Checks that the DFG CFA does the right things if it proves that a put_by_id is a simple replace when storing to a specialized function property.

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".


Passed some tests silently.

fourthTier: DFG GetById patching shouldn't distinguish between self lists and proto lists https://bugs.webkit.org/show_bug.cgi?id=117377 Source/JavaScriptCore: Reviewed by Geoffrey Garen. Previously if you did self accesses and then wanted to do a prototype access, you'd have a bad time: the prototype accesses would be forced to take slow path because the self list wouldn't allow prototype accesses. Likewise if you did prototype (or chain) accesses and then wanted to do a self access, similar stupidity would ensue. This fixes the stupidity. I believe that this was introduced way back in the days of the old interpreter, where distinguishing between self lists, proto lists, and chain lists was meaningful for interpreter performance: it meant fewer branches to evaluate those lists. Then it got mostly carried over to the old JIT since the old JIT was just initially an optimized version of the old interpreter, and then later it got carried over to the DFG because I didn't know any better at the time. Now I do know better and I'm fixing it. * bytecode/PolymorphicAccessStructureList.h: (JSC::PolymorphicAccessStructureList::PolymorphicStubInfo::set): * bytecode/StructureStubInfo.h: (JSC::StructureStubInfo::initGetByIdSelfList): * dfg/DFGOperations.cpp: * dfg/DFGOperations.h: * dfg/DFGRepatch.cpp: (JSC::DFG::tryCacheGetByID): (JSC::DFG::getPolymorphicStructureList): (DFG): (JSC::DFG::patchJumpToGetByIdStub): (JSC::DFG::tryBuildGetByIDList): (JSC::DFG::dfgBuildGetByIDList): LayoutTests: Reviewed by Geoffrey Garen.
