[nvptx] Add support for a per-worker broadcast buffer and barrier
Add support for a per-worker broadcast buffer and barrier, to be used for
openacc vector_length larger than warp-size.
2019-01-07 Tom de Vries <tdevries@suse.de>
* config/nvptx/nvptx.c (oacc_bcast_partition): Declare.
(nvptx_option_override): Init oacc_bcast_partition.
(nvptx_init_oacc_workers): New function.
(nvptx_declare_function_name): Call nvptx_init_oacc_workers.
(nvptx_needs_shared_bcast): New function.
(nvptx_find_par): Generalize to enable vectors to use shared-memory
to propagate state.
(nvptx_shared_propagate): Initialize vector bcast partition and
synchronization state.
(nvptx_single): Generalize to enable vectors to use shared-memory
to propagate state.
(nvptx_process_pars): Likewise.
(nvptx_set_current_function): Initialize oacc_broadcast_partition.
* config/nvptx/nvptx.h (struct machine_function): Add
bcast_partition and sync_bar members.
