8.7.1 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.
