Hi, all
This patch results a performance increase of 4% for SPECfp2000 and 13% for NAS
benchmark suite on
Itanium-2 system, respectively. More performance increase is hopeful by further
tuning the
parameters and improving the prefetch algorithm at tree level.
Hi Canqun,
It's great news that you continued to work on prefetching tuning for
ia64! Do you plan to port your other changes for the old RTL
prefetching to the tree level?

I suggest to remove this comment as it has become outdated with your
patch. Instead you might say how did you choose this particular value
(and PREFETCH_BLOCK too). Just my 2c.
