>                 Key: HARMONY-816
>                 URL: http://issues.apache.org/jira/browse/HARMONY-816
>             Project: Harmony
>          Issue Type: New Feature
>          Components: Contributions
>         Environment: DRLVM+Jitrino
>            Reporter: Alex Astapchuk
>         Attachments: magics.cpp, magics.cpp, magics.cpp, magics.cpp, PlanLocal.java,
test.java, wb4j_jet.diff
> Initial implementation of write barriers for MMTk in Jitrino.JET,
> including support for magics.
> To use the implementation:
> 1. copy wb4j_jet.diff into vm/ and apply 'patch -p0 < wb4j_jet.diff'
> 2. copy magics.cpp into vm/jitrino/src/jet
> 3. compile attached test.java and PlanLocal.java (note: you need 
> org/vmmagic/unboxed or its stubs available)
> By default, the WB code generation is off, to turn it on start VM as
> follows:
> ij -Xem jet: -Xjit jet::wb4j test
> Currently, you will see no visible effect, you can only test it in debugger.
> Note: current implementation only inserts WBs into a method named testWB of class test.
> This is done intentionally to avoid breaking normal execution of bootstrap.
> If you want to change this behavior, then please edit vm/jitrino/src/jet/compiler.cpp
> (look for string test::testWB).
