// Tests the bindings generated for a CUDA offloading target for different
// combinations of:
// - Number of gpu architectures;
// - Host/device-only compilation;
// - User-requested final phase - binary or assembly.
// It parallels cuda-phases.cu test, but verifies whether output file is temporary or not.
// It's hard to check whether file name is temporary in a portable
// way. Instead we check whether we've generated a permanent name on
// device side, which appends '-device-cuda-<triple>' suffix.
//
// Test single gpu architecture with complete compilation.
// No intermediary device files should have "-device-cuda..." in the name.
