   2
   3         * data/bison.c++: Merge the two generated headers.  Insert a copyright
   4         notice in each output file.
   5
   6 2002-02-28  Akim Demaille  <akim@epita.fr>
   7
   8         * data/bison.c++: Copy the prologue of bison.simple to fetch
   9         useful M4 definitions, such as b4_header_guard.
  10
  11 2002-02-25  Akim Demaille  <akim@epita.fr>
  12
  13         * src/getargs.c (version): Give the name of the authors, and use a
  14         translator friendly scheme for the bgr
  15         copyright notice.
  16
  17 2002-02-25  Akim Demaille  <akim@epita.fr>
  18
  19         * src/output.c (header_output): Remove, now handled completely via
  20         M4.
  21
  22 2002-02-25  Akim Demaille  <akim@epita.fr>
  23
  24         * m4/m4.m4: New, from CVS Autoconf.
  25         * configure.in: Invoke it.
  26         * src/output.c (output_skeleton): Use its result instead of the
  27         hard coded name.
  28
  29 2002-02-25  Akim Demaille  <akim@epita.fr>
  30
  31         * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
  32         Fileutils 4.1.5.
  33         * configure.in: Invoke UTILS_FUNC_MKSTEMP.
  34         * src/output.c (output_skeleton): Use mkstemp to create a real
  35         temporary file.
  36         Move the filling of `skeleton' and its muscle to...
  37         (prepare): here.
  38         (output): Move the definition of the prologue muscle to...
  39         (prepare): here.
  40         * src/system.h (DEFAULT_TMPDIR): New.
  41
  42 2002-02-14  Paul Eggert  <eggert@twinsun.com>
  43
  44         Remove the support for C++ namespace cleanliness; it was
  45         causing more problems than it was curing, since it didn't work
  46         properly on some nonstandard C++ compilers.  This can wait
  47         for a proper C++ parser.
  48
  49         * NEWS: Document this.
  50         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
  51         of C++, as it's treated like C now.
  52         * src/bison.simple (YYSTD): Remove.
  53         (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
  54         Treat C++ just like Standard C instead of trying to support
  55         namespace cleanliness.
  56
  57 2002-02-14  Akim Demaille  <akim@epita.fr>
  58
  59         * tests/regression.at (else): Adjust to Andreas' change.
  60
  61 2002-02-14  Akim Demaille  <akim@epita.fr>
  62
  63         * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
  64
  65 2002-02-13  Andreas Schwab  <schwab@suse.de>
  66
  67         * src/output.c (output_rule_data): Don't output NULL, it might
  68         not be defined yet.
  69
  70 2002-02-11  Robert Anisko  <robert@lrde.epita.fr>
  71
  72         * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
  73         (Copyright notice): Update.
  74
  75 2002-02-11  Akim Demaille  <akim@epita.fr>
  76

  78         nonportable headers.
  79
  80 2002-02-08  Robert Anisko  <robert@lrde.epita.fr>
  81
  82         * data/bison.c++: Correct error recovery.  Make the user able to
  83         initialize the starting location.
  84
  85 2002-02-07  Akim Demaille  <akim@epita.fr>
  86
  87         * tests/input.at: New.
  88
  89 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
  90
  91         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
  92         more consistent when naming methods and variables.  Put preprocessor
  93         directives around tables only needed for debugging.
  94
  95 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
  96
  97         * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
  98         C++ parsers.
  99         (yy::b4_name::parse): Use print_.
 100
 101 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 102
 103         * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
 104
 105 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 106
 107         * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
 108         C++ parsers.

 110
 111 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
 112
 113         * data/bison.c++: Fix m4 quoting in comments.
 114
 115 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
 116
 117         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
 118         not expanded by m4.
 119
 120 2002-02-05  Akim Demaille  <akim@epita.fr>
 121
 122         * data/bison.c++: Adjust to the M4 back end.
 123         More is certainly needed.
 124
 125 2002-02-05  Akim Demaille  <akim@epita.fr>
 126
 127         Give a try to M4 as a back end.
 128
 129         * lib/readpipe.c: New, from wdiff.
 130         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
 131         BISON_HAIRY.
 132         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
 133         specific values.  Now it is m4 that performs the lookup.
 134         * src/parse-skel.y: Remove.
 135         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
 136         * src/output.c (actions_output, guards_output)
 137         (token_definitions_output): No longer keeps track of the output
 138         line number, hence remove the second argument.
 139         (guards_output): Check against the guard member of a rule, not the
 140         action member.
 141         Adjust callers.
 142         (output_skeleton): Don't look for the skeleton location, let m4 do
 143         that.
 144         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
 145         file will be used.
 146         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
 147         (prepare): Given that for the time being changesyntax is not
 148         usable in M4, rename the muscles using `-' to `_'.
 149         Define `defines_flag', `output_parser_name' and `output_header_name'.
 150         * src/output.h (actions_output, guards_output)
 151         (token_definitions_output): Adjust prototypes.
 152         * src/scan-skel.l: Instead of scanning the skeletons, it now
 153         processes the output of m4: `__oline__' and `#output'.
 154         * data/bison.simple: Adjust to be used by M4(sugar).
 155         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
 156         to date.
 157         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
 158         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
 159         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
 160         shamelessly stolen from CVS Autoconf.
 161
 162 2002-02-05  Akim Demaille  <akim@epita.fr>
 163
 164         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
 165         * configure.in: Check for the declarations of free and malloc.
 166         * src/muscle_tab.c: Adjust.
 167
 168 2002-02-05  Akim Demaille  <akim@epita.fr>
 169
 170         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
 171         which have no values.
 172
 173 2002-02-05  Akim Demaille  <akim@epita.fr>
 174
 175         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
 176         * data/: here.
 177
 178 2002-01-29  Paul Eggert  <eggert@twinsun.com>
 179
 180         * src/bison.simple (YYSIZE_T): Do not define merely because
 181         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 182         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 183
 184 2002-01-27  Akim Demaille  <akim@epita.fr>
 185
 186         Fix `%nonassoc and eof'.
 187
 188         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
 189         which were not properly copied!  Replace
 190         memcpy (res->errs, src->errs, src->nerrs);
 191         with
 192         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
 193         !!!
 194         * tests/regression.at (%nonassoc and eof): Adjust to newest
 195         Autotest: `.' is not in the PATH.
 196
 197 2002-01-27  Akim Demaille  <akim@epita.fr>
 198
 199         * tests/sets.at (AT_EXTRACT_SETS): New.
 200         (Nullable): Use it.
 201         (Firsts): New.
 202
 203 2002-01-26  Akim Demaille  <akim@epita.fr>
 204
 205         * tests/actions.at, tests/calc.at, tests/headers.at,
 206         * tests/torture.at: Adjust to the newest Autotest which no longer
 207         forces `.' in the PATH.
 208
 209 2002-01-25  Akim Demaille  <akim@epita.fr>
 210
 211         * tests/regression.at (%nonassoc and eof): New.
 212         Suggested by Robert Anisko.
 213
 214 2002-01-24  Akim Demaille  <akim@epita.fr>
 215
 216         Bison dumps core when trying to complain about broken input files.
 217         Reported by Cris van Pelt.
 218
 219         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
 220         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
 221         into...
 222         (Invalid inputs): Strengthen: exercise parse_percent_token.
 223
 224 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
 225
 226         * src/Makefile.am: Add bison.c++.
 227         * src/bison.c++: New skeleton.
 228
 229 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
 230
 231         * po/it.po: New.
 232
 233 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
 234
 235         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
 236
 237 2002-01-20  Marc Autret  <marc@gnu.org>
 238
 239         * src/files.c (compute_output_file_names): Fix
 240
 241 2002-01-20  Marc Autret  <marc@gnu.org>
 242
 243         * tests/output.at: New test.
 244         * src/files.c (compute_base_names): Don't map extensions when
 245         the YACC flag is set, use defaults.
 246         Reported by Evgeny Stambulchik.
 247
 248 2002-01-20  Marc Autret  <marc@gnu.org>
 249
 250         * src/system.h: Need to define __attribute__ away for non-GCC
 251         compilers as well (i.e. the vendor C compiler).
 252         Suggested by Albert Chin-A-Young.
 253
 254 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
 255
 256         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
 257         canonical definition.
 258         * src/system.h: Use the canonical definition for PARAMS (avoids
 259         a conflict with the macro from lib/hash.h).
 260
 261 2002-01-11  Akim Demaille  <akim@epita.fr>
 262
 263         * configure.in: Use AC_FUNC_STRNLEN.
 264         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
 265
 266 2002-01-09  Akim Demaille  <akim@epita.fr>
 267
 268         * src/files.c, src/files.h (output_infix): New.
 269         (tab_extension): Remove.
 270         (compute_base_names): Compute the former, drop the latter.
 271         * src/output.c (prepare): Insert the muscles `output-infix', and
 272         `output-suffix'.
 273         * src/parse-skel.y (string, string.1): New.
 274         (section.header): Use it.
 275         (section.yacc): Remove.
 276         (prefix): Remove too.
 277         * src/scan-skel.l: Adjust.
 278         * src/bison.simple, src/bison.hairy: Adjust.
 279
 280 2002-01-09  Akim Demaille  <akim@epita.fr>
 281
 282         * configure.in (WERROR_CFLAGS): Compute it.
 283         * src/Makefile.am (CFLAGS): Pass it.
 284         * tests/atlocal.in (CFLAGS): Idem.

