@elmcdonough , let me rephrase this (should've been clearer before, sorry):

Where's the logic that makes sure that `-Wextra` (and other flags that you
redefine here) is reported as unused? That's not clear from this definition:
multiclass FlangIgnoredDiagOpt<string name> {
def unsupported_warning_w#NAME : Flag<["-", "--"], "W"#name>,
Group<flang_ignored_w_Group>;
}
In particular, I don't see anything that would check whether a particular
option is in this group: `flang_ignored_w_Group`.
