  32
  33         For some reason, this was not applied.
  34
  35         * src/files.c [VMS]: No longer include `ssdef.h', no longer define
  36         `unlink': it's no longer used.

  39
  40         * src/files.c (skeleton_find): New function, eved out of...

  48         (done): Rename as...
  49         (output_files): this.
  50         Use `obstack_save'.
  51         * src/main.c (main): Don't use `atexit' to register `done', since
  52         it no longer has to remove tmp files, just call `output_files'
  53         when there are no errors.

 123
 124         * src/reader.c (copy_comment2): Expect the input stream to be on
 125         the `/' which is suspected to open a comment, instead of being

 153
 154         * doc/bison.texinfo: Various typos spotted by Neil Booth.
 155
 156 2000-10-04  Akim Demaille  <akim@epita.fr>
 157
 158         When a literal string is used to define two different tokens,
 159         `bison -v' segfaults.
 160         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 161
 162         * tests/regression.m4: New file.
 163         Include the core of the sample provided by Piotr Gackiewicz.
 164         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
 165         properly.
 166
 167 2000-10-04  Akim Demaille  <akim@epita.fr>
 168
 169         * src/reader.c (parse_expect_decl): Keep `count' within the size
 170         of `buffer'.
 171         From Neil Booth.
 172
 173 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 174
 175         * bison.s1 (yyparse): Assign the default value
 176         unconditionally, to avoid a GCC warning and make the parser a
 177         tad smaller.
 178
 179 2000-10-02  Akim Demaille  <akim@epita.fr>
 180
 181         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
 182         options.
 183
 184 2000-10-02  Akim Demaille  <akim@epita.fr>
 185
 186         * src/derives.c, src/print.c, src/reduce.c: To ease the
 187         translation, move some `\n' out of the translated strings.
 188
 189 2000-10-02  Akim Demaille  <akim@epita.fr>
 190
 191         The location tracking mechanism is precious for parse error
 192         messages.  Nevertheless, it is enabled only when `@n' is used in
 193         the grammar, which is a different issue (you can use it in error
 194         message, but not in the grammar per se).  Therefore, there should
 195         be another means to enable it.
 196
 197         * src/getargs.c (getargs): Support `--locations'.
 198         (usage): Report it.
 199         * src/getargs.h (locationsflag): Export it.
 200         * src/lex.c (percent_table): Support `%locations'.
 201         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 202         with `locationsflag'.
 203         * doc/bison.texinfo: Document `--locations' and `%locations'.
 204         Sort the options.
 205         * tests/calc.m4: Test it.
 206
 207         For regularity of the names, replace each
 208         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 209         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 210         In addition replace each `flag' with `_flag'.
 211
 212 2000-10-02  Akim Demaille  <akim@epita.fr>
 213
 214         Also test parse error messages, including with YYERROR_VERBOSE.
 215
 216         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 217         associative).
 218         Use it to check the computations.
 219         Use it to check `nonassoc' is honored.
 220         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 221         `--yyerror-verbose'.
 222         (_AT_CHECK_CALC): Adjust to this option.
 223         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 224
 225 2000-10-02  Akim Demaille  <akim@epita.fr>
 226
 227         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 228         the latter demonstrates a flaw in the handling of non debugging
 229         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 230         was used in order to simplify:
 231
 232         #if YYDEBUG
