-//===- LoopExtractor.cpp - Extract each loop into a new function ----------===//
-//
-// A pass wrapper around the ExtractLoop() scalar transformation to extract each
-// top-level loop into its own new function. If the loop is the ONLY loop in a
-// given function, it is not touched. This is a pass most useful for debugging
-// via bugpoint.
