+
+    2017-11-03  Michael Saboff  <msaboff@apple.com>
+
+            The Abstract Interpreter needs to change similar to clobberize() in r224366
+            https://bugs.webkit.org/show_bug.cgi?id=179267
+
+            Reviewed by Saam Barati.
+
+            Add clobberWorld() to HasGenericProperty, HasStructureProperty & GetPropertyEnumerator
+            cases in the abstract interpreter to match what was done for r224366.
