> Attached patch is an implementation of write barrier for C/C++ based GCs in Jitrino.OPT. The patch lets OPT to call "gc_requires_barriers()" of GC to determine if it needs to insert the write barrier code into the jitted code, so it doesn't impact current DRLVM/GC at all.  It calls gc_heap_slot_write_ref( ) of GC module.
> To Apply this patch, please enter vm/ directory and patch it. You can pass '-Xem:opt' to EM to use the OPT-only mode. In any other modes, you should be sure to open the JET write barrier for C/C++ based GCs .
> This patch is based on revision 465123.
> Please review this patch and see if it's ready for commission. Thanks. We hope it can be committed to Harmony soon.
