_set functions.
3357 * src/symtab.c: (default_tagged_destructor_location,
3358 default_tagless_destructor_location, default_tagged_printer_location,
3359 default_tagless_printer_location): Remove since we...
3360 (default_tagged_destructor, default_tagless_destructor,
3361 default_tagged_printer, default_tagless_printer): ... change the type
3362 of these to code_props.
3363 (symbol_new, semantic_type_new, symbol_destructor_set,
3364 semantic_type_destructor_set, symbol_destructor_get,
3365 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
3366 symbol_check_alias_consistency, default_tagged_destructor_set,
3367 default_tagless_destructor_set, default_tagged_printer_set,
3368 default_tagless_printer_set): Update.
3369 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
3370 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
3372 (symbol_print): Use SYMBOL_CODE_PRINT.
3374 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
3376 Use the new code_props interface for rule actions.
3377 * src/symlist.h (symbol_list): Replace action, action_location, and
3378 used members with a code_props action_props member.
3379 * src/reader.c (symbol_should_be_used, grammar_rule_check,
3380 grammar_midrule_action, grammar_current_rule_merge_set,
3381 grammar_current_rule_symbol_append, packgram): Update.
3382 * src/scan-code.h (translate_rule_action): Remove, no longer used.
3383 * src/scan-code.l (handle_action_dollar): Update.
3384 (translate_rule_action): Remove, no longer used.
3385 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
3387 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3389 Use the new code_props interface in parse-gram.y.
3390 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
3391 Update all uses of translate_* functions to use the new code_props
3392 interface and to use gram_scanner_last_string_free and
3393 code_scanner_last_string_free where possible.
3394 (grammar_declaration): symbol_list_destructor_set and
3395 symbol_list_printer_set now perform the translation, so don't do it
3396 here. Use gram_scanner_last_string_free where possible.
3397 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
3398 translate_code): Remove, no longer used.
3399 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
3400 symbol_list_printer_set): Perform code translation here rather than
3401 depending on the caller to do so.
3403 * src/symlist.h (struct symbol_list): Correct some documentation typos.
3404 * src/scan-gram.h (gram_last_string): Remove declaration.
3405 * src/scan-gram.l (last_string): Declare it static.
3407 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3409 Encapsulate code properties and related functionality for the various
3410 destructors, printers, and actions into a code_props structure and
3411 interface. This patch merely implements code_props in scan-code.h and
3412 scan-code.l. Future patches will rewrite other modules to use it.
3413 Discussed starting at
3414 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
3415 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
3416 consistently initialize const structs that have an empty location
3418 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
3419 to ensure consistency.
3420 * src/scan-code.h (code_props): New structure.
3421 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
3422 function, macro, and const global variable for initializing a
3423 code_props with no code.
3424 (code_props_plain_init, code_props_symbol_action_init,
3425 code_props_rule_action_init, code_props_translate_code): The rest of
3426 the new code_props functional interface. Among other things, the init
3427 functions set the code_props kind field so that
3428 code_props_translate_code will know whether to behave like
3429 translate_symbol_action, translate_rule_action, or translate_code.
3430 These old translate functions must remain until all other modules are
3431 updated to use the new code_props interface.
3432 (code_scanner_last_string_free): New function similar to
3433 gram_scanner_last_string_free.
3434 (code_scanner_free): Add documentation.
3435 * src/scan-code.l: Implement the new interface.
3436 (code_lex): Make it static, add a code_props* argument, and remove the
3438 (last_string): New static global similar to the one in scan-gram.l.
3439 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
3441 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
3442 code_props since Bison may one day use this information for destructors
3444 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
3445 (handle_action_dollar): Use symbol_list_n_get and set used flag
3446 directly since symbol_list_n_used_set is removed.
3447 (translate_action): Add a code_props* argument and remove the rule,
3448 action, and location arguments. Pass the code_props* on to code_lex.
3449 (translate_rule_action, translate_symbol_action, translate_code):
3450 Rewrite as wrappers around the new code_props interface.
3451 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
3452 it would eventually need to break the encapsulation of code_props.
3454 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3456 * etc/.cvsignore: New.
3458 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3460 Add maintainer-push-check to run maintainer-check using push parsing in
3461 place of pull parsing where available.
3462 * Makefile.am (maintainer-push-check): New.
3463 * data/bison.m4 (b4_use_push_for_pull_if): New.
3464 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
3465 appropriately based on their existing values.
3466 (yypush_parse): Don't print push-parser-specific diagnostics if push
3467 parsing is being used in place of pull parsing.
3468 * data/yacc.c: If push parsing should replace pull parsing, redirect to
3470 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
3471 variable, and insert b4_use_push_for_pull_flag into muscles.
3472 * tests/Makefile.am (maintainer-push-check): New.
3474 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3476 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
3477 (whether successful or failed) so that yypush_parse can be invoked
3478 again to start a new parse using the same yypstate.
3479 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
3480 check multiple yypull_parse invocations on the same yypstate. For pull
3481 mode, extend to check multiple yyparse invocations.
3482 (Exploding the Stack Size with Alloca): Extend to try with
3484 (Exploding the Stack Size with Malloc): Likewise.
3486 * tests/calc.at (Simple LALR Calculator): Don't specify
3487 %skeleton "push.c" since %push-pull-parser implies that now.
3488 * tests/headers.at (export YYLTYPE): Don't check for the push
3489 declarations. Otherwise, this test case can't be used to see if push
3490 mode can truly emulate pull mode.
3491 * tests/input.at (Torturing the Scanner): Likewise.
3492 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
3493 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
3494 AT_YACC_IF, which now includes the case of push mode since %skeleton
3495 need not be used for push mode. This will be more intuitive once
3496 push.c is renamed to yacc.c.
3498 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3500 For push mode, convert yyparse from a macro to a function, invoke yylex
3501 instead of passing a yylexp argument to yypull_parse, and don't
3502 generate yypull_parse or yyparse unless %push-pull-parser is declared.
3503 Discussed starting at
3504 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
3505 * data/bison.m4 (b4_pull_if): New.
3506 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
3507 * data/push.c: Improve M4 quoting a little.
3508 (b4_generate_macro_args, b4_parenthesize): Remove.
3509 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
3510 any time a pull parser is requested.
3511 Don't #define this as a wrapper around yypull_parse. Instead, when
3512 both push and pull are requested, make it a function that does that
3514 (yypull_parse): If there's a b4_prefix, #define this to
3515 b4_prefix[pull_parse] when both push and pull are requested.
3516 Don't define this as a function unless both push and pull are
3518 Remove the yylexp argument and hard-code yylex invocation instead.
3519 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
3521 * src/getargs.c (pull_parser): New global initialized to true.
3522 * getargs.h (pull_parser): extern it.
3523 * src/output.c (prepare): Insert pull_flag muscle.
3524 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
3525 (prologue_declaration): Set both push_parser and pull_parser = true for
3526 %push-pull-parser. Set push_parser = true and pull_parser = false for
3528 * src/scan-gram.l: Don't accept %push_parser as an alternative to
3529 %push-parser since there's no backward-compatibility concern here.
3530 Scan %push-pull-parser.
3531 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
3532 instead of %push-parser.
3533 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
3534 prototype it in the module that calls yyparse.
3535 * tests/input.at (Torturing the Scanner): Likewise.
3536 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
3538 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
3540 Update etc/bench.pl. Optimize push mode a little (the yyn change
3541 deserves most of the credit).
3542 * Makefile.am (SUBDIRS): Add etc subdirectory.
3543 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
3544 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
3545 yytoken, yyval, and yyloc declarations to...
3546 (yyparse or yypush_parse): ... here to improve performance. For
3547 yypush_parse invocations after the first, be sure to assign yyn its old
3549 (yypstate_new): Don't bother initializing the yyresult field since the
3550 initial value isn't used.
3551 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
3552 remove the #define that, in push mode, set it to yyps->NAME.
3553 * etc/Makefile.am: New.
3554 * etc/bench.pl: Remove and build it instead from...
3555 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
3556 "tests/bison" from the build directory by default rather than just
3557 invoking "bison" from $PATH.
3558 (calc_grammar): Update push parser code: don't declare yylval globally,
3559 don't define yyparse_wrapper, and don't #define yyparse.
3560 (bench_grammar): Update to check all working combinations of yacc.c,
3561 push.c, impure, pure, pull, and push.
3563 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3565 For push mode, add pull wrappers around yypush_parse.
3566 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
3567 (yypull_parse): New function wrapping yypush_parse.
3568 (yyparse): New #define wrapping yypull_parse.
3569 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
3571 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
3572 prototype yylex in the module that calls yyparse, and don't prototype
3573 yyparse there. Otherwise, the yyparse expansion won't compile.
3574 * tests/input.at (Torturing the Scanner): Likewise.
3576 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3578 Enable push parsers to operate in impure mode. Thus, %push-parser no
3579 longer implies %pure-parser. The point of this change is to move
3580 towards being able to test the push parser code by running the entire
3581 test suite as if %push-parser had been declared.
3582 * data/push.c (yypush_parse): For impure mode, remove the
3583 yypushed_char, yypushed_val, and yypushed_loc arguments.
3584 Instead, declare these as local variables initialized to the global
3585 yychar, yylval, and yylloc.
3586 For the first yypush_parse invocation only, restore the initial values
3587 of these global variables when it's time to read a token since they
3588 have been overwritten.
3589 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
3591 * tests/calc.at (Simple LALR(1) Calculator): Always declare
3592 %pure-parser along with %push-parser since this test case was designed
3593 for pure push parsers.
3594 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
3595 (AT_YACC_OR_PUSH_IF): New.
3596 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
3597 add a note that it's still wrong for some cases (as it has been for a
3599 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
3600 %push-parser no longer implies %pure-parser.
3602 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3604 Remove some unnecessary differences between the pull parser code and
3605 the push parser code. This patch enables yynerrs in push mode.
3606 * data/push.c: Reformat M4 a little.
3607 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
3608 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
3609 because push mode is on. Instead, if pure mode is on, move yynerrs
3611 (b4_declare_parser_state_variables): ... here.
3612 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
3613 to yyps->NAME so it can be used in yypush_parse.
3614 (yypush_parse): Don't omit uses of yynerrs in push mode.
3616 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3618 Fix bug such that the first pushed token's value and location are
3619 sometimes overwritten (sometimes by %initial-action) before being used.
3620 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
3621 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
3622 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
3623 more closely mimic the pull parser logic.
3624 Don't copy the pushed token to yychar, yylval, and yylloc until it's
3625 time to read a token, which is after any initialization of yylval and
3627 (gottoken): Rename label to...
3628 (yyread_pushed_token): ... for clarity and to avoid infringing on the
3631 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3633 Rearrange initialization of the parser state variables so that the
3634 skeleton doesn't have to have a copy for pull mode and another for push
3635 mode. This patch also fixes at least a bug such that yylloc was not
3636 initialized (with b4_location_initial_line and
3637 b4_location_initial_column) upon calling yypush_parse. However, that
3638 initialization now overwrites the first token's location;
3639 %initial-action assigning @$ already did the same thing, and both bugs
3640 will be fixed in a later patch.
3641 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
3642 (b4_declare_parser_state_variables): Remove initialization of yytoken,
3643 yyss, yyvs, yyls, and yystacksize.
3644 (yypstate_new): Remove initialization of some yypstate fields: yystate,
3645 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
3647 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
3648 yyps->NAME so it can be used in yypush_parse.
3649 (yyparse or yypush_parse): For yypush_parse, don't print the
3650 "Starting parse" diagnostic for invocations after the first.
3651 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
3652 yypush_parse, only do it for the first invocation.
3653 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
3654 initialization to occur in yypush_parse but only on the first
3657 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3659 * data/push.c: Add CPP guards around push parser declarations in both
3660 the header and the code file.
3661 In the code file, move the push parser declarations to the same place
3662 they appear in the header file.
3663 Clean up the M4 some, especially the inconsistent underquoting in
3664 some b4_c_function_def and b4_c_function_decl uses.
3666 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3668 Encapsulate the push parser state variables into an M4 macro so the
3669 push skeleton doesn't have to list them again for pull mode's yyparse.
3670 For push mode, remove yypush_parse's local equivalents of these
3671 variables to eliminate unnecessary copying between the two sets at
3672 run-time. This patch also fixes at least a bug related to multiple
3673 %initial-action invocations in push mode.
3674 * data/push.c (b4_declare_parser_variables): Rename to...
3675 (b4_declare_scanner_communication_variables): ... this for clarity and
3677 (b4_declare_yyparse_variables): Remove and move its contents to the one
3678 spot where it was invoked.
3679 (b4_declare_parser_state_variables): New macro containing the parser
3680 state variables required by push mode.
3681 (struct yypstate): Replace all fields but yynew with
3682 b4_declare_parser_state_variables.
3683 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
3684 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
3685 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
3686 (yyparse or yypush_parse): For yyparse in pull mode, replace local
3687 parser state variable declarations with
3688 b4_declare_parser_state_variables.
3689 Don't initialize parser state variables when calling yypush_parse since
3690 yypstate_new already does that.
3691 Invoke the user's initial action only upon the first yypush_parse
3693 Remove all code that copies between the local parser state variables
3696 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3698 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
3699 prevent a name collision in a future patch where these names will
3700 sometimes be #define'd.
3701 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
3702 since it no longer has the same name as the existing argument.
3703 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
3705 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
3706 and Joel E. Denny <jdenny@ces.clemson.edu>
3708 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
3709 that the argument is case-insensitive, and there's no `=' here.
3710 For the %skeleton entry, mention that %language is better.
3711 (Bison Options): Likewise for --language and --skeleton. Move the
3712 --skeleton entry so that the `Tuning the parser' section is sorted
3713 alphabetically on long options.
3714 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
3715 %language directive in detail here; cross-reference the %language
3716 documentation instead.
3717 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
3718 `%require "2.3b"' so that the example is always up-to-date.
3719 (Table of Symbols): Add entries for %language and %skeleton.
3720 * examples/extexi (normalize): Instead of replacing every %require
3721 argument with the current Bison version, just substitute for
3722 `@value{VERSION}'. This guarantees that we're testing what actually
3723 appears in the documentation.
3724 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
3725 rather than `@VERSION@'.
3727 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3729 * NEWS: Reword the %language news a bit, and put it earlier.
3731 * src/getargs.c (skeleton_arg): Last arg is now location const *.
3732 Rewrite to simplify the logic.
3733 (language_argmatch): Likewise.
3734 (program_name): We now own this var.
3735 * src/getargs.h (struct bison_language): Use char[] rather than
3738 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
3740 * src/complain.c (program_name): Remove decl; no longer needed.
3741 * src/main.c (program_name): Remove; now belongs to getargs.
3743 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
3745 * NEWS: Document %language.
3747 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
3749 * data/c-skel.m4, data/c++-skel.m4: New files.
3750 * data/glr.c: Complain on push parsers.
3752 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
3754 (Decl Summary): Document %language and %skeleton.
3755 (Command line): Document -L.
3757 * examples/extexi: Rewrite %require directive.
3758 * examples/calc++/Makefile.am: Pass VERSION to extexi.
3760 * src/files.c (compute_exts_from_gc): Look in language structure
3762 (compute_file_name_parts): Check whether .tab should be added.
3763 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
3764 (language, skeleton_arg, language_argmatch): New.
3765 (long_options): Add --language.
3766 (getargs): Use skeleton_arg, add -L/--language.
3767 * src/getargs.h: Include location.h.
3768 (struct bison_language, language, skeleton_arg, language_argmatch): New.
3769 * src/output.c (prepare): Pick default skeleton from struct language.
3770 Don't dispatch C skeletons here.
3771 * src/parse-gram.y (PERCENT_LANGUAGE): New.
3772 (prologue_declaration): Add "%language" rule, use skeleton_arg.
3773 * src/scan-gram.l ("%language"): New rule.
3775 * tests/calc.at: Test %skeleton and %language.
3776 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
3777 (AT_GLR_IF): Look for %skeleton "glr.cc".
3778 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
3779 (AT_YACC_IF): Reject %language.
3781 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3783 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
3784 since it wasn't used; only the typedef name 'semantic_type' is needed.
3785 Also, omit trailing white space.
3787 * bootstrap: Sync from coreutils.
3788 (gnulib_extra_files): Add build-aux/announce.gen.
3789 (slurp): Adjust .gitignore files like .cvsignore files.
3790 * build-aux/announce-gen: Remove from CVS, since bootstrap
3793 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
3795 Make %push-parser imply %pure-parser. This fixes several bugs; see
3796 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
3797 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
3799 * data/push.c: Don't bother testing b4_push_if when deciding whether
3800 to expand b4_declare_parser_variables globally.
3801 (yypush_parse): Likewise in here.
3803 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
3804 (yy_reduce_print): Reformat M4 for readability.
3806 2006-12-15 Bob Rossi <bob@brasko.net>
3807 and Joel Denny <jdenny@ces.clemson.edu>
3809 * data/push.c (yypstate): Add typedef, and update all uses of
3810 struct yypstate to just yypstate.
3811 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
3813 2006-12-14 Bob Rossi <bob@brasko.net>
3815 * data/push.c (yypush_parse): Declare prototype regardless of
3818 2006-12-14 Bob Rossi <bob@brasko.net>
3820 * data/push.c (yyparse): Remove the prototype and the #define when in
3823 2006-12-13 Bob Rossi <bob@brasko.net>
3825 * data/push.c (yypstate_init): Rename to...
3826 (yypstate_new): ... this and use b4_c_function_def.
3827 (yypstate_delete): New.
3828 (yypush_parse): Change parameters yynval and yynlloc to be const.
3829 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
3830 yypstate_delete functions.
3832 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
3834 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
3835 strange test case titles. Reported by Bob Rossi.
3837 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
3839 * TODO: Add pointer to Sylvain Schmitz's work on static detection
3840 of potential ambiguities in GLR grammers.
3842 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
3844 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
3845 `bison ', use m4_index instead of m4_substr since chopping up a string
3846 containing M4-special characters causes problems here.
3848 Fix a couple of bugs related to special characters in user-specified
3849 file names, and make it easier for skeletons to compute output file
3850 names with the same file name prefix as Bison-computed output file
3852 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
3853 b4_parser_file_name and b4_spec_defines_file instead of
3854 @output_parser_name@ and @output_header_name@, which are now redundant.
3855 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
3856 b4_parser_file_name, b4_spec_defines_file, and the new
3857 @basename(FILENAME@) instead of @output_parser_name@ and
3858 @output_header_name@, which inappropriately escaped the file names as
3860 * src/files.c (all_but_ext): Remove static qualifier.
3861 (compute_output_file_names): Move `free (all_but_ext)' to...
3862 (output_file_names_free): ... here since all_but_ext is needed later.
3863 * src/files.h (all_but_ext): Extern.
3864 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
3865 exactly what MUSCLE_INSERT_STRING used to do.
3866 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
3867 characters are escaped properly.
3868 * src/output.c (prepare): Define muscle file_name_all_but_ext as
3870 For pkgdatadir muscle, maintain previous functionality by using
3871 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
3872 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
3873 digraphs would never be expanded. Hopefully no one has M4-special
3874 characters in his Bison installation path.
3875 * src/scan-skel.l: Don't parse @output_header_name@ and
3876 @output_parser_name@ anymore since they're now redundant.
3877 In @output, use decode_at_digraphs.
3878 Parse a new @basename command that invokes last_component.
3879 (decode_at_digraphs): New.
3880 (BASE_QPUTS): Remove unused.
3881 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
3882 (Output file name): New tests.
3884 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
3886 Warn about output files that are generated by the skeletons and that
3887 conflict with other output files.
3888 * data/glr.c: Don't generate the header file here when glr.cc does.
3889 * src/files.c (file_names, file_names_count): New static globals.
3890 (compute_output_file_names): Invoke output_file_name_check for files
3891 not generated by the skeletons and remove existing checks.
3892 (output_file_name_check): New function that warns about conflicting
3894 (output_file_names_free): Free file_names.
3895 * src/files.h (output_file_name_check): Declare.
3896 * src/scan-skel.l: Invoke output_file_name_check for files generated by
3898 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
3899 (Conflicting output files): New tests.
3901 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3903 * doc/bison.texinfo: Fix a couple of typos.
3905 2006-12-08 Bob Rossi <bob@brasko.net>
3907 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
3909 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
3911 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
3912 (yypush_parse): Rename yypvars argument to yyps and remove redundant
3914 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
3915 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
3917 2006-12-07 Bob Rossi <bob@brasko.net>
3918 and Joel Denny <jdenny@ces.clemson.edu>
3920 * data/push.c (yypvarsinit): Change return type from void* to struct
3921 yypvars*. No longer cast to void* on return.
3922 (struct yypvars): Remove yylen since it need not be remembered between
3923 yypushparse invocations.
3924 (yypushparse): Don't copy between yylen and pv->yylen.
3926 2006-12-05 Bob Rossi <bob@brasko.net>
3928 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
3929 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
3930 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
3931 (struct yypvars): Remove b4_declare_parser_variables.
3932 (yypvarsinit): Remove init code for removed variables.
3933 (global scope): Do not declare b4_declare_parser_variables if
3935 (yypushparse): Add b4_declare_parser_variables.
3936 Init new local variables, and remove init code for removed
3939 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
3940 and yyparse for other modes.
3941 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
3942 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
3943 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
3944 (AT_PURE_LEX_IF): True if pure or push parser.
3946 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
3948 Document Yacc prologue alternatives and default %destructor's and
3949 %printer's as experimental. Don't mention Java yet. Discussed at
3950 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.

3970 all but one occurrence of %name-prefix.
3971 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
3972 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
3973 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
3974 occurrence of each of %file-prefix and %output. Add check for %defines
3976 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
3977 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
3978 Remove the `=' from %output.
3980 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
3982 Don't escape $ in test case titles since Autoconf 2.61 now does that

3989 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
3991 Rename <!> to <>. Discussed starting at

4001 * tests/actions.at (Default tagless %printer and %destructor,
4002 Default tagged and per-type %printer and %destructor,
4003 Default %printer and %destructor are not for error or $undefined,
4004 Default %printer and %destructor are not for $accept,
4005 Default %printer and %destructor for mid-rule values): Update.
4006 * tests/input.at (Default %printer and %destructor redeclared,
4007 Unused values with default %destructor): Update.
4009 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>

4017 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
4019 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
4020 it was double-quoted.
4021 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
4022 grammar is maintained with Bison's highest standards.
4023 * src/getargs.c: Fix some typos in Doxygen comments.
4025 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
4027 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
4028 later. Reported by Paul Eggert in
4029 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
4030 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
4031 * src/scan-code.l (translate_action): Don't bother invoking
4032 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
4033 (code_scanner_free): Instead of invoking
4034 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

4042 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
4043 has been called previously for the same key.
4044 (muscle_find): Return storage instead of value so that
4045 --enable-gcc-warnings doesn't produce warnings that the return discards
4046 const. aver that the value and storage are the same since storage
4047 could potentially be NULL when value is not.
4048 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
4051 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4053 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
4054 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
4055 us a slightly cleaner distribution, and also works.
4056 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
4059 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
4060 and Paul Eggert <eggert@cs.ucla.edu>

4063 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
4064 (spec_defines_file, dir_prefix): Now char *, not const char *,
4065 since they are freed.
4066 * src/files.c: Likewise.
4067 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
4069 (tr): Now operates in-place. All uses changed.
4070 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
4072 (compute_file_name_parts, compute_output_file_names): Don't store
4073 read-only data in variables that will be freed.
4074 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
4075 src_extension, and header_extension.
4076 (output_file_names_free): New public function to free
4077 spec_verbose_file, spec_graph_file, spec_defines_file,
4078 parser_file_name, and dir_prefix.
4079 * src/getargs.c (getargs): Don't store read-only data in variables that
4081 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
4082 (which previously existed but was unused), and quotearg_free.
4083 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
4084 * src/muscle_tab.c: Likewise.
4085 (muscle_entry): Make the value char const *,
4086 and add a new storage member that is char * and can be freed.
4087 (muscle_entry_free): New private function.
4088 (muscle_init): Use it instead of free.
4089 (muscle_insert, muscle_grow): Update and use new storage member.
4090 (muscle_code_grow): Free the string passed to muscle_grow
4091 since it's not needed anymore.
4092 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
4093 add a new `char *code' member.
4094 ("{...}"): Declare semantic type as code.
4095 * src/scan-code.h (translate_rule_action):
4096 (translate_symbol_action, translate_code, translate_action): Return
4097 `char const *' rather than `char *' since external code should not free
4099 * src/scan-code.l: Likewise.
4100 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
4101 which is "{...}" in the parser.
4102 * tests/Makefile.am (maintainer-check-valgrind): Set
4103 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
4105 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
4107 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
4108 expecting a non-zero exit status sets --leak-check=summary and
4109 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
4110 this case, and we don't want to hear about it.
4112 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4114 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
4115 instead of from the template, to simplify configuration a bit.

4128 the value is a set/used mid-rule value unless
4129 --warnings=midrule-values was specified.
4130 * tests/input.at (Unused values, Unused values before symbol
4131 declarations): Run tests with and without --warnings=midrule-values.
4133 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
4134 than LIST_FREE directly.
4136 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
4138 Finish implementing --warnings=error, which should not be implied by
4139 --warnings=all (or by its synonyms -W and --warnings without
4141 * src/complain.c (set_warning_issued): New function to report that
4142 warnings are being treated as errors and to record an error if so.
4144 (warn_at, warn): ... here.
4145 * src/getargs.c (warnings_args, warnings_types): Reorder so that
4146 "error - warnings are errors" does not appear above "all - all of the
4148 (getargs): For -W and --warnings without subarguments, don't let
4149 FLAGS_ARGMATCH set warnings_error in warnings_flag.

4152 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
4154 * src/getargs.c (flags_argmatch): Don't cause segmentation fault for
4155 empty subargument list. For example: `bison --warnings= parser.y'.
4157 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
4159 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
4160 the parser header file so that gcc doesn't warn.

4164 Split the default %destructor/%printer into two kinds: <*> and <!>.
4165 Discussed starting at
4166 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00060.html>.
4167 * NEWS (2.3a+): Mention.
4168 * doc/bison.texinfo (Freeing Discarded Symbols): Document this and the

4181 SYMLIST_DEFAULT case into SYMLIST_DEFAULT_TAGGED and
4182 SYMLIST_DEFAULT_TAGLESS.
4183 * src/symlist.h: Update symbol_list_default*_new prototypes.
4184 (symbol_list.content_type): Split enum value SYMLIST_DEFAULT into
4185 SYMLIST_DEFAULT_TAGGED and SYMLIST_DEFAULT_TAGLESS.
4186 * src/symtab.c (default_destructor, default_destructor_location,
4187 default_printer, default_printer_location): Split each into tagged and
4189 (symbol_destructor_get, symbol_destructor_location_get,
4190 symbol_printer_get, symbol_printer_location_get): Implement tagged
4191 default and tagless default cases.
4192 (default_destructor_set, default_printer_set): Split each into tagged
4193 and tagless versions.
4194 * src/symtab.h: Update prototypes.

4210 Don't apply the default %destructor/%printer to an unreferenced midrule
4212 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
4213 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
4214 like $@n instead of just @n so that the default %destructor/%printer
4215 logic doesn't see them as user-defined symbols.
4216 (symbol_is_dummy): Check for both forms of the name.
4217 * src/reader.c (packgram): Remove the `$' from each midrule symbol
4218 name for which the midrule value is referenced in any action.
4219 * tests/actions.at (Default %printer and %destructor for mid-rule
4221 * tests/regression.at (Rule Line Numbers, Web2c Report): Update output
4222 for change to dummy symbol names.

4226 Warn about unset midrule $$ if the corresponding $n is used.
4227 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
4229 (packgram): Before invoking grammar_rule_check on any rule, make sure
4230 all actions have already been scanned in order to set `used' flags.
4231 Otherwise, checking that a midrule's $$ is set will not always work
4232 properly because the midrule check must forward-reference the midrule's
4234 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
4237 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
4239 More improvements to the documentation of the prologue alternatives:
4240 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
4242 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
4243 some text to clarify the relative importance of the new directives and
4244 to show how these directives may be viewed as code labels.
4246 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
4248 Similar to the recently removed %before-header, add %code-top as the
4249 alternative to the pre-prologue. Mentioned at
4250 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.

4314 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
4316 Fix testsuite for ./configure --enable-gcc-warnings:
4317 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.

4361 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
4362 variable was sometimes used without being initialized. This

4365 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4367 * bootstrap (usage, main program, symlink_to_gnulib): Add option
4368 --copy. Inspired by a suggestion from Bruno Haible.
4370 2006-10-03 Jim Meyering <jim@meyering.net>

4373 sticks with the automake default in generating dependencies.
4375 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4377 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

4453 and try to make such failures easier to catch in the future.
4454 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
4455 that's now the caller's responsibility.
4456 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
4457 Set yychar = YYEOF if it's negative.
4458 * tests/actions.at (yylex): Abort if asked to read past EOF.

4468 Fix problems with translating English-language diagnostics.
4469 * bootstrap: Fix bug introduced in recent bootstrap changes, with

4478 Merge bootstrap changes from coreutils.
4480 2006-09-28 Jim Meyering <jim@meyering.net>
4482 Automatically generated dependencies are important even
4483 when all of the sources in a directory come from gnulib.
4484 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake

4523 to copies-of-gnulib.
4524 (cp_mark_as_generated, slurp, gnulib_files):
4525 Avoid making a copy if it's the same as the old version.
4526 (gnulib_files): Add support for this variable (used by Bison).
4528 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
4530 * src/getargs.c (usage): Rework to use conventions similar to
4531 coreutils, to make translation a bit easier and the code a bit
4532 smaller. Problem reported by Tim Van Holder.
4534 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
4536 Use some of gnulib's new modules, taken from coreutils.

4546 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
4548 (GNULIB_AUTOCONF_SNIPPET): Remove.
4549 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
4551 * lib/.cvsignore: Add inttypes_.h.
4552 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
4553 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
4554 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
4555 no-longer-necessary initializations.
4556 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.

4559 * src/system.h: Likewise.
4560 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,

4562 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
4563 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
4564 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
4565 * src/system.h: Include inttypes.h unconditionally, now that we
4566 use the inttypes module. Don't bother to include stdint.h, since
4567 inttypes.h now does that for us.

4570 * src/main.c: Likewise.
4571 * src/output.c: Likewise.
4572 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,

4576 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
4577 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
4579 * src/parse-gram.y (symbol_declaration): Don't put statements
4580 before declarations; it's not portable to C89.
4581 * src/scan-code.l (handle_action_at): Likewise.
4583 * src/scan-code.l: Always initialize braces_level; the old code
4584 left it uninitialized and therefore had undefined behavior.
4586 Don't attempt to redefine 'assert', since it runs afoul of
4587 systems where standard headers (mistakenly) include <assert.h>.
4588 Instead, define and use our own alternative, called 'aver'.
4589 * src/reader.c: Don't include assert.h, since we no longer
4591 * src/scan-code.l: Likewise.
4592 * src/system.h (assert): Remove, replacing with....
4593 (aver): New function, taking a bool arg. All uses changed.

