22 When reducing initial empty rules, Bison parser read an initial
23 location that is not defined. This results in garbage, and that
24 affects Bison's own parser. Therefore we need (i) to extend Bison
25 to support a means to initialize this location, and (ii) to use
26 this CVS Bison to fix CVS Bison's parser.
28 * src/reader.h, reader.c (epilogue_augment): Remove, replace
30 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
31 * src/parse-gram.y: Adjust.
32 (%initial-action): New.
33 (%error-verbose): Since we require CVS Bison, there is no reason
35 * src/scan-gram.l: Adjust.
36 * src/Makefile.am (YACC): New, to make sure we use our own parser.
37 * data/yacc.c (yyparse): Use b4_initial_action.
39 2003-08-25 Akim Demaille <akim@epita.fr>
41 * doc/bison.texinfo: Don't promote stdout for error messages.

58 2003-08-25 Akim Demaille <akim@epita.fr>
60 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
61 error recovery loops. This patch is based on
62 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
63 Also, augment the similarity between lalr1.cc and yacc.c.
64 Note: the locations of error recovery rules are not correct yet.
66 * data/lalr1.cc: Comment changes to augment the similarity between
68 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
69 (yyerrlab1): Remove, but where it used to be (now the bottom part of
70 yyerrlab), when hitting EOF, pop the whole stack here instead of
71 merely falling thru the default error handling mechanism.
72 (yyerrorlab): New label, with the old contents of YYERROR,
73 plus the following change: pop the stack of rhs corresponding
74 to the production that invoked YYERROR. That is how Yacc
75 behaves (required by POSIX).
76 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
79 2003-08-25 Akim Demaille <akim@epita.fr>
81 Tune local.at so that people can "autom4te -l autotest calc.at -o
82 calc" for instance, to extract a sub test suite.
84 * tests/testsuite.at: Move the initialization, Autotest version
85 requirement, and AT_TESTED invocation into...
86 * tests/local.at: here.
87 * tests/testsuite.at: Include it for compatibility with Autoconf
89 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should

94 Rework code slightly to avoid gcc -Wtraditional warnings.
95 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
96 The returned value is now stored in *YY0. All callers changed.
97 * src/output.c (merge_output): Adjust to the above change.
99 2003-07-26 Paul Eggert <eggert@twinsun.com>
101 * data/glr.c (YYASSERT): New macro.
102 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
103 yyresolveStates, yyprocessOneStack):
104 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
105 Derived from a suggestion by Frank Heckenbach.
107 2003-07-25 Paul Eggert <eggert@twinsun.com>
109 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
110 for portability to K&R C (after ansi2knr, presumably). See
111 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
112 by Frank Heckenbach, though I have omitted the structure-initialization
113 part of his glr-knr.diff patch since I recall that the Portable
114 C Compiler didn't require that change.
116 Let the user specify how to allocate and free memory.
117 Derived from a suggestion by Frank Heckenbach in

149 when printing sizes. Print sizes using an unsigned format.
150 Problem reported by Frank Heckenbach in

203 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
204 `How Can I Reset @code{yyparse}', since texinfo does not allow
205 arbitrary @ in node names.
207 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
208 shouldn't be needed according to the gettext 0.12.1 documentation
209 but which seem to be needed anyway: codeset.m4 glibc21.m4
210 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4

235 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
236 yyerror are declared before use; C99 requires this.
238 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
240 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
242 (yyrecoverSyntaxError): Correct the logic for setting and testing
244 Correct comment on handling EOF.
245 Allow states with only a default reduction, rather than failing

253 * src/reader.h (max_left_semantic_context): New variable declaration.

272 Remove forward declarations of yylex and yyerror---caused errors
273 because default YYLTYPE not yet defined.
274 Change semantic actions to compute strings, rather than printing
275 them directly (to test proper passing of semantics values). Change
276 output to prefix notation and update test data and expected results.
277 (yylex): Track locations.
278 (stmtMerge): Return value rather than printing, and include arguments
281 2003-06-03 Paul Eggert <eggert@twinsun.com>
283 Avoid warnings generated by GCC 2.95.4 when Bison is
284 configured with --enable-gcc-warnings.
285 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,

293 and $-N in GLR parsers): Remove unused local variable from yylex.
294 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
295 (void) as arg when not pure, since we now assume C89 when building
296 Bison. Pacify GCC by using parameter.
298 2003-06-02 Paul Eggert <eggert@twinsun.com>
300 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
301 yy::Location::lines, yy::Location::columns): Rename arguments
302 to avoid shadowing; this removes a warning generated by GCC 3.3.
304 2003-06-01 Paul Eggert <eggert@twinsun.com>
306 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
307 to g++, as GCC 3.3 complains if you do it.
308 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
309 everything that WARNING_CFLAGS has, except omit warnings
310 not suitable for C++.
311 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
312 * tests/atlocal.in (CXXFLAGS): New var.
313 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
315 Fix a GLR parser bug I reported in February; see
316 <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
317 The problem was that GLR parsers did not conform to the C standard,
318 because actions like { $1 = $2 + $3; } expanded to expressions
319 that invoked YYFILL in separate subexpressions, and YYFILL assigned
320 to a local variable. The C standard says that expressions
321 like (var = f ()) + (var = f ()) have undefined behavior.
322 Another problem was that GCC sometimes issues warnings that
323 yyfill and its parameters are unused.
325 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
327 (yyfill): New function.
329 (yyuserAction): Change type of yynormal to bool, so that it matches
330 the new yyfill signature. Mark it as possibly unused.
333 Follow up on a bug I reported in February, where a Bison-generated
334 parser can loop. Provide a test case and a fix for yacc.c. I
335 don't have a fix for lalr1.cc or for glr.c, unfortunately.
336 The original bug report is in:
337 <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
339 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
340 macro's size was becoming unwieldy.
341 (yyerrlab): Do not discard an empty lookahead symbol, as this
342 might destroy garbage.
343 (yyerrorlab): New label, with the old contents of YYERROR,
344 plus the following change: pop the stack of rhs corresponding
345 to the production that invoked YYERROR. That is how Yacc
346 behaves, and POSIX requires this behavior.
347 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
348 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
349 Define 'alarm' to do nothing if unistd.h is not available.
350 Add a new rule "exp: '-' error;" to test the above change to
351 data/yacc.c. Use 'alarm' to abort any test taking longer than
352 10 seconds, as it's probably looping.
353 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
354 Also, the new yacc.c generates two fewer diagnostics for an
357 2003-05-24 Paul Eggert <eggert@twinsun.com>
359 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
360 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
361 This fixes a problem reported by John Bowman when the Compaq/HP
362 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
364 * data/yacc.c (union yyalloc): Likewise.
365 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.

393 lbitset_xor_cmp): Likewise.
394 * lib/bbitset.h: Include <stdbool.h>.
395 (struct bitset_vtable): The following members now return bool, not

433 semicolon after a grammar declaration, in the interest of possible
434 future changes to the Bison input language.
435 Do not allow a stray semicolon at the start of the grammar.
436 (rhses.1): Allow one or more semicolons after any rule, including
437 just before "|" as required by POSIX.

441 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
443 %parse-param support for lalr1.cc.
445 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,

457 2003-05-12 Paul Eggert <eggert@twinsun.com>
459 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
460 English a bit. Fix fclose typo. Change "const char" to "char
461 const", and use ANSI C rather than K&R for "main". Suggest
462 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
463 and suggest yy_switch_to_buffer.
465 2003-05-05 Paul Eggert <eggert@twinsun.com>
467 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
468 C89. This avoids a diagnostic on compilers that define __STDC__
469 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
470 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
472 2003-05-03 Paul Eggert <eggert@twinsun.com>
474 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
475 Do not overrun array bounds.
476 This should fix a bug reported today by Olatunji Oluwabukunmi in
477 <http://mail.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
479 2003-04-29 Akim Demaille <akim@epita.fr>
481 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
482 * src/getargs.c, src/getargs.h: here, as bool, not int.
483 (nondeterministic_parser): New.
484 * src/parse-gram.y, src/scan-gram.l: Support
485 %nondeterministic-parser.
486 * src/output.c (prepare): Use nondeterministic_parser instead
487 of glr_parser where appropriate.
488 * src/tables.c (conflict_row, action_row, save_row)
489 (token_actions, token_actions, pack_vector): Ditto.
491 2003-04-29 Akim Demaille <akim@epita.fr>
493 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
495 2003-04-29 Akim Demaille <akim@epita.fr>
497 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
498 with %pure-parser and %locations to exercise the patch from Yakov
501 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
503 * data/yacc.c: (b4_lex_param): Corrected for the case where
504 %lex-param is provided and %pure-parser isn't.
506 2003-04-27 Paul Eggert <eggert@twinsun.com>
508 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
509 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
510 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
511 if it is not defined.
512 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
514 2003-04-26 Paul Eggert <eggert@twinsun.com>
516 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
517 Declare to be of type suitable for the ninf value itself, not of
518 type suitable for the corresponding table, since the latter might
519 be unsigned but the ninf value might be negative. This fixes a
520 bug reported by Alexandre Duret-Lutz in
521 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
523 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
524 invokes it. We shouldn't invoke it twice because it will attempt
525 to put error.o in the archive twice. This fixes a glitch reported
527 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
529 2003-04-21 Paul Eggert <eggert@twinsun.com>
531 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
534 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
536 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
537 Fix obvious typo that results in uncompilable GLR parsers
538 when both %pure-parser and %locations are used. (trivial change)
540 2003-04-17 Paul Eggert <eggert@twinsun.com>
542 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
543 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
544 Do not insert the expected token via unput, as this runs afoul
545 of a POSIX-compatibility bug in flex 2.5.31.
546 All uses changed to BEGIN the parent state,
547 since we no longer insert the expected token via unput.
548 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
549 that is no longer emitted after the above change.
551 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
552 the first one. This change is from Paul Hilfinger, and it fixes
553 regression reported by Werner Lemberg in
554 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
556 (resolve_sr_conflict): Don't invoke state_errs_set
557 unless one or more tokens have been explicitly made errors.
558 Otherwise, the above change causes Bison to abort.
560 * tests/existing.at (GNU pic Grammar): New test case, taken from
563 2003-03-31 Akim Demaille <akim@epita.fr>
565 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
567 2003-03-31 Akim Demaille <akim@epita.fr>
569 * src/output.c (prepare_symbols): Avoid trailing spaces in the
572 2003-03-31 Akim Demaille <akim@epita.fr>
574 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
577 2003-03-29 Akim Demaille <akim@epita.fr>
579 * m4/error.m4: Do not put under dynamic conditions some code which
580 expansion is under static control.
582 2003-03-29 Akim Demaille <akim@epita.fr>
584 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
586 2003-03-29 Akim Demaille <akim@epita.fr>
588 * doc/bison.texinfo (Strings are Destroyed): New.
590 2003-03-13 Paul Eggert <eggert@twinsun.com>
592 * .cvsignore: Add configure.lineno.
593 * src/.cvsignore: Add yacc.
594 * tests/.cvsignore: Add testsuite.log.
595 * doc/fdl.texi: Sync with latest FSF version.
597 2003-03-12 Paul Eggert <eggert@twinsun.com>
599 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
600 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
601 cursor, instead of leaving it undefined. This fixes a bug
602 reported by Tim Van Holder in
603 <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
604 * tests/input.at (Torturing the Scanner): Test the scanner on
605 an empty input file, which was Tim Van Holder's test case.
607 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
608 <sys/resource.h> can be included, include sys/time.h and
609 sys/times.h first, if available. This works around the SunOS
610 4.1.4 porting bug reported by Bruce Becker in
611 <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
613 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
614 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
617 Merge changes from gnulib. This was prompted because the CVS
618 snapshot didn't build on Solaris 7 due to strnlen problems.
620 These changes need to be merged back into gnulib:
621 * lib/hash.c: Include <stdbool.h> unconditionally.
622 * m4/onceonly.m4 (m4_quote): New macro.
623 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
624 Quote AC_FOREACH variable-expansions properly.
625 The 2003-01-03 obstack.h change also needs merging.
626 {end of changes requiring merging}
628 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
629 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
630 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
631 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
632 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
633 New files, imported from gnulib.
634 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
637 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
638 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
641 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
643 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
644 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
645 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
646 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
647 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
648 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
649 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
650 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
651 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
652 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
653 (jm_PREREQ_ARGMATCH): Remove.
654 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
655 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
657 * src/system.h: Include <stdbool.h> unconditionally.
659 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
660 assuming at least C89 in the bitset code for some time now.
662 2003-03-03 Akim Demaille <akim@epita.fr>
666 2003-03-02 Akim Demaille <akim@epita.fr>
668 * doc/bison.texinfo (Table of Symbols): Reactivate the
669 documentation for %lex-param, and %parse-param.
671 2003-03-02 Akim Demaille <akim@epita.fr>
673 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
674 generate verbose error messages.
675 Use the number of tokens as an upper bound in yytname, as it
676 cannot be a non terminal.
678 2003-03-02 Akim Demaille <akim@epita.fr>
680 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
683 2003-03-02 Akim Demaille <akim@epita.fr>
685 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
686 Use them to exercise yycheck overrun.
687 Based on Andrew Suffield's grammar.
689 2003-03-02 Akim Demaille <akim@epita.fr>
691 Create tests/local.at for Bison generic testing macros.
693 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
694 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
696 * tests/calc.at (AT_CHECK_CALC): Adjust.
697 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
698 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
699 * tests/local.at: here.
700 (AT_COMPILE_CXX): Tags the tests using it as c++.
701 Ignore the test if CXX is not functional.
703 2003-03-01 Paul Eggert <eggert@twinsun.com>
705 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
706 not loc->end, since loc->end might contain garbage and this leads
707 to undefined behavior on some platforms.
708 (id_loc, token_start): Use (IF_LINTed) initial values that do not
709 depend on *loc, so that the reader doesn't give the the false
710 impression that *loc is initialized.
711 (<INITIAL>"%%"): Do not bother setting code_start, since its value
712 does not survive the return.
714 2003-03-01 Akim Demaille <akim@epita.fr>
716 * src/scan-gram.l (code_start): Always initialize it when entering
717 into yylex, as SC_EPILOGUE is activated *before* the corresponding
718 yylex invocation. An alternative would be making it static, but
719 then it starts with the second %%'s beginning, instead of its end.
721 2003-02-28 Paul Eggert <eggert@twinsun.com>
723 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
724 around a UnixWare 7.1.1 porting bug reported by John Hughes in
725 <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
727 2003-02-26 Paul Eggert <eggert@twinsun.com>
729 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
730 Remove Sequent/Pyramid discussion (nobody uses them any more).
731 Merge VMS and MS-DOS discussion; these ports may well be dead
732 but let's keep mentioning them for now. Put <> around email
733 addresses. Add copyright notice.
735 2003-02-24 Paul Eggert <eggert@twinsun.com>
737 * data/glr.c (yy_reduce_print): yylineno -> yylno,
738 to avoid collision with flex use of yylineno.
739 Problem reported by Bruce Lilly in
740 <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

749 change integer types.
750 Suggested by Paul Eggert.
752 2003-02-21 Akim Demaille <akim@epita.fr>
754 * doc/bison.texinfo: Use "location" consistently to refer to @n,
755 to avoid confusions with lalr1.cc's notion of Position.
756 Suggested by Paul Eggert.
758 2003-02-20 Akim Demaille <akim@epita.fr>
760 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
761 before initial_columns.
762 (location.hh): Use consistent variable names when defining the
764 Use "last" so that we subtract from Positions, not from unsigned.
766 2003-02-20 Akim Demaille <akim@epita.fr>
768 * data/lalr1.cc (position.hh): New subfile, including the extended
769 and Doxygen'ed documentation of class Position.
770 (location.hh): Use it.
771 Document a` la Doxygen.
772 With the help of Benoit Perrot.
774 2003-02-20 Akim Demaille <akim@epita.fr>
776 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
778 Redefine AT_YYERROR_SEES_LOC_IF using it.
779 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
781 Don't use the location in yy::Parser::error_ and
782 yy::Parser::print_ when not %locations.
783 Activate more lalr1.cc tests.
785 2003-02-19 Akim Demaille <akim@epita.fr>
787 * data/lalr1.cc: When displaying a line number, be sure to make it
790 2003-02-19 Akim Demaille <akim@epita.fr>
792 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
794 (YYABORT, YYACCEPT, YYERROR): New.

800 error recovery, mixing with/without pops and discarding of the
803 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
805 2003-02-17 Paul Eggert <eggert@twinsun.com>
807 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
808 * tests/testsuite.at (AT_COMPILE): Use them.

