llvm/llvm/test/CodeGen/SPIRV/const-composite.ll

; This test is to ensure that OpConstantComposite reuses a constant when it's
; already created and available in the same machine function. In this test case
; it's `1` that is passed implicitly as a part of the `foo` function argument
; and also takes part in a composite constant creation.
