[PATCH 1/5] benchtests: Add benchmarks for frexp functions

[Paul Zimmermann]

       Dear Osama,

on my computer I get for frexpf with your data set:

  "frexpf": {
   "workload-random-m20-p20": {
    "duration": 3.19203e+09,
    "iterations": 2.616e+08,
    "reciprocal-throughput": 10.5231,
    "latency": 13.8808,
    "max-throughput": 9.50294e+07,
    "min-throughput": 7.20417e+07
   }
  }

If I use the larger data set from lgammaf_r-inputs, I get:

  "frexpf": {
   "workload-random-m20-p20": {
    "duration": 3.22859e+09,
    "iterations": 2.84e+08,
    "reciprocal-throughput": 9.01051,
    "latency": 13.726,
    "max-throughput": 1.10982e+08,
    "min-throughput": 7.28542e+07
   }
  }

There is a significant difference for the reciprocal-throughput.
Can you reproduce that difference?

Usually I use data sets of 1000 values. I see there are very small files,
for example sqrt-inputs. Is there any recommendation for the size of the
data sets?
