  20
  21         * data/bison.c++: Copy the prologue of bison.simple to fetch
  22         useful M4 definitions, such as b4_header_guard.
  23
  24 2002-02-25  Akim Demaille  <akim@epita.fr>
  25
  26         * src/getargs.c (version): Give the name of the authors, and use a
  27         translator friendly scheme for the bgr

  40         hard coded name.
  41
  42 2002-02-25  Akim Demaille  <akim@epita.fr>
  43
  44         * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from

  54
  55 2002-02-14  Paul Eggert  <eggert@twinsun.com>
  56
  57         Remove the support for C++ namespace cleanliness; it was
  58         causing more problems than it was curing, since it didn't work
  59         properly on some nonstandard C++ compilers.  This can wait
  60         for a proper C++ parser.
  61
  62         * NEWS: Document this.
  63         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
  64         of C++, as it's treated like C now.
  65         * src/bison.simple (YYSTD): Remove.
  66         (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
  67         Treat C++ just like Standard C instead of trying to support
  68         namespace cleanliness.
  69
  70 2002-02-14  Akim Demaille  <akim@epita.fr>
  71
  72         * tests/regression.at (else): Adjust to Andreas' change.
  73
  74 2002-02-14  Akim Demaille  <akim@epita.fr>
  75
  76         * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
  77
  78 2002-02-13  Andreas Schwab  <schwab@suse.de>
  79
  80         * src/output.c (output_rule_data): Don't output NULL, it might
  81         not be defined yet.
  82
  83 2002-02-11  Robert Anisko  <robert@lrde.epita.fr>
  84
  85         * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.

  89
  90         * tests/regression.at (%nonassoc and eof): Don't include
  91         nonportable headers.
  92
  93 2002-02-08  Robert Anisko  <robert@lrde.epita.fr>
  94
  95         * data/bison.c++: Correct error recovery.  Make the user able to
  96         initialize the starting location.
  97
  98 2002-02-07  Akim Demaille  <akim@epita.fr>
  99
 100         * tests/input.at: New.
 101
 102 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 103
 104         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
 105         more consistent when naming methods and variables.  Put preprocessor
 106         directives around tables only needed for debugging.
 107
 108 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 109
 110         * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
 111         C++ parsers.
 112         (yy::b4_name::parse): Use print_.
 113
 114 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 115
 116         * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
 117
 118 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 119
 120         * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
 121         C++ parsers.
 122         (yy::b4_name::parse): Build verbose error messages, and use error_.
 123
 124 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
 125
 126         * data/bison.c++: Fix m4 quoting in comments.
 127
 128 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
 129
 130         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
 131         not expanded by m4.
 132
 133 2002-02-05  Akim Demaille  <akim@epita.fr>
 134
 135         * data/bison.c++: Adjust to the M4 back end.
 136         More is certainly needed.
 137
 138 2002-02-05  Akim Demaille  <akim@epita.fr>
 139
 140         Give a try to M4 as a back end.
 141
 142         * lib/readpipe.c: New, from wdiff.
 143         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
 144         BISON_HAIRY.
 145         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
 146         specific values.  Now it is m4 that performs the lookup.
 147         * src/parse-skel.y: Remove.
 148         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
 149         * src/output.c (actions_output, guards_output)
 150         (token_definitions_output): No longer keeps track of the output
 151         line number, hence remove the second argument.
 152         (guards_output): Check against the guard member of a rule, not the
 153         action member.
 154         Adjust callers.
 155         (output_skeleton): Don't look for the skeleton location, let m4 do
 156         that.
 157         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
 158         file will be used.
 159         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
 160         (prepare): Given that for the time being changesyntax is not
 161         usable in M4, rename the muscles using `-' to `_'.
 162         Define `defines_flag', `output_parser_name' and `output_header_name'.
 163         * src/output.h (actions_output, guards_output)
 164         (token_definitions_output): Adjust prototypes.
 165         * src/scan-skel.l: Instead of scanning the skeletons, it now
 166         processes the output of m4: `__oline__' and `#output'.
 167         * data/bison.simple: Adjust to be used by M4(sugar).
 168         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
 169         to date.
 170         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
 171         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
 172         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
 173         shamelessly stolen from CVS Autoconf.
 174
 175 2002-02-05  Akim Demaille  <akim@epita.fr>
 176
 177         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
 178         * configure.in: Check for the declarations of free and malloc.
 179         * src/muscle_tab.c: Adjust.
 180
 181 2002-02-05  Akim Demaille  <akim@epita.fr>
 182
 183         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
 184         which have no values.
 185
 186 2002-02-05  Akim Demaille  <akim@epita.fr>
 187
 188         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
 189         * data/: here.
 190
 191 2002-01-29  Paul Eggert  <eggert@twinsun.com>
 192
 193         * src/bison.simple (YYSIZE_T): Do not define merely because
 194         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 195         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 196
 197 2002-01-27  Akim Demaille  <akim@epita.fr>
 198
 199         Fix `%nonassoc and eof'.
 200
 201         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
 202         which were not properly copied!  Replace
 203         memcpy (res->errs, src->errs, src->nerrs);
 204         with
 205         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
 206         !!!
 207         * tests/regression.at (%nonassoc and eof): Adjust to newest
 208         Autotest: `.' is not in the PATH.
 209
 210 2002-01-27  Akim Demaille  <akim@epita.fr>
 211
 212         * tests/sets.at (AT_EXTRACT_SETS): New.
 213         (Nullable): Use it.
 214         (Firsts): New.
 215
 216 2002-01-26  Akim Demaille  <akim@epita.fr>
 217
 218         * tests/actions.at, tests/calc.at, tests/headers.at,
 219         * tests/torture.at: Adjust to the newest Autotest which no longer
 220         forces `.' in the PATH.
 221
 222 2002-01-25  Akim Demaille  <akim@epita.fr>
 223
 224         * tests/regression.at (%nonassoc and eof): New.
 225         Suggested by Robert Anisko.
 226
 227 2002-01-24  Akim Demaille  <akim@epita.fr>
 228
 229         Bison dumps core when trying to complain about broken input files.
 230         Reported by Cris van Pelt.
 231
 232         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
 233         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
 234         into...
 235         (Invalid inputs): Strengthen: exercise parse_percent_token.
 236
 237 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
 238
 239         * src/Makefile.am: Add bison.c++.
 240         * src/bison.c++: New skeleton.
 241
 242 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
 243
 244         * po/it.po: New.
 245
 246 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
 247
 248         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
 249
 250 2002-01-20  Marc Autret  <marc@gnu.org>
 251
 252         * src/files.c (compute_output_file_names): Fix
 253
 254 2002-01-20  Marc Autret  <marc@gnu.org>
 255
 256         * tests/output.at: New test.
 257         * src/files.c (compute_base_names): Don't map extensions when
 258         the YACC flag is set, use defaults.
 259         Reported by Evgeny Stambulchik.
 260
 261 2002-01-20  Marc Autret  <marc@gnu.org>
 262
 263         * src/system.h: Need to define __attribute__ away for non-GCC
 264         compilers as well (i.e. the vendor C compiler).
 265         Suggested by Albert Chin-A-Young.
 266
 267 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
 268
 269         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
 270         canonical definition.
 271         * src/system.h: Use the canonical definition for PARAMS (avoids
 272         a conflict with the macro from lib/hash.h).
 273
 274 2002-01-11  Akim Demaille  <akim@epita.fr>
 275
 276         * configure.in: Use AC_FUNC_STRNLEN.
 277         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
 278
 279 2002-01-09  Akim Demaille  <akim@epita.fr>
 280
 281         * src/files.c, src/files.h (output_infix): New.
 282         (tab_extension): Remove.
 283         (compute_base_names): Compute the former, drop the latter.
 284         * src/output.c (prepare): Insert the muscles `output-infix', and
 285         `output-suffix'.
 286         * src/parse-skel.y (string, string.1): New.
 287         (section.header): Use it.
 288         (section.yacc): Remove.
 289         (prefix): Remove too.
 290         * src/scan-skel.l: Adjust.
 291         * src/bison.simple, src/bison.hairy: Adjust.
 292
 293 2002-01-09  Akim Demaille  <akim@epita.fr>
 294
 295         * configure.in (WERROR_CFLAGS): Compute it.
 296         * src/Makefile.am (CFLAGS): Pass it.
 297         * tests/atlocal.in (CFLAGS): Idem.

