[jira] Commented: (HARMONY-5231) [drlvm][gc_gen] Implementing allocation prefetch and memset in java GC helpers

["Dmitry Pronichkin (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HARMONY-5231?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12548329 ] 

Dmitry Pronichkin commented on HARMONY-5231:
--------------------------------------------

GC_java_helpers.patch
Previous patch was corrected as Ilya suggested. Additional change is ceiling alignment to 64 bytes which gives small boost and allows to use fast and compact memset.

Native_ceiling_alignment.patch
Ceiling alignment should be done in gc_thread.h as well.

Please review these changes.

Thanks,
Dmitry.

> Hi, 
> The attached patch adds allocation prefetch and memset support to GC java helpers.
> The patch introduces alloc_zeroing method to GCHelper to put the first version into SVN. 
> It does not change existing helper while the new one is implemented in optimal way. 
> Only after this old version will be switched.
