  24
  25         When a literal string is used to define two different tokens,
  26         `bison -v' segfaults.

  38         From Neil Booth.
  39
  40 2000-10-02  Paul Eggert  <eggert@twinsun.com>
  41
  42         * bison.s1 (yyparse): Assign the default value
  43         unconditionally, to avoid a GCC warning and make the parser a
  44         tad smaller.
  45
  46 2000-10-02  Akim Demaille  <akim@epita.fr>
  47
  48         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
  49         options.
  50
  51 2000-10-02  Akim Demaille  <akim@epita.fr>
  52
  53         * src/derives.c, src/print.c, src/reduce.c: To ease the
  54         translation, move some `\n' out of the translated strings.
  55
  56 2000-10-02  Akim Demaille  <akim@epita.fr>
  57
  58         The location tracking mechanism is precious for parse error
  59         messages.  Nevertheless, it is enabled only when `@n' is used in
  60         the grammar, which is a different issue (you can use it in error
  61         message, but not in the grammar per se).  Therefore, there should
  62         be another means to enable it.
  63
  64         * src/getargs.c (getargs): Support `--locations'.
  65         (usage): Report it.
  66         * src/getargs.h (locationsflag): Export it.
  67         * src/lex.c (percent_table): Support `%locations'.
  68         * src/reader.c (yylsp_needed): Remove this variable, now replaced
  69         with `locationsflag'.
  70         * doc/bison.texinfo: Document `--locations' and `%locations'.
  71         Sort the options.
  72         * tests/calc.m4: Test it.
  73
  74         For regularity of the names, replace each
  75         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
  76         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
  77         In addition replace each `flag' with `_flag'.
  78
  79 2000-10-02  Akim Demaille  <akim@epita.fr>
  80
  81         Also test parse error messages, including with YYERROR_VERBOSE.
  82
  83         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
  84         associative).
  85         Use it to check the computations.
  86         Use it to check `nonassoc' is honored.
  87         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
  88         `--yyerror-verbose'.
  89         (_AT_CHECK_CALC): Adjust to this option.
  90         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
  91
  92 2000-10-02  Akim Demaille  <akim@epita.fr>
  93
  94         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
  95         the latter demonstrates a flaw in the handling of non debugging
  96         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
  97         was used in order to simplify:
  98
  99         #if YYDEBUG
 100         if (yydebug)
 101         {
 102         ...
 103         }
 104         #endif
 105
 106         into
 107
 108         if (yydebug)
 109         {
 110         ...
 111         }
 112
 113         unfortunately this leads to a CPP conflict when
 114         `--name-prefix=foo' is used since it produces `#define yydebug
 115         foodebug'.
 116
 117         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 118         (YYDPRINTF): New macro.
 119         Spread its use.
 120         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 121         the bison options.
 122         Also test `--verbose', `--defines' and `--name-prefix'.
 123
 124 2000-10-02  Akim Demaille  <akim@epita.fr>
 125
 126         Improve the readability of the produced parsers.
 127
 128         * src/bison.s1: Formatting changes.
 129         Improve the comment related to the `$' mark.
 130         (yydefault): Don't fall through to `yyresume': `goto' there.
 131         * src/output.c (output_parser): When the `$' is met, skip the end
 132         of its line.
 133         New variable, `number_of_dollar_signs', to check there's exactly
 134         one `$' in the parser skeleton.
 135
 136 2000-10-02  Akim Demaille  <akim@epita.fr>
 137
 138         * lib/xstrdup.c: New file, from the fileutils.
 139         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 140         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 141         instead of strlen + xmalloc + strcpy.
 142         * src/symtab.c (copys): Remove, use xstrdup instead.
 143
 144 2000-10-02  Akim Demaille  <akim@epita.fr>
 145
 146         * src/gram.h (associativity): New enum type which replaces the
 147         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 148         `right_assoc', `left_assoc' and `non_assoc'.
 149         Adjust all dependencies.
 150         * src/reader.c: Formatting changes.
 151         (LTYPESTR): Don't define it, use it as a literal in
 152         `reader_output_yylsp'.
 153         * src/symtab.h (symbol_class): New enum type which replaces the
 154         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 155         `sunknown', `stoken and `snterm'.
 156
 157 2000-10-02  Akim Demaille  <akim@epita.fr>
 158
 159         * src/getargs.c (fixed_outfiles): Rename as...
 160         (yaccflag): for consistency and accuracy.
 161         Adjust dependencies.
 162
 163 2000-10-02  Akim Demaille  <akim@epita.fr>
 164
 165         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 166         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 167         difficult and introduced a lot of core dump.  It turns out that
 168         Bison used an implementation of `xmalloc' based on `calloc', and
 169         at various places it does depend upon the initialization to 0.  I
 170         have not tried to isolate the pertinent places, and all the former
 171         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 172         someone should address this issue.
 173
 174         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 175         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 176         files.
 177         Adjust dependencies.
 178         * src/warshall.h: New file.
 179         Propagate.
 180
 181 2000-10-02  Akim Demaille  <akim@epita.fr>
 182
 183         Various anti-`extern in *.c' changes.
 184
 185         * src/system.h: Include `assert.h'.
 186
 187 2000-10-02  Akim Demaille  <akim@epita.fr>
 188
 189         * src/state.h (nstates, final_state, first_state, first_shift)
 190         (first_reduction): Move their exportation from here...
 191         * src/LR0.h: to here.
 192         Adjust dependencies.
 193         * src/getargs.c (statisticsflag): New variable.

