Hi all, I've known that first field in a heap object is map. In the end of JSObject::AddFastProperty, a new map will be set, see:
map()->set_instance_descriptors(old_descriptors); new_map->set_instance_descriptors(DescriptorArray::cast (new_descriptors)); set_map(new_map); but, I want to know, how about the old map? GC will collect the old map or it is stored in some place? --~--~---------~--~----~------------~-------~--~----~ v8-users mailing list [email protected] http://groups.google.com/group/v8-users -~----------~----~----~----~------~----~------~--~---
