However, on x86, the 32->64 bit jump also gives a larger register set and (IIRC) SSE (or SSE2?) on all chips, which allows better code generation for all kinds of things. The i386 architecture is register-starved compared to many other architectures. -- Chris Adams <cmad...@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. -- fedora-devel-list mailing list fedora-devel-list@redhat.com https://www.redhat.com/mailman/listinfo/fedora-devel-list
