            Bug ID: 50640
           Summary: OpenMP target clause implicitly scaling loop bounds to
                    uint64_t
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: OpenMP
          Assignee: a.bataev at hotmail.com
          Reporter: huberjn at ornl.gov
                CC: huberjn at ornl.gov, llvm-bugs at lists.llvm.org

When `#pragma omp target teams distribute parallel for` is applied to a loop it
is implicitly scaling the loop's upper bound to be an unsigned long. This
causes warnings if the `-Wsign-compare` option is set even if the comparisons
are of the same type.
