For AMD64 (including EM64T) you get more registers when putting the CPU in 64-bit mode. A *lot* more registers. That really matters on an architecture where you historically had clost to zero general purpose registers. This is unlike UltraSPARC, where your point is pretty much correct. -- / jakob _______________________________________________ Beowulf mailing list, [EMAIL PROTECTED] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
