Move if (next_state->has_backref) into if (dfa->nbackref && next_state). Don't check for next_state != NULL twice. * posix/regcomp.c (peek_token): Use opr.ctx_type instead of opr.idx for ANCHOR. (parse_expression): Only call init_word_char if word context will be needed. * posix/bug-regex11.c (tests): Add new tests. * posix/tst-regex.c: Include getopt.h. (timing): New variable.

Add offsets, valid_raw_len, raw_len, raw_stop, mbs_allocated and offsets_needed fields. Change icase, is_utf8 and map_notascii type from int bitfield to unsigned char. (MBS_ALLOCATED, MBS_CASE_ALLOCATED): Remove. (build_wcs_upper_buffer): Change prototype to return int.

Reallocate buffers if build_wcs_upper_buffer converted too few bytes. Set valid_len to bufs_len only for single byte no translation and set in that case valid_raw_len as well. (re_string_realloc_buffers): Reallocate offsets if not NULL. Use mbs_allocated instead of MBS_ALLOCATED. Don't reallocate mbs_case. (re_string_construct_common): Initialize raw_len, mbs_allocated, stop and raw_stop. (build_wcs_buffer): Apply pstr->trans before mbrtowc instead of after it. Set valid_raw_len. Don't set mbs_case. (build_wcs_upper_buffer): Return REG_NOERROR or REG_ESPACE. Only use the fast path if !pstr->offsets_needed. Apply pstr->trans before mbrtowc instead of after it. If upper case character uses different number of bytes than lower case, goto to the slow path. Don't call towupper unnecessarily twice. Set valid_raw_len as well. Handle in the slow path the case if lower and upper case use different number of characters. Don't set mbs_case. (re_string_skip_chars): Use valid_raw_len instead of valid_len.

Check original offset against valid_raw_len instead of valid_len. Remove mbs_case handling. Adjust valid_raw_len together with valid_len. If is_utf8 and looking for tip context, apply pstr->trans first. If buffers start with partial multi-byte character, initialize mbs array as well if mbs_allocated. Check return value of build_wcs_upper_buffer. (re_string_peek_byte_case): New function. (re_string_fetch_byte_case): New function. (re_string_destruct): Use mbs_allocated instead of MBS_ALLOCATED. Don't free mbs_case. Free offsets. * posix/regcomp.c (init_dfa): Only check if charset name is UTF-8 if mb_cur_max == 6. * posix/regexec.c (re_search_internal): Initialize input.raw_stop as well.

Add new tests. * posix/regex_internal.c (re_string_allocate): Make sure init_len is at least dfa->mb_cur_max. (re_string_reconstruct): If is_utf8, don't fall back into re_string_skip_chars just because idx points into a middle of valid UTF-8 character. Instead, set the wcs bytes which correspond to the partial character bytes to WEOF. * posix/regexec.c (re_search_internal): Allocate input.bufs_len + 1 instead of dfa->nodes_len + 1 state_log entries initially. * posix/bug-regex20.c (main): Uncomment backwards case insensitive tests.
