These are tests that fail in the next commit without this flag. This does not add -verify-ignore-unrelated to all tests with -verify, only the ones that would fail without it. This is NFC since this flag is currently a no-op.

// '@_private import' is intended to be used to compile "thunks" which contain
|
|
// modified versions of declarations. For this to work properly, name lookup
|
|
// needs to favor declarations in the private import over other imports. This
|
|
// emulates the increased visibility of same-module declarations in the original
|
|
// file, preserving source compatibility as much as possible.
|
|
//
|
|
// In this test:
|
|
//
|
|
// * Module Host contains this file and Host.swift. Note that this file compiles
|
|
// successfully with COMPILING_THUNK undefined.
|
|
// * This file is also built as a thunk with COMPILING_THUNK defined to "edit"
|
|
// it.
|
|
// * We also build three other modules called Most, Ghost, and Toast. Each of
|
|
// these is imported by both Host and the thunk.
|
|
//
|
|
// There are various same-name types scattered throughout these modules. If
|
|
// name lookup selects the right ones for each of the test cases, the compiler
|
|
// will generate the expected diagnostics and the test will pass. If it selects
|
|
// incorrect types, deprecation warnings will be emitted and the test will fail.
|
