These recently all grew a unique_ptr<TargetLoweringObjectFile> member in r221878. When anyone calls a virtual method of a class, clang-cl requires all virtual methods to be semantically valid. This includes the implicit virtual destructor, which triggers instantiation of the unique_ptr destructor, which fails because the type being deleted is incomplete. This is just part of the ongoing saga of PR20337, which is affecting Blink as well. Because the MSVC ABI doesn't have key functions, we end up referencing the vtable and implicit destructor on any virtual call through a class. We don't actually end up emitting the dtor, so it'd be good if we could avoid this unneeded type completion work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@222480 91177308-0d34-0410-b5e6-96231b3b80d8
