| <p>These options are defined specifically for the CR16 ports. |
| </p> |
| <dl compact="compact"> |
| <dt><code>-mmac</code></dt> |
| <dd><a name="index-mmac"></a> |
| <p>Enable the use of multiply-accumulate instructions. Disabled by default. |
| </p> |
| </dd> |
| <dt><code>-mcr16cplus</code></dt> |
| <dt><code>-mcr16c</code></dt> |
| <dd><a name="index-mcr16cplus"></a> |
| <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> |
| </dd> |
| <dt><code>-mbit-ops</code></dt> |
| <dd><a name="index-mbit_002dops"></a> |
| <p>Generates <code>sbit</code>/<code>cbit</code> instructions for bit manipulations. |
| </p> |
| </dd> |
| <dt><code>-mdata-model=<var>model</var></code></dt> |
| <dd><a name="index-mdata_002dmodel"></a> |
| <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. |
