  I've revised the comment as such.

  /* When disassembling ex9 instructions, they are annotated with
     the original instructions at the end of line.  For example,

        0x00500122 <+82>:    ex9.it #4          ! movi $r13, 10

     Dissembler needs the symbol table to extract the original instruction
     in _ITB_BASE_ table.  If the object file is changed, reload symbol
     table.  */

  This was used to dump registers and stack and create a gdbinit script,
  so I can use the script to debug backtrace porting issues.
  Anyway, I've removed this command in revised patch.  I think I don't need
  it anymore.

  It still needs more work :p

  Just add our target and send a separate patch for it?
