--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Variant which also is valid C:

#pragma omp declare target
  int data[]=3D{5};
#pragma omp end declare target

inline int foo(int idx) { return data[idx]; }

int main()
{
  int i;
  #pragma omp target map(to:i)
    i =3D foo(0);
  return i;
}


Result as follows; enclosing the 'foo' in the declare-target block has no
effect.


With g++ this still fails with:

bar2.cc:2:7: error: variable 'data' has been referenced in offloaded code b=
ut
hasn't been marked to be included in the offloaded code
    2 |   int data[]=3D{5};
      |       ^
lto1: fatal error: errors during merging of translation units


But with cc it fails with:

unresolved symbol foo
mkoffload: fatal error: ...=