 287
 288 2002-01-08  Akim Demaille  <akim@epita.fr>
 289
 290         * src/getargs.c (AS_FILE_NAME): New.
 291         (getargs): Use it to convert DOSish file names.
 292         * src/files.c (base_name): Rename as full_base_name to avoid
 293         clashes with `base_name ()'.
 294         (filename_split): New.
 295         (compute_base_names): N-th rewrite, using filename_split.
 296
 297 2002-01-08  Akim Demaille  <akim@epita.fr>
 298
 299         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
 300         New, stolen from the Fileutils 4.1.
 301         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
 302         * configure.in: Check for the presence of memrchr, and of its

 304
 305 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
 306
 307         * lib/hash.h (__P): Added definition for this macro.
 308         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
 309         BUILT_SOURCES, to ensure they are generated first.
 310         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
 311         %error-verbose to allow bootstrapping with bison 1.30x.
 312
 313 2002-01-06  Akim Demaille  <akim@epita.fr>
 314
 315         * src/reader.c (parse_braces): Don't fetch the next char, the
 316         convention is to fetch on entry.
 317         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
 318         'switch' without a following semicolon.
 319         * tests/regression.at (braces parsing): New.
 320
 321 2002-01-06  Akim Demaille  <akim@epita.fr>
 322
 323         Bison is dead wrong in its RR conflict reports.
 324
 325         * tests/torture.at (GNU Cim Grammar): New.
 326         * src/conflicts.c (count_rr_conflicts): Fix.
 327
 328 2002-01-06  Akim Demaille  <akim@epita.fr>
 329
 330         Creating package.m4 from configure.ac causes too many problems.
 331
 332         * tests/Makefile.am (package.m4): Create it by hand,
 333         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
 334
 335 2002-01-06  Akim Demaille  <akim@epita.fr>
 336
 337         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
 338         skeleton.h.
 339
 340 2002-01-04  Paul Eggert  <eggert@twinsun.com>
 341
 342         * doc/bison.texinfo (Debugging):
 343         Remove YYSTDERR; it's no longer defined or used.
 344         Also, s/cstdio.h/cstdio/.
 345
 346 2002-01-03  Akim Demaille  <akim@epita.fr>
 347
 348         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
 349
 350 2002-01-03  Akim Demaille  <akim@epita.fr>
 351
 352         * src/parse-skel.y (process_skeleton): Don't bind the parser's
 353         tracing code to --trace, wait for a better --trace option, with
 354         args.
 355
 356 2002-01-03  Akim Demaille  <akim@epita.fr>
 357
 358         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
 359         The ISO C++ standard is extremely clear about it: stderr is
 360         considered a macro, not a regular symbol (see table 94 `Header
 361         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
 362         Therefore std:: does not apply to it.  It still does with fprintf.
 363         Also, s/cstdio.h/cstdio/.
 364
 365 2002-01-03  Akim Demaille  <akim@epita.fr>
 366
 367         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
 368         for non system headers.
 369
 370 2002-01-02  Akim Demaille  <akim@epita.fr>
 371
 372         Equip the skeleton chain with location tracking, runtime trace,
 373         pure parser and scanner.
 374
 375         * src/parse-skel.y: Request a pure parser, locations, and prefix
 376         renaming.
 377         (%union): Having several members with the same type does not help
 378         type mismatches, simplify.
 379         (YYPRINT, yyprint): New.
 380         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
 381         (skel_error): this.
 382         Handle locations.
 383         * src/scan-skel.l: Adjust to these changes.
 384         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
 385         (LOCATION_PRINT, skel_control_t): New.
 386
 387 2001-12-30  Akim Demaille  <akim@epita.fr>
 388
 389         * src/parse-skel.y: Get rid of the shift/reduce conflict:
 390         replace `gb' with BLANKS.
 391         * src/scan-skel.l: Adjust.
 392
 393 2001-12-30  Akim Demaille  <akim@epita.fr>
 394
 395         * src/system.h: We don't need nor want bcopy.
 396         Throw away MS-DOS crap: we don't need getpid.
 397         * configure.in: We don't need strndup.  It was even causing
 398         problems: because Flex includes the headers *before* us,
 399         _GNU_SOURCE is not defined by config.h, and therefore strndup was
 400         not visible.
 401         * lib/xstrndup.c: New.
 402         * src/scan-skel.l: Use it.
 403         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
 404         * src/parse-skel.y: Use %directives instead of #defines.
 405
 406 2001-12-30  Akim Demaille  <akim@epita.fr>
 407
 408         * src/skeleton.h: New.
 409         * src/output.c (output_parser, output_master_parser): Remove, dead
 410         code.
 411         * src/output.h (get_lines_number, actions_output, guards_output)
 412         (token_definitions_output): Prototype them.
 413         * src/parse-skel.y: Add the license notice.
 414         Include output.h and skeleton.h.
 415         (process_skeleton): Returns void, and takes a single parameter.
 416         * src/scan-skel.l: Add the license notice.
 417         Include skeleton.h.
 418         Don't use %option yylineno: it seems that then Flex imagines
 419         REJECT has been used, and therefore it won't reallocate its
 420         buffers (which makes no other sense to me than a bug).  It results
 421         in warnings for `unused: yy_flex_realloc'.
 422
 423 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
 424
 425         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 426         (MUSCLE_INSERT_PREFIX): ...to there.
 427         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 428         (MUSCLE_INSERT_PREFIX): Move from here...
 429
 430         * src/bison.hairy: Add a section directive.  Put braces around muscle
 431         names.  This parser skeleton is still broken, but Bison should not
 432         choke on a bad muscle 'syntax'.
 433         * src/bison.simple: Add a section directive.  Put braces around muscle
 434         names.
 435
 436         * src/files.h (strsuffix, stringappend): Add declarations.
 437         (tab_extension): Add declaration.
 438         (short_base_name): Add declaration.
 439
 440         * src/files.c (strsuffix, stringappend): No longer static.  These
 441         functions are used in the skeleton parser.
 442         (tab_extension): New.
 443         (compute_base_names): Use the computations done in this function
 444         to guess if the generated parsers should have '.tab' in their
 445         names.
 446         (short_base_name): No longer static.
 447
 448         * src/output.c (output_skeleton): New.
 449         (output): Disable call to output_master_parser, and give a try to
 450         a new skeleton handling system.
 451         (guards_output, actions_output): No longer static.
 452         (token_definitions_output, get_lines_number): No longer static.
 453
 454         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
 455
 456         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
 457         parse-skel.y.
 458
 459         * src/parse-skel.y: New file.
 460         * src/scan-skel.l: New file.
 461
 462 2001-12-29  Akim Demaille  <akim@epita.fr>
 463
 464         %name-prefix is broken.
 465
 466         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
 467         Adjust all dependencies.
 468         * tests/headers.at (export YYLTYPE): Strengthen this test: use
 469         %name-prefix.
 470
 471         Renaming yylval but not yylloc is not consistent.  Now we do.
 472
 473         * src/bison.simple: Prefix yylloc if used.
 474         * doc/bison.texinfo (Decl Summary): Document that.
 475
 476 2001-12-29  Akim Demaille  <akim@epita.fr>
 477
 478         * doc/bison.texinfo: Promote `%long-directive' over
 479         `%long_directive'.
 480         Remove all references to fixed-output-files, yacc is enough.
 481
 482 2001-12-29  Akim Demaille  <akim@epita.fr>
 483
 484         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
 485         user prologue.  These are defaults.
 486         * tests/actions.at (Mid-rule actions): Make sure the user can
 487         define YYDEBUG and YYERROR_VERBOSE.
 488
 489 2001-12-29  Akim Demaille  <akim@epita.fr>
 490
 491         * src/output.c (header_output): Don't forget to export YYLTYPE and
 492         yylloc.
 493         * tests/headers.at (export YYLTYPE): New, make sure it does.
 494         * tests/regression.at (%union and --defines, Invalid CPP headers):
 495         Move to...
 496         * tests/headers.at: here.
 497
 498 2001-12-29  Akim Demaille  <akim@epita.fr>
 499
 500         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
 501
 502 2001-12-29  Akim Demaille  <akim@epita.fr>
 503
 504         * tests/actions.at (Mid-rule actions): Output on a single line
 505         instead of several.
 506
 507 2001-12-29  Akim Demaille  <akim@epita.fr>
 508
 509         * doc/bison.texinfo: Formatting changes.
 510
 511 2001-12-29  Akim Demaille  <akim@epita.fr>
 512
 513         Don't store the token defs in a muscle, just be ready to output it
 514         on command.  Now possible via `symbols'.  Fixes a memory leak.
 515
 516         * src/output.c (token_definitions_output): New.
 517         (output_parser, header_output): Use it.
 518         * src/reader.c (symbols_save): Remove.
 519
 520 2001-12-29  Akim Demaille  <akim@epita.fr>
 521
 522         * src/bison.simple: Do not provide a default for YYSTYPE and
 523         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
 524         default.
 525
 526 2001-12-29  Akim Demaille  <akim@epita.fr>
 527
 528         Mid-rule actions are simply... ignored!
 529
 530         * src/reader.c (readgram): Be sure to attach mid-rule actions to
 531         the empty-rule associated to the dummy symbol, not to the host
 532         rule.
 533         * tests/actions.at (Mid-rule actions): New.
 534
 535 2001-12-29  Akim Demaille  <akim@epita.fr>
 536
 537         Memory leak.
 538
 539         * src/reader.c (reader): Free grammar.
 540
 541 2001-12-29  Akim Demaille  <akim@epita.fr>
 542
 543         Memory leak.
 544
 545         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
 546         since it allocates it for each state, although only one is needed.
 547         (allocate_storage): Do it here.
 548
 549 2001-12-29  Akim Demaille  <akim@epita.fr>
 550
 551         * src/options.h, src/options.c (create_long_option_table): Rename
 552         as...
 553         (long_option_table_new): this, with a clearer prototype.
 554         (percent_table): Remove, unused,
 555         * src/getargs.c (getargs): Adjust.
 556
 557 2001-12-29  Akim Demaille  <akim@epita.fr>
 558
 559         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
