[PATCH] D97811: [GlobalISel] Handle non-multiples of the base type in narrowScalarAddSub

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/CodeGen/GlobalISel/LegalizerHelper.cpp:4523
+    Register DstReg =
+        MRI.createGenericVirtualRegister(MRI.getType(Src1Regs[i]));
     Register CarryOut = MRI.createGenericVirtualRegister(LLT::scalar(1));
----------------
Why do you need to getType here? It should be the same as NarrowTy?
