Class CodeGen.InstrDELAYSLOT

java.lang.Object
  harpoon.IR.Assem.Instr
      harpoon.Backend.Sparc.CodeGen.InstrDELAYSLOT

All Implemented Interfaces:

HCodeElement, CFGraphable<Instr,InstrEdge>, UseDefable, Graph.Node<Instr,InstrEdge>

Enclosing class:

CodeGen

public class CodeGen.InstrDELAYSLOT
extends Instr

Sub-class to represent delay-slots. optimize() uses this class information to determine that it should rearrange code to try to eliminate these instructions.
