That's because it isn't true.
In fact one of the classical ways for a C function to
return a struct is to be *GIVEN* a pointer, e.g.,
struct Foo f(......) {
...
return x;
}
=>
void f(struct Foo *_hidden, ......) {
...
*_hidden = x;
return;
}
and obviously a C compiler is entitled to return a small struct
in registers if it feels like it.
