! Test how transformational intrinsic function references are lowered

! RUN: bbc -emit-fir -hlfir=false %s -o - | FileCheck %s

! The exact intrinsic being tested does not really matter, what is
! tested here is that transformational intrinsics are lowered correctly
! regardless of the context they appear into.
