7 sourcesAnd unofficial "Tier 5" Rust Target is... for Commodore-64:

It works, and builds binaries that are ready to be executed by Vice emulator.
In Unofficial "Tier 4" Rust Target for older Windows versionsFor Commodore the computer, there is a Rust and LLVM fork for MOS:

It's able to generate binaries that are executed on C64. Tried it on the
emulator, and it's pretty wild that it allows to write Rust for such old
machines.
I wish Rust was available on Amigas. I know there is a Motorola 68000
backend for LLVM (although probably without the support for HUNK
format), so probably a significant backend is already done, but I'm not
knowledgable about the LLVM infrastructure enough to be able to wire up
things together.
In Roguecraft Devs on Developing for Amiga in 2024rust the compiler, hell no.
But there is an llvm-mos project to generate 6502 code and that can be used to cross compile rust code.

In Ruby on the Apple II (2019) [video]This is a super fun project to play around with. I'm currently trying to build a C64 sprite multiplexer in mostly straight C++ using LLVM-MOS and while it's definitely not going to be the most optimized multiplexer out there, I'm finding it mostly adequate performance-wise.
Whereas it's probably a long way away from being able to use this for democoding due to the mostly cycle-accurate nature of the effects, for creating homebrew games and utilities this is really quite suitable: write high-level logic in C or C++ (or any language supported by LLVM really) and sprinkle in some inline assembly here and there for the really performance critical parts.
The code that is being generated is already quite good and (on first glance) looks better than what's coming out of cc65, for instance.
There's also rust-mos which uses LLVM-MOS to compile Rus

t code. It unfortunately still has some issues (e.g. [1]) but that is looking really promising as well.
Kudos to all involved :)

This fork is handy for that. It’s fun to play with, but you need to do a decent amount yourself to get it set up.
