URL: https://github.com/llvm/llvm-project/commit/7b9f541c1edb24a676508906cfbcaaf228cc6a2e DIFF: https://github.com/llvm/llvm-project/commit/7b9f541c1edb24a676508906cfbcaaf228cc6a2e.diff LOG: [X86][SSE] Add tests for unpack(hop(),hop()) We should be able to convert these to permute(hop()) as we only ever use one of the ops from each hop.
