 168 2002-02-14  Paul Eggert  <eggert@twinsun.com>
 169
 170         Remove the support for C++ namespace cleanliness; it was
 171         causing more problems than it was curing, since it didn't work
 172         properly on some nonstandard C++ compilers.  This can wait
 173         for a proper C++ parser.
 174
 175         * NEWS: Document this.
 176         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention

 192
 193         * src/output.c (output_rule_data): Don't output NULL, it might
 194         not be defined yet.

 214
 215 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 216
 217         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
 218         more consistent when naming methods and variables.  Put preprocessor
 219         directives around tables only needed for debugging.
 220
 221 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>

 241 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
 242
 243         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
 244         not expanded by m4.
 245
 246 2002-02-05  Akim Demaille  <akim@epita.fr>
 247
 248         * data/bison.c++: Adjust to the M4 back end.

 262         * src/output.c (actions_output, guards_output)
 263         (token_definitions_output): No longer keeps track of the output
 264         line number, hence remove the second argument.
 265         (guards_output): Check against the guard member of a rule, not the
 266         action member.
 267         Adjust callers.
 268         (output_skeleton): Don't look for the skeleton location, let m4 do
 269         that.
 270         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
 271         file will be used.
 272         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
 273         (prepare): Given that for the time being changesyntax is not
 274         usable in M4, rename the muscles using `-' to `_'.
 275         Define `defines_flag', `output_parser_name' and `output_header_name'.

 280         * data/bison.simple: Adjust to be used by M4(sugar).
 281         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
 282         to date.
 283         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
 284         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
 285         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
 286         shamelessly stolen from CVS Autoconf.

 303
 304 2002-01-29  Paul Eggert  <eggert@twinsun.com>
 305
 306         * src/bison.simple (YYSIZE_T): Do not define merely because
 307         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 308         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 309
 310 2002-01-27  Akim Demaille  <akim@epita.fr>

 317         with
 318         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
 319         !!!

 333         forces `.' in the PATH.

 377         compilers as well (i.e. the vendor C compiler).
 378         Suggested by Albert Chin-A-Young.
 379
 380 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
 381
 382         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
 383         canonical definition.
 384         * src/system.h: Use the canonical definition for PARAMS (avoids
 385         a conflict with the macro from lib/hash.h).
 386
 387 2002-01-11  Akim Demaille  <akim@epita.fr>
 388
 389         * configure.in: Use AC_FUNC_STRNLEN.
 390         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
 391
 392 2002-01-09  Akim Demaille  <akim@epita.fr>
 393
 394         * src/files.c, src/files.h (output_infix): New.
 395         (tab_extension): Remove.
 396         (compute_base_names): Compute the former, drop the latter.
 397         * src/output.c (prepare): Insert the muscles `output-infix', and
 398         `output-suffix'.
 399         * src/parse-skel.y (string, string.1): New.
 400         (section.header): Use it.
 401         (section.yacc): Remove.
 402         (prefix): Remove too.
 403         * src/scan-skel.l: Adjust.
 404         * src/bison.simple, src/bison.hairy: Adjust.
 405
 406 2002-01-09  Akim Demaille  <akim@epita.fr>
 407
 408         * configure.in (WERROR_CFLAGS): Compute it.
 409         * src/Makefile.am (CFLAGS): Pass it.
 410         * tests/atlocal.in (CFLAGS): Idem.
 411         * src/files.c: Fix a few warnings.
 412         (get_extension_index): Remove, unused.
 413
 414 2002-01-08  Akim Demaille  <akim@epita.fr>
 415
 416         * src/getargs.c (AS_FILE_NAME): New.
 417         (getargs): Use it to convert DOSish file names.
 418         * src/files.c (base_name): Rename as full_base_name to avoid
 419         clashes with `base_name ()'.
 420         (filename_split): New.
 421         (compute_base_names): N-th rewrite, using filename_split.
 422
 423 2002-01-08  Akim Demaille  <akim@epita.fr>
 424
 425         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
 426         New, stolen from the Fileutils 4.1.
 427         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
 428         * configure.in: Check for the presence of memrchr, and of its
 429         prototype.
 430
 431 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
 432
 433         * lib/hash.h (__P): Added definition for this macro.
 434         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
 435         BUILT_SOURCES, to ensure they are generated first.
 436         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
 437         %error-verbose to allow bootstrapping with bison 1.30x.
 438
 439 2002-01-06  Akim Demaille  <akim@epita.fr>
 440
 441         * src/reader.c (parse_braces): Don't fetch the next char, the
 442         convention is to fetch on entry.
 443         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
 444         'switch' without a following semicolon.
 445         * tests/regression.at (braces parsing): New.
 446
 447 2002-01-06  Akim Demaille  <akim@epita.fr>
 448
 449         Bison is dead wrong in its RR conflict reports.
 450
 451         * tests/torture.at (GNU Cim Grammar): New.
 452         * src/conflicts.c (count_rr_conflicts): Fix.
 453
 454 2002-01-06  Akim Demaille  <akim@epita.fr>
 455
 456         Creating package.m4 from configure.ac causes too many problems.
 457
 458         * tests/Makefile.am (package.m4): Create it by hand,
 459         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
 460
 461 2002-01-06  Akim Demaille  <akim@epita.fr>
 462
 463         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
 464         skeleton.h.
 465
 466 2002-01-04  Paul Eggert  <eggert@twinsun.com>
 467
 468         * doc/bison.texinfo (Debugging):
 469         Remove YYSTDERR; it's no longer defined or used.
 470         Also, s/cstdio.h/cstdio/.
 471
 472 2002-01-03  Akim Demaille  <akim@epita.fr>
 473
 474         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
 475
 476 2002-01-03  Akim Demaille  <akim@epita.fr>
 477
 478         * src/parse-skel.y (process_skeleton): Don't bind the parser's
 479         tracing code to --trace, wait for a better --trace option, with
 480         args.
 481
 482 2002-01-03  Akim Demaille  <akim@epita.fr>
 483
 484         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
 485         The ISO C++ standard is extremely clear about it: stderr is
 486         considered a macro, not a regular symbol (see table 94 `Header
 487         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
 488         Therefore std:: does not apply to it.  It still does with fprintf.
 489         Also, s/cstdio.h/cstdio/.
 490
 491 2002-01-03  Akim Demaille  <akim@epita.fr>
 492
 493         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
 494         for non system headers.
 495
 496 2002-01-02  Akim Demaille  <akim@epita.fr>
 497
 498         Equip the skeleton chain with location tracking, runtime trace,
 499         pure parser and scanner.
 500
 501         * src/parse-skel.y: Request a pure parser, locations, and prefix
 502         renaming.
 503         (%union): Having several members with the same type does not help
 504         type mismatches, simplify.
 505         (YYPRINT, yyprint): New.
 506         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
 507         (skel_error): this.
 508         Handle locations.
 509         * src/scan-skel.l: Adjust to these changes.
 510         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
 511         (LOCATION_PRINT, skel_control_t): New.
 512
 513 2001-12-30  Akim Demaille  <akim@epita.fr>
 514
 515         * src/parse-skel.y: Get rid of the shift/reduce conflict:
 516         replace `gb' with BLANKS.
 517         * src/scan-skel.l: Adjust.
 518
 519 2001-12-30  Akim Demaille  <akim@epita.fr>
 520
 521         * src/system.h: We don't need nor want bcopy.
 522         Throw away MS-DOS crap: we don't need getpid.
 523         * configure.in: We don't need strndup.  It was even causing
 524         problems: because Flex includes the headers *before* us,
 525         _GNU_SOURCE is not defined by config.h, and therefore strndup was
 526         not visible.
 527         * lib/xstrndup.c: New.
 528         * src/scan-skel.l: Use it.
 529         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
 530         * src/parse-skel.y: Use %directives instead of #defines.
 531
 532 2001-12-30  Akim Demaille  <akim@epita.fr>
 533
 534         * src/skeleton.h: New.
 535         * src/output.c (output_parser, output_master_parser): Remove, dead
 536         code.
 537         * src/output.h (get_lines_number, actions_output, guards_output)
 538         (token_definitions_output): Prototype them.
 539         * src/parse-skel.y: Add the license notice.
 540         Include output.h and skeleton.h.
 541         (process_skeleton): Returns void, and takes a single parameter.
 542         * src/scan-skel.l: Add the license notice.
 543         Include skeleton.h.
 544         Don't use %option yylineno: it seems that then Flex imagines
 545         REJECT has been used, and therefore it won't reallocate its
 546         buffers (which makes no other sense to me than a bug).  It results
 547         in warnings for `unused: yy_flex_realloc'.
 548
 549 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
 550
 551         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 552         (MUSCLE_INSERT_PREFIX): ...to there.
 553         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 554         (MUSCLE_INSERT_PREFIX): Move from here...
 555
 556         * src/bison.hairy: Add a section directive.  Put braces around muscle
 557         names.  This parser skeleton is still broken, but Bison should not
 558         choke on a bad muscle 'syntax'.
 559         * src/bison.simple: Add a section directive.  Put braces around muscle
 560         names.
 561
 562         * src/files.h (strsuffix, stringappend): Add declarations.
 563         (tab_extension): Add declaration.
 564         (short_base_name): Add declaration.
 565
 566         * src/files.c (strsuffix, stringappend): No longer static.  These
 567         functions are used in the skeleton parser.
 568         (tab_extension): New.
 569         (compute_base_names): Use the computations done in this function
 570         to guess if the generated parsers should have '.tab' in their
 571         names.
 572         (short_base_name): No longer static.
 573
 574         * src/output.c (output_skeleton): New.
 575         (output): Disable call to output_master_parser, and give a try to
 576         a new skeleton handling system.
 577         (guards_output, actions_output): No longer static.
 578         (token_definitions_output, get_lines_number): No longer static.
 579
 580         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
 581
 582         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
 583         parse-skel.y.
 584
 585         * src/parse-skel.y: New file.
 586         * src/scan-skel.l: New file.
 587
 588 2001-12-29  Akim Demaille  <akim@epita.fr>
 589
 590         %name-prefix is broken.
 591
 592         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
 593         Adjust all dependencies.
 594         * tests/headers.at (export YYLTYPE): Strengthen this test: use
 595         %name-prefix.
 596
 597         Renaming yylval but not yylloc is not consistent.  Now we do.
 598
 599         * src/bison.simple: Prefix yylloc if used.
 600         * doc/bison.texinfo (Decl Summary): Document that.
 601
 602 2001-12-29  Akim Demaille  <akim@epita.fr>
 603
 604         * doc/bison.texinfo: Promote `%long-directive' over
 605         `%long_directive'.
 606         Remove all references to fixed-output-files, yacc is enough.
 607
 608 2001-12-29  Akim Demaille  <akim@epita.fr>
 609
 610         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
 611         user prologue.  These are defaults.
 612         * tests/actions.at (Mid-rule actions): Make sure the user can
 613         define YYDEBUG and YYERROR_VERBOSE.
 614
 615 2001-12-29  Akim Demaille  <akim@epita.fr>
 616
 617         * src/output.c (header_output): Don't forget to export YYLTYPE and
 618         yylloc.
 619         * tests/headers.at (export YYLTYPE): New, make sure it does.
 620         * tests/regression.at (%union and --defines, Invalid CPP headers):
 621         Move to...
 622         * tests/headers.at: here.
 623
 624 2001-12-29  Akim Demaille  <akim@epita.fr>
 625
 626         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
 627
 628 2001-12-29  Akim Demaille  <akim@epita.fr>
 629
 630         * tests/actions.at (Mid-rule actions): Output on a single line
 631         instead of several.
 632
 633 2001-12-29  Akim Demaille  <akim@epita.fr>
 634
 635         * doc/bison.texinfo: Formatting changes.
 636
 637 2001-12-29  Akim Demaille  <akim@epita.fr>
 638
 639         Don't store the token defs in a muscle, just be ready to output it
 640         on command.  Now possible via `symbols'.  Fixes a memory leak.
 641
 642         * src/output.c (token_definitions_output): New.
 643         (output_parser, header_output): Use it.
 644         * src/reader.c (symbols_save): Remove.
 645
 646 2001-12-29  Akim Demaille  <akim@epita.fr>
 647
 648         * src/bison.simple: Do not provide a default for YYSTYPE and
 649         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
 650         default.
 651
 652 2001-12-29  Akim Demaille  <akim@epita.fr>
 653
 654         Mid-rule actions are simply... ignored!
 655
 656         * src/reader.c (readgram): Be sure to attach mid-rule actions to
 657         the empty-rule associated to the dummy symbol, not to the host
 658         rule.
 659         * tests/actions.at (Mid-rule actions): New.
 660
 661 2001-12-29  Akim Demaille  <akim@epita.fr>
 662
 663         Memory leak.
 664
 665         * src/reader.c (reader): Free grammar.
 666
 667 2001-12-29  Akim Demaille  <akim@epita.fr>
 668
 669         Memory leak.
 670
 671         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
 672         since it allocates it for each state, although only one is needed.
 673         (allocate_storage): Do it here.
 674
 675 2001-12-29  Akim Demaille  <akim@epita.fr>
 676
 677         * src/options.h, src/options.c (create_long_option_table): Rename
 678         as...
 679         (long_option_table_new): this, with a clearer prototype.
 680         (percent_table): Remove, unused,
 681         * src/getargs.c (getargs): Adjust.
 682
 683 2001-12-29  Akim Demaille  <akim@epita.fr>
 684
 685         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
 686         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 687         as states.
 688
 689 2001-12-29  Akim Demaille  <akim@epita.fr>
 690
 691         * src/lalr.c (build_relations): Rename `states' as `states1'.
 692         Sorry, I don't understand exactly what it is, no better name...
 693
 694 2001-12-29  Akim Demaille  <akim@epita.fr>
 695
 696         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 697         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 698         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 699         as rules.
 700
 701 2001-12-29  Akim Demaille  <akim@epita.fr>
 702
 703         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 704         ago.
 705
 706 2001-12-29  Akim Demaille  <akim@epita.fr>
 707
 708         * src/reader.c, src/reader.h (user_toknums): Remove.
 709         Adjust all users to use symbols[i]->user_token_number.
 710
 711 2001-12-29  Akim Demaille  <akim@epita.fr>
 712
 713         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 714         Adjust all users to use symbols[i]->prec or ->assoc.
 715
 716 2001-12-29  Akim Demaille  <akim@epita.fr>
 717
 718         * src/reader.c, src/reader.h (tags): Remove.
 719         Adjust all users to use symbols[i]->tag.
 720
 721 2001-12-29  Akim Demaille  <akim@epita.fr>
 722
 723         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 724         and rule_table.
 725         * src/reader.c (packsymbols): Fill this table.
 726         Drop sprec.
 727         * src/conflicts.c (resolve_sr_conflict): Adjust.
 728         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 729         single table.
 730         Use symbols[i]->tag instead of tags[i].
 731
 732 2001-12-29  Akim Demaille  <akim@epita.fr>
 733
 734         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 735         In addition, put a comment in there, to replace...
 736         * tests/regression.at (%union and C comments): Remove.
 737
 738 2001-12-29  Akim Demaille  <akim@epita.fr>
 739
 740         * tests/regression.at (Web2c Actions): Blindly move the actual
 741         output as expected output.  The contents *seem* right to me, but I
 742         can't pretend reading perfectly parser tables...  Nonetheless, all
 743         the other tests pass correctly, the table look OK, even though the
 744         presence of `$axiom' is to be noted: AFAICS it is useless (but
 745         harmless).
 746
 747 2001-12-29  Akim Demaille  <akim@epita.fr>

