gdb - 在 GDB 中，如何从用户定义的命令运行内置命令

Question

使用 gdb，我需要在继续之前和中断之后立即运行额外的命令。我想我应该像这样创建一个用户定义的命令:

define continue
    pre_continue
    continue
    post_continue
end

这当然会在无底的递归坑中失败。有没有办法绕过用户定义的命令直接调用内置命令？

顺便说一句:我需要将命令命名为 continue，以便我使用的 gdb 前端能够调用我的用户定义函数。

User-defined Command Hooks是您正在寻找的:

You may define hooks, which are a special kind of user-defined command. Whenever you run the command foo', if the user-defined
commandhook-foo' exists, it is executed (with no arguments) before that command.

A hook may also be defined which is run after the command you executed. Whenever you run the command foo', if the user-defined
commandhookpost-foo' exists, it is executed (with no arguments) after that command. Post-execution hooks may exist simultaneously with pre-execution hooks, for the same command.

此解决方案应该适合您:

define hook-continue
pre_continue
end

define hookpost-continue
post_continue
end
