gdb脚本：在选定的断点处执行命令 [英] gdb scripting: execute commands at selected breakpoint

问题描述

我想预先定义gdb脚本中的一些断点，并在这些断点处调用一些特殊的命令，然后自动继续执行程序。所以，理想情况下，我想要一个如下的gdb脚本：

如果上面的断点达到了：
print var1
call someOtherFunction
continue
done

另外一个不幸的事实是，我不能依靠python接口来使用断点，因为我目前工作的服务器上的gdb版本太旧了！

解决方案

您应该查看命令命令，该命令允许您添加命中gdb命令作为断点。请参阅gdb手册的断点命令列表部分。

例如：

  break someFunction 
命令
打印var1 
结束
  

会在 someFunction 被自动打印，自动打印var1 。

I'd like to predefine some breakpoints in a gdb script and to invoke some special commands at these breakpoints and afterwards to automatically continue the program execution. So, ideally, I'd like to have a gdb script like the following:

b someFunction
...
if breakpoint from above reached do:
  print var1
  call someOtherFunction
  continue
done

Additionally an unfortunate fact is, that I can't rely on the python interface for using breakpoints, as the gdb version at the server I currently work at is too old!

解决方案

You should take a look at the command command, which enables you to add gdb commands as a breakpoint is hit. See the breakpoint command list section of the gdb manual.

For example:

break someFunction
commands
print var1
end

will, when the breakpoint on someFunction is hit, automatically print var1.
