 235
 236         Remove the support for C++ namespace cleanliness; it was
 237         causing more problems than it was curing, since it didn't work
 238         properly on some nonstandard C++ compilers.  This can wait
 239         for a proper C++ parser.

 250

 280
 281 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 282
 283         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
 284         more consistent when naming methods and variables.  Put preprocessor
 285         directives around tables only needed for debugging.
 286
 287 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>

 329         (token_definitions_output): No longer keeps track of the output
 330         line number, hence remove the second argument.
 331         (guards_output): Check against the guard member of a rule, not the
 332         action member.
 333         Adjust callers.
 334         (output_skeleton): Don't look for the skeleton location, let m4 do
 335         that.
 336         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
 337         file will be used.
 338         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
 339         (prepare): Given that for the time being changesyntax is not
 340         usable in M4, rename the muscles using `-' to `_'.
 341         Define `defines_flag', `output_parser_name' and `output_header_name'.

 346         * data/bison.simple: Adjust to be used by M4(sugar).
 347         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
 348         to date.
 349         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
 350         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
 351         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
 352         shamelessly stolen from CVS Autoconf.

 371
 372         * src/bison.simple (YYSIZE_T): Do not define merely because
 373         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 374         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 375
 376 2002-01-27  Akim Demaille  <akim@epita.fr>
 377
 378         Fix `%nonassoc and eof'.
 379
 380         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
 381         which were not properly copied!  Replace
 382         memcpy (res->errs, src->errs, src->nerrs);
 383         with
 384         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
 385         !!!
 386         * tests/regression.at (%nonassoc and eof): Adjust to newest
 387         Autotest: `.' is not in the PATH.
 388
 389 2002-01-27  Akim Demaille  <akim@epita.fr>
 390
 391         * tests/sets.at (AT_EXTRACT_SETS): New.
 392         (Nullable): Use it.
 393         (Firsts): New.
 394
 395 2002-01-26  Akim Demaille  <akim@epita.fr>
 396
 397         * tests/actions.at, tests/calc.at, tests/headers.at,
 398         * tests/torture.at: Adjust to the newest Autotest which no longer
 399         forces `.' in the PATH.
 400
 401 2002-01-25  Akim Demaille  <akim@epita.fr>
 402
 403         * tests/regression.at (%nonassoc and eof): New.
 404         Suggested by Robert Anisko.