4620 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
4621 "#define YYSTYPE int" that caused "make maintainer-check" to fail
4622 due to header ordering dependencies. I don't know why the #define
4625 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
4626 runtime cost when YYDEBUG is not defined, and so that some tests
4627 that used to fail now work. Problem and initial suggestion by
4629 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
4630 * data/glr.cc (b4_parser_class_name):
4631 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
4632 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
4633 (yydebug_) [YYDEBUG]: New member.
4634 (yycdebug_): Now defined only if YYDEBUG.
4635 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
4636 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
4637 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
4639 (debug_stream, set_debug_stream, debug_level, set_debug_level):
4640 Define only if YYDEBUG.
4641 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
4643 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
4644 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
4645 AT_CHECK_CALC_GLR_CC that are working now.
4647 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
4649 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
4650 We don't need them in glr.cc, and glr.c defines them.
4651 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
4652 assumes that defining it to anything is the same as defining
4653 it to 1. Problem reported by Paolo Bonzini.
4655 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
4657 * data/c.m4 (b4_null, b4_case): Define.
4658 * src/output.c (prepare_symbols): Use b4_null.
4659 (user_actions_output): Use b4_case.
4661 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
4663 * data/glr.c (b4_shared_declarations): Put start-header first,
4664 before any #includes that we generate, so that feature-test
4665 macros work. Problem reported by Michael Deutschmann in
4666 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
4667 * data/lalr1.cc: Likewise.
4668 * doc/bison.texinfo (Prologue): Document that feature-test macros
4669 should be defined before any Bison declarations.
4670 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
4671 that depend on location.hh after, not before, Bison decls, since
4672 we now include location.hh after the first user prologue.
4674 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
4675 Sander Brandenburg in
4676 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
4677 Also, fix minor white space and comment issues.
4678 (Prologue): Mention that it's better to define feature-test macros
4679 before Bison declarations. Problem reported by Michael Deutschmann.
4681 * README-cvs: Fix typo: "&" should be "&&". Problem reported
4683 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
4684 This adjusts to recent gnulib changes.
4686 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4688 Finish implementation of per-type %destructor/%printer. Discussed
4690 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
4692 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
4693 * NEWS (2.3+): Add a description of this feature to the default
4694 %destructor/%printer description.
4695 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
4696 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4697 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
4698 list node contains a semantic type.
4699 * src/symtab.c, src/symtab.h: Extend with a table that associates
4700 semantic types with their %destructor's and %printer's.
4701 (semantic_type_from_uniqstr, semantic_type_get,
4702 semantic_type_destructor_set, semantic_type_printer_set): New functions
4703 composing the public interface of that table.
4704 (symbol_destructor_get, symbol_destructor_location_get,
4705 symbol_printer_get, symbol_printer_location_get): If there's no
4706 per-symbol %destructor/%printer, look up the per-type before trying
4708 * tests/actions.at (Per-type %printer and %destructor): New test case.
4709 * tests/input.at (Default %printer and %destructor redeclared):
4710 Extend to check that multiple occurrences of %symbol-default in a
4711 single %destructor/%printer declaration is an error.
4712 (Per-type %printer and %destructor redeclared, Unused values with
4713 per-type %destructor): New test cases.
4715 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4717 Require default %destructor/%printer to be declared using
4718 %symbol-default instead of an empty symbol list, and start working on
4719 new per-type %destructor/%printer. Discussed at
4720 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
4721 * NEWS (2.3+): Add %symbol-default to example.
4722 * bison.texinfo (Freeing Discarded Symbols): Likewise.
4723 (Table of Symbols): Add entry for %symbol-default.
4724 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
4725 (generic_symlist, generic_symlist_item): New nonterminals for creating
4726 a list in which each item is a symbol, semantic type, or
4728 (grammar_declaration): Use generic_symlist in %destructor and %printer
4729 declarations instead of symbols.1 or an empty list.
4730 (symbol_declaration, precedence_declaration, symbols.1): Update actions
4731 for changes to symbol_list.
4732 * src/reader.c: Update for changes to symbol_list.
4733 * src/scan-code.l: Likewise.
4734 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
4735 * src/symlist.c, src/symlist.h: Extend such that a list node may
4736 represent a semantic type or a %symbol-default in addition to just an
4737 ordinary symbol. Add switched functions for setting %destructor's and
4739 * tests/actions.at, tests/input.at: Add %symbol-default to all default
4740 %destructor/%printer declarations.
4742 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
4744 Whether the default %destructor/%printer applies to a particular symbol
4745 isn't a question of whether the user *declares* that symbol (in %token,
4746 for example). It's a question of whether the user by any means
4747 *defines* the symbol at all (by simply using a char token, for
4748 example). $end is defined by Bison whereas any other token with token
4749 number 0 is defined by the user. The error token is always defined by
4750 Bison regardless of whether the user declares it with %token, but we
4751 may one day let the user define error as a nonterminal instead.
4752 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
4753 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
4754 the meaning of "user-defined".
4755 * tests/actions.at (Default %printer and %destructor for user-declared
4756 end token): Rename to...
4757 (Default %printer and %destructor for user-defined end token): ...
4760 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
4761 computation of whether to apply the default, don't maintain a list of
4762 every Bison-defined symbol. Instead, just check for a first character
4763 of '$', which a user symbol cannot have, and check for the error token.
4765 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
4767 Don't apply the default %destructor or %printer to the error token,
4768 $undefined, or $accept. This change fits the general rule that the
4769 default %destructor and %printer are only for user-declared symbols,
4770 and it solves several difficulties that are described in the new test
4772 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
4773 * tests/actions.at (Default %printer and %destructor are not for error
4774 or $undefined, Default %printer and %destructor are not for $accept):
4777 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
4779 Allow %start after the first rule.
4780 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
4781 when parsing the first rule.
4782 (check_and_convert_grammar): Search for it here after all grammar
4783 declarations have been parsed. Skip midrules, which have dummy LHS
4785 * src/symtab.c (symbol_is_dummy): New function.
4786 * src/symtab.h (symbol_is_dummy): Declare it.
4787 * tests/input.at (%start after first rule): New test.
4789 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4791 Redo some of the previous commit: add back the ability to use
4792 non-aliased/undeclared string literals since it might be useful to
4793 those declaring %token-table.
4794 * src/reader.c (check_and_convert_grammar): Undo changes in previous
4795 commit: don't worry about complaints from symbols_pack.
4796 * src/symtab.c (symbol_new, symbol_class_set,
4797 symbol_check_alias_consistency): Undo changes in previous commit: count
4798 each string literal as a new symbol and token, assign it a symbol
4799 number, and don't complain about non-aliased string literals.
4800 (symbols_pack): Since symbol_make_alias still does not decrement symbol
4801 and token counts but does still set aliased tokens to the same number,
4802 symbol_pack_processor now leaves empty slots in the symbols array.
4804 * tests/regression.at (Undeclared string literal): Remove test case
4805 added in previous commit since non-aliased string literals are allowed
4807 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
4808 remove unnecessary string literal declarations.
4809 * tests/sets.at (Firsts): Likewise.
4811 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4813 Don't allow an undeclared string literal, but allow a string literal to
4814 be used before its declaration.
4815 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
4816 symbols_pack complained.
4817 * src/symtab.c (symbol_new): Don't count a string literal as a new
4819 (symbol_class_set): Don't count a string literal as a new token, and
4820 don't assign it a symbol number since symbol_make_alias does that.
4821 (symbol_make_alias): It's not necessary to decrement the symbol and
4822 token counts anymore. Don't assume that an alias declaration occurs
4823 before any uses of the identifier or string, and thus don't assert that
4824 one of them has the highest symbol number so far.
4825 (symbol_check_alias_consistency): Complain if there's a string literal
4826 that wasn't declared as an alias.
4827 (symbols_pack): Bail if symbol_check_alias_consistency failed since
4828 symbol_pack asserts that every token has been assigned a symbol number
4829 although undeclared string literals have not.
4830 * tests/regression.at (String alias declared after use, Undeclared
4831 string literal): New test cases.
4832 (Characters Escapes, Web2c Actions): Declare string literals as
4834 * tests/sets.at (Firsts): Likewise.
4836 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
4838 In the grammar scanner, STRING_FINISH unclosed constructs and return
4839 them to the parser in order to improve error messages.
4840 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
4841 SC_BRACED_CODE, SC_PROLOGUE): Implement.
4842 * tests/input.at (Unclosed constructs): New test case.
4843 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
4846 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
4849 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
4851 Handle string aliases for character tokens correctly.
4852 * src/symtab.c (symbol_user_token_number_set): If the token has an
4853 alias, check and set its alias's user token number instead of its own,
4854 which is set to indicate the alias. Previously, every occurrence of
4855 the character token in the grammar overwrote that alias indicator with
4857 * tests/input.at (String aliases for character tokens): New test.
4859 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
4861 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
4863 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
4865 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
4866 to prevent failures when building on older platforms.
4867 Check for autopoint failure.
4868 Set XGETTEXT_OPTIONS to values that check for C format strings,
4869 so that translators are warned about them (this also helps
4870 prevent core dumps).
4872 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
4873 function, since it simplifies our code a bit.
4875 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
4876 rather than -W, so we don't get bogus warnings about sign comparisons.
4877 Add -Wpointer-arith, since that warning is useful (it reports code
4878 that does not conform to C89 and that some compilers reject).
4879 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
4880 since it's no longer needed.
4882 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
4884 Clean up scanners a bit.
4885 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
4886 definitions so gcc won't warn when obstack_for_string is unused.
4887 * src/scan-code.l: config.h and system.h are already #include'd by
4888 scan-code-c.c, so get rid of them here.
4889 * src/scan-gram.l: Likewise.
4890 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
4891 definitions rather than duplicating the rest of it.
4892 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
4894 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
4896 Suppress signed/unsigned comparison warnings for yycheck.
4897 * data/c.m4 (b4_safest_int_type): New macro.
4898 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
4899 a signed int type, cast it to b4_safest_int_type first.
4900 * data/yacc.c: Likewise.
4901 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
4904 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
4906 * doc/bison.texinfo: Fix some typos.
4908 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
4910 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
4911 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
4913 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
4914 the latest gnulib does this a different way.
4915 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
4916 translation was patched, so stop omitting it.
4918 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
4920 Enable declaration of default %printer/%destructor. Make the parser
4921 use these for all user-declared grammar symbols for which the user does
4922 not declare a specific %printer/%destructor. Thus, the parser uses it
4923 for token 0 if the user declares it but not if Bison generates it as
4924 $end. Discussed starting at
4925 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
4926 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
4928 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
4929 * NEWS (2.3+): Mention.
4930 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
4931 declare a %destructor for a mid-rule's semantic value. It's just
4932 impossible to declare one specific to it.
4933 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
4934 code. Describe default %destructor form.
4935 * src/parse-gram.y (grammar_declaration): Parse default
4936 %printer/%destructor declarations.
4937 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
4938 and symbol_destructor_location_get rather than accessing the destructor
4939 and destructor_location members of struct symbol.
4940 (symbol_printers_output): Likewise but for %printer's.
4941 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
4943 * src/symtab.c (default_destructor, default_destructor_location,
4944 default_printer, default_printer_location): New static global
4945 variables to record the default %destructor and %printer.
4946 (symbol_destructor_get, symbol_destructor_location_get,
4947 symbol_printer_get, symbol_printer_location_get): New functions to
4948 compute the appropriate %destructor and %printer for a symbol.
4949 (default_destructor_set, default_printer_set): New functions to set the
4950 default %destructor and %printer.
4951 * src/symtab.h: Prototype all those new functions.
4952 * tests/actions.at (Default %printer and %destructor): New test to
4953 check that the right %printer and %destructor are called, that they're
4954 not called for $end, and that $$ and @$ work correctly.
4955 (Default %printer and %destructor for user-declared end token): New
4956 test to check that the default %printer and %destructor are called for
4957 a user-declared end token.
4958 * tests/input.at (Default %printer and %destructor redeclared, Unused
4959 values with default %destructor): New tests to check related grammar
4960 warnings and errors.
4962 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
4964 Clean up handling of %destructor for the end token (token 0).
4965 Discussed starting at
4966 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
4968 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
4970 Make the skeletons consistent in how they pop the end token and invoke
4972 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
4973 state, which has token number 0, since this would invoke the
4974 %destructor for the end token.
4975 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
4976 until after shifting the end token, or else it won't be popped.
4977 * data/yacc.c (yyparse): Likewise.
4979 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
4980 it's the end token. Upon termination, destroy an unshifted lookahead
4981 even when it's the end token.
4982 * data/lalr1.cc (yy::parser::parse): Likewise.
4983 * data/yacc.c (yyparse): Likewise.
4985 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
4986 value warnings for the end token when the user gives the end token a
4989 * tests/actions.at (Printers and Destructors): Test all the above.
4991 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
4993 Update to latest gnulib and gettext versions.
4994 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
4996 (gnulib_files): Add m4/warning.m4. Don't worry about files
4997 overwritten by autopoint.
4998 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
4999 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
5001 Don't use autoreconf; instead, invoke autopoint etc. by hand,
5002 so that we can remove the intl files at a better time.
5003 (intl_files_to_remove): Remove aclocal.m4, since it gets
5004 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
5005 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
5006 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
5007 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
5008 Remove datarootdir hack; no longer needed.
5009 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
5010 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
5011 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
5013 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
5014 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
5016 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5018 * bootstrap: Adjust to today's change to gnulib-tool by invoking
5019 it with --assume-autoconf='latest-stable'.
5021 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
5023 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
5024 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
5026 * src/muscle_tab.h (muscle_grow): Replace the header comments with
5027 those from muscle_tab.c since the old ones are misleading.
5029 2006-07-13 Akim Demaille <akim@epita.fr>
5031 Support %define "KEY" {VALUE}.
5032 * src/scan-code.h, src/scan-code.l (translate_action)
5033 (translate_rule_action, translate_symbol_action, translate_code):
5034 Return char *, not const char *.
5035 * src/parse-gram.y (declaration): Rename as...
5036 (prologue_declaration): this.
5037 (string_content): Remove this nonterminal, use STRING.
5038 (braceless, content, content.opt): New nonterminal.
5040 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
5042 * src/scan-gram.l (getargs.h): Don't include it.
5044 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
5046 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
5047 rather than a for-loop that declares a local bool variable. This
5048 should work around a compatibility problem with a Cray x1e C++
5049 compiler reported by Hung Nguyen in
5050 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
5051 The for-loop was introduced in the 2004-11-17 change but I don't
5052 know why it was needed.
5054 2006-07-12 Akim Demaille <akim@epita.fr>
5056 * data/c.m4: Comment changes.
5058 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
5060 * src/complain.c (error_message, ERROR_MESSAGE): New.
5062 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
5063 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
5065 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5067 * NEWS: Instead of %union, you can define and use your own union type
5068 YYSTYPE if your grammar contains at least one <type> tag.
5069 Your YYSTYPE need not be a macro; it can be a typedef.
5070 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
5071 (Union Decl, Decl Summary): Document this.
5072 * data/glr.c (YYSTYPE): Implement this.
5073 * data/glr.cc (YYSTYPE): Likewise.
5074 * data/lalr1.cc (YYSTYPE): Likewise.
5075 * data/yacc.c (YYSTYPE): Likewise.
5076 * src/output.c (prepare): Output tag_seen_flag.
5077 * src/parse-gram.y (declaration, grammar_declaration):
5078 Use 'union_seen' rather than 'typed' to determine whether
5079 %union has been seen, since grammars can now be typed without
5081 (symbol_declaration, type.opt, symbol_def):
5082 Keep track of whether a tag has been seen.
5083 * src/reader.c (union_seen, tag_seen): New vars.
5085 * src/reader.h (union_seen, tag_seen, typed): Likewise.
5086 * src/scan-code.l (untyped_var_seen): New variable.
5087 (handle_action_dollar): Adjust to above changes.
5088 (handle_action_dollar, handle_action_at):
5089 Improve overflow checking for outlandish numbers.
5090 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
5091 avoid new diagnostics generated by above changes.
5092 * tests/regression.at (YYSTYPE typedef): Add test to check
5093 for type tags without %union.
5095 * src/symlist.c (symbol_list_length): Return int, not unsigned
5096 int, since callers expect int. This may need to get revisited
5097 once we have proper integer overflow checking.
5099 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
5100 object is now static.
5102 * src/getargs.c (flags_argmatch): Return void, not int,
5103 to pacify ./configure --enable-gcc-warnings.
5105 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
5106 since last_string is already defined to FLEX_PREFIX (last_string).
5108 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5110 Implement --warnings/-W.
5111 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
5113 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
5115 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
5116 (warnings_args, warnings_types): New.
5117 (getargs, short_options, long_options): Accept -W/--warnings.
5118 Sort the options by alphabetical order, upper case letter right
5119 before its lower case.
5121 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
5123 Change %merge result type clash warnings to errors. Discussed at
5124 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
5125 * src/reader.c (record_merge_function_type): Use complain_at.
5126 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5127 declared later): Update test case results.
5129 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5131 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
5132 to be in alphabetical order.
5133 (trace_args): Spelling fixes.
5135 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5137 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
5138 so they don't collide with user-defined macros.
5139 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
5140 this was never guaranteed, and now that we're using gnulib stdint,
5141 which defines int_fast16_t to long int, the problem is exposed.
5143 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
5145 * data/c.m4 (b4_basename): Simplify a bit, since we don't
5146 need the full POSIX semantics (and weren't implementing them
5149 Adjust to Autoconf 2.60 and today's gnulib.
5150 * bootstrap (gnulib_modules): Add stdint.
5151 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
5152 no longer copies it.
5153 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
5154 since stdint needs the former and wcwidth (which is now required
5155 by mbswidth) needs the latter.
5156 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
5157 work around a compatibility glitch between gettext 0.14.6 and
5159 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
5160 Do not check for uintptr_t, since new stdint module does the right
5162 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
5163 Add stdint.h, stdint_.h, wcwidth.h.
5164 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
5165 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
5166 stdint.m4, wchar_t.m4, wcwidth.m4.
5167 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
5168 usual order for ../lib/*.h files.
5169 (file_name_split): Use last_component, not base_name, to adjust
5171 * src/parse-gram.h: Include <strverscmp.h> in the usual order
5172 for ../lib/*.h files.
5173 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
5174 Define unconditionally, since we now assume the stdint module.
5175 * src/scan-skel.l: Include <dirname.h>.
5176 (BASE_QPUTS): Use last_component, not base_name.
5177 * src/system.h: Include <unlocked-io.h> in the usual order
5178 for ../lib/*.h files. Include <stdint.h> unconditionally,
5179 since we now use the stdint module.
5180 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
5181 HAVE_UINTPTR_T, since we now use the stdint module.
5182 (base_name): Remove decl, since files now include <dirname.h>
5185 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5187 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
5189 * data/yacc.c, data/glr.c, data/location.cc: Use them.
5190 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
5192 * tests/calc.at: Adjust.
5194 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5196 * data/c.m4 (b4_basename): New.
5197 (b4_syncline): Also output the location of its invocation (from
5199 (b4_user_action, b4_define_user_action, b4_user_actions)
5200 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
5201 (b4_user_stype): New.
5202 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
5204 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5206 In the grammar file, the first column is 1 not 0 on the first line as
5207 on every other line.
5208 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
5209 * tests/input.at (Torturing the Scanner): Update output.
5211 * src/scan-gram.l (scanner_cursor): Declare it static.
5213 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5215 In warnings, say "previous declaration" rather than "first
5217 * src/symtab.c (redeclaration): Do that here.
5218 * src/reader.c (record_merge_function_type): In the case of a result
5219 type clash, report the previous declaration rather than the very first
5220 one in the grammar file.
5221 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5222 declared later): Add a third declaration to check this behavior.
5223 * tests/input.at (Incompatible Aliases): Update output.
5225 2006-06-27 Akim Demaille <akim@epita.fr>
5227 * doc/Doxyfile.in: New.
5228 * doc/Makefile.am: Use it.
5229 * src/lalr.h, src/symtab.h: Initial doxygenation.
5231 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5233 Don't miss %merge result type warnings just because the LHS types are
5234 declared after the %merge. This continues the effort of the previous
5236 * src/reader.c (get_merge_function): Don't set the merger type yet.
5237 (record_merge_function_type): New function for setting the merger type
5238 and checking for clashes.
5239 (grammar_current_rule_merge_set): Set the location of the %merge for
5241 (packgram): Invoke record_merge_function_type for each rule now that
5242 all symbol type declarations have been parsed.
5243 * src/reader.h (merger_list.type_declaration_location): New member
5244 storing the location of the first %merge from which the type for this
5245 merging function was derived.
5246 * src/symlist.h (symbol_list.merger_declaration_location): New member
5247 storing the location of a rule's %merge, if any.
5248 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5249 declared later): New test to catch the error fixed by the above patch.
5251 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5253 Get action warnings (grammar_rule_check) right even when symbol
5254 declarations appear after the rules. Discussed at
5255 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
5257 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
5258 Don't mistake the type of $$ in a midrule to be that of its parent
5260 * src/reader.c (grammar_current_rule_end): Don't invoke
5261 grammar_rule_check yet since not all symbol declarations may have been
5263 (grammar_midrule_action): Likewise.
5264 Don't record whether the midrule's $$ has been used yet since actions
5265 haven't been translated yet.
5266 Record the midrule's parent rule and its RHS index within the parent
5268 (grammar_current_rule_action_append): Don't translate the action yet
5269 since not all symbol declarations may have been parsed yet and, thus,
5270 warnings about types for $$, $n, @$, and @n can't be reported yet.
5271 (packgram): Translate the action and invoke grammar_rule_check now that
5272 all symbol declarations have been parsed.
5273 * src/scan-code.l (handle_action_dollar): Now that this is invoked
5274 after parsing the entire grammar file, the symbol list here in the case
5275 of a midrule is actually the midrule's empty RHS, so reference its
5276 parent rule's RHS where necessary.
5277 On the other hand, now that you can already know it's a midrule, you
5278 aren't forced to think $$ has the same type as its parent rule's $$.
5279 (handle_action_at): In the case of a midrule, reference the parent rule
5281 * src/symlist.c (symbol_list_new): Initialize new midrule-related
5283 (symbol_list_length): Now that this is invoked after all rules have
5284 been parsed, a NULL symbol (rather than a NULL symbol list node)
5285 terminates a rule. symbol_list_print already does this correctly.
5286 * src/symlist.h (symbol_list.midrule_parent_rule,
5287 symbol_list.midrule_parent_rhs_index): New members so that midrules can
5288 remember their relationships with their parents.
5289 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
5290 fixed by the above patch.
5291 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
5293 (Unused values): ... this old test case and...
5294 (Unused values before symbol declarations): ... this new test case.
5295 This one is the same as `Unused values' except that all symbol
5296 declarations appear after the rules in order to catch the rest of the
5297 errors fixed by the above patch.
5299 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5302 * src/reader.c (current_rule): Declare it static since it's no longer
5303 used outside this file.
5304 (grammar_current_rule_action_append): Remove redundant arguments from
5305 translate_rule_action invocation.
5306 * src/reader.h (current_rule): Remove this unused extern.
5307 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
5308 * src/scan-code.l (translate_rule_action): Likewise.
5310 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
5312 Clean up yesterday's patch.
5313 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
5315 * src/reader.c (grammar_current_rule_action_append): ... here for
5316 consistency with grammar_current_rule_symbol_append.
5317 * tests/regression.at (Braced code in declaration in rules section):
5318 Make yyerror and yylex static as usual.
5320 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
5322 Fix bug that mistakes braced code in a declaration in the rules section
5323 to be a rule action. Mentioned at
5324 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
5325 * src/scan-gram.l: Move midrule action detection from the start of the
5326 scanning of any braced code to...
5327 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
5328 action. For readability, use $2 and @2 rather than the equivalent
5330 * tests/regression.at (Braced code in declaration in rules section):
5331 New test to catch the error fixed by the above patch.
5333 Work on code readability some.
5334 * src/scan-code.l (current_rule): Get rid of this misleading and
5335 redundant declaration: it's actually extern'ed in reader.h.
5336 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
5337 translate_action): Add a rule argument and use it instead of the global
5339 (translate_rule_action): This already receives current_rule through an
5340 argument, so pass it on to translate_action instead of assigning
5341 current_rule to current_rule.
5342 (translate_symbol_action, translate_code): Pass rule = NULL to
5345 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
5347 Rename %before-definitions to %start-header and %after-definitions to
5348 %end-header. Don't use these declarations to separate pre-prologue
5349 blocks from post-prologue blocks. Add new order-independent
5350 declarations %before-header and %after-header as alternatives to the
5351 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
5352 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
5353 * NEWS (2.3+): Update for these changes.
5354 * data/glr.c (b4_before_definitions): Update to...
5355 (b4_start_header): ... this.
5356 (b4_after_definitions): Update to...
5357 (b4_end_header): ... this.
5358 * data/glr.cc: Likewise.
5359 * data/lalr1.cc: Likewise.
5360 * data/yacc.c: Likewise.
5361 * doc/bison.texinfo (The prologue): Update names, and replace remaining
5362 prologue blocks with %*-header declarations.
5363 (Calc++ Parser): Likewise.
5364 (Decl Summary): Update names.
5365 (Table of Symbols): Update description.
5366 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
5367 (PERCENT_END_HEADER): ... this.
5368 (PERCENT_BEFORE_DEFINITIONS): Update to...
5369 (PERCENT_START_HEADER): ... this.
5370 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
5371 (declaration): Update token names and m4 macro names.
5372 When parsing %end-header and %start-header, invoke translate_code
5373 before muscle_code_grow, and no longer set global booleans to remember
5374 whether these declarations have been seen.
5375 Parse new %after-header and %before-header.
5376 * src/reader.c (before_definitions, after_definitions): Remove.
5377 (prologue_augment): Accept a new bool argument to specify whether to
5378 augment the pre-prologue or post-prologue.
5379 * src/reader.h (before_definitions, after_definitions): Remove these
5381 (prologue_augment): Add new bool argument.
5382 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
5383 (PERCENT_END_HEADER): ... this.
5384 (PERCENT_BEFORE_DEFINITIONS): Update to...
5385 (PERCENT_START_HEADER): ... this.
5386 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
5387 * tests/actions.at (Printers and Destructors): Update names.
5389 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
5391 Add comparison operators for C++ location classes. Discussed at
5392 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
5393 * data/c++.m4 (b4_define_location_comparison): New boolean %define
5394 declaration indicating whether filename_type has an operator==. If
5395 filename_type is `std::string', it defaults to `1', `0' otherwise.
5396 * data/location.cc: Iff b4_define_location_comparison is `1', add
5397 operator== and operator!= for class position and for class location.
5400 * src/scan-action.l: Remove unused file.
5401 * src/symtab.c (symbol_printer_set): Use printer_location not
5402 destructor_location.
5403 * src/symtab.h (struct symbol): Replace incorrect source comment for
5405 * tests/input.at (Incompatible Aliases): Update output with correct
5408 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
5410 Don't put the pre-prologue in the header file. For the yacc.c code
5411 file and the glr.c header and code files, move the pre-prologue before
5412 the token definitions. Add new %before-definitions and
5413 %after-definitions to declare code that will go in both the header file
5414 and code file. Discussed at
5415 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
5416 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
5418 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
5419 * NEWS (2.3+): Describe these changes.
5420 * data/glr.c (b4_pre_prologue): Move from within to before...
5421 (b4_shared_declarations): ... this.
5422 Add new b4_before_definitions before b4_token_enums.
5423 Add new b4_after_definitions at the end.
5424 * data/glr.cc (b4_pre_prologue): Replace with...
5425 (b4_before_definitions): ... this in the header file.
5426 (b4_after_definitions): New near the end of the header file.
5427 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
5428 code file right before including the header file.
5429 (b4_before_definitions): New in the previous position of
5430 b4_pre_prologue in the header file.
5431 (b4_after_definitions): New near the end of the header file.
5432 * data/yacc.c: Clean up some m4 quoting especially in the header file.
5433 (b4_token_enums_defines): In the code file, move to right before
5434 YYSTYPE for consistency with the header file.
5435 (b4_before_definitions): New right before b4_token_enums_defines in
5436 both the header and code file.
5437 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
5438 header and code file.
5439 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
5440 of prologues for %union dependencies.
5441 (Decl Summary): In %defines description, mention the effect of
5442 %before-definitions and %after-definitions on the header file.
5443 (Calc++ Parser): Forward declare driver in a %before-definitions rather
5444 than in the pre-prologue so that make check succeeds.
5445 (Table of Symbols): Add entries for %before-definitions and
5447 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
5448 %before-definitions.
5449 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
5450 (declaration): Parse those declarations and append to
5451 b4_before_definitions and b4_after_definitions, respectively.
5452 * src/reader.c (before_definitions, after_definitions): New bools to
5453 track whether those declarations have been seen.
5454 (prologue_augment): Add to the post-prologue if %union,
5455 %before-definitions, or %after-definitions has been seen.
5456 * src/reader.h (before_definitions, after_definitions): New extern's.
5457 * src/scan-gram.l: Scan the new declarations.
5458 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
5459 prologue block in a %before-definitions or a %after-definitions based
5460 on whether the %union is declared.
5461 * tests/regression.at (Early token definitions with --yacc, Early token
5462 definitions without --yacc): Move tests for token definitions into the
5463 post-prologue since token names are no longer defined in the
5466 2006-06-20 Akim Demaille <akim@epita.fr>
5468 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
5469 (symbol_get): Use it.
5470 * src/parse-gram.y: Use it.
5472 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
5474 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
5475 build succeeds when configured with --enable-gcc-warnings.
5477 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5479 * src/parse-gram.y (char_name): New function.
5480 (CHAR, STRING, string_content): For %printer, properly escape.
5481 (ID): Prefer fputs to fprintf.
5482 (id): Reindent to be consistent with other rules.
5483 Properly quote char.
5485 The Translation Project changed its way of publishing translations
5486 to maintainers. I haven't received any responses to my request
5487 for supporting the old way, or for documenting the new way. I
5488 have modified 'bootstrap' to use screen scraping
5489 (in this case, HTML scraping). This is unreliable and inelegant,
5490 but I don't see any better way. Yuck.
5491 * bootstrap (TP_URL, WGET_COMMAND): New vars.
5492 (get_translations): New function, which uses HTML scraping to
5493 deduce locations of latest translations.
5494 Use this function to grab both bison and bison-runtime .po files.
5495 Don't bother priming the pump for the runtime-po domain any more,
5496 as it's now translated better than bison is.

5500 * src/scan-gram.l: No longer "parse" things after `%union' until
5501 `{'. Rather, return a single "%union" token.
5502 No longer make symbols: return strings, and leave the conversion
5503 to symbols to the parser.
5504 (SC_PRE_CODE, token_type): Remove.
5505 * src/parse-gram.y (%union): New field `character'.
5508 (ID, ID_COLON): Now that the scanner no longer makes them
5509 identifiers, adjust all uses to invoke symbol_get.
5510 (id_colon): New, wraps the conversion from string to symbol.
5511 (%union): Accept a possible union_name.
5512 (symbol): Now can be a char.
5513 * data/c.m4 (b4_union_name): Leave a default value.
5514 * data/glr.c, data/yacc.c: Use it.
5516 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
5518 For associating token numbers with token names for "yacc.c", don't use
5519 #define statements unless `--yacc' is specified; always use enum
5520 yytokentype. Most important discussions start at:

5530 on token name definitions.
5531 * src/getargs.c (usage): Capitalize `Yacc' in English.
5532 * src/output.c (prepare): Define b4_yacc_flag.
5533 * tests/regression.at (Early token definitions): Test that tokens names
5534 are defined before the pre-prologue not just before the post-prologue.
5535 Remove this test case and copy to...
5536 (Early token definitions with --yacc): ... this to test #define's.
5537 (Early token definitions without --yacc): ... and this to test enums.
5539 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
5541 * NEWS: Reword the post-2.3 change to not be so optimistic about
5542 removing the old "look-ahead" spelling.
5543 Update previous look-ahead/lookahead change reports.
5544 * REFERENCES: look-ahead -> lookahead (since that's
5545 what he actually wrote).
5546 * doc/refcard.tex: look ahead -> lookahead,
5547 look-ahead -> lookahead
5549 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
5551 For consistency, use `lookahead' instead of `look-ahead' or
5552 `look_ahead'. Discussed starting at

5629 Bison without installing the yacc script.
5631 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5633 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
5634 and yytext if they're already #define'd.
5635 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
5636 * src/scan-code-c.c: ... here.

5643 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
5645 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
5646 loc argument as it shadows a global.
5647 * src/scan-gram.l: Remove stray comma that prevents boundary_set
5650 * src/.cvsignore: Add scan-code.c.
5652 2006-06-07 Akim Demaille <akim@epita.fr>
5654 * src/scan-gram.l: Move the "add a trailing ; to actions" code
5656 * src/scan-code.l: here.

5664 2006-06-06 Akim Demaille <akim@epita.fr>
5666 Extract the parsing of user actions from the grammar scanner.
5667 As a consequence, the relation between the grammar scanner and
5668 parser is much simpler. We can also split "composite tokens" back
5670 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
5671 * src/scan-gram.l (add_column_width, adjust_location): Move to and
5673 * src/location.h, src/location.c (add_column_width)
5674 (location_compute): these.
5675 Fix the column count: the initial column is 0.
5676 (location_print): Be robust to ending column being 0.
5677 * src/location.h (boundary_set): New.
5678 * src/main.c: Adjust to scanner_free being renamed as
5680 * src/output.c: Include scan-code.h.
5681 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
5683 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
5684 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
5685 which is now, again, a separate token.
5686 Adjust all dependencies.
5687 Whereever actions with $ and @ are used, use translate_code.
5688 (action): Remove this nonterminal which is now useless.
5689 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
5690 (grammar_current_rule_action_append): Use translate_code.

5697 (YY_DECL): Rename as...
5699 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
5700 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
5701 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
5702 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
5703 Move these declarations, and...

5707 * src/scan-gram.l (rule_length, rule_length_overflow)
5708 (increment_rule_length): Remove.
5709 (last_braced_code_loc): Rename as...
5710 (gram_last_braced_code_loc): this.
5711 Adjust to the changes of the parser.
5712 Move all the handling of $ and @ into...
5713 * src/scan-code.l: here.
5714 * src/scan-gram.l (handle_dollar, handle_at): Remove.

5727 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5729 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5730 Use Akim's wording from
5731 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
5733 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5735 Between Bison releases, manually append `+' to the previous Bison
5736 release number, and use that as a signal to automatically print the
5737 ChangeLog's CVS Id keyword from --version. Discussed starting at
5738 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
5739 * ChangeLog: Add Id header.
5740 * configure.ac (AC_INIT): Append `+' to `2.3'.
5741 * src/.cvsignore: Add revision.c.
5742 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
5743 (BUILT_SOURCES): Add revision.c.
5744 (revision.c): New target rule. This file defines a new global variable
5745 named revision. It initializes it with either the Id from ChangeLog
5746 or, if VERSION doesn't contain `+', with the empty string.
5747 * src/getargs.c (version): Print the value of revision.
5748 * src/revision.h: Extern revision.
5750 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5752 * NEWS: Version 2.3.
5753 * configure.ac (AC_INIT): Likewise.
5755 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5757 * data/glr.c (YYRECOVERING): Define to be a function-like macro
5758 with no arguments, not as an object-like macro. This is for
5759 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
5760 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
5761 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
5764 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
5766 * src/getargs.c (usage): Back out yesterday's modification of the
5767 --help output so that we don't have to wait for translation before
5770 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5772 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
5773 Problem reported by Akim Demaille.
5775 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
5777 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5779 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5781 * data/yacc.c (yy_reduce_print): Omit trailing white space in
5782 generated source code. Problem reported by Frans Englich in
5783 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
5785 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
5787 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
5788 shell, not within 'make', so that 'make' by an ordinary builder
5789 (using GNU make) does not worry about configuring gzip. This also
5790 works around a bug reported independently by Keith Thompson and by
5791 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
5792 stderr rather than stdout, messing up the build logs.
5794 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5796 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
5797 to make sure that YYID will never be unused. This fixes a 'make
5798 maintainer-check' failure caused by the recent changes to the 'Trivial
5799 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
5801 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
5803 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5805 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
5806 state before an empty RHS is always resolved here. Only the location
5807 of that state is guaranteed to be resolved, and that's enough. This
5808 fixes the remaining bug reported by Derek M. Jones in
5809 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5810 * tests/glr-regression.at (Uninitialized location when reporting
5811 ambiguity): Test the above case.
5812 Also, the embedded comments in this test case claim it checks the case
5813 of an empty RHS that has inherited the initial location. However, the
5814 corresponding LHS was already resolved, so yyresolveLocations didn't
5815 actually have reason to modify it. Fix this by forcing
5816 nondeterministic operation at the beginning of the parse.
5818 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5820 * data/c.m4 (b4_yy_symbol_print_generate):
5821 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
5822 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
5823 of the bugs reported today by Derek M Jones in
5824 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5825 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
5826 defined to be a type name without parens or brackets.
5827 (Location Type): Similarly for YYLTYPE.
5828 * tests/regression.at (Trivial grammars): Put in a test for this
5829 bug that will be caught by 'make maintainer-check' (though not,
5830 alas, by 'make check' unless your compiler is picky).
5832 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5834 * NEWS: Version 2.2.
5835 * configure.ac (AC_INIT): Likewise.
5837 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
5839 * data/glr.c (yyreportTree): Make room in yystates for the state
5840 preceding the RHS. This fixes the segmentation fault reported by Derek
5842 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
5843 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
5844 to the user. Reported for yyreportTree by Derek M. Jones later in the
5846 * THANKS: Add Derek M. Jones.
5847 Update my email address.
5848 Fix typo in Steve Murphy's name.
5850 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5852 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
5853 checking against YYLAST that caused the parser to miss a potential
5854 alternative in its diagnostic.
5855 Problem reported by Maria Jose Moron Fernandez in
5856 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
5857 * data/lalr1.cc (yysyntax_error_): Likewise.
5858 * data/yacc.c (yysyntax_error): Likewise.
5859 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
5860 tokens, in case we run into an older C compiler.
5861 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
5862 Use them to check for the off-by-one error fixed above.
5864 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
5865 YYSIZE_T, not size_t.
5866 * tests/regression.at (Trivial grammars): New test, to catch
5867 the error fixed by the above patch.
5869 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5871 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
5873 Reported by Steve Murphy.
5875 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5877 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
5878 * data/glr.cc: b4_location_flag is now b4_locations_flag.
5880 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5882 Implement --trace=m4.
5883 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
5884 * src/output.c (output_skeleton): When set, pass -dV to m4.
5886 Factor the handling of flags in m4.
5887 * src/output.c (prepare): Rename the muscle names debug, defines,
5888 error_verbose to debug_flag, defines_flag, error_verbose_flag.
5889 * data/c.m4: Adjust.
5890 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
5891 Use b4_define_flag_if to define other b4_FLAG_if macros.
5892 (b4_location_if): As a consequence, rename as...
5893 (b4_locations_if): this, for consistency.
5894 Adjust all the skeletons.
5896 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5898 * etc/bench.pm: Shorten bench names.
5900 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5902 * src/output.h, src/output.c (error_verbose): Move to...
5903 * src/getargs.h, src/getargs.c: here.
5905 Adjust dependencies.
5907 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5909 * data/c.m4 (b4_copyright): Put the special exception for Bison
5910 skeletons here, so we don't have to put it in each skeleton. All
5911 uses changed. Suggested by Akim Demaille. Also, wrap the
5912 copyright notice, in case it is longer than 80 columns. Replace
5913 comma by newline after title.
5915 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5917 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
5918 incompatibility, not a bug. Mention that it wasn't fixed as of
5921 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
5923 * examples/extexi: Enforce the precedence of concatenation over
5925 Reported by Tommy Nordgren.
5927 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
5929 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
5930 with the member "token".
5931 Reported by Martin Nylin.
5933 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
5935 * data/glr.c: Switch to Bison 2.2 special-exception language in
5936 the copyright notice. Use more-regular format for titles and
5938 * data/glr.cc: Likewise.
5939 * data/location.cc: Likewise.
5940 * data/yacc.cc: Likewise.

5946 * data/glr.cc: Remove dead code.
5948 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5950 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
5951 that variable and the line breaks the bootstrap. Problem reported
5952 by Juan M. Guerrero.
5954 2006-04-24 Akim Demaille <akim@lrde.epita.fr>

5962 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
5964 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
5966 Reported by Mickael Labau.
5967 * tests/input.at (Torturing the Scanner): Test it.
5969 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
5971 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
5972 Problem reported by Bob Rossi.
5974 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
5976 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
5977 and didn't really work.
5978 For the index, use @ifnotinfo, not @iftex.
5979 Minor cleanups of spacing and terminology.
5981 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
5983 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
5984 of AT_NAME_PREFIX when %name-prefix is not used.
5986 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
5988 Apply --prefix to C++ skeletons too: they change the namespace.
5989 The test suite already exercize these cases.
5990 * data/c++.m4 (b4_namespace): New.
5991 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
5992 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
5993 * data/yacc.c, data/glr.c: Remove a useless `[]'.
5994 * doc/bison.texinfo: Document it.
5995 (Option Cross Key): Use @multitable in all formats. It looks
5996 nicer, even in TeX outputs.
5997 (Rules): Use the same code whatever the output type is.
5998 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
5999 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
6000 * tests/calc.at: Use it, instead of hard coding `yy'.

6004 * TODO: Remove dead items.
6006 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
6008 * doc/FAQ: Remove, merged into...
6009 * doc/bison.texinfo (FAQ): this.
6010 * doc/Makefile.am (EXTRA_DIST): Adjust.
6012 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
6014 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
6016 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
6017 * doc/bison.texinfo (Calc++ Scanner): Use it.
6019 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
6021 Fix two nits reported by twlevo, plus one more that I discovered.
6023 * src/assoc.h (assoc_to_string): Give a name to the arg, as
6024 this is the usual Bison style.
6025 * src/location.h (location_print): Likewise.
6027 * src/reader.h (token_name): Likewise.
6029 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
6031 Fix some nits reported by twlevo.
6032 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
6033 and "POSIX". Use more-modern syntax for URLs. Mention C++
6034 and ask for Java. Don't hardwire OS version numbers. Add
6036 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
6037 * src/conflicts.c (solved_conflicts_obstack): Now static.
6039 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
6041 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
6042 page. Say "you can use it" not "you may use it" as on the web page;
6043 we're describing capabilities not granting permission.
6045 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
6047 * data/glr.c (yyresolveLocations): Rename local variables to avoid
6048 shadowing warnings. Use usual patter for iterating through RHS.
6049 * tests/glr-regression.at
6050 (Uninitialized location when reporting ambiguity):
6051 Modify yylex so that it uses its argument, rather than trying
6052 to rely on ARGSUSED (which doesn't work for gcc with warnings).
6053 const char -> char const.
6055 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
6056 Don't use tabs inside commands; it messes up 'ps'.
6057 Problem reported by twlevo.
6059 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
6061 * tests/glr-regression.at (Uninitialized location when reporting
6062 ambiguity): New test case.
6063 * data/glr.c (yyresolveLocations): New function, which uses
6065 (yyresolveValue): Invoke yyresolveLocations before reporting an
6067 * doc/bison.texinfo (Default Action for Locations): Note
6068 YYLLOC_DEFAULT's usage for ambiguity locations.
6069 (GLR Semantic Actions): Cross-reference those notes.
6071 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
6073 * tests/glr-regression.at (Leaked semantic values when reporting
6074 ambiguity): Remove unnecessary union and type declarations.
6075 (Leaked lookahead after nondeterministic parse syntax error): New test
6077 * data/glr.c (yyparse): Check for zero stacks remaining before
6078 attempting to shift the lookahead so that you don't lose it.
6080 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6082 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
6083 * tests/glr-regression.at (Leaked semantic values when reporting
6084 ambiguity): New test case.
6085 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
6086 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
6087 now unnecessary yystackp parameter.
6088 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
6089 destructors can be called.
6091 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
6092 in existing testcases.
6094 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6096 Don't leak semantic values for parent RHS when a user action cuts the
6097 parser, and clean up related code a bit.
6098 * tests/glr-regression.at (Leaked merged semantic value if user action
6099 cuts parse): Rename to...
6100 (Leaked semantic values if user action cuts parse): ... this. Add check
6101 for leaked parent RHS values.
6102 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
6103 between an unresolved state (non-empty chain of semantic options) and
6104 an incomplete one (signaled by an empty chain).
6105 (yyresolveStates): Document the interface. Move all manipulation of a
6106 successfully or unsuccessfully resolved yyGLRState to...
6107 (yyresolveValue): ... here so that yyresolveValue always leaves a
6108 yyGLRState with consistent data and thus is easier to understand.
6109 Remove the yyvalp and yylocp parameters since they are always just
6110 taken from the yys parameter. When reporting a discarded merged value
6111 in debugging output, note that it is incompletely merged. Document the
6113 (yyresolveAction): If resolving any of the RHS states fails, destroy
6114 them all rather than leaking them. Thus, as long as user actions are
6115 written to clean up the RHS correctly, yyresolveAction always cleans up
6116 the RHS of a semantic option. Document the interface.
6118 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
6120 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
6121 led to a segmentation fault in GNU Pascal. Problem reported
6124 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
6126 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
6127 mid-rule action inside a nonterminal symbol in order to declare a
6128 destructor for its semantic value.
6130 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
6132 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !

