|

|
|
|
||
|
|
<p>The RS/6000 and PowerPC targets define one pragma for controlling
|
||
|
|
whether or not the <code>longcall</code> attribute is added to function
|
||
|
|
declarations by default. This pragma overrides the <samp><span class="option">-mlongcall</span></samp>
|
||
|
|
option, but not the <code>longcall</code> and <code>shortcall</code> attributes.
|
||
|
|
See <a href="RS_002f6000-and-PowerPC-Options.html#RS_002f6000-and-PowerPC-Options">RS/6000 and PowerPC Options</a>, for more information about when long
|
||
|
|
calls are and are not necessary.

|
||
|

<dl>
|
||
|
|
<dt><code>longcall (1)</code><dd><a name="index-pragma_002c-longcall-4168"></a>Apply the <code>longcall</code> attribute to all subsequent function
|

declarations.
|