 560         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 561         as states.
 562
 563 2001-12-29  Akim Demaille  <akim@epita.fr>
 564
 565         * src/lalr.c (build_relations): Rename `states' as `states1'.
 566         Sorry, I don't understand exactly what it is, no better name...
 567
 568 2001-12-29  Akim Demaille  <akim@epita.fr>
 569
 570         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 571         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 572         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 573         as rules.
 574
 575 2001-12-29  Akim Demaille  <akim@epita.fr>
 576
 577         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 578         ago.
 579
 580 2001-12-29  Akim Demaille  <akim@epita.fr>
 581
 582         * src/reader.c, src/reader.h (user_toknums): Remove.
 583         Adjust all users to use symbols[i]->user_token_number.
 584
 585 2001-12-29  Akim Demaille  <akim@epita.fr>
 586
 587         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 588         Adjust all users to use symbols[i]->prec or ->assoc.
 589
 590 2001-12-29  Akim Demaille  <akim@epita.fr>
 591
 592         * src/reader.c, src/reader.h (tags): Remove.
 593         Adjust all users to use symbols[i]->tag.
 594
 595 2001-12-29  Akim Demaille  <akim@epita.fr>
 596
 597         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 598         and rule_table.
 599         * src/reader.c (packsymbols): Fill this table.
 600         Drop sprec.
 601         * src/conflicts.c (resolve_sr_conflict): Adjust.
 602         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 603         single table.
 604         Use symbols[i]->tag instead of tags[i].
 605
 606 2001-12-29  Akim Demaille  <akim@epita.fr>
 607
 608         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 609         In addition, put a comment in there, to replace...
 610         * tests/regression.at (%union and C comments): Remove.
 611
 612 2001-12-29  Akim Demaille  <akim@epita.fr>
 613
 614         * tests/regression.at (Web2c Actions): Blindly move the actual
 615         output as expected output.  The contents *seem* right to me, but I
 616         can't pretend reading perfectly parser tables...  Nonetheless, all
 617         the other tests pass correctly, the table look OK, even though the
 618         presence of `$axiom' is to be noted: AFAICS it is useless (but
 619         harmless).
 620
 621 2001-12-29  Akim Demaille  <akim@epita.fr>
 622
 623         * src/reader.c (readgram): Don't add the rule 0 if there were no
 624         rules read.  In other words, add it _after_ having performed
 625         grammar sanity checks.
 626         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 627
 628 2001-12-29  Akim Demaille  <akim@epita.fr>
 629
 630         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 631         visible, and some states have now a different number.
 632
 633 2001-12-29  Akim Demaille  <akim@epita.fr>
 634
 635         * src/reader.c (readgram): Bind the initial rule's lineno to that
 636         of the first rule.
 637         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 638         (Solved SR Conflicts): Adjust rule 0's line number.
 639
 640 2001-12-29  Akim Demaille  <akim@epita.fr>
 641
 642         Fix the `GAWK Grammar' failure.
 643
 644         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 645         the reductions of the first state which was mistakenly confused
 646         with the final state because precisely final_state was initialized
 647         to 0.
 648         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 649         now noticed by Bison.
 650         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 651         have a reduction on $default.
 652
 653 2001-12-29  Akim Demaille  <akim@epita.fr>
 654
 655         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 656         rule line numbers.
 657         * src/closure.c (print_closure): Likewise.
 658         * src/derives.c (print_derives): Likewise.
 659         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 660         now.
 661
 662 2001-12-29  Akim Demaille  <akim@epita.fr>
 663
 664         * src/lalr.c (lookaheads_print): New.
 665         (lalr): Call it when --trace-flag.
 666         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 667         are dumped.
 668
 669 2001-12-29  Akim Demaille  <akim@epita.fr>
 670
 671         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 672         when walking through ritem, even via rule->rhs.
 673         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 674         (useful_production, useless_nonterminals): Likewise.
 675         (reduce_grammar_tables): Likewise, plus update nritems.
 676         * src/nullable.c (set_nullable): Likewise.
 677         * src/lalr.c (build_relations): Likewise.
 678         * tests/sets.at (Nullable): Adjust.
 679         Fortunately, now, the $axiom is no longer nullable.
 680
 681 2001-12-29  Akim Demaille  <akim@epita.fr>
 682
 683         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 684         the 0-sentinel.
 685         * src/gram.c (ritem_longest_rhs): Likewise.
 686         * src/reduce.c (nonterminals_reduce): Likewise.
 687         * src/print_graph.c (print_graph): Likewise.
 688         * src/output.c (output_rule_data): Likewise.
 689         * src/nullable.c (set_nullable):  Likewise.
 690
 691 2001-12-29  Akim Demaille  <akim@epita.fr>
 692
 693         * src/output.c: Comment changes.
 694
 695 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 696
 697         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 698         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 699         Sparc, as they were causing more porting problems than the
 700         (minor) performance improvement was worth.
 701
 702         Also, catch up with 1.31's YYSTD.
 703
 704 2001-12-27  Akim Demaille  <akim@epita.fr>
 705
 706         * src/output.c (output_gram): Rely on nritems, not the
 707         0-sentinel.  See below.
 708         Use -1 as separator, not 0.
 709         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 710         Rely on -1 as separator in yyrhs, instead of 0.
 711         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 712         twice `Now at end of input', therefore there are two lines less to
 713         expect.
 714
 715 2001-12-27  Akim Demaille  <akim@epita.fr>
 716
 717         * tests/regression.at (Unresolved SR Conflicts):
 718         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 719         below.
 720
 721 2001-12-27  Akim Demaille  <akim@epita.fr>
 722
 723         * src/LR0.c (new_state): Recognize the final state by the fact it
 724         is reached by eoftoken.
 725         (insert_start_shifting_state, insert_eof_shifting_state)
 726         (insert_accepting_state, augment_automaton): Remove, since now
 727         these states are automatically computed from the initial state.
 728         (generate_states): Adjust.
 729         * src/print.c: When reporting a rule number to the user, substract
 730         1, so that the axiom rule is rule 0, and the first user rule is 1.
 731         * src/reduce.c: Likewise.
 732         * src/print_graph.c (print_core): For the time being, just as for
 733         the report, depend upon --trace-flags to dump the full set of
 734         items.
 735         * src/reader.c (readgram): Once the grammar read, insert the rule
 736         0: `$axiom: START-SYMBOL $'.
 737         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 738         number of the states has changed (the final state is no longer
 739         necessarily the last), catch up.
 740
 741 2001-12-27  Akim Demaille  <akim@epita.fr>
 742
 743         Try to make the use of the eoftoken valid.  Given that its value
 744         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 745         is used instead of > 0 where appropriate, (ii), depend upon nritems
 746         instead of the 0-sentinel.
 747
 748         * src/gram.h, src/gram.c (nritems): New.
 749         Expected to be duplication of nitems, but for the time being...
 750         * src/reader.c (packgram): Assert nritems and nitems are equal.
 751         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 752         * src/closure.c (print_closure, print_fderives): Likewise.
 753         * src/gram.c (ritem_print): Likewise.
 754         * src/print.c (print_core, print_grammar): Likewise.
 755         * src/print_graph.c: Likewise.
 756
 757 2001-12-27  Akim Demaille  <akim@epita.fr>
 758
 759         * src/main.c (main): If there are complains after grammar
 760         reductions, then output the report anyway if requested, then die.
 761         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 762         * src/reader.c (eoftoken): New.
 763         (parse_token_decl): If the token being defined has value `0', it
 764         is the eoftoken.
 765         (packsymbols): No longer hack `tags' to insert `$' by hand.
 766         Be sure to preserve the value of the eoftoken.
 767         (reader): Make sure eoftoken is defined.
 768         Initialize nsyms to 0: now eoftoken is created just like the others.
 769         * src/print.c (print_grammar): Don't special case the eof token.
 770         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 771         lie anyway, albeit pleasant.
 772         * tests/calc.at: Exercise error messages with eoftoken.
 773         Change the grammar so that empty input is invalid.
 774         Adjust expectations.
 775         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 776
 777 2001-12-27  Akim Demaille  <akim@epita.fr>
 778
 779         * configure.in: Check the protos of strchr ans strspn.
 780         Replace strchr if needed.
 781         * src/system.h: Provide the protos of strchr, strspn and memchr if
 782         missing.
 783         * lib/strchr.c: New.
 784         * src/reader.c (symbols_save): Use strchr.
 785
 786 2001-12-27  Akim Demaille  <akim@epita.fr>
 787
 788         * src/print.c, src/print_graph.c (escape): New.
 789         Use it to quote the TAGS outputs.
 790         * src/print_graph.c (print_state): Now errors are in red, and
 791         reductions in green.
 792         Prefer high to wide: output the state number on a line of its own.
 793
 794 2001-12-27  Akim Demaille  <akim@epita.fr>
 795
 796         * src/state.h, src/state.c (reductions_new): New.
 797         * src/LR0.c (set_state_table): Let all the states have a
 798         `reductions', even if reduced to 0.
 799         (save_reductions): Adjust.
 800         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 801         * src/print.c (print_reductions, print_actions): Adjust.
 802         * src/output.c (action_row): Adjust.
 803
 804 2001-12-27  Akim Demaille  <akim@epita.fr>
 805
 806         * src/state.h, src/state.c (errs_new, errs_dup): New.
 807         * src/LR0.c (set_state_table): Let all the states have an errs,
 808         even if reduced to 0.
 809         * src/print.c (print_errs, print_reductions): Adjust.
 810         * src/output.c (output_actions, action_row): Adjust.

