how about:
```
void check(uint64_t *a, uint64_t *b) {
__builtin_arm_get_sme_state(a, b);
}
```
with a couple of run lines for various platforms? if `a` and `b` were `unsigned
long *` you'd get an error about the type mismatch on an LLP64 system like:
```
error: cannot initialize a parameter of type 'unsigned long long *' with an
lvalue of type 'unsigned long *'
```
Likewise, if they were `unsigned long long *`, you'd get the error on an LP64
system.
