inframe.java

编译原理大作业---tiger编译器 包括semant,translate,mipsframe,regalloc等所有phase 懂的人自会知道

package Mips;

public class InFrame extends Frame.Access {
   private int offset;
   public InFrame(int o) { offset = o; }
   public int getOffset() { return offset; }

   // vedi pagina 163 "Modern Compiler Implementation in Java" (A.W.Appel)
   public Tree.Exp exp(Tree.Exp framep) {
      return new Tree.MEM(new Tree.BINOP(Tree.BINOP.PLUS, framep, new Tree.CONST(offset)));
   }
}
