From: "glisse at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c/63803] When GCC 4.9.2 compile with option -O2, the target is error. Date: Mon, 10 Nov 2014 11:36:00 -0000 [thread overview] Message-ID: <bug-63803-4-demfVSZbo3@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-63803-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63803 --- Comment #6 from Marc Glisse <glisse at gcc dot gnu.org> --- If dereferencing 0 is ok on your platform, you need at least -fno-delete-null-pointer-checks. I don't know if the isolate pass checks that flag though (it probably should).