 812
 813 2001-12-27  Akim Demaille  <akim@epita.fr>
 814
 815         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 816
 817 2001-12-27  Akim Demaille  <akim@epita.fr>
 818
 819         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 820         * src/print.c: here.
 821         (lookaheadset, shiftset): New, used as additional storage by
 822         print_reductions.
 823         (print_results): Adjust.
 824         (print_shifts, print_gotos, print_errs): New, extracted from...
 825         (print_actions): here.
 826         * src/print_graph.c (print_actions): Remove dead code.
 827
 828 2001-12-27  Akim Demaille  <akim@epita.fr>
 829
 830         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 831         `$n' and `@n'.
 832
 833 2001-12-27  Akim Demaille  <akim@epita.fr>
 834
 835         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 836         (build_relations): Adjust.
 837
 838 2001-12-27  Akim Demaille  <akim@epita.fr>
 839
 840         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 841         duplication.
 842
 843 2001-12-27  Akim Demaille  <akim@epita.fr>
 844
 845         * src/reader.c (packgram): Catch nitems overflows.
 846
 847 2001-12-27  Akim Demaille  <akim@epita.fr>
 848
 849         * src/files.c, src/files.h (guard_obstack): Remove.
 850         * src/output.c (output): Adjust.
 851         * src/reader.c (parse_braces): New, factoring...
 852         (copy_action, copy_guard): these two which are renamed as...
 853         (parse_action, parse_guard): these.
 854         As a voluntary consequence, using braces around guards is now
 855         mandatory.
 856
 857 2001-12-27  Akim Demaille  <akim@epita.fr>
 858
 859         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 860         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 861         members.
 862         (symbol_list_new): Adjust.
 863         (copy_action): action_line is the first line, not the last.
 864         (copy_guard): Just as for actions, store the `action' only, not
 865         the switch/case/break flesh.
 866         Don't parse the user action that might follow the guard, let...
 867         (readgram): do it, i.e., now, there can be an action after a
 868         guard.
 869         In other words the guard is just explicitly optional.
 870         (packgram): Adjust.
 871         * src/output.c (guards_output): New.
 872         (output_parser): Call it when needed.
 873         (output): Also free the guard and attrs obstacks.
 874         * src/files.c, src/files.h (obstack_save): Remove.
 875         (output_files): Remove.
 876         As a result, if one needs the former `.act' file, using an
 877         appropriate skeleton which requires actions and guards is now
 878         required.
 879         * src/main.c (main): Adjust.
 880         * tests/semantic.at: New.
 881         * tests/regression.at: Use `input.y' as input file name.
 882         Avoid 8+3 problems by requiring input.c when the test needs the
 883         parser.
 884
 885 2001-12-27  Akim Demaille  <akim@epita.fr>
 886
 887         * src/reader.c (symbol_list_new): Be sure to initialize all the
 888         fields.
 889
 890 2001-12-27  Akim Demaille  <akim@epita.fr>
 891
 892         All the hacks using a final pseudo state are now useless.
 893
 894         * src/LR0.c (set_state_table): state_table holds exactly nstates.
 895         * src/lalr.c (nLA): New.
 896         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
 897         instead of lookaheadsp from the pseudo state (nstate + 1).
 898
 899 2001-12-27  Akim Demaille  <akim@epita.fr>
 900
 901         * src/output.c (action_row, token_actions): Use a state_t instead
 902         of a integer, and nlookaheads instead of the following state's
 903         lookaheadsp.
 904
 905 2001-12-27  Akim Demaille  <akim@epita.fr>
 906
 907         * src/conflicts.c (log_resolution, flush_shift)
 908         (resolve_sr_conflict, set_conflicts, solve_conflicts)
 909         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
 910         (conflicts_print, print_reductions): Use a state_t instead of an
 911         integer when referring to a state.
 912         As much as possible, depend upon nlookaheads, instead of the
 913         `lookaheadsp' member of the following state (since lookaheads of
 914         successive states are successive, the difference between state n + 1
 915         and n served as the number of lookaheads for state n).
 916         * src/lalr.c (add_lookback_edge): Likewise.
 917         * src/print.c (print_core, print_actions, print_state)
 918         (print_results): Likewise.
 919         * src/print_graph.c (print_core, print_actions, print_state)
 920         (print_graph): Likewise.
 921         * src/conflicts.h: Adjust.
 922
 923 2001-12-27  Akim Demaille  <akim@epita.fr>
 924
 925         * src/bison.hairy: Formatting/comment changes.
 926         ANSIfy.
 927         Remove `register' indications.
 928         Add plenty of `static'.
 929
 930 2001-12-27  Akim Demaille  <akim@epita.fr>
 931
 932         * src/output.c (prepare): Drop the muscle `ntbase' which
 933         duplicates ntokens.
 934         * src/bison.simple: Formatting/comment changes.
 935         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
 936         is an undocumented synonym.
 937
 938 2001-12-22  Akim Demaille  <akim@epita.fr>
 939
 940         * src/output.c (output_table_data): Change the prototype to use
 941         `int' for array ranges: some invocations do pass an int, not a
 942         short.
 943         Reported by Wayne Green.

 945 2001-12-22  Akim Demaille  <akim@epita.fr>

 947         Some actions of web2c.y are improperly triggered.
 948         Reported by Mike Castle.
 949
 950         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
 951         * tests/regression.at (Web2c): Rename as...
 952         (Web2c Report): this.
 953         (Web2c Actions): New.
 954
 955 2001-12-22  Akim Demaille  <akim@epita.fr>
 956
 957         Reductions in web2c.y are improperly reported.
 958         Reported by Mike Castle.
 959
 960         * src/conflicts.c (print_reductions): Fix.
 961         * tests/regression.at (Web2c): New.
 962
 963 2001-12-18  Akim Demaille  <akim@epita.fr>
 964
 965         Some host fail on `assert (!"foo")', which expands to
 966         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
 967         Reported by Nelson Beebee.
 968
 969         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
 970         `#define it_succeeded 0' and `assert (it_succeeded)'.
 971
 972 2001-12-17  Marc Autret  <autret_m@epita.fr>
 973
 974         * src/bison.simple: Don't hard code the skeleton line and filename.
 975         * src/output.c (output_parser): Rename 'line' as 'output_line'.
 976         New line counter 'skeleton_line' (skeleton-line muscle).
 977
 978 2001-12-17  Paul Eggert  <eggert@twinsun.com>
 979
 980         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
 981         YYDEBUG must be defined to a nonzero value.
 982
 983         * src/bison.simple (yytname): Do not assume that the user defines
 984         YYDEBUG to a properly parenthesized expression.
 985
 986 2001-12-17  Akim Demaille  <akim@epita.fr>
 987
 988         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
 989         nlookaheads is a new member.
 990         Adjust all users.
 991         * src/lalr.h (nlookaheads): Remove this orphan declaration.

 993         state.
 994
 995 2001-12-17  Akim Demaille  <akim@epita.fr>
 996
 997         * src/files.h, src/files.c (open_files, close_files): Remove.
 998         * src/main.c (main): Don't open/close files, nor invoke lex_free,
 999         let...
1000         * src/reader.c (reader): Do it.
1001
1002 2001-12-17  Akim Demaille  <akim@epita.fr>
1003
1004         * src/conflicts.c (print_reductions): Formatting changes.
1005
1006 2001-12-17  Akim Demaille  <akim@epita.fr>
1007
1008         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
1009         (flush_reduce): New.
1010         (resolve_sr_conflict): Adjust.
1011
1012 2001-12-17  Akim Demaille  <akim@epita.fr>
1013
1014         * src/output.c (output_obstack): Be static and rename as...
1015         (format_obstack): this, to avoid any confusion with files.c's
1016         output_obstack.
1017         * src/reader.h (muscle_obstack): Move to...
1018         * src/output.h: here, since it's defined in output.c.
1019
1020 2001-12-17  Akim Demaille  <akim@epita.fr>
1021
1022         * src/output.c (action_row, save_column, default_goto)

1024         locality.

1029
1030 2001-12-17  Akim Demaille  <akim@epita.fr>
1031

1039
1040         * src/output.c (actions_output): Fix. When we use %no-lines,
1041         there is one less line per action.
1042
1043 2001-12-16  Marc Autret  <autret_m@epita.fr>
1044
1045         * src/bison.simple: Remove a useless #line directive.
1046         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1047         * src/output.c (get_lines_number): New.
1048         (output_parser): Adjust, now takes care about the lines of a
1049         output muscles.
1050         Fix line numbering.
1051         (actions_output): Computes the number of lines taken by actions.
1052         (output_master_parser): Insert new skeleton which is the name of
1053         the output parser file name.
1054
1055 2001-12-15  Marc Autret  <autret_m@epita.fr>
1056
1057         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
1058
1059 2001-12-15  Marc Autret  <autret_m@epita.fr>
1060

1062
1063 2001-12-15  Akim Demaille  <akim@epita.fr>
1064
1065         Make `make distcheck' work.
1066
1067         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1068         system.h which uses libgettext.h.
1069
1070 2001-12-15  Akim Demaille  <akim@epita.fr>
1071
1072         * src/nullable.c (set_nullable): Useless rules must be skipped,
1073         otherwise, since we range over their symbols, we might look at a
1074         nonterminal which no longer ``exists'', i.e., it is not counted in
1075         `nvars', hence we overflow our arrays.
1076
1077 2001-12-15  Akim Demaille  <akim@epita.fr>
1078
1079         The header can also be produced directly, without any obstack!
1080         Yahoo!
1081
1082         * src/files.c, src/files.h (defines_obstack): Remove.
1083         (compute_header_macro): Global.
1084         (defines_obstack_save): Remove.
1085         * src/reader.c (parse_union_decl): No longer output to
1086         defines_obstack: its content can be found in the `stype' muscle
1087         anyway.
1088         (output_token_translations): Merge into...
1089         (symbols_output): this.

