<p><a name="index-g_t_0040code_007bds_007d-directive-312"></a>This directive emits <var>number</var> copies of <var>fill</var>, each of <var>size</var>
|
||
|
|
bytes. Both <var>number</var> and <var>fill</var> are absolute expressions. If the
|
||
|
|
comma and <var>fill</var> are omitted, <var>fill</var> is assumed to be zero. The
|
||
|
|
<var>size</var> suffix, if present, must be one of:
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt><code>‘</code><samp><span class="samp">.b</span></samp><code>’</code><dd>Emits single byte values.
|
||
|
|
<br><dt><code>‘</code><samp><span class="samp">.d</span></samp><code>’</code><dd>Emits 8-byte values.
|
||
|
|
<br><dt><code>‘</code><samp><span class="samp">.l</span></samp><code>’</code><dd>Emits 4-byte values.
|
||
|
|
<br><dt><code>‘</code><samp><span class="samp">.p</span></samp><code>’</code><dd>Emits 12-byte values.
|
||
|
|
<br><dt><code>‘</code><samp><span class="samp">.s</span></samp><code>’</code><dd>Emits 4-byte values.
|
||
|
|
<br><dt><code>‘</code><samp><span class="samp">.w</span></samp><code>’</code><dd>Emits 2-byte values.
|
||
|
|
<br><dt><code>‘</code><samp><span class="samp">.x</span></samp><code>’</code><dd>Emits 12-byte values.
|
||
|
|
</dl>
|
||
|
|
|
||
|
|
<p>Note - unlike the <code>.dcb</code> directive the ‘<samp><span class="samp">.d</span></samp>’, ‘<samp><span class="samp">.s</span></samp>’ and ‘<samp><span class="samp">.x</span></samp>’
|
||
|
|
suffixes do not indicate that floating-point values are to be inserted.
|
||
|
|
|
||
|
|
<p>If the <var>size</var> suffix is omitted then ‘<samp><span class="samp">.w</span></samp>’ is assumed.
|
||
|
|
|
||
|
|
<p>The byte ordering is target dependent.
