// Test will build a module TestModule that depends on OtherModule and LeafModule (built from other.swift and leaf.swift).
|

//
|
|
// RUN: echo 'public func LeafFunc() -> Int { return 10; }' >%t/leaf.swift

// Phase 1: build LeafModule into a .swiftinterface file with -swift-version 4:
|
|
//
|
|
// RUN: %target-swift-frontend -swift-version 4 -I %t -module-cache-path %t/modulecache -emit-parseable-module-interface-path %t/LeafModule.swiftinterface -module-name LeafModule %t/leaf.swift -typecheck

// Phase 2: build OtherModule into a .swiftinterface file with -swift-version 4.2:
|
|
//
|
|
// RUN: %target-swift-frontend -swift-version 4.2 -I %t -module-cache-path %t/modulecache -emit-parseable-module-interface-path %t/OtherModule.swiftinterface -module-name OtherModule %t/other.swift -enable-parseable-module-interface -typecheck

// Phase 3: build TestModule in -swift-version 5 and import both of these:

//

// RUN: %target-swift-frontend -swift-version 5 -I %t -module-cache-path %t/modulecache -module-name TestModule %s -enable-parseable-module-interface -typecheck

//
|
