Value type must be arithmetic type

[jinz2014]

When building the DPCT codes from the CUDA codes (https://github.com/zjin-lcf/HeCBench/blob/master/src/atomicAggregate-cuda/main.cu) with an Intel LLVM compiler, the compile reports the following message. Could you reproduce the issue ? Thanks.

static assertion failed due to requirement 'std::is_arithmetic_v<int *>': Value type must be arithmetic type.
  303 |   static_assert(std::is_arithmetic_v<T>, "Value type must be arithmetic type.");

main.cpp:15:18: note: in instantiation of function template specialization 'dpct::match_any_over_sub_group<int *>' requested here
   15 |     mask = dpct::match_any_over_sub_group(item_ct1.get_sub_group(), tmask, ptr);

[jinz2014]

Is there a SYCL version for match_any (i.e. sycl::match_any_over_sub_group) ?

After updating the DPCT codes, I ran the CUDA and DPCT programs on a V100 GPU:

@jinz2014 There is no SYCL version for match_any, but we may could replace the arithmetic type check with trivially copyable type check.

[jinz2014]

I see. Could we propose adding "match_any" in the SYCL standard ? Thanks.

@jinz2014 I think so. You can file an extension feature request on https://github.com/intel/llvm/issues, like https://github.com/intel/llvm/tree/sycl/sycl/doc/extensions shows, it should be added to https://github.com/intel/llvm/tree/sycl/sycl/doc/extensions/proposed first.
