No. You might want to look into the x86 backend if there's maybe more tweaks

I tracked it down to the vector alignment configuration.
Apparently the vectorizer likes to build a "truth" vector, but is
perfectly happy to put it in a non-vector mode. Unfortunately that
causes TARGET_VECTOR_ALIGNMENT to be called with the non-vector mode,
which wasn't handled correctly.
I'm testing to see what happens with the reg_equal and reg_equiv
conversions, but we might be able to drop this patch.
