//===- llvm/Analysis/ValueNumbering.h - Value #'ing Interface ---*- C++ -*-===//
//
// This file defines the abstract ValueNumbering interface, which is used as the
// common interface used by all clients of value numbering information, and
// implemented by all value numbering implementations.
//
// Implementations of this interface must implement the various virtual methods,
// which automatically provides functionality for the entire suite of client
// APIs.
