   2
   3         * src/bison.s1 (YYLLOC_DEFAULT): New macro.
   4         Provide a default definition.
   5         Use it when executing the default @ action.
   6         * src/reader.c (reader_output_yylsp): No longer include
   7         `timestamp' and `text' in the default YYLTYPE.
   8
   9 2000-12-12  Akim Demaille  <akim@epita.fr>
  10
  11         * src/reader.c (copy_definition, parse_union_decl, copy_action)
  12         (copy_guard): Quote the file names.
  13         Reported by Laurent Mascherpa.
  14
  15 2000-12-12  Akim Demaille  <akim@epita.fr>
  16
  17         * src/output.c (output_headers, output_program, output): Be sure
  18         to escape special characters when outputting filenames.
  19         (ACTSTR_PROLOGUE, ACTSTR_EPILOGUE): Remove.
  20         (output_headers): Don't depend on them, Use ACTSTR.
  21
  22 2000-11-17  Akim Demaille  <akim@epita.fr>
  23
  24         * lib/obstack.h: Formatting changes.
  25         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
  26         prevents type checking.
  27         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
  28         cast the value to (void *): assigning a `foo *' to a `void *'
  29         variable is valid.
  30         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
  31         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
  32         append characters.

  40
  41 2000-11-17  Akim Demaille  <akim@epita.fr>

  47
  48         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
  49         macros.

  64         defining.
  65         * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
  66
  67 2000-11-07  Akim Demaille  <akim@epita.fr>
  68
  69         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
  70         Merge in a single CPP if/else.
  71
  72 2000-11-07  Akim Demaille  <akim@epita.fr>
  73
  74         * src/output.c (output): Remove useless variables.
  75         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
  76         argument `data' for consistency with the prototypes.
  77         Qualify it `const'.
  78         (obstack_copy, obstack_copy0): Rename the second argument as
  79         `address' for consistency.  Qualify it `const'.
  80         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
  81         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
  82         `const' their input argument (`data' or `address').

  89         Adjust dependencies.
  90
  91 2000-11-03  Akim Demaille  <akim@epita.fr>
  92
  93         For some reason, this was not applied.
  94
  95         * src/files.c [VMS]: No longer include `ssdef.h', no longer define
  96         `unlink': it's no longer used.

  99
 100         * src/files.c (skeleton_find): New function, eved out of...

 106
 107         * src/files.c (obstack_save): New function.
 108         (done): Rename as...
 109         (output_files): this.
 110         Use `obstack_save'.
 111         * src/main.c (main): Don't use `atexit' to register `done', since
 112         it no longer has to remove tmp files, just call `output_files'
 113         when there are no errors.
 114
 115 2000-11-02  Akim Demaille  <akim@epita.fr>
 116
 117         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 140         * src/files.c (fattrs): Remove.
 141         (attrs_obstack): New.
 142         Adjust all dependencies.

 158
 159 2000-10-16  Akim Demaille  <akim@epita.fr>
 160
 161         * src/output.c (output_short_or_char_table): New function.

 182 2000-10-16  Akim Demaille  <akim@epita.fr>
 183
 184         * src/reader.c (copy_comment2): Expect the input stream to be on
 185         the `/' which is suspected to open a comment, instead of being
 186         called after `//' or `/*' was read.
 187         (copy_comment, copy_definition, parse_union_decl, copy_action)
 188         (copy_guard): Adjust.

