--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I will have a look - the change should not have resulted in (major) code
generation changes.  Some effects result in slightly different CFG in some
cases (somewhat mitigated with r13-1503-gc3d2600cfb476e which I will
cherry-pick for investigating).
