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