+       * pa.c (hppa_init_pic_save): Set rtx_unchanging for
+       PIC_OFFSET_TABLE_SAVE_RTX.
+
        * pa.c (uint32_operand): Don't use long constant >= 2^32.
        (emit_move_sequence): Use HOST_WIDE_INT constants.  Don't worry
        about 32->64 bit sign extension if 32 bit HOST_WIDE_INTs.
