------- Comment #5 from pthaugen at us dot ibm dot com 2007-08-03 15:30 -------
This patch gives us an additional 2-3% overall on CPU2000, running on Power6.
Facerec was the big winner with about 40% improvement, there were a few
improvements in the 5-10% range and a few degradations in the 1-2% range that
could be attributed to other issues like loop alignment or possibly an issue
with r0 getting assigned to the base reg by renaming which I'm currently
testing a patch for.
