sorry for the delay @sarnex 

I have 2 questions:

- It seems strange to have different address spaces for 32/64. I understand you probably don't care about 32, but it is tested.
- why mapping to generic ? This would conflict with https://github.com/intel/llvm/blob/sycl/sycl/doc/design/spirv-extensions/SPV_INTEL_function_pointers.asciidoc if you want a proper implementation.
