delete breakpoint 对于无用的断点我们可以删除。删除的命令格式为 delete breakpoint 断点编号。info breakpoint命令显示结果中的num列就是编号。删除断点的示例如下: 查看源码 断点设置完后,当程序运行到断点处就会暂停。暂停的时候,我们可以查看断点附近的代码。查看代码的子命令是list,缩写形式为l。 指定行号查看代码...

How can we differentiate unrolled peeled addresses from the rest of the addresses matching the same line so that we can set a breakpoint to them? My understanding is that we would need to create different DIEs for the unrolled parts of the loop and the rolled one. Having a quick look ...
breakpoint 可以根据行号、函数、条件生成断点,下面是相关命令以及对应的作用说明: watchpoint watchpoint是一种特殊类型的断点,类似于正常断点,是要求GDB暂停程序执行的命令。区别在于watchpoint没有驻留某一行源代码中,而是指示GDB每当某个表达式改变了值就暂停执行的命令。

这种断点是当满足一定条件时才会触发,比较适合进行异常排查。设置方式(gdb)break line-or-function if (condition), 如: b src/main.cpp:127 if cnt==10 break main if argc > 1 break 180 if (string == NULL && i < 0) break test.c:34 if (x & y) == 1 ...
