 385         * config/: New.
 386         * configure.in: Require Autoconf 2.50.
 387         Update to gettext 0.10.38.
 388
 389 2001-03-16  Akim Demaille  <akim@epita.fr>
 390
 391         * doc/bison.texinfo: ANSIfy the examples.
 392
 393 2001-03-16  Akim Demaille  <akim@epita.fr>
 394
 395         * getargs.c (skeleton): New variable.
 396         (longopts): --skeleton is a new option.
 397         (shortopts, getargs): -S is a new option.
 398         * getargs.h: Declare skeleton.
 399         * output.c (output_parser): Use it.
 400
 401 2001-03-16  Akim Demaille  <akim@epita.fr>
 402
 403         * m4/strerror_r.m4: New.
 404         * m4/error.m4: Run AC_FUNC_STRERROR_R.
 405         * lib/error.h, lib/error.c: Update.
 406
 407 2001-03-16  Akim Demaille  <akim@epita.fr>
 408
 409         * src/getargs.c (longopts): Clean up.
 410
 411 2001-02-21  Akim Demaille  <akim@epita.fr>
 412
 413         * src/reader.c (gensym): `gensym_count' is your own.
 414         Use a static buf to create the symbol name, as token_buffer is no
 415         longer a buffer.
 416
 417 2001-02-08  Akim Demaille  <akim@epita.fr>
 418
 419         * src/conflicts.c (conflict_report): Be sure not to append to res
 420         between two calls, which could happen if both first sprintf were
 421         skipped, but not the first cp += strlen.
 422
 423 2001-02-08  Akim Demaille  <akim@epita.fr>
 424
 425         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
 426         New, from fileutils 4.0.37.
 427         * configure.in: Require Autoconf 2.49c.  I took some time before
 428         making this decision.  This is the only way out for portability
 429         issues in Bison, it would mean way too much duplicate effort to
 430         import in Bison features implemented in 2.49c since 2.13.
 431         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
 432
 433 2001-02-02  Akim Demaille  <akim@epita.fr>
 434
 435         * lib/malloc.c, lib/realloc.c: New, from the fileutils 4.0.37.

 437
 438 2001-01-19  Akim Demaille  <akim@epita.fr>
 439
 440         Get rid of the ad hoc handling of token_buffer in the scanner: use
 441         the obstacks.
 442
 443         * src/lex.c (token_obstack): New.
 444         (init_lex): Initialize it.  No longer call...
 445         (grow_token_buffer): this.  Remove it.
 446         Adjust all the places which used it to use the obstack.
 447
 448 2001-01-19  Akim Demaille  <akim@epita.fr>
 449
 450         * src/lex.h: Rename all the tokens:
 451         s/\bENDFILE\b/tok_eof/g;
 452         s/\bIDENTIFIER\b/tok_identifier/g;
 453         etc.
 454         Let them be enums, not #define, to ease debugging.
 455         Adjust all the code.
 456
 457 2001-01-18  Akim Demaille  <akim@epita.fr>
 458
 459         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 460         * src/lex.c (maxtoken, grow_token_buffer): Static.
 461
 462 2001-01-18  Akim Demaille  <akim@epita.fr>
 463
 464         Since we now use obstacks, more % directives can be enabled.
 465
 466         * src/lex.c (percent_table): Also accept `%yacc',
 467         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 468         `%debug'.
 469         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 470         instead of returning a token.
 471         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 472         * src/reader.c (read_declarations): Adjust.
 473         * src/files.c (open_files): Don't call `compute_base_names', don't
 474         compute `attrsfile' since they depend upon data which might be
 475         *in* the input file now.
 476         (output_files): Do it here.
 477         * src/output.c (output_headers): Document the fact that this patch
 478         introduces a guaranteed SEGV for semantic parsers.
 479         * doc/bison.texinfo: Document them.
 480         * tests/suite.at: Exercise these %options.
 481
 482 2000-12-20  Akim Demaille  <akim@epita.fr>
 483
 484         Also handle the output file (--verbose) with obstacks.

 486         * files.c (foutput): Remove.

