Hey, It's good to hear from you again! We don't have plans for adding a JIT/Wasm backend for RISC-V at this point. Most of SpiderMonkey (except Wasm support) should work without it, it's just slower without JITs. Making sure a --disable-jit build of Firefox works on RISC-V would be a good first step.
We could _potentially_ have a community-maintained JIT/Wasm backend for RISC-V, like our MIPS code, but this would also depend on the impact to other parts of the code base and whether the community is willing to actively maintain it going forward. Adding a JIT backend is a big project. We'd be happy to answer questions and give feedback though. You can also find us in the #spidermonkey room on Matrix [0].
