Agreed, that would the best solution here. > Or you could just forbid unprototyped functions in KCFI mode, If you don't > want to deal with the edge cases here (i.e. -Werror=strict-prototypes). I'm fine with this option too. However, I assume the author has a use case for KCFI in an existing code base, which uses unprototyped functions. https://github.com/llvm/llvm-project/pull/106677 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
