I can't really comment on the actual PPC code, so this needs to be reviewed by somebody else. Structurally the change looks correct. I have one comment about the C1 CAS barrier code, but it's minor. Thanks & cheers, Roman src/hotspot/cpu/ppc/gc/shenandoah/c1/shenandoahBarrierSetC1_ppc.cpp line 83: > 81: LIRGenerator* gen = access.gen(); > 82: > 83: if (ShenandoahCASBarrier) { I am not sure, but I almost think we should not even end up in the method with -ShenandoahCASBarrier. If anything, -ShenandoahCASBarrier should result in only calling super to emit regular CAS without any barriers. ------------- Marked as reviewed by rkennke (Reviewer).
