 383 2001-03-16  Akim Demaille  <akim@epita.fr>
 384
 385         * m4/strerror_r.m4: New.

 388
 389 2001-03-16  Akim Demaille  <akim@epita.fr>
 390
 391         * src/getargs.c (longopts): Clean up.
 392
 393 2001-02-21  Akim Demaille  <akim@epita.fr>
 394
 395         * src/reader.c (gensym): `gensym_count' is your own.
 396         Use a static buf to create the symbol name, as token_buffer is no
 397         longer a buffer.
 398
 399 2001-02-08  Akim Demaille  <akim@epita.fr>
 400
 401         * src/conflicts.c (conflict_report): Be sure not to append to res
 402         between two calls, which could happen if both first sprintf were
 403         skipped, but not the first cp += strlen.
 404
 405 2001-02-08  Akim Demaille  <akim@epita.fr>
 406
 407         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
 408         New, from fileutils 4.0.37.
 409         * configure.in: Require Autoconf 2.49c.  I took some time before
 410         making this decision.  This is the only way out for portability
 411         issues in Bison, it would mean way too much duplicate effort to
 412         import in Bison features implemented in 2.49c since 2.13.
 413         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
 414
 415 2001-02-02  Akim Demaille  <akim@epita.fr>

 421
 422         Get rid of the ad hoc handling of token_buffer in the scanner: use
 423         the obstacks.
 424
 425         * src/lex.c (token_obstack): New.
 426         (init_lex): Initialize it.  No longer call...
 427         (grow_token_buffer): this.  Remove it.
 428         Adjust all the places which used it to use the obstack.
 429
 430 2001-01-19  Akim Demaille  <akim@epita.fr>
 431
 432         * src/lex.h: Rename all the tokens:
 433         s/\bENDFILE\b/tok_eof/g;
 434         s/\bIDENTIFIER\b/tok_identifier/g;
 435         etc.
 436         Let them be enums, not #define, to ease debugging.
 437         Adjust all the code.
 438
 439 2001-01-18  Akim Demaille  <akim@epita.fr>
 440
 441         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 442         * src/lex.c (maxtoken, grow_token_buffer): Static.
 443
 444 2001-01-18  Akim Demaille  <akim@epita.fr>
 445
 446         Since we now use obstacks, more % directives can be enabled.
 447
 448         * src/lex.c (percent_table): Also accept `%yacc',
 449         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 450         `%debug'.
 451         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 452         instead of returning a token.
 453         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 454         * src/reader.c (read_declarations): Adjust.
 455         * src/files.c (open_files): Don't call `compute_base_names', don't
 456         compute `attrsfile' since they depend upon data which might be
 457         *in* the input file now.
 458         (output_files): Do it here.
 459         * src/output.c (output_headers): Document the fact that this patch
 460         introduces a guaranteed SEGV for semantic parsers.
 461         * doc/bison.texinfo: Document them.
 462         * tests/suite.at: Exercise these %options.
 463

 470         Adjust all dependencies.

 472         * src/system.h (obstack_grow_string): Rename as...
 473         (obstack_sgrow): this.  Be ready to work with non literals.
 474         (obstack_fgrow4): New.
 475
 476 2000-12-20  Akim Demaille  <akim@epita.fr>
 477
 478         * src/files.c (open_files): Fix the computation of short_base_name
 479         in the case of `-o foo.tab.c'.
 480
 481 2000-12-20  Akim Demaille  <akim@epita.fr>
 482
 483         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 484         (copy_dollar): Now that everything uses obstacks, get rid of the
 485         FILE * parameters.
 486
 487 2000-12-20  Akim Demaille  <akim@epita.fr>
 488
 489         * src/files.c (open_files): Actually the `.output' file is based
 490         on the short_base_name, not base_name.
 491         * tests/suite.at (Checking output file names): Adjust.
 492
 493 2000-12-20  Akim Demaille  <akim@epita.fr>

 496         * src/bison.simple: this.
 497         * src/Makefile.am: Use pkgdata instead of data.
 498
 499 2000-12-20  Akim Demaille  <akim@epita.fr>
 500
 501         * src/files.c (guard_obstack): New.

 509         * src/files.c (outfile, defsfile, actfile): Removed as global
 510         vars.
 511         (open_files): Don't compute them.
 512         (output_files): Adjust.

 517
 518         * src/files.c (strsuffix): New.
 519         (stringappend): Be just like strcat but allocate.
 520         (base_names): Eve out from open_files.
 521         Try to simplify the rather hairy computation of base_name and
 522         short_base_name.
 523         (open_files): Use it.
 524         * tests/suite.at (Checking output file names): New test.
 525
 526 2000-12-19  Akim Demaille  <akim@epita.fr>

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

 557 2000-12-19  Akim Demaille  <akim@epita.fr>
 558
 559         * src/file.h (BISON_SIMPLE, BISON_HAIRY): Move from here...

 562 2000-12-19  Akim Demaille  <akim@epita.fr>
 563
 564         * src/files.c (open_files): Yipee!  We no longer need all the code
 565         looking for `/tmp' since we have no tmp file.
 566
 567 2000-12-19  Akim Demaille  <akim@epita.fr>
 568
 569         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 570         New macros.
 571         * src/files.c (open_files): Less dependency on MSDOS etc.

