I think you also want to test C++ `std::atomic` as well as regular `volatile`. ================ Comment at: test/Sema/atomic-expr-stmt.c:7 + //CHECK: %atomic-load = load atomic i32, i32* %a.addr seq_cst, align 4 + //CHECK: store atomic i32 %atomic-load, i32* %tmp seq_cst, align 4 + //CHECK: %0 = load i32, i32* %tmp, align 4 ---------------- Why is there a store to `a` here? ================ Comment at: test/Sema/atomic-expr-stmt.c:9 + //CHECK: %0 = load i32, i32* %tmp, align 4 + //CHECK: store i32 %0, i32* %b.addr, align 4 +} ---------------- What's in `%tmp`? I'd expect the value loaded from `a` to be stored to `b`.
