flang/test/Lower/Intrinsics/cmplx.f90

   1 ! This test focus on cmplx with Y argument that may turn out
   2 ! to be absent at runtime because it is an unallocated allocatable,
   3 ! a disassociated pointer, or an optional argument.
   4 ! CMPLX without such argument is re-written by the front-end as a
   5 ! complex constructor that is tested elsewhere.