 200
 201         * src/LR0.h: New file.
 202         Propagate its use.

 208         * src/print.c: Formatting and ordering changes.
 209         (verbose, terse): Replace with...

 211         Adjust dependencies.
 212
 213 2000-10-02  Akim Demaille  <akim@epita.fr>

 239         (tryopen, tryclose, openfiles): Rename as...
 240         (xfopen, xfclose, open_files): this.
 241         (stringappend): static.
 242         * src/files.h: Complete the list of exported symbols.
 243         Propagate its use.
 244
 245 2000-10-02  Akim Demaille  <akim@epita.fr>
 246
 247         * src/reader.h: New file.
 248         Propagate its use instead of tedious list of `extern' and

 264         Propagate its inclusion instead of prototypes and `extern'.
 265         * src/lalr.c: Formatting changes, topological sorting etc.
 266
 267 2000-10-02  Akim Demaille  <akim@epita.fr>
 268
 269         * src/output.c (token_actions): Introduce a temporary array,
 270         YYDEFACT, that makes it possible for this function to use
 271         output_short_table.
 272
 273 2000-10-02  Akim Demaille  <akim@epita.fr>
 274
 275         `user_toknums' is output as a `short[]' in `output.c', while it is
 276         defined as a `int[]' in `reader.c'.  For consistency with the
 277         other output tables, `user_toknums' is now defined as a table of
 278         shorts.
 279
 280         * src/reader.c (user_toknums): Be a short table instead of an int
 281         table.

 283
 284         Factor the short table outputs.
 285
 286         * src/output.c (output_short_table): New function.
 287         * src/output.c (output_gram, output_stos, output_rule_data)

 289
 290 2000-10-02  Akim Demaille  <akim@epita.fr>
 291
 292         * src/output.c (output): Topological sort of the functions, in
 293         order to get rid of the `static' prototypes.
 294         No longer use `register'.
 295         * src/output.h: New file.
 296         Propagate its inclusion in files explicitly prototyping functions
 297         from output.c.
 298
 299 2000-09-21  Akim Demaille  <akim@epita.fr>
 300
 301         * src/atgeneral.m4: Update from Autoconf.
 302
 303 2000-09-21  Akim Demaille  <akim@epita.fr>
 304
 305         * src/closure.h: New file.
 306         * src/closure.c: Formatting changes, topological sort over the
 307         functions, use of closure.h.
 308         (initialize_closure, finalize_closure):  Rename as...
 309         (new_closure, free_closure): these.  Adjust dependencies.
 310         * src/LR0.c: Formatting changes, topological sort, use of
 311         cloture.h.
 312         (initialize_states): Rename as...
 313         (new_states): this.
 314         * src/Makefile.am (noinst_HEADERS): Adjust.
 315
 316 2000-09-20  Akim Demaille  <akim@epita.fr>
 317
 318         * src/acconfig.h: Don't protect config.h against multiple
 319         inclusion.
 320         Don't define PARAMS.
 321         * src/system.h: Define PARAMS.
 322         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 323         purpose of config.h.  system.h must not try to fix wrong
 324         definitions in config.h.
 325
 326 2000-09-20  Akim Demaille  <akim@epita.fr>
 327

