740 Fix dependence on computed configure variables.
741 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not
742 $(top_srcdir)/configure.ac so that changes to computed variables, such
743 as PACKAGE_VERSION, are seen.
744 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
746 2008-07-20 Joel E. Denny <jdenny@ces.clemson.edu>

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

806 Fix some .gitignore and .cvsignore problems.
807 * bootstrap (insert_sorted_if_absent): Replace all uses with...
808 (insert_vc_ignore): ... this new function, which prepends `/' to all
809 .gitignore entries before passing them to insert_sorted_if_absent.
810 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that

829 * lib/.gitignore, lib/.cvsignore (/unsetenv.c): Add.
830 * m4/.gitignore, m4/.cvsignore (/environ.m4): Add.
832 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
833 the first argument because it may become position-dependent, and unset
834 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
835 Add comments explaining these issues in more detail.
837 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

895 * THANKS: Add Eric Blake.
897 2008-04-23 Eric Blake <ebb9@byu.net>
899 Revert prior patch, by working around autoconf regression.
900 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
901 ("Output file name: ("): Uncomment test.
902 ("Output file name: )"): Likewise.
903 Based on an idea from Noah Misch.
905 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
907 Work-around an Autoconf 2.62 AT_SETUP bug that was not present in

921 Update to the current gnulib CVS repository, and fix trigraph handling
923 * bootstrap: Update gnulib CVS repository URL.
924 (symlink_to_dir): Encapsulate the code that guarantees the destination
925 directory exists into...
926 (check_dst_dir): ... this new function, and...
927 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
928 fail when copying files into lib/uniwidth/.
929 * src/output.c (prepare_symbols): When writing yytname muscles, where
930 symbol names will be encoded in C-string literals, tell quotearg to
931 escape trigraphs. This used to be the default in gnulib.
932 * tests/regression.at (Token definitions): Because of the change in
933 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
934 escapes trigraphs in symbol names. Thus, yytname no longer has
935 trigraphs unnecessarily doubly escaped. Update test case output.
936 Extend test case to be sure Bison's own error messages will no longer
937 have trigraphs in symbol names unnecessarily escaped once.
939 2008-04-20 Joel E. Denny <jdenny@ces.clemson.edu>

952 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
953 consistency. Update the -g and -x entries now that they take
954 arguments. Use brackets to indicate optional arguments.
955 * src/getargs.c (usage): Explain the relationship between arguments of
956 long and short options more completely. Document --defines and -d
957 separately since the former takes an argument but, for POSIX Yacc, the
959 (short_options): Let -W take an optional argument like --warnings.
960 (getargs): Sort cases.
962 2008-02-28 Akim Demaille <demaille@gostai.com>

974 -g and -x take optional arguments, just like their long options.
975 * build-aux/cross-options.pl: Use /x to make the regexp easier to
977 Fix the handling of $opt which resulted in all the argument to be
978 considered as optional.

1016 * data/yacc.c: Clean up whitespace in the output a little.
1017 (yypstate_allocated): Define for impure push parsers regardless of
1018 whether the pull interface is also requested.
1019 * tests/push.at (Push Parsing: Multiple impure instances): Extend to
1020 check impure push parsers without the pull interface.
1022 * data/yacc.c (yypstate_new): Don't try to invoke yyerror since
1023 yyerror takes arguments specified by %parse-param while yypstate_new

1616 (C++ Bison Interface): Mention `%define namespace' instead of
1618 (Table of Symbols): Remove the `%define push_pull' entry. The %define

1714 parsing requests here...
1715 * data/yacc.c: ... hack this to switch to push.c any time

1717 will go away when we mv push.c yacc.c.
1718 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
1719 push parsing is not supported since unused %define variables are

1928 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
1930 Get rid of broken %no-parser, -n, and --no-parser implementation and
1932 * TODO: Don't mention them.
1933 * doc/bison.1: Likewise.
1934 * doc/bison.texinfo (Decl Summary): Likewise.
1935 (Bison Options): Likewise.
1936 (Option Cross Key): Likewise.
1937 * src/getargs.c (no_parser_flag): Remove global variable.
1938 (usage): Don't print description of -n and --no-parser.
1939 (long_options): Remove --no-parser entry here.
1940 (getargs): Remove -n case in the switch here.
1941 * src/getargs.h (no_parser_flag): Remove extern.
1942 * tests/regression.at (Web2c Actions): Remove comment that mentions
1945 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
1947 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
1948 name user variables starting with `yy'. Just pass NULL instead of a
1949 dummy local &yylval to yypush_parse.
1950 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
1953 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
1955 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
1956 true since it's then always used regardless of whether yyoverflow is
1957 defined. Reported by Christian Burger at
1958 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
1959 * THANKS: Add Christian Burger.
1961 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
1962 node names: say "Decl Summary" not "Bison Declaration Summary".
1964 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
1966 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
1967 determine whether this function has already complained about an invalid
1968 value for a %define boolean variable, don't check whether Bison has
1969 ever examined the value. As written, the check was a tautology.
1970 Instead, record and check for this complaint using a separate muscle.
1972 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
1974 Fix push parsing memory leak reported by Brandon Lucia at
1975 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
1976 * THANKS: Add Brandon Lucia.
1977 * data/push.c (yypstate_delete): Free the stack if it was reallocated
1978 but the parse never completed and thus freed it.
1979 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
1980 * tests/testsuite.at: Include push.at.
1981 * test/push.at: New.
1982 (Push Parsing: Memory Leak for Early Deletion): New test case.
1984 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
1986 Improve handling of multiple S/R conflicts in the same state and of S/R
1987 conflicts involving multiple reductions.
1988 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
1989 set for a state here or Bison will abort if it is reassigned on a
1990 later conflicted reduction in the same state.
1991 Similarly, don't finalize and assign the solved conflicts report here
1992 or it will be lost if it is reassigned on a later conflicted reduction
1994 (set_conflicts): Instead, assign them both here after all S/R conflicts
1995 in the state have been fully examined.
1996 * src/print.c (shift_set): Rename to...
1997 (no_reduce_set): ... this.
1998 (print_reductions): Update for rename, and add %nonassoc error action
1999 tokens to no_reduce_set so that, when printing the first remaining
2000 reduction on an error action token, the reduction is enclosed in
2002 (print_results): Update for rename.
2003 * tests/conflicts.at (Solved conflicts report for multiple reductions
2004 in a state): New test case.
2005 (%nonassoc error actions for multiple reductions in a state): New test
2008 * src/main.c (main): Don't depend on C99 features.
2010 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
2012 * build-aux/.cvsignore: Add compile.
2013 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
2016 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
2018 * bootstrap (slurp): Create target directories that don't exist.
2019 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
2021 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
2023 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
2025 * closure.c (closure): Likewise.
2026 * state.h (reductions): Comment sorting of rules.
2027 (state): Comment sorting of items.
2029 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
2031 Fix C++ test cases after recent Gnulib changes. Discussed starting at
2032 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
2033 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
2034 definition in order to avoid Gnulib headers since we don't use config.h
2036 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
2037 rather than AT_DATA so that config.h is included.
2039 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
2041 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
2042 instead of fprintf. Guard these functions with #if YYDEBUG instead of
2043 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
2044 and so that YYFPRINTF is guaranteed to be defined here.
2046 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
2048 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
2050 (muscle_percent_define_check_values): ... this more helpful function.
2051 Again, it's not used yet, but it will be.
2052 * src/muscle_tab.h: Likewise.
2054 Improve some comments in parser table construction.
2055 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
2056 (generate_states): Don't mention ruleset, which is internal to closure.
2057 * src/closure.c (closure): Explain sorting of core and itemset, which
2058 is required for this function to behave correctly.
2059 * src/closure.h (closure): Mention sorting.
2061 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
2063 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2064 move the check for disabled transitions to an aver since conflict
2065 resolution hasn't happened yet.
2067 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
2068 labels a state as inconsistent just because it has error transitions.
2069 The original form of this check appeared in revision 1.1 of lalr.c,
2070 which was committed on 1991-12-21. Now (at least), changing the
2071 consistency label on such a state appears to have no useful effect in
2072 any of the places it is examined, which I enumerate below. The key
2073 point to understanding each item in this enumeration is that a state
2074 with an error transition is labelled consistent in the first place only
2075 if it has no rules, so the check cannot matter for states that have
2076 rules. (1) Labelling a state as inconsistent will cause set_conflicts
2077 to try to identify its conflicts, and a state must have *rules* to have
2078 conflicts. (2) Labelling a state as inconsistent will affect how
2079 action_row sets the default *rule* for the state. (3) Labelling a
2080 state as inconsistent will cause build_relations to add lookback edges
2081 to *rules* in that state.
2082 * src/state.h (struct state): Word the comment for member consistent
2085 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
2087 Don't depend on C99 features.
2088 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
2089 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
2090 * src/reader.c (check_and_convert_grammar): Fix for-loop.
2091 * src/state.c (state_mark_reachable_states): Fix for-loop.
2092 (state_remove_unreachable_states): Fix for-loop.
2094 Don't widen struct state with member reachable just to temporarily
2095 record reachability. Instead, use a local bitset.
2096 * src/state.h (struct state): Remove member.
2097 * src/state.c (state_new): Don't initialize it.
2098 (state_mark_reachable_states): Rename to...
2099 (state_record_reachable_states): ... this, and use bitset.
2100 (state_remove_unreachable_states): Use bitset.
2102 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
2104 * src/Makefile.am (yacc): Quote target action commands properly so
2105 that the yacc script isn't corrupt. Reported by Hans Aberg at
2106 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
2108 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
2109 the case of pure parsers. Reported by Frans Englich at
2110 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
2111 * THANKS: Add Frans Englich.
2113 * NEWS (2.3a+): In the %code entry, reference section `Bison
2114 Declaration Summary' from the manual now since the %code summary has
2116 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
2117 in the rules section must be terminated by semicolons.
2119 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
2121 Extend the front-end API for %define variables to more completely
2122 mirror the back-end. This will be useful in the future.
2123 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
2124 Update comments to mention the new front-end counterparts of these
2126 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code

2136 * src/muscle_tab.h (muscle_percent_define_get,
2137 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
2140 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
2142 * NEWS (2.3a+): Mention yesterday's state-removal change.
2143 (2.3a): Remove the %language entry, which was added after 2.3a.
2144 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
2145 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
2146 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
2147 tests/existing.at: Update copyright date.
2149 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
2151 If conflict resolution makes states unreachable, remove those states,
2152 report rules that are then unused, and don't report conflicts in those

2174 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
2175 (new_itemsets, save_reductions): Update for rename to nitemset.
2176 * src/closure.c (nritemset): Rename to...
2177 (nitemset): ... this since the "r" appears to meaningless and isn't
2178 used in the comments.
2179 (closure): Update for rename.
2180 * src/closure.h (nritemset): Update extern to...
2181 (nitemset): ... this.

2300 * tests/input.at (%define errors): Update expected output.
2301 * tests/skeletons.at (%define boolean variables: invalid skeleton

2306 * src/print.c (lookahead_set, state_default_rule): Remove.
2307 (print_reductions): Replace state_default_rule invocation with
2308 equivalent use of yydefact, which was computed in token_actions in
2310 (print_results): Don't allocate lookahead_set.
2312 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
2314 * data/lalr1.java: Prefix all private members with yy.
2316 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
2318 Use YYFPRINTF instead of fprintf where appropriate. Reported by
2319 Sebastien Fricker at
2320 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
2321 * THANKS: Add Sebastien Fricker.

2336 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
2338 Undo my 2007-02-07 change, switching back to the c-strcase module
2339 introduced in the 2007-02-03 change. Bruno Haible reported that
2340 the 2007-02-07 change would be dangerous in Turkish if we add a
2341 language whose name contains "i", since "i" is not lowercase "I"
2343 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
2344 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,

2364 * src/reader.c (packgram): Move translation of rule actions from the
2365 beginning of packgram to...
2366 (check_and_convert_grammar): ... here right before packgram is invoked
2367 so it's easier to write more complete comments, and remove redundant
2370 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
2372 As in semantic actions, make @$ in %initial-action, %destructor, and
2373 %printer imply %locations.
2374 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
2376 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
2377 (@$ in %initial-action implies %locations,
2378 @$ in %destructor implies %locations,
2379 @$ in %printer implies %locations): ... these new test cases.
2381 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
2383 Undo most of the 2007-02-03 change, switching to the strcase module
2384 now that gnulib strcase has been fixed.
2385 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
2386 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
2387 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
2388 * m4/.cvsignore: Add strcase.m4.
2389 * src/getargs.c: Revert 2007-02-03 change, as follows.
2390 Don't include c-strcase.h.
2391 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
2392 strcasecmp has "unspecified behavior" outside the POSIX locale,
2393 but it works fine in practice if at least one argument is ASCII,
2394 as is the case in Bison.
2396 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
2398 * tests/java.at: Skip tests if only one of javac/java is present.
2399 Reported by Joel E. Denny.
2400 * tests/atlocal.in: Adjust copyright years.
2402 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
2404 * data/lalr1.java (Stack): Work around old verifiers that disallow
2405 access to the private fields of an inner class, from the outer class.
2406 We can make Stack's fields public because user code doesn't have access
2407 to the instance of Stack used by parse(). Reported by Paul Eggert.
2409 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
2411 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
2412 the right spot for these files?
2413 * bootstrap.conf (gnulib_modules): Add c-strcase.
2414 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
2416 * src/getargs.c: Include c-strcase.h.
2417 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
2418 to avoid unspecified behavior.
2420 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
2422 * doc/bison.texinfo (Decl Summary): Correct typo.
2424 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
2426 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
2427 Complain if the value does not match empty, "true" or "false".
2428 * data/c++.m4: Adjust default definitions of %define variables.
2429 * data/java.m4: Adjust default definitions of %define variables.
2430 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
2432 * tests/input.at (Boolean %define variables): Test new behavior.
2434 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
2436 * NEWS: Mention java.
2437 * TODO: Remove things that are done.
2438 * bootstrap.conf: Add javacomp-script and javaexec-script.
2439 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
2441 * data/Makefile.am: Add new files.
2442 * data/java-skel.m4: New.
2443 * data/java.m4: New.
2444 * data/lalr1.java: New.
2446 * doc/bison.texinfo: Put "A Complete C++ Example" under
2447 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
2448 under Other Languages.
2450 * src/getargs.c (valid_languages): Add Java.
2451 * src/getargs.h (struct bison_language): Update size of string fields.
2453 * tests/Makefile.am: Add java.at.
2454 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
2455 * tests/java.at: New.
2456 * tests/testsuite.at: Include it.
2458 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
2461 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
2462 at_directive_argv arguments so these no longer have to be global
2463 variables. Also, update the implementation for the following changes.
2464 (fail_for_at_directive_too_many_args,
2465 fail_for_at_directive_too_few_args): Add at_directive_name argument.
2466 (at_directive_name): Remove as at_directive_argv[0] will be used for
2468 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
2469 for the directive name.
2470 (at_directive_argc, at_directive_argv): Make these local within
2471 skel_lex instead of global.
2472 (INITIAL): Update directive start action for above changes.
2473 (SC_AT_DIRECTIVE_ARG): Rename to...
2474 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
2475 (SC_AT_DIRECTIVE_SKIP_WS): Update.
2476 (scan_skel): Move yylex_destroy to...
2477 (skel_scanner_free): ... here.
2478 * tests/skeletons.at (installed skeleton file name): Rename to...
2479 (installed skeleton file names): ... this.
2481 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
2483 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
2484 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
2485 Summary" not "Directives".
2486 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
2487 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
2488 since the former is now the more complete one.
2489 (Prologue Alternatives): Likewise and do the same for %defines.
2490 (Table of Symbols): Add summary of %code, add summary of %define, and
2491 move full %code documentation to...
2492 (Decl Summary): ... here for consistency with other entries in these
2494 Move %define entry in order to keep this list alphabetized.
2495 Reword %define entry a little to put less emphasis on the skeleton
2496 concept, which most users shouldn't have to think about.
2498 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
2500 Adjust to recent gnulib changes.
2501 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
2502 Add string.h, string_.h, unistd_.h, wchar_.h.
2503 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
2504 * src/system.h: Don't include <stpcpy.h>; this is now done by
2507 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
2509 Simplify implementation of unqualified %code, implement macros for
2510 uniform treatment of boolean %define flags. Document %define.
2511 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
2512 b4_percent_code_ifdef): New.
2513 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
2514 * data/c++.m4: Define default value for global_tokens_and_yystype.
2515 * data/glr.cc: Likewise.
2516 * data/location.cc: Use b4_percent_define_flag_if.
2518 * doc/bison.texinfo (Decl Summary): Document %define.
2520 * src/parse-gram.y (Unqualified %code): Change muscle name to
2522 (content.opt): Default to empty.
2524 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
2526 Implement support for relative and absolute skeleton file names.
2527 Discussed starting at
2528 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
2529 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
2530 (Bison Options): Document in --skeleton entry.
2531 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
2532 full_skeleton can't necessarily hold all of pkgdatadir.
2533 If the specified skeleton file name contains a `/', don't prepend
2535 * src/parse-gram.y (prologue_declaration): If the specified skeleton
2536 file name contains a `/', prepend the grammar file directory.
2537 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
2538 * skeletons.at: New file.
2539 (relative skeleton file names): New test case.
2540 (installed skeleton file names): New test case.
2541 * tests/testsuite.at: Include skeletons.at.
2543 * bootstrap: Update copyright to 2007.
2545 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
2547 * bootstrap: Remove occurrences of .#bootmp from the files.
2549 2007-01-17 Akim Demaille <akim@epita.fr>
2551 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
2553 Use per-type %printer.
2555 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
2557 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

2565 2007-01-16 Akim Demaille <akim@epita.fr>
2567 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
2569 (Calc++ Scanner): Exit with failure if we can't open the input
2571 Accept "-" standing for stdin.
2572 (Calc++ Top Level): Print the result only if the parsing was
2575 2007-01-16 Akim Demaille <akim@epita.fr>
2577 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
2579 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
2580 and Joel E. Denny <jdenny@ces.clemson.edu>
2582 Clean up %define and %code implementation in M4 some. Most
2583 importantly, rename all related macros to be in the b4_percent_define
2584 and b4_percent_code namespaces. Also, complete support for `.' in
2585 %define variable names and %code qualifiers.
2586 * data/bison.m4 (b4_check_user_names): Check for special
2587 "SKELETON-NAMESPACE(name)" macros instead of using two nested
2589 (b4_get_percent_define, b4_get_percent_code): Rename to...
2590 (b4_percent_define_get, b4_percent_code_get): ... these.
2591 Extend documentation with examples.
2592 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
2593 b4_percent_define_skeleton_variables and
2594 b4_percent_code_skeleton_qualifiers.
2595 Expect any value for the %define variable `foo' to be stored in the
2596 macro named `b4_percent_define(foo)'; expect any %code blocks for the
2597 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
2598 expect any unqualified %code blocks to be stored in a macro named
2599 `b4_percent_code_unqualified'.
2600 Use m4_indir so that %define variable names and %code qualifiers can
2601 contain `.', which is allowed by the grammar parser.
2602 (b4_percent_define_default): New macro to set a default value for a
2604 (m4_wrap): Update wrapped code, and fix some underquoting.
2605 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
2606 Expect grammar uses of %define variables and %code qualifiers to be
2607 defined in b4_percent_define_user_variables and
2608 b4_percent_code_user_qualifiers.
2609 * data/c++.m4: Use b4_percent_define_default rather than
2610 m4_define_default. Fix some underquoting. Skeleton usage of %define
2611 variable define_location_comparison now implies skeleton usage of
2612 %define variable filename_type.
2613 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
2614 data/push.c, data/yacc.c: Update macro names.
2615 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
2618 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
2620 DJGPP specific issues.
2622 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
2623 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
2625 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2627 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
2628 run parsers in all tests so that Valgrind is invoked during
2629 maintainer-check-valgrind.
2630 (Duplicate representation of merged trees): Free all semantic values.
2631 (Duplicated user destructor for lookahead): Likewise.
2633 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2635 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
2636 command-line prefix.
2637 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
2638 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
2639 miss Valgrind messages.
2640 (Exploding the Stack Size with Malloc): Likewise.
2642 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2644 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
2645 locals. Reported by Juan Manuel Guerrero at
2646 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
2647 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
2648 Fix some indentation also.
2649 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
2650 explaining this issue.
2652 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
2653 and Joel E. Denny <jdenny@ces.clemson.edu>
2655 Simplify union and prologue handling, and escape union and lex/parse
2656 params with digraphs.
2657 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
2658 values to the empty string since these are no longer guaranteed
2659 initialized by the front-end.
2660 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
2661 braces around b4_user_stype since this is no longer done by the
2663 * src/files.c, src/files.h (pre_prologue_obstack,
2664 post_prologue_obstack): Remove.
2665 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
2666 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
2667 with digraphs. This fixes lex params and parse params.
2668 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
2669 * src/output.c (prepare): Remove muscle insertion of the prologues.
2670 (output): Remove freeing of pre_prologue_obstack and
2671 post_prologue_obstack.
2672 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
2673 than prologue_augment for prologue parsing so you don't need prologue
2675 (grammar_declaration): For %union RHS, use `braceless' instead of
2676 "{...}" so that braces are already stripped and code is escaped with
2678 * src/reader.c (prologue_augment): Remove.
2679 (reader): Remove initialization of pre_prologue_obstack and
2680 post_prologue_obstack.
2681 * src/reader.h (prologue_augment): Remove.
2683 * data/c.m4: Remove stray parenthesis.
2685 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2687 Remove quotes from variables names in %define directives and from
2688 qualifiers in %code directives, and restrict the characters that are
2689 allowed in them to M4-friendly ones. For %define, continue to support
2690 the quoted form as a deprecated feature. Discussed starting at
2691 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
2692 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
2694 * doc/bison.texinfo (Prologue Alternatives): Update.
2695 (Decl Summary): In %defines entry, update mention of `%code requires'
2696 and `%code provides'.
2697 (C++ Location Values): Update %define uses.
2698 (Calc++ Parser Interface): Likewise.
2699 (Calc++ Parser): Likewise, and update `%code requires' uses.
2700 (Table of Symbols): Update %code documentation.
2701 * src/parse-gram.y (prologue_declaration): For %define variables, use
2702 `variable' instead of `STRING'.
2703 (grammar_declaration): For %code qualifiers, use `ID' instead of
2705 (variable): New nonterminal that takes an `ID' or a `STRING'.
2706 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
2708 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
2709 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
2710 (%define errors): Update %define uses.
2712 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2714 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
2715 instead of muscle_insert for %define values so that M4-special
2716 characters are replaced with digraphs.
2717 * tests/input.at (%define errors): Extend to check weird values.
2719 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2721 Instead of having skeletons declare all valid %define variables and
2722 %code qualifiers, provide macros that retrieve the associated values
2723 and build these lists automatically. Thus Bison will now warn when a
2724 variable or qualifier is not used by the skeleton in the current
2725 invocation regardless of whether it might sometimes be used by that
2726 skeleton in other invocations. Also, move all %define value macros to
2727 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
2728 form, which is replaced by %code.
2729 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
2730 (b4_check_user_names): ... this, and change the series of valid name
2731 arguments to a single list argument for names used in the skeleton
2732 similar to the existing list argument for names used in the grammar.
2733 Warn instead of complaining.
2734 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
2735 values and %code code, to format %code code properly, and to build
2736 lists of all %define variables and %code qualifiers used in the
2737 skeleton: b4_skeleton_percent_define_variables and
2738 b4_skeleton_percent_code_qualifiers.
2739 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
2741 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
2742 the skeleton names lists can finish building first. In place of
2743 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
2744 expect the lists b4_user_percent_define_variables and
2745 b4_user_percent_code_qualifiers.
2746 * data/c++.m4: Where setting default values for b4_parser_class_name,
2747 b4_location_type, b4_filename_type, b4_namespace, and
2748 b4_define_location_comparison, update their names to the
2749 b4_percent_define_ namespace.
2750 * data/glr.c: Don't use b4_check_percent_define_variables and
2751 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2752 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
2753 (b4_parser_class_name, b4_namespace): Define these using
2754 b4_get_percent_define for parser_class_name and namespace.
2755 * data/location.cc: Use b4_get_percent_define.
2756 * data/push.c: Don't use b4_check_percent_define_variables and
2757 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2758 * data/yacc.c: Likewise, and don't call m4_exit in
2759 b4_use_push_for_pull_if or m4_wrap code will never execute.
2760 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
2762 (muscle_grow_user_name_list): ... this for consistency with the
2763 terminology used in bison.m4.
2764 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
2765 %define variable names, and rename muscle used_percent_define_variables
2766 to user_percent_define_variables.
2767 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
2768 user_percent_code_qualifiers.
2770 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
2771 {CODE} form is no longer accepted.
2772 * tests/input.at (Reject bad %code qualifiers): Rename to...
2773 (Reject unused %code qualifiers): ... this, and update test output.
2774 (%define error): Update test output.
2776 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
2778 Check for unrecognized %define variables similar to checking for
2779 unrecognized %code qualifiers. Check for redefined %define variables.
2780 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
2782 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
2783 (b4_check_percent_define_variables): New, also wraps it.
2784 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
2785 variables using b4_check_percent_define_variables.
2786 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
2787 all those exercised in the test suite and all those listed in the
2788 `Default values' section of c++.m4. Are there others?
2789 * data/push.c, data/yacc.c: Declare no valid %define variables.
2790 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
2791 similar to muscle_find, but it works even when the muscle stores a
2793 (muscle_grow_used_name_list): New function for constructing the used
2794 name list muscles that b4_check_for_unrecognized_names requires.
2795 * src/parse-gram.y (prologue_declaration): Warn if a variable is
2796 %define'd more than once. Define the b4_used_percent_define_variables
2797 muscle with muscle_grow_used_name_list.
2798 (grammar_declaration): Abbreviate %code code with
2799 muscle_grow_used_name_list.
2800 * tests/input.at (%define errors): New.
2802 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2804 Provide warn_at, complain_at, and fatal_at function callbacks to the
2805 skeletons, and use this for %code qualifier complaints.
2806 * data/bison.m4 (b4_error_at): New, invoked by...
2807 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
2808 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
2809 @fatal_at(...@) directives.
2810 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
2811 qualifiers in b4_used_percent_code_qualifiers and to use
2813 * src/location.c, src/location.h (boundary_set_from_string): New global
2815 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
2817 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
2818 to b4_used_percent_code_qualifiers.
2819 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
2821 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
2822 (lineno): Rename to...
2823 (out_lineno): ... this so I don't misunderstand it again.
2824 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
2825 here; these newlines are in the input but not the output file.
2826 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
2827 (at_directive_perform): ... this new static function, and add handling
2828 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
2830 * tests/input.at (Reject bad %code qualifiers): Update test output with
2831 locations and extend.
2833 * tests/output.at (Output file name: [, Output file name: ]): Remove
2834 bogus comment about these tests failing.
2836 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2838 Clean up b4_check_percent_code_qualifiers a little.
2839 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
2840 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
2841 documentation and add examples.
2842 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
2845 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
2847 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
2848 unreliable -- especially when they're hidden inside another macro.
2849 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
2850 data/c.m4: Remove m4_divert(-1).
2851 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
2852 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
2853 m4_divert_push(0) and m4_divert_pop(0).
2854 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
2855 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
2856 pushed and popped by m4sugar, should be first on the stack.
2858 Provide warn, complain, and fatal function callbacks to the skeletons.
2859 This provides more flexibility than m4_fatal, improves the error
2860 message format, and captures messages for translation. Discussed
2862 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
2863 * data/bison.m4 (b4_error): New, invoked by...
2864 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
2865 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
2866 directives. Because these M4 macros might be called when the current
2867 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
2868 the previous removal of uses of m4_divert, which caused trouble.
2869 (b4_check_percent_code_qualifiers): Use b4_complain instead of
2870 m4_fatal to report unrecognized %code qualifiers.
2871 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
2872 push parser requests.
2873 * data/glr.c: Use b4_complain instead of m4_fatal to report
2874 non-deterministic push parser requests.
2875 Update @output usage to @output(...@) form.
2876 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
2877 report missing %defines. Update @output usage to @output(...@) form.
2878 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
2880 * src/main.c (main): Invoke skel_scanner_free.
2881 * src/scan-skel.h (skel_scanner_free): Prototype new function.
2882 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
2883 obstack_for_string from flex-scanner.h.
2884 (YY_DECL): Use to declare skel_lex static.
2885 (decode_at_digraphs): Remove; now handled in the new
2886 SC_AT_DIRECTIVE_ARG start condition.
2887 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
2889 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
2890 at_directive_argv): New static globals.
2891 (INITIAL): Use fail_for_invalid_at.
2892 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
2893 recognize the start of a generalized `@directive(...@)' form and
2895 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
2896 directive args (using the new obstack_for_string), to decode the
2897 contained @ diagraphs, and to perform the directive. It recognizes
2898 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
2900 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
2901 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
2903 (scan_skel): Initialize obstack_for_string on the first call.
2904 (skel_scanner_free): New function to free obstack_for_string.
2905 * tests/input.at (Reject bad %code qualifiers): Update test output.
2907 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
2909 Consolidate the 4 prologue alternative directives (%code, %requires,
2910 %provides, and %code-top) into a single %code directive with an
2911 optional qualifier field. Discussed at
2912 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
2913 * NEWS (2.3a+): Rewrite the existing entry for the prologue
2915 * doc/bison.texinfo (Prologue Alternatives): Update.
2916 (Decl Summary): Update to %code "requires" and %code "provides".
2917 (Calc++ Parser): Update to %code "requires".
2918 (Table of Symbols): Remove entries for %requires, %provides, and
2919 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
2920 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
2921 are replaced by b4_percent_code_provides and b4_percent_code_requires,
2922 which are skeleton-specific.
2923 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
2924 declare what %code qualifiers it supports and to complain if any other
2925 qualifiers were used in the grammar.
2926 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
2927 and b4_user_code([b4_percent_code_provides]) in place of
2928 b4_user_requires and b4_user_provides.
2929 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
2930 Add b4_user_code([b4_percent_code_top]) and
2931 b4_user_code([b4_percent_code]).
2932 Invoke b4_check_percent_code_qualifiers.
2933 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2934 PERCENT_REQUIRES): Remove.
2935 (grammar_declaration): Remove RHS's for %code-top, %provides, and
2936 %requires. Rewrite the %code RHS as the unqualified form defining the
2937 muscle b4_percent_code. Add another RHS for the qualified %code form,
2938 which defines muscles of the form b4_percent_code_QUALIFIER and the
2939 b4_used_percent_code_qualifiers muscle.
2940 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2941 PERCENT_REQUIRES): Remove.
2942 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
2943 %code "requires" and %code "provides".
2944 * tests/input.at (Reject bad %code qualifiers): New.
2946 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2948 Use the new code_props interface for destructors and printers.
2949 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
2950 printer_location members, and change the type of the destructor and
2951 printer members to code_props.
2952 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
2953 symbol_printer_get, semantic_type_destructor_set,
2954 semantic_type_printer_set, default_tagged_destructor_set,
2955 default_tagless_destructor_set, default_tagged_printer_set,
2956 default_tagless_printer_set): Use code_props in arguments and return
2957 types in place of char const * and location.
2958 (symbol_destructor_location_get, symbol_printer_location_get): Remove
2959 since the locations are now contained in the return of
2960 symbol_destructor_get and symbol_printer_get.
2961 * src/output.c (symbol_destructors_output, symbol_printers_output):
2963 (symbol_code_props_output): ... this to eliminate duplicate code.
2964 (output_skeleton): Update to use symbol_code_props_output.
2965 * src/reader.c (symbol_should_be_used): Update use of
2966 symbol_destructor_get.
2967 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
2968 Update uses of the various _destructor_set and _printer_set functions.
2969 * src/symtab.c: (default_tagged_destructor_location,
2970 default_tagless_destructor_location, default_tagged_printer_location,
2971 default_tagless_printer_location): Remove since we...
2972 (default_tagged_destructor, default_tagless_destructor,
2973 default_tagged_printer, default_tagless_printer): ... change the type
2974 of these to code_props.
2975 (symbol_new, semantic_type_new, symbol_destructor_set,
2976 semantic_type_destructor_set, symbol_destructor_get,
2977 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
2978 symbol_check_alias_consistency, default_tagged_destructor_set,
2979 default_tagless_destructor_set, default_tagged_printer_set,
2980 default_tagless_printer_set): Update.
2981 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
2982 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
2984 (symbol_print): Use SYMBOL_CODE_PRINT.
2986 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2988 Use the new code_props interface for rule actions.
2989 * src/symlist.h (symbol_list): Replace action, action_location, and
2990 used members with a code_props action_props member.
2991 * src/reader.c (symbol_should_be_used, grammar_rule_check,
2992 grammar_midrule_action, grammar_current_rule_merge_set,
2993 grammar_current_rule_symbol_append, packgram): Update.
2994 * src/scan-code.h (translate_rule_action): Remove, no longer used.
2995 * src/scan-code.l (handle_action_dollar): Update.
2996 (translate_rule_action): Remove, no longer used.
2997 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
2999 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3001 Use the new code_props interface in parse-gram.y.
3002 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
3003 Update all uses of translate_* functions to use the new code_props
3004 interface and to use gram_scanner_last_string_free and
3005 code_scanner_last_string_free where possible.
3006 (grammar_declaration): symbol_list_destructor_set and
3007 symbol_list_printer_set now perform the translation, so don't do it
3008 here. Use gram_scanner_last_string_free where possible.
3009 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
3010 translate_code): Remove, no longer used.
3011 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
3012 symbol_list_printer_set): Perform code translation here rather than
3013 depending on the caller to do so.
3015 * src/symlist.h (struct symbol_list): Correct some documentation typos.
3016 * src/scan-gram.h (gram_last_string): Remove declaration.
3017 * src/scan-gram.l (last_string): Declare it static.
3019 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3021 Encapsulate code properties and related functionality for the various
3022 destructors, printers, and actions into a code_props structure and
3023 interface. This patch merely implements code_props in scan-code.h and
3024 scan-code.l. Future patches will rewrite other modules to use it.
3025 Discussed starting at
3026 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
3027 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
3028 consistently initialize const structs that have an empty location
3030 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
3031 to ensure consistency.
3032 * src/scan-code.h (code_props): New structure.
3033 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
3034 function, macro, and const global variable for initializing a
3035 code_props with no code.
3036 (code_props_plain_init, code_props_symbol_action_init,
3037 code_props_rule_action_init, code_props_translate_code): The rest of
3038 the new code_props functional interface. Among other things, the init
3039 functions set the code_props kind field so that
3040 code_props_translate_code will know whether to behave like
3041 translate_symbol_action, translate_rule_action, or translate_code.
3042 These old translate functions must remain until all other modules are
3043 updated to use the new code_props interface.
3044 (code_scanner_last_string_free): New function similar to
3045 gram_scanner_last_string_free.
3046 (code_scanner_free): Add documentation.
3047 * src/scan-code.l: Implement the new interface.
3048 (code_lex): Make it static, add a code_props* argument, and remove the
3050 (last_string): New static global similar to the one in scan-gram.l.
3051 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
3053 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
3054 code_props since Bison may one day use this information for destructors
3056 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
3057 (handle_action_dollar): Use symbol_list_n_get and set used flag
3058 directly since symbol_list_n_used_set is removed.
3059 (translate_action): Add a code_props* argument and remove the rule,
3060 action, and location arguments. Pass the code_props* on to code_lex.
3061 (translate_rule_action, translate_symbol_action, translate_code):
3062 Rewrite as wrappers around the new code_props interface.
3063 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
3064 it would eventually need to break the encapsulation of code_props.
3066 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3068 * etc/.cvsignore: New.
3070 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3072 Add maintainer-push-check to run maintainer-check using push parsing in
3073 place of pull parsing where available.
3074 * Makefile.am (maintainer-push-check): New.
3075 * data/bison.m4 (b4_use_push_for_pull_if): New.
3076 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
3077 appropriately based on their existing values.
3078 (yypush_parse): Don't print push-parser-specific diagnostics if push
3079 parsing is being used in place of pull parsing.
3080 * data/yacc.c: If push parsing should replace pull parsing, redirect to
3082 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
3083 variable, and insert b4_use_push_for_pull_flag into muscles.
3084 * tests/Makefile.am (maintainer-push-check): New.
3086 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3088 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
3089 (whether successful or failed) so that yypush_parse can be invoked
3090 again to start a new parse using the same yypstate.
3091 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
3092 check multiple yypull_parse invocations on the same yypstate. For pull
3093 mode, extend to check multiple yyparse invocations.
3094 (Exploding the Stack Size with Alloca): Extend to try with
3096 (Exploding the Stack Size with Malloc): Likewise.
3098 * tests/calc.at (Simple LALR Calculator): Don't specify
3099 %skeleton "push.c" since %push-pull-parser implies that now.
3100 * tests/headers.at (export YYLTYPE): Don't check for the push
3101 declarations. Otherwise, this test case can't be used to see if push
3102 mode can truly emulate pull mode.
3103 * tests/input.at (Torturing the Scanner): Likewise.
3104 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
3105 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
3106 AT_YACC_IF, which now includes the case of push mode since %skeleton
3107 need not be used for push mode. This will be more intuitive once
3108 push.c is renamed to yacc.c.
3110 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3112 For push mode, convert yyparse from a macro to a function, invoke yylex
3113 instead of passing a yylexp argument to yypull_parse, and don't
3114 generate yypull_parse or yyparse unless %push-pull-parser is declared.
3115 Discussed starting at
3116 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
3117 * data/bison.m4 (b4_pull_if): New.
3118 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
3119 * data/push.c: Improve M4 quoting a little.
3120 (b4_generate_macro_args, b4_parenthesize): Remove.
3121 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
3122 any time a pull parser is requested.
3123 Don't #define this as a wrapper around yypull_parse. Instead, when
3124 both push and pull are requested, make it a function that does that
3126 (yypull_parse): If there's a b4_prefix, #define this to
3127 b4_prefix[pull_parse] when both push and pull are requested.
3128 Don't define this as a function unless both push and pull are
3130 Remove the yylexp argument and hard-code yylex invocation instead.
3131 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
3133 * src/getargs.c (pull_parser): New global initialized to true.
3134 * getargs.h (pull_parser): extern it.
3135 * src/output.c (prepare): Insert pull_flag muscle.
3136 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
3137 (prologue_declaration): Set both push_parser and pull_parser = true for
3138 %push-pull-parser. Set push_parser = true and pull_parser = false for
3140 * src/scan-gram.l: Don't accept %push_parser as an alternative to
3141 %push-parser since there's no backward-compatibility concern here.
3142 Scan %push-pull-parser.
3143 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
3144 instead of %push-parser.
3145 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
3146 prototype it in the module that calls yyparse.
3147 * tests/input.at (Torturing the Scanner): Likewise.
3148 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
3150 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
3152 Update etc/bench.pl. Optimize push mode a little (the yyn change
3153 deserves most of the credit).
3154 * Makefile.am (SUBDIRS): Add etc subdirectory.
3155 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
3156 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
3157 yytoken, yyval, and yyloc declarations to...
3158 (yyparse or yypush_parse): ... here to improve performance. For
3159 yypush_parse invocations after the first, be sure to assign yyn its old
3161 (yypstate_new): Don't bother initializing the yyresult field since the
3162 initial value isn't used.
3163 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
3164 remove the #define that, in push mode, set it to yyps->NAME.
3165 * etc/Makefile.am: New.
3166 * etc/bench.pl: Remove and build it instead from...
3167 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
3168 "tests/bison" from the build directory by default rather than just
3169 invoking "bison" from $PATH.
3170 (calc_grammar): Update push parser code: don't declare yylval globally,
3171 don't define yyparse_wrapper, and don't #define yyparse.
3172 (bench_grammar): Update to check all working combinations of yacc.c,
3173 push.c, impure, pure, pull, and push.
3175 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3177 For push mode, add pull wrappers around yypush_parse.
3178 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
3179 (yypull_parse): New function wrapping yypush_parse.
3180 (yyparse): New #define wrapping yypull_parse.
3181 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
3183 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
3184 prototype yylex in the module that calls yyparse, and don't prototype
3185 yyparse there. Otherwise, the yyparse expansion won't compile.
3186 * tests/input.at (Torturing the Scanner): Likewise.
3188 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3190 Enable push parsers to operate in impure mode. Thus, %push-parser no
3191 longer implies %pure-parser. The point of this change is to move
3192 towards being able to test the push parser code by running the entire
3193 test suite as if %push-parser had been declared.
3194 * data/push.c (yypush_parse): For impure mode, remove the
3195 yypushed_char, yypushed_val, and yypushed_loc arguments.
3196 Instead, declare these as local variables initialized to the global
3197 yychar, yylval, and yylloc.
3198 For the first yypush_parse invocation only, restore the initial values
3199 of these global variables when it's time to read a token since they
3200 have been overwritten.
3201 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
3203 * tests/calc.at (Simple LALR(1) Calculator): Always declare
3204 %pure-parser along with %push-parser since this test case was designed
3205 for pure push parsers.
3206 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
3207 (AT_YACC_OR_PUSH_IF): New.
3208 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
3209 add a note that it's still wrong for some cases (as it has been for a
3211 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
3212 %push-parser no longer implies %pure-parser.
3214 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3216 Remove some unnecessary differences between the pull parser code and
3217 the push parser code. This patch enables yynerrs in push mode.
3218 * data/push.c: Reformat M4 a little.
3219 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
3220 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
3221 because push mode is on. Instead, if pure mode is on, move yynerrs
3223 (b4_declare_parser_state_variables): ... here.
3224 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
3225 to yyps->NAME so it can be used in yypush_parse.
3226 (yypush_parse): Don't omit uses of yynerrs in push mode.
3228 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3230 Fix bug such that the first pushed token's value and location are
3231 sometimes overwritten (sometimes by %initial-action) before being used.
3232 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
3233 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
3234 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
3235 more closely mimic the pull parser logic.
3236 Don't copy the pushed token to yychar, yylval, and yylloc until it's
3237 time to read a token, which is after any initialization of yylval and
3239 (gottoken): Rename label to...
3240 (yyread_pushed_token): ... for clarity and to avoid infringing on the
3243 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3245 Rearrange initialization of the parser state variables so that the
3246 skeleton doesn't have to have a copy for pull mode and another for push
3247 mode. This patch also fixes at least a bug such that yylloc was not
3248 initialized (with b4_location_initial_line and
3249 b4_location_initial_column) upon calling yypush_parse. However, that
3250 initialization now overwrites the first token's location;
3251 %initial-action assigning @$ already did the same thing, and both bugs
3252 will be fixed in a later patch.
3253 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
3254 (b4_declare_parser_state_variables): Remove initialization of yytoken,
3255 yyss, yyvs, yyls, and yystacksize.
3256 (yypstate_new): Remove initialization of some yypstate fields: yystate,
3257 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
3259 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
3260 yyps->NAME so it can be used in yypush_parse.
3261 (yyparse or yypush_parse): For yypush_parse, don't print the
3262 "Starting parse" diagnostic for invocations after the first.
3263 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
3264 yypush_parse, only do it for the first invocation.
3265 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
3266 initialization to occur in yypush_parse but only on the first
3269 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3271 * data/push.c: Add CPP guards around push parser declarations in both
3272 the header and the code file.
3273 In the code file, move the push parser declarations to the same place
3274 they appear in the header file.
3275 Clean up the M4 some, especially the inconsistent underquoting in
3276 some b4_c_function_def and b4_c_function_decl uses.
3278 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3280 Encapsulate the push parser state variables into an M4 macro so the
3281 push skeleton doesn't have to list them again for pull mode's yyparse.
3282 For push mode, remove yypush_parse's local equivalents of these
3283 variables to eliminate unnecessary copying between the two sets at
3284 run-time. This patch also fixes at least a bug related to multiple
3285 %initial-action invocations in push mode.
3286 * data/push.c (b4_declare_parser_variables): Rename to...
3287 (b4_declare_scanner_communication_variables): ... this for clarity and
3289 (b4_declare_yyparse_variables): Remove and move its contents to the one
3290 spot where it was invoked.
3291 (b4_declare_parser_state_variables): New macro containing the parser
3292 state variables required by push mode.
3293 (struct yypstate): Replace all fields but yynew with
3294 b4_declare_parser_state_variables.
3295 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
3296 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
3297 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
3298 (yyparse or yypush_parse): For yyparse in pull mode, replace local
3299 parser state variable declarations with
3300 b4_declare_parser_state_variables.
3301 Don't initialize parser state variables when calling yypush_parse since
3302 yypstate_new already does that.
3303 Invoke the user's initial action only upon the first yypush_parse
3305 Remove all code that copies between the local parser state variables
3308 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3310 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
3311 prevent a name collision in a future patch where these names will
3312 sometimes be #define'd.
3313 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
3314 since it no longer has the same name as the existing argument.
3315 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
3317 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
3318 and Joel E. Denny <jdenny@ces.clemson.edu>
3320 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
3321 that the argument is case-insensitive, and there's no `=' here.
3322 For the %skeleton entry, mention that %language is better.
3323 (Bison Options): Likewise for --language and --skeleton. Move the
3324 --skeleton entry so that the `Tuning the parser' section is sorted
3325 alphabetically on long options.
3326 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
3327 %language directive in detail here; cross-reference the %language
3328 documentation instead.
3329 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
3330 `%require "2.3b"' so that the example is always up-to-date.
3331 (Table of Symbols): Add entries for %language and %skeleton.
3332 * examples/extexi (normalize): Instead of replacing every %require
3333 argument with the current Bison version, just substitute for
3334 `@value{VERSION}'. This guarantees that we're testing what actually
3335 appears in the documentation.
3336 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
3337 rather than `@VERSION@'.
3339 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3341 * NEWS: Reword the %language news a bit, and put it earlier.
3343 * src/getargs.c (skeleton_arg): Last arg is now location const *.
3344 Rewrite to simplify the logic.
3345 (language_argmatch): Likewise.
3346 (program_name): We now own this var.
3347 * src/getargs.h (struct bison_language): Use char[] rather than
3350 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
3352 * src/complain.c (program_name): Remove decl; no longer needed.
3353 * src/main.c (program_name): Remove; now belongs to getargs.
3355 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
3357 * NEWS: Document %language.
3359 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
3361 * data/c-skel.m4, data/c++-skel.m4: New files.
3362 * data/glr.c: Complain on push parsers.
3364 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
3366 (Decl Summary): Document %language and %skeleton.
3367 (Command line): Document -L.
3369 * examples/extexi: Rewrite %require directive.
3370 * examples/calc++/Makefile.am: Pass VERSION to extexi.
3372 * src/files.c (compute_exts_from_gc): Look in language structure
3374 (compute_file_name_parts): Check whether .tab should be added.
3375 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
3376 (language, skeleton_arg, language_argmatch): New.
3377 (long_options): Add --language.
3378 (getargs): Use skeleton_arg, add -L/--language.
3379 * src/getargs.h: Include location.h.
3380 (struct bison_language, language, skeleton_arg, language_argmatch): New.
3381 * src/output.c (prepare): Pick default skeleton from struct language.
3382 Don't dispatch C skeletons here.
3383 * src/parse-gram.y (PERCENT_LANGUAGE): New.
3384 (prologue_declaration): Add "%language" rule, use skeleton_arg.
3385 * src/scan-gram.l ("%language"): New rule.
3387 * tests/calc.at: Test %skeleton and %language.
3388 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
3389 (AT_GLR_IF): Look for %skeleton "glr.cc".
3390 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
3391 (AT_YACC_IF): Reject %language.
3393 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3395 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
3396 since it wasn't used; only the typedef name 'semantic_type' is needed.
3397 Also, omit trailing white space.
3399 * bootstrap: Sync from coreutils.
3400 (gnulib_extra_files): Add build-aux/announce.gen.
3401 (slurp): Adjust .gitignore files like .cvsignore files.
3402 * build-aux/announce-gen: Remove from CVS, since bootstrap
3405 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
3407 Make %push-parser imply %pure-parser. This fixes several bugs; see
3408 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
3409 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
3411 * data/push.c: Don't bother testing b4_push_if when deciding whether
3412 to expand b4_declare_parser_variables globally.
3413 (yypush_parse): Likewise in here.
3415 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
3416 (yy_reduce_print): Reformat M4 for readability.
3418 2006-12-15 Bob Rossi <bob@brasko.net>
3419 and Joel Denny <jdenny@ces.clemson.edu>
3421 * data/push.c (yypstate): Add typedef, and update all uses of
3422 struct yypstate to just yypstate.
3423 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
3425 2006-12-14 Bob Rossi <bob@brasko.net>
3427 * data/push.c (yypush_parse): Declare prototype regardless of
3430 2006-12-14 Bob Rossi <bob@brasko.net>
3432 * data/push.c (yyparse): Remove the prototype and the #define when in
3435 2006-12-13 Bob Rossi <bob@brasko.net>
3437 * data/push.c (yypstate_init): Rename to...
3438 (yypstate_new): ... this and use b4_c_function_def.
3439 (yypstate_delete): New.
3440 (yypush_parse): Change parameters yynval and yynlloc to be const.
3441 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
3442 yypstate_delete functions.
3444 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
3446 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
3447 strange test case titles. Reported by Bob Rossi.
3449 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
3451 * TODO: Add pointer to Sylvain Schmitz's work on static detection
3452 of potential ambiguities in GLR grammers.
3454 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
3456 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
3457 `bison ', use m4_index instead of m4_substr since chopping up a string
3458 containing M4-special characters causes problems here.
3460 Fix a couple of bugs related to special characters in user-specified
3461 file names, and make it easier for skeletons to compute output file
3462 names with the same file name prefix as Bison-computed output file
3464 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
3465 b4_parser_file_name and b4_spec_defines_file instead of
3466 @output_parser_name@ and @output_header_name@, which are now redundant.
3467 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
3468 b4_parser_file_name, b4_spec_defines_file, and the new
3469 @basename(FILENAME@) instead of @output_parser_name@ and
3470 @output_header_name@, which inappropriately escaped the file names as
3472 * src/files.c (all_but_ext): Remove static qualifier.
3473 (compute_output_file_names): Move `free (all_but_ext)' to...
3474 (output_file_names_free): ... here since all_but_ext is needed later.
3475 * src/files.h (all_but_ext): Extern.
3476 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
3477 exactly what MUSCLE_INSERT_STRING used to do.
3478 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
3479 characters are escaped properly.
3480 * src/output.c (prepare): Define muscle file_name_all_but_ext as
3482 For pkgdatadir muscle, maintain previous functionality by using
3483 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
3484 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
3485 digraphs would never be expanded. Hopefully no one has M4-special
3486 characters in his Bison installation path.
3487 * src/scan-skel.l: Don't parse @output_header_name@ and
3488 @output_parser_name@ anymore since they're now redundant.
3489 In @output, use decode_at_digraphs.
3490 Parse a new @basename command that invokes last_component.
3491 (decode_at_digraphs): New.
3492 (BASE_QPUTS): Remove unused.
3493 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
3494 (Output file name): New tests.
3496 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
3498 Warn about output files that are generated by the skeletons and that
3499 conflict with other output files.
3500 * data/glr.c: Don't generate the header file here when glr.cc does.
3501 * src/files.c (file_names, file_names_count): New static globals.
3502 (compute_output_file_names): Invoke output_file_name_check for files
3503 not generated by the skeletons and remove existing checks.
3504 (output_file_name_check): New function that warns about conflicting
3506 (output_file_names_free): Free file_names.
3507 * src/files.h (output_file_name_check): Declare.
3508 * src/scan-skel.l: Invoke output_file_name_check for files generated by
3510 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
3511 (Conflicting output files): New tests.
3513 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3515 * doc/bison.texinfo: Fix a couple of typos.
3517 2006-12-08 Bob Rossi <bob@brasko.net>
3519 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
3521 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
3523 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
3524 (yypush_parse): Rename yypvars argument to yyps and remove redundant
3526 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
3527 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
3529 2006-12-07 Bob Rossi <bob@brasko.net>
3530 and Joel Denny <jdenny@ces.clemson.edu>
3532 * data/push.c (yypvarsinit): Change return type from void* to struct
3533 yypvars*. No longer cast to void* on return.
3534 (struct yypvars): Remove yylen since it need not be remembered between
3535 yypushparse invocations.
3536 (yypushparse): Don't copy between yylen and pv->yylen.
3538 2006-12-05 Bob Rossi <bob@brasko.net>
3540 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
3541 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
3542 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
3543 (struct yypvars): Remove b4_declare_parser_variables.
3544 (yypvarsinit): Remove init code for removed variables.
3545 (global scope): Do not declare b4_declare_parser_variables if
3547 (yypushparse): Add b4_declare_parser_variables.
3548 Init new local variables, and remove init code for removed
3551 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
3552 and yyparse for other modes.
3553 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
3554 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
3555 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
3556 (AT_PURE_LEX_IF): True if pure or push parser.
3558 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>

