 222 2002-02-14  Paul Eggert  <eggert@twinsun.com>
 223
 224         Remove the support for C++ namespace cleanliness; it was
 225         causing more problems than it was curing, since it didn't work
 226         properly on some nonstandard C++ compilers.  This can wait
 227         for a proper C++ parser.
 228
 229         * NEWS: Document this.
 230         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention

 246
 247         * src/output.c (output_rule_data): Don't output NULL, it might
 248         not be defined yet.

 268
 269 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 270
 271         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
 272         more consistent when naming methods and variables.  Put preprocessor
 273         directives around tables only needed for debugging.
 274
 275 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>

 295 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
 296
 297         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
 298         not expanded by m4.
 299
 300 2002-02-05  Akim Demaille  <akim@epita.fr>
 301
 302         * data/bison.c++: Adjust to the M4 back end.

 315         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
 316         * src/output.c (actions_output, guards_output)
 317         (token_definitions_output): No longer keeps track of the output
 318         line number, hence remove the second argument.
 319         (guards_output): Check against the guard member of a rule, not the
 320         action member.
 321         Adjust callers.
 322         (output_skeleton): Don't look for the skeleton location, let m4 do
 323         that.
 324         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
 325         file will be used.
 326         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
 327         (prepare): Given that for the time being changesyntax is not
 328         usable in M4, rename the muscles using `-' to `_'.
 329         Define `defines_flag', `output_parser_name' and `output_header_name'.

 334         * data/bison.simple: Adjust to be used by M4(sugar).
 335         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
 336         to date.
 337         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
 338         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
 339         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
 340         shamelessly stolen from CVS Autoconf.

 357
 358 2002-01-29  Paul Eggert  <eggert@twinsun.com>
 359
 360         * src/bison.simple (YYSIZE_T): Do not define merely because
 361         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 362         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 363
 364 2002-01-27  Akim Demaille  <akim@epita.fr>
 365
 366         Fix `%nonassoc and eof'.
 367
 368         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
 369         which were not properly copied!  Replace

 373         !!!
 374         * tests/regression.at (%nonassoc and eof): Adjust to newest
 375         Autotest: `.' is not in the PATH.
 376
 377 2002-01-27  Akim Demaille  <akim@epita.fr>
 378
 379         * tests/sets.at (AT_EXTRACT_SETS): New.

 382
 383 2002-01-26  Akim Demaille  <akim@epita.fr>
 384
 385         * tests/actions.at, tests/calc.at, tests/headers.at,
 386         * tests/torture.at: Adjust to the newest Autotest which no longer
 387         forces `.' in the PATH.
 388
 389 2002-01-25  Akim Demaille  <akim@epita.fr>
 390
 391         * tests/regression.at (%nonassoc and eof): New.

