 159 2002-02-14  Paul Eggert  <eggert@twinsun.com>
 160
 161         Remove the support for C++ namespace cleanliness; it was
 162         causing more problems than it was curing, since it didn't work
 163         properly on some nonstandard C++ compilers.  This can wait
 164         for a proper C++ parser.
 165
 166         * NEWS: Document this.
 167         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention

 183
 184         * src/output.c (output_rule_data): Don't output NULL, it might
 185         not be defined yet.

 205
 206 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 207
 208         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
 209         more consistent when naming methods and variables.  Put preprocessor
 210         directives around tables only needed for debugging.
 211
 212 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>

 235         not expanded by m4.
 236
 237 2002-02-05  Akim Demaille  <akim@epita.fr>
 238
 239         * data/bison.c++: Adjust to the M4 back end.
 240         More is certainly needed.

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

 269         * src/scan-skel.l: Instead of scanning the skeletons, it now

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

 294
 295 2002-01-29  Paul Eggert  <eggert@twinsun.com>
 296
 297         * src/bison.simple (YYSIZE_T): Do not define merely because
 298         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 299         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 300
 301 2002-01-27  Akim Demaille  <akim@epita.fr>

 303         Fix `%nonassoc and eof'.
 304
 305         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
 306         which were not properly copied!  Replace
 307         memcpy (res->errs, src->errs, src->nerrs);
 308         with
 309         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
 310         !!!
 311         * tests/regression.at (%nonassoc and eof): Adjust to newest

 324         forces `.' in the PATH.

 377
 378 2002-01-11  Akim Demaille  <akim@epita.fr>
 379
 380         * configure.in: Use AC_FUNC_STRNLEN.
 381         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
 382
 383 2002-01-09  Akim Demaille  <akim@epita.fr>
 384
 385         * src/files.c, src/files.h (output_infix): New.
 386         (tab_extension): Remove.
 387         (compute_base_names): Compute the former, drop the latter.
 388         * src/output.c (prepare): Insert the muscles `output-infix', and
 389         `output-suffix'.
 390         * src/parse-skel.y (string, string.1): New.
 391         (section.header): Use it.
 392         (section.yacc): Remove.
 393         (prefix): Remove too.
 394         * src/scan-skel.l: Adjust.
 395         * src/bison.simple, src/bison.hairy: Adjust.
 396
 397 2002-01-09  Akim Demaille  <akim@epita.fr>
 398
 399         * configure.in (WERROR_CFLAGS): Compute it.
 400         * src/Makefile.am (CFLAGS): Pass it.
 401         * tests/atlocal.in (CFLAGS): Idem.
 402         * src/files.c: Fix a few warnings.
 403         (get_extension_index): Remove, unused.
 404
 405 2002-01-08  Akim Demaille  <akim@epita.fr>
 406
 407         * src/getargs.c (AS_FILE_NAME): New.
 408         (getargs): Use it to convert DOSish file names.
 409         * src/files.c (base_name): Rename as full_base_name to avoid
 410         clashes with `base_name ()'.
 411         (filename_split): New.
 412         (compute_base_names): N-th rewrite, using filename_split.
 413
 414 2002-01-08  Akim Demaille  <akim@epita.fr>
 415
 416         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
 417         New, stolen from the Fileutils 4.1.
 418         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
 419         * configure.in: Check for the presence of memrchr, and of its
 420         prototype.
 421
 422 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
 423
 424         * lib/hash.h (__P): Added definition for this macro.
 425         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
 426         BUILT_SOURCES, to ensure they are generated first.
 427         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
 428         %error-verbose to allow bootstrapping with bison 1.30x.
 429
 430 2002-01-06  Akim Demaille  <akim@epita.fr>
 431
 432         * src/reader.c (parse_braces): Don't fetch the next char, the
 433         convention is to fetch on entry.
 434         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
 435         'switch' without a following semicolon.
 436         * tests/regression.at (braces parsing): New.
 437
 438 2002-01-06  Akim Demaille  <akim@epita.fr>
 439
 440         Bison is dead wrong in its RR conflict reports.
 441
 442         * tests/torture.at (GNU Cim Grammar): New.
 443         * src/conflicts.c (count_rr_conflicts): Fix.
 444
 445 2002-01-06  Akim Demaille  <akim@epita.fr>
 446
 447         Creating package.m4 from configure.ac causes too many problems.
 448
 449         * tests/Makefile.am (package.m4): Create it by hand,
 450         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
 451
 452 2002-01-06  Akim Demaille  <akim@epita.fr>
 453
 454         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
 455         skeleton.h.
 456
 457 2002-01-04  Paul Eggert  <eggert@twinsun.com>
 458
 459         * doc/bison.texinfo (Debugging):
 460         Remove YYSTDERR; it's no longer defined or used.
 461         Also, s/cstdio.h/cstdio/.
 462
 463 2002-01-03  Akim Demaille  <akim@epita.fr>
 464
 465         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
 466
 467 2002-01-03  Akim Demaille  <akim@epita.fr>
 468
 469         * src/parse-skel.y (process_skeleton): Don't bind the parser's
 470         tracing code to --trace, wait for a better --trace option, with
 471         args.
 472
 473 2002-01-03  Akim Demaille  <akim@epita.fr>
 474
 475         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
 476         The ISO C++ standard is extremely clear about it: stderr is
 477         considered a macro, not a regular symbol (see table 94 `Header
 478         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
 479         Therefore std:: does not apply to it.  It still does with fprintf.
 480         Also, s/cstdio.h/cstdio/.
 481
 482 2002-01-03  Akim Demaille  <akim@epita.fr>
 483
 484         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
 485         for non system headers.
 486
 487 2002-01-02  Akim Demaille  <akim@epita.fr>
 488
 489         Equip the skeleton chain with location tracking, runtime trace,
 490         pure parser and scanner.
 491
 492         * src/parse-skel.y: Request a pure parser, locations, and prefix
 493         renaming.
 494         (%union): Having several members with the same type does not help
 495         type mismatches, simplify.
 496         (YYPRINT, yyprint): New.
 497         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
 498         (skel_error): this.
 499         Handle locations.
 500         * src/scan-skel.l: Adjust to these changes.
 501         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
 502         (LOCATION_PRINT, skel_control_t): New.
 503
 504 2001-12-30  Akim Demaille  <akim@epita.fr>
 505
 506         * src/parse-skel.y: Get rid of the shift/reduce conflict:
 507         replace `gb' with BLANKS.
 508         * src/scan-skel.l: Adjust.
 509
 510 2001-12-30  Akim Demaille  <akim@epita.fr>
 511
 512         * src/system.h: We don't need nor want bcopy.
 513         Throw away MS-DOS crap: we don't need getpid.
 514         * configure.in: We don't need strndup.  It was even causing
 515         problems: because Flex includes the headers *before* us,
 516         _GNU_SOURCE is not defined by config.h, and therefore strndup was
 517         not visible.
 518         * lib/xstrndup.c: New.
 519         * src/scan-skel.l: Use it.
 520         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
 521         * src/parse-skel.y: Use %directives instead of #defines.
 522
 523 2001-12-30  Akim Demaille  <akim@epita.fr>
 524
 525         * src/skeleton.h: New.
 526         * src/output.c (output_parser, output_master_parser): Remove, dead
 527         code.
 528         * src/output.h (get_lines_number, actions_output, guards_output)
 529         (token_definitions_output): Prototype them.
 530         * src/parse-skel.y: Add the license notice.
 531         Include output.h and skeleton.h.
 532         (process_skeleton): Returns void, and takes a single parameter.
 533         * src/scan-skel.l: Add the license notice.
 534         Include skeleton.h.
 535         Don't use %option yylineno: it seems that then Flex imagines
 536         REJECT has been used, and therefore it won't reallocate its
 537         buffers (which makes no other sense to me than a bug).  It results
 538         in warnings for `unused: yy_flex_realloc'.
 539
 540 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
 541
 542         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 543         (MUSCLE_INSERT_PREFIX): ...to there.
 544         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 545         (MUSCLE_INSERT_PREFIX): Move from here...
 546
 547         * src/bison.hairy: Add a section directive.  Put braces around muscle
 548         names.  This parser skeleton is still broken, but Bison should not
 549         choke on a bad muscle 'syntax'.
 550         * src/bison.simple: Add a section directive.  Put braces around muscle
 551         names.
 552
 553         * src/files.h (strsuffix, stringappend): Add declarations.
 554         (tab_extension): Add declaration.
 555         (short_base_name): Add declaration.
 556
 557         * src/files.c (strsuffix, stringappend): No longer static.  These
 558         functions are used in the skeleton parser.
 559         (tab_extension): New.
 560         (compute_base_names): Use the computations done in this function
 561         to guess if the generated parsers should have '.tab' in their
 562         names.
 563         (short_base_name): No longer static.
 564
 565         * src/output.c (output_skeleton): New.
 566         (output): Disable call to output_master_parser, and give a try to
 567         a new skeleton handling system.
 568         (guards_output, actions_output): No longer static.
 569         (token_definitions_output, get_lines_number): No longer static.
 570
 571         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
 572
 573         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
 574         parse-skel.y.
 575
 576         * src/parse-skel.y: New file.
 577         * src/scan-skel.l: New file.
 578
 579 2001-12-29  Akim Demaille  <akim@epita.fr>
 580
 581         %name-prefix is broken.
 582
 583         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
 584         Adjust all dependencies.
 585         * tests/headers.at (export YYLTYPE): Strengthen this test: use
 586         %name-prefix.
 587
 588         Renaming yylval but not yylloc is not consistent.  Now we do.
 589
 590         * src/bison.simple: Prefix yylloc if used.
 591         * doc/bison.texinfo (Decl Summary): Document that.
 592
 593 2001-12-29  Akim Demaille  <akim@epita.fr>
 594
 595         * doc/bison.texinfo: Promote `%long-directive' over
 596         `%long_directive'.
 597         Remove all references to fixed-output-files, yacc is enough.
 598
 599 2001-12-29  Akim Demaille  <akim@epita.fr>
 600
 601         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
 602         user prologue.  These are defaults.
 603         * tests/actions.at (Mid-rule actions): Make sure the user can
 604         define YYDEBUG and YYERROR_VERBOSE.
 605
 606 2001-12-29  Akim Demaille  <akim@epita.fr>
 607
 608         * src/output.c (header_output): Don't forget to export YYLTYPE and
 609         yylloc.
 610         * tests/headers.at (export YYLTYPE): New, make sure it does.
 611         * tests/regression.at (%union and --defines, Invalid CPP headers):
 612         Move to...
 613         * tests/headers.at: here.
 614
 615 2001-12-29  Akim Demaille  <akim@epita.fr>
 616
 617         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
 618
 619 2001-12-29  Akim Demaille  <akim@epita.fr>
 620
 621         * tests/actions.at (Mid-rule actions): Output on a single line
 622         instead of several.
 623
 624 2001-12-29  Akim Demaille  <akim@epita.fr>
 625
 626         * doc/bison.texinfo: Formatting changes.
 627
 628 2001-12-29  Akim Demaille  <akim@epita.fr>
 629
 630         Don't store the token defs in a muscle, just be ready to output it
 631         on command.  Now possible via `symbols'.  Fixes a memory leak.
 632
 633         * src/output.c (token_definitions_output): New.
 634         (output_parser, header_output): Use it.
 635         * src/reader.c (symbols_save): Remove.
 636
 637 2001-12-29  Akim Demaille  <akim@epita.fr>
 638
 639         * src/bison.simple: Do not provide a default for YYSTYPE and
 640         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
 641         default.
 642
 643 2001-12-29  Akim Demaille  <akim@epita.fr>
 644
 645         Mid-rule actions are simply... ignored!
 646
 647         * src/reader.c (readgram): Be sure to attach mid-rule actions to
 648         the empty-rule associated to the dummy symbol, not to the host
 649         rule.
 650         * tests/actions.at (Mid-rule actions): New.
 651
 652 2001-12-29  Akim Demaille  <akim@epita.fr>
 653
 654         Memory leak.
 655
 656         * src/reader.c (reader): Free grammar.
 657
 658 2001-12-29  Akim Demaille  <akim@epita.fr>
 659
 660         Memory leak.
 661
 662         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
 663         since it allocates it for each state, although only one is needed.
 664         (allocate_storage): Do it here.
 665
 666 2001-12-29  Akim Demaille  <akim@epita.fr>
 667
 668         * src/options.h, src/options.c (create_long_option_table): Rename
 669         as...
 670         (long_option_table_new): this, with a clearer prototype.
 671         (percent_table): Remove, unused,
 672         * src/getargs.c (getargs): Adjust.
 673
 674 2001-12-29  Akim Demaille  <akim@epita.fr>
 675
 676         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
 677         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 678         as states.
 679
 680 2001-12-29  Akim Demaille  <akim@epita.fr>
 681
 682         * src/lalr.c (build_relations): Rename `states' as `states1'.
 683         Sorry, I don't understand exactly what it is, no better name...
 684
 685 2001-12-29  Akim Demaille  <akim@epita.fr>
 686
 687         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 688         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 689         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 690         as rules.
 691
 692 2001-12-29  Akim Demaille  <akim@epita.fr>
 693
 694         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 695         ago.
 696
 697 2001-12-29  Akim Demaille  <akim@epita.fr>
 698
 699         * src/reader.c, src/reader.h (user_toknums): Remove.
 700         Adjust all users to use symbols[i]->user_token_number.
 701
 702 2001-12-29  Akim Demaille  <akim@epita.fr>
 703
 704         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 705         Adjust all users to use symbols[i]->prec or ->assoc.
 706
 707 2001-12-29  Akim Demaille  <akim@epita.fr>
 708
 709         * src/reader.c, src/reader.h (tags): Remove.
 710         Adjust all users to use symbols[i]->tag.
 711
 712 2001-12-29  Akim Demaille  <akim@epita.fr>
 713
 714         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 715         and rule_table.
 716         * src/reader.c (packsymbols): Fill this table.
 717         Drop sprec.
 718         * src/conflicts.c (resolve_sr_conflict): Adjust.
 719         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 720         single table.
 721         Use symbols[i]->tag instead of tags[i].
 722
 723 2001-12-29  Akim Demaille  <akim@epita.fr>
 724
 725         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 726         In addition, put a comment in there, to replace...
 727         * tests/regression.at (%union and C comments): Remove.
 728
 729 2001-12-29  Akim Demaille  <akim@epita.fr>
 730
 731         * tests/regression.at (Web2c Actions): Blindly move the actual
 732         output as expected output.  The contents *seem* right to me, but I
 733         can't pretend reading perfectly parser tables...  Nonetheless, all
 734         the other tests pass correctly, the table look OK, even though the
 735         presence of `$axiom' is to be noted: AFAICS it is useless (but
 736         harmless).
 737
 738 2001-12-29  Akim Demaille  <akim@epita.fr>
 739
 740         * src/reader.c (readgram): Don't add the rule 0 if there were no
 741         rules read.  In other words, add it _after_ having performed
 742         grammar sanity checks.
 743         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 744
 745 2001-12-29  Akim Demaille  <akim@epita.fr>
 746
 747         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 748         visible, and some states have now a different number.
 749

