|
|
// 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.
