One of the good things about putting Rust in android is that it's a great way to encourage AARCH64 support in the language.

  ARM themselves helped do the legwork here; aarch64-unknown-linux-gnu is already a Tier 1 supported platform thanks to their work https://doc.rust-lang.org/nightly/rustc/platform-support.html https://doc.rust-lang.org/nightly/rustc/platform-support.htm... But it is true that there are other aarch64-* triples that could move up (including aarch64-linux-android). Getting to Tier 1 is extremely hard due to the CI requirements.

    What's hard about CI? I would naively expect it to be just a virtual machine that you spin up and run jobs on, and Android doesn't seem hard to virtualize (Google's official tools even include this).

      For Android, specifically, that might be okay. I was speaking more generally. I am not sure if the compiler team has a specific "real hardware for tier 1" policy or not; we do use virtualization for some platforms, I believe. Probably a useful thing to clarify either way. There's also second order effects; the CI has to succeed on all tests on all platforms, which means that if your PR breaks on a platform you don't have expertise with, you need help, and we need to be prepared to give that help to you in a timely manner. Again, probably easier on Android, but a general barrier.
