I think that was the question. The alignment comes from GET_MODE_ALIGNMENT. Some targets have strict alignment. 128-bit SSE spill/fill must be aligned. AVX supports unaligned spill/fill. We support GET_MODE_ALIGNMENT in our stack realignment work. Unaligned spill/fill in RA could be an interesting project.
