// This test checks that the value of the symbols.swift-module-loading-mode
// setting is respected when loading Swift modules.
// Note: It intentionally does not check the only-interface or prefer-interface
// modes as this also causes the Swift stdlib to be loaded via its module
// interface file, which slows down this test considerably.
// REQUIRES: swift
// RUN: rm -rf %t && mkdir %t
// Setup generates a dylib and .swiftinterface for A.swift as is, but generates
// the .swiftmodule from a modified version a A.swift where the 'FromInterface'
// type has been renamed to 'FromSerialized'. This means that the 'testValue'
// variable will have a different type depending on whether the module was
// loaded via the .swiftinterface or .swiftmodule.
// RUN: mkdir %t/mcp
// RUN: mkdir %t/lib
// RUN: cp %S/Inputs/A.swift %t/AA.swift
// RUN: %target-swiftc -module-name AA -emit-module-interface-path %t/lib/AA.swiftinterface -emit-library -o %t/lib/libAA%target-shared-library-suffix %t/AA.swift
// RUN: sed -e 's/FromInterface/FromSerialized/g' %t/AA.swift | %target-swiftc -module-name AA -emit-module -o %t/lib/AA.swiftmodule -
// RUN: rm %t/AA.swift
// This is the input provided to lldb. It intentionally assigns 'testValue' to
// a variable of the incorrect type so we can tell via the produced diagnostic
// whether the .swiftinterface or .swiftmodule was used.
