//===- llvm/Analysis/LoadValueNumbering.h - Value # Load Insts --*- C++ -*-===//
//
// This file defines a value numbering pass that value #'s load instructions.
// To do this, it finds lexically identical load instructions, and uses alias
// analysis to determine which loads are guaranteed to produce the same value.
//
// This pass builds off of another value numbering pass to implement value
// numbering for non-load instructions.  It uses Alias Analysis so that it can
// disambiguate the load instructions.  The more powerful these base analyses
// are, the more powerful the resultant analysis will be.
