--- Comment #14 from Patrik Huber <patrikhuber at gmail dot com> --- It even seems a few percent slower after the FDO stuff. But the ` -fprofile-use` is a bit weird. If there is no .gcda file, it doesn't complain. If you give it a file that doesn't exist (e.g. -fprofile-use=foo), then it doesn't complain either. So how can I check whether it really ran the FDO?
