8.4.1 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.