3634 grammar is maintained with Bison's highest standards.

3639 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
3640 later. Reported by Paul Eggert in
3641 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.

3658 const. aver that the value and storage are the same since storage
3659 could potentially be NULL when value is not.
3660 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
3663 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3665 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
3666 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
3667 us a slightly cleaner distribution, and also works.
3668 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
3671 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
3672 and Paul Eggert <eggert@cs.ucla.edu>
3674 Don't let Bison leak memory except when it complains.
3675 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
3676 (spec_defines_file, dir_prefix): Now char *, not const char *,
3677 since they are freed.
3678 * src/files.c: Likewise.
3679 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
3681 (tr): Now operates in-place. All uses changed.
3682 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
3684 (compute_file_name_parts, compute_output_file_names): Don't store
3685 read-only data in variables that will be freed.
3686 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
3687 src_extension, and header_extension.
3688 (output_file_names_free): New public function to free
3689 spec_verbose_file, spec_graph_file, spec_defines_file,
3690 parser_file_name, and dir_prefix.
3691 * src/getargs.c (getargs): Don't store read-only data in variables that
3693 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
3694 (which previously existed but was unused), and quotearg_free.
3695 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
3696 * src/muscle_tab.c: Likewise.
3697 (muscle_entry): Make the value char const *,
3698 and add a new storage member that is char * and can be freed.
3699 (muscle_entry_free): New private function.
3700 (muscle_init): Use it instead of free.
3701 (muscle_insert, muscle_grow): Update and use new storage member.
3702 (muscle_code_grow): Free the string passed to muscle_grow
3703 since it's not needed anymore.
3704 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
3705 add a new `char *code' member.
3706 ("{...}"): Declare semantic type as code.
3707 * src/scan-code.h (translate_rule_action):
3708 (translate_symbol_action, translate_code, translate_action): Return
3709 `char const *' rather than `char *' since external code should not free
3711 * src/scan-code.l: Likewise.
3712 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
3713 which is "{...}" in the parser.
3714 * tests/Makefile.am (maintainer-check-valgrind): Set
3715 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
3717 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
3719 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
3720 expecting a non-zero exit status sets --leak-check=summary and
3721 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
3722 this case, and we don't want to hear about it.
3724 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3726 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
3727 instead of from the template, to simplify configuration a bit.
3728 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
3729 and m4/wint_t.m4, as they are needed with the latest gnulib.

3743 declarations): Run tests with and without --warnings=midrule-values.
3745 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
3746 than LIST_FREE directly.
3748 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

3767 empty subargument list. For example: `bison --warnings= parser.y'.
3769 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
3771 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
3772 the parser header file so that gcc doesn't warn.
3774 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
3776 Split the default %destructor/%printer into two kinds: <*> and <!>.

3822 Don't apply the default %destructor/%printer to an unreferenced midrule
3824 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
3825 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
3826 like $@n instead of just @n so that the default %destructor/%printer
3827 logic doesn't see them as user-defined symbols.
3828 (symbol_is_dummy): Check for both forms of the name.
3829 * src/reader.c (packgram): Remove the `$' from each midrule symbol
3830 name for which the midrule value is referenced in any action.

3841 (packgram): Before invoking grammar_rule_check on any rule, make sure
3842 all actions have already been scanned in order to set `used' flags.
3843 Otherwise, checking that a midrule's $$ is set will not always work
3844 properly because the midrule check must forward-reference the midrule's

3858 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
3860 Similar to the recently removed %before-header, add %code-top as the
3861 alternative to the pre-prologue. Mentioned at

3971 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
3973 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
3974 variable was sometimes used without being initialized. This
3975 messed up the installation of the INSTALL file in some cases.
3977 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
3979 * bootstrap (usage, main program, symlink_to_gnulib): Add option
3980 --copy. Inspired by a suggestion from Bruno Haible.
3982 2006-10-03 Jim Meyering <jim@meyering.net>
3984 * bootstrap: Undo last change to this file, since now gnulib-tool
3985 sticks with the automake default in generating dependencies.
3987 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3989 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

4080 Fix problems with translating English-language diagnostics.
4081 * bootstrap: Fix bug introduced in recent bootstrap changes, with

4083 wasn't being captured.
4084 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
4085 * po/POTFILES.in: Add src/location.c, src/scan-code.l.

4092 2006-09-28 Jim Meyering <jim@meyering.net>
4094 Automatically generated dependencies are important even
4095 when all of the sources in a directory come from gnulib.
4096 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
4097 option that gnulib-tool adds to what becomes our lib/gnulib.mk.

4115 2006-09-20 Bob Rossi <bob@brasko.net>
4117 * data/push.c (yyresult_get): Remove function.
4118 (YYPUSH_MORE): Add #define.
4119 (yypushparse): Modify return value.
4121 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
4123 * stamp-h.in: Remove; no longer needed.
4124 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
4125 Remove config.h, config.hin, intl (no longer created).
4126 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
4129 Sync bootstrap from coreutils, as follows:
4131 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
4133 * bootstrap (symlink_to_gnulib): New function.
4134 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
4135 to copies-of-gnulib.
4136 (cp_mark_as_generated, slurp, gnulib_files):
4137 Avoid making a copy if it's the same as the old version.
4138 (gnulib_files): Add support for this variable (used by Bison).
4140 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
4142 * src/getargs.c (usage): Rework to use conventions similar to
4143 coreutils, to make translation a bit easier and the code a bit
4144 smaller. Problem reported by Tim Van Holder.
4146 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
4148 Use some of gnulib's new modules, taken from coreutils.
4150 * bootstrap: Sync from coreutils, except add support for gnulib_files.
4151 * bootstrap.conf: New file.
4152 (gnulib_modules): Add configmake, inttypes, unistd.
4153 (XGETTEXT_OPTIONS): Add complain, complain_at,
4154 fatal, fatal_at, warn, warn_at, unexpected_end.
4155 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
4156 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
4158 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
4160 (GNULIB_AUTOCONF_SNIPPET): Remove.
4161 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
4163 * lib/.cvsignore: Add inttypes_.h.
4164 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
4165 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
4166 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
4167 no-longer-necessary initializations.
4168 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
4169 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
4170 use the unistd module.
4171 * src/system.h: Likewise.
4172 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
4173 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
4174 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
4175 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
4176 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
4177 * src/system.h: Include inttypes.h unconditionally, now that we
4178 use the inttypes module. Don't bother to include stdint.h, since
4179 inttypes.h now does that for us.
4180 (LOCALEDIR): Remove, now that we use the configmake module.
4181 * src/getargs.c: Include configmake.h.
4182 * src/main.c: Likewise.
4183 * src/output.c: Likewise.
4184 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
4185 not from $abs_top_builddir, since config.h moved.
4188 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
4189 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
4191 * src/parse-gram.y (symbol_declaration): Don't put statements
4192 before declarations; it's not portable to C89.
4193 * src/scan-code.l (handle_action_at): Likewise.
4195 * src/scan-code.l: Always initialize braces_level; the old code
4196 left it uninitialized and therefore had undefined behavior.
4198 Don't attempt to redefine 'assert', since it runs afoul of
4199 systems where standard headers (mistakenly) include <assert.h>.
4200 Instead, define and use our own alternative, called 'aver'.
4201 * src/reader.c: Don't include assert.h, since we no longer
4203 * src/scan-code.l: Likewise.
4204 * src/system.h (assert): Remove, replacing with....
4205 (aver): New function, taking a bool arg. All uses changed.
4206 * src/tables.c (pack_vector): Ensure that aver arg is bool,
4207 not merely an integer.
4209 2006-09-15 Bob Rossi <bob@brasko.net>
4211 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
4212 * data/c.m4 (YYPUSH): New.
4213 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
4214 * src/getargs.c (push_parser): New var.
4215 * src/getargs.h (push_parser): New declaration.
4216 * src/output.c (prepare): Add macro insertion of `push_flag'.
4217 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
4218 (prologue_declaration): Parse %push-parser.
4219 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
4220 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
4221 list of removed lines from the traces observed.
4222 (AT_CHECK_CALC_LALR): Added push parser tests.
4224 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
4226 * NEWS: Version 2.3a.
4227 * configure.ac (AC_INIT): Likewise.
4229 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
4230 "#define YYSTYPE int" that caused "make maintainer-check" to fail
4231 due to header ordering dependencies. I don't know why the #define
4234 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
4235 runtime cost when YYDEBUG is not defined, and so that some tests
4236 that used to fail now work. Problem and initial suggestion by
4238 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
4239 * data/glr.cc (b4_parser_class_name):
4240 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
4241 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
4242 (yydebug_) [YYDEBUG]: New member.
4243 (yycdebug_): Now defined only if YYDEBUG.
4244 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
4245 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
4246 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
4248 (debug_stream, set_debug_stream, debug_level, set_debug_level):
4249 Define only if YYDEBUG.
4250 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
4252 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
4253 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
4254 AT_CHECK_CALC_GLR_CC that are working now.
4256 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
4258 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
4259 We don't need them in glr.cc, and glr.c defines them.
4260 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
4261 assumes that defining it to anything is the same as defining
4262 it to 1. Problem reported by Paolo Bonzini.
4264 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
4266 * data/c.m4 (b4_null, b4_case): Define.
4267 * src/output.c (prepare_symbols): Use b4_null.
4268 (user_actions_output): Use b4_case.
4270 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
4272 * data/glr.c (b4_shared_declarations): Put start-header first,
4273 before any #includes that we generate, so that feature-test
4274 macros work. Problem reported by Michael Deutschmann in
4275 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
4276 * data/lalr1.cc: Likewise.
4277 * doc/bison.texinfo (Prologue): Document that feature-test macros
4278 should be defined before any Bison declarations.
4279 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
4280 that depend on location.hh after, not before, Bison decls, since
4281 we now include location.hh after the first user prologue.
4283 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
4284 Sander Brandenburg in
4285 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
4286 Also, fix minor white space and comment issues.
4287 (Prologue): Mention that it's better to define feature-test macros
4288 before Bison declarations. Problem reported by Michael Deutschmann.
4290 * README-cvs: Fix typo: "&" should be "&&". Problem reported
4292 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
4293 This adjusts to recent gnulib changes.
4295 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4297 Finish implementation of per-type %destructor/%printer. Discussed
4299 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
4301 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
4302 * NEWS (2.3+): Add a description of this feature to the default
4303 %destructor/%printer description.
4304 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
4305 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4306 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
4307 list node contains a semantic type.
4308 * src/symtab.c, src/symtab.h: Extend with a table that associates
4309 semantic types with their %destructor's and %printer's.
4310 (semantic_type_from_uniqstr, semantic_type_get,
4311 semantic_type_destructor_set, semantic_type_printer_set): New functions
4312 composing the public interface of that table.
4313 (symbol_destructor_get, symbol_destructor_location_get,
4314 symbol_printer_get, symbol_printer_location_get): If there's no
4315 per-symbol %destructor/%printer, look up the per-type before trying
4317 * tests/actions.at (Per-type %printer and %destructor): New test case.
4318 * tests/input.at (Default %printer and %destructor redeclared):
4319 Extend to check that multiple occurrences of %symbol-default in a
4320 single %destructor/%printer declaration is an error.
4321 (Per-type %printer and %destructor redeclared, Unused values with
4322 per-type %destructor): New test cases.
4324 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4326 Require default %destructor/%printer to be declared using
4327 %symbol-default instead of an empty symbol list, and start working on
4328 new per-type %destructor/%printer. Discussed at
4329 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
4330 * NEWS (2.3+): Add %symbol-default to example.
4331 * bison.texinfo (Freeing Discarded Symbols): Likewise.
4332 (Table of Symbols): Add entry for %symbol-default.
4333 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
4334 (generic_symlist, generic_symlist_item): New nonterminals for creating
4335 a list in which each item is a symbol, semantic type, or
4337 (grammar_declaration): Use generic_symlist in %destructor and %printer
4338 declarations instead of symbols.1 or an empty list.
4339 (symbol_declaration, precedence_declaration, symbols.1): Update actions
4340 for changes to symbol_list.
4341 * src/reader.c: Update for changes to symbol_list.
4342 * src/scan-code.l: Likewise.
4343 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
4344 * src/symlist.c, src/symlist.h: Extend such that a list node may
4345 represent a semantic type or a %symbol-default in addition to just an
4346 ordinary symbol. Add switched functions for setting %destructor's and
4348 * tests/actions.at, tests/input.at: Add %symbol-default to all default
4349 %destructor/%printer declarations.
4351 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
4353 Whether the default %destructor/%printer applies to a particular symbol
4354 isn't a question of whether the user *declares* that symbol (in %token,
4355 for example). It's a question of whether the user by any means
4356 *defines* the symbol at all (by simply using a char token, for
4357 example). $end is defined by Bison whereas any other token with token
4358 number 0 is defined by the user. The error token is always defined by
4359 Bison regardless of whether the user declares it with %token, but we
4360 may one day let the user define error as a nonterminal instead.
4361 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
4362 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
4363 the meaning of "user-defined".
4364 * tests/actions.at (Default %printer and %destructor for user-declared
4365 end token): Rename to...
4366 (Default %printer and %destructor for user-defined end token): ...
4369 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
4370 computation of whether to apply the default, don't maintain a list of
4371 every Bison-defined symbol. Instead, just check for a first character
4372 of '$', which a user symbol cannot have, and check for the error token.
4374 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
4376 Don't apply the default %destructor or %printer to the error token,
4377 $undefined, or $accept. This change fits the general rule that the
4378 default %destructor and %printer are only for user-declared symbols,
4379 and it solves several difficulties that are described in the new test
4381 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
4382 * tests/actions.at (Default %printer and %destructor are not for error
4383 or $undefined, Default %printer and %destructor are not for $accept):
4386 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
4388 Allow %start after the first rule.
4389 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
4390 when parsing the first rule.
4391 (check_and_convert_grammar): Search for it here after all grammar
4392 declarations have been parsed. Skip midrules, which have dummy LHS
4394 * src/symtab.c (symbol_is_dummy): New function.
4395 * src/symtab.h (symbol_is_dummy): Declare it.
4396 * tests/input.at (%start after first rule): New test.
4398 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4400 Redo some of the previous commit: add back the ability to use
4401 non-aliased/undeclared string literals since it might be useful to
4402 those declaring %token-table.
4403 * src/reader.c (check_and_convert_grammar): Undo changes in previous
4404 commit: don't worry about complaints from symbols_pack.
4405 * src/symtab.c (symbol_new, symbol_class_set,
4406 symbol_check_alias_consistency): Undo changes in previous commit: count
4407 each string literal as a new symbol and token, assign it a symbol
4408 number, and don't complain about non-aliased string literals.
4409 (symbols_pack): Since symbol_make_alias still does not decrement symbol
4410 and token counts but does still set aliased tokens to the same number,
4411 symbol_pack_processor now leaves empty slots in the symbols array.
4413 * tests/regression.at (Undeclared string literal): Remove test case
4414 added in previous commit since non-aliased string literals are allowed
4416 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
4417 remove unnecessary string literal declarations.
4418 * tests/sets.at (Firsts): Likewise.
4420 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4422 Don't allow an undeclared string literal, but allow a string literal to
4423 be used before its declaration.
4424 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
4425 symbols_pack complained.
4426 * src/symtab.c (symbol_new): Don't count a string literal as a new
4428 (symbol_class_set): Don't count a string literal as a new token, and
4429 don't assign it a symbol number since symbol_make_alias does that.
4430 (symbol_make_alias): It's not necessary to decrement the symbol and
4431 token counts anymore. Don't assume that an alias declaration occurs
4432 before any uses of the identifier or string, and thus don't assert that
4433 one of them has the highest symbol number so far.
4434 (symbol_check_alias_consistency): Complain if there's a string literal
4435 that wasn't declared as an alias.
4436 (symbols_pack): Bail if symbol_check_alias_consistency failed since
4437 symbol_pack asserts that every token has been assigned a symbol number
4438 although undeclared string literals have not.
4439 * tests/regression.at (String alias declared after use, Undeclared
4440 string literal): New test cases.
4441 (Characters Escapes, Web2c Actions): Declare string literals as
4443 * tests/sets.at (Firsts): Likewise.
4445 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
4447 In the grammar scanner, STRING_FINISH unclosed constructs and return
4448 them to the parser in order to improve error messages.
4449 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
4450 SC_BRACED_CODE, SC_PROLOGUE): Implement.
4451 * tests/input.at (Unclosed constructs): New test case.
4452 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
4455 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
4458 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
4460 Handle string aliases for character tokens correctly.
4461 * src/symtab.c (symbol_user_token_number_set): If the token has an
4462 alias, check and set its alias's user token number instead of its own,
4463 which is set to indicate the alias. Previously, every occurrence of
4464 the character token in the grammar overwrote that alias indicator with
4466 * tests/input.at (String aliases for character tokens): New test.
4468 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
4470 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
4472 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
4474 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
4475 to prevent failures when building on older platforms.
4476 Check for autopoint failure.
4477 Set XGETTEXT_OPTIONS to values that check for C format strings,
4478 so that translators are warned about them (this also helps
4479 prevent core dumps).
4481 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
4482 function, since it simplifies our code a bit.
4484 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
4485 rather than -W, so we don't get bogus warnings about sign comparisons.
4486 Add -Wpointer-arith, since that warning is useful (it reports code
4487 that does not conform to C89 and that some compilers reject).
4488 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
4489 since it's no longer needed.
4491 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
4493 Clean up scanners a bit.
4494 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
4495 definitions so gcc won't warn when obstack_for_string is unused.
4496 * src/scan-code.l: config.h and system.h are already #include'd by
4497 scan-code-c.c, so get rid of them here.
4498 * src/scan-gram.l: Likewise.
4499 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
4500 definitions rather than duplicating the rest of it.
4501 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
4503 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
4505 Suppress signed/unsigned comparison warnings for yycheck.
4506 * data/c.m4 (b4_safest_int_type): New macro.
4507 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
4508 a signed int type, cast it to b4_safest_int_type first.
4509 * data/yacc.c: Likewise.
4510 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
4513 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
4515 * doc/bison.texinfo: Fix some typos.
4517 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
4519 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
4520 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
4522 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
4523 the latest gnulib does this a different way.
4524 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
4525 translation was patched, so stop omitting it.
4527 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
4529 Enable declaration of default %printer/%destructor. Make the parser
4530 use these for all user-declared grammar symbols for which the user does
4531 not declare a specific %printer/%destructor. Thus, the parser uses it
4532 for token 0 if the user declares it but not if Bison generates it as
4533 $end. Discussed starting at
4534 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
4535 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
4537 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
4538 * NEWS (2.3+): Mention.
4539 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
4540 declare a %destructor for a mid-rule's semantic value. It's just
4541 impossible to declare one specific to it.
4542 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
4543 code. Describe default %destructor form.
4544 * src/parse-gram.y (grammar_declaration): Parse default
4545 %printer/%destructor declarations.
4546 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
4547 and symbol_destructor_location_get rather than accessing the destructor
4548 and destructor_location members of struct symbol.
4549 (symbol_printers_output): Likewise but for %printer's.
4550 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
4552 * src/symtab.c (default_destructor, default_destructor_location,
4553 default_printer, default_printer_location): New static global
4554 variables to record the default %destructor and %printer.
4555 (symbol_destructor_get, symbol_destructor_location_get,
4556 symbol_printer_get, symbol_printer_location_get): New functions to
4557 compute the appropriate %destructor and %printer for a symbol.
4558 (default_destructor_set, default_printer_set): New functions to set the
4559 default %destructor and %printer.
4560 * src/symtab.h: Prototype all those new functions.
4561 * tests/actions.at (Default %printer and %destructor): New test to
4562 check that the right %printer and %destructor are called, that they're
4563 not called for $end, and that $$ and @$ work correctly.
4564 (Default %printer and %destructor for user-declared end token): New
4565 test to check that the default %printer and %destructor are called for
4566 a user-declared end token.
4567 * tests/input.at (Default %printer and %destructor redeclared, Unused
4568 values with default %destructor): New tests to check related grammar
4569 warnings and errors.
4571 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
4573 Clean up handling of %destructor for the end token (token 0).
4574 Discussed starting at
4575 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
4577 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
4579 Make the skeletons consistent in how they pop the end token and invoke
4581 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
4582 state, which has token number 0, since this would invoke the
4583 %destructor for the end token.
4584 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
4585 until after shifting the end token, or else it won't be popped.
4586 * data/yacc.c (yyparse): Likewise.
4588 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
4589 it's the end token. Upon termination, destroy an unshifted lookahead
4590 even when it's the end token.
4591 * data/lalr1.cc (yy::parser::parse): Likewise.
4592 * data/yacc.c (yyparse): Likewise.
4594 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
4595 value warnings for the end token when the user gives the end token a
4598 * tests/actions.at (Printers and Destructors): Test all the above.
4600 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
4602 Update to latest gnulib and gettext versions.
4603 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
4605 (gnulib_files): Add m4/warning.m4. Don't worry about files
4606 overwritten by autopoint.
4607 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
4608 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
4610 Don't use autoreconf; instead, invoke autopoint etc. by hand,
4611 so that we can remove the intl files at a better time.
4612 (intl_files_to_remove): Remove aclocal.m4, since it gets
4613 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
4614 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
4615 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
4616 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
4617 Remove datarootdir hack; no longer needed.
4618 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
4619 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
4620 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
4622 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
4623 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
4625 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4627 * bootstrap: Adjust to today's change to gnulib-tool by invoking
4628 it with --assume-autoconf='latest-stable'.
4630 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
4632 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
4633 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
4635 * src/muscle_tab.h (muscle_grow): Replace the header comments with
4636 those from muscle_tab.c since the old ones are misleading.
4638 2006-07-13 Akim Demaille <akim@epita.fr>
4640 Support %define "KEY" {VALUE}.
4641 * src/scan-code.h, src/scan-code.l (translate_action)
4642 (translate_rule_action, translate_symbol_action, translate_code):
4643 Return char *, not const char *.
4644 * src/parse-gram.y (declaration): Rename as...
4645 (prologue_declaration): this.
4646 (string_content): Remove this nonterminal, use STRING.
4647 (braceless, content, content.opt): New nonterminal.
4649 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
4651 * src/scan-gram.l (getargs.h): Don't include it.
4653 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
4655 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
4656 rather than a for-loop that declares a local bool variable. This
4657 should work around a compatibility problem with a Cray x1e C++
4658 compiler reported by Hung Nguyen in
4659 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
4660 The for-loop was introduced in the 2004-11-17 change but I don't
4661 know why it was needed.
4663 2006-07-12 Akim Demaille <akim@epita.fr>
4665 * data/c.m4: Comment changes.
4667 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
4669 * src/complain.c (error_message, ERROR_MESSAGE): New.
4671 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
4672 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
4674 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4676 * NEWS: Instead of %union, you can define and use your own union type
4677 YYSTYPE if your grammar contains at least one <type> tag.
4678 Your YYSTYPE need not be a macro; it can be a typedef.
4679 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
4680 (Union Decl, Decl Summary): Document this.
4681 * data/glr.c (YYSTYPE): Implement this.
4682 * data/glr.cc (YYSTYPE): Likewise.
4683 * data/lalr1.cc (YYSTYPE): Likewise.
4684 * data/yacc.c (YYSTYPE): Likewise.
4685 * src/output.c (prepare): Output tag_seen_flag.
4686 * src/parse-gram.y (declaration, grammar_declaration):
4687 Use 'union_seen' rather than 'typed' to determine whether
4688 %union has been seen, since grammars can now be typed without
4690 (symbol_declaration, type.opt, symbol_def):
4691 Keep track of whether a tag has been seen.
4692 * src/reader.c (union_seen, tag_seen): New vars.
4694 * src/reader.h (union_seen, tag_seen, typed): Likewise.
4695 * src/scan-code.l (untyped_var_seen): New variable.
4696 (handle_action_dollar): Adjust to above changes.
4697 (handle_action_dollar, handle_action_at):
4698 Improve overflow checking for outlandish numbers.
4699 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
4700 avoid new diagnostics generated by above changes.
4701 * tests/regression.at (YYSTYPE typedef): Add test to check
4702 for type tags without %union.
4704 * src/symlist.c (symbol_list_length): Return int, not unsigned
4705 int, since callers expect int. This may need to get revisited
4706 once we have proper integer overflow checking.
4708 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
4709 object is now static.
4711 * src/getargs.c (flags_argmatch): Return void, not int,
4712 to pacify ./configure --enable-gcc-warnings.
4714 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
4715 since last_string is already defined to FLEX_PREFIX (last_string).
4717 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4719 Implement --warnings/-W.
4720 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
4722 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
4724 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
4725 (warnings_args, warnings_types): New.
4726 (getargs, short_options, long_options): Accept -W/--warnings.
4727 Sort the options by alphabetical order, upper case letter right
4728 before its lower case.
4730 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
4732 Change %merge result type clash warnings to errors. Discussed at
4733 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
4734 * src/reader.c (record_merge_function_type): Use complain_at.
4735 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4736 declared later): Update test case results.
4738 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4740 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
4741 to be in alphabetical order.
4742 (trace_args): Spelling fixes.
4744 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4746 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
4747 so they don't collide with user-defined macros.
4748 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
4749 this was never guaranteed, and now that we're using gnulib stdint,
4750 which defines int_fast16_t to long int, the problem is exposed.
4752 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
4754 * data/c.m4 (b4_basename): Simplify a bit, since we don't
4755 need the full POSIX semantics (and weren't implementing them
4758 Adjust to Autoconf 2.60 and today's gnulib.
4759 * bootstrap (gnulib_modules): Add stdint.
4760 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
4761 no longer copies it.
4762 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
4763 since stdint needs the former and wcwidth (which is now required
4764 by mbswidth) needs the latter.
4765 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
4766 work around a compatibility glitch between gettext 0.14.6 and
4768 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
4769 Do not check for uintptr_t, since new stdint module does the right
4771 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
4772 Add stdint.h, stdint_.h, wcwidth.h.
4773 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
4774 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
4775 stdint.m4, wchar_t.m4, wcwidth.m4.
4776 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
4777 usual order for ../lib/*.h files.
4778 (file_name_split): Use last_component, not base_name, to adjust
4780 * src/parse-gram.h: Include <strverscmp.h> in the usual order
4781 for ../lib/*.h files.
4782 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
4783 Define unconditionally, since we now assume the stdint module.
4784 * src/scan-skel.l: Include <dirname.h>.
4785 (BASE_QPUTS): Use last_component, not base_name.
4786 * src/system.h: Include <unlocked-io.h> in the usual order
4787 for ../lib/*.h files. Include <stdint.h> unconditionally,
4788 since we now use the stdint module.
4789 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
4790 HAVE_UINTPTR_T, since we now use the stdint module.
4791 (base_name): Remove decl, since files now include <dirname.h>
4794 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4796 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
4798 * data/yacc.c, data/glr.c, data/location.cc: Use them.
4799 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
4801 * tests/calc.at: Adjust.
4803 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4805 * data/c.m4 (b4_basename): New.
4806 (b4_syncline): Also output the location of its invocation (from
4808 (b4_user_action, b4_define_user_action, b4_user_actions)
4809 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
4810 (b4_user_stype): New.
4811 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
4813 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4815 In the grammar file, the first column is 1 not 0 on the first line as
4816 on every other line.
4817 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
4818 * tests/input.at (Torturing the Scanner): Update output.
4820 * src/scan-gram.l (scanner_cursor): Declare it static.
4822 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4824 In warnings, say "previous declaration" rather than "first
4826 * src/symtab.c (redeclaration): Do that here.
4827 * src/reader.c (record_merge_function_type): In the case of a result
4828 type clash, report the previous declaration rather than the very first
4829 one in the grammar file.
4830 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4831 declared later): Add a third declaration to check this behavior.
4832 * tests/input.at (Incompatible Aliases): Update output.
4834 2006-06-27 Akim Demaille <akim@epita.fr>
4836 * doc/Doxyfile.in: New.
4837 * doc/Makefile.am: Use it.
4838 * src/lalr.h, src/symtab.h: Initial doxygenation.
4840 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4842 Don't miss %merge result type warnings just because the LHS types are
4843 declared after the %merge. This continues the effort of the previous
4845 * src/reader.c (get_merge_function): Don't set the merger type yet.
4846 (record_merge_function_type): New function for setting the merger type
4847 and checking for clashes.
4848 (grammar_current_rule_merge_set): Set the location of the %merge for
4850 (packgram): Invoke record_merge_function_type for each rule now that
4851 all symbol type declarations have been parsed.
4852 * src/reader.h (merger_list.type_declaration_location): New member
4853 storing the location of the first %merge from which the type for this
4854 merging function was derived.
4855 * src/symlist.h (symbol_list.merger_declaration_location): New member
4856 storing the location of a rule's %merge, if any.
4857 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4858 declared later): New test to catch the error fixed by the above patch.
4860 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4862 Get action warnings (grammar_rule_check) right even when symbol
4863 declarations appear after the rules. Discussed at
4864 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
4866 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
4867 Don't mistake the type of $$ in a midrule to be that of its parent
4869 * src/reader.c (grammar_current_rule_end): Don't invoke
4870 grammar_rule_check yet since not all symbol declarations may have been
4872 (grammar_midrule_action): Likewise.
4873 Don't record whether the midrule's $$ has been used yet since actions
4874 haven't been translated yet.
4875 Record the midrule's parent rule and its RHS index within the parent
4877 (grammar_current_rule_action_append): Don't translate the action yet
4878 since not all symbol declarations may have been parsed yet and, thus,
4879 warnings about types for $$, $n, @$, and @n can't be reported yet.
4880 (packgram): Translate the action and invoke grammar_rule_check now that
4881 all symbol declarations have been parsed.
4882 * src/scan-code.l (handle_action_dollar): Now that this is invoked
4883 after parsing the entire grammar file, the symbol list here in the case
4884 of a midrule is actually the midrule's empty RHS, so reference its
4885 parent rule's RHS where necessary.
4886 On the other hand, now that you can already know it's a midrule, you
4887 aren't forced to think $$ has the same type as its parent rule's $$.
4888 (handle_action_at): In the case of a midrule, reference the parent rule
4890 * src/symlist.c (symbol_list_new): Initialize new midrule-related
4892 (symbol_list_length): Now that this is invoked after all rules have
4893 been parsed, a NULL symbol (rather than a NULL symbol list node)
4894 terminates a rule. symbol_list_print already does this correctly.
4895 * src/symlist.h (symbol_list.midrule_parent_rule,
4896 symbol_list.midrule_parent_rhs_index): New members so that midrules can
4897 remember their relationships with their parents.
4898 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
4899 fixed by the above patch.
4900 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
4902 (Unused values): ... this old test case and...
4903 (Unused values before symbol declarations): ... this new test case.
4904 This one is the same as `Unused values' except that all symbol
4905 declarations appear after the rules in order to catch the rest of the
4906 errors fixed by the above patch.
4908 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4911 * src/reader.c (current_rule): Declare it static since it's no longer
4912 used outside this file.
4913 (grammar_current_rule_action_append): Remove redundant arguments from
4914 translate_rule_action invocation.
4915 * src/reader.h (current_rule): Remove this unused extern.
4916 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
4917 * src/scan-code.l (translate_rule_action): Likewise.
4919 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
4921 Clean up yesterday's patch.
4922 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
4924 * src/reader.c (grammar_current_rule_action_append): ... here for
4925 consistency with grammar_current_rule_symbol_append.
4926 * tests/regression.at (Braced code in declaration in rules section):
4927 Make yyerror and yylex static as usual.
4929 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
4931 Fix bug that mistakes braced code in a declaration in the rules section
4932 to be a rule action. Mentioned at
4933 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
4934 * src/scan-gram.l: Move midrule action detection from the start of the
4935 scanning of any braced code to...
4936 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
4937 action. For readability, use $2 and @2 rather than the equivalent
4939 * tests/regression.at (Braced code in declaration in rules section):
4940 New test to catch the error fixed by the above patch.
4942 Work on code readability some.
4943 * src/scan-code.l (current_rule): Get rid of this misleading and
4944 redundant declaration: it's actually extern'ed in reader.h.
4945 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
4946 translate_action): Add a rule argument and use it instead of the global
4948 (translate_rule_action): This already receives current_rule through an
4949 argument, so pass it on to translate_action instead of assigning
4950 current_rule to current_rule.
4951 (translate_symbol_action, translate_code): Pass rule = NULL to
4954 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
4956 Rename %before-definitions to %start-header and %after-definitions to
4957 %end-header. Don't use these declarations to separate pre-prologue
4958 blocks from post-prologue blocks. Add new order-independent
4959 declarations %before-header and %after-header as alternatives to the
4960 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
4961 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
4962 * NEWS (2.3+): Update for these changes.
4963 * data/glr.c (b4_before_definitions): Update to...
4964 (b4_start_header): ... this.
4965 (b4_after_definitions): Update to...
4966 (b4_end_header): ... this.
4967 * data/glr.cc: Likewise.
4968 * data/lalr1.cc: Likewise.
4969 * data/yacc.c: Likewise.
4970 * doc/bison.texinfo (The prologue): Update names, and replace remaining
4971 prologue blocks with %*-header declarations.
4972 (Calc++ Parser): Likewise.
4973 (Decl Summary): Update names.
4974 (Table of Symbols): Update description.
4975 * src/parse-gram.y (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 (declaration): Update token names and m4 macro names.
4981 When parsing %end-header and %start-header, invoke translate_code
4982 before muscle_code_grow, and no longer set global booleans to remember
4983 whether these declarations have been seen.
4984 Parse new %after-header and %before-header.
4985 * src/reader.c (before_definitions, after_definitions): Remove.
4986 (prologue_augment): Accept a new bool argument to specify whether to
4987 augment the pre-prologue or post-prologue.
4988 * src/reader.h (before_definitions, after_definitions): Remove these
4990 (prologue_augment): Add new bool argument.
4991 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
4992 (PERCENT_END_HEADER): ... this.
4993 (PERCENT_BEFORE_DEFINITIONS): Update to...
4994 (PERCENT_START_HEADER): ... this.
4995 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
4996 * tests/actions.at (Printers and Destructors): Update names.
4998 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
5000 Add comparison operators for C++ location classes. Discussed at
5001 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
5002 * data/c++.m4 (b4_define_location_comparison): New boolean %define
5003 declaration indicating whether filename_type has an operator==. If
5004 filename_type is `std::string', it defaults to `1', `0' otherwise.
5005 * data/location.cc: Iff b4_define_location_comparison is `1', add
5006 operator== and operator!= for class position and for class location.
5009 * src/scan-action.l: Remove unused file.
5010 * src/symtab.c (symbol_printer_set): Use printer_location not
5011 destructor_location.
5012 * src/symtab.h (struct symbol): Replace incorrect source comment for
5014 * tests/input.at (Incompatible Aliases): Update output with correct
5017 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
5019 Don't put the pre-prologue in the header file. For the yacc.c code
5020 file and the glr.c header and code files, move the pre-prologue before
5021 the token definitions. Add new %before-definitions and
5022 %after-definitions to declare code that will go in both the header file
5023 and code file. Discussed at
5024 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
5025 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
5027 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
5028 * NEWS (2.3+): Describe these changes.
5029 * data/glr.c (b4_pre_prologue): Move from within to before...
5030 (b4_shared_declarations): ... this.
5031 Add new b4_before_definitions before b4_token_enums.
5032 Add new b4_after_definitions at the end.
5033 * data/glr.cc (b4_pre_prologue): Replace with...
5034 (b4_before_definitions): ... this in the header file.
5035 (b4_after_definitions): New near the end of the header file.
5036 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
5037 code file right before including the header file.
5038 (b4_before_definitions): New in the previous position of
5039 b4_pre_prologue in the header file.
5040 (b4_after_definitions): New near the end of the header file.
5041 * data/yacc.c: Clean up some m4 quoting especially in the header file.
5042 (b4_token_enums_defines): In the code file, move to right before
5043 YYSTYPE for consistency with the header file.
5044 (b4_before_definitions): New right before b4_token_enums_defines in
5045 both the header and code file.
5046 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
5047 header and code file.
5048 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
5049 of prologues for %union dependencies.
5050 (Decl Summary): In %defines description, mention the effect of
5051 %before-definitions and %after-definitions on the header file.
5052 (Calc++ Parser): Forward declare driver in a %before-definitions rather
5053 than in the pre-prologue so that make check succeeds.
5054 (Table of Symbols): Add entries for %before-definitions and
5056 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
5057 %before-definitions.
5058 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
5059 (declaration): Parse those declarations and append to
5060 b4_before_definitions and b4_after_definitions, respectively.
5061 * src/reader.c (before_definitions, after_definitions): New bools to
5062 track whether those declarations have been seen.
5063 (prologue_augment): Add to the post-prologue if %union,
5064 %before-definitions, or %after-definitions has been seen.
5065 * src/reader.h (before_definitions, after_definitions): New extern's.
5066 * src/scan-gram.l: Scan the new declarations.
5067 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
5068 prologue block in a %before-definitions or a %after-definitions based
5069 on whether the %union is declared.
5070 * tests/regression.at (Early token definitions with --yacc, Early token
5071 definitions without --yacc): Move tests for token definitions into the
5072 post-prologue since token names are no longer defined in the
5075 2006-06-20 Akim Demaille <akim@epita.fr>
5077 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
5078 (symbol_get): Use it.
5079 * src/parse-gram.y: Use it.
5081 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
5083 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
5084 build succeeds when configured with --enable-gcc-warnings.
5086 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5088 * src/parse-gram.y (char_name): New function.
5089 (CHAR, STRING, string_content): For %printer, properly escape.
5090 (ID): Prefer fputs to fprintf.
5091 (id): Reindent to be consistent with other rules.
5092 Properly quote char.
5094 The Translation Project changed its way of publishing translations
5095 to maintainers. I haven't received any responses to my request
5096 for supporting the old way, or for documenting the new way. I
5097 have modified 'bootstrap' to use screen scraping
5098 (in this case, HTML scraping). This is unreliable and inelegant,
5099 but I don't see any better way. Yuck.
5100 * bootstrap (TP_URL, WGET_COMMAND): New vars.
5101 (get_translations): New function, which uses HTML scraping to
5102 deduce locations of latest translations.
5103 Use this function to grab both bison and bison-runtime .po files.
5104 Don't bother priming the pump for the runtime-po domain any more,
5105 as it's now translated better than bison is.
5107 2006-06-19 Akim Demaille <akim@epita.fr>
5109 * src/scan-gram.l: No longer "parse" things after `%union' until
5110 `{'. Rather, return a single "%union" token.
5111 No longer make symbols: return strings, and leave the conversion
5112 to symbols to the parser.
5113 (SC_PRE_CODE, token_type): Remove.
5114 * src/parse-gram.y (%union): New field `character'.
5117 (ID, ID_COLON): Now that the scanner no longer makes them
5118 identifiers, adjust all uses to invoke symbol_get.
5119 (id_colon): New, wraps the conversion from string to symbol.
5120 (%union): Accept a possible union_name.
5121 (symbol): Now can be a char.
5122 * data/c.m4 (b4_union_name): Leave a default value.
5123 * data/glr.c, data/yacc.c: Use it.
5125 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
5127 For associating token numbers with token names for "yacc.c", don't use
5128 #define statements unless `--yacc' is specified; always use enum
5129 yytokentype. Most important discussions start at:
5130 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
5131 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
5133 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
5134 * NEWS (2.3+): Mention.
5135 * data/c.m4 (b4_yacc_if): New.
5136 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
5138 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
5139 on token name definitions.
5140 * src/getargs.c (usage): Capitalize `Yacc' in English.
5141 * src/output.c (prepare): Define b4_yacc_flag.
5142 * tests/regression.at (Early token definitions): Test that tokens names
5143 are defined before the pre-prologue not just before the post-prologue.
5144 Remove this test case and copy to...
5145 (Early token definitions with --yacc): ... this to test #define's.
5146 (Early token definitions without --yacc): ... and this to test enums.
5148 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
5150 * NEWS: Reword the post-2.3 change to not be so optimistic about
5151 removing the old "look-ahead" spelling.
5152 Update previous look-ahead/lookahead change reports.
5153 * REFERENCES: look-ahead -> lookahead (since that's
5154 what he actually wrote).
5155 * doc/refcard.tex: look ahead -> lookahead,
5156 look-ahead -> lookahead
5158 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
5160 For consistency, use `lookahead' instead of `look-ahead' or
5161 `look_ahead'. Discussed starting at
5162 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>

