libgomp/ * libgomp.h (struct splay_tree_key_s): Substitute dynamic_refcount field for virtual_refcount. (enum gomp_map_vars_kind): Add GOMP_MAP_VARS_OPENACC_ENTER_DATA. (gomp_free_memmap): Remove prototype. * oacc-init.c (acc_shutdown_1): Iteratively call gomp_remove_var instead of calling gomp_free_memmap. * oacc-mem.c (acc_map_data): Use virtual_refcount instead of dynamic_refcount. (acc_unmap_data): Open code instead of forcing target_mem_desc's to_free field to NULL then calling gomp_unmap_vars. Handle REFCOUNT_INFINITY on target blocks. (goacc_enter_data): Rename to... (goacc_enter_datum): ...this. Remove MAPNUM parameter and special handling for mapping groups. Use virtual_refcount instead of dynamic_refcount. Use GOMP_MAP_VARS_OPENACC_ENTER_DATA for map_map_vars_async call. Re-do lookup for target pointer return value. (acc_create, acc_create_async, acc_copyin, acc_copyin_async): Call renamed goacc_enter_datum function. (goacc_exit_data): Rename to... (goacc_exit_datum): ...this. Update for virtual_refcount semantics. (acc_delete, acc_delete_async, acc_delete_finalize, acc_delete_finalize_async, acc_copyout, acc_copyout_async, acc_copyout_finalize, acc_copyout_finalize_async): Call renamed goacc_exit_datum function. (gomp_acc_remove_pointer, find_pointer): Remove functions. (find_group_last, goacc_enter_data_internal, goacc_exit_data_internal): New functions. (GOACC_enter_exit_data): Use goacc_enter_data_internal and goacc_exit_data_internal helper functions. * target.c (gomp_map_vars_internal): Handle GOMP_MAP_VARS_OPENACC_ENTER_DATA. Update for virtual_refcount semantics. (gomp_unmap_vars_internal): Update for virtual_refcount semantics. (gomp_load_image_to_device, omp_target_associate_ptr): Zero-initialise virtual_refcount field instead of dynamic_refcount. (gomp_free_memmap): Remove function. * testsuite/libgomp.oacc-c-c++-common/unmap-infinity-1.c: New test. * testsuite/libgomp.c-c++-common/unmap-infinity-2.c: New test. * testsuite/libgomp.oacc-c-c++-common/pr92843-1.c: Add XFAIL.