 488         Adjust all dependencies.
 489         * src/conflicts.c: Return a string.
 490         * src/system.h (obstack_grow_string): Rename as...
 491         (obstack_sgrow): this.  Be ready to work with non literals.
 492         (obstack_fgrow4): New.
 493
 494 2000-12-20  Akim Demaille  <akim@epita.fr>
 495
 496         * src/files.c (open_files): Fix the computation of short_base_name
 497         in the case of `-o foo.tab.c'.
 498
 499 2000-12-20  Akim Demaille  <akim@epita.fr>
 500
 501         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 502         (copy_dollar): Now that everything uses obstacks, get rid of the
 503         FILE * parameters.
 504
 505 2000-12-20  Akim Demaille  <akim@epita.fr>
 506
 507         * src/files.c (open_files): Actually the `.output' file is based
 508         on the short_base_name, not base_name.
 509         * tests/suite.at (Checking output file names): Adjust.
 510
 511 2000-12-20  Akim Demaille  <akim@epita.fr>

 514         * src/bison.simple: this.
 515         * src/Makefile.am: Use pkgdata instead of data.
 516
 517 2000-12-20  Akim Demaille  <akim@epita.fr>
 518
 519         * src/files.c (guard_obstack): New.

 528         vars.
 529         (open_files): Don't compute them.

 535
 536         * src/files.c (strsuffix): New.
 537         (stringappend): Be just like strcat but allocate.
 538         (base_names): Eve out from open_files.
 539         Try to simplify the rather hairy computation of base_name and
 540         short_base_name.
 541         (open_files): Use it.
 542         * tests/suite.at (Checking output file names): New test.
 543
 544 2000-12-19  Akim Demaille  <akim@epita.fr>

 548         * src/output.c (output_parser): Recognize `%% actions' instead of
 549         `$'.
 550         * src/bison.s1: s/$/%% actions/.
 551         * src/bison.hairy: Likewise.
 552
 553 2000-12-19  Akim Demaille  <akim@epita.fr>
 554
 555         * src/output.c (output_parser): Compute the `#line' lines when
 556         there are.
 557         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
 558         Suggested by Hans Aberg.
 559
 560 2000-12-19  Akim Demaille  <akim@epita.fr>
 561
 562         Let the handling of the skeleton files be local to the procedures
 563         that use it.
 564
 565         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
 566         longer static.
 567         (fparser, open_extra_files): Remove.
 568         (open_files, output_files): Don't take care of fparser.

 576
 577         * src/file.h (BISON_SIMPLE, BISON_HAIRY): Move from here...

 580 2000-12-19  Akim Demaille  <akim@epita.fr>
 581
 582         * src/files.c (open_files): Yipee!  We no longer need all the code
 583         looking for `/tmp' since we have no tmp file.
 584
 585 2000-12-19  Akim Demaille  <akim@epita.fr>
 586
 587         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 588         New macros.
 589         * src/files.c (open_files): Less dependency on MSDOS etc.

 602         (copy_guard): Quote the file names.
 603         Reported by Laurent Mascherpa.
 604
 605 2000-12-12  Akim Demaille  <akim@epita.fr>

 613
 614         * lib/obstack.h: Formatting changes.
 615         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 616         prevents type checking.
 617         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 618         cast the value to (void *): assigning a `foo *' to a `void *'
 619         variable is valid.
 620         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 621         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
 622         append characters.
 623
 624 2000-11-17  Akim Demaille  <akim@epita.fr>
 625
 626         * tests/Makefile.am (suite.m4, regression.m4, calc.m4): Rename

 637
 638         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
 639         macros.

 656
 657 2000-11-07  Akim Demaille  <akim@epita.fr>
 658
 659         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
 660         Merge in a single CPP if/else.
 661
 662 2000-11-07  Akim Demaille  <akim@epita.fr>
 663
 664         * src/output.c (output): Remove useless variables.
 665         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second

 667         Qualify it `const'.
 668         (obstack_copy, obstack_copy0): Rename the second argument as
 669         `address' for consistency.  Qualify it `const'.
 670         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 671         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
 672         `const' their input argument (`data' or `address').
 673         Adjust the corresponding macros to include `const' in casts.
 674
 675 2000-11-03  Akim Demaille  <akim@epita.fr>
 676
 677         * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

 680
 681 2000-11-03  Akim Demaille  <akim@epita.fr>
 682
 683         For some reason, this was not applied.
 684
 685         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 698         (done): Rename as...
 699         (output_files): this.
 700         Use `obstack_save'.
 701         * src/main.c (main): Don't use `atexit' to register `done', since
 702         it no longer has to remove tmp files, just call `output_files'
 703         when there are no errors.
 704
 705 2000-11-02  Akim Demaille  <akim@epita.fr>

 719         Convert to using obstacks.

 773
 774         * src/reader.c (copy_comment2): Expect the input stream to be on
 775         the `/' which is suspected to open a comment, instead of being
 776         called after `//' or `/*' was read.
 777         (copy_comment, copy_definition, parse_union_decl, copy_action)
 778         (copy_guard): Adjust.