842 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
843 locations in a more synthetic way.
844 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
846 Adjust the C locations to match those from Emacs: first column is
848 Change all the expected results.
849 Conform to the GCS: simplify the locations when applicable.
850 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)

967 described above (adapted from S. Eken).
968 Update copyright notice.
969 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
970 * tests/Makefile.am: Ditto.
972 2003-01-28 Paul Eggert <eggert@twinsun.com>
974 * data/lalr1.cc: Do not use @output_header_name@ unless
975 b4_defines_flag is set. This fixes two bugs reported by
977 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
978 and <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
980 2003-01-21 Paul Eggert <eggert@twinsun.com>
982 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
983 we don't need to worry about yyerrlab1 being reported as an
984 "unused label" by non-GCC C compilers. The downside is that if
985 locations are used then a couple of statements are duplicated each
986 time YYERROR is invoked, but the upside is that the warnings
988 (yyerrlab1): Move code to YERROR.
989 (yyerrlab2): Remove. Change uses back to yyerrlab1.
990 This reverts some of the 2002-12-27 change.
992 2003-01-17 Paul Eggert <eggert@twinsun.com>
994 * src/output.c (symbol_printers_output): Fix typo that led
995 to core dump. Problem reported by Antonio Rus in
996 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
998 2003-01-13 Akim Demaille <akim@epita.fr>,
999 Quoc Peyrot <chojin@lrde.epita.fr>,
1000 Robert Anisko <anisko_r@lrde.epita.fr>
1002 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
1003 when the stacks contain one element, as the loop would otherwise
1004 free the last state, and then use the top state (the one we just
1005 popped). This means that the initial elements will not be freed
1006 explicitly, as is the case in yacc.c; it is not a problem, as
1007 these elements have fake values.
1009 2003-01-11 Paul Eggert <eggert@twinsun.com>
1011 * NEWS: %expect-violations are now just warnings, reverting
1012 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
1013 bootstrapping problem reported by Matthias Klose; see
1014 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
1015 * src/conflicts.c (conflicts_print): Likewise.
1016 * tests/conflicts.at (%expect not enough, %expect too much,
1017 %expect with reduce conflicts): Likewise.
1018 * doc/bison.texinfo (Expect Decl): Document this. Also mention
1019 that the warning is enabled if the number of conflicts changes
1020 (not necessarily increases).
1022 * src/getargs.c (version): Update copyright year.
1024 2003-01-09 Akim Demaille <akim@epita.fr>
1026 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
1028 2003-01-08 Paul Eggert <eggert@twinsun.com>
1030 * Makefile.maint (WGETFLAGS):
1031 New macro, containing "-C off" to disable proxy caches.
1032 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
1033 (rel-check): Use $(WGET) instead of wget.
1035 2003-01-06 Paul Eggert <eggert@twinsun.com>
1037 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
1038 the GLR paper of Scott, Johnstone and Hussain.
1040 2003-01-04 Paul Eggert <eggert@twinsun.com>
1042 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
1043 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
1044 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
1045 (EXTRA_LIBRARIES): New var, for liby.a.
1046 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
1047 (EXTRA_SCRIPTS): New var, for yacc.
1049 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
1050 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
1051 Problem reported by Nelson H. F. Beebe.
1053 2003-01-03 Paul Eggert <eggert@twinsun.com>
1055 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
1056 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
1057 when compiling Bison 1.875's `bitset bset = obstack_alloc
1058 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
1060 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
1061 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
1062 grow to a huge size with typical invocation.
1064 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
1065 Use the pattern recommended by Autoconf 2.57, except also protect
1066 against double-definition.
1067 * src/system.h: Likewise.
1068 Portability issues reported by Nelson H. F. Beebe.
1070 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
1071 All uses changed. Provide a definition in both C and C++.
1072 (yytrue, yyfalse): Define even if defined (__cplusplus).
1074 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
1075 Reported by Nelson H. F. Beebe.
1077 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
1079 2003-01-02 Paul Eggert <eggert@twinsun.com>
1081 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
1082 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
1083 Bug reported by Nelson H. F. Beebe.
1085 2003-01-01 Paul Eggert <eggert@twinsun.com>
1089 2002-12-30 Paul Eggert <eggert@twinsun.com>
1091 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
1093 (<INITIAL>","): Here. This causes stray "," to be treated
1096 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
1097 last brace in braced code when not in Yacc mode, for compatibility
1098 with Bison 1.35. This resurrects the 2001-12-15 patch to
1101 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
1102 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
1104 2002-12-28 Paul Eggert <eggert@twinsun.com>
1106 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
1107 that of SYM's type. This fixes Debian bug 168069, reported by
1110 2002-12-28 Paul Eggert <eggert@twinsun.com>
1114 Switch back to the Yacc style of conflict reports, undoing some
1115 of the 2002-07-30 change.
1116 * doc/bison.texinfo (Understanding): Use Yacc style for
1117 conflict reports. Also, use new way of locating rules.
1118 * src/conflicts.c (conflict_report):
1119 Renamed from conflict_report_yacc, removing the old
1120 'conflict_report'. Translate the entire conflict report at once,
1121 so that we don't assume that "," has the same interpretation in
1123 (conflicts_output): Use Yacc-style conflict report for each state,
1124 instead of our more-complicated style.
1125 (conflicts_print): Use Yacc-style conflict report, except print
1126 the input file name when not emulating Yacc.
1127 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
1128 Conflicted Reduction, %expect not enough, %expect too much,
1129 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
1130 * tests/existing.at (GNU Cim Grammar): Likewise.
1131 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
1133 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
1134 fatal): Don't invoke fflush; it's not needed and it might even be
1135 harmful for stdout, as stdout might not be open.
1136 * src/reduce.c (reduce_print): Likewise.
1138 2002-12-27 Paul Eggert <eggert@twinsun.com>
1140 Fix a bug where error locations were not being recorded correctly.
1141 This problem was originally reported by Paul Hilfinger in
1142 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
1144 * data/yacc.c (yyparse): New local var yylerrsp, to record the
1145 top of the location stack's error locations.
1146 (yyerrlab): Set it. When discarding a token, push its location
1147 onto yylerrsp so that we don't lose track of the error's end.
1148 (yyerrlab1): Now is only the target of YYERROR, so that we can
1149 properly record the location of the action that failed. For GCC
1150 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
1151 GCC warning about yyerrlab1 being unused if YYERROR is unused.
1152 (yyerrlab2): New label, which yyerrlab now falls through to.
1153 Compute the error's location by applying YYLLOC_DEFAULT to
1154 the locations of all the symbols that went into the error.
1155 * doc/bison.texinfo (Location Default Action): Mention that
1156 YYLLOC_DEFAULT is also invoked for syntax errors.
1157 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
1158 Error locations include the locations of all the tokens that were
1159 discarded, not just the last token.
1161 2002-12-26 Paul Eggert <eggert@twinsun.com>
1163 * src/files.c: Include quote.h.
1164 (compute_output_file_names): Warn if we detect conflicting
1165 outputs to the same file. This should catch the misunderstanding
1166 exemplified by Debian Bug 165349, reported by Bruce Stephens..
1168 * src/conflicts.c (conflicts_print): If the user specifies
1169 "%expect N", report an error if there are any reduce/reduce
1170 conflicts. This is what the manual says should happen.
1171 This fixes Debian bug 130890, reported by Anthony DeRobertis.
1172 * tests/conflicts.at (%expect with reduce conflicts): New test.
1174 Don't use m4_include on relative file names, as it doesn't work as
1175 desired if there happens to be a file with that name under ".".
1177 * m4sugar/version.m4: Remove; it was included but it wasn't used.
1178 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
1179 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
1180 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
1181 * src/output.c (output_skeleton): Use full path names when
1182 specifying a file to include; don't rely on include path, as
1183 it's unreliable when the working file contains a file with
1186 2002-12-25 Paul Eggert <eggert@twinsun.com>
1188 Remove obsolete references to bison.simple and bison.hairy.
1189 Problem mentioned by Aubin Mahe in
1190 <http://mail.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
1191 * data/glr.c: Comment fix.
1192 * doc/bison.1: Remove references. Also, mention "yacc".
1194 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
1197 * src/parse-gram.y (declaration): Use enum "report_states" rather
1198 than its numeric value 1.
1200 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
1201 opening a new one. This fixes Debian bug 165349, reported by
1204 2002-12-24 Paul Eggert <eggert@twinsun.com>
1208 * Makefile.maint (cvs-update): Don't assume that the shell
1209 supports $(...), as Solaris sh doesn't.
1211 * src/parse-gram.y (lloc_default): Remove test for empty
1212 nonterminals at the end, since it didn't change the result.
1214 2002-12-24 Paul Eggert <eggert@twinsun.com>
1216 If the user does not define YYSTYPE as a macro, Bison now declares it
1217 using typedef instead of defining it as a macro. POSIX requires this.
1218 For consistency, YYLTYPE is also declared instead of defined.
1220 %union directives can now have a tag before the `{', e.g., the
1221 directive `%union foo {...}' now generates the C code
1222 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
1223 The default union tag is `YYSTYPE', for compatibility with Solaris 9
1224 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
1225 instead of `yyltype'.
1227 `yystype' and `yyltype' are now obsolescent macros instead of being
1228 typedefs or tags; they are no longer documented and will be
1229 withdrawn in a future release.
1231 * data/glr.c (b4_location_type): Remove.
1232 (YYSTYPE): Renamed from yystype.
1233 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
1234 (struct YYLTYPE): Renamed from struct yyltype.
1235 (YYLTYPE): Renamed from yyltype.
1236 (yyltype, yystype): New (and obsolescent) macros,
1237 for backward compatibility.
1238 * data/yacc.c: Likewise.
1240 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
1241 does not specify a union tag. This is for compatibility with
1244 * src/parse-gram.y (add_param): 2nd arg is now char * not char
1245 const *, since it is now modified by stripping surrounding { }.
1246 (current_braced_code): Remove.
1247 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
1248 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
1249 trailing " {...}". Now of type <chars>.
1250 (grammar_declaration): Adjust to bundled tokens.
1251 (code_content): Remove; stripping is now done by add_param.
1252 (print_token_value): Print contents of bundled tokens.
1253 (token_name): New function.
1255 * src/reader.h (braced_code, current_braced_code): Remove.
1256 (token_name): New decl.
1258 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
1259 token_type, not braced_code code_kind. All uses changed.
1260 (SC_PRE_CODE): New state, for scanning after a keyword that
1261 has (or usually has) an immediately-following braced code.
1262 (token_type): New local var, to keep track of which token type
1263 to return when scanning braced code.
1264 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
1265 <INITIAL>"%parse-param", <INITIAL>"%printer",
1266 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
1267 instead of returning a token type immediately.
1268 (<INITIAL>"{"): Set token type.
1269 (<SC_BRACED_CODE>"}"): Use it.
1270 (handle_action_dollar, handle_action_at): Now returns bool
1271 indicating success. Fail if ! current_rule; this prevents a core dump.
1272 (handle_symbol_code_dollar, handle_symbol_code_at):
1273 Remove; merge body into caller.
1274 (handle_dollar, handle_at): Complain in invalid contexts.
1276 * NEWS, doc/bison.texinfo: Document the above.
1277 * NEWS: Fix years and program names in copyright notice.
1279 2002-12-17 Paul Eggert <eggert@twinsun.com>
1281 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
1282 Reporting, Table of Symbols): Omit mentions of %lex-param and
1283 %parse-param from the documentation for now.
1285 2002-12-15 Paul Eggert <eggert@twinsun.com>
1287 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
1288 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
1289 lookahead symbol, and which sets yychar in parser actions) and it
1290 disagreed with the Bison documentation. Bug
1291 reported by Andrew Walrond.
1293 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
1294 as the caller now does that.
1295 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
1296 (YYEMPTY): Parenthesize right hand side, since others use it.
1297 (yyparse): Don't assume that our generated code is the only code
1300 2002-12-13 Paul Eggert <eggert@twinsun.com>
1304 POSIX requires a "yacc" command.
1305 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
1306 (MOSTLYCLEANFILES): Add yacc.
1308 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
1309 as an alias for bison y.
1311 * po/LINGUAS: Add da.
1313 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
1314 problem with latest <getopt.h>.
1315 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
1317 * doc/fdl.texi: Upgrade to 1.2.
1318 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
1319 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
1320 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
1322 * config/install-sh: Sync with autotools.
1324 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
1325 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
1326 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
1327 locations are requested.
1328 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
1329 locations are requested.
1331 2002-12-12 Paul Eggert <eggert@twinsun.com>
1333 Remove unportable casts and storage allocation tricks.
1334 While we're at it, remove almost all casts, since they
1335 usually aren't needed and are a sign of trouble.
1337 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
1339 * src/derives.c (derives_compute): Do not subtract NTOKENS from
1340 the pointer DSET returned by malloc; this isn't portable.
1341 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
1342 Similarly for DERIVES.
1343 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
1344 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
1345 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
1347 * src/derives.c (derives_compute): Do not bother invoking
1348 int_of_rule_number, since rule numbers are integers.
1350 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
1351 rather than XMALLOC (char, N).
1353 * src/files.c (filename_split): Rewrite to avoid cast.
1355 * src/gram.h (symbol_number_as_item_number,
1356 item_number_as_symbol_number, rule_number_as_item_number,
1357 item_number_as_rule_number):
1358 Now inline functions rather than macros, to avoid casts.
1359 * src/state.h (state_number_as_int): Likewise.
1360 * src/tables.c (state_number_to_vector_number,
1361 symbol_number_to_vector_number): Likewise.
1363 * src/gram.h (int_of_rule_number): Remove; no longer used.
1365 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
1366 since the resulting storage is always stored into.
1368 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
1371 * src/muscle_tab.c (muscle_m4_output):
1372 Now inline. Return bool, not int.
1373 * src/state.c (state_compare): Likewise.
1374 * src/symtab.c (symbol_check_defined,
1375 symbol_check_alias_consistency, symbol_pack, symbol_translation,
1376 hash_compare_symbol, hash_symbol):
1378 * src/uniqstr.c (uniqstr_print): Likewise.
1379 * src/muscle_tab.c (muscle_m4_output_processor):
1380 New function, to avoid casts.
1381 * src/state.c (state_comparator, stage_hasher): Likewise.
1382 * src/symtab.c (symbol_check_defined_processor,
1383 symbol_check_alias_consistency_processor, symbol_pack_processor,
1384 symbol_translation_processor, hash_symbol_comparator,
1385 hash_symbol_hasher): Likewise.
1386 * src/uniqstr.c (uniqstr_print_processor): Likewise.
1387 * src/muscle_tab.c (muscles_m4_output):
1388 Use new functions instead of casting old functions unportably.
1389 * src/state.c (state_hash_new): Likewise.
1390 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
1391 symbols_token_translations_init):
1393 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
1395 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
1396 var instead of casting to long, to avoid casts.
1397 (prepare_states): Use MALLOC rather than alloca, so that we don't
1398 have to worry about alloca.
1399 * src/state.c (state_hash_lookup): Likewise.
1401 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
1402 local var instead of casting to unsigned char, to avoid casts.
1404 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
1405 STATE_ALLOC): Remove.
1406 (transitions_new, errs_new, reductions_new, state_new): Use malloc
1407 rather than calloc, and use offsetof to avoid allocating slightly
1409 (state_new): Initialize all members.
1411 * src/state.c (state_hash): Use unsigned accumulator, not signed.
1413 * src/symtab.c (symbol_free): Remove; unused.
1414 (symbol_get): Remove cast in lhs of assignment.
1415 (symbols_do): Now static. Accept generic arguments, not
1416 hashing-related ones.
1418 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
1419 (symbol_processor): Remove.
1420 (symbols_do): Remove decl; now static.
1422 * src/system.h (alloca): Remove; decl no longer needed.
1423 (<stddef.h>): Include, for offsetof.
1424 (<inttypes.>, <stdint.h>): Include if available.
1425 (uintptr_t): New type, if system lacks it.
1426 (CALLOC, MALLOC, REALLOC): New macros.
1427 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
1430 * src/tables.c (table_size): Now int, to pacify GCC.
1431 (table_grow, table_ninf_remap): Use signed table size.
1432 (save_row): Don't bother initializing locals when not needed.
1433 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
1434 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
1436 * src/vcg.h: Correct misspellings.
1438 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
1441 * src/getargs.c (getargs): Don't assume EOF == -1.

1445 Change identifier spellings to avoid collisions with names
1446 that are reserved by POSIX.
1448 Don't use names ending in _t, since POSIX reserves them.
1449 For consistency, remove _e and _s endings -- they're weren't
1450 needed to remove ambiguity. All uses changed.

1526 value_t_as_yystype -> value_as_yystype.
1528 Don't include <errno.h> in the mainstream code, since it
1529 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
1530 * lib/get-errno.c, lib/get-errno.h: New files.
1531 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
1533 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.

