  12
  13         * src/vcg_default.h: Use NULL instead of 0 to initialize pointers.
  14         * src/vcg.c (output_node): Fix.
  15         * src/vcg.h: Cleanup.
  16         * src/print_graph.c: Add comments.
  17         (node_output_size): New global variable. Simplify the formatting of
  18         the VCG graph output.
  19         (print_actions): Unused code is now used. It notifies the final state
  20         and no action states in the VCG graph. It also give the reduce actions.
  21         The `shift and goto' edges are red and the `go to state' edges are
  22         blue.
  23         Get the current node name and node_obstack by argument.
  24         (node_obstack): New variable.
  25         (print_state): Manage node_obstack.
  26         (print_core): Use node_obstack given by argument.
  27         A node is not only computed here but in print_actions also.
  28         (print_graph): CPP out useless code instead of commenting it.

 219
 220 2001-02-21  Akim Demaille  <akim@epita.fr>
 221
 222         * src/reader.c (gensym): `gensym_count' is your own.
 223         Use a static buf to create the symbol name, as token_buffer is no
 224         longer a buffer.
 225

 227
 228         * src/conflicts.c (conflict_report): Be sure not to append to res
 229         between two calls, which could happen if both first sprintf were

 232 2001-02-08  Akim Demaille  <akim@epita.fr>
 233
 234         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
 235         New, from fileutils 4.0.37.
 236         * configure.in: Require Autoconf 2.49c.  I took some time before
 237         making this decision.  This is the only way out for portability
 238         issues in Bison, it would mean way too much duplicate effort to
 239         import in Bison features implemented in 2.49c since 2.13.
 240         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
 241

 250         the obstacks.
 251
 252         * src/lex.c (token_obstack): New.
 253         (init_lex): Initialize it.  No longer call...
 254         (grow_token_buffer): this.  Remove it.
 255         Adjust all the places which used it to use the obstack.
 256
 257 2001-01-19  Akim Demaille  <akim@epita.fr>
 258
 259         * src/lex.h: Rename all the tokens:
 260         s/\bENDFILE\b/tok_eof/g;
 261         s/\bIDENTIFIER\b/tok_identifier/g;
 262         etc.
 263         Let them be enums, not #define, to ease debugging.
 264         Adjust all the code.
 265
 266 2001-01-18  Akim Demaille  <akim@epita.fr>
 267
 268         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 269         * src/lex.c (maxtoken, grow_token_buffer): Static.
 270
 271 2001-01-18  Akim Demaille  <akim@epita.fr>
 272
 273         Since we now use obstacks, more % directives can be enabled.
 274
 275         * src/lex.c (percent_table): Also accept `%yacc',
 276         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 277         `%debug'.
 278         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 279         instead of returning a token.
 280         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 281         * src/reader.c (read_declarations): Adjust.
 282         * src/files.c (open_files): Don't call `compute_base_names', don't
 283         compute `attrsfile' since they depend upon data which might be
 284         *in* the input file now.
 285         (output_files): Do it here.
 286         * src/output.c (output_headers): Document the fact that this patch
 287         introduces a guaranteed SEGV for semantic parsers.
 288         * doc/bison.texinfo: Document them.

 299         * src/system.h (obstack_grow_string): Rename as...
 300         (obstack_sgrow): this.  Be ready to work with non literals.
 301         (obstack_fgrow4): New.
 302
 303 2000-12-20  Akim Demaille  <akim@epita.fr>
 304
 305         * src/files.c (open_files): Fix the computation of short_base_name
 306         in the case of `-o foo.tab.c'.
 307
 308 2000-12-20  Akim Demaille  <akim@epita.fr>
 309
 310         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 311         (copy_dollar): Now that everything uses obstacks, get rid of the
 312         FILE * parameters.
 313
 314 2000-12-20  Akim Demaille  <akim@epita.fr>
 315
 316         * src/files.c (open_files): Actually the `.output' file is based
 317         on the short_base_name, not base_name.
 318         * tests/suite.at (Checking output file names): Adjust.
 319
 320 2000-12-20  Akim Demaille  <akim@epita.fr>
 321
 322         * src/bison.s1: Remove, we now use directly...
 323         * src/bison.simple: this.
 324         * src/Makefile.am: Use pkgdata instead of data.
 325
 326 2000-12-20  Akim Demaille  <akim@epita.fr>
 327
 328         * src/files.c (guard_obstack): New.

 346         (stringappend): Be just like strcat but allocate.
 347         (base_names): Eve out from open_files.
 348         Try to simplify the rather hairy computation of base_name and
 349         short_base_name.
 350         (open_files): Use it.
 351         * tests/suite.at (Checking output file names): New test.
 352
 353 2000-12-19  Akim Demaille  <akim@epita.fr>

 365         there are.
 366         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
 367         Suggested by Hans Aberg.
 368
 369 2000-12-19  Akim Demaille  <akim@epita.fr>
 370
 371         Let the handling of the skeleton files be local to the procedures

 390
 391         * src/files.c (open_files): Yipee!  We no longer need all the code

 395
 396         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

 422
 423         * lib/obstack.h: Formatting changes.
 424         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 425         prevents type checking.
 426         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 427         cast the value to (void *): assigning a `foo *' to a `void *'
 428         variable is valid.

