In that case, not so surprising that the div1 function loses. Do other
architectures also have decent performance for small-quotient division?
I don't have the full picture, I'm afraid.
I know several ARM cores have great division performance for small
quotients. For x86 I know of cores with horrible performance and ones
(like Haswell and later) with half decent performance. I assume newer
AMD cores got this right.
