  57
  58         * src/output.c (output_parser): Replace most of the skeleton copy code
  59         with something new. Skeletons are now processed character by character
  60         rather than line by line, and Bison looks for '%%' macros. This is the
  61         first step in making Bison's output process (a lot) more flexible.

 388
 389 2001-02-21  Akim Demaille  <akim@epita.fr>
 390
 391         * src/reader.c (gensym): `gensym_count' is your own.
 392         Use a static buf to create the symbol name, as token_buffer is no
 393         longer a buffer.
 394
 395 2001-02-08  Akim Demaille  <akim@epita.fr>
 396
 397         * src/conflicts.c (conflict_report): Be sure not to append to res
 398         between two calls, which could happen if both first sprintf were
 399         skipped, but not the first cp += strlen.
 400
 401 2001-02-08  Akim Demaille  <akim@epita.fr>
 402
 403         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
 404         New, from fileutils 4.0.37.
 405         * configure.in: Require Autoconf 2.49c.  I took some time before
 406         making this decision.  This is the only way out for portability
 407         issues in Bison, it would mean way too much duplicate effort to
 408         import in Bison features implemented in 2.49c since 2.13.
 409         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
 410
 411 2001-02-02  Akim Demaille  <akim@epita.fr>

 415
 416 2001-01-19  Akim Demaille  <akim@epita.fr>
 417
 418         Get rid of the ad hoc handling of token_buffer in the scanner: use
 419         the obstacks.
 420
 421         * src/lex.c (token_obstack): New.
 422         (init_lex): Initialize it.  No longer call...
 423         (grow_token_buffer): this.  Remove it.
 424         Adjust all the places which used it to use the obstack.
 425
 426 2001-01-19  Akim Demaille  <akim@epita.fr>
 427
 428         * src/lex.h: Rename all the tokens:
 429         s/\bENDFILE\b/tok_eof/g;
 430         s/\bIDENTIFIER\b/tok_identifier/g;
 431         etc.
 432         Let them be enums, not #define, to ease debugging.
 433         Adjust all the code.
 434
 435 2001-01-18  Akim Demaille  <akim@epita.fr>
 436
 437         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 438         * src/lex.c (maxtoken, grow_token_buffer): Static.
 439
 440 2001-01-18  Akim Demaille  <akim@epita.fr>
 441
 442         Since we now use obstacks, more % directives can be enabled.
 443
 444         * src/lex.c (percent_table): Also accept `%yacc',
 445         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 446         `%debug'.
 447         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 448         instead of returning a token.
 449         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 450         * src/reader.c (read_declarations): Adjust.
 451         * src/files.c (open_files): Don't call `compute_base_names', don't
 452         compute `attrsfile' since they depend upon data which might be
 453         *in* the input file now.
 454         (output_files): Do it here.
 455         * src/output.c (output_headers): Document the fact that this patch
 456         introduces a guaranteed SEGV for semantic parsers.
 457         * doc/bison.texinfo: Document them.
 458         * tests/suite.at: Exercise these %options.
 459

 468         * src/system.h (obstack_grow_string): Rename as...
 469         (obstack_sgrow): this.  Be ready to work with non literals.
 470         (obstack_fgrow4): New.
 471
 472 2000-12-20  Akim Demaille  <akim@epita.fr>
 473
 474         * src/files.c (open_files): Fix the computation of short_base_name
 475         in the case of `-o foo.tab.c'.
 476
 477 2000-12-20  Akim Demaille  <akim@epita.fr>
 478
 479         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 480         (copy_dollar): Now that everything uses obstacks, get rid of the
 481         FILE * parameters.
 482
 483 2000-12-20  Akim Demaille  <akim@epita.fr>
 484
 485         * src/files.c (open_files): Actually the `.output' file is based
 486         on the short_base_name, not base_name.
 487         * tests/suite.at (Checking output file names): Adjust.
 488
 489 2000-12-20  Akim Demaille  <akim@epita.fr>

 492         * src/bison.simple: this.
 493         * src/Makefile.am: Use pkgdata instead of data.
 494
 495 2000-12-20  Akim Demaille  <akim@epita.fr>
 496
 497         * src/files.c (guard_obstack): New.

 506         vars.
 507         (open_files): Don't compute them.

 513
 514         * src/files.c (strsuffix): New.
 515         (stringappend): Be just like strcat but allocate.
 516         (base_names): Eve out from open_files.
 517         Try to simplify the rather hairy computation of base_name and
 518         short_base_name.
 519         (open_files): Use it.
 520         * tests/suite.at (Checking output file names): New test.
 521
 522 2000-12-19  Akim Demaille  <akim@epita.fr>

 526         * src/output.c (output_parser): Recognize `%% actions' instead of
 527         `$'.
 528         * src/bison.s1: s/$/%% actions/.
 529         * src/bison.hairy: Likewise.
 530
 531 2000-12-19  Akim Demaille  <akim@epita.fr>
 532
 533         * src/output.c (output_parser): Compute the `#line' lines when
 534         there are.
 535         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
 536         Suggested by Hans Aberg.
 537
 538 2000-12-19  Akim Demaille  <akim@epita.fr>
 539
 540         Let the handling of the skeleton files be local to the procedures
 541         that use it.
 542
 543         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
 544         longer static.
 545         (fparser, open_extra_files): Remove.
 546         (open_files, output_files): Don't take care of fparser.

