aaron.ballman added inline comments.
================
Comment at: clang/include/clang/Basic/Attr.td:104
+def ObjCClassMethod
+ : SubsetSubject<ObjCMethod, [{!S->isInstanceMethod()}],
----------------
This change is no longer needed.
================
Comment at: clang/include/clang/Basic/AttrDocs.td:3584
+The name may be a compound Swift name. For a type, enum constant, property, or
+variable declaration, the name must be a simple or qualified identifier.
+ }];
----------------
A code example showing proper usage would be appreciated.
================
Comment at: clang/lib/Sema/SemaDeclAttr.cpp:4289
+ if (Inline->getName() != Name && !Inline->isImplicit()) {
+ Diag(Inline->getLocation(), diag::warn_attribute_ignored) << Inline;
+ Diag(CI.getLoc(), diag::note_conflicting_attribute);

Not really, no. The warning diagnostic itself just says that the attribute is
ignored, which is the effect but not the rationale. The note (which is easier
for folks to ignore) says the attribute is conflicting, but conflicting with
*what* (there could be a half dozen attributes on the same declaration, for
instance).

Should such function signatures be rejected here though? (If so, can you add a
test for that case as well as a test using a K&R C declaration like `void f()`?)
