ChangeLog

   1 2002-02-28  Akim Demaille  <akim@epita.fr>
   2
   3         * data/bison.c++: Copy the prologue of bison.simple to fetch
   4         useful M4 definitions, such as b4_header_guard.
   5
   6 2002-02-25  Akim Demaille  <akim@epita.fr>
   7
   8         * src/getargs.c (version): Give the name of the authors, and use a
   9         translator friendly scheme for the bgr
  10         copyright notice.
  11
  12 2002-02-25  Akim Demaille  <akim@epita.fr>
  13
  14         * src/output.c (header_output): Remove, now handled completely via
  15         M4.
  16
  17 2002-02-25  Akim Demaille  <akim@epita.fr>
  18
  19         * m4/m4.m4: New, from CVS Autoconf.
  20         * configure.in: Invoke it.
  21         * src/output.c (output_skeleton): Use its result instead of the
  22         hard coded name.
  23
  24 2002-02-25  Akim Demaille  <akim@epita.fr>
  25
  26         * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
  27         Fileutils 4.1.5.
  28         * configure.in: Invoke UTILS_FUNC_MKSTEMP.
  29         * src/output.c (output_skeleton): Use mkstemp to create a real
  30         temporary file.
  31         Move the filling of `skeleton' and its muscle to...
  32         (prepare): here.
  33         (output): Move the definition of the prologue muscle to...
  34         (prepare): here.
  35         * src/system.h (DEFAULT_TMPDIR): New.
  36
  37 2002-02-14  Paul Eggert  <eggert@twinsun.com>
  38
  39         Remove the support for C++ namespace cleanliness; it was
  40         causing more problems than it was curing, since it didn't work
  41         properly on some nonstandard C++ compilers.  This can wait
  42         for a proper C++ parser.
  43
  44         * NEWS: Document this.
  45         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
  46         of C++, as it's treated like C now.
  47         * src/bison.simple (YYSTD): Remove.
  48         (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
  49         Treat C++ just like Standard C instead of trying to support
  50         namespace cleanliness.
  51
  52 2002-02-14  Akim Demaille  <akim@epita.fr>
  53
  54         * tests/regression.at (else): Adjust to Andreas' change.
  55
  56 2002-02-14  Akim Demaille  <akim@epita.fr>
  57
  58         * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
  59
  60 2002-02-13  Andreas Schwab  <schwab@suse.de>
  61
  62         * src/output.c (output_rule_data): Don't output NULL, it might
  63         not be defined yet.
  64
  65 2002-02-11  Robert Anisko  <robert@lrde.epita.fr>
  66
  67         * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
  68         (Copyright notice): Update.
  69
  70 2002-02-11  Akim Demaille  <akim@epita.fr>
  71
  72         * tests/regression.at (%nonassoc and eof): Don't include
  73         nonportable headers.
  74
  75 2002-02-08  Robert Anisko  <robert@lrde.epita.fr>
  76
  77         * data/bison.c++: Correct error recovery.  Make the user able to
  78         initialize the starting location.
  79
  80 2002-02-07  Akim Demaille  <akim@epita.fr>
  81
  82         * tests/input.at: New.
  83
  84 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
  85
  86         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
  87         more consistent when naming methods and variables.  Put preprocessor
  88         directives around tables only needed for debugging.
  89
  90 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
  91
  92         * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
  93         C++ parsers.
  94         (yy::b4_name::parse): Use print_.
  95
  96 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
  97
  98         * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
  99
 100 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 101
 102         * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
 103         C++ parsers.
 104         (yy::b4_name::parse): Build verbose error messages, and use error_.
 105
 106 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
 107
 108         * data/bison.c++: Fix m4 quoting in comments.
 109
 110 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
 111
 112         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
 113         not expanded by m4.
 114
 115 2002-02-05  Akim Demaille  <akim@epita.fr>
 116
 117         * data/bison.c++: Adjust to the M4 back end.
 118         More is certainly needed.
 119
 120 2002-02-05  Akim Demaille  <akim@epita.fr>
 121
 122         Give a try to M4 as a back end.
 123
 124         * lib/readpipe.c: New, from wdiff.
 125         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
 126         BISON_HAIRY.
 127         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
 128         specific values.  Now it is m4 that performs the lookup.
 129         * src/parse-skel.y: Remove.
 130         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
 131         * src/output.c (actions_output, guards_output)
 132         (token_definitions_output): No longer keeps track of the output
 133         line number, hence remove the second argument.
 134         (guards_output): Check against the guard member of a rule, not the
 135         action member.
 136         Adjust callers.
 137         (output_skeleton): Don't look for the skeleton location, let m4 do
 138         that.
 139         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
 140         file will be used.
 141         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
 142         (prepare): Given that for the time being changesyntax is not
 143         usable in M4, rename the muscles using `-' to `_'.
 144         Define `defines_flag', `output_parser_name' and `output_header_name'.
 145         * src/output.h (actions_output, guards_output)
 146         (token_definitions_output): Adjust prototypes.
 147         * src/scan-skel.l: Instead of scanning the skeletons, it now
 148         processes the output of m4: `__oline__' and `#output'.
 149         * data/bison.simple: Adjust to be used by M4(sugar).
 150         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
 151         to date.
 152         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
 153         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
 154         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
 155         shamelessly stolen from CVS Autoconf.
 156
 157 2002-02-05  Akim Demaille  <akim@epita.fr>
 158
 159         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
 160         * configure.in: Check for the declarations of free and malloc.
 161         * src/muscle_tab.c: Adjust.
 162
 163 2002-02-05  Akim Demaille  <akim@epita.fr>
 164
 165         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
 166         which have no values.
 167
 168 2002-02-05  Akim Demaille  <akim@epita.fr>
 169
 170         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
 171         * data/: here.
 172
 173 2002-01-29  Paul Eggert  <eggert@twinsun.com>
 174
 175         * src/bison.simple (YYSIZE_T): Do not define merely because
 176         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 177         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 178
 179 2002-01-27  Akim Demaille  <akim@epita.fr>
 180
 181         Fix `%nonassoc and eof'.
 182
 183         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
 184         which were not properly copied!  Replace
 185         memcpy (res->errs, src->errs, src->nerrs);
 186         with
 187         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
 188         !!!
 189         * tests/regression.at (%nonassoc and eof): Adjust to newest
 190         Autotest: `.' is not in the PATH.
 191
 192 2002-01-27  Akim Demaille  <akim@epita.fr>
 193
 194         * tests/sets.at (AT_EXTRACT_SETS): New.
 195         (Nullable): Use it.
 196         (Firsts): New.
 197
 198 2002-01-26  Akim Demaille  <akim@epita.fr>
 199
 200         * tests/actions.at, tests/calc.at, tests/headers.at,
 201         * tests/torture.at: Adjust to the newest Autotest which no longer
 202         forces `.' in the PATH.
 203
 204 2002-01-25  Akim Demaille  <akim@epita.fr>
 205
 206         * tests/regression.at (%nonassoc and eof): New.
 207         Suggested by Robert Anisko.
 208
 209 2002-01-24  Akim Demaille  <akim@epita.fr>
 210
 211         Bison dumps core when trying to complain about broken input files.
 212         Reported by Cris van Pelt.
 213
 214         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
 215         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
 216         into...
 217         (Invalid inputs): Strengthen: exercise parse_percent_token.
 218
 219 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
 220
 221         * src/Makefile.am: Add bison.c++.
 222         * src/bison.c++: New skeleton.
 223
 224 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
 225
 226         * po/it.po: New.
 227
 228 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>

