 154 2002-02-14  Paul Eggert  <eggert@twinsun.com>
 155
 156         Remove the support for C++ namespace cleanliness; it was
 157         causing more problems than it was curing, since it didn't work
 158         properly on some nonstandard C++ compilers.  This can wait
 159         for a proper C++ parser.
 160
 161         * NEWS: Document this.
 162         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention

 170

 177 2002-02-13  Andreas Schwab  <schwab@suse.de>
 178
 179         * src/output.c (output_rule_data): Don't output NULL, it might
 180         not be defined yet.

 200
 201 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 202
 203         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
 204         more consistent when naming methods and variables.  Put preprocessor
 205         directives around tables only needed for debugging.
 206
 207 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 208
 209         * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in

 227 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
 228
 229         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
 230         not expanded by m4.
 231
 232 2002-02-05  Akim Demaille  <akim@epita.fr>
 233
 234         * data/bison.c++: Adjust to the M4 back end.
 235         More is certainly needed.

 243         BISON_HAIRY.
 244         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
 245         specific values.  Now it is m4 that performs the lookup.
 246         * src/parse-skel.y: Remove.
 247         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
 248         * src/output.c (actions_output, guards_output)
 249         (token_definitions_output): No longer keeps track of the output
 250         line number, hence remove the second argument.
 251         (guards_output): Check against the guard member of a rule, not the
 252         action member.
 253         Adjust callers.
 254         (output_skeleton): Don't look for the skeleton location, let m4 do
 255         that.
 256         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
 257         file will be used.
 258         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
 259         (prepare): Given that for the time being changesyntax is not
 260         usable in M4, rename the muscles using `-' to `_'.
 261         Define `defines_flag', `output_parser_name' and `output_header_name'.
 262         * src/output.h (actions_output, guards_output)
 263         (token_definitions_output): Adjust prototypes.
 264         * src/scan-skel.l: Instead of scanning the skeletons, it now

 266         * data/bison.simple: Adjust to be used by M4(sugar).
 267         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
 268         to date.
 269         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
 270         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
 271         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
 272         shamelessly stolen from CVS Autoconf.
 273

 286

 288         * data/: here.
 289
 290 2002-01-29  Paul Eggert  <eggert@twinsun.com>
 291
 292         * src/bison.simple (YYSIZE_T): Do not define merely because
 293         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 294         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 295
 296 2002-01-27  Akim Demaille  <akim@epita.fr>
 297
 298         Fix `%nonassoc and eof'.
 299
 300         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
 301         which were not properly copied!  Replace
 302         memcpy (res->errs, src->errs, src->nerrs);
 303         with
 304         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
 305         !!!
 306         * tests/regression.at (%nonassoc and eof): Adjust to newest
 307         Autotest: `.' is not in the PATH.

 318         * tests/torture.at: Adjust to the newest Autotest which no longer
 319         forces `.' in the PATH.

 365

 367

 369         canonical definition.

