<dt><code>.lcomm <var>symbol</var> , <var>length</var>[, <var>alignment</var>]</code></dt>
<dd><p>Reserve <var>length</var> (an absolute expression) bytes for a local common
denoted by <var>symbol</var>.  The section and value of <var>symbol</var> are
those of the new local common.  The addresses are allocated in the bss
section, so that at run-time the bytes start off zeroed.  Since
<var>symbol</var> is not declared global, it is normally not visible to
<code>ld</code>.  The optional third parameter, <var>alignment</var>,
specifies the desired alignment of the symbol in the bss section.
</p>
<p>This directive is only available for COFF based x86 targets.

<dt><code>.largecomm <var>symbol</var> , <var>length</var>[, <var>alignment</var>]</code></dt>
<dd><p>This directive behaves in the same way as the <code>comm</code> directive
except that the data is placed into the <var>.lbss</var> section instead of
the <var>.bss</var> section <a href="Comm.html#Comm">Comm</a>.
</p>
<p>The directive is intended to be used for data which requires a large
amount of space, and it is only available for ELF based x86_64
targets.

</dd>
<dt><code>.value <var>expression</var> [, <var>expression</var>]</code></dt>
<dd><p>This directive behaves in the same way as the <code>.short</code> directive,
taking a series of comma separated expressions and storing them as
two-byte wide values into the current section.
