/// 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.
