722 2008-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
724 Fix dependence on computed configure variables.
725 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not
726 $(top_srcdir)/configure.ac so that changes to computed variables, such
727 as PACKAGE_VERSION, are seen.
728 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
730 2008-07-20 Joel E. Denny <jdenny@ces.clemson.edu>

751 .prev-version, and .version.
752 * NEWS (2.3b+): Rename to...
753 (?.?): ... this because we're dropping the "+" version naming scheme,
754 but, in general, we still can't be sure of our next release name.
755 * bootstrap: Add a quick hack to remove from .gitignore the
756 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
757 entry. This should really be fixed in gnulib instead.
758 * bootstrap.conf (gnulib_modules): Add gnumakefile.
759 * configure.ac (AC_INIT): Set version name by invoking

788 2008-07-15 Joel E. Denny <jdenny@ces.clemson.edu>
790 Fix some .gitignore and .cvsignore problems.
791 * bootstrap (insert_sorted_if_absent): Replace all uses with...
792 (insert_vc_ignore): ... this new function, which prepends `/' to all
793 .gitignore entries before passing them to insert_sorted_if_absent.
794 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that

810 Improve forward-compatibility with GNU M4. Reported by Eric Blake at
811 <http://lists.gnu.org/archive/html/bug-bison/2008-07/msg00000.html>.
812 * bootstrap.conf (gnulib_modules): Add unsetenv.
813 * lib/.gitignore, lib/.cvsignore (/unsetenv.c): Add.
814 * m4/.gitignore, m4/.cvsignore (/environ.m4): Add.
816 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
817 the first argument because it may become position-dependent, and unset
818 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
819 Add comments explaining these issues in more detail.
821 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

877 2008-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
879 * THANKS: Add Eric Blake.
881 2008-04-23 Eric Blake <ebb9@byu.net>
883 Revert prior patch, by working around autoconf regression.
884 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
885 ("Output file name: ("): Uncomment test.
886 ("Output file name: )"): Likewise.
887 Based on an idea from Noah Misch.
889 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
891 Work-around an Autoconf 2.62 AT_SETUP bug that was not present in

905 Update to the current gnulib CVS repository, and fix trigraph handling
907 * bootstrap: Update gnulib CVS repository URL.
908 (symlink_to_dir): Encapsulate the code that guarantees the destination
909 directory exists into...
910 (check_dst_dir): ... this new function, and...
911 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
912 fail when copying files into lib/uniwidth/.
913 * src/output.c (prepare_symbols): When writing yytname muscles, where
914 symbol names will be encoded in C-string literals, tell quotearg to
915 escape trigraphs. This used to be the default in gnulib.
916 * tests/regression.at (Token definitions): Because of the change in
917 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
918 escapes trigraphs in symbol names. Thus, yytname no longer has
919 trigraphs unnecessarily doubly escaped. Update test case output.
920 Extend test case to be sure Bison's own error messages will no longer
921 have trigraphs in symbol names unnecessarily escaped once.
923 2008-04-20 Joel E. Denny <jdenny@ces.clemson.edu>

935 * NEWS (2.3a+): Mention that -g now takes an argument.
936 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
937 consistency. Update the -g and -x entries now that they take
938 arguments. Use brackets to indicate optional arguments.
939 * src/getargs.c (usage): Explain the relationship between arguments of
940 long and short options more completely. Document --defines and -d
941 separately since the former takes an argument but, for POSIX Yacc, the
943 (short_options): Let -W take an optional argument like --warnings.
944 (getargs): Sort cases.
946 2008-02-28 Akim Demaille <demaille@gostai.com>

958 -g and -x take optional arguments, just like their long options.
959 * build-aux/cross-options.pl: Use /x to make the regexp easier to
961 Fix the handling of $opt which resulted in all the argument to be
962 considered as optional.
964 2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>

1000 * data/yacc.c: Clean up whitespace in the output a little.
1001 (yypstate_allocated): Define for impure push parsers regardless of
1002 whether the pull interface is also requested.
1003 * tests/push.at (Push Parsing: Multiple impure instances): Extend to
1004 check impure push parsers without the pull interface.
1006 * data/yacc.c (yypstate_new): Don't try to invoke yyerror since
1007 yyerror takes arguments specified by %parse-param while yypstate_new

1596 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
1597 inside a new table in the general %define entry. Document `%define

1599 explains it more completely in the case of C++.
1600 (C++ Bison Interface): Mention `%define namespace' instead of
1602 (Table of Symbols): Remove the `%define push_pull' entry. The %define
1604 * tests/c++.at (Relative namespace references): New test case.
1605 (Absolute namespace references): New test case.
1606 (Syntactically invalid namespace references): New test case.

1698 parsing requests here...
1699 * data/yacc.c: ... hack this to switch to push.c any time
1700 b4_use_push_pull_flag or the %define variable push_pull is set. This
1701 will go away when we mv push.c yacc.c.
1702 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
1703 push parsing is not supported since unused %define variables are

1924 (getargs): Remove -n case in the switch here.
1925 * src/getargs.h (no_parser_flag): Remove extern.
1926 * tests/regression.at (Web2c Actions): Remove comment that mentions
1929 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
1931 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
1932 name user variables starting with `yy'. Just pass NULL instead of a
1933 dummy local &yylval to yypush_parse.
1934 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
1937 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
1939 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
1940 true since it's then always used regardless of whether yyoverflow is
1941 defined. Reported by Christian Burger at
1942 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
1943 * THANKS: Add Christian Burger.
1945 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
1946 node names: say "Decl Summary" not "Bison Declaration Summary".
1948 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
1950 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
1951 determine whether this function has already complained about an invalid
1952 value for a %define boolean variable, don't check whether Bison has
1953 ever examined the value. As written, the check was a tautology.
1954 Instead, record and check for this complaint using a separate muscle.
1956 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
1958 Fix push parsing memory leak reported by Brandon Lucia at
1959 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
1960 * THANKS: Add Brandon Lucia.
1961 * data/push.c (yypstate_delete): Free the stack if it was reallocated
1962 but the parse never completed and thus freed it.
1963 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
1964 * tests/testsuite.at: Include push.at.
1965 * test/push.at: New.
1966 (Push Parsing: Memory Leak for Early Deletion): New test case.
1968 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
1970 Improve handling of multiple S/R conflicts in the same state and of S/R
1971 conflicts involving multiple reductions.
1972 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
1973 set for a state here or Bison will abort if it is reassigned on a
1974 later conflicted reduction in the same state.
1975 Similarly, don't finalize and assign the solved conflicts report here
1976 or it will be lost if it is reassigned on a later conflicted reduction
1978 (set_conflicts): Instead, assign them both here after all S/R conflicts
1979 in the state have been fully examined.
1980 * src/print.c (shift_set): Rename to...
1981 (no_reduce_set): ... this.
1982 (print_reductions): Update for rename, and add %nonassoc error action
1983 tokens to no_reduce_set so that, when printing the first remaining
1984 reduction on an error action token, the reduction is enclosed in
1986 (print_results): Update for rename.
1987 * tests/conflicts.at (Solved conflicts report for multiple reductions
1988 in a state): New test case.
1989 (%nonassoc error actions for multiple reductions in a state): New test
1992 * src/main.c (main): Don't depend on C99 features.
1994 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
1996 * build-aux/.cvsignore: Add compile.
1997 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
2000 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
2002 * bootstrap (slurp): Create target directories that don't exist.
2003 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
2005 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
2007 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
2009 * closure.c (closure): Likewise.
2010 * state.h (reductions): Comment sorting of rules.
2011 (state): Comment sorting of items.
2013 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
2015 Fix C++ test cases after recent Gnulib changes. Discussed starting at
2016 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
2017 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
2018 definition in order to avoid Gnulib headers since we don't use config.h
2020 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
2021 rather than AT_DATA so that config.h is included.
2023 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
2025 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
2026 instead of fprintf. Guard these functions with #if YYDEBUG instead of
2027 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
2028 and so that YYFPRINTF is guaranteed to be defined here.
2030 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
2032 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
2034 (muscle_percent_define_check_values): ... this more helpful function.
2035 Again, it's not used yet, but it will be.
2036 * src/muscle_tab.h: Likewise.
2038 Improve some comments in parser table construction.
2039 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
2040 (generate_states): Don't mention ruleset, which is internal to closure.
2041 * src/closure.c (closure): Explain sorting of core and itemset, which
2042 is required for this function to behave correctly.
2043 * src/closure.h (closure): Mention sorting.
2045 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
2047 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2048 move the check for disabled transitions to an aver since conflict
2049 resolution hasn't happened yet.
2051 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
2052 labels a state as inconsistent just because it has error transitions.
2053 The original form of this check appeared in revision 1.1 of lalr.c,
2054 which was committed on 1991-12-21. Now (at least), changing the
2055 consistency label on such a state appears to have no useful effect in
2056 any of the places it is examined, which I enumerate below. The key
2057 point to understanding each item in this enumeration is that a state
2058 with an error transition is labelled consistent in the first place only
2059 if it has no rules, so the check cannot matter for states that have
2060 rules. (1) Labelling a state as inconsistent will cause set_conflicts
2061 to try to identify its conflicts, and a state must have *rules* to have
2062 conflicts. (2) Labelling a state as inconsistent will affect how
2063 action_row sets the default *rule* for the state. (3) Labelling a
2064 state as inconsistent will cause build_relations to add lookback edges
2065 to *rules* in that state.
2066 * src/state.h (struct state): Word the comment for member consistent
2069 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
2071 Don't depend on C99 features.
2072 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
2073 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
2074 * src/reader.c (check_and_convert_grammar): Fix for-loop.
2075 * src/state.c (state_mark_reachable_states): Fix for-loop.
2076 (state_remove_unreachable_states): Fix for-loop.
2078 Don't widen struct state with member reachable just to temporarily
2079 record reachability. Instead, use a local bitset.
2080 * src/state.h (struct state): Remove member.
2081 * src/state.c (state_new): Don't initialize it.
2082 (state_mark_reachable_states): Rename to...
2083 (state_record_reachable_states): ... this, and use bitset.
2084 (state_remove_unreachable_states): Use bitset.
2086 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
2088 * src/Makefile.am (yacc): Quote target action commands properly so
2089 that the yacc script isn't corrupt. Reported by Hans Aberg at
2090 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
2092 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
2093 the case of pure parsers. Reported by Frans Englich at
2094 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
2095 * THANKS: Add Frans Englich.
2097 * NEWS (2.3a+): In the %code entry, reference section `Bison
2098 Declaration Summary' from the manual now since the %code summary has
2100 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
2101 in the rules section must be terminated by semicolons.
2103 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
2105 Extend the front-end API for %define variables to more completely
2106 mirror the back-end. This will be useful in the future.
2107 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
2108 Update comments to mention the new front-end counterparts of these

2129 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
2130 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
2131 tests/existing.at: Update copyright date.
2133 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
2135 If conflict resolution makes states unreachable, remove those states,
2136 report rules that are then unused, and don't report conflicts in those

2158 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
2159 (new_itemsets, save_reductions): Update for rename to nitemset.
2160 * src/closure.c (nritemset): Rename to...

2284 * tests/input.at (%define errors): Update expected output.
2285 * tests/skeletons.at (%define boolean variables: invalid skeleton

2290 * src/print.c (lookahead_set, state_default_rule): Remove.
2291 (print_reductions): Replace state_default_rule invocation with
2292 equivalent use of yydefact, which was computed in token_actions in
2294 (print_results): Don't allocate lookahead_set.
2296 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
2298 * data/lalr1.java: Prefix all private members with yy.
2300 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
2302 Use YYFPRINTF instead of fprintf where appropriate. Reported by
2303 Sebastien Fricker at

2320 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
2322 Undo my 2007-02-07 change, switching back to the c-strcase module
2323 introduced in the 2007-02-03 change. Bruno Haible reported that
2324 the 2007-02-07 change would be dangerous in Turkish if we add a
2325 language whose name contains "i", since "i" is not lowercase "I"
2327 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.

2348 * src/reader.c (packgram): Move translation of rule actions from the
2349 beginning of packgram to...
2350 (check_and_convert_grammar): ... here right before packgram is invoked
2351 so it's easier to write more complete comments, and remove redundant
2354 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
2356 As in semantic actions, make @$ in %initial-action, %destructor, and
2357 %printer imply %locations.
2358 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
2360 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
2361 (@$ in %initial-action implies %locations,
2362 @$ in %destructor implies %locations,
2363 @$ in %printer implies %locations): ... these new test cases.
2365 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
2367 Undo most of the 2007-02-03 change, switching to the strcase module
2368 now that gnulib strcase has been fixed.
2369 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
2370 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
2371 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
2372 * m4/.cvsignore: Add strcase.m4.
2373 * src/getargs.c: Revert 2007-02-03 change, as follows.
2374 Don't include c-strcase.h.
2375 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
2376 strcasecmp has "unspecified behavior" outside the POSIX locale,
2377 but it works fine in practice if at least one argument is ASCII,
2378 as is the case in Bison.
2380 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
2382 * tests/java.at: Skip tests if only one of javac/java is present.
2383 Reported by Joel E. Denny.
2384 * tests/atlocal.in: Adjust copyright years.
2386 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
2388 * data/lalr1.java (Stack): Work around old verifiers that disallow
2389 access to the private fields of an inner class, from the outer class.
2390 We can make Stack's fields public because user code doesn't have access
2391 to the instance of Stack used by parse(). Reported by Paul Eggert.
2393 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
2395 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
2396 the right spot for these files?
2397 * bootstrap.conf (gnulib_modules): Add c-strcase.
2398 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
2400 * src/getargs.c: Include c-strcase.h.
2401 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
2402 to avoid unspecified behavior.
2404 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
2406 * doc/bison.texinfo (Decl Summary): Correct typo.
2408 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
2410 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
2411 Complain if the value does not match empty, "true" or "false".
2412 * data/c++.m4: Adjust default definitions of %define variables.
2413 * data/java.m4: Adjust default definitions of %define variables.
2414 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
2416 * tests/input.at (Boolean %define variables): Test new behavior.
2418 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
2420 * NEWS: Mention java.
2421 * TODO: Remove things that are done.
2422 * bootstrap.conf: Add javacomp-script and javaexec-script.
2423 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
2425 * data/Makefile.am: Add new files.
2426 * data/java-skel.m4: New.
2427 * data/java.m4: New.
2428 * data/lalr1.java: New.
2430 * doc/bison.texinfo: Put "A Complete C++ Example" under
2431 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
2432 under Other Languages.
2434 * src/getargs.c (valid_languages): Add Java.
2435 * src/getargs.h (struct bison_language): Update size of string fields.
2437 * tests/Makefile.am: Add java.at.
2438 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
2439 * tests/java.at: New.
2440 * tests/testsuite.at: Include it.
2442 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
2445 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
2446 at_directive_argv arguments so these no longer have to be global
2447 variables. Also, update the implementation for the following changes.
2448 (fail_for_at_directive_too_many_args,
2449 fail_for_at_directive_too_few_args): Add at_directive_name argument.
2450 (at_directive_name): Remove as at_directive_argv[0] will be used for
2452 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
2453 for the directive name.
2454 (at_directive_argc, at_directive_argv): Make these local within
2455 skel_lex instead of global.
2456 (INITIAL): Update directive start action for above changes.
2457 (SC_AT_DIRECTIVE_ARG): Rename to...
2458 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
2459 (SC_AT_DIRECTIVE_SKIP_WS): Update.
2460 (scan_skel): Move yylex_destroy to...
2461 (skel_scanner_free): ... here.
2462 * tests/skeletons.at (installed skeleton file name): Rename to...
2463 (installed skeleton file names): ... this.
2465 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
2467 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
2468 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
2469 Summary" not "Directives".
2470 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
2471 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
2472 since the former is now the more complete one.
2473 (Prologue Alternatives): Likewise and do the same for %defines.
2474 (Table of Symbols): Add summary of %code, add summary of %define, and
2475 move full %code documentation to...
2476 (Decl Summary): ... here for consistency with other entries in these
2478 Move %define entry in order to keep this list alphabetized.
2479 Reword %define entry a little to put less emphasis on the skeleton
2480 concept, which most users shouldn't have to think about.
2482 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
2484 Adjust to recent gnulib changes.
2485 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
2486 Add string.h, string_.h, unistd_.h, wchar_.h.
2487 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
2488 * src/system.h: Don't include <stpcpy.h>; this is now done by
2491 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
2493 Simplify implementation of unqualified %code, implement macros for
2494 uniform treatment of boolean %define flags. Document %define.
2495 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
2496 b4_percent_code_ifdef): New.
2497 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
2498 * data/c++.m4: Define default value for global_tokens_and_yystype.
2499 * data/glr.cc: Likewise.
2500 * data/location.cc: Use b4_percent_define_flag_if.
2502 * doc/bison.texinfo (Decl Summary): Document %define.
2504 * src/parse-gram.y (Unqualified %code): Change muscle name to
2506 (content.opt): Default to empty.
2508 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
2510 Implement support for relative and absolute skeleton file names.
2511 Discussed starting at
2512 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
2513 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
2514 (Bison Options): Document in --skeleton entry.
2515 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
2516 full_skeleton can't necessarily hold all of pkgdatadir.
2517 If the specified skeleton file name contains a `/', don't prepend
2519 * src/parse-gram.y (prologue_declaration): If the specified skeleton
2520 file name contains a `/', prepend the grammar file directory.
2521 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
2522 * skeletons.at: New file.
2523 (relative skeleton file names): New test case.
2524 (installed skeleton file names): New test case.
2525 * tests/testsuite.at: Include skeletons.at.
2527 * bootstrap: Update copyright to 2007.
2529 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
2531 * bootstrap: Remove occurrences of .#bootmp from the files.
2533 2007-01-17 Akim Demaille <akim@epita.fr>
2535 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
2537 Use per-type %printer.
2539 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>

2549 2007-01-16 Akim Demaille <akim@epita.fr>
2551 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
2553 (Calc++ Scanner): Exit with failure if we can't open the input
2555 Accept "-" standing for stdin.
2556 (Calc++ Top Level): Print the result only if the parsing was

2561 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
2563 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
2564 and Joel E. Denny <jdenny@ces.clemson.edu>
2566 Clean up %define and %code implementation in M4 some. Most
2567 importantly, rename all related macros to be in the b4_percent_define
2568 and b4_percent_code namespaces. Also, complete support for `.' in
2569 %define variable names and %code qualifiers.
2570 * data/bison.m4 (b4_check_user_names): Check for special
2571 "SKELETON-NAMESPACE(name)" macros instead of using two nested
2573 (b4_get_percent_define, b4_get_percent_code): Rename to...
2574 (b4_percent_define_get, b4_percent_code_get): ... these.
2575 Extend documentation with examples.
2576 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
2577 b4_percent_define_skeleton_variables and
2578 b4_percent_code_skeleton_qualifiers.
2579 Expect any value for the %define variable `foo' to be stored in the
2580 macro named `b4_percent_define(foo)'; expect any %code blocks for the
2581 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
2582 expect any unqualified %code blocks to be stored in a macro named
2583 `b4_percent_code_unqualified'.
2584 Use m4_indir so that %define variable names and %code qualifiers can
2585 contain `.', which is allowed by the grammar parser.
2586 (b4_percent_define_default): New macro to set a default value for a
2588 (m4_wrap): Update wrapped code, and fix some underquoting.
2589 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
2590 Expect grammar uses of %define variables and %code qualifiers to be
2591 defined in b4_percent_define_user_variables and
2592 b4_percent_code_user_qualifiers.
2593 * data/c++.m4: Use b4_percent_define_default rather than
2594 m4_define_default. Fix some underquoting. Skeleton usage of %define
2595 variable define_location_comparison now implies skeleton usage of
2596 %define variable filename_type.
2597 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
2598 data/push.c, data/yacc.c: Update macro names.
2599 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
2602 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
2604 DJGPP specific issues.
2606 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
2607 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
2609 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2611 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
2612 run parsers in all tests so that Valgrind is invoked during
2613 maintainer-check-valgrind.
2614 (Duplicate representation of merged trees): Free all semantic values.
2615 (Duplicated user destructor for lookahead): Likewise.
2617 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2619 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
2620 command-line prefix.
2621 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
2622 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
2623 miss Valgrind messages.
2624 (Exploding the Stack Size with Malloc): Likewise.
2626 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2628 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
2629 locals. Reported by Juan Manuel Guerrero at
2630 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
2631 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
2632 Fix some indentation also.
2633 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
2634 explaining this issue.
2636 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
2637 and Joel E. Denny <jdenny@ces.clemson.edu>
2639 Simplify union and prologue handling, and escape union and lex/parse
2640 params with digraphs.
2641 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
2642 values to the empty string since these are no longer guaranteed
2643 initialized by the front-end.
2644 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
2645 braces around b4_user_stype since this is no longer done by the
2647 * src/files.c, src/files.h (pre_prologue_obstack,
2648 post_prologue_obstack): Remove.
2649 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
2650 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
2651 with digraphs. This fixes lex params and parse params.
2652 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
2653 * src/output.c (prepare): Remove muscle insertion of the prologues.
2654 (output): Remove freeing of pre_prologue_obstack and
2655 post_prologue_obstack.
2656 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
2657 than prologue_augment for prologue parsing so you don't need prologue
2659 (grammar_declaration): For %union RHS, use `braceless' instead of
2660 "{...}" so that braces are already stripped and code is escaped with
2662 * src/reader.c (prologue_augment): Remove.
2663 (reader): Remove initialization of pre_prologue_obstack and
2664 post_prologue_obstack.
2665 * src/reader.h (prologue_augment): Remove.
2667 * data/c.m4: Remove stray parenthesis.
2669 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2671 Remove quotes from variables names in %define directives and from
2672 qualifiers in %code directives, and restrict the characters that are
2673 allowed in them to M4-friendly ones. For %define, continue to support
2674 the quoted form as a deprecated feature. Discussed starting at
2675 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
2676 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
2678 * doc/bison.texinfo (Prologue Alternatives): Update.
2679 (Decl Summary): In %defines entry, update mention of `%code requires'
2680 and `%code provides'.
2681 (C++ Location Values): Update %define uses.
2682 (Calc++ Parser Interface): Likewise.
2683 (Calc++ Parser): Likewise, and update `%code requires' uses.
2684 (Table of Symbols): Update %code documentation.
2685 * src/parse-gram.y (prologue_declaration): For %define variables, use
2686 `variable' instead of `STRING'.
2687 (grammar_declaration): For %code qualifiers, use `ID' instead of
2689 (variable): New nonterminal that takes an `ID' or a `STRING'.
2690 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
2692 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
2693 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
2694 (%define errors): Update %define uses.
2696 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2698 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
2699 instead of muscle_insert for %define values so that M4-special
2700 characters are replaced with digraphs.
2701 * tests/input.at (%define errors): Extend to check weird values.
2703 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2705 Instead of having skeletons declare all valid %define variables and
2706 %code qualifiers, provide macros that retrieve the associated values
2707 and build these lists automatically. Thus Bison will now warn when a
2708 variable or qualifier is not used by the skeleton in the current
2709 invocation regardless of whether it might sometimes be used by that
2710 skeleton in other invocations. Also, move all %define value macros to
2711 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
2712 form, which is replaced by %code.
2713 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
2714 (b4_check_user_names): ... this, and change the series of valid name
2715 arguments to a single list argument for names used in the skeleton
2716 similar to the existing list argument for names used in the grammar.
2717 Warn instead of complaining.
2718 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
2719 values and %code code, to format %code code properly, and to build
2720 lists of all %define variables and %code qualifiers used in the
2721 skeleton: b4_skeleton_percent_define_variables and
2722 b4_skeleton_percent_code_qualifiers.
2723 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
2725 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
2726 the skeleton names lists can finish building first. In place of
2727 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
2728 expect the lists b4_user_percent_define_variables and
2729 b4_user_percent_code_qualifiers.
2730 * data/c++.m4: Where setting default values for b4_parser_class_name,
2731 b4_location_type, b4_filename_type, b4_namespace, and
2732 b4_define_location_comparison, update their names to the
2733 b4_percent_define_ namespace.
2734 * data/glr.c: Don't use b4_check_percent_define_variables and
2735 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2736 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
2737 (b4_parser_class_name, b4_namespace): Define these using
2738 b4_get_percent_define for parser_class_name and namespace.
2739 * data/location.cc: Use b4_get_percent_define.
2740 * data/push.c: Don't use b4_check_percent_define_variables and
2741 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2742 * data/yacc.c: Likewise, and don't call m4_exit in
2743 b4_use_push_for_pull_if or m4_wrap code will never execute.
2744 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
2746 (muscle_grow_user_name_list): ... this for consistency with the
2747 terminology used in bison.m4.
2748 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
2749 %define variable names, and rename muscle used_percent_define_variables
2750 to user_percent_define_variables.
2751 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
2752 user_percent_code_qualifiers.
2754 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
2755 {CODE} form is no longer accepted.
2756 * tests/input.at (Reject bad %code qualifiers): Rename to...
2757 (Reject unused %code qualifiers): ... this, and update test output.
2758 (%define error): Update test output.
2760 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
2762 Check for unrecognized %define variables similar to checking for
2763 unrecognized %code qualifiers. Check for redefined %define variables.
2764 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
2766 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
2767 (b4_check_percent_define_variables): New, also wraps it.
2768 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
2769 variables using b4_check_percent_define_variables.
2770 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
2771 all those exercised in the test suite and all those listed in the
2772 `Default values' section of c++.m4. Are there others?
2773 * data/push.c, data/yacc.c: Declare no valid %define variables.
2774 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
2775 similar to muscle_find, but it works even when the muscle stores a
2777 (muscle_grow_used_name_list): New function for constructing the used
2778 name list muscles that b4_check_for_unrecognized_names requires.
2779 * src/parse-gram.y (prologue_declaration): Warn if a variable is
2780 %define'd more than once. Define the b4_used_percent_define_variables
2781 muscle with muscle_grow_used_name_list.
2782 (grammar_declaration): Abbreviate %code code with
2783 muscle_grow_used_name_list.
2784 * tests/input.at (%define errors): New.
2786 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2788 Provide warn_at, complain_at, and fatal_at function callbacks to the
2789 skeletons, and use this for %code qualifier complaints.
2790 * data/bison.m4 (b4_error_at): New, invoked by...
2791 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
2792 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
2793 @fatal_at(...@) directives.
2794 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
2795 qualifiers in b4_used_percent_code_qualifiers and to use
2797 * src/location.c, src/location.h (boundary_set_from_string): New global
2799 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
2801 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
2802 to b4_used_percent_code_qualifiers.
2803 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
2805 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
2806 (lineno): Rename to...
2807 (out_lineno): ... this so I don't misunderstand it again.
2808 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
2809 here; these newlines are in the input but not the output file.
2810 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
2811 (at_directive_perform): ... this new static function, and add handling
2812 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
2814 * tests/input.at (Reject bad %code qualifiers): Update test output with
2815 locations and extend.
2817 * tests/output.at (Output file name: [, Output file name: ]): Remove
2818 bogus comment about these tests failing.
2820 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2822 Clean up b4_check_percent_code_qualifiers a little.
2823 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
2824 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
2825 documentation and add examples.
2826 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
2829 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
2831 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
2832 unreliable -- especially when they're hidden inside another macro.
2833 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
2834 data/c.m4: Remove m4_divert(-1).
2835 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
2836 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
2837 m4_divert_push(0) and m4_divert_pop(0).
2838 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
2839 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
2840 pushed and popped by m4sugar, should be first on the stack.
2842 Provide warn, complain, and fatal function callbacks to the skeletons.
2843 This provides more flexibility than m4_fatal, improves the error
2844 message format, and captures messages for translation. Discussed
2846 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
2847 * data/bison.m4 (b4_error): New, invoked by...
2848 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
2849 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
2850 directives. Because these M4 macros might be called when the current
2851 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
2852 the previous removal of uses of m4_divert, which caused trouble.
2853 (b4_check_percent_code_qualifiers): Use b4_complain instead of
2854 m4_fatal to report unrecognized %code qualifiers.
2855 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
2856 push parser requests.
2857 * data/glr.c: Use b4_complain instead of m4_fatal to report
2858 non-deterministic push parser requests.
2859 Update @output usage to @output(...@) form.
2860 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
2861 report missing %defines. Update @output usage to @output(...@) form.
2862 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
2864 * src/main.c (main): Invoke skel_scanner_free.
2865 * src/scan-skel.h (skel_scanner_free): Prototype new function.
2866 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
2867 obstack_for_string from flex-scanner.h.
2868 (YY_DECL): Use to declare skel_lex static.
2869 (decode_at_digraphs): Remove; now handled in the new
2870 SC_AT_DIRECTIVE_ARG start condition.
2871 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
2873 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
2874 at_directive_argv): New static globals.
2875 (INITIAL): Use fail_for_invalid_at.
2876 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
2877 recognize the start of a generalized `@directive(...@)' form and
2879 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
2880 directive args (using the new obstack_for_string), to decode the
2881 contained @ diagraphs, and to perform the directive. It recognizes
2882 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
2884 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
2885 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
2887 (scan_skel): Initialize obstack_for_string on the first call.
2888 (skel_scanner_free): New function to free obstack_for_string.
2889 * tests/input.at (Reject bad %code qualifiers): Update test output.
2891 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
2893 Consolidate the 4 prologue alternative directives (%code, %requires,
2894 %provides, and %code-top) into a single %code directive with an
2895 optional qualifier field. Discussed at
2896 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
2897 * NEWS (2.3a+): Rewrite the existing entry for the prologue
2899 * doc/bison.texinfo (Prologue Alternatives): Update.
2900 (Decl Summary): Update to %code "requires" and %code "provides".
2901 (Calc++ Parser): Update to %code "requires".
2902 (Table of Symbols): Remove entries for %requires, %provides, and
2903 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
2904 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
2905 are replaced by b4_percent_code_provides and b4_percent_code_requires,
2906 which are skeleton-specific.
2907 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
2908 declare what %code qualifiers it supports and to complain if any other
2909 qualifiers were used in the grammar.
2910 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
2911 and b4_user_code([b4_percent_code_provides]) in place of
2912 b4_user_requires and b4_user_provides.
2913 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
2914 Add b4_user_code([b4_percent_code_top]) and
2915 b4_user_code([b4_percent_code]).
2916 Invoke b4_check_percent_code_qualifiers.
2917 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2918 PERCENT_REQUIRES): Remove.
2919 (grammar_declaration): Remove RHS's for %code-top, %provides, and
2920 %requires. Rewrite the %code RHS as the unqualified form defining the
2921 muscle b4_percent_code. Add another RHS for the qualified %code form,
2922 which defines muscles of the form b4_percent_code_QUALIFIER and the
2923 b4_used_percent_code_qualifiers muscle.
2924 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2925 PERCENT_REQUIRES): Remove.
2926 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
2927 %code "requires" and %code "provides".
2928 * tests/input.at (Reject bad %code qualifiers): New.
2930 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2932 Use the new code_props interface for destructors and printers.
2933 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
2934 printer_location members, and change the type of the destructor and
2935 printer members to code_props.
2936 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
2937 symbol_printer_get, semantic_type_destructor_set,
2938 semantic_type_printer_set, default_tagged_destructor_set,
2939 default_tagless_destructor_set, default_tagged_printer_set,
2940 default_tagless_printer_set): Use code_props in arguments and return
2941 types in place of char const * and location.
2942 (symbol_destructor_location_get, symbol_printer_location_get): Remove
2943 since the locations are now contained in the return of
2944 symbol_destructor_get and symbol_printer_get.
2945 * src/output.c (symbol_destructors_output, symbol_printers_output):
2947 (symbol_code_props_output): ... this to eliminate duplicate code.
2948 (output_skeleton): Update to use symbol_code_props_output.
2949 * src/reader.c (symbol_should_be_used): Update use of
2950 symbol_destructor_get.
2951 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
2952 Update uses of the various _destructor_set and _printer_set functions.
2953 * src/symtab.c: (default_tagged_destructor_location,
2954 default_tagless_destructor_location, default_tagged_printer_location,
2955 default_tagless_printer_location): Remove since we...
2956 (default_tagged_destructor, default_tagless_destructor,
2957 default_tagged_printer, default_tagless_printer): ... change the type
2958 of these to code_props.
2959 (symbol_new, semantic_type_new, symbol_destructor_set,
2960 semantic_type_destructor_set, symbol_destructor_get,
2961 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
2962 symbol_check_alias_consistency, default_tagged_destructor_set,
2963 default_tagless_destructor_set, default_tagged_printer_set,
2964 default_tagless_printer_set): Update.
2965 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
2966 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
2968 (symbol_print): Use SYMBOL_CODE_PRINT.
2970 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2972 Use the new code_props interface for rule actions.
2973 * src/symlist.h (symbol_list): Replace action, action_location, and
2974 used members with a code_props action_props member.
2975 * src/reader.c (symbol_should_be_used, grammar_rule_check,
2976 grammar_midrule_action, grammar_current_rule_merge_set,
2977 grammar_current_rule_symbol_append, packgram): Update.
2978 * src/scan-code.h (translate_rule_action): Remove, no longer used.
2979 * src/scan-code.l (handle_action_dollar): Update.
2980 (translate_rule_action): Remove, no longer used.
2981 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
2983 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
2985 Use the new code_props interface in parse-gram.y.
2986 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
2987 Update all uses of translate_* functions to use the new code_props
2988 interface and to use gram_scanner_last_string_free and
2989 code_scanner_last_string_free where possible.
2990 (grammar_declaration): symbol_list_destructor_set and
2991 symbol_list_printer_set now perform the translation, so don't do it
2992 here. Use gram_scanner_last_string_free where possible.
2993 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
2994 translate_code): Remove, no longer used.
2995 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
2996 symbol_list_printer_set): Perform code translation here rather than
2997 depending on the caller to do so.
2999 * src/symlist.h (struct symbol_list): Correct some documentation typos.
3000 * src/scan-gram.h (gram_last_string): Remove declaration.
3001 * src/scan-gram.l (last_string): Declare it static.
3003 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3005 Encapsulate code properties and related functionality for the various
3006 destructors, printers, and actions into a code_props structure and
3007 interface. This patch merely implements code_props in scan-code.h and
3008 scan-code.l. Future patches will rewrite other modules to use it.
3009 Discussed starting at
3010 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
3011 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
3012 consistently initialize const structs that have an empty location
3014 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
3015 to ensure consistency.
3016 * src/scan-code.h (code_props): New structure.
3017 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
3018 function, macro, and const global variable for initializing a
3019 code_props with no code.
3020 (code_props_plain_init, code_props_symbol_action_init,
3021 code_props_rule_action_init, code_props_translate_code): The rest of
3022 the new code_props functional interface. Among other things, the init
3023 functions set the code_props kind field so that
3024 code_props_translate_code will know whether to behave like
3025 translate_symbol_action, translate_rule_action, or translate_code.
3026 These old translate functions must remain until all other modules are
3027 updated to use the new code_props interface.
3028 (code_scanner_last_string_free): New function similar to
3029 gram_scanner_last_string_free.
3030 (code_scanner_free): Add documentation.
3031 * src/scan-code.l: Implement the new interface.
3032 (code_lex): Make it static, add a code_props* argument, and remove the
3034 (last_string): New static global similar to the one in scan-gram.l.
3035 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
3037 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
3038 code_props since Bison may one day use this information for destructors
3040 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
3041 (handle_action_dollar): Use symbol_list_n_get and set used flag
3042 directly since symbol_list_n_used_set is removed.
3043 (translate_action): Add a code_props* argument and remove the rule,
3044 action, and location arguments. Pass the code_props* on to code_lex.
3045 (translate_rule_action, translate_symbol_action, translate_code):
3046 Rewrite as wrappers around the new code_props interface.
3047 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
3048 it would eventually need to break the encapsulation of code_props.
3050 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3052 * etc/.cvsignore: New.
3054 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3056 Add maintainer-push-check to run maintainer-check using push parsing in
3057 place of pull parsing where available.
3058 * Makefile.am (maintainer-push-check): New.
3059 * data/bison.m4 (b4_use_push_for_pull_if): New.
3060 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
3061 appropriately based on their existing values.
3062 (yypush_parse): Don't print push-parser-specific diagnostics if push
3063 parsing is being used in place of pull parsing.
3064 * data/yacc.c: If push parsing should replace pull parsing, redirect to
3066 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
3067 variable, and insert b4_use_push_for_pull_flag into muscles.
3068 * tests/Makefile.am (maintainer-push-check): New.
3070 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3072 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
3073 (whether successful or failed) so that yypush_parse can be invoked
3074 again to start a new parse using the same yypstate.
3075 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
3076 check multiple yypull_parse invocations on the same yypstate. For pull
3077 mode, extend to check multiple yyparse invocations.
3078 (Exploding the Stack Size with Alloca): Extend to try with
3080 (Exploding the Stack Size with Malloc): Likewise.
3082 * tests/calc.at (Simple LALR Calculator): Don't specify
3083 %skeleton "push.c" since %push-pull-parser implies that now.
3084 * tests/headers.at (export YYLTYPE): Don't check for the push
3085 declarations. Otherwise, this test case can't be used to see if push
3086 mode can truly emulate pull mode.
3087 * tests/input.at (Torturing the Scanner): Likewise.
3088 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
3089 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
3090 AT_YACC_IF, which now includes the case of push mode since %skeleton
3091 need not be used for push mode. This will be more intuitive once
3092 push.c is renamed to yacc.c.
3094 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3096 For push mode, convert yyparse from a macro to a function, invoke yylex
3097 instead of passing a yylexp argument to yypull_parse, and don't
3098 generate yypull_parse or yyparse unless %push-pull-parser is declared.
3099 Discussed starting at
3100 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
3101 * data/bison.m4 (b4_pull_if): New.
3102 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
3103 * data/push.c: Improve M4 quoting a little.
3104 (b4_generate_macro_args, b4_parenthesize): Remove.
3105 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
3106 any time a pull parser is requested.
3107 Don't #define this as a wrapper around yypull_parse. Instead, when
3108 both push and pull are requested, make it a function that does that
3110 (yypull_parse): If there's a b4_prefix, #define this to
3111 b4_prefix[pull_parse] when both push and pull are requested.
3112 Don't define this as a function unless both push and pull are
3114 Remove the yylexp argument and hard-code yylex invocation instead.
3115 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
3117 * src/getargs.c (pull_parser): New global initialized to true.
3118 * getargs.h (pull_parser): extern it.
3119 * src/output.c (prepare): Insert pull_flag muscle.
3120 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
3121 (prologue_declaration): Set both push_parser and pull_parser = true for
3122 %push-pull-parser. Set push_parser = true and pull_parser = false for
3124 * src/scan-gram.l: Don't accept %push_parser as an alternative to
3125 %push-parser since there's no backward-compatibility concern here.
3126 Scan %push-pull-parser.
3127 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
3128 instead of %push-parser.
3129 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
3130 prototype it in the module that calls yyparse.
3131 * tests/input.at (Torturing the Scanner): Likewise.
3132 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
3134 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
3136 Update etc/bench.pl. Optimize push mode a little (the yyn change
3137 deserves most of the credit).
3138 * Makefile.am (SUBDIRS): Add etc subdirectory.
3139 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
3140 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
3141 yytoken, yyval, and yyloc declarations to...
3142 (yyparse or yypush_parse): ... here to improve performance. For
3143 yypush_parse invocations after the first, be sure to assign yyn its old
3145 (yypstate_new): Don't bother initializing the yyresult field since the
3146 initial value isn't used.
3147 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
3148 remove the #define that, in push mode, set it to yyps->NAME.
3149 * etc/Makefile.am: New.
3150 * etc/bench.pl: Remove and build it instead from...
3151 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
3152 "tests/bison" from the build directory by default rather than just
3153 invoking "bison" from $PATH.
3154 (calc_grammar): Update push parser code: don't declare yylval globally,
3155 don't define yyparse_wrapper, and don't #define yyparse.
3156 (bench_grammar): Update to check all working combinations of yacc.c,
3157 push.c, impure, pure, pull, and push.
3159 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3161 For push mode, add pull wrappers around yypush_parse.
3162 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
3163 (yypull_parse): New function wrapping yypush_parse.
3164 (yyparse): New #define wrapping yypull_parse.
3165 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
3167 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
3168 prototype yylex in the module that calls yyparse, and don't prototype
3169 yyparse there. Otherwise, the yyparse expansion won't compile.
3170 * tests/input.at (Torturing the Scanner): Likewise.
3172 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3174 Enable push parsers to operate in impure mode. Thus, %push-parser no
3175 longer implies %pure-parser. The point of this change is to move
3176 towards being able to test the push parser code by running the entire
3177 test suite as if %push-parser had been declared.
3178 * data/push.c (yypush_parse): For impure mode, remove the
3179 yypushed_char, yypushed_val, and yypushed_loc arguments.
3180 Instead, declare these as local variables initialized to the global
3181 yychar, yylval, and yylloc.
3182 For the first yypush_parse invocation only, restore the initial values
3183 of these global variables when it's time to read a token since they
3184 have been overwritten.
3185 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
3187 * tests/calc.at (Simple LALR(1) Calculator): Always declare
3188 %pure-parser along with %push-parser since this test case was designed
3189 for pure push parsers.
3190 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
3191 (AT_YACC_OR_PUSH_IF): New.
3192 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
3193 add a note that it's still wrong for some cases (as it has been for a
3195 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
3196 %push-parser no longer implies %pure-parser.
3198 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3200 Remove some unnecessary differences between the pull parser code and
3201 the push parser code. This patch enables yynerrs in push mode.
3202 * data/push.c: Reformat M4 a little.
3203 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
3204 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
3205 because push mode is on. Instead, if pure mode is on, move yynerrs
3207 (b4_declare_parser_state_variables): ... here.
3208 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
3209 to yyps->NAME so it can be used in yypush_parse.
3210 (yypush_parse): Don't omit uses of yynerrs in push mode.
3212 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3214 Fix bug such that the first pushed token's value and location are
3215 sometimes overwritten (sometimes by %initial-action) before being used.
3216 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
3217 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
3218 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
3219 more closely mimic the pull parser logic.
3220 Don't copy the pushed token to yychar, yylval, and yylloc until it's
3221 time to read a token, which is after any initialization of yylval and
3223 (gottoken): Rename label to...
3224 (yyread_pushed_token): ... for clarity and to avoid infringing on the
3227 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3229 Rearrange initialization of the parser state variables so that the
3230 skeleton doesn't have to have a copy for pull mode and another for push
3231 mode. This patch also fixes at least a bug such that yylloc was not
3232 initialized (with b4_location_initial_line and
3233 b4_location_initial_column) upon calling yypush_parse. However, that
3234 initialization now overwrites the first token's location;
3235 %initial-action assigning @$ already did the same thing, and both bugs
3236 will be fixed in a later patch.
3237 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
3238 (b4_declare_parser_state_variables): Remove initialization of yytoken,
3239 yyss, yyvs, yyls, and yystacksize.
3240 (yypstate_new): Remove initialization of some yypstate fields: yystate,
3241 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
3243 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
3244 yyps->NAME so it can be used in yypush_parse.
3245 (yyparse or yypush_parse): For yypush_parse, don't print the
3246 "Starting parse" diagnostic for invocations after the first.
3247 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
3248 yypush_parse, only do it for the first invocation.
3249 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
3250 initialization to occur in yypush_parse but only on the first
3253 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3255 * data/push.c: Add CPP guards around push parser declarations in both
3256 the header and the code file.
3257 In the code file, move the push parser declarations to the same place
3258 they appear in the header file.
3259 Clean up the M4 some, especially the inconsistent underquoting in
3260 some b4_c_function_def and b4_c_function_decl uses.
3262 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3264 Encapsulate the push parser state variables into an M4 macro so the
3265 push skeleton doesn't have to list them again for pull mode's yyparse.
3266 For push mode, remove yypush_parse's local equivalents of these
3267 variables to eliminate unnecessary copying between the two sets at
3268 run-time. This patch also fixes at least a bug related to multiple
3269 %initial-action invocations in push mode.
3270 * data/push.c (b4_declare_parser_variables): Rename to...
3271 (b4_declare_scanner_communication_variables): ... this for clarity and
3273 (b4_declare_yyparse_variables): Remove and move its contents to the one
3274 spot where it was invoked.
3275 (b4_declare_parser_state_variables): New macro containing the parser
3276 state variables required by push mode.
3277 (struct yypstate): Replace all fields but yynew with
3278 b4_declare_parser_state_variables.
3279 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
3280 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
3281 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
3282 (yyparse or yypush_parse): For yyparse in pull mode, replace local
3283 parser state variable declarations with
3284 b4_declare_parser_state_variables.
3285 Don't initialize parser state variables when calling yypush_parse since
3286 yypstate_new already does that.
3287 Invoke the user's initial action only upon the first yypush_parse
3289 Remove all code that copies between the local parser state variables
3292 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3294 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
3295 prevent a name collision in a future patch where these names will
3296 sometimes be #define'd.
3297 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
3298 since it no longer has the same name as the existing argument.
3299 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
3301 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
3302 and Joel E. Denny <jdenny@ces.clemson.edu>
3304 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
3305 that the argument is case-insensitive, and there's no `=' here.
3306 For the %skeleton entry, mention that %language is better.
3307 (Bison Options): Likewise for --language and --skeleton. Move the
3308 --skeleton entry so that the `Tuning the parser' section is sorted
3309 alphabetically on long options.
3310 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
3311 %language directive in detail here; cross-reference the %language
3312 documentation instead.
3313 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
3314 `%require "2.3b"' so that the example is always up-to-date.
3315 (Table of Symbols): Add entries for %language and %skeleton.
3316 * examples/extexi (normalize): Instead of replacing every %require
3317 argument with the current Bison version, just substitute for
3318 `@value{VERSION}'. This guarantees that we're testing what actually
3319 appears in the documentation.
3320 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
3321 rather than `@VERSION@'.
3323 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3325 * NEWS: Reword the %language news a bit, and put it earlier.
3327 * src/getargs.c (skeleton_arg): Last arg is now location const *.
3328 Rewrite to simplify the logic.
3329 (language_argmatch): Likewise.
3330 (program_name): We now own this var.
3331 * src/getargs.h (struct bison_language): Use char[] rather than
3334 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
3336 * src/complain.c (program_name): Remove decl; no longer needed.
3337 * src/main.c (program_name): Remove; now belongs to getargs.
3339 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
3341 * NEWS: Document %language.
3343 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
3345 * data/c-skel.m4, data/c++-skel.m4: New files.
3346 * data/glr.c: Complain on push parsers.
3348 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
3350 (Decl Summary): Document %language and %skeleton.
3351 (Command line): Document -L.
3353 * examples/extexi: Rewrite %require directive.
3354 * examples/calc++/Makefile.am: Pass VERSION to extexi.
3356 * src/files.c (compute_exts_from_gc): Look in language structure
3358 (compute_file_name_parts): Check whether .tab should be added.
3359 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
3360 (language, skeleton_arg, language_argmatch): New.
3361 (long_options): Add --language.
3362 (getargs): Use skeleton_arg, add -L/--language.
3363 * src/getargs.h: Include location.h.
3364 (struct bison_language, language, skeleton_arg, language_argmatch): New.
3365 * src/output.c (prepare): Pick default skeleton from struct language.
3366 Don't dispatch C skeletons here.
3367 * src/parse-gram.y (PERCENT_LANGUAGE): New.
3368 (prologue_declaration): Add "%language" rule, use skeleton_arg.
3369 * src/scan-gram.l ("%language"): New rule.
3371 * tests/calc.at: Test %skeleton and %language.
3372 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
3373 (AT_GLR_IF): Look for %skeleton "glr.cc".
3374 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
3375 (AT_YACC_IF): Reject %language.
3377 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3379 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
3380 since it wasn't used; only the typedef name 'semantic_type' is needed.
3381 Also, omit trailing white space.
3383 * bootstrap: Sync from coreutils.
3384 (gnulib_extra_files): Add build-aux/announce.gen.
3385 (slurp): Adjust .gitignore files like .cvsignore files.
3386 * build-aux/announce-gen: Remove from CVS, since bootstrap
3389 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
3391 Make %push-parser imply %pure-parser. This fixes several bugs; see
3392 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
3393 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
3395 * data/push.c: Don't bother testing b4_push_if when deciding whether
3396 to expand b4_declare_parser_variables globally.
3397 (yypush_parse): Likewise in here.
3399 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
3400 (yy_reduce_print): Reformat M4 for readability.
3402 2006-12-15 Bob Rossi <bob@brasko.net>
3403 and Joel Denny <jdenny@ces.clemson.edu>
3405 * data/push.c (yypstate): Add typedef, and update all uses of
3406 struct yypstate to just yypstate.
3407 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
3409 2006-12-14 Bob Rossi <bob@brasko.net>
3411 * data/push.c (yypush_parse): Declare prototype regardless of
3414 2006-12-14 Bob Rossi <bob@brasko.net>
3416 * data/push.c (yyparse): Remove the prototype and the #define when in
3419 2006-12-13 Bob Rossi <bob@brasko.net>
3421 * data/push.c (yypstate_init): Rename to...
3422 (yypstate_new): ... this and use b4_c_function_def.
3423 (yypstate_delete): New.
3424 (yypush_parse): Change parameters yynval and yynlloc to be const.
3425 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
3426 yypstate_delete functions.
3428 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
3430 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
3431 strange test case titles. Reported by Bob Rossi.
3433 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
3435 * TODO: Add pointer to Sylvain Schmitz's work on static detection
3436 of potential ambiguities in GLR grammers.
3438 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
3440 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
3441 `bison ', use m4_index instead of m4_substr since chopping up a string
3442 containing M4-special characters causes problems here.
3444 Fix a couple of bugs related to special characters in user-specified
3445 file names, and make it easier for skeletons to compute output file
3446 names with the same file name prefix as Bison-computed output file
3448 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
3449 b4_parser_file_name and b4_spec_defines_file instead of
3450 @output_parser_name@ and @output_header_name@, which are now redundant.
3451 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
3452 b4_parser_file_name, b4_spec_defines_file, and the new
3453 @basename(FILENAME@) instead of @output_parser_name@ and
3454 @output_header_name@, which inappropriately escaped the file names as
3456 * src/files.c (all_but_ext): Remove static qualifier.
3457 (compute_output_file_names): Move `free (all_but_ext)' to...
3458 (output_file_names_free): ... here since all_but_ext is needed later.
3459 * src/files.h (all_but_ext): Extern.
3460 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
3461 exactly what MUSCLE_INSERT_STRING used to do.
3462 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
3463 characters are escaped properly.
3464 * src/output.c (prepare): Define muscle file_name_all_but_ext as
3466 For pkgdatadir muscle, maintain previous functionality by using
3467 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
3468 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
3469 digraphs would never be expanded. Hopefully no one has M4-special
3470 characters in his Bison installation path.
3471 * src/scan-skel.l: Don't parse @output_header_name@ and
3472 @output_parser_name@ anymore since they're now redundant.
3473 In @output, use decode_at_digraphs.
3474 Parse a new @basename command that invokes last_component.
3475 (decode_at_digraphs): New.
3476 (BASE_QPUTS): Remove unused.
3477 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
3478 (Output file name): New tests.
3480 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
3482 Warn about output files that are generated by the skeletons and that
3483 conflict with other output files.
3484 * data/glr.c: Don't generate the header file here when glr.cc does.
3485 * src/files.c (file_names, file_names_count): New static globals.
3486 (compute_output_file_names): Invoke output_file_name_check for files
3487 not generated by the skeletons and remove existing checks.
3488 (output_file_name_check): New function that warns about conflicting
3490 (output_file_names_free): Free file_names.
3491 * src/files.h (output_file_name_check): Declare.
3492 * src/scan-skel.l: Invoke output_file_name_check for files generated by
3494 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
3495 (Conflicting output files): New tests.
3497 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3499 * doc/bison.texinfo: Fix a couple of typos.
3501 2006-12-08 Bob Rossi <bob@brasko.net>
3503 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
3505 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
3507 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
3508 (yypush_parse): Rename yypvars argument to yyps and remove redundant
3510 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
3511 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
3513 2006-12-07 Bob Rossi <bob@brasko.net>
3514 and Joel Denny <jdenny@ces.clemson.edu>
3516 * data/push.c (yypvarsinit): Change return type from void* to struct
3517 yypvars*. No longer cast to void* on return.
3518 (struct yypvars): Remove yylen since it need not be remembered between
3519 yypushparse invocations.
3520 (yypushparse): Don't copy between yylen and pv->yylen.
3522 2006-12-05 Bob Rossi <bob@brasko.net>
3524 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
3525 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
3526 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
3527 (struct yypvars): Remove b4_declare_parser_variables.
3528 (yypvarsinit): Remove init code for removed variables.
3529 (global scope): Do not declare b4_declare_parser_variables if
3531 (yypushparse): Add b4_declare_parser_variables.
3532 Init new local variables, and remove init code for removed
3535 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
3536 and yyparse for other modes.
3537 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
3538 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
3539 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
3540 (AT_PURE_LEX_IF): True if pure or push parser.
3542 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>

