  19         the VCG graph output.
  20         (print_actions): Unused code is now used. It notifies the final state
  21         and no action states in the VCG graph. It also give the reduce actions.
  22         The `shift and goto' edges are red and the `go to state' edges are
  23         blue.
  24         Get the current node name and node_obstack by argument.

  28         A node is not only computed here but in print_actions also.
  29         (print_graph): CPP out useless code instead of commenting it.

 220
 221 2001-02-21  Akim Demaille  <akim@epita.fr>
 222
 223         * src/reader.c (gensym): `gensym_count' is your own.
 224         Use a static buf to create the symbol name, as token_buffer is no

 228

 236         New, from fileutils 4.0.37.
 237         * configure.in: Require Autoconf 2.49c.  I took some time before
 238         making this decision.  This is the only way out for portability
 239         issues in Bison, it would mean way too much duplicate effort to
 240         import in Bison features implemented in 2.49c since 2.13.
 241         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
 242

 251         the obstacks.
 252
 253         * src/lex.c (token_obstack): New.
 254         (init_lex): Initialize it.  No longer call...
 255         (grow_token_buffer): this.  Remove it.
 256         Adjust all the places which used it to use the obstack.

 258 2001-01-19  Akim Demaille  <akim@epita.fr>
 259
 260         * src/lex.h: Rename all the tokens:
 261         s/\bENDFILE\b/tok_eof/g;
 262         s/\bIDENTIFIER\b/tok_identifier/g;
 263         etc.
 264         Let them be enums, not #define, to ease debugging.
 265         Adjust all the code.
 266
 267 2001-01-18  Akim Demaille  <akim@epita.fr>
 268
 269         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 270         * src/lex.c (maxtoken, grow_token_buffer): Static.
 271
 272 2001-01-18  Akim Demaille  <akim@epita.fr>
 273
 274         Since we now use obstacks, more % directives can be enabled.
 275
 276         * src/lex.c (percent_table): Also accept `%yacc',
 277         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 278         `%debug'.
 279         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 280         instead of returning a token.
 281         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 282         * src/reader.c (read_declarations): Adjust.
 283         * src/files.c (open_files): Don't call `compute_base_names', don't
 284         compute `attrsfile' since they depend upon data which might be
 285         *in* the input file now.
 286         (output_files): Do it here.
 287         * src/output.c (output_headers): Document the fact that this patch
 288         introduces a guaranteed SEGV for semantic parsers.

 300         * src/system.h (obstack_grow_string): Rename as...
 301         (obstack_sgrow): this.  Be ready to work with non literals.
 302         (obstack_fgrow4): New.
 303
 304 2000-12-20  Akim Demaille  <akim@epita.fr>

 311         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 312         (copy_dollar): Now that everything uses obstacks, get rid of the
 313         FILE * parameters.
 314
 315 2000-12-20  Akim Demaille  <akim@epita.fr>
 316
 317         * src/files.c (open_files): Actually the `.output' file is based
 318         on the short_base_name, not base_name.
 319         * tests/suite.at (Checking output file names): Adjust.
 320
 321 2000-12-20  Akim Demaille  <akim@epita.fr>

 324         * src/bison.simple: this.
 325         * src/Makefile.am: Use pkgdata instead of data.
 326
 327 2000-12-20  Akim Demaille  <akim@epita.fr>
 328
 329         * src/files.c (guard_obstack): New.

 347         (stringappend): Be just like strcat but allocate.
 348         (base_names): Eve out from open_files.
 349         Try to simplify the rather hairy computation of base_name and
 350         short_base_name.
 351         (open_files): Use it.
 352         * tests/suite.at (Checking output file names): New test.

 368         Suggested by Hans Aberg.
 369
 370 2000-12-19  Akim Demaille  <akim@epita.fr>
 371
 372         Let the handling of the skeleton files be local to the procedures
 373         that use it.
 374
 375         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
 376         longer static.

 384
 385 2000-12-19  Akim Demaille  <akim@epita.fr>
 386
 387         * src/file.h (BISON_SIMPLE, BISON_HAIRY): Move from here...

