  15 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
  16
  17         * data/bison.c++: Replace some direct m4 expansions by constants.  Be

  19         directives around tables only needed for debugging.
  20
  21 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>

  40
  41 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
  42
  43         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
  44         not expanded by m4.
  45
  46 2002-02-05  Akim Demaille  <akim@epita.fr>
  47
  48         * data/bison.c++: Adjust to the M4 back end.
  49         More is certainly needed.
  50
  51 2002-02-05  Akim Demaille  <akim@epita.fr>
  52
  53         Give a try to M4 as a back end.
  54
  55         * lib/readpipe.c: New, from wdiff.
  56         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
  57         BISON_HAIRY.
  58         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
  59         specific values.  Now it is m4 that performs the lookup.
  60         * src/parse-skel.y: Remove.
  61         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
  62         * src/output.c (actions_output, guards_output)
  63         (token_definitions_output): No longer keeps track of the output
  64         line number, hence remove the second argument.
  65         (guards_output): Check against the guard member of a rule, not the
  66         action member.
  67         Adjust callers.
  68         (output_skeleton): Don't look for the skeleton location, let m4 do
  69         that.
  70         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
  71         file will be used.
  72         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
  73         (prepare): Given that for the time being changesyntax is not
  74         usable in M4, rename the muscles using `-' to `_'.
  75         Define `defines_flag', `output_parser_name' and `output_header_name'.
  76         * src/output.h (actions_output, guards_output)
  77         (token_definitions_output): Adjust prototypes.
  78         * src/scan-skel.l: Instead of scanning the skeletons, it now
  79         processes the output of m4: `__oline__' and `#output'.
  80         * data/bison.simple: Adjust to be used by M4(sugar).
  81         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
  82         to date.
  83         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
  84         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
  85         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
  86         shamelessly stolen from CVS Autoconf.
  87
  88 2002-02-05  Akim Demaille  <akim@epita.fr>
  89
  90         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
  91         * configure.in: Check for the declarations of free and malloc.
  92         * src/muscle_tab.c: Adjust.
  93
  94 2002-02-05  Akim Demaille  <akim@epita.fr>
  95
  96         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
  97         which have no values.
  98
  99 2002-02-05  Akim Demaille  <akim@epita.fr>
 100
 101         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
 102         * data/: here.
 103
 104 2002-01-29  Paul Eggert  <eggert@twinsun.com>
 105
 106         * src/bison.simple (YYSIZE_T): Do not define merely because
 107         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 108         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 109
 110 2002-01-27  Akim Demaille  <akim@epita.fr>
 111
 112         Fix `%nonassoc and eof'.
 113
 114         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
 115         which were not properly copied!  Replace
 116         memcpy (res->errs, src->errs, src->nerrs);
 117         with
 118         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
 119         !!!
 120         * tests/regression.at (%nonassoc and eof): Adjust to newest
 121         Autotest: `.' is not in the PATH.
 122
 123 2002-01-27  Akim Demaille  <akim@epita.fr>
 124
 125         * tests/sets.at (AT_EXTRACT_SETS): New.
 126         (Nullable): Use it.
 127         (Firsts): New.
 128
 129 2002-01-26  Akim Demaille  <akim@epita.fr>
 130
 131         * tests/actions.at, tests/calc.at, tests/headers.at,
 132         * tests/torture.at: Adjust to the newest Autotest which no longer
 133         forces `.' in the PATH.
 134
 135 2002-01-25  Akim Demaille  <akim@epita.fr>
 136
 137         * tests/regression.at (%nonassoc and eof): New.
 138         Suggested by Robert Anisko.
 139
 140 2002-01-24  Akim Demaille  <akim@epita.fr>
 141
 142         Bison dumps core when trying to complain about broken input files.
 143         Reported by Cris van Pelt.
 144
 145         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
 146         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
 147         into...
 148         (Invalid inputs): Strengthen: exercise parse_percent_token.
 149
 150 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
 151
 152         * src/Makefile.am: Add bison.c++.
 153         * src/bison.c++: New skeleton.
 154
 155 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
 156
 157         * po/it.po: New.
 158
 159 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
 160
 161         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
 162
 163 2002-01-20  Marc Autret  <marc@gnu.org>
 164
 165         * src/files.c (compute_output_file_names): Fix
 166
 167 2002-01-20  Marc Autret  <marc@gnu.org>
 168
 169         * tests/output.at: New test.
 170         * src/files.c (compute_base_names): Don't map extensions when
 171         the YACC flag is set, use defaults.
 172         Reported by Evgeny Stambulchik.
 173
 174 2002-01-20  Marc Autret  <marc@gnu.org>
 175
 176         * src/system.h: Need to define __attribute__ away for non-GCC
 177         compilers as well (i.e. the vendor C compiler).
 178         Suggested by Albert Chin-A-Young.
 179
 180 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
 181
 182         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
 183         canonical definition.
 184         * src/system.h: Use the canonical definition for PARAMS (avoids
 185         a conflict with the macro from lib/hash.h).
 186
 187 2002-01-11  Akim Demaille  <akim@epita.fr>
 188
 189         * configure.in: Use AC_FUNC_STRNLEN.
 190         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
 191
 192 2002-01-09  Akim Demaille  <akim@epita.fr>
 193
 194         * src/files.c, src/files.h (output_infix): New.
 195         (tab_extension): Remove.
 196         (compute_base_names): Compute the former, drop the latter.
 197         * src/output.c (prepare): Insert the muscles `output-infix', and
 198         `output-suffix'.
 199         * src/parse-skel.y (string, string.1): New.
 200         (section.header): Use it.
 201         (section.yacc): Remove.
 202         (prefix): Remove too.
 203         * src/scan-skel.l: Adjust.
 204         * src/bison.simple, src/bison.hairy: Adjust.
 205
 206 2002-01-09  Akim Demaille  <akim@epita.fr>
 207
 208         * configure.in (WERROR_CFLAGS): Compute it.
 209         * src/Makefile.am (CFLAGS): Pass it.
 210         * tests/atlocal.in (CFLAGS): Idem.
 211         * src/files.c: Fix a few warnings.
 212         (get_extension_index): Remove, unused.
 213
 214 2002-01-08  Akim Demaille  <akim@epita.fr>
 215
 216         * src/getargs.c (AS_FILE_NAME): New.
 217         (getargs): Use it to convert DOSish file names.
 218         * src/files.c (base_name): Rename as full_base_name to avoid
 219         clashes with `base_name ()'.
 220         (filename_split): New.
 221         (compute_base_names): N-th rewrite, using filename_split.
 222
 223 2002-01-08  Akim Demaille  <akim@epita.fr>
 224
 225         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
 226         New, stolen from the Fileutils 4.1.
 227         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
 228         * configure.in: Check for the presence of memrchr, and of its
 229         prototype.
 230
 231 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
 232
 233         * lib/hash.h (__P): Added definition for this macro.
 234         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
 235         BUILT_SOURCES, to ensure they are generated first.
 236         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
 237         %error-verbose to allow bootstrapping with bison 1.30x.
 238
 239 2002-01-06  Akim Demaille  <akim@epita.fr>
 240
 241         * src/reader.c (parse_braces): Don't fetch the next char, the
 242         convention is to fetch on entry.
 243         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
 244         'switch' without a following semicolon.
 245         * tests/regression.at (braces parsing): New.
 246
 247 2002-01-06  Akim Demaille  <akim@epita.fr>
 248
 249         Bison is dead wrong in its RR conflict reports.
 250
 251         * tests/torture.at (GNU Cim Grammar): New.
 252         * src/conflicts.c (count_rr_conflicts): Fix.
 253
 254 2002-01-06  Akim Demaille  <akim@epita.fr>
 255
 256         Creating package.m4 from configure.ac causes too many problems.
 257
 258         * tests/Makefile.am (package.m4): Create it by hand,
 259         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
 260
 261 2002-01-06  Akim Demaille  <akim@epita.fr>
 262
 263         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
 264         skeleton.h.
 265
 266 2002-01-04  Paul Eggert  <eggert@twinsun.com>
 267
 268         * doc/bison.texinfo (Debugging):
 269         Remove YYSTDERR; it's no longer defined or used.
 270         Also, s/cstdio.h/cstdio/.
 271
 272 2002-01-03  Akim Demaille  <akim@epita.fr>
 273
 274         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
 275
 276 2002-01-03  Akim Demaille  <akim@epita.fr>
 277
 278         * src/parse-skel.y (process_skeleton): Don't bind the parser's
 279         tracing code to --trace, wait for a better --trace option, with
 280         args.
 281
 282 2002-01-03  Akim Demaille  <akim@epita.fr>
 283
 284         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
 285         The ISO C++ standard is extremely clear about it: stderr is
 286         considered a macro, not a regular symbol (see table 94 `Header
 287         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
 288         Therefore std:: does not apply to it.  It still does with fprintf.
 289         Also, s/cstdio.h/cstdio/.
 290
 291 2002-01-03  Akim Demaille  <akim@epita.fr>
 292
 293         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
 294         for non system headers.
 295
 296 2002-01-02  Akim Demaille  <akim@epita.fr>
 297
 298         Equip the skeleton chain with location tracking, runtime trace,
 299         pure parser and scanner.
 300
 301         * src/parse-skel.y: Request a pure parser, locations, and prefix
 302         renaming.
 303         (%union): Having several members with the same type does not help
 304         type mismatches, simplify.
 305         (YYPRINT, yyprint): New.
 306         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
 307         (skel_error): this.
 308         Handle locations.
 309         * src/scan-skel.l: Adjust to these changes.
 310         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
 311         (LOCATION_PRINT, skel_control_t): New.
 312
 313 2001-12-30  Akim Demaille  <akim@epita.fr>
 314
 315         * src/parse-skel.y: Get rid of the shift/reduce conflict:
 316         replace `gb' with BLANKS.
 317         * src/scan-skel.l: Adjust.
 318
 319 2001-12-30  Akim Demaille  <akim@epita.fr>
 320
 321         * src/system.h: We don't need nor want bcopy.
 322         Throw away MS-DOS crap: we don't need getpid.
 323         * configure.in: We don't need strndup.  It was even causing
 324         problems: because Flex includes the headers *before* us,
 325         _GNU_SOURCE is not defined by config.h, and therefore strndup was
 326         not visible.
 327         * lib/xstrndup.c: New.
 328         * src/scan-skel.l: Use it.
 329         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
 330         * src/parse-skel.y: Use %directives instead of #defines.
 331
 332 2001-12-30  Akim Demaille  <akim@epita.fr>
 333
 334         * src/skeleton.h: New.
 335         * src/output.c (output_parser, output_master_parser): Remove, dead
 336         code.
 337         * src/output.h (get_lines_number, actions_output, guards_output)
 338         (token_definitions_output): Prototype them.
 339         * src/parse-skel.y: Add the license notice.
 340         Include output.h and skeleton.h.
 341         (process_skeleton): Returns void, and takes a single parameter.
 342         * src/scan-skel.l: Add the license notice.
 343         Include skeleton.h.
 344         Don't use %option yylineno: it seems that then Flex imagines
 345         REJECT has been used, and therefore it won't reallocate its
 346         buffers (which makes no other sense to me than a bug).  It results
 347         in warnings for `unused: yy_flex_realloc'.
 348
 349 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
 350
 351         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 352         (MUSCLE_INSERT_PREFIX): ...to there.
 353         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 354         (MUSCLE_INSERT_PREFIX): Move from here...
 355
 356         * src/bison.hairy: Add a section directive.  Put braces around muscle
 357         names.  This parser skeleton is still broken, but Bison should not
 358         choke on a bad muscle 'syntax'.
 359         * src/bison.simple: Add a section directive.  Put braces around muscle
 360         names.
 361
 362         * src/files.h (strsuffix, stringappend): Add declarations.
 363         (tab_extension): Add declaration.
 364         (short_base_name): Add declaration.
 365
 366         * src/files.c (strsuffix, stringappend): No longer static.  These
 367         functions are used in the skeleton parser.
 368         (tab_extension): New.
 369         (compute_base_names): Use the computations done in this function
 370         to guess if the generated parsers should have '.tab' in their
 371         names.
 372         (short_base_name): No longer static.
 373
 374         * src/output.c (output_skeleton): New.
 375         (output): Disable call to output_master_parser, and give a try to
 376         a new skeleton handling system.
 377         (guards_output, actions_output): No longer static.
 378         (token_definitions_output, get_lines_number): No longer static.
 379
 380         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
 381
 382         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
 383         parse-skel.y.
 384
 385         * src/parse-skel.y: New file.
 386         * src/scan-skel.l: New file.
 387
 388 2001-12-29  Akim Demaille  <akim@epita.fr>