6134 __cplusplus && ! defined _STDLIB_H && !
6135 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
6136 defined free))]: Include <stdlib.h> rather than rolling our own
6137 declarations of malloc and free, to avoid problems with
6138 incompatible declarations (using 'throw') C++'s stdlib.h. This
6139 should fix Debian bug 340012

6147 * configure.ac (AC_INIT): Bump version number.
6149 2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
6151 * NEWS: Version 2.1a.
6152 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
6153 since C99 requires this.
6155 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
6157 * m4/c-working.m4: New file.
6158 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
6160 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
6162 * Makefile.maint: Merge from coreutils.
6164 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
6166 More portability fixes for problems summarized by Nelson H. F. Beebe.
6168 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
6169 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
6170 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
6171 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this

6177 More portability fixes for problems summarized by Nelson H. F. Beebe.
6179 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
6180 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
6182 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
6183 nodist_PROGRAMS, since we don't need to actually compile the
6184 example if we're just doing a plain 'make'. This avoids bothering
6185 the installer unnecessarily about problems due to weird C++
6188 2006-02-06 Paul Eggert <eggert@cs.ucla.edu>
6190 More portability fixes for problems summarized by Nelson H. F. Beebe.
6192 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
6193 than #include "...", and compile with -I'.'. The old method was
6194 not portable, according to Posix and the C standard, and it does
6195 not work with Sun C 5.7, where previous #line directives affect
6196 the working directory used in later #include "..." directives.

6207 '#include <map>' works and that you can apply ++ to iterators.
6209 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
6211 Work around portability problems summarized by Nelson H. F. Beebe in
6212 <http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.
6214 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
6215 that '#include <string>' works.
6217 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
6218 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
6219 "warning: sorry: semantics of inline function static data `const
6220 unsigned char translate_table[262]' are wrong (you'll wind up with
6223 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
6224 or, xor to not_, and_, or_, and xor_, respectively. This works
6225 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
6226 random system header somewhere that includes the equivalent of
6229 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
6230 -E" works; it apparently doesn't work with PathScale EKO Compiler
6233 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
6235 During deterministic GLR operation, user actions should be able to
6236 influence the parse by changing yychar. To make this easier to fix and
6237 to make glr.c easier to evolve in general, don't maintain yytoken in
6238 parallel with yychar; just compute yytoken when needed.
6239 * tests/glr-regression.at (Incorrect lookahead during deterministic
6240 GLR): Check that setting yychar in a user action has the intended
6242 * data/glr.c (yyGLRStack): Remove yytokenp member.
6243 (yyclearin): Don't set *yytokenp.
6244 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
6245 yychar rather than *yytokenp to determine the current lookahead.
6246 Compute yytoken locally when needed.
6247 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
6250 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
6251 after `--report' documentation.
6253 2006-01-30 Paul Eggert <eggert@cs.ucla.edu>

6259 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
6261 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
6262 all the test at once. This makes the output easier to read in the
6265 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
6266 got from <http://bro-ids.org/download.html>. The bug is that
6267 when two actions appeared in succession, the second one was
6268 scanned before the first one was added to the grammar rule
6269 as a midrule action. Bison then output the incorrect warning
6270 "parse.y:905.17-906.36: warning: unused value: $3".
6271 * src/parse-gram.y (BRACED_CODE, action): These are no longer
6272 associated with a value.
6273 (rhs): Don't invoke grammar_current_rule_action_append.
6274 (action): Invoke it here instead.
6275 * src/reader.c (grammar_midrule_action): Now extern.
6276 (grammar_current_rule_action_append): Don't invoke
6277 grammar_midrule_action; that is now the scanner's job.
6278 * src/reader.h (last_string, last_braced_code_loc):
6279 (grammar_midrule_action): New decls.
6280 * src/scan-gram.l (last_string): Now extern, sigh.
6281 (last_braced_code_loc): New extern variable.
6282 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
6283 rule already has an action.
6284 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
6285 * tests/input.at (AT_CHECK_UNUSED_VALUES):
6286 Add some tests to check that the above changes fixed the bug.
6288 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
6290 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
6291 All used changed. Check whether the symbol has a destructor,
6292 not whether it is typed.
6293 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
6294 that the values are still reported as unused. All line numbers

6311 user can override the types.

6313 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
6314 (union yyalloc.yyss): Use yytype_int16 rather than short.
6316 (yysigned_char): Remove.
6317 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
6318 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.

6335 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
6338 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>
6340 * Makefile.cfg (local-checks-to-skip): Add changelog-check,
6341 since we don't want to insist on a version number at the start
6342 of the changelog every time.
6343 * Makefile.maint: Sync from coreutils a bit better.

6529 (Actions): Mention look-ahead usage of yylval.
6530 (Actions and Locations): Mention look-ahead usage of yylloc.
6531 (Special Features for Use in Actions): Add YYEOF entry and mention it
6532 in the yychar entry.
6533 In the yychar entry, remove mention of the local yychar case (pure
6534 parser) since this is irrelevant information when writing semantic
6535 actions and since it's already discussed in `Table of Symbols' where
6536 yychar is otherwise described as an external variable.
6537 In the yychar entry, don't call it the `current' look-ahead since it
6538 isn't when semantic actions are deferred.
6539 In the yychar and yyclearin entries, add note about deferred semantic
6541 Add yylloc and yylval entries discussing look-ahead usage.
6542 (Look-Ahead Tokens): When discussing yychar, don't call it the

6565 members to store the current lookahead to be used by the deferred
6567 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
6568 from which the RHS is taken. Set the lookahead members of the new
6569 yySemanticOption according to the lookahead status for stack yyk.

6571 yyaddDeferredAction.
6572 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
6573 members of yySemanticOption before invoking yyuserAction, and then set

6581 char value < 128 in main.
6582 (Incorrect lookahead during deterministic GLR): New test case.
6583 (Incorrect lookahead during nondeterministic GLR): New test case.
6585 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6587 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept

6597 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
6599 * data/glr.c (yyresolveValue): When merging semantic options, if at
6600 least one user action succeeds but a later one cuts the parse, then
6601 destroy the semantic value before returning rather than leaking it.
6602 (yyresolveStates): If a user action cuts the parse and thus
6603 yyresolveValue fails, ignore the (unset) semantic value rather than
6604 corrupting the yyGLRState, and empty the semantic options list since
6605 the user actions should have called all necessary destructors.
6606 Simplify code with YYCHK.
6607 * tests/glr-regression.at (Corrupted semantic options if user action
6608 cuts parse): New test case.
6609 (Undesirable destructors if user action cuts parse): New test case.
6610 Before applying any of this patch, this test case never actually failed
6611 for me... but only because the corrupted semantic options usually

6655 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain

6657 not require a diagnostic when the grammar uses extensions.
6659 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
6661 Warn about dubious constructions like "%token T T".
6663 * src/symtab.h (struct symbol.declared): New member.

6877 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

6906 * tests/sets.at (Accept): Fix typos in regular expression used to
6907 sed out the final state number.
6909 Work around portability problem on Solaris 10: flex-generated
6910 files include <stdio.h> before <config.h>, which messes up
6911 because the latter defines __EXTENSIONS__. Address the problem
6912 by creating two new little files that include <config.h> first,
6913 then include the flex-generated files. Rewrite everyone else
6914 to include <config.h> first, as well.
6915 * lib/timevar.c: Always include "config.h".

6961 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
6962 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
6963 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
6965 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.

6989 * NEWS: Document the following change.
6990 * data/yacc.c: Say "parser skeleton" rather than "file", since
6991 it's no longer just a file.
6992 * data/glr.c: Grant a special exception for C GLR parsers, that
6993 reads like the already-existing exception for C LALR(1) parsers.

6995 * data/lalr1.cc: Likewise.
6996 * data/location.cc: Likewise.

7010 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
7011 We can revert this once things settle down.
7013 * src/conflicts.c (conflicts_print): Don't print file name twice
7014 when %expect fails because there were no conflicts.

7254 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
7256 Undo the parts of the unlocked-I/O change that substituted
7257 putc or puts for printf. This might hurt performance a bit,
7258 but some people prefer the printf style.

7289 Use unlocked I/O for a minor performance improvement on hosts like
7290 GNU/Linux and Solaris that support unlocked I/O. The basic idea
7291 is to use the gnlib unlocked-io module, and to prefer putc and
7292 puts to printf when either will work (since the latter doesn't
7293 come in an unlocked flavor).

7387 2005-10-02 Akim Demaille <akim@epita.fr>
7389 * data/location.cc: New, extract from...
7390 * data/lalr1.cc: here.
7391 (location.hh): Include it after the user prologue, in case the
7392 filename type is defined by the user.
7393 Forward declation location and position before the pre-prologue.
7394 (yyresult_): Rename as...
7395 (yyresult): this, it's a local variable, not an attribute.
7396 * data/Makefile.am (dist_pkgdata_DATA): Adjust.
7398 2005-10-01 Akim Demaille <akim@epita.fr>
7400 * examples/extexi: Restore the #line generation.

7406 * data/lalr1.cc (stack.hh, location.hh): Include earlier.
7407 (parser::token): New, from the moved free definition of tokens.
7408 (parser::semantic_value): Now a full definition instead of an
7409 indirection to YYSTYPE.
7410 (b4_post_prologue): No longer included in the header file, but
7411 in the implementation file.
7412 * doc/bison.texi (C+ Language Interface): Update.
7413 * src/parse-gram.y: Support unary %define.
7414 * tests/actions.at: Define global_tokens_and_yystype for backward
7415 compatibility until we update the tests.
7416 * tests/calc.at: Idem.
7417 (first_line, first_column, last_line, last_column): Define for lalr1.cc
7418 to simplify the code.
7420 2005-09-29 Paul Eggert <eggert@cs.ucla.edu>
7422 Port to SunOS 4.1.4, which lacks strtoul and strerror.
7423 Ah, the good old days! Problem reported by Peter Klein.
7424 * bootstrap (gnulib_modules): Add strerror, strtoul.
7425 * lib/.cvsignore: Add strerror.c, strtol.c, strtoul.c
7426 * m4/.cvsignore: Add strerror.m4, strtol.m4, strtoul.m4.
7428 2005-09-29 Akim Demaille <akim@epita.fr>

7432 (YYERROR_VERBOSE_IF): Remove.
7433 (yyn_, yylen_, yystate_, yynerrs_, yyerrstatus_): Remove as
7434 parser members, replaced by...
7435 (yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
7437 (yysyntax_error_): Takes the state number as argument.
7438 (yyreduce_print_): Use the argument yyrule, not the former
7441 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
7443 * bootstrap (gnulib_modules): Add verify.
7444 * lib/.cvsignore: Add verify.h.

7450 2005-09-21 Paul Eggert <eggert@cs.ucla.edu>
7452 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
7453 local variables whose names begin with 'yy'.
7454 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
7455 Trivial changes from Joel E. Denny.
7457 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
7459 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
7460 don't use alloca any more.
7462 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
7463 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
7464 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
7465 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
7466 to match yacc.c, to test more hosts.
7468 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
7470 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
7471 doesn't affect behavior.
7472 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
7474 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
7475 This works a bit better with glibc, if user code has already included
7477 * doc/bison.texinfo (Bison Parser): Document that users can't
7478 arbitrarily use malloc and free for other purposes. Document
7479 that <alloca.h> and <malloc.h> might be included.
7480 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
7481 user must declare alloca.

7490 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
7492 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
7493 (YYSTACK_ALLOC_MAXIMUM): Use it.
7494 (yysyntax_error): New function.
7495 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
7496 multiple syntax errors are reported, and alloca is being used.
7497 Instead, reallocate buffers twice as big each time, so that
7498 we waste at most half the allocated memory. Start with a small
7499 (128-byte) buffer that will suffice in most cases anyway.
7500 Use yysyntax_error to do most of the work.
7502 * doc/bison.texinfo (Error Reporting, Table of Symbols):
7503 yynerrs is the number of errors reported, not the number of
7506 * tests/glr-regression.at (Duplicated user destructor for lookahead):
7507 Mark it as expected to fail.
7508 Cast result of malloc; problem reported by twlevo@xs4all.nl.
7509 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
7510 Don't start user-code symbols with "yy", to avoid name space problems.
7512 2005-09-19 Akim Demaille <akim@epita.fr>
7514 Remove the traits, failed experiment.
7515 It never proved useful, and anyway because of the current
7516 definition, it was not possible to have several specialization of
7517 this traits, making it useless.
7518 * data/lalr1.cc (yy:traits): Remove.
7519 Inline its definitions in the parser class.
7521 2005-09-19 Akim Demaille <akim@epita.fr>

7543 * src/output.c (prepare): Likewise.
7544 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
7545 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
7546 is not defined. This is an awful hack, but it's enough for now.
7547 All callers changed.
7548 * tests/glr-regression-at (make_value): Args are const pointers now,
7549 to avoid GCC warning.
7550 (Duplicated user destructor for lookahead): New test. Currently
7551 skipped. It fails on my host but I'm not sure it'll always fail.
7553 2005-09-16 Akim Demaille <akim@epita.fr>
7555 * src/symtab.h (struct symbol): Declare the printer and destructor
7556 as const, to avoid accidental calls to free.
7557 (symbol_destructor_set, symbol_printer_set): Adjust.
7558 * src/symtab.c: Adjust.
7560 2005-09-16 Akim Demaille <akim@epita.fr>
7562 * data/c.m4 (b4_token_enums): New.
7563 (b4_token_defines): Rename as...
7564 (b4_token_enums_defines): this.
7565 (b4_token_defines): New, output only the #defines.
7566 * data/yacc.c, data/glr.c: Adjust.
7567 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
7568 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
7571 2005-09-16 Akim Demaille <akim@epita.fr>
7573 * data/lalr1.cc (yylex_): Remove, inline its code.
7574 (yyreport_syntax_error_): Remove, replaced by...
7575 (yysyntax_error_): this which returns a string and leaves to the
7576 caller the call to the users' error function.
7577 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
7578 Move from members of the parser object...
7579 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
7580 to local variables of the parse function.
7582 2005-09-16 Akim Demaille <akim@epita.fr>
7584 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
7585 since it's in Bison's name space.
7587 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
7589 * data/glr.c (yyresolveValue): Add default case to pacify
7590 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
7592 * NEWS: Document when yyparse started to return 2.
7593 * doc/bison.texinfo (Parser Function): Document when yyparse
7596 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
7597 (b4_filename_type): Renamed back from b4_file_name_type. All uses
7599 (class position): file_name -> filename (reverting). All uses changed.
7601 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
7603 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
7604 do anything if $@ exists. This reverts part of the 2005-07-07
7607 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
7609 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
7610 contains obsolete information and isn't worth distributing as a
7611 separate file anyway.
7612 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
7613 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
7614 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
7615 (yyparse): Abort if user code uses longjmp to throw an unexpected
7618 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
7620 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
7621 Suggested by twlevo@xs4all.nl.
7623 * data/glr.c (YYCHK1): Do not assume YYE is in range.
7624 This avoids a diagnostic from gcc -Wswitch-enum.
7625 Problem reported by twlevo@xs4all.nl.
7627 * doc/bison.texinfo: Don't use "filename", as per GNU coding
7628 standards. Use "file name" or "file" or "name", depending on
7630 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
7631 not to hack/foo.tab.c.
7632 (Calc++ Top Level): 2nd arg of main is not const.
7633 * data/glr.c: b4_filename -> b4_file_name.
7634 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

7651 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
7653 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
7656 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7658 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
7659 All uses changed. Invoke user destructor after an error during a
7660 split parse (trivial change from Joel E. Denny).
7662 * tests/glr-regression.at
7663 (User destructor after an error during a split parse): New test case.
7664 Problem reported by Joel E. Denny in:
7665 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
7667 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7669 * README-cvs: Give URLs for recommended tools.
7670 Mention Gzip version problem, and bootstrapping issues.
7671 Remove troubleshooting section, as it's somewhat obsolete.
7673 * bootstrap (no_cache): New var, to accommodate different wget
7674 variants. Use it instead of '-C off'. Problem reported by
7677 * data/glr.c (yydestroyStackItem): New function.
7678 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
7679 debugging information. Problem reported by Joel E. Denny.
7681 2005-08-25 Akim Demaille <akim@epita.fr>
7683 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
7685 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
7687 * data/glr.c (yyrecoverSyntaxError, yyreturn):
7688 Don't invoke destructor on unresolved entries.
7689 * tests/glr-regression.at
7690 (User destructor for unresolved GLR semantic value): New test case.
7691 Problem reported by Joel E. Denny in:
7692 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
7694 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
7696 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
7698 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
7699 lib-prefix.m4, po.m4.
7701 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
7702 in yydestruct diagnostic, since it might not be an error.
7703 Problem reported by Joel Denny near end of
7704 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
7705 * data/lalr1.cc (yyerturn): Likewise.
7706 * data/yacc.c (yyreturn): Likewise.
7707 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
7709 * src/files.c: Remove obsolete FIXME comment.
7711 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
7712 with the other templates, and to fix bogus run-on messages such
7713 as the one reported at the end of
7714 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
7715 All callers changed to avoid the newline.
7716 (yyprocessOneStack): Output two lines rather than one, to accommodate
7717 the above change. This changes the debug output format slightly.
7719 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
7720 reported by Joel E. Denny in
7721 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
7723 * tests/glr-regression.at (Duplicate representation of merged trees):
7724 New test, from Joel E. Denny in:

7726 * THANKS: Add Joel E. Denny.
7728 * configure.ac (AC_INIT): Bump to 2.0c.
7730 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
7732 * NEWS: Version 2.0b.
7734 * Makefile.am (SUBDIRS): Put examples before tests, so that
7735 "make check" doesn't finish with "All 1 tests passed".
7737 * tests/regression.at (Token definitions): Don't rely on
7738 AT_PARSER_CHECK for data that contains backslashes. It currently
7739 uses 'echo', and 'echo' isn't portable if its argument contains
7740 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
7741 that the byte '\0xff' is not printable in the C locale; it is,
7742 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
7743 not printable, so use '\0x81' to test.
7745 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
7746 version of GCC, since the macro is used with non-GCC compilers.
7748 Fix core dump reported by Pablo De Napoli in
7749 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
7750 * tests/regression.at (Invalid inputs with {}): New test.
7751 * src/parse-gram.y (token_name): Translate type before using
7754 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
7755 the user's name space. All uses changed to __attribute__
7757 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
7758 Add __attribute__ ((__noreturn__)).
7760 * etc/clcommit: Remove. We weren't using it, and it failed
7761 "make maintainer-distcheck".
7762 * Makefile.maint: Merge from coreutils.
7763 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
7764 (syntax-check-rules): Change list of rules as described below.
7765 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

7775 Use grep -n, to make it easier to find violations.
7776 Use CVS_LIST and CVS_LIST_EXCEPT.
7777 (header_regexp, h_re): Remove.
7779 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
7780 (my-distcheck): Use more-modern GCC flags.
7781 (signatures, %.asc): Remove.
7782 (rel-files, announcement): Remove signatures.
7783 Restore old updating code, even though we don't use it, so
7784 that we're the same as coreutils.
7785 (alpha, beta, major): Depend on news-date-check.
7786 Make the upload commands.
7788 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.

7795 * tests/sets.at: Likewise.
7797 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
7798 we comment out the Autoconf version number.
7799 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
7800 it's error-prone and "make maintainer-distcheck" rejects it.
7802 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
7803 Indent calls to "error" to pacify "make maintainer-distcheck",
7804 when the calls are not intended to be translated.
7805 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
7807 * src/Makefile.am (DEFS): Use +=, to pacify
7808 "make maintainer-distcheck".
7809 (bison_SOURCES): Add scan-skel.h.
7810 (sc_tight_scope): New rule, from coreutils.
7812 * src/files.c (src_extension, header_extension):
7813 Now static, not extern.
7814 * src/getargs.c (short_options): Likewise.
7815 * src/muscle_tab.c (muscle_table): Likewise.
7816 * src/parse-gram.y (current_class, current_type, current_prec):
7818 * src/reader.c (grammar_end, previous_rule_end): Likewise.
7819 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
7820 * src/main.c (main): Cast bindtextdomain and textdomain calls to
7821 void, to avoid warning when NLS is disabled.
7822 * src/output.c: Include scan-skel.h.
7823 (scan_skel): Remove decl, since scan-skel.h does this.
7825 Indent calls to "error" to pacify "make maintainer-distcheck".
7826 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
7827 * src/reader.h (gram_end, gram_lineno): New decls to pacify
7828 "make maintainer-distcheck".
7829 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
7830 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
7831 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
7832 (skel_lex_destroy, scan_skel): Move these decls to...
7833 * src/scan-skel.h: New file.
7834 * src/uniqstr.c (uniqstr_assert):
7835 Indent calls to "error" to pacify "make maintainer-distcheck".
7837 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
7840 * tests/torture.at: Revamp to avoid misuse of atoi that
7841 "make maintainer-distcheck" complained about.
7843 * examples/extexi (message): Don't print a message more than once,
7844 and omit line-number decoration that makes Emacs compile think
7845 that informative messages are worth worrying about.
7847 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
7849 * configure.ac: Update version number.
7851 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
7853 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
7854 autogenerated by the maintainer.
7855 * examples/calc++/.cvsignore: Add *.yy.
7857 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
7858 * lib/bitset_stats.c (bitset_stats_init): Likewise.
7859 * lib/bitsetv.c (bitsetv_alloc): Likewise.
7861 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
7863 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
7864 from maintainer-distcheck about casting the argument of 'free'.
7866 * NEWS: Mention recent yytname changes.
7867 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
7869 * bootstrap: For translations that have not yet been upgraded to
7870 the new runtime-po domain, prime the pump by extracting the
7871 relevant strings from the obsolete translations. This code can be
7872 removed once the bison-runtime domain has been translated by each
7875 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
7876 now that token names are already quoted.
7878 Fix problem reported by Anthony Heading.
7879 * data/glr.c (YYTOKEN_TABLE): New macro.
7880 (yytname): Define if YYTOKEN_TABLE.
7881 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
7882 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
7883 (YYERROR_VERBOSE): Define the same way the other skeletons do.
7884 * src/output.c (prepare_symbols): Output token_table_flag.
7886 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
7888 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
7889 again if the first call fails.
7891 * data/glr.c (yytnamerr): New function.
7892 (yyreportSyntaxError): Use it to dequote most string literals.
7893 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
7894 with other skeletons. All uses changed.
7895 (yytnameerr_): New function.
7896 (yyreport_syntax_error): Use it to dequote most string literals.
7897 * data/yacc.c (yytnamerr): New function.
7898 (yyerrlab): Use it to decode most string literals.
7899 * doc/bison.texinfo (Decl Summary, Calling Convention):
7900 Clarify quoting convention of yytname.
7901 * src/output.c (prepare_symbols): Quote all names. This undoes
7902 the 2005-04-17 change, which is now accomplished (mostly) via
7903 changes in the parsers as described above.
7904 * tests/regression.at (Token definitions, Web2c Actions):
7905 Undo most 2005-04-17 change here, too.
7907 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
7909 Fix more problems reported by twlevo@xs4all.nl.
7910 * tests/cxx-type.at: Don't pipe output of ./types through sed to
7911 remove trailing spaces. This loses the exit status of ./types,
7912 and isn't needed since ./types shouldn't be emitting trailing
7914 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
7915 as the stack isn't valid in that case.
7917 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
7918 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
7919 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
7920 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
7922 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
7923 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
7924 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
7927 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
7928 overly-picky compilers that reject 'char *foo = "bar";'.
7930 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
7931 to FILE * parameter, not to stderr. This fixes a typo introduced
7932 in the 2005-07-12 change.
7934 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
7935 warnings from GCC 4.
7937 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
7938 (yyglrShiftDefer, yysplitStack):
7939 Remove unused parameters b4_pure_formals. All uses changed.
7940 (yyglrShift): Remove unused parameters b4_user_formals.
7942 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
7944 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
7946 Destructor cleanups and regularization among the three skeletons.
7947 * NEWS: Document the behavior changes.
7948 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
7949 stack before failing, as the cleanup code will do it for us now.
7950 * data/lalr1.cc (yyerrlab): Likewise.
7951 * data/glr.c (yyparse): Pop everything off the stack before
7952 freeing it, so that destructors get called properly.
7953 * data/lalr1.cc (yyreturn): Likewise.
7954 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
7955 This is more consistent.
7956 * doc/bison.texinfo (Destructor Decl): Mention more reasons
7957 why destructors might be called. 1.875 -> 2.1.
7958 (Destructor Decl, Decl Summary, Table of Symbols):
7959 Some English-language cleanups for %destructor.
7960 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
7961 Add output line for destructor of start symbol.
7962 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
7963 because of that same extra output line.
7965 * NEWS: Document minor wording changes in diagnostics of
7966 Bison-generated parsers.
7967 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
7968 Remove unused formals. All uses changed.
7969 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
7970 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
7971 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
7972 Rename yyoverflowab to yyexhaustedlab.
7973 When memory exhaustion occurs during syntax-error reporting,
7974 report it separately rather than in a single diagnostic; this
7976 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
7977 (Memory Exhausted): Renamed from Parser Stack Overflow.
7978 Revamp wording slightly to prefer "memory exhaustion".
7979 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
7981 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
7983 Add i18n support to the GLR skeleton. Partially fix the C++
7984 skeleton; a C++ expert needs to finish this. Remove debugging
7985 msgids; there's little point to having them translated, since they
7986 can be understood only by someone who can read the
7987 (English-language) source code.
7989 Generate runtime-po/bison-runtime.pot automatically, so that we
7990 don't have to worry about garbage getting in that file. We'll
7991 make sure after the next official release that old msgids don't
7993 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
7995 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
7997 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
7998 Fix typos in explanations of the runtime file.
7999 * bootstrap: Change gettext keyword from YYI18N to YY_.
8000 Use standard Makefile.in.in in runtime-po, since we'll arrange
8001 for backward-compatible bison-runtime.po files in a different way.
8002 * data/glr.c (YY_): New macro, from yacc.c.
8003 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
8004 Translate messages intended for users.
8005 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
8006 the wording in the other skeletons. We don't know that the memory
8008 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
8009 Use same method that yacc.c uses.
8010 Don't translate debugging messages.
8011 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
8012 it doesn't work (yet), and requires C++ expertise to fix.
8013 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
8014 Move defn to a more logical place, to be consistent with other
8016 Don't translate debugging messages.
8017 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
8018 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
8019 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
8020 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
8022 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
8023 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
8025 * tests/glr-regression.at (Badly Collapsed GLR States):
8027 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8028 yylex should return 0 at EOF rather than aborting.
8030 Improve tests for stack overflow in GLR parser.
8031 Problem reported by twlevo@xs4all.nl.
8032 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
8034 (yyStackOverflow): Just longjmp, but with value 2 so that caller
8035 can handle the problem.
8036 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
8037 (yyparse): New local variable yyresult to record the result.
8038 Use result of setjmp to set it, rather than storing itinto
8040 (yyDone): Remove label.
8041 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
8042 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
8043 if YYABORT is used).
8044 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
8045 yyparse status; put status > 1 into diagnostic.
8046 Check that status==2 works.
8047 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
8048 Use exit status 3 for failure to open (which shouldn't happen).
8050 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
8052 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
8053 1 on syntax error; just let yyparse do its thing.
8054 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
8055 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
8056 (Exploding the Stack Size with Alloca):
8057 (Exploding the Stack Size with Malloc):
8058 Expect exit status 2, not 1, since the parser is supposed to blow
8059 its stack. Problem reported by twlevo@xs4all.nl.
8061 * data/glr.c (yyparse): Don't assume that the initial calls
8062 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
8063 Print a stack-overflow message and fail instead.
8064 Initialize the line-number information before creating the stack,
8065 so that the stack-overflow message can report line zero safely.
8067 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
8069 Fix problems reported by twlevo@xs4all.nl.
8070 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
8071 (yyuserMerge): Provide a default case if b4_mergers is empty.
8072 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
8073 * tests/glr-regression.at
8074 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8075 Add casts to pacify C++ compilers.
8076 * tests/glr-regression.at (Improper merging of GLR delayed action
8077 sets): Declare yylex before using it.
8078 * tests/Makefile.am (maintainer-check-g++): Fix a stray
8079 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
8080 test for valgrind; valgrind is independent of g++.
8081 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
8082 for compatibility with POSIX 1003.1-2001 (if running coreutils).
8083 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
8084 Use a destructor, so that we can expand the stack. Change
8085 YYSTYPE to char * so that we can free it. Cast result of malloc.
8087 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8089 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
8090 a valgrind failure. Problem reported by twlevo@xs4all.nl.
8092 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
8094 * PACKAGING: New file, suggested by Bruno Haible and taken from
8095 similar wording in gettext's PACKAGING file.
8096 * NEWS: Mention PACKAGING.
8097 * Makefile.am (EXTRA_DIST): Add PACKAGING.
8099 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
8101 * NEWS: Document recent i18n improvements.
8102 * bootstrap: Get runtime translations into runtime-po.
8103 Create runtime-po files automatically, if possible.
8104 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
8105 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
8106 does not infringe on the user's name space.
8107 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
8108 * doc/bison.texinfo (Internationalization): Revamp the English
8109 and Texinfo syntax a bit, to try to make it clearer.
8110 (Bison Options, Option Cross Key): Mention --print-localedir.
8111 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
8112 YYENABLE_NLS. Quote a bit more.
8113 * runtime-po/.cvsignore: New file.
8114 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
8115 * runtime-po/Rules-quot: Remove; now created by bootstrap.
8116 * runtime-po/quot.sed: Likewise.
8117 * runtime-po/boldquot.sed: Likewise.
8118 * runtime-po/en@quot.header: Likewise.
8119 * runtime-po/en@boldquot.header: Likewise.
8120 * runtime-po/insert-header.sin: Likewise.
8121 * runtime-po/remove-potcdate.sin: Likewise.
8122 * runtime-po/Makevars: Likewise.
8123 * runtime-po/LINGUAS: Likewise.
8124 * runtime-po/de.po: Likewise; we will rely on the translation project
8125 to maintain this, so "bootstrap" should get it.
8126 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
8128 * src/main.c (main): Bind the bison-runtime domain, too.
8130 2005-07-12 Bruno Haible <bruno@clisp.org>
8132 * data/yacc.c: Include <libintl.h> when NLS is enabled.
8133 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
8134 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
8135 * runtime-po: New directory.
8136 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
8137 $(DOMAIN).pot-update rule, so that old messages are never dropped.
8138 * runtime-po/Rules-quot: New file, copied from po/.
8139 * runtime-po/quot.sed: Likewise.
8140 * runtime-po/boldquot.sed: Likewise.
8141 * runtime-po/en@quot.header: Likewise.
8142 * runtime-po/en@boldquot.header: Likewise.
8143 * runtime-po/insert-header.sin: Likewise.
8144 * runtime-po/remove-potcdate.sin: Likewise.
8145 * runtime-po/Makevars: New file.
8146 * runtime-po/POTFILES.in: New file.
8147 * runtime-po/LINGUAS: New file.
8148 * runtime-po/bison-runtime.pot: New file.
8149 * runtime-po/de.po: New file.
8150 * m4/bison.m4: New file.
8151 * Makefile.am (SUBDIRS): Add runtime-po.
8152 (aclocaldir, aclocal_DATA): New variables.
8153 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
8155 * src/getargs.c (usage): Document --print-localedir option.
8156 (PRINT_LOCALEDIR_OPTION): New enum item.
8157 (long_options): Add --print-localedir option.
8158 (getargs): Handle --print-localedir option.
8159 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
8160 (Internationalization): New section.
8162 2005-07-12 Akim Demaille <akim@epita.fr>
8164 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
8165 for consistency with the rest of the code.
8166 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
8169 2005-07-12 Akim Demaille <akim@epita.fr>
8171 * src/parse-gram.y: Use %printer instead of YYPRINT.
8173 2005-07-12 Akim Demaille <akim@epita.fr>
8175 * src/symtab.h, src/symtab.c (symbol_print): New.
8176 * src/symlist.h, src/symlist.c (symbol_list_print): New.

8179 2005-07-12 Akim Demaille <akim@epita.fr>
8181 * data/glr.c (b4_syncline): Fix (swap) the definitions of
8182 b4_at_dollar and b4_dollar_dollar.
8184 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
8186 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
8187 and Pennello's paper.
8189 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
8191 * data/yacc.c (yyparse): Undo previous patch. Instead,
8192 set yylsp[0] and yyvsp[0] only if the initial action
8193 sets yylloc and yylval, respectively.
8195 * data/yacc.c (yyparse): In the initial action, set
8196 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
8197 This avoids the use of undefined variables if the initial
8198 action does not set yylloc and/or yylval.
8200 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8202 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
8203 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
8204 Remove from CVS. These files are automatically generated.
8205 * examples/extexi: Clarify that this file is now part of Bison,
8206 not GNU M4, and that it works with any POSIX-compatible Awk.
8207 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
8208 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
8209 so that we also get calc++-parser.yy. Geneate it.
8210 Use $(AWK), not gawk, since any conforming Awk will do.
8211 Put comment before action, since older 'make' can't handle comment
8213 $(BUILT_SOURCES): List all built sources, not just some of them.
8214 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
8215 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
8216 $($(calc_sources_generated)): Remove unnecessary test for existence
8217 of target. (This had a shell syntax error anyway; a stray "x".)
8218 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
8220 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
8222 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
8223 implied by the other modules.
8225 2005-07-06 Akim Demaille <akim@epita.fr>
8227 Bind examples/calc++ to the package.
8228 * examples/calc++/Makefile: Remove, replaced by...

8230 * examples/calc++/test: Remove input.
8231 * examples/calc++/compile: Remove.
8232 * examples/Makefile.am: New.
8233 * configure.ac, Makefile.am: Adjust.
8234 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
8236 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
8238 * data/glr.c (yyFail): Drastically simplify; since the format argument
8239 never had any % directives, we can simply pass it to yyerror.
8240 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
8241 be modified later, as that is the usual style in glr.c.
8242 Problems reported by Paul Hilfinger.
8244 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
8245 and size overflow errors.
8246 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
8247 in case the user prolog sets feature-test macros like _GNU_SOURCE.
8248 (YYSIZEMAX): New macro.
8249 (yystpcpy): New function, taken from yacc.c.
8250 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
8251 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
8252 so that we don't have to maintain their signatures.
8253 (yyFail): Check for buffer overflow, by using vsnprintf rather
8254 than vsprintf. Allocate a bigger buffer if possible.
8255 Report an error if buffer allocation fails.
8256 (yyStackOverflow): New function.
8257 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
8258 the initialization was successful. It might fail if storage was
8260 (yyexpandGLRStack): Add more checks for storage allocation failure.
8261 Use yyStackOverflow to report failures.
8262 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
8263 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
8264 Don't assume stack number fits in int.
8265 (yysplitStack): Check for storage allocation failure.
8266 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
8267 can print diagnostics on storage allocation failure. All callers
8269 (yyresolveValue): Use yybool for boolean.
8270 (yyreportSyntaxError): Check for size-calculation overflow.
8271 This code is taken from yacc.c.
8272 (yyparse): Check for storage allocation errors when allocating
8275 2005-07-05 Akim Demaille <akim@epita.fr>
8277 Extract calc++ from the documentation.
8278 * doc/bison.texinfo (Calc++): Add the extraction marks.
8279 * examples/extexi: New, from the aborted GNU Programming 2E.
8280 Separate the different paragraph of a file with empty lines.
8281 * examples/Makefile: Use it to extract the whole calc++ example.

8306 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
8308 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
8309 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
8310 which stems from the 2005-05-27 patch.
8312 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
8314 * data/glr.c: Modify treatment of unused parameters to permit use
8315 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
8317 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
8319 Fix infringement on user name space reported by Janos Zoltan Szabo.

8325 Translate the various messages.
8327 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
8329 Fix infringement on user name space reported by Bruno Haible.
8330 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
8331 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
8332 the user's name space.
8333 (alloca): Include <stdlib.h> to get it, if it's not built in.
8334 (YYMALLOC, YYFREE): Define only if needed.
8335 (malloc, free): Declare, but only if needed, as this infringes on
8336 the user name space.
8338 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
8340 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
8341 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
8343 * lib/ebitset.c (min, max): Undef before defining.
8344 * lib/vbitset.c (min, max): Likewise.
8345 * lib/subpipe.c (create_subpipe): Save local variables in case
8346 vfork clobbers them.

8356 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
8358 * bootstrap: Remove workaround for problem I encountered with
8359 gettext 0.14.1; it seems to be fixed now.

8363 * NEWS: Version 2.0a.
8365 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
8366 the previous change.
8368 Various maintainer cleanups.
8369 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
8370 conftest*, for benefit of CVS commands run at the same time as
8371 "configure". Add build-aux, since "bootstrap" now creates it and
8373 * Makefile.cfg (move_if_change): Remove.
8374 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
8375 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

8383 this is now the recommended name.
8384 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
8385 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
8386 ylwrap. These files now go into build-aux.
8387 * config/move-if-change: Remove.
8388 * config/prev-version.txt: Bump from 1.75 to 2.0.
8390 * bootstrap: Add stdio-safer, unistd-safer modules.

8394 fopen-safer.c, stdio-safer.h, unistd-safer.h.
8395 * lib/subpipe.c: Include "unistd-safer.h".
8396 (create_subpipe): Make sure all the newly-created
8397 file descriptors are > 2, so that diagnostics don't
8398 get sent down them (which might cause Bison to hang, in theory).
8399 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
8400 * src/files.c (xfopen): Use fopen_safer, not fopen.
8402 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
8403 yesterday's yacc.c fix.
8405 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>

8411 * data/yacc.c (yyabortlab): Don't call destructor, and
8412 don't set yychar to EMPTY.
8413 (yyoverflowlab): Don't call destructor.
8414 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
8415 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
8416 since we no longer output the message "discarding lookahead token
8419 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8421 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
8422 fix a small glitch in debugging output.
8423 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
8424 after YY_SYMBOL_PRINT where needed.
8426 (struct yyGLRState): Add some comments.
8427 (struct yySemanticOption): Add some comments.
8428 (union yyGLRStackItem): Add comment.

