Andras, The whole point of benchmarks is to judge a processor's performance. That being said, just crippling GCC is not reasonable because processors must be judged in the appropriate context and that includes the current state of the art compiler technology. If you have a new processor I'd benchmark it using the applications you built it for.

Is there a way to make it less clever about the benchmark? Or is there some alteration to the benchmark I can make to not trigger the special behavior in GCC?