 396         Bison dumps core when trying to complain about broken input files.
 397         Reported by Cris van Pelt.
 398
 399         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
 400         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
 401         into...
 402         (Invalid inputs): Strengthen: exercise parse_percent_token.
 403
 404 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
 405
 406         * src/Makefile.am: Add bison.c++.
 407         * src/bison.c++: New skeleton.
 408
 409 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
 410
 411         * po/it.po: New.
 412
 413 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
 414
 415         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
 416
 417 2002-01-20  Marc Autret  <marc@gnu.org>
 418
 419         * src/files.c (compute_output_file_names): Fix
 420
 421 2002-01-20  Marc Autret  <marc@gnu.org>
 422
 423         * tests/output.at: New test.
 424         * src/files.c (compute_base_names): Don't map extensions when
 425         the YACC flag is set, use defaults.
 426         Reported by Evgeny Stambulchik.
 427
 428 2002-01-20  Marc Autret  <marc@gnu.org>
 429
 430         * src/system.h: Need to define __attribute__ away for non-GCC
 431         compilers as well (i.e. the vendor C compiler).
 432         Suggested by Albert Chin-A-Young.
 433
 434 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
 435
 436         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
 437         canonical definition.
 438         * src/system.h: Use the canonical definition for PARAMS (avoids
 439         a conflict with the macro from lib/hash.h).
 440
 441 2002-01-11  Akim Demaille  <akim@epita.fr>
 442
 443         * configure.in: Use AC_FUNC_STRNLEN.
 444         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
 445
 446 2002-01-09  Akim Demaille  <akim@epita.fr>
 447
 448         * src/files.c, src/files.h (output_infix): New.
 449         (tab_extension): Remove.
 450         (compute_base_names): Compute the former, drop the latter.
 451         * src/output.c (prepare): Insert the muscles `output-infix', and
 452         `output-suffix'.
 453         * src/parse-skel.y (string, string.1): New.
 454         (section.header): Use it.
 455         (section.yacc): Remove.
 456         (prefix): Remove too.
 457         * src/scan-skel.l: Adjust.
 458         * src/bison.simple, src/bison.hairy: Adjust.
 459
 460 2002-01-09  Akim Demaille  <akim@epita.fr>
 461
 462         * configure.in (WERROR_CFLAGS): Compute it.
 463         * src/Makefile.am (CFLAGS): Pass it.
 464         * tests/atlocal.in (CFLAGS): Idem.
 465         * src/files.c: Fix a few warnings.
 466         (get_extension_index): Remove, unused.
 467
 468 2002-01-08  Akim Demaille  <akim@epita.fr>
 469
 470         * src/getargs.c (AS_FILE_NAME): New.
 471         (getargs): Use it to convert DOSish file names.
 472         * src/files.c (base_name): Rename as full_base_name to avoid
 473         clashes with `base_name ()'.
 474         (filename_split): New.
 475         (compute_base_names): N-th rewrite, using filename_split.
 476
 477 2002-01-08  Akim Demaille  <akim@epita.fr>
 478
 479         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
 480         New, stolen from the Fileutils 4.1.
 481         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
 482         * configure.in: Check for the presence of memrchr, and of its
 483         prototype.
 484
 485 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
 486
 487         * lib/hash.h (__P): Added definition for this macro.
 488         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
 489         BUILT_SOURCES, to ensure they are generated first.
 490         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
 491         %error-verbose to allow bootstrapping with bison 1.30x.
 492
 493 2002-01-06  Akim Demaille  <akim@epita.fr>
 494
 495         * src/reader.c (parse_braces): Don't fetch the next char, the
 496         convention is to fetch on entry.
 497         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
 498         'switch' without a following semicolon.
 499         * tests/regression.at (braces parsing): New.
 500
 501 2002-01-06  Akim Demaille  <akim@epita.fr>
 502
 503         Bison is dead wrong in its RR conflict reports.
 504
 505         * tests/torture.at (GNU Cim Grammar): New.
 506         * src/conflicts.c (count_rr_conflicts): Fix.
 507
 508 2002-01-06  Akim Demaille  <akim@epita.fr>
 509
 510         Creating package.m4 from configure.ac causes too many problems.
 511
 512         * tests/Makefile.am (package.m4): Create it by hand,
 513         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
 514
 515 2002-01-06  Akim Demaille  <akim@epita.fr>
 516
 517         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
 518         skeleton.h.
 519
 520 2002-01-04  Paul Eggert  <eggert@twinsun.com>
 521
 522         * doc/bison.texinfo (Debugging):
 523         Remove YYSTDERR; it's no longer defined or used.
 524         Also, s/cstdio.h/cstdio/.
 525
 526 2002-01-03  Akim Demaille  <akim@epita.fr>
 527
 528         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
 529
 530 2002-01-03  Akim Demaille  <akim@epita.fr>
 531
 532         * src/parse-skel.y (process_skeleton): Don't bind the parser's
 533         tracing code to --trace, wait for a better --trace option, with
 534         args.
 535
 536 2002-01-03  Akim Demaille  <akim@epita.fr>
 537
 538         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
 539         The ISO C++ standard is extremely clear about it: stderr is
 540         considered a macro, not a regular symbol (see table 94 `Header
 541         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
 542         Therefore std:: does not apply to it.  It still does with fprintf.
 543         Also, s/cstdio.h/cstdio/.
 544
 545 2002-01-03  Akim Demaille  <akim@epita.fr>
 546
 547         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
 548         for non system headers.
 549
 550 2002-01-02  Akim Demaille  <akim@epita.fr>
 551
 552         Equip the skeleton chain with location tracking, runtime trace,
 553         pure parser and scanner.
 554
 555         * src/parse-skel.y: Request a pure parser, locations, and prefix
 556         renaming.
 557         (%union): Having several members with the same type does not help
 558         type mismatches, simplify.
 559         (YYPRINT, yyprint): New.
 560         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
 561         (skel_error): this.
 562         Handle locations.
 563         * src/scan-skel.l: Adjust to these changes.
 564         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
 565         (LOCATION_PRINT, skel_control_t): New.
 566
 567 2001-12-30  Akim Demaille  <akim@epita.fr>
 568
 569         * src/parse-skel.y: Get rid of the shift/reduce conflict:
 570         replace `gb' with BLANKS.
 571         * src/scan-skel.l: Adjust.
 572
 573 2001-12-30  Akim Demaille  <akim@epita.fr>
 574
 575         * src/system.h: We don't need nor want bcopy.
 576         Throw away MS-DOS crap: we don't need getpid.
 577         * configure.in: We don't need strndup.  It was even causing
 578         problems: because Flex includes the headers *before* us,
 579         _GNU_SOURCE is not defined by config.h, and therefore strndup was
 580         not visible.
 581         * lib/xstrndup.c: New.
 582         * src/scan-skel.l: Use it.
 583         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
 584         * src/parse-skel.y: Use %directives instead of #defines.
 585
 586 2001-12-30  Akim Demaille  <akim@epita.fr>
 587
 588         * src/skeleton.h: New.
 589         * src/output.c (output_parser, output_master_parser): Remove, dead
 590         code.
 591         * src/output.h (get_lines_number, actions_output, guards_output)
 592         (token_definitions_output): Prototype them.
 593         * src/parse-skel.y: Add the license notice.
 594         Include output.h and skeleton.h.
 595         (process_skeleton): Returns void, and takes a single parameter.
 596         * src/scan-skel.l: Add the license notice.
 597         Include skeleton.h.
 598         Don't use %option yylineno: it seems that then Flex imagines
 599         REJECT has been used, and therefore it won't reallocate its
 600         buffers (which makes no other sense to me than a bug).  It results
 601         in warnings for `unused: yy_flex_realloc'.
 602
 603 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
 604
 605         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 606         (MUSCLE_INSERT_PREFIX): ...to there.
 607         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 608         (MUSCLE_INSERT_PREFIX): Move from here...
 609
 610         * src/bison.hairy: Add a section directive.  Put braces around muscle
 611         names.  This parser skeleton is still broken, but Bison should not
 612         choke on a bad muscle 'syntax'.
 613         * src/bison.simple: Add a section directive.  Put braces around muscle
 614         names.
 615
 616         * src/files.h (strsuffix, stringappend): Add declarations.
 617         (tab_extension): Add declaration.
 618         (short_base_name): Add declaration.
 619
 620         * src/files.c (strsuffix, stringappend): No longer static.  These
 621         functions are used in the skeleton parser.
 622         (tab_extension): New.
 623         (compute_base_names): Use the computations done in this function