 378 2002-01-09  Akim Demaille  <akim@epita.fr>
 379
 380         * src/files.c, src/files.h (output_infix): New.
 381         (tab_extension): Remove.
 382         (compute_base_names): Compute the former, drop the latter.
 383         * src/output.c (prepare): Insert the muscles `output-infix', and
 384         `output-suffix'.
 385         * src/parse-skel.y (string, string.1): New.
 386         (section.header): Use it.
 387         (section.yacc): Remove.
 388         (prefix): Remove too.
 389         * src/scan-skel.l: Adjust.
 390         * src/bison.simple, src/bison.hairy: Adjust.
 391
 392 2002-01-09  Akim Demaille  <akim@epita.fr>
 393
 394         * configure.in (WERROR_CFLAGS): Compute it.
 395         * src/Makefile.am (CFLAGS): Pass it.
 396         * tests/atlocal.in (CFLAGS): Idem.
 397         * src/files.c: Fix a few warnings.
 398         (get_extension_index): Remove, unused.
 399
 400 2002-01-08  Akim Demaille  <akim@epita.fr>
 401
 402         * src/getargs.c (AS_FILE_NAME): New.
 403         (getargs): Use it to convert DOSish file names.
 404         * src/files.c (base_name): Rename as full_base_name to avoid
 405         clashes with `base_name ()'.
 406         (filename_split): New.
 407         (compute_base_names): N-th rewrite, using filename_split.
 408
 409 2002-01-08  Akim Demaille  <akim@epita.fr>
 410
 411         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
 412         New, stolen from the Fileutils 4.1.
 413         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
 414         * configure.in: Check for the presence of memrchr, and of its
 415         prototype.
 416
 417 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
 418
 419         * lib/hash.h (__P): Added definition for this macro.
 420         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
 421         BUILT_SOURCES, to ensure they are generated first.
 422         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
 423         %error-verbose to allow bootstrapping with bison 1.30x.
 424
 425 2002-01-06  Akim Demaille  <akim@epita.fr>
 426
 427         * src/reader.c (parse_braces): Don't fetch the next char, the
 428         convention is to fetch on entry.
 429         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
 430         'switch' without a following semicolon.
 431         * tests/regression.at (braces parsing): New.
 432
 433 2002-01-06  Akim Demaille  <akim@epita.fr>
 434
 435         Bison is dead wrong in its RR conflict reports.
 436
 437         * tests/torture.at (GNU Cim Grammar): New.
 438         * src/conflicts.c (count_rr_conflicts): Fix.
 439
 440 2002-01-06  Akim Demaille  <akim@epita.fr>
 441
 442         Creating package.m4 from configure.ac causes too many problems.
 443
 444         * tests/Makefile.am (package.m4): Create it by hand,
 445         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
 446
 447 2002-01-06  Akim Demaille  <akim@epita.fr>
 448
 449         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
 450         skeleton.h.
 451
 452 2002-01-04  Paul Eggert  <eggert@twinsun.com>
 453
 454         * doc/bison.texinfo (Debugging):
 455         Remove YYSTDERR; it's no longer defined or used.
 456         Also, s/cstdio.h/cstdio/.
 457
 458 2002-01-03  Akim Demaille  <akim@epita.fr>
 459
 460         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
 461
 462 2002-01-03  Akim Demaille  <akim@epita.fr>
 463
 464         * src/parse-skel.y (process_skeleton): Don't bind the parser's
 465         tracing code to --trace, wait for a better --trace option, with
 466         args.
 467
 468 2002-01-03  Akim Demaille  <akim@epita.fr>
 469
 470         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
 471         The ISO C++ standard is extremely clear about it: stderr is
 472         considered a macro, not a regular symbol (see table 94 `Header
 473         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
 474         Therefore std:: does not apply to it.  It still does with fprintf.
 475         Also, s/cstdio.h/cstdio/.
 476
 477 2002-01-03  Akim Demaille  <akim@epita.fr>
 478
 479         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
 480         for non system headers.
 481
 482 2002-01-02  Akim Demaille  <akim@epita.fr>
 483
 484         Equip the skeleton chain with location tracking, runtime trace,
 485         pure parser and scanner.
 486
 487         * src/parse-skel.y: Request a pure parser, locations, and prefix
 488         renaming.
 489         (%union): Having several members with the same type does not help
 490         type mismatches, simplify.
 491         (YYPRINT, yyprint): New.
 492         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
 493         (skel_error): this.
 494         Handle locations.
 495         * src/scan-skel.l: Adjust to these changes.
 496         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
 497         (LOCATION_PRINT, skel_control_t): New.
 498
 499 2001-12-30  Akim Demaille  <akim@epita.fr>
 500
 501         * src/parse-skel.y: Get rid of the shift/reduce conflict:
 502         replace `gb' with BLANKS.
 503         * src/scan-skel.l: Adjust.
 504
 505 2001-12-30  Akim Demaille  <akim@epita.fr>
 506
 507         * src/system.h: We don't need nor want bcopy.
 508         Throw away MS-DOS crap: we don't need getpid.
 509         * configure.in: We don't need strndup.  It was even causing
 510         problems: because Flex includes the headers *before* us,
 511         _GNU_SOURCE is not defined by config.h, and therefore strndup was
 512         not visible.
 513         * lib/xstrndup.c: New.
 514         * src/scan-skel.l: Use it.
 515         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
 516         * src/parse-skel.y: Use %directives instead of #defines.
 517
 518 2001-12-30  Akim Demaille  <akim@epita.fr>
 519
 520         * src/skeleton.h: New.
 521         * src/output.c (output_parser, output_master_parser): Remove, dead
 522         code.
 523         * src/output.h (get_lines_number, actions_output, guards_output)
 524         (token_definitions_output): Prototype them.
 525         * src/parse-skel.y: Add the license notice.
 526         Include output.h and skeleton.h.
 527         (process_skeleton): Returns void, and takes a single parameter.
 528         * src/scan-skel.l: Add the license notice.
 529         Include skeleton.h.
 530         Don't use %option yylineno: it seems that then Flex imagines
 531         REJECT has been used, and therefore it won't reallocate its
 532         buffers (which makes no other sense to me than a bug).  It results
 533         in warnings for `unused: yy_flex_realloc'.
 534
 535 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
 536
 537         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 538         (MUSCLE_INSERT_PREFIX): ...to there.
 539         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 540         (MUSCLE_INSERT_PREFIX): Move from here...
 541
 542         * src/bison.hairy: Add a section directive.  Put braces around muscle
 543         names.  This parser skeleton is still broken, but Bison should not
 544         choke on a bad muscle 'syntax'.
 545         * src/bison.simple: Add a section directive.  Put braces around muscle
 546         names.
 547
 548         * src/files.h (strsuffix, stringappend): Add declarations.
 549         (tab_extension): Add declaration.
 550         (short_base_name): Add declaration.
 551
 552         * src/files.c (strsuffix, stringappend): No longer static.  These
 553         functions are used in the skeleton parser.
 554         (tab_extension): New.
 555         (compute_base_names): Use the computations done in this function
 556         to guess if the generated parsers should have '.tab' in their
 557         names.
 558         (short_base_name): No longer static.
 559
 560         * src/output.c (output_skeleton): New.
 561         (output): Disable call to output_master_parser, and give a try to
 562         a new skeleton handling system.
 563         (guards_output, actions_output): No longer static.
 564         (token_definitions_output, get_lines_number): No longer static.
 565
 566         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
 567
 568         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
 569         parse-skel.y.
 570
 571         * src/parse-skel.y: New file.
 572         * src/scan-skel.l: New file.
 573
 574 2001-12-29  Akim Demaille  <akim@epita.fr>
 575
 576         %name-prefix is broken.
 577
 578         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
 579         Adjust all dependencies.
