70 * Since we need to distinguish the three possible cases (no modifier,
71 * monotonic modifier, nonmonotonic modifier), we need separate bits for
72 * each modifier. The absence of monotonic does not imply nonmonotonic,
73 * especially since 4.5 says that the behaviour of the "no modifier" case
74 * is implementation defined in 4.5, but will become "nonmonotonic" in 5.0.
75 *
76 * Since we're passing a full 32 bit value, we can use a couple of high
77 * bits for these flags; out of paranoia we avoid the sign bit.
78 *
79 * These modifiers can be or-ed into non-static schedules by the compiler
80 * to pass the additional information. They will be stripped early in the
81 * processing in __kmp_dispatch_init when setting up schedules, so
82 * most of the code won't ever see schedules with these bits set.
