   1 2005-10-30  Paul Eggert  <eggert@cs.ucla.edu>
   2
   3         * bootstrap (cleanup_gnulib): New function.  Use it to clean up
   4         gnulib when interrupted.  This fixes some race conditions and
   5         works around some portability problems (one noted by Paul
   6         Hilfinger).

  16         the %parse-params.
  17         * data/glr.c (YY_SYMBOL_PRINT, yydestroyGLRState): Adjust.

  26         * configure.ac, Makefile.am: Use build-aux.
  27         * config/prev-version, config/announce-gen, config/Makefile.am:
  28         Move to...
  29         * build-aux/prev-version, build-aux/announce-gen,
  30         * build-aux/Makefile.am: here.
  31
  32 2005-10-14  Akim Demaille  <akim@epita.fr>
  33

  35
  36 2005-10-13  Paul Eggert  <eggert@cs.ucla.edu>
  37
  38         * NEWS: Bison now warns if it finds a stray `$' or `@' in an action.

  40
  41 2005-10-13  Akim Demaille  <akim@epita.fr>
  42
  43         * src/scan-skel.l: Output the base name parts of the parser and
  44         header file names.
  45         * tests/output.at (AT_CHECK_OUTPUT): Support subdirectories, and
  46         additional checks.
  47         Use this to exercise C++ outputs in subdirs.
  48         Reported by Oleg Smolsky.
  49
  50 2005-10-12  Paul Eggert  <eggert@cs.ucla.edu>
  51
  52         * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
  53         __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
  54         Problem reported by John P. Hartmann.
  55         * data/yacc.c (YYMODERN_C): Likewise.  Don't define if the user has
  56         already defined it.
  57
  58 2005-10-12  Akim Demaille  <akim@epita.fr>
  59
  60         * src/parse-gram.y (version_check): Exit 63 to please missing
  61         (stands for "version mismatch).
  62         * tests/input.at, doc/bison.texinfo: Adjust.
  63
  64 2005-10-10  Paul Eggert  <eggert@cs.ucla.edu>
  65
  66         Work around portability problems with Visual Age C compiler
  67         (xlc and xlC_r) reported by John P. Hartmann.
  68         * data/location.cc (initial_column, initial_line): Remove.
  69         All uses replaced by 0 and 1.
  70         * src/scan-gram.l (gram_wrap): Redefine to avoid bug in flex 2.5.31
  71         that xlc complains about.
  72         * src/scan-skel.l (skel_wrap): Likewise.
  73         * data/c.m4 (b4_c_function_def): Look at __STDC_VERSION__ as well
  74         as __STDC__.
  75         * data/yacc.c (YYMODERN_C): New macro, which also looks at
  76         __STDC_VERSION__.  Use it everywhere instead of looking at
  77         __STDC__ and __cplusplus.
  78
  79 2005-10-10  Akim Demaille  <akim@epita.fr>
  80
  81         * examples/calc++/test: Be quiet unless VERBOSE.
  82
  83 2005-10-05  Paul Eggert  <eggert@cs.ucla.edu>
  84
  85         * data/c.m4 (yydestruct, yysymprint):
  86         Use YYUSE instead of casting to void.
  87         * data/glr.c (YYUSE): New macro.
  88         (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
  89         Use it instead of rolling our own.
  90         (YYLLOC_DEFAULT, YYCHK, YYDPRINTF, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
  91         (YYCHK1):
  92         Use /*CONSTCOND*/ to suppress lint warnings.
  93         * data/lalr1.cc (YYLLOC_DEFAULT, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
  94         (YY_STACK_PRINT): Use 'false' not '0'.
  95         (YYUSE): New macro.
  96         (yysymprint_, yydestruct_): Use it instead of rolling our own.
  97         * data/yacc.c (YYUSE): New macro.

 105
 106 2005-10-04  Paul Eggert  <eggert@cs.ucla.edu>
 107
 108         Undo the parts of the unlocked-I/O change that substituted
 109         putc or puts for printf.  This might hurt performance a bit,
 110         but some people prefer the printf style.
 111         * data/c.m4 (yysymprint): Prefer printf to puts and putc.
 112         * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.
 113         All uses replaced by YYFPRINTF and YYDPRINTF.
 114         * data/yacc.c: Likewise.
 115         * lib/bitset.c (bitset_print): Likewise.
 116         * lib/bitsetv.c (bitsetv_dump, debug-bitsetv): Prefer printf to

 121         * src/lalr.c (look_ahead_tokens_print): Likewise.
 122         * src/output.c (escaped_output): Likewise.
 123         (user_actions_output): Break apart two printfs.
 124         * src/parse-gram.y (%printer): Prefer printf to putc and puts.
 125         * src/reduce.c (reduce_print): Likewise.
 126         * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
 127         * src/system.h: Include unlocked-io.h rathe than stdio.h.
 128
 129         * data/glr.c (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
 130         Use assignments rather than casts-to-void to suppress
 131         unused-variable warnings.  This pacifies 'lint'.
 132         * data/lalr1.cc (yysymprint_, yydestruct_): Use a call to suppress
 133         unused-variable warnings.
 134
 135 2005-10-03  Juan Manuel Guerrero  <juan.guerrero@gmx.de>
 136
 137         * Makefile.am: DJGPP specific files added to EXTRA_DIST.
 138
 139 2005-10-02  Paul Eggert  <eggert@cs.ucla.edu>
 140
 141         Use unlocked I/O for a minor performance improvement on hosts like
 142         GNU/Linux and Solaris that support unlocked I/O.  The basic idea
 143         is to use the gnlib unlocked-io module, and to prefer putc and
 144         puts to printf when either will work (since the latter doesn't
 145         come in an unlocked flavor).
 146         * bootstrap (gnulib_modules): Add unlocked-io.
 147         * data/c.m4 (yysymprint): Prefer puts and putc to printf.
 148         * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.
 149         Prefer them to YYFPRINTF and YYDPRINTF if either will do,
 150         and similarly for puts and putc and printf.
 151         * data/yacc.c: Likewise.
 152         * lib/bitset.c (bitset_print): Likewise.
 153         * lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.
 154         * lib/bitsetv.c (bitsetv_dump, debug-bitsetv): Prefer putc and puts
 155         to printf.
 156         * lib/lbitset.c (debug_lbitset): Likewise.
 157         * src/closure.c (print_firsts, print_fderives): Likewise.
 158         * src/gram.c (grammar_dump): Likewise.
 159         * src/lalr.c (look_ahead_tokens_print): Likewise.
 160         * src/output.c (escaped_output): Likewise.
 161         (user_actions_output): Coalesce two printfs.
 162         * src/parse-gram.y (%printer): Prefer putc and puts to printf.
 163         * src/reduce.c (reduce_print): Likewise.
 164         * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
 165         * src/system.h: Include unlocked-io.h rather than stdio.h.
 166
 167         * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
 168         this confuses xgettext.
 169
 170 2005-10-02  Akim Demaille  <akim@epita.fr>
 171
 172         * bootstrap (gnulib_modules): Add strverscmp.
 173         * lib/.cvsignore: Add strverscmp.c, strverscmp.h.

 188             Akim Demaille  <akim@epita.fr>
 189
 190         Make sure -odir/foo.cc creates dir/location.hh etc.
 191         * src/files.h (spec_outfile, parser_file_name, spec_name_prefix)
 192         (spec_file_prefix, spec_verbose_file, spec_graph_file)

 211
 212         * lib/subpipe.c: New function end_of_output_subpipe() added
 213         to allow support for non-posix systems. This is a no-op function
 214         for posix systems.
 215
 216         * lib/subpipe.h: New function end_of_output_subpipe() added
 217         to allow support for non-posix systems. This is a no-op function
 218         for posix systems.
 219
 220         * src/output.c (output_skeleton): Use end_of_output_subpipe() to
 221         handle the lack of pipe/fork functionality on non-posix systems.
 222

 273
 274         Port to SunOS 4.1.4, which lacks strtoul and strerror.

 276         * bootstrap (gnulib_modules): Add strerror, strtoul.
 277         * lib/.cvsignore: Add strerror.c, strtol.c, strtoul.c
 278         * m4/.cvsignore: Add strerror.m4, strtol.m4, strtoul.m4.

 284         (YYERROR_VERBOSE_IF): Remove.
 285         (yyn_, yylen_, yystate_, yynerrs_, yyerrstatus_): Remove as
 286         parser members, replaced by...
 287         (yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
 288         local variables.
 289         (yysyntax_error_): Takes the state number as argument.
 290         (yyreduce_print_): Use the argument yyrule, not the former
 291         attribute yyn_.
 292
 293 2005-09-26  Paul Eggert  <eggert@cs.ucla.edu>
 294
 295         * bootstrap (gnulib_modules): Add verify.
 296         * lib/.cvsignore: Add verify.h.
 297         * src/getargs.c: Use ARGMATCH_VERIFY rather than verify.
 298         * src/system.h (verify): Remove.
 299         Include verify.h instead.
 300         * src/tables.c (tables_generate): Use new API for 'verify'.

 303
 304         * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
 305         local variables whose names begin with 'yy'.

 307         Trivial changes from Joel E. Denny.
 308
 309         * bootstrap (gnulib_modules): Remove alloca.  Bison doesn't need
 310         it itself.
 311         * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
 312         don't use alloca any more.
 313
 314         * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
 315         __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
 316         defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
 317         * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
 318         to match yacc.c, to test more hosts.
 319
 320 2005-09-20  Paul Eggert  <eggert@cs.ucla.edu>
 321
 322         * data/yacc.c (YYSIZE_T): Reindent to make it clearer.  This
 323         doesn't affect behavior.
 324         (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
 325         Solaris, AIX, MSC.
 326         (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H.  All uses changed.
 327         This works a bit better with glibc, if user code has already included
 328         stdlib.h.
 329         * doc/bison.texinfo (Bison Parser): Document that users can't
 330         arbitrarily use malloc and free for other purposes.  Document
 331         that <alloca.h> and <malloc.h> might be included.
 332         (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
 333         user must declare alloca.
 334
 335         * HACKING (release): Forwarn the Translation Project about
 336         stable releses.
 337
 338 2005-09-20  Akim Demaille  <akim@epita.fr>
 339
 340         * data/glr.c: Use b4_token_enums, not b4_token_enums_defines.
 341
 342 2005-09-19  Paul Eggert  <eggert@cs.ucla.edu>
 343
 344         * data/yacc.c (YYSIZE_MAXIMUM): New macro.
 345         (YYSTACK_ALLOC_MAXIMUM): Use it.
 346         (yysyntax_error): New function.
 347         (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
 348         multiple syntax errors are reported, and alloca is being used.
 349         Instead, reallocate buffers twice as big each time, so that
 350         we waste at most half the allocated memory.  Start with a small
 351         (128-byte) buffer that will suffice in most cases anyway.
 352         Use yysyntax_error to do most of the work.
 353
 354         * doc/bison.texinfo (Error Reporting, Table of Symbols):
 355         yynerrs is the number of errors reported, not the number of
 356         errors encountered.
 357
 358         * tests/glr-regression.at (Duplicated user destructor for lookahead):
 359         Mark it as expected to fail.
 360         Cast result of malloc; problem reported by twlevo@xs4all.nl.
 361         * tests/actions.at, tests/calc.at, tests/glr-regression.at:
 362         Don't start user-code symbols with "yy", to avoid name space problems.
 363
 364 2005-09-19  Akim Demaille  <akim@epita.fr>
 365
 366         Remove the traits, failed experiment.
 367         It never proved useful, and anyway because of the current
 368         definition, it was not possible to have several specialization of
 369         this traits, making it useless.
 370         * data/lalr1.cc (yy:traits): Remove.
 371         Inline its definitions in the parser class.
 372
 373 2005-09-19  Akim Demaille  <akim@epita.fr>
 374
 375         * tests/atlocal.in (LIBS): Pass INTLLIBS to address failures on at
 376         least Mac OSX with a /usr/local install of gettext.
 377
 378 2005-09-19  Akim Demaille  <akim@epita.fr>
 379
 380         * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
 381         and yytoken for similarity with the other skeletons.
 382
 383 2005-09-19  Akim Demaille  <akim@epita.fr>
 384
 385         * NEWS, configure.ac: Bump to 2.1a.
 386
 387 2005-09-16  Paul Eggert  <eggert@cs.ucla.edu>
 388
 389         * NEWS: Version 2.1.
 390
 391         * NEWS: Remove notice of yytname change, since it was never in an
 392         official release.
 393         * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
 394         diagnostic.
 395         * src/output.c (prepare): Likewise.
 396         * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
 397         (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
 398         is not defined.  This is an awful hack, but it's enough for now.
 399         All callers changed.
 400         * tests/glr-regression-at (make_value): Args are const pointers now,
 401         to avoid GCC warning.
 402         (Duplicated user destructor for lookahead): New test.  Currently
 403         skipped.  It fails on my host but I'm not sure it'll always fail.
 404
 405 2005-09-16  Akim Demaille  <akim@epita.fr>
 406
 407         * src/symtab.h (struct symbol): Declare the printer and destructor
 408         as const, to avoid accidental calls to free.
 409         (symbol_destructor_set, symbol_printer_set): Adjust.
 410         * src/symtab.c: Adjust.
 411
 412 2005-09-16  Akim Demaille  <akim@epita.fr>
 413
 414         * data/c.m4 (b4_token_enums): New.
 415         (b4_token_defines): Rename as...
 416         (b4_token_enums_defines): this.
 417         (b4_token_defines): New, output only the #defines.
 418         * data/yacc.c, data/glr.c: Adjust.
 419         * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
 420         * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
 421         as default values.
 422
 423 2005-09-16  Akim Demaille  <akim@epita.fr>
 424
 425         * data/lalr1.cc (yylex_): Remove, inline its code.
 426         (yyreport_syntax_error_): Remove, replaced by...
 427         (yysyntax_error_): this which returns a string and leaves to the
 428         caller the call to the users' error function.
 429         (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
 430         Move from members of the parser object...
 431         (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
 432         to local variables of the parse function.
 433
 434 2005-09-16  Akim Demaille  <akim@epita.fr>
 435
 436         * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
 437         since it's in Bison's name space.
 438
 439 2005-09-15  Paul Eggert  <eggert@cs.ucla.edu>
 440
 441         * data/glr.c (yyresolveValue): Add default case to pacify
 442         gcc -Wswitch-default.  Problem reported by twlevo@xs4all.nl.
 443
 444         * NEWS: Document when yyparse started to return 2.
 445         * doc/bison.texinfo (Parser Function): Document when yyparse
 446         returns 2.
 447
 448         * data/lalr1.cc: Revert part of previous change, as it's incompatible.
 449         (b4_filename_type): Renamed back from b4_file_name_type.  All uses
 450         changed.
 451         (class position): file_name -> filename (reverting).  All uses changed.
 452
 453 2005-09-14  Paul Eggert  <eggert@cs.ucla.edu>
 454
 455         * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
 456         do anything if $@ exists.  This reverts part of the 2005-07-07
 457         patch.
 458
 459 2005-09-11  Paul Eggert  <eggert@cs.ucla.edu>
 460
 461         * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
 462         contains obsolete information and isn't worth distributing as a
 463         separate file anyway.
 464         * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
 465         (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
 466         All uses of jmp_buf, setjmp, longjmp changed to use these instead.
 467         (yyparse): Abort if user code uses longjmp to throw an unexpected
 468         value.
 469
 470 2005-09-09  Paul Eggert  <eggert@cs.ucla.edu>
 471
 472         * data/c.m4 (b4_identification): Define YYBISON_VERSION.
 473         Suggested by twlevo@xs4all.nl.
 474
 475         * data/glr.c (YYCHK1): Do not assume YYE is in range.
 476         This avoids a diagnostic from gcc -Wswitch-enum.
 477         Problem reported by twlevo@xs4all.nl.
 478
 479         * doc/bison.texinfo: Don't use "filename", as per GNU coding
 480         standards.  Use "file name" or "file" or "name", depending on
 481         the context.
 482         (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
 483         not to hack/foo.tab.c.
 484         (Calc++ Top Level): 2nd arg of main is not const.
 485         * data/glr.c: b4_filename -> b4_file_name.
 486         * data/lalr1.cc: Likewise.  Also, b4_filename_type -> b4_file_name_type.
 487         All uses changed.
 488         (class position): filename -> file_name.  All uses changed.
 489         * data/yacc.c: b4_filename -> b4_file_name.
 490         * lib/bitset.h: filename -> file_name in local vars.
 491         * lib/bitset_stats.c: Likewise.
 492         * src/files.c: Likewise.
 493         * src/scan-skel.l ("@output ".*\n): Likewise.
 494         * src/files.c (file_name_split): Renamed from filename_split.
 495         * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.
 496
 497 2005-09-08  Paul Eggert  <eggert@cs.ucla.edu>
 498
 499         * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
 500         to accommodate latest gnulib.
 501
 502         * tests/glr-regression.at (Duplicate representation of merged trees):
 503         Add casts to pacify g++.  Problem reported by twlevo@xs4all.nl.
 504
 505         * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
 506         needed.
 507
 508 2005-08-26  Paul Eggert  <eggert@cs.ucla.edu>
 509
 510         * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
 511         All uses changed.  Invoke user destructor after an error during a
 512         split parse (trivial change from Joel E. Denny).
 513
 514         * tests/glr-regression.at
 515         (User destructor after an error during a split parse):  New test case.
 516         Problem reported by Joel E. Denny in:
 517         http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
 518
 519 2005-08-25  Paul Eggert  <eggert@cs.ucla.edu>
 520
 521         * README-cvs: Give URLs for recommended tools.
 522         Mention Gzip version problem, and bootstrapping issues.
 523         Remove troubleshooting section, as it's somewhat obsolete.
 524
 525         * bootstrap (no_cache): New var, to accommodate different wget
 526         variants.  Use it instead of '-C off'.  Problem reported by
 527         twlevo@xs4all.nl.
 528
 529         * data/glr.c (yydestroyStackItem): New function.
 530         (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
 531         debugging information.  Problem reported by Joel E. Denny.
 532
 533 2005-08-25  Akim Demaille  <akim@epita.fr>
 534
 535         * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
 536
 537 2005-08-24  Paul Eggert  <eggert@cs.ucla.edu>
 538
 539         * data/glr.c (yyrecoverSyntaxError, yyreturn):
 540         Don't invoke destructor on unresolved entries.
 541         * tests/glr-regression.at
 542         (User destructor for unresolved GLR semantic value): New test case.
 543         Problem reported by Joel E. Denny in:
 544         http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
 545
 546 2005-08-21  Paul Eggert  <eggert@cs.ucla.edu>
 547
 548         * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
 549         Add strnlen.c.
 550         * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
 551         lib-prefix.m4, po.m4.
 552
 553         * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
 554         in yydestruct diagnostic, since it might not be an error.
 555         Problem reported by Joel Denny near end of
 556         <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
 557         * data/lalr1.cc (yyerturn): Likewise.
 558         * data/yacc.c (yyreturn): Likewise.
 559         * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
 560
 561         * src/files.c: Remove obsolete FIXME comment.
 562
 563         * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
 564         with the other templates, and to fix bogus run-on messages such
 565         as the one reported at the end of
 566         <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
 567         All callers changed to avoid the newline.
 568         (yyprocessOneStack): Output two lines rather than one, to accommodate
 569         the above change.  This changes the debug output format slightly.
 570
 571         * data/glr.c (yyresolveValue): Fix redundant parse tree problem
 572         reported by Joel E. Denny in
 573         <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
 574         (trivial change).
 575         * tests/glr-regression.at (Duplicate representation of merged trees):
 576         New test, from Joel E. Denny in:
 577         <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
 578         * THANKS: Add Joel E. Denny.
 579
 580         * configure.ac (AC_INIT): Bump to 2.0c.
 581
 582 2005-07-24  Paul Eggert  <eggert@cs.ucla.edu>
 583
 584         * NEWS: Version 2.0b.
 585
 586         * Makefile.am (SUBDIRS): Put examples before tests, so that
 587         "make check" doesn't finish with "All 1 tests passed".
 588
 589         * tests/regression.at (Token definitions): Don't rely on
 590         AT_PARSER_CHECK for data that contains backslashes.  It currently
 591         uses 'echo', and 'echo' isn't portable if its argument contains
 592         backslashes.  Problem found on OpenBSD 3.4.  Also, do not assume
 593         that the byte '\0xff' is not printable in the C locale; it is,
 594         under OpenBSD 3.4 (!).  Luckily, '\0x80' through '\0x9e' are
 595         not printable, so use '\0x81' to test.
 596
 597         * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
 598         version of GCC, since the macro is used with non-GCC compilers.
 599
 600         Fix core dump reported by Pablo De Napoli in
 601         <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
 602         * tests/regression.at (Invalid inputs with {}): New test.
 603         * src/parse-gram.y (token_name): Translate type before using
 604         it as an index.
 605
 606         * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
 607         the user's name space.  All uses changed to __attribute__
 608         ((__unused__)).
 609         (yyFail, yyMemoryExhausted, yyreportAmbiguity):
 610         Add __attribute__ ((__noreturn__)).
 611
 612         * etc/clcommit: Remove.  We weren't using it, and it failed
 613         "make maintainer-distcheck".
 614         * Makefile.maint: Merge from coreutils.
 615         (CVS_LIST, CVS_LIST_EXCEPT): New macros.
 616         (syntax-check-rules): Change list of rules as described below.
 617         (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
 618         (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
 619         (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
 620         (sc_trailing_space): New rules.
 621         (sc_xalloc_h_in_src): Remove.
 622         (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
 623         (sc_space_tab, sc_error_exit_success, sc_changelog):
 624         (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
 625         (makefile-check, po-check, author_mark_check):
 626         (makefile_path_separator_check, copyright-check):
 627         Use grep -n, to make it easier to find violations.
 628         Use CVS_LIST and CVS_LIST_EXCEPT.
 629         (header_regexp, h_re): Remove.
 630         (dd_c): New macro.
 631         (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
 632         (my-distcheck): Use more-modern GCC flags.
 633         (signatures, %.asc): Remove.
 634         (rel-files, announcement): Remove signatures.
 635         Restore old updating code, even though we don't use it, so
 636         that we're the same as coreutils.
 637         (alpha, beta, major): Depend on news-date-check.
 638         Make the upload commands.
 639
 640         * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
 641         * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
 642         * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
 643         * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
 644         * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
 645         * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
 646         * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
 647         * tests/sets.at: Likewise.
 648
 649         * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
 650         we comment out the Autoconf version number.
 651         * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
 652         it's error-prone and "make maintainer-distcheck" rejects it.
 653
 654         * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
 655         Indent calls to "error" to pacify "make maintainer-distcheck",
 656         when the calls are not intended to be translated.
 657         * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
 658
 659         * src/Makefile.am (DEFS): Use +=, to pacify
 660         "make maintainer-distcheck".
 661         (bison_SOURCES): Add scan-skel.h.
 662         (sc_tight_scope): New rule, from coreutils.
 663
 664         * src/files.c (src_extension, header_extension):
 665         Now static, not extern.
 666         * src/getargs.c (short_options): Likewise.
 667         * src/muscle_tab.c (muscle_table): Likewise.
 668         * src/parse-gram.y (current_class, current_type, current_prec):
 669         Likewise.
 670         * src/reader.c (grammar_end, previous_rule_end): Likewise.
 671         * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
 672         * src/main.c (main): Cast bindtextdomain and textdomain calls to
 673         void, to avoid warning when NLS is disabled.
 674         * src/output.c: Include scan-skel.h.
 675         (scan_skel): Remove decl, since scan-skel.h does this.
 676         (output_skeleton):
 677         Indent calls to "error" to pacify "make maintainer-distcheck".
 678         * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
 679         * src/reader.h (gram_end, gram_lineno): New decls to pacify
 680         "make maintainer-distcheck".
 681         * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
 682         (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
 683         (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
 684         (skel_lex_destroy, scan_skel): Move these decls to...
 685         * src/scan-skel.h: New file.
 686         * src/uniqstr.c (uniqstr_assert):
 687         Indent calls to "error" to pacify "make maintainer-distcheck".
 688
 689         * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
 690         not @VAR@.
 691
 692         * tests/torture.at: Revamp to avoid misuse of atoi that
 693         "make maintainer-distcheck" complained about.
 694
 695         * examples/extexi (message): Don't print a message more than once,
 696         and omit line-number decoration that makes Emacs compile think
 697         that informative messages are worth worrying about.
 698
 699 2005-07-22  Paul Eggert  <eggert@cs.ucla.edu>
 700
 701         * configure.ac: Update version number.
 702
 703         * Makefile.am (SUBDIRS): Add examples; somehow this got removed
 704         accidentally.
 705         * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
 706         autogenerated by the maintainer.
 707         * examples/calc++/.cvsignore: Add *.yy.
 708
 709         * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
 710         * lib/bitset_stats.c (bitset_stats_init): Likewise.
 711         * lib/bitsetv.c (bitsetv_alloc): Likewise.
 712
 713         * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
 714
 715         * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
 716         from maintainer-distcheck about casting the argument of 'free'.
 717
 718         * NEWS: Mention recent yytname changes.
 719         * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
 720
 721         * bootstrap: For translations that have not yet been upgraded to
 722         the new runtime-po domain, prime the pump by extracting the
 723         relevant strings from the obsolete translations.  This code can be
 724         removed once the bison-runtime domain has been translated by each
 725         team.
 726
 727         * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
 728         now that token names are already quoted.
 729
 730         Fix problem reported by Anthony Heading.
 731         * data/glr.c (YYTOKEN_TABLE): New macro.
 732         (yytname): Define if YYTOKEN_TABLE.
 733         * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
 734         * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
 735         (YYERROR_VERBOSE): Define the same way the other skeletons do.
 736         * src/output.c (prepare_symbols): Output token_table_flag.
 737
 738 2005-07-21  Paul Eggert  <eggert@cs.ucla.edu>
 739
 740         * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
 741         again if the first call fails.
 742
 743         * data/glr.c (yytnamerr): New function.
 744         (yyreportSyntaxError): Use it to dequote most string literals.
 745         * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
 746         with other skeletons.  All uses changed.
 747         (yytnameerr_): New function.
 748         (yyreport_syntax_error): Use it to dequote most string literals.
 749         * data/yacc.c (yytnamerr): New function.
 750         (yyerrlab): Use it to decode most string literals.
 751         * doc/bison.texinfo (Decl Summary, Calling Convention):
 752         Clarify quoting convention of yytname.
 753         * src/output.c (prepare_symbols): Quote all names.  This undoes
 754         the 2005-04-17 change, which is now accomplished (mostly) via
 755         changes in the parsers as described above.
 756         * tests/regression.at (Token definitions, Web2c Actions):
 757         Undo most 2005-04-17 change here, too.
 758
 759 2005-07-20  Paul Eggert  <eggert@cs.ucla.edu>
 760
 761         Fix more problems reported by twlevo@xs4all.nl.
 762         * tests/cxx-type.at: Don't pipe output of ./types through sed to
 763         remove trailing spaces.  This loses the exit status of ./types,
 764         and isn't needed since ./types shouldn't be emitting trailing
 765         spaces.
 766         * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
 767         as the stack isn't valid in that case.
 768
 769         * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
 770         (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
 771         (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
 772         Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
 773         is used.
 774         * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
 775         (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
 776         (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
 777         Likewise.
 778
 779         * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
 780         overly-picky compilers that reject 'char *foo = "bar";'.
 781
 782         * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
 783         to FILE * parameter, not to stderr.  This fixes a typo introduced
 784         in the 2005-07-12 change.
 785
 786         * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
 787         warnings from GCC 4.
 788
 789         * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
 790         (yyglrShiftDefer, yysplitStack):
 791         Remove unused parameters b4_pure_formals.  All uses changed.
 792         (yyglrShift): Remove unused parameters b4_user_formals.
 793         All uses changed.
 794         (yyglrReduce): Removed unused parameter yylocp.  All uses changed.
 795
 796 2005-07-18  Paul Eggert  <eggert@cs.ucla.edu>
 797
 798         Destructor cleanups and regularization among the three skeletons.
 799         * NEWS: Document the behavior changes.
 800         * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
 801         stack before failing, as the cleanup code will do it for us now.
 802         * data/lalr1.cc (yyerrlab): Likewise.
 803         * data/glr.c (yyparse): Pop everything off the stack before
 804         freeing it, so that destructors get called properly.
 805         * data/lalr1.cc (yyreturn): Likewise.
 806         * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
 807         This is more consistent.
 808         * doc/bison.texinfo (Destructor Decl): Mention more reasons
 809         why destructors might be called.  1.875 -> 2.1.
 810         (Destructor Decl, Decl Summary, Table of Symbols):
 811         Some English-language cleanups for %destructor.
 812         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
 813         Add output line for destructor of start symbol.
 814         * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
 815         because of that same extra output line.
 816
 817         * NEWS: Document minor wording changes in diagnostics of
 818         Bison-generated parsers.
 819         * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
 820         Remove unused formals.  All uses changed.
 821         (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
 822         (yyparse): Rename yyoverflowlab to yyexhaustedlab.
 823         * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
 824         Rename yyoverflowab to yyexhaustedlab.
 825         When memory exhaustion occurs during syntax-error reporting,
 826         report it separately rather than in a single diagnostic; this
 827         eases translation.
 828         * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
 829         (Memory Exhausted): Renamed from Parser Stack Overflow.
 830         Revamp wording slightly to prefer "memory exhaustion".
 831         * tests/actions.at: "parser stack overflow" -> "memory exhausted".
 832
 833         * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
 834
 835         Add i18n support to the GLR skeleton.  Partially fix the C++
 836         skeleton; a C++ expert needs to finish this.  Remove debugging
 837         msgids; there's little point to having them translated, since they
 838         can be understood only by someone who can read the
 839         (English-language) source code.
 840
 841         Generate runtime-po/bison-runtime.pot automatically, so that we
 842         don't have to worry about garbage getting in that file.  We'll
 843         make sure after the next official release that old msgids don't
 844         get lost.  See
 845         <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
 846
 847         * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
 848         Now auto-generated.
 849         * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
 850         Fix typos in explanations of the runtime file.
 851         * bootstrap: Change gettext keyword from YYI18N to YY_.
 852         Use standard Makefile.in.in in runtime-po, since we'll arrange
 853         for backward-compatible bison-runtime.po files in a different way.
 854         * data/glr.c (YY_): New macro, from yacc.c.
 855         (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
 856         Translate messages intended for users.
 857         (yyreportSyntaxError): Change "virtual memory" to "memory" to match
 858         the wording in the other skeletons.  We don't know that the memory
 859         is virtual.
 860         * data/lalr1.cc (YY_): Renamed from _.  All uses changed.
 861         Use same method that yacc.c uses.
 862         Don't translate debugging messages.
 863         (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
 864         it doesn't work (yet), and requires C++ expertise to fix.
 865         * data/yacc.c (YY_): Renamed from YY18N.  All uses changed.
 866         Move defn to a more logical place, to be consistent with other
 867         skeletons.
 868         Don't translate debugging messages.
 869         Don't assume line numbers fit in unsigned int; use unsigned long fmts.
 870         * doc/bison.texinfo: Mention <libintl.h>.  Change glibc cross reference
 871         to gettext cross reference.  Add indexing terms.  Mention YYENABLE_NLS.
 872         * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
 873
 874         Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
 875         * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
 876         void, not int.
 877         * tests/glr-regression.at (Badly Collapsed GLR States):
 878         Likewise.
 879         (Improper handling of embedded actions and dollar(-N) in GLR parsers):
 880         yylex should return 0 at EOF rather than aborting.
 881
 882         Improve tests for stack overflow in GLR parser.
 883         Problem reported by twlevo@xs4all.nl.
 884         * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
 885         All uses removed.
 886         (yyStackOverflow): Just longjmp, but with value 2 so that caller
 887         can handle the problem.
 888         (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
 889         (yyparse): New local variable yyresult to record the result.
 890         Use result of setjmp to set it, rather than storing itinto
 891         struct.
 892         (yyDone): Remove label.
 893         (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
 894         to mimic yacc.c.  Do not discard lookahead if it's EOF (possible
 895         if YYABORT is used).
 896         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
 897         yyparse status; put status > 1 into diagnostic.
 898         Check that status==2 works.
 899         * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
 900         Use exit status 3 for failure to open (which shouldn't happen).
 901
 902 2005-07-17  Paul Eggert  <eggert@cs.ucla.edu>
 903
 904         * tests/conflicts.at (%nonassoc and eof):  Don't exit with status
 905         1 on syntax error; just let yyparse do its thing.
 906         * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
 907         * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
 908         (Exploding the Stack Size with Alloca):
 909         (Exploding the Stack Size with Malloc):
 910         Expect exit status 2, not 1, since the parser is supposed to blow
 911         its stack.  Problem reported by twlevo@xs4all.nl.
 912
 913         * data/glr.c (yyparse): Don't assume that the initial calls
 914         to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
 915         Print a stack-overflow message and fail instead.
 916         Initialize the line-number information before creating the stack,
 917         so that the stack-overflow message can report line zero safely.
 918
 919 2005-07-14  Paul Eggert  <eggert@cs.ucla.edu>
 920
 921         Fix problems reported by twlevo@xs4all.nl.
 922         * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
 923         (yyuserMerge): Provide a default case if b4_mergers is empty.
 924         * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
 925         * tests/glr-regression.at
 926         (Improper handling of embedded actions and dollar(-N) in GLR parsers):
 927         Add casts to pacify C++ compilers.
 928         * tests/glr-regression.at (Improper merging of GLR delayed action
 929         sets): Declare yylex before using it.
 930         * tests/Makefile.am (maintainer-check-g++): Fix a stray
 931         $(GXX) that escaped the renaming of GXX to CXX.  Remove bogus
 932         test for valgrind; valgrind is independent of g++.
 933         (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
 934         for compatibility with POSIX 1003.1-2001 (if running coreutils).
 935         * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
 936         Use a destructor, so that we can expand the stack.  Change
 937         YYSTYPE to char * so that we can free it.  Cast result of malloc.
 938
 939 2005-07-13  Paul Hilfinger  <hilfingr@CS.Berkeley.EDU>
 940
 941         * data/glr.c (yyuserAction): Fix uninitialized variable that caused
 942         a valgrind failure.  Problem reported by twlevo@xs4all.nl.
 943
 944 2005-07-13  Paul Eggert  <eggert@cs.ucla.edu>
 945
 946         * PACKAGING: New file, suggested by Bruno Haible and taken from
 947         similar wording in gettext's PACKAGING file.
 948         * NEWS: Mention PACKAGING.
 949         * Makefile.am (EXTRA_DIST): Add PACKAGING.
 950
 951 2005-07-12  Paul Eggert  <eggert@cs.ucla.edu>
 952
 953         * NEWS: Document recent i18n improvements.
 954         * bootstrap: Get runtime translations into runtime-po.
 955         Create runtime-po files automatically, if possible.
 956         * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
 957         * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
 958         does not infringe on the user's name space.
 959         (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
 960         * doc/bison.texinfo (Internationalization): Revamp the English
 961         and Texinfo syntax a bit, to try to make it clearer.
 962         (Bison Options, Option Cross Key): Mention --print-localedir.
 963         * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
 964         YYENABLE_NLS.  Quote a bit more.
 965         * runtime-po/.cvsignore: New file.
 966         * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
 967         * runtime-po/Rules-quot: Remove; now created by bootstrap.
 968         * runtime-po/quot.sed: Likewise.
 969         * runtime-po/boldquot.sed: Likewise.
 970         * runtime-po/en@quot.header: Likewise.
 971         * runtime-po/en@boldquot.header: Likewise.
 972         * runtime-po/insert-header.sin: Likewise.
 973         * runtime-po/remove-potcdate.sin: Likewise.
 974         * runtime-po/Makevars: Likewise.
 975         * runtime-po/LINGUAS: Likewise.
 976         * runtime-po/de.po: Likewise; we will rely on the translation project
 977         to maintain this, so "bootstrap" should get it.
 978         * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
 979         its value.
 980         * src/main.c (main): Bind the bison-runtime domain, too.

