Hi,

does anyone know a way to compare execution times of programs in the GDB
ARM simulator? Is there something like a cycle counter that I can access
from GDB or from the simulated code?

I found a solution here, about 5 minutes after I had finished writing my
own:

My patch:

Example:
(gdb) sim cycles
S: 636
N: 420
I: 75
C: 0
F: 0
total: 1131
