   6
   7 2001-08-28  Pascal Bart  <pascal.bart@epita.fr>
   8
   9         * src/output.c (output): Copy attrs_obstack in the '%%definitions'
  10         directive.

  14
  15         * config/depcomp: New file.
  16
  17 2001-08-27  Paul Eggert  <eggert@twinsun.com>
  18
  19         * src/bison.simple (yyparse): Don't take the address of an
  20         item before the start of an array, as that doesn't conform to
  21         the C Standard.
  22
  23 2001-08-27  Robert Anisko  <robert.anisko@epita.fr>
  24
  25         * src/output.c (output): Remove the initialization of the macro
  26         obstack.  It was done too late here.

  29         completely wrong.

  33         * src/reader.h: Declare the macro obstack as extern.
  34
  35 2001-08-27  Robert Anisko  <robert.anisko@epita.fr>

  68         bound to true.
  69         (read_declarations): Add case for macro definition.

 104
 105         * src/output.c (output_parser): Replace most of the skeleton copy code
 106         with something new. Skeletons are now processed character by character
 107         rather than line by line, and Bison looks for '%%' macros. This is the
 108         first step in making Bison's output process (a lot) more flexible.

 392         * config/prev-version.txt, config/move-if-change: New.
 393         * Makefile.am: Adjust.
 394
 395 2001-07-08  Pascal Bart  <pascal.bart@epita.fr>
 396
 397         * src/bison.simple (yyparse): Suppress warning `comparaison
 398         between signed and unsigned'.
 399
 400 2001-07-05  Pascal Bart  <pascal.bart@epita.fr>
 401
 402         * src/getargs.h (raw_flag): Remove.
 403         * src/getargs.c: Die on `-r'/`--raw'.
 404         * src/lex.c (parse_percent_token): Die on `%raw'.
 405         * src/reader.c (output_token_defines): Suppress call to `raw_flag'.
 406         * tests/calc.at: Suppress test with option `--raw'.
 407
 408 2001-07-14  Akim Demaille  <akim@epita.fr>
 409
 410         * config/: New.
 411         * configure.in: Require Autoconf 2.50.
 412         Update to gettext 0.10.38.
 413
 414 2001-03-16  Akim Demaille  <akim@epita.fr>
 415
 416         * doc/bison.texinfo: ANSIfy the examples.
 417
 418 2001-03-16  Akim Demaille  <akim@epita.fr>
 419
 420         * getargs.c (skeleton): New variable.
 421         (longopts): --skeleton is a new option.
 422         (shortopts, getargs): -S is a new option.
 423         * getargs.h: Declare skeleton.
 424         * output.c (output_parser): Use it.
 425
 426 2001-03-16  Akim Demaille  <akim@epita.fr>
 427
 428         * m4/strerror_r.m4: New.

 431
 432 2001-03-16  Akim Demaille  <akim@epita.fr>
 433
 434         * src/getargs.c (longopts): Clean up.
 435
 436 2001-02-21  Akim Demaille  <akim@epita.fr>
 437
 438         * src/reader.c (gensym): `gensym_count' is your own.
 439         Use a static buf to create the symbol name, as token_buffer is no
 440         longer a buffer.
 441
 442 2001-02-08  Akim Demaille  <akim@epita.fr>
 443
 444         * src/conflicts.c (conflict_report): Be sure not to append to res
 445         between two calls, which could happen if both first sprintf were
 446         skipped, but not the first cp += strlen.
 447
 448 2001-02-08  Akim Demaille  <akim@epita.fr>
 449
 450         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
 451         New, from fileutils 4.0.37.
 452         * configure.in: Require Autoconf 2.49c.  I took some time before
 453         making this decision.  This is the only way out for portability
 454         issues in Bison, it would mean way too much duplicate effort to
 455         import in Bison features implemented in 2.49c since 2.13.
 456         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
 457
 458 2001-02-02  Akim Demaille  <akim@epita.fr>
 459
 460         * lib/malloc.c, lib/realloc.c: New, from the fileutils 4.0.37.

