// This file exposes a function named BuildMI, which is useful for dramatically
// simplifying how MachineInstr's are created. Instead of using code like this:
//
-// M = new MachineInstr(X86::ADDrr32);
+// M = new MachineInstr(X86::ADDrr8);
// M->SetMachineOperandVal(0, MachineOperand::MO_VirtualRegister, argVal1);
// M->SetMachineOperandVal(1, MachineOperand::MO_VirtualRegister, argVal2);
