+ 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 "\".

+
+ 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.

+
+ 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.

+
+ tests: don't abuse AT_BISON_CHECK.

+ 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.

+
+ lalr1.cc: syntax_error as exceptions.
+ It is common to use sort of factories in the user actions. These
+ factories may check some "syntactic" constraints that are not
+ enforced by the grammar itself. This is possible using YYERROR
+ within the action itself. Provide the user with a means to throw
+ a syntax_error exception.
+
+ * data/c++.m4 (b4_public_types_declare, b4_public_types_define):
+ Declare and define yy::parser::syntax_error.
