|
|
<a name="index-mcr16c"></a>
|
|
<p>Generate code for CR16C or CR16C+ architecture. CR16C+ architecture
|
|
is default.
|
|
</p>
|
|
</dd>
|
|
<dt><code>-msim</code></dt>
|
|
<dd><a name="index-msim-2"></a>
|
|
<p>Links the library libsim.a which is in compatible with simulator. Applicable
|
|
to ELF compiler only.
|
|
</p>

|
</dd>
|
|
<dt><code>-mint32</code></dt>
|
|
<dd><a name="index-mint32"></a>
|
|
<p>Choose integer type as 32-bit wide.

|
|
<p>Choose a data model. The choices for <var>model</var> are ‘<samp>near</samp>’,
|
|
‘<samp>far</samp>’ or ‘<samp>medium</samp>’. ‘<samp>medium</samp>’ is default.
|
|
However, ‘<samp>far</samp>’ is not valid with <samp>-mcr16c</samp>, as the
|
|
CR16C architecture does not support the far data model.
