 384 2001-03-16  Akim Demaille  <akim@epita.fr>
 385
 386         * getargs.c (skeleton): New variable.
 387         (longopts): --skeleton is a new option.
 388         (shortopts, getargs): -S is a new option.
 389         * getargs.h: Declare skeleton.
 390         * output.c (output_parser): Use it.
 391
 392 2001-03-16  Akim Demaille  <akim@epita.fr>
 393
 394         * m4/strerror_r.m4: New.

 397
 398 2001-03-16  Akim Demaille  <akim@epita.fr>
 399
 400         * src/getargs.c (longopts): Clean up.
 401
 402 2001-02-21  Akim Demaille  <akim@epita.fr>
 403
 404         * src/reader.c (gensym): `gensym_count' is your own.
 405         Use a static buf to create the symbol name, as token_buffer is no
 406         longer a buffer.
 407
 408 2001-02-08  Akim Demaille  <akim@epita.fr>
 409
 410         * src/conflicts.c (conflict_report): Be sure not to append to res
 411         between two calls, which could happen if both first sprintf were
 412         skipped, but not the first cp += strlen.
 413
 414 2001-02-08  Akim Demaille  <akim@epita.fr>
 415
 416         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
 417         New, from fileutils 4.0.37.
 418         * configure.in: Require Autoconf 2.49c.  I took some time before
 419         making this decision.  This is the only way out for portability
 420         issues in Bison, it would mean way too much duplicate effort to
 421         import in Bison features implemented in 2.49c since 2.13.
 422         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
 423
 424 2001-02-02  Akim Demaille  <akim@epita.fr>
 425
 426         * lib/malloc.c, lib/realloc.c: New, from the fileutils 4.0.37.

 430
 431         Get rid of the ad hoc handling of token_buffer in the scanner: use
 432         the obstacks.
 433
 434         * src/lex.c (token_obstack): New.
 435         (init_lex): Initialize it.  No longer call...
 436         (grow_token_buffer): this.  Remove it.
 437         Adjust all the places which used it to use the obstack.
 438
 439 2001-01-19  Akim Demaille  <akim@epita.fr>
 440
 441         * src/lex.h: Rename all the tokens:
 442         s/\bENDFILE\b/tok_eof/g;
 443         s/\bIDENTIFIER\b/tok_identifier/g;
 444         etc.
 445         Let them be enums, not #define, to ease debugging.
 446         Adjust all the code.
 447
 448 2001-01-18  Akim Demaille  <akim@epita.fr>
 449
 450         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 451         * src/lex.c (maxtoken, grow_token_buffer): Static.
 452
 453 2001-01-18  Akim Demaille  <akim@epita.fr>
 454
 455         Since we now use obstacks, more % directives can be enabled.
 456
 457         * src/lex.c (percent_table): Also accept `%yacc',
 458         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 459         `%debug'.
 460         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 461         instead of returning a token.
 462         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 463         * src/reader.c (read_declarations): Adjust.
 464         * src/files.c (open_files): Don't call `compute_base_names', don't
 465         compute `attrsfile' since they depend upon data which might be
 466         *in* the input file now.
 467         (output_files): Do it here.
 468         * src/output.c (output_headers): Document the fact that this patch
 469         introduces a guaranteed SEGV for semantic parsers.
 470         * doc/bison.texinfo: Document them.
 471         * tests/suite.at: Exercise these %options.
 472
 473 2000-12-20  Akim Demaille  <akim@epita.fr>
 474
 475         Also handle the output file (--verbose) with obstacks.