 389
 390         %name-prefix is broken.
 391
 392         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
 393         Adjust all dependencies.
 394         * tests/headers.at (export YYLTYPE): Strengthen this test: use
 395         %name-prefix.
 396
 397         Renaming yylval but not yylloc is not consistent.  Now we do.
 398
 399         * src/bison.simple: Prefix yylloc if used.
 400         * doc/bison.texinfo (Decl Summary): Document that.
 401
 402 2001-12-29  Akim Demaille  <akim@epita.fr>
 403
 404         * doc/bison.texinfo: Promote `%long-directive' over
 405         `%long_directive'.
 406         Remove all references to fixed-output-files, yacc is enough.
 407
 408 2001-12-29  Akim Demaille  <akim@epita.fr>
 409
 410         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
 411         user prologue.  These are defaults.
 412         * tests/actions.at (Mid-rule actions): Make sure the user can
 413         define YYDEBUG and YYERROR_VERBOSE.
 414
 415 2001-12-29  Akim Demaille  <akim@epita.fr>
 416
 417         * src/output.c (header_output): Don't forget to export YYLTYPE and
 418         yylloc.
 419         * tests/headers.at (export YYLTYPE): New, make sure it does.
 420         * tests/regression.at (%union and --defines, Invalid CPP headers):
 421         Move to...
 422         * tests/headers.at: here.
 423
 424 2001-12-29  Akim Demaille  <akim@epita.fr>
 425
 426         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
 427
 428 2001-12-29  Akim Demaille  <akim@epita.fr>
 429
 430         * tests/actions.at (Mid-rule actions): Output on a single line
 431         instead of several.
 432
 433 2001-12-29  Akim Demaille  <akim@epita.fr>
 434
 435         * doc/bison.texinfo: Formatting changes.
 436
 437 2001-12-29  Akim Demaille  <akim@epita.fr>
 438
 439         Don't store the token defs in a muscle, just be ready to output it
 440         on command.  Now possible via `symbols'.  Fixes a memory leak.
 441
 442         * src/output.c (token_definitions_output): New.
 443         (output_parser, header_output): Use it.
 444         * src/reader.c (symbols_save): Remove.
 445
 446 2001-12-29  Akim Demaille  <akim@epita.fr>
 447
 448         * src/bison.simple: Do not provide a default for YYSTYPE and
 449         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
 450         default.
 451
 452 2001-12-29  Akim Demaille  <akim@epita.fr>
 453
 454         Mid-rule actions are simply... ignored!
 455
 456         * src/reader.c (readgram): Be sure to attach mid-rule actions to
 457         the empty-rule associated to the dummy symbol, not to the host
 458         rule.
 459         * tests/actions.at (Mid-rule actions): New.
 460
 461 2001-12-29  Akim Demaille  <akim@epita.fr>
 462
 463         Memory leak.
 464
 465         * src/reader.c (reader): Free grammar.
 466
 467 2001-12-29  Akim Demaille  <akim@epita.fr>
 468
 469         Memory leak.
 470
 471         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
 472         since it allocates it for each state, although only one is needed.
 473         (allocate_storage): Do it here.
 474
 475 2001-12-29  Akim Demaille  <akim@epita.fr>
 476
 477         * src/options.h, src/options.c (create_long_option_table): Rename
 478         as...
 479         (long_option_table_new): this, with a clearer prototype.
 480         (percent_table): Remove, unused,
 481         * src/getargs.c (getargs): Adjust.
 482
 483 2001-12-29  Akim Demaille  <akim@epita.fr>
 484
 485         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
 486         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 487         as states.
 488
 489 2001-12-29  Akim Demaille  <akim@epita.fr>
 490
 491         * src/lalr.c (build_relations): Rename `states' as `states1'.
 492         Sorry, I don't understand exactly what it is, no better name...
 493
 494 2001-12-29  Akim Demaille  <akim@epita.fr>
 495
 496         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 497         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 498         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 499         as rules.
 500
 501 2001-12-29  Akim Demaille  <akim@epita.fr>
 502
 503         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 504         ago.
 505
 506 2001-12-29  Akim Demaille  <akim@epita.fr>
 507
 508         * src/reader.c, src/reader.h (user_toknums): Remove.
 509         Adjust all users to use symbols[i]->user_token_number.
 510
 511 2001-12-29  Akim Demaille  <akim@epita.fr>
 512
 513         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 514         Adjust all users to use symbols[i]->prec or ->assoc.
 515
 516 2001-12-29  Akim Demaille  <akim@epita.fr>
 517
 518         * src/reader.c, src/reader.h (tags): Remove.
 519         Adjust all users to use symbols[i]->tag.
 520
 521 2001-12-29  Akim Demaille  <akim@epita.fr>
 522
 523         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 524         and rule_table.
 525         * src/reader.c (packsymbols): Fill this table.
 526         Drop sprec.
 527         * src/conflicts.c (resolve_sr_conflict): Adjust.
 528         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 529         single table.
 530         Use symbols[i]->tag instead of tags[i].
 531
 532 2001-12-29  Akim Demaille  <akim@epita.fr>
 533
 534         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 535         In addition, put a comment in there, to replace...
 536         * tests/regression.at (%union and C comments): Remove.
 537
 538 2001-12-29  Akim Demaille  <akim@epita.fr>
 539
 540         * tests/regression.at (Web2c Actions): Blindly move the actual
 541         output as expected output.  The contents *seem* right to me, but I
 542         can't pretend reading perfectly parser tables...  Nonetheless, all
 543         the other tests pass correctly, the table look OK, even though the
 544         presence of `$axiom' is to be noted: AFAICS it is useless (but
 545         harmless).
 546
 547 2001-12-29  Akim Demaille  <akim@epita.fr>
 548
 549         * src/reader.c (readgram): Don't add the rule 0 if there were no
 550         rules read.  In other words, add it _after_ having performed
 551         grammar sanity checks.
 552         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 553
 554 2001-12-29  Akim Demaille  <akim@epita.fr>
 555
 556         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 557         visible, and some states have now a different number.
 558
 559 2001-12-29  Akim Demaille  <akim@epita.fr>
 560
 561         * src/reader.c (readgram): Bind the initial rule's lineno to that
 562         of the first rule.
 563         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 564         (Solved SR Conflicts): Adjust rule 0's line number.
 565
 566 2001-12-29  Akim Demaille  <akim@epita.fr>
 567
 568         Fix the `GAWK Grammar' failure.
 569
 570         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 571         the reductions of the first state which was mistakenly confused
 572         with the final state because precisely final_state was initialized
 573         to 0.
 574         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 575         now noticed by Bison.
 576         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 577         have a reduction on $default.
 578
 579 2001-12-29  Akim Demaille  <akim@epita.fr>
 580
 581         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 582         rule line numbers.
 583         * src/closure.c (print_closure): Likewise.
 584         * src/derives.c (print_derives): Likewise.
 585         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 586         now.
 587
 588 2001-12-29  Akim Demaille  <akim@epita.fr>
 589
 590         * src/lalr.c (lookaheads_print): New.
 591         (lalr): Call it when --trace-flag.
 592         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 593         are dumped.
 594
 595 2001-12-29  Akim Demaille  <akim@epita.fr>
 596
 597         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 598         when walking through ritem, even via rule->rhs.
 599         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 600         (useful_production, useless_nonterminals): Likewise.
 601         (reduce_grammar_tables): Likewise, plus update nritems.
 602         * src/nullable.c (set_nullable): Likewise.
 603         * src/lalr.c (build_relations): Likewise.
 604         * tests/sets.at (Nullable): Adjust.
 605         Fortunately, now, the $axiom is no longer nullable.
 606
 607 2001-12-29  Akim Demaille  <akim@epita.fr>
 608
 609         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 610         the 0-sentinel.
 611         * src/gram.c (ritem_longest_rhs): Likewise.
 612         * src/reduce.c (nonterminals_reduce): Likewise.
 613         * src/print_graph.c (print_graph): Likewise.
 614         * src/output.c (output_rule_data): Likewise.
 615         * src/nullable.c (set_nullable):  Likewise.
 616
 617 2001-12-29  Akim Demaille  <akim@epita.fr>
 618
 619         * src/output.c: Comment changes.
 620
 621 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 622
 623         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 624         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 625         Sparc, as they were causing more porting problems than the
 626         (minor) performance improvement was worth.
 627
 628         Also, catch up with 1.31's YYSTD.
 629
 630 2001-12-27  Akim Demaille  <akim@epita.fr>
 631
 632         * src/output.c (output_gram): Rely on nritems, not the
 633         0-sentinel.  See below.
 634         Use -1 as separator, not 0.
 635         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 636         Rely on -1 as separator in yyrhs, instead of 0.
 637         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 638         twice `Now at end of input', therefore there are two lines less to
 639         expect.
 640
 641 2001-12-27  Akim Demaille  <akim@epita.fr>
 642
 643         * tests/regression.at (Unresolved SR Conflicts):
 644         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 645         below.
 646
 647 2001-12-27  Akim Demaille  <akim@epita.fr>
 648
 649         * src/LR0.c (new_state): Recognize the final state by the fact it
 650         is reached by eoftoken.
 651         (insert_start_shifting_state, insert_eof_shifting_state)
 652         (insert_accepting_state, augment_automaton): Remove, since now
 653         these states are automatically computed from the initial state.
 654         (generate_states): Adjust.
 655         * src/print.c: When reporting a rule number to the user, substract
 656         1, so that the axiom rule is rule 0, and the first user rule is 1.
 657         * src/reduce.c: Likewise.
 658         * src/print_graph.c (print_core): For the time being, just as for
 659         the report, depend upon --trace-flags to dump the full set of
 660         items.
 661         * src/reader.c (readgram): Once the grammar read, insert the rule
 662         0: `$axiom: START-SYMBOL $'.
 663         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 664         number of the states has changed (the final state is no longer
 665         necessarily the last), catch up.
 666
 667 2001-12-27  Akim Demaille  <akim@epita.fr>
 668
 669         Try to make the use of the eoftoken valid.  Given that its value
 670         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 671         is used instead of > 0 where appropriate, (ii), depend upon nritems
 672         instead of the 0-sentinel.
 673
 674         * src/gram.h, src/gram.c (nritems): New.
 675         Expected to be duplication of nitems, but for the time being...
 676         * src/reader.c (packgram): Assert nritems and nitems are equal.
 677         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 678         * src/closure.c (print_closure, print_fderives): Likewise.
 679         * src/gram.c (ritem_print): Likewise.
 680         * src/print.c (print_core, print_grammar): Likewise.
 681         * src/print_graph.c: Likewise.
 682
 683 2001-12-27  Akim Demaille  <akim@epita.fr>
 684
 685         * src/main.c (main): If there are complains after grammar
 686         reductions, then output the report anyway if requested, then die.
 687         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 688         * src/reader.c (eoftoken): New.
 689         (parse_token_decl): If the token being defined has value `0', it
 690         is the eoftoken.
 691         (packsymbols): No longer hack `tags' to insert `$' by hand.
 692         Be sure to preserve the value of the eoftoken.
 693         (reader): Make sure eoftoken is defined.
 694         Initialize nsyms to 0: now eoftoken is created just like the others.
 695         * src/print.c (print_grammar): Don't special case the eof token.
 696         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 697         lie anyway, albeit pleasant.
 698         * tests/calc.at: Exercise error messages with eoftoken.
 699         Change the grammar so that empty input is invalid.
 700         Adjust expectations.
 701         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 702
 703 2001-12-27  Akim Demaille  <akim@epita.fr>
 704
 705         * configure.in: Check the protos of strchr ans strspn.
 706         Replace strchr if needed.
 707         * src/system.h: Provide the protos of strchr, strspn and memchr if
 708         missing.
 709         * lib/strchr.c: New.
 710         * src/reader.c (symbols_save): Use strchr.
 711
 712 2001-12-27  Akim Demaille  <akim@epita.fr>
 713
 714         * src/print.c, src/print_graph.c (escape): New.
 715         Use it to quote the TAGS outputs.
 716         * src/print_graph.c (print_state): Now errors are in red, and
 717         reductions in green.
 718         Prefer high to wide: output the state number on a line of its own.
 719
 720 2001-12-27  Akim Demaille  <akim@epita.fr>
 721
 722         * src/state.h, src/state.c (reductions_new): New.
 723         * src/LR0.c (set_state_table): Let all the states have a
 724         `reductions', even if reduced to 0.
 725         (save_reductions): Adjust.
 726         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 727         * src/print.c (print_reductions, print_actions): Adjust.
 728         * src/output.c (action_row): Adjust.
 729
 730 2001-12-27  Akim Demaille  <akim@epita.fr>
 731
 732         * src/state.h, src/state.c (errs_new, errs_dup): New.
 733         * src/LR0.c (set_state_table): Let all the states have an errs,
 734         even if reduced to 0.
 735         * src/print.c (print_errs, print_reductions): Adjust.
 736         * src/output.c (output_actions, action_row): Adjust.
 737         * src/conflicts.c (resolve_sr_conflict): Adjust.

