------- Additional Comments From irar at il dot ibm dot com 2005-04-25 09:58 -------
The vectorizer fails to determine dependence between: (*a_38)[D.719_49] and
(*a_38)[D.718_51], since it fails to determine that both of the data-refs have
the same base, *a_38. This is already fixed in autovect branch, and I am
working on a patch to bring the changes in data-refs analysis to mainline.