3618 grammar is maintained with Bison's highest standards.

3621 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
3623 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
3624 later. Reported by Paul Eggert in
3625 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
3626 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
3627 * src/scan-code.l (translate_action): Don't bother invoking
3628 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
3629 (code_scanner_free): Instead of invoking
3630 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

3638 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
3639 has been called previously for the same key.

3643 could potentially be NULL when value is not.

3661 since they are freed.
3662 * src/files.c: Likewise.

3671 src_extension, and header_extension.
3672 (output_file_names_free): New public function to free
3673 spec_verbose_file, spec_graph_file, spec_defines_file,
3674 parser_file_name, and dir_prefix.

3677 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
3678 (which previously existed but was unused), and quotearg_free.

3680 * src/muscle_tab.c: Likewise.
3681 (muscle_entry): Make the value char const *,
3682 and add a new storage member that is char * and can be freed.
3683 (muscle_entry_free): New private function.
3684 (muscle_init): Use it instead of free.
3685 (muscle_insert, muscle_grow): Update and use new storage member.
3686 (muscle_code_grow): Free the string passed to muscle_grow
3687 since it's not needed anymore.
3688 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
3689 add a new `char *code' member.

3699 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
3701 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
3703 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
3704 expecting a non-zero exit status sets --leak-check=summary and
3705 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
3706 this case, and we don't want to hear about it.
3708 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3710 * bootstrap (runtime-po/Makevars): Derive from po/Makevars

3727 declarations): Run tests with and without --warnings=midrule-values.
3729 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather

3751 empty subargument list. For example: `bison --warnings= parser.y'.
3753 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
3755 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
3756 the parser header file so that gcc doesn't warn.
3758 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>

3809 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
3810 like $@n instead of just @n so that the default %destructor/%printer
3811 logic doesn't see them as user-defined symbols.
3812 (symbol_is_dummy): Check for both forms of the name.
3813 * src/reader.c (packgram): Remove the `$' from each midrule symbol
3814 name for which the midrule value is referenced in any action.

3842 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
3844 Similar to the recently removed %before-header, add %code-top as the

3957 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
3958 variable was sometimes used without being initialized. This
3959 messed up the installation of the INSTALL file in some cases.
3961 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
3963 * bootstrap (usage, main program, symlink_to_gnulib): Add option
3964 --copy. Inspired by a suggestion from Bruno Haible.
3966 2006-10-03 Jim Meyering <jim@meyering.net>
3968 * bootstrap: Undo last change to this file, since now gnulib-tool
3969 sticks with the automake default in generating dependencies.
3971 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3973 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

4118 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
4119 to copies-of-gnulib.
4120 (cp_mark_as_generated, slurp, gnulib_files):
4121 Avoid making a copy if it's the same as the old version.
4122 (gnulib_files): Add support for this variable (used by Bison).
4124 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
4126 * src/getargs.c (usage): Rework to use conventions similar to
4127 coreutils, to make translation a bit easier and the code a bit
4128 smaller. Problem reported by Tim Van Holder.
4130 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
4132 Use some of gnulib's new modules, taken from coreutils.
4134 * bootstrap: Sync from coreutils, except add support for gnulib_files.
4135 * bootstrap.conf: New file.
4136 (gnulib_modules): Add configmake, inttypes, unistd.
4137 (XGETTEXT_OPTIONS): Add complain, complain_at,
4138 fatal, fatal_at, warn, warn_at, unexpected_end.
4139 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
4140 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
4142 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
4144 (GNULIB_AUTOCONF_SNIPPET): Remove.
4145 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
4147 * lib/.cvsignore: Add inttypes_.h.
4148 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
4149 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
4150 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
4151 no-longer-necessary initializations.
4152 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
4153 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
4154 use the unistd module.
4155 * src/system.h: Likewise.
4156 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
4157 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
4158 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
4159 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
4160 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
4161 * src/system.h: Include inttypes.h unconditionally, now that we
4162 use the inttypes module. Don't bother to include stdint.h, since
4163 inttypes.h now does that for us.
4164 (LOCALEDIR): Remove, now that we use the configmake module.
4165 * src/getargs.c: Include configmake.h.
4166 * src/main.c: Likewise.
4167 * src/output.c: Likewise.
4168 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
4169 not from $abs_top_builddir, since config.h moved.
4172 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
4173 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
4175 * src/parse-gram.y (symbol_declaration): Don't put statements
4176 before declarations; it's not portable to C89.
4177 * src/scan-code.l (handle_action_at): Likewise.
4179 * src/scan-code.l: Always initialize braces_level; the old code
4180 left it uninitialized and therefore had undefined behavior.
4182 Don't attempt to redefine 'assert', since it runs afoul of
4183 systems where standard headers (mistakenly) include <assert.h>.
4184 Instead, define and use our own alternative, called 'aver'.
4185 * src/reader.c: Don't include assert.h, since we no longer
4187 * src/scan-code.l: Likewise.
4188 * src/system.h (assert): Remove, replacing with....
4189 (aver): New function, taking a bool arg. All uses changed.
4190 * src/tables.c (pack_vector): Ensure that aver arg is bool,
4191 not merely an integer.
4193 2006-09-15 Bob Rossi <bob@brasko.net>
4195 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
4196 * data/c.m4 (YYPUSH): New.
4197 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
4198 * src/getargs.c (push_parser): New var.
4199 * src/getargs.h (push_parser): New declaration.
4200 * src/output.c (prepare): Add macro insertion of `push_flag'.
4201 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
4202 (prologue_declaration): Parse %push-parser.
4203 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
4204 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
4205 list of removed lines from the traces observed.
4206 (AT_CHECK_CALC_LALR): Added push parser tests.
4208 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
4210 * NEWS: Version 2.3a.
4211 * configure.ac (AC_INIT): Likewise.
4213 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
4214 "#define YYSTYPE int" that caused "make maintainer-check" to fail
4215 due to header ordering dependencies. I don't know why the #define
4218 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
4219 runtime cost when YYDEBUG is not defined, and so that some tests
4220 that used to fail now work. Problem and initial suggestion by
4222 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
4223 * data/glr.cc (b4_parser_class_name):
4224 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
4225 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
4226 (yydebug_) [YYDEBUG]: New member.
4227 (yycdebug_): Now defined only if YYDEBUG.
4228 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
4229 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
4230 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
4232 (debug_stream, set_debug_stream, debug_level, set_debug_level):
4233 Define only if YYDEBUG.
4234 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
4236 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
4237 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
4238 AT_CHECK_CALC_GLR_CC that are working now.
4240 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
4242 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
4243 We don't need them in glr.cc, and glr.c defines them.
4244 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
4245 assumes that defining it to anything is the same as defining
4246 it to 1. Problem reported by Paolo Bonzini.
4248 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
4250 * data/c.m4 (b4_null, b4_case): Define.
4251 * src/output.c (prepare_symbols): Use b4_null.
4252 (user_actions_output): Use b4_case.
4254 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
4256 * data/glr.c (b4_shared_declarations): Put start-header first,
4257 before any #includes that we generate, so that feature-test
4258 macros work. Problem reported by Michael Deutschmann in
4259 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
4260 * data/lalr1.cc: Likewise.
4261 * doc/bison.texinfo (Prologue): Document that feature-test macros
4262 should be defined before any Bison declarations.
4263 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
4264 that depend on location.hh after, not before, Bison decls, since
4265 we now include location.hh after the first user prologue.
4267 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
4268 Sander Brandenburg in
4269 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
4270 Also, fix minor white space and comment issues.
4271 (Prologue): Mention that it's better to define feature-test macros
4272 before Bison declarations. Problem reported by Michael Deutschmann.
4274 * README-cvs: Fix typo: "&" should be "&&". Problem reported
4276 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
4277 This adjusts to recent gnulib changes.
4279 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4281 Finish implementation of per-type %destructor/%printer. Discussed
4283 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
4285 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
4286 * NEWS (2.3+): Add a description of this feature to the default
4287 %destructor/%printer description.
4288 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
4289 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4290 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
4291 list node contains a semantic type.
4292 * src/symtab.c, src/symtab.h: Extend with a table that associates
4293 semantic types with their %destructor's and %printer's.
4294 (semantic_type_from_uniqstr, semantic_type_get,
4295 semantic_type_destructor_set, semantic_type_printer_set): New functions
4296 composing the public interface of that table.
4297 (symbol_destructor_get, symbol_destructor_location_get,
4298 symbol_printer_get, symbol_printer_location_get): If there's no
4299 per-symbol %destructor/%printer, look up the per-type before trying
4301 * tests/actions.at (Per-type %printer and %destructor): New test case.
4302 * tests/input.at (Default %printer and %destructor redeclared):
4303 Extend to check that multiple occurrences of %symbol-default in a
4304 single %destructor/%printer declaration is an error.
4305 (Per-type %printer and %destructor redeclared, Unused values with
4306 per-type %destructor): New test cases.
4308 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4310 Require default %destructor/%printer to be declared using
4311 %symbol-default instead of an empty symbol list, and start working on
4312 new per-type %destructor/%printer. Discussed at
4313 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
4314 * NEWS (2.3+): Add %symbol-default to example.
4315 * bison.texinfo (Freeing Discarded Symbols): Likewise.
4316 (Table of Symbols): Add entry for %symbol-default.
4317 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
4318 (generic_symlist, generic_symlist_item): New nonterminals for creating
4319 a list in which each item is a symbol, semantic type, or
4321 (grammar_declaration): Use generic_symlist in %destructor and %printer
4322 declarations instead of symbols.1 or an empty list.
4323 (symbol_declaration, precedence_declaration, symbols.1): Update actions
4324 for changes to symbol_list.
4325 * src/reader.c: Update for changes to symbol_list.
4326 * src/scan-code.l: Likewise.
4327 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
4328 * src/symlist.c, src/symlist.h: Extend such that a list node may
4329 represent a semantic type or a %symbol-default in addition to just an
4330 ordinary symbol. Add switched functions for setting %destructor's and
4332 * tests/actions.at, tests/input.at: Add %symbol-default to all default
4333 %destructor/%printer declarations.
4335 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
4337 Whether the default %destructor/%printer applies to a particular symbol
4338 isn't a question of whether the user *declares* that symbol (in %token,
4339 for example). It's a question of whether the user by any means
4340 *defines* the symbol at all (by simply using a char token, for
4341 example). $end is defined by Bison whereas any other token with token
4342 number 0 is defined by the user. The error token is always defined by
4343 Bison regardless of whether the user declares it with %token, but we
4344 may one day let the user define error as a nonterminal instead.
4345 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
4346 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
4347 the meaning of "user-defined".
4348 * tests/actions.at (Default %printer and %destructor for user-declared
4349 end token): Rename to...
4350 (Default %printer and %destructor for user-defined end token): ...
4353 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
4354 computation of whether to apply the default, don't maintain a list of
4355 every Bison-defined symbol. Instead, just check for a first character
4356 of '$', which a user symbol cannot have, and check for the error token.
4358 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
4360 Don't apply the default %destructor or %printer to the error token,
4361 $undefined, or $accept. This change fits the general rule that the
4362 default %destructor and %printer are only for user-declared symbols,
4363 and it solves several difficulties that are described in the new test
4365 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
4366 * tests/actions.at (Default %printer and %destructor are not for error
4367 or $undefined, Default %printer and %destructor are not for $accept):
4370 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
4372 Allow %start after the first rule.
4373 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
4374 when parsing the first rule.
4375 (check_and_convert_grammar): Search for it here after all grammar
4376 declarations have been parsed. Skip midrules, which have dummy LHS
4378 * src/symtab.c (symbol_is_dummy): New function.
4379 * src/symtab.h (symbol_is_dummy): Declare it.
4380 * tests/input.at (%start after first rule): New test.
4382 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4384 Redo some of the previous commit: add back the ability to use
4385 non-aliased/undeclared string literals since it might be useful to
4386 those declaring %token-table.
4387 * src/reader.c (check_and_convert_grammar): Undo changes in previous
4388 commit: don't worry about complaints from symbols_pack.
4389 * src/symtab.c (symbol_new, symbol_class_set,
4390 symbol_check_alias_consistency): Undo changes in previous commit: count
4391 each string literal as a new symbol and token, assign it a symbol
4392 number, and don't complain about non-aliased string literals.
4393 (symbols_pack): Since symbol_make_alias still does not decrement symbol
4394 and token counts but does still set aliased tokens to the same number,
4395 symbol_pack_processor now leaves empty slots in the symbols array.
4397 * tests/regression.at (Undeclared string literal): Remove test case
4398 added in previous commit since non-aliased string literals are allowed
4400 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
4401 remove unnecessary string literal declarations.
4402 * tests/sets.at (Firsts): Likewise.
4404 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4406 Don't allow an undeclared string literal, but allow a string literal to
4407 be used before its declaration.
4408 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
4409 symbols_pack complained.
4410 * src/symtab.c (symbol_new): Don't count a string literal as a new
4412 (symbol_class_set): Don't count a string literal as a new token, and
4413 don't assign it a symbol number since symbol_make_alias does that.
4414 (symbol_make_alias): It's not necessary to decrement the symbol and
4415 token counts anymore. Don't assume that an alias declaration occurs
4416 before any uses of the identifier or string, and thus don't assert that
4417 one of them has the highest symbol number so far.
4418 (symbol_check_alias_consistency): Complain if there's a string literal
4419 that wasn't declared as an alias.
4420 (symbols_pack): Bail if symbol_check_alias_consistency failed since
4421 symbol_pack asserts that every token has been assigned a symbol number
4422 although undeclared string literals have not.
4423 * tests/regression.at (String alias declared after use, Undeclared
4424 string literal): New test cases.
4425 (Characters Escapes, Web2c Actions): Declare string literals as
4427 * tests/sets.at (Firsts): Likewise.
4429 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
4431 In the grammar scanner, STRING_FINISH unclosed constructs and return
4432 them to the parser in order to improve error messages.
4433 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
4434 SC_BRACED_CODE, SC_PROLOGUE): Implement.
4435 * tests/input.at (Unclosed constructs): New test case.
4436 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
4439 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
4442 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
4444 Handle string aliases for character tokens correctly.
4445 * src/symtab.c (symbol_user_token_number_set): If the token has an
4446 alias, check and set its alias's user token number instead of its own,
4447 which is set to indicate the alias. Previously, every occurrence of
4448 the character token in the grammar overwrote that alias indicator with
4450 * tests/input.at (String aliases for character tokens): New test.
4452 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
4454 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
4456 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
4458 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
4459 to prevent failures when building on older platforms.
4460 Check for autopoint failure.
4461 Set XGETTEXT_OPTIONS to values that check for C format strings,
4462 so that translators are warned about them (this also helps
4463 prevent core dumps).
4465 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
4466 function, since it simplifies our code a bit.
4468 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
4469 rather than -W, so we don't get bogus warnings about sign comparisons.
4470 Add -Wpointer-arith, since that warning is useful (it reports code
4471 that does not conform to C89 and that some compilers reject).
4472 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
4473 since it's no longer needed.
4475 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
4477 Clean up scanners a bit.
4478 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
4479 definitions so gcc won't warn when obstack_for_string is unused.
4480 * src/scan-code.l: config.h and system.h are already #include'd by
4481 scan-code-c.c, so get rid of them here.
4482 * src/scan-gram.l: Likewise.
4483 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
4484 definitions rather than duplicating the rest of it.
4485 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
4487 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
4489 Suppress signed/unsigned comparison warnings for yycheck.
4490 * data/c.m4 (b4_safest_int_type): New macro.
4491 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
4492 a signed int type, cast it to b4_safest_int_type first.
4493 * data/yacc.c: Likewise.
4494 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
4497 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
4499 * doc/bison.texinfo: Fix some typos.
4501 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
4503 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
4504 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
4506 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
4507 the latest gnulib does this a different way.
4508 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
4509 translation was patched, so stop omitting it.
4511 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
4513 Enable declaration of default %printer/%destructor. Make the parser
4514 use these for all user-declared grammar symbols for which the user does
4515 not declare a specific %printer/%destructor. Thus, the parser uses it
4516 for token 0 if the user declares it but not if Bison generates it as
4517 $end. Discussed starting at
4518 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
4519 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
4521 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
4522 * NEWS (2.3+): Mention.
4523 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
4524 declare a %destructor for a mid-rule's semantic value. It's just
4525 impossible to declare one specific to it.
4526 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
4527 code. Describe default %destructor form.
4528 * src/parse-gram.y (grammar_declaration): Parse default
4529 %printer/%destructor declarations.
4530 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
4531 and symbol_destructor_location_get rather than accessing the destructor
4532 and destructor_location members of struct symbol.
4533 (symbol_printers_output): Likewise but for %printer's.
4534 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
4536 * src/symtab.c (default_destructor, default_destructor_location,
4537 default_printer, default_printer_location): New static global
4538 variables to record the default %destructor and %printer.
4539 (symbol_destructor_get, symbol_destructor_location_get,
4540 symbol_printer_get, symbol_printer_location_get): New functions to
4541 compute the appropriate %destructor and %printer for a symbol.
4542 (default_destructor_set, default_printer_set): New functions to set the
4543 default %destructor and %printer.
4544 * src/symtab.h: Prototype all those new functions.
4545 * tests/actions.at (Default %printer and %destructor): New test to
4546 check that the right %printer and %destructor are called, that they're
4547 not called for $end, and that $$ and @$ work correctly.
4548 (Default %printer and %destructor for user-declared end token): New
4549 test to check that the default %printer and %destructor are called for
4550 a user-declared end token.
4551 * tests/input.at (Default %printer and %destructor redeclared, Unused
4552 values with default %destructor): New tests to check related grammar
4553 warnings and errors.
4555 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
4557 Clean up handling of %destructor for the end token (token 0).
4558 Discussed starting at
4559 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
4561 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
4563 Make the skeletons consistent in how they pop the end token and invoke
4565 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
4566 state, which has token number 0, since this would invoke the
4567 %destructor for the end token.
4568 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
4569 until after shifting the end token, or else it won't be popped.
4570 * data/yacc.c (yyparse): Likewise.
4572 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
4573 it's the end token. Upon termination, destroy an unshifted lookahead
4574 even when it's the end token.
4575 * data/lalr1.cc (yy::parser::parse): Likewise.
4576 * data/yacc.c (yyparse): Likewise.
4578 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
4579 value warnings for the end token when the user gives the end token a
4582 * tests/actions.at (Printers and Destructors): Test all the above.
4584 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
4586 Update to latest gnulib and gettext versions.
4587 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
4589 (gnulib_files): Add m4/warning.m4. Don't worry about files
4590 overwritten by autopoint.
4591 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
4592 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
4594 Don't use autoreconf; instead, invoke autopoint etc. by hand,
4595 so that we can remove the intl files at a better time.
4596 (intl_files_to_remove): Remove aclocal.m4, since it gets
4597 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
4598 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
4599 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
4600 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
4601 Remove datarootdir hack; no longer needed.
4602 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
4603 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
4604 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
4606 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
4607 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
4609 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4611 * bootstrap: Adjust to today's change to gnulib-tool by invoking
4612 it with --assume-autoconf='latest-stable'.
4614 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
4616 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
4617 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
4619 * src/muscle_tab.h (muscle_grow): Replace the header comments with
4620 those from muscle_tab.c since the old ones are misleading.
4622 2006-07-13 Akim Demaille <akim@epita.fr>
4624 Support %define "KEY" {VALUE}.
4625 * src/scan-code.h, src/scan-code.l (translate_action)
4626 (translate_rule_action, translate_symbol_action, translate_code):
4627 Return char *, not const char *.
4628 * src/parse-gram.y (declaration): Rename as...
4629 (prologue_declaration): this.
4630 (string_content): Remove this nonterminal, use STRING.
4631 (braceless, content, content.opt): New nonterminal.
4633 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
4635 * src/scan-gram.l (getargs.h): Don't include it.
4637 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
4639 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
4640 rather than a for-loop that declares a local bool variable. This
4641 should work around a compatibility problem with a Cray x1e C++
4642 compiler reported by Hung Nguyen in
4643 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
4644 The for-loop was introduced in the 2004-11-17 change but I don't
4645 know why it was needed.
4647 2006-07-12 Akim Demaille <akim@epita.fr>
4649 * data/c.m4: Comment changes.
4651 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
4653 * src/complain.c (error_message, ERROR_MESSAGE): New.
4655 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
4656 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
4658 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4660 * NEWS: Instead of %union, you can define and use your own union type
4661 YYSTYPE if your grammar contains at least one <type> tag.
4662 Your YYSTYPE need not be a macro; it can be a typedef.
4663 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
4664 (Union Decl, Decl Summary): Document this.
4665 * data/glr.c (YYSTYPE): Implement this.
4666 * data/glr.cc (YYSTYPE): Likewise.
4667 * data/lalr1.cc (YYSTYPE): Likewise.
4668 * data/yacc.c (YYSTYPE): Likewise.
4669 * src/output.c (prepare): Output tag_seen_flag.
4670 * src/parse-gram.y (declaration, grammar_declaration):
4671 Use 'union_seen' rather than 'typed' to determine whether
4672 %union has been seen, since grammars can now be typed without
4674 (symbol_declaration, type.opt, symbol_def):
4675 Keep track of whether a tag has been seen.
4676 * src/reader.c (union_seen, tag_seen): New vars.
4678 * src/reader.h (union_seen, tag_seen, typed): Likewise.
4679 * src/scan-code.l (untyped_var_seen): New variable.
4680 (handle_action_dollar): Adjust to above changes.
4681 (handle_action_dollar, handle_action_at):
4682 Improve overflow checking for outlandish numbers.
4683 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
4684 avoid new diagnostics generated by above changes.
4685 * tests/regression.at (YYSTYPE typedef): Add test to check
4686 for type tags without %union.
4688 * src/symlist.c (symbol_list_length): Return int, not unsigned
4689 int, since callers expect int. This may need to get revisited
4690 once we have proper integer overflow checking.
4692 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
4693 object is now static.
4695 * src/getargs.c (flags_argmatch): Return void, not int,
4696 to pacify ./configure --enable-gcc-warnings.
4698 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
4699 since last_string is already defined to FLEX_PREFIX (last_string).
4701 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4703 Implement --warnings/-W.
4704 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
4706 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
4708 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
4709 (warnings_args, warnings_types): New.
4710 (getargs, short_options, long_options): Accept -W/--warnings.
4711 Sort the options by alphabetical order, upper case letter right
4712 before its lower case.
4714 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
4716 Change %merge result type clash warnings to errors. Discussed at
4717 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
4718 * src/reader.c (record_merge_function_type): Use complain_at.
4719 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4720 declared later): Update test case results.
4722 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4724 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
4725 to be in alphabetical order.
4726 (trace_args): Spelling fixes.
4728 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4730 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
4731 so they don't collide with user-defined macros.
4732 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
4733 this was never guaranteed, and now that we're using gnulib stdint,
4734 which defines int_fast16_t to long int, the problem is exposed.
4736 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
4738 * data/c.m4 (b4_basename): Simplify a bit, since we don't
4739 need the full POSIX semantics (and weren't implementing them
4742 Adjust to Autoconf 2.60 and today's gnulib.
4743 * bootstrap (gnulib_modules): Add stdint.
4744 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
4745 no longer copies it.
4746 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
4747 since stdint needs the former and wcwidth (which is now required
4748 by mbswidth) needs the latter.
4749 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
4750 work around a compatibility glitch between gettext 0.14.6 and
4752 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
4753 Do not check for uintptr_t, since new stdint module does the right
4755 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
4756 Add stdint.h, stdint_.h, wcwidth.h.
4757 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
4758 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
4759 stdint.m4, wchar_t.m4, wcwidth.m4.
4760 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
4761 usual order for ../lib/*.h files.
4762 (file_name_split): Use last_component, not base_name, to adjust
4764 * src/parse-gram.h: Include <strverscmp.h> in the usual order
4765 for ../lib/*.h files.
4766 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
4767 Define unconditionally, since we now assume the stdint module.
4768 * src/scan-skel.l: Include <dirname.h>.
4769 (BASE_QPUTS): Use last_component, not base_name.
4770 * src/system.h: Include <unlocked-io.h> in the usual order
4771 for ../lib/*.h files. Include <stdint.h> unconditionally,
4772 since we now use the stdint module.
4773 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
4774 HAVE_UINTPTR_T, since we now use the stdint module.
4775 (base_name): Remove decl, since files now include <dirname.h>
4778 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4780 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
4782 * data/yacc.c, data/glr.c, data/location.cc: Use them.
4783 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
4785 * tests/calc.at: Adjust.
4787 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4789 * data/c.m4 (b4_basename): New.
4790 (b4_syncline): Also output the location of its invocation (from
4792 (b4_user_action, b4_define_user_action, b4_user_actions)
4793 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
4794 (b4_user_stype): New.
4795 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
4797 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4799 In the grammar file, the first column is 1 not 0 on the first line as
4800 on every other line.
4801 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
4802 * tests/input.at (Torturing the Scanner): Update output.
4804 * src/scan-gram.l (scanner_cursor): Declare it static.
4806 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4808 In warnings, say "previous declaration" rather than "first
4810 * src/symtab.c (redeclaration): Do that here.
4811 * src/reader.c (record_merge_function_type): In the case of a result
4812 type clash, report the previous declaration rather than the very first
4813 one in the grammar file.
4814 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4815 declared later): Add a third declaration to check this behavior.
4816 * tests/input.at (Incompatible Aliases): Update output.
4818 2006-06-27 Akim Demaille <akim@epita.fr>
4820 * doc/Doxyfile.in: New.
4821 * doc/Makefile.am: Use it.
4822 * src/lalr.h, src/symtab.h: Initial doxygenation.
4824 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4826 Don't miss %merge result type warnings just because the LHS types are
4827 declared after the %merge. This continues the effort of the previous
4829 * src/reader.c (get_merge_function): Don't set the merger type yet.
4830 (record_merge_function_type): New function for setting the merger type
4831 and checking for clashes.
4832 (grammar_current_rule_merge_set): Set the location of the %merge for
4834 (packgram): Invoke record_merge_function_type for each rule now that
4835 all symbol type declarations have been parsed.
4836 * src/reader.h (merger_list.type_declaration_location): New member
4837 storing the location of the first %merge from which the type for this
4838 merging function was derived.
4839 * src/symlist.h (symbol_list.merger_declaration_location): New member
4840 storing the location of a rule's %merge, if any.
4841 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4842 declared later): New test to catch the error fixed by the above patch.
4844 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4846 Get action warnings (grammar_rule_check) right even when symbol
4847 declarations appear after the rules. Discussed at
4848 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
4850 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
4851 Don't mistake the type of $$ in a midrule to be that of its parent
4853 * src/reader.c (grammar_current_rule_end): Don't invoke
4854 grammar_rule_check yet since not all symbol declarations may have been
4856 (grammar_midrule_action): Likewise.
4857 Don't record whether the midrule's $$ has been used yet since actions
4858 haven't been translated yet.
4859 Record the midrule's parent rule and its RHS index within the parent
4861 (grammar_current_rule_action_append): Don't translate the action yet
4862 since not all symbol declarations may have been parsed yet and, thus,
4863 warnings about types for $$, $n, @$, and @n can't be reported yet.
4864 (packgram): Translate the action and invoke grammar_rule_check now that
4865 all symbol declarations have been parsed.
4866 * src/scan-code.l (handle_action_dollar): Now that this is invoked
4867 after parsing the entire grammar file, the symbol list here in the case
4868 of a midrule is actually the midrule's empty RHS, so reference its
4869 parent rule's RHS where necessary.
4870 On the other hand, now that you can already know it's a midrule, you
4871 aren't forced to think $$ has the same type as its parent rule's $$.
4872 (handle_action_at): In the case of a midrule, reference the parent rule
4874 * src/symlist.c (symbol_list_new): Initialize new midrule-related
4876 (symbol_list_length): Now that this is invoked after all rules have
4877 been parsed, a NULL symbol (rather than a NULL symbol list node)
4878 terminates a rule. symbol_list_print already does this correctly.
4879 * src/symlist.h (symbol_list.midrule_parent_rule,
4880 symbol_list.midrule_parent_rhs_index): New members so that midrules can
4881 remember their relationships with their parents.
4882 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
4883 fixed by the above patch.
4884 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
4886 (Unused values): ... this old test case and...
4887 (Unused values before symbol declarations): ... this new test case.
4888 This one is the same as `Unused values' except that all symbol
4889 declarations appear after the rules in order to catch the rest of the
4890 errors fixed by the above patch.
4892 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4895 * src/reader.c (current_rule): Declare it static since it's no longer
4896 used outside this file.
4897 (grammar_current_rule_action_append): Remove redundant arguments from
4898 translate_rule_action invocation.
4899 * src/reader.h (current_rule): Remove this unused extern.
4900 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
4901 * src/scan-code.l (translate_rule_action): Likewise.
4903 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
4905 Clean up yesterday's patch.
4906 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
4908 * src/reader.c (grammar_current_rule_action_append): ... here for
4909 consistency with grammar_current_rule_symbol_append.
4910 * tests/regression.at (Braced code in declaration in rules section):
4911 Make yyerror and yylex static as usual.
4913 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
4915 Fix bug that mistakes braced code in a declaration in the rules section
4916 to be a rule action. Mentioned at
4917 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
4918 * src/scan-gram.l: Move midrule action detection from the start of the
4919 scanning of any braced code to...
4920 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
4921 action. For readability, use $2 and @2 rather than the equivalent
4923 * tests/regression.at (Braced code in declaration in rules section):
4924 New test to catch the error fixed by the above patch.
4926 Work on code readability some.
4927 * src/scan-code.l (current_rule): Get rid of this misleading and
4928 redundant declaration: it's actually extern'ed in reader.h.
4929 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
4930 translate_action): Add a rule argument and use it instead of the global
4932 (translate_rule_action): This already receives current_rule through an
4933 argument, so pass it on to translate_action instead of assigning
4934 current_rule to current_rule.
4935 (translate_symbol_action, translate_code): Pass rule = NULL to
4938 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
4940 Rename %before-definitions to %start-header and %after-definitions to
4941 %end-header. Don't use these declarations to separate pre-prologue
4942 blocks from post-prologue blocks. Add new order-independent
4943 declarations %before-header and %after-header as alternatives to the
4944 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
4945 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
4946 * NEWS (2.3+): Update for these changes.
4947 * data/glr.c (b4_before_definitions): Update to...
4948 (b4_start_header): ... this.
4949 (b4_after_definitions): Update to...
4950 (b4_end_header): ... this.
4951 * data/glr.cc: Likewise.
4952 * data/lalr1.cc: Likewise.
4953 * data/yacc.c: Likewise.
4954 * doc/bison.texinfo (The prologue): Update names, and replace remaining
4955 prologue blocks with %*-header declarations.
4956 (Calc++ Parser): Likewise.
4957 (Decl Summary): Update names.
4958 (Table of Symbols): Update description.
4959 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
4960 (PERCENT_END_HEADER): ... this.
4961 (PERCENT_BEFORE_DEFINITIONS): Update to...
4962 (PERCENT_START_HEADER): ... this.
4963 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
4964 (declaration): Update token names and m4 macro names.
4965 When parsing %end-header and %start-header, invoke translate_code
4966 before muscle_code_grow, and no longer set global booleans to remember
4967 whether these declarations have been seen.
4968 Parse new %after-header and %before-header.
4969 * src/reader.c (before_definitions, after_definitions): Remove.
4970 (prologue_augment): Accept a new bool argument to specify whether to
4971 augment the pre-prologue or post-prologue.
4972 * src/reader.h (before_definitions, after_definitions): Remove these
4974 (prologue_augment): Add new bool argument.
4975 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
4976 (PERCENT_END_HEADER): ... this.
4977 (PERCENT_BEFORE_DEFINITIONS): Update to...
4978 (PERCENT_START_HEADER): ... this.
4979 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
4980 * tests/actions.at (Printers and Destructors): Update names.
4982 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
4984 Add comparison operators for C++ location classes. Discussed at
4985 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
4986 * data/c++.m4 (b4_define_location_comparison): New boolean %define
4987 declaration indicating whether filename_type has an operator==. If
4988 filename_type is `std::string', it defaults to `1', `0' otherwise.
4989 * data/location.cc: Iff b4_define_location_comparison is `1', add
4990 operator== and operator!= for class position and for class location.
4993 * src/scan-action.l: Remove unused file.
4994 * src/symtab.c (symbol_printer_set): Use printer_location not
4995 destructor_location.
4996 * src/symtab.h (struct symbol): Replace incorrect source comment for
4998 * tests/input.at (Incompatible Aliases): Update output with correct
5001 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
5003 Don't put the pre-prologue in the header file. For the yacc.c code
5004 file and the glr.c header and code files, move the pre-prologue before
5005 the token definitions. Add new %before-definitions and
5006 %after-definitions to declare code that will go in both the header file
5007 and code file. Discussed at
5008 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
5009 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
5011 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
5012 * NEWS (2.3+): Describe these changes.
5013 * data/glr.c (b4_pre_prologue): Move from within to before...
5014 (b4_shared_declarations): ... this.
5015 Add new b4_before_definitions before b4_token_enums.
5016 Add new b4_after_definitions at the end.
5017 * data/glr.cc (b4_pre_prologue): Replace with...
5018 (b4_before_definitions): ... this in the header file.
5019 (b4_after_definitions): New near the end of the header file.
5020 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
5021 code file right before including the header file.
5022 (b4_before_definitions): New in the previous position of
5023 b4_pre_prologue in the header file.
5024 (b4_after_definitions): New near the end of the header file.
5025 * data/yacc.c: Clean up some m4 quoting especially in the header file.
5026 (b4_token_enums_defines): In the code file, move to right before
5027 YYSTYPE for consistency with the header file.
5028 (b4_before_definitions): New right before b4_token_enums_defines in
5029 both the header and code file.
5030 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
5031 header and code file.
5032 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
5033 of prologues for %union dependencies.
5034 (Decl Summary): In %defines description, mention the effect of
5035 %before-definitions and %after-definitions on the header file.
5036 (Calc++ Parser): Forward declare driver in a %before-definitions rather
5037 than in the pre-prologue so that make check succeeds.
5038 (Table of Symbols): Add entries for %before-definitions and
5040 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
5041 %before-definitions.
5042 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
5043 (declaration): Parse those declarations and append to
5044 b4_before_definitions and b4_after_definitions, respectively.
5045 * src/reader.c (before_definitions, after_definitions): New bools to
5046 track whether those declarations have been seen.
5047 (prologue_augment): Add to the post-prologue if %union,
5048 %before-definitions, or %after-definitions has been seen.
5049 * src/reader.h (before_definitions, after_definitions): New extern's.
5050 * src/scan-gram.l: Scan the new declarations.
5051 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
5052 prologue block in a %before-definitions or a %after-definitions based
5053 on whether the %union is declared.
5054 * tests/regression.at (Early token definitions with --yacc, Early token
5055 definitions without --yacc): Move tests for token definitions into the
5056 post-prologue since token names are no longer defined in the
5059 2006-06-20 Akim Demaille <akim@epita.fr>
5061 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
5062 (symbol_get): Use it.
5063 * src/parse-gram.y: Use it.
5065 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
5067 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
5068 build succeeds when configured with --enable-gcc-warnings.
5070 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5072 * src/parse-gram.y (char_name): New function.
5073 (CHAR, STRING, string_content): For %printer, properly escape.
5074 (ID): Prefer fputs to fprintf.
5075 (id): Reindent to be consistent with other rules.
5076 Properly quote char.
5078 The Translation Project changed its way of publishing translations
5079 to maintainers. I haven't received any responses to my request
5080 for supporting the old way, or for documenting the new way. I
5081 have modified 'bootstrap' to use screen scraping
5082 (in this case, HTML scraping). This is unreliable and inelegant,
5083 but I don't see any better way. Yuck.
5084 * bootstrap (TP_URL, WGET_COMMAND): New vars.
5085 (get_translations): New function, which uses HTML scraping to
5086 deduce locations of latest translations.
5087 Use this function to grab both bison and bison-runtime .po files.
5088 Don't bother priming the pump for the runtime-po domain any more,
5089 as it's now translated better than bison is.
5091 2006-06-19 Akim Demaille <akim@epita.fr>
5093 * src/scan-gram.l: No longer "parse" things after `%union' until
5094 `{'. Rather, return a single "%union" token.
5095 No longer make symbols: return strings, and leave the conversion
5096 to symbols to the parser.
5097 (SC_PRE_CODE, token_type): Remove.
5098 * src/parse-gram.y (%union): New field `character'.
5101 (ID, ID_COLON): Now that the scanner no longer makes them
5102 identifiers, adjust all uses to invoke symbol_get.
5103 (id_colon): New, wraps the conversion from string to symbol.
5104 (%union): Accept a possible union_name.
5105 (symbol): Now can be a char.
5106 * data/c.m4 (b4_union_name): Leave a default value.
5107 * data/glr.c, data/yacc.c: Use it.
5109 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
5111 For associating token numbers with token names for "yacc.c", don't use
5112 #define statements unless `--yacc' is specified; always use enum
5113 yytokentype. Most important discussions start at:
5114 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
5115 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
5117 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
5118 * NEWS (2.3+): Mention.
5119 * data/c.m4 (b4_yacc_if): New.
5120 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
5122 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
5123 on token name definitions.
5124 * src/getargs.c (usage): Capitalize `Yacc' in English.
5125 * src/output.c (prepare): Define b4_yacc_flag.
5126 * tests/regression.at (Early token definitions): Test that tokens names
5127 are defined before the pre-prologue not just before the post-prologue.
5128 Remove this test case and copy to...
5129 (Early token definitions with --yacc): ... this to test #define's.
5130 (Early token definitions without --yacc): ... and this to test enums.
5132 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
5134 * NEWS: Reword the post-2.3 change to not be so optimistic about
5135 removing the old "look-ahead" spelling.
5136 Update previous look-ahead/lookahead change reports.
5137 * REFERENCES: look-ahead -> lookahead (since that's
5138 what he actually wrote).
5139 * doc/refcard.tex: look ahead -> lookahead,
5140 look-ahead -> lookahead
5142 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
5144 For consistency, use `lookahead' instead of `look-ahead' or
5145 `look_ahead'. Discussed starting at