1539 (handle_action_dollar, handle_action_at): Likewise.
1540 * src/system.h: Do not include <errno.h>.
1541 (TAB_EXT): Renamed from EXT_TAB.
1542 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
1544 Avoid str[a-z]*, since <string.h> reserves that name space.
1545 Change all instances of "struniq" in names to "uniqstr", and
1546 likewise for "STRUNIQ" and "UNIQSTR".
1547 * src/uniqstr.c: Renamed from src/struniq.c.

1586 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
1589 Sort include-file uses.
1591 Reorder all include files under src to be in the order "system.h".
1592 then the ../lib include files in angle brackets (alphabetized),
1593 then the . include files in double-quotes (alphabetized). Fix
1594 dependency breakages encountered in this process, as follows:
1595 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
1596 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
1597 * src/state.h: Include "symtab.h".
1599 2002-12-08 Paul Eggert <eggert@twinsun.com>
1601 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
1602 since this causes problems when __file__ contains character
1603 sequences like "@" that are treated specially by src/scan-skel.l.
1604 Instead, just use the file's basename. This fixes the bug
1605 reported by Martin Mokrejs in
1606 <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
1608 2002-12-06 Paul Eggert <eggert@twinsun.com>
1610 Add support for rules that do not have trailing semicolons, as
1611 POSIX requires. Improve the quality of locations in Bison
1614 * src/location.c: Include <quotearg.h>.
1615 (empty_location): Now const.
1616 (location_print): New function. Follow the recommendation of the
1617 GNU Coding Standards for locations that span file boundaries.
1618 * src/location.h: Do not include <quotearg.h>; no longer needed.
1619 (boundary): New type.
1620 (location_t): Use it. This allows locations to span file boundaries.
1621 All member uses changed: file -> start.file or end.file (as needed),
1622 first_line -> start.line, first_column -> start.column,
1623 last_line -> end.line, last_column -> end.column.
1624 (equal_boundaries): New function.
1625 (LOCATION_RESET, LOCATION_STEP): Remove.
1626 (LOCATION_PRINT): Remove. All callers changed to use location_print.
1627 (empty_location): Now const.
1628 (location_print): New decl.
1629 * src/parse-gram.y (lloc_default): New function, which handles
1630 empty locations more accurately.
1631 (YYLLOC_DEFAULT): Use it.
1632 (%token COLON): Remove.
1633 (%token ID_COLON): New token.
1635 (declarations, rules): Remove trailing semicolon.
1636 (declaration, rules_or_grammar_declaration):
1637 Allow empty (";") declaration.
1638 (symbol_def): Remove empty actions; no longer needed.
1639 (rules_or_grammar_declaration): Remove trailing semicolon.
1640 (semi_colon.opt): Remove.
1641 * src/reader.h: Include location.h.
1642 (scanner_cursor): New decl.
1643 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
1645 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
1647 (STEP): Remove. No longer needed, now that adjust_location does
1648 the work. All uses removed.
1649 (scanner_cursor): New var.
1650 (adjust_location): Renamed from extend_location. It now sets
1651 *loc and adjusts the scanner cursor. All uses changed.
1652 Don't bother testing for CR.
1653 (handle_syncline): Remove location arg; now updates scanner cursor.
1654 All callers changed.
1655 (unexpected_end_of_file): Now accepts start boundary of token or
1656 comment, not location. All callers changed. Update scanner cursor,
1658 (SC_AFTER_IDENTIFIER): New state.
1659 (context_state): Renamed from c_context. All uses changed.
1660 (id_loc, code_start, token_start): New local vars.
1661 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
1662 processing of Yacc white space and equivalents here.
1663 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
1664 instead of returning ID immediately, since we need to search for
1666 (<INITIAL>"'", "\""): Save token_start.
1667 (<INITIAL>"%{", "{", "%%"): Save code_start.
1668 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
1669 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
1670 BEGIN context_state at end, not INITIAL.
1671 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
1672 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
1673 Return correct token start.
1674 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
1675 the start of a character, string or multiline comment is found.
1676 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
1677 Reduction): Adjust reported locations to match the more-precise
1678 results now expected.
1679 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
1680 * tests/reduce.at (Useless Rules, Reduced Automaton,
1681 Underivable Rules): Likewise.
1682 * tests/regression.at (Invalid inputs): No longer `expecting ";"
1683 or "|"' now that so many other tokens are allowed by the new grammar.
1685 * src/complain.h (current_file): Remove duplicate decl;
1686 current_file is now owned by files.h.
1687 * src/complain.c, src/scan-gram.l: Include files.h.
1689 2002-12-06 Paul Eggert <eggert@twinsun.com>
1691 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
1692 promotes to int; it might be unsigned int.
1693 * data/yacc.c (yy_reduce_print): Likewise.
1695 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
1696 be #defined in the prologue, not in the Bison declarations.
1697 This fixes Debian Bug 102878, reported by Shaul Karl.
1699 2002-12-02 Paul Eggert <eggert@twinsun.com>
1701 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
1702 * lib/strtoul.c: New file, from gnulib.
1703 This fixes a porting bug reported by Peter Klein in
1704 <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
1706 2002-11-30 Paul Eggert <eggert@twinsun.com>
1708 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
1709 and put only a forward declaration in the prologue. This is for
1710 consistency with the other scanner helper functions.
1712 Type clashes now generate warnings, not errors, since it
1713 appears that POSIX may allow some grammars with type clashes.
1714 * src/reader.c (grammar_current_rule_check): Warn about
1715 type clashes instead of complaining.
1716 * tests/input.at (Type Clashes): Expect warnings, not complaints.
1718 Add Yacc library, since POSIX requires it.
1719 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
1720 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
1721 * lib/main.c, lib/yyerror.c: New files.
1723 gram_error can be static; it need not be extern.
1724 * src/reader.h (gram_error): Remove decl.
1725 * src/parse-gram.y (gram_error): Now static. Add static decl.
1726 (print_token_value): Omit parameter names from forward decl,
1729 2002-11-29 Paul Eggert <eggert@twinsun.com>
1731 * doc/bison.texinfo: Emphasize that yylex and yyerror must
1732 be declared before being used. E.g., one should typically
1733 declare them in the prologue. Use GNU coding style in examples.
1734 Put "const" consistently after the type it modifies. Mention
1735 that C99 supports "inline". Mention that yyerror traditionally
1738 %parse-param and %lex-param now take just one argument, the
1739 declaration; the argument name is deduced from the declaration.
1741 * doc/bison.texinfo (Parser Function, Pure Calling, Error
1742 Reporting, Table of Symbols): Document this.
1743 * src/parse-gram.y (add_param): New function.
1745 (declaration): Implement new rule for %parse-param and %lex-param.
1746 * src/scan-gram.l: "," now elicits a warning, rather than being
1747 a token; this is more compatible with byacc.
1748 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
1750 2002-11-27 Paul Eggert <eggert@twinsun.com>
1752 Rename identifiers to avoid real and potential collisions.
1754 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
1755 to avoid collision with lex macro described by Bruce Lilly in
1756 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
1757 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
1758 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
1759 * src/parse-gram.y (print_token_value): Renamed from yyprint.
1761 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
1762 The name "yycontrol" violates the name space rules, and this stuff
1763 wasn't being used anyway.
1764 (input): Remove action; this stuff wasn't being used.
1765 (gram_error): Rename local variable yylloc -> loc.
1766 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
1767 (YY_DECL): Don't use "yy" at start of local variables.
1768 All uses changed, e.g., yylloc -> loc.
1769 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
1770 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
1771 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
1772 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
1774 * src/parse-gram.y (gram_error): loc is now const *.
1775 * src/reader.h (gram_error): Likewise.
1777 2002-11-24 Paul Eggert <eggert@twinsun.com>
1781 * tests/actions.at (Actions after errors): Use an output format
1782 more similar to that of the Printers and Destructors test.
1783 Test the position of the ';' token too.
1784 (Printers and Destructors): Likewise.
1785 (Printers and Destructors: %glr-parser): Remove for now, to avoid
1786 unnecessarily alarming people when the test fails.
1788 * data/yacc.c (yyerrlab1): Move this label down, so that the
1789 parser does not discard the lookahead token if the user code
1790 invokes YYERROR. This change is required for POSIX conformance.
1792 * lib/error.c: Sync with gnulib.
1794 2002-11-22 Paul Eggert <eggert@twinsun.com>
1796 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
1797 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
1798 * lib/xmalloc.c: Likewise.
1800 2002-11-20 Paul Eggert <eggert@twinsun.com>
1802 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
1804 2002-11-20 Paul Eggert <eggert@twinsun.com>
1806 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
1807 should use `if (! x) abort ();' rather than `assert (x);', and
1808 anyway it's one less thing to worry about configuring.
1810 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
1811 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
1812 and replace all instances of assert with abort.
1813 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
1814 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
1816 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
1817 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
1818 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
1819 hash_find_entry, hash_rehash, hash_insert): Likewise.
1820 * src/conflicts.c (resolve_sr_conflict): Likewise.
1821 * src/lalr.c (set_goto_map, map_goto): Likewise.
1822 * src/nullable.c (nullable_compute): Likewise.
1823 * src/output.c (prepare_rules, token_definitions_output): Likewise.
1824 * src/reader.c (packgram, reader): Likewise.

1826 state_reduction_find): Likewise.
1827 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
1828 symbol_pack): Likewise.
1829 * src/tables.c (conflict_row, pack_vector): Likewise.
1830 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
1831 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
1832 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
1833 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
1835 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
1836 (ARGMATCH_CONSTRAINT): New macro.
1837 (ARGMATCH_ASSERT): Use it.
1839 * src/system.h (verify): New macro.
1840 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
1842 * src/tables.c (tables_generate): Likewise.
1844 * src/struniq.c (struniq_assert): Now returns void, and aborts
1845 if the assertion is false.
1846 (struniq_assert_p): Remove.
1847 * src/struniq.h: Likewise.
1849 2002-11-18 Paul Eggert <eggert@twinsun.com>
1851 * data/glr.c (yygetLRActions): Replace `yyindex' with
1852 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
1853 This fixes the regression with Sun ONE Studio 7 cc that I reported in
1854 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
1856 2002-11-18 Akim Demaille <akim@epita.fr>
1858 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
1860 From Tim Van Holder.
1862 2002-11-17 Paul Eggert <eggert@twinsun.com>
1864 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
1865 to "SyntaxError" for consistency with my 2002-11-15 change.
1867 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
1868 not define to {}, since this breaks the common use of `YYDPRINTF
1869 ((...));' if a single statement is desired (e.g. before `else').
1870 Work around GCC warnings by surrounding corresponding calls with
1872 (yyhasResolvedValue): Remove unused function.
1873 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
1875 (yyreportSyntaxError): Renamed from yyreportParseError.
1876 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
1878 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
1879 extern when possible. Remove unused initializations.

1883 Augment the similarity between GLR and LALR traces.
1885 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
1886 (YY_REDUCE_PRINT): New.
1887 (yyparse): Use them.
1888 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
1890 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
1891 state reached after the reduction/recovery, since...
1892 (yyparse, yyprocessOneStack): Report the state we are entering in.
1894 2002-11-16 Akim Demaille <akim@epita.fr>
1896 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
1897 Add support for --trace=skeleton.
1898 * src/scan-skel.l: %option debug.
1899 Scan strings of non-@ or \n instead of character by character.
1900 (scan_skel): Handle trace_skeleton.
1902 (@output_parser_name@, @output_header_name@): ``Restore'' their
1903 support (used to be M4 macros).
1904 * data/yacc.c: Quote larger chunks, a la glr.c.
1905 * data/lalr1.cc: Likewise.
1906 The header guards are no longer available, so use some other
1907 string than `YYLSP_NEEDED'.
1909 2002-11-16 Akim Demaille <akim@epita.fr>
1911 Make the ``Printers and Destructors'' test more verbose, taking
1912 `yacc.c''s behavior as (possibly wrong) reference.
1914 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
1915 instead of fprint on stdout.

1927 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
1928 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
1929 tests/action.at, tests/calc.at, tests/conflicts.at,
1930 tests/cxx-type.at, tests/regression.at:
1931 "parse error" -> "syntax error" for POSIX compatibility.
1932 "parsing stack overflow..." -> "parser stack overflow" so
1933 that code matches Bison documentation.
1935 2002-11-15 Akim Demaille <akim@epita.fr>
1937 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
1938 take two BRACED_CODE, not two string_content.
1939 Free the scanner's obstack when we are done.
1940 (code_content): New.
1941 * tests/calc.at: Adjust.
1942 * doc/bison.texinfo: Adjust.
1943 Also, make sure to include the `,' for these declarations.
1945 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
1947 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
1948 definition; avoids potential autoreconf problems.
1950 2002-11-15 Akim Demaille <akim@epita.fr>
1952 Always check the value returned by yyparse.
1954 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value

1959 returned by yyparse.
1961 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>

1966 2002-11-14 Paul Eggert <eggert@twinsun.com>
1968 * src/output.c (output_skeleton): Call xfopen instead of
1969 duplicating xfopen's body.
1971 Fix bugs reported by Nelson H. F. Beebe in
1972 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
1974 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
1975 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
1976 Group compiler. Instead, use "$CC -E bar.c". Include the .h
1977 file twice in the grammar, as an extra check.
1979 * tests/input.at (Torturing the Scanner): Surround the
1980 backslash-newline tests with "#if 0", to make it less likely that
1981 we'll run into compiler bugs. Bring back solitary \ inside
1982 comment, but add a closing comment to work around HP C bug. Don't
1983 test backslash-newline in C character constant.
1985 2002-11-14 Akim Demaille <akim@epita.fr>
1987 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
1988 status of the compiler.
1989 Calling `exit 1' is no longer needed.
1990 Reported by Nelson H. F. Beebe.

2005 2002-11-14 Akim Demaille <akim@epita.fr>
2007 * doc/bison.texinfo: Various formatting changes (alignments in
2008 samples, additional @group/@end group, GCS in samples.
2009 Use @deffn instead of simple @table to define the directives,
2010 macros, variables etc.
2012 2002-11-13 Paul Eggert <eggert@twinsun.com>
2014 Fix some bugs reported by Albert Chin-A-Young in
2015 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
2017 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
2018 -o c"; the HP C compiler chatters during compilation.
2019 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
2020 * tests/headers.at (export YYLTYPE): Likewise.
2022 * tests/input.at (Torturing the Scanner): Remove lines containing
2023 solitary backslashes, as they tickle a bug in the HP C compiler.
2025 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
2026 comments, since they're not portable. Use GNU coding style.
2028 2002-11-13 Akim Demaille <akim@epita.fr>
2030 * data/yacc.c: Leave bigger chunks of quoted text.
2031 (YYDSYMPRINTF): New.
2032 Use it to report symbol activities.
2033 * data/glr.c (YYDSYMPRINTF): New.
2036 2002-11-12 Paul Eggert <eggert@twinsun.com>
2040 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
2041 (yyglrReduce): Return yyok, not 0.
2042 This should avoid the enumerated-type warnings reported
2043 by Nelson H. F. Beebe in
2044 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
2046 * lib/bbitset.h (BITSET_INLINE): Remove.
2047 * lib/bitset.h [! BITSET_INLINE]: Remove.
2048 (bitset_set, bitset_reset, bitset_test): Rename local vars
2049 to avoid shadowing warnings by GCC.
2051 * data/glr.c (inline): Remove #define. It's the user's
2052 responsibility to #define it away, just like 'const'.
2053 This fixes one of the bugs reported by Nelson H. F. Beebe in
2054 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
2056 * Makefile.maint (po-check): Scan .l and .y files instead of the
2057 .c and the .h files that they generate. This fixes the bug
2058 reported by Tim Van Holder in:
2059 <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
2060 Look for N_ as well as for _. Try to avoid matching #define for
2062 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
2063 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
2064 * src/scan-gram.l: Revamp regular expressions so that " and '
2065 do not confuse xgettext.
2067 * src/struniq.h (struniq_new): Do not declare the return type
2068 to be 'const'; this violates the C standard.
2069 * src/struniq.c (struniq_new): Likewise.
2071 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
2073 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
2074 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
2077 2002-11-12 Akim Demaille <akim@epita.fr>
2079 * Makefile.maint: Sync with Autoconf:

2098 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
2099 Use it to test the GLR parser.
2101 2002-11-12 Akim Demaille <akim@epita.fr>
2103 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
2105 * data/glr.c (yystos): New.
2106 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
2108 (yyval): Don't define it, it is handled via M4.
2109 (yyrecoverParseError): Free verbosely the discarded symbols.
2110 * data/yacc.c (yysymprint): Remove, rather...
2111 (b4_yysymprint_generate): invoke.
2112 * data/c.m4 (b4_yysymprint_generate): New.
2113 Accept pointers as arguments, as opposed to the version from
2115 (b4_yydestruct_generate): Likewise.
2116 * tests/cations.at (Printers and Destructors): Use Bison directives
2117 instead of CPP macros.
2118 Don't rely on internal details.
2120 2002-11-12 Akim Demaille <akim@epita.fr>
2122 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
2123 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
2124 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
2125 it against YYEMPTY and so forth), work on yytoken (i.e., set
2126 it to YYEMPTY etc.).
2127 (yydestruct): Replace with a b4_yydestruct_generate invocation.
2128 (b4_symbol_actions): Remove.
2129 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
2130 for 0, end-of-input.
2132 2002-11-12 Akim Demaille <akim@epita.fr>
2134 * doc/bison.texinfo (Destructor Decl): New.
2136 2002-11-12 Akim Demaille <akim@epita.fr>
2138 * src/tables.c (tables_generate): Use free for pointers that
2139 cannot be NULL, not XFREE.
2140 (pack_vector): Use assert, not fatal, for bound violations.
2141 * src/state.c (state_new): Likewise.
2142 * src/reader.c (reader): Likewise.
2143 * src/lalr.c (set_goto_map): Likewise.
2144 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
2147 2002-11-12 Akim Demaille <akim@epita.fr>
2149 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
2151 * src/scan-gram.l (last_string): Is global to the file, not to
2153 * src/parse-gram.y (input): Don't append the epilogue here,
2154 (epilogue.opt): do it here, and free the scanner's obstack.
2155 * src/reader.c (epilogue_set): Rename as...
2156 (epilogue_augment): this.
2157 * data/c.m4 (b4_epilogue): Defaults to empty.
2159 2002-11-12 Akim Demaille <akim@epita.fr>
2161 * src/getargs.c (long_options): Remove duplicates.

