/* Remapping of nonmonotonic runtime schedule and maybe nonmonotonic runtime

   schedule loop entrypoints (the used by GCC 9 and later for runtime

   schedule without monotonic or nonmonotonic modifiers).

   RHEL 7 libgomp only implements the GOMP*loop*runtime* entrypoints without

   nonmonotonic in the names, which always implement monotonic scheduling,

   but the library doesn't implement any other scheduling, even in GCC 9

   and monotonic scheduling is a valid implementation of non-monotonic

   scheduling.  */
