For ``inbounds`` all rules of the ``nusw`` attribute apply. Additionally,
if the ``getelementptr`` has any non-zero indices, the following rules apply:

* The base pointer has an *in bounds* address of an allocated object, which
means that it points into an allocated object, or to its end. Note that the
object does not have to be live anymore; being in-bounds of a deallocated
object is sufficient.
* The base pointer has an *in bounds* address of the allocated object that it
is :ref:`based <pointeraliasing>` on. This means that it points into that
allocated object, or to its end. Note that the object does not have to be
live anymore; being in-bounds of a deallocated object is sufficient.
* During the successive addition of offsets to the address, the resulting
pointer must remain *in bounds* of the allocated object at each step.
