10 # Here we reconstruct the following call trace:
16 # But we find that we're missing an exit record for f2() because it's
17 # tail-called f3(). We make sure that if we see a trace like this that we can
18 # deduce tail calls, and account the time (potentially wrongly) to f2() when
19 # f1() exits. That is because we don't go back to f3()'s entry record to
20 # properly do the math on the timing of f2().
22 # Note that by default, tail/sibling call deduction is disabled, and is enabled
23 # with a flag "-d" or "-deduce-sibling-calls".
