Test case?
================
Comment at: lib/CodeGen/CGExprCXX.cpp:93
+
+ EmitTypeCheck(CodeGenFunction::TCK_MemberCall,
+ CallLoc, This, C.getRecordType(DD->getParent()));
----------------
Is it correct to emit a type check at this point? Looking at [0] it looks like this function is only called from the Microsoft C++ ABI after we have already resolved the virtual function pointer.
