Like most debuggers, we view things from steps.
-
break _start. This creates a breakpoint at the start of program
-
run
-
layout asm
To view register info, you can type: - info register r0
- layout regs
To continue steps, you can type: stepi
We can also examine inside a register. The values, if it is too big to be contained.
x/[number][display] $[register]
x/ is the examine key
[number] can be any digit like 10
[display] must be in a display for hex, decimal, character,etc. Can be: x,d,c
[register] will be a register like r1, r2, etc.
An example x/ can be: x/10d $r1
