 3 Make DOM Exceptions Errors
 4 https://bugs.webkit.org/show_bug.cgi?id=85078
 5
 6 Reviewed by NOBODY (OOPS!).
 7
 8 WebIDL mandates that exceptions should have Error.prototype on its prototype chain.
 9
 10 For JSC we have access to the Error.prototype (and Array.prototype) from the binding code.
 11
 12 For V8 we set a field in the WrapperTypeInfo and when the constructor function is created we
 13 set the prototype as needed.
 14
 15 This patch also adds support for [ArrayClass] since that code is almost identical. It does not
 16 however use [ArrayClass] in any places yet.

 3 Make DOM Exceptions Errors
 4 https://bugs.webkit.org/show_bug.cgi?id=85078
 5
 6 Reviewed by NOBODY (OOPS!).
 7
 8 WebIDL mandates that exceptions should have Error.prototype on its prototype chain.
 9
 10 For JSC we have access to the Error.prototype (and Array.prototype) from the binding code.
 11
 12 For V8 we set a field in the WrapperTypeInfo and when the constructor function is created we
 13 set the prototype as needed.
 14
 15 This patch also adds support for [ArrayClass] since that code is almost identical. It does not
 16 however use [ArrayClass] in any places yet.
