            Bug ID: 88602
           Summary: Consider adding ext_vector_type for better clang
                    compatibility
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hubicka at gcc dot gnu.org
  Target Milestone: ---

Clang has attribute ext_vector_type which is like vector_size but it accepts
number of lanes.  This is used by some vector code and while it can be replaced
by multiplication by sizeof (elt_type) it may be good idea to add it.
