I've now got SPEC 2000 results for PowerPC.
I'm using a G5 and ran with "-O2 -mcpu=970". My goal is not to
demonstrate how fast this machine is, but rather to compare the current
mainline with the last release.
The current mainline is, I would say, somewhat better than 3.4.1.
Three tests (176.gcc,187.facerec,189.lucas) work with 3.5, but did not
run at all with 3.4.1, so that is clearly an improvement. Two tests
(186.crafty and 200.sixtrack) that did work with 3.4.1 no longer work
with 3.5 -- that is clearly a degradation. Most of the results are
within 5% of the 3.4.1 results (nine better, six worse). The outliers
are 252.eon (15% improved), 168.wupwise (10% degraded), 177.mesa (7%
improved), and 301.apsi (15% improved).
My current plan is to look into fixing the tests that do not work at
all, and then see what's going on with 168.wupwise.
