If so, and it's not an i-cache effect, then something is wrong with
the tracing subsystem. It's supposed to compile to something like
if (tracing) {
trace_callback();
}
That is exactly what we have with the debug infrastructure, but
the debug stuff is theoretically a bit worse since it tests for
tracing inside the callback.
Oh well, I guess I need to get my hands on one of these boards.
