Taking Linux commit 0538421343 ("gcov: support GCC 7.1") as reference, enable gcc 7 support requiring __gcov_exit() and having 9 counters. Signed-off-by: Jan Beulich <jbeulich@suse.com> --- Considering that gcc 7 has been out for a while, I think we shouldn't ship 4.10 with not even building gcov when using that compiler.
