    Hi,

I copy-pasted [this unit test](https://github.com/llvm/llvm-project/blob/ce7c828e085563f29451ec5fac9626c76ebf70ee/clang/test/CodeGenCXX/warn-all-padded-packed-packed-non-pod.cpp#L9) into a standalone .cpp file, and enabled `-Weverything`. To my surprise, no warnings are generated. Why is that?
