I'm one of Debian's maintainers in Debian Ports and I maintain Debian unstable
on older and more obscure architectures such as alpha, hppa, m68k, sh4 and sparc64.
Of all the architectures in Debian, there are currently four architectures that
don't support rustc. Those are alpha, hppa, m68k and sh4 [1]. For m68k, the
situation is special as both LLVM and rustc already support m68k but with Linux
still defaulting to 16-bit alignment on this architecture [2], building LLVM and
rustc is currently not possible. I'm working on a switch to 32-bit alignment
though which is default for NetBSD/m68k and also what specified in the official
SysV ELF ABI documentation.
In general, I'm not against introducing Rust support into existing projects. However,
I wished projects would be a little more patient until either the GCC codegen in
rustc called rustc_codegen_gcc [3] or the Rust frontend in GCC have become ready
for prime time.
My hope would be that more talented Rust developers would help support the two
GCC Rust projects so that these become ready for prime time sooner and that one
of the last blockers for introducing the Rust language across a lot of open source
projects would go away.
I'm not an expert with the Non-Stop operating system, but I could imagine that
a working Rust frontend in GCC would ease porting the Rust language to that
platform as well.
Cheers,
Adrian
