| // General tests that the header search paths for libc++ detected by the driver |
| // and passed to CC1 are correct on Darwin platforms. This test copies the clang |
| // binary, which won't work if it uses any dynamic libraries (BUILD_SHARED_LIBS, |
| // LLVM_LINK_LLVM_DYLIB, or CLANG_LINK_CLANG_DYLIB). |

| // ---------------------------------------------------------------------------- |
| // On Darwin, libc++ can be installed in one of the following places: |
| // 1. Alongside the compiler in <install>/include/c++/v1 |
| // 2. Alongside the compiler in <clang-executable-folder>/../include/c++/v1 |
| // 3. In a SDK (or a custom sysroot) in <sysroot>/usr/include/c++/v1 |
| |
| // The build folders do not have an `include/c++/v1`; create a new |
| // local folder hierarchy that meets this requirement. |
| // Note: this might not work with weird RPATH configurations. |
