<dl><dt><code>.lcomm </code><var>symbol</var><code> , </code><var>length</var><code>[, </code><var>alignment</var><code>]</code><dd>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>This directive is only available for COFF based x86 targets.
