   Disables all deprecation warnings in SYCL runtime headers, including SYCL
   1.2.1 deprecations.
 
+- **SYCL_DISABLE_DEVICE_COPYABLE_CHECKS**
+
+  Makes `sycl::is_device_copyable_v<T>` report `true` for every type, and
+  disables all diagnostics that the SYCL headers issue when a type does not
+  satisfy the device copyability requirements of the SYCL specification. 
+  Passing an object whose type is not actually device copyable to a device
+  results in undefined behavior. The user takes responsibility for ensuring
+  that every type passed to a device can be copied by the implementation.
+
 - **SYCL_DISABLE_IMAGE_ASPECT_WARNING**
 
   Disables warning diagnostic issued when calling `device::has(aspect::image)`
