> do this? That is, I don't see the need for a new option. That would be really odd behavior. An yes/no option whose default is controlled by other object files' command line. And -pg would be for all files in LTO, and no-pg only for that file, so not be symmetric. I think an explicit different option has far cleaner semantics for now (at least until the LTO option mess can be properly cleaned up) -Andi
