This works but is a bit subtle -- usually we'd have `-verify` in all of the `RUN` lines and we'd use a different prefix for these and we ensure there are no diagnostics with the diagnostics verifier, along these lines. https://github.com/llvm/llvm-project/pull/74440 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
