           Summary: APFloat does not support IEEEquad
           Product: libraries
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Support Libraries
        AssignedTo: unassignedbugs at nondot.org

IEEE 128 bit values are not supported by APFloat. Also, looking at the code, it
is not clear to me how values with multiple significand words work. It seems
that the code here and in APInt is host endian sensitive. For example,
APInt(80, 2, words) copies the words array into the big int. This seems wrong.
