Yes, the in kernel gcov code -- which already has large parts of the gcov interface, but unfortunately for gcc 3 needs to be updated. This needs to be done inside the kernel tree though. I did some work on this to update, but my efforts fell a bit short. The resulting kernel was actually larger because I was missing some information. My variant didn't need the TLS changes because I just used atomic counters. I also ran into some problems with gcc when the information was not missing some TUs due to the way the information is collected. -Andi -- a...@linux.intel.com -- Speaking for myself only.
