>It looks interesting, however. I'm going to try it with Crafty. Truly speaking I doubt in success of this. Although MMX mode allows to use 8 additional 64 bit register, PII has not a lot of operations allowed with these registers. So a lot of operations must be done on standard 32 bit registers. And there is no (for PII) direct command to send data from 64 bit MMX register to 32 register pair. A few commands or memory should be used for this. As result moving data between 32 and 64 bit register will kill all advantage of fast 64 bit operations.
