From: "rguenth at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/98602] Failure to optimise vector “x > -100 ? x : -100” to MAX_EXPR Date: Fri, 08 Jan 2021 13:48:22 +0000 [thread overview] Message-ID: <bug-98602-4-VdzKj8co4C@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-98602-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98602 Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Ever confirmed|0 |1 Last reconfirmed| |2021-01-08 --- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- Guess we miss folders for this since it is represented as VEC_COND_EXPR from the start (the testcase only builds with the C++ frontend) and scalar MIN/MAX are usually detected by phiopt. Ah, fold_cond_expr_with_comparison doesn't handle adjusted constants: return <retval> = VEC_COND_EXPR < x >= { -99, -99, -99, -99 } , x , { -100, -100, -100, -100 } > ;