8475 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
8477 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
8478 Problem reported by Ralf Menzel.
8480 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8482 * tests/actions.at: Test that stack overflow invokes destructors.
8483 From Marcus Holland-Moritz.
8484 * data/yacc.c (yyerrlab): Move the code that destroys the stack
8486 (yyreturn): to here. That way, destructors are called properly
8487 even if the stack overflows, or the user calls YYACCEPT or
8488 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
8489 (yyoverflowlab): Destroy the lookahead.
8491 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
8493 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
8495 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
8497 * NEWS: Bison-generated C parsers no longer quote literal strings
8498 associated with tokens.
8499 * src/output.c (prepare_symbols): Don't escape strings,
8500 since users don't want to see C escapes.
8501 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
8503 * tests/input.at (Torturing the Scanner): Likewise.
8504 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
8506 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
8508 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
8509 the data size is known to be too small and we can't increase it.
8510 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
8512 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
8514 * src/parse-gram.y: Include quotearg.h.
8515 (string_as_id): Quote $1 before using it as a key, since the
8516 lexer no longer quotes it for us.
8517 (string_content): Don't strip quotes, since lexer no longer
8519 * src/scan-gram.l: Include quotearg.h.
8521 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
8522 a key, since the rest of the lexer doesn't quote it.
8523 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
8524 * tests/regression.at (Token definitions): Check for backslashes
8527 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
8528 (YYSIZE_T): Define to unsigned long int when using an older compiler.
8529 (yyparse): Revamp code to generate long syntax error message, to
8530 make it easier to translate, and to avoid problems with arithmetic
8531 overflow. Change "virtual memory" to "memory" in diagnostic, since
8532 we don't know whether the memory is virtual.
8534 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8536 * NEWS: Bison-generated C parsers now use the _ macro to
8538 * data/yacc.c (_) [!defined _]: New macro.
8539 All English strings wrapped inside this macro.
8540 * doc/bison.texinfo (Bison Parser): Document _.
8541 * po/POTFILES.in: Include src/parse-gram.c, since it now
8542 includes translateable strings that parse-gram.y doesn't.
8544 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
8546 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
8547 reverting the 2004-10-11 change to this function.
8548 (symbol_check_alias_consistency): Don't call symbol_type_set
8549 if the type name is already correct.
8550 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
8552 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
8554 * tests/regression.at (Token definitions): Don't use a token named
8555 c, as that generates a "#define c ..." that runs afoul of buggy
8556 stdlib.h that uses the identifier c as a member of struct
8557 drand48_data. Problem reported by Horst Wente.
8559 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
8561 * bootstrap: Change translation URL from
8562 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
8563 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
8564 redirection glitches. Problem reported by twlevo@xs4all.nl.
8566 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
8568 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
8569 after operands; POSIX says this isn't portable for the c99 command.
8571 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
8573 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
8574 immediately if a data overrun has occurred; this may help us track
8575 down what may be a spurious failure on MacOS.
8577 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
8579 Respond to problems reported by twlevo@xs4all.nl.
8581 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
8583 * src/vcg.h: Comment fix.
8584 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
8585 (G_CMAX): Change to -1 instead of INT_MAX.
8587 * data/yacc.c (yyparse): Omit spaces before #line.
8589 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
8591 * src/tables.c (state_number_to_vector_number): Put it inside an
8592 "#if 0", since it's not currently used. Problem reported by
8595 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
8597 * src/output.c (escaped_output): Renamed from
8598 escaped_file_name_output, since we now use it for symbol tags as
8599 well. All uses changed.
8600 (symbol_destructors_output, symbol_printers_output):
8601 Escape symbol tags too.
8602 Problem reported by Matyas Forstner in
8603 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
8605 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
8607 * src/output.c (user_actions_output, token_definitions_output,
8608 symbol_destructors_output, symbol_printers_output): Likewise.
8609 * src/reader.c (prologue_augment): Likewise.
8610 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
8612 * src/vcg.c (output_edge): Don't quote linestyle arg.
8613 Problem reported by twlevo@xs4all.nl.
8615 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
8617 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
8618 example, reported by Derek M Jones. Also, make the example even
8619 more outrageous, to better illustrate how bad the problem is.
8621 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
8623 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
8624 putsym. Typo reported by Sebastian Piping.
8626 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8628 * doc/bison.texinfo (Language and Grammar): some -> same
8629 (Epilogue): int he -> in the
8630 Typos reported by Sebastian Piping via Justin Pence.
8632 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8634 * tests/glr-regression.at (Improper handling of embedded actions
8635 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
8636 embedded actions and $-N in GLR parsers", work around an Autoconf bug
8637 with dollar signs in test names.
8638 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
8639 for a similar reason.
8641 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8643 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
8644 wants to redefine G_VIEW.
8646 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
8648 * src/vcg.c (get_view_str): Remove case for normal_view.
8649 Problem reported by twlevo@xs4all.nl.
8651 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
8653 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
8654 Problem reported by twlevo@xs4all.nl.
8656 * doc/bison.texinfo: Change @dircategory from "GNU programming
8657 tools" to "Software development". Requested by Richard Stallman
8660 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
8662 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
8663 Problem reported by twlevo@xs4all.nl.
8665 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8667 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
8668 keyword; it's not needed with modern compilers, and it doesn't
8669 affect correctness with older compilers. Suggested by
8672 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
8674 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
8675 gcc -Wswitch-default.
8676 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
8677 * data/yacc.c (yyparse): Likewise.
8679 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
8681 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
8682 already. Let config.h define any nonstandard values.
8684 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
8686 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
8687 for the benefit of slower hosts. Problem reported by
8690 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
8692 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
8693 being defined and not used.
8694 * data/lalr1.cc (yyparse): Likewise.
8695 Use "if (false)" rather than "if (0)".
8697 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
8699 * TODO: Mention that we should allow NUL bytes in tokens.
8701 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>

8708 * src/getargs.c (version): Happy new year; update overall
8709 program copyright date from 2004 to 2005.
8711 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
8712 Problem reported by Hans Aberg.
8713 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
8714 (Output file names.): Add a test for the case when standard output
8717 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
8719 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
8720 to fix an oversight in the Bison 2.0 manual.
8722 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
8724 * NEWS: Version 2.0. Reformat the existing news items since
8725 1.875, so that related items are grouped together.
8726 * configure.ac (AC_INIT): Bump version to 2.0.
8727 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
8729 * tests/torture.at (Exploding the Stack Size with Alloca): Set
8730 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
8731 otherwise, we're not testing alloca. Unfortunately there's no
8732 simple way to consult HAVE_ALLOCA here.
8734 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
8737 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
8738 hand. This avoids a warning about comparing int to size_t when
8739 GCC warnings are enabled.
8741 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
8743 * NEWS: Bison-generated parsers no longer default to using the
8744 alloca function (when available) to extend the parser stack, due
8745 to widespread problems in unchecked stack-overflow detection.
8746 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
8747 responsibility to set it to a positive value. This lets the user
8748 specify a value that is not a preprocessor constant.
8749 * data/yacc.c (YYMAXDEPTH): Likewise.
8750 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
8751 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
8752 to be a compile-time constant. However, explain the constraints on it.
8753 Also, explain the constraints on YYINITDEPTH.
8754 (Table of Symbols): Explain that alloca is no longer the default.
8755 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
8758 * doc/bison.texinfo (Location Default Action): Mention that n must
8759 be zero when k is zero. Suggested by Frank Heckenbach.
8761 2004-12-22 Akim Demaille <akim@epita.fr>
8763 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
8764 (parser::state_type, parser::semantic_type, parser::location_type):
8765 Private, not public.
8766 (parser::parse): Return ints, not bool.
8767 Returning a bool introduces a problem: 0 corresponds to false, and
8768 it seems weird to return false on success. Returning true changes
8769 the conventions for yyparse.
8770 Alternatively we could return void and send an exception.
8771 There is no clear consensus (yet?).
8772 (state_stack, semantic_stack, location_stack): Rename as...
8773 (state_stack_type, semantic_stack_type, location_stack_type): these.
8774 Private, not public.

8778 2004-12-21 Akim Demaille <akim@epita.fr>
8780 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
8782 2004-12-21 Akim Demaille <akim@epita.fr>
8784 Don't impose std::string for filenames.
8786 * data/lalr1.cc (b4_filename_type): New.
8787 (position::filename): Use it.
8788 (parser.hh): Move the inclusion of stack.hh and location.hh below
8789 the user code, so that needed headers for the filename type can be
8791 Forward declare them before the user code.
8792 * tests/Makefile.am (check-local, installcheck-local): Pass
8793 TESTSUITEFLAGS to the TESTSUITE.
8795 2004-12-20 Akim Demaille <akim@epita.fr>
8797 Use more STL like names: my_class instead of MyClass.
8799 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
8800 (SemanticStack, SemanticType, StateStack, StateType)
8801 (TokenNumberType, Stack, Slice, Traits, Parser::location)
8802 (Parser::value): Rename as...
8803 (location_stack, location_type, rhs_number_type, semantic_stack)
8804 (semantic_type, state_stack, state_type, token_number_type, stack)
8805 (slice, traits, parser::yylloc, parser::yylval): these.
8807 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
8809 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
8811 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
8812 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
8814 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
8816 Remove uses of 'short int' and 'unsigned short int'. This raises
8817 some arbitrary limits. It uses more memory but nowadays that's
8818 not much of an issue.
8820 This change does not affect the generated parsers; that's a different
8821 task, as some users will want to conserve memory there.
8823 Ideally we should use size_t to represent all object counts, and
8824 something like ptrdiff_t to represent signed differences of object
8825 counts; but that will require more code-cleanup than I have the
8826 time to do right now.
8828 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
8829 Use size_t, not int or short int, to count objects.
8830 * src/closure.c (nritemset, closure): Likewise.

8845 * src/tables.c (vector_number, tally, action_number,

8847 * src/output.c (muscle_insert_short_int_table): Remove.
8849 2004-12-17 Akim Demaille <akim@epita.fr>
8851 * data/lalr1.cc: Extensive Doxygenation.
8852 (error_): Rename as...
8853 (error): this, since it is visible to the user.
8855 (Parser::message): Now an automatic variable from...
8856 (Parser::yyreport_syntax_error_): here.
8857 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
8859 * tests/input.at: Escape $.
8861 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
8863 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
8864 Parenthesize rhs to avoid obscure problems with mistakes like
8865 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
8866 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
8867 b4_rhs_location): Likewise.
8868 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
8869 b4_rhs_location): Likewise.
8871 2004-12-16 Akim Demaille <akim@epita.fr>
8873 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
8874 yacc.c: be sure to stay within yycheck_.
8875 * tests/actions.at: Re-enable C++ tests.
8877 2004-12-16 Akim Demaille <akim@epita.fr>
8879 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
8882 2004-12-16 Akim Demaille <akim@epita.fr>
8884 Use #define to handle the %name-prefix.
8886 * data/glr.c, data/yacc.c: Comment changes.
8887 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
8888 so that one can refer to yylex in the parser file, and have it
8889 renamed, as is the case with other skeletons.
8891 2004-12-16 Akim Demaille <akim@epita.fr>
8893 Move lalr1.cc internals into yy*.

8913 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
8915 Fix some problems reported by twlevo at xs4all.
8916 * src/symtab.c (symbol_new): Report an error if the input grammar
8917 contains too many symbols. This is better than calling abort() later.
8918 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
8919 (struct node, struct graph):
8920 Rename member expand to stretch. All uses changed.
8921 (struct graph): Remove member layoutalgorithm. All uses removed.

8930 Add more Doxygen comments.
8931 (symprint_, stack_print_, reduce_print_, destruct_, pop)
8932 (report_syntax_error_, translate_): Rename as...
8933 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)

8936 2004-12-15 Akim Demaille <akim@epita.fr>
8938 * data/lalr1.cc (lex_): Rename as...
8940 Move the trace here.
8941 Take the %name-prefix into account.
8942 Reported by Alexandre Duret-Lutz.
8944 2004-12-15 Akim Demaille <akim@epita.fr>
8946 Simplify the C++ parser constructor.
8948 * data/lalr1.cc (debug_): Rename as...
8949 (yydebug_): so that the parser's internals are always in the yy*
8952 (b4_parse_param_decl): Remove the leading comma as it is now only
8953 called as unique argument list.
8954 (Parser::Parser): Remove the constructor accepting a location and
8955 an initial debugging level.
8956 Remove from the other ctor the argument for the debugging level.
8957 (debug_level_type, debug_level, set_debug_level): New.
8959 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
8962 2004-12-15 Akim Demaille <akim@epita.fr>
8964 Remove b4_root related material: failure experiment
8965 (which goal was to allow to derive from a class).
8967 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
8968 definitions and uses.
8970 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
8972 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
8973 not 2, since it's not portable to subtract 1 from the start of an
8974 array. The new item 0 is never set or used. All uses changed.
8976 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
8977 the default definition of YYLLOC_DEFAULT. Problem reported
8978 by Frank Heckenbach.
8980 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
8982 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
8983 the normal case and one for the error case. Just use the
8984 first one uniformly. Problem reported by Frank Heckenbach.
8985 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
8986 use exactly the same macro in both places.
8987 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
8988 so that the normal-case YYRHSLOC works for the error case too.
8990 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
8991 (YYLLOC_DEFAULT): Use the same macro as glr.c.
8992 * doc/bison.texinfo (Location Default Action): Don't claim that
8993 we have an array of locations. Use the same macro for both glr
8994 and lalr parsers. Mention YYRHSLOC. Mention what happens when
8997 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>

9006 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
9008 * src/scan-skel.l: Include "complain.h", for "fatal".
9010 * src/relation.h (relation_print, relation_digraph):
9011 Relation sizes are of type relation_node, not size_t (this is
9012 merely a doc fix, since the two types are equivalent).
9013 (relation_transpose): Relation sizes are of type relation_node,
9015 * src/relation.c: Likewise.
9016 (top, infinity): Now of type relation_node, not int.
9017 (traverse, relation_transpose): Use relation_node, not int.
9019 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
9020 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
9021 (yyparse): Remove unused local introduced in 2004-10-25 patch.
9023 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
9024 specifying whether the test should be skipped. Use it tp
9025 specify that the [%defines %skeleton "lalr1.cc"] tests currently
9026 fail on some hosts, and should be skipped.
9028 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
9030 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
9031 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
9032 unless otherwise specified below.
9034 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
9035 to allocate kernel_base, kernel_items, kernel_size, since
9036 they needn't be initialized to 0.
9037 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
9038 * src/closure.c (new_closure): Likewise, for itemset.

9054 (goto_actions): Likewise for state_count.
9055 (pack_table): Likewise for base, pos, check.
9056 (tables_generate): Likewise for width.
9058 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
9059 for initial core. Just have a separate core, so we needn't worry
9060 about whether kernel_size and kernel_base are initialized.
9062 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
9063 kernel_size, kernel_items): Remove unnecessary initialization.

9068 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
9069 conflrow, conflict_table, conflict_list, table, check):
9072 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
9073 This is because all callers pass unsigned int.
9074 * src/closure.h (new_closure): Likewise.
9076 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
9077 (build_relations): Initialize includes[i] in all cases.
9078 * src/reader.c (packgram): Always initialize rules[ruleno].prec
9079 and rules[ruleno].precsym. Initialize members in order.

9082 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
9084 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
9085 conflict_list[0] was always 0, but now it isn't initialized.
9087 * src/table.c (table_grow): When conflict_table grew, the grown
9088 area wasn't cleared. Fix this.
9090 * lib/.cvsignore: Add strdup.c, strdup.h.
9091 * m4/.cvsignore: Add strdup.m4.
9093 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
9095 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
9096 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
9097 GOTO_NUMBER_MAXIMUM, since we occasionally compute
9098 ngotos + 1 without checking for overflow.
9099 (build_relations): Use END_NODE, not -1, to denote end of edges.
9100 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
9101 build_relations): Use goto_number, not int, for goto numbers.

9106 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
9107 of #defining from yystype.
9108 Don't typedef yystype, C++ does not need it.
9109 This lets it possible to forward declare it as union.
9111 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
9113 * bootstrap (gnulib_modules): Add extensions.
9114 Problem reported by Jim Meyering.

9134 Use it instead of cdebug_.
9135 (Parser::debug_stream, Parser::set_debug_stream): New.
9136 (Parser::symprint_): Define cdebug_ for temporary backward

9151 Problem reported by Frank Heckenbach.
9153 2004-10-25 Akim Demaille <akim@epita.fr>
9155 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
9156 Introduce another definition to address simple location arrays.
9157 (yyGLRStack): New member: yyerror_range.
9158 (yyrecoverSyntaxError, yyparse): Update it.
9159 (yyrecoverSyntaxError): Use it when shifting the error token to
9160 have an accurate range, equivalent to the one computed by both
9161 yacc.c and lalr1.cc.
9162 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
9163 that column numbers start at column 0, as per GNU Coding
9164 Standards, the others tests, and the doc.
9165 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
9166 Adjust to the above change (first column is 0).
9167 And adjust the location of the "<error>", now covering the whole
9170 2004-10-22 Akim Demaille <akim@epita.fr>
9171 and Paul Eggert <eggert@cs.ucla.edu>
9173 Remove some arbitrary limits on goto numbers and relations.
9174 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
9175 initial values, since they're never used.
9176 (set_goto_map): ngotos is now unsigned, so test for overflow
9177 by seeing whether it wraps around to zero.
9178 * src/lalr.h (goto_number): Now size_t, not short int.
9179 (GOTO_NUMBER_MAXIMUM): Remove.
9180 * src/relation.c (relation_print, traverse, relation_transpose):
9181 Check for END_NODE rather than looking at sign.
9182 * src/relation.h (END_NODE): New macro.
9183 (relation_node): Now size_t, not short int.
9185 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
9187 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
9188 keyword, not an identifier. Problem reported by Baron Schwartz in
9189 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
9191 2004-10-11 Akim Demaille <akim@epita.fr>
9193 * src/symtab.c (symbol_check_alias_consistency): Also check
9194 type names, destructors, and printers.
9195 Reported by Alexandre Duret-Lutz.
9196 Recode the handling of associativity and precedence in terms
9197 of symbol_precedence_set.
9198 Accept no redeclaration at all, not even equal to the previous
9200 (redeclaration): New.
9201 Use it to factor redeclaration complaints.
9202 (symbol_make_alias): Don't set the type of the alias, let
9203 symbol_check_alias_consistency do it as for other features.
9204 * src/symtab.h (symbol): Add new member prec_location, and
9206 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.

9209 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
9211 .cvsignore fixes to accommodate gnulib changes,
9212 and the practice of naming build directories "_build".

9214 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
9215 * m4/.cvsignore: Add "*_gl.m4".
9217 2004-10-06 Akim Demaille <akim@epita.fr>
9219 * src/parse-gram.y (add_param): Fix the truncation of trailing
9222 2004-10-05 Akim Demaille <akim@epita.fr>
9224 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
9225 whether the reducion was empty or not. This leaves room to
9226 improve the use of YYLLOC_DEFAULT in such a case.
9227 lalr1.cc is still experimental, so changing this is acceptable.
9228 And finally, there are probably not many users who changed the
9229 handling of locations in GLR, so changing is admissible too.
9231 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
9232 empty reduction, set @$ to an empty location ending the previously
9234 Adjust uses to make sure the code is triggered on empty
9236 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
9237 expected output: empty reductions have empty locations.
9239 2004-09-29 Akim Demaille <akim@epita.fr>
9241 * data/lalr1.cc: Move towards a more standard C++ coding style
9242 for templates: Class < T > -> Class<T>.
9244 2004-09-29 Akim Demaille <akim@epita.fr>
9246 * data/lalr1.cc: Reinstall the former ctor, for sake of
9247 compatibility, but warn it will be removed.
9248 Move towards a more standard C++ coding style (i.e., type *var ->
9251 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
9253 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
9254 since it's less likely to work if NULs are involved in the future.
9256 2004-09-27 Akim Demaille <akim@epita.fr>
9258 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
9260 2004-09-27 Akim Demaille <akim@epita.fr>
9262 * data/lalr1.cc (b4_parse_param_decl_1): New.
9263 (b4_parse_param_decl): Use it to have different names between attribute
9265 (b4_cc_constructor_call): Likewise.
9267 2004-09-24 Akim Demaille <akim@epita.fr>
9269 * src/parse-gram.y (add_param): Strip the leading and trailing
9270 blanks from a formal argument declaration.
9271 (YY_LOCATION_PRINT): New.
9273 2004-09-24 Akim Demaille <akim@epita.fr>
9275 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
9278 2004-09-24 Akim Demaille <akim@epita.fr>
9280 * doc/bison.texinfo (Table of Symbols): Sort.
9282 2004-09-21 Akim Demaille <akim@epita.fr>
9284 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
9285 the useless parentheses.
9286 Suggested by Paul Eggert.
9288 2004-09-20 Akim Demaille <akim@epita.fr>
9290 Let the initial-action act on the look-ahead, and use it for the
9291 "initial push" (corresponding to an hypothetical beginning-of-file).
9292 And let lalr1.cc honor %initial-action.
9294 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
9296 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
9297 (Parser::Parser): Remove the ctor that used to initialize it.
9298 (Parser::parse): Like in the other skeletons, issue the "starting
9299 parse" message before any action.
9300 Honor %initial-action.
9301 Initialize the stacks with the lookahead.
9302 * data/yacc.c: Let $$ and @$ in %initial-action designate the
9304 Push them in the stacks.
9305 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
9307 2004-09-20 Akim Demaille <akim@epita.fr>
9309 * doc/bison.texinfo (Initial Action Decl): New.
9311 2004-09-20 Akim Demaille <akim@epita.fr>
9313 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
9314 clearer criterion to define it.
9315 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
9316 When reducing on an empty RHS, use the latest stacked location as
9318 yylloc is not always available.
9319 * data/glr.c: Likewise.
9320 Also, honor initial-actions.
9322 2004-09-20 Akim Demaille <akim@epita.fr>
9324 * data/yacc.c (YY_LOCATION_PRINT): New.
9325 Define when we know YYLTYPE's structure, i.e., when the default
9326 YYLLOC_DEFAULT is used.
9327 * data/c.m4 (b4_yysymprint_generate): Use it.
9328 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
9329 value of the result.
9330 (error_start_): Replace with...
9331 (error_range_): this location array.
9332 This allows to replace code relying on the implementation of
9333 locations by portable code.
9334 * data/yacc.c (yylerrsp): Replace with...
9335 (yyerror_range): this.
9336 Every time a token is popped, update yyerror_range[0], to have an
9337 accurate location for the error token.
9338 * data/glr.c (YY_LOCATION_PRINT): New.
9339 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
9340 deference a pointer.
9341 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
9342 report the location in %printers.
9344 * src/scan-skel.l: Instead of abort, report error messages to ease
9345 understanding skeleton scanning failures.
9347 2004-09-16 Akim Demaille <akim@epita.fr>
9349 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
9350 (iterator, const_iterator): these, to be more in the C++ spirit.
9351 Also, return reverse iterators so that when displaying the stack
9352 we display its bottom first.
9353 (Parser::stack_print_, Parser::reduce_print_): Match the messages
9355 We should probably use vector here though.
9357 2004-09-16 Akim Demaille <akim@epita.fr>
9359 Have more complete shift traces.
9361 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
9362 to report Shifts instead of ad hoc YYDPRINTF invocations,
9363 including for the error token.
9364 * data/lalr1.cc (symprint_): Output the location.
9365 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
9366 output the location within the %printer.
9367 Activate GLR tests, at least to make sure they compile properly.
9368 They still don't pass though.
9369 * tests/calc.at: Adjust expect verbose output, since now "Entering
9370 state..." is on a different line than the "Shifting" message.
9372 2004-09-08 Akim Demaille <akim@epita.fr>
9374 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
9375 Bison directive from the Bison file to the invocation of this
9376 macro, so that these directives are passed to
9377 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
9378 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
9379 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
9380 the extra Bison directives instead of the whole series.
9381 Change the grammar so that there are recoverable errors, and
9382 unrecoverable errors. Now we can have the parser give up before
9383 consuming the whole input. As a result we now can observe that
9384 the lookahead is freed when needed.
9385 Change the parser source to parse argv[1] instead of a hard coded
9387 Simplify yylex, and give a value and location to EOF.
9388 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
9389 passed directives already coded in the file.
9390 Add some tests to check the location of "error".
9391 For some tests, the C++ parser is correct, and not yacc.c.
9392 For other tests, they provide different, but unsatisfying, values,
9393 so keep the C++ value so that at least one parser is "correct"
9394 according to the test suite.
9395 (Actions after errors): Remove, this is subsumed by the
9396 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
9398 2004-09-06 Akim Demaille <akim@epita.fr>
9400 * data/lalr1.cc: Adjust the indentation of the labels.
9404 2004-09-06 Akim Demaille <akim@epita.fr>
9406 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
9407 argument, an informative message.
9408 Call YY_SYMBOL_PRINT.
9409 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
9410 * data/lalr1.cc (destruct_): Likewise.
9411 In addition, no longer depend on b4_yysymprint_generate and
9412 b4_yydestruct_generate to generate these functions, do it "by
9415 2004-09-03 Akim Demaille <akim@epita.fr>
9417 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
9418 invoked, yydestruct the lookahead.
9419 * tests/calc.at (Calculator $1): Update the expected lengths of
9420 traces: there is an added line for the discarded lookahead.
9421 * doc/bison.texinfo (Destructor Decl): Some rewording.
9422 Define "discarded" symbols.
9424 2004-09-02 Akim Demaille <akim@epita.fr>
9426 * data/lalr1.cc (translate_, destruct_): No reason to be static.
9428 2004-09-02 Akim Demaille <akim@epita.fr>
9430 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
9431 (YYDSYMPRINTF): Rename as...
9432 (YY_SYMBOL_PRINT): this.
9433 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
9435 Use it instead of direct symprint_ calls.
9436 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
9439 2004-09-02 Akim Demaille <akim@epita.fr>
9441 * data/lalr1.cc (b4_yysymprint_generate): New.
9442 (symprint_): New member function, defined when YYDEBUG.
9443 Use it consistently instead of token/nterm debugging output by
9445 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
9446 %printer calls to use cdebug_ when using lalr1.cc.
9448 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
9450 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
9451 with #ifdef YYDEBUG.
9453 2004-08-26 Akim Demaille <akim@epita.fr>
9455 * doc/bison.texinfo (Implementing Loops): Rename as...
9456 (Implementing Gotos/Loops): this.
9458 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
9460 Adjust to latest gnulib.
9461 * bootstrap (gnulib_modules): Add xalloc-die.
9462 Set LC_ALL=C so that file names sort consistently.
9463 Prefer the gnulib copies of gettext.m4, glibc21.m4,
9464 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
9465 uintmax_t.m4, ulonglong.m4.
9466 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
9467 po.m4 since we are now using _gl.m4 instead.
9469 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
9471 * src/scan-action.l: Remove. Scanning of semantic actions is
9472 handled in scan-gram.l.
9474 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
9476 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
9478 * src/location.h (struct): The file member is a uniqstr.
9479 (equal_boundaries): Use UNIQSTR_EQ for comparison.
9481 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
9483 Fix bug with non-%union parsers that have printers or destructors,
9484 which led to a Bison core dump. Reported by Peter Fales in
9485 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
9487 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
9488 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
9489 not to our own type.
9490 * src/output.c (symbol_destructors_output, symbol_printers_output):
9491 Don't assume %union.
9492 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
9493 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
9494 UNION-FLAG. All callers changed.
9495 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
9496 Use type char, not unsigned int, when declaring an array of char;
9497 this lets us remove a cast.
9498 (Printers and Destructors): Add non-%union test cases.
9500 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9502 * doc/bison.texinfo: Minor editorial changes, mostly to the new
9503 GLR writeups. E.g., avoid frenchspacing and the future tense,
9504 change "lookahead" to "look-ahead", and change "wrt" to "with
9507 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9509 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
9510 New sections, split off from the GLR Parsers section. Put the new
9511 Simple GLR Parser near the start of the GLR section, for clarity.
9512 Rewrite connective text.
9514 2004-06-21 Frank Heckenbach <frank@g-n-u.de>

9570 C++ compiler. (trivial change)
9572 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
9574 Spent a few hours checking out which prerequisite versions the
9575 current sources actually require. I went all the way back to
9576 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
9577 a seemingly endless set of combinations of versions more recent
9578 than that. The bottom line is that the current sources require
9579 fairly recent versions of the build tools, and it'll be some work
9581 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
9582 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
9583 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
9584 Add comments explaining why those particular versions are
9587 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
9588 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
9589 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
9591 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
9592 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
9594 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9596 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
9597 0.11.5. Suggested by Bruno Haible.
9598 * bootstrap: Remove gettext version checking.
9600 * doc/bison.texinfo (Decl Summary): Also mention that %union
9601 can depend on prerequisite types. Problem reported by Tim
9604 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9606 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
9607 * README-alpha: Don't tell people not to package this.
9609 * bootstrap: Don't assume $(...) works; use `...` instead.
9610 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
9613 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
9614 put into the -d output file, and mention what to do if YYSTYPE is
9617 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9619 Undo change made earlier today: it caused autopoint to not bring
9620 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
9623 * bootstrap: Check that gettext version matches what's in
9624 configure.ac. Warn users to ignore robots.txt ERROR 404.
9625 * bootstrap: Undo today's earlier change (logged below).
9626 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
9628 The gettext version checking is causing more trouble than it's
9629 curing; remove it. Problem reported by Paul Hilfinger.
9631 * bootstrap: Issue a warning that one can expect a message
9632 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
9633 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
9635 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
9637 Ensure that the C++ compiler used for testing actually works on a
9638 simple test program; if not, skip the C++-related tests. Problem
9639 reported by Vin Shelton in:
9640 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
9642 * m4/cxx.m4: New file.

9649 * data/glr.c (yylloc): Output this macro even if locations are not
9650 being generated, as the GLR parser needs it even in that case.
9651 Problem reported by Troy A. Johnson
9652 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
9654 * configure.ac (AC_INIT): Update to 1.875e.

9662 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
9663 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
9664 lalr1.cc runs afoul of the first, and the last two are no longer
9665 supported by GCC 3.4.0.
9666 * README: Mention GNU m4 1.4 or later; mention m4 patches.
9667 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
9669 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>

9705 * src/.cvsignore: Add *.output.
9707 * src/parse-gram.y: Put copyright notice inside %{ %} so it
9708 gets copied to the output file.
9710 2004-04-28 Paul Eggert <eggert@twinsun.com>
9712 Get files from the gnulib and po repositories, instead of relying
9713 on them being in our CVS. Upgrade to latest versions of gnulib
9716 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
9717 * bootstrap: Bootstrap from gnulib and po repositories.
9718 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
9719 * README-cvs: Document these changes. Remove version numbers from
9720 mentions of build tools, since they change so often. Mention Flex.
9722 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.

9724 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
9725 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
9727 (AC_ISC_POSIX): Remove; we no longer support this
9728 ancient OS, as it gets in the way of latest Autoconf & gnulib.
9729 (AC_HEADER_STDC): Remove: we now assume C89 or better.
9730 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
9731 Do not check for C89 headers, except for locale.h which is used
9732 by the Yacc library and must port to K&R hosts.
9733 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
9734 Do not check for C89 functions, except for setlocale which is
9735 used by the Yacc library.
9736 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
9737 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

9746 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
9747 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
9748 Define to empty, as gnulib.mk will do the rest for us.
9749 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
9751 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
9752 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
9754 * src/files.c: Include gnulib's xstrndup.h.
9756 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
9757 (REALLOC): Use xnrealloc, for likewise.
9758 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
9759 (strnlen, memrchr): Remove decls; functions no longer used.

9782 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
9783 Remove, as these files are now generated automatically
9784 by bootstrap or automake.

9810 support it. (The latest stable gzip doesn't.)
9812 2004-04-27 Paul Eggert <eggert@twinsun.com>
9814 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
9815 case, as stos_ is now used by destructors due to the 2004-02-09
9818 Remove more K&R C support.

9840 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
9842 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
9843 so that this include file can stand alone.
9844 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
9845 does this now. Include subpipe.h first after config.h, to
9846 test whether it can stand alone.
9848 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
9849 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
9852 * tests/synclines.at (%union synch line): Put a dummy member in
9853 the union, because empty unions aren't allowed in C. Caught
9856 2004-04-13 Jim Meyering <jim@meyering.net>
9858 * src/conflicts.c (conflicts_print): Correct format string typo:

9917 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
9919 Use expected_sr_conflicts in place of expected_conflicts.
9920 Warn if expected_rr_conflicts used in non-GLR parser.
9922 * doc/bison.texinfo: Add documentation for %expect-rr.
9924 2004-03-08 Paul Eggert <eggert@gnu.org>
9926 Add support for hex token numbers. Suggested by Odd Arild Olsen in
9927 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.

9958 error_start_ when erroneous token are discarded.
9959 (Parser::parse) <yyerrlab1>: Compute the location of the error
9960 token so that it covers all the discarded tokens.
9961 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
9962 it can be called with `%skeleton "lalr1.cc"', and do that.
9964 2004-02-02 Paul Eggert <eggert@twinsun.com>
9966 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
9967 $(top_srcdir)/lib and ../lib. This fixes a bug reported
9968 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
9969 There's no need to mention top_builddir since Automake does that
9971 (INCLUDES): Remove, as Automake says it's obsolescent.
9972 Contents migrated into AM_CPPFLAGS as described above.
9973 * lib/Makefile.am (INCLUDES): Remove; obsolescent.

9981 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
9983 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
9984 resulting parsers are compilable with C++.
9986 2003-12-23 Paul Eggert <eggert@twinsun.com>
9988 * config/depcomp, config/install-sh: Sync with Automake 1.8.
9989 * src/output.c (output_skeleton): Rename local var.
9990 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
9991 Bison tokens, as this runs afoul of the 2003-10-07 change that
9992 disallowed NUL bytes in character constants or string literals.
9994 * tests/local.at: Require Autoconf 2.59's Autotest.
9995 * tests/testsuite.at: Don't include local.at, since we now assume
9996 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
9998 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
9999 multiple inclusion warnings.

10014 if testsuite doesn't exist.
10016 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
10017 literals, unfortunately.
10018 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
10019 Complain about NUL bytes in character constants or string literals.
10021 2003-10-05 Paul Eggert <eggert@twinsun.com>
10023 * NEWS: Don't document %no-default-prec, as it's still
10025 * doc/bison.texinfo: Document %no-default-prec only if
10026 the defaultprec flag is set. Normally it's not.
10028 2003-10-04 Paul Eggert <eggert@twinsun.com>
10030 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
10031 non-modifiable lvalue, instead of a modifiable one.
10032 * doc/bison.texinfo (Actions): Document that $$ can
10033 be assigned to. Do not claim that $$ and $N are
10034 array element references: user code should not rely on this.
10036 2003-10-01 Paul Eggert <eggert@twinsun.com>
10038 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.

10048 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
10049 * src/print_graph.c (print_graph): Adjust.
10051 2003-09-30 Frank Heckenbach <frank@g-n-u.de>

10072 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
10075 2003-08-26 Akim Demaille <akim@epita.fr>
10077 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
10078 "<\#" to avoid magic from Gnus when posting parts of this script.

10082 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
10083 (Parser::parse): here.
10084 Adjust: nerrs and errstatus is now replaced by...
10085 (Parser::nerrs_, Parser::errstatus_): New.
10087 2003-08-25 Akim Demaille <akim@epita.fr>
10089 * config/announce-gen, Makefile.cfg: New.
10090 * Makefile.am: Adjust.
10091 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
10092 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
10094 2003-08-25 Akim Demaille <akim@epita.fr>
10096 When reducing initial empty rules, Bison parser read an initial
10097 location that is not defined. This results in garbage, and that
10098 affects Bison's own parser. Therefore we need (i) to extend Bison
10099 to support a means to initialize this location, and (ii) to use
10100 this CVS Bison to fix CVS Bison's parser.
10102 * src/reader.h, reader.c (epilogue_augment): Remove, replace
10104 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
10105 * src/parse-gram.y: Adjust.
10106 (%initial-action): New.
10107 (%error-verbose): Since we require CVS Bison, there is no reason
10109 * src/scan-gram.l: Adjust.
10110 * src/Makefile.am (YACC): New, to make sure we use our own parser.
10111 * data/yacc.c (yyparse): Use b4_initial_action.
10113 2003-08-25 Akim Demaille <akim@epita.fr>
10115 * doc/bison.texinfo: Don't promote stdout for error messages.
10117 2003-08-25 Akim Demaille <akim@epita.fr>
10119 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
10120 From Alexandre Duret-Lutz.

