Message-ID: <bug-114339-4-RNaZ1f1Tbg@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced testcase:
```
#define vect128 __attribute__((vector_size(16)))

[[gnu::noinline]]
vect128 long f(vect128 long a)
{
        return a <= (vect128 long){0, 9223372036854775807};
}

int main()
{
  vect128 long t = (vect128 long){0, 0};
  t = f(t);
  if (!t[1])
  __builtin_abort();

}
```
