Today we publish target builds for mips and mipsel, and have no support for mips64el. All three of these are or will soon be supported by Debian and Fedora.

  • mips
  • mipsel
  • mips64el

I managed to produce functional rustcs for the mips and mipsel targets. I've sent the required changes to the rust-buildbot repository (rust-lang-deprecated/rust-buildbot#121).

bors added a commit that referenced this issue Sep 2, 2016

@bors
Auto merge of #36024 - japaric:mips64, r=alexcrichton 
add mips64-gnu and mips64el-gnu targets

With this commit one can build no_core (and probably no_std as well)
Rust programs for these targets. It's not yet possible to cross compile
std for these targets because rust-lang/libc doesn't know about the
mips64 architecture.

These targets have been tested by cross compiling the "smallest hello"
program (see code below) and then running it under QEMU.

``` rust

extern {
    fn puts(_: *const u8);
}

fn start(_: isize, _: *const *const u8) -> isize {
    unsafe {
        let msg = b"Hello, world!\0";
        puts(msg as *const _ as *const u8);
    }
    0
}

trait Copy {}

trait Sized {}
```

The cabi stuff is likely wrong. I just copied cabi_mips source and changed some `4`s to `8`s and `32`s to `64`s. It was enough to get libc's `puts` to work but I'd like someone familiar with this module to check it.

Complications last night prevented these nightlies from going out, hopefully tonight though!
