 383         (shortopts, getargs): -S is a new option.
 384         * getargs.h: Declare skeleton.
 385         * output.c (output_parser): Use it.
 386
 387 2001-03-16  Akim Demaille  <akim@epita.fr>
 388
 389         * m4/strerror_r.m4: New.

 392
 393 2001-03-16  Akim Demaille  <akim@epita.fr>
 394
 395         * src/getargs.c (longopts): Clean up.
 396
 397 2001-02-21  Akim Demaille  <akim@epita.fr>
 398
 399         * src/reader.c (gensym): `gensym_count' is your own.
 400         Use a static buf to create the symbol name, as token_buffer is no
 401         longer a buffer.
 402
 403 2001-02-08  Akim Demaille  <akim@epita.fr>
 404
 405         * src/conflicts.c (conflict_report): Be sure not to append to res
 406         between two calls, which could happen if both first sprintf were
 407         skipped, but not the first cp += strlen.
 408
 409 2001-02-08  Akim Demaille  <akim@epita.fr>
 410
 411         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
 412         New, from fileutils 4.0.37.
 413         * configure.in: Require Autoconf 2.49c.  I took some time before
 414         making this decision.  This is the only way out for portability
 415         issues in Bison, it would mean way too much duplicate effort to
 416         import in Bison features implemented in 2.49c since 2.13.
 417         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
 418
 419 2001-02-02  Akim Demaille  <akim@epita.fr>
 420

 423
 424 2001-01-19  Akim Demaille  <akim@epita.fr>
 425
 426         Get rid of the ad hoc handling of token_buffer in the scanner: use
 427         the obstacks.
 428
 429         * src/lex.c (token_obstack): New.
 430         (init_lex): Initialize it.  No longer call...
 431         (grow_token_buffer): this.  Remove it.
 432         Adjust all the places which used it to use the obstack.
 433
 434 2001-01-19  Akim Demaille  <akim@epita.fr>
 435
 436         * src/lex.h: Rename all the tokens:
 437         s/\bENDFILE\b/tok_eof/g;
 438         s/\bIDENTIFIER\b/tok_identifier/g;
 439         etc.
 440         Let them be enums, not #define, to ease debugging.
 441         Adjust all the code.
 442
 443 2001-01-18  Akim Demaille  <akim@epita.fr>
 444
 445         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 446         * src/lex.c (maxtoken, grow_token_buffer): Static.
 447
 448 2001-01-18  Akim Demaille  <akim@epita.fr>
 449
 450         Since we now use obstacks, more % directives can be enabled.
 451
 452         * src/lex.c (percent_table): Also accept `%yacc',
 453         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 454         `%debug'.
 455         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 456         instead of returning a token.
 457         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 458         * src/reader.c (read_declarations): Adjust.
 459         * src/files.c (open_files): Don't call `compute_base_names', don't
 460         compute `attrsfile' since they depend upon data which might be
 461         *in* the input file now.
 462         (output_files): Do it here.
 463         * src/output.c (output_headers): Document the fact that this patch
 464         introduces a guaranteed SEGV for semantic parsers.
 465         * doc/bison.texinfo: Document them.
 466         * tests/suite.at: Exercise these %options.
 467
 468 2000-12-20  Akim Demaille  <akim@epita.fr>
 469
 470         Also handle the output file (--verbose) with obstacks.

 474         Adjust all dependencies.

 476         * src/system.h (obstack_grow_string): Rename as...
 477         (obstack_sgrow): this.  Be ready to work with non literals.
 478         (obstack_fgrow4): New.
 479
 480 2000-12-20  Akim Demaille  <akim@epita.fr>
 481
 482         * src/files.c (open_files): Fix the computation of short_base_name
 483         in the case of `-o foo.tab.c'.
 484
 485 2000-12-20  Akim Demaille  <akim@epita.fr>
 486
 487         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 488         (copy_dollar): Now that everything uses obstacks, get rid of the
 489         FILE * parameters.
 490
 491 2000-12-20  Akim Demaille  <akim@epita.fr>
 492
 493         * src/files.c (open_files): Actually the `.output' file is based
 494         on the short_base_name, not base_name.
 495         * tests/suite.at (Checking output file names): Adjust.
 496
 497 2000-12-20  Akim Demaille  <akim@epita.fr>

 500         * src/bison.simple: this.
 501         * src/Makefile.am: Use pkgdata instead of data.
 502
 503 2000-12-20  Akim Demaille  <akim@epita.fr>
 504
 505         * src/files.c (guard_obstack): New.