2200 Don't free the input file name.
2202 2002-11-12 Akim Demaille <akim@epita.fr>
2204 * src/symtab.c (symbol_free): Remove dead deactivated code:

2215 2002-11-11 Paul Eggert <eggert@twinsun.com>
2217 Revamp to fix many (but not all) of the C- and M4-related quoting
2218 problems. Among other things, this fixes the Bison bug reported
2219 by Jan Hubicka when processing the Bash grammar; see:
2220 <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
2222 Use new @ escapes consistently. Represent brackets with @{ and @}
2223 rather than @<:@ and @:>@, since this works a bit better with dumb
2224 editors like vi. Represent @ with @@, since @ is now consistently
2225 an escape. Use @oline@ and @ofile@ rather than __oline__ and
2226 __ofile__, to avoid unexpected expansions. Similarly, use @output
2227 rather than #output.
2229 * data/c.m4 (b4_copyright): Omit file name from comment, since
2230 the file name could contain "*/".
2231 (b4_synclines_flag): Don't quote the 2nd argument; it should already
2232 be quoted. All uses changed.
2234 * data/glr.c: Use new @ escapes consistently.
2235 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
2236 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
2237 Remove, since they couldn't handle arbitrary characters in file
2239 * data/lalr1.cc: Likewise.
2240 * data/yacc.c: Likewise.
2242 * src/files.c (output_infix): Remove; all uses removed.
2243 * src/files.h: Likewise.
2245 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
2246 mishandled funny characters in file names, and anyway it isn't
2248 * data/yacc.c: Likewise.
2249 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
2251 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
2252 * data/yacc.c: Likewise.
2254 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
2256 (muscle_init): Quote filename as a C string.
2257 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
2258 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
2259 * src/output.c (escaped_file_name_output): New function.
2260 (prepare_symbols): Quote tokens for M4.
2261 (prepare): Don't insert output_infix, output_prefix,
2262 output_parser_name, output_header_name; this is now down by scan-skel.
2263 Insert skeleton as a C string.
2265 * src/output.c (user_actions_output, symbol_destructors_output,
2266 symbol_printers_output): Quote filenames for C and M4.
2267 * src/reader.c (prologue_augment, epilogue_set): Likewise.
2269 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
2270 escapes other than \\ and \'; this simplifies the code.
2271 (<SC_STRING>): Likewise, for \\ and \".
2272 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
2273 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
2274 Use new escapes @{ and @} for [ and ].
2276 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
2277 them with auto vars.
2278 Switch to new escape scheme, where @ is the escape character uniformly.
2279 Abort if a stray escape character is found. Avoid unbounded input
2280 buffer when parsing non-escaped text.
2282 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
2283 __oline__, #output, $@, and @{ do not have unintended meanings.
2285 2002-11-09 Paul Eggert <eggert@twinsun.com>
2287 Fix the test failure due to GCC warnings described in
2288 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
2289 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
2290 evaluate to 0 if it's impossible for NINF to be in the respective
2292 (yygetLRActions, yyrecoverParseError): Use them.
2294 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
2295 counted in the token inserted at end of file. Now takes
2296 location_t *, not location_t, so that the location can be
2297 adjusted. All uses changed.
2299 * tests/regression.at (Invalid inputs): Adjust wording in
2300 diagnostic to match the new behavior.
2302 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
2303 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
2304 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
2305 abort ();'. This reduces the runtime of the "Many lookaheads"
2306 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
2309 2002-11-07 Paul Eggert <eggert@twinsun.com>
2311 * src/parse-gram.y (CHARACTER): Remove unused token.
2314 * src/scan-gram.l: Remove stack option. We no longer use the
2315 stack, since the stack was never deeper than 1; instead, use the
2316 new auto var c_context to record the stacked value.
2318 Remove nounput option. At an unexpected end of file, we now unput
2319 the minimal input necessary to end cleanly; this simplifies the
2322 Avoid unbounded token sizes where this is easy.
2324 (unexpected_end_of_file): New function.
2325 Use it to systematize the error message on unexpected EOF.
2326 (last-string): Now auto, not static.
2327 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
2328 (scanner_last_string_free): Remove; not used.
2329 (percent_percent_count): Move decl to just before use.
2330 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
2331 not the (never otherwised-used) CHARACTER.
2333 2002-11-07 Akim Demaille <akim@epita.fr>
2335 Let yyerror always receive the msg as last argument, so that
2336 yyerror can be variadic.
2338 * data/yacc.c (b4_yyerror_args): New.
2339 Use it when calling yyerror.
2340 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
2341 Use it when calling yyerror.
2342 * doc/bison.texinfo (Error Reporting): Adjust.
2343 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
2344 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
2346 2002-11-06 Akim Demaille <akim@epita.fr>
2348 #line should have quoted strings.
2349 Ideally, this should be done by m4_quotearg.
2351 * src/scan-skel.l: Include quotearg.h.
2353 * src/output.c (symbol_printers_output)
2354 (symbol_destructors_output): Quote the file name.
2356 2002-11-06 Akim Demaille <akim@epita.fr>
2358 * tests/regression.at (Invalid inputs): Adjust to the recent
2361 2002-11-06 Akim Demaille <akim@epita.fr>
2364 Reported by Jim Kent.
2366 * data/c.m4 (b4_syncline): New.

2402 as POSIX 1003.1-2001 requires.
2403 * src/system.h (IF_LINT): New macro, taken from coreutils.
2404 * configure.ac: Define "lint" if --enable-gcc-warnings.
2406 2002-11-05 Akim Demaille <akim@epita.fr>
2408 * src/scan-gram.l: When it starts with `%', complain about the

2427 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
2429 * src/scan-gram.l: Use [\'] instead of ['] to pacify
2432 Use quote, not quote_n since LOCATION_PRINT no longer uses the
2435 2002-11-03 Paul Eggert <eggert@twinsun.com>
2437 * src/reader.c (get_merge_function, grammar_current_rule_check):
2438 Use consistent diagnostics for reporting type name clashes.

2454 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
2455 b4_user_formals and b4_user_args.
2456 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
2457 (yyreportAmbiguity): When using a pure parser, also need
2458 the location, and the parse-params.
2460 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
2461 When using a pure parser, also need the parse-params.
2463 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
2464 (%pure-parser + %parse-param) LALR and GLR parsers.
2465 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
2466 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,

2484 2002-11-03 Paul Eggert <eggert@twinsun.com>
2486 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
2487 to count columns correctly, and to check for invalid inputs.
2489 Use mbsnwidth to count columns correctly. Account for tabs, too.
2491 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
2492 (extend_location): New function.
2495 Handle CRLF in C code rather than in Lex code.

2499 Scan UCNs, even though we don't fully handle them yet.
2500 (convert_ucn_to_byte): New function.
2502 Handle backslash-newline correctly in C code.
2503 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
2504 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;

2508 YY_STEP after space, newline, vertical-tab.
2509 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
2511 (letter, id): Don't assume ASCII; e.g., spell out a-z.
2513 ({int}, handle_action_dollar, handle_action_at): Check for integer
2516 (YY_STEP): Omit trailing semicolon, so that it's more like C.
2518 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
2519 as well as \000. Check for UCHAR_MAX, not 255.
2520 Allow \x with an arbitrary positive number of digits, as in C.
2521 Check for overflow here.
2522 Allow \? and UCNs, for compatibility with C.
2524 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
2525 with quote slot used by complain_at.
2527 * tests/input.at: Add tests for backslash-newline, m4 quotes
2528 in symbols, long literals, and funny escapes in strings.
2530 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
2531 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.

2544 2002-11-02 Paul Eggert <eggert@twinsun.com>
2546 * src/reader.c: Don't include quote.h; not needed.

2553 * src/output.c (prepare_symbols): When printing token names,
2554 escape "[" as "@<:@" and likewise for "]".
2556 * src/system.h (errno): Remove declaration, as we are now
2557 assuming C89 or better, and C89 guarantees errno.
2559 2002-10-30 Paul Eggert <eggert@twinsun.com>
2561 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
2562 Check for close failures.
2563 * src/files.h (xfclose): Return void, not int, since it always
2565 * src/files.c (xfclose): Likewise. Report I/O error if ferror
2567 * src/output.c (output_skeleton): Use xfclose rather than fclose
2568 and ferror. xfclose now checks ferror.
2570 * data/glr.c (YYLEFTMOST_STATE): Remove.
2571 (yyreportTree): Use a stack-based leftmost state. This avoids
2572 our continuing battles with bogus warnings about initializers.
2574 2002-10-30 Akim Demaille <akim@epita.fr>
2576 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

2589 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
2590 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
2591 we use malloc. Don't assume 'A' through 'Z' are contiguous.
2592 Don't assume strdup exists; POSIX says its an XSI extension.
2593 Check for buffer overflow on input.
2595 2002-10-24 Akim Demaille <akim@epita.fr>
2597 * src/output.c (output_skeleton): Don't disable M4sugar comments
2598 too soon: it results in comments being expanded.
2599 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
2602 2002-10-24 Akim Demaille <akim@epita.fr>
2604 * data/yacc.c (m4_int_type): New.
2605 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
2606 char' as only yacc.c wants K&R portability.

2608 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
2609 Reported by Quoc Peyrot.
2611 2002-10-23 Paul Eggert <eggert@twinsun.com>
2613 * src/main.c (main): With --trace=time, report times even if a
2614 non-fatal error occurs. Formerly, the times were reported in some
2615 such cases but not in others.
2616 * src/reader.c (reader): Just return if a complaint has been issued,
2617 instead of exiting, so that 'main' can report times.
2619 2002-10-22 Akim Demaille <akim@epita.fr>
2621 * src/system.h: Include sys/types.
2622 Reported by Bert Deknuydt.
2624 2002-10-23 Paul Eggert <eggert@twinsun.com>
2626 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.

2631 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
2632 decl; not needed any more.
2633 * src/main.c (main): Use return to exit, undoing yesterday's change.
2634 The last OS that we could find where this wouldn't work is
2635 SunOS 3.5, and that's too old to worry about now.
2637 * data/glr.c (struct yyltype): Define members even when not
2638 doing locations. This is more consistent with yacc.c, and it
2639 works around the following bug reports:
2640 http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
2641 http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
2643 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
2644 @acronym consistently. Standardize on "Yacc" instead of "YACC",
2645 "Algol" instead of "ALGOL". Give a bit more history about BNF.
2647 2002-10-22 Akim Demaille <akim@epita.fr>
2651 2002-10-21 Paul Eggert <eggert@twinsun.com>
2653 Be consistent about 'bool'; the old code used an enum in one
2654 module and an int in another, and this violates the C standard.
2655 * m4/stdbool.m4: New file, from coreutils 4.5.3.
2656 * configure.ac (AC_HEADER_STDBOOL): Add.
2657 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.

2661 with ../lib/hash.c. All uses changed.
2663 * src/complain.c (warning_issued): Renamed from warn_message_count,
2664 so that we needn't worry about integer overflow (!).
2665 Now of type bool. All uses changed.
2666 (complaint_issued): Renamed from complain_message_count; likewise.
2668 * src/main.c (main): Use exit to exit with failure.
2670 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
2671 rather than 1 and 0.
2672 * src/main.c (main): Likewise.
2673 * src/getargs.c (getargs): Likewise.
2674 * src/reader.c (reader): Likewise.
2676 * src/getarg.c (getargs): Remove duplicate code for
2677 "Try `bison --help'".
2679 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
2680 What was that "2" for?
2682 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
2683 * src/getargs.c (usage): Likewise.
2685 * src/getargs.c (getargs): When there are too few operands, report
2686 the last one. When there are too many, report the first extra
2687 one. This is how diffutils does it.
2689 2002-10-20 Paul Eggert <eggert@twinsun.com>
2691 Remove K&R vestiges.
2692 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
2693 * src/complain.c (VA_START): Remove. Assume prototypes.

2696 fatal): Assume prototypes.
2697 * src/complain.h: Assume prototypes.
2698 * src/system.h (PARAMS): Remove.
2699 Include <limits.h> unconditionally, since it's guaranteeed even
2700 for a freestanding C89 compiler.
2701 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
2702 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
2704 2002-10-20 Akim Demaille <akim@epita.fr>

2721 (b4_c_ansi_function_decl): New.
2722 Change the interpretation of the arguments: before `int, foo', now
2724 * data/yacc.c (yyparse): Prototype and define thanks to these.
2725 Adjust b4_c_function_def uses.
2726 * data/glr.c (yyparse): Likewise, but ANSI only.
2728 2002-10-20 Akim Demaille <akim@epita.fr>
2730 * src/output.c (prepare): Move the definition of `tokens_number',
2731 `nterms_number', `undef_token_number', `user_token_number_max'

2735 (prepare_symbols): this.
2736 (prepare): Move the definition of `rules_number' to...
2737 (prepare_rules): here.
2738 (prepare): Move the definition of `last', `final_state_number',
2739 `states_number' to...

2760 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
2763 2002-10-19 Paul Eggert <eggert@twinsun.com>
2765 Do not create a temporary file, as that involves security and
2766 cleanup headaches. Instead, use a pair of pipes.
2767 Derived from a suggestion by Florian Krohm.
2768 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
2769 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.

2783 (scan_skel): New function, to be used in place of m4_invoke.
2784 Read from stream rather than file.
2786 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
2787 float, as this generates a warning on Solaris 8 + GCC 3.2 with
2788 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
2789 this generates a more-accurate value anyway.
2791 * lib/timevar.c (timervar_accumulate): Rename locals to
2792 avoid confusion with similarly-named more-global.
2793 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
2795 * src/output.c (prepare): Use xstrdup to convert char const *
2796 to char *, to avoid GCC warning.
2798 2002-10-19 Akim Demaille <akim@epita.fr>
2800 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,

2803 * data/yacc.c (YYLEX): Pass a yylex return type to
2806 2002-10-19 Akim Demaille <akim@epita.fr>
2808 Prototype support of %lex-param and %parse-param.
2810 * src/parse-gram.y: Add the definition of the %lex-param and
2811 %parse-param tokens, plus their rules.
2812 Drop the `_' version of %glr-parser.
2814 * src/scan-gram.l (INITIAL): Scan them.
2815 * src/muscle_tab.c: Comment changes.

2832 * src/getargs.c (usage): Take status as argument and exit
2834 Report the traditional `Try ... --help' message when status != 0.
2835 (usage, version): Don't take a FILE * as arg, it is pointless.
2836 (getargs): When there is an incorrect number of arguments, make it
2837 an error, and report it GNUlically thanks to `usage ()'.

2841 * data/glr.c (yyreportParseError): Don't assume that sprintf
2842 yields the length of the printed string, as this is not true
2843 on SunOS 4.1.4. Reported by Peter Klein.
2845 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
2846 * tests/conflicts.at (%nonassoc and eof): Likewise.
2847 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
2849 2002-10-17 Akim Demaille <akim@epita.fr>
2851 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
2852 * src/getargs.c (trace_types, trace_args): Adjust.
2853 * src/reader.c (grammar_current_rule_prec_set)
2854 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
2855 Standardize error messages.
2857 (reader): Use trace_flag to enable scanner/parser debugging,
2858 instead of an adhoc scheme.
2859 * src/scan-gram.l: Remove trailing debugging code.

