--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
Turning off PRE also allows it to pass but I guess it's the same as with SR=
A.
-fno-strict-aliasing also helps, -fno-ipa-modref doesn't.  I suspect bisect=
ion
isn't going to help much, but maybe it points to a small set of changes on =
the
testcase itself.=
