// This file defines pass wrappers around LLVM analyses that don't make sense to
|
|
// be passes. It provides a nice standard pass interface to these classes so
|
|
// that they can be printed out by analyze.
|
|
//
|
|
// These classes are separated out of analyze.cpp so that it is more clear which
|
|
// code is the integral part of the analyze tool, and which part of the code is
|
|
// just making it so more passes are available.
