   9
  10         * src/reader.c (copy_comment2): Expect the input stream to be on
  11         the `/' which is suspected to open a comment, instead of being
  12         called after `//' or `/*' was read.

  47         When a literal string is used to define two different tokens,
  48         `bison -v' segfaults.

  60         From Neil Booth.
  61
  62 2000-10-02  Paul Eggert  <eggert@twinsun.com>
  63
  64         * bison.s1 (yyparse): Assign the default value
  65         unconditionally, to avoid a GCC warning and make the parser a
  66         tad smaller.
  67
  68 2000-10-02  Akim Demaille  <akim@epita.fr>
  69
  70         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
  71         options.
  72
  73 2000-10-02  Akim Demaille  <akim@epita.fr>
  74
  75         * src/derives.c, src/print.c, src/reduce.c: To ease the
  76         translation, move some `\n' out of the translated strings.
  77
  78 2000-10-02  Akim Demaille  <akim@epita.fr>
  79
  80         The location tracking mechanism is precious for parse error
  81         messages.  Nevertheless, it is enabled only when `@n' is used in
  82         the grammar, which is a different issue (you can use it in error
  83         message, but not in the grammar per se).  Therefore, there should
  84         be another means to enable it.
  85
  86         * src/getargs.c (getargs): Support `--locations'.
  87         (usage): Report it.
  88         * src/getargs.h (locationsflag): Export it.
  89         * src/lex.c (percent_table): Support `%locations'.
  90         * src/reader.c (yylsp_needed): Remove this variable, now replaced
  91         with `locationsflag'.
  92         * doc/bison.texinfo: Document `--locations' and `%locations'.
  93         Sort the options.
  94         * tests/calc.m4: Test it.
  95
  96         For regularity of the names, replace each
  97         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
  98         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
  99         In addition replace each `flag' with `_flag'.
 100
 101 2000-10-02  Akim Demaille  <akim@epita.fr>
 102
 103         Also test parse error messages, including with YYERROR_VERBOSE.
 104
 105         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 106         associative).
 107         Use it to check the computations.
 108         Use it to check `nonassoc' is honored.
 109         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 110         `--yyerror-verbose'.
 111         (_AT_CHECK_CALC): Adjust to this option.
 112         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 113
 114 2000-10-02  Akim Demaille  <akim@epita.fr>
 115
 116         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 117         the latter demonstrates a flaw in the handling of non debugging
 118         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 119         was used in order to simplify:
 120
 121         #if YYDEBUG
 122         if (yydebug)
 123         {
 124         ...
 125         }
 126         #endif
 127
 128         into
 129
 130         if (yydebug)
 131         {
 132         ...
 133         }
 134
 135         unfortunately this leads to a CPP conflict when
 136         `--name-prefix=foo' is used since it produces `#define yydebug
 137         foodebug'.
 138
 139         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 140         (YYDPRINTF): New macro.
 141         Spread its use.
 142         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 143         the bison options.
 144         Also test `--verbose', `--defines' and `--name-prefix'.
 145
 146 2000-10-02  Akim Demaille  <akim@epita.fr>
 147
 148         Improve the readability of the produced parsers.
 149
 150         * src/bison.s1: Formatting changes.
 151         Improve the comment related to the `$' mark.
 152         (yydefault): Don't fall through to `yyresume': `goto' there.
 153         * src/output.c (output_parser): When the `$' is met, skip the end
 154         of its line.
 155         New variable, `number_of_dollar_signs', to check there's exactly
 156         one `$' in the parser skeleton.
 157
 158 2000-10-02  Akim Demaille  <akim@epita.fr>
 159
 160         * lib/xstrdup.c: New file, from the fileutils.
 161         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 162         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 163         instead of strlen + xmalloc + strcpy.
 164         * src/symtab.c (copys): Remove, use xstrdup instead.
 165
 166 2000-10-02  Akim Demaille  <akim@epita.fr>
 167
 168         * src/gram.h (associativity): New enum type which replaces the
 169         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 170         `right_assoc', `left_assoc' and `non_assoc'.
 171         Adjust all dependencies.
 172         * src/reader.c: Formatting changes.
 173         (LTYPESTR): Don't define it, use it as a literal in
 174         `reader_output_yylsp'.
 175         * src/symtab.h (symbol_class): New enum type which replaces the
 176         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 177         `sunknown', `stoken and `snterm'.
 178
 179 2000-10-02  Akim Demaille  <akim@epita.fr>
 180
 181         * src/getargs.c (fixed_outfiles): Rename as...
 182         (yaccflag): for consistency and accuracy.
 183         Adjust dependencies.
 184
 185 2000-10-02  Akim Demaille  <akim@epita.fr>
 186
 187         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 188         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 189         difficult and introduced a lot of core dump.  It turns out that
 190         Bison used an implementation of `xmalloc' based on `calloc', and
 191         at various places it does depend upon the initialization to 0.  I
 192         have not tried to isolate the pertinent places, and all the former
 193         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 194         someone should address this issue.
 195
 196         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 197         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 198         files.
 199         Adjust dependencies.
 200         * src/warshall.h: New file.
 201         Propagate.
 202
 203 2000-10-02  Akim Demaille  <akim@epita.fr>
 204
 205         Various anti-`extern in *.c' changes.
 206
 207         * src/system.h: Include `assert.h'.
 208
 209 2000-10-02  Akim Demaille  <akim@epita.fr>
 210
 211         * src/state.h (nstates, final_state, first_state, first_shift)
 212         (first_reduction): Move their exportation from here...
 213         * src/LR0.h: to here.
 214         Adjust dependencies.
 215         * src/getargs.c (statisticsflag): New variable.
 216         Add support for `--statistics'.
 217         Adjust dependencies.
 218
 219         Remove a lot of now useless `extern' statements in most files.
 220
 221 2000-10-02  Akim Demaille  <akim@epita.fr>
 222
 223         * src/LR0.h: New file.
 224         Propagate its use.
 225
 226 2000-10-02  Akim Demaille  <akim@epita.fr>
 227
 228         * src/print.h: New file.
 229         Propagate its use.
 230         * src/print.c: Formatting and ordering changes.
 231         (verbose, terse): Replace with...
 232         (print_results): this new function.
 233         Adjust dependencies.
 234
 235 2000-10-02  Akim Demaille  <akim@epita.fr>
 236
 237         * src/conflicts.c (conflict_report): New function.
 238         (conflict_log, verbose_conflict_log): Replace with...
 239         (print_conflicts): this function.

