9.8.1 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.
