ChangeLog

   1 2000-10-04  Akim Demaille  <akim@epita.fr>
   2
   3         When a literal string is used to define two different tokens,
   4         `bison -v' segfaults.
   5         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
   6
   7         * tests/regression.m4: New file.
   8         Include the core of the sample provided by Piotr Gackiewicz.
   9         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
  10         properly.
  11
  12 2000-10-04  Akim Demaille  <akim@epita.fr>
  13
  14         * src/reader.c (parse_expect_decl): Keep `count' within the size
  15         of `buffer'.
  16         From Neil Booth.
  17
  18 2000-10-02  Paul Eggert  <eggert@twinsun.com>
  19
  20         * bison.s1 (yyparse): Assign the default value
  21         unconditionally, to avoid a GCC warning and make the parser a
  22         tad smaller.
  23
  24 2000-10-02  Akim Demaille  <akim@epita.fr>
  25
  26         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
  27         options.
  28
  29 2000-10-02  Akim Demaille  <akim@epita.fr>
  30
  31         * src/derives.c, src/print.c, src/reduce.c: To ease the
  32         translation, move some `\n' out of the translated strings.
  33
  34 2000-10-02  Akim Demaille  <akim@epita.fr>
  35
  36         The location tracking mechanism is precious for parse error
  37         messages.  Nevertheless, it is enabled only when `@n' is used in
  38         the grammar, which is a different issue (you can use it in error
  39         message, but not in the grammar per se).  Therefore, there should
  40         be another means to enable it.
  41
  42         * src/getargs.c (getargs): Support `--locations'.
  43         (usage): Report it.
  44         * src/getargs.h (locationsflag): Export it.
  45         * src/lex.c (percent_table): Support `%locations'.
  46         * src/reader.c (yylsp_needed): Remove this variable, now replaced
  47         with `locationsflag'.
  48         * doc/bison.texinfo: Document `--locations' and `%locations'.
  49         Sort the options.
  50         * tests/calc.m4: Test it.
  51
  52         For regularity of the names, replace each
  53         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
  54         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
  55         In addition replace each `flag' with `_flag'.
  56
  57 2000-10-02  Akim Demaille  <akim@epita.fr>
  58
  59         Also test parse error messages, including with YYERROR_VERBOSE.
  60
  61         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
  62         associative).
  63         Use it to check the computations.
  64         Use it to check `nonassoc' is honored.
  65         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
  66         `--yyerror-verbose'.
  67         (_AT_CHECK_CALC): Adjust to this option.
  68         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
  69
  70 2000-10-02  Akim Demaille  <akim@epita.fr>
  71
  72         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
  73         the latter demonstrates a flaw in the handling of non debugging
  74         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
  75         was used in order to simplify:
  76
  77         #if YYDEBUG
  78         if (yydebug)
  79         {
  80         ...
  81         }
  82         #endif
  83
  84         into
  85
  86         if (yydebug)
  87         {
  88         ...
  89         }
  90
  91         unfortunately this leads to a CPP conflict when
  92         `--name-prefix=foo' is used since it produces `#define yydebug
  93         foodebug'.
  94
  95         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
  96         (YYDPRINTF): New macro.
  97         Spread its use.
  98         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
  99         the bison options.
 100         Also test `--verbose', `--defines' and `--name-prefix'.
 101
 102 2000-10-02  Akim Demaille  <akim@epita.fr>
 103
 104         Improve the readability of the produced parsers.
 105
 106         * src/bison.s1: Formatting changes.
 107         Improve the comment related to the `$' mark.
 108         (yydefault): Don't fall through to `yyresume': `goto' there.
 109         * src/output.c (output_parser): When the `$' is met, skip the end
 110         of its line.
 111         New variable, `number_of_dollar_signs', to check there's exactly
 112         one `$' in the parser skeleton.
 113
 114 2000-10-02  Akim Demaille  <akim@epita.fr>
 115
 116         * lib/xstrdup.c: New file, from the fileutils.
 117         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 118         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 119         instead of strlen + xmalloc + strcpy.
 120         * src/symtab.c (copys): Remove, use xstrdup instead.
 121
 122 2000-10-02  Akim Demaille  <akim@epita.fr>
 123
 124         * src/gram.h (associativity): New enum type which replaces the
 125         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 126         `right_assoc', `left_assoc' and `non_assoc'.
 127         Adjust all dependencies.
 128         * src/reader.c: Formatting changes.
 129         (LTYPESTR): Don't define it, use it as a literal in
 130         `reader_output_yylsp'.
 131         * src/symtab.h (symbol_class): New enum type which replaces the
 132         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 133         `sunknown', `stoken and `snterm'.
 134
 135 2000-10-02  Akim Demaille  <akim@epita.fr>
 136
 137         * src/getargs.c (fixed_outfiles): Rename as...
 138         (yaccflag): for consistency and accuracy.
 139         Adjust dependencies.
 140
 141 2000-10-02  Akim Demaille  <akim@epita.fr>
 142
 143         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 144         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 145         difficult and introduced a lot of core dump.  It turns out that
 146         Bison used an implementation of `xmalloc' based on `calloc', and
 147         at various places it does depend upon the initialization to 0.  I
 148         have not tried to isolate the pertinent places, and all the former
 149         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 150         someone should address this issue.
 151
 152         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 153         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 154         files.
 155         Adjust dependencies.
 156         * src/warshall.h: New file.
 157         Propagate.
 158
 159 2000-10-02  Akim Demaille  <akim@epita.fr>
 160
 161         Various anti-`extern in *.c' changes.
 162
 163         * src/system.h: Include `assert.h'.
 164
 165 2000-10-02  Akim Demaille  <akim@epita.fr>
 166
 167         * src/state.h (nstates, final_state, first_state, first_shift)
 168         (first_reduction): Move their exportation from here...
 169         * src/LR0.h: to here.
 170         Adjust dependencies.
 171         * src/getargs.c (statisticsflag): New variable.

