--- Comment #8 from janus at gcc dot gnu.org ---
Indeed all the items from comment 1 to 3 seems to be handled. Below is a test
case, whose dump shows a _final call being created for all of them.

The only exception is realloc-on-assignment, which is not implemented yet for
CLASS variables, but there is PR 43366 to track that.

Therefore this PR can be closed, I think.



program p

type t
end type t

type u
  class(t), allocatable :: c
end type

class(t), allocatable :: a,b
type(u), allocatable :: uu
integer :: i
character(len=100) :: str

allocate(a,b,uu)

! (1) explicit deallocation
deallocate(a)

! (4) STAT and ERRMSG
deallocate(a,stat=i,errmsg=str)
if (i/=0) print *,i,str

! (5) dealloc of comp.
deallocate(uu)

! (6) move_alloc
call move_alloc(b,a)

contains

  subroutine out (x)
    ! (2) intent(out)
    class(t), intent(out) :: x
  end subroutine

  subroutine sub ()
    ! (3) out of scope
    class(t), allocatable :: local
    allocate(local)
  end subroutine

end
