Sorry, this is my mistake (for me all instructions with prefix 0F is mmx 
), but not use sse2 + alu.
CPU processing, as well know, that instruction in parallel, where eg. destination operand first is not the source of one of the following.
If use mmx, sse, ... alu bluk "not work" This is optimizing pipeline...
IMHO this is one way for optimalization