 249
 250 2000-10-02  Akim Demaille  <akim@epita.fr>
 251
 252         * src/reduce.h: New file.
 253         Propagate its inclusion.
 254         * src/reduce.c: Topological sort and other formatting changes.

 257
 258 2000-10-02  Akim Demaille  <akim@epita.fr>
 259
 260         * src/files.c: Formatting changes.
 261         (tryopen, tryclose, openfiles): Rename as...
 262         (xfopen, xfclose, open_files): this.
 263         (stringappend): static.
 264         * src/files.h: Complete the list of exported symbols.
 265         Propagate its use.
 266
 267 2000-10-02  Akim Demaille  <akim@epita.fr>
 268
 269         * src/reader.h: New file.
 270         Propagate its use instead of tedious list of `extern' and
 271         prototypes.
 272         * src/reader.c: Formatting changes, topological sort,
 273         s/register//.
 274
 275 2000-10-02  Akim Demaille  <akim@epita.fr>
 276
 277         * src/lex.h: Prototype `lex.c' exported functions.

 280         (safegetc): Rename as...
 281         (xgetc): this.
 282
 283 2000-10-02  Akim Demaille  <akim@epita.fr>
 284
 285         * src/lalr.h: New file.
 286         Propagate its inclusion instead of prototypes and `extern'.
 287         * src/lalr.c: Formatting changes, topological sorting etc.
 288
 289 2000-10-02  Akim Demaille  <akim@epita.fr>
 290
 291         * src/output.c (token_actions): Introduce a temporary array,
 292         YYDEFACT, that makes it possible for this function to use
 293         output_short_table.
 294
 295 2000-10-02  Akim Demaille  <akim@epita.fr>
 296
 297         `user_toknums' is output as a `short[]' in `output.c', while it is
 298         defined as a `int[]' in `reader.c'.  For consistency with the
 299         other output tables, `user_toknums' is now defined as a table of
 300         shorts.
 301
 302         * src/reader.c (user_toknums): Be a short table instead of an int
 303         table.
 304         Adjust dependencies.
 305
 306         Factor the short table outputs.
 307
 308         * src/output.c (output_short_table): New function.
 309         * src/output.c (output_gram, output_stos, output_rule_data)