 580         * tests/headers.at (export YYLTYPE): Strengthen this test: use
 581         %name-prefix.
 582
 583         Renaming yylval but not yylloc is not consistent.  Now we do.
 584
 585         * src/bison.simple: Prefix yylloc if used.
 586         * doc/bison.texinfo (Decl Summary): Document that.
 587
 588 2001-12-29  Akim Demaille  <akim@epita.fr>
 589
 590         * doc/bison.texinfo: Promote `%long-directive' over
 591         `%long_directive'.
 592         Remove all references to fixed-output-files, yacc is enough.
 593
 594 2001-12-29  Akim Demaille  <akim@epita.fr>
 595
 596         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
 597         user prologue.  These are defaults.
 598         * tests/actions.at (Mid-rule actions): Make sure the user can
 599         define YYDEBUG and YYERROR_VERBOSE.
 600
 601 2001-12-29  Akim Demaille  <akim@epita.fr>
 602
 603         * src/output.c (header_output): Don't forget to export YYLTYPE and
 604         yylloc.
 605         * tests/headers.at (export YYLTYPE): New, make sure it does.
 606         * tests/regression.at (%union and --defines, Invalid CPP headers):
 607         Move to...
 608         * tests/headers.at: here.
 609
 610 2001-12-29  Akim Demaille  <akim@epita.fr>
 611
 612         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
 613
 614 2001-12-29  Akim Demaille  <akim@epita.fr>
 615
 616         * tests/actions.at (Mid-rule actions): Output on a single line
 617         instead of several.
 618
 619 2001-12-29  Akim Demaille  <akim@epita.fr>
 620
 621         * doc/bison.texinfo: Formatting changes.
 622
 623 2001-12-29  Akim Demaille  <akim@epita.fr>
 624
 625         Don't store the token defs in a muscle, just be ready to output it
 626         on command.  Now possible via `symbols'.  Fixes a memory leak.
 627
 628         * src/output.c (token_definitions_output): New.
 629         (output_parser, header_output): Use it.
 630         * src/reader.c (symbols_save): Remove.
 631
 632 2001-12-29  Akim Demaille  <akim@epita.fr>
 633
 634         * src/bison.simple: Do not provide a default for YYSTYPE and
 635         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
 636         default.
 637
 638 2001-12-29  Akim Demaille  <akim@epita.fr>
 639
 640         Mid-rule actions are simply... ignored!
 641
 642         * src/reader.c (readgram): Be sure to attach mid-rule actions to
 643         the empty-rule associated to the dummy symbol, not to the host
 644         rule.
 645         * tests/actions.at (Mid-rule actions): New.
 646
 647 2001-12-29  Akim Demaille  <akim@epita.fr>
 648
 649         Memory leak.
 650
 651         * src/reader.c (reader): Free grammar.
 652
 653 2001-12-29  Akim Demaille  <akim@epita.fr>
 654
 655         Memory leak.
 656
 657         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
 658         since it allocates it for each state, although only one is needed.
 659         (allocate_storage): Do it here.
 660
 661 2001-12-29  Akim Demaille  <akim@epita.fr>
 662
 663         * src/options.h, src/options.c (create_long_option_table): Rename
 664         as...
 665         (long_option_table_new): this, with a clearer prototype.
 666         (percent_table): Remove, unused,
 667         * src/getargs.c (getargs): Adjust.
 668
 669 2001-12-29  Akim Demaille  <akim@epita.fr>
 670
 671         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
 672         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 673         as states.
 674
 675 2001-12-29  Akim Demaille  <akim@epita.fr>
 676
 677         * src/lalr.c (build_relations): Rename `states' as `states1'.
 678         Sorry, I don't understand exactly what it is, no better name...
 679
 680 2001-12-29  Akim Demaille  <akim@epita.fr>
 681
 682         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 683         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 684         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 685         as rules.
 686
 687 2001-12-29  Akim Demaille  <akim@epita.fr>
 688
 689         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 690         ago.
 691
 692 2001-12-29  Akim Demaille  <akim@epita.fr>
 693
 694         * src/reader.c, src/reader.h (user_toknums): Remove.
 695         Adjust all users to use symbols[i]->user_token_number.
 696
 697 2001-12-29  Akim Demaille  <akim@epita.fr>
 698
 699         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 700         Adjust all users to use symbols[i]->prec or ->assoc.
 701
 702 2001-12-29  Akim Demaille  <akim@epita.fr>
 703
 704         * src/reader.c, src/reader.h (tags): Remove.
 705         Adjust all users to use symbols[i]->tag.
 706
 707 2001-12-29  Akim Demaille  <akim@epita.fr>
 708
 709         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 710         and rule_table.
 711         * src/reader.c (packsymbols): Fill this table.
 712         Drop sprec.
 713         * src/conflicts.c (resolve_sr_conflict): Adjust.
 714         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 715         single table.
 716         Use symbols[i]->tag instead of tags[i].
 717
 718 2001-12-29  Akim Demaille  <akim@epita.fr>
 719
 720         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 721         In addition, put a comment in there, to replace...
 722         * tests/regression.at (%union and C comments): Remove.
 723
 724 2001-12-29  Akim Demaille  <akim@epita.fr>
 725
 726         * tests/regression.at (Web2c Actions): Blindly move the actual
 727         output as expected output.  The contents *seem* right to me, but I
 728         can't pretend reading perfectly parser tables...  Nonetheless, all
 729         the other tests pass correctly, the table look OK, even though the
 730         presence of `$axiom' is to be noted: AFAICS it is useless (but
 731         harmless).
 732
 733 2001-12-29  Akim Demaille  <akim@epita.fr>
 734
 735         * src/reader.c (readgram): Don't add the rule 0 if there were no
 736         rules read.  In other words, add it _after_ having performed
 737         grammar sanity checks.
 738         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 739
 740 2001-12-29  Akim Demaille  <akim@epita.fr>
 741
 742         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 743         visible, and some states have now a different number.
 744
 745 2001-12-29  Akim Demaille  <akim@epita.fr>
 746
 747         * src/reader.c (readgram): Bind the initial rule's lineno to that
 748         of the first rule.
 749         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 750         (Solved SR Conflicts): Adjust rule 0's line number.
 751
 752 2001-12-29  Akim Demaille  <akim@epita.fr>
 753
 754         Fix the `GAWK Grammar' failure.
 755
 756         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 757         the reductions of the first state which was mistakenly confused
 758         with the final state because precisely final_state was initialized
 759         to 0.
 760         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 761         now noticed by Bison.
 762         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 763         have a reduction on $default.
 764
 765 2001-12-29  Akim Demaille  <akim@epita.fr>
 766
 767         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 768         rule line numbers.
 769         * src/closure.c (print_closure): Likewise.
 770         * src/derives.c (print_derives): Likewise.
 771         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 772         now.
 773
 774 2001-12-29  Akim Demaille  <akim@epita.fr>
 775
 776         * src/lalr.c (lookaheads_print): New.
 777         (lalr): Call it when --trace-flag.
 778         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 779         are dumped.
 780
 781 2001-12-29  Akim Demaille  <akim@epita.fr>
 782
 783         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 784         when walking through ritem, even via rule->rhs.
 785         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 786         (useful_production, useless_nonterminals): Likewise.
 787         (reduce_grammar_tables): Likewise, plus update nritems.
 788         * src/nullable.c (set_nullable): Likewise.
 789         * src/lalr.c (build_relations): Likewise.
 790         * tests/sets.at (Nullable): Adjust.
 791         Fortunately, now, the $axiom is no longer nullable.
 792
 793 2001-12-29  Akim Demaille  <akim@epita.fr>
 794
 795         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 796         the 0-sentinel.
 797         * src/gram.c (ritem_longest_rhs): Likewise.
 798         * src/reduce.c (nonterminals_reduce): Likewise.

