This commit addresses an issue in libgomp’s GOMP_RUNTIME_USM feature by correctly handling pointer attachment for global static variables during target enter/exit data operations when self-mapping is enabled. The accompanying documentation update clarifies unsupported scenarios and removes an outdated reference to self-maps/USM, reflecting the current state of the features.
