It turned out that this patch fails with LTO and partitions, causing fails at runtime such as libgomp: Duplicate node via libgomp/splay-tree.c's splay_tree_insert.
In the test case, the problem occurred for functions - namely main._omp_fn.* on the host. If the code is run in LTO context, the filtering-out should have already happen via the stream-out/stream-in and hence no additional check is needed for omp_finish_file. OK? Tobias PS: The streaming-in is done via: input_offload_tables (/* do_force_output = */ !flag_ltrans); ----------------- Mentor Graphics (Deutschland) GmbH, Arnulfstraße 201, 80634 München / Germany Registergericht München HRB 106955, Geschäftsführer: Thomas Heurung, Alexander Walter
