[PATCH] D87395: Sema: add support for `__attribute__((__swift_objc_members__))`

[Dmitri Gribenko via Phabricator via cfe-commits]

gribozavr2 added inline comments.


================
Comment at: clang/include/clang/Basic/AttrDocs.td:3387
+The ``swift_objc_members`` attribute maps to the ``@objcMembers`` Swift
+attribute, which indicates that Swift members of this class, its subclasses, and
+all extensions thereof, will implicitly be exposed back to Objective-C.

Sure, how about this: "This attribute indicates that Swift subclasses and members of Swift extensions of this class will be implicitly marked with the ``@objcMembers`` Swift attribute."

(This attribute has no effect on this class itself or its members, even when imported in Swift -- only on Swift extensions & subclasses.)
