-When passed as a `ccall` argument with the `llvmcall` calling convention, an `AddrSpacePtr` will be converted to an LLVM pointer type with the correct address space.
-This type is mainly used to ensure Julia's codegen uses the correct address space when calling LLVM intrinsics.
+A pointer type that more closely resembles LLVM semantics: It includes the pointer address
+space, and will be pass as an actual pointer instead of an integer.

+This type is mainly used to ensure Julia's codegen uses the correct address space when