 230         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
 231
 232 2002-01-20  Marc Autret  <marc@gnu.org>
 233
 234         * src/files.c (compute_output_file_names): Fix
 235
 236 2002-01-20  Marc Autret  <marc@gnu.org>
 237
 238         * tests/output.at: New test.
 239         * src/files.c (compute_base_names): Don't map extensions when
 240         the YACC flag is set, use defaults.
 241         Reported by Evgeny Stambulchik.
 242
 243 2002-01-20  Marc Autret  <marc@gnu.org>
 244
 245         * src/system.h: Need to define __attribute__ away for non-GCC
 246         compilers as well (i.e. the vendor C compiler).
 247         Suggested by Albert Chin-A-Young.
 248
 249 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
 250
 251         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
 252         canonical definition.
 253         * src/system.h: Use the canonical definition for PARAMS (avoids
 254         a conflict with the macro from lib/hash.h).
 255
 256 2002-01-11  Akim Demaille  <akim@epita.fr>
 257
 258         * configure.in: Use AC_FUNC_STRNLEN.
 259         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
 260
 261 2002-01-09  Akim Demaille  <akim@epita.fr>
 262
 263         * src/files.c, src/files.h (output_infix): New.
 264         (tab_extension): Remove.
 265         (compute_base_names): Compute the former, drop the latter.
 266         * src/output.c (prepare): Insert the muscles `output-infix', and
 267         `output-suffix'.
 268         * src/parse-skel.y (string, string.1): New.
 269         (section.header): Use it.
 270         (section.yacc): Remove.
 271         (prefix): Remove too.
 272         * src/scan-skel.l: Adjust.
 273         * src/bison.simple, src/bison.hairy: Adjust.
 274
 275 2002-01-09  Akim Demaille  <akim@epita.fr>
 276
 277         * configure.in (WERROR_CFLAGS): Compute it.
 278         * src/Makefile.am (CFLAGS): Pass it.
 279         * tests/atlocal.in (CFLAGS): Idem.

 283 2002-01-08  Akim Demaille  <akim@epita.fr>
 284
 285         * src/getargs.c (AS_FILE_NAME): New.
 286         (getargs): Use it to convert DOSish file names.
 287         * src/files.c (base_name): Rename as full_base_name to avoid
 288         clashes with `base_name ()'.
 289         (filename_split): New.
 290         (compute_base_names): N-th rewrite, using filename_split.
 291
 292 2002-01-08  Akim Demaille  <akim@epita.fr>
 293
 294         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
 295         New, stolen from the Fileutils 4.1.
 296         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
 297         * configure.in: Check for the presence of memrchr, and of its

