For this specific case I do not know what happens under the hood.
For an externally callable function, a function descriptor is generated in the
ADA by the _binder_. From the LLVM point of view, the ADA would still be empty.
The simple example is:
```
void empty() {}
```
Here, the ADA is empty. Still, the binder generates the function descriptor. A
caller of this function can use a function descriptor in its own compilation
unit:
```
DC R(empty)
DC V(empty)
```
I would expect that I get a binder error on `R(empty)` if no associated data
area was given for the code section. But I have not tried.
