Some benchmarks comparing gcc-3.4.3 and 4.0.0 on PowerPC G5

[Bradley Lucier]

I've put some benchmark results comparing compile and run times for C 
code generated by the Gambit-C Scheme->C compiler at

http://www.math.purdue.edu/~lucier/GNATS/GNATS-18/results.html

There are a fair number of tests where the compile times for 4.0.0 are 
 > 1.5 times the corresponding compile times for 3.4.3.  (Both were 
built without checking.)  The run-time comparisons are more difficult 
to interpret; these tests were run as much to compare -mcpu and -mtune 
options on G5 as to compare compiler performance.

The rest of the directory has the raw data, but I'm not sure it will 
tell you much more than the table.