2863 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
2866 * NEWS: Officially drop support for building Bison with K&R C,
2867 since it didn't work anyway and it's not worth worrying about.
2868 * Makefile.maint (wget_files): Remove ansi2knr.c.
2869 (ansi2knr.c-url_prefix): Remove.
2870 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.

2874 2002-10-15 Paul Eggert <eggert@twinsun.com>
2876 Stop using the "enum_" trick for K&R-style function definitions;
2877 it confused me, and I was the author! Instead, assume that people
2878 who want to use K&R C compilers (when using these modules in GCC,
2879 perhaps?) will run ansi2knr.
2881 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
2882 All uses of "enum_" changed to "enum ".

2971 tests/cxx-type.at, tests/headers.at, tests/input.at,

2973 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
2974 so that the tests still work even if POSIXLY_CORRECT is set.
2975 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
2977 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
2978 for portability to K&R hosts. Fix typo: signed char is guaranteed
2979 only to 127, not to 128.
2980 * data/glr.c (yysigned_char): New type.
2981 * data/yacc.c (yysigned_char): Likewise.
2982 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
2984 2002-10-13 Paul Eggert <eggert@twinsun.com>
2986 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
2987 true due to limited range of data type" warning from GCC.
2989 * data/c.m4 (b4_token_defines): Protect against double-inclusion
2990 by wrapping enum yytokentype's definition inside #ifndef
2991 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
2993 2002-10-13 Akim Demaille <akim@epita.fr>
2995 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
2996 Un yy- yyrhs to avoid the name clash with the global YYRHS.
2998 2002-10-13 Akim Demaille <akim@epita.fr>
3000 * Makefile.maint: Update from Autoconf 2.54.
3001 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
3003 2002-10-13 Akim Demaille <akim@epita.fr>

3011 Let nondeterministic skeletons be usable with deterministic
3014 With the patch, GAWK compiled by GCC without -O2 passes its test
3015 suite using a GLR parser driven by LALR tables. It fails with -O2
3016 because `struct stat' gives two different answers on my machine:
3017 88 (definition of an auto var) and later 96 (memset on this var).
3018 Hence the stack is badly corrumpted. The headers inclusion is to
3019 blame: if I move the awk.h inclusion before GLR's system header
3020 inclusion, the two struct stat have the same size.
3022 * src/tables.c (pack_table): Always create conflict_table.
3023 (token_actions): Always create conflict_list.
3024 * data/glr.c (YYFLAG): Remove, unused.
3026 2002-10-13 Akim Demaille <akim@epita.fr>
3028 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
3030 (VALGRIND, GXX): New.
3031 * tests/atlocal.in (CFLAGS): Use O0FLAGS.

3039 * data/glr.c: Formatting changes.
3040 Tweak some trace messages to match yacc.c's.
3042 2002-10-13 Akim Demaille <akim@epita.fr>
3044 GLR parsers sometimes raise parse errors instead of performing the
3046 Reported by Charles-Henry de Boysson.
3048 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
3049 check the length of the traces when %glr.
3050 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
3052 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
3054 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
3055 (yyltype): Remove the yy prefix from the member names.
3056 (yytable): Complete its comment.
3057 (yygetLRActions): Map error action number from YYTABLE from
3059 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
3060 (which was a bug: it should have been YYTABEL_NINF, and yet it was
3061 not satisfying as we could compare an YYACTION computed from
3062 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
3063 only value for error actions.
3064 (yyreportParseError): In verbose parse error messages, don't issue
3065 `error' in the list of expected tokens.
3066 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
3067 next action to perform to match glr.c's decoding.
3068 (yytable): Complete its comment.

3072 Fix problem reported by Henrik Grubbstroem in

3074 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
3075 because the Bison parser reads the second action before reducing
3077 * src/scan-gram.l (rule_length): New static var.
3078 Use it to keep track of the rule length in the scanner, since
3079 we can't expect the parser to be in lock-step sync with the scanner.
3080 (handle_action_dollar, handle_action_at): Use this var.
3081 * tests/actions.at (Exotic Dollars): Test for the problem.
3083 2002-10-12 Paul Eggert <eggert@twinsun.com>

3087 Include <sys/time.h> when checking for clock_t and struct tms.
3088 Use same include order as source.
3089 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
3090 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
3092 * lib/timevar.c: Update copyright date and clarify comments.
3093 (get_time) [IN_GCC]: Keep the GCC version for reference.
3095 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
3096 GCC version as of today, then merge Bison's changes.
3097 Change "GCC" to "Bison" in copyright notice. timevar.def's
3098 author is Akim, so change that too.
3100 * src/reader.c (grammar_current_rule_check):
3101 Don't worry about the default action if $$ is untyped.
3102 Prevents bogus warnings reported by Jim Gifford in
3103 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
3105 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
3106 * data/glr.c, data/lalr1.cc, data/yacc.c:
3107 Output token definitions before the first part of user declarations.
3108 Fixes compatibility problem reported by Jim Gifford for kbd in
3109 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.

3135 * lib/lbitset.c: Likewise.
3137 * lib/abitset.c (abitset_bytes): Return a size that is aligned
3138 properly for vectors of objects. Do not assume that adding a

3140 properly aligned for the whole union.
3141 * lib/bitsetv.c (bitsetv_alloc): Likewise.

3230 2002-10-06 Paul Eggert <eggert@twinsun.com>
3232 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
3233 the same width as int. This reapplies a hunk of the 2002-08-12 patch
3234 <http://mail.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
3235 which was inadvertently undone by the 2002-09-30 patch.

3249 the portable Standard C character set.
3251 The GNU coding standard says CFLAGS and YFLAGS are reserved
3252 for the installer to set.

3598 this is a GCC extension and is not portable to other compilers.

3736 Let --trace have arguments.

3739 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
3740 (long_options, short_options): --trace/-T takes an optional
3742 Change all the uses of trace_flag to reflect the new flags.
3743 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
3745 Strengthen `stage' portability.
3747 * m4/stage.m4 (BISON_PREREQ_STAGE): New.

3834 token_translations instead of `0'.
3835 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
3837 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
3838 for the time being: %locations ought to provide it to yyerror.
3840 2002-07-25 Akim Demaille <akim@epita.fr>
3842 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

6300 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
6302 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
6304 2002-01-20 Marc Autret <marc@gnu.org>
6306 * src/files.c (compute_output_file_names): Fix
6308 2002-01-20 Marc Autret <marc@gnu.org>
6310 * tests/output.at: New test.
6311 * src/files.c (compute_base_names): Don't map extensions when
6312 the YACC flag is set, use defaults.
6313 Reported by Evgeny Stambulchik.
6315 2002-01-20 Marc Autret <marc@gnu.org>
6317 * src/system.h: Need to define __attribute__ away for non-GCC
6318 compilers as well (i.e. the vendor C compiler).
6319 Suggested by Albert Chin-A-Young.
6321 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
6323 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
6324 canonical definition.
6325 * src/system.h: Use the canonical definition for PARAMS (avoids
6326 a conflict with the macro from lib/hash.h).
6328 2002-01-11 Akim Demaille <akim@epita.fr>
6330 * configure.in: Use AC_FUNC_STRNLEN.
6331 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
6333 2002-01-09 Akim Demaille <akim@epita.fr>
6335 * src/files.c, src/files.h (output_infix): New.
6336 (tab_extension): Remove.
6337 (compute_base_names): Compute the former, drop the latter.
6338 * src/output.c (prepare): Insert the muscles `output-infix', and
6340 * src/parse-skel.y (string, string.1): New.
6341 (section.header): Use it.
6342 (section.yacc): Remove.
6343 (prefix): Remove too.
6344 * src/scan-skel.l: Adjust.
6345 * src/bison.simple, src/bison.hairy: Adjust.
6347 2002-01-09 Akim Demaille <akim@epita.fr>
6349 * configure.in (WERROR_CFLAGS): Compute it.
6350 * src/Makefile.am (CFLAGS): Pass it.
6351 * tests/atlocal.in (CFLAGS): Idem.
6352 * src/files.c: Fix a few warnings.
6353 (get_extension_index): Remove, unused.
6355 2002-01-08 Akim Demaille <akim@epita.fr>
6357 * src/getargs.c (AS_FILE_NAME): New.
6358 (getargs): Use it to convert DOSish file names.
6359 * src/files.c (base_name): Rename as full_base_name to avoid
6360 clashes with `base_name ()'.
6361 (filename_split): New.
6362 (compute_base_names): N-th rewrite, using filename_split.
6364 2002-01-08 Akim Demaille <akim@epita.fr>
6366 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
6367 New, stolen from the Fileutils 4.1.
6368 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
6369 * configure.in: Check for the presence of memrchr, and of its
6372 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
6374 * lib/hash.h (__P): Added definition for this macro.
6375 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
6376 BUILT_SOURCES, to ensure they are generated first.
6377 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
6378 %error-verbose to allow bootstrapping with bison 1.30x.
6380 2002-01-06 Akim Demaille <akim@epita.fr>
6382 * src/reader.c (parse_braces): Don't fetch the next char, the
6383 convention is to fetch on entry.
6384 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
6385 'switch' without a following semicolon.
6386 * tests/regression.at (braces parsing): New.
6388 2002-01-06 Akim Demaille <akim@epita.fr>
6390 Bison is dead wrong in its RR conflict reports.
6392 * tests/torture.at (GNU Cim Grammar): New.
6393 * src/conflicts.c (count_rr_conflicts): Fix.
6395 2002-01-06 Akim Demaille <akim@epita.fr>
6397 Creating package.m4 from configure.ac causes too many problems.
6399 * tests/Makefile.am (package.m4): Create it by hand,
6400 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
6402 2002-01-06 Akim Demaille <akim@epita.fr>
6404 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
6407 2002-01-04 Paul Eggert <eggert@twinsun.com>
6409 * doc/bison.texinfo (Debugging):
6410 Remove YYSTDERR; it's no longer defined or used.
6411 Also, s/cstdio.h/cstdio/.
6413 2002-01-03 Akim Demaille <akim@epita.fr>
6415 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
6417 2002-01-03 Akim Demaille <akim@epita.fr>
6419 * src/parse-skel.y (process_skeleton): Don't bind the parser's
6420 tracing code to --trace, wait for a better --trace option, with
6423 2002-01-03 Akim Demaille <akim@epita.fr>
6425 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
6426 The ISO C++ standard is extremely clear about it: stderr is
6427 considered a macro, not a regular symbol (see table 94 `Header
6428 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
6429 Therefore std:: does not apply to it. It still does with fprintf.
6430 Also, s/cstdio.h/cstdio/.
6432 2002-01-03 Akim Demaille <akim@epita.fr>
6434 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
6435 for non system headers.
6437 2002-01-02 Akim Demaille <akim@epita.fr>
6439 Equip the skeleton chain with location tracking, runtime trace,
6440 pure parser and scanner.
6442 * src/parse-skel.y: Request a pure parser, locations, and prefix
6444 (%union): Having several members with the same type does not help
6445 type mismatches, simplify.
6446 (YYPRINT, yyprint): New.
6447 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
6450 * src/scan-skel.l: Adjust to these changes.
6451 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
6452 (LOCATION_PRINT, skel_control_t): New.
6454 2001-12-30 Akim Demaille <akim@epita.fr>
6456 * src/parse-skel.y: Get rid of the shift/reduce conflict:
6457 replace `gb' with BLANKS.
6458 * src/scan-skel.l: Adjust.
6460 2001-12-30 Akim Demaille <akim@epita.fr>
6462 * src/system.h: We don't need nor want bcopy.
6463 Throw away MS-DOS crap: we don't need getpid.
6464 * configure.in: We don't need strndup. It was even causing
6465 problems: because Flex includes the headers *before* us,
6466 _GNU_SOURCE is not defined by config.h, and therefore strndup was
6468 * lib/xstrndup.c: New.
6469 * src/scan-skel.l: Use it.
6470 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
6471 * src/parse-skel.y: Use %directives instead of #defines.
6473 2001-12-30 Akim Demaille <akim@epita.fr>
6475 * src/skeleton.h: New.
6476 * src/output.c (output_parser, output_master_parser): Remove, dead
6478 * src/output.h (get_lines_number, actions_output, guards_output)
6479 (token_definitions_output): Prototype them.
6480 * src/parse-skel.y: Add the license notice.
6481 Include output.h and skeleton.h.
6482 (process_skeleton): Returns void, and takes a single parameter.
6483 * src/scan-skel.l: Add the license notice.
6485 Don't use %option yylineno: it seems that then Flex imagines
6486 REJECT has been used, and therefore it won't reallocate its
6487 buffers (which makes no other sense to me than a bug). It results
6488 in warnings for `unused: yy_flex_realloc'.
6490 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
6492 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
6493 (MUSCLE_INSERT_PREFIX): ...to there.
6494 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
6495 (MUSCLE_INSERT_PREFIX): Move from here...
6497 * src/bison.hairy: Add a section directive. Put braces around muscle
6498 names. This parser skeleton is still broken, but Bison should not
6499 choke on a bad muscle 'syntax'.
6500 * src/bison.simple: Add a section directive. Put braces around muscle
6503 * src/files.h (strsuffix, stringappend): Add declarations.
6504 (tab_extension): Add declaration.
6505 (short_base_name): Add declaration.
6507 * src/files.c (strsuffix, stringappend): No longer static. These
6508 functions are used in the skeleton parser.
6509 (tab_extension): New.
6510 (compute_base_names): Use the computations done in this function
6511 to guess if the generated parsers should have '.tab' in their
6513 (short_base_name): No longer static.
6515 * src/output.c (output_skeleton): New.
6516 (output): Disable call to output_master_parser, and give a try to
6517 a new skeleton handling system.
6518 (guards_output, actions_output): No longer static.
6519 (token_definitions_output, get_lines_number): No longer static.
6521 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
6523 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
6526 * src/parse-skel.y: New file.
6527 * src/scan-skel.l: New file.
6529 2001-12-29 Akim Demaille <akim@epita.fr>
6531 %name-prefix is broken.
6533 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
6534 Adjust all dependencies.
6535 * tests/headers.at (export YYLTYPE): Strengthen this test: use
6538 Renaming yylval but not yylloc is not consistent. Now we do.
6540 * src/bison.simple: Prefix yylloc if used.
6541 * doc/bison.texinfo (Decl Summary): Document that.
6543 2001-12-29 Akim Demaille <akim@epita.fr>
6545 * doc/bison.texinfo: Promote `%long-directive' over
6547 Remove all references to fixed-output-files, yacc is enough.
6549 2001-12-29 Akim Demaille <akim@epita.fr>
6551 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
6552 user prologue. These are defaults.
6553 * tests/actions.at (Mid-rule actions): Make sure the user can
6554 define YYDEBUG and YYERROR_VERBOSE.
6556 2001-12-29 Akim Demaille <akim@epita.fr>
6558 * src/output.c (header_output): Don't forget to export YYLTYPE and
6560 * tests/headers.at (export YYLTYPE): New, make sure it does.
6561 * tests/regression.at (%union and --defines, Invalid CPP headers):
6563 * tests/headers.at: here.
6565 2001-12-29 Akim Demaille <akim@epita.fr>
6567 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
6569 2001-12-29 Akim Demaille <akim@epita.fr>
6571 * tests/actions.at (Mid-rule actions): Output on a single line
6574 2001-12-29 Akim Demaille <akim@epita.fr>
6576 * doc/bison.texinfo: Formatting changes.
6578 2001-12-29 Akim Demaille <akim@epita.fr>
6580 Don't store the token defs in a muscle, just be ready to output it
6581 on command. Now possible via `symbols'. Fixes a memory leak.
6583 * src/output.c (token_definitions_output): New.
6584 (output_parser, header_output): Use it.
6585 * src/reader.c (symbols_save): Remove.
6587 2001-12-29 Akim Demaille <akim@epita.fr>
6589 * src/bison.simple: Do not provide a default for YYSTYPE and
6590 YYLTYPE before the user's prologue. Otherwise it's hardly... a
6593 2001-12-29 Akim Demaille <akim@epita.fr>
6595 Mid-rule actions are simply... ignored!
6597 * src/reader.c (readgram): Be sure to attach mid-rule actions to
6598 the empty-rule associated to the dummy symbol, not to the host
6600 * tests/actions.at (Mid-rule actions): New.
6602 2001-12-29 Akim Demaille <akim@epita.fr>
6606 * src/reader.c (reader): Free grammar.
6608 2001-12-29 Akim Demaille <akim@epita.fr>
6612 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
6613 since it allocates it for each state, although only one is needed.
6614 (allocate_storage): Do it here.
6616 2001-12-29 Akim Demaille <akim@epita.fr>
6618 * src/options.h, src/options.c (create_long_option_table): Rename
6620 (long_option_table_new): this, with a clearer prototype.
6621 (percent_table): Remove, unused,
6622 * src/getargs.c (getargs): Adjust.
6624 2001-12-29 Akim Demaille <akim@epita.fr>
6626 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
6627 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
6630 2001-12-29 Akim Demaille <akim@epita.fr>
6632 * src/lalr.c (build_relations): Rename `states' as `states1'.
6633 Sorry, I don't understand exactly what it is, no better name...
6635 2001-12-29 Akim Demaille <akim@epita.fr>
6637 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
6638 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
6639 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
6642 2001-12-29 Akim Demaille <akim@epita.fr>
6644 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
6647 2001-12-29 Akim Demaille <akim@epita.fr>
6649 * src/reader.c, src/reader.h (user_toknums): Remove.
6650 Adjust all users to use symbols[i]->user_token_number.
6652 2001-12-29 Akim Demaille <akim@epita.fr>
6654 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
6655 Adjust all users to use symbols[i]->prec or ->assoc.
6657 2001-12-29 Akim Demaille <akim@epita.fr>
6659 * src/reader.c, src/reader.h (tags): Remove.
6660 Adjust all users to use symbols[i]->tag.
6662 2001-12-29 Akim Demaille <akim@epita.fr>
6664 * src/gram.h, src/gram.c (symbols): New, similar to state_table
6666 * src/reader.c (packsymbols): Fill this table.
6668 * src/conflicts.c (resolve_sr_conflict): Adjust.
6669 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
6671 Use symbols[i]->tag instead of tags[i].
6673 2001-12-29 Akim Demaille <akim@epita.fr>
6675 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
6676 In addition, put a comment in there, to replace...
6677 * tests/regression.at (%union and C comments): Remove.
6679 2001-12-29 Akim Demaille <akim@epita.fr>
6681 * tests/regression.at (Web2c Actions): Blindly move the actual
6682 output as expected output. The contents *seem* right to me, but I
6683 can't pretend reading perfectly parser tables... Nonetheless, all
6684 the other tests pass correctly, the table look OK, even though the
6685 presence of `$axiom' is to be noted: AFAICS it is useless (but
6688 2001-12-29 Akim Demaille <akim@epita.fr>
6690 * src/reader.c (readgram): Don't add the rule 0 if there were no
6691 rules read. In other words, add it _after_ having performed
6692 grammar sanity checks.
6693 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
6695 2001-12-29 Akim Demaille <akim@epita.fr>
6697 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
6698 visible, and some states have now a different number.
6700 2001-12-29 Akim Demaille <akim@epita.fr>
6702 * src/reader.c (readgram): Bind the initial rule's lineno to that
6704 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
6705 (Solved SR Conflicts): Adjust rule 0's line number.
6707 2001-12-29 Akim Demaille <akim@epita.fr>
6709 Fix the `GAWK Grammar' failure.
6711 * src/LR0.c (final_state): Initialize to -1 so that we do compute
6712 the reductions of the first state which was mistakenly confused
6713 with the final state because precisely final_state was initialized
6715 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
6716 now noticed by Bison.
6717 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
6718 have a reduction on $default.
6720 2001-12-29 Akim Demaille <akim@epita.fr>
6722 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
6724 * src/closure.c (print_closure): Likewise.
6725 * src/derives.c (print_derives): Likewise.
6726 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
6729 2001-12-29 Akim Demaille <akim@epita.fr>
6731 * src/lalr.c (lookaheads_print): New.
6732 (lalr): Call it when --trace-flag.
6733 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
6736 2001-12-29 Akim Demaille <akim@epita.fr>
6738 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
6739 when walking through ritem, even via rule->rhs.
6740 * src/reduce.c (dump_grammar, useful_production, reduce_output)
6741 (useful_production, useless_nonterminals): Likewise.
6742 (reduce_grammar_tables): Likewise, plus update nritems.
6743 * src/nullable.c (set_nullable): Likewise.
6744 * src/lalr.c (build_relations): Likewise.
6745 * tests/sets.at (Nullable): Adjust.
6746 Fortunately, now, the $axiom is no longer nullable.
6748 2001-12-29 Akim Demaille <akim@epita.fr>
6750 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
6752 * src/gram.c (ritem_longest_rhs): Likewise.
6753 * src/reduce.c (nonterminals_reduce): Likewise.
6754 * src/print_graph.c (print_graph): Likewise.
6755 * src/output.c (output_rule_data): Likewise.
6756 * src/nullable.c (set_nullable): Likewise.
6758 2001-12-29 Akim Demaille <akim@epita.fr>
6760 * src/output.c: Comment changes.
6762 2001-12-27 Paul Eggert <eggert@twinsun.com>
6764 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
6765 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
6766 Sparc, as they were causing more porting problems than the
6767 (minor) performance improvement was worth.
6769 Also, catch up with 1.31's YYSTD.
6771 2001-12-27 Akim Demaille <akim@epita.fr>
6773 * src/output.c (output_gram): Rely on nritems, not the
6774 0-sentinel. See below.
6775 Use -1 as separator, not 0.
6776 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
6777 Rely on -1 as separator in yyrhs, instead of 0.
6778 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
6779 twice `Now at end of input', therefore there are two lines less to
6782 2001-12-27 Akim Demaille <akim@epita.fr>
6784 * tests/regression.at (Unresolved SR Conflicts):
6785 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
6788 2001-12-27 Akim Demaille <akim@epita.fr>
6790 * src/LR0.c (new_state): Recognize the final state by the fact it
6791 is reached by eoftoken.
6792 (insert_start_shifting_state, insert_eof_shifting_state)
6793 (insert_accepting_state, augment_automaton): Remove, since now
6794 these states are automatically computed from the initial state.
6795 (generate_states): Adjust.
6796 * src/print.c: When reporting a rule number to the user, substract
6797 1, so that the axiom rule is rule 0, and the first user rule is 1.
6798 * src/reduce.c: Likewise.
6799 * src/print_graph.c (print_core): For the time being, just as for
6800 the report, depend upon --trace-flags to dump the full set of
6802 * src/reader.c (readgram): Once the grammar read, insert the rule
6803 0: `$axiom: START-SYMBOL $'.
6804 * tests/set.at: Adjust: rule 0 is now displayed, and since the
6805 number of the states has changed (the final state is no longer
6806 necessarily the last), catch up.
6808 2001-12-27 Akim Demaille <akim@epita.fr>
6810 Try to make the use of the eoftoken valid. Given that its value
6811 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
6812 is used instead of > 0 where appropriate, (ii), depend upon nritems
6813 instead of the 0-sentinel.
6815 * src/gram.h, src/gram.c (nritems): New.
6816 Expected to be duplication of nitems, but for the time being...
6817 * src/reader.c (packgram): Assert nritems and nitems are equal.
6818 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
6819 * src/closure.c (print_closure, print_fderives): Likewise.
6820 * src/gram.c (ritem_print): Likewise.
6821 * src/print.c (print_core, print_grammar): Likewise.
6822 * src/print_graph.c: Likewise.
6824 2001-12-27 Akim Demaille <akim@epita.fr>
6826 * src/main.c (main): If there are complains after grammar
6827 reductions, then output the report anyway if requested, then die.
6828 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
6829 * src/reader.c (eoftoken): New.
6830 (parse_token_decl): If the token being defined has value `0', it
6832 (packsymbols): No longer hack `tags' to insert `$' by hand.
6833 Be sure to preserve the value of the eoftoken.
6834 (reader): Make sure eoftoken is defined.
6835 Initialize nsyms to 0: now eoftoken is created just like the others.
6836 * src/print.c (print_grammar): Don't special case the eof token.
6837 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
6838 lie anyway, albeit pleasant.
6839 * tests/calc.at: Exercise error messages with eoftoken.
6840 Change the grammar so that empty input is invalid.
6841 Adjust expectations.
6842 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
6844 2001-12-27 Akim Demaille <akim@epita.fr>
6846 * configure.in: Check the protos of strchr ans strspn.
6847 Replace strchr if needed.
6848 * src/system.h: Provide the protos of strchr, strspn and memchr if
6850 * lib/strchr.c: New.
6851 * src/reader.c (symbols_save): Use strchr.
6853 2001-12-27 Akim Demaille <akim@epita.fr>
6855 * src/print.c, src/print_graph.c (escape): New.
6856 Use it to quote the TAGS outputs.
6857 * src/print_graph.c (print_state): Now errors are in red, and
6858 reductions in green.
6859 Prefer high to wide: output the state number on a line of its own.
6861 2001-12-27 Akim Demaille <akim@epita.fr>
6863 * src/state.h, src/state.c (reductions_new): New.

