ChangeLog

   1 2000-12-12  Akim Demaille  <akim@epita.fr>
   2
   3         * src/output.c (output_headers, output_program, output): Be sure
   4         to escape special characters when outputting filenames.
   5         (ACTSTR_PROLOGUE, ACTSTR_EPILOGUE): Remove.
   6         (output_headers): Don't depend on them, Use ACTSTR.
   7
   8 2000-11-17  Akim Demaille  <akim@epita.fr>
   9
  10         * lib/obstack.h: Formatting changes.
  11         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
  12         prevents type checking.
  13         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
  14         cast the value to (void *): assigning a `foo *' to a `void *'
  15         variable is valid.
  16         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
  17         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
  18         append characters.

  26
  27 2000-11-17  Akim Demaille  <akim@epita.fr>

  33
  34         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
  35         macros.

  50         defining.
  51         * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
  52
  53 2000-11-07  Akim Demaille  <akim@epita.fr>
  54
  55         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
  56         Merge in a single CPP if/else.
  57
  58 2000-11-07  Akim Demaille  <akim@epita.fr>
  59
  60         * src/output.c (output): Remove useless variables.
  61         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
  62         argument `data' for consistency with the prototypes.
  63         Qualify it `const'.
  64         (obstack_copy, obstack_copy0): Rename the second argument as
  65         `address' for consistency.  Qualify it `const'.
  66         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
  67         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
  68         `const' their input argument (`data' or `address').
  69         Adjust the corresponding macros to include `const' in casts.

  75         Adjust dependencies.
  76
  77 2000-11-03  Akim Demaille  <akim@epita.fr>
  78
  79         For some reason, this was not applied.
  80
  81         * src/files.c [VMS]: No longer include `ssdef.h', no longer define
  82         `unlink': it's no longer used.

  85
  86         * src/files.c (skeleton_find): New function, eved out of...

  93         * src/files.c (obstack_save): New function.
  94         (done): Rename as...
  95         (output_files): this.
  96         Use `obstack_save'.
  97         * src/main.c (main): Don't use `atexit' to register `done', since
  98         it no longer has to remove tmp files, just call `output_files'
  99         when there are no errors.
 100
 101 2000-11-02  Akim Demaille  <akim@epita.fr>
 102
 103         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 124
 125         * src/reader.c (copy_at): Typo: s/yylloc/yyloc/.
 126         * src/files.c (fattrs): Remove.
 127         (attrs_obstack): New.
 128         Adjust all dependencies.

 144
 145 2000-10-16  Akim Demaille  <akim@epita.fr>
 146

 169
 170         * src/reader.c (copy_comment2): Expect the input stream to be on
 171         the `/' which is suspected to open a comment, instead of being
 172         called after `//' or `/*' was read.
 173         (copy_comment, copy_definition, parse_union_decl, copy_action)
 174         (copy_guard): Adjust.