 479         Adjust all dependencies.

 481         * src/system.h (obstack_grow_string): Rename as...
 482         (obstack_sgrow): this.  Be ready to work with non literals.
 483         (obstack_fgrow4): New.
 484
 485 2000-12-20  Akim Demaille  <akim@epita.fr>
 486
 487         * src/files.c (open_files): Fix the computation of short_base_name
 488         in the case of `-o foo.tab.c'.
 489
 490 2000-12-20  Akim Demaille  <akim@epita.fr>
 491
 492         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 493         (copy_dollar): Now that everything uses obstacks, get rid of the
 494         FILE * parameters.
 495
 496 2000-12-20  Akim Demaille  <akim@epita.fr>
 497
 498         * src/files.c (open_files): Actually the `.output' file is based
 499         on the short_base_name, not base_name.
 500         * tests/suite.at (Checking output file names): Adjust.
 501
 502 2000-12-20  Akim Demaille  <akim@epita.fr>

 505         * src/bison.simple: this.
 506         * src/Makefile.am: Use pkgdata instead of data.
 507
 508 2000-12-20  Akim Demaille  <akim@epita.fr>
 509
 510         * src/files.c (guard_obstack): New.

 519         vars.
 520         (open_files): Don't compute them.

 526
 527         * src/files.c (strsuffix): New.
 528         (stringappend): Be just like strcat but allocate.
 529         (base_names): Eve out from open_files.
 530         Try to simplify the rather hairy computation of base_name and
 531         short_base_name.
 532         (open_files): Use it.
 533         * tests/suite.at (Checking output file names): New test.
 534
 535 2000-12-19  Akim Demaille  <akim@epita.fr>

 539         * src/output.c (output_parser): Recognize `%% actions' instead of
 540         `$'.
 541         * src/bison.s1: s/$/%% actions/.
 542         * src/bison.hairy: Likewise.
 543
 544 2000-12-19  Akim Demaille  <akim@epita.fr>
 545
 546         * src/output.c (output_parser): Compute the `#line' lines when
 547         there are.
 548         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
 549         Suggested by Hans Aberg.
 550
 551 2000-12-19  Akim Demaille  <akim@epita.fr>
 552
 553         Let the handling of the skeleton files be local to the procedures
 554         that use it.
 555
 556         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
 557         longer static.
 558         (fparser, open_extra_files): Remove.
 559         (open_files, output_files): Don't take care of fparser.

 566 2000-12-19  Akim Demaille  <akim@epita.fr>
 567
 568         * src/file.h (BISON_SIMPLE, BISON_HAIRY): Move from here...

 571 2000-12-19  Akim Demaille  <akim@epita.fr>
 572
 573         * src/files.c (open_files): Yipee!  We no longer need all the code
 574         looking for `/tmp' since we have no tmp file.
 575
 576 2000-12-19  Akim Demaille  <akim@epita.fr>
 577
 578         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 579         New macros.
 580         * src/files.c (open_files): Less dependency on MSDOS etc.

 593         (copy_guard): Quote the file names.
 594         Reported by Laurent Mascherpa.
 595
 596 2000-12-12  Akim Demaille  <akim@epita.fr>

 604
 605         * lib/obstack.h: Formatting changes.
 606         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 607         prevents type checking.
 608         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 609         cast the value to (void *): assigning a `foo *' to a `void *'
 610         variable is valid.
 611         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 612         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
 613         append characters.
 614
 615 2000-11-17  Akim Demaille  <akim@epita.fr>
 616
 617         * tests/Makefile.am (suite.m4, regression.m4, calc.m4): Rename

 628
 629         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
 630         macros.

 647
 648 2000-11-07  Akim Demaille  <akim@epita.fr>
 649
 650         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
 651         Merge in a single CPP if/else.
 652
 653 2000-11-07  Akim Demaille  <akim@epita.fr>
 654

 660         `address' for consistency.  Qualify it `const'.
 661         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 662         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
 663         `const' their input argument (`data' or `address').
 664         Adjust the corresponding macros to include `const' in casts.

 667
 668         * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

 671
 672 2000-11-03  Akim Demaille  <akim@epita.fr>
 673
 674         For some reason, this was not applied.
 675
 676         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 690         (output_files): this.
 691         Use `obstack_save'.
 692         * src/main.c (main): Don't use `atexit' to register `done', since
 693         it no longer has to remove tmp files, just call `output_files'
 694         when there are no errors.
 695
 696 2000-11-02  Akim Demaille  <akim@epita.fr>

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

 799         When a literal string is used to define two different tokens,
 800         `bison -v' segfaults.
 801         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 802
 803         * tests/regression.m4: New file.
 804         Include the core of the sample provided by Piotr Gackiewicz.