 739 2001-12-27  Akim Demaille  <akim@epita.fr>
 740
 741         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 742
 743 2001-12-27  Akim Demaille  <akim@epita.fr>
 744
 745         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 746         * src/print.c: here.
 747         (lookaheadset, shiftset): New, used as additional storage by
 748         print_reductions.
 749         (print_results): Adjust.
 750         (print_shifts, print_gotos, print_errs): New, extracted from...
 751         (print_actions): here.
 752         * src/print_graph.c (print_actions): Remove dead code.
 753
 754 2001-12-27  Akim Demaille  <akim@epita.fr>
 755
 756         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 757         `$n' and `@n'.
 758
 759 2001-12-27  Akim Demaille  <akim@epita.fr>
 760
 761         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 762         (build_relations): Adjust.
 763
 764 2001-12-27  Akim Demaille  <akim@epita.fr>
 765
 766         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 767         duplication.
 768
 769 2001-12-27  Akim Demaille  <akim@epita.fr>
 770
 771         * src/reader.c (packgram): Catch nitems overflows.
 772
 773 2001-12-27  Akim Demaille  <akim@epita.fr>
 774
 775         * src/files.c, src/files.h (guard_obstack): Remove.
 776         * src/output.c (output): Adjust.
 777         * src/reader.c (parse_braces): New, factoring...
 778         (copy_action, copy_guard): these two which are renamed as...
 779         (parse_action, parse_guard): these.
 780         As a voluntary consequence, using braces around guards is now
 781         mandatory.
 782
 783 2001-12-27  Akim Demaille  <akim@epita.fr>
 784
 785         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 786         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 787         members.
 788         (symbol_list_new): Adjust.
 789         (copy_action): action_line is the first line, not the last.
 790         (copy_guard): Just as for actions, store the `action' only, not
 791         the switch/case/break flesh.
 792         Don't parse the user action that might follow the guard, let...
 793         (readgram): do it, i.e., now, there can be an action after a
 794         guard.
 795         In other words the guard is just explicitly optional.
 796         (packgram): Adjust.
 797         * src/output.c (guards_output): New.
 798         (output_parser): Call it when needed.
 799         (output): Also free the guard and attrs obstacks.
 800         * src/files.c, src/files.h (obstack_save): Remove.
 801         (output_files): Remove.
 802         As a result, if one needs the former `.act' file, using an
 803         appropriate skeleton which requires actions and guards is now
 804         required.
 805         * src/main.c (main): Adjust.
 806         * tests/semantic.at: New.
 807         * tests/regression.at: Use `input.y' as input file name.
 808         Avoid 8+3 problems by requiring input.c when the test needs the
 809         parser.
 810
 811 2001-12-27  Akim Demaille  <akim@epita.fr>
 812
 813         * src/reader.c (symbol_list_new): Be sure to initialize all the
 814         fields.
 815
 816 2001-12-27  Akim Demaille  <akim@epita.fr>
 817
 818         All the hacks using a final pseudo state are now useless.
 819
 820         * src/LR0.c (set_state_table): state_table holds exactly nstates.
 821         * src/lalr.c (nLA): New.
 822         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
 823         instead of lookaheadsp from the pseudo state (nstate + 1).
 824
 825 2001-12-27  Akim Demaille  <akim@epita.fr>
 826
 827         * src/output.c (action_row, token_actions): Use a state_t instead
 828         of a integer, and nlookaheads instead of the following state's
 829         lookaheadsp.
 830
 831 2001-12-27  Akim Demaille  <akim@epita.fr>
 832
 833         * src/conflicts.c (log_resolution, flush_shift)
 834         (resolve_sr_conflict, set_conflicts, solve_conflicts)
 835         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
 836         (conflicts_print, print_reductions): Use a state_t instead of an
 837         integer when referring to a state.
 838         As much as possible, depend upon nlookaheads, instead of the
 839         `lookaheadsp' member of the following state (since lookaheads of
 840         successive states are successive, the difference between state n + 1
 841         and n served as the number of lookaheads for state n).
 842         * src/lalr.c (add_lookback_edge): Likewise.
 843         * src/print.c (print_core, print_actions, print_state)
 844         (print_results): Likewise.
 845         * src/print_graph.c (print_core, print_actions, print_state)
 846         (print_graph): Likewise.
 847         * src/conflicts.h: Adjust.
 848
 849 2001-12-27  Akim Demaille  <akim@epita.fr>
 850
 851         * src/bison.hairy: Formatting/comment changes.
 852         ANSIfy.
 853         Remove `register' indications.
 854         Add plenty of `static'.
 855
 856 2001-12-27  Akim Demaille  <akim@epita.fr>
 857
 858         * src/output.c (prepare): Drop the muscle `ntbase' which
 859         duplicates ntokens.
 860         * src/bison.simple: Formatting/comment changes.
 861         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
 862         is an undocumented synonym.
 863
 864 2001-12-22  Akim Demaille  <akim@epita.fr>
 865
 866         * src/output.c (output_table_data): Change the prototype to use
 867         `int' for array ranges: some invocations do pass an int, not a
 868         short.
 869         Reported by Wayne Green.
 870
 871 2001-12-22  Akim Demaille  <akim@epita.fr>
 872
 873         Some actions of web2c.y are improperly triggered.
 874         Reported by Mike Castle.
 875
 876         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
 877         * tests/regression.at (Web2c): Rename as...
 878         (Web2c Report): this.
 879         (Web2c Actions): New.
 880
 881 2001-12-22  Akim Demaille  <akim@epita.fr>
 882
 883         Reductions in web2c.y are improperly reported.

