I'm curious what rust features require runtime support; there's some VTable and exception handling stuff we may have to do for C++, but I've got no idea how much is handled by rust's frontend.

I still need to figure out what already works and what doesn't - I'm planning to spent some time on that ...

Good news also on rust frontend work :)

After my first experiment with rust + llvm-mos I decided to go a step further and try to add real mos target triple to rust. This should allow to use standard rust tools (like cargo) to build some no_std programs. Creating mos-unknown-none triplet was quite ...

We'll probably get some degree of C++ support "for free"
Even more: thanks to your amazing work I was able to compile first ever Rust program for 6502 and test it on Atari!

To reproduce you need working rustc, llvm-mos and llvm-mos-sdk. Create following files:
