请教：调试的时候能把能退回上一步

[cao30332]

有时候调试的时候监视一个变量，想退回上一语句或者退回上一个断点，不知道有没有办法，特此请教。

不可以的，重新调试，再运行到你鼠标处。

你太让人失望了。

指令都执行了，退不了。

[arong1234]

有特殊的工具可以的，微软似乎有内部工具可以做到，也有其他团体研究这个可以回退的工具，不过这种工具似乎外面不是很多

[yzx714]

我怕难，至少GDB目前没有这个功能

vs2008调试的时候左边的黄色箭头能往回拉，但是有提示可能出错。

说说你的好办法？
cdb和gdb我都不知道怎么退回上一个断点，还请指教下。

执行代码时居然不可以退回去。。。

有时候挺麻烦的 数据量大的话还得一个个敲键盘输入。

zeta debugger里倒是有一个step back
但是这个独立调试器我死活都玩不来，附带的帮助文档也很有限

[do_fork]

(gdb) help  bookmark 
Set a bookmark in the program's execution history.
A bookmark represents a point in the execution history 
that can be returned to at a later point in the debug session.



(gdb) apropos bookmark
bookmark -- Set a bookmark in the program's execution history
delete bookmark -- Delete a bookmark from the bookmark list
goto-bookmark -- Go to an earlier-bookmarked point in the program's execution history
info bookmarks -- Status of user-settable bookmarks

[do_fork]

这个也可以

(gdb) apropos reverse
rc -- Continue program being debugged but run it in reverse
reverse-continue -- Continue program being debugged but run it in reverse
reverse-finish -- Execute backward until just before selected stack frame is called
reverse-next -- Step program backward
reverse-nexti -- Step backward one instruction
reverse-search -- Search backward for regular expression (see regex(3)) from last line listed
reverse-step -- Step program backward until it reaches the beginning of another source line
reverse-stepi -- Step backward exactly one instruction
rn -- Step program backward
set exec-direction -- Set direction of execution
set remote reverse-continue-packet -- Set use of remote protocol `bc' (reverse-continue) packet
set remote reverse-step-packet -- Set use of remote protocol `bs' (reverse-step) packet
set tui active-border-mode -- Set the attribute mode to use for the active TUI window border
set tui border-mode -- Set the attribute mode to use for the TUI window borders
show exec-direction -- Show direction of execution (forward/reverse)
show remote reverse-continue-packet -- Show current use of remote protocol `bc' (reverse-continue) packet
show remote reverse-step-packet -- Show current use of remote protocol `bs' (reverse-step) packet
show tui active-border-mode -- Show the attribute mode to use for the active TUI window border
show tui border-mode -- Show the attribute mode to use for the TUI window borders

gdb至少5年前就支持调试执行时的回滚了

英语不行的话真的不可以深入C++了。。。~！

[/Quote]惭愧啊，没认真读过GDB的文档，幸好do_fork指正，不然又误导楼主了…………

学习中。。。。

我是来膜拜 do_fork 的～

看牛牛。

高手，佩服一下

佩服 这才知道gdb可以退回调试