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

 807
 808 2001-12-29  Akim Demaille  <akim@epita.fr>
 809
 810         * src/output.c: Comment changes.
 811
 812 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 813
 814         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 815         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 816         Sparc, as they were causing more porting problems than the
 817         (minor) performance improvement was worth.
 818
 819         Also, catch up with 1.31's YYSTD.
 820
 821 2001-12-27  Akim Demaille  <akim@epita.fr>
 822
 823         * src/output.c (output_gram): Rely on nritems, not the
 824         0-sentinel.  See below.
 825         Use -1 as separator, not 0.
 826         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 827         Rely on -1 as separator in yyrhs, instead of 0.
 828         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 829         twice `Now at end of input', therefore there are two lines less to
 830         expect.
 831
 832 2001-12-27  Akim Demaille  <akim@epita.fr>
 833
 834         * tests/regression.at (Unresolved SR Conflicts):
 835         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 836         below.
 837
 838 2001-12-27  Akim Demaille  <akim@epita.fr>
 839
 840         * src/LR0.c (new_state): Recognize the final state by the fact it
 841         is reached by eoftoken.
 842         (insert_start_shifting_state, insert_eof_shifting_state)
 843         (insert_accepting_state, augment_automaton): Remove, since now
 844         these states are automatically computed from the initial state.
 845         (generate_states): Adjust.
 846         * src/print.c: When reporting a rule number to the user, substract
 847         1, so that the axiom rule is rule 0, and the first user rule is 1.
 848         * src/reduce.c: Likewise.
 849         * src/print_graph.c (print_core): For the time being, just as for
 850         the report, depend upon --trace-flags to dump the full set of
 851         items.
 852         * src/reader.c (readgram): Once the grammar read, insert the rule
 853         0: `$axiom: START-SYMBOL $'.
 854         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 855         number of the states has changed (the final state is no longer
 856         necessarily the last), catch up.
 857
 858 2001-12-27  Akim Demaille  <akim@epita.fr>
 859
 860         Try to make the use of the eoftoken valid.  Given that its value
 861         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 862         is used instead of > 0 where appropriate, (ii), depend upon nritems
 863         instead of the 0-sentinel.
 864
 865         * src/gram.h, src/gram.c (nritems): New.
 866         Expected to be duplication of nitems, but for the time being...
 867         * src/reader.c (packgram): Assert nritems and nitems are equal.
 868         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 869         * src/closure.c (print_closure, print_fderives): Likewise.
 870         * src/gram.c (ritem_print): Likewise.
 871         * src/print.c (print_core, print_grammar): Likewise.
 872         * src/print_graph.c: Likewise.
 873
 874 2001-12-27  Akim Demaille  <akim@epita.fr>
 875
 876         * src/main.c (main): If there are complains after grammar
 877         reductions, then output the report anyway if requested, then die.
 878         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 879         * src/reader.c (eoftoken): New.
 880         (parse_token_decl): If the token being defined has value `0', it
 881         is the eoftoken.
 882         (packsymbols): No longer hack `tags' to insert `$' by hand.
 883         Be sure to preserve the value of the eoftoken.
 884         (reader): Make sure eoftoken is defined.
 885         Initialize nsyms to 0: now eoftoken is created just like the others.
 886         * src/print.c (print_grammar): Don't special case the eof token.
 887         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 888         lie anyway, albeit pleasant.
 889         * tests/calc.at: Exercise error messages with eoftoken.
 890         Change the grammar so that empty input is invalid.
 891         Adjust expectations.
 892         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 893
 894 2001-12-27  Akim Demaille  <akim@epita.fr>
 895
 896         * configure.in: Check the protos of strchr ans strspn.
 897         Replace strchr if needed.
 898         * src/system.h: Provide the protos of strchr, strspn and memchr if
 899         missing.
 900         * lib/strchr.c: New.
 901         * src/reader.c (symbols_save): Use strchr.
 902
 903 2001-12-27  Akim Demaille  <akim@epita.fr>
 904
 905         * src/print.c, src/print_graph.c (escape): New.
 906         Use it to quote the TAGS outputs.
 907         * src/print_graph.c (print_state): Now errors are in red, and
 908         reductions in green.
 909         Prefer high to wide: output the state number on a line of its own.
 910
 911 2001-12-27  Akim Demaille  <akim@epita.fr>
 912
 913         * src/state.h, src/state.c (reductions_new): New.
 914         * src/LR0.c (set_state_table): Let all the states have a
 915         `reductions', even if reduced to 0.
 916         (save_reductions): Adjust.
 917         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 918         * src/print.c (print_reductions, print_actions): Adjust.
 919         * src/output.c (action_row): Adjust.
 920
 921 2001-12-27  Akim Demaille  <akim@epita.fr>
 922
 923         * src/state.h, src/state.c (errs_new, errs_dup): New.
 924         * src/LR0.c (set_state_table): Let all the states have an errs,
 925         even if reduced to 0.
 926         * src/print.c (print_errs, print_reductions): Adjust.
 927         * src/output.c (output_actions, action_row): Adjust.
 928         * src/conflicts.c (resolve_sr_conflict): Adjust.
 929
 930 2001-12-27  Akim Demaille  <akim@epita.fr>
 931
 932         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 933
 934 2001-12-27  Akim Demaille  <akim@epita.fr>
 935
 936         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 937         * src/print.c: here.
 938         (lookaheadset, shiftset): New, used as additional storage by
 939         print_reductions.
 940         (print_results): Adjust.
 941         (print_shifts, print_gotos, print_errs): New, extracted from...
 942         (print_actions): here.
 943         * src/print_graph.c (print_actions): Remove dead code.
 944
 945 2001-12-27  Akim Demaille  <akim@epita.fr>
 946
 947         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 948         `$n' and `@n'.
 949
 950 2001-12-27  Akim Demaille  <akim@epita.fr>
 951
 952         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 953         (build_relations): Adjust.
 954
 955 2001-12-27  Akim Demaille  <akim@epita.fr>
 956
 957         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 958         duplication.
 959
 960 2001-12-27  Akim Demaille  <akim@epita.fr>
 961
 962         * src/reader.c (packgram): Catch nitems overflows.
 963
 964 2001-12-27  Akim Demaille  <akim@epita.fr>
 965
 966         * src/files.c, src/files.h (guard_obstack): Remove.
 967         * src/output.c (output): Adjust.
 968         * src/reader.c (parse_braces): New, factoring...
 969         (copy_action, copy_guard): these two which are renamed as...
 970         (parse_action, parse_guard): these.
 971         As a voluntary consequence, using braces around guards is now
 972         mandatory.
 973
 974 2001-12-27  Akim Demaille  <akim@epita.fr>
 975
 976         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 977         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 978         members.
 979         (symbol_list_new): Adjust.
 980         (copy_action): action_line is the first line, not the last.
 981         (copy_guard): Just as for actions, store the `action' only, not
 982         the switch/case/break flesh.
 983         Don't parse the user action that might follow the guard, let...
 984         (readgram): do it, i.e., now, there can be an action after a
 985         guard.
 986         In other words the guard is just explicitly optional.
 987         (packgram): Adjust.
 988         * src/output.c (guards_output): New.
 989         (output_parser): Call it when needed.
 990         (output): Also free the guard and attrs obstacks.
 991         * src/files.c, src/files.h (obstack_save): Remove.
 992         (output_files): Remove.
 993         As a result, if one needs the former `.act' file, using an
 994         appropriate skeleton which requires actions and guards is now
 995         required.
 996         * src/main.c (main): Adjust.
 997         * tests/semantic.at: New.
 998         * tests/regression.at: Use `input.y' as input file name.
 999         Avoid 8+3 problems by requiring input.c when the test needs the
1000         parser.
1001
1002 2001-12-27  Akim Demaille  <akim@epita.fr>
1003
1004         * src/reader.c (symbol_list_new): Be sure to initialize all the
1005         fields.
1006
1007 2001-12-27  Akim Demaille  <akim@epita.fr>
1008
1009         All the hacks using a final pseudo state are now useless.
1010
1011         * src/LR0.c (set_state_table): state_table holds exactly nstates.
1012         * src/lalr.c (nLA): New.
1013         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
1014         instead of lookaheadsp from the pseudo state (nstate + 1).
1015
1016 2001-12-27  Akim Demaille  <akim@epita.fr>
1017
1018         * src/output.c (action_row, token_actions): Use a state_t instead
1019         of a integer, and nlookaheads instead of the following state's
1020         lookaheadsp.
1021
1022 2001-12-27  Akim Demaille  <akim@epita.fr>
1023
1024         * src/conflicts.c (log_resolution, flush_shift)
1025         (resolve_sr_conflict, set_conflicts, solve_conflicts)
1026         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
1027         (conflicts_print, print_reductions): Use a state_t instead of an
1028         integer when referring to a state.
1029         As much as possible, depend upon nlookaheads, instead of the
1030         `lookaheadsp' member of the following state (since lookaheads of
1031         successive states are successive, the difference between state n + 1
1032         and n served as the number of lookaheads for state n).
1033         * src/lalr.c (add_lookback_edge): Likewise.
1034         * src/print.c (print_core, print_actions, print_state)
1035         (print_results): Likewise.
1036         * src/print_graph.c (print_core, print_actions, print_state)
1037         (print_graph): Likewise.
1038         * src/conflicts.h: Adjust.
1039
1040 2001-12-27  Akim Demaille  <akim@epita.fr>
1041
1042         * src/bison.hairy: Formatting/comment changes.
1043         ANSIfy.
1044         Remove `register' indications.
1045         Add plenty of `static'.
1046
1047 2001-12-27  Akim Demaille  <akim@epita.fr>
1048
1049         * src/output.c (prepare): Drop the muscle `ntbase' which
1050         duplicates ntokens.
1051         * src/bison.simple: Formatting/comment changes.
1052         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
1053         is an undocumented synonym.
1054
1055 2001-12-22  Akim Demaille  <akim@epita.fr>
1056
1057         * src/output.c (output_table_data): Change the prototype to use
1058         `int' for array ranges: some invocations do pass an int, not a
1059         short.
1060         Reported by Wayne Green.

