Class data sharing  support for DRLVM
-------------------------------------

                 Key: HARMONY-5513
                 URL: https://issues.apache.org/jira/browse/HARMONY-5513
             Project: Harmony
          Issue Type: New Feature
          Components: Contributions
            Reporter: Roman S. Bushmanov


This is a contribution of CDS support code for DRLVM.

That was developed in Sept 2006. I'm am attaching it as an archive containing the files which
were added or modified while implementing the feature. I didn't do any merge with current
drlvm sources. I hope the code will be useful to enable CDS feature in the current drlvm.

The attache code allowed storing of an image of classes into a shared archive and loading
the archive at further  vm startups. The list of classes to be stored was read from an external
file.

A the moment I last tried the code, It was able to run EHWA on windows and "Hello world" on
linux.
Performance gain at startup was ~10% on "Hello world" application and 1-2% on Eclipse startup.
