+ * 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.
