// Correction: the gnu codegen always adjusts the upper bound by +-1, not the

// we still adjust p_ub by the actual stride value.

//
// The profile lib cannot support construct checking of unordered loops that
// are predetermined by the compiler to be statically scheduled, as the gcc
// codegen will not always emit calls to GOMP_loop_static_next() to get the
// next iteration.  Instead, it emits inline code to call omp_get_thread_num()
// num and calculate the iteration space using the result.  It doesn't do this
// with ordered static loop, so they can be checked.