 984         * data/yacc.c: Include <libintl.h> when NLS is enabled.
 985         (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
 986         * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
 987         * runtime-po: New directory.
 988         * runtime-po/Makefile.in.in: New file, copied from po/, with modified
 989         $(DOMAIN).pot-update rule, so that old messages are never dropped.
 990         * runtime-po/Rules-quot: New file, copied from po/.
 991         * runtime-po/quot.sed: Likewise.
 992         * runtime-po/boldquot.sed: Likewise.
 993         * runtime-po/en@quot.header: Likewise.
 994         * runtime-po/en@boldquot.header: Likewise.
 995         * runtime-po/insert-header.sin: Likewise.
 996         * runtime-po/remove-potcdate.sin: Likewise.
 997         * runtime-po/Makevars: New file.
 998         * runtime-po/POTFILES.in: New file.
 999         * runtime-po/LINGUAS: New file.
1000         * runtime-po/bison-runtime.pot: New file.
1001         * runtime-po/de.po: New file.
1002         * m4/bison.m4: New file.
1003         * Makefile.am (SUBDIRS): Add runtime-po.
1004         (aclocaldir, aclocal_DATA): New variables.
1005         * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
1006         Define aclocaldir.
1007         * src/getargs.c (usage): Document --print-localedir option.
1008         (PRINT_LOCALEDIR_OPTION): New enum item.
1009         (long_options): Add --print-localedir option.
1010         (getargs): Handle --print-localedir option.
1011         * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
1012         (Internationalization): New section.
1013
1014 2005-07-12  Akim Demaille  <akim@epita.fr>
1015
1016         * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
1017         for consistency with the rest of the code.
1018         * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
1019         Add separators.
1020
1021 2005-07-12  Akim Demaille  <akim@epita.fr>
1022
1023         * src/parse-gram.y: Use %printer instead of YYPRINT.
1024
1025 2005-07-12  Akim Demaille  <akim@epita.fr>
1026
1027         * src/symtab.h, src/symtab.c (symbol_print): New.
1028         * src/symlist.h, src/symlist.c (symbol_list_print): New.
1029         * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
1030
1031 2005-07-12  Akim Demaille  <akim@epita.fr>
1032
1033         * data/glr.c (b4_syncline): Fix (swap) the definitions of
1034         b4_at_dollar and b4_dollar_dollar.
1035
1036 2005-07-11  Paul Eggert  <eggert@cs.ucla.edu>
1037
1038         * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
1039         and Pennello's paper.
1040
1041 2005-07-09  Paul Eggert  <eggert@cs.ucla.edu>
1042
1043         * data/yacc.c (yyparse): Undo previous patch.  Instead,
1044         set yylsp[0] and yyvsp[0] only if the initial action
1045         sets yylloc and yylval, respectively.
1046
1047         * data/yacc.c (yyparse): In the initial action, set
1048         yylsp[0] and yyvsp[0] rather than yylloc and yylval.
1049         This avoids the use of undefined variables if the initial
1050         action does not set yylloc and/or yylval.
1051
1052 2005-07-07  Paul Eggert  <eggert@cs.ucla.edu>
1053
1054         * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
1055         * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
1056         Remove from CVS.  These files are automatically generated.
1057         * examples/extexi: Clarify that this file is now part of Bison,
1058         not GNU M4, and that it works with any POSIX-compatible Awk.
1059         * examples/calc++/Makefile.am (run_extexi): Remove; not used.
1060         ($(calc_extracted)): Renamed from $(calc_sources_extracted),
1061         so that we also get calc++-parser.yy.  Geneate it.
1062         Use $(AWK), not gawk, since any conforming Awk will do.
1063         Put comment before action, since older 'make' can't handle comment
1064         in action.
1065         $(BUILT_SOURCES): List all built sources, not just some of them.
1066         $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
1067         $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
1068         $($(calc_sources_generated)): Remove unnecessary test for existence
1069         of target.  (This had a shell syntax error anyway; a stray "x".)
1070         (calc_extracted): List $(srcdir)/calc++-parser.yy, not
1071         calc++-parser.yy.
1072         * examples/.cvsignore, examples/calc++/.cvsignore: New files.
1073
1074         * bootstrap (gnulib_modules): Add gettext, now that it's no longer
1075         implied by the other modules.
1076
1077 2005-07-06  Akim Demaille  <akim@epita.fr>
1078
1079         Bind examples/calc++ to the package.
1080         * examples/calc++/Makefile: Remove, replaced by...
1081         * examples/calc++/Makefile.am: ... this new file.
1082         * examples/calc++/test: Remove input.
1083         * examples/calc++/compile: Remove.
1084         * examples/Makefile.am: New.
1085         * configure.ac, Makefile.am: Adjust.
1086         * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
1087
1088 2005-07-05  Paul Eggert  <eggert@cs.ucla.edu>
1089
1090         * data/glr.c (yyFail): Drastically simplify; since the format argument
1091         never had any % directives, we can simply pass it to yyerror.
1092         (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
1093         be modified later, as that is the usual style in glr.c.
1094         Problems reported by Paul Hilfinger.
1095
1096         Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
1097         and size overflow errors.
1098         * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
1099         in case the user prolog sets feature-test macros like _GNU_SOURCE.
1100         (YYSIZEMAX): New macro.
1101         (yystpcpy): New function, taken from yacc.c.
1102         (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
1103         (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
1104         so that we don't have to maintain their signatures.
1105         (yyFail): Check for buffer overflow, by using vsnprintf rather
1106         than vsprintf.  Allocate a bigger buffer if possible.
1107         Report an error if buffer allocation fails.
1108         (yyStackOverflow): New function.
1109         (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
1110         the initialization was successful.  It might fail if storage was
1111         exhausted.
1112         (yyexpandGLRStack): Add more checks for storage allocation failure.
1113         Use yyStackOverflow to report failures.
1114         (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
1115         (yysplitStack, yyprocessOneStack, yyparse, yypstack):
1116         Don't assume stack number fits in int.
1117         (yysplitStack): Check for storage allocation failure.
1118         (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
1119         can print diagnostics on storage allocation failure.  All callers
1120         changed.
1121         (yyresolveValue): Use yybool for boolean.
1122         (yyreportSyntaxError): Check for size-calculation overflow.
1123         This code is taken from yacc.c.
1124         (yyparse): Check for storage allocation errors when allocating
1125         the initial stack.
1126
1127 2005-07-05  Akim Demaille  <akim@epita.fr>
1128
1129         Extract calc++ from the documentation.
1130         * doc/bison.texinfo (Calc++): Add the extraction marks.
1131         * examples/extexi: New, from the aborted GNU Programming 2E.
1132         Separate the different paragraph of a file with empty lines.
1133         * examples/Makefile: Use it to extract the whole calc++ example.
1134
1135 2005-06-24  Akim Demaille  <akim@epita.fr>
1136
1137         * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
1138         class typedefs.
1139
1140 2005-06-22  Akim Demaille  <akim@epita.fr>
1141
1142         * doc/bison.texinfo (C++ Language Interface): First stab.
1143         (C++ Parsers): Remove.
1144
1145 2005-06-22  Akim Demaille  <akim@epita.fr>
1146
1147         * data/lalr1.cc (yylex_): Honor %lex-param.
1148
1149 2005-06-22  Akim Demaille  <akim@epita.fr>
1150
1151         Start a set of simple examples.
1152         * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
1153         * examples/calc++/calc++-driver.hh,
1154         * examples/calc++/calc++-parser.yy,
1155         * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
1156         * examples/calc++/compile, examples/calc++/test: New.
1157
1158 2005-06-09  Paul Eggert  <eggert@cs.ucla.edu>
1159
1160         * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
1161         extern "C" {}.  This fixes a problem reported by Paul Hilfinger,
1162         which stems from the 2005-05-27 patch.
1163
1164 2005-06-06  Paul Hilfinger  <hilfingr@tully.CS.Berkeley.EDU>
1165
1166         * data/glr.c: Modify treatment of unused parameters to permit use
1167         of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
1168
1169 2005-05-30  Paul Eggert  <eggert@cs.ucla.edu>
1170
1171         Fix infringement on user name space reported by Janos Zoltan Szabo.
1172         * data/yacc.c (yyparse): strlen -> yystrlen.
1173
1174 2005-05-30  Akim Demaille  <akim@epita.fr>
1175
1176         * data/lalr1.cc (_): New.
1177         Translate the various messages.
1178
1179 2005-05-27  Paul Eggert  <eggert@cs.ucla.edu>
1180
1181         Fix infringement on user name space reported by Bruno Haible.
1182         * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
1183         Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
1184         the user's name space.
1185         (alloca): Include <stdlib.h> to get it, if it's not built in.
1186         (YYMALLOC, YYFREE): Define only if needed.
1187         (malloc, free): Declare, but only if needed, as this infringes on
1188         the user name space.
1189
1190 2005-05-25  Paul Eggert  <eggert@cs.ucla.edu>
1191
1192         Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
1193         * lib/bitset.c (bitset_print): Don't assume size_t can be printed
1194         with %d format.
1195         * lib/ebitset.c (min, max): Undef before defining.
1196         * lib/vbitset.c (min, max): Likewise.
1197         * lib/subpipe.c (create_subpipe): Save local variables in case
1198         vfork clobbers them.
1199
1200 2005-05-24  Bruno Haible  <bruno@clisp.org>
1201
1202         * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
1203         error message syntax used by gcc-4.0.
1204
1205 2005-05-23  Paul Eggert  <eggert@cs.ucla.edu>
1206
1207         * README: Mention m4 1.4.3.  Remove obsolete advice about
1208         Sun Forte Developer 6 update 2, VMS, and MS-DOS.
1209
1210         * bootstrap: Remove workaround for problem I encountered with
1211         gettext 0.14.1; it seems to be fixed now.
1212
1213 2005-05-22  Paul Eggert  <eggert@cs.ucla.edu>
1214
1215         * NEWS: Version 2.0a.
1216
1217         * src/files.c: Include "stdio-safer.h"; this fixes a typo in
1218         the previous change.
1219
1220         Various maintainer cleanups.
1221         * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
1222         conftest*, for benefit of CVS commands run at the same time as
1223         "configure".  Add build-aux, since "bootstrap" now creates it and
1224         its subfiles.
1225         * Makefile.cfg (move_if_change): Remove.
1226         * Makefile.maint: Remove the update stuff; we now use "bootstrap".
1227         (ftp-gnu, www-gnu, move_if_change, local_updates, update):
1228         (po_repo, do-po-update, po-update, wget_files, get-targets):
1229         (config.guess-url_prefix, config.sub-url_prefix):
1230         (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
1231         (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
1232         ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
1233         Remove.
1234         * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
1235         this is now the recommended name.
1236         * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
1237         depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
1238         ylwrap.  These files now go into build-aux.
1239         * config/move-if-change: Remove.
1240         * config/prev-version.txt: Bump from 1.75 to 2.0.
1241
1242         * bootstrap: Add stdio-safer, unistd-safer modules.
1243         Remove m4/glibc2.m4 (introduced by latest gnulib, but
1244         we don't need it).
1245         * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
1246         fopen-safer.c, stdio-safer.h, unistd-safer.h.
1247         * lib/subpipe.c: Include "unistd-safer.h".
1248         (create_subpipe): Make sure all the newly-created
1249         file descriptors are > 2, so that diagnostics don't
1250         get sent down them (which might cause Bison to hang, in theory).
1251         * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
1252         * src/files.c (xfopen): Use fopen_safer, not fopen.
1253
1254         * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
1255         yesterday's yacc.c fix.
1256
1257 2005-05-21  Paul Eggert  <eggert@cs.ucla.edu>
1258
1259         * data/glr.c, data/lalr1.cc: Update copyright date.
1260
1261         Fix a destructor bug reported by Wolfgang Spraul in
1262         <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
1263         * data/yacc.c (yyabortlab): Don't call destructor, and
1264         don't set yychar to EMPTY.
1265         (yyoverflowlab): Don't call destructor.
1266         (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
1267         * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
1268         since we no longer output the message "discarding lookahead token
1269         end of input ()".
1270
1271 2005-05-20  Paul Hilfinger  <hilfingr@CS.Berkeley.EDU>
1272
1273         * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
1274         fix a small glitch in debugging output.
1275         (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
1276         after YY_SYMBOL_PRINT where needed.
1277
1278         (struct yyGLRState): Add some comments.
1279         (struct yySemanticOption): Add some comments.
1280         (union yyGLRStackItem): Add comment.
1281
1282         (yymergeOptionSets): Correct this to properly perform the union,
1283         avoiding infinite reported by Michael Rosien.
1284         Update comment.
1285
1286         * tests/glr-regression.at: Add test for GLR merging error reported
1287         by M. Rosien.
1288

1334         * tests/actions.at: Test that stack overflow invokes destructors.
1335         From Marcus Holland-Moritz.
1336         * data/yacc.c (yyerrlab): Move the code that destroys the stack
1337         from here....
1338         (yyreturn): to here.  That way, destructors are called properly
1339         even if the stack overflows, or the user calls YYACCEPT or
1340         YYABORT.  Stack-overflow problem reported by Marcus Holland-Moritz.
1341         (yyoverflowlab): Destroy the lookahead.

1348
1349         * NEWS: Bison-generated C parsers no longer quote literal strings
1350         associated with tokens.
1351         * src/output.c (prepare_symbols): Don't escape strings,
1352         since users don't want to see C escapes.
1353         * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
1354         in diagnostics.
1355         * tests/input.at (Torturing the Scanner): Likewise.

1359
1360         * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
1361         the data size is known to be too small and we can't increase it.
1362         This works around an HP-UX 11.00 glitch reported by Andrew Benham.

1364 2005-04-15  Paul Eggert  <eggert@cs.ucla.edu>
1365
1366         * src/parse-gram.y: Include quotearg.h.
1367         (string_as_id): Quote $1 before using it as a key, since the
1368         lexer no longer quotes it for us.
1369         (string_content): Don't strip quotes, since lexer no longer
1370         quotes it for us.
1371         * src/scan-gram.l: Include quotearg.h.
1372         ("\""): Omit quote.
1373         ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
1374         a key, since the rest of the lexer doesn't quote it.
1375         * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
1376         * tests/regression.at (Token definitions): Check for backslashes
1377         in token strings.
1378
1379         * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
1380         (YYSIZE_T): Define to unsigned long int when using an older compiler.
1381         (yyparse): Revamp code to generate long syntax error message, to
1382         make it easier to translate, and to avoid problems with arithmetic
1383         overflow.  Change "virtual memory" to "memory" in diagnostic, since
1384         we don't know whether the memory is virtual.

1387
1388         * NEWS: Bison-generated C parsers now use the _ macro to
1389         translate strings.
1390         * data/yacc.c (_) [!defined _]: New macro.
1391         All English strings wrapped inside this macro.
1392         * doc/bison.texinfo (Bison Parser): Document _.
1393         * po/POTFILES.in: Include src/parse-gram.c, since it now
1394         includes translateable strings that parse-gram.y doesn't.

1399         reverting the 2004-10-11 change to this function.
1400         (symbol_check_alias_consistency): Don't call symbol_type_set

1405
1406         * tests/regression.at (Token definitions): Don't use a token named
1407         c, as that generates a "#define c ..." that runs afoul of buggy
1408         stdlib.h that uses the identifier c as a member of struct
1409         drand48_data.  Problem reported by Horst Wente.

1419
1420         * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options

1424
1425         * tests/glr-regression.at (glr-regr2a.y): Try to dump core

1448
1449         * src/output.c (escaped_output): Renamed from

1451         well.  All uses changed.
1452         (symbol_destructors_output, symbol_printers_output):

1489         with dollar signs in test names.
1490         * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",

1517 2005-01-21  Paul Eggert  <eggert@cs.ucla.edu>
1518
1519         * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
1520         keyword; it's not needed with modern compilers, and it doesn't
1521         affect correctness with older compilers.  Suggested by
1522         twlevo@xs4all.nl.

1537
1538         * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),

1562
1563         * src/scan-skel.l ("@output ".*\n): Don't close standard output.
1564         Problem reported by Hans Aberg.
1565         * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
1566         (Output file names.): Add a test for the case when standard output

1570
1571         * doc/bison.texinfo (@copying): Update FDL version number to 1.2,

1573
1574 2004-12-25  Paul Eggert  <eggert@cs.ucla.edu>
1575
1576         * NEWS: Version 2.0.  Reformat the existing news items since
1577         1.875, so that related items are grouped together.
1578         * configure.ac (AC_INIT): Bump version to 2.0.
1579         * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
1580
1581         * tests/torture.at (Exploding the Stack Size with Alloca): Set
1582         YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
1583         otherwise, we're not testing alloca.  Unfortunately there's no
1584         simple way to consult HAVE_ALLOCA here.
1585
1586         * data/lalr1.cc (yydestruct_): Pacify unused variable warning
1587         for yymsg, too.
1588
1589         * src/LR0.c (new_itemsets): Use memset rather than zeroing by
1590         hand.  This avoids a warning about comparing int to size_t when
1591         GCC warnings are enabled.
1592
1593 2004-12-22  Paul Eggert  <eggert@cs.ucla.edu>
1594
1595         * NEWS: Bison-generated parsers no longer default to using the
1596         alloca function (when available) to extend the parser stack, due
1597         to widespread problems in unchecked stack-overflow detection.
1598         * data/glr.c (YYMAXDEPTH): Remove undef when zero.  It's the user's
1599         responsibility to set it to a positive value.  This lets the user
1600         specify a value that is not a preprocessor constant.
1601         * data/yacc.c (YYMAXDEPTH): Likewise.
1602         (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
1603         * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
1604         to be a compile-time constant.  However, explain the constraints on it.
1605         Also, explain the constraints on YYINITDEPTH.
1606         (Table of Symbols): Explain that alloca is no longer the default.
1607         Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
1608         to 1.
1609
1610         * doc/bison.texinfo (Location Default Action): Mention that n must
1611         be zero when k is zero.  Suggested by Frank Heckenbach.

1617         Private, not public.
1618         (parser::parse): Return ints, not bool.
1619         Returning a bool introduces a problem: 0 corresponds to false, and
1620         it seems weird to return false on success.  Returning true changes
1621         the conventions for yyparse.
1622         Alternatively we could return void and send an exception.
1623         There is no clear consensus (yet?).
1624         (state_stack, semantic_stack, location_stack): Rename as...
1625         (state_stack_type, semantic_stack_type, location_stack_type): these.
1626         Private, not public.
1627         * tests/c++.at: New.

1637
1638         * data/lalr1.cc (b4_filename_type): New.
1639         (position::filename): Use it.
1640         (parser.hh): Move the inclusion of stack.hh and location.hh below
1641         the user code, so that needed headers for the filename type can be
1642         included first.
1643         Forward declare them before the user code.
1644         * tests/Makefile.am (check-local, installcheck-local): Pass
1645         TESTSUITEFLAGS to the TESTSUITE.
1646
1647 2004-12-20  Akim Demaille  <akim@epita.fr>

1662

1667
1668         Remove uses of 'short int' and 'unsigned short int'.  This raises
1669         some arbitrary limits.  It uses more memory but nowadays that's
1670         not much of an issue.
1671
1672         This change does not affect the generated parsers; that's a different
1673         task, as some users will want to conserve memory there.
1674
1675         Ideally we should use size_t to represent all object counts, and
1676         something like ptrdiff_t to represent signed differences of object
1677         counts; but that will require more code-cleanup than I have the
1678         time to do right now.
1679
1680         * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):

1704         (error_): Rename as...
1705         (error): this, since it is visible to the user.
1706         Adjust callers.
1707         (Parser::message): Now an automatic variable from...
1708         (Parser::yyreport_syntax_error_): here.

1739         * data/lalr1.cc (yylex): Use #define to select the name of yylex,
1740         so that one can refer to yylex in the parser file, and have it
1741         renamed, as is the case with other skeletons.
1742
1743 2004-12-16  Akim Demaille  <akim@epita.fr>

1766
1767         Fix some problems reported by twlevo at xs4all.
1768         * src/symtab.c (symbol_new): Report an error if the input grammar
1769         contains too many symbols.  This is better than calling abort() later.
1770         * src/vcg.h (enum layoutalgorithm): Remove.  All uses removed.
1771         (struct node, struct graph):
1772         Rename member expand to stretch.  All uses changed.

1795
1796 2004-12-15  Akim Demaille  <akim@epita.fr>
1797
1798         Simplify the C++ parser constructor.
1799
1800         * data/lalr1.cc (debug_): Rename as...
1801         (yydebug_): so that the parser's internals are always in the yy*
1802         pseudo namespace.
1803         Adjust uses.
1804         (b4_parse_param_decl): Remove the leading comma as it is now only
1805         called as unique argument list.
1806         (Parser::Parser): Remove the constructor accepting a location and
1807         an initial debugging level.
1808         Remove from the other ctor the argument for the debugging level.
1809         (debug_level_type, debug_level, set_debug_level): New.
1810
1811         * tests/actions.at, tests/calc.at, tests/regression.at: Adjust

1814 2004-12-15  Akim Demaille  <akim@epita.fr>
1815
1816         Remove b4_root related material: failure experiment
1817         (which goal was to allow to derive from a class).
1818
1819         * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
1820         definitions and uses.

1823
1824         * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
1825         not 2, since it's not portable to subtract 1 from the start of an
1826         array.  The new item 0 is never set or used.  All uses changed.
1827
1828         (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
1829         the default definition of YYLLOC_DEFAULT.  Problem reported
1830         by Frank Heckenbach.
1831
1832 2004-12-12  Paul Eggert  <eggert@cs.ucla.edu>
1833
1834         * data/glr.c (YYRHSLOC): Don't have two definitions, one for
1835         the normal case and one for the error case.  Just use the
1836         first one uniformly.  Problem reported by Frank Heckenbach.
1837         (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
1838         use exactly the same macro in both places.
1839         (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
1840         so that the normal-case YYRHSLOC works for the error case too.
1841         All uses changed.
1842         * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
1843         (YYLLOC_DEFAULT): Use the same macro as glr.c.
1844         * doc/bison.texinfo (Location Default Action): Don't claim that
1845         we have an array of locations.  Use the same macro for both glr
1846         and lalr parsers.  Mention YYRHSLOC.  Mention what happens when
1847         the index is 0.

1859
1860         * src/scan-skel.l: Include "complain.h", for "fatal".
1861
1862         * src/relation.h (relation_print, relation_digraph):
1863         Relation sizes are of type relation_node, not size_t (this is
1864         merely a doc fix, since the two types are equivalent).
1865         (relation_transpose): Relation sizes are of type relation_node,
1866         not int.
1867         * src/relation.c: Likewise.

1870
1871         * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
1872         with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
1873         (yyparse): Remove unused local introduced in 2004-10-25 patch.
1874
1875         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
1876         specifying whether the test should be skipped.  Use it tp
1877         specify that the [%defines %skeleton "lalr1.cc"] tests currently
1878         fail on some hosts, and should be skipped.
1879
1880 2004-12-08  Paul Eggert  <eggert@cs.ucla.edu>
1881
1882         * src/system.h (CALLOC, MALLOC, REALLOC): Remove.  All callers
1883         changed to use xcalloc, xnmalloc, xnrealloc, respectively,
1884         unless otherwise specified below.
1885
1886         * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
1887         to allocate kernel_base, kernel_items, kernel_size, since
1888         they needn't be initialized to 0.
1889         (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
1890         * src/closure.c (new_closure): Likewise, for itemset.
1891         * src/derives.c (derives_compute): Likewise, for delts, derives, q.

1908         (tables_generate): Likewise for width.
1909
1910         * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
1911         for initial core.  Just have a separate core, so we needn't worry
1912         about whether kernel_size and kernel_base are initialized.
1913
1914         * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
1915         kernel_size, kernel_items): Remove unnecessary initialization.
1916         * src/conflicts.c (conflicts): Likewise.

1922         Likewise.
1923
1924         * src/closure.c (new_closure): Arg is of type unsigned int, not int.
1925         This is because all callers pass unsigned int.
1926         * src/closure.h (new_closure): Likewise.
1927
1928         * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
1929         (build_relations): Initialize includes[i] in all cases.
1930         * src/reader.c (packgram): Always initialize rules[ruleno].prec
1931         and rules[ruleno].precsym.  Initialize members in order.
1932         * src/relation.c (relation_transpose): Always initialize new_R[i]
1933         and end_R[i].
1934         * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
1935
1936         * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
1937         conflict_list[0] was always 0, but now it isn't initialized.
1938
1939         * src/table.c (table_grow): When conflict_table grew, the grown
1940         area wasn't cleared.  Fix this.
1941
1942         * lib/.cvsignore: Add strdup.c, strdup.h.
1943         * m4/.cvsignore: Add strdup.m4.

1946
1947         * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
1948         * src/lalr.c (set_goto_map): Don't allow ngotos to equal
1949         GOTO_NUMBER_MAXIMUM, since we occasionally compute
1950         ngotos + 1 without checking for overflow.
1951         (build_relations): Use END_NODE, not -1, to denote end of edges.
1952         * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
1953         build_relations): Use goto_number, not int, for goto numbers.
1954         * src/tables.c (save_column, default_goto): Likewise.
1955
1956 2004-11-23  Akim Demaille  <akim@epita.fr>
1957
1958         * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
1959         of #defining from yystype.
1960         Don't typedef yystype, C++ does not need it.
1961         This lets it possible to forward declare it as union.

1964
1965         * bootstrap (gnulib_modules): Add extensions.

1982
1983         * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
1984         changes.
1985         (YYCDEBUG): Adjust.
1986         Use it instead of cdebug_.
1987         (Parser::debug_stream, Parser::set_debug_stream): New.
1988         (Parser::symprint_): Define cdebug_ for temporary backward
1989         compatibility.
1990         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use

1994
1995         * data/lalr1.cc (Parser:print_): Remove, use %printer instead.

1997         * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
1998         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.

2003         Problem reported by Frank Heckenbach.
2004
2005 2004-10-25  Akim Demaille  <akim@epita.fr>
2006
2007         * data/glr.c (YYRHSLOC): Move its definition next to its uses.
2008         Introduce another definition to address simple location arrays.
2009         (yyGLRStack): New member: yyerror_range.
2010         (yyrecoverSyntaxError, yyparse): Update it.
2011         (yyrecoverSyntaxError): Use it when shifting the error token to
2012         have an accurate range, equivalent to the one computed by both
2013         yacc.c and lalr1.cc.
2014         * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
2015         that column numbers start at column 0, as per GNU Coding
2016         Standards, the others tests, and the doc.
2017         (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
2018         Adjust to the above change (first column is 0).
2019         And adjust the location of the "<error>", now covering the whole
2020         line.
2021

2023         and Paul Eggert  <eggert@cs.ucla.edu>
2024
2025         Remove some arbitrary limits on goto numbers and relations.
2026         * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
2027         initial values, since they're never used.
2028         (set_goto_map): ngotos is now unsigned, so test for overflow
2029         by seeing whether it wraps around to zero.
2030         * src/lalr.h (goto_number): Now size_t, not short int.
2031         (GOTO_NUMBER_MAXIMUM): Remove.
2032         * src/relation.c (relation_print, traverse, relation_transpose):
2033         Check for END_NODE rather than looking at sign.

2035         (relation_node): Now size_t, not short int.
2036

2038
2039         * doc/bison.texinfo (Language and Grammar): In example, "int" is a
2040         keyword, not an identifier.  Problem reported by Baron Schwartz in
2041         <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.

2044
2045         * src/symtab.c (symbol_check_alias_consistency): Also check
2046         type names, destructors, and printers.
2047         Reported by Alexandre Duret-Lutz.
2048         Recode the handling of associativity and precedence in terms
2049         of symbol_precedence_set.
2050         Accept no redeclaration at all, not even equal to the previous
2051         value.
2052         (redeclaration): New.
2053         Use it to factor redeclaration complaints.
2054         (symbol_make_alias): Don't set the type of the alias, let
2055         symbol_check_alias_consistency do it as for other features.
2056         * src/symtab.h (symbol): Add new member prec_location, and
2057         type_location.
2058         * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.

2062
2063         .cvsignore fixes to accommodate gnulib changes,
2064         and the practice of naming build directories "_build".
2065         * .cvsignore: Add "_*".  Sort.
2066         * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
2067         * m4/.cvsignore: Add "*_gl.m4".

