From: "simon at pushface dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug ada/66162] Bug box compiling Ada.Finalization with -gnatc Date: Sun, 17 May 2015 10:39:00 -0000 [thread overview] Message-ID: <bug-66162-4-Y8EVDX3wrk@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-66162-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66162 --- Comment #2 from simon at pushface dot org --- (In reply to Eric Botcazou from comment #1) > Why on Earth are you doing this? No plan to look into it. Because I agree with Randy Brukardt in https://groups.google.com/d/msg/comp.lang.ada/ECJm5qlxZKA/RKXuEQWN4NYJ that “[n]ot having bounded containers is pretty much like not having arrays”. It’s quite possible to build the Ada 2012 Bounded Vectors & Hashed Maps (& presumably other bounded containers) without finalization provided you’re willing to hack out iterators and references, which is the way I’ve gone up to now; but it seems a real shame not to go the whole hog. People who want to write Ada for MCUs aren’t necessarily in the high-integrity world; some would want to cram as much of the language as possible into the RTS. >From gcc-bugs-return-486469-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Sun May 17 11:49:28 2015 Return-Path: <gcc-bugs-return-486469-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org> Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 14202 invoked by alias); 17 May 2015 11:49:27 -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 14174 invoked by uid 48); 17 May 2015 11:49:21 -0000 From: "hp at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug ipa/66004] [6 Regression]: performance of 26_numerics/random/negative_binomial_distribution/operators/values.cc Date: Sun, 17 May 2015 11:49:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: ipa X-Bugzilla-Version: 6.0 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: hp at gcc dot gnu.org X-Bugzilla-Status: UNCONFIRMED X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: unassigned at gcc dot gnu.org X-Bugzilla-Target-Milestone: 6.0 X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: <bug-66004-4-evg4jtYdtJ@http.gcc.gnu.org/bugzilla/> In-Reply-To: <bug-66004-4@http.gcc.gnu.org/bugzilla/> References: <bug-66004-4@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: 2015-05/txt/msg01309.txt.bz2 Content-length: 754 https://gcc.gnu.org/bugzilla/show_bug.cgi?idf004 --- Comment #4 from Hans-Peter Nilsson <hp at gcc dot gnu.org> --- (In reply to Hans-Peter Nilsson from comment #3) > Something supposedly very good happened recently, because: > r223225 18369501023 > > I'll just have to find out what caused that 50% cut!

I misobserved the "nearby" test-case 26_numerics/random/poisson_distribution/operators/values.cc probably because there was a test-run still in progress. Still, that similar test-case indeed seems to have lower initialization numbers. Lesson learned: always double-check your end-point observations before bisecting.