 887         * tests/regression.at (Web2c): New.
 888
 889 2001-12-18  Akim Demaille  <akim@epita.fr>
 890
 891         Some host fail on `assert (!"foo")', which expands to
 892         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
 893         Reported by Nelson Beebee.
 894
 895         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
 896         `#define it_succeeded 0' and `assert (it_succeeded)'.
 897
 898 2001-12-17  Marc Autret  <autret_m@epita.fr>
 899
 900         * src/bison.simple: Don't hard code the skeleton line and filename.
 901         * src/output.c (output_parser): Rename 'line' as 'output_line'.
 902         New line counter 'skeleton_line' (skeleton-line muscle).
 903
 904 2001-12-17  Paul Eggert  <eggert@twinsun.com>
 905
 906         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
 907         YYDEBUG must be defined to a nonzero value.
 908
 909         * src/bison.simple (yytname): Do not assume that the user defines
 910         YYDEBUG to a properly parenthesized expression.
 911
 912 2001-12-17  Akim Demaille  <akim@epita.fr>
 913
 914         * src/state.h (state_t): Rename lookaheads as lookaheadsp.

 918         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
 919         state.
 920
 921 2001-12-17  Akim Demaille  <akim@epita.fr>
 922
 923         * src/files.h, src/files.c (open_files, close_files): Remove.
 924         * src/main.c (main): Don't open/close files, nor invoke lex_free,
 925         let...

 927
 928 2001-12-17  Akim Demaille  <akim@epita.fr>

 931
 932 2001-12-17  Akim Demaille  <akim@epita.fr>
 933
 934         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
 935         (flush_reduce): New.
 936         (resolve_sr_conflict): Adjust.
 937
 938 2001-12-17  Akim Demaille  <akim@epita.fr>
 939
 940         * src/output.c (output_obstack): Be static and rename as...
 941         (format_obstack): this, to avoid any confusion with files.c's
 942         output_obstack.
 943         * src/reader.h (muscle_obstack): Move to...
 944         * src/output.h: here, since it's defined in output.c.
 945
 946 2001-12-17  Akim Demaille  <akim@epita.fr>
 947
 948         * src/output.c (action_row, save_column, default_goto)

 955
 956 2001-12-17  Akim Demaille  <akim@epita.fr>
 957
 958         * src/files.c (output_files): Free the output_obstack.

 964 2001-12-16  Marc Autret  <autret_m@epita.fr>
 965
 966         * src/output.c (actions_output): Fix. When we use %no-lines,
 967         there is one less line per action.
 968
 969 2001-12-16  Marc Autret  <autret_m@epita.fr>
 970
 971         * src/bison.simple: Remove a useless #line directive.
 972         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
 973         * src/output.c (get_lines_number): New.
 974         (output_parser): Adjust, now takes care about the lines of a
 975         output muscles.
 976         Fix line numbering.
 977         (actions_output): Computes the number of lines taken by actions.
 978         (output_master_parser): Insert new skeleton which is the name of
 979         the output parser file name.
 980
 981 2001-12-15  Marc Autret  <autret_m@epita.fr>
 982
 983         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.

 989 2001-12-15  Akim Demaille  <akim@epita.fr>
 990
 991         Make `make distcheck' work.
 992
 993         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
 994         system.h which uses libgettext.h.
 995
 996 2001-12-15  Akim Demaille  <akim@epita.fr>
 997
 998         * src/nullable.c (set_nullable): Useless rules must be skipped,
 999         otherwise, since we range over their symbols, we might look at a
1000         nonterminal which no longer ``exists'', i.e., it is not counted in
1001         `nvars', hence we overflow our arrays.
1002
1003 2001-12-15  Akim Demaille  <akim@epita.fr>
1004
1005         The header can also be produced directly, without any obstack!
1006         Yahoo!
1007
1008         * src/files.c, src/files.h (defines_obstack): Remove.
1009         (compute_header_macro): Global.
1010         (defines_obstack_save): Remove.
1011         * src/reader.c (parse_union_decl): No longer output to
1012         defines_obstack: its content can be found in the `stype' muscle
1013         anyway.
1014         (output_token_translations): Merge into...
1015         (symbols_output): this.

1022 2001-12-15  Akim Demaille  <akim@epita.fr>
1023
1024         * src/reader.c (parse_union_decl): Instead of handling two obstack
1025         simultaneously, use one to define the `stype' muscle, and use the
1026         value of the latter to fill defines_obstack.
1027         (copy_comment): Remove.
1028         (copy_comment2): Work for a single obstack.
1029         Rename as...

