As the Perf tool only provides periodic samples, the CPU Usage Analyzer
cannot determine the exact time when a function was called or when it
returned. You can, however, see exactly when a sample was taken on the
returned. You can, however, see exactly when a sample was taken in the
second row of each thread. The CPU Usage Analyzer assumes that if the same
function is present in the same place in the call chain in multiple samples
on a row, then this represents a single call to the respective function.
This is, of course, a simplification. Also, there may be other functions
being called between the samples taken, which do not show up in the profile
data. However, statistically, the data is likely to show the functions that
spend the most CPU time most prominently.

If a function without debug information is encountered, further unwinding
of the stack may fail. Unwinding will also fail if a QML or JavaScript
