（转载）如何用gdb进行汇编级的调试

（转载）http://blog.csdn.net/haiyan0106/article/details/1627007

     我的方法是编译成汇编文件后(gcc -S) ，然后用as编译成.o文件，最后再生成执行文件。
给你一个我的调试过程。

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

void test(void)
{
    int number = 10;
    printf("The number: %d\n", number);
}

int main(int argc, char* argv[])
{
    test();

    return 0;
}

（1）生成.s文件

（2）生成.o文件

（3）生成可执行文件
