在GDB中执行行

Question

I can execute up to a specific line in GDB by placing a breakpoint there and then pressing c to continue execution.

b <line_number> ; insert breakpoint
c ; run up to the breakpoint
del <breakpoint_number> ; remove breakpoint

Is there a command to run up to a specific line number that will avoid having to run the above sequence of commands?

Answer 1

“ until”命令更加容易，它会自动生成一个临时断点，并一直持续到其位置为止。

Answer 2

You can use temporary breakpoint instead of regular breakpoint. This will eliminate step 3 in your command sequence:

(gdb) tbreak <line_number>
(gdb) continue

Temporary breakpoint is like regular one except it will be deleted when hit:

(gdb) help tbreak 
Set a temporary breakpoint.
Like "break" except the breakpoint is only temporary,
so it will be deleted when hit.  Equivalent to "break" followed
by using "enable delete" on the breakpoint number.