 807
 808         When a literal string is used to define two different tokens,
 809         `bison -v' segfaults.
 810         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 811
 812         * tests/regression.m4: New file.

 823 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 824
 825         * bison.s1 (yyparse): Assign the default value
 826         unconditionally, to avoid a GCC warning and make the parser a
 827         tad smaller.
 828
 829 2000-10-02  Akim Demaille  <akim@epita.fr>
 830
 831         * src/getargs.c (getargs): Don't dump `--help' on unrecognized

 835
 836         * src/derives.c, src/print.c, src/reduce.c: To ease the

 838
 839 2000-10-02  Akim Demaille  <akim@epita.fr>
 840
 841         The location tracking mechanism is precious for parse error
 842         messages.  Nevertheless, it is enabled only when `@n' is used in
 843         the grammar, which is a different issue (you can use it in error
 844         message, but not in the grammar per se).  Therefore, there should
 845         be another means to enable it.
 846
 847         * src/getargs.c (getargs): Support `--locations'.
 848         (usage): Report it.
 849         * src/getargs.h (locationsflag): Export it.
 850         * src/lex.c (percent_table): Support `%locations'.
 851         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 852         with `locationsflag'.
 853         * doc/bison.texinfo: Document `--locations' and `%locations'.
 854         Sort the options.
 855         * tests/calc.m4: Test it.
 856
 857         For regularity of the names, replace each
 858         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 859         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 860         In addition replace each `flag' with `_flag'.
 861
 862 2000-10-02  Akim Demaille  <akim@epita.fr>
 863
 864         Also test parse error messages, including with YYERROR_VERBOSE.
 865
 866         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 867         associative).
 868         Use it to check the computations.
 869         Use it to check `nonassoc' is honored.
 870         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 871         `--yyerror-verbose'.
 872         (_AT_CHECK_CALC): Adjust to this option.
 873         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 874
 875 2000-10-02  Akim Demaille  <akim@epita.fr>
 876
 877         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 878         the latter demonstrates a flaw in the handling of non debugging
 879         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 880         was used in order to simplify:
 881
 882         #if YYDEBUG
 883         if (yydebug)
 884         {
 885         ...
 886         }
 887         #endif
 888
 889         into
 890
 891         if (yydebug)
 892         {
 893         ...
 894         }
 895
 896         unfortunately this leads to a CPP conflict when
 897         `--name-prefix=foo' is used since it produces `#define yydebug
 898         foodebug'.
 899
 900         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 901         (YYDPRINTF): New macro.
 902         Spread its use.
 903         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 904         the bison options.
 905         Also test `--verbose', `--defines' and `--name-prefix'.
 906
 907 2000-10-02  Akim Demaille  <akim@epita.fr>
 908
 909         Improve the readability of the produced parsers.
 910
 911         * src/bison.s1: Formatting changes.
 912         Improve the comment related to the `$' mark.
 913         (yydefault): Don't fall through to `yyresume': `goto' there.
 914         * src/output.c (output_parser): When the `$' is met, skip the end
 915         of its line.
 916         New variable, `number_of_dollar_signs', to check there's exactly
 917         one `$' in the parser skeleton.
 918
 919 2000-10-02  Akim Demaille  <akim@epita.fr>
 920
 921         * lib/xstrdup.c: New file, from the fileutils.
 922         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 923         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 924         instead of strlen + xmalloc + strcpy.
 925         * src/symtab.c (copys): Remove, use xstrdup instead.
 926
 927 2000-10-02  Akim Demaille  <akim@epita.fr>
 928
 929         * src/gram.h (associativity): New enum type which replaces the
 930         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 931         `right_assoc', `left_assoc' and `non_assoc'.
 932         Adjust all dependencies.
 933         * src/reader.c: Formatting changes.
 934         (LTYPESTR): Don't define it, use it as a literal in
 935         `reader_output_yylsp'.
 936         * src/symtab.h (symbol_class): New enum type which replaces the
 937         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 938         `sunknown', `stoken and `snterm'.
 939
 940 2000-10-02  Akim Demaille  <akim@epita.fr>
 941
 942         * src/getargs.c (fixed_outfiles): Rename as...
 943         (yaccflag): for consistency and accuracy.
 944         Adjust dependencies.
 945
 946 2000-10-02  Akim Demaille  <akim@epita.fr>
 947
 948         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 949         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 950         difficult and introduced a lot of core dump.  It turns out that
 951         Bison used an implementation of `xmalloc' based on `calloc', and
 952         at various places it does depend upon the initialization to 0.  I
 953         have not tried to isolate the pertinent places, and all the former
 954         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 955         someone should address this issue.
 956
 957         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 958         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 959         files.
 960         Adjust dependencies.

