Right, but what do you propose the numbers of source AS IDs to be or should we put CL_KERNEL_ARG_ADDRESS_GLOBAL, etc, as strings instead? I am not sure it's a good idea to tie SPIR and OpenCL together. At the end SPIR is meant to be an IR to compile from different source languages and not just OpenCL.