1064         Some actions of web2c.y are improperly triggered.
1065         Reported by Mike Castle.
1066
1067         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
1068         * tests/regression.at (Web2c): Rename as...
1069         (Web2c Report): this.
1070         (Web2c Actions): New.
1071
1072 2001-12-22  Akim Demaille  <akim@epita.fr>
1073
1074         Reductions in web2c.y are improperly reported.
1075         Reported by Mike Castle.
1076
1077         * src/conflicts.c (print_reductions): Fix.
1078         * tests/regression.at (Web2c): New.
1079
1080 2001-12-18  Akim Demaille  <akim@epita.fr>
1081
1082         Some host fail on `assert (!"foo")', which expands to
1083         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
1084         Reported by Nelson Beebee.
1085
1086         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
1087         `#define it_succeeded 0' and `assert (it_succeeded)'.
1088
1089 2001-12-17  Marc Autret  <autret_m@epita.fr>
1090
1091         * src/bison.simple: Don't hard code the skeleton line and filename.
1092         * src/output.c (output_parser): Rename 'line' as 'output_line'.
1093         New line counter 'skeleton_line' (skeleton-line muscle).
1094
1095 2001-12-17  Paul Eggert  <eggert@twinsun.com>
1096
1097         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
1098         YYDEBUG must be defined to a nonzero value.
1099
1100         * src/bison.simple (yytname): Do not assume that the user defines
1101         YYDEBUG to a properly parenthesized expression.
1102
1103 2001-12-17  Akim Demaille  <akim@epita.fr>
1104
1105         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
1106         nlookaheads is a new member.
1107         Adjust all users.
1108         * src/lalr.h (nlookaheads): Remove this orphan declaration.
1109         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
1110         state.
1111
1112 2001-12-17  Akim Demaille  <akim@epita.fr>
1113
1114         * src/files.h, src/files.c (open_files, close_files): Remove.
1115         * src/main.c (main): Don't open/close files, nor invoke lex_free,
1116         let...
1117         * src/reader.c (reader): Do it.
1118
1119 2001-12-17  Akim Demaille  <akim@epita.fr>
1120
1121         * src/conflicts.c (print_reductions): Formatting changes.
1122
1123 2001-12-17  Akim Demaille  <akim@epita.fr>
1124
1125         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
1126         (flush_reduce): New.
1127         (resolve_sr_conflict): Adjust.
1128
1129 2001-12-17  Akim Demaille  <akim@epita.fr>
1130
1131         * src/output.c (output_obstack): Be static and rename as...
1132         (format_obstack): this, to avoid any confusion with files.c's
1133         output_obstack.
1134         * src/reader.h (muscle_obstack): Move to...
1135         * src/output.h: here, since it's defined in output.c.
1136
1137 2001-12-17  Akim Demaille  <akim@epita.fr>
1138
1139         * src/output.c (action_row, save_column, default_goto)
1140         (sort_actions, matching_state, pack_vector): Better variable
1141         locality.
1142
1143 2001-12-17  Akim Demaille  <akim@epita.fr>
1144
1145         * src/output.c: Various formatting changes.
1146
1147 2001-12-17  Akim Demaille  <akim@epita.fr>
1148
1149         * src/files.c (output_files): Free the output_obstack.
1150         * src/main.c (main): Call print and print_graph conditionally.
1151         * src/print.c (print): Work unconditionally.
1152         * src/print_graph.c (print_graph): Work unconditionally.
1153         * src/conflicts.c (log_resolution): Output only if verbose_flag.
1154
1155 2001-12-16  Marc Autret  <autret_m@epita.fr>
1156
1157         * src/output.c (actions_output): Fix. When we use %no-lines,
1158         there is one less line per action.
1159
1160 2001-12-16  Marc Autret  <autret_m@epita.fr>
1161
1162         * src/bison.simple: Remove a useless #line directive.
1163         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1164         * src/output.c (get_lines_number): New.
1165         (output_parser): Adjust, now takes care about the lines of a
1166         output muscles.
1167         Fix line numbering.
1168         (actions_output): Computes the number of lines taken by actions.
1169         (output_master_parser): Insert new skeleton which is the name of
1170         the output parser file name.
1171
1172 2001-12-15  Marc Autret  <autret_m@epita.fr>
1173
1174         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
1175
1176 2001-12-15  Marc Autret  <autret_m@epita.fr>
1177
1178         * src/output.c (output_gram): Keep track of the hairy one.
1179
1180 2001-12-15  Akim Demaille  <akim@epita.fr>
1181
1182         Make `make distcheck' work.
1183
1184         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1185         system.h which uses libgettext.h.
1186
1187 2001-12-15  Akim Demaille  <akim@epita.fr>
1188
1189         * src/nullable.c (set_nullable): Useless rules must be skipped,
1190         otherwise, since we range over their symbols, we might look at a
1191         nonterminal which no longer ``exists'', i.e., it is not counted in
1192         `nvars', hence we overflow our arrays.
1193
1194 2001-12-15  Akim Demaille  <akim@epita.fr>
1195
1196         The header can also be produced directly, without any obstack!
1197         Yahoo!
1198
1199         * src/files.c, src/files.h (defines_obstack): Remove.
1200         (compute_header_macro): Global.
1201         (defines_obstack_save): Remove.
1202         * src/reader.c (parse_union_decl): No longer output to
1203         defines_obstack: its content can be found in the `stype' muscle
1204         anyway.
1205         (output_token_translations): Merge into...
1206         (symbols_output): this.
1207         Rename as...
1208         (symbols_save): this.
1209         (reader): Adjust.
1210         * src/output.c (header_output): New.
1211         (output): Call it.
1212
1213 2001-12-15  Akim Demaille  <akim@epita.fr>
1214
1215         * src/reader.c (parse_union_decl): Instead of handling two obstack
1216         simultaneously, use one to define the `stype' muscle, and use the
1217         value of the latter to fill defines_obstack.
1218         (copy_comment): Remove.
1219         (copy_comment2): Work for a single obstack.
1220         Rename as...
1221         (copy_comment): this.
1222
1223 2001-12-15  Akim Demaille  <akim@epita.fr>
1224
1225         * src/lex.c, src/lex.h (xgetc): No longer static.
1226         * src/reader.c (parse_union_decl): Revamp.
1227
1228 2001-12-15  Akim Demaille  <akim@epita.fr>
1229
1230         Still making progress in separating Bison into (i) input, (ii)
1231         process, (iii) output: now we can directly output the parser file
1232         without using table_obstack at all.
1233
1234         * src/files.c, src/files.h (table_obstack): Bye bye.
1235         (parser_file_name): New.
1236         * src/files.c (compute_output_file_names): Compute it.
1237         * src/output.c (actions_output, output_parser)
1238         (output_master_parser): To a file instead of an obstack.
1239
1240 2001-12-15  Akim Demaille  <akim@epita.fr>
1241
1242         Attach actions to rules, instead of pre-outputting them to
1243         actions_obstack.
1244
1245         * src/gram.h (rule_t): action and action_line are new members.
1246         * src/reader.c (symbol_list): Likewise.
1247         (copy_action): Save the actions within the rule.
1248         (packgram): Save them in rule_table.
1249         * src/output.c (actions_output): New.
1250         (output_parser): Use it on `%%actions'.
1251         (output_rule_data): Don't free rule_table.
1252         (output): Do it.
1253         (prepare): Don't save the `action' muscle.
1254         * src/bison.simple: s/%%action/%%actions/.
1255
1256 2001-12-15  Akim Demaille  <akim@epita.fr>
1257
1258         * src/reader.c (copy_action): When --yacc, don't append a `;'
1259         to the user action: let it fail if lacking.
1260         Suggested by Arnold Robbins and Tom Tromey.
1261
1262 2001-12-14  Akim Demaille  <akim@epita.fr>
1263
