| // 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 |

| // RUN: echo 'import LeafModule' >%t/other.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 |

| // |
| // 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 -typecheck |

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

| // Phase 4: make sure we only compiled LeafModule and OtherModule one time: |
| // |
| // RUN: ls %t/modulecache | grep -c 'LeafModule-.*.swiftmodule' | %FileCheck %s |
| // RUN: ls %t/modulecache | grep -c 'OtherModule-.*.swiftmodule' | %FileCheck %s |
