6 ;; This test checks that Invoke parameter of OpEnueueKernel instruction meet the
7 ;; following specification requirements in case of enqueueing empty block:
8 ;; "Invoke must be an OpFunction whose OpTypeFunction operand has:
9 ;; - Result Type must be OpTypeVoid.
10 ;; - The first parameter must have a type of OpTypePointer to an 8-bit OpTypeInt.
11 ;; - An optional list of parameters, each of which must have a type of OpTypePointer to the Workgroup Storage Class.
