JIT compiler support with #[no_std] for embedded devices ?

[LordCasser]

There is just a use case, I'd like to make the wasm JIT compiler a part of VM-OS.

You'll find some more discussion about this here, but I'll also want to point out this section of our documentation. If you have a target you're interested in supporting we'd love to discuss more, but #![no_std] won't work "out of the box" today.

In terms of bare-bones requirements Wasmtime at this time requires virtual memory (e.g. an MMU). I've got a branch I haven't upstreamed which distills Wasmtime's base runtime requirements to this C API which would need to be supported by the system.

Wasmtime now supports no_std itself and otherwise having Cranelift support it is tracked at #1158, so I'm going to close this.
