Topic: Compiling a DSL to WASM using Cranelift?

Hello! I'm wondering if it's possible to use cranelift as a backend to compile my language to WASM.

If I interpret this correctly that means it's not possible right?
Is it planned to be supported in the future?

(just for context, I'm making a live-coding audio synthesizer & would like to make an online playground)

Ooh I just found the related issue: https://github.com/bytecodealliance/wasmtime/issues/2566
Before I searched for "wasm backend" on github but not "webassembly backend" and found nothing :sweat_smile:
So I guess it's wanted but not prioritized, got it
