// CHECK: CTU loaded AST file

// FIXME: In this test case, we cannot use the on-demand-parsing approach to
//        load the external TU.
//
//        In the Darwin system, the target triple is determined by the driver,
//        rather than using the default one like other systems. However, when
//        using bare `clang -cc1`, the adjustment is not done, which cannot
//        match the one loaded with on-demand-parsing (adjusted triple).
//        We bypass this problem by loading AST files, whose target triple is
//        also unadjusted when generated via `clang -cc1 -emit-pch`.
//
//        Refer to: https://discourse.llvm.org/t/60762
//
//        This is also the reason why the test case of D75665 (introducing
//        the on-demand-parsing feature) is enabled only on Linux.
