Subject [jira] Updated: (HARMONY-5098) Support for uncompressed heap references in gc
Date Thu, 08 Nov 2007 19:13:50 GMT

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

Rana Dasgupta updated HARMONY-5098:
-----------------------------------

    Attachment: uncompress.patch

Please don't commit, this is work in progress.

This patch builds two gc dll's. gc_gen is for 32 bit and uncompressed refs( built with REFS_USE_UNCOMPRESSED).
gc_gen_compress for compressed refs( built with REFS_USE_COMPRESSED ).  

It simplifies the compile/runtime mode selection logic to COMPRESSED_MODE=compressed|uncompressed.
Default for 64 bit is runtime selection based on heapsize. VM loads correct gc dll accordingly.


gc_supports_compressed_references() returns true/false based on gc dll loaded.
