--- Comment #13 from Allan Jensen <linux at carewolf dot com> --- The question is if the unaligned store is still slow on Excavator and Ryzen which support AVX2. As far as I understand the bulldozer architectures just prefer split AVX because it was basically emulating them with 128-bit micro-ops anyway.
