ex.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 Ex extends Exp {
   Tree.Exp exp;
   Ex(Tree.Exp e) { exp = e; }

   public Tree.Exp unEx() { return exp;}
   public Tree.Stm unNx() { return new Tree.EXP(exp); }

   // se exp = 0 allora salta a f altrimenti a t
   public Tree.Stm unCx(Temp.Label t, Temp.Label f) {
      return new Tree.CJUMP (Tree.CJUMP.EQ, new Tree.CONST(0), exp, f, t);
   }
}
