<p><a name="index-g_t_0040code_007bfill_007d-directive-341"></a><a name="index-writing-patterns-in-memory-342"></a><a name="index-patterns_002c-writing-in-memory-343"></a><var>repeat</var>, <var>size</var> and <var>value</var> are absolute expressions.
|
|
This emits <var>repeat</var> copies of <var>size</var> bytes. <var>Repeat</var>
|
|
may be zero or more. <var>Size</var> may be zero or more, but if it is
|
|
more than 8, then it is deemed to have the value 8, compatible with
|
|
other people's assemblers. The contents of each <var>repeat</var> bytes
|
|
is taken from an 8-byte number. The highest order 4 bytes are
|
|
zero. The lowest order 4 bytes are <var>value</var> rendered in the
|
|
byte-order of an integer on the computer <samp><span class="command">as</span></samp> is assembling for.
|
|
Each <var>size</var> bytes in a repetition is taken from the lowest order
|
|
<var>size</var> bytes of this number. Again, this bizarre behavior is
|
|
compatible with other people's assemblers.
|
|
|
|
<p><var>size</var> and <var>value</var> are optional.
|
|
If the second comma and <var>value</var> are absent, <var>value</var> is
|
|
assumed zero. If the first comma and following tokens are absent,
|
|
<var>size</var> is assumed to be 1.