 803 2001-12-29  Akim Demaille  <akim@epita.fr>
 804
 805         * src/output.c: Comment changes.
 806
 807 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 808
 809         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 810         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 811         Sparc, as they were causing more porting problems than the
 812         (minor) performance improvement was worth.
 813
 814         Also, catch up with 1.31's YYSTD.
 815
 816 2001-12-27  Akim Demaille  <akim@epita.fr>
 817
 818         * src/output.c (output_gram): Rely on nritems, not the
 819         0-sentinel.  See below.
 820         Use -1 as separator, not 0.
 821         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 822         Rely on -1 as separator in yyrhs, instead of 0.
 823         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 824         twice `Now at end of input', therefore there are two lines less to
 825         expect.
 826
 827 2001-12-27  Akim Demaille  <akim@epita.fr>
 828
 829         * tests/regression.at (Unresolved SR Conflicts):
 830         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 831         below.
 832
 833 2001-12-27  Akim Demaille  <akim@epita.fr>
 834
 835         * src/LR0.c (new_state): Recognize the final state by the fact it
 836         is reached by eoftoken.
 837         (insert_start_shifting_state, insert_eof_shifting_state)
 838         (insert_accepting_state, augment_automaton): Remove, since now
 839         these states are automatically computed from the initial state.
 840         (generate_states): Adjust.
 841         * src/print.c: When reporting a rule number to the user, substract
 842         1, so that the axiom rule is rule 0, and the first user rule is 1.
 843         * src/reduce.c: Likewise.
 844         * src/print_graph.c (print_core): For the time being, just as for
 845         the report, depend upon --trace-flags to dump the full set of
 846         items.
 847         * src/reader.c (readgram): Once the grammar read, insert the rule
 848         0: `$axiom: START-SYMBOL $'.
 849         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 850         number of the states has changed (the final state is no longer
 851         necessarily the last), catch up.
 852
 853 2001-12-27  Akim Demaille  <akim@epita.fr>
 854
 855         Try to make the use of the eoftoken valid.  Given that its value
 856         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 857         is used instead of > 0 where appropriate, (ii), depend upon nritems
 858         instead of the 0-sentinel.
 859
 860         * src/gram.h, src/gram.c (nritems): New.
 861         Expected to be duplication of nitems, but for the time being...
 862         * src/reader.c (packgram): Assert nritems and nitems are equal.
 863         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 864         * src/closure.c (print_closure, print_fderives): Likewise.
 865         * src/gram.c (ritem_print): Likewise.
 866         * src/print.c (print_core, print_grammar): Likewise.
 867         * src/print_graph.c: Likewise.
 868
 869 2001-12-27  Akim Demaille  <akim@epita.fr>
 870
 871         * src/main.c (main): If there are complains after grammar
 872         reductions, then output the report anyway if requested, then die.
 873         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 874         * src/reader.c (eoftoken): New.
 875         (parse_token_decl): If the token being defined has value `0', it
 876         is the eoftoken.
 877         (packsymbols): No longer hack `tags' to insert `$' by hand.
 878         Be sure to preserve the value of the eoftoken.
 879         (reader): Make sure eoftoken is defined.
 880         Initialize nsyms to 0: now eoftoken is created just like the others.
 881         * src/print.c (print_grammar): Don't special case the eof token.
 882         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 883         lie anyway, albeit pleasant.
 884         * tests/calc.at: Exercise error messages with eoftoken.
 885         Change the grammar so that empty input is invalid.
 886         Adjust expectations.
 887         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 888
 889 2001-12-27  Akim Demaille  <akim@epita.fr>
 890
 891         * configure.in: Check the protos of strchr ans strspn.
 892         Replace strchr if needed.
 893         * src/system.h: Provide the protos of strchr, strspn and memchr if
 894         missing.
 895         * lib/strchr.c: New.
 896         * src/reader.c (symbols_save): Use strchr.
 897
 898 2001-12-27  Akim Demaille  <akim@epita.fr>
 899
 900         * src/print.c, src/print_graph.c (escape): New.
 901         Use it to quote the TAGS outputs.
 902         * src/print_graph.c (print_state): Now errors are in red, and
 903         reductions in green.
 904         Prefer high to wide: output the state number on a line of its own.
 905
 906 2001-12-27  Akim Demaille  <akim@epita.fr>
 907
 908         * src/state.h, src/state.c (reductions_new): New.
 909         * src/LR0.c (set_state_table): Let all the states have a
 910         `reductions', even if reduced to 0.
 911         (save_reductions): Adjust.
 912         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 913         * src/print.c (print_reductions, print_actions): Adjust.
 914         * src/output.c (action_row): Adjust.
 915
 916 2001-12-27  Akim Demaille  <akim@epita.fr>
 917
 918         * src/state.h, src/state.c (errs_new, errs_dup): New.
 919         * src/LR0.c (set_state_table): Let all the states have an errs,
 920         even if reduced to 0.
 921         * src/print.c (print_errs, print_reductions): Adjust.
 922         * src/output.c (output_actions, action_row): Adjust.
 923         * src/conflicts.c (resolve_sr_conflict): Adjust.
 924
 925 2001-12-27  Akim Demaille  <akim@epita.fr>
 926
 927         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 928
 929 2001-12-27  Akim Demaille  <akim@epita.fr>
 930
 931         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 932         * src/print.c: here.
 933         (lookaheadset, shiftset): New, used as additional storage by
 934         print_reductions.
 935         (print_results): Adjust.
 936         (print_shifts, print_gotos, print_errs): New, extracted from...
 937         (print_actions): here.
 938         * src/print_graph.c (print_actions): Remove dead code.
 939
 940 2001-12-27  Akim Demaille  <akim@epita.fr>
 941
 942         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 943         `$n' and `@n'.
 944
 945 2001-12-27  Akim Demaille  <akim@epita.fr>
 946
 947         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 948         (build_relations): Adjust.
 949
 950 2001-12-27  Akim Demaille  <akim@epita.fr>
 951
 952         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 953         duplication.
 954
 955 2001-12-27  Akim Demaille  <akim@epita.fr>
 956
 957         * src/reader.c (packgram): Catch nitems overflows.
 958
 959 2001-12-27  Akim Demaille  <akim@epita.fr>
 960
 961         * src/files.c, src/files.h (guard_obstack): Remove.
 962         * src/output.c (output): Adjust.
 963         * src/reader.c (parse_braces): New, factoring...
 964         (copy_action, copy_guard): these two which are renamed as...
 965         (parse_action, parse_guard): these.
 966         As a voluntary consequence, using braces around guards is now
 967         mandatory.
 968
 969 2001-12-27  Akim Demaille  <akim@epita.fr>
 970
 971         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 972         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 973         members.
 974         (symbol_list_new): Adjust.
 975         (copy_action): action_line is the first line, not the last.
 976         (copy_guard): Just as for actions, store the `action' only, not
 977         the switch/case/break flesh.
 978         Don't parse the user action that might follow the guard, let...
 979         (readgram): do it, i.e., now, there can be an action after a
 980         guard.
 981         In other words the guard is just explicitly optional.
 982         (packgram): Adjust.
 983         * src/output.c (guards_output): New.
 984         (output_parser): Call it when needed.
 985         (output): Also free the guard and attrs obstacks.
 986         * src/files.c, src/files.h (obstack_save): Remove.
 987         (output_files): Remove.
 988         As a result, if one needs the former `.act' file, using an
 989         appropriate skeleton which requires actions and guards is now
 990         required.
 991         * src/main.c (main): Adjust.
 992         * tests/semantic.at: New.
 993         * tests/regression.at: Use `input.y' as input file name.
 994         Avoid 8+3 problems by requiring input.c when the test needs the
 995         parser.
 996
 997 2001-12-27  Akim Demaille  <akim@epita.fr>
 998
 999         * src/reader.c (symbol_list_new): Be sure to initialize all the
1000         fields.
1001
1002 2001-12-27  Akim Demaille  <akim@epita.fr>
1003
1004         All the hacks using a final pseudo state are now useless.
1005
1006         * src/LR0.c (set_state_table): state_table holds exactly nstates.
1007         * src/lalr.c (nLA): New.
1008         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
1009         instead of lookaheadsp from the pseudo state (nstate + 1).
1010
1011 2001-12-27  Akim Demaille  <akim@epita.fr>
1012
1013         * src/output.c (action_row, token_actions): Use a state_t instead
1014         of a integer, and nlookaheads instead of the following state's
1015         lookaheadsp.
1016
1017 2001-12-27  Akim Demaille  <akim@epita.fr>
1018
1019         * src/conflicts.c (log_resolution, flush_shift)
1020         (resolve_sr_conflict, set_conflicts, solve_conflicts)
1021         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
1022         (conflicts_print, print_reductions): Use a state_t instead of an
1023         integer when referring to a state.
1024         As much as possible, depend upon nlookaheads, instead of the
1025         `lookaheadsp' member of the following state (since lookaheads of
1026         successive states are successive, the difference between state n + 1
1027         and n served as the number of lookaheads for state n).
1028         * src/lalr.c (add_lookback_edge): Likewise.
1029         * src/print.c (print_core, print_actions, print_state)
1030         (print_results): Likewise.
1031         * src/print_graph.c (print_core, print_actions, print_state)
1032         (print_graph): Likewise.
1033         * src/conflicts.h: Adjust.
1034
1035 2001-12-27  Akim Demaille  <akim@epita.fr>
1036
1037         * src/bison.hairy: Formatting/comment changes.
1038         ANSIfy.
1039         Remove `register' indications.
1040         Add plenty of `static'.
1041
1042 2001-12-27  Akim Demaille  <akim@epita.fr>
1043
1044         * src/output.c (prepare): Drop the muscle `ntbase' which
1045         duplicates ntokens.
1046         * src/bison.simple: Formatting/comment changes.
1047         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
1048         is an undocumented synonym.
1049
1050 2001-12-22  Akim Demaille  <akim@epita.fr>
1051
1052         * src/output.c (output_table_data): Change the prototype to use
1053         `int' for array ranges: some invocations do pass an int, not a
1054         short.
1055         Reported by Wayne Green.