2072         spaces.
2073
2074 2004-10-05  Akim Demaille  <akim@epita.fr>
2075
2076         In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
2077         whether the reducion was empty or not.  This leaves room to
2078         improve the use of YYLLOC_DEFAULT in such a case.
2079         lalr1.cc is still experimental, so changing this is acceptable.
2080         And finally, there are probably not many users who changed the
2081         handling of locations in GLR, so changing is admissible too.
2082
2083         * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
2084         empty reduction, set @$ to an empty location ending the previously
2085         stacked symbol.
2086         Adjust uses to make sure the code is triggered on empty
2087         reductions.
2088         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
2089         expected output: empty reductions have empty locations.
2090
2091 2004-09-29  Akim Demaille  <akim@epita.fr>
2092
2093         * data/lalr1.cc: Move towards a more standard C++ coding style
2094         for templates: Class < T > -> Class<T>.
2095
2096 2004-09-29  Akim Demaille  <akim@epita.fr>
2097
2098         * data/lalr1.cc: Reinstall the former ctor, for sake of
2099         compatibility, but warn it will be removed.
2100         Move towards a more standard C++ coding style (i.e., type *var ->
2101         type* var).
2102
2103 2004-09-27  Paul Eggert  <eggert@cs.ucla.edu>
2104
2105         * src/parse-gram.y (add_param): Rewrite to avoid strchr,
2106         since it's less likely to work if NULs are involved in the future.
2107
2108 2004-09-27  Akim Demaille  <akim@epita.fr>
2109
2110         * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
2111
2112 2004-09-27  Akim Demaille  <akim@epita.fr>
2113
2114         * data/lalr1.cc (b4_parse_param_decl_1): New.
2115         (b4_parse_param_decl): Use it to have different names between attribute
2116         and argument names.
2117         (b4_cc_constructor_call): Likewise.
2118
2119 2004-09-24  Akim Demaille  <akim@epita.fr>
2120
2121         * src/parse-gram.y (add_param): Strip the leading and trailing
2122         blanks from a formal argument declaration.
2123         (YY_LOCATION_PRINT): New.
2124
2125 2004-09-24  Akim Demaille  <akim@epita.fr>
2126
2127         * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
2128         after the location.
2129
2130 2004-09-24  Akim Demaille  <akim@epita.fr>
2131
2132         * doc/bison.texinfo (Table of Symbols): Sort.
2133
2134 2004-09-21  Akim Demaille  <akim@epita.fr>
2135
2136         * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
2137         the useless parentheses.
2138         Suggested by Paul Eggert.
2139
2140 2004-09-20  Akim Demaille  <akim@epita.fr>
2141
2142         Let the initial-action act on the look-ahead, and use it for the
2143         "initial push" (corresponding to an hypothetical beginning-of-file).
2144         And let lalr1.cc honor %initial-action.
2145
2146         * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
2147         example.
2148         * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
2149         (Parser::Parser): Remove the ctor that used to initialize it.
2150         (Parser::parse): Like in the other skeletons, issue the "starting
2151         parse" message before any action.
2152         Honor %initial-action.
2153         Initialize the stacks with the lookahead.
2154         * data/yacc.c: Let $$ and @$ in %initial-action designate the
2155         look-ahead.
2156         Push them in the stacks.
2157         * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
2158
2159 2004-09-20  Akim Demaille  <akim@epita.fr>
2160
2161         * doc/bison.texinfo (Initial Action Decl): New.
2162
2163 2004-09-20  Akim Demaille  <akim@epita.fr>
2164
2165         * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
2166         clearer criterion to define it.
2167         (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
2168         When reducing on an empty RHS, use the latest stacked location as
2169         location.
2170         yylloc is not always available.
2171         * data/glr.c: Likewise.
2172         Also, honor initial-actions.
2173
2174 2004-09-20  Akim Demaille  <akim@epita.fr>
2175
2176         * data/yacc.c (YY_LOCATION_PRINT): New.
2177         Define when we know YYLTYPE's structure, i.e., when the default
2178         YYLLOC_DEFAULT is used.
2179         * data/c.m4 (b4_yysymprint_generate): Use it.
2180         * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
2181         value of the result.
2182         (error_start_): Replace with...
2183         (error_range_): this location array.
2184         This allows to replace code relying on the implementation of
2185         locations by portable code.
2186         * data/yacc.c (yylerrsp): Replace with...
2187         (yyerror_range): this.
2188         Every time a token is popped, update yyerror_range[0], to have an
2189         accurate location for the error token.
2190         * data/glr.c (YY_LOCATION_PRINT): New.
2191         (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
2192         deference a pointer.
2193         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
2194         report the location in %printers.
2195
2196         * src/scan-skel.l: Instead of abort, report error messages to ease
2197         understanding skeleton scanning failures.
2198
2199 2004-09-16  Akim Demaille  <akim@epita.fr>
2200
2201         * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
2202         (iterator, const_iterator): these, to be more in the C++ spirit.
2203         Also, return reverse iterators so that when displaying the stack
2204         we display its bottom first.
2205         (Parser::stack_print_, Parser::reduce_print_): Match the messages
2206         from yacc.c.
2207         We should probably use vector here though.
2208
2209 2004-09-16  Akim Demaille  <akim@epita.fr>
2210
2211         Have more complete shift traces.
2212
2213         * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
2214         to report Shifts instead of ad hoc YYDPRINTF invocations,
2215         including for the error token.
2216         * data/lalr1.cc (symprint_): Output the location.
2217         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
2218         output the location within the %printer.
2219         Activate GLR tests, at least to make sure they compile properly.
2220         They still don't pass though.
2221         * tests/calc.at: Adjust expect verbose output, since now "Entering
2222         state..." is on a different line than the "Shifting" message.
2223
2224 2004-09-08  Akim Demaille  <akim@epita.fr>
2225
2226         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
2227         Bison directive from the Bison file to the invocation of this
2228         macro, so that these directives are passed to
2229         AT_BISON_OPTION_PUSHDEFS to get correct help macros.
2230         Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
2231         Move the AT_SETUP/AT_CLEANUP outside, to report as test title
2232         the extra Bison directives instead of the whole series.
2233         Change the grammar so that there are recoverable errors, and
2234         unrecoverable errors.  Now we can have the parser give up before
2235         consuming the whole input.  As a result we now can observe that
2236         the lookahead is freed when needed.
2237         Change the parser source to parse argv[1] instead of a hard coded
2238         string.
2239         Simplify yylex, and give a value and location to EOF.
2240         Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
2241         passed directives already coded in the file.
2242         Add some tests to check the location of "error".
2243         For some tests, the C++ parser is correct, and not yacc.c.
2244         For other tests, they provide different, but unsatisfying, values,
2245         so keep the C++ value so that at least one parser is "correct"
2246         according to the test suite.
2247         (Actions after errors): Remove, this is subsumed by the
2248         AT_CHECK_PRINTER_AND_DESTRUCTOR series.
2249
2250 2004-09-06  Akim Demaille  <akim@epita.fr>
2251
2252         * data/lalr1.cc: Adjust the indentation of the labels.
2253         (Parser::pop): New.
2254         Use it.
2255
2256 2004-09-06  Akim Demaille  <akim@epita.fr>
2257
2258         * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
2259         argument, an informative message.
2260         Call YY_SYMBOL_PRINT.
2261         Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
2262         * data/lalr1.cc (destruct_): Likewise.
2263         In addition, no longer depend on b4_yysymprint_generate and
2264         b4_yydestruct_generate to generate these functions, do it "by
2265         hand".
2266
2267 2004-09-03  Akim Demaille  <akim@epita.fr>
2268
2269         * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
2270         invoked, yydestruct the lookahead.
2271         * tests/calc.at (Calculator $1): Update the expected lengths of
2272         traces: there is an added line for the discarded lookahead.

2311
2312         Adjust to latest gnulib.
2313         * bootstrap (gnulib_modules): Add xalloc-die.
2314         Set LC_ALL=C so that file names sort consistently.
2315         Prefer the gnulib copies of gettext.m4, glibc21.m4,
2316         inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,

2320
2321 2004-08-10  Florian Krohm  <florian@edamail.fishkill.ibm.com>
2322
2323         * src/scan-action.l: Remove. Scanning of semantic actions is

2334
2335         Fix bug with non-%union parsers that have printers or destructors,
2336         which led to a Bison core dump.  Reported by Peter Fales in
2337         <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
2338

2340         * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
2341         not to our own type.
2342         * src/output.c (symbol_destructors_output, symbol_printers_output):
2343         Don't assume %union.

2346         UNION-FLAG.  All callers changed.
2347         (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
2348         Use type char, not unsigned int, when declaring an array of char;
2349         this lets us remove a cast.
2350         (Printers and Destructors): Add non-%union test cases.
2351
2352 2004-06-21  Paul Eggert  <eggert@cs.ucla.edu>
2353
2354         * doc/bison.texinfo: Minor editorial changes, mostly to the new
2355         GLR writeups.  E.g., avoid frenchspacing and the future tense,
2356         change "lookahead" to "look-ahead", and change "wrt" to "with
2357         respect to".
2358
2359 2004-06-21  Paul Hilfinger  <hilfingr@CS.Berkeley.EDU>
2360
2361         * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
2362         New sections, split off from the GLR Parsers section.  Put the new
2363         Simple GLR Parser near the start of the GLR section, for clarity.
2364         Rewrite connective text.
2365
2366 2004-06-21  Frank Heckenbach  <frank@g-n-u.de>

2371
2372         * NEWS, TODO, doc/bison.texinfo:
2373         Use "look-ahead" instead of "lookahead", to be consistent.
2374         * REFERENCES: Fix incorrect reference to DeRemer and Pennello,

2402         (trivial change).
2403         * configure.ac (O0CXXFLAGS): New var.
2404         * tests/atlocal.in (CXXFLAGS): Use it.

2425
2426         Spent a few hours checking out which prerequisite versions the
2427         current sources actually require.  I went all the way back to
2428         Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
2429         a seemingly endless set of combinations of versions more recent
2430         than that.  The bottom line is that the current sources require
2431         fairly recent versions of the build tools, and it'll be some work
2432         to change this.
2433         * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
2434         (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
2435         (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
2436         Add comments explaining why those particular versions are
2437         currently needed.
2438
2439         * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
2440         in SGI MIPSpro 7.4.1m.  Problem reported by Albert Chin-A-Young in
2441         <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
2442
2443         * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
2444         (it fails with a Autoconf-without-aclocal-m4 diagnostic).
2445
2446 2004-05-26  Paul Eggert  <eggert@cs.ucla.edu>
2447
2448         * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
2449         0.11.5.  Suggested by Bruno Haible.
2450         * bootstrap: Remove gettext version checking.
2451
2452         * doc/bison.texinfo (Decl Summary): Also mention that %union
2453         can depend on prerequisite types.  Problem reported by Tim
2454         Van Holder.
2455
2456 2004-05-25  Paul Eggert  <eggert@cs.ucla.edu>
2457
2458         * README: Mention GNU m4 1.4 bugs and Akim's patched version.
2459         * README-alpha: Don't tell people not to package this.
2460
2461         * bootstrap: Don't assume $(...) works; use `...` instead.
2462         Problem reported by Paul Hilfinger.  Also, diagnose non-GNU
2463         gettext better.
2464
2465         * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
2466         put into the -d output file, and mention what to do if YYSTYPE is
2467         defined as a macro.
2468
2469 2004-05-24  Paul Eggert  <eggert@cs.ucla.edu>
2470
2471         Undo change made earlier today: it caused autopoint to not bring
2472         in ABOUT-NLS.  Ouch.  Instead, substitute our own diagnostic for
2473         autopoint's.
2474
2475         * bootstrap: Check that gettext version matches what's in
2476         configure.ac.  Warn users to ignore robots.txt ERROR 404.
2477         * bootstrap: Undo today's earlier change (logged below).
2478         * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
2479
2480         The gettext version checking is causing more trouble than it's
2481         curing; remove it.  Problem reported by Paul Hilfinger.
2482
2483         * bootstrap: Issue a warning that one can expect a message
2484         'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
2485         * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.

2487 2004-05-23  Paul Eggert  <eggert@cs.ucla.edu>
2488
2489         Ensure that the C++ compiler used for testing actually works on a
2490         simple test program; if not, skip the C++-related tests.  Problem
2491         reported by Vin Shelton in:
2492         http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html

2500
2501         * data/glr.c (yylloc): Output this macro even if locations are not
2502         being generated, as the GLR parser needs it even in that case.
2503         Problem reported by Troy A. Johnson
2504         <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
2505
2506         * configure.ac (AC_INIT): Update to 1.875e.
2507
2508 2004-05-21  Paul Eggert  <eggert@cs.ucla.edu>

2511         * configure.ac (AC_INIT): Likewise.
2512         * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
2513
2514         * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
2515         -Wmissing-prototypes, or -Wstrict-prototypes for C++.  The current
2516         lalr1.cc runs afoul of the first, and the last two are no longer
2517         supported by GCC 3.4.0.
2518         * README: Mention GNU m4 1.4 or later; mention m4 patches.
2519         * HACKING: Use ./bootstrap, not "make update" to import foreign files.

2522

2541
2542         * NEWS: Document %expect-rr.
2543
2544         * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
2545         Fix typo by replacing $1 with $option.
2546         Remove more 'intl'-related files.
2547         Don't DEFUN AM_INTL_SUBDIR twice.
2548
2549         * lib/.cvsignore: Add strndup.h.  Remove memchr.c, memcmp.c,

2554         xstrndup.m4.  Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,

2563
2564         Get files from the gnulib and po repositories, instead of relying
2565         on them being in our CVS.  Upgrade to latest versions of gnulib
2566         and Automake.
2567
2568         * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
2569         * bootstrap: Bootstrap from gnulib and po repositories.
2570         Much of this code was stolen from GNU diff and GNU tar's bootstrap.
2571         * README-cvs: Document these changes.  Remove version numbers from
2572         mentions of build tools, since they change so often.  Mention Flex.
2573
2574         * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
2575         (gl_USE_SYSTEM_EXTENSIONS): Add.
2576         (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
2577         Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
2578         does this for us.
2579         (AC_ISC_POSIX): Remove; we no longer support this
2580         ancient OS, as it gets in the way of latest Autoconf & gnulib.
2581         (AC_HEADER_STDC): Remove: we now assume C89 or better.
2582         (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
2583         Do not check for C89 headers, except for locale.h which is used
2584         by the Yacc library and must port to K&R hosts.
2585         (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
2586         Do not check for C89 functions, except for setlocale which is
2587         used by the Yacc library.
2588         (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.

2593         AM_GNU_GETTEXT): Remove; now done by:
2594         (GNULIB_AUTOCONF_SNIPPET): Add.  "bootstrap" builds this for us.
2595         (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
2596         for us.
2597
2598         * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
2599         (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
2600         Define to empty, as gnulib.mk will do the rest for us.
2601         ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
2602         for us.
2603         (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
2604         (lib_SOURCES): New symbol, containing only the non-gnulib libs.

2607
2608         * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
2609         (REALLOC): Use xnrealloc, for likewise.
2610         (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
2611         (strnlen, memrchr): Remove decls; functions no longer used.
2612         Include <stpcpy.h>.

2636         by bootstrap or automake.
2637
2638         * po/ChangeLog: Remove: all but one entry was a duplicate
2639         of this file, and I moved that 2000-11-02 entry here.
2640
2641         * config/.cvsignore: Add Makefile, depcomp, install-sh.
2642         * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

2658         * src/.cvsignore: Remove *_.c.
2659
2660
2661         * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
2662         support it.  (The latest stable gzip doesn't.)
2663
2664 2004-04-27  Paul Eggert  <eggert@twinsun.com>
2665
2666         * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
2667         case, as stos_ is now used by destructors due to the 2004-02-09
2668         change.
2669
2670         Remove more K&R C support.
2671         * lib/libiberty.y (PARAMS): Remove.  All uses removed.
2672         * lib/subpipe.c (errno): Remove decl.
2673         Include <stdlib.h> unconditionally.
2674         (EXIT_FAILURE): Remove macro.
2675         * src/complain.c (vfprintf, strerror): Remove.
2676         * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
2677         unconditionally.
2678         (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
2679         Use latest Autoconf recommendations for including inttypes.h, stdint.h.
2680         (strchr, strspn, memchr): Remove decls.
2681         * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
2682         unconditionally.  Do not declare perror.
2683         * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
2684         unconditionally.
2685
2686         * src/complain.c (_): Remove useless defn, as system.h defines this.
2687
2688         * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
2689         with latest obstack.h.
2690         * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
2691         to procedure types, as obstack.h now does that for us.

2693
2694         * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
2695         so that this include file can stand alone.
2696         * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
2697         does this now.  Include subpipe.h first after config.h, to
2698         test whether it can stand alone.
2699
2700         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
2701         declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
2702         unused declaration.
2703
2704         * tests/synclines.at (%union synch line): Put a dummy member in
2705         the union, because empty unions aren't allowed in C.  Caught
2706         by GCC 3.4.0.
2707
2708 2004-04-13  Jim Meyering  <jim@meyering.net>
2709
2710         * src/conflicts.c (conflicts_print): Correct format string typo:
2711         use `%%' to produce literal `%'.  (trivial change)
2712
2713 2004-03-30  Paul Eggert  <eggert@twinsun.com>
2714
2715         * src/getargs.c (version): Update copyright year to 2004.
2716
2717         * data/c.m4 (b4_int_type): Use 'short int' rather than
2718         'short', and similarly for 'long', 'unsigned', etc.
2719         * data/glr.c (YYTRANSLATE, yyconfl, yySymbol, yyItemNum,
2720         yygetLRActions, yyprocessOneStack, yyrecoverSyntaxError,
2721         yy_yypstack, yydumpstack): Likewise.

2735         Likewise.
2736         * src/LR0.c (allocate_itemsets): Likewise.
2737         * src/gram.h (rule_number, rule): Likewise.
2738         * src/lalr.h (goto_number): Likewise.

2753
2754 2004-03-25  Paul Hilfinger  <hilfingr@tully.CS.Berkeley.EDU>
2755
2756         * src/parse-gram.y: Define PERCENT_EXPECT_RR.
2757         (declaration): Replace expected_conflicts with expected_sr_conflicts.
2758         Add %expect-rr rule.
2759
2760         * src/scan-gram.l: Recognize %expect-rr.
2761
2762         * src/conflicts.h (expected_sr_conflicts): Rename from
2763         expected_conflicts.
2764         (expected_rr_conflicts): Declare.
2765
2766         * src/conflicts.c (expected_sr_conflicts): Rename from
2767         expected_conflicts.
2768         (expected_rr_conflicts): Define.
2769         (conflicts_print): Check r/r conflicts against expected_rr_conflicts
2770         for GLR parsers.
2771         Use expected_sr_conflicts in place of expected_conflicts.
2772         Warn if expected_rr_conflicts used in non-GLR parser.
2773
2774         * doc/bison.texinfo: Add documentation for %expect-rr.
2775
2776 2004-03-08  Paul Eggert  <eggert@gnu.org>
2777
2778         Add support for hex token numbers.  Suggested by Odd Arild Olsen in
2779         <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
2780
2781         * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
2782         in lalr1.cc.
2783         * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
2784         * src/scan-gram.l (scan_integer): New function.
2785         ({int}): Use it.
2786         (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
2787         (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
2788         handle_action_dollar, handle_action_at, convert_ucn_to_byte):
2789         Say "long int", not "long", for uniformity with GNU style.
2790
2791 2004-02-25  Paul Eggert  <eggert@twinsun.com>
2792
2793         * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
2794         compilers.  This fixes a problem with Intel's C++ compiler being
2795         chatty, reported by Guido Trentalancia in
2796         <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
2797
2798 2004-02-09  Alexandre Duret-Lutz  <adl@gnu.org>
2799
2800         Support %destructor and merge error locations in lalr1.cc.
2801
2802         * data/lalr1.cc (b4_cxx_destruct_def): New macro.
2803         (Parser::stos_): Define unconditionally.
2804         (Parser::destruct_): New method.  Generate its body with
2805         b4_yydestruct_generate.
2806         (Parser::error_start_): New attribute.
2807         (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
2808         token which are discarded.
2809         (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
2810         error_start_ when erroneous token are discarded.
2811         (Parser::parse) <yyerrlab1>: Compute the location of the error
2812         token so that it covers all the discarded tokens.
2813         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
2814         it can be called with `%skeleton "lalr1.cc"', and do that.
2815
2816 2004-02-02  Paul Eggert  <eggert@twinsun.com>
2817
2818         * src/Makefile.am (AM_CPPFLAGS): New macro.  It mentions
2819         $(top_srcdir)/lib and ../lib.  This fixes a bug reported
2820         by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
2821         There's no need to mention top_builddir since Automake does that
2822         for us.
2823         (INCLUDES): Remove, as Automake says it's obsolescent.
2824         Contents migrated into AM_CPPFLAGS as described above.
2825         * lib/Makefile.am (INCLUDES): Remove; obsolescent.
2826
2827 2004-01-14  Paul Hilfinger  <hilfingr@CS.Berkeley.EDU>
2828
2829         * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
2830         (yyreportSyntaxError): Handle case where lookahead token is
2831         YYEMPTY.
2832
2833 2004-01-13  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
2834
2835         * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
2836         resulting parsers are compilable with C++.
2837
2838 2003-12-23  Paul Eggert  <eggert@twinsun.com>
2839
2840         * config/depcomp, config/install-sh: Sync with Automake 1.8.
2841         * src/output.c (output_skeleton): Rename local var.
2842         * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
2843         Bison tokens, as this runs afoul of the 2003-10-07 change that
2844         disallowed NUL bytes in character constants or string literals.
2845
2846         * tests/local.at: Require Autoconf 2.59's Autotest.
2847         * tests/testsuite.at: Don't include local.at, since we now assume
2848         Autoconf 2.59 or later.  Autoconf 2.59 had some problems with
2849         including it.
2850         * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
2851         multiple inclusion warnings.
2852
2853 2003-12-02  Akim Demaille  <akim@epita.fr>
2854
2855         * doc/bison.texinfo (How Can I Reset the Parser): More about start
2856         conditions.
2857         From Bruno Haible.
2858
2859 2003-11-18  Alexandre Duret-Lutz  <adl@gnu.org>
2860
2861         * doc/bison.texinfo (Bison Options): Escape `@' in `$@'.
2862
2863 2003-10-07  Paul Eggert  <eggert@twinsun.com>
2864
2865         * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
2866         if testsuite doesn't exist.
2867
2868         * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
2869         literals, unfortunately.
2870         * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
2871         Complain about NUL bytes in character constants or string literals.
2872
2873 2003-10-05  Paul Eggert  <eggert@twinsun.com>
2874
2875         * NEWS: Don't document %no-default-prec, as it's still
2876         too experimental.
2877         * doc/bison.texinfo: Document %no-default-prec only if
2878         the defaultprec flag is set.  Normally it's not.
2879
2880 2003-10-04  Paul Eggert  <eggert@twinsun.com>
2881
2882         * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
2883         non-modifiable lvalue, instead of a modifiable one.

2947
2948         When reducing initial empty rules, Bison parser read an initial
2949         location that is not defined.  This results in garbage, and that
2950         affects Bison's own parser.  Therefore we need (i) to extend Bison
2951         to support a means to initialize this location, and (ii) to use
2952         this CVS Bison to fix CVS Bison's parser.
2953
2954         * src/reader.h, reader.c (epilogue_augment): Remove, replace
2955         with...
2956         * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
2957         * src/parse-gram.y: Adjust.
2958         (%initial-action): New.
2959         (%error-verbose): Since we require CVS Bison, there is no reason
2960         not to use it.
2961         * src/scan-gram.l: Adjust.
2962         * src/Makefile.am (YACC): New, to make sure we use our own parser.
2963         * data/yacc.c (yyparse): Use b4_initial_action.

2965 2003-08-25  Akim Demaille  <akim@epita.fr>

2989
2990         Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
2991         error recovery loops.  This patch is based on
2992         <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
2993         Also, augment the similarity between lalr1.cc and yacc.c.
2994         Note: the locations of error recovery rules are not correct yet.
2995
2996         * data/lalr1.cc: Comment changes to augment the similarity between
2997         lalr1.cc and yacc.c.
2998         (YYERROR): Goto to yyerrorlab, not yyerrlab1.
2999         (yyerrlab1): Remove, but where it used to be (now the bottom part of
3000         yyerrlab), when hitting EOF, pop the whole stack here instead of
3001         merely falling thru the default error handling mechanism.
3002         (yyerrorlab): New label, with the old contents of YYERROR,
3003         plus the following change: pop the stack of rhs corresponding
3004         to the production that invoked YYERROR.  That is how Yacc
3005         behaves (required by POSIX).
3006         * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
3007         fail.
3008
3009 2003-08-25  Akim Demaille  <akim@epita.fr>
3010
3011         Tune local.at so that people can "autom4te -l autotest calc.at -o
3012         calc" for instance, to extract a sub test suite.
3013
3014         * tests/testsuite.at: Move the initialization, Autotest version
3015         requirement, and AT_TESTED invocation into...
3016         * tests/local.at: here.
3017         * tests/testsuite.at: Include it for compatibility with Autoconf
3018         2.57.
3019         * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
3020         be ignore.

3023
3024         Rework code slightly to avoid gcc -Wtraditional warnings.
3025         * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
3026         The returned value is now stored in *YY0.  All callers changed.
3027         * src/output.c (merge_output): Adjust to the above change.

3032         (yyfillin, yydoAction, yyglrReduce, yysplitStack,
3033         yyresolveStates, yyprocessOneStack):
3034         Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.

3038
3039         * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
3040         for portability to K&R C (after ansi2knr, presumably).  See
3041         <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
3042         by Frank Heckenbach, though I have omitted the structure-initialization
3043         part of his glr-knr.diff patch since I recall that the Portable
3044         C Compiler didn't require that change.
3045
3046         Let the user specify how to allocate and free memory.

3049         * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
3050         All uses of free, malloc, realloc changed to use these macros,
3051         and unnecessary casts removed.
3052         * data/yacc.c (YYFREE, YYMALLOC): Likewise.

3066

3069         * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
3070         * data/yacc.c (YYLLOC_DEFAULT): Likewise.
3071         Remove unnecessary parentheses from uses.
3072         * doc/bison.texinfo (Location Default Action): Describe the
3073         conventions for parentheses.

3076
3077         * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
3078         yyreportTree): Do not assume that size_t is the same width as int,
3079         when printing sizes.  Print sizes using an unsigned format.
3080         Problem reported by Frank Heckenbach in
3081         <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
3082
3083         Port to Forte Developer 7 C compiler.
3084         * data/glr.c (struct YYLTYPE): If locations are not being used,
3085         declare a single dummy member, as empty structs do not conform
3086         to the C standard.
3087         (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
3088         the Forte Developer 7 C compiler complains that end-of-loop
3089         code is not reached.

3104         * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
3105         Don't use 'index' in comments, as it's a builtin fn on some hosts.
3106         * lib/bitset_stats.c: Include gettext.h unconditionally, as
3107         per recent gettext manual's suggestion.
3108         * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):

3131         from libbitset.
3132
3133         * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
3134         `How Can I Reset @code{yyparse}', since texinfo does not allow
3135         arbitrary @ in node names.
3136
3137         * m4/Makefile.am (EXTRA_DIST): Add the following files, which
3138         shouldn't be needed according to the gettext 0.12.1 documentation
3139         but which seem to be needed anyway: codeset.m4 glibc21.m4

3148         * stdbool_.h: File renamed from stdbool.h.in.

3151         (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
3152         (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
3153         * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
3154         (MOSTLYCLEANFILES): New var.
3155         ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).

3163         (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
3164         the tests right now.
3165         * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
3166         yyerror are declared before use; C99 requires this.
3167
3168 2003-06-09  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
3169
3170         * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
3171         first.
3172         (yyrecoverSyntaxError): Correct the logic for setting and testing
3173         yyerrState.
3174         Correct comment on handling EOF.
3175         Allow states with only a default reduction, rather than failing
3176         (I can't quite reconstruct why these were not allowed before).
3177
3178         Fixes to avoid problem that $-N rules in GLR parsers can cause
3179         buffer overruns, corrupting state.
3180
3181         * src/output.c (prepare_rules): Output max_left_semantic_context

3187         (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
3188         (yyresolveAction): Ditto.
3189
3190         Fixes to problems with location handling in GLR parsers reported by
3191         Frank Heckenbach (2003/06/05).
3192
3193         * data/glr.c (YYLTYPE): Make trivial if locations not used.
3194         (YYRHSLOC): Add parentheses, and define only if locations used.
3195         (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
3196         locations not used.
3197         (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
3198         (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
3199
3200         * tests/cxx-type.at: Exercise location information; update tests
3201         to differentiate output with and without locations.
3202         Remove forward declarations of yylex and yyerror---caused errors
3203         because default YYLTYPE not yet defined.
3204         Change semantic actions to compute strings, rather than printing
3205         them directly (to test proper passing of semantics values).  Change
3206         output to prefix notation and update test data and expected results.
3207         (yylex): Track locations.
3208         (stmtMerge): Return value rather than printing, and include arguments
3209         in value.

3213         Avoid warnings generated by GCC 2.95.4 when Bison is
3214         configured with --enable-gcc-warnings.
3215         * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
3216         yy::]b4_parser_class_name[::translate_,
3217         yy::Stack::operator[] (unsigned),
3218         yy::Stack::operator[] (unsigned) const,
3219         yy::Slice::operator[] (unsigned),
3220         yy::Slice::operator[] (unsigned) const):
3221         Rename local vars to avoid warnings.
3222         * tests/glr-regression.at (Improper handling of embedded actions
3223         and $-N in GLR parsers): Remove unused local variable from yylex.
3224         * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
3225         (void) as arg when not pure, since we now assume C89 when building
3226         Bison.  Pacify GCC by using parameter.
3227
3228 2003-06-02  Paul Eggert  <eggert@twinsun.com>
3229
3230         * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
3231         yy::Location::lines, yy::Location::columns): Rename arguments
3232         to avoid shadowing; this removes a warning generated by GCC 3.3.
3233
3234 2003-06-01  Paul Eggert  <eggert@twinsun.com>
3235
3236         Don't pass C-only warning optins (e.g., -Wmissing-declarations)
3237         to g++, as GCC 3.3 complains if you do it.
3238         * configure.ac (WARNING_CXXFLAGS): New subst.  Set it to
3239         everything that WARNING_CFLAGS has, except omit warnings
3240         not suitable for C++.
3241         (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
3242         * tests/atlocal.in (CXXFLAGS): New var.
3243         * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
3244
3245         Fix a GLR parser bug I reported in February; see
3246         <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
3247         The problem was that GLR parsers did not conform to the C standard,
3248         because actions like { $1 = $2 + $3; } expanded to expressions
3249         that invoked YYFILL in separate subexpressions, and YYFILL assigned
3250         to a local variable.  The C standard says that expressions
3251         like (var = f ()) + (var = f ()) have undefined behavior.
3252         Another problem was that GCC sometimes issues warnings that
3253         yyfill and its parameters are unused.
3254
3255         * data/glr.c (yyfillin): Renamed from the old yyfill.  Mark
3256         as possibly unused.
3257         (yyfill): New function.
3258         (YYFILL): Use it.
3259         (yyuserAction): Change type of yynormal to bool, so that it matches
3260         the new yyfill signature.  Mark it as possibly unused.
3261
3262
3263         Follow up on a bug I reported in February, where a Bison-generated
3264         parser can loop.  Provide a test case and a fix for yacc.c.  I
3265         don't have a fix for lalr1.cc or for glr.c, unfortunately.
3266         The original bug report is in:
3267         <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
3268
3269         * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
3270         macro's size was becoming unwieldy.
3271         (yyerrlab): Do not discard an empty lookahead symbol, as this
3272         might destroy garbage.
3273         (yyerrorlab): New label, with the old contents of YYERROR,
3274         plus the following change: pop the stack of rhs corresponding
3275         to the production that invoked YYERROR.  That is how Yacc
3276         behaves, and POSIX requires this behavior.
3277         (yyerrlab1): Use YYPOPSTACK instead of its definiens.
3278         * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
3279         Define 'alarm' to do nothing if unistd.h is not available.
3280         Add a new rule "exp: '-' error;" to test the above change to
3281         data/yacc.c.  Use 'alarm' to abort any test taking longer than
3282         10 seconds, as it's probably looping.
3283         (AT_CHECK_CALC): Test recovery from error in new grammar rule.
3284         Also, the new yacc.c generates two fewer diagnostics for an
3285         existing test.
3286
3287 2003-05-24  Paul Eggert  <eggert@twinsun.com>
3288
3289         * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
3290         YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
3291         This fixes a problem reported by John Bowman when the Compaq/HP
3292         Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
3293         -ansi -Wall -gall).
3294         * data/yacc.c (union yyalloc): Likewise.
3295         (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
3296
3297         Switch from 'int' to 'bool' where that makes sense.
3298
3299         * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
3300         abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,

3324         * lib/bbitset.h: Include <stdbool.h>.
3325         (struct bitset_vtable): The following members now return bool, not
3326         int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
3327         and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,

3329         * src/conflicts.c (count_rr_conflicts): Likewise.
3330         * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.

3361
3362         * src/parse-gram.y (rules_or_grammar_declaration): Require a
3363         semicolon after a grammar declaration, in the interest of possible
3364         future changes to the Bison input language.
3365         Do not allow a stray semicolon at the start of the grammar.
3366         (rhses.1): Allow one or more semicolons after any rule, including
3367         just before "|" as required by POSIX.
3368         * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
3369         grammar.

3371 2003-05-14  Alexandre Duret-Lutz  <adl@gnu.org>
3372
3373         %parse-param support for lalr1.cc.
3374
3375         * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
3376         b4_cc_constructor_calls, b4_cc_constructor_call,
3377         b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
3378         definitions.
3379         (yy::b4_parser_class_name::b4_parser_class_name): Take extra
3380         parse-param arguments.
3381         (yy::b4_parser_class_name): Declare instance variables to
3382         hold parse-param arguments.
3383         * tests/calc.at: s/value/semantic_value/ because value clashes
3384         with a member of yy::b4_parser_class_name.  Adjust C++ code
3385         to handle %parse-param.  Enable %parse-param test in C++.
3386
3387 2003-05-12  Paul Eggert  <eggert@twinsun.com>
3388
3389         * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
3390         English a bit.  Fix fclose typo.  Change "const char" to "char
3391         const", and use ANSI C rather than K&R for "main".  Suggest
3392         YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
3393         and suggest yy_switch_to_buffer.
3394
3395 2003-05-05  Paul Eggert  <eggert@twinsun.com>
3396
3397         * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
3398         C89.  This avoids a diagnostic on compilers that define __STDC__
3399         to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
3400         <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.

3405         Do not overrun array bounds.
3406         This should fix a bug reported today by Olatunji Oluwabukunmi in

3413         (nondeterministic_parser): New.
3414         * src/parse-gram.y, src/scan-gram.l: Support
3415         %nondeterministic-parser.
3416         * src/output.c (prepare): Use nondeterministic_parser instead
3417         of glr_parser where appropriate.

3429         Markovitch below.
3430
3431 2003-04-28  Tim Van Holder <tim.van.holder@pandora.be>
3432

3445
3446         * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
3447         Declare to be of type suitable for the ninf value itself, not of
3448         type suitable for the corresponding table, since the latter might
3449         be unsigned but the ninf value might be negative.  This fixes a
3450         bug reported by Alexandre Duret-Lutz in
3451         <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
3452
3453         * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
3454         invokes it.  We shouldn't invoke it twice because it will attempt
3455         to put error.o in the archive twice.  This fixes a glitch reported
3456         by Martin Mokrejs in

3465
3466         * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
3467         Fix obvious typo that results in uncompilable GLR parsers
3468         when both %pure-parser and %locations are used.  (trivial change)
3469
3470 2003-04-17  Paul Eggert  <eggert@twinsun.com>
3471
3472         * src/scan-gram.l: Add %option nounput, since we no longer use unput.
3473         (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
3474         Do not insert the expected token via unput, as this runs afoul
3475         of a POSIX-compatibility bug in flex 2.5.31.
3476         All uses changed to BEGIN the parent state,
3477         since we no longer insert the expected token via unput.
3478         * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
3479         that is no longer emitted after the above change.
3480
3481         * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
3482         the first one.  This change is from Paul Hilfinger, and it fixes
3483         regression reported by Werner Lemberg in
3484         <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
3485
3486         (resolve_sr_conflict): Don't invoke state_errs_set
3487         unless one or more tokens have been explicitly made errors.
3488         Otherwise, the above change causes Bison to abort.
3489
3490         * tests/existing.at (GNU pic Grammar): New test case, taken from
3491         Lemberg's email.

3505         From Paul Hilfinger.
3506
3507 2003-03-29  Akim Demaille  <akim@epita.fr>
3508
3509         * m4/error.m4: Do not put under dynamic conditions some code which
3510         expansion is under static control.
3511
3512 2003-03-29  Akim Demaille  <akim@epita.fr>
3513
3514         * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
3515
3516 2003-03-29  Akim Demaille  <akim@epita.fr>
3517

3521
3522         * .cvsignore: Add configure.lineno.
3523         * src/.cvsignore: Add yacc.
3524         * tests/.cvsignore: Add testsuite.log.
3525         * doc/fdl.texi: Sync with latest FSF version.

