[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/Target/X86/X86ISelDAGToDAG.cpp:5665
+        SDValue TruncN1 = CurDAG->getConstant(
+            C.trunc(NewVT.getScalarSizeInBits()).getZExtValue(), dl, MVT::i32);
+        insertDAGNode(*CurDAG, SDValue(Node, 0), TruncN1);
----------------
Shouldn't the type for the constant be NewVT?
