Hmm, I don't think we want this - it looks too much like a hack to me.
I guess for an easier way to figure out the min/max ranges (do we
handle anti-ranges?) would be to specify a function name the
debug counter would be enabled for. That might also help in your
situation.
What I've usually done is do the bisection via dbg-counter on
a single file, manually link the spec binary and then
do a runcpu w/o recompiling the binary.
