Jakub Jelinek 8ca5b2a2d4 re PR c++/26943 ([gomp] firstprivate + lastprivate uses inefficient barrier) ... PR c++/26943 * omp-low.c (maybe_lookup_decl_in_outer_ctx): New function. (build_outer_var_ref): Use maybe_lookup_decl_in_outer_ctx to find if var will be a global variable even in the nested context. (omp_copy_decl): Only check for global variable at the end, it might be overridden in outer contexts. (scan_sharing_clauses): For global variables don't create a field. (lower_rec_input_clauses): Do nothing for global shared variables. Emit a barrier at the end of ILIST if there were any decls in both firstprivate and lastprivate clauses. (lower_send_clauses): Do nothing for global variables except for COPYIN. * testsuite/libgomp.c/pr26943-1.c: New test. * testsuite/libgomp.c/pr26943-2.c: New test. * testsuite/libgomp.c/pr26943-3.c: New test. * testsuite/libgomp.c/pr26943-4.c: New test. * testsuite/libgomp.c++/pr27337.C: Remove barrier. * testsuite/libgomp.c++/pr26943.C: New test.