 299
 300 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
 301
 302         * lib/hash.h (__P): Added definition for this macro.
 303         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
 304         BUILT_SOURCES, to ensure they are generated first.
 305         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
 306         %error-verbose to allow bootstrapping with bison 1.30x.
 307
 308 2002-01-06  Akim Demaille  <akim@epita.fr>
 309
 310         * src/reader.c (parse_braces): Don't fetch the next char, the
 311         convention is to fetch on entry.
 312         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
 313         'switch' without a following semicolon.
 314         * tests/regression.at (braces parsing): New.
 315
 316 2002-01-06  Akim Demaille  <akim@epita.fr>
 317
 318         Bison is dead wrong in its RR conflict reports.
 319
 320         * tests/torture.at (GNU Cim Grammar): New.
 321         * src/conflicts.c (count_rr_conflicts): Fix.
 322
 323 2002-01-06  Akim Demaille  <akim@epita.fr>
 324
 325         Creating package.m4 from configure.ac causes too many problems.
 326
 327         * tests/Makefile.am (package.m4): Create it by hand,
 328         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
 329
 330 2002-01-06  Akim Demaille  <akim@epita.fr>
 331
 332         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
 333         skeleton.h.
 334
 335 2002-01-04  Paul Eggert  <eggert@twinsun.com>
 336
 337         * doc/bison.texinfo (Debugging):
 338         Remove YYSTDERR; it's no longer defined or used.
 339         Also, s/cstdio.h/cstdio/.
 340
 341 2002-01-03  Akim Demaille  <akim@epita.fr>
 342
 343         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
 344
 345 2002-01-03  Akim Demaille  <akim@epita.fr>
 346
 347         * src/parse-skel.y (process_skeleton): Don't bind the parser's
 348         tracing code to --trace, wait for a better --trace option, with
 349         args.
 350
 351 2002-01-03  Akim Demaille  <akim@epita.fr>
 352
 353         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
 354         The ISO C++ standard is extremely clear about it: stderr is
 355         considered a macro, not a regular symbol (see table 94 `Header
 356         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
 357         Therefore std:: does not apply to it.  It still does with fprintf.
 358         Also, s/cstdio.h/cstdio/.
 359
 360 2002-01-03  Akim Demaille  <akim@epita.fr>
 361
 362         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
 363         for non system headers.
 364
 365 2002-01-02  Akim Demaille  <akim@epita.fr>
 366
 367         Equip the skeleton chain with location tracking, runtime trace,
 368         pure parser and scanner.
 369
 370         * src/parse-skel.y: Request a pure parser, locations, and prefix
 371         renaming.
 372         (%union): Having several members with the same type does not help
 373         type mismatches, simplify.
 374         (YYPRINT, yyprint): New.
 375         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
 376         (skel_error): this.
 377         Handle locations.
 378         * src/scan-skel.l: Adjust to these changes.
 379         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
 380         (LOCATION_PRINT, skel_control_t): New.
 381
 382 2001-12-30  Akim Demaille  <akim@epita.fr>
 383
 384         * src/parse-skel.y: Get rid of the shift/reduce conflict:
 385         replace `gb' with BLANKS.
 386         * src/scan-skel.l: Adjust.
 387
 388 2001-12-30  Akim Demaille  <akim@epita.fr>
 389
 390         * src/system.h: We don't need nor want bcopy.
 391         Throw away MS-DOS crap: we don't need getpid.
 392         * configure.in: We don't need strndup.  It was even causing
 393         problems: because Flex includes the headers *before* us,
 394         _GNU_SOURCE is not defined by config.h, and therefore strndup was
 395         not visible.
 396         * lib/xstrndup.c: New.
 397         * src/scan-skel.l: Use it.
 398         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
 399         * src/parse-skel.y: Use %directives instead of #defines.
 400
 401 2001-12-30  Akim Demaille  <akim@epita.fr>
 402
 403         * src/skeleton.h: New.
 404         * src/output.c (output_parser, output_master_parser): Remove, dead
 405         code.
 406         * src/output.h (get_lines_number, actions_output, guards_output)
 407         (token_definitions_output): Prototype them.
 408         * src/parse-skel.y: Add the license notice.
 409         Include output.h and skeleton.h.
 410         (process_skeleton): Returns void, and takes a single parameter.
 411         * src/scan-skel.l: Add the license notice.
 412         Include skeleton.h.
 413         Don't use %option yylineno: it seems that then Flex imagines
 414         REJECT has been used, and therefore it won't reallocate its
 415         buffers (which makes no other sense to me than a bug).  It results
 416         in warnings for `unused: yy_flex_realloc'.
 417
 418 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
 419
 420         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 421         (MUSCLE_INSERT_PREFIX): ...to there.
 422         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 423         (MUSCLE_INSERT_PREFIX): Move from here...
 424
 425         * src/bison.hairy: Add a section directive.  Put braces around muscle
 426         names.  This parser skeleton is still broken, but Bison should not
 427         choke on a bad muscle 'syntax'.
 428         * src/bison.simple: Add a section directive.  Put braces around muscle
 429         names.
 430
 431         * src/files.h (strsuffix, stringappend): Add declarations.
 432         (tab_extension): Add declaration.
 433         (short_base_name): Add declaration.
 434
 435         * src/files.c (strsuffix, stringappend): No longer static.  These
 436         functions are used in the skeleton parser.
 437         (tab_extension): New.
 438         (compute_base_names): Use the computations done in this function
 439         to guess if the generated parsers should have '.tab' in their
 440         names.
 441         (short_base_name): No longer static.
 442
 443         * src/output.c (output_skeleton): New.
 444         (output): Disable call to output_master_parser, and give a try to
 445         a new skeleton handling system.
 446         (guards_output, actions_output): No longer static.
 447         (token_definitions_output, get_lines_number): No longer static.
 448
 449         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
 450
 451         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
 452         parse-skel.y.
 453
 454         * src/parse-skel.y: New file.
 455         * src/scan-skel.l: New file.
 456
 457 2001-12-29  Akim Demaille  <akim@epita.fr>
 458
 459         %name-prefix is broken.
 460
 461         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
 462         Adjust all dependencies.
 463         * tests/headers.at (export YYLTYPE): Strengthen this test: use
 464         %name-prefix.
 465
 466         Renaming yylval but not yylloc is not consistent.  Now we do.
 467
 468         * src/bison.simple: Prefix yylloc if used.
 469         * doc/bison.texinfo (Decl Summary): Document that.
 470
 471 2001-12-29  Akim Demaille  <akim@epita.fr>
 472
 473         * doc/bison.texinfo: Promote `%long-directive' over
 474         `%long_directive'.
 475         Remove all references to fixed-output-files, yacc is enough.
 476
 477 2001-12-29  Akim Demaille  <akim@epita.fr>
 478
 479         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
 480         user prologue.  These are defaults.
 481         * tests/actions.at (Mid-rule actions): Make sure the user can
 482         define YYDEBUG and YYERROR_VERBOSE.
 483
 484 2001-12-29  Akim Demaille  <akim@epita.fr>
 485
 486         * src/output.c (header_output): Don't forget to export YYLTYPE and
 487         yylloc.
 488         * tests/headers.at (export YYLTYPE): New, make sure it does.
 489         * tests/regression.at (%union and --defines, Invalid CPP headers):
 490         Move to...
 491         * tests/headers.at: here.
 492
 493 2001-12-29  Akim Demaille  <akim@epita.fr>
 494
 495         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
 496
 497 2001-12-29  Akim Demaille  <akim@epita.fr>
 498
 499         * tests/actions.at (Mid-rule actions): Output on a single line
 500         instead of several.
 501
 502 2001-12-29  Akim Demaille  <akim@epita.fr>
 503
 504         * doc/bison.texinfo: Formatting changes.
 505
 506 2001-12-29  Akim Demaille  <akim@epita.fr>
 507
 508         Don't store the token defs in a muscle, just be ready to output it
 509         on command.  Now possible via `symbols'.  Fixes a memory leak.
 510
 511         * src/output.c (token_definitions_output): New.
 512         (output_parser, header_output): Use it.
 513         * src/reader.c (symbols_save): Remove.
 514
 515 2001-12-29  Akim Demaille  <akim@epita.fr>
 516
 517         * src/bison.simple: Do not provide a default for YYSTYPE and
 518         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
 519         default.
 520
 521 2001-12-29  Akim Demaille  <akim@epita.fr>
 522
 523         Mid-rule actions are simply... ignored!
 524
 525         * src/reader.c (readgram): Be sure to attach mid-rule actions to
 526         the empty-rule associated to the dummy symbol, not to the host
 527         rule.
 528         * tests/actions.at (Mid-rule actions): New.
 529
 530 2001-12-29  Akim Demaille  <akim@epita.fr>
 531
 532         Memory leak.
 533
 534         * src/reader.c (reader): Free grammar.
 535
 536 2001-12-29  Akim Demaille  <akim@epita.fr>
 537
 538         Memory leak.
 539
 540         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
 541         since it allocates it for each state, although only one is needed.
 542         (allocate_storage): Do it here.
 543
 544 2001-12-29  Akim Demaille  <akim@epita.fr>
 545
 546         * src/options.h, src/options.c (create_long_option_table): Rename
 547         as...
 548         (long_option_table_new): this, with a clearer prototype.
 549         (percent_table): Remove, unused,
 550         * src/getargs.c (getargs): Adjust.
 551
 552 2001-12-29  Akim Demaille  <akim@epita.fr>
 553
 554         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
 555         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 556         as states.
 557
 558 2001-12-29  Akim Demaille  <akim@epita.fr>
 559
 560         * src/lalr.c (build_relations): Rename `states' as `states1'.
 561         Sorry, I don't understand exactly what it is, no better name...
 562
 563 2001-12-29  Akim Demaille  <akim@epita.fr>
 564
 565         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 566         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 567         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 568         as rules.
 569
 570 2001-12-29  Akim Demaille  <akim@epita.fr>
 571
 572         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 573         ago.
 574
 575 2001-12-29  Akim Demaille  <akim@epita.fr>
 576
 577         * src/reader.c, src/reader.h (user_toknums): Remove.
 578         Adjust all users to use symbols[i]->user_token_number.
 579
 580 2001-12-29  Akim Demaille  <akim@epita.fr>
 581
 582         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 583         Adjust all users to use symbols[i]->prec or ->assoc.
 584
 585 2001-12-29  Akim Demaille  <akim@epita.fr>
 586
 587         * src/reader.c, src/reader.h (tags): Remove.
 588         Adjust all users to use symbols[i]->tag.
 589
 590 2001-12-29  Akim Demaille  <akim@epita.fr>
 591
 592         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 593         and rule_table.
 594         * src/reader.c (packsymbols): Fill this table.
 595         Drop sprec.
 596         * src/conflicts.c (resolve_sr_conflict): Adjust.
 597         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 598         single table.
 599         Use symbols[i]->tag instead of tags[i].
 600
 601 2001-12-29  Akim Demaille  <akim@epita.fr>
 602
 603         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 604         In addition, put a comment in there, to replace...
 605         * tests/regression.at (%union and C comments): Remove.
 606
 607 2001-12-29  Akim Demaille  <akim@epita.fr>
 608
 609         * tests/regression.at (Web2c Actions): Blindly move the actual
 610         output as expected output.  The contents *seem* right to me, but I
 611         can't pretend reading perfectly parser tables...  Nonetheless, all
 612         the other tests pass correctly, the table look OK, even though the
 613         presence of `$axiom' is to be noted: AFAICS it is useless (but
 614         harmless).
 615
 616 2001-12-29  Akim Demaille  <akim@epita.fr>
 617
 618         * src/reader.c (readgram): Don't add the rule 0 if there were no
 619         rules read.  In other words, add it _after_ having performed
 620         grammar sanity checks.
 621         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 622
 623 2001-12-29  Akim Demaille  <akim@epita.fr>
 624
 625         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 626         visible, and some states have now a different number.
 627
 628 2001-12-29  Akim Demaille  <akim@epita.fr>
 629
 630         * src/reader.c (readgram): Bind the initial rule's lineno to that
 631         of the first rule.
 632         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 633         (Solved SR Conflicts): Adjust rule 0's line number.
 634
 635 2001-12-29  Akim Demaille  <akim@epita.fr>
 636
 637         Fix the `GAWK Grammar' failure.
 638
 639         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 640         the reductions of the first state which was mistakenly confused
 641         with the final state because precisely final_state was initialized
 642         to 0.
 643         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 644         now noticed by Bison.
 645         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 646         have a reduction on $default.
 647
 648 2001-12-29  Akim Demaille  <akim@epita.fr>
 649
 650         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 651         rule line numbers.
 652         * src/closure.c (print_closure): Likewise.
 653         * src/derives.c (print_derives): Likewise.
 654         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 655         now.
 656
