We had a customer bug report about the behavior of
info::device::execution_capabilities
for non-OpenCL devices. It turns out that the spec isn't clear about this. This PR clarifies that an exception should be thrown, which is consistent with our behavior forinfo::device::profile
andinfo::device::preferred_interop_user_sync
, which are also inherited from OpenCL. Another option would be to return an empty vector, so we could debate that if people think that's better.I also think we should deprecate this query, which is consistent with the other queries that are specific to the OpenCL backend. This PR deprecates the query in SYCL-NEXT, though I would also be open to retroactively deprecating it in SYCL 2020 with the rationale that we deprecated the other OpenCL-specific queries and simply forgot this one.
