2289 2002-02-14 Paul Eggert <eggert@twinsun.com>
2291 Remove the support for C++ namespace cleanliness; it was
2292 causing more problems than it was curing, since it didn't work
2293 properly on some nonstandard C++ compilers. This can wait
2294 for a proper C++ parser.
2296 * NEWS: Document this.
2297 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
2298 of C++, as it's treated like C now.

2336 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
2338 * data/bison.c++: Replace some direct m4 expansions by constants. Be
2339 more consistent when naming methods and variables. Put preprocessor
2340 directives around tables only needed for debugging.

2344 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in

2370 More is certainly needed.
2372 2002-02-05 Akim Demaille <akim@epita.fr>
2374 Give a try to M4 as a back end.
2376 * lib/readpipe.c: New, from wdiff.

2379 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
2380 specific values. Now it is m4 that performs the lookup.
2381 * src/parse-skel.y: Remove.

2383 * src/output.c (actions_output, guards_output)

2385 line number, hence remove the second argument.
2386 (guards_output): Check against the guard member of a rule, not the
2389 (output_skeleton): Don't look for the skeleton location, let m4 do
2391 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
2393 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
2394 (prepare): Given that for the time being changesyntax is not
2395 usable in M4, rename the muscles using `-' to `_'.
2396 Define `defines_flag', `output_parser_name' and `output_header_name'.
2397 * src/output.h (actions_output, guards_output)
2398 (token_definitions_output): Adjust prototypes.
2399 * src/scan-skel.l: Instead of scanning the skeletons, it now
2400 processes the output of m4: `__oline__' and `#output'.
2401 * data/bison.simple: Adjust to be used by M4(sugar).
2402 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
2404 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
2405 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
2406 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
2407 shamelessly stolen from CVS Autoconf.
2409 2002-02-05 Akim Demaille <akim@epita.fr>
2411 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
2412 * configure.in: Check for the declarations of free and malloc.
2413 * src/muscle_tab.c: Adjust.
2415 2002-02-05 Akim Demaille <akim@epita.fr>
2417 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
2418 which have no values.
2420 2002-02-05 Akim Demaille <akim@epita.fr>
2422 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
2425 2002-01-29 Paul Eggert <eggert@twinsun.com>
2427 * src/bison.simple (YYSIZE_T): Do not define merely because
2428 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
2429 On some platforms, <alloca.h> does not declare YYSTD (size_t).
2431 2002-01-27 Akim Demaille <akim@epita.fr>
2433 Fix `%nonassoc and eof'.
2435 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
2436 which were not properly copied! Replace
2437 memcpy (res->errs, src->errs, src->nerrs);
2439 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
2441 * tests/regression.at (%nonassoc and eof): Adjust to newest
2442 Autotest: `.' is not in the PATH.
2444 2002-01-27 Akim Demaille <akim@epita.fr>
2446 * tests/sets.at (AT_EXTRACT_SETS): New.
2450 2002-01-26 Akim Demaille <akim@epita.fr>
2452 * tests/actions.at, tests/calc.at, tests/headers.at,
2453 * tests/torture.at: Adjust to the newest Autotest which no longer
2454 forces `.' in the PATH.
2456 2002-01-25 Akim Demaille <akim@epita.fr>
2458 * tests/regression.at (%nonassoc and eof): New.
2459 Suggested by Robert Anisko.
2461 2002-01-24 Akim Demaille <akim@epita.fr>
2463 Bison dumps core when trying to complain about broken input files.
2464 Reported by Cris van Pelt.
2466 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
2467 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
2469 (Invalid inputs): Strengthen: exercise parse_percent_token.
2471 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
2473 * src/Makefile.am: Add bison.c++.
2474 * src/bison.c++: New skeleton.
2476 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
2480 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
2482 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
2484 2002-01-20 Marc Autret <marc@gnu.org>
2486 * src/files.c (compute_output_file_names): Fix
2488 2002-01-20 Marc Autret <marc@gnu.org>
2490 * tests/output.at: New test.
2491 * src/files.c (compute_base_names): Don't map extensions when
2492 the YACC flag is set, use defaults.
2493 Reported by Evgeny Stambulchik.
2495 2002-01-20 Marc Autret <marc@gnu.org>
2497 * src/system.h: Need to define __attribute__ away for non-GCC
2498 compilers as well (i.e. the vendor C compiler).
2499 Suggested by Albert Chin-A-Young.
2501 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
2503 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
2504 canonical definition.
2505 * src/system.h: Use the canonical definition for PARAMS (avoids
2506 a conflict with the macro from lib/hash.h).
2508 2002-01-11 Akim Demaille <akim@epita.fr>
2510 * configure.in: Use AC_FUNC_STRNLEN.
2511 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
2513 2002-01-09 Akim Demaille <akim@epita.fr>
2515 * src/files.c, src/files.h (output_infix): New.
2516 (tab_extension): Remove.
2517 (compute_base_names): Compute the former, drop the latter.

2521 (section.header): Use it.
2522 (section.yacc): Remove.
2523 (prefix): Remove too.

2525 * src/bison.simple, src/bison.hairy: Adjust.
2527 2002-01-09 Akim Demaille <akim@epita.fr>
2529 * configure.in (WERROR_CFLAGS): Compute it.
2530 * src/Makefile.am (CFLAGS): Pass it.
2531 * tests/atlocal.in (CFLAGS): Idem.
2532 * src/files.c: Fix a few warnings.
2533 (get_extension_index): Remove, unused.
2535 2002-01-08 Akim Demaille <akim@epita.fr>

2538 (getargs): Use it to convert DOSish file names.
2539 * src/files.c (base_name): Rename as full_base_name to avoid
2540 clashes with `base_name ()'.
2541 (filename_split): New.
2542 (compute_base_names): N-th rewrite, using filename_split.
2544 2002-01-08 Akim Demaille <akim@epita.fr>
2546 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
2547 New, stolen from the Fileutils 4.1.

2549 * configure.in: Check for the presence of memrchr, and of its
2552 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
2554 * lib/hash.h (__P): Added definition for this macro.
2555 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
2556 BUILT_SOURCES, to ensure they are generated first.
2557 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
2558 %error-verbose to allow bootstrapping with bison 1.30x.
2560 2002-01-06 Akim Demaille <akim@epita.fr>
2562 * src/reader.c (parse_braces): Don't fetch the next char, the
2563 convention is to fetch on entry.
2564 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
2565 'switch' without a following semicolon.
2566 * tests/regression.at (braces parsing): New.
2568 2002-01-06 Akim Demaille <akim@epita.fr>
2570 Bison is dead wrong in its RR conflict reports.
2572 * tests/torture.at (GNU Cim Grammar): New.
2573 * src/conflicts.c (count_rr_conflicts): Fix.
2575 2002-01-06 Akim Demaille <akim@epita.fr>
2577 Creating package.m4 from configure.ac causes too many problems.
2579 * tests/Makefile.am (package.m4): Create it by hand,
2580 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
2582 2002-01-06 Akim Demaille <akim@epita.fr>
2584 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
2587 2002-01-04 Paul Eggert <eggert@twinsun.com>
2589 * doc/bison.texinfo (Debugging):

2595 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
2597 2002-01-03 Akim Demaille <akim@epita.fr>

