![](images/i.jpg) *Whenever possible, try to use the 486's 1-cycle instructions, including **MOV, ADD, SUB, CMP, ADC, SBB, XOR, AND, OR, TEST, LEA**, and **PUSH reg** and **POP reg**. These instructions have an added benefit in that it's often possible to rearrange them for maximum pipeline efficiency, as is the case with Terje's optimization described earlier in this chapter.*
