   2
   3         * src/reader.c (reader): Remove calls to 'output_headers' and

  12         declarations.
  13         (copy_string2): Put the body of copy_string into this new function.
  14         Add a parameter to let the caller choose whether he wants to copy the
  15         string delimiters or not.
  16         (copy_string): Be a simple call to copy_string2 with the last argument
  17         bound to true.

  27         (output_parser): Fix bug on '%%line' directives.
  28
  29         * src/output.c (output_headers): Remove. The C code printed by this
  30         function should now be in the skeletons.
  31         (output_trailers): Remove.
  32         (output): Disable call to 'reader_output_yylsp'.
  33         (output_rule_data): Do not output tables to the table obstack.

  36         Improve the use of macro and output obstacks.
  37         (output_defines): Remove.
  38
  39         * src/output.c (output_token_translations): Associate 'translate'
  40         table with a macro. No output to the table obstack.
  41         (output_gram): Same for 'rhs' and 'prhs'.

  53
  54         * src/output.c (output_parser): Replace most of the skeleton copy code
  55         with something new. Skeletons are now processed character by character
  56         rather than line by line, and Bison looks for '%%' macros. This is the
  57         first step in making Bison's output process (a lot) more flexible.

 381 2001-03-16  Akim Demaille  <akim@epita.fr>
 382
 383         * src/getargs.c (longopts): Clean up.
 384
 385 2001-02-21  Akim Demaille  <akim@epita.fr>
 386
 387         * src/reader.c (gensym): `gensym_count' is your own.
 388         Use a static buf to create the symbol name, as token_buffer is no
 389         longer a buffer.
 390
 391 2001-02-08  Akim Demaille  <akim@epita.fr>
 392
 393         * src/conflicts.c (conflict_report): Be sure not to append to res
 394         between two calls, which could happen if both first sprintf were
 395         skipped, but not the first cp += strlen.
 396
 397 2001-02-08  Akim Demaille  <akim@epita.fr>
 398
 399         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
 400         New, from fileutils 4.0.37.
 401         * configure.in: Require Autoconf 2.49c.  I took some time before
 402         making this decision.  This is the only way out for portability
 403         issues in Bison, it would mean way too much duplicate effort to
 404         import in Bison features implemented in 2.49c since 2.13.
 405         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
 406
 407 2001-02-02  Akim Demaille  <akim@epita.fr>
 408
 409         * lib/malloc.c, lib/realloc.c: New, from the fileutils 4.0.37.

 411
 412 2001-01-19  Akim Demaille  <akim@epita.fr>
 413
 414         Get rid of the ad hoc handling of token_buffer in the scanner: use
 415         the obstacks.
 416
 417         * src/lex.c (token_obstack): New.
 418         (init_lex): Initialize it.  No longer call...
 419         (grow_token_buffer): this.  Remove it.
 420         Adjust all the places which used it to use the obstack.
 421
 422 2001-01-19  Akim Demaille  <akim@epita.fr>
 423
 424         * src/lex.h: Rename all the tokens:
 425         s/\bENDFILE\b/tok_eof/g;
 426         s/\bIDENTIFIER\b/tok_identifier/g;
 427         etc.
 428         Let them be enums, not #define, to ease debugging.
 429         Adjust all the code.
 430
 431 2001-01-18  Akim Demaille  <akim@epita.fr>
 432
 433         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 434         * src/lex.c (maxtoken, grow_token_buffer): Static.
 435
 436 2001-01-18  Akim Demaille  <akim@epita.fr>
 437
 438         Since we now use obstacks, more % directives can be enabled.
 439
 440         * src/lex.c (percent_table): Also accept `%yacc',
 441         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 442         `%debug'.
 443         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 444         instead of returning a token.
 445         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 446         * src/reader.c (read_declarations): Adjust.
 447         * src/files.c (open_files): Don't call `compute_base_names', don't
 448         compute `attrsfile' since they depend upon data which might be
 449         *in* the input file now.
 450         (output_files): Do it here.
 451         * src/output.c (output_headers): Document the fact that this patch
 452         introduces a guaranteed SEGV for semantic parsers.
 453         * doc/bison.texinfo: Document them.
 454         * tests/suite.at: Exercise these %options.
 455
 456 2000-12-20  Akim Demaille  <akim@epita.fr>
 457
 458         Also handle the output file (--verbose) with obstacks.

