-//===- OptimizerDriver.cpp - Allow BugPoint to run passes safely ----------===//

-//===----------------------------------------------------------------------===//
-//
-// This file defines an interface that allows bugpoint to run various passes
-// without the threat of a buggy pass corrupting bugpoint (of course, bugpoint
-// may have its own bugs, but that's another story...).  It achieves this by
-// forking a copy of itself and having the child process do the optimizations.
-// If this client dies, we can always fork a new one.  :)
