  81
  82 2000-10-04  Akim Demaille  <akim@epita.fr>
  83
  84         When a literal string is used to define two different tokens,
  85         `bison -v' segfaults.
  86         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
  87
  88         * tests/regression.m4: New file.

  95         * src/reader.c (parse_expect_decl): Keep `count' within the size

  97         From Neil Booth.
  98
  99 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 100
 101         * bison.s1 (yyparse): Assign the default value
 102         unconditionally, to avoid a GCC warning and make the parser a
 103         tad smaller.
 104
 105 2000-10-02  Akim Demaille  <akim@epita.fr>
 106
 107         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
 108         options.
 109
 110 2000-10-02  Akim Demaille  <akim@epita.fr>
 111
 112         * src/derives.c, src/print.c, src/reduce.c: To ease the
 113         translation, move some `\n' out of the translated strings.
 114
 115 2000-10-02  Akim Demaille  <akim@epita.fr>
 116
 117         The location tracking mechanism is precious for parse error
 118         messages.  Nevertheless, it is enabled only when `@n' is used in
 119         the grammar, which is a different issue (you can use it in error
 120         message, but not in the grammar per se).  Therefore, there should
 121         be another means to enable it.
 122
 123         * src/getargs.c (getargs): Support `--locations'.
 124         (usage): Report it.
 125         * src/getargs.h (locationsflag): Export it.
 126         * src/lex.c (percent_table): Support `%locations'.
 127         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 128         with `locationsflag'.
 129         * doc/bison.texinfo: Document `--locations' and `%locations'.
 130         Sort the options.
 131         * tests/calc.m4: Test it.
 132
 133         For regularity of the names, replace each
 134         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 135         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 136         In addition replace each `flag' with `_flag'.
 137
 138 2000-10-02  Akim Demaille  <akim@epita.fr>
 139
 140         Also test parse error messages, including with YYERROR_VERBOSE.
 141
 142         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 143         associative).
 144         Use it to check the computations.
 145         Use it to check `nonassoc' is honored.
 146         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 147         `--yyerror-verbose'.
 148         (_AT_CHECK_CALC): Adjust to this option.
 149         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 150
 151 2000-10-02  Akim Demaille  <akim@epita.fr>
 152
 153         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 154         the latter demonstrates a flaw in the handling of non debugging
 155         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 156         was used in order to simplify:
 157
 158         #if YYDEBUG
 159         if (yydebug)
 160         {
 161         ...
 162         }
 163         #endif
 164
 165         into
 166
 167         if (yydebug)
 168         {
 169         ...
 170         }
 171
 172         unfortunately this leads to a CPP conflict when
 173         `--name-prefix=foo' is used since it produces `#define yydebug
 174         foodebug'.
 175
 176         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 177         (YYDPRINTF): New macro.
 178         Spread its use.
 179         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 180         the bison options.
 181         Also test `--verbose', `--defines' and `--name-prefix'.
 182
 183 2000-10-02  Akim Demaille  <akim@epita.fr>
 184
 185         Improve the readability of the produced parsers.
 186
 187         * src/bison.s1: Formatting changes.
 188         Improve the comment related to the `$' mark.
 189         (yydefault): Don't fall through to `yyresume': `goto' there.
 190         * src/output.c (output_parser): When the `$' is met, skip the end
 191         of its line.
 192         New variable, `number_of_dollar_signs', to check there's exactly
 193         one `$' in the parser skeleton.
 194
 195 2000-10-02  Akim Demaille  <akim@epita.fr>
 196
 197         * lib/xstrdup.c: New file, from the fileutils.
 198         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 199         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 200         instead of strlen + xmalloc + strcpy.
 201         * src/symtab.c (copys): Remove, use xstrdup instead.
 202
 203 2000-10-02  Akim Demaille  <akim@epita.fr>
 204
 205         * src/gram.h (associativity): New enum type which replaces the
 206         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 207         `right_assoc', `left_assoc' and `non_assoc'.
 208         Adjust all dependencies.
 209         * src/reader.c: Formatting changes.
 210         (LTYPESTR): Don't define it, use it as a literal in
 211         `reader_output_yylsp'.
 212         * src/symtab.h (symbol_class): New enum type which replaces the
 213         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 214         `sunknown', `stoken and `snterm'.
 215
 216 2000-10-02  Akim Demaille  <akim@epita.fr>
 217
 218         * src/getargs.c (fixed_outfiles): Rename as...
 219         (yaccflag): for consistency and accuracy.
 220         Adjust dependencies.
 221
 222 2000-10-02  Akim Demaille  <akim@epita.fr>
 223
 224         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 225         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 226         difficult and introduced a lot of core dump.  It turns out that
 227         Bison used an implementation of `xmalloc' based on `calloc', and
 228         at various places it does depend upon the initialization to 0.  I
 229         have not tried to isolate the pertinent places, and all the former
 230         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 231         someone should address this issue.
 232
 233         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 234         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 235         files.
 236         Adjust dependencies.
 237         * src/warshall.h: New file.
 238         Propagate.
 239
 240 2000-10-02  Akim Demaille  <akim@epita.fr>
 241
 242         Various anti-`extern in *.c' changes.
 243
 244         * src/system.h: Include `assert.h'.
 245
 246 2000-10-02  Akim Demaille  <akim@epita.fr>
 247
 248         * src/state.h (nstates, final_state, first_state, first_shift)
 249         (first_reduction): Move their exportation from here...
 250         * src/LR0.h: to here.
 251         Adjust dependencies.
 252         * src/getargs.c (statisticsflag): New variable.
 253         Add support for `--statistics'.
 254         Adjust dependencies.
 255
 256         Remove a lot of now useless `extern' statements in most files.
 257
 258 2000-10-02  Akim Demaille  <akim@epita.fr>
 259
 260         * src/LR0.h: New file.
 261         Propagate its use.
 262
 263 2000-10-02  Akim Demaille  <akim@epita.fr>
 264
 265         * src/print.h: New file.
 266         Propagate its use.
 267         * src/print.c: Formatting and ordering changes.
 268         (verbose, terse): Replace with...
 269         (print_results): this new function.
 270         Adjust dependencies.
 271
 272 2000-10-02  Akim Demaille  <akim@epita.fr>
 273
 274         * src/conflicts.c (conflict_report): New function.
 275         (conflict_log, verbose_conflict_log): Replace with...
 276         (print_conflicts): this function.
 277         Adjust dependencies.

