New Revision: 244522

URL: https://gcc.gnu.org/viewcvs?rev=244522&root=gcc&view=rev
Log:
	* plugin/configfrag.ac: For --without-cuda-driver don't initialize
	CUDA_DRIVER_INCLUDE nor CUDA_DRIVER_LIB.  If both
	CUDA_DRIVER_INCLUDE and CUDA_DRIVER_LIB are empty and linking small
	cuda program fails, define PLUGIN_NVPTX_DYNAMIC to 1 and use
	plugin/include/cuda as include dir and -ldl instead of -lcuda as
	library to link ptx plugin against.
	* plugin/plugin-nvptx.c: Include dlfcn.h if PLUGIN_NVPTX_DYNAMIC.
	(CUDA_CALLS): Define.
	(cuda_lib, cuda_lib_inited): New variables.
	(init_cuda_lib): New function.
	(CUDA_CALL_PREFIX): Define.
	(CUDA_CALL_ERET, CUDA_CALL_ASSERT): Use CUDA_CALL_PREFIX.
	(CUDA_CALL): Use FN instead of (FN).
	(CUDA_CALL_NOCHECK): Define.
	(cuda_error, fini_streams_for_device, select_stream_for_async,
	nvptx_attach_host_thread_to_device, nvptx_open_device, link_ptx,
	event_gc, nvptx_exec, nvptx_async_test, nvptx_async_test_all,
	nvptx_wait_all, nvptx_set_clocktick, GOMP_OFFLOAD_unload_image,
	nvptx_stacks_alloc, nvptx_stacks_free, GOMP_OFFLOAD_run): Use
	CUDA_CALL_NOCHECK.
	(nvptx_init): Call init_cuda_lib, if it fails, return false.  Use
	CUDA_CALL_NOCHECK.
	(nvptx_get_num_devices): Call init_cuda_lib, if it fails, return 0.
	Use CUDA_CALL_NOCHECK.
	* plugin/cuda/cuda.h: New file.
	* config.h.in: Regenerated.
	* configure: Regenerated.
