用Java实现的编译器。把源代码编译成SPARC汇编程序

class Program
{
    int x[1000];
    int y[1000];


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

        // load arrays
        while (i < 1000) {
            x[i] = i;
            y[i] = 0;
            i = i + 1;
        }
        
        i = 998;
        while (i > 0) {
            a = x[i+1];
            b = x[i];
            c = x[i-1];
            
            d = b * 2;
            d = d + a;
            d = d + c;
            
            y[i] = d;
            i = i - 1;
        }
        
        i = 0;
        while (i < 1000) {
            callout("printf", "%d ", y[i]);
            i = i + 1;
        }
        
        callout("printf", "\n");
    }
}