1060         Reported by Mike Castle.
1061
1062         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
1063         * tests/regression.at (Web2c): Rename as...
1064         (Web2c Report): this.
1065         (Web2c Actions): New.
1066
1067 2001-12-22  Akim Demaille  <akim@epita.fr>

1073         * tests/regression.at (Web2c): New.
1074
1075 2001-12-18  Akim Demaille  <akim@epita.fr>
1076
1077         Some host fail on `assert (!"foo")', which expands to
1078         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
1079         Reported by Nelson Beebee.
1080
1081         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
1082         `#define it_succeeded 0' and `assert (it_succeeded)'.
1083
1084 2001-12-17  Marc Autret  <autret_m@epita.fr>
1085
1086         * src/bison.simple: Don't hard code the skeleton line and filename.
1087         * src/output.c (output_parser): Rename 'line' as 'output_line'.
1088         New line counter 'skeleton_line' (skeleton-line muscle).
1089
1090 2001-12-17  Paul Eggert  <eggert@twinsun.com>
1091
1092         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
1093         YYDEBUG must be defined to a nonzero value.
1094
1095         * src/bison.simple (yytname): Do not assume that the user defines

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

1454
1455 2001-12-10  Akim Demaille  <akim@epita.fr>
1456
1457         * src/reader.c (reader): Calling symbols_output once is enough.
1458
1459 2001-12-10  Akim Demaille  <akim@epita.fr>
1460
1461         Now that states have a complete set of members, the linked list of
1462         reductions is useless: just fill directly the state's reductions
1463         member.
1464
1465         * src/state.h (struct reductions): Remove member `number' and
1466         `next'.
1467         * src/LR0.c (first_reduction, last_reduction): Remove.
1468         (save_reductions): Don't link the new reductions, store them in
1469         this_state.
1470         * src/lalr.c (set_state_table): No need to attach reductions to
1471         states, it's already done.
1472         * src/output.c (output_actions): No longer free the shifts, then
1473         the reductions, then the states: free all the states and their
1474         members.
1475
1476 2001-12-10  Akim Demaille  <akim@epita.fr>
1477
1478         * src/options.c (OPTN, DRTV, BOTH): New.
1479         (option_table): Use them.
1480
1481         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1482         the job of system.h.
1483         * src/options.c: Don't include stdio.h and xalloc.h for the same
1484         reasons.
1485
1486 2001-12-10  Akim Demaille  <akim@epita.fr>
1487
1488         * src/output.c (output, prepare): Make sure the values of the
1489         muscles `action' and `prologue' are 0-terminated.
1490
1491 2001-12-10  Akim Demaille  <akim@epita.fr>
1492
1493         Clean up GCC warnings.
1494
1495         * src/reader.c (copy_action): `buf' is not used.
1496         (parse_skel_decl): Be static.
1497         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1498         * src/options.h (create_long_option_table): Have a real prototype.
1499         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1500         (hash_delete_at): Return const void *.
1501         Adjust casts to preserve the const.
1502
1503 2001-12-10  Akim Demaille  <akim@epita.fr>
1504
1505         * configure.in: Require 2.52g.
1506         M4 is not needed, but AUTOM4TE is.
1507         * m4/m4.m4: Remove.
1508         * tests/Makefile.am: Adjust.
1509
1510 2001-12-10  Akim Demaille  <akim@epita.fr>
1511
1512         One structure for states is enough, even though theoretically
1513         there are LR(0) states and LALR(1) states.
1514
1515         * src/lalr.h (state_t): Remove.
1516         (state_table): Be state_t **, not state_t *.
1517         * src/state.h (core, CORE_ALLOC): Rename as...
1518         (state_t, STATE_ALLOC): this.
1519         Add the LALR(1) members: shifts, reductions, errs.
1520         * src/LR0.c (state_table): Rename as...
1521         (state_hash): this, to avoid name clashes with the global
1522         `state_table'.
1523         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1524         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
1525
1526 2001-12-10  Akim Demaille  <akim@epita.fr>
1527
1528         Bison dumps core on bash.y.
1529         Reported by Pascal Bart.
1530
1531         * src/warshall.c (bitmatrix_print): New.
1532         (TC): Use it.
1533         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1534         j must be the outer loop.
1535         * tests/regression.at (Broken Closure): New.
1536
1537 2001-12-05  Akim Demaille  <akim@epita.fr>
1538
1539         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1540         its argument.
1541         Reported by Peter Hámorský.
1542
1543 2001-12-05  Akim Demaille  <akim@epita.fr>
1544
1545         * src/conflicts.c (err_table): Remove.
1546         (resolve_sr_conflict): Adjust.
1547         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1548         Rename as...
1549         (state_t.reductions, state_t.shifts): this.
1550
1551 2001-12-05  Akim Demaille  <akim@epita.fr>
1552
1553         * src/reduce.c (reduce_grammar_tables): No longer disable the
1554         removal of useless rules via CPP but via `if (0)', so that the
1555         compiler still check the code is valid.
1556         For instance, it should have noticed `rline' no longer exists: use
1557         the `line' member of rule_t.
1558         * src/gram.c (dummy, rline): Remove, unused.
1559
1560 2001-12-05  Akim Demaille  <akim@epita.fr>
1561
1562         * src/output.c (pack_vector): Use assert, not berror.
1563         * src/main.c (berror): Remove, unused.
1564
1565 2001-12-05  Akim Demaille  <akim@epita.fr>
1566
1567         New experimental feature: if --verbose --trace output all the
1568         items of a state, not only its kernel.
1569
1570         * src/print.c (print_core): If `trace_flag', then invoke closure
1571         before outputting the items of the state (print_core is no longer
1572         a correct name them).
1573         (print_results): Invoke new_closure/free_closure if needed.
1574
1575 2001-12-05  Akim Demaille  <akim@epita.fr>
1576
1577         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1578         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1579         (nitemset): for consistency with the rest of the project.
1580
1581 2001-12-05  Akim Demaille  <akim@epita.fr>
1582
1583         * src/closure.c (print_closure): Improve.
1584         (closure): Use it for printing input and output.
1585
1586 2001-12-05  Akim Demaille  <akim@epita.fr>
1587
1588         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1589         indexed by nonterminals.
1590
1591 2001-12-05  Akim Demaille  <akim@epita.fr>
1592
1593         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1594         what it was!).
1595         * src/warshall.h: Remove accidental duplication of the content.
1596
1597 2001-12-05  Akim Demaille  <akim@epita.fr>
1598
1599         * src/closure.c (set_fderives): De-obfuscate.
1600
1601 2001-12-05  Akim Demaille  <akim@epita.fr>
1602

1604
1605 2001-12-05  Akim Demaille  <akim@epita.fr>
1606
1607         * src/closure.c (set_firsts): De-obfuscate.
1608
1609 2001-12-05  Akim Demaille  <akim@epita.fr>
1610
1611         * src/output.c (action_row): De-obfuscate
1612         using the good o' techniques: arrays not pointers, variable
1613         locality, BITISSET, RESETBIT etc.
1614
1615 2001-12-05  Akim Demaille  <akim@epita.fr>
1616
1617         Pessimize the code to simplify it: from now on, all the states
1618         have a valid SHIFTS, which NSHIFTS is possibly 0.
1619
1620         * src/LR0.c (shifts_new): Be global and move to..
1621         * src/state.c, src/state.h: here.
1622         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1623         * src/print_graph: Adjust.
1624
1625 2001-12-05  Akim Demaille  <akim@epita.fr>
1626
1627         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1628         * src/conflicts.c: Use it.
1629         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1630         incorrectly ``simplified''.
1631
1632 2001-12-05  Akim Demaille  <akim@epita.fr>
1633
1634         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1635         using the good o' techniques: arrays not pointers, variable
1636         locality, BITISSET, RESETBIT etc.
1637
1638 2001-12-05  Akim Demaille  <akim@epita.fr>
1639
1640         * src/state.h (SHIFT_SYMBOL): New.
1641         * src/conflicts.c: Use it to deobfuscate.
1642
1643 2001-12-05  Akim Demaille  <akim@epita.fr>
1644
1645         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1646         (print_reductions): De-obfuscate using the good o' techniques:
1647         arrays not pointers, variable locality, BITISSET.
1648
1649 2001-12-05  Akim Demaille  <akim@epita.fr>
1650
1651         * src/conflicts.c (print_reductions): Arrays, not pointers.
1652         Use BITISSET.
1653
1654 2001-12-05  Akim Demaille  <akim@epita.fr>
1655
1656         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1657
1658 2001-12-05  Akim Demaille  <akim@epita.fr>
1659
1660         * src/conflicts.c (print_reductions): Improve variable locality.
1661
1662 2001-12-05  Akim Demaille  <akim@epita.fr>
1663
1664         * src/conflicts.c (print_reductions): Pessimize, but clarify.

