[Would it help to mark the argument of h() with a "nonnull" attribute?] Side remark 2: I think the test case is not fully right. g()'s call check (x) is invalid if "x" is NULL as check's "x" is neither OPTIONAL nor a POINTER.= In terms of the generated code, I think this shouldn't matter in this case. >>From gcc-bugs-return-468773-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Thu Nov 27 14:20:46 2014 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 15436 invoked by alias); 27 Nov 2014 14:20:46 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 15394 invoked by uid 48); 27 Nov 2014 14:20:42 -0000 From: "manu at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug driver/64094] "No such file or directory" -> "No such file" Date: Thu, 27 Nov 2014 14:20:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: driver X-Bugzilla-Version: unknown X-Bugzilla-Keywords: diagnostic X-Bugzilla-Severity: normal X-Bugzilla-Who: manu at gcc dot gnu.org X-Bugzilla-Status: NEW X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2014-11/txt/msg03245.txt.bz2 Content-length: 1369 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D64094 --- Comment #4 from Manuel L=C3=B3pez-Ib=C3=A1=C3=B1ez --- My preference would be a gnulib/glibc/libiberty function that all GNU utili= ties could use to give more precise error messages (open_strerror(int errnum, int flags)?). Then, perhaps update the Coding Standards to recommend the use of= the function. Then, use it in GCC and binutils for consistency (and to avoid translating the same string for each project). The benefit may seem minor to many people (and I guess all existing GCC devs have things to work on that they consider much more crucial). However, some= body went through all the trouble to report a bug, so I would not want to discou= rage anyone from going ahead and do whatever is needed. Maybe then they will dec= ide to tackle other problems with GCC/binutils (there are plenty to choose from, and help is always welcome). I would like to encourage people to work on GCC, even if, to me, the benefit does not compensate the effort, they may have other priorities. A good exam= ple of this is: https://gcc.gnu.org/ml/gcc/2014-10/msg00104.html where someone proposed a controversial change, but a path forward to a solution was offer= ed. That person followed up and a patch is almost ready to be merged: https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00845.html >>From gcc-bugs-return-468774-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Thu Nov 27 14:22:44 2014 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 17744 invoked by alias); 27 Nov 2014 14:22:43 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 17713 invoked by uid 48); 27 Nov 2014 14:22:38 -0000 From: "rguenth at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/64091] [5 Regression] ICE in update_debug_stmt, at tree-ssa-tail-merge.c:1620 Date: Thu, 27 Nov 2014 14:22:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: tree-optimization X-Bugzilla-Version: 5.0 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: rguenth at gcc dot gnu.org X-Bugzilla-Status: RESOLVED X-Bugzilla-Priority: P1 X-Bugzilla-Assigned-To: rguenth at gcc dot gnu.org X-Bugzilla-Target-Milestone: 5.0 X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: bug_status resolution Message-ID: In-Reply-To: References: 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: 2014-11/txt/msg03246.txt.bz2 Content-length: 428 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64091 Richard Biener changed: What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |RESOLVED Resolution|--- |FIXED --- Comment #5 from Richard Biener --- Fixed.
