Other test cases I would like to see are:
```
// As a global variable where there is no stack address to get.
// This should be diagnosed as an error?
void *ptr = __builtin_stack_address();
inline void *what() {
return __builtin_stack_address();
}
void func() {
void *ptr = what(); // Is this getting the stack address of? The inline
function or is it getting the stack address of the caller? Or depends on
optimization level?
}
```
Should we also have tests for what happens with naked functions or other kind
of odd situations where the stack may be different from the normal case?
