I guess I missed some entry point within the new scheduler code when fixing the previous PR. >=20 > BTW, why > if (sched_pressure !=3D SCHED_PRESSURE_NONE) > free_global_sched_pressure_data (); > when free_global_sched_pressure_data () contains the same guard and thus > could be called unconditionally? Pilot error while being over cautious, I will simplify that too. >>From gcc-bugs-return-444182-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Wed Feb 19 09:35:21 2014 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 29872 invoked by alias); 19 Feb 2014 09:35:21 -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 29197 invoked by uid 48); 19 Feb 2014 09:35:14 -0000 From: "manu at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug c/59193] Unused postfix operator temporaries Date: Wed, 19 Feb 2014 09:35:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: c X-Bugzilla-Version: unknown X-Bugzilla-Keywords: X-Bugzilla-Severity: minor X-Bugzilla-Who: manu at gcc dot gnu.org X-Bugzilla-Status: REOPENED 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: cc 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: 2014-02/txt/msg01939.txt.bz2 Content-length: 1097 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D59193 Manuel L=C3=B3pez-Ib=C3=A1=C3=B1ez changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |manu at gcc dot gnu.org --- Comment #5 from Manuel L=C3=B3pez-Ib=C3=A1=C3=B1ez --- (In reply to Max TenEyck Woodbury from comment #4) > Since there are hundreds, if not thousands of instances of this defect in= the > GCC code and there is no urgency in correcting these defects, this bug wi= ll > only > get resolved slowly.

If so, please start the copyright assignment process: http://gcc.gnu.org/contribute.html#legal Then, to get your feet wet, it would be better to start with some uncontroversial bugs like: PR25801, or PR55080, or PR57622 or PR52347. I have a long list of easy hacks that would help a lot GCC and its users. >>From gcc-bugs-return-444181-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Wed Feb 19 09:35:16 2014 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 29234 invoked by alias); 19 Feb 2014 09:35:15 -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 29170 invoked by uid 48); 19 Feb 2014 09:35:12 -0000 From: "jakub at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/60267] ICE in c_pp_lookup_pragma, at c-family/c-pragma.c:1232; ICE in tsubst_copy, at cp/pt.c:12887 Date: Wed, 19 Feb 2014 09:35:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: c++ X-Bugzilla-Version: 4.9.0 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: jakub at gcc dot gnu.org X-Bugzilla-Status: ASSIGNED X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: jakub at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: bug_status cf_reconfirmed_on assigned_to everconfirmed attachments.created 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: 2014-02/txt/msg01938.txt.bz2 Content-length: 784 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60267 Jakub Jelinek changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |ASSIGNED Last reconfirmed| |2014-02-19 Assignee|unassigned at gcc dot gnu.org |jakub at gcc dot gnu.org Ever confirmed|0 |1 --- Comment #6 from Jakub Jelinek --- Created attachment 32168 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32168&action=edit gcc49-pr60267-2.patch Untested fix for the tsubst ICE.
