[PATCH] D97624: [X86] Improve SMULO/UMULO codegen for vXi8 vectors.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:27396
+                                     SelectionDAG &DAG,
+                                     SDValue *Low = nullptr) {
+  unsigned NumElts = VT.getVectorNumElements();
----------------
Isn't this really ISD::SMUL_LOHI/UMUL_LOHI ? Could the legalizer be taught to try and use as well?
