There are quite a few things that have their own JIT / code generator instead of using the gcc or llvm infrastructure that has worked for years. New ISAs is always the downside of doing your own code generation. Dotnet doesn't yet have a RISC-V JIT. Samsung are currently doing that. A couple of months ago they had it to the point of a command line Hello World working, but there's still probably a 1-year project for a team to finish everything to production quality. There was a message from the maintainer this week that Luajit is getting close to being usable. Java JVM has worked for a long time but without JIT. I think that is also being worked on but I'm not sure the status. There was a blog post this week with the status of Box64 on RISC-V with some benchmark results. It seems to be basically fairly complete but not yet polished.
