! Offloading test checking interaction of an
! explicit derived type member mapping of
! an array with bounds when mapped to
! target using a combination of update,
! enter and exit directives.
! REQUIRES: flang, amdgpu

! RUN: %libomptarget-compile-fortran-run-and-check-generic
program main
    type :: scalar_array
        integer(4) :: array(10)
    end type scalar_array

    type(scalar_array) :: scalar_arr

    do I = 1, 10
        scalar_arr%array(I) = I + I
    end do

  !$omp target enter data map(to: scalar_arr%array(3:6))

    ! overwrite our target data with an update.
    do I = 1, 10
        scalar_arr%array(I) = 10
    end do

  !$omp target update to(scalar_arr%array(3:6))

  ! The compiler/runtime is less friendly about read/write out of
  ! bounds when using enter and exit, we have to specifically loop
  ! over the correct range
