When profile instrumentation, use or test coverage shall be performed.

void gimple_gen_average_profiler ( )

Output instructions as GIMPLE trees to increment the average histogram
   counter.  VALUE is the expression whose value is profiled.  TAG is the
   tag of the section for counters, BASE is offset of the counter position.

Output instructions as GIMPLE trees for code to find the most common value
   of a difference between two evaluations of an expression.
   VALUE is the expression whose value is profiled.  TAG is the tag of the
