There are still lots of x86 machines out there, including the upcoming, dual-core Yonah chip, so providing SIMD versions of the libraries for x86 is worthwhile, IMO. Which libraries have vectorized variants on x86-64? I only saw one for my x86 box... jesse -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