 336         * tests/calc.m4 (_AT_DATA_CALC_Y, AT_DATA_CALC_Y, _AT_CHECK_CALC)
 337         (AT_CHECK_CALC): New macros.
 338         Use these macros to test bison with options `', `--raw',
 339         `--debug', `--yacc', `--yacc --debug'.
 340
 341 2000-09-19  Akim Demaille  <akim@epita.fr>
 342
 343         * src/output.c: Formatting changes.
 344         * src/machine.h: Remove, leaving its contents in...
 345         * src/system.h: here.
 346         Include stdio.h.
 347         Adjust all dependencies on stdio.h and machine.h.
 348         * src/getargs.h: New file.
 349         Let all `extern' declarations about getargs.c be replaced with
 350         inclusion of `getargs.h'.
 351         * src/Makefile.am (noinst_HEADERS): Adjust.
 352
 353         * tests/calc.m4 (yyin): Be initialized in main, not on the global

 360         * tests/calc.m4 (calc.y): Do not assign to stdin, as it's not
 361         portable.
 362
 363 2000-09-18  Akim Demaille  <akim@epita.fr>
 364
 365         * configure.in: Append WARNING_CFLAGS to CFLAGS.
 366         * src/Makefile.am (INCLUDES): Don't.
 367         Be ready to fetch headers in lib/.
 368
 369 2000-09-18  Akim Demaille  <akim@epita.fr>
 370
 371         * doc/bison.texinfo: Update the copyright.
 372         ANSIfy and GNUify the examples.
 373         Remove the old menu.
 374
 375 2000-09-18  Akim Demaille  <akim@epita.fr>
 376
 377         First set of tests: use the `calc' example from the documentation.
 378
 379         * src/bison.s1 (yyparse): Condition the code using `yytname' which
 380         is defined only when YYDEBUG is.
 381         * m4/atconfig.m4 (AT_CONFIG): Adjust to Autoconf 2.13.
 382         * src/files.c (tryopen, tryclose): Formatting changes.

 484
 485         * src/Makefile.am (bison.simple): Fix the awk program: quote only
 486         the file name, not the whole `#line LINE FILE'.

 512         copy_comment.  Removed now unused `match', `ended',
 513         `cplus_comment'.
 514         (copy_comment, copy_string): Moved, to be visible from

 541
 542         Change the handling of @s so that they behave exactly like $s.
 543         There is now a pseudo variable @$ (readble and writable), location
 544         of the lhs of the rule (by default ranging from the location of
 545         the first symbol of the rhs, to the location of the last symbol,
 546         or, if the rhs is empty, YYLLOC).
 547
 548         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
 549         yyval.
 550         (yyparse): When providing a default semantic action, provide a
 551         default location action.
 552         (after the $): No longer change `*YYLSP', just stack YYLOC the
 553         same way you stack YYVAL.
 554         * src/reader.c (read_declarations): Use warns.
 555         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
 556         (copy_action, case '@'): Likewise.
 557         Use a standard error message, to save useless work from
 558         translators.
 559
 560 2000-03-17  Akim Demaille  <akim@epita.fr>
 561

 579
 580         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
 581         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
 582         One `#if YYDEBUG' remains, since it uses variables which are
 583         defined only if `YYDEBUG != 0'.
 584
 585 2000-03-16  Akim Demaille  <akim@epita.fr>
 586
 587         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

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

 619         locale files.
 620         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
 621         builddir.
 622         * acinclude.m4: Remove, replaced by the directory m4.
 623         * m4/Makefile.am (EXTRA_DIST): New variable.
 624         * m4/gettext.m4: New file, from the fileutils.

 675
 676         * src/getargs.c, src/Makefile.am, src/reader.c, src/version.c:

1310         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
1311         major changes to files.c.
1312         (lex) Retain in the incoming stream a character following
1313         an incorrect '/'.
1314         (skip_white_space, lex):  Revised most error messages
