--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Actually, I don't see how inscan be implemented on taskloop, so I'd say both 5.1 and 5.2 are wrong and it should be neither distribute nor taskloop are constituent. #pragma omp target parallel for #pragma omp target parallel for simd #pragma omp target simd should work fine, those just map(tofrom:) the reduction variable.
