! 2.15.1.1 Predetermined rules for associated do-loops index variable
! a) The loop iteration variable(s) in the associated do-loop(s) of a do,
! parallel do, taskloop, or distribute construct is (are) private.
! b) The loop iteration variable in the associated do-loop of a simd construct
! with just one associated do-loop is linear with a linear-step that is the
! increment of the associated do-loop.
! c) The loop iteration variables in the associated do-loops of a simd
! construct with multiple associated do-loops are lastprivate.
! d) A loop iteration variable for a sequential loop in a parallel or task
! generating construct is private in the innermost such construct that
! encloses the loop.
! - TBD
! All the tests assume that the do-loops association for collapse/ordered
! clause has been performed (the number of nested do-loops >= n).