1032 2001-12-15  Akim Demaille  <akim@epita.fr>

1036
1037 2001-12-15  Akim Demaille  <akim@epita.fr>
1038
1039         Still making progress in separating Bison into (i) input, (ii)
1040         process, (iii) output: now we can directly output the parser file
1041         without using table_obstack at all.
1042
1043         * src/files.c, src/files.h (table_obstack): Bye bye.
1044         (parser_file_name): New.
1045         * src/files.c (compute_output_file_names): Compute it.
1046         * src/output.c (actions_output, output_parser)
1047         (output_master_parser): To a file instead of an obstack.
1048
1049 2001-12-15  Akim Demaille  <akim@epita.fr>
1050
1051         Attach actions to rules, instead of pre-outputting them to
1052         actions_obstack.
1053
1054         * src/gram.h (rule_t): action and action_line are new members.
1055         * src/reader.c (symbol_list): Likewise.
1056         (copy_action): Save the actions within the rule.
1057         (packgram): Save them in rule_table.
1058         * src/output.c (actions_output): New.
1059         (output_parser): Use it on `%%actions'.
1060         (output_rule_data): Don't free rule_table.
1061         (output): Do it.
1062         (prepare): Don't save the `action' muscle.
1063         * src/bison.simple: s/%%action/%%actions/.
1064
1065 2001-12-15  Akim Demaille  <akim@epita.fr>
1066
1067         * src/reader.c (copy_action): When --yacc, don't append a `;'
1068         to the user action: let it fail if lacking.
1069         Suggested by Arnold Robbins and Tom Tromey.
1070
1071 2001-12-14  Akim Demaille  <akim@epita.fr>
1072
1073         * src/lex.c (literalchar): Simply return the char you decoded, non
1074         longer mess around with obstacks and int pointers.
1075         Adjust all callers.
1076
1077 2001-12-14  Akim Demaille  <akim@epita.fr>
1078
1079         * src/lex.c (literalchar): Don't escape the special characters,
1080         just decode them, and keep them as char (before, eol was output as
1081         the 2 char string `\n' etc.).
1082         * src/output.c (output_rule_data): Use quotearg to output the
1083         token strings.
1084
1085 2001-12-13  Paul Eggert  <eggert@twinsun.com>
1086
1087         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1088         Do not infringe on the global user namespace when using C++.
1089         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1090         All uses of `fprintf' and `stderr' changed.
1091
1092         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1093
1094 2001-12-13  Akim Demaille  <akim@epita.fr>
1095
1096         The computation of nullable is broken: it doesn't handle empty
1097         RHS's properly.
1098
1099         * tests/torture.at (GNU AWK Grammar): New.
1100         * tests/sets.at (Nullable): New.
1101         * src/nullable.c (set_nullable): Instead of blindly looping over
1102         `ritems', loop over the rules, and then over their rhs's.
1103
1104         Work around Autotest bugs.
1105
1106         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1107         frame, because Autotest understand lines starting with a `+' as
1108         traces from the shell.  Then, they are not processed properly.
1109         Admittedly an Autotest bug, but we don't have time to wait for
1110         Autotest to catch up.
1111         * tests/regression.at (Broken Closure): Adjust to the new table
1112         frames.
1113         Move to...
1114         * tests/sets.at: here.
1115
1116 2001-12-13  Akim Demaille  <akim@epita.fr>
1117
1118         * src/closure.c (closure): Use nrules instead of playing tricks
1119         with BITS_PER_WORD.
1120
1121 2001-12-13  Akim Demaille  <akim@epita.fr>
1122
1123         * src/print.c (print_actions): Output the handling of `$' as the
1124         traces do: shifting the token EOF.  Before EOF was treated as a
1125         nonterminal.
1126         * tests/regression.at: Adjust some tests.
1127         * src/print_graph.c (print_core): Complete the set of items via
1128         closure.  The next-to-final and final states are still unsatisfying,
1129         but that's to be addressed elsewhere.
1130         No longer output the rule numbers, but do output the state number.
1131         A single loop for the shifts + gotos is enough, but picked a
1132         distinct color for each.
1133         (print_graph): Initialize and finalize closure.
1134
1135 2001-12-13  Akim Demaille  <akim@epita.fr>
1136
1137         * src/reader.c (readgram): Remove dead code, an strip useless
1138         braces.
1139         (get_type): Remove, unused.
1140
1141 2001-12-12  Akim Demaille  <akim@epita.fr>
1142
1143         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1144         on that of lib/error.c.
1145
1146 2001-12-12  Akim Demaille  <akim@epita.fr>
1147
1148         Some hosts don't like `/' in includes.
1149
1150         * src/system.h: Include libgettext.h without qualifying the path.
1151         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1152         $(top_srcdir).
1153
1154 2001-12-11  Marc Autret  <autret_m@epita.fr>
1155
1156         * src/output.c (output_parser): Remove useless muscle.
1157
1158 2001-12-11  Marc Autret  <autret_m@epita.fr>
1159
1160         * src/bison.simple: Remove #line just before %%epilogue. It
1161         is now handled in ...
1162         * src/reader.c (read_additionnal_code): Add the output of a
1163         #line for the epilogue.
1164
1165 2001-12-10  Marc Autret  <autret_m@epita.fr>
1166
1167         * src/reader.c (copy_definition): Re-use CPP-outed code which
1168         replace precedent remove.
1169         * src/bison.simple: Remove #line before %%prologue because
1170         %%input-line is wrong at this time.
1171
1172 2001-12-10  Marc Autret  <autret_m@epita.fr>
1173
1174         * src/reader.c (symbols_output): Clean up.
1175         * src/output.c (output_gram, output): Clean up.
1176
1177 2001-12-10  Akim Demaille  <akim@epita.fr>
1178
1179         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
1180         * src/LR0.c (set_state_table): here.
1181         * src/lalr.c (lalr): Call it.
1182
1183 2001-12-10  Akim Demaille  <akim@epita.fr>
1184
1185         * src/state.h (shifts): Remove the `number' member: shifts are
1186         attached to state, hence no longer need to be labelled with a
1187         state number.
1188
1189 2001-12-10  Akim Demaille  <akim@epita.fr>
1190
1191         Now that states have a complete set of members, the linked list of
1192         shifts is useless: just fill directly the state's shifts member.
1193
1194         * src/state.h (shifts): Remove the `next' member.
1195         * src/LR0.c (first_state, last_state): Remove.
1196         Adjust the callers.
1197         (augment_automaton): Don't look for the shifts that must be added
1198         a shift on EOF: it is those of the state we looked for!  But now,
1199         since shifts are attached, it is no longer needed to looking
1200         merely by its id: its number.
1201
1202 2001-12-10  Akim Demaille  <akim@epita.fr>
1203
1204         * src/LR0.c (augment_automaton): Better variable locality.
1205         Remove an impossible branch: if there is a state corresponding to
1206         the start symbol being shifted, then there is shift for the start
1207         symbol from the initial state.
1208
1209 2001-12-10  Akim Demaille  <akim@epita.fr>
1210
1211         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1212         only when appropriate: when insert_start_shifting_state' is not
1213         invoked.
1214         * tests/regression.at (Rule Line Numbers): Adjust.
1215
1216 2001-12-10  Akim Demaille  <akim@epita.fr>
1217
1218         * src/LR0.c (augment_automaton): Now that all states have shifts,
1219         merge the two cases addition shifts to the initial state.
1220
1221 2001-12-10  Akim Demaille  <akim@epita.fr>
1222
1223         * src/lalr.c (set_state_table): Move to...
1224         * src/LR0.c: here.
1225         * src/lalr.c (lalr): Don't call it...
1226         * src/LR0.c (generate_states): do it.
1227         * src/LR0.h (first_state): Remove, only the table is used.
1228
1229 2001-12-10  Akim Demaille  <akim@epita.fr>
1230
1231         * src/LR0.h (first_shift, first_reduction): Remove.
1232         * src/lalr.c: Don't use first_shift: find shifts through the
1233         states.
1234
1235 2001-12-10  Akim Demaille  <akim@epita.fr>
1236
1237         * src/LR0.c: Attach shifts to states as soon as they are
1238         computed.
1239         * src/lalr.c (set_state_table): Instead of assigning shifts to
1240         state, just assert that the mapping was properly done.
1241
1242 2001-12-10  Akim Demaille  <akim@epita.fr>
1243
1244         * src/LR0.c (insert_start_shift): Rename as...
1245         (insert_start_shifting_state): this.
1246         (insert_eof_shifting_state, insert_accepting_state): New.
1247         (augment_automaton): Adjust.
1248         Better locality of the variables.
1249         When looking if the start_symbol is shifted from the initial
1250         state, using `while (... symbol != start_symbol ...)' sounds
1251         better than `while (... symbol < start_symbol ...)': If fail
1252         to see how the order between symbols could be relevant!
1253
1254 2001-12-10  Akim Demaille  <akim@epita.fr>
1255
1256         * src/getargs.h: Don't declare `spec_name_prefix' and
1257         `spec_file_prefix', declared by src/files.h.
1258         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1259         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1260         * src/output.c (prepare): Adjust.
1261         * src/reader.c (symbols_output): Likewise.
1262         * src/vmsgetargs.c: Vaguely adjust, but who cares?
1263
1264 2001-12-10  Akim Demaille  <akim@epita.fr>
1265
1266         * src/muscle_tab.c (muscle_init): NULL is a better default than
1267         `"0"'.
1268
1269 2001-12-10  Akim Demaille  <akim@epita.fr>
1270
1271         * src/reader.c (reader): Calling symbols_output once is enough.
1272
1273 2001-12-10  Akim Demaille  <akim@epita.fr>
1274
1275         Now that states have a complete set of members, the linked list of
1276         reductions is useless: just fill directly the state's reductions
1277         member.
1278
1279         * src/state.h (struct reductions): Remove member `number' and
1280         `next'.
1281         * src/LR0.c (first_reduction, last_reduction): Remove.
1282         (save_reductions): Don't link the new reductions, store them in
1283         this_state.
1284         * src/lalr.c (set_state_table): No need to attach reductions to
1285         states, it's already done.
1286         * src/output.c (output_actions): No longer free the shifts, then
1287         the reductions, then the states: free all the states and their
1288         members.
1289
1290 2001-12-10  Akim Demaille  <akim@epita.fr>
1291
1292         * src/options.c (OPTN, DRTV, BOTH): New.
1293         (option_table): Use them.
1294
1295         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1296         the job of system.h.
1297         * src/options.c: Don't include stdio.h and xalloc.h for the same
1298         reasons.
1299
1300 2001-12-10  Akim Demaille  <akim@epita.fr>
1301
1302         * src/output.c (output, prepare): Make sure the values of the
1303         muscles `action' and `prologue' are 0-terminated.
1304
1305 2001-12-10  Akim Demaille  <akim@epita.fr>
1306
1307         Clean up GCC warnings.
1308
1309         * src/reader.c (copy_action): `buf' is not used.
1310         (parse_skel_decl): Be static.
1311         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1312         * src/options.h (create_long_option_table): Have a real prototype.
1313         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1314         (hash_delete_at): Return const void *.
1315         Adjust casts to preserve the const.
1316
1317 2001-12-10  Akim Demaille  <akim@epita.fr>
1318
1319         * configure.in: Require 2.52g.
1320         M4 is not needed, but AUTOM4TE is.
1321         * m4/m4.m4: Remove.
1322         * tests/Makefile.am: Adjust.
1323
1324 2001-12-10  Akim Demaille  <akim@epita.fr>
1325
1326         One structure for states is enough, even though theoretically
1327         there are LR(0) states and LALR(1) states.
1328
1329         * src/lalr.h (state_t): Remove.
1330         (state_table): Be state_t **, not state_t *.
1331         * src/state.h (core, CORE_ALLOC): Rename as...
1332         (state_t, STATE_ALLOC): this.
1333         Add the LALR(1) members: shifts, reductions, errs.
1334         * src/LR0.c (state_table): Rename as...
1335         (state_hash): this, to avoid name clashes with the global
1336         `state_table'.
1337         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1338         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
1339
1340 2001-12-10  Akim Demaille  <akim@epita.fr>
1341
1342         Bison dumps core on bash.y.
1343         Reported by Pascal Bart.
1344
1345         * src/warshall.c (bitmatrix_print): New.
1346         (TC): Use it.
1347         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1348         j must be the outer loop.
1349         * tests/regression.at (Broken Closure): New.
1350
1351 2001-12-05  Akim Demaille  <akim@epita.fr>
1352
1353         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1354         its argument.
1355         Reported by Peter Hámorský.
1356
1357 2001-12-05  Akim Demaille  <akim@epita.fr>
1358
1359         * src/conflicts.c (err_table): Remove.
1360         (resolve_sr_conflict): Adjust.
1361         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1362         Rename as...
1363         (state_t.reductions, state_t.shifts): this.
1364
1365 2001-12-05  Akim Demaille  <akim@epita.fr>
1366
1367         * src/reduce.c (reduce_grammar_tables): No longer disable the
1368         removal of useless rules via CPP but via `if (0)', so that the
1369         compiler still check the code is valid.
1370         For instance, it should have noticed `rline' no longer exists: use
1371         the `line' member of rule_t.
1372         * src/gram.c (dummy, rline): Remove, unused.
1373
1374 2001-12-05  Akim Demaille  <akim@epita.fr>
1375
1376         * src/output.c (pack_vector): Use assert, not berror.
1377         * src/main.c (berror): Remove, unused.
1378
1379 2001-12-05  Akim Demaille  <akim@epita.fr>
1380
1381         New experimental feature: if --verbose --trace output all the
1382         items of a state, not only its kernel.
1383
1384         * src/print.c (print_core): If `trace_flag', then invoke closure
1385         before outputting the items of the state (print_core is no longer
1386         a correct name them).
1387         (print_results): Invoke new_closure/free_closure if needed.
1388
1389 2001-12-05  Akim Demaille  <akim@epita.fr>
1390
1391         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1392         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1393         (nitemset): for consistency with the rest of the project.
1394
1395 2001-12-05  Akim Demaille  <akim@epita.fr>
1396
1397         * src/closure.c (print_closure): Improve.
1398         (closure): Use it for printing input and output.
1399
1400 2001-12-05  Akim Demaille  <akim@epita.fr>
1401
1402         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1403         indexed by nonterminals.
1404
1405 2001-12-05  Akim Demaille  <akim@epita.fr>
1406
1407         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1408         what it was!).
1409         * src/warshall.h: Remove accidental duplication of the content.
1410
1411 2001-12-05  Akim Demaille  <akim@epita.fr>
1412