 406 2002-01-24  Akim Demaille  <akim@epita.fr>
 407
 408         Bison dumps core when trying to complain about broken input files.
 409         Reported by Cris van Pelt.
 410
 411         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
 412         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
 413         into...
 414         (Invalid inputs): Strengthen: exercise parse_percent_token.
 415
 416 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
 417
 418         * src/Makefile.am: Add bison.c++.
 419         * src/bison.c++: New skeleton.
 420
 421 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
 422
 423         * po/it.po: New.
 424
 425 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
 426
 427         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
 428
 429 2002-01-20  Marc Autret  <marc@gnu.org>
 430
 431         * src/files.c (compute_output_file_names): Fix
 432
 433 2002-01-20  Marc Autret  <marc@gnu.org>
 434
 435         * tests/output.at: New test.
 436         * src/files.c (compute_base_names): Don't map extensions when
 437         the YACC flag is set, use defaults.
 438         Reported by Evgeny Stambulchik.
 439
 440 2002-01-20  Marc Autret  <marc@gnu.org>
 441
 442         * src/system.h: Need to define __attribute__ away for non-GCC
 443         compilers as well (i.e. the vendor C compiler).
 444         Suggested by Albert Chin-A-Young.
 445
 446 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
 447
 448         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
 449         canonical definition.
 450         * src/system.h: Use the canonical definition for PARAMS (avoids
 451         a conflict with the macro from lib/hash.h).
 452
 453 2002-01-11  Akim Demaille  <akim@epita.fr>
 454
 455         * configure.in: Use AC_FUNC_STRNLEN.
 456         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
 457
 458 2002-01-09  Akim Demaille  <akim@epita.fr>
 459
 460         * src/files.c, src/files.h (output_infix): New.
 461         (tab_extension): Remove.
 462         (compute_base_names): Compute the former, drop the latter.
 463         * src/output.c (prepare): Insert the muscles `output-infix', and
 464         `output-suffix'.
 465         * src/parse-skel.y (string, string.1): New.
 466         (section.header): Use it.
 467         (section.yacc): Remove.
 468         (prefix): Remove too.
 469         * src/scan-skel.l: Adjust.
 470         * src/bison.simple, src/bison.hairy: Adjust.
 471
 472 2002-01-09  Akim Demaille  <akim@epita.fr>
 473
 474         * configure.in (WERROR_CFLAGS): Compute it.
 475         * src/Makefile.am (CFLAGS): Pass it.
 476         * tests/atlocal.in (CFLAGS): Idem.
 477         * src/files.c: Fix a few warnings.
 478         (get_extension_index): Remove, unused.
 479
 480 2002-01-08  Akim Demaille  <akim@epita.fr>
 481
 482         * src/getargs.c (AS_FILE_NAME): New.
 483         (getargs): Use it to convert DOSish file names.
 484         * src/files.c (base_name): Rename as full_base_name to avoid
 485         clashes with `base_name ()'.
 486         (filename_split): New.
 487         (compute_base_names): N-th rewrite, using filename_split.
 488
 489 2002-01-08  Akim Demaille  <akim@epita.fr>
 490
 491         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
 492         New, stolen from the Fileutils 4.1.
 493         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
 494         * configure.in: Check for the presence of memrchr, and of its
 495         prototype.
 496
 497 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
 498
 499         * lib/hash.h (__P): Added definition for this macro.
 500         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
 501         BUILT_SOURCES, to ensure they are generated first.
 502         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
 503         %error-verbose to allow bootstrapping with bison 1.30x.
 504
 505 2002-01-06  Akim Demaille  <akim@epita.fr>
 506
 507         * src/reader.c (parse_braces): Don't fetch the next char, the
 508         convention is to fetch on entry.
 509         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
 510         'switch' without a following semicolon.
 511         * tests/regression.at (braces parsing): New.
 512
 513 2002-01-06  Akim Demaille  <akim@epita.fr>
 514
 515         Bison is dead wrong in its RR conflict reports.
 516
 517         * tests/torture.at (GNU Cim Grammar): New.
 518         * src/conflicts.c (count_rr_conflicts): Fix.
 519
 520 2002-01-06  Akim Demaille  <akim@epita.fr>
 521
 522         Creating package.m4 from configure.ac causes too many problems.
 523
 524         * tests/Makefile.am (package.m4): Create it by hand,
 525         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
 526
 527 2002-01-06  Akim Demaille  <akim@epita.fr>
 528
 529         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
 530         skeleton.h.
 531
 532 2002-01-04  Paul Eggert  <eggert@twinsun.com>
 533
 534         * doc/bison.texinfo (Debugging):
 535         Remove YYSTDERR; it's no longer defined or used.
 536         Also, s/cstdio.h/cstdio/.
 537
 538 2002-01-03  Akim Demaille  <akim@epita.fr>
 539
 540         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
 541
 542 2002-01-03  Akim Demaille  <akim@epita.fr>
 543
 544         * src/parse-skel.y (process_skeleton): Don't bind the parser's
 545         tracing code to --trace, wait for a better --trace option, with
 546         args.
 547
 548 2002-01-03  Akim Demaille  <akim@epita.fr>
 549
 550         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
 551         The ISO C++ standard is extremely clear about it: stderr is
 552         considered a macro, not a regular symbol (see table 94 `Header
 553         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
 554         Therefore std:: does not apply to it.  It still does with fprintf.
 555         Also, s/cstdio.h/cstdio/.
 556
 557 2002-01-03  Akim Demaille  <akim@epita.fr>
 558
 559         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
 560         for non system headers.
 561
 562 2002-01-02  Akim Demaille  <akim@epita.fr>
 563
 564         Equip the skeleton chain with location tracking, runtime trace,
 565         pure parser and scanner.
 566
 567         * src/parse-skel.y: Request a pure parser, locations, and prefix
 568         renaming.
 569         (%union): Having several members with the same type does not help
 570         type mismatches, simplify.
 571         (YYPRINT, yyprint): New.
 572         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
 573         (skel_error): this.
 574         Handle locations.
 575         * src/scan-skel.l: Adjust to these changes.
 576         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
 577         (LOCATION_PRINT, skel_control_t): New.
 578
 579 2001-12-30  Akim Demaille  <akim@epita.fr>
 580
 581         * src/parse-skel.y: Get rid of the shift/reduce conflict:
 582         replace `gb' with BLANKS.
 583         * src/scan-skel.l: Adjust.
 584
 585 2001-12-30  Akim Demaille  <akim@epita.fr>
 586
 587         * src/system.h: We don't need nor want bcopy.
 588         Throw away MS-DOS crap: we don't need getpid.
 589         * configure.in: We don't need strndup.  It was even causing
 590         problems: because Flex includes the headers *before* us,
 591         _GNU_SOURCE is not defined by config.h, and therefore strndup was
 592         not visible.
 593         * lib/xstrndup.c: New.
 594         * src/scan-skel.l: Use it.
 595         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
 596         * src/parse-skel.y: Use %directives instead of #defines.
 597
 598 2001-12-30  Akim Demaille  <akim@epita.fr>
 599
 600         * src/skeleton.h: New.
 601         * src/output.c (output_parser, output_master_parser): Remove, dead
 602         code.
 603         * src/output.h (get_lines_number, actions_output, guards_output)
 604         (token_definitions_output): Prototype them.
 605         * src/parse-skel.y: Add the license notice.
 606         Include output.h and skeleton.h.
 607         (process_skeleton): Returns void, and takes a single parameter.
 608         * src/scan-skel.l: Add the license notice.
 609         Include skeleton.h.
 610         Don't use %option yylineno: it seems that then Flex imagines
 611         REJECT has been used, and therefore it won't reallocate its
 612         buffers (which makes no other sense to me than a bug).  It results
 613         in warnings for `unused: yy_flex_realloc'.
 614
 615 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
 616
 617         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 618         (MUSCLE_INSERT_PREFIX): ...to there.
 619         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 620         (MUSCLE_INSERT_PREFIX): Move from here...
 621
 622         * src/bison.hairy: Add a section directive.  Put braces around muscle
 623         names.  This parser skeleton is still broken, but Bison should not
 624         choke on a bad muscle 'syntax'.
 625         * src/bison.simple: Add a section directive.  Put braces around muscle
 626         names.
 627
 628         * src/files.h (strsuffix, stringappend): Add declarations.
 629         (tab_extension): Add declaration.
 630         (short_base_name): Add declaration.
 631
 632         * src/files.c (strsuffix, stringappend): No longer static.  These
 633         functions are used in the skeleton parser.
 634         (tab_extension): New.
 635         (compute_base_names): Use the computations done in this function
 636         to guess if the generated parsers should have '.tab' in their
 637         names.
 638         (short_base_name): No longer static.
 639
 640         * src/output.c (output_skeleton): New.
 641         (output): Disable call to output_master_parser, and give a try to
 642         a new skeleton handling system.
 643         (guards_output, actions_output): No longer static.
 644         (token_definitions_output, get_lines_number): No longer static.
 645
 646         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
 647
 648         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
 649         parse-skel.y.
 650
 651         * src/parse-skel.y: New file.
 652         * src/scan-skel.l: New file.
 653
 654 2001-12-29  Akim Demaille  <akim@epita.fr>
 655
 656         %name-prefix is broken.
 657
 658         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
 659         Adjust all dependencies.
 660         * tests/headers.at (export YYLTYPE): Strengthen this test: use
 661         %name-prefix.
 662
 663         Renaming yylval but not yylloc is not consistent.  Now we do.
 664
 665         * src/bison.simple: Prefix yylloc if used.
 666         * doc/bison.texinfo (Decl Summary): Document that.
 667
 668 2001-12-29  Akim Demaille  <akim@epita.fr>
 669
 670         * doc/bison.texinfo: Promote `%long-directive' over
 671         `%long_directive'.
 672         Remove all references to fixed-output-files, yacc is enough.
 673
 674 2001-12-29  Akim Demaille  <akim@epita.fr>
 675
 676         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
 677         user prologue.  These are defaults.
 678         * tests/actions.at (Mid-rule actions): Make sure the user can
 679         define YYDEBUG and YYERROR_VERBOSE.
 680
 681 2001-12-29  Akim Demaille  <akim@epita.fr>
 682
 683         * src/output.c (header_output): Don't forget to export YYLTYPE and
 684         yylloc.
 685         * tests/headers.at (export YYLTYPE): New, make sure it does.
 686         * tests/regression.at (%union and --defines, Invalid CPP headers):
 687         Move to...
 688         * tests/headers.at: here.
 689
 690 2001-12-29  Akim Demaille  <akim@epita.fr>
 691
 692         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
 693
 694 2001-12-29  Akim Demaille  <akim@epita.fr>
 695
 696         * tests/actions.at (Mid-rule actions): Output on a single line
 697         instead of several.
 698
 699 2001-12-29  Akim Demaille  <akim@epita.fr>
 700
 701         * doc/bison.texinfo: Formatting changes.
 702
 703 2001-12-29  Akim Demaille  <akim@epita.fr>
 704
 705         Don't store the token defs in a muscle, just be ready to output it
 706         on command.  Now possible via `symbols'.  Fixes a memory leak.
 707
 708         * src/output.c (token_definitions_output): New.
 709         (output_parser, header_output): Use it.
 710         * src/reader.c (symbols_save): Remove.
 711
 712 2001-12-29  Akim Demaille  <akim@epita.fr>
 713
 714         * src/bison.simple: Do not provide a default for YYSTYPE and
 715         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
 716         default.
 717
 718 2001-12-29  Akim Demaille  <akim@epita.fr>
 719
 720         Mid-rule actions are simply... ignored!
 721
 722         * src/reader.c (readgram): Be sure to attach mid-rule actions to
 723         the empty-rule associated to the dummy symbol, not to the host
 724         rule.
 725         * tests/actions.at (Mid-rule actions): New.
 726
 727 2001-12-29  Akim Demaille  <akim@epita.fr>
 728
 729         Memory leak.
 730
 731         * src/reader.c (reader): Free grammar.
 732
 733 2001-12-29  Akim Demaille  <akim@epita.fr>
 734
 735         Memory leak.
 736
 737         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
 738         since it allocates it for each state, although only one is needed.
 739         (allocate_storage): Do it here.
 740
 741 2001-12-29  Akim Demaille  <akim@epita.fr>
 742
 743         * src/options.h, src/options.c (create_long_option_table): Rename
 744         as...
 745         (long_option_table_new): this, with a clearer prototype.
 746         (percent_table): Remove, unused,
 747         * src/getargs.c (getargs): Adjust.
 748
 749 2001-12-29  Akim Demaille  <akim@epita.fr>

