用Java实现的编译器。把源代码编译成SPARC汇编程序

				class Program				{				    int input;   // zero at start								    int main()				    {				        int result;								        if (input == 0) 					{					   input = 10;					}									if (input == 1)					{					   return 1;					}									if (input == 2)					{					   return 1;					}								        input = input-1;				        result = main();								        input = input+1;					input = input-2;					result = result + main(); 					input = input+2;								       					if (input == 10)					{					    callout("printf","%d\n",result);					}				        return result;				    }				}
