| <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. |

| <p><a name="index-g_t_0040code_007blargecomm_007d-directive_002c-ELF-1140"></a><br><dt><code>.largecomm </code><var>symbol</var><code> , </code><var>length</var><code>[, </code><var>alignment</var><code>]</code><dd>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>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. |
| |
| <p><a name="index-g_t_0040code_007bvalue_007d-directive-1141"></a><br><dt><code>.value </code><var>expression</var><code> [, </code><var>expression</var><code>]</code><dd>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. |
