"incorrectly?" .. .. it's not clear to me that changing the test to require symbol alias isn't still a regression … (I'd like to understand that the code-gen is equivalent). >From gcc-bugs-return-478757-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Fri Feb 27 15:31:54 2015 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 69894 invoked by alias); 27 Feb 2015 15:31:54 -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 69853 invoked by uid 48); 27 Feb 2015 15:31:50 -0000 From: "aldyh at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug rtl-optimization/65235] [4.8/4.9/5 Regression] Simplifying vec_select of vec_concat miscompiles when first element of vec_concat is const_int Date: Fri, 27 Feb 2015 15:58:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: rtl-optimization X-Bugzilla-Version: 5.0 X-Bugzilla-Keywords: wrong-code X-Bugzilla-Severity: normal X-Bugzilla-Who: aldyh at gcc dot gnu.org X-Bugzilla-Status: UNCONFIRMED X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: ktkachov at gcc dot gnu.org X-Bugzilla-Target-Milestone: 4.8.5 X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: cc 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: 2015-02/txt/msg03089.txt.bz2 Content-length: 603 https://gcc.gnu.org/bugzilla/show_bug.cgi?ide235 Aldy Hernandez changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |aldyh at gcc dot gnu.org --- Comment #1 from Aldy Hernandez --- Hi. The known to work field is empty. Is this a regression? I can't reproduce on a cross build to --targetªrch64-linux by running cc1. What options causes this to fail? Could you post a preprocessed file for the test?