 460         * files.c (foutput): Remove.

 462         Adjust all dependencies.

 464         * src/system.h (obstack_grow_string): Rename as...
 465         (obstack_sgrow): this.  Be ready to work with non literals.
 466         (obstack_fgrow4): New.
 467
 468 2000-12-20  Akim Demaille  <akim@epita.fr>
 469
 470         * src/files.c (open_files): Fix the computation of short_base_name
 471         in the case of `-o foo.tab.c'.
 472
 473 2000-12-20  Akim Demaille  <akim@epita.fr>
 474
 475         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 476         (copy_dollar): Now that everything uses obstacks, get rid of the
 477         FILE * parameters.
 478
 479 2000-12-20  Akim Demaille  <akim@epita.fr>
 480
 481         * src/files.c (open_files): Actually the `.output' file is based
 482         on the short_base_name, not base_name.
 483         * tests/suite.at (Checking output file names): Adjust.
 484
 485 2000-12-20  Akim Demaille  <akim@epita.fr>
 486
 487         * src/bison.s1: Remove, we now use directly...
 488         * src/bison.simple: this.
 489         * src/Makefile.am: Use pkgdata instead of data.
 490
 491 2000-12-20  Akim Demaille  <akim@epita.fr>
 492
 493         * src/files.c (guard_obstack): New.

 500
 501         * src/files.c (outfile, defsfile, actfile): Removed as global
 502         vars.
 503         (open_files): Don't compute them.
 504         (output_files): Adjust.

 509
 510         * src/files.c (strsuffix): New.
 511         (stringappend): Be just like strcat but allocate.
 512         (base_names): Eve out from open_files.
 513         Try to simplify the rather hairy computation of base_name and
 514         short_base_name.
 515         (open_files): Use it.
 516         * tests/suite.at (Checking output file names): New test.
 517
 518 2000-12-19  Akim Demaille  <akim@epita.fr>
 519

 522         * src/output.c (output_parser): Recognize `%% actions' instead of
 523         `$'.
 524         * src/bison.s1: s/$/%% actions/.
 525         * src/bison.hairy: Likewise.
 526
 527 2000-12-19  Akim Demaille  <akim@epita.fr>
 528
 529         * src/output.c (output_parser): Compute the `#line' lines when
 530         there are.
 531         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
 532         Suggested by Hans Aberg.
 533
 534 2000-12-19  Akim Demaille  <akim@epita.fr>
 535
 536         Let the handling of the skeleton files be local to the procedures
 537         that use it.
 538
 539         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
 540         longer static.
 541         (fparser, open_extra_files): Remove.
 542         (open_files, output_files): Don't take care of fparser.

 549 2000-12-19  Akim Demaille  <akim@epita.fr>
 550
 551         * src/file.h (BISON_SIMPLE, BISON_HAIRY): Move from here...

 553
 554 2000-12-19  Akim Demaille  <akim@epita.fr>
 555
 556         * src/files.c (open_files): Yipee!  We no longer need all the code
 557         looking for `/tmp' since we have no tmp file.
 558
 559 2000-12-19  Akim Demaille  <akim@epita.fr>
 560
 561         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 562         New macros.
 563         * src/files.c (open_files): Less dependency on MSDOS etc.

 576         (copy_guard): Quote the file names.
 577         Reported by Laurent Mascherpa.
 578
 579 2000-12-12  Akim Demaille  <akim@epita.fr>

 587
 588         * lib/obstack.h: Formatting changes.
 589         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 590         prevents type checking.
 591         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 592         cast the value to (void *): assigning a `foo *' to a `void *'
 593         variable is valid.
 594         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 595         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
 596         append characters.
 597

 611
 612         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
 613         macros.

 630
 631 2000-11-07  Akim Demaille  <akim@epita.fr>
 632
 633         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
 634         Merge in a single CPP if/else.
 635
 636 2000-11-07  Akim Demaille  <akim@epita.fr>
 637

 643         `address' for consistency.  Qualify it `const'.
 644         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 645         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
 646         `const' their input argument (`data' or `address').
 647         Adjust the corresponding macros to include `const' in casts.

