            Bug ID: 59909
           Summary: Quad memory bootstrap issues on little endian
                    powerpc64 power8 systems
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: meissner at gcc dot gnu.org

Using the current sources, the GCC 4.9 compiler will not bootstrap if the
default target is power8 on a little endian system.  The cause is the new quad
word load/store support does not deal with swapping words after doing the load,
and before doing the store.
