--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Actually, it seems the unaligned load splitting is there because of
sandybridge?
DEF_TUNE (X86_TUNE_AVX256_UNALIGNED_LOAD_OPTIMAL, "256_unaligned_load_optimal",
~(m_NEHALEM | m_SANDYBRIDGE | m_GENERIC))
Though the Nehalem in there is weird, there weren't any Nehalem CPUs with AVX
support, right? And if it is just something for Sandybridge which doesn't
support AVX2, then either for AVX2 we should use a different tuning parameter
(which might be set for all CPUs?), or do the ISA specific generic tuning.
