9.10.1 D10V Options
-------------------
The Mitsubishi D10V version of 'as' has a few machine dependent options.
'-O'
The D10V 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.
'--nowarnswap'
To optimize execution performance, 'as' will sometimes swap the
order of instructions. Normally this generates a warning. When
this option is used, no warning will be generated when instructions
are swapped.
'--gstabs-packing'
'--no-gstabs-packing'
'as' packs adjacent short instructions into a single packed
instruction. '--no-gstabs-packing' turns instruction packing off
if '--gstabs' is specified as well; '--gstabs-packing' (the
default) turns instruction packing on even when '--gstabs' is
specified.
