; 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)

; }
|
|
; }
|
|
; 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.