5231 2006-06-08 Joel E. Denny <jdenny@ces.clemson.edu>
5233 * src/flex-scanner.h (yytext): Remove stray `*/' in #define.
5235 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5237 * TODO: Add request from Nelson H. F. Beebe to be able to install
5238 Bison without installing the yacc script.
5240 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5242 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
5243 and yytext if they're already #define'd.
5244 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
5245 * src/scan-code-c.c: ... here.
5246 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
5249 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5251 Get Bison to build again when configured with --enable-gcc-warnings.
5252 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
5254 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
5255 loc argument as it shadows a global.
5256 * src/scan-gram.l: Remove stray comma that prevents boundary_set
5259 * src/.cvsignore: Add scan-code.c.
5261 2006-06-07 Akim Demaille <akim@epita.fr>
5263 * src/scan-gram.l: Move the "add a trailing ; to actions" code
5265 * src/scan-code.l: here.
5266 * tests/input.at (Torturing the Scanner): Fix another location
5269 2006-06-07 Akim Demaille <akim@epita.fr>
5271 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
5273 2006-06-06 Akim Demaille <akim@epita.fr>
5275 Extract the parsing of user actions from the grammar scanner.
5276 As a consequence, the relation between the grammar scanner and
5277 parser is much simpler. We can also split "composite tokens" back
5279 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
5280 * src/scan-gram.l (add_column_width, adjust_location): Move to and
5282 * src/location.h, src/location.c (add_column_width)
5283 (location_compute): these.
5284 Fix the column count: the initial column is 0.
5285 (location_print): Be robust to ending column being 0.
5286 * src/location.h (boundary_set): New.
5287 * src/main.c: Adjust to scanner_free being renamed as
5289 * src/output.c: Include scan-code.h.
5290 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
5292 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
5293 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
5294 which is now, again, a separate token.
5295 Adjust all dependencies.
5296 Whereever actions with $ and @ are used, use translate_code.
5297 (action): Remove this nonterminal which is now useless.
5298 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
5299 (grammar_current_rule_action_append): Use translate_code.
5300 (packgram): Bound check ruleno, itemno, and rule_length.
5301 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
5302 (last_string, last_braced_code_loc, max_left_semantic_context)
5303 (scanner_initialize, scanner_free, scanner_last_string_free)
5304 (gram_out, gram_lineno, YY_DECL_): Move to...
5305 * src/scan-gram.h: this new file.
5306 (YY_DECL): Rename as...
5308 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
5309 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
5310 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
5311 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
5312 Move these declarations, and...
5313 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
5315 * src/flex-scanner.h: this new file.
5316 * src/scan-gram.l (rule_length, rule_length_overflow)
5317 (increment_rule_length): Remove.
5318 (last_braced_code_loc): Rename as...
5319 (gram_last_braced_code_loc): this.
5320 Adjust to the changes of the parser.
5321 Move all the handling of $ and @ into...
5322 * src/scan-code.l: here.
5323 * src/scan-gram.l (handle_dollar, handle_at): Remove.
5324 (handle_action_dollar, handle_action_at): Move to...
5325 * src/scan-code.l: here.

5336 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5338 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5339 Use Akim's wording from
5340 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
5342 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5344 Between Bison releases, manually append `+' to the previous Bison
5345 release number, and use that as a signal to automatically print the
5346 ChangeLog's CVS Id keyword from --version. Discussed starting at
5347 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
5348 * ChangeLog: Add Id header.
5349 * configure.ac (AC_INIT): Append `+' to `2.3'.
5350 * src/.cvsignore: Add revision.c.
5351 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
5352 (BUILT_SOURCES): Add revision.c.
5353 (revision.c): New target rule. This file defines a new global variable
5354 named revision. It initializes it with either the Id from ChangeLog
5355 or, if VERSION doesn't contain `+', with the empty string.
5356 * src/getargs.c (version): Print the value of revision.
5357 * src/revision.h: Extern revision.
5359 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5361 * NEWS: Version 2.3.
5362 * configure.ac (AC_INIT): Likewise.
5364 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5366 * data/glr.c (YYRECOVERING): Define to be a function-like macro
5367 with no arguments, not as an object-like macro. This is for
5368 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
5369 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
5370 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
5373 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
5375 * src/getargs.c (usage): Back out yesterday's modification of the
5376 --help output so that we don't have to wait for translation before
5379 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5381 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
5382 Problem reported by Akim Demaille.
5384 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
5386 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5388 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5390 * data/yacc.c (yy_reduce_print): Omit trailing white space in
5391 generated source code. Problem reported by Frans Englich in
5392 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
5394 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
5396 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
5397 shell, not within 'make', so that 'make' by an ordinary builder
5398 (using GNU make) does not worry about configuring gzip. This also
5399 works around a bug reported independently by Keith Thompson and by
5400 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
5401 stderr rather than stdout, messing up the build logs.
5403 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5405 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
5406 to make sure that YYID will never be unused. This fixes a 'make
5407 maintainer-check' failure caused by the recent changes to the 'Trivial
5408 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
5410 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
5412 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5414 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
5415 state before an empty RHS is always resolved here. Only the location
5416 of that state is guaranteed to be resolved, and that's enough. This
5417 fixes the remaining bug reported by Derek M. Jones in
5418 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5419 * tests/glr-regression.at (Uninitialized location when reporting
5420 ambiguity): Test the above case.
5421 Also, the embedded comments in this test case claim it checks the case
5422 of an empty RHS that has inherited the initial location. However, the
5423 corresponding LHS was already resolved, so yyresolveLocations didn't
5424 actually have reason to modify it. Fix this by forcing
5425 nondeterministic operation at the beginning of the parse.
5427 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5429 * data/c.m4 (b4_yy_symbol_print_generate):
5430 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
5431 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
5432 of the bugs reported today by Derek M Jones in
5433 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5434 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
5435 defined to be a type name without parens or brackets.
5436 (Location Type): Similarly for YYLTYPE.
5437 * tests/regression.at (Trivial grammars): Put in a test for this
5438 bug that will be caught by 'make maintainer-check' (though not,
5439 alas, by 'make check' unless your compiler is picky).
5441 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5443 * NEWS: Version 2.2.

5446 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
5448 * data/glr.c (yyreportTree): Make room in yystates for the state
5449 preceding the RHS. This fixes the segmentation fault reported by Derek
5451 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
5452 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
5453 to the user. Reported for yyreportTree by Derek M. Jones later in the
5455 * THANKS: Add Derek M. Jones.
5456 Update my email address.
5457 Fix typo in Steve Murphy's name.
5459 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5461 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
5462 checking against YYLAST that caused the parser to miss a potential
5463 alternative in its diagnostic.
5464 Problem reported by Maria Jose Moron Fernandez in
5465 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
5466 * data/lalr1.cc (yysyntax_error_): Likewise.
5467 * data/yacc.c (yysyntax_error): Likewise.
5468 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
5469 tokens, in case we run into an older C compiler.
5470 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
5471 Use them to check for the off-by-one error fixed above.
5473 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
5474 YYSIZE_T, not size_t.
5475 * tests/regression.at (Trivial grammars): New test, to catch
5476 the error fixed by the above patch.
5478 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5480 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
5482 Reported by Steve Murphy.
5484 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5486 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
5487 * data/glr.cc: b4_location_flag is now b4_locations_flag.
5489 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5491 Implement --trace=m4.
5492 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
5493 * src/output.c (output_skeleton): When set, pass -dV to m4.
5495 Factor the handling of flags in m4.
5496 * src/output.c (prepare): Rename the muscle names debug, defines,
5497 error_verbose to debug_flag, defines_flag, error_verbose_flag.
5498 * data/c.m4: Adjust.
5499 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
5500 Use b4_define_flag_if to define other b4_FLAG_if macros.
5501 (b4_location_if): As a consequence, rename as...
5502 (b4_locations_if): this, for consistency.
5503 Adjust all the skeletons.
5505 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5507 * etc/bench.pm: Shorten bench names.
5509 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5511 * src/output.h, src/output.c (error_verbose): Move to...
5512 * src/getargs.h, src/getargs.c: here.
5514 Adjust dependencies.
5516 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5518 * data/c.m4 (b4_copyright): Put the special exception for Bison
5519 skeletons here, so we don't have to put it in each skeleton. All
5520 uses changed. Suggested by Akim Demaille. Also, wrap the
5521 copyright notice, in case it is longer than 80 columns. Replace
5522 comma by newline after title.
5524 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5526 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
5527 incompatibility, not a bug. Mention that it wasn't fixed as of
5530 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
5532 * examples/extexi: Enforce the precedence of concatenation over
5534 Reported by Tommy Nordgren.
5536 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
5538 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
5539 with the member "token".
5540 Reported by Martin Nylin.
5542 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
5544 * data/glr.c: Switch to Bison 2.2 special-exception language in
5545 the copyright notice. Use more-regular format for titles and

5553 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
5555 * data/glr.cc: Remove dead code.
5557 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5559 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
5560 that variable and the line breaks the bootstrap. Problem reported
5561 by Juan M. Guerrero.
5563 2006-04-24 Akim Demaille <akim@lrde.epita.fr>

5581 Problem reported by Bob Rossi.
5583 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
5585 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
5586 and didn't really work.
5587 For the index, use @ifnotinfo, not @iftex.
5588 Minor cleanups of spacing and terminology.
5590 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
5592 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
5593 of AT_NAME_PREFIX when %name-prefix is not used.
5595 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
5597 Apply --prefix to C++ skeletons too: they change the namespace.
5598 The test suite already exercize these cases.
5599 * data/c++.m4 (b4_namespace): New.
5600 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
5601 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
5602 * data/yacc.c, data/glr.c: Remove a useless `[]'.
5603 * doc/bison.texinfo: Document it.
5604 (Option Cross Key): Use @multitable in all formats. It looks
5605 nicer, even in TeX outputs.
5606 (Rules): Use the same code whatever the output type is.
5607 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
5608 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
5609 * tests/calc.at: Use it, instead of hard coding `yy'.

5615 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
5617 * doc/FAQ: Remove, merged into...
5618 * doc/bison.texinfo (FAQ): this.

5626 * doc/bison.texinfo (Calc++ Scanner): Use it.
5628 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
5630 Fix two nits reported by twlevo, plus one more that I discovered.
5632 * src/assoc.h (assoc_to_string): Give a name to the arg, as
5633 this is the usual Bison style.
5634 * src/location.h (location_print): Likewise.
5636 * src/reader.h (token_name): Likewise.
5638 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
5640 Fix some nits reported by twlevo.
5641 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
5642 and "POSIX". Use more-modern syntax for URLs. Mention C++
5643 and ask for Java. Don't hardwire OS version numbers. Add
5645 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
5646 * src/conflicts.c (solved_conflicts_obstack): Now static.
5648 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
5650 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
5651 page. Say "you can use it" not "you may use it" as on the web page;
5652 we're describing capabilities not granting permission.
5654 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
5656 * data/glr.c (yyresolveLocations): Rename local variables to avoid
5657 shadowing warnings. Use usual patter for iterating through RHS.
5658 * tests/glr-regression.at
5659 (Uninitialized location when reporting ambiguity):
5660 Modify yylex so that it uses its argument, rather than trying
5661 to rely on ARGSUSED (which doesn't work for gcc with warnings).
5662 const char -> char const.
5664 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
5665 Don't use tabs inside commands; it messes up 'ps'.
5666 Problem reported by twlevo.
5668 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
5670 * tests/glr-regression.at (Uninitialized location when reporting
5671 ambiguity): New test case.
5672 * data/glr.c (yyresolveLocations): New function, which uses
5674 (yyresolveValue): Invoke yyresolveLocations before reporting an
5676 * doc/bison.texinfo (Default Action for Locations): Note
5677 YYLLOC_DEFAULT's usage for ambiguity locations.
5678 (GLR Semantic Actions): Cross-reference those notes.
5680 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
5682 * tests/glr-regression.at (Leaked semantic values when reporting
5683 ambiguity): Remove unnecessary union and type declarations.
5684 (Leaked lookahead after nondeterministic parse syntax error): New test
5686 * data/glr.c (yyparse): Check for zero stacks remaining before
5687 attempting to shift the lookahead so that you don't lose it.
5689 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5691 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
5692 * tests/glr-regression.at (Leaked semantic values when reporting
5693 ambiguity): New test case.
5694 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
5695 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
5696 now unnecessary yystackp parameter.
5697 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
5698 destructors can be called.
5700 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
5701 in existing testcases.
5703 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5705 Don't leak semantic values for parent RHS when a user action cuts the
5706 parser, and clean up related code a bit.
5707 * tests/glr-regression.at (Leaked merged semantic value if user action
5708 cuts parse): Rename to...
5709 (Leaked semantic values if user action cuts parse): ... this. Add check
5710 for leaked parent RHS values.
5711 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
5712 between an unresolved state (non-empty chain of semantic options) and
5713 an incomplete one (signaled by an empty chain).
5714 (yyresolveStates): Document the interface. Move all manipulation of a
5715 successfully or unsuccessfully resolved yyGLRState to...
5716 (yyresolveValue): ... here so that yyresolveValue always leaves a
5717 yyGLRState with consistent data and thus is easier to understand.
5718 Remove the yyvalp and yylocp parameters since they are always just
5719 taken from the yys parameter. When reporting a discarded merged value
5720 in debugging output, note that it is incompletely merged. Document the
5722 (yyresolveAction): If resolving any of the RHS states fails, destroy
5723 them all rather than leaking them. Thus, as long as user actions are
5724 written to clean up the RHS correctly, yyresolveAction always cleans up
5725 the RHS of a semantic option. Document the interface.
5727 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
5729 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
5730 led to a segmentation fault in GNU Pascal. Problem reported
5733 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
5735 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
5736 mid-rule action inside a nonterminal symbol in order to declare a
5737 destructor for its semantic value.

5744 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
5745 defined free))]: Include <stdlib.h> rather than rolling our own
5746 declarations of malloc and free, to avoid problems with
5747 incompatible declarations (using 'throw') C++'s stdlib.h. This
5748 should fix Debian bug 340012

5789 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
5791 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
5792 nodist_PROGRAMS, since we don't need to actually compile the
5793 example if we're just doing a plain 'make'. This avoids bothering
5794 the installer unnecessarily about problems due to weird C++

5803 not portable, according to Posix and the C standard, and it does
5804 not work with Sun C 5.7, where previous #line directives affect

5824 that '#include <string>' works.
5826 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
5827 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
5828 "warning: sorry: semantics of inline function static data `const
5829 unsigned char translate_table[262]' are wrong (you'll wind up with

5835 random system header somewhere that includes the equivalent of

5844 During deterministic GLR operation, user actions should be able to
5845 influence the parse by changing yychar. To make this easier to fix and
5846 to make glr.c easier to evolve in general, don't maintain yytoken in
5847 parallel with yychar; just compute yytoken when needed.
5848 * tests/glr-regression.at (Incorrect lookahead during deterministic
5849 GLR): Check that setting yychar in a user action has the intended

5854 yychar rather than *yytokenp to determine the current lookahead.
5855 Compute yytoken locally when needed.

5874 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
5875 got from <http://bro-ids.org/download.html>. The bug is that
5876 when two actions appeared in succession, the second one was
5877 scanned before the first one was added to the grammar rule
5878 as a midrule action. Bison then output the incorrect warning
5879 "parse.y:905.17-906.36: warning: unused value: $3".
5880 * src/parse-gram.y (BRACED_CODE, action): These are no longer
5881 associated with a value.
5882 (rhs): Don't invoke grammar_current_rule_action_append.
5883 (action): Invoke it here instead.
5884 * src/reader.c (grammar_midrule_action): Now extern.
5885 (grammar_current_rule_action_append): Don't invoke
5886 grammar_midrule_action; that is now the scanner's job.
5887 * src/reader.h (last_string, last_braced_code_loc):
5888 (grammar_midrule_action): New decls.
5889 * src/scan-gram.l (last_string): Now extern, sigh.
5890 (last_braced_code_loc): New extern variable.

5892 rule already has an action.

5894 * tests/input.at (AT_CHECK_UNUSED_VALUES):
5895 Add some tests to check that the above changes fixed the bug.

5900 All used changed. Check whether the symbol has a destructor,
5901 not whether it is typed.

5920 user can override the types.
5921 (short): #undef, to work around a bug in Pike 7.0.
5922 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
5923 (union yyalloc.yyss): Use yytype_int16 rather than short.
5925 (yysigned_char): Remove.

6141 in the yychar entry.
6142 In the yychar entry, remove mention of the local yychar case (pure
6143 parser) since this is irrelevant information when writing semantic
6144 actions and since it's already discussed in `Table of Symbols' where
6145 yychar is otherwise described as an external variable.
6146 In the yychar entry, don't call it the `current' look-ahead since it
6147 isn't when semantic actions are deferred.
6148 In the yychar and yyclearin entries, add note about deferred semantic
6150 Add yylloc and yylval entries discussing look-ahead usage.
6151 (Look-Ahead Tokens): When discussing yychar, don't call it the

6172 appropriately during nondeterministic operation.
6173 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
6174 members to store the current lookahead to be used by the deferred
6176 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
6177 from which the RHS is taken. Set the lookahead members of the new
6178 yySemanticOption according to the lookahead status for stack yyk.

6180 yyaddDeferredAction.
6181 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

6192 (Incorrect lookahead during nondeterministic GLR): New test case.
6194 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

6206 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
6208 * data/glr.c (yyresolveValue): When merging semantic options, if at
6209 least one user action succeeds but a later one cuts the parse, then
6210 destroy the semantic value before returning rather than leaking it.
6211 (yyresolveStates): If a user action cuts the parse and thus
6212 yyresolveValue fails, ignore the (unset) semantic value rather than
6213 corrupting the yyGLRState, and empty the semantic options list since
6214 the user actions should have called all necessary destructors.
6215 Simplify code with YYCHK.
6216 * tests/glr-regression.at (Corrupted semantic options if user action
6217 cuts parse): New test case.
6218 (Undesirable destructors if user action cuts parse): New test case.

6415 Undo 2005-12-01 tentative license wording change. The wording is
6416 still being reviewed by the lawyers, and we don't want to wait for
6417 them before publishing a test release. For now, revert to the

6441 for semantic values was leaked instead.
6443 2005-12-21 Joel E. Denny <address@hidden>
6445 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.

6465 destroy the RHS symbols of a rule.
6466 * data/yacc.c (yylen): Initialize to 0.

6484 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
6485 * djgpp/config.sed: Replace every occurence of the file name
6486 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

6516 sed out the final state number.
6518 Work around portability problem on Solaris 10: flex-generated
6519 files include <stdio.h> before <config.h>, which messes up
6520 because the latter defines __EXTENSIONS__. Address the problem
6521 by creating two new little files that include <config.h> first,
6522 then include the flex-generated files. Rewrite everyone else
6523 to include <config.h> first, as well.
6524 * lib/timevar.c: Always include "config.h".

6566 definition if 'lint' is defined.
6567 (YYID): New macro (or function, if lint).
6568 All uses of /*CONSTCOND*/0 replaced by YYID(0).
6569 * data/yacc.c: Likewise.
6570 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
6571 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
6572 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
6574 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
6575 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
6576 Use YYID(0) rather than 0, for lint.
6577 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.

6598 * NEWS: Document the following change.
6599 * data/yacc.c: Say "parser skeleton" rather than "file", since
6600 it's no longer just a file.
6601 * data/glr.c: Grant a special exception for C GLR parsers, that
6602 reads like the already-existing exception for C LALR(1) parsers.

6604 * data/lalr1.cc: Likewise.
6605 * data/location.cc: Likewise.

6867 but some people prefer the printf style.
6868 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
6869 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.
6870 All uses replaced by YYFPRINTF and YYDPRINTF.

6890 unused-variable warnings.
6892 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

6896 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
6898 Use unlocked I/O for a minor performance improvement on hosts like
6899 GNU/Linux and Solaris that support unlocked I/O. The basic idea
6900 is to use the gnlib unlocked-io module, and to prefer putc and
6901 puts to printf when either will work (since the latter doesn't
6902 come in an unlocked flavor).
6903 * bootstrap (gnulib_modules): Add unlocked-io.

6922 * src/system.h: Include unlocked-io.h rather than stdio.h.
6924 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as

6974 to allow support for non-posix systems. This is a no-op function
6977 * src/output.c (output_skeleton): Use end_of_output_subpipe() to

7017 (parser::semantic_value): Now a full definition instead of an
7018 indirection to YYSTYPE.

7062 local variables whose names begin with 'yy'.
7063 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
7064 Trivial changes from Joel E. Denny.
7066 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
7068 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
7069 don't use alloca any more.
7071 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
7072 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
7073 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.

7084 This works a bit better with glibc, if user code has already included
7086 * doc/bison.texinfo (Bison Parser): Document that users can't
7087 arbitrarily use malloc and free for other purposes. Document
7088 that <alloca.h> and <malloc.h> might be included.

7102 (YYSTACK_ALLOC_MAXIMUM): Use it.
7103 (yysyntax_error): New function.
7104 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
7105 multiple syntax errors are reported, and alloca is being used.
7106 Instead, reallocate buffers twice as big each time, so that
7107 we waste at most half the allocated memory. Start with a small
7108 (128-byte) buffer that will suffice in most cases anyway.
7109 Use yysyntax_error to do most of the work.
7111 * doc/bison.texinfo (Error Reporting, Table of Symbols):
7112 yynerrs is the number of errors reported, not the number of

7121 2005-09-19 Akim Demaille <akim@epita.fr>
7123 Remove the traits, failed experiment.
7124 It never proved useful, and anyway because of the current
7125 definition, it was not possible to have several specialization of
7126 this traits, making it useless.
7127 * data/lalr1.cc (yy:traits): Remove.
7128 Inline its definitions in the parser class.
7130 2005-09-19 Akim Demaille <akim@epita.fr>

7153 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
7154 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
7155 is not defined. This is an awful hack, but it's enough for now.
7156 All callers changed.
7157 * tests/glr-regression-at (make_value): Args are const pointers now,
7158 to avoid GCC warning.
7159 (Duplicated user destructor for lookahead): New test. Currently
7160 skipped. It fails on my host but I'm not sure it'll always fail.
7162 2005-09-16 Akim Demaille <akim@epita.fr>
7164 * src/symtab.h (struct symbol): Declare the printer and destructor
7165 as const, to avoid accidental calls to free.

7180 2005-09-16 Akim Demaille <akim@epita.fr>
7182 * data/lalr1.cc (yylex_): Remove, inline its code.
7183 (yyreport_syntax_error_): Remove, replaced by...
7184 (yysyntax_error_): this which returns a string and leaves to the
7185 caller the call to the users' error function.
7186 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
7187 Move from members of the parser object...
7188 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):

7212 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
7213 do anything if $@ exists. This reverts part of the 2005-07-07
7216 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
7218 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
7219 contains obsolete information and isn't worth distributing as a
7220 separate file anyway.
7221 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
7222 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

7229 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
7230 Suggested by twlevo@xs4all.nl.
7232 * data/glr.c (YYCHK1): Do not assume YYE is in range.

7234 Problem reported by twlevo@xs4all.nl.
7236 * doc/bison.texinfo: Don't use "filename", as per GNU coding
7237 standards. Use "file name" or "file" or "name", depending on
7239 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
7240 not to hack/foo.tab.c.
7241 (Calc++ Top Level): 2nd arg of main is not const.
7242 * data/glr.c: b4_filename -> b4_file_name.

7324 All callers changed to avoid the newline.
7325 (yyprocessOneStack): Output two lines rather than one, to accommodate
7326 the above change. This changes the debug output format slightly.

