nx.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 Translate;

class Nx extends Exp {
   Tree.Stm stm;
   Nx(Tree.Stm s) { stm = s; }

   public Tree.Exp unEx() { return new Tree.ESEQ(stm, new Tree.CONST(-1)); }
   public Tree.Stm unNx() { return stm; }
   public Tree.Stm unCx(Temp.Label t, Temp.Label f) { return null; }
}
