--- Comment #20 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
I looked at the output of=20

gfortran -Ofast -funroll-loops -march=3Dnative -mtune=3Dnative -fopt-info-v=
ec
mp_prop_design.f90  2>&1 | wc -l

in the Polyhedron testsuite, and I can confirm it really shows
much more vectorization than before.  So, I'm glad that part seems
to be fixed.

Regarding auto-parallelization: I can confirm your observation under
Linux, it doesn't do any more than on Windows.

I think I will open up meta-PR and make this PR depend on it.=
