some profiling numbers

[graydon hoare]

hi,

I've recently done some profiling and analysis of gcc and g++, using the 
oprofile hardware-assisted profiling module in linux 2.5. I collected 
stats on a variety of versions of gcc (some only of historical interest) 
and some different branches and workloads, and characterized some 
aspects of the cache and branch-mispredict penalties in addition to 
cycle hotspots.

the results of the work are posted at
      http://people.redhat.com/graydon/gcc-optimizing/
  and http://people.redhat.com/graydon/g++-report/

any comments or questions are welcome (including instructions and 
hand-holding on how to set up the profiler for your own runs, if you 
want to do more of this stuff).
