如果你在没有 调试符号(debugging sysbols) 的情况下进行编译(LCTT 译注:即在使用gcc编译程序时没有写-g选项),然后在bar上设置一个断点,然后尝试在这个函数内使用step来单步执行语句。GDB 会给出一个 没有行号信息(no line number information) 的错误信息。 gcc exmp.c -o exmp gdb ./exmp (gdb) b b...

GDB 反向调试(Reverse Debugging) 这个挺有意思 http://blog.csdn.net/CherylNatsu/article/details/6436570 使用调试器时最常用的功能就是step, next, continue,这几个调试命令都是“往下执行”的,但是很多时候会有这种需求:你在调试的过程中多跳过了几步而错过中间过程,这时候不得不重头调试一遍,非常麻烦。而GDB...

In this chapter, we will introduce you to debugging an assembly program. Debugging is an important skill, because with a debugger you can investigate the content of registers and memory in hexadecimal, binary, or decimal representation. You already know from the previous chapter that the CPU is...