5215 2006-06-08 Joel E. Denny <jdenny@ces.clemson.edu>
5217 * src/flex-scanner.h (yytext): Remove stray `*/' in #define.
5219 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5221 * TODO: Add request from Nelson H. F. Beebe to be able to install
5222 Bison without installing the yacc script.
5224 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5226 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
5227 and yytext if they're already #define'd.
5228 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
5229 * src/scan-code-c.c: ... here.
5230 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
5233 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5235 Get Bison to build again when configured with --enable-gcc-warnings.
5236 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
5238 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
5239 loc argument as it shadows a global.
5240 * src/scan-gram.l: Remove stray comma that prevents boundary_set
5243 * src/.cvsignore: Add scan-code.c.
5245 2006-06-07 Akim Demaille <akim@epita.fr>
5247 * src/scan-gram.l: Move the "add a trailing ; to actions" code
5249 * src/scan-code.l: here.
5250 * tests/input.at (Torturing the Scanner): Fix another location
5253 2006-06-07 Akim Demaille <akim@epita.fr>
5255 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
5257 2006-06-06 Akim Demaille <akim@epita.fr>
5259 Extract the parsing of user actions from the grammar scanner.
5260 As a consequence, the relation between the grammar scanner and
5261 parser is much simpler. We can also split "composite tokens" back
5263 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
5264 * src/scan-gram.l (add_column_width, adjust_location): Move to and
5266 * src/location.h, src/location.c (add_column_width)
5267 (location_compute): these.
5268 Fix the column count: the initial column is 0.
5269 (location_print): Be robust to ending column being 0.
5270 * src/location.h (boundary_set): New.
5271 * src/main.c: Adjust to scanner_free being renamed as
5273 * src/output.c: Include scan-code.h.
5274 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
5276 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
5277 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
5278 which is now, again, a separate token.
5279 Adjust all dependencies.
5280 Whereever actions with $ and @ are used, use translate_code.
5281 (action): Remove this nonterminal which is now useless.
5282 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
5283 (grammar_current_rule_action_append): Use translate_code.
5284 (packgram): Bound check ruleno, itemno, and rule_length.
5285 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
5286 (last_string, last_braced_code_loc, max_left_semantic_context)
5287 (scanner_initialize, scanner_free, scanner_last_string_free)
5288 (gram_out, gram_lineno, YY_DECL_): Move to...
5289 * src/scan-gram.h: this new file.
5290 (YY_DECL): Rename as...
5292 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
5293 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
5294 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
5295 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
5296 Move these declarations, and...
5297 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
5299 * src/flex-scanner.h: this new file.
5300 * src/scan-gram.l (rule_length, rule_length_overflow)
5301 (increment_rule_length): Remove.
5302 (last_braced_code_loc): Rename as...
5303 (gram_last_braced_code_loc): this.
5304 Adjust to the changes of the parser.
5305 Move all the handling of $ and @ into...
5306 * src/scan-code.l: here.
5307 * src/scan-gram.l (handle_dollar, handle_at): Remove.
5308 (handle_action_dollar, handle_action_at): Move to...
5309 * src/scan-code.l: here.

5320 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5322 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5323 Use Akim's wording from
5324 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
5326 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5328 Between Bison releases, manually append `+' to the previous Bison
5329 release number, and use that as a signal to automatically print the
5330 ChangeLog's CVS Id keyword from --version. Discussed starting at
5331 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
5332 * ChangeLog: Add Id header.
5333 * configure.ac (AC_INIT): Append `+' to `2.3'.
5334 * src/.cvsignore: Add revision.c.
5335 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
5336 (BUILT_SOURCES): Add revision.c.
5337 (revision.c): New target rule. This file defines a new global variable
5338 named revision. It initializes it with either the Id from ChangeLog
5339 or, if VERSION doesn't contain `+', with the empty string.
5340 * src/getargs.c (version): Print the value of revision.
5341 * src/revision.h: Extern revision.
5343 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5345 * NEWS: Version 2.3.
5346 * configure.ac (AC_INIT): Likewise.
5348 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5350 * data/glr.c (YYRECOVERING): Define to be a function-like macro
5351 with no arguments, not as an object-like macro. This is for
5352 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
5353 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
5354 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
5357 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
5359 * src/getargs.c (usage): Back out yesterday's modification of the
5360 --help output so that we don't have to wait for translation before
5363 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5365 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
5366 Problem reported by Akim Demaille.
5368 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
5370 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5372 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5374 * data/yacc.c (yy_reduce_print): Omit trailing white space in
5375 generated source code. Problem reported by Frans Englich in
5376 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
5378 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
5380 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
5381 shell, not within 'make', so that 'make' by an ordinary builder
5382 (using GNU make) does not worry about configuring gzip. This also
5383 works around a bug reported independently by Keith Thompson and by
5384 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
5385 stderr rather than stdout, messing up the build logs.
5387 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5389 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
5390 to make sure that YYID will never be unused. This fixes a 'make
5391 maintainer-check' failure caused by the recent changes to the 'Trivial
5392 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
5394 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
5396 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5398 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
5399 state before an empty RHS is always resolved here. Only the location
5400 of that state is guaranteed to be resolved, and that's enough. This
5401 fixes the remaining bug reported by Derek M. Jones in
5402 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5403 * tests/glr-regression.at (Uninitialized location when reporting
5404 ambiguity): Test the above case.
5405 Also, the embedded comments in this test case claim it checks the case
5406 of an empty RHS that has inherited the initial location. However, the
5407 corresponding LHS was already resolved, so yyresolveLocations didn't
5408 actually have reason to modify it. Fix this by forcing
5409 nondeterministic operation at the beginning of the parse.
5411 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5413 * data/c.m4 (b4_yy_symbol_print_generate):
5414 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
5415 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
5416 of the bugs reported today by Derek M Jones in
5417 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5418 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
5419 defined to be a type name without parens or brackets.
5420 (Location Type): Similarly for YYLTYPE.
5421 * tests/regression.at (Trivial grammars): Put in a test for this
5422 bug that will be caught by 'make maintainer-check' (though not,
5423 alas, by 'make check' unless your compiler is picky).
5425 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5427 * NEWS: Version 2.2.
5428 * configure.ac (AC_INIT): Likewise.
5430 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
5432 * data/glr.c (yyreportTree): Make room in yystates for the state
5433 preceding the RHS. This fixes the segmentation fault reported by Derek
5435 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
5436 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
5437 to the user. Reported for yyreportTree by Derek M. Jones later in the

5440 Update my email address.
5441 Fix typo in Steve Murphy's name.
5443 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5445 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
5446 checking against YYLAST that caused the parser to miss a potential
5447 alternative in its diagnostic.
5448 Problem reported by Maria Jose Moron Fernandez in
5449 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
5450 * data/lalr1.cc (yysyntax_error_): Likewise.
5451 * data/yacc.c (yysyntax_error): Likewise.
5452 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
5453 tokens, in case we run into an older C compiler.
5454 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
5455 Use them to check for the off-by-one error fixed above.
5457 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
5458 YYSIZE_T, not size_t.
5459 * tests/regression.at (Trivial grammars): New test, to catch
5460 the error fixed by the above patch.
5462 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5464 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
5466 Reported by Steve Murphy.
5468 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5470 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
5471 * data/glr.cc: b4_location_flag is now b4_locations_flag.
5473 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5475 Implement --trace=m4.
5476 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
5477 * src/output.c (output_skeleton): When set, pass -dV to m4.
5479 Factor the handling of flags in m4.
5480 * src/output.c (prepare): Rename the muscle names debug, defines,
5481 error_verbose to debug_flag, defines_flag, error_verbose_flag.
5482 * data/c.m4: Adjust.
5483 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
5484 Use b4_define_flag_if to define other b4_FLAG_if macros.
5485 (b4_location_if): As a consequence, rename as...
5486 (b4_locations_if): this, for consistency.
5487 Adjust all the skeletons.
5489 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5491 * etc/bench.pm: Shorten bench names.
5493 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5495 * src/output.h, src/output.c (error_verbose): Move to...
5496 * src/getargs.h, src/getargs.c: here.
5498 Adjust dependencies.
5500 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5502 * data/c.m4 (b4_copyright): Put the special exception for Bison
5503 skeletons here, so we don't have to put it in each skeleton. All
5504 uses changed. Suggested by Akim Demaille. Also, wrap the
5505 copyright notice, in case it is longer than 80 columns. Replace
5506 comma by newline after title.
5508 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5510 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
5511 incompatibility, not a bug. Mention that it wasn't fixed as of
5514 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
5516 * examples/extexi: Enforce the precedence of concatenation over
5518 Reported by Tommy Nordgren.
5520 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
5522 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
5523 with the member "token".
5524 Reported by Martin Nylin.
5526 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
5528 * data/glr.c: Switch to Bison 2.2 special-exception language in
5529 the copyright notice. Use more-regular format for titles and
5531 * data/glr.cc: Likewise.
5532 * data/location.cc: Likewise.
5533 * data/yacc.cc: Likewise.
5534 * doc/bison.texinfo (Conditions): Document this.
5535 * NEWS: likewise. Upgrade version to 2.2.
5537 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
5539 * data/glr.cc: Remove dead code.
5541 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5543 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
5544 that variable and the line breaks the bootstrap. Problem reported
5545 by Juan M. Guerrero.
5547 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
5549 * doc/bison.texinfo (Multiple start-symbols): New.
5551 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
5553 * etc/README, etc/bench.pl: New.
5555 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
5557 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
5559 Reported by Mickael Labau.
5560 * tests/input.at (Torturing the Scanner): Test it.
5562 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
5564 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
5565 Problem reported by Bob Rossi.
5567 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
5569 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
5570 and didn't really work.
5571 For the index, use @ifnotinfo, not @iftex.
5572 Minor cleanups of spacing and terminology.
5574 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
5576 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
5577 of AT_NAME_PREFIX when %name-prefix is not used.
5579 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
5581 Apply --prefix to C++ skeletons too: they change the namespace.
5582 The test suite already exercize these cases.
5583 * data/c++.m4 (b4_namespace): New.
5584 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
5585 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
5586 * data/yacc.c, data/glr.c: Remove a useless `[]'.
5587 * doc/bison.texinfo: Document it.
5588 (Option Cross Key): Use @multitable in all formats. It looks
5589 nicer, even in TeX outputs.
5590 (Rules): Use the same code whatever the output type is.
5591 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
5592 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
5593 * tests/calc.at: Use it, instead of hard coding `yy'.
5595 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
5597 * TODO: Remove dead items.
5599 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
5601 * doc/FAQ: Remove, merged into...
5602 * doc/bison.texinfo (FAQ): this.
5603 * doc/Makefile.am (EXTRA_DIST): Adjust.
5605 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
5607 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
5609 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
5610 * doc/bison.texinfo (Calc++ Scanner): Use it.
5612 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
5614 Fix two nits reported by twlevo, plus one more that I discovered.
5616 * src/assoc.h (assoc_to_string): Give a name to the arg, as
5617 this is the usual Bison style.
5618 * src/location.h (location_print): Likewise.
5620 * src/reader.h (token_name): Likewise.
5622 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
5624 Fix some nits reported by twlevo.
5625 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
5626 and "POSIX". Use more-modern syntax for URLs. Mention C++
5627 and ask for Java. Don't hardwire OS version numbers. Add
5629 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
5630 * src/conflicts.c (solved_conflicts_obstack): Now static.
5632 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
5634 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
5635 page. Say "you can use it" not "you may use it" as on the web page;
5636 we're describing capabilities not granting permission.
5638 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
5640 * data/glr.c (yyresolveLocations): Rename local variables to avoid
5641 shadowing warnings. Use usual patter for iterating through RHS.
5642 * tests/glr-regression.at
5643 (Uninitialized location when reporting ambiguity):
5644 Modify yylex so that it uses its argument, rather than trying
5645 to rely on ARGSUSED (which doesn't work for gcc with warnings).
5646 const char -> char const.
5648 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
5649 Don't use tabs inside commands; it messes up 'ps'.
5650 Problem reported by twlevo.
5652 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
5654 * tests/glr-regression.at (Uninitialized location when reporting
5655 ambiguity): New test case.
5656 * data/glr.c (yyresolveLocations): New function, which uses
5658 (yyresolveValue): Invoke yyresolveLocations before reporting an
5660 * doc/bison.texinfo (Default Action for Locations): Note
5661 YYLLOC_DEFAULT's usage for ambiguity locations.
5662 (GLR Semantic Actions): Cross-reference those notes.
5664 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
5666 * tests/glr-regression.at (Leaked semantic values when reporting
5667 ambiguity): Remove unnecessary union and type declarations.
5668 (Leaked lookahead after nondeterministic parse syntax error): New test
5670 * data/glr.c (yyparse): Check for zero stacks remaining before
5671 attempting to shift the lookahead so that you don't lose it.
5673 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5675 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
5676 * tests/glr-regression.at (Leaked semantic values when reporting
5677 ambiguity): New test case.
5678 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
5679 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
5680 now unnecessary yystackp parameter.
5681 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
5682 destructors can be called.
5684 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
5685 in existing testcases.
5687 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5689 Don't leak semantic values for parent RHS when a user action cuts the
5690 parser, and clean up related code a bit.
5691 * tests/glr-regression.at (Leaked merged semantic value if user action
5692 cuts parse): Rename to...
5693 (Leaked semantic values if user action cuts parse): ... this. Add check
5694 for leaked parent RHS values.
5695 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
5696 between an unresolved state (non-empty chain of semantic options) and
5697 an incomplete one (signaled by an empty chain).
5698 (yyresolveStates): Document the interface. Move all manipulation of a
5699 successfully or unsuccessfully resolved yyGLRState to...
5700 (yyresolveValue): ... here so that yyresolveValue always leaves a
5701 yyGLRState with consistent data and thus is easier to understand.
5702 Remove the yyvalp and yylocp parameters since they are always just
5703 taken from the yys parameter. When reporting a discarded merged value
5704 in debugging output, note that it is incompletely merged. Document the
5706 (yyresolveAction): If resolving any of the RHS states fails, destroy
5707 them all rather than leaking them. Thus, as long as user actions are
5708 written to clean up the RHS correctly, yyresolveAction always cleans up
5709 the RHS of a semantic option. Document the interface.
5711 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
5713 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
5714 led to a segmentation fault in GNU Pascal. Problem reported
5717 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
5719 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
5720 mid-rule action inside a nonterminal symbol in order to declare a
5721 destructor for its semantic value.
5723 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>

5727 __cplusplus && ! defined _STDLIB_H && !
5728 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
5729 defined free))]: Include <stdlib.h> rather than rolling our own
5730 declarations of malloc and free, to avoid problems with
5731 incompatible declarations (using 'throw') C++'s stdlib.h. This
5732 should fix Debian bug 340012

5744 * NEWS: Version 2.1a.
5745 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
5746 since C99 requires this.
5748 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
5750 * m4/c-working.m4: New file.

5763 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
5764 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this

5773 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
5775 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
5776 nodist_PROGRAMS, since we don't need to actually compile the
5777 example if we're just doing a plain 'make'. This avoids bothering
5778 the installer unnecessarily about problems due to weird C++

5783 More portability fixes for problems summarized by Nelson H. F. Beebe.
5785 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
5786 than #include "...", and compile with -I'.'. The old method was
5787 not portable, according to Posix and the C standard, and it does
5788 not work with Sun C 5.7, where previous #line directives affect
5789 the working directory used in later #include "..." directives.

5800 '#include <map>' works and that you can apply ++ to iterators.
5802 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
5804 Work around portability problems summarized by Nelson H. F. Beebe in

5808 that '#include <string>' works.
5810 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
5811 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
5812 "warning: sorry: semantics of inline function static data `const
5813 unsigned char translate_table[262]' are wrong (you'll wind up with
5816 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
5817 or, xor to not_, and_, or_, and xor_, respectively. This works
5818 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
5819 random system header somewhere that includes the equivalent of

5828 During deterministic GLR operation, user actions should be able to
5829 influence the parse by changing yychar. To make this easier to fix and
5830 to make glr.c easier to evolve in general, don't maintain yytoken in
5831 parallel with yychar; just compute yytoken when needed.
5832 * tests/glr-regression.at (Incorrect lookahead during deterministic
5833 GLR): Check that setting yychar in a user action has the intended

5836 (yyclearin): Don't set *yytokenp.
5837 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
5838 yychar rather than *yytokenp to determine the current lookahead.
5839 Compute yytoken locally when needed.
5840 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
5843 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
5844 after `--report' documentation.

5858 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
5859 got from <http://bro-ids.org/download.html>. The bug is that
5860 when two actions appeared in succession, the second one was
5861 scanned before the first one was added to the grammar rule
5862 as a midrule action. Bison then output the incorrect warning
5863 "parse.y:905.17-906.36: warning: unused value: $3".
5864 * src/parse-gram.y (BRACED_CODE, action): These are no longer
5865 associated with a value.
5866 (rhs): Don't invoke grammar_current_rule_action_append.
5867 (action): Invoke it here instead.
5868 * src/reader.c (grammar_midrule_action): Now extern.
5869 (grammar_current_rule_action_append): Don't invoke
5870 grammar_midrule_action; that is now the scanner's job.
5871 * src/reader.h (last_string, last_braced_code_loc):
5872 (grammar_midrule_action): New decls.
5873 * src/scan-gram.l (last_string): Now extern, sigh.
5874 (last_braced_code_loc): New extern variable.
5875 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
5876 rule already has an action.
5877 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
5878 * tests/input.at (AT_CHECK_UNUSED_VALUES):
5879 Add some tests to check that the above changes fixed the bug.
5881 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
5883 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
5884 All used changed. Check whether the symbol has a destructor,
5885 not whether it is typed.
5886 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
5887 that the values are still reported as unused. All line numbers

5904 user can override the types.
5905 (short): #undef, to work around a bug in Pike 7.0.
5906 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
5907 (union yyalloc.yyss): Use yytype_int16 rather than short.
5909 (yysigned_char): Remove.
5910 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
5911 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.

6125 in the yychar entry.
6126 In the yychar entry, remove mention of the local yychar case (pure
6127 parser) since this is irrelevant information when writing semantic
6128 actions and since it's already discussed in `Table of Symbols' where
6129 yychar is otherwise described as an external variable.
6130 In the yychar entry, don't call it the `current' look-ahead since it
6131 isn't when semantic actions are deferred.
6132 In the yychar and yyclearin entries, add note about deferred semantic
6134 Add yylloc and yylval entries discussing look-ahead usage.
6135 (Look-Ahead Tokens): When discussing yychar, don't call it the

6156 appropriately during nondeterministic operation.
6157 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
6158 members to store the current lookahead to be used by the deferred
6160 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
6161 from which the RHS is taken. Set the lookahead members of the new
6162 yySemanticOption according to the lookahead status for stack yyk.

6164 yyaddDeferredAction.
6165 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

6176 (Incorrect lookahead during nondeterministic GLR): New test case.
6178 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

6190 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
6192 * data/glr.c (yyresolveValue): When merging semantic options, if at
6193 least one user action succeeds but a later one cuts the parse, then
6194 destroy the semantic value before returning rather than leaking it.
6195 (yyresolveStates): If a user action cuts the parse and thus
6196 yyresolveValue fails, ignore the (unset) semantic value rather than
6197 corrupting the yyGLRState, and empty the semantic options list since
6198 the user actions should have called all necessary destructors.
6199 Simplify code with YYCHK.
6200 * tests/glr-regression.at (Corrupted semantic options if user action
6201 cuts parse): New test case.
6202 (Undesirable destructors if user action cuts parse): New test case.

6423 * tests/cxx-type.at: Construct a tree, count the parents of shared
6424 nodes, and free each node once and only once. Previously, the memory
6425 for semantic values was leaked instead.
6427 2005-12-21 Joel E. Denny <address@hidden>
6429 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.

6431 yystackp->yyloc similar to yychar and yynerrs.

6449 destroy the RHS symbols of a rule.
6450 * data/yacc.c (yylen): Initialize to 0.

6468 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
6469 * djgpp/config.sed: Replace every occurence of the file name
6470 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

6500 sed out the final state number.
6502 Work around portability problem on Solaris 10: flex-generated
6503 files include <stdio.h> before <config.h>, which messes up
6504 because the latter defines __EXTENSIONS__. Address the problem
6505 by creating two new little files that include <config.h> first,
6506 then include the flex-generated files. Rewrite everyone else
6507 to include <config.h> first, as well.
6508 * lib/timevar.c: Always include "config.h".

6554 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
6555 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
6556 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
6558 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.

6584 it's no longer just a file.
6585 * data/glr.c: Grant a special exception for C GLR parsers, that
6586 reads like the already-existing exception for C LALR(1) parsers.

6588 * data/lalr1.cc: Likewise.

6864 (user_actions_output): Break apart two printfs.
6865 * src/parse-gram.y (%printer): Prefer printf to putc and puts.

6868 * src/system.h: Include unlocked-io.h rathe than stdio.h.
6870 * data/glr.c (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
6871 Use assignments rather than casts-to-void to suppress
6872 unused-variable warnings. This pacifies 'lint'.
6873 * data/lalr1.cc (yysymprint_, yydestruct_): Use a call to suppress
6874 unused-variable warnings.
6876 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>
6878 * Makefile.am: DJGPP specific files added to EXTRA_DIST.
6880 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
6882 Use unlocked I/O for a minor performance improvement on hosts like
6883 GNU/Linux and Solaris that support unlocked I/O. The basic idea
6884 is to use the gnlib unlocked-io module, and to prefer putc and
6885 puts to printf when either will work (since the latter doesn't
6886 come in an unlocked flavor).
6887 * bootstrap (gnulib_modules): Add unlocked-io.
6888 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
6889 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.

6901 * src/output.c (escaped_output): Likewise.
6902 (user_actions_output): Coalesce two printfs.
6903 * src/parse-gram.y (%printer): Prefer putc and puts to printf.
6904 * src/reduce.c (reduce_print): Likewise.
6905 * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
6906 * src/system.h: Include unlocked-io.h rather than stdio.h.
6908 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
6909 this confuses xgettext.

6929 Akim Demaille <akim@epita.fr>
6931 Make sure -odir/foo.cc creates dir/location.hh etc.
6932 * src/files.h (spec_outfile, parser_file_name, spec_name_prefix)

6951 2005-10-02 Juan Manuel Guerrero <juan.guerrero@gmx.de>
6953 * lib/subpipe.c: New function end_of_output_subpipe() added
6954 to allow support for non-posix systems. This is a no-op function
6957 * lib/subpipe.h: New function end_of_output_subpipe() added
6958 to allow support for non-posix systems. This is a no-op function
6961 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
6962 handle the lack of pipe/fork functionality on non-posix systems.
6964 * djgpp/Makefile.maint: DJGPP specific file.
6966 * djgpp/README.in: DJGPP specific file.
6968 * djgpp/config.bat: DJGPP specific configuration file.
6970 * djgpp/config.sed: DJGPP specific configuration file.

6983 * data/lalr1.cc: here.
6984 (location.hh): Include it after the user prologue, in case the
6985 filename type is defined by the user.
6986 Forward declation location and position before the pre-prologue.
6987 (yyresult_): Rename as...
6988 (yyresult): this, it's a local variable, not an attribute.
6989 * data/Makefile.am (dist_pkgdata_DATA): Adjust.
6991 2005-10-01 Akim Demaille <akim@epita.fr>
6993 * examples/extexi: Restore the #line generation.

6996 Alexandre Duret-Lutz <adl@gnu.org>
6998 Move the token type and YYSTYPE in the parser class.
6999 * data/lalr1.cc (stack.hh, location.hh): Include earlier.
7000 (parser::token): New, from the moved free definition of tokens.
7001 (parser::semantic_value): Now a full definition instead of an
7002 indirection to YYSTYPE.
7003 (b4_post_prologue): No longer included in the header file, but
7004 in the implementation file.
7005 * doc/bison.texi (C+ Language Interface): Update.
7006 * src/parse-gram.y: Support unary %define.
7007 * tests/actions.at: Define global_tokens_and_yystype for backward

7046 local variables whose names begin with 'yy'.
7047 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
7048 Trivial changes from Joel E. Denny.
7050 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
7052 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
7053 don't use alloca any more.
7055 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
7056 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
7057 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
7058 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
7059 to match yacc.c, to test more hosts.
7061 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
7063 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
7064 doesn't affect behavior.
7065 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
7067 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
7068 This works a bit better with glibc, if user code has already included
7070 * doc/bison.texinfo (Bison Parser): Document that users can't
7071 arbitrarily use malloc and free for other purposes. Document
7072 that <alloca.h> and <malloc.h> might be included.

7085 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
7086 (YYSTACK_ALLOC_MAXIMUM): Use it.
7087 (yysyntax_error): New function.
7088 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
7089 multiple syntax errors are reported, and alloca is being used.
7090 Instead, reallocate buffers twice as big each time, so that
7091 we waste at most half the allocated memory. Start with a small
7092 (128-byte) buffer that will suffice in most cases anyway.
7093 Use yysyntax_error to do most of the work.
7095 * doc/bison.texinfo (Error Reporting, Table of Symbols):
7096 yynerrs is the number of errors reported, not the number of
7099 * tests/glr-regression.at (Duplicated user destructor for lookahead):
7100 Mark it as expected to fail.
7101 Cast result of malloc; problem reported by twlevo@xs4all.nl.
7102 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
7103 Don't start user-code symbols with "yy", to avoid name space problems.
7105 2005-09-19 Akim Demaille <akim@epita.fr>
7107 Remove the traits, failed experiment.
7108 It never proved useful, and anyway because of the current
7109 definition, it was not possible to have several specialization of
7110 this traits, making it useless.
7111 * data/lalr1.cc (yy:traits): Remove.
7112 Inline its definitions in the parser class.
7114 2005-09-19 Akim Demaille <akim@epita.fr>

7136 * src/output.c (prepare): Likewise.
7137 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
7138 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
7139 is not defined. This is an awful hack, but it's enough for now.
7140 All callers changed.
7141 * tests/glr-regression-at (make_value): Args are const pointers now,
7142 to avoid GCC warning.
7143 (Duplicated user destructor for lookahead): New test. Currently
7144 skipped. It fails on my host but I'm not sure it'll always fail.
7146 2005-09-16 Akim Demaille <akim@epita.fr>
7148 * src/symtab.h (struct symbol): Declare the printer and destructor
7149 as const, to avoid accidental calls to free.
7150 (symbol_destructor_set, symbol_printer_set): Adjust.
7151 * src/symtab.c: Adjust.
7153 2005-09-16 Akim Demaille <akim@epita.fr>
7155 * data/c.m4 (b4_token_enums): New.
7156 (b4_token_defines): Rename as...
7157 (b4_token_enums_defines): this.
7158 (b4_token_defines): New, output only the #defines.
7159 * data/yacc.c, data/glr.c: Adjust.
7160 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
7161 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
7164 2005-09-16 Akim Demaille <akim@epita.fr>
7166 * data/lalr1.cc (yylex_): Remove, inline its code.
7167 (yyreport_syntax_error_): Remove, replaced by...
7168 (yysyntax_error_): this which returns a string and leaves to the
7169 caller the call to the users' error function.
7170 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
7171 Move from members of the parser object...
7172 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
7173 to local variables of the parse function.
7175 2005-09-16 Akim Demaille <akim@epita.fr>
7177 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
7178 since it's in Bison's name space.
7180 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
7182 * data/glr.c (yyresolveValue): Add default case to pacify
7183 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
7185 * NEWS: Document when yyparse started to return 2.
7186 * doc/bison.texinfo (Parser Function): Document when yyparse
7189 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
7190 (b4_filename_type): Renamed back from b4_file_name_type. All uses
7192 (class position): file_name -> filename (reverting). All uses changed.
7194 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
7196 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
7197 do anything if $@ exists. This reverts part of the 2005-07-07
7200 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
7202 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
7203 contains obsolete information and isn't worth distributing as a
7204 separate file anyway.
7205 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
7206 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
7207 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
7208 (yyparse): Abort if user code uses longjmp to throw an unexpected
7211 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
7213 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
7214 Suggested by twlevo@xs4all.nl.
7216 * data/glr.c (YYCHK1): Do not assume YYE is in range.
7217 This avoids a diagnostic from gcc -Wswitch-enum.
7218 Problem reported by twlevo@xs4all.nl.
7220 * doc/bison.texinfo: Don't use "filename", as per GNU coding
7221 standards. Use "file name" or "file" or "name", depending on
7223 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
7224 not to hack/foo.tab.c.
7225 (Calc++ Top Level): 2nd arg of main is not const.
7226 * data/glr.c: b4_filename -> b4_file_name.
7227 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

7240 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
7241 to accommodate latest gnulib.
7243 * tests/glr-regression.at (Duplicate representation of merged trees):
7244 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
7246 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
7249 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7251 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
7252 All uses changed. Invoke user destructor after an error during a
7253 split parse (trivial change from Joel E. Denny).
7255 * tests/glr-regression.at
7256 (User destructor after an error during a split parse): New test case.
7257 Problem reported by Joel E. Denny in:
7258 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
7260 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7262 * README-cvs: Give URLs for recommended tools.
7263 Mention Gzip version problem, and bootstrapping issues.
7264 Remove troubleshooting section, as it's somewhat obsolete.
7266 * bootstrap (no_cache): New var, to accommodate different wget
7267 variants. Use it instead of '-C off'. Problem reported by
7270 * data/glr.c (yydestroyStackItem): New function.
7271 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
7272 debugging information. Problem reported by Joel E. Denny.
7274 2005-08-25 Akim Demaille <akim@epita.fr>
7276 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
7278 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
7280 * data/glr.c (yyrecoverSyntaxError, yyreturn):
7281 Don't invoke destructor on unresolved entries.
7282 * tests/glr-regression.at
7283 (User destructor for unresolved GLR semantic value): New test case.
7284 Problem reported by Joel E. Denny in:
7285 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
7287 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
7289 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
7291 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
7292 lib-prefix.m4, po.m4.
7294 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
7295 in yydestruct diagnostic, since it might not be an error.
7296 Problem reported by Joel Denny near end of
7297 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
7298 * data/lalr1.cc (yyerturn): Likewise.
7299 * data/yacc.c (yyreturn): Likewise.
7300 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
7302 * src/files.c: Remove obsolete FIXME comment.
7304 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
7305 with the other templates, and to fix bogus run-on messages such
7306 as the one reported at the end of
7307 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
7308 All callers changed to avoid the newline.
7309 (yyprocessOneStack): Output two lines rather than one, to accommodate
7310 the above change. This changes the debug output format slightly.
7312 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
7313 reported by Joel E. Denny in
7314 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
7316 * tests/glr-regression.at (Duplicate representation of merged trees):
7317 New test, from Joel E. Denny in:
7318 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
7319 * THANKS: Add Joel E. Denny.
7321 * configure.ac (AC_INIT): Bump to 2.0c.
7323 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
7325 * NEWS: Version 2.0b.
7327 * Makefile.am (SUBDIRS): Put examples before tests, so that
7328 "make check" doesn't finish with "All 1 tests passed".
7330 * tests/regression.at (Token definitions): Don't rely on
7331 AT_PARSER_CHECK for data that contains backslashes. It currently
7332 uses 'echo', and 'echo' isn't portable if its argument contains
7333 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
7334 that the byte '\0xff' is not printable in the C locale; it is,
7335 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
7336 not printable, so use '\0x81' to test.
7338 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
7339 version of GCC, since the macro is used with non-GCC compilers.
7341 Fix core dump reported by Pablo De Napoli in
7342 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.

7344 * src/parse-gram.y (token_name): Translate type before using
7347 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
7348 the user's name space. All uses changed to __attribute__
7350 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
7351 Add __attribute__ ((__noreturn__)).
7353 * etc/clcommit: Remove. We weren't using it, and it failed
7354 "make maintainer-distcheck".
7355 * Makefile.maint: Merge from coreutils.
7356 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
7357 (syntax-check-rules): Change list of rules as described below.

7374 (signatures, %.asc): Remove.
7375 (rel-files, announcement): Remove signatures.
7376 Restore old updating code, even though we don't use it, so
7377 that we're the same as coreutils.
7378 (alpha, beta, major): Depend on news-date-check.
7379 Make the upload commands.
7381 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
7382 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
7383 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.