10136 2003-08-25 Akim Demaille <akim@epita.fr>
10138 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
10139 error recovery loops. This patch is based on
10140 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
10141 Also, augment the similarity between lalr1.cc and yacc.c.
10142 Note: the locations of error recovery rules are not correct yet.
10144 * data/lalr1.cc: Comment changes to augment the similarity between
10145 lalr1.cc and yacc.c.
10146 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
10147 (yyerrlab1): Remove, but where it used to be (now the bottom part of
10148 yyerrlab), when hitting EOF, pop the whole stack here instead of
10149 merely falling thru the default error handling mechanism.
10150 (yyerrorlab): New label, with the old contents of YYERROR,
10151 plus the following change: pop the stack of rhs corresponding
10152 to the production that invoked YYERROR. That is how Yacc
10153 behaves (required by POSIX).
10154 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
10157 2003-08-25 Akim Demaille <akim@epita.fr>
10159 Tune local.at so that people can "autom4te -l autotest calc.at -o
10160 calc" for instance, to extract a sub test suite.
10162 * tests/testsuite.at: Move the initialization, Autotest version
10163 requirement, and AT_TESTED invocation into...
10164 * tests/local.at: here.
10165 * tests/testsuite.at: Include it for compatibility with Autoconf
10167 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
10170 2003-08-04 Paul Eggert <eggert@twinsun.com>
10172 Rework code slightly to avoid gcc -Wtraditional warnings.
10173 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
10174 The returned value is now stored in *YY0. All callers changed.
10175 * src/output.c (merge_output): Adjust to the above change.
10177 2003-07-26 Paul Eggert <eggert@twinsun.com>
10179 * data/glr.c (YYASSERT): New macro.
10180 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
10181 yyresolveStates, yyprocessOneStack):
10182 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
10183 Derived from a suggestion by Frank Heckenbach.
10185 2003-07-25 Paul Eggert <eggert@twinsun.com>
10187 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
10188 for portability to K&R C (after ansi2knr, presumably). See
10189 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
10190 by Frank Heckenbach, though I have omitted the structure-initialization
10191 part of his glr-knr.diff patch since I recall that the Portable
10192 C Compiler didn't require that change.
10194 Let the user specify how to allocate and free memory.
10195 Derived from a suggestion by Frank Heckenbach in
10196 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
10197 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
10198 All uses of free, malloc, realloc changed to use these macros,
10199 and unnecessary casts removed.
10200 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
10202 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
10204 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
10205 use s.empty() rather than s == "" to test for empty string; see
10206 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
10209 2003-06-25 Akim Demaille <akim@epita.fr>
10211 * config/depcomp, config/install-sh: Update from masters.
10213 2003-06-20 Paul Eggert <eggert@twinsun.com>
10215 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
10216 and return properly parenthesized result.
10217 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
10218 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10219 Remove unnecessary parentheses from uses.
10220 * doc/bison.texinfo (Location Default Action): Describe the
10221 conventions for parentheses.
10223 2003-06-19 Paul Eggert <eggert@twinsun.com>
10225 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
10226 yyreportTree): Do not assume that size_t is the same width as int,
10227 when printing sizes. Print sizes using an unsigned format.
10228 Problem reported by Frank Heckenbach in
10229 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
10231 Port to Forte Developer 7 C compiler.
10232 * data/glr.c (struct YYLTYPE): If locations are not being used,
10233 declare a single dummy member, as empty structs do not conform
10235 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
10236 the Forte Developer 7 C compiler complains that end-of-loop
10237 code is not reached.
10239 2003-06-17 Paul Eggert <eggert@twinsun.com>
10241 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
10242 avoid warnings from picky compilers about redefinition of PARAMS.
10244 2003-06-17 Paul Eggert <eggert@twinsun.com>
10248 * NEWS: Document 1.875b.
10250 * lib/bbitset.h: Do not include config.h; that's the includer's job.
10251 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
10252 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
10253 Don't use 'index' in comments, as it's a builtin fn on some hosts.
10254 * lib/bitset_stats.c: Include gettext.h unconditionally, as
10255 per recent gettext manual's suggestion.
10256 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
10257 Use prototypes, not old-style definitions.
10258 * lib/lbitset.c (lbitset_unused_clear): Likewise.
10259 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
10260 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
10261 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,

10264 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
10265 vbitset_or_and_cmp, vbitset_copy): Likewise.
10267 * lib/libiberty.h: Do not include config.h; that's the includer's job.
10268 Do not include <stdlib.h>.
10269 (PARAMS): Define unconditionally for C89.
10270 (ATTRIBUTE_NORETURN): Remove.
10271 (ATTRIBUTE_UNUSED): Define unconditionally.
10273 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
10274 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
10275 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
10276 * lib/vbitset.c, lib/vbitset.h: New files.
10277 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
10278 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
10281 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
10282 `How Can I Reset @code{yyparse}', since texinfo does not allow
10283 arbitrary @ in node names.
10285 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
10286 shouldn't be needed according to the gettext 0.12.1 documentation
10287 but which seem to be needed anyway: codeset.m4 glibc21.m4
10288 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
10289 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
10290 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
10292 * lib/.cvsignore: Add stdbool.h.
10293 * m4/.cvsignore: Add nls.m4, po.m4.
10295 Upgrade to CVS gnulib.
10296 * stdbool_.h: File renamed from stdbool.h.in.
10297 * configure.ac (AM_STDBOOL_H): Invoke this instead of
10299 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
10300 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
10301 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
10302 (MOSTLYCLEANFILES): New var.
10303 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
10304 (stdbool.h): New rule.
10305 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
10306 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
10307 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
10308 m4/quote.m4: Upgrade to today's gnulib.
10310 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
10311 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
10312 the tests right now.
10313 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
10314 yyerror are declared before use; C99 requires this.
10316 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10318 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
10320 (yyrecoverSyntaxError): Correct the logic for setting and testing
10322 Correct comment on handling EOF.
10323 Allow states with only a default reduction, rather than failing
10324 (I can't quite reconstruct why these were not allowed before).
10326 Fixes to avoid problem that $-N rules in GLR parsers can cause
10327 buffer overruns, corrupting state.
10329 * src/output.c (prepare_rules): Output max_left_semantic_context
10331 * src/reader.h (max_left_semantic_context): New variable declaration.
10332 * src/scan-gram.l (max_left_semantic_context): Define.
10333 (handle_action_dollar): Update max_left_semantic_context.
10334 * data/glr.c (YYMAXLEFT): New definition.
10335 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
10336 (yyresolveAction): Ditto.
10338 Fixes to problems with location handling in GLR parsers reported by
10339 Frank Heckenbach (2003/06/05).
10341 * data/glr.c (YYLTYPE): Make trivial if locations not used.
10342 (YYRHSLOC): Add parentheses, and define only if locations used.
10343 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
10344 locations not used.
10345 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
10346 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
10348 * tests/cxx-type.at: Exercise location information; update tests
10349 to differentiate output with and without locations.
10350 Remove forward declarations of yylex and yyerror---caused errors
10351 because default YYLTYPE not yet defined.
10352 Change semantic actions to compute strings, rather than printing
10353 them directly (to test proper passing of semantics values). Change
10354 output to prefix notation and update test data and expected results.
10355 (yylex): Track locations.
10356 (stmtMerge): Return value rather than printing, and include arguments
10359 2003-06-03 Paul Eggert <eggert@twinsun.com>
10361 Avoid warnings generated by GCC 2.95.4 when Bison is
10362 configured with --enable-gcc-warnings.
10363 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
10364 yy::]b4_parser_class_name[::translate_,
10365 yy::Stack::operator[] (unsigned),
10366 yy::Stack::operator[] (unsigned) const,
10367 yy::Slice::operator[] (unsigned),
10368 yy::Slice::operator[] (unsigned) const):
10369 Rename local vars to avoid warnings.
10370 * tests/glr-regression.at (Improper handling of embedded actions
10371 and $-N in GLR parsers): Remove unused local variable from yylex.
10372 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
10373 (void) as arg when not pure, since we now assume C89 when building
10374 Bison. Pacify GCC by using parameter.
10376 2003-06-02 Paul Eggert <eggert@twinsun.com>
10378 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
10379 yy::Location::lines, yy::Location::columns): Rename arguments
10380 to avoid shadowing; this removes a warning generated by GCC 3.3.
10382 2003-06-01 Paul Eggert <eggert@twinsun.com>
10384 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
10385 to g++, as GCC 3.3 complains if you do it.
10386 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
10387 everything that WARNING_CFLAGS has, except omit warnings
10388 not suitable for C++.
10389 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
10390 * tests/atlocal.in (CXXFLAGS): New var.
10391 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
10393 Fix a GLR parser bug I reported in February; see
10394 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
10395 The problem was that GLR parsers did not conform to the C standard,
10396 because actions like { $1 = $2 + $3; } expanded to expressions
10397 that invoked YYFILL in separate subexpressions, and YYFILL assigned
10398 to a local variable. The C standard says that expressions
10399 like (var = f ()) + (var = f ()) have undefined behavior.
10400 Another problem was that GCC sometimes issues warnings that
10401 yyfill and its parameters are unused.
10403 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
10404 as possibly unused.
10405 (yyfill): New function.
10407 (yyuserAction): Change type of yynormal to bool, so that it matches
10408 the new yyfill signature. Mark it as possibly unused.
10411 Follow up on a bug I reported in February, where a Bison-generated
10412 parser can loop. Provide a test case and a fix for yacc.c. I
10413 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10414 The original bug report is in:
10415 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
10417 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10418 macro's size was becoming unwieldy.
10419 (yyerrlab): Do not discard an empty lookahead symbol, as this
10420 might destroy garbage.
10421 (yyerrorlab): New label, with the old contents of YYERROR,
10422 plus the following change: pop the stack of rhs corresponding
10423 to the production that invoked YYERROR. That is how Yacc
10424 behaves, and POSIX requires this behavior.
10425 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10426 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10427 Define 'alarm' to do nothing if unistd.h is not available.
10428 Add a new rule "exp: '-' error;" to test the above change to
10429 data/yacc.c. Use 'alarm' to abort any test taking longer than
10430 10 seconds, as it's probably looping.
10431 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10432 Also, the new yacc.c generates two fewer diagnostics for an
10435 2003-05-24 Paul Eggert <eggert@twinsun.com>
10437 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
10438 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
10439 This fixes a problem reported by John Bowman when the Compaq/HP
10440 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
10441 -ansi -Wall -gall).
10442 * data/yacc.c (union yyalloc): Likewise.
10443 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
10445 Switch from 'int' to 'bool' where that makes sense.
10447 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,

10471 lbitset_xor_cmp): Likewise.
10472 * lib/bbitset.h: Include <stdbool.h>.

10506 * config/install-sh: Sync from automake 1.7.5.
10508 2003-05-14 Paul Eggert <eggert@twinsun.com>
10510 * src/parse-gram.y (rules_or_grammar_declaration): Require a
10511 semicolon after a grammar declaration, in the interest of possible
10512 future changes to the Bison input language.
10513 Do not allow a stray semicolon at the start of the grammar.
10514 (rhses.1): Allow one or more semicolons after any rule, including
10515 just before "|" as required by POSIX.
10516 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
10519 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
10521 %parse-param support for lalr1.cc.
10523 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
10524 b4_cc_constructor_calls, b4_cc_constructor_call,
10525 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
10527 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
10528 parse-param arguments.
10529 (yy::b4_parser_class_name): Declare instance variables to
10530 hold parse-param arguments.
10531 * tests/calc.at: s/value/semantic_value/ because value clashes
10532 with a member of yy::b4_parser_class_name. Adjust C++ code
10533 to handle %parse-param. Enable %parse-param test in C++.
10535 2003-05-12 Paul Eggert <eggert@twinsun.com>
10537 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
10538 English a bit. Fix fclose typo. Change "const char" to "char
10539 const", and use ANSI C rather than K&R for "main". Suggest
10540 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
10541 and suggest yy_switch_to_buffer.
10543 2003-05-05 Paul Eggert <eggert@twinsun.com>
10545 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
10546 C89. This avoids a diagnostic on compilers that define __STDC__
10547 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
10548 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10550 2003-05-03 Paul Eggert <eggert@twinsun.com>
10552 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
10553 Do not overrun array bounds.
10554 This should fix a bug reported today by Olatunji Oluwabukunmi in
10555 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
10557 2003-04-29 Akim Demaille <akim@epita.fr>
10559 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
10560 * src/getargs.c, src/getargs.h: here, as bool, not int.
10561 (nondeterministic_parser): New.
10562 * src/parse-gram.y, src/scan-gram.l: Support
10563 %nondeterministic-parser.
10564 * src/output.c (prepare): Use nondeterministic_parser instead
10565 of glr_parser where appropriate.
10566 * src/tables.c (conflict_row, action_row, save_row)
10567 (token_actions, token_actions, pack_vector): Ditto.
10569 2003-04-29 Akim Demaille <akim@epita.fr>
10571 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
10573 2003-04-29 Akim Demaille <akim@epita.fr>
10575 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
10576 with %pure-parser and %locations to exercise the patch from Yakov
10579 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
10581 * data/yacc.c: (b4_lex_param): Corrected for the case where
10582 %lex-param is provided and %pure-parser isn't.
10584 2003-04-27 Paul Eggert <eggert@twinsun.com>
10586 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
10587 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
10588 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
10589 if it is not defined.
10590 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
10592 2003-04-26 Paul Eggert <eggert@twinsun.com>
10594 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
10595 Declare to be of type suitable for the ninf value itself, not of
10596 type suitable for the corresponding table, since the latter might
10597 be unsigned but the ninf value might be negative. This fixes a
10598 bug reported by Alexandre Duret-Lutz in
10599 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
10601 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
10602 invokes it. We shouldn't invoke it twice because it will attempt
10603 to put error.o in the archive twice. This fixes a glitch reported
10604 by Martin Mokrejs in
10605 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10607 2003-04-21 Paul Eggert <eggert@twinsun.com>
10609 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
10612 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
10614 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
10615 Fix obvious typo that results in uncompilable GLR parsers
10616 when both %pure-parser and %locations are used. (trivial change)
10618 2003-04-17 Paul Eggert <eggert@twinsun.com>
10620 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
10621 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
10622 Do not insert the expected token via unput, as this runs afoul
10623 of a POSIX-compatibility bug in flex 2.5.31.
10624 All uses changed to BEGIN the parent state,
10625 since we no longer insert the expected token via unput.
10626 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
10627 that is no longer emitted after the above change.
10629 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
10630 the first one. This change is from Paul Hilfinger, and it fixes
10631 regression reported by Werner Lemberg in
10632 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
10634 (resolve_sr_conflict): Don't invoke state_errs_set
10635 unless one or more tokens have been explicitly made errors.
10636 Otherwise, the above change causes Bison to abort.
10638 * tests/existing.at (GNU pic Grammar): New test case, taken from
10641 2003-03-31 Akim Demaille <akim@epita.fr>
10643 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
10645 2003-03-31 Akim Demaille <akim@epita.fr>
10647 * src/output.c (prepare_symbols): Avoid trailing spaces in the
10650 2003-03-31 Akim Demaille <akim@epita.fr>
10652 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
10653 From Paul Hilfinger.
10655 2003-03-29 Akim Demaille <akim@epita.fr>
10657 * m4/error.m4: Do not put under dynamic conditions some code which
10658 expansion is under static control.
10660 2003-03-29 Akim Demaille <akim@epita.fr>
10662 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
10664 2003-03-29 Akim Demaille <akim@epita.fr>
10666 * doc/bison.texinfo (Strings are Destroyed): New.
10668 2003-03-13 Paul Eggert <eggert@twinsun.com>
10670 * .cvsignore: Add configure.lineno.
10671 * src/.cvsignore: Add yacc.
10672 * tests/.cvsignore: Add testsuite.log.
10673 * doc/fdl.texi: Sync with latest FSF version.
10675 2003-03-12 Paul Eggert <eggert@twinsun.com>
10677 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
10678 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
10679 cursor, instead of leaving it undefined. This fixes a bug
10680 reported by Tim Van Holder in
10681 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
10682 * tests/input.at (Torturing the Scanner): Test the scanner on
10683 an empty input file, which was Tim Van Holder's test case.
10685 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
10686 <sys/resource.h> can be included, include sys/time.h and
10687 sys/times.h first, if available. This works around the SunOS
10688 4.1.4 porting bug reported by Bruce Becker in
10689 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
10691 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
10692 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
10693 AC_HEADER_SYS_WAIT.
10695 Merge changes from gnulib. This was prompted because the CVS
10696 snapshot didn't build on Solaris 7 due to strnlen problems.
10698 These changes need to be merged back into gnulib:
10699 * lib/hash.c: Include <stdbool.h> unconditionally.
10700 * m4/onceonly.m4 (m4_quote): New macro.
10701 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
10702 Quote AC_FOREACH variable-expansions properly.
10703 The 2003-01-03 obstack.h change also needs merging.
10704 {end of changes requiring merging}
10706 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
10707 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
10708 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
10709 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
10710 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
10711 New files, imported from gnulib.
10712 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
10715 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
10716 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
10719 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
10721 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
10722 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.

10725 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
10726 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
10727 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
10728 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
10729 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
10730 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
10731 (jm_PREREQ_ARGMATCH): Remove.
10732 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
10733 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
10735 * src/system.h: Include <stdbool.h> unconditionally.
10737 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
10738 assuming at least C89 in the bitset code for some time now.
10740 2003-03-03 Akim Demaille <akim@epita.fr>
10744 2003-03-02 Akim Demaille <akim@epita.fr>
10746 * doc/bison.texinfo (Table of Symbols): Reactivate the
10747 documentation for %lex-param, and %parse-param.
10749 2003-03-02 Akim Demaille <akim@epita.fr>
10751 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
10752 generate verbose error messages.
10753 Use the number of tokens as an upper bound in yytname, as it
10754 cannot be a non terminal.
10756 2003-03-02 Akim Demaille <akim@epita.fr>
10758 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
10761 2003-03-02 Akim Demaille <akim@epita.fr>
10763 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
10764 Use them to exercise yycheck overrun.
10765 Based on Andrew Suffield's grammar.
10767 2003-03-02 Akim Demaille <akim@epita.fr>
10769 Create tests/local.at for Bison generic testing macros.
10771 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
10772 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):

10775 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
10776 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
10777 * tests/local.at: here.
10778 (AT_COMPILE_CXX): Tags the tests using it as c++.
10779 Ignore the test if CXX is not functional.
10781 2003-03-01 Paul Eggert <eggert@twinsun.com>
10783 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
10784 not loc->end, since loc->end might contain garbage and this leads
10785 to undefined behavior on some platforms.
10786 (id_loc, token_start): Use (IF_LINTed) initial values that do not
10787 depend on *loc, so that the reader doesn't give the the false
10788 impression that *loc is initialized.
10789 (<INITIAL>"%%"): Do not bother setting code_start, since its value
10790 does not survive the return.
10792 2003-03-01 Akim Demaille <akim@epita.fr>
10794 * src/scan-gram.l (code_start): Always initialize it when entering
10795 into yylex, as SC_EPILOGUE is activated *before* the corresponding
10796 yylex invocation. An alternative would be making it static, but
10797 then it starts with the second %%'s beginning, instead of its end.
10799 2003-02-28 Paul Eggert <eggert@twinsun.com>
10801 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
10802 around a UnixWare 7.1.1 porting bug reported by John Hughes in
10803 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
10805 2003-02-26 Paul Eggert <eggert@twinsun.com>
10807 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
10808 Remove Sequent/Pyramid discussion (nobody uses them any more).
10809 Merge VMS and MS-DOS discussion; these ports may well be dead
10810 but let's keep mentioning them for now. Put <> around email
10811 addresses. Add copyright notice.
10813 2003-02-24 Paul Eggert <eggert@twinsun.com>
10815 * data/glr.c (yy_reduce_print): yylineno -> yylno,
10816 to avoid collision with flex use of yylineno.
10817 Problem reported by Bruce Lilly in
10818 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
10819 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
10820 * data/yacc.c (yy_reduce_print): Likewise.
10822 * config/depcomp: Sync with Automake 1.7.3.
10824 2003-02-21 Akim Demaille <akim@epita.fr>
10826 * data/lalr1.cc: Use temporary variables instead of casts to
10827 change integer types.
10828 Suggested by Paul Eggert.
10830 2003-02-21 Akim Demaille <akim@epita.fr>
10832 * doc/bison.texinfo: Use "location" consistently to refer to @n,
10833 to avoid confusions with lalr1.cc's notion of Position.
10834 Suggested by Paul Eggert.
10836 2003-02-20 Akim Demaille <akim@epita.fr>
10838 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
10839 before initial_columns.
10840 (location.hh): Use consistent variable names when defining the
10842 Use "last" so that we subtract from Positions, not from unsigned.
10844 2003-02-20 Akim Demaille <akim@epita.fr>
10846 * data/lalr1.cc (position.hh): New subfile, including the extended
10847 and Doxygen'ed documentation of class Position.
10848 (location.hh): Use it.
10849 Document a` la Doxygen.
10850 With the help of Benoit Perrot.
10852 2003-02-20 Akim Demaille <akim@epita.fr>

10856 Redefine AT_YYERROR_SEES_LOC_IF using it.
10857 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
10859 Don't use the location in yy::Parser::error_ and
10860 yy::Parser::print_ when not %locations.
10861 Activate more lalr1.cc tests.
10863 2003-02-19 Akim Demaille <akim@epita.fr>
10865 * data/lalr1.cc: When displaying a line number, be sure to make it
10868 2003-02-19 Akim Demaille <akim@epita.fr>
10870 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
10872 (YYABORT, YYACCEPT, YYERROR): New.
10873 * tests/calc.at: Renable the lalr1.cc test.
10875 2003-02-19 Akim Demaille <akim@epita.fr>
10877 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
10878 error recovery, mixing with/without pops and discarding of the
10881 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
10883 2003-02-17 Paul Eggert <eggert@twinsun.com>
10885 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
10886 * tests/testsuite.at (AT_COMPILE): Use them.
10887 This fixes the testsuite problem reported by Robert Lentz in
10888 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
10890 2003-02-12 Paul Eggert <eggert@twinsun.com>
10892 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
10893 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in

10895 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
10896 Check for malloc failure, for consistency with yacc.c.
10897 (yytname_size): Remove, for consistency with yacc.c.
10899 The bug still remains in data/lalr1.cc, as I didn't have time
10902 2003-02-06 Akim Demaille <akim@epita.fr>
10904 * configure.ac (GXX): Rename as...
10905 (CXX): this, to keep the original Autoconf semantics.

10924 Adjust the C locations to match those from Emacs: first column is
10926 Change all the expected results.
10927 Conform to the GCS: simplify the locations when applicable.
10928 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
10929 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
10930 these CPP macros with the m4 macros new defined by...

10995 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
10996 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
10997 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
10998 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
10999 param to have same name as that of enum, so that we don't use
11000 "s" to stand for a non-state.
11002 2003-02-02 Akim Demaille <akim@epita.fr>
11004 * src/scan-skel.l: Scan more than one inert character per yylex
11007 2003-02-01 Paul Eggert <eggert@twinsun.com>
11011 * po/LINGUAS: Add ms.
11013 2003-01-30 Akim Demaille <akim@epita.fr>
11015 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
11017 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11019 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
11022 Changes in response to error report by S. Eken: GLR mode does not
11023 handle negative $ indices or $ indices in embedded rules correctly.
11024 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
11026 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
11027 (b4_rhs_location): Ditto.
11028 (yyfill): New function to copy from stack tree into array
11030 (yyuserAction): Modify to allow incremental move of semantic values
11031 to rhs array when in GLR mode.
11032 Define YYFILL to use in user-defined actions to fill semantic array
11034 Remove dummy use of yystack, as there is now a guaranteed use.
11035 (yydoAction): Modify to allow incremental move of semantic values
11036 to rhs array when in GLR mode.
11037 (yyresolveAction): Ditto.
11038 (yyglrShiftDefer): Update comment.
11039 (yyresolveStates): Use X == NULL for pointers, not !X.
11040 (yyglrReduce): Ditto.
11041 (yydoAction): Ditto
11043 * tests/glr-regr1.at: Rename to ...
11044 * tests/glr-regression.at: Add new regression test for the problems
11045 described above (adapted from S. Eken).
11046 Update copyright notice.
11047 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
11048 * tests/Makefile.am: Ditto.
11050 2003-01-28 Paul Eggert <eggert@twinsun.com>
11052 * data/lalr1.cc: Do not use @output_header_name@ unless
11053 b4_defines_flag is set. This fixes two bugs reported by
11055 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
11056 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
11058 2003-01-21 Paul Eggert <eggert@twinsun.com>
11060 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
11061 we don't need to worry about yyerrlab1 being reported as an
11062 "unused label" by non-GCC C compilers. The downside is that if
11063 locations are used then a couple of statements are duplicated each
11064 time YYERROR is invoked, but the upside is that the warnings
11066 (yyerrlab1): Move code to YERROR.
11067 (yyerrlab2): Remove. Change uses back to yyerrlab1.
11068 This reverts some of the 2002-12-27 change.
11070 2003-01-17 Paul Eggert <eggert@twinsun.com>
11072 * src/output.c (symbol_printers_output): Fix typo that led
11073 to core dump. Problem reported by Antonio Rus in
11074 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
11076 2003-01-13 Akim Demaille <akim@epita.fr>,
11077 Quoc Peyrot <chojin@lrde.epita.fr>,
11078 Robert Anisko <anisko_r@lrde.epita.fr>
11080 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
11081 when the stacks contain one element, as the loop would otherwise
11082 free the last state, and then use the top state (the one we just
11083 popped). This means that the initial elements will not be freed
11084 explicitly, as is the case in yacc.c; it is not a problem, as
11085 these elements have fake values.
11087 2003-01-11 Paul Eggert <eggert@twinsun.com>
11089 * NEWS: %expect-violations are now just warnings, reverting
11090 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
11091 bootstrapping problem reported by Matthias Klose; see
11092 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
11093 * src/conflicts.c (conflicts_print): Likewise.
11094 * tests/conflicts.at (%expect not enough, %expect too much,
11095 %expect with reduce conflicts): Likewise.
11096 * doc/bison.texinfo (Expect Decl): Document this. Also mention
11097 that the warning is enabled if the number of conflicts changes
11098 (not necessarily increases).
11100 * src/getargs.c (version): Update copyright year.
11102 2003-01-09 Akim Demaille <akim@epita.fr>
11104 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
11106 2003-01-08 Paul Eggert <eggert@twinsun.com>
11108 * Makefile.maint (WGETFLAGS):
11109 New macro, containing "-C off" to disable proxy caches.
11110 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
11111 (rel-check): Use $(WGET) instead of wget.
11113 2003-01-06 Paul Eggert <eggert@twinsun.com>
11115 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
11116 the GLR paper of Scott, Johnstone and Hussain.
11118 2003-01-04 Paul Eggert <eggert@twinsun.com>
11120 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
11121 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
11122 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
11123 (EXTRA_LIBRARIES): New var, for liby.a.
11124 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
11125 (EXTRA_SCRIPTS): New var, for yacc.
11127 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
11128 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
11129 Problem reported by Nelson H. F. Beebe.
11131 2003-01-03 Paul Eggert <eggert@twinsun.com>
11133 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
11134 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
11135 when compiling Bison 1.875's `bitset bset = obstack_alloc
11136 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
11138 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
11139 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
11140 grow to a huge size with typical invocation.
11142 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
11143 Use the pattern recommended by Autoconf 2.57, except also protect
11144 against double-definition.
11145 * src/system.h: Likewise.
11146 Portability issues reported by Nelson H. F. Beebe.
11148 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
11149 All uses changed. Provide a definition in both C and C++.
11150 (yytrue, yyfalse): Define even if defined (__cplusplus).
11152 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
11153 Reported by Nelson H. F. Beebe.
11155 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
11157 2003-01-02 Paul Eggert <eggert@twinsun.com>
11159 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
11160 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
11161 Bug reported by Nelson H. F. Beebe.
11163 2003-01-01 Paul Eggert <eggert@twinsun.com>
11167 2002-12-30 Paul Eggert <eggert@twinsun.com>
11169 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
11171 (<INITIAL>","): Here. This causes stray "," to be treated
11174 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
11175 last brace in braced code when not in Yacc mode, for compatibility
11176 with Bison 1.35. This resurrects the 2001-12-15 patch to
11179 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
11180 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
11182 2002-12-28 Paul Eggert <eggert@twinsun.com>
11184 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
11185 that of SYM's type. This fixes Debian bug 168069, reported by
11188 2002-12-28 Paul Eggert <eggert@twinsun.com>
11192 Switch back to the Yacc style of conflict reports, undoing some
11193 of the 2002-07-30 change.
11194 * doc/bison.texinfo (Understanding): Use Yacc style for
11195 conflict reports. Also, use new way of locating rules.
11196 * src/conflicts.c (conflict_report):
11197 Renamed from conflict_report_yacc, removing the old
11198 'conflict_report'. Translate the entire conflict report at once,
11199 so that we don't assume that "," has the same interpretation in
11201 (conflicts_output): Use Yacc-style conflict report for each state,
11202 instead of our more-complicated style.
11203 (conflicts_print): Use Yacc-style conflict report, except print
11204 the input file name when not emulating Yacc.
11205 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
11206 Conflicted Reduction, %expect not enough, %expect too much,
11207 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
11208 * tests/existing.at (GNU Cim Grammar): Likewise.
11209 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
11211 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
11212 fatal): Don't invoke fflush; it's not needed and it might even be
11213 harmful for stdout, as stdout might not be open.
11214 * src/reduce.c (reduce_print): Likewise.
11216 2002-12-27 Paul Eggert <eggert@twinsun.com>
11218 Fix a bug where error locations were not being recorded correctly.
11219 This problem was originally reported by Paul Hilfinger in
11220 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
11222 * data/yacc.c (yyparse): New local var yylerrsp, to record the
11223 top of the location stack's error locations.
11224 (yyerrlab): Set it. When discarding a token, push its location
11225 onto yylerrsp so that we don't lose track of the error's end.
11226 (yyerrlab1): Now is only the target of YYERROR, so that we can
11227 properly record the location of the action that failed. For GCC
11228 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
11229 GCC warning about yyerrlab1 being unused if YYERROR is unused.
11230 (yyerrlab2): New label, which yyerrlab now falls through to.
11231 Compute the error's location by applying YYLLOC_DEFAULT to
11232 the locations of all the symbols that went into the error.
11233 * doc/bison.texinfo (Location Default Action): Mention that
11234 YYLLOC_DEFAULT is also invoked for syntax errors.
11235 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
11236 Error locations include the locations of all the tokens that were
11237 discarded, not just the last token.
11239 2002-12-26 Paul Eggert <eggert@twinsun.com>
11241 * src/files.c: Include quote.h.
11242 (compute_output_file_names): Warn if we detect conflicting
11243 outputs to the same file. This should catch the misunderstanding
11244 exemplified by Debian Bug 165349, reported by Bruce Stephens..
11246 * src/conflicts.c (conflicts_print): If the user specifies
11247 "%expect N", report an error if there are any reduce/reduce
11248 conflicts. This is what the manual says should happen.
11249 This fixes Debian bug 130890, reported by Anthony DeRobertis.
11250 * tests/conflicts.at (%expect with reduce conflicts): New test.
11252 Don't use m4_include on relative file names, as it doesn't work as
11253 desired if there happens to be a file with that name under ".".
11255 * m4sugar/version.m4: Remove; it was included but it wasn't used.
11256 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
11257 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
11258 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
11259 * src/output.c (output_skeleton): Use full path names when
11260 specifying a file to include; don't rely on include path, as
11261 it's unreliable when the working file contains a file with
11264 2002-12-25 Paul Eggert <eggert@twinsun.com>
11266 Remove obsolete references to bison.simple and bison.hairy.
11267 Problem mentioned by Aubin Mahe in
11268 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
11269 * data/glr.c: Comment fix.
11270 * doc/bison.1: Remove references. Also, mention "yacc".
11272 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
11275 * src/parse-gram.y (declaration): Use enum "report_states" rather
11276 than its numeric value 1.
11278 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
11279 opening a new one. This fixes Debian bug 165349, reported by
11282 2002-12-24 Paul Eggert <eggert@twinsun.com>
11286 * Makefile.maint (cvs-update): Don't assume that the shell
11287 supports $(...), as Solaris sh doesn't.
11289 * src/parse-gram.y (lloc_default): Remove test for empty
11290 nonterminals at the end, since it didn't change the result.
11292 2002-12-24 Paul Eggert <eggert@twinsun.com>
11294 If the user does not define YYSTYPE as a macro, Bison now declares it
11295 using typedef instead of defining it as a macro. POSIX requires this.
11296 For consistency, YYLTYPE is also declared instead of defined.
11298 %union directives can now have a tag before the `{', e.g., the
11299 directive `%union foo {...}' now generates the C code
11300 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
11301 The default union tag is `YYSTYPE', for compatibility with Solaris 9
11302 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
11303 instead of `yyltype'.
11305 `yystype' and `yyltype' are now obsolescent macros instead of being
11306 typedefs or tags; they are no longer documented and will be
11307 withdrawn in a future release.
11309 * data/glr.c (b4_location_type): Remove.
11310 (YYSTYPE): Renamed from yystype.
11311 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
11312 (struct YYLTYPE): Renamed from struct yyltype.
11313 (YYLTYPE): Renamed from yyltype.
11314 (yyltype, yystype): New (and obsolescent) macros,
11315 for backward compatibility.
11316 * data/yacc.c: Likewise.
11318 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
11319 does not specify a union tag. This is for compatibility with
11322 * src/parse-gram.y (add_param): 2nd arg is now char * not char
11323 const *, since it is now modified by stripping surrounding { }.
11324 (current_braced_code): Remove.
11325 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
11326 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
11327 trailing " {...}". Now of type <chars>.
11328 (grammar_declaration): Adjust to bundled tokens.
11329 (code_content): Remove; stripping is now done by add_param.
11330 (print_token_value): Print contents of bundled tokens.
11331 (token_name): New function.
11333 * src/reader.h (braced_code, current_braced_code): Remove.
11334 (token_name): New decl.
11336 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
11337 token_type, not braced_code code_kind. All uses changed.
11338 (SC_PRE_CODE): New state, for scanning after a keyword that
11339 has (or usually has) an immediately-following braced code.
11340 (token_type): New local var, to keep track of which token type
11341 to return when scanning braced code.
11342 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
11343 <INITIAL>"%parse-param", <INITIAL>"%printer",
11344 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
11345 instead of returning a token type immediately.
11346 (<INITIAL>"{"): Set token type.
11347 (<SC_BRACED_CODE>"}"): Use it.
11348 (handle_action_dollar, handle_action_at): Now returns bool
11349 indicating success. Fail if ! current_rule; this prevents a core dump.
11350 (handle_symbol_code_dollar, handle_symbol_code_at):
11351 Remove; merge body into caller.
11352 (handle_dollar, handle_at): Complain in invalid contexts.
11354 * NEWS, doc/bison.texinfo: Document the above.
11355 * NEWS: Fix years and program names in copyright notice.
11357 2002-12-17 Paul Eggert <eggert@twinsun.com>
11359 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
11360 Reporting, Table of Symbols): Omit mentions of %lex-param and
11361 %parse-param from the documentation for now.
11363 2002-12-15 Paul Eggert <eggert@twinsun.com>
11365 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
11366 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
11367 lookahead symbol, and which sets yychar in parser actions) and it
11368 disagreed with the Bison documentation. Bug
11369 reported by Andrew Walrond.
11371 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
11372 as the caller now does that.
11373 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
11374 (YYEMPTY): Parenthesize right hand side, since others use it.
11375 (yyparse): Don't assume that our generated code is the only code
11378 2002-12-13 Paul Eggert <eggert@twinsun.com>
11382 POSIX requires a "yacc" command.
11383 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
11384 (MOSTLYCLEANFILES): Add yacc.
11386 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
11387 as an alias for bison y.
11389 * po/LINGUAS: Add da.
11391 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
11392 problem with latest <getopt.h>.
11393 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
11395 * doc/fdl.texi: Upgrade to 1.2.
11396 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
11397 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
11398 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
11400 * config/install-sh: Sync with autotools.
11402 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
11403 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
11404 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
11405 locations are requested.
11406 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
11407 locations are requested.
11409 2002-12-12 Paul Eggert <eggert@twinsun.com>
11411 Remove unportable casts and storage allocation tricks.
11412 While we're at it, remove almost all casts, since they
11413 usually aren't needed and are a sign of trouble.
11415 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
11417 * src/derives.c (derives_compute): Do not subtract NTOKENS from
11418 the pointer DSET returned by malloc; this isn't portable.
11419 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
11420 Similarly for DERIVES.
11421 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
11422 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
11423 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
11425 * src/derives.c (derives_compute): Do not bother invoking
11426 int_of_rule_number, since rule numbers are integers.
11428 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
11429 rather than XMALLOC (char, N).
11431 * src/files.c (filename_split): Rewrite to avoid cast.
11433 * src/gram.h (symbol_number_as_item_number,
11434 item_number_as_symbol_number, rule_number_as_item_number,
11435 item_number_as_rule_number):
11436 Now inline functions rather than macros, to avoid casts.
11437 * src/state.h (state_number_as_int): Likewise.
11438 * src/tables.c (state_number_to_vector_number,
11439 symbol_number_to_vector_number): Likewise.
11441 * src/gram.h (int_of_rule_number): Remove; no longer used.
11443 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
11444 since the resulting storage is always stored into.
11446 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
11449 * src/muscle_tab.c (muscle_m4_output):
11450 Now inline. Return bool, not int.
11451 * src/state.c (state_compare): Likewise.

11464 * src/uniqstr.c (uniqstr_print_processor): Likewise.
11465 * src/muscle_tab.c (muscles_m4_output):
11466 Use new functions instead of casting old functions unportably.

11473 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
11474 var instead of casting to long, to avoid casts.
11475 (prepare_states): Use MALLOC rather than alloca, so that we don't
11476 have to worry about alloca.
11477 * src/state.c (state_hash_lookup): Likewise.
11479 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
11480 local var instead of casting to unsigned char, to avoid casts.

11483 STATE_ALLOC): Remove.
11484 (transitions_new, errs_new, reductions_new, state_new): Use malloc

11502 (<inttypes.>, <stdint.h>): Include if available.
11503 (uintptr_t): New type, if system lacks it.
11504 (CALLOC, MALLOC, REALLOC): New macros.
11505 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
11508 * src/tables.c (table_size): Now int, to pacify GCC.

11521 2002-12-09 Paul Eggert <eggert@twinsun.com>
11523 Change identifier spellings to avoid collisions with names
11524 that are reserved by POSIX.
11526 Don't use names ending in _t, since POSIX reserves them.
11527 For consistency, remove _e and _s endings -- they're weren't
11528 needed to remove ambiguity. All uses changed.
11529 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
11530 turn was just renamed from struniq_t.
11531 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
11532 which in turn was just renamed from struniq_processor_t.

