RS/6000 and PowerPC Pragmas (Using the GNU Compiler Collection (GCC))

6.64.5 RS/6000 and PowerPC Pragmas

The RS/6000 and PowerPC targets define one pragma for controlling whether or not the longcall attribute is added to function declarations by default. This pragma overrides the -mlongcall option, but not the longcall and shortcall attributes. See RS/6000 and PowerPC Options, for more information about when long calls are and are not necessary.

longcall (1): Apply the longcall attribute to all subsequent function declarations.
longcall (0): Do not apply the longcall attribute to subsequent function declarations.