 749         * src/reader.c (readgram): Don't add the rule 0 if there were no
 750         rules read.  In other words, add it _after_ having performed
 751         grammar sanity checks.
 752         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 753
 754 2001-12-29  Akim Demaille  <akim@epita.fr>
 755
 756         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 757         visible, and some states have now a different number.
 758
 759 2001-12-29  Akim Demaille  <akim@epita.fr>
 760
 761         * src/reader.c (readgram): Bind the initial rule's lineno to that
 762         of the first rule.
 763         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 764         (Solved SR Conflicts): Adjust rule 0's line number.
 765
 766 2001-12-29  Akim Demaille  <akim@epita.fr>
 767
 768         Fix the `GAWK Grammar' failure.
 769
 770         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 771         the reductions of the first state which was mistakenly confused
 772         with the final state because precisely final_state was initialized
 773         to 0.
 774         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 775         now noticed by Bison.
 776         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 777         have a reduction on $default.
 778
 779 2001-12-29  Akim Demaille  <akim@epita.fr>
 780
 781         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 782         rule line numbers.
 783         * src/closure.c (print_closure): Likewise.
 784         * src/derives.c (print_derives): Likewise.
 785         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 786         now.
 787
 788 2001-12-29  Akim Demaille  <akim@epita.fr>
 789
 790         * src/lalr.c (lookaheads_print): New.
 791         (lalr): Call it when --trace-flag.
 792         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 793         are dumped.
 794
 795 2001-12-29  Akim Demaille  <akim@epita.fr>
 796
 797         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 798         when walking through ritem, even via rule->rhs.
 799         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 800         (useful_production, useless_nonterminals): Likewise.
 801         (reduce_grammar_tables): Likewise, plus update nritems.
 802         * src/nullable.c (set_nullable): Likewise.
 803         * src/lalr.c (build_relations): Likewise.
 804         * tests/sets.at (Nullable): Adjust.
 805         Fortunately, now, the $axiom is no longer nullable.
 806
 807 2001-12-29  Akim Demaille  <akim@epita.fr>
 808
 809         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 810         the 0-sentinel.
 811         * src/gram.c (ritem_longest_rhs): Likewise.
 812         * src/reduce.c (nonterminals_reduce): Likewise.

