--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Another testcase (from PR 103399) which shows the issue:
int t1 = -2;
int e(int) __attribute__((noipa));
int e(int f) {
    int t = 0;
  for (int d = 0; d < f; d ++) {
    for (int c = 0; c < ((f ? t1 : 0) ^ t1) + 1; c++)
      t= 42;
  }
 return t;
}
int main() {
  unsigned a = e(1);
  printf("%u\n", a);
  if (a != 42)
    __builtin_abort ();
}
