I'm not familar with KCFI. I find it's added by @samitolvanen in https://github.com/llvm/llvm-project/commit/e1c36bde0551977d4b2efae032af6dfc4b2b3936. I think you should triger it with attached test case. https://github.com/llvm/llvm-project/pull/117121 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