 512
 513         * src/files.c (outfile, defsfile, actfile): Removed as global
 514         vars.
 515         (open_files): Don't compute them.

 522         * src/files.c (strsuffix): New.
 523         (stringappend): Be just like strcat but allocate.
 524         (base_names): Eve out from open_files.
 525         Try to simplify the rather hairy computation of base_name and
 526         short_base_name.
 527         (open_files): Use it.
 528         * tests/suite.at (Checking output file names): New test.
 529
 530 2000-12-19  Akim Demaille  <akim@epita.fr>

 534         * src/output.c (output_parser): Recognize `%% actions' instead of
 535         `$'.
 536         * src/bison.s1: s/$/%% actions/.
 537         * src/bison.hairy: Likewise.
 538
 539 2000-12-19  Akim Demaille  <akim@epita.fr>
 540
 541         * src/output.c (output_parser): Compute the `#line' lines when
 542         there are.
 543         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
 544         Suggested by Hans Aberg.
 545
 546 2000-12-19  Akim Demaille  <akim@epita.fr>
 547
 548         Let the handling of the skeleton files be local to the procedures
 549         that use it.
 550
 551         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
 552         longer static.
 553         (fparser, open_extra_files): Remove.
 554         (open_files, output_files): Don't take care of fparser.

 561 2000-12-19  Akim Demaille  <akim@epita.fr>
 562
 563         * src/file.h (BISON_SIMPLE, BISON_HAIRY): Move from here...

 566 2000-12-19  Akim Demaille  <akim@epita.fr>
 567
 568         * src/files.c (open_files): Yipee!  We no longer need all the code
 569         looking for `/tmp' since we have no tmp file.
 570
 571 2000-12-19  Akim Demaille  <akim@epita.fr>
 572
 573         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 574         New macros.
 575         * src/files.c (open_files): Less dependency on MSDOS etc.

 588         (copy_guard): Quote the file names.
 589         Reported by Laurent Mascherpa.
 590
 591 2000-12-12  Akim Demaille  <akim@epita.fr>

 599
 600         * lib/obstack.h: Formatting changes.
 601         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 602         prevents type checking.
 603         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 604         cast the value to (void *): assigning a `foo *' to a `void *'
 605         variable is valid.
 606         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 607         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
 608         append characters.
 609

 623
 624         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
 625         macros.

 642
 643 2000-11-07  Akim Demaille  <akim@epita.fr>
 644
 645         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
 646         Merge in a single CPP if/else.
 647
 648 2000-11-07  Akim Demaille  <akim@epita.fr>

 655         `address' for consistency.  Qualify it `const'.
 656         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 657         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
 658         `const' their input argument (`data' or `address').
 659         Adjust the corresponding macros to include `const' in casts.

 662
 663         * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

 668
 669         For some reason, this was not applied.
 670
 671         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 686         Use `obstack_save'.
 687         * src/main.c (main): Don't use `atexit' to register `done', since
 688         it no longer has to remove tmp files, just call `output_files'
 689         when there are no errors.
 690
 691 2000-11-02  Akim Demaille  <akim@epita.fr>

 758 2000-10-16  Akim Demaille  <akim@epita.fr>
 759
 760         * src/reader.c (copy_comment2): Expect the input stream to be on
 761         the `/' which is suspected to open a comment, instead of being
 762         called after `//' or `/*' was read.
 763         (copy_comment, copy_definition, parse_union_decl, copy_action)
 764         (copy_guard): Adjust.

