I am pretty excited about RISC-V. Hoping to see a v8 JavaScript and Node.js port in the future.

That shouldn't be super hard. I don't think there is much assembly in either. And C can be compiled to RISC-V already.

My only experience porting node was to a specialized ARM system a while ago, so ARM support may have been already built in or things may have changed.

edit: as people have commented, there indeed is a fair amount of arch specific stuff for reference the mips directory https://github.com/v8/v8/tree/master/src/mips64

V8 has a JIT, which is always going to require work to port to a new architecture. But the new-ish TurboFan backend is supposed to have the architecture-dependent parts relatively well factored out[1], so it's not as hard as it might be.

v8 is a JIT compiler. It emits instructions for specific architectures. So even if it's not written in assembly, it has some very architecture specific parts in it.
