I don't think it's that simple. AVR was merged into LLVM, but I think you'd be hard pressed to get either rust or swift running on it right now. > So you can use any backend LLVM does.. theres a little runtime friction in porting a small Swift runtime to the target More than a little friction, I would think. I actually 'trust' the support if the language declares that they are going to support it. For example, Rust has said they will support the wasm target as first class.
