            Bug ID: 41529
           Summary: __managed__ memory space specifier support
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: CUDA
          Assignee: unassignedclangbugs at nondot.org
          Reporter: jules at penuchot.com
                CC: llvm-bugs at lists.llvm.org

Allows to declare a variable that sits in the managed memory space and can
therefore be referenced by both host & device code, see:

https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#managed-specifier

It would be a great improvement, allowing regular variables to be passed as
references to global functions is really lacking.
