 9.11.1 D30V Options
 -------------------
 
 The Mitsubishi D30V version of 'as' has a few machine dependent options.
 
 '-O'
      The D30V can often execute two sub-instructions in parallel.  When
      this option is used, 'as' will attempt to optimize its output by
      detecting when instructions can be executed in parallel.
 
 '-n'
      When this option is used, 'as' will issue a warning every time it
      adds a nop instruction.
 
 '-N'
      When this option is used, 'as' will issue a warning if it needs to
      insert a nop after a 32-bit multiply before a load or 16-bit
      multiply instruction.
