How to setup GDB to debug assembly?

In the ~/.bash_aliases put this:

#!/bin/bash
alias gdb_asm="gdb -x ~/pathToRepository/AKSO/config/.gdbasm"

If the alias gdb_asm is still unrecognized, reboot or run:

foo@AKSO:~$ source ~/.bash_aliases

How to use GDB to debug assembly?

Run:

foo@AKSO:~$ gdb_asm path/executable

The GDB window should pop out.

Here are the most useful GDB commands:

• b label - puts a breakpoint at the beginning of the given label
• b - puts a breakpoint at the current line
• b N - puts a breakpoint at line N
• d N - deletes breakpoint number N
• info break - lists breakpoints
• r - runs the program until a breakpoint or error
• r params - runs the program with given parameters
• c - continues running the program until the next breakpoint or error
• s - runs the next line of the program
• s N - Runs the next N lines of the program
• q - quits GDB
