- Subject: 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
