[PATCH] D32576: [Modules] Improve diagnostics for incomplete umbrella

[Bruno Cardoso Lopes via Phabricator via cfe-commits]

bruno created this revision.

One of the -Wincomplete-umbrella warnings diagnoses when a header is present in the directory but it's not present in the umbrella header. Currently, this warning only happens on top level modules; any submodule using an umbrella header does not get this warning. Fix that by also considering the submodules.