 817 2001-12-29  Akim Demaille  <akim@epita.fr>
 818
 819         * src/output.c: Comment changes.
 820
 821 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 822
 823         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 824         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 825         Sparc, as they were causing more porting problems than the
 826         (minor) performance improvement was worth.
 827
 828         Also, catch up with 1.31's YYSTD.
 829
 830 2001-12-27  Akim Demaille  <akim@epita.fr>
 831
 832         * src/output.c (output_gram): Rely on nritems, not the
 833         0-sentinel.  See below.
 834         Use -1 as separator, not 0.
 835         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 836         Rely on -1 as separator in yyrhs, instead of 0.
 837         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 838         twice `Now at end of input', therefore there are two lines less to
 839         expect.
 840
 841 2001-12-27  Akim Demaille  <akim@epita.fr>
 842
 843         * tests/regression.at (Unresolved SR Conflicts):
 844         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 845         below.
 846
 847 2001-12-27  Akim Demaille  <akim@epita.fr>
 848
 849         * src/LR0.c (new_state): Recognize the final state by the fact it
 850         is reached by eoftoken.
 851         (insert_start_shifting_state, insert_eof_shifting_state)
 852         (insert_accepting_state, augment_automaton): Remove, since now
 853         these states are automatically computed from the initial state.
 854         (generate_states): Adjust.
 855         * src/print.c: When reporting a rule number to the user, substract
 856         1, so that the axiom rule is rule 0, and the first user rule is 1.
 857         * src/reduce.c: Likewise.
 858         * src/print_graph.c (print_core): For the time being, just as for
 859         the report, depend upon --trace-flags to dump the full set of
 860         items.
 861         * src/reader.c (readgram): Once the grammar read, insert the rule
 862         0: `$axiom: START-SYMBOL $'.
 863         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 864         number of the states has changed (the final state is no longer
 865         necessarily the last), catch up.
 866
 867 2001-12-27  Akim Demaille  <akim@epita.fr>
 868
 869         Try to make the use of the eoftoken valid.  Given that its value
 870         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 871         is used instead of > 0 where appropriate, (ii), depend upon nritems
 872         instead of the 0-sentinel.
 873
 874         * src/gram.h, src/gram.c (nritems): New.
 875         Expected to be duplication of nitems, but for the time being...
 876         * src/reader.c (packgram): Assert nritems and nitems are equal.
 877         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 878         * src/closure.c (print_closure, print_fderives): Likewise.
 879         * src/gram.c (ritem_print): Likewise.
 880         * src/print.c (print_core, print_grammar): Likewise.
 881         * src/print_graph.c: Likewise.
 882
 883 2001-12-27  Akim Demaille  <akim@epita.fr>
 884
 885         * src/main.c (main): If there are complains after grammar
 886         reductions, then output the report anyway if requested, then die.
 887         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 888         * src/reader.c (eoftoken): New.
 889         (parse_token_decl): If the token being defined has value `0', it
 890         is the eoftoken.
 891         (packsymbols): No longer hack `tags' to insert `$' by hand.
 892         Be sure to preserve the value of the eoftoken.
 893         (reader): Make sure eoftoken is defined.
 894         Initialize nsyms to 0: now eoftoken is created just like the others.
 895         * src/print.c (print_grammar): Don't special case the eof token.
 896         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 897         lie anyway, albeit pleasant.
 898         * tests/calc.at: Exercise error messages with eoftoken.
 899         Change the grammar so that empty input is invalid.
 900         Adjust expectations.
 901         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 902
 903 2001-12-27  Akim Demaille  <akim@epita.fr>
 904
 905         * configure.in: Check the protos of strchr ans strspn.
 906         Replace strchr if needed.
 907         * src/system.h: Provide the protos of strchr, strspn and memchr if
 908         missing.
 909         * lib/strchr.c: New.
 910         * src/reader.c (symbols_save): Use strchr.
 911
 912 2001-12-27  Akim Demaille  <akim@epita.fr>
 913
 914         * src/print.c, src/print_graph.c (escape): New.
 915         Use it to quote the TAGS outputs.
 916         * src/print_graph.c (print_state): Now errors are in red, and
 917         reductions in green.
 918         Prefer high to wide: output the state number on a line of its own.
 919
 920 2001-12-27  Akim Demaille  <akim@epita.fr>
 921
 922         * src/state.h, src/state.c (reductions_new): New.
 923         * src/LR0.c (set_state_table): Let all the states have a
 924         `reductions', even if reduced to 0.
 925         (save_reductions): Adjust.
 926         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 927         * src/print.c (print_reductions, print_actions): Adjust.
 928         * src/output.c (action_row): Adjust.
 929
 930 2001-12-27  Akim Demaille  <akim@epita.fr>
 931
 932         * src/state.h, src/state.c (errs_new, errs_dup): New.
 933         * src/LR0.c (set_state_table): Let all the states have an errs,
 934         even if reduced to 0.
 935         * src/print.c (print_errs, print_reductions): Adjust.
 936         * src/output.c (output_actions, action_row): Adjust.
 937         * src/conflicts.c (resolve_sr_conflict): Adjust.
 938
 939 2001-12-27  Akim Demaille  <akim@epita.fr>
 940
 941         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 942
 943 2001-12-27  Akim Demaille  <akim@epita.fr>
 944
 945         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 946         * src/print.c: here.
 947         (lookaheadset, shiftset): New, used as additional storage by
 948         print_reductions.
 949         (print_results): Adjust.
 950         (print_shifts, print_gotos, print_errs): New, extracted from...
 951         (print_actions): here.
 952         * src/print_graph.c (print_actions): Remove dead code.
 953
 954 2001-12-27  Akim Demaille  <akim@epita.fr>
 955
 956         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 957         `$n' and `@n'.
 958
 959 2001-12-27  Akim Demaille  <akim@epita.fr>
 960
 961         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 962         (build_relations): Adjust.
 963
 964 2001-12-27  Akim Demaille  <akim@epita.fr>
 965
 966         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 967         duplication.
 968
 969 2001-12-27  Akim Demaille  <akim@epita.fr>
 970
 971         * src/reader.c (packgram): Catch nitems overflows.
 972
 973 2001-12-27  Akim Demaille  <akim@epita.fr>
 974
 975         * src/files.c, src/files.h (guard_obstack): Remove.
 976         * src/output.c (output): Adjust.
 977         * src/reader.c (parse_braces): New, factoring...
 978         (copy_action, copy_guard): these two which are renamed as...
 979         (parse_action, parse_guard): these.
 980         As a voluntary consequence, using braces around guards is now
 981         mandatory.
 982
 983 2001-12-27  Akim Demaille  <akim@epita.fr>
 984
 985         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 986         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 987         members.
 988         (symbol_list_new): Adjust.
 989         (copy_action): action_line is the first line, not the last.
 990         (copy_guard): Just as for actions, store the `action' only, not
 991         the switch/case/break flesh.
 992         Don't parse the user action that might follow the guard, let...
 993         (readgram): do it, i.e., now, there can be an action after a
 994         guard.
 995         In other words the guard is just explicitly optional.
 996         (packgram): Adjust.
 997         * src/output.c (guards_output): New.
 998         (output_parser): Call it when needed.
 999         (output): Also free the guard and attrs obstacks.
1000         * src/files.c, src/files.h (obstack_save): Remove.
1001         (output_files): Remove.
1002         As a result, if one needs the former `.act' file, using an
1003         appropriate skeleton which requires actions and guards is now
1004         required.
1005         * src/main.c (main): Adjust.
1006         * tests/semantic.at: New.
1007         * tests/regression.at: Use `input.y' as input file name.
1008         Avoid 8+3 problems by requiring input.c when the test needs the
1009         parser.
1010
1011 2001-12-27  Akim Demaille  <akim@epita.fr>
1012
1013         * src/reader.c (symbol_list_new): Be sure to initialize all the
1014         fields.
1015
1016 2001-12-27  Akim Demaille  <akim@epita.fr>
1017
1018         All the hacks using a final pseudo state are now useless.
1019
1020         * src/LR0.c (set_state_table): state_table holds exactly nstates.
1021         * src/lalr.c (nLA): New.
1022         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
1023         instead of lookaheadsp from the pseudo state (nstate + 1).
1024
1025 2001-12-27  Akim Demaille  <akim@epita.fr>
1026
1027         * src/output.c (action_row, token_actions): Use a state_t instead
1028         of a integer, and nlookaheads instead of the following state's
1029         lookaheadsp.
1030
1031 2001-12-27  Akim Demaille  <akim@epita.fr>
1032
1033         * src/conflicts.c (log_resolution, flush_shift)
1034         (resolve_sr_conflict, set_conflicts, solve_conflicts)
1035         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
1036         (conflicts_print, print_reductions): Use a state_t instead of an
1037         integer when referring to a state.
1038         As much as possible, depend upon nlookaheads, instead of the
1039         `lookaheadsp' member of the following state (since lookaheads of
1040         successive states are successive, the difference between state n + 1
1041         and n served as the number of lookaheads for state n).
1042         * src/lalr.c (add_lookback_edge): Likewise.
1043         * src/print.c (print_core, print_actions, print_state)
1044         (print_results): Likewise.
1045         * src/print_graph.c (print_core, print_actions, print_state)
1046         (print_graph): Likewise.
1047         * src/conflicts.h: Adjust.
1048
1049 2001-12-27  Akim Demaille  <akim@epita.fr>
1050
1051         * src/bison.hairy: Formatting/comment changes.
1052         ANSIfy.
1053         Remove `register' indications.
1054         Add plenty of `static'.
1055
1056 2001-12-27  Akim Demaille  <akim@epita.fr>
1057
1058         * src/output.c (prepare): Drop the muscle `ntbase' which
1059         duplicates ntokens.
1060         * src/bison.simple: Formatting/comment changes.
1061         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
1062         is an undocumented synonym.
1063
1064 2001-12-22  Akim Demaille  <akim@epita.fr>
1065
1066         * src/output.c (output_table_data): Change the prototype to use
1067         `int' for array ranges: some invocations do pass an int, not a
1068         short.
1069         Reported by Wayne Green.

