! { dg-do compile }

! { dg-options "-Wunused-variable -Wunused-parameter" }

! This tests the fix for PR18111 in which some artificial declarations

! were being listed as unused parameters:

! (i) Array dummies, where a copy is made;

! (ii) The dummies of "entry thunks" (ie. the articial procedures that

! represent ENTRYs and call the "entry_master" function; and

! (iii) The __entry parameter of the entry_master function, which

! indentifies the calling entry thunk.

! All of these have DECL_ARTIFICIAL (tree) set.

module foo

  implicit none

contains

!This is the original problem

  subroutine bar(arg1, arg2, arg3, arg4, arg5)

    character(len=80), intent(in) :: arg1

    character(len=80), dimension(:), intent(in) :: arg2

    integer, dimension(arg4), intent(in) :: arg3

    integer, intent(in) :: arg4

    character(len=arg4), intent(in) :: arg5

    print *, arg1, arg2, arg3, arg4, arg5

  end subroutine bar

! This ICED with the first version of the fix because gfc_build_dummy_array_decl

! sometimes NULLS sym->backend_decl; taken from aliasing_dummy_1.f90

  subroutine foo1 (slist, i)

    character(*), dimension(*) :: slist

    integer i

    write (slist(i), '(2hi=,i3)') i

  end subroutine foo1

! This tests the additions to the fix that prevent the dummies of entry thunks

! and entry_master __entry parameters from being listed as unused.

  function f1 (a)

    integer, dimension (2, 2) :: a, b, f1, e1
