//===- llvm/Assembly/PrintModulePass.h - Printing Pass -----------*- C++ -*--=//
//
// This file defines two passes to print out a module.  The PrintModulePass pass
// simply prints out the entire module when it is executed.  The
// PrintFunctionPass class is designed to be pipelined with other
// FunctionPass's, and prints out the functions of the class as they are
// processed.
