RISC-V is not particularly good at using opcode space, unfortunately.
- IshKebab 8mo agoI don't think it's too bad. The compressed extension was arguably a mistake (and shouldn't be in RVA23 IMO), but apart from that there aren't any major blunders. You're probably thinking about how JAL(R) basically always uses x1/x5 (or whatever it is), but I don't think that's a huge deal. About 1/3 of the opcode space is used currently so there's a decent amount of space left.