 173         Adjust dependencies.
 174
 175         Remove a lot of now useless `extern' statements in most files.
 176
 177 2000-10-02  Akim Demaille  <akim@epita.fr>
 178
 179         * src/LR0.h: New file.
 180         Propagate its use.

 189         Adjust dependencies.
 190
 191 2000-10-02  Akim Demaille  <akim@epita.fr>

 217         (tryopen, tryclose, openfiles): Rename as...
 218         (xfopen, xfclose, open_files): this.
 219         (stringappend): static.
 220         * src/files.h: Complete the list of exported symbols.

 244
 245 2000-10-02  Akim Demaille  <akim@epita.fr>
 246
 247         * src/output.c (token_actions): Introduce a temporary array,
 248         YYDEFACT, that makes it possible for this function to use
 249         output_short_table.
 250
 251 2000-10-02  Akim Demaille  <akim@epita.fr>
 252
 253         `user_toknums' is output as a `short[]' in `output.c', while it is
 254         defined as a `int[]' in `reader.c'.  For consistency with the
 255         other output tables, `user_toknums' is now defined as a table of
 256         shorts.
 257
 258         * src/reader.c (user_toknums): Be a short table instead of an int
 259         table.
 260         Adjust dependencies.
 261
 262         Factor the short table outputs.
 263
 264         * src/output.c (output_short_table): New function.
 265         * src/output.c (output_gram, output_stos, output_rule_data)

 267
 268 2000-10-02  Akim Demaille  <akim@epita.fr>
 269
 270         * src/output.c (output): Topological sort of the functions, in
 271         order to get rid of the `static' prototypes.
 272         No longer use `register'.
 273         * src/output.h: New file.
 274         Propagate its inclusion in files explicitly prototyping functions
 275         from output.c.
 276
 277 2000-09-21  Akim Demaille  <akim@epita.fr>
 278
 279         * src/atgeneral.m4: Update from Autoconf.
 280
 281 2000-09-21  Akim Demaille  <akim@epita.fr>
 282
 283         * src/closure.h: New file.
 284         * src/closure.c: Formatting changes, topological sort over the
 285         functions, use of closure.h.
 286         (initialize_closure, finalize_closure):  Rename as...
 287         (new_closure, free_closure): these.  Adjust dependencies.
 288         * src/LR0.c: Formatting changes, topological sort, use of
 289         cloture.h.
 290         (initialize_states): Rename as...
 291         (new_states): this.
 292         * src/Makefile.am (noinst_HEADERS): Adjust.
 293
 294 2000-09-20  Akim Demaille  <akim@epita.fr>
 295
 296         * src/acconfig.h: Don't protect config.h against multiple
 297         inclusion.
 298         Don't define PARAMS.
 299         * src/system.h: Define PARAMS.
 300         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 301         purpose of config.h.  system.h must not try to fix wrong
 302         definitions in config.h.
 303
 304 2000-09-20  Akim Demaille  <akim@epita.fr>
 305