 650
 651         * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

 656
 657         For some reason, this was not applied.
 658
 659         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 674         Use `obstack_save'.
 675         * src/main.c (main): Don't use `atexit' to register `done', since
 676         it no longer has to remove tmp files, just call `output_files'
 677         when there are no errors.
 678

 781
 782         When a literal string is used to define two different tokens,
 783         `bison -v' segfaults.
 784         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 785
 786         * tests/regression.m4: New file.
 787         Include the core of the sample provided by Piotr Gackiewicz.
 788         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
 789         properly.

 795         From Neil Booth.
 796
 797 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 798
 799         * bison.s1 (yyparse): Assign the default value
 800         unconditionally, to avoid a GCC warning and make the parser a
 801         tad smaller.
 802
 803 2000-10-02  Akim Demaille  <akim@epita.fr>
 804
 805         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
 806         options.

 809
 810         * src/derives.c, src/print.c, src/reduce.c: To ease the

 812
 813 2000-10-02  Akim Demaille  <akim@epita.fr>
 814
 815         The location tracking mechanism is precious for parse error
 816         messages.  Nevertheless, it is enabled only when `@n' is used in
 817         the grammar, which is a different issue (you can use it in error
 818         message, but not in the grammar per se).  Therefore, there should
 819         be another means to enable it.
 820
 821         * src/getargs.c (getargs): Support `--locations'.
 822         (usage): Report it.
 823         * src/getargs.h (locationsflag): Export it.
 824         * src/lex.c (percent_table): Support `%locations'.
 825         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 826         with `locationsflag'.
 827         * doc/bison.texinfo: Document `--locations' and `%locations'.
 828         Sort the options.
 829         * tests/calc.m4: Test it.
 830
 831         For regularity of the names, replace each
 832         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 833         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 834         In addition replace each `flag' with `_flag'.
 835
 836 2000-10-02  Akim Demaille  <akim@epita.fr>
 837
 838         Also test parse error messages, including with YYERROR_VERBOSE.
 839
 840         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 841         associative).
 842         Use it to check the computations.
 843         Use it to check `nonassoc' is honored.
 844         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 845         `--yyerror-verbose'.
 846         (_AT_CHECK_CALC): Adjust to this option.
 847         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 848
 849 2000-10-02  Akim Demaille  <akim@epita.fr>
 850
 851         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 852         the latter demonstrates a flaw in the handling of non debugging
 853         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 854         was used in order to simplify:
 855
 856         #if YYDEBUG
 857         if (yydebug)
 858         {
 859         ...
 860         }
 861         #endif
 862
 863         into
 864
 865         if (yydebug)
 866         {
 867         ...
 868         }
 869
 870         unfortunately this leads to a CPP conflict when
 871         `--name-prefix=foo' is used since it produces `#define yydebug
 872         foodebug'.
 873
 874         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 875         (YYDPRINTF): New macro.
 876         Spread its use.
 877         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 878         the bison options.
 879         Also test `--verbose', `--defines' and `--name-prefix'.
 880
 881 2000-10-02  Akim Demaille  <akim@epita.fr>
 882
 883         Improve the readability of the produced parsers.
 884
 885         * src/bison.s1: Formatting changes.
 886         Improve the comment related to the `$' mark.
 887         (yydefault): Don't fall through to `yyresume': `goto' there.
 888         * src/output.c (output_parser): When the `$' is met, skip the end
 889         of its line.
 890         New variable, `number_of_dollar_signs', to check there's exactly
 891         one `$' in the parser skeleton.
 892
 893 2000-10-02  Akim Demaille  <akim@epita.fr>
 894
 895         * lib/xstrdup.c: New file, from the fileutils.
 896         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 897         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 898         instead of strlen + xmalloc + strcpy.
 899         * src/symtab.c (copys): Remove, use xstrdup instead.
 900
 901 2000-10-02  Akim Demaille  <akim@epita.fr>
 902
 903         * src/gram.h (associativity): New enum type which replaces the
 904         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 905         `right_assoc', `left_assoc' and `non_assoc'.
 906         Adjust all dependencies.
 907         * src/reader.c: Formatting changes.
 908         (LTYPESTR): Don't define it, use it as a literal in
 909         `reader_output_yylsp'.
 910         * src/symtab.h (symbol_class): New enum type which replaces the
 911         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 912         `sunknown', `stoken and `snterm'.
 913
 914 2000-10-02  Akim Demaille  <akim@epita.fr>
 915
 916         * src/getargs.c (fixed_outfiles): Rename as...
 917         (yaccflag): for consistency and accuracy.
 918         Adjust dependencies.
 919
 920 2000-10-02  Akim Demaille  <akim@epita.fr>
 921
 922         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 923         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 924         difficult and introduced a lot of core dump.  It turns out that
 925         Bison used an implementation of `xmalloc' based on `calloc', and
 926         at various places it does depend upon the initialization to 0.  I
 927         have not tried to isolate the pertinent places, and all the former
 928         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 929         someone should address this issue.
 930
 931         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 932         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 933         files.
 934         Adjust dependencies.
 935         * src/warshall.h: New file.
 936         Propagate.

