[PATCH] D67874: Prefer AVX512 memcpy when applicable

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

Do we have a similar test for memset that should be updated?



================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:2156
+        if (Subtarget.hasBWI() && Subtarget.hasVLX())
+          return MVT::v64i8;
+        return MVT::v16i32;
----------------
VLX shouldn’t be needed. That’s only for 128/256 bit vectors.
