[PATCH] D75574: RFC: Implement objc_direct_protocol attribute to remove protocol metadata

[John McCall via Phabricator via cfe-commits]

One thing that's come up so far: you generally need to be looking through non-runtime protocols, not ignoring them.  This matters when non-runtime protocols inherit from ordinary protocols.  It may be useful to provide a generic function that walks an array of protocols and calls a callback with the unique ordinary protocols it implies.

You should also implement this for non-Apple runtimes, which should be straightforward with that generic function; it's just a matter of testing it.  CC'ing David Chisnall.
