[PATCH] D24956: [SelectionDAG] Add expansion and promotion of [US]MUL_LOHI

[Simon Pilgrim via llvm-commits]

RKSimon added inline comments.


================
Comment at: lib/CodeGen/SelectionDAG/TargetLowering.cpp:3035
+      !OnlyLegalOrCustom || isOperationLegalOrCustom(ISD::UMUL_LOHI, HalfVT);
+  unsigned OuterBitSize = VT.getSizeInBits();
+  unsigned InnerBitSize = HalfVT.getSizeInBits();
----------------
If this is going to start being used by vectors, shouldn't these getSizeInBits() calls be replaced with getScalarSizeInBits()?