 938 2000-10-02  Akim Demaille  <akim@epita.fr>

 943
 944 2000-10-02  Akim Demaille  <akim@epita.fr>
 945
 946         * src/state.h (nstates, final_state, first_state, first_shift)
 947         (first_reduction): Move their exportation from here...
 948         * src/LR0.h: to here.
 949         Adjust dependencies.
 950         * src/getargs.c (statisticsflag): New variable.

1001
1002 2000-10-02  Akim Demaille  <akim@epita.fr>
1003
1004         * src/reader.h: New file.
1005         Propagate its use instead of tedious list of `extern' and

1023
1024 2000-10-02  Akim Demaille  <akim@epita.fr>
1025
1026         * src/output.c (token_actions): Introduce a temporary array,
1027         YYDEFACT, that makes it possible for this function to use
1028         output_short_table.
1029
1030 2000-10-02  Akim Demaille  <akim@epita.fr>
1031
1032         `user_toknums' is output as a `short[]' in `output.c', while it is
1033         defined as a `int[]' in `reader.c'.  For consistency with the
1034         other output tables, `user_toknums' is now defined as a table of
1035         shorts.
1036
1037         * src/reader.c (user_toknums): Be a short table instead of an int
1038         table.

1048
1049         * src/output.c (output): Topological sort of the functions, in
1050         order to get rid of the `static' prototypes.
1051         No longer use `register'.
1052         * src/output.h: New file.
1053         Propagate its inclusion in files explicitly prototyping functions
1054         from output.c.

1066         (new_closure, free_closure): these.  Adjust dependencies.

1076         inclusion.
1077         Don't define PARAMS.
1078         * src/system.h: Define PARAMS.
1079         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
1080         purpose of config.h.  system.h must not try to fix wrong
1081         definitions in config.h.

1106         Let all `extern' declarations about getargs.c be replaced with

1244
1245 2000-03-17  Akim Demaille  <akim@epita.fr>
1246
1247         On syntax errors, report the token on which we choked.

1269         copy_comment.  Removed now unused `match', `ended',
1270         `cplus_comment'.
1271         (copy_comment, copy_string): Moved, to be visible from
1272         copy_definition.
1273

1275

1298
1299         Change the handling of @s so that they behave exactly like $s.
1300         There is now a pseudo variable @$ (readble and writable), location
1301         of the lhs of the rule (by default ranging from the location of
1302         the first symbol of the rhs, to the location of the last symbol,
1303         or, if the rhs is empty, YYLLOC).
1304
1305         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1306         yyval.
1307         (yyparse): When providing a default semantic action, provide a
1308         default location action.
1309         (after the $): No longer change `*YYLSP', just stack YYLOC the
1310         same way you stack YYVAL.
1311         * src/reader.c (read_declarations): Use warns.
1312         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1313         (copy_action, case '@'): Likewise.
1314         Use a standard error message, to save useless work from
1315         translators.
1316
1317 2000-03-17  Akim Demaille  <akim@epita.fr>
1318

1336
1337         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1338         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1339         One `#if YYDEBUG' remains, since it uses variables which are
1340         defined only if `YYDEBUG != 0'.
1341
1342 2000-03-16  Akim Demaille  <akim@epita.fr>

1368         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

1374         the proper line number and file name.
1375         (DEFS): Propagate the location of bison library files and of the
1376         locale files.
1377         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1378         builddir.
1379         * acinclude.m4: Remove, replaced by the directory m4.
1380         * m4/Makefile.am (EXTRA_DIST): New variable.
1381         * m4/gettext.m4: New file, from the fileutils.