2600 tracing code to --trace, wait for a better --trace option, with
2603 2002-01-03 Akim Demaille <akim@epita.fr>
2605 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
2606 The ISO C++ standard is extremely clear about it: stderr is
2607 considered a macro, not a regular symbol (see table 94 `Header
2608 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
2609 Therefore std:: does not apply to it. It still does with fprintf.
2610 Also, s/cstdio.h/cstdio/.
2612 2002-01-03 Akim Demaille <akim@epita.fr>
2614 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
2615 for non system headers.
2617 2002-01-02 Akim Demaille <akim@epita.fr>
2619 Equip the skeleton chain with location tracking, runtime trace,
2620 pure parser and scanner.
2622 * src/parse-skel.y: Request a pure parser, locations, and prefix
2624 (%union): Having several members with the same type does not help
2625 type mismatches, simplify.
2626 (YYPRINT, yyprint): New.
2627 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
2630 * src/scan-skel.l: Adjust to these changes.
2631 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
2632 (LOCATION_PRINT, skel_control_t): New.
2634 2001-12-30 Akim Demaille <akim@epita.fr>
2636 * src/parse-skel.y: Get rid of the shift/reduce conflict:
2637 replace `gb' with BLANKS.
2638 * src/scan-skel.l: Adjust.
2640 2001-12-30 Akim Demaille <akim@epita.fr>
2642 * src/system.h: We don't need nor want bcopy.
2643 Throw away MS-DOS crap: we don't need getpid.
2644 * configure.in: We don't need strndup. It was even causing
2645 problems: because Flex includes the headers *before* us,
2646 _GNU_SOURCE is not defined by config.h, and therefore strndup was
2648 * lib/xstrndup.c: New.
2649 * src/scan-skel.l: Use it.
2650 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
2651 * src/parse-skel.y: Use %directives instead of #defines.
2653 2001-12-30 Akim Demaille <akim@epita.fr>
2655 * src/skeleton.h: New.
2656 * src/output.c (output_parser, output_master_parser): Remove, dead
2658 * src/output.h (get_lines_number, actions_output, guards_output)
2659 (token_definitions_output): Prototype them.
2660 * src/parse-skel.y: Add the license notice.
2661 Include output.h and skeleton.h.
2662 (process_skeleton): Returns void, and takes a single parameter.
2663 * src/scan-skel.l: Add the license notice.
2665 Don't use %option yylineno: it seems that then Flex imagines
2666 REJECT has been used, and therefore it won't reallocate its
2667 buffers (which makes no other sense to me than a bug). It results
2668 in warnings for `unused: yy_flex_realloc'.
2670 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
2672 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
2673 (MUSCLE_INSERT_PREFIX): ...to there.
2674 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
2675 (MUSCLE_INSERT_PREFIX): Move from here...
2677 * src/bison.hairy: Add a section directive. Put braces around muscle
2678 names. This parser skeleton is still broken, but Bison should not
2679 choke on a bad muscle 'syntax'.
2680 * src/bison.simple: Add a section directive. Put braces around muscle
2683 * src/files.h (strsuffix, stringappend): Add declarations.
2684 (tab_extension): Add declaration.
2685 (short_base_name): Add declaration.
2687 * src/files.c (strsuffix, stringappend): No longer static. These
2688 functions are used in the skeleton parser.
2689 (tab_extension): New.
2690 (compute_base_names): Use the computations done in this function
2691 to guess if the generated parsers should have '.tab' in their
2693 (short_base_name): No longer static.
2695 * src/output.c (output_skeleton): New.
2696 (output): Disable call to output_master_parser, and give a try to
2697 a new skeleton handling system.
2698 (guards_output, actions_output): No longer static.
2699 (token_definitions_output, get_lines_number): No longer static.
2701 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
2703 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
2706 * src/parse-skel.y: New file.
2707 * src/scan-skel.l: New file.
2709 2001-12-29 Akim Demaille <akim@epita.fr>
2711 %name-prefix is broken.
2713 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
2714 Adjust all dependencies.
2715 * tests/headers.at (export YYLTYPE): Strengthen this test: use
2718 Renaming yylval but not yylloc is not consistent. Now we do.
2720 * src/bison.simple: Prefix yylloc if used.
2721 * doc/bison.texinfo (Decl Summary): Document that.
2723 2001-12-29 Akim Demaille <akim@epita.fr>
2725 * doc/bison.texinfo: Promote `%long-directive' over
2727 Remove all references to fixed-output-files, yacc is enough.
2729 2001-12-29 Akim Demaille <akim@epita.fr>
2731 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
2732 user prologue. These are defaults.
2733 * tests/actions.at (Mid-rule actions): Make sure the user can
2734 define YYDEBUG and YYERROR_VERBOSE.
2736 2001-12-29 Akim Demaille <akim@epita.fr>
2738 * src/output.c (header_output): Don't forget to export YYLTYPE and
2740 * tests/headers.at (export YYLTYPE): New, make sure it does.
2741 * tests/regression.at (%union and --defines, Invalid CPP headers):
2743 * tests/headers.at: here.
2745 2001-12-29 Akim Demaille <akim@epita.fr>
2747 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
2749 2001-12-29 Akim Demaille <akim@epita.fr>
2751 * tests/actions.at (Mid-rule actions): Output on a single line
2754 2001-12-29 Akim Demaille <akim@epita.fr>
2756 * doc/bison.texinfo: Formatting changes.
2758 2001-12-29 Akim Demaille <akim@epita.fr>
2760 Don't store the token defs in a muscle, just be ready to output it
2761 on command. Now possible via `symbols'. Fixes a memory leak.
2763 * src/output.c (token_definitions_output): New.
2764 (output_parser, header_output): Use it.
2765 * src/reader.c (symbols_save): Remove.
2767 2001-12-29 Akim Demaille <akim@epita.fr>
2769 * src/bison.simple: Do not provide a default for YYSTYPE and
2770 YYLTYPE before the user's prologue. Otherwise it's hardly... a
2773 2001-12-29 Akim Demaille <akim@epita.fr>
2775 Mid-rule actions are simply... ignored!
2777 * src/reader.c (readgram): Be sure to attach mid-rule actions to
2778 the empty-rule associated to the dummy symbol, not to the host
2780 * tests/actions.at (Mid-rule actions): New.
2782 2001-12-29 Akim Demaille <akim@epita.fr>
2786 * src/reader.c (reader): Free grammar.
2788 2001-12-29 Akim Demaille <akim@epita.fr>
2792 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
2793 since it allocates it for each state, although only one is needed.
2794 (allocate_storage): Do it here.
2796 2001-12-29 Akim Demaille <akim@epita.fr>
2798 * src/options.h, src/options.c (create_long_option_table): Rename
2800 (long_option_table_new): this, with a clearer prototype.
2801 (percent_table): Remove, unused,
2802 * src/getargs.c (getargs): Adjust.
2804 2001-12-29 Akim Demaille <akim@epita.fr>
2806 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
2807 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
2810 2001-12-29 Akim Demaille <akim@epita.fr>
2812 * src/lalr.c (build_relations): Rename `states' as `states1'.
2813 Sorry, I don't understand exactly what it is, no better name...
2815 2001-12-29 Akim Demaille <akim@epita.fr>
2817 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
2818 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
2819 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
2822 2001-12-29 Akim Demaille <akim@epita.fr>
2824 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
2827 2001-12-29 Akim Demaille <akim@epita.fr>
2829 * src/reader.c, src/reader.h (user_toknums): Remove.
2830 Adjust all users to use symbols[i]->user_token_number.
2832 2001-12-29 Akim Demaille <akim@epita.fr>
2834 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
2835 Adjust all users to use symbols[i]->prec or ->assoc.
2837 2001-12-29 Akim Demaille <akim@epita.fr>
2839 * src/reader.c, src/reader.h (tags): Remove.
2840 Adjust all users to use symbols[i]->tag.
2842 2001-12-29 Akim Demaille <akim@epita.fr>
2844 * src/gram.h, src/gram.c (symbols): New, similar to state_table
2846 * src/reader.c (packsymbols): Fill this table.
2848 * src/conflicts.c (resolve_sr_conflict): Adjust.
2849 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
2851 Use symbols[i]->tag instead of tags[i].
2853 2001-12-29 Akim Demaille <akim@epita.fr>
2855 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
2856 In addition, put a comment in there, to replace...
2857 * tests/regression.at (%union and C comments): Remove.
2859 2001-12-29 Akim Demaille <akim@epita.fr>
2861 * tests/regression.at (Web2c Actions): Blindly move the actual
2862 output as expected output. The contents *seem* right to me, but I
2863 can't pretend reading perfectly parser tables... Nonetheless, all
2864 the other tests pass correctly, the table look OK, even though the
2865 presence of `$axiom' is to be noted: AFAICS it is useless (but
2868 2001-12-29 Akim Demaille <akim@epita.fr>
2870 * src/reader.c (readgram): Don't add the rule 0 if there were no
2871 rules read. In other words, add it _after_ having performed
2872 grammar sanity checks.
2873 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
2875 2001-12-29 Akim Demaille <akim@epita.fr>
2877 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
2878 visible, and some states have now a different number.
2880 2001-12-29 Akim Demaille <akim@epita.fr>
2882 * src/reader.c (readgram): Bind the initial rule's lineno to that
2884 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
2885 (Solved SR Conflicts): Adjust rule 0's line number.
2887 2001-12-29 Akim Demaille <akim@epita.fr>
2889 Fix the `GAWK Grammar' failure.
2891 * src/LR0.c (final_state): Initialize to -1 so that we do compute
2892 the reductions of the first state which was mistakenly confused
2893 with the final state because precisely final_state was initialized
2895 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
2896 now noticed by Bison.
2897 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
2898 have a reduction on $default.
2900 2001-12-29 Akim Demaille <akim@epita.fr>
2902 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
2904 * src/closure.c (print_closure): Likewise.
2905 * src/derives.c (print_derives): Likewise.
2906 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
2909 2001-12-29 Akim Demaille <akim@epita.fr>
2911 * src/lalr.c (lookaheads_print): New.
2912 (lalr): Call it when --trace-flag.
2913 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
2916 2001-12-29 Akim Demaille <akim@epita.fr>
2918 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
2919 when walking through ritem, even via rule->rhs.
2920 * src/reduce.c (dump_grammar, useful_production, reduce_output)
2921 (useful_production, useless_nonterminals): Likewise.
2922 (reduce_grammar_tables): Likewise, plus update nritems.
2923 * src/nullable.c (set_nullable): Likewise.
2924 * src/lalr.c (build_relations): Likewise.
2925 * tests/sets.at (Nullable): Adjust.
2926 Fortunately, now, the $axiom is no longer nullable.
2928 2001-12-29 Akim Demaille <akim@epita.fr>
2930 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
2932 * src/gram.c (ritem_longest_rhs): Likewise.
2933 * src/reduce.c (nonterminals_reduce): Likewise.
2934 * src/print_graph.c (print_graph): Likewise.
2935 * src/output.c (output_rule_data): Likewise.
2936 * src/nullable.c (set_nullable): Likewise.
2938 2001-12-29 Akim Demaille <akim@epita.fr>
2940 * src/output.c: Comment changes.
2942 2001-12-27 Paul Eggert <eggert@twinsun.com>
2944 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
2945 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
2946 Sparc, as they were causing more porting problems than the
2947 (minor) performance improvement was worth.
2949 Also, catch up with 1.31's YYSTD.
2951 2001-12-27 Akim Demaille <akim@epita.fr>
2953 * src/output.c (output_gram): Rely on nritems, not the
2954 0-sentinel. See below.
2955 Use -1 as separator, not 0.
2956 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
2957 Rely on -1 as separator in yyrhs, instead of 0.
2958 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
2959 twice `Now at end of input', therefore there are two lines less to
2962 2001-12-27 Akim Demaille <akim@epita.fr>
2964 * tests/regression.at (Unresolved SR Conflicts):
2965 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
2968 2001-12-27 Akim Demaille <akim@epita.fr>
2970 * src/LR0.c (new_state): Recognize the final state by the fact it
2971 is reached by eoftoken.
2972 (insert_start_shifting_state, insert_eof_shifting_state)
2973 (insert_accepting_state, augment_automaton): Remove, since now
2974 these states are automatically computed from the initial state.
2975 (generate_states): Adjust.
2976 * src/print.c: When reporting a rule number to the user, substract
2977 1, so that the axiom rule is rule 0, and the first user rule is 1.
2978 * src/reduce.c: Likewise.
2979 * src/print_graph.c (print_core): For the time being, just as for
2980 the report, depend upon --trace-flags to dump the full set of
2982 * src/reader.c (readgram): Once the grammar read, insert the rule
2983 0: `$axiom: START-SYMBOL $'.
2984 * tests/set.at: Adjust: rule 0 is now displayed, and since the
2985 number of the states has changed (the final state is no longer
2986 necessarily the last), catch up.
2988 2001-12-27 Akim Demaille <akim@epita.fr>
2990 Try to make the use of the eoftoken valid. Given that its value
2991 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
2992 is used instead of > 0 where appropriate, (ii), depend upon nritems
2993 instead of the 0-sentinel.
2995 * src/gram.h, src/gram.c (nritems): New.
2996 Expected to be duplication of nitems, but for the time being...
2997 * src/reader.c (packgram): Assert nritems and nitems are equal.
2998 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
2999 * src/closure.c (print_closure, print_fderives): Likewise.

