[Qemu-devel] Singlestepping on ARM

I'm trying to trace the execution of an ARM (32 bit) guest, with
qemu-system-arm. v2.1.0
I've enabled the -singlestep and -d exec options.

It seems that some guest instructions are not traced once they have
been traced on the first call, as if the translation blocks were
preventing from tracing all guest instructions - only the PC value for
each cached TB. I might also have misunderstood the issue.

Is there anyway (option or code hack) to force QEMU to trace every
guest instruction on each call ?
