Compile times and run times for benchmarks run with gcc-3_0-branch, 20010212, on 500 MHz Alpha 21264 using gambc40a4, with 20 GVM registers and 8 argument registers.
Run times are in milliseconds, compile times are in seconds. All run times that are no more than 10% higher than the minimum run times are in bold; compile times that are more than twice the minimum compile times are in bold. Other compile options were
-mieee -fPIC -fno-math-errno -mcpu=ev6
