For many years now I've been eargerly waiting for a language that can compile it's own compiler to wasm/wasi. I've talked with the guy who made the llvm to wasm demo (sadly that project has quickly been going nowhere). I've talked to some rust groups about compiling a minimal subset of a rust compiler to wasm. I've talked with some people from V-lang, etc.
So my question is, how unrealistic is it for cranelift to compile itself to wasm (a module function with IR input and wasm-bytes output)? "Unrealistic" as-in; is there unavoidable multithreading, or raw assembly, etc in cranelift that would be a show-stopper for compiling it to WASM.
Thanks!

Hi @jeff-hykin -- this use-case would mainly depend on support for generating Wasm bytecode, which we previously discussed a bit in #2566. I think that while it's not totally unrealistic, it's a major undertaking: Wasm as an ISA is very different from our current target architectures in several important ways (stack machine, unlimited "registers" (locals) hence maybe no or only simple regalloc, functions are a first-class machine feature rather than software-managed via stack conventions, structured control flow, etc). I'd encourage you to read over that thread for ideas and background.

Oh I'm actually embarrassed to admit I didn't realize WASM/WASI wasn't a cranelift backend. And I was just reading the internals of the IR last week :sweat_smile: Thanks for the pointer to that thread. That'll certainly resolve this issue for now.
I suppose I just associated wasmtime/bytecode-alliance/cranelift so much I had just always assumed WASM was a cranelift backend.