 233         if (yydebug)
 234         {
 235         ...
 236         }
 237         #endif
 238
 239         into
 240
 241         if (yydebug)
 242         {
 243         ...
 244         }
 245
 246         unfortunately this leads to a CPP conflict when
 247         `--name-prefix=foo' is used since it produces `#define yydebug
 248         foodebug'.
 249
 250         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 251         (YYDPRINTF): New macro.
 252         Spread its use.
 253         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 254         the bison options.
 255         Also test `--verbose', `--defines' and `--name-prefix'.
 256
 257 2000-10-02  Akim Demaille  <akim@epita.fr>
 258
 259         Improve the readability of the produced parsers.
 260
 261         * src/bison.s1: Formatting changes.
 262         Improve the comment related to the `$' mark.
 263         (yydefault): Don't fall through to `yyresume': `goto' there.
 264         * src/output.c (output_parser): When the `$' is met, skip the end
 265         of its line.
 266         New variable, `number_of_dollar_signs', to check there's exactly
 267         one `$' in the parser skeleton.
 268
 269 2000-10-02  Akim Demaille  <akim@epita.fr>
 270
 271         * lib/xstrdup.c: New file, from the fileutils.
 272         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 273         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 274         instead of strlen + xmalloc + strcpy.
 275         * src/symtab.c (copys): Remove, use xstrdup instead.
 276
 277 2000-10-02  Akim Demaille  <akim@epita.fr>
 278
 279         * src/gram.h (associativity): New enum type which replaces the
 280         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 281         `right_assoc', `left_assoc' and `non_assoc'.
 282         Adjust all dependencies.
 283         * src/reader.c: Formatting changes.
 284         (LTYPESTR): Don't define it, use it as a literal in
 285         `reader_output_yylsp'.
 286         * src/symtab.h (symbol_class): New enum type which replaces the
 287         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 288         `sunknown', `stoken and `snterm'.
 289
 290 2000-10-02  Akim Demaille  <akim@epita.fr>
 291
 292         * src/getargs.c (fixed_outfiles): Rename as...
 293         (yaccflag): for consistency and accuracy.
 294         Adjust dependencies.
 295
 296 2000-10-02  Akim Demaille  <akim@epita.fr>
 297
 298         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 299         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 300         difficult and introduced a lot of core dump.  It turns out that
 301         Bison used an implementation of `xmalloc' based on `calloc', and
 302         at various places it does depend upon the initialization to 0.  I
 303         have not tried to isolate the pertinent places, and all the former
 304         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 305         someone should address this issue.
 306
 307         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 308         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 309         files.
 310         Adjust dependencies.
 311         * src/warshall.h: New file.
 312         Propagate.
 313
 314 2000-10-02  Akim Demaille  <akim@epita.fr>
 315
 316         Various anti-`extern in *.c' changes.
 317
 318         * src/system.h: Include `assert.h'.
 319
 320 2000-10-02  Akim Demaille  <akim@epita.fr>
 321
 322         * src/state.h (nstates, final_state, first_state, first_shift)
 323         (first_reduction): Move their exportation from here...
 324         * src/LR0.h: to here.
 325         Adjust dependencies.
 326         * src/getargs.c (statisticsflag): New variable.
 327         Add support for `--statistics'.
 328         Adjust dependencies.
 329
 330         Remove a lot of now useless `extern' statements in most files.
 331
 332 2000-10-02  Akim Demaille  <akim@epita.fr>
 333
 334         * src/LR0.h: New file.

