Hi Mike,

Hmm, OK, but how is this single stepping communicated to the target simulator ?
As far as I can see the AArch64 simulator does not support single stepping
(unless the host has inserted breakpoint instructions into the simulated instruction
space). I assume that this is a bug in the aarch64 simulator code, but what exactly
is wrong ?
Hmm, I see that some other target simulators implement a sim_resume() function of
their own. Perhaps this is the problem - the aarch64 sim should do the same ?
Cheers
Nick
