From 038c0afa893f8cb2277ff44be3e2c09cfab4bc0c Mon Sep 17 00:00:00 2001 From: Jonathan Wakely Date: Fri, 15 Sep 2023 21:37:46 +0100 Subject: libstdc++: Fix 29_atomics/headers/atomic/types_std_c++2a_neg.cc for C++23 This test fails when run as C++23 because the PCH includes which declares ::memory_order, invalidating the test's assumptions. Disable PCH so that the test verifies that doesn't declare ::memory_order, as originally intended. Also fix the using-declaration which would be invalid even if the type was declared in the global namespace, and adjust the expected error. libstdc++-v3/ChangeLog: * testsuite/29_atomics/headers/atomic/types_std_c++2a_neg.cc: Fix test to work for C++23 and C++26 too. --- .../testsuite/29_atomics/headers/atomic/types_std_c++2a_neg.cc | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'libstdc++-v3') diff --git a/libstdc++-v3/testsuite/29_atomics/headers/atomic/types_std_c++2a_neg.cc b/libstdc++-v3/testsuite/29_atomics/headers/atomic/types_std_c++2a_neg.cc index 8eba8bf..65199ce 100644 --- a/libstdc++-v3/testsuite/29_atomics/headers/atomic/types_std_c++2a_neg.cc +++ b/libstdc++-v3/testsuite/29_atomics/headers/atomic/types_std_c++2a_neg.cc @@ -1,5 +1,8 @@ // { dg-options "-std=gnu++2a" } -// { dg-do compile { target c++2a } } +// { dg-do compile { target c++20 } } +// Disable PCH because includes which declares +// memory_order in the global namespace. +// { dg-add-options no_pch } // Copyright (C) 2019-2023 Free Software Foundation, Inc. // @@ -23,7 +26,7 @@ void test01() { // Not global scoped, only namespace std. - using memory_order; // { dg-error "expected nested-name-specifier" } + using ::memory_order; // { dg-error "has not been declared" } constexpr auto relaxed = memory_order::relaxed; // { dg-error "has not been declared" } constexpr auto consume = memory_order::consume; // { dg-error "has not been declared" } constexpr auto acquire = memory_order::acquire; // { dg-error "has not been declared" } -- cgit v1.1