 300
 301 2002-01-08  Akim Demaille  <akim@epita.fr>
 302
 303         * src/getargs.c (AS_FILE_NAME): New.
 304         (getargs): Use it to convert DOSish file names.
 305         * src/files.c (base_name): Rename as full_base_name to avoid
 306         clashes with `base_name ()'.
 307         (filename_split): New.
 308         (compute_base_names): N-th rewrite, using filename_split.
 309
 310 2002-01-08  Akim Demaille  <akim@epita.fr>
 311
 312         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
 313         New, stolen from the Fileutils 4.1.
 314         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
 315         * configure.in: Check for the presence of memrchr, and of its
 316         prototype.
 317
 318 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
 319
 320         * lib/hash.h (__P): Added definition for this macro.
 321         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
 322         BUILT_SOURCES, to ensure they are generated first.
 323         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
 324         %error-verbose to allow bootstrapping with bison 1.30x.
 325
 326 2002-01-06  Akim Demaille  <akim@epita.fr>
 327
 328         * src/reader.c (parse_braces): Don't fetch the next char, the
 329         convention is to fetch on entry.
 330         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
 331         'switch' without a following semicolon.
 332         * tests/regression.at (braces parsing): New.
 333
 334 2002-01-06  Akim Demaille  <akim@epita.fr>
 335
 336         Bison is dead wrong in its RR conflict reports.
 337
 338         * tests/torture.at (GNU Cim Grammar): New.
 339         * src/conflicts.c (count_rr_conflicts): Fix.
 340
 341 2002-01-06  Akim Demaille  <akim@epita.fr>
 342
 343         Creating package.m4 from configure.ac causes too many problems.
 344
 345         * tests/Makefile.am (package.m4): Create it by hand,
 346         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
 347
 348 2002-01-06  Akim Demaille  <akim@epita.fr>
 349
 350         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
 351         skeleton.h.
 352
 353 2002-01-04  Paul Eggert  <eggert@twinsun.com>
 354
 355         * doc/bison.texinfo (Debugging):
 356         Remove YYSTDERR; it's no longer defined or used.
 357         Also, s/cstdio.h/cstdio/.
 358
 359 2002-01-03  Akim Demaille  <akim@epita.fr>
 360
 361         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
 362
 363 2002-01-03  Akim Demaille  <akim@epita.fr>
 364
 365         * src/parse-skel.y (process_skeleton): Don't bind the parser's
 366         tracing code to --trace, wait for a better --trace option, with
 367         args.
 368
 369 2002-01-03  Akim Demaille  <akim@epita.fr>
 370
 371         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
 372         The ISO C++ standard is extremely clear about it: stderr is
 373         considered a macro, not a regular symbol (see table 94 `Header
 374         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
 375         Therefore std:: does not apply to it.  It still does with fprintf.
 376         Also, s/cstdio.h/cstdio/.

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

 820         * src/LR0.c (set_state_table): Let all the states have an errs,
 821         even if reduced to 0.
 822         * src/print.c (print_errs, print_reductions): Adjust.
 823         * src/output.c (output_actions, action_row): Adjust.

 827
 828         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 829
 830 2001-12-27  Akim Demaille  <akim@epita.fr>
 831
 832         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 833         * src/print.c: here.
 834         (lookaheadset, shiftset): New, used as additional storage by
 835         print_reductions.
 836         (print_results): Adjust.
 837         (print_shifts, print_gotos, print_errs): New, extracted from...
 838         (print_actions): here.
 839         * src/print_graph.c (print_actions): Remove dead code.
 840
 841 2001-12-27  Akim Demaille  <akim@epita.fr>
 842
 843         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 844         `$n' and `@n'.
 845
 846 2001-12-27  Akim Demaille  <akim@epita.fr>
 847
 848         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 849         (build_relations): Adjust.
 850
 851 2001-12-27  Akim Demaille  <akim@epita.fr>
 852
 853         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 854         duplication.
 855
 856 2001-12-27  Akim Demaille  <akim@epita.fr>
 857
 858         * src/reader.c (packgram): Catch nitems overflows.
 859
 860 2001-12-27  Akim Demaille  <akim@epita.fr>
 861
 862         * src/files.c, src/files.h (guard_obstack): Remove.
 863         * src/output.c (output): Adjust.
 864         * src/reader.c (parse_braces): New, factoring...
 865         (copy_action, copy_guard): these two which are renamed as...
 866         (parse_action, parse_guard): these.
 867         As a voluntary consequence, using braces around guards is now
 868         mandatory.
 869
 870 2001-12-27  Akim Demaille  <akim@epita.fr>
 871
 872         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 873         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 874         members.
 875         (symbol_list_new): Adjust.
 876         (copy_action): action_line is the first line, not the last.
 877         (copy_guard): Just as for actions, store the `action' only, not
 878         the switch/case/break flesh.
 879         Don't parse the user action that might follow the guard, let...
 880         (readgram): do it, i.e., now, there can be an action after a
 881         guard.
 882         In other words the guard is just explicitly optional.
 883         (packgram): Adjust.
 884         * src/output.c (guards_output): New.
 885         (output_parser): Call it when needed.
 886         (output): Also free the guard and attrs obstacks.
 887         * src/files.c, src/files.h (obstack_save): Remove.
 888         (output_files): Remove.
 889         As a result, if one needs the former `.act' file, using an
 890         appropriate skeleton which requires actions and guards is now
 891         required.
 892         * src/main.c (main): Adjust.
 893         * tests/semantic.at: New.
 894         * tests/regression.at: Use `input.y' as input file name.
 895         Avoid 8+3 problems by requiring input.c when the test needs the
 896         parser.
 897
 898 2001-12-27  Akim Demaille  <akim@epita.fr>
 899
 900         * src/reader.c (symbol_list_new): Be sure to initialize all the
 901         fields.
 902
 903 2001-12-27  Akim Demaille  <akim@epita.fr>
 904
 905         All the hacks using a final pseudo state are now useless.
 906
 907         * src/LR0.c (set_state_table): state_table holds exactly nstates.
 908         * src/lalr.c (nLA): New.
 909         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
 910         instead of lookaheadsp from the pseudo state (nstate + 1).
 911
 912 2001-12-27  Akim Demaille  <akim@epita.fr>
 913
 914         * src/output.c (action_row, token_actions): Use a state_t instead
 915         of a integer, and nlookaheads instead of the following state's
 916         lookaheadsp.
 917
 918 2001-12-27  Akim Demaille  <akim@epita.fr>

