[PATCH] D109359: [TableGen] Optionally emit a warning for unused template args

[Paul C. Anagnostopoulos via Phabricator via llvm-commits]

Paul-C-Anagnostopoulos added a comment.

(I've been scarce due to summer holidays and, sadly, real work.)

This is a great feature. Do we also need to add an 'unused' declaration that acknowledges the non-use of a template argument and suppresses the warning? Are there legitimate cases where an argument is passed but not used?

I think the test should include a couple of cases where the argument is used, to be sure that no warning is produced.
