I'll give it a try, but it is slow process, -flto needs about 35min compile time and 10.5Gb RAM. Can I relink tobjects compiled without -fwhole-program with that option, or do compile time and 'lto'-time options need to match? > Does CP2K also work? ;) I only tried two tests, but these seem fine. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41069
