|
|
<a name="index-dc-directive"></a>
|
|
|
|
<p>The <code>.dc</code> directive expects zero or more <var>expressions</var> separated by
|
|
commas. These expressions are evaluated and their values inserted into the
|
|
current section. The size of the emitted value depends upon the suffix to the
|
|
<code>.dc</code> directive:
|
|
</p>
|
|
<dl compact="compact">
|
|
<dt><code>‘<samp>.a</samp>’</code></dt>
|
|
<dd><p>Emits N-bit values, where N is the size of an address on the target system.
|
|
</p></dd>
|
|
<dt><code>‘<samp>.b</samp>’</code></dt>
|
|
<dd><p>Emits 8-bit values.
|
|
</p></dd>
|
|
<dt><code>‘<samp>.d</samp>’</code></dt>
|
|
<dd><p>Emits double precision floating-point values.
|
|
</p></dd>
|
|
<dt><code>‘<samp>.l</samp>’</code></dt>
|
|
<dd><p>Emits 32-bit values.
|
|
</p></dd>
|
|
<dt><code>‘<samp>.s</samp>’</code></dt>
|
|
<dd><p>Emits single precision floating-point values.
|
|
</p></dd>
|
|
<dt><code>‘<samp>.w</samp>’</code></dt>
|
|
<dd><p>Emits 16-bit values.
|
|
Note - this is true even on targets where the <code>.word</code> directive would emit
|
|
32-bit values.
|
|
</p></dd>
|
|
<dt><code>‘<samp>.x</samp>’</code></dt>
|
|
<dd><p>Emits long double precision floating-point values.
|
|
</p></dd>
|
|
</dl>
|
|
|
|
<p>If no suffix is used then ‘<samp>.w</samp>’ is assumed.
|
|
</p>
|
|
<p>The byte ordering is target dependent, as is the size and format of floating
|
|
point values.