1096 2001-12-15  Akim Demaille  <akim@epita.fr>
1097
1098         * src/reader.c (parse_union_decl): Instead of handling two obstack
1099         simultaneously, use one to define the `stype' muscle, and use the
1100         value of the latter to fill defines_obstack.
1101         (copy_comment): Remove.
1102         (copy_comment2): Work for a single obstack.
1103         Rename as...
1104         (copy_comment): this.
1105
1106 2001-12-15  Akim Demaille  <akim@epita.fr>
1107
1108         * src/lex.c, src/lex.h (xgetc): No longer static.
1109         * src/reader.c (parse_union_decl): Revamp.
1110
1111 2001-12-15  Akim Demaille  <akim@epita.fr>
1112
1113         Still making progress in separating Bison into (i) input, (ii)
1114         process, (iii) output: now we can directly output the parser file
1115         without using table_obstack at all.
1116
1117         * src/files.c, src/files.h (table_obstack): Bye bye.
1118         (parser_file_name): New.
1119         * src/files.c (compute_output_file_names): Compute it.
1120         * src/output.c (actions_output, output_parser)
1121         (output_master_parser): To a file instead of an obstack.
1122
1123 2001-12-15  Akim Demaille  <akim@epita.fr>
1124
1125         Attach actions to rules, instead of pre-outputting them to
1126         actions_obstack.
1127
1128         * src/gram.h (rule_t): action and action_line are new members.
1129         * src/reader.c (symbol_list): Likewise.
1130         (copy_action): Save the actions within the rule.
1131         (packgram): Save them in rule_table.
1132         * src/output.c (actions_output): New.
1133         (output_parser): Use it on `%%actions'.
1134         (output_rule_data): Don't free rule_table.
1135         (output): Do it.
1136         (prepare): Don't save the `action' muscle.
1137         * src/bison.simple: s/%%action/%%actions/.
1138
1139 2001-12-15  Akim Demaille  <akim@epita.fr>
1140
1141         * src/reader.c (copy_action): When --yacc, don't append a `;'
1142         to the user action: let it fail if lacking.
1143         Suggested by Arnold Robbins and Tom Tromey.
1144
1145 2001-12-14  Akim Demaille  <akim@epita.fr>
1146
1147         * src/lex.c (literalchar): Simply return the char you decoded, non
1148         longer mess around with obstacks and int pointers.
1149         Adjust all callers.
1150
1151 2001-12-14  Akim Demaille  <akim@epita.fr>
1152
1153         * src/lex.c (literalchar): Don't escape the special characters,
1154         just decode them, and keep them as char (before, eol was output as
1155         the 2 char string `\n' etc.).
1156         * src/output.c (output_rule_data): Use quotearg to output the
1157         token strings.
1158
1159 2001-12-13  Paul Eggert  <eggert@twinsun.com>
1160
1161         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1162         Do not infringe on the global user namespace when using C++.
1163         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1164         All uses of `fprintf' and `stderr' changed.
1165
1166         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1167
1168 2001-12-13  Akim Demaille  <akim@epita.fr>
1169
1170         The computation of nullable is broken: it doesn't handle empty
1171         RHS's properly.
1172
1173         * tests/torture.at (GNU AWK Grammar): New.
1174         * tests/sets.at (Nullable): New.
1175         * src/nullable.c (set_nullable): Instead of blindly looping over
1176         `ritems', loop over the rules, and then over their rhs's.
1177
1178         Work around Autotest bugs.
1179
1180         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1181         frame, because Autotest understand lines starting with a `+' as
1182         traces from the shell.  Then, they are not processed properly.
1183         Admittedly an Autotest bug, but we don't have time to wait for
1184         Autotest to catch up.
1185         * tests/regression.at (Broken Closure): Adjust to the new table
1186         frames.
1187         Move to...
1188         * tests/sets.at: here.
1189
1190 2001-12-13  Akim Demaille  <akim@epita.fr>
1191
1192         * src/closure.c (closure): Use nrules instead of playing tricks
1193         with BITS_PER_WORD.
1194
1195 2001-12-13  Akim Demaille  <akim@epita.fr>
1196
1197         * src/print.c (print_actions): Output the handling of `$' as the
1198         traces do: shifting the token EOF.  Before EOF was treated as a
1199         nonterminal.
1200         * tests/regression.at: Adjust some tests.
1201         * src/print_graph.c (print_core): Complete the set of items via
1202         closure.  The next-to-final and final states are still unsatisfying,
1203         but that's to be addressed elsewhere.
1204         No longer output the rule numbers, but do output the state number.
1205         A single loop for the shifts + gotos is enough, but picked a
1206         distinct color for each.
1207         (print_graph): Initialize and finalize closure.
1208
1209 2001-12-13  Akim Demaille  <akim@epita.fr>
1210
1211         * src/reader.c (readgram): Remove dead code, an strip useless
1212         braces.
1213         (get_type): Remove, unused.
1214
1215 2001-12-12  Akim Demaille  <akim@epita.fr>
1216
1217         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1218         on that of lib/error.c.
1219
1220 2001-12-12  Akim Demaille  <akim@epita.fr>
1221
1222         Some hosts don't like `/' in includes.
1223
1224         * src/system.h: Include libgettext.h without qualifying the path.
1225         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1226         $(top_srcdir).
1227
1228 2001-12-11  Marc Autret  <autret_m@epita.fr>
1229
1230         * src/output.c (output_parser): Remove useless muscle.
1231
1232 2001-12-11  Marc Autret  <autret_m@epita.fr>
1233
1234         * src/bison.simple: Remove #line just before %%epilogue. It
1235         is now handled in ...
1236         * src/reader.c (read_additionnal_code): Add the output of a
1237         #line for the epilogue.
1238
1239 2001-12-10  Marc Autret  <autret_m@epita.fr>
1240
1241         * src/reader.c (copy_definition): Re-use CPP-outed code which
1242         replace precedent remove.
1243         * src/bison.simple: Remove #line before %%prologue because
1244         %%input-line is wrong at this time.
1245
1246 2001-12-10  Marc Autret  <autret_m@epita.fr>
1247
1248         * src/reader.c (symbols_output): Clean up.
1249         * src/output.c (output_gram, output): Clean up.
1250
1251 2001-12-10  Akim Demaille  <akim@epita.fr>
1252
1253         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
1254         * src/LR0.c (set_state_table): here.
1255         * src/lalr.c (lalr): Call it.
1256
1257 2001-12-10  Akim Demaille  <akim@epita.fr>
1258
1259         * src/state.h (shifts): Remove the `number' member: shifts are
1260         attached to state, hence no longer need to be labelled with a
1261         state number.
1262
1263 2001-12-10  Akim Demaille  <akim@epita.fr>
1264
1265         Now that states have a complete set of members, the linked list of
1266         shifts is useless: just fill directly the state's shifts member.
1267
1268         * src/state.h (shifts): Remove the `next' member.
1269         * src/LR0.c (first_state, last_state): Remove.
1270         Adjust the callers.
1271         (augment_automaton): Don't look for the shifts that must be added
1272         a shift on EOF: it is those of the state we looked for!  But now,
1273         since shifts are attached, it is no longer needed to looking
1274         merely by its id: its number.
1275
1276 2001-12-10  Akim Demaille  <akim@epita.fr>
1277
1278         * src/LR0.c (augment_automaton): Better variable locality.
1279         Remove an impossible branch: if there is a state corresponding to
1280         the start symbol being shifted, then there is shift for the start
1281         symbol from the initial state.
1282
1283 2001-12-10  Akim Demaille  <akim@epita.fr>
1284
1285         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1286         only when appropriate: when insert_start_shifting_state' is not
1287         invoked.
1288         * tests/regression.at (Rule Line Numbers): Adjust.
1289
1290 2001-12-10  Akim Demaille  <akim@epita.fr>
1291
1292         * src/LR0.c (augment_automaton): Now that all states have shifts,
1293         merge the two cases addition shifts to the initial state.
1294
1295 2001-12-10  Akim Demaille  <akim@epita.fr>
1296
1297         * src/lalr.c (set_state_table): Move to...
1298         * src/LR0.c: here.
1299         * src/lalr.c (lalr): Don't call it...
1300         * src/LR0.c (generate_states): do it.
1301         * src/LR0.h (first_state): Remove, only the table is used.
1302
1303 2001-12-10  Akim Demaille  <akim@epita.fr>
1304
1305         * src/LR0.h (first_shift, first_reduction): Remove.
1306         * src/lalr.c: Don't use first_shift: find shifts through the
1307         states.
1308
1309 2001-12-10  Akim Demaille  <akim@epita.fr>
1310
1311         * src/LR0.c: Attach shifts to states as soon as they are
1312         computed.
1313         * src/lalr.c (set_state_table): Instead of assigning shifts to
1314         state, just assert that the mapping was properly done.
1315
1316 2001-12-10  Akim Demaille  <akim@epita.fr>
1317
1318         * src/LR0.c (insert_start_shift): Rename as...
1319         (insert_start_shifting_state): this.
1320         (insert_eof_shifting_state, insert_accepting_state): New.
1321         (augment_automaton): Adjust.
1322         Better locality of the variables.
1323         When looking if the start_symbol is shifted from the initial
1324         state, using `while (... symbol != start_symbol ...)' sounds
1325         better than `while (... symbol < start_symbol ...)': If fail
1326         to see how the order between symbols could be relevant!
1327
1328 2001-12-10  Akim Demaille  <akim@epita.fr>
1329
1330         * src/getargs.h: Don't declare `spec_name_prefix' and
1331         `spec_file_prefix', declared by src/files.h.
1332         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1333         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1334         * src/output.c (prepare): Adjust.
1335         * src/reader.c (symbols_output): Likewise.
1336         * src/vmsgetargs.c: Vaguely adjust, but who cares?
1337
1338 2001-12-10  Akim Demaille  <akim@epita.fr>
1339
1340         * src/muscle_tab.c (muscle_init): NULL is a better default than
1341         `"0"'.
1342
1343 2001-12-10  Akim Demaille  <akim@epita.fr>
1344
1345         * src/reader.c (reader): Calling symbols_output once is enough.
1346
1347 2001-12-10  Akim Demaille  <akim@epita.fr>
1348
1349         Now that states have a complete set of members, the linked list of
1350         reductions is useless: just fill directly the state's reductions
1351         member.
1352
1353         * src/state.h (struct reductions): Remove member `number' and
1354         `next'.
1355         * src/LR0.c (first_reduction, last_reduction): Remove.
1356         (save_reductions): Don't link the new reductions, store them in
1357         this_state.
1358         * src/lalr.c (set_state_table): No need to attach reductions to
1359         states, it's already done.
1360         * src/output.c (output_actions): No longer free the shifts, then
1361         the reductions, then the states: free all the states and their
1362         members.
1363
1364 2001-12-10  Akim Demaille  <akim@epita.fr>
1365
1366         * src/options.c (OPTN, DRTV, BOTH): New.
1367         (option_table): Use them.
1368
1369         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1370         the job of system.h.
1371         * src/options.c: Don't include stdio.h and xalloc.h for the same
1372         reasons.
1373
1374 2001-12-10  Akim Demaille  <akim@epita.fr>
1375
1376         * src/output.c (output, prepare): Make sure the values of the
1377         muscles `action' and `prologue' are 0-terminated.
1378
1379 2001-12-10  Akim Demaille  <akim@epita.fr>
1380
1381         Clean up GCC warnings.
1382
1383         * src/reader.c (copy_action): `buf' is not used.
1384         (parse_skel_decl): Be static.
1385         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1386         * src/options.h (create_long_option_table): Have a real prototype.
1387         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1388         (hash_delete_at): Return const void *.
1389         Adjust casts to preserve the const.
1390
1391 2001-12-10  Akim Demaille  <akim@epita.fr>
1392
1393         * configure.in: Require 2.52g.
1394         M4 is not needed, but AUTOM4TE is.
1395         * m4/m4.m4: Remove.
1396         * tests/Makefile.am: Adjust.
1397
1398 2001-12-10  Akim Demaille  <akim@epita.fr>
1399
1400         One structure for states is enough, even though theoretically
1401         there are LR(0) states and LALR(1) states.
1402
1403         * src/lalr.h (state_t): Remove.
1404         (state_table): Be state_t **, not state_t *.
1405         * src/state.h (core, CORE_ALLOC): Rename as...
1406         (state_t, STATE_ALLOC): this.
1407         Add the LALR(1) members: shifts, reductions, errs.
1408         * src/LR0.c (state_table): Rename as...
1409         (state_hash): this, to avoid name clashes with the global
1410         `state_table'.
1411         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1412         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

