[PATCH] D64600: [ObjC] Add an attribute that "clamps" signed char BOOLs to {0,1}

[Aaron Ballman via Phabricator via cfe-commits]

aaron.ballman added inline comments.


================
Comment at: clang/include/clang/Basic/Attr.td:3279
+def ObjCClampingBool : TypeAttr {
+  let Spellings = [Clang<"objc_clamping_bool">];
+  let Subjects = SubjectList<[TypedefName]>;
----------------
Is there a desire for similar functionality for C's `_Bool` datatype, or other, 
custom datatypes (perhaps `BOOL` from the Win32 APIs)? It seems like this 
attribute could be generalized to apply to any typedef to an integral type.
