            Bug ID: 39668
           Summary: [X86][SSE] Use maskmovdqu for masked stores for
                    unsupported types
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: X86
          Assignee: [email protected]

                    [email protected], [email protected]

maskmovdqu could be used for targets which don't have wider masked store or
extract instructions, although its a non-temporal store and on some targets a
microcoded nightmare.....
