--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So dom3 was able to optimize that via a jump threading before in GCC 13 but no
longer on the trunk (I don't understand why though).
Anyways the only pass which is able to optimize:
```
int f123(int a, int c, int i)
{
int *d;
if (a) d = &i; else d = &c;
int e = d == &i;
int f = d == &c;
return e | f;
}
```
to `1` is PRE ...
But note
```
int g123();
int h123();
int f123_1(int a, int c, int i)
{
int *d;
if (a) d = &i; else d = &c;
int e = d == &i;
int f = d == &c;
if (e | f)
return h123();
return g123();
}
```
Still can be optimized by dom2 on the trunk (via jump threading).
So how did dom3 miss the original testcase ....
