Despite its age, gdb remains an amazingly versatile and flexible tool, and mastering it can save you huge amounts of time when trying to debug problems in your code. In this post, I'll share 10 tips and tricks for using GDB to debug most efficiently. I'll be using the Linux kernel f...
set step-mode on 打开step-mode模式,于是,在进行单步跟踪时,程序不会因为没有debug信息而不停住。这个参数有很利于查看机器码。 set step-mod off 关闭step-mode模式。 finish 运行程序,直到当前函数完成返回。并打印函数返回时的堆栈地址和返回值及参数值等信息。 until 或 u 当你厌倦了在一个循环体内单步跟踪...

二:执行程序 要想运行准备调试的程序,可使用run命令,在它后面可以跟随发给该程序的任何参数,包括标准输入和标准输出说明符()和外壳通配符(*、?、[、])在内。 如果你使用不带参数的run命令,gdb就再次使用你给予前一条run命令的参数,这是很有用的。 利用set args命令就可以修改发送给程序的参数,而使用show args ...

Gdb Assembly Informant steps through your assembly code one instruction at a time and diffs register values. - thlorenz/gai
Greg demonstrated this with reverse stepping, so you can imagine following both code and assembly execution at the same time (I'd need a video to demonstrate that here). 14. External: cscope I still want to learn more about back_color_erase, and I could try gdb's search command, but ...
With the debug info package installed, gdb can list the source along with the assembly: (gdb) disas/s Dump of assembler code for function doupdate: /build/ncurses-pKZ1BN/ncurses-6.0+20160213/ncurses/tty/tty_update.c: 759 { 0x00007f0a37aac2e0 <+0>: push %r15 0x00007f0a37aac2e2 <...