 751         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
 752         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 753         as states.
 754
 755 2001-12-29  Akim Demaille  <akim@epita.fr>
 756
 757         * src/lalr.c (build_relations): Rename `states' as `states1'.
 758         Sorry, I don't understand exactly what it is, no better name...
 759
 760 2001-12-29  Akim Demaille  <akim@epita.fr>
 761
 762         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 763         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 764         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 765         as rules.
 766
 767 2001-12-29  Akim Demaille  <akim@epita.fr>
 768
 769         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 770         ago.
 771
 772 2001-12-29  Akim Demaille  <akim@epita.fr>
 773
 774         * src/reader.c, src/reader.h (user_toknums): Remove.
 775         Adjust all users to use symbols[i]->user_token_number.
 776
 777 2001-12-29  Akim Demaille  <akim@epita.fr>
 778
 779         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 780         Adjust all users to use symbols[i]->prec or ->assoc.
 781
 782 2001-12-29  Akim Demaille  <akim@epita.fr>
 783
 784         * src/reader.c, src/reader.h (tags): Remove.
 785         Adjust all users to use symbols[i]->tag.
 786
 787 2001-12-29  Akim Demaille  <akim@epita.fr>
 788
 789         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 790         and rule_table.
 791         * src/reader.c (packsymbols): Fill this table.
 792         Drop sprec.
 793         * src/conflicts.c (resolve_sr_conflict): Adjust.
 794         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 795         single table.
 796         Use symbols[i]->tag instead of tags[i].
 797
 798 2001-12-29  Akim Demaille  <akim@epita.fr>
 799
 800         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 801         In addition, put a comment in there, to replace...
 802         * tests/regression.at (%union and C comments): Remove.
 803
 804 2001-12-29  Akim Demaille  <akim@epita.fr>
 805
 806         * tests/regression.at (Web2c Actions): Blindly move the actual
 807         output as expected output.  The contents *seem* right to me, but I
 808         can't pretend reading perfectly parser tables...  Nonetheless, all
 809         the other tests pass correctly, the table look OK, even though the
 810         presence of `$axiom' is to be noted: AFAICS it is useless (but
 811         harmless).
 812
 813 2001-12-29  Akim Demaille  <akim@epita.fr>
 814
 815         * src/reader.c (readgram): Don't add the rule 0 if there were no
 816         rules read.  In other words, add it _after_ having performed
 817         grammar sanity checks.
 818         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 819
 820 2001-12-29  Akim Demaille  <akim@epita.fr>
 821
 822         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 823         visible, and some states have now a different number.
 824
 825 2001-12-29  Akim Demaille  <akim@epita.fr>
 826
 827         * src/reader.c (readgram): Bind the initial rule's lineno to that
 828         of the first rule.
 829         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 830         (Solved SR Conflicts): Adjust rule 0's line number.
 831
 832 2001-12-29  Akim Demaille  <akim@epita.fr>
 833
 834         Fix the `GAWK Grammar' failure.
 835
 836         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 837         the reductions of the first state which was mistakenly confused
 838         with the final state because precisely final_state was initialized
 839         to 0.
 840         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 841         now noticed by Bison.
 842         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 843         have a reduction on $default.
 844
 845 2001-12-29  Akim Demaille  <akim@epita.fr>
 846
 847         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 848         rule line numbers.
 849         * src/closure.c (print_closure): Likewise.
 850         * src/derives.c (print_derives): Likewise.
 851         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 852         now.
 853
 854 2001-12-29  Akim Demaille  <akim@epita.fr>
 855
 856         * src/lalr.c (lookaheads_print): New.
 857         (lalr): Call it when --trace-flag.
 858         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 859         are dumped.
 860
 861 2001-12-29  Akim Demaille  <akim@epita.fr>
 862
 863         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 864         when walking through ritem, even via rule->rhs.
 865         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 866         (useful_production, useless_nonterminals): Likewise.
 867         (reduce_grammar_tables): Likewise, plus update nritems.
 868         * src/nullable.c (set_nullable): Likewise.
 869         * src/lalr.c (build_relations): Likewise.
 870         * tests/sets.at (Nullable): Adjust.
 871         Fortunately, now, the $axiom is no longer nullable.
 872
 873 2001-12-29  Akim Demaille  <akim@epita.fr>
 874
 875         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 876         the 0-sentinel.
 877         * src/gram.c (ritem_longest_rhs): Likewise.
 878         * src/reduce.c (nonterminals_reduce): Likewise.
 879         * src/print_graph.c (print_graph): Likewise.
 880         * src/output.c (output_rule_data): Likewise.
 881         * src/nullable.c (set_nullable):  Likewise.
 882
 883 2001-12-29  Akim Demaille  <akim@epita.fr>
 884
 885         * src/output.c: Comment changes.
 886
 887 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 888
 889         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 890         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 891         Sparc, as they were causing more porting problems than the
 892         (minor) performance improvement was worth.
 893
 894         Also, catch up with 1.31's YYSTD.
 895
 896 2001-12-27  Akim Demaille  <akim@epita.fr>
 897
 898         * src/output.c (output_gram): Rely on nritems, not the
 899         0-sentinel.  See below.
 900         Use -1 as separator, not 0.
 901         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 902         Rely on -1 as separator in yyrhs, instead of 0.
 903         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 904         twice `Now at end of input', therefore there are two lines less to
 905         expect.
 906
 907 2001-12-27  Akim Demaille  <akim@epita.fr>
 908
 909         * tests/regression.at (Unresolved SR Conflicts):
 910         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 911         below.
 912
 913 2001-12-27  Akim Demaille  <akim@epita.fr>
 914
 915         * src/LR0.c (new_state): Recognize the final state by the fact it
 916         is reached by eoftoken.
 917         (insert_start_shifting_state, insert_eof_shifting_state)
 918         (insert_accepting_state, augment_automaton): Remove, since now
 919         these states are automatically computed from the initial state.
 920         (generate_states): Adjust.
 921         * src/print.c: When reporting a rule number to the user, substract
 922         1, so that the axiom rule is rule 0, and the first user rule is 1.
 923         * src/reduce.c: Likewise.
 924         * src/print_graph.c (print_core): For the time being, just as for
 925         the report, depend upon --trace-flags to dump the full set of
 926         items.
 927         * src/reader.c (readgram): Once the grammar read, insert the rule
 928         0: `$axiom: START-SYMBOL $'.
 929         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 930         number of the states has changed (the final state is no longer
 931         necessarily the last), catch up.
 932
 933 2001-12-27  Akim Demaille  <akim@epita.fr>
 934
 935         Try to make the use of the eoftoken valid.  Given that its value
 936         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 937         is used instead of > 0 where appropriate, (ii), depend upon nritems
 938         instead of the 0-sentinel.
 939
 940         * src/gram.h, src/gram.c (nritems): New.
 941         Expected to be duplication of nitems, but for the time being...
 942         * src/reader.c (packgram): Assert nritems and nitems are equal.
 943         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 944         * src/closure.c (print_closure, print_fderives): Likewise.
 945         * src/gram.c (ritem_print): Likewise.
 946         * src/print.c (print_core, print_grammar): Likewise.
 947         * src/print_graph.c: Likewise.
 948
 949 2001-12-27  Akim Demaille  <akim@epita.fr>
 950
 951         * src/main.c (main): If there are complains after grammar
 952         reductions, then output the report anyway if requested, then die.
 953         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 954         * src/reader.c (eoftoken): New.
 955         (parse_token_decl): If the token being defined has value `0', it
 956         is the eoftoken.
 957         (packsymbols): No longer hack `tags' to insert `$' by hand.
 958         Be sure to preserve the value of the eoftoken.
 959         (reader): Make sure eoftoken is defined.
 960         Initialize nsyms to 0: now eoftoken is created just like the others.
 961         * src/print.c (print_grammar): Don't special case the eof token.
 962         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 963         lie anyway, albeit pleasant.
 964         * tests/calc.at: Exercise error messages with eoftoken.
 965         Change the grammar so that empty input is invalid.
 966         Adjust expectations.
 967         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 968
 969 2001-12-27  Akim Demaille  <akim@epita.fr>
 970
 971         * configure.in: Check the protos of strchr ans strspn.
 972         Replace strchr if needed.
 973         * src/system.h: Provide the protos of strchr, strspn and memchr if
 974         missing.
 975         * lib/strchr.c: New.
 976         * src/reader.c (symbols_save): Use strchr.
 977
 978 2001-12-27  Akim Demaille  <akim@epita.fr>
 979
 980         * src/print.c, src/print_graph.c (escape): New.
 981         Use it to quote the TAGS outputs.
 982         * src/print_graph.c (print_state): Now errors are in red, and
 983         reductions in green.
 984         Prefer high to wide: output the state number on a line of its own.
 985
 986 2001-12-27  Akim Demaille  <akim@epita.fr>
 987
 988         * src/state.h, src/state.c (reductions_new): New.
 989         * src/LR0.c (set_state_table): Let all the states have a
 990         `reductions', even if reduced to 0.
 991         (save_reductions): Adjust.
 992         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 993         * src/print.c (print_reductions, print_actions): Adjust.
 994         * src/output.c (action_row): Adjust.
 995
 996 2001-12-27  Akim Demaille  <akim@epita.fr>
 997
 998         * src/state.h, src/state.c (errs_new, errs_dup): New.
 999         * src/LR0.c (set_state_table): Let all the states have an errs,
1000         even if reduced to 0.
1001         * src/print.c (print_errs, print_reductions): Adjust.
1002         * src/output.c (output_actions, action_row): Adjust.
1003         * src/conflicts.c (resolve_sr_conflict): Adjust.
1004
1005 2001-12-27  Akim Demaille  <akim@epita.fr>
1006
1007         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
1008
1009 2001-12-27  Akim Demaille  <akim@epita.fr>
1010
1011         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
1012         * src/print.c: here.
1013         (lookaheadset, shiftset): New, used as additional storage by
1014         print_reductions.
1015         (print_results): Adjust.
1016         (print_shifts, print_gotos, print_errs): New, extracted from...
1017         (print_actions): here.
1018         * src/print_graph.c (print_actions): Remove dead code.
1019
1020 2001-12-27  Akim Demaille  <akim@epita.fr>
1021
1022         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
1023         `$n' and `@n'.
1024
1025 2001-12-27  Akim Demaille  <akim@epita.fr>
1026
1027         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
1028         (build_relations): Adjust.
1029
1030 2001-12-27  Akim Demaille  <akim@epita.fr>
1031
1032         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
1033         duplication.
1034
1035 2001-12-27  Akim Demaille  <akim@epita.fr>
1036
1037         * src/reader.c (packgram): Catch nitems overflows.
1038
1039 2001-12-27  Akim Demaille  <akim@epita.fr>
1040
1041         * src/files.c, src/files.h (guard_obstack): Remove.
1042         * src/output.c (output): Adjust.
1043         * src/reader.c (parse_braces): New, factoring...
1044         (copy_action, copy_guard): these two which are renamed as...
1045         (parse_action, parse_guard): these.
1046         As a voluntary consequence, using braces around guards is now
1047         mandatory.
1048
1049 2001-12-27  Akim Demaille  <akim@epita.fr>
1050
1051         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
1052         * src/reader.c (symbol_list): `guard' and `guard_line' are new
1053         members.
1054         (symbol_list_new): Adjust.
1055         (copy_action): action_line is the first line, not the last.
1056         (copy_guard): Just as for actions, store the `action' only, not
1057         the switch/case/break flesh.
1058         Don't parse the user action that might follow the guard, let...
1059         (readgram): do it, i.e., now, there can be an action after a
1060         guard.
1061         In other words the guard is just explicitly optional.
1062         (packgram): Adjust.
1063         * src/output.c (guards_output): New.
1064         (output_parser): Call it when needed.
1065         (output): Also free the guard and attrs obstacks.
1066         * src/files.c, src/files.h (obstack_save): Remove.
1067         (output_files): Remove.
1068         As a result, if one needs the former `.act' file, using an
1069         appropriate skeleton which requires actions and guards is now
1070         required.
1071         * src/main.c (main): Adjust.
1072         * tests/semantic.at: New.
1073         * tests/regression.at: Use `input.y' as input file name.
1074         Avoid 8+3 problems by requiring input.c when the test needs the
1075         parser.
1076
1077 2001-12-27  Akim Demaille  <akim@epita.fr>
1078
1079         * src/reader.c (symbol_list_new): Be sure to initialize all the
1080         fields.
1081
1082 2001-12-27  Akim Demaille  <akim@epita.fr>
1083
1084         All the hacks using a final pseudo state are now useless.
1085
1086         * src/LR0.c (set_state_table): state_table holds exactly nstates.
1087         * src/lalr.c (nLA): New.
1088         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
1089         instead of lookaheadsp from the pseudo state (nstate + 1).
1090
1091 2001-12-27  Akim Demaille  <akim@epita.fr>
1092
1093         * src/output.c (action_row, token_actions): Use a state_t instead
1094         of a integer, and nlookaheads instead of the following state's
1095         lookaheadsp.
1096
1097 2001-12-27  Akim Demaille  <akim@epita.fr>

