--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
As the signature of the intrinsic is:
_mm_cmpestri (__m128i __X, int __LX, __m128i __Y, int __LY, const int __M)
And as __m128i variables are aligned to 16 bytes boundary, thus then it should
not be problem? Or can be problem if one casts an unaligned memory to (__m128i
*)?
