2004-02-29 Paolo Bonzini <bonzini@gnu.org> * posix/regexec.c (transit_state): Don't handle state == NULL. Move state log and backreference management... (merge_state_with_log): ... to this function. (find_recover_state): New function. (check_matching): Use find_recover_state to get a non-NULL state when an invalid state is reached. Compute the amount of initial characters to be skipped less conservatively when multi-byte character sets are in use. Do not check dfa->nbackref if the state log is NULL. Initialize err. (acquire_init_state_context): Expect err to be initialized. Fix spacing. 2004-03-05 Jakub Jelinek <jakub@redhat.com> * sysdeps/sparc/sparc32/elf/start.S: Handle PIEs. * sysdeps/sparc/sparc64/elf/start.S: Likewise.
