The annotated source editor lets you see the amount of time your program spends on each line of code and in each function.
Your application binary must have debug information and your host system must have the source file for a given function for you to see its execution time data in the editor.
To see execution time data for a function:
In the Execution Time view, find the function of interest in the function table or threads tree, then double-click its row or right-click it and choose Show Source.
The IDE opens the corresponding source file in the annotated source editor:
To view quantitative profiling data, hover the pointer over a colored bar. The resulting tooltip shows
the total number of milliseconds and total percentage of execution time for that code.
For children, the tooltip shows the percentage of time relative to the parent.
