--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
>From reading oacc_verify_routine_clauses, it seems that from OpenACC pragmas on
a FUNCTION_DECL "omp declare target" attribute will have always non-NULL
TREE_VALUE and (at least right now - for host/nohost we use separate attribute)
from OpenMP pragmas will have NULL TREE_VALUE.  So oacc_verify_routine_clauses
either could complain about mixing OpenMP and OpenACC pragmas on the same decl,
or could allow NULL TREE_VALUE and treat it as something (say seq).