7344 "make check" doesn't finish with "All 1 tests passed".
7346 * tests/regression.at (Token definitions): Don't rely on
7347 AT_PARSER_CHECK for data that contains backslashes. It currently
7348 uses 'echo', and 'echo' isn't portable if its argument contains
7349 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
7350 that the byte '\0xff' is not printable in the C locale; it is,
7351 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
7352 not printable, so use '\0x81' to test.
7354 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
7355 version of GCC, since the macro is used with non-GCC compilers.
7357 Fix core dump reported by Pablo De Napoli in
7358 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
7359 * tests/regression.at (Invalid inputs with {}): New test.
7360 * src/parse-gram.y (token_name): Translate type before using
7363 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
7364 the user's name space. All uses changed to __attribute__
7366 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
7367 Add __attribute__ ((__noreturn__)).
7369 * etc/clcommit: Remove. We weren't using it, and it failed
7370 "make maintainer-distcheck".
7371 * Makefile.maint: Merge from coreutils.
7372 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
7373 (syntax-check-rules): Change list of rules as described below.
7374 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

7384 Use grep -n, to make it easier to find violations.
7385 Use CVS_LIST and CVS_LIST_EXCEPT.
7386 (header_regexp, h_re): Remove.
7388 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
7389 (my-distcheck): Use more-modern GCC flags.
7390 (signatures, %.asc): Remove.
7391 (rel-files, announcement): Remove signatures.
7392 Restore old updating code, even though we don't use it, so
7393 that we're the same as coreutils.
7394 (alpha, beta, major): Depend on news-date-check.
7395 Make the upload commands.
7397 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
7398 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
7399 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
7400 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
7401 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
7402 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
7403 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
7404 * tests/sets.at: Likewise.
7406 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
7407 we comment out the Autoconf version number.
7408 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
7409 it's error-prone and "make maintainer-distcheck" rejects it.
7411 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
7412 Indent calls to "error" to pacify "make maintainer-distcheck",
7413 when the calls are not intended to be translated.
7414 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
7416 * src/Makefile.am (DEFS): Use +=, to pacify
7417 "make maintainer-distcheck".
7418 (bison_SOURCES): Add scan-skel.h.
7419 (sc_tight_scope): New rule, from coreutils.
7421 * src/files.c (src_extension, header_extension):
7422 Now static, not extern.
7423 * src/getargs.c (short_options): Likewise.
7424 * src/muscle_tab.c (muscle_table): Likewise.
7425 * src/parse-gram.y (current_class, current_type, current_prec):
7427 * src/reader.c (grammar_end, previous_rule_end): Likewise.
7428 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
7429 * src/main.c (main): Cast bindtextdomain and textdomain calls to
7430 void, to avoid warning when NLS is disabled.
7431 * src/output.c: Include scan-skel.h.
7432 (scan_skel): Remove decl, since scan-skel.h does this.
7434 Indent calls to "error" to pacify "make maintainer-distcheck".
7435 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
7436 * src/reader.h (gram_end, gram_lineno): New decls to pacify
7437 "make maintainer-distcheck".
7438 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
7439 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
7440 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
7441 (skel_lex_destroy, scan_skel): Move these decls to...
7442 * src/scan-skel.h: New file.
7443 * src/uniqstr.c (uniqstr_assert):
7444 Indent calls to "error" to pacify "make maintainer-distcheck".
7446 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
7449 * tests/torture.at: Revamp to avoid misuse of atoi that
7450 "make maintainer-distcheck" complained about.
7452 * examples/extexi (message): Don't print a message more than once,
7453 and omit line-number decoration that makes Emacs compile think
7454 that informative messages are worth worrying about.
7456 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
7458 * configure.ac: Update version number.
7460 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
7462 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
7463 autogenerated by the maintainer.
7464 * examples/calc++/.cvsignore: Add *.yy.
7466 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
7467 * lib/bitset_stats.c (bitset_stats_init): Likewise.
7468 * lib/bitsetv.c (bitsetv_alloc): Likewise.
7470 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
7472 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
7473 from maintainer-distcheck about casting the argument of 'free'.
7475 * NEWS: Mention recent yytname changes.
7476 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
7478 * bootstrap: For translations that have not yet been upgraded to
7479 the new runtime-po domain, prime the pump by extracting the
7480 relevant strings from the obsolete translations. This code can be
7481 removed once the bison-runtime domain has been translated by each
7484 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
7485 now that token names are already quoted.
7487 Fix problem reported by Anthony Heading.
7488 * data/glr.c (YYTOKEN_TABLE): New macro.
7489 (yytname): Define if YYTOKEN_TABLE.
7490 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
7491 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
7492 (YYERROR_VERBOSE): Define the same way the other skeletons do.
7493 * src/output.c (prepare_symbols): Output token_table_flag.
7495 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
7497 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
7498 again if the first call fails.
7500 * data/glr.c (yytnamerr): New function.
7501 (yyreportSyntaxError): Use it to dequote most string literals.
7502 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
7503 with other skeletons. All uses changed.
7504 (yytnameerr_): New function.
7505 (yyreport_syntax_error): Use it to dequote most string literals.
7506 * data/yacc.c (yytnamerr): New function.
7507 (yyerrlab): Use it to decode most string literals.
7508 * doc/bison.texinfo (Decl Summary, Calling Convention):
7509 Clarify quoting convention of yytname.
7510 * src/output.c (prepare_symbols): Quote all names. This undoes
7511 the 2005-04-17 change, which is now accomplished (mostly) via
7512 changes in the parsers as described above.
7513 * tests/regression.at (Token definitions, Web2c Actions):
7514 Undo most 2005-04-17 change here, too.
7516 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
7518 Fix more problems reported by twlevo@xs4all.nl.
7519 * tests/cxx-type.at: Don't pipe output of ./types through sed to
7520 remove trailing spaces. This loses the exit status of ./types,
7521 and isn't needed since ./types shouldn't be emitting trailing
7523 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
7524 as the stack isn't valid in that case.
7526 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
7527 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
7528 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
7529 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
7531 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
7532 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
7533 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
7536 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
7537 overly-picky compilers that reject 'char *foo = "bar";'.
7539 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
7540 to FILE * parameter, not to stderr. This fixes a typo introduced
7541 in the 2005-07-12 change.
7543 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
7544 warnings from GCC 4.
7546 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
7547 (yyglrShiftDefer, yysplitStack):
7548 Remove unused parameters b4_pure_formals. All uses changed.
7549 (yyglrShift): Remove unused parameters b4_user_formals.
7551 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
7553 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
7555 Destructor cleanups and regularization among the three skeletons.
7556 * NEWS: Document the behavior changes.
7557 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
7558 stack before failing, as the cleanup code will do it for us now.
7559 * data/lalr1.cc (yyerrlab): Likewise.
7560 * data/glr.c (yyparse): Pop everything off the stack before
7561 freeing it, so that destructors get called properly.
7562 * data/lalr1.cc (yyreturn): Likewise.
7563 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
7564 This is more consistent.
7565 * doc/bison.texinfo (Destructor Decl): Mention more reasons
7566 why destructors might be called. 1.875 -> 2.1.
7567 (Destructor Decl, Decl Summary, Table of Symbols):
7568 Some English-language cleanups for %destructor.
7569 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
7570 Add output line for destructor of start symbol.
7571 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
7572 because of that same extra output line.
7574 * NEWS: Document minor wording changes in diagnostics of
7575 Bison-generated parsers.
7576 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
7577 Remove unused formals. All uses changed.
7578 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
7579 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
7580 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
7581 Rename yyoverflowab to yyexhaustedlab.
7582 When memory exhaustion occurs during syntax-error reporting,
7583 report it separately rather than in a single diagnostic; this
7585 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
7586 (Memory Exhausted): Renamed from Parser Stack Overflow.
7587 Revamp wording slightly to prefer "memory exhaustion".
7588 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
7590 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
7592 Add i18n support to the GLR skeleton. Partially fix the C++
7593 skeleton; a C++ expert needs to finish this. Remove debugging
7594 msgids; there's little point to having them translated, since they
7595 can be understood only by someone who can read the
7596 (English-language) source code.
7598 Generate runtime-po/bison-runtime.pot automatically, so that we
7599 don't have to worry about garbage getting in that file. We'll
7600 make sure after the next official release that old msgids don't
7602 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
7604 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
7606 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
7607 Fix typos in explanations of the runtime file.
7608 * bootstrap: Change gettext keyword from YYI18N to YY_.
7609 Use standard Makefile.in.in in runtime-po, since we'll arrange
7610 for backward-compatible bison-runtime.po files in a different way.
7611 * data/glr.c (YY_): New macro, from yacc.c.
7612 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
7613 Translate messages intended for users.
7614 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
7615 the wording in the other skeletons. We don't know that the memory
7617 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
7618 Use same method that yacc.c uses.
7619 Don't translate debugging messages.
7620 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
7621 it doesn't work (yet), and requires C++ expertise to fix.
7622 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
7623 Move defn to a more logical place, to be consistent with other
7625 Don't translate debugging messages.
7626 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
7627 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
7628 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
7629 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
7631 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
7632 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
7634 * tests/glr-regression.at (Badly Collapsed GLR States):
7636 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
7637 yylex should return 0 at EOF rather than aborting.
7639 Improve tests for stack overflow in GLR parser.
7640 Problem reported by twlevo@xs4all.nl.
7641 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
7643 (yyStackOverflow): Just longjmp, but with value 2 so that caller
7644 can handle the problem.
7645 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
7646 (yyparse): New local variable yyresult to record the result.
7647 Use result of setjmp to set it, rather than storing itinto
7649 (yyDone): Remove label.
7650 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
7651 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
7652 if YYABORT is used).
7653 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
7654 yyparse status; put status > 1 into diagnostic.
7655 Check that status==2 works.
7656 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
7657 Use exit status 3 for failure to open (which shouldn't happen).
7659 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
7661 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
7662 1 on syntax error; just let yyparse do its thing.
7663 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
7664 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
7665 (Exploding the Stack Size with Alloca):
7666 (Exploding the Stack Size with Malloc):
7667 Expect exit status 2, not 1, since the parser is supposed to blow
7668 its stack. Problem reported by twlevo@xs4all.nl.
7670 * data/glr.c (yyparse): Don't assume that the initial calls
7671 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
7672 Print a stack-overflow message and fail instead.
7673 Initialize the line-number information before creating the stack,
7674 so that the stack-overflow message can report line zero safely.
7676 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
7678 Fix problems reported by twlevo@xs4all.nl.
7679 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
7680 (yyuserMerge): Provide a default case if b4_mergers is empty.
7681 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
7682 * tests/glr-regression.at
7683 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
7684 Add casts to pacify C++ compilers.
7685 * tests/glr-regression.at (Improper merging of GLR delayed action
7686 sets): Declare yylex before using it.
7687 * tests/Makefile.am (maintainer-check-g++): Fix a stray
7688 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
7689 test for valgrind; valgrind is independent of g++.
7690 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
7691 for compatibility with POSIX 1003.1-2001 (if running coreutils).
7692 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
7693 Use a destructor, so that we can expand the stack. Change
7694 YYSTYPE to char * so that we can free it. Cast result of malloc.
7696 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
7698 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
7699 a valgrind failure. Problem reported by twlevo@xs4all.nl.
7701 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
7703 * PACKAGING: New file, suggested by Bruno Haible and taken from
7704 similar wording in gettext's PACKAGING file.
7705 * NEWS: Mention PACKAGING.
7706 * Makefile.am (EXTRA_DIST): Add PACKAGING.

7710 * NEWS: Document recent i18n improvements.
7711 * bootstrap: Get runtime translations into runtime-po.
7712 Create runtime-po files automatically, if possible.
7713 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
7714 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
7715 does not infringe on the user's name space.
7716 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
7717 * doc/bison.texinfo (Internationalization): Revamp the English
7718 and Texinfo syntax a bit, to try to make it clearer.
7719 (Bison Options, Option Cross Key): Mention --print-localedir.
7720 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
7721 YYENABLE_NLS. Quote a bit more.
7722 * runtime-po/.cvsignore: New file.

7731 * runtime-po/Makevars: Likewise.
7732 * runtime-po/LINGUAS: Likewise.
7733 * runtime-po/de.po: Likewise; we will rely on the translation project
7734 to maintain this, so "bootstrap" should get it.
7735 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
7737 * src/main.c (main): Bind the bison-runtime domain, too.
7739 2005-07-12 Bruno Haible <bruno@clisp.org>
7741 * data/yacc.c: Include <libintl.h> when NLS is enabled.
7742 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
7743 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
7744 * runtime-po: New directory.
7745 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
7746 $(DOMAIN).pot-update rule, so that old messages are never dropped.
7747 * runtime-po/Rules-quot: New file, copied from po/.
7748 * runtime-po/quot.sed: Likewise.
7749 * runtime-po/boldquot.sed: Likewise.

7760 * Makefile.am (SUBDIRS): Add runtime-po.
7761 (aclocaldir, aclocal_DATA): New variables.
7762 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
7764 * src/getargs.c (usage): Document --print-localedir option.
7765 (PRINT_LOCALEDIR_OPTION): New enum item.
7766 (long_options): Add --print-localedir option.
7767 (getargs): Handle --print-localedir option.
7768 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
7769 (Internationalization): New section.
7771 2005-07-12 Akim Demaille <akim@epita.fr>
7773 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
7774 for consistency with the rest of the code.
7775 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
7778 2005-07-12 Akim Demaille <akim@epita.fr>
7780 * src/parse-gram.y: Use %printer instead of YYPRINT.
7782 2005-07-12 Akim Demaille <akim@epita.fr>
7784 * src/symtab.h, src/symtab.c (symbol_print): New.
7785 * src/symlist.h, src/symlist.c (symbol_list_print): New.
7786 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
7788 2005-07-12 Akim Demaille <akim@epita.fr>
7790 * data/glr.c (b4_syncline): Fix (swap) the definitions of
7791 b4_at_dollar and b4_dollar_dollar.
7793 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
7795 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
7796 and Pennello's paper.
7798 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
7800 * data/yacc.c (yyparse): Undo previous patch. Instead,
7801 set yylsp[0] and yyvsp[0] only if the initial action
7802 sets yylloc and yylval, respectively.
7804 * data/yacc.c (yyparse): In the initial action, set
7805 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
7806 This avoids the use of undefined variables if the initial
7807 action does not set yylloc and/or yylval.
7809 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7811 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
7812 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
7813 Remove from CVS. These files are automatically generated.
7814 * examples/extexi: Clarify that this file is now part of Bison,
7815 not GNU M4, and that it works with any POSIX-compatible Awk.
7816 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
7817 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
7818 so that we also get calc++-parser.yy. Geneate it.
7819 Use $(AWK), not gawk, since any conforming Awk will do.
7820 Put comment before action, since older 'make' can't handle comment
7822 $(BUILT_SOURCES): List all built sources, not just some of them.
7823 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
7824 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
7825 $($(calc_sources_generated)): Remove unnecessary test for existence
7826 of target. (This had a shell syntax error anyway; a stray "x".)
7827 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
7829 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
7831 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
7832 implied by the other modules.
7834 2005-07-06 Akim Demaille <akim@epita.fr>
7836 Bind examples/calc++ to the package.
7837 * examples/calc++/Makefile: Remove, replaced by...

7839 * examples/calc++/test: Remove input.
7840 * examples/calc++/compile: Remove.
7841 * examples/Makefile.am: New.
7842 * configure.ac, Makefile.am: Adjust.
7843 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
7845 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
7847 * data/glr.c (yyFail): Drastically simplify; since the format argument
7848 never had any % directives, we can simply pass it to yyerror.
7849 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
7850 be modified later, as that is the usual style in glr.c.
7851 Problems reported by Paul Hilfinger.
7853 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
7854 and size overflow errors.
7855 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
7856 in case the user prolog sets feature-test macros like _GNU_SOURCE.
7857 (YYSIZEMAX): New macro.
7858 (yystpcpy): New function, taken from yacc.c.
7859 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
7860 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
7861 so that we don't have to maintain their signatures.
7862 (yyFail): Check for buffer overflow, by using vsnprintf rather
7863 than vsprintf. Allocate a bigger buffer if possible.
7864 Report an error if buffer allocation fails.
7865 (yyStackOverflow): New function.
7866 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
7867 the initialization was successful. It might fail if storage was
7869 (yyexpandGLRStack): Add more checks for storage allocation failure.
7870 Use yyStackOverflow to report failures.
7871 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
7872 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
7873 Don't assume stack number fits in int.
7874 (yysplitStack): Check for storage allocation failure.
7875 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
7876 can print diagnostics on storage allocation failure. All callers
7878 (yyresolveValue): Use yybool for boolean.
7879 (yyreportSyntaxError): Check for size-calculation overflow.
7880 This code is taken from yacc.c.
7881 (yyparse): Check for storage allocation errors when allocating
7884 2005-07-05 Akim Demaille <akim@epita.fr>
7886 Extract calc++ from the documentation.
7887 * doc/bison.texinfo (Calc++): Add the extraction marks.
7888 * examples/extexi: New, from the aborted GNU Programming 2E.
7889 Separate the different paragraph of a file with empty lines.
7890 * examples/Makefile: Use it to extract the whole calc++ example.
7892 2005-06-24 Akim Demaille <akim@epita.fr>
7894 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
7897 2005-06-22 Akim Demaille <akim@epita.fr>
7899 * doc/bison.texinfo (C++ Language Interface): First stab.
7900 (C++ Parsers): Remove.
7902 2005-06-22 Akim Demaille <akim@epita.fr>
7904 * data/lalr1.cc (yylex_): Honor %lex-param.
7906 2005-06-22 Akim Demaille <akim@epita.fr>
7908 Start a set of simple examples.
7909 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
7910 * examples/calc++/calc++-driver.hh,
7911 * examples/calc++/calc++-parser.yy,
7912 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
7913 * examples/calc++/compile, examples/calc++/test: New.
7915 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
7917 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
7918 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
7919 which stems from the 2005-05-27 patch.
7921 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
7923 * data/glr.c: Modify treatment of unused parameters to permit use
7924 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
7926 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
7928 Fix infringement on user name space reported by Janos Zoltan Szabo.
7929 * data/yacc.c (yyparse): strlen -> yystrlen.
7931 2005-05-30 Akim Demaille <akim@epita.fr>
7933 * data/lalr1.cc (_): New.
7934 Translate the various messages.
7936 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
7938 Fix infringement on user name space reported by Bruno Haible.
7939 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
7940 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
7941 the user's name space.
7942 (alloca): Include <stdlib.h> to get it, if it's not built in.
7943 (YYMALLOC, YYFREE): Define only if needed.
7944 (malloc, free): Declare, but only if needed, as this infringes on
7945 the user name space.
7947 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7949 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
7950 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
7952 * lib/ebitset.c (min, max): Undef before defining.
7953 * lib/vbitset.c (min, max): Likewise.
7954 * lib/subpipe.c (create_subpipe): Save local variables in case
7955 vfork clobbers them.
7957 2005-05-24 Bruno Haible <bruno@clisp.org>
7959 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
7960 error message syntax used by gcc-4.0.
7962 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
7964 * README: Mention m4 1.4.3. Remove obsolete advice about
7965 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
7967 * bootstrap: Remove workaround for problem I encountered with
7968 gettext 0.14.1; it seems to be fixed now.
7970 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
7972 * NEWS: Version 2.0a.
7974 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
7975 the previous change.
7977 Various maintainer cleanups.
7978 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
7979 conftest*, for benefit of CVS commands run at the same time as
7980 "configure". Add build-aux, since "bootstrap" now creates it and
7982 * Makefile.cfg (move_if_change): Remove.
7983 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
7984 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

7989 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
7991 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
7992 this is now the recommended name.
7993 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
7994 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
7995 ylwrap. These files now go into build-aux.
7996 * config/move-if-change: Remove.
7997 * config/prev-version.txt: Bump from 1.75 to 2.0.
7999 * bootstrap: Add stdio-safer, unistd-safer modules.
8000 Remove m4/glibc2.m4 (introduced by latest gnulib, but
8002 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
8003 fopen-safer.c, stdio-safer.h, unistd-safer.h.
8004 * lib/subpipe.c: Include "unistd-safer.h".
8005 (create_subpipe): Make sure all the newly-created
8006 file descriptors are > 2, so that diagnostics don't
8007 get sent down them (which might cause Bison to hang, in theory).
8008 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
8009 * src/files.c (xfopen): Use fopen_safer, not fopen.
8011 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
8012 yesterday's yacc.c fix.
8014 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
8016 * data/glr.c, data/lalr1.cc: Update copyright date.
8018 Fix a destructor bug reported by Wolfgang Spraul in
8019 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
8020 * data/yacc.c (yyabortlab): Don't call destructor, and
8021 don't set yychar to EMPTY.
8022 (yyoverflowlab): Don't call destructor.
8023 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
8024 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
8025 since we no longer output the message "discarding lookahead token
8028 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8030 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
8031 fix a small glitch in debugging output.
8032 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
8033 after YY_SYMBOL_PRINT where needed.
8035 (struct yyGLRState): Add some comments.
8036 (struct yySemanticOption): Add some comments.
8037 (union yyGLRStackItem): Add comment.
8039 (yymergeOptionSets): Correct this to properly perform the union,
8040 avoiding infinite reported by Michael Rosien.

8084 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
8086 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
8087 Problem reported by Ralf Menzel.
8089 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8091 * tests/actions.at: Test that stack overflow invokes destructors.
8092 From Marcus Holland-Moritz.
8093 * data/yacc.c (yyerrlab): Move the code that destroys the stack
8095 (yyreturn): to here. That way, destructors are called properly
8096 even if the stack overflows, or the user calls YYACCEPT or
8097 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
8098 (yyoverflowlab): Destroy the lookahead.
8100 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
8102 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
8104 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
8106 * NEWS: Bison-generated C parsers no longer quote literal strings
8107 associated with tokens.
8108 * src/output.c (prepare_symbols): Don't escape strings,
8109 since users don't want to see C escapes.
8110 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
8112 * tests/input.at (Torturing the Scanner): Likewise.
8113 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
8115 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
8117 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
8118 the data size is known to be too small and we can't increase it.
8119 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
8121 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
8123 * src/parse-gram.y: Include quotearg.h.
8124 (string_as_id): Quote $1 before using it as a key, since the
8125 lexer no longer quotes it for us.
8126 (string_content): Don't strip quotes, since lexer no longer
8128 * src/scan-gram.l: Include quotearg.h.
8130 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
8131 a key, since the rest of the lexer doesn't quote it.
8132 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
8133 * tests/regression.at (Token definitions): Check for backslashes
8136 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
8137 (YYSIZE_T): Define to unsigned long int when using an older compiler.
8138 (yyparse): Revamp code to generate long syntax error message, to
8139 make it easier to translate, and to avoid problems with arithmetic
8140 overflow. Change "virtual memory" to "memory" in diagnostic, since
8141 we don't know whether the memory is virtual.
8143 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8145 * NEWS: Bison-generated C parsers now use the _ macro to
8147 * data/yacc.c (_) [!defined _]: New macro.
8148 All English strings wrapped inside this macro.
8149 * doc/bison.texinfo (Bison Parser): Document _.
8150 * po/POTFILES.in: Include src/parse-gram.c, since it now
8151 includes translateable strings that parse-gram.y doesn't.
8153 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
8155 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
8156 reverting the 2004-10-11 change to this function.
8157 (symbol_check_alias_consistency): Don't call symbol_type_set
8158 if the type name is already correct.
8159 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
8161 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
8163 * tests/regression.at (Token definitions): Don't use a token named
8164 c, as that generates a "#define c ..." that runs afoul of buggy
8165 stdlib.h that uses the identifier c as a member of struct
8166 drand48_data. Problem reported by Horst Wente.
8168 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
8170 * bootstrap: Change translation URL from
8171 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
8172 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
8173 redirection glitches. Problem reported by twlevo@xs4all.nl.
8175 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
8177 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
8178 after operands; POSIX says this isn't portable for the c99 command.
8180 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
8182 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
8183 immediately if a data overrun has occurred; this may help us track
8184 down what may be a spurious failure on MacOS.
8186 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
8188 Respond to problems reported by twlevo@xs4all.nl.
8190 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
8192 * src/vcg.h: Comment fix.
8193 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
8194 (G_CMAX): Change to -1 instead of INT_MAX.
8196 * data/yacc.c (yyparse): Omit spaces before #line.
8198 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
8200 * src/tables.c (state_number_to_vector_number): Put it inside an
8201 "#if 0", since it's not currently used. Problem reported by
8204 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
8206 * src/output.c (escaped_output): Renamed from
8207 escaped_file_name_output, since we now use it for symbol tags as
8208 well. All uses changed.
8209 (symbol_destructors_output, symbol_printers_output):
8210 Escape symbol tags too.
8211 Problem reported by Matyas Forstner in
8212 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
8214 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
8216 * src/output.c (user_actions_output, token_definitions_output,
8217 symbol_destructors_output, symbol_printers_output): Likewise.
8218 * src/reader.c (prologue_augment): Likewise.
8219 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
8221 * src/vcg.c (output_edge): Don't quote linestyle arg.
8222 Problem reported by twlevo@xs4all.nl.
8224 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
8226 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
8227 example, reported by Derek M Jones. Also, make the example even
8228 more outrageous, to better illustrate how bad the problem is.
8230 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
8232 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
8233 putsym. Typo reported by Sebastian Piping.
8235 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8237 * doc/bison.texinfo (Language and Grammar): some -> same
8238 (Epilogue): int he -> in the
8239 Typos reported by Sebastian Piping via Justin Pence.
8241 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8243 * tests/glr-regression.at (Improper handling of embedded actions
8244 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
8245 embedded actions and $-N in GLR parsers", work around an Autoconf bug
8246 with dollar signs in test names.
8247 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
8248 for a similar reason.
8250 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8252 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
8253 wants to redefine G_VIEW.
8255 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
8257 * src/vcg.c (get_view_str): Remove case for normal_view.
8258 Problem reported by twlevo@xs4all.nl.
8260 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
8262 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
8263 Problem reported by twlevo@xs4all.nl.
8265 * doc/bison.texinfo: Change @dircategory from "GNU programming
8266 tools" to "Software development". Requested by Richard Stallman
8269 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
8271 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
8272 Problem reported by twlevo@xs4all.nl.
8274 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8276 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
8277 keyword; it's not needed with modern compilers, and it doesn't
8278 affect correctness with older compilers. Suggested by
8281 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
8283 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
8284 gcc -Wswitch-default.
8285 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
8286 * data/yacc.c (yyparse): Likewise.
8288 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
8290 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
8291 already. Let config.h define any nonstandard values.
8293 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
8295 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
8296 for the benefit of slower hosts. Problem reported by
8299 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
8301 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
8302 being defined and not used.
8303 * data/lalr1.cc (yyparse): Likewise.
8304 Use "if (false)" rather than "if (0)".
8306 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
8308 * TODO: Mention that we should allow NUL bytes in tokens.
8310 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
8312 * src/scan-skel.l (<<EOF>>): Don't close standard output.
8313 Problem reported by Hans Aberg.
8315 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
8317 * src/getargs.c (version): Happy new year; update overall
8318 program copyright date from 2004 to 2005.
8320 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
8321 Problem reported by Hans Aberg.
8322 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
8323 (Output file names.): Add a test for the case when standard output
8326 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
8328 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
8329 to fix an oversight in the Bison 2.0 manual.
8331 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
8333 * NEWS: Version 2.0. Reformat the existing news items since
8334 1.875, so that related items are grouped together.
8335 * configure.ac (AC_INIT): Bump version to 2.0.
8336 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
8338 * tests/torture.at (Exploding the Stack Size with Alloca): Set
8339 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
8340 otherwise, we're not testing alloca. Unfortunately there's no
8341 simple way to consult HAVE_ALLOCA here.
8343 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
8346 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
8347 hand. This avoids a warning about comparing int to size_t when
8348 GCC warnings are enabled.
8350 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
8352 * NEWS: Bison-generated parsers no longer default to using the
8353 alloca function (when available) to extend the parser stack, due
8354 to widespread problems in unchecked stack-overflow detection.
8355 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
8356 responsibility to set it to a positive value. This lets the user
8357 specify a value that is not a preprocessor constant.
8358 * data/yacc.c (YYMAXDEPTH): Likewise.
8359 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
8360 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
8361 to be a compile-time constant. However, explain the constraints on it.
8362 Also, explain the constraints on YYINITDEPTH.
8363 (Table of Symbols): Explain that alloca is no longer the default.
8364 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
8367 * doc/bison.texinfo (Location Default Action): Mention that n must
8368 be zero when k is zero. Suggested by Frank Heckenbach.
8370 2004-12-22 Akim Demaille <akim@epita.fr>
8372 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
8373 (parser::state_type, parser::semantic_type, parser::location_type):
8374 Private, not public.
8375 (parser::parse): Return ints, not bool.
8376 Returning a bool introduces a problem: 0 corresponds to false, and
8377 it seems weird to return false on success. Returning true changes
8378 the conventions for yyparse.
8379 Alternatively we could return void and send an exception.
8380 There is no clear consensus (yet?).
8381 (state_stack, semantic_stack, location_stack): Rename as...
8382 (state_stack_type, semantic_stack_type, location_stack_type): these.
8383 Private, not public.
8384 * tests/c++.at: New.
8385 * tests/testsuite.at, tests/Makefile.am: Adjust.
8387 2004-12-21 Akim Demaille <akim@epita.fr>
8389 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
8391 2004-12-21 Akim Demaille <akim@epita.fr>
8393 Don't impose std::string for filenames.
8395 * data/lalr1.cc (b4_filename_type): New.
8396 (position::filename): Use it.
8397 (parser.hh): Move the inclusion of stack.hh and location.hh below
8398 the user code, so that needed headers for the filename type can be
8400 Forward declare them before the user code.
8401 * tests/Makefile.am (check-local, installcheck-local): Pass
8402 TESTSUITEFLAGS to the TESTSUITE.
8404 2004-12-20 Akim Demaille <akim@epita.fr>
8406 Use more STL like names: my_class instead of MyClass.
8408 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
8409 (SemanticStack, SemanticType, StateStack, StateType)
8410 (TokenNumberType, Stack, Slice, Traits, Parser::location)
8411 (Parser::value): Rename as...
8412 (location_stack, location_type, rhs_number_type, semantic_stack)
8413 (semantic_type, state_stack, state_type, token_number_type, stack)
8414 (slice, traits, parser::yylloc, parser::yylval): these.
8416 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
8418 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
8420 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
8421 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
8423 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
8425 Remove uses of 'short int' and 'unsigned short int'. This raises
8426 some arbitrary limits. It uses more memory but nowadays that's
8427 not much of an issue.
8429 This change does not affect the generated parsers; that's a different
8430 task, as some users will want to conserve memory there.
8432 Ideally we should use size_t to represent all object counts, and
8433 something like ptrdiff_t to represent signed differences of object
8434 counts; but that will require more code-cleanup than I have the
8435 time to do right now.
8437 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
8438 Use size_t, not int or short int, to count objects.
8439 * src/closure.c (nritemset, closure): Likewise.
8440 * src/closure.h (nritemset, closure): Likewise.
8441 * src/nullable.c (nullable_compute): Likewise.
8442 * src/print.c (print_core): Likewise.
8443 * src/print_graph.c (print_core): Likewise.

8445 * src/state.h (struct state): Likewise.
8446 * src/tables.c (default_goto, goto_actions): Likewise.
8448 * src/gram.h (rule_number, rule): Use int, not short int.
8449 * src/output.c (prepare_rules): Likewise.
8450 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
8451 errs, reductions): Likewise.
8452 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
8454 * src/tables.c (vector_number, tally, action_number,
8455 ACTION_NUMBER_MINIMUM): Likewise.
8456 * src/output.c (muscle_insert_short_int_table): Remove.
8458 2004-12-17 Akim Demaille <akim@epita.fr>
8460 * data/lalr1.cc: Extensive Doxygenation.
8461 (error_): Rename as...
8462 (error): this, since it is visible to the user.
8464 (Parser::message): Now an automatic variable from...
8465 (Parser::yyreport_syntax_error_): here.
8466 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
8468 * tests/input.at: Escape $.
8470 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
8472 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
8473 Parenthesize rhs to avoid obscure problems with mistakes like
8474 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
8475 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
8476 b4_rhs_location): Likewise.
8477 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
8478 b4_rhs_location): Likewise.
8480 2004-12-16 Akim Demaille <akim@epita.fr>
8482 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
8483 yacc.c: be sure to stay within yycheck_.
8484 * tests/actions.at: Re-enable C++ tests.
8486 2004-12-16 Akim Demaille <akim@epita.fr>
8488 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
8491 2004-12-16 Akim Demaille <akim@epita.fr>
8493 Use #define to handle the %name-prefix.
8495 * data/glr.c, data/yacc.c: Comment changes.
8496 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
8497 so that one can refer to yylex in the parser file, and have it
8498 renamed, as is the case with other skeletons.
8500 2004-12-16 Akim Demaille <akim@epita.fr>
8502 Move lalr1.cc internals into yy*.

8522 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
8524 Fix some problems reported by twlevo at xs4all.
8525 * src/symtab.c (symbol_new): Report an error if the input grammar
8526 contains too many symbols. This is better than calling abort() later.
8527 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
8528 (struct node, struct graph):
8529 Rename member expand to stretch. All uses changed.
8530 (struct graph): Remove member layoutalgorithm. All uses removed.
8531 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
8532 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
8534 (N_STRETCH): Rename from N_EXPAND. All uses changed.
8536 2004-12-15 Akim Demaille <akim@epita.fr>
8538 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
8539 Add more Doxygen comments.
8540 (symprint_, stack_print_, reduce_print_, destruct_, pop)
8541 (report_syntax_error_, translate_): Rename as...
8542 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
8543 (yypop_, yyreport_syntax_error_, yytranslate_): this.
8545 2004-12-15 Akim Demaille <akim@epita.fr>
8547 * data/lalr1.cc (lex_): Rename as...
8549 Move the trace here.
8550 Take the %name-prefix into account.
8551 Reported by Alexandre Duret-Lutz.
8553 2004-12-15 Akim Demaille <akim@epita.fr>
8555 Simplify the C++ parser constructor.
8557 * data/lalr1.cc (debug_): Rename as...
8558 (yydebug_): so that the parser's internals are always in the yy*
8561 (b4_parse_param_decl): Remove the leading comma as it is now only
8562 called as unique argument list.
8563 (Parser::Parser): Remove the constructor accepting a location and
8564 an initial debugging level.
8565 Remove from the other ctor the argument for the debugging level.
8566 (debug_level_type, debug_level, set_debug_level): New.
8568 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
8571 2004-12-15 Akim Demaille <akim@epita.fr>
8573 Remove b4_root related material: failure experiment
8574 (which goal was to allow to derive from a class).
8576 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
8577 definitions and uses.
8579 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
8581 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
8582 not 2, since it's not portable to subtract 1 from the start of an
8583 array. The new item 0 is never set or used. All uses changed.
8585 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
8586 the default definition of YYLLOC_DEFAULT. Problem reported
8587 by Frank Heckenbach.
8589 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
8591 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
8592 the normal case and one for the error case. Just use the
8593 first one uniformly. Problem reported by Frank Heckenbach.
8594 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
8595 use exactly the same macro in both places.
8596 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
8597 so that the normal-case YYRHSLOC works for the error case too.
8599 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
8600 (YYLLOC_DEFAULT): Use the same macro as glr.c.
8601 * doc/bison.texinfo (Location Default Action): Don't claim that
8602 we have an array of locations. Use the same macro for both glr
8603 and lalr parsers. Mention YYRHSLOC. Mention what happens when
8606 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
8608 * HACKING: Update email addresses to send announcements to.
8610 * configure.ac (AC_INIT): Bump version to 1.875f.
8612 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
8614 * NEWS: Version 1.875e.
8615 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
8617 * src/scan-skel.l: Include "complain.h", for "fatal".
8619 * src/relation.h (relation_print, relation_digraph):
8620 Relation sizes are of type relation_node, not size_t (this is
8621 merely a doc fix, since the two types are equivalent).
8622 (relation_transpose): Relation sizes are of type relation_node,
8624 * src/relation.c: Likewise.
8625 (top, infinity): Now of type relation_node, not int.
8626 (traverse, relation_transpose): Use relation_node, not int.
8628 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
8629 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
8630 (yyparse): Remove unused local introduced in 2004-10-25 patch.
8632 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
8633 specifying whether the test should be skipped. Use it tp
8634 specify that the [%defines %skeleton "lalr1.cc"] tests currently
8635 fail on some hosts, and should be skipped.
8637 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
8639 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
8640 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
8641 unless otherwise specified below.
8643 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
8644 to allocate kernel_base, kernel_items, kernel_size, since
8645 they needn't be initialized to 0.
8646 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
8647 * src/closure.c (new_closure): Likewise, for itemset.
8648 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

8660 (token_actions): Likewise for yydefact, actrow, conflrow,
8662 (save_column): Likewise for froms[symno], tos[symno].
8663 (goto_actions): Likewise for state_count.
8664 (pack_table): Likewise for base, pos, check.
8665 (tables_generate): Likewise for width.
8667 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
8668 for initial core. Just have a separate core, so we needn't worry
8669 about whether kernel_size and kernel_base are initialized.
8671 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
8672 kernel_size, kernel_items): Remove unnecessary initialization.
8673 * src/conflicts.c (conflicts): Likewise.

