Also, for performance improvements we generally like to have actual
benchmark results. Could you add a powf benchmark, with whatever inputs
you think are suitably representative, to the benchtests suite, in a
separate patch, and then include before-and-after results for that
benchmark, on any one system of your choice, in the submission of the powf
patch? That then provides a basis for assessing any future powf
improvements or reimplementations anyone else comes up with.
