From: "joseph at codesourcery dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug middle-end/66127] Division by zero gets folded away Date: Tue, 12 May 2015 16:06:00 -0000 [thread overview] Message-ID: <bug-66127-4-qhClXdL7mg@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-66127-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66127 --- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- Ideally the front-end folding of expressions-of-constants might avoid folding-for-optimization such as this (instead just folding cases where the evaluated operands are actually constants, so not folding anything where 1 / 0 is an evaluated operand).
