to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

/// 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.
|
|