 922         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
 923         (conflicts_print, print_reductions): Use a state_t instead of an
 924         integer when referring to a state.
 925         As much as possible, depend upon nlookaheads, instead of the
 926         `lookaheadsp' member of the following state (since lookaheads of
 927         successive states are successive, the difference between state n + 1
 928         and n served as the number of lookaheads for state n).
 929         * src/lalr.c (add_lookback_edge): Likewise.
 930         * src/print.c (print_core, print_actions, print_state)
 931         (print_results): Likewise.
 932         * src/print_graph.c (print_core, print_actions, print_state)
 933         (print_graph): Likewise.

 939         ANSIfy.
 940         Remove `register' indications.
 941         Add plenty of `static'.

 943 2001-12-27  Akim Demaille  <akim@epita.fr>
 944
 945         * src/output.c (prepare): Drop the muscle `ntbase' which
 946         duplicates ntokens.
 947         * src/bison.simple: Formatting/comment changes.
 948         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
 949         is an undocumented synonym.
 950
 951 2001-12-22  Akim Demaille  <akim@epita.fr>
 952
 953         * src/output.c (output_table_data): Change the prototype to use
 954         `int' for array ranges: some invocations do pass an int, not a
 955         short.
 956         Reported by Wayne Green.

 970         Reductions in web2c.y are improperly reported.
 971         Reported by Mike Castle.

 974         * tests/regression.at (Web2c): New.
 975
 976 2001-12-18  Akim Demaille  <akim@epita.fr>
 977
 978         Some host fail on `assert (!"foo")', which expands to
 979         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
 980         Reported by Nelson Beebee.
 981
 982         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
 983         `#define it_succeeded 0' and `assert (it_succeeded)'.
 984
 985 2001-12-17  Marc Autret  <autret_m@epita.fr>
 986
 987         * src/bison.simple: Don't hard code the skeleton line and filename.
 988         * src/output.c (output_parser): Rename 'line' as 'output_line'.
 989         New line counter 'skeleton_line' (skeleton-line muscle).
 990
 991 2001-12-17  Paul Eggert  <eggert@twinsun.com>
 992
 993         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
 994         YYDEBUG must be defined to a nonzero value.
 995
 996         * src/bison.simple (yytname): Do not assume that the user defines
 997         YYDEBUG to a properly parenthesized expression.
 998
 999 2001-12-17  Akim Demaille  <akim@epita.fr>
1000
1001         * src/state.h (state_t): Rename lookaheads as lookaheadsp.

1020
1021         * src/conflicts.c (flush_shift): Also adjust lookaheadset.

1025 2001-12-17  Akim Demaille  <akim@epita.fr>
1026
1027         * src/output.c (output_obstack): Be static and rename as...

1052
1053         * src/output.c (actions_output): Fix. When we use %no-lines,
1054         there is one less line per action.
1055
1056 2001-12-16  Marc Autret  <autret_m@epita.fr>
1057
1058         * src/bison.simple: Remove a useless #line directive.
1059         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1060         * src/output.c (get_lines_number): New.
1061         (output_parser): Adjust, now takes care about the lines of a
1062         output muscles.
1063         Fix line numbering.
1064         (actions_output): Computes the number of lines taken by actions.
1065         (output_master_parser): Insert new skeleton which is the name of

1076 2001-12-15  Akim Demaille  <akim@epita.fr>
1077
1078         Make `make distcheck' work.
1079
1080         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1081         system.h which uses libgettext.h.
1082
1083 2001-12-15  Akim Demaille  <akim@epita.fr>
1084
1085         * src/nullable.c (set_nullable): Useless rules must be skipped,
1086         otherwise, since we range over their symbols, we might look at a
1087         nonterminal which no longer ``exists'', i.e., it is not counted in
1088         `nvars', hence we overflow our arrays.
1089

1091
1092         The header can also be produced directly, without any obstack!

1098         * src/reader.c (parse_union_decl): No longer output to

1100         anyway.
1101         (output_token_translations): Merge into...

