            Bug ID: 62278
           Summary: gfc_check_dependency should also check for TARGET
                    attribute
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Keywords: missed-optimization
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org

When playing around with https://gcc.gnu.org/ml/fortran/2014-08/msg00109.html,
using 

  gfc_check_dependency (lhs_expr, rhs_expr, false) 

I saw that for the following, the "P(:)" and "A(:)" expressions are regarded as
potentially depending on each other. However, I fail how that should be
possible as "A" neither has the TARGET nor the POINTER attribute.


integer, save :: A(10)[*]
integer, pointer :: P(:)

P(:) = A(:)[i]
end
