|
<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>-mlongcall</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.
