     IRBuilder<> IRB(&I);
     Type *ShadowTy = getShadowTy(&I);
     unsigned Width =
----------------
ShadowTy is now an unused variable. Delete to avoid a compile warning.


================
Comment at: llvm/lib/Transforms/Scalar/LowerMatrixIntrinsics.cpp:337
       Value *Vec = isColumnMajor() ? getColumn(J) : getRow(I);
       Value *Undef = UndefValue::get(Vec->getType());
       return Builder.CreateShuffleVector(
----------------
`Undef` is now an unused variable. Delete to avoid a compile warning.
