New issue 1832 by mikhail.naganov: Explicitly mark weak references in heap
profiler
http://code.google.com/p/v8/issues/detail?id=1832
There are several kinds references that are weak:
- weak persistent handles;
- [FIRST_WEAK_SLOT..GLOBAL_CONTEXT_SLOTS) in Contexts;
- initial_map in SharedFunctionInfo;
- [kNonWeakFieldsEndOffset..kSize) in JSFunctions.
We need to mark corresponding edges in heap snapshots to avoid counting
there references in retaining paths calculation.
Ideally, we should create some kind of annotations that will feed
references weakness information into snapshots generator automatically.
