Covoar already produces gcov files. A previous gsoc student did that. This was a bonus task and we were never 100% confident in the gcov files produced.

I would recommend pulling this thread. Produce the normal gcc coverage files, use covoar to produce gcov files, and then run gcov on the results. Compare to what covoar reports and address discrepancies.
