            Bug ID: 115800
           Summary: PowerPC GCC cannot build a little endian compile if
                    --with-cpu=power5 is used
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: meissner at gcc dot gnu.org
  Target Milestone: ---

The libgfortran and libstdc++-v3 libraries cannot be built if you build a
little endian compiler and set the default cpu to power5.  The reason appears
to be the libraries both assume that if a little endian target is being built,
that IEEE 128-bit floating point is supported.  But power5 does not support the
VSX instruction set and registers, so IEEE 128-bit floating point is not
available.
