Why do you think it will not work well with LTO? The instrumentation and annotation already happens at the same place which is why the same options are required. They just happen after some inlining and other early optimization to make sure the profiling does not get too slow. -- Pinski -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35544
