// Check that we correctly determine that the final link command links
// devicelibs together, as far as the driver is concerned. This results in the
// -only-needed flag.
//
// Note we check the names of the various device libraries because that's the
// logic the driver uses.

// Older CUDA versions had versioned libdevice files. We don't support CUDA
// this old in SYCL, but we still test the driver's ability to pick out the
// correctly versioned libdevice. We use Inputs/CUDA_80 which has a full set of
// libdevice files.
