  19 // FIXME: In this test case, we cannot use the on-demand-parsing approach to
  20 //        load the external TU.
  21 //
  22 //        In the Darwin system, the target triple is determined by the driver,
  23 //        rather than using the default one like other systems. However, when
  24 //        using bare `clang -cc1`, the adjustment is not done, which cannot
  25 //        match the one loaded with on-demand-parsing (adjusted triple).
  26 //        We bypass this problem by loading AST files, whose target triple is
  27 //        also unadjusted when generated via `clang -cc1 -emit-pch`.
  28 //
  29 //        Refer to: https://discourse.llvm.org/t/60762
  30 //
  31 //        This is also the reason why the test case of D75665 (introducing
  32 //        the on-demand-parsing feature) is enabled only on Linux.
