Testcase
```
subroutine f(a, b, k1, k2, k3, k4)
implicit none
real :: a(:,:,:), b(:,:,:)
integer :: k1, k2, k3, k4
integer :: j1, j2, j3
!$omp target teams distribute parallel do collapse(3)
!$omp tile sizes(1,256,1)
do j1 = 1, k1
do j2 = k2, k3
do j3 = 1, k4
a(j3,j1,j2) = b(j2,j3,j1)
enddo
enddo
enddo
!$omp end tile
!$omp end target teams distribute parallel do
end
```
Compile with
`flang -c -fopenmp -fopenmp-version=60 test.f90`
Result
```
warning: OpenMP support for version 60 in flang is still incomplete