1073         Some actions of web2c.y are improperly triggered.
1074         Reported by Mike Castle.
1075
1076         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
1077         * tests/regression.at (Web2c): Rename as...
1078         (Web2c Report): this.
1079         (Web2c Actions): New.
1080
1081 2001-12-22  Akim Demaille  <akim@epita.fr>
1082
1083         Reductions in web2c.y are improperly reported.
1084         Reported by Mike Castle.
1085
1086         * src/conflicts.c (print_reductions): Fix.
1087         * tests/regression.at (Web2c): New.
1088
1089 2001-12-18  Akim Demaille  <akim@epita.fr>
1090
1091         Some host fail on `assert (!"foo")', which expands to
1092         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
1093         Reported by Nelson Beebee.
1094
1095         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
1096         `#define it_succeeded 0' and `assert (it_succeeded)'.
1097
1098 2001-12-17  Marc Autret  <autret_m@epita.fr>
1099
1100         * src/bison.simple: Don't hard code the skeleton line and filename.
1101         * src/output.c (output_parser): Rename 'line' as 'output_line'.
1102         New line counter 'skeleton_line' (skeleton-line muscle).
1103
1104 2001-12-17  Paul Eggert  <eggert@twinsun.com>
1105
1106         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
1107         YYDEBUG must be defined to a nonzero value.
1108
1109         * src/bison.simple (yytname): Do not assume that the user defines
1110         YYDEBUG to a properly parenthesized expression.
1111
1112 2001-12-17  Akim Demaille  <akim@epita.fr>
1113
1114         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
1115         nlookaheads is a new member.
1116         Adjust all users.
1117         * src/lalr.h (nlookaheads): Remove this orphan declaration.
1118         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
1119         state.
1120
1121 2001-12-17  Akim Demaille  <akim@epita.fr>
1122
1123         * src/files.h, src/files.c (open_files, close_files): Remove.
1124         * src/main.c (main): Don't open/close files, nor invoke lex_free,
1125         let...
1126         * src/reader.c (reader): Do it.
1127
1128 2001-12-17  Akim Demaille  <akim@epita.fr>
1129
1130         * src/conflicts.c (print_reductions): Formatting changes.
1131
1132 2001-12-17  Akim Demaille  <akim@epita.fr>
1133
1134         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
1135         (flush_reduce): New.
1136         (resolve_sr_conflict): Adjust.
1137
1138 2001-12-17  Akim Demaille  <akim@epita.fr>
1139
1140         * src/output.c (output_obstack): Be static and rename as...
1141         (format_obstack): this, to avoid any confusion with files.c's
1142         output_obstack.
1143         * src/reader.h (muscle_obstack): Move to...
1144         * src/output.h: here, since it's defined in output.c.
1145
1146 2001-12-17  Akim Demaille  <akim@epita.fr>
1147
1148         * src/output.c (action_row, save_column, default_goto)
1149         (sort_actions, matching_state, pack_vector): Better variable
1150         locality.
1151
1152 2001-12-17  Akim Demaille  <akim@epita.fr>
1153
1154         * src/output.c: Various formatting changes.
1155
1156 2001-12-17  Akim Demaille  <akim@epita.fr>
1157
1158         * src/files.c (output_files): Free the output_obstack.
1159         * src/main.c (main): Call print and print_graph conditionally.
1160         * src/print.c (print): Work unconditionally.
1161         * src/print_graph.c (print_graph): Work unconditionally.
1162         * src/conflicts.c (log_resolution): Output only if verbose_flag.
1163
1164 2001-12-16  Marc Autret  <autret_m@epita.fr>
1165
1166         * src/output.c (actions_output): Fix. When we use %no-lines,
1167         there is one less line per action.
1168
1169 2001-12-16  Marc Autret  <autret_m@epita.fr>
1170
1171         * src/bison.simple: Remove a useless #line directive.
1172         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1173         * src/output.c (get_lines_number): New.
1174         (output_parser): Adjust, now takes care about the lines of a
1175         output muscles.
1176         Fix line numbering.
1177         (actions_output): Computes the number of lines taken by actions.
1178         (output_master_parser): Insert new skeleton which is the name of
1179         the output parser file name.
1180
1181 2001-12-15  Marc Autret  <autret_m@epita.fr>
1182
1183         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
1184
1185 2001-12-15  Marc Autret  <autret_m@epita.fr>
1186
1187         * src/output.c (output_gram): Keep track of the hairy one.
1188
1189 2001-12-15  Akim Demaille  <akim@epita.fr>
1190
1191         Make `make distcheck' work.
1192
1193         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1194         system.h which uses libgettext.h.
1195
1196 2001-12-15  Akim Demaille  <akim@epita.fr>
1197
1198         * src/nullable.c (set_nullable): Useless rules must be skipped,
1199         otherwise, since we range over their symbols, we might look at a
1200         nonterminal which no longer ``exists'', i.e., it is not counted in
1201         `nvars', hence we overflow our arrays.
1202
1203 2001-12-15  Akim Demaille  <akim@epita.fr>
1204
1205         The header can also be produced directly, without any obstack!
1206         Yahoo!
1207
1208         * src/files.c, src/files.h (defines_obstack): Remove.
1209         (compute_header_macro): Global.
1210         (defines_obstack_save): Remove.
1211         * src/reader.c (parse_union_decl): No longer output to
1212         defines_obstack: its content can be found in the `stype' muscle
1213         anyway.
1214         (output_token_translations): Merge into...
1215         (symbols_output): this.
1216         Rename as...
1217         (symbols_save): this.
1218         (reader): Adjust.
1219         * src/output.c (header_output): New.
1220         (output): Call it.
1221
1222 2001-12-15  Akim Demaille  <akim@epita.fr>
1223
1224         * src/reader.c (parse_union_decl): Instead of handling two obstack
1225         simultaneously, use one to define the `stype' muscle, and use the
1226         value of the latter to fill defines_obstack.
1227         (copy_comment): Remove.
1228         (copy_comment2): Work for a single obstack.
1229         Rename as...
1230         (copy_comment): this.
1231
1232 2001-12-15  Akim Demaille  <akim@epita.fr>
1233
1234         * src/lex.c, src/lex.h (xgetc): No longer static.
1235         * src/reader.c (parse_union_decl): Revamp.
1236
1237 2001-12-15  Akim Demaille  <akim@epita.fr>
1238
1239         Still making progress in separating Bison into (i) input, (ii)
1240         process, (iii) output: now we can directly output the parser file
1241         without using table_obstack at all.
1242
1243         * src/files.c, src/files.h (table_obstack): Bye bye.
1244         (parser_file_name): New.
1245         * src/files.c (compute_output_file_names): Compute it.
1246         * src/output.c (actions_output, output_parser)
1247         (output_master_parser): To a file instead of an obstack.
1248
1249 2001-12-15  Akim Demaille  <akim@epita.fr>
1250
1251         Attach actions to rules, instead of pre-outputting them to
1252         actions_obstack.
1253
1254         * src/gram.h (rule_t): action and action_line are new members.
1255         * src/reader.c (symbol_list): Likewise.
1256         (copy_action): Save the actions within the rule.
1257         (packgram): Save them in rule_table.
1258         * src/output.c (actions_output): New.
1259         (output_parser): Use it on `%%actions'.
1260         (output_rule_data): Don't free rule_table.
1261         (output): Do it.
1262         (prepare): Don't save the `action' muscle.
1263         * src/bison.simple: s/%%action/%%actions/.
1264
1265 2001-12-15  Akim Demaille  <akim@epita.fr>
1266
1267         * src/reader.c (copy_action): When --yacc, don't append a `;'
1268         to the user action: let it fail if lacking.
1269         Suggested by Arnold Robbins and Tom Tromey.
1270
1271 2001-12-14  Akim Demaille  <akim@epita.fr>
1272
1273         * src/lex.c (literalchar): Simply return the char you decoded, non
1274         longer mess around with obstacks and int pointers.
1275         Adjust all callers.
1276
1277 2001-12-14  Akim Demaille  <akim@epita.fr>
1278
1279         * src/lex.c (literalchar): Don't escape the special characters,
1280         just decode them, and keep them as char (before, eol was output as
1281         the 2 char string `\n' etc.).
1282         * src/output.c (output_rule_data): Use quotearg to output the
1283         token strings.
1284
1285 2001-12-13  Paul Eggert  <eggert@twinsun.com>
1286
1287         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1288         Do not infringe on the global user namespace when using C++.
1289         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1290         All uses of `fprintf' and `stderr' changed.
1291
1292         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1293
1294 2001-12-13  Akim Demaille  <akim@epita.fr>
1295
1296         The computation of nullable is broken: it doesn't handle empty
1297         RHS's properly.
1298
1299         * tests/torture.at (GNU AWK Grammar): New.
1300         * tests/sets.at (Nullable): New.
1301         * src/nullable.c (set_nullable): Instead of blindly looping over
1302         `ritems', loop over the rules, and then over their rhs's.
1303
1304         Work around Autotest bugs.
1305
1306         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1307         frame, because Autotest understand lines starting with a `+' as
1308         traces from the shell.  Then, they are not processed properly.
1309         Admittedly an Autotest bug, but we don't have time to wait for
1310         Autotest to catch up.
1311         * tests/regression.at (Broken Closure): Adjust to the new table
1312         frames.
1313         Move to...
1314         * tests/sets.at: here.
1315
1316 2001-12-13  Akim Demaille  <akim@epita.fr>
1317
1318         * src/closure.c (closure): Use nrules instead of playing tricks
1319         with BITS_PER_WORD.
1320
1321 2001-12-13  Akim Demaille  <akim@epita.fr>
1322
1323         * src/print.c (print_actions): Output the handling of `$' as the
1324         traces do: shifting the token EOF.  Before EOF was treated as a
1325         nonterminal.
1326         * tests/regression.at: Adjust some tests.
1327         * src/print_graph.c (print_core): Complete the set of items via
1328         closure.  The next-to-final and final states are still unsatisfying,
1329         but that's to be addressed elsewhere.
1330         No longer output the rule numbers, but do output the state number.
1331         A single loop for the shifts + gotos is enough, but picked a
1332         distinct color for each.
1333         (print_graph): Initialize and finalize closure.
1334
1335 2001-12-13  Akim Demaille  <akim@epita.fr>
1336
1337         * src/reader.c (readgram): Remove dead code, an strip useless
1338         braces.
1339         (get_type): Remove, unused.
1340
1341 2001-12-12  Akim Demaille  <akim@epita.fr>
1342
1343         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1344         on that of lib/error.c.
1345
1346 2001-12-12  Akim Demaille  <akim@epita.fr>
1347
1348         Some hosts don't like `/' in includes.
1349
1350         * src/system.h: Include libgettext.h without qualifying the path.
1351         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1352         $(top_srcdir).
1353
1354 2001-12-11  Marc Autret  <autret_m@epita.fr>
1355
1356         * src/output.c (output_parser): Remove useless muscle.
1357
1358 2001-12-11  Marc Autret  <autret_m@epita.fr>
1359
1360         * src/bison.simple: Remove #line just before %%epilogue. It
1361         is now handled in ...
1362         * src/reader.c (read_additionnal_code): Add the output of a
1363         #line for the epilogue.
1364
1365 2001-12-10  Marc Autret  <autret_m@epita.fr>
1366
1367         * src/reader.c (copy_definition): Re-use CPP-outed code which
1368         replace precedent remove.
1369         * src/bison.simple: Remove #line before %%prologue because
1370         %%input-line is wrong at this time.
1371
1372 2001-12-10  Marc Autret  <autret_m@epita.fr>
1373
1374         * src/reader.c (symbols_output): Clean up.
1375         * src/output.c (output_gram, output): Clean up.
1376
1377 2001-12-10  Akim Demaille  <akim@epita.fr>
1378
1379         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
1380         * src/LR0.c (set_state_table): here.
1381         * src/lalr.c (lalr): Call it.
1382
1383 2001-12-10  Akim Demaille  <akim@epita.fr>
1384
1385         * src/state.h (shifts): Remove the `number' member: shifts are
1386         attached to state, hence no longer need to be labelled with a
1387         state number.
1388
1389 2001-12-10  Akim Demaille  <akim@epita.fr>
1390
1391         Now that states have a complete set of members, the linked list of
1392         shifts is useless: just fill directly the state's shifts member.
1393
1394         * src/state.h (shifts): Remove the `next' member.
1395         * src/LR0.c (first_state, last_state): Remove.
1396         Adjust the callers.
1397         (augment_automaton): Don't look for the shifts that must be added
1398         a shift on EOF: it is those of the state we looked for!  But now,
1399         since shifts are attached, it is no longer needed to looking
1400         merely by its id: its number.
1401
1402 2001-12-10  Akim Demaille  <akim@epita.fr>
1403
1404         * src/LR0.c (augment_automaton): Better variable locality.
1405         Remove an impossible branch: if there is a state corresponding to
1406         the start symbol being shifted, then there is shift for the start
1407         symbol from the initial state.
1408
1409 2001-12-10  Akim Demaille  <akim@epita.fr>
1410
1411         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1412         only when appropriate: when insert_start_shifting_state' is not
1413         invoked.
1414         * tests/regression.at (Rule Line Numbers): Adjust.
1415
1416 2001-12-10  Akim Demaille  <akim@epita.fr>
1417
1418         * src/LR0.c (augment_automaton): Now that all states have shifts,
1419         merge the two cases addition shifts to the initial state.
1420
1421 2001-12-10  Akim Demaille  <akim@epita.fr>
1422
1423         * src/lalr.c (set_state_table): Move to...
1424         * src/LR0.c: here.
1425         * src/lalr.c (lalr): Don't call it...
1426         * src/LR0.c (generate_states): do it.
1427         * src/LR0.h (first_state): Remove, only the table is used.
1428
1429 2001-12-10  Akim Demaille  <akim@epita.fr>
1430
1431         * src/LR0.h (first_shift, first_reduction): Remove.
1432         * src/lalr.c: Don't use first_shift: find shifts through the
1433         states.
1434
1435 2001-12-10  Akim Demaille  <akim@epita.fr>
1436
1437         * src/LR0.c: Attach shifts to states as soon as they are
1438         computed.
1439         * src/lalr.c (set_state_table): Instead of assigning shifts to
1440         state, just assert that the mapping was properly done.
1441
1442 2001-12-10  Akim Demaille  <akim@epita.fr>
1443
1444         * src/LR0.c (insert_start_shift): Rename as...
1445         (insert_start_shifting_state): this.
1446         (insert_eof_shifting_state, insert_accepting_state): New.
1447         (augment_automaton): Adjust.
1448         Better locality of the variables.
1449         When looking if the start_symbol is shifted from the initial
1450         state, using `while (... symbol != start_symbol ...)' sounds
1451         better than `while (... symbol < start_symbol ...)': If fail
1452         to see how the order between symbols could be relevant!
1453