11604 value_t_as_yystype -> value_as_yystype.
11606 Don't include <errno.h> in the mainstream code, since it
11607 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
11608 * lib/get-errno.c, lib/get-errno.h: New files.
11609 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

11624 likewise for "STRUNIQ" and "UNIQSTR".
11625 * src/uniqstr.c: Renamed from src/struniq.c.
11626 * src/uniqstr.h: Renamed from src/struniq.h.
11627 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

11650 (ACTION_MAX): Remove; unused.
11651 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
11652 Unnecessary casts removed from above defines.
11655 Fix misspelling in names.
11656 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
11657 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
11661 * lib/timevar.c (timevar_report): Renamed from time_report,
11662 for consistency with other names.

11664 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
11667 Sort include-file uses.
11669 Reorder all include files under src to be in the order "system.h".
11670 then the ../lib include files in angle brackets (alphabetized),
11671 then the . include files in double-quotes (alphabetized). Fix
11672 dependency breakages encountered in this process, as follows:
11673 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
11674 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
11675 * src/state.h: Include "symtab.h".
11677 2002-12-08 Paul Eggert <eggert@twinsun.com>
11679 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
11680 since this causes problems when __file__ contains character
11681 sequences like "@" that are treated specially by src/scan-skel.l.
11682 Instead, just use the file's basename. This fixes the bug
11683 reported by Martin Mokrejs in
11684 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
11686 2002-12-06 Paul Eggert <eggert@twinsun.com>
11688 Add support for rules that do not have trailing semicolons, as
11689 POSIX requires. Improve the quality of locations in Bison
11692 * src/location.c: Include <quotearg.h>.
11693 (empty_location): Now const.
11694 (location_print): New function. Follow the recommendation of the
11695 GNU Coding Standards for locations that span file boundaries.
11696 * src/location.h: Do not include <quotearg.h>; no longer needed.
11697 (boundary): New type.
11698 (location_t): Use it. This allows locations to span file boundaries.
11699 All member uses changed: file -> start.file or end.file (as needed),
11700 first_line -> start.line, first_column -> start.column,
11701 last_line -> end.line, last_column -> end.column.
11702 (equal_boundaries): New function.
11703 (LOCATION_RESET, LOCATION_STEP): Remove.
11704 (LOCATION_PRINT): Remove. All callers changed to use location_print.
11705 (empty_location): Now const.
11706 (location_print): New decl.
11707 * src/parse-gram.y (lloc_default): New function, which handles
11708 empty locations more accurately.
11709 (YYLLOC_DEFAULT): Use it.
11710 (%token COLON): Remove.
11711 (%token ID_COLON): New token.
11713 (declarations, rules): Remove trailing semicolon.
11714 (declaration, rules_or_grammar_declaration):

11717 (rules_or_grammar_declaration): Remove trailing semicolon.
11718 (semi_colon.opt): Remove.
11719 * src/reader.h: Include location.h.
11720 (scanner_cursor): New decl.
11721 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
11723 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
11725 (STEP): Remove. No longer needed, now that adjust_location does
11726 the work. All uses removed.
11727 (scanner_cursor): New var.
11728 (adjust_location): Renamed from extend_location. It now sets
11729 *loc and adjusts the scanner cursor. All uses changed.
11730 Don't bother testing for CR.
11731 (handle_syncline): Remove location arg; now updates scanner cursor.
11732 All callers changed.
11733 (unexpected_end_of_file): Now accepts start boundary of token or
11734 comment, not location. All callers changed. Update scanner cursor,
11736 (SC_AFTER_IDENTIFIER): New state.
11737 (context_state): Renamed from c_context. All uses changed.
11738 (id_loc, code_start, token_start): New local vars.
11739 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
11740 processing of Yacc white space and equivalents here.
11741 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
11742 instead of returning ID immediately, since we need to search for
11743 a subsequent colon.
11744 (<INITIAL>"'", "\""): Save token_start.
11745 (<INITIAL>"%{", "{", "%%"): Save code_start.
11746 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
11747 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
11748 BEGIN context_state at end, not INITIAL.
11749 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
11750 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
11751 Return correct token start.
11752 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
11753 the start of a character, string or multiline comment is found.
11754 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
11755 Reduction): Adjust reported locations to match the more-precise
11756 results now expected.
11757 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
11758 * tests/reduce.at (Useless Rules, Reduced Automaton,
11759 Underivable Rules): Likewise.
11760 * tests/regression.at (Invalid inputs): No longer `expecting ";"
11761 or "|"' now that so many other tokens are allowed by the new grammar.
11763 * src/complain.h (current_file): Remove duplicate decl;
11764 current_file is now owned by files.h.
11765 * src/complain.c, src/scan-gram.l: Include files.h.
11767 2002-12-06 Paul Eggert <eggert@twinsun.com>
11769 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
11770 promotes to int; it might be unsigned int.
11771 * data/yacc.c (yy_reduce_print): Likewise.
11773 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
11774 be #defined in the prologue, not in the Bison declarations.
11775 This fixes Debian Bug 102878, reported by Shaul Karl.
11777 2002-12-02 Paul Eggert <eggert@twinsun.com>
11779 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
11780 * lib/strtoul.c: New file, from gnulib.
11781 This fixes a porting bug reported by Peter Klein in
11782 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
11784 2002-11-30 Paul Eggert <eggert@twinsun.com>
11786 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
11787 and put only a forward declaration in the prologue. This is for
11788 consistency with the other scanner helper functions.
11790 Type clashes now generate warnings, not errors, since it
11791 appears that POSIX may allow some grammars with type clashes.
11792 * src/reader.c (grammar_current_rule_check): Warn about
11793 type clashes instead of complaining.
11794 * tests/input.at (Type Clashes): Expect warnings, not complaints.
11796 Add Yacc library, since POSIX requires it.
11797 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
11798 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
11799 * lib/main.c, lib/yyerror.c: New files.
11801 gram_error can be static; it need not be extern.
11802 * src/reader.h (gram_error): Remove decl.
11803 * src/parse-gram.y (gram_error): Now static. Add static decl.
11804 (print_token_value): Omit parameter names from forward decl,
11807 2002-11-29 Paul Eggert <eggert@twinsun.com>
11809 * doc/bison.texinfo: Emphasize that yylex and yyerror must
11810 be declared before being used. E.g., one should typically
11811 declare them in the prologue. Use GNU coding style in examples.
11812 Put "const" consistently after the type it modifies. Mention
11813 that C99 supports "inline". Mention that yyerror traditionally
11816 %parse-param and %lex-param now take just one argument, the
11817 declaration; the argument name is deduced from the declaration.
11819 * doc/bison.texinfo (Parser Function, Pure Calling, Error
11820 Reporting, Table of Symbols): Document this.
11821 * src/parse-gram.y (add_param): New function.
11823 (declaration): Implement new rule for %parse-param and %lex-param.
11824 * src/scan-gram.l: "," now elicits a warning, rather than being
11825 a token; this is more compatible with byacc.
11826 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
11828 2002-11-27 Paul Eggert <eggert@twinsun.com>
11830 Rename identifiers to avoid real and potential collisions.
11832 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
11833 to avoid collision with lex macro described by Bruce Lilly in
11834 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
11835 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
11836 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
11837 * src/parse-gram.y (print_token_value): Renamed from yyprint.
11839 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
11840 The name "yycontrol" violates the name space rules, and this stuff
11841 wasn't being used anyway.
11842 (input): Remove action; this stuff wasn't being used.
11843 (gram_error): Rename local variable yylloc -> loc.
11844 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
11845 (YY_DECL): Don't use "yy" at start of local variables.
11846 All uses changed, e.g., yylloc -> loc.
11847 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
11848 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
11849 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
11850 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
11852 * src/parse-gram.y (gram_error): loc is now const *.
11853 * src/reader.h (gram_error): Likewise.
11855 2002-11-24 Paul Eggert <eggert@twinsun.com>
11859 * tests/actions.at (Actions after errors): Use an output format
11860 more similar to that of the Printers and Destructors test.
11861 Test the position of the ';' token too.
11862 (Printers and Destructors): Likewise.
11863 (Printers and Destructors: %glr-parser): Remove for now, to avoid
11864 unnecessarily alarming people when the test fails.
11866 * data/yacc.c (yyerrlab1): Move this label down, so that the
11867 parser does not discard the lookahead token if the user code
11868 invokes YYERROR. This change is required for POSIX conformance.
11870 * lib/error.c: Sync with gnulib.
11872 2002-11-22 Paul Eggert <eggert@twinsun.com>
11874 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
11875 * lib/mbswidth.c, lib/mbswidth.h: Likewise.

11882 2002-11-20 Paul Eggert <eggert@twinsun.com>
11884 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
11885 should use `if (! x) abort ();' rather than `assert (x);', and
11886 anyway it's one less thing to worry about configuring.
11888 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
11889 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
11890 and replace all instances of assert with abort.
11891 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.

11920 * src/tables.c (tables_generate): Likewise.
11922 * src/struniq.c (struniq_assert): Now returns void, and aborts
11923 if the assertion is false.
11924 (struniq_assert_p): Remove.
11925 * src/struniq.h: Likewise.
11927 2002-11-18 Paul Eggert <eggert@twinsun.com>
11929 * data/glr.c (yygetLRActions): Replace `yyindex' with
11930 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
11931 This fixes the regression with Sun ONE Studio 7 cc that I reported in
11932 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
11934 2002-11-18 Akim Demaille <akim@epita.fr>
11936 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
11938 From Tim Van Holder.
11940 2002-11-17 Paul Eggert <eggert@twinsun.com>
11942 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
11943 to "SyntaxError" for consistency with my 2002-11-15 change.
11945 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
11946 not define to {}, since this breaks the common use of `YYDPRINTF
11947 ((...));' if a single statement is desired (e.g. before `else').
11948 Work around GCC warnings by surrounding corresponding calls with
11950 (yyhasResolvedValue): Remove unused function.
11951 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
11953 (yyreportSyntaxError): Renamed from yyreportParseError.
11954 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
11956 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
11957 extern when possible. Remove unused initializations.
11959 2002-11-16 Akim Demaille <akim@epita.fr>
11961 Augment the similarity between GLR and LALR traces.
11963 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
11964 (YY_REDUCE_PRINT): New.
11965 (yyparse): Use them.
11966 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
11968 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
11969 state reached after the reduction/recovery, since...
11970 (yyparse, yyprocessOneStack): Report the state we are entering in.
11972 2002-11-16 Akim Demaille <akim@epita.fr>
11974 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
11975 Add support for --trace=skeleton.
11976 * src/scan-skel.l: %option debug.
11977 Scan strings of non-@ or \n instead of character by character.
11978 (scan_skel): Handle trace_skeleton.
11980 (@output_parser_name@, @output_header_name@): ``Restore'' their
11981 support (used to be M4 macros).
11982 * data/yacc.c: Quote larger chunks, a la glr.c.
11983 * data/lalr1.cc: Likewise.
11984 The header guards are no longer available, so use some other
11985 string than `YYLSP_NEEDED'.
11987 2002-11-16 Akim Demaille <akim@epita.fr>
11989 Make the ``Printers and Destructors'' test more verbose, taking
11990 `yacc.c''s behavior as (possibly wrong) reference.
11992 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
11993 instead of fprint on stdout.
11994 Set and report the last_line of the symbols.
11995 Consistently display values and locations.
11997 2002-11-16 Paul Eggert <eggert@twinsun.com>
11999 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
12001 2002-11-15 Paul Eggert <eggert@twinsun.com>
12003 * tests/actions.at (Actions after errors): New test case.
12005 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
12006 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
12007 tests/action.at, tests/calc.at, tests/conflicts.at,
12008 tests/cxx-type.at, tests/regression.at:
12009 "parse error" -> "syntax error" for POSIX compatibility.
12010 "parsing stack overflow..." -> "parser stack overflow" so
12011 that code matches Bison documentation.
12013 2002-11-15 Akim Demaille <akim@epita.fr>
12015 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
12016 take two BRACED_CODE, not two string_content.
12017 Free the scanner's obstack when we are done.
12018 (code_content): New.
12019 * tests/calc.at: Adjust.
12020 * doc/bison.texinfo: Adjust.
12021 Also, make sure to include the `,' for these declarations.
12023 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
12025 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
12026 definition; avoids potential autoreconf problems.
12028 2002-11-15 Akim Demaille <akim@epita.fr>
12030 Always check the value returned by yyparse.
12032 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
12033 returned by yyparse.
12034 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.

12037 returned by yyparse.
12039 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12041 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
12044 2002-11-14 Paul Eggert <eggert@twinsun.com>
12046 * src/output.c (output_skeleton): Call xfopen instead of
12047 duplicating xfopen's body.
12049 Fix bugs reported by Nelson H. F. Beebe in
12050 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
12052 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
12053 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
12054 Group compiler. Instead, use "$CC -E bar.c". Include the .h
12055 file twice in the grammar, as an extra check.
12057 * tests/input.at (Torturing the Scanner): Surround the
12058 backslash-newline tests with "#if 0", to make it less likely that
12059 we'll run into compiler bugs. Bring back solitary \ inside
12060 comment, but add a closing comment to work around HP C bug. Don't
12061 test backslash-newline in C character constant.
12063 2002-11-14 Akim Demaille <akim@epita.fr>
12065 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
12066 status of the compiler.
12067 Calling `exit 1' is no longer needed.
12068 Reported by Nelson H. F. Beebe.
12070 2002-11-14 Akim Demaille <akim@epita.fr>
12072 * tests/atlocal.in (CPPFLAGS): We have config.h.
12073 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
12075 * tests/actions.at, tests/calc.at, tests/conflicts.at,
12076 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
12077 * tests/regression.at, tests/torture.at: Use them for all the
12078 grammars that are to be compiled.
12079 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
12080 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
12081 * doc/bison.texinfo (GLR Parsers): Document `inline'.
12083 2002-11-14 Akim Demaille <akim@epita.fr>
12085 * doc/bison.texinfo: Various formatting changes (alignments in
12086 samples, additional @group/@end group, GCS in samples.
12087 Use @deffn instead of simple @table to define the directives,
12088 macros, variables etc.
12090 2002-11-13 Paul Eggert <eggert@twinsun.com>
12092 Fix some bugs reported by Albert Chin-A-Young in
12093 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
12095 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
12096 -o c"; the HP C compiler chatters during compilation.
12097 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
12098 * tests/headers.at (export YYLTYPE): Likewise.
12100 * tests/input.at (Torturing the Scanner): Remove lines containing
12101 solitary backslashes, as they tickle a bug in the HP C compiler.
12103 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
12104 comments, since they're not portable. Use GNU coding style.
12106 2002-11-13 Akim Demaille <akim@epita.fr>
12108 * data/yacc.c: Leave bigger chunks of quoted text.
12109 (YYDSYMPRINTF): New.
12110 Use it to report symbol activities.
12111 * data/glr.c (YYDSYMPRINTF): New.

12118 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
12119 (yyglrReduce): Return yyok, not 0.
12120 This should avoid the enumerated-type warnings reported
12121 by Nelson H. F. Beebe in
12122 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
12124 * lib/bbitset.h (BITSET_INLINE): Remove.
12125 * lib/bitset.h [! BITSET_INLINE]: Remove.
12126 (bitset_set, bitset_reset, bitset_test): Rename local vars
12127 to avoid shadowing warnings by GCC.
12129 * data/glr.c (inline): Remove #define. It's the user's
12130 responsibility to #define it away, just like 'const'.
12131 This fixes one of the bugs reported by Nelson H. F. Beebe in
12132 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
12134 * Makefile.maint (po-check): Scan .l and .y files instead of the
12135 .c and the .h files that they generate. This fixes the bug
12136 reported by Tim Van Holder in:
12137 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
12138 Look for N_ as well as for _. Try to avoid matching #define for
12140 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
12141 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
12142 * src/scan-gram.l: Revamp regular expressions so that " and '
12143 do not confuse xgettext.
12145 * src/struniq.h (struniq_new): Do not declare the return type
12146 to be 'const'; this violates the C standard.
12147 * src/struniq.c (struniq_new): Likewise.
12149 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
12151 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
12152 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
12155 2002-11-12 Akim Demaille <akim@epita.fr>
12157 * Makefile.maint: Sync with Autoconf:
12158 (local_updates): New.
12160 2002-11-12 Akim Demaille <akim@epita.fr>

12174 2002-11-12 Akim Demaille <akim@epita.fr>
12176 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
12177 Use it to test the GLR parser.
12179 2002-11-12 Akim Demaille <akim@epita.fr>
12181 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
12183 * data/glr.c (yystos): New.
12184 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
12185 (YYDSYMPRINT): New.
12186 (yyval): Don't define it, it is handled via M4.
12187 (yyrecoverParseError): Free verbosely the discarded symbols.
12188 * data/yacc.c (yysymprint): Remove, rather...
12189 (b4_yysymprint_generate): invoke.
12190 * data/c.m4 (b4_yysymprint_generate): New.
12191 Accept pointers as arguments, as opposed to the version from
12193 (b4_yydestruct_generate): Likewise.
12194 * tests/cations.at (Printers and Destructors): Use Bison directives
12195 instead of CPP macros.
12196 Don't rely on internal details.
12198 2002-11-12 Akim Demaille <akim@epita.fr>
12200 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
12201 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
12202 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
12203 it against YYEMPTY and so forth), work on yytoken (i.e., set
12204 it to YYEMPTY etc.).
12205 (yydestruct): Replace with a b4_yydestruct_generate invocation.
12206 (b4_symbol_actions): Remove.
12207 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
12208 for 0, end-of-input.
12210 2002-11-12 Akim Demaille <akim@epita.fr>
12212 * doc/bison.texinfo (Destructor Decl): New.
12214 2002-11-12 Akim Demaille <akim@epita.fr>
12216 * src/tables.c (tables_generate): Use free for pointers that
12217 cannot be NULL, not XFREE.
12218 (pack_vector): Use assert, not fatal, for bound violations.
12219 * src/state.c (state_new): Likewise.
12220 * src/reader.c (reader): Likewise.
12221 * src/lalr.c (set_goto_map): Likewise.
12222 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
12225 2002-11-12 Akim Demaille <akim@epita.fr>
12227 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
12229 * src/scan-gram.l (last_string): Is global to the file, not to
12231 * src/parse-gram.y (input): Don't append the epilogue here,
12232 (epilogue.opt): do it here, and free the scanner's obstack.
12233 * src/reader.c (epilogue_set): Rename as...
12234 (epilogue_augment): this.
12235 * data/c.m4 (b4_epilogue): Defaults to empty.

12293 2002-11-11 Paul Eggert <eggert@twinsun.com>
12295 Revamp to fix many (but not all) of the C- and M4-related quoting
12296 problems. Among other things, this fixes the Bison bug reported
12297 by Jan Hubicka when processing the Bash grammar; see:
12298 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
12300 Use new @ escapes consistently. Represent brackets with @{ and @}
12301 rather than @<:@ and @:>@, since this works a bit better with dumb
12302 editors like vi. Represent @ with @@, since @ is now consistently
12303 an escape. Use @oline@ and @ofile@ rather than __oline__ and
12304 __ofile__, to avoid unexpected expansions. Similarly, use @output
12305 rather than #output.
12307 * data/c.m4 (b4_copyright): Omit file name from comment, since
12308 the file name could contain "*/".
12309 (b4_synclines_flag): Don't quote the 2nd argument; it should already
12310 be quoted. All uses changed.
12312 * data/glr.c: Use new @ escapes consistently.
12313 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
12314 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
12315 Remove, since they couldn't handle arbitrary characters in file
12317 * data/lalr1.cc: Likewise.
12318 * data/yacc.c: Likewise.
12320 * src/files.c (output_infix): Remove; all uses removed.
12321 * src/files.h: Likewise.
12323 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
12324 mishandled funny characters in file names, and anyway it isn't
12326 * data/yacc.c: Likewise.
12327 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
12329 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
12330 * data/yacc.c: Likewise.
12332 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
12334 (muscle_init): Quote filename as a C string.
12335 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
12336 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
12337 * src/output.c (escaped_file_name_output): New function.
12338 (prepare_symbols): Quote tokens for M4.
12339 (prepare): Don't insert output_infix, output_prefix,
12340 output_parser_name, output_header_name; this is now down by scan-skel.
12341 Insert skeleton as a C string.
12343 * src/output.c (user_actions_output, symbol_destructors_output,
12344 symbol_printers_output): Quote filenames for C and M4.
12345 * src/reader.c (prologue_augment, epilogue_set): Likewise.
12347 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
12348 escapes other than \\ and \'; this simplifies the code.
12349 (<SC_STRING>): Likewise, for \\ and \".
12350 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
12351 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
12352 Use new escapes @{ and @} for [ and ].
12354 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
12355 them with auto vars.
12356 Switch to new escape scheme, where @ is the escape character uniformly.
12357 Abort if a stray escape character is found. Avoid unbounded input
12358 buffer when parsing non-escaped text.
12360 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
12361 __oline__, #output, $@, and @{ do not have unintended meanings.
12363 2002-11-09 Paul Eggert <eggert@twinsun.com>
12365 Fix the test failure due to GCC warnings described in
12366 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
12367 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
12368 evaluate to 0 if it's impossible for NINF to be in the respective
12370 (yygetLRActions, yyrecoverParseError): Use them.
12372 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
12373 counted in the token inserted at end of file. Now takes
12374 location_t *, not location_t, so that the location can be
12375 adjusted. All uses changed.
12377 * tests/regression.at (Invalid inputs): Adjust wording in
12378 diagnostic to match the new behavior.
12380 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
12381 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
12382 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
12383 abort ();'. This reduces the runtime of the "Many lookaheads"
12384 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
12387 2002-11-07 Paul Eggert <eggert@twinsun.com>
12389 * src/parse-gram.y (CHARACTER): Remove unused token.
12392 * src/scan-gram.l: Remove stack option. We no longer use the
12393 stack, since the stack was never deeper than 1; instead, use the
12394 new auto var c_context to record the stacked value.
12396 Remove nounput option. At an unexpected end of file, we now unput
12397 the minimal input necessary to end cleanly; this simplifies the
12400 Avoid unbounded token sizes where this is easy.
12402 (unexpected_end_of_file): New function.
12403 Use it to systematize the error message on unexpected EOF.
12404 (last-string): Now auto, not static.

12407 (percent_percent_count): Move decl to just before use.
12408 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
12409 not the (never otherwised-used) CHARACTER.
12411 2002-11-07 Akim Demaille <akim@epita.fr>

12414 yyerror can be variadic.
12416 * data/yacc.c (b4_yyerror_args): New.
12417 Use it when calling yyerror.
12418 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

12424 2002-11-06 Akim Demaille <akim@epita.fr>
12426 #line should have quoted strings.
12427 Ideally, this should be done by m4_quotearg.

12431 * src/output.c (symbol_printers_output)
12432 (symbol_destructors_output): Quote the file name.

12447 * src/output.c (user_actions_output): Likewise.
12448 (prepare): Define 'b4_synclines_flag'.
12449 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
12451 2002-11-06 Akim Demaille <akim@epita.fr>

12461 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12463 * src/tables.c (matching_state): Don't allow states to match if
12464 either has GLR conflict entries.
12466 2002-11-05 Paul Eggert <eggert@twinsun.com>
12468 * src/scan-gram.l: Use more accurate diagnostics, e.g.
12469 "integer out of range" rather than "invalid value".
12470 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
12473 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
12474 Also, remove one static variable in the scanner.
12476 * src/scan-gram.l (braces_level): Now auto, not static.
12477 Initialize to zero if the compiler is being picky.
12478 (INITIAL): Clear braces_level instead of incrementing it.
12479 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
12480 as POSIX 1003.1-2001 requires.
12481 * src/system.h (IF_LINT): New macro, taken from coreutils.
12482 * configure.ac: Define "lint" if --enable-gcc-warnings.
12484 2002-11-05 Akim Demaille <akim@epita.fr>
12486 * src/scan-gram.l: When it starts with `%', complain about the
12487 whole directive, not just that `invalid character: %'.
12489 2002-11-04 Akim Demaille <akim@epita.fr>
12491 * Makefile.maint: Update from Autoconf.
12492 (update, cvs-update, po-update, do-po-update): New.
12494 2002-11-04 Akim Demaille <akim@epita.fr>
12496 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
12498 Have yyerror `use' its arguments.
12499 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
12500 returns true when location & yacc & pure & parse-param.
12501 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
12503 2002-11-04 Akim Demaille <akim@epita.fr>
12505 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
12507 * src/scan-gram.l: Use [\'] instead of ['] to pacify
12510 Use quote, not quote_n since LOCATION_PRINT no longer uses the
12513 2002-11-03 Paul Eggert <eggert@twinsun.com>
12515 * src/reader.c (get_merge_function, grammar_current_rule_check):
12516 Use consistent diagnostics for reporting type name clashes.
12517 Quote the types with <>, for consistency with Yacc.
12518 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
12520 2002-11-03 Akim Demaille <akim@epita.fr>
12522 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
12524 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
12525 (b4_parse_param): Remove.
12526 Use b4_identification.
12527 Propagate b4_pure_args where needed to pass them to yyerror.
12528 * data/glr.m4 (b4_parse_param): Remove.
12529 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)

12532 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
12533 b4_user_formals and b4_user_args.
12534 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
12535 (yyreportAmbiguity): When using a pure parser, also need
12536 the location, and the parse-params.
12538 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
12539 When using a pure parser, also need the parse-params.
12541 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
12542 (%pure-parser + %parse-param) LALR and GLR parsers.
12543 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
12544 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
12545 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
12546 (_AT_DATA_CALC_Y): Equip for purity of yyerror.

12548 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
12549 * doc/bison.texinfo: Untabify the whole file.
12550 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
12551 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
12552 (Error Reporting): Adjust to these new directives.
12553 Document %error-verbose, deprecate YYERROR_VERBOSE.
12555 2002-11-03 Akim Demaille <akim@epita.fr>
12557 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
12558 AT_CHECK_CALC_GLR invocations to use % directives, instead of
12559 command line options.
12560 * tests/cxx-type.at: Formatting changes.
12562 2002-11-03 Paul Eggert <eggert@twinsun.com>
12564 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
12565 to count columns correctly, and to check for invalid inputs.
12567 Use mbsnwidth to count columns correctly. Account for tabs, too.
12568 Include mbswidth.h.
12569 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
12570 (extend_location): New function.
12571 (YY_LINES): Remove.
12573 Handle CRLF in C code rather than in Lex code.

12580 Handle backslash-newline correctly in C code.
12581 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
12582 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
12584 (tag, splice): New EREs. Do not allow NUL or newline in tags.
12585 Use {splice} wherever C allows backslash-newline.
12586 YY_STEP after space, newline, vertical-tab.
12587 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
12589 (letter, id): Don't assume ASCII; e.g., spell out a-z.
12591 ({int}, handle_action_dollar, handle_action_at): Check for integer
12594 (YY_STEP): Omit trailing semicolon, so that it's more like C.
12596 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
12597 as well as \000. Check for UCHAR_MAX, not 255.
12598 Allow \x with an arbitrary positive number of digits, as in C.
12599 Check for overflow here.
12600 Allow \? and UCNs, for compatibility with C.
12602 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
12603 with quote slot used by complain_at.
12605 * tests/input.at: Add tests for backslash-newline, m4 quotes
12606 in symbols, long literals, and funny escapes in strings.
12608 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
12609 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
12610 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.

12612 * m4/mbswidth.m4: New file, from GNU coreutils.
12614 * doc/bison.texinfo (Grammar Outline): Document // comments.
12615 (Symbols): Document that trigraphs have no special meaning in Bison,
12616 nor is backslash-newline allowed.
12617 (Actions): Document that trigraphs have no special meaning.

12622 2002-11-02 Paul Eggert <eggert@twinsun.com>
12624 * src/reader.c: Don't include quote.h; not needed.
12625 (get_merge_function): Reword warning to be consistent with
12626 type clash diagnostic in grammar_current_rule_check.
12628 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
12629 bug in trigraph handling.
12631 * src/output.c (prepare_symbols): When printing token names,
12632 escape "[" as "@<:@" and likewise for "]".
12634 * src/system.h (errno): Remove declaration, as we are now
12635 assuming C89 or better, and C89 guarantees errno.
12637 2002-10-30 Paul Eggert <eggert@twinsun.com>
12639 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
12640 Check for close failures.
12641 * src/files.h (xfclose): Return void, not int, since it always
12643 * src/files.c (xfclose): Likewise. Report I/O error if ferror
12645 * src/output.c (output_skeleton): Use xfclose rather than fclose
12646 and ferror. xfclose now checks ferror.
12648 * data/glr.c (YYLEFTMOST_STATE): Remove.
12649 (yyreportTree): Use a stack-based leftmost state. This avoids
12650 our continuing battles with bogus warnings about initializers.
12652 2002-10-30 Akim Demaille <akim@epita.fr>
12654 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

12667 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
12668 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
12669 we use malloc. Don't assume 'A' through 'Z' are contiguous.
12670 Don't assume strdup exists; POSIX says its an XSI extension.
12671 Check for buffer overflow on input.
12673 2002-10-24 Akim Demaille <akim@epita.fr>
12675 * src/output.c (output_skeleton): Don't disable M4sugar comments
12676 too soon: it results in comments being expanded.
12677 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
12680 2002-10-24 Akim Demaille <akim@epita.fr>
12682 * data/yacc.c (m4_int_type): New.
12683 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
12684 char' as only yacc.c wants K&R portability.
12685 * data/glr.c (yysigned_char): Remove.
12686 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
12687 Reported by Quoc Peyrot.
12689 2002-10-23 Paul Eggert <eggert@twinsun.com>
12691 * src/main.c (main): With --trace=time, report times even if a
12692 non-fatal error occurs. Formerly, the times were reported in some
12693 such cases but not in others.
12694 * src/reader.c (reader): Just return if a complaint has been issued,
12695 instead of exiting, so that 'main' can report times.
12697 2002-10-22 Akim Demaille <akim@epita.fr>
12699 * src/system.h: Include sys/types.
12700 Reported by Bert Deknuydt.
12702 2002-10-23 Paul Eggert <eggert@twinsun.com>
12704 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
12705 Suggested by Art Haas.
12707 2002-10-22 Paul Eggert <eggert@twinsun.com>
12709 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
12710 decl; not needed any more.
12711 * src/main.c (main): Use return to exit, undoing yesterday's change.
12712 The last OS that we could find where this wouldn't work is
12713 SunOS 3.5, and that's too old to worry about now.
12715 * data/glr.c (struct yyltype): Define members even when not
12716 doing locations. This is more consistent with yacc.c, and it
12717 works around the following bug reports:
12718 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
12719 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
12721 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
12722 @acronym consistently. Standardize on "Yacc" instead of "YACC",
12723 "Algol" instead of "ALGOL". Give a bit more history about BNF.
12725 2002-10-22 Akim Demaille <akim@epita.fr>
12727 * data/README: New.
12729 2002-10-21 Paul Eggert <eggert@twinsun.com>
12731 Be consistent about 'bool'; the old code used an enum in one
12732 module and an int in another, and this violates the C standard.
12733 * m4/stdbool.m4: New file, from coreutils 4.5.3.
12734 * configure.ac (AC_HEADER_STDBOOL): Add.
12735 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
12736 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
12737 * src/symtab.c (hash_compare_symbol_t): Likewise.
12738 * src/system.h (bool, false, true): Use a definition consistent
12739 with ../lib/hash.c. All uses changed.
12741 * src/complain.c (warning_issued): Renamed from warn_message_count,
12742 so that we needn't worry about integer overflow (!).
12743 Now of type bool. All uses changed.
12744 (complaint_issued): Renamed from complain_message_count; likewise.
12746 * src/main.c (main): Use exit to exit with failure.
12748 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
12749 rather than 1 and 0.
12750 * src/main.c (main): Likewise.
12751 * src/getargs.c (getargs): Likewise.
12752 * src/reader.c (reader): Likewise.
12754 * src/getarg.c (getargs): Remove duplicate code for
12755 "Try `bison --help'".
12757 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
12758 What was that "2" for?
12760 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
12761 * src/getargs.c (usage): Likewise.
12763 * src/getargs.c (getargs): When there are too few operands, report
12764 the last one. When there are too many, report the first extra
12765 one. This is how diffutils does it.
12767 2002-10-20 Paul Eggert <eggert@twinsun.com>
12769 Remove K&R vestiges.
12770 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
12771 * src/complain.c (VA_START): Remove. Assume prototypes.
12772 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
12773 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
12774 fatal): Assume prototypes.
12775 * src/complain.h: Assume prototypes.
12776 * src/system.h (PARAMS): Remove.
12777 Include <limits.h> unconditionally, since it's guaranteeed even
12778 for a freestanding C89 compiler.
12779 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
12780 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
12782 2002-10-20 Akim Demaille <akim@epita.fr>
12784 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
12785 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.

12788 (yyprocessOneStack): Use them.
12789 (yy_reduce_print): New.
12790 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
12792 2002-10-20 Akim Demaille <akim@epita.fr>
12794 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
12795 arguments and output `void'.
12796 (b4_c_function): Rename as...
12797 (b4_c_function_def): this.
12798 (b4_c_function_decl, b4_c_ansi_function_def)
12799 (b4_c_ansi_function_decl): New.
12800 Change the interpretation of the arguments: before `int, foo', now
12802 * data/yacc.c (yyparse): Prototype and define thanks to these.
12803 Adjust b4_c_function_def uses.
12804 * data/glr.c (yyparse): Likewise, but ANSI only.
12806 2002-10-20 Akim Demaille <akim@epita.fr>
12808 * src/output.c (prepare): Move the definition of `tokens_number',
12809 `nterms_number', `undef_token_number', `user_token_number_max'
12811 (prepare_tokens): Here.

12813 (prepare_symbols): this.
12814 (prepare): Move the definition of `rules_number' to...
12815 (prepare_rules): here.
12816 (prepare): Move the definition of `last', `final_state_number',
12817 `states_number' to...
12818 (prepare_states): here.
12819 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
12821 2002-10-20 Akim Demaille <akim@epita.fr>
12823 * src/tables.h, src/tables.c, src/output.c: Comment changes.
12825 2002-10-20 Akim Demaille <akim@epita.fr>

12841 2002-10-19 Paul Eggert <eggert@twinsun.com>
12843 Do not create a temporary file, as that involves security and
12844 cleanup headaches. Instead, use a pair of pipes.
12845 Derived from a suggestion by Florian Krohm.
12846 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
12847 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
12848 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
12849 (BISON_PREREQ_SUBPIPE): Add.
12850 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
12851 Add subpipe.h, subpipe.c.

