Subject [jira] Commented: (HARMONY-5098) Support for uncompressed heap references in gc
Date Fri, 16 Nov 2007 08:14:43 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-5098?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12542992

Pavel Pervov commented on HARMONY-5098:

Compression of forwarding pointer can be acomplished but that imposes additional requrement
on a GC.

The requirement is that an object would be moved no farther than +/- 2GB space of its current

If it is ok for GC, we can keep obj_info compressed. If it's not - we have to uncompress obj_info
and align it on native pointer size boundary.
