Yes you're right - for gcc _mm_store1_pd is aligned (and there is a comment saying it must be), but _mm_store1_ps is unaligned. The intel intrinsics docs and msvc codegen both set both ps and pd versions to aligned store though. If you wish I can just do the pd fixes - we are alone in doing a extract + 2*movsd - the rest all use shufpd+movapd Suggestions for ps?