3527 2003-03-12  Paul Eggert  <eggert@twinsun.com>
3528
3529         * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
3530         (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
3531         cursor, instead of leaving it undefined.  This fixes a bug
3532         reported by Tim Van Holder in
3533         <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
3534         * tests/input.at (Torturing the Scanner): Test the scanner on
3535         an empty input file, which was Tim Van Holder's test case.
3536
3537         * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
3538         <sys/resource.h> can be included, include sys/time.h and
3539         sys/times.h first, if available.  This works around the SunOS
3540         4.1.4 porting bug reported by Bruce Becker in
3541         <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
3542
3543         * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
3544         AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
3545         AC_HEADER_SYS_WAIT.
3546
3547         Merge changes from gnulib.  This was prompted because the CVS
3548         snapshot didn't build on Solaris 7 due to strnlen problems.
3549
3550         These changes need to be merged back into gnulib:
3551         * lib/hash.c: Include <stdbool.h> unconditionally.
3552         * m4/onceonly.m4 (m4_quote): New macro.
3553         (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
3554         Quote AC_FOREACH variable-expansions properly.
3555         The 2003-01-03 obstack.h change also needs merging.
3556         {end of changes requiring merging}
3557

3563         New files, imported from gnulib.
3564         * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
3565         above.
3566

3568         m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
3569         gnulib sources.

3587         * src/system.h: Include <stdbool.h> unconditionally.
3588
3589         * lib/bbitset.h: Include <limits.h> unconditionally.  We have been
3590         assuming at least C89 in the bitset code for some time now.

3596 2003-03-02  Akim Demaille  <akim@epita.fr>
3597
3598         * doc/bison.texinfo (Table of Symbols): Reactivate the
3599         documentation for %lex-param, and %parse-param.
3600
3601 2003-03-02  Akim Demaille  <akim@epita.fr>
3602
3603         * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
3604         generate verbose error messages.
3605         Use the number of tokens as an upper bound in yytname, as it
3606         cannot be a non terminal.
3607
3608 2003-03-02  Akim Demaille  <akim@epita.fr>
3609
3610         * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
3611         message.
3612
3613 2003-03-02  Akim Demaille  <akim@epita.fr>
3614
3615         * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
3616         Use them to exercise yycheck overrun.
3617         Based on Andrew Suffield's grammar.
3618
3619 2003-03-02  Akim Demaille  <akim@epita.fr>
3620
3621         Create tests/local.at for Bison generic testing macros.
3622
3623         * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
3624         * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
3625         This new file.
3626         * tests/calc.at (AT_CHECK_CALC): Adjust.
3627         * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)

3629         * tests/local.at: here.
3630         (AT_COMPILE_CXX): Tags the tests using it as c++.
3631         Ignore the test if CXX is not functional.
3632
3633 2003-03-01  Paul Eggert  <eggert@twinsun.com>
3634
3635         * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
3636         not loc->end, since loc->end might contain garbage and this leads
3637         to undefined behavior on some platforms.
3638         (id_loc, token_start): Use (IF_LINTed) initial values that do not
3639         depend on *loc, so that the reader doesn't give the the false
3640         impression that *loc is initialized.
3641         (<INITIAL>"%%"): Do not bother setting code_start, since its value
3642         does not survive the return.
3643
3644 2003-03-01  Akim Demaille  <akim@epita.fr>
3645
3646         * src/scan-gram.l (code_start): Always initialize it when entering
3647         into yylex, as SC_EPILOGUE is activated *before* the corresponding
3648         yylex invocation.  An alternative would be making it static, but
3649         then it starts with the second %%'s beginning, instead of its end.
3650
3651 2003-02-28  Paul Eggert  <eggert@twinsun.com>
3652
3653         * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
3654         around a UnixWare 7.1.1 porting bug reported by John Hughes in
3655         <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
3656

3658
3659         * README: Mention compiler bug in Sun Forte Developer 6 update 2.
3660         Remove Sequent/Pyramid discussion (nobody uses them any more).
3661         Merge VMS and MS-DOS discussion; these ports may well be dead
3662         but let's keep mentioning them for now.  Put <> around email
3663         addresses.  Add copyright notice.

3682 2003-02-21  Akim Demaille  <akim@epita.fr>
3683
3684         * doc/bison.texinfo: Use "location" consistently to refer to @n,
3685         to avoid confusions with lalr1.cc's notion of Position.
3686         Suggested by Paul Eggert.
3687
3688 2003-02-20  Akim Demaille  <akim@epita.fr>
3689
3690         * data/lalr1.cc (position.hh): Make sure "columns" never pushes
3691         before initial_columns.
3692         (location.hh): Use consistent variable names when defining the
3693         operator<<.
3694         Use "last" so that we subtract from Positions, not from unsigned.
3695
3696 2003-02-20  Akim Demaille  <akim@epita.fr>
3697
3698         * data/lalr1.cc (position.hh): New subfile, including the extended
3699         and Doxygen'ed documentation of class Position.

3708         Redefine AT_YYERROR_SEES_LOC_IF using it.
3709         (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
3710         not defined.
3711         Don't use the location in yy::Parser::error_ and
3712         yy::Parser::print_ when not %locations.
3713         Activate more lalr1.cc tests.
3714
3715 2003-02-19  Akim Demaille  <akim@epita.fr>
3716
3717         * data/lalr1.cc: When displaying a line number, be sure to make it

3721

3728
3729         * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
3730         error recovery, mixing with/without pops and discarding of the
3731         lookahead.
3732         Exercise YYERROR.
3733         Disable the lalr1.cc tests as currently it doesn't support YYERROR.
3734
3735 2003-02-17  Paul Eggert  <eggert@twinsun.com>

3743
3744         * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
3745         Avoid subscript error in yycheck.  Bug reported by Andrew Suffield in
3746         <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.

3750
3751         The bug still remains in data/lalr1.cc, as I didn't have time
3752         to fix it there.

3768         iterator names.
3769         (operator<< (Location)): New.

3775         lalr1.cc is used.

3777         column 0.
3778         Change all the expected results.
3779         Conform to the GCS: simplify the locations when applicable.

3828         * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
3829         char * var.
3830
3831         * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
3832         var.
3833
3834         * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
3835         var.
3836
3837         * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
3838         Use str, not s, for char * var.  Use ch, not c, for character var.
3839         Use size for size var.
3840
3841         * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
3842         char * var.
3843         (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
3844         uniqstr var.
3845         * src/uniqstr.h: Likewise.
3846
3847         * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
3848         get_layoutalgorithm_str, get_decision_str, get_orientation_str,
3849         get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
3850         get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
3851         param to have same name as that of enum, so that we don't use
3852         "s" to stand for a non-state.
3853
3854 2003-02-02  Akim Demaille  <akim@epita.fr>
3855
3856         * src/scan-skel.l: Scan more than one inert character per yylex
3857         invocation.
3858
3859 2003-02-01  Paul Eggert  <eggert@twinsun.com>
3860
3861         Version 1.875a.
3862
3863         * po/LINGUAS: Add ms.
3864
3865 2003-01-30  Akim Demaille  <akim@epita.fr>
3866
3867         * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
3868
3869 2003-01-29  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
3870
3871         * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
3872         of $1.
3873
3874         Changes in response to error report by S. Eken: GLR mode does not
3875         handle negative $ indices or $ indices in embedded rules correctly.
3876         See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
3877
3878         * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
3879         (b4_rhs_location): Ditto.
3880         (yyfill): New function to copy from stack tree into array
3881         incrementally.
3882         (yyuserAction): Modify to allow incremental move of semantic values
3883         to rhs array when in GLR mode.
3884         Define YYFILL to use in user-defined actions to fill semantic array
3885         as needed.
3886         Remove dummy use of yystack, as there is now a guaranteed use.
3887         (yydoAction): Modify to allow incremental move of semantic values
3888         to rhs array when in GLR mode.
3889         (yyresolveAction): Ditto.
3890         (yyglrShiftDefer): Update comment.
3891         (yyresolveStates): Use X == NULL for pointers, not !X.
3892         (yyglrReduce): Ditto.
3893         (yydoAction): Ditto
3894
3895         * tests/glr-regr1.at: Rename to ...
3896         * tests/glr-regression.at: Add new regression test for the problems
3897         described above (adapted from S. Eken).
3898         Update copyright notice.
3899         * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
3900         * tests/Makefile.am: Ditto.
3901
3902 2003-01-28  Paul Eggert  <eggert@twinsun.com>
3903
3904         * data/lalr1.cc: Do not use @output_header_name@ unless
3905         b4_defines_flag is set.  This fixes two bugs reported by
3906         Tim Van Holder in
3907         <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
3908         and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
3909
3910 2003-01-21  Paul Eggert  <eggert@twinsun.com>
3911
3912         * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
3913         we don't need to worry about yyerrlab1 being reported as an
3914         "unused label" by non-GCC C compilers.  The downside is that if
3915         locations are used then a couple of statements are duplicated each
3916         time YYERROR is invoked, but the upside is that the warnings
3917         should vanish.
3918         (yyerrlab1): Move code to YERROR.
3919         (yyerrlab2): Remove.  Change uses back to yyerrlab1.
3920         This reverts some of the 2002-12-27 change.
3921
3922 2003-01-17  Paul Eggert  <eggert@twinsun.com>
3923
3924         * src/output.c (symbol_printers_output): Fix typo that led
3925         to core dump.  Problem reported by Antonio Rus in
3926         <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
3927
3928 2003-01-13  Akim Demaille  <akim@epita.fr>,
3929                 Quoc Peyrot <chojin@lrde.epita.fr>,
3930                 Robert Anisko <anisko_r@lrde.epita.fr>
3931
3932         * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
3933         when the stacks contain one element, as the loop would otherwise
3934         free the last state, and then use the top state (the one we just
3935         popped).  This means that the initial elements will not be freed
3936         explicitly, as is the case in yacc.c; it is not a problem, as
3937         these elements have fake values.
3938
3939 2003-01-11  Paul Eggert  <eggert@twinsun.com>
3940
3941         * NEWS: %expect-violations are now just warnings, reverting
3942         to Bison 1.30 and 1.75 behavior.  This fixes the GCC 3.2
3943         bootstrapping problem reported by Matthias Klose; see
3944         <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
3945         * src/conflicts.c (conflicts_print): Likewise.
3946         * tests/conflicts.at (%expect not enough, %expect too much,
3947         %expect with reduce conflicts): Likewise.
3948         * doc/bison.texinfo (Expect Decl): Document this.  Also mention
3949         that the warning is enabled if the number of conflicts changes
3950         (not necessarily increases).
3951
3952         * src/getargs.c (version): Update copyright year.
3953
3954 2003-01-09  Akim Demaille  <akim@epita.fr>
3955
3956         * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
3957
3958 2003-01-08  Paul Eggert  <eggert@twinsun.com>
3959
3960         * Makefile.maint (WGETFLAGS):
3961         New macro, containing "-C off" to disable proxy caches.
3962         All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
3963         (rel-check): Use $(WGET) instead of wget.
3964
3965 2003-01-06  Paul Eggert  <eggert@twinsun.com>
3966
3967         * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
3968         the GLR paper of Scott, Johnstone and Hussain.
3969
3970 2003-01-04  Paul Eggert  <eggert@twinsun.com>
3971
3972         * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
3973         (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
3974         * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
3975         (EXTRA_LIBRARIES): New var, for liby.a.
3976         * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
3977         (EXTRA_SCRIPTS): New var, for yacc.
3978
3979         * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
3980         since GNU C++ (as of 3.2.1) does not allow attributes on labels.
3981         Problem reported by Nelson H. F. Beebe.
3982
3983 2003-01-03  Paul Eggert  <eggert@twinsun.com>
3984
3985         * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
3986         (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
3987         when compiling Bison 1.875's `bitset bset = obstack_alloc
3988         (bobstack, bytes);'.  Problem reported by Nelson H. F. Beebe.
3989
3990         * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
3991         ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
3992         grow to a huge size with typical invocation.
3993
3994         * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
3995         Use the pattern recommended by Autoconf 2.57, except also protect
3996         against double-definition.
3997         * src/system.h: Likewise.
3998         Portability issues reported by Nelson H. F. Beebe.
3999
4000         * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
4001         All uses changed.  Provide a definition in both C and C++.
4002         (yytrue, yyfalse): Define even if defined (__cplusplus).
4003
4004         * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
4005         Reported by Nelson H. F. Beebe.
4006
4007         * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
4008
4009 2003-01-02  Paul Eggert  <eggert@twinsun.com>
4010
4011         * data/yacc.c (yyerrlab1): Append `;' after attribute, to
4012         pacify the buggy "smart preprocessor" in MacOS 10.2.3.
4013         Bug reported by Nelson H. F. Beebe.
4014
4015 2003-01-01  Paul Eggert  <eggert@twinsun.com>
4016
4017         * Version 1.875.
4018
4019 2002-12-30  Paul Eggert  <eggert@twinsun.com>
4020
4021         * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
4022         Moved here from...
4023         (<INITIAL>","): Here.  This causes stray "," to be treated
4024         more uniformly.
4025
4026         * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
4027         last brace in braced code when not in Yacc mode, for compatibility
4028         with Bison 1.35.  This resurrects the 2001-12-15 patch to
4029         src/reader.c.
4030
4031         * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
4032         yystype.  This follows up the 2002-12-24 YYSTYPE bug fix.
4033
4034 2002-12-28  Paul Eggert  <eggert@twinsun.com>
4035
4036         * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
4037         that of SYM's type.  This fixes Debian bug 168069, reported by
4038         Thomas Olsson.
4039
4040 2002-12-28  Paul Eggert  <eggert@twinsun.com>
4041
4042         Version 1.75f.
4043
4044         Switch back to the Yacc style of conflict reports, undoing some
4045         of the 2002-07-30 change.
4046         * doc/bison.texinfo (Understanding): Use Yacc style for
4047         conflict reports.  Also, use new way of locating rules.
4048         * src/conflicts.c (conflict_report):
4049         Renamed from conflict_report_yacc, removing the old
4050         'conflict_report'.  Translate the entire conflict report at once,
4051         so that we don't assume that "," has the same interpretation in
4052         all languages.
4053         (conflicts_output): Use Yacc-style conflict report for each state,
4054         instead of our more-complicated style.
4055         (conflicts_print): Use Yacc-style conflict report, except print
4056         the input file name when not emulating Yacc.
4057         * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
4058         Conflicted Reduction, %expect not enough, %expect too much,
4059         %expect with reduce conflicts): Switch to Yacc-style conflict reports.
4060         * tests/existing.at (GNU Cim Grammar): Likewise.
4061         * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
4062
4063         * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
4064         fatal): Don't invoke fflush; it's not needed and it might even be
4065         harmful for stdout, as stdout might not be open.
4066         * src/reduce.c (reduce_print): Likewise.
4067
4068 2002-12-27  Paul Eggert  <eggert@twinsun.com>
4069
4070         Fix a bug where error locations were not being recorded correctly.
4071         This problem was originally reported by Paul Hilfinger in
4072         <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
4073
4074         * data/yacc.c (yyparse): New local var yylerrsp, to record the
4075         top of the location stack's error locations.
4076         (yyerrlab): Set it.  When discarding a token, push its location
4077         onto yylerrsp so that we don't lose track of the error's end.
4078         (yyerrlab1): Now is only the target of YYERROR, so that we can
4079         properly record the location of the action that failed.  For GCC
4080         2.93 and later, insert an __attribute__ ((__unused__)) to avoid
4081         GCC warning about yyerrlab1 being unused if YYERROR is unused.
4082         (yyerrlab2): New label, which yyerrlab now falls through to.
4083         Compute the error's location by applying YYLLOC_DEFAULT to
4084         the locations of all the symbols that went into the error.
4085         * doc/bison.texinfo (Location Default Action): Mention that
4086         YYLLOC_DEFAULT is also invoked for syntax errors.
4087         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
4088         Error locations include the locations of all the tokens that were
4089         discarded, not just the last token.
4090
4091 2002-12-26  Paul Eggert  <eggert@twinsun.com>
4092
4093         * src/files.c: Include quote.h.
4094         (compute_output_file_names): Warn if we detect conflicting
4095         outputs to the same file.  This should catch the misunderstanding
4096         exemplified by Debian Bug 165349, reported by Bruce Stephens..
4097
4098         * src/conflicts.c (conflicts_print): If the user specifies
4099         "%expect N", report an error if there are any reduce/reduce
4100         conflicts.  This is what the manual says should happen.
4101         This fixes Debian bug 130890, reported by Anthony DeRobertis.
4102         * tests/conflicts.at (%expect with reduce conflicts): New test.
4103
4104         Don't use m4_include on relative file names, as it doesn't work as
4105         desired if there happens to be a file with that name under ".".
4106
4107         * m4sugar/version.m4: Remove; it was included but it wasn't used.
4108         * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
4109         * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
4110         * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
4111         * src/output.c (output_skeleton): Use full path names when
4112         specifying a file to include; don't rely on include path, as
4113         it's unreliable when the working file contains a file with
4114         that name.
4115
4116 2002-12-25  Paul Eggert  <eggert@twinsun.com>
4117
4118         Remove obsolete references to bison.simple and bison.hairy.
4119         Problem mentioned by Aubin Mahe in
4120         <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
4121         * data/glr.c: Comment fix.
4122         * doc/bison.1: Remove references.  Also, mention "yacc".
4123
4124         * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
4125         with -g option.
4126
4127         * src/parse-gram.y (declaration): Use enum "report_states" rather
4128         than its numeric value 1.
4129
4130         * src/scan-skel.l ("@output ".*\n): Close any old yyout before
4131         opening a new one.  This fixes Debian bug 165349, reported by
4132         Bruce Stephens.
4133
4134 2002-12-24  Paul Eggert  <eggert@twinsun.com>
4135
4136         Version 1.75e.
4137
4138         * Makefile.maint (cvs-update): Don't assume that the shell
4139         supports $(...), as Solaris sh doesn't.
4140
4141         * src/parse-gram.y (lloc_default): Remove test for empty
4142         nonterminals at the end, since it didn't change the result.
4143
4144 2002-12-24  Paul Eggert  <eggert@twinsun.com>
4145
4146         If the user does not define YYSTYPE as a macro, Bison now declares it
4147         using typedef instead of defining it as a macro.  POSIX requires this.
4148         For consistency, YYLTYPE is also declared instead of defined.
4149
4150         %union directives can now have a tag before the `{', e.g., the
4151         directive `%union foo {...}' now generates the C code
4152         `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
4153         The default union tag is `YYSTYPE', for compatibility with Solaris 9
4154         Yacc.  For consistency, YYLTYPE's struct tag is now `YYLTYPE'
4155         instead of `yyltype'.
4156
4157         `yystype' and `yyltype' are now obsolescent macros instead of being
4158         typedefs or tags; they are no longer documented and will be
4159         withdrawn in a future release.
4160
4161         * data/glr.c (b4_location_type): Remove.
4162         (YYSTYPE): Renamed from yystype.
4163         (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
4164         (struct YYLTYPE): Renamed from struct yyltype.
4165         (YYLTYPE): Renamed from yyltype.
4166         (yyltype, yystype): New (and obsolescent) macros,
4167         for backward compatibility.
4168         * data/yacc.c: Likewise.
4169
4170         * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
4171         does not specify a union tag.  This is for compatibility with
4172         Solaris 9 yacc.
4173
4174         * src/parse-gram.y (add_param): 2nd arg is now char * not char
4175         const *, since it is now modified by stripping surrounding { }.
4176         (current_braced_code): Remove.
4177         (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
4178         PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
4179         trailing " {...}".  Now of type <chars>.
4180         (grammar_declaration): Adjust to bundled tokens.
4181         (code_content): Remove; stripping is now done by add_param.
4182         (print_token_value): Print contents of bundled tokens.
4183         (token_name): New function.
4184
4185         * src/reader.h (braced_code, current_braced_code): Remove.
4186         (token_name): New decl.
4187
4188         * src/scan-gram.l (handle_dollar, handle_at): Now takes int
4189         token_type, not braced_code code_kind.  All uses changed.
4190         (SC_PRE_CODE): New state, for scanning after a keyword that
4191         has (or usually has) an immediately-following braced code.
4192         (token_type): New local var, to keep track of which token type
4193         to return when scanning braced code.
4194         (<INITIAL>"%destructor", <INITIAL>"%lex-param",
4195         <INITIAL>"%parse-param", <INITIAL>"%printer",
4196         <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
4197         instead of returning a token type immediately.
4198         (<INITIAL>"{"): Set token type.
4199         (<SC_BRACED_CODE>"}"): Use it.
4200         (handle_action_dollar, handle_action_at): Now returns bool
4201         indicating success.  Fail if ! current_rule; this prevents a core dump.
4202         (handle_symbol_code_dollar, handle_symbol_code_at):
4203         Remove; merge body into caller.
4204         (handle_dollar, handle_at): Complain in invalid contexts.
4205
4206         * NEWS, doc/bison.texinfo: Document the above.
4207         * NEWS: Fix years and program names in copyright notice.

4209 2002-12-17  Paul Eggert  <eggert@twinsun.com>
4210
4211         * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
4212         Reporting, Table of Symbols): Omit mentions of %lex-param and
4213         %parse-param from the documentation for now.

4217         Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
4218         GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
4219         lookahead symbol, and which sets yychar in parser actions) and it
4220         disagreed with the Bison documentation.  Bug
4221         reported by Andrew Walrond.
4222
4223         * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
4224         as the caller now does that.
4225         (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
4226         (YYEMPTY): Parenthesize right hand side, since others use it.
4227         (yyparse): Don't assume that our generated code is the only code
4228         that sets yychar.

4240
4241         * po/LINGUAS: Add da.
4242
4243         * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around

4261 2002-12-12  Paul Eggert  <eggert@twinsun.com>
4262
4263         Remove unportable casts and storage allocation tricks.
4264         While we're at it, remove almost all casts, since they
4265         usually aren't needed and are a sign of trouble.
4266
4267         * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
4268
4269         * src/derives.c (derives_compute): Do not subtract NTOKENS from
4270         the pointer DSET returned by malloc; this isn't portable.
4271         Instead, always use DSET[i - NTOKENS] rather than DSET[i].
4272         Similarly for DERIVES.
4273         * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
4274         * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
4275         * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
4276
4277         * src/derives.c (derives_compute): Do not bother invoking
4278         int_of_rule_number, since rule numbers are integers.
4279
4280         * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
4281         rather than XMALLOC (char, N).
4282
4283         * src/files.c (filename_split): Rewrite to avoid cast.
4284
4285         * src/gram.h (symbol_number_as_item_number,
4286         item_number_as_symbol_number, rule_number_as_item_number,
4287         item_number_as_rule_number):
4288         Now inline functions rather than macros, to avoid casts.
4289         * src/state.h (state_number_as_int): Likewise.
4290         * src/tables.c (state_number_to_vector_number,
4291         symbol_number_to_vector_number): Likewise.
4292
4293         * src/gram.h (int_of_rule_number): Remove; no longer used.
4294
4295         * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
4296         since the resulting storage is always stored into.
4297
4298         * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
4299         where it's needed.
4300
4301         * src/muscle_tab.c (muscle_m4_output):
4302         Now inline.  Return bool, not int.
4303         * src/state.c (state_compare): Likewise.
4304         * src/symtab.c (symbol_check_defined,
4305         symbol_check_alias_consistency, symbol_pack, symbol_translation,
4306         hash_compare_symbol, hash_symbol):
4307         Likewise.
4308         * src/uniqstr.c (uniqstr_print): Likewise.
4309         * src/muscle_tab.c (muscle_m4_output_processor):
4310         New function, to avoid casts.
4311         * src/state.c (state_comparator, stage_hasher): Likewise.
4312         * src/symtab.c (symbol_check_defined_processor,
4313         symbol_check_alias_consistency_processor, symbol_pack_processor,
4314         symbol_translation_processor, hash_symbol_comparator,
4315         hash_symbol_hasher): Likewise.
4316         * src/uniqstr.c (uniqstr_print_processor): Likewise.
4317         * src/muscle_tab.c (muscles_m4_output):
4318         Use new functions instead of casting old functions unportably.
4319         * src/state.c (state_hash_new): Likewise.
4320         * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
4321         symbols_token_translations_init):
4322         Likewise.
4323         * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
4324
4325         * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
4326         var instead of casting to long, to avoid casts.
4327         (prepare_states): Use MALLOC rather than alloca, so that we don't
4328         have to worry about alloca.
4329         * src/state.c (state_hash_lookup): Likewise.
4330
4331         * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
4332         local var instead of casting to unsigned char, to avoid casts.
4333
4334         * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
4335         STATE_ALLOC): Remove.
4336         (transitions_new, errs_new, reductions_new, state_new): Use malloc
4337         rather than calloc, and use offsetof to avoid allocating slightly
4338         too much storage.
4339         (state_new): Initialize all members.
4340
4341         * src/state.c (state_hash): Use unsigned accumulator, not signed.
4342
4343         * src/symtab.c (symbol_free): Remove; unused.
4344         (symbol_get): Remove cast in lhs of assignment.
4345         (symbols_do): Now static.  Accept generic arguments, not
4346         hashing-related ones.
4347
4348         * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
4349         (symbol_processor): Remove.
4350         (symbols_do): Remove decl; now static.
4351
4352         * src/system.h (alloca): Remove; decl no longer needed.
4353         (<stddef.h>): Include, for offsetof.
4354         (<inttypes.>, <stdint.h>): Include if available.
4355         (uintptr_t): New type, if system lacks it.
4356         (CALLOC, MALLOC, REALLOC): New macros.
4357         All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
4358         new macros.
4359
4360         * src/tables.c (table_size): Now int, to pacify GCC.
4361         (table_grow, table_ninf_remap): Use signed table size.
4362         (save_row): Don't bother initializing locals when not needed.
4363         (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
4364         * src/uniqstr.c (hash_compare_uniqstr):  Likewise.
4365
4366         * src/vcg.h: Correct misspellings.
4367

4369
4370
4371         * src/getargs.c (getargs): Don't assume EOF == -1.
4372
4373 2002-12-09  Paul Eggert  <eggert@twinsun.com>
4374
4375         Change identifier spellings to avoid collisions with names
4376         that are reserved by POSIX.
4377
4378         Don't use names ending in _t, since POSIX reserves them.
4379         For consistency, remove _e and _s endings -- they're weren't
4380         needed to remove ambiguity.  All uses changed.
4381         * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
4382         turn was just renamed from struniq_t.
4383         * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
4384         which in turn was just renamed from struniq_processor_t.
4385         (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
4386         in turn was renamed from hash_compare_struniq_t.

4408         * src/nullable.c (struct rule_list): Renamed from struct rule_list_s.

4457
4458         Don't include <errno.h> in the mainstream code, since it
4459         reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.

4463         * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
4464         * src/output.c (output_skeleton): Likewise.

4468         Likewise.
4469         (handle_action_dollar, handle_action_at): Likewise.
4470         * src/system.h: Do not include <errno.h>.
4471         (TAB_EXT): Renamed from EXT_TAB.
4472         (OUTPUT_EXT): Renamed from EXT_OUTPUT.
4473
4474         Avoid str[a-z]*, since <string.h> reserves that name space.
4475         Change all instances of "struniq" in names to "uniqstr", and
4476         likewise for "STRUNIQ" and "UNIQSTR".
4477         * src/uniqstr.c: Renamed from src/struniq.c.
4478         * src/uniqstr.h: Renamed from src/struniq.h.
4479         * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

4490         (N_EXPAND): Renamed from N_STRETCH.
4491
4492         Avoid *_MAX and *_MIN, since <limits.h> reserves that name space.
4493         * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
4494         * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):

4502         (ACTION_MAX): Remove; unused.
4503         (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
4504         Unnecessary casts removed from above defines.
4505
4506
4507         Fix misspelling in names.
4508         * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
4509         * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from

4511
4512
4513         * lib/timevar.c (timevar_report): Renamed from time_report,
4514         for consistency with other names.
4515         * lib/timevar.h (timevar_report): New decl.
4516         * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
4517
4518
4519         Sort include-file uses.
4520
4521         Reorder all include files under src to be in the order "system.h".
4522         then the ../lib include files in angle brackets (alphabetized),
4523         then the . include files in double-quotes (alphabetized).  Fix
4524         dependency breakages encountered in this process, as follows:
4525         * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
4526         * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
4527         * src/state.h: Include "symtab.h".
4528
4529 2002-12-08  Paul Eggert  <eggert@twinsun.com>
4530
4531         * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
4532         since this causes problems when __file__ contains character
4533         sequences like "@" that are treated specially by src/scan-skel.l.
4534         Instead, just use the file's basename.  This fixes the bug
4535         reported by Martin Mokrejs in
4536         <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
4537
4538 2002-12-06  Paul Eggert  <eggert@twinsun.com>
4539
4540         Add support for rules that do not have trailing semicolons, as
4541         POSIX requires.  Improve the quality of locations in Bison
4542         diagnostics.
4543
4544         * src/location.c: Include <quotearg.h>.
4545         (empty_location): Now const.
4546         (location_print): New function.  Follow the recommendation of the
4547         GNU Coding Standards for locations that span file boundaries.
4548         * src/location.h: Do not include <quotearg.h>; no longer needed.
4549         (boundary): New type.
4550         (location_t): Use it.  This allows locations to span file boundaries.
4551         All member uses changed: file -> start.file or end.file (as needed),
4552         first_line -> start.line, first_column -> start.column,
4553         last_line -> end.line, last_column -> end.column.
4554         (equal_boundaries): New function.
4555         (LOCATION_RESET, LOCATION_STEP): Remove.
4556         (LOCATION_PRINT): Remove.  All callers changed to use location_print.
4557         (empty_location): Now const.
4558         (location_print): New decl.
4559         * src/parse-gram.y (lloc_default): New function, which handles
4560         empty locations more accurately.
4561         (YYLLOC_DEFAULT): Use it.
4562         (%token COLON): Remove.
4563         (%token ID_COLON): New token.
4564         (rules): Use it.
4565         (declarations, rules): Remove trailing semicolon.
4566         (declaration, rules_or_grammar_declaration):
4567         Allow empty (";") declaration.
4568         (symbol_def): Remove empty actions; no longer needed.
4569         (rules_or_grammar_declaration): Remove trailing semicolon.
4570         (semi_colon.opt): Remove.
4571         * src/reader.h: Include location.h.
4572         (scanner_cursor): New decl.
4573         * src/reduce.c (nonterminals_reduce): Use warn_at rather than
4574         rolling our own.
4575         * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
4576         of *loc.
4577         (STEP): Remove.  No longer needed, now that adjust_location does
4578         the work.  All uses removed.
4579         (scanner_cursor): New var.
4580         (adjust_location): Renamed from extend_location.  It now sets
4581         *loc and adjusts the scanner cursor.  All uses changed.
4582         Don't bother testing for CR.
4583         (handle_syncline): Remove location arg; now updates scanner cursor.
4584         All callers changed.
4585         (unexpected_end_of_file): Now accepts start boundary of token or
4586         comment, not location.  All callers changed.  Update scanner cursor,
4587         not the location.
4588         (SC_AFTER_IDENTIFIER): New state.
4589         (context_state): Renamed from c_context.  All uses changed.
4590         (id_loc, code_start, token_start): New local vars.
4591         (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context.  Move all
4592         processing of Yacc white space and equivalents here.
4593         (<INITIAL>{id}): Save id_loc.  Begin state SC_AFTER_IDENTIFIER
4594         instead of returning ID immediately, since we need to search for
4595         a subsequent colon.
4596         (<INITIAL>"'", "\""): Save token_start.
4597         (<INITIAL>"%{", "{", "%%"): Save code_start.
4598         (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
4599         (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
4600         BEGIN context_state at end, not INITIAL.
4601         (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
4602         <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
4603         Return correct token start.
4604         (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
4605         the start of a character, string or multiline comment is found.
4606         * tests/conflicts.at (S/R in initial, Defaulted Conflicted
4607         Reduction): Adjust reported locations to match the more-precise
4608         results now expected.
4609         * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
4610         * tests/reduce.at (Useless Rules, Reduced Automaton,
4611         Underivable Rules): Likewise.
4612         * tests/regression.at (Invalid inputs): No longer `expecting ";"
4613         or "|"' now that so many other tokens are allowed by the new grammar.
4614
4615         * src/complain.h (current_file): Remove duplicate decl;
4616         current_file is now owned by files.h.
4617         * src/complain.c, src/scan-gram.l: Include files.h.
4618
4619 2002-12-06  Paul Eggert  <eggert@twinsun.com>
4620
4621         * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
4622         promotes to int; it might be unsigned int.
4623         * data/yacc.c (yy_reduce_print): Likewise.
4624
4625         * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
4626         be #defined in the prologue, not in the Bison declarations.
4627         This fixes Debian Bug 102878, reported by Shaul Karl.
4628
4629 2002-12-02  Paul Eggert  <eggert@twinsun.com>
4630
4631         * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
4632         * lib/strtoul.c: New file, from gnulib.
4633         This fixes a porting bug reported by Peter Klein in
4634         <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
4635
4636 2002-11-30  Paul Eggert  <eggert@twinsun.com>
4637
4638         * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
4639         and put only a forward declaration in the prologue.  This is for
4640         consistency with the other scanner helper functions.
4641
4642         Type clashes now generate warnings, not errors, since it
4643         appears that POSIX may allow some grammars with type clashes.
4644         * src/reader.c (grammar_current_rule_check): Warn about
4645         type clashes instead of complaining.
4646         * tests/input.at (Type Clashes): Expect warnings, not complaints.
4647
4648         Add Yacc library, since POSIX requires it.
4649         * doc/bison.texinfo (Yacc Library): New node.  Regenerate top menu.
4650         * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
4651         * lib/main.c, lib/yyerror.c: New files.
4652
4653         gram_error can be static; it need not be extern.
4654         * src/reader.h (gram_error): Remove decl.
4655         * src/parse-gram.y (gram_error): Now static.  Add static decl.
4656         (print_token_value): Omit parameter names from forward decl,
4657         for consistency.
4658
4659 2002-11-29  Paul Eggert  <eggert@twinsun.com>
4660
4661         * doc/bison.texinfo: Emphasize that yylex and yyerror must
4662         be declared before being used.  E.g., one should typically
4663         declare them in the prologue.  Use GNU coding style in examples.
4664         Put "const" consistently after the type it modifies.  Mention
4665         that C99 supports "inline".  Mention that yyerror traditionally
4666         returns "int".
4667
4668         %parse-param and %lex-param now take just one argument, the
4669         declaration; the argument name is deduced from the declaration.
4670
4671         * doc/bison.texinfo (Parser Function, Pure Calling, Error
4672         Reporting, Table of Symbols): Document this.
4673         * src/parse-gram.y (add_param): New function.
4674         (COMMA): Remove.
4675         (declaration): Implement new rule for %parse-param and %lex-param.
4676         * src/scan-gram.l: "," now elicits a warning, rather than being
4677         a token; this is more compatible with byacc.
4678         * tests/calc.at (Simple LALR Calculator): Adopt new convention.
4679
4680 2002-11-27  Paul Eggert  <eggert@twinsun.com>
4681
4682         Rename identifiers to avoid real and potential collisions.
4683
4684         * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
4685         to avoid collision with lex macro described by Bruce Lilly in
4686         <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
4687         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
4688         * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
4689         * src/parse-gram.y (print_token_value): Renamed from yyprint.
4690         All uses changed.
4691         (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove.  All uses changed.
4692         The name "yycontrol" violates the name space rules, and this stuff
4693         wasn't being used anyway.
4694         (input): Remove action; this stuff wasn't being used.
4695         (gram_error): Rename local variable yylloc -> loc.
4696         * src/reader.h (struct gram_control_s, gram_control_t): Remove.
4697         (YY_DECL): Don't use "yy" at start of local variables.
4698         All uses changed, e.g., yylloc -> loc.
4699         * src/scan-gram.l (STEP): Renamed from YY_STEP.  All uses changed.
4700         (STRING_GROW): Renamed from YY_OBS_GROW.  All uses changed.
4701         (STRING_FINISH): Renamed from YY_OBS_FINISH.  All uses changed.
4702         (STRING_FREE): Renamed from YY_OBS_FREE.  All uses changed.
4703
4704         * src/parse-gram.y (gram_error): loc is now const *.
4705         * src/reader.h (gram_error): Likewise.
4706
4707 2002-11-24  Paul Eggert  <eggert@twinsun.com>
4708
4709         Version 1.75c.
4710
4711         * tests/actions.at (Actions after errors): Use an output format
4712         more similar to that of the Printers and Destructors test.
4713         Test the position of the ';' token too.
4714         (Printers and Destructors): Likewise.
4715         (Printers and Destructors: %glr-parser): Remove for now, to avoid
4716         unnecessarily alarming people when the test fails.
4717
4718         * data/yacc.c (yyerrlab1): Move this label down, so that the
4719         parser does not discard the lookahead token if the user code
4720         invokes YYERROR.  This change is required for POSIX conformance.
4721
4722         * lib/error.c: Sync with gnulib.
4723
4724 2002-11-22  Paul Eggert  <eggert@twinsun.com>

4734 2002-11-20  Paul Eggert  <eggert@twinsun.com>
4735
4736         Avoid use of <assert.h>, as the GNU Coding Standards hint that one
4737         should use `if (! x) abort ();' rather than `assert (x);', and
4738         anyway it's one less thing to worry about configuring.
4739
4740         * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
4741         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
4742         and replace all instances of assert with abort.

