问题描述
我知道我可以使用 jump 将程序计数器设置为特定的行，这样我就可以跳过一行或多行(或再次执行某些行).我可以轻松跳过下一行而无需输入行号吗?
I know I can use jump to set the program counter to a specific line and so I can skip one or more lines (or execute some lines again). Can I easily just skip the next line without having to enter line numbers?
这将非常方便在运行时注释掉"某些内容.
This would be very convenient to "comment out" something at run time.
推荐答案
jump +1
跳到下一行，即跳过当前行.您可能还想将它与 tbreak +1 结合起来，在跳转目标处设置一个临时断点.
jumps to the next line line i.e. skipping the current line. You may also want to combine it with tbreak +1 to set a temporary breakpoint at the jump target.
参见 http://sourceware.org/gdb/current/onlinedocs/gdb/Specify-Location.html 了解使用 gdb 表达位置的更多方式.
See http://sourceware.org/gdb/current/onlinedocs/gdb/Specify-Location.html for more ways of expressing locations with gdb.
注意，没有断点的gdb很可能会继续正常执行而不是跳转.因此，如果跳跃似乎不起作用，请确保在目的地设置断点.
Note that without a breakpoint gdb is likely to continue execution normally instead of jumping. So if jumping doesn't seem to work, make sure you set a breakpoint at the destination.
