ChangeLog

   1 2000-12-12  Akim Demaille  <akim@epita.fr>
   2
   3         * src/reader.c (copy_definition, parse_union_decl, copy_action)
   4         (copy_guard): Quote the file names.
   5         Reported by Laurent Mascherpa.
   6
   7 2000-12-12  Akim Demaille  <akim@epita.fr>
   8
   9         * src/output.c (output_headers, output_program, output): Be sure
  10         to escape special characters when outputting filenames.
  11         (ACTSTR_PROLOGUE, ACTSTR_EPILOGUE): Remove.
  12         (output_headers): Don't depend on them, Use ACTSTR.
  13
  14 2000-11-17  Akim Demaille  <akim@epita.fr>
  15
  16         * lib/obstack.h: Formatting changes.
  17         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
  18         prevents type checking.
  19         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
  20         cast the value to (void *): assigning a `foo *' to a `void *'
  21         variable is valid.
  22         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
  23         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
  24         append characters.
  25

  32
  33 2000-11-17  Akim Demaille  <akim@epita.fr>

  44
  45 2000-11-17  Akim Demaille  <akim@epita.fr>
  46
  47         * acconfig.h: Remove, no longer used.

  54
  55         * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
  56         defining.
  57         * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
  58
  59 2000-11-07  Akim Demaille  <akim@epita.fr>
  60
  61         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
  62         Merge in a single CPP if/else.
  63
  64 2000-11-07  Akim Demaille  <akim@epita.fr>
  65

  69         Qualify it `const'.
  70         (obstack_copy, obstack_copy0): Rename the second argument as
  71         `address' for consistency.  Qualify it `const'.
  72         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
  73         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
  74         `const' their input argument (`data' or `address').
  75         Adjust the corresponding macros to include `const' in casts.
  76

  81         Adjust dependencies.
  82
  83 2000-11-03  Akim Demaille  <akim@epita.fr>
  84
  85         For some reason, this was not applied.
  86
  87         * src/files.c [VMS]: No longer include `ssdef.h', no longer define
  88         `unlink': it's no longer used.

  91
  92         * src/files.c (skeleton_find): New function, eved out of...

  94
  95 2000-11-03  Akim Demaille  <akim@epita.fr>

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

 132         * src/files.c (fattrs): Remove.
 133         (attrs_obstack): New.

 150
 151 2000-10-16  Akim Demaille  <akim@epita.fr>
 152

 174 2000-10-16  Akim Demaille  <akim@epita.fr>
 175
 176         * src/reader.c (copy_comment2): Expect the input stream to be on
 177         the `/' which is suspected to open a comment, instead of being

 179         (copy_comment, copy_definition, parse_union_decl, copy_action)
 180         (copy_guard): Adjust.

