Artificial Functions

Artificial functions are constructed and put onto the User mode call stacks reflecting events in which a thread was in some state within the OpenMP runtime library.

The following artificial functions are defined; each is followed by a description of its function:

When a thread is in an OpenMP runtime state corresponding to one of those functions, the corresponding function is added as the leaf function on the stack. When a thread’s leaf function is anywhere in the OpenMP runtime, it is replaced by <OMP-overhead> as the leaf function. Otherwise, all PCs from the OpenMP runtime are omitted from the user-mode stack.
