Uh, sometimes you don’t know what’s in the mind of intel guys.

They state in their documentation that the movntq-op (taken over from MMXExt) has to take place on 16-byte aligned memory. What??? Either it’s a copy & paste error, it’s probably suppose to mean 8-byte aligned memory, or you got a command which can’t be executed.

Besides, no op on MMX / 3DNow need alignment, so I think it’s even entirely wong … either way. Nice work intel.
