Jakub Jelinek 7c8f7639c5 re PR middle-end/35549 (Invalid use of copy-in/out for shared vars in nested parallels)
PR middle-end/35549
	* omp-low.c (maybe_lookup_decl): Constify first argument.
	(use_pointer_for_field): Change last argument from bool to
	omp_context *.  Disallow shared copy-in/out in nested
	parallel if decl is shared in outer parallel too.
	(build_outer_var_ref, scan_sharing_clauses,
	lower_rec_input_clauses, lower_copyprivate_clauses,
	lower_send_clauses, lower_send_shared_vars): Adjust callers.

	* testsuite/libgomp.c/pr35549.c: New test.