1422
1423 2001-12-05  Akim Demaille  <akim@epita.fr>
1424
1425         * src/output.c (action_row): De-obfuscate
1426         using the good o' techniques: arrays not pointers, variable
1427         locality, BITISSET, RESETBIT etc.
1428
1429 2001-12-05  Akim Demaille  <akim@epita.fr>
1430
1431         Pessimize the code to simplify it: from now on, all the states
1432         have a valid SHIFTS, which NSHIFTS is possibly 0.
1433
1434         * src/LR0.c (shifts_new): Be global and move to..
1435         * src/state.c, src/state.h: here.
1436         * src/conflicts, src/lalr.c, src/output.c, src/print.c,

1440
1441         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1442         * src/conflicts.c: Use it.
1443         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1444         incorrectly ``simplified''.
1445
1446 2001-12-05  Akim Demaille  <akim@epita.fr>
1447
1448         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate

1454         * src/state.h (SHIFT_SYMBOL): New.
1455         * src/conflicts.c: Use it to deobfuscate.
1456
1457 2001-12-05  Akim Demaille  <akim@epita.fr>
1458
1459         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1460         (print_reductions): De-obfuscate using the good o' techniques:
1461         arrays not pointers, variable locality, BITISSET.
1462
1463 2001-12-05  Akim Demaille  <akim@epita.fr>
1464
1465         * src/conflicts.c (print_reductions): Arrays, not pointers.
1466         Use BITISSET.
1467
1468 2001-12-05  Akim Demaille  <akim@epita.fr>
1469
1470         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1471
1472 2001-12-05  Akim Demaille  <akim@epita.fr>
1473
1474         * src/conflicts.c (print_reductions): Improve variable locality.

