Not only a whole loop of two instructions in one cylce: two loops of two instructions in one cycle. Which is still pretty impressive.... :-) Or am I mis-interpreting the bogomips definition? It is the number loops per second right?
My pentium runs this (gcc 2.7.2 compiled) loop at one per two (120MHz) clocks. -> bogo==60. This is not the "official bogomips loop", so my normal bogomips rating is 48.
