Monitor memory modification between instructions in GDB

Question

Is there any way I can check the memory change before and after si, s or something similar commands?

First came out with the idea of dump memory for diff, but haven't dig in how to do it.

Or maybe there is a better way to do this?

I sometimes set up a display statement to print an expression after every single-step. GDB print statements can have an array operand and various formatting options, so you can get it to print e.g. 20 bytes as hex starting at some address. — Peter Cordes, Commented Jul 6 at 9:22

If you have a small set of memory locations you want to observe, use watchpoints.
