Siddhesh Poyarekar	81f311c2ee	Add benchmark tests for slowpow and slowexp ... Separate benchmarks for the fast and slow implementations of pow and exp since measuring both together doesn't make sense. Adjust the iterations for pow and exp accordingly so that they run long enough for the measurements to be meaningful.	2013-04-02 17:45:45 +05:30
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
