Adhemerval Zanella	60c414c346	PowerPC: remove branch prediction from rint implementation ... The branch prediction hints is actually hurts performance in this case. The assembly implementation make two assumptions: 1. 'fabs (x) < 2^52' is unlikely and 2. 'x > 0.0' is unlike (if 1. is true). Since it a general floating point function, expected input is not bounded and then it is better to let the hardware handle the branches.	2013-04-01 06:36:51 -05:00