 462
 463 2001-01-19  Akim Demaille  <akim@epita.fr>
 464
 465         Get rid of the ad hoc handling of token_buffer in the scanner: use
 466         the obstacks.
 467
 468         * src/lex.c (token_obstack): New.
 469         (init_lex): Initialize it.  No longer call...
 470         (grow_token_buffer): this.  Remove it.
 471         Adjust all the places which used it to use the obstack.
 472
 473 2001-01-19  Akim Demaille  <akim@epita.fr>
 474
 475         * src/lex.h: Rename all the tokens:
 476         s/\bENDFILE\b/tok_eof/g;
 477         s/\bIDENTIFIER\b/tok_identifier/g;
 478         etc.
 479         Let them be enums, not #define, to ease debugging.
 480         Adjust all the code.
 481
 482 2001-01-18  Akim Demaille  <akim@epita.fr>
 483
 484         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 485         * src/lex.c (maxtoken, grow_token_buffer): Static.
 486
 487 2001-01-18  Akim Demaille  <akim@epita.fr>
 488
 489         Since we now use obstacks, more % directives can be enabled.
 490
 491         * src/lex.c (percent_table): Also accept `%yacc',
 492         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 493         `%debug'.
 494         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 495         instead of returning a token.
 496         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 497         * src/reader.c (read_declarations): Adjust.
 498         * src/files.c (open_files): Don't call `compute_base_names', don't
 499         compute `attrsfile' since they depend upon data which might be
 500         *in* the input file now.
 501         (output_files): Do it here.
 502         * src/output.c (output_headers): Document the fact that this patch
 503         introduces a guaranteed SEGV for semantic parsers.
 504         * doc/bison.texinfo: Document them.
 505         * tests/suite.at: Exercise these %options.
 506
 507 2000-12-20  Akim Demaille  <akim@epita.fr>
 508
 509         Also handle the output file (--verbose) with obstacks.
 510
 511         * files.c (foutput): Remove.
 512         (output_obstack): New.
 513         Adjust all dependencies.
 514         * src/conflicts.c: Return a string.
 515         * src/system.h (obstack_grow_string): Rename as...
 516         (obstack_sgrow): this.  Be ready to work with non literals.
 517         (obstack_fgrow4): New.
 518
 519 2000-12-20  Akim Demaille  <akim@epita.fr>
 520
 521         * src/files.c (open_files): Fix the computation of short_base_name
 522         in the case of `-o foo.tab.c'.
 523
 524 2000-12-20  Akim Demaille  <akim@epita.fr>
 525
 526         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 527         (copy_dollar): Now that everything uses obstacks, get rid of the
 528         FILE * parameters.
 529
 530 2000-12-20  Akim Demaille  <akim@epita.fr>
 531
 532         * src/files.c (open_files): Actually the `.output' file is based
 533         on the short_base_name, not base_name.
 534         * tests/suite.at (Checking output file names): Adjust.
 535
 536 2000-12-20  Akim Demaille  <akim@epita.fr>
 537
 538         * src/bison.s1: Remove, we now use directly...
 539         * src/bison.simple: this.
 540         * src/Makefile.am: Use pkgdata instead of data.
 541
 542 2000-12-20  Akim Demaille  <akim@epita.fr>
 543
 544         * src/files.c (guard_obstack): New.

