Tobias Burnus 8b9e559fe7 libgomp: cuda.h and omp_target_memcpy_rect cleanup ... Fixes for commit r14-2792-g25072a477a56a727b369bf9b20f4d18198ff5894 "OpenMP: Call cuMemcpy2D/cuMemcpy3D for nvptx for omp_target_memcpy_rect", namely: In that commit, the code was changed to handle shared-memory devices; however, as pointed out, omp_target_memcpy_check already set the pointer to NULL in that case. Hence, this commit reverts to the prior version. In cuda.h, it adds cuMemcpyPeer{,Async} for symmetry for cuMemcpy3DPeer (all currently unused) and in three structs, fixes reserved-member names and remove a bogus 'const' in three structs. And it changes a DLSYM to DLSYM_OPT as not all plugins support the new functions, yet. include/ChangeLog: * cuda/cuda.h (CUDA_MEMCPY2D, CUDA_MEMCPY3D, CUDA_MEMCPY3D_PEER): Remove bogus 'const' from 'const void *dst' and fix reserved-name name in those structs. (cuMemcpyPeer, cuMemcpyPeerAsync): Add. libgomp/ChangeLog: * target.c (omp_target_memcpy_rect_worker): Undo dim=1 change for GOMP_OFFLOAD_CAP_SHARED_MEM. (omp_target_memcpy_rect_copy): Likewise for lock condition. (gomp_load_plugin_for_device): Use DLSYM_OPT not DLSYM for memcpy3d/memcpy2d. * plugin/plugin-nvptx.c (GOMP_OFFLOAD_memcpy2d, GOMP_OFFLOAD_memcpy3d): Use memset 0 to nullify reserved and unused src/dst fields for that mem type; remove '{src,dst}LOD = 0'.		2023-07-29 13:25:03 +02:00