 389
 390 2000-12-19  Akim Demaille  <akim@epita.fr>
 391
 392         * src/files.c (open_files): Yipee!  We no longer need all the code
 393         looking for `/tmp' since we have no tmp file.
 394
 395 2000-12-19  Akim Demaille  <akim@epita.fr>
 396
 397         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 398         New macros.
 399         * src/files.c (open_files): Less dependency on MSDOS etc.
 400

 402
 403         * src/bison.s1 (YYLLOC_DEFAULT): New macro.
 404         Provide a default definition.
 405         Use it when executing the default @ action.
 406         * src/reader.c (reader_output_yylsp): No longer include
 407         `timestamp' and `text' in the default YYLTYPE.
 408
 409 2000-12-12  Akim Demaille  <akim@epita.fr>

 411         * src/reader.c (copy_definition, parse_union_decl, copy_action)
 412         (copy_guard): Quote the file names.
 413         Reported by Laurent Mascherpa.

 422 2000-11-17  Akim Demaille  <akim@epita.fr>
 423
 424         * lib/obstack.h: Formatting changes.
 425         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 426         prevents type checking.
 427         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 428         cast the value to (void *): assigning a `foo *' to a `void *'
 429         variable is valid.
 430         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 431         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
 432         append characters.

 447
 448         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
 449         macros.

 466
 467 2000-11-07  Akim Demaille  <akim@epita.fr>
 468
 469         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

 475         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
 476         argument `data' for consistency with the prototypes.
 477         Qualify it `const'.
 478         (obstack_copy, obstack_copy0): Rename the second argument as
 479         `address' for consistency.  Qualify it `const'.
 480         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 481         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

 489         Adjust dependencies.
 490
 491 2000-11-03  Akim Demaille  <akim@epita.fr>
 492
 493         For some reason, this was not applied.
 494
 495         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 507         * src/files.c (obstack_save): New function.
 508         (done): Rename as...
 509         (output_files): this.
 510         Use `obstack_save'.
 511         * src/main.c (main): Don't use `atexit' to register `done', since
 512         it no longer has to remove tmp files, just call `output_files'
 513         when there are no errors.

 560

 583
 584         * src/reader.c (copy_comment2): Expect the input stream to be on
 585         the `/' which is suspected to open a comment, instead of being
 586         called after `//' or `/*' was read.
 587         (copy_comment, copy_definition, parse_union_decl, copy_action)

 620         Reported by Piotr Gackiewicz, and fixed by Neil Booth.

 629         * src/reader.c (parse_expect_decl): Keep `count' within the size
 630         of `buffer'.
 631         From Neil Booth.
 632
 633 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 634
 635         * bison.s1 (yyparse): Assign the default value
 636         unconditionally, to avoid a GCC warning and make the parser a
 637         tad smaller.
 638
 639 2000-10-02  Akim Demaille  <akim@epita.fr>
 640

 645
 646         * src/derives.c, src/print.c, src/reduce.c: To ease the

 648
 649 2000-10-02  Akim Demaille  <akim@epita.fr>
 650
 651         The location tracking mechanism is precious for parse error
 652         messages.  Nevertheless, it is enabled only when `@n' is used in
 653         the grammar, which is a different issue (you can use it in error
 654         message, but not in the grammar per se).  Therefore, there should
 655         be another means to enable it.
 656
 657         * src/getargs.c (getargs): Support `--locations'.
 658         (usage): Report it.
 659         * src/getargs.h (locationsflag): Export it.
 660         * src/lex.c (percent_table): Support `%locations'.
 661         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 662         with `locationsflag'.
 663         * doc/bison.texinfo: Document `--locations' and `%locations'.
 664         Sort the options.
 665         * tests/calc.m4: Test it.
 666
 667         For regularity of the names, replace each
 668         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 669         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 670         In addition replace each `flag' with `_flag'.
 671
 672 2000-10-02  Akim Demaille  <akim@epita.fr>
 673
 674         Also test parse error messages, including with YYERROR_VERBOSE.
 675
 676         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 677         associative).
 678         Use it to check the computations.
 679         Use it to check `nonassoc' is honored.
 680         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 681         `--yyerror-verbose'.
 682         (_AT_CHECK_CALC): Adjust to this option.
 683         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 684
 685 2000-10-02  Akim Demaille  <akim@epita.fr>
 686
 687         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 688         the latter demonstrates a flaw in the handling of non debugging
 689         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 690         was used in order to simplify:
 691
 692         #if YYDEBUG
 693         if (yydebug)
 694         {
 695         ...
 696         }
 697         #endif
 698
 699         into
 700
 701         if (yydebug)
 702         {
 703         ...
 704         }
 705
 706         unfortunately this leads to a CPP conflict when
 707         `--name-prefix=foo' is used since it produces `#define yydebug
 708         foodebug'.
 709
 710         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 711         (YYDPRINTF): New macro.
 712         Spread its use.
 713         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 714         the bison options.
 715         Also test `--verbose', `--defines' and `--name-prefix'.
 716
 717 2000-10-02  Akim Demaille  <akim@epita.fr>
 718
 719         Improve the readability of the produced parsers.
 720
 721         * src/bison.s1: Formatting changes.
 722         Improve the comment related to the `$' mark.
 723         (yydefault): Don't fall through to `yyresume': `goto' there.
 724         * src/output.c (output_parser): When the `$' is met, skip the end
 725         of its line.
 726         New variable, `number_of_dollar_signs', to check there's exactly
 727         one `$' in the parser skeleton.
 728
 729 2000-10-02  Akim Demaille  <akim@epita.fr>
 730
 731         * lib/xstrdup.c: New file, from the fileutils.
 732         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 733         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 734         instead of strlen + xmalloc + strcpy.
 735         * src/symtab.c (copys): Remove, use xstrdup instead.
 736
 737 2000-10-02  Akim Demaille  <akim@epita.fr>
 738
 739         * src/gram.h (associativity): New enum type which replaces the
 740         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 741         `right_assoc', `left_assoc' and `non_assoc'.
 742         Adjust all dependencies.
 743         * src/reader.c: Formatting changes.
 744         (LTYPESTR): Don't define it, use it as a literal in
 745         `reader_output_yylsp'.
 746         * src/symtab.h (symbol_class): New enum type which replaces the
 747         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

