SPEC 2000 results on PowerPC

[Mark Mitchell]

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.