1669
1670 2001-12-05  Akim Demaille  <akim@epita.fr>
1671
1672         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
1673         * src/lalr.c: Use them.
1674
1675 2001-12-05  Akim Demaille  <akim@epita.fr>
1676
1677         * src/LR0.c (augment_automaton): Formatting changes.
1678         Better variable locality.
1679
1680 2001-12-05  Akim Demaille  <akim@epita.fr>
1681
1682         * src/lalr.c (matrix_print): New.
1683         (transpose): Use it.
1684         Use arrays instead of pointers.
1685
1686 2001-12-05  Akim Demaille  <akim@epita.fr>
1687
1688         * src/lalr.c (maxrhs): Move to...
1689         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1690         * src/lalr.c (build_relations): Adjust.
1691
1692 2001-12-05  Akim Demaille  <akim@epita.fr>
1693
1694         * src/lalr.c (transpose): Free the memory allocated to the
1695         argument, as it is replaced by the results by the unique caller.
1696         (build_relations): Merely invoke transpose: it handles the memory
1697         deallocation.
1698         Improve variable locality.
1699         Avoid variables used as mere abbreviations.
1700         (compute_lookaheads): Use arrays instead of pointers.
1701
1702 2001-12-05  Akim Demaille  <akim@epita.fr>
1703
1704         * src/lalr.c (initialize_F): Improve variable locality.
1705         Avoid variables used as mere abbreviations.
1706
1707 2001-12-05  Akim Demaille  <akim@epita.fr>
1708
1709         * src/derives.c (print_derives): Display the ruleno.
1710         * src/lalr.c (initialize_F, transpose): Better variable locality
1711         to improve readability.
1712         Avoid variables used as mere abbreviations.
1713
1714 2001-12-05  Akim Demaille  <akim@epita.fr>
1715
1716         * src/lalr.c (traverse): Use arrays instead of pointers.
1717
1718 2001-12-05  Akim Demaille  <akim@epita.fr>
1719
1720         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1721         the handling of squeue.
1722         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1723
1724 2001-12-05  Akim Demaille  <akim@epita.fr>
1725
1726         Because useless nonterminals are now kept alive (instead of being
1727         `destroyed'), we now sometimes examine them, and store information
1728         related to them.  Hence we need to know their number, and adjust
1729         memory allocations.
1730
1731         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1732         static.
1733         * src/LR0.c (allocate_itemsets): The memory allocated to
1734         `symbol_count' was used for two different purpose: once to count
1735         the number of occurrences of each symbol, and later reassigned to
1736         `shift_symbol', containing the symbol that can be shifted from a
1737         given state.
1738         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1739         only, and...
1740         (new_itemsets): Allocate `shift_symbol' here.
1741         (allocate_itemsets): symbol_count includes useless nonterminals.
1742         Make room for them.
1743         (free_storage): Use `free', not `XFREE', for pointers that cannot
1744         be null.
1745
1746 2001-12-05  Akim Demaille  <akim@epita.fr>
1747
1748         * src/nullable.c (set_nullable): Deobfuscate the handling of
1749         ritem.
1750         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1751
1752 2001-12-05  Akim Demaille  <akim@epita.fr>
1753
1754         * src/gram.c, src/gram.h (ritem_print): New.
1755         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1756         (This useless function was defined only to work around VMS linkers
1757         that can't handle compilation units with variables only).
1758         * src/reduce.c (dump_grammar): Use it to trace the construction of
1759         ritem.
1760
1761 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1762
1763         * src/bison.simple (union yyalloc): Change member names
1764         to be the same as the stack names.
1765         (yyparse): yyptr is now union yyalloc *, not char *.
1766         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1767         and may generate better code on some machines.
1768         (yystpcpy): Use prototype if __STDC__ is defined, not just
1769         if __cplusplus is defined.
1770
1771 2001-11-30  Akim Demaille  <akim@epita.fr>
1772
1773         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1774         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1775         Gettext doesn't compile cleanly, and dies with -Werror.
1776         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1777         Include WARNING_CFLAGS here.
1778         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1779         before being defined.
1780
1781 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1782
1783         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1784         First arg is int, not unsigned.
1785         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1786         (SIZE_MAX, UINT_MAX): New macros.
1787         (quotearg_n_options): Abort if N is negative.
1788         Avoid overflow check on hosts where size_t is 64 bits and int
1789         is 32 bits, as overflow is impossible there.
1790         Fix off-by-one typo that caused unnecessary reallocation.
1791
1792 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1793
1794         Name space cleanup in generated parser.
1795
1796         * doc/bison.texinfo (Bison Parser): Discuss system headers
1797         and their effect on the user name space.
1798
1799         * src/bison.simple:
1800         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1801         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1802         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1803
1804         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1805         on user names when possible.
1806
1807         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1808         Simplify test for whather <alloca.h> exists.
1809
1810         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.

1883         (union yyalloc): New type.
1884         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1885         an arbitrary restriction on hosts where size_t is wider than int.
1886
1887         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1888         a parser stack overflow.  Allocate just one block of memory for all
1889         three stacks, instead of allocating three blocks; this typically is
1890         faster and reduces fragmentation.
1891
1892         Do not limit the number of items in the stack to a value that fits
1893         in 'int', as this is an arbitrary limit on hosts with 64-bit
1894         size_t and 32-bit int.

1955
1956         * src/closure.c (closure): No longer optimize the special case

2192         * src/derives.c: Likewise.
2193         * src/reduce.c: (inaccessable_symbols): Using if is better style

2222
2223         * src/vcg.c: You do the output, so you are responsible of the

2226         (print_actions): Don't output the actions as part of the nodes,
2227         since that's the job of the edges.

2321         * tests/calc.at, tests/output.at, tests/regression.at,
2322         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
2323         now the tests are run in private dirs, therefore AC_CLEANUP and
2324         family can be simplified to 0-ary.
2325         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
2326         use abs. path to find config.h.
2327         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

2351         arg_offset.
2352         arg is const.

2354         token_buffer not to change.

3273
3274         * src/bison.simple (yyparse): Don't take the address of an

3284         completely wrong.

3323         bound to true.
3324         (read_declarations): Add case for macro definition.
3325         (copy_identifier): New.
3326         (parse_macro_decl): Read macro identifiers using copy_identifier

3361         with something new. Skeletons are now processed character by character

3690
3691 2001-02-21  Akim Demaille  <akim@epita.fr>
3692
3693         * src/reader.c (gensym): `gensym_count' is your own.
3694         Use a static buf to create the symbol name, as token_buffer is no
3695         longer a buffer.
3696
3697 2001-02-08  Akim Demaille  <akim@epita.fr>
3698
3699         * src/conflicts.c (conflict_report): Be sure not to append to res
3700         between two calls, which could happen if both first sprintf were

3702
3703 2001-02-08  Akim Demaille  <akim@epita.fr>
3704
3705         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
3706         New, from fileutils 4.0.37.
3707         * configure.in: Require Autoconf 2.49c.  I took some time before
3708         making this decision.  This is the only way out for portability
3709         issues in Bison, it would mean way too much duplicate effort to
3710         import in Bison features implemented in 2.49c since 2.13.
3711         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
3712
3713 2001-02-02  Akim Demaille  <akim@epita.fr>

