From: "rguenth at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/48571] [4.5/4.6/4.7 Regression] Missed data-dependence for (bogus?) reconstructed array-refs Date: Tue, 12 Apr 2011 13:12:00 -0000 [thread overview] Message-ID: <bug-48571-4-Ifu5PAFTWW@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-48571-4@http.gcc.gnu.org/bugzilla/> http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48571 --- Comment #2 from Richard Guenther <rguenth at gcc dot gnu.org> 2011-04-12 13:11:56 UTC --- Re-constructing array-refs (and thus an index space) is invalid. Which means the C frontend should better change its behavior and not lower all array accesses to pointer arithmetic and dereferences.
