; Sanity check MachO Platform support: Call a no-op method (returning int 0) on
; an ObjC object. This test checks that we correctly auto-identify this as a
; MachO target, configure MachOPlatform support, and correctly register the
; class metadata and method selector with the Objective-C runtime.
