C代码MIPS汇编

#include <stdio.h> 

int sum (int L, int U) { 
    if (L == U) return L; 
else { 
    int lower, upper; 
    int mid = (U+L)/2; 
    lower = sum (L, mid); 
    upper = sum(mid+1, U); 
    return (lower+upper); 
} 
} 
int main(){ 
     int x,y; 
     scanf("%d %d",&x,&y); 
     printf("The result is: %d\n",sum(x,y)); 
}

我认为他希望我们手动将它编译成MIPS。：P – 2011-03-22 12:13:30

使用C编译器，这是他们设计的目的。 – Lindydancer 2011-03-22 12:14:15

我会屈服于讽刺的诱惑和发布此：

这是由GCC交叉编译器我刚刚建立了MIPS-linux的小精灵制作目标，使用以下命令行：

mips-linux-elf-gcc -fomit-frame-pointer -S hello.c

由于您使用的是Windows，你应该谷歌搜索类似mips cross-compiler for windows。

你究竟想做什么？

翻译这个代码在mips汇编....好吧谢谢大家的帮助:-) – manos 2011-03-22 15:35:26

我可以在spim中运行这段代码吗？ – manos 2011-03-22 16:13:30
