We can do two things: - reject the vectype. This is difficult because we see different vectypes for both stores. - massage the access pointer to be a ref-all pointer. This requires re-computing aliasing after the vectorizer. -- rguenth at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- AssignedTo|unassigned at gcc dot gnu |rguenth at gcc dot gnu dot |dot org |org Status|NEW |ASSIGNED Last reconfirmed|2008-11-06 21:38:00 |2008-11-07 10:43:29 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37955
