================
Comment at: llvm/lib/IR/Value.cpp:717
       // CanBeNull flag.
-      DerefBytes = DL.getTypeStoreSize(GV->getValueType());
+      DerefBytes = DL.getTypeStoreSize(GV->getValueType()).getKnownMinSize();
       CanBeNull = false;

>From the LangRef:

So I think this can use getFixedSize().
