Hi John Paul,

The variations we have so far were intended to showcase the Rust
support in several major architectures, rather than cover everything.
But as long as LLVM (& the kernel, i.e. ClangBuiltLinux) supports the
target (and as long there are no compiler/toolchain issues), you
should be able to try it.

Mostly -- there is also `rust/kernel/c_types.rs` and you may need to
tweak `rust/compiler_builtins.rs`, but not much more.

Note that for the target spec files, the short-term plan is to
generate dynamically the target spec file according to what the
architecture requests, instead of using these static files. Longer
term, we need a Rust-stable way to setup custom targets from upstream
`rustc` (though it is not clear yet how it will look, e.g. it could be
via command-line flags).

Cheers,
Miguel
