Peter Wemm 264c3d8738 Undo my previous commit and do it differently. Break the ffs() etc macros ... into two parts - one to do the bsfl and the other to convert the result (base 0) to ffs()-like (base 1) in inline C. This enables the optimizer to be a lot smarter in certain cases, like where it knows that the argument is non-zero and we want ffs(known non zero arg) - 1. This appears to produce identical code to the old inline when the argument is unknown.		1999-08-19 14:54:40 +00:00
