// resource directory should be identical to `%clang -print-resource-dir`.
// (Assuming both binaries are built from the same Git checkout.)
// Here we get the expected path by running `%clang -print-resource-dir` and
// then verify `%clang-scan-deps` arrives at the same path by calling the
// `Driver::GetResourcesPath` function.

// Run the compiler and ask it for the resource directory.
//
// With `%clang-scan-deps --resource-dir-recipe invoke-compiler`, the resource
// directory should be identical to `<clang> -print-resource-dir`, where <clang>
// is an arbitrary version of Clang. (This configuration is not really supported.)
// Here we hard-code the expected path into `%t/compiler` and then verify
// `%clang-scan-deps` arrives at the path by actually running the executable.
