Ah, I see! The semantics change. Now the option overwrites the default exclusions (vs extending them). I've implemented your requested changes and as per the suggestion [on discourse](https://discourse.llvm.org/t/rfc-teach-check-clang-tidy-py-the-filecheck-implicit-check-not-option/86480), I've split the tests using `split-file`. Closing this as completed. Feel free to re-open if I missed anything! Thanks for your feedback, @vbvictor - much appreciated! https://github.com/llvm/llvm-project/pull/95220 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
