From: "rguenth at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug middle-end/104800] reodering of potentially trapping operations and volatile stores Date: Wed, 09 Mar 2022 07:29:18 +0000 [thread overview] Message-ID: <bug-104800-4-7tc05UUbUK@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-104800-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104800 --- Comment #10 from Richard Biener <rguenth at gcc dot gnu.org> --- Btw, with -ftrapv it would mean we cannot re-order any signed arithmetic with respect to volatile accesses unless we can prove it does not invoke (undefined, but -ftrapv makes it implementation defined) signed overflow.
