• Anastasia's reply on RFC. http://lists.llvm.org/pipermail/cfe-dev/2020-July/066192.html
• We discussed different approaches for handling address spaces in SYCL mode. Decided to continue discussion on proposed approach with re-using OpenCL attributes as described in the mailing list. Based on the feedback from Anastasia, we can either commit existing patch https://reviews.llvm.org/D80932 or add SYCL-specific address space attributes.
