However this may not really be important. >>From gcc-bugs-return-420466-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Wed Apr 17 12:34:43 2013 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 27488 invoked by alias); 17 Apr 2013 12:34:43 -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 27443 invoked by uid 48); 17 Apr 2013 12:34:40 -0000 From: "vincent-gcc at vinc17 dot net" To: gcc-bugs@gcc.gnu.org Subject: [Bug middle-end/36296] bogus uninitialized warning (loop representation, VRP missed-optimization) Date: Wed, 17 Apr 2013 12:34:00 -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-Keywords: diagnostic X-Bugzilla-Severity: normal X-Bugzilla-Who: vincent-gcc at vinc17 dot net X-Bugzilla-Status: NEW X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 X-SW-Source: 2013-04/txt/msg01611.txt.bz2 Content-length: 351 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D36296 --- Comment #24 from Vincent Lef=C3=A8vre 2= 013-04-17 12:34:40 UTC --- BTW, since with the latest GCC versions (such as Debian's GCC 4.7.2), the warning is no longer issued with -Wno-maybe-uninitialized, perhaps the bug severity could be lowered to "enhancement". >>From gcc-bugs-return-420467-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Wed Apr 17 13:04:46 2013 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 12043 invoked by alias); 17 Apr 2013 13:04:46 -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 12002 invoked by uid 48); 17 Apr 2013 13:04:43 -0000 From: "manu at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug web/45688] Typo in __attribute__((version-id)) docs Date: Wed, 17 Apr 2013 13:04:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: web X-Bugzilla-Keywords: documentation X-Bugzilla-Severity: trivial X-Bugzilla-Who: manu at gcc dot gnu.org X-Bugzilla-Status: RESOLVED X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Changed-Fields: Status CC Resolution Message-ID: In-Reply-To: References: X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 X-SW-Source: 2013-04/txt/msg01612.txt.bz2 Content-length: 573 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D45688 Manuel L=C3=B3pez-Ib=C3=A1=C3=B1ez changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED CC| |manu at gcc dot gnu.org Resolution| |FIXED --- Comment #3 from Manuel L=C3=B3pez-Ib=C3=A1=C3=B1ez 2013-04-17 13:04:42 UTC --- So FIXED.
