The latest adjustments to lim optimization; which is currently only in
autovect branch; can open an opportunity for store ccp to be applied and
as a result for the vectorizer as well. (as was shown in the example in -
http://gcc.gnu.org/ml/gcc-patches/2007-03/msg01255.html). That is why
autovect branch was chosen. I intend to submit this patch to mainline
soon after committing it to the branch. I'll be happy to propose the
patch for mainline right now, but if it turns out that the patch need
to be considerably revised before it can be committed to mainline,
I wish to commit it to the branch until I revise the implementation.

Thanks,
Revital
