Hi Danno,
Here is the use of CallICStub to gather feedback for Array() calls. Toon
went
over much of this a while back, and his comments resulted in:
1) Helper zone object used in Call::set_extra_info() to wrap an
AllocationSite.
The idea being that we might gather myriad different types of feedback from
a
call, so just returning an AllocationSite might not be general enough.
2) Some refactoring that introduced Call::global_call() and
Call::known_global_function().
I didn't create ports yet.
Thanks for the look!
