For Kconfig, most features are discovered via testing a flag (e.g. `-fsanitize=kcfi`), but if the kernel needs `__has_feature()` anyway here, then that can also be used, yeah. For `rustc`, we can do similar tests too (and since we only support one kind of Rust compiler so far, versions checks can be a fallback option too). https://github.com/llvm/llvm-project/pull/121070 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
