Hi Alex, thanks for CCing me!

Comment at: include/clang/Basic/DiagnosticSemaKinds.td:1157
+def err_objc_method_unsupported_param_ret_type : Error<
+ "%0 %select{parameter|return value}1 is unsupported for this target">;

----------------
s/return value/return type/? Also, It would be nice to mention what isn't
supported (vector types) and the version that it becomes supported in.
================
Comment at: lib/Sema/SemaDeclObjC.cpp:4337
+ VersionTuple MethodVersion = Method->getVersionIntroduced();
+ if (SemaRef.getASTContext().getTargetInfo().getPlatformMinVersion() >=
+ AcceptedInVersion &&
----------------
I wonder if this is the right place to check this. If we're compiling using a
new SDK, but deploying back before vector types were supported we will diagnose
a method declared in a header even if it is never called. We should probably
hook this into DiagnoseAvailabilityOfDecl (in SemaExpr.cpp), which is called
whenever a method is actually used, and diagnose it then.