3719
3720         Get rid of the ad hoc handling of token_buffer in the scanner: use
3721         the obstacks.
3722
3723         * src/lex.c (token_obstack): New.
3724         (init_lex): Initialize it.  No longer call...
3725         (grow_token_buffer): this.  Remove it.
3726         Adjust all the places which used it to use the obstack.
3727
3728 2001-01-19  Akim Demaille  <akim@epita.fr>
3729
3730         * src/lex.h: Rename all the tokens:
3731         s/\bENDFILE\b/tok_eof/g;
3732         s/\bIDENTIFIER\b/tok_identifier/g;
3733         etc.
3734         Let them be enums, not #define, to ease debugging.
3735         Adjust all the code.
3736
3737 2001-01-18  Akim Demaille  <akim@epita.fr>
3738
3739         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
3740         * src/lex.c (maxtoken, grow_token_buffer): Static.
3741
3742 2001-01-18  Akim Demaille  <akim@epita.fr>
3743
3744         Since we now use obstacks, more % directives can be enabled.
3745
3746         * src/lex.c (percent_table): Also accept `%yacc',
3747         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3748         `%debug'.
3749         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3750         instead of returning a token.
3751         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3752         * src/reader.c (read_declarations): Adjust.
3753         * src/files.c (open_files): Don't call `compute_base_names', don't
3754         compute `attrsfile' since they depend upon data which might be
3755         *in* the input file now.
3756         (output_files): Do it here.
3757         * src/output.c (output_headers): Document the fact that this patch
3758         introduces a guaranteed SEGV for semantic parsers.
3759         * doc/bison.texinfo: Document them.
3760         * tests/suite.at: Exercise these %options.
3761
3762 2000-12-20  Akim Demaille  <akim@epita.fr>
3763
3764         Also handle the output file (--verbose) with obstacks.
3765
3766         * files.c (foutput): Remove.
3767         (output_obstack): New.
3768         Adjust all dependencies.
3769         * src/conflicts.c: Return a string.
3770         * src/system.h (obstack_grow_string): Rename as...
3771         (obstack_sgrow): this.  Be ready to work with non literals.
3772         (obstack_fgrow4): New.
3773
3774 2000-12-20  Akim Demaille  <akim@epita.fr>
3775
3776         * src/files.c (open_files): Fix the computation of short_base_name
3777         in the case of `-o foo.tab.c'.
3778
3779 2000-12-20  Akim Demaille  <akim@epita.fr>
3780
3781         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
3782         (copy_dollar): Now that everything uses obstacks, get rid of the
3783         FILE * parameters.
3784
3785 2000-12-20  Akim Demaille  <akim@epita.fr>
3786
3787         * src/files.c (open_files): Actually the `.output' file is based
3788         on the short_base_name, not base_name.
3789         * tests/suite.at (Checking output file names): Adjust.
3790
3791 2000-12-20  Akim Demaille  <akim@epita.fr>
3792
3793         * src/bison.s1: Remove, we now use directly...
3794         * src/bison.simple: this.
3795         * src/Makefile.am: Use pkgdata instead of data.
3796

3812         Adjust dependencies.
3813
3814 2000-12-19  Akim Demaille  <akim@epita.fr>
3815
3816         * src/files.c (strsuffix): New.
3817         (stringappend): Be just like strcat but allocate.
3818         (base_names): Eve out from open_files.
3819         Try to simplify the rather hairy computation of base_name and
3820         short_base_name.
3821         (open_files): Use it.
3822         * tests/suite.at (Checking output file names): New test.

3829         `$'.
3830         * src/bison.s1: s/$/%% actions/.
3831         * src/bison.hairy: Likewise.
3832
3833 2000-12-19  Akim Demaille  <akim@epita.fr>
3834
3835         * src/output.c (output_parser): Compute the `#line' lines when
3836         there are.
3837         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
3838         Suggested by Hans Aberg.
3839
3840 2000-12-19  Akim Demaille  <akim@epita.fr>
3841
3842         Let the handling of the skeleton files be local to the procedures
3843         that use it.
3844
3845         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No

3861
3862         * src/files.c (open_files): Yipee!  We no longer need all the code
3863         looking for `/tmp' since we have no tmp file.
3864
3865 2000-12-19  Akim Demaille  <akim@epita.fr>
3866
3867         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

3877         `timestamp' and `text' in the default YYLTYPE.

3880
3881         * src/reader.c (copy_definition, parse_union_decl, copy_action)
3882         (copy_guard): Quote the file names.
3883         Reported by Laurent Mascherpa.

3893
3894         * lib/obstack.h: Formatting changes.
3895         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3896         prevents type checking.
3897         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3898         cast the value to (void *): assigning a `foo *' to a `void *'
3899         variable is valid.
3900         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

3934         defining.
3935         * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
3936
3937 2000-11-07  Akim Demaille  <akim@epita.fr>
3938
3939         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
3940         Merge in a single CPP if/else.
3941
3942 2000-11-07  Akim Demaille  <akim@epita.fr>
3943
3944         * src/output.c (output): Remove useless variables.
3945         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
3946         argument `data' for consistency with the prototypes.

3951         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
3952         `const' their input argument (`data' or `address').

3982         it no longer has to remove tmp files, just call `output_files'
3983         when there are no errors.

4088         When a literal string is used to define two different tokens,
4089         `bison -v' segfaults.
4090         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
4091
4092         * tests/regression.m4: New file.
4093         Include the core of the sample provided by Piotr Gackiewicz.

