Update.
2004-01-02 Jakub Jelinek <jakub@redhat.com> * posix/regex_internal.c (re_node_set_insert): Remove unused variables. * posix/regex_internal.h (re_dfa_t): Add syntax field. * posix/regcomp.c (parse): Initialize dfa->syntax. * posix/regexec.c (acquire_init_state_context, prune_impossible_nodes, check_matching, check_halt_state_context, proceed_next_node, sift_states_iter_mb, sift_states_backward, update_cur_sifted_state, sift_states_bkref, transit_state, transit_state_sb, transit_state_mb, transit_state_bkref, get_subexp, get_subexp_sub, check_arrival, expand_bkref_cache, build_trtable): Remove preg argument, add dfa argument instead and remove dfa = preg->buffer initialization in the body. Adjust all callers. (check_node_accept_bytes, group_nodes_into_DFAstates, check_node_accept): Likewise. Use dfa->syntax instead of preg->syntax. (check_arrival_add_next_nodes): Remove preg argument. * posix/regex_internal.h (re_match_context_t): Make input re_string_t instead of a pointer to it. * posix/regex_internal.c (re_string_construct_common): Don't clear pstr here... (re_string_construct): ... but only here. * posix/regexec.c (match_ctx_init): Remove input argument. Don't initialize fields to zero. (re_search_internal): Move input into mctx.input. (acquire_init_state_context, check_matching, check_halt_state_context, proceed_next_node, clean_state_log_if_needed, sift_states_bkref, sift_states_iter_mb, transit_state, transit_state_sb, transit_state_mb, transit_state_bkref, get_subexp, check_arrival, check_arrival_add_next_nodes, check_node_accept, extend_buffers): Change mctx->input into &mctx->input and mctx->input->field into mctx->input.field. 2004-01-02 Jakub Jelinek <jakub@redhat.com> Paolo Bonzini <bonzini@gnu.org> * posix/regex_internal.h (re_const_bitset_ptr_t): New type. (re_string_t): Add newline_anchor, word_char and word_ops_used fields. (re_dfa_t): Change word_char type to bitset. Add word_ops_used field. (re_string_context_at, re_string_reconstruct): Remove last argument. * posix/regex_internal.c (re_string_allocate): Initialize pstr->word_char and pstr->word_ops_used. (re_string_context_at): Remove newline_anchor argument. Use input->newline_anchor instead, swap && conditions. Only use IS_WIDE_WORD_CHAR if input->word_ops_used != 0. Use input->word_char bitmap instead of IS_WORD_CHAR. (re_string_reconstruct): Likewise. Adjust re_string_context_at caller. * posix/regexec.c (acquire_init_state_context, check_halt_state_context, transit_state, transit_state_sb, transit_state_mb, transit_state_bkref, check_arrival, check_node_accept): Adjust re_string_context_at and re_string_reconstruct callers. (re_search_internal): Likewise. Set input.newline_anchor. (build_trtable): Use dfa->word_char bitmap instead of IS_WORD_CHAR. * posix/regcomp.c (init_word_char): Change return type to void. Set dfa->word_ops_used. (free_dfa_content): Don't free dfa->word_char. (parse_expression): Remove error handling for init_word_char.
