## Tier 2.5
Tier 2.5 platforms can be thought of as "guaranteed to build", but without
builds available through `rustup`. Automated tests are not run so it's not
guaranteed to produce a working build, but platforms often work to quite a good
degree and patches are always welcome! Specifically, these platforms are
required to have each of the following:

* Automated building is set up, but may not be running tests.
* Landing changes to the `rust-lang/rust` repository's master branch is gated on
platforms **building**. For some platforms only the standard library is
compiled, but for others `rustc` and `cargo` are too.

**This status is accidental: no new platforms should reach this state**

are not built or tested automatically, and may not work. Official builds are
