[PATCH] D49085: [Sema] Emit a diagnostic for an invalid dependent function template specialization

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

This is the right basic approach.  I think it would be better if the diagnostic text was more like `err_function_template_spec_no_match`, maybe "no candidate function template was found for dependent friend function template specialization".  And it would be good to emit notes on any declarations we found but discarded.