1264         * src/lex.c (literalchar): Simply return the char you decoded, non
1265         longer mess around with obstacks and int pointers.
1266         Adjust all callers.
1267
1268 2001-12-14  Akim Demaille  <akim@epita.fr>
1269
1270         * src/lex.c (literalchar): Don't escape the special characters,
1271         just decode them, and keep them as char (before, eol was output as
1272         the 2 char string `\n' etc.).
1273         * src/output.c (output_rule_data): Use quotearg to output the
1274         token strings.
1275
1276 2001-12-13  Paul Eggert  <eggert@twinsun.com>
1277
1278         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1279         Do not infringe on the global user namespace when using C++.
1280         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1281         All uses of `fprintf' and `stderr' changed.
1282
1283         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1284
1285 2001-12-13  Akim Demaille  <akim@epita.fr>
1286
1287         The computation of nullable is broken: it doesn't handle empty
1288         RHS's properly.
1289
1290         * tests/torture.at (GNU AWK Grammar): New.
1291         * tests/sets.at (Nullable): New.
1292         * src/nullable.c (set_nullable): Instead of blindly looping over
1293         `ritems', loop over the rules, and then over their rhs's.
1294
1295         Work around Autotest bugs.
1296
1297         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1298         frame, because Autotest understand lines starting with a `+' as
1299         traces from the shell.  Then, they are not processed properly.
1300         Admittedly an Autotest bug, but we don't have time to wait for
1301         Autotest to catch up.
1302         * tests/regression.at (Broken Closure): Adjust to the new table
1303         frames.
1304         Move to...
1305         * tests/sets.at: here.
1306
1307 2001-12-13  Akim Demaille  <akim@epita.fr>
1308
1309         * src/closure.c (closure): Use nrules instead of playing tricks
1310         with BITS_PER_WORD.
1311
1312 2001-12-13  Akim Demaille  <akim@epita.fr>
1313
1314         * src/print.c (print_actions): Output the handling of `$' as the
1315         traces do: shifting the token EOF.  Before EOF was treated as a
1316         nonterminal.
1317         * tests/regression.at: Adjust some tests.
1318         * src/print_graph.c (print_core): Complete the set of items via
1319         closure.  The next-to-final and final states are still unsatisfying,
1320         but that's to be addressed elsewhere.
1321         No longer output the rule numbers, but do output the state number.
1322         A single loop for the shifts + gotos is enough, but picked a
1323         distinct color for each.
1324         (print_graph): Initialize and finalize closure.
1325
1326 2001-12-13  Akim Demaille  <akim@epita.fr>
1327
1328         * src/reader.c (readgram): Remove dead code, an strip useless
1329         braces.
1330         (get_type): Remove, unused.
1331
1332 2001-12-12  Akim Demaille  <akim@epita.fr>
1333
1334         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1335         on that of lib/error.c.
1336
1337 2001-12-12  Akim Demaille  <akim@epita.fr>
1338
1339         Some hosts don't like `/' in includes.
1340
1341         * src/system.h: Include libgettext.h without qualifying the path.
1342         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1343         $(top_srcdir).
1344
1345 2001-12-11  Marc Autret  <autret_m@epita.fr>
1346
1347         * src/output.c (output_parser): Remove useless muscle.
1348
1349 2001-12-11  Marc Autret  <autret_m@epita.fr>
1350
1351         * src/bison.simple: Remove #line just before %%epilogue. It
1352         is now handled in ...
1353         * src/reader.c (read_additionnal_code): Add the output of a
1354         #line for the epilogue.
1355
1356 2001-12-10  Marc Autret  <autret_m@epita.fr>
1357
1358         * src/reader.c (copy_definition): Re-use CPP-outed code which
1359         replace precedent remove.
1360         * src/bison.simple: Remove #line before %%prologue because
1361         %%input-line is wrong at this time.
1362
1363 2001-12-10  Marc Autret  <autret_m@epita.fr>
1364
1365         * src/reader.c (symbols_output): Clean up.
1366         * src/output.c (output_gram, output): Clean up.
1367
1368 2001-12-10  Akim Demaille  <akim@epita.fr>
1369
1370         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
1371         * src/LR0.c (set_state_table): here.
1372         * src/lalr.c (lalr): Call it.
1373
1374 2001-12-10  Akim Demaille  <akim@epita.fr>
1375
1376         * src/state.h (shifts): Remove the `number' member: shifts are
1377         attached to state, hence no longer need to be labelled with a
1378         state number.
1379
1380 2001-12-10  Akim Demaille  <akim@epita.fr>
1381
1382         Now that states have a complete set of members, the linked list of
1383         shifts is useless: just fill directly the state's shifts member.
1384
1385         * src/state.h (shifts): Remove the `next' member.
1386         * src/LR0.c (first_state, last_state): Remove.
1387         Adjust the callers.
1388         (augment_automaton): Don't look for the shifts that must be added
1389         a shift on EOF: it is those of the state we looked for!  But now,
1390         since shifts are attached, it is no longer needed to looking
1391         merely by its id: its number.
1392
1393 2001-12-10  Akim Demaille  <akim@epita.fr>
1394
1395         * src/LR0.c (augment_automaton): Better variable locality.
1396         Remove an impossible branch: if there is a state corresponding to
1397         the start symbol being shifted, then there is shift for the start
1398         symbol from the initial state.
1399
1400 2001-12-10  Akim Demaille  <akim@epita.fr>
1401
1402         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1403         only when appropriate: when insert_start_shifting_state' is not
1404         invoked.
1405         * tests/regression.at (Rule Line Numbers): Adjust.
1406
1407 2001-12-10  Akim Demaille  <akim@epita.fr>
1408
1409         * src/LR0.c (augment_automaton): Now that all states have shifts,
1410         merge the two cases addition shifts to the initial state.
1411
1412 2001-12-10  Akim Demaille  <akim@epita.fr>
1413
1414         * src/lalr.c (set_state_table): Move to...
1415         * src/LR0.c: here.
1416         * src/lalr.c (lalr): Don't call it...
1417         * src/LR0.c (generate_states): do it.
1418         * src/LR0.h (first_state): Remove, only the table is used.
1419
1420 2001-12-10  Akim Demaille  <akim@epita.fr>
1421
1422         * src/LR0.h (first_shift, first_reduction): Remove.
1423         * src/lalr.c: Don't use first_shift: find shifts through the
1424         states.
1425
1426 2001-12-10  Akim Demaille  <akim@epita.fr>
1427
1428         * src/LR0.c: Attach shifts to states as soon as they are
1429         computed.
1430         * src/lalr.c (set_state_table): Instead of assigning shifts to
1431         state, just assert that the mapping was properly done.
1432
1433 2001-12-10  Akim Demaille  <akim@epita.fr>
1434
1435         * src/LR0.c (insert_start_shift): Rename as...
1436         (insert_start_shifting_state): this.
1437         (insert_eof_shifting_state, insert_accepting_state): New.
1438         (augment_automaton): Adjust.
1439         Better locality of the variables.
1440         When looking if the start_symbol is shifted from the initial
1441         state, using `while (... symbol != start_symbol ...)' sounds
1442         better than `while (... symbol < start_symbol ...)': If fail
1443         to see how the order between symbols could be relevant!
1444
1445 2001-12-10  Akim Demaille  <akim@epita.fr>
1446
1447         * src/getargs.h: Don't declare `spec_name_prefix' and
1448         `spec_file_prefix', declared by src/files.h.
1449         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1450         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1451         * src/output.c (prepare): Adjust.
1452         * src/reader.c (symbols_output): Likewise.
1453         * src/vmsgetargs.c: Vaguely adjust, but who cares?
1454

