//===- 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
// PrintMethodPass class is designed to be pipelined with other MethodPass's,
// and prints out the methods of the class as they are processed.
