URL: https://github.com/llvm/llvm-project/commit/89525cbf283f1ffeca1e007a06b29917a9eadc53 DIFF: https://github.com/llvm/llvm-project/commit/89525cbf283f1ffeca1e007a06b29917a9eadc53.diff LOG: [Clang] Add helper method to determine if a nonvirtual base has an entry in the LLVM struct This patch adds a helper method to determine if a nonvirtual base has an entry in the LLVM struct. Such a base may not have an entry if the base does not have any fields/bases itself that would change the size of the struct. This utility method is useful for other frontends (Polygeist) that use Clang as an API to generate code.
