I don't think -freorder-blocks-and-partition ever was stable enough to work with profiledbootstrap. From day one, it was fragile and not well covered in regression testing. I hope the verifiers will make life a bit more bearable, and that the fixes from Teresa will allow us to enable -freorder-blocks-and-partition with -fprofile-generate. Has anyone ever investigated the effects of -freorder-blocks-and-partition vs. the function splitting part if flag_partial_inlining (ipa-split.c)? Ciao! Steven