 813
 814 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 815
 816         * bison.s1 (yyparse): Assign the default value
 817         unconditionally, to avoid a GCC warning and make the parser a
 818         tad smaller.
 819
 820 2000-10-02  Akim Demaille  <akim@epita.fr>
 821
 822         * src/getargs.c (getargs): Don't dump `--help' on unrecognized

 826
 827         * src/derives.c, src/print.c, src/reduce.c: To ease the

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

 935         Adjust dependencies.
 936
 937 2000-10-02  Akim Demaille  <akim@epita.fr>
 938
 939         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 940         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 941         difficult and introduced a lot of core dump.  It turns out that
 942         Bison used an implementation of `xmalloc' based on `calloc', and
 943         at various places it does depend upon the initialization to 0.  I
 944         have not tried to isolate the pertinent places, and all the former
 945         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 946         someone should address this issue.
 947
 948         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 949         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 950         files.
 951         Adjust dependencies.

 961 2000-10-02  Akim Demaille  <akim@epita.fr>
 962
 963         * src/state.h (nstates, final_state, first_state, first_shift)
 964         (first_reduction): Move their exportation from here...
 965         * src/LR0.h: to here.
 966         Adjust dependencies.

1041 2000-10-02  Akim Demaille  <akim@epita.fr>
1042
1043         * src/output.c (token_actions): Introduce a temporary array,

1045         output_short_table.
1046
1047 2000-10-02  Akim Demaille  <akim@epita.fr>
1048
1049         `user_toknums' is output as a `short[]' in `output.c', while it is
1050         defined as a `int[]' in `reader.c'.  For consistency with the
1051         other output tables, `user_toknums' is now defined as a table of
1052         shorts.
1053
1054         * src/reader.c (user_toknums): Be a short table instead of an int

1067         order to get rid of the `static' prototypes.
1068         No longer use `register'.
1069         * src/output.h: New file.

1094         Don't define PARAMS.
1095         * src/system.h: Define PARAMS.
1096         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

1235         * configure.in: Adjust.
1236         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

1261
1262 2000-03-17  Akim Demaille  <akim@epita.fr>
1263
1264         On syntax errors, report the token on which we choked.
1265
1266         * src/bison.s1 (yyparse): In the label yyerrlab, when

1284

1286         copy_comment.  Removed now unused `match', `ended',
1287         `cplus_comment'.
1288         (copy_comment, copy_string): Moved, to be visible from
1289         copy_definition.
1290

1292
1293         * src/reader.c (copy_string): Declare `static inline'.  No

1315
1316         Change the handling of @s so that they behave exactly like $s.
1317         There is now a pseudo variable @$ (readble and writable), location
1318         of the lhs of the rule (by default ranging from the location of
1319         the first symbol of the rhs, to the location of the last symbol,
1320         or, if the rhs is empty, YYLLOC).
1321
1322         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1323         yyval.
1324         (yyparse): When providing a default semantic action, provide a
1325         default location action.
1326         (after the $): No longer change `*YYLSP', just stack YYLOC the
1327         same way you stack YYVAL.
1328         * src/reader.c (read_declarations): Use warns.
1329         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1330         (copy_action, case '@'): Likewise.
1331         Use a standard error message, to save useless work from
1332         translators.
1333
1334 2000-03-17  Akim Demaille  <akim@epita.fr>
1335
1336         * src/bison.s1: Formatting and cosmetics changes.

1353
1354         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1355         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1356         One `#if YYDEBUG' remains, since it uses variables which are
1357         defined only if `YYDEBUG != 0'.
1358
1359 2000-03-16  Akim Demaille  <akim@epita.fr>
1360
1361         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

1385         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

1391         the proper line number and file name.
1392         (DEFS): Propagate the location of bison library files and of the
1393         locale files.
1394         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1395         builddir.
1396         * acinclude.m4: Remove, replaced by the directory m4.
1397         * m4/Makefile.am (EXTRA_DIST): New variable.
1398         * m4/gettext.m4: New file, from the fileutils.
