--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The difference is:
bb-slp-over-widen-1.c:33:1: note: Vectorizing an unaligned access.
in -mcpu=power8 or on e.g. x86_64 vs.
bb-slp-over-widen-1.c:33:1: missed: not vectorized: unsupported unaligned
store: *a_116(D)
bb-slp-over-widen-1.c:33:1: missed: not vectorized: bad data alignment in
basic block.
bb-slp-over-widen-1.c:33:1: note: removing SLP instance operations starting
from: *a_116(D) = _7;
with -mcpu=power7 or earlier. So, shall we:
