[PATCH] D118304: [Spill2Reg][7/9] MBB live-ins are now being updated.

[Guozhi Wei via Phabricator via llvm-commits]

Carrot added inline comments.


================
Comment at: llvm/lib/CodeGen/Spill2Reg.cpp:328
+      if (!MBB->isLiveIn(VectorReg))
+        MBB->addLiveIn(VectorReg);
+    }
----------------
If the reload and spill are in the same BB, like
```
bb6:
     spill  stack.0
     reload stack.0
```

does it adds VectorReg to LiveIn?