12856 (scan_skel): New decl.
12857 (output_skeleton): Use pipe rather than temporary file for m4 input.
12858 Check that m4sugar.m4 is readable, to avoid deadlock.
12859 Check for pipe I/O error.
12860 * src/scan-skel.l (readpipe): Remove decl.
12861 (scan_skel): New function, to be used in place of m4_invoke.
12862 Read from stream rather than file.
12864 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
12865 float, as this generates a warning on Solaris 8 + GCC 3.2 with
12866 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
12867 this generates a more-accurate value anyway.
12869 * lib/timevar.c (timervar_accumulate): Rename locals to
12870 avoid confusion with similarly-named more-global.
12871 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
12873 * src/output.c (prepare): Use xstrdup to convert char const *
12874 to char *, to avoid GCC warning.
12876 2002-10-19 Akim Demaille <akim@epita.fr>
12878 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
12879 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
12880 Use them to have `calc.y' ready for %pure-parser.
12881 * data/yacc.c (YYLEX): Pass a yylex return type to
12882 b4_c_function_call.
12884 2002-10-19 Akim Demaille <akim@epita.fr>
12886 Prototype support of %lex-param and %parse-param.
12888 * src/parse-gram.y: Add the definition of the %lex-param and
12889 %parse-param tokens, plus their rules.
12890 Drop the `_' version of %glr-parser.
12892 * src/scan-gram.l (INITIAL): Scan them.
12893 * src/muscle_tab.c: Comment changes.
12894 (muscle_insert, muscle_find): Rename `pair' as `probe'.
12895 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
12896 (muscle_entry_s): The `value' member is no longer const.
12897 Adjust all dependencies.
12898 * src/muscle_tab.c (muscle_init): Adjust: use
12899 MUSCLE_INSERT_STRING.
12900 Initialize the obstack earlier.
12901 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
12902 (muscle_pair_list_grow): New.
12903 * data/c.m4 (b4_c_function_call, b4_c_args): New.
12904 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
12905 * tests/calc.at: Use %locations, not --locations.
12906 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
12908 2002-10-19 Akim Demaille <akim@epita.fr>
12910 * src/getargs.c (usage): Take status as argument and exit
12912 Report the traditional `Try ... --help' message when status != 0.
12913 (usage, version): Don't take a FILE * as arg, it is pointless.
12914 (getargs): When there is an incorrect number of arguments, make it
12915 an error, and report it GNUlically thanks to `usage ()'.
12917 2002-10-18 Paul Eggert <eggert@twinsun.com>
12919 * data/glr.c (yyreportParseError): Don't assume that sprintf
12920 yields the length of the printed string, as this is not true
12921 on SunOS 4.1.4. Reported by Peter Klein.
12923 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
12924 * tests/conflicts.at (%nonassoc and eof): Likewise.
12925 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
12927 2002-10-17 Akim Demaille <akim@epita.fr>
12929 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
12930 * src/getargs.c (trace_types, trace_args): Adjust.
12931 * src/reader.c (grammar_current_rule_prec_set)
12932 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
12933 Standardize error messages.
12934 And s/@prec/%prec/!
12935 (reader): Use trace_flag to enable scanner/parser debugging,
12936 instead of an adhoc scheme.
12937 * src/scan-gram.l: Remove trailing debugging code.
12939 2002-10-16 Paul Eggert <eggert@twinsun.com>
12941 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
12944 * NEWS: Officially drop support for building Bison with K&R C,
12945 since it didn't work anyway and it's not worth worrying about.
12946 * Makefile.maint (wget_files): Remove ansi2knr.c.
12947 (ansi2knr.c-url_prefix): Remove.
12948 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
12949 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
12950 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
12952 2002-10-15 Paul Eggert <eggert@twinsun.com>
12954 Stop using the "enum_" trick for K&R-style function definitions;
12955 it confused me, and I was the author! Instead, assume that people
12956 who want to use K&R C compilers (when using these modules in GCC,
12957 perhaps?) will run ansi2knr.
12959 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
12960 All uses of "enum_" changed to "enum ".
12961 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
12962 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
12964 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

12971 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
12972 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
12973 Use function prototypes; this removes the need for declaring
12974 static functions simply to provide their prototypes.
12975 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

13041 2002-10-14 Akim Demaille <akim@epita.fr>
13043 * src/tables.c (table_ninf_remap): base -> tab.
13044 Reported by Matt Rosing.
13046 2002-10-14 Paul Eggert <eggert@twinsun.com>
13048 * tests/action.at, tests/calc.at, tests/conflicts.at,
13049 tests/cxx-type.at, tests/headers.at, tests/input.at,
13050 tests/regression.at, tests/synclines.at, tests/torture.at:
13051 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
13052 so that the tests still work even if POSIXLY_CORRECT is set.
13053 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
13055 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
13056 for portability to K&R hosts. Fix typo: signed char is guaranteed
13057 only to 127, not to 128.
13058 * data/glr.c (yysigned_char): New type.
13059 * data/yacc.c (yysigned_char): Likewise.
13060 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
13062 2002-10-13 Paul Eggert <eggert@twinsun.com>
13064 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
13065 true due to limited range of data type" warning from GCC.
13067 * data/c.m4 (b4_token_defines): Protect against double-inclusion
13068 by wrapping enum yytokentype's definition inside #ifndef
13069 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
13071 2002-10-13 Akim Demaille <akim@epita.fr>
13073 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
13074 Un yy- yyrhs to avoid the name clash with the global YYRHS.
13076 2002-10-13 Akim Demaille <akim@epita.fr>
13078 * Makefile.maint: Update from Autoconf 2.54.
13079 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
13081 2002-10-13 Akim Demaille <akim@epita.fr>
13083 * src/print.c (print_state): Separate the list of solved conflicts
13084 from the other items.
13085 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
13087 2002-10-13 Akim Demaille <akim@epita.fr>
13089 Let nondeterministic skeletons be usable with deterministic
13092 With the patch, GAWK compiled by GCC without -O2 passes its test
13093 suite using a GLR parser driven by LALR tables. It fails with -O2
13094 because `struct stat' gives two different answers on my machine:
13095 88 (definition of an auto var) and later 96 (memset on this var).
13096 Hence the stack is badly corrumpted. The headers inclusion is to
13097 blame: if I move the awk.h inclusion before GLR's system header
13098 inclusion, the two struct stat have the same size.
13100 * src/tables.c (pack_table): Always create conflict_table.
13101 (token_actions): Always create conflict_list.
13102 * data/glr.c (YYFLAG): Remove, unused.
13104 2002-10-13 Akim Demaille <akim@epita.fr>
13106 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
13108 (VALGRIND, GXX): New.
13109 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
13110 * tests/bison.in: Run $PREBISON a pre-command.
13111 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
13112 (maintainer-check-g++): New.
13113 * Makefile.am (maintainer-check): New.
13115 2002-10-13 Akim Demaille <akim@epita.fr>
13117 * data/glr.c: Formatting changes.
13118 Tweak some trace messages to match yacc.c's.
13120 2002-10-13 Akim Demaille <akim@epita.fr>
13122 GLR parsers sometimes raise parse errors instead of performing the
13124 Reported by Charles-Henry de Boysson.
13126 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
13127 check the length of the traces when %glr.
13128 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
13130 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
13132 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
13133 (yyltype): Remove the yy prefix from the member names.
13134 (yytable): Complete its comment.
13135 (yygetLRActions): Map error action number from YYTABLE from
13137 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
13138 (which was a bug: it should have been YYTABEL_NINF, and yet it was
13139 not satisfying as we could compare an YYACTION computed from
13140 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
13141 only value for error actions.
13142 (yyreportParseError): In verbose parse error messages, don't issue
13143 `error' in the list of expected tokens.
13144 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
13145 next action to perform to match glr.c's decoding.
13146 (yytable): Complete its comment.
13148 2002-10-13 Paul Eggert <eggert@twinsun.com>
13150 Fix problem reported by Henrik Grubbstroem in
13151 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
13152 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
13153 because the Bison parser reads the second action before reducing
13155 * src/scan-gram.l (rule_length): New static var.
13156 Use it to keep track of the rule length in the scanner, since
13157 we can't expect the parser to be in lock-step sync with the scanner.
13158 (handle_action_dollar, handle_action_at): Use this var.
13159 * tests/actions.at (Exotic Dollars): Test for the problem.
13161 2002-10-12 Paul Eggert <eggert@twinsun.com>
13163 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
13164 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
13165 Include <sys/time.h> when checking for clock_t and struct tms.
13166 Use same include order as source.
13167 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
13168 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
13170 * lib/timevar.c: Update copyright date and clarify comments.
13171 (get_time) [IN_GCC]: Keep the GCC version for reference.
13173 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
13174 GCC version as of today, then merge Bison's changes.
13175 Change "GCC" to "Bison" in copyright notice. timevar.def's
13176 author is Akim, so change that too.
13178 * src/reader.c (grammar_current_rule_check):
13179 Don't worry about the default action if $$ is untyped.
13180 Prevents bogus warnings reported by Jim Gifford in
13181 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
13183 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
13184 * data/glr.c, data/lalr1.cc, data/yacc.c:
13185 Output token definitions before the first part of user declarations.
13186 Fixes compatibility problem reported by Jim Gifford for kbd in
13187 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
13189 2002-10-11 Paul Eggert <eggert@twinsun.com>
13191 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
13192 (yyparse): here. This undoes some of the 2002-07-25 change.
13193 Compatibility problem reported by Ralf S. Engelschall with
13194 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
13196 2002-10-11 Akim Demaille <akim@epita.fr>
13198 * tests/regression.at Characters Escapes): New.

13207 2002-10-10 Paul Eggert <eggert@twinsun.com>
13209 Portability fixes for bitsets; this also avoids several GCC
13212 * lib/abitset.c: Include <stddef.h>, for offsetof.
13213 * lib/lbitset.c: Likewise.
13215 * lib/abitset.c (abitset_bytes): Return a size that is aligned
13216 properly for vectors of objects. Do not assume that adding a
13217 header size to a multiple of a word size yields a value that is
13218 properly aligned for the whole union.
13219 * lib/bitsetv.c (bitsetv_alloc): Likewise.
13221 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
13222 unique names for structures.
13223 * lib/ebitset.c (ebitset_bytes): Likewise.
13224 * lib/lbitset.c (lbitset_bytes): Likewise.
13226 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
13227 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,

13231 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
13232 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
13233 to improve the type-checking that GCC can do.
13234 * lib/bitset.c (bitset_op4_cmp): Likewise.
13235 * lib/bitset_stats.c (bitset_stats_count,
13236 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
13237 bitset_stats_copy, bitset_stats_disjoint_p,

13252 * lib/lbitset.h: Likewise.
13254 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
13255 All instances of parameters of type enum bitset_opts are now of
13256 type enum_bitset_opts, to conform to the C Standard, and similarly
13257 for enum_bitset_type.
13258 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
13259 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
13261 Do not use "struct bitset_struct" to mean different things in
13262 different modules. Not only is this confusing, it violates
13263 the C Standard, which requires that structure types in different
13264 modules must be compatible if one is to be passed to the other.
13265 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
13266 All instances of "struct bitset_struct *" replaced with "bitset".
13267 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
13268 (union bitset_union, struct abitset_struct, struct ebitset_struct,
13269 struct lbitset_struct, struct bitset_stats_struct): New types.
13270 All uses of struct bitset_struct changed to union bitset_union,
13272 * lib/abitset.c (struct abitset_struct, abitset,

13276 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
13277 bitset_struct): Remove.
13278 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
13281 Do not call a function of type T using a call that assumes the
13282 function is of a different type U. Standard C requires that a
13283 function must be called with a type that is compatible with its
13285 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
13287 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
13289 * lib/ebitset.c (PFV): Remove.
13290 * lib/lbitset.c (PFV): Likewise.

13305 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
13306 Use offsetof, for simplicity.
13308 2002-10-06 Paul Eggert <eggert@twinsun.com>
13310 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
13311 the same width as int. This reapplies a hunk of the 2002-08-12 patch
13312 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
13313 which was inadvertently undone by the 2002-09-30 patch.
13314 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
13315 the same width as int.
13317 2002-10-04 Paul Eggert <eggert@twinsun.com>
13321 * configure.ac (AC_INIT), NEWS: Increment version number.
13323 * doc/bison.texinfo: Minor spelling, grammar, and white space
13325 (Symbols): Mention that any negative value returned from yylex
13326 signifies end-of-input. Warn about negative chars. Mention
13327 the portable Standard C character set.
13329 The GNU coding standard says CFLAGS and YFLAGS are reserved
13330 for the installer to set.
13331 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
13332 * src/Makefile.am (AM_CFLAGS): Likewise.
13333 (AM_YFLAGS): Renamed from YFLAGS.
13335 Fix some MAX and MIN problems.

13337 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
13338 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
13339 * src/reader.c (reader): Use it.
13341 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
13342 POSIX 1003.1-2001 has removed fgrep.
13344 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>

13689 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
13690 exit status as failure, not just exit status 1. Sun C exits
13691 with status 2 sometimes.

13861 parsers now contain `reduce 0' as default reduction.

13912 token_translations instead of `0'.
13913 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
13915 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
13916 for the time being: %locations ought to provide it to yyerror.

13920 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

13935 Handle the `- 1' part in rule numbers from/to item numbers.

15566 * tests/regression.at (Web2c Actions): Adjust.
15568 2002-04-22 Akim Demaille <akim@epita.fr>
15570 * src/reader.c (token_translations_init): 256 is now the default
15571 value for the error token, i.e., it will be assigned another
15572 number if the user assigned 256 to one of her tokens.
15573 (reader): Don't force 256 to error.
15574 * doc/bison.texinfo (Symbols): Adjust.
15575 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
15576 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
15577 etc. instead of 10, 20, 30 (which was used to `jump' over error
15578 (256) and undefined (2)).
15580 2002-04-22 Akim Demaille <akim@epita.fr>
15582 Propagate more token_number_t.

15617 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
15618 full stderr, and strip it according to the bison options, instead
15619 of composing the error message from different bits.
15620 This makes it easier to check for several error messages.
15621 Adjust all the invocations.
15622 Add an invocation exercising the error token.
15623 Add an invocation demonstrating a stupid error message.
15624 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

15630 * src/gram.h, src/gram.c (error_token_number): Remove, use
15632 * src/reader.c (reader): Don't specify the user token number (2)

15635 * src/symtab.h: here.
15636 (state_t.number): Is a token_number_t.
15637 * src/print.c, src/reader.c: Use undeftoken->number instead of

15642 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
15643 `user_token_number_max'.
15644 Output `undef_token_number'.

15665 * src/gram.h (item_number_t): New, the type of item numbers in
15666 RITEM. Note that it must be able to code symbol numbers as
15667 positive number, and the negation of rule numbers as negative

15684 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
15685 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
15686 passes, but produces negative #line number, once fixed, GCC is
15687 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of

15887 2002-04-07 Akim Demaille <akim@epita.fr>
15889 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
15890 lacking `+ 1' to nrules, Bison reported as useless a token if it
15891 was used solely to set the precedence of the last rule...
15893 2002-04-07 Akim Demaille <akim@epita.fr>
15895 * data/bison.c++, data/bison.simple: Don't output the current file
15896 name in #line, to avoid useless diffs between two identical
15897 outputs under different names.
15899 2002-04-07 Akim Demaille <akim@epita.fr>
15901 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

15916 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
15917 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
15918 RHS, instead of being an index in RITEMS.
15920 2002-04-04 Paul Eggert <eggert@twinsun.com>
15922 * doc/bison.texinfo: Update copyright date.
15923 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

16149 notice in each output file.
16151 2002-02-28 Akim Demaille <akim@epita.fr>
16153 * data/bison.c++: Copy the prologue of bison.simple to fetch
16154 useful M4 definitions, such as b4_header_guard.
16156 2002-02-25 Akim Demaille <akim@epita.fr>
16158 * src/getargs.c (version): Give the name of the authors, and use a

16187 2002-02-14 Paul Eggert <eggert@twinsun.com>
16189 Remove the support for C++ namespace cleanliness; it was
16190 causing more problems than it was curing, since it didn't work
16191 properly on some nonstandard C++ compilers. This can wait
16192 for a proper C++ parser.
16194 * NEWS: Document this.
16195 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
16196 of C++, as it's treated like C now.

16210 2002-02-13 Andreas Schwab <schwab@suse.de>
16212 * src/output.c (output_rule_data): Don't output NULL, it might
16213 not be defined yet.
16215 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
16217 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
16218 (Copyright notice): Update.

16232 * tests/input.at: New.
16234 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16236 * data/bison.c++: Replace some direct m4 expansions by constants. Be
16237 more consistent when naming methods and variables. Put preprocessor
16238 directives around tables only needed for debugging.
16240 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16242 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
16244 (yy::b4_name::parse): Use print_.
16246 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16248 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
16250 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16252 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
16254 (yy::b4_name::parse): Build verbose error messages, and use error_.
16256 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
16258 * data/bison.c++: Fix m4 quoting in comments.
16260 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
16262 * data/bison.c++: Adjust the parser code. Fix some muscles that were
16263 not expanded by m4.
16265 2002-02-05 Akim Demaille <akim@epita.fr>
16267 * data/bison.c++: Adjust to the M4 back end.
16268 More is certainly needed.
16270 2002-02-05 Akim Demaille <akim@epita.fr>
16272 Give a try to M4 as a back end.
16274 * lib/readpipe.c: New, from wdiff.
16275 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
16277 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
16278 specific values. Now it is m4 that performs the lookup.
16279 * src/parse-skel.y: Remove.
16280 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
16281 * src/output.c (actions_output, guards_output)
16282 (token_definitions_output): No longer keeps track of the output
16283 line number, hence remove the second argument.
16284 (guards_output): Check against the guard member of a rule, not the
16287 (output_skeleton): Don't look for the skeleton location, let m4 do
16289 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
16291 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
16292 (prepare): Given that for the time being changesyntax is not
16293 usable in M4, rename the muscles using `-' to `_'.
16294 Define `defines_flag', `output_parser_name' and `output_header_name'.
16295 * src/output.h (actions_output, guards_output)
16296 (token_definitions_output): Adjust prototypes.
16297 * src/scan-skel.l: Instead of scanning the skeletons, it now
16298 processes the output of m4: `__oline__' and `#output'.
16299 * data/bison.simple: Adjust to be used by M4(sugar).
16300 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
16302 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
16303 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
16304 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
16305 shamelessly stolen from CVS Autoconf.
16307 2002-02-05 Akim Demaille <akim@epita.fr>
16309 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
16310 * configure.in: Check for the declarations of free and malloc.
16311 * src/muscle_tab.c: Adjust.
16313 2002-02-05 Akim Demaille <akim@epita.fr>
16315 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
16316 which have no values.
16318 2002-02-05 Akim Demaille <akim@epita.fr>
16320 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
16323 2002-01-29 Paul Eggert <eggert@twinsun.com>
16325 * src/bison.simple (YYSIZE_T): Do not define merely because
16326 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
16327 On some platforms, <alloca.h> does not declare YYSTD (size_t).
16329 2002-01-27 Akim Demaille <akim@epita.fr>
16331 Fix `%nonassoc and eof'.
16333 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
16334 which were not properly copied! Replace
16335 memcpy (res->errs, src->errs, src->nerrs);
16337 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
16339 * tests/regression.at (%nonassoc and eof): Adjust to newest
16340 Autotest: `.' is not in the PATH.
16342 2002-01-27 Akim Demaille <akim@epita.fr>
16344 * tests/sets.at (AT_EXTRACT_SETS): New.
16345 (Nullable): Use it.
16348 2002-01-26 Akim Demaille <akim@epita.fr>
16350 * tests/actions.at, tests/calc.at, tests/headers.at,
16351 * tests/torture.at: Adjust to the newest Autotest which no longer
16352 forces `.' in the PATH.
16354 2002-01-25 Akim Demaille <akim@epita.fr>
16356 * tests/regression.at (%nonassoc and eof): New.
16357 Suggested by Robert Anisko.
16359 2002-01-24 Akim Demaille <akim@epita.fr>
16361 Bison dumps core when trying to complain about broken input files.
16362 Reported by Cris van Pelt.
16364 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
16365 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
16367 (Invalid inputs): Strengthen: exercise parse_percent_token.
16369 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
16371 * src/Makefile.am: Add bison.c++.
16372 * src/bison.c++: New skeleton.
16374 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
16378 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
16380 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
16382 2002-01-20 Marc Autret <marc@gnu.org>
16384 * src/files.c (compute_output_file_names): Fix
16386 2002-01-20 Marc Autret <marc@gnu.org>
16388 * tests/output.at: New test.
16389 * src/files.c (compute_base_names): Don't map extensions when
16390 the YACC flag is set, use defaults.
16391 Reported by Evgeny Stambulchik.
16393 2002-01-20 Marc Autret <marc@gnu.org>
16395 * src/system.h: Need to define __attribute__ away for non-GCC
16396 compilers as well (i.e., the vendor C compiler).
16397 Suggested by Albert Chin-A-Young.
16399 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
16401 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
16402 canonical definition.
16403 * src/system.h: Use the canonical definition for PARAMS (avoids
16404 a conflict with the macro from lib/hash.h).
16406 2002-01-11 Akim Demaille <akim@epita.fr>
16408 * configure.in: Use AC_FUNC_STRNLEN.
16409 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
16411 2002-01-09 Akim Demaille <akim@epita.fr>
16413 * src/files.c, src/files.h (output_infix): New.
16414 (tab_extension): Remove.
16415 (compute_base_names): Compute the former, drop the latter.
16416 * src/output.c (prepare): Insert the muscles `output-infix', and
16418 * src/parse-skel.y (string, string.1): New.
16419 (section.header): Use it.
16420 (section.yacc): Remove.
16421 (prefix): Remove too.
16422 * src/scan-skel.l: Adjust.
16423 * src/bison.simple, src/bison.hairy: Adjust.
16425 2002-01-09 Akim Demaille <akim@epita.fr>
16427 * configure.in (WERROR_CFLAGS): Compute it.
16428 * src/Makefile.am (CFLAGS): Pass it.
16429 * tests/atlocal.in (CFLAGS): Idem.
16430 * src/files.c: Fix a few warnings.
16431 (get_extension_index): Remove, unused.
16433 2002-01-08 Akim Demaille <akim@epita.fr>
16435 * src/getargs.c (AS_FILE_NAME): New.
16436 (getargs): Use it to convert DOSish file names.
16437 * src/files.c (base_name): Rename as full_base_name to avoid
16438 clashes with `base_name ()'.
16439 (filename_split): New.
16440 (compute_base_names): N-th rewrite, using filename_split.
16442 2002-01-08 Akim Demaille <akim@epita.fr>
16444 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
16445 New, stolen from the Fileutils 4.1.
16446 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
16447 * configure.in: Check for the presence of memrchr, and of its
16450 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
16452 * lib/hash.h (__P): Added definition for this macro.
16453 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
16454 BUILT_SOURCES, to ensure they are generated first.
16455 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
16456 %error-verbose to allow bootstrapping with bison 1.30x.
16458 2002-01-06 Akim Demaille <akim@epita.fr>
16460 * src/reader.c (parse_braces): Don't fetch the next char, the
16461 convention is to fetch on entry.
16462 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
16463 'switch' without a following semicolon.
16464 * tests/regression.at (braces parsing): New.
16466 2002-01-06 Akim Demaille <akim@epita.fr>
16468 Bison is dead wrong in its RR conflict reports.
16470 * tests/torture.at (GNU Cim Grammar): New.
16471 * src/conflicts.c (count_rr_conflicts): Fix.
16473 2002-01-06 Akim Demaille <akim@epita.fr>
16475 Creating package.m4 from configure.ac causes too many problems.
16477 * tests/Makefile.am (package.m4): Create it by hand,
16478 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
16480 2002-01-06 Akim Demaille <akim@epita.fr>
16482 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
16485 2002-01-04 Paul Eggert <eggert@twinsun.com>
16487 * doc/bison.texinfo (Debugging):
16488 Remove YYSTDERR; it's no longer defined or used.
16489 Also, s/cstdio.h/cstdio/.
16491 2002-01-03 Akim Demaille <akim@epita.fr>
16493 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
16495 2002-01-03 Akim Demaille <akim@epita.fr>
16497 * src/parse-skel.y (process_skeleton): Don't bind the parser's
16498 tracing code to --trace, wait for a better --trace option, with
16501 2002-01-03 Akim Demaille <akim@epita.fr>
16503 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
16504 The ISO C++ standard is extremely clear about it: stderr is
16505 considered a macro, not a regular symbol (see table 94 `Header
16506 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
16507 Therefore std:: does not apply to it. It still does with fprintf.
16508 Also, s/cstdio.h/cstdio/.
16510 2002-01-03 Akim Demaille <akim@epita.fr>
16512 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
16513 for non system headers.
16515 2002-01-02 Akim Demaille <akim@epita.fr>
16517 Equip the skeleton chain with location tracking, runtime trace,
16518 pure parser and scanner.
16520 * src/parse-skel.y: Request a pure parser, locations, and prefix
16522 (%union): Having several members with the same type does not help
16523 type mismatches, simplify.
16524 (YYPRINT, yyprint): New.
16525 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
16526 (skel_error): this.
16528 * src/scan-skel.l: Adjust to these changes.
16529 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
16530 (LOCATION_PRINT, skel_control_t): New.
16532 2001-12-30 Akim Demaille <akim@epita.fr>
16534 * src/parse-skel.y: Get rid of the shift/reduce conflict:
16535 replace `gb' with BLANKS.
16536 * src/scan-skel.l: Adjust.
16538 2001-12-30 Akim Demaille <akim@epita.fr>
16540 * src/system.h: We don't need nor want bcopy.
16541 Throw away MS-DOS crap: we don't need getpid.
16542 * configure.in: We don't need strndup. It was even causing
16543 problems: because Flex includes the headers *before* us,
16544 _GNU_SOURCE is not defined by config.h, and therefore strndup was
16546 * lib/xstrndup.c: New.
16547 * src/scan-skel.l: Use it.
16548 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
16549 * src/parse-skel.y: Use %directives instead of #defines.
16551 2001-12-30 Akim Demaille <akim@epita.fr>
16553 * src/skeleton.h: New.
16554 * src/output.c (output_parser, output_master_parser): Remove, dead
16556 * src/output.h (get_lines_number, actions_output, guards_output)
16557 (token_definitions_output): Prototype them.
16558 * src/parse-skel.y: Add the license notice.
16559 Include output.h and skeleton.h.
16560 (process_skeleton): Returns void, and takes a single parameter.
16561 * src/scan-skel.l: Add the license notice.
16562 Include skeleton.h.
16563 Don't use %option yylineno: it seems that then Flex imagines
16564 REJECT has been used, and therefore it won't reallocate its
16565 buffers (which makes no other sense to me than a bug). It results
16566 in warnings for `unused: yy_flex_realloc'.
16568 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
16570 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)

16573 (MUSCLE_INSERT_PREFIX): Move from here...
16575 * src/bison.hairy: Add a section directive. Put braces around muscle
16576 names. This parser skeleton is still broken, but Bison should not
16577 choke on a bad muscle 'syntax'.

16581 * src/files.h (strsuffix, stringappend): Add declarations.
16582 (tab_extension): Add declaration.
16583 (short_base_name): Add declaration.
16585 * src/files.c (strsuffix, stringappend): No longer static. These
16586 functions are used in the skeleton parser.
16587 (tab_extension): New.
16588 (compute_base_names): Use the computations done in this function
16589 to guess if the generated parsers should have '.tab' in their
16591 (short_base_name): No longer static.
16593 * src/output.c (output_skeleton): New.
16594 (output): Disable call to output_master_parser, and give a try to
16595 a new skeleton handling system.

16597 (token_definitions_output, get_lines_number): No longer static.
16599 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
16601 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
16604 * src/parse-skel.y: New file.
16605 * src/scan-skel.l: New file.
16607 2001-12-29 Akim Demaille <akim@epita.fr>
16609 %name-prefix is broken.
16611 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
16612 Adjust all dependencies.
16613 * tests/headers.at (export YYLTYPE): Strengthen this test: use
16616 Renaming yylval but not yylloc is not consistent. Now we do.
16618 * src/bison.simple: Prefix yylloc if used.
16619 * doc/bison.texinfo (Decl Summary): Document that.
16621 2001-12-29 Akim Demaille <akim@epita.fr>
16623 * doc/bison.texinfo: Promote `%long-directive' over
16625 Remove all references to fixed-output-files, yacc is enough.
16627 2001-12-29 Akim Demaille <akim@epita.fr>
16629 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
16630 user prologue. These are defaults.
16631 * tests/actions.at (Mid-rule actions): Make sure the user can
16632 define YYDEBUG and YYERROR_VERBOSE.
16634 2001-12-29 Akim Demaille <akim@epita.fr>
16636 * src/output.c (header_output): Don't forget to export YYLTYPE and
16638 * tests/headers.at (export YYLTYPE): New, make sure it does.
16639 * tests/regression.at (%union and --defines, Invalid CPP headers):
16641 * tests/headers.at: here.
16643 2001-12-29 Akim Demaille <akim@epita.fr>
16645 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
16647 2001-12-29 Akim Demaille <akim@epita.fr>
16649 * tests/actions.at (Mid-rule actions): Output on a single line
16650 instead of several.
16652 2001-12-29 Akim Demaille <akim@epita.fr>
16654 * doc/bison.texinfo: Formatting changes.
16656 2001-12-29 Akim Demaille <akim@epita.fr>
16658 Don't store the token defs in a muscle, just be ready to output it
16659 on command. Now possible via `symbols'. Fixes a memory leak.
16661 * src/output.c (token_definitions_output): New.
16662 (output_parser, header_output): Use it.
16663 * src/reader.c (symbols_save): Remove.
16665 2001-12-29 Akim Demaille <akim@epita.fr>
16667 * src/bison.simple: Do not provide a default for YYSTYPE and
16668 YYLTYPE before the user's prologue. Otherwise it's hardly... a
16671 2001-12-29 Akim Demaille <akim@epita.fr>
16673 Mid-rule actions are simply... ignored!
16675 * src/reader.c (readgram): Be sure to attach mid-rule actions to
16676 the empty-rule associated to the dummy symbol, not to the host
16678 * tests/actions.at (Mid-rule actions): New.
16680 2001-12-29 Akim Demaille <akim@epita.fr>
16684 * src/reader.c (reader): Free grammar.
16686 2001-12-29 Akim Demaille <akim@epita.fr>
16690 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
16691 since it allocates it for each state, although only one is needed.
16692 (allocate_storage): Do it here.
16694 2001-12-29 Akim Demaille <akim@epita.fr>
16696 * src/options.h, src/options.c (create_long_option_table): Rename
16698 (long_option_table_new): this, with a clearer prototype.
16699 (percent_table): Remove, unused,
16700 * src/getargs.c (getargs): Adjust.
16702 2001-12-29 Akim Demaille <akim@epita.fr>
16704 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c

16708 2001-12-29 Akim Demaille <akim@epita.fr>
16710 * src/lalr.c (build_relations): Rename `states' as `states1'.
16711 Sorry, I don't understand exactly what it is, no better name...
16713 2001-12-29 Akim Demaille <akim@epita.fr>
16715 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
16716 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

16732 * src/gram.c, src/gram.h (sprec, sassoc): Remove.

16738 Adjust all users to use symbols[i]->tag.
16740 2001-12-29 Akim Demaille <akim@epita.fr>
16742 * src/gram.h, src/gram.c (symbols): New, similar to state_table
16744 * src/reader.c (packsymbols): Fill this table.
16746 * src/conflicts.c (resolve_sr_conflict): Adjust.
16747 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
16749 Use symbols[i]->tag instead of tags[i].
16751 2001-12-29 Akim Demaille <akim@epita.fr>
16753 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
16754 In addition, put a comment in there, to replace...
16755 * tests/regression.at (%union and C comments): Remove.
16757 2001-12-29 Akim Demaille <akim@epita.fr>
16759 * tests/regression.at (Web2c Actions): Blindly move the actual
16760 output as expected output. The contents *seem* right to me, but I
16761 can't pretend reading perfectly parser tables... Nonetheless, all
16762 the other tests pass correctly, the table look OK, even though the
16763 presence of `$axiom' is to be noted: AFAICS it is useless (but
16766 2001-12-29 Akim Demaille <akim@epita.fr>
16768 * src/reader.c (readgram): Don't add the rule 0 if there were no
16769 rules read. In other words, add it _after_ having performed
16770 grammar sanity checks.
16771 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
16773 2001-12-29 Akim Demaille <akim@epita.fr>
16775 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
16776 visible, and some states have now a different number.
16778 2001-12-29 Akim Demaille <akim@epita.fr>
16780 * src/reader.c (readgram): Bind the initial rule's lineno to that
16782 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
16783 (Solved SR Conflicts): Adjust rule 0's line number.
16785 2001-12-29 Akim Demaille <akim@epita.fr>
16787 Fix the `GAWK Grammar' failure.
16789 * src/LR0.c (final_state): Initialize to -1 so that we do compute
16790 the reductions of the first state which was mistakenly confused
16791 with the final state because precisely final_state was initialized
16793 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
16794 now noticed by Bison.
16795 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
16796 have a reduction on $default.
16798 2001-12-29 Akim Demaille <akim@epita.fr>
16800 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
16802 * src/closure.c (print_closure): Likewise.
16803 * src/derives.c (print_derives): Likewise.
16804 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
16807 2001-12-29 Akim Demaille <akim@epita.fr>
16809 * src/lalr.c (lookaheads_print): New.
16810 (lalr): Call it when --trace-flag.
16811 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
16814 2001-12-29 Akim Demaille <akim@epita.fr>
16816 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
16817 when walking through ritem, even via rule->rhs.
16818 * src/reduce.c (dump_grammar, useful_production, reduce_output)
16819 (useful_production, useless_nonterminals): Likewise.
16820 (reduce_grammar_tables): Likewise, plus update nritems.
16821 * src/nullable.c (set_nullable): Likewise.
16822 * src/lalr.c (build_relations): Likewise.
16823 * tests/sets.at (Nullable): Adjust.
16824 Fortunately, now, the $axiom is no longer nullable.
16826 2001-12-29 Akim Demaille <akim@epita.fr>
16828 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

16836 2001-12-29 Akim Demaille <akim@epita.fr>
16838 * src/output.c: Comment changes.
16840 2001-12-27 Paul Eggert <eggert@twinsun.com>
16842 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
16843 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
16844 Sparc, as they were causing more porting problems than the
16845 (minor) performance improvement was worth.
16847 Also, catch up with 1.31's YYSTD.
16849 2001-12-27 Akim Demaille <akim@epita.fr>
16851 * src/output.c (output_gram): Rely on nritems, not the
16852 0-sentinel. See below.
16853 Use -1 as separator, not 0.
16854 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
16855 Rely on -1 as separator in yyrhs, instead of 0.
16856 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
16857 twice `Now at end of input', therefore there are two lines less to
16860 2001-12-27 Akim Demaille <akim@epita.fr>
16862 * tests/regression.at (Unresolved SR Conflicts):
16863 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
16866 2001-12-27 Akim Demaille <akim@epita.fr>
16868 * src/LR0.c (new_state): Recognize the final state by the fact it
16869 is reached by eoftoken.
16870 (insert_start_shifting_state, insert_eof_shifting_state)
16871 (insert_accepting_state, augment_automaton): Remove, since now
16872 these states are automatically computed from the initial state.
16873 (generate_states): Adjust.
16874 * src/print.c: When reporting a rule number to the user, substract
16875 1, so that the axiom rule is rule 0, and the first user rule is 1.
16876 * src/reduce.c: Likewise.
16877 * src/print_graph.c (print_core): For the time being, just as for
16878 the report, depend upon --trace-flags to dump the full set of
16880 * src/reader.c (readgram): Once the grammar read, insert the rule
16881 0: `$axiom: START-SYMBOL $'.
16882 * tests/set.at: Adjust: rule 0 is now displayed, and since the
16883 number of the states has changed (the final state is no longer
16884 necessarily the last), catch up.
16886 2001-12-27 Akim Demaille <akim@epita.fr>
16888 Try to make the use of the eoftoken valid. Given that its value
16889 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
16890 is used instead of > 0 where appropriate, (ii), depend upon nritems
16891 instead of the 0-sentinel.
16893 * src/gram.h, src/gram.c (nritems): New.
16894 Expected to be duplication of nitems, but for the time being...
16895 * src/reader.c (packgram): Assert nritems and nitems are equal.
16896 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
16897 * src/closure.c (print_closure, print_fderives): Likewise.

16904 * src/main.c (main): If there are complains after grammar
16905 reductions, then output the report anyway if requested, then die.
16906 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
16907 * src/reader.c (eoftoken): New.
16908 (parse_token_decl): If the token being defined has value `0', it
16910 (packsymbols): No longer hack `tags' to insert `$' by hand.
16911 Be sure to preserve the value of the eoftoken.
16912 (reader): Make sure eoftoken is defined.
16913 Initialize nsyms to 0: now eoftoken is created just like the others.
16914 * src/print.c (print_grammar): Don't special case the eof token.
16915 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
16916 lie anyway, albeit pleasant.
16917 * tests/calc.at: Exercise error messages with eoftoken.
16918 Change the grammar so that empty input is invalid.
16919 Adjust expectations.
16920 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
16922 2001-12-27 Akim Demaille <akim@epita.fr>
16924 * configure.in: Check the protos of strchr ans strspn.
16925 Replace strchr if needed.
16926 * src/system.h: Provide the protos of strchr, strspn and memchr if
16928 * lib/strchr.c: New.
16929 * src/reader.c (symbols_save): Use strchr.

16933 * src/print.c, src/print_graph.c (escape): New.
16934 Use it to quote the TAGS outputs.
16935 * src/print_graph.c (print_state): Now errors are in red, and
16936 reductions in green.
16937 Prefer high to wide: output the state number on a line of its own.
16939 2001-12-27 Akim Demaille <akim@epita.fr>
16941 * src/state.h, src/state.c (reductions_new): New.

16995 * src/output.c (output): Adjust.
16996 * src/reader.c (parse_braces): New, factoring...
16997 (copy_action, copy_guard): these two which are renamed as...
16998 (parse_action, parse_guard): these.
16999 As a voluntary consequence, using braces around guards is now
17002 2001-12-27 Akim Demaille <akim@epita.fr>
17004 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
17005 * src/reader.c (symbol_list): `guard' and `guard_line' are new
17007 (symbol_list_new): Adjust.
17008 (copy_action): action_line is the first line, not the last.
17009 (copy_guard): Just as for actions, store the `action' only, not
17010 the switch/case/break flesh.
17011 Don't parse the user action that might follow the guard, let...
17012 (readgram): do it, i.e., now, there can be an action after a
17014 In other words the guard is just explicitly optional.
17015 (packgram): Adjust.
17016 * src/output.c (guards_output): New.
17017 (output_parser): Call it when needed.
17018 (output): Also free the guard and attrs obstacks.
17019 * src/files.c, src/files.h (obstack_save): Remove.
17020 (output_files): Remove.
17021 As a result, if one needs the former `.act' file, using an
17022 appropriate skeleton which requires actions and guards is now
17024 * src/main.c (main): Adjust.
17025 * tests/semantic.at: New.
17026 * tests/regression.at: Use `input.y' as input file name.

