Hi,

I am trying to get cycle counts for an ARM target with the ARM simulator 
included with gdb-5.1.1 . I think I am supposed to query a register
$cycles, but no such register shows up from "info reg" and 
"p $cycles" returns void.

A google search reveals that this question has come up before, but
showed no resolution. What am I doing wrong?

thanks,
-David Molnar

The $cycles register was only implemented for a small number of 
simulators (z8k and h8300).
