        * config/rs6000/rs6000.c (vrsave_operation): Recognize SETs in
        parallel.
        (is_gpr_return_reg): New.
        (rs6000_emit_prologue): Call generate_set_vrsave with additional
        argument.  Save only registers in the mask.  Attach
        REG_FRAME_RELATED_EXPR note to altivec offsets.  Do not call
        rs6000_frame_related when saving VRSAVE.
        (rs6000_emit_epilogue): Call generate_set_vrsave with additional
        argument.  Restore only registers in the mask.  Restore altivec
        registers after we restore CR.
        (generate_set_vrsave): New parameter epiloguep.  Generate unspec
        sets instead of clobbers for call saved registers.
        (altivec_frame_fixup): New.

This patch is fine.

Thanks, David