 624         to guess if the generated parsers should have '.tab' in their
 625         names.
 626         (short_base_name): No longer static.
 627
 628         * src/output.c (output_skeleton): New.
 629         (output): Disable call to output_master_parser, and give a try to
 630         a new skeleton handling system.
 631         (guards_output, actions_output): No longer static.
 632         (token_definitions_output, get_lines_number): No longer static.
 633
 634         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
 635
 636         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
 637         parse-skel.y.
 638
 639         * src/parse-skel.y: New file.
 640         * src/scan-skel.l: New file.
 641
 642 2001-12-29  Akim Demaille  <akim@epita.fr>
 643
 644         %name-prefix is broken.
 645
 646         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
 647         Adjust all dependencies.
 648         * tests/headers.at (export YYLTYPE): Strengthen this test: use
 649         %name-prefix.
 650
 651         Renaming yylval but not yylloc is not consistent.  Now we do.
 652
 653         * src/bison.simple: Prefix yylloc if used.
 654         * doc/bison.texinfo (Decl Summary): Document that.
 655
 656 2001-12-29  Akim Demaille  <akim@epita.fr>
 657
 658         * doc/bison.texinfo: Promote `%long-directive' over
 659         `%long_directive'.
 660         Remove all references to fixed-output-files, yacc is enough.
 661
 662 2001-12-29  Akim Demaille  <akim@epita.fr>
 663
 664         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
 665         user prologue.  These are defaults.
 666         * tests/actions.at (Mid-rule actions): Make sure the user can
 667         define YYDEBUG and YYERROR_VERBOSE.
 668
 669 2001-12-29  Akim Demaille  <akim@epita.fr>
 670
 671         * src/output.c (header_output): Don't forget to export YYLTYPE and
 672         yylloc.
 673         * tests/headers.at (export YYLTYPE): New, make sure it does.
 674         * tests/regression.at (%union and --defines, Invalid CPP headers):
 675         Move to...
 676         * tests/headers.at: here.
 677
 678 2001-12-29  Akim Demaille  <akim@epita.fr>
 679
 680         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
 681
 682 2001-12-29  Akim Demaille  <akim@epita.fr>
 683
 684         * tests/actions.at (Mid-rule actions): Output on a single line
 685         instead of several.
 686
 687 2001-12-29  Akim Demaille  <akim@epita.fr>
 688
 689         * doc/bison.texinfo: Formatting changes.
 690
 691 2001-12-29  Akim Demaille  <akim@epita.fr>
 692
 693         Don't store the token defs in a muscle, just be ready to output it
 694         on command.  Now possible via `symbols'.  Fixes a memory leak.
 695
 696         * src/output.c (token_definitions_output): New.
 697         (output_parser, header_output): Use it.
 698         * src/reader.c (symbols_save): Remove.
 699
 700 2001-12-29  Akim Demaille  <akim@epita.fr>
 701
 702         * src/bison.simple: Do not provide a default for YYSTYPE and
 703         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
 704         default.
 705
 706 2001-12-29  Akim Demaille  <akim@epita.fr>
 707
 708         Mid-rule actions are simply... ignored!
 709
 710         * src/reader.c (readgram): Be sure to attach mid-rule actions to
 711         the empty-rule associated to the dummy symbol, not to the host
 712         rule.
 713         * tests/actions.at (Mid-rule actions): New.
 714
 715 2001-12-29  Akim Demaille  <akim@epita.fr>
 716
 717         Memory leak.
 718
 719         * src/reader.c (reader): Free grammar.
 720
 721 2001-12-29  Akim Demaille  <akim@epita.fr>
 722
 723         Memory leak.
 724
 725         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
 726         since it allocates it for each state, although only one is needed.
 727         (allocate_storage): Do it here.
 728
 729 2001-12-29  Akim Demaille  <akim@epita.fr>
 730
 731         * src/options.h, src/options.c (create_long_option_table): Rename
 732         as...
 733         (long_option_table_new): this, with a clearer prototype.
 734         (percent_table): Remove, unused,
 735         * src/getargs.c (getargs): Adjust.
 736
 737 2001-12-29  Akim Demaille  <akim@epita.fr>
 738
 739         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
 740         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 741         as states.
 742
 743 2001-12-29  Akim Demaille  <akim@epita.fr>
 744
 745         * src/lalr.c (build_relations): Rename `states' as `states1'.
 746         Sorry, I don't understand exactly what it is, no better name...
 747
 748 2001-12-29  Akim Demaille  <akim@epita.fr>

 750         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 751         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 752         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 753         as rules.
 754
 755 2001-12-29  Akim Demaille  <akim@epita.fr>
 756
 757         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 758         ago.
 759
 760 2001-12-29  Akim Demaille  <akim@epita.fr>
 761
 762         * src/reader.c, src/reader.h (user_toknums): Remove.
 763         Adjust all users to use symbols[i]->user_token_number.
 764
 765 2001-12-29  Akim Demaille  <akim@epita.fr>
 766
 767         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 768         Adjust all users to use symbols[i]->prec or ->assoc.
 769
 770 2001-12-29  Akim Demaille  <akim@epita.fr>
 771
 772         * src/reader.c, src/reader.h (tags): Remove.
 773         Adjust all users to use symbols[i]->tag.
 774
 775 2001-12-29  Akim Demaille  <akim@epita.fr>
 776
 777         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 778         and rule_table.
 779         * src/reader.c (packsymbols): Fill this table.
 780         Drop sprec.
 781         * src/conflicts.c (resolve_sr_conflict): Adjust.
 782         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 783         single table.
 784         Use symbols[i]->tag instead of tags[i].
 785
 786 2001-12-29  Akim Demaille  <akim@epita.fr>
 787
 788         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 789         In addition, put a comment in there, to replace...
 790         * tests/regression.at (%union and C comments): Remove.
 791
 792 2001-12-29  Akim Demaille  <akim@epita.fr>
 793
 794         * tests/regression.at (Web2c Actions): Blindly move the actual
 795         output as expected output.  The contents *seem* right to me, but I
 796         can't pretend reading perfectly parser tables...  Nonetheless, all
 797         the other tests pass correctly, the table look OK, even though the
 798         presence of `$axiom' is to be noted: AFAICS it is useless (but
 799         harmless).
 800
 801 2001-12-29  Akim Demaille  <akim@epita.fr>
 802
 803         * src/reader.c (readgram): Don't add the rule 0 if there were no
 804         rules read.  In other words, add it _after_ having performed
 805         grammar sanity checks.
 806         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 807
 808 2001-12-29  Akim Demaille  <akim@epita.fr>
 809
 810         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 811         visible, and some states have now a different number.
 812
 813 2001-12-29  Akim Demaille  <akim@epita.fr>
 814
 815         * src/reader.c (readgram): Bind the initial rule's lineno to that
 816         of the first rule.
 817         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 818         (Solved SR Conflicts): Adjust rule 0's line number.
 819
 820 2001-12-29  Akim Demaille  <akim@epita.fr>
 821
 822         Fix the `GAWK Grammar' failure.
 823
 824         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 825         the reductions of the first state which was mistakenly confused
 826         with the final state because precisely final_state was initialized
 827         to 0.
 828         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 829         now noticed by Bison.
 830         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 831         have a reduction on $default.
 832
 833 2001-12-29  Akim Demaille  <akim@epita.fr>
 834
 835         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 836         rule line numbers.
 837         * src/closure.c (print_closure): Likewise.
 838         * src/derives.c (print_derives): Likewise.
 839         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 840         now.
 841
 842 2001-12-29  Akim Demaille  <akim@epita.fr>
 843
 844         * src/lalr.c (lookaheads_print): New.
 845         (lalr): Call it when --trace-flag.
 846         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 847         are dumped.
 848
 849 2001-12-29  Akim Demaille  <akim@epita.fr>
 850
 851         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 852         when walking through ritem, even via rule->rhs.
 853         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 854         (useful_production, useless_nonterminals): Likewise.
 855         (reduce_grammar_tables): Likewise, plus update nritems.
 856         * src/nullable.c (set_nullable): Likewise.
 857         * src/lalr.c (build_relations): Likewise.
 858         * tests/sets.at (Nullable): Adjust.
 859         Fortunately, now, the $axiom is no longer nullable.
 860
 861 2001-12-29  Akim Demaille  <akim@epita.fr>
 862
 863         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 864         the 0-sentinel.
 865         * src/gram.c (ritem_longest_rhs): Likewise.
 866         * src/reduce.c (nonterminals_reduce): Likewise.

