用Java实现的编译器。把源代码编译成SPARC汇编程序

class Program
{
    int array_cst_in_class[4];

    void test(int i, int j)
    {
        callout("printf","test received %d, should be %d\n",i,j);
    }

    int test2()
    {
        return array_cst_in_class[0];
    }

    int test3()
    {
        array_cst_in_class[1] = array_cst_in_class[2];
	return 1;
    }

    void main()
    {
	int i1, i2, i3;

        // first test all the local/stack array stuff

	i1 = 0;
	i2 = 0;
	i3 = 0;

	while(i1 < 4) {
	  array_cst_in_class[i1] = i1;
	  i1 = i1+1;
	}

        i1 = 0;
	while(i1 < 4) {
          callout("printf","%d:%d ",i1,array_cst_in_class[i1]);
          i1 = i1+1;
	}
        callout("printf","\n");

	test(array_cst_in_class[2],2);
	test(array_cst_in_class[i1*4-14],2);

        callout("printf","should be 2: %d\n",
	        array_cst_in_class[array_cst_in_class[2]]);

	array_cst_in_class[0] = array_cst_in_class[1];

        callout("printf","should be 2: %d\n",
	        1+array_cst_in_class[array_cst_in_class[test2()]]);

        callout("printf","should be 2: %d\n",
	        array_cst_in_class[array_cst_in_class[test3()]]);
    }
}