 311
 312 2000-10-02  Akim Demaille  <akim@epita.fr>
 313
 314         * src/output.c (output): Topological sort of the functions, in
 315         order to get rid of the `static' prototypes.
 316         No longer use `register'.
 317         * src/output.h: New file.
 318         Propagate its inclusion in files explicitly prototyping functions
 319         from output.c.
 320
 321 2000-09-21  Akim Demaille  <akim@epita.fr>
 322
 323         * src/atgeneral.m4: Update from Autoconf.
 324
 325 2000-09-21  Akim Demaille  <akim@epita.fr>
 326
 327         * src/closure.h: New file.
 328         * src/closure.c: Formatting changes, topological sort over the
 329         functions, use of closure.h.
 330         (initialize_closure, finalize_closure):  Rename as...
 331         (new_closure, free_closure): these.  Adjust dependencies.
 332         * src/LR0.c: Formatting changes, topological sort, use of
 333         cloture.h.
 334         (initialize_states): Rename as...
 335         (new_states): this.
 336         * src/Makefile.am (noinst_HEADERS): Adjust.
 337
 338 2000-09-20  Akim Demaille  <akim@epita.fr>
 339
 340         * src/acconfig.h: Don't protect config.h against multiple
 341         inclusion.
 342         Don't define PARAMS.
 343         * src/system.h: Define PARAMS.
 344         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 345         purpose of config.h.  system.h must not try to fix wrong
 346         definitions in config.h.
 347
 348 2000-09-20  Akim Demaille  <akim@epita.fr>
 349
 350         * src/derives.h: New file.
 351         * src/main.c, src/derives.h: Use it.

 353         * src/Makefile.am (noinst_HEADERS): Adjust.
 354
 355 2000-09-20  Akim Demaille  <akim@epita.fr>
 356
 357         * tests/atgeneral.m4: Update from Autoconf.
 358         * tests/calc.m4 (_AT_DATA_CALC_Y, AT_DATA_CALC_Y, _AT_CHECK_CALC)
 359         (AT_CHECK_CALC): New macros.
 360         Use these macros to test bison with options `', `--raw',
 361         `--debug', `--yacc', `--yacc --debug'.
 362
 363 2000-09-19  Akim Demaille  <akim@epita.fr>
 364
 365         * src/output.c: Formatting changes.
 366         * src/machine.h: Remove, leaving its contents in...
 367         * src/system.h: here.
 368         Include stdio.h.
 369         Adjust all dependencies on stdio.h and machine.h.
 370         * src/getargs.h: New file.
 371         Let all `extern' declarations about getargs.c be replaced with
 372         inclusion of `getargs.h'.
 373         * src/Makefile.am (noinst_HEADERS): Adjust.
 374
 375         * tests/calc.m4 (yyin): Be initialized in main, not on the global
 376         scope.
 377         (yyerror): Returns void, not int.
 378         * doc/bison.texinfo: Formatting changes.
 379
 380 2000-09-19  Akim Demaille  <akim@epita.fr>
 381
 382         * tests/calc.m4 (calc.y): Do not assign to stdin, as it's not
 383         portable.
 384
 385 2000-09-18  Akim Demaille  <akim@epita.fr>

 506
 507         * src/Makefile.am (bison.simple): Fix the awk program: quote only

 534         copy_comment.  Removed now unused `match', `ended',
 535         `cplus_comment'.
 536         (copy_comment, copy_string): Moved, to be visible from

 563
 564         Change the handling of @s so that they behave exactly like $s.
 565         There is now a pseudo variable @$ (readble and writable), location
 566         of the lhs of the rule (by default ranging from the location of
 567         the first symbol of the rhs, to the location of the last symbol,
 568         or, if the rhs is empty, YYLLOC).
 569

 571         yyval.
 572         (yyparse): When providing a default semantic action, provide a
 573         default location action.
 574         (after the $): No longer change `*YYLSP', just stack YYLOC the
 575         same way you stack YYVAL.
 576         * src/reader.c (read_declarations): Use warns.
 577         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
 578         (copy_action, case '@'): Likewise.
 579         Use a standard error message, to save useless work from
 580         translators.
 581
 582 2000-03-17  Akim Demaille  <akim@epita.fr>
 583

 601
 602         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
 603         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
 604         One `#if YYDEBUG' remains, since it uses variables which are
 605         defined only if `YYDEBUG != 0'.
 606
 607 2000-03-16  Akim Demaille  <akim@epita.fr>
 608
 609         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

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

 641         locale files.
 642         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
 643         builddir.
 644         * acinclude.m4: Remove, replaced by the directory m4.
 645         * m4/Makefile.am (EXTRA_DIST): New variable.
 646         * m4/gettext.m4: New file, from the fileutils.

1333         major changes to files.c.
1334         (lex) Retain in the incoming stream a character following
1335         an incorrect '/'.
