------- Comment #2 from matz at gcc dot gnu dot org 2010-09-07 13:27 -------
The patch at http://gcc.gnu.org/ml/gcc-patches/2010-09/msg00548.html
implements support for consecutive loads with negative step. It will
vectorize the first testcase. But not the second one because it only
handled loads, not stores.