6868 * src/print.c (print_reductions, print_actions): Adjust.

6884 2001-12-27 Akim Demaille <akim@epita.fr>
6886 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
6887 * src/print.c: here.
6888 (lookaheadset, shiftset): New, used as additional storage by
6890 (print_results): Adjust.
6891 (print_shifts, print_gotos, print_errs): New, extracted from...
6892 (print_actions): here.
6893 * src/print_graph.c (print_actions): Remove dead code.
6895 2001-12-27 Akim Demaille <akim@epita.fr>
6897 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
6900 2001-12-27 Akim Demaille <akim@epita.fr>
6902 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.

6905 2001-12-27 Akim Demaille <akim@epita.fr>
6907 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
6910 2001-12-27 Akim Demaille <akim@epita.fr>
6912 * src/reader.c (packgram): Catch nitems overflows.
6914 2001-12-27 Akim Demaille <akim@epita.fr>
6916 * src/files.c, src/files.h (guard_obstack): Remove.
6917 * src/output.c (output): Adjust.
6918 * src/reader.c (parse_braces): New, factoring...
6919 (copy_action, copy_guard): these two which are renamed as...
6920 (parse_action, parse_guard): these.
6921 As a voluntary consequence, using braces around guards is now
6924 2001-12-27 Akim Demaille <akim@epita.fr>
6926 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
6927 * src/reader.c (symbol_list): `guard' and `guard_line' are new
6929 (symbol_list_new): Adjust.
6930 (copy_action): action_line is the first line, not the last.
6931 (copy_guard): Just as for actions, store the `action' only, not
6932 the switch/case/break flesh.
6933 Don't parse the user action that might follow the guard, let...
6934 (readgram): do it, i.e., now, there can be an action after a
6936 In other words the guard is just explicitly optional.
6938 * src/output.c (guards_output): New.
6939 (output_parser): Call it when needed.
6940 (output): Also free the guard and attrs obstacks.
6941 * src/files.c, src/files.h (obstack_save): Remove.
6942 (output_files): Remove.
6943 As a result, if one needs the former `.act' file, using an
6944 appropriate skeleton which requires actions and guards is now
6946 * src/main.c (main): Adjust.
6947 * tests/semantic.at: New.
6948 * tests/regression.at: Use `input.y' as input file name.
6949 Avoid 8+3 problems by requiring input.c when the test needs the
6952 2001-12-27 Akim Demaille <akim@epita.fr>
6954 * src/reader.c (symbol_list_new): Be sure to initialize all the
6957 2001-12-27 Akim Demaille <akim@epita.fr>
6959 All the hacks using a final pseudo state are now useless.
6961 * src/LR0.c (set_state_table): state_table holds exactly nstates.
6962 * src/lalr.c (nLA): New.
6963 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
6964 instead of lookaheadsp from the pseudo state (nstate + 1).
6966 2001-12-27 Akim Demaille <akim@epita.fr>
6968 * src/output.c (action_row, token_actions): Use a state_t instead
6969 of a integer, and nlookaheads instead of the following state's
6972 2001-12-27 Akim Demaille <akim@epita.fr>
6974 * src/conflicts.c (log_resolution, flush_shift)
6975 (resolve_sr_conflict, set_conflicts, solve_conflicts)
6976 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
6977 (conflicts_print, print_reductions): Use a state_t instead of an
6978 integer when referring to a state.
6979 As much as possible, depend upon nlookaheads, instead of the
6980 `lookaheadsp' member of the following state (since lookaheads of
6981 successive states are successive, the difference between state n + 1
6982 and n served as the number of lookaheads for state n).
6983 * src/lalr.c (add_lookback_edge): Likewise.
6984 * src/print.c (print_core, print_actions, print_state)
6985 (print_results): Likewise.

6992 * src/bison.hairy: Formatting/comment changes.
6994 Remove `register' indications.
6995 Add plenty of `static'.
6997 2001-12-27 Akim Demaille <akim@epita.fr>
6999 * src/output.c (prepare): Drop the muscle `ntbase' which
7001 * src/bison.simple: Formatting/comment changes.
7002 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
7003 is an undocumented synonym.
7005 2001-12-22 Akim Demaille <akim@epita.fr>
7007 * src/output.c (output_table_data): Change the prototype to use
7008 `int' for array ranges: some invocations do pass an int, not a
7010 Reported by Wayne Green.
7012 2001-12-22 Akim Demaille <akim@epita.fr>
7014 Some actions of web2c.y are improperly triggered.
7015 Reported by Mike Castle.
7017 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

