From 87eaa3c525eb65775e6d77403b83a273a2397099 Mon Sep 17 00:00:00 2001 From: Jonathan Wakely Date: Fri, 12 Feb 2021 10:36:18 +0000 Subject: [PATCH] libstdc++: Add unused attributes to shared_ptr functions This avoids some warnings when building with -fno-rtti because the function parameters are only used when RTTI is enabled. libstdc++-v3/ChangeLog: * include/bits/shared_ptr_base.h (__shared_ptr::_M_get_deleter): Add unused attribute to parameter. * src/c++11/shared_ptr.cc (_Sp_make_shared_tag::_S_eq): Likewise. --- libstdc++-v3/include/bits/shared_ptr_base.h | 2 +- libstdc++-v3/src/c++11/shared_ptr.cc | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/libstdc++-v3/include/bits/shared_ptr_base.h b/libstdc++-v3/include/bits/shared_ptr_base.h index 15707f8e74a..b24900b2008 100644 --- a/libstdc++-v3/include/bits/shared_ptr_base.h +++ b/libstdc++-v3/include/bits/shared_ptr_base.h @@ -450,7 +450,7 @@ _GLIBCXX_BEGIN_NAMESPACE_VERSION } virtual void* - _M_get_deleter(const std::type_info& __ti) noexcept + _M_get_deleter(const type_info& __ti [[__gnu__::__unused__]]) noexcept { #if __cpp_rtti // _GLIBCXX_RESOLVE_LIB_DEFECTS diff --git a/libstdc++-v3/src/c++11/shared_ptr.cc b/libstdc++-v3/src/c++11/shared_ptr.cc index 13e2d520199..4678fbeffe2 100644 --- a/libstdc++-v3/src/c++11/shared_ptr.cc +++ b/libstdc++-v3/src/c++11/shared_ptr.cc @@ -97,7 +97,7 @@ _GLIBCXX_BEGIN_NAMESPACE_VERSION #endif bool - _Sp_make_shared_tag::_S_eq(const type_info& ti) noexcept + _Sp_make_shared_tag::_S_eq(const type_info& ti [[gnu::unused]]) noexcept { #if __cpp_rtti return ti == typeid(_Sp_make_shared_tag);