8677 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
8678 conflrow, conflict_table, conflict_list, table, check):
8681 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
8682 This is because all callers pass unsigned int.
8683 * src/closure.h (new_closure): Likewise.
8685 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
8686 (build_relations): Initialize includes[i] in all cases.
8687 * src/reader.c (packgram): Always initialize rules[ruleno].prec
8688 and rules[ruleno].precsym. Initialize members in order.
8689 * src/relation.c (relation_transpose): Always initialize new_R[i]
8691 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
8693 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
8694 conflict_list[0] was always 0, but now it isn't initialized.
8696 * src/table.c (table_grow): When conflict_table grew, the grown
8697 area wasn't cleared. Fix this.
8699 * lib/.cvsignore: Add strdup.c, strdup.h.
8700 * m4/.cvsignore: Add strdup.m4.
8702 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
8704 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
8705 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
8706 GOTO_NUMBER_MAXIMUM, since we occasionally compute
8707 ngotos + 1 without checking for overflow.
8708 (build_relations): Use END_NODE, not -1, to denote end of edges.
8709 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
8710 build_relations): Use goto_number, not int, for goto numbers.
8711 * src/tables.c (save_column, default_goto): Likewise.
8713 2004-11-23 Akim Demaille <akim@epita.fr>
8715 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
8716 of #defining from yystype.
8717 Don't typedef yystype, C++ does not need it.
8718 This lets it possible to forward declare it as union.
8720 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
8722 * bootstrap (gnulib_modules): Add extensions.
8723 Problem reported by Jim Meyering.
8725 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
8727 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
8728 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
8729 src/system.h, src/tables.c: XFREE -> free, to accommodate
8730 recent change to gnulib xalloc.h.
8731 Problem reported by Jim Meyering.
8733 2004-11-17 Akim Demaille <akim@epita.fr>
8735 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
8737 2004-11-17 Akim Demaille <akim@epita.fr>,
8738 Alexandre Duret-Lutz <adl@gnu.org>
8740 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
8743 Use it instead of cdebug_.
8744 (Parser::debug_stream, Parser::set_debug_stream): New.
8745 (Parser::symprint_): Define cdebug_ for temporary backward
8747 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
8750 2004-11-17 Akim Demaille <akim@epita.fr>
8752 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
8753 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
8754 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
8755 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
8757 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
8759 * data/glr.c (yyloc_default): Remove; not used.
8760 Problem reported by Frank Heckenbach.
8762 2004-10-25 Akim Demaille <akim@epita.fr>
8764 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
8765 Introduce another definition to address simple location arrays.
8766 (yyGLRStack): New member: yyerror_range.
8767 (yyrecoverSyntaxError, yyparse): Update it.
8768 (yyrecoverSyntaxError): Use it when shifting the error token to
8769 have an accurate range, equivalent to the one computed by both
8770 yacc.c and lalr1.cc.
8771 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
8772 that column numbers start at column 0, as per GNU Coding
8773 Standards, the others tests, and the doc.
8774 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
8775 Adjust to the above change (first column is 0).
8776 And adjust the location of the "<error>", now covering the whole
8779 2004-10-22 Akim Demaille <akim@epita.fr>
8780 and Paul Eggert <eggert@cs.ucla.edu>
8782 Remove some arbitrary limits on goto numbers and relations.
8783 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
8784 initial values, since they're never used.
8785 (set_goto_map): ngotos is now unsigned, so test for overflow
8786 by seeing whether it wraps around to zero.
8787 * src/lalr.h (goto_number): Now size_t, not short int.
8788 (GOTO_NUMBER_MAXIMUM): Remove.
8789 * src/relation.c (relation_print, traverse, relation_transpose):
8790 Check for END_NODE rather than looking at sign.
8791 * src/relation.h (END_NODE): New macro.
8792 (relation_node): Now size_t, not short int.
8794 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
8796 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
8797 keyword, not an identifier. Problem reported by Baron Schwartz in
8798 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
8800 2004-10-11 Akim Demaille <akim@epita.fr>
8802 * src/symtab.c (symbol_check_alias_consistency): Also check
8803 type names, destructors, and printers.
8804 Reported by Alexandre Duret-Lutz.
8805 Recode the handling of associativity and precedence in terms
8806 of symbol_precedence_set.
8807 Accept no redeclaration at all, not even equal to the previous
8809 (redeclaration): New.
8810 Use it to factor redeclaration complaints.
8811 (symbol_make_alias): Don't set the type of the alias, let
8812 symbol_check_alias_consistency do it as for other features.
8813 * src/symtab.h (symbol): Add new member prec_location, and
8815 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
8816 * tests/input.at (Incompatible Aliases): New.
8818 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
8820 .cvsignore fixes to accommodate gnulib changes,
8821 and the practice of naming build directories "_build".
8822 * .cvsignore: Add "_*". Sort.
8823 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
8824 * m4/.cvsignore: Add "*_gl.m4".
8826 2004-10-06 Akim Demaille <akim@epita.fr>
8828 * src/parse-gram.y (add_param): Fix the truncation of trailing
8831 2004-10-05 Akim Demaille <akim@epita.fr>
8833 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
8834 whether the reducion was empty or not. This leaves room to
8835 improve the use of YYLLOC_DEFAULT in such a case.
8836 lalr1.cc is still experimental, so changing this is acceptable.
8837 And finally, there are probably not many users who changed the
8838 handling of locations in GLR, so changing is admissible too.
8840 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
8841 empty reduction, set @$ to an empty location ending the previously
8843 Adjust uses to make sure the code is triggered on empty
8845 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
8846 expected output: empty reductions have empty locations.
8848 2004-09-29 Akim Demaille <akim@epita.fr>
8850 * data/lalr1.cc: Move towards a more standard C++ coding style
8851 for templates: Class < T > -> Class<T>.
8853 2004-09-29 Akim Demaille <akim@epita.fr>
8855 * data/lalr1.cc: Reinstall the former ctor, for sake of
8856 compatibility, but warn it will be removed.
8857 Move towards a more standard C++ coding style (i.e., type *var ->
8860 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
8862 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
8863 since it's less likely to work if NULs are involved in the future.
8865 2004-09-27 Akim Demaille <akim@epita.fr>
8867 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
8869 2004-09-27 Akim Demaille <akim@epita.fr>
8871 * data/lalr1.cc (b4_parse_param_decl_1): New.
8872 (b4_parse_param_decl): Use it to have different names between attribute
8874 (b4_cc_constructor_call): Likewise.
8876 2004-09-24 Akim Demaille <akim@epita.fr>
8878 * src/parse-gram.y (add_param): Strip the leading and trailing
8879 blanks from a formal argument declaration.
8880 (YY_LOCATION_PRINT): New.
8882 2004-09-24 Akim Demaille <akim@epita.fr>
8884 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
8887 2004-09-24 Akim Demaille <akim@epita.fr>
8889 * doc/bison.texinfo (Table of Symbols): Sort.
8891 2004-09-21 Akim Demaille <akim@epita.fr>
8893 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
8894 the useless parentheses.
8895 Suggested by Paul Eggert.
8897 2004-09-20 Akim Demaille <akim@epita.fr>
8899 Let the initial-action act on the look-ahead, and use it for the
8900 "initial push" (corresponding to an hypothetical beginning-of-file).
8901 And let lalr1.cc honor %initial-action.
8903 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
8905 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
8906 (Parser::Parser): Remove the ctor that used to initialize it.
8907 (Parser::parse): Like in the other skeletons, issue the "starting
8908 parse" message before any action.
8909 Honor %initial-action.
8910 Initialize the stacks with the lookahead.
8911 * data/yacc.c: Let $$ and @$ in %initial-action designate the
8913 Push them in the stacks.
8914 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
8916 2004-09-20 Akim Demaille <akim@epita.fr>
8918 * doc/bison.texinfo (Initial Action Decl): New.
8920 2004-09-20 Akim Demaille <akim@epita.fr>
8922 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
8923 clearer criterion to define it.
8924 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
8925 When reducing on an empty RHS, use the latest stacked location as
8927 yylloc is not always available.
8928 * data/glr.c: Likewise.
8929 Also, honor initial-actions.
8931 2004-09-20 Akim Demaille <akim@epita.fr>
8933 * data/yacc.c (YY_LOCATION_PRINT): New.
8934 Define when we know YYLTYPE's structure, i.e., when the default
8935 YYLLOC_DEFAULT is used.
8936 * data/c.m4 (b4_yysymprint_generate): Use it.
8937 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
8938 value of the result.
8939 (error_start_): Replace with...
8940 (error_range_): this location array.
8941 This allows to replace code relying on the implementation of
8942 locations by portable code.
8943 * data/yacc.c (yylerrsp): Replace with...
8944 (yyerror_range): this.
8945 Every time a token is popped, update yyerror_range[0], to have an
8946 accurate location for the error token.
8947 * data/glr.c (YY_LOCATION_PRINT): New.
8948 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
8949 deference a pointer.
8950 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
8951 report the location in %printers.
8953 * src/scan-skel.l: Instead of abort, report error messages to ease
8954 understanding skeleton scanning failures.
8956 2004-09-16 Akim Demaille <akim@epita.fr>
8958 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
8959 (iterator, const_iterator): these, to be more in the C++ spirit.
8960 Also, return reverse iterators so that when displaying the stack
8961 we display its bottom first.
8962 (Parser::stack_print_, Parser::reduce_print_): Match the messages
8964 We should probably use vector here though.
8966 2004-09-16 Akim Demaille <akim@epita.fr>
8968 Have more complete shift traces.
8970 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
8971 to report Shifts instead of ad hoc YYDPRINTF invocations,
8972 including for the error token.
8973 * data/lalr1.cc (symprint_): Output the location.
8974 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
8975 output the location within the %printer.
8976 Activate GLR tests, at least to make sure they compile properly.
8977 They still don't pass though.
8978 * tests/calc.at: Adjust expect verbose output, since now "Entering
8979 state..." is on a different line than the "Shifting" message.
8981 2004-09-08 Akim Demaille <akim@epita.fr>
8983 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
8984 Bison directive from the Bison file to the invocation of this
8985 macro, so that these directives are passed to
8986 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
8987 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
8988 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
8989 the extra Bison directives instead of the whole series.
8990 Change the grammar so that there are recoverable errors, and
8991 unrecoverable errors. Now we can have the parser give up before
8992 consuming the whole input. As a result we now can observe that
8993 the lookahead is freed when needed.
8994 Change the parser source to parse argv[1] instead of a hard coded
8996 Simplify yylex, and give a value and location to EOF.
8997 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
8998 passed directives already coded in the file.
8999 Add some tests to check the location of "error".
9000 For some tests, the C++ parser is correct, and not yacc.c.
9001 For other tests, they provide different, but unsatisfying, values,
9002 so keep the C++ value so that at least one parser is "correct"
9003 according to the test suite.
9004 (Actions after errors): Remove, this is subsumed by the
9005 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
9007 2004-09-06 Akim Demaille <akim@epita.fr>
9009 * data/lalr1.cc: Adjust the indentation of the labels.
9013 2004-09-06 Akim Demaille <akim@epita.fr>
9015 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
9016 argument, an informative message.
9017 Call YY_SYMBOL_PRINT.
9018 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
9019 * data/lalr1.cc (destruct_): Likewise.
9020 In addition, no longer depend on b4_yysymprint_generate and
9021 b4_yydestruct_generate to generate these functions, do it "by
9024 2004-09-03 Akim Demaille <akim@epita.fr>
9026 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
9027 invoked, yydestruct the lookahead.
9028 * tests/calc.at (Calculator $1): Update the expected lengths of
9029 traces: there is an added line for the discarded lookahead.
9030 * doc/bison.texinfo (Destructor Decl): Some rewording.
9031 Define "discarded" symbols.
9033 2004-09-02 Akim Demaille <akim@epita.fr>
9035 * data/lalr1.cc (translate_, destruct_): No reason to be static.
9037 2004-09-02 Akim Demaille <akim@epita.fr>
9039 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
9040 (YYDSYMPRINTF): Rename as...
9041 (YY_SYMBOL_PRINT): this.
9042 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
9044 Use it instead of direct symprint_ calls.
9045 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
9048 2004-09-02 Akim Demaille <akim@epita.fr>
9050 * data/lalr1.cc (b4_yysymprint_generate): New.
9051 (symprint_): New member function, defined when YYDEBUG.
9052 Use it consistently instead of token/nterm debugging output by
9054 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
9055 %printer calls to use cdebug_ when using lalr1.cc.
9057 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
9059 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
9060 with #ifdef YYDEBUG.
9062 2004-08-26 Akim Demaille <akim@epita.fr>
9064 * doc/bison.texinfo (Implementing Loops): Rename as...
9065 (Implementing Gotos/Loops): this.
9067 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
9069 Adjust to latest gnulib.
9070 * bootstrap (gnulib_modules): Add xalloc-die.
9071 Set LC_ALL=C so that file names sort consistently.
9072 Prefer the gnulib copies of gettext.m4, glibc21.m4,
9073 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
9074 uintmax_t.m4, ulonglong.m4.
9075 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
9076 po.m4 since we are now using _gl.m4 instead.
9078 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
9080 * src/scan-action.l: Remove. Scanning of semantic actions is
9081 handled in scan-gram.l.
9083 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
9085 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
9087 * src/location.h (struct): The file member is a uniqstr.
9088 (equal_boundaries): Use UNIQSTR_EQ for comparison.
9090 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
9092 Fix bug with non-%union parsers that have printers or destructors,
9093 which led to a Bison core dump. Reported by Peter Fales in
9094 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
9096 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
9097 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
9098 not to our own type.
9099 * src/output.c (symbol_destructors_output, symbol_printers_output):
9100 Don't assume %union.
9101 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
9102 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
9103 UNION-FLAG. All callers changed.
9104 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
9105 Use type char, not unsigned int, when declaring an array of char;
9106 this lets us remove a cast.
9107 (Printers and Destructors): Add non-%union test cases.
9109 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9111 * doc/bison.texinfo: Minor editorial changes, mostly to the new
9112 GLR writeups. E.g., avoid frenchspacing and the future tense,
9113 change "lookahead" to "look-ahead", and change "wrt" to "with
9116 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9118 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
9119 New sections, split off from the GLR Parsers section. Put the new
9120 Simple GLR Parser near the start of the GLR section, for clarity.
9121 Rewrite connective text.
9123 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
9125 * doc/bison.texinfo (Simple GLR Parsers): New section.
9127 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9129 * NEWS, TODO, doc/bison.texinfo:
9130 Use "look-ahead" instead of "lookahead", to be consistent.
9131 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
9132 while we're fixing "look-ahead".
9133 * src/conflicts.c (shift_set): Renamed from shiftset.
9134 (look_ahead_set): Renamed from lookaheadset.
9135 * src/print.c: Likewise.

9154 * README: Update location of patched M4 distribution.
9156 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
9158 Don't assume the C++ compiler takes the same arguments as the C compiler
9160 * configure.ac (O0CXXFLAGS): New var.
9161 * tests/atlocal.in (CXXFLAGS): Use it.
9163 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
9165 Fix some "make check" problems with C++ reported by
9166 Albert Chin-A-Young for Tru64 C++ in this thread:
9167 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
9169 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
9170 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9171 Output to a .cc file for C++, not to a .c file.
9172 * tests/calc.at (AT_CHECK_CALC): Likewise.
9173 * tests/regression.at (AT_CHECK_DANCER): Likewise.
9174 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.

9179 C++ compiler. (trivial change)
9181 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
9183 Spent a few hours checking out which prerequisite versions the
9184 current sources actually require. I went all the way back to
9185 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
9186 a seemingly endless set of combinations of versions more recent
9187 than that. The bottom line is that the current sources require
9188 fairly recent versions of the build tools, and it'll be some work
9190 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
9191 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
9192 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
9193 Add comments explaining why those particular versions are
9196 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
9197 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
9198 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
9200 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
9201 (it fails with a Autoconf-without-aclocal-m4 diagnostic).

9215 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
9216 * README-alpha: Don't tell people not to package this.
9218 * bootstrap: Don't assume $(...) works; use `...` instead.
9219 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
9222 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
9223 put into the -d output file, and mention what to do if YYSTYPE is
9226 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9228 Undo change made earlier today: it caused autopoint to not bring
9229 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
9232 * bootstrap: Check that gettext version matches what's in
9233 configure.ac. Warn users to ignore robots.txt ERROR 404.
9234 * bootstrap: Undo today's earlier change (logged below).
9235 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
9237 The gettext version checking is causing more trouble than it's
9238 curing; remove it. Problem reported by Paul Hilfinger.
9240 * bootstrap: Issue a warning that one can expect a message
9241 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
9242 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
9244 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
9246 Ensure that the C++ compiler used for testing actually works on a
9247 simple test program; if not, skip the C++-related tests. Problem
9248 reported by Vin Shelton in:
9249 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html

9259 being generated, as the GLR parser needs it even in that case.
9260 Problem reported by Troy A. Johnson

9272 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
9273 lalr1.cc runs afoul of the first, and the last two are no longer
9274 supported by GCC 3.4.0.
9275 * README: Mention GNU m4 1.4 or later; mention m4 patches.
9276 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
9278 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>

9313 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
9314 * src/.cvsignore: Add *.output.
9316 * src/parse-gram.y: Put copyright notice inside %{ %} so it
9317 gets copied to the output file.
9319 2004-04-28 Paul Eggert <eggert@twinsun.com>
9321 Get files from the gnulib and po repositories, instead of relying
9322 on them being in our CVS. Upgrade to latest versions of gnulib
9325 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
9326 * bootstrap: Bootstrap from gnulib and po repositories.
9327 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
9328 * README-cvs: Document these changes. Remove version numbers from

9334 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
9336 (AC_ISC_POSIX): Remove; we no longer support this
9337 ancient OS, as it gets in the way of latest Autoconf & gnulib.
9338 (AC_HEADER_STDC): Remove: we now assume C89 or better.
9339 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
9340 Do not check for C89 headers, except for locale.h which is used
9341 by the Yacc library and must port to K&R hosts.

9343 Do not check for C89 functions, except for setlocale which is
9344 used by the Yacc library.

9355 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
9356 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):

9392 Remove, as these files are now generated automatically
9393 by bootstrap or automake.

9423 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
9424 case, as stos_ is now used by destructors due to the 2004-02-09
9427 Remove more K&R C support.

9446 with latest obstack.h.
9447 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
9448 to procedure types, as obstack.h now does that for us.
9449 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
9451 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
9452 so that this include file can stand alone.
9453 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
9454 does this now. Include subpipe.h first after config.h, to
9455 test whether it can stand alone.
9457 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
9458 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the

9462 the union, because empty unions aren't allowed in C. Caught
9465 2004-04-13 Jim Meyering <jim@meyering.net>
9467 * src/conflicts.c (conflicts_print): Correct format string typo:

9533 2004-03-08 Paul Eggert <eggert@gnu.org>
9535 Add support for hex token numbers. Suggested by Odd Arild Olsen in
9536 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
9538 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor

9541 * src/scan-gram.l (scan_integer): New function.
9543 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
9544 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
9545 handle_action_dollar, handle_action_at, convert_ucn_to_byte):

9565 token which are discarded.
9566 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
9567 error_start_ when erroneous token are discarded.
9568 (Parser::parse) <yyerrlab1>: Compute the location of the error
9569 token so that it covers all the discarded tokens.
9570 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
9571 it can be called with `%skeleton "lalr1.cc"', and do that.
9573 2004-02-02 Paul Eggert <eggert@twinsun.com>
9575 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
9576 $(top_srcdir)/lib and ../lib. This fixes a bug reported
9577 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
9578 There's no need to mention top_builddir since Automake does that
9580 (INCLUDES): Remove, as Automake says it's obsolescent.
9581 Contents migrated into AM_CPPFLAGS as described above.

9593 resulting parsers are compilable with C++.
9595 2003-12-23 Paul Eggert <eggert@twinsun.com>
9597 * config/depcomp, config/install-sh: Sync with Automake 1.8.
9598 * src/output.c (output_skeleton): Rename local var.
9599 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
9600 Bison tokens, as this runs afoul of the 2003-10-07 change that
9601 disallowed NUL bytes in character constants or string literals.
9603 * tests/local.at: Require Autoconf 2.59's Autotest.
9604 * tests/testsuite.at: Don't include local.at, since we now assume
9605 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
9607 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
9608 multiple inclusion warnings.
9610 2003-12-02 Akim Demaille <akim@epita.fr>

9705 When reducing initial empty rules, Bison parser read an initial
9706 location that is not defined. This results in garbage, and that
9707 affects Bison's own parser. Therefore we need (i) to extend Bison
9708 to support a means to initialize this location, and (ii) to use
9709 this CVS Bison to fix CVS Bison's parser.

9750 Also, augment the similarity between lalr1.cc and yacc.c.
9751 Note: the locations of error recovery rules are not correct yet.

9754 lalr1.cc and yacc.c.
9755 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
9756 (yyerrlab1): Remove, but where it used to be (now the bottom part of
9757 yyerrlab), when hitting EOF, pop the whole stack here instead of
9758 merely falling thru the default error handling mechanism.
9759 (yyerrorlab): New label, with the old contents of YYERROR,
9760 plus the following change: pop the stack of rhs corresponding
9761 to the production that invoked YYERROR. That is how Yacc
9762 behaves (required by POSIX).
9763 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to

9768 Tune local.at so that people can "autom4te -l autotest calc.at -o

9788 * data/glr.c (YYASSERT): New macro.
9789 (yyfillin, yydoAction, yyglrReduce, yysplitStack,

9798 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>

9891 `How Can I Reset @code{yyparse}', since texinfo does not allow
9892 arbitrary @ in node names.
9894 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
9895 shouldn't be needed according to the gettext 0.12.1 documentation
9896 but which seem to be needed anyway: codeset.m4 glibc21.m4

9919 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
9920 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
9921 the tests right now.
9922 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
9923 yyerror are declared before use; C99 requires this.
9925 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
9927 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
9929 (yyrecoverSyntaxError): Correct the logic for setting and testing
9931 Correct comment on handling EOF.
9932 Allow states with only a default reduction, rather than failing
9933 (I can't quite reconstruct why these were not allowed before).
9935 Fixes to avoid problem that $-N rules in GLR parsers can cause
9936 buffer overruns, corrupting state.
9938 * src/output.c (prepare_rules): Output max_left_semantic_context
9940 * src/reader.h (max_left_semantic_context): New variable declaration.

9958 to differentiate output with and without locations.
9959 Remove forward declarations of yylex and yyerror---caused errors
9960 because default YYLTYPE not yet defined.
9961 Change semantic actions to compute strings, rather than printing
9962 them directly (to test proper passing of semantics values). Change
9963 output to prefix notation and update test data and expected results.
9964 (yylex): Track locations.
9965 (stmtMerge): Return value rather than printing, and include arguments

9978 Rename local vars to avoid warnings.
9979 * tests/glr-regression.at (Improper handling of embedded actions
9980 and $-N in GLR parsers): Remove unused local variable from yylex.
9981 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
9982 (void) as arg when not pure, since we now assume C89 when building
9983 Bison. Pacify GCC by using parameter.

9987 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
9988 yy::Location::lines, yy::Location::columns): Rename arguments
9989 to avoid shadowing; this removes a warning generated by GCC 3.3.

9993 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
9994 to g++, as GCC 3.3 complains if you do it.

9996 everything that WARNING_CFLAGS has, except omit warnings
9997 not suitable for C++.

9999 * tests/atlocal.in (CXXFLAGS): New var.
10000 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
10002 Fix a GLR parser bug I reported in February; see
10003 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
10004 The problem was that GLR parsers did not conform to the C standard,
10005 because actions like { $1 = $2 + $3; } expanded to expressions
10006 that invoked YYFILL in separate subexpressions, and YYFILL assigned
10007 to a local variable. The C standard says that expressions
10008 like (var = f ()) + (var = f ()) have undefined behavior.
10009 Another problem was that GCC sometimes issues warnings that
10010 yyfill and its parameters are unused.
10012 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
10013 as possibly unused.
10014 (yyfill): New function.
10016 (yyuserAction): Change type of yynormal to bool, so that it matches
10017 the new yyfill signature. Mark it as possibly unused.
10020 Follow up on a bug I reported in February, where a Bison-generated
10021 parser can loop. Provide a test case and a fix for yacc.c. I
10022 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10023 The original bug report is in:
10024 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
10026 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10027 macro's size was becoming unwieldy.
10028 (yyerrlab): Do not discard an empty lookahead symbol, as this
10029 might destroy garbage.
10030 (yyerrorlab): New label, with the old contents of YYERROR,
10031 plus the following change: pop the stack of rhs corresponding
10032 to the production that invoked YYERROR. That is how Yacc
10033 behaves, and POSIX requires this behavior.
10034 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10035 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10036 Define 'alarm' to do nothing if unistd.h is not available.
10037 Add a new rule "exp: '-' error;" to test the above change to
10038 data/yacc.c. Use 'alarm' to abort any test taking longer than
10039 10 seconds, as it's probably looping.
10040 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10041 Also, the new yacc.c generates two fewer diagnostics for an
10044 2003-05-24 Paul Eggert <eggert@twinsun.com>
10046 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
10047 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
10048 This fixes a problem reported by John Bowman when the Compaq/HP
10049 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
10050 -ansi -Wall -gall).
10051 * data/yacc.c (union yyalloc): Likewise.
10052 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
10054 Switch from 'int' to 'bool' where that makes sense.
10056 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
10057 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
10058 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
10059 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
10060 Return or accept bool, not int. All callers changed.
10061 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
10062 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.
10063 * lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_,
10064 bitset_copy_, bitset_op4_cmp, bitset_and_or_cmp_, bitset_andn_or_cmp_,
10065 bitset_or_and_cmp_): Likewise.
10066 * lib/bitset.h (bitset_test, bitset_only_set_p): Likewise.
10067 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,

10079 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
10080 lbitset_xor_cmp): Likewise.
10081 * lib/bbitset.h: Include <stdbool.h>.
10082 (struct bitset_vtable): The following members now return bool, not
10083 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
10084 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
10086 * src/conflicts.c (count_rr_conflicts): Likewise.
10087 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
10089 * lib/ebitset.c (ebitset_obstack_init): Likewise.
10090 * lib/lbitset.c (lbitset_obstack_init): Likewise.
10091 * src/getargs.c (debug_flag, defines_flag, locations_flag,
10092 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
10093 graph_flag): Likewise.
10094 * src/getargs.h (debug_flag, defines_flag, locations_flag,

10097 * src/output.c (error_verbose): Likewise.
10098 * src/output.h (error_verbose): Likewise.
10099 * src/reader.c (start_flag, typed): Likewise.

10102 (long_options, getargs): Use it.
10103 * src/lalr.c (build_relations): Use bool, not int.
10104 * src/nullable.c (nullable_compute): Likewise.

10108 * src/output.c (prepare): Use it.
10109 * src/output.c (token_definitions_output,
10110 symbol_destructors_output, symbol_destructors_output): Use string,
10111 not boolean integer, to keep track of whether to output separator.
10112 * src/print_graph.c (print_core): Likewise.
10113 * src/state.c (state_rule_lookaheads_print): Likewise.
10115 * config/install-sh: Sync from automake 1.7.5.
10117 2003-05-14 Paul Eggert <eggert@twinsun.com>
10119 * src/parse-gram.y (rules_or_grammar_declaration): Require a
10120 semicolon after a grammar declaration, in the interest of possible
10121 future changes to the Bison input language.
10122 Do not allow a stray semicolon at the start of the grammar.
10123 (rhses.1): Allow one or more semicolons after any rule, including
10124 just before "|" as required by POSIX.
10125 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
10128 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
10130 %parse-param support for lalr1.cc.
10132 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
10133 b4_cc_constructor_calls, b4_cc_constructor_call,
10134 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
10136 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
10137 parse-param arguments.
10138 (yy::b4_parser_class_name): Declare instance variables to
10139 hold parse-param arguments.
10140 * tests/calc.at: s/value/semantic_value/ because value clashes
10141 with a member of yy::b4_parser_class_name. Adjust C++ code
10142 to handle %parse-param. Enable %parse-param test in C++.
10144 2003-05-12 Paul Eggert <eggert@twinsun.com>
10146 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
10147 English a bit. Fix fclose typo. Change "const char" to "char
10148 const", and use ANSI C rather than K&R for "main". Suggest
10149 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
10150 and suggest yy_switch_to_buffer.
10152 2003-05-05 Paul Eggert <eggert@twinsun.com>
10154 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
10155 C89. This avoids a diagnostic on compilers that define __STDC__
10156 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
10157 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10159 2003-05-03 Paul Eggert <eggert@twinsun.com>
10161 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
10162 Do not overrun array bounds.
10163 This should fix a bug reported today by Olatunji Oluwabukunmi in
10164 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
10166 2003-04-29 Akim Demaille <akim@epita.fr>
10168 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
10169 * src/getargs.c, src/getargs.h: here, as bool, not int.
10170 (nondeterministic_parser): New.
10171 * src/parse-gram.y, src/scan-gram.l: Support
10172 %nondeterministic-parser.
10173 * src/output.c (prepare): Use nondeterministic_parser instead
10174 of glr_parser where appropriate.
10175 * src/tables.c (conflict_row, action_row, save_row)
10176 (token_actions, token_actions, pack_vector): Ditto.
10178 2003-04-29 Akim Demaille <akim@epita.fr>
10180 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
10182 2003-04-29 Akim Demaille <akim@epita.fr>
10184 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
10185 with %pure-parser and %locations to exercise the patch from Yakov
10188 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
10190 * data/yacc.c: (b4_lex_param): Corrected for the case where
10191 %lex-param is provided and %pure-parser isn't.
10193 2003-04-27 Paul Eggert <eggert@twinsun.com>
10195 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
10196 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
10197 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
10198 if it is not defined.
10199 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
10201 2003-04-26 Paul Eggert <eggert@twinsun.com>
10203 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
10204 Declare to be of type suitable for the ninf value itself, not of
10205 type suitable for the corresponding table, since the latter might
10206 be unsigned but the ninf value might be negative. This fixes a
10207 bug reported by Alexandre Duret-Lutz in
10208 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
10210 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
10211 invokes it. We shouldn't invoke it twice because it will attempt
10212 to put error.o in the archive twice. This fixes a glitch reported
10213 by Martin Mokrejs in
10214 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10216 2003-04-21 Paul Eggert <eggert@twinsun.com>
10218 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
10221 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
10223 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
10224 Fix obvious typo that results in uncompilable GLR parsers
10225 when both %pure-parser and %locations are used. (trivial change)
10227 2003-04-17 Paul Eggert <eggert@twinsun.com>
10229 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
10230 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
10231 Do not insert the expected token via unput, as this runs afoul
10232 of a POSIX-compatibility bug in flex 2.5.31.
10233 All uses changed to BEGIN the parent state,
10234 since we no longer insert the expected token via unput.
10235 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
10236 that is no longer emitted after the above change.
10238 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
10239 the first one. This change is from Paul Hilfinger, and it fixes
10240 regression reported by Werner Lemberg in
10241 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
10243 (resolve_sr_conflict): Don't invoke state_errs_set
10244 unless one or more tokens have been explicitly made errors.
10245 Otherwise, the above change causes Bison to abort.
10247 * tests/existing.at (GNU pic Grammar): New test case, taken from
10250 2003-03-31 Akim Demaille <akim@epita.fr>
10252 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
10254 2003-03-31 Akim Demaille <akim@epita.fr>
10256 * src/output.c (prepare_symbols): Avoid trailing spaces in the
10259 2003-03-31 Akim Demaille <akim@epita.fr>
10261 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
10262 From Paul Hilfinger.
10264 2003-03-29 Akim Demaille <akim@epita.fr>
10266 * m4/error.m4: Do not put under dynamic conditions some code which
10267 expansion is under static control.
10269 2003-03-29 Akim Demaille <akim@epita.fr>
10271 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
10273 2003-03-29 Akim Demaille <akim@epita.fr>
10275 * doc/bison.texinfo (Strings are Destroyed): New.
10277 2003-03-13 Paul Eggert <eggert@twinsun.com>
10279 * .cvsignore: Add configure.lineno.
10280 * src/.cvsignore: Add yacc.
10281 * tests/.cvsignore: Add testsuite.log.
10282 * doc/fdl.texi: Sync with latest FSF version.
10284 2003-03-12 Paul Eggert <eggert@twinsun.com>
10286 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
10287 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
10288 cursor, instead of leaving it undefined. This fixes a bug
10289 reported by Tim Van Holder in
10290 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
10291 * tests/input.at (Torturing the Scanner): Test the scanner on
10292 an empty input file, which was Tim Van Holder's test case.
10294 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
10295 <sys/resource.h> can be included, include sys/time.h and
10296 sys/times.h first, if available. This works around the SunOS
10297 4.1.4 porting bug reported by Bruce Becker in
10298 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
10300 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
10301 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
10302 AC_HEADER_SYS_WAIT.
10304 Merge changes from gnulib. This was prompted because the CVS
10305 snapshot didn't build on Solaris 7 due to strnlen problems.
10307 These changes need to be merged back into gnulib:
10308 * lib/hash.c: Include <stdbool.h> unconditionally.
10309 * m4/onceonly.m4 (m4_quote): New macro.
10310 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
10311 Quote AC_FOREACH variable-expansions properly.
10312 The 2003-01-03 obstack.h change also needs merging.
10313 {end of changes requiring merging}
10315 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
10316 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
10317 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
10318 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
10319 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
10320 New files, imported from gnulib.
10321 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
10324 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
10325 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
10328 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
10330 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
10331 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
10332 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
10333 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
10334 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
10335 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
10336 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
10337 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
10338 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
10339 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
10340 (jm_PREREQ_ARGMATCH): Remove.
10341 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
10342 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
10344 * src/system.h: Include <stdbool.h> unconditionally.
10346 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
10347 assuming at least C89 in the bitset code for some time now.
10349 2003-03-03 Akim Demaille <akim@epita.fr>
10353 2003-03-02 Akim Demaille <akim@epita.fr>
10355 * doc/bison.texinfo (Table of Symbols): Reactivate the
10356 documentation for %lex-param, and %parse-param.
10358 2003-03-02 Akim Demaille <akim@epita.fr>
10360 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
10361 generate verbose error messages.
10362 Use the number of tokens as an upper bound in yytname, as it
10363 cannot be a non terminal.
10365 2003-03-02 Akim Demaille <akim@epita.fr>
10367 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
10370 2003-03-02 Akim Demaille <akim@epita.fr>
10372 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
10373 Use them to exercise yycheck overrun.
10374 Based on Andrew Suffield's grammar.
10376 2003-03-02 Akim Demaille <akim@epita.fr>
10378 Create tests/local.at for Bison generic testing macros.
10380 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
10381 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
10383 * tests/calc.at (AT_CHECK_CALC): Adjust.
10384 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
10385 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
10386 * tests/local.at: here.
10387 (AT_COMPILE_CXX): Tags the tests using it as c++.
10388 Ignore the test if CXX is not functional.
10390 2003-03-01 Paul Eggert <eggert@twinsun.com>
10392 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
10393 not loc->end, since loc->end might contain garbage and this leads
10394 to undefined behavior on some platforms.
10395 (id_loc, token_start): Use (IF_LINTed) initial values that do not
10396 depend on *loc, so that the reader doesn't give the the false
10397 impression that *loc is initialized.
10398 (<INITIAL>"%%"): Do not bother setting code_start, since its value
10399 does not survive the return.
10401 2003-03-01 Akim Demaille <akim@epita.fr>
10403 * src/scan-gram.l (code_start): Always initialize it when entering
10404 into yylex, as SC_EPILOGUE is activated *before* the corresponding
10405 yylex invocation. An alternative would be making it static, but
10406 then it starts with the second %%'s beginning, instead of its end.
10408 2003-02-28 Paul Eggert <eggert@twinsun.com>
10410 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
10411 around a UnixWare 7.1.1 porting bug reported by John Hughes in
10412 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
10414 2003-02-26 Paul Eggert <eggert@twinsun.com>
10416 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
10417 Remove Sequent/Pyramid discussion (nobody uses them any more).
10418 Merge VMS and MS-DOS discussion; these ports may well be dead
10419 but let's keep mentioning them for now. Put <> around email
10420 addresses. Add copyright notice.
10422 2003-02-24 Paul Eggert <eggert@twinsun.com>
10424 * data/glr.c (yy_reduce_print): yylineno -> yylno,
10425 to avoid collision with flex use of yylineno.
10426 Problem reported by Bruce Lilly in
10427 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
10428 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
10429 * data/yacc.c (yy_reduce_print): Likewise.
10431 * config/depcomp: Sync with Automake 1.7.3.
10433 2003-02-21 Akim Demaille <akim@epita.fr>
10435 * data/lalr1.cc: Use temporary variables instead of casts to
10436 change integer types.
10437 Suggested by Paul Eggert.
10439 2003-02-21 Akim Demaille <akim@epita.fr>
10441 * doc/bison.texinfo: Use "location" consistently to refer to @n,
10442 to avoid confusions with lalr1.cc's notion of Position.
10443 Suggested by Paul Eggert.
10445 2003-02-20 Akim Demaille <akim@epita.fr>
10447 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
10448 before initial_columns.
10449 (location.hh): Use consistent variable names when defining the
10451 Use "last" so that we subtract from Positions, not from unsigned.
10453 2003-02-20 Akim Demaille <akim@epita.fr>
10455 * data/lalr1.cc (position.hh): New subfile, including the extended
10456 and Doxygen'ed documentation of class Position.
10457 (location.hh): Use it.
10458 Document a` la Doxygen.
10459 With the help of Benoit Perrot.
10461 2003-02-20 Akim Demaille <akim@epita.fr>
10463 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
10465 Redefine AT_YYERROR_SEES_LOC_IF using it.
10466 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
10468 Don't use the location in yy::Parser::error_ and
10469 yy::Parser::print_ when not %locations.
10470 Activate more lalr1.cc tests.
10472 2003-02-19 Akim Demaille <akim@epita.fr>
10474 * data/lalr1.cc: When displaying a line number, be sure to make it
10477 2003-02-19 Akim Demaille <akim@epita.fr>
10479 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
10481 (YYABORT, YYACCEPT, YYERROR): New.
10482 * tests/calc.at: Renable the lalr1.cc test.
10484 2003-02-19 Akim Demaille <akim@epita.fr>
10486 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
10487 error recovery, mixing with/without pops and discarding of the
10490 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
10492 2003-02-17 Paul Eggert <eggert@twinsun.com>
10494 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
10495 * tests/testsuite.at (AT_COMPILE): Use them.
10496 This fixes the testsuite problem reported by Robert Lentz in
10497 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
10499 2003-02-12 Paul Eggert <eggert@twinsun.com>
10501 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
10502 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
10503 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
10504 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
10505 Check for malloc failure, for consistency with yacc.c.
10506 (yytname_size): Remove, for consistency with yacc.c.
10508 The bug still remains in data/lalr1.cc, as I didn't have time
10511 2003-02-06 Akim Demaille <akim@epita.fr>
10513 * configure.ac (GXX): Rename as...
10514 (CXX): this, to keep the original Autoconf semantics.
10516 * data/lalr1.cc: Fix b4_copyright invocations.
10517 If YYDEBUG is not defined, don't depend upon name_ being defined.
10518 (location.hh): Include string and iostream.
10519 (Position::filename): New member.
10520 (Position::Position ()): New.
10521 (operator<< (Position)): New.
10522 (operator- (Position, int)): New.
10523 (Location::first, Location::last): Rename as...
10524 (Location::begin, Location::end): these, to mock the conventional
10526 (operator<< (Location)): New.
10527 * tests/atlocal.in (CXX): New.
10528 * tests/testsuite.at (AT_COMPILE_CXX): New.
10529 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
10530 locations in a more synthetic way.
10531 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
10533 Adjust the C locations to match those from Emacs: first column is
10535 Change all the expected results.
10536 Conform to the GCS: simplify the locations when applicable.
10537 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
10538 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
10539 these CPP macros with the m4 macros new defined by...
10540 (AT_CHECK_PUSHDEFS): this, i.e.:
10541 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
10542 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
10544 (AT_CHECK_POPDEFS): Undefine them.
10545 (AT_CHECK_CALC_LALR1_CC): New.
10546 Use it for the first lalr1.cc test.
10548 2003-02-04 Akim Demaille <akim@epita.fr>
10550 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
10551 Location as is defined.
10553 2003-02-04 Akim Demaille <akim@epita.fr>
10555 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
10556 name_ being defined.
10558 2003-02-03 Paul Eggert <eggert@twinsun.com>
10560 * src/gram.h (start_symbol): Remove unused decl.
10562 Use more-consistent naming conventions for local vars.
10564 * src/derives.c (derives_compute): Change type of local var from
10565 int to rule_number.
10566 * src/gram.c (grammar_rules_partial_print): Likewise.
10567 * src/print.c (print_core): Likewise.
10568 * src/reduce.c (reduce_grammar_tables): Likewise.
10570 * src/gram.c (grammar_dump): Change name of item_number *
10571 local var from r to rp.
10572 * src/nullable.c (nullable_compute): Likewise.
10574 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
10576 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
10577 for symbol or symbol_number var.
10578 * src/reader.c (grammar_start_symbol_set): Likewise.
10579 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
10581 * src/state.c (transitions_to): Likewise.
10582 * src/state.h: Likewise.
10583 * src/tables.c (symbol_number_to_vector_number): Likewise.
10585 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
10588 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
10591 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
10594 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
10595 Use str, not s, for char * var. Use ch, not c, for character var.
10596 Use size for size var.
10598 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
10600 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
10602 * src/uniqstr.h: Likewise.
10604 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
10605 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
10606 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
10607 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
10608 param to have same name as that of enum, so that we don't use
10609 "s" to stand for a non-state.
10611 2003-02-02 Akim Demaille <akim@epita.fr>
10613 * src/scan-skel.l: Scan more than one inert character per yylex
10616 2003-02-01 Paul Eggert <eggert@twinsun.com>
10620 * po/LINGUAS: Add ms.
10622 2003-01-30 Akim Demaille <akim@epita.fr>
10624 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
10626 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10628 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
10631 Changes in response to error report by S. Eken: GLR mode does not
10632 handle negative $ indices or $ indices in embedded rules correctly.
10633 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
10635 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
10636 (b4_rhs_location): Ditto.
10637 (yyfill): New function to copy from stack tree into array
10639 (yyuserAction): Modify to allow incremental move of semantic values
10640 to rhs array when in GLR mode.
10641 Define YYFILL to use in user-defined actions to fill semantic array
10643 Remove dummy use of yystack, as there is now a guaranteed use.
10644 (yydoAction): Modify to allow incremental move of semantic values
10645 to rhs array when in GLR mode.
10646 (yyresolveAction): Ditto.
10647 (yyglrShiftDefer): Update comment.
10648 (yyresolveStates): Use X == NULL for pointers, not !X.
10649 (yyglrReduce): Ditto.
10650 (yydoAction): Ditto
10652 * tests/glr-regr1.at: Rename to ...
10653 * tests/glr-regression.at: Add new regression test for the problems
10654 described above (adapted from S. Eken).
10655 Update copyright notice.
10656 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
10657 * tests/Makefile.am: Ditto.
10659 2003-01-28 Paul Eggert <eggert@twinsun.com>
10661 * data/lalr1.cc: Do not use @output_header_name@ unless
10662 b4_defines_flag is set. This fixes two bugs reported by
10664 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
10665 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
10667 2003-01-21 Paul Eggert <eggert@twinsun.com>
10669 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
10670 we don't need to worry about yyerrlab1 being reported as an
10671 "unused label" by non-GCC C compilers. The downside is that if
10672 locations are used then a couple of statements are duplicated each
10673 time YYERROR is invoked, but the upside is that the warnings
10675 (yyerrlab1): Move code to YERROR.
10676 (yyerrlab2): Remove. Change uses back to yyerrlab1.
10677 This reverts some of the 2002-12-27 change.
10679 2003-01-17 Paul Eggert <eggert@twinsun.com>
10681 * src/output.c (symbol_printers_output): Fix typo that led
10682 to core dump. Problem reported by Antonio Rus in
10683 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
10685 2003-01-13 Akim Demaille <akim@epita.fr>,
10686 Quoc Peyrot <chojin@lrde.epita.fr>,
10687 Robert Anisko <anisko_r@lrde.epita.fr>
10689 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
10690 when the stacks contain one element, as the loop would otherwise
10691 free the last state, and then use the top state (the one we just
10692 popped). This means that the initial elements will not be freed
10693 explicitly, as is the case in yacc.c; it is not a problem, as
10694 these elements have fake values.
10696 2003-01-11 Paul Eggert <eggert@twinsun.com>
10698 * NEWS: %expect-violations are now just warnings, reverting
10699 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
10700 bootstrapping problem reported by Matthias Klose; see
10701 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
10702 * src/conflicts.c (conflicts_print): Likewise.
10703 * tests/conflicts.at (%expect not enough, %expect too much,
10704 %expect with reduce conflicts): Likewise.
10705 * doc/bison.texinfo (Expect Decl): Document this. Also mention
10706 that the warning is enabled if the number of conflicts changes
10707 (not necessarily increases).
10709 * src/getargs.c (version): Update copyright year.
10711 2003-01-09 Akim Demaille <akim@epita.fr>
10713 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
10715 2003-01-08 Paul Eggert <eggert@twinsun.com>
10717 * Makefile.maint (WGETFLAGS):
10718 New macro, containing "-C off" to disable proxy caches.
10719 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
10720 (rel-check): Use $(WGET) instead of wget.
10722 2003-01-06 Paul Eggert <eggert@twinsun.com>
10724 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
10725 the GLR paper of Scott, Johnstone and Hussain.
10727 2003-01-04 Paul Eggert <eggert@twinsun.com>
10729 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
10730 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
10731 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
10732 (EXTRA_LIBRARIES): New var, for liby.a.
10733 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
10734 (EXTRA_SCRIPTS): New var, for yacc.
10736 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
10737 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
10738 Problem reported by Nelson H. F. Beebe.
10740 2003-01-03 Paul Eggert <eggert@twinsun.com>
10742 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
10743 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
10744 when compiling Bison 1.875's `bitset bset = obstack_alloc
10745 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
10747 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
10748 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
10749 grow to a huge size with typical invocation.
10751 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
10752 Use the pattern recommended by Autoconf 2.57, except also protect
10753 against double-definition.
10754 * src/system.h: Likewise.
10755 Portability issues reported by Nelson H. F. Beebe.
10757 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
10758 All uses changed. Provide a definition in both C and C++.
10759 (yytrue, yyfalse): Define even if defined (__cplusplus).
10761 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
10762 Reported by Nelson H. F. Beebe.
10764 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
10766 2003-01-02 Paul Eggert <eggert@twinsun.com>
10768 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
10769 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
10770 Bug reported by Nelson H. F. Beebe.
10772 2003-01-01 Paul Eggert <eggert@twinsun.com>
10776 2002-12-30 Paul Eggert <eggert@twinsun.com>
10778 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
10780 (<INITIAL>","): Here. This causes stray "," to be treated
10783 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
10784 last brace in braced code when not in Yacc mode, for compatibility
10785 with Bison 1.35. This resurrects the 2001-12-15 patch to
10788 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
10789 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
10791 2002-12-28 Paul Eggert <eggert@twinsun.com>
10793 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
10794 that of SYM's type. This fixes Debian bug 168069, reported by
10797 2002-12-28 Paul Eggert <eggert@twinsun.com>
10801 Switch back to the Yacc style of conflict reports, undoing some
10802 of the 2002-07-30 change.
10803 * doc/bison.texinfo (Understanding): Use Yacc style for
10804 conflict reports. Also, use new way of locating rules.
10805 * src/conflicts.c (conflict_report):
10806 Renamed from conflict_report_yacc, removing the old
10807 'conflict_report'. Translate the entire conflict report at once,
10808 so that we don't assume that "," has the same interpretation in
10810 (conflicts_output): Use Yacc-style conflict report for each state,
10811 instead of our more-complicated style.
10812 (conflicts_print): Use Yacc-style conflict report, except print
10813 the input file name when not emulating Yacc.
10814 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
10815 Conflicted Reduction, %expect not enough, %expect too much,
10816 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
10817 * tests/existing.at (GNU Cim Grammar): Likewise.
10818 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
10820 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
10821 fatal): Don't invoke fflush; it's not needed and it might even be
10822 harmful for stdout, as stdout might not be open.
10823 * src/reduce.c (reduce_print): Likewise.
10825 2002-12-27 Paul Eggert <eggert@twinsun.com>
10827 Fix a bug where error locations were not being recorded correctly.
10828 This problem was originally reported by Paul Hilfinger in
10829 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
10831 * data/yacc.c (yyparse): New local var yylerrsp, to record the
10832 top of the location stack's error locations.
10833 (yyerrlab): Set it. When discarding a token, push its location
10834 onto yylerrsp so that we don't lose track of the error's end.
10835 (yyerrlab1): Now is only the target of YYERROR, so that we can
10836 properly record the location of the action that failed. For GCC
10837 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
10838 GCC warning about yyerrlab1 being unused if YYERROR is unused.
10839 (yyerrlab2): New label, which yyerrlab now falls through to.
10840 Compute the error's location by applying YYLLOC_DEFAULT to
10841 the locations of all the symbols that went into the error.
10842 * doc/bison.texinfo (Location Default Action): Mention that
10843 YYLLOC_DEFAULT is also invoked for syntax errors.
10844 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10845 Error locations include the locations of all the tokens that were
10846 discarded, not just the last token.
10848 2002-12-26 Paul Eggert <eggert@twinsun.com>
10850 * src/files.c: Include quote.h.
10851 (compute_output_file_names): Warn if we detect conflicting
10852 outputs to the same file. This should catch the misunderstanding
10853 exemplified by Debian Bug 165349, reported by Bruce Stephens..
10855 * src/conflicts.c (conflicts_print): If the user specifies
10856 "%expect N", report an error if there are any reduce/reduce
10857 conflicts. This is what the manual says should happen.
10858 This fixes Debian bug 130890, reported by Anthony DeRobertis.
10859 * tests/conflicts.at (%expect with reduce conflicts): New test.
10861 Don't use m4_include on relative file names, as it doesn't work as
10862 desired if there happens to be a file with that name under ".".
10864 * m4sugar/version.m4: Remove; it was included but it wasn't used.
10865 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
10866 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
10867 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
10868 * src/output.c (output_skeleton): Use full path names when
10869 specifying a file to include; don't rely on include path, as
10870 it's unreliable when the working file contains a file with
10873 2002-12-25 Paul Eggert <eggert@twinsun.com>
10875 Remove obsolete references to bison.simple and bison.hairy.
10876 Problem mentioned by Aubin Mahe in
10877 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
10878 * data/glr.c: Comment fix.
10879 * doc/bison.1: Remove references. Also, mention "yacc".
10881 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
10884 * src/parse-gram.y (declaration): Use enum "report_states" rather
10885 than its numeric value 1.
10887 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
10888 opening a new one. This fixes Debian bug 165349, reported by
10891 2002-12-24 Paul Eggert <eggert@twinsun.com>
10895 * Makefile.maint (cvs-update): Don't assume that the shell
10896 supports $(...), as Solaris sh doesn't.
10898 * src/parse-gram.y (lloc_default): Remove test for empty
10899 nonterminals at the end, since it didn't change the result.
10901 2002-12-24 Paul Eggert <eggert@twinsun.com>
10903 If the user does not define YYSTYPE as a macro, Bison now declares it
10904 using typedef instead of defining it as a macro. POSIX requires this.
10905 For consistency, YYLTYPE is also declared instead of defined.
10907 %union directives can now have a tag before the `{', e.g., the
10908 directive `%union foo {...}' now generates the C code
10909 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
10910 The default union tag is `YYSTYPE', for compatibility with Solaris 9
10911 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
10912 instead of `yyltype'.
10914 `yystype' and `yyltype' are now obsolescent macros instead of being
10915 typedefs or tags; they are no longer documented and will be
10916 withdrawn in a future release.
10918 * data/glr.c (b4_location_type): Remove.
10919 (YYSTYPE): Renamed from yystype.
10920 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
10921 (struct YYLTYPE): Renamed from struct yyltype.
10922 (YYLTYPE): Renamed from yyltype.
10923 (yyltype, yystype): New (and obsolescent) macros,
10924 for backward compatibility.
10925 * data/yacc.c: Likewise.
10927 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
10928 does not specify a union tag. This is for compatibility with
10931 * src/parse-gram.y (add_param): 2nd arg is now char * not char
10932 const *, since it is now modified by stripping surrounding { }.
10933 (current_braced_code): Remove.
10934 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
10935 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
10936 trailing " {...}". Now of type <chars>.
10937 (grammar_declaration): Adjust to bundled tokens.
10938 (code_content): Remove; stripping is now done by add_param.
10939 (print_token_value): Print contents of bundled tokens.
10940 (token_name): New function.
10942 * src/reader.h (braced_code, current_braced_code): Remove.
10943 (token_name): New decl.
10945 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
10946 token_type, not braced_code code_kind. All uses changed.
10947 (SC_PRE_CODE): New state, for scanning after a keyword that
10948 has (or usually has) an immediately-following braced code.
10949 (token_type): New local var, to keep track of which token type
10950 to return when scanning braced code.
10951 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
10952 <INITIAL>"%parse-param", <INITIAL>"%printer",
10953 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
10954 instead of returning a token type immediately.
10955 (<INITIAL>"{"): Set token type.
10956 (<SC_BRACED_CODE>"}"): Use it.
10957 (handle_action_dollar, handle_action_at): Now returns bool
10958 indicating success. Fail if ! current_rule; this prevents a core dump.
10959 (handle_symbol_code_dollar, handle_symbol_code_at):
10960 Remove; merge body into caller.
10961 (handle_dollar, handle_at): Complain in invalid contexts.

