Date: Mon, 12 Sep 2022 07:20:48 +0000 (GMT) [thread overview] Message-ID: <20220912072048.CBC863850235@sourceware.org> (raw) https://gcc.gnu.org/g:bed01725c1c6a7a463a9b42082ef91a5406588ec commit bed01725c1c6a7a463a9b42082ef91a5406588ec Author: liushuyu <liushuyu011@gmail.com> Date: Mon Sep 5 17:56:03 2022 -0600 backend: correctly formulate the exit condition ... ... previously the exit condition was treated the same as the loop condition (which is the inverse condition of the exit condition). Now this is corrected.