 868         * src/output.c (output_rule_data): Likewise.
 869         * src/nullable.c (set_nullable):  Likewise.
 870
 871 2001-12-29  Akim Demaille  <akim@epita.fr>
 872
 873         * src/output.c: Comment changes.
 874
 875 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 876
 877         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 878         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 879         Sparc, as they were causing more porting problems than the
 880         (minor) performance improvement was worth.
 881
 882         Also, catch up with 1.31's YYSTD.
 883
 884 2001-12-27  Akim Demaille  <akim@epita.fr>
 885
 886         * src/output.c (output_gram): Rely on nritems, not the
 887         0-sentinel.  See below.
 888         Use -1 as separator, not 0.
 889         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 890         Rely on -1 as separator in yyrhs, instead of 0.
 891         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 892         twice `Now at end of input', therefore there are two lines less to
 893         expect.
 894
 895 2001-12-27  Akim Demaille  <akim@epita.fr>
 896
 897         * tests/regression.at (Unresolved SR Conflicts):
 898         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 899         below.
 900
 901 2001-12-27  Akim Demaille  <akim@epita.fr>
 902
 903         * src/LR0.c (new_state): Recognize the final state by the fact it
 904         is reached by eoftoken.
 905         (insert_start_shifting_state, insert_eof_shifting_state)
 906         (insert_accepting_state, augment_automaton): Remove, since now
 907         these states are automatically computed from the initial state.
 908         (generate_states): Adjust.
 909         * src/print.c: When reporting a rule number to the user, substract
 910         1, so that the axiom rule is rule 0, and the first user rule is 1.
 911         * src/reduce.c: Likewise.
 912         * src/print_graph.c (print_core): For the time being, just as for
 913         the report, depend upon --trace-flags to dump the full set of
 914         items.
 915         * src/reader.c (readgram): Once the grammar read, insert the rule
 916         0: `$axiom: START-SYMBOL $'.
 917         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 918         number of the states has changed (the final state is no longer
 919         necessarily the last), catch up.
 920
 921 2001-12-27  Akim Demaille  <akim@epita.fr>
 922
 923         Try to make the use of the eoftoken valid.  Given that its value
 924         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 925         is used instead of > 0 where appropriate, (ii), depend upon nritems
 926         instead of the 0-sentinel.
 927
 928         * src/gram.h, src/gram.c (nritems): New.
 929         Expected to be duplication of nitems, but for the time being...
 930         * src/reader.c (packgram): Assert nritems and nitems are equal.
 931         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 932         * src/closure.c (print_closure, print_fderives): Likewise.
 933         * src/gram.c (ritem_print): Likewise.
 934         * src/print.c (print_core, print_grammar): Likewise.
 935         * src/print_graph.c: Likewise.
 936
 937 2001-12-27  Akim Demaille  <akim@epita.fr>
 938
 939         * src/main.c (main): If there are complains after grammar
 940         reductions, then output the report anyway if requested, then die.
 941         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 942         * src/reader.c (eoftoken): New.
 943         (parse_token_decl): If the token being defined has value `0', it
 944         is the eoftoken.
 945         (packsymbols): No longer hack `tags' to insert `$' by hand.
 946         Be sure to preserve the value of the eoftoken.
 947         (reader): Make sure eoftoken is defined.
 948         Initialize nsyms to 0: now eoftoken is created just like the others.
 949         * src/print.c (print_grammar): Don't special case the eof token.
 950         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 951         lie anyway, albeit pleasant.
 952         * tests/calc.at: Exercise error messages with eoftoken.
 953         Change the grammar so that empty input is invalid.
 954         Adjust expectations.
 955         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 956
 957 2001-12-27  Akim Demaille  <akim@epita.fr>
 958
 959         * configure.in: Check the protos of strchr ans strspn.
 960         Replace strchr if needed.
 961         * src/system.h: Provide the protos of strchr, strspn and memchr if
 962         missing.
 963         * lib/strchr.c: New.
 964         * src/reader.c (symbols_save): Use strchr.
 965
 966 2001-12-27  Akim Demaille  <akim@epita.fr>
 967
 968         * src/print.c, src/print_graph.c (escape): New.
 969         Use it to quote the TAGS outputs.
 970         * src/print_graph.c (print_state): Now errors are in red, and
 971         reductions in green.
 972         Prefer high to wide: output the state number on a line of its own.
 973
 974 2001-12-27  Akim Demaille  <akim@epita.fr>
 975
 976         * src/state.h, src/state.c (reductions_new): New.
 977         * src/LR0.c (set_state_table): Let all the states have a
 978         `reductions', even if reduced to 0.
 979         (save_reductions): Adjust.
 980         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 981         * src/print.c (print_reductions, print_actions): Adjust.
 982         * src/output.c (action_row): Adjust.
 983
 984 2001-12-27  Akim Demaille  <akim@epita.fr>
 985
 986         * src/state.h, src/state.c (errs_new, errs_dup): New.
 987         * src/LR0.c (set_state_table): Let all the states have an errs,
 988         even if reduced to 0.
 989         * src/print.c (print_errs, print_reductions): Adjust.
 990         * src/output.c (output_actions, action_row): Adjust.
 991         * src/conflicts.c (resolve_sr_conflict): Adjust.
 992
 993 2001-12-27  Akim Demaille  <akim@epita.fr>
 994
 995         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 996
 997 2001-12-27  Akim Demaille  <akim@epita.fr>
 998
 999         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
1000         * src/print.c: here.
1001         (lookaheadset, shiftset): New, used as additional storage by
1002         print_reductions.
1003         (print_results): Adjust.
1004         (print_shifts, print_gotos, print_errs): New, extracted from...
1005         (print_actions): here.
1006         * src/print_graph.c (print_actions): Remove dead code.
1007
1008 2001-12-27  Akim Demaille  <akim@epita.fr>
1009
1010         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
1011         `$n' and `@n'.
1012
1013 2001-12-27  Akim Demaille  <akim@epita.fr>
1014
1015         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
1016         (build_relations): Adjust.
1017
1018 2001-12-27  Akim Demaille  <akim@epita.fr>
1019
1020         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
1021         duplication.
1022
1023 2001-12-27  Akim Demaille  <akim@epita.fr>
1024
1025         * src/reader.c (packgram): Catch nitems overflows.
1026
1027 2001-12-27  Akim Demaille  <akim@epita.fr>
1028
1029         * src/files.c, src/files.h (guard_obstack): Remove.
1030         * src/output.c (output): Adjust.
1031         * src/reader.c (parse_braces): New, factoring...
1032         (copy_action, copy_guard): these two which are renamed as...
1033         (parse_action, parse_guard): these.
1034         As a voluntary consequence, using braces around guards is now
1035         mandatory.
1036
1037 2001-12-27  Akim Demaille  <akim@epita.fr>
1038
1039         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
1040         * src/reader.c (symbol_list): `guard' and `guard_line' are new
1041         members.
1042         (symbol_list_new): Adjust.
1043         (copy_action): action_line is the first line, not the last.
1044         (copy_guard): Just as for actions, store the `action' only, not
1045         the switch/case/break flesh.
1046         Don't parse the user action that might follow the guard, let...
1047         (readgram): do it, i.e., now, there can be an action after a
1048         guard.
1049         In other words the guard is just explicitly optional.
1050         (packgram): Adjust.
1051         * src/output.c (guards_output): New.
1052         (output_parser): Call it when needed.
1053         (output): Also free the guard and attrs obstacks.
1054         * src/files.c, src/files.h (obstack_save): Remove.
1055         (output_files): Remove.
1056         As a result, if one needs the former `.act' file, using an
1057         appropriate skeleton which requires actions and guards is now
1058         required.
1059         * src/main.c (main): Adjust.
1060         * tests/semantic.at: New.
1061         * tests/regression.at: Use `input.y' as input file name.
1062         Avoid 8+3 problems by requiring input.c when the test needs the
1063         parser.
1064
1065 2001-12-27  Akim Demaille  <akim@epita.fr>
1066
1067         * src/reader.c (symbol_list_new): Be sure to initialize all the
1068         fields.
1069
1070 2001-12-27  Akim Demaille  <akim@epita.fr>
1071
1072         All the hacks using a final pseudo state are now useless.
1073
1074         * src/LR0.c (set_state_table): state_table holds exactly nstates.
1075         * src/lalr.c (nLA): New.
1076         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
1077         instead of lookaheadsp from the pseudo state (nstate + 1).
1078
1079 2001-12-27  Akim Demaille  <akim@epita.fr>
1080
1081         * src/output.c (action_row, token_actions): Use a state_t instead
1082         of a integer, and nlookaheads instead of the following state's
1083         lookaheadsp.
1084
1085 2001-12-27  Akim Demaille  <akim@epita.fr>
1086
1087         * src/conflicts.c (log_resolution, flush_shift)
1088         (resolve_sr_conflict, set_conflicts, solve_conflicts)
1089         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
1090         (conflicts_print, print_reductions): Use a state_t instead of an
1091         integer when referring to a state.
1092         As much as possible, depend upon nlookaheads, instead of the
1093         `lookaheadsp' member of the following state (since lookaheads of
1094         successive states are successive, the difference between state n + 1
1095         and n served as the number of lookaheads for state n).
1096         * src/lalr.c (add_lookback_edge): Likewise.
1097         * src/print.c (print_core, print_actions, print_state)
1098         (print_results): Likewise.
1099         * src/print_graph.c (print_core, print_actions, print_state)
1100         (print_graph): Likewise.
1101         * src/conflicts.h: Adjust.

