[Mono-dev] field pointer and garbage collection

[Alex Rønne Petersen]

To know if an arbitrary pointer is a GC'd pointer, conceptually you need to ask:

1. sgen_ptr_in_nursery (ptr) ?
2. major_collector.is_valid_object (ptr) ?
3. sgen_ptr_is_in_los (ptr, &base) ?

If all of these are false, you know it's just some random pointer you
don't care about.
