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.
