From: "law at redhat dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/47679] [4.9/5/6 Regression] Strange uninitialized warning after SRA Date: Sun, 20 Sep 2015 06:16:00 -0000 [thread overview] Message-ID: <bug-47679-4-jaD3qpVPZM@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-47679-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47679 --- Comment #30 from Jeffrey A. Law <law at redhat dot com> --- AFACT the testcase in c#16 is bogus. If i is never equal to k, then opt is never assigned any value. It's then used in the conditional outside the loop. That's how it looks at the source level and that's also what it looks like in the dom2 dump.
