--- Comment #7 from Tamar Christina <tnfchris at gcc dot gnu.org> ---
ok, managed to reproduce using a cross cc1.
This seems to happen because the vectorizer decides to use partial vectors to
vectorize the loop and the target picks a nonlinear induction step which we
can't support for early breaks.
The attached patch fixes it by rejecting these kind of inductions when partial
vectors are forced.
I'll submit the patch for when maintainers are back from holidays.
