From 51d702f3baf73aa4016b9798045d13318074ca1e Mon Sep 17 00:00:00 2001 From: Jonathan Wakely Date: Wed, 16 Aug 2023 21:29:46 +0100 Subject: [PATCH] libstdc++: Disable PCH for tests that rely on include order These tests expect to be able to #undef a feature test macro and then include to get it redefined. But if has already been included by the PCH then including it again does nothing and the macro remains undefined. libstdc++-v3/ChangeLog: * testsuite/24_iterators/move_iterator/p2520r0.cc: Add no_pch. * testsuite/std/format/functions/format.cc: Likewise. * testsuite/std/format/functions/format_c++23.cc: Likewise. --- libstdc++-v3/testsuite/24_iterators/move_iterator/p2520r0.cc | 1 + libstdc++-v3/testsuite/std/format/functions/format.cc | 1 + libstdc++-v3/testsuite/std/format/functions/format_c++23.cc | 1 + 3 files changed, 3 insertions(+) diff --git a/libstdc++-v3/testsuite/24_iterators/move_iterator/p2520r0.cc b/libstdc++-v3/testsuite/24_iterators/move_iterator/p2520r0.cc index 883d6cc09e00..e36ac574a8ec 100644 --- a/libstdc++-v3/testsuite/24_iterators/move_iterator/p2520r0.cc +++ b/libstdc++-v3/testsuite/24_iterators/move_iterator/p2520r0.cc @@ -1,5 +1,6 @@ // { dg-options "-std=gnu++20" } // { dg-do compile { target c++20 } } +// { dg-add-options no_pch } // Verify P2520R0 changes to move_iterator's iterator_concept, which we treat // as a DR against C++20. diff --git a/libstdc++-v3/testsuite/std/format/functions/format.cc b/libstdc++-v3/testsuite/std/format/functions/format.cc index a8d5b652a5eb..4db5202815d6 100644 --- a/libstdc++-v3/testsuite/std/format/functions/format.cc +++ b/libstdc++-v3/testsuite/std/format/functions/format.cc @@ -1,5 +1,6 @@ // { dg-options "-std=gnu++20" } // { dg-do run { target c++20 } } +// { dg-add-options no_pch } #include diff --git a/libstdc++-v3/testsuite/std/format/functions/format_c++23.cc b/libstdc++-v3/testsuite/std/format/functions/format_c++23.cc index f20c46cd7e38..3caa70fcdf2d 100644 --- a/libstdc++-v3/testsuite/std/format/functions/format_c++23.cc +++ b/libstdc++-v3/testsuite/std/format/functions/format_c++23.cc @@ -1,4 +1,5 @@ // { dg-do run { target c++23 } } +// { dg-add-options no_pch } // This test does not have -std=gnu++20 in dg-options so that format.cc // can be tested for e.g. -std=c++26 #include "format.cc" -- 2.47.2