1103         Rename as...
1104         (symbols_save): this.
1105         (reader): Adjust.
1106         * src/output.c (header_output): New.
1107         (output): Call it.
1108
1109 2001-12-15  Akim Demaille  <akim@epita.fr>
1110
1111         * src/reader.c (parse_union_decl): Instead of handling two obstack
1112         simultaneously, use one to define the `stype' muscle, and use the
1113         value of the latter to fill defines_obstack.
1114         (copy_comment): Remove.
1115         (copy_comment2): Work for a single obstack.
1116         Rename as...
1117         (copy_comment): this.
1118
1119 2001-12-15  Akim Demaille  <akim@epita.fr>
1120
1121         * src/lex.c, src/lex.h (xgetc): No longer static.
1122         * src/reader.c (parse_union_decl): Revamp.
1123
1124 2001-12-15  Akim Demaille  <akim@epita.fr>
1125
1126         Still making progress in separating Bison into (i) input, (ii)
1127         process, (iii) output: now we can directly output the parser file
1128         without using table_obstack at all.
1129
1130         * src/files.c, src/files.h (table_obstack): Bye bye.
1131         (parser_file_name): New.
1132         * src/files.c (compute_output_file_names): Compute it.
1133         * src/output.c (actions_output, output_parser)
1134         (output_master_parser): To a file instead of an obstack.
1135
1136 2001-12-15  Akim Demaille  <akim@epita.fr>
1137
1138         Attach actions to rules, instead of pre-outputting them to
1139         actions_obstack.
1140
1141         * src/gram.h (rule_t): action and action_line are new members.
1142         * src/reader.c (symbol_list): Likewise.
1143         (copy_action): Save the actions within the rule.
1144         (packgram): Save them in rule_table.
1145         * src/output.c (actions_output): New.
1146         (output_parser): Use it on `%%actions'.
1147         (output_rule_data): Don't free rule_table.
1148         (output): Do it.
1149         (prepare): Don't save the `action' muscle.
1150         * src/bison.simple: s/%%action/%%actions/.
1151
1152 2001-12-15  Akim Demaille  <akim@epita.fr>
1153
1154         * src/reader.c (copy_action): When --yacc, don't append a `;'
1155         to the user action: let it fail if lacking.
1156         Suggested by Arnold Robbins and Tom Tromey.
1157
1158 2001-12-14  Akim Demaille  <akim@epita.fr>
1159
1160         * src/lex.c (literalchar): Simply return the char you decoded, non
1161         longer mess around with obstacks and int pointers.
1162         Adjust all callers.
1163
1164 2001-12-14  Akim Demaille  <akim@epita.fr>
1165
1166         * src/lex.c (literalchar): Don't escape the special characters,
1167         just decode them, and keep them as char (before, eol was output as
1168         the 2 char string `\n' etc.).
1169         * src/output.c (output_rule_data): Use quotearg to output the
1170         token strings.
1171
1172 2001-12-13  Paul Eggert  <eggert@twinsun.com>
1173
1174         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1175         Do not infringe on the global user namespace when using C++.
1176         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1177         All uses of `fprintf' and `stderr' changed.
1178
1179         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1180
1181 2001-12-13  Akim Demaille  <akim@epita.fr>
1182
1183         The computation of nullable is broken: it doesn't handle empty
1184         RHS's properly.
1185
1186         * tests/torture.at (GNU AWK Grammar): New.
1187         * tests/sets.at (Nullable): New.
1188         * src/nullable.c (set_nullable): Instead of blindly looping over
1189         `ritems', loop over the rules, and then over their rhs's.
1190
1191         Work around Autotest bugs.
1192
1193         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1194         frame, because Autotest understand lines starting with a `+' as
1195         traces from the shell.  Then, they are not processed properly.
1196         Admittedly an Autotest bug, but we don't have time to wait for
1197         Autotest to catch up.
1198         * tests/regression.at (Broken Closure): Adjust to the new table
1199         frames.
1200         Move to...
1201         * tests/sets.at: here.
1202
1203 2001-12-13  Akim Demaille  <akim@epita.fr>
1204
1205         * src/closure.c (closure): Use nrules instead of playing tricks
1206         with BITS_PER_WORD.
1207
1208 2001-12-13  Akim Demaille  <akim@epita.fr>
1209
1210         * src/print.c (print_actions): Output the handling of `$' as the
1211         traces do: shifting the token EOF.  Before EOF was treated as a
1212         nonterminal.
1213         * tests/regression.at: Adjust some tests.
1214         * src/print_graph.c (print_core): Complete the set of items via
1215         closure.  The next-to-final and final states are still unsatisfying,
1216         but that's to be addressed elsewhere.
1217         No longer output the rule numbers, but do output the state number.
1218         A single loop for the shifts + gotos is enough, but picked a
1219         distinct color for each.
1220         (print_graph): Initialize and finalize closure.
1221
1222 2001-12-13  Akim Demaille  <akim@epita.fr>
1223
1224         * src/reader.c (readgram): Remove dead code, an strip useless
1225         braces.
1226         (get_type): Remove, unused.
1227
1228 2001-12-12  Akim Demaille  <akim@epita.fr>
1229
1230         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1231         on that of lib/error.c.
1232
1233 2001-12-12  Akim Demaille  <akim@epita.fr>
1234
1235         Some hosts don't like `/' in includes.
1236
1237         * src/system.h: Include libgettext.h without qualifying the path.
1238         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1239         $(top_srcdir).
1240
1241 2001-12-11  Marc Autret  <autret_m@epita.fr>
1242
1243         * src/output.c (output_parser): Remove useless muscle.
1244
1245 2001-12-11  Marc Autret  <autret_m@epita.fr>
1246
1247         * src/bison.simple: Remove #line just before %%epilogue. It
1248         is now handled in ...
1249         * src/reader.c (read_additionnal_code): Add the output of a
1250         #line for the epilogue.
1251
1252 2001-12-10  Marc Autret  <autret_m@epita.fr>
1253
1254         * src/reader.c (copy_definition): Re-use CPP-outed code which
1255         replace precedent remove.
1256         * src/bison.simple: Remove #line before %%prologue because
1257         %%input-line is wrong at this time.
1258
1259 2001-12-10  Marc Autret  <autret_m@epita.fr>
1260
1261         * src/reader.c (symbols_output): Clean up.
1262         * src/output.c (output_gram, output): Clean up.
1263
1264 2001-12-10  Akim Demaille  <akim@epita.fr>
1265
1266         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
1267         * src/LR0.c (set_state_table): here.
1268         * src/lalr.c (lalr): Call it.
1269
1270 2001-12-10  Akim Demaille  <akim@epita.fr>
1271
1272         * src/state.h (shifts): Remove the `number' member: shifts are
1273         attached to state, hence no longer need to be labelled with a
1274         state number.
1275
1276 2001-12-10  Akim Demaille  <akim@epita.fr>
1277
1278         Now that states have a complete set of members, the linked list of
1279         shifts is useless: just fill directly the state's shifts member.
1280
1281         * src/state.h (shifts): Remove the `next' member.
1282         * src/LR0.c (first_state, last_state): Remove.
1283         Adjust the callers.
1284         (augment_automaton): Don't look for the shifts that must be added
1285         a shift on EOF: it is those of the state we looked for!  But now,
1286         since shifts are attached, it is no longer needed to looking
1287         merely by its id: its number.
1288
1289 2001-12-10  Akim Demaille  <akim@epita.fr>
1290
1291         * src/LR0.c (augment_automaton): Better variable locality.
1292         Remove an impossible branch: if there is a state corresponding to
1293         the start symbol being shifted, then there is shift for the start
1294         symbol from the initial state.
1295
1296 2001-12-10  Akim Demaille  <akim@epita.fr>
1297
1298         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1299         only when appropriate: when insert_start_shifting_state' is not
1300         invoked.
1301         * tests/regression.at (Rule Line Numbers): Adjust.
1302
1303 2001-12-10  Akim Demaille  <akim@epita.fr>
1304
1305         * src/LR0.c (augment_automaton): Now that all states have shifts,
1306         merge the two cases addition shifts to the initial state.
1307
1308 2001-12-10  Akim Demaille  <akim@epita.fr>
1309
1310         * src/lalr.c (set_state_table): Move to...
1311         * src/LR0.c: here.
1312         * src/lalr.c (lalr): Don't call it...
1313         * src/LR0.c (generate_states): do it.
1314         * src/LR0.h (first_state): Remove, only the table is used.
1315
1316 2001-12-10  Akim Demaille  <akim@epita.fr>
1317
1318         * src/LR0.h (first_shift, first_reduction): Remove.
1319         * src/lalr.c: Don't use first_shift: find shifts through the
1320         states.
1321
1322 2001-12-10  Akim Demaille  <akim@epita.fr>
1323
1324         * src/LR0.c: Attach shifts to states as soon as they are
1325         computed.
1326         * src/lalr.c (set_state_table): Instead of assigning shifts to
1327         state, just assert that the mapping was properly done.
1328
1329 2001-12-10  Akim Demaille  <akim@epita.fr>
1330
1331         * src/LR0.c (insert_start_shift): Rename as...
1332         (insert_start_shifting_state): this.
1333         (insert_eof_shifting_state, insert_accepting_state): New.
1334         (augment_automaton): Adjust.
1335         Better locality of the variables.
1336         When looking if the start_symbol is shifted from the initial
