        * config/rs6000/rs6000-protos.h (rs6000_secondary_reload_memory):
        Use machine mode, not enum machine_mode in the prototype.

        * config/rs6000/rs6000.h (FLOAT128_IEEE_P): New helper macros to
        classify 128-bit floating point support.
        (FLOAT128_IBM_P): Likewise.
        (FLOAT128_VECTOR_P): Likewise.
        (FLOAT128_2REG_P): Likewise.
        (SCALAR_FLOAT_MODE_NOT_VECTOR_P): Likewise.
        (SLOW_UNALIGNED_ACCESS): Add IEEE 128-bit floating point support.
        (HARD_REGNO_CALLER_SAVE_MODE): Likewise.
        (HARD_REGNO_CALL_PART_CLOBBERED): Likewise.

        * config/rs6000/rs6000.c (rs6000_hard_regno_nregs_internal): Drop
        tests against TFmode/TDmode, since those modes do not use VSX
        addresses.
        (rs6000_hard_regno_mode_ok): Add IEEE 128-bit floating point
        support.
        (rs6000_init_hard_regno_mode_ok): Use new helper macros instead of
        tests against TFmode, etc.
        (invalid_e500_subreg): Add tests against IFmode/KFmode.
        (reg_offset_addressing_ok_p): Likewise.
        (rs6000_legitimate_offset_address_p): Likewise.
        (rs6000_legitimize_address): Likewise.
        (rs6000_legitimize_reload_address): Likewise.
        (rs6000_legitimate_address_p): Clean up tests against TFmode and
        TDmode to use the new helper macros, which will include IFmode and
        KFmode.
        (rs6000_emit_move): Likewise.
        (rs6000_darwin64_record_arg_recurse): Likewise.
        (print_operand): Likewise.
        (rs6000_member_type_forces_blk): Treat IEEE 128-bit floating point
        that uses a single vector register as a vector and not as a
        floating point register in terms of the calling sequence.
        (rs6000_discover_homogeneous_aggregate): Likewise.
        (rs6000_return_in_memory): Likewise.
        (init_cumulative_args): Likewise.
        (rs6000_function_arg_boundary): Likewise.
        (rs6000_function_arg_advance_1): Likewise.
        (rs6000_function_arg): Likewise.
        (rs6000_pass_by_reference): Likewise.
        (rs6000_gimplify_va_arg): Likewise.
        (rs6000_secondary_reload_memory): Use machine_mode not enum
        machine mode.
        (rs6000_split_multireg_move): Use new helper macros.
        (spe_func_has_64bit_regs_p): Likewise.
        (rs6000_output_function_epilogue): Add IFmode/KFmode support.
        (output_toc): Use new helper macros.
        (rs6000_register_move_cost): Likewise.
        (rs6000_function_value): Add IEEE 128-bit floating point calling
        sequence support.
        (rs6000_libcall_value): Likewise.
        (rs6000_scalar_mode_supported_p): Add support for IEEE 128-bit
        floating point support.
        (rs6000_vector_mode_supported_p): Likewise.