3006 * src/main.c (main): If there are complains after grammar
3007 reductions, then output the report anyway if requested, then die.
3008 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
3009 * src/reader.c (eoftoken): New.
3010 (parse_token_decl): If the token being defined has value `0', it
3012 (packsymbols): No longer hack `tags' to insert `$' by hand.
3013 Be sure to preserve the value of the eoftoken.
3014 (reader): Make sure eoftoken is defined.
3015 Initialize nsyms to 0: now eoftoken is created just like the others.
3016 * src/print.c (print_grammar): Don't special case the eof token.
3017 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
3018 lie anyway, albeit pleasant.
3019 * tests/calc.at: Exercise error messages with eoftoken.
3020 Change the grammar so that empty input is invalid.
3021 Adjust expectations.
3022 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
3024 2001-12-27 Akim Demaille <akim@epita.fr>
3026 * configure.in: Check the protos of strchr ans strspn.
3027 Replace strchr if needed.
3028 * src/system.h: Provide the protos of strchr, strspn and memchr if
3030 * lib/strchr.c: New.
3031 * src/reader.c (symbols_save): Use strchr.
3033 2001-12-27 Akim Demaille <akim@epita.fr>
3035 * src/print.c, src/print_graph.c (escape): New.
3036 Use it to quote the TAGS outputs.
3037 * src/print_graph.c (print_state): Now errors are in red, and
3038 reductions in green.
3039 Prefer high to wide: output the state number on a line of its own.
3041 2001-12-27 Akim Demaille <akim@epita.fr>
3043 * src/state.h, src/state.c (reductions_new): New.

3066 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
3067 * src/print.c: here.
3068 (lookaheadset, shiftset): New, used as additional storage by
3070 (print_results): Adjust.
3071 (print_shifts, print_gotos, print_errs): New, extracted from...
3072 (print_actions): here.

