1 9.9.1 D10V Options
1 ------------------
1 
1 The Mitsubishi D10V version of 'as' has a few machine dependent options.
1 
1 '-O'
1      The D10V can often execute two sub-instructions in parallel.  When
1      this option is used, 'as' will attempt to optimize its output by
1      detecting when instructions can be executed in parallel.
1 '--nowarnswap'
1      To optimize execution performance, 'as' will sometimes swap the
1      order of instructions.  Normally this generates a warning.  When
1      this option is used, no warning will be generated when instructions
1      are swapped.
1 '--gstabs-packing'
1 '--no-gstabs-packing'
1      'as' packs adjacent short instructions into a single packed
1      instruction.  '--no-gstabs-packing' turns instruction packing off
1      if '--gstabs' is specified as well; '--gstabs-packing' (the
1      default) turns instruction packing on even when '--gstabs' is
1      specified.
