I would love to see the details for this. SpiderMonkey had an attempted wasm32 JIT backend, but it was never finished.

edit: Apparently it also has some sort of WebAssembly interpreter backend too, which SpiderMonkey doesn't have.

+1 from me, as I'm the author of the wasm32 JIT backend. I guess the direction is wrong, it should be JS JIT -> WASM, right? or maybe I don't understand the scheme.