3097 * src/output.c (output): Adjust.
3098 * src/reader.c (parse_braces): New, factoring...
3099 (copy_action, copy_guard): these two which are renamed as...
3100 (parse_action, parse_guard): these.
3101 As a voluntary consequence, using braces around guards is now
3104 2001-12-27 Akim Demaille <akim@epita.fr>
3106 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
3107 * src/reader.c (symbol_list): `guard' and `guard_line' are new
3109 (symbol_list_new): Adjust.
3110 (copy_action): action_line is the first line, not the last.
3111 (copy_guard): Just as for actions, store the `action' only, not
3112 the switch/case/break flesh.
3113 Don't parse the user action that might follow the guard, let...
3114 (readgram): do it, i.e., now, there can be an action after a
3116 In other words the guard is just explicitly optional.
3118 * src/output.c (guards_output): New.
3119 (output_parser): Call it when needed.
3120 (output): Also free the guard and attrs obstacks.
3121 * src/files.c, src/files.h (obstack_save): Remove.
3122 (output_files): Remove.
3123 As a result, if one needs the former `.act' file, using an
3124 appropriate skeleton which requires actions and guards is now
3126 * src/main.c (main): Adjust.
3127 * tests/semantic.at: New.
3128 * tests/regression.at: Use `input.y' as input file name.
3129 Avoid 8+3 problems by requiring input.c when the test needs the

3134 * src/reader.c (symbol_list_new): Be sure to initialize all the
3137 2001-12-27 Akim Demaille <akim@epita.fr>
3139 All the hacks using a final pseudo state are now useless.
3141 * src/LR0.c (set_state_table): state_table holds exactly nstates.
3142 * src/lalr.c (nLA): New.
3143 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
3144 instead of lookaheadsp from the pseudo state (nstate + 1).
3146 2001-12-27 Akim Demaille <akim@epita.fr>
3148 * src/output.c (action_row, token_actions): Use a state_t instead
3149 of a integer, and nlookaheads instead of the following state's

3156 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
3157 (conflicts_print, print_reductions): Use a state_t instead of an
3158 integer when referring to a state.
3159 As much as possible, depend upon nlookaheads, instead of the
3160 `lookaheadsp' member of the following state (since lookaheads of
3161 successive states are successive, the difference between state n + 1
3162 and n served as the number of lookaheads for state n).
3163 * src/lalr.c (add_lookback_edge): Likewise.
3164 * src/print.c (print_core, print_actions, print_state)
3165 (print_results): Likewise.
3166 * src/print_graph.c (print_core, print_actions, print_state)
3167 (print_graph): Likewise.
3168 * src/conflicts.h: Adjust.
3170 2001-12-27 Akim Demaille <akim@epita.fr>
3172 * src/bison.hairy: Formatting/comment changes.
3174 Remove `register' indications.
3175 Add plenty of `static'.
3177 2001-12-27 Akim Demaille <akim@epita.fr>
3179 * src/output.c (prepare): Drop the muscle `ntbase' which
3181 * src/bison.simple: Formatting/comment changes.
3182 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
3183 is an undocumented synonym.
3185 2001-12-22 Akim Demaille <akim@epita.fr>
3187 * src/output.c (output_table_data): Change the prototype to use
3188 `int' for array ranges: some invocations do pass an int, not a
3190 Reported by Wayne Green.
3192 2001-12-22 Akim Demaille <akim@epita.fr>
3194 Some actions of web2c.y are improperly triggered.
3195 Reported by Mike Castle.
3197 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
3198 * tests/regression.at (Web2c): Rename as...
3199 (Web2c Report): this.
3200 (Web2c Actions): New.

