42 * SUMMARY: Make our f.caller property match IE's wrt f.apply and f.call
43 * See http://bugzilla.mozilla.org/show_bug.cgi?id=222029
45 * Below, when gg calls f via |f.call|, we have this call chain:
48 * gg() ---------> Function.prototype.call() ---------> f()
51 * The question this bug addresses is, "What should we say |f.caller| is?"
53 * Before this fix, SpiderMonkey said it was |Function.prototype.call|.
54 * After this fix, SpiderMonkey emulates IE and says |gg| instead.
