Update.
2002-11-27 Isamu Hasegawa <isamu@yamato.ibm.com> * posix/regcomp.c (parse_expression): Set the bit since the back reference is used in the regular expression. * posix/regex_internal.c (re_node_set_init_1): Make it clean in case of malloc failure. (re_node_set_init_copy): Likewise. * posix/regex_internal.h (state_array_t): New structure. (re_sub_match_last_t): Likewise. (re_sub_match_top_t): Likewise. (re_match_context_t): Add new members. (re_dfa_t): Likewise. * posix/regexec.c (re_search_internal): Invoke prune_impossible_nodes to check the matching is really correct, and retry if failed. Move the routin pruning the impossible nodes from here, ... (prune_impossible_nodes): To this function. (check_matching): Invoke check_subexp_matching_top, and replace redundant checking with transit_state_bkref invocation. (proceed_next_node): Replace strncmp with memcmp. Reported by Paolo Bonzini <bonzini@gnu.org>. (update_cur_sifted_state): Remove search_subexp invocation. (search_subexp): Remove this function. (check_dst_limits_calc_pos): Use search_cur_bkref_entry for optimization. (sift_states_bkref): Use search_cur_bkref_entry for optimization. Remove unused invocation of match_ctx_add_entry. (transit_state): Invoke check_subexp_matching_top. (check_subexp_matching_top): New function. (transit_state_bkref): Remove unused array. Merge transit_state_bkref_loop. (transit_state_bkref_loop): Use get_subexp instead of sift_states_backward. Use search_cur_bkref_entry for optimization. Merge this function to transit_state_bkref. (get_subexp): New function. (get_subexp_sub): Likewise. (find_subexp_node): Likewise. (check_arrival): Likewise. (check_arrival_expand_ecl): Likewise. (check_arrival_expand_ecl_sub): Likewise. (expand_bkref_cache): Likewise. (match_ctx_init): Initialize new members. (match_ctx_clean): New function. (match_ctx_free): Release new members. (match_ctx_free_subtops): New function. (match_ctx_add_entry): Fix indent. (search_cur_bkref_entry): New function. (match_ctx_add_subtop): Likewise. (match_ctx_add_sublast): Likewise.
