[cfe-dev] How to add a -W flag?

[Thompson, John]

I'm adding a warning to the end of the "Modules Issues" category in DiagnosticSemaKinds.td:

def warn_need_module_import : Warning<
  "Use of identifier '%0' requires import/inclusion of the module '%1'">;

This makes test/Misc/warning-flags.c fail.

A comment in that test file says:

    If you add a new warning without a flag, this test will fail.  To fix
    this test, simply add a warning group to that warning.

I don't know what that means.  How do I add a warning group to the warning?

Thanks.

-John
