Comment (by isis):

 Replying to [comment:2 nickm]:
 > 64-bit android was mentioned on IRC; what's the status there?  Also, I
 think the current tier 2 guarantees are a bit scary, though they are
 comparable to our own "maintained" verbiage.

 So [https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound the Firefox
 Treeherder] (their CI server) is running tests for aarch64 for Android 5.0
 (grep for "Android 5.0 AArch64 opt", e.g.
 [https://treeherder.mozilla.org/#/jobs?repo=mozilla-
 inbound&selectedJob=110926031 this job]). I'm told by the people on the
 Servo team that all of the tests are running with Rust enabled. Since
 Firefox is targeting aarch64, there are discussions and general consensus
 that Rust needs to lift it to Tier 1 support.

 > In particular, is the expectation that Tier 2 will generally work well,
 and that the unit tests, when run, will pass?  Or is Tier 2 full of some
 platforms that work and some that don't?

 Tier 2 is supposed to build, but the tests are not automatically run.
 Anecdotally, I (and other people on our team, like ahf, and Firefox/Servo
 devs, and developers from a company which is using some of my Rust crypto
 on an HSM) have successfully run the unit tests on Tier 2 platforms
 without a hitch.
