__attribute__((no_dup))

This attribute is used to force Offload™ not to duplicate the given method for SPU.

static int foo() __attribute__((no_dup));

static void func()
{
	offloadThread_t handle = __offload()
	{
		int bar = foo(); // will fail at compile time, as foo is no allowed to be duplicated
	};
}

It is useful to ban methods that you do not want any programmers to ever call from the SPU.