 657 2001-12-29  Akim Demaille  <akim@epita.fr>
 658
 659         * src/lalr.c (lookaheads_print): New.
 660         (lalr): Call it when --trace-flag.
 661         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 662         are dumped.
 663
 664 2001-12-29  Akim Demaille  <akim@epita.fr>
 665
 666         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 667         when walking through ritem, even via rule->rhs.
 668         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 669         (useful_production, useless_nonterminals): Likewise.
 670         (reduce_grammar_tables): Likewise, plus update nritems.
 671         * src/nullable.c (set_nullable): Likewise.
 672         * src/lalr.c (build_relations): Likewise.
 673         * tests/sets.at (Nullable): Adjust.
 674         Fortunately, now, the $axiom is no longer nullable.
 675
 676 2001-12-29  Akim Demaille  <akim@epita.fr>
 677
 678         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 679         the 0-sentinel.
 680         * src/gram.c (ritem_longest_rhs): Likewise.
 681         * src/reduce.c (nonterminals_reduce): Likewise.
 682         * src/print_graph.c (print_graph): Likewise.
 683         * src/output.c (output_rule_data): Likewise.
 684         * src/nullable.c (set_nullable):  Likewise.
 685
 686 2001-12-29  Akim Demaille  <akim@epita.fr>
 687
 688         * src/output.c: Comment changes.
 689
 690 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 691
 692         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 693         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 694         Sparc, as they were causing more porting problems than the
 695         (minor) performance improvement was worth.
 696
 697         Also, catch up with 1.31's YYSTD.
 698
 699 2001-12-27  Akim Demaille  <akim@epita.fr>
 700
 701         * src/output.c (output_gram): Rely on nritems, not the
 702         0-sentinel.  See below.
 703         Use -1 as separator, not 0.
 704         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 705         Rely on -1 as separator in yyrhs, instead of 0.
 706         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 707         twice `Now at end of input', therefore there are two lines less to
 708         expect.
 709
 710 2001-12-27  Akim Demaille  <akim@epita.fr>
 711
 712         * tests/regression.at (Unresolved SR Conflicts):
 713         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 714         below.
 715
 716 2001-12-27  Akim Demaille  <akim@epita.fr>
 717
 718         * src/LR0.c (new_state): Recognize the final state by the fact it
 719         is reached by eoftoken.
 720         (insert_start_shifting_state, insert_eof_shifting_state)
 721         (insert_accepting_state, augment_automaton): Remove, since now
 722         these states are automatically computed from the initial state.
 723         (generate_states): Adjust.
 724         * src/print.c: When reporting a rule number to the user, substract
 725         1, so that the axiom rule is rule 0, and the first user rule is 1.
 726         * src/reduce.c: Likewise.
 727         * src/print_graph.c (print_core): For the time being, just as for
 728         the report, depend upon --trace-flags to dump the full set of
 729         items.
 730         * src/reader.c (readgram): Once the grammar read, insert the rule
 731         0: `$axiom: START-SYMBOL $'.
 732         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 733         number of the states has changed (the final state is no longer
 734         necessarily the last), catch up.
 735
 736 2001-12-27  Akim Demaille  <akim@epita.fr>
 737
 738         Try to make the use of the eoftoken valid.  Given that its value
 739         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 740         is used instead of > 0 where appropriate, (ii), depend upon nritems
 741         instead of the 0-sentinel.
 742
 743         * src/gram.h, src/gram.c (nritems): New.
 744         Expected to be duplication of nitems, but for the time being...
 745         * src/reader.c (packgram): Assert nritems and nitems are equal.
 746         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 747         * src/closure.c (print_closure, print_fderives): Likewise.
 748         * src/gram.c (ritem_print): Likewise.
 749         * src/print.c (print_core, print_grammar): Likewise.
 750         * src/print_graph.c: Likewise.
 751
 752 2001-12-27  Akim Demaille  <akim@epita.fr>
 753
 754         * src/main.c (main): If there are complains after grammar
 755         reductions, then output the report anyway if requested, then die.
 756         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 757         * src/reader.c (eoftoken): New.
 758         (parse_token_decl): If the token being defined has value `0', it
 759         is the eoftoken.
 760         (packsymbols): No longer hack `tags' to insert `$' by hand.
 761         Be sure to preserve the value of the eoftoken.
 762         (reader): Make sure eoftoken is defined.
 763         Initialize nsyms to 0: now eoftoken is created just like the others.
 764         * src/print.c (print_grammar): Don't special case the eof token.
 765         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 766         lie anyway, albeit pleasant.
 767         * tests/calc.at: Exercise error messages with eoftoken.
 768         Change the grammar so that empty input is invalid.
 769         Adjust expectations.
 770         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 771
 772 2001-12-27  Akim Demaille  <akim@epita.fr>
 773
 774         * configure.in: Check the protos of strchr ans strspn.
 775         Replace strchr if needed.
 776         * src/system.h: Provide the protos of strchr, strspn and memchr if
 777         missing.
 778         * lib/strchr.c: New.
 779         * src/reader.c (symbols_save): Use strchr.
 780
 781 2001-12-27  Akim Demaille  <akim@epita.fr>
 782
 783         * src/print.c, src/print_graph.c (escape): New.
 784         Use it to quote the TAGS outputs.
 785         * src/print_graph.c (print_state): Now errors are in red, and
 786         reductions in green.
 787         Prefer high to wide: output the state number on a line of its own.
 788
 789 2001-12-27  Akim Demaille  <akim@epita.fr>
 790
 791         * src/state.h, src/state.c (reductions_new): New.
 792         * src/LR0.c (set_state_table): Let all the states have a
 793         `reductions', even if reduced to 0.
 794         (save_reductions): Adjust.
 795         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 796         * src/print.c (print_reductions, print_actions): Adjust.
 797         * src/output.c (action_row): Adjust.
 798
 799 2001-12-27  Akim Demaille  <akim@epita.fr>
 800
 801         * src/state.h, src/state.c (errs_new, errs_dup): New.
 802         * src/LR0.c (set_state_table): Let all the states have an errs,
 803         even if reduced to 0.
 804         * src/print.c (print_errs, print_reductions): Adjust.
 805         * src/output.c (output_actions, action_row): Adjust.
 806         * src/conflicts.c (resolve_sr_conflict): Adjust.
 807
 808 2001-12-27  Akim Demaille  <akim@epita.fr>
 809
 810         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 811
 812 2001-12-27  Akim Demaille  <akim@epita.fr>
 813
 814         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 815         * src/print.c: here.
 816         (lookaheadset, shiftset): New, used as additional storage by
 817         print_reductions.
 818         (print_results): Adjust.
 819         (print_shifts, print_gotos, print_errs): New, extracted from...
 820         (print_actions): here.
 821         * src/print_graph.c (print_actions): Remove dead code.
 822
 823 2001-12-27  Akim Demaille  <akim@epita.fr>
 824
 825         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 826         `$n' and `@n'.
 827
 828 2001-12-27  Akim Demaille  <akim@epita.fr>
 829
 830         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 831         (build_relations): Adjust.
 832
 833 2001-12-27  Akim Demaille  <akim@epita.fr>
 834
 835         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 836         duplication.
 837
 838 2001-12-27  Akim Demaille  <akim@epita.fr>
 839
 840         * src/reader.c (packgram): Catch nitems overflows.
 841
 842 2001-12-27  Akim Demaille  <akim@epita.fr>
 843
 844         * src/files.c, src/files.h (guard_obstack): Remove.
 845         * src/output.c (output): Adjust.
 846         * src/reader.c (parse_braces): New, factoring...
 847         (copy_action, copy_guard): these two which are renamed as...
 848         (parse_action, parse_guard): these.
 849         As a voluntary consequence, using braces around guards is now
 850         mandatory.
 851
 852 2001-12-27  Akim Demaille  <akim@epita.fr>
 853
 854         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 855         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 856         members.
 857         (symbol_list_new): Adjust.
 858         (copy_action): action_line is the first line, not the last.
 859         (copy_guard): Just as for actions, store the `action' only, not
 860         the switch/case/break flesh.
 861         Don't parse the user action that might follow the guard, let...
 862         (readgram): do it, i.e., now, there can be an action after a
 863         guard.
 864         In other words the guard is just explicitly optional.
 865         (packgram): Adjust.
 866         * src/output.c (guards_output): New.
 867         (output_parser): Call it when needed.
 868         (output): Also free the guard and attrs obstacks.
 869         * src/files.c, src/files.h (obstack_save): Remove.
 870         (output_files): Remove.
 871         As a result, if one needs the former `.act' file, using an
 872         appropriate skeleton which requires actions and guards is now
 873         required.
 874         * src/main.c (main): Adjust.
 875         * tests/semantic.at: New.
 876         * tests/regression.at: Use `input.y' as input file name.
 877         Avoid 8+3 problems by requiring input.c when the test needs the
 878         parser.
 879
 880 2001-12-27  Akim Demaille  <akim@epita.fr>
 881
 882         * src/reader.c (symbol_list_new): Be sure to initialize all the
 883         fields.
 884
 885 2001-12-27  Akim Demaille  <akim@epita.fr>
 886
 887         All the hacks using a final pseudo state are now useless.
 888
 889         * src/LR0.c (set_state_table): state_table holds exactly nstates.
 890         * src/lalr.c (nLA): New.
 891         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
 892         instead of lookaheadsp from the pseudo state (nstate + 1).
 893
 894 2001-12-27  Akim Demaille  <akim@epita.fr>
 895
 896         * src/output.c (action_row, token_actions): Use a state_t instead
 897         of a integer, and nlookaheads instead of the following state's
 898         lookaheadsp.
 899
 900 2001-12-27  Akim Demaille  <akim@epita.fr>
 901
 902         * src/conflicts.c (log_resolution, flush_shift)
 903         (resolve_sr_conflict, set_conflicts, solve_conflicts)
 904         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
 905         (conflicts_print, print_reductions): Use a state_t instead of an
 906         integer when referring to a state.
 907         As much as possible, depend upon nlookaheads, instead of the
 908         `lookaheadsp' member of the following state (since lookaheads of
 909         successive states are successive, the difference between state n + 1
 910         and n served as the number of lookaheads for state n).
 911         * src/lalr.c (add_lookback_edge): Likewise.
 912         * src/print.c (print_core, print_actions, print_state)
 913         (print_results): Likewise.
 914         * src/print_graph.c (print_core, print_actions, print_state)
 915         (print_graph): Likewise.
 916         * src/conflicts.h: Adjust.
 917
 918 2001-12-27  Akim Demaille  <akim@epita.fr>
 919
 920         * src/bison.hairy: Formatting/comment changes.
 921         ANSIfy.
 922         Remove `register' indications.
 923         Add plenty of `static'.
 924
 925 2001-12-27  Akim Demaille  <akim@epita.fr>
 926
 927         * src/output.c (prepare): Drop the muscle `ntbase' which
 928         duplicates ntokens.
 929         * src/bison.simple: Formatting/comment changes.
 930         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
 931         is an undocumented synonym.
 932
 933 2001-12-22  Akim Demaille  <akim@epita.fr>
 934
 935         * src/output.c (output_table_data): Change the prototype to use
 936         `int' for array ranges: some invocations do pass an int, not a
 937         short.
 938         Reported by Wayne Green.
 939
 940 2001-12-22  Akim Demaille  <akim@epita.fr>
 941
 942         Some actions of web2c.y are improperly triggered.
 943         Reported by Mike Castle.
 944
 945         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
 946         * tests/regression.at (Web2c): Rename as...
 947         (Web2c Report): this.
 948         (Web2c Actions): New.
 949
 950 2001-12-22  Akim Demaille  <akim@epita.fr>
 951
 952         Reductions in web2c.y are improperly reported.
 953         Reported by Mike Castle.
 954
 955         * src/conflicts.c (print_reductions): Fix.
 956         * tests/regression.at (Web2c): New.
 957
 958 2001-12-18  Akim Demaille  <akim@epita.fr>
 959
 960         Some host fail on `assert (!"foo")', which expands to
 961         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
 962         Reported by Nelson Beebee.
 963
 964         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
 965         `#define it_succeeded 0' and `assert (it_succeeded)'.
 966
 967 2001-12-17  Marc Autret  <autret_m@epita.fr>
 968
 969         * src/bison.simple: Don't hard code the skeleton line and filename.
 970         * src/output.c (output_parser): Rename 'line' as 'output_line'.
 971         New line counter 'skeleton_line' (skeleton-line muscle).
 972
 973 2001-12-17  Paul Eggert  <eggert@twinsun.com>
 974
 975         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
 976         YYDEBUG must be defined to a nonzero value.
 977
 978         * src/bison.simple (yytname): Do not assume that the user defines
 979         YYDEBUG to a properly parenthesized expression.
 980
 981 2001-12-17  Akim Demaille  <akim@epita.fr>
 982
 983         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
 984         nlookaheads is a new member.
 985         Adjust all users.
 986         * src/lalr.h (nlookaheads): Remove this orphan declaration.

