Can't you instead just have 2 IVs, one for where we read the vector elt and
one for where we write it if the 2 are diff

Hi,
Consider this openmp example:
...
/* { dg-do link } */
#define N 100
int
main ()
{
int a[N];
int i, x;
int c;
c = 1;
#pragma omp target
for (i = 0; i < 100; i++)
a[i] = 0;
if (c)
__builtin_unreachable ();
#pragma omp target
for (i = 0; i < 100; i++)
a[i] = 1;
