<p><a name="index-g_t_0040code_007bglobal_007d-directive-352"></a><a name="index-symbol_002c-making-visible-to-linker-353"></a><code>.global</code> makes the symbol visible to <code>ld</code>. If you define
|
||
|
|
<var>symbol</var> in your partial program, its value is made available to
|
||
|
|
other partial programs that are linked with it. Otherwise,
|
||
|
|
<var>symbol</var> takes its attributes from a symbol of the same name
|
||
|
|
from another file linked into the same program.
|
||
|
|
|
||
|
|
<p>Both spellings (‘<samp><span class="samp">.globl</span></samp>’ and ‘<samp><span class="samp">.global</span></samp>’) are accepted, for
|
||
|
|
compatibility with other assemblers.
|
||
|
|
|
||
|
|
<p>On the HPPA, <code>.global</code> is not always enough to make it accessible to other
|
||
|
|
partial programs. You may need the HPPA-only <code>.EXPORT</code> directive as well.
