Sounds very useful for SPU code. I look forward to trying it out.
Toying with the idea, the following seems like a potentially useful C++
form of the proposed extension :
struct A {
virtual void foo();
};
struct B : public A {
virtual void foo();
};
A* a;
...
__builtin_expect_call (a->foo, B::foo)();
