 // This file implements the CloneTrace interface, which is used 
 // when writing runtime optimizations. It takes a vector of basic blocks
-// removes internal phi nodes, clones the basic blocks, and returns the new
-// vector of basic blocks.
+// clones the basic blocks, removes internal phi nodes, adds it to the
