You = just need to figure out what C++ code you want to generate (options.c, options.h) and how it will interact with the rest of GCC. I will suggest that you actu= ally prototype your changes directly hacking options.c and options.h, then you modify the awk scripts to generate that code. Modifying the scripts is not = that complex, just printing the right things at the right place (probably our awk scripts can be very much cleaned up and optimized but it hasn't been an iss= ue so far). >>From gcc-bugs-return-495348-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Fri Aug 21 13:12:20 2015 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 24194 invoked by alias); 21 Aug 2015 13:12:19 -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 24165 invoked by uid 48); 21 Aug 2015 13:12:16 -0000 From: "rguenth at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/67306] Patterns ICEs when moved using "simplify and match" Date: Fri, 21 Aug 2015 13:12:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: tree-optimization X-Bugzilla-Version: unknown X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: rguenth at gcc dot gnu.org X-Bugzilla-Status: ASSIGNED X-Bugzilla-Resolution: X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: rguenth at gcc dot gnu.org X-Bugzilla-Target-Milestone: --- X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: bug_status cf_reconfirmed_on assigned_to everconfirmed 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: 2015-08/txt/msg01490.txt.bz2 Content-length: 579 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67306 Richard Biener changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |ASSIGNED Last reconfirmed| |2015-08-21 Assignee|unassigned at gcc dot gnu.org |rguenth at gcc dot gnu.org Ever confirmed|0 |1 --- Comment #1 from Richard Biener --- Ah, indeed.