1483
1484 2001-12-05  Akim Demaille  <akim@epita.fr>
1485
1486         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
1487         * src/lalr.c: Use them.
1488
1489 2001-12-05  Akim Demaille  <akim@epita.fr>
1490
1491         * src/LR0.c (augment_automaton): Formatting changes.
1492         Better variable locality.
1493
1494 2001-12-05  Akim Demaille  <akim@epita.fr>
1495
1496         * src/lalr.c (matrix_print): New.
1497         (transpose): Use it.
1498         Use arrays instead of pointers.
1499
1500 2001-12-05  Akim Demaille  <akim@epita.fr>
1501
1502         * src/lalr.c (maxrhs): Move to...
1503         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1504         * src/lalr.c (build_relations): Adjust.
1505
1506 2001-12-05  Akim Demaille  <akim@epita.fr>
1507
1508         * src/lalr.c (transpose): Free the memory allocated to the
1509         argument, as it is replaced by the results by the unique caller.
1510         (build_relations): Merely invoke transpose: it handles the memory
1511         deallocation.
1512         Improve variable locality.
1513         Avoid variables used as mere abbreviations.
1514         (compute_lookaheads): Use arrays instead of pointers.
1515
1516 2001-12-05  Akim Demaille  <akim@epita.fr>
1517
1518         * src/lalr.c (initialize_F): Improve variable locality.
1519         Avoid variables used as mere abbreviations.
1520
1521 2001-12-05  Akim Demaille  <akim@epita.fr>
1522
1523         * src/derives.c (print_derives): Display the ruleno.
1524         * src/lalr.c (initialize_F, transpose): Better variable locality
1525         to improve readability.
1526         Avoid variables used as mere abbreviations.
1527
1528 2001-12-05  Akim Demaille  <akim@epita.fr>
1529
1530         * src/lalr.c (traverse): Use arrays instead of pointers.
1531
1532 2001-12-05  Akim Demaille  <akim@epita.fr>
1533
1534         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1535         the handling of squeue.
1536         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1537
1538 2001-12-05  Akim Demaille  <akim@epita.fr>
1539
1540         Because useless nonterminals are now kept alive (instead of being
1541         `destroyed'), we now sometimes examine them, and store information
1542         related to them.  Hence we need to know their number, and adjust
1543         memory allocations.
1544
1545         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1546         static.
1547         * src/LR0.c (allocate_itemsets): The memory allocated to
1548         `symbol_count' was used for two different purpose: once to count
1549         the number of occurrences of each symbol, and later reassigned to
1550         `shift_symbol', containing the symbol that can be shifted from a
1551         given state.
1552         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1553         only, and...
1554         (new_itemsets): Allocate `shift_symbol' here.
1555         (allocate_itemsets): symbol_count includes useless nonterminals.
1556         Make room for them.
1557         (free_storage): Use `free', not `XFREE', for pointers that cannot
1558         be null.
1559
1560 2001-12-05  Akim Demaille  <akim@epita.fr>
1561
1562         * src/nullable.c (set_nullable): Deobfuscate the handling of
1563         ritem.
1564         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1565
1566 2001-12-05  Akim Demaille  <akim@epita.fr>
1567
1568         * src/gram.c, src/gram.h (ritem_print): New.
1569         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1570         (This useless function was defined only to work around VMS linkers
1571         that can't handle compilation units with variables only).
1572         * src/reduce.c (dump_grammar): Use it to trace the construction of
1573         ritem.
1574
1575 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1576
1577         * src/bison.simple (union yyalloc): Change member names
1578         to be the same as the stack names.
1579         (yyparse): yyptr is now union yyalloc *, not char *.
1580         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1581         and may generate better code on some machines.
1582         (yystpcpy): Use prototype if __STDC__ is defined, not just
1583         if __cplusplus is defined.
1584
1585 2001-11-30  Akim Demaille  <akim@epita.fr>
1586
1587         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1588         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1589         Gettext doesn't compile cleanly, and dies with -Werror.
1590         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1591         Include WARNING_CFLAGS here.
1592         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1593         before being defined.
1594
1595 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1596
1597         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1598         First arg is int, not unsigned.
1599         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1600         (SIZE_MAX, UINT_MAX): New macros.
1601         (quotearg_n_options): Abort if N is negative.
1602         Avoid overflow check on hosts where size_t is 64 bits and int
1603         is 32 bits, as overflow is impossible there.
1604         Fix off-by-one typo that caused unnecessary reallocation.
1605
1606 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1607
1608         Name space cleanup in generated parser.
1609
1610         * doc/bison.texinfo (Bison Parser): Discuss system headers
1611         and their effect on the user name space.
1612
1613         * src/bison.simple:
1614         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1615         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1616         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1617
1618         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1619         on user names when possible.
1620
1621         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1622         Simplify test for whather <alloca.h> exists.
1623
1624         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1625
1626         (<stdio.h>): Include if YYDEBUG.
1627
1628         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
1629         ! defined (yyoverflow) && ! defined (yymemcpy).
1630
1631         (yymemcpy, yyparse): Rename local variables as needed so that
1632         they all begin with 'yy'.
1633
1634         (yystrlen, yystpcpy): New functions.
1635
1636         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1637         All uses changed.
1638
1639         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1640         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1641         and YYSTACK_FREE instead of malloc and free.
1642
1643 2001-11-30  Akim Demaille  <akim@epita.fr>
1644
1645         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
1646         before their first uses.
1647         (YYBISON, YYPURE): Move to the top of the output.
1648

1650

1652
1653 2001-11-30  Akim Demaille  <akim@epita.fr>
1654
1655         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1656         if body instead of `;' to pacify GCC's warnings.
1657
1658 2001-11-30  Akim Demaille  <akim@epita.fr>
1659
1660         Instead of mapping the LHS of unused rules to -1, keep the LHS
1661         valid, but flag the rules as invalid.
1662
1663         * src/gram.h (rule_t): `useful' is a new member.
1664         * src/print.c (print_grammar): Adjust.
1665         * src/derives.c (set_derives): Likewise.
1666         * src/reader.c (packgram, reduce_output): Likewise.
1667         * src/reduce.c (reduce_grammar_tables): Likewise.
1668         * tests/reduce.at (Underivable Rules, Useless Rules): New.

1676
1677 2001-11-30  Akim Demaille  <akim@epita.fr>
1678
1679         * src/reduce.c (nonterminals_reduce): Instead of throwing away
1680         useless nonterminals, move them at the end of the symbol arrays.
1681         (reduce_output): Adjust.
1682         * tests/reduce.at (Useless Nonterminals): Adjust.
1683
1684 2001-11-30  Akim Demaille  <akim@epita.fr>
1685
1686         * src/reduce.c: Various comment/formatting changes.
1687         (nonterminals_reduce): New, extracted from...
1688         (reduce_grammar_tables): here.
1689         (reduce_grammar): Call nonterminals_reduce.
1690
1691 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1692
1693         * src/bison.simple (YYSTACK_REALLOC): Remove.
1694         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
1695         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
1696         New macros.
1697         (union yyalloc): New type.
1698         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1699         an arbitrary restriction on hosts where size_t is wider than int.
1700
1701         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1702         a parser stack overflow.  Allocate just one block of memory for all
1703         three stacks, instead of allocating three blocks; this typically is
1704         faster and reduces fragmentation.
1705
1706         Do not limit the number of items in the stack to a value that fits
1707         in 'int', as this is an arbitrary limit on hosts with 64-bit
1708         size_t and 32-bit int.
1709
1710 2001-11-29  Marc Autret  <autret_m@epita.fr>
1711
1712         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
1713         of defining YYERROR_VERBOSE.

1716 2001-11-28  Marc Autret  <autret_m@epita.fr>

1726         * src/output.c (error_verbose): Define here.
1727         (prepare): Echo name modification.
1728         * src/getargs.h: Clean its extern declaration.
1729         * src/getargs.c (error_verbose_flag): Remove.
1730         (getargs): Remove case 'e'.
1731         * src/options.c (option_table): 'error-verbose' is now seen as simple
1732         percent option.
1733         Include output.h.
1734
1735         * src/reader.c (read_declarations): Remove case tok_include.
1736         (parse_include_decl): Remove.

1738         * src/options.c (option_table): 'include' is now a simple command line
1739         option.
1740
1741 2001-11-28  Marc Autret  <autret_m@epita.fr>
1742
1743         * src/bison.simple: Adjust muscle names.
1744         * src/muscle_tab.c (muscle_init): Also rename the muscles.

1746         (output_parser): When scanning for a muscle, allow '-' instead of '_'.
1747
1748 2001-11-28  Marc Autret  <autret_m@epita.fr>

1757
1758 2001-11-28  Akim Demaille  <akim@epita.fr>
1759
1760         * src/closure.c (closure): `b' and `ruleno' denote the same value:
1761         keep ruleno only.
1762
1763 2001-11-28  Akim Demaille  <akim@epita.fr>
1764
1765         * src/closure.c (closure): Instead of looping over word in array
1766         then bits in words, loop over bits in array.
1767
1768 2001-11-28  Akim Demaille  <akim@epita.fr>
1769
1770         * src/closure.c (closure): No longer optimize the special case
1771         where all the bits of `ruleset[r]' are set to 0, to make the code
1772         clearer.
1773
1774 2001-11-28  Akim Demaille  <akim@epita.fr>
1775
1776         * src/closure.c (closure): `r' and `c' are new variables, used to
1777         de-obfuscate accesses to RULESET and CORE.

1790         * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
1791         * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
1792         as all tags are free'ed afterwards.
1793         From Enrico Scholz.
1794
1795 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1796
1797         * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
1798         use alloca when we didn't want to, and vice versa.
1799
1800 2001-11-27  Marc Autret  <autret_m@epita.fr>

3175         with something new. Skeletons are now processed character by character

3561         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3562         `%debug'.
3563         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3564         instead of returning a token.

3566         * src/reader.c (read_declarations): Adjust.

3590         * src/files.c (open_files): Fix the computation of short_base_name

3599 2000-12-20  Akim Demaille  <akim@epita.fr>
3600
3601         * src/files.c (open_files): Actually the `.output' file is based

3632         (base_names): Eve out from open_files.
3633         Try to simplify the rather hairy computation of base_name and
3634         short_base_name.
3635         (open_files): Use it.
3636         * tests/suite.at (Checking output file names): New test.

3675
3676         * src/files.c (open_files): Yipee!  We no longer need all the code
3677         looking for `/tmp' since we have no tmp file.

3708         * lib/obstack.h: Formatting changes.
3709         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3710         prevents type checking.
3711         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3712         cast the value to (void *): assigning a `foo *' to a `void *'
3713         variable is valid.
3714         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3715         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

3731
3732         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
3733         macros.

