It looks like they intended to keep "cyclone" as a legacy option, but removed it from the list of subtarget features. This created a flood of warnings when targeting aarch64-apple-ios, and probably also created incorrectly optimized artifacts.

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @estebank (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

I am nominating this for stable backport, though it feels like we may want to opt to not do so. I believe this commit is in current beta.

See discussion on #74427 as well.

discussed in T-compiler meeting, declining to backport.

Backporting changes that affect codegen like this are scary and the drawbacks of not backporting it doesn't seem really bad.