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

1532
1533         Bison dumps core on bash.y.
1534         Reported by Pascal Bart.
1535
1536         * src/warshall.c (bitmatrix_print): New.
1537         (TC): Use it.
1538         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1539         j must be the outer loop.
1540         * tests/regression.at (Broken Closure): New.
1541
1542 2001-12-05  Akim Demaille  <akim@epita.fr>
1543
1544         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1545         its argument.
1546         Reported by Peter Hámorský.
1547
1548 2001-12-05  Akim Demaille  <akim@epita.fr>
1549
1550         * src/conflicts.c (err_table): Remove.
1551         (resolve_sr_conflict): Adjust.
1552         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1553         Rename as...
1554         (state_t.reductions, state_t.shifts): this.
1555
1556 2001-12-05  Akim Demaille  <akim@epita.fr>
1557
1558         * src/reduce.c (reduce_grammar_tables): No longer disable the
1559         removal of useless rules via CPP but via `if (0)', so that the
1560         compiler still check the code is valid.
1561         For instance, it should have noticed `rline' no longer exists: use
1562         the `line' member of rule_t.
1563         * src/gram.c (dummy, rline): Remove, unused.
1564
1565 2001-12-05  Akim Demaille  <akim@epita.fr>
1566
1567         * src/output.c (pack_vector): Use assert, not berror.
1568         * src/main.c (berror): Remove, unused.
1569
1570 2001-12-05  Akim Demaille  <akim@epita.fr>
1571
1572         New experimental feature: if --verbose --trace output all the
1573         items of a state, not only its kernel.
1574
1575         * src/print.c (print_core): If `trace_flag', then invoke closure
1576         before outputting the items of the state (print_core is no longer
1577         a correct name them).
1578         (print_results): Invoke new_closure/free_closure if needed.
1579
1580 2001-12-05  Akim Demaille  <akim@epita.fr>
1581
1582         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1583         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1584         (nitemset): for consistency with the rest of the project.
1585
1586 2001-12-05  Akim Demaille  <akim@epita.fr>
1587
1588         * src/closure.c (print_closure): Improve.
1589         (closure): Use it for printing input and output.
1590
1591 2001-12-05  Akim Demaille  <akim@epita.fr>
1592
1593         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1594         indexed by nonterminals.
1595
1596 2001-12-05  Akim Demaille  <akim@epita.fr>
1597
1598         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1599         what it was!).
1600         * src/warshall.h: Remove accidental duplication of the content.
1601
1602 2001-12-05  Akim Demaille  <akim@epita.fr>
1603
1604         * src/closure.c (set_fderives): De-obfuscate.
1605
1606 2001-12-05  Akim Demaille  <akim@epita.fr>
1607

