8.7.1. Showing system and uncalled functions

You can use contextual menu items to show or hide the system and the uncalled functions. These are only available if you right-click on an area outside of the function rectangles.

The ARM Profiler classifies all functions that begin with either an underscore or 'std::' as system functions, and hides them by default. You can, however, show them by choosing the Show System Functions drop-down menu option. All orphaned functions that are no longer connected to the tree when the system functions are hidden are shown as unconnected boxes at the bottom of the call graph. If this option is active, the contextual menu option changes to Hide System Functions.

The Show Uncalled Functions drop-down menu option works in much the same way as the Show/Hide System Functions option. Select Show Uncalled Functions and all of the functions contained in your code that were not called during the captured execution appears as disconnected boxes in the bottom of the hierarchy.
