> Why do we put callFrameRegister to the stack location of 1 + OBJECT_OFFSETOF(struct JITStackFrame, callFrame) / sizeof (void*)?

We need "1 +" because the return address has been pushed onto the stack by call.

In the old implementation, we would pop the return address off the stack before this code ran.