1104
1105         * src/bison.hairy: Formatting/comment changes.
1106         ANSIfy.
1107         Remove `register' indications.
1108         Add plenty of `static'.
1109
1110 2001-12-27  Akim Demaille  <akim@epita.fr>
1111
1112         * src/output.c (prepare): Drop the muscle `ntbase' which
1113         duplicates ntokens.
1114         * src/bison.simple: Formatting/comment changes.
1115         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
1116         is an undocumented synonym.
1117
1118 2001-12-22  Akim Demaille  <akim@epita.fr>
1119
1120         * src/output.c (output_table_data): Change the prototype to use
1121         `int' for array ranges: some invocations do pass an int, not a
1122         short.
1123         Reported by Wayne Green.

1127         Some actions of web2c.y are improperly triggered.
1128         Reported by Mike Castle.
1129
1130         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
1131         * tests/regression.at (Web2c): Rename as...
1132         (Web2c Report): this.
1133         (Web2c Actions): New.
1134
1135 2001-12-22  Akim Demaille  <akim@epita.fr>
1136
1137         Reductions in web2c.y are improperly reported.
1138         Reported by Mike Castle.
1139
1140         * src/conflicts.c (print_reductions): Fix.
1141         * tests/regression.at (Web2c): New.
1142
1143 2001-12-18  Akim Demaille  <akim@epita.fr>
1144
1145         Some host fail on `assert (!"foo")', which expands to
1146         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
1147         Reported by Nelson Beebee.
1148
1149         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
1150         `#define it_succeeded 0' and `assert (it_succeeded)'.
1151
1152 2001-12-17  Marc Autret  <autret_m@epita.fr>
1153
1154         * src/bison.simple: Don't hard code the skeleton line and filename.
1155         * src/output.c (output_parser): Rename 'line' as 'output_line'.
1156         New line counter 'skeleton_line' (skeleton-line muscle).
1157
1158 2001-12-17  Paul Eggert  <eggert@twinsun.com>
1159
1160         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
1161         YYDEBUG must be defined to a nonzero value.
1162
1163         * src/bison.simple (yytname): Do not assume that the user defines
1164         YYDEBUG to a properly parenthesized expression.
1165
1166 2001-12-17  Akim Demaille  <akim@epita.fr>
1167
1168         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
1169         nlookaheads is a new member.
1170         Adjust all users.
1171         * src/lalr.h (nlookaheads): Remove this orphan declaration.
1172         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
1173         state.
1174
1175 2001-12-17  Akim Demaille  <akim@epita.fr>
1176
1177         * src/files.h, src/files.c (open_files, close_files): Remove.
1178         * src/main.c (main): Don't open/close files, nor invoke lex_free,
1179         let...
1180         * src/reader.c (reader): Do it.
1181
1182 2001-12-17  Akim Demaille  <akim@epita.fr>
1183
1184         * src/conflicts.c (print_reductions): Formatting changes.
1185
1186 2001-12-17  Akim Demaille  <akim@epita.fr>
1187
1188         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
1189         (flush_reduce): New.
1190         (resolve_sr_conflict): Adjust.
1191
1192 2001-12-17  Akim Demaille  <akim@epita.fr>
1193
1194         * src/output.c (output_obstack): Be static and rename as...
1195         (format_obstack): this, to avoid any confusion with files.c's
1196         output_obstack.
1197         * src/reader.h (muscle_obstack): Move to...
1198         * src/output.h: here, since it's defined in output.c.
1199
1200 2001-12-17  Akim Demaille  <akim@epita.fr>
1201
1202         * src/output.c (action_row, save_column, default_goto)
1203         (sort_actions, matching_state, pack_vector): Better variable
1204         locality.
1205
1206 2001-12-17  Akim Demaille  <akim@epita.fr>
1207
1208         * src/output.c: Various formatting changes.
1209
1210 2001-12-17  Akim Demaille  <akim@epita.fr>
1211
1212         * src/files.c (output_files): Free the output_obstack.
1213         * src/main.c (main): Call print and print_graph conditionally.
1214         * src/print.c (print): Work unconditionally.
1215         * src/print_graph.c (print_graph): Work unconditionally.
1216         * src/conflicts.c (log_resolution): Output only if verbose_flag.
1217
1218 2001-12-16  Marc Autret  <autret_m@epita.fr>
1219
1220         * src/output.c (actions_output): Fix. When we use %no-lines,
1221         there is one less line per action.
1222
1223 2001-12-16  Marc Autret  <autret_m@epita.fr>
1224
1225         * src/bison.simple: Remove a useless #line directive.
1226         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1227         * src/output.c (get_lines_number): New.
1228         (output_parser): Adjust, now takes care about the lines of a
1229         output muscles.
1230         Fix line numbering.
1231         (actions_output): Computes the number of lines taken by actions.
1232         (output_master_parser): Insert new skeleton which is the name of
1233         the output parser file name.
1234
1235 2001-12-15  Marc Autret  <autret_m@epita.fr>
1236
1237         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
1238
1239 2001-12-15  Marc Autret  <autret_m@epita.fr>
1240
1241         * src/output.c (output_gram): Keep track of the hairy one.
1242
1243 2001-12-15  Akim Demaille  <akim@epita.fr>
1244
1245         Make `make distcheck' work.
1246
1247         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1248         system.h which uses libgettext.h.
1249
1250 2001-12-15  Akim Demaille  <akim@epita.fr>
1251
1252         * src/nullable.c (set_nullable): Useless rules must be skipped,
1253         otherwise, since we range over their symbols, we might look at a
1254         nonterminal which no longer ``exists'', i.e., it is not counted in
1255         `nvars', hence we overflow our arrays.
1256
1257 2001-12-15  Akim Demaille  <akim@epita.fr>
1258
1259         The header can also be produced directly, without any obstack!
1260         Yahoo!
1261
1262         * src/files.c, src/files.h (defines_obstack): Remove.
1263         (compute_header_macro): Global.
1264         (defines_obstack_save): Remove.
1265         * src/reader.c (parse_union_decl): No longer output to
1266         defines_obstack: its content can be found in the `stype' muscle
1267         anyway.
1268         (output_token_translations): Merge into...
1269         (symbols_output): this.
1270         Rename as...
1271         (symbols_save): this.
1272         (reader): Adjust.
1273         * src/output.c (header_output): New.
1274         (output): Call it.
1275
1276 2001-12-15  Akim Demaille  <akim@epita.fr>
1277
1278         * src/reader.c (parse_union_decl): Instead of handling two obstack
1279         simultaneously, use one to define the `stype' muscle, and use the
1280         value of the latter to fill defines_obstack.
1281         (copy_comment): Remove.
1282         (copy_comment2): Work for a single obstack.
1283         Rename as...
1284         (copy_comment): this.
1285
1286 2001-12-15  Akim Demaille  <akim@epita.fr>
1287
1288         * src/lex.c, src/lex.h (xgetc): No longer static.
1289         * src/reader.c (parse_union_decl): Revamp.
1290
1291 2001-12-15  Akim Demaille  <akim@epita.fr>
1292
1293         Still making progress in separating Bison into (i) input, (ii)
1294         process, (iii) output: now we can directly output the parser file
1295         without using table_obstack at all.
1296
1297         * src/files.c, src/files.h (table_obstack): Bye bye.
1298         (parser_file_name): New.
1299         * src/files.c (compute_output_file_names): Compute it.
1300         * src/output.c (actions_output, output_parser)
1301         (output_master_parser): To a file instead of an obstack.
1302
1303 2001-12-15  Akim Demaille  <akim@epita.fr>
1304
1305         Attach actions to rules, instead of pre-outputting them to
1306         actions_obstack.
1307
1308         * src/gram.h (rule_t): action and action_line are new members.
1309         * src/reader.c (symbol_list): Likewise.
1310         (copy_action): Save the actions within the rule.
1311         (packgram): Save them in rule_table.
1312         * src/output.c (actions_output): New.
1313         (output_parser): Use it on `%%actions'.
1314         (output_rule_data): Don't free rule_table.
1315         (output): Do it.
1316         (prepare): Don't save the `action' muscle.
1317         * src/bison.simple: s/%%action/%%actions/.
1318
1319 2001-12-15  Akim Demaille  <akim@epita.fr>
1320
1321         * src/reader.c (copy_action): When --yacc, don't append a `;'
1322         to the user action: let it fail if lacking.
1323         Suggested by Arnold Robbins and Tom Tromey.
1324
1325 2001-12-14  Akim Demaille  <akim@epita.fr>
1326
1327         * src/lex.c (literalchar): Simply return the char you decoded, non
1328         longer mess around with obstacks and int pointers.
1329         Adjust all callers.
1330
1331 2001-12-14  Akim Demaille  <akim@epita.fr>
1332
1333         * src/lex.c (literalchar): Don't escape the special characters,
1334         just decode them, and keep them as char (before, eol was output as
1335         the 2 char string `\n' etc.).
1336         * src/output.c (output_rule_data): Use quotearg to output the
1337         token strings.
1338
1339 2001-12-13  Paul Eggert  <eggert@twinsun.com>
1340
1341         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1342         Do not infringe on the global user namespace when using C++.
1343         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1344         All uses of `fprintf' and `stderr' changed.
1345
1346         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1347
1348 2001-12-13  Akim Demaille  <akim@epita.fr>
1349
1350         The computation of nullable is broken: it doesn't handle empty
1351         RHS's properly.
1352
1353         * tests/torture.at (GNU AWK Grammar): New.
1354         * tests/sets.at (Nullable): New.
1355         * src/nullable.c (set_nullable): Instead of blindly looping over
1356         `ritems', loop over the rules, and then over their rhs's.
1357
1358         Work around Autotest bugs.
1359
1360         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1361         frame, because Autotest understand lines starting with a `+' as
1362         traces from the shell.  Then, they are not processed properly.
1363         Admittedly an Autotest bug, but we don't have time to wait for
1364         Autotest to catch up.
1365         * tests/regression.at (Broken Closure): Adjust to the new table
1366         frames.
1367         Move to...
1368         * tests/sets.at: here.
1369
1370 2001-12-13  Akim Demaille  <akim@epita.fr>
1371
1372         * src/closure.c (closure): Use nrules instead of playing tricks
1373         with BITS_PER_WORD.
1374
1375 2001-12-13  Akim Demaille  <akim@epita.fr>
1376
1377         * src/print.c (print_actions): Output the handling of `$' as the
1378         traces do: shifting the token EOF.  Before EOF was treated as a
1379         nonterminal.
1380         * tests/regression.at: Adjust some tests.
1381         * src/print_graph.c (print_core): Complete the set of items via
1382         closure.  The next-to-final and final states are still unsatisfying,
1383         but that's to be addressed elsewhere.
1384         No longer output the rule numbers, but do output the state number.
1385         A single loop for the shifts + gotos is enough, but picked a
1386         distinct color for each.
1387         (print_graph): Initialize and finalize closure.
1388
1389 2001-12-13  Akim Demaille  <akim@epita.fr>
1390
1391         * src/reader.c (readgram): Remove dead code, an strip useless
1392         braces.
1393         (get_type): Remove, unused.
1394
1395 2001-12-12  Akim Demaille  <akim@epita.fr>
1396
1397         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1398         on that of lib/error.c.
1399
1400 2001-12-12  Akim Demaille  <akim@epita.fr>
1401
1402         Some hosts don't like `/' in includes.
1403
1404         * src/system.h: Include libgettext.h without qualifying the path.
1405         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1406         $(top_srcdir).
1407
1408 2001-12-11  Marc Autret  <autret_m@epita.fr>
1409
1410         * src/output.c (output_parser): Remove useless muscle.
1411
1412 2001-12-11  Marc Autret  <autret_m@epita.fr>
1413
1414         * src/bison.simple: Remove #line just before %%epilogue. It
1415         is now handled in ...
1416         * src/reader.c (read_additionnal_code): Add the output of a
1417         #line for the epilogue.
1418
1419 2001-12-10  Marc Autret  <autret_m@epita.fr>
1420
1421         * src/reader.c (copy_definition): Re-use CPP-outed code which
1422         replace precedent remove.
1423         * src/bison.simple: Remove #line before %%prologue because
1424         %%input-line is wrong at this time.
1425
1426 2001-12-10  Marc Autret  <autret_m@epita.fr>
1427
1428         * src/reader.c (symbols_output): Clean up.
1429         * src/output.c (output_gram, output): Clean up.
1430
1431 2001-12-10  Akim Demaille  <akim@epita.fr>
1432
1433         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
1434         * src/LR0.c (set_state_table): here.
1435         * src/lalr.c (lalr): Call it.
1436
1437 2001-12-10  Akim Demaille  <akim@epita.fr>
1438
1439         * src/state.h (shifts): Remove the `number' member: shifts are
1440         attached to state, hence no longer need to be labelled with a
1441         state number.
1442
1443 2001-12-10  Akim Demaille  <akim@epita.fr>
1444
1445         Now that states have a complete set of members, the linked list of
1446         shifts is useless: just fill directly the state's shifts member.
1447
1448         * src/state.h (shifts): Remove the `next' member.
1449         * src/LR0.c (first_state, last_state): Remove.
1450         Adjust the callers.
1451         (augment_automaton): Don't look for the shifts that must be added
1452         a shift on EOF: it is those of the state we looked for!  But now,
1453         since shifts are attached, it is no longer needed to looking
1454         merely by its id: its number.

