Now, I'd like to use gdb for this, because I'd like to debug Python bindings that may come as a part of a shared object (.so) library - hence, I'd ideally place a breakpoint on a Python code line, and then "step into" the C part of the shared object... (Note that Debuggi...
From this point on, all the commands and output in GDB will be logged into the specified file.3. Perform the desired actions, such as running the program, setting breakpoints, or stepping through the code.4. When you're done, you can disable the logging using the `set logging off` comm...
The “step”, “next”, and “finish” commands are utilized to step into, step over, and step out with GDB. These GDB commands allow users to identify and fix running program bugs quickly. Remember here that there is a need to set a breakpoint to step through the code, i.e., the...
一条程序代码有可能由数条机器指令完成,stepi可以单步执行机器指令。It is often useful to do ‘display/i $pc’ when stepping by machine instructions. This makes gdb automatically display the next instruction to be executed, each time your program stops. An argument is a repeat count, as in step...

I can step through each by running c (short for continue). That will be ok if it's only called a few times, but if it's called a few thousand times I'll want a different approach. (I'll get back to this in section 15.) 10. Reverse Stepping gdb has a great feature called ...

Manually single-stepping through a program is a slow and tedious process. Therefore 'autostep' aides the user by allowing them to specify sections of code where they suspect an exception could occur. These sections are automatically single-stepped through when the program is running, and any exce...
I can set a breakpoint on doupdate+289, then single-step through each instruction to see how the registers are set and change. First, I need to launch gdb so that we're executing the program live: #gdb `which python`GNU gdb (Ubuntu 7.11.1-0ubuntu1~16.04) 7.11.1Copyright (C) 2016...