3204 Reductions in web2c.y are improperly reported.
3205 Reported by Mike Castle.
3207 * src/conflicts.c (print_reductions): Fix.
3208 * tests/regression.at (Web2c): New.
3210 2001-12-18 Akim Demaille <akim@epita.fr>
3212 Some host fail on `assert (!"foo")', which expands to
3213 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
3214 Reported by Nelson Beebee.
3216 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
3217 `#define it_succeeded 0' and `assert (it_succeeded)'.
3219 2001-12-17 Marc Autret <autret_m@epita.fr>
3221 * src/bison.simple: Don't hard code the skeleton line and filename.
3222 * src/output.c (output_parser): Rename 'line' as 'output_line'.
3223 New line counter 'skeleton_line' (skeleton-line muscle).
3225 2001-12-17 Paul Eggert <eggert@twinsun.com>
3227 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
3228 YYDEBUG must be defined to a nonzero value.
3230 * src/bison.simple (yytname): Do not assume that the user defines
3231 YYDEBUG to a properly parenthesized expression.
3233 2001-12-17 Akim Demaille <akim@epita.fr>
3235 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
3236 nlookaheads is a new member.
3238 * src/lalr.h (nlookaheads): Remove this orphan declaration.
3239 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
3242 2001-12-17 Akim Demaille <akim@epita.fr>
3244 * src/files.h, src/files.c (open_files, close_files): Remove.
3245 * src/main.c (main): Don't open/close files, nor invoke lex_free,
3247 * src/reader.c (reader): Do it.
3249 2001-12-17 Akim Demaille <akim@epita.fr>
3251 * src/conflicts.c (print_reductions): Formatting changes.
3253 2001-12-17 Akim Demaille <akim@epita.fr>
3255 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
3256 (flush_reduce): New.
3257 (resolve_sr_conflict): Adjust.
3259 2001-12-17 Akim Demaille <akim@epita.fr>
3261 * src/output.c (output_obstack): Be static and rename as...
3262 (format_obstack): this, to avoid any confusion with files.c's
3264 * src/reader.h (muscle_obstack): Move to...
3265 * src/output.h: here, since it's defined in output.c.
3267 2001-12-17 Akim Demaille <akim@epita.fr>
3269 * src/output.c (action_row, save_column, default_goto)
3270 (sort_actions, matching_state, pack_vector): Better variable
3273 2001-12-17 Akim Demaille <akim@epita.fr>
3275 * src/output.c: Various formatting changes.
3277 2001-12-17 Akim Demaille <akim@epita.fr>
3279 * src/files.c (output_files): Free the output_obstack.
3280 * src/main.c (main): Call print and print_graph conditionally.
3281 * src/print.c (print): Work unconditionally.
3282 * src/print_graph.c (print_graph): Work unconditionally.
3283 * src/conflicts.c (log_resolution): Output only if verbose_flag.
3285 2001-12-16 Marc Autret <autret_m@epita.fr>
3287 * src/output.c (actions_output): Fix. When we use %no-lines,
3288 there is one less line per action.
3290 2001-12-16 Marc Autret <autret_m@epita.fr>
3292 * src/bison.simple: Remove a useless #line directive.
3293 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
3294 * src/output.c (get_lines_number): New.
3295 (output_parser): Adjust, now takes care about the lines of a
3298 (actions_output): Computes the number of lines taken by actions.
3299 (output_master_parser): Insert new skeleton which is the name of
3300 the output parser file name.
3302 2001-12-15 Marc Autret <autret_m@epita.fr>
3304 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
3306 2001-12-15 Marc Autret <autret_m@epita.fr>
3308 * src/output.c (output_gram): Keep track of the hairy one.
3310 2001-12-15 Akim Demaille <akim@epita.fr>
3312 Make `make distcheck' work.
3314 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
3315 system.h which uses libgettext.h.
3317 2001-12-15 Akim Demaille <akim@epita.fr>
3319 * src/nullable.c (set_nullable): Useless rules must be skipped,
3320 otherwise, since we range over their symbols, we might look at a
3321 nonterminal which no longer ``exists'', i.e., it is not counted in
3322 `nvars', hence we overflow our arrays.
3324 2001-12-15 Akim Demaille <akim@epita.fr>
3326 The header can also be produced directly, without any obstack!
3329 * src/files.c, src/files.h (defines_obstack): Remove.
3330 (compute_header_macro): Global.
3331 (defines_obstack_save): Remove.
3332 * src/reader.c (parse_union_decl): No longer output to
3333 defines_obstack: its content can be found in the `stype' muscle
3335 (output_token_translations): Merge into...
3336 (symbols_output): this.
3338 (symbols_save): this.
3340 * src/output.c (header_output): New.
3343 2001-12-15 Akim Demaille <akim@epita.fr>
3345 * src/reader.c (parse_union_decl): Instead of handling two obstack
3346 simultaneously, use one to define the `stype' muscle, and use the
3347 value of the latter to fill defines_obstack.
3348 (copy_comment): Remove.
3349 (copy_comment2): Work for a single obstack.
3351 (copy_comment): this.
3353 2001-12-15 Akim Demaille <akim@epita.fr>
3355 * src/lex.c, src/lex.h (xgetc): No longer static.
3356 * src/reader.c (parse_union_decl): Revamp.
3358 2001-12-15 Akim Demaille <akim@epita.fr>
3360 Still making progress in separating Bison into (i) input, (ii)
3361 process, (iii) output: now we can directly output the parser file
3362 without using table_obstack at all.
3364 * src/files.c, src/files.h (table_obstack): Bye bye.
3365 (parser_file_name): New.
3366 * src/files.c (compute_output_file_names): Compute it.
3367 * src/output.c (actions_output, output_parser)
3368 (output_master_parser): To a file instead of an obstack.
3370 2001-12-15 Akim Demaille <akim@epita.fr>
3372 Attach actions to rules, instead of pre-outputting them to
3375 * src/gram.h (rule_t): action and action_line are new members.
3376 * src/reader.c (symbol_list): Likewise.
3377 (copy_action): Save the actions within the rule.
3378 (packgram): Save them in rule_table.
3379 * src/output.c (actions_output): New.
3380 (output_parser): Use it on `%%actions'.
3381 (output_rule_data): Don't free rule_table.
3383 (prepare): Don't save the `action' muscle.
3384 * src/bison.simple: s/%%action/%%actions/.
3386 2001-12-15 Akim Demaille <akim@epita.fr>
3388 * src/reader.c (copy_action): When --yacc, don't append a `;'
3389 to the user action: let it fail if lacking.
3390 Suggested by Arnold Robbins and Tom Tromey.
3392 2001-12-14 Akim Demaille <akim@epita.fr>
3394 * src/lex.c (literalchar): Simply return the char you decoded, non
3395 longer mess around with obstacks and int pointers.
3398 2001-12-14 Akim Demaille <akim@epita.fr>
3400 * src/lex.c (literalchar): Don't escape the special characters,
3401 just decode them, and keep them as char (before, eol was output as
3402 the 2 char string `\n' etc.).
3403 * src/output.c (output_rule_data): Use quotearg to output the
3406 2001-12-13 Paul Eggert <eggert@twinsun.com>
3408 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
3409 Do not infringe on the global user namespace when using C++.
3410 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
3411 All uses of `fprintf' and `stderr' changed.
3413 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
3415 2001-12-13 Akim Demaille <akim@epita.fr>
3417 The computation of nullable is broken: it doesn't handle empty
3420 * tests/torture.at (GNU AWK Grammar): New.
3421 * tests/sets.at (Nullable): New.
3422 * src/nullable.c (set_nullable): Instead of blindly looping over
3423 `ritems', loop over the rules, and then over their rhs's.
3425 Work around Autotest bugs.
3427 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
3428 frame, because Autotest understand lines starting with a `+' as
3429 traces from the shell. Then, they are not processed properly.
3430 Admittedly an Autotest bug, but we don't have time to wait for
3431 Autotest to catch up.
3432 * tests/regression.at (Broken Closure): Adjust to the new table
3435 * tests/sets.at: here.
3437 2001-12-13 Akim Demaille <akim@epita.fr>
3439 * src/closure.c (closure): Use nrules instead of playing tricks
3442 2001-12-13 Akim Demaille <akim@epita.fr>
3444 * src/print.c (print_actions): Output the handling of `$' as the
3445 traces do: shifting the token EOF. Before EOF was treated as a
3447 * tests/regression.at: Adjust some tests.
3448 * src/print_graph.c (print_core): Complete the set of items via
3449 closure. The next-to-final and final states are still unsatisfying,
3450 but that's to be addressed elsewhere.
3451 No longer output the rule numbers, but do output the state number.
3452 A single loop for the shifts + gotos is enough, but picked a
3453 distinct color for each.
3454 (print_graph): Initialize and finalize closure.
3456 2001-12-13 Akim Demaille <akim@epita.fr>
3458 * src/reader.c (readgram): Remove dead code, an strip useless
3460 (get_type): Remove, unused.
3462 2001-12-12 Akim Demaille <akim@epita.fr>
3464 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
3465 on that of lib/error.c.
3467 2001-12-12 Akim Demaille <akim@epita.fr>
3469 Some hosts don't like `/' in includes.
3471 * src/system.h: Include libgettext.h without qualifying the path.
3472 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
3475 2001-12-11 Marc Autret <autret_m@epita.fr>
3477 * src/output.c (output_parser): Remove useless muscle.
3479 2001-12-11 Marc Autret <autret_m@epita.fr>
3481 * src/bison.simple: Remove #line just before %%epilogue. It
3482 is now handled in ...
3483 * src/reader.c (read_additionnal_code): Add the output of a
3484 #line for the epilogue.
3486 2001-12-10 Marc Autret <autret_m@epita.fr>
3488 * src/reader.c (copy_definition): Re-use CPP-outed code which
3489 replace precedent remove.
3490 * src/bison.simple: Remove #line before %%prologue because
3491 %%input-line is wrong at this time.
3493 2001-12-10 Marc Autret <autret_m@epita.fr>
3495 * src/reader.c (symbols_output): Clean up.
3496 * src/output.c (output_gram, output): Clean up.
3498 2001-12-10 Akim Demaille <akim@epita.fr>
3500 * src/lalr.c (initialize_lookaheads): New. Extracted from...
3501 * src/LR0.c (set_state_table): here.
3502 * src/lalr.c (lalr): Call it.
3504 2001-12-10 Akim Demaille <akim@epita.fr>
3506 * src/state.h (shifts): Remove the `number' member: shifts are
3507 attached to state, hence no longer need to be labelled with a
3510 2001-12-10 Akim Demaille <akim@epita.fr>
3512 Now that states have a complete set of members, the linked list of
3513 shifts is useless: just fill directly the state's shifts member.
3515 * src/state.h (shifts): Remove the `next' member.
3516 * src/LR0.c (first_state, last_state): Remove.
3518 (augment_automaton): Don't look for the shifts that must be added
3519 a shift on EOF: it is those of the state we looked for! But now,
3520 since shifts are attached, it is no longer needed to looking
3521 merely by its id: its number.
3523 2001-12-10 Akim Demaille <akim@epita.fr>
3525 * src/LR0.c (augment_automaton): Better variable locality.
3526 Remove an impossible branch: if there is a state corresponding to
3527 the start symbol being shifted, then there is shift for the start
3528 symbol from the initial state.
3530 2001-12-10 Akim Demaille <akim@epita.fr>
3532 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
3533 only when appropriate: when insert_start_shifting_state' is not
3535 * tests/regression.at (Rule Line Numbers): Adjust.
3537 2001-12-10 Akim Demaille <akim@epita.fr>
3539 * src/LR0.c (augment_automaton): Now that all states have shifts,
3540 merge the two cases addition shifts to the initial state.
3542 2001-12-10 Akim Demaille <akim@epita.fr>
3544 * src/lalr.c (set_state_table): Move to...
3546 * src/lalr.c (lalr): Don't call it...
3547 * src/LR0.c (generate_states): do it.
3548 * src/LR0.h (first_state): Remove, only the table is used.
3550 2001-12-10 Akim Demaille <akim@epita.fr>
3552 * src/LR0.h (first_shift, first_reduction): Remove.
3553 * src/lalr.c: Don't use first_shift: find shifts through the
3556 2001-12-10 Akim Demaille <akim@epita.fr>
3558 * src/LR0.c: Attach shifts to states as soon as they are
3560 * src/lalr.c (set_state_table): Instead of assigning shifts to
3561 state, just assert that the mapping was properly done.
3563 2001-12-10 Akim Demaille <akim@epita.fr>
3565 * src/LR0.c (insert_start_shift): Rename as...
3566 (insert_start_shifting_state): this.
3567 (insert_eof_shifting_state, insert_accepting_state): New.
3568 (augment_automaton): Adjust.
3569 Better locality of the variables.
3570 When looking if the start_symbol is shifted from the initial
3571 state, using `while (... symbol != start_symbol ...)' sounds
3572 better than `while (... symbol < start_symbol ...)': If fail
3573 to see how the order between symbols could be relevant!
3575 2001-12-10 Akim Demaille <akim@epita.fr>
3577 * src/getargs.h: Don't declare `spec_name_prefix' and
3578 `spec_file_prefix', declared by src/files.h.
3579 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
3580 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
3581 * src/output.c (prepare): Adjust.
3582 * src/reader.c (symbols_output): Likewise.
3583 * src/vmsgetargs.c: Vaguely adjust, but who cares?
3585 2001-12-10 Akim Demaille <akim@epita.fr>
3587 * src/muscle_tab.c (muscle_init): NULL is a better default than
3590 2001-12-10 Akim Demaille <akim@epita.fr>
3592 * src/reader.c (reader): Calling symbols_output once is enough.
3594 2001-12-10 Akim Demaille <akim@epita.fr>
3596 Now that states have a complete set of members, the linked list of
3597 reductions is useless: just fill directly the state's reductions
3600 * src/state.h (struct reductions): Remove member `number' and
3602 * src/LR0.c (first_reduction, last_reduction): Remove.
3603 (save_reductions): Don't link the new reductions, store them in
3605 * src/lalr.c (set_state_table): No need to attach reductions to
3606 states, it's already done.
3607 * src/output.c (output_actions): No longer free the shifts, then
3608 the reductions, then the states: free all the states and their
3611 2001-12-10 Akim Demaille <akim@epita.fr>
3613 * src/options.c (OPTN, DRTV, BOTH): New.
3614 (option_table): Use them.
3616 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
3617 the job of system.h.
3618 * src/options.c: Don't include stdio.h and xalloc.h for the same
3621 2001-12-10 Akim Demaille <akim@epita.fr>
3623 * src/output.c (output, prepare): Make sure the values of the
3624 muscles `action' and `prologue' are 0-terminated.
3626 2001-12-10 Akim Demaille <akim@epita.fr>
3628 Clean up GCC warnings.
3630 * src/reader.c (copy_action): `buf' is not used.
3631 (parse_skel_decl): Be static.
3632 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
3633 * src/options.h (create_long_option_table): Have a real prototype.
3634 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
3635 (hash_delete_at): Return const void *.
3636 Adjust casts to preserve the const.
3638 2001-12-10 Akim Demaille <akim@epita.fr>
3640 * configure.in: Require 2.52g.
3641 M4 is not needed, but AUTOM4TE is.
3643 * tests/Makefile.am: Adjust.
3645 2001-12-10 Akim Demaille <akim@epita.fr>
3647 One structure for states is enough, even though theoretically
3648 there are LR(0) states and LALR(1) states.
3650 * src/lalr.h (state_t): Remove.
3651 (state_table): Be state_t **, not state_t *.
3652 * src/state.h (core, CORE_ALLOC): Rename as...
3653 (state_t, STATE_ALLOC): this.
3654 Add the LALR(1) members: shifts, reductions, errs.
3655 * src/LR0.c (state_table): Rename as...
3656 (state_hash): this, to avoid name clashes with the global
3658 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
3659 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
3661 2001-12-10 Akim Demaille <akim@epita.fr>
3663 Bison dumps core on bash.y.
3664 Reported by Pascal Bart.
3666 * src/warshall.c (bitmatrix_print): New.
3668 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
3669 j must be the outer loop.
3670 * tests/regression.at (Broken Closure): New.
3672 2001-12-05 Akim Demaille <akim@epita.fr>
3674 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
3676 Reported by Peter Hámorský.

