I have runtime test in https://reviews.llvm.org/D134268
openmp/libomptarget/test/mapping/target_has_device_addr.c where

void bar() {

  short x[10];
  short *xp = &x[0];
  
  x[1] = 111;

#pragma omp target data map(tofrom : xp [0:2]) use_device_addr(xp [0:2])
#pragma omp target has_device_addr(xp [0:2])

  {
    xp[1] = 222;
    // CHECK: 222
    printf("%d %p\n", xp[1], &xp[1]);
  }
  // CHECK: 222
  printf("%d %p\n", xp[1], &xp[1]);

}