 794         When a literal string is used to define two different tokens,
 795         `bison -v' segfaults.
 796         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 797
 798         * tests/regression.m4: New file.

 809 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 810
 811         * bison.s1 (yyparse): Assign the default value
 812         unconditionally, to avoid a GCC warning and make the parser a
 813         tad smaller.
 814
 815 2000-10-02  Akim Demaille  <akim@epita.fr>
 816
 817         * src/getargs.c (getargs): Don't dump `--help' on unrecognized

 821
 822         * src/derives.c, src/print.c, src/reduce.c: To ease the

 824
 825 2000-10-02  Akim Demaille  <akim@epita.fr>
 826
 827         The location tracking mechanism is precious for parse error
 828         messages.  Nevertheless, it is enabled only when `@n' is used in
 829         the grammar, which is a different issue (you can use it in error
 830         message, but not in the grammar per se).  Therefore, there should
 831         be another means to enable it.
 832
 833         * src/getargs.c (getargs): Support `--locations'.
 834         (usage): Report it.
 835         * src/getargs.h (locationsflag): Export it.
 836         * src/lex.c (percent_table): Support `%locations'.
 837         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 838         with `locationsflag'.
 839         * doc/bison.texinfo: Document `--locations' and `%locations'.
 840         Sort the options.
 841         * tests/calc.m4: Test it.
 842
 843         For regularity of the names, replace each
 844         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 845         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 846         In addition replace each `flag' with `_flag'.
 847
 848 2000-10-02  Akim Demaille  <akim@epita.fr>
 849
 850         Also test parse error messages, including with YYERROR_VERBOSE.
 851
 852         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 853         associative).
 854         Use it to check the computations.
 855         Use it to check `nonassoc' is honored.
 856         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 857         `--yyerror-verbose'.
 858         (_AT_CHECK_CALC): Adjust to this option.
 859         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 860
 861 2000-10-02  Akim Demaille  <akim@epita.fr>
 862
 863         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 864         the latter demonstrates a flaw in the handling of non debugging
 865         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 866         was used in order to simplify:
 867
 868         #if YYDEBUG
 869         if (yydebug)
 870         {
 871         ...
 872         }
 873         #endif
 874
 875         into
 876
 877         if (yydebug)
 878         {
 879         ...
 880         }
 881
 882         unfortunately this leads to a CPP conflict when
 883         `--name-prefix=foo' is used since it produces `#define yydebug
 884         foodebug'.
 885
 886         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 887         (YYDPRINTF): New macro.
 888         Spread its use.
 889         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 890         the bison options.
 891         Also test `--verbose', `--defines' and `--name-prefix'.
 892
 893 2000-10-02  Akim Demaille  <akim@epita.fr>
 894
 895         Improve the readability of the produced parsers.
 896
 897         * src/bison.s1: Formatting changes.
 898         Improve the comment related to the `$' mark.
 899         (yydefault): Don't fall through to `yyresume': `goto' there.
 900         * src/output.c (output_parser): When the `$' is met, skip the end
 901         of its line.
 902         New variable, `number_of_dollar_signs', to check there's exactly
 903         one `$' in the parser skeleton.
 904
 905 2000-10-02  Akim Demaille  <akim@epita.fr>
 906
 907         * lib/xstrdup.c: New file, from the fileutils.
 908         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 909         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 910         instead of strlen + xmalloc + strcpy.
 911         * src/symtab.c (copys): Remove, use xstrdup instead.
 912
 913 2000-10-02  Akim Demaille  <akim@epita.fr>
 914
 915         * src/gram.h (associativity): New enum type which replaces the
 916         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 917         `right_assoc', `left_assoc' and `non_assoc'.
 918         Adjust all dependencies.
 919         * src/reader.c: Formatting changes.
 920         (LTYPESTR): Don't define it, use it as a literal in
 921         `reader_output_yylsp'.
 922         * src/symtab.h (symbol_class): New enum type which replaces the
 923         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 924         `sunknown', `stoken and `snterm'.
 925
 926 2000-10-02  Akim Demaille  <akim@epita.fr>
 927
 928         * src/getargs.c (fixed_outfiles): Rename as...
 929         (yaccflag): for consistency and accuracy.
 930         Adjust dependencies.
 931
 932 2000-10-02  Akim Demaille  <akim@epita.fr>
 933
 934         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 935         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 936         difficult and introduced a lot of core dump.  It turns out that
 937         Bison used an implementation of `xmalloc' based on `calloc', and
 938         at various places it does depend upon the initialization to 0.  I
 939         have not tried to isolate the pertinent places, and all the former
 940         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 941         someone should address this issue.
 942
 943         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 944         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 945         files.
 946         Adjust dependencies.

