With the introduction of stack objects, VARKILL information is no longer needed. With stack objects, an object is dead when there are no more static references to it, and the stack scanner can't find any live pointers to it. VARKILL information isn't used to establish live ranges for address-taken variables any more. In effect, the last static reference *is* the VARKILL, and there's an additional dynamic liveness check during stack scanning. Next CL will actually rip out the VARKILL opcodes.