4764

4766         (ARGMATCH_CONSTRAINT): New macro.
4767         (ARGMATCH_ASSERT): Use it.
4768
4769         * src/system.h (verify): New macro.
4770         * src/getargs.c (trace_argmatch, report_argmatch): Use verify
4771         rather than assert.
4772         * src/tables.c (tables_generate): Likewise.
4773
4774         * src/struniq.c (struniq_assert): Now returns void, and aborts
4775         if the assertion is false.
4776         (struniq_assert_p): Remove.
4777         * src/struniq.h: Likewise.
4778
4779 2002-11-18  Paul Eggert  <eggert@twinsun.com>
4780
4781         * data/glr.c (yygetLRActions): Replace `yyindex' with
4782         `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
4783         This fixes the regression with Sun ONE Studio 7 cc that I reported in
4784         <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
4785
4786 2002-11-18  Akim Demaille  <akim@epita.fr>
4787
4788         * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
4789         space.
4790         From Tim Van Holder.
4791
4792 2002-11-17  Paul Eggert  <eggert@twinsun.com>
4793
4794         Pacify Sun ONE Studio 7 lint.  Also, rename "ParseError"
4795         to "SyntaxError" for consistency with my 2002-11-15 change.
4796
4797         * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
4798         not define to {}, since this breaks the common use of `YYDPRINTF
4799         ((...));' if a single statement is desired (e.g. before `else').
4800         Work around GCC warnings by surrounding corresponding calls with
4801         {} if needed.
4802         (yyhasResolvedValue): Remove unused function.
4803         (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
4804         loop body.
4805         (yyreportSyntaxError): Renamed from yyreportParseError.
4806         (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
4807         All uses changed.
4808         * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
4809         extern when possible.  Remove unused initializations.
4810
4811 2002-11-16  Akim Demaille  <akim@epita.fr>
4812
4813         Augment the similarity between GLR and LALR traces.
4814
4815         * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
4816         (YY_REDUCE_PRINT): New.
4817         (yyparse): Use them.
4818         * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
4819         YYDPRINT here.
4820         (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
4821         state reached after the reduction/recovery, since...
4822         (yyparse, yyprocessOneStack): Report the state we are entering in.
4823
4824 2002-11-16  Akim Demaille  <akim@epita.fr>
4825
4826         * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
4827         Add support for --trace=skeleton.
4828         * src/scan-skel.l: %option debug.
4829         Scan strings of non-@ or \n instead of character by character.
4830         (scan_skel): Handle trace_skeleton.
4831         (QPUTS): New.
4832         (@output_parser_name@, @output_header_name@): ``Restore'' their
4833         support (used to be M4 macros).
4834         * data/yacc.c: Quote larger chunks, a la glr.c.
4835         * data/lalr1.cc: Likewise.
4836         The header guards are no longer available, so use some other
4837         string than `YYLSP_NEEDED'.
4838
4839 2002-11-16  Akim Demaille  <akim@epita.fr>
4840
4841         Make the ``Printers and Destructors'' test more verbose, taking
4842         `yacc.c''s behavior as (possibly wrong) reference.
4843
4844         * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
4845         instead of fprint on stdout.
4846         Set and report the last_line of the symbols.
4847         Consistently display values and locations.
4848
4849 2002-11-16  Paul Eggert  <eggert@twinsun.com>
4850
4851         * data/yacc.c: Avoid over-quoting of __line__ and __file__.
4852
4853 2002-11-15  Paul Eggert  <eggert@twinsun.com>
4854
4855         * tests/actions.at (Actions after errors): New test case.
4856
4857         * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
4858         src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
4859         tests/action.at, tests/calc.at, tests/conflicts.at,
4860         tests/cxx-type.at, tests/regression.at:
4861         "parse error" -> "syntax error" for POSIX compatibility.
4862         "parsing stack overflow..." -> "parser stack overflow" so
4863         that code matches Bison documentation.
4864
4865 2002-11-15  Akim Demaille  <akim@epita.fr>
4866
4867         * src/parse-gram.y (declaration): Have %parse-param and %lex-param
4868         take two BRACED_CODE, not two string_content.
4869         Free the scanner's obstack when we are done.
4870         (code_content): New.
4871         * tests/calc.at: Adjust.
4872         * doc/bison.texinfo: Adjust.
4873         Also, make sure to include the `,' for these declarations.
4874
4875 2002-11-15  Tim Van Holder  <tim.van.holder@pandora.be>
4876
4877         * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
4878         definition; avoids potential autoreconf problems.
4879
4880 2002-11-15  Akim Demaille  <akim@epita.fr>
4881
4882         Always check the value returned by yyparse.
4883
4884         * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
4885         returned by yyparse.
4886         (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
4887         Adjust calls.
4888         * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
4889         returned by yyparse.
4890
4891 2002-11-14  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
4892
4893         * data/glr.c (yyFail): Always set yyerrflag.  Corrects regression
4894         on input.at test.
4895
4896 2002-11-14  Paul Eggert  <eggert@twinsun.com>
4897
4898         * src/output.c (output_skeleton): Call xfopen instead of
4899         duplicating xfopen's body.
4900
4901         Fix bugs reported by Nelson H. F. Beebe in
4902         <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
4903
4904         * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
4905         "$CC -E foo.h" is allowed, as this doesn't work with the Portland
4906         Group compiler.  Instead, use "$CC -E bar.c".  Include the .h
4907         file twice in the grammar, as an extra check.
4908
4909         * tests/input.at (Torturing the Scanner): Surround the
4910         backslash-newline tests with "#if 0", to make it less likely that
4911         we'll run into compiler bugs.  Bring back solitary \ inside
4912         comment, but add a closing comment to work around HP C bug.  Don't
4913         test backslash-newline in C character constant.
4914
4915 2002-11-14  Akim Demaille  <akim@epita.fr>
4916
4917         * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
4918         status of the compiler.
4919         Calling `exit 1' is no longer needed.
4920         Reported by Nelson H. F. Beebe.
4921
4922 2002-11-14  Akim Demaille  <akim@epita.fr>
4923
4924         * tests/atlocal.in (CPPFLAGS): We have config.h.
4925         * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
4926         New.
4927         * tests/actions.at, tests/calc.at, tests/conflicts.at,
4928         * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
4929         * tests/regression.at, tests/torture.at: Use them for all the
4930         grammars that are to be compiled.
4931         * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
4932         * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
4933         * doc/bison.texinfo (GLR Parsers): Document `inline'.
4934
4935 2002-11-14  Akim Demaille  <akim@epita.fr>
4936
4937         * doc/bison.texinfo: Various formatting changes (alignments in
4938         samples, additional @group/@end group, GCS in samples.
4939         Use @deffn instead of simple @table to define the directives,
4940         macros, variables etc.
4941
4942 2002-11-13  Paul Eggert  <eggert@twinsun.com>
4943
4944         Fix some bugs reported by Albert Chin-A-Young in
4945         <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
4946
4947         * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
4948         -o c"; the HP C compiler chatters during compilation.
4949         Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
4950         * tests/headers.at (export YYLTYPE): Likewise.
4951
4952         * tests/input.at (Torturing the Scanner): Remove lines containing
4953         solitary backslashes, as they tickle a bug in the HP C compiler.
4954
4955         * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
4956         comments, since they're not portable.  Use GNU coding style.
4957
4958 2002-11-13  Akim Demaille  <akim@epita.fr>
4959
4960         * data/yacc.c: Leave bigger chunks of quoted text.
4961         (YYDSYMPRINTF): New.
4962         Use it to report symbol activities.
4963         * data/glr.c (YYDSYMPRINTF): New.
4964         Use it.
4965
4966 2002-11-12  Paul Eggert  <eggert@twinsun.com>
4967
4968         Version 1.75b.
4969
4970         * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
4971         (yyglrReduce): Return yyok, not 0.
4972         This should avoid the enumerated-type warnings reported
4973         by Nelson H. F. Beebe in
4974         <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
4975

4977         * lib/bitset.h [! BITSET_INLINE]: Remove.
4978         (bitset_set, bitset_reset, bitset_test): Rename local vars
4979         to avoid shadowing warnings by GCC.
4980
4981         * data/glr.c (inline): Remove #define.  It's the user's
4982         responsibility to #define it away, just like 'const'.
4983         This fixes one of the bugs reported by Nelson H. F. Beebe in
4984         <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
4985
4986         * Makefile.maint (po-check): Scan .l and .y files instead of the
4987         .c and the .h files that they generate.  This fixes the bug
4988         reported by Tim Van Holder in:
4989         <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
4990         Look for N_ as well as for _.  Try to avoid matching #define for
4991         N_ and _.
4992         * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
4993         src/system.h.  Add src/parse-gram.y, src/scan-gram.l.
4994         * src/scan-gram.l: Revamp regular expressions so that " and '
4995         do not confuse xgettext.
4996
4997         * src/struniq.h (struniq_new): Do not declare the return type
4998         to be 'const'; this violates the C standard.
4999         * src/struniq.c (struniq_new): Likewise.
5000
5001 2002-11-12  Albert Chin-A-Young <china@thewrittenword.com>
5002
5003         * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
5004         duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
5005         linker.
5006
5007 2002-11-12  Akim Demaille  <akim@epita.fr>

5027
5028         * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
5029         Use it to test the GLR parser.
5030
5031 2002-11-12  Akim Demaille  <akim@epita.fr>
5032
5033         * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
5034         defines it.
5035         * data/glr.c (yystos): New.
5036         (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
5037         (YYDSYMPRINT): New.
5038         (yyval): Don't define it, it is handled via M4.
5039         (yyrecoverParseError): Free verbosely the discarded symbols.
5040         * data/yacc.c (yysymprint): Remove, rather...
5041         (b4_yysymprint_generate): invoke.
5042         * data/c.m4 (b4_yysymprint_generate): New.
5043         Accept pointers as arguments, as opposed to the version from
5044         yacc.c.
5045         (b4_yydestruct_generate): Likewise.
5046         * tests/cations.at (Printers and Destructors): Use Bison directives
5047         instead of CPP macros.
5048         Don't rely on internal details.
5049
5050 2002-11-12  Akim Demaille  <akim@epita.fr>
5051
5052         * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
5053         * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
5054         Don't work on yychar (i.e., do set it to YYEMPTY, don't match
5055         it against YYEMPTY and so forth), work on yytoken (i.e., set
5056         it to YYEMPTY etc.).
5057         (yydestruct): Replace with a b4_yydestruct_generate invocation.
5058         (b4_symbol_actions): Remove.
5059         * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
5060         for 0, end-of-input.
5061
5062 2002-11-12  Akim Demaille  <akim@epita.fr>

5069         cannot be NULL, not XFREE.
5070         (pack_vector): Use assert, not fatal, for bound violations.
5071         * src/state.c (state_new): Likewise.

5078
5079         * src/scan-gram.l, src/reader.h (scanner_last_string_free):
5080         Restore.
5081         * src/scan-gram.l (last_string): Is global to the file, not to
5082         yylex.
5083         * src/parse-gram.y (input): Don't append the epilogue here,
5084         (epilogue.opt): do it here, and free the scanner's obstack.
5085         * src/reader.c (epilogue_set): Rename as...
5086         (epilogue_augment): this.
5087         * data/c.m4 (b4_epilogue): Defaults to empty.

5127         * src/complain.h, src/complain.c: Likewise.
5128         * src/main.c (main): Call struniqs_new early enough to use it for
5129         file names.
5130         Don't free the input file name.
5131
5132 2002-11-12  Akim Demaille  <akim@epita.fr>
5133
5134         * src/symtab.c (symbol_free): Remove dead deactivated code:
5135         type_name are properly removed.
5136         Don't use XFREE to free items that cannot be NULL.

5145 2002-11-11  Paul Eggert  <eggert@twinsun.com>
5146
5147         Revamp to fix many (but not all) of the C- and M4-related quoting
5148         problems.  Among other things, this fixes the Bison bug reported
5149         by Jan Hubicka when processing the Bash grammar; see:
5150         <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
5151
5152         Use new @ escapes consistently.  Represent brackets with @{ and @}
5153         rather than @<:@ and @:>@, since this works a bit better with dumb
5154         editors like vi.  Represent @ with @@, since @ is now consistently
5155         an escape.  Use @oline@ and @ofile@ rather than __oline__ and
5156         __ofile__, to avoid unexpected expansions.  Similarly, use @output
5157         rather than #output.
5158
5159         * data/c.m4 (b4_copyright): Omit file name from comment, since
5160         the file name could contain "*/".
5161         (b4_synclines_flag): Don't quote the 2nd argument; it should already
5162         be quoted.  All uses changed.
5163
5164         * data/glr.c: Use new @ escapes consistently.
5165         (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
5166         b4_output_header_suffix, b4_output_header_name, b4_header_guard):
5167         Remove, since they couldn't handle arbitrary characters in file
5168         names.
5169         * data/lalr1.cc: Likewise.
5170         * data/yacc.c: Likewise.
5171
5172         * src/files.c (output_infix): Remove; all uses removed.
5173         * src/files.h: Likewise.
5174
5175         * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
5176         mishandled funny characters in file names, and anyway it isn't
5177         needed any more.
5178         * data/yacc.c: Likewise.
5179         * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
5180
5181         * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
5182         * data/yacc.c: Likewise.
5183
5184         * src/muscle_tab.c: Include quotearg.h, since we need to quote C
5185         strings now.
5186         (muscle_init): Quote filename as a C string.
5187         * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
5188         (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
5189         * src/output.c (escaped_file_name_output): New function.
5190         (prepare_symbols): Quote tokens for M4.
5191         (prepare): Don't insert output_infix, output_prefix,
5192         output_parser_name, output_header_name; this is now down by scan-skel.
5193         Insert skeleton as a C string.
5194
5195         * src/output.c (user_actions_output, symbol_destructors_output,
5196         symbol_printers_output): Quote filenames for C and M4.
5197         * src/reader.c (prologue_augment, epilogue_set): Likewise.
5198
5199         * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
5200         escapes other than \\ and \'; this simplifies the code.
5201         (<SC_STRING>): Likewise, for \\ and \".
5202         (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
5203         SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
5204         Use new escapes @{ and @} for [ and ].
5205
5206         * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
5207         them with auto vars.
5208         Switch to new escape scheme, where @ is the escape character uniformly.
5209         Abort if a stray escape character is found.  Avoid unbounded input
5210         buffer when parsing non-escaped text.
5211
5212         * tests/input.at (Torturing the Scanner): Add tests that @oline@,
5213         __oline__, #output, $@, and @{ do not have unintended meanings.
5214
5215 2002-11-09  Paul Eggert  <eggert@twinsun.com>
5216
5217         Fix the test failure due to GCC warnings described in
5218         <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
5219         * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
5220         evaluate to 0 if it's impossible for NINF to be in the respective
5221         table.
5222         (yygetLRActions, yyrecoverParseError): Use them.
5223
5224         * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
5225         counted in the token inserted at end of file.  Now takes
5226         location_t *, not location_t, so that the location can be
5227         adjusted.  All uses changed.
5228
5229         * tests/regression.at (Invalid inputs): Adjust wording in
5230         diagnostic to match the new behavior.
5231
5232         * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
5233         AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
5234         AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
5235         abort ();'.  This reduces the runtime of the "Many lookaheads"
5236         test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
5237         GCC 3.2.
5238
5239 2002-11-07  Paul Eggert  <eggert@twinsun.com>
5240
5241         * src/parse-gram.y (CHARACTER): Remove unused token.
5242         All uses removed.
5243
5244         * src/scan-gram.l: Remove stack option.  We no longer use the
5245         stack, since the stack was never deeper than 1; instead, use the
5246         new auto var c_context to record the stacked value.
5247
5248         Remove nounput option.  At an unexpected end of file, we now unput
5249         the minimal input necessary to end cleanly; this simplifies the
5250         code.
5251
5252         Avoid unbounded token sizes where this is easy.
5253
5254         (unexpected_end_of_file): New function.
5255         Use it to systematize the error message on unexpected EOF.
5256         (last-string): Now auto, not static.
5257         (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
5258         (scanner_last_string_free): Remove; not used.
5259         (percent_percent_count): Move decl to just before use.
5260         (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
5261         not the (never otherwised-used) CHARACTER.
5262
5263 2002-11-07  Akim Demaille  <akim@epita.fr>
5264
5265         Let yyerror always receive the msg as last argument, so that
5266         yyerror can be variadic.
5267
5268         * data/yacc.c (b4_yyerror_args): New.
5269         Use it when calling yyerror.
5270         * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
5271         Use it when calling yyerror.
5272         * doc/bison.texinfo (Error Reporting): Adjust.
5273         * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
5274         * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
5275
5276 2002-11-06  Akim Demaille  <akim@epita.fr>
5277
5278         #line should have quoted strings.
5279         Ideally, this should be done by m4_quotearg.
5280
5281         * src/scan-skel.l: Include quotearg.h.
5282         Quote __ofile__.
5283         * src/output.c (symbol_printers_output)
5284         (symbol_destructors_output): Quote the file name.
5285
5286 2002-11-06  Akim Demaille  <akim@epita.fr>

5293         Restore --no-lines.
5294         Reported by Jim Kent.
5295
5296         * data/c.m4 (b4_syncline): New.
5297         * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
5298         * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
5299         * src/output.c (user_actions_output): Likewise.
5300         (prepare): Define 'b4_synclines_flag'.
5301         * src/muscle_tab.c (muscle_init): Don't define b4_linef.
5302
5303 2002-11-06  Akim Demaille  <akim@epita.fr>
5304
5305         * src/main.c (main): Free `infile'.
5306         * src/scan-gram.l (handle_syncline): New.
5307         Recognize `#line'.
5308         * src/output.c (user_actions_output, symbol_destructors_output)
5309         (symbol_printers_output): Use the location's file name, not
5310         infile.
5311         * src/reader.c (prologue_augment, epilogue_set): Likewise.
5312
5313 2002-11-05  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
5314
5315         * src/tables.c (matching_state): Don't allow states to match if
5316         either has GLR conflict entries.
5317
5318 2002-11-05  Paul Eggert  <eggert@twinsun.com>
5319
5320         * src/scan-gram.l: Use more accurate diagnostics, e.g.
5321         "integer out of range" rather than "invalid value".
5322         * tests/input.at (Invalid $n, Invalid @n): Change expected wording
5323         accordingly.
5324
5325         Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
5326         Also, remove one static variable in the scanner.
5327
5328         * src/scan-gram.l (braces_level): Now auto, not static.
5329         Initialize to zero if the compiler is being picky.
5330         (INITIAL): Clear braces_level instead of incrementing it.
5331         (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
5332         as POSIX 1003.1-2001 requires.
5333         * src/system.h (IF_LINT): New macro, taken from coreutils.
5334         * configure.ac: Define "lint" if --enable-gcc-warnings.
5335
5336 2002-11-05  Akim Demaille  <akim@epita.fr>
5337
5338         * src/scan-gram.l: When it starts with `%', complain about the
5339         whole directive, not just that `invalid character: %'.
5340
5341 2002-11-04  Akim Demaille  <akim@epita.fr>
5342
5343         * Makefile.maint: Update from Autoconf.

5346 2002-11-04  Akim Demaille  <akim@epita.fr>
5347
5348         * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
5349         and yyerror.
5350         Have yyerror `use' its arguments.
5351         * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
5352         returns true when location & yacc & pure & parse-param.
5353         (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
5354
5355 2002-11-04  Akim Demaille  <akim@epita.fr>
5356
5357         * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
5358         clashes.
5359         * src/scan-gram.l: Use [\'] instead of ['] to pacify
5360         font-lock-mode.
5361         Use complain_at.
5362         Use quote, not quote_n since LOCATION_PRINT no longer uses the
5363         slot 0.
5364
5365 2002-11-03  Paul Eggert  <eggert@twinsun.com>
5366
5367         * src/reader.c (get_merge_function, grammar_current_rule_check):
5368         Use consistent diagnostics for reporting type name clashes.
5369         Quote the types with <>, for consistency with Yacc.
5370         * tests/input.at (Type Clashes): Adjust to diagnostic changes.
5371
5372 2002-11-03  Akim Demaille  <akim@epita.fr>
5373
5374         * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
5375         New.

5377         (b4_parse_param): Remove.
5378         Use b4_identification.
5379         Propagate b4_pure_args where needed to pass them to yyerror.

5386         (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
5387         (yyreportAmbiguity): When using a pure parser, also need
5388         the location, and the parse-params.
5389         Adjust callers.
5390         (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
5391         When using a pure parser, also need the parse-params.
5392         Adjust callers.

5394         (%pure-parser + %parse-param) LALR and GLR parsers.
5395         (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
5396         AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
5397         AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
5398         (_AT_DATA_CALC_Y): Equip for purity of yyerror.
5399         (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
5400         * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
5401         * doc/bison.texinfo: Untabify the whole file.
5402         (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.

5404         (Error Reporting): Adjust to these new directives.
5405         Document %error-verbose, deprecate YYERROR_VERBOSE.
5406
5407 2002-11-03  Akim Demaille  <akim@epita.fr>
5408
5409         * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
5410         AT_CHECK_CALC_GLR invocations to use % directives, instead of
5411         command line options.
5412         * tests/cxx-type.at: Formatting changes.
5413
5414 2002-11-03  Paul Eggert  <eggert@twinsun.com>
5415
5416         * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
5417         to count columns correctly, and to check for invalid inputs.
5418
5419         Use mbsnwidth to count columns correctly.  Account for tabs, too.
5420         Include mbswidth.h.
5421         (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
5422         (extend_location): New function.
5423         (YY_LINES): Remove.
5424
5425         Handle CRLF in C code rather than in Lex code.
5426         (YY_INPUT): New macro.
5427         (no_cr_read): New function.
5428
5429         Scan UCNs, even though we don't fully handle them yet.
5430         (convert_ucn_to_byte): New function.
5431
5432         Handle backslash-newline correctly in C code.
5433         (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
5434         (eols, blanks): Remove.  YY_USER_ACTION now counts newlines etc.;
5435         all uses changed.
5436         (tag, splice): New EREs.  Do not allow NUL or newline in tags.
5437         Use {splice} wherever C allows backslash-newline.
5438         YY_STEP after space, newline, vertical-tab.
5439         ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
5440
5441         (letter, id): Don't assume ASCII; e.g., spell out a-z.
5442
5443         ({int}, handle_action_dollar, handle_action_at): Check for integer
5444         overflow.
5445
5446         (YY_STEP): Omit trailing semicolon, so that it's more like C.
5447
5448         (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
5449         as well as \000.  Check for UCHAR_MAX, not 255.
5450         Allow \x with an arbitrary positive number of digits, as in C.
5451         Check for overflow here.
5452         Allow \? and UCNs, for compatibility with C.
5453
5454         (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
5455         with quote slot used by complain_at.
5456
5457         * tests/input.at: Add tests for backslash-newline, m4 quotes
5458         in symbols, long literals, and funny escapes in strings.
5459
5460         * configure.ac (jm_PREREQ_MBSWIDTH): Add.
5461         * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
5462         * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
5463         * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
5464         * m4/mbswidth.m4: New file, from GNU coreutils.
5465
5466         * doc/bison.texinfo (Grammar Outline): Document // comments.
5467         (Symbols): Document that trigraphs have no special meaning in Bison,
5468         nor is backslash-newline allowed.
5469         (Actions): Document that trigraphs have no special meaning.
5470
5471         * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
5472         no longer used.
5473
5474 2002-11-02  Paul Eggert  <eggert@twinsun.com>
5475
5476         * src/reader.c: Don't include quote.h; not needed.
5477         (get_merge_function): Reword warning to be consistent with
5478         type clash diagnostic in grammar_current_rule_check.
5479
5480         * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
5481         bug in trigraph handling.
5482
5483         * src/output.c (prepare_symbols): When printing token names,
5484         escape "[" as "@<:@" and likewise for "]".
5485
5486         * src/system.h (errno): Remove declaration, as we are now
5487         assuming C89 or better, and C89 guarantees errno.
5488
5489 2002-10-30  Paul Eggert  <eggert@twinsun.com>
5490
5491         * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
5492         Check for close failures.
5493         * src/files.h (xfclose): Return void, not int, since it always
5494         returned zero.
5495         * src/files.c (xfclose): Likewise.  Report I/O error if ferror
5496         indicates one.
5497         * src/output.c (output_skeleton): Use xfclose rather than fclose
5498         and ferror.  xfclose now checks ferror.
5499
5500         * data/glr.c (YYLEFTMOST_STATE): Remove.
5501         (yyreportTree): Use a stack-based leftmost state.  This avoids
5502         our continuing battles with bogus warnings about initializers.
5503
5504 2002-10-30  Akim Demaille  <akim@epita.fr>
5505
5506         * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
5507         #if.
5508
5509 2002-10-29  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
5510
5511         * tests/glr-regr1.at: New test for reported regressions.
5512         * tests/testsuite.at: Add glr-regr1.at test.
5513         * tests/Makefile.am: Add glr-regr1.at test.
5514
5515 2002-10-24  Paul Eggert  <eggert@twinsun.com>
5516
5517         Version 1.75a.
5518
5519         * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
5520         * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
5521         we use malloc.  Don't assume 'A' through 'Z' are contiguous.
5522         Don't assume strdup exists; POSIX says its an XSI extension.
5523         Check for buffer overflow on input.
5524
5525 2002-10-24  Akim Demaille  <akim@epita.fr>
5526
5527         * src/output.c (output_skeleton): Don't disable M4sugar comments
5528         too soon: it results in comments being expanded.
5529         * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
5530         first output.
5531
5532 2002-10-24  Akim Demaille  <akim@epita.fr>
5533
5534         * data/yacc.c (m4_int_type): New.
5535         * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
5536         char' as only yacc.c wants K&R portability.
5537         * data/glr.c (yysigned_char): Remove.
5538         * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
5539         Reported by Quoc Peyrot.
5540
5541 2002-10-23  Paul Eggert  <eggert@twinsun.com>
5542
5543         * src/main.c (main): With --trace=time, report times even if a
5544         non-fatal error occurs.  Formerly, the times were reported in some
5545         such cases but not in others.
5546         * src/reader.c (reader): Just return if a complaint has been issued,
5547         instead of exiting, so that 'main' can report times.
5548
5549 2002-10-22  Akim Demaille  <akim@epita.fr>
5550
5551         * src/system.h: Include sys/types.
5552         Reported by Bert Deknuydt.
5553
5554 2002-10-23  Paul Eggert  <eggert@twinsun.com>
5555
5556         * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
5557         Suggested by Art Haas.
5558
5559 2002-10-22  Paul Eggert  <eggert@twinsun.com>
5560
5561         * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
5562         decl; not needed any more.
5563         * src/main.c (main): Use return to exit, undoing yesterday's change.
5564         The last OS that we could find where this wouldn't work is
5565         SunOS 3.5, and that's too old to worry about now.
5566
5567         * data/glr.c (struct yyltype): Define members even when not
5568         doing locations.  This is more consistent with yacc.c, and it
5569         works around the following bug reports:
5570         http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
5571         http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
5572
5573         * doc/bison.texinfo: Minor spelling and typographical fixes.  Use
5574         @acronym consistently.  Standardize on "Yacc" instead of "YACC",
5575         "Algol" instead of "ALGOL".  Give a bit more history about BNF.
5576
5577 2002-10-22  Akim Demaille  <akim@epita.fr>
5578
5579         * data/README: New.
5580
5581 2002-10-21  Paul Eggert  <eggert@twinsun.com>
5582
5583         Be consistent about 'bool'; the old code used an enum in one
5584         module and an int in another, and this violates the C standard.
5585         * m4/stdbool.m4: New file, from coreutils 4.5.3.
5586         * configure.ac (AC_HEADER_STDBOOL): Add.
5587         * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
5588         * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
5589         * src/symtab.c (hash_compare_symbol_t): Likewise.
5590         * src/system.h (bool, false, true): Use a definition consistent
5591         with ../lib/hash.c.  All uses changed.
5592
5593         * src/complain.c (warning_issued): Renamed from warn_message_count,
5594         so that we needn't worry about integer overflow (!).
5595         Now of type bool.  All uses changed.
5596         (complaint_issued): Renamed from complain_message_count; likewise.
5597
5598         * src/main.c (main): Use exit to exit with failure.
5599
5600         * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
5601         rather than 1 and 0.
5602         * src/main.c (main): Likewise.
5603         * src/getargs.c (getargs): Likewise.
5604         * src/reader.c (reader): Likewise.
5605
5606         * src/getarg.c (getargs): Remove duplicate code for
5607         "Try `bison --help'".
5608
5609         * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
5610         What was that "2" for?
5611
5612         * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
5613         * src/getargs.c (usage): Likewise.
5614
5615         * src/getargs.c (getargs): When there are too few operands, report
5616         the last one.  When there are too many, report the first extra
5617         one.  This is how diffutils does it.
5618
5619 2002-10-20  Paul Eggert  <eggert@twinsun.com>
5620
5621         Remove K&R vestiges.
5622         * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
5623         * src/complain.c (VA_START): Remove.  Assume prototypes.
5624         (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
5625         (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
5626         fatal): Assume prototypes.
5627         * src/complain.h: Assume prototypes.
5628         * src/system.h (PARAMS): Remove.
5629         Include <limits.h> unconditionally, since it's guaranteeed even
5630         for a freestanding C89 compiler.
5631         (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
5632         * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
5633
5634 2002-10-20  Akim Demaille  <akim@epita.fr>
5635
5636         * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
5637         * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
5638         (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
5639         (yyresolveStates, yyresolveAction, yyresolveStack)
5640         (yyprocessOneStack): Use them.
5641         (yy_reduce_print): New.
5642         * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
5643
5644 2002-10-20  Akim Demaille  <akim@epita.fr>
5645
5646         * data/c.m4 (b4_c_ansi_args): Recognize functions with no
5647         arguments and output `void'.
5648         (b4_c_function): Rename as...
5649         (b4_c_function_def): this.
5650         (b4_c_function_decl, b4_c_ansi_function_def)
5651         (b4_c_ansi_function_decl): New.
5652         Change the interpretation of the arguments: before `int, foo', now
5653         `int foo, foo'.
5654         * data/yacc.c (yyparse): Prototype and define thanks to these.
5655         Adjust b4_c_function_def uses.
5656         * data/glr.c (yyparse): Likewise, but ANSI only.
5657
5658 2002-10-20  Akim Demaille  <akim@epita.fr>
5659
5660         * src/output.c (prepare): Move the definition of `tokens_number',
5661         `nterms_number', `undef_token_number', `user_token_number_max'
5662         to...
5663         (prepare_tokens): Here.
5664         (prepare_tokens): Rename as...
5665         (prepare_symbols): this.
5666         (prepare): Move the definition of `rules_number' to...
5667         (prepare_rules): here.
5668         (prepare): Move the definition of `last', `final_state_number',
5669         `states_number' to...
5670         (prepare_states): here.
5671         * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
5672
5673 2002-10-20  Akim Demaille  <akim@epita.fr>
5674
5675         * src/tables.h, src/tables.c, src/output.c: Comment changes.
5676
5677 2002-10-20  Akim Demaille  <akim@epita.fr>
5678
5679         * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
5680         * data/c.m4: here.
5681
5682 2002-10-20  Akim Demaille  <akim@epita.fr>
5683
5684         * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
5685         * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
5686         `pair'.
5687         (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
5688         `name' to...
5689         * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
5690         (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
5691         These.
5692
5693 2002-10-19  Paul Eggert  <eggert@twinsun.com>
5694
5695         Do not create a temporary file, as that involves security and
5696         cleanup headaches.  Instead, use a pair of pipes.
5697         Derived from a suggestion by Florian Krohm.
5698         * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
5699         * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
5700         * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
5701         (BISON_PREREQ_SUBPIPE): Add.
5702         * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
5703         Add subpipe.h, subpipe.c.
5704         * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4.  Add subpipe.m4.
5705         * po/POTFILES.in: Add lib/subpipe.c.
5706         * src/output.c: Include "subpipe.h".
5707         (m4_invoke): Remove decl.
5708         (scan_skel): New decl.
5709         (output_skeleton): Use pipe rather than temporary file for m4 input.
5710         Check that m4sugar.m4 is readable, to avoid deadlock.
5711         Check for pipe I/O error.
5712         * src/scan-skel.l (readpipe): Remove decl.
5713         (scan_skel): New function, to be used in place of m4_invoke.
5714         Read from stream rather than file.
5715
5716         * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
5717         float, as this generates a warning on Solaris 8 + GCC 3.2 with
5718         --enable-gcc-warnings.  Instead, divide into 1.0 rather than 1;
5719         this generates a more-accurate value anyway.
5720
5721         * lib/timevar.c (timervar_accumulate): Rename locals to
5722         avoid confusion with similarly-named more-global.
5723         * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
5724
5725         * src/output.c (prepare): Use xstrdup to convert char const *
5726         to char *, to avoid GCC warning.
5727
5728 2002-10-19  Akim Demaille  <akim@epita.fr>
5729
5730         * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
5731         LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
5732         Use them to have `calc.y' ready for %pure-parser.
5733         * data/yacc.c (YYLEX): Pass a yylex return type to
5734         b4_c_function_call.
5735
5736 2002-10-19  Akim Demaille  <akim@epita.fr>
5737
5738         Prototype support of %lex-param and %parse-param.
5739
5740         * src/parse-gram.y: Add the definition of the %lex-param and
5741         %parse-param tokens, plus their rules.
5742         Drop the `_' version of %glr-parser.
5743         Add the "," token.