4095         properly.
4096
4097 2000-10-04  Akim Demaille  <akim@epita.fr>
4098
4099         * src/reader.c (parse_expect_decl): Keep `count' within the size
4100         of `buffer'.
4101         From Neil Booth.
4102
4103 2000-10-02  Paul Eggert  <eggert@twinsun.com>
4104
4105         * bison.s1 (yyparse): Assign the default value
4106         unconditionally, to avoid a GCC warning and make the parser a
4107         tad smaller.
4108
4109 2000-10-02  Akim Demaille  <akim@epita.fr>
4110
4111         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
4112         options.
4113
4114 2000-10-02  Akim Demaille  <akim@epita.fr>
4115
4116         * src/derives.c, src/print.c, src/reduce.c: To ease the
4117         translation, move some `\n' out of the translated strings.
4118
4119 2000-10-02  Akim Demaille  <akim@epita.fr>
4120
4121         The location tracking mechanism is precious for parse error
4122         messages.  Nevertheless, it is enabled only when `@n' is used in
4123         the grammar, which is a different issue (you can use it in error
4124         message, but not in the grammar per se).  Therefore, there should
4125         be another means to enable it.
4126
4127         * src/getargs.c (getargs): Support `--locations'.
4128         (usage): Report it.
4129         * src/getargs.h (locationsflag): Export it.
4130         * src/lex.c (percent_table): Support `%locations'.
4131         * src/reader.c (yylsp_needed): Remove this variable, now replaced
4132         with `locationsflag'.
4133         * doc/bison.texinfo: Document `--locations' and `%locations'.
4134         Sort the options.
4135         * tests/calc.m4: Test it.
4136
4137         For regularity of the names, replace each
4138         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4139         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4140         In addition replace each `flag' with `_flag'.
4141
4142 2000-10-02  Akim Demaille  <akim@epita.fr>
4143
4144         Also test parse error messages, including with YYERROR_VERBOSE.
4145
4146         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4147         associative).
4148         Use it to check the computations.
4149         Use it to check `nonassoc' is honored.
4150         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4151         `--yyerror-verbose'.
4152         (_AT_CHECK_CALC): Adjust to this option.
4153         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4154
4155 2000-10-02  Akim Demaille  <akim@epita.fr>
4156
4157         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
4158         the latter demonstrates a flaw in the handling of non debugging
4159         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4160         was used in order to simplify:
4161
4162         #if YYDEBUG
4163         if (yydebug)
4164         {
4165         ...
4166         }
4167         #endif
4168
4169         into
4170
4171         if (yydebug)
4172         {
4173         ...
4174         }
4175
4176         unfortunately this leads to a CPP conflict when
4177         `--name-prefix=foo' is used since it produces `#define yydebug
4178         foodebug'.
4179
4180         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4181         (YYDPRINTF): New macro.
4182         Spread its use.
4183         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4184         the bison options.
4185         Also test `--verbose', `--defines' and `--name-prefix'.
4186
4187 2000-10-02  Akim Demaille  <akim@epita.fr>
4188
4189         Improve the readability of the produced parsers.
4190
4191         * src/bison.s1: Formatting changes.
4192         Improve the comment related to the `$' mark.
4193         (yydefault): Don't fall through to `yyresume': `goto' there.
4194         * src/output.c (output_parser): When the `$' is met, skip the end
4195         of its line.
4196         New variable, `number_of_dollar_signs', to check there's exactly
4197         one `$' in the parser skeleton.
4198
4199 2000-10-02  Akim Demaille  <akim@epita.fr>
4200
4201         * lib/xstrdup.c: New file, from the fileutils.
4202         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4203         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4204         instead of strlen + xmalloc + strcpy.
4205         * src/symtab.c (copys): Remove, use xstrdup instead.
4206
4207 2000-10-02  Akim Demaille  <akim@epita.fr>
4208
4209         * src/gram.h (associativity): New enum type which replaces the
4210         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4211         `right_assoc', `left_assoc' and `non_assoc'.
4212         Adjust all dependencies.
4213         * src/reader.c: Formatting changes.
4214         (LTYPESTR): Don't define it, use it as a literal in
4215         `reader_output_yylsp'.
4216         * src/symtab.h (symbol_class): New enum type which replaces the
4217         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4218         `sunknown', `stoken and `snterm'.
4219
4220 2000-10-02  Akim Demaille  <akim@epita.fr>
4221
4222         * src/getargs.c (fixed_outfiles): Rename as...
4223         (yaccflag): for consistency and accuracy.
4224         Adjust dependencies.
4225
4226 2000-10-02  Akim Demaille  <akim@epita.fr>
4227
4228         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4229         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4230         difficult and introduced a lot of core dump.  It turns out that
4231         Bison used an implementation of `xmalloc' based on `calloc', and
4232         at various places it does depend upon the initialization to 0.  I
4233         have not tried to isolate the pertinent places, and all the former
4234         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4235         someone should address this issue.
4236
4237         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4238         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

4245
4246         Various anti-`extern in *.c' changes.
4247
4248         * src/system.h: Include `assert.h'.
4249
4250 2000-10-02  Akim Demaille  <akim@epita.fr>
4251
4252         * src/state.h (nstates, final_state, first_state, first_shift)
4253         (first_reduction): Move their exportation from here...
4254         * src/LR0.h: to here.
4255         Adjust dependencies.
4256         * src/getargs.c (statisticsflag): New variable.

4323
4324 2000-10-02  Akim Demaille  <akim@epita.fr>
4325
4326         * src/lalr.h: New file.

4329
4330 2000-10-02  Akim Demaille  <akim@epita.fr>
4331
4332         * src/output.c (token_actions): Introduce a temporary array,
4333         YYDEFACT, that makes it possible for this function to use
4334         output_short_table.
4335
4336 2000-10-02  Akim Demaille  <akim@epita.fr>
4337
4338         `user_toknums' is output as a `short[]' in `output.c', while it is
4339         defined as a `int[]' in `reader.c'.  For consistency with the
4340         other output tables, `user_toknums' is now defined as a table of
4341         shorts.
4342
4343         * src/reader.c (user_toknums): Be a short table instead of an int
4344         table.
4345         Adjust dependencies.
4346
4347         Factor the short table outputs.
4348
4349         * src/output.c (output_short_table): New function.
4350         * src/output.c (output_gram, output_stos, output_rule_data)

4352
4353 2000-10-02  Akim Demaille  <akim@epita.fr>
4354
4355         * src/output.c (output): Topological sort of the functions, in
4356         order to get rid of the `static' prototypes.
4357         No longer use `register'.
4358         * src/output.h: New file.
4359         Propagate its inclusion in files explicitly prototyping functions
4360         from output.c.

4372         (new_closure, free_closure): these.  Adjust dependencies.
4373         * src/LR0.c: Formatting changes, topological sort, use of
4374         cloture.h.

4382         inclusion.
4383         Don't define PARAMS.
4384         * src/system.h: Define PARAMS.
4385         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
4386         purpose of config.h.  system.h must not try to fix wrong
4387         definitions in config.h.

4401         Use these macros to test bison with options `', `--raw',
4402         `--debug', `--yacc', `--yacc --debug'.
4403
4404 2000-09-19  Akim Demaille  <akim@epita.fr>

4427

4465         (VERSION_STRING): Remove.
4466
4467 2000-04-14  Akim Demaille  <akim@epita.fr>
4468
4469         * src/reader.c (copy_comment2): New function, same as former

4524         * configure.in: Adjust.
4525         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

4549         the file name, not the whole `#line LINE FILE'.
4550
4551 2000-03-17  Akim Demaille  <akim@epita.fr>
4552
4553         On syntax errors, report the token on which we choked.
4554
4555         * src/bison.s1 (yyparse): In the label yyerrlab, when

4573
4574         * src/reader.c (copy_definition): Use copy_string and
4575         copy_comment.  Removed now unused `match', `ended',
4576         `cplus_comment'.
4577         (copy_comment, copy_string): Moved, to be visible from
4578         copy_definition.
4579
4580 2000-03-17  Akim Demaille  <akim@epita.fr>
4581
4582         * src/reader.c (copy_string): Declare `static inline'.  No
4583         problems with inline, since it is checked by configure.

4604
4605         Change the handling of @s so that they behave exactly like $s.
4606         There is now a pseudo variable @$ (readble and writable), location
4607         of the lhs of the rule (by default ranging from the location of
4608         the first symbol of the rhs, to the location of the last symbol,
4609         or, if the rhs is empty, YYLLOC).
4610
4611         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4612         yyval.
4613         (yyparse): When providing a default semantic action, provide a
4614         default location action.
4615         (after the $): No longer change `*YYLSP', just stack YYLOC the
4616         same way you stack YYVAL.
4617         * src/reader.c (read_declarations): Use warns.
4618         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4619         (copy_action, case '@'): Likewise.
4620         Use a standard error message, to save useless work from
4621         translators.
4622
4623 2000-03-17  Akim Demaille  <akim@epita.fr>
4624

4632         Makefile now handles them.
4633
4634 2000-03-16  Akim Demaille  <akim@epita.fr>
4635

4640
4641 2000-03-16  Akim Demaille  <akim@epita.fr>
4642
4643         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4644         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4645         One `#if YYDEBUG' remains, since it uses variables which are
4646         defined only if `YYDEBUG != 0'.
4647
4648 2000-03-16  Akim Demaille  <akim@epita.fr>
4649
4650         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
4651         and related variables so that the similarities are highlighted.

4671         * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
4672         handled via src/Makefile.am.
4673         (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
