; compare is done on integer unit, but feeds insns which
-; execute on the branch unit. Ready-delay of the compare
-; on the branch unit is large (3-5 cycles). On the iu/fpu
-; it is 1. One drawback is that the compare will also be
-; assigned to the bpu, but this inaccuracy is worth for being
-; able to fill the compare-branch delay, with insns on iu/fpu.
