+
+ portability: use -DGNULIB_POSIXCHECK.
+ Reported by Eric Blake. See discussions at
+ <http://lists.gnu.org/archive/html/bug-bison/2009-09/msg00008.html>
+ and
+ <http://lists.gnu.org/archive/html/bug-gnulib/2009-10/msg00108.html>.
+ * HACKING (Release checks): Suggest -DGNULIB_POSIXCHECK.
+ * bootstrap.conf (gnulib_modules): Add all the printf modules
+ suggested by -DGNULIB_POSIXCHECK. Add realloc-posix as
+ suggested by -DGNULIB_POSIXCHECK for gnulib's own vasnprintf.c.
+ (excluded_files): Remove m4/printf-posix.m4.
+ * tests/atlocal.in (LIBS): As for LDADD in src/local.mk, add
+ lib/libbison.a so gnulib libraries can be linked.
+
+2009-12-15 Joel E. Denny <jdenny@clemson.edu>
+
+ gnulib: update for fix of fprintf-posix, which we'll use soon.
+ * etc/prefix-gnulib-mk (prefix): Adjust regex for make file
+ targets so that gnulib's new arg-nonnull.h and link-warning.h
+ are matched.
+ * gnulib: Update.
+
+2009-12-14 Joel E. Denny <jdenny@clemson.edu>
+
+ Enable assertion output and --disable-assert for configure.

+ cleanup.
+ * src/Sbitset.c (Sbitset__new_on_obstack): Use Sbitset instead
+ of char*.
+ (Sbitset__isEmpty): Use Sbitset instead of char*.
+ * src/Sbitset.h (Sbitset): Make it a pointer to unsigned char
+ instead of char. This helps to avoid casting errors.
+ (Sbitset__or): Use Sbitset instead of char*.
+
+2009-10-16 Joel E. Denny <jdenny@clemson.edu>
+
+ portability: don't assume 8-bit bytes.
+ That is, use CHAR_BIT and UCHAR_MAX instead of 8 and 0xff.
+ * src/Sbitset.h (Sbitset__nbytes): Here.
+ (Sbitset__byteAddress): Here.
+ (Sbitset__bit_mask): Here.

+ * src/complain.c (error_message): Move va_end from here...
+ (ERROR_MESSAGE): ... to here.
+
+2009-10-08 Joel E. Denny <jdenny@clemson.edu>

+ * TODO (Complaint submessage indentation): New.
+
+2009-10-04 Joel E. Denny <jdenny@clemson.edu>
+
+ Minor code cleanup.
+ * src/parse-gram.y: Clean up sorting of declarations.
+ Use types to simplify %printer declarations where possible.
+ Provide %printer for BRACKETED_ID and symbol.prec.
+ * src/symtab.c: Whitespace change.
+
+2009-10-04 Joel E. Denny <jdenny@clemson.edu>
+
+ tests: skip tests of file names that platform does not support.
+ Reported by Michael Raskin at
+ <http://lists.gnu.org/archive/html/bug-bison/2009-09/msg00001.html>.
+ * THANKS (Michael Raskin): Add.
+ * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Fix. Cygwin used
+ to fail at least for file names containing ":" or "\".
+
+2009-09-23 Joel E. Denny <jdenny@clemson.edu>
+
+ yysyntax_error: avoid duplicate lookahead collection.
+ Except when memory reallocation is required, this change
+ eliminates the need to invoke yysyntax_error twice and thus to
+ repeat the collection of lookaheads. It also prepares for
+ future extensions that will make those repetitions more
+ expensive and that will require additional memory management in
+ yysyntax_error. Finally, it fixes an obscure bug already
+ exercised in the test suite.
+ * data/yacc.c (yysyntax_error): Add arguments for message
+ buffer variables stored in the parser. Instead of size, return
+ status similar to yyparse status but indicating success of
+ message creation. Other than the actual reallocation of the
+ message buffer, import and clean up memory management code
+ from...
+ (yyparse, yypush_parse): ... here.
+ * tests/regression.at (parse.error=verbose overflow): No longer
+ an expected failure.
+
+2009-09-23 Joel E. Denny <jdenny@clemson.edu>
+
+ yysyntax_error: test memory management more.
+ * tests/atlocal.in (NO_WERROR_CFLAGS): New cpp macro.
+ * tests/regression.at (parse.error=verbose and
+ YYSTACK_USE_ALLOCA): New test group.
+ (parse.error=verbose overflow): New test group that reveals an
+ obscure bug. Expected fail for now.
+
+2009-10-04 Joel E. Denny <jdenny@clemson.edu>
+
+ benchmarks: use %debug consistently among grammars.
+ * etc/bench.pl.in (generate_grammar_triangular): Do not activate
+ %debug by default. It can affect the timings even if yydebug=0.
+ (generate_grammar_calc): For consistency with other grammars,
+ use YYDEBUG environment variable to set yydebug.
+
+2009-10-03 Joel E. Denny <jdenny@clemson.edu>
+
+ Remove dead code.
+ * src/symtab.c (symbol_pack): Here because every symbol's number
+ is always defined by this time.
+
+2009-10-03 Alex Rozenman <rozenman@gmail.com>
+
+ Add additional space after periods in NEWS.
+ * NEWS (2.5): here.
+
+2009-09-29 Joel E. Denny <jdenny@clemson.edu>
+
+ Use the correct conversion specifier for size_t.
+ Reported by Jim Meyering.
+ * src/Sbitset.h (SBITSET__INDEX__CONVERSION_SPEC): New, "zu"
+ because Sbitset__Index is size_t.
+ * src/Sbitset.c (Sbitset__fprint): Use it instead of %d.
+
+2009-09-27 Joel E. Denny <jdenny@clemson.edu>
+
+ tests: don't abuse AT_BISON_CHECK.
+ * tests/regression.at (parse-gram.y: LALR = IELR): Move
+ additional shell commands outside of AT_BISON_CHECK.
+
+2009-09-26 Joel E. Denny <jdenny@clemson.edu>
+
+ tests: check that parse-gram.y's IELR and LALR are identical.
+ * tests/atlocal.in (abs_top_srcdir): New shell variable.
+ * tests/regression.at (parse-gram.y: LALR = IELR): New test
+ group.

+
+ tests: clean up push.at test group titles.

+ because these are already under the banner "Push Parsing Tests".
+
+2009-09-12 Alex Rozenman <rozenman@gmail.com>
