--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I am going to handle this since I have seen this in other places.
Note we also need to handle:
```
MEM <unsigned long> [(char * {ref-all})&z] = 0;
MEM <unsigned char[24]> [(char * {ref-all})&z + 8B] = {};
```
Which can show up via:
```
char z[32];
void
foo1(void)
{
char z1[8];
char z2[24];
__builtin_memset (z1, 0, 8);
__builtin_memcpy (z, z1, 8);
__builtin_memset (z2, 0, 24);
__builtin_memcpy (z+8, z2, 24);
}
```
Or after PR 36602 is handled.
