Could RUST support CFI on stabilized builds?

[yuhui518]

I find that LLVM CFI and cross-language LLVM CFI (and LLVM KCFI and cross-language LLVM KCFI) are available on nightly builds of the Rust compiler.The address is https://bughunters.google.com/blog/4805571163848704/llvm-cfi-and-cross-language-llvm-cfi-support-for-rust.
And CFI docs say RUST could support CFI with option -fsanitize=cfi.
So, how can I follow the correct steps to enable RUST's CFI. Which build version that nightly or stabilized should I choose?

Unfortunately LLVM CFI and cross-language LLVM CFI aren't supported on stable builds yet. To use these, you'll need to use a nightly build: https://rust-lang.github.io/rustup/concepts/channels.html.

To follow the work on stabilizing the sanitizers (along with LLVM CFI and cross-language LLVM CFI), see the tracking issue for stabilizing the sanitizers at #123615, and also our roadmap at https://hackmd.io/@rcvalle/S1Ou9K6H6.

Closing in favour of the tracking issue.
