--- Comment #5 from Uroš Bizjak <ubizjak at gmail dot com> --- (In reply to Hongtao.liu from comment #2) > Need to add define_insn for movp2qi/movp2hi? Yes, this is needed to cover some corner cases. Please see attachment 49114. However, the patch assumes that avx512vp2intersect implies mavx512dq, otherwise there is no direct QImode move from mask register to memory available.
