I think you guys may be neglecting the issue of the compiler itself.
Does anyone have any idea how good (or bad) the optimized code generated by
our mips-gnu compiler is? If it's not generating good optimized
code, then all single cpu performance results are going to be lousy,
be they AIM7 or running the compiler itself.
