URL: https://github.com/llvm/llvm-project/commit/d6ae4bd686714d34969012fa273140e547606d81 DIFF: https://github.com/llvm/llvm-project/commit/d6ae4bd686714d34969012fa273140e547606d81.diff LOG: [Clang][NFC] Add tests for #56071 Theses tests were part of https://reviews.llvm.org/D140184, which is no longer necessary but preserving the tests seems useful. Thanks to Richard Trieu for providing these tests and the work on this PR.