 205
 206         * doc/bison.texinfo: Various typos spotted by Neil Booth.
 207
 208 2000-10-04  Akim Demaille  <akim@epita.fr>
 209
 210         When a literal string is used to define two different tokens,
 211         `bison -v' segfaults.
 212         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 213
 214         * tests/regression.m4: New file.
 215         Include the core of the sample provided by Piotr Gackiewicz.
 216         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
 217         properly.
 218
 219 2000-10-04  Akim Demaille  <akim@epita.fr>
 220
 221         * src/reader.c (parse_expect_decl): Keep `count' within the size
 222         of `buffer'.
 223         From Neil Booth.
 224
 225 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 226
 227         * bison.s1 (yyparse): Assign the default value
 228         unconditionally, to avoid a GCC warning and make the parser a
 229         tad smaller.
 230
 231 2000-10-02  Akim Demaille  <akim@epita.fr>
 232
 233         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
 234         options.
 235
 236 2000-10-02  Akim Demaille  <akim@epita.fr>
 237
 238         * src/derives.c, src/print.c, src/reduce.c: To ease the
 239         translation, move some `\n' out of the translated strings.
 240
 241 2000-10-02  Akim Demaille  <akim@epita.fr>
 242
 243         The location tracking mechanism is precious for parse error
 244         messages.  Nevertheless, it is enabled only when `@n' is used in
 245         the grammar, which is a different issue (you can use it in error
 246         message, but not in the grammar per se).  Therefore, there should
 247         be another means to enable it.
 248
 249         * src/getargs.c (getargs): Support `--locations'.
 250         (usage): Report it.
 251         * src/getargs.h (locationsflag): Export it.
 252         * src/lex.c (percent_table): Support `%locations'.
 253         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 254         with `locationsflag'.
 255         * doc/bison.texinfo: Document `--locations' and `%locations'.
 256         Sort the options.
 257         * tests/calc.m4: Test it.
 258
 259         For regularity of the names, replace each
 260         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 261         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 262         In addition replace each `flag' with `_flag'.
 263
 264 2000-10-02  Akim Demaille  <akim@epita.fr>
 265
 266         Also test parse error messages, including with YYERROR_VERBOSE.
 267
 268         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 269         associative).
 270         Use it to check the computations.
 271         Use it to check `nonassoc' is honored.
 272         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 273         `--yyerror-verbose'.
 274         (_AT_CHECK_CALC): Adjust to this option.
 275         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 276
 277 2000-10-02  Akim Demaille  <akim@epita.fr>
 278
 279         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 280         the latter demonstrates a flaw in the handling of non debugging
 281         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 282         was used in order to simplify:
 283
 284         #if YYDEBUG
 285         if (yydebug)
 286         {
 287         ...
 288         }
 289         #endif
 290
 291         into
 292
 293         if (yydebug)
 294         {
 295         ...
 296         }
 297
 298         unfortunately this leads to a CPP conflict when
 299         `--name-prefix=foo' is used since it produces `#define yydebug
 300         foodebug'.
 301
 302         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 303         (YYDPRINTF): New macro.
 304         Spread its use.
 305         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 306         the bison options.
 307         Also test `--verbose', `--defines' and `--name-prefix'.
 308
 309 2000-10-02  Akim Demaille  <akim@epita.fr>
 310
 311         Improve the readability of the produced parsers.
 312
 313         * src/bison.s1: Formatting changes.
 314         Improve the comment related to the `$' mark.
 315         (yydefault): Don't fall through to `yyresume': `goto' there.
 316         * src/output.c (output_parser): When the `$' is met, skip the end
 317         of its line.
 318         New variable, `number_of_dollar_signs', to check there's exactly
 319         one `$' in the parser skeleton.
 320
 321 2000-10-02  Akim Demaille  <akim@epita.fr>
 322
 323         * lib/xstrdup.c: New file, from the fileutils.
 324         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 325         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 326         instead of strlen + xmalloc + strcpy.
 327         * src/symtab.c (copys): Remove, use xstrdup instead.
 328
 329 2000-10-02  Akim Demaille  <akim@epita.fr>
 330
 331         * src/gram.h (associativity): New enum type which replaces the
 332         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 333         `right_assoc', `left_assoc' and `non_assoc'.
 334         Adjust all dependencies.
 335         * src/reader.c: Formatting changes.
 336         (LTYPESTR): Don't define it, use it as a literal in
 337         `reader_output_yylsp'.
 338         * src/symtab.h (symbol_class): New enum type which replaces the
 339         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 340         `sunknown', `stoken and `snterm'.
 341
 342 2000-10-02  Akim Demaille  <akim@epita.fr>
 343
 344         * src/getargs.c (fixed_outfiles): Rename as...
 345         (yaccflag): for consistency and accuracy.
 346         Adjust dependencies.
 347
 348 2000-10-02  Akim Demaille  <akim@epita.fr>
 349
 350         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 351         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 352         difficult and introduced a lot of core dump.  It turns out that
 353         Bison used an implementation of `xmalloc' based on `calloc', and
 354         at various places it does depend upon the initialization to 0.  I
 355         have not tried to isolate the pertinent places, and all the former
 356         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 357         someone should address this issue.
 358
 359         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 360         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 361         files.
 362         Adjust dependencies.
 363         * src/warshall.h: New file.
 364         Propagate.
 365
 366 2000-10-02  Akim Demaille  <akim@epita.fr>
 367
 368         Various anti-`extern in *.c' changes.
 369
 370         * src/system.h: Include `assert.h'.
 371
 372 2000-10-02  Akim Demaille  <akim@epita.fr>
 373
 374         * src/state.h (nstates, final_state, first_state, first_shift)
 375         (first_reduction): Move their exportation from here...
 376         * src/LR0.h: to here.

 459
 460         `user_toknums' is output as a `short[]' in `output.c', while it is
 461         defined as a `int[]' in `reader.c'.  For consistency with the
 462         other output tables, `user_toknums' is now defined as a table of
 463         shorts.
 464

 466         table.

 478         order to get rid of the `static' prototypes.

 481         Propagate its inclusion in files explicitly prototyping functions
 482         from output.c.

 504         inclusion.
 505         Don't define PARAMS.
 506         * src/system.h: Define PARAMS.
 507         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 508         purpose of config.h.  system.h must not try to fix wrong
 509         definitions in config.h.

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

 739         * src/reader.c (read_declarations): Use warns.
 740         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

 743         translators.

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