<p><a name="index-g_t_0040code_007bweak_007d-directive-511"></a>This directive sets the weak attribute on the comma separated list of symbol
|
||
|
|
<code>names</code>. If the symbols do not already exist, they will be created.
|
||
|
|
|
||
|
|
<p>On COFF targets other than PE, weak symbols are a GNU extension. This
|
||
|
|
directive sets the weak attribute on the comma separated list of symbol
|
||
|
|
<code>names</code>. If the symbols do not already exist, they will be created.
|
||
|
|
|
||
|
|
<p>On the PE target, weak symbols are supported natively as weak aliases.
|
||
|
|
When a weak symbol is created that is not an alias, GAS creates an
|
||
|
|
alternate symbol to hold the default value.
