Description Carl A. Dunham 2003-08-03 19:58:02 UTC
May be helpful for people trying to find optimal CFLAGS so we can really find out if source-based 
distributions have this as an advantage. 
Things it really needs to get to the next level: 
- More "real world" application behavior - disk reads/writes, multimedia, device i/o, graphics, etc 
- multiple runs accumulating stats - right now it runs each combination once, so if a big email comes 
in during a test, the results might be skewed 
- some intelligence about what flags are incompatible/redundant with others 
- ditto for choosing flags not appropriate for the hardware 
On that last point, I didn't have any flag combos that produced un-runnable code, even thought it 
ran through all the -march possiblities (Intel and AMD) that it could think of. I would say this means 
it needs some code that would be helped/broken by architecture/cpu-specific flags.  

Reproducible: Always