1416         Bison dumps core on bash.y.
1417         Reported by Pascal Bart.
1418
1419         * src/warshall.c (bitmatrix_print): New.
1420         (TC): Use it.
1421         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1422         j must be the outer loop.
1423         * tests/regression.at (Broken Closure): New.

1435         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1436         Rename as...

1438
1439 2001-12-05  Akim Demaille  <akim@epita.fr>
1440
1441         * src/reduce.c (reduce_grammar_tables): No longer disable the
1442         removal of useless rules via CPP but via `if (0)', so that the
1443         compiler still check the code is valid.
1444         For instance, it should have noticed `rline' no longer exists: use
1445         the `line' member of rule_t.
1446         * src/gram.c (dummy, rline): Remove, unused.
1447

1455         New experimental feature: if --verbose --trace output all the
1456         items of a state, not only its kernel.
1457
1458         * src/print.c (print_core): If `trace_flag', then invoke closure
1459         before outputting the items of the state (print_core is no longer
1460         a correct name them).
1461         (print_results): Invoke new_closure/free_closure if needed.
1462
1463 2001-12-05  Akim Demaille  <akim@epita.fr>
1464
1465         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1466         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1467         (nitemset): for consistency with the rest of the project.
1468
1469 2001-12-05  Akim Demaille  <akim@epita.fr>
1470
1471         * src/closure.c (print_closure): Improve.
1472         (closure): Use it for printing input and output.
1473
1474 2001-12-05  Akim Demaille  <akim@epita.fr>
1475
1476         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1477         indexed by nonterminals.
1478
1479 2001-12-05  Akim Demaille  <akim@epita.fr>
1480
1481         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1482         what it was!).
1483         * src/warshall.h: Remove accidental duplication of the content.
1484
1485 2001-12-05  Akim Demaille  <akim@epita.fr>
1486
1487         * src/closure.c (set_fderives): De-obfuscate.
1488
1489 2001-12-05  Akim Demaille  <akim@epita.fr>
1490
1491         * src/closure.c (print_firsts, print_fderives): De-obfuscate.
1492
1493 2001-12-05  Akim Demaille  <akim@epita.fr>
1494
1495         * src/closure.c (set_firsts): De-obfuscate.
1496
1497 2001-12-05  Akim Demaille  <akim@epita.fr>
1498
1499         * src/output.c (action_row): De-obfuscate
1500         using the good o' techniques: arrays not pointers, variable
1501         locality, BITISSET, RESETBIT etc.
1502
1503 2001-12-05  Akim Demaille  <akim@epita.fr>
1504
1505         Pessimize the code to simplify it: from now on, all the states
1506         have a valid SHIFTS, which NSHIFTS is possibly 0.
1507
1508         * src/LR0.c (shifts_new): Be global and move to..
1509         * src/state.c, src/state.h: here.
1510         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1511         * src/print_graph: Adjust.
1512
1513 2001-12-05  Akim Demaille  <akim@epita.fr>
1514
1515         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1516         * src/conflicts.c: Use it.
1517         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1518         incorrectly ``simplified''.
1519
1520 2001-12-05  Akim Demaille  <akim@epita.fr>
1521
1522         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1523         using the good o' techniques: arrays not pointers, variable
1524         locality, BITISSET, RESETBIT etc.
1525
1526 2001-12-05  Akim Demaille  <akim@epita.fr>
1527
1528         * src/state.h (SHIFT_SYMBOL): New.
1529         * src/conflicts.c: Use it to deobfuscate.
1530
1531 2001-12-05  Akim Demaille  <akim@epita.fr>
1532
1533         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1534         (print_reductions): De-obfuscate using the good o' techniques:
1535         arrays not pointers, variable locality, BITISSET.
1536
1537 2001-12-05  Akim Demaille  <akim@epita.fr>
1538
1539         * src/conflicts.c (print_reductions): Arrays, not pointers.
1540         Use BITISSET.
1541
1542 2001-12-05  Akim Demaille  <akim@epita.fr>
1543
1544         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1545
1546 2001-12-05  Akim Demaille  <akim@epita.fr>
1547
1548         * src/conflicts.c (print_reductions): Improve variable locality.
1549
1550 2001-12-05  Akim Demaille  <akim@epita.fr>
1551
1552         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1553
1554 2001-12-05  Akim Demaille  <akim@epita.fr>
1555
1556         * src/conflicts.c (print_reductions): Improve variable locality.
1557
1558 2001-12-05  Akim Demaille  <akim@epita.fr>
1559
1560         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
1561         * src/lalr.c: Use them.
1562
1563 2001-12-05  Akim Demaille  <akim@epita.fr>
1564
1565         * src/LR0.c (augment_automaton): Formatting changes.
1566         Better variable locality.
1567
1568 2001-12-05  Akim Demaille  <akim@epita.fr>
1569
1570         * src/lalr.c (matrix_print): New.
1571         (transpose): Use it.
1572         Use arrays instead of pointers.
1573
1574 2001-12-05  Akim Demaille  <akim@epita.fr>
1575
1576         * src/lalr.c (maxrhs): Move to...
1577         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1578         * src/lalr.c (build_relations): Adjust.
1579
1580 2001-12-05  Akim Demaille  <akim@epita.fr>
1581
1582         * src/lalr.c (transpose): Free the memory allocated to the
1583         argument, as it is replaced by the results by the unique caller.
1584         (build_relations): Merely invoke transpose: it handles the memory
1585         deallocation.
1586         Improve variable locality.
1587         Avoid variables used as mere abbreviations.
1588         (compute_lookaheads): Use arrays instead of pointers.
1589
1590 2001-12-05  Akim Demaille  <akim@epita.fr>
1591
1592         * src/lalr.c (initialize_F): Improve variable locality.
1593         Avoid variables used as mere abbreviations.
1594
1595 2001-12-05  Akim Demaille  <akim@epita.fr>
1596
1597         * src/derives.c (print_derives): Display the ruleno.
1598         * src/lalr.c (initialize_F, transpose): Better variable locality
1599         to improve readability.
1600         Avoid variables used as mere abbreviations.
1601
1602 2001-12-05  Akim Demaille  <akim@epita.fr>
1603
1604         * src/lalr.c (traverse): Use arrays instead of pointers.
1605
1606 2001-12-05  Akim Demaille  <akim@epita.fr>
1607
1608         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1609         the handling of squeue.
1610         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1611
1612 2001-12-05  Akim Demaille  <akim@epita.fr>
1613
1614         Because useless nonterminals are now kept alive (instead of being
1615         `destroyed'), we now sometimes examine them, and store information
1616         related to them.  Hence we need to know their number, and adjust
1617         memory allocations.
1618
1619         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1620         static.
1621         * src/LR0.c (allocate_itemsets): The memory allocated to
1622         `symbol_count' was used for two different purpose: once to count
1623         the number of occurrences of each symbol, and later reassigned to
1624         `shift_symbol', containing the symbol that can be shifted from a
1625         given state.
1626         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1627         only, and...
1628         (new_itemsets): Allocate `shift_symbol' here.
1629         (allocate_itemsets): symbol_count includes useless nonterminals.
1630         Make room for them.
1631         (free_storage): Use `free', not `XFREE', for pointers that cannot
1632         be null.
1633
1634 2001-12-05  Akim Demaille  <akim@epita.fr>
1635
1636         * src/nullable.c (set_nullable): Deobfuscate the handling of
1637         ritem.
1638         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1639
1640 2001-12-05  Akim Demaille  <akim@epita.fr>
1641
1642         * src/gram.c, src/gram.h (ritem_print): New.
1643         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1644         (This useless function was defined only to work around VMS linkers
1645         that can't handle compilation units with variables only).
1646         * src/reduce.c (dump_grammar): Use it to trace the construction of
1647         ritem.
1648
1649 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1650
1651         * src/bison.simple (union yyalloc): Change member names
1652         to be the same as the stack names.
1653         (yyparse): yyptr is now union yyalloc *, not char *.
1654         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1655         and may generate better code on some machines.
1656         (yystpcpy): Use prototype if __STDC__ is defined, not just
1657         if __cplusplus is defined.
1658
1659 2001-11-30  Akim Demaille  <akim@epita.fr>
1660
1661         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1662         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1663         Gettext doesn't compile cleanly, and dies with -Werror.
