; We want to check that when the CU attaches ranges use the correct ContextCU.
; In the following example, after accessing `@foo`, `bar` an `inlined_baz` are created in `foo.swift` CU.
; Setting ranges in `@bar` will then use `bar.swift` CU.
; An incorrect address is eventually calculated based on Base.

; The origin code is:
; foo.swift
; import AppKit.NSLayoutConstraint
; public class Foo {
;     public var c: Int {
;         get {
;             Int(NSLayoutConstraint().constant)
;         }
;         set {
;         }
;     }
; }
; main.swift
; // no mapping for range
; let f: Foo! = nil

; After LTO, `main.swift` will create a global variable, then `Foo` (and relative DIE) created in `main.swift` CU.