7019 (Web2c Report): this.
7020 (Web2c Actions): New.
7022 2001-12-22 Akim Demaille <akim@epita.fr>
7024 Reductions in web2c.y are improperly reported.
7025 Reported by Mike Castle.
7027 * src/conflicts.c (print_reductions): Fix.
7028 * tests/regression.at (Web2c): New.
7030 2001-12-18 Akim Demaille <akim@epita.fr>
7032 Some host fail on `assert (!"foo")', which expands to
7033 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
7034 Reported by Nelson Beebee.
7036 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
7037 `#define it_succeeded 0' and `assert (it_succeeded)'.
7039 2001-12-17 Marc Autret <autret_m@epita.fr>
7041 * src/bison.simple: Don't hard code the skeleton line and filename.
7042 * src/output.c (output_parser): Rename 'line' as 'output_line'.
7043 New line counter 'skeleton_line' (skeleton-line muscle).
7045 2001-12-17 Paul Eggert <eggert@twinsun.com>
7047 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
7048 YYDEBUG must be defined to a nonzero value.
7050 * src/bison.simple (yytname): Do not assume that the user defines
7051 YYDEBUG to a properly parenthesized expression.
7053 2001-12-17 Akim Demaille <akim@epita.fr>
7055 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
7056 nlookaheads is a new member.
7058 * src/lalr.h (nlookaheads): Remove this orphan declaration.
7059 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
7062 2001-12-17 Akim Demaille <akim@epita.fr>
7064 * src/files.h, src/files.c (open_files, close_files): Remove.
7065 * src/main.c (main): Don't open/close files, nor invoke lex_free,
7067 * src/reader.c (reader): Do it.
7069 2001-12-17 Akim Demaille <akim@epita.fr>
7071 * src/conflicts.c (print_reductions): Formatting changes.
7073 2001-12-17 Akim Demaille <akim@epita.fr>
7075 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
7076 (flush_reduce): New.
7077 (resolve_sr_conflict): Adjust.
7079 2001-12-17 Akim Demaille <akim@epita.fr>
7081 * src/output.c (output_obstack): Be static and rename as...
7082 (format_obstack): this, to avoid any confusion with files.c's
7084 * src/reader.h (muscle_obstack): Move to...
7085 * src/output.h: here, since it's defined in output.c.
7087 2001-12-17 Akim Demaille <akim@epita.fr>
7089 * src/output.c (action_row, save_column, default_goto)
7090 (sort_actions, matching_state, pack_vector): Better variable
7093 2001-12-17 Akim Demaille <akim@epita.fr>
7095 * src/output.c: Various formatting changes.
7097 2001-12-17 Akim Demaille <akim@epita.fr>
7099 * src/files.c (output_files): Free the output_obstack.
7100 * src/main.c (main): Call print and print_graph conditionally.
7101 * src/print.c (print): Work unconditionally.
7102 * src/print_graph.c (print_graph): Work unconditionally.
7103 * src/conflicts.c (log_resolution): Output only if verbose_flag.
7105 2001-12-16 Marc Autret <autret_m@epita.fr>
7107 * src/output.c (actions_output): Fix. When we use %no-lines,
7108 there is one less line per action.
7110 2001-12-16 Marc Autret <autret_m@epita.fr>
7112 * src/bison.simple: Remove a useless #line directive.
7113 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
7114 * src/output.c (get_lines_number): New.
7115 (output_parser): Adjust, now takes care about the lines of a
7118 (actions_output): Computes the number of lines taken by actions.
7119 (output_master_parser): Insert new skeleton which is the name of
7120 the output parser file name.
7122 2001-12-15 Marc Autret <autret_m@epita.fr>
7124 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
7126 2001-12-15 Marc Autret <autret_m@epita.fr>
7128 * src/output.c (output_gram): Keep track of the hairy one.
7130 2001-12-15 Akim Demaille <akim@epita.fr>
7132 Make `make distcheck' work.
7134 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
7135 system.h which uses libgettext.h.
7137 2001-12-15 Akim Demaille <akim@epita.fr>
7139 * src/nullable.c (set_nullable): Useless rules must be skipped,
7140 otherwise, since we range over their symbols, we might look at a
7141 nonterminal which no longer ``exists'', i.e., it is not counted in
7142 `nvars', hence we overflow our arrays.
7144 2001-12-15 Akim Demaille <akim@epita.fr>
7146 The header can also be produced directly, without any obstack!
7149 * src/files.c, src/files.h (defines_obstack): Remove.
7150 (compute_header_macro): Global.
7151 (defines_obstack_save): Remove.
7152 * src/reader.c (parse_union_decl): No longer output to
7153 defines_obstack: its content can be found in the `stype' muscle
7155 (output_token_translations): Merge into...
7156 (symbols_output): this.
7158 (symbols_save): this.
7160 * src/output.c (header_output): New.
7163 2001-12-15 Akim Demaille <akim@epita.fr>
7165 * src/reader.c (parse_union_decl): Instead of handling two obstack
7166 simultaneously, use one to define the `stype' muscle, and use the
7167 value of the latter to fill defines_obstack.
7168 (copy_comment): Remove.
7169 (copy_comment2): Work for a single obstack.
7171 (copy_comment): this.
7173 2001-12-15 Akim Demaille <akim@epita.fr>
7175 * src/lex.c, src/lex.h (xgetc): No longer static.
7176 * src/reader.c (parse_union_decl): Revamp.
7178 2001-12-15 Akim Demaille <akim@epita.fr>
7180 Still making progress in separating Bison into (i) input, (ii)
7181 process, (iii) output: now we can directly output the parser file
7182 without using table_obstack at all.
7184 * src/files.c, src/files.h (table_obstack): Bye bye.
7185 (parser_file_name): New.
7186 * src/files.c (compute_output_file_names): Compute it.
7187 * src/output.c (actions_output, output_parser)
7188 (output_master_parser): To a file instead of an obstack.
7190 2001-12-15 Akim Demaille <akim@epita.fr>
7192 Attach actions to rules, instead of pre-outputting them to
7195 * src/gram.h (rule_t): action and action_line are new members.
7196 * src/reader.c (symbol_list): Likewise.
7197 (copy_action): Save the actions within the rule.
7198 (packgram): Save them in rule_table.
7199 * src/output.c (actions_output): New.
7200 (output_parser): Use it on `%%actions'.
7201 (output_rule_data): Don't free rule_table.
7203 (prepare): Don't save the `action' muscle.
7204 * src/bison.simple: s/%%action/%%actions/.
7206 2001-12-15 Akim Demaille <akim@epita.fr>
7208 * src/reader.c (copy_action): When --yacc, don't append a `;'
7209 to the user action: let it fail if lacking.
7210 Suggested by Arnold Robbins and Tom Tromey.
7212 2001-12-14 Akim Demaille <akim@epita.fr>
7214 * src/lex.c (literalchar): Simply return the char you decoded, non
7215 longer mess around with obstacks and int pointers.
7218 2001-12-14 Akim Demaille <akim@epita.fr>
7220 * src/lex.c (literalchar): Don't escape the special characters,
7221 just decode them, and keep them as char (before, eol was output as
7222 the 2 char string `\n' etc.).
7223 * src/output.c (output_rule_data): Use quotearg to output the
7226 2001-12-13 Paul Eggert <eggert@twinsun.com>
7228 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
7229 Do not infringe on the global user namespace when using C++.
7230 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
7231 All uses of `fprintf' and `stderr' changed.
7233 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
7235 2001-12-13 Akim Demaille <akim@epita.fr>
7237 The computation of nullable is broken: it doesn't handle empty
7240 * tests/torture.at (GNU AWK Grammar): New.
7241 * tests/sets.at (Nullable): New.
7242 * src/nullable.c (set_nullable): Instead of blindly looping over
7243 `ritems', loop over the rules, and then over their rhs's.
7245 Work around Autotest bugs.
7247 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
7248 frame, because Autotest understand lines starting with a `+' as
7249 traces from the shell. Then, they are not processed properly.
7250 Admittedly an Autotest bug, but we don't have time to wait for
7251 Autotest to catch up.
7252 * tests/regression.at (Broken Closure): Adjust to the new table
7255 * tests/sets.at: here.
7257 2001-12-13 Akim Demaille <akim@epita.fr>
7259 * src/closure.c (closure): Use nrules instead of playing tricks
7262 2001-12-13 Akim Demaille <akim@epita.fr>
7264 * src/print.c (print_actions): Output the handling of `$' as the
7265 traces do: shifting the token EOF. Before EOF was treated as a
7267 * tests/regression.at: Adjust some tests.
7268 * src/print_graph.c (print_core): Complete the set of items via
7269 closure. The next-to-final and final states are still unsatisfying,
7270 but that's to be addressed elsewhere.
7271 No longer output the rule numbers, but do output the state number.
7272 A single loop for the shifts + gotos is enough, but picked a
7273 distinct color for each.
7274 (print_graph): Initialize and finalize closure.
7276 2001-12-13 Akim Demaille <akim@epita.fr>
7278 * src/reader.c (readgram): Remove dead code, an strip useless
7280 (get_type): Remove, unused.
7282 2001-12-12 Akim Demaille <akim@epita.fr>
7284 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
7285 on that of lib/error.c.
7287 2001-12-12 Akim Demaille <akim@epita.fr>
7289 Some hosts don't like `/' in includes.
7291 * src/system.h: Include libgettext.h without qualifying the path.
7292 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
7295 2001-12-11 Marc Autret <autret_m@epita.fr>
7297 * src/output.c (output_parser): Remove useless muscle.
7299 2001-12-11 Marc Autret <autret_m@epita.fr>
7301 * src/bison.simple: Remove #line just before %%epilogue. It
7302 is now handled in ...
7303 * src/reader.c (read_additionnal_code): Add the output of a
7304 #line for the epilogue.
7306 2001-12-10 Marc Autret <autret_m@epita.fr>
7308 * src/reader.c (copy_definition): Re-use CPP-outed code which
7309 replace precedent remove.
7310 * src/bison.simple: Remove #line before %%prologue because
7311 %%input-line is wrong at this time.
7313 2001-12-10 Marc Autret <autret_m@epita.fr>
7315 * src/reader.c (symbols_output): Clean up.
7316 * src/output.c (output_gram, output): Clean up.
7318 2001-12-10 Akim Demaille <akim@epita.fr>
7320 * src/lalr.c (initialize_lookaheads): New. Extracted from...
7321 * src/LR0.c (set_state_table): here.
7322 * src/lalr.c (lalr): Call it.
7324 2001-12-10 Akim Demaille <akim@epita.fr>
7326 * src/state.h (shifts): Remove the `number' member: shifts are
7327 attached to state, hence no longer need to be labelled with a
7330 2001-12-10 Akim Demaille <akim@epita.fr>
7332 Now that states have a complete set of members, the linked list of
7333 shifts is useless: just fill directly the state's shifts member.
7335 * src/state.h (shifts): Remove the `next' member.
7336 * src/LR0.c (first_state, last_state): Remove.
7338 (augment_automaton): Don't look for the shifts that must be added
7339 a shift on EOF: it is those of the state we looked for! But now,
7340 since shifts are attached, it is no longer needed to looking
7341 merely by its id: its number.
7343 2001-12-10 Akim Demaille <akim@epita.fr>
7345 * src/LR0.c (augment_automaton): Better variable locality.
7346 Remove an impossible branch: if there is a state corresponding to
7347 the start symbol being shifted, then there is shift for the start
7348 symbol from the initial state.
7350 2001-12-10 Akim Demaille <akim@epita.fr>
7352 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
7353 only when appropriate: when insert_start_shifting_state' is not
7355 * tests/regression.at (Rule Line Numbers): Adjust.
7357 2001-12-10 Akim Demaille <akim@epita.fr>
7359 * src/LR0.c (augment_automaton): Now that all states have shifts,
7360 merge the two cases addition shifts to the initial state.
7362 2001-12-10 Akim Demaille <akim@epita.fr>
7364 * src/lalr.c (set_state_table): Move to...
7366 * src/lalr.c (lalr): Don't call it...
7367 * src/LR0.c (generate_states): do it.
7368 * src/LR0.h (first_state): Remove, only the table is used.
7370 2001-12-10 Akim Demaille <akim@epita.fr>
7372 * src/LR0.h (first_shift, first_reduction): Remove.
7373 * src/lalr.c: Don't use first_shift: find shifts through the
7376 2001-12-10 Akim Demaille <akim@epita.fr>
7378 * src/LR0.c: Attach shifts to states as soon as they are
7380 * src/lalr.c (set_state_table): Instead of assigning shifts to
7381 state, just assert that the mapping was properly done.
7383 2001-12-10 Akim Demaille <akim@epita.fr>
7385 * src/LR0.c (insert_start_shift): Rename as...
7386 (insert_start_shifting_state): this.
7387 (insert_eof_shifting_state, insert_accepting_state): New.
7388 (augment_automaton): Adjust.
7389 Better locality of the variables.
7390 When looking if the start_symbol is shifted from the initial
7391 state, using `while (... symbol != start_symbol ...)' sounds
7392 better than `while (... symbol < start_symbol ...)': If fail
7393 to see how the order between symbols could be relevant!
7395 2001-12-10 Akim Demaille <akim@epita.fr>
7397 * src/getargs.h: Don't declare `spec_name_prefix' and
7398 `spec_file_prefix', declared by src/files.h.
7399 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
7400 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
7401 * src/output.c (prepare): Adjust.
7402 * src/reader.c (symbols_output): Likewise.

7405 2001-12-10 Akim Demaille <akim@epita.fr>
7407 * src/muscle_tab.c (muscle_init): NULL is a better default than
7410 2001-12-10 Akim Demaille <akim@epita.fr>
7412 * src/reader.c (reader): Calling symbols_output once is enough.
7414 2001-12-10 Akim Demaille <akim@epita.fr>
7416 Now that states have a complete set of members, the linked list of
7417 reductions is useless: just fill directly the state's reductions
7420 * src/state.h (struct reductions): Remove member `number' and
7422 * src/LR0.c (first_reduction, last_reduction): Remove.
7423 (save_reductions): Don't link the new reductions, store them in
7425 * src/lalr.c (set_state_table): No need to attach reductions to
7426 states, it's already done.
7427 * src/output.c (output_actions): No longer free the shifts, then
7428 the reductions, then the states: free all the states and their
7431 2001-12-10 Akim Demaille <akim@epita.fr>
7433 * src/options.c (OPTN, DRTV, BOTH): New.
7434 (option_table): Use them.
7436 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
7437 the job of system.h.
7438 * src/options.c: Don't include stdio.h and xalloc.h for the same
7441 2001-12-10 Akim Demaille <akim@epita.fr>
7443 * src/output.c (output, prepare): Make sure the values of the
7444 muscles `action' and `prologue' are 0-terminated.
7446 2001-12-10 Akim Demaille <akim@epita.fr>
7448 Clean up GCC warnings.
7450 * src/reader.c (copy_action): `buf' is not used.
7451 (parse_skel_decl): Be static.
7452 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
7453 * src/options.h (create_long_option_table): Have a real prototype.
7454 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
7455 (hash_delete_at): Return const void *.
7456 Adjust casts to preserve the const.
7458 2001-12-10 Akim Demaille <akim@epita.fr>
7460 * configure.in: Require 2.52g.
7461 M4 is not needed, but AUTOM4TE is.
7463 * tests/Makefile.am: Adjust.
7465 2001-12-10 Akim Demaille <akim@epita.fr>
7467 One structure for states is enough, even though theoretically
7468 there are LR(0) states and LALR(1) states.
7470 * src/lalr.h (state_t): Remove.
7471 (state_table): Be state_t **, not state_t *.
7472 * src/state.h (core, CORE_ALLOC): Rename as...
7473 (state_t, STATE_ALLOC): this.
7474 Add the LALR(1) members: shifts, reductions, errs.
7475 * src/LR0.c (state_table): Rename as...
7476 (state_hash): this, to avoid name clashes with the global
7478 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
7479 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
7481 2001-12-10 Akim Demaille <akim@epita.fr>
7483 Bison dumps core on bash.y.
7484 Reported by Pascal Bart.
7486 * src/warshall.c (bitmatrix_print): New.
7488 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
7489 j must be the outer loop.
7490 * tests/regression.at (Broken Closure): New.
7492 2001-12-05 Akim Demaille <akim@epita.fr>
7494 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
7496 Reported by Peter Hamorsky.

7500 * src/conflicts.c (err_table): Remove.
7501 (resolve_sr_conflict): Adjust.
7502 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
7504 (state_t.reductions, state_t.shifts): this.
7506 2001-12-05 Akim Demaille <akim@epita.fr>
7508 * src/reduce.c (reduce_grammar_tables): No longer disable the
7509 removal of useless rules via CPP but via `if (0)', so that the
7510 compiler still check the code is valid.
7511 For instance, it should have noticed `rline' no longer exists: use
7512 the `line' member of rule_t.
7513 * src/gram.c (dummy, rline): Remove, unused.
7515 2001-12-05 Akim Demaille <akim@epita.fr>
7517 * src/output.c (pack_vector): Use assert, not berror.
7518 * src/main.c (berror): Remove, unused.
7520 2001-12-05 Akim Demaille <akim@epita.fr>
7522 New experimental feature: if --verbose --trace output all the
7523 items of a state, not only its kernel.
7525 * src/print.c (print_core): If `trace_flag', then invoke closure
7526 before outputting the items of the state (print_core is no longer
7527 a correct name them).
7528 (print_results): Invoke new_closure/free_closure if needed.
7530 2001-12-05 Akim Demaille <akim@epita.fr>
7532 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
7533 * src/closure.c, src/closure.h (itemsetsize): Rename as...
7534 (nitemset): for consistency with the rest of the project.
7536 2001-12-05 Akim Demaille <akim@epita.fr>
7538 * src/closure.c (print_closure): Improve.
7539 (closure): Use it for printing input and output.
7541 2001-12-05 Akim Demaille <akim@epita.fr>
7543 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
7544 indexed by nonterminals.
7546 2001-12-05 Akim Demaille <akim@epita.fr>
7548 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

7566 * src/output.c (action_row): De-obfuscate
7567 using the good o' techniques: arrays not pointers, variable
7568 locality, BITISSET, RESETBIT etc.
7570 2001-12-05 Akim Demaille <akim@epita.fr>
7572 Pessimize the code to simplify it: from now on, all the states
7573 have a valid SHIFTS, which NSHIFTS is possibly 0.
7575 * src/LR0.c (shifts_new): Be global and move to..
7576 * src/state.c, src/state.h: here.
7577 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
7578 * src/print_graph: Adjust.
7580 2001-12-05 Akim Demaille <akim@epita.fr>
7582 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
7583 * src/conflicts.c: Use it.
7584 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
7585 incorrectly ``simplified''.
7587 2001-12-05 Akim Demaille <akim@epita.fr>
7589 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
7590 using the good o' techniques: arrays not pointers, variable

7595 * src/state.h (SHIFT_SYMBOL): New.
7596 * src/conflicts.c: Use it to deobfuscate.

7600 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
7601 (print_reductions): De-obfuscate using the good o' techniques:
7602 arrays not pointers, variable locality, BITISSET.
7604 2001-12-05 Akim Demaille <akim@epita.fr>
7606 * src/conflicts.c (print_reductions): Arrays, not pointers.

7638 (transpose): Use it.
7639 Use arrays instead of pointers.
7641 2001-12-05 Akim Demaille <akim@epita.fr>
7643 * src/lalr.c (maxrhs): Move to...
7644 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
7645 * src/lalr.c (build_relations): Adjust.
7647 2001-12-05 Akim Demaille <akim@epita.fr>
7649 * src/lalr.c (transpose): Free the memory allocated to the
7650 argument, as it is replaced by the results by the unique caller.
7651 (build_relations): Merely invoke transpose: it handles the memory
7653 Improve variable locality.
7654 Avoid variables used as mere abbreviations.
7655 (compute_lookaheads): Use arrays instead of pointers.
7657 2001-12-05 Akim Demaille <akim@epita.fr>
7659 * src/lalr.c (initialize_F): Improve variable locality.

