	* posix/runptests.c (main): Make errors fatal.
	* posix/PTESTS: One test in GA135 and GA136 check functionality
	which seems not guaranteed.

2003-11-25  Jakub Jelinek  <jakub@redhat.com>

	* posix/regexec.c (re_search_internal): If prune_impossible_nodes
	returned REG_NOMATCH, set match_last to -1.  Don't initialize
	pmatch[0] needlessly.  Fix comment.
	(prune_impossible_nodes): Don't segfault on NULL state_log entry.
	(set_regs): Fix comment.
	* posix/regcomp.c (parse_bracket_exp): Only set has_plural_match
	if adding both SIMPLE_BRACKET and COMPLEX_BRACKET.
	(build_charclass_op): Set has_plural_match if adding both
	SIMPLE_BRACKET and COMPLEX_BRACKET.
	* posix/bug-regex11.c (tests): Fix register values for one commented
	out test.  Add new tests.

	* posix/regex_internal.c (re_string_allocate): Make sure init_len
	is at least dfa->mb_cur_max.
	(re_string_reconstruct): If is_utf8, don't fall back into
	re_string_skip_chars just because idx points into a middle of
	valid UTF-8 character.  Instead, set the wcs bytes which correspond
	to the partial character bytes to WEOF.
	* posix/regexec.c (re_search_internal): Allocate input.bufs_len + 1
	instead of dfa->nodes_len + 1 state_log entries initially.
	* posix/bug-regex20.c (main): Uncomment backwards case insensitive
	tests.

	* posix/bug-regex20.c: Correct invalid UTF-8 sequences.

	* posix/regex_internal.h (re_token_type_t): Remove unused ALT,
	END_OF_RE_TOKEN_T and SUBEXP.  Reorder values.  Add OP_UTF8_PERIOD
	and EPSILON_BIT.
	(IS_EPSILON_NODE): Just test if EPSILON_BIT is set.
	(ACCEPT_MB_NODE): Return 1 for OP_UTF8_PERIOD as well.
	* posix/regex_internal.c (create_ci_newstate, create_cd_newstate):
	Handle OP_UTF8_PERIOD.
	(re_string_reconstruct): Set valid_len for single byte char searching
	with no translation and case sensitivity.
	* posix/regcomp.c (re_compile_fastmap_iter, calc_first): Handle
	OP_UTF8_PERIOD.
	(re_compile_internal): Don't call optimize_utf8 if preg->translate
	!= NULL.
	(optimize_utf8): Remove BACK_SLASH case.
	Transform OP_PERIOD into OP_UTF8_PERIOD if the searching can be
	optimized.
	(parse_bracket_exp): Don't create SIMPLE_BRACKET if it doesn't have
	any bits set and COMPLEX_BRACKET is used.
	* posix/regexec.c (transit_state_mb): Fix comment typo.
	(group_nodes_into_DFAstates, check_node_accept): Handle
	OP_UTF8_PERIOD.
	(check_node_accept_bytes): Likewise.  Reorder slightly so that
	re_string_char_size_at and re_string_elem_size_at are called
	only when needed.
	* posix/bug-regex20.c (BRE, ERE): Define.
	(tests): Use them to make lines shorter.  Expect . to be
	optimized.  Add lots of new tests.
	(main): Run (ATM just case sensitive) test with backwards searching
	as well.

2003-11-17  Jakub Jelinek  <jakub@redhat.com>

	* posix/regcomp.c (optimize_utf8): Optimize multi-byte chars as
	well.
	* posix/bug-regex20.c (tests): Add new tests.  Multi-byte char
	followed by dup operator is expected to be optimized.

	* posix/regexec.c (check_node_accept_bytes): Move nrules and j
	variables to the block where they are only used, initialize
	nrules only immediately before using it.
