            Bug ID: 71257
           Summary: OpenMP declare simd linear with ref modifier doesn't
                    accept references to non-integer/non-pointer
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jakub at gcc dot gnu.org
  Target Milestone: ---

struct S { int a; };
#pragma omp declare simd linear(ref(a):1)              // { dg-bogus "applied
to non-integral non-pointer variable" }
int foo (S &a);

is not accepted, while it should be.  The requirement that linear clause refers
only to arguments with integer/pointer type or reference to integer/pointer
type applies only when the ref modifier is not used, otherwise the only
requirement is that the argument has reference type.
