--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed. here is a testcase with only `-O3 -fno-tree-dce` as this basically
does what `-fno-inline` and `-fno-ipa-cp` cause:
```
short a, d;
int b, c, f, g, h, i, j[2], o;
__attribute__((const)) int s(char r);
int main() {
int l, m, k, n;
if (b) {
char p;
for (; p >= 0; p--) {
int e[] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 1, 1, 0, 0, 0,
1, 0, 0, 1, 1, 0, 0, 0, 1, 0, 0, 1, 1, 0, 0, 0, 1,
0, 0, 1, 1, 0, 0, 0, 1, 0, 0, 1, 1, 0, 0};
if (j[p]) {
int q[1];
i = o;
o = q[h];
if (g)
n = d;
m = 4;
for (; m; m--) {
if (l)
k |= c;
if (a)
break;
}
}
s(n);
f |= b;
}
}
return 0;
}
```
