Inserting profiling function calls
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 and i hope this subject will be interesting enough for you to give me attention. I begin to localize were to insert/add this functionality but more detailed on "a magic how to" insert function calls in the generated code would be very helpful for me. Is there somewhere a guide line to add profiling pass ? Thank you for your help, Patrice ___ Yahoo! Mail réinvente le mail ! Découvrez le nouveau Yahoo!

Re: Inserting profiling function calls
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 function call, like mcount is inserted at the function level for gprof but at the basic block level. A user library linked with the application can then implement this functions. Thank you, Patrice ___ Yahoo! Mail réinvente le mail ! Découvrez le nouveau Yahoo!