7388 * tests/sets.at: Likewise.
7390 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
7391 we comment out the Autoconf version number.
7392 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
7393 it's error-prone and "make maintainer-distcheck" rejects it.
7395 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
7396 Indent calls to "error" to pacify "make maintainer-distcheck",
7397 when the calls are not intended to be translated.

7402 (bison_SOURCES): Add scan-skel.h.
7403 (sc_tight_scope): New rule, from coreutils.
7405 * src/files.c (src_extension, header_extension):
7406 Now static, not extern.
7407 * src/getargs.c (short_options): Likewise.
7408 * src/muscle_tab.c (muscle_table): Likewise.
7409 * src/parse-gram.y (current_class, current_type, current_prec):
7411 * src/reader.c (grammar_end, previous_rule_end): Likewise.
7412 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
7413 * src/main.c (main): Cast bindtextdomain and textdomain calls to
7414 void, to avoid warning when NLS is disabled.
7415 * src/output.c: Include scan-skel.h.
7416 (scan_skel): Remove decl, since scan-skel.h does this.
7418 Indent calls to "error" to pacify "make maintainer-distcheck".
7419 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
7420 * src/reader.h (gram_end, gram_lineno): New decls to pacify
7421 "make maintainer-distcheck".
7422 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
7423 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
7424 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):

7426 * src/scan-skel.h: New file.
7427 * src/uniqstr.c (uniqstr_assert):
7428 Indent calls to "error" to pacify "make maintainer-distcheck".
7430 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
7433 * tests/torture.at: Revamp to avoid misuse of atoi that
7434 "make maintainer-distcheck" complained about.
7436 * examples/extexi (message): Don't print a message more than once,
7437 and omit line-number decoration that makes Emacs compile think
7438 that informative messages are worth worrying about.
7440 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
7442 * configure.ac: Update version number.
7444 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
7446 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
7447 autogenerated by the maintainer.
7448 * examples/calc++/.cvsignore: Add *.yy.
7450 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
7451 * lib/bitset_stats.c (bitset_stats_init): Likewise.
7452 * lib/bitsetv.c (bitsetv_alloc): Likewise.
7454 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
7456 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
7457 from maintainer-distcheck about casting the argument of 'free'.
7459 * NEWS: Mention recent yytname changes.
7460 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
7462 * bootstrap: For translations that have not yet been upgraded to
7463 the new runtime-po domain, prime the pump by extracting the
7464 relevant strings from the obsolete translations. This code can be
7465 removed once the bison-runtime domain has been translated by each
7468 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
7469 now that token names are already quoted.
7471 Fix problem reported by Anthony Heading.
7472 * data/glr.c (YYTOKEN_TABLE): New macro.
7473 (yytname): Define if YYTOKEN_TABLE.
7474 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
7475 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
7476 (YYERROR_VERBOSE): Define the same way the other skeletons do.
7477 * src/output.c (prepare_symbols): Output token_table_flag.
7479 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
7481 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
7482 again if the first call fails.
7484 * data/glr.c (yytnamerr): New function.
7485 (yyreportSyntaxError): Use it to dequote most string literals.
7486 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
7487 with other skeletons. All uses changed.
7488 (yytnameerr_): New function.
7489 (yyreport_syntax_error): Use it to dequote most string literals.
7490 * data/yacc.c (yytnamerr): New function.
7491 (yyerrlab): Use it to decode most string literals.
7492 * doc/bison.texinfo (Decl Summary, Calling Convention):
7493 Clarify quoting convention of yytname.
7494 * src/output.c (prepare_symbols): Quote all names. This undoes
7495 the 2005-04-17 change, which is now accomplished (mostly) via
7496 changes in the parsers as described above.
7497 * tests/regression.at (Token definitions, Web2c Actions):
7498 Undo most 2005-04-17 change here, too.
7500 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
7502 Fix more problems reported by twlevo@xs4all.nl.
7503 * tests/cxx-type.at: Don't pipe output of ./types through sed to
7504 remove trailing spaces. This loses the exit status of ./types,
7505 and isn't needed since ./types shouldn't be emitting trailing
7507 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
7508 as the stack isn't valid in that case.
7510 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
7511 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
7512 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
7513 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
7515 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
7516 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
7517 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
7520 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
7521 overly-picky compilers that reject 'char *foo = "bar";'.
7523 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
7524 to FILE * parameter, not to stderr. This fixes a typo introduced
7525 in the 2005-07-12 change.
7527 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
7528 warnings from GCC 4.
7530 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
7531 (yyglrShiftDefer, yysplitStack):
7532 Remove unused parameters b4_pure_formals. All uses changed.
7533 (yyglrShift): Remove unused parameters b4_user_formals.
7535 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
7537 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
7539 Destructor cleanups and regularization among the three skeletons.
7540 * NEWS: Document the behavior changes.
7541 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
7542 stack before failing, as the cleanup code will do it for us now.
7543 * data/lalr1.cc (yyerrlab): Likewise.
7544 * data/glr.c (yyparse): Pop everything off the stack before
7545 freeing it, so that destructors get called properly.
7546 * data/lalr1.cc (yyreturn): Likewise.
7547 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
7548 This is more consistent.
7549 * doc/bison.texinfo (Destructor Decl): Mention more reasons
7550 why destructors might be called. 1.875 -> 2.1.
7551 (Destructor Decl, Decl Summary, Table of Symbols):
7552 Some English-language cleanups for %destructor.
7553 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
7554 Add output line for destructor of start symbol.
7555 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
7556 because of that same extra output line.
7558 * NEWS: Document minor wording changes in diagnostics of
7559 Bison-generated parsers.
7560 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
7561 Remove unused formals. All uses changed.
7562 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
7563 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
7564 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
7565 Rename yyoverflowab to yyexhaustedlab.
7566 When memory exhaustion occurs during syntax-error reporting,
7567 report it separately rather than in a single diagnostic; this
7569 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
7570 (Memory Exhausted): Renamed from Parser Stack Overflow.
7571 Revamp wording slightly to prefer "memory exhaustion".
7572 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
7574 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
7576 Add i18n support to the GLR skeleton. Partially fix the C++
7577 skeleton; a C++ expert needs to finish this. Remove debugging
7578 msgids; there's little point to having them translated, since they
7579 can be understood only by someone who can read the
7580 (English-language) source code.
7582 Generate runtime-po/bison-runtime.pot automatically, so that we
7583 don't have to worry about garbage getting in that file. We'll
7584 make sure after the next official release that old msgids don't
7586 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
7588 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
7590 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
7591 Fix typos in explanations of the runtime file.
7592 * bootstrap: Change gettext keyword from YYI18N to YY_.
7593 Use standard Makefile.in.in in runtime-po, since we'll arrange
7594 for backward-compatible bison-runtime.po files in a different way.
7595 * data/glr.c (YY_): New macro, from yacc.c.
7596 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
7597 Translate messages intended for users.
7598 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
7599 the wording in the other skeletons. We don't know that the memory
7601 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
7602 Use same method that yacc.c uses.
7603 Don't translate debugging messages.
7604 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
7605 it doesn't work (yet), and requires C++ expertise to fix.
7606 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
7607 Move defn to a more logical place, to be consistent with other
7609 Don't translate debugging messages.
7610 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
7611 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
7612 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
7613 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
7615 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
7616 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
7618 * tests/glr-regression.at (Badly Collapsed GLR States):
7620 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
7621 yylex should return 0 at EOF rather than aborting.
7623 Improve tests for stack overflow in GLR parser.
7624 Problem reported by twlevo@xs4all.nl.
7625 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
7627 (yyStackOverflow): Just longjmp, but with value 2 so that caller
7628 can handle the problem.
7629 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
7630 (yyparse): New local variable yyresult to record the result.
7631 Use result of setjmp to set it, rather than storing itinto
7633 (yyDone): Remove label.
7634 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
7635 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
7636 if YYABORT is used).
7637 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
7638 yyparse status; put status > 1 into diagnostic.
7639 Check that status==2 works.
7640 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
7641 Use exit status 3 for failure to open (which shouldn't happen).
7643 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
7645 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
7646 1 on syntax error; just let yyparse do its thing.
7647 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
7648 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
7649 (Exploding the Stack Size with Alloca):
7650 (Exploding the Stack Size with Malloc):
7651 Expect exit status 2, not 1, since the parser is supposed to blow
7652 its stack. Problem reported by twlevo@xs4all.nl.
7654 * data/glr.c (yyparse): Don't assume that the initial calls
7655 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
7656 Print a stack-overflow message and fail instead.
7657 Initialize the line-number information before creating the stack,
7658 so that the stack-overflow message can report line zero safely.
7660 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
7662 Fix problems reported by twlevo@xs4all.nl.
7663 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
7664 (yyuserMerge): Provide a default case if b4_mergers is empty.
7665 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
7666 * tests/glr-regression.at
7667 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
7668 Add casts to pacify C++ compilers.
7669 * tests/glr-regression.at (Improper merging of GLR delayed action
7670 sets): Declare yylex before using it.
7671 * tests/Makefile.am (maintainer-check-g++): Fix a stray
7672 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
7673 test for valgrind; valgrind is independent of g++.
7674 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
7675 for compatibility with POSIX 1003.1-2001 (if running coreutils).
7676 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
7677 Use a destructor, so that we can expand the stack. Change
7678 YYSTYPE to char * so that we can free it. Cast result of malloc.
7680 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
7682 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
7683 a valgrind failure. Problem reported by twlevo@xs4all.nl.
7685 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
7687 * PACKAGING: New file, suggested by Bruno Haible and taken from
7688 similar wording in gettext's PACKAGING file.
7689 * NEWS: Mention PACKAGING.

7694 * NEWS: Document recent i18n improvements.
7695 * bootstrap: Get runtime translations into runtime-po.
7696 Create runtime-po files automatically, if possible.
7697 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
7698 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
7699 does not infringe on the user's name space.
7700 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
7701 * doc/bison.texinfo (Internationalization): Revamp the English
7702 and Texinfo syntax a bit, to try to make it clearer.
7703 (Bison Options, Option Cross Key): Mention --print-localedir.
7704 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
7705 YYENABLE_NLS. Quote a bit more.

7715 * runtime-po/Makevars: Likewise.
7716 * runtime-po/LINGUAS: Likewise.
7717 * runtime-po/de.po: Likewise; we will rely on the translation project
7718 to maintain this, so "bootstrap" should get it.
7719 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
7721 * src/main.c (main): Bind the bison-runtime domain, too.
7723 2005-07-12 Bruno Haible <bruno@clisp.org>
7725 * data/yacc.c: Include <libintl.h> when NLS is enabled.
7726 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
7727 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
7728 * runtime-po: New directory.
7729 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
7730 $(DOMAIN).pot-update rule, so that old messages are never dropped.
7731 * runtime-po/Rules-quot: New file, copied from po/.
7732 * runtime-po/quot.sed: Likewise.
7733 * runtime-po/boldquot.sed: Likewise.

7753 (Internationalization): New section.
7755 2005-07-12 Akim Demaille <akim@epita.fr>
7757 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
7758 for consistency with the rest of the code.

7775 b4_at_dollar and b4_dollar_dollar.
7777 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
7779 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
7780 and Pennello's paper.
7782 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
7784 * data/yacc.c (yyparse): Undo previous patch. Instead,
7785 set yylsp[0] and yyvsp[0] only if the initial action
7786 sets yylloc and yylval, respectively.
7788 * data/yacc.c (yyparse): In the initial action, set
7789 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
7790 This avoids the use of undefined variables if the initial
7791 action does not set yylloc and/or yylval.
7793 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7795 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
7796 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
7797 Remove from CVS. These files are automatically generated.
7798 * examples/extexi: Clarify that this file is now part of Bison,
7799 not GNU M4, and that it works with any POSIX-compatible Awk.
7800 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
7801 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
7802 so that we also get calc++-parser.yy. Geneate it.
7803 Use $(AWK), not gawk, since any conforming Awk will do.
7804 Put comment before action, since older 'make' can't handle comment
7806 $(BUILT_SOURCES): List all built sources, not just some of them.
7807 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
7808 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
7809 $($(calc_sources_generated)): Remove unnecessary test for existence
7810 of target. (This had a shell syntax error anyway; a stray "x".)
7811 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
7813 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
7815 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
7816 implied by the other modules.
7818 2005-07-06 Akim Demaille <akim@epita.fr>
7820 Bind examples/calc++ to the package.
7821 * examples/calc++/Makefile: Remove, replaced by...
7822 * examples/calc++/Makefile.am: ... this new file.
7823 * examples/calc++/test: Remove input.
7824 * examples/calc++/compile: Remove.
7825 * examples/Makefile.am: New.
7826 * configure.ac, Makefile.am: Adjust.
7827 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
7829 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
7831 * data/glr.c (yyFail): Drastically simplify; since the format argument
7832 never had any % directives, we can simply pass it to yyerror.
7833 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
7834 be modified later, as that is the usual style in glr.c.
7835 Problems reported by Paul Hilfinger.
7837 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
7838 and size overflow errors.
7839 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
7840 in case the user prolog sets feature-test macros like _GNU_SOURCE.
7841 (YYSIZEMAX): New macro.
7842 (yystpcpy): New function, taken from yacc.c.
7843 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
7844 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
7845 so that we don't have to maintain their signatures.
7846 (yyFail): Check for buffer overflow, by using vsnprintf rather
7847 than vsprintf. Allocate a bigger buffer if possible.
7848 Report an error if buffer allocation fails.
7849 (yyStackOverflow): New function.
7850 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
7851 the initialization was successful. It might fail if storage was
7853 (yyexpandGLRStack): Add more checks for storage allocation failure.
7854 Use yyStackOverflow to report failures.
7855 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
7856 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
7857 Don't assume stack number fits in int.
7858 (yysplitStack): Check for storage allocation failure.
7859 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
7860 can print diagnostics on storage allocation failure. All callers
7862 (yyresolveValue): Use yybool for boolean.
7863 (yyreportSyntaxError): Check for size-calculation overflow.
7864 This code is taken from yacc.c.
7865 (yyparse): Check for storage allocation errors when allocating
7868 2005-07-05 Akim Demaille <akim@epita.fr>
7870 Extract calc++ from the documentation.
7871 * doc/bison.texinfo (Calc++): Add the extraction marks.
7872 * examples/extexi: New, from the aborted GNU Programming 2E.
7873 Separate the different paragraph of a file with empty lines.
7874 * examples/Makefile: Use it to extract the whole calc++ example.
7876 2005-06-24 Akim Demaille <akim@epita.fr>
7878 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
7881 2005-06-22 Akim Demaille <akim@epita.fr>
7883 * doc/bison.texinfo (C++ Language Interface): First stab.
7884 (C++ Parsers): Remove.
7886 2005-06-22 Akim Demaille <akim@epita.fr>
7888 * data/lalr1.cc (yylex_): Honor %lex-param.
7890 2005-06-22 Akim Demaille <akim@epita.fr>
7892 Start a set of simple examples.
7893 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
7894 * examples/calc++/calc++-driver.hh,
7895 * examples/calc++/calc++-parser.yy,
7896 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
7897 * examples/calc++/compile, examples/calc++/test: New.
7899 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
7901 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
7902 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
7903 which stems from the 2005-05-27 patch.
7905 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
7907 * data/glr.c: Modify treatment of unused parameters to permit use
7908 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
7910 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
7912 Fix infringement on user name space reported by Janos Zoltan Szabo.
7913 * data/yacc.c (yyparse): strlen -> yystrlen.
7915 2005-05-30 Akim Demaille <akim@epita.fr>
7917 * data/lalr1.cc (_): New.
7918 Translate the various messages.
7920 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
7922 Fix infringement on user name space reported by Bruno Haible.
7923 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
7924 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
7925 the user's name space.
7926 (alloca): Include <stdlib.h> to get it, if it's not built in.
7927 (YYMALLOC, YYFREE): Define only if needed.
7928 (malloc, free): Declare, but only if needed, as this infringes on
7929 the user name space.
7931 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7933 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
7934 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
7936 * lib/ebitset.c (min, max): Undef before defining.
7937 * lib/vbitset.c (min, max): Likewise.
7938 * lib/subpipe.c (create_subpipe): Save local variables in case
7939 vfork clobbers them.
7941 2005-05-24 Bruno Haible <bruno@clisp.org>
7943 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
7944 error message syntax used by gcc-4.0.
7946 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
7948 * README: Mention m4 1.4.3. Remove obsolete advice about
7949 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
7951 * bootstrap: Remove workaround for problem I encountered with
7952 gettext 0.14.1; it seems to be fixed now.
7954 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
7956 * NEWS: Version 2.0a.
7958 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
7959 the previous change.
7961 Various maintainer cleanups.
7962 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
7963 conftest*, for benefit of CVS commands run at the same time as
7964 "configure". Add build-aux, since "bootstrap" now creates it and
7966 * Makefile.cfg (move_if_change): Remove.
7967 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
7968 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

7973 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
7975 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
7976 this is now the recommended name.
7977 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
7978 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
7979 ylwrap. These files now go into build-aux.
7980 * config/move-if-change: Remove.
7981 * config/prev-version.txt: Bump from 1.75 to 2.0.
7983 * bootstrap: Add stdio-safer, unistd-safer modules.
7984 Remove m4/glibc2.m4 (introduced by latest gnulib, but
7986 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
7987 fopen-safer.c, stdio-safer.h, unistd-safer.h.
7988 * lib/subpipe.c: Include "unistd-safer.h".
7989 (create_subpipe): Make sure all the newly-created
7990 file descriptors are > 2, so that diagnostics don't
7991 get sent down them (which might cause Bison to hang, in theory).
7992 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
7993 * src/files.c (xfopen): Use fopen_safer, not fopen.
7995 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
7996 yesterday's yacc.c fix.
7998 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
8000 * data/glr.c, data/lalr1.cc: Update copyright date.
8002 Fix a destructor bug reported by Wolfgang Spraul in
8003 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
8004 * data/yacc.c (yyabortlab): Don't call destructor, and
8005 don't set yychar to EMPTY.
8006 (yyoverflowlab): Don't call destructor.
8007 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
8008 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
8009 since we no longer output the message "discarding lookahead token
8012 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8014 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
8015 fix a small glitch in debugging output.
8016 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
8017 after YY_SYMBOL_PRINT where needed.
8019 (struct yyGLRState): Add some comments.
8020 (struct yySemanticOption): Add some comments.
8021 (union yyGLRStackItem): Add comment.
8023 (yymergeOptionSets): Correct this to properly perform the union,
8024 avoiding infinite reported by Michael Rosien.

8068 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
8070 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
8071 Problem reported by Ralf Menzel.
8073 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8075 * tests/actions.at: Test that stack overflow invokes destructors.
8076 From Marcus Holland-Moritz.
8077 * data/yacc.c (yyerrlab): Move the code that destroys the stack
8079 (yyreturn): to here. That way, destructors are called properly
8080 even if the stack overflows, or the user calls YYACCEPT or
8081 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
8082 (yyoverflowlab): Destroy the lookahead.
8084 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
8086 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
8088 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
8090 * NEWS: Bison-generated C parsers no longer quote literal strings
8091 associated with tokens.
8092 * src/output.c (prepare_symbols): Don't escape strings,
8093 since users don't want to see C escapes.
8094 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
8096 * tests/input.at (Torturing the Scanner): Likewise.
8097 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
8099 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
8101 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
8102 the data size is known to be too small and we can't increase it.
8103 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
8105 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
8107 * src/parse-gram.y: Include quotearg.h.
8108 (string_as_id): Quote $1 before using it as a key, since the
8109 lexer no longer quotes it for us.
8110 (string_content): Don't strip quotes, since lexer no longer
8112 * src/scan-gram.l: Include quotearg.h.
8114 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
8115 a key, since the rest of the lexer doesn't quote it.
8116 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
8117 * tests/regression.at (Token definitions): Check for backslashes
8120 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
8121 (YYSIZE_T): Define to unsigned long int when using an older compiler.
8122 (yyparse): Revamp code to generate long syntax error message, to
8123 make it easier to translate, and to avoid problems with arithmetic
8124 overflow. Change "virtual memory" to "memory" in diagnostic, since
8125 we don't know whether the memory is virtual.
8127 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8129 * NEWS: Bison-generated C parsers now use the _ macro to
8131 * data/yacc.c (_) [!defined _]: New macro.
8132 All English strings wrapped inside this macro.
8133 * doc/bison.texinfo (Bison Parser): Document _.
8134 * po/POTFILES.in: Include src/parse-gram.c, since it now
8135 includes translateable strings that parse-gram.y doesn't.
8137 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
8139 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
8140 reverting the 2004-10-11 change to this function.
8141 (symbol_check_alias_consistency): Don't call symbol_type_set
8142 if the type name is already correct.
8143 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
8145 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
8147 * tests/regression.at (Token definitions): Don't use a token named
8148 c, as that generates a "#define c ..." that runs afoul of buggy
8149 stdlib.h that uses the identifier c as a member of struct
8150 drand48_data. Problem reported by Horst Wente.
8152 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
8154 * bootstrap: Change translation URL from
8155 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
8156 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
8157 redirection glitches. Problem reported by twlevo@xs4all.nl.
8159 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
8161 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
8162 after operands; POSIX says this isn't portable for the c99 command.
8164 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
8166 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
8167 immediately if a data overrun has occurred; this may help us track
8168 down what may be a spurious failure on MacOS.
8170 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
8172 Respond to problems reported by twlevo@xs4all.nl.
8174 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
8176 * src/vcg.h: Comment fix.
8177 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
8178 (G_CMAX): Change to -1 instead of INT_MAX.
8180 * data/yacc.c (yyparse): Omit spaces before #line.
8182 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
8184 * src/tables.c (state_number_to_vector_number): Put it inside an
8185 "#if 0", since it's not currently used. Problem reported by
8188 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
8190 * src/output.c (escaped_output): Renamed from
8191 escaped_file_name_output, since we now use it for symbol tags as
8192 well. All uses changed.
8193 (symbol_destructors_output, symbol_printers_output):
8194 Escape symbol tags too.
8195 Problem reported by Matyas Forstner in
8196 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
8198 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
8200 * src/output.c (user_actions_output, token_definitions_output,
8201 symbol_destructors_output, symbol_printers_output): Likewise.
8202 * src/reader.c (prologue_augment): Likewise.
8203 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
8205 * src/vcg.c (output_edge): Don't quote linestyle arg.
8206 Problem reported by twlevo@xs4all.nl.
8208 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
8210 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
8211 example, reported by Derek M Jones. Also, make the example even
8212 more outrageous, to better illustrate how bad the problem is.
8214 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
8216 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
8217 putsym. Typo reported by Sebastian Piping.
8219 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8221 * doc/bison.texinfo (Language and Grammar): some -> same
8222 (Epilogue): int he -> in the
8223 Typos reported by Sebastian Piping via Justin Pence.
8225 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8227 * tests/glr-regression.at (Improper handling of embedded actions
8228 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
8229 embedded actions and $-N in GLR parsers", work around an Autoconf bug
8230 with dollar signs in test names.
8231 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
8232 for a similar reason.
8234 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8236 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
8237 wants to redefine G_VIEW.
8239 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
8241 * src/vcg.c (get_view_str): Remove case for normal_view.
8242 Problem reported by twlevo@xs4all.nl.
8244 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
8246 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
8247 Problem reported by twlevo@xs4all.nl.
8249 * doc/bison.texinfo: Change @dircategory from "GNU programming
8250 tools" to "Software development". Requested by Richard Stallman
8253 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
8255 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
8256 Problem reported by twlevo@xs4all.nl.
8258 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8260 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
8261 keyword; it's not needed with modern compilers, and it doesn't
8262 affect correctness with older compilers. Suggested by
8265 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
8267 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
8268 gcc -Wswitch-default.
8269 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
8270 * data/yacc.c (yyparse): Likewise.
8272 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
8274 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
8275 already. Let config.h define any nonstandard values.
8277 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
8279 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
8280 for the benefit of slower hosts. Problem reported by
8283 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
8285 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
8286 being defined and not used.
8287 * data/lalr1.cc (yyparse): Likewise.
8288 Use "if (false)" rather than "if (0)".
8290 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
8292 * TODO: Mention that we should allow NUL bytes in tokens.
8294 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
8296 * src/scan-skel.l (<<EOF>>): Don't close standard output.
8297 Problem reported by Hans Aberg.
8299 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
8301 * src/getargs.c (version): Happy new year; update overall
8302 program copyright date from 2004 to 2005.
8304 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
8305 Problem reported by Hans Aberg.
8306 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
8307 (Output file names.): Add a test for the case when standard output
8310 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
8312 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
8313 to fix an oversight in the Bison 2.0 manual.
8315 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
8317 * NEWS: Version 2.0. Reformat the existing news items since
8318 1.875, so that related items are grouped together.
8319 * configure.ac (AC_INIT): Bump version to 2.0.
8320 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
8322 * tests/torture.at (Exploding the Stack Size with Alloca): Set
8323 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
8324 otherwise, we're not testing alloca. Unfortunately there's no
8325 simple way to consult HAVE_ALLOCA here.
8327 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
8330 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
8331 hand. This avoids a warning about comparing int to size_t when
8332 GCC warnings are enabled.
8334 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
8336 * NEWS: Bison-generated parsers no longer default to using the
8337 alloca function (when available) to extend the parser stack, due
8338 to widespread problems in unchecked stack-overflow detection.
8339 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
8340 responsibility to set it to a positive value. This lets the user
8341 specify a value that is not a preprocessor constant.
8342 * data/yacc.c (YYMAXDEPTH): Likewise.
8343 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
8344 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
8345 to be a compile-time constant. However, explain the constraints on it.
8346 Also, explain the constraints on YYINITDEPTH.
8347 (Table of Symbols): Explain that alloca is no longer the default.
8348 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
8351 * doc/bison.texinfo (Location Default Action): Mention that n must
8352 be zero when k is zero. Suggested by Frank Heckenbach.
8354 2004-12-22 Akim Demaille <akim@epita.fr>
8356 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
8357 (parser::state_type, parser::semantic_type, parser::location_type):
8358 Private, not public.
8359 (parser::parse): Return ints, not bool.
8360 Returning a bool introduces a problem: 0 corresponds to false, and
8361 it seems weird to return false on success. Returning true changes
8362 the conventions for yyparse.
8363 Alternatively we could return void and send an exception.
8364 There is no clear consensus (yet?).
8365 (state_stack, semantic_stack, location_stack): Rename as...
8366 (state_stack_type, semantic_stack_type, location_stack_type): these.
8367 Private, not public.
8368 * tests/c++.at: New.
8369 * tests/testsuite.at, tests/Makefile.am: Adjust.
8371 2004-12-21 Akim Demaille <akim@epita.fr>
8373 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
8375 2004-12-21 Akim Demaille <akim@epita.fr>
8377 Don't impose std::string for filenames.
8379 * data/lalr1.cc (b4_filename_type): New.
8380 (position::filename): Use it.
8381 (parser.hh): Move the inclusion of stack.hh and location.hh below
8382 the user code, so that needed headers for the filename type can be
8384 Forward declare them before the user code.
8385 * tests/Makefile.am (check-local, installcheck-local): Pass
8386 TESTSUITEFLAGS to the TESTSUITE.
8388 2004-12-20 Akim Demaille <akim@epita.fr>
8390 Use more STL like names: my_class instead of MyClass.
8392 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
8393 (SemanticStack, SemanticType, StateStack, StateType)
8394 (TokenNumberType, Stack, Slice, Traits, Parser::location)
8395 (Parser::value): Rename as...
8396 (location_stack, location_type, rhs_number_type, semantic_stack)
8397 (semantic_type, state_stack, state_type, token_number_type, stack)
8398 (slice, traits, parser::yylloc, parser::yylval): these.
8400 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
8402 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
8404 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
8405 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
8407 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
8409 Remove uses of 'short int' and 'unsigned short int'. This raises
8410 some arbitrary limits. It uses more memory but nowadays that's
8411 not much of an issue.
8413 This change does not affect the generated parsers; that's a different
8414 task, as some users will want to conserve memory there.
8416 Ideally we should use size_t to represent all object counts, and
8417 something like ptrdiff_t to represent signed differences of object
8418 counts; but that will require more code-cleanup than I have the
8419 time to do right now.
8421 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
8422 Use size_t, not int or short int, to count objects.
8423 * src/closure.c (nritemset, closure): Likewise.
8424 * src/closure.h (nritemset, closure): Likewise.
8425 * src/nullable.c (nullable_compute): Likewise.
8426 * src/print.c (print_core): Likewise.
8427 * src/print_graph.c (print_core): Likewise.
8428 * src/state.c (state_compare, state_hash): Likewise.
8429 * src/state.h (struct state): Likewise.
8430 * src/tables.c (default_goto, goto_actions): Likewise.
8432 * src/gram.h (rule_number, rule): Use int, not short int.
8433 * src/output.c (prepare_rules): Likewise.
8434 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
8435 errs, reductions): Likewise.
8436 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
8438 * src/tables.c (vector_number, tally, action_number,
8439 ACTION_NUMBER_MINIMUM): Likewise.
8440 * src/output.c (muscle_insert_short_int_table): Remove.
8442 2004-12-17 Akim Demaille <akim@epita.fr>
8444 * data/lalr1.cc: Extensive Doxygenation.
8445 (error_): Rename as...
8446 (error): this, since it is visible to the user.
8448 (Parser::message): Now an automatic variable from...
8449 (Parser::yyreport_syntax_error_): here.
8450 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
8452 * tests/input.at: Escape $.
8454 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
8456 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
8457 Parenthesize rhs to avoid obscure problems with mistakes like
8458 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
8459 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
8460 b4_rhs_location): Likewise.
8461 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
8462 b4_rhs_location): Likewise.
8464 2004-12-16 Akim Demaille <akim@epita.fr>
8466 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
8467 yacc.c: be sure to stay within yycheck_.
8468 * tests/actions.at: Re-enable C++ tests.
8470 2004-12-16 Akim Demaille <akim@epita.fr>
8472 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
8475 2004-12-16 Akim Demaille <akim@epita.fr>
8477 Use #define to handle the %name-prefix.
8479 * data/glr.c, data/yacc.c: Comment changes.
8480 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
8481 so that one can refer to yylex in the parser file, and have it
8482 renamed, as is the case with other skeletons.
8484 2004-12-16 Akim Demaille <akim@epita.fr>
8486 Move lalr1.cc internals into yy*.

8506 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
8508 Fix some problems reported by twlevo at xs4all.
8509 * src/symtab.c (symbol_new): Report an error if the input grammar
8510 contains too many symbols. This is better than calling abort() later.
8511 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
8512 (struct node, struct graph):
8513 Rename member expand to stretch. All uses changed.
8514 (struct graph): Remove member layoutalgorithm. All uses removed.
8515 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
8516 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
8518 (N_STRETCH): Rename from N_EXPAND. All uses changed.
8520 2004-12-15 Akim Demaille <akim@epita.fr>
8522 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
8523 Add more Doxygen comments.
8524 (symprint_, stack_print_, reduce_print_, destruct_, pop)
8525 (report_syntax_error_, translate_): Rename as...
8526 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
8527 (yypop_, yyreport_syntax_error_, yytranslate_): this.
8529 2004-12-15 Akim Demaille <akim@epita.fr>
8531 * data/lalr1.cc (lex_): Rename as...
8533 Move the trace here.
8534 Take the %name-prefix into account.
8535 Reported by Alexandre Duret-Lutz.
8537 2004-12-15 Akim Demaille <akim@epita.fr>
8539 Simplify the C++ parser constructor.
8541 * data/lalr1.cc (debug_): Rename as...
8542 (yydebug_): so that the parser's internals are always in the yy*
8545 (b4_parse_param_decl): Remove the leading comma as it is now only
8546 called as unique argument list.
8547 (Parser::Parser): Remove the constructor accepting a location and
8548 an initial debugging level.
8549 Remove from the other ctor the argument for the debugging level.
8550 (debug_level_type, debug_level, set_debug_level): New.
8552 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
8555 2004-12-15 Akim Demaille <akim@epita.fr>
8557 Remove b4_root related material: failure experiment
8558 (which goal was to allow to derive from a class).
8560 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
8561 definitions and uses.
8563 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
8565 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
8566 not 2, since it's not portable to subtract 1 from the start of an
8567 array. The new item 0 is never set or used. All uses changed.
8569 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
8570 the default definition of YYLLOC_DEFAULT. Problem reported
8571 by Frank Heckenbach.
8573 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
8575 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
8576 the normal case and one for the error case. Just use the
8577 first one uniformly. Problem reported by Frank Heckenbach.
8578 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
8579 use exactly the same macro in both places.
8580 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
8581 so that the normal-case YYRHSLOC works for the error case too.
8583 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
8584 (YYLLOC_DEFAULT): Use the same macro as glr.c.
8585 * doc/bison.texinfo (Location Default Action): Don't claim that
8586 we have an array of locations. Use the same macro for both glr
8587 and lalr parsers. Mention YYRHSLOC. Mention what happens when
8590 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
8592 * HACKING: Update email addresses to send announcements to.
8594 * configure.ac (AC_INIT): Bump version to 1.875f.
8596 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
8598 * NEWS: Version 1.875e.
8599 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
8601 * src/scan-skel.l: Include "complain.h", for "fatal".
8603 * src/relation.h (relation_print, relation_digraph):
8604 Relation sizes are of type relation_node, not size_t (this is
8605 merely a doc fix, since the two types are equivalent).
8606 (relation_transpose): Relation sizes are of type relation_node,
8608 * src/relation.c: Likewise.
8609 (top, infinity): Now of type relation_node, not int.
8610 (traverse, relation_transpose): Use relation_node, not int.
8612 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
8613 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
8614 (yyparse): Remove unused local introduced in 2004-10-25 patch.
8616 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
8617 specifying whether the test should be skipped. Use it tp
8618 specify that the [%defines %skeleton "lalr1.cc"] tests currently
8619 fail on some hosts, and should be skipped.
8621 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
8623 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
8624 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
8625 unless otherwise specified below.
8627 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
8628 to allocate kernel_base, kernel_items, kernel_size, since
8629 they needn't be initialized to 0.
8630 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
8631 * src/closure.c (new_closure): Likewise, for itemset.
8632 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
8633 * src/lalr.c (set_goto_map): Likewise, for temp_map.
8634 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
8635 (build_relations): Likewise for edge, states1, includes.
8636 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
8637 * src/reader.c (packgram): Likewise, for ritem, rules.
8638 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
8639 * src/relation.c (relation_digraph): Likewise for VERTICES.
8640 (relation_transpose): Likewise for new_R, end_R.

8644 (token_actions): Likewise for yydefact, actrow, conflrow,
8646 (save_column): Likewise for froms[symno], tos[symno].
8647 (goto_actions): Likewise for state_count.
8648 (pack_table): Likewise for base, pos, check.
8649 (tables_generate): Likewise for width.
8651 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
8652 for initial core. Just have a separate core, so we needn't worry
8653 about whether kernel_size and kernel_base are initialized.
8655 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
8656 kernel_size, kernel_items): Remove unnecessary initialization.
8657 * src/conflicts.c (conflicts): Likewise.
8658 * src/derives.c (derives): Likewise.