3750
3751 2000-11-07  Akim Demaille  <akim@epita.fr>
3752
3753         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

3778

3795         * src/main.c (main): Don't use `atexit' to register `done', since
3796         it no longer has to remove tmp files, just call `output_files'
3797         when there are no errors.
3798
3799 2000-11-02  Akim Demaille  <akim@epita.fr>

3900 2000-10-04  Akim Demaille  <akim@epita.fr>
3901
3902         When a literal string is used to define two different tokens,
3903         `bison -v' segfaults.
3904         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3905
3906         * tests/regression.m4: New file.
3907         Include the core of the sample provided by Piotr Gackiewicz.

3909         properly.

3912
3913         * src/reader.c (parse_expect_decl): Keep `count' within the size
3914         of `buffer'.
3915         From Neil Booth.
3916
3917 2000-10-02  Paul Eggert  <eggert@twinsun.com>
3918
3919         * bison.s1 (yyparse): Assign the default value
3920         unconditionally, to avoid a GCC warning and make the parser a
3921         tad smaller.
3922
3923 2000-10-02  Akim Demaille  <akim@epita.fr>
3924

3934
3935         The location tracking mechanism is precious for parse error
3936         messages.  Nevertheless, it is enabled only when `@n' is used in
3937         the grammar, which is a different issue (you can use it in error
3938         message, but not in the grammar per se).  Therefore, there should
3939         be another means to enable it.
3940
3941         * src/getargs.c (getargs): Support `--locations'.
3942         (usage): Report it.

3944         * src/lex.c (percent_table): Support `%locations'.

3946         with `locationsflag'.
3947         * doc/bison.texinfo: Document `--locations' and `%locations'.
3948         Sort the options.
3949         * tests/calc.m4: Test it.
3950
3951         For regularity of the names, replace each
3952         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3953         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3954         In addition replace each `flag' with `_flag'.
3955
3956 2000-10-02  Akim Demaille  <akim@epita.fr>
3957
3958         Also test parse error messages, including with YYERROR_VERBOSE.
3959
3960         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3961         associative).
3962         Use it to check the computations.
3963         Use it to check `nonassoc' is honored.
3964         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3965         `--yyerror-verbose'.
3966         (_AT_CHECK_CALC): Adjust to this option.
3967         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3968
3969 2000-10-02  Akim Demaille  <akim@epita.fr>
3970
3971         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
3972         the latter demonstrates a flaw in the handling of non debugging
3973         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3974         was used in order to simplify:
3975
3976         #if YYDEBUG
3977         if (yydebug)
3978         {
3979         ...
3980         }
3981         #endif
3982
3983         into
3984
3985         if (yydebug)
3986         {
3987         ...
3988         }
3989
3990         unfortunately this leads to a CPP conflict when
3991         `--name-prefix=foo' is used since it produces `#define yydebug
3992         foodebug'.
3993
3994         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3995         (YYDPRINTF): New macro.
3996         Spread its use.
3997         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3998         the bison options.
3999         Also test `--verbose', `--defines' and `--name-prefix'.

4003         Improve the readability of the produced parsers.
4004

4006         Improve the comment related to the `$' mark.
4007         (yydefault): Don't fall through to `yyresume': `goto' there.
4008         * src/output.c (output_parser): When the `$' is met, skip the end
4009         of its line.
4010         New variable, `number_of_dollar_signs', to check there's exactly
4011         one `$' in the parser skeleton.
4012
4013 2000-10-02  Akim Demaille  <akim@epita.fr>
4014
4015         * lib/xstrdup.c: New file, from the fileutils.
4016         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4017         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4018         instead of strlen + xmalloc + strcpy.
4019         * src/symtab.c (copys): Remove, use xstrdup instead.
4020
4021 2000-10-02  Akim Demaille  <akim@epita.fr>
4022
4023         * src/gram.h (associativity): New enum type which replaces the
4024         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4025         `right_assoc', `left_assoc' and `non_assoc'.
4026         Adjust all dependencies.
4027         * src/reader.c: Formatting changes.
4028         (LTYPESTR): Don't define it, use it as a literal in
4029         `reader_output_yylsp'.
4030         * src/symtab.h (symbol_class): New enum type which replaces the
4031         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4032         `sunknown', `stoken and `snterm'.
4033
4034 2000-10-02  Akim Demaille  <akim@epita.fr>
4035
4036         * src/getargs.c (fixed_outfiles): Rename as...

4038         Adjust dependencies.
4039
4040 2000-10-02  Akim Demaille  <akim@epita.fr>
4041
4042         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4043         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4044         difficult and introduced a lot of core dump.  It turns out that
4045         Bison used an implementation of `xmalloc' based on `calloc', and
4046         at various places it does depend upon the initialization to 0.  I
4047         have not tried to isolate the pertinent places, and all the former
4048         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4049         someone should address this issue.
4050
4051         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4052         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
4053         files.
4054         Adjust dependencies.

4056         Propagate.

4063
4064 2000-10-02  Akim Demaille  <akim@epita.fr>
4065
4066         * src/state.h (nstates, final_state, first_state, first_shift)
4067         (first_reduction): Move their exportation from here...
4068         * src/LR0.h: to here.

4145
4146         * src/output.c (token_actions): Introduce a temporary array,

4149
4150 2000-10-02  Akim Demaille  <akim@epita.fr>
4151
4152         `user_toknums' is output as a `short[]' in `output.c', while it is
4153         defined as a `int[]' in `reader.c'.  For consistency with the
4154         other output tables, `user_toknums' is now defined as a table of
4155         shorts.
4156
4157         * src/reader.c (user_toknums): Be a short table instead of an int
4158         table.

4170         order to get rid of the `static' prototypes.
4171         No longer use `register'.
4172         * src/output.h: New file.
4173         Propagate its inclusion in files explicitly prototyping functions
4174         from output.c.

4196         inclusion.
4197         Don't define PARAMS.
4198         * src/system.h: Define PARAMS.
4199         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
4200         purpose of config.h.  system.h must not try to fix wrong
4201         definitions in config.h.

4361
4362         * src/Makefile.am (bison.simple): Fix the awk program: quote only
4363         the file name, not the whole `#line LINE FILE'.
4364
4365 2000-03-17  Akim Demaille  <akim@epita.fr>
4366
4367         On syntax errors, report the token on which we choked.
4368
4369         * src/bison.s1 (yyparse): In the label yyerrlab, when

4387

4389         copy_comment.  Removed now unused `match', `ended',
4390         `cplus_comment'.
4391         (copy_comment, copy_string): Moved, to be visible from
4392         copy_definition.
4393

4395
4396         * src/reader.c (copy_string): Declare `static inline'.  No

4417 2000-03-17  Akim Demaille  <akim@epita.fr>
4418
4419         Change the handling of @s so that they behave exactly like $s.
4420         There is now a pseudo variable @$ (readble and writable), location
4421         of the lhs of the rule (by default ranging from the location of
4422         the first symbol of the rhs, to the location of the last symbol,
4423         or, if the rhs is empty, YYLLOC).
4424
4425         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4426         yyval.
4427         (yyparse): When providing a default semantic action, provide a
4428         default location action.
4429         (after the $): No longer change `*YYLSP', just stack YYLOC the
4430         same way you stack YYVAL.
4431         * src/reader.c (read_declarations): Use warns.
4432         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4433         (copy_action, case '@'): Likewise.
4434         Use a standard error message, to save useless work from
4435         translators.
4436
4437 2000-03-17  Akim Demaille  <akim@epita.fr>
4438
4439         * src/bison.s1: Formatting and cosmetics changes.

4441         Update the Copyright notice.
4442
4443 2000-03-17  Akim Demaille  <akim@epita.fr>
4444
4445         * src/bison.s1 (#line): All set to `#line' only, since the
4446         Makefile now handles them.
4447
4448 2000-03-16  Akim Demaille  <akim@epita.fr>

4456
4457         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4458         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4459         One `#if YYDEBUG' remains, since it uses variables which are
4460         defined only if `YYDEBUG != 0'.
4461
4462 2000-03-16  Akim Demaille  <akim@epita.fr>
4463
4464         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

4474
4475 2000-03-16  Akim Demaille  <akim@epita.fr>
4476

4485         * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
4486         handled via src/Makefile.am.
4487         (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
4488         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
4489         autoheader.

4494         the proper line number and file name.
4495         (DEFS): Propagate the location of bison library files and of the
4496         locale files.
4497         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4498         builddir.
4499         * acinclude.m4: Remove, replaced by the directory m4.
4500         * m4/Makefile.am (EXTRA_DIST): New variable.
4501         * m4/gettext.m4: New file, from the fileutils.

5147         (get_type, packsymbols):  Revised most error messages.
5148         Changed `fatal' to `warnxxx' to avoid aborting for error.
5149         Revised and use multiple warnxxx functions to avoid using VARARGS1.

5167         (fatals): Updated to not use VARARGS1.
5168         (printable_version, int_to_string, warn, warni, warns, warnss)

5187         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
5188         major changes to files.c.
5189         (lex) Retain in the incoming stream a character following
5190         an incorrect '/'.
5191         (skip_white_space, lex):  Revised most error messages
5192         and changed fatal to warn to avoid aborting.