3680 * src/conflicts.c (err_table): Remove.
3681 (resolve_sr_conflict): Adjust.
3682 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
3684 (state_t.reductions, state_t.shifts): this.
3686 2001-12-05 Akim Demaille <akim@epita.fr>
3688 * src/reduce.c (reduce_grammar_tables): No longer disable the
3689 removal of useless rules via CPP but via `if (0)', so that the
3690 compiler still check the code is valid.
3691 For instance, it should have noticed `rline' no longer exists: use
3692 the `line' member of rule_t.
3693 * src/gram.c (dummy, rline): Remove, unused.
3695 2001-12-05 Akim Demaille <akim@epita.fr>
3697 * src/output.c (pack_vector): Use assert, not berror.
3698 * src/main.c (berror): Remove, unused.
3700 2001-12-05 Akim Demaille <akim@epita.fr>
3702 New experimental feature: if --verbose --trace output all the
3703 items of a state, not only its kernel.
3705 * src/print.c (print_core): If `trace_flag', then invoke closure
3706 before outputting the items of the state (print_core is no longer
3707 a correct name them).

3719 (closure): Use it for printing input and output.
3721 2001-12-05 Akim Demaille <akim@epita.fr>
3723 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
3724 indexed by nonterminals.
3726 2001-12-05 Akim Demaille <akim@epita.fr>
3728 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

3748 locality, BITISSET, RESETBIT etc.
3750 2001-12-05 Akim Demaille <akim@epita.fr>
3752 Pessimize the code to simplify it: from now on, all the states
3753 have a valid SHIFTS, which NSHIFTS is possibly 0.
3755 * src/LR0.c (shifts_new): Be global and move to..
3756 * src/state.c, src/state.h: here.
3757 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

3819 Use arrays instead of pointers.
3821 2001-12-05 Akim Demaille <akim@epita.fr>
3823 * src/lalr.c (maxrhs): Move to...
3824 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
3825 * src/lalr.c (build_relations): Adjust.
3827 2001-12-05 Akim Demaille <akim@epita.fr>
3829 * src/lalr.c (transpose): Free the memory allocated to the
3830 argument, as it is replaced by the results by the unique caller.
3831 (build_relations): Merely invoke transpose: it handles the memory
3833 Improve variable locality.

