I have checked the implementation of rs6000 and arm and executed
programs in rs6000
In both the pragma is to defined around a declaration. More over based
on the pragma the attribute of the function in set in
'set_default_type_attributes'.
So with this implementation i don't think it is possible to toggle the
attribute within a function in which they are being callled. Maybe it
might be possible to toggle the attribute between compilational units.
Am i right?
