8.1.1 Calling Tree (C)

The calling tree is listed after all functions have been compiled. Each function's calling tree information consists of the functions it calls, at what loop nest level the calls are within that function, the total loop nest depth of the calls in that function (including the nesting level of calls to the unit itself), and the routines where that function itself is called.

When the calling tree is selected, a table of the variables used in each function is printed after that function is processed.

For example, the following table appears after the main function:

 CROSS REFERENCE TABLE
