+
+ Tune local.at so that people can "autom4te -l autotest calc.at -o
+ calc" for instance, to extract a sub test suite.
+
+ * tests/testsuite.at: Move the initialization, Autotest version
+ requirement, and AT_TESTED invocation into...
+ * tests/local.at: here.
+ * tests/testsuite.at: Include it for compatibility with Autoconf
+ 2.57.
+ * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
+ be ignore.
+
+2003-08-04 Paul Eggert <eggert@twinsun.com>
+
+ Rework code slightly to avoid gcc -Wtraditional warnings.
+ * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
+ The returned value is now stored in *YY0. All callers changed.
+ * src/output.c (merge_output): Adjust to the above change.
+
+2003-07-26 Paul Eggert <eggert@twinsun.com>
+
+ * data/glr.c (YYASSERT): New macro.
+ (yyfillin, yydoAction, yyglrReduce, yysplitStack,
+ yyresolveStates, yyprocessOneStack):
+ Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
+ Derived from a suggestion by Frank Heckenbach.
+
+2003-07-25 Paul Eggert <eggert@twinsun.com>
+
+ * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
+ for portability to K&R C (after ansi2knr, presumably). See
+ <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
+ by Frank Heckenbach, though I have omitted the structure-initialization
+ part of his glr-knr.diff patch since I recall that the Portable
+ C Compiler didn't require that change.
+
+ Let the user specify how to allocate and free memory.
+ Derived from a suggestion by Frank Heckenbach in
+ <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
+ * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
+ All uses of free, malloc, realloc changed to use these macros,
+ and unnecessary casts removed.
+ * data/yacc.c (YYFREE, YYMALLOC): Likewise.
+
+2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
+
+ * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
+ use s.empty() rather than s == "" to test for empty string; see
+ <http://mail.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
+ (trivial change)
+
+2003-06-25 Akim Demaille <akim@epita.fr>
+
+ * config/depcomp, config/install-sh: Update from masters.
+
+2003-06-20 Paul Eggert <eggert@twinsun.com>
+
+ * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
+ and return properly parenthesized result.
+ * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
+ * data/yacc.c (YYLLOC_DEFAULT): Likewise.
+ Remove unnecessary parentheses from uses.
+ * doc/bison.texinfo (Location Default Action): Describe the
+ conventions for parentheses.
+
+2003-06-19 Paul Eggert <eggert@twinsun.com>
+
+ * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
+ yyreportTree): Do not assume that size_t is the same width as int,
+ when printing sizes. Print sizes using an unsigned format.
+ Problem reported by Frank Heckenbach in
+ <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
+
+ Port to Forte Developer 7 C compiler.
+ * data/glr.c (struct YYLTYPE): If locations are not being used,
+ declare a single dummy member, as empty structs do not conform
+ to the C standard.
+ (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
+ the Forte Developer 7 C compiler complains that end-of-loop
+ code is not reached.
+
+2003-06-17 Paul Eggert <eggert@twinsun.com>
+
+ * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
+ avoid warnings from picky compilers about redefinition of PARAMS.
+
+2003-06-17 Paul Eggert <eggert@twinsun.com>
+
+ Version 1.875b.
+
+ * NEWS: Document 1.875b.
+
+ * lib/bbitset.h: Do not include config.h; that's the includer's job.
+ Do not include <sys/types.h>; shouldn't be needed on a C89 host.
+ * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
+ Don't use 'index' in comments, as it's a builtin fn on some hosts.
+ * lib/bitset_stats.c: Include gettext.h unconditionally, as
+ per recent gettext manual's suggestion.
+ * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):

+
+ Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
+ <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
+ * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.

+ lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
+ from libbitset.
+
+ * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
+ `How Can I Reset @code{yyparse}', since texinfo does not allow
+ arbitrary @ in node names.
+
+ * m4/Makefile.am (EXTRA_DIST): Add the following files, which
+ shouldn't be needed according to the gettext 0.12.1 documentation
+ but which seem to be needed anyway: codeset.m4 glibc21.m4
+ intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
+ lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
+ * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
+
+ * lib/.cvsignore: Add stdbool.h.
+ * m4/.cvsignore: Add nls.m4, po.m4.
+
+ Upgrade to CVS gnulib.
+ * stdbool_.h: File renamed from stdbool.h.in.
+ * configure.ac (AM_STDBOOL_H): Invoke this instead of
+ AC_HEADER_STDBOOL.
+ (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
+ (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
+ * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
+ (MOSTLYCLEANFILES): New var.
+ ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
+ (stdbool.h): New rule.

+ lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
+ m4/quote.m4: Upgrade to today's gnulib.
+
+ * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
+ (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
+ the tests right now.
+ * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
+ yyerror are declared before use; C99 requires this.
+
+2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
+
+ * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
+ first.
+ (yyrecoverSyntaxError): Correct the logic for setting and testing
+ yyerrState.
+ Correct comment on handling EOF.
+ Allow states with only a default reduction, rather than failing
+ (I can't quite reconstruct why these were not allowed before).
+
+ Fixes to avoid problem that $-N rules in GLR parsers can cause
+ buffer overruns, corrupting state.
+
+ * src/output.c (prepare_rules): Output max_left_semantic_context
+ definition.
+ * src/reader.h (max_left_semantic_context): New variable declaration.
+ * src/scan-gram.l (max_left_semantic_context): Define.
+ (handle_action_dollar): Update max_left_semantic_context.
+ * data/glr.c (YYMAXLEFT): New definition.
+ (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
+ (yyresolveAction): Ditto.
+
+ Fixes to problems with location handling in GLR parsers reported by
+ Frank Heckenbach (2003/06/05).
+
+ * data/glr.c (YYLTYPE): Make trivial if locations not used.
+ (YYRHSLOC): Add parentheses, and define only if locations used.
+ (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
+ locations not used.
+ (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
+ (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
+
+ * tests/cxx-type.at: Exercise location information; update tests
+ to differentiate output with and without locations.
+ Remove forward declarations of yylex and yyerror---caused errors
+ because default YYLTYPE not yet defined.
+ Change semantic actions to compute strings, rather than printing
+ them directly (to test proper passing of semantics values). Change
+ output to prefix notation and update test data and expected results.
+ (yylex): Track locations.
+ (stmtMerge): Return value rather than printing, and include arguments
+ in value.
+

+
+ Avoid warnings generated by GCC 2.95.4 when Bison is
+ configured with --enable-gcc-warnings.

+ yy::Stack::operator[] (unsigned),
+ yy::Stack::operator[] (unsigned) const,
+ yy::Slice::operator[] (unsigned),
+ yy::Slice::operator[] (unsigned) const):
+ Rename local vars to avoid warnings.
+ * tests/glr-regression.at (Improper handling of embedded actions
+ and $-N in GLR parsers): Remove unused local variable from yylex.
+ * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
+ (void) as arg when not pure, since we now assume C89 when building
+ Bison. Pacify GCC by using parameter.
