// 1) Build the 'Inherited' library and its interface from this file
//
// RUN: %target-build-swift-dylib(%t/%target-library-name(Inherited)) -emit-module-path %t/Inherited.swiftmodule -emit-module-interface-path %t/Inherited.swiftinterface -module-name Inherited %s
// RUN: rm %t/Inherited.swiftmodule
// RUN: %target-swift-typecheck-module-from-interface(%t/Inherited.swiftinterface)

// 2) Check the interface includes the synthesized initializers of the base
// class in the derived class explicitly and uses the '= super' syntax to
// inherit its default arguments.
//
// RUN: %FileCheck --check-prefix=INTERFACE %s < %t/Inherited.swiftinterface

// INTERFACE: public class Base {
// INTERFACE: public init(x: Swift.Int = 45, y: Swift.Int = 98)
// INTERFACE: }
// INTERFACE: public class Derived : Inherited.Base {
// INTERFACE: override public init(x: Swift.Int = super, y: Swift.Int = super)
// INTERFACE: }

// 4) Generate a main.swift file that uses the 'Inherited' library and makes use
// of the inherited default arguments
//
// RUN: echo "import Inherited" > %t/main.swift
// RUN: echo "print(Derived().x)" >> %t/main.swift
// RUN: echo "print(Derived().y)" >> %t/main.swift

// 5) Build and run the executable, checking the defaulted arguments resulted in
// the correct values being stored
//
// RUN: %target-build-swift -I%t -L%t -lInherited -o %t/main %target-rpath(%t) %t/main.swift -swift-version 5

// OUTPUT: 45
