Points-to analysis computes an abstract model of the memory that is used to answer the following query: What can a pointer variable point-to. i.e., what can its value be when dereferenced during program execution? 
Pointer analysis is a fundamental static program analysis, with a rich literature and wide applications. The goal of pointer analysis is to compute an approximation of the set of program objects that a pointer variable or expression can refer to.