3853 2001-12-05 Akim Demaille <akim@epita.fr>
3855 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
3856 the handling of squeue.
3857 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
3859 2001-12-05 Akim Demaille <akim@epita.fr>
3861 Because useless nonterminals are now kept alive (instead of being
3862 `destroyed'), we now sometimes examine them, and store information
3863 related to them. Hence we need to know their number, and adjust
3866 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
3868 * src/LR0.c (allocate_itemsets): The memory allocated to
3869 `symbol_count' was used for two different purpose: once to count
3870 the number of occurrences of each symbol, and later reassigned to
3871 `shift_symbol', containing the symbol that can be shifted from a
3873 Deobfuscate, i.e., allocate, use and free `symbol_count' here
3875 (new_itemsets): Allocate `shift_symbol' here.
3876 (allocate_itemsets): symbol_count includes useless nonterminals.
3878 (free_storage): Use `free', not `XFREE', for pointers that cannot
3881 2001-12-05 Akim Demaille <akim@epita.fr>
3883 * src/nullable.c (set_nullable): Deobfuscate the handling of
3885 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
3887 2001-12-05 Akim Demaille <akim@epita.fr>
3889 * src/gram.c, src/gram.h (ritem_print): New.
3890 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
3891 (This useless function was defined only to work around VMS linkers
3892 that can't handle compilation units with variables only).
3893 * src/reduce.c (dump_grammar): Use it to trace the construction of
3896 2001-12-04 Paul Eggert <eggert@twinsun.com>
3898 * src/bison.simple (union yyalloc): Change member names
3899 to be the same as the stack names.
3900 (yyparse): yyptr is now union yyalloc *, not char *.
3901 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
3902 and may generate better code on some machines.
3903 (yystpcpy): Use prototype if __STDC__ is defined, not just
3904 if __cplusplus is defined.
3906 2001-11-30 Akim Demaille <akim@epita.fr>

3912 Include WARNING_CFLAGS here.
3913 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared

3921 (SIZE_MAX, UINT_MAX): New macros.
3922 (quotearg_n_options): Abort if N is negative.
3923 Avoid overflow check on hosts where size_t is 64 bits and int
3924 is 32 bits, as overflow is impossible there.
3925 Fix off-by-one typo that caused unnecessary reallocation.
3927 2001-11-29 Paul Eggert <eggert@twinsun.com>
3929 Name space cleanup in generated parser.
3931 * doc/bison.texinfo (Bison Parser): Discuss system headers
3932 and their effect on the user name space.
3935 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,

3942 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
3943 Simplify test for whather <alloca.h> exists.
3945 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
3947 (<stdio.h>): Include if YYDEBUG.
3949 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
3950 ! defined (yyoverflow) && ! defined (yymemcpy).
3952 (yymemcpy, yyparse): Rename local variables as needed so that
3953 they all begin with 'yy'.
3955 (yystrlen, yystpcpy): New functions.
3957 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
3960 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
3961 instead of relying on string.h functions. Use YYSTACK_ALLOC
3962 and YYSTACK_FREE instead of malloc and free.
3964 2001-11-30 Akim Demaille <akim@epita.fr>
3966 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
3967 before their first uses.

3976 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
3977 if body instead of `;' to pacify GCC's warnings.
3979 2001-11-30 Akim Demaille <akim@epita.fr>
3981 Instead of mapping the LHS of unused rules to -1, keep the LHS
3982 valid, but flag the rules as invalid.
3984 * src/gram.h (rule_t): `useful' is a new member.
3985 * src/print.c (print_grammar): Adjust.
3986 * src/derives.c (set_derives): Likewise.
3987 * src/reader.c (packgram, reduce_output): Likewise.

4016 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
4018 (union yyalloc): New type.
4019 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
4020 an arbitrary restriction on hosts where size_t is wider than int.
4022 (yyparse): Don't dump core if alloca or malloc fails; instead, report
4023 a parser stack overflow. Allocate just one block of memory for all
4024 three stacks, instead of allocating three blocks; this typically is
4025 faster and reduces fragmentation.
4027 Do not limit the number of items in the stack to a value that fits
4028 in 'int', as this is an arbitrary limit on hosts with 64-bit
4029 size_t and 32-bit int.
4031 2001-11-29 Marc Autret <autret_m@epita.fr>
4033 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

4084 2001-11-28 Akim Demaille <akim@epita.fr>
4086 * src/closure.c (closure): Instead of looping over word in array
4087 then bits in words, loop over bits in array.
4089 2001-11-28 Akim Demaille <akim@epita.fr>
4091 * src/closure.c (closure): No longer optimize the special case
4092 where all the bits of `ruleset[r]' are set to 0, to make the code

4097 * src/closure.c (closure): `r' and `c' are new variables, used to
4098 de-obfuscate accesses to RULESET and CORE.

4112 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,

4116 2001-11-27 Paul Eggert <eggert@twinsun.com>
4118 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
4119 use alloca when we didn't want to, and vice versa.

4228 2001-11-23 Akim Demaille <akim@epita.fr>

5877 2001-01-18 Akim Demaille <akim@epita.fr>
5879 Since we now use obstacks, more % directives can be enabled.
5881 * src/lex.c (percent_table): Also accept `%yacc',
5882 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
5884 Handle the actions for `%semantic_parser' and `%pure_parser' here,
5885 instead of returning a token.
5886 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
5887 * src/reader.c (read_declarations): Adjust.
5888 * src/files.c (open_files): Don't call `compute_base_names', don't
5889 compute `attrsfile' since they depend upon data which might be
5890 *in* the input file now.
5891 (output_files): Do it here.
5892 * src/output.c (output_headers): Document the fact that this patch
5893 introduces a guaranteed SEGV for semantic parsers.

5911 * src/files.c (open_files): Fix the computation of short_base_name

5914 2000-12-20 Akim Demaille <akim@epita.fr>
5916 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

5920 2000-12-20 Akim Demaille <akim@epita.fr>
5922 * src/files.c (open_files): Actually the `.output' file is based
5923 on the short_base_name, not base_name.
5924 * tests/suite.at (Checking output file names): Adjust.
5926 2000-12-20 Akim Demaille <akim@epita.fr>

5949 2000-12-19 Akim Demaille <akim@epita.fr>
5951 * src/files.c (strsuffix): New.
5952 (stringappend): Be just like strcat but allocate.

5995 2000-12-19 Akim Demaille <akim@epita.fr>
5997 * src/files.c (open_files): Yipee! We no longer need all the code
5998 looking for `/tmp' since we have no tmp file.

6002 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

6030 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
6031 prevents type checking.
6032 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
6033 cast the value to (void *): assigning a `foo *' to a `void *'

6036 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

6041 * tests/Makefile.am (suite.m4, regression.m4, calc.m4): Rename
6043 (suite.m4, regression.m4, calc.m4): these.
6044 * tests/atgeneral.m4: Update from CVS Autoconf.
6046 2000-11-17 Akim Demaille <akim@epita.fr>
6048 * tests/regression.m4 (%union and --defines): New test,
6049 demonstrating a current bug in the obstack implementation.
6051 2000-11-17 Akim Demaille <akim@epita.fr>
6053 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

6062 2000-11-07 Akim Demaille <akim@epita.fr>
6064 * src: s/Copyright (C)/Copyright/g.

6068 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just

6072 2000-11-07 Akim Demaille <akim@epita.fr>
6074 * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
6075 Merge in a single CPP if/else.
6077 2000-11-07 Akim Demaille <akim@epita.fr>
6079 * src/output.c (output): Remove useless variables.
6080 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
6081 argument `data' for consistency with the prototypes.
6083 (obstack_copy, obstack_copy0): Rename the second argument as
6084 `address' for consistency. Qualify it `const'.
6085 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
6086 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
6087 `const' their input argument (`data' or `address').
6088 Adjust the corresponding macros to include `const' in casts.

