Bug ID: 41609
Summary: static constexpr class members not accepted without
address space qualifier
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: OpenCL
Assignee: unassignedclangb...@nondot.org

Demonstator for problem
I can create constexpr constants without an address space qualifier, but if I
try to create a static constexpr class members (which are essentially just
constexpr constants), clang complains:
error: program scope variable must reside in global or constant address space
The attached test case demonstates the problem.
CUDA has special treatment to allow such constexpr static members. I didn't
read something in the OpenCL spec about this, but out of convenience and
compatibility, I think it should be supported as well.
