[PATCH] D77077: [clang] CodeGen: Make getOrEmitProtocol public for Swift

[Arnold Schwaighofer via Phabricator via cfe-commits]

aschwaighofer added a comment.

> Can you explain the need for the callback? Are you expecting to use this for Swift-declared protocols by synthesizing an ObjC protocol declaration for them? I can see why you'd need a callback in that case.

The objective C protocol references other protocols in its inherited list. Swift has an internal list that keeps track of those protocols references and makes sure to initialized them for the debugger and also makes sure that the underlying protocol structure is emitted. The call back is to keep this list in sync.
