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

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

+
+ * 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.
+
* posix/regex_internal.h (re_sub_match_top_t): Remove unused member
next_last_offset.
(struct re_dfa_t): Remove unused member states_alloc.
