From: "pinskia at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/111957] `a ? abs(a) : 0` is not simplified to just abs(a) Date: Tue, 24 Oct 2023 22:37:54 +0000 [thread overview] Message-ID: <bug-111957-4-84LTxRhUCf@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-111957-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111957 --- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- We already have patterns for -a and ~a even: /* X != C1 ? -X : C2 simplifies to -X when -C1 == C2. */ /* X != C1 ? ~X : C2 simplifies to ~X when ~C1 == C2. */ I will add one to handle abs too.