1101         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
1102         (conflicts_print, print_reductions): Use a state_t instead of an
1103         integer when referring to a state.
1104         As much as possible, depend upon nlookaheads, instead of the
1105         `lookaheadsp' member of the following state (since lookaheads of
1106         successive states are successive, the difference between state n + 1
1107         and n served as the number of lookaheads for state n).

1118         ANSIfy.
1119         Remove `register' indications.
1120         Add plenty of `static'.

1123
1124         * src/output.c (prepare): Drop the muscle `ntbase' which
1125         duplicates ntokens.
1126         * src/bison.simple: Formatting/comment changes.
1127         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
1128         is an undocumented synonym.
1129
1130 2001-12-22  Akim Demaille  <akim@epita.fr>
1131
1132         * src/output.c (output_table_data): Change the prototype to use
1133         `int' for array ranges: some invocations do pass an int, not a
1134         short.
1135         Reported by Wayne Green.

1139         Some actions of web2c.y are improperly triggered.
1140         Reported by Mike Castle.
1141
1142         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
1143         * tests/regression.at (Web2c): Rename as...

1159         Reported by Nelson Beebee.
1160
1161         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with

1164 2001-12-17  Marc Autret  <autret_m@epita.fr>
1165
1166         * src/bison.simple: Don't hard code the skeleton line and filename.
1167         * src/output.c (output_parser): Rename 'line' as 'output_line'.
1168         New line counter 'skeleton_line' (skeleton-line muscle).
1169
1170 2001-12-17  Paul Eggert  <eggert@twinsun.com>
1171
1172         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
1173         YYDEBUG must be defined to a nonzero value.
1174
1175         * src/bison.simple (yytname): Do not assume that the user defines

1177
1178 2001-12-17  Akim Demaille  <akim@epita.fr>
1179

1205
1206         * src/output.c (output_obstack): Be static and rename as...

1208         output_obstack.
1209         * src/reader.h (muscle_obstack): Move to...
1210         * src/output.h: here, since it's defined in output.c.

1233         there is one less line per action.
1234
1235 2001-12-16  Marc Autret  <autret_m@epita.fr>
1236
1237         * src/bison.simple: Remove a useless #line directive.
1238         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1239         * src/output.c (get_lines_number): New.
1240         (output_parser): Adjust, now takes care about the lines of a
1241         output muscles.
1242         Fix line numbering.
1243         (actions_output): Computes the number of lines taken by actions.
1244         (output_master_parser): Insert new skeleton which is the name of
1245         the output parser file name.
1246
1247 2001-12-15  Marc Autret  <autret_m@epita.fr>
1248
1249         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
1250
1251 2001-12-15  Marc Autret  <autret_m@epita.fr>
1252
1253         * src/output.c (output_gram): Keep track of the hairy one.
1254
1255 2001-12-15  Akim Demaille  <akim@epita.fr>
1256
1257         Make `make distcheck' work.
1258
1259         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1260         system.h which uses libgettext.h.
1261
1262 2001-12-15  Akim Demaille  <akim@epita.fr>
1263
1264         * src/nullable.c (set_nullable): Useless rules must be skipped,
1265         otherwise, since we range over their symbols, we might look at a
1266         nonterminal which no longer ``exists'', i.e., it is not counted in
1267         `nvars', hence we overflow our arrays.
1268
1269 2001-12-15  Akim Demaille  <akim@epita.fr>
1270
1271         The header can also be produced directly, without any obstack!
1272         Yahoo!
1273
1274         * src/files.c, src/files.h (defines_obstack): Remove.
1275         (compute_header_macro): Global.
1276         (defines_obstack_save): Remove.
1277         * src/reader.c (parse_union_decl): No longer output to
1278         defines_obstack: its content can be found in the `stype' muscle
1279         anyway.
1280         (output_token_translations): Merge into...
1281         (symbols_output): this.
1282         Rename as...
1283         (symbols_save): this.
1284         (reader): Adjust.
1285         * src/output.c (header_output): New.

