Hi Qiong,
I tried to apply and to build your patch on Windows.
I checked out the revision required by the patch, built the code but had
some problems to run it: the VM crashed at startup. I'll try to build the
patched version on Linux (as you did) a
I am curious about a bug in my implementation. I instrumented the
profile code using jet. And I referred that it can`t works with
compress and javac of jvm98.
Today I found out that if I only use jet (-Xem jet), both of the
benchmark can run successfully. While I use jet and opt, it will

Also I have a proposal: let's choose SVN revision number as the base and
post only diffs to this revision to JIRA. How do you think, will it work?
Doing this we will minimize the size of the patches?

uld we gain some success in a feature implementation before we get a
commiter's help and separate branch in SVN?

Have you already done any estimation what does it cost? I.e. how many

yes, perfect right.
How do you think, should patterns depend on certain JIT and GC
tightly? I suspect they depend heavily on GC, and not-so-much on
JIT. Though, I should say that JET uses a very cheap register

As for your listed 3, we need to abstract the Data reference trace. And we
won`t recode the data reference trace in all iterations of the loop, we just

for 100, or maybe less. So the trace won`t be too large. And Chilimbi prove

Hi, Sir,
I am afraid, i can`t attach the java application with gmail, maybe
it`s too large??
Its size is 24M, within the 1G of gmail, isn`t it?
Is there other ways i can attach my jar files?
We test the performance of drlvm with the benchmark specjbb2000, and the
score is a little lower than jdk1.5.
But i think the modularization and readability are much better than jdk1.5
