Yeah, I still think the '=' is preferable. I think it lets one know exactly where to insert a cast. >From gcc-bugs-return-451489-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Tue May 13 15:51:17 2014 Return-Path: <gcc-bugs-return-451489-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org> Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 8848 invoked by alias); 13 May 2014 15:51:17 -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 8178 invoked by uid 48); 13 May 2014 15:51:10 -0000 From: "tony.theodore at gmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug lto/60981] lto-plugin configuration doesn't test for -static-libgcc (OSX gcc -> clang) Date: Tue, 13 May 2014 15:51:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: lto X-Bugzilla-Version: 4.9.0 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: tony.theodore at gmail dot com X-Bugzilla-Status: UNCONFIRMED 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: <bug-60981-4-KGmKFtYHkP@http.gcc.gnu.org/bugzilla/> In-Reply-To: <bug-60981-4@http.gcc.gnu.org/bugzilla/> References: <bug-60981-4@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: 2014-05/txt/msg01181.txt.bz2 Content-length: 1574 https://gcc.gnu.org/bugzilla/show_bug.cgi?id`981 --- Comment #6 from Tony Theodore <tony.theodore at gmail dot com> --- (In reply to ro@CeBiTec.Uni-Bielefeld.DE from comment #4) > > --- Comment #3 from Tony Theodore <tony.theodore at gmail dot com> --- > > I'm building a cross compiler with: > > It would have helped enormously if you'd stated so in the first place.

No idea why they changed this in 10.9. Up till LLVM 3.3 there was a gcc plugin called DragonEgg which used gcc as a front-end and LLVM as the back-end. Now "gcc" is basically an alias for the clang front-end. > Your proposed patch has two problems, unfortunately: > > * Don't check for $GCC.

I can confirm that this works with all three mingw targets (after installing autoconf 2.64) - thank you very much! Cheers, Tony
