Yeah, thanks @peterwaller-arm .  I would need to build bolt with riscv support one day :) I probably fixed it, would check it now. But anyway I'm not ready to submit without one of meta team members approve - I'm pretty sure some of their internal test would fail and it probably needs some kind of test which I don't currently have.