 199

 201
 202 2000-10-04  Akim Demaille  <akim@epita.fr>
 203
 204         When a literal string is used to define two different tokens,
 205         `bison -v' segfaults.
 206         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 207
 208         * tests/regression.m4: New file.
 209         Include the core of the sample provided by Piotr Gackiewicz.
 210         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
 211         properly.
 212
 213 2000-10-04  Akim Demaille  <akim@epita.fr>
 214
 215         * src/reader.c (parse_expect_decl): Keep `count' within the size
 216         of `buffer'.
 217         From Neil Booth.
 218
 219 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 220
 221         * bison.s1 (yyparse): Assign the default value
 222         unconditionally, to avoid a GCC warning and make the parser a
 223         tad smaller.
 224
 225 2000-10-02  Akim Demaille  <akim@epita.fr>
 226
 227         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
 228         options.
 229
 230 2000-10-02  Akim Demaille  <akim@epita.fr>
 231
 232         * src/derives.c, src/print.c, src/reduce.c: To ease the
 233         translation, move some `\n' out of the translated strings.
 234
 235 2000-10-02  Akim Demaille  <akim@epita.fr>
 236
 237         The location tracking mechanism is precious for parse error
 238         messages.  Nevertheless, it is enabled only when `@n' is used in
 239         the grammar, which is a different issue (you can use it in error
 240         message, but not in the grammar per se).  Therefore, there should
 241         be another means to enable it.
 242
 243         * src/getargs.c (getargs): Support `--locations'.
 244         (usage): Report it.
 245         * src/getargs.h (locationsflag): Export it.
 246         * src/lex.c (percent_table): Support `%locations'.
 247         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 248         with `locationsflag'.
 249         * doc/bison.texinfo: Document `--locations' and `%locations'.
 250         Sort the options.
 251         * tests/calc.m4: Test it.
 252
 253         For regularity of the names, replace each
 254         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 255         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 256         In addition replace each `flag' with `_flag'.
 257
 258 2000-10-02  Akim Demaille  <akim@epita.fr>
 259
 260         Also test parse error messages, including with YYERROR_VERBOSE.
 261
 262         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 263         associative).
 264         Use it to check the computations.
 265         Use it to check `nonassoc' is honored.
 266         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 267         `--yyerror-verbose'.
 268         (_AT_CHECK_CALC): Adjust to this option.
 269         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 270
 271 2000-10-02  Akim Demaille  <akim@epita.fr>
 272
 273         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 274         the latter demonstrates a flaw in the handling of non debugging
 275         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 276         was used in order to simplify:
 277
 278         #if YYDEBUG
 279         if (yydebug)
 280         {
 281         ...
 282         }
 283         #endif
 284
 285         into
 286
 287         if (yydebug)
 288         {
 289         ...
 290         }
 291
 292         unfortunately this leads to a CPP conflict when
 293         `--name-prefix=foo' is used since it produces `#define yydebug
 294         foodebug'.
 295
 296         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 297         (YYDPRINTF): New macro.
 298         Spread its use.
 299         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 300         the bison options.
 301         Also test `--verbose', `--defines' and `--name-prefix'.
 302
 303 2000-10-02  Akim Demaille  <akim@epita.fr>
 304
 305         Improve the readability of the produced parsers.
 306
 307         * src/bison.s1: Formatting changes.
 308         Improve the comment related to the `$' mark.
 309         (yydefault): Don't fall through to `yyresume': `goto' there.
 310         * src/output.c (output_parser): When the `$' is met, skip the end
 311         of its line.
 312         New variable, `number_of_dollar_signs', to check there's exactly
 313         one `$' in the parser skeleton.
 314
 315 2000-10-02  Akim Demaille  <akim@epita.fr>
 316
 317         * lib/xstrdup.c: New file, from the fileutils.
 318         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 319         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 320         instead of strlen + xmalloc + strcpy.
 321         * src/symtab.c (copys): Remove, use xstrdup instead.
 322
 323 2000-10-02  Akim Demaille  <akim@epita.fr>
 324
 325         * src/gram.h (associativity): New enum type which replaces the
 326         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 327         `right_assoc', `left_assoc' and `non_assoc'.
 328         Adjust all dependencies.
 329         * src/reader.c: Formatting changes.
 330         (LTYPESTR): Don't define it, use it as a literal in
 331         `reader_output_yylsp'.
 332         * src/symtab.h (symbol_class): New enum type which replaces the
 333         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 334         `sunknown', `stoken and `snterm'.
 335
 336 2000-10-02  Akim Demaille  <akim@epita.fr>
 337
 338         * src/getargs.c (fixed_outfiles): Rename as...
 339         (yaccflag): for consistency and accuracy.
 340         Adjust dependencies.
 341
 342 2000-10-02  Akim Demaille  <akim@epita.fr>
 343
 344         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 345         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 346         difficult and introduced a lot of core dump.  It turns out that
 347         Bison used an implementation of `xmalloc' based on `calloc', and
 348         at various places it does depend upon the initialization to 0.  I
 349         have not tried to isolate the pertinent places, and all the former
 350         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 351         someone should address this issue.
 352
 353         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 354         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 355         files.
 356         Adjust dependencies.
 357         * src/warshall.h: New file.
 358         Propagate.
 359
 360 2000-10-02  Akim Demaille  <akim@epita.fr>
 361
 362         Various anti-`extern in *.c' changes.
 363
 364         * src/system.h: Include `assert.h'.
 365
 366 2000-10-02  Akim Demaille  <akim@epita.fr>
 367
 368         * src/state.h (nstates, final_state, first_state, first_shift)
 369         (first_reduction): Move their exportation from here...
 370         * src/LR0.h: to here.
 371         Adjust dependencies.
 372         * src/getargs.c (statisticsflag): New variable.
 373         Add support for `--statistics'.
 374         Adjust dependencies.
 375
 376         Remove a lot of now useless `extern' statements in most files.
 377

 450         output_short_table.
 451
 452 2000-10-02  Akim Demaille  <akim@epita.fr>
 453
 454         `user_toknums' is output as a `short[]' in `output.c', while it is
 455         defined as a `int[]' in `reader.c'.  For consistency with the
 456         other output tables, `user_toknums' is now defined as a table of
 457         shorts.
 458
 459         * src/reader.c (user_toknums): Be a short table instead of an int
 460         table.

 472         order to get rid of the `static' prototypes.
 473         No longer use `register'.
 474         * src/output.h: New file.
 475         Propagate its inclusion in files explicitly prototyping functions
 476         from output.c.

 498         inclusion.
 499         Don't define PARAMS.
 500         * src/system.h: Define PARAMS.
 501         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 502         purpose of config.h.  system.h must not try to fix wrong
 503         definitions in config.h.

 638         * lib/: New directory.

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

 662 2000-03-17  Akim Demaille  <akim@epita.fr>
 663
 664         * src/Makefile.am (bison.simple): Fix the awk program: quote only
 665         the file name, not the whole `#line LINE FILE'.
 666
 667 2000-03-17  Akim Demaille  <akim@epita.fr>

 689
 690         * src/reader.c (copy_definition): Use copy_string and
 691         copy_comment.  Removed now unused `match', `ended',
 692         `cplus_comment'.
 693         (copy_comment, copy_string): Moved, to be visible from
 694         copy_definition.

 697
 698         * src/reader.c (copy_string): Declare `static inline'.  No

 720
 721         Change the handling of @s so that they behave exactly like $s.
 722         There is now a pseudo variable @$ (readble and writable), location
 723         of the lhs of the rule (by default ranging from the location of
 724         the first symbol of the rhs, to the location of the last symbol,
 725         or, if the rhs is empty, YYLLOC).
 726
 727         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
 728         yyval.
 729         (yyparse): When providing a default semantic action, provide a
 730         default location action.
 731         (after the $): No longer change `*YYLSP', just stack YYLOC the
 732         same way you stack YYVAL.
 733         * src/reader.c (read_declarations): Use warns.
 734         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
 735         (copy_action, case '@'): Likewise.
 736         Use a standard error message, to save useless work from
 737         translators.
 738
 739 2000-03-17  Akim Demaille  <akim@epita.fr>
 740

 748         Makefile now handles them.
 749

 751
 752         * src/output.c (output_rule_data): Output the documentation of
 753         some of the tables.
 754         (Copyright notice): Update.
 755         Formatting changes.
 756
 757 2000-03-16  Akim Demaille  <akim@epita.fr>
 758
 759         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
 760         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
 761         One `#if YYDEBUG' remains, since it uses variables which are
