[PATCH] D136832: [VectorUtils] Add getShuffleDemandedElts helper

[Sanjay Patel via Phabricator via llvm-commits]

spatel added inline comments.


================
Comment at: llvm/lib/Analysis/VectorUtils.cpp:432-434
+bool llvm::getShuffleDemandedElts(int SrcWidth, ArrayRef<int> Mask,
+                                  const APInt &DemandedElts, APInt &DemandedLHS,
+                                  APInt &DemandedRHS, bool AllowUndefElts) {
----------------
Can we assert that SrcWidth == DemandedLHS.getBitWidth() == DemandedRHS.getBitWidth() ?
