(gomp_copy_dev2dev): New prototype. * libgomp.map (OACC_2.6.1): New; add acc_memcpy_device{,_async}. * libgomp.texi (acc_memcpy_device): New. * oacc-mem.c (memcpy_tofrom_device): Change to take from/to device boolean; use memcpy not memmove; add early return if size == 0 or same device + same ptr. (acc_memcpy_to_device, acc_memcpy_to_device_async, acc_memcpy_from_device, acc_memcpy_from_device_async): Update. (acc_memcpy_device, acc_memcpy_device_async): New. * openacc.f90 (acc_memcpy_device, acc_memcpy_device_async): Add interface. * openacc_lib.h (acc_memcpy_device, acc_memcpy_device_async): Likewise. * openacc.h (acc_memcpy_device, acc_memcpy_device_async): Add prototype. * plugin/plugin-gcn.c (GOMP_OFFLOAD_openacc_async_host2dev): Update comment. (GOMP_OFFLOAD_openacc_async_dev2host): Update call. (GOMP_OFFLOAD_openacc_async_dev2dev): New. * plugin/plugin-nvptx.c (cuda_memcpy_dev_sanity_check): New. (GOMP_OFFLOAD_dev2dev): Call it. (GOMP_OFFLOAD_openacc_async_dev2dev): New. * target.c (gomp_copy_dev2dev): New. (gomp_load_plugin_for_device): Load dev2dev and async_dev2dev. * testsuite/libgomp.oacc-c-c++-common/acc_memcpy_device-1.c: New test. * testsuite/libgomp.oacc-fortran/acc_memcpy_device-1.f90: New test.
