-//===-- CodeGen/MInstBuilder.h - Simplify creation of MInstcn's -*- C++ -*-===//
-//
-// This file exposes a function named BuildMInst that is useful for dramatically
-// simplifying how MInstruction's are created.  Instead of using code like this:
-//
-//   M = new MInstruction(BB, X86::ADDrr32, DestReg);
-//   M->addOperand(Arg0Reg, MOperand::Register);
-//   M->addOperand(Arg1Reg, MOperand::Register);
-//
-// we can now use code like this:
-//
-//   M = BuildMInst(BB, X86::ADDrr8, DestReg).addReg(Arg0Reg).addReg(Arg1Reg);
-//
