Coverage increased (+1.2%) to 64.548% when pulling 0423551 on use-dpcpp-built-kernels into 521d277 on master.

Even though, logically, the sycl::kernel produced by dpcpp_kernel::get_fill_kernel has been given all the arguments that command group function object lambda would capture by reference, removing those from DPCTLQueue_SubmitRange results in an incorrect result (test fails).

Thus, duplicating these captured values via set_args appears needed. Perhaps this is to be expected, as the captured values are captured on the host side and must still be sent over to the device.

@diptorupd I have added tests for DCPTLQueue_SubmitNDRange. Expanded tests for int, unsigned int, float and double.

To fix the "generate-coverage" workflow it sufficies to remove linking to dpcpp_kernels static library.

The error is

[100%] Linking CXX executable dpctl_c_api_tests
error: Linking COMDATs named '__profd_dpcpp_kernels.cpp__ZN7__spirvL16initGlobalOffsetILi1EN2cl4sycl2idILi1EEEEET0_v': noduplicates has been violated!
dpcpp: error: sycl-link command failed with exit code 1 (use -v to see invocation)

@diptorupd Is there another way to fix it?

Failures on Linux are due to OpenCL runtime packages being unavailable on PyPI due to limitation on the size of published packages.

So this can be merged.
