Weldon, what is the "user-mode"?
Thanks for asking. Basically I call MMTk's object alloc() routine from java application code instead of from DRLVM JIT runtime helper. I use vmmagic to patch up stuff. The trick is to hide the objects allocated out of MMTk's heap from the underlying GCV4. For more detail, please look at drlvm/trunk/vm/mmtk/*.java files. --
