Re: [rvm-research] Researching the Jikes RVM

Hi,
I have merged the previous effort on Compressor [1] to the current trunk
locally, and have attached the mercurial diff file herewith
(compressor.diff). There were changes to the trunk after this compressor
implementation, which required some changes in the code of compressor to
make it build. I hope the attached patch will help anyone who would like to
try the compressor implementation quickly, by applying the diff to the
current trunk. I didn't use the diffs uploaded to the Google Site (GSoC),
as further implementation beyond the GSoC timeline has been carried out on
[1]. However, I cross-checked with the diff files to confirm the files.

On a related note, I have figured out the SPECjvm2008, dacapo, and
SPECjbb2005 test cases. I am working further on this [2].

Thank you.
