--- Comment #1 from Sam James <sjames at gcc dot gnu.org> ---
Please always attach testcases. godbolt links are fine, but we want them pasted
inline if not too long or attached as well for completeness.

```
typedef __SIZE_TYPE__ size_t;

struct S1 {
  unsigned char pad1;
  unsigned char val;
};

extern unsigned char t[256];

struct S1 foo(struct S1 a, size_t i) {
  a.val = t[i];

  return __builtin_assoc_barrier(a);
}
```
