- Subject: Some benchmarks comparing gcc-3.4.3 and 4.0.0 on PowerPC G5
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.
