// REQUIRES: !(default-cxx-stdlib=libc++)

// Windows is unsupported because we use the Unix path separator `/` in the test.
// Unlike the Darwin driver, the MachO driver doesn't add any framework search paths,

// Unlike the Darwin driver, the MachO driver doesn't default to libc++, and unless
// CLANG_DEFAULT_CXX_STDLIB is libc++ it won't add any search paths.

// Verify that embedded uses can swap in alternate usr/include and usr/local/include directories.
// usr/local/include is specified in the driver as -internal-isystem, however, the driver generated
// paths come before the paths in the driver arguments. In order to keep usr/local/include in the
// same position, -isystem has to be used instead of -Xclang -internal-isystem. There isn't an
// -externc-isystem, but it's ok to use -Xclang -internal-externc-isystem since the driver doesn't
// use that if -nostdlibinc or -nostdinc is passed.
// RUN: %clang -x c++ -stdlib=libc++ -target arm64-apple-none-macho -isysroot %S/Inputs/MacOSX15.1.sdk \

// The ordering of these flags doesn't matter, and so this test is a little
// fragile. i.e. all of the -internal-isystem paths will be searched before the
// -internal-externc-isystem ones, and their order on the command line doesn't
// matter. The line order here is just the current order that the driver writes
// the cc1 arguments.
