--- Comment #12 from Uroš Bizjak <ubizjak at gmail dot com> ---
On the 4.9 branch, the patched compiler still results in the ICE. It looks like
branch and mainline are substantially different in recog.c infrastructure, and
proposed simple patch is ineffective on the branch.
Unassigning, a recog infrastructure expert (CC'd) is needed here.
