            Bug ID: 47368
           Summary: OMP map clause restriction change from 4.5 to 5.0 on
                    "list iterms of map clause in the same construnct must
                    not share original storge"
           Product: clang
           Version: 5.0
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: OpenMP

OMP 4.5:

List items of map clauses in the same construct must not share
original storage.

OMP 5.0:

List items of the map clauses on the same construct must not share original
storage unless they are the same lvalue expression or array section.

So we should allow:


int scalar = 80;
#pragma omp target  map (alloc: scalar) map(to: scalar)
