Fragmentation of address space & dealing with large blocks... And it's not really a 4GB limit, since there has to be a big chunk (likely 1GB) of address space reserved for the kernel. Of course there's a vast variety of apps for which this does not matter at all. But 64-bit makes available some really powerful techniques that are impractical otherwise. Also, wouldn't it be nice if tech writers knew anything about their subject? I got $20 right here that sez the A7 has more than 2 general-purpose registers--anybody want to take that bet ;-) (Maybe somebody doesn't know the difference between a register and a core???) -- Scott Ribe scott_r...@elevated-dev.com http://www.elevated-dev.com/ (303) 722-0567 voice _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
