Hi all,

I am implementing a garbage collection algorithm in Jikes RVM and would
like to know answers for these two questions. It seems bit hard to find the
answers for these questions. It would be great if someone could answer me
these questions.

1. I want to know how to activate the return barriers and let the mutators
know that a activation record is about to be popped from the stack.
2. How can I find if an object is pointed by stack root at the time of
assignment?

Thank you for your response in advance.

Cheers
Hari
