            Bug ID: 35873
           Summary: misleading data sharing error message for const
                    variable
           Product: OpenMP
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Clang Compiler Support
          Assignee: unassignedclangbugs at nondot.org

void foo(const int rows)
{
        #pragma omp parallel for default(none) firstprivate(rows)
        for (int row = 0; row < rows; ++row)
        {
        }
}

$ clang-cl -Xclang -fopenmp -c test.cpp
test.cpp(4,26):  error: variable 'rows' must have explicitly specified data
sharing attributes

This is very misleading as rows _is_ specified.
It would be better to output something conveying "rows is shared because of
const".
gcc just accepts the code btw.
