--- Comment #5 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
The code is being vectorized in the "fails" dump and not being vectorized in
the "works" dump. This cannot be due to r249424, which does gimple folding on
some Power-specific built-ins, for this is a generic test case that makes no
use of such built-ins.
So either you have misidentified the revision responsible, or the code is
somehow being compiled differently so that vectorization happens in one case
and not the other.