 549
 550 2000-12-19  Akim Demaille  <akim@epita.fr>
 551
 552         * src/files.c (outfile, defsfile, actfile): Removed as global
 553         vars.
 554         (open_files): Don't compute them.
 555         (output_files): Adjust.
 556         (base_name, short_base_name): Be global.
 557         Adjust dependencies.
 558
 559 2000-12-19  Akim Demaille  <akim@epita.fr>
 560
 561         * src/files.c (strsuffix): New.
 562         (stringappend): Be just like strcat but allocate.
 563         (base_names): Eve out from open_files.
 564         Try to simplify the rather hairy computation of base_name and
 565         short_base_name.
 566         (open_files): Use it.
 567         * tests/suite.at (Checking output file names): New test.
 568
 569 2000-12-19  Akim Demaille  <akim@epita.fr>
 570
 571         * src/system.h (obstack_grow_literal_string): Rename as...
 572         (obstack_grow_string): this.
 573         * src/output.c (output_parser): Recognize `%% actions' instead of
 574         `$'.
 575         * src/bison.s1: s/$/%% actions/.
 576         * src/bison.hairy: Likewise.
 577
 578 2000-12-19  Akim Demaille  <akim@epita.fr>
 579
 580         * src/output.c (output_parser): Compute the `#line' lines when
 581         there are.
 582         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
 583         Suggested by Hans Aberg.
 584
 585 2000-12-19  Akim Demaille  <akim@epita.fr>
 586
 587         Let the handling of the skeleton files be local to the procedures
 588         that use it.
 589
 590         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
 591         longer static.
 592         (fparser, open_extra_files): Remove.
 593         (open_files, output_files): Don't take care of fparser.
 594         * src/files.h: Adjust.

 600 2000-12-19  Akim Demaille  <akim@epita.fr>
 601
 602         * src/file.h (BISON_SIMPLE, BISON_HAIRY): Move from here...

 604
 605 2000-12-19  Akim Demaille  <akim@epita.fr>
 606
 607         * src/files.c (open_files): Yipee!  We no longer need all the code
 608         looking for `/tmp' since we have no tmp file.
 609
 610 2000-12-19  Akim Demaille  <akim@epita.fr>
 611
 612         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 613         New macros.
 614         * src/files.c (open_files): Less dependency on MSDOS etc.

 624 2000-12-12  Akim Demaille  <akim@epita.fr>
 625
 626         * src/reader.c (copy_definition, parse_union_decl, copy_action)
 627         (copy_guard): Quote the file names.
 628         Reported by Laurent Mascherpa.
 629
 630 2000-12-12  Akim Demaille  <akim@epita.fr>
 631

 636
 637 2000-11-17  Akim Demaille  <akim@epita.fr>
 638
 639         * lib/obstack.h: Formatting changes.
 640         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 641         prevents type checking.
 642         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 643         cast the value to (void *): assigning a `foo *' to a `void *'
 644         variable is valid.
 645         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 646         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
 647         append characters.
 648
 649 2000-11-17  Akim Demaille  <akim@epita.fr>
 650
 651         * tests/Makefile.am (suite.m4, regression.m4, calc.m4): Rename

 659         demonstrating a current bug in the obstack implementation.
 660
 661 2000-11-17  Akim Demaille  <akim@epita.fr>
 662
 663         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
 664         macros.
 665         Use them to declare the variables which are global or local to

 679         defining.
 680         * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
 681
 682 2000-11-07  Akim Demaille  <akim@epita.fr>
 683
 684         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
 685         Merge in a single CPP if/else.
 686
 687 2000-11-07  Akim Demaille  <akim@epita.fr>
 688
 689         * src/output.c (output): Remove useless variables.
 690         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
 691         argument `data' for consistency with the prototypes.
 692         Qualify it `const'.
 693         (obstack_copy, obstack_copy0): Rename the second argument as
 694         `address' for consistency.  Qualify it `const'.
 695         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 696         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
 697         `const' their input argument (`data' or `address').
 698         Adjust the corresponding macros to include `const' in casts.
 699
 700 2000-11-03  Akim Demaille  <akim@epita.fr>
 701
 702         * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
 703         s/PFILE1/BISON_HAIRY/.
 704         Adjust dependencies.
 705
 706 2000-11-03  Akim Demaille  <akim@epita.fr>
 707
 708         For some reason, this was not applied.
 709
 710         * src/files.c [VMS]: No longer include `ssdef.h', no longer define
 711         `unlink': it's no longer used.

