 281
 282         * src/reader.c (gensym): `gensym_count' is your own.

 296         * configure.in: Require Autoconf 2.49c.  I took some time before
 297         making this decision.  This is the only way out for portability
 298         issues in Bison, it would mean way too much duplicate effort to
 299         import in Bison features implemented in 2.49c since 2.13.
 300         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

 311
 312         * src/lex.c (token_obstack): New.
 313         (init_lex): Initialize it.  No longer call...

 321         s/\bIDENTIFIER\b/tok_identifier/g;
 322         etc.
 323         Let them be enums, not #define, to ease debugging.
 324         Adjust all the code.
 325
 326 2001-01-18  Akim Demaille  <akim@epita.fr>
 327

 330
 331 2001-01-18  Akim Demaille  <akim@epita.fr>
 332
 333         Since we now use obstacks, more % directives can be enabled.
 334
 335         * src/lex.c (percent_table): Also accept `%yacc',
 336         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 337         `%debug'.
 338         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 339         instead of returning a token.
 340         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 341         * src/reader.c (read_declarations): Adjust.
 342         * src/files.c (open_files): Don't call `compute_base_names', don't
 343         compute `attrsfile' since they depend upon data which might be
 344         *in* the input file now.
 345         (output_files): Do it here.
 346         * src/output.c (output_headers): Document the fact that this patch
 347         introduces a guaranteed SEGV for semantic parsers.

 359         * src/system.h (obstack_grow_string): Rename as...
 360         (obstack_sgrow): this.  Be ready to work with non literals.
 361         (obstack_fgrow4): New.
 362
 363 2000-12-20  Akim Demaille  <akim@epita.fr>

 370         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 371         (copy_dollar): Now that everything uses obstacks, get rid of the
 372         FILE * parameters.
 373
 374 2000-12-20  Akim Demaille  <akim@epita.fr>
 375
 376         * src/files.c (open_files): Actually the `.output' file is based

 411         * tests/suite.at (Checking output file names): New test.

 428
 429 2000-12-19  Akim Demaille  <akim@epita.fr>
 430
 431         Let the handling of the skeleton files be local to the procedures
 432         that use it.

 444 2000-12-19  Akim Demaille  <akim@epita.fr>
 445
 446         * src/file.h (BISON_SIMPLE, BISON_HAIRY): Move from here...

 448
 449 2000-12-19  Akim Demaille  <akim@epita.fr>
 450
 451         * src/files.c (open_files): Yipee!  We no longer need all the code
 452         looking for `/tmp' since we have no tmp file.
 453
 454 2000-12-19  Akim Demaille  <akim@epita.fr>
 455
 456         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 457         New macros.

 461
 462         * src/bison.s1 (YYLLOC_DEFAULT): New macro.

 482
 483         * lib/obstack.h: Formatting changes.
 484         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 485         prevents type checking.
 486         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 487         cast the value to (void *): assigning a `foo *' to a `void *'
 488         variable is valid.
 489         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 490         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
 491         append characters.
 492

 494
 495         * tests/Makefile.am (suite.m4, regression.m4, calc.m4): Rename

 525
 526 2000-11-07  Akim Demaille  <akim@epita.fr>
 527
 528         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

 537         (obstack_copy, obstack_copy0): Rename the second argument as
 538         `address' for consistency.  Qualify it `const'.
 539         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 540         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

 549
 550 2000-11-03  Akim Demaille  <akim@epita.fr>
 551
 552         For some reason, this was not applied.
 553
 554         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 567         (done): Rename as...
 568         (output_files): this.
 569         Use `obstack_save'.
 570         * src/main.c (main): Don't use `atexit' to register `done', since
 571         it no longer has to remove tmp files, just call `output_files'
 572         when there are no errors.
 573
 574 2000-11-02  Akim Demaille  <akim@epita.fr>

 599         * src/files.c (fattrs): Remove.
 600         (attrs_obstack): New.
 601         Adjust all dependencies.

 603
 604 2000-11-01  Akim Demaille  <akim@epita.fr>
 605
 606         Introduce obstacks.
 607         Change each use of `faction' into a use of `action_obstack'.

 618 2000-10-16  Akim Demaille  <akim@epita.fr>
 619

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

 674
 675 2000-10-04  Akim Demaille  <akim@epita.fr>
 676
 677         When a literal string is used to define two different tokens,
 678         `bison -v' segfaults.
 679         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 680
 681         * tests/regression.m4: New file.

