I’m not sure why. As I said, they’ve been using Rust on ARM (as part of Firefox) for a long time; I’m not aware of them being unsatisfied with the current state.

I expect that the Rust project will end up benefiting from the extra interest though, and improving on the things above.

There has been very good progress on filling in the gaps to officially get Rust's AArch64 Linux toolchain triple to Tier-1 this year. We have CI for the Rust compiler test suites on native AArch64 silicon in a joint collaboration between Arm and the Rust lang core team and are converging on zero compiler test failures. Overall, we are pretty close to attaining Tier-1!

Is this public knowledge yet?

We haven't been very vocal about it just yet but all the bits to enable CI etc and the new t/compiler-arm Zulip stream are happening openly pretty much.

I'll be pinging all the relevant folks soon-ish (we're pushing out fixes to the last remaining compiler test suite failures this week).

I mean to keep you on CC as I did the last time!

Cool, I was dancing around it in this thread and recently because I wasn't sure how public it was :) I appreciate it!

Anything that runs Firefox also supports Rust as Rust is a core part of Firefox.