1456         * src/getargs.h: Don't declare `spec_name_prefix' and
1457         `spec_file_prefix', declared by src/files.h.
1458         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1459         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1460         * src/output.c (prepare): Adjust.
1461         * src/reader.c (symbols_output): Likewise.
1462         * src/vmsgetargs.c: Vaguely adjust, but who cares?
1463
1464 2001-12-10  Akim Demaille  <akim@epita.fr>
1465
1466         * src/muscle_tab.c (muscle_init): NULL is a better default than
1467         `"0"'.
1468
1469 2001-12-10  Akim Demaille  <akim@epita.fr>
1470
1471         * src/reader.c (reader): Calling symbols_output once is enough.
1472
1473 2001-12-10  Akim Demaille  <akim@epita.fr>
1474
1475         Now that states have a complete set of members, the linked list of
1476         reductions is useless: just fill directly the state's reductions
1477         member.
1478
1479         * src/state.h (struct reductions): Remove member `number' and
1480         `next'.
1481         * src/LR0.c (first_reduction, last_reduction): Remove.
1482         (save_reductions): Don't link the new reductions, store them in
1483         this_state.
1484         * src/lalr.c (set_state_table): No need to attach reductions to
1485         states, it's already done.
1486         * src/output.c (output_actions): No longer free the shifts, then
1487         the reductions, then the states: free all the states and their
1488         members.
1489
1490 2001-12-10  Akim Demaille  <akim@epita.fr>
1491
1492         * src/options.c (OPTN, DRTV, BOTH): New.
1493         (option_table): Use them.
1494
1495         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1496         the job of system.h.
1497         * src/options.c: Don't include stdio.h and xalloc.h for the same
1498         reasons.
1499
1500 2001-12-10  Akim Demaille  <akim@epita.fr>
1501
1502         * src/output.c (output, prepare): Make sure the values of the
1503         muscles `action' and `prologue' are 0-terminated.
1504
1505 2001-12-10  Akim Demaille  <akim@epita.fr>
1506
1507         Clean up GCC warnings.
1508
1509         * src/reader.c (copy_action): `buf' is not used.
1510         (parse_skel_decl): Be static.
1511         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1512         * src/options.h (create_long_option_table): Have a real prototype.
1513         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1514         (hash_delete_at): Return const void *.
1515         Adjust casts to preserve the const.
1516
1517 2001-12-10  Akim Demaille  <akim@epita.fr>
1518
1519         * configure.in: Require 2.52g.
1520         M4 is not needed, but AUTOM4TE is.
1521         * m4/m4.m4: Remove.
1522         * tests/Makefile.am: Adjust.
1523
1524 2001-12-10  Akim Demaille  <akim@epita.fr>
1525
1526         One structure for states is enough, even though theoretically
1527         there are LR(0) states and LALR(1) states.
1528
1529         * src/lalr.h (state_t): Remove.
1530         (state_table): Be state_t **, not state_t *.
1531         * src/state.h (core, CORE_ALLOC): Rename as...
1532         (state_t, STATE_ALLOC): this.
1533         Add the LALR(1) members: shifts, reductions, errs.
1534         * src/LR0.c (state_table): Rename as...
1535         (state_hash): this, to avoid name clashes with the global
1536         `state_table'.
1537         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1538         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

