-// This is a utility pass used for testing the InstructionSimplify analysis.
-// The analysis is applied to every instruction, and if it simplifies then the
-// instruction is replaced by the simplification.  If you are looking for a pass
-// that performs serious instruction folding, use the instcombine pass instead.
+// This file implements the library calls simplifier. It does not implement
+// any pass, but can't be used by other passes to do simplifications.
