The purpose of Atlas is precisely to provide the best computing performance. The code tries over and over dozens of different assembly snippets, plays with cache lines, prefetch lengths, inner loops and so on to achieve maximum power. It would not only be a waste, but even an insult against Atlas philosophy not to allow it to be compiled with the most efficient optimizations.
