There is no common convention in the GCC documentation and other \nparts of the manual do deliberately diverge from alphabetization in \nplaces. There's a perpetual tension between putting the most \ncommonly-needed information first vs grouping things by related concepts \nvs alphabetize vs the tendency of people to insert new items at random \nplaces in an existing list regardless of how it's previously been \norganized. :-(\n\nAlphabetical lists are useful when you already know the name of the \nthing you are searching for, but almost everybody reads the \ndocumentation in a web browser or PDF viewer with a search feature \nnowadays so you can find the term no matter how the list is sorted. So \nI'd say we shouldn't alphabetize as a matter of policy if there is some \nother organization that makes sense.\n\nIn this case, the section is already broken into multiple sublists by \ntopic, most of the sublists are fairly short, and where there's some \ndiscernible sort order within the sublists, it seems to be grouping \nrelated things together rather than alphabetical. So I wouldn't insist \non alphabetizing this particular sublist either.\n\n-Sandra","headers":{"Return-Path":"","X-Original-To":"incoming@patchwork.ozlabs.org","Delivered-To":["patchwork-incoming@bilbo.ozlabs.org","mailing list gcc-patches@gcc.gnu.org"],"Authentication-Results":["ozlabs.org;\n\tspf=pass (mailfrom) smtp.mailfrom=gcc.gnu.org\n\t(client-ip=209.132.180.131; helo=sourceware.org;\n\tenvelope-from=gcc-patches-return-463068-incoming=patchwork.ozlabs.org@gcc.gnu.org;\n\treceiver=)","ozlabs.org; dkim=pass (1024-bit key;\n\tunprotected) header.d=gcc.gnu.org header.i=@gcc.gnu.org\n\theader.b=\"xRUeZ+Lt\"; dkim-atps=neutral","sourceware.org; auth=none"],"Received":["from sourceware.org (server1.sourceware.org [209.132.180.131])\n\t(using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256\n\tbits)) (No client certificate requested)\n\tby ozlabs.org (Postfix) with ESMTPS id 3y2Pwq2V9Dz9t4b\n\tfor ;\n\tThu, 28 Sep 2017 03:30:35 +1000 (AEST)","(qmail 122340 invoked by alias); 27 Sep 2017 17:30:25 -0000","(qmail 105120 invoked by uid 89); 27 Sep 2017 17:30:19 -0000","from relay1.mentorg.com (HELO relay1.mentorg.com) (192.94.38.131)\n\tby sourceware.org (qpsmtpd/0.93/v0.84-503-g423c35a) with\n\tESMTP; Wed, 27 Sep 2017 17:30:17 +0000","from svr-orw-mbx-03.mgc.mentorg.com ([147.34.90.203])\tby\n\trelay1.mentorg.com with esmtps\n\t(TLSv1.2:ECDHE-RSA-AES256-SHA384:256)\tid 1dxGA1-0006Ni-U2\n\tfrom Sandra_Loosemore@mentor.com ; Wed, 27 Sep 2017 10:30:13 -0700","from [127.0.0.1] (147.34.91.1) by svr-orw-mbx-03.mgc.mentorg.com\n\t(147.34.90.203) with Microsoft SMTP Server (TLS) id\n\t15.0.1263.5; Wed, 27 Sep 2017 10:30:10 -0700"],"DomainKey-Signature":"a=rsa-sha1; c=nofws; d=gcc.gnu.org; h=list-id\n\t:list-unsubscribe:list-archive:list-post:list-help:sender\n\t:subject:to:references:cc:from:message-id:date:mime-version\n\t:in-reply-to:content-type:content-transfer-encoding; q=dns; s=\n\tdefault; b=o+z/5ZTNFPLK8tXzPohS8hKRFroOygWSq4G4RJ7fUgzgXqWBLkIEF\n\t1nJtfuq+lyGTsO24aC521zLvYZn4yq6EQLYoTosgOnbrs9M1HyZ72P3a4FZLwFJK\n\t9W29kc7zXE5L53iicixeRxWsI9Jqz578evidSYXeGFHScuU5RMB6Ko=","DKIM-Signature":"v=1; a=rsa-sha1; c=relaxed; d=gcc.gnu.org; h=list-id\n\t:list-unsubscribe:list-archive:list-post:list-help:sender\n\t:subject:to:references:cc:from:message-id:date:mime-version\n\t:in-reply-to:content-type:content-transfer-encoding; s=default;\n\tbh=D/BW3CrkU/4NvX4JgBEEPNx98BM=; b=xRUeZ+LtFND/jz1pMB+lA7Qj149N\n\tRx1K+bE6IJG+ccj7niOct/Y2fehcTeo9ZZwQvTBnEMFgWYm5MtjHifIwcDghse5v\n\tXEunvwKrxXKUOt5MzziwMsX4PQY//gFVyDInRYXpuj1uICHSmaIeLsLLaZBGQtvY\n\tn5+gwng3Xzsk7iA=","Mailing-List":"contact gcc-patches-help@gcc.gnu.org; run by ezmlm","Precedence":"bulk","List-Id":"","List-Unsubscribe":"","List-Archive":"","List-Post":"","List-Help":"","Sender":"gcc-patches-owner@gcc.gnu.org","X-Virus-Found":"No","X-Spam-SWARE-Status":"No, score=-24.6 required=5.0 tests=AWL, BAYES_00,\n\tGIT_PATCH_0, GIT_PATCH_1, GIT_PATCH_2, GIT_PATCH_3,\n\tRCVD_IN_DNSWL_NONE,\n\tSPF_PASS autolearn=ham version=3.3.2 spammy=concepts,\n\tH*UA:38.0, H*u:38.0, perpetual","X-HELO":"relay1.mentorg.com","Subject":"Re: [PATCH 4/5] New target check: vect_nopeel - v2","To":"Rainer Orth ,\n\tAndreas Krebbel\t","References":"<20170926113950.5472-1-krebbel@linux.vnet.ibm.com>\n\t<20170926113950.5472-5-krebbel@linux.vnet.ibm.com>\n\t<232952d2-9e6f-0c35-43e6-e46164d96346@linux.vnet.ibm.com>\n\t\n\t\n\t\n\t<4986ee4a-16b1-2a43-061f-e7663ccc14bb@linux.vnet.ibm.com>\n\t","CC":"","From":"Sandra Loosemore ","Message-ID":"<59CBE021.5000208@codesourcery.com>","Date":"Wed, 27 Sep 2017 11:30:09 -0600","User-Agent":"Mozilla/5.0 (X11; Linux x86_64;\n\trv:38.0) Gecko/20100101 Thunderbird/38.5.1","MIME-Version":"1.0","In-Reply-To":"","Content-Type":"text/plain; charset=\"windows-1252\"; format=flowed","Content-Transfer-Encoding":"7bit","X-ClientProxiedBy":"svr-orw-mbx-04.mgc.mentorg.com (147.34.90.204) To\n\tsvr-orw-mbx-03.mgc.mentorg.com (147.34.90.203)"}},{"id":1776979,"web_url":"http://patchwork.ozlabs.org/comment/1776979/","msgid":"<4d32254a-ac45-3cd8-f4df-7528873e12f1@linux.vnet.ibm.com>","list_archive_url":null,"date":"2017-09-28T11:54:52","subject":"Re: [PATCH 4/5] New target check: vect_nopeel - v2","submitter":{"id":4421,"url":"http://patchwork.ozlabs.org/api/people/4421/","name":"Andreas Krebbel","email":"krebbel@linux.vnet.ibm.com"},"content":"On 09/26/2017 06:49 PM, Richard Sandiford wrote:\n> Andreas Krebbel writes:\n...\n> Sorry for the bikeshedding, but how about having a positive test\n> like vect_can_peel instead? ! vect_no... can be hard to read in\n> complex conditions.
