[PATCH] D70456: [Matrix] Add first set of matrix intrinsics and initial lowering pass.

[LuoYuanke via Phabricator via llvm-commits]

LuoYuanke added a comment.

I have the similar question on how to lower matrix intrinsics to some HW specific intrinsics/instruction. For example, X86 have the AVX512_VNNI feature (https://software.intel.com/sites/landingpage/IntrinsicsGuide/#expand=39,5370,5361,364,142,139,2210&text=vnni). It can perform dot product computation. But after matrix intrinsic is lowered to vector, it seems difficult to transform the vector operation to AVX512_VNNI intrinsic/instruction.