1664         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1665         Include WARNING_CFLAGS here.
1666         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1667         before being defined.
1668
1669 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1670
1671         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1672         First arg is int, not unsigned.
1673         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1674         (SIZE_MAX, UINT_MAX): New macros.
1675         (quotearg_n_options): Abort if N is negative.
1676         Avoid overflow check on hosts where size_t is 64 bits and int
1677         is 32 bits, as overflow is impossible there.
1678         Fix off-by-one typo that caused unnecessary reallocation.
1679
1680 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1681
1682         Name space cleanup in generated parser.
1683
1684         * doc/bison.texinfo (Bison Parser): Discuss system headers
1685         and their effect on the user name space.
1686
1687         * src/bison.simple:
1688         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1689         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1690         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1691
1692         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1693         on user names when possible.
1694
1695         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1696         Simplify test for whather <alloca.h> exists.
1697
1698         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1699
1700         (<stdio.h>): Include if YYDEBUG.
1701
1702         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
1703         ! defined (yyoverflow) && ! defined (yymemcpy).
1704
1705         (yymemcpy, yyparse): Rename local variables as needed so that
1706         they all begin with 'yy'.
1707
1708         (yystrlen, yystpcpy): New functions.
1709
1710         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1711         All uses changed.
1712
1713         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1714         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1715         and YYSTACK_FREE instead of malloc and free.
1716
1717 2001-11-30  Akim Demaille  <akim@epita.fr>
1718
1719         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
1720         before their first uses.
1721         (YYBISON, YYPURE): Move to the top of the output.
1722
1723 2001-11-30  Akim Demaille  <akim@epita.fr>
1724
1725         * tests/reduce.at (Useless Nonterminals): Fix.
1726
1727 2001-11-30  Akim Demaille  <akim@epita.fr>
1728
1729         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1730         if body instead of `;' to pacify GCC's warnings.
1731
1732 2001-11-30  Akim Demaille  <akim@epita.fr>
1733
1734         Instead of mapping the LHS of unused rules to -1, keep the LHS
1735         valid, but flag the rules as invalid.
1736
1737         * src/gram.h (rule_t): `useful' is a new member.
1738         * src/print.c (print_grammar): Adjust.
1739         * src/derives.c (set_derives): Likewise.
1740         * src/reader.c (packgram, reduce_output): Likewise.
1741         * src/reduce.c (reduce_grammar_tables): Likewise.
1742         * tests/reduce.at (Underivable Rules, Useless Rules): New.
1743
1744 2001-11-30  Akim Demaille  <akim@epita.fr>
1745
1746         * src/reduce.c (reduce_output): Formatting changes.
1747         * src/print.c (print_results, print_grammar): Likewise.
1748         * tests/regression.at (Rule Line Numbers)
1749         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
1750
1751 2001-11-30  Akim Demaille  <akim@epita.fr>
1752
1753         * src/reduce.c (nonterminals_reduce): Instead of throwing away
1754         useless nonterminals, move them at the end of the symbol arrays.
1755         (reduce_output): Adjust.
1756         * tests/reduce.at (Useless Nonterminals): Adjust.
1757
1758 2001-11-30  Akim Demaille  <akim@epita.fr>
1759
1760         * src/reduce.c: Various comment/formatting changes.
1761         (nonterminals_reduce): New, extracted from...
1762         (reduce_grammar_tables): here.
1763         (reduce_grammar): Call nonterminals_reduce.
1764
1765 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1766
1767         * src/bison.simple (YYSTACK_REALLOC): Remove.
1768         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
1769         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
1770         New macros.
1771         (union yyalloc): New type.
1772         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1773         an arbitrary restriction on hosts where size_t is wider than int.
1774
1775         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1776         a parser stack overflow.  Allocate just one block of memory for all
1777         three stacks, instead of allocating three blocks; this typically is
1778         faster and reduces fragmentation.
1779
1780         Do not limit the number of items in the stack to a value that fits
1781         in 'int', as this is an arbitrary limit on hosts with 64-bit
1782         size_t and 32-bit int.
1783
1784 2001-11-29  Marc Autret  <autret_m@epita.fr>
1785
1786         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
1787         of defining YYERROR_VERBOSE.
1788         [AT_DATA]: $4 is now out of C declarations in the prologue.
1789
1790 2001-11-28  Marc Autret  <autret_m@epita.fr>
1791
1792         * src/reader.c (parse_dquoted_param): New.
1793         (parse_skel_decl): Use it.
1794         * src/lex.h: Add its prototype.
1795         * src/lex.c (literalchar): Become not static.
1796
1797 2001-11-28  Marc Autret  <autret_m@epita.fr>
1798
1799         * src/output.h: And put its extern declaration here.
1800         * src/output.c (error_verbose): Define here.
1801         (prepare): Echo name modification.
1802         * src/getargs.h: Clean its extern declaration.
1803         * src/getargs.c (error_verbose_flag): Remove.
1804         (getargs): Remove case 'e'.
1805         * src/options.c (option_table): 'error-verbose' is now seen as simple
1806         percent option.
1807         Include output.h.
1808
1809         * src/reader.c (read_declarations): Remove case tok_include.
1810         (parse_include_decl): Remove.

2210         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
2211         now the tests are run in private dirs, therefore AC_CLEANUP and

2239         arg_offset.

2338         * src/reader.c (parse_union_decl): Output yystype/YYSTYPE as we do
2339         with yyltype/YYLTYPE.  This allows inclusion of the generated

3593         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
3594         New, from fileutils 4.0.37.
3595         * configure.in: Require Autoconf 2.49c.  I took some time before
3596         making this decision.  This is the only way out for portability
3597         issues in Bison, it would mean way too much duplicate effort to
3598         import in Bison features implemented in 2.49c since 2.13.
3599         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

3606 2001-01-19  Akim Demaille  <akim@epita.fr>
3607
3608         Get rid of the ad hoc handling of token_buffer in the scanner: use
3609         the obstacks.
3610
3611         * src/lex.c (token_obstack): New.
3612         (init_lex): Initialize it.  No longer call...
3613         (grow_token_buffer): this.  Remove it.
3614         Adjust all the places which used it to use the obstack.
3615
3616 2001-01-19  Akim Demaille  <akim@epita.fr>
3617
3618         * src/lex.h: Rename all the tokens:
3619         s/\bENDFILE\b/tok_eof/g;
3620         s/\bIDENTIFIER\b/tok_identifier/g;
3621         etc.
3622         Let them be enums, not #define, to ease debugging.
3623         Adjust all the code.
3624
3625 2001-01-18  Akim Demaille  <akim@epita.fr>

3631
3632         Since we now use obstacks, more % directives can be enabled.
3633
3634         * src/lex.c (percent_table): Also accept `%yacc',
3635         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3636         `%debug'.
3637         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3638         instead of returning a token.
3639         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3640         * src/reader.c (read_declarations): Adjust.
3641         * src/files.c (open_files): Don't call `compute_base_names', don't
3642         compute `attrsfile' since they depend upon data which might be
3643         *in* the input file now.
3644         (output_files): Do it here.
3645         * src/output.c (output_headers): Document the fact that this patch
3646         introduces a guaranteed SEGV for semantic parsers.
3647         * doc/bison.texinfo: Document them.
3648         * tests/suite.at: Exercise these %options.
3649
3650 2000-12-20  Akim Demaille  <akim@epita.fr>
3651

3671         FILE * parameters.
3672
3673 2000-12-20  Akim Demaille  <akim@epita.fr>
3674
3675         * src/files.c (open_files): Actually the `.output' file is based
3676         on the short_base_name, not base_name.
3677         * tests/suite.at (Checking output file names): Adjust.
3678
3679 2000-12-20  Akim Demaille  <akim@epita.fr>
3680
3681         * src/bison.s1: Remove, we now use directly...

