Martin Liška <marxin at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |WAITING Last reconfirmed| |2017-07-11 CC| |marxin at gcc dot gnu.org Ever confirmed|0 |1 --- 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 *)?