1613
1614 2001-12-05  Akim Demaille  <akim@epita.fr>
1615
1616         * src/output.c (action_row): De-obfuscate
1617         using the good o' techniques: arrays not pointers, variable
1618         locality, BITISSET, RESETBIT etc.
1619
1620 2001-12-05  Akim Demaille  <akim@epita.fr>
1621
1622         Pessimize the code to simplify it: from now on, all the states
1623         have a valid SHIFTS, which NSHIFTS is possibly 0.
1624
1625         * src/LR0.c (shifts_new): Be global and move to..
1626         * src/state.c, src/state.h: here.
1627         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1628         * src/print_graph: Adjust.
1629
1630 2001-12-05  Akim Demaille  <akim@epita.fr>
1631
1632         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1633         * src/conflicts.c: Use it.
1634         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1635         incorrectly ``simplified''.
1636
1637 2001-12-05  Akim Demaille  <akim@epita.fr>
1638
1639         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1640         using the good o' techniques: arrays not pointers, variable
1641         locality, BITISSET, RESETBIT etc.
1642
1643 2001-12-05  Akim Demaille  <akim@epita.fr>
1644
1645         * src/state.h (SHIFT_SYMBOL): New.
1646         * src/conflicts.c: Use it to deobfuscate.
1647
1648 2001-12-05  Akim Demaille  <akim@epita.fr>
1649
1650         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1651         (print_reductions): De-obfuscate using the good o' techniques:
1652         arrays not pointers, variable locality, BITISSET.
1653
1654 2001-12-05  Akim Demaille  <akim@epita.fr>
1655
1656         * src/conflicts.c (print_reductions): Arrays, not pointers.
1657         Use BITISSET.
1658
1659 2001-12-05  Akim Demaille  <akim@epita.fr>
1660
1661         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1662
1663 2001-12-05  Akim Demaille  <akim@epita.fr>
1664
1665         * src/conflicts.c (print_reductions): Improve variable locality.

1668
1669         * src/conflicts.c (print_reductions): Pessimize, but clarify.

1674
1675 2001-12-05  Akim Demaille  <akim@epita.fr>
1676
1677         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
1678         * src/lalr.c: Use them.
1679
1680 2001-12-05  Akim Demaille  <akim@epita.fr>
1681
1682         * src/LR0.c (augment_automaton): Formatting changes.
1683         Better variable locality.
1684
1685 2001-12-05  Akim Demaille  <akim@epita.fr>
1686
1687         * src/lalr.c (matrix_print): New.
1688         (transpose): Use it.
1689         Use arrays instead of pointers.
1690
1691 2001-12-05  Akim Demaille  <akim@epita.fr>
1692
1693         * src/lalr.c (maxrhs): Move to...
1694         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1695         * src/lalr.c (build_relations): Adjust.
1696
1697 2001-12-05  Akim Demaille  <akim@epita.fr>
1698
1699         * src/lalr.c (transpose): Free the memory allocated to the
1700         argument, as it is replaced by the results by the unique caller.
1701         (build_relations): Merely invoke transpose: it handles the memory
1702         deallocation.
1703         Improve variable locality.
1704         Avoid variables used as mere abbreviations.
1705         (compute_lookaheads): Use arrays instead of pointers.
1706
1707 2001-12-05  Akim Demaille  <akim@epita.fr>
1708
1709         * src/lalr.c (initialize_F): Improve variable locality.
1710         Avoid variables used as mere abbreviations.
1711
1712 2001-12-05  Akim Demaille  <akim@epita.fr>
1713
1714         * src/derives.c (print_derives): Display the ruleno.
1715         * src/lalr.c (initialize_F, transpose): Better variable locality
1716         to improve readability.
1717         Avoid variables used as mere abbreviations.
1718
1719 2001-12-05  Akim Demaille  <akim@epita.fr>
1720
1721         * src/lalr.c (traverse): Use arrays instead of pointers.
1722
1723 2001-12-05  Akim Demaille  <akim@epita.fr>
1724
1725         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1726         the handling of squeue.
1727         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1728
1729 2001-12-05  Akim Demaille  <akim@epita.fr>
1730
1731         Because useless nonterminals are now kept alive (instead of being
1732         `destroyed'), we now sometimes examine them, and store information
1733         related to them.  Hence we need to know their number, and adjust
1734         memory allocations.
1735
1736         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1737         static.
1738         * src/LR0.c (allocate_itemsets): The memory allocated to
1739         `symbol_count' was used for two different purpose: once to count
1740         the number of occurrences of each symbol, and later reassigned to
1741         `shift_symbol', containing the symbol that can be shifted from a
1742         given state.
1743         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1744         only, and...
1745         (new_itemsets): Allocate `shift_symbol' here.
1746         (allocate_itemsets): symbol_count includes useless nonterminals.
1747         Make room for them.
1748         (free_storage): Use `free', not `XFREE', for pointers that cannot
1749         be null.
1750
1751 2001-12-05  Akim Demaille  <akim@epita.fr>
1752
1753         * src/nullable.c (set_nullable): Deobfuscate the handling of
1754         ritem.
1755         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1756
1757 2001-12-05  Akim Demaille  <akim@epita.fr>
1758
1759         * src/gram.c, src/gram.h (ritem_print): New.
1760         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1761         (This useless function was defined only to work around VMS linkers
1762         that can't handle compilation units with variables only).
1763         * src/reduce.c (dump_grammar): Use it to trace the construction of
1764         ritem.
1765
1766 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1767
1768         * src/bison.simple (union yyalloc): Change member names
1769         to be the same as the stack names.
1770         (yyparse): yyptr is now union yyalloc *, not char *.
1771         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1772         and may generate better code on some machines.
1773         (yystpcpy): Use prototype if __STDC__ is defined, not just
1774         if __cplusplus is defined.
1775
1776 2001-11-30  Akim Demaille  <akim@epita.fr>
1777
1778         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1779         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1780         Gettext doesn't compile cleanly, and dies with -Werror.
1781         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1782         Include WARNING_CFLAGS here.
1783         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1784         before being defined.
1785
1786 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1787
1788         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1789         First arg is int, not unsigned.
1790         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1791         (SIZE_MAX, UINT_MAX): New macros.
1792         (quotearg_n_options): Abort if N is negative.
1793         Avoid overflow check on hosts where size_t is 64 bits and int
1794         is 32 bits, as overflow is impossible there.
1795         Fix off-by-one typo that caused unnecessary reallocation.
1796
1797 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1798
1799         Name space cleanup in generated parser.
1800
1801         * doc/bison.texinfo (Bison Parser): Discuss system headers
1802         and their effect on the user name space.
1803
1804         * src/bison.simple:
1805         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1806         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1807         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1808
1809         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1810         on user names when possible.
1811

1889         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1890         an arbitrary restriction on hosts where size_t is wider than int.
1891
1892         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1893         a parser stack overflow.  Allocate just one block of memory for all
1894         three stacks, instead of allocating three blocks; this typically is
1895         faster and reduces fragmentation.
1896
1897         Do not limit the number of items in the stack to a value that fits
1898         in 'int', as this is an arbitrary limit on hosts with 64-bit
1899         size_t and 32-bit int.

1960
1961         * src/closure.c (closure): No longer optimize the special case

2197         * src/derives.c: Likewise.
2198         * src/reduce.c: (inaccessable_symbols): Using if is better style

2227
2228         * src/vcg.c: You do the output, so you are responsible of the

2231         (print_actions): Don't output the actions as part of the nodes,

2326         * tests/calc.at, tests/output.at, tests/regression.at,
2327         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
2328         now the tests are run in private dirs, therefore AC_CLEANUP and
2329         family can be simplified to 0-ary.
2330         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
2331         use abs. path to find config.h.
2332         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

2356         arg_offset.
2357         arg is const.

3278
3279         * src/bison.simple (yyparse): Don't take the address of an

3289         completely wrong.

3327         (copy_string): Be a simple call to copy_string2 with the last argument
3328         bound to true.
3329         (read_declarations): Add case for macro definition.
3330         (copy_identifier): New.
3331         (parse_macro_decl): Read macro identifiers using copy_identifier

3366         with something new. Skeletons are now processed character by character

3368         first step in making Bison's output process (a lot) more flexible.
3369         (output_parser): Use the macro table.

