preferred way to use dual instruction mode is to explicitly code

<p>The <code>.dual</code>, <code>.enddual</code>, and <code>.atmp</code> directives are available only in the Intel syntax mode.
|
||
|
|
|
||
|
|
<p>Both syntaxes allow for the standard <code>.align</code> directive. However,
|
||
|
|
the Intel syntax additionally allows keywords for the alignment
|
||
|
|
parameter: "<code>.align type</code>", where `type' is one of <code>.short</code>, <code>.long</code>,
|
||
|
|
<code>.quad</code>, <code>.single</code>, <code>.double</code> representing alignments of 2, 4,
|
||
|
|
16, 4, and 8, respectively.
