Hi all,

These are the per-worker preserved mark stack changes for ParallelGC:

http://cr.openjdk.java.net/~tonyp/8146991/webrev.0/

They are similar to the ParNew changes and rely on some classes I introduced then.

Quick question on this: I moved:

log_trace(gc, ergo)("Restoring " SIZE_FORMAT " marks", total_size());

to the shared code so that the message is logged irrespective of GC (for example, I don’t think we were logging this for ParNew or DefNew). Is “ergo” the right category here though?

Tony
