[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added a comment.

I hope it passes precheckin.



================
Comment at: lib/Target/AMDGPU/SILowerI1Copies.cpp:695
+    MI = MRI->getUniqueVRegDef(Reg);
+    if (MI->getOpcode() != AMDGPU::COPY)
+      break;
----------------
MI can be null technically.
