You can look at that in gdb:

(gdb) b tree-inline.c:inlinable_function_p

Then run for some time until you hit the breakpoint, and do:

(gdb) p (fn->decl.u1.i * 10)

That's your stmt count: 130 if you repace "some code" with "return;":

template <bool f>
struct blah {
	void foo() { if (f) { return; } }
};

void bar()
{
	blah<false>().foo();
}

Yes. 130. I can only: ouch.
