-// This file defines the NoFolder class, a helper for IRBuilder.  It provides
-// IRBuilder with a set of methods for creating unfolded constants.  This is
-// useful for learners trying to understand how LLVM IR works, and who don't
-// want details to be hidden by the constant folder.  For general constant
-// creation and folding, use ConstantExpr and the routines in
-// llvm/Analysis/ConstantFolding.h.
-//
-// Note: since it is not actually possible to create unfolded constants, this
-// class returns instructions rather than constants.
