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.
I should note that 176.gcc has a known aliasing problem in its code
which is most
like what is causing it to miscompare and also the extended lvalue
issue.
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.
I should also note that wupwise is fortran and I can tell you I get
about the same
score with gfortran than I get NAG F95 with gcc 3.5.0.