1541
1542         Bison dumps core on bash.y.
1543         Reported by Pascal Bart.
1544
1545         * src/warshall.c (bitmatrix_print): New.
1546         (TC): Use it.
1547         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1548         j must be the outer loop.
1549         * tests/regression.at (Broken Closure): New.
1550
1551 2001-12-05  Akim Demaille  <akim@epita.fr>
1552
1553         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1554         its argument.
1555         Reported by Peter Hámorský.
1556
1557 2001-12-05  Akim Demaille  <akim@epita.fr>
1558
1559         * src/conflicts.c (err_table): Remove.
1560         (resolve_sr_conflict): Adjust.
1561         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1562         Rename as...
1563         (state_t.reductions, state_t.shifts): this.
1564
1565 2001-12-05  Akim Demaille  <akim@epita.fr>
1566
1567         * src/reduce.c (reduce_grammar_tables): No longer disable the
1568         removal of useless rules via CPP but via `if (0)', so that the
1569         compiler still check the code is valid.
1570         For instance, it should have noticed `rline' no longer exists: use
1571         the `line' member of rule_t.
1572         * src/gram.c (dummy, rline): Remove, unused.
1573
1574 2001-12-05  Akim Demaille  <akim@epita.fr>
1575
1576         * src/output.c (pack_vector): Use assert, not berror.
1577         * src/main.c (berror): Remove, unused.
1578
1579 2001-12-05  Akim Demaille  <akim@epita.fr>
1580
1581         New experimental feature: if --verbose --trace output all the
1582         items of a state, not only its kernel.
1583
1584         * src/print.c (print_core): If `trace_flag', then invoke closure
1585         before outputting the items of the state (print_core is no longer
1586         a correct name them).
1587         (print_results): Invoke new_closure/free_closure if needed.
1588
1589 2001-12-05  Akim Demaille  <akim@epita.fr>
1590
1591         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1592         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1593         (nitemset): for consistency with the rest of the project.
1594
1595 2001-12-05  Akim Demaille  <akim@epita.fr>
1596
1597         * src/closure.c (print_closure): Improve.
1598         (closure): Use it for printing input and output.
1599
1600 2001-12-05  Akim Demaille  <akim@epita.fr>
1601
1602         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1603         indexed by nonterminals.
1604
1605 2001-12-05  Akim Demaille  <akim@epita.fr>
1606
1607         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1608         what it was!).
1609         * src/warshall.h: Remove accidental duplication of the content.
1610
1611 2001-12-05  Akim Demaille  <akim@epita.fr>
1612
1613         * src/closure.c (set_fderives): De-obfuscate.
1614
1615 2001-12-05  Akim Demaille  <akim@epita.fr>

1620
1621         * src/closure.c (set_firsts): De-obfuscate.
1622
1623 2001-12-05  Akim Demaille  <akim@epita.fr>
1624
1625         * src/output.c (action_row): De-obfuscate
1626         using the good o' techniques: arrays not pointers, variable
1627         locality, BITISSET, RESETBIT etc.
1628
1629 2001-12-05  Akim Demaille  <akim@epita.fr>
1630
1631         Pessimize the code to simplify it: from now on, all the states
1632         have a valid SHIFTS, which NSHIFTS is possibly 0.
1633
1634         * src/LR0.c (shifts_new): Be global and move to..
1635         * src/state.c, src/state.h: here.
1636         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1637         * src/print_graph: Adjust.
1638
1639 2001-12-05  Akim Demaille  <akim@epita.fr>
1640
1641         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1642         * src/conflicts.c: Use it.
1643         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1644         incorrectly ``simplified''.
1645
1646 2001-12-05  Akim Demaille  <akim@epita.fr>
1647
1648         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1649         using the good o' techniques: arrays not pointers, variable
1650         locality, BITISSET, RESETBIT etc.
1651
1652 2001-12-05  Akim Demaille  <akim@epita.fr>
1653
1654         * src/state.h (SHIFT_SYMBOL): New.
1655         * src/conflicts.c: Use it to deobfuscate.
1656
1657 2001-12-05  Akim Demaille  <akim@epita.fr>
1658
1659         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1660         (print_reductions): De-obfuscate using the good o' techniques:
1661         arrays not pointers, variable locality, BITISSET.
1662
1663 2001-12-05  Akim Demaille  <akim@epita.fr>
1664
1665         * src/conflicts.c (print_reductions): Arrays, not pointers.
1666         Use BITISSET.
1667
1668 2001-12-05  Akim Demaille  <akim@epita.fr>
1669
1670         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1671
1672 2001-12-05  Akim Demaille  <akim@epita.fr>
1673
1674         * src/conflicts.c (print_reductions): Improve variable locality.
1675
1676 2001-12-05  Akim Demaille  <akim@epita.fr>
1677
1678         * src/conflicts.c (print_reductions): Pessimize, but clarify.

1683
1684 2001-12-05  Akim Demaille  <akim@epita.fr>
1685
1686         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
1687         * src/lalr.c: Use them.
1688
1689 2001-12-05  Akim Demaille  <akim@epita.fr>
1690
1691         * src/LR0.c (augment_automaton): Formatting changes.
1692         Better variable locality.
1693
1694 2001-12-05  Akim Demaille  <akim@epita.fr>
1695
1696         * src/lalr.c (matrix_print): New.
1697         (transpose): Use it.
1698         Use arrays instead of pointers.
1699
1700 2001-12-05  Akim Demaille  <akim@epita.fr>
1701
1702         * src/lalr.c (maxrhs): Move to...
1703         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1704         * src/lalr.c (build_relations): Adjust.
1705
1706 2001-12-05  Akim Demaille  <akim@epita.fr>
1707
1708         * src/lalr.c (transpose): Free the memory allocated to the
1709         argument, as it is replaced by the results by the unique caller.
1710         (build_relations): Merely invoke transpose: it handles the memory
1711         deallocation.
1712         Improve variable locality.
1713         Avoid variables used as mere abbreviations.
1714         (compute_lookaheads): Use arrays instead of pointers.
1715
1716 2001-12-05  Akim Demaille  <akim@epita.fr>
1717
1718         * src/lalr.c (initialize_F): Improve variable locality.
1719         Avoid variables used as mere abbreviations.
1720
1721 2001-12-05  Akim Demaille  <akim@epita.fr>
1722
1723         * src/derives.c (print_derives): Display the ruleno.
1724         * src/lalr.c (initialize_F, transpose): Better variable locality
1725         to improve readability.
1726         Avoid variables used as mere abbreviations.
1727
1728 2001-12-05  Akim Demaille  <akim@epita.fr>
1729
1730         * src/lalr.c (traverse): Use arrays instead of pointers.
1731
1732 2001-12-05  Akim Demaille  <akim@epita.fr>
1733
1734         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1735         the handling of squeue.
1736         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1737
1738 2001-12-05  Akim Demaille  <akim@epita.fr>
1739
1740         Because useless nonterminals are now kept alive (instead of being
1741         `destroyed'), we now sometimes examine them, and store information
1742         related to them.  Hence we need to know their number, and adjust
1743         memory allocations.
1744
1745         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1746         static.
1747         * src/LR0.c (allocate_itemsets): The memory allocated to
1748         `symbol_count' was used for two different purpose: once to count
1749         the number of occurrences of each symbol, and later reassigned to
1750         `shift_symbol', containing the symbol that can be shifted from a
1751         given state.
1752         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1753         only, and...
1754         (new_itemsets): Allocate `shift_symbol' here.
1755         (allocate_itemsets): symbol_count includes useless nonterminals.
1756         Make room for them.
1757         (free_storage): Use `free', not `XFREE', for pointers that cannot
1758         be null.
1759
1760 2001-12-05  Akim Demaille  <akim@epita.fr>
1761
1762         * src/nullable.c (set_nullable): Deobfuscate the handling of
1763         ritem.
1764         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1765
1766 2001-12-05  Akim Demaille  <akim@epita.fr>
1767
1768         * src/gram.c, src/gram.h (ritem_print): New.
1769         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1770         (This useless function was defined only to work around VMS linkers
1771         that can't handle compilation units with variables only).
1772         * src/reduce.c (dump_grammar): Use it to trace the construction of
1773         ritem.
1774
1775 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1776
1777         * src/bison.simple (union yyalloc): Change member names
1778         to be the same as the stack names.
1779         (yyparse): yyptr is now union yyalloc *, not char *.
1780         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1781         and may generate better code on some machines.
1782         (yystpcpy): Use prototype if __STDC__ is defined, not just
1783         if __cplusplus is defined.
1784
1785 2001-11-30  Akim Demaille  <akim@epita.fr>
1786
1787         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1788         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1789         Gettext doesn't compile cleanly, and dies with -Werror.
1790         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1791         Include WARNING_CFLAGS here.
1792         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1793         before being defined.
1794
1795 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1796
1797         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1798         First arg is int, not unsigned.
1799         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1800         (SIZE_MAX, UINT_MAX): New macros.
1801         (quotearg_n_options): Abort if N is negative.
1802         Avoid overflow check on hosts where size_t is 64 bits and int
1803         is 32 bits, as overflow is impossible there.
1804         Fix off-by-one typo that caused unnecessary reallocation.
1805
1806 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1807
1808         Name space cleanup in generated parser.
1809
1810         * doc/bison.texinfo (Bison Parser): Discuss system headers
1811         and their effect on the user name space.

