Well, what other than a trapping insn might cause the basic block
A CALL_INSN, but you miss my point.
First of all, is it a BB boundary or an EH boundary that matters?
Secondly, you don't have to completely stop scanning: what you have to
do is deal with trapping insn across the boundary. That's the big difference.