8661 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
8662 conflrow, conflict_table, conflict_list, table, check):
8665 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
8666 This is because all callers pass unsigned int.
8667 * src/closure.h (new_closure): Likewise.
8669 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
8670 (build_relations): Initialize includes[i] in all cases.
8671 * src/reader.c (packgram): Always initialize rules[ruleno].prec
8672 and rules[ruleno].precsym. Initialize members in order.
8673 * src/relation.c (relation_transpose): Always initialize new_R[i]
8675 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
8677 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
8678 conflict_list[0] was always 0, but now it isn't initialized.
8680 * src/table.c (table_grow): When conflict_table grew, the grown
8681 area wasn't cleared. Fix this.
8683 * lib/.cvsignore: Add strdup.c, strdup.h.
8684 * m4/.cvsignore: Add strdup.m4.
8686 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
8688 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
8689 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
8690 GOTO_NUMBER_MAXIMUM, since we occasionally compute
8691 ngotos + 1 without checking for overflow.
8692 (build_relations): Use END_NODE, not -1, to denote end of edges.
8693 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
8694 build_relations): Use goto_number, not int, for goto numbers.
8695 * src/tables.c (save_column, default_goto): Likewise.
8697 2004-11-23 Akim Demaille <akim@epita.fr>
8699 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
8700 of #defining from yystype.
8701 Don't typedef yystype, C++ does not need it.
8702 This lets it possible to forward declare it as union.
8704 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
8706 * bootstrap (gnulib_modules): Add extensions.
8707 Problem reported by Jim Meyering.
8709 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
8711 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
8712 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
8713 src/system.h, src/tables.c: XFREE -> free, to accommodate
8714 recent change to gnulib xalloc.h.
8715 Problem reported by Jim Meyering.
8717 2004-11-17 Akim Demaille <akim@epita.fr>
8719 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
8721 2004-11-17 Akim Demaille <akim@epita.fr>,
8722 Alexandre Duret-Lutz <adl@gnu.org>
8724 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
8727 Use it instead of cdebug_.
8728 (Parser::debug_stream, Parser::set_debug_stream): New.
8729 (Parser::symprint_): Define cdebug_ for temporary backward
8731 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
8734 2004-11-17 Akim Demaille <akim@epita.fr>
8736 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
8737 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
8738 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
8739 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
8741 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
8743 * data/glr.c (yyloc_default): Remove; not used.
8744 Problem reported by Frank Heckenbach.
8746 2004-10-25 Akim Demaille <akim@epita.fr>
8748 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
8749 Introduce another definition to address simple location arrays.
8750 (yyGLRStack): New member: yyerror_range.
8751 (yyrecoverSyntaxError, yyparse): Update it.
8752 (yyrecoverSyntaxError): Use it when shifting the error token to
8753 have an accurate range, equivalent to the one computed by both
8754 yacc.c and lalr1.cc.
8755 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
8756 that column numbers start at column 0, as per GNU Coding
8757 Standards, the others tests, and the doc.
8758 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
8759 Adjust to the above change (first column is 0).
8760 And adjust the location of the "<error>", now covering the whole
8763 2004-10-22 Akim Demaille <akim@epita.fr>
8764 and Paul Eggert <eggert@cs.ucla.edu>
8766 Remove some arbitrary limits on goto numbers and relations.
8767 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
8768 initial values, since they're never used.
8769 (set_goto_map): ngotos is now unsigned, so test for overflow
8770 by seeing whether it wraps around to zero.
8771 * src/lalr.h (goto_number): Now size_t, not short int.
8772 (GOTO_NUMBER_MAXIMUM): Remove.
8773 * src/relation.c (relation_print, traverse, relation_transpose):
8774 Check for END_NODE rather than looking at sign.
8775 * src/relation.h (END_NODE): New macro.
8776 (relation_node): Now size_t, not short int.
8778 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
8780 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
8781 keyword, not an identifier. Problem reported by Baron Schwartz in
8782 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
8784 2004-10-11 Akim Demaille <akim@epita.fr>
8786 * src/symtab.c (symbol_check_alias_consistency): Also check
8787 type names, destructors, and printers.
8788 Reported by Alexandre Duret-Lutz.
8789 Recode the handling of associativity and precedence in terms
8790 of symbol_precedence_set.
8791 Accept no redeclaration at all, not even equal to the previous
8793 (redeclaration): New.
8794 Use it to factor redeclaration complaints.
8795 (symbol_make_alias): Don't set the type of the alias, let
8796 symbol_check_alias_consistency do it as for other features.
8797 * src/symtab.h (symbol): Add new member prec_location, and
8799 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
8800 * tests/input.at (Incompatible Aliases): New.
8802 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
8804 .cvsignore fixes to accommodate gnulib changes,
8805 and the practice of naming build directories "_build".
8806 * .cvsignore: Add "_*". Sort.
8807 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
8808 * m4/.cvsignore: Add "*_gl.m4".
8810 2004-10-06 Akim Demaille <akim@epita.fr>
8812 * src/parse-gram.y (add_param): Fix the truncation of trailing
8815 2004-10-05 Akim Demaille <akim@epita.fr>
8817 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
8818 whether the reducion was empty or not. This leaves room to
8819 improve the use of YYLLOC_DEFAULT in such a case.
8820 lalr1.cc is still experimental, so changing this is acceptable.
8821 And finally, there are probably not many users who changed the
8822 handling of locations in GLR, so changing is admissible too.
8824 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
8825 empty reduction, set @$ to an empty location ending the previously
8827 Adjust uses to make sure the code is triggered on empty
8829 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
8830 expected output: empty reductions have empty locations.
8832 2004-09-29 Akim Demaille <akim@epita.fr>
8834 * data/lalr1.cc: Move towards a more standard C++ coding style
8835 for templates: Class < T > -> Class<T>.
8837 2004-09-29 Akim Demaille <akim@epita.fr>
8839 * data/lalr1.cc: Reinstall the former ctor, for sake of
8840 compatibility, but warn it will be removed.
8841 Move towards a more standard C++ coding style (i.e., type *var ->
8844 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
8846 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
8847 since it's less likely to work if NULs are involved in the future.
8849 2004-09-27 Akim Demaille <akim@epita.fr>
8851 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
8853 2004-09-27 Akim Demaille <akim@epita.fr>
8855 * data/lalr1.cc (b4_parse_param_decl_1): New.
8856 (b4_parse_param_decl): Use it to have different names between attribute
8858 (b4_cc_constructor_call): Likewise.
8860 2004-09-24 Akim Demaille <akim@epita.fr>
8862 * src/parse-gram.y (add_param): Strip the leading and trailing
8863 blanks from a formal argument declaration.
8864 (YY_LOCATION_PRINT): New.
8866 2004-09-24 Akim Demaille <akim@epita.fr>
8868 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
8871 2004-09-24 Akim Demaille <akim@epita.fr>
8873 * doc/bison.texinfo (Table of Symbols): Sort.
8875 2004-09-21 Akim Demaille <akim@epita.fr>
8877 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
8878 the useless parentheses.
8879 Suggested by Paul Eggert.
8881 2004-09-20 Akim Demaille <akim@epita.fr>
8883 Let the initial-action act on the look-ahead, and use it for the
8884 "initial push" (corresponding to an hypothetical beginning-of-file).
8885 And let lalr1.cc honor %initial-action.
8887 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
8889 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
8890 (Parser::Parser): Remove the ctor that used to initialize it.
8891 (Parser::parse): Like in the other skeletons, issue the "starting
8892 parse" message before any action.
8893 Honor %initial-action.
8894 Initialize the stacks with the lookahead.
8895 * data/yacc.c: Let $$ and @$ in %initial-action designate the
8897 Push them in the stacks.
8898 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
8900 2004-09-20 Akim Demaille <akim@epita.fr>
8902 * doc/bison.texinfo (Initial Action Decl): New.
8904 2004-09-20 Akim Demaille <akim@epita.fr>
8906 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
8907 clearer criterion to define it.
8908 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
8909 When reducing on an empty RHS, use the latest stacked location as
8911 yylloc is not always available.
8912 * data/glr.c: Likewise.
8913 Also, honor initial-actions.
8915 2004-09-20 Akim Demaille <akim@epita.fr>
8917 * data/yacc.c (YY_LOCATION_PRINT): New.
8918 Define when we know YYLTYPE's structure, i.e., when the default
8919 YYLLOC_DEFAULT is used.
8920 * data/c.m4 (b4_yysymprint_generate): Use it.
8921 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
8922 value of the result.
8923 (error_start_): Replace with...
8924 (error_range_): this location array.
8925 This allows to replace code relying on the implementation of
8926 locations by portable code.
8927 * data/yacc.c (yylerrsp): Replace with...
8928 (yyerror_range): this.
8929 Every time a token is popped, update yyerror_range[0], to have an
8930 accurate location for the error token.
8931 * data/glr.c (YY_LOCATION_PRINT): New.
8932 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
8933 deference a pointer.
8934 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
8935 report the location in %printers.
8937 * src/scan-skel.l: Instead of abort, report error messages to ease
8938 understanding skeleton scanning failures.
8940 2004-09-16 Akim Demaille <akim@epita.fr>
8942 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
8943 (iterator, const_iterator): these, to be more in the C++ spirit.
8944 Also, return reverse iterators so that when displaying the stack
8945 we display its bottom first.
8946 (Parser::stack_print_, Parser::reduce_print_): Match the messages
8948 We should probably use vector here though.
8950 2004-09-16 Akim Demaille <akim@epita.fr>
8952 Have more complete shift traces.
8954 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
8955 to report Shifts instead of ad hoc YYDPRINTF invocations,
8956 including for the error token.
8957 * data/lalr1.cc (symprint_): Output the location.
8958 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
8959 output the location within the %printer.
8960 Activate GLR tests, at least to make sure they compile properly.
8961 They still don't pass though.
8962 * tests/calc.at: Adjust expect verbose output, since now "Entering
8963 state..." is on a different line than the "Shifting" message.
8965 2004-09-08 Akim Demaille <akim@epita.fr>
8967 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
8968 Bison directive from the Bison file to the invocation of this
8969 macro, so that these directives are passed to
8970 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
8971 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
8972 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
8973 the extra Bison directives instead of the whole series.
8974 Change the grammar so that there are recoverable errors, and
8975 unrecoverable errors. Now we can have the parser give up before
8976 consuming the whole input. As a result we now can observe that
8977 the lookahead is freed when needed.
8978 Change the parser source to parse argv[1] instead of a hard coded
8980 Simplify yylex, and give a value and location to EOF.
8981 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
8982 passed directives already coded in the file.
8983 Add some tests to check the location of "error".
8984 For some tests, the C++ parser is correct, and not yacc.c.
8985 For other tests, they provide different, but unsatisfying, values,
8986 so keep the C++ value so that at least one parser is "correct"
8987 according to the test suite.
8988 (Actions after errors): Remove, this is subsumed by the
8989 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
8991 2004-09-06 Akim Demaille <akim@epita.fr>
8993 * data/lalr1.cc: Adjust the indentation of the labels.
8997 2004-09-06 Akim Demaille <akim@epita.fr>
8999 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
9000 argument, an informative message.
9001 Call YY_SYMBOL_PRINT.
9002 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
9003 * data/lalr1.cc (destruct_): Likewise.
9004 In addition, no longer depend on b4_yysymprint_generate and
9005 b4_yydestruct_generate to generate these functions, do it "by
9008 2004-09-03 Akim Demaille <akim@epita.fr>
9010 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
9011 invoked, yydestruct the lookahead.
9012 * tests/calc.at (Calculator $1): Update the expected lengths of
9013 traces: there is an added line for the discarded lookahead.
9014 * doc/bison.texinfo (Destructor Decl): Some rewording.
9015 Define "discarded" symbols.
9017 2004-09-02 Akim Demaille <akim@epita.fr>
9019 * data/lalr1.cc (translate_, destruct_): No reason to be static.
9021 2004-09-02 Akim Demaille <akim@epita.fr>
9023 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
9024 (YYDSYMPRINTF): Rename as...
9025 (YY_SYMBOL_PRINT): this.
9026 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
9028 Use it instead of direct symprint_ calls.
9029 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
9032 2004-09-02 Akim Demaille <akim@epita.fr>
9034 * data/lalr1.cc (b4_yysymprint_generate): New.
9035 (symprint_): New member function, defined when YYDEBUG.
9036 Use it consistently instead of token/nterm debugging output by
9038 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
9039 %printer calls to use cdebug_ when using lalr1.cc.
9041 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
9043 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
9044 with #ifdef YYDEBUG.
9046 2004-08-26 Akim Demaille <akim@epita.fr>
9048 * doc/bison.texinfo (Implementing Loops): Rename as...
9049 (Implementing Gotos/Loops): this.
9051 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
9053 Adjust to latest gnulib.
9054 * bootstrap (gnulib_modules): Add xalloc-die.
9055 Set LC_ALL=C so that file names sort consistently.
9056 Prefer the gnulib copies of gettext.m4, glibc21.m4,
9057 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
9058 uintmax_t.m4, ulonglong.m4.
9059 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
9060 po.m4 since we are now using _gl.m4 instead.
9062 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
9064 * src/scan-action.l: Remove. Scanning of semantic actions is
9065 handled in scan-gram.l.
9067 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
9069 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
9071 * src/location.h (struct): The file member is a uniqstr.
9072 (equal_boundaries): Use UNIQSTR_EQ for comparison.
9074 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
9076 Fix bug with non-%union parsers that have printers or destructors,
9077 which led to a Bison core dump. Reported by Peter Fales in
9078 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
9080 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
9081 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
9082 not to our own type.
9083 * src/output.c (symbol_destructors_output, symbol_printers_output):
9084 Don't assume %union.
9085 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
9086 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
9087 UNION-FLAG. All callers changed.
9088 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
9089 Use type char, not unsigned int, when declaring an array of char;
9090 this lets us remove a cast.
9091 (Printers and Destructors): Add non-%union test cases.
9093 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9095 * doc/bison.texinfo: Minor editorial changes, mostly to the new
9096 GLR writeups. E.g., avoid frenchspacing and the future tense,
9097 change "lookahead" to "look-ahead", and change "wrt" to "with
9100 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9102 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
9103 New sections, split off from the GLR Parsers section. Put the new
9104 Simple GLR Parser near the start of the GLR section, for clarity.
9105 Rewrite connective text.
9107 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
9109 * doc/bison.texinfo (Simple GLR Parsers): New section.
9111 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9113 * NEWS, TODO, doc/bison.texinfo:
9114 Use "look-ahead" instead of "lookahead", to be consistent.
9115 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
9116 while we're fixing "look-ahead".
9117 * src/conflicts.c (shift_set): Renamed from shiftset.
9118 (look_ahead_set): Renamed from lookaheadset.
9119 * src/print.c: Likewise.

9133 * tests/torture.at (AT_DATA_LOOK_AHEAD_TOKENS_GRAMMAR): Renamed from
9134 AT_DATA_LOOKAHEADS_GRAMMAR.
9136 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
9138 * README: Update location of patched M4 distribution.
9140 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
9142 Don't assume the C++ compiler takes the same arguments as the C compiler
9144 * configure.ac (O0CXXFLAGS): New var.
9145 * tests/atlocal.in (CXXFLAGS): Use it.
9147 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
9149 Fix some "make check" problems with C++ reported by
9150 Albert Chin-A-Young for Tru64 C++ in this thread:
9151 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
9153 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
9154 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9155 Output to a .cc file for C++, not to a .c file.

9157 * tests/regression.at (AT_CHECK_DANCER): Likewise.
9158 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
9160 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
9162 * tests/calc.at, tests/actions.at: Workaround for SGI
9163 C++ compiler. (trivial change)
9165 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
9167 Spent a few hours checking out which prerequisite versions the
9168 current sources actually require. I went all the way back to
9169 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
9170 a seemingly endless set of combinations of versions more recent
9171 than that. The bottom line is that the current sources require
9172 fairly recent versions of the build tools, and it'll be some work
9174 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
9175 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
9176 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
9177 Add comments explaining why those particular versions are
9180 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
9181 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
9182 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
9184 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
9185 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
9187 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9189 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
9190 0.11.5. Suggested by Bruno Haible.
9191 * bootstrap: Remove gettext version checking.
9193 * doc/bison.texinfo (Decl Summary): Also mention that %union
9194 can depend on prerequisite types. Problem reported by Tim
9197 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9199 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
9200 * README-alpha: Don't tell people not to package this.
9202 * bootstrap: Don't assume $(...) works; use `...` instead.
9203 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
9206 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
9207 put into the -d output file, and mention what to do if YYSTYPE is
9210 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9212 Undo change made earlier today: it caused autopoint to not bring
9213 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
9216 * bootstrap: Check that gettext version matches what's in
9217 configure.ac. Warn users to ignore robots.txt ERROR 404.
9218 * bootstrap: Undo today's earlier change (logged below).
9219 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
9221 The gettext version checking is causing more trouble than it's
9222 curing; remove it. Problem reported by Paul Hilfinger.
9224 * bootstrap: Issue a warning that one can expect a message
9225 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
9226 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
9228 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
9230 Ensure that the C++ compiler used for testing actually works on a
9231 simple test program; if not, skip the C++-related tests. Problem
9232 reported by Vin Shelton in:
9233 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
9235 * m4/cxx.m4: New file.

9242 * data/glr.c (yylloc): Output this macro even if locations are not
9243 being generated, as the GLR parser needs it even in that case.
9244 Problem reported by Troy A. Johnson
9245 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
9247 * configure.ac (AC_INIT): Update to 1.875e.

9255 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
9256 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
9257 lalr1.cc runs afoul of the first, and the last two are no longer
9258 supported by GCC 3.4.0.
9259 * README: Mention GNU m4 1.4 or later; mention m4 patches.
9260 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
9262 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
9264 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not

9275 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
9276 character and string literals.
9277 (unexpected_end): New function.
9278 (unexpected_eof): Use it.
9279 (unexpected_newline): New function.

9297 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
9298 * src/.cvsignore: Add *.output.
9300 * src/parse-gram.y: Put copyright notice inside %{ %} so it
9301 gets copied to the output file.
9303 2004-04-28 Paul Eggert <eggert@twinsun.com>
9305 Get files from the gnulib and po repositories, instead of relying
9306 on them being in our CVS. Upgrade to latest versions of gnulib
9309 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
9310 * bootstrap: Bootstrap from gnulib and po repositories.
9311 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
9312 * README-cvs: Document these changes. Remove version numbers from
9313 mentions of build tools, since they change so often. Mention Flex.

9317 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
9318 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
9320 (AC_ISC_POSIX): Remove; we no longer support this
9321 ancient OS, as it gets in the way of latest Autoconf & gnulib.
9322 (AC_HEADER_STDC): Remove: we now assume C89 or better.
9323 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
9324 Do not check for C89 headers, except for locale.h which is used
9325 by the Yacc library and must port to K&R hosts.
9326 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
9327 Do not check for C89 functions, except for setlocale which is
9328 used by the Yacc library.

9334 AM_GNU_GETTEXT): Remove; now done by:
9335 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
9336 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
9339 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
9340 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
9341 Define to empty, as gnulib.mk will do the rest for us.

9344 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
9345 (lib_SOURCES): New symbol, containing only the non-gnulib libs.

9350 (REALLOC): Use xnrealloc, for likewise.
9351 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
9352 (strnlen, memrchr): Remove decls; functions no longer used.

9375 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
9376 Remove, as these files are now generated automatically
9377 by bootstrap or automake.

9407 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
9408 case, as stos_ is now used by destructors due to the 2004-02-09
9411 Remove more K&R C support.

9433 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
9435 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
9436 so that this include file can stand alone.
9437 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
9438 does this now. Include subpipe.h first after config.h, to
9439 test whether it can stand alone.
9441 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
9442 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
9445 * tests/synclines.at (%union synch line): Put a dummy member in
9446 the union, because empty unions aren't allowed in C. Caught
9449 2004-04-13 Jim Meyering <jim@meyering.net>
9451 * src/conflicts.c (conflicts_print): Correct format string typo:

9517 2004-03-08 Paul Eggert <eggert@gnu.org>
9519 Add support for hex token numbers. Suggested by Odd Arild Olsen in
9520 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
9522 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
9524 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
9525 * src/scan-gram.l (scan_integer): New function.
9527 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
9528 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
9529 handle_action_dollar, handle_action_at, convert_ucn_to_byte):

9549 token which are discarded.
9550 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
9551 error_start_ when erroneous token are discarded.
9552 (Parser::parse) <yyerrlab1>: Compute the location of the error
9553 token so that it covers all the discarded tokens.
9554 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
9555 it can be called with `%skeleton "lalr1.cc"', and do that.
9557 2004-02-02 Paul Eggert <eggert@twinsun.com>
9559 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
9560 $(top_srcdir)/lib and ../lib. This fixes a bug reported
9561 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
9562 There's no need to mention top_builddir since Automake does that
9564 (INCLUDES): Remove, as Automake says it's obsolescent.
9565 Contents migrated into AM_CPPFLAGS as described above.

9577 resulting parsers are compilable with C++.
9579 2003-12-23 Paul Eggert <eggert@twinsun.com>
9581 * config/depcomp, config/install-sh: Sync with Automake 1.8.
9582 * src/output.c (output_skeleton): Rename local var.
9583 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
9584 Bison tokens, as this runs afoul of the 2003-10-07 change that
9585 disallowed NUL bytes in character constants or string literals.
9587 * tests/local.at: Require Autoconf 2.59's Autotest.
9588 * tests/testsuite.at: Don't include local.at, since we now assume
9589 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
9591 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
9592 multiple inclusion warnings.
9594 2003-12-02 Akim Demaille <akim@epita.fr>

9607 if testsuite doesn't exist.
9609 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
9610 literals, unfortunately.
9611 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):

9616 * NEWS: Don't document %no-default-prec, as it's still
9618 * doc/bison.texinfo: Document %no-default-prec only if

9621 2003-10-04 Paul Eggert <eggert@twinsun.com>
9623 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
9624 non-modifiable lvalue, instead of a modifiable one.
9625 * doc/bison.texinfo (Actions): Document that $$ can
9626 be assigned to. Do not claim that $$ and $N are

9689 When reducing initial empty rules, Bison parser read an initial
9690 location that is not defined. This results in garbage, and that
9691 affects Bison's own parser. Therefore we need (i) to extend Bison
9692 to support a means to initialize this location, and (ii) to use
9693 this CVS Bison to fix CVS Bison's parser.
9695 * src/reader.h, reader.c (epilogue_augment): Remove, replace

9731 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
9732 error recovery loops. This patch is based on
9733 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
9734 Also, augment the similarity between lalr1.cc and yacc.c.
9735 Note: the locations of error recovery rules are not correct yet.
9737 * data/lalr1.cc: Comment changes to augment the similarity between
9738 lalr1.cc and yacc.c.
9739 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
9740 (yyerrlab1): Remove, but where it used to be (now the bottom part of
9741 yyerrlab), when hitting EOF, pop the whole stack here instead of
9742 merely falling thru the default error handling mechanism.
9743 (yyerrorlab): New label, with the old contents of YYERROR,
9744 plus the following change: pop the stack of rhs corresponding
9745 to the production that invoked YYERROR. That is how Yacc
9746 behaves (required by POSIX).
9747 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
9750 2003-08-25 Akim Demaille <akim@epita.fr>
9752 Tune local.at so that people can "autom4te -l autotest calc.at -o
9753 calc" for instance, to extract a sub test suite.
9755 * tests/testsuite.at: Move the initialization, Autotest version
9756 requirement, and AT_TESTED invocation into...
9757 * tests/local.at: here.
9758 * tests/testsuite.at: Include it for compatibility with Autoconf
9760 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
9763 2003-08-04 Paul Eggert <eggert@twinsun.com>
9765 Rework code slightly to avoid gcc -Wtraditional warnings.
9766 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
9767 The returned value is now stored in *YY0. All callers changed.
9768 * src/output.c (merge_output): Adjust to the above change.
9770 2003-07-26 Paul Eggert <eggert@twinsun.com>
9772 * data/glr.c (YYASSERT): New macro.
9773 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
9774 yyresolveStates, yyprocessOneStack):
9775 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
9776 Derived from a suggestion by Frank Heckenbach.
9778 2003-07-25 Paul Eggert <eggert@twinsun.com>
9780 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
9781 for portability to K&R C (after ansi2knr, presumably). See
9782 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
9783 by Frank Heckenbach, though I have omitted the structure-initialization
9784 part of his glr-knr.diff patch since I recall that the Portable
9785 C Compiler didn't require that change.
9787 Let the user specify how to allocate and free memory.

9790 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
9791 All uses of free, malloc, realloc changed to use these macros,
9792 and unnecessary casts removed.

9795 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
9797 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):

9820 when printing sizes. Print sizes using an unsigned format.
9821 Problem reported by Frank Heckenbach in

9826 declare a single dummy member, as empty structs do not conform
9828 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
9829 the Forte Developer 7 C compiler complains that end-of-loop

9875 `How Can I Reset @code{yyparse}', since texinfo does not allow
9876 arbitrary @ in node names.
9878 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
9879 shouldn't be needed according to the gettext 0.12.1 documentation
9880 but which seem to be needed anyway: codeset.m4 glibc21.m4
9881 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4

9903 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
9904 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
9905 the tests right now.
9906 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
9907 yyerror are declared before use; C99 requires this.
9909 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
9911 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
9913 (yyrecoverSyntaxError): Correct the logic for setting and testing
9915 Correct comment on handling EOF.
9916 Allow states with only a default reduction, rather than failing
9917 (I can't quite reconstruct why these were not allowed before).
9919 Fixes to avoid problem that $-N rules in GLR parsers can cause
9920 buffer overruns, corrupting state.
9922 * src/output.c (prepare_rules): Output max_left_semantic_context
9924 * src/reader.h (max_left_semantic_context): New variable declaration.

9939 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
9941 * tests/cxx-type.at: Exercise location information; update tests
9942 to differentiate output with and without locations.
9943 Remove forward declarations of yylex and yyerror---caused errors
9944 because default YYLTYPE not yet defined.
9945 Change semantic actions to compute strings, rather than printing
9946 them directly (to test proper passing of semantics values). Change
9947 output to prefix notation and update test data and expected results.
9948 (yylex): Track locations.
9949 (stmtMerge): Return value rather than printing, and include arguments

9962 Rename local vars to avoid warnings.
9963 * tests/glr-regression.at (Improper handling of embedded actions
9964 and $-N in GLR parsers): Remove unused local variable from yylex.
9965 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
9966 (void) as arg when not pure, since we now assume C89 when building
9967 Bison. Pacify GCC by using parameter.
9969 2003-06-02 Paul Eggert <eggert@twinsun.com>
9971 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
9972 yy::Location::lines, yy::Location::columns): Rename arguments
9973 to avoid shadowing; this removes a warning generated by GCC 3.3.
9975 2003-06-01 Paul Eggert <eggert@twinsun.com>
9977 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
9978 to g++, as GCC 3.3 complains if you do it.
9979 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
9980 everything that WARNING_CFLAGS has, except omit warnings
9981 not suitable for C++.
9982 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
9983 * tests/atlocal.in (CXXFLAGS): New var.
9984 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
9986 Fix a GLR parser bug I reported in February; see
9987 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
9988 The problem was that GLR parsers did not conform to the C standard,
9989 because actions like { $1 = $2 + $3; } expanded to expressions
9990 that invoked YYFILL in separate subexpressions, and YYFILL assigned
9991 to a local variable. The C standard says that expressions
9992 like (var = f ()) + (var = f ()) have undefined behavior.
9993 Another problem was that GCC sometimes issues warnings that
9994 yyfill and its parameters are unused.
9996 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
9998 (yyfill): New function.
10000 (yyuserAction): Change type of yynormal to bool, so that it matches
10001 the new yyfill signature. Mark it as possibly unused.
10004 Follow up on a bug I reported in February, where a Bison-generated
10005 parser can loop. Provide a test case and a fix for yacc.c. I
10006 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10007 The original bug report is in:
10008 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
10010 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10011 macro's size was becoming unwieldy.
10012 (yyerrlab): Do not discard an empty lookahead symbol, as this
10013 might destroy garbage.
10014 (yyerrorlab): New label, with the old contents of YYERROR,
10015 plus the following change: pop the stack of rhs corresponding
10016 to the production that invoked YYERROR. That is how Yacc
10017 behaves, and POSIX requires this behavior.
10018 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10019 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10020 Define 'alarm' to do nothing if unistd.h is not available.
10021 Add a new rule "exp: '-' error;" to test the above change to
10022 data/yacc.c. Use 'alarm' to abort any test taking longer than
10023 10 seconds, as it's probably looping.
10024 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10025 Also, the new yacc.c generates two fewer diagnostics for an
10028 2003-05-24 Paul Eggert <eggert@twinsun.com>
10030 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
10031 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
10032 This fixes a problem reported by John Bowman when the Compaq/HP
10033 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
10034 -ansi -Wall -gall).
10035 * data/yacc.c (union yyalloc): Likewise.
10036 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
10038 Switch from 'int' to 'bool' where that makes sense.
10040 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
10041 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
10042 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
10043 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
10044 Return or accept bool, not int. All callers changed.
10045 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
10046 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.

10048 bitset_copy_, bitset_op4_cmp, bitset_and_or_cmp_, bitset_andn_or_cmp_,

10051 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,
10052 bitset_stats_test, bitset_stats_empty_p, bitset_stats_disjoint_p,

10055 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
10056 bitset_stats_or_and_cmp): Likewise.
10057 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,

10060 ebitset_xor_cmp): Likewise.
10061 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
10062 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
10063 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
10064 lbitset_xor_cmp): Likewise.
10065 * lib/bbitset.h: Include <stdbool.h>.
10066 (struct bitset_vtable): The following members now return bool, not
10067 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
10068 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
10070 * src/conflicts.c (count_rr_conflicts): Likewise.
10071 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
10073 * lib/ebitset.c (ebitset_obstack_init): Likewise.
10074 * lib/lbitset.c (lbitset_obstack_init): Likewise.
10075 * src/getargs.c (debug_flag, defines_flag, locations_flag,
10076 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
10077 graph_flag): Likewise.
10078 * src/getargs.h (debug_flag, defines_flag, locations_flag,
10079 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
10080 graph_flag): Likewise.
10081 * src/output.c (error_verbose): Likewise.
10082 * src/output.h (error_verbose): Likewise.
10083 * src/reader.c (start_flag, typed): Likewise.
10084 * src/reader.h (typed): Likewise.
10085 * src/getargs.c (LOCATIONS_OPTION): New constant.
10086 (long_options, getargs): Use it.
10087 * src/lalr.c (build_relations): Use bool, not int.
10088 * src/nullable.c (nullable_compute): Likewise.
10089 * src/print.c (print_reductions): Likewise.
10090 * src/tables.c (action_row, pack_vector): Likewise.
10091 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
10092 * src/output.c (prepare): Use it.
10093 * src/output.c (token_definitions_output,
10094 symbol_destructors_output, symbol_destructors_output): Use string,
10095 not boolean integer, to keep track of whether to output separator.

10101 2003-05-14 Paul Eggert <eggert@twinsun.com>
10103 * src/parse-gram.y (rules_or_grammar_declaration): Require a
10104 semicolon after a grammar declaration, in the interest of possible
10105 future changes to the Bison input language.
10106 Do not allow a stray semicolon at the start of the grammar.
10107 (rhses.1): Allow one or more semicolons after any rule, including
10108 just before "|" as required by POSIX.
10109 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
10112 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
10114 %parse-param support for lalr1.cc.
10116 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
10117 b4_cc_constructor_calls, b4_cc_constructor_call,
10118 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
10120 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
10121 parse-param arguments.
10122 (yy::b4_parser_class_name): Declare instance variables to
10123 hold parse-param arguments.
10124 * tests/calc.at: s/value/semantic_value/ because value clashes
10125 with a member of yy::b4_parser_class_name. Adjust C++ code
10126 to handle %parse-param. Enable %parse-param test in C++.
10128 2003-05-12 Paul Eggert <eggert@twinsun.com>
10130 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
10131 English a bit. Fix fclose typo. Change "const char" to "char
10132 const", and use ANSI C rather than K&R for "main". Suggest
10133 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
10134 and suggest yy_switch_to_buffer.
10136 2003-05-05 Paul Eggert <eggert@twinsun.com>
10138 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
10139 C89. This avoids a diagnostic on compilers that define __STDC__
10140 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
10141 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10143 2003-05-03 Paul Eggert <eggert@twinsun.com>
10145 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
10146 Do not overrun array bounds.
10147 This should fix a bug reported today by Olatunji Oluwabukunmi in
10148 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
10150 2003-04-29 Akim Demaille <akim@epita.fr>
10152 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
10153 * src/getargs.c, src/getargs.h: here, as bool, not int.
10154 (nondeterministic_parser): New.
10155 * src/parse-gram.y, src/scan-gram.l: Support
10156 %nondeterministic-parser.
10157 * src/output.c (prepare): Use nondeterministic_parser instead
10158 of glr_parser where appropriate.
10159 * src/tables.c (conflict_row, action_row, save_row)
10160 (token_actions, token_actions, pack_vector): Ditto.
10162 2003-04-29 Akim Demaille <akim@epita.fr>
10164 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
10166 2003-04-29 Akim Demaille <akim@epita.fr>
10168 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
10169 with %pure-parser and %locations to exercise the patch from Yakov
10172 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
10174 * data/yacc.c: (b4_lex_param): Corrected for the case where
10175 %lex-param is provided and %pure-parser isn't.
10177 2003-04-27 Paul Eggert <eggert@twinsun.com>
10179 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
10180 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
10181 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
10182 if it is not defined.
10183 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
10185 2003-04-26 Paul Eggert <eggert@twinsun.com>
10187 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
10188 Declare to be of type suitable for the ninf value itself, not of
10189 type suitable for the corresponding table, since the latter might
10190 be unsigned but the ninf value might be negative. This fixes a
10191 bug reported by Alexandre Duret-Lutz in
10192 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
10194 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
10195 invokes it. We shouldn't invoke it twice because it will attempt
10196 to put error.o in the archive twice. This fixes a glitch reported
10197 by Martin Mokrejs in
10198 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10200 2003-04-21 Paul Eggert <eggert@twinsun.com>
10202 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
10205 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
10207 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
10208 Fix obvious typo that results in uncompilable GLR parsers
10209 when both %pure-parser and %locations are used. (trivial change)
10211 2003-04-17 Paul Eggert <eggert@twinsun.com>
10213 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
10214 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
10215 Do not insert the expected token via unput, as this runs afoul
10216 of a POSIX-compatibility bug in flex 2.5.31.
10217 All uses changed to BEGIN the parent state,
10218 since we no longer insert the expected token via unput.
10219 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
10220 that is no longer emitted after the above change.
10222 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
10223 the first one. This change is from Paul Hilfinger, and it fixes
10224 regression reported by Werner Lemberg in
10225 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
10227 (resolve_sr_conflict): Don't invoke state_errs_set
10228 unless one or more tokens have been explicitly made errors.
10229 Otherwise, the above change causes Bison to abort.
10231 * tests/existing.at (GNU pic Grammar): New test case, taken from
10234 2003-03-31 Akim Demaille <akim@epita.fr>
10236 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
10238 2003-03-31 Akim Demaille <akim@epita.fr>
10240 * src/output.c (prepare_symbols): Avoid trailing spaces in the
10243 2003-03-31 Akim Demaille <akim@epita.fr>
10245 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
10246 From Paul Hilfinger.
10248 2003-03-29 Akim Demaille <akim@epita.fr>
10250 * m4/error.m4: Do not put under dynamic conditions some code which
10251 expansion is under static control.
10253 2003-03-29 Akim Demaille <akim@epita.fr>
10255 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
10257 2003-03-29 Akim Demaille <akim@epita.fr>
10259 * doc/bison.texinfo (Strings are Destroyed): New.
10261 2003-03-13 Paul Eggert <eggert@twinsun.com>
10263 * .cvsignore: Add configure.lineno.
10264 * src/.cvsignore: Add yacc.
10265 * tests/.cvsignore: Add testsuite.log.
10266 * doc/fdl.texi: Sync with latest FSF version.
10268 2003-03-12 Paul Eggert <eggert@twinsun.com>
10270 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
10271 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
10272 cursor, instead of leaving it undefined. This fixes a bug
10273 reported by Tim Van Holder in
10274 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
10275 * tests/input.at (Torturing the Scanner): Test the scanner on
10276 an empty input file, which was Tim Van Holder's test case.
10278 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
10279 <sys/resource.h> can be included, include sys/time.h and
10280 sys/times.h first, if available. This works around the SunOS
10281 4.1.4 porting bug reported by Bruce Becker in
10282 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
10284 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
10285 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
10286 AC_HEADER_SYS_WAIT.
10288 Merge changes from gnulib. This was prompted because the CVS
10289 snapshot didn't build on Solaris 7 due to strnlen problems.
10291 These changes need to be merged back into gnulib:
10292 * lib/hash.c: Include <stdbool.h> unconditionally.
10293 * m4/onceonly.m4 (m4_quote): New macro.
10294 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
10295 Quote AC_FOREACH variable-expansions properly.
10296 The 2003-01-03 obstack.h change also needs merging.
10297 {end of changes requiring merging}
10299 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
10300 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
10301 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
10302 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
10303 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
10304 New files, imported from gnulib.
10305 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
10308 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
10309 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
10312 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
10314 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
10315 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
10316 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
10317 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
10318 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
10319 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
10320 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
10321 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
10322 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
10323 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
10324 (jm_PREREQ_ARGMATCH): Remove.
10325 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
10326 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
10328 * src/system.h: Include <stdbool.h> unconditionally.
10330 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
10331 assuming at least C89 in the bitset code for some time now.
10333 2003-03-03 Akim Demaille <akim@epita.fr>
10337 2003-03-02 Akim Demaille <akim@epita.fr>
10339 * doc/bison.texinfo (Table of Symbols): Reactivate the
10340 documentation for %lex-param, and %parse-param.
10342 2003-03-02 Akim Demaille <akim@epita.fr>
10344 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
10345 generate verbose error messages.
10346 Use the number of tokens as an upper bound in yytname, as it
10347 cannot be a non terminal.
10349 2003-03-02 Akim Demaille <akim@epita.fr>
10351 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
10354 2003-03-02 Akim Demaille <akim@epita.fr>
10356 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
10357 Use them to exercise yycheck overrun.
10358 Based on Andrew Suffield's grammar.
10360 2003-03-02 Akim Demaille <akim@epita.fr>
10362 Create tests/local.at for Bison generic testing macros.
10364 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
10365 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
10367 * tests/calc.at (AT_CHECK_CALC): Adjust.
10368 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
10369 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
10370 * tests/local.at: here.
10371 (AT_COMPILE_CXX): Tags the tests using it as c++.
10372 Ignore the test if CXX is not functional.
10374 2003-03-01 Paul Eggert <eggert@twinsun.com>
10376 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
10377 not loc->end, since loc->end might contain garbage and this leads
10378 to undefined behavior on some platforms.
10379 (id_loc, token_start): Use (IF_LINTed) initial values that do not
10380 depend on *loc, so that the reader doesn't give the the false
10381 impression that *loc is initialized.
10382 (<INITIAL>"%%"): Do not bother setting code_start, since its value
10383 does not survive the return.
10385 2003-03-01 Akim Demaille <akim@epita.fr>
10387 * src/scan-gram.l (code_start): Always initialize it when entering
10388 into yylex, as SC_EPILOGUE is activated *before* the corresponding
10389 yylex invocation. An alternative would be making it static, but
10390 then it starts with the second %%'s beginning, instead of its end.
10392 2003-02-28 Paul Eggert <eggert@twinsun.com>
10394 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
10395 around a UnixWare 7.1.1 porting bug reported by John Hughes in
10396 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
10398 2003-02-26 Paul Eggert <eggert@twinsun.com>
10400 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
10401 Remove Sequent/Pyramid discussion (nobody uses them any more).
10402 Merge VMS and MS-DOS discussion; these ports may well be dead
10403 but let's keep mentioning them for now. Put <> around email
10404 addresses. Add copyright notice.
10406 2003-02-24 Paul Eggert <eggert@twinsun.com>
10408 * data/glr.c (yy_reduce_print): yylineno -> yylno,
10409 to avoid collision with flex use of yylineno.
10410 Problem reported by Bruce Lilly in
10411 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
10412 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
10413 * data/yacc.c (yy_reduce_print): Likewise.
10415 * config/depcomp: Sync with Automake 1.7.3.
10417 2003-02-21 Akim Demaille <akim@epita.fr>
10419 * data/lalr1.cc: Use temporary variables instead of casts to
10420 change integer types.
10421 Suggested by Paul Eggert.
10423 2003-02-21 Akim Demaille <akim@epita.fr>
10425 * doc/bison.texinfo: Use "location" consistently to refer to @n,
10426 to avoid confusions with lalr1.cc's notion of Position.
10427 Suggested by Paul Eggert.
10429 2003-02-20 Akim Demaille <akim@epita.fr>
10431 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
10432 before initial_columns.
10433 (location.hh): Use consistent variable names when defining the
10435 Use "last" so that we subtract from Positions, not from unsigned.
10437 2003-02-20 Akim Demaille <akim@epita.fr>
10439 * data/lalr1.cc (position.hh): New subfile, including the extended
10440 and Doxygen'ed documentation of class Position.
10441 (location.hh): Use it.
10442 Document a` la Doxygen.
10443 With the help of Benoit Perrot.
10445 2003-02-20 Akim Demaille <akim@epita.fr>
10447 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
10449 Redefine AT_YYERROR_SEES_LOC_IF using it.
10450 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
10452 Don't use the location in yy::Parser::error_ and
10453 yy::Parser::print_ when not %locations.
10454 Activate more lalr1.cc tests.
10456 2003-02-19 Akim Demaille <akim@epita.fr>
10458 * data/lalr1.cc: When displaying a line number, be sure to make it
10461 2003-02-19 Akim Demaille <akim@epita.fr>
10463 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
10465 (YYABORT, YYACCEPT, YYERROR): New.
10466 * tests/calc.at: Renable the lalr1.cc test.
10468 2003-02-19 Akim Demaille <akim@epita.fr>
10470 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
10471 error recovery, mixing with/without pops and discarding of the
10474 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
10476 2003-02-17 Paul Eggert <eggert@twinsun.com>
10478 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
10479 * tests/testsuite.at (AT_COMPILE): Use them.
10480 This fixes the testsuite problem reported by Robert Lentz in
10481 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
10483 2003-02-12 Paul Eggert <eggert@twinsun.com>
10485 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
10486 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
10487 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
10488 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
10489 Check for malloc failure, for consistency with yacc.c.
10490 (yytname_size): Remove, for consistency with yacc.c.
10492 The bug still remains in data/lalr1.cc, as I didn't have time
10495 2003-02-06 Akim Demaille <akim@epita.fr>
10497 * configure.ac (GXX): Rename as...
10498 (CXX): this, to keep the original Autoconf semantics.
10500 * data/lalr1.cc: Fix b4_copyright invocations.
10501 If YYDEBUG is not defined, don't depend upon name_ being defined.
10502 (location.hh): Include string and iostream.
10503 (Position::filename): New member.
10504 (Position::Position ()): New.
10505 (operator<< (Position)): New.
10506 (operator- (Position, int)): New.
10507 (Location::first, Location::last): Rename as...
10508 (Location::begin, Location::end): these, to mock the conventional
10510 (operator<< (Location)): New.
10511 * tests/atlocal.in (CXX): New.
10512 * tests/testsuite.at (AT_COMPILE_CXX): New.
10513 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
10514 locations in a more synthetic way.
10515 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
10517 Adjust the C locations to match those from Emacs: first column is
10519 Change all the expected results.
10520 Conform to the GCS: simplify the locations when applicable.
10521 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
10522 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
10523 these CPP macros with the m4 macros new defined by...
10524 (AT_CHECK_PUSHDEFS): this, i.e.:
10525 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
10526 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
10528 (AT_CHECK_POPDEFS): Undefine them.
10529 (AT_CHECK_CALC_LALR1_CC): New.
10530 Use it for the first lalr1.cc test.
10532 2003-02-04 Akim Demaille <akim@epita.fr>
10534 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
10535 Location as is defined.
10537 2003-02-04 Akim Demaille <akim@epita.fr>
10539 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
10540 name_ being defined.
10542 2003-02-03 Paul Eggert <eggert@twinsun.com>
10544 * src/gram.h (start_symbol): Remove unused decl.
10546 Use more-consistent naming conventions for local vars.
10548 * src/derives.c (derives_compute): Change type of local var from
10549 int to rule_number.
10550 * src/gram.c (grammar_rules_partial_print): Likewise.
10551 * src/print.c (print_core): Likewise.
10552 * src/reduce.c (reduce_grammar_tables): Likewise.
10554 * src/gram.c (grammar_dump): Change name of item_number *
10555 local var from r to rp.
10556 * src/nullable.c (nullable_compute): Likewise.
10558 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
10560 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
10561 for symbol or symbol_number var.
10562 * src/reader.c (grammar_start_symbol_set): Likewise.
10563 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
10565 * src/state.c (transitions_to): Likewise.
10566 * src/state.h: Likewise.
10567 * src/tables.c (symbol_number_to_vector_number): Likewise.
10569 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
10572 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
10575 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
10578 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
10579 Use str, not s, for char * var. Use ch, not c, for character var.
10580 Use size for size var.
10582 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
10584 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
10586 * src/uniqstr.h: Likewise.
10588 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
10589 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
10590 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
10591 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
10592 param to have same name as that of enum, so that we don't use
10593 "s" to stand for a non-state.
10595 2003-02-02 Akim Demaille <akim@epita.fr>
10597 * src/scan-skel.l: Scan more than one inert character per yylex
10600 2003-02-01 Paul Eggert <eggert@twinsun.com>
10604 * po/LINGUAS: Add ms.
10606 2003-01-30 Akim Demaille <akim@epita.fr>
10608 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
10610 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10612 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
10615 Changes in response to error report by S. Eken: GLR mode does not
10616 handle negative $ indices or $ indices in embedded rules correctly.
10617 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
10619 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
10620 (b4_rhs_location): Ditto.
10621 (yyfill): New function to copy from stack tree into array
10623 (yyuserAction): Modify to allow incremental move of semantic values
10624 to rhs array when in GLR mode.
10625 Define YYFILL to use in user-defined actions to fill semantic array
10627 Remove dummy use of yystack, as there is now a guaranteed use.
10628 (yydoAction): Modify to allow incremental move of semantic values
10629 to rhs array when in GLR mode.
10630 (yyresolveAction): Ditto.
10631 (yyglrShiftDefer): Update comment.
10632 (yyresolveStates): Use X == NULL for pointers, not !X.
10633 (yyglrReduce): Ditto.
10634 (yydoAction): Ditto
10636 * tests/glr-regr1.at: Rename to ...
10637 * tests/glr-regression.at: Add new regression test for the problems
10638 described above (adapted from S. Eken).
10639 Update copyright notice.
10640 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
10641 * tests/Makefile.am: Ditto.
10643 2003-01-28 Paul Eggert <eggert@twinsun.com>
10645 * data/lalr1.cc: Do not use @output_header_name@ unless
10646 b4_defines_flag is set. This fixes two bugs reported by
10648 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
10649 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
10651 2003-01-21 Paul Eggert <eggert@twinsun.com>
10653 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
10654 we don't need to worry about yyerrlab1 being reported as an
10655 "unused label" by non-GCC C compilers. The downside is that if
10656 locations are used then a couple of statements are duplicated each
10657 time YYERROR is invoked, but the upside is that the warnings
10659 (yyerrlab1): Move code to YERROR.
10660 (yyerrlab2): Remove. Change uses back to yyerrlab1.
10661 This reverts some of the 2002-12-27 change.
10663 2003-01-17 Paul Eggert <eggert@twinsun.com>
10665 * src/output.c (symbol_printers_output): Fix typo that led
10666 to core dump. Problem reported by Antonio Rus in
10667 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
10669 2003-01-13 Akim Demaille <akim@epita.fr>,
10670 Quoc Peyrot <chojin@lrde.epita.fr>,
10671 Robert Anisko <anisko_r@lrde.epita.fr>
10673 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
10674 when the stacks contain one element, as the loop would otherwise
10675 free the last state, and then use the top state (the one we just
10676 popped). This means that the initial elements will not be freed
10677 explicitly, as is the case in yacc.c; it is not a problem, as
10678 these elements have fake values.
10680 2003-01-11 Paul Eggert <eggert@twinsun.com>
10682 * NEWS: %expect-violations are now just warnings, reverting
10683 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
10684 bootstrapping problem reported by Matthias Klose; see
10685 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
10686 * src/conflicts.c (conflicts_print): Likewise.
10687 * tests/conflicts.at (%expect not enough, %expect too much,
10688 %expect with reduce conflicts): Likewise.
10689 * doc/bison.texinfo (Expect Decl): Document this. Also mention
10690 that the warning is enabled if the number of conflicts changes
10691 (not necessarily increases).
10693 * src/getargs.c (version): Update copyright year.
10695 2003-01-09 Akim Demaille <akim@epita.fr>
10697 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
10699 2003-01-08 Paul Eggert <eggert@twinsun.com>
10701 * Makefile.maint (WGETFLAGS):
10702 New macro, containing "-C off" to disable proxy caches.
10703 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
10704 (rel-check): Use $(WGET) instead of wget.
10706 2003-01-06 Paul Eggert <eggert@twinsun.com>
10708 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
10709 the GLR paper of Scott, Johnstone and Hussain.
10711 2003-01-04 Paul Eggert <eggert@twinsun.com>
10713 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
10714 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
10715 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
10716 (EXTRA_LIBRARIES): New var, for liby.a.
10717 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
10718 (EXTRA_SCRIPTS): New var, for yacc.
10720 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
10721 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
10722 Problem reported by Nelson H. F. Beebe.
10724 2003-01-03 Paul Eggert <eggert@twinsun.com>
10726 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
10727 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
10728 when compiling Bison 1.875's `bitset bset = obstack_alloc
10729 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
10731 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
10732 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
10733 grow to a huge size with typical invocation.
10735 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
10736 Use the pattern recommended by Autoconf 2.57, except also protect
10737 against double-definition.
10738 * src/system.h: Likewise.
10739 Portability issues reported by Nelson H. F. Beebe.
10741 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
10742 All uses changed. Provide a definition in both C and C++.
10743 (yytrue, yyfalse): Define even if defined (__cplusplus).
10745 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
10746 Reported by Nelson H. F. Beebe.
10748 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
10750 2003-01-02 Paul Eggert <eggert@twinsun.com>
10752 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
10753 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
10754 Bug reported by Nelson H. F. Beebe.
10756 2003-01-01 Paul Eggert <eggert@twinsun.com>
10760 2002-12-30 Paul Eggert <eggert@twinsun.com>
10762 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
10764 (<INITIAL>","): Here. This causes stray "," to be treated
10767 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
10768 last brace in braced code when not in Yacc mode, for compatibility
10769 with Bison 1.35. This resurrects the 2001-12-15 patch to
10772 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
10773 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
10775 2002-12-28 Paul Eggert <eggert@twinsun.com>
10777 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
10778 that of SYM's type. This fixes Debian bug 168069, reported by
10781 2002-12-28 Paul Eggert <eggert@twinsun.com>
10785 Switch back to the Yacc style of conflict reports, undoing some
10786 of the 2002-07-30 change.
10787 * doc/bison.texinfo (Understanding): Use Yacc style for
10788 conflict reports. Also, use new way of locating rules.
10789 * src/conflicts.c (conflict_report):
10790 Renamed from conflict_report_yacc, removing the old
10791 'conflict_report'. Translate the entire conflict report at once,
10792 so that we don't assume that "," has the same interpretation in
10794 (conflicts_output): Use Yacc-style conflict report for each state,
10795 instead of our more-complicated style.
10796 (conflicts_print): Use Yacc-style conflict report, except print
10797 the input file name when not emulating Yacc.
10798 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
10799 Conflicted Reduction, %expect not enough, %expect too much,
10800 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
10801 * tests/existing.at (GNU Cim Grammar): Likewise.
10802 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
10804 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
10805 fatal): Don't invoke fflush; it's not needed and it might even be
10806 harmful for stdout, as stdout might not be open.
10807 * src/reduce.c (reduce_print): Likewise.
10809 2002-12-27 Paul Eggert <eggert@twinsun.com>
10811 Fix a bug where error locations were not being recorded correctly.
10812 This problem was originally reported by Paul Hilfinger in
10813 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
10815 * data/yacc.c (yyparse): New local var yylerrsp, to record the
10816 top of the location stack's error locations.
10817 (yyerrlab): Set it. When discarding a token, push its location
10818 onto yylerrsp so that we don't lose track of the error's end.
10819 (yyerrlab1): Now is only the target of YYERROR, so that we can
10820 properly record the location of the action that failed. For GCC
10821 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
10822 GCC warning about yyerrlab1 being unused if YYERROR is unused.
10823 (yyerrlab2): New label, which yyerrlab now falls through to.
10824 Compute the error's location by applying YYLLOC_DEFAULT to
10825 the locations of all the symbols that went into the error.
10826 * doc/bison.texinfo (Location Default Action): Mention that
10827 YYLLOC_DEFAULT is also invoked for syntax errors.
10828 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10829 Error locations include the locations of all the tokens that were
10830 discarded, not just the last token.
10832 2002-12-26 Paul Eggert <eggert@twinsun.com>
10834 * src/files.c: Include quote.h.
10835 (compute_output_file_names): Warn if we detect conflicting
10836 outputs to the same file. This should catch the misunderstanding
10837 exemplified by Debian Bug 165349, reported by Bruce Stephens..
10839 * src/conflicts.c (conflicts_print): If the user specifies
10840 "%expect N", report an error if there are any reduce/reduce
10841 conflicts. This is what the manual says should happen.
10842 This fixes Debian bug 130890, reported by Anthony DeRobertis.
10843 * tests/conflicts.at (%expect with reduce conflicts): New test.
10845 Don't use m4_include on relative file names, as it doesn't work as
10846 desired if there happens to be a file with that name under ".".
10848 * m4sugar/version.m4: Remove; it was included but it wasn't used.
10849 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
10850 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
10851 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
10852 * src/output.c (output_skeleton): Use full path names when
10853 specifying a file to include; don't rely on include path, as
10854 it's unreliable when the working file contains a file with
10857 2002-12-25 Paul Eggert <eggert@twinsun.com>
10859 Remove obsolete references to bison.simple and bison.hairy.
10860 Problem mentioned by Aubin Mahe in
10861 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
10862 * data/glr.c: Comment fix.
10863 * doc/bison.1: Remove references. Also, mention "yacc".
10865 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
10868 * src/parse-gram.y (declaration): Use enum "report_states" rather
10869 than its numeric value 1.
10871 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
10872 opening a new one. This fixes Debian bug 165349, reported by
10875 2002-12-24 Paul Eggert <eggert@twinsun.com>
10879 * Makefile.maint (cvs-update): Don't assume that the shell
10880 supports $(...), as Solaris sh doesn't.
10882 * src/parse-gram.y (lloc_default): Remove test for empty
10883 nonterminals at the end, since it didn't change the result.
10885 2002-12-24 Paul Eggert <eggert@twinsun.com>
10887 If the user does not define YYSTYPE as a macro, Bison now declares it
10888 using typedef instead of defining it as a macro. POSIX requires this.
10889 For consistency, YYLTYPE is also declared instead of defined.
10891 %union directives can now have a tag before the `{', e.g., the
10892 directive `%union foo {...}' now generates the C code
10893 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
10894 The default union tag is `YYSTYPE', for compatibility with Solaris 9
10895 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
10896 instead of `yyltype'.
10898 `yystype' and `yyltype' are now obsolescent macros instead of being
10899 typedefs or tags; they are no longer documented and will be
10900 withdrawn in a future release.
10902 * data/glr.c (b4_location_type): Remove.
10903 (YYSTYPE): Renamed from yystype.
10904 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
10905 (struct YYLTYPE): Renamed from struct yyltype.
10906 (YYLTYPE): Renamed from yyltype.
10907 (yyltype, yystype): New (and obsolescent) macros,
10908 for backward compatibility.
10909 * data/yacc.c: Likewise.
10911 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
10912 does not specify a union tag. This is for compatibility with
10915 * src/parse-gram.y (add_param): 2nd arg is now char * not char
10916 const *, since it is now modified by stripping surrounding { }.
10917 (current_braced_code): Remove.
10918 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
10919 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
10920 trailing " {...}". Now of type <chars>.
10921 (grammar_declaration): Adjust to bundled tokens.
10922 (code_content): Remove; stripping is now done by add_param.
10923 (print_token_value): Print contents of bundled tokens.
10924 (token_name): New function.
10926 * src/reader.h (braced_code, current_braced_code): Remove.
10927 (token_name): New decl.
10929 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
10930 token_type, not braced_code code_kind. All uses changed.
10931 (SC_PRE_CODE): New state, for scanning after a keyword that
10932 has (or usually has) an immediately-following braced code.
10933 (token_type): New local var, to keep track of which token type
10934 to return when scanning braced code.
10935 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
10936 <INITIAL>"%parse-param", <INITIAL>"%printer",
10937 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
10938 instead of returning a token type immediately.
10939 (<INITIAL>"{"): Set token type.
10940 (<SC_BRACED_CODE>"}"): Use it.
10941 (handle_action_dollar, handle_action_at): Now returns bool
10942 indicating success. Fail if ! current_rule; this prevents a core dump.
10943 (handle_symbol_code_dollar, handle_symbol_code_at):
10944 Remove; merge body into caller.
10945 (handle_dollar, handle_at): Complain in invalid contexts.
10947 * NEWS, doc/bison.texinfo: Document the above.
10948 * NEWS: Fix years and program names in copyright notice.
10950 2002-12-17 Paul Eggert <eggert@twinsun.com>
10952 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
10953 Reporting, Table of Symbols): Omit mentions of %lex-param and
10954 %parse-param from the documentation for now.
10956 2002-12-15 Paul Eggert <eggert@twinsun.com>
10958 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
10959 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
10960 lookahead symbol, and which sets yychar in parser actions) and it
10961 disagreed with the Bison documentation. Bug
10962 reported by Andrew Walrond.
10964 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
10965 as the caller now does that.
10966 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
10967 (YYEMPTY): Parenthesize right hand side, since others use it.
10968 (yyparse): Don't assume that our generated code is the only code
10971 2002-12-13 Paul Eggert <eggert@twinsun.com>
10975 POSIX requires a "yacc" command.
10976 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
10977 (MOSTLYCLEANFILES): Add yacc.
10979 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
10980 as an alias for bison y.
10982 * po/LINGUAS: Add da.
10984 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
10985 problem with latest <getopt.h>.
10986 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
10988 * doc/fdl.texi: Upgrade to 1.2.
10989 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
10990 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
10991 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
10993 * config/install-sh: Sync with autotools.
10995 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
10996 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
10997 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
10998 locations are requested.
10999 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
11000 locations are requested.
11002 2002-12-12 Paul Eggert <eggert@twinsun.com>
11004 Remove unportable casts and storage allocation tricks.
11005 While we're at it, remove almost all casts, since they
11006 usually aren't needed and are a sign of trouble.
11008 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
11010 * src/derives.c (derives_compute): Do not subtract NTOKENS from
11011 the pointer DSET returned by malloc; this isn't portable.
11012 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
11013 Similarly for DERIVES.
11014 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
11015 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
11016 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
11018 * src/derives.c (derives_compute): Do not bother invoking

