Update.
* posix/regex_internal.h (re_token_type_t): Remove unused ALT, END_OF_RE_TOKEN_T and SUBEXP. Reorder values. Add OP_UTF8_PERIOD and EPSILON_BIT. (IS_EPSILON_NODE): Just test if EPSILON_BIT is set. (ACCEPT_MB_NODE): Return 1 for OP_UTF8_PERIOD as well. * posix/regex_internal.c (create_ci_newstate, create_cd_newstate): Handle OP_UTF8_PERIOD. (re_string_reconstruct): Set valid_len for single byte char searching with no translation and case sensitivity. * posix/regcomp.c (re_compile_fastmap_iter, calc_first): Handle OP_UTF8_PERIOD. (re_compile_internal): Don't call optimize_utf8 if preg->translate != NULL. (optimize_utf8): Remove BACK_SLASH case. Transform OP_PERIOD into OP_UTF8_PERIOD if the searching can be optimized. (parse_bracket_exp): Don't create SIMPLE_BRACKET if it doesn't have any bits set and COMPLEX_BRACKET is used. * posix/regexec.c (transit_state_mb): Fix comment typo. (group_nodes_into_DFAstates, check_node_accept): Handle OP_UTF8_PERIOD. (check_node_accept_bytes): Likewise. Reorder slightly so that re_string_char_size_at and re_string_elem_size_at are called only when needed. * posix/bug-regex20.c (BRE, ERE): Define. (tests): Use them to make lines shorter. Expect . to be optimized. Add lots of new tests. (main): Run (ATM just case sensitive) test with backwards searching as well. 2003-11-18 Jakub Jelinek <jakub@redhat.com>
