Detailed Description

Support OMP 6.0 target memory management Expected offload runtime entries.

Returns number of resources and list of unique resource IDs in "resouces". Runtime needs to invoke this twice to get the number of resources, allocate space for the resource IDs, and finally let offload runtime write resource IDs in "resources". int __tgt_get_mem_resources(int num_devices, const int *devices, int host_access, omp_memspace_handle_t memspace, int *resources);

Redirects omp_alloc call to offload runtime. void *__tgt_omp_alloc(size_t size, omp_allocator_handle_t allocator);

Redirects omp_free call to offload runtime. void __tgt_omp_free(void *ptr, omp_allocator_handle_t);

		int *	resources )

inline

Obtain resource information from offload runtime.

We assume offload runtime backends maintain a list of unique resource IDS.
