Comment:

 It seems we took this as far as it can go.  In summary: rust seems to work
 anecdotally approximately everywhere that we work anecdotally, and to work
 testedly where we work testedly.

 That's not a very excellent thing to say.

 It does. In fact, [https://en.wikipedia.org/wiki/Pentium_III SSE was
 introduced with the Pentium III], which was the
 
[https://en.wikipedia.org/wiki/P6_(microarchitecture)#From_Pentium_Pro_to_Pentium_III
 6th chip in the P6 (a.k.a. i686) microarchitecture series].

 In any case, the details of microarchitecture history are pretty moot
 here, because — in the current draft at least — we consider x86 platforms
 without SSE2 support to be "unsupported".  That is, if you expect Tor
 (with or without Rust) to run on your Pentium II, it's your job to get a
 clean patch to us.

 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=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.

 Those lamers think i686 supports SSE, so don't trust them.

Comment:

 It appears to me that all our "Target" and "Maintained" platforms are in
 either Tier 1 or 2 on the Rust Platform Support page. (https://forge.rust-
 lang.org/platform-support.html)

 Is there something I'm missing?

 We should go through
 
https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/SupportedPlatforms
 and determine how well these platforms are supported by Rust, and then
 document this information on
 https://trac.torproject.org/projects/tor/wiki/RustInTor.
