But, in that case, lldb (or at least explicit object arguments) would not work with gdb tuning, right? (I assume you're doing this because you need that in lldb). We could say that you need to use -glldb to get these (it wouldn't be the first feature to require it, though it may be the most visible, once people start using these), but it is a bit of an odd choice to make given that gcc (which tunes for gdb "by default") does emit them and maybe gdb also depends on them.