1337         state, using `while (... symbol != start_symbol ...)' sounds
1338         better than `while (... symbol < start_symbol ...)': If fail
1339         to see how the order between symbols could be relevant!
1340
1341 2001-12-10  Akim Demaille  <akim@epita.fr>
1342
1343         * src/getargs.h: Don't declare `spec_name_prefix' and
1344         `spec_file_prefix', declared by src/files.h.
1345         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1346         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1347         * src/output.c (prepare): Adjust.
1348         * src/reader.c (symbols_output): Likewise.
1349         * src/vmsgetargs.c: Vaguely adjust, but who cares?
1350
1351 2001-12-10  Akim Demaille  <akim@epita.fr>
1352
1353         * src/muscle_tab.c (muscle_init): NULL is a better default than
1354         `"0"'.
1355
1356 2001-12-10  Akim Demaille  <akim@epita.fr>
1357
1358         * src/reader.c (reader): Calling symbols_output once is enough.
1359
1360 2001-12-10  Akim Demaille  <akim@epita.fr>
1361
1362         Now that states have a complete set of members, the linked list of
1363         reductions is useless: just fill directly the state's reductions
1364         member.
1365
1366         * src/state.h (struct reductions): Remove member `number' and
1367         `next'.
1368         * src/LR0.c (first_reduction, last_reduction): Remove.
1369         (save_reductions): Don't link the new reductions, store them in
1370         this_state.
1371         * src/lalr.c (set_state_table): No need to attach reductions to
1372         states, it's already done.
1373         * src/output.c (output_actions): No longer free the shifts, then
1374         the reductions, then the states: free all the states and their
1375         members.
1376
1377 2001-12-10  Akim Demaille  <akim@epita.fr>
1378
1379         * src/options.c (OPTN, DRTV, BOTH): New.
1380         (option_table): Use them.
1381
1382         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1383         the job of system.h.
1384         * src/options.c: Don't include stdio.h and xalloc.h for the same
1385         reasons.
1386
1387 2001-12-10  Akim Demaille  <akim@epita.fr>
1388
1389         * src/output.c (output, prepare): Make sure the values of the
1390         muscles `action' and `prologue' are 0-terminated.
1391
1392 2001-12-10  Akim Demaille  <akim@epita.fr>
1393
1394         Clean up GCC warnings.
1395
1396         * src/reader.c (copy_action): `buf' is not used.
1397         (parse_skel_decl): Be static.
1398         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1399         * src/options.h (create_long_option_table): Have a real prototype.
1400         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1401         (hash_delete_at): Return const void *.
1402         Adjust casts to preserve the const.
1403
1404 2001-12-10  Akim Demaille  <akim@epita.fr>
1405
1406         * configure.in: Require 2.52g.
1407         M4 is not needed, but AUTOM4TE is.
1408         * m4/m4.m4: Remove.
1409         * tests/Makefile.am: Adjust.
1410
1411 2001-12-10  Akim Demaille  <akim@epita.fr>
1412
1413         One structure for states is enough, even though theoretically
1414         there are LR(0) states and LALR(1) states.
1415
1416         * src/lalr.h (state_t): Remove.
1417         (state_table): Be state_t **, not state_t *.
1418         * src/state.h (core, CORE_ALLOC): Rename as...
1419         (state_t, STATE_ALLOC): this.
1420         Add the LALR(1) members: shifts, reductions, errs.
1421         * src/LR0.c (state_table): Rename as...
1422         (state_hash): this, to avoid name clashes with the global
1423         `state_table'.
1424         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1425         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
1426
1427 2001-12-10  Akim Demaille  <akim@epita.fr>
1428
1429         Bison dumps core on bash.y.
1430         Reported by Pascal Bart.
1431
1432         * src/warshall.c (bitmatrix_print): New.
1433         (TC): Use it.
1434         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1435         j must be the outer loop.
1436         * tests/regression.at (Broken Closure): New.
1437
1438 2001-12-05  Akim Demaille  <akim@epita.fr>
1439
1440         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1441         its argument.
1442         Reported by Peter Hámorský.
1443
1444 2001-12-05  Akim Demaille  <akim@epita.fr>
1445
1446         * src/conflicts.c (err_table): Remove.
1447         (resolve_sr_conflict): Adjust.
1448         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1449         Rename as...
1450         (state_t.reductions, state_t.shifts): this.
1451
1452 2001-12-05  Akim Demaille  <akim@epita.fr>
1453
1454         * src/reduce.c (reduce_grammar_tables): No longer disable the
1455         removal of useless rules via CPP but via `if (0)', so that the
1456         compiler still check the code is valid.
1457         For instance, it should have noticed `rline' no longer exists: use
1458         the `line' member of rule_t.
1459         * src/gram.c (dummy, rline): Remove, unused.
1460
1461 2001-12-05  Akim Demaille  <akim@epita.fr>
1462
1463         * src/output.c (pack_vector): Use assert, not berror.
1464         * src/main.c (berror): Remove, unused.
1465
1466 2001-12-05  Akim Demaille  <akim@epita.fr>
1467
1468         New experimental feature: if --verbose --trace output all the
1469         items of a state, not only its kernel.
1470
1471         * src/print.c (print_core): If `trace_flag', then invoke closure
1472         before outputting the items of the state (print_core is no longer
1473         a correct name them).
1474         (print_results): Invoke new_closure/free_closure if needed.
1475
1476 2001-12-05  Akim Demaille  <akim@epita.fr>
1477
1478         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1479         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1480         (nitemset): for consistency with the rest of the project.
1481
1482 2001-12-05  Akim Demaille  <akim@epita.fr>
1483
1484         * src/closure.c (print_closure): Improve.
1485         (closure): Use it for printing input and output.
1486
1487 2001-12-05  Akim Demaille  <akim@epita.fr>
1488
1489         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1490         indexed by nonterminals.
1491
1492 2001-12-05  Akim Demaille  <akim@epita.fr>
1493
1494         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1495         what it was!).
1496         * src/warshall.h: Remove accidental duplication of the content.
1497
1498 2001-12-05  Akim Demaille  <akim@epita.fr>
1499
1500         * src/closure.c (set_fderives): De-obfuscate.
1501
1502 2001-12-05  Akim Demaille  <akim@epita.fr>
1503
1504         * src/closure.c (print_firsts, print_fderives): De-obfuscate.
1505
1506 2001-12-05  Akim Demaille  <akim@epita.fr>
1507
1508         * src/closure.c (set_firsts): De-obfuscate.
1509
1510 2001-12-05  Akim Demaille  <akim@epita.fr>
1511
1512         * src/output.c (action_row): De-obfuscate
1513         using the good o' techniques: arrays not pointers, variable
1514         locality, BITISSET, RESETBIT etc.
1515
1516 2001-12-05  Akim Demaille  <akim@epita.fr>
1517
1518         Pessimize the code to simplify it: from now on, all the states
1519         have a valid SHIFTS, which NSHIFTS is possibly 0.
1520
1521         * src/LR0.c (shifts_new): Be global and move to..
1522         * src/state.c, src/state.h: here.
1523         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1524         * src/print_graph: Adjust.
1525
1526 2001-12-05  Akim Demaille  <akim@epita.fr>
1527
1528         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1529         * src/conflicts.c: Use it.
1530         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1531         incorrectly ``simplified''.
1532
1533 2001-12-05  Akim Demaille  <akim@epita.fr>
1534
1535         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1536         using the good o' techniques: arrays not pointers, variable
1537         locality, BITISSET, RESETBIT etc.
1538
1539 2001-12-05  Akim Demaille  <akim@epita.fr>
1540
1541         * src/state.h (SHIFT_SYMBOL): New.
1542         * src/conflicts.c: Use it to deobfuscate.
1543
1544 2001-12-05  Akim Demaille  <akim@epita.fr>
1545
1546         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1547         (print_reductions): De-obfuscate using the good o' techniques:
1548         arrays not pointers, variable locality, BITISSET.
1549
1550 2001-12-05  Akim Demaille  <akim@epita.fr>
1551
1552         * src/conflicts.c (print_reductions): Arrays, not pointers.
1553         Use BITISSET.
1554
1555 2001-12-05  Akim Demaille  <akim@epita.fr>
1556
1557         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1558
1559 2001-12-05  Akim Demaille  <akim@epita.fr>
1560
1561         * src/conflicts.c (print_reductions): Improve variable locality.
1562
1563 2001-12-05  Akim Demaille  <akim@epita.fr>
1564
1565         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1566
1567 2001-12-05  Akim Demaille  <akim@epita.fr>
1568
1569         * src/conflicts.c (print_reductions): Improve variable locality.
1570
1571 2001-12-05  Akim Demaille  <akim@epita.fr>
1572
1573         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
1574         * src/lalr.c: Use them.
1575
1576 2001-12-05  Akim Demaille  <akim@epita.fr>
1577
1578         * src/LR0.c (augment_automaton): Formatting changes.
1579         Better variable locality.
1580
1581 2001-12-05  Akim Demaille  <akim@epita.fr>
1582
1583         * src/lalr.c (matrix_print): New.
1584         (transpose): Use it.
1585         Use arrays instead of pointers.
1586
1587 2001-12-05  Akim Demaille  <akim@epita.fr>
1588
