! Test lowering of OPTIONAL VALUE dummy argument on caller side.
! RUN: %flang_fc1 -emit-hlfir %s -o - | FileCheck %s

! A copy must be made if the actual is a variable (and no copy-out), but care
! has to be take if the actual argument may be absent at runtime: the copy
! must be conditional. When the allocation is dynamic, the temp allocation and
! deallocation are also conditionals.
