+
+ ES6: Implement Object.setPrototypeOf
+ https://bugs.webkit.org/show_bug.cgi?id=145202
+
+ Reviewed by Darin Adler.
+
+ * http/tests/security/cross-frame-access-object-setPrototypeOf-expected.txt: Added.
+ * http/tests/security/cross-frame-access-object-setPrototypeOf.html: Added.
+ * http/tests/security/resources/cross-frame-iframe-for-object-setPrototypeOf-test.html: Added.
+ Test covering cross origin restriction behavior.
+
+ * js/Object-getOwnPropertyNames-expected.txt:
+ * js/script-tests/Object-getOwnPropertyNames.js:
+ Updated for the new exposed property.
+
+ * js/cyclic-prototypes-expected.txt:
+ * js/script-tests/cyclic-prototypes.js:
+ Extend this test to include setPrototypeOf cyclic checks.
+ Note that setPrototypeOf can still change the prototype
+ where __proto__ cannot.
+
+ * js/prototypes-expected.txt:
+ * js/script-tests/prototypes.js:
+ Extend this test to cover more types previously overlooked.
+
+ * js/script-tests/setPrototypeOf.js: Added.
+ (debugEval):
+ (getObjectDescriptions.myFunction):
+ (getObjectDescriptions):
+ * js/setPrototypeOf-expected.txt: Added.
+ * js/setPrototypeOf.html: Added.
+ Test coverage for all the different object / prototype combinations.
+ This is modeled after the other browser tests with coverage of a
+ few more basic functionality tests and object types.

+ ES6: Implement Object.setPrototypeOf
+ https://bugs.webkit.org/show_bug.cgi?id=145202
+
+ Reviewed by Darin Adler.
+
+ * runtime/JSGlobalObjectFunctions.h:
+ * runtime/JSGlobalObjectFunctions.cpp:
+ (JSC::globalFuncProtoSetter):
+ (JSC::checkProtoSetterAccessAllowed):
+ Extract a helper to share this code between __proto__ setter and setPrototypeOf.
+
+ * runtime/ObjectConstructor.cpp:
+ (JSC::objectConstructorSetPrototypeOf):
+ Implementation is very similiar to __proto__ setter.