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

 558 2000-12-19  Akim Demaille  <akim@epita.fr>
 559
 560         * src/files.c (open_files): Yipee!  We no longer need all the code
 561         looking for `/tmp' since we have no tmp file.
 562
 563 2000-12-19  Akim Demaille  <akim@epita.fr>
 564
 565         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 566         New macros.
 567         * src/files.c (open_files): Less dependency on MSDOS etc.

 580         (copy_guard): Quote the file names.
 581         Reported by Laurent Mascherpa.
 582
 583 2000-12-12  Akim Demaille  <akim@epita.fr>

 591
 592         * lib/obstack.h: Formatting changes.
 593         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 594         prevents type checking.
 595         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 596         cast the value to (void *): assigning a `foo *' to a `void *'
 597         variable is valid.
 598         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 599         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
 600         append characters.
 601

 615
 616         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
 617         macros.

 634
 635 2000-11-07  Akim Demaille  <akim@epita.fr>
 636
 637         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

 647         `address' for consistency.  Qualify it `const'.

 649         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
 650         `const' their input argument (`data' or `address').
 651         Adjust the corresponding macros to include `const' in casts.

 660
 661         For some reason, this was not applied.
 662
 663         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 678         Use `obstack_save'.
 679         * src/main.c (main): Don't use `atexit' to register `done', since
 680         it no longer has to remove tmp files, just call `output_files'
 681         when there are no errors.
 682

 755         (copy_comment, copy_definition, parse_union_decl, copy_action)
 756         (copy_guard): Adjust.

 785
 786         When a literal string is used to define two different tokens,
 787         `bison -v' segfaults.
 788         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 789
 790         * tests/regression.m4: New file.
 791         Include the core of the sample provided by Piotr Gackiewicz.

 800
 801 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 802
 803         * bison.s1 (yyparse): Assign the default value
 804         unconditionally, to avoid a GCC warning and make the parser a
 805         tad smaller.
 806
 807 2000-10-02  Akim Demaille  <akim@epita.fr>
 808
 809         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
 810         options.

 813
 814         * src/derives.c, src/print.c, src/reduce.c: To ease the

 816
 817 2000-10-02  Akim Demaille  <akim@epita.fr>
 818
 819         The location tracking mechanism is precious for parse error
 820         messages.  Nevertheless, it is enabled only when `@n' is used in
 821         the grammar, which is a different issue (you can use it in error
 822         message, but not in the grammar per se).  Therefore, there should
 823         be another means to enable it.
 824
 825         * src/getargs.c (getargs): Support `--locations'.
 826         (usage): Report it.
 827         * src/getargs.h (locationsflag): Export it.
 828         * src/lex.c (percent_table): Support `%locations'.
 829         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 830         with `locationsflag'.
 831         * doc/bison.texinfo: Document `--locations' and `%locations'.
 832         Sort the options.
 833         * tests/calc.m4: Test it.
 834
 835         For regularity of the names, replace each
 836         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 837         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 838         In addition replace each `flag' with `_flag'.
 839
 840 2000-10-02  Akim Demaille  <akim@epita.fr>
 841
 842         Also test parse error messages, including with YYERROR_VERBOSE.
 843
 844         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 845         associative).
 846         Use it to check the computations.
 847         Use it to check `nonassoc' is honored.
 848         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 849         `--yyerror-verbose'.
 850         (_AT_CHECK_CALC): Adjust to this option.
 851         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 852
 853 2000-10-02  Akim Demaille  <akim@epita.fr>
 854
 855         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 856         the latter demonstrates a flaw in the handling of non debugging
 857         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 858         was used in order to simplify:
 859
 860         #if YYDEBUG
 861         if (yydebug)
 862         {
 863         ...
 864         }
 865         #endif
 866
 867         into
 868
 869         if (yydebug)
 870         {
 871         ...
 872         }
 873
 874         unfortunately this leads to a CPP conflict when
 875         `--name-prefix=foo' is used since it produces `#define yydebug
 876         foodebug'.
 877
 878         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 879         (YYDPRINTF): New macro.
 880         Spread its use.
 881         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 882         the bison options.
 883         Also test `--verbose', `--defines' and `--name-prefix'.
 884
 885 2000-10-02  Akim Demaille  <akim@epita.fr>
 886
 887         Improve the readability of the produced parsers.
 888
 889         * src/bison.s1: Formatting changes.
 890         Improve the comment related to the `$' mark.
 891         (yydefault): Don't fall through to `yyresume': `goto' there.
 892         * src/output.c (output_parser): When the `$' is met, skip the end
 893         of its line.
 894         New variable, `number_of_dollar_signs', to check there's exactly
 895         one `$' in the parser skeleton.
 896
 897 2000-10-02  Akim Demaille  <akim@epita.fr>
 898
 899         * lib/xstrdup.c: New file, from the fileutils.
 900         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 901         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 902         instead of strlen + xmalloc + strcpy.
 903         * src/symtab.c (copys): Remove, use xstrdup instead.
 904
 905 2000-10-02  Akim Demaille  <akim@epita.fr>
 906
 907         * src/gram.h (associativity): New enum type which replaces the
 908         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 909         `right_assoc', `left_assoc' and `non_assoc'.
 910         Adjust all dependencies.
 911         * src/reader.c: Formatting changes.
 912         (LTYPESTR): Don't define it, use it as a literal in
 913         `reader_output_yylsp'.
 914         * src/symtab.h (symbol_class): New enum type which replaces the
 915         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 916         `sunknown', `stoken and `snterm'.
 917
 918 2000-10-02  Akim Demaille  <akim@epita.fr>
 919
 920         * src/getargs.c (fixed_outfiles): Rename as...
 921         (yaccflag): for consistency and accuracy.
 922         Adjust dependencies.
 923
 924 2000-10-02  Akim Demaille  <akim@epita.fr>
 925
 926         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 927         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 928         difficult and introduced a lot of core dump.  It turns out that
 929         Bison used an implementation of `xmalloc' based on `calloc', and
 930         at various places it does depend upon the initialization to 0.  I
 931         have not tried to isolate the pertinent places, and all the former
 932         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 933         someone should address this issue.
 934
 935         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 936         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 937         files.
 938         Adjust dependencies.
 939         * src/warshall.h: New file.
 940         Propagate.

