I'm doing some fuzzer related proejct. In the llvm's sanitizer coverage, it allows __attribute__((no_sanitize("coverage"))) to ignore certain functions. I tried to search for it in Rust, it seems for now Rustc only allows few of attributes? Can you give me more reference about this problem?
You can use #[no_coverage] with the no_coverage unstable feature as replacement for __attribute__((no_sanitize("coverage"))) in C. Note that all __attribute__ attributes are defined in clang, not LLVM. As such rustc has to manually implement them. It can't reuse clang's support.
