<pre>LLVM's style guide requires classes with vtables to have an out-of-line anchor
method (even it requires defining an unused synthetic one).
It would be nice if Clang had a warning to identify C++ classes without a
vtable anchor. To reduce noise, it might make sense to limit this to classes
with at least one out-of-line method, and then only fire the diagnostic when an
implementation of that method is seen.</pre>
