--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
It is the requirement. _mm*_loadu* are a special case, but the C __m128i type
itself requires 16-byte alignment. Just print __alignof__ (__m128i)...
Just use _mm*_loadu* if the load is from unaligned pointer, and recent versions
should when optimizing be able to optimize that case into a memory load in AVX
instruction.
