|
||
|
|
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. <var>Symbol</var>
|
||
|
|
is not declared global (see <a href="Global.html#Global"><code>.global</code></a>), so is normally
|
||
|
|
not visible to <code>ld</code>.
|
||
|
|
|
||
|
|
<p>Some targets permit a third argument to be used with <code>.lcomm</code>. This
|
||
|
|
argument specifies the desired alignment of the symbol in the bss section.
|
||
|
|
|
||
|
|
<p>The syntax for <code>.lcomm</code> differs slightly on the HPPA. The syntax is
|
||
|
|
‘<samp><var>symbol</var><span class="samp"> .lcomm, </span><var>length</var></samp>’; <var>symbol</var> is optional.
