I support keeping `isPublic` because this check essentially looks for _classes with a misleading API_, and these functions are bugprone because they can mislead somebody who only looks at the public signature without reviewing the actual implementation -- and these don't apply for private methods. https://github.com/llvm/llvm-project/pull/132242 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
