------- Comment #23 from Kelemen.Balazs.3 at stud.u-szeged.hu  2008-10-06 04:16 PDT -------
We reimplemented our solution for JavaScriptCore by taking into account your
comments. Now we only inherit classes from AllocBase which are ever allocated
on the heap. Visibility of inheritances are not changed and we did not change
structs.

We present the results of SunSpider on the original and on the modified WebKit
(more precisely, on JSC). As you can see, there is no significant difference
between the two versions.
