A friend of mine worked on https://github.com/libriscv/godot-sandbox https://github.com/libriscv/godot-sandbox Which uses libriscv as the sandboxed compute target. IIRC They tried for years to get a wasm backend to work and eventually abandoned it citing, among other reasons, something about how it was difficult to wrangle a stack machine with a register machine. I don’t really see what benefits wasm runtimes have over something like libriscv which is very fast and maps more closely to hardware.

First I've heard of libriscv. What exactly is it? A wasm alternative that uses RISCV byte code?

  Wasm and risc-v are totally different. Wasm is an assembly like language for high performance computing in the browser And risc-v is an arm-like instruction set for physical CPUs. Wasm has a lot of runtimes which are basically VMs that run wasm. Libriscv is a very small very vast VM that runs riscv assembly.

Funny you mention that because mini-moonbitlang seems to be using libriscv! https://github.com/moonbitlang/minimoonbit-public https://github.com/moonbitlang/minimoonbit-public So, maybe not the official compiler but something else is already using it?
