Can you clarify your concern? If people know what they are doing, they should be able to silence the warning (or promote them to an error). > As soon as the integrated assembler can support debug info, we're going to > rip out this warning, and we don't want to be stuck keeping the -W flags > around for backward compatibility. I don't see that as an issue. We never promise that warnings will stay around forever. Once a warning is deemed not to be useful anymore we should feel free to remove it. > Is there some existing warning group that we could use for this? No, and I don't think that would be the right approach anyway. That seems counter to your concern about putting this warning under a flag in the first place. If you really don't want driver warnings to be under a -W flag, then we should consider adding another diagnostic category to segregate them from other warnings. Once we get all warnings under a -W flag, we'd like to change tablegen to reject warnings that are not in a diagnostic group.
