lgtm, regardless of what we do with the external linkage bit.



================
Comment at: lib/Target/ARM/ARMAsmPrinter.cpp:840
+        StubSym = MachineModuleInfoImpl::StubValueTy(getSymbol(GV),
+                                                     !GV->hasInternalLinkage());
+    }
----------------
Maybe we should just pass `true` here instead of `!GV->hasInternalLinkage()`. We should never use .refptr stubs to access internal symbols, right? They will always be DSO local, and should be accessible with other means.

We don't even use `Stub.second.getInt()` in the generic AsmPrinter.cpp code that emits the stub globals.
