            Bug ID: 22826
           Summary: constexpr and CUDA
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

Clang considers constexpr as calls and does regular caller-callee analysis to
determine if it is valid to call a function from either a host or device
function. constexpr can be completely evaluated at compile which results in a
constant instead of a function call and so the same analysis need not occur.