1287
1288 2001-12-15  Akim Demaille  <akim@epita.fr>
1289
1290         * src/reader.c (parse_union_decl): Instead of handling two obstack
1291         simultaneously, use one to define the `stype' muscle, and use the
1292         value of the latter to fill defines_obstack.
1293         (copy_comment): Remove.
1294         (copy_comment2): Work for a single obstack.
1295         Rename as...
1296         (copy_comment): this.
1297
1298 2001-12-15  Akim Demaille  <akim@epita.fr>
1299
1300         * src/lex.c, src/lex.h (xgetc): No longer static.
1301         * src/reader.c (parse_union_decl): Revamp.
1302
1303 2001-12-15  Akim Demaille  <akim@epita.fr>
1304
1305         Still making progress in separating Bison into (i) input, (ii)
1306         process, (iii) output: now we can directly output the parser file
1307         without using table_obstack at all.
1308
1309         * src/files.c, src/files.h (table_obstack): Bye bye.
1310         (parser_file_name): New.
1311         * src/files.c (compute_output_file_names): Compute it.
1312         * src/output.c (actions_output, output_parser)
1313         (output_master_parser): To a file instead of an obstack.
1314
1315 2001-12-15  Akim Demaille  <akim@epita.fr>
1316
1317         Attach actions to rules, instead of pre-outputting them to
1318         actions_obstack.
1319
1320         * src/gram.h (rule_t): action and action_line are new members.
1321         * src/reader.c (symbol_list): Likewise.
1322         (copy_action): Save the actions within the rule.
1323         (packgram): Save them in rule_table.
1324         * src/output.c (actions_output): New.
1325         (output_parser): Use it on `%%actions'.
1326         (output_rule_data): Don't free rule_table.
1327         (output): Do it.
1328         (prepare): Don't save the `action' muscle.
1329         * src/bison.simple: s/%%action/%%actions/.
1330
1331 2001-12-15  Akim Demaille  <akim@epita.fr>
1332
1333         * src/reader.c (copy_action): When --yacc, don't append a `;'
1334         to the user action: let it fail if lacking.
1335         Suggested by Arnold Robbins and Tom Tromey.
1336
1337 2001-12-14  Akim Demaille  <akim@epita.fr>
1338
1339         * src/lex.c (literalchar): Simply return the char you decoded, non
1340         longer mess around with obstacks and int pointers.
1341         Adjust all callers.
1342
1343 2001-12-14  Akim Demaille  <akim@epita.fr>
1344
1345         * src/lex.c (literalchar): Don't escape the special characters,
1346         just decode them, and keep them as char (before, eol was output as
1347         the 2 char string `\n' etc.).
1348         * src/output.c (output_rule_data): Use quotearg to output the
1349         token strings.
1350
1351 2001-12-13  Paul Eggert  <eggert@twinsun.com>
1352
1353         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1354         Do not infringe on the global user namespace when using C++.
1355         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1356         All uses of `fprintf' and `stderr' changed.
1357
1358         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1359
1360 2001-12-13  Akim Demaille  <akim@epita.fr>
1361
1362         The computation of nullable is broken: it doesn't handle empty
1363         RHS's properly.
1364
1365         * tests/torture.at (GNU AWK Grammar): New.
1366         * tests/sets.at (Nullable): New.
1367         * src/nullable.c (set_nullable): Instead of blindly looping over
1368         `ritems', loop over the rules, and then over their rhs's.
1369
1370         Work around Autotest bugs.
1371
1372         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1373         frame, because Autotest understand lines starting with a `+' as
1374         traces from the shell.  Then, they are not processed properly.
1375         Admittedly an Autotest bug, but we don't have time to wait for
1376         Autotest to catch up.
1377         * tests/regression.at (Broken Closure): Adjust to the new table
1378         frames.
1379         Move to...
1380         * tests/sets.at: here.
1381
1382 2001-12-13  Akim Demaille  <akim@epita.fr>
1383
1384         * src/closure.c (closure): Use nrules instead of playing tricks
1385         with BITS_PER_WORD.
1386
1387 2001-12-13  Akim Demaille  <akim@epita.fr>
1388
1389         * src/print.c (print_actions): Output the handling of `$' as the
1390         traces do: shifting the token EOF.  Before EOF was treated as a
1391         nonterminal.
1392         * tests/regression.at: Adjust some tests.
1393         * src/print_graph.c (print_core): Complete the set of items via
1394         closure.  The next-to-final and final states are still unsatisfying,
1395         but that's to be addressed elsewhere.
1396         No longer output the rule numbers, but do output the state number.
1397         A single loop for the shifts + gotos is enough, but picked a
1398         distinct color for each.
1399         (print_graph): Initialize and finalize closure.
1400
1401 2001-12-13  Akim Demaille  <akim@epita.fr>
1402
1403         * src/reader.c (readgram): Remove dead code, an strip useless
1404         braces.
1405         (get_type): Remove, unused.
1406
1407 2001-12-12  Akim Demaille  <akim@epita.fr>
1408
1409         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1410         on that of lib/error.c.
1411
1412 2001-12-12  Akim Demaille  <akim@epita.fr>
1413
1414         Some hosts don't like `/' in includes.
1415
1416         * src/system.h: Include libgettext.h without qualifying the path.
1417         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1418         $(top_srcdir).
1419
1420 2001-12-11  Marc Autret  <autret_m@epita.fr>
1421
1422         * src/output.c (output_parser): Remove useless muscle.
1423
1424 2001-12-11  Marc Autret  <autret_m@epita.fr>
1425
1426         * src/bison.simple: Remove #line just before %%epilogue. It
1427         is now handled in ...
1428         * src/reader.c (read_additionnal_code): Add the output of a
1429         #line for the epilogue.
1430
1431 2001-12-10  Marc Autret  <autret_m@epita.fr>
1432
1433         * src/reader.c (copy_definition): Re-use CPP-outed code which
1434         replace precedent remove.
1435         * src/bison.simple: Remove #line before %%prologue because
1436         %%input-line is wrong at this time.
1437
1438 2001-12-10  Marc Autret  <autret_m@epita.fr>
1439
1440         * src/reader.c (symbols_output): Clean up.
1441         * src/output.c (output_gram, output): Clean up.
1442
1443 2001-12-10  Akim Demaille  <akim@epita.fr>
1444
1445         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
1446         * src/LR0.c (set_state_table): here.
1447         * src/lalr.c (lalr): Call it.
1448
1449 2001-12-10  Akim Demaille  <akim@epita.fr>
1450
1451         * src/state.h (shifts): Remove the `number' member: shifts are
1452         attached to state, hence no longer need to be labelled with a
1453         state number.
1454
1455 2001-12-10  Akim Demaille  <akim@epita.fr>
1456
1457         Now that states have a complete set of members, the linked list of
1458         shifts is useless: just fill directly the state's shifts member.
1459
1460         * src/state.h (shifts): Remove the `next' member.
1461         * src/LR0.c (first_state, last_state): Remove.
1462         Adjust the callers.
1463         (augment_automaton): Don't look for the shifts that must be added
1464         a shift on EOF: it is those of the state we looked for!  But now,
1465         since shifts are attached, it is no longer needed to looking
1466         merely by its id: its number.
1467
1468 2001-12-10  Akim Demaille  <akim@epita.fr>
1469
1470         * src/LR0.c (augment_automaton): Better variable locality.
1471         Remove an impossible branch: if there is a state corresponding to
1472         the start symbol being shifted, then there is shift for the start
1473         symbol from the initial state.
1474
1475 2001-12-10  Akim Demaille  <akim@epita.fr>
1476
1477         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1478         only when appropriate: when insert_start_shifting_state' is not
1479         invoked.
1480         * tests/regression.at (Rule Line Numbers): Adjust.
1481
1482 2001-12-10  Akim Demaille  <akim@epita.fr>
1483
1484         * src/LR0.c (augment_automaton): Now that all states have shifts,
1485         merge the two cases addition shifts to the initial state.
1486
1487 2001-12-10  Akim Demaille  <akim@epita.fr>
1488
1489         * src/lalr.c (set_state_table): Move to...
1490         * src/LR0.c: here.
1491         * src/lalr.c (lalr): Don't call it...
1492         * src/LR0.c (generate_states): do it.
1493         * src/LR0.h (first_state): Remove, only the table is used.
1494
1495 2001-12-10  Akim Demaille  <akim@epita.fr>
1496
1497         * src/LR0.h (first_shift, first_reduction): Remove.
1498         * src/lalr.c: Don't use first_shift: find shifts through the
1499         states.
1500
1501 2001-12-10  Akim Demaille  <akim@epita.fr>
1502
1503         * src/LR0.c: Attach shifts to states as soon as they are
1504         computed.
1505         * src/lalr.c (set_state_table): Instead of assigning shifts to
1506         state, just assert that the mapping was properly done.
1507
1508 2001-12-10  Akim Demaille  <akim@epita.fr>
1509
1510         * src/LR0.c (insert_start_shift): Rename as...
1511         (insert_start_shifting_state): this.
1512         (insert_eof_shifting_state, insert_accepting_state): New.
1513         (augment_automaton): Adjust.
1514         Better locality of the variables.
1515         When looking if the start_symbol is shifted from the initial
1516         state, using `while (... symbol != start_symbol ...)' sounds
1517         better than `while (... symbol < start_symbol ...)': If fail
1518         to see how the order between symbols could be relevant!
1519
1520 2001-12-10  Akim Demaille  <akim@epita.fr>
1521
1522         * src/getargs.h: Don't declare `spec_name_prefix' and
1523         `spec_file_prefix', declared by src/files.h.
1524         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1525         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1526         * src/output.c (prepare): Adjust.
1527         * src/reader.c (symbols_output): Likewise.
1528         * src/vmsgetargs.c: Vaguely adjust, but who cares?
1529
1530 2001-12-10  Akim Demaille  <akim@epita.fr>
1531
1532         * src/muscle_tab.c (muscle_init): NULL is a better default than
1533         `"0"'.
1534
1535 2001-12-10  Akim Demaille  <akim@epita.fr>
1536
1537         * src/reader.c (reader): Calling symbols_output once is enough.
1538
1539 2001-12-10  Akim Demaille  <akim@epita.fr>
1540
1541         Now that states have a complete set of members, the linked list of
1542         reductions is useless: just fill directly the state's reductions
1543         member.
1544
1545         * src/state.h (struct reductions): Remove member `number' and
1546         `next'.
1547         * src/LR0.c (first_reduction, last_reduction): Remove.
1548         (save_reductions): Don't link the new reductions, store them in
1549         this_state.
1550         * src/lalr.c (set_state_table): No need to attach reductions to
1551         states, it's already done.
1552         * src/output.c (output_actions): No longer free the shifts, then
1553         the reductions, then the states: free all the states and their
1554         members.
1555
1556 2001-12-10  Akim Demaille  <akim@epita.fr>
1557
1558         * src/options.c (OPTN, DRTV, BOTH): New.
1559         (option_table): Use them.
1560
1561         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1562         the job of system.h.
1563         * src/options.c: Don't include stdio.h and xalloc.h for the same
1564         reasons.
1565
1566 2001-12-10  Akim Demaille  <akim@epita.fr>
1567
1568         * src/output.c (output, prepare): Make sure the values of the
1569         muscles `action' and `prologue' are 0-terminated.
1570
1571 2001-12-10  Akim Demaille  <akim@epita.fr>
1572
1573         Clean up GCC warnings.
1574
1575         * src/reader.c (copy_action): `buf' is not used.
1576         (parse_skel_decl): Be static.
1577         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1578         * src/options.h (create_long_option_table): Have a real prototype.
1579         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1580         (hash_delete_at): Return const void *.
1581         Adjust casts to preserve the const.
1582
1583 2001-12-10  Akim Demaille  <akim@epita.fr>
1584
1585         * configure.in: Require 2.52g.
1586         M4 is not needed, but AUTOM4TE is.
1587         * m4/m4.m4: Remove.
1588         * tests/Makefile.am: Adjust.
1589
1590 2001-12-10  Akim Demaille  <akim@epita.fr>
1591
1592         One structure for states is enough, even though theoretically
1593         there are LR(0) states and LALR(1) states.
1594
1595         * src/lalr.h (state_t): Remove.
1596         (state_table): Be state_t **, not state_t *.
1597         * src/state.h (core, CORE_ALLOC): Rename as...
1598         (state_t, STATE_ALLOC): this.
1599         Add the LALR(1) members: shifts, reductions, errs.
1600         * src/LR0.c (state_table): Rename as...
1601         (state_hash): this, to avoid name clashes with the global
1602         `state_table'.
1603         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1604         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
1605
1606 2001-12-10  Akim Demaille  <akim@epita.fr>
1607
1608         Bison dumps core on bash.y.
1609         Reported by Pascal Bart.
1610
1611         * src/warshall.c (bitmatrix_print): New.
1612         (TC): Use it.
1613         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1614         j must be the outer loop.
1615         * tests/regression.at (Broken Closure): New.
1616
1617 2001-12-05  Akim Demaille  <akim@epita.fr>
1618
1619         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1620         its argument.
1621         Reported by Peter Hámorský.
1622
1623 2001-12-05  Akim Demaille  <akim@epita.fr>
1624
1625         * src/conflicts.c (err_table): Remove.
1626         (resolve_sr_conflict): Adjust.
1627         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1628         Rename as...
1629         (state_t.reductions, state_t.shifts): this.
1630
1631 2001-12-05  Akim Demaille  <akim@epita.fr>
1632
1633         * src/reduce.c (reduce_grammar_tables): No longer disable the
1634         removal of useless rules via CPP but via `if (0)', so that the
1635         compiler still check the code is valid.
1636         For instance, it should have noticed `rline' no longer exists: use
1637         the `line' member of rule_t.
1638         * src/gram.c (dummy, rline): Remove, unused.
1639
1640 2001-12-05  Akim Demaille  <akim@epita.fr>
1641
1642         * src/output.c (pack_vector): Use assert, not berror.
1643         * src/main.c (berror): Remove, unused.
1644
1645 2001-12-05  Akim Demaille  <akim@epita.fr>
1646
1647         New experimental feature: if --verbose --trace output all the
1648         items of a state, not only its kernel.
1649
1650         * src/print.c (print_core): If `trace_flag', then invoke closure
1651         before outputting the items of the state (print_core is no longer
1652         a correct name them).
1653         (print_results): Invoke new_closure/free_closure if needed.
1654
1655 2001-12-05  Akim Demaille  <akim@epita.fr>
1656
1657         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1658         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1659         (nitemset): for consistency with the rest of the project.
1660
1661 2001-12-05  Akim Demaille  <akim@epita.fr>
1662
1663         * src/closure.c (print_closure): Improve.
1664         (closure): Use it for printing input and output.
1665
1666 2001-12-05  Akim Demaille  <akim@epita.fr>
1667
1668         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1669         indexed by nonterminals.
1670
1671 2001-12-05  Akim Demaille  <akim@epita.fr>
1672
1673         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1674         what it was!).
1675         * src/warshall.h: Remove accidental duplication of the content.
1676
1677 2001-12-05  Akim Demaille  <akim@epita.fr>
1678
1679         * src/closure.c (set_fderives): De-obfuscate.

