================
Comment at: clang/test/OpenMP/barrier_codegen.cpp:22
+// CLANGCG-NOT: readonly
+// IRBUILDER:      ; Function Attrs: nofree nosync nounwind readonly
+// IRBUILDER-NEXT: declare i32 @__kmpc_global_thread_num(%struct.ident_t*)
----------------
Not sure about correct use of `nosync` and `readonly` attributes. OpenMP runtime uses lazy initialization of the runtime library and when any runtime function is called, the inner parts of the OpenMP runtime are initialized automatically. It may use some sync primitives and may modify memory, I assume. Same about `nofree`.