10964 * NEWS: Fix years and program names in copyright notice.
10966 2002-12-17 Paul Eggert <eggert@twinsun.com>
10968 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
10969 Reporting, Table of Symbols): Omit mentions of %lex-param and
10970 %parse-param from the documentation for now.
10972 2002-12-15 Paul Eggert <eggert@twinsun.com>
10974 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
10975 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
10976 lookahead symbol, and which sets yychar in parser actions) and it
10977 disagreed with the Bison documentation. Bug
10978 reported by Andrew Walrond.
10980 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
10981 as the caller now does that.
10982 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
10983 (YYEMPTY): Parenthesize right hand side, since others use it.
10984 (yyparse): Don't assume that our generated code is the only code
10987 2002-12-13 Paul Eggert <eggert@twinsun.com>
10991 POSIX requires a "yacc" command.
10992 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
10993 (MOSTLYCLEANFILES): Add yacc.
10995 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
10996 as an alias for bison y.
10998 * po/LINGUAS: Add da.
11000 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
11001 problem with latest <getopt.h>.
11002 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
11004 * doc/fdl.texi: Upgrade to 1.2.
11005 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
11006 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
11007 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
11009 * config/install-sh: Sync with autotools.
11011 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
11012 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
11013 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
11014 locations are requested.
11015 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
11016 locations are requested.
11018 2002-12-12 Paul Eggert <eggert@twinsun.com>
11020 Remove unportable casts and storage allocation tricks.
11021 While we're at it, remove almost all casts, since they
11022 usually aren't needed and are a sign of trouble.
11024 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
11026 * src/derives.c (derives_compute): Do not subtract NTOKENS from
11027 the pointer DSET returned by malloc; this isn't portable.

11029 Similarly for DERIVES.
11030 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
11031 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.

11055 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
11058 * src/muscle_tab.c (muscle_m4_output):
11059 Now inline. Return bool, not int.
11060 * src/state.c (state_compare): Likewise.
11061 * src/symtab.c (symbol_check_defined,
11062 symbol_check_alias_consistency, symbol_pack, symbol_translation,

11070 symbol_check_alias_consistency_processor, symbol_pack_processor,
11071 symbol_translation_processor, hash_symbol_comparator,
11072 hash_symbol_hasher): Likewise.
11073 * src/uniqstr.c (uniqstr_print_processor): Likewise.
11074 * src/muscle_tab.c (muscles_m4_output):
11075 Use new functions instead of casting old functions unportably.
11076 * src/state.c (state_hash_new): Likewise.
11077 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
11078 symbols_token_translations_init):
11080 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
11082 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
11083 var instead of casting to long, to avoid casts.
11084 (prepare_states): Use MALLOC rather than alloca, so that we don't
11085 have to worry about alloca.
11086 * src/state.c (state_hash_lookup): Likewise.
11088 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
11089 local var instead of casting to unsigned char, to avoid casts.
11091 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
11092 STATE_ALLOC): Remove.
11093 (transitions_new, errs_new, reductions_new, state_new): Use malloc
11094 rather than calloc, and use offsetof to avoid allocating slightly
11096 (state_new): Initialize all members.
11098 * src/state.c (state_hash): Use unsigned accumulator, not signed.
11100 * src/symtab.c (symbol_free): Remove; unused.
11101 (symbol_get): Remove cast in lhs of assignment.

11103 hashing-related ones.
11105 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
11106 (symbol_processor): Remove.
11107 (symbols_do): Remove decl; now static.
11109 * src/system.h (alloca): Remove; decl no longer needed.
11110 (<stddef.h>): Include, for offsetof.
11111 (<inttypes.>, <stdint.h>): Include if available.
11112 (uintptr_t): New type, if system lacks it.
11113 (CALLOC, MALLOC, REALLOC): New macros.
11114 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these

11130 2002-12-09 Paul Eggert <eggert@twinsun.com>
11132 Change identifier spellings to avoid collisions with names
11133 that are reserved by POSIX.
11135 Don't use names ending in _t, since POSIX reserves them.
11136 For consistency, remove _e and _s endings -- they're weren't
11137 needed to remove ambiguity. All uses changed.
11138 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
11139 turn was just renamed from struniq_t.
11140 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
11141 which in turn was just renamed from struniq_processor_t.
11142 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

11213 value_t_as_yystype -> value_as_yystype.
11215 Don't include <errno.h> in the mainstream code, since it
11216 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
11217 * lib/get-errno.c, lib/get-errno.h: New files.
11218 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

11228 (TAB_EXT): Renamed from EXT_TAB.

11233 likewise for "STRUNIQ" and "UNIQSTR".
11234 * src/uniqstr.c: Renamed from src/struniq.c.
11235 * src/uniqstr.h: Renamed from src/struniq.h.

11246 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.

11273 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
11276 Sort include-file uses.
11278 Reorder all include files under src to be in the order "system.h".
11279 then the ../lib include files in angle brackets (alphabetized),
11280 then the . include files in double-quotes (alphabetized). Fix
11281 dependency breakages encountered in this process, as follows:
11282 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
11283 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
11284 * src/state.h: Include "symtab.h".
11286 2002-12-08 Paul Eggert <eggert@twinsun.com>
11288 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
11289 since this causes problems when __file__ contains character
11290 sequences like "@" that are treated specially by src/scan-skel.l.
11291 Instead, just use the file's basename. This fixes the bug
11292 reported by Martin Mokrejs in
11293 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
11295 2002-12-06 Paul Eggert <eggert@twinsun.com>
11297 Add support for rules that do not have trailing semicolons, as

11301 * src/location.c: Include <quotearg.h>.
11302 (empty_location): Now const.
11303 (location_print): New function. Follow the recommendation of the

11305 * src/location.h: Do not include <quotearg.h>; no longer needed.
11306 (boundary): New type.
11307 (location_t): Use it. This allows locations to span file boundaries.
11308 All member uses changed: file -> start.file or end.file (as needed),
11309 first_line -> start.line, first_column -> start.column,
11310 last_line -> end.line, last_column -> end.column.
11311 (equal_boundaries): New function.
11312 (LOCATION_RESET, LOCATION_STEP): Remove.
11313 (LOCATION_PRINT): Remove. All callers changed to use location_print.
11314 (empty_location): Now const.
11315 (location_print): New decl.
11316 * src/parse-gram.y (lloc_default): New function, which handles
11317 empty locations more accurately.
11318 (YYLLOC_DEFAULT): Use it.
11319 (%token COLON): Remove.
11320 (%token ID_COLON): New token.

11328 * src/reader.h: Include location.h.
11329 (scanner_cursor): New decl.

11332 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
11334 (STEP): Remove. No longer needed, now that adjust_location does
11335 the work. All uses removed.
11336 (scanner_cursor): New var.
11337 (adjust_location): Renamed from extend_location. It now sets
11338 *loc and adjusts the scanner cursor. All uses changed.
11339 Don't bother testing for CR.
11340 (handle_syncline): Remove location arg; now updates scanner cursor.
11341 All callers changed.
11342 (unexpected_end_of_file): Now accepts start boundary of token or
11343 comment, not location. All callers changed. Update scanner cursor,
11345 (SC_AFTER_IDENTIFIER): New state.
11346 (context_state): Renamed from c_context. All uses changed.
11347 (id_loc, code_start, token_start): New local vars.
11348 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
11349 processing of Yacc white space and equivalents here.
11350 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
11351 instead of returning ID immediately, since we need to search for
11352 a subsequent colon.
11353 (<INITIAL>"'", "\""): Save token_start.
11354 (<INITIAL>"%{", "{", "%%"): Save code_start.
11355 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
11356 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
11357 BEGIN context_state at end, not INITIAL.
11358 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
11359 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
11360 Return correct token start.
11361 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
11362 the start of a character, string or multiline comment is found.
11363 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
11364 Reduction): Adjust reported locations to match the more-precise
11365 results now expected.
11366 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
11367 * tests/reduce.at (Useless Rules, Reduced Automaton,
11368 Underivable Rules): Likewise.
11369 * tests/regression.at (Invalid inputs): No longer `expecting ";"
11370 or "|"' now that so many other tokens are allowed by the new grammar.
11372 * src/complain.h (current_file): Remove duplicate decl;
11373 current_file is now owned by files.h.
11374 * src/complain.c, src/scan-gram.l: Include files.h.
11376 2002-12-06 Paul Eggert <eggert@twinsun.com>
11378 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
11379 promotes to int; it might be unsigned int.
11380 * data/yacc.c (yy_reduce_print): Likewise.
11382 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
11383 be #defined in the prologue, not in the Bison declarations.
11384 This fixes Debian Bug 102878, reported by Shaul Karl.
11386 2002-12-02 Paul Eggert <eggert@twinsun.com>
11388 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
11389 * lib/strtoul.c: New file, from gnulib.
11390 This fixes a porting bug reported by Peter Klein in
11391 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
11393 2002-11-30 Paul Eggert <eggert@twinsun.com>
11395 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
11396 and put only a forward declaration in the prologue. This is for
11397 consistency with the other scanner helper functions.
11399 Type clashes now generate warnings, not errors, since it
11400 appears that POSIX may allow some grammars with type clashes.
11401 * src/reader.c (grammar_current_rule_check): Warn about
11402 type clashes instead of complaining.
11403 * tests/input.at (Type Clashes): Expect warnings, not complaints.
11405 Add Yacc library, since POSIX requires it.
11406 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
11407 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
11408 * lib/main.c, lib/yyerror.c: New files.
11410 gram_error can be static; it need not be extern.
11411 * src/reader.h (gram_error): Remove decl.
11412 * src/parse-gram.y (gram_error): Now static. Add static decl.
11413 (print_token_value): Omit parameter names from forward decl,
11416 2002-11-29 Paul Eggert <eggert@twinsun.com>
11418 * doc/bison.texinfo: Emphasize that yylex and yyerror must
11419 be declared before being used. E.g., one should typically
11420 declare them in the prologue. Use GNU coding style in examples.
11421 Put "const" consistently after the type it modifies. Mention
11422 that C99 supports "inline". Mention that yyerror traditionally
11425 %parse-param and %lex-param now take just one argument, the
11426 declaration; the argument name is deduced from the declaration.
11428 * doc/bison.texinfo (Parser Function, Pure Calling, Error
11429 Reporting, Table of Symbols): Document this.
11430 * src/parse-gram.y (add_param): New function.
11432 (declaration): Implement new rule for %parse-param and %lex-param.
11433 * src/scan-gram.l: "," now elicits a warning, rather than being
11434 a token; this is more compatible with byacc.
11435 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
11437 2002-11-27 Paul Eggert <eggert@twinsun.com>
11439 Rename identifiers to avoid real and potential collisions.
11441 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
11442 to avoid collision with lex macro described by Bruce Lilly in
11443 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
11444 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
11445 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
11446 * src/parse-gram.y (print_token_value): Renamed from yyprint.
11448 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
11449 The name "yycontrol" violates the name space rules, and this stuff
11450 wasn't being used anyway.
11451 (input): Remove action; this stuff wasn't being used.
11452 (gram_error): Rename local variable yylloc -> loc.
11453 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
11454 (YY_DECL): Don't use "yy" at start of local variables.
11455 All uses changed, e.g., yylloc -> loc.
11456 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
11457 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
11458 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
11459 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
11461 * src/parse-gram.y (gram_error): loc is now const *.
11462 * src/reader.h (gram_error): Likewise.
11464 2002-11-24 Paul Eggert <eggert@twinsun.com>
11468 * tests/actions.at (Actions after errors): Use an output format
11469 more similar to that of the Printers and Destructors test.
11470 Test the position of the ';' token too.
11471 (Printers and Destructors): Likewise.
11472 (Printers and Destructors: %glr-parser): Remove for now, to avoid
11473 unnecessarily alarming people when the test fails.
11475 * data/yacc.c (yyerrlab1): Move this label down, so that the
11476 parser does not discard the lookahead token if the user code
11477 invokes YYERROR. This change is required for POSIX conformance.
11479 * lib/error.c: Sync with gnulib.
11481 2002-11-22 Paul Eggert <eggert@twinsun.com>
11483 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
11484 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
11485 * lib/xmalloc.c: Likewise.
11487 2002-11-20 Paul Eggert <eggert@twinsun.com>
11489 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
11491 2002-11-20 Paul Eggert <eggert@twinsun.com>
11493 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
11494 should use `if (! x) abort ();' rather than `assert (x);', and
11495 anyway it's one less thing to worry about configuring.
11497 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
11498 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
11499 and replace all instances of assert with abort.
11500 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
11501 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
11503 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
11504 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
11505 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
11506 hash_find_entry, hash_rehash, hash_insert): Likewise.
11507 * src/conflicts.c (resolve_sr_conflict): Likewise.
11508 * src/lalr.c (set_goto_map, map_goto): Likewise.
11509 * src/nullable.c (nullable_compute): Likewise.
11510 * src/output.c (prepare_rules, token_definitions_output): Likewise.
11511 * src/reader.c (packgram, reader): Likewise.
11512 * src/state.c (state_new, state_free, state_transitions_set,
11513 state_reduction_find): Likewise.
11514 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
11515 symbol_pack): Likewise.
11516 * src/tables.c (conflict_row, pack_vector): Likewise.
11517 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
11518 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
11519 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
11520 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
11522 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
11523 (ARGMATCH_CONSTRAINT): New macro.
11524 (ARGMATCH_ASSERT): Use it.
11526 * src/system.h (verify): New macro.
11527 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
11528 rather than assert.
11529 * src/tables.c (tables_generate): Likewise.
11531 * src/struniq.c (struniq_assert): Now returns void, and aborts
11532 if the assertion is false.
11533 (struniq_assert_p): Remove.
11534 * src/struniq.h: Likewise.
11536 2002-11-18 Paul Eggert <eggert@twinsun.com>
11538 * data/glr.c (yygetLRActions): Replace `yyindex' with
11539 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
11540 This fixes the regression with Sun ONE Studio 7 cc that I reported in
11541 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
11543 2002-11-18 Akim Demaille <akim@epita.fr>
11545 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
11547 From Tim Van Holder.
11549 2002-11-17 Paul Eggert <eggert@twinsun.com>
11551 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
11552 to "SyntaxError" for consistency with my 2002-11-15 change.
11554 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
11555 not define to {}, since this breaks the common use of `YYDPRINTF
11556 ((...));' if a single statement is desired (e.g. before `else').
11557 Work around GCC warnings by surrounding corresponding calls with
11559 (yyhasResolvedValue): Remove unused function.
11560 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
11562 (yyreportSyntaxError): Renamed from yyreportParseError.
11563 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
11565 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
11566 extern when possible. Remove unused initializations.
11568 2002-11-16 Akim Demaille <akim@epita.fr>
11570 Augment the similarity between GLR and LALR traces.
11572 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
11573 (YY_REDUCE_PRINT): New.
11574 (yyparse): Use them.
11575 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
11577 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
11578 state reached after the reduction/recovery, since...
11579 (yyparse, yyprocessOneStack): Report the state we are entering in.
11581 2002-11-16 Akim Demaille <akim@epita.fr>
11583 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
11584 Add support for --trace=skeleton.
11585 * src/scan-skel.l: %option debug.
11586 Scan strings of non-@ or \n instead of character by character.
11587 (scan_skel): Handle trace_skeleton.
11589 (@output_parser_name@, @output_header_name@): ``Restore'' their
11590 support (used to be M4 macros).
11591 * data/yacc.c: Quote larger chunks, a la glr.c.
11592 * data/lalr1.cc: Likewise.
11593 The header guards are no longer available, so use some other
11594 string than `YYLSP_NEEDED'.
11596 2002-11-16 Akim Demaille <akim@epita.fr>
11598 Make the ``Printers and Destructors'' test more verbose, taking
11599 `yacc.c''s behavior as (possibly wrong) reference.
11601 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
11602 instead of fprint on stdout.
11603 Set and report the last_line of the symbols.
11604 Consistently display values and locations.
11606 2002-11-16 Paul Eggert <eggert@twinsun.com>
11608 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
11610 2002-11-15 Paul Eggert <eggert@twinsun.com>
11612 * tests/actions.at (Actions after errors): New test case.
11614 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
11615 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
11616 tests/action.at, tests/calc.at, tests/conflicts.at,
11617 tests/cxx-type.at, tests/regression.at:
11618 "parse error" -> "syntax error" for POSIX compatibility.
11619 "parsing stack overflow..." -> "parser stack overflow" so
11620 that code matches Bison documentation.
11622 2002-11-15 Akim Demaille <akim@epita.fr>
11624 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
11625 take two BRACED_CODE, not two string_content.
11626 Free the scanner's obstack when we are done.
11627 (code_content): New.
11628 * tests/calc.at: Adjust.
11629 * doc/bison.texinfo: Adjust.
11630 Also, make sure to include the `,' for these declarations.
11632 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
11634 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
11635 definition; avoids potential autoreconf problems.
11637 2002-11-15 Akim Demaille <akim@epita.fr>
11639 Always check the value returned by yyparse.
11641 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
11642 returned by yyparse.
11643 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
11645 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
11646 returned by yyparse.
11648 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11650 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
11653 2002-11-14 Paul Eggert <eggert@twinsun.com>
11655 * src/output.c (output_skeleton): Call xfopen instead of
11656 duplicating xfopen's body.
11658 Fix bugs reported by Nelson H. F. Beebe in
11659 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
11661 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
11662 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
11663 Group compiler. Instead, use "$CC -E bar.c". Include the .h
11664 file twice in the grammar, as an extra check.
11666 * tests/input.at (Torturing the Scanner): Surround the
11667 backslash-newline tests with "#if 0", to make it less likely that
11668 we'll run into compiler bugs. Bring back solitary \ inside
11669 comment, but add a closing comment to work around HP C bug. Don't
11670 test backslash-newline in C character constant.
11672 2002-11-14 Akim Demaille <akim@epita.fr>
11674 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
11675 status of the compiler.
11676 Calling `exit 1' is no longer needed.
11677 Reported by Nelson H. F. Beebe.
11679 2002-11-14 Akim Demaille <akim@epita.fr>
11681 * tests/atlocal.in (CPPFLAGS): We have config.h.
11682 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
11684 * tests/actions.at, tests/calc.at, tests/conflicts.at,
11685 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
11686 * tests/regression.at, tests/torture.at: Use them for all the
11687 grammars that are to be compiled.
11688 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
11689 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
11690 * doc/bison.texinfo (GLR Parsers): Document `inline'.
11692 2002-11-14 Akim Demaille <akim@epita.fr>
11694 * doc/bison.texinfo: Various formatting changes (alignments in
11695 samples, additional @group/@end group, GCS in samples.
11696 Use @deffn instead of simple @table to define the directives,
11697 macros, variables etc.
11699 2002-11-13 Paul Eggert <eggert@twinsun.com>
11701 Fix some bugs reported by Albert Chin-A-Young in
11702 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
11704 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
11705 -o c"; the HP C compiler chatters during compilation.
11706 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
11707 * tests/headers.at (export YYLTYPE): Likewise.
11709 * tests/input.at (Torturing the Scanner): Remove lines containing
11710 solitary backslashes, as they tickle a bug in the HP C compiler.
11712 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
11713 comments, since they're not portable. Use GNU coding style.
11715 2002-11-13 Akim Demaille <akim@epita.fr>
11717 * data/yacc.c: Leave bigger chunks of quoted text.
11718 (YYDSYMPRINTF): New.
11719 Use it to report symbol activities.
11720 * data/glr.c (YYDSYMPRINTF): New.
11723 2002-11-12 Paul Eggert <eggert@twinsun.com>
11727 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
11728 (yyglrReduce): Return yyok, not 0.
11729 This should avoid the enumerated-type warnings reported
11730 by Nelson H. F. Beebe in
11731 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
11733 * lib/bbitset.h (BITSET_INLINE): Remove.
11734 * lib/bitset.h [! BITSET_INLINE]: Remove.
11735 (bitset_set, bitset_reset, bitset_test): Rename local vars
11736 to avoid shadowing warnings by GCC.
11738 * data/glr.c (inline): Remove #define. It's the user's
11739 responsibility to #define it away, just like 'const'.
11740 This fixes one of the bugs reported by Nelson H. F. Beebe in
11741 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
11743 * Makefile.maint (po-check): Scan .l and .y files instead of the
11744 .c and the .h files that they generate. This fixes the bug
11745 reported by Tim Van Holder in:
11746 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
11747 Look for N_ as well as for _. Try to avoid matching #define for
11749 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
11750 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
11751 * src/scan-gram.l: Revamp regular expressions so that " and '
11752 do not confuse xgettext.
11754 * src/struniq.h (struniq_new): Do not declare the return type
11755 to be 'const'; this violates the C standard.
11756 * src/struniq.c (struniq_new): Likewise.
11758 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
11760 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
11761 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
11764 2002-11-12 Akim Demaille <akim@epita.fr>
11766 * Makefile.maint: Sync with Autoconf:
11767 (local_updates): New.
11769 2002-11-12 Akim Demaille <akim@epita.fr>
11771 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
11773 2002-11-12 Akim Demaille <akim@epita.fr>
11775 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
11778 2002-11-12 Akim Demaille <akim@epita.fr>
11780 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
11783 2002-11-12 Akim Demaille <akim@epita.fr>
11785 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
11786 Use it to test the GLR parser.
11788 2002-11-12 Akim Demaille <akim@epita.fr>
11790 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
11792 * data/glr.c (yystos): New.
11793 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
11794 (YYDSYMPRINT): New.
11795 (yyval): Don't define it, it is handled via M4.
11796 (yyrecoverParseError): Free verbosely the discarded symbols.
11797 * data/yacc.c (yysymprint): Remove, rather...
11798 (b4_yysymprint_generate): invoke.
11799 * data/c.m4 (b4_yysymprint_generate): New.
11800 Accept pointers as arguments, as opposed to the version from
11802 (b4_yydestruct_generate): Likewise.
11803 * tests/cations.at (Printers and Destructors): Use Bison directives
11804 instead of CPP macros.
11805 Don't rely on internal details.
11807 2002-11-12 Akim Demaille <akim@epita.fr>
11809 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
11810 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
11811 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
11812 it against YYEMPTY and so forth), work on yytoken (i.e., set
11813 it to YYEMPTY etc.).
11814 (yydestruct): Replace with a b4_yydestruct_generate invocation.
11815 (b4_symbol_actions): Remove.
11816 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
11817 for 0, end-of-input.
11819 2002-11-12 Akim Demaille <akim@epita.fr>
11821 * doc/bison.texinfo (Destructor Decl): New.
11823 2002-11-12 Akim Demaille <akim@epita.fr>
11825 * src/tables.c (tables_generate): Use free for pointers that
11826 cannot be NULL, not XFREE.
11827 (pack_vector): Use assert, not fatal, for bound violations.
11828 * src/state.c (state_new): Likewise.
11829 * src/reader.c (reader): Likewise.
11830 * src/lalr.c (set_goto_map): Likewise.
11831 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
11834 2002-11-12 Akim Demaille <akim@epita.fr>
11836 * src/scan-gram.l, src/reader.h (scanner_last_string_free):

11902 2002-11-11 Paul Eggert <eggert@twinsun.com>
11904 Revamp to fix many (but not all) of the C- and M4-related quoting
11905 problems. Among other things, this fixes the Bison bug reported
11906 by Jan Hubicka when processing the Bash grammar; see:
11907 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
11909 Use new @ escapes consistently. Represent brackets with @{ and @}
11910 rather than @<:@ and @:>@, since this works a bit better with dumb
11911 editors like vi. Represent @ with @@, since @ is now consistently
11912 an escape. Use @oline@ and @ofile@ rather than __oline__ and
11913 __ofile__, to avoid unexpected expansions. Similarly, use @output
11914 rather than #output.
11916 * data/c.m4 (b4_copyright): Omit file name from comment, since
11917 the file name could contain "*/".
11918 (b4_synclines_flag): Don't quote the 2nd argument; it should already
11919 be quoted. All uses changed.
11921 * data/glr.c: Use new @ escapes consistently.
11922 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
11923 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
11924 Remove, since they couldn't handle arbitrary characters in file
11926 * data/lalr1.cc: Likewise.
11927 * data/yacc.c: Likewise.
11929 * src/files.c (output_infix): Remove; all uses removed.
11930 * src/files.h: Likewise.
11932 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
11933 mishandled funny characters in file names, and anyway it isn't
11935 * data/yacc.c: Likewise.
11936 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
11938 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
11939 * data/yacc.c: Likewise.
11941 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
11943 (muscle_init): Quote filename as a C string.
11944 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
11945 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
11946 * src/output.c (escaped_file_name_output): New function.
11947 (prepare_symbols): Quote tokens for M4.
11948 (prepare): Don't insert output_infix, output_prefix,
11949 output_parser_name, output_header_name; this is now down by scan-skel.
11950 Insert skeleton as a C string.
11952 * src/output.c (user_actions_output, symbol_destructors_output,
11953 symbol_printers_output): Quote filenames for C and M4.
11954 * src/reader.c (prologue_augment, epilogue_set): Likewise.
11956 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
11957 escapes other than \\ and \'; this simplifies the code.
11958 (<SC_STRING>): Likewise, for \\ and \".
11959 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
11960 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
11961 Use new escapes @{ and @} for [ and ].
11963 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
11964 them with auto vars.
11965 Switch to new escape scheme, where @ is the escape character uniformly.
11966 Abort if a stray escape character is found. Avoid unbounded input
11967 buffer when parsing non-escaped text.
11969 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
11970 __oline__, #output, $@, and @{ do not have unintended meanings.
11972 2002-11-09 Paul Eggert <eggert@twinsun.com>
11974 Fix the test failure due to GCC warnings described in
11975 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
11976 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
11977 evaluate to 0 if it's impossible for NINF to be in the respective
11979 (yygetLRActions, yyrecoverParseError): Use them.
11981 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
11982 counted in the token inserted at end of file. Now takes
11983 location_t *, not location_t, so that the location can be
11984 adjusted. All uses changed.
11986 * tests/regression.at (Invalid inputs): Adjust wording in
11987 diagnostic to match the new behavior.
11989 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
11990 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
11991 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
11992 abort ();'. This reduces the runtime of the "Many lookaheads"
11993 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
11996 2002-11-07 Paul Eggert <eggert@twinsun.com>
11998 * src/parse-gram.y (CHARACTER): Remove unused token.
12001 * src/scan-gram.l: Remove stack option. We no longer use the
12002 stack, since the stack was never deeper than 1; instead, use the
12003 new auto var c_context to record the stacked value.
12005 Remove nounput option. At an unexpected end of file, we now unput
12006 the minimal input necessary to end cleanly; this simplifies the
12009 Avoid unbounded token sizes where this is easy.
12011 (unexpected_end_of_file): New function.
12012 Use it to systematize the error message on unexpected EOF.
12013 (last-string): Now auto, not static.
12014 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
12015 (scanner_last_string_free): Remove; not used.
12016 (percent_percent_count): Move decl to just before use.
12017 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
12018 not the (never otherwised-used) CHARACTER.
12020 2002-11-07 Akim Demaille <akim@epita.fr>

12040 * src/output.c (symbol_printers_output)
12041 (symbol_destructors_output): Quote the file name.

12072 * src/tables.c (matching_state): Don't allow states to match if
12073 either has GLR conflict entries.
12075 2002-11-05 Paul Eggert <eggert@twinsun.com>
12077 * src/scan-gram.l: Use more accurate diagnostics, e.g.
12078 "integer out of range" rather than "invalid value".
12079 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
12082 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
12083 Also, remove one static variable in the scanner.
12085 * src/scan-gram.l (braces_level): Now auto, not static.
12086 Initialize to zero if the compiler is being picky.
12087 (INITIAL): Clear braces_level instead of incrementing it.
12088 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,

12095 * src/scan-gram.l: When it starts with `%', complain about the
12096 whole directive, not just that `invalid character: %'.
12098 2002-11-04 Akim Demaille <akim@epita.fr>
12100 * Makefile.maint: Update from Autoconf.
12101 (update, cvs-update, po-update, do-po-update): New.

12124 * src/reader.c (get_merge_function, grammar_current_rule_check):
12125 Use consistent diagnostics for reporting type name clashes.
12126 Quote the types with <>, for consistency with Yacc.
12127 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
12129 2002-11-03 Akim Demaille <akim@epita.fr>
12131 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):

12143 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
12144 (yyreportAmbiguity): When using a pure parser, also need
12145 the location, and the parse-params.

12152 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
12153 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
12154 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.

12212 with quote slot used by complain_at.
12214 * tests/input.at: Add tests for backslash-newline, m4 quotes

12238 bug in trigraph handling.
12240 * src/output.c (prepare_symbols): When printing token names,
12241 escape "[" as "@<:@" and likewise for "]".
12243 * src/system.h (errno): Remove declaration, as we are now
12244 assuming C89 or better, and C89 guarantees errno.
12246 2002-10-30 Paul Eggert <eggert@twinsun.com>
12248 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
12249 Check for close failures.
12250 * src/files.h (xfclose): Return void, not int, since it always
12252 * src/files.c (xfclose): Likewise. Report I/O error if ferror
12254 * src/output.c (output_skeleton): Use xfclose rather than fclose
12255 and ferror. xfclose now checks ferror.
12257 * data/glr.c (YYLEFTMOST_STATE): Remove.
12258 (yyreportTree): Use a stack-based leftmost state. This avoids
12259 our continuing battles with bogus warnings about initializers.
12261 2002-10-30 Akim Demaille <akim@epita.fr>
12263 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

12276 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
12277 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
12278 we use malloc. Don't assume 'A' through 'Z' are contiguous.
12279 Don't assume strdup exists; POSIX says its an XSI extension.
12280 Check for buffer overflow on input.
12282 2002-10-24 Akim Demaille <akim@epita.fr>
12284 * src/output.c (output_skeleton): Don't disable M4sugar comments
12285 too soon: it results in comments being expanded.

