<h3 class="section">4.9 <code>ld</code> and MSP430</h3>
|
||
|
|
<p>For the MSP430 it is possible to select the MPU architecture. The flag ‘<samp>-m [mpu type]</samp>’
|
||
|
|
will select an appropriate linker script for selected MPU type. (To get a list of known MPUs
|
||
|
|
just pass ‘<samp>-m help</samp>’ option to the linker).

||
|
|
</p>
|

|
|
<a name="index-MSP430-extra-sections"></a>
|
||
|
|
<p>The linker will recognize some extra sections which are MSP430 specific:
|

|
|
</p>
|
||
|
|
<dl compact="compact">
|

|

<dt><code>‘<samp>.vectors</samp>’</code></dt>

|
