--- Comment #31 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
A question is if #pragma GCC ivdep has similar guarantees/restrictions; the
documentation only disallows certain loop-carried dependencies, in particular
those that would prevent vectorization, so I think it is the same as
unspecified (== infinite) safelen on #pragma omp simd.
