From: "jakub at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/95836] Failure to remove strchr converted to bool with string literal when bit magic would be much more efficient (and sometimes smaller) Date: Tue, 23 Jun 2020 16:43:12 +0000 [thread overview] Message-ID: <bug-95836-4-YaZQT62xgK@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-95836-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95836 --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Well, it does, we can't keep it in the IL in that form because the compiler itself might optimize it away on the assumption that UB doesn't happen.
