address. Therefore there is no need to consider the length at runtime. (In effect the address is just a unique identifier which is easy to create, it has no real semantic content beyond that).<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">I see that dependency edges are created between nodes based on the base address (base_addr) of the dependency. However, I don't see the length (len) being taken into consideration to determine node connections.<o:p></o:p></p>
