* posix/regex_internal.c (re_string_reconstruct): Avoid calling

	mbrtowc for very simple UTF-8 case.

2005-09-01  Paul Eggert  <eggert@cs.ucla.edu>

	* posix/regex_internal.c (build_wcs_upper_buffer): Fix portability
	bugs in int versus size_t comparisons.

2005-09-06  Ulrich Drepper  <drepper@redhat.com>

	* posix/regex_internal.c (re_acquire_state): Make DFA pointer arg
	a pointer-to-const.
	(re_acquire_state_context): Likewise.
	* posix/regex_internal.h: Adjust prototypes.

2005-08-31  Jim Meyering  <jim@meyering.net>

	* posix/regcomp.c (search_duplicated_node): Make first pointer arg
	a pointer-to-const.
	* posix/regex_internal.c (create_ci_newstate, create_cd_newstate,
	register_state): Likewise.
	* posix/regexec.c (search_cur_bkref_entry, check_dst_limits):
	(check_dst_limits_calc_pos_1, check_dst_limits_calc_pos):
	(group_nodes_into_DFAstates): Likewise.

	* posix/regexec.c (re_search_internal): Simplify update of
	rm_so and rm_eo by replacing "if (A == B) A += C - B;"
	with the equivalent of "if (A == B) A = C;".

2005-09-06  Ulrich Drepper  <drepper@redhat.com>

	* posix/regcomp.c (re_compile_internal): Change third parameter type
	to size_t.
	(init_dfa): Likewise.  Make sure that arithmetic on pat_len doesn't
	overflow.
	* posix/regex_internal.h (struct re_dfa_t): Change type of nodes_alloc
	and nodes_len to size_t.
	* posix/regex_internal.c (re_dfa_add_node): Use size_t as type for
	new_nodes_alloc.  Check for overflow.

2005-08-31  Paul Eggert  <eggert@cs.ucla.edu>

	* posix/regcomp.c (re_compile_fastmap_iter, init_dfa, init_word_char):
	(optimize_subexps, lower_subexp):
	Don't assume 1<<31 has defined behavior on hosts with 32-bit int,
	since the signed shift might overflow.  Use 1u<<31 instead.
	* posix/regex_internal.h (bitset_set, bitset_clear, bitset_contain):
	Likewise.
	* posix/regexec.c (check_dst_limits_calc_pos_1): Likewise.
	(check_subexp_matching_top): Likewise.
	* posix/regcomp.c (optimize_subexps, lower_subexp):
	Use CHAR_BIT rather than 8, for clarity.
	* posix/regexec.c (check_dst_limits_calc_pos_1):
	(check_subexp_matching_top): Likewise.
	* posix/regcomp.c (init_dfa): Make table_size unsigned, so that we
	don't have to worry about portability issues when shifting it left.
	Remove no-longer-needed test for table_size > 0.
	* posix/regcomp.c (parse_sub_exp): Do not shift more bits than there
	are in a word, as the resulting behavior is undefined.
	* posix/regexec.c (check_dst_limits_calc_pos_1): Likewise;
	in one case, a <= should have been an <, and in another case the
	whole test was missing.
	* posix/regex_internal.h (BYTE_BITS): Remove.  All uses changed to
	the standard name CHAR_BIT.