1589         * src/lalr.c (maxrhs): Move to...
1590         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1591         * src/lalr.c (build_relations): Adjust.
1592
1593 2001-12-05  Akim Demaille  <akim@epita.fr>
1594
1595         * src/lalr.c (transpose): Free the memory allocated to the
1596         argument, as it is replaced by the results by the unique caller.
1597         (build_relations): Merely invoke transpose: it handles the memory
1598         deallocation.
1599         Improve variable locality.
1600         Avoid variables used as mere abbreviations.
1601         (compute_lookaheads): Use arrays instead of pointers.
1602
1603 2001-12-05  Akim Demaille  <akim@epita.fr>
1604
1605         * src/lalr.c (initialize_F): Improve variable locality.
1606         Avoid variables used as mere abbreviations.
1607
1608 2001-12-05  Akim Demaille  <akim@epita.fr>
1609
1610         * src/derives.c (print_derives): Display the ruleno.
1611         * src/lalr.c (initialize_F, transpose): Better variable locality
1612         to improve readability.
1613         Avoid variables used as mere abbreviations.
1614
1615 2001-12-05  Akim Demaille  <akim@epita.fr>
1616
1617         * src/lalr.c (traverse): Use arrays instead of pointers.
1618
1619 2001-12-05  Akim Demaille  <akim@epita.fr>
1620
1621         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1622         the handling of squeue.
1623         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1624
1625 2001-12-05  Akim Demaille  <akim@epita.fr>
1626
1627         Because useless nonterminals are now kept alive (instead of being
1628         `destroyed'), we now sometimes examine them, and store information
1629         related to them.  Hence we need to know their number, and adjust
1630         memory allocations.
1631
1632         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1633         static.
1634         * src/LR0.c (allocate_itemsets): The memory allocated to
1635         `symbol_count' was used for two different purpose: once to count
1636         the number of occurrences of each symbol, and later reassigned to
1637         `shift_symbol', containing the symbol that can be shifted from a
1638         given state.
1639         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1640         only, and...
1641         (new_itemsets): Allocate `shift_symbol' here.
1642         (allocate_itemsets): symbol_count includes useless nonterminals.
1643         Make room for them.
1644         (free_storage): Use `free', not `XFREE', for pointers that cannot
1645         be null.
1646
1647 2001-12-05  Akim Demaille  <akim@epita.fr>
1648
1649         * src/nullable.c (set_nullable): Deobfuscate the handling of
1650         ritem.
1651         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1652
1653 2001-12-05  Akim Demaille  <akim@epita.fr>
1654
1655         * src/gram.c, src/gram.h (ritem_print): New.
1656         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1657         (This useless function was defined only to work around VMS linkers
1658         that can't handle compilation units with variables only).
1659         * src/reduce.c (dump_grammar): Use it to trace the construction of
1660         ritem.
1661
1662 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1663
1664         * src/bison.simple (union yyalloc): Change member names
1665         to be the same as the stack names.
1666         (yyparse): yyptr is now union yyalloc *, not char *.
1667         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1668         and may generate better code on some machines.
1669         (yystpcpy): Use prototype if __STDC__ is defined, not just
1670         if __cplusplus is defined.
1671
1672 2001-11-30  Akim Demaille  <akim@epita.fr>
1673
1674         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1675         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1676         Gettext doesn't compile cleanly, and dies with -Werror.
1677         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1678         Include WARNING_CFLAGS here.
1679         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1680         before being defined.
1681
1682 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1683
1684         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1685         First arg is int, not unsigned.
1686         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1687         (SIZE_MAX, UINT_MAX): New macros.
1688         (quotearg_n_options): Abort if N is negative.
1689         Avoid overflow check on hosts where size_t is 64 bits and int
1690         is 32 bits, as overflow is impossible there.
1691         Fix off-by-one typo that caused unnecessary reallocation.
1692
1693 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1694
1695         Name space cleanup in generated parser.
1696
1697         * doc/bison.texinfo (Bison Parser): Discuss system headers
1698         and their effect on the user name space.
1699
1700         * src/bison.simple:
1701         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1702         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1703         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1704
1705         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1706         on user names when possible.
1707
1708         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1709         Simplify test for whather <alloca.h> exists.
1710
1711         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1712
1713         (<stdio.h>): Include if YYDEBUG.
1714
1715         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
1716         ! defined (yyoverflow) && ! defined (yymemcpy).
1717
1718         (yymemcpy, yyparse): Rename local variables as needed so that
1719         they all begin with 'yy'.
1720
1721         (yystrlen, yystpcpy): New functions.
1722
1723         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1724         All uses changed.
1725
1726         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1727         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1728         and YYSTACK_FREE instead of malloc and free.
1729
1730 2001-11-30  Akim Demaille  <akim@epita.fr>
1731
1732         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
1733         before their first uses.
1734         (YYBISON, YYPURE): Move to the top of the output.
1735
1736 2001-11-30  Akim Demaille  <akim@epita.fr>
1737
1738         * tests/reduce.at (Useless Nonterminals): Fix.
1739
1740 2001-11-30  Akim Demaille  <akim@epita.fr>
1741
1742         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1743         if body instead of `;' to pacify GCC's warnings.
1744
1745 2001-11-30  Akim Demaille  <akim@epita.fr>
1746
1747         Instead of mapping the LHS of unused rules to -1, keep the LHS
1748         valid, but flag the rules as invalid.
1749
1750         * src/gram.h (rule_t): `useful' is a new member.
1751         * src/print.c (print_grammar): Adjust.
1752         * src/derives.c (set_derives): Likewise.
1753         * src/reader.c (packgram, reduce_output): Likewise.
1754         * src/reduce.c (reduce_grammar_tables): Likewise.
1755         * tests/reduce.at (Underivable Rules, Useless Rules): New.
1756
1757 2001-11-30  Akim Demaille  <akim@epita.fr>
1758
1759         * src/reduce.c (reduce_output): Formatting changes.
1760         * src/print.c (print_results, print_grammar): Likewise.
1761         * tests/regression.at (Rule Line Numbers)
1762         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
1763
1764 2001-11-30  Akim Demaille  <akim@epita.fr>
1765
1766         * src/reduce.c (nonterminals_reduce): Instead of throwing away
1767         useless nonterminals, move them at the end of the symbol arrays.
1768         (reduce_output): Adjust.
1769         * tests/reduce.at (Useless Nonterminals): Adjust.
1770
1771 2001-11-30  Akim Demaille  <akim@epita.fr>
1772
1773         * src/reduce.c: Various comment/formatting changes.
1774         (nonterminals_reduce): New, extracted from...
1775         (reduce_grammar_tables): here.
1776         (reduce_grammar): Call nonterminals_reduce.
1777
1778 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1779
1780         * src/bison.simple (YYSTACK_REALLOC): Remove.
1781         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
1782         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
1783         New macros.
1784         (union yyalloc): New type.
1785         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1786         an arbitrary restriction on hosts where size_t is wider than int.
1787
1788         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1789         a parser stack overflow.  Allocate just one block of memory for all
1790         three stacks, instead of allocating three blocks; this typically is
1791         faster and reduces fragmentation.
1792
1793         Do not limit the number of items in the stack to a value that fits
1794         in 'int', as this is an arbitrary limit on hosts with 64-bit
1795         size_t and 32-bit int.
1796
1797 2001-11-29  Marc Autret  <autret_m@epita.fr>
1798
1799         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
1800         of defining YYERROR_VERBOSE.
1801         [AT_DATA]: $4 is now out of C declarations in the prologue.
1802
1803 2001-11-28  Marc Autret  <autret_m@epita.fr>
1804
1805         * src/reader.c (parse_dquoted_param): New.
1806         (parse_skel_decl): Use it.
1807         * src/lex.h: Add its prototype.
1808         * src/lex.c (literalchar): Become not static.
1809
1810 2001-11-28  Marc Autret  <autret_m@epita.fr>
1811
1812         * src/output.h: And put its extern declaration here.
1813         * src/output.c (error_verbose): Define here.

