The former is obviously > much more important. > > If it starts to look like a target issue, then feel free to punt it to me. > While I don't know the v850 fp bits, I have retained a fair amount of > generic v850 knowledge over the decades :-) It is my patch pitfall for very unusual v850 insn constraint 'e!r' where e is even general reg and subset of r. I have a patch to fix this and after testing it I'll commit it today or tomorrow.
