Would you for a start please explain what do you need to do that can't be done using existing arc and value profiling? Sorry, my first mail was not clear about the goal. Objectives are to follow the execution of function and basic block at execution time. To do this, we plan to insert func

Dear All, In order to implement a specific basic block profiling, i have to insert function calls at the end of each basic blocks or/and at the end of each functions. To do this I'd like to add a profiling pass similar to the arc profiling. I'm a beginner in the GCC internal implementation
