; The goal of @test_typesX() cases is to ensure that a correct pointer type
; is deduced from the Value argument of OpAtomicLoad/OpAtomicStore. There is
; no need to add more pattern matching rules to be sure that the pointer type
; is valid, it's enough that `spirv-val` considers the output valid as it
; checks the same condition while validating the output.
