|
|
|
|
<p><a name="index-alignment-for-NEON-instructions-726"></a>Some NEON load/store instructions allow an optional address
|
|
alignment qualifier.

The ARM documentation specifies that this is indicated by
|
|
‘<samp><span class="samp">@ </span><var>align</var></samp>’. However GAS already interprets
|
|
the ‘<samp><span class="samp">@</span></samp>’ character as a "line comment" start,
|
|
so ‘<samp><span class="samp">: </span><var>align</var></samp>’ is used instead. For example:
|
|
|
|
<pre class="smallexample"> vld1.8 {q0}, [r0, :128]
|
|
</pre>
|
|
</body></html>