3697
3698         * src/reader.c (gensym): `gensym_count' is your own.
3699         Use a static buf to create the symbol name, as token_buffer is no
3700         longer a buffer.
3701
3702 2001-02-08  Akim Demaille  <akim@epita.fr>
3703
3704         * src/conflicts.c (conflict_report): Be sure not to append to res
3705         between two calls, which could happen if both first sprintf were

3711         New, from fileutils 4.0.37.
3712         * configure.in: Require Autoconf 2.49c.  I took some time before
3713         making this decision.  This is the only way out for portability
3714         issues in Bison, it would mean way too much duplicate effort to
3715         import in Bison features implemented in 2.49c since 2.13.
3716         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

3724
3725         Get rid of the ad hoc handling of token_buffer in the scanner: use
3726         the obstacks.
3727
3728         * src/lex.c (token_obstack): New.
3729         (init_lex): Initialize it.  No longer call...
3730         (grow_token_buffer): this.  Remove it.
3731         Adjust all the places which used it to use the obstack.
3732

3734
3735         * src/lex.h: Rename all the tokens:
3736         s/\bENDFILE\b/tok_eof/g;
3737         s/\bIDENTIFIER\b/tok_identifier/g;
3738         etc.
3739         Let them be enums, not #define, to ease debugging.
3740         Adjust all the code.
3741
3742 2001-01-18  Akim Demaille  <akim@epita.fr>
3743
3744         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
3745         * src/lex.c (maxtoken, grow_token_buffer): Static.
3746
3747 2001-01-18  Akim Demaille  <akim@epita.fr>
3748
3749         Since we now use obstacks, more % directives can be enabled.
3750
3751         * src/lex.c (percent_table): Also accept `%yacc',
3752         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3753         `%debug'.
3754         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3755         instead of returning a token.
3756         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3757         * src/reader.c (read_declarations): Adjust.
3758         * src/files.c (open_files): Don't call `compute_base_names', don't
3759         compute `attrsfile' since they depend upon data which might be
3760         *in* the input file now.
3761         (output_files): Do it here.
3762         * src/output.c (output_headers): Document the fact that this patch
3763         introduces a guaranteed SEGV for semantic parsers.
3764         * doc/bison.texinfo: Document them.
3765         * tests/suite.at: Exercise these %options.
3766
3767 2000-12-20  Akim Demaille  <akim@epita.fr>
3768
3769         Also handle the output file (--verbose) with obstacks.
3770
3771         * files.c (foutput): Remove.
3772         (output_obstack): New.
3773         Adjust all dependencies.
3774         * src/conflicts.c: Return a string.
3775         * src/system.h (obstack_grow_string): Rename as...
3776         (obstack_sgrow): this.  Be ready to work with non literals.
3777         (obstack_fgrow4): New.
3778

3780
3781         * src/files.c (open_files): Fix the computation of short_base_name
3782         in the case of `-o foo.tab.c'.
3783
3784 2000-12-20  Akim Demaille  <akim@epita.fr>
3785
3786         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
3787         (copy_dollar): Now that everything uses obstacks, get rid of the
3788         FILE * parameters.
3789
3790 2000-12-20  Akim Demaille  <akim@epita.fr>
3791
3792         * src/files.c (open_files): Actually the `.output' file is based
3793         on the short_base_name, not base_name.
3794         * tests/suite.at (Checking output file names): Adjust.
3795
3796 2000-12-20  Akim Demaille  <akim@epita.fr>
3797
3798         * src/bison.s1: Remove, we now use directly...
3799         * src/bison.simple: this.
3800         * src/Makefile.am: Use pkgdata instead of data.
3801

3815         (output_files): Adjust.
3816         (base_name, short_base_name): Be global.
3817         Adjust dependencies.
3818
3819 2000-12-19  Akim Demaille  <akim@epita.fr>
3820
3821         * src/files.c (strsuffix): New.
3822         (stringappend): Be just like strcat but allocate.
3823         (base_names): Eve out from open_files.
3824         Try to simplify the rather hairy computation of base_name and
3825         short_base_name.
3826         (open_files): Use it.
3827         * tests/suite.at (Checking output file names): New test.

3834         `$'.
3835         * src/bison.s1: s/$/%% actions/.
3836         * src/bison.hairy: Likewise.
3837
3838 2000-12-19  Akim Demaille  <akim@epita.fr>
3839
3840         * src/output.c (output_parser): Compute the `#line' lines when
3841         there are.
3842         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
3843         Suggested by Hans Aberg.
3844
3845 2000-12-19  Akim Demaille  <akim@epita.fr>
3846
3847         Let the handling of the skeleton files be local to the procedures
3848         that use it.
3849
3850         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No

3864
3865 2000-12-19  Akim Demaille  <akim@epita.fr>
3866
3867         * src/files.c (open_files): Yipee!  We no longer need all the code
3868         looking for `/tmp' since we have no tmp file.
3869
3870 2000-12-19  Akim Demaille  <akim@epita.fr>
3871
3872         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

3882         `timestamp' and `text' in the default YYLTYPE.

3885
3886         * src/reader.c (copy_definition, parse_union_decl, copy_action)
3887         (copy_guard): Quote the file names.
3888         Reported by Laurent Mascherpa.

3897 2000-11-17  Akim Demaille  <akim@epita.fr>
3898
3899         * lib/obstack.h: Formatting changes.
3900         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3901         prevents type checking.
3902         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3903         cast the value to (void *): assigning a `foo *' to a `void *'
3904         variable is valid.
3905         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3906         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

3939         defining.
3940         * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
3941
3942 2000-11-07  Akim Demaille  <akim@epita.fr>
3943
3944         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
3945         Merge in a single CPP if/else.
3946
3947 2000-11-07  Akim Demaille  <akim@epita.fr>

3969
3970         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

3986         * src/main.c (main): Don't use `atexit' to register `done', since
3987         it no longer has to remove tmp files, just call `output_files'
3988         when there are no errors.

4091 2000-10-04  Akim Demaille  <akim@epita.fr>
4092
4093         When a literal string is used to define two different tokens,
4094         `bison -v' segfaults.
4095         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
4096
4097         * tests/regression.m4: New file.
4098         Include the core of the sample provided by Piotr Gackiewicz.
4099         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
4100         properly.
4101
4102 2000-10-04  Akim Demaille  <akim@epita.fr>
4103
4104         * src/reader.c (parse_expect_decl): Keep `count' within the size
4105         of `buffer'.
4106         From Neil Booth.
4107
4108 2000-10-02  Paul Eggert  <eggert@twinsun.com>
4109
4110         * bison.s1 (yyparse): Assign the default value
4111         unconditionally, to avoid a GCC warning and make the parser a
4112         tad smaller.
4113
4114 2000-10-02  Akim Demaille  <akim@epita.fr>
4115
4116         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
4117         options.
4118
4119 2000-10-02  Akim Demaille  <akim@epita.fr>
4120
4121         * src/derives.c, src/print.c, src/reduce.c: To ease the
4122         translation, move some `\n' out of the translated strings.
4123
4124 2000-10-02  Akim Demaille  <akim@epita.fr>
4125
4126         The location tracking mechanism is precious for parse error
4127         messages.  Nevertheless, it is enabled only when `@n' is used in
4128         the grammar, which is a different issue (you can use it in error
4129         message, but not in the grammar per se).  Therefore, there should
4130         be another means to enable it.
4131
4132         * src/getargs.c (getargs): Support `--locations'.
4133         (usage): Report it.
4134         * src/getargs.h (locationsflag): Export it.
4135         * src/lex.c (percent_table): Support `%locations'.
4136         * src/reader.c (yylsp_needed): Remove this variable, now replaced
4137         with `locationsflag'.
4138         * doc/bison.texinfo: Document `--locations' and `%locations'.
4139         Sort the options.
4140         * tests/calc.m4: Test it.
4141
4142         For regularity of the names, replace each
4143         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4144         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4145         In addition replace each `flag' with `_flag'.
4146
4147 2000-10-02  Akim Demaille  <akim@epita.fr>
4148
4149         Also test parse error messages, including with YYERROR_VERBOSE.
4150
4151         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4152         associative).
4153         Use it to check the computations.
4154         Use it to check `nonassoc' is honored.
4155         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4156         `--yyerror-verbose'.
4157         (_AT_CHECK_CALC): Adjust to this option.
4158         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4159
4160 2000-10-02  Akim Demaille  <akim@epita.fr>
4161
4162         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
4163         the latter demonstrates a flaw in the handling of non debugging
4164         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4165         was used in order to simplify:
4166
4167         #if YYDEBUG
4168         if (yydebug)
4169         {
4170         ...
4171         }
4172         #endif
4173
4174         into
4175
4176         if (yydebug)
4177         {
4178         ...
4179         }
4180
4181         unfortunately this leads to a CPP conflict when
4182         `--name-prefix=foo' is used since it produces `#define yydebug
4183         foodebug'.
4184
4185         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4186         (YYDPRINTF): New macro.
4187         Spread its use.
4188         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4189         the bison options.
4190         Also test `--verbose', `--defines' and `--name-prefix'.
4191
4192 2000-10-02  Akim Demaille  <akim@epita.fr>
4193
4194         Improve the readability of the produced parsers.
4195
4196         * src/bison.s1: Formatting changes.
4197         Improve the comment related to the `$' mark.
4198         (yydefault): Don't fall through to `yyresume': `goto' there.
4199         * src/output.c (output_parser): When the `$' is met, skip the end
4200         of its line.
4201         New variable, `number_of_dollar_signs', to check there's exactly
4202         one `$' in the parser skeleton.
4203
4204 2000-10-02  Akim Demaille  <akim@epita.fr>
4205
4206         * lib/xstrdup.c: New file, from the fileutils.
4207         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4208         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4209         instead of strlen + xmalloc + strcpy.
4210         * src/symtab.c (copys): Remove, use xstrdup instead.
4211
4212 2000-10-02  Akim Demaille  <akim@epita.fr>
4213
4214         * src/gram.h (associativity): New enum type which replaces the
4215         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4216         `right_assoc', `left_assoc' and `non_assoc'.
4217         Adjust all dependencies.
4218         * src/reader.c: Formatting changes.
4219         (LTYPESTR): Don't define it, use it as a literal in
4220         `reader_output_yylsp'.
4221         * src/symtab.h (symbol_class): New enum type which replaces the
4222         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4223         `sunknown', `stoken and `snterm'.
4224
4225 2000-10-02  Akim Demaille  <akim@epita.fr>
4226
4227         * src/getargs.c (fixed_outfiles): Rename as...
4228         (yaccflag): for consistency and accuracy.
4229         Adjust dependencies.
4230
4231 2000-10-02  Akim Demaille  <akim@epita.fr>
4232
4233         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4234         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4235         difficult and introduced a lot of core dump.  It turns out that
4236         Bison used an implementation of `xmalloc' based on `calloc', and
4237         at various places it does depend upon the initialization to 0.  I
4238         have not tried to isolate the pertinent places, and all the former
4239         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4240         someone should address this issue.
4241
4242         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4243         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

