--- Comment #12 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2011-01-31 18:46:23 UTC --- > I looked at how to improve translate_scalar_reduction_to_array in > order to avoid the creation of the temporary array, but it seems to be > difficult as the result is written to memory under a different type > than the reduction itself: l12_lower is a real whereas l12 is an > integer: In the original code l12 is real (kind = longreal) as l12_lower, but making the change does not help the vectorization.