1688
1689 2001-12-05  Akim Demaille  <akim@epita.fr>
1690
1691         * src/output.c (action_row): De-obfuscate
1692         using the good o' techniques: arrays not pointers, variable
1693         locality, BITISSET, RESETBIT etc.
1694
1695 2001-12-05  Akim Demaille  <akim@epita.fr>
1696
1697         Pessimize the code to simplify it: from now on, all the states
1698         have a valid SHIFTS, which NSHIFTS is possibly 0.
1699
1700         * src/LR0.c (shifts_new): Be global and move to..
1701         * src/state.c, src/state.h: here.
1702         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1703         * src/print_graph: Adjust.
1704
1705 2001-12-05  Akim Demaille  <akim@epita.fr>
1706
1707         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1708         * src/conflicts.c: Use it.
1709         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1710         incorrectly ``simplified''.
1711
1712 2001-12-05  Akim Demaille  <akim@epita.fr>
1713
1714         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1715         using the good o' techniques: arrays not pointers, variable
1716         locality, BITISSET, RESETBIT etc.
1717
1718 2001-12-05  Akim Demaille  <akim@epita.fr>
1719
1720         * src/state.h (SHIFT_SYMBOL): New.

1722
1723 2001-12-05  Akim Demaille  <akim@epita.fr>
1724
1725         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1726         (print_reductions): De-obfuscate using the good o' techniques:
1727         arrays not pointers, variable locality, BITISSET.
1728
1729 2001-12-05  Akim Demaille  <akim@epita.fr>
1730
1731         * src/conflicts.c (print_reductions): Arrays, not pointers.

1754
1755 2001-12-05  Akim Demaille  <akim@epita.fr>
1756
1757         * src/LR0.c (augment_automaton): Formatting changes.
1758         Better variable locality.
1759
1760 2001-12-05  Akim Demaille  <akim@epita.fr>
1761
1762         * src/lalr.c (matrix_print): New.
1763         (transpose): Use it.
1764         Use arrays instead of pointers.
1765
1766 2001-12-05  Akim Demaille  <akim@epita.fr>
1767
1768         * src/lalr.c (maxrhs): Move to...
1769         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1770         * src/lalr.c (build_relations): Adjust.
1771
1772 2001-12-05  Akim Demaille  <akim@epita.fr>
1773
1774         * src/lalr.c (transpose): Free the memory allocated to the
1775         argument, as it is replaced by the results by the unique caller.
1776         (build_relations): Merely invoke transpose: it handles the memory
1777         deallocation.
1778         Improve variable locality.
1779         Avoid variables used as mere abbreviations.
1780         (compute_lookaheads): Use arrays instead of pointers.
1781
1782 2001-12-05  Akim Demaille  <akim@epita.fr>
1783
1784         * src/lalr.c (initialize_F): Improve variable locality.