 988         state.
 989
 990 2001-12-17  Akim Demaille  <akim@epita.fr>
 991
 992         * src/files.h, src/files.c (open_files, close_files): Remove.
 993         * src/main.c (main): Don't open/close files, nor invoke lex_free,
 994         let...
 995         * src/reader.c (reader): Do it.
 996
 997 2001-12-17  Akim Demaille  <akim@epita.fr>
 998
 999         * src/conflicts.c (print_reductions): Formatting changes.
1000
1001 2001-12-17  Akim Demaille  <akim@epita.fr>
1002
1003         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
1004         (flush_reduce): New.
1005         (resolve_sr_conflict): Adjust.
1006
1007 2001-12-17  Akim Demaille  <akim@epita.fr>
1008
1009         * src/output.c (output_obstack): Be static and rename as...
1010         (format_obstack): this, to avoid any confusion with files.c's
1011         output_obstack.
1012         * src/reader.h (muscle_obstack): Move to...
1013         * src/output.h: here, since it's defined in output.c.
1014
1015 2001-12-17  Akim Demaille  <akim@epita.fr>
1016
1017         * src/output.c (action_row, save_column, default_goto)
1018         (sort_actions, matching_state, pack_vector): Better variable
1019         locality.
1020
1021 2001-12-17  Akim Demaille  <akim@epita.fr>
1022

