* Add powf traceWilco Dijkstra2017-06-201-0/+2187
| | | | | | | | Add a workload for powf. This is a reduced trace based on 2.3 billion samples extracted from wrf. The distribution of values, in particular frequency of commonly used operands is the same as in the full trace. * benchtests/powf-inputs: Add reduced trace from wrf.
* Add powf bench testsPaul Clarke2017-06-201-0/+331
Add powf() bench test with input which covers these cases: - positive base to positive exponent - exponent 0 - negative base to even exponent - exponent 1 - exponent -1 - squared - squareroot - 1 to negative exponent - -1 to negative exponent - base 0 - -1 to even exponent - small base - small exponent * benchtests/Makefile (bench-math): Add powf. * benchtests/powf-inputs: New file.
