[Bug tree-optimization/19049] not vectorizing a fortran loop

--- Comment #7 from irar at il dot ibm dot com 2006-09-19 07:29 --- Even though vectorization of strided accesses is already implemented in the autovect branch (and will be committed to the mainline 4.3), this case contains a store with a gap (store to a[i] without a store to a[i-1]),

--- Additional Comments From irar at il dot ibm dot com 2005-07-26 07:07 --- The data dependence issue was solved by this patch http://gcc.gnu.org/ml/gcc- patches/2005-07/msg01195.html (committed). However, this loop is still not vectorizable because of noncontinuous access. --

--- 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