11030 * src/state.h (state_number_as_int): Likewise.
11031 * src/tables.c (state_number_to_vector_number,
11032 symbol_number_to_vector_number): Likewise.
11034 * src/gram.h (int_of_rule_number): Remove; no longer used.
11036 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,

11039 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
11042 * src/muscle_tab.c (muscle_m4_output):
11043 Now inline. Return bool, not int.
11044 * src/state.c (state_compare): Likewise.
11045 * src/symtab.c (symbol_check_defined,
11046 symbol_check_alias_consistency, symbol_pack, symbol_translation,

11054 symbol_check_alias_consistency_processor, symbol_pack_processor,
11055 symbol_translation_processor, hash_symbol_comparator,
11056 hash_symbol_hasher): Likewise.
11057 * src/uniqstr.c (uniqstr_print_processor): Likewise.
11058 * src/muscle_tab.c (muscles_m4_output):
11059 Use new functions instead of casting old functions unportably.
11060 * src/state.c (state_hash_new): Likewise.
11061 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
11062 symbols_token_translations_init):
11064 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
11066 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
11067 var instead of casting to long, to avoid casts.
11068 (prepare_states): Use MALLOC rather than alloca, so that we don't
11069 have to worry about alloca.
11070 * src/state.c (state_hash_lookup): Likewise.
11072 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
11073 local var instead of casting to unsigned char, to avoid casts.
11075 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
11076 STATE_ALLOC): Remove.
11077 (transitions_new, errs_new, reductions_new, state_new): Use malloc
11078 rather than calloc, and use offsetof to avoid allocating slightly
11080 (state_new): Initialize all members.
11082 * src/state.c (state_hash): Use unsigned accumulator, not signed.
11084 * src/symtab.c (symbol_free): Remove; unused.
11085 (symbol_get): Remove cast in lhs of assignment.
11086 (symbols_do): Now static. Accept generic arguments, not
11087 hashing-related ones.
11089 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
11090 (symbol_processor): Remove.
11091 (symbols_do): Remove decl; now static.
11093 * src/system.h (alloca): Remove; decl no longer needed.
11094 (<stddef.h>): Include, for offsetof.
11095 (<inttypes.>, <stdint.h>): Include if available.
11096 (uintptr_t): New type, if system lacks it.
11097 (CALLOC, MALLOC, REALLOC): New macros.
11098 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
11101 * src/tables.c (table_size): Now int, to pacify GCC.
11102 (table_grow, table_ninf_remap): Use signed table size.
11103 (save_row): Don't bother initializing locals when not needed.

11114 2002-12-09 Paul Eggert <eggert@twinsun.com>
11116 Change identifier spellings to avoid collisions with names
11117 that are reserved by POSIX.
11119 Don't use names ending in _t, since POSIX reserves them.
11120 For consistency, remove _e and _s endings -- they're weren't
11121 needed to remove ambiguity. All uses changed.
11122 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
11123 turn was just renamed from struniq_t.
11124 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
11125 which in turn was just renamed from struniq_processor_t.
11126 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
11127 in turn was renamed from hash_compare_struniq_t.

11197 value_t_as_yystype -> value_as_yystype.
11199 Don't include <errno.h> in the mainstream code, since it
11200 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
11201 * lib/get-errno.c, lib/get-errno.h: New files.
11202 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
11204 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.

11212 (TAB_EXT): Renamed from EXT_TAB.
11213 (OUTPUT_EXT): Renamed from EXT_OUTPUT.

11217 likewise for "STRUNIQ" and "UNIQSTR".
11218 * src/uniqstr.c: Renamed from src/struniq.c.
11219 * src/uniqstr.h: Renamed from src/struniq.h.
11220 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

11223 * src/files.h (strsuffix, stringappend): Remove; unused.
11224 * src/parse-gram.y (<chars>): Renamed from <string>.
11225 (<uniqstr>): Renamed from <struniq>.

11230 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
11231 (N_EXPAND): Renamed from N_STRETCH.

11240 * src/tables.c (VECTOR_NUMBER_MAX, VECTOR_NUMBER_MIN): Remove; unused.
11241 (BASE_MAXIMUM): Renamed from BASE_MAX.
11242 (BASE_MINIMUM): Renamed from BASE_MIN.
11243 (ACTION_MAX): Remove; unused.
11244 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
11245 Unnecessary casts removed from above defines.

11249 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
11250 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from

11257 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
11260 Sort include-file uses.
11262 Reorder all include files under src to be in the order "system.h".
11263 then the ../lib include files in angle brackets (alphabetized),
11264 then the . include files in double-quotes (alphabetized). Fix
11265 dependency breakages encountered in this process, as follows:
11266 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
11267 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
11268 * src/state.h: Include "symtab.h".
11270 2002-12-08 Paul Eggert <eggert@twinsun.com>
11272 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
11273 since this causes problems when __file__ contains character
11274 sequences like "@" that are treated specially by src/scan-skel.l.
11275 Instead, just use the file's basename. This fixes the bug
11276 reported by Martin Mokrejs in
11277 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
11279 2002-12-06 Paul Eggert <eggert@twinsun.com>
11281 Add support for rules that do not have trailing semicolons, as

11285 * src/location.c: Include <quotearg.h>.
11286 (empty_location): Now const.
11287 (location_print): New function. Follow the recommendation of the
11288 GNU Coding Standards for locations that span file boundaries.
11289 * src/location.h: Do not include <quotearg.h>; no longer needed.
11290 (boundary): New type.
11291 (location_t): Use it. This allows locations to span file boundaries.
11292 All member uses changed: file -> start.file or end.file (as needed),
11293 first_line -> start.line, first_column -> start.column,
11294 last_line -> end.line, last_column -> end.column.
11295 (equal_boundaries): New function.
11296 (LOCATION_RESET, LOCATION_STEP): Remove.
11297 (LOCATION_PRINT): Remove. All callers changed to use location_print.
11298 (empty_location): Now const.
11299 (location_print): New decl.
11300 * src/parse-gram.y (lloc_default): New function, which handles
11301 empty locations more accurately.
11302 (YYLLOC_DEFAULT): Use it.
11303 (%token COLON): Remove.
11304 (%token ID_COLON): New token.
11306 (declarations, rules): Remove trailing semicolon.
11307 (declaration, rules_or_grammar_declaration):

11310 (rules_or_grammar_declaration): Remove trailing semicolon.
11311 (semi_colon.opt): Remove.
11312 * src/reader.h: Include location.h.
11313 (scanner_cursor): New decl.
11314 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
11316 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
11318 (STEP): Remove. No longer needed, now that adjust_location does
11319 the work. All uses removed.
11320 (scanner_cursor): New var.
11321 (adjust_location): Renamed from extend_location. It now sets
11322 *loc and adjusts the scanner cursor. All uses changed.
11323 Don't bother testing for CR.
11324 (handle_syncline): Remove location arg; now updates scanner cursor.
11325 All callers changed.
11326 (unexpected_end_of_file): Now accepts start boundary of token or
11327 comment, not location. All callers changed. Update scanner cursor,
11329 (SC_AFTER_IDENTIFIER): New state.
11330 (context_state): Renamed from c_context. All uses changed.
11331 (id_loc, code_start, token_start): New local vars.
11332 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
11333 processing of Yacc white space and equivalents here.
11334 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
11335 instead of returning ID immediately, since we need to search for
11336 a subsequent colon.
11337 (<INITIAL>"'", "\""): Save token_start.
11338 (<INITIAL>"%{", "{", "%%"): Save code_start.
11339 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
11340 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
11341 BEGIN context_state at end, not INITIAL.
11342 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
11343 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
11344 Return correct token start.
11345 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
11346 the start of a character, string or multiline comment is found.
11347 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
11348 Reduction): Adjust reported locations to match the more-precise
11349 results now expected.
11350 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
11351 * tests/reduce.at (Useless Rules, Reduced Automaton,
11352 Underivable Rules): Likewise.
11353 * tests/regression.at (Invalid inputs): No longer `expecting ";"
11354 or "|"' now that so many other tokens are allowed by the new grammar.
11356 * src/complain.h (current_file): Remove duplicate decl;
11357 current_file is now owned by files.h.
11358 * src/complain.c, src/scan-gram.l: Include files.h.
11360 2002-12-06 Paul Eggert <eggert@twinsun.com>
11362 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
11363 promotes to int; it might be unsigned int.
11364 * data/yacc.c (yy_reduce_print): Likewise.
11366 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
11367 be #defined in the prologue, not in the Bison declarations.
11368 This fixes Debian Bug 102878, reported by Shaul Karl.
11370 2002-12-02 Paul Eggert <eggert@twinsun.com>
11372 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
11373 * lib/strtoul.c: New file, from gnulib.
11374 This fixes a porting bug reported by Peter Klein in
11375 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
11377 2002-11-30 Paul Eggert <eggert@twinsun.com>
11379 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
11380 and put only a forward declaration in the prologue. This is for
11381 consistency with the other scanner helper functions.
11383 Type clashes now generate warnings, not errors, since it
11384 appears that POSIX may allow some grammars with type clashes.
11385 * src/reader.c (grammar_current_rule_check): Warn about
11386 type clashes instead of complaining.
11387 * tests/input.at (Type Clashes): Expect warnings, not complaints.
11389 Add Yacc library, since POSIX requires it.
11390 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
11391 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
11392 * lib/main.c, lib/yyerror.c: New files.
11394 gram_error can be static; it need not be extern.
11395 * src/reader.h (gram_error): Remove decl.
11396 * src/parse-gram.y (gram_error): Now static. Add static decl.
11397 (print_token_value): Omit parameter names from forward decl,
11400 2002-11-29 Paul Eggert <eggert@twinsun.com>
11402 * doc/bison.texinfo: Emphasize that yylex and yyerror must
11403 be declared before being used. E.g., one should typically
11404 declare them in the prologue. Use GNU coding style in examples.
11405 Put "const" consistently after the type it modifies. Mention
11406 that C99 supports "inline". Mention that yyerror traditionally
11409 %parse-param and %lex-param now take just one argument, the
11410 declaration; the argument name is deduced from the declaration.
11412 * doc/bison.texinfo (Parser Function, Pure Calling, Error
11413 Reporting, Table of Symbols): Document this.
11414 * src/parse-gram.y (add_param): New function.
11416 (declaration): Implement new rule for %parse-param and %lex-param.
11417 * src/scan-gram.l: "," now elicits a warning, rather than being
11418 a token; this is more compatible with byacc.
11419 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
11421 2002-11-27 Paul Eggert <eggert@twinsun.com>
11423 Rename identifiers to avoid real and potential collisions.
11425 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
11426 to avoid collision with lex macro described by Bruce Lilly in
11427 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
11428 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
11429 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
11430 * src/parse-gram.y (print_token_value): Renamed from yyprint.
11432 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
11433 The name "yycontrol" violates the name space rules, and this stuff
11434 wasn't being used anyway.
11435 (input): Remove action; this stuff wasn't being used.
11436 (gram_error): Rename local variable yylloc -> loc.
11437 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
11438 (YY_DECL): Don't use "yy" at start of local variables.
11439 All uses changed, e.g., yylloc -> loc.
11440 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
11441 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
11442 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
11443 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
11445 * src/parse-gram.y (gram_error): loc is now const *.
11446 * src/reader.h (gram_error): Likewise.
11448 2002-11-24 Paul Eggert <eggert@twinsun.com>
11452 * tests/actions.at (Actions after errors): Use an output format
11453 more similar to that of the Printers and Destructors test.
11454 Test the position of the ';' token too.
11455 (Printers and Destructors): Likewise.
11456 (Printers and Destructors: %glr-parser): Remove for now, to avoid
11457 unnecessarily alarming people when the test fails.
11459 * data/yacc.c (yyerrlab1): Move this label down, so that the
11460 parser does not discard the lookahead token if the user code
11461 invokes YYERROR. This change is required for POSIX conformance.
11463 * lib/error.c: Sync with gnulib.
11465 2002-11-22 Paul Eggert <eggert@twinsun.com>
11467 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
11468 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
11469 * lib/xmalloc.c: Likewise.
11471 2002-11-20 Paul Eggert <eggert@twinsun.com>
11473 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
11475 2002-11-20 Paul Eggert <eggert@twinsun.com>
11477 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
11478 should use `if (! x) abort ();' rather than `assert (x);', and
11479 anyway it's one less thing to worry about configuring.
11481 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
11482 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
11483 and replace all instances of assert with abort.
11484 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
11485 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
11487 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
11488 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
11489 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
11490 hash_find_entry, hash_rehash, hash_insert): Likewise.
11491 * src/conflicts.c (resolve_sr_conflict): Likewise.
11492 * src/lalr.c (set_goto_map, map_goto): Likewise.
11493 * src/nullable.c (nullable_compute): Likewise.
11494 * src/output.c (prepare_rules, token_definitions_output): Likewise.

11497 state_reduction_find): Likewise.
11498 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
11499 symbol_pack): Likewise.
11500 * src/tables.c (conflict_row, pack_vector): Likewise.
11501 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
11502 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
11503 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
11504 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
11506 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
11507 (ARGMATCH_CONSTRAINT): New macro.
11508 (ARGMATCH_ASSERT): Use it.
11510 * src/system.h (verify): New macro.
11511 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
11512 rather than assert.
11513 * src/tables.c (tables_generate): Likewise.
11515 * src/struniq.c (struniq_assert): Now returns void, and aborts
11516 if the assertion is false.
11517 (struniq_assert_p): Remove.
11518 * src/struniq.h: Likewise.
11520 2002-11-18 Paul Eggert <eggert@twinsun.com>
11522 * data/glr.c (yygetLRActions): Replace `yyindex' with
11523 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
11524 This fixes the regression with Sun ONE Studio 7 cc that I reported in
11525 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
11527 2002-11-18 Akim Demaille <akim@epita.fr>
11529 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
11531 From Tim Van Holder.
11533 2002-11-17 Paul Eggert <eggert@twinsun.com>
11535 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
11536 to "SyntaxError" for consistency with my 2002-11-15 change.
11538 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
11539 not define to {}, since this breaks the common use of `YYDPRINTF
11540 ((...));' if a single statement is desired (e.g. before `else').
11541 Work around GCC warnings by surrounding corresponding calls with
11543 (yyhasResolvedValue): Remove unused function.
11544 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
11546 (yyreportSyntaxError): Renamed from yyreportParseError.
11547 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
11549 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
11550 extern when possible. Remove unused initializations.
11552 2002-11-16 Akim Demaille <akim@epita.fr>
11554 Augment the similarity between GLR and LALR traces.
11556 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
11557 (YY_REDUCE_PRINT): New.
11558 (yyparse): Use them.
11559 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
11561 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
11562 state reached after the reduction/recovery, since...
11563 (yyparse, yyprocessOneStack): Report the state we are entering in.
11565 2002-11-16 Akim Demaille <akim@epita.fr>
11567 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
11568 Add support for --trace=skeleton.
11569 * src/scan-skel.l: %option debug.
11570 Scan strings of non-@ or \n instead of character by character.
11571 (scan_skel): Handle trace_skeleton.
11573 (@output_parser_name@, @output_header_name@): ``Restore'' their
11574 support (used to be M4 macros).
11575 * data/yacc.c: Quote larger chunks, a la glr.c.
11576 * data/lalr1.cc: Likewise.
11577 The header guards are no longer available, so use some other
11578 string than `YYLSP_NEEDED'.
11580 2002-11-16 Akim Demaille <akim@epita.fr>
11582 Make the ``Printers and Destructors'' test more verbose, taking
11583 `yacc.c''s behavior as (possibly wrong) reference.
11585 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
11586 instead of fprint on stdout.
11587 Set and report the last_line of the symbols.
11588 Consistently display values and locations.
11590 2002-11-16 Paul Eggert <eggert@twinsun.com>
11592 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
11594 2002-11-15 Paul Eggert <eggert@twinsun.com>
11596 * tests/actions.at (Actions after errors): New test case.
11598 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
11599 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
11600 tests/action.at, tests/calc.at, tests/conflicts.at,
11601 tests/cxx-type.at, tests/regression.at:
11602 "parse error" -> "syntax error" for POSIX compatibility.
11603 "parsing stack overflow..." -> "parser stack overflow" so
11604 that code matches Bison documentation.
11606 2002-11-15 Akim Demaille <akim@epita.fr>
11608 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
11609 take two BRACED_CODE, not two string_content.
11610 Free the scanner's obstack when we are done.
11611 (code_content): New.
11612 * tests/calc.at: Adjust.
11613 * doc/bison.texinfo: Adjust.
11614 Also, make sure to include the `,' for these declarations.
11616 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
11618 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
11619 definition; avoids potential autoreconf problems.
11621 2002-11-15 Akim Demaille <akim@epita.fr>
11623 Always check the value returned by yyparse.
11625 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
11626 returned by yyparse.
11627 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
11629 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
11630 returned by yyparse.
11632 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11634 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
11637 2002-11-14 Paul Eggert <eggert@twinsun.com>
11639 * src/output.c (output_skeleton): Call xfopen instead of
11640 duplicating xfopen's body.
11642 Fix bugs reported by Nelson H. F. Beebe in
11643 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
11645 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
11646 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
11647 Group compiler. Instead, use "$CC -E bar.c". Include the .h
11648 file twice in the grammar, as an extra check.
11650 * tests/input.at (Torturing the Scanner): Surround the
11651 backslash-newline tests with "#if 0", to make it less likely that
11652 we'll run into compiler bugs. Bring back solitary \ inside
11653 comment, but add a closing comment to work around HP C bug. Don't
11654 test backslash-newline in C character constant.
11656 2002-11-14 Akim Demaille <akim@epita.fr>
11658 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
11659 status of the compiler.
11660 Calling `exit 1' is no longer needed.
11661 Reported by Nelson H. F. Beebe.
11663 2002-11-14 Akim Demaille <akim@epita.fr>
11665 * tests/atlocal.in (CPPFLAGS): We have config.h.
11666 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
11668 * tests/actions.at, tests/calc.at, tests/conflicts.at,
11669 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
11670 * tests/regression.at, tests/torture.at: Use them for all the
11671 grammars that are to be compiled.
11672 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
11673 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
11674 * doc/bison.texinfo (GLR Parsers): Document `inline'.
11676 2002-11-14 Akim Demaille <akim@epita.fr>
11678 * doc/bison.texinfo: Various formatting changes (alignments in
11679 samples, additional @group/@end group, GCS in samples.
11680 Use @deffn instead of simple @table to define the directives,
11681 macros, variables etc.
11683 2002-11-13 Paul Eggert <eggert@twinsun.com>
11685 Fix some bugs reported by Albert Chin-A-Young in
11686 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
11688 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
11689 -o c"; the HP C compiler chatters during compilation.
11690 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
11691 * tests/headers.at (export YYLTYPE): Likewise.
11693 * tests/input.at (Torturing the Scanner): Remove lines containing
11694 solitary backslashes, as they tickle a bug in the HP C compiler.
11696 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
11697 comments, since they're not portable. Use GNU coding style.
11699 2002-11-13 Akim Demaille <akim@epita.fr>
11701 * data/yacc.c: Leave bigger chunks of quoted text.
11702 (YYDSYMPRINTF): New.
11703 Use it to report symbol activities.
11704 * data/glr.c (YYDSYMPRINTF): New.
11707 2002-11-12 Paul Eggert <eggert@twinsun.com>
11711 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
11712 (yyglrReduce): Return yyok, not 0.
11713 This should avoid the enumerated-type warnings reported
11714 by Nelson H. F. Beebe in
11715 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
11717 * lib/bbitset.h (BITSET_INLINE): Remove.
11718 * lib/bitset.h [! BITSET_INLINE]: Remove.
11719 (bitset_set, bitset_reset, bitset_test): Rename local vars
11720 to avoid shadowing warnings by GCC.
11722 * data/glr.c (inline): Remove #define. It's the user's
11723 responsibility to #define it away, just like 'const'.
11724 This fixes one of the bugs reported by Nelson H. F. Beebe in
11725 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
11727 * Makefile.maint (po-check): Scan .l and .y files instead of the
11728 .c and the .h files that they generate. This fixes the bug
11729 reported by Tim Van Holder in:
11730 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
11731 Look for N_ as well as for _. Try to avoid matching #define for
11733 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
11734 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
11735 * src/scan-gram.l: Revamp regular expressions so that " and '
11736 do not confuse xgettext.
11738 * src/struniq.h (struniq_new): Do not declare the return type
11739 to be 'const'; this violates the C standard.
11740 * src/struniq.c (struniq_new): Likewise.
11742 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
11744 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
11745 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
11748 2002-11-12 Akim Demaille <akim@epita.fr>
11750 * Makefile.maint: Sync with Autoconf:
11751 (local_updates): New.
11753 2002-11-12 Akim Demaille <akim@epita.fr>

11757 2002-11-12 Akim Demaille <akim@epita.fr>
11759 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
11762 2002-11-12 Akim Demaille <akim@epita.fr>
11764 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
11767 2002-11-12 Akim Demaille <akim@epita.fr>
11769 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
11770 Use it to test the GLR parser.
11772 2002-11-12 Akim Demaille <akim@epita.fr>
11774 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
11776 * data/glr.c (yystos): New.
11777 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
11778 (YYDSYMPRINT): New.
11779 (yyval): Don't define it, it is handled via M4.
11780 (yyrecoverParseError): Free verbosely the discarded symbols.
11781 * data/yacc.c (yysymprint): Remove, rather...
11782 (b4_yysymprint_generate): invoke.
11783 * data/c.m4 (b4_yysymprint_generate): New.
11784 Accept pointers as arguments, as opposed to the version from
11786 (b4_yydestruct_generate): Likewise.
11787 * tests/cations.at (Printers and Destructors): Use Bison directives
11788 instead of CPP macros.
11789 Don't rely on internal details.
11791 2002-11-12 Akim Demaille <akim@epita.fr>
11793 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
11794 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
11795 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
11796 it against YYEMPTY and so forth), work on yytoken (i.e., set
11797 it to YYEMPTY etc.).
11798 (yydestruct): Replace with a b4_yydestruct_generate invocation.
11799 (b4_symbol_actions): Remove.
11800 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
11801 for 0, end-of-input.
11803 2002-11-12 Akim Demaille <akim@epita.fr>
11805 * doc/bison.texinfo (Destructor Decl): New.
11807 2002-11-12 Akim Demaille <akim@epita.fr>
11809 * src/tables.c (tables_generate): Use free for pointers that
11810 cannot be NULL, not XFREE.
11811 (pack_vector): Use assert, not fatal, for bound violations.
11812 * src/state.c (state_new): Likewise.
11813 * src/reader.c (reader): Likewise.
11814 * src/lalr.c (set_goto_map): Likewise.
11815 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
11818 2002-11-12 Akim Demaille <akim@epita.fr>
11820 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
11822 * src/scan-gram.l (last_string): Is global to the file, not to
11824 * src/parse-gram.y (input): Don't append the epilogue here,
11825 (epilogue.opt): do it here, and free the scanner's obstack.
11826 * src/reader.c (epilogue_set): Rename as...
11827 (epilogue_augment): this.
11828 * data/c.m4 (b4_epilogue): Defaults to empty.
11830 2002-11-12 Akim Demaille <akim@epita.fr>
11832 * src/getargs.c (long_options): Remove duplicates.
11833 * src/vmsgetargs.c, src/build.com, src/bison.cld, src/vmshlp.mar:
11835 * doc/bison.rnh: Remove.
11836 * doc/bison.texinfo (VMS Invocation): Remove.

11886 2002-11-11 Paul Eggert <eggert@twinsun.com>
11888 Revamp to fix many (but not all) of the C- and M4-related quoting
11889 problems. Among other things, this fixes the Bison bug reported
11890 by Jan Hubicka when processing the Bash grammar; see:
11891 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
11893 Use new @ escapes consistently. Represent brackets with @{ and @}
11894 rather than @<:@ and @:>@, since this works a bit better with dumb
11895 editors like vi. Represent @ with @@, since @ is now consistently
11896 an escape. Use @oline@ and @ofile@ rather than __oline__ and
11897 __ofile__, to avoid unexpected expansions. Similarly, use @output
11898 rather than #output.
11900 * data/c.m4 (b4_copyright): Omit file name from comment, since
11901 the file name could contain "*/".
11902 (b4_synclines_flag): Don't quote the 2nd argument; it should already
11903 be quoted. All uses changed.
11905 * data/glr.c: Use new @ escapes consistently.
11906 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
11907 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
11908 Remove, since they couldn't handle arbitrary characters in file
11910 * data/lalr1.cc: Likewise.
11911 * data/yacc.c: Likewise.
11913 * src/files.c (output_infix): Remove; all uses removed.
11914 * src/files.h: Likewise.
11916 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
11917 mishandled funny characters in file names, and anyway it isn't
11919 * data/yacc.c: Likewise.
11920 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
11922 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
11923 * data/yacc.c: Likewise.
11925 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
11927 (muscle_init): Quote filename as a C string.
11928 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
11929 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
11930 * src/output.c (escaped_file_name_output): New function.
11931 (prepare_symbols): Quote tokens for M4.
11932 (prepare): Don't insert output_infix, output_prefix,
11933 output_parser_name, output_header_name; this is now down by scan-skel.
11934 Insert skeleton as a C string.
11936 * src/output.c (user_actions_output, symbol_destructors_output,
11937 symbol_printers_output): Quote filenames for C and M4.
11938 * src/reader.c (prologue_augment, epilogue_set): Likewise.
11940 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
11941 escapes other than \\ and \'; this simplifies the code.
11942 (<SC_STRING>): Likewise, for \\ and \".
11943 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
11944 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
11945 Use new escapes @{ and @} for [ and ].
11947 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
11948 them with auto vars.
11949 Switch to new escape scheme, where @ is the escape character uniformly.
11950 Abort if a stray escape character is found. Avoid unbounded input
11951 buffer when parsing non-escaped text.
11953 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
11954 __oline__, #output, $@, and @{ do not have unintended meanings.
11956 2002-11-09 Paul Eggert <eggert@twinsun.com>
11958 Fix the test failure due to GCC warnings described in
11959 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
11960 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
11961 evaluate to 0 if it's impossible for NINF to be in the respective
11963 (yygetLRActions, yyrecoverParseError): Use them.
11965 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
11966 counted in the token inserted at end of file. Now takes
11967 location_t *, not location_t, so that the location can be
11968 adjusted. All uses changed.
11970 * tests/regression.at (Invalid inputs): Adjust wording in
11971 diagnostic to match the new behavior.
11973 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
11974 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
11975 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
11976 abort ();'. This reduces the runtime of the "Many lookaheads"
11977 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
11980 2002-11-07 Paul Eggert <eggert@twinsun.com>
11982 * src/parse-gram.y (CHARACTER): Remove unused token.
11985 * src/scan-gram.l: Remove stack option. We no longer use the
11986 stack, since the stack was never deeper than 1; instead, use the
11987 new auto var c_context to record the stacked value.
11989 Remove nounput option. At an unexpected end of file, we now unput
11990 the minimal input necessary to end cleanly; this simplifies the
11993 Avoid unbounded token sizes where this is easy.
11995 (unexpected_end_of_file): New function.
11996 Use it to systematize the error message on unexpected EOF.
11997 (last-string): Now auto, not static.
11998 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
11999 (scanner_last_string_free): Remove; not used.
12000 (percent_percent_count): Move decl to just before use.
12001 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
12002 not the (never otherwised-used) CHARACTER.
12004 2002-11-07 Akim Demaille <akim@epita.fr>
12006 Let yyerror always receive the msg as last argument, so that
12007 yyerror can be variadic.
12009 * data/yacc.c (b4_yyerror_args): New.
12010 Use it when calling yyerror.
12011 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

12024 * src/output.c (symbol_printers_output)
12025 (symbol_destructors_output): Quote the file name.

12056 * src/tables.c (matching_state): Don't allow states to match if
12057 either has GLR conflict entries.
12059 2002-11-05 Paul Eggert <eggert@twinsun.com>
12061 * src/scan-gram.l: Use more accurate diagnostics, e.g.
12062 "integer out of range" rather than "invalid value".
12063 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
12066 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
12067 Also, remove one static variable in the scanner.
12069 * src/scan-gram.l (braces_level): Now auto, not static.
12070 Initialize to zero if the compiler is being picky.
12071 (INITIAL): Clear braces_level instead of incrementing it.
12072 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,

12074 * src/system.h (IF_LINT): New macro, taken from coreutils.
12075 * configure.ac: Define "lint" if --enable-gcc-warnings.

