From: "pinskia at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c/105628] False positive with -Waddress Date: Tue, 17 May 2022 12:44:26 +0000 [thread overview] Message-ID: <bug-105628-4-jWZ3AqeXX8@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-105628-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105628 --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- The warning is correct but it should not be done. Simpele testcase: struct s{ int f; }; int g(struct s t){ return (t.f?&t.f : 0)? 1 : 0; } The problem is gcc did some optimizations before the warning and pushed the implicit != 0 into each arm of the ?; operator