1786
1787 2001-12-05  Akim Demaille  <akim@epita.fr>
1788
1789         * src/derives.c (print_derives): Display the ruleno.
1790         * src/lalr.c (initialize_F, transpose): Better variable locality
1791         to improve readability.
1792         Avoid variables used as mere abbreviations.
1793
1794 2001-12-05  Akim Demaille  <akim@epita.fr>
1795
1796         * src/lalr.c (traverse): Use arrays instead of pointers.
1797
1798 2001-12-05  Akim Demaille  <akim@epita.fr>
1799
1800         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1801         the handling of squeue.
1802         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1803
1804 2001-12-05  Akim Demaille  <akim@epita.fr>
1805
1806         Because useless nonterminals are now kept alive (instead of being
1807         `destroyed'), we now sometimes examine them, and store information
1808         related to them.  Hence we need to know their number, and adjust
1809         memory allocations.
1810
1811         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1812         static.
1813         * src/LR0.c (allocate_itemsets): The memory allocated to
1814         `symbol_count' was used for two different purpose: once to count
1815         the number of occurrences of each symbol, and later reassigned to
1816         `shift_symbol', containing the symbol that can be shifted from a
1817         given state.
1818         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1819         only, and...
1820         (new_itemsets): Allocate `shift_symbol' here.
1821         (allocate_itemsets): symbol_count includes useless nonterminals.
1822         Make room for them.
1823         (free_storage): Use `free', not `XFREE', for pointers that cannot
1824         be null.

1827
1828         * src/nullable.c (set_nullable): Deobfuscate the handling of
1829         ritem.
1830         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1831
1832 2001-12-05  Akim Demaille  <akim@epita.fr>
1833
1834         * src/gram.c, src/gram.h (ritem_print): New.
1835         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1836         (This useless function was defined only to work around VMS linkers
1837         that can't handle compilation units with variables only).
1838         * src/reduce.c (dump_grammar): Use it to trace the construction of
1839         ritem.
1840
1841 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1842
1843         * src/bison.simple (union yyalloc): Change member names
1844         to be the same as the stack names.
1845         (yyparse): yyptr is now union yyalloc *, not char *.
1846         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1847         and may generate better code on some machines.
1848         (yystpcpy): Use prototype if __STDC__ is defined, not just
1849         if __cplusplus is defined.
1850
1851 2001-11-30  Akim Demaille  <akim@epita.fr>
1852
1853         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1854         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1855         Gettext doesn't compile cleanly, and dies with -Werror.
1856         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1857         Include WARNING_CFLAGS here.
1858         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1859         before being defined.
1860

1866         (SIZE_MAX, UINT_MAX): New macros.
1867         (quotearg_n_options): Abort if N is negative.
1868         Avoid overflow check on hosts where size_t is 64 bits and int
1869         is 32 bits, as overflow is impossible there.
1870         Fix off-by-one typo that caused unnecessary reallocation.
1871
1872 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1873
1874         Name space cleanup in generated parser.
1875
1876         * doc/bison.texinfo (Bison Parser): Discuss system headers
1877         and their effect on the user name space.
1878
1879         * src/bison.simple:
1880         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1881         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1882         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1883
1884         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1885         on user names when possible.
1886
1887         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1888         Simplify test for whather <alloca.h> exists.
1889
1890         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.

1901
1902         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1903         All uses changed.
1904
1905         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1906         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1907         and YYSTACK_FREE instead of malloc and free.
1908
1909 2001-11-30  Akim Demaille  <akim@epita.fr>

1920
1921         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1922         if body instead of `;' to pacify GCC's warnings.
1923
1924 2001-11-30  Akim Demaille  <akim@epita.fr>
1925
1926         Instead of mapping the LHS of unused rules to -1, keep the LHS
1927         valid, but flag the rules as invalid.
1928
1929         * src/gram.h (rule_t): `useful' is a new member.

1944
1945         * src/reduce.c (nonterminals_reduce): Instead of throwing away
1946         useless nonterminals, move them at the end of the symbol arrays.

1948         * tests/reduce.at (Useless Nonterminals): Adjust.
1949

1953         (nonterminals_reduce): New, extracted from...
1954         (reduce_grammar_tables): here.
1955         (reduce_grammar): Call nonterminals_reduce.

1962         New macros.
1963         (union yyalloc): New type.
1964         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1965         an arbitrary restriction on hosts where size_t is wider than int.
1966
1967         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1968         a parser stack overflow.  Allocate just one block of memory for all
1969         three stacks, instead of allocating three blocks; this typically is
1970         faster and reduces fragmentation.
1971
1972         Do not limit the number of items in the stack to a value that fits
1973         in 'int', as this is an arbitrary limit on hosts with 64-bit
1974         size_t and 32-bit int.
1975
1976 2001-11-29  Marc Autret  <autret_m@epita.fr>

2029 2001-11-28  Akim Demaille  <akim@epita.fr>
2030
2031         * src/closure.c (closure): Instead of looping over word in array
2032         then bits in words, loop over bits in array.
2033
2034 2001-11-28  Akim Demaille  <akim@epita.fr>
2035
2036         * src/closure.c (closure): No longer optimize the special case

2175         Attaching lineno to buckets is stupid, since only one copy of each

2528         * src/bison.simple: Define type yystype instead of YYSTYPE, and
2529         define CPP macro, which substitute YYSTYPE by yystype.

2531         with yyltype/YYLTYPE.  This allows inclusion of the generated

2533         multiple equivalent #defines.

3353
3354         * src/bison.simple (yyparse): Don't take the address of an

3364         completely wrong.

3403         bound to true.
3404         (read_declarations): Add case for macro definition.
3405         (copy_identifier): New.
3406         (parse_macro_decl): Read macro identifiers using copy_identifier
3407         rather than lex.

3413         (output_parser): Fix bug on '%%line' directives.

3426         table with a macro. No output to the table obstack.
3427         (output_gram): Same for 'rhs' and 'prhs'.

3439
3440         * src/output.c (output_parser): Replace most of the skeleton copy code
3441         with something new. Skeletons are now processed character by character
3442         rather than line by line, and Bison looks for '%%' macros. This is the
3443         first step in making Bison's output process (a lot) more flexible.
3444         (output_parser): Use the macro table.

3772
3773         * src/reader.c (gensym): `gensym_count' is your own.
3774         Use a static buf to create the symbol name, as token_buffer is no
3775         longer a buffer.
3776

3778
3779         * src/conflicts.c (conflict_report): Be sure not to append to res

3786         New, from fileutils 4.0.37.
3787         * configure.in: Require Autoconf 2.49c.  I took some time before
3788         making this decision.  This is the only way out for portability
3789         issues in Bison, it would mean way too much duplicate effort to
3790         import in Bison features implemented in 2.49c since 2.13.
3791         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

3809
3810         * src/lex.h: Rename all the tokens:

3812         s/\bIDENTIFIER\b/tok_identifier/g;
3813         etc.
3814         Let them be enums, not #define, to ease debugging.
3815         Adjust all the code.
3816
3817 2001-01-18  Akim Demaille  <akim@epita.fr>
3818
3819         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

3821
3822 2001-01-18  Akim Demaille  <akim@epita.fr>
3823
3824         Since we now use obstacks, more % directives can be enabled.
3825
3826         * src/lex.c (percent_table): Also accept `%yacc',
3827         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3828         `%debug'.
3829         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3830         instead of returning a token.
3831         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3832         * src/reader.c (read_declarations): Adjust.
3833         * src/files.c (open_files): Don't call `compute_base_names', don't
3834         compute `attrsfile' since they depend upon data which might be
3835         *in* the input file now.
3836         (output_files): Do it here.
3837         * src/output.c (output_headers): Document the fact that this patch
3838         introduces a guaranteed SEGV for semantic parsers.
3839         * doc/bison.texinfo: Document them.