12082 2002-11-04 Akim Demaille <akim@epita.fr>
12084 * Makefile.maint: Update from Autoconf.
12085 (update, cvs-update, po-update, do-po-update): New.

12108 * src/reader.c (get_merge_function, grammar_current_rule_check):
12109 Use consistent diagnostics for reporting type name clashes.
12110 Quote the types with <>, for consistency with Yacc.
12111 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
12113 2002-11-03 Akim Demaille <akim@epita.fr>
12115 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):

12136 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
12137 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
12138 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.

12196 with quote slot used by complain_at.
12198 * tests/input.at: Add tests for backslash-newline, m4 quotes
12199 in symbols, long literals, and funny escapes in strings.

12215 2002-11-02 Paul Eggert <eggert@twinsun.com>
12217 * src/reader.c: Don't include quote.h; not needed.

12222 bug in trigraph handling.
12224 * src/output.c (prepare_symbols): When printing token names,
12225 escape "[" as "@<:@" and likewise for "]".
12227 * src/system.h (errno): Remove declaration, as we are now
12228 assuming C89 or better, and C89 guarantees errno.
12230 2002-10-30 Paul Eggert <eggert@twinsun.com>
12232 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
12233 Check for close failures.
12234 * src/files.h (xfclose): Return void, not int, since it always
12236 * src/files.c (xfclose): Likewise. Report I/O error if ferror
12238 * src/output.c (output_skeleton): Use xfclose rather than fclose
12239 and ferror. xfclose now checks ferror.
12241 * data/glr.c (YYLEFTMOST_STATE): Remove.
12242 (yyreportTree): Use a stack-based leftmost state. This avoids
12243 our continuing battles with bogus warnings about initializers.
12245 2002-10-30 Akim Demaille <akim@epita.fr>
12247 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

12260 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
12261 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
12262 we use malloc. Don't assume 'A' through 'Z' are contiguous.
12263 Don't assume strdup exists; POSIX says its an XSI extension.
12264 Check for buffer overflow on input.
12266 2002-10-24 Akim Demaille <akim@epita.fr>
12268 * src/output.c (output_skeleton): Don't disable M4sugar comments
12269 too soon: it results in comments being expanded.

12273 2002-10-24 Akim Demaille <akim@epita.fr>
12275 * data/yacc.c (m4_int_type): New.
12276 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
12277 char' as only yacc.c wants K&R portability.
12278 * data/glr.c (yysigned_char): Remove.
12279 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
12280 Reported by Quoc Peyrot.
12282 2002-10-23 Paul Eggert <eggert@twinsun.com>
12284 * src/main.c (main): With --trace=time, report times even if a
12285 non-fatal error occurs. Formerly, the times were reported in some
12286 such cases but not in others.
12287 * src/reader.c (reader): Just return if a complaint has been issued,
12288 instead of exiting, so that 'main' can report times.
12290 2002-10-22 Akim Demaille <akim@epita.fr>
12292 * src/system.h: Include sys/types.
12293 Reported by Bert Deknuydt.
12295 2002-10-23 Paul Eggert <eggert@twinsun.com>
12297 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
12298 Suggested by Art Haas.
12300 2002-10-22 Paul Eggert <eggert@twinsun.com>
12302 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
12303 decl; not needed any more.
12304 * src/main.c (main): Use return to exit, undoing yesterday's change.
12305 The last OS that we could find where this wouldn't work is
12306 SunOS 3.5, and that's too old to worry about now.
12308 * data/glr.c (struct yyltype): Define members even when not
12309 doing locations. This is more consistent with yacc.c, and it
12310 works around the following bug reports:
12311 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
12312 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
12314 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
12315 @acronym consistently. Standardize on "Yacc" instead of "YACC",
12316 "Algol" instead of "ALGOL". Give a bit more history about BNF.
12318 2002-10-22 Akim Demaille <akim@epita.fr>
12320 * data/README: New.
12322 2002-10-21 Paul Eggert <eggert@twinsun.com>
12324 Be consistent about 'bool'; the old code used an enum in one
12325 module and an int in another, and this violates the C standard.
12326 * m4/stdbool.m4: New file, from coreutils 4.5.3.
12327 * configure.ac (AC_HEADER_STDBOOL): Add.
12328 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
12329 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
12330 * src/symtab.c (hash_compare_symbol_t): Likewise.
12331 * src/system.h (bool, false, true): Use a definition consistent
12332 with ../lib/hash.c. All uses changed.
12334 * src/complain.c (warning_issued): Renamed from warn_message_count,
12335 so that we needn't worry about integer overflow (!).
12336 Now of type bool. All uses changed.
12337 (complaint_issued): Renamed from complain_message_count; likewise.
12339 * src/main.c (main): Use exit to exit with failure.
12341 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
12342 rather than 1 and 0.
12343 * src/main.c (main): Likewise.
12344 * src/getargs.c (getargs): Likewise.
12345 * src/reader.c (reader): Likewise.
12347 * src/getarg.c (getargs): Remove duplicate code for
12348 "Try `bison --help'".
12350 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
12351 What was that "2" for?
12353 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
12354 * src/getargs.c (usage): Likewise.
12356 * src/getargs.c (getargs): When there are too few operands, report
12357 the last one. When there are too many, report the first extra
12358 one. This is how diffutils does it.
12360 2002-10-20 Paul Eggert <eggert@twinsun.com>
12362 Remove K&R vestiges.
12363 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
12364 * src/complain.c (VA_START): Remove. Assume prototypes.
12365 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
12366 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
12367 fatal): Assume prototypes.
12368 * src/complain.h: Assume prototypes.
12369 * src/system.h (PARAMS): Remove.
12370 Include <limits.h> unconditionally, since it's guaranteeed even
12371 for a freestanding C89 compiler.
12372 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
12373 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
12375 2002-10-20 Akim Demaille <akim@epita.fr>
12377 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.

12380 (yyresolveStates, yyresolveAction, yyresolveStack)
12381 (yyprocessOneStack): Use them.
12382 (yy_reduce_print): New.
12383 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
12385 2002-10-20 Akim Demaille <akim@epita.fr>
12387 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
12388 arguments and output `void'.
12389 (b4_c_function): Rename as...
12390 (b4_c_function_def): this.
12391 (b4_c_function_decl, b4_c_ansi_function_def)
12392 (b4_c_ansi_function_decl): New.
12393 Change the interpretation of the arguments: before `int, foo', now
12395 * data/yacc.c (yyparse): Prototype and define thanks to these.
12396 Adjust b4_c_function_def uses.
12397 * data/glr.c (yyparse): Likewise, but ANSI only.
12399 2002-10-20 Akim Demaille <akim@epita.fr>
12401 * src/output.c (prepare): Move the definition of `tokens_number',
12402 `nterms_number', `undef_token_number', `user_token_number_max'
12404 (prepare_tokens): Here.
12405 (prepare_tokens): Rename as...
12406 (prepare_symbols): this.
12407 (prepare): Move the definition of `rules_number' to...
12408 (prepare_rules): here.
12409 (prepare): Move the definition of `last', `final_state_number',
12410 `states_number' to...
12411 (prepare_states): here.
12412 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
12414 2002-10-20 Akim Demaille <akim@epita.fr>
12416 * src/tables.h, src/tables.c, src/output.c: Comment changes.
12418 2002-10-20 Akim Demaille <akim@epita.fr>
12420 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
12423 2002-10-20 Akim Demaille <akim@epita.fr>
12425 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
12426 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
12428 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
12430 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
12431 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
12434 2002-10-19 Paul Eggert <eggert@twinsun.com>
12436 Do not create a temporary file, as that involves security and
12437 cleanup headaches. Instead, use a pair of pipes.
12438 Derived from a suggestion by Florian Krohm.
12439 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
12440 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
12441 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
12442 (BISON_PREREQ_SUBPIPE): Add.
12443 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
12444 Add subpipe.h, subpipe.c.
12445 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
12446 * po/POTFILES.in: Add lib/subpipe.c.

12448 (m4_invoke): Remove decl.
12449 (scan_skel): New decl.
12450 (output_skeleton): Use pipe rather than temporary file for m4 input.
12451 Check that m4sugar.m4 is readable, to avoid deadlock.
12452 Check for pipe I/O error.
12453 * src/scan-skel.l (readpipe): Remove decl.
12454 (scan_skel): New function, to be used in place of m4_invoke.
12455 Read from stream rather than file.
12457 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
12458 float, as this generates a warning on Solaris 8 + GCC 3.2 with
12459 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
12460 this generates a more-accurate value anyway.
12462 * lib/timevar.c (timervar_accumulate): Rename locals to
12463 avoid confusion with similarly-named more-global.
12464 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
12466 * src/output.c (prepare): Use xstrdup to convert char const *
12467 to char *, to avoid GCC warning.
12469 2002-10-19 Akim Demaille <akim@epita.fr>
12471 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
12472 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
12473 Use them to have `calc.y' ready for %pure-parser.
12474 * data/yacc.c (YYLEX): Pass a yylex return type to
12475 b4_c_function_call.
12477 2002-10-19 Akim Demaille <akim@epita.fr>
12479 Prototype support of %lex-param and %parse-param.
12481 * src/parse-gram.y: Add the definition of the %lex-param and
12482 %parse-param tokens, plus their rules.
12483 Drop the `_' version of %glr-parser.
12485 * src/scan-gram.l (INITIAL): Scan them.
12486 * src/muscle_tab.c: Comment changes.
12487 (muscle_insert, muscle_find): Rename `pair' as `probe'.
12488 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
12489 (muscle_entry_s): The `value' member is no longer const.
12490 Adjust all dependencies.
12491 * src/muscle_tab.c (muscle_init): Adjust: use
12492 MUSCLE_INSERT_STRING.
12493 Initialize the obstack earlier.
12494 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
12495 (muscle_pair_list_grow): New.
12496 * data/c.m4 (b4_c_function_call, b4_c_args): New.
12497 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
12498 * tests/calc.at: Use %locations, not --locations.
12499 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
12501 2002-10-19 Akim Demaille <akim@epita.fr>
12503 * src/getargs.c (usage): Take status as argument and exit
12505 Report the traditional `Try ... --help' message when status != 0.
12506 (usage, version): Don't take a FILE * as arg, it is pointless.
12507 (getargs): When there is an incorrect number of arguments, make it
12508 an error, and report it GNUlically thanks to `usage ()'.
12510 2002-10-18 Paul Eggert <eggert@twinsun.com>
12512 * data/glr.c (yyreportParseError): Don't assume that sprintf
12513 yields the length of the printed string, as this is not true
12514 on SunOS 4.1.4. Reported by Peter Klein.
12516 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
12517 * tests/conflicts.at (%nonassoc and eof): Likewise.
12518 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
12520 2002-10-17 Akim Demaille <akim@epita.fr>
12522 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
12523 * src/getargs.c (trace_types, trace_args): Adjust.
12524 * src/reader.c (grammar_current_rule_prec_set)
12525 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
12526 Standardize error messages.
12527 And s/@prec/%prec/!
12528 (reader): Use trace_flag to enable scanner/parser debugging,
12529 instead of an adhoc scheme.
12530 * src/scan-gram.l: Remove trailing debugging code.
12532 2002-10-16 Paul Eggert <eggert@twinsun.com>
12534 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
12537 * NEWS: Officially drop support for building Bison with K&R C,
12538 since it didn't work anyway and it's not worth worrying about.
12539 * Makefile.maint (wget_files): Remove ansi2knr.c.
12540 (ansi2knr.c-url_prefix): Remove.
12541 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
12542 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
12543 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
12545 2002-10-15 Paul Eggert <eggert@twinsun.com>
12547 Stop using the "enum_" trick for K&R-style function definitions;
12548 it confused me, and I was the author! Instead, assume that people
12549 who want to use K&R C compilers (when using these modules in GCC,
12550 perhaps?) will run ansi2knr.
12552 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
12553 All uses of "enum_" changed to "enum ".
12554 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
12555 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
12557 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

12565 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
12566 Use function prototypes; this removes the need for declaring
12567 static functions simply to provide their prototypes.
12568 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

12629 2002-10-14 Akim Demaille <akim@epita.fr>
12631 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
12634 2002-10-14 Akim Demaille <akim@epita.fr>
12636 * src/tables.c (table_ninf_remap): base -> tab.
12637 Reported by Matt Rosing.
12639 2002-10-14 Paul Eggert <eggert@twinsun.com>
12641 * tests/action.at, tests/calc.at, tests/conflicts.at,
12642 tests/cxx-type.at, tests/headers.at, tests/input.at,
12643 tests/regression.at, tests/synclines.at, tests/torture.at:
12644 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
12645 so that the tests still work even if POSIXLY_CORRECT is set.
12646 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
12648 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
12649 for portability to K&R hosts. Fix typo: signed char is guaranteed
12650 only to 127, not to 128.
12651 * data/glr.c (yysigned_char): New type.
12652 * data/yacc.c (yysigned_char): Likewise.
12653 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
12655 2002-10-13 Paul Eggert <eggert@twinsun.com>
12657 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
12658 true due to limited range of data type" warning from GCC.
12660 * data/c.m4 (b4_token_defines): Protect against double-inclusion
12661 by wrapping enum yytokentype's definition inside #ifndef
12662 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
12664 2002-10-13 Akim Demaille <akim@epita.fr>
12666 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
12667 Un yy- yyrhs to avoid the name clash with the global YYRHS.
12669 2002-10-13 Akim Demaille <akim@epita.fr>
12671 * Makefile.maint: Update from Autoconf 2.54.
12672 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
12674 2002-10-13 Akim Demaille <akim@epita.fr>
12676 * src/print.c (print_state): Separate the list of solved conflicts
12677 from the other items.
12678 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
12680 2002-10-13 Akim Demaille <akim@epita.fr>
12682 Let nondeterministic skeletons be usable with deterministic
12685 With the patch, GAWK compiled by GCC without -O2 passes its test
12686 suite using a GLR parser driven by LALR tables. It fails with -O2
12687 because `struct stat' gives two different answers on my machine:
12688 88 (definition of an auto var) and later 96 (memset on this var).
12689 Hence the stack is badly corrumpted. The headers inclusion is to
12690 blame: if I move the awk.h inclusion before GLR's system header
12691 inclusion, the two struct stat have the same size.
12693 * src/tables.c (pack_table): Always create conflict_table.
12694 (token_actions): Always create conflict_list.
12695 * data/glr.c (YYFLAG): Remove, unused.
12697 2002-10-13 Akim Demaille <akim@epita.fr>
12699 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
12701 (VALGRIND, GXX): New.
12702 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
12703 * tests/bison.in: Run $PREBISON a pre-command.
12704 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
12705 (maintainer-check-g++): New.
12706 * Makefile.am (maintainer-check): New.
12708 2002-10-13 Akim Demaille <akim@epita.fr>
12710 * data/glr.c: Formatting changes.
12711 Tweak some trace messages to match yacc.c's.

12715 GLR parsers sometimes raise parse errors instead of performing the
12717 Reported by Charles-Henry de Boysson.
12719 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
12720 check the length of the traces when %glr.
12721 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
12723 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
12725 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
12726 (yyltype): Remove the yy prefix from the member names.
12727 (yytable): Complete its comment.
12728 (yygetLRActions): Map error action number from YYTABLE from
12730 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
12731 (which was a bug: it should have been YYTABEL_NINF, and yet it was
12732 not satisfying as we could compare an YYACTION computed from
12733 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
12734 only value for error actions.
12735 (yyreportParseError): In verbose parse error messages, don't issue
12736 `error' in the list of expected tokens.
12737 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
12738 next action to perform to match glr.c's decoding.
12739 (yytable): Complete its comment.

12743 Fix problem reported by Henrik Grubbstroem in
12744 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
12745 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
12746 because the Bison parser reads the second action before reducing
12748 * src/scan-gram.l (rule_length): New static var.
12749 Use it to keep track of the rule length in the scanner, since
12750 we can't expect the parser to be in lock-step sync with the scanner.
12751 (handle_action_dollar, handle_action_at): Use this var.
12752 * tests/actions.at (Exotic Dollars): Test for the problem.
12754 2002-10-12 Paul Eggert <eggert@twinsun.com>
12756 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
12757 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
12758 Include <sys/time.h> when checking for clock_t and struct tms.
12759 Use same include order as source.
12760 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
12761 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
12763 * lib/timevar.c: Update copyright date and clarify comments.
12764 (get_time) [IN_GCC]: Keep the GCC version for reference.
12766 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
12767 GCC version as of today, then merge Bison's changes.
12768 Change "GCC" to "Bison" in copyright notice. timevar.def's
12769 author is Akim, so change that too.
12771 * src/reader.c (grammar_current_rule_check):
12772 Don't worry about the default action if $$ is untyped.
12773 Prevents bogus warnings reported by Jim Gifford in
12774 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
12776 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
12777 * data/glr.c, data/lalr1.cc, data/yacc.c:
12778 Output token definitions before the first part of user declarations.
12779 Fixes compatibility problem reported by Jim Gifford for kbd in
12780 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
12782 2002-10-11 Paul Eggert <eggert@twinsun.com>
12784 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
12785 (yyparse): here. This undoes some of the 2002-07-25 change.
12786 Compatibility problem reported by Ralf S. Engelschall with
12787 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
12789 2002-10-11 Akim Demaille <akim@epita.fr>
12791 * tests/regression.at Characters Escapes): New.
12792 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
12794 Reported by Jan Nieuwenhuizen.

12800 2002-10-10 Paul Eggert <eggert@twinsun.com>
12802 Portability fixes for bitsets; this also avoids several GCC
12805 * lib/abitset.c: Include <stddef.h>, for offsetof.
12806 * lib/lbitset.c: Likewise.
12808 * lib/abitset.c (abitset_bytes): Return a size that is aligned
12809 properly for vectors of objects. Do not assume that adding a
12810 header size to a multiple of a word size yields a value that is
12811 properly aligned for the whole union.
12812 * lib/bitsetv.c (bitsetv_alloc): Likewise.
12814 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
12815 unique names for structures.
12816 * lib/ebitset.c (ebitset_bytes): Likewise.
12817 * lib/lbitset.c (lbitset_bytes): Likewise.
12819 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,

12824 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
12825 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
12826 to improve the type-checking that GCC can do.
12827 * lib/bitset.c (bitset_op4_cmp): Likewise.
12828 * lib/bitset_stats.c (bitset_stats_count,
12829 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

12836 bitset_stats_andn_or_cmp, bitset_stats_or_and,
12837 bitset_stats_or_and_cmp): Likewise.
12838 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
12839 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,

12841 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
12843 * lib/abitset.h: Include bitset.h, not bbitset.h.
12844 * lib/ebitset.h: Likewise.
12845 * lib/lbitset.h: Likewise.
12847 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
12848 All instances of parameters of type enum bitset_opts are now of
12849 type enum_bitset_opts, to conform to the C Standard, and similarly
12850 for enum_bitset_type.
12851 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
12852 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
12854 Do not use "struct bitset_struct" to mean different things in
12855 different modules. Not only is this confusing, it violates
12856 the C Standard, which requires that structure types in different
12857 modules must be compatible if one is to be passed to the other.
12858 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
12859 All instances of "struct bitset_struct *" replaced with "bitset".
12860 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
12861 (union bitset_union, struct abitset_struct, struct ebitset_struct,
12862 struct lbitset_struct, struct bitset_stats_struct): New types.
12863 All uses of struct bitset_struct changed to union bitset_union,
12865 * lib/abitset.c (struct abitset_struct, abitset,
12866 struct bitset_struct): Remove.
12867 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
12868 struct bitset_struct): Remove.
12869 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
12870 bitset_struct): Remove.
12871 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
12874 Do not call a function of type T using a call that assumes the
12875 function is of a different type U. Standard C requires that a
12876 function must be called with a type that is compatible with its
12878 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
12880 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
12882 * lib/ebitset.c (PFV): Remove.
12883 * lib/lbitset.c (PFV): Likewise.
12884 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
12885 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
12887 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
12888 (ebitset_vtable): Use them.
12889 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
12890 lbitset_xor): New functions.
12891 (lbitset_vtable): Use them.
12893 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
12896 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
12898 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
12899 Use offsetof, for simplicity.
12901 2002-10-06 Paul Eggert <eggert@twinsun.com>
12903 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
12904 the same width as int. This reapplies a hunk of the 2002-08-12 patch
12905 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
12906 which was inadvertently undone by the 2002-09-30 patch.
12907 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
12908 the same width as int.
12910 2002-10-04 Paul Eggert <eggert@twinsun.com>
12914 * configure.ac (AC_INIT), NEWS: Increment version number.
12916 * doc/bison.texinfo: Minor spelling, grammar, and white space
12918 (Symbols): Mention that any negative value returned from yylex
12919 signifies end-of-input. Warn about negative chars. Mention
12920 the portable Standard C character set.
12922 The GNU coding standard says CFLAGS and YFLAGS are reserved
12923 for the installer to set.
12924 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
12925 * src/Makefile.am (AM_CFLAGS): Likewise.
12926 (AM_YFLAGS): Renamed from YFLAGS.
12928 Fix some MAX and MIN problems.
12929 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
12930 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
12931 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
12932 * src/reader.c (reader): Use it.
12934 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
12935 POSIX 1003.1-2001 has removed fgrep.
12937 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
12939 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
12940 interpreted as signed.

13013 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

13168 as int, and similarly for yyposn and YYINDEX.

13216 (bitset_test): Now returns int, not unsigned long.

13265 as it mishandles negative chars and it may not work as expected
13266 outside the C locale.
13268 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
13269 this is a GCC extension and is not portable to other compilers.

13279 * tests/regression.at: Do not use 'cc -c input.c -o input';
13280 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
13282 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
13283 exit status as failure, not just exit status 1. Sun C exits
13284 with status 2 sometimes.

13451 different: save its reduction (accept) instead of having a state

13453 Note: the final state is now a ``regular'' state, i.e., the
13454 parsers now contain `reduce 0' as default reduction.

13502 yycontrol without making too strong assumptions on the parser
13504 * src/output.c (prepare_tokens): Use the real 0th value of
13505 token_translations instead of `0'.
13506 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
13508 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
13509 for the time being: %locations ought to provide it to yyerror.
13511 2002-07-25 Akim Demaille <akim@epita.fr>
13513 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

13525 Use rule_number_as_item_number and item_number_as_rule_number.
13526 Adjust to `derive' now containing possibly 0.
13527 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
13528 Handle the `- 1' part in rule numbers from/to item numbers.

14674 Remove `%thong' support as it is undocumented, unused, duplicates

15169 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
15170 etc. instead of 10, 20, 30 (which was used to `jump' over error

15210 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
15211 full stderr, and strip it according to the bison options, instead

15214 Adjust all the invocations.
15215 Add an invocation exercising the error token.
15216 Add an invocation demonstrating a stupid error message.
15217 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

15236 `user_token_number_max'.

15482 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
15483 lacking `+ 1' to nrules, Bison reported as useless a token if it
15484 was used solely to set the precedence of the last rule...
15486 2002-04-07 Akim Demaille <akim@epita.fr>
15488 * data/bison.c++, data/bison.simple: Don't output the current file
15489 name in #line, to avoid useless diffs between two identical
15490 outputs under different names.

15494 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

15510 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
15511 RHS, instead of being an index in RITEMS.
15513 2002-04-04 Paul Eggert <eggert@twinsun.com>
15515 * doc/bison.texinfo: Update copyright date.
15516 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

16055 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
16056 'switch' without a following semicolon.
16057 * tests/regression.at (braces parsing): New.
16059 2002-01-06 Akim Demaille <akim@epita.fr>
16061 Bison is dead wrong in its RR conflict reports.
16063 * tests/torture.at (GNU Cim Grammar): New.
16064 * src/conflicts.c (count_rr_conflicts): Fix.
16066 2002-01-06 Akim Demaille <akim@epita.fr>
16068 Creating package.m4 from configure.ac causes too many problems.
16070 * tests/Makefile.am (package.m4): Create it by hand,
16071 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
16073 2002-01-06 Akim Demaille <akim@epita.fr>
16075 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
16078 2002-01-04 Paul Eggert <eggert@twinsun.com>
16080 * doc/bison.texinfo (Debugging):
16081 Remove YYSTDERR; it's no longer defined or used.
16082 Also, s/cstdio.h/cstdio/.
16084 2002-01-03 Akim Demaille <akim@epita.fr>
16086 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
16088 2002-01-03 Akim Demaille <akim@epita.fr>
16090 * src/parse-skel.y (process_skeleton): Don't bind the parser's
16091 tracing code to --trace, wait for a better --trace option, with
16094 2002-01-03 Akim Demaille <akim@epita.fr>
16096 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
16097 The ISO C++ standard is extremely clear about it: stderr is
16098 considered a macro, not a regular symbol (see table 94 `Header
16099 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
16100 Therefore std:: does not apply to it. It still does with fprintf.
16101 Also, s/cstdio.h/cstdio/.
16103 2002-01-03 Akim Demaille <akim@epita.fr>
16105 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
16106 for non system headers.
16108 2002-01-02 Akim Demaille <akim@epita.fr>
16110 Equip the skeleton chain with location tracking, runtime trace,
16111 pure parser and scanner.
16113 * src/parse-skel.y: Request a pure parser, locations, and prefix
16115 (%union): Having several members with the same type does not help
16116 type mismatches, simplify.
16117 (YYPRINT, yyprint): New.
16118 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
16119 (skel_error): this.
16121 * src/scan-skel.l: Adjust to these changes.
16122 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
16123 (LOCATION_PRINT, skel_control_t): New.
16125 2001-12-30 Akim Demaille <akim@epita.fr>
16127 * src/parse-skel.y: Get rid of the shift/reduce conflict:
16128 replace `gb' with BLANKS.
16129 * src/scan-skel.l: Adjust.
16131 2001-12-30 Akim Demaille <akim@epita.fr>
16133 * src/system.h: We don't need nor want bcopy.
16134 Throw away MS-DOS crap: we don't need getpid.
16135 * configure.in: We don't need strndup. It was even causing
16136 problems: because Flex includes the headers *before* us,
16137 _GNU_SOURCE is not defined by config.h, and therefore strndup was
16139 * lib/xstrndup.c: New.
16140 * src/scan-skel.l: Use it.
16141 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
16142 * src/parse-skel.y: Use %directives instead of #defines.
16144 2001-12-30 Akim Demaille <akim@epita.fr>
16146 * src/skeleton.h: New.
16147 * src/output.c (output_parser, output_master_parser): Remove, dead
16149 * src/output.h (get_lines_number, actions_output, guards_output)
16150 (token_definitions_output): Prototype them.
16151 * src/parse-skel.y: Add the license notice.
16152 Include output.h and skeleton.h.
16153 (process_skeleton): Returns void, and takes a single parameter.
16154 * src/scan-skel.l: Add the license notice.
16155 Include skeleton.h.
16156 Don't use %option yylineno: it seems that then Flex imagines
16157 REJECT has been used, and therefore it won't reallocate its
16158 buffers (which makes no other sense to me than a bug). It results
16159 in warnings for `unused: yy_flex_realloc'.
16161 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
16163 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16164 (MUSCLE_INSERT_PREFIX): ...to there.
16165 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16166 (MUSCLE_INSERT_PREFIX): Move from here...
16168 * src/bison.hairy: Add a section directive. Put braces around muscle
16169 names. This parser skeleton is still broken, but Bison should not
16170 choke on a bad muscle 'syntax'.
16171 * src/bison.simple: Add a section directive. Put braces around muscle
16174 * src/files.h (strsuffix, stringappend): Add declarations.
16175 (tab_extension): Add declaration.
16176 (short_base_name): Add declaration.
16178 * src/files.c (strsuffix, stringappend): No longer static. These
16179 functions are used in the skeleton parser.
16180 (tab_extension): New.
16181 (compute_base_names): Use the computations done in this function
16182 to guess if the generated parsers should have '.tab' in their
16184 (short_base_name): No longer static.
16186 * src/output.c (output_skeleton): New.
16187 (output): Disable call to output_master_parser, and give a try to
16188 a new skeleton handling system.
16189 (guards_output, actions_output): No longer static.
16190 (token_definitions_output, get_lines_number): No longer static.
16192 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
16194 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
16197 * src/parse-skel.y: New file.
16198 * src/scan-skel.l: New file.
16200 2001-12-29 Akim Demaille <akim@epita.fr>
16202 %name-prefix is broken.
16204 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
16205 Adjust all dependencies.
16206 * tests/headers.at (export YYLTYPE): Strengthen this test: use
16209 Renaming yylval but not yylloc is not consistent. Now we do.
16211 * src/bison.simple: Prefix yylloc if used.
16212 * doc/bison.texinfo (Decl Summary): Document that.
16214 2001-12-29 Akim Demaille <akim@epita.fr>
16216 * doc/bison.texinfo: Promote `%long-directive' over
16218 Remove all references to fixed-output-files, yacc is enough.
16220 2001-12-29 Akim Demaille <akim@epita.fr>
16222 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
16223 user prologue. These are defaults.
16224 * tests/actions.at (Mid-rule actions): Make sure the user can
16225 define YYDEBUG and YYERROR_VERBOSE.
16227 2001-12-29 Akim Demaille <akim@epita.fr>
16229 * src/output.c (header_output): Don't forget to export YYLTYPE and
16231 * tests/headers.at (export YYLTYPE): New, make sure it does.
16232 * tests/regression.at (%union and --defines, Invalid CPP headers):
16234 * tests/headers.at: here.
16236 2001-12-29 Akim Demaille <akim@epita.fr>
16238 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
16240 2001-12-29 Akim Demaille <akim@epita.fr>
16242 * tests/actions.at (Mid-rule actions): Output on a single line
16243 instead of several.
16245 2001-12-29 Akim Demaille <akim@epita.fr>
16247 * doc/bison.texinfo: Formatting changes.
16249 2001-12-29 Akim Demaille <akim@epita.fr>
16251 Don't store the token defs in a muscle, just be ready to output it
16252 on command. Now possible via `symbols'. Fixes a memory leak.
16254 * src/output.c (token_definitions_output): New.
16255 (output_parser, header_output): Use it.
16256 * src/reader.c (symbols_save): Remove.
16258 2001-12-29 Akim Demaille <akim@epita.fr>
16260 * src/bison.simple: Do not provide a default for YYSTYPE and
16261 YYLTYPE before the user's prologue. Otherwise it's hardly... a
16264 2001-12-29 Akim Demaille <akim@epita.fr>
16266 Mid-rule actions are simply... ignored!
16268 * src/reader.c (readgram): Be sure to attach mid-rule actions to
16269 the empty-rule associated to the dummy symbol, not to the host
16271 * tests/actions.at (Mid-rule actions): New.
16273 2001-12-29 Akim Demaille <akim@epita.fr>
16277 * src/reader.c (reader): Free grammar.
16279 2001-12-29 Akim Demaille <akim@epita.fr>
16283 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
16284 since it allocates it for each state, although only one is needed.
16285 (allocate_storage): Do it here.
16287 2001-12-29 Akim Demaille <akim@epita.fr>
16289 * src/options.h, src/options.c (create_long_option_table): Rename
16291 (long_option_table_new): this, with a clearer prototype.
16292 (percent_table): Remove, unused,
16293 * src/getargs.c (getargs): Adjust.
16295 2001-12-29 Akim Demaille <akim@epita.fr>
16297 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
16298 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
16301 2001-12-29 Akim Demaille <akim@epita.fr>
16303 * src/lalr.c (build_relations): Rename `states' as `states1'.
16304 Sorry, I don't understand exactly what it is, no better name...
16306 2001-12-29 Akim Demaille <akim@epita.fr>
16308 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
16309 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
16310 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
16313 2001-12-29 Akim Demaille <akim@epita.fr>
16315 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
16318 2001-12-29 Akim Demaille <akim@epita.fr>
16320 * src/reader.c, src/reader.h (user_toknums): Remove.
16321 Adjust all users to use symbols[i]->user_token_number.
16323 2001-12-29 Akim Demaille <akim@epita.fr>
16325 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
16326 Adjust all users to use symbols[i]->prec or ->assoc.
16328 2001-12-29 Akim Demaille <akim@epita.fr>
16330 * src/reader.c, src/reader.h (tags): Remove.
16331 Adjust all users to use symbols[i]->tag.
16333 2001-12-29 Akim Demaille <akim@epita.fr>
16335 * src/gram.h, src/gram.c (symbols): New, similar to state_table
16337 * src/reader.c (packsymbols): Fill this table.
16339 * src/conflicts.c (resolve_sr_conflict): Adjust.
16340 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
16342 Use symbols[i]->tag instead of tags[i].
16344 2001-12-29 Akim Demaille <akim@epita.fr>
16346 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
16347 In addition, put a comment in there, to replace...
16348 * tests/regression.at (%union and C comments): Remove.
16350 2001-12-29 Akim Demaille <akim@epita.fr>
16352 * tests/regression.at (Web2c Actions): Blindly move the actual
16353 output as expected output. The contents *seem* right to me, but I
16354 can't pretend reading perfectly parser tables... Nonetheless, all
16355 the other tests pass correctly, the table look OK, even though the
16356 presence of `$axiom' is to be noted: AFAICS it is useless (but
16359 2001-12-29 Akim Demaille <akim@epita.fr>
16361 * src/reader.c (readgram): Don't add the rule 0 if there were no
16362 rules read. In other words, add it _after_ having performed
16363 grammar sanity checks.
16364 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
16366 2001-12-29 Akim Demaille <akim@epita.fr>
16368 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
16369 visible, and some states have now a different number.
16371 2001-12-29 Akim Demaille <akim@epita.fr>
16373 * src/reader.c (readgram): Bind the initial rule's lineno to that
16375 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
16376 (Solved SR Conflicts): Adjust rule 0's line number.
16378 2001-12-29 Akim Demaille <akim@epita.fr>
16380 Fix the `GAWK Grammar' failure.
16382 * src/LR0.c (final_state): Initialize to -1 so that we do compute
16383 the reductions of the first state which was mistakenly confused
16384 with the final state because precisely final_state was initialized
16386 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
16387 now noticed by Bison.
16388 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
16389 have a reduction on $default.
16391 2001-12-29 Akim Demaille <akim@epita.fr>
16393 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
16395 * src/closure.c (print_closure): Likewise.
16396 * src/derives.c (print_derives): Likewise.
16397 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
16400 2001-12-29 Akim Demaille <akim@epita.fr>
16402 * src/lalr.c (lookaheads_print): New.
16403 (lalr): Call it when --trace-flag.
16404 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
16407 2001-12-29 Akim Demaille <akim@epita.fr>
16409 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
16410 when walking through ritem, even via rule->rhs.
16411 * src/reduce.c (dump_grammar, useful_production, reduce_output)
16412 (useful_production, useless_nonterminals): Likewise.
16413 (reduce_grammar_tables): Likewise, plus update nritems.
16414 * src/nullable.c (set_nullable): Likewise.
16415 * src/lalr.c (build_relations): Likewise.
16416 * tests/sets.at (Nullable): Adjust.
16417 Fortunately, now, the $axiom is no longer nullable.
16419 2001-12-29 Akim Demaille <akim@epita.fr>
16421 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
16423 * src/gram.c (ritem_longest_rhs): Likewise.
16424 * src/reduce.c (nonterminals_reduce): Likewise.
16425 * src/print_graph.c (print_graph): Likewise.
16426 * src/output.c (output_rule_data): Likewise.
16427 * src/nullable.c (set_nullable): Likewise.
16429 2001-12-29 Akim Demaille <akim@epita.fr>
16431 * src/output.c: Comment changes.
16433 2001-12-27 Paul Eggert <eggert@twinsun.com>
16435 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
16436 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
16437 Sparc, as they were causing more porting problems than the
16438 (minor) performance improvement was worth.
16440 Also, catch up with 1.31's YYSTD.
16442 2001-12-27 Akim Demaille <akim@epita.fr>
16444 * src/output.c (output_gram): Rely on nritems, not the
16445 0-sentinel. See below.
16446 Use -1 as separator, not 0.
16447 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
16448 Rely on -1 as separator in yyrhs, instead of 0.
16449 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
16450 twice `Now at end of input', therefore there are two lines less to
16453 2001-12-27 Akim Demaille <akim@epita.fr>
16455 * tests/regression.at (Unresolved SR Conflicts):
16456 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
16459 2001-12-27 Akim Demaille <akim@epita.fr>
16461 * src/LR0.c (new_state): Recognize the final state by the fact it
16462 is reached by eoftoken.
16463 (insert_start_shifting_state, insert_eof_shifting_state)
16464 (insert_accepting_state, augment_automaton): Remove, since now
16465 these states are automatically computed from the initial state.
16466 (generate_states): Adjust.
16467 * src/print.c: When reporting a rule number to the user, substract
16468 1, so that the axiom rule is rule 0, and the first user rule is 1.
16469 * src/reduce.c: Likewise.
16470 * src/print_graph.c (print_core): For the time being, just as for
16471 the report, depend upon --trace-flags to dump the full set of
16473 * src/reader.c (readgram): Once the grammar read, insert the rule
16474 0: `$axiom: START-SYMBOL $'.
16475 * tests/set.at: Adjust: rule 0 is now displayed, and since the
16476 number of the states has changed (the final state is no longer
16477 necessarily the last), catch up.
16479 2001-12-27 Akim Demaille <akim@epita.fr>
16481 Try to make the use of the eoftoken valid. Given that its value
16482 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
16483 is used instead of > 0 where appropriate, (ii), depend upon nritems
16484 instead of the 0-sentinel.
16486 * src/gram.h, src/gram.c (nritems): New.
16487 Expected to be duplication of nitems, but for the time being...
16488 * src/reader.c (packgram): Assert nritems and nitems are equal.
16489 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
16490 * src/closure.c (print_closure, print_fderives): Likewise.
16491 * src/gram.c (ritem_print): Likewise.
16492 * src/print.c (print_core, print_grammar): Likewise.
16493 * src/print_graph.c: Likewise.
16495 2001-12-27 Akim Demaille <akim@epita.fr>
16497 * src/main.c (main): If there are complains after grammar
16498 reductions, then output the report anyway if requested, then die.
16499 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
16500 * src/reader.c (eoftoken): New.
16501 (parse_token_decl): If the token being defined has value `0', it
16503 (packsymbols): No longer hack `tags' to insert `$' by hand.
16504 Be sure to preserve the value of the eoftoken.
16505 (reader): Make sure eoftoken is defined.
16506 Initialize nsyms to 0: now eoftoken is created just like the others.
16507 * src/print.c (print_grammar): Don't special case the eof token.
16508 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
16509 lie anyway, albeit pleasant.
16510 * tests/calc.at: Exercise error messages with eoftoken.
16511 Change the grammar so that empty input is invalid.
16512 Adjust expectations.
16513 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
16515 2001-12-27 Akim Demaille <akim@epita.fr>
16517 * configure.in: Check the protos of strchr ans strspn.
16518 Replace strchr if needed.
16519 * src/system.h: Provide the protos of strchr, strspn and memchr if
16521 * lib/strchr.c: New.
16522 * src/reader.c (symbols_save): Use strchr.
16524 2001-12-27 Akim Demaille <akim@epita.fr>
16526 * src/print.c, src/print_graph.c (escape): New.
16527 Use it to quote the TAGS outputs.
16528 * src/print_graph.c (print_state): Now errors are in red, and
16529 reductions in green.
16530 Prefer high to wide: output the state number on a line of its own.
16532 2001-12-27 Akim Demaille <akim@epita.fr>
16534 * src/state.h, src/state.c (reductions_new): New.
16535 * src/LR0.c (set_state_table): Let all the states have a
16536 `reductions', even if reduced to 0.
16537 (save_reductions): Adjust.
16538 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
16539 * src/print.c (print_reductions, print_actions): Adjust.
16540 * src/output.c (action_row): Adjust.
16542 2001-12-27 Akim Demaille <akim@epita.fr>
16544 * src/state.h, src/state.c (errs_new, errs_dup): New.
16545 * src/LR0.c (set_state_table): Let all the states have an errs,
16546 even if reduced to 0.
16547 * src/print.c (print_errs, print_reductions): Adjust.
16548 * src/output.c (output_actions, action_row): Adjust.
16549 * src/conflicts.c (resolve_sr_conflict): Adjust.
16551 2001-12-27 Akim Demaille <akim@epita.fr>
16553 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
16555 2001-12-27 Akim Demaille <akim@epita.fr>
16557 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
16558 * src/print.c: here.
16559 (lookaheadset, shiftset): New, used as additional storage by
16561 (print_results): Adjust.
16562 (print_shifts, print_gotos, print_errs): New, extracted from...
16563 (print_actions): here.
16564 * src/print_graph.c (print_actions): Remove dead code.
16566 2001-12-27 Akim Demaille <akim@epita.fr>
16568 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
16571 2001-12-27 Akim Demaille <akim@epita.fr>
16573 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
16574 (build_relations): Adjust.
16576 2001-12-27 Akim Demaille <akim@epita.fr>
16578 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
16581 2001-12-27 Akim Demaille <akim@epita.fr>
16583 * src/reader.c (packgram): Catch nitems overflows.
16585 2001-12-27 Akim Demaille <akim@epita.fr>
16587 * src/files.c, src/files.h (guard_obstack): Remove.
16588 * src/output.c (output): Adjust.
16589 * src/reader.c (parse_braces): New, factoring...
16590 (copy_action, copy_guard): these two which are renamed as...
16591 (parse_action, parse_guard): these.
16592 As a voluntary consequence, using braces around guards is now
16595 2001-12-27 Akim Demaille <akim@epita.fr>
16597 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
16598 * src/reader.c (symbol_list): `guard' and `guard_line' are new
16600 (symbol_list_new): Adjust.
16601 (copy_action): action_line is the first line, not the last.
16602 (copy_guard): Just as for actions, store the `action' only, not
16603 the switch/case/break flesh.
16604 Don't parse the user action that might follow the guard, let...
16605 (readgram): do it, i.e., now, there can be an action after a
16607 In other words the guard is just explicitly optional.
16608 (packgram): Adjust.
16609 * src/output.c (guards_output): New.
16610 (output_parser): Call it when needed.
16611 (output): Also free the guard and attrs obstacks.
16612 * src/files.c, src/files.h (obstack_save): Remove.
16613 (output_files): Remove.
16614 As a result, if one needs the former `.act' file, using an
16615 appropriate skeleton which requires actions and guards is now
16617 * src/main.c (main): Adjust.
16618 * tests/semantic.at: New.
16619 * tests/regression.at: Use `input.y' as input file name.
16620 Avoid 8+3 problems by requiring input.c when the test needs the
16623 2001-12-27 Akim Demaille <akim@epita.fr>
16625 * src/reader.c (symbol_list_new): Be sure to initialize all the
16628 2001-12-27 Akim Demaille <akim@epita.fr>
16630 All the hacks using a final pseudo state are now useless.
16632 * src/LR0.c (set_state_table): state_table holds exactly nstates.
16633 * src/lalr.c (nLA): New.
16634 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
16635 instead of lookaheadsp from the pseudo state (nstate + 1).
16637 2001-12-27 Akim Demaille <akim@epita.fr>
16639 * src/output.c (action_row, token_actions): Use a state_t instead
16640 of a integer, and nlookaheads instead of the following state's
16643 2001-12-27 Akim Demaille <akim@epita.fr>
16645 * src/conflicts.c (log_resolution, flush_shift)
16646 (resolve_sr_conflict, set_conflicts, solve_conflicts)
16647 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
16648 (conflicts_print, print_reductions): Use a state_t instead of an
16649 integer when referring to a state.
16650 As much as possible, depend upon nlookaheads, instead of the
16651 `lookaheadsp' member of the following state (since lookaheads of
16652 successive states are successive, the difference between state n + 1
16653 and n served as the number of lookaheads for state n).
16654 * src/lalr.c (add_lookback_edge): Likewise.
16655 * src/print.c (print_core, print_actions, print_state)
16656 (print_results): Likewise.
16657 * src/print_graph.c (print_core, print_actions, print_state)
16658 (print_graph): Likewise.
16659 * src/conflicts.h: Adjust.
16661 2001-12-27 Akim Demaille <akim@epita.fr>
16663 * src/bison.hairy: Formatting/comment changes.
16665 Remove `register' indications.
16666 Add plenty of `static'.
16668 2001-12-27 Akim Demaille <akim@epita.fr>
16670 * src/output.c (prepare): Drop the muscle `ntbase' which
16671 duplicates ntokens.
16672 * src/bison.simple: Formatting/comment changes.
16673 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
16674 is an undocumented synonym.
16676 2001-12-22 Akim Demaille <akim@epita.fr>
16678 * src/output.c (output_table_data): Change the prototype to use
16679 `int' for array ranges: some invocations do pass an int, not a
16681 Reported by Wayne Green.
16683 2001-12-22 Akim Demaille <akim@epita.fr>
16685 Some actions of web2c.y are improperly triggered.
16686 Reported by Mike Castle.
16688 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
16689 * tests/regression.at (Web2c): Rename as...
16690 (Web2c Report): this.
16691 (Web2c Actions): New.
16693 2001-12-22 Akim Demaille <akim@epita.fr>
16695 Reductions in web2c.y are improperly reported.
16696 Reported by Mike Castle.
16698 * src/conflicts.c (print_reductions): Fix.
16699 * tests/regression.at (Web2c): New.
16701 2001-12-18 Akim Demaille <akim@epita.fr>
16703 Some host fail on `assert (!"foo")', which expands to
16704 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
16705 Reported by Nelson Beebee.
16707 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
16708 `#define it_succeeded 0' and `assert (it_succeeded)'.
16710 2001-12-17 Marc Autret <autret_m@epita.fr>
16712 * src/bison.simple: Don't hard code the skeleton line and filename.
16713 * src/output.c (output_parser): Rename 'line' as 'output_line'.
16714 New line counter 'skeleton_line' (skeleton-line muscle).
16716 2001-12-17 Paul Eggert <eggert@twinsun.com>
16718 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
16719 YYDEBUG must be defined to a nonzero value.
16721 * src/bison.simple (yytname): Do not assume that the user defines
16722 YYDEBUG to a properly parenthesized expression.
16724 2001-12-17 Akim Demaille <akim@epita.fr>
16726 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
16727 nlookaheads is a new member.
16729 * src/lalr.h (nlookaheads): Remove this orphan declaration.
16730 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
16733 2001-12-17 Akim Demaille <akim@epita.fr>
16735 * src/files.h, src/files.c (open_files, close_files): Remove.
16736 * src/main.c (main): Don't open/close files, nor invoke lex_free,
16738 * src/reader.c (reader): Do it.
16740 2001-12-17 Akim Demaille <akim@epita.fr>
16742 * src/conflicts.c (print_reductions): Formatting changes.
16744 2001-12-17 Akim Demaille <akim@epita.fr>
16746 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
16747 (flush_reduce): New.
16748 (resolve_sr_conflict): Adjust.
16750 2001-12-17 Akim Demaille <akim@epita.fr>
16752 * src/output.c (output_obstack): Be static and rename as...
16753 (format_obstack): this, to avoid any confusion with files.c's
16755 * src/reader.h (muscle_obstack): Move to...
16756 * src/output.h: here, since it's defined in output.c.
16758 2001-12-17 Akim Demaille <akim@epita.fr>
16760 * src/output.c (action_row, save_column, default_goto)
16761 (sort_actions, matching_state, pack_vector): Better variable
16764 2001-12-17 Akim Demaille <akim@epita.fr>
16766 * src/output.c: Various formatting changes.
16768 2001-12-17 Akim Demaille <akim@epita.fr>
16770 * src/files.c (output_files): Free the output_obstack.
16771 * src/main.c (main): Call print and print_graph conditionally.
16772 * src/print.c (print): Work unconditionally.
16773 * src/print_graph.c (print_graph): Work unconditionally.
16774 * src/conflicts.c (log_resolution): Output only if verbose_flag.
16776 2001-12-16 Marc Autret <autret_m@epita.fr>
16778 * src/output.c (actions_output): Fix. When we use %no-lines,
16779 there is one less line per action.
16781 2001-12-16 Marc Autret <autret_m@epita.fr>
16783 * src/bison.simple: Remove a useless #line directive.
16784 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
16785 * src/output.c (get_lines_number): New.
16786 (output_parser): Adjust, now takes care about the lines of a
16788 Fix line numbering.
16789 (actions_output): Computes the number of lines taken by actions.
16790 (output_master_parser): Insert new skeleton which is the name of
16791 the output parser file name.
16793 2001-12-15 Marc Autret <autret_m@epita.fr>
16795 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
16797 2001-12-15 Marc Autret <autret_m@epita.fr>
16799 * src/output.c (output_gram): Keep track of the hairy one.
16801 2001-12-15 Akim Demaille <akim@epita.fr>
16803 Make `make distcheck' work.
16805 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
16806 system.h which uses libgettext.h.
16808 2001-12-15 Akim Demaille <akim@epita.fr>
16810 * src/nullable.c (set_nullable): Useless rules must be skipped,
16811 otherwise, since we range over their symbols, we might look at a
16812 nonterminal which no longer ``exists'', i.e., it is not counted in
16813 `nvars', hence we overflow our arrays.
16815 2001-12-15 Akim Demaille <akim@epita.fr>
16817 The header can also be produced directly, without any obstack!
16820 * src/files.c, src/files.h (defines_obstack): Remove.
16821 (compute_header_macro): Global.
16822 (defines_obstack_save): Remove.
16823 * src/reader.c (parse_union_decl): No longer output to
16824 defines_obstack: its content can be found in the `stype' muscle
16826 (output_token_translations): Merge into...
16827 (symbols_output): this.
16829 (symbols_save): this.
16831 * src/output.c (header_output): New.
16834 2001-12-15 Akim Demaille <akim@epita.fr>
16836 * src/reader.c (parse_union_decl): Instead of handling two obstack
16837 simultaneously, use one to define the `stype' muscle, and use the
16838 value of the latter to fill defines_obstack.
16839 (copy_comment): Remove.
16840 (copy_comment2): Work for a single obstack.
16842 (copy_comment): this.
16844 2001-12-15 Akim Demaille <akim@epita.fr>
16846 * src/lex.c, src/lex.h (xgetc): No longer static.
16847 * src/reader.c (parse_union_decl): Revamp.
16849 2001-12-15 Akim Demaille <akim@epita.fr>
16851 Still making progress in separating Bison into (i) input, (ii)
16852 process, (iii) output: now we can directly output the parser file
16853 without using table_obstack at all.
16855 * src/files.c, src/files.h (table_obstack): Bye bye.
16856 (parser_file_name): New.
16857 * src/files.c (compute_output_file_names): Compute it.
16858 * src/output.c (actions_output, output_parser)
16859 (output_master_parser): To a file instead of an obstack.
16861 2001-12-15 Akim Demaille <akim@epita.fr>
16863 Attach actions to rules, instead of pre-outputting them to
16866 * src/gram.h (rule_t): action and action_line are new members.
16867 * src/reader.c (symbol_list): Likewise.
16868 (copy_action): Save the actions within the rule.
16869 (packgram): Save them in rule_table.
16870 * src/output.c (actions_output): New.
16871 (output_parser): Use it on `%%actions'.
16872 (output_rule_data): Don't free rule_table.
16874 (prepare): Don't save the `action' muscle.
16875 * src/bison.simple: s/%%action/%%actions/.
16877 2001-12-15 Akim Demaille <akim@epita.fr>
16879 * src/reader.c (copy_action): When --yacc, don't append a `;'
16880 to the user action: let it fail if lacking.
16881 Suggested by Arnold Robbins and Tom Tromey.
16883 2001-12-14 Akim Demaille <akim@epita.fr>
16885 * src/lex.c (literalchar): Simply return the char you decoded, non
16886 longer mess around with obstacks and int pointers.
16887 Adjust all callers.
16889 2001-12-14 Akim Demaille <akim@epita.fr>
16891 * src/lex.c (literalchar): Don't escape the special characters,
16892 just decode them, and keep them as char (before, eol was output as
16893 the 2 char string `\n' etc.).
16894 * src/output.c (output_rule_data): Use quotearg to output the
16897 2001-12-13 Paul Eggert <eggert@twinsun.com>
16899 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
16900 Do not infringe on the global user namespace when using C++.
16901 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
16902 All uses of `fprintf' and `stderr' changed.
16904 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
16906 2001-12-13 Akim Demaille <akim@epita.fr>
16908 The computation of nullable is broken: it doesn't handle empty
16911 * tests/torture.at (GNU AWK Grammar): New.
16912 * tests/sets.at (Nullable): New.
16913 * src/nullable.c (set_nullable): Instead of blindly looping over
16914 `ritems', loop over the rules, and then over their rhs's.
16916 Work around Autotest bugs.
16918 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
16919 frame, because Autotest understand lines starting with a `+' as
16920 traces from the shell. Then, they are not processed properly.
16921 Admittedly an Autotest bug, but we don't have time to wait for
16922 Autotest to catch up.
16923 * tests/regression.at (Broken Closure): Adjust to the new table
16926 * tests/sets.at: here.
16928 2001-12-13 Akim Demaille <akim@epita.fr>
16930 * src/closure.c (closure): Use nrules instead of playing tricks
16931 with BITS_PER_WORD.
16933 2001-12-13 Akim Demaille <akim@epita.fr>
16935 * src/print.c (print_actions): Output the handling of `$' as the
16936 traces do: shifting the token EOF. Before EOF was treated as a
16938 * tests/regression.at: Adjust some tests.
16939 * src/print_graph.c (print_core): Complete the set of items via
16940 closure. The next-to-final and final states are still unsatisfying,
16941 but that's to be addressed elsewhere.
16942 No longer output the rule numbers, but do output the state number.
16943 A single loop for the shifts + gotos is enough, but picked a
16944 distinct color for each.
16945 (print_graph): Initialize and finalize closure.
16947 2001-12-13 Akim Demaille <akim@epita.fr>
16949 * src/reader.c (readgram): Remove dead code, an strip useless
16951 (get_type): Remove, unused.
16953 2001-12-12 Akim Demaille <akim@epita.fr>
16955 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
16956 on that of lib/error.c.
16958 2001-12-12 Akim Demaille <akim@epita.fr>
16960 Some hosts don't like `/' in includes.
16962 * src/system.h: Include libgettext.h without qualifying the path.
16963 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
16966 2001-12-11 Marc Autret <autret_m@epita.fr>
16968 * src/output.c (output_parser): Remove useless muscle.
16970 2001-12-11 Marc Autret <autret_m@epita.fr>
16972 * src/bison.simple: Remove #line just before %%epilogue. It
16973 is now handled in ...
16974 * src/reader.c (read_additionnal_code): Add the output of a
16975 #line for the epilogue.
16977 2001-12-10 Marc Autret <autret_m@epita.fr>
16979 * src/reader.c (copy_definition): Re-use CPP-outed code which
16980 replace precedent remove.
16981 * src/bison.simple: Remove #line before %%prologue because
16982 %%input-line is wrong at this time.
16984 2001-12-10 Marc Autret <autret_m@epita.fr>
16986 * src/reader.c (symbols_output): Clean up.
16987 * src/output.c (output_gram, output): Clean up.
16989 2001-12-10 Akim Demaille <akim@epita.fr>
16991 * src/lalr.c (initialize_lookaheads): New. Extracted from...
16992 * src/LR0.c (set_state_table): here.
16993 * src/lalr.c (lalr): Call it.
16995 2001-12-10 Akim Demaille <akim@epita.fr>
16997 * src/state.h (shifts): Remove the `number' member: shifts are
16998 attached to state, hence no longer need to be labelled with a
17001 2001-12-10 Akim Demaille <akim@epita.fr>
17003 Now that states have a complete set of members, the linked list of
17004 shifts is useless: just fill directly the state's shifts member.
17006 * src/state.h (shifts): Remove the `next' member.
17007 * src/LR0.c (first_state, last_state): Remove.
17008 Adjust the callers.
17009 (augment_automaton): Don't look for the shifts that must be added
17010 a shift on EOF: it is those of the state we looked for! But now,
17011 since shifts are attached, it is no longer needed to looking
17012 merely by its id: its number.
17014 2001-12-10 Akim Demaille <akim@epita.fr>
17016 * src/LR0.c (augment_automaton): Better variable locality.
17017 Remove an impossible branch: if there is a state corresponding to
17018 the start symbol being shifted, then there is shift for the start
17019 symbol from the initial state.
17021 2001-12-10 Akim Demaille <akim@epita.fr>
17023 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
17024 only when appropriate: when insert_start_shifting_state' is not
17026 * tests/regression.at (Rule Line Numbers): Adjust.
17028 2001-12-10 Akim Demaille <akim@epita.fr>
17030 * src/LR0.c (augment_automaton): Now that all states have shifts,
17031 merge the two cases addition shifts to the initial state.
17033 2001-12-10 Akim Demaille <akim@epita.fr>
17035 * src/lalr.c (set_state_table): Move to...
17037 * src/lalr.c (lalr): Don't call it...
17038 * src/LR0.c (generate_states): do it.
17039 * src/LR0.h (first_state): Remove, only the table is used.
17041 2001-12-10 Akim Demaille <akim@epita.fr>
17043 * src/LR0.h (first_shift, first_reduction): Remove.
17044 * src/lalr.c: Don't use first_shift: find shifts through the
17047 2001-12-10 Akim Demaille <akim@epita.fr>
17049 * src/LR0.c: Attach shifts to states as soon as they are
17051 * src/lalr.c (set_state_table): Instead of assigning shifts to
17052 state, just assert that the mapping was properly done.
17054 2001-12-10 Akim Demaille <akim@epita.fr>
17056 * src/LR0.c (insert_start_shift): Rename as...
17057 (insert_start_shifting_state): this.
17058 (insert_eof_shifting_state, insert_accepting_state): New.
17059 (augment_automaton): Adjust.
17060 Better locality of the variables.
17061 When looking if the start_symbol is shifted from the initial
17062 state, using `while (... symbol != start_symbol ...)' sounds
17063 better than `while (... symbol < start_symbol ...)': If fail
17064 to see how the order between symbols could be relevant!
17066 2001-12-10 Akim Demaille <akim@epita.fr>
17068 * src/getargs.h: Don't declare `spec_name_prefix' and
17069 `spec_file_prefix', declared by src/files.h.
17070 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
17071 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
17072 * src/output.c (prepare): Adjust.
17073 * src/reader.c (symbols_output): Likewise.

