Or\r\n> are the ARC patches too difficult to backport?\r\n\r\nWell not now definitely. The point is:\r\n a) ARC port is not yet merged upstream\r\n b) Our patches are on top of pretty much up-to-date master branch,\r\n    which means they alone won't apply on top of the most recent release\r\n\r\n> \r\n> \r\n> > \r\n> > I'd like to see how we ramp-up with glibc toolchain for ARC.\r\n> > That said once the patch is applied would be good to add\r\n> > a corresponding config for autobuilder.\r\n> \r\n>  You can actually do that yourself by adding a config to\r\n> support/config-fragments/autobuild and updating toolchain-configs.csv\r\n> in that directory. Something like br-arc-full-internal.config but then with glibc.\r\n\r\nSure, will do once glibc for ARC is supported in BR.\r\n\r\n-Alexey","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","buildroot@lists.busybox.net"],"Delivered-To":["patchwork-incoming@bilbo.ozlabs.org","buildroot@osuosl.org"],"Authentication-Results":"ozlabs.org;\n\tspf=pass (mailfrom) smtp.mailfrom=busybox.net\n\t(client-ip=140.211.166.138; helo=whitealder.osuosl.org;\n\tenvelope-from=buildroot-bounces@busybox.net;\n\treceiver=)","Received":["from whitealder.osuosl.org (smtp1.osuosl.org [140.211.166.138])\n\t(using TLSv1.2 with cipher AECDH-AES256-SHA (256/256 bits))\n\t(No client certificate requested)\n\tby ozlabs.org (Postfix) with ESMTPS id 3y7Qtk6lfHz9t2f\n\tfor ;\n\tFri, 6 Oct 2017 08:31:10 +1100 (AEDT)","from localhost (localhost [127.0.0.1])\n\tby whitealder.osuosl.org (Postfix) with ESMTP id D833789034;\n\tThu, 5 Oct 2017 21:31:08 +0000 (UTC)","from whitealder.osuosl.org ([127.0.0.1])\n\tby localhost (.osuosl.org [127.0.0.1]) (amavisd-new, port 10024)\n\twith ESMTP id vqKcCjnJXHko; Thu, 5 Oct 2017 21:31:07 +0000 (UTC)","from ash.osuosl.org (ash.osuosl.org [140.211.166.34])\n\tby whitealder.osuosl.org (Postfix) with ESMTP id D377F89155;\n\tThu, 5 Oct 2017 21:31:07 +0000 (UTC)","from whitealder.osuosl.org (smtp1.osuosl.org [140.211.166.138])\n\tby ash.osuosl.org (Postfix) with ESMTP id EF6EE1C097A\n\tfor ;\n\tThu, 5 Oct 2017 21:31:06 +0000 (UTC)","from localhost (localhost [127.0.0.1])\n\tby whitealder.osuosl.org (Postfix) with ESMTP id EA97889155\n\tfor ;\n\tThu, 5 Oct 2017 21:31:06 +0000 (UTC)","from whitealder.osuosl.org ([127.0.0.1])\n\tby localhost (.osuosl.org [127.0.0.1]) (amavisd-new, port 10024)\n\twith ESMTP id AAfsktkd1MjI for ;\n\tThu, 5 Oct 2017 21:31:06 +0000 (UTC)","from smtprelay.synopsys.com (smtprelay2.synopsys.com\n\t[198.182.60.111])\n\tby whitealder.osuosl.org (Postfix) with ESMTPS id E1ADD89034\n\tfor ; Thu, 5 Oct 2017 21:31:05 +0000 (UTC)","from mailhost.synopsys.com (mailhost1.synopsys.com [10.12.238.239])\n\tby smtprelay.synopsys.com (Postfix) with ESMTP id A41B710C0C35;\n\tThu, 5 Oct 2017 14:31:04 -0700 (PDT)","from mailhost.synopsys.com (localhost [127.0.0.1])\n\tby mailhost.synopsys.com (Postfix) with ESMTP id 8C7F2C2D;\n\tThu, 5 Oct 2017 14:31:04 -0700 (PDT)","from us01wehtc1.internal.synopsys.com\n\t(us01wehtc1-vip.internal.synopsys.com [10.12.239.236])\n\tby mailhost.synopsys.com (Postfix) with ESMTP id 73413BF9;\n\tThu, 5 Oct 2017 14:31:03 -0700 (PDT)","from DE02WEHTCB.internal.synopsys.com (10.225.19.94) by\n\tus01wehtc1.internal.synopsys.com (10.12.239.235) with Microsoft SMTP\n\tServer (TLS) id 14.3.266.1; Thu, 5 Oct 2017 14:30:28 -0700","from DE02WEMBXB.internal.synopsys.com ([fe80::95ce:118a:8321:a099])\n\tby DE02WEHTCB.internal.synopsys.com ([::1]) with mapi id\n\t14.03.0266.001; Thu, 5 Oct 2017 23:30:25 +0200"],"X-Virus-Scanned":["amavisd-new at osuosl.org","amavisd-new at osuosl.org"],"X-Greylist":"domain auto-whitelisted by SQLgrey-1.7.6","From":"Alexey Brodkin ","To":"\"arnout@mind.be\" ","Thread-Topic":"[PATCH 2/2] toolchain: Add glibc support for ARCv2","Thread-Index":"AQHTLabrgaSIsIXUbkGdbWacmqkdNKLKmIIAgAlJ/YCAAeL6AA==","Date":"Thu, 5 Oct 2017 21:30:24 +0000","Message-ID":"<1507239024.31627.18.camel@synopsys.com>","References":"<20170914221446.13647-1-abrodkin@synopsys.com>\n\t<20170914221446.13647-3-abrodkin@synopsys.com>\n\t<1506624636.3713.20.camel@synopsys.com>\n\t","In-Reply-To":"","Accept-Language":"en-US, ru-RU","Content-Language":"en-US","X-MS-Has-Attach":"","X-MS-TNEF-Correlator":"","x-originating-ip":"[10.225.15.124]","Content-ID":"<98B2CF92D17F014899D58A7605C0CB78@internal.synopsys.com>","MIME-Version":"1.0","Cc":"\"Cupertino.Miranda@synopsys.com\" ,\n\t\"thomas.petazzoni@free-electrons.com\"\n\t,\n\t\"Vineet.Gupta1@synopsys.com\" ,\n\t\"Anton.Kolesov@synopsys.com\" ,\n\t\"buildroot@busybox.net\" ","Subject":"Re: [Buildroot] [PATCH 2/2] toolchain: Add glibc support for ARCv2","X-BeenThere":"buildroot@busybox.net","X-Mailman-Version":"2.1.18-1","Precedence":"list","List-Id":"Discussion and development of buildroot ","List-Unsubscribe":",\n\t","List-Archive":"","List-Post":"","List-Help":"","List-Subscribe":",\n\t","Content-Type":"text/plain; charset=\"utf-8\"","Content-Transfer-Encoding":"base64","Errors-To":"buildroot-bounces@busybox.net","Sender":"\"buildroot\" "}}]
