These should all be vectorized with -O3 -mavx512dq:

--cut here--
#define N 1024

long long ll[N];
unsigned long long ull[N];

float f[N];
double d[N];

void ll2f (void)
{
  int i;

  for (i = 0; i < N; i++)
    f[i] = ll[i];
}

void ull2f (void)
{
  int i;

  for (i = 0; i < N; i++)
    f[i] = ull[i];
}

void ll2d (void)
{
  int i;

  for (i = 0; i < N; i++)
    d[i] = ll[i];
}

void ull2d (void)
{
  int i;

  for (i = 0; i < N; i++)
    d[i] = ull[i];
}

void f2ll (void)
{
  int i;

  for (i = 0; i < N; i++)
    ll[i] = f[i];
}

void f2ull (void)
{
  int i;

  for (i = 0; i < N; i++)
    ull[i] = f[i];
}

void d2ll (void)
{
  int i;

  for (i = 0; i < N; i++)
    ll[i] = d[i];
}

void d2ull (void)
{
  int i;

  for (i = 0; i < N; i++)
    ull[i] = d[i];
}
--cut here--

Currently, the compiles vectorizes only ll2d and d2ll.