 714
 715         * src/files.c (skeleton_find): New function, eved out of...

 717
 718 2000-11-03  Akim Demaille  <akim@epita.fr>
 719
 720         Don't use `atexit'.

 723         (done): Rename as...
 724         (output_files): this.
 725         Use `obstack_save'.
 726         * src/main.c (main): Don't use `atexit' to register `done', since
 727         it no longer has to remove tmp files, just call `output_files'
 728         when there are no errors.
 729
 730 2000-11-02  Akim Demaille  <akim@epita.fr>
 731

 741         (defines_ostack, table_obstack): New.
 742         Adjust dependencies of the former into uses of the latter.

 744         Convert to using obstacks.

 800         the `/' which is suspected to open a comment, instead of being
 801         called after `//' or `/*' was read.
 802         (copy_comment, copy_definition, parse_union_decl, copy_action)
 803         (copy_guard): Adjust.

 833         When a literal string is used to define two different tokens,
 834         `bison -v' segfaults.
 835         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 836
 837         * tests/regression.m4: New file.

 848 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 849
 850         * bison.s1 (yyparse): Assign the default value
 851         unconditionally, to avoid a GCC warning and make the parser a
 852         tad smaller.
 853
 854 2000-10-02  Akim Demaille  <akim@epita.fr>
 855

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

 863
 864 2000-10-02  Akim Demaille  <akim@epita.fr>
 865
 866         The location tracking mechanism is precious for parse error
 867         messages.  Nevertheless, it is enabled only when `@n' is used in
 868         the grammar, which is a different issue (you can use it in error
 869         message, but not in the grammar per se).  Therefore, there should
 870         be another means to enable it.
 871
 872         * src/getargs.c (getargs): Support `--locations'.
 873         (usage): Report it.
 874         * src/getargs.h (locationsflag): Export it.
 875         * src/lex.c (percent_table): Support `%locations'.
 876         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 877         with `locationsflag'.
 878         * doc/bison.texinfo: Document `--locations' and `%locations'.
 879         Sort the options.
 880         * tests/calc.m4: Test it.
 881
 882         For regularity of the names, replace each
 883         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 884         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 885         In addition replace each `flag' with `_flag'.
 886
 887 2000-10-02  Akim Demaille  <akim@epita.fr>
 888
 889         Also test parse error messages, including with YYERROR_VERBOSE.
 890
 891         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 892         associative).
 893         Use it to check the computations.
 894         Use it to check `nonassoc' is honored.
 895         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 896         `--yyerror-verbose'.
 897         (_AT_CHECK_CALC): Adjust to this option.
 898         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 899
 900 2000-10-02  Akim Demaille  <akim@epita.fr>
 901
 902         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 903         the latter demonstrates a flaw in the handling of non debugging
 904         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 905         was used in order to simplify:
 906
 907         #if YYDEBUG
 908         if (yydebug)
 909         {
 910         ...
 911         }
 912         #endif
 913
 914         into
 915
 916         if (yydebug)
 917         {
 918         ...
 919         }
 920
 921         unfortunately this leads to a CPP conflict when
 922         `--name-prefix=foo' is used since it produces `#define yydebug
 923         foodebug'.
 924
 925         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 926         (YYDPRINTF): New macro.
 927         Spread its use.
 928         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 929         the bison options.
 930         Also test `--verbose', `--defines' and `--name-prefix'.
 931
 932 2000-10-02  Akim Demaille  <akim@epita.fr>
 933
 934         Improve the readability of the produced parsers.
 935
 936         * src/bison.s1: Formatting changes.
 937         Improve the comment related to the `$' mark.
 938         (yydefault): Don't fall through to `yyresume': `goto' there.
 939         * src/output.c (output_parser): When the `$' is met, skip the end
 940         of its line.
 941         New variable, `number_of_dollar_signs', to check there's exactly
 942         one `$' in the parser skeleton.
 943
 944 2000-10-02  Akim Demaille  <akim@epita.fr>
 945
 946         * lib/xstrdup.c: New file, from the fileutils.
 947         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 948         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 949         instead of strlen + xmalloc + strcpy.
 950         * src/symtab.c (copys): Remove, use xstrdup instead.
 951
 952 2000-10-02  Akim Demaille  <akim@epita.fr>
 953
 954         * src/gram.h (associativity): New enum type which replaces the
 955         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 956         `right_assoc', `left_assoc' and `non_assoc'.
 957         Adjust all dependencies.
 958         * src/reader.c: Formatting changes.
 959         (LTYPESTR): Don't define it, use it as a literal in
 960         `reader_output_yylsp'.
 961         * src/symtab.h (symbol_class): New enum type which replaces the
 962         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 963         `sunknown', `stoken and `snterm'.
 964
 965 2000-10-02  Akim Demaille  <akim@epita.fr>
 966
 967         * src/getargs.c (fixed_outfiles): Rename as...

