5.47.2 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 section IBM RS/6000 and PowerPC Options, for more information about when long
calls are and are not necessary.
-
longcall (1) -
Apply the
longcallattribute to all subsequent function declarations. -
longcall (0) Do not apply the
longcallattribute to subsequent function declarations.
