I think it might make sense to special case the JSFunction class, such as we
can get the object prototype name in addition to the JSFunction class.
Interesting idea. What's the exact code for getting the object
prototype name from a JSFunction?
The corresponding JS code would be:
obj.__proto__.constructor
obj.__proto__ maps to JSObject::getProto(cx, obj, &proto)
.constructor maps to JS_GetConstructor(cx, proto)
Then, if this is a JSFunction, then you can extract the
RootedAtom name(cx);
if (constructor->is<JSFunction>())
name = constructor->as<JSFunction>().displayAtom()
Which would be either the name of the function, or it's inferred name.
This way, for the following code:
function Foo() {}
var x = new Foo();
We should be able to display "Foo" in the memory reporter.
