[Amara Emerson via Phabricator via llvm-commits]

aemerson added inline comments.


================
Comment at: llvm/utils/TableGen/GlobalISelEmitter.cpp:4149
+  auto RC =
+      Target.getSuperRegForSubReg(Ty.getValueTypeByHwMode(), CGRegs, SubIdx);
+  return *RC;
----------------
`getSuperRegForSubReg()` seems to return an Optional, but here you get the value without checking if it's None.