 688         * src/reader.c (parse_expect_decl): Keep `count' within the size
 689         of `buffer'.
 690         From Neil Booth.
 691
 692 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 693
 694         * bison.s1 (yyparse): Assign the default value
 695         unconditionally, to avoid a GCC warning and make the parser a
 696         tad smaller.
 697
 698 2000-10-02  Akim Demaille  <akim@epita.fr>
 699

 703 2000-10-02  Akim Demaille  <akim@epita.fr>
 704
 705         * src/derives.c, src/print.c, src/reduce.c: To ease the
 706         translation, move some `\n' out of the translated strings.
 707
 708 2000-10-02  Akim Demaille  <akim@epita.fr>
 709
 710         The location tracking mechanism is precious for parse error
 711         messages.  Nevertheless, it is enabled only when `@n' is used in
 712         the grammar, which is a different issue (you can use it in error
 713         message, but not in the grammar per se).  Therefore, there should
 714         be another means to enable it.
 715
 716         * src/getargs.c (getargs): Support `--locations'.
 717         (usage): Report it.
 718         * src/getargs.h (locationsflag): Export it.
 719         * src/lex.c (percent_table): Support `%locations'.
 720         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 721         with `locationsflag'.
 722         * doc/bison.texinfo: Document `--locations' and `%locations'.
 723         Sort the options.
 724         * tests/calc.m4: Test it.
 725
 726         For regularity of the names, replace each
 727         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 728         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 729         In addition replace each `flag' with `_flag'.
 730
 731 2000-10-02  Akim Demaille  <akim@epita.fr>
 732
 733         Also test parse error messages, including with YYERROR_VERBOSE.
 734
 735         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 736         associative).
 737         Use it to check the computations.
 738         Use it to check `nonassoc' is honored.
 739         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 740         `--yyerror-verbose'.
 741         (_AT_CHECK_CALC): Adjust to this option.
 742         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 743
 744 2000-10-02  Akim Demaille  <akim@epita.fr>
 745
 746         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 747         the latter demonstrates a flaw in the handling of non debugging
 748         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 749         was used in order to simplify:
 750
 751         #if YYDEBUG
 752         if (yydebug)
 753         {

 760         if (yydebug)
 761         {
 762         ...
 763         }
 764
 765         unfortunately this leads to a CPP conflict when
 766         `--name-prefix=foo' is used since it produces `#define yydebug
 767         foodebug'.
 768
 769         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 770         (YYDPRINTF): New macro.
 771         Spread its use.
 772         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 773         the bison options.

 782         (yydefault): Don't fall through to `yyresume': `goto' there.
 783         * src/output.c (output_parser): When the `$' is met, skip the end
 784         of its line.
 785         New variable, `number_of_dollar_signs', to check there's exactly
 786         one `$' in the parser skeleton.
 787
 788 2000-10-02  Akim Demaille  <akim@epita.fr>
 789

 792         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 793         instead of strlen + xmalloc + strcpy.

 796 2000-10-02  Akim Demaille  <akim@epita.fr>
 797
 798         * src/gram.h (associativity): New enum type which replaces the
 799         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 800         `right_assoc', `left_assoc' and `non_assoc'.
 801         Adjust all dependencies.
 802         * src/reader.c: Formatting changes.
 803         (LTYPESTR): Don't define it, use it as a literal in
 804         `reader_output_yylsp'.
 805         * src/symtab.h (symbol_class): New enum type which replaces the
 806         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 807         `sunknown', `stoken and `snterm'.
 808

 815 2000-10-02  Akim Demaille  <akim@epita.fr>
 816
 817         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 818         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 819         difficult and introduced a lot of core dump.  It turns out that
 820         Bison used an implementation of `xmalloc' based on `calloc', and
 821         at various places it does depend upon the initialization to 0.  I
 822         have not tried to isolate the pertinent places, and all the former
 823         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 824         someone should address this issue.
 825
 826         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 827         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 828         files.

 839 2000-10-02  Akim Demaille  <akim@epita.fr>

 900         Propagate its use instead of tedious list of `extern' and
 901         prototypes.

 922         YYDEFACT, that makes it possible for this function to use
 923         output_short_table.
 924
 925 2000-10-02  Akim Demaille  <akim@epita.fr>
 926
 927         `user_toknums' is output as a `short[]' in `output.c', while it is
 928         defined as a `int[]' in `reader.c'.  For consistency with the
 929         other output tables, `user_toknums' is now defined as a table of
 930         shorts.
 931
 932         * src/reader.c (user_toknums): Be a short table instead of an int
 933         table.