 970 2000-10-02  Akim Demaille  <akim@epita.fr>
 971
 972         * src/state.h (nstates, final_state, first_state, first_shift)
 973         (first_reduction): Move their exportation from here...
 974         * src/LR0.h: to here.
 975         Adjust dependencies.

1050 2000-10-02  Akim Demaille  <akim@epita.fr>
1051
1052         * src/output.c (token_actions): Introduce a temporary array,
1053         YYDEFACT, that makes it possible for this function to use
1054         output_short_table.
1055
1056 2000-10-02  Akim Demaille  <akim@epita.fr>
1057
1058         `user_toknums' is output as a `short[]' in `output.c', while it is
1059         defined as a `int[]' in `reader.c'.  For consistency with the
1060         other output tables, `user_toknums' is now defined as a table of
1061         shorts.
1062
1063         * src/reader.c (user_toknums): Be a short table instead of an int
1064         table.

1076         order to get rid of the `static' prototypes.
1077         No longer use `register'.
1078         * src/output.h: New file.
1079         Propagate its inclusion in files explicitly prototyping functions

1102         inclusion.
1103         Don't define PARAMS.
1104         * src/system.h: Define PARAMS.
1105         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
1106         purpose of config.h.  system.h must not try to fix wrong
1107         definitions in config.h.

1244         * configure.in: Adjust.
1245         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

1269         the file name, not the whole `#line LINE FILE'.
1270
1271 2000-03-17  Akim Demaille  <akim@epita.fr>
1272
1273         On syntax errors, report the token on which we choked.
1274
1275         * src/bison.s1 (yyparse): In the label yyerrlab, when

1293

1295         copy_comment.  Removed now unused `match', `ended',
1296         `cplus_comment'.
1297         (copy_comment, copy_string): Moved, to be visible from
1298         copy_definition.
1299

1301
1302         * src/reader.c (copy_string): Declare `static inline'.  No

1324
1325         Change the handling of @s so that they behave exactly like $s.
1326         There is now a pseudo variable @$ (readble and writable), location
1327         of the lhs of the rule (by default ranging from the location of
1328         the first symbol of the rhs, to the location of the last symbol,
1329         or, if the rhs is empty, YYLLOC).
1330
1331         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1332         yyval.
1333         (yyparse): When providing a default semantic action, provide a
1334         default location action.
1335         (after the $): No longer change `*YYLSP', just stack YYLOC the
1336         same way you stack YYVAL.
1337         * src/reader.c (read_declarations): Use warns.
1338         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1339         (copy_action, case '@'): Likewise.
1340         Use a standard error message, to save useless work from
1341         translators.
1342
1343 2000-03-17  Akim Demaille  <akim@epita.fr>
1344

1362
1363         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1364         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1365         One `#if YYDEBUG' remains, since it uses variables which are
1366         defined only if `YYDEBUG != 0'.
1367
1368 2000-03-16  Akim Demaille  <akim@epita.fr>

1394         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

1400         the proper line number and file name.
1401         (DEFS): Propagate the location of bison library files and of the
1402         locale files.
1403         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1404         builddir.
1405         * acinclude.m4: Remove, replaced by the directory m4.
1406         * m4/Makefile.am (EXTRA_DIST): New variable.
1407         * m4/gettext.m4: New file, from the fileutils.
