Subject Re: [DRLVM][GC] ( Updated:HARMONY-1428) a submission of a mark-compaction GC
Date Thu, 21 Sep 2006 00:28:30 GMT
Weldon, the gc.xml needs a minor change to play with the mark-compaction GC:

             <fileset dir="${src}/gc/src">
                 <select os="win">
-                 <include name="*.cpp" />
+                <include name="mark_compaction/*.cpp" />
                 </select>


Thanks,
xiaofeng