3860
3861         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
3862         (copy_dollar): Now that everything uses obstacks, get rid of the
3863         FILE * parameters.
3864
3865 2000-12-20  Akim Demaille  <akim@epita.fr>
3866
3867         * src/files.c (open_files): Actually the `.output' file is based
3868         on the short_base_name, not base_name.
3869         * tests/suite.at (Checking output file names): Adjust.
3870
3871 2000-12-20  Akim Demaille  <akim@epita.fr>
3872
3873         * src/bison.s1: Remove, we now use directly...

3897         (stringappend): Be just like strcat but allocate.
3898         (base_names): Eve out from open_files.
3899         Try to simplify the rather hairy computation of base_name and
3900         short_base_name.
3901         (open_files): Use it.
3902         * tests/suite.at (Checking output file names): New test.

3912
3913 2000-12-19  Akim Demaille  <akim@epita.fr>

3919
3920 2000-12-19  Akim Demaille  <akim@epita.fr>
3921
3922         Let the handling of the skeleton files be local to the procedures
3923         that use it.

3941

3973
3974         * lib/obstack.h: Formatting changes.
3975         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3976         prevents type checking.
3977         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3978         cast the value to (void *): assigning a `foo *' to a `void *'
3979         variable is valid.

4018

4061         * src/main.c (main): Don't use `atexit' to register `done', since
4062         it no longer has to remove tmp files, just call `output_files'
4063         when there are no errors.
4064
4065 2000-11-02  Akim Demaille  <akim@epita.fr>

4165
4166 2000-10-04  Akim Demaille  <akim@epita.fr>

4169         `bison -v' segfaults.
4170         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
4171
4172         * tests/regression.m4: New file.

4184
4185         * bison.s1 (yyparse): Assign the default value
4186         unconditionally, to avoid a GCC warning and make the parser a
4187         tad smaller.
4188
4189 2000-10-02  Akim Demaille  <akim@epita.fr>
4190

4195
4196         * src/derives.c, src/print.c, src/reduce.c: To ease the

4198
4199 2000-10-02  Akim Demaille  <akim@epita.fr>
4200
4201         The location tracking mechanism is precious for parse error
4202         messages.  Nevertheless, it is enabled only when `@n' is used in
4203         the grammar, which is a different issue (you can use it in error
4204         message, but not in the grammar per se).  Therefore, there should
4205         be another means to enable it.
4206
4207         * src/getargs.c (getargs): Support `--locations'.
4208         (usage): Report it.
4209         * src/getargs.h (locationsflag): Export it.
4210         * src/lex.c (percent_table): Support `%locations'.
4211         * src/reader.c (yylsp_needed): Remove this variable, now replaced
4212         with `locationsflag'.
4213         * doc/bison.texinfo: Document `--locations' and `%locations'.
4214         Sort the options.
4215         * tests/calc.m4: Test it.
4216
4217         For regularity of the names, replace each
4218         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4219         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4220         In addition replace each `flag' with `_flag'.
4221
4222 2000-10-02  Akim Demaille  <akim@epita.fr>
4223
4224         Also test parse error messages, including with YYERROR_VERBOSE.
4225
4226         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4227         associative).
4228         Use it to check the computations.
4229         Use it to check `nonassoc' is honored.
4230         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4231         `--yyerror-verbose'.
4232         (_AT_CHECK_CALC): Adjust to this option.
4233         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4234
4235 2000-10-02  Akim Demaille  <akim@epita.fr>
4236
4237         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
4238         the latter demonstrates a flaw in the handling of non debugging
4239         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4240         was used in order to simplify:
4241
4242         #if YYDEBUG
4243         if (yydebug)
4244         {
4245         ...
4246         }
4247         #endif
4248
4249         into
4250
4251         if (yydebug)
4252         {
4253         ...
4254         }
4255
4256         unfortunately this leads to a CPP conflict when
4257         `--name-prefix=foo' is used since it produces `#define yydebug
4258         foodebug'.
4259
4260         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4261         (YYDPRINTF): New macro.
4262         Spread its use.
4263         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4264         the bison options.
4265         Also test `--verbose', `--defines' and `--name-prefix'.
4266
4267 2000-10-02  Akim Demaille  <akim@epita.fr>
4268
4269         Improve the readability of the produced parsers.
4270
4271         * src/bison.s1: Formatting changes.
4272         Improve the comment related to the `$' mark.
4273         (yydefault): Don't fall through to `yyresume': `goto' there.
4274         * src/output.c (output_parser): When the `$' is met, skip the end
4275         of its line.
4276         New variable, `number_of_dollar_signs', to check there's exactly
4277         one `$' in the parser skeleton.
4278
4279 2000-10-02  Akim Demaille  <akim@epita.fr>
4280
4281         * lib/xstrdup.c: New file, from the fileutils.
4282         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4283         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4284         instead of strlen + xmalloc + strcpy.
4285         * src/symtab.c (copys): Remove, use xstrdup instead.
4286
4287 2000-10-02  Akim Demaille  <akim@epita.fr>
4288
4289         * src/gram.h (associativity): New enum type which replaces the
4290         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4291         `right_assoc', `left_assoc' and `non_assoc'.
4292         Adjust all dependencies.
4293         * src/reader.c: Formatting changes.
4294         (LTYPESTR): Don't define it, use it as a literal in
4295         `reader_output_yylsp'.
4296         * src/symtab.h (symbol_class): New enum type which replaces the
4297         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4298         `sunknown', `stoken and `snterm'.
4299

4301
4302         * src/getargs.c (fixed_outfiles): Rename as...
4303         (yaccflag): for consistency and accuracy.

4308         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4309         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4310         difficult and introduced a lot of core dump.  It turns out that
4311         Bison used an implementation of `xmalloc' based on `calloc', and
4312         at various places it does depend upon the initialization to 0.  I
4313         have not tried to isolate the pertinent places, and all the former
4314         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4315         someone should address this issue.
4316

4417
4418         `user_toknums' is output as a `short[]' in `output.c', while it is
4419         defined as a `int[]' in `reader.c'.  For consistency with the
4420         other output tables, `user_toknums' is now defined as a table of

4465         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

4467         definitions in config.h.

4673         (copy_action): Use it.  Removed now unused `match', `ended',

4684
4685         Change the handling of @s so that they behave exactly like $s.
4686         There is now a pseudo variable @$ (readble and writable), location
4687         of the lhs of the rule (by default ranging from the location of
4688         the first symbol of the rhs, to the location of the last symbol,
4689         or, if the rhs is empty, YYLLOC).
4690
4691         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4692         yyval.
4693         (yyparse): When providing a default semantic action, provide a
4694         default location action.
4695         (after the $): No longer change `*YYLSP', just stack YYLOC the
4696         same way you stack YYVAL.
4697         * src/reader.c (read_declarations): Use warns.
4698         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4699         (copy_action, case '@'): Likewise.
4700         Use a standard error message, to save useless work from
4701         translators.
4702
4703 2000-03-17  Akim Demaille  <akim@epita.fr>
4704
4705         * src/bison.s1: Formatting and cosmetics changes.

4722
4723         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4724         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4725         One `#if YYDEBUG' remains, since it uses variables which are
4726         defined only if `YYDEBUG != 0'.
4727
4728 2000-03-16  Akim Demaille  <akim@epita.fr>

4752         handled via src/Makefile.am.

4754         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
4755         autoheader.

4760         the proper line number and file name.
4761         (DEFS): Propagate the location of bison library files and of the
4762         locale files.
4763         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4764         builddir.
4765         * acinclude.m4: Remove, replaced by the directory m4.
4766         * m4/Makefile.am (EXTRA_DIST): New variable.

5443         (safegetc): New function to deal with EOF gracefully.
5444         (literalchar); new function to deal with reading \ escapes.
5445         (lex): Use literalchar.
5446         (lex): Implemented "..." tokens.
5447         (literalchar, lex, parse_percent_token): Made tokenbuffer
5448         always contain the token.  This includes growing the token
5449         buffer while reading an integer.

5451         (parse_percent_token): Added % declarations as another
5452         way to specify the flags -n, -l, and -r.  Also added hooks for
5453         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
5454         major changes to files.c.
5455         (lex) Retain in the incoming stream a character following
5456         an incorrect '/'.
