--- Comment #2 from Peter Bergner <bergner at gcc dot gnu.org> ---
One interesting point is if we delete the "return result;" that is within the
then clause and fall thru to the end "return result;" with is logically
identical, then we get the code we want:

D256_add_finite:
        dcmpuq 7,4,6
        bnelr 7
        fmr 5,7
        fmr 4,6
        fmr 3,7
        fmr 2,6
        blr
