From: "jakub at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug other/79469] Feature request: provide `__builtin_assume` builtin function to allow more aggressive optimizations and to match clang Date: Wed, 26 Oct 2022 19:52:04 +0000 [thread overview] Message-ID: <bug-79469-4-RAkQmShiOw@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-79469-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79469 Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Just use the attribute, I'd prefer not to add the builtin, especially when clang makes it pretty much useless (as it warns about side-effects in the arg, doesn't evaluate them and ignores it completely in that case).
