  87         From Neil Booth.
  88
  89 2000-10-02  Paul Eggert  <eggert@twinsun.com>
  90
  91         * bison.s1 (yyparse): Assign the default value
  92         unconditionally, to avoid a GCC warning and make the parser a
  93         tad smaller.
  94
  95 2000-10-02  Akim Demaille  <akim@epita.fr>
  96
  97         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
  98         options.
  99
 100 2000-10-02  Akim Demaille  <akim@epita.fr>
 101
 102         * src/derives.c, src/print.c, src/reduce.c: To ease the
 103         translation, move some `\n' out of the translated strings.
 104
 105 2000-10-02  Akim Demaille  <akim@epita.fr>
 106
 107         The location tracking mechanism is precious for parse error
 108         messages.  Nevertheless, it is enabled only when `@n' is used in
 109         the grammar, which is a different issue (you can use it in error
 110         message, but not in the grammar per se).  Therefore, there should
 111         be another means to enable it.
 112
 113         * src/getargs.c (getargs): Support `--locations'.
 114         (usage): Report it.
 115         * src/getargs.h (locationsflag): Export it.
 116         * src/lex.c (percent_table): Support `%locations'.
 117         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 118         with `locationsflag'.
 119         * doc/bison.texinfo: Document `--locations' and `%locations'.
 120         Sort the options.
 121         * tests/calc.m4: Test it.
 122
 123         For regularity of the names, replace each
 124         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 125         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 126         In addition replace each `flag' with `_flag'.
 127
 128 2000-10-02  Akim Demaille  <akim@epita.fr>
 129
 130         Also test parse error messages, including with YYERROR_VERBOSE.
 131
 132         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 133         associative).
 134         Use it to check the computations.
 135         Use it to check `nonassoc' is honored.
 136         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 137         `--yyerror-verbose'.
 138         (_AT_CHECK_CALC): Adjust to this option.
 139         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 140
 141 2000-10-02  Akim Demaille  <akim@epita.fr>
 142
 143         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 144         the latter demonstrates a flaw in the handling of non debugging
 145         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 146         was used in order to simplify:
 147
 148         #if YYDEBUG
 149         if (yydebug)
 150         {
 151         ...
 152         }
 153         #endif
 154
 155         into
 156
 157         if (yydebug)
 158         {
 159         ...
 160         }
 161
 162         unfortunately this leads to a CPP conflict when
 163         `--name-prefix=foo' is used since it produces `#define yydebug
 164         foodebug'.
 165
 166         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 167         (YYDPRINTF): New macro.
 168         Spread its use.
 169         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 170         the bison options.
 171         Also test `--verbose', `--defines' and `--name-prefix'.
 172
 173 2000-10-02  Akim Demaille  <akim@epita.fr>
 174
 175         Improve the readability of the produced parsers.
 176
 177         * src/bison.s1: Formatting changes.
 178         Improve the comment related to the `$' mark.
 179         (yydefault): Don't fall through to `yyresume': `goto' there.
 180         * src/output.c (output_parser): When the `$' is met, skip the end
 181         of its line.
 182         New variable, `number_of_dollar_signs', to check there's exactly
 183         one `$' in the parser skeleton.
 184
 185 2000-10-02  Akim Demaille  <akim@epita.fr>
 186
 187         * lib/xstrdup.c: New file, from the fileutils.
 188         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 189         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 190         instead of strlen + xmalloc + strcpy.
 191         * src/symtab.c (copys): Remove, use xstrdup instead.
 192
 193 2000-10-02  Akim Demaille  <akim@epita.fr>
 194
 195         * src/gram.h (associativity): New enum type which replaces the
 196         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 197         `right_assoc', `left_assoc' and `non_assoc'.
 198         Adjust all dependencies.
 199         * src/reader.c: Formatting changes.
 200         (LTYPESTR): Don't define it, use it as a literal in
 201         `reader_output_yylsp'.
 202         * src/symtab.h (symbol_class): New enum type which replaces the
 203         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 204         `sunknown', `stoken and `snterm'.
 205
 206 2000-10-02  Akim Demaille  <akim@epita.fr>
 207
 208         * src/getargs.c (fixed_outfiles): Rename as...
 209         (yaccflag): for consistency and accuracy.
 210         Adjust dependencies.
 211
 212 2000-10-02  Akim Demaille  <akim@epita.fr>
 213
 214         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 215         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 216         difficult and introduced a lot of core dump.  It turns out that
 217         Bison used an implementation of `xmalloc' based on `calloc', and
 218         at various places it does depend upon the initialization to 0.  I
 219         have not tried to isolate the pertinent places, and all the former
 220         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 221         someone should address this issue.
 222
 223         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 224         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 225         files.
 226         Adjust dependencies.
 227         * src/warshall.h: New file.
 228         Propagate.
 229
 230 2000-10-02  Akim Demaille  <akim@epita.fr>
 231
 232         Various anti-`extern in *.c' changes.
 233
 234         * src/system.h: Include `assert.h'.
 235
 236 2000-10-02  Akim Demaille  <akim@epita.fr>
 237
 238         * src/state.h (nstates, final_state, first_state, first_shift)
 239         (first_reduction): Move their exportation from here...
 240         * src/LR0.h: to here.
 241         Adjust dependencies.
 242         * src/getargs.c (statisticsflag): New variable.
 243         Add support for `--statistics'.
 244         Adjust dependencies.
 245
 246         Remove a lot of now useless `extern' statements in most files.
 247
 248 2000-10-02  Akim Demaille  <akim@epita.fr>
 249
 250         * src/LR0.h: New file.
 251         Propagate its use.
 252
 253 2000-10-02  Akim Demaille  <akim@epita.fr>

