; Note: This test is testing that the lowering for atomics matches what we
; currently emit for non-atomics + the atomic restriction. The presence of
; particular lowering detail in these tests should not be read as requiring
; that detail for correctness unless it's related to the atomicity itself.
; (Specifically, there were reviewer questions about the lowering for halfs
; and their calling convention which remain unresolved.)
