From: "hubicka at ucw dot cz" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug libstdc++/109442] Dead local copy of std::vector not removed from function Date: Tue, 14 May 2024 13:47:55 +0000 [thread overview] Message-ID: <bug-109442-4-BBw6INAr2A@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-109442-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109442 --- Comment #21 from Jan Hubicka <hubicka at ucw dot cz> --- This patch attempts to add __builtin_operator_new/delete. So far they are not optimized, which will need to be done by extra flag of BUILT_IN_ code. also the decl.cc code can be refactored to be less of cut&paste and I guess has_builtin hack to return proper value needs to be moved to C++ FE. However the immediate problem I run into is that libstdc++ testuiste fails due to lack of std::nothrow overrides. I wonder how to get that working?
