But this isn't true on all processors. It is true on the pentium, but
probably not on the pentium pro/II. On the pentium pro, rep movsl is
highly optimized microcode. It takes over the whole microarchitecture
and utilizes all possible instruction units (that's why you can't run
other instructions in parallell with a 'rep' instruction on a pentium
pro). I haven't checked this, but take Andy Glew's word for it :-).