17035 2001-12-27 Akim Demaille <akim@epita.fr>
17037 All the hacks using a final pseudo state are now useless.
17039 * src/LR0.c (set_state_table): state_table holds exactly nstates.
17040 * src/lalr.c (nLA): New.
17041 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
17042 instead of lookaheadsp from the pseudo state (nstate + 1).
17044 2001-12-27 Akim Demaille <akim@epita.fr>
17046 * src/output.c (action_row, token_actions): Use a state_t instead
17047 of a integer, and nlookaheads instead of the following state's

17054 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
17055 (conflicts_print, print_reductions): Use a state_t instead of an
17056 integer when referring to a state.
17057 As much as possible, depend upon nlookaheads, instead of the
17058 `lookaheadsp' member of the following state (since lookaheads of
17059 successive states are successive, the difference between state n + 1
17060 and n served as the number of lookaheads for state n).
17061 * src/lalr.c (add_lookback_edge): Likewise.
17062 * src/print.c (print_core, print_actions, print_state)
17063 (print_results): Likewise.
17064 * src/print_graph.c (print_core, print_actions, print_state)
17065 (print_graph): Likewise.
17066 * src/conflicts.h: Adjust.
17068 2001-12-27 Akim Demaille <akim@epita.fr>
17070 * src/bison.hairy: Formatting/comment changes.
17072 Remove `register' indications.
17073 Add plenty of `static'.
17075 2001-12-27 Akim Demaille <akim@epita.fr>
17077 * src/output.c (prepare): Drop the muscle `ntbase' which
17078 duplicates ntokens.
17079 * src/bison.simple: Formatting/comment changes.
17080 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
17081 is an undocumented synonym.
17083 2001-12-22 Akim Demaille <akim@epita.fr>
17085 * src/output.c (output_table_data): Change the prototype to use
17086 `int' for array ranges: some invocations do pass an int, not a
17088 Reported by Wayne Green.
17090 2001-12-22 Akim Demaille <akim@epita.fr>
17092 Some actions of web2c.y are improperly triggered.
17093 Reported by Mike Castle.
17095 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
17096 * tests/regression.at (Web2c): Rename as...
17097 (Web2c Report): this.
17098 (Web2c Actions): New.
17100 2001-12-22 Akim Demaille <akim@epita.fr>
17102 Reductions in web2c.y are improperly reported.
17103 Reported by Mike Castle.
17105 * src/conflicts.c (print_reductions): Fix.
17106 * tests/regression.at (Web2c): New.
17108 2001-12-18 Akim Demaille <akim@epita.fr>
17110 Some host fail on `assert (!"foo")', which expands to
17111 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
17112 Reported by Nelson Beebee.
17114 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
17115 `#define it_succeeded 0' and `assert (it_succeeded)'.
17117 2001-12-17 Marc Autret <autret_m@epita.fr>
17119 * src/bison.simple: Don't hard code the skeleton line and filename.
17120 * src/output.c (output_parser): Rename 'line' as 'output_line'.
17121 New line counter 'skeleton_line' (skeleton-line muscle).
17123 2001-12-17 Paul Eggert <eggert@twinsun.com>
17125 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
17126 YYDEBUG must be defined to a nonzero value.
17128 * src/bison.simple (yytname): Do not assume that the user defines
17129 YYDEBUG to a properly parenthesized expression.
17131 2001-12-17 Akim Demaille <akim@epita.fr>
17133 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
17134 nlookaheads is a new member.
17136 * src/lalr.h (nlookaheads): Remove this orphan declaration.
17137 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
17140 2001-12-17 Akim Demaille <akim@epita.fr>
17142 * src/files.h, src/files.c (open_files, close_files): Remove.
17143 * src/main.c (main): Don't open/close files, nor invoke lex_free,
17145 * src/reader.c (reader): Do it.
17147 2001-12-17 Akim Demaille <akim@epita.fr>
17149 * src/conflicts.c (print_reductions): Formatting changes.
17151 2001-12-17 Akim Demaille <akim@epita.fr>
17153 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
17154 (flush_reduce): New.
17155 (resolve_sr_conflict): Adjust.
17157 2001-12-17 Akim Demaille <akim@epita.fr>
17159 * src/output.c (output_obstack): Be static and rename as...
17160 (format_obstack): this, to avoid any confusion with files.c's
17162 * src/reader.h (muscle_obstack): Move to...
17163 * src/output.h: here, since it's defined in output.c.
17165 2001-12-17 Akim Demaille <akim@epita.fr>
17167 * src/output.c (action_row, save_column, default_goto)
17168 (sort_actions, matching_state, pack_vector): Better variable
17171 2001-12-17 Akim Demaille <akim@epita.fr>
17173 * src/output.c: Various formatting changes.
17175 2001-12-17 Akim Demaille <akim@epita.fr>
17177 * src/files.c (output_files): Free the output_obstack.
17178 * src/main.c (main): Call print and print_graph conditionally.
17179 * src/print.c (print): Work unconditionally.
17180 * src/print_graph.c (print_graph): Work unconditionally.
17181 * src/conflicts.c (log_resolution): Output only if verbose_flag.
17183 2001-12-16 Marc Autret <autret_m@epita.fr>
17185 * src/output.c (actions_output): Fix. When we use %no-lines,
17186 there is one less line per action.
17188 2001-12-16 Marc Autret <autret_m@epita.fr>
17190 * src/bison.simple: Remove a useless #line directive.
17191 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
17192 * src/output.c (get_lines_number): New.
17193 (output_parser): Adjust, now takes care about the lines of a
17195 Fix line numbering.
17196 (actions_output): Computes the number of lines taken by actions.
17197 (output_master_parser): Insert new skeleton which is the name of
17198 the output parser file name.
17200 2001-12-15 Marc Autret <autret_m@epita.fr>
17202 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
17204 2001-12-15 Marc Autret <autret_m@epita.fr>
17206 * src/output.c (output_gram): Keep track of the hairy one.
17208 2001-12-15 Akim Demaille <akim@epita.fr>
17210 Make `make distcheck' work.
17212 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
17213 system.h which uses libgettext.h.
17215 2001-12-15 Akim Demaille <akim@epita.fr>
17217 * src/nullable.c (set_nullable): Useless rules must be skipped,
17218 otherwise, since we range over their symbols, we might look at a
17219 nonterminal which no longer ``exists'', i.e., it is not counted in
17220 `nvars', hence we overflow our arrays.
17222 2001-12-15 Akim Demaille <akim@epita.fr>
17224 The header can also be produced directly, without any obstack!
17227 * src/files.c, src/files.h (defines_obstack): Remove.
17228 (compute_header_macro): Global.
17229 (defines_obstack_save): Remove.
17230 * src/reader.c (parse_union_decl): No longer output to
17231 defines_obstack: its content can be found in the `stype' muscle
17233 (output_token_translations): Merge into...
17234 (symbols_output): this.
17236 (symbols_save): this.
17238 * src/output.c (header_output): New.
17241 2001-12-15 Akim Demaille <akim@epita.fr>
17243 * src/reader.c (parse_union_decl): Instead of handling two obstack
17244 simultaneously, use one to define the `stype' muscle, and use the
17245 value of the latter to fill defines_obstack.
17246 (copy_comment): Remove.
17247 (copy_comment2): Work for a single obstack.
17249 (copy_comment): this.
17251 2001-12-15 Akim Demaille <akim@epita.fr>
17253 * src/lex.c, src/lex.h (xgetc): No longer static.
17254 * src/reader.c (parse_union_decl): Revamp.
17256 2001-12-15 Akim Demaille <akim@epita.fr>
17258 Still making progress in separating Bison into (i) input, (ii)
17259 process, (iii) output: now we can directly output the parser file
17260 without using table_obstack at all.
17262 * src/files.c, src/files.h (table_obstack): Bye bye.
17263 (parser_file_name): New.
17264 * src/files.c (compute_output_file_names): Compute it.
17265 * src/output.c (actions_output, output_parser)
17266 (output_master_parser): To a file instead of an obstack.
17268 2001-12-15 Akim Demaille <akim@epita.fr>
17270 Attach actions to rules, instead of pre-outputting them to
17273 * src/gram.h (rule_t): action and action_line are new members.
17274 * src/reader.c (symbol_list): Likewise.
17275 (copy_action): Save the actions within the rule.
17276 (packgram): Save them in rule_table.
17277 * src/output.c (actions_output): New.
17278 (output_parser): Use it on `%%actions'.
17279 (output_rule_data): Don't free rule_table.
17281 (prepare): Don't save the `action' muscle.
17282 * src/bison.simple: s/%%action/%%actions/.
17284 2001-12-15 Akim Demaille <akim@epita.fr>
17286 * src/reader.c (copy_action): When --yacc, don't append a `;'
17287 to the user action: let it fail if lacking.
17288 Suggested by Arnold Robbins and Tom Tromey.
17290 2001-12-14 Akim Demaille <akim@epita.fr>
17292 * src/lex.c (literalchar): Simply return the char you decoded, non
17293 longer mess around with obstacks and int pointers.
17294 Adjust all callers.
17296 2001-12-14 Akim Demaille <akim@epita.fr>
17298 * src/lex.c (literalchar): Don't escape the special characters,
17299 just decode them, and keep them as char (before, eol was output as
17300 the 2 char string `\n' etc.).
17301 * src/output.c (output_rule_data): Use quotearg to output the
17304 2001-12-13 Paul Eggert <eggert@twinsun.com>
17306 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
17307 Do not infringe on the global user namespace when using C++.
17308 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
17309 All uses of `fprintf' and `stderr' changed.
17311 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
17313 2001-12-13 Akim Demaille <akim@epita.fr>
17315 The computation of nullable is broken: it doesn't handle empty
17318 * tests/torture.at (GNU AWK Grammar): New.
17319 * tests/sets.at (Nullable): New.
17320 * src/nullable.c (set_nullable): Instead of blindly looping over
17321 `ritems', loop over the rules, and then over their rhs's.
17323 Work around Autotest bugs.
17325 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
17326 frame, because Autotest understand lines starting with a `+' as
17327 traces from the shell. Then, they are not processed properly.
17328 Admittedly an Autotest bug, but we don't have time to wait for
17329 Autotest to catch up.
17330 * tests/regression.at (Broken Closure): Adjust to the new table
17333 * tests/sets.at: here.
17335 2001-12-13 Akim Demaille <akim@epita.fr>
17337 * src/closure.c (closure): Use nrules instead of playing tricks
17338 with BITS_PER_WORD.
17340 2001-12-13 Akim Demaille <akim@epita.fr>
17342 * src/print.c (print_actions): Output the handling of `$' as the
17343 traces do: shifting the token EOF. Before EOF was treated as a
17345 * tests/regression.at: Adjust some tests.
17346 * src/print_graph.c (print_core): Complete the set of items via
17347 closure. The next-to-final and final states are still unsatisfying,
17348 but that's to be addressed elsewhere.
17349 No longer output the rule numbers, but do output the state number.
17350 A single loop for the shifts + gotos is enough, but picked a
17351 distinct color for each.
17352 (print_graph): Initialize and finalize closure.
17354 2001-12-13 Akim Demaille <akim@epita.fr>
17356 * src/reader.c (readgram): Remove dead code, an strip useless
17358 (get_type): Remove, unused.
17360 2001-12-12 Akim Demaille <akim@epita.fr>
17362 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
17363 on that of lib/error.c.
17365 2001-12-12 Akim Demaille <akim@epita.fr>
17367 Some hosts don't like `/' in includes.
17369 * src/system.h: Include libgettext.h without qualifying the path.
17370 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
17373 2001-12-11 Marc Autret <autret_m@epita.fr>
17375 * src/output.c (output_parser): Remove useless muscle.
17377 2001-12-11 Marc Autret <autret_m@epita.fr>
17379 * src/bison.simple: Remove #line just before %%epilogue. It
17380 is now handled in ...
17381 * src/reader.c (read_additionnal_code): Add the output of a
17382 #line for the epilogue.
17384 2001-12-10 Marc Autret <autret_m@epita.fr>
17386 * src/reader.c (copy_definition): Re-use CPP-outed code which
17387 replace precedent remove.
17388 * src/bison.simple: Remove #line before %%prologue because
17389 %%input-line is wrong at this time.
17391 2001-12-10 Marc Autret <autret_m@epita.fr>
17393 * src/reader.c (symbols_output): Clean up.
17394 * src/output.c (output_gram, output): Clean up.
17396 2001-12-10 Akim Demaille <akim@epita.fr>
17398 * src/lalr.c (initialize_lookaheads): New. Extracted from...
17399 * src/LR0.c (set_state_table): here.
17400 * src/lalr.c (lalr): Call it.
17402 2001-12-10 Akim Demaille <akim@epita.fr>
17404 * src/state.h (shifts): Remove the `number' member: shifts are
17405 attached to state, hence no longer need to be labelled with a
17408 2001-12-10 Akim Demaille <akim@epita.fr>
17410 Now that states have a complete set of members, the linked list of
17411 shifts is useless: just fill directly the state's shifts member.
17413 * src/state.h (shifts): Remove the `next' member.
17414 * src/LR0.c (first_state, last_state): Remove.
17415 Adjust the callers.
17416 (augment_automaton): Don't look for the shifts that must be added
17417 a shift on EOF: it is those of the state we looked for! But now,
17418 since shifts are attached, it is no longer needed to looking
17419 merely by its id: its number.
17421 2001-12-10 Akim Demaille <akim@epita.fr>
17423 * src/LR0.c (augment_automaton): Better variable locality.
17424 Remove an impossible branch: if there is a state corresponding to
17425 the start symbol being shifted, then there is shift for the start
17426 symbol from the initial state.
17428 2001-12-10 Akim Demaille <akim@epita.fr>
17430 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
17431 only when appropriate: when insert_start_shifting_state' is not
17433 * tests/regression.at (Rule Line Numbers): Adjust.
17435 2001-12-10 Akim Demaille <akim@epita.fr>
17437 * src/LR0.c (augment_automaton): Now that all states have shifts,
17438 merge the two cases addition shifts to the initial state.
17440 2001-12-10 Akim Demaille <akim@epita.fr>
17442 * src/lalr.c (set_state_table): Move to...
17444 * src/lalr.c (lalr): Don't call it...
17445 * src/LR0.c (generate_states): do it.
17446 * src/LR0.h (first_state): Remove, only the table is used.
17448 2001-12-10 Akim Demaille <akim@epita.fr>
17450 * src/LR0.h (first_shift, first_reduction): Remove.
17451 * src/lalr.c: Don't use first_shift: find shifts through the
17454 2001-12-10 Akim Demaille <akim@epita.fr>
17456 * src/LR0.c: Attach shifts to states as soon as they are
17458 * src/lalr.c (set_state_table): Instead of assigning shifts to
17459 state, just assert that the mapping was properly done.
17461 2001-12-10 Akim Demaille <akim@epita.fr>
17463 * src/LR0.c (insert_start_shift): Rename as...
17464 (insert_start_shifting_state): this.
17465 (insert_eof_shifting_state, insert_accepting_state): New.
17466 (augment_automaton): Adjust.
17467 Better locality of the variables.
17468 When looking if the start_symbol is shifted from the initial
17469 state, using `while (... symbol != start_symbol ...)' sounds
17470 better than `while (... symbol < start_symbol ...)': If fail
17471 to see how the order between symbols could be relevant!
17473 2001-12-10 Akim Demaille <akim@epita.fr>
17475 * src/getargs.h: Don't declare `spec_name_prefix' and
17476 `spec_file_prefix', declared by src/files.h.
17477 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
17478 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
17479 * src/output.c (prepare): Adjust.
17480 * src/reader.c (symbols_output): Likewise.
17481 * src/vmsgetargs.c: Vaguely adjust, but who cares?
17483 2001-12-10 Akim Demaille <akim@epita.fr>
17485 * src/muscle_tab.c (muscle_init): NULL is a better default than
17488 2001-12-10 Akim Demaille <akim@epita.fr>
17490 * src/reader.c (reader): Calling symbols_output once is enough.
17492 2001-12-10 Akim Demaille <akim@epita.fr>
17494 Now that states have a complete set of members, the linked list of
17495 reductions is useless: just fill directly the state's reductions
17498 * src/state.h (struct reductions): Remove member `number' and
17500 * src/LR0.c (first_reduction, last_reduction): Remove.
17501 (save_reductions): Don't link the new reductions, store them in
17503 * src/lalr.c (set_state_table): No need to attach reductions to
17504 states, it's already done.
17505 * src/output.c (output_actions): No longer free the shifts, then
17506 the reductions, then the states: free all the states and their
17509 2001-12-10 Akim Demaille <akim@epita.fr>
17511 * src/options.c (OPTN, DRTV, BOTH): New.
17512 (option_table): Use them.
17514 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
17515 the job of system.h.
17516 * src/options.c: Don't include stdio.h and xalloc.h for the same
17519 2001-12-10 Akim Demaille <akim@epita.fr>
17521 * src/output.c (output, prepare): Make sure the values of the
17522 muscles `action' and `prologue' are 0-terminated.
17524 2001-12-10 Akim Demaille <akim@epita.fr>
17526 Clean up GCC warnings.
17528 * src/reader.c (copy_action): `buf' is not used.
17529 (parse_skel_decl): Be static.
17530 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
17531 * src/options.h (create_long_option_table): Have a real prototype.
17532 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
17533 (hash_delete_at): Return const void *.
17534 Adjust casts to preserve the const.
17536 2001-12-10 Akim Demaille <akim@epita.fr>
17538 * configure.in: Require 2.52g.
17539 M4 is not needed, but AUTOM4TE is.
17540 * m4/m4.m4: Remove.
17541 * tests/Makefile.am: Adjust.
17543 2001-12-10 Akim Demaille <akim@epita.fr>
17545 One structure for states is enough, even though theoretically
17546 there are LR(0) states and LALR(1) states.
17548 * src/lalr.h (state_t): Remove.
17549 (state_table): Be state_t **, not state_t *.
17550 * src/state.h (core, CORE_ALLOC): Rename as...
17551 (state_t, STATE_ALLOC): this.
17552 Add the LALR(1) members: shifts, reductions, errs.
17553 * src/LR0.c (state_table): Rename as...
17554 (state_hash): this, to avoid name clashes with the global
17556 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
17557 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
17559 2001-12-10 Akim Demaille <akim@epita.fr>
17561 Bison dumps core on bash.y.
17562 Reported by Pascal Bart.
17564 * src/warshall.c (bitmatrix_print): New.
17566 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
17567 j must be the outer loop.
17568 * tests/regression.at (Broken Closure): New.
17570 2001-12-05 Akim Demaille <akim@epita.fr>
17572 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
17574 Reported by Peter Hamorsky.
17576 2001-12-05 Akim Demaille <akim@epita.fr>
17578 * src/conflicts.c (err_table): Remove.
17579 (resolve_sr_conflict): Adjust.
17580 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
17582 (state_t.reductions, state_t.shifts): this.
17584 2001-12-05 Akim Demaille <akim@epita.fr>
17586 * src/reduce.c (reduce_grammar_tables): No longer disable the
17587 removal of useless rules via CPP but via `if (0)', so that the
17588 compiler still check the code is valid.
17589 For instance, it should have noticed `rline' no longer exists: use
17590 the `line' member of rule_t.
17591 * src/gram.c (dummy, rline): Remove, unused.
17593 2001-12-05 Akim Demaille <akim@epita.fr>
17595 * src/output.c (pack_vector): Use assert, not berror.
17596 * src/main.c (berror): Remove, unused.
17598 2001-12-05 Akim Demaille <akim@epita.fr>
17600 New experimental feature: if --verbose --trace output all the
17601 items of a state, not only its kernel.
17603 * src/print.c (print_core): If `trace_flag', then invoke closure
17604 before outputting the items of the state (print_core is no longer
17605 a correct name them).
17606 (print_results): Invoke new_closure/free_closure if needed.
17608 2001-12-05 Akim Demaille <akim@epita.fr>
17610 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
17611 * src/closure.c, src/closure.h (itemsetsize): Rename as...
17612 (nitemset): for consistency with the rest of the project.

17616 * src/closure.c (print_closure): Improve.
17617 (closure): Use it for printing input and output.
17619 2001-12-05 Akim Demaille <akim@epita.fr>
17621 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
17622 indexed by nonterminals.
17624 2001-12-05 Akim Demaille <akim@epita.fr>
17626 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
17628 * src/warshall.h: Remove accidental duplication of the content.
17630 2001-12-05 Akim Demaille <akim@epita.fr>

17642 2001-12-05 Akim Demaille <akim@epita.fr>
17644 * src/output.c (action_row): De-obfuscate
17645 using the good o' techniques: arrays not pointers, variable
17646 locality, BITISSET, RESETBIT etc.
17648 2001-12-05 Akim Demaille <akim@epita.fr>
17650 Pessimize the code to simplify it: from now on, all the states
17651 have a valid SHIFTS, which NSHIFTS is possibly 0.
17653 * src/LR0.c (shifts_new): Be global and move to..
17654 * src/state.c, src/state.h: here.
17655 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
17656 * src/print_graph: Adjust.
17658 2001-12-05 Akim Demaille <akim@epita.fr>
17660 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
17661 * src/conflicts.c: Use it.
17662 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
17663 incorrectly ``simplified''.
17665 2001-12-05 Akim Demaille <akim@epita.fr>
17667 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
17668 using the good o' techniques: arrays not pointers, variable
17669 locality, BITISSET, RESETBIT etc.
17671 2001-12-05 Akim Demaille <akim@epita.fr>
17673 * src/state.h (SHIFT_SYMBOL): New.
17674 * src/conflicts.c: Use it to deobfuscate.
17676 2001-12-05 Akim Demaille <akim@epita.fr>
17678 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
17679 (print_reductions): De-obfuscate using the good o' techniques:

17703 2001-12-05 Akim Demaille <akim@epita.fr>
17705 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
17706 * src/lalr.c: Use them.
17708 2001-12-05 Akim Demaille <akim@epita.fr>
17710 * src/LR0.c (augment_automaton): Formatting changes.
17711 Better variable locality.

17715 * src/lalr.c (matrix_print): New.
17716 (transpose): Use it.

17719 2001-12-05 Akim Demaille <akim@epita.fr>
17721 * src/lalr.c (maxrhs): Move to...
17722 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
17723 * src/lalr.c (build_relations): Adjust.
17725 2001-12-05 Akim Demaille <akim@epita.fr>
17727 * src/lalr.c (transpose): Free the memory allocated to the
17728 argument, as it is replaced by the results by the unique caller.
17729 (build_relations): Merely invoke transpose: it handles the memory
17731 Improve variable locality.
17732 Avoid variables used as mere abbreviations.
17733 (compute_lookaheads): Use arrays instead of pointers.
17735 2001-12-05 Akim Demaille <akim@epita.fr>
17737 * src/lalr.c (initialize_F): Improve variable locality.
17738 Avoid variables used as mere abbreviations.
17740 2001-12-05 Akim Demaille <akim@epita.fr>
17742 * src/derives.c (print_derives): Display the ruleno.
17743 * src/lalr.c (initialize_F, transpose): Better variable locality

17751 2001-12-05 Akim Demaille <akim@epita.fr>
17753 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
17754 the handling of squeue.
17755 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17757 2001-12-05 Akim Demaille <akim@epita.fr>
17759 Because useless nonterminals are now kept alive (instead of being
17760 `destroyed'), we now sometimes examine them, and store information
17761 related to them. Hence we need to know their number, and adjust
17762 memory allocations.
17764 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
17766 * src/LR0.c (allocate_itemsets): The memory allocated to
17767 `symbol_count' was used for two different purpose: once to count
17768 the number of occurrences of each symbol, and later reassigned to
17769 `shift_symbol', containing the symbol that can be shifted from a
17771 Deobfuscate, i.e., allocate, use and free `symbol_count' here
17773 (new_itemsets): Allocate `shift_symbol' here.
17774 (allocate_itemsets): symbol_count includes useless nonterminals.
17775 Make room for them.
17776 (free_storage): Use `free', not `XFREE', for pointers that cannot
17779 2001-12-05 Akim Demaille <akim@epita.fr>
17781 * src/nullable.c (set_nullable): Deobfuscate the handling of
17783 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17785 2001-12-05 Akim Demaille <akim@epita.fr>
17787 * src/gram.c, src/gram.h (ritem_print): New.
17788 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
17789 (This useless function was defined only to work around VMS linkers
17790 that can't handle compilation units with variables only).
17791 * src/reduce.c (dump_grammar): Use it to trace the construction of
17794 2001-12-04 Paul Eggert <eggert@twinsun.com>
17796 * src/bison.simple (union yyalloc): Change member names
17797 to be the same as the stack names.
17798 (yyparse): yyptr is now union yyalloc *, not char *.
17799 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
17800 and may generate better code on some machines.
17801 (yystpcpy): Use prototype if __STDC__ is defined, not just
17802 if __cplusplus is defined.
17804 2001-11-30 Akim Demaille <akim@epita.fr>
17806 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
17807 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
17808 Gettext doesn't compile cleanly, and dies with -Werror.
17809 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
17810 Include WARNING_CFLAGS here.
17811 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
17812 before being defined.
17814 2001-11-27 Paul Eggert <eggert@twinsun.com>
17816 * lib/quotearg.h (quotearg_n, quotearg_n_style):
17817 First arg is int, not unsigned.
17818 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
17819 (SIZE_MAX, UINT_MAX): New macros.
17820 (quotearg_n_options): Abort if N is negative.
17821 Avoid overflow check on hosts where size_t is 64 bits and int
17822 is 32 bits, as overflow is impossible there.
17823 Fix off-by-one typo that caused unnecessary reallocation.
17825 2001-11-29 Paul Eggert <eggert@twinsun.com>
17827 Name space cleanup in generated parser.
17829 * doc/bison.texinfo (Bison Parser): Discuss system headers
17830 and their effect on the user name space.
17832 * src/bison.simple:
17833 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
17834 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
17835 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
17837 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
17838 on user names when possible.
17840 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
17841 Simplify test for whather <alloca.h> exists.
17843 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
17845 (<stdio.h>): Include if YYDEBUG.
17847 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
17848 ! defined (yyoverflow) && ! defined (yymemcpy).
17850 (yymemcpy, yyparse): Rename local variables as needed so that
17851 they all begin with 'yy'.
17853 (yystrlen, yystpcpy): New functions.
17855 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
17858 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
17859 instead of relying on string.h functions. Use YYSTACK_ALLOC
17860 and YYSTACK_FREE instead of malloc and free.
17862 2001-11-30 Akim Demaille <akim@epita.fr>
17864 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
17865 before their first uses.

17872 2001-11-30 Akim Demaille <akim@epita.fr>
17874 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
17875 if body instead of `;' to pacify GCC's warnings.
17877 2001-11-30 Akim Demaille <akim@epita.fr>
17879 Instead of mapping the LHS of unused rules to -1, keep the LHS
17880 valid, but flag the rules as invalid.
17882 * src/gram.h (rule_t): `useful' is a new member.
17883 * src/print.c (print_grammar): Adjust.
17884 * src/derives.c (set_derives): Likewise.
17885 * src/reader.c (packgram, reduce_output): Likewise.
17886 * src/reduce.c (reduce_grammar_tables): Likewise.
17887 * tests/reduce.at (Underivable Rules, Useless Rules): New.
17889 2001-11-30 Akim Demaille <akim@epita.fr>

17896 2001-11-30 Akim Demaille <akim@epita.fr>
17898 * src/reduce.c (nonterminals_reduce): Instead of throwing away
17899 useless nonterminals, move them at the end of the symbol arrays.
17900 (reduce_output): Adjust.
17901 * tests/reduce.at (Useless Nonterminals): Adjust.
17903 2001-11-30 Akim Demaille <akim@epita.fr>

17913 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
17914 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
17916 (union yyalloc): New type.
17917 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
17918 an arbitrary restriction on hosts where size_t is wider than int.
17920 (yyparse): Don't dump core if alloca or malloc fails; instead, report
17921 a parser stack overflow. Allocate just one block of memory for all
17922 three stacks, instead of allocating three blocks; this typically is
17923 faster and reduces fragmentation.
17925 Do not limit the number of items in the stack to a value that fits
17926 in 'int', as this is an arbitrary limit on hosts with 64-bit
17927 size_t and 32-bit int.
17929 2001-11-29 Marc Autret <autret_m@epita.fr>
17931 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
17932 of defining YYERROR_VERBOSE.

17977 2001-11-28 Akim Demaille <akim@epita.fr>
17979 * src/closure.c (closure): `b' and `ruleno' denote the same value:
17982 2001-11-28 Akim Demaille <akim@epita.fr>
17984 * src/closure.c (closure): Instead of looping over word in array
17985 then bits in words, loop over bits in array.
17987 2001-11-28 Akim Demaille <akim@epita.fr>
17989 * src/closure.c (closure): No longer optimize the special case
17990 where all the bits of `ruleset[r]' are set to 0, to make the code
17993 2001-11-28 Akim Demaille <akim@epita.fr>
17995 * src/closure.c (closure): `r' and `c' are new variables, used to
17996 de-obfuscate accesses to RULESET and CORE.
17998 2001-11-28 Akim Demaille <akim@epita.fr>
18000 * src/reduce.c (reduce_print): Use ngettext.

18010 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,

18012 From Enrico Scholz.
18014 2001-11-27 Paul Eggert <eggert@twinsun.com>
18016 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
18017 use alloca when we didn't want to, and vice versa.

18359 use abs. path to find config.h.
18360 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

19739 New, from fileutils 4.0.37.
19740 * configure.in: Require Autoconf 2.49c. I took some time before
19741 making this decision. This is the only way out for portability
19742 issues in Bison, it would mean way too much duplicate effort to
19743 import in Bison features implemented in 2.49c since 2.13.

19791 introduces a guaranteed SEGV for semantic parsers.

20155 The location tracking mechanism is precious for parse error
20156 messages. Nevertheless, it is enabled only when `@n' is used in
20157 the grammar, which is a different issue (you can use it in error
20158 message, but not in the grammar per se). Therefore, there should
20159 be another means to enable it.
20161 * src/getargs.c (getargs): Support `--locations'.
20162 (usage): Report it.
20163 * src/getargs.h (locationsflag): Export it.
20164 * src/lex.c (percent_table): Support `%locations'.
20165 * src/reader.c (yylsp_needed): Remove this variable, now replaced
20166 with `locationsflag'.
20167 * doc/bison.texinfo: Document `--locations' and `%locations'.
20169 * tests/calc.m4: Test it.
20171 For regularity of the names, replace each
20172 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
20173 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
20174 In addition replace each `flag' with `_flag'.
20176 2000-10-02 Akim Demaille <akim@epita.fr>
20178 Also test parse error messages, including with YYERROR_VERBOSE.
20180 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
20182 Use it to check the computations.
20183 Use it to check `nonassoc' is honored.
20184 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
20185 `--yyerror-verbose'.
20186 (_AT_CHECK_CALC): Adjust to this option.
20187 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
20189 2000-10-02 Akim Demaille <akim@epita.fr>
20191 Test also `--verbose', `--defines' and `--name-prefix'. Testing
20192 the latter demonstrates a flaw in the handling of non debugging
20193 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
20194 was used in order to simplify:
20210 unfortunately this leads to a CPP conflict when
20211 `--name-prefix=foo' is used since it produces `#define yydebug
20214 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
20215 (YYDPRINTF): New macro.
20217 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
20219 Also test `--verbose', `--defines' and `--name-prefix'.
20221 2000-10-02 Akim Demaille <akim@epita.fr>
20223 Improve the readability of the produced parsers.
20225 * src/bison.s1: Formatting changes.
20226 Improve the comment related to the `$' mark.
20227 (yydefault): Don't fall through to `yyresume': `goto' there.
20228 * src/output.c (output_parser): When the `$' is met, skip the end
20230 New variable, `number_of_dollar_signs', to check there's exactly
20231 one `$' in the parser skeleton.
20233 2000-10-02 Akim Demaille <akim@epita.fr>
20235 * lib/xstrdup.c: New file, from the fileutils.
20236 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
20237 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
20238 instead of strlen + xmalloc + strcpy.
20239 * src/symtab.c (copys): Remove, use xstrdup instead.
20241 2000-10-02 Akim Demaille <akim@epita.fr>
20243 * src/gram.h (associativity): New enum type which replaces the
20244 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
20245 `right_assoc', `left_assoc' and `non_assoc'.
20246 Adjust all dependencies.
20247 * src/reader.c: Formatting changes.
20248 (LTYPESTR): Don't define it, use it as a literal in
20249 `reader_output_yylsp'.
20250 * src/symtab.h (symbol_class): New enum type which replaces the
20251 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
20252 `sunknown', `stoken and `snterm'.
20254 2000-10-02 Akim Demaille <akim@epita.fr>
20256 * src/getargs.c (fixed_outfiles): Rename as...
20257 (yaccflag): for consistency and accuracy.
20258 Adjust dependencies.
20260 2000-10-02 Akim Demaille <akim@epita.fr>
20262 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
20263 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
20264 difficult and introduced a lot of core dump. It turns out that
20265 Bison used an implementation of `xmalloc' based on `calloc', and
20266 at various places it does depend upon the initialization to 0. I
20267 have not tried to isolate the pertinent places, and all the former
20268 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
20269 someone should address this issue.
20271 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
20272 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
20274 Adjust dependencies.

20278 2000-10-02 Akim Demaille <akim@epita.fr>
20280 Various anti-`extern in *.c' changes.
20282 * src/system.h: Include `assert.h'.
20284 2000-10-02 Akim Demaille <akim@epita.fr>
20286 * src/state.h (nstates, final_state, first_state, first_shift)
20287 (first_reduction): Move their exportation from here...
20288 * src/LR0.h: to here.
20289 Adjust dependencies.
20290 * src/getargs.c (statisticsflag): New variable.
20291 Add support for `--statistics'.
20292 Adjust dependencies.
20294 Remove a lot of now useless `extern' statements in most files.
20296 2000-10-02 Akim Demaille <akim@epita.fr>
20298 * src/LR0.h: New file.
20301 2000-10-02 Akim Demaille <akim@epita.fr>

20315 Adjust dependencies.
20316 * src/conflicts.h: New file.

20327 * src/reduce.h: New file.
20328 Propagate its inclusion.
20329 * src/reduce.c: Topological sort and other formatting changes.
20330 (bool, TRUE, FALSE): Move their definition to...
20331 * src/system.h: here.
20333 2000-10-02 Akim Demaille <akim@epita.fr>
20335 * src/files.c: Formatting changes.
20336 (tryopen, tryclose, openfiles): Rename as...
20337 (xfopen, xfclose, open_files): this.
20338 (stringappend): static.
20339 * src/files.h: Complete the list of exported symbols.

20362 * src/lalr.c: Formatting changes, topological sorting etc.
20364 2000-10-02 Akim Demaille <akim@epita.fr>
20366 * src/output.c (token_actions): Introduce a temporary array,
20367 YYDEFACT, that makes it possible for this function to use
20368 output_short_table.
20370 2000-10-02 Akim Demaille <akim@epita.fr>
20372 `user_toknums' is output as a `short[]' in `output.c', while it is
20373 defined as a `int[]' in `reader.c'. For consistency with the
20374 other output tables, `user_toknums' is now defined as a table of
20377 * src/reader.c (user_toknums): Be a short table instead of an int
20379 Adjust dependencies.

20390 order to get rid of the `static' prototypes.
20391 No longer use `register'.

20404 functions, use of closure.h.
20405 (initialize_closure, finalize_closure): Rename as...
20406 (new_closure, free_closure): these. Adjust dependencies.
20407 * src/LR0.c: Formatting changes, topological sort, use of
20409 (initialize_states): Rename as...
20410 (new_states): this.

20417 Don't define PARAMS.
20418 * src/system.h: Define PARAMS.
20419 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
20420 purpose of config.h. system.h must not try to fix wrong
20421 definitions in config.h.
20423 2000-09-20 Akim Demaille <akim@epita.fr>
20425 * src/derives.h: New file.

20547 complain.c::complain.
20548 (toomany): Remove, use fatal instead.

20550 * src/main.c (main): Register `done' to `atexit'.

20618 (copy_comment): Likewise.
20620 2000-03-17 Akim Demaille <akim@epita.fr>
20622 * src/reader.c (packsymbols): Formatting changes.

20635 (copy_guard): Likewise.
20637 2000-03-17 Akim Demaille <akim@epita.fr>
20639 Change the handling of @s so that they behave exactly like $s.
20640 There is now a pseudo variable @$ (readble and writable), location
20641 of the lhs of the rule (by default ranging from the location of
20642 the first symbol of the rhs, to the location of the last symbol,
20643 or, if the rhs is empty, YYLLOC).
20645 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
20647 (yyparse): When providing a default semantic action, provide a
20648 default location action.
20649 (after the $): No longer change `*YYLSP', just stack YYLOC the
20650 same way you stack YYVAL.
20651 * src/reader.c (read_declarations): Use warns.
20652 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
20653 (copy_action, case '@'): Likewise.
20654 Use a standard error message, to save useless work from
20657 2000-03-17 Akim Demaille <akim@epita.fr>

20675 2000-03-16 Akim Demaille <akim@epita.fr>
20677 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
20678 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
20679 One `#if YYDEBUG' remains, since it uses variables which are
20680 defined only if `YYDEBUG != 0'.
20682 2000-03-16 Akim Demaille <akim@epita.fr>
20684 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
20685 and related variables so that the similarities are highlighted.

21337 1995-10-15 Richard Stallman <rms@gnu.org>
21339 * src/vmsgetargs.c, src/getargs.c:
21340 Added -n, -k, and -raw switches.

21348 Revise error message.
21349 (print_notices): Remove final `.' from error message.
21351 * src/reader.c (reader_output_yylsp):
21353 (readgram): Use `#if 0' around code that accepted %command
21354 inside grammar rules: The documentation doesn't allow it,
21355 and it will fail since the %command processors scan for the next %.
21356 (parse_token_decl): Extended the %token
21357 declaration to allow a multi-character symbol as an alias.
21358 (parse_thong_decl): New function.
21359 (read_declarations): Added %thong declarations.
21360 (read_declarations): Handle NOOP to deal with allowing
21361 % declarations as another means to specify the flags.
21362 (readgram): Allow %prec prior to semantics embedded in a rule.
21363 (skip_to_char, read_declarations, copy_definition)
21364 (parse_token_decl, parse_start_decl, parse_type_decl)
21365 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
21366 (get_type_name, copy_guard, copy_action, readgram)
21367 (get_type, packsymbols): Revised most error messages.
21368 Changed `fatal' to `warnxxx' to avoid aborting for error.
21369 Revised and use multiple warnxxx functions to avoid using VARARGS1.
21370 (read_declarations): Improve the error message for
21371 an invalid character. Do not abort.
21372 (read_declarations, copy_guard, copy_action): Use
21373 printable_version to avoid unprintable characters in printed output.
21374 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
21375 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
21376 Allow the type of a non-terminal can be given
21377 more than once, as long as all specifications give the same type.
21380 (output_headers, output_trailers, output, output_gram)
21381 (output_rule_data): Implement noparserflag variable.
21382 Implement toknumflag variable.
21383 (output): Call reader_output_yylsp to output LTYPESTR.
21385 * src/main.c (main):
21386 If reader sees an error, don't process the grammar.
21387 (fatals): Updated to not use VARARGS1.
21388 (printable_version, int_to_string, warn, warni, warns, warnss)
21389 (warnsss): New error reporting functions. Avoid abort for error.
21392 Added THONG and NOOP for alias processing.
21393 Added SETOPT for the new code that allows setting options with %flags.
21396 Include getopt.h. Add some extern decls.
21397 (safegetc): New function to deal with EOF gracefully.
21398 (literalchar); new function to deal with reading \ escapes.
21399 (lex): Use literalchar.
21400 (lex): Implemented "..." tokens.
21401 (literalchar, lex, parse_percent_token): Made tokenbuffer
21402 always contain the token. This includes growing the token
21403 buffer while reading an integer.
21404 (parse_percent_token): Replaced if-else statement with percent_table.
21405 (parse_percent_token): Added % declarations as another
21406 way to specify the flags -n, -l, and -r. Also added hooks for
21407 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
21408 major changes to files.c.
21409 (lex) Retain in the incoming stream a character following
21411 (skip_white_space, lex): Revised most error messages
21412 and changed fatal to warn to avoid aborting.
21413 (percent_table): Added %thong declarations.
21415 * src/gram.h: Comment changes.
21417 * src/files.c (openfiles, open_extra_files, done):
21419 and actfile file. Handle noparserflag. Both for -n switch.
21421 * src/conflicts.c (resolve_sr_conflict):
21422 Remove use of alloca.