1456 2001-12-10  Akim Demaille  <akim@epita.fr>
1457
1458         * src/LR0.c (augment_automaton): Better variable locality.
1459         Remove an impossible branch: if there is a state corresponding to
1460         the start symbol being shifted, then there is shift for the start
1461         symbol from the initial state.
1462
1463 2001-12-10  Akim Demaille  <akim@epita.fr>
1464
1465         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1466         only when appropriate: when insert_start_shifting_state' is not
1467         invoked.
1468         * tests/regression.at (Rule Line Numbers): Adjust.
1469
1470 2001-12-10  Akim Demaille  <akim@epita.fr>
1471
1472         * src/LR0.c (augment_automaton): Now that all states have shifts,
1473         merge the two cases addition shifts to the initial state.
1474
1475 2001-12-10  Akim Demaille  <akim@epita.fr>
1476
1477         * src/lalr.c (set_state_table): Move to...
1478         * src/LR0.c: here.
1479         * src/lalr.c (lalr): Don't call it...
1480         * src/LR0.c (generate_states): do it.
1481         * src/LR0.h (first_state): Remove, only the table is used.
1482
1483 2001-12-10  Akim Demaille  <akim@epita.fr>
1484
1485         * src/LR0.h (first_shift, first_reduction): Remove.
1486         * src/lalr.c: Don't use first_shift: find shifts through the
1487         states.
1488
1489 2001-12-10  Akim Demaille  <akim@epita.fr>
1490
1491         * src/LR0.c: Attach shifts to states as soon as they are
1492         computed.
1493         * src/lalr.c (set_state_table): Instead of assigning shifts to
1494         state, just assert that the mapping was properly done.
1495
1496 2001-12-10  Akim Demaille  <akim@epita.fr>
1497
1498         * src/LR0.c (insert_start_shift): Rename as...
1499         (insert_start_shifting_state): this.
1500         (insert_eof_shifting_state, insert_accepting_state): New.
1501         (augment_automaton): Adjust.
1502         Better locality of the variables.
1503         When looking if the start_symbol is shifted from the initial
1504         state, using `while (... symbol != start_symbol ...)' sounds
1505         better than `while (... symbol < start_symbol ...)': If fail
1506         to see how the order between symbols could be relevant!
1507
1508 2001-12-10  Akim Demaille  <akim@epita.fr>
1509
1510         * src/getargs.h: Don't declare `spec_name_prefix' and
1511         `spec_file_prefix', declared by src/files.h.
1512         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1513         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1514         * src/output.c (prepare): Adjust.
1515         * src/reader.c (symbols_output): Likewise.
1516         * src/vmsgetargs.c: Vaguely adjust, but who cares?
1517
1518 2001-12-10  Akim Demaille  <akim@epita.fr>
1519
1520         * src/muscle_tab.c (muscle_init): NULL is a better default than
1521         `"0"'.
1522
1523 2001-12-10  Akim Demaille  <akim@epita.fr>
1524
1525         * src/reader.c (reader): Calling symbols_output once is enough.
1526
1527 2001-12-10  Akim Demaille  <akim@epita.fr>
1528
1529         Now that states have a complete set of members, the linked list of
1530         reductions is useless: just fill directly the state's reductions
1531         member.
1532
1533         * src/state.h (struct reductions): Remove member `number' and
1534         `next'.
1535         * src/LR0.c (first_reduction, last_reduction): Remove.
1536         (save_reductions): Don't link the new reductions, store them in
1537         this_state.
1538         * src/lalr.c (set_state_table): No need to attach reductions to
1539         states, it's already done.
1540         * src/output.c (output_actions): No longer free the shifts, then
1541         the reductions, then the states: free all the states and their
1542         members.
1543
1544 2001-12-10  Akim Demaille  <akim@epita.fr>
1545
1546         * src/options.c (OPTN, DRTV, BOTH): New.
1547         (option_table): Use them.
1548
1549         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1550         the job of system.h.
1551         * src/options.c: Don't include stdio.h and xalloc.h for the same
1552         reasons.
1553
1554 2001-12-10  Akim Demaille  <akim@epita.fr>
1555
1556         * src/output.c (output, prepare): Make sure the values of the
1557         muscles `action' and `prologue' are 0-terminated.
1558
1559 2001-12-10  Akim Demaille  <akim@epita.fr>
1560
1561         Clean up GCC warnings.
1562
1563         * src/reader.c (copy_action): `buf' is not used.
1564         (parse_skel_decl): Be static.
1565         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1566         * src/options.h (create_long_option_table): Have a real prototype.
1567         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1568         (hash_delete_at): Return const void *.
1569         Adjust casts to preserve the const.
1570
1571 2001-12-10  Akim Demaille  <akim@epita.fr>
1572
1573         * configure.in: Require 2.52g.
1574         M4 is not needed, but AUTOM4TE is.
1575         * m4/m4.m4: Remove.
1576         * tests/Makefile.am: Adjust.
1577
1578 2001-12-10  Akim Demaille  <akim@epita.fr>
1579
1580         One structure for states is enough, even though theoretically
1581         there are LR(0) states and LALR(1) states.
1582
1583         * src/lalr.h (state_t): Remove.
1584         (state_table): Be state_t **, not state_t *.
1585         * src/state.h (core, CORE_ALLOC): Rename as...
1586         (state_t, STATE_ALLOC): this.
1587         Add the LALR(1) members: shifts, reductions, errs.
1588         * src/LR0.c (state_table): Rename as...
1589         (state_hash): this, to avoid name clashes with the global
1590         `state_table'.
1591         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1592         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
1593
1594 2001-12-10  Akim Demaille  <akim@epita.fr>
1595
1596         Bison dumps core on bash.y.
1597         Reported by Pascal Bart.
1598
1599         * src/warshall.c (bitmatrix_print): New.
1600         (TC): Use it.
1601         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1602         j must be the outer loop.
1603         * tests/regression.at (Broken Closure): New.
1604
1605 2001-12-05  Akim Demaille  <akim@epita.fr>
1606
1607         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1608         its argument.
1609         Reported by Peter Hámorský.
1610
1611 2001-12-05  Akim Demaille  <akim@epita.fr>
1612
1613         * src/conflicts.c (err_table): Remove.
1614         (resolve_sr_conflict): Adjust.
1615         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1616         Rename as...
1617         (state_t.reductions, state_t.shifts): this.
1618
1619 2001-12-05  Akim Demaille  <akim@epita.fr>
1620
1621         * src/reduce.c (reduce_grammar_tables): No longer disable the
1622         removal of useless rules via CPP but via `if (0)', so that the
1623         compiler still check the code is valid.
1624         For instance, it should have noticed `rline' no longer exists: use
1625         the `line' member of rule_t.
1626         * src/gram.c (dummy, rline): Remove, unused.
1627
1628 2001-12-05  Akim Demaille  <akim@epita.fr>
1629
1630         * src/output.c (pack_vector): Use assert, not berror.
1631         * src/main.c (berror): Remove, unused.
1632
1633 2001-12-05  Akim Demaille  <akim@epita.fr>
1634
1635         New experimental feature: if --verbose --trace output all the
1636         items of a state, not only its kernel.
1637
1638         * src/print.c (print_core): If `trace_flag', then invoke closure
1639         before outputting the items of the state (print_core is no longer
1640         a correct name them).
1641         (print_results): Invoke new_closure/free_closure if needed.
1642
1643 2001-12-05  Akim Demaille  <akim@epita.fr>
1644
1645         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1646         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1647         (nitemset): for consistency with the rest of the project.
1648
1649 2001-12-05  Akim Demaille  <akim@epita.fr>
1650
1651         * src/closure.c (print_closure): Improve.
1652         (closure): Use it for printing input and output.
1653
1654 2001-12-05  Akim Demaille  <akim@epita.fr>
1655
1656         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1657         indexed by nonterminals.
1658
1659 2001-12-05  Akim Demaille  <akim@epita.fr>
1660
1661         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1662         what it was!).
1663         * src/warshall.h: Remove accidental duplication of the content.
1664
1665 2001-12-05  Akim Demaille  <akim@epita.fr>
1666
1667         * src/closure.c (set_fderives): De-obfuscate.
1668
1669 2001-12-05  Akim Demaille  <akim@epita.fr>
1670
1671         * src/closure.c (print_firsts, print_fderives): De-obfuscate.

1676
1677 2001-12-05  Akim Demaille  <akim@epita.fr>
1678
1679         * src/output.c (action_row): De-obfuscate
1680         using the good o' techniques: arrays not pointers, variable
1681         locality, BITISSET, RESETBIT etc.
1682
1683 2001-12-05  Akim Demaille  <akim@epita.fr>
1684
1685         Pessimize the code to simplify it: from now on, all the states
1686         have a valid SHIFTS, which NSHIFTS is possibly 0.
1687
1688         * src/LR0.c (shifts_new): Be global and move to..
1689         * src/state.c, src/state.h: here.
1690         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1691         * src/print_graph: Adjust.
1692
1693 2001-12-05  Akim Demaille  <akim@epita.fr>
1694
1695         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1696         * src/conflicts.c: Use it.
1697         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1698         incorrectly ``simplified''.
1699
1700 2001-12-05  Akim Demaille  <akim@epita.fr>
1701
1702         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1703         using the good o' techniques: arrays not pointers, variable
1704         locality, BITISSET, RESETBIT etc.
1705
1706 2001-12-05  Akim Demaille  <akim@epita.fr>
1707
1708         * src/state.h (SHIFT_SYMBOL): New.
1709         * src/conflicts.c: Use it to deobfuscate.
1710
1711 2001-12-05  Akim Demaille  <akim@epita.fr>
1712
1713         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1714         (print_reductions): De-obfuscate using the good o' techniques:
1715         arrays not pointers, variable locality, BITISSET.
1716
1717 2001-12-05  Akim Demaille  <akim@epita.fr>
1718
1719         * src/conflicts.c (print_reductions): Arrays, not pointers.
1720         Use BITISSET.
1721
1722 2001-12-05  Akim Demaille  <akim@epita.fr>
1723
1724         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1725
1726 2001-12-05  Akim Demaille  <akim@epita.fr>
1727
1728         * src/conflicts.c (print_reductions): Improve variable locality.
1729
1730 2001-12-05  Akim Demaille  <akim@epita.fr>
1731
1732         * src/conflicts.c (print_reductions): Pessimize, but clarify.