1024
1025 2001-12-17  Akim Demaille  <akim@epita.fr>
1026
1027         * src/files.c (output_files): Free the output_obstack.
1028         * src/main.c (main): Call print and print_graph conditionally.
1029         * src/print.c (print): Work unconditionally.

1034
1035         * src/output.c (actions_output): Fix. When we use %no-lines,
1036         there is one less line per action.
1037
1038 2001-12-16  Marc Autret  <autret_m@epita.fr>
1039
1040         * src/bison.simple: Remove a useless #line directive.
1041         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1042         * src/output.c (get_lines_number): New.
1043         (output_parser): Adjust, now takes care about the lines of a
1044         output muscles.
1045         Fix line numbering.
1046         (actions_output): Computes the number of lines taken by actions.
1047         (output_master_parser): Insert new skeleton which is the name of
1048         the output parser file name.
1049
1050 2001-12-15  Marc Autret  <autret_m@epita.fr>
1051
1052         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
1053
1054 2001-12-15  Marc Autret  <autret_m@epita.fr>
1055
1056         * src/output.c (output_gram): Keep track of the hairy one.
1057
1058 2001-12-15  Akim Demaille  <akim@epita.fr>
1059
1060         Make `make distcheck' work.
1061
1062         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1063         system.h which uses libgettext.h.
1064
1065 2001-12-15  Akim Demaille  <akim@epita.fr>
1066
1067         * src/nullable.c (set_nullable): Useless rules must be skipped,
1068         otherwise, since we range over their symbols, we might look at a
1069         nonterminal which no longer ``exists'', i.e., it is not counted in
1070         `nvars', hence we overflow our arrays.
1071
1072 2001-12-15  Akim Demaille  <akim@epita.fr>
1073
1074         The header can also be produced directly, without any obstack!
1075         Yahoo!
1076
1077         * src/files.c, src/files.h (defines_obstack): Remove.
1078         (compute_header_macro): Global.
1079         (defines_obstack_save): Remove.
1080         * src/reader.c (parse_union_decl): No longer output to
1081         defines_obstack: its content can be found in the `stype' muscle
1082         anyway.
1083         (output_token_translations): Merge into...
1084         (symbols_output): this.

1090
1091 2001-12-15  Akim Demaille  <akim@epita.fr>
1092
1093         * src/reader.c (parse_union_decl): Instead of handling two obstack
1094         simultaneously, use one to define the `stype' muscle, and use the
1095         value of the latter to fill defines_obstack.
1096         (copy_comment): Remove.
1097         (copy_comment2): Work for a single obstack.
1098         Rename as...
1099         (copy_comment): this.

