Each interpreted method has a frame on the stack; these frames are
interpreted frames. On entry, interpreted methods expect to find
their arguments at the end of their caller's frame. For the very
first call there won't be an interpreted frame preceding, so for
the first call a thing called the call stub creates a special frame
with the arguments at the end; this is the entry frame.
Cheers,