3683         * src/Makefile.am: Use pkgdata instead of data.
3684

3703
3704         * src/files.c (strsuffix): New.
3705         (stringappend): Be just like strcat but allocate.
3706         (base_names): Eve out from open_files.
3707         Try to simplify the rather hairy computation of base_name and
3708         short_base_name.

3710         * tests/suite.at (Checking output file names): New test.

3720
3721 2000-12-19  Akim Demaille  <akim@epita.fr>
3722
3723         * src/output.c (output_parser): Compute the `#line' lines when
3724         there are.

3727
3728 2000-12-19  Akim Demaille  <akim@epita.fr>
3729
3730         Let the handling of the skeleton files be local to the procedures
3731         that use it.
3732
3733         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
3734         longer static.

3748 2000-12-19  Akim Demaille  <akim@epita.fr>
3749
3750         * src/files.c (open_files): Yipee!  We no longer need all the code
3751         looking for `/tmp' since we have no tmp file.
3752

3782         * lib/obstack.h: Formatting changes.
3783         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3784         prevents type checking.
3785         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3786         cast the value to (void *): assigning a `foo *' to a `void *'
3787         variable is valid.
3788         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3789         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

3824
3825 2000-11-07  Akim Demaille  <akim@epita.fr>
3826
3827         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
3828         Merge in a single CPP if/else.

3833         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
3834         argument `data' for consistency with the prototypes.

3837         `address' for consistency.  Qualify it `const'.

3869         * src/main.c (main): Don't use `atexit' to register `done', since
3870         it no longer has to remove tmp files, just call `output_files'
3871         when there are no errors.
3872

3976         When a literal string is used to define two different tokens,
3977         `bison -v' segfaults.
3978         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3979
3980         * tests/regression.m4: New file.
3981         Include the core of the sample provided by Piotr Gackiewicz.
3982         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
3983         properly.
3984
3985 2000-10-04  Akim Demaille  <akim@epita.fr>
3986
3987         * src/reader.c (parse_expect_decl): Keep `count' within the size

3990
3991 2000-10-02  Paul Eggert  <eggert@twinsun.com>
3992
3993         * bison.s1 (yyparse): Assign the default value
3994         unconditionally, to avoid a GCC warning and make the parser a
3995         tad smaller.
3996
3997 2000-10-02  Akim Demaille  <akim@epita.fr>
3998
3999         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
4000         options.
4001
4002 2000-10-02  Akim Demaille  <akim@epita.fr>
4003
4004         * src/derives.c, src/print.c, src/reduce.c: To ease the
4005         translation, move some `\n' out of the translated strings.
4006
4007 2000-10-02  Akim Demaille  <akim@epita.fr>
4008
4009         The location tracking mechanism is precious for parse error
4010         messages.  Nevertheless, it is enabled only when `@n' is used in
4011         the grammar, which is a different issue (you can use it in error
4012         message, but not in the grammar per se).  Therefore, there should
4013         be another means to enable it.
4014
4015         * src/getargs.c (getargs): Support `--locations'.
4016         (usage): Report it.
4017         * src/getargs.h (locationsflag): Export it.
4018         * src/lex.c (percent_table): Support `%locations'.
4019         * src/reader.c (yylsp_needed): Remove this variable, now replaced
4020         with `locationsflag'.
4021         * doc/bison.texinfo: Document `--locations' and `%locations'.
4022         Sort the options.
4023         * tests/calc.m4: Test it.
4024
4025         For regularity of the names, replace each
4026         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4027         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4028         In addition replace each `flag' with `_flag'.
4029
4030 2000-10-02  Akim Demaille  <akim@epita.fr>
4031
4032         Also test parse error messages, including with YYERROR_VERBOSE.
4033
4034         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4035         associative).
4036         Use it to check the computations.
4037         Use it to check `nonassoc' is honored.
4038         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4039         `--yyerror-verbose'.
4040         (_AT_CHECK_CALC): Adjust to this option.
4041         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4042
4043 2000-10-02  Akim Demaille  <akim@epita.fr>
4044
4045         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
4046         the latter demonstrates a flaw in the handling of non debugging
4047         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4048         was used in order to simplify:
4049
4050         #if YYDEBUG
4051         if (yydebug)
4052         {
4053         ...
4054         }
4055         #endif
4056
4057         into
4058
4059         if (yydebug)
4060         {
4061         ...
4062         }
4063
4064         unfortunately this leads to a CPP conflict when
4065         `--name-prefix=foo' is used since it produces `#define yydebug
4066         foodebug'.
4067
4068         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4069         (YYDPRINTF): New macro.
4070         Spread its use.
4071         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4072         the bison options.
4073         Also test `--verbose', `--defines' and `--name-prefix'.
4074
4075 2000-10-02  Akim Demaille  <akim@epita.fr>
4076
4077         Improve the readability of the produced parsers.
4078
4079         * src/bison.s1: Formatting changes.
4080         Improve the comment related to the `$' mark.
4081         (yydefault): Don't fall through to `yyresume': `goto' there.
4082         * src/output.c (output_parser): When the `$' is met, skip the end
4083         of its line.
4084         New variable, `number_of_dollar_signs', to check there's exactly
4085         one `$' in the parser skeleton.
4086
4087 2000-10-02  Akim Demaille  <akim@epita.fr>
4088
4089         * lib/xstrdup.c: New file, from the fileutils.
4090         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4091         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4092         instead of strlen + xmalloc + strcpy.
4093         * src/symtab.c (copys): Remove, use xstrdup instead.
4094
4095 2000-10-02  Akim Demaille  <akim@epita.fr>
4096
4097         * src/gram.h (associativity): New enum type which replaces the
4098         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4099         `right_assoc', `left_assoc' and `non_assoc'.
4100         Adjust all dependencies.
4101         * src/reader.c: Formatting changes.
4102         (LTYPESTR): Don't define it, use it as a literal in
4103         `reader_output_yylsp'.
4104         * src/symtab.h (symbol_class): New enum type which replaces the
4105         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4106         `sunknown', `stoken and `snterm'.
4107
4108 2000-10-02  Akim Demaille  <akim@epita.fr>
4109
4110         * src/getargs.c (fixed_outfiles): Rename as...
4111         (yaccflag): for consistency and accuracy.
4112         Adjust dependencies.
4113
4114 2000-10-02  Akim Demaille  <akim@epita.fr>
4115
4116         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4117         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4118         difficult and introduced a lot of core dump.  It turns out that
4119         Bison used an implementation of `xmalloc' based on `calloc', and
4120         at various places it does depend upon the initialization to 0.  I
4121         have not tried to isolate the pertinent places, and all the former
4122         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4123         someone should address this issue.
4124
4125         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4126         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
4127         files.

4137
4138 2000-10-02  Akim Demaille  <akim@epita.fr>
4139
4140         * src/state.h (nstates, final_state, first_state, first_shift)

4219
4220         * src/output.c (token_actions): Introduce a temporary array,

4222         output_short_table.
4223
4224 2000-10-02  Akim Demaille  <akim@epita.fr>
4225
4226         `user_toknums' is output as a `short[]' in `output.c', while it is
4227         defined as a `int[]' in `reader.c'.  For consistency with the
4228         other output tables, `user_toknums' is now defined as a table of
4229         shorts.
4230
4231         * src/reader.c (user_toknums): Be a short table instead of an int
4232         table.

4244         order to get rid of the `static' prototypes.
4245         No longer use `register'.
4246         * src/output.h: New file.
4247         Propagate its inclusion in files explicitly prototyping functions
4248         from output.c.

4259         (initialize_closure, finalize_closure):  Rename as...
4260         (new_closure, free_closure): these.  Adjust dependencies.

4270         inclusion.
4271         Don't define PARAMS.
4272         * src/system.h: Define PARAMS.
4273         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
4274         purpose of config.h.  system.h must not try to fix wrong
4275         definitions in config.h.

4299         * src/getargs.h: New file.
4300         Let all `extern' declarations about getargs.c be replaced with

4438
4439 2000-03-17  Akim Demaille  <akim@epita.fr>
4440
4441         On syntax errors, report the token on which we choked.

4463         copy_comment.  Removed now unused `match', `ended',
4464         `cplus_comment'.
4465         (copy_comment, copy_string): Moved, to be visible from
4466         copy_definition.

4469

4492
4493         Change the handling of @s so that they behave exactly like $s.
4494         There is now a pseudo variable @$ (readble and writable), location
4495         of the lhs of the rule (by default ranging from the location of
4496         the first symbol of the rhs, to the location of the last symbol,
4497         or, if the rhs is empty, YYLLOC).
4498
4499         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4500         yyval.
4501         (yyparse): When providing a default semantic action, provide a
4502         default location action.
4503         (after the $): No longer change `*YYLSP', just stack YYLOC the
4504         same way you stack YYVAL.
4505         * src/reader.c (read_declarations): Use warns.
4506         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4507         (copy_action, case '@'): Likewise.
4508         Use a standard error message, to save useless work from
4509         translators.
4510
4511 2000-03-17  Akim Demaille  <akim@epita.fr>
4512

4530
4531         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4532         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4533         One `#if YYDEBUG' remains, since it uses variables which are
4534         defined only if `YYDEBUG != 0'.
4535
4536 2000-03-16  Akim Demaille  <akim@epita.fr>
4537
4538         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

4560         handled via src/Makefile.am.

4562         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
4563         autoheader.

4568         the proper line number and file name.
4569         (DEFS): Propagate the location of bison library files and of the
4570         locale files.
4571         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4572         builddir.
4573         * acinclude.m4: Remove, replaced by the directory m4.
4574         * m4/Makefile.am (EXTRA_DIST): New variable.
4575         * m4/gettext.m4: New file, from the fileutils.

5262         major changes to files.c.
