> -----------------------------------------------------
>
> Key: HARMONY-1806
> URL: http://issues.apache.org/jira/browse/HARMONY-1806
> Project: Harmony
> Issue Type: New Feature
> Components: DRLVM
> Reporter: Alex Astapchuk
> Assigned To: weldon washburn
> Attachments: Barriers.class, Barriers.java, jet_wb4j.patch
>
>
> Attached is implementation of write barriers in Jitrino.JET for Java-based GC (WB4J).
> The WB4J is off by default.
> Note:
> Current implementation calls org.mmtk.vm.Barriers::performWriteInBarrier() method.
> Attached Barriers.class is the fake implementation of the method.
> Please make sure the class is accessible via the *boot*classpath.
> Presuming the Barriers.class is in ./org/mmtk/vm/ and you're using .jet-only mode,
> the following command line turns WB4J on:
> java -Xbootclasspath/p:. -Xem:jet -Djit.JET.arg.wb4j=true Hello
> This patch depends on HARMONY-1785.
> When both wb4c and wb4j requested, then WB4J has a higher priority.
