|
|
<p><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>
|
|
<p>Both spellings (‘<samp>.globl</samp>’ and ‘<samp>.global</samp>’) are accepted, for
|
|
compatibility with other assemblers.
|
|
</p>
|
|
<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.