 314         * tests/calc.m4 (_AT_DATA_CALC_Y, AT_DATA_CALC_Y, _AT_CHECK_CALC)
 315         (AT_CHECK_CALC): New macros.
 316         Use these macros to test bison with options `', `--raw',
 317         `--debug', `--yacc', `--yacc --debug'.
 318
 319 2000-09-19  Akim Demaille  <akim@epita.fr>
 320
 321         * src/output.c: Formatting changes.
 322         * src/machine.h: Remove, leaving its contents in...
 323         * src/system.h: here.
 324         Include stdio.h.
 325         Adjust all dependencies on stdio.h and machine.h.
 326         * src/getargs.h: New file.
 327         Let all `extern' declarations about getargs.c be replaced with
 328         inclusion of `getargs.h'.
 329         * src/Makefile.am (noinst_HEADERS): Adjust.
 330
 331         * tests/calc.m4 (yyin): Be initialized in main, not on the global

 337
 338         * tests/calc.m4 (calc.y): Do not assign to stdin, as it's not
 339         portable.
 340
 341 2000-09-18  Akim Demaille  <akim@epita.fr>
 342
 343         * configure.in: Append WARNING_CFLAGS to CFLAGS.
 344         * src/Makefile.am (INCLUDES): Don't.
 345         Be ready to fetch headers in lib/.
 346
 347 2000-09-18  Akim Demaille  <akim@epita.fr>
 348
 349         * doc/bison.texinfo: Update the copyright.
 350         ANSIfy and GNUify the examples.
 351         Remove the old menu.
 352
 353 2000-09-18  Akim Demaille  <akim@epita.fr>
 354
 355         First set of tests: use the `calc' example from the documentation.
 356
 357         * src/bison.s1 (yyparse): Condition the code using `yytname' which
 358         is defined only when YYDEBUG is.
 359         * m4/atconfig.m4 (AT_CONFIG): Adjust to Autoconf 2.13.
 360         * src/files.c (tryopen, tryclose): Formatting changes.

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

 519
 520         Change the handling of @s so that they behave exactly like $s.
 521         There is now a pseudo variable @$ (readble and writable), location
 522         of the lhs of the rule (by default ranging from the location of
 523         the first symbol of the rhs, to the location of the last symbol,
 524         or, if the rhs is empty, YYLLOC).
 525

 527         yyval.
 528         (yyparse): When providing a default semantic action, provide a
 529         default location action.
 530         (after the $): No longer change `*YYLSP', just stack YYLOC the
 531         same way you stack YYVAL.
 532         * src/reader.c (read_declarations): Use warns.
 533         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
 534         (copy_action, case '@'): Likewise.
 535         Use a standard error message, to save useless work from
 536         translators.
 537
 538 2000-03-17  Akim Demaille  <akim@epita.fr>

 557
 558         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
 559         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
 560         One `#if YYDEBUG' remains, since it uses variables which are
 561         defined only if `YYDEBUG != 0'.
 562
 563 2000-03-16  Akim Demaille  <akim@epita.fr>
 564
 565         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

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

 597         locale files.
 598         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
 599         builddir.
 600         * acinclude.m4: Remove, replaced by the directory m4.
 601         * m4/Makefile.am (EXTRA_DIST): New variable.

1248         (get_type, packsymbols):  Revised most error messages.
1249         Changed `fatal' to `warnxxx' to avoid aborting for error.
1250         Revised and use multiple warnxxx functions to avoid using VARARGS1.

1268         (fatals): Updated to not use VARARGS1.
1269         (printable_version, int_to_string, warn, warni, warns, warnss)
1270         (warnsss): New error reporting functions.  Avoid abort for error.

1288         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
1289         major changes to files.c.
1290         (lex) Retain in the incoming stream a character following
1291         an incorrect '/'.
1292         (skip_white_space, lex):  Revised most error messages
1293         and changed fatal to warn to avoid aborting.
