    * config/rs6000/rs6000.c (rs6000_hard_regno_mode_ok): If we have
    software floating point or no floating point registers, do not
    allow any type in the FPRs.  Eliminate a test for SPE SIMD types
    in GPRs that occurs after we tested for GPRs that would never be
    true.

    * config/rs6000/rs6000.md (mov<mode>_softfloat32, FMOVE64):
    Rewrite tests to use TARGET_DOUBLE_FLOAT and TARGET_E500_DOUBLE,
    since the FMOVE64 type is DFmode/DDmode.  If TARGET_E500_DOUBLE,
    specifically allow DDmode, since that does not use the SPE SIMD
    instructions.