 211
 212 2000-10-04  Akim Demaille  <akim@epita.fr>
 213
 214         * doc/bison.texinfo: Various typos spotted by Neil Booth.
 215
 216 2000-10-04  Akim Demaille  <akim@epita.fr>
 217
 218         When a literal string is used to define two different tokens,
 219         `bison -v' segfaults.
 220         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 221
 222         * tests/regression.m4: New file.
 223         Include the core of the sample provided by Piotr Gackiewicz.
 224         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
 225         properly.
 226
 227 2000-10-04  Akim Demaille  <akim@epita.fr>
 228
 229         * src/reader.c (parse_expect_decl): Keep `count' within the size
 230         of `buffer'.
 231         From Neil Booth.
 232
 233 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 234
 235         * bison.s1 (yyparse): Assign the default value
 236         unconditionally, to avoid a GCC warning and make the parser a
 237         tad smaller.
 238
 239 2000-10-02  Akim Demaille  <akim@epita.fr>
 240
 241         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
 242         options.
 243
 244 2000-10-02  Akim Demaille  <akim@epita.fr>
 245
 246         * src/derives.c, src/print.c, src/reduce.c: To ease the
 247         translation, move some `\n' out of the translated strings.
 248
 249 2000-10-02  Akim Demaille  <akim@epita.fr>
 250
 251         The location tracking mechanism is precious for parse error
 252         messages.  Nevertheless, it is enabled only when `@n' is used in
 253         the grammar, which is a different issue (you can use it in error
 254         message, but not in the grammar per se).  Therefore, there should
 255         be another means to enable it.
 256
 257         * src/getargs.c (getargs): Support `--locations'.
 258         (usage): Report it.
 259         * src/getargs.h (locationsflag): Export it.
 260         * src/lex.c (percent_table): Support `%locations'.
 261         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 262         with `locationsflag'.
 263         * doc/bison.texinfo: Document `--locations' and `%locations'.
 264         Sort the options.
 265         * tests/calc.m4: Test it.
 266
 267         For regularity of the names, replace each
 268         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 269         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 270         In addition replace each `flag' with `_flag'.
 271
 272 2000-10-02  Akim Demaille  <akim@epita.fr>
 273
 274         Also test parse error messages, including with YYERROR_VERBOSE.
 275
 276         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 277         associative).
 278         Use it to check the computations.
 279         Use it to check `nonassoc' is honored.
 280         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 281         `--yyerror-verbose'.
 282         (_AT_CHECK_CALC): Adjust to this option.
 283         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 284
 285 2000-10-02  Akim Demaille  <akim@epita.fr>
 286
 287         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 288         the latter demonstrates a flaw in the handling of non debugging
 289         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 290         was used in order to simplify:
 291
 292         #if YYDEBUG
 293         if (yydebug)
 294         {
 295         ...
 296         }
 297         #endif
 298
 299         into
 300
 301         if (yydebug)
 302         {
 303         ...
 304         }
 305
 306         unfortunately this leads to a CPP conflict when
 307         `--name-prefix=foo' is used since it produces `#define yydebug
 308         foodebug'.
 309
 310         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 311         (YYDPRINTF): New macro.
 312         Spread its use.
 313         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 314         the bison options.
 315         Also test `--verbose', `--defines' and `--name-prefix'.
 316
 317 2000-10-02  Akim Demaille  <akim@epita.fr>
 318
 319         Improve the readability of the produced parsers.
 320
 321         * src/bison.s1: Formatting changes.
 322         Improve the comment related to the `$' mark.
 323         (yydefault): Don't fall through to `yyresume': `goto' there.
 324         * src/output.c (output_parser): When the `$' is met, skip the end
 325         of its line.
 326         New variable, `number_of_dollar_signs', to check there's exactly
 327         one `$' in the parser skeleton.
 328
 329 2000-10-02  Akim Demaille  <akim@epita.fr>
 330
 331         * lib/xstrdup.c: New file, from the fileutils.
 332         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 333         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 334         instead of strlen + xmalloc + strcpy.
 335         * src/symtab.c (copys): Remove, use xstrdup instead.
 336
 337 2000-10-02  Akim Demaille  <akim@epita.fr>
 338
 339         * src/gram.h (associativity): New enum type which replaces the
 340         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 341         `right_assoc', `left_assoc' and `non_assoc'.
 342         Adjust all dependencies.
 343         * src/reader.c: Formatting changes.
 344         (LTYPESTR): Don't define it, use it as a literal in
 345         `reader_output_yylsp'.
 346         * src/symtab.h (symbol_class): New enum type which replaces the
 347         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 348         `sunknown', `stoken and `snterm'.
 349
 350 2000-10-02  Akim Demaille  <akim@epita.fr>
 351
 352         * src/getargs.c (fixed_outfiles): Rename as...
 353         (yaccflag): for consistency and accuracy.
 354         Adjust dependencies.
 355
 356 2000-10-02  Akim Demaille  <akim@epita.fr>
 357
 358         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 359         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 360         difficult and introduced a lot of core dump.  It turns out that
 361         Bison used an implementation of `xmalloc' based on `calloc', and
 362         at various places it does depend upon the initialization to 0.  I
 363         have not tried to isolate the pertinent places, and all the former
 364         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 365         someone should address this issue.
 366
 367         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 368         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 369         files.
 370         Adjust dependencies.
 371         * src/warshall.h: New file.
 372         Propagate.
 373
 374 2000-10-02  Akim Demaille  <akim@epita.fr>
 375

 466 2000-10-02  Akim Demaille  <akim@epita.fr>
 467
 468         `user_toknums' is output as a `short[]' in `output.c', while it is
 469         defined as a `int[]' in `reader.c'.  For consistency with the
 470         other output tables, `user_toknums' is now defined as a table of
 471         shorts.
 472
 473         * src/reader.c (user_toknums): Be a short table instead of an int
 474         table.

 484
 485         * src/output.c (output): Topological sort of the functions, in
 486         order to get rid of the `static' prototypes.
 487         No longer use `register'.
 488         * src/output.h: New file.
 489         Propagate its inclusion in files explicitly prototyping functions
 490         from output.c.

 512         inclusion.
 513         Don't define PARAMS.
 514         * src/system.h: Define PARAMS.
 515         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 516         purpose of config.h.  system.h must not try to fix wrong
 517         definitions in config.h.
 518

 736         There is now a pseudo variable @$ (readble and writable), location
 737         of the lhs of the rule (by default ranging from the location of
 738         the first symbol of the rhs, to the location of the last symbol,

 746         same way you stack YYVAL.
 747         * src/reader.c (read_declarations): Use warns.
 748         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

 750         Use a standard error message, to save useless work from
 751         translators.

 773         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to

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

 812         locale files.
 813         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
 814         builddir.
 815         * acinclude.m4: Remove, replaced by the directory m4.
 816         * m4/Makefile.am (EXTRA_DIST): New variable.