5749         Adjust all dependencies.
5750         * src/muscle_tab.c (muscle_init): Adjust: use
5751         MUSCLE_INSERT_STRING.

5765         (usage, version): Don't take a FILE * as arg, it is pointless.
5766         (getargs): When there is an incorrect number of arguments, make it
5767         an error, and report it GNUlically thanks to `usage ()'.

5770
5771         * data/glr.c (yyreportParseError): Don't assume that sprintf
5772         yields the length of the printed string, as this is not true
5773         on SunOS 4.1.4.  Reported by Peter Klein.

5787         (reader): Use trace_flag to enable scanner/parser debugging,

5806         Stop using the "enum_" trick for K&R-style function definitions;
5807         it confused me, and I was the author!  Instead, assume that people
5808         who want to use K&R C compilers (when using these modules in GCC,
5809         perhaps?) will run ansi2knr.

5941         Let nondeterministic skeletons be usable with deterministic
5942         tables.
5943
5944         With the patch, GAWK compiled by GCC without -O2 passes its test
5945         suite using a GLR parser driven by LALR tables.  It fails with -O2
5946         because `struct stat' gives two different answers on my machine:
5947         88 (definition of an auto var) and later 96 (memset on this var).
5948         Hence the stack is badly corrumpted.  The headers inclusion is to
5949         blame: if I move the awk.h inclusion before GLR's system header
5950         inclusion, the two struct stat have the same size.
5951

5990         (which was a bug: it should have been YYTABEL_NINF, and yet it was
5991         not satisfying as we could compare an YYACTION computed from
5992         YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the

6003         <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
6004         "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
6005         because the Bison parser reads the second action before reducing
6006         the first one.
6007         * src/scan-gram.l (rule_length): New static var.
6008         Use it to keep track of the rule length in the scanner, since
6009         we can't expect the parser to be in lock-step sync with the scanner.

6037         Output token definitions before the first part of user declarations.
6038         Fixes compatibility problem reported by Jim Gifford for kbd in

6043         * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
6044         (yyparse): here.  This undoes some of the 2002-07-25 change.

6060
6061         Portability fixes for bitsets; this also avoids several GCC
6062         warnings.
6063
6064         * lib/abitset.c: Include <stddef.h>, for offsetof.
6065         * lib/lbitset.c: Likewise.
6066
6067         * lib/abitset.c (abitset_bytes): Return a size that is aligned
6068         properly for vectors of objects.  Do not assume that adding a
6069         header size to a multiple of a word size yields a value that is
6070         properly aligned for the whole union.
6071         * lib/bitsetv.c (bitsetv_alloc): Likewise.
6072
6073         * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
6074         unique names for structures.
6075         * lib/ebitset.c (ebitset_bytes): Likewise.
6076         * lib/lbitset.c (lbitset_bytes): Likewise.
6077
6078         * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
6079         abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
6080         abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
6081         abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
6082         abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
6083         abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
6084         abitset_or_and_cmp, abitset_copy): Supply prototype decls,
6085         to improve the type-checking that GCC can do.
6086         * lib/bitset.c (bitset_op4_cmp): Likewise.
6087         * lib/bitset_stats.c (bitset_stats_count,
6088         bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
6089         bitset_stats_copy, bitset_stats_disjoint_p,
6090         bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
6091         bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
6092         bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
6093         bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
6094         bitset_stats_and_or_cmp, bitset_stats_andn_or,
6095         bitset_stats_andn_or_cmp, bitset_stats_or_and,
6096         bitset_stats_or_and_cmp): Likewise.
6097         * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
6098         lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
6099         lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
6100         lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
6101
6102         * lib/abitset.h: Include bitset.h, not bbitset.h.
6103         * lib/ebitset.h: Likewise.
6104         * lib/lbitset.h: Likewise.
6105
6106         * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
6107         All instances of parameters of type enum bitset_opts are now of
6108         type enum_bitset_opts, to conform to the C Standard, and similarly
6109         for enum_bitset_type.
6110         * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
6111         * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
6112
6113         Do not use "struct bitset_struct" to mean different things in
6114         different modules.  Not only is this confusing, it violates
6115         the C Standard, which requires that structure types in different
6116         modules must be compatible if one is to be passed to the other.
6117         * lib/bbitset.h (bitset): Now points to a union, not to a struct.
6118         All instances of "struct bitset_struct *" replaced with "bitset".
6119         * lib/bitset.h (struct bitset_struct): Remove, replacing with....
6120         (union bitset_union, struct abitset_struct, struct ebitset_struct,
6121         struct lbitset_struct, struct bitset_stats_struct): New types.
6122         All uses of struct bitset_struct changed to union bitset_union,
6123         etc.
6124         * lib/abitset.c (struct abitset_struct, abitset,
6125         struct bitset_struct): Remove.
6126         * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
6127         struct bitset_struct): Remove.
6128         * lib/ebitset.c (struct ebitset_struct, ebitset, struct
6129         bitset_struct): Remove.
6130         * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
6131         Likewise.
6132
6133         Do not call a function of type T using a call that assumes the
6134         function is of a different type U.  Standard C requires that a
6135         function must be called with a type that is compatible with its
6136         definition.
6137         * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
6138         New decls.
6139         * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
6140         New functions.
6141         * lib/ebitset.c (PFV): Remove.
6142         * lib/lbitset.c (PFV): Likewise.
6143         * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
6144         ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
6145         decls.
6146         (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
6147         (ebitset_vtable): Use them.
6148         * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
6149         lbitset_xor): New functions.
6150         (lbitset_vtable): Use them.
6151
6152         * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
6153         Declare.
6154
6155         * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
6156         GCC warning.
6157         * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
6158         Use offsetof, for simplicity.
6159
6160 2002-10-06  Paul Eggert  <eggert@twinsun.com>
6161
6162         * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
6163         the same width as int.  This reapplies a hunk of the 2002-08-12 patch
6164         <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
6165         which was inadvertently undone by the 2002-09-30 patch.
6166         * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
6167         the same width as int.
6168
6169 2002-10-04  Paul Eggert  <eggert@twinsun.com>
6170
6171         Version 1.50.
6172
6173         * configure.ac (AC_INIT), NEWS: Increment version number.
6174
6175         * doc/bison.texinfo: Minor spelling, grammar, and white space
6176         fixes.
6177         (Symbols): Mention that any negative value returned from yylex
6178         signifies end-of-input.  Warn about negative chars.  Mention
6179         the portable Standard C character set.
6180
6181         The GNU coding standard says CFLAGS and YFLAGS are reserved
6182         for the installer to set.
6183         * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
6184         * src/Makefile.am (AM_CFLAGS): Likewise.
6185         (AM_YFLAGS): Renamed from YFLAGS.
6186
6187         Fix some MAX and MIN problems.
6188         * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
6189         * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
6190         * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
6191         * src/reader.c (reader): Use it.
6192
6193         * tests/regression.at (Braces parsing): Use grep, not fgrep, as
6194         POSIX 1003.1-2001 has removed fgrep.

6196 2002-10-04  Michael Hayes  <m.hayes@elec.canterbury.ac.nz>
6197
6198         * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
6199         interpreted as signed.
6200         * lib/ebitset.c (ebitset_list): Fix bug.
6201

6204         More fixes for 64-bit hosts and large bitsets.

6220         * lib/bitsetv.c (bitsetv_alloc, bitsetv_create, bitsetv_free,

6265         * lib/bbitset.h (BITSET_BINDEX_MAX, BITSET_WINDEX_MAX,
6266         BITSET_SIZE_MAX): New macros.
6267         (BITSET_INDEX_MAX): Remove.  It wasn't right, since it assumed that
6268         sizeof (bitset_word) == sizeof (bitset_windex).  All uses changed
6269         to BITSET_WINDEX_MAX.
6270
6271         * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
6272         bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

6372
6373         * doc/bison.texinfo (Conditions): Make explicit that the GPL

6386
6387 2002-09-04  Jim Meyering  <jim@meyering.net>
6388
6389         * data/yacc.c: Guard the declaration of yytoknum also with
6390         `#ifdef YYPRINT', so it is declared only when used.
6391

6393
6394         * configure.in: Rename as...

6409         (DISTCLEANFILES): Remove.
6410         * NEWS: Mention that GNU M4 is now required.  Clarify what is

6412         * configure.in (AC_CHECK_DECLS): Add getenv, getopt.
6413         (AM_GNU_GETTEXT_VERSION): New macro, replacing GETTEXT_VERSION var.

6422         (yyreportParseError): Use size_t for yysize.
6423         (yy_yypstack): No longer nested inside yypstates, as nested
6424         functions are not portable.  Do not assume size_t is the
6425         same width as int.
6426         (yypstates): Do not assume that ptrdiff_t is the same width
6427         as int, and similarly for yyposn and YYINDEX.
6428
6429         * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
6430
6431         * lib/Makefile.am (INCLUDES): Do not include from the intl
6432         directory, which has been removed.

6441
6442         * lib/abitset.c (abitset_reverse_list, ebitset_reverse_list):
6443         Do not assume that bitset_windex is the same width as unsigned.
6444

6452
6453         * lib/abitset.c (abitset_op1): Use -1, not ~0, as memset arg (for
6454         portability to one's complement hosts!).
6455         * lib/ebitset.c (ebitset_op1): Likewise.
6456         * lib/lbitset.c (lbitset_op1): Likewise.
6457

6460         lib/hash.c, lib/hash.h, lib/strnlen.c, lib/xmalloc.c:
6461         Sync with fileutils.
6462         * lib/error.c, lib/getopt.c, lib/getopt.h, lib/getopt1.c,
6463         lib/gettext.h: Sync with diffutils.

6466         lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
6467
6468         * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
6469         PROTOTYPES to check for prototypes, and "defined __STDC__" to
6470         check for void *.
6471
6472         * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
6473         size_t; the old version tried to do this but casted improperly.
6474         (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
6475         (bitset_test): Now returns int, not unsigned long.
6476
6477         * lib/bitset_stats.c: Include "gettext.h".
6478         (_): New macro.
6479         (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
6480         name locals "index", as it generates unnecessary warnings on some
6481         hosts that have an "index" function.
6482
6483         * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
6484         bitset_stats_read, bitset_stats_write): Wrap strings in _() if
6485         they need translation.

6496
6497         * m4/Makefile.am (EXTRA_DIST): Remove codeset.m4,
6498         glibc21.m4, isc-posix.m4 lcmessage.m4, stage.m4.
6499         * m4/malloc.m4, m4/realloc.m4: Sync with diffutils.
6500         * m4/mbstate_t.m4: Sync with fileutils.
6501         * m4/prereq.m4 (jm_PREREQ_QUOTEARG): AC_MBSTATE_T -> AC_TYPE_MBSTATE_T.
6502
6503         * po/LINGUAS: Add pt_BR.
6504         * po/POTFILES.in: Add src/assoc.c, src/closure.c, src/gram.c,
6505         src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
6506         lib/timevar.c.
6507         Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
6508         manual recommends.
6509         Similarly, use src/scan-gram.l instead of src/scan-gram.c.
6510
6511         * src/complain.c (strerror_r): Remove decl; not needed.
6512         (strerror): Use same pattern as ../lib/error.c.
6513
6514         * src/files.c, src/files.h (compute_header_macro): Remove; unused.
6515
6516         * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
6517
6518         * src/main.c (main): Cast result of bindtextdomain and textdomain
6519         to void, to avoid a GCC warning when --disable-nls is in effect.
6520
6521         * src/scan-gram.l: Use strings rather than escapes when possible,
6522         to minimize the number of warnings from xgettext.
6523         (handle_action_dollar, handle_action_at): Don't use isdigit,
6524         as it mishandles negative chars and it may not work as expected
6525         outside the C locale.
6526
6527         * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
6528         this is a GCC extension and is not portable to other compilers.
6529
6530         * src/system.h (alloca): Use same pattern as ../lib/error.c.
6531         Do not include <ctype.h>; no longer needed.
6532         Do not include <malloc.h>; no longer needed (and generates
6533         warnings on OpenBSD 3.0).
6534
6535         * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
6536         it's not portable.
6537
6538         * tests/regression.at: Do not use 'cc -c input.c -o input';
6539         Sun C rejects this.  Instead, use 'cc -c input.c -o input.o'.
6540
6541         * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
6542         exit status as failure, not just exit status 1.  Sun C exits
6543         with status 2 sometimes.
6544
6545         * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
6546         Use it for the two large tests.
6547
6548 2002-08-02  Akim Demaille  <akim@epita.fr>
6549
6550         * src/conflicts.c (conflicts_output): Don't output rules never
6551         reduced here, since anyway that computation doesn't work.
6552         * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
6553         (rule_useless_p, rule_never_reduced_p): New.

6559         reduced to...
6560         (token_actions): here.
6561         * src/main.c (main): Make the parser before making the report, so
6562         that rules never reduced are computed.
6563         Call grammar_rules_never_reduced_report.
6564         * src/print.c (print_results): Report rules never reduced.
6565         * tests/conflicts.at, tests/reduce.at: Adjust.
6566
6567 2002-08-01  Akim Demaille  <akim@epita.fr>
6568
6569         Instead of attaching lookaheads and duplicating the rules being
6570         reduced by a state, attach the lookaheads to the reductions.
6571
6572         * src/state.h (state_t): Remove the `lookaheads',
6573         `lookaheads_rule' member.
6574         (reductions_t): Add a `lookaheads' member.
6575         Use a regular array for the `rules'.
6576         * src/state.c (reductions_new): Initialize the lookaheads member
6577         to 0.
6578         (state_rule_lookaheads_print): Adjust.
6579         * src/state.h, src/state.c (state_reductions_find): New.

6581         (count_rr_conflicts): Adjust.

6584         (state_lookaheads_count): New.
6585         (states_lookaheads_initialize): Merge into...
6586         (initialize_LA): this.
6587         (lalr_free): Adjust.
6588         * src/main.c (main): Don't free nullable and derives too early: it
6589         is used by --verbose.
6590         * src/print.c, src/print_graph.c, src/tables.c: Adjust.
6591
6592 2002-08-01  Akim Demaille  <akim@epita.fr>
6593
6594         * src/derives.h, src/derives.c (derives): A `rule_t***' instead of
6595         `rule_number_t**'.
6596         (set_derives, free_derives): Rename as...
6597         (derives_compute, derives_free): this.
6598         Adjust all dependencies.

6601         (rule_list_t): Store rule_t *, not rule_number_t.
6602         * src/state.c (state_rule_lookaheads_print): Directly compare rule
6603         pointers, instead of their numbers.
6604         * src/main.c (main): Call nullable_free, and derives_free earlier,
6605         as they were lo longer used.
6606
6607 2002-08-01  Akim Demaille  <akim@epita.fr>
6608
6609         * lib/timevar.c (get_time): Include children time.

6612         * src/lalr.c (LA, LArule): Static.
6613         * src/lalr.h, src/lalr.c (lalr_free): New.
6614         * src/main.c (main): Call it.
6615         * src/tables.c (pack_vector): Check whether loc is >= to the
6616         table_size, not >.
6617         (pack_tables): Don't free froms, tos, conflict_tos, and pos...
6618         (tables_generate): do it, since that's also it which allocates
6619         them.
6620         Don't free LA and LArule, main does.
6621
6622 2002-07-31  Akim Demaille  <akim@epita.fr>

6669         * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
6670         (long_options, short_options): --trace/-T takes an optional
6671         argument.
6672         Change all the uses of trace_flag to reflect the new flags.
6673         * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
6674
6675         Strengthen `stage' portability.
6676
6677         * m4/stage.m4 (BISON_PREREQ_STAGE): New.
6678         * configure.in: Use it.
6679         Don't check for malloc.h and sys/times.h.
6680         * src/system.h: Include them when appropriate.
6681         * src/main.c (stage): Compile only when mallinfo, struct mallinfo,
6682         times and struct tms are available.
6683
6684 2002-07-30  Akim Demaille  <akim@epita.fr>
6685
6686         In verbose parse error message, don't report `error' as an
6687         expected token.
6688         * tests/actions.at (Printers and Destructors): Adjust.
6689         * tests/calc.at (Calculator $1): Adjust.
6690         * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose

6692         that state.

6704 2002-07-30  Akim Demaille  <akim@epita.fr>
6705
6706         Report rules which are never reduced by the parser: those hidden
6707         by conflicts.
6708
6709         * src/LR0.c (save_reductions): Don't make the final state too
6710         different: save its reduction (accept) instead of having a state
6711         without any action (no shift or goto, no reduce).
6712         Note: the final state is now a ``regular'' state, i.e., the
6713         parsers now contain `reduce 0' as default reduction.
6714         Nevertheless, since they decide to `accept' when yystate =
6715         final_state, they still will not reduce rule 0.
6716         * src/print.c (print_actions, print_reduction): Adjust.
6717         * src/output.c (action_row): Track reduced rules.

6724         Initiate its autoconfiscation.
6725
6726         * configure.in: Look for malloc.h and sys/times.h.
6727         * src/main.c (stage): Adjust.
6728         Report only when trace_flag.
6729

6745         (endtoken, accept): these.
6746         * src/reader.c (reader): Set endtoken's default tag to "$end".
6747         Set undeftoken's tag to "$undefined" instead of "$undefined.".
6748         * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
6749         Adjust.
6750
6751 2002-07-29  Akim Demaille  <akim@epita.fr>
6752
6753         * src/reduce.c (reduce_grammar): When the language is empty,
6754         complain about the start symbol, not the axiom.
6755         Use its location.

6757

6761         yycontrol without making too strong assumptions on the parser
6762         itself.
6763         * src/output.c (prepare_tokens): Use the real 0th value of
6764         token_translations instead of `0'.
6765         * src/parse-gram.y (yyerror): Don't rely on yycontrol being
6766         visible here.
6767         * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
6768         for the time being: %locations ought to provide it to yyerror.
6769
6770 2002-07-25  Akim Demaille  <akim@epita.fr>
6771
6772         * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

7842         Use more modest sizes, as for the time being the parser does not

7932
7933         Remove `%thong' support as it is undocumented, unused, duplicates
7934         `%token's job, and creates useless e-mail traffic with people who

8313         Note: this patch partially drops `semantic-parser' support: it
8314         always does `rule_length - n', where semantic parsers ought to
8315         always use `-n'.

8386         (union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYCOPY,
8387         YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
8388         if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial

8421
8422         * src/reader.c (token_translations_init): 256 is now the default
8423         value for the error token, i.e., it will be assigned another
8424         number if the user assigned 256 to one of her tokens.

8432 2002-04-22  Akim Demaille  <akim@epita.fr>

8466
8467 2002-04-09  Akim Demaille  <akim@epita.fr>
8468
8469         * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
8470         full stderr, and strip it according to the bison options, instead
8471         of composing the error message from different bits.
8472         This makes it easier to check for several error messages.
8473         Adjust all the invocations.
8474         Add an invocation exercising the error token.
8475         Add an invocation demonstrating a stupid error message.
8476         (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
8477         Adjust the tests.
8478         Error message are for stderr, not stdout.

8481
8482         * src/gram.h, src/gram.c (error_token_number): Remove, use
8483         errtoken->number.
8484         * src/reader.c (reader): Don't specify the user token number (2)
8485         for $undefined, as it uselessly prevents using it.
8486         * src/gram.h (token_number_t): Move to...
8487         * src/symtab.h: here.
8488         (state_t.number): Is a token_number_t.
8489         * src/print.c, src/reader.c: Use undeftoken->number instead of
8490         hard coded 2.
8491         (Even though this 2 is not the same as above: the number of the
8492         undeftoken remains being 2, it is its user token number which
8493         might not be 2).
8494         * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
8495         `user_token_number_max'.
8496         Output `undef_token_number'.
8497         * data/bison.simple, data/bison.c++: Use them.
8498         Be sure to map invalid yylex return values to
8499         `undef_token_number'.  This saves us from gratuitous SEGV.
8500

8502         (Unresolved SR Conflicts): Adjust.

8508         Adding #line.
8509         Remove the duplicate `typedefs'.
8510         (RhsNumberType): Fix the declaration and various other typos.
8511         Use __ofile__.
8512         * data/bison.simple: Use __ofile__.

8516
8517         * src/gram.h (item_number_t): New, the type of item numbers in
8518         RITEM.  Note that it must be able to code symbol numbers as
8519         positive number, and the negation of rule numbers as negative
8520         numbers.
8521         Adjust all dependencies (pretty many).
8522         * src/reduce.c (rule): Remove this `short *' pointer: use
8523         item_number_t.
8524         * src/system.h (MINSHORT, MAXSHORT): Remove.
8525         Include `limits.h'.
8526         Adjust dependencies to using SHRT_MAX and SHRT_MIN.
8527         (shortcpy): Remove.
8528         (MAXTABLE): Move to...
8529         * src/output.c (MAXTABLE): here.

8533         500.
8534         * tests/regression.at (Web2c Actions): Ajust.
8535
8536         Trying with bigger grammars shows various phenomena: at 3000 (28Mb
8537         of grammar file) bison is killed by my system, at 2000 (12Mb) bison
8538         passes, but produces negative #line number, once fixed, GCC is
8539         killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
8540         C), it passes.
8541         * src/state.h (state_h): Code input lines on ints, not shorts.
8542
8543 2002-04-08  Akim Demaille  <akim@epita.fr>

8690         * src/LR0.c (new_state): Display `nstates' as the name of the
8691         newly created state.
8692         Adjust to initialize first_state and last_state if needed.
8693         Be sure to distinguish the initial from the final state.
8694         (new_states): Create the itemset of the initial state, and use
8695         new_state.
8696         * src/closure.c (closure): Now that the initial state has its
8697         items properly set, there is no need for a special case when
8698         creating `ruleset'.
8699
8700         As a result, now the rule 0, reducing to $axiom, is visible in the
8701         outputs.  Adjust the test suite.
8702
8703         * tests/conflicts.at (Solved SR Conflicts)
8704         (Unresolved SR Conflicts): Adjust.

8709
8710         * src/LR0.c (allocate_itemsets): Don't loop over ritem: loop over
8711         the RHS of the rules.
8712         * src/output.c (output_gram): Likewise.
8713
8714 2002-04-07  Akim Demaille  <akim@epita.fr>
8715
8716         * src/gram.h (rule_t): `lhs' is now a pointer to the symbol's
8717         bucket.
8718         Adjust all dependencies.
8719         * src/reduce.c (nonterminals_reduce): Don't forget to renumber the
8720         `number' of the buckets too.
8721         * src/gram.h: Include `symtab.h'.
8722         (associativity): Move to...
8723         * src/symtab.h: here.
8724         No longer include `gram.h'.
8725

8730         * src/gram.h (rule_t): `number' is a new member.
8731         * src/reader.c (packgram): Set it.
8732         * src/reduce.c (reduce_grammar_tables): Move the useless rules at
8733         the end of `rules', and count them out of `nrules'.
8734         (reduce_output, dump_grammar): Adjust.
8735         * src/print.c (print_grammar): It is no longer needed to check for
8736         the usefulness of a rule, as useless rules are beyond `nrules + 1'.
8737         * tests/reduce.at (Reduced Automaton): New test.
8738
8739 2002-04-07  Akim Demaille  <akim@epita.fr>
8740
8741         * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
8742         lacking `+ 1' to nrules, Bison reported as useless a token if it
8743         was used solely to set the precedence of the last rule...
8744
8745 2002-04-07  Akim Demaille  <akim@epita.fr>
8746
8747         * data/bison.c++, data/bison.simple: Don't output the current file
8748         name in #line, to avoid useless diffs between two identical
8749         outputs under different names.
8750
8751 2002-04-07  Akim Demaille  <akim@epita.fr>
8752
8753         * src/closure.c, src/print.c, src/reader.c, src/reduce.c:
8754         Normalize loops to using `< nrules + 1', not `<= nrules'.
8755
8756 2002-04-07  Akim Demaille  <akim@epita.fr>
8757
8758         * TODO: Update.

8770         RHS, instead of being an index in RITEMS.

8773
8774         * doc/bison.texinfo: Update copyright date.

8776         (Symbols): Warn about running Bison in one character set,

8778         Warn about character code 256, too.
8779
8780 2002-04-03  Paul Eggert  <eggert@twinsun.com>
8781
8782         * src/bison.data (YYSTACK_ALLOC): Depend on whether
8783         YYERROR_VERBOSE is nonzero, not whether it is defined.

