423 into the constant offset, or for variable low-bound using
424 POINTER_PLUS_EXPR. For structure element based array sections use
425 GOMP_MAP_ALWAYS_POINTER instead of GOMP_MAP_FIRSTPRIVATE_POINTER.

427 elements are now always mapped even as array section bases,
428 diagnose same var in data sharing and mapping clauses. Diagnose if
429 linear step on declare simd is neither a constant nor a uniform

431 reductions. Diagnose the same var or function appearing multiple
432 times on the same directive. Fix up wording for the to clause if t
433 is neither a FUNCTION_DECL nor a VAR_DECL. Diagnose nonmonotonic
434 modifier on kinds other than dynamic or guided or nonmonotonic
435 modifier together with ordered clause.
