* config/gcn/gcn.c (gcn_goacc_validate_dims): Remove
no-flag_worker-partitioning assertion.
(TARGET_GOACC_WORKER_PARTITIONING): Define target hook to true.
* config/gcn/gcn.opt (flag_worker_partitioning): Change default to 1.
libgomp/
* plugin/plugin-gcn.c (gcn_exec): Change default number of workers to
16.
