Compile times and run times for benchmarks run with gcc 3.0.1 and 3.1 on 500 MHz Alpha 21264 using gambc40a7.

Compile and run times are in seconds. All run times that are no more than 5% higher than the minimum run times are in bold; the minimum run times are in green bold. Compile times that are greater than twice the minimum compile times are in red.

Other compile options were

-mieee -fomit-frame-pointer -fno-math-errno -mcpu=ev6 -fno-strict-aliasing -fschedule-insns2
