[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/CodeGen/GlobalISel/CombinerHelper.cpp:1686
+    Register TmpReg =
+        Builder.buildTrunc(LLT::scalar(Dst0Ty.getSizeInBits()), SrcReg)
+            .getReg(0);
----------------
can use auto and avoid .getReg(0)
