491 // The Gnu codegen passes in an exclusive upper bound for the overall range,
492 // but the libguide dispatch code expects an inclusive upper bound, hence the
493 // "end - incr" 5th argument to KMP_DISPATCH_INIT (and the " ub - str" 11th
494 // argument to __kmp_GOMP_fork_call).
495 //
496 // Conversely, KMP_DISPATCH_NEXT returns and inclusive upper bound in *p_ub,
497 // but the Gnu codegen expects an excluside upper bound, so the adjustment
498 // "*p_ub += stride" compenstates for the discrepancy.
499 //
500 // Correction: the gnu codegen always adjusts the upper bound by +-1, not the
501 // stride value. We adjust the dispatch parameters accordingly (by +-1), but
502 // we still adjust p_ub by the actual stride value.
503 //
504 // The "runtime" versions do not take a chunk_sz parameter.
505 //
506 // The profile lib cannot support construct checking of unordered loops that
507 // are predetermined by the compiler to be statically scheduled, as the gcc
508 // codegen will not always emit calls to GOMP_loop_static_next() to get the
509 // next iteration. Instead, it emits inline code to call omp_get_thread_num()
510 // num and calculate the iteration space using the result. It doesn't do this
511 // with ordered static loop, so they can be checked.
