用Java实现的编译器。把源代码编译成SPARC汇编程序

class Program
{
    int add(int a, int b)
    {
        return (a + b);
    }

    int sub(int a, int b)
    {
        return (a - b);
    }

    int sum(int a, int b, int c, int d,
            int e, int f, int g, int h)
    {
        return (a + b + c + d + e + f + g + h);
    }

    void main()
    {
        int a, b, c, d;

        a = 1;
        b = 2;

        c = add(a, b);
        d = sub(c, b);

        if (d == a) {
            callout("printf", "correct\n");
        } else {
            callout("printf", "INCORRECT\n");
        }

        callout("printf", "sum of 1 - 8 is %d (36)\n",
                sum(1,2,3,4,5,6,7,8));
    }
}
