Mikhail, Wonderful :-) Yes, we are still missing some hoisting opportunities, I saw that in VTune( the old scores I ran are also with JET since the jitrino WB was no yet in svn and I was lazy ). We shoule be able to match RI on allocation rate, we use Appel's algorithm for the allocation of young objects, so our algo is great. We can tune nursery size to some extent I think.
But, better codegen is the key :-) Rana On 10/31/06, Mikhail Fursov <[EMAIL PROTECTED]> wrote:
Rana, With a helper inlined we have significantly better results in your synthetic test. I think we can outperform SUN here if we add some very primitive loop optimizations into the JIT for TLS. I mean moving hythread_self out of the loop as it's already done for BBP. ps. Well, the list of TODO tasks for JIT is growing with a jet speed..
