here is a better testcase with no undefinedness:
```
int a;
float *b, *c;
void d(char * __restrict e) {
  for (; a; a++, b += 4, c += 4)
    if (*e++) {
      float *f = c;
      f[0] = b[0];
      f[1] = b[1];
      f[2] = b[2];
      f[3] = b[3];
    }
}
```

Just `-O3  -march=armv9-a` is needed.
