--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
The issue seems to be that if-conversion isn't done:
Can not ifcvt due to multiple exits
maybe my patched dev tree arrives with a different CFG here (no switches
into ifcvt). I don't think if-conversion was adjusted when the vectorizer
gained early exit vectorization - if-conversion shouldn't for example
predicate with the exit condition and it should leave those conditions
and exits around.