1739
1740         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
1741         * src/lalr.c: Use them.
1742
1743 2001-12-05  Akim Demaille  <akim@epita.fr>
1744
1745         * src/LR0.c (augment_automaton): Formatting changes.
1746         Better variable locality.
1747
1748 2001-12-05  Akim Demaille  <akim@epita.fr>
1749
1750         * src/lalr.c (matrix_print): New.
1751         (transpose): Use it.
1752         Use arrays instead of pointers.
1753
1754 2001-12-05  Akim Demaille  <akim@epita.fr>
1755
1756         * src/lalr.c (maxrhs): Move to...
1757         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1758         * src/lalr.c (build_relations): Adjust.
1759
1760 2001-12-05  Akim Demaille  <akim@epita.fr>
1761
1762         * src/lalr.c (transpose): Free the memory allocated to the
1763         argument, as it is replaced by the results by the unique caller.
1764         (build_relations): Merely invoke transpose: it handles the memory
1765         deallocation.
1766         Improve variable locality.
1767         Avoid variables used as mere abbreviations.
1768         (compute_lookaheads): Use arrays instead of pointers.
1769
1770 2001-12-05  Akim Demaille  <akim@epita.fr>
1771
1772         * src/lalr.c (initialize_F): Improve variable locality.

1774
1775 2001-12-05  Akim Demaille  <akim@epita.fr>
1776
1777         * src/derives.c (print_derives): Display the ruleno.
1778         * src/lalr.c (initialize_F, transpose): Better variable locality
1779         to improve readability.
1780         Avoid variables used as mere abbreviations.
1781
1782 2001-12-05  Akim Demaille  <akim@epita.fr>
1783
1784         * src/lalr.c (traverse): Use arrays instead of pointers.
1785
1786 2001-12-05  Akim Demaille  <akim@epita.fr>
1787
1788         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1789         the handling of squeue.
1790         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1791
1792 2001-12-05  Akim Demaille  <akim@epita.fr>
1793
1794         Because useless nonterminals are now kept alive (instead of being
1795         `destroyed'), we now sometimes examine them, and store information
1796         related to them.  Hence we need to know their number, and adjust
1797         memory allocations.
1798
1799         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1800         static.
1801         * src/LR0.c (allocate_itemsets): The memory allocated to
1802         `symbol_count' was used for two different purpose: once to count
1803         the number of occurrences of each symbol, and later reassigned to
1804         `shift_symbol', containing the symbol that can be shifted from a
1805         given state.
1806         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1807         only, and...
1808         (new_itemsets): Allocate `shift_symbol' here.
1809         (allocate_itemsets): symbol_count includes useless nonterminals.
1810         Make room for them.
1811         (free_storage): Use `free', not `XFREE', for pointers that cannot
1812         be null.

1816         * src/nullable.c (set_nullable): Deobfuscate the handling of
1817         ritem.
1818         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1819
1820 2001-12-05  Akim Demaille  <akim@epita.fr>
1821
1822         * src/gram.c, src/gram.h (ritem_print): New.
1823         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1824         (This useless function was defined only to work around VMS linkers
1825         that can't handle compilation units with variables only).
1826         * src/reduce.c (dump_grammar): Use it to trace the construction of
1827         ritem.
1828
1829 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1830
1831         * src/bison.simple (union yyalloc): Change member names
1832         to be the same as the stack names.
1833         (yyparse): yyptr is now union yyalloc *, not char *.
1834         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1835         and may generate better code on some machines.
1836         (yystpcpy): Use prototype if __STDC__ is defined, not just
1837         if __cplusplus is defined.
1838
1839 2001-11-30  Akim Demaille  <akim@epita.fr>
1840
1841         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1842         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1843         Gettext doesn't compile cleanly, and dies with -Werror.
1844         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1845         Include WARNING_CFLAGS here.
1846         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1847         before being defined.
1848
1849 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1850
1851         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1852         First arg is int, not unsigned.
1853         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1854         (SIZE_MAX, UINT_MAX): New macros.
1855         (quotearg_n_options): Abort if N is negative.
1856         Avoid overflow check on hosts where size_t is 64 bits and int
1857         is 32 bits, as overflow is impossible there.
1858         Fix off-by-one typo that caused unnecessary reallocation.
1859
1860 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1861
1862         Name space cleanup in generated parser.
1863
1864         * doc/bison.texinfo (Bison Parser): Discuss system headers
1865         and their effect on the user name space.
1866
1867         * src/bison.simple:
1868         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1869         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1870         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1871
1872         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1873         on user names when possible.
1874
1875         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1876         Simplify test for whather <alloca.h> exists.
1877
1878         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1879
1880         (<stdio.h>): Include if YYDEBUG.
1881
1882         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless

1884
1885         (yymemcpy, yyparse): Rename local variables as needed so that

1887
1888         (yystrlen, yystpcpy): New functions.
1889
1890         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1891         All uses changed.
1892
1893         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1894         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1895         and YYSTACK_FREE instead of malloc and free.
1896
1897 2001-11-30  Akim Demaille  <akim@epita.fr>
1898
1899         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
1900         before their first uses.

1906
1907 2001-11-30  Akim Demaille  <akim@epita.fr>
1908
1909         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1910         if body instead of `;' to pacify GCC's warnings.
1911
1912 2001-11-30  Akim Demaille  <akim@epita.fr>
1913
1914         Instead of mapping the LHS of unused rules to -1, keep the LHS
1915         valid, but flag the rules as invalid.
1916
1917         * src/gram.h (rule_t): `useful' is a new member.
1918         * src/print.c (print_grammar): Adjust.

1921         * src/reduce.c (reduce_grammar_tables): Likewise.
1922         * tests/reduce.at (Underivable Rules, Useless Rules): New.

1930
1931 2001-11-30  Akim Demaille  <akim@epita.fr>
1932
1933         * src/reduce.c (nonterminals_reduce): Instead of throwing away
1934         useless nonterminals, move them at the end of the symbol arrays.

1936         * tests/reduce.at (Useless Nonterminals): Adjust.
1937

1941         (nonterminals_reduce): New, extracted from...
1942         (reduce_grammar_tables): here.
1943         (reduce_grammar): Call nonterminals_reduce.
1944
1945 2001-11-29  Paul Eggert  <eggert@twinsun.com>

1948         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
1949         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
1950         New macros.
1951         (union yyalloc): New type.
1952         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1953         an arbitrary restriction on hosts where size_t is wider than int.
1954
1955         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1956         a parser stack overflow.  Allocate just one block of memory for all
1957         three stacks, instead of allocating three blocks; this typically is
1958         faster and reduces fragmentation.
1959
1960         Do not limit the number of items in the stack to a value that fits
1961         in 'int', as this is an arbitrary limit on hosts with 64-bit
1962         size_t and 32-bit int.
1963
1964 2001-11-29  Marc Autret  <autret_m@epita.fr>

2015         keep ruleno only.
2016
2017 2001-11-28  Akim Demaille  <akim@epita.fr>
2018
2019         * src/closure.c (closure): Instead of looping over word in array
2020         then bits in words, loop over bits in array.
2021
2022 2001-11-28  Akim Demaille  <akim@epita.fr>
2023
2024         * src/closure.c (closure): No longer optimize the special case
2025         where all the bits of `ruleset[r]' are set to 0, to make the code
2026         clearer.
2027

2029

2051         * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
2052         use alloca when we didn't want to, and vice versa.

2122
2123         * src/reader.c (read_declarations): Don't abort on tok_illegal,

2156         * src/LR0.c (kernel_size): Contain `int' instead of `size_t' to
2157         pacify GCC's signed < unsigned warnings.

2161 2001-11-23  Akim Demaille  <akim@epita.fr>
2162
2163         Attaching lineno to buckets is stupid, since only one copy of each
2164         symbol is kept, only the line of the first occurrence is kept too.
2165
2166         * src/symtab.h, src/symtab.c (bucket): Remove the line member.

3341
3342         * src/bison.simple (yyparse): Don't take the address of an

3352         completely wrong.

3391         bound to true.
3392         (read_declarations): Add case for macro definition.
3393         (copy_identifier): New.
3394         (parse_macro_decl): Read macro identifiers using copy_identifier

3401         (output_parser): Fix bug on '%%line' directives.

3414         table with a macro. No output to the table obstack.
3415         (output_gram): Same for 'rhs' and 'prhs'.

3429         with something new. Skeletons are now processed character by character
3430         rather than line by line, and Bison looks for '%%' macros. This is the
3431         first step in making Bison's output process (a lot) more flexible.
3432         (output_parser): Use the macro table.

3760
3761         * src/reader.c (gensym): `gensym_count' is your own.
3762         Use a static buf to create the symbol name, as token_buffer is no
3763         longer a buffer.
3764
3765 2001-02-08  Akim Demaille  <akim@epita.fr>
3766
3767         * src/conflicts.c (conflict_report): Be sure not to append to res
3768         between two calls, which could happen if both first sprintf were

3774         New, from fileutils 4.0.37.
3775         * configure.in: Require Autoconf 2.49c.  I took some time before
3776         making this decision.  This is the only way out for portability
3777         issues in Bison, it would mean way too much duplicate effort to
3778         import in Bison features implemented in 2.49c since 2.13.
3779         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

3790
3791         * src/lex.c (token_obstack): New.
3792         (init_lex): Initialize it.  No longer call...