2223         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:

3599
3600         * src/conflicts.c (conflict_report): Be sure not to append to res
3601         between two calls, which could happen if both first sprintf were
3602         skipped, but not the first cp += strlen.
3603
3604 2001-02-08  Akim Demaille  <akim@epita.fr>
3605
3606         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
3607         New, from fileutils 4.0.37.
3608         * configure.in: Require Autoconf 2.49c.  I took some time before
3609         making this decision.  This is the only way out for portability
3610         issues in Bison, it would mean way too much duplicate effort to
3611         import in Bison features implemented in 2.49c since 2.13.
3612         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
3613
3614 2001-02-02  Akim Demaille  <akim@epita.fr>

3618
3619 2001-01-19  Akim Demaille  <akim@epita.fr>
3620
3621         Get rid of the ad hoc handling of token_buffer in the scanner: use
3622         the obstacks.
3623
3624         * src/lex.c (token_obstack): New.
3625         (init_lex): Initialize it.  No longer call...
3626         (grow_token_buffer): this.  Remove it.
3627         Adjust all the places which used it to use the obstack.
3628
3629 2001-01-19  Akim Demaille  <akim@epita.fr>
3630
3631         * src/lex.h: Rename all the tokens:
3632         s/\bENDFILE\b/tok_eof/g;
3633         s/\bIDENTIFIER\b/tok_identifier/g;
3634         etc.
3635         Let them be enums, not #define, to ease debugging.
3636         Adjust all the code.
3637
3638 2001-01-18  Akim Demaille  <akim@epita.fr>
3639
3640         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
3641         * src/lex.c (maxtoken, grow_token_buffer): Static.
3642
3643 2001-01-18  Akim Demaille  <akim@epita.fr>
3644
3645         Since we now use obstacks, more % directives can be enabled.
3646
3647         * src/lex.c (percent_table): Also accept `%yacc',
3648         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3649         `%debug'.
3650         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3651         instead of returning a token.
3652         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3653         * src/reader.c (read_declarations): Adjust.
3654         * src/files.c (open_files): Don't call `compute_base_names', don't
3655         compute `attrsfile' since they depend upon data which might be
3656         *in* the input file now.
3657         (output_files): Do it here.
3658         * src/output.c (output_headers): Document the fact that this patch
3659         introduces a guaranteed SEGV for semantic parsers.
3660         * doc/bison.texinfo: Document them.
3661         * tests/suite.at: Exercise these %options.
3662
3663 2000-12-20  Akim Demaille  <akim@epita.fr>
3664
3665         Also handle the output file (--verbose) with obstacks.
3666
3667         * files.c (foutput): Remove.
3668         (output_obstack): New.
3669         Adjust all dependencies.

3677         * src/files.c (open_files): Fix the computation of short_base_name
3678         in the case of `-o foo.tab.c'.
3679

3681
3682         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
3683         (copy_dollar): Now that everything uses obstacks, get rid of the
3684         FILE * parameters.
3685
3686 2000-12-20  Akim Demaille  <akim@epita.fr>
3687
3688         * src/files.c (open_files): Actually the `.output' file is based
3689         on the short_base_name, not base_name.
3690         * tests/suite.at (Checking output file names): Adjust.
3691
3692 2000-12-20  Akim Demaille  <akim@epita.fr>
3693
3694         * src/bison.s1: Remove, we now use directly...
3695         * src/bison.simple: this.
3696         * src/Makefile.am: Use pkgdata instead of data.
3697

3711         (output_files): Adjust.
3712         (base_name, short_base_name): Be global.
3713         Adjust dependencies.
3714
3715 2000-12-19  Akim Demaille  <akim@epita.fr>
3716
3717         * src/files.c (strsuffix): New.
3718         (stringappend): Be just like strcat but allocate.
3719         (base_names): Eve out from open_files.
3720         Try to simplify the rather hairy computation of base_name and
3721         short_base_name.
3722         (open_files): Use it.
3723         * tests/suite.at (Checking output file names): New test.

