Hi everybody,
Looking at org.mmtk.plan.generational.Gen, I see these constants:
public static final boolean USE_OBJECT_BARRIER_FOR_AASTORE = false; // choose between slot and object barriers
public static final boolean USE_OBJECT_BARRIER_FOR_PUTFIELD = false; // choose between slot and object barriers
I notice that if they are set to true, the applications go faster in general. I was wondering what the tradeoff is, if any, between having them set to true and false.
Also, I'm curious about the tradeoff between USE_DISCONTIGUOUS_NURSERY true and false.
The only place where they are tested is org.mmtk.plan.generational.GenMutator, in the fastPath(...) method.
Is there any place where I can read what the difference is between using slots and object barriers?
Thank you very much.
Cristian.
