Thanks for your correction, Ben!


I agree with you. :-)

I understand generally reorder instructions to fully utilize pipeline is a good idea. But I want to know in my specific case, why swap step 2 and step 3 is faster? Could you provide more description please?

I should mention that the compiler might also do this re-ordering. Are you familiar with the 'as-if' rule?
