You mean the "?:" operation? trace-cmd and perf can handle it fine.
Just look at the trace event irq_handler_exit:
print fmt: "irq=%d ret=%s", REC->irq, REC->ret ? "handled" : "unhandled"
# trace-cmd record -e irq_handler_exit
# trace-cmd report
<idle>-0 [001] 856960.382767: irq_handler_exit: irq=29
ret=handled
<idle>-0 [001] 856961.745640: irq_handler_exit: irq=29
ret=handled
<idle>-0 [001] 856961.865762: irq_handler_exit: irq=29
ret=handled