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

1409 2001-12-10  Akim Demaille  <akim@epita.fr>
1410
1411         Bison dumps core on bash.y.
1412         Reported by Pascal Bart.
1413
1414         * src/warshall.c (bitmatrix_print): New.
1415         (TC): Use it.
1416         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1417         j must be the outer loop.
1418         * tests/regression.at (Broken Closure): New.
1419
1420 2001-12-05  Akim Demaille  <akim@epita.fr>
1421
1422         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1423         its argument.
1424         Reported by Peter Hámorský.
1425
1426 2001-12-05  Akim Demaille  <akim@epita.fr>
1427
1428         * src/conflicts.c (err_table): Remove.
1429         (resolve_sr_conflict): Adjust.
1430         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1431         Rename as...
1432         (state_t.reductions, state_t.shifts): this.
1433
1434 2001-12-05  Akim Demaille  <akim@epita.fr>
1435
1436         * src/reduce.c (reduce_grammar_tables): No longer disable the
1437         removal of useless rules via CPP but via `if (0)', so that the
1438         compiler still check the code is valid.
1439         For instance, it should have noticed `rline' no longer exists: use
1440         the `line' member of rule_t.
1441         * src/gram.c (dummy, rline): Remove, unused.
1442
1443 2001-12-05  Akim Demaille  <akim@epita.fr>
1444
1445         * src/output.c (pack_vector): Use assert, not berror.
1446         * src/main.c (berror): Remove, unused.
1447
1448 2001-12-05  Akim Demaille  <akim@epita.fr>
1449
1450         New experimental feature: if --verbose --trace output all the
1451         items of a state, not only its kernel.
1452
1453         * src/print.c (print_core): If `trace_flag', then invoke closure
1454         before outputting the items of the state (print_core is no longer
1455         a correct name them).
1456         (print_results): Invoke new_closure/free_closure if needed.
1457
1458 2001-12-05  Akim Demaille  <akim@epita.fr>
1459
1460         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1461         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1462         (nitemset): for consistency with the rest of the project.
1463
1464 2001-12-05  Akim Demaille  <akim@epita.fr>
1465
1466         * src/closure.c (print_closure): Improve.
1467         (closure): Use it for printing input and output.
1468
1469 2001-12-05  Akim Demaille  <akim@epita.fr>
1470
1471         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1472         indexed by nonterminals.
1473
1474 2001-12-05  Akim Demaille  <akim@epita.fr>
1475
1476         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1477         what it was!).
1478         * src/warshall.h: Remove accidental duplication of the content.
1479
1480 2001-12-05  Akim Demaille  <akim@epita.fr>
1481
1482         * src/closure.c (set_fderives): De-obfuscate.
1483

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

2205         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
2206         now the tests are run in private dirs, therefore AC_CLEANUP and
2207         family can be simplified to 0-ary.
2208         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,

2234         arg_offset.

3592         issues in Bison, it would mean way too much duplicate effort to
3593         import in Bison features implemented in 2.49c since 2.13.
3594         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

3601 2001-01-19  Akim Demaille  <akim@epita.fr>
3602
3603         Get rid of the ad hoc handling of token_buffer in the scanner: use
3604         the obstacks.
3605
3606         * src/lex.c (token_obstack): New.
3607         (init_lex): Initialize it.  No longer call...
3608         (grow_token_buffer): this.  Remove it.
3609         Adjust all the places which used it to use the obstack.
3610
3611 2001-01-19  Akim Demaille  <akim@epita.fr>
3612
3613         * src/lex.h: Rename all the tokens:
3614         s/\bENDFILE\b/tok_eof/g;
3615         s/\bIDENTIFIER\b/tok_identifier/g;
3616         etc.
3617         Let them be enums, not #define, to ease debugging.
3618         Adjust all the code.
3619

3626
3627         Since we now use obstacks, more % directives can be enabled.
3628
3629         * src/lex.c (percent_table): Also accept `%yacc',
3630         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3631         `%debug'.
3632         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3633         instead of returning a token.
3634         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3635         * src/reader.c (read_declarations): Adjust.
3636         * src/files.c (open_files): Don't call `compute_base_names', don't
3637         compute `attrsfile' since they depend upon data which might be
3638         *in* the input file now.
3639         (output_files): Do it here.
3640         * src/output.c (output_headers): Document the fact that this patch
3641         introduces a guaranteed SEGV for semantic parsers.
3642         * doc/bison.texinfo: Document them.
3643         * tests/suite.at: Exercise these %options.
3644
3645 2000-12-20  Akim Demaille  <akim@epita.fr>
3646

3666         FILE * parameters.
3667
3668 2000-12-20  Akim Demaille  <akim@epita.fr>
3669
3670         * src/files.c (open_files): Actually the `.output' file is based
3671         on the short_base_name, not base_name.
3672         * tests/suite.at (Checking output file names): Adjust.
3673
3674 2000-12-20  Akim Demaille  <akim@epita.fr>
3675
3676         * src/bison.s1: Remove, we now use directly...

3700         (stringappend): Be just like strcat but allocate.
3701         (base_names): Eve out from open_files.
3702         Try to simplify the rather hairy computation of base_name and

3705         * tests/suite.at (Checking output file names): New test.

3722
3723 2000-12-19  Akim Demaille  <akim@epita.fr>
3724
3725         Let the handling of the skeleton files be local to the procedures
3726         that use it.
3727
3728         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
3729         longer static.

3743 2000-12-19  Akim Demaille  <akim@epita.fr>
3744
3745         * src/files.c (open_files): Yipee!  We no longer need all the code
3746         looking for `/tmp' since we have no tmp file.
3747
3748 2000-12-19  Akim Demaille  <akim@epita.fr>

3777         * lib/obstack.h: Formatting changes.
3778         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3779         prevents type checking.
3780         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3781         cast the value to (void *): assigning a `foo *' to a `void *'
3782         variable is valid.
3783         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3784         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

3819
3820 2000-11-07  Akim Demaille  <akim@epita.fr>
3821
3822         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
3823         Merge in a single CPP if/else.

3864         * src/main.c (main): Don't use `atexit' to register `done', since
3865         it no longer has to remove tmp files, just call `output_files'
3866         when there are no errors.
3867

3971         When a literal string is used to define two different tokens,
3972         `bison -v' segfaults.
3973         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3974
3975         * tests/regression.m4: New file.
3976         Include the core of the sample provided by Piotr Gackiewicz.
3977         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
3978         properly.

3981
3982         * src/reader.c (parse_expect_decl): Keep `count' within the size
3983         of `buffer'.