 942 2000-10-02  Akim Demaille  <akim@epita.fr>

 947
 948 2000-10-02  Akim Demaille  <akim@epita.fr>
 949
 950         * src/state.h (nstates, final_state, first_state, first_shift)
 951         (first_reduction): Move their exportation from here...
 952         * src/LR0.h: to here.
 953         Adjust dependencies.
 954         * src/getargs.c (statisticsflag): New variable.
 955         Add support for `--statistics'.

1005
1006 2000-10-02  Akim Demaille  <akim@epita.fr>
1007
1008         * src/reader.h: New file.
1009         Propagate its use instead of tedious list of `extern' and

1027
1028 2000-10-02  Akim Demaille  <akim@epita.fr>
1029
1030         * src/output.c (token_actions): Introduce a temporary array,
1031         YYDEFACT, that makes it possible for this function to use
1032         output_short_table.
1033
1034 2000-10-02  Akim Demaille  <akim@epita.fr>
1035
1036         `user_toknums' is output as a `short[]' in `output.c', while it is
1037         defined as a `int[]' in `reader.c'.  For consistency with the
1038         other output tables, `user_toknums' is now defined as a table of
1039         shorts.
1040
1041         * src/reader.c (user_toknums): Be a short table instead of an int
1042         table.

1052
1053         * src/output.c (output): Topological sort of the functions, in
1054         order to get rid of the `static' prototypes.
1055         No longer use `register'.
1056         * src/output.h: New file.
1057         Propagate its inclusion in files explicitly prototyping functions
1058         from output.c.

1080         inclusion.
1081         Don't define PARAMS.
1082         * src/system.h: Define PARAMS.
1083         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

1110         Let all `extern' declarations about getargs.c be replaced with

1248
1249 2000-03-17  Akim Demaille  <akim@epita.fr>
1250
1251         On syntax errors, report the token on which we choked.

1273         copy_comment.  Removed now unused `match', `ended',
1274         `cplus_comment'.
1275         (copy_comment, copy_string): Moved, to be visible from
1276         copy_definition.
1277

1279

1302
1303         Change the handling of @s so that they behave exactly like $s.
1304         There is now a pseudo variable @$ (readble and writable), location
1305         of the lhs of the rule (by default ranging from the location of
1306         the first symbol of the rhs, to the location of the last symbol,
1307         or, if the rhs is empty, YYLLOC).
1308
1309         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1310         yyval.
1311         (yyparse): When providing a default semantic action, provide a
1312         default location action.
1313         (after the $): No longer change `*YYLSP', just stack YYLOC the
1314         same way you stack YYVAL.
1315         * src/reader.c (read_declarations): Use warns.
1316         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1317         (copy_action, case '@'): Likewise.
1318         Use a standard error message, to save useless work from
1319         translators.
1320
1321 2000-03-17  Akim Demaille  <akim@epita.fr>
1322

1340
1341         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1342         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1343         One `#if YYDEBUG' remains, since it uses variables which are
1344         defined only if `YYDEBUG != 0'.
1345
1346 2000-03-16  Akim Demaille  <akim@epita.fr>

1372         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

1378         the proper line number and file name.
1379         (DEFS): Propagate the location of bison library files and of the
1380         locale files.
1381         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1382         builddir.
1383         * acinclude.m4: Remove, replaced by the directory m4.
1384         * m4/Makefile.am (EXTRA_DIST): New variable.
1385         * m4/gettext.m4: New file, from the fileutils.