3797
3798         * src/lex.h: Rename all the tokens:

3800         s/\bIDENTIFIER\b/tok_identifier/g;
3801         etc.
3802         Let them be enums, not #define, to ease debugging.
3803         Adjust all the code.
3804
3805 2001-01-18  Akim Demaille  <akim@epita.fr>
3806
3807         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

3809
3810 2001-01-18  Akim Demaille  <akim@epita.fr>
3811
3812         Since we now use obstacks, more % directives can be enabled.
3813
3814         * src/lex.c (percent_table): Also accept `%yacc',
3815         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3816         `%debug'.
3817         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3818         instead of returning a token.
3819         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3820         * src/reader.c (read_declarations): Adjust.
3821         * src/files.c (open_files): Don't call `compute_base_names', don't
3822         compute `attrsfile' since they depend upon data which might be
3823         *in* the input file now.
3824         (output_files): Do it here.
3825         * src/output.c (output_headers): Document the fact that this patch
3826         introduces a guaranteed SEGV for semantic parsers.

3851         FILE * parameters.
3852
3853 2000-12-20  Akim Demaille  <akim@epita.fr>
3854
3855         * src/files.c (open_files): Actually the `.output' file is based
3856         on the short_base_name, not base_name.
3857         * tests/suite.at (Checking output file names): Adjust.
3858
3859 2000-12-20  Akim Demaille  <akim@epita.fr>
3860
3861         * src/bison.s1: Remove, we now use directly...

3885         (stringappend): Be just like strcat but allocate.
3886         (base_names): Eve out from open_files.
3887         Try to simplify the rather hairy computation of base_name and
3888         short_base_name.
3889         (open_files): Use it.
3890         * tests/suite.at (Checking output file names): New test.

3900
3901 2000-12-19  Akim Demaille  <akim@epita.fr>
3902

3904         there are.
3905         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.

3907
3908 2000-12-19  Akim Demaille  <akim@epita.fr>
3909
3910         Let the handling of the skeleton files be local to the procedures
3911         that use it.

3956         to escape special characters when outputting filenames.
3957         (ACTSTR_PROLOGUE, ACTSTR_EPILOGUE): Remove.

3961
3962         * lib/obstack.h: Formatting changes.
3963         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3964         prevents type checking.
3965         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3966         cast the value to (void *): assigning a `foo *' to a `void *'
3967         variable is valid.
3968         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3969         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

4050         it no longer has to remove tmp files, just call `output_files'
4051         when there are no errors.

4158         Reported by Piotr Gackiewicz, and fixed by Neil Booth.

4161         Include the core of the sample provided by Piotr Gackiewicz.

4172
4173         * bison.s1 (yyparse): Assign the default value
4174         unconditionally, to avoid a GCC warning and make the parser a
4175         tad smaller.
4176
4177 2000-10-02  Akim Demaille  <akim@epita.fr>
4178

4186
4187 2000-10-02  Akim Demaille  <akim@epita.fr>
4188
4189         The location tracking mechanism is precious for parse error
4190         messages.  Nevertheless, it is enabled only when `@n' is used in
4191         the grammar, which is a different issue (you can use it in error
4192         message, but not in the grammar per se).  Therefore, there should
4193         be another means to enable it.
4194
4195         * src/getargs.c (getargs): Support `--locations'.
4196         (usage): Report it.
4197         * src/getargs.h (locationsflag): Export it.
4198         * src/lex.c (percent_table): Support `%locations'.
4199         * src/reader.c (yylsp_needed): Remove this variable, now replaced
4200         with `locationsflag'.
4201         * doc/bison.texinfo: Document `--locations' and `%locations'.
4202         Sort the options.
4203         * tests/calc.m4: Test it.
4204
4205         For regularity of the names, replace each
4206         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4207         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4208         In addition replace each `flag' with `_flag'.
4209
4210 2000-10-02  Akim Demaille  <akim@epita.fr>
4211
4212         Also test parse error messages, including with YYERROR_VERBOSE.
4213
4214         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4215         associative).
4216         Use it to check the computations.
4217         Use it to check `nonassoc' is honored.
4218         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4219         `--yyerror-verbose'.
4220         (_AT_CHECK_CALC): Adjust to this option.
4221         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4222
4223 2000-10-02  Akim Demaille  <akim@epita.fr>
4224
4225         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
4226         the latter demonstrates a flaw in the handling of non debugging
4227         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4228         was used in order to simplify:
4229
4230         #if YYDEBUG
4231         if (yydebug)
4232         {
4233         ...
4234         }
4235         #endif
4236
4237         into
4238
4239         if (yydebug)
4240         {
4241         ...
4242         }
4243
4244         unfortunately this leads to a CPP conflict when
4245         `--name-prefix=foo' is used since it produces `#define yydebug
4246         foodebug'.
4247
4248         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4249         (YYDPRINTF): New macro.
4250         Spread its use.
4251         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4252         the bison options.
4253         Also test `--verbose', `--defines' and `--name-prefix'.
4254
4255 2000-10-02  Akim Demaille  <akim@epita.fr>
4256
4257         Improve the readability of the produced parsers.
4258
4259         * src/bison.s1: Formatting changes.
4260         Improve the comment related to the `$' mark.
4261         (yydefault): Don't fall through to `yyresume': `goto' there.
4262         * src/output.c (output_parser): When the `$' is met, skip the end
4263         of its line.
4264         New variable, `number_of_dollar_signs', to check there's exactly
4265         one `$' in the parser skeleton.
4266
4267 2000-10-02  Akim Demaille  <akim@epita.fr>
4268
4269         * lib/xstrdup.c: New file, from the fileutils.
4270         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4271         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4272         instead of strlen + xmalloc + strcpy.
4273         * src/symtab.c (copys): Remove, use xstrdup instead.
4274
4275 2000-10-02  Akim Demaille  <akim@epita.fr>
4276
4277         * src/gram.h (associativity): New enum type which replaces the
4278         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4279         `right_assoc', `left_assoc' and `non_assoc'.
4280         Adjust all dependencies.
4281         * src/reader.c: Formatting changes.
4282         (LTYPESTR): Don't define it, use it as a literal in
4283         `reader_output_yylsp'.
4284         * src/symtab.h (symbol_class): New enum type which replaces the
4285         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4286         `sunknown', `stoken and `snterm'.
4287
4288 2000-10-02  Akim Demaille  <akim@epita.fr>
4289
4290         * src/getargs.c (fixed_outfiles): Rename as...
4291         (yaccflag): for consistency and accuracy.
4292         Adjust dependencies.
4293
4294 2000-10-02  Akim Demaille  <akim@epita.fr>
4295
4296         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4297         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4298         difficult and introduced a lot of core dump.  It turns out that
4299         Bison used an implementation of `xmalloc' based on `calloc', and
4300         at various places it does depend upon the initialization to 0.  I
4301         have not tried to isolate the pertinent places, and all the former
4302         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4303         someone should address this issue.

4406         `user_toknums' is output as a `short[]' in `output.c', while it is

4452         * src/system.h: Define PARAMS.
4453         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

4455         definitions in config.h.

4672
4673         Change the handling of @s so that they behave exactly like $s.
4674         There is now a pseudo variable @$ (readble and writable), location
4675         of the lhs of the rule (by default ranging from the location of
4676         the first symbol of the rhs, to the location of the last symbol,
4677         or, if the rhs is empty, YYLLOC).
4678
4679         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4680         yyval.
4681         (yyparse): When providing a default semantic action, provide a
4682         default location action.
4683         (after the $): No longer change `*YYLSP', just stack YYLOC the
4684         same way you stack YYVAL.
4685         * src/reader.c (read_declarations): Use warns.
4686         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4687         (copy_action, case '@'): Likewise.
4688         Use a standard error message, to save useless work from
4689         translators.
4690
4691 2000-03-17  Akim Demaille  <akim@epita.fr>
4692
4693         * src/bison.s1: Formatting and cosmetics changes.

4710
4711         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4712         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4713         One `#if YYDEBUG' remains, since it uses variables which are
4714         defined only if `YYDEBUG != 0'.
4715

4740         handled via src/Makefile.am.

4742         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
4743         autoheader.

4748         the proper line number and file name.
4749         (DEFS): Propagate the location of bison library files and of the
4750         locale files.
4751         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4752         builddir.
4753         * acinclude.m4: Remove, replaced by the directory m4.
4754         * m4/Makefile.am (EXTRA_DIST): New variable.
4755         * m4/gettext.m4: New file, from the fileutils.
