Yes, initially the idea was to use it for look up the right function. But now each DSO will call GOMP_offload_register, and pass unique pointer to __OPENMP_TARGET__ (host_table) for this DSO. Then gomp_register_images_for_device registers all this host tables in the plugin. And when libgomp calls device_get_table_func, the plugin returns the joint table for all DSO's. -- Ilya
