  • (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
