        * config/pa/pa.md (decrement_and_branch_until_zero): Use `Q' constraint
        instead of `m' constraint.  Likewise for unnamed movb comparison
        patterns using reg_before_reload_operand predicate.
        * config/pa/predicates.md (reg_before_reload_operand): Tighten
        predicate to reject register index and LO_SUM DLT memory forms
        after reload.
