--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For unsigned long:
void f(unsigned long *a)
{
unsigned long t0 = a[0];
unsigned long t1 = a[1];
a[1] = t0;
a[0] = t1;
}
void f0(unsigned long *a)
{
__uint128_t t0 = ((__uint128_t *)a)[0];
__uint128_t t1 = t0>>sizeof(unsigned long)*8;
__uint128_t t2 = t0<<sizeof(unsigned long)*8;
((__uint128_t*)a)[0] = t1 | t2;
}
--- CUT ---
Note I will file f0 not producing rolq soon.
