--- Comment #2 from ktkachov at gcc dot gnu.org ---
Smaller testcase for -Ofast -floop-interchange on aarch64:
int a, b, c, e, f, g;
int d[1];
static int *h = &c;
long i;
int
fn1 (short p1)
{
return p1 + a;
}
void
fn2 ()
{
for (; f; f++)
{
int *j = &g;
e = 1;
for (; e; e++)
{
i = b ?: b;
*j ^= fn1 (d[e]);
if (*h)
break;
}
}
}