 956 2000-10-02  Akim Demaille  <akim@epita.fr>
 957
 958         * src/state.h (nstates, final_state, first_state, first_shift)
 959         (first_reduction): Move their exportation from here...
 960         * src/LR0.h: to here.
 961         Adjust dependencies.

1036 2000-10-02  Akim Demaille  <akim@epita.fr>
1037
1038         * src/output.c (token_actions): Introduce a temporary array,
1039         YYDEFACT, that makes it possible for this function to use
1040         output_short_table.
1041
1042 2000-10-02  Akim Demaille  <akim@epita.fr>
1043
1044         `user_toknums' is output as a `short[]' in `output.c', while it is
1045         defined as a `int[]' in `reader.c'.  For consistency with the
1046         other output tables, `user_toknums' is now defined as a table of
1047         shorts.
1048
1049         * src/reader.c (user_toknums): Be a short table instead of an int
1050         table.

1062         order to get rid of the `static' prototypes.
1063         No longer use `register'.
1064         * src/output.h: New file.
1065         Propagate its inclusion in files explicitly prototyping functions
1066         from output.c.

1088         inclusion.
1089         Don't define PARAMS.
1090         * src/system.h: Define PARAMS.
1091         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
1092         purpose of config.h.  system.h must not try to fix wrong
1093         definitions in config.h.

1118         Let all `extern' declarations about getargs.c be replaced with

1256
1257 2000-03-17  Akim Demaille  <akim@epita.fr>
1258
1259         On syntax errors, report the token on which we choked.

1281         copy_comment.  Removed now unused `match', `ended',
1282         `cplus_comment'.
1283         (copy_comment, copy_string): Moved, to be visible from
1284         copy_definition.
1285

1287

1310
1311         Change the handling of @s so that they behave exactly like $s.
1312         There is now a pseudo variable @$ (readble and writable), location
1313         of the lhs of the rule (by default ranging from the location of
1314         the first symbol of the rhs, to the location of the last symbol,
1315         or, if the rhs is empty, YYLLOC).
1316
1317         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1318         yyval.
1319         (yyparse): When providing a default semantic action, provide a
1320         default location action.
1321         (after the $): No longer change `*YYLSP', just stack YYLOC the
1322         same way you stack YYVAL.
1323         * src/reader.c (read_declarations): Use warns.
1324         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1325         (copy_action, case '@'): Likewise.
1326         Use a standard error message, to save useless work from
1327         translators.
1328
1329 2000-03-17  Akim Demaille  <akim@epita.fr>
1330

1348
1349         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1350         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1351         One `#if YYDEBUG' remains, since it uses variables which are
1352         defined only if `YYDEBUG != 0'.
1353
1354 2000-03-16  Akim Demaille  <akim@epita.fr>

1380         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

1386         the proper line number and file name.
1387         (DEFS): Propagate the location of bison library files and of the
1388         locale files.
1389         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1390         builddir.
1391         * acinclude.m4: Remove, replaced by the directory m4.
1392         * m4/Makefile.am (EXTRA_DIST): New variable.
1393         * m4/gettext.m4: New file, from the fileutils.
