Subject: [X86] AVX512: Specify compressed displacement for vmovntdqa
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7fc69597b78d96a42fb96f406b1f96232fe848dc;p=oota-llvm.git

[X86] AVX512: Specify compressed displacement for vmovntdqa

Use the max 64-bit element size with EVEX_CD8.  This should work since element
size is ignored for a full-vector access (FVM).