3985
3986 2000-10-02  Paul Eggert  <eggert@twinsun.com>
3987
3988         * bison.s1 (yyparse): Assign the default value
3989         unconditionally, to avoid a GCC warning and make the parser a
3990         tad smaller.
3991
3992 2000-10-02  Akim Demaille  <akim@epita.fr>
3993
3994         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
3995         options.
3996
3997 2000-10-02  Akim Demaille  <akim@epita.fr>
3998
3999         * src/derives.c, src/print.c, src/reduce.c: To ease the
4000         translation, move some `\n' out of the translated strings.
4001
4002 2000-10-02  Akim Demaille  <akim@epita.fr>
4003
4004         The location tracking mechanism is precious for parse error
4005         messages.  Nevertheless, it is enabled only when `@n' is used in
4006         the grammar, which is a different issue (you can use it in error
4007         message, but not in the grammar per se).  Therefore, there should
4008         be another means to enable it.
4009
4010         * src/getargs.c (getargs): Support `--locations'.
4011         (usage): Report it.
4012         * src/getargs.h (locationsflag): Export it.
4013         * src/lex.c (percent_table): Support `%locations'.
4014         * src/reader.c (yylsp_needed): Remove this variable, now replaced
4015         with `locationsflag'.
4016         * doc/bison.texinfo: Document `--locations' and `%locations'.
4017         Sort the options.
4018         * tests/calc.m4: Test it.
4019
4020         For regularity of the names, replace each
4021         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4022         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4023         In addition replace each `flag' with `_flag'.
4024
4025 2000-10-02  Akim Demaille  <akim@epita.fr>
4026
4027         Also test parse error messages, including with YYERROR_VERBOSE.
4028
4029         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4030         associative).
4031         Use it to check the computations.
4032         Use it to check `nonassoc' is honored.
4033         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4034         `--yyerror-verbose'.
4035         (_AT_CHECK_CALC): Adjust to this option.
4036         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4037
4038 2000-10-02  Akim Demaille  <akim@epita.fr>
4039
4040         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
4041         the latter demonstrates a flaw in the handling of non debugging
4042         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4043         was used in order to simplify:
4044
4045         #if YYDEBUG
4046         if (yydebug)
4047         {
4048         ...
4049         }
4050         #endif
4051
4052         into
4053
4054         if (yydebug)
4055         {
4056         ...
4057         }
4058
4059         unfortunately this leads to a CPP conflict when
4060         `--name-prefix=foo' is used since it produces `#define yydebug
4061         foodebug'.
4062
4063         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4064         (YYDPRINTF): New macro.
4065         Spread its use.
4066         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4067         the bison options.
4068         Also test `--verbose', `--defines' and `--name-prefix'.
4069
4070 2000-10-02  Akim Demaille  <akim@epita.fr>
4071
4072         Improve the readability of the produced parsers.
4073
4074         * src/bison.s1: Formatting changes.
4075         Improve the comment related to the `$' mark.
4076         (yydefault): Don't fall through to `yyresume': `goto' there.
4077         * src/output.c (output_parser): When the `$' is met, skip the end
4078         of its line.
4079         New variable, `number_of_dollar_signs', to check there's exactly
4080         one `$' in the parser skeleton.
4081
4082 2000-10-02  Akim Demaille  <akim@epita.fr>
4083
4084         * lib/xstrdup.c: New file, from the fileutils.
4085         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4086         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4087         instead of strlen + xmalloc + strcpy.
4088         * src/symtab.c (copys): Remove, use xstrdup instead.
4089
4090 2000-10-02  Akim Demaille  <akim@epita.fr>
4091
4092         * src/gram.h (associativity): New enum type which replaces the
4093         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4094         `right_assoc', `left_assoc' and `non_assoc'.
4095         Adjust all dependencies.
4096         * src/reader.c: Formatting changes.
4097         (LTYPESTR): Don't define it, use it as a literal in
4098         `reader_output_yylsp'.
4099         * src/symtab.h (symbol_class): New enum type which replaces the
4100         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4101         `sunknown', `stoken and `snterm'.
4102
4103 2000-10-02  Akim Demaille  <akim@epita.fr>
4104
4105         * src/getargs.c (fixed_outfiles): Rename as...

4107         Adjust dependencies.
4108
4109 2000-10-02  Akim Demaille  <akim@epita.fr>
4110
4111         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4112         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4113         difficult and introduced a lot of core dump.  It turns out that
4114         Bison used an implementation of `xmalloc' based on `calloc', and
4115         at various places it does depend upon the initialization to 0.  I
4116         have not tried to isolate the pertinent places, and all the former
4117         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4118         someone should address this issue.
4119
4120         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4121         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
4122         files.

4132
4133 2000-10-02  Akim Demaille  <akim@epita.fr>
4134
4135         * src/state.h (nstates, final_state, first_state, first_shift)

4214
4215         * src/output.c (token_actions): Introduce a temporary array,

4218
4219 2000-10-02  Akim Demaille  <akim@epita.fr>
4220
4221         `user_toknums' is output as a `short[]' in `output.c', while it is
4222         defined as a `int[]' in `reader.c'.  For consistency with the
4223         other output tables, `user_toknums' is now defined as a table of
4224         shorts.
4225
4226         * src/reader.c (user_toknums): Be a short table instead of an int
4227         table.

4239         order to get rid of the `static' prototypes.
4240         No longer use `register'.
4241         * src/output.h: New file.
4242         Propagate its inclusion in files explicitly prototyping functions

4266         Don't define PARAMS.
4267         * src/system.h: Define PARAMS.
4268         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
4269         purpose of config.h.  system.h must not try to fix wrong

4432         the file name, not the whole `#line LINE FILE'.
4433
4434 2000-03-17  Akim Demaille  <akim@epita.fr>
4435
4436         On syntax errors, report the token on which we choked.
4437
4438         * src/bison.s1 (yyparse): In the label yyerrlab, when

4458         copy_comment.  Removed now unused `match', `ended',
4459         `cplus_comment'.
4460         (copy_comment, copy_string): Moved, to be visible from
4461         copy_definition.

4464

4487
4488         Change the handling of @s so that they behave exactly like $s.
4489         There is now a pseudo variable @$ (readble and writable), location
4490         of the lhs of the rule (by default ranging from the location of
4491         the first symbol of the rhs, to the location of the last symbol,
4492         or, if the rhs is empty, YYLLOC).
4493
4494         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4495         yyval.
4496         (yyparse): When providing a default semantic action, provide a
4497         default location action.
4498         (after the $): No longer change `*YYLSP', just stack YYLOC the
4499         same way you stack YYVAL.
4500         * src/reader.c (read_declarations): Use warns.
4501         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4502         (copy_action, case '@'): Likewise.
4503         Use a standard error message, to save useless work from
4504         translators.
4505
4506 2000-03-17  Akim Demaille  <akim@epita.fr>
4507

4525
4526         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4527         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4528         One `#if YYDEBUG' remains, since it uses variables which are
4529         defined only if `YYDEBUG != 0'.
4530
4531 2000-03-16  Akim Demaille  <akim@epita.fr>

4557         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

4563         the proper line number and file name.
4564         (DEFS): Propagate the location of bison library files and of the
4565         locale files.
4566         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4567         builddir.
4568         * acinclude.m4: Remove, replaced by the directory m4.
4569         * m4/Makefile.am (EXTRA_DIST): New variable.
4570         * m4/gettext.m4: New file, from the fileutils.

5257         major changes to files.c.