6092 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
6093 s/PFILE1/BISON_HAIRY/.

6098 For some reason, this was not applied.
6100 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
6101 `unlink': it's no longer used.
6103 2000-11-03 Akim Demaille <akim@epita.fr>
6105 * src/files.c (skeleton_find): New function, eved out of...
6106 (open_files, open_extra_files): here.
6108 2000-11-03 Akim Demaille <akim@epita.fr>
6112 * src/files.c (obstack_save): New function.
6113 (done): Rename as...
6114 (output_files): this.
6116 * src/main.c (main): Don't use `atexit' to register `done', since
6117 it no longer has to remove tmp files, just call `output_files'
6118 when there are no errors.
6120 2000-11-02 Akim Demaille <akim@epita.fr>
6122 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
6123 `unlink': it's no longer used.
6124 * src/files.h: Formatting changes.

6142 Change each use of `fattrs' into a use of `attrs_obstack'.
6144 * src/reader.c (copy_at): Typo: s/yylloc/yyloc/.
6145 * src/files.c (fattrs): Remove.
6146 (attrs_obstack): New.
6147 Adjust all dependencies.

6150 2000-11-01 Akim Demaille <akim@epita.fr>
6153 Change each use of `faction' into a use of `action_obstack'.

6187 2000-10-16 Akim Demaille <akim@epita.fr>
6189 * src/reader.c (copy_comment2): Expect the input stream to be on
6190 the `/' which is suspected to open a comment, instead of being
6191 called after `//' or `/*' was read.
6192 (copy_comment, copy_definition, parse_union_decl, copy_action)
6193 (copy_guard): Adjust.
6195 2000-10-16 Akim Demaille <akim@epita.fr>
6197 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

6203 (copy_guard, copy_action): Use it.
6205 2000-10-16 Akim Demaille <akim@epita.fr>
6207 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
6208 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
6209 New files, from Fileutils 4.0.27.
6210 * src/main.c (printable_version): Remove.

6217 2000-10-04 Akim Demaille <akim@epita.fr>
6219 * doc/bison.texinfo: Various typos spotted by Neil Booth.
6221 2000-10-04 Akim Demaille <akim@epita.fr>
6223 When a literal string is used to define two different tokens,
6224 `bison -v' segfaults.
6225 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
6227 * tests/regression.m4: New file.
6228 Include the core of the sample provided by Piotr Gackiewicz.
6229 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
6232 2000-10-04 Akim Demaille <akim@epita.fr>
6234 * src/reader.c (parse_expect_decl): Keep `count' within the size
6238 2000-10-02 Paul Eggert <eggert@twinsun.com>

6246 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
6249 2000-10-02 Akim Demaille <akim@epita.fr>
6251 * src/derives.c, src/print.c, src/reduce.c: To ease the
6252 translation, move some `\n' out of the translated strings.
6254 2000-10-02 Akim Demaille <akim@epita.fr>
6256 The location tracking mechanism is precious for parse error
6257 messages. Nevertheless, it is enabled only when `@n' is used in
6258 the grammar, which is a different issue (you can use it in error
6259 message, but not in the grammar per se). Therefore, there should
6260 be another means to enable it.
6262 * src/getargs.c (getargs): Support `--locations'.
6264 * src/getargs.h (locationsflag): Export it.
6265 * src/lex.c (percent_table): Support `%locations'.
6266 * src/reader.c (yylsp_needed): Remove this variable, now replaced
6267 with `locationsflag'.
6268 * doc/bison.texinfo: Document `--locations' and `%locations'.
6270 * tests/calc.m4: Test it.
6272 For regularity of the names, replace each
6273 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
6274 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
6275 In addition replace each `flag' with `_flag'.
6277 2000-10-02 Akim Demaille <akim@epita.fr>
6279 Also test parse error messages, including with YYERROR_VERBOSE.
6281 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
6283 Use it to check the computations.
6284 Use it to check `nonassoc' is honored.
6285 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
6286 `--yyerror-verbose'.
6287 (_AT_CHECK_CALC): Adjust to this option.
6288 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
6290 2000-10-02 Akim Demaille <akim@epita.fr>
6292 Test also `--verbose', `--defines' and `--name-prefix'. Testing
6293 the latter demonstrates a flaw in the handling of non debugging
6294 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
6295 was used in order to simplify:
6311 unfortunately this leads to a CPP conflict when
6312 `--name-prefix=foo' is used since it produces `#define yydebug
6315 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
6316 (YYDPRINTF): New macro.
6318 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
6320 Also test `--verbose', `--defines' and `--name-prefix'.
6322 2000-10-02 Akim Demaille <akim@epita.fr>
6324 Improve the readability of the produced parsers.
6326 * src/bison.s1: Formatting changes.
6327 Improve the comment related to the `$' mark.
6328 (yydefault): Don't fall through to `yyresume': `goto' there.
6329 * src/output.c (output_parser): When the `$' is met, skip the end
6331 New variable, `number_of_dollar_signs', to check there's exactly
6332 one `$' in the parser skeleton.
6334 2000-10-02 Akim Demaille <akim@epita.fr>
6336 * lib/xstrdup.c: New file, from the fileutils.
6337 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
6338 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
6339 instead of strlen + xmalloc + strcpy.
6340 * src/symtab.c (copys): Remove, use xstrdup instead.
6342 2000-10-02 Akim Demaille <akim@epita.fr>
6344 * src/gram.h (associativity): New enum type which replaces the
6345 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
6346 `right_assoc', `left_assoc' and `non_assoc'.
6347 Adjust all dependencies.
6348 * src/reader.c: Formatting changes.
6349 (LTYPESTR): Don't define it, use it as a literal in
6350 `reader_output_yylsp'.
6351 * src/symtab.h (symbol_class): New enum type which replaces the
6352 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
6353 `sunknown', `stoken and `snterm'.
6355 2000-10-02 Akim Demaille <akim@epita.fr>
6357 * src/getargs.c (fixed_outfiles): Rename as...
6358 (yaccflag): for consistency and accuracy.
6359 Adjust dependencies.
6361 2000-10-02 Akim Demaille <akim@epita.fr>
6363 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
6364 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
6365 difficult and introduced a lot of core dump. It turns out that
6366 Bison used an implementation of `xmalloc' based on `calloc', and
6367 at various places it does depend upon the initialization to 0. I
6368 have not tried to isolate the pertinent places, and all the former
6369 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
6370 someone should address this issue.
6372 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
6373 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

6385 2000-10-02 Akim Demaille <akim@epita.fr>
6387 * src/state.h (nstates, final_state, first_state, first_shift)
6388 (first_reduction): Move their exportation from here...
6389 * src/LR0.h: to here.
6390 Adjust dependencies.
6391 * src/getargs.c (statisticsflag): New variable.
6392 Add support for `--statistics'.
6393 Adjust dependencies.
6395 Remove a lot of now useless `extern' statements in most files.
6397 2000-10-02 Akim Demaille <akim@epita.fr>
6399 * src/LR0.h: New file.
6402 2000-10-02 Akim Demaille <akim@epita.fr>

7506 (parse_percent_token): Added % declarations as another
7507 way to specify the flags -n, -l, and -r. Also added hooks for
7508 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
7509 major changes to files.c.
7510 (lex) Retain in the incoming stream a character following
7512 (skip_white_space, lex): Revised most error messages
7513 and changed fatal to warn to avoid aborting.
