<p><a name="index-CR16-Options-1520"></a>
|

|
|
These options are defined specifically for the CR16 ports.
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt><code>-mmac</code><dd><a name="index-mmac-1521"></a>Enable the use of multiply-accumulate instructions. Disabled by default.
|
||
|
|
|
||
|
|
<br><dt><code>-mcr16cplus</code><dt><code>-mcr16c</code><dd><a name="index-mcr16cplus-1522"></a><a name="index-mcr16c-1523"></a>Generate code for CR16C or CR16C+ architecture. CR16C+ architecture
|
||
|
|
is default.
|
||
|
|
|
||
|
|
<br><dt><code>-msim</code><dd><a name="index-msim-1524"></a>Links the library libsim.a which is in compatible with simulator. Applicable
|
||
|
|
to ELF compiler only.
|
||
|
|
|
||
|
|
<br><dt><code>-mint32</code><dd><a name="index-mint32-1525"></a>Choose integer type as 32-bit wide.
|
||
|
|
|
||
|
|
<br><dt><code>-mbit-ops</code><dd><a name="index-mbit_002dops-1526"></a>Generates <code>sbit</code>/<code>cbit</code> instructions for bit manipulations.
|
||
|
|
|
||
|
|
<br><dt><code>-mdata-model=</code><var>model</var><dd><a name="index-mdata_002dmodel-1527"></a>Choose a data model. The choices for <var>model</var> are ‘<samp><span class="samp">near</span></samp>’,
|
||
|
|
‘<samp><span class="samp">far</span></samp>’ or ‘<samp><span class="samp">medium</span></samp>’. ‘<samp><span class="samp">medium</span></samp>’ is default.
|
||
|
|
However, ‘<samp><span class="samp">far</span></samp>’ is not valid with <samp><span class="option">-mcr16c</span></samp>, as the
|
||
|
|
CR16C architecture does not support the far data model.
