openmp/libomptarget/test/offloading/mandatory_but_no_devices.c

// Check that mandatory offloading causes various offloading directives to fail
// when omp_get_num_devices() == 0 even if the requested device is the initial
// device.  This behavior is proposed for OpenMP 5.2 in OpenMP spec github
// issue 2669.
