--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Might be slightly easier to understand testcase:
```
int a[3], d[3], c;
int f(int e, int b) {
for (; e < 3; e++) {
a[0] = 0;
if (b)
c = b;
d[e] = 0;
a[e] = 0;
}
return e;
}
```
And `-O2 -funswitch-loops -fno-tree-scev-cprop`. I am not sure if the IR coming
out of unswitch is bad or ldist is going wrong.
