/* 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. */