 294
 295 2000-10-02  Akim Demaille  <akim@epita.fr>
 296
 297         * src/files.c: Formatting changes.
 298         (tryopen, tryclose, openfiles): Rename as...
 299         (xfopen, xfclose, open_files): this.
 300         (stringappend): static.
 301         * src/files.h: Complete the list of exported symbols.
 302         Propagate its use.
 303
 304 2000-10-02  Akim Demaille  <akim@epita.fr>
 305
 306         * src/reader.h: New file.
 307         Propagate its use instead of tedious list of `extern' and
 308         prototypes.
 309         * src/reader.c: Formatting changes, topological sort,
 310         s/register//.
 311
 312 2000-10-02  Akim Demaille  <akim@epita.fr>
 313
 314         * src/lex.h: Prototype `lex.c' exported functions.
 315         * src/reader.c: Adjust.
 316         * src/lex.c: Formatting changes.
 317         (safegetc): Rename as...
 318         (xgetc): this.
 319
 320 2000-10-02  Akim Demaille  <akim@epita.fr>
 321
 322         * src/lalr.h: New file.
 323         Propagate its inclusion instead of prototypes and `extern'.
 324         * src/lalr.c: Formatting changes, topological sorting etc.
 325
 326 2000-10-02  Akim Demaille  <akim@epita.fr>
 327
 328         * src/output.c (token_actions): Introduce a temporary array,
 329         YYDEFACT, that makes it possible for this function to use
 330         output_short_table.
 331
 332 2000-10-02  Akim Demaille  <akim@epita.fr>
 333
 334         `user_toknums' is output as a `short[]' in `output.c', while it is
 335         defined as a `int[]' in `reader.c'.  For consistency with the
 336         other output tables, `user_toknums' is now defined as a table of
 337         shorts.
 338
 339         * src/reader.c (user_toknums): Be a short table instead of an int
 340         table.
 341         Adjust dependencies.
 342
 343         Factor the short table outputs.
 344
 345         * src/output.c (output_short_table): New function.
 346         * src/output.c (output_gram, output_stos, output_rule_data)
 347         (output_base, output_table, output_check):  Use it.
 348
 349 2000-10-02  Akim Demaille  <akim@epita.fr>
 350
 351         * src/output.c (output): Topological sort of the functions, in
 352         order to get rid of the `static' prototypes.
 353         No longer use `register'.
 354         * src/output.h: New file.
 355         Propagate its inclusion in files explicitly prototyping functions
 356         from output.c.
 357
 358 2000-09-21  Akim Demaille  <akim@epita.fr>
 359
 360         * src/atgeneral.m4: Update from Autoconf.
 361
 362 2000-09-21  Akim Demaille  <akim@epita.fr>
 363
 364         * src/closure.h: New file.
 365         * src/closure.c: Formatting changes, topological sort over the
 366         functions, use of closure.h.
 367         (initialize_closure, finalize_closure):  Rename as...
 368         (new_closure, free_closure): these.  Adjust dependencies.
 369         * src/LR0.c: Formatting changes, topological sort, use of
 370         cloture.h.
 371         (initialize_states): Rename as...
 372         (new_states): this.
 373         * src/Makefile.am (noinst_HEADERS): Adjust.
 374
 375 2000-09-20  Akim Demaille  <akim@epita.fr>
 376
 377         * src/acconfig.h: Don't protect config.h against multiple
 378         inclusion.
 379         Don't define PARAMS.
 380         * src/system.h: Define PARAMS.
 381         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 382         purpose of config.h.  system.h must not try to fix wrong
 383         definitions in config.h.
 384
 385 2000-09-20  Akim Demaille  <akim@epita.fr>

 543
 544         * src/Makefile.am (bison.simple): Fix the awk program: quote only

 571         copy_comment.  Removed now unused `match', `ended',
 572         `cplus_comment'.

 600
 601         Change the handling of @s so that they behave exactly like $s.
 602         There is now a pseudo variable @$ (readble and writable), location
 603         of the lhs of the rule (by default ranging from the location of
 604         the first symbol of the rhs, to the location of the last symbol,
 605         or, if the rhs is empty, YYLLOC).
 606

 608         yyval.
 609         (yyparse): When providing a default semantic action, provide a
 610         default location action.
 611         (after the $): No longer change `*YYLSP', just stack YYLOC the
 612         same way you stack YYVAL.
 613         * src/reader.c (read_declarations): Use warns.
 614         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
 615         (copy_action, case '@'): Likewise.
 616         Use a standard error message, to save useless work from
 617         translators.

 638
 639         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
 640         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
 641         One `#if YYDEBUG' remains, since it uses variables which are
 642         defined only if `YYDEBUG != 0'.
 643
 644 2000-03-16  Akim Demaille  <akim@epita.fr>
 645

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

 678         locale files.
 679         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
 680         builddir.
 681         * acinclude.m4: Remove, replaced by the directory m4.
 682         * m4/Makefile.am (EXTRA_DIST): New variable.

1370         major changes to files.c.
