//===- SimplifyCFG.cpp - Code to perform CFG simplification ---------------===//
//
-// SimplifyCFG - This function is used to do simplification of a CFG. For
-// example, it adjusts branches to branches to eliminate the extra hop, it
-// eliminates unreachable basic blocks, and does other "peephole" optimization
-// of the CFG. It returns true if a modification was made, and returns an
-// iterator that designates the first element remaining after the block that
-// was deleted.
-//
-// WARNING: The entry node of a function may not be simplified.
+// Peephole optimize the CFG.
