Subject: [PATCH] show(IRGS): show all elements on the stack, not just half

Summary:
stackDepth is the thing that indicates total number of elements, spOffset is
just a current cursor that gets updated with every iteration. If we are
iterating until spOffset and decrementing spOffset at the same time, we print
only half of stack items.