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

 491
 492         For some reason, this was not applied.
 493
 494         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

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

 630         From Neil Booth.
 631
 632 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 633
 634         * bison.s1 (yyparse): Assign the default value
 635         unconditionally, to avoid a GCC warning and make the parser a
 636         tad smaller.
 637
 638 2000-10-02  Akim Demaille  <akim@epita.fr>
 639

 647
 648 2000-10-02  Akim Demaille  <akim@epita.fr>
 649
 650         The location tracking mechanism is precious for parse error
 651         messages.  Nevertheless, it is enabled only when `@n' is used in
 652         the grammar, which is a different issue (you can use it in error
 653         message, but not in the grammar per se).  Therefore, there should
 654         be another means to enable it.
 655
 656         * src/getargs.c (getargs): Support `--locations'.
 657         (usage): Report it.
 658         * src/getargs.h (locationsflag): Export it.
 659         * src/lex.c (percent_table): Support `%locations'.
 660         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 661         with `locationsflag'.
 662         * doc/bison.texinfo: Document `--locations' and `%locations'.
 663         Sort the options.
 664         * tests/calc.m4: Test it.
 665
 666         For regularity of the names, replace each
 667         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 668         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 669         In addition replace each `flag' with `_flag'.
 670
 671 2000-10-02  Akim Demaille  <akim@epita.fr>
 672
 673         Also test parse error messages, including with YYERROR_VERBOSE.
 674
 675         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 676         associative).
 677         Use it to check the computations.
 678         Use it to check `nonassoc' is honored.
 679         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 680         `--yyerror-verbose'.
 681         (_AT_CHECK_CALC): Adjust to this option.
 682         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 683
 684 2000-10-02  Akim Demaille  <akim@epita.fr>
 685
 686         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 687         the latter demonstrates a flaw in the handling of non debugging
 688         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 689         was used in order to simplify:
 690
 691         #if YYDEBUG
 692         if (yydebug)
 693         {
 694         ...
 695         }
 696         #endif
 697
 698         into
 699
 700         if (yydebug)
 701         {
 702         ...
 703         }
 704
 705         unfortunately this leads to a CPP conflict when
 706         `--name-prefix=foo' is used since it produces `#define yydebug
 707         foodebug'.
 708
 709         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 710         (YYDPRINTF): New macro.
 711         Spread its use.
 712         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 713         the bison options.
 714         Also test `--verbose', `--defines' and `--name-prefix'.
 715
 716 2000-10-02  Akim Demaille  <akim@epita.fr>
 717
 718         Improve the readability of the produced parsers.
 719
 720         * src/bison.s1: Formatting changes.
 721         Improve the comment related to the `$' mark.
 722         (yydefault): Don't fall through to `yyresume': `goto' there.
 723         * src/output.c (output_parser): When the `$' is met, skip the end
 724         of its line.
 725         New variable, `number_of_dollar_signs', to check there's exactly
 726         one `$' in the parser skeleton.
 727
 728 2000-10-02  Akim Demaille  <akim@epita.fr>
 729
 730         * lib/xstrdup.c: New file, from the fileutils.
 731         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 732         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 733         instead of strlen + xmalloc + strcpy.
 734         * src/symtab.c (copys): Remove, use xstrdup instead.
 735
 736 2000-10-02  Akim Demaille  <akim@epita.fr>
 737
 738         * src/gram.h (associativity): New enum type which replaces the
 739         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 740         `right_assoc', `left_assoc' and `non_assoc'.
 741         Adjust all dependencies.
 742         * src/reader.c: Formatting changes.
 743         (LTYPESTR): Don't define it, use it as a literal in
 744         `reader_output_yylsp'.
 745         * src/symtab.h (symbol_class): New enum type which replaces the
 746         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 747         `sunknown', `stoken and `snterm'.

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

 863         output_short_table.
 864
 865 2000-10-02  Akim Demaille  <akim@epita.fr>
 866
 867         `user_toknums' is output as a `short[]' in `output.c', while it is
 868         defined as a `int[]' in `reader.c'.  For consistency with the
 869         other output tables, `user_toknums' is now defined as a table of
 870         shorts.
 871

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

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

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

1209         the proper line number and file name.
1210         (DEFS): Propagate the location of bison library files and of the
1211         locale files.
1212         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1213         builddir.
1214         * acinclude.m4: Remove, replaced by the directory m4.
1215         * m4/Makefile.am (EXTRA_DIST): New variable.

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