This first regressed with:

http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=190492

into:

        movsd   %xmm0, -8(%rsp)

        addsd   %xmm2, %xmm0

and then we regress again with:

http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=190847

into:

        addsd   %xmm0, %xmm2

        movsd   %xmm0, -8(%rsp)

        movapd  %xmm2, %xmm0
