//===- llvm/Transforms/IPO.h - Interprocedural Transformations --*- C++ -*-===//
//
// This header file defines prototypes for accessor functions that expose passes
// in the IPO transformations library.
//
//===----------------------------------------------------------------------===//
#ifndef LLVM_TRANSFORMS_IPO_H
#define LLVM_TRANSFORMS_IPO_H
class Pass;
//===----------------------------------------------------------------------===//
// createConstantMergePass - This function returns a new pass that merges
// duplicate global constants together into a single constant that is shared.
// This is useful because some passes (ie TraceValues) insert a lot of string
// constants into the program, regardless of whether or not they duplicate an
// existing string.
//
Pass *createConstantMergePass();
//===----------------------------------------------------------------------===//
// createDeadTypeEliminationPass - Return a new pass that eliminates symbol
// table entries for types that are never used.
//
Pass *createDeadTypeEliminationPass();
//===----------------------------------------------------------------------===//
// FunctionResolvingPass - Go over the functions that are in the module and
// look for functions that have the same name. More often than not, there will
// be things like:
// void "foo"(...)
// void "foo"(int, int)
// because of the way things are declared in C. If this is the case, patch
// things up.
//
// This is an interprocedural pass.
//
Pass *createFunctionResolvingPass();
