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