! This test checks lowering of OpenMP DO Directive(Worksharing) for different
! types of loop iteration variable, lower bound, upper bound, and step.
!REQUIRES: shell
!RUN: bbc -fopenmp -emit-hlfir %s -o - 2>&1 | FileCheck %s
!CHECK: OpenMP loop iteration variable cannot have more than 64 bits size and will be narrowed into 64 bits.