 255         * src/print.h: New file.
 256         Propagate its use.
 257         * src/print.c: Formatting and ordering changes.
 258         (verbose, terse): Replace with...
 259         (print_results): this new function.
 260         Adjust dependencies.
 261
 262 2000-10-02  Akim Demaille  <akim@epita.fr>
 263
 264         * src/conflicts.c (conflict_report): New function.
 265         (conflict_log, verbose_conflict_log): Replace with...
 266         (print_conflicts): this function.
 267         Adjust dependencies.

 276
 277 2000-10-02  Akim Demaille  <akim@epita.fr>

 285 2000-10-02  Akim Demaille  <akim@epita.fr>
 286
 287         * src/files.c: Formatting changes.
 288         (tryopen, tryclose, openfiles): Rename as...
 289         (xfopen, xfclose, open_files): this.
 290         (stringappend): static.
 291         * src/files.h: Complete the list of exported symbols.
 292         Propagate its use.
 293
 294 2000-10-02  Akim Demaille  <akim@epita.fr>
 295
 296         * src/reader.h: New file.
 297         Propagate its use instead of tedious list of `extern' and

 299         * src/reader.c: Formatting changes, topological sort,
 300         s/register//.
 301
 302 2000-10-02  Akim Demaille  <akim@epita.fr>
 303
 304         * src/lex.h: Prototype `lex.c' exported functions.

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

 533
 534         * src/Makefile.am (bison.simple): Fix the awk program: quote only

 561         copy_comment.  Removed now unused `match', `ended',
 562         `cplus_comment'.

 590
 591         Change the handling of @s so that they behave exactly like $s.
 592         There is now a pseudo variable @$ (readble and writable), location
 593         of the lhs of the rule (by default ranging from the location of
 594         the first symbol of the rhs, to the location of the last symbol,
 595         or, if the rhs is empty, YYLLOC).
 596

 598         yyval.
 599         (yyparse): When providing a default semantic action, provide a
 600         default location action.
 601         (after the $): No longer change `*YYLSP', just stack YYLOC the
 602         same way you stack YYVAL.
 603         * src/reader.c (read_declarations): Use warns.
 604         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
 605         (copy_action, case '@'): Likewise.
 606         Use a standard error message, to save useless work from
 607         translators.

 628
 629         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
 630         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
 631         One `#if YYDEBUG' remains, since it uses variables which are
 632         defined only if `YYDEBUG != 0'.
 633
 634 2000-03-16  Akim Demaille  <akim@epita.fr>
 635

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

 668         locale files.
 669         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
 670         builddir.
 671         * acinclude.m4: Remove, replaced by the directory m4.
 672         * m4/Makefile.am (EXTRA_DIST): New variable.

1360         major changes to files.c.
