Test coverage

Hello, folks. If this is not the place to ask, I'm sorry. I would like to know how or where I can find the code coverage for php-src to see if there is any uncovered code I might be able to contribute with new tests. Since gcov.php.net doesn't exist anymore, I was not able to find anything related to it anywhere. I even tried generating a coverage report locally with `lcov --capture --directory . --output-file coverage.info after running make test`, but I got no luck with it. Thank you in advance for your help.