 341         * src/print.c: Formatting and ordering changes.
 342         (verbose, terse): Replace with...
 343         (print_results): this new function.
 344         Adjust dependencies.
 345
 346 2000-10-02  Akim Demaille  <akim@epita.fr>
 347
 348         * src/conflicts.c (conflict_report): New function.
 349         (conflict_log, verbose_conflict_log): Replace with...
 350         (print_conflicts): this function.

 370
 371         * src/files.c: Formatting changes.
 372         (tryopen, tryclose, openfiles): Rename as...
 373         (xfopen, xfclose, open_files): this.
 374         (stringappend): static.
 375         * src/files.h: Complete the list of exported symbols.
 376         Propagate its use.
 377

 384         s/register//.
 385
 386 2000-10-02  Akim Demaille  <akim@epita.fr>
 387
 388         * src/lex.h: Prototype `lex.c' exported functions.
 389         * src/reader.c: Adjust.
 390         * src/lex.c: Formatting changes.
 391         (safegetc): Rename as...
 392         (xgetc): this.
 393
 394 2000-10-02  Akim Demaille  <akim@epita.fr>
 395
 396         * src/lalr.h: New file.

 399
 400 2000-10-02  Akim Demaille  <akim@epita.fr>
 401
 402         * src/output.c (token_actions): Introduce a temporary array,
 403         YYDEFACT, that makes it possible for this function to use
 404         output_short_table.
 405
 406 2000-10-02  Akim Demaille  <akim@epita.fr>
 407
 408         `user_toknums' is output as a `short[]' in `output.c', while it is
 409         defined as a `int[]' in `reader.c'.  For consistency with the
 410         other output tables, `user_toknums' is now defined as a table of
 411         shorts.
 412
 413         * src/reader.c (user_toknums): Be a short table instead of an int
 414         table.
 415         Adjust dependencies.
 416
 417         Factor the short table outputs.
 418
 419         * src/output.c (output_short_table): New function.

 423 2000-10-02  Akim Demaille  <akim@epita.fr>
 424
 425         * src/output.c (output): Topological sort of the functions, in
 426         order to get rid of the `static' prototypes.
 427         No longer use `register'.
 428         * src/output.h: New file.
 429         Propagate its inclusion in files explicitly prototyping functions
 430         from output.c.
 431
 432 2000-09-21  Akim Demaille  <akim@epita.fr>

 448
 449 2000-09-20  Akim Demaille  <akim@epita.fr>
 450

 452         inclusion.
 453         Don't define PARAMS.
 454         * src/system.h: Define PARAMS.
 455         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 456         purpose of config.h.  system.h must not try to fix wrong
 457         definitions in config.h.
 458
 459 2000-09-20  Akim Demaille  <akim@epita.fr>

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

 497

 590 2000-03-28  Akim Demaille  <akim@epita.fr>
 591
 592         * lib/: New directory.

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

 615
 616 2000-03-17  Akim Demaille  <akim@epita.fr>
 617
 618         * src/Makefile.am (bison.simple): Fix the awk program: quote only
 619         the file name, not the whole `#line LINE FILE'.
 620
 621 2000-03-17  Akim Demaille  <akim@epita.fr>
 622
 623         On syntax errors, report the token on which we choked.

 643
 644         * src/reader.c (copy_definition): Use copy_string and
 645         copy_comment.  Removed now unused `match', `ended',
 646         `cplus_comment'.
 647         (copy_comment, copy_string): Moved, to be visible from
 648         copy_definition.

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

 672
 673 2000-03-17  Akim Demaille  <akim@epita.fr>
 674
 675         Change the handling of @s so that they behave exactly like $s.
 676         There is now a pseudo variable @$ (readble and writable), location
 677         of the lhs of the rule (by default ranging from the location of
 678         the first symbol of the rhs, to the location of the last symbol,
 679         or, if the rhs is empty, YYLLOC).
 680
 681         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
 682         yyval.
 683         (yyparse): When providing a default semantic action, provide a
 684         default location action.
 685         (after the $): No longer change `*YYLSP', just stack YYLOC the
 686         same way you stack YYVAL.
 687         * src/reader.c (read_declarations): Use warns.
 688         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
 689         (copy_action, case '@'): Likewise.
 690         Use a standard error message, to save useless work from
 691         translators.
 692
 693 2000-03-17  Akim Demaille  <akim@epita.fr>
 694
 695         * src/bison.s1: Formatting and cosmetics changes.

 711 2000-03-16  Akim Demaille  <akim@epita.fr>
 712
 713         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
 714         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
 715         One `#if YYDEBUG' remains, since it uses variables which are
 716         defined only if `YYDEBUG != 0'.
 717
 718 2000-03-16  Akim Demaille  <akim@epita.fr>
 719
 720         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

 735
 736         * configure.in (XPFILE, XPFILE1, LOCALEDIR): Remove, handled by

 742         handled via src/Makefile.am.
 743         (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
 744         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

 750         the proper line number and file name.
 751         (DEFS): Propagate the location of bison library files and of the
 752         locale files.
 753         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
 754         builddir.
 755         * acinclude.m4: Remove, replaced by the directory m4.
 756         * m4/Makefile.am (EXTRA_DIST): New variable.
 757         * m4/gettext.m4: New file, from the fileutils.
