Thanks for the heads-up, however the 0-DAY bot has caught this issue already last night and I would have addressed it earlier on if not for a failure of my Malta board :( which disrupted my verification. > I tried with gcc 8.3.0, 8.4.0, 9.3.0, and 10.3.0. > > Does this need some additional new compile flags ? MIPSr6 doesn't have the original division instruction along with the MD accumulator registers anymore, and consequently GCC cannot fit the constraint requested. We don't need that asm however. Maybe we didn't with GCC 2.95 either, but I suspect there was something to it. Anyway I have just posted a fix. Maciej
