Almost there.
Unlike OpenCL abs, but like C and C++ abs, in SYCL 2020, taking the absolute value of a signed type produces a signed result and the behavior is undefined if the absolute value is not representable (i.e. if the input is the greatest negative value), so do not check that the SYCL results match the reference results for this case.

Similar to sycl::abs, sycl::abs_diff now has undefined behavior for unrepresentable results. This patch changes the generated tests for abs_diff to avoid UB, similar to how it was done for abs in KhronosGroup#831. Signed-off-by: Larsen, Steffen <steffen.larsen@intel.com>