 584         (copy_guard): Quote the file names.
 585         Reported by Laurent Mascherpa.
 586
 587 2000-12-12  Akim Demaille  <akim@epita.fr>

 595
 596         * lib/obstack.h: Formatting changes.
 597         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 598         prevents type checking.
 599         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 600         cast the value to (void *): assigning a `foo *' to a `void *'
 601         variable is valid.
 602         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 603         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
 604         append characters.
 605

 619
 620         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
 621         macros.

 638
 639 2000-11-07  Akim Demaille  <akim@epita.fr>
 640
 641         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

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

 664
 665         For some reason, this was not applied.
 666
 667         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

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

 756         * src/reader.c (copy_comment2): Expect the input stream to be on
 757         the `/' which is suspected to open a comment, instead of being
 758         called after `//' or `/*' was read.
 759         (copy_comment, copy_definition, parse_union_decl, copy_action)
 760         (copy_guard): Adjust.

 790         When a literal string is used to define two different tokens,
 791         `bison -v' segfaults.
 792         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 793
 794         * tests/regression.m4: New file.
 795         Include the core of the sample provided by Piotr Gackiewicz.

 805 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 806
 807         * bison.s1 (yyparse): Assign the default value
 808         unconditionally, to avoid a GCC warning and make the parser a
 809         tad smaller.
 810
 811 2000-10-02  Akim Demaille  <akim@epita.fr>
 812
 813         * src/getargs.c (getargs): Don't dump `--help' on unrecognized

 817
 818         * src/derives.c, src/print.c, src/reduce.c: To ease the

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

 926         Adjust dependencies.
 927
 928 2000-10-02  Akim Demaille  <akim@epita.fr>
 929
 930         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 931         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 932         difficult and introduced a lot of core dump.  It turns out that
 933         Bison used an implementation of `xmalloc' based on `calloc', and
 934         at various places it does depend upon the initialization to 0.  I
 935         have not tried to isolate the pertinent places, and all the former
 936         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 937         someone should address this issue.
 938
 939         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 940         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 941         files.
 942         Adjust dependencies.

 951
 952 2000-10-02  Akim Demaille  <akim@epita.fr>
 953
 954         * src/state.h (nstates, final_state, first_state, first_shift)
 955         (first_reduction): Move their exportation from here...
 956         * src/LR0.h: to here.
 957         Adjust dependencies.

1032 2000-10-02  Akim Demaille  <akim@epita.fr>
1033
1034         * src/output.c (token_actions): Introduce a temporary array,
1035         YYDEFACT, that makes it possible for this function to use
1036         output_short_table.
1037
1038 2000-10-02  Akim Demaille  <akim@epita.fr>
1039
1040         `user_toknums' is output as a `short[]' in `output.c', while it is
1041         defined as a `int[]' in `reader.c'.  For consistency with the
1042         other output tables, `user_toknums' is now defined as a table of
1043         shorts.
1044
1045         * src/reader.c (user_toknums): Be a short table instead of an int
1046         table.

1058         order to get rid of the `static' prototypes.
1059         No longer use `register'.
1060         * src/output.h: New file.
1061         Propagate its inclusion in files explicitly prototyping functions
1062         from output.c.

1084         inclusion.
1085         Don't define PARAMS.
1086         * src/system.h: Define PARAMS.
1087         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
1088         purpose of config.h.  system.h must not try to fix wrong
1089         definitions in config.h.

1113         * src/getargs.h: New file.
1114         Let all `extern' declarations about getargs.c be replaced with

1251         the file name, not the whole `#line LINE FILE'.
1252
1253 2000-03-17  Akim Demaille  <akim@epita.fr>
1254
1255         On syntax errors, report the token on which we choked.
1256
1257         * src/bison.s1 (yyparse): In the label yyerrlab, when

1275

1277         copy_comment.  Removed now unused `match', `ended',
1278         `cplus_comment'.
1279         (copy_comment, copy_string): Moved, to be visible from
1280         copy_definition.
1281

1283
1284         * src/reader.c (copy_string): Declare `static inline'.  No

1306
1307         Change the handling of @s so that they behave exactly like $s.
1308         There is now a pseudo variable @$ (readble and writable), location
1309         of the lhs of the rule (by default ranging from the location of
1310         the first symbol of the rhs, to the location of the last symbol,
1311         or, if the rhs is empty, YYLLOC).
1312
1313         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1314         yyval.
1315         (yyparse): When providing a default semantic action, provide a
1316         default location action.
1317         (after the $): No longer change `*YYLSP', just stack YYLOC the
1318         same way you stack YYVAL.
1319         * src/reader.c (read_declarations): Use warns.
1320         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1321         (copy_action, case '@'): Likewise.
1322         Use a standard error message, to save useless work from
1323         translators.
1324
1325 2000-03-17  Akim Demaille  <akim@epita.fr>
1326

1344
1345         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1346         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1347         One `#if YYDEBUG' remains, since it uses variables which are
1348         defined only if `YYDEBUG != 0'.
1349
1350 2000-03-16  Akim Demaille  <akim@epita.fr>

1376         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

1382         the proper line number and file name.
1383         (DEFS): Propagate the location of bison library files and of the
1384         locale files.
1385         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1386         builddir.
1387         * acinclude.m4: Remove, replaced by the directory m4.
1388         * m4/Makefile.am (EXTRA_DIST): New variable.
1389         * m4/gettext.m4: New file, from the fileutils.