12291 * data/yacc.c (m4_int_type): New.
12292 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
12293 char' as only yacc.c wants K&R portability.
12294 * data/glr.c (yysigned_char): Remove.
12295 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
12296 Reported by Quoc Peyrot.
12298 2002-10-23 Paul Eggert <eggert@twinsun.com>
12300 * src/main.c (main): With --trace=time, report times even if a
12301 non-fatal error occurs. Formerly, the times were reported in some
12302 such cases but not in others.
12303 * src/reader.c (reader): Just return if a complaint has been issued,
12304 instead of exiting, so that 'main' can report times.
12306 2002-10-22 Akim Demaille <akim@epita.fr>
12308 * src/system.h: Include sys/types.
12309 Reported by Bert Deknuydt.
12311 2002-10-23 Paul Eggert <eggert@twinsun.com>
12313 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
12314 Suggested by Art Haas.
12316 2002-10-22 Paul Eggert <eggert@twinsun.com>
12318 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
12319 decl; not needed any more.
12320 * src/main.c (main): Use return to exit, undoing yesterday's change.
12321 The last OS that we could find where this wouldn't work is
12322 SunOS 3.5, and that's too old to worry about now.
12324 * data/glr.c (struct yyltype): Define members even when not
12325 doing locations. This is more consistent with yacc.c, and it
12326 works around the following bug reports:
12327 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
12328 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
12330 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
12331 @acronym consistently. Standardize on "Yacc" instead of "YACC",
12332 "Algol" instead of "ALGOL". Give a bit more history about BNF.
12334 2002-10-22 Akim Demaille <akim@epita.fr>
12336 * data/README: New.
12338 2002-10-21 Paul Eggert <eggert@twinsun.com>
12340 Be consistent about 'bool'; the old code used an enum in one
12341 module and an int in another, and this violates the C standard.
12342 * m4/stdbool.m4: New file, from coreutils 4.5.3.
12343 * configure.ac (AC_HEADER_STDBOOL): Add.
12344 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
12345 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
12346 * src/symtab.c (hash_compare_symbol_t): Likewise.
12347 * src/system.h (bool, false, true): Use a definition consistent
12348 with ../lib/hash.c. All uses changed.
12350 * src/complain.c (warning_issued): Renamed from warn_message_count,
12351 so that we needn't worry about integer overflow (!).
12352 Now of type bool. All uses changed.
12353 (complaint_issued): Renamed from complain_message_count; likewise.
12355 * src/main.c (main): Use exit to exit with failure.
12357 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
12358 rather than 1 and 0.
12359 * src/main.c (main): Likewise.
12360 * src/getargs.c (getargs): Likewise.
12361 * src/reader.c (reader): Likewise.
12363 * src/getarg.c (getargs): Remove duplicate code for
12364 "Try `bison --help'".
12366 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
12367 What was that "2" for?
12369 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
12370 * src/getargs.c (usage): Likewise.
12372 * src/getargs.c (getargs): When there are too few operands, report
12373 the last one. When there are too many, report the first extra
12374 one. This is how diffutils does it.
12376 2002-10-20 Paul Eggert <eggert@twinsun.com>
12378 Remove K&R vestiges.
12379 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
12380 * src/complain.c (VA_START): Remove. Assume prototypes.
12381 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
12382 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
12383 fatal): Assume prototypes.
12384 * src/complain.h: Assume prototypes.
12385 * src/system.h (PARAMS): Remove.
12386 Include <limits.h> unconditionally, since it's guaranteeed even
12387 for a freestanding C89 compiler.
12388 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
12389 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
12391 2002-10-20 Akim Demaille <akim@epita.fr>
12393 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
12394 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
12395 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
12396 (yyresolveStates, yyresolveAction, yyresolveStack)
12397 (yyprocessOneStack): Use them.
12398 (yy_reduce_print): New.
12399 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
12401 2002-10-20 Akim Demaille <akim@epita.fr>
12403 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
12404 arguments and output `void'.
12405 (b4_c_function): Rename as...
12406 (b4_c_function_def): this.
12407 (b4_c_function_decl, b4_c_ansi_function_def)
12408 (b4_c_ansi_function_decl): New.
12409 Change the interpretation of the arguments: before `int, foo', now
12411 * data/yacc.c (yyparse): Prototype and define thanks to these.
12412 Adjust b4_c_function_def uses.
12413 * data/glr.c (yyparse): Likewise, but ANSI only.
12415 2002-10-20 Akim Demaille <akim@epita.fr>
12417 * src/output.c (prepare): Move the definition of `tokens_number',
12418 `nterms_number', `undef_token_number', `user_token_number_max'
12420 (prepare_tokens): Here.
12421 (prepare_tokens): Rename as...
12422 (prepare_symbols): this.
12423 (prepare): Move the definition of `rules_number' to...
12424 (prepare_rules): here.
12425 (prepare): Move the definition of `last', `final_state_number',
12426 `states_number' to...
12427 (prepare_states): here.
12428 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
12430 2002-10-20 Akim Demaille <akim@epita.fr>
12432 * src/tables.h, src/tables.c, src/output.c: Comment changes.
12434 2002-10-20 Akim Demaille <akim@epita.fr>
12436 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
12439 2002-10-20 Akim Demaille <akim@epita.fr>
12441 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
12442 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
12444 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
12446 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
12447 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
12450 2002-10-19 Paul Eggert <eggert@twinsun.com>
12452 Do not create a temporary file, as that involves security and
12453 cleanup headaches. Instead, use a pair of pipes.
12454 Derived from a suggestion by Florian Krohm.
12455 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
12456 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
12457 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
12458 (BISON_PREREQ_SUBPIPE): Add.
12459 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
12460 Add subpipe.h, subpipe.c.
12461 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
12462 * po/POTFILES.in: Add lib/subpipe.c.
12463 * src/output.c: Include "subpipe.h".
12464 (m4_invoke): Remove decl.
12465 (scan_skel): New decl.
12466 (output_skeleton): Use pipe rather than temporary file for m4 input.
12467 Check that m4sugar.m4 is readable, to avoid deadlock.
12468 Check for pipe I/O error.
12469 * src/scan-skel.l (readpipe): Remove decl.
12470 (scan_skel): New function, to be used in place of m4_invoke.
12471 Read from stream rather than file.
12473 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
12474 float, as this generates a warning on Solaris 8 + GCC 3.2 with
12475 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
12476 this generates a more-accurate value anyway.
12478 * lib/timevar.c (timervar_accumulate): Rename locals to
12479 avoid confusion with similarly-named more-global.
12480 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
12482 * src/output.c (prepare): Use xstrdup to convert char const *
12483 to char *, to avoid GCC warning.
12485 2002-10-19 Akim Demaille <akim@epita.fr>
12487 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
12488 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
12489 Use them to have `calc.y' ready for %pure-parser.
12490 * data/yacc.c (YYLEX): Pass a yylex return type to
12491 b4_c_function_call.
12493 2002-10-19 Akim Demaille <akim@epita.fr>
12495 Prototype support of %lex-param and %parse-param.
12497 * src/parse-gram.y: Add the definition of the %lex-param and
12498 %parse-param tokens, plus their rules.
12499 Drop the `_' version of %glr-parser.
12501 * src/scan-gram.l (INITIAL): Scan them.
12502 * src/muscle_tab.c: Comment changes.
12503 (muscle_insert, muscle_find): Rename `pair' as `probe'.
12504 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
12505 (muscle_entry_s): The `value' member is no longer const.
12506 Adjust all dependencies.
12507 * src/muscle_tab.c (muscle_init): Adjust: use
12508 MUSCLE_INSERT_STRING.
12509 Initialize the obstack earlier.
12510 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
12511 (muscle_pair_list_grow): New.
12512 * data/c.m4 (b4_c_function_call, b4_c_args): New.
12513 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
12514 * tests/calc.at: Use %locations, not --locations.
12515 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
12517 2002-10-19 Akim Demaille <akim@epita.fr>
12519 * src/getargs.c (usage): Take status as argument and exit
12521 Report the traditional `Try ... --help' message when status != 0.
12522 (usage, version): Don't take a FILE * as arg, it is pointless.
12523 (getargs): When there is an incorrect number of arguments, make it
12524 an error, and report it GNUlically thanks to `usage ()'.
12526 2002-10-18 Paul Eggert <eggert@twinsun.com>
12528 * data/glr.c (yyreportParseError): Don't assume that sprintf
12529 yields the length of the printed string, as this is not true
12530 on SunOS 4.1.4. Reported by Peter Klein.
12532 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
12533 * tests/conflicts.at (%nonassoc and eof): Likewise.
12534 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
12536 2002-10-17 Akim Demaille <akim@epita.fr>
12538 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
12539 * src/getargs.c (trace_types, trace_args): Adjust.
12540 * src/reader.c (grammar_current_rule_prec_set)
12541 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
12542 Standardize error messages.
12543 And s/@prec/%prec/!
12544 (reader): Use trace_flag to enable scanner/parser debugging,
12545 instead of an adhoc scheme.
12546 * src/scan-gram.l: Remove trailing debugging code.
12548 2002-10-16 Paul Eggert <eggert@twinsun.com>
12550 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
12553 * NEWS: Officially drop support for building Bison with K&R C,
12554 since it didn't work anyway and it's not worth worrying about.
12555 * Makefile.maint (wget_files): Remove ansi2knr.c.
12556 (ansi2knr.c-url_prefix): Remove.
12557 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
12558 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
12559 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
12561 2002-10-15 Paul Eggert <eggert@twinsun.com>
12563 Stop using the "enum_" trick for K&R-style function definitions;
12564 it confused me, and I was the author! Instead, assume that people
12565 who want to use K&R C compilers (when using these modules in GCC,
12566 perhaps?) will run ansi2knr.
12568 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
12569 All uses of "enum_" changed to "enum ".
12570 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
12571 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
12573 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

12580 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
12581 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
12582 Use function prototypes; this removes the need for declaring
12583 static functions simply to provide their prototypes.
12584 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

12641 2002-10-14 Akim Demaille <akim@epita.fr>
12643 * tests/Makefile.am (maintainer-check-posix): New.
12645 2002-10-14 Akim Demaille <akim@epita.fr>
12647 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
12650 2002-10-14 Akim Demaille <akim@epita.fr>
12652 * src/tables.c (table_ninf_remap): base -> tab.
12653 Reported by Matt Rosing.
12655 2002-10-14 Paul Eggert <eggert@twinsun.com>
12657 * tests/action.at, tests/calc.at, tests/conflicts.at,
12658 tests/cxx-type.at, tests/headers.at, tests/input.at,
12659 tests/regression.at, tests/synclines.at, tests/torture.at:
12660 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
12661 so that the tests still work even if POSIXLY_CORRECT is set.
12662 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
12664 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
12665 for portability to K&R hosts. Fix typo: signed char is guaranteed
12666 only to 127, not to 128.
12667 * data/glr.c (yysigned_char): New type.
12668 * data/yacc.c (yysigned_char): Likewise.
12669 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
12671 2002-10-13 Paul Eggert <eggert@twinsun.com>
12673 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
12674 true due to limited range of data type" warning from GCC.
12676 * data/c.m4 (b4_token_defines): Protect against double-inclusion
12677 by wrapping enum yytokentype's definition inside #ifndef
12678 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
12680 2002-10-13 Akim Demaille <akim@epita.fr>
12682 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
12683 Un yy- yyrhs to avoid the name clash with the global YYRHS.
12685 2002-10-13 Akim Demaille <akim@epita.fr>
12687 * Makefile.maint: Update from Autoconf 2.54.
12688 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
12690 2002-10-13 Akim Demaille <akim@epita.fr>
12692 * src/print.c (print_state): Separate the list of solved conflicts
12693 from the other items.
12694 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
12696 2002-10-13 Akim Demaille <akim@epita.fr>
12698 Let nondeterministic skeletons be usable with deterministic
12701 With the patch, GAWK compiled by GCC without -O2 passes its test
12702 suite using a GLR parser driven by LALR tables. It fails with -O2
12703 because `struct stat' gives two different answers on my machine:
12704 88 (definition of an auto var) and later 96 (memset on this var).
12705 Hence the stack is badly corrumpted. The headers inclusion is to
12706 blame: if I move the awk.h inclusion before GLR's system header
12707 inclusion, the two struct stat have the same size.
12709 * src/tables.c (pack_table): Always create conflict_table.
12710 (token_actions): Always create conflict_list.
12711 * data/glr.c (YYFLAG): Remove, unused.

12715 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
12717 (VALGRIND, GXX): New.
12718 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
12719 * tests/bison.in: Run $PREBISON a pre-command.
12720 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
12721 (maintainer-check-g++): New.
12722 * Makefile.am (maintainer-check): New.
12724 2002-10-13 Akim Demaille <akim@epita.fr>
12726 * data/glr.c: Formatting changes.
12727 Tweak some trace messages to match yacc.c's.
12729 2002-10-13 Akim Demaille <akim@epita.fr>
12731 GLR parsers sometimes raise parse errors instead of performing the
12733 Reported by Charles-Henry de Boysson.
12735 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
12736 check the length of the traces when %glr.
12737 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
12739 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
12741 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
12742 (yyltype): Remove the yy prefix from the member names.
12743 (yytable): Complete its comment.
12744 (yygetLRActions): Map error action number from YYTABLE from
12746 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
12747 (which was a bug: it should have been YYTABEL_NINF, and yet it was
12748 not satisfying as we could compare an YYACTION computed from
12749 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
12750 only value for error actions.
12751 (yyreportParseError): In verbose parse error messages, don't issue
12752 `error' in the list of expected tokens.
12753 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
12754 next action to perform to match glr.c's decoding.
12755 (yytable): Complete its comment.

12759 Fix problem reported by Henrik Grubbstroem in
12760 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
12761 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
12762 because the Bison parser reads the second action before reducing
12764 * src/scan-gram.l (rule_length): New static var.
12765 Use it to keep track of the rule length in the scanner, since
12766 we can't expect the parser to be in lock-step sync with the scanner.
12767 (handle_action_dollar, handle_action_at): Use this var.
12768 * tests/actions.at (Exotic Dollars): Test for the problem.
12770 2002-10-12 Paul Eggert <eggert@twinsun.com>
12772 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
12773 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
12774 Include <sys/time.h> when checking for clock_t and struct tms.
12775 Use same include order as source.
12776 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
12777 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
12779 * lib/timevar.c: Update copyright date and clarify comments.
12780 (get_time) [IN_GCC]: Keep the GCC version for reference.
12782 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
12783 GCC version as of today, then merge Bison's changes.
12784 Change "GCC" to "Bison" in copyright notice. timevar.def's
12785 author is Akim, so change that too.
12787 * src/reader.c (grammar_current_rule_check):
12788 Don't worry about the default action if $$ is untyped.
12789 Prevents bogus warnings reported by Jim Gifford in
12790 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
12792 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
12793 * data/glr.c, data/lalr1.cc, data/yacc.c:
12794 Output token definitions before the first part of user declarations.
12795 Fixes compatibility problem reported by Jim Gifford for kbd in
12796 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
12798 2002-10-11 Paul Eggert <eggert@twinsun.com>
12800 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
12801 (yyparse): here. This undoes some of the 2002-07-25 change.
12802 Compatibility problem reported by Ralf S. Engelschall with
12803 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
12805 2002-10-11 Akim Demaille <akim@epita.fr>
12807 * tests/regression.at Characters Escapes): New.
12808 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and

12816 2002-10-10 Paul Eggert <eggert@twinsun.com>
12818 Portability fixes for bitsets; this also avoids several GCC
12821 * lib/abitset.c: Include <stddef.h>, for offsetof.
12822 * lib/lbitset.c: Likewise.
12824 * lib/abitset.c (abitset_bytes): Return a size that is aligned
12825 properly for vectors of objects. Do not assume that adding a
12826 header size to a multiple of a word size yields a value that is
12827 properly aligned for the whole union.
12828 * lib/bitsetv.c (bitsetv_alloc): Likewise.
12830 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
12831 unique names for structures.
12832 * lib/ebitset.c (ebitset_bytes): Likewise.
12833 * lib/lbitset.c (lbitset_bytes): Likewise.
12835 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,

12840 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
12841 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
12842 to improve the type-checking that GCC can do.
12843 * lib/bitset.c (bitset_op4_cmp): Likewise.
12844 * lib/bitset_stats.c (bitset_stats_count,
12845 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

12860 * lib/ebitset.h: Likewise.
12861 * lib/lbitset.h: Likewise.
12863 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
12864 All instances of parameters of type enum bitset_opts are now of
12865 type enum_bitset_opts, to conform to the C Standard, and similarly
12866 for enum_bitset_type.
12867 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
12868 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
12870 Do not use "struct bitset_struct" to mean different things in
12871 different modules. Not only is this confusing, it violates
12872 the C Standard, which requires that structure types in different
12873 modules must be compatible if one is to be passed to the other.
12874 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
12875 All instances of "struct bitset_struct *" replaced with "bitset".
12876 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
12877 (union bitset_union, struct abitset_struct, struct ebitset_struct,
12878 struct lbitset_struct, struct bitset_stats_struct): New types.
12879 All uses of struct bitset_struct changed to union bitset_union,

12884 struct bitset_struct): Remove.
12885 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
12886 bitset_struct): Remove.
12887 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
12890 Do not call a function of type T using a call that assumes the
12891 function is of a different type U. Standard C requires that a
12892 function must be called with a type that is compatible with its
12894 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
12896 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
12898 * lib/ebitset.c (PFV): Remove.
12899 * lib/lbitset.c (PFV): Likewise.
12900 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,

12907 (lbitset_vtable): Use them.
12909 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
12912 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
12914 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
12915 Use offsetof, for simplicity.
12917 2002-10-06 Paul Eggert <eggert@twinsun.com>
12919 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
12920 the same width as int. This reapplies a hunk of the 2002-08-12 patch
12921 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
12922 which was inadvertently undone by the 2002-09-30 patch.
12923 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
12924 the same width as int.
12926 2002-10-04 Paul Eggert <eggert@twinsun.com>
12930 * configure.ac (AC_INIT), NEWS: Increment version number.
12932 * doc/bison.texinfo: Minor spelling, grammar, and white space
12934 (Symbols): Mention that any negative value returned from yylex
12935 signifies end-of-input. Warn about negative chars. Mention
12936 the portable Standard C character set.
12938 The GNU coding standard says CFLAGS and YFLAGS are reserved
12939 for the installer to set.
12940 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
12941 * src/Makefile.am (AM_CFLAGS): Likewise.
12942 (AM_YFLAGS): Renamed from YFLAGS.
12944 Fix some MAX and MIN problems.

12946 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
12947 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
12948 * src/reader.c (reader): Use it.
12950 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
12951 POSIX 1003.1-2001 has removed fgrep.
12953 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
12955 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
12956 interpreted as signed.

13029 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

13232 (bitset_test): Now returns int, not unsigned long.

13281 as it mishandles negative chars and it may not work as expected
13282 outside the C locale.
13284 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
13285 this is a GCC extension and is not portable to other compilers.

13295 * tests/regression.at: Do not use 'cc -c input.c -o input';

13298 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
13299 exit status as failure, not just exit status 1. Sun C exits
13300 with status 2 sometimes.

13467 different: save its reduction (accept) instead of having a state
13468 without any action (no shift or goto, no reduce).
13469 Note: the final state is now a ``regular'' state, i.e., the
13470 parsers now contain `reduce 0' as default reduction.
13471 Nevertheless, since they decide to `accept' when yystate =
13472 final_state, they still will not reduce rule 0.

13518 yycontrol without making too strong assumptions on the parser
13520 * src/output.c (prepare_tokens): Use the real 0th value of
13521 token_translations instead of `0'.
13522 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
13524 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
13525 for the time being: %locations ought to provide it to yyerror.
13527 2002-07-25 Akim Demaille <akim@epita.fr>
13529 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

13541 Use rule_number_as_item_number and item_number_as_rule_number.
13542 Adjust to `derive' now containing possibly 0.
13543 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
13544 Handle the `- 1' part in rule numbers from/to item numbers.
13545 * src/conflicts.c (log_resolution): Fix the message which reversed

14659 Make the use of `p' as local as possible.
14661 2002-06-10 Akim Demaille <akim@epita.fr>

14690 Remove `%thong' support as it is undocumented, unused, duplicates
14691 `%token's job, and creates useless e-mail traffic with people who

15068 values of $$, $n and so forth, output invocation to b4_lhs_value,
15069 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
15070 Note: this patch partially drops `semantic-parser' support: it
15071 always does `rule_length - n', where semantic parsers ought to

15144 YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
15145 if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
15146 constructors or destructors.
15148 (yyparse) [! defined YYSTACK_RELOCATE]: Do not relocate the stack.

15175 * tests/regression.at (Web2c Actions): Adjust.
15177 2002-04-22 Akim Demaille <akim@epita.fr>
15179 * src/reader.c (token_translations_init): 256 is now the default
15180 value for the error token, i.e., it will be assigned another
15181 number if the user assigned 256 to one of her tokens.
15182 (reader): Don't force 256 to error.
15183 * doc/bison.texinfo (Symbols): Adjust.

15185 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
15186 etc. instead of 10, 20, 30 (which was used to `jump' over error
15187 (256) and undefined (2)).
15189 2002-04-22 Akim Demaille <akim@epita.fr>

15226 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
15227 full stderr, and strip it according to the bison options, instead
15228 of composing the error message from different bits.
15229 This makes it easier to check for several error messages.
15230 Adjust all the invocations.
15231 Add an invocation exercising the error token.
15232 Add an invocation demonstrating a stupid error message.
15233 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

15239 * src/gram.h, src/gram.c (error_token_number): Remove, use
15241 * src/reader.c (reader): Don't specify the user token number (2)
15242 for $undefined, as it uselessly prevents using it.

15244 * src/symtab.h: here.
15245 (state_t.number): Is a token_number_t.
15246 * src/print.c, src/reader.c: Use undeftoken->number instead of
15248 (Even though this 2 is not the same as above: the number of the
15249 undeftoken remains being 2, it is its user token number which
15251 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
15252 `user_token_number_max'.
15253 Output `undef_token_number'.
15254 * data/bison.simple, data/bison.c++: Use them.

15274 * src/gram.h (item_number_t): New, the type of item numbers in
15275 RITEM. Note that it must be able to code symbol numbers as
15276 positive number, and the negation of rule numbers as negative

15279 * src/reduce.c (rule): Remove this `short *' pointer: use
15281 * src/system.h (MINSHORT, MAXSHORT): Remove.

15291 * tests/regression.at (Web2c Actions): Ajust.
15293 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
15294 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
15295 passes, but produces negative #line number, once fixed, GCC is

15450 Be sure to distinguish the initial from the final state.

15454 items properly set, there is no need for a special case when

15491 (reduce_output, dump_grammar): Adjust.
15492 * src/print.c (print_grammar): It is no longer needed to check for
15493 the usefulness of a rule, as useless rules are beyond `nrules + 1'.

15496 2002-04-07 Akim Demaille <akim@epita.fr>
15498 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
15499 lacking `+ 1' to nrules, Bison reported as useless a token if it
15500 was used solely to set the precedence of the last rule...
15502 2002-04-07 Akim Demaille <akim@epita.fr>
15504 * data/bison.c++, data/bison.simple: Don't output the current file
15505 name in #line, to avoid useless diffs between two identical
15506 outputs under different names.
15508 2002-04-07 Akim Demaille <akim@epita.fr>
15510 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

15525 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
15526 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
15527 RHS, instead of being an index in RITEMS.
15529 2002-04-04 Paul Eggert <eggert@twinsun.com>
15531 * doc/bison.texinfo: Update copyright date.
15532 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.
15533 (Symbols): Warn about running Bison in one character set,
15534 but compiling and/or running in an incompatible one.
15535 Warn about character code 256, too.
15537 2002-04-03 Paul Eggert <eggert@twinsun.com>

16055 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
16056 * configure.in: Check for the presence of memrchr, and of its
16059 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
16061 * lib/hash.h (__P): Added definition for this macro.
16062 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
16063 BUILT_SOURCES, to ensure they are generated first.
16064 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
16065 %error-verbose to allow bootstrapping with bison 1.30x.
16067 2002-01-06 Akim Demaille <akim@epita.fr>
16069 * src/reader.c (parse_braces): Don't fetch the next char, the
16070 convention is to fetch on entry.
16071 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
16072 'switch' without a following semicolon.
16073 * tests/regression.at (braces parsing): New.
16075 2002-01-06 Akim Demaille <akim@epita.fr>
16077 Bison is dead wrong in its RR conflict reports.
16079 * tests/torture.at (GNU Cim Grammar): New.
16080 * src/conflicts.c (count_rr_conflicts): Fix.
16082 2002-01-06 Akim Demaille <akim@epita.fr>
16084 Creating package.m4 from configure.ac causes too many problems.
16086 * tests/Makefile.am (package.m4): Create it by hand,
16087 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
16089 2002-01-06 Akim Demaille <akim@epita.fr>
16091 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
16094 2002-01-04 Paul Eggert <eggert@twinsun.com>
16096 * doc/bison.texinfo (Debugging):
16097 Remove YYSTDERR; it's no longer defined or used.
16098 Also, s/cstdio.h/cstdio/.
16100 2002-01-03 Akim Demaille <akim@epita.fr>
16102 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
16104 2002-01-03 Akim Demaille <akim@epita.fr>
16106 * src/parse-skel.y (process_skeleton): Don't bind the parser's
16107 tracing code to --trace, wait for a better --trace option, with
16110 2002-01-03 Akim Demaille <akim@epita.fr>
16112 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
16113 The ISO C++ standard is extremely clear about it: stderr is
16114 considered a macro, not a regular symbol (see table 94 `Header
16115 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
16116 Therefore std:: does not apply to it. It still does with fprintf.
16117 Also, s/cstdio.h/cstdio/.
16119 2002-01-03 Akim Demaille <akim@epita.fr>
16121 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
16122 for non system headers.
16124 2002-01-02 Akim Demaille <akim@epita.fr>
16126 Equip the skeleton chain with location tracking, runtime trace,
16127 pure parser and scanner.
16129 * src/parse-skel.y: Request a pure parser, locations, and prefix
16131 (%union): Having several members with the same type does not help
16132 type mismatches, simplify.
16133 (YYPRINT, yyprint): New.
16134 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
16135 (skel_error): this.
16137 * src/scan-skel.l: Adjust to these changes.
16138 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
16139 (LOCATION_PRINT, skel_control_t): New.
16141 2001-12-30 Akim Demaille <akim@epita.fr>
16143 * src/parse-skel.y: Get rid of the shift/reduce conflict:
16144 replace `gb' with BLANKS.
16145 * src/scan-skel.l: Adjust.
16147 2001-12-30 Akim Demaille <akim@epita.fr>
16149 * src/system.h: We don't need nor want bcopy.
16150 Throw away MS-DOS crap: we don't need getpid.
16151 * configure.in: We don't need strndup. It was even causing
16152 problems: because Flex includes the headers *before* us,
16153 _GNU_SOURCE is not defined by config.h, and therefore strndup was
16155 * lib/xstrndup.c: New.
16156 * src/scan-skel.l: Use it.
16157 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
16158 * src/parse-skel.y: Use %directives instead of #defines.
16160 2001-12-30 Akim Demaille <akim@epita.fr>
16162 * src/skeleton.h: New.
16163 * src/output.c (output_parser, output_master_parser): Remove, dead
16165 * src/output.h (get_lines_number, actions_output, guards_output)
16166 (token_definitions_output): Prototype them.
16167 * src/parse-skel.y: Add the license notice.
16168 Include output.h and skeleton.h.
16169 (process_skeleton): Returns void, and takes a single parameter.
16170 * src/scan-skel.l: Add the license notice.
16171 Include skeleton.h.
16172 Don't use %option yylineno: it seems that then Flex imagines
16173 REJECT has been used, and therefore it won't reallocate its
16174 buffers (which makes no other sense to me than a bug). It results
16175 in warnings for `unused: yy_flex_realloc'.
16177 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
16179 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16180 (MUSCLE_INSERT_PREFIX): ...to there.
16181 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16182 (MUSCLE_INSERT_PREFIX): Move from here...
16184 * src/bison.hairy: Add a section directive. Put braces around muscle
16185 names. This parser skeleton is still broken, but Bison should not
16186 choke on a bad muscle 'syntax'.
16187 * src/bison.simple: Add a section directive. Put braces around muscle
16190 * src/files.h (strsuffix, stringappend): Add declarations.
16191 (tab_extension): Add declaration.
16192 (short_base_name): Add declaration.
16194 * src/files.c (strsuffix, stringappend): No longer static. These
16195 functions are used in the skeleton parser.
16196 (tab_extension): New.
16197 (compute_base_names): Use the computations done in this function
16198 to guess if the generated parsers should have '.tab' in their
16200 (short_base_name): No longer static.
16202 * src/output.c (output_skeleton): New.
16203 (output): Disable call to output_master_parser, and give a try to
16204 a new skeleton handling system.
16205 (guards_output, actions_output): No longer static.
16206 (token_definitions_output, get_lines_number): No longer static.
16208 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
16210 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
16213 * src/parse-skel.y: New file.
16214 * src/scan-skel.l: New file.
16216 2001-12-29 Akim Demaille <akim@epita.fr>
16218 %name-prefix is broken.
16220 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
16221 Adjust all dependencies.
16222 * tests/headers.at (export YYLTYPE): Strengthen this test: use
16225 Renaming yylval but not yylloc is not consistent. Now we do.
16227 * src/bison.simple: Prefix yylloc if used.
16228 * doc/bison.texinfo (Decl Summary): Document that.
16230 2001-12-29 Akim Demaille <akim@epita.fr>
16232 * doc/bison.texinfo: Promote `%long-directive' over
16234 Remove all references to fixed-output-files, yacc is enough.
16236 2001-12-29 Akim Demaille <akim@epita.fr>
16238 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
16239 user prologue. These are defaults.
16240 * tests/actions.at (Mid-rule actions): Make sure the user can
16241 define YYDEBUG and YYERROR_VERBOSE.
16243 2001-12-29 Akim Demaille <akim@epita.fr>
16245 * src/output.c (header_output): Don't forget to export YYLTYPE and
16247 * tests/headers.at (export YYLTYPE): New, make sure it does.
16248 * tests/regression.at (%union and --defines, Invalid CPP headers):
16250 * tests/headers.at: here.
16252 2001-12-29 Akim Demaille <akim@epita.fr>
16254 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
16256 2001-12-29 Akim Demaille <akim@epita.fr>
16258 * tests/actions.at (Mid-rule actions): Output on a single line
16259 instead of several.
16261 2001-12-29 Akim Demaille <akim@epita.fr>
16263 * doc/bison.texinfo: Formatting changes.
16265 2001-12-29 Akim Demaille <akim@epita.fr>
16267 Don't store the token defs in a muscle, just be ready to output it
16268 on command. Now possible via `symbols'. Fixes a memory leak.
16270 * src/output.c (token_definitions_output): New.
16271 (output_parser, header_output): Use it.
16272 * src/reader.c (symbols_save): Remove.
16274 2001-12-29 Akim Demaille <akim@epita.fr>
16276 * src/bison.simple: Do not provide a default for YYSTYPE and
16277 YYLTYPE before the user's prologue. Otherwise it's hardly... a
16280 2001-12-29 Akim Demaille <akim@epita.fr>
16282 Mid-rule actions are simply... ignored!
16284 * src/reader.c (readgram): Be sure to attach mid-rule actions to
16285 the empty-rule associated to the dummy symbol, not to the host
16287 * tests/actions.at (Mid-rule actions): New.
16289 2001-12-29 Akim Demaille <akim@epita.fr>
16293 * src/reader.c (reader): Free grammar.
16295 2001-12-29 Akim Demaille <akim@epita.fr>
16299 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
16300 since it allocates it for each state, although only one is needed.
16301 (allocate_storage): Do it here.
16303 2001-12-29 Akim Demaille <akim@epita.fr>
16305 * src/options.h, src/options.c (create_long_option_table): Rename
16307 (long_option_table_new): this, with a clearer prototype.
16308 (percent_table): Remove, unused,
16309 * src/getargs.c (getargs): Adjust.
16311 2001-12-29 Akim Demaille <akim@epita.fr>
16313 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
16314 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
16317 2001-12-29 Akim Demaille <akim@epita.fr>
16319 * src/lalr.c (build_relations): Rename `states' as `states1'.
16320 Sorry, I don't understand exactly what it is, no better name...
16322 2001-12-29 Akim Demaille <akim@epita.fr>
16324 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
16325 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
16326 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
16329 2001-12-29 Akim Demaille <akim@epita.fr>
16331 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
16334 2001-12-29 Akim Demaille <akim@epita.fr>
16336 * src/reader.c, src/reader.h (user_toknums): Remove.
16337 Adjust all users to use symbols[i]->user_token_number.
16339 2001-12-29 Akim Demaille <akim@epita.fr>
16341 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
16342 Adjust all users to use symbols[i]->prec or ->assoc.
16344 2001-12-29 Akim Demaille <akim@epita.fr>
16346 * src/reader.c, src/reader.h (tags): Remove.
16347 Adjust all users to use symbols[i]->tag.
16349 2001-12-29 Akim Demaille <akim@epita.fr>
16351 * src/gram.h, src/gram.c (symbols): New, similar to state_table
16353 * src/reader.c (packsymbols): Fill this table.
16355 * src/conflicts.c (resolve_sr_conflict): Adjust.
16356 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
16358 Use symbols[i]->tag instead of tags[i].
16360 2001-12-29 Akim Demaille <akim@epita.fr>
16362 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
16363 In addition, put a comment in there, to replace...
16364 * tests/regression.at (%union and C comments): Remove.
16366 2001-12-29 Akim Demaille <akim@epita.fr>
16368 * tests/regression.at (Web2c Actions): Blindly move the actual
16369 output as expected output. The contents *seem* right to me, but I
16370 can't pretend reading perfectly parser tables... Nonetheless, all
16371 the other tests pass correctly, the table look OK, even though the
16372 presence of `$axiom' is to be noted: AFAICS it is useless (but
16375 2001-12-29 Akim Demaille <akim@epita.fr>
16377 * src/reader.c (readgram): Don't add the rule 0 if there were no
16378 rules read. In other words, add it _after_ having performed
16379 grammar sanity checks.
16380 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
16382 2001-12-29 Akim Demaille <akim@epita.fr>
16384 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
16385 visible, and some states have now a different number.
16387 2001-12-29 Akim Demaille <akim@epita.fr>
16389 * src/reader.c (readgram): Bind the initial rule's lineno to that
16391 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
16392 (Solved SR Conflicts): Adjust rule 0's line number.
16394 2001-12-29 Akim Demaille <akim@epita.fr>
16396 Fix the `GAWK Grammar' failure.
16398 * src/LR0.c (final_state): Initialize to -1 so that we do compute
16399 the reductions of the first state which was mistakenly confused
16400 with the final state because precisely final_state was initialized
16402 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
16403 now noticed by Bison.
16404 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
16405 have a reduction on $default.
16407 2001-12-29 Akim Demaille <akim@epita.fr>
16409 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
16411 * src/closure.c (print_closure): Likewise.
16412 * src/derives.c (print_derives): Likewise.
16413 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
16416 2001-12-29 Akim Demaille <akim@epita.fr>
16418 * src/lalr.c (lookaheads_print): New.
16419 (lalr): Call it when --trace-flag.
16420 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
16423 2001-12-29 Akim Demaille <akim@epita.fr>
16425 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
16426 when walking through ritem, even via rule->rhs.
16427 * src/reduce.c (dump_grammar, useful_production, reduce_output)
16428 (useful_production, useless_nonterminals): Likewise.
16429 (reduce_grammar_tables): Likewise, plus update nritems.
16430 * src/nullable.c (set_nullable): Likewise.
16431 * src/lalr.c (build_relations): Likewise.
16432 * tests/sets.at (Nullable): Adjust.
16433 Fortunately, now, the $axiom is no longer nullable.
16435 2001-12-29 Akim Demaille <akim@epita.fr>
16437 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
16439 * src/gram.c (ritem_longest_rhs): Likewise.
16440 * src/reduce.c (nonterminals_reduce): Likewise.
16441 * src/print_graph.c (print_graph): Likewise.
16442 * src/output.c (output_rule_data): Likewise.
16443 * src/nullable.c (set_nullable): Likewise.
16445 2001-12-29 Akim Demaille <akim@epita.fr>
16447 * src/output.c: Comment changes.
16449 2001-12-27 Paul Eggert <eggert@twinsun.com>
16451 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
16452 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
16453 Sparc, as they were causing more porting problems than the
16454 (minor) performance improvement was worth.
16456 Also, catch up with 1.31's YYSTD.
16458 2001-12-27 Akim Demaille <akim@epita.fr>
16460 * src/output.c (output_gram): Rely on nritems, not the
16461 0-sentinel. See below.
16462 Use -1 as separator, not 0.
16463 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
16464 Rely on -1 as separator in yyrhs, instead of 0.
16465 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
16466 twice `Now at end of input', therefore there are two lines less to
16469 2001-12-27 Akim Demaille <akim@epita.fr>
16471 * tests/regression.at (Unresolved SR Conflicts):
16472 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
16475 2001-12-27 Akim Demaille <akim@epita.fr>
16477 * src/LR0.c (new_state): Recognize the final state by the fact it
16478 is reached by eoftoken.
16479 (insert_start_shifting_state, insert_eof_shifting_state)
16480 (insert_accepting_state, augment_automaton): Remove, since now
16481 these states are automatically computed from the initial state.
16482 (generate_states): Adjust.
16483 * src/print.c: When reporting a rule number to the user, substract
16484 1, so that the axiom rule is rule 0, and the first user rule is 1.
16485 * src/reduce.c: Likewise.
16486 * src/print_graph.c (print_core): For the time being, just as for
16487 the report, depend upon --trace-flags to dump the full set of
16489 * src/reader.c (readgram): Once the grammar read, insert the rule
16490 0: `$axiom: START-SYMBOL $'.
16491 * tests/set.at: Adjust: rule 0 is now displayed, and since the
16492 number of the states has changed (the final state is no longer
16493 necessarily the last), catch up.
16495 2001-12-27 Akim Demaille <akim@epita.fr>
16497 Try to make the use of the eoftoken valid. Given that its value
16498 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
16499 is used instead of > 0 where appropriate, (ii), depend upon nritems
16500 instead of the 0-sentinel.
16502 * src/gram.h, src/gram.c (nritems): New.
16503 Expected to be duplication of nitems, but for the time being...
16504 * src/reader.c (packgram): Assert nritems and nitems are equal.
16505 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
16506 * src/closure.c (print_closure, print_fderives): Likewise.
16507 * src/gram.c (ritem_print): Likewise.
16508 * src/print.c (print_core, print_grammar): Likewise.
16509 * src/print_graph.c: Likewise.
16511 2001-12-27 Akim Demaille <akim@epita.fr>
16513 * src/main.c (main): If there are complains after grammar
16514 reductions, then output the report anyway if requested, then die.
16515 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
16516 * src/reader.c (eoftoken): New.
16517 (parse_token_decl): If the token being defined has value `0', it
16519 (packsymbols): No longer hack `tags' to insert `$' by hand.
16520 Be sure to preserve the value of the eoftoken.
16521 (reader): Make sure eoftoken is defined.
16522 Initialize nsyms to 0: now eoftoken is created just like the others.
16523 * src/print.c (print_grammar): Don't special case the eof token.
16524 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
16525 lie anyway, albeit pleasant.
16526 * tests/calc.at: Exercise error messages with eoftoken.
16527 Change the grammar so that empty input is invalid.
16528 Adjust expectations.
16529 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
16531 2001-12-27 Akim Demaille <akim@epita.fr>
16533 * configure.in: Check the protos of strchr ans strspn.
16534 Replace strchr if needed.
16535 * src/system.h: Provide the protos of strchr, strspn and memchr if
16537 * lib/strchr.c: New.
16538 * src/reader.c (symbols_save): Use strchr.
16540 2001-12-27 Akim Demaille <akim@epita.fr>
16542 * src/print.c, src/print_graph.c (escape): New.
16543 Use it to quote the TAGS outputs.
16544 * src/print_graph.c (print_state): Now errors are in red, and
16545 reductions in green.
16546 Prefer high to wide: output the state number on a line of its own.
16548 2001-12-27 Akim Demaille <akim@epita.fr>
16550 * src/state.h, src/state.c (reductions_new): New.
16551 * src/LR0.c (set_state_table): Let all the states have a
16552 `reductions', even if reduced to 0.
16553 (save_reductions): Adjust.

16564 * src/output.c (output_actions, action_row): Adjust.

