Detailed Description

Description of a LOAD operation that needs to be guarded.

Heritage maintains a list of CPUI_LOAD ops that reference the stack dynamically. These can potentially alias stack Varnodes, so we maintain what (possibly limited) information we known about the range of stack addresses that can be referenced.
