--- Comment #3 from Arseny Solokha <asolokha at gmx dot com> ---
The following testcase fails for x86_64 w/ the current trunk:
int oh;
__int128 ii, pa;
unsigned __int128 kn;
void
vz (void)
{
while (oh < 1)
{
if (oh <= kn)
{
__int128 *iu;
if (oh == 0)
{
ii |= pa;
if (ii != 0)
while (kn != 0)
++kn;
}
iu = &pa;
kn *= 3;
pa += kn;
}
++oh;
}
}
