--- Comment #1 from Ilya Leoshkevich <iii at linux dot ibm.com> ---
Bisect points to r265398: combine: Do not combine moves from hard
registers.
I wonder what would be the best place to fix this? I was thinking about
making shrink-wrapping try harder by not limiting the processing to the
first basic block.
