Update.
2004-12-07 Paolo Bonzini <bonzini@gnu.org> * posix/regexec.c (proceed_next_node): Simplify treatment of epsilon nodes. Pass the pushed node to push_fail_stack. (push_fail_stack): Accept a single node rather than an array of two epsilon destinations. (build_sifted_states): Only walk non-epsilon nodes. (check_arrival): Don't pass epsilon nodes to check_arrival_add_next_nodes. (check_arrival_add_next_nodes) [DEBUG]: Abort if an epsilon node is found. (check_node_accept): Do expensive checks later. (add_epsilon_src_nodes): Cache result of merging the inveclosures. * posix/regex_internal.h (re_dfastate_t): Add non_eps_nodes and inveclosure. (re_string_elem_size_at, re_string_char_size_at, re_string_wchar_at, re_string_context_at, re_string_peek_byte_case, re_string_fetch_byte_case, re_node_set_compare, re_node_set_contains): Declare as pure. * posix/regex_internal.c (create_newstate_common): Remove. (register_state): Move part of it here. Initialize non_eps_nodes. (free_state): Free inveclosure and non_eps_nodes. (create_cd_newstate, create_ci_newstate): Allocate the new re_dfastate_t here.
