[PATCH] D126023: [MSVC, ARM64] Add __writex18 intrinsics

[Reid Kleckner via Phabricator via cfe-commits]

rnk added a comment.

I was unable to find any documentation for the meaning of AArch64 addrspace(256), and I wasn't able to figure it out after studying the code in llvm/lib/Target/AArch64 for ten minutes or so. The change seems fine, but please add some documentation as a follow-up. X86 has some of its address spaces documented here, not that this is the best place:
