        * mn10300/mn10300.c (notice_update_cc): Enable this code.
        * mn10300/mn10300.h (CC_OVERFLOW_UNUSABLE): Define.
        * mn10300/mn10300.md (tstsi): Use "set_zn_c0" instead of "set"
        for cc status.
        (addsi3 pattern): Break "inc" into two different alternatives
        since "inc dn" sets cc0, but "inc an" does not.
        (multiply and divide patterns): Fix cc status.
        (bCC, inverted bCC): Restore any comparison which needs the
        overflow bits when CC_OVERFLOW_UNUSABLE is set.
        (zero and sign extensions): Fix cc status.
        (movm_store): Likewise.
