Detailed Description

This file implements a simple N^2 alias analysis accuracy evaluator.

The analysis result is a set of statistics of how many times the AA infrastructure provides each kind of alias result and mod/ref result when queried with all pairs of pointers in the function.

It can be used to evaluate a change in an alias analysis implementation, algorithm, or the AA pipeline infrastructure itself. It acts like a stable and easily tested consumer of all AA information exposed.

This is inspired and adapted from code by: Naveen Neelakantam, Francesco Spadini, and Wojciech Stryjewski.
