--- Comment #3 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
I confirm the results in comment 0 with revisions r254869 and r255053, except I
get 'always zero' with 'unrolled do-loop' and '-O1'.
With revision r254940, the 'unrolled do-loop' is parallelized with '-O1',
'-O2', and '-Ofast' only, with a wrong result for '-O1'. The other tests are
parallelized with '-O1' and '-O2' only, with a wrong result in both cases.
For all revisions the 'unrolled do-loop' is parallelized with
'-ftree-parallelize-loops=4 -Ofast' only, with the right result.
