Subject [jira] Updated: (HARMONY-3063) [drlvm][jit] ArrayCopyRepMove does not work on EM64T
Date Tue, 06 Feb 2007 04:50:05 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-3063?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

George Timoshenko updated HARMONY-3063:
---------------------------------------

    Attachment: arraycopy_rep_move_em64t_enabling.patch

some modification from the patch was not appeared in the svn. Here it is:

 #endif
 
     // prepare counter
-    Type* counterType = typeManager.getInt32Type();
+    Type* counterType = typeManager.getIntPtrType();
     Opnd* counter = irManager.newRegOpnd(counterType,counterRegName);
     copyOpnd(counter,(Opnd*)args[4]);
 

I do not know why I happened. 
So it is clear now why I could not reproduce eclipse 3.1.1 hanging and classlib tests failures.

Alexey, please try again.
