--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note that if that is fixed we still fail vectorization with
t.C:8:21: missed: not vectorized: relevant stmt not supported: _16 = mask_26
<< s_7;
t.C:18:27: missed: bad operation or unsupported loop bound.
I have a fix for that. But in the end the issue is weak handling of vectorized
nested cycles in general.