16571 2001-12-27 Akim Demaille <akim@epita.fr>
16573 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
16574 * src/print.c: here.
16575 (lookaheadset, shiftset): New, used as additional storage by
16577 (print_results): Adjust.
16578 (print_shifts, print_gotos, print_errs): New, extracted from...
16579 (print_actions): here.
16580 * src/print_graph.c (print_actions): Remove dead code.
16582 2001-12-27 Akim Demaille <akim@epita.fr>
16584 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
16587 2001-12-27 Akim Demaille <akim@epita.fr>
16589 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
16590 (build_relations): Adjust.
16592 2001-12-27 Akim Demaille <akim@epita.fr>
16594 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
16597 2001-12-27 Akim Demaille <akim@epita.fr>
16599 * src/reader.c (packgram): Catch nitems overflows.
16601 2001-12-27 Akim Demaille <akim@epita.fr>
16603 * src/files.c, src/files.h (guard_obstack): Remove.
16604 * src/output.c (output): Adjust.
16605 * src/reader.c (parse_braces): New, factoring...
16606 (copy_action, copy_guard): these two which are renamed as...
16607 (parse_action, parse_guard): these.
16608 As a voluntary consequence, using braces around guards is now
16611 2001-12-27 Akim Demaille <akim@epita.fr>
16613 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
16614 * src/reader.c (symbol_list): `guard' and `guard_line' are new
16616 (symbol_list_new): Adjust.
16617 (copy_action): action_line is the first line, not the last.
16618 (copy_guard): Just as for actions, store the `action' only, not
16619 the switch/case/break flesh.
16620 Don't parse the user action that might follow the guard, let...
16621 (readgram): do it, i.e., now, there can be an action after a
16623 In other words the guard is just explicitly optional.
16624 (packgram): Adjust.
16625 * src/output.c (guards_output): New.
16626 (output_parser): Call it when needed.
16627 (output): Also free the guard and attrs obstacks.
16628 * src/files.c, src/files.h (obstack_save): Remove.
16629 (output_files): Remove.
16630 As a result, if one needs the former `.act' file, using an
16631 appropriate skeleton which requires actions and guards is now
16633 * src/main.c (main): Adjust.
16634 * tests/semantic.at: New.
16635 * tests/regression.at: Use `input.y' as input file name.
16636 Avoid 8+3 problems by requiring input.c when the test needs the
16639 2001-12-27 Akim Demaille <akim@epita.fr>
16641 * src/reader.c (symbol_list_new): Be sure to initialize all the
16644 2001-12-27 Akim Demaille <akim@epita.fr>
16646 All the hacks using a final pseudo state are now useless.
16648 * src/LR0.c (set_state_table): state_table holds exactly nstates.
16649 * src/lalr.c (nLA): New.
16650 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
16651 instead of lookaheadsp from the pseudo state (nstate + 1).
16653 2001-12-27 Akim Demaille <akim@epita.fr>
16655 * src/output.c (action_row, token_actions): Use a state_t instead
16656 of a integer, and nlookaheads instead of the following state's

16661 * src/conflicts.c (log_resolution, flush_shift)
16662 (resolve_sr_conflict, set_conflicts, solve_conflicts)
16663 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
16664 (conflicts_print, print_reductions): Use a state_t instead of an
16665 integer when referring to a state.
16666 As much as possible, depend upon nlookaheads, instead of the
16667 `lookaheadsp' member of the following state (since lookaheads of
16668 successive states are successive, the difference between state n + 1
16669 and n served as the number of lookaheads for state n).
16670 * src/lalr.c (add_lookback_edge): Likewise.
16671 * src/print.c (print_core, print_actions, print_state)
16672 (print_results): Likewise.
16673 * src/print_graph.c (print_core, print_actions, print_state)
16674 (print_graph): Likewise.

16677 2001-12-27 Akim Demaille <akim@epita.fr>
16679 * src/bison.hairy: Formatting/comment changes.

16682 Add plenty of `static'.
16684 2001-12-27 Akim Demaille <akim@epita.fr>
16686 * src/output.c (prepare): Drop the muscle `ntbase' which
16687 duplicates ntokens.
16688 * src/bison.simple: Formatting/comment changes.
16689 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
16690 is an undocumented synonym.
16692 2001-12-22 Akim Demaille <akim@epita.fr>
16694 * src/output.c (output_table_data): Change the prototype to use
16695 `int' for array ranges: some invocations do pass an int, not a
16697 Reported by Wayne Green.
16699 2001-12-22 Akim Demaille <akim@epita.fr>
16701 Some actions of web2c.y are improperly triggered.
16702 Reported by Mike Castle.
16704 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
16705 * tests/regression.at (Web2c): Rename as...
16706 (Web2c Report): this.
16707 (Web2c Actions): New.
16709 2001-12-22 Akim Demaille <akim@epita.fr>

16715 * tests/regression.at (Web2c): New.
16717 2001-12-18 Akim Demaille <akim@epita.fr>
16719 Some host fail on `assert (!"foo")', which expands to
16720 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
16721 Reported by Nelson Beebee.
16723 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
16724 `#define it_succeeded 0' and `assert (it_succeeded)'.
16726 2001-12-17 Marc Autret <autret_m@epita.fr>
16728 * src/bison.simple: Don't hard code the skeleton line and filename.
16729 * src/output.c (output_parser): Rename 'line' as 'output_line'.
16730 New line counter 'skeleton_line' (skeleton-line muscle).
16732 2001-12-17 Paul Eggert <eggert@twinsun.com>
16734 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
16735 YYDEBUG must be defined to a nonzero value.
16737 * src/bison.simple (yytname): Do not assume that the user defines
16738 YYDEBUG to a properly parenthesized expression.
16740 2001-12-17 Akim Demaille <akim@epita.fr>
16742 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
16743 nlookaheads is a new member.
16745 * src/lalr.h (nlookaheads): Remove this orphan declaration.
16746 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
16749 2001-12-17 Akim Demaille <akim@epita.fr>
16751 * src/files.h, src/files.c (open_files, close_files): Remove.
16752 * src/main.c (main): Don't open/close files, nor invoke lex_free,
16754 * src/reader.c (reader): Do it.
16756 2001-12-17 Akim Demaille <akim@epita.fr>
16758 * src/conflicts.c (print_reductions): Formatting changes.
16760 2001-12-17 Akim Demaille <akim@epita.fr>
16762 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
16763 (flush_reduce): New.
16764 (resolve_sr_conflict): Adjust.
16766 2001-12-17 Akim Demaille <akim@epita.fr>
16768 * src/output.c (output_obstack): Be static and rename as...
16769 (format_obstack): this, to avoid any confusion with files.c's
16771 * src/reader.h (muscle_obstack): Move to...
16772 * src/output.h: here, since it's defined in output.c.
16774 2001-12-17 Akim Demaille <akim@epita.fr>
16776 * src/output.c (action_row, save_column, default_goto)
16777 (sort_actions, matching_state, pack_vector): Better variable
16780 2001-12-17 Akim Demaille <akim@epita.fr>
16782 * src/output.c: Various formatting changes.
16784 2001-12-17 Akim Demaille <akim@epita.fr>
16786 * src/files.c (output_files): Free the output_obstack.
16787 * src/main.c (main): Call print and print_graph conditionally.
16788 * src/print.c (print): Work unconditionally.
16789 * src/print_graph.c (print_graph): Work unconditionally.
16790 * src/conflicts.c (log_resolution): Output only if verbose_flag.
16792 2001-12-16 Marc Autret <autret_m@epita.fr>
16794 * src/output.c (actions_output): Fix. When we use %no-lines,
16795 there is one less line per action.
16797 2001-12-16 Marc Autret <autret_m@epita.fr>
16799 * src/bison.simple: Remove a useless #line directive.
16800 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
16801 * src/output.c (get_lines_number): New.
16802 (output_parser): Adjust, now takes care about the lines of a
16804 Fix line numbering.
16805 (actions_output): Computes the number of lines taken by actions.
16806 (output_master_parser): Insert new skeleton which is the name of
16807 the output parser file name.
16809 2001-12-15 Marc Autret <autret_m@epita.fr>
16811 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
16813 2001-12-15 Marc Autret <autret_m@epita.fr>
16815 * src/output.c (output_gram): Keep track of the hairy one.
16817 2001-12-15 Akim Demaille <akim@epita.fr>
16819 Make `make distcheck' work.
16821 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
16822 system.h which uses libgettext.h.
16824 2001-12-15 Akim Demaille <akim@epita.fr>
16826 * src/nullable.c (set_nullable): Useless rules must be skipped,
16827 otherwise, since we range over their symbols, we might look at a
16828 nonterminal which no longer ``exists'', i.e., it is not counted in
16829 `nvars', hence we overflow our arrays.
16831 2001-12-15 Akim Demaille <akim@epita.fr>
16833 The header can also be produced directly, without any obstack!
16836 * src/files.c, src/files.h (defines_obstack): Remove.
16837 (compute_header_macro): Global.
16838 (defines_obstack_save): Remove.
16839 * src/reader.c (parse_union_decl): No longer output to
16840 defines_obstack: its content can be found in the `stype' muscle
16842 (output_token_translations): Merge into...
16843 (symbols_output): this.
16845 (symbols_save): this.
16847 * src/output.c (header_output): New.
16850 2001-12-15 Akim Demaille <akim@epita.fr>
16852 * src/reader.c (parse_union_decl): Instead of handling two obstack
16853 simultaneously, use one to define the `stype' muscle, and use the
16854 value of the latter to fill defines_obstack.
16855 (copy_comment): Remove.
16856 (copy_comment2): Work for a single obstack.
16858 (copy_comment): this.
16860 2001-12-15 Akim Demaille <akim@epita.fr>
16862 * src/lex.c, src/lex.h (xgetc): No longer static.
16863 * src/reader.c (parse_union_decl): Revamp.
16865 2001-12-15 Akim Demaille <akim@epita.fr>
16867 Still making progress in separating Bison into (i) input, (ii)
16868 process, (iii) output: now we can directly output the parser file
16869 without using table_obstack at all.
16871 * src/files.c, src/files.h (table_obstack): Bye bye.
16872 (parser_file_name): New.
16873 * src/files.c (compute_output_file_names): Compute it.
16874 * src/output.c (actions_output, output_parser)
16875 (output_master_parser): To a file instead of an obstack.
16877 2001-12-15 Akim Demaille <akim@epita.fr>
16879 Attach actions to rules, instead of pre-outputting them to
16882 * src/gram.h (rule_t): action and action_line are new members.
16883 * src/reader.c (symbol_list): Likewise.
16884 (copy_action): Save the actions within the rule.
16885 (packgram): Save them in rule_table.
16886 * src/output.c (actions_output): New.
16887 (output_parser): Use it on `%%actions'.
16888 (output_rule_data): Don't free rule_table.
16890 (prepare): Don't save the `action' muscle.
16891 * src/bison.simple: s/%%action/%%actions/.
16893 2001-12-15 Akim Demaille <akim@epita.fr>
16895 * src/reader.c (copy_action): When --yacc, don't append a `;'
16896 to the user action: let it fail if lacking.
16897 Suggested by Arnold Robbins and Tom Tromey.
16899 2001-12-14 Akim Demaille <akim@epita.fr>
16901 * src/lex.c (literalchar): Simply return the char you decoded, non
16902 longer mess around with obstacks and int pointers.
16903 Adjust all callers.
16905 2001-12-14 Akim Demaille <akim@epita.fr>
16907 * src/lex.c (literalchar): Don't escape the special characters,
16908 just decode them, and keep them as char (before, eol was output as
16909 the 2 char string `\n' etc.).
16910 * src/output.c (output_rule_data): Use quotearg to output the
16913 2001-12-13 Paul Eggert <eggert@twinsun.com>
16915 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
16916 Do not infringe on the global user namespace when using C++.
16917 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
16918 All uses of `fprintf' and `stderr' changed.
16920 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
16922 2001-12-13 Akim Demaille <akim@epita.fr>
16924 The computation of nullable is broken: it doesn't handle empty
16927 * tests/torture.at (GNU AWK Grammar): New.
16928 * tests/sets.at (Nullable): New.
16929 * src/nullable.c (set_nullable): Instead of blindly looping over
16930 `ritems', loop over the rules, and then over their rhs's.
16932 Work around Autotest bugs.
16934 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
16935 frame, because Autotest understand lines starting with a `+' as
16936 traces from the shell. Then, they are not processed properly.
16937 Admittedly an Autotest bug, but we don't have time to wait for
16938 Autotest to catch up.
16939 * tests/regression.at (Broken Closure): Adjust to the new table
16942 * tests/sets.at: here.
16944 2001-12-13 Akim Demaille <akim@epita.fr>
16946 * src/closure.c (closure): Use nrules instead of playing tricks
16947 with BITS_PER_WORD.
16949 2001-12-13 Akim Demaille <akim@epita.fr>
16951 * src/print.c (print_actions): Output the handling of `$' as the
16952 traces do: shifting the token EOF. Before EOF was treated as a
16954 * tests/regression.at: Adjust some tests.
16955 * src/print_graph.c (print_core): Complete the set of items via
16956 closure. The next-to-final and final states are still unsatisfying,
16957 but that's to be addressed elsewhere.
16958 No longer output the rule numbers, but do output the state number.
16959 A single loop for the shifts + gotos is enough, but picked a
16960 distinct color for each.
16961 (print_graph): Initialize and finalize closure.
16963 2001-12-13 Akim Demaille <akim@epita.fr>
16965 * src/reader.c (readgram): Remove dead code, an strip useless
16967 (get_type): Remove, unused.
16969 2001-12-12 Akim Demaille <akim@epita.fr>
16971 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
16972 on that of lib/error.c.
16974 2001-12-12 Akim Demaille <akim@epita.fr>
16976 Some hosts don't like `/' in includes.
16978 * src/system.h: Include libgettext.h without qualifying the path.
16979 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
16982 2001-12-11 Marc Autret <autret_m@epita.fr>
16984 * src/output.c (output_parser): Remove useless muscle.
16986 2001-12-11 Marc Autret <autret_m@epita.fr>
16988 * src/bison.simple: Remove #line just before %%epilogue. It
16989 is now handled in ...
16990 * src/reader.c (read_additionnal_code): Add the output of a
16991 #line for the epilogue.
16993 2001-12-10 Marc Autret <autret_m@epita.fr>
16995 * src/reader.c (copy_definition): Re-use CPP-outed code which
16996 replace precedent remove.
16997 * src/bison.simple: Remove #line before %%prologue because
16998 %%input-line is wrong at this time.
17000 2001-12-10 Marc Autret <autret_m@epita.fr>
17002 * src/reader.c (symbols_output): Clean up.
17003 * src/output.c (output_gram, output): Clean up.
17005 2001-12-10 Akim Demaille <akim@epita.fr>
17007 * src/lalr.c (initialize_lookaheads): New. Extracted from...
17008 * src/LR0.c (set_state_table): here.
17009 * src/lalr.c (lalr): Call it.
17011 2001-12-10 Akim Demaille <akim@epita.fr>
17013 * src/state.h (shifts): Remove the `number' member: shifts are
17014 attached to state, hence no longer need to be labelled with a
17017 2001-12-10 Akim Demaille <akim@epita.fr>
17019 Now that states have a complete set of members, the linked list of
17020 shifts is useless: just fill directly the state's shifts member.
17022 * src/state.h (shifts): Remove the `next' member.
17023 * src/LR0.c (first_state, last_state): Remove.
17024 Adjust the callers.
17025 (augment_automaton): Don't look for the shifts that must be added
17026 a shift on EOF: it is those of the state we looked for! But now,
17027 since shifts are attached, it is no longer needed to looking
17028 merely by its id: its number.
17030 2001-12-10 Akim Demaille <akim@epita.fr>
17032 * src/LR0.c (augment_automaton): Better variable locality.
17033 Remove an impossible branch: if there is a state corresponding to
17034 the start symbol being shifted, then there is shift for the start
17035 symbol from the initial state.
17037 2001-12-10 Akim Demaille <akim@epita.fr>
17039 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
17040 only when appropriate: when insert_start_shifting_state' is not
17042 * tests/regression.at (Rule Line Numbers): Adjust.
17044 2001-12-10 Akim Demaille <akim@epita.fr>
17046 * src/LR0.c (augment_automaton): Now that all states have shifts,
17047 merge the two cases addition shifts to the initial state.
17049 2001-12-10 Akim Demaille <akim@epita.fr>
17051 * src/lalr.c (set_state_table): Move to...
17053 * src/lalr.c (lalr): Don't call it...
17054 * src/LR0.c (generate_states): do it.
17055 * src/LR0.h (first_state): Remove, only the table is used.
17057 2001-12-10 Akim Demaille <akim@epita.fr>
17059 * src/LR0.h (first_shift, first_reduction): Remove.
17060 * src/lalr.c: Don't use first_shift: find shifts through the
17063 2001-12-10 Akim Demaille <akim@epita.fr>
17065 * src/LR0.c: Attach shifts to states as soon as they are
17067 * src/lalr.c (set_state_table): Instead of assigning shifts to
17068 state, just assert that the mapping was properly done.
17070 2001-12-10 Akim Demaille <akim@epita.fr>
17072 * src/LR0.c (insert_start_shift): Rename as...
17073 (insert_start_shifting_state): this.
17074 (insert_eof_shifting_state, insert_accepting_state): New.
17075 (augment_automaton): Adjust.
17076 Better locality of the variables.
17077 When looking if the start_symbol is shifted from the initial
17078 state, using `while (... symbol != start_symbol ...)' sounds
17079 better than `while (... symbol < start_symbol ...)': If fail
17080 to see how the order between symbols could be relevant!
17082 2001-12-10 Akim Demaille <akim@epita.fr>
17084 * src/getargs.h: Don't declare `spec_name_prefix' and
17085 `spec_file_prefix', declared by src/files.h.
17086 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
17087 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
17088 * src/output.c (prepare): Adjust.
17089 * src/reader.c (symbols_output): Likewise.
17090 * src/vmsgetargs.c: Vaguely adjust, but who cares?
17092 2001-12-10 Akim Demaille <akim@epita.fr>
17094 * src/muscle_tab.c (muscle_init): NULL is a better default than
17097 2001-12-10 Akim Demaille <akim@epita.fr>
17099 * src/reader.c (reader): Calling symbols_output once is enough.
17101 2001-12-10 Akim Demaille <akim@epita.fr>
17103 Now that states have a complete set of members, the linked list of
17104 reductions is useless: just fill directly the state's reductions
17107 * src/state.h (struct reductions): Remove member `number' and
17109 * src/LR0.c (first_reduction, last_reduction): Remove.
17110 (save_reductions): Don't link the new reductions, store them in
17112 * src/lalr.c (set_state_table): No need to attach reductions to
17113 states, it's already done.
17114 * src/output.c (output_actions): No longer free the shifts, then
17115 the reductions, then the states: free all the states and their
17118 2001-12-10 Akim Demaille <akim@epita.fr>
17120 * src/options.c (OPTN, DRTV, BOTH): New.
17121 (option_table): Use them.
17123 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
17124 the job of system.h.
17125 * src/options.c: Don't include stdio.h and xalloc.h for the same
17128 2001-12-10 Akim Demaille <akim@epita.fr>
17130 * src/output.c (output, prepare): Make sure the values of the
17131 muscles `action' and `prologue' are 0-terminated.
17133 2001-12-10 Akim Demaille <akim@epita.fr>
17135 Clean up GCC warnings.
17137 * src/reader.c (copy_action): `buf' is not used.
17138 (parse_skel_decl): Be static.
17139 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
17140 * src/options.h (create_long_option_table): Have a real prototype.
17141 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
17142 (hash_delete_at): Return const void *.
17143 Adjust casts to preserve the const.
17145 2001-12-10 Akim Demaille <akim@epita.fr>
17147 * configure.in: Require 2.52g.
17148 M4 is not needed, but AUTOM4TE is.
17149 * m4/m4.m4: Remove.
17150 * tests/Makefile.am: Adjust.
17152 2001-12-10 Akim Demaille <akim@epita.fr>
17154 One structure for states is enough, even though theoretically
17155 there are LR(0) states and LALR(1) states.
17157 * src/lalr.h (state_t): Remove.
17158 (state_table): Be state_t **, not state_t *.
17159 * src/state.h (core, CORE_ALLOC): Rename as...
17160 (state_t, STATE_ALLOC): this.
17161 Add the LALR(1) members: shifts, reductions, errs.
17162 * src/LR0.c (state_table): Rename as...
17163 (state_hash): this, to avoid name clashes with the global
17165 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
17166 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
17168 2001-12-10 Akim Demaille <akim@epita.fr>
17170 Bison dumps core on bash.y.
17171 Reported by Pascal Bart.
17173 * src/warshall.c (bitmatrix_print): New.
17175 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
17176 j must be the outer loop.
17177 * tests/regression.at (Broken Closure): New.
17179 2001-12-05 Akim Demaille <akim@epita.fr>
17181 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
17183 Reported by Peter Hamorsky.
17185 2001-12-05 Akim Demaille <akim@epita.fr>
17187 * src/conflicts.c (err_table): Remove.
17188 (resolve_sr_conflict): Adjust.
17189 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
17191 (state_t.reductions, state_t.shifts): this.
17193 2001-12-05 Akim Demaille <akim@epita.fr>
17195 * src/reduce.c (reduce_grammar_tables): No longer disable the
17196 removal of useless rules via CPP but via `if (0)', so that the
17197 compiler still check the code is valid.
17198 For instance, it should have noticed `rline' no longer exists: use
17199 the `line' member of rule_t.
17200 * src/gram.c (dummy, rline): Remove, unused.
17202 2001-12-05 Akim Demaille <akim@epita.fr>
17204 * src/output.c (pack_vector): Use assert, not berror.
17205 * src/main.c (berror): Remove, unused.
17207 2001-12-05 Akim Demaille <akim@epita.fr>
17209 New experimental feature: if --verbose --trace output all the
17210 items of a state, not only its kernel.
17212 * src/print.c (print_core): If `trace_flag', then invoke closure
17213 before outputting the items of the state (print_core is no longer
17214 a correct name them).
17215 (print_results): Invoke new_closure/free_closure if needed.
17217 2001-12-05 Akim Demaille <akim@epita.fr>
17219 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
17220 * src/closure.c, src/closure.h (itemsetsize): Rename as...
17221 (nitemset): for consistency with the rest of the project.
17223 2001-12-05 Akim Demaille <akim@epita.fr>
17225 * src/closure.c (print_closure): Improve.
17226 (closure): Use it for printing input and output.
17228 2001-12-05 Akim Demaille <akim@epita.fr>
17230 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
17231 indexed by nonterminals.
17233 2001-12-05 Akim Demaille <akim@epita.fr>
17235 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
17237 * src/warshall.h: Remove accidental duplication of the content.
17239 2001-12-05 Akim Demaille <akim@epita.fr>

17251 2001-12-05 Akim Demaille <akim@epita.fr>
17253 * src/output.c (action_row): De-obfuscate
17254 using the good o' techniques: arrays not pointers, variable
17255 locality, BITISSET, RESETBIT etc.
17257 2001-12-05 Akim Demaille <akim@epita.fr>
17259 Pessimize the code to simplify it: from now on, all the states
17260 have a valid SHIFTS, which NSHIFTS is possibly 0.
17262 * src/LR0.c (shifts_new): Be global and move to..
17263 * src/state.c, src/state.h: here.
17264 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
17265 * src/print_graph: Adjust.
17267 2001-12-05 Akim Demaille <akim@epita.fr>
17269 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
17270 * src/conflicts.c: Use it.
17271 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
17272 incorrectly ``simplified''.
17274 2001-12-05 Akim Demaille <akim@epita.fr>
17276 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
17277 using the good o' techniques: arrays not pointers, variable
17278 locality, BITISSET, RESETBIT etc.
17280 2001-12-05 Akim Demaille <akim@epita.fr>
17282 * src/state.h (SHIFT_SYMBOL): New.
17283 * src/conflicts.c: Use it to deobfuscate.
17285 2001-12-05 Akim Demaille <akim@epita.fr>
17287 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
17288 (print_reductions): De-obfuscate using the good o' techniques:
17289 arrays not pointers, variable locality, BITISSET.
17291 2001-12-05 Akim Demaille <akim@epita.fr>
17293 * src/conflicts.c (print_reductions): Arrays, not pointers.
17296 2001-12-05 Akim Demaille <akim@epita.fr>

17304 2001-12-05 Akim Demaille <akim@epita.fr>
17306 * src/conflicts.c (print_reductions): Pessimize, but clarify.
17308 2001-12-05 Akim Demaille <akim@epita.fr>
17310 * src/conflicts.c (print_reductions): Improve variable locality.
17312 2001-12-05 Akim Demaille <akim@epita.fr>
17314 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
17315 * src/lalr.c: Use them.
17317 2001-12-05 Akim Demaille <akim@epita.fr>
17319 * src/LR0.c (augment_automaton): Formatting changes.
17320 Better variable locality.
17322 2001-12-05 Akim Demaille <akim@epita.fr>
17324 * src/lalr.c (matrix_print): New.
17325 (transpose): Use it.
17326 Use arrays instead of pointers.
17328 2001-12-05 Akim Demaille <akim@epita.fr>
17330 * src/lalr.c (maxrhs): Move to...
17331 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
17332 * src/lalr.c (build_relations): Adjust.
17334 2001-12-05 Akim Demaille <akim@epita.fr>
17336 * src/lalr.c (transpose): Free the memory allocated to the
17337 argument, as it is replaced by the results by the unique caller.
17338 (build_relations): Merely invoke transpose: it handles the memory
17340 Improve variable locality.
17341 Avoid variables used as mere abbreviations.
17342 (compute_lookaheads): Use arrays instead of pointers.
17344 2001-12-05 Akim Demaille <akim@epita.fr>
17346 * src/lalr.c (initialize_F): Improve variable locality.
17347 Avoid variables used as mere abbreviations.
17349 2001-12-05 Akim Demaille <akim@epita.fr>
17351 * src/derives.c (print_derives): Display the ruleno.
17352 * src/lalr.c (initialize_F, transpose): Better variable locality
17353 to improve readability.
17354 Avoid variables used as mere abbreviations.

17358 * src/lalr.c (traverse): Use arrays instead of pointers.
17360 2001-12-05 Akim Demaille <akim@epita.fr>
17362 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
17363 the handling of squeue.
17364 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17366 2001-12-05 Akim Demaille <akim@epita.fr>
17368 Because useless nonterminals are now kept alive (instead of being
17369 `destroyed'), we now sometimes examine them, and store information
17370 related to them. Hence we need to know their number, and adjust
17371 memory allocations.
17373 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
17375 * src/LR0.c (allocate_itemsets): The memory allocated to
17376 `symbol_count' was used for two different purpose: once to count
17377 the number of occurrences of each symbol, and later reassigned to
17378 `shift_symbol', containing the symbol that can be shifted from a
17380 Deobfuscate, i.e., allocate, use and free `symbol_count' here
17382 (new_itemsets): Allocate `shift_symbol' here.
17383 (allocate_itemsets): symbol_count includes useless nonterminals.
17384 Make room for them.
17385 (free_storage): Use `free', not `XFREE', for pointers that cannot
17388 2001-12-05 Akim Demaille <akim@epita.fr>
17390 * src/nullable.c (set_nullable): Deobfuscate the handling of
17392 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17394 2001-12-05 Akim Demaille <akim@epita.fr>
17396 * src/gram.c, src/gram.h (ritem_print): New.
17397 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
17398 (This useless function was defined only to work around VMS linkers
17399 that can't handle compilation units with variables only).
17400 * src/reduce.c (dump_grammar): Use it to trace the construction of
17403 2001-12-04 Paul Eggert <eggert@twinsun.com>
17405 * src/bison.simple (union yyalloc): Change member names
17406 to be the same as the stack names.
17407 (yyparse): yyptr is now union yyalloc *, not char *.
17408 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
17409 and may generate better code on some machines.
17410 (yystpcpy): Use prototype if __STDC__ is defined, not just
17411 if __cplusplus is defined.
17413 2001-11-30 Akim Demaille <akim@epita.fr>
17415 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
17416 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
17417 Gettext doesn't compile cleanly, and dies with -Werror.
17418 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
17419 Include WARNING_CFLAGS here.
17420 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
17421 before being defined.
17423 2001-11-27 Paul Eggert <eggert@twinsun.com>
17425 * lib/quotearg.h (quotearg_n, quotearg_n_style):
17426 First arg is int, not unsigned.
17427 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
17428 (SIZE_MAX, UINT_MAX): New macros.
17429 (quotearg_n_options): Abort if N is negative.
17430 Avoid overflow check on hosts where size_t is 64 bits and int
17431 is 32 bits, as overflow is impossible there.
17432 Fix off-by-one typo that caused unnecessary reallocation.
17434 2001-11-29 Paul Eggert <eggert@twinsun.com>
17436 Name space cleanup in generated parser.
17438 * doc/bison.texinfo (Bison Parser): Discuss system headers
17439 and their effect on the user name space.
17441 * src/bison.simple:
17442 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
17443 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
17444 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
17446 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
17447 on user names when possible.
17449 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
17450 Simplify test for whather <alloca.h> exists.
17452 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
17454 (<stdio.h>): Include if YYDEBUG.
17456 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
17457 ! defined (yyoverflow) && ! defined (yymemcpy).
17459 (yymemcpy, yyparse): Rename local variables as needed so that
17460 they all begin with 'yy'.
17462 (yystrlen, yystpcpy): New functions.
17464 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
17467 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
17468 instead of relying on string.h functions. Use YYSTACK_ALLOC
17469 and YYSTACK_FREE instead of malloc and free.
17471 2001-11-30 Akim Demaille <akim@epita.fr>
17473 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
17474 before their first uses.
17475 (YYBISON, YYPURE): Move to the top of the output.
17477 2001-11-30 Akim Demaille <akim@epita.fr>
17479 * tests/reduce.at (Useless Nonterminals): Fix.
17481 2001-11-30 Akim Demaille <akim@epita.fr>
17483 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
17484 if body instead of `;' to pacify GCC's warnings.
17486 2001-11-30 Akim Demaille <akim@epita.fr>
17488 Instead of mapping the LHS of unused rules to -1, keep the LHS
17489 valid, but flag the rules as invalid.
17491 * src/gram.h (rule_t): `useful' is a new member.
17492 * src/print.c (print_grammar): Adjust.
17493 * src/derives.c (set_derives): Likewise.
17494 * src/reader.c (packgram, reduce_output): Likewise.
17495 * src/reduce.c (reduce_grammar_tables): Likewise.
17496 * tests/reduce.at (Underivable Rules, Useless Rules): New.
17498 2001-11-30 Akim Demaille <akim@epita.fr>
17500 * src/reduce.c (reduce_output): Formatting changes.
17501 * src/print.c (print_results, print_grammar): Likewise.
17502 * tests/regression.at (Rule Line Numbers)
17503 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
17505 2001-11-30 Akim Demaille <akim@epita.fr>
17507 * src/reduce.c (nonterminals_reduce): Instead of throwing away
17508 useless nonterminals, move them at the end of the symbol arrays.
17509 (reduce_output): Adjust.
17510 * tests/reduce.at (Useless Nonterminals): Adjust.
17512 2001-11-30 Akim Demaille <akim@epita.fr>
17514 * src/reduce.c: Various comment/formatting changes.
17515 (nonterminals_reduce): New, extracted from...
17516 (reduce_grammar_tables): here.
17517 (reduce_grammar): Call nonterminals_reduce.
17519 2001-11-29 Paul Eggert <eggert@twinsun.com>
17521 * src/bison.simple (YYSTACK_REALLOC): Remove.
17522 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
17523 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
17525 (union yyalloc): New type.
17526 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
17527 an arbitrary restriction on hosts where size_t is wider than int.
17529 (yyparse): Don't dump core if alloca or malloc fails; instead, report
17530 a parser stack overflow. Allocate just one block of memory for all
17531 three stacks, instead of allocating three blocks; this typically is
17532 faster and reduces fragmentation.
17534 Do not limit the number of items in the stack to a value that fits
17535 in 'int', as this is an arbitrary limit on hosts with 64-bit
17536 size_t and 32-bit int.
17538 2001-11-29 Marc Autret <autret_m@epita.fr>
17540 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
17541 of defining YYERROR_VERBOSE.
17542 [AT_DATA]: $4 is now out of C declarations in the prologue.
17544 2001-11-28 Marc Autret <autret_m@epita.fr>

17549 * src/lex.c (literalchar): Become not static.
17551 2001-11-28 Marc Autret <autret_m@epita.fr>
17553 * src/output.h: And put its extern declaration here.
17554 * src/output.c (error_verbose): Define here.
17555 (prepare): Echo name modification.
17556 * src/getargs.h: Clean its extern declaration.
17557 * src/getargs.c (error_verbose_flag): Remove.
17558 (getargs): Remove case 'e'.

19348 New, from fileutils 4.0.37.
19349 * configure.in: Require Autoconf 2.49c. I took some time before

19372 * src/lex.h: Rename all the tokens:
19373 s/\bENDFILE\b/tok_eof/g;
19374 s/\bIDENTIFIER\b/tok_identifier/g;
19376 Let them be enums, not #define, to ease debugging.

19395 * src/files.c (open_files): Don't call `compute_base_names', don't

19400 introduces a guaranteed SEGV for semantic parsers.
19401 * doc/bison.texinfo: Document them.
19402 * tests/suite.at: Exercise these %options.
19404 2000-12-20 Akim Demaille <akim@epita.fr>

19469 (obstack_grow_string): this.
19470 * src/output.c (output_parser): Recognize `%% actions' instead of

19473 * src/bison.hairy: Likewise.

19477 * src/output.c (output_parser): Compute the `#line' lines when

19621 (output_files): this.
19622 Use `obstack_save'.
19623 * src/main.c (main): Don't use `atexit' to register `done', since
19624 it no longer has to remove tmp files, just call `output_files'
19625 when there are no errors.
19627 2000-11-02 Akim Demaille <akim@epita.fr>

19701 (copy_guard): Adjust.
19703 2000-10-16 Akim Demaille <akim@epita.fr>
19705 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

19729 2000-10-04 Akim Demaille <akim@epita.fr>
19731 When a literal string is used to define two different tokens,
19732 `bison -v' segfaults.
19733 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
19735 * tests/regression.m4: New file.
19736 Include the core of the sample provided by Piotr Gackiewicz.
19737 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
19740 2000-10-04 Akim Demaille <akim@epita.fr>

19759 * src/derives.c, src/print.c, src/reduce.c: To ease the
19760 translation, move some `\n' out of the translated strings.
19762 2000-10-02 Akim Demaille <akim@epita.fr>
19764 The location tracking mechanism is precious for parse error
19765 messages. Nevertheless, it is enabled only when `@n' is used in
19766 the grammar, which is a different issue (you can use it in error
19767 message, but not in the grammar per se). Therefore, there should
19768 be another means to enable it.
19770 * src/getargs.c (getargs): Support `--locations'.
19771 (usage): Report it.
19772 * src/getargs.h (locationsflag): Export it.
19773 * src/lex.c (percent_table): Support `%locations'.
19774 * src/reader.c (yylsp_needed): Remove this variable, now replaced
19775 with `locationsflag'.
19776 * doc/bison.texinfo: Document `--locations' and `%locations'.
19778 * tests/calc.m4: Test it.
19780 For regularity of the names, replace each
19781 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
19782 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
19783 In addition replace each `flag' with `_flag'.
19785 2000-10-02 Akim Demaille <akim@epita.fr>
19787 Also test parse error messages, including with YYERROR_VERBOSE.
19789 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
19791 Use it to check the computations.
19792 Use it to check `nonassoc' is honored.
19793 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
19794 `--yyerror-verbose'.

19798 2000-10-02 Akim Demaille <akim@epita.fr>
19800 Test also `--verbose', `--defines' and `--name-prefix'. Testing
19801 the latter demonstrates a flaw in the handling of non debugging
19802 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
19803 was used in order to simplify:
19819 unfortunately this leads to a CPP conflict when
19820 `--name-prefix=foo' is used since it produces `#define yydebug
19823 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
19824 (YYDPRINTF): New macro.
19826 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
19828 Also test `--verbose', `--defines' and `--name-prefix'.

19832 Improve the readability of the produced parsers.
19834 * src/bison.s1: Formatting changes.
19835 Improve the comment related to the `$' mark.
19836 (yydefault): Don't fall through to `yyresume': `goto' there.
19837 * src/output.c (output_parser): When the `$' is met, skip the end
19839 New variable, `number_of_dollar_signs', to check there's exactly
19840 one `$' in the parser skeleton.
19842 2000-10-02 Akim Demaille <akim@epita.fr>
19844 * lib/xstrdup.c: New file, from the fileutils.
19845 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
19846 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
19847 instead of strlen + xmalloc + strcpy.
19848 * src/symtab.c (copys): Remove, use xstrdup instead.
19850 2000-10-02 Akim Demaille <akim@epita.fr>
19852 * src/gram.h (associativity): New enum type which replaces the
19853 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
19854 `right_assoc', `left_assoc' and `non_assoc'.
19855 Adjust all dependencies.
19856 * src/reader.c: Formatting changes.
19857 (LTYPESTR): Don't define it, use it as a literal in
19858 `reader_output_yylsp'.
19859 * src/symtab.h (symbol_class): New enum type which replaces the
19860 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
19861 `sunknown', `stoken and `snterm'.
19863 2000-10-02 Akim Demaille <akim@epita.fr>
19865 * src/getargs.c (fixed_outfiles): Rename as...
19866 (yaccflag): for consistency and accuracy.
19867 Adjust dependencies.
19869 2000-10-02 Akim Demaille <akim@epita.fr>
19871 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
19872 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
19873 difficult and introduced a lot of core dump. It turns out that
19874 Bison used an implementation of `xmalloc' based on `calloc', and
19875 at various places it does depend upon the initialization to 0. I
19876 have not tried to isolate the pertinent places, and all the former
19877 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
19878 someone should address this issue.
19880 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
19881 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

19893 2000-10-02 Akim Demaille <akim@epita.fr>
19895 * src/state.h (nstates, final_state, first_state, first_shift)
19896 (first_reduction): Move their exportation from here...

19898 Adjust dependencies.
19899 * src/getargs.c (statisticsflag): New variable.
19900 Add support for `--statistics'.

19937 Propagate its inclusion.
19938 * src/reduce.c: Topological sort and other formatting changes.
19939 (bool, TRUE, FALSE): Move their definition to...
19940 * src/system.h: here.
19942 2000-10-02 Akim Demaille <akim@epita.fr>
19944 * src/files.c: Formatting changes.
19945 (tryopen, tryclose, openfiles): Rename as...
19946 (xfopen, xfclose, open_files): this.

19971 * src/lalr.c: Formatting changes, topological sorting etc.
19973 2000-10-02 Akim Demaille <akim@epita.fr>
19975 * src/output.c (token_actions): Introduce a temporary array,
19976 YYDEFACT, that makes it possible for this function to use
19977 output_short_table.
19979 2000-10-02 Akim Demaille <akim@epita.fr>
19981 `user_toknums' is output as a `short[]' in `output.c', while it is
19982 defined as a `int[]' in `reader.c'. For consistency with the
19983 other output tables, `user_toknums' is now defined as a table of

20249 There is now a pseudo variable @$ (readble and writable), location
20250 of the lhs of the rule (by default ranging from the location of

20287 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

20966 declaration to allow a multi-character symbol as an alias.
20967 (parse_thong_decl): New function.

20978 Revised and use multiple warnxxx functions to avoid using VARARGS1.
20979 (read_declarations): Improve the error message for
20980 an invalid character. Do not abort.
20981 (read_declarations, copy_guard, copy_action): Use
20982 printable_version to avoid unprintable characters in printed output.

21011 always contain the token. This includes growing the token
21012 buffer while reading an integer.
21013 (parse_percent_token): Replaced if-else statement with percent_table.
21014 (parse_percent_token): Added % declarations as another
21015 way to specify the flags -n, -l, and -r. Also added hooks for
21016 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
21017 major changes to files.c.
21018 (lex) Retain in the incoming stream a character following
21020 (skip_white_space, lex): Revised most error messages
21021 and changed fatal to warn to avoid aborting.
