I removed the hardcoded attributes from this patch and added my local fix as a demonstration - it extends the validation logic to expect that builtins and the special asprintf-like functions will get the attribute eventually. Other ways to fix would be to move validation or addition of implicit attributes around, which is a bigger structural change. Please let me know what you think, thanks! https://github.com/llvm/llvm-project/pull/194003 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
