-// This file defines the TargetFolder class, a helper for IRBuilder.
-// It provides IRBuilder with a set of methods for creating constants with
-// target dependent folding, in addition to the same target-independent
-// folding that the ConstantFolder class provides.  For general constant
-// creation and folding, use ConstantExpr and the routines in
-// llvm/Analysis/ConstantFolding.h.