9040
9041         Remove the support for C++ namespace cleanliness; it was
9042         causing more problems than it was curing, since it didn't work
9043         properly on some nonstandard C++ compilers.  This can wait
9044         for a proper C++ parser.
9045
9046         * NEWS: Document this.
9047         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
9048         of C++, as it's treated like C now.
9049         * src/bison.simple (YYSTD): Remove.
9050         (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
9051         Treat C++ just like Standard C instead of trying to support
9052         namespace cleanliness.
9053
9054 2002-02-14  Akim Demaille  <akim@epita.fr>
9055
9056         * tests/regression.at (else): Adjust to Andreas' change.
9057
9058 2002-02-14  Akim Demaille  <akim@epita.fr>
9059
9060         * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
9061
9062 2002-02-13  Andreas Schwab  <schwab@suse.de>
9063
9064         * src/output.c (output_rule_data): Don't output NULL, it might
9065         not be defined yet.
9066
9067 2002-02-11  Robert Anisko  <robert@lrde.epita.fr>
9068
9069         * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
9070         (Copyright notice): Update.
9071
9072 2002-02-11  Akim Demaille  <akim@epita.fr>
9073
9074         * tests/regression.at (%nonassoc and eof): Don't include
9075         nonportable headers.
9076
9077 2002-02-08  Robert Anisko  <robert@lrde.epita.fr>
9078
9079         * data/bison.c++: Correct error recovery.  Make the user able to
9080         initialize the starting location.
9081
9082 2002-02-07  Akim Demaille  <akim@epita.fr>
9083
9084         * tests/input.at: New.
9085
9086 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
9087
9088         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
9089         more consistent when naming methods and variables.  Put preprocessor
9090         directives around tables only needed for debugging.
9091
9092 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
9093
9094         * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
9095         C++ parsers.
9096         (yy::b4_name::parse): Use print_.
9097
9098 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
9099
9100         * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
9101
9102 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
9103
9104         * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
9105         C++ parsers.
9106         (yy::b4_name::parse): Build verbose error messages, and use error_.
9107
9108 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
9109
9110         * data/bison.c++: Fix m4 quoting in comments.
9111
9112 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
9113
9114         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
9115         not expanded by m4.
9116
9117 2002-02-05  Akim Demaille  <akim@epita.fr>
9118
9119         * data/bison.c++: Adjust to the M4 back end.
9120         More is certainly needed.
9121
9122 2002-02-05  Akim Demaille  <akim@epita.fr>
9123
9124         Give a try to M4 as a back end.
9125
9126         * lib/readpipe.c: New, from wdiff.
9127         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
9128         BISON_HAIRY.
9129         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
9130         specific values.  Now it is m4 that performs the lookup.
9131         * src/parse-skel.y: Remove.
9132         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
9133         * src/output.c (actions_output, guards_output)
9134         (token_definitions_output): No longer keeps track of the output
9135         line number, hence remove the second argument.
9136         (guards_output): Check against the guard member of a rule, not the
9137         action member.
9138         Adjust callers.
9139         (output_skeleton): Don't look for the skeleton location, let m4 do
9140         that.
9141         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
9142         file will be used.
9143         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
9144         (prepare): Given that for the time being changesyntax is not
9145         usable in M4, rename the muscles using `-' to `_'.
9146         Define `defines_flag', `output_parser_name' and `output_header_name'.
9147         * src/output.h (actions_output, guards_output)
9148         (token_definitions_output): Adjust prototypes.
9149         * src/scan-skel.l: Instead of scanning the skeletons, it now
9150         processes the output of m4: `__oline__' and `#output'.
9151         * data/bison.simple: Adjust to be used by M4(sugar).
9152         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
9153         to date.
9154         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
9155         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
9156         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
9157         shamelessly stolen from CVS Autoconf.
9158
9159 2002-02-05  Akim Demaille  <akim@epita.fr>
9160
9161         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
9162         * configure.in: Check for the declarations of free and malloc.
9163         * src/muscle_tab.c: Adjust.
9164
9165 2002-02-05  Akim Demaille  <akim@epita.fr>
9166
9167         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
9168         which have no values.
9169
9170 2002-02-05  Akim Demaille  <akim@epita.fr>
9171
9172         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
9173         * data/: here.
9174
9175 2002-01-29  Paul Eggert  <eggert@twinsun.com>
9176
9177         * src/bison.simple (YYSIZE_T): Do not define merely because
9178         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
9179         On some platforms, <alloca.h> does not declare YYSTD (size_t).
9180
9181 2002-01-27  Akim Demaille  <akim@epita.fr>
9182
9183         Fix `%nonassoc and eof'.
9184
9185         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
9186         which were not properly copied!  Replace
9187         memcpy (res->errs, src->errs, src->nerrs);
9188         with
9189         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
9190         !!!
9191         * tests/regression.at (%nonassoc and eof): Adjust to newest
9192         Autotest: `.' is not in the PATH.
9193
9194 2002-01-27  Akim Demaille  <akim@epita.fr>
9195
9196         * tests/sets.at (AT_EXTRACT_SETS): New.
9197         (Nullable): Use it.
9198         (Firsts): New.
9199
9200 2002-01-26  Akim Demaille  <akim@epita.fr>
9201
9202         * tests/actions.at, tests/calc.at, tests/headers.at,
9203         * tests/torture.at: Adjust to the newest Autotest which no longer
9204         forces `.' in the PATH.
9205
9206 2002-01-25  Akim Demaille  <akim@epita.fr>
9207
9208         * tests/regression.at (%nonassoc and eof): New.
9209         Suggested by Robert Anisko.
9210
9211 2002-01-24  Akim Demaille  <akim@epita.fr>
9212
9213         Bison dumps core when trying to complain about broken input files.
9214         Reported by Cris van Pelt.
9215
9216         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
9217         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
9218         into...
9219         (Invalid inputs): Strengthen: exercise parse_percent_token.
9220
9221 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
9222
9223         * src/Makefile.am: Add bison.c++.
9224         * src/bison.c++: New skeleton.
9225
9226 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
9227
9228         * po/it.po: New.
9229
9230 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
9231
9232         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
9233
9234 2002-01-20  Marc Autret  <marc@gnu.org>
9235
9236         * src/files.c (compute_output_file_names): Fix
9237
9238 2002-01-20  Marc Autret  <marc@gnu.org>
9239
9240         * tests/output.at: New test.
9241         * src/files.c (compute_base_names): Don't map extensions when
9242         the YACC flag is set, use defaults.
9243         Reported by Evgeny Stambulchik.
9244
9245 2002-01-20  Marc Autret  <marc@gnu.org>
9246
9247         * src/system.h: Need to define __attribute__ away for non-GCC
9248         compilers as well (i.e., the vendor C compiler).
9249         Suggested by Albert Chin-A-Young.
9250
9251 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
9252
9253         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
9254         canonical definition.
9255         * src/system.h: Use the canonical definition for PARAMS (avoids
9256         a conflict with the macro from lib/hash.h).
9257
9258 2002-01-11  Akim Demaille  <akim@epita.fr>
9259
9260         * configure.in: Use AC_FUNC_STRNLEN.
9261         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
9262
9263 2002-01-09  Akim Demaille  <akim@epita.fr>
9264
9265         * src/files.c, src/files.h (output_infix): New.
9266         (tab_extension): Remove.
9267         (compute_base_names): Compute the former, drop the latter.
9268         * src/output.c (prepare): Insert the muscles `output-infix', and
9269         `output-suffix'.
9270         * src/parse-skel.y (string, string.1): New.
9271         (section.header): Use it.
9272         (section.yacc): Remove.
9273         (prefix): Remove too.
9274         * src/scan-skel.l: Adjust.
9275         * src/bison.simple, src/bison.hairy: Adjust.
9276
9277 2002-01-09  Akim Demaille  <akim@epita.fr>
9278
9279         * configure.in (WERROR_CFLAGS): Compute it.
9280         * src/Makefile.am (CFLAGS): Pass it.
9281         * tests/atlocal.in (CFLAGS): Idem.
9282         * src/files.c: Fix a few warnings.
9283         (get_extension_index): Remove, unused.
9284
9285 2002-01-08  Akim Demaille  <akim@epita.fr>
9286
9287         * src/getargs.c (AS_FILE_NAME): New.
9288         (getargs): Use it to convert DOSish file names.
9289         * src/files.c (base_name): Rename as full_base_name to avoid
9290         clashes with `base_name ()'.
9291         (filename_split): New.
9292         (compute_base_names): N-th rewrite, using filename_split.
9293
9294 2002-01-08  Akim Demaille  <akim@epita.fr>
9295
9296         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
9297         New, stolen from the Fileutils 4.1.
9298         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
9299         * configure.in: Check for the presence of memrchr, and of its
9300         prototype.
9301
9302 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
9303
9304         * lib/hash.h (__P): Added definition for this macro.
9305         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
9306         BUILT_SOURCES, to ensure they are generated first.
9307         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
9308         %error-verbose to allow bootstrapping with bison 1.30x.
9309
9310 2002-01-06  Akim Demaille  <akim@epita.fr>
9311
9312         * src/reader.c (parse_braces): Don't fetch the next char, the
9313         convention is to fetch on entry.
9314         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
9315         'switch' without a following semicolon.
9316         * tests/regression.at (braces parsing): New.
9317
9318 2002-01-06  Akim Demaille  <akim@epita.fr>
9319
9320         Bison is dead wrong in its RR conflict reports.
9321
9322         * tests/torture.at (GNU Cim Grammar): New.
9323         * src/conflicts.c (count_rr_conflicts): Fix.
9324
9325 2002-01-06  Akim Demaille  <akim@epita.fr>
9326
9327         Creating package.m4 from configure.ac causes too many problems.
9328
9329         * tests/Makefile.am (package.m4): Create it by hand,
9330         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
9331
9332 2002-01-06  Akim Demaille  <akim@epita.fr>
9333
9334         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
9335         skeleton.h.
9336
9337 2002-01-04  Paul Eggert  <eggert@twinsun.com>
9338
9339         * doc/bison.texinfo (Debugging):
9340         Remove YYSTDERR; it's no longer defined or used.
9341         Also, s/cstdio.h/cstdio/.
9342
9343 2002-01-03  Akim Demaille  <akim@epita.fr>
9344
9345         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
9346
9347 2002-01-03  Akim Demaille  <akim@epita.fr>
9348
9349         * src/parse-skel.y (process_skeleton): Don't bind the parser's
9350         tracing code to --trace, wait for a better --trace option, with
9351         args.
9352
9353 2002-01-03  Akim Demaille  <akim@epita.fr>
9354
9355         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
9356         The ISO C++ standard is extremely clear about it: stderr is
9357         considered a macro, not a regular symbol (see table 94 `Header
9358         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
9359         Therefore std:: does not apply to it.  It still does with fprintf.
9360         Also, s/cstdio.h/cstdio/.
9361
9362 2002-01-03  Akim Demaille  <akim@epita.fr>
9363
9364         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
9365         for non system headers.
9366
9367 2002-01-02  Akim Demaille  <akim@epita.fr>
9368
9369         Equip the skeleton chain with location tracking, runtime trace,
9370         pure parser and scanner.
9371
9372         * src/parse-skel.y: Request a pure parser, locations, and prefix
9373         renaming.
9374         (%union): Having several members with the same type does not help
9375         type mismatches, simplify.
9376         (YYPRINT, yyprint): New.
9377         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
9378         (skel_error): this.
9379         Handle locations.
9380         * src/scan-skel.l: Adjust to these changes.
9381         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
9382         (LOCATION_PRINT, skel_control_t): New.
9383
9384 2001-12-30  Akim Demaille  <akim@epita.fr>
9385
9386         * src/parse-skel.y: Get rid of the shift/reduce conflict:
9387         replace `gb' with BLANKS.
9388         * src/scan-skel.l: Adjust.
9389
9390 2001-12-30  Akim Demaille  <akim@epita.fr>
9391
9392         * src/system.h: We don't need nor want bcopy.
9393         Throw away MS-DOS crap: we don't need getpid.
9394         * configure.in: We don't need strndup.  It was even causing
9395         problems: because Flex includes the headers *before* us,
9396         _GNU_SOURCE is not defined by config.h, and therefore strndup was
9397         not visible.
9398         * lib/xstrndup.c: New.
9399         * src/scan-skel.l: Use it.
9400         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
9401         * src/parse-skel.y: Use %directives instead of #defines.
9402
9403 2001-12-30  Akim Demaille  <akim@epita.fr>
9404
9405         * src/skeleton.h: New.
9406         * src/output.c (output_parser, output_master_parser): Remove, dead
9407         code.
9408         * src/output.h (get_lines_number, actions_output, guards_output)
9409         (token_definitions_output): Prototype them.
9410         * src/parse-skel.y: Add the license notice.
9411         Include output.h and skeleton.h.
9412         (process_skeleton): Returns void, and takes a single parameter.
9413         * src/scan-skel.l: Add the license notice.
9414         Include skeleton.h.
9415         Don't use %option yylineno: it seems that then Flex imagines
9416         REJECT has been used, and therefore it won't reallocate its
9417         buffers (which makes no other sense to me than a bug).  It results
9418         in warnings for `unused: yy_flex_realloc'.
9419
9420 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
9421
9422         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
9423         (MUSCLE_INSERT_PREFIX): ...to there.
9424         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
9425         (MUSCLE_INSERT_PREFIX): Move from here...
9426
9427         * src/bison.hairy: Add a section directive.  Put braces around muscle
9428         names.  This parser skeleton is still broken, but Bison should not
9429         choke on a bad muscle 'syntax'.
9430         * src/bison.simple: Add a section directive.  Put braces around muscle
9431         names.
9432
9433         * src/files.h (strsuffix, stringappend): Add declarations.
9434         (tab_extension): Add declaration.
9435         (short_base_name): Add declaration.
9436
9437         * src/files.c (strsuffix, stringappend): No longer static.  These
9438         functions are used in the skeleton parser.
9439         (tab_extension): New.
9440         (compute_base_names): Use the computations done in this function
9441         to guess if the generated parsers should have '.tab' in their
9442         names.
9443         (short_base_name): No longer static.
9444
9445         * src/output.c (output_skeleton): New.
9446         (output): Disable call to output_master_parser, and give a try to
9447         a new skeleton handling system.
9448         (guards_output, actions_output): No longer static.
9449         (token_definitions_output, get_lines_number): No longer static.
9450
9451         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
9452
9453         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
9454         parse-skel.y.
9455
9456         * src/parse-skel.y: New file.
9457         * src/scan-skel.l: New file.
9458
9459 2001-12-29  Akim Demaille  <akim@epita.fr>
9460
9461         %name-prefix is broken.
9462
9463         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
9464         Adjust all dependencies.
9465         * tests/headers.at (export YYLTYPE): Strengthen this test: use
9466         %name-prefix.
9467
9468         Renaming yylval but not yylloc is not consistent.  Now we do.
9469
9470         * src/bison.simple: Prefix yylloc if used.
9471         * doc/bison.texinfo (Decl Summary): Document that.
9472
9473 2001-12-29  Akim Demaille  <akim@epita.fr>
9474
9475         * doc/bison.texinfo: Promote `%long-directive' over
9476         `%long_directive'.
9477         Remove all references to fixed-output-files, yacc is enough.
9478
9479 2001-12-29  Akim Demaille  <akim@epita.fr>
9480
9481         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
9482         user prologue.  These are defaults.
9483         * tests/actions.at (Mid-rule actions): Make sure the user can
9484         define YYDEBUG and YYERROR_VERBOSE.
9485
9486 2001-12-29  Akim Demaille  <akim@epita.fr>
9487
9488         * src/output.c (header_output): Don't forget to export YYLTYPE and
9489         yylloc.
9490         * tests/headers.at (export YYLTYPE): New, make sure it does.
9491         * tests/regression.at (%union and --defines, Invalid CPP headers):
9492         Move to...
9493         * tests/headers.at: here.
9494
9495 2001-12-29  Akim Demaille  <akim@epita.fr>
9496
9497         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
9498
9499 2001-12-29  Akim Demaille  <akim@epita.fr>
9500
9501         * tests/actions.at (Mid-rule actions): Output on a single line
9502         instead of several.
9503
9504 2001-12-29  Akim Demaille  <akim@epita.fr>
9505
9506         * doc/bison.texinfo: Formatting changes.
9507
9508 2001-12-29  Akim Demaille  <akim@epita.fr>
9509
9510         Don't store the token defs in a muscle, just be ready to output it
9511         on command.  Now possible via `symbols'.  Fixes a memory leak.
9512
9513         * src/output.c (token_definitions_output): New.
9514         (output_parser, header_output): Use it.
9515         * src/reader.c (symbols_save): Remove.
9516
9517 2001-12-29  Akim Demaille  <akim@epita.fr>
9518
9519         * src/bison.simple: Do not provide a default for YYSTYPE and
9520         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
9521         default.
9522
9523 2001-12-29  Akim Demaille  <akim@epita.fr>
9524
9525         Mid-rule actions are simply... ignored!
9526
9527         * src/reader.c (readgram): Be sure to attach mid-rule actions to
9528         the empty-rule associated to the dummy symbol, not to the host
9529         rule.
9530         * tests/actions.at (Mid-rule actions): New.
9531
9532 2001-12-29  Akim Demaille  <akim@epita.fr>
9533
9534         Memory leak.
9535
9536         * src/reader.c (reader): Free grammar.
9537
9538 2001-12-29  Akim Demaille  <akim@epita.fr>
9539
9540         Memory leak.
9541
9542         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
9543         since it allocates it for each state, although only one is needed.
9544         (allocate_storage): Do it here.
9545
9546 2001-12-29  Akim Demaille  <akim@epita.fr>
9547
9548         * src/options.h, src/options.c (create_long_option_table): Rename
9549         as...
9550         (long_option_table_new): this, with a clearer prototype.
9551         (percent_table): Remove, unused,
9552         * src/getargs.c (getargs): Adjust.
9553
9554 2001-12-29  Akim Demaille  <akim@epita.fr>
9555
9556         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
9557         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
9558         as states.
9559
9560 2001-12-29  Akim Demaille  <akim@epita.fr>
9561
9562         * src/lalr.c (build_relations): Rename `states' as `states1'.
9563         Sorry, I don't understand exactly what it is, no better name...
9564
9565 2001-12-29  Akim Demaille  <akim@epita.fr>
9566
9567         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
9568         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
9569         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
9570         as rules.
9571
9572 2001-12-29  Akim Demaille  <akim@epita.fr>
9573
9574         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
9575         ago.
9576
9577 2001-12-29  Akim Demaille  <akim@epita.fr>
9578
9579         * src/reader.c, src/reader.h (user_toknums): Remove.
9580         Adjust all users to use symbols[i]->user_token_number.
9581
9582 2001-12-29  Akim Demaille  <akim@epita.fr>
9583
9584         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
9585         Adjust all users to use symbols[i]->prec or ->assoc.
9586
9587 2001-12-29  Akim Demaille  <akim@epita.fr>
9588
9589         * src/reader.c, src/reader.h (tags): Remove.
9590         Adjust all users to use symbols[i]->tag.
9591
9592 2001-12-29  Akim Demaille  <akim@epita.fr>
9593
9594         * src/gram.h, src/gram.c (symbols): New, similar to state_table
9595         and rule_table.
9596         * src/reader.c (packsymbols): Fill this table.
9597         Drop sprec.
9598         * src/conflicts.c (resolve_sr_conflict): Adjust.
9599         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
9600         single table.
9601         Use symbols[i]->tag instead of tags[i].
9602
9603 2001-12-29  Akim Demaille  <akim@epita.fr>
9604
9605         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
9606         In addition, put a comment in there, to replace...
9607         * tests/regression.at (%union and C comments): Remove.
9608
9609 2001-12-29  Akim Demaille  <akim@epita.fr>
9610
9611         * tests/regression.at (Web2c Actions): Blindly move the actual
9612         output as expected output.  The contents *seem* right to me, but I
9613         can't pretend reading perfectly parser tables...  Nonetheless, all
9614         the other tests pass correctly, the table look OK, even though the
9615         presence of `$axiom' is to be noted: AFAICS it is useless (but
9616         harmless).
9617
9618 2001-12-29  Akim Demaille  <akim@epita.fr>
9619
9620         * src/reader.c (readgram): Don't add the rule 0 if there were no
9621         rules read.  In other words, add it _after_ having performed
9622         grammar sanity checks.
9623         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
9624
9625 2001-12-29  Akim Demaille  <akim@epita.fr>
9626
9627         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
9628         visible, and some states have now a different number.
9629
9630 2001-12-29  Akim Demaille  <akim@epita.fr>
9631
9632         * src/reader.c (readgram): Bind the initial rule's lineno to that
9633         of the first rule.
9634         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
9635         (Solved SR Conflicts): Adjust rule 0's line number.
9636
9637 2001-12-29  Akim Demaille  <akim@epita.fr>
9638
9639         Fix the `GAWK Grammar' failure.
9640
9641         * src/LR0.c (final_state): Initialize to -1 so that we do compute
9642         the reductions of the first state which was mistakenly confused
9643         with the final state because precisely final_state was initialized
9644         to 0.
9645         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
9646         now noticed by Bison.
9647         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
9648         have a reduction on $default.
9649
9650 2001-12-29  Akim Demaille  <akim@epita.fr>
9651
9652         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
9653         rule line numbers.
9654         * src/closure.c (print_closure): Likewise.
9655         * src/derives.c (print_derives): Likewise.
9656         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
9657         now.
9658
9659 2001-12-29  Akim Demaille  <akim@epita.fr>
9660
9661         * src/lalr.c (lookaheads_print): New.
9662         (lalr): Call it when --trace-flag.
9663         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
9664         are dumped.
9665
9666 2001-12-29  Akim Demaille  <akim@epita.fr>
9667
9668         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
9669         when walking through ritem, even via rule->rhs.
9670         * src/reduce.c (dump_grammar, useful_production, reduce_output)
9671         (useful_production, useless_nonterminals): Likewise.
9672         (reduce_grammar_tables): Likewise, plus update nritems.
9673         * src/nullable.c (set_nullable): Likewise.
9674         * src/lalr.c (build_relations): Likewise.
9675         * tests/sets.at (Nullable): Adjust.
9676         Fortunately, now, the $axiom is no longer nullable.
9677
9678 2001-12-29  Akim Demaille  <akim@epita.fr>
9679
9680         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
9681         the 0-sentinel.
9682         * src/gram.c (ritem_longest_rhs): Likewise.
9683         * src/reduce.c (nonterminals_reduce): Likewise.
9684         * src/print_graph.c (print_graph): Likewise.
9685         * src/output.c (output_rule_data): Likewise.
9686         * src/nullable.c (set_nullable):  Likewise.
9687
9688 2001-12-29  Akim Demaille  <akim@epita.fr>
9689
9690         * src/output.c: Comment changes.
9691
9692 2001-12-27  Paul Eggert  <eggert@twinsun.com>
9693
9694         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
9695         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
9696         Sparc, as they were causing more porting problems than the
9697         (minor) performance improvement was worth.
9698
9699         Also, catch up with 1.31's YYSTD.
9700
9701 2001-12-27  Akim Demaille  <akim@epita.fr>
9702
9703         * src/output.c (output_gram): Rely on nritems, not the
9704         0-sentinel.  See below.
9705         Use -1 as separator, not 0.
9706         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
9707         Rely on -1 as separator in yyrhs, instead of 0.
9708         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
9709         twice `Now at end of input', therefore there are two lines less to
9710         expect.
9711
9712 2001-12-27  Akim Demaille  <akim@epita.fr>
9713
9714         * tests/regression.at (Unresolved SR Conflicts):
9715         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
9716         below.
9717
9718 2001-12-27  Akim Demaille  <akim@epita.fr>
9719
9720         * src/LR0.c (new_state): Recognize the final state by the fact it
9721         is reached by eoftoken.
9722         (insert_start_shifting_state, insert_eof_shifting_state)
9723         (insert_accepting_state, augment_automaton): Remove, since now
9724         these states are automatically computed from the initial state.
9725         (generate_states): Adjust.
9726         * src/print.c: When reporting a rule number to the user, substract
9727         1, so that the axiom rule is rule 0, and the first user rule is 1.
9728         * src/reduce.c: Likewise.
9729         * src/print_graph.c (print_core): For the time being, just as for
9730         the report, depend upon --trace-flags to dump the full set of
9731         items.
9732         * src/reader.c (readgram): Once the grammar read, insert the rule
9733         0: `$axiom: START-SYMBOL $'.
9734         * tests/set.at: Adjust: rule 0 is now displayed, and since the
9735         number of the states has changed (the final state is no longer
9736         necessarily the last), catch up.
9737
9738 2001-12-27  Akim Demaille  <akim@epita.fr>
9739
9740         Try to make the use of the eoftoken valid.  Given that its value
9741         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
9742         is used instead of > 0 where appropriate, (ii), depend upon nritems
9743         instead of the 0-sentinel.
9744
9745         * src/gram.h, src/gram.c (nritems): New.
9746         Expected to be duplication of nitems, but for the time being...
9747         * src/reader.c (packgram): Assert nritems and nitems are equal.
9748         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
9749         * src/closure.c (print_closure, print_fderives): Likewise.
9750         * src/gram.c (ritem_print): Likewise.
9751         * src/print.c (print_core, print_grammar): Likewise.
9752         * src/print_graph.c: Likewise.
9753
9754 2001-12-27  Akim Demaille  <akim@epita.fr>
9755
9756         * src/main.c (main): If there are complains after grammar
9757         reductions, then output the report anyway if requested, then die.
9758         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
9759         * src/reader.c (eoftoken): New.
9760         (parse_token_decl): If the token being defined has value `0', it
9761         is the eoftoken.
9762         (packsymbols): No longer hack `tags' to insert `$' by hand.
9763         Be sure to preserve the value of the eoftoken.
9764         (reader): Make sure eoftoken is defined.
9765         Initialize nsyms to 0: now eoftoken is created just like the others.
9766         * src/print.c (print_grammar): Don't special case the eof token.
9767         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
9768         lie anyway, albeit pleasant.
9769         * tests/calc.at: Exercise error messages with eoftoken.
9770         Change the grammar so that empty input is invalid.
9771         Adjust expectations.
9772         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
9773
9774 2001-12-27  Akim Demaille  <akim@epita.fr>
9775
9776         * configure.in: Check the protos of strchr ans strspn.
9777         Replace strchr if needed.
9778         * src/system.h: Provide the protos of strchr, strspn and memchr if
9779         missing.
9780         * lib/strchr.c: New.
9781         * src/reader.c (symbols_save): Use strchr.
9782
9783 2001-12-27  Akim Demaille  <akim@epita.fr>
9784
9785         * src/print.c, src/print_graph.c (escape): New.
9786         Use it to quote the TAGS outputs.
9787         * src/print_graph.c (print_state): Now errors are in red, and
9788         reductions in green.
9789         Prefer high to wide: output the state number on a line of its own.
9790
9791 2001-12-27  Akim Demaille  <akim@epita.fr>
9792
9793         * src/state.h, src/state.c (reductions_new): New.
9794         * src/LR0.c (set_state_table): Let all the states have a
9795         `reductions', even if reduced to 0.
9796         (save_reductions): Adjust.

9799         * src/output.c (action_row): Adjust.
9800
9801 2001-12-27  Akim Demaille  <akim@epita.fr>
9802
9803         * src/state.h, src/state.c (errs_new, errs_dup): New.
9804         * src/LR0.c (set_state_table): Let all the states have an errs,
9805         even if reduced to 0.
9806         * src/print.c (print_errs, print_reductions): Adjust.
9807         * src/output.c (output_actions, action_row): Adjust.
9808         * src/conflicts.c (resolve_sr_conflict): Adjust.
9809
9810 2001-12-27  Akim Demaille  <akim@epita.fr>
9811
9812         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
9813
9814 2001-12-27  Akim Demaille  <akim@epita.fr>
9815
9816         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
9817         * src/print.c: here.
9818         (lookaheadset, shiftset): New, used as additional storage by
9819         print_reductions.
9820         (print_results): Adjust.
9821         (print_shifts, print_gotos, print_errs): New, extracted from...
9822         (print_actions): here.
9823         * src/print_graph.c (print_actions): Remove dead code.
9824
9825 2001-12-27  Akim Demaille  <akim@epita.fr>
9826
9827         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
9828         `$n' and `@n'.
9829
9830 2001-12-27  Akim Demaille  <akim@epita.fr>
9831
9832         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
9833         (build_relations): Adjust.
9834
9835 2001-12-27  Akim Demaille  <akim@epita.fr>
9836
9837         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
9838         duplication.
9839
9840 2001-12-27  Akim Demaille  <akim@epita.fr>
9841
9842         * src/reader.c (packgram): Catch nitems overflows.
9843
9844 2001-12-27  Akim Demaille  <akim@epita.fr>
9845
9846         * src/files.c, src/files.h (guard_obstack): Remove.
9847         * src/output.c (output): Adjust.
9848         * src/reader.c (parse_braces): New, factoring...
9849         (copy_action, copy_guard): these two which are renamed as...
9850         (parse_action, parse_guard): these.
9851         As a voluntary consequence, using braces around guards is now
9852         mandatory.
9853
9854 2001-12-27  Akim Demaille  <akim@epita.fr>
9855
9856         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
9857         * src/reader.c (symbol_list): `guard' and `guard_line' are new
9858         members.
9859         (symbol_list_new): Adjust.
9860         (copy_action): action_line is the first line, not the last.
9861         (copy_guard): Just as for actions, store the `action' only, not
9862         the switch/case/break flesh.
9863         Don't parse the user action that might follow the guard, let...
9864         (readgram): do it, i.e., now, there can be an action after a
9865         guard.
9866         In other words the guard is just explicitly optional.
9867         (packgram): Adjust.
9868         * src/output.c (guards_output): New.
9869         (output_parser): Call it when needed.
9870         (output): Also free the guard and attrs obstacks.
9871         * src/files.c, src/files.h (obstack_save): Remove.
9872         (output_files): Remove.
9873         As a result, if one needs the former `.act' file, using an
9874         appropriate skeleton which requires actions and guards is now
9875         required.
9876         * src/main.c (main): Adjust.
9877         * tests/semantic.at: New.
9878         * tests/regression.at: Use `input.y' as input file name.
9879         Avoid 8+3 problems by requiring input.c when the test needs the
9880         parser.
9881
9882 2001-12-27  Akim Demaille  <akim@epita.fr>
9883
9884         * src/reader.c (symbol_list_new): Be sure to initialize all the
9885         fields.
9886
9887 2001-12-27  Akim Demaille  <akim@epita.fr>
9888
9889         All the hacks using a final pseudo state are now useless.
9890
9891         * src/LR0.c (set_state_table): state_table holds exactly nstates.
9892         * src/lalr.c (nLA): New.
9893         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
9894         instead of lookaheadsp from the pseudo state (nstate + 1).
9895
9896 2001-12-27  Akim Demaille  <akim@epita.fr>
9897
9898         * src/output.c (action_row, token_actions): Use a state_t instead
9899         of a integer, and nlookaheads instead of the following state's
9900         lookaheadsp.
9901
9902 2001-12-27  Akim Demaille  <akim@epita.fr>
9903
9904         * src/conflicts.c (log_resolution, flush_shift)

9906         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
9907         (conflicts_print, print_reductions): Use a state_t instead of an
9908         integer when referring to a state.
9909         As much as possible, depend upon nlookaheads, instead of the
9910         `lookaheadsp' member of the following state (since lookaheads of
9911         successive states are successive, the difference between state n + 1
9912         and n served as the number of lookaheads for state n).
9913         * src/lalr.c (add_lookback_edge): Likewise.
9914         * src/print.c (print_core, print_actions, print_state)
9915         (print_results): Likewise.
9916         * src/print_graph.c (print_core, print_actions, print_state)
9917         (print_graph): Likewise.
9918         * src/conflicts.h: Adjust.

9921
9922         * src/bison.hairy: Formatting/comment changes.
9923         ANSIfy.
9924         Remove `register' indications.
9925         Add plenty of `static'.
9926
9927 2001-12-27  Akim Demaille  <akim@epita.fr>
9928
9929         * src/output.c (prepare): Drop the muscle `ntbase' which
9930         duplicates ntokens.
9931         * src/bison.simple: Formatting/comment changes.
9932         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
9933         is an undocumented synonym.
9934
9935 2001-12-22  Akim Demaille  <akim@epita.fr>
9936
9937         * src/output.c (output_table_data): Change the prototype to use
9938         `int' for array ranges: some invocations do pass an int, not a
9939         short.
9940         Reported by Wayne Green.

9945         Reported by Mike Castle.
9946
9947         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
9948         * tests/regression.at (Web2c): Rename as...
9949         (Web2c Report): this.
9950         (Web2c Actions): New.
9951
9952 2001-12-22  Akim Demaille  <akim@epita.fr>
9953
9954         Reductions in web2c.y are improperly reported.
9955         Reported by Mike Castle.
9956
9957         * src/conflicts.c (print_reductions): Fix.
9958         * tests/regression.at (Web2c): New.
9959
9960 2001-12-18  Akim Demaille  <akim@epita.fr>
9961
9962         Some host fail on `assert (!"foo")', which expands to
9963         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
9964         Reported by Nelson Beebee.
9965
9966         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
9967         `#define it_succeeded 0' and `assert (it_succeeded)'.
9968
9969 2001-12-17  Marc Autret  <autret_m@epita.fr>
9970
9971         * src/bison.simple: Don't hard code the skeleton line and filename.
9972         * src/output.c (output_parser): Rename 'line' as 'output_line'.
9973         New line counter 'skeleton_line' (skeleton-line muscle).
9974
9975 2001-12-17  Paul Eggert  <eggert@twinsun.com>
9976
9977         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
9978         YYDEBUG must be defined to a nonzero value.
9979
9980         * src/bison.simple (yytname): Do not assume that the user defines
9981         YYDEBUG to a properly parenthesized expression.
9982
9983 2001-12-17  Akim Demaille  <akim@epita.fr>
9984
9985         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
9986         nlookaheads is a new member.
9987         Adjust all users.
9988         * src/lalr.h (nlookaheads): Remove this orphan declaration.
9989         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each

9995         * src/main.c (main): Don't open/close files, nor invoke lex_free,
9996         let...
9997         * src/reader.c (reader): Do it.
9998
9999 2001-12-17  Akim Demaille  <akim@epita.fr>
10000
10001         * src/conflicts.c (print_reductions): Formatting changes.

10010
10011         * src/output.c (output_obstack): Be static and rename as...
10012         (format_obstack): this, to avoid any confusion with files.c's
10013         output_obstack.
10014         * src/reader.h (muscle_obstack): Move to...
10015         * src/output.h: here, since it's defined in output.c.

10017 2001-12-17  Akim Demaille  <akim@epita.fr>
10018
10019         * src/output.c (action_row, save_column, default_goto)
10020         (sort_actions, matching_state, pack_vector): Better variable
10021         locality.

10023 2001-12-17  Akim Demaille  <akim@epita.fr>
10024

10035 2001-12-16  Marc Autret  <autret_m@epita.fr>
10036
10037         * src/output.c (actions_output): Fix. When we use %no-lines,
10038         there is one less line per action.
10039
10040 2001-12-16  Marc Autret  <autret_m@epita.fr>
10041
10042         * src/bison.simple: Remove a useless #line directive.
10043         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
10044         * src/output.c (get_lines_number): New.
10045         (output_parser): Adjust, now takes care about the lines of a
10046         output muscles.
10047         Fix line numbering.
10048         (actions_output): Computes the number of lines taken by actions.
10049         (output_master_parser): Insert new skeleton which is the name of

10061
10062         Make `make distcheck' work.
10063
10064         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
10065         system.h which uses libgettext.h.
10066
10067 2001-12-15  Akim Demaille  <akim@epita.fr>
10068
10069         * src/nullable.c (set_nullable): Useless rules must be skipped,
10070         otherwise, since we range over their symbols, we might look at a
10071         nonterminal which no longer ``exists'', i.e., it is not counted in
10072         `nvars', hence we overflow our arrays.

10082         * src/reader.c (parse_union_decl): No longer output to
10083         defines_obstack: its content can be found in the `stype' muscle
10084         anyway.

