Actually, for a function that returns a reference, we may also want to warn if we detect that it is returning NULL. And a function returning a pointer could be marked returns_nonnull. In both cases we would be introducing a new warning, more confusing than a duplicate. But there are probably small variations on this idea that would work. >From gcc-bugs-return-446318-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Fri Mar 14 18:04:43 2014 Return-Path: <gcc-bugs-return-446318-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org> Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 32714 invoked by alias); 14 Mar 2014 18:04:43 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: <gcc-bugs.gcc.gnu.org> List-Archive: <http://gcc.gnu.org/ml/gcc-bugs/> List-Post: <mailto:gcc-bugs@gcc.gnu.org> List-Help: <mailto:gcc-bugs-help@gcc.gnu.org> Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 32657 invoked by uid 48); 14 Mar 2014 18:04:39 -0000 From: "mpolacek at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug middle-end/60484] [4.7/4.8/4.9 Regression] -fdump-rtl-expand and attribute optimize gives incorrect dump file path Date: Fri, 14 Mar 2014 18:04:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: middle-end X-Bugzilla-Version: 4.8.2 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: mpolacek at gcc dot gnu.org X-Bugzilla-Status: RESOLVED X-Bugzilla-Priority: P2 X-Bugzilla-Assigned-To: mpolacek at gcc dot gnu.org X-Bugzilla-Target-Milestone: 4.7.4 X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: bug_status resolution Message-ID: <bug-60484-4-avWERhbjlU@http.gcc.gnu.org/bugzilla/> In-Reply-To: <bug-60484-4@http.gcc.gnu.org/bugzilla/> References: <bug-60484-4@http.gcc.gnu.org/bugzilla/> Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 7bit X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2014-03/txt/msg01187.txt.bz2 Content-length: 427 http://gcc.gnu.org/bugzilla/show_bug.cgi?id`484 Marek Polacek <mpolacek at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |RESOLVED Resolution|--- |FIXED --- Comment #7 from Marek Polacek <mpolacek at gcc dot gnu.org> --- Fixed.