 969         Adjust dependencies.
 970
 971 2000-10-02  Akim Demaille  <akim@epita.fr>
 972
 973         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 974         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 975         difficult and introduced a lot of core dump.  It turns out that
 976         Bison used an implementation of `xmalloc' based on `calloc', and
 977         at various places it does depend upon the initialization to 0.  I
 978         have not tried to isolate the pertinent places, and all the former
 979         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 980         someone should address this issue.
 981
 982         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 983         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

1076
1077         * src/output.c (token_actions): Introduce a temporary array,

1079         output_short_table.
1080
1081 2000-10-02  Akim Demaille  <akim@epita.fr>
1082
1083         `user_toknums' is output as a `short[]' in `output.c', while it is
1084         defined as a `int[]' in `reader.c'.  For consistency with the
1085         other output tables, `user_toknums' is now defined as a table of
1086         shorts.
1087
1088         * src/reader.c (user_toknums): Be a short table instead of an int

1101         order to get rid of the `static' prototypes.
1102         No longer use `register'.
1103         * src/output.h: New file.

1129         * src/system.h: Define PARAMS.
1130         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

1295
1296 2000-03-17  Akim Demaille  <akim@epita.fr>
1297
1298         On syntax errors, report the token on which we choked.
1299
1300         * src/bison.s1 (yyparse): In the label yyerrlab, when

1318

1320         copy_comment.  Removed now unused `match', `ended',
1321         `cplus_comment'.
1322         (copy_comment, copy_string): Moved, to be visible from
1323         copy_definition.
1324

1326

1349
1350         Change the handling of @s so that they behave exactly like $s.
1351         There is now a pseudo variable @$ (readble and writable), location
1352         of the lhs of the rule (by default ranging from the location of
1353         the first symbol of the rhs, to the location of the last symbol,
1354         or, if the rhs is empty, YYLLOC).
1355
1356         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1357         yyval.
1358         (yyparse): When providing a default semantic action, provide a
1359         default location action.
1360         (after the $): No longer change `*YYLSP', just stack YYLOC the
1361         same way you stack YYVAL.
1362         * src/reader.c (read_declarations): Use warns.
1363         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1364         (copy_action, case '@'): Likewise.
1365         Use a standard error message, to save useless work from
1366         translators.
1367
1368 2000-03-17  Akim Demaille  <akim@epita.fr>
1369

1387
1388         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1389         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1390         One `#if YYDEBUG' remains, since it uses variables which are
1391         defined only if `YYDEBUG != 0'.
1392
1393 2000-03-16  Akim Demaille  <akim@epita.fr>
1394
1395         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

1425         the proper line number and file name.
1426         (DEFS): Propagate the location of bison library files and of the
1427         locale files.
1428         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1429         builddir.
1430         * acinclude.m4: Remove, replaced by the directory m4.
1431         * m4/Makefile.am (EXTRA_DIST): New variable.
1432         * m4/gettext.m4: New file, from the fileutils.