17076 2001-12-10 Akim Demaille <akim@epita.fr>
17078 * src/muscle_tab.c (muscle_init): NULL is a better default than
17081 2001-12-10 Akim Demaille <akim@epita.fr>
17083 * src/reader.c (reader): Calling symbols_output once is enough.
17085 2001-12-10 Akim Demaille <akim@epita.fr>
17087 Now that states have a complete set of members, the linked list of
17088 reductions is useless: just fill directly the state's reductions
17091 * src/state.h (struct reductions): Remove member `number' and
17093 * src/LR0.c (first_reduction, last_reduction): Remove.
17094 (save_reductions): Don't link the new reductions, store them in
17096 * src/lalr.c (set_state_table): No need to attach reductions to
17097 states, it's already done.
17098 * src/output.c (output_actions): No longer free the shifts, then
17099 the reductions, then the states: free all the states and their
17102 2001-12-10 Akim Demaille <akim@epita.fr>
17104 * src/options.c (OPTN, DRTV, BOTH): New.
17105 (option_table): Use them.
17107 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
17108 the job of system.h.
17109 * src/options.c: Don't include stdio.h and xalloc.h for the same
17112 2001-12-10 Akim Demaille <akim@epita.fr>
17114 * src/output.c (output, prepare): Make sure the values of the
17115 muscles `action' and `prologue' are 0-terminated.
17117 2001-12-10 Akim Demaille <akim@epita.fr>
17119 Clean up GCC warnings.
17121 * src/reader.c (copy_action): `buf' is not used.
17122 (parse_skel_decl): Be static.
17123 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
17124 * src/options.h (create_long_option_table): Have a real prototype.
17125 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)

17127 Adjust casts to preserve the const.
17129 2001-12-10 Akim Demaille <akim@epita.fr>
17131 * configure.in: Require 2.52g.
17132 M4 is not needed, but AUTOM4TE is.
17133 * m4/m4.m4: Remove.
17134 * tests/Makefile.am: Adjust.
17136 2001-12-10 Akim Demaille <akim@epita.fr>
17138 One structure for states is enough, even though theoretically
17139 there are LR(0) states and LALR(1) states.
17141 * src/lalr.h (state_t): Remove.
17142 (state_table): Be state_t **, not state_t *.
17143 * src/state.h (core, CORE_ALLOC): Rename as...
17144 (state_t, STATE_ALLOC): this.
17145 Add the LALR(1) members: shifts, reductions, errs.
17146 * src/LR0.c (state_table): Rename as...
17147 (state_hash): this, to avoid name clashes with the global
17149 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
17150 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
17152 2001-12-10 Akim Demaille <akim@epita.fr>
17154 Bison dumps core on bash.y.
17155 Reported by Pascal Bart.
17157 * src/warshall.c (bitmatrix_print): New.
17159 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
17160 j must be the outer loop.
17161 * tests/regression.at (Broken Closure): New.
17163 2001-12-05 Akim Demaille <akim@epita.fr>
17165 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
17167 Reported by Peter Hamorsky.
17169 2001-12-05 Akim Demaille <akim@epita.fr>

17172 (resolve_sr_conflict): Adjust.
17173 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
17175 (state_t.reductions, state_t.shifts): this.
17177 2001-12-05 Akim Demaille <akim@epita.fr>
17179 * src/reduce.c (reduce_grammar_tables): No longer disable the
17180 removal of useless rules via CPP but via `if (0)', so that the
17181 compiler still check the code is valid.
17182 For instance, it should have noticed `rline' no longer exists: use
17183 the `line' member of rule_t.
17184 * src/gram.c (dummy, rline): Remove, unused.
17186 2001-12-05 Akim Demaille <akim@epita.fr>
17188 * src/output.c (pack_vector): Use assert, not berror.
17189 * src/main.c (berror): Remove, unused.
17191 2001-12-05 Akim Demaille <akim@epita.fr>
17193 New experimental feature: if --verbose --trace output all the
17194 items of a state, not only its kernel.
17196 * src/print.c (print_core): If `trace_flag', then invoke closure
17197 before outputting the items of the state (print_core is no longer
17198 a correct name them).
17199 (print_results): Invoke new_closure/free_closure if needed.
17201 2001-12-05 Akim Demaille <akim@epita.fr>
17203 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
17204 * src/closure.c, src/closure.h (itemsetsize): Rename as...
17205 (nitemset): for consistency with the rest of the project.
17207 2001-12-05 Akim Demaille <akim@epita.fr>
17209 * src/closure.c (print_closure): Improve.
17210 (closure): Use it for printing input and output.
17212 2001-12-05 Akim Demaille <akim@epita.fr>
17214 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
17215 indexed by nonterminals.
17217 2001-12-05 Akim Demaille <akim@epita.fr>
17219 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
17221 * src/warshall.h: Remove accidental duplication of the content.
17223 2001-12-05 Akim Demaille <akim@epita.fr>

17235 2001-12-05 Akim Demaille <akim@epita.fr>
17237 * src/output.c (action_row): De-obfuscate
17238 using the good o' techniques: arrays not pointers, variable
17239 locality, BITISSET, RESETBIT etc.
17241 2001-12-05 Akim Demaille <akim@epita.fr>
17243 Pessimize the code to simplify it: from now on, all the states
17244 have a valid SHIFTS, which NSHIFTS is possibly 0.
17246 * src/LR0.c (shifts_new): Be global and move to..
17247 * src/state.c, src/state.h: here.
17248 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
17249 * src/print_graph: Adjust.
17251 2001-12-05 Akim Demaille <akim@epita.fr>
17253 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
17254 * src/conflicts.c: Use it.
17255 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
17256 incorrectly ``simplified''.
17258 2001-12-05 Akim Demaille <akim@epita.fr>
17260 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
17261 using the good o' techniques: arrays not pointers, variable
17262 locality, BITISSET, RESETBIT etc.
17264 2001-12-05 Akim Demaille <akim@epita.fr>
17266 * src/state.h (SHIFT_SYMBOL): New.
17267 * src/conflicts.c: Use it to deobfuscate.
17269 2001-12-05 Akim Demaille <akim@epita.fr>
17271 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
17272 (print_reductions): De-obfuscate using the good o' techniques:
17273 arrays not pointers, variable locality, BITISSET.
17275 2001-12-05 Akim Demaille <akim@epita.fr>
17277 * src/conflicts.c (print_reductions): Arrays, not pointers.

17288 2001-12-05 Akim Demaille <akim@epita.fr>
17290 * src/conflicts.c (print_reductions): Pessimize, but clarify.
17292 2001-12-05 Akim Demaille <akim@epita.fr>
17294 * src/conflicts.c (print_reductions): Improve variable locality.
17296 2001-12-05 Akim Demaille <akim@epita.fr>
17298 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
17299 * src/lalr.c: Use them.
17301 2001-12-05 Akim Demaille <akim@epita.fr>
17303 * src/LR0.c (augment_automaton): Formatting changes.
17304 Better variable locality.
17306 2001-12-05 Akim Demaille <akim@epita.fr>
17308 * src/lalr.c (matrix_print): New.
17309 (transpose): Use it.
17310 Use arrays instead of pointers.
17312 2001-12-05 Akim Demaille <akim@epita.fr>
17314 * src/lalr.c (maxrhs): Move to...
17315 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
17316 * src/lalr.c (build_relations): Adjust.
17318 2001-12-05 Akim Demaille <akim@epita.fr>
17320 * src/lalr.c (transpose): Free the memory allocated to the
17321 argument, as it is replaced by the results by the unique caller.
17322 (build_relations): Merely invoke transpose: it handles the memory
17324 Improve variable locality.
17325 Avoid variables used as mere abbreviations.
17326 (compute_lookaheads): Use arrays instead of pointers.
17328 2001-12-05 Akim Demaille <akim@epita.fr>
17330 * src/lalr.c (initialize_F): Improve variable locality.
17331 Avoid variables used as mere abbreviations.
17333 2001-12-05 Akim Demaille <akim@epita.fr>
17335 * src/derives.c (print_derives): Display the ruleno.
17336 * src/lalr.c (initialize_F, transpose): Better variable locality

17342 * src/lalr.c (traverse): Use arrays instead of pointers.
17344 2001-12-05 Akim Demaille <akim@epita.fr>
17346 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
17347 the handling of squeue.
17348 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17350 2001-12-05 Akim Demaille <akim@epita.fr>
17352 Because useless nonterminals are now kept alive (instead of being
17353 `destroyed'), we now sometimes examine them, and store information
17354 related to them. Hence we need to know their number, and adjust
17355 memory allocations.
17357 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
17359 * src/LR0.c (allocate_itemsets): The memory allocated to
17360 `symbol_count' was used for two different purpose: once to count
17361 the number of occurrences of each symbol, and later reassigned to
17362 `shift_symbol', containing the symbol that can be shifted from a
17364 Deobfuscate, i.e., allocate, use and free `symbol_count' here
17366 (new_itemsets): Allocate `shift_symbol' here.
17367 (allocate_itemsets): symbol_count includes useless nonterminals.
17368 Make room for them.
17369 (free_storage): Use `free', not `XFREE', for pointers that cannot
17372 2001-12-05 Akim Demaille <akim@epita.fr>
17374 * src/nullable.c (set_nullable): Deobfuscate the handling of
17376 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17378 2001-12-05 Akim Demaille <akim@epita.fr>
17380 * src/gram.c, src/gram.h (ritem_print): New.
17381 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
17382 (This useless function was defined only to work around VMS linkers
17383 that can't handle compilation units with variables only).
17384 * src/reduce.c (dump_grammar): Use it to trace the construction of
17387 2001-12-04 Paul Eggert <eggert@twinsun.com>
17389 * src/bison.simple (union yyalloc): Change member names
17390 to be the same as the stack names.
17391 (yyparse): yyptr is now union yyalloc *, not char *.
17392 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
17393 and may generate better code on some machines.
17394 (yystpcpy): Use prototype if __STDC__ is defined, not just
17395 if __cplusplus is defined.
17397 2001-11-30 Akim Demaille <akim@epita.fr>
17399 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
17400 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
17401 Gettext doesn't compile cleanly, and dies with -Werror.
17402 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
17403 Include WARNING_CFLAGS here.
17404 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
17405 before being defined.
17407 2001-11-27 Paul Eggert <eggert@twinsun.com>
17409 * lib/quotearg.h (quotearg_n, quotearg_n_style):
17410 First arg is int, not unsigned.
17411 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
17412 (SIZE_MAX, UINT_MAX): New macros.
17413 (quotearg_n_options): Abort if N is negative.
17414 Avoid overflow check on hosts where size_t is 64 bits and int
17415 is 32 bits, as overflow is impossible there.
17416 Fix off-by-one typo that caused unnecessary reallocation.
17418 2001-11-29 Paul Eggert <eggert@twinsun.com>
17420 Name space cleanup in generated parser.
17422 * doc/bison.texinfo (Bison Parser): Discuss system headers
17423 and their effect on the user name space.
17425 * src/bison.simple:
17426 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
17427 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
17428 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
17430 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
17431 on user names when possible.
17433 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
17434 Simplify test for whather <alloca.h> exists.
17436 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
17438 (<stdio.h>): Include if YYDEBUG.
17440 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
17441 ! defined (yyoverflow) && ! defined (yymemcpy).
17443 (yymemcpy, yyparse): Rename local variables as needed so that
17444 they all begin with 'yy'.
17446 (yystrlen, yystpcpy): New functions.
17448 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
17451 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
17452 instead of relying on string.h functions. Use YYSTACK_ALLOC
17453 and YYSTACK_FREE instead of malloc and free.
17455 2001-11-30 Akim Demaille <akim@epita.fr>
17457 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
17458 before their first uses.
17459 (YYBISON, YYPURE): Move to the top of the output.
17461 2001-11-30 Akim Demaille <akim@epita.fr>
17463 * tests/reduce.at (Useless Nonterminals): Fix.
17465 2001-11-30 Akim Demaille <akim@epita.fr>
17467 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
17468 if body instead of `;' to pacify GCC's warnings.
17470 2001-11-30 Akim Demaille <akim@epita.fr>
17472 Instead of mapping the LHS of unused rules to -1, keep the LHS
17473 valid, but flag the rules as invalid.
17475 * src/gram.h (rule_t): `useful' is a new member.
17476 * src/print.c (print_grammar): Adjust.
17477 * src/derives.c (set_derives): Likewise.
17478 * src/reader.c (packgram, reduce_output): Likewise.
17479 * src/reduce.c (reduce_grammar_tables): Likewise.
17480 * tests/reduce.at (Underivable Rules, Useless Rules): New.
17482 2001-11-30 Akim Demaille <akim@epita.fr>
17484 * src/reduce.c (reduce_output): Formatting changes.
17485 * src/print.c (print_results, print_grammar): Likewise.
17486 * tests/regression.at (Rule Line Numbers)
17487 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
17489 2001-11-30 Akim Demaille <akim@epita.fr>
17491 * src/reduce.c (nonterminals_reduce): Instead of throwing away
17492 useless nonterminals, move them at the end of the symbol arrays.
17493 (reduce_output): Adjust.
17494 * tests/reduce.at (Useless Nonterminals): Adjust.
17496 2001-11-30 Akim Demaille <akim@epita.fr>
17498 * src/reduce.c: Various comment/formatting changes.
17499 (nonterminals_reduce): New, extracted from...
17500 (reduce_grammar_tables): here.
17501 (reduce_grammar): Call nonterminals_reduce.
17503 2001-11-29 Paul Eggert <eggert@twinsun.com>
17505 * src/bison.simple (YYSTACK_REALLOC): Remove.
17506 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
17507 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
17509 (union yyalloc): New type.
17510 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
17511 an arbitrary restriction on hosts where size_t is wider than int.
17513 (yyparse): Don't dump core if alloca or malloc fails; instead, report
17514 a parser stack overflow. Allocate just one block of memory for all
17515 three stacks, instead of allocating three blocks; this typically is
17516 faster and reduces fragmentation.
17518 Do not limit the number of items in the stack to a value that fits
17519 in 'int', as this is an arbitrary limit on hosts with 64-bit
17520 size_t and 32-bit int.
17522 2001-11-29 Marc Autret <autret_m@epita.fr>
17524 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
17525 of defining YYERROR_VERBOSE.
17526 [AT_DATA]: $4 is now out of C declarations in the prologue.
17528 2001-11-28 Marc Autret <autret_m@epita.fr>

17533 * src/lex.c (literalchar): Become not static.
17535 2001-11-28 Marc Autret <autret_m@epita.fr>
17537 * src/output.h: And put its extern declaration here.
17538 * src/output.c (error_verbose): Define here.
17539 (prepare): Echo name modification.
17540 * src/getargs.h: Clean its extern declaration.
17541 * src/getargs.c (error_verbose_flag): Remove.
17542 (getargs): Remove case 'e'.

17570 2001-11-28 Akim Demaille <akim@epita.fr>
17572 * src/closure.c (closure): `b' and `ruleno' denote the same value:
17575 2001-11-28 Akim Demaille <akim@epita.fr>
17577 * src/closure.c (closure): Instead of looping over word in array
17578 then bits in words, loop over bits in array.

19332 New, from fileutils 4.0.37.
19333 * configure.in: Require Autoconf 2.49c. I took some time before

19357 s/\bENDFILE\b/tok_eof/g;

19384 introduces a guaranteed SEGV for semantic parsers.
19385 * doc/bison.texinfo: Document them.
19386 * tests/suite.at: Exercise these %options.

19457 * src/bison.hairy: Likewise.

19605 (output_files): this.
19606 Use `obstack_save'.
19607 * src/main.c (main): Don't use `atexit' to register `done', since
19608 it no longer has to remove tmp files, just call `output_files'
19609 when there are no errors.
19611 2000-11-02 Akim Demaille <akim@epita.fr>

19681 * src/reader.c (copy_comment2): Expect the input stream to be on
19682 the `/' which is suspected to open a comment, instead of being
19683 called after `//' or `/*' was read.
19684 (copy_comment, copy_definition, parse_union_decl, copy_action)
19685 (copy_guard): Adjust.
19687 2000-10-16 Akim Demaille <akim@epita.fr>
19689 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

19701 New files, from Fileutils 4.0.27.
19702 * src/main.c (printable_version): Remove.

19713 2000-10-04 Akim Demaille <akim@epita.fr>
19715 When a literal string is used to define two different tokens,
19716 `bison -v' segfaults.
19717 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
19719 * tests/regression.m4: New file.
19720 Include the core of the sample provided by Piotr Gackiewicz.
19721 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
19724 2000-10-04 Akim Demaille <akim@epita.fr>
19726 * src/reader.c (parse_expect_decl): Keep `count' within the size
19730 2000-10-02 Paul Eggert <eggert@twinsun.com>

19738 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
19741 2000-10-02 Akim Demaille <akim@epita.fr>
19743 * src/derives.c, src/print.c, src/reduce.c: To ease the
19744 translation, move some `\n' out of the translated strings.
19746 2000-10-02 Akim Demaille <akim@epita.fr>
19748 The location tracking mechanism is precious for parse error
19749 messages. Nevertheless, it is enabled only when `@n' is used in
19750 the grammar, which is a different issue (you can use it in error
19751 message, but not in the grammar per se). Therefore, there should
19752 be another means to enable it.
19754 * src/getargs.c (getargs): Support `--locations'.
19755 (usage): Report it.
19756 * src/getargs.h (locationsflag): Export it.
19757 * src/lex.c (percent_table): Support `%locations'.
19758 * src/reader.c (yylsp_needed): Remove this variable, now replaced
19759 with `locationsflag'.
19760 * doc/bison.texinfo: Document `--locations' and `%locations'.
19762 * tests/calc.m4: Test it.
19764 For regularity of the names, replace each
19765 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
19766 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
19767 In addition replace each `flag' with `_flag'.
19769 2000-10-02 Akim Demaille <akim@epita.fr>
19771 Also test parse error messages, including with YYERROR_VERBOSE.
19773 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
19775 Use it to check the computations.
19776 Use it to check `nonassoc' is honored.
19777 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
19778 `--yyerror-verbose'.

19782 2000-10-02 Akim Demaille <akim@epita.fr>
19784 Test also `--verbose', `--defines' and `--name-prefix'. Testing
19785 the latter demonstrates a flaw in the handling of non debugging
19786 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
19787 was used in order to simplify:
19803 unfortunately this leads to a CPP conflict when
19804 `--name-prefix=foo' is used since it produces `#define yydebug
19807 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
19808 (YYDPRINTF): New macro.
19810 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
19812 Also test `--verbose', `--defines' and `--name-prefix'.

19816 Improve the readability of the produced parsers.
19818 * src/bison.s1: Formatting changes.
19819 Improve the comment related to the `$' mark.
19820 (yydefault): Don't fall through to `yyresume': `goto' there.
19821 * src/output.c (output_parser): When the `$' is met, skip the end
19823 New variable, `number_of_dollar_signs', to check there's exactly
19824 one `$' in the parser skeleton.
19826 2000-10-02 Akim Demaille <akim@epita.fr>
19828 * lib/xstrdup.c: New file, from the fileutils.
19829 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
19830 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
19831 instead of strlen + xmalloc + strcpy.
19832 * src/symtab.c (copys): Remove, use xstrdup instead.
19834 2000-10-02 Akim Demaille <akim@epita.fr>
19836 * src/gram.h (associativity): New enum type which replaces the
19837 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
19838 `right_assoc', `left_assoc' and `non_assoc'.
19839 Adjust all dependencies.
19840 * src/reader.c: Formatting changes.
19841 (LTYPESTR): Don't define it, use it as a literal in
19842 `reader_output_yylsp'.
19843 * src/symtab.h (symbol_class): New enum type which replaces the
19844 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
19845 `sunknown', `stoken and `snterm'.
19847 2000-10-02 Akim Demaille <akim@epita.fr>
19849 * src/getargs.c (fixed_outfiles): Rename as...
19850 (yaccflag): for consistency and accuracy.
19851 Adjust dependencies.
19853 2000-10-02 Akim Demaille <akim@epita.fr>
19855 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
19856 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
19857 difficult and introduced a lot of core dump. It turns out that
19858 Bison used an implementation of `xmalloc' based on `calloc', and
19859 at various places it does depend upon the initialization to 0. I
19860 have not tried to isolate the pertinent places, and all the former
19861 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
19862 someone should address this issue.
19864 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
19865 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

19875 * src/system.h: Include `assert.h'.
19877 2000-10-02 Akim Demaille <akim@epita.fr>
19879 * src/state.h (nstates, final_state, first_state, first_shift)
19880 (first_reduction): Move their exportation from here...

19882 Adjust dependencies.
19883 * src/getargs.c (statisticsflag): New variable.
19884 Add support for `--statistics'.

19921 Propagate its inclusion.
19922 * src/reduce.c: Topological sort and other formatting changes.
19923 (bool, TRUE, FALSE): Move their definition to...
19924 * src/system.h: here.
19926 2000-10-02 Akim Demaille <akim@epita.fr>
19928 * src/files.c: Formatting changes.
19929 (tryopen, tryclose, openfiles): Rename as...
19930 (xfopen, xfclose, open_files): this.

19959 * src/output.c (token_actions): Introduce a temporary array,
19960 YYDEFACT, that makes it possible for this function to use
19961 output_short_table.
19963 2000-10-02 Akim Demaille <akim@epita.fr>
19965 `user_toknums' is output as a `short[]' in `output.c', while it is
19966 defined as a `int[]' in `reader.c'. For consistency with the
19967 other output tables, `user_toknums' is now defined as a table of

20207 2000-03-17 Akim Demaille <akim@epita.fr>
20209 * src/reader.c (copy_string): Declare `static inline'. No
20210 problems with inline, since it is checked by configure.

20230 2000-03-17 Akim Demaille <akim@epita.fr>
20232 Change the handling of @s so that they behave exactly like $s.
20233 There is now a pseudo variable @$ (readble and writable), location
20234 of the lhs of the rule (by default ranging from the location of
20235 the first symbol of the rhs, to the location of the last symbol,
20236 or, if the rhs is empty, YYLLOC).
20238 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
20240 (yyparse): When providing a default semantic action, provide a
20241 default location action.
20242 (after the $): No longer change `*YYLSP', just stack YYLOC the
20243 same way you stack YYVAL.
20244 * src/reader.c (read_declarations): Use warns.
20245 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

20268 2000-03-16 Akim Demaille <akim@epita.fr>
20270 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
20271 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
20272 One `#if YYDEBUG' remains, since it uses variables which are
20273 defined only if `YYDEBUG != 0'.
20275 2000-03-16 Akim Demaille <akim@epita.fr>
20277 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

20297 Bump to bison 1.28a, 1.29 has never been released.
20298 * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
20299 handled via src/Makefile.am.

20944 * src/reader.c (reader_output_yylsp):
20946 (readgram): Use `#if 0' around code that accepted %command
20947 inside grammar rules: The documentation doesn't allow it,
20948 and it will fail since the %command processors scan for the next %.

20950 declaration to allow a multi-character symbol as an alias.
20951 (parse_thong_decl): New function.

20962 Revised and use multiple warnxxx functions to avoid using VARARGS1.
20963 (read_declarations): Improve the error message for
20964 an invalid character. Do not abort.
20965 (read_declarations, copy_guard, copy_action): Use
20966 printable_version to avoid unprintable characters in printed output.
20967 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.

20992 (lex): Use literalchar.
20993 (lex): Implemented "..." tokens.
20994 (literalchar, lex, parse_percent_token): Made tokenbuffer
20995 always contain the token. This includes growing the token
20996 buffer while reading an integer.
20997 (parse_percent_token): Replaced if-else statement with percent_table.
20998 (parse_percent_token): Added % declarations as another
20999 way to specify the flags -n, -l, and -r. Also added hooks for
21000 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
21001 major changes to files.c.
21002 (lex) Retain in the incoming stream a character following
21004 (skip_white_space, lex): Revised most error messages
21005 and changed fatal to warn to avoid aborting.