1814         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1815         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1816         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1817
1818         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1819         on user names when possible.
1820
1821         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.

1898         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1899         an arbitrary restriction on hosts where size_t is wider than int.
1900
1901         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1902         a parser stack overflow.  Allocate just one block of memory for all
1903         three stacks, instead of allocating three blocks; this typically is
1904         faster and reduces fragmentation.
1905
1906         Do not limit the number of items in the stack to a value that fits
1907         in 'int', as this is an arbitrary limit on hosts with 64-bit
1908         size_t and 32-bit int.

1969
1970         * src/closure.c (closure): No longer optimize the special case

2206         * src/derives.c: Likewise.
2207         * src/reduce.c: (inaccessable_symbols): Using if is better style

2236
2237         * src/vcg.c: You do the output, so you are responsible of the
2238         handling of VCG syntax, in particular: use quotearg.

2240         (print_actions): Don't output the actions as part of the nodes,

2335         * tests/calc.at, tests/output.at, tests/regression.at,
2336         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
2337         now the tests are run in private dirs, therefore AC_CLEANUP and
2338         family can be simplified to 0-ary.
2339         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
2340         use abs. path to find config.h.
2341         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
2342         stderr, there can be way too much random noise.

2360         * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
2361         Revert a previous patch:  these are really const.

2365         arg_offset.
2366         arg is const.

2368         token_buffer not to change.

2377 2001-11-12  Akim Demaille  <akim@epita.fr>
2378
2379         * src/system.h (ngettext): Now that we use ngettext, be sure to

2464         * src/reader.c (parse_union_decl): Output yystype/YYSTYPE as we do
2465         with yyltype/YYLTYPE.  This allows inclusion of the generated

3287
3288         * src/bison.simple (yyparse): Don't take the address of an

3298         completely wrong.

3337         bound to true.
3338         (read_declarations): Add case for macro definition.
3339         (copy_identifier): New.
3340         (parse_macro_decl): Read macro identifiers using copy_identifier

3375         with something new. Skeletons are now processed character by character
3376         rather than line by line, and Bison looks for '%%' macros. This is the
3377         first step in making Bison's output process (a lot) more flexible.
3378         (output_parser): Use the macro table.

3706
3707         * src/reader.c (gensym): `gensym_count' is your own.
3708         Use a static buf to create the symbol name, as token_buffer is no
3709         longer a buffer.
3710
3711 2001-02-08  Akim Demaille  <akim@epita.fr>
3712
3713         * src/conflicts.c (conflict_report): Be sure not to append to res
3714         between two calls, which could happen if both first sprintf were

3720         New, from fileutils 4.0.37.
3721         * configure.in: Require Autoconf 2.49c.  I took some time before
3722         making this decision.  This is the only way out for portability
3723         issues in Bison, it would mean way too much duplicate effort to
3724         import in Bison features implemented in 2.49c since 2.13.
3725         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

3735         the obstacks.
3736
3737         * src/lex.c (token_obstack): New.
3738         (init_lex): Initialize it.  No longer call...
3739         (grow_token_buffer): this.  Remove it.
3740         Adjust all the places which used it to use the obstack.
3741

3743
3744         * src/lex.h: Rename all the tokens:
3745         s/\bENDFILE\b/tok_eof/g;
3746         s/\bIDENTIFIER\b/tok_identifier/g;
3747         etc.
3748         Let them be enums, not #define, to ease debugging.
3749         Adjust all the code.
3750
3751 2001-01-18  Akim Demaille  <akim@epita.fr>
3752
3753         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
3754         * src/lex.c (maxtoken, grow_token_buffer): Static.
3755
3756 2001-01-18  Akim Demaille  <akim@epita.fr>
3757
3758         Since we now use obstacks, more % directives can be enabled.
3759
3760         * src/lex.c (percent_table): Also accept `%yacc',
3761         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3762         `%debug'.
3763         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3764         instead of returning a token.
3765         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3766         * src/reader.c (read_declarations): Adjust.
3767         * src/files.c (open_files): Don't call `compute_base_names', don't
3768         compute `attrsfile' since they depend upon data which might be
3769         *in* the input file now.
3770         (output_files): Do it here.
3771         * src/output.c (output_headers): Document the fact that this patch
3772         introduces a guaranteed SEGV for semantic parsers.
3773         * doc/bison.texinfo: Document them.
3774         * tests/suite.at: Exercise these %options.
3775
3776 2000-12-20  Akim Demaille  <akim@epita.fr>
3777
3778         Also handle the output file (--verbose) with obstacks.
3779
3780         * files.c (foutput): Remove.
3781         (output_obstack): New.
3782         Adjust all dependencies.

3784         * src/system.h (obstack_grow_string): Rename as...
3785         (obstack_sgrow): this.  Be ready to work with non literals.

3790         * src/files.c (open_files): Fix the computation of short_base_name
3791         in the case of `-o foo.tab.c'.
3792
3793 2000-12-20  Akim Demaille  <akim@epita.fr>
3794
3795         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

3797         FILE * parameters.
3798
3799 2000-12-20  Akim Demaille  <akim@epita.fr>
3800
3801         * src/files.c (open_files): Actually the `.output' file is based
3802         on the short_base_name, not base_name.
3803         * tests/suite.at (Checking output file names): Adjust.
3804
3805 2000-12-20  Akim Demaille  <akim@epita.fr>
3806
3807         * src/bison.s1: Remove, we now use directly...
3808         * src/bison.simple: this.
3809         * src/Makefile.am: Use pkgdata instead of data.
3810

3824         (output_files): Adjust.
3825         (base_name, short_base_name): Be global.
3826         Adjust dependencies.
3827
3828 2000-12-19  Akim Demaille  <akim@epita.fr>
3829
3830         * src/files.c (strsuffix): New.
3831         (stringappend): Be just like strcat but allocate.
3832         (base_names): Eve out from open_files.
3833         Try to simplify the rather hairy computation of base_name and
3834         short_base_name.
3835         (open_files): Use it.
3836         * tests/suite.at (Checking output file names): New test.

3845         * src/bison.hairy: Likewise.
3846
3847 2000-12-19  Akim Demaille  <akim@epita.fr>
3848
3849         * src/output.c (output_parser): Compute the `#line' lines when
3850         there are.
3851         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
3852         Suggested by Hans Aberg.
3853
3854 2000-12-19  Akim Demaille  <akim@epita.fr>
3855
3856         Let the handling of the skeleton files be local to the procedures
3857         that use it.
3858
3859         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No

3874 2000-12-19  Akim Demaille  <akim@epita.fr>
3875
3876         * src/files.c (open_files): Yipee!  We no longer need all the code
3877         looking for `/tmp' since we have no tmp file.
3878
3879 2000-12-19  Akim Demaille  <akim@epita.fr>
3880
3881         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

3894
3895         * src/reader.c (copy_definition, parse_union_decl, copy_action)
3896         (copy_guard): Quote the file names.
3897         Reported by Laurent Mascherpa.

3907
3908         * lib/obstack.h: Formatting changes.
3909         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3910         prevents type checking.
3911         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3912         cast the value to (void *): assigning a `foo *' to a `void *'
3913         variable is valid.
3914         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3915         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

4102         When a literal string is used to define two different tokens,
4103         `bison -v' segfaults.
4104         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
4105
4106         * tests/regression.m4: New file.
4107         Include the core of the sample provided by Piotr Gackiewicz.

4109         properly.

4112
4113         * src/reader.c (parse_expect_decl): Keep `count' within the size
4114         of `buffer'.
4115         From Neil Booth.
4116
4117 2000-10-02  Paul Eggert  <eggert@twinsun.com>
4118
4119         * bison.s1 (yyparse): Assign the default value
4120         unconditionally, to avoid a GCC warning and make the parser a
4121         tad smaller.
4122
4123 2000-10-02  Akim Demaille  <akim@epita.fr>
4124
4125         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
4126         options.