 943
 944         * src/output.c (output): Topological sort of the functions, in
 945         order to get rid of the `static' prototypes.
 946         No longer use `register'.
 947         * src/output.h: New file.
 948         Propagate its inclusion in files explicitly prototyping functions
 949         from output.c.

 971         inclusion.
 972         Don't define PARAMS.
 973         * src/system.h: Define PARAMS.
 974         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 975         purpose of config.h.  system.h must not try to fix wrong
 976         definitions in config.h.

1138         the file name, not the whole `#line LINE FILE'.
1139
1140 2000-03-17  Akim Demaille  <akim@epita.fr>
1141
1142         On syntax errors, report the token on which we choked.

1164         copy_comment.  Removed now unused `match', `ended',
1165         `cplus_comment'.
1166         (copy_comment, copy_string): Moved, to be visible from
1167         copy_definition.

1193
1194         Change the handling of @s so that they behave exactly like $s.
1195         There is now a pseudo variable @$ (readble and writable), location
1196         of the lhs of the rule (by default ranging from the location of
1197         the first symbol of the rhs, to the location of the last symbol,
1198         or, if the rhs is empty, YYLLOC).
1199
1200         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1201         yyval.
1202         (yyparse): When providing a default semantic action, provide a
1203         default location action.
1204         (after the $): No longer change `*YYLSP', just stack YYLOC the
1205         same way you stack YYVAL.
1206         * src/reader.c (read_declarations): Use warns.
1207         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1208         (copy_action, case '@'): Likewise.
1209         Use a standard error message, to save useless work from
1210         translators.
1211
1212 2000-03-17  Akim Demaille  <akim@epita.fr>
1213
1214         * src/bison.s1: Formatting and cosmetics changes.

1231
1232         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1233         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1234         One `#if YYDEBUG' remains, since it uses variables which are
1235         defined only if `YYDEBUG != 0'.
1236
1237 2000-03-16  Akim Demaille  <akim@epita.fr>

1263         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

1271         locale files.
1272         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1273         builddir.
1274         * acinclude.m4: Remove, replaced by the directory m4.
1275         * m4/Makefile.am (EXTRA_DIST): New variable.
1276         * m4/gettext.m4: New file, from the fileutils.

1908         (readgram): Use `#if 0' around code that accepted %command
1909         inside grammar rules:  The documentation doesn't allow it,
1910         and it will fail since the %command processors scan for the next %.
1911         (parse_token_decl):  Extended the %token
1912         declaration to allow a multi-character symbol as an alias.

1921         (get_type_name, copy_guard, copy_action, readgram)
1922         (get_type, packsymbols):  Revised most error messages.
1923         Changed `fatal' to `warnxxx' to avoid aborting for error.
1924         Revised and use multiple warnxxx functions to avoid using VARARGS1.
1925         (read_declarations): Improve the error message for
1926         an invalid character.  Do not abort.
1927         (read_declarations, copy_guard, copy_action): Use
1928         printable_version to avoid unprintable characters in printed output.
1929         (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
1930         (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
1931         Allow the type of a non-terminal can be given
1932         more than once, as long as all specifications give the same type.
1933

1940         * src/main.c (main):
1941          If reader sees an error, don't process the grammar.
1942         (fatals): Updated to not use VARARGS1.
1943         (printable_version, int_to_string, warn, warni, warns, warnss)
1944         (warnsss): New error reporting functions.  Avoid abort for error.
1945
1946         * src/lex.h:
1947         Added THONG and NOOP for alias processing.
1948         Added SETOPT for the new code that allows setting options with %flags.

1956         (literalchar, lex, parse_percent_token): Made tokenbuffer
1957         always contain the token.  This includes growing the token
1958         buffer while reading an integer.

1960         (parse_percent_token): Added % declarations as another
1961         way to specify the flags -n, -l, and -r.  Also added hooks for
1962         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
1963         major changes to files.c.
1964         (lex) Retain in the incoming stream a character following
1965         an incorrect '/'.
1966         (skip_white_space, lex):  Revised most error messages
1967         and changed fatal to warn to avoid aborting.
1968         (percent_table):  Added %thong declarations.