4251         Various anti-`extern in *.c' changes.

4254
4255 2000-10-02  Akim Demaille  <akim@epita.fr>
4256
4257         * src/state.h (nstates, final_state, first_state, first_shift)
4258         (first_reduction): Move their exportation from here...
4259         * src/LR0.h: to here.
4260         Adjust dependencies.
4261         * src/getargs.c (statisticsflag): New variable.

4315         * src/reader.h: New file.
4316         Propagate its use instead of tedious list of `extern' and
4317         prototypes.
4318         * src/reader.c: Formatting changes, topological sort,
4319         s/register//.
4320
4321 2000-10-02  Akim Demaille  <akim@epita.fr>
4322
4323         * src/lex.h: Prototype `lex.c' exported functions.
4324         * src/reader.c: Adjust.
4325         * src/lex.c: Formatting changes.
4326         (safegetc): Rename as...
4327         (xgetc): this.
4328
4329 2000-10-02  Akim Demaille  <akim@epita.fr>
4330
4331         * src/lalr.h: New file.

4334
4335 2000-10-02  Akim Demaille  <akim@epita.fr>
4336
4337         * src/output.c (token_actions): Introduce a temporary array,
4338         YYDEFACT, that makes it possible for this function to use
4339         output_short_table.
4340
4341 2000-10-02  Akim Demaille  <akim@epita.fr>
4342
4343         `user_toknums' is output as a `short[]' in `output.c', while it is
4344         defined as a `int[]' in `reader.c'.  For consistency with the
4345         other output tables, `user_toknums' is now defined as a table of
4346         shorts.
4347
4348         * src/reader.c (user_toknums): Be a short table instead of an int
4349         table.
4350         Adjust dependencies.
4351
4352         Factor the short table outputs.
4353
4354         * src/output.c (output_short_table): New function.
4355         * src/output.c (output_gram, output_stos, output_rule_data)

4357
4358 2000-10-02  Akim Demaille  <akim@epita.fr>
4359
4360         * src/output.c (output): Topological sort of the functions, in
4361         order to get rid of the `static' prototypes.
4362         No longer use `register'.
4363         * src/output.h: New file.
4364         Propagate its inclusion in files explicitly prototyping functions
4365         from output.c.
4366
4367 2000-09-21  Akim Demaille  <akim@epita.fr>

4374         * src/closure.c: Formatting changes, topological sort over the
4375         functions, use of closure.h.
4376         (initialize_closure, finalize_closure):  Rename as...
4377         (new_closure, free_closure): these.  Adjust dependencies.
4378         * src/LR0.c: Formatting changes, topological sort, use of
4379         cloture.h.

4384 2000-09-20  Akim Demaille  <akim@epita.fr>
4385
4386         * src/acconfig.h: Don't protect config.h against multiple
4387         inclusion.
4388         Don't define PARAMS.
4389         * src/system.h: Define PARAMS.
4390         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
4391         purpose of config.h.  system.h must not try to fix wrong
4392         definitions in config.h.
4393
4394 2000-09-20  Akim Demaille  <akim@epita.fr>

4406         Use these macros to test bison with options `', `--raw',
4407         `--debug', `--yacc', `--yacc --debug'.
4408
4409 2000-09-19  Akim Demaille  <akim@epita.fr>
4410
4411         * src/output.c: Formatting changes.
4412         * src/machine.h: Remove, leaving its contents in...

4432

4470         (VERSION_STRING): Remove.
4471
4472 2000-04-14  Akim Demaille  <akim@epita.fr>
4473
4474         * src/reader.c (copy_comment2): New function, same as former

4529         * configure.in: Adjust.
4530         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

4552
4553         * src/Makefile.am (bison.simple): Fix the awk program: quote only
4554         the file name, not the whole `#line LINE FILE'.
4555
4556 2000-03-17  Akim Demaille  <akim@epita.fr>
4557
4558         On syntax errors, report the token on which we choked.
4559
4560         * src/bison.s1 (yyparse): In the label yyerrlab, when

4578
4579         * src/reader.c (copy_definition): Use copy_string and
4580         copy_comment.  Removed now unused `match', `ended',
4581         `cplus_comment'.
4582         (copy_comment, copy_string): Moved, to be visible from
4583         copy_definition.
4584
4585 2000-03-17  Akim Demaille  <akim@epita.fr>
4586
4587         * src/reader.c (copy_string): Declare `static inline'.  No
4588         problems with inline, since it is checked by configure.

4609
4610         Change the handling of @s so that they behave exactly like $s.
4611         There is now a pseudo variable @$ (readble and writable), location
4612         of the lhs of the rule (by default ranging from the location of
4613         the first symbol of the rhs, to the location of the last symbol,
4614         or, if the rhs is empty, YYLLOC).
4615
4616         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4617         yyval.
4618         (yyparse): When providing a default semantic action, provide a
4619         default location action.
4620         (after the $): No longer change `*YYLSP', just stack YYLOC the
4621         same way you stack YYVAL.
4622         * src/reader.c (read_declarations): Use warns.
4623         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4624         (copy_action, case '@'): Likewise.
4625         Use a standard error message, to save useless work from
4626         translators.
4627
4628 2000-03-17  Akim Demaille  <akim@epita.fr>
4629
4630         * src/bison.s1: Formatting and cosmetics changes.

4632         Update the Copyright notice.
4633
4634 2000-03-17  Akim Demaille  <akim@epita.fr>
4635
4636         * src/bison.s1 (#line): All set to `#line' only, since the
4637         Makefile now handles them.
4638
4639 2000-03-16  Akim Demaille  <akim@epita.fr>
4640

4645
4646 2000-03-16  Akim Demaille  <akim@epita.fr>
4647
4648         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4649         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4650         One `#if YYDEBUG' remains, since it uses variables which are
4651         defined only if `YYDEBUG != 0'.
4652
4653 2000-03-16  Akim Demaille  <akim@epita.fr>
4654
4655         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
4656         and related variables so that the similarities are highlighted.

4666 2000-03-16  Akim Demaille  <akim@epita.fr>
4667
4668         Do not hard code values of directories in `configure.in'.
4669         Update the `configure' tool chain.
4670
4671         * configure.in (XPFILE, XPFILE1, LOCALEDIR): Remove, handled by
4672         src/makefile.am.
4673         (VERSION_STRING): Use the third arg of AC_DEFINE_UNQUOTED.
4674         (AC_OUTPUT): Add m4/Makefile.
4675         Bump to bison 1.28a, 1.29 has never been released.