4128 2000-10-02  Akim Demaille  <akim@epita.fr>
4129
4130         * src/derives.c, src/print.c, src/reduce.c: To ease the
4131         translation, move some `\n' out of the translated strings.
4132
4133 2000-10-02  Akim Demaille  <akim@epita.fr>
4134
4135         The location tracking mechanism is precious for parse error
4136         messages.  Nevertheless, it is enabled only when `@n' is used in
4137         the grammar, which is a different issue (you can use it in error
4138         message, but not in the grammar per se).  Therefore, there should
4139         be another means to enable it.
4140
4141         * src/getargs.c (getargs): Support `--locations'.
4142         (usage): Report it.
4143         * src/getargs.h (locationsflag): Export it.
4144         * src/lex.c (percent_table): Support `%locations'.
4145         * src/reader.c (yylsp_needed): Remove this variable, now replaced
4146         with `locationsflag'.
4147         * doc/bison.texinfo: Document `--locations' and `%locations'.
4148         Sort the options.
4149         * tests/calc.m4: Test it.
4150
4151         For regularity of the names, replace each
4152         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4153         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4154         In addition replace each `flag' with `_flag'.
4155
4156 2000-10-02  Akim Demaille  <akim@epita.fr>
4157
4158         Also test parse error messages, including with YYERROR_VERBOSE.
4159
4160         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4161         associative).
4162         Use it to check the computations.
4163         Use it to check `nonassoc' is honored.
4164         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4165         `--yyerror-verbose'.
4166         (_AT_CHECK_CALC): Adjust to this option.
4167         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4168
4169 2000-10-02  Akim Demaille  <akim@epita.fr>
4170
4171         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
4172         the latter demonstrates a flaw in the handling of non debugging
4173         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4174         was used in order to simplify:
4175
4176         #if YYDEBUG
4177         if (yydebug)
4178         {
4179         ...
4180         }
4181         #endif
4182
4183         into
4184
4185         if (yydebug)
4186         {
4187         ...
4188         }
4189
4190         unfortunately this leads to a CPP conflict when
4191         `--name-prefix=foo' is used since it produces `#define yydebug
4192         foodebug'.
4193
4194         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4195         (YYDPRINTF): New macro.
4196         Spread its use.
4197         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4198         the bison options.
4199         Also test `--verbose', `--defines' and `--name-prefix'.
4200
4201 2000-10-02  Akim Demaille  <akim@epita.fr>
4202
4203         Improve the readability of the produced parsers.
4204
4205         * src/bison.s1: Formatting changes.
4206         Improve the comment related to the `$' mark.
4207         (yydefault): Don't fall through to `yyresume': `goto' there.
4208         * src/output.c (output_parser): When the `$' is met, skip the end
4209         of its line.
4210         New variable, `number_of_dollar_signs', to check there's exactly
4211         one `$' in the parser skeleton.
4212
4213 2000-10-02  Akim Demaille  <akim@epita.fr>
4214
4215         * lib/xstrdup.c: New file, from the fileutils.
4216         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4217         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4218         instead of strlen + xmalloc + strcpy.
4219         * src/symtab.c (copys): Remove, use xstrdup instead.
4220
4221 2000-10-02  Akim Demaille  <akim@epita.fr>
4222
4223         * src/gram.h (associativity): New enum type which replaces the
4224         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4225         `right_assoc', `left_assoc' and `non_assoc'.
4226         Adjust all dependencies.
4227         * src/reader.c: Formatting changes.
4228         (LTYPESTR): Don't define it, use it as a literal in
4229         `reader_output_yylsp'.
4230         * src/symtab.h (symbol_class): New enum type which replaces the
4231         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4232         `sunknown', `stoken and `snterm'.
4233
4234 2000-10-02  Akim Demaille  <akim@epita.fr>
4235
4236         * src/getargs.c (fixed_outfiles): Rename as...
4237         (yaccflag): for consistency and accuracy.
4238         Adjust dependencies.
4239
4240 2000-10-02  Akim Demaille  <akim@epita.fr>
4241
4242         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4243         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4244         difficult and introduced a lot of core dump.  It turns out that
4245         Bison used an implementation of `xmalloc' based on `calloc', and
4246         at various places it does depend upon the initialization to 0.  I
4247         have not tried to isolate the pertinent places, and all the former
4248         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4249         someone should address this issue.
4250
4251         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4252         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
4253         files.
4254         Adjust dependencies.

4263
4264 2000-10-02  Akim Demaille  <akim@epita.fr>
4265
4266         * src/state.h (nstates, final_state, first_state, first_shift)
4267         (first_reduction): Move their exportation from here...
4268         * src/LR0.h: to here.
4269         Adjust dependencies.
4270         * src/getargs.c (statisticsflag): New variable.
4271         Add support for `--statistics'.

4273
4274         Remove a lot of now useless `extern' statements in most files.

4307         * src/reduce.h: New file.
4308         Propagate its inclusion.
4309         * src/reduce.c: Topological sort and other formatting changes.
4310         (bool, TRUE, FALSE): Move their definition to...
4311         * src/system.h: here.
4312
4313 2000-10-02  Akim Demaille  <akim@epita.fr>
4314
4315         * src/files.c: Formatting changes.
4316         (tryopen, tryclose, openfiles): Rename as...
4317         (xfopen, xfclose, open_files): this.
4318         (stringappend): static.
4319         * src/files.h: Complete the list of exported symbols.
4320         Propagate its use.
4321
4322 2000-10-02  Akim Demaille  <akim@epita.fr>
4323
4324         * src/reader.h: New file.
4325         Propagate its use instead of tedious list of `extern' and
4326         prototypes.
4327         * src/reader.c: Formatting changes, topological sort,
4328         s/register//.
4329
4330 2000-10-02  Akim Demaille  <akim@epita.fr>
4331

4339
4340         * src/lalr.h: New file.

4344 2000-10-02  Akim Demaille  <akim@epita.fr>
4345
4346         * src/output.c (token_actions): Introduce a temporary array,
4347         YYDEFACT, that makes it possible for this function to use
4348         output_short_table.
4349
4350 2000-10-02  Akim Demaille  <akim@epita.fr>
4351
4352         `user_toknums' is output as a `short[]' in `output.c', while it is
4353         defined as a `int[]' in `reader.c'.  For consistency with the
4354         other output tables, `user_toknums' is now defined as a table of
4355         shorts.
4356
4357         * src/reader.c (user_toknums): Be a short table instead of an int
4358         table.
4359         Adjust dependencies.
4360
4361         Factor the short table outputs.
4362
4363         * src/output.c (output_short_table): New function.

4367 2000-10-02  Akim Demaille  <akim@epita.fr>
4368
4369         * src/output.c (output): Topological sort of the functions, in
4370         order to get rid of the `static' prototypes.
4371         No longer use `register'.
4372         * src/output.h: New file.
4373         Propagate its inclusion in files explicitly prototyping functions
4374         from output.c.

4386         (new_closure, free_closure): these.  Adjust dependencies.
4387         * src/LR0.c: Formatting changes, topological sort, use of
4388         cloture.h.

4396         inclusion.
4397         Don't define PARAMS.
4398         * src/system.h: Define PARAMS.
4399         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
4400         purpose of config.h.  system.h must not try to fix wrong
4401         definitions in config.h.
4402
4403 2000-09-20  Akim Demaille  <akim@epita.fr>

4415         Use these macros to test bison with options `', `--raw',
4416         `--debug', `--yacc', `--yacc --debug'.
4417
4418 2000-09-19  Akim Demaille  <akim@epita.fr>
4419
4420         * src/output.c: Formatting changes.

4479         (VERSION_STRING): Remove.
4480
4481 2000-04-14  Akim Demaille  <akim@epita.fr>
4482
4483         * src/reader.c (copy_comment2): New function, same as former

4527         complain.c::complain.
4528         (toomany): Remove, use fatal instead.

4538         * configure.in: Adjust.
4539         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's
4540         useless.

4561
4562         * src/Makefile.am (bison.simple): Fix the awk program: quote only
4563         the file name, not the whole `#line LINE FILE'.
4564
4565 2000-03-17  Akim Demaille  <akim@epita.fr>
4566
4567         On syntax errors, report the token on which we choked.
4568
4569         * src/bison.s1 (yyparse): In the label yyerrlab, when

4587
4588         * src/reader.c (copy_definition): Use copy_string and
4589         copy_comment.  Removed now unused `match', `ended',
4590         `cplus_comment'.
4591         (copy_comment, copy_string): Moved, to be visible from
4592         copy_definition.
4593
4594 2000-03-17  Akim Demaille  <akim@epita.fr>
4595
4596         * src/reader.c (copy_string): Declare `static inline'.  No
4597         problems with inline, since it is checked by configure.

4617 2000-03-17  Akim Demaille  <akim@epita.fr>
4618
4619         Change the handling of @s so that they behave exactly like $s.
4620         There is now a pseudo variable @$ (readble and writable), location
4621         of the lhs of the rule (by default ranging from the location of
4622         the first symbol of the rhs, to the location of the last symbol,
4623         or, if the rhs is empty, YYLLOC).
4624
4625         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4626         yyval.
4627         (yyparse): When providing a default semantic action, provide a
4628         default location action.
4629         (after the $): No longer change `*YYLSP', just stack YYLOC the
4630         same way you stack YYVAL.
4631         * src/reader.c (read_declarations): Use warns.
4632         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4633         (copy_action, case '@'): Likewise.
4634         Use a standard error message, to save useless work from
4635         translators.
4636
4637 2000-03-17  Akim Demaille  <akim@epita.fr>
4638
4639         * src/bison.s1: Formatting and cosmetics changes.

4643 2000-03-17  Akim Demaille  <akim@epita.fr>
4644
4645         * src/bison.s1 (#line): All set to `#line' only, since the
4646         Makefile now handles them.
4647
4648 2000-03-16  Akim Demaille  <akim@epita.fr>
4649
4650         * src/output.c (output_rule_data): Output the documentation of

4652         (Copyright notice): Update.
4653         Formatting changes.
4654
4655 2000-03-16  Akim Demaille  <akim@epita.fr>
4656
4657         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4658         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4659         One `#if YYDEBUG' remains, since it uses variables which are
4660         defined only if `YYDEBUG != 0'.
4661
4662 2000-03-16  Akim Demaille  <akim@epita.fr>
4663
4664         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
4665         and related variables so that the similarities are highlighted.