 758         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 759         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 760         difficult and introduced a lot of core dump.  It turns out that
 761         Bison used an implementation of `xmalloc' based on `calloc', and
 762         at various places it does depend upon the initialization to 0.  I
 763         have not tried to isolate the pertinent places, and all the former
 764         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 765         someone should address this issue.
 766
 767         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 768         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

 865
 866 2000-10-02  Akim Demaille  <akim@epita.fr>
 867
 868         `user_toknums' is output as a `short[]' in `output.c', while it is
 869         defined as a `int[]' in `reader.c'.  For consistency with the
 870         other output tables, `user_toknums' is now defined as a table of
 871         shorts.
 872

 914         * src/system.h: Define PARAMS.
 915         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 916         purpose of config.h.  system.h must not try to fix wrong
 917         definitions in config.h.

1129         * src/reader.c (copy_string): New function, factored out from:
1130         (copy_action): Use it.
1131         (copy_guard): Likewise.
1132
1133 2000-03-17  Akim Demaille  <akim@epita.fr>
1134
1135         Change the handling of @s so that they behave exactly like $s.
1136         There is now a pseudo variable @$ (readble and writable), location
1137         of the lhs of the rule (by default ranging from the location of
1138         the first symbol of the rhs, to the location of the last symbol,
1139         or, if the rhs is empty, YYLLOC).
1140
1141         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1142         yyval.
1143         (yyparse): When providing a default semantic action, provide a
1144         default location action.
1145         (after the $): No longer change `*YYLSP', just stack YYLOC the
1146         same way you stack YYVAL.
1147         * src/reader.c (read_declarations): Use warns.
1148         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1149         (copy_action, case '@'): Likewise.
1150         Use a standard error message, to save useless work from
1151         translators.
1152
1153 2000-03-17  Akim Demaille  <akim@epita.fr>
1154

1172
1173         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1174         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1175         One `#if YYDEBUG' remains, since it uses variables which are
1176         defined only if `YYDEBUG != 0'.
1177

1204         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
1205         autoheader.

1210         the proper line number and file name.
1211         (DEFS): Propagate the location of bison library files and of the
1212         locale files.
1213         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1214         builddir.
1215         * acinclude.m4: Remove, replaced by the directory m4.
1216         * m4/Makefile.am (EXTRA_DIST): New variable.

1897         (literalchar, lex, parse_percent_token): Made tokenbuffer
1898         always contain the token.  This includes growing the token
1899         buffer while reading an integer.
1900         (parse_percent_token): Replaced if-else statement with percent_table.
1901         (parse_percent_token): Added % declarations as another
1902         way to specify the flags -n, -l, and -r.  Also added hooks for
1903         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
1904         major changes to files.c.
1905         (lex) Retain in the incoming stream a character following
1906         an incorrect '/'.
1907         (skip_white_space, lex):  Revised most error messages
1908         and changed fatal to warn to avoid aborting.
1909         (percent_table):  Added %thong declarations.

1915         and actfile file.  Handle noparserflag.  Both for -n switch.
1916
1917         * src/conflicts.c (resolve_sr_conflict):