3730         `$'.

3733
3734 2000-12-19  Akim Demaille  <akim@epita.fr>
3735
3736         * src/output.c (output_parser): Compute the `#line' lines when
3737         there are.
3738         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
3739         Suggested by Hans Aberg.
3740
3741 2000-12-19  Akim Demaille  <akim@epita.fr>
3742
3743         Let the handling of the skeleton files be local to the procedures
3744         that use it.
3745
3746         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
3747         longer static.
3748         (fparser, open_extra_files): Remove.

3760
3761 2000-12-19  Akim Demaille  <akim@epita.fr>
3762
3763         * src/files.c (open_files): Yipee!  We no longer need all the code
3764         looking for `/tmp' since we have no tmp file.
3765
3766 2000-12-19  Akim Demaille  <akim@epita.fr>
3767
3768         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

3794
3795         * lib/obstack.h: Formatting changes.
3796         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3797         prevents type checking.
3798         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3799         cast the value to (void *): assigning a `foo *' to a `void *'
3800         variable is valid.
3801         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3802         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

3837
3838 2000-11-07  Akim Demaille  <akim@epita.fr>
3839
3840         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
3841         Merge in a single CPP if/else.
3842
3843 2000-11-07  Akim Demaille  <akim@epita.fr>
3844

3846         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
3847         argument `data' for consistency with the prototypes.

3850         `address' for consistency.  Qualify it `const'.

3862 2000-11-03  Akim Demaille  <akim@epita.fr>
3863
3864         For some reason, this was not applied.
3865
3866         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

3882         * src/main.c (main): Don't use `atexit' to register `done', since
3883         it no longer has to remove tmp files, just call `output_files'
3884         when there are no errors.
3885
3886 2000-11-02  Akim Demaille  <akim@epita.fr>

3955         * src/reader.c (copy_comment2): Expect the input stream to be on
3956         the `/' which is suspected to open a comment, instead of being
3957         called after `//' or `/*' was read.
3958         (copy_comment, copy_definition, parse_union_decl, copy_action)
3959         (copy_guard): Adjust.

3986
3987 2000-10-04  Akim Demaille  <akim@epita.fr>

3989         When a literal string is used to define two different tokens,
3990         `bison -v' segfaults.
3991         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3992
3993         * tests/regression.m4: New file.
3994         Include the core of the sample provided by Piotr Gackiewicz.
3995         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
3996         properly.
3997
3998 2000-10-04  Akim Demaille  <akim@epita.fr>
3999
4000         * src/reader.c (parse_expect_decl): Keep `count' within the size
4001         of `buffer'.
4002         From Neil Booth.
4003
4004 2000-10-02  Paul Eggert  <eggert@twinsun.com>
4005
4006         * bison.s1 (yyparse): Assign the default value
4007         unconditionally, to avoid a GCC warning and make the parser a
4008         tad smaller.
4009
4010 2000-10-02  Akim Demaille  <akim@epita.fr>
4011
4012         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
4013         options.
4014

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

4125         Adjust dependencies.
4126
4127 2000-10-02  Akim Demaille  <akim@epita.fr>
4128
4129         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4130         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4131         difficult and introduced a lot of core dump.  It turns out that
4132         Bison used an implementation of `xmalloc' based on `calloc', and
4133         at various places it does depend upon the initialization to 0.  I
4134         have not tried to isolate the pertinent places, and all the former
4135         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4136         someone should address this issue.
4137
4138         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4139         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
4140         files.

4151 2000-10-02  Akim Demaille  <akim@epita.fr>
4152

4232
4233         * src/output.c (token_actions): Introduce a temporary array,

4235         output_short_table.
4236
4237 2000-10-02  Akim Demaille  <akim@epita.fr>
4238
4239         `user_toknums' is output as a `short[]' in `output.c', while it is
4240         defined as a `int[]' in `reader.c'.  For consistency with the
4241         other output tables, `user_toknums' is now defined as a table of
4242         shorts.
4243
4244         * src/reader.c (user_toknums): Be a short table instead of an int
4245         table.

4257         order to get rid of the `static' prototypes.
4258         No longer use `register'.
4259         * src/output.h: New file.
4260         Propagate its inclusion in files explicitly prototyping functions
4261         from output.c.

4272         (initialize_closure, finalize_closure):  Rename as...
4273         (new_closure, free_closure): these.  Adjust dependencies.

4283         inclusion.
4284         Don't define PARAMS.
4285         * src/system.h: Define PARAMS.
4286         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
4287         purpose of config.h.  system.h must not try to fix wrong
4288         definitions in config.h.

4313         Let all `extern' declarations about getargs.c be replaced with

4425         * configure.in: Adjust.
4426         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

4450         the file name, not the whole `#line LINE FILE'.
4451
4452 2000-03-17  Akim Demaille  <akim@epita.fr>
4453
4454         On syntax errors, report the token on which we choked.
4455
4456         * src/bison.s1 (yyparse): In the label yyerrlab, when

4474

4476         copy_comment.  Removed now unused `match', `ended',
4477         `cplus_comment'.
4478         (copy_comment, copy_string): Moved, to be visible from
4479         copy_definition.

4482
4483         * src/reader.c (copy_string): Declare `static inline'.  No

4505
4506         Change the handling of @s so that they behave exactly like $s.
4507         There is now a pseudo variable @$ (readble and writable), location
4508         of the lhs of the rule (by default ranging from the location of
4509         the first symbol of the rhs, to the location of the last symbol,
4510         or, if the rhs is empty, YYLLOC).
4511
4512         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4513         yyval.
4514         (yyparse): When providing a default semantic action, provide a
4515         default location action.
4516         (after the $): No longer change `*YYLSP', just stack YYLOC the
4517         same way you stack YYVAL.
4518         * src/reader.c (read_declarations): Use warns.
4519         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4520         (copy_action, case '@'): Likewise.
4521         Use a standard error message, to save useless work from
4522         translators.
4523
4524 2000-03-17  Akim Demaille  <akim@epita.fr>
4525

4543
4544         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4545         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4546         One `#if YYDEBUG' remains, since it uses variables which are
4547         defined only if `YYDEBUG != 0'.
4548
4549 2000-03-16  Akim Demaille  <akim@epita.fr>

4575         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

4581         the proper line number and file name.
4582         (DEFS): Propagate the location of bison library files and of the
4583         locale files.
4584         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4585         builddir.
4586         * acinclude.m4: Remove, replaced by the directory m4.
4587         * m4/Makefile.am (EXTRA_DIST): New variable.

5275         major changes to files.c.
