- <p>These options are defined specifically for the FT32 port.
- </p>
- <dl compact="compact">
- <dt><code>-msim</code></dt>
- <dd><a name="index-msim-3"></a>
- <p>Specifies that the program will be run on the simulator. This causes
- an alternate runtime startup and library to be linked.
- You must not use this option when generating programs that will run on
- real hardware; you must provide your own runtime library for whatever
- I/O functions are needed.
- </p>
- </dd>
- <dt><code>-mlra</code></dt>
- <dd><a name="index-mlra-1"></a>
- <p>Enable Local Register Allocation. This is still experimental for FT32,
- so by default the compiler uses standard reload.
- </p>
- </dd>
- <dt><code>-mnodiv</code></dt>
- <dd><a name="index-mnodiv"></a>
- <p>Do not use div and mod instructions.
- </p>
- </dd>
- <dt><code>-mft32b</code></dt>
- <dd><a name="index-mft32b"></a>
- <p>Enable use of the extended instructions of the FT32B processor.
- </p>
- </dd>
- <dt><code>-mcompress</code></dt>
- <dd><a name="index-mcompress"></a>
- <p>Compress all code using the Ft32B code compression scheme.
- </p>
- </dd>
- <dt><code>-mnopm</code></dt>
- <dd><a name="index-mnopm"></a>
- <p>Do not generate code that reads program memory.