10094
10095         * src/reader.c (parse_union_decl): Instead of handling two obstack
10096         simultaneously, use one to define the `stype' muscle, and use the
10097         value of the latter to fill defines_obstack.
10098         (copy_comment): Remove.
10099         (copy_comment2): Work for a single obstack.
10100         Rename as...
10101         (copy_comment): this.
10102
10103 2001-12-15  Akim Demaille  <akim@epita.fr>
10104
10105         * src/lex.c, src/lex.h (xgetc): No longer static.
10106         * src/reader.c (parse_union_decl): Revamp.
10107
10108 2001-12-15  Akim Demaille  <akim@epita.fr>
10109
10110         Still making progress in separating Bison into (i) input, (ii)
10111         process, (iii) output: now we can directly output the parser file
10112         without using table_obstack at all.
10113
10114         * src/files.c, src/files.h (table_obstack): Bye bye.
10115         (parser_file_name): New.
10116         * src/files.c (compute_output_file_names): Compute it.
10117         * src/output.c (actions_output, output_parser)
10118         (output_master_parser): To a file instead of an obstack.
10119
10120 2001-12-15  Akim Demaille  <akim@epita.fr>
10121
10122         Attach actions to rules, instead of pre-outputting them to
10123         actions_obstack.
10124
10125         * src/gram.h (rule_t): action and action_line are new members.
10126         * src/reader.c (symbol_list): Likewise.
10127         (copy_action): Save the actions within the rule.
10128         (packgram): Save them in rule_table.
10129         * src/output.c (actions_output): New.
10130         (output_parser): Use it on `%%actions'.
10131         (output_rule_data): Don't free rule_table.
10132         (output): Do it.
10133         (prepare): Don't save the `action' muscle.
10134         * src/bison.simple: s/%%action/%%actions/.
10135
10136 2001-12-15  Akim Demaille  <akim@epita.fr>
10137
10138         * src/reader.c (copy_action): When --yacc, don't append a `;'
10139         to the user action: let it fail if lacking.
10140         Suggested by Arnold Robbins and Tom Tromey.
10141
10142 2001-12-14  Akim Demaille  <akim@epita.fr>
10143
10144         * src/lex.c (literalchar): Simply return the char you decoded, non
10145         longer mess around with obstacks and int pointers.
10146         Adjust all callers.
10147
10148 2001-12-14  Akim Demaille  <akim@epita.fr>
10149
10150         * src/lex.c (literalchar): Don't escape the special characters,
10151         just decode them, and keep them as char (before, eol was output as
10152         the 2 char string `\n' etc.).
10153         * src/output.c (output_rule_data): Use quotearg to output the
10154         token strings.
10155
10156 2001-12-13  Paul Eggert  <eggert@twinsun.com>
10157
10158         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
10159         Do not infringe on the global user namespace when using C++.
10160         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
10161         All uses of `fprintf' and `stderr' changed.
10162
10163         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
10164
10165 2001-12-13  Akim Demaille  <akim@epita.fr>
10166
10167         The computation of nullable is broken: it doesn't handle empty
10168         RHS's properly.
10169
10170         * tests/torture.at (GNU AWK Grammar): New.
10171         * tests/sets.at (Nullable): New.
10172         * src/nullable.c (set_nullable): Instead of blindly looping over
10173         `ritems', loop over the rules, and then over their rhs's.
10174
10175         Work around Autotest bugs.
10176
10177         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
10178         frame, because Autotest understand lines starting with a `+' as
10179         traces from the shell.  Then, they are not processed properly.
10180         Admittedly an Autotest bug, but we don't have time to wait for
10181         Autotest to catch up.
10182         * tests/regression.at (Broken Closure): Adjust to the new table
10183         frames.
10184         Move to...
10185         * tests/sets.at: here.
10186
10187 2001-12-13  Akim Demaille  <akim@epita.fr>
10188
10189         * src/closure.c (closure): Use nrules instead of playing tricks
10190         with BITS_PER_WORD.
10191
10192 2001-12-13  Akim Demaille  <akim@epita.fr>
10193
10194         * src/print.c (print_actions): Output the handling of `$' as the
10195         traces do: shifting the token EOF.  Before EOF was treated as a
10196         nonterminal.
10197         * tests/regression.at: Adjust some tests.
10198         * src/print_graph.c (print_core): Complete the set of items via
10199         closure.  The next-to-final and final states are still unsatisfying,
10200         but that's to be addressed elsewhere.
10201         No longer output the rule numbers, but do output the state number.
10202         A single loop for the shifts + gotos is enough, but picked a
10203         distinct color for each.
10204         (print_graph): Initialize and finalize closure.
10205
10206 2001-12-13  Akim Demaille  <akim@epita.fr>
10207
10208         * src/reader.c (readgram): Remove dead code, an strip useless
10209         braces.
10210         (get_type): Remove, unused.
10211
10212 2001-12-12  Akim Demaille  <akim@epita.fr>
10213
10214         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
10215         on that of lib/error.c.
10216
10217 2001-12-12  Akim Demaille  <akim@epita.fr>
10218
10219         Some hosts don't like `/' in includes.
10220
10221         * src/system.h: Include libgettext.h without qualifying the path.
10222         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
10223         $(top_srcdir).
10224
10225 2001-12-11  Marc Autret  <autret_m@epita.fr>
10226
10227         * src/output.c (output_parser): Remove useless muscle.
10228
10229 2001-12-11  Marc Autret  <autret_m@epita.fr>
10230
10231         * src/bison.simple: Remove #line just before %%epilogue. It
10232         is now handled in ...
10233         * src/reader.c (read_additionnal_code): Add the output of a
10234         #line for the epilogue.
10235
10236 2001-12-10  Marc Autret  <autret_m@epita.fr>
10237
10238         * src/reader.c (copy_definition): Re-use CPP-outed code which
10239         replace precedent remove.
10240         * src/bison.simple: Remove #line before %%prologue because
10241         %%input-line is wrong at this time.
10242
10243 2001-12-10  Marc Autret  <autret_m@epita.fr>
10244
10245         * src/reader.c (symbols_output): Clean up.
10246         * src/output.c (output_gram, output): Clean up.
10247
10248 2001-12-10  Akim Demaille  <akim@epita.fr>
10249
10250         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
10251         * src/LR0.c (set_state_table): here.
10252         * src/lalr.c (lalr): Call it.
10253
10254 2001-12-10  Akim Demaille  <akim@epita.fr>
10255
10256         * src/state.h (shifts): Remove the `number' member: shifts are
10257         attached to state, hence no longer need to be labelled with a
10258         state number.
10259
10260 2001-12-10  Akim Demaille  <akim@epita.fr>
10261
10262         Now that states have a complete set of members, the linked list of
10263         shifts is useless: just fill directly the state's shifts member.
10264
10265         * src/state.h (shifts): Remove the `next' member.
10266         * src/LR0.c (first_state, last_state): Remove.
10267         Adjust the callers.
10268         (augment_automaton): Don't look for the shifts that must be added
10269         a shift on EOF: it is those of the state we looked for!  But now,
10270         since shifts are attached, it is no longer needed to looking
10271         merely by its id: its number.
10272
10273 2001-12-10  Akim Demaille  <akim@epita.fr>
10274
10275         * src/LR0.c (augment_automaton): Better variable locality.
10276         Remove an impossible branch: if there is a state corresponding to
10277         the start symbol being shifted, then there is shift for the start
10278         symbol from the initial state.
10279
10280 2001-12-10  Akim Demaille  <akim@epita.fr>
10281
10282         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
10283         only when appropriate: when insert_start_shifting_state' is not
10284         invoked.
10285         * tests/regression.at (Rule Line Numbers): Adjust.
10286
10287 2001-12-10  Akim Demaille  <akim@epita.fr>
10288
10289         * src/LR0.c (augment_automaton): Now that all states have shifts,
10290         merge the two cases addition shifts to the initial state.
10291
10292 2001-12-10  Akim Demaille  <akim@epita.fr>
10293
10294         * src/lalr.c (set_state_table): Move to...
10295         * src/LR0.c: here.
10296         * src/lalr.c (lalr): Don't call it...
10297         * src/LR0.c (generate_states): do it.
10298         * src/LR0.h (first_state): Remove, only the table is used.
10299
10300 2001-12-10  Akim Demaille  <akim@epita.fr>
10301
10302         * src/LR0.h (first_shift, first_reduction): Remove.
10303         * src/lalr.c: Don't use first_shift: find shifts through the
10304         states.
10305
10306 2001-12-10  Akim Demaille  <akim@epita.fr>
10307
10308         * src/LR0.c: Attach shifts to states as soon as they are
10309         computed.
10310         * src/lalr.c (set_state_table): Instead of assigning shifts to
10311         state, just assert that the mapping was properly done.
10312
10313 2001-12-10  Akim Demaille  <akim@epita.fr>
10314
10315         * src/LR0.c (insert_start_shift): Rename as...
10316         (insert_start_shifting_state): this.
10317         (insert_eof_shifting_state, insert_accepting_state): New.
10318         (augment_automaton): Adjust.
10319         Better locality of the variables.
10320         When looking if the start_symbol is shifted from the initial
10321         state, using `while (... symbol != start_symbol ...)' sounds
10322         better than `while (... symbol < start_symbol ...)': If fail
10323         to see how the order between symbols could be relevant!
10324
10325 2001-12-10  Akim Demaille  <akim@epita.fr>
10326
10327         * src/getargs.h: Don't declare `spec_name_prefix' and
10328         `spec_file_prefix', declared by src/files.h.
10329         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
10330         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
10331         * src/output.c (prepare): Adjust.
10332         * src/reader.c (symbols_output): Likewise.
10333         * src/vmsgetargs.c: Vaguely adjust, but who cares?
10334
10335 2001-12-10  Akim Demaille  <akim@epita.fr>
10336
10337         * src/muscle_tab.c (muscle_init): NULL is a better default than
10338         `"0"'.
10339
10340 2001-12-10  Akim Demaille  <akim@epita.fr>
10341
10342         * src/reader.c (reader): Calling symbols_output once is enough.
10343
10344 2001-12-10  Akim Demaille  <akim@epita.fr>
10345
10346         Now that states have a complete set of members, the linked list of
10347         reductions is useless: just fill directly the state's reductions
10348         member.
10349
10350         * src/state.h (struct reductions): Remove member `number' and
10351         `next'.
10352         * src/LR0.c (first_reduction, last_reduction): Remove.
10353         (save_reductions): Don't link the new reductions, store them in
10354         this_state.
10355         * src/lalr.c (set_state_table): No need to attach reductions to
10356         states, it's already done.
10357         * src/output.c (output_actions): No longer free the shifts, then
10358         the reductions, then the states: free all the states and their
10359         members.
10360
10361 2001-12-10  Akim Demaille  <akim@epita.fr>
10362
10363         * src/options.c (OPTN, DRTV, BOTH): New.
10364         (option_table): Use them.
10365
10366         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
10367         the job of system.h.
10368         * src/options.c: Don't include stdio.h and xalloc.h for the same
10369         reasons.
10370
10371 2001-12-10  Akim Demaille  <akim@epita.fr>
10372
10373         * src/output.c (output, prepare): Make sure the values of the
10374         muscles `action' and `prologue' are 0-terminated.
10375
10376 2001-12-10  Akim Demaille  <akim@epita.fr>
10377
10378         Clean up GCC warnings.
10379
10380         * src/reader.c (copy_action): `buf' is not used.
10381         (parse_skel_decl): Be static.
10382         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
10383         * src/options.h (create_long_option_table): Have a real prototype.
10384         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
10385         (hash_delete_at): Return const void *.
10386         Adjust casts to preserve the const.

10388 2001-12-10  Akim Demaille  <akim@epita.fr>
10389
10390         * configure.in: Require 2.52g.
10391         M4 is not needed, but AUTOM4TE is.
10392         * m4/m4.m4: Remove.

10395 2001-12-10  Akim Demaille  <akim@epita.fr>
10396
10397         One structure for states is enough, even though theoretically
10398         there are LR(0) states and LALR(1) states.
10399
10400         * src/lalr.h (state_t): Remove.
10401         (state_table): Be state_t **, not state_t *.
10402         * src/state.h (core, CORE_ALLOC): Rename as...
10403         (state_t, STATE_ALLOC): this.
10404         Add the LALR(1) members: shifts, reductions, errs.
10405         * src/LR0.c (state_table): Rename as...
10406         (state_hash): this, to avoid name clashes with the global
10407         `state_table'.
10408         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
10409         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

10415
10416         * src/warshall.c (bitmatrix_print): New.
10417         (TC): Use it.
10418         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
10419         j must be the outer loop.

10432         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
10433         Rename as...
10434         (state_t.reductions, state_t.shifts): this.
10435
10436 2001-12-05  Akim Demaille  <akim@epita.fr>
10437
10438         * src/reduce.c (reduce_grammar_tables): No longer disable the
10439         removal of useless rules via CPP but via `if (0)', so that the
10440         compiler still check the code is valid.
10441         For instance, it should have noticed `rline' no longer exists: use
10442         the `line' member of rule_t.
10443         * src/gram.c (dummy, rline): Remove, unused.
10444
10445 2001-12-05  Akim Demaille  <akim@epita.fr>
10446
10447         * src/output.c (pack_vector): Use assert, not berror.
10448         * src/main.c (berror): Remove, unused.
10449
10450 2001-12-05  Akim Demaille  <akim@epita.fr>
10451
10452         New experimental feature: if --verbose --trace output all the
10453         items of a state, not only its kernel.
10454
10455         * src/print.c (print_core): If `trace_flag', then invoke closure
10456         before outputting the items of the state (print_core is no longer
10457         a correct name them).
10458         (print_results): Invoke new_closure/free_closure if needed.
10459
10460 2001-12-05  Akim Demaille  <akim@epita.fr>
10461
10462         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
10463         * src/closure.c, src/closure.h (itemsetsize): Rename as...
10464         (nitemset): for consistency with the rest of the project.
10465
10466 2001-12-05  Akim Demaille  <akim@epita.fr>
10467
10468         * src/closure.c (print_closure): Improve.
10469         (closure): Use it for printing input and output.
10470
10471 2001-12-05  Akim Demaille  <akim@epita.fr>
10472
10473         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
10474         indexed by nonterminals.
10475
10476 2001-12-05  Akim Demaille  <akim@epita.fr>
10477
10478         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
10479         what it was!).
10480         * src/warshall.h: Remove accidental duplication of the content.
10481
10482 2001-12-05  Akim Demaille  <akim@epita.fr>
10483
10484         * src/closure.c (set_fderives): De-obfuscate.
10485
10486 2001-12-05  Akim Demaille  <akim@epita.fr>
10487

10494 2001-12-05  Akim Demaille  <akim@epita.fr>
10495
10496         * src/output.c (action_row): De-obfuscate
10497         using the good o' techniques: arrays not pointers, variable
10498         locality, BITISSET, RESETBIT etc.
10499
10500 2001-12-05  Akim Demaille  <akim@epita.fr>
10501
10502         Pessimize the code to simplify it: from now on, all the states
10503         have a valid SHIFTS, which NSHIFTS is possibly 0.
10504
10505         * src/LR0.c (shifts_new): Be global and move to..
10506         * src/state.c, src/state.h: here.
10507         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
10508         * src/print_graph: Adjust.
10509
10510 2001-12-05  Akim Demaille  <akim@epita.fr>
10511
10512         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
10513         * src/conflicts.c: Use it.
10514         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
10515         incorrectly ``simplified''.
10516
10517 2001-12-05  Akim Demaille  <akim@epita.fr>
10518
10519         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
10520         using the good o' techniques: arrays not pointers, variable
10521         locality, BITISSET, RESETBIT etc.
10522
10523 2001-12-05  Akim Demaille  <akim@epita.fr>
10524
10525         * src/state.h (SHIFT_SYMBOL): New.
10526         * src/conflicts.c: Use it to deobfuscate.
10527
10528 2001-12-05  Akim Demaille  <akim@epita.fr>
10529
10530         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
10531         (print_reductions): De-obfuscate using the good o' techniques:
10532         arrays not pointers, variable locality, BITISSET.
10533
10534 2001-12-05  Akim Demaille  <akim@epita.fr>
10535
10536         * src/conflicts.c (print_reductions): Arrays, not pointers.
10537         Use BITISSET.
10538
10539 2001-12-05  Akim Demaille  <akim@epita.fr>
10540
10541         * src/conflicts.c (print_reductions): Pessimize, but clarify.
10542
10543 2001-12-05  Akim Demaille  <akim@epita.fr>
10544
10545         * src/conflicts.c (print_reductions): Improve variable locality.

10548
10549         * src/conflicts.c (print_reductions): Pessimize, but clarify.
10550
10551 2001-12-05  Akim Demaille  <akim@epita.fr>
10552
10553         * src/conflicts.c (print_reductions): Improve variable locality.
10554
10555 2001-12-05  Akim Demaille  <akim@epita.fr>
10556
10557         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
10558         * src/lalr.c: Use them.
10559
10560 2001-12-05  Akim Demaille  <akim@epita.fr>
10561
10562         * src/LR0.c (augment_automaton): Formatting changes.
10563         Better variable locality.
10564
10565 2001-12-05  Akim Demaille  <akim@epita.fr>
10566
10567         * src/lalr.c (matrix_print): New.
10568         (transpose): Use it.
10569         Use arrays instead of pointers.
10570
10571 2001-12-05  Akim Demaille  <akim@epita.fr>
10572
10573         * src/lalr.c (maxrhs): Move to...
10574         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
10575         * src/lalr.c (build_relations): Adjust.
10576
10577 2001-12-05  Akim Demaille  <akim@epita.fr>
10578
10579         * src/lalr.c (transpose): Free the memory allocated to the
10580         argument, as it is replaced by the results by the unique caller.
10581         (build_relations): Merely invoke transpose: it handles the memory
10582         deallocation.
10583         Improve variable locality.
10584         Avoid variables used as mere abbreviations.
10585         (compute_lookaheads): Use arrays instead of pointers.
10586
10587 2001-12-05  Akim Demaille  <akim@epita.fr>
10588
10589         * src/lalr.c (initialize_F): Improve variable locality.
10590         Avoid variables used as mere abbreviations.
10591
10592 2001-12-05  Akim Demaille  <akim@epita.fr>
10593
10594         * src/derives.c (print_derives): Display the ruleno.
10595         * src/lalr.c (initialize_F, transpose): Better variable locality
10596         to improve readability.
10597         Avoid variables used as mere abbreviations.
10598
10599 2001-12-05  Akim Demaille  <akim@epita.fr>
10600
10601         * src/lalr.c (traverse): Use arrays instead of pointers.
10602
10603 2001-12-05  Akim Demaille  <akim@epita.fr>
10604
10605         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
10606         the handling of squeue.
10607         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
10608
10609 2001-12-05  Akim Demaille  <akim@epita.fr>
10610
10611         Because useless nonterminals are now kept alive (instead of being
10612         `destroyed'), we now sometimes examine them, and store information
10613         related to them.  Hence we need to know their number, and adjust
10614         memory allocations.
10615
10616         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
10617         static.
10618         * src/LR0.c (allocate_itemsets): The memory allocated to
10619         `symbol_count' was used for two different purpose: once to count
10620         the number of occurrences of each symbol, and later reassigned to
10621         `shift_symbol', containing the symbol that can be shifted from a
10622         given state.
10623         Deobfuscate, i.e., allocate, use and free `symbol_count' here
10624         only, and...
10625         (new_itemsets): Allocate `shift_symbol' here.
10626         (allocate_itemsets): symbol_count includes useless nonterminals.
10627         Make room for them.
10628         (free_storage): Use `free', not `XFREE', for pointers that cannot
10629         be null.
10630
10631 2001-12-05  Akim Demaille  <akim@epita.fr>
10632
10633         * src/nullable.c (set_nullable): Deobfuscate the handling of
10634         ritem.
10635         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
10636
10637 2001-12-05  Akim Demaille  <akim@epita.fr>
10638
10639         * src/gram.c, src/gram.h (ritem_print): New.
10640         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
10641         (This useless function was defined only to work around VMS linkers
10642         that can't handle compilation units with variables only).
10643         * src/reduce.c (dump_grammar): Use it to trace the construction of
10644         ritem.
10645
10646 2001-12-04  Paul Eggert  <eggert@twinsun.com>
10647
10648         * src/bison.simple (union yyalloc): Change member names
10649         to be the same as the stack names.
10650         (yyparse): yyptr is now union yyalloc *, not char *.
10651         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
10652         and may generate better code on some machines.
10653         (yystpcpy): Use prototype if __STDC__ is defined, not just
10654         if __cplusplus is defined.
10655
10656 2001-11-30  Akim Demaille  <akim@epita.fr>
10657
10658         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
10659         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
10660         Gettext doesn't compile cleanly, and dies with -Werror.
10661         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
10662         Include WARNING_CFLAGS here.
10663         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
10664         before being defined.
10665
10666 2001-11-27  Paul Eggert  <eggert@twinsun.com>
10667
10668         * lib/quotearg.h (quotearg_n, quotearg_n_style):
10669         First arg is int, not unsigned.
10670         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
10671         (SIZE_MAX, UINT_MAX): New macros.
10672         (quotearg_n_options): Abort if N is negative.
10673         Avoid overflow check on hosts where size_t is 64 bits and int
10674         is 32 bits, as overflow is impossible there.
10675         Fix off-by-one typo that caused unnecessary reallocation.
10676
10677 2001-11-29  Paul Eggert  <eggert@twinsun.com>
10678
10679         Name space cleanup in generated parser.
10680
10681         * doc/bison.texinfo (Bison Parser): Discuss system headers
10682         and their effect on the user name space.
10683
10684         * src/bison.simple:
10685         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
10686         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
10687         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
10688
10689         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
10690         on user names when possible.
10691
10692         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
10693         Simplify test for whather <alloca.h> exists.
10694
10695         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
10696
10697         (<stdio.h>): Include if YYDEBUG.
10698
10699         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
10700         ! defined (yyoverflow) && ! defined (yymemcpy).
10701
10702         (yymemcpy, yyparse): Rename local variables as needed so that
10703         they all begin with 'yy'.
10704
10705         (yystrlen, yystpcpy): New functions.
10706
10707         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
10708         All uses changed.
10709
10710         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
10711         instead of relying on string.h functions.  Use YYSTACK_ALLOC
10712         and YYSTACK_FREE instead of malloc and free.
10713
10714 2001-11-30  Akim Demaille  <akim@epita.fr>
10715
10716         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
10717         before their first uses.
10718         (YYBISON, YYPURE): Move to the top of the output.
10719

10724 2001-11-30  Akim Demaille  <akim@epita.fr>
10725
10726         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
10727         if body instead of `;' to pacify GCC's warnings.
10728
10729 2001-11-30  Akim Demaille  <akim@epita.fr>
10730
10731         Instead of mapping the LHS of unused rules to -1, keep the LHS
10732         valid, but flag the rules as invalid.
10733
10734         * src/gram.h (rule_t): `useful' is a new member.
10735         * src/print.c (print_grammar): Adjust.
10736         * src/derives.c (set_derives): Likewise.

10749
10750         * src/reduce.c (nonterminals_reduce): Instead of throwing away
10751         useless nonterminals, move them at the end of the symbol arrays.
10752         (reduce_output): Adjust.
10753         * tests/reduce.at (Useless Nonterminals): Adjust.

10755 2001-11-30  Akim Demaille  <akim@epita.fr>
10756
10757         * src/reduce.c: Various comment/formatting changes.
10758         (nonterminals_reduce): New, extracted from...
10759         (reduce_grammar_tables): here.
10760         (reduce_grammar): Call nonterminals_reduce.
10761
10762 2001-11-29  Paul Eggert  <eggert@twinsun.com>
10763
10764         * src/bison.simple (YYSTACK_REALLOC): Remove.
10765         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
10766         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
10767         New macros.
10768         (union yyalloc): New type.
10769         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
10770         an arbitrary restriction on hosts where size_t is wider than int.
10771
10772         (yyparse): Don't dump core if alloca or malloc fails; instead, report
10773         a parser stack overflow.  Allocate just one block of memory for all
10774         three stacks, instead of allocating three blocks; this typically is
10775         faster and reduces fragmentation.
10776
10777         Do not limit the number of items in the stack to a value that fits
10778         in 'int', as this is an arbitrary limit on hosts with 64-bit
10779         size_t and 32-bit int.

12161         the C Standard.
12162
12163 2001-08-27  Robert Anisko  <robert.anisko@epita.fr>
12164
12165         * src/output.c (output): Remove the initialization of the macro
12166         obstack.  It was done too late here.
12167

12169         completely wrong.

12206         string delimiters or not.
12207         (copy_string): Be a simple call to copy_string2 with the last argument
12208         bound to true.
12209         (read_declarations): Add case for macro definition.
12210         (copy_identifier): New.

12219
12220         * src/output.c (output_headers): Remove. The C code printed by this
12221         function should now be in the skeletons.
12222         (output_trailers): Remove.
12223         (output): Disable call to 'reader_output_yylsp'.
12224         (output_rule_data): Do not output tables to the table obstack.

12230         * src/output.c (output_token_translations): Associate 'translate'

12244
12245         * src/output.c (output_parser): Replace most of the skeleton copy code
12246         with something new. Skeletons are now processed character by character
12247         rather than line by line, and Bison looks for '%%' macros. This is the
12248         first step in making Bison's output process (a lot) more flexible.
12249         (output_parser): Use the macro table.

12576 2001-02-21  Akim Demaille  <akim@epita.fr>

12578         * src/reader.c (gensym): `gensym_count' is your own.
12579         Use a static buf to create the symbol name, as token_buffer is no
12580         longer a buffer.
12581
12582 2001-02-08  Akim Demaille  <akim@epita.fr>
12583
12584         * src/conflicts.c (conflict_report): Be sure not to append to res
12585         between two calls, which could happen if both first sprintf were

12589
12590         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
12591         New, from fileutils 4.0.37.
12592         * configure.in: Require Autoconf 2.49c.  I took some time before
12593         making this decision.  This is the only way out for portability
12594         issues in Bison, it would mean way too much duplicate effort to
12595         import in Bison features implemented in 2.49c since 2.13.
12596         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
12597
12598 2001-02-02  Akim Demaille  <akim@epita.fr>
12599

12603 2001-01-19  Akim Demaille  <akim@epita.fr>
12604
12605         Get rid of the ad hoc handling of token_buffer in the scanner: use
12606         the obstacks.
12607
12608         * src/lex.c (token_obstack): New.
12609         (init_lex): Initialize it.  No longer call...
12610         (grow_token_buffer): this.  Remove it.
12611         Adjust all the places which used it to use the obstack.
12612
12613 2001-01-19  Akim Demaille  <akim@epita.fr>
12614
12615         * src/lex.h: Rename all the tokens:
12616         s/\bENDFILE\b/tok_eof/g;
12617         s/\bIDENTIFIER\b/tok_identifier/g;
12618         etc.
12619         Let them be enums, not #define, to ease debugging.
12620         Adjust all the code.
12621
12622 2001-01-18  Akim Demaille  <akim@epita.fr>
12623

12626
12627 2001-01-18  Akim Demaille  <akim@epita.fr>
12628
12629         Since we now use obstacks, more % directives can be enabled.
12630
12631         * src/lex.c (percent_table): Also accept `%yacc',
12632         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
12633         `%debug'.
12634         Handle the actions for `%semantic_parser' and `%pure_parser' here,
12635         instead of returning a token.
12636         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
12637         * src/reader.c (read_declarations): Adjust.
12638         * src/files.c (open_files): Don't call `compute_base_names', don't
12639         compute `attrsfile' since they depend upon data which might be
12640         *in* the input file now.
12641         (output_files): Do it here.
12642         * src/output.c (output_headers): Document the fact that this patch
12643         introduces a guaranteed SEGV for semantic parsers.
12644         * doc/bison.texinfo: Document them.
12645         * tests/suite.at: Exercise these %options.
12646
12647 2000-12-20  Akim Demaille  <akim@epita.fr>
12648
12649         Also handle the output file (--verbose) with obstacks.
12650
12651         * files.c (foutput): Remove.
12652         (output_obstack): New.
12653         Adjust all dependencies.
12654         * src/conflicts.c: Return a string.
12655         * src/system.h (obstack_grow_string): Rename as...
12656         (obstack_sgrow): this.  Be ready to work with non literals.
12657         (obstack_fgrow4): New.

12665
12666         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
12667         (copy_dollar): Now that everything uses obstacks, get rid of the
12668         FILE * parameters.
12669
12670 2000-12-20  Akim Demaille  <akim@epita.fr>
12671
12672         * src/files.c (open_files): Actually the `.output' file is based
12673         on the short_base_name, not base_name.
12674         * tests/suite.at (Checking output file names): Adjust.
12675
12676 2000-12-20  Akim Demaille  <akim@epita.fr>
12677
12678         * src/bison.s1: Remove, we now use directly...

12693         vars.

12695         (output_files): Adjust.
12696         (base_name, short_base_name): Be global.
12697         Adjust dependencies.
12698
12699 2000-12-19  Akim Demaille  <akim@epita.fr>
12700
12701         * src/files.c (strsuffix): New.
12702         (stringappend): Be just like strcat but allocate.
12703         (base_names): Eve out from open_files.
12704         Try to simplify the rather hairy computation of base_name and
12705         short_base_name.
12706         (open_files): Use it.
12707         * tests/suite.at (Checking output file names): New test.

12712         (obstack_grow_string): this.
12713         * src/output.c (output_parser): Recognize `%% actions' instead of
12714         `$'.
12715         * src/bison.s1: s/$/%% actions/.
12716         * src/bison.hairy: Likewise.
12717
12718 2000-12-19  Akim Demaille  <akim@epita.fr>

12721         there are.
12722         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
12723         Suggested by Hans Aberg.
12724
12725 2000-12-19  Akim Demaille  <akim@epita.fr>
12726
12727         Let the handling of the skeleton files be local to the procedures
12728         that use it.
12729
12730         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
12731         longer static.

12746
12747         * src/files.c (open_files): Yipee!  We no longer need all the code
12748         looking for `/tmp' since we have no tmp file.
12749
12750 2000-12-19  Akim Demaille  <akim@epita.fr>
12751
12752         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
12753         New macros.
12754         * src/files.c (open_files): Less dependency on MSDOS etc.

12757
12758         * src/bison.s1 (YYLLOC_DEFAULT): New macro.
12759         Provide a default definition.
12760         Use it when executing the default @ action.
12761         * src/reader.c (reader_output_yylsp): No longer include
12762         `timestamp' and `text' in the default YYLTYPE.

12773         to escape special characters when outputting filenames.
12774         (ACTSTR_PROLOGUE, ACTSTR_EPILOGUE): Remove.
12775         (output_headers): Don't depend on them, Use ACTSTR.
12776
12777 2000-11-17  Akim Demaille  <akim@epita.fr>

12779         * lib/obstack.h: Formatting changes.
12780         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
12781         prevents type checking.
12782         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
12783         cast the value to (void *): assigning a `foo *' to a `void *'
12784         variable is valid.
12785         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
12786         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

12817

12834         `address' for consistency.  Qualify it `const'.

12849

12866         * src/main.c (main): Don't use `atexit' to register `done', since
12867         it no longer has to remove tmp files, just call `output_files'

12924         (getsym): Use it.
12925
12926         * src/output.c (output_short_table): New argument to display the

12974         When a literal string is used to define two different tokens,
12975         `bison -v' segfaults.
12976         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
12977

12984
12985         * src/reader.c (parse_expect_decl): Keep `count' within the size
12986         of `buffer'.
12987         From Neil Booth.
12988
12989 2000-10-02  Paul Eggert  <eggert@twinsun.com>
12990
12991         * bison.s1 (yyparse): Assign the default value
12992         unconditionally, to avoid a GCC warning and make the parser a
12993         tad smaller.
12994
12995 2000-10-02  Akim Demaille  <akim@epita.fr>
12996
12997         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
12998         options.
12999
13000 2000-10-02  Akim Demaille  <akim@epita.fr>
13001
13002         * src/derives.c, src/print.c, src/reduce.c: To ease the
13003         translation, move some `\n' out of the translated strings.
13004
13005 2000-10-02  Akim Demaille  <akim@epita.fr>
13006
13007         The location tracking mechanism is precious for parse error
13008         messages.  Nevertheless, it is enabled only when `@n' is used in
13009         the grammar, which is a different issue (you can use it in error
13010         message, but not in the grammar per se).  Therefore, there should
13011         be another means to enable it.
13012
13013         * src/getargs.c (getargs): Support `--locations'.
13014         (usage): Report it.
13015         * src/getargs.h (locationsflag): Export it.
13016         * src/lex.c (percent_table): Support `%locations'.
13017         * src/reader.c (yylsp_needed): Remove this variable, now replaced
13018         with `locationsflag'.
13019         * doc/bison.texinfo: Document `--locations' and `%locations'.
13020         Sort the options.
13021         * tests/calc.m4: Test it.
13022
13023         For regularity of the names, replace each
13024         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
13025         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
13026         In addition replace each `flag' with `_flag'.
13027
13028 2000-10-02  Akim Demaille  <akim@epita.fr>
13029
13030         Also test parse error messages, including with YYERROR_VERBOSE.
13031
13032         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
13033         associative).
13034         Use it to check the computations.
13035         Use it to check `nonassoc' is honored.
13036         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
13037         `--yyerror-verbose'.
13038         (_AT_CHECK_CALC): Adjust to this option.
13039         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
13040
13041 2000-10-02  Akim Demaille  <akim@epita.fr>
13042
13043         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
13044         the latter demonstrates a flaw in the handling of non debugging
13045         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
13046         was used in order to simplify:
13047
13048         #if YYDEBUG
13049         if (yydebug)
13050         {
13051         ...
13052         }
13053         #endif
13054
13055         into
13056
13057         if (yydebug)
13058         {
13059         ...
13060         }
13061
13062         unfortunately this leads to a CPP conflict when
13063         `--name-prefix=foo' is used since it produces `#define yydebug
13064         foodebug'.
13065
13066         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
13067         (YYDPRINTF): New macro.
13068         Spread its use.
13069         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
13070         the bison options.
13071         Also test `--verbose', `--defines' and `--name-prefix'.
13072
13073 2000-10-02  Akim Demaille  <akim@epita.fr>
13074
13075         Improve the readability of the produced parsers.
13076
13077         * src/bison.s1: Formatting changes.
13078         Improve the comment related to the `$' mark.
13079         (yydefault): Don't fall through to `yyresume': `goto' there.
13080         * src/output.c (output_parser): When the `$' is met, skip the end
13081         of its line.
13082         New variable, `number_of_dollar_signs', to check there's exactly
13083         one `$' in the parser skeleton.
13084
13085 2000-10-02  Akim Demaille  <akim@epita.fr>
13086
13087         * lib/xstrdup.c: New file, from the fileutils.
13088         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
13089         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
13090         instead of strlen + xmalloc + strcpy.
13091         * src/symtab.c (copys): Remove, use xstrdup instead.
13092
13093 2000-10-02  Akim Demaille  <akim@epita.fr>
13094
13095         * src/gram.h (associativity): New enum type which replaces the
13096         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
13097         `right_assoc', `left_assoc' and `non_assoc'.
13098         Adjust all dependencies.
13099         * src/reader.c: Formatting changes.
13100         (LTYPESTR): Don't define it, use it as a literal in
13101         `reader_output_yylsp'.
13102         * src/symtab.h (symbol_class): New enum type which replaces the
13103         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
13104         `sunknown', `stoken and `snterm'.

13106 2000-10-02  Akim Demaille  <akim@epita.fr>
13107
13108         * src/getargs.c (fixed_outfiles): Rename as...

13110         Adjust dependencies.
13111
13112 2000-10-02  Akim Demaille  <akim@epita.fr>
13113
13114         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
13115         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
13116         difficult and introduced a lot of core dump.  It turns out that
13117         Bison used an implementation of `xmalloc' based on `calloc', and
13118         at various places it does depend upon the initialization to 0.  I
13119         have not tried to isolate the pertinent places, and all the former
13120         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
13121         someone should address this issue.
13122
13123         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
13124         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
13125         files.
13126         Adjust dependencies.
13127         * src/warshall.h: New file.
13128         Propagate.

13130 2000-10-02  Akim Demaille  <akim@epita.fr>
13131
13132         Various anti-`extern in *.c' changes.
13133

13135
13136 2000-10-02  Akim Demaille  <akim@epita.fr>
13137
13138         * src/state.h (nstates, final_state, first_state, first_shift)
13139         (first_reduction): Move their exportation from here...
13140         * src/LR0.h: to here.
13141         Adjust dependencies.
13142         * src/getargs.c (statisticsflag): New variable.
13143         Add support for `--statistics'.
13144         Adjust dependencies.
13145
13146         Remove a lot of now useless `extern' statements in most files.

13154
13155         * src/print.h: New file.
13156         Propagate its use.
13157         * src/print.c: Formatting and ordering changes.
13158         (verbose, terse): Replace with...
13159         (print_results): this new function.
13160         Adjust dependencies.

13162 2000-10-02  Akim Demaille  <akim@epita.fr>

13223
13224         `user_toknums' is output as a `short[]' in `output.c', while it is
13225         defined as a `int[]' in `reader.c'.  For consistency with the

13242         order to get rid of the `static' prototypes.

13271         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

13492         There is now a pseudo variable @$ (readble and writable), location
13493         of the lhs of the rule (by default ranging from the location of
13494         the first symbol of the rhs, to the location of the last symbol,

13516
13517         * src/bison.s1 (#line): All set to `#line' only, since the

13529         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
13530         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
13531         One `#if YYDEBUG' remains, since it uses variables which are
13532         defined only if `YYDEBUG != 0'.

13566         the proper line number and file name.
13567         (DEFS): Propagate the location of bison library files and of the
13568         locale files.
13569         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
13570         builddir.
13571         * acinclude.m4: Remove, replaced by the directory m4.
13572         * m4/Makefile.am (EXTRA_DIST): New variable.

14252         (lex): Implemented "..." tokens.
14253         (literalchar, lex, parse_percent_token): Made tokenbuffer
14254         always contain the token.  This includes growing the token
14255         buffer while reading an integer.
14256         (parse_percent_token): Replaced if-else statement with percent_table.
14257         (parse_percent_token): Added % declarations as another
14258         way to specify the flags -n, -l, and -r.  Also added hooks for
14259         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
14260         major changes to files.c.
14261         (lex) Retain in the incoming stream a character following
14262         an incorrect '/'.
14263         (skip_white_space, lex):  Revised most error messages
14264         and changed fatal to warn to avoid aborting.
14265         (percent_table):  Added %thong declarations.
14266

14268
14269         * src/files.c (openfiles, open_extra_files, done):
14270          Add faction flag
14271         and actfile file.  Handle noparserflag.  Both for -n switch.
14272
14273         * src/conflicts.c (resolve_sr_conflict):
14274         Remove use of alloca.
