As has been requested of our submissions in the past, please provide
performance results for AMD and Intel platforms.
We are in the process of reviewing the routine for AMD processors and
this comes at a short notice for us to do detailed measurements across
our processors. We will evaluate the impact of this routine on AMD
hardware before it is checked in. As Ulrich has mentioned in the past,
we should aim towards a blended implementation.
We also ask you review our outstanding submissions.
