From: "aldyh at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/101938] [12 Regression] Wrong code with -fwrapv since r12-2591-g2e96b5f14e402569 Date: Tue, 17 Aug 2021 08:59:04 +0000 [thread overview] Message-ID: <bug-101938-4-S1eRlGXdrd@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-101938-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101938 --- Comment #4 from Aldy Hernandez <aldyh at gcc dot gnu.org> --- This is actually an oversight in the range-ops code. In flag_wrapv -TYPE_MIN_VALUE = TYPE_MIN_VALUE which is special cased in the ABS folding routine, but not in operator_abs::op1_range(). Thank you for reporting and distilling this Martin.
