+       * i386-dis.c (twobyte_has_mandatory_prefix): New variable.
+       (end_codep): Likewise.
+       (mandatory_prefix): Likewise.
+       (active_seg_prefix): Likewise.
+       (ckprefix): Set active_seg_prefix to the active segment register
+       prefix.
+       (seg_prefix): Removed.
+       (get_valid_dis386): Use the last of PREFIX_REPNZ and PREFIX_REPZ
+       for prefix index.  Ignore the index if it is invalid and the
+       mandatory prefix isn't required.
+       (print_insn): Set mandatory_prefix if the PREFIX_XXX prefix is
+       mandatory.  Don't set PREFIX_REPZ/PREFIX_REPNZ/PREFIX_LOCK bits
+       in used_prefixes here.  Don't print unused prefixes.  Check
+       active_seg_prefix for the active segment register prefix.
+       Restore the DFLAG bit in sizeflag if the data size prefix is
+       unused.  Check the unused mandatory PREFIX_XXX prefixes
+       (append_seg): Only print the segment register which gets used.
+       (OP_E_memory): Check active_seg_prefix for the segment register
+       prefix.
+       (OP_OFF): Likewise.
+       (OP_OFF64): Likewise.
+       (OP_DSreg): Set active_seg_prefix to PREFIX_DS if it is unset.
