A word of warning on this. It uses a custom fork of LLVM/Clang/Rust which adds support for a new architecture. The tooling that sets up this environment has failed in obscure ways each time I’ve attempted to set up and build one of their own hello world samples.

The llvm patches were up streamed a few weeks ago, so that should help significantly once it trickles into releases of the actual compilers.
