Please output it as

PERF: %f <arbitrary unique string that explains it>

Analysis tools can then key up on these lines.  There should be one 
line per number, and the number of such lines should be stable, and the 
unique text should be stable.
The entire performance testsuite will follow this one standard, compile 
time, generated code quality, size of generated code...  Bigger == 
worse.  units are arbitrary, but can be things like, seconds, bytes, 
clock ticks, load stalls, cache misses...

Thanks.
