            Bug ID: 19509
           Summary: Port post-indexed ldN/stN selection to ARM64 from
                    AArch64
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: AArch64
          Assignee: unassignedbugs at nondot.org
          Reporter: t.p.northover at gmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

AArch64 appears to have the ability to select post-indexed NEON loads & stores,
but ARM64 won't ever use these. The code appears reasonably generic but
substantial: it will need copying across a bit carefully.
