From: "pinskia at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/111972] [14 regression] missed vectorzation for bool a = j != 1; j = (long int)a; Date: Fri, 27 Oct 2023 03:48:12 +0000 [thread overview] Message-ID: <bug-111972-4-f12edq4QjT@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-111972-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111972 Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- See Also| |https://gcc.gnu.org/bugzill | |a/show_bug.cgi?id=112104 --- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- First off does this even make sense to vectorize but rather do some kind of scalar reduction with respect to j = j^1 here . Filed PR 112104 for that. Basically vectorizing this loop is a waste compared to that.