7664 * src/derives.c (print_derives): Display the ruleno.
7665 * src/lalr.c (initialize_F, transpose): Better variable locality
7666 to improve readability.
7667 Avoid variables used as mere abbreviations.
7669 2001-12-05 Akim Demaille <akim@epita.fr>
7671 * src/lalr.c (traverse): Use arrays instead of pointers.
7673 2001-12-05 Akim Demaille <akim@epita.fr>
7675 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
7676 the handling of squeue.
7677 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
7679 2001-12-05 Akim Demaille <akim@epita.fr>
7681 Because useless nonterminals are now kept alive (instead of being
7682 `destroyed'), we now sometimes examine them, and store information
7683 related to them. Hence we need to know their number, and adjust
7686 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
7688 * src/LR0.c (allocate_itemsets): The memory allocated to
7689 `symbol_count' was used for two different purpose: once to count
7690 the number of occurrences of each symbol, and later reassigned to
7691 `shift_symbol', containing the symbol that can be shifted from a
7693 Deobfuscate, i.e., allocate, use and free `symbol_count' here
7695 (new_itemsets): Allocate `shift_symbol' here.
7696 (allocate_itemsets): symbol_count includes useless nonterminals.
7698 (free_storage): Use `free', not `XFREE', for pointers that cannot
7701 2001-12-05 Akim Demaille <akim@epita.fr>
7703 * src/nullable.c (set_nullable): Deobfuscate the handling of
7705 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
7707 2001-12-05 Akim Demaille <akim@epita.fr>
7709 * src/gram.c, src/gram.h (ritem_print): New.
7710 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
7711 (This useless function was defined only to work around VMS linkers
7712 that can't handle compilation units with variables only).
7713 * src/reduce.c (dump_grammar): Use it to trace the construction of
7716 2001-12-04 Paul Eggert <eggert@twinsun.com>
7718 * src/bison.simple (union yyalloc): Change member names
7719 to be the same as the stack names.
7720 (yyparse): yyptr is now union yyalloc *, not char *.
7721 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
7722 and may generate better code on some machines.
7723 (yystpcpy): Use prototype if __STDC__ is defined, not just
7724 if __cplusplus is defined.
7726 2001-11-30 Akim Demaille <akim@epita.fr>
7728 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
7729 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
7730 Gettext doesn't compile cleanly, and dies with -Werror.
7731 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
7732 Include WARNING_CFLAGS here.
7733 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
7734 before being defined.

7738 * lib/quotearg.h (quotearg_n, quotearg_n_style):
7739 First arg is int, not unsigned.
7740 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
7741 (SIZE_MAX, UINT_MAX): New macros.
7742 (quotearg_n_options): Abort if N is negative.
7743 Avoid overflow check on hosts where size_t is 64 bits and int
7744 is 32 bits, as overflow is impossible there.
7745 Fix off-by-one typo that caused unnecessary reallocation.
7747 2001-11-29 Paul Eggert <eggert@twinsun.com>
7749 Name space cleanup in generated parser.
7751 * doc/bison.texinfo (Bison Parser): Discuss system headers
7752 and their effect on the user name space.
7755 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
7756 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
7757 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
7759 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
7760 on user names when possible.
7762 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
7763 Simplify test for whather <alloca.h> exists.
7765 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
7767 (<stdio.h>): Include if YYDEBUG.
7769 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
7770 ! defined (yyoverflow) && ! defined (yymemcpy).
7772 (yymemcpy, yyparse): Rename local variables as needed so that
7773 they all begin with 'yy'.
7775 (yystrlen, yystpcpy): New functions.
7777 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
7780 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
7781 instead of relying on string.h functions. Use YYSTACK_ALLOC
7782 and YYSTACK_FREE instead of malloc and free.
7784 2001-11-30 Akim Demaille <akim@epita.fr>
7786 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
7787 before their first uses.
7788 (YYBISON, YYPURE): Move to the top of the output.
7790 2001-11-30 Akim Demaille <akim@epita.fr>
7792 * tests/reduce.at (Useless Nonterminals): Fix.
7794 2001-11-30 Akim Demaille <akim@epita.fr>
7796 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
7797 if body instead of `;' to pacify GCC's warnings.
7799 2001-11-30 Akim Demaille <akim@epita.fr>
7801 Instead of mapping the LHS of unused rules to -1, keep the LHS
7802 valid, but flag the rules as invalid.
7804 * src/gram.h (rule_t): `useful' is a new member.
7805 * src/print.c (print_grammar): Adjust.
7806 * src/derives.c (set_derives): Likewise.
7807 * src/reader.c (packgram, reduce_output): Likewise.
7808 * src/reduce.c (reduce_grammar_tables): Likewise.
7809 * tests/reduce.at (Underivable Rules, Useless Rules): New.
7811 2001-11-30 Akim Demaille <akim@epita.fr>
7813 * src/reduce.c (reduce_output): Formatting changes.
7814 * src/print.c (print_results, print_grammar): Likewise.
7815 * tests/regression.at (Rule Line Numbers)
7816 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
7818 2001-11-30 Akim Demaille <akim@epita.fr>
7820 * src/reduce.c (nonterminals_reduce): Instead of throwing away
7821 useless nonterminals, move them at the end of the symbol arrays.
7822 (reduce_output): Adjust.
7823 * tests/reduce.at (Useless Nonterminals): Adjust.
7825 2001-11-30 Akim Demaille <akim@epita.fr>
7827 * src/reduce.c: Various comment/formatting changes.
7828 (nonterminals_reduce): New, extracted from...
7829 (reduce_grammar_tables): here.
7830 (reduce_grammar): Call nonterminals_reduce.
7832 2001-11-29 Paul Eggert <eggert@twinsun.com>
7834 * src/bison.simple (YYSTACK_REALLOC): Remove.
7835 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
7836 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
7838 (union yyalloc): New type.
7839 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
7840 an arbitrary restriction on hosts where size_t is wider than int.
7842 (yyparse): Don't dump core if alloca or malloc fails; instead, report
7843 a parser stack overflow. Allocate just one block of memory for all
7844 three stacks, instead of allocating three blocks; this typically is
7845 faster and reduces fragmentation.
7847 Do not limit the number of items in the stack to a value that fits
7848 in 'int', as this is an arbitrary limit on hosts with 64-bit
7849 size_t and 32-bit int.
7851 2001-11-29 Marc Autret <autret_m@epita.fr>
7853 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
7854 of defining YYERROR_VERBOSE.
7855 [AT_DATA]: $4 is now out of C declarations in the prologue.
7857 2001-11-28 Marc Autret <autret_m@epita.fr>

7864 2001-11-28 Marc Autret <autret_m@epita.fr>
7866 * src/output.h: And put its extern declaration here.
7867 * src/output.c (error_verbose): Define here.
7868 (prepare): Echo name modification.
7869 * src/getargs.h: Clean its extern declaration.
7870 * src/getargs.c (error_verbose_flag): Remove.
7871 (getargs): Remove case 'e'.
7872 * src/options.c (option_table): 'error-verbose' is now seen as simple
7876 * src/reader.c (read_declarations): Remove case tok_include.
7877 (parse_include_decl): Remove.
7878 * src/lex.h (token_t): Remove tok_include.

7885 * src/muscle_tab.c (muscle_init): Also rename the muscles.
7886 * src/output.c (prepare): s/_/-/ for the muscles names.

10071 * src/derives.c, src/print.c, src/reduce.c: To ease the
10072 translation, move some `\n' out of the translated strings.
10074 2000-10-02 Akim Demaille <akim@epita.fr>
10076 The location tracking mechanism is precious for parse error
10077 messages. Nevertheless, it is enabled only when `@n' is used in
10078 the grammar, which is a different issue (you can use it in error
10079 message, but not in the grammar per se). Therefore, there should
10080 be another means to enable it.
10082 * src/getargs.c (getargs): Support `--locations'.
10083 (usage): Report it.
10084 * src/getargs.h (locationsflag): Export it.
10085 * src/lex.c (percent_table): Support `%locations'.
10086 * src/reader.c (yylsp_needed): Remove this variable, now replaced
10087 with `locationsflag'.
10088 * doc/bison.texinfo: Document `--locations' and `%locations'.
10090 * tests/calc.m4: Test it.
10092 For regularity of the names, replace each
10093 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
10094 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
10095 In addition replace each `flag' with `_flag'.
10097 2000-10-02 Akim Demaille <akim@epita.fr>
10099 Also test parse error messages, including with YYERROR_VERBOSE.
10101 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
10103 Use it to check the computations.
10104 Use it to check `nonassoc' is honored.
10105 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
10106 `--yyerror-verbose'.
10107 (_AT_CHECK_CALC): Adjust to this option.
10108 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
10110 2000-10-02 Akim Demaille <akim@epita.fr>
10112 Test also `--verbose', `--defines' and `--name-prefix'. Testing
10113 the latter demonstrates a flaw in the handling of non debugging
10114 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
10115 was used in order to simplify:
10131 unfortunately this leads to a CPP conflict when
10132 `--name-prefix=foo' is used since it produces `#define yydebug
10135 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
10136 (YYDPRINTF): New macro.
10138 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
10140 Also test `--verbose', `--defines' and `--name-prefix'.
10142 2000-10-02 Akim Demaille <akim@epita.fr>
10144 Improve the readability of the produced parsers.
10146 * src/bison.s1: Formatting changes.
10147 Improve the comment related to the `$' mark.
10148 (yydefault): Don't fall through to `yyresume': `goto' there.
10149 * src/output.c (output_parser): When the `$' is met, skip the end
10151 New variable, `number_of_dollar_signs', to check there's exactly
10152 one `$' in the parser skeleton.
10154 2000-10-02 Akim Demaille <akim@epita.fr>
10156 * lib/xstrdup.c: New file, from the fileutils.
10157 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
10158 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
10159 instead of strlen + xmalloc + strcpy.
10160 * src/symtab.c (copys): Remove, use xstrdup instead.
10162 2000-10-02 Akim Demaille <akim@epita.fr>
10164 * src/gram.h (associativity): New enum type which replaces the
10165 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
10166 `right_assoc', `left_assoc' and `non_assoc'.
10167 Adjust all dependencies.
10168 * src/reader.c: Formatting changes.
10169 (LTYPESTR): Don't define it, use it as a literal in
10170 `reader_output_yylsp'.
10171 * src/symtab.h (symbol_class): New enum type which replaces the
10172 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
10173 `sunknown', `stoken and `snterm'.
10175 2000-10-02 Akim Demaille <akim@epita.fr>
10177 * src/getargs.c (fixed_outfiles): Rename as...
10178 (yaccflag): for consistency and accuracy.
10179 Adjust dependencies.
10181 2000-10-02 Akim Demaille <akim@epita.fr>
10183 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
10184 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
10185 difficult and introduced a lot of core dump. It turns out that
10186 Bison used an implementation of `xmalloc' based on `calloc', and
10187 at various places it does depend upon the initialization to 0. I
10188 have not tried to isolate the pertinent places, and all the former
10189 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
10190 someone should address this issue.
10192 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
10193 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

10199 2000-10-02 Akim Demaille <akim@epita.fr>
10201 Various anti-`extern in *.c' changes.
10203 * src/system.h: Include `assert.h'.
10205 2000-10-02 Akim Demaille <akim@epita.fr>
10207 * src/state.h (nstates, final_state, first_state, first_shift)
10208 (first_reduction): Move their exportation from here...
10209 * src/LR0.h: to here.
10210 Adjust dependencies.
10211 * src/getargs.c (statisticsflag): New variable.
10212 Add support for `--statistics'.
10213 Adjust dependencies.
10215 Remove a lot of now useless `extern' statements in most files.

10219 * src/LR0.h: New file.
10222 2000-10-02 Akim Demaille <akim@epita.fr>

10249 Propagate its inclusion.
10250 * src/reduce.c: Topological sort and other formatting changes.
10251 (bool, TRUE, FALSE): Move their definition to...
10252 * src/system.h: here.
10254 2000-10-02 Akim Demaille <akim@epita.fr>
10256 * src/files.c: Formatting changes.
10257 (tryopen, tryclose, openfiles): Rename as...
10258 (xfopen, xfclose, open_files): this.
10259 (stringappend): static.

10283 * src/lalr.c: Formatting changes, topological sorting etc.
10285 2000-10-02 Akim Demaille <akim@epita.fr>
10287 * src/output.c (token_actions): Introduce a temporary array,
10288 YYDEFACT, that makes it possible for this function to use
10289 output_short_table.
10291 2000-10-02 Akim Demaille <akim@epita.fr>
10293 `user_toknums' is output as a `short[]' in `output.c', while it is
10294 defined as a `int[]' in `reader.c'. For consistency with the
10295 other output tables, `user_toknums' is now defined as a table of

10311 order to get rid of the `static' prototypes.
10312 No longer use `register'.

10338 Don't define PARAMS.
10339 * src/system.h: Define PARAMS.
10340 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
10341 purpose of config.h. system.h must not try to fix wrong
10342 definitions in config.h.

10468 complain.c::complain.
10469 (toomany): Remove, use fatal instead.

10471 * src/main.c (main): Register `done' to `atexit'.

10539 (copy_comment): Likewise.
10541 2000-03-17 Akim Demaille <akim@epita.fr>

10556 (copy_guard): Likewise.
10558 2000-03-17 Akim Demaille <akim@epita.fr>
10560 Change the handling of @s so that they behave exactly like $s.
10561 There is now a pseudo variable @$ (readble and writable), location
10562 of the lhs of the rule (by default ranging from the location of
10563 the first symbol of the rhs, to the location of the last symbol,
10564 or, if the rhs is empty, YYLLOC).
10566 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
10568 (yyparse): When providing a default semantic action, provide a
10569 default location action.
10570 (after the $): No longer change `*YYLSP', just stack YYLOC the
10571 same way you stack YYVAL.
10572 * src/reader.c (read_declarations): Use warns.
10573 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
10574 (copy_action, case '@'): Likewise.
10575 Use a standard error message, to save useless work from

10596 2000-03-16 Akim Demaille <akim@epita.fr>
10598 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
10599 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
10600 One `#if YYDEBUG' remains, since it uses variables which are
10601 defined only if `YYDEBUG != 0'.
10603 2000-03-16 Akim Demaille <akim@epita.fr>
10605 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

11258 1995-10-15 Richard Stallman <rms@gnu.org>
11260 * src/vmsgetargs.c, src/getargs.c:

11270 (print_notices): Remove final `.' from error message.
11272 * src/reader.c (reader_output_yylsp):
11274 (readgram): Use `#if 0' around code that accepted %command
11275 inside grammar rules: The documentation doesn't allow it,
11276 and it will fail since the %command processors scan for the next %.
11277 (parse_token_decl): Extended the %token
11278 declaration to allow a multi-character symbol as an alias.
11279 (parse_thong_decl): New function.
11280 (read_declarations): Added %thong declarations.
11281 (read_declarations): Handle NOOP to deal with allowing
11282 % declarations as another means to specify the flags.
11283 (readgram): Allow %prec prior to semantics embedded in a rule.
11284 (skip_to_char, read_declarations, copy_definition)
11285 (parse_token_decl, parse_start_decl, parse_type_decl)
11286 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
11287 (get_type_name, copy_guard, copy_action, readgram)
11288 (get_type, packsymbols): Revised most error messages.
11289 Changed `fatal' to `warnxxx' to avoid aborting for error.
11290 Revised and use multiple warnxxx functions to avoid using VARARGS1.
11291 (read_declarations): Improve the error message for
11292 an invalid character. Do not abort.
11293 (read_declarations, copy_guard, copy_action): Use
11294 printable_version to avoid unprintable characters in printed output.
11295 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
11296 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
11297 Allow the type of a non-terminal can be given
11298 more than once, as long as all specifications give the same type.
11301 (output_headers, output_trailers, output, output_gram)
11302 (output_rule_data): Implement noparserflag variable.
11303 Implement toknumflag variable.
11304 (output): Call reader_output_yylsp to output LTYPESTR.
11306 * src/main.c (main):
11307 If reader sees an error, don't process the grammar.
11308 (fatals): Updated to not use VARARGS1.
11309 (printable_version, int_to_string, warn, warni, warns, warnss)
11310 (warnsss): New error reporting functions. Avoid abort for error.
11313 Added THONG and NOOP for alias processing.
11314 Added SETOPT for the new code that allows setting options with %flags.
11317 Include getopt.h. Add some extern decls.
11318 (safegetc): New function to deal with EOF gracefully.
11319 (literalchar); new function to deal with reading \ escapes.
11320 (lex): Use literalchar.
11321 (lex): Implemented "..." tokens.
11322 (literalchar, lex, parse_percent_token): Made tokenbuffer
11323 always contain the token. This includes growing the token
11324 buffer while reading an integer.
11325 (parse_percent_token): Replaced if-else statement with percent_table.
11326 (parse_percent_token): Added % declarations as another
11327 way to specify the flags -n, -l, and -r. Also added hooks for
11328 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
11329 major changes to files.c.
11330 (lex) Retain in the incoming stream a character following
11332 (skip_white_space, lex): Revised most error messages
11333 and changed fatal to warn to avoid aborting.
11334 (percent_table): Added %thong declarations.
11336 * src/gram.h: Comment changes.
11338 * src/files.c (openfiles, open_extra_files, done):
11340 and actfile file. Handle noparserflag. Both for -n switch.
11342 * src/conflicts.c (resolve_sr_conflict):
11343 Remove use of alloca.
