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.
