Can you provide a backtrace of the error? In the build directory, run the executable "gcc/cc1" on a test source file (like the empty main program that libgcc configure tries to compile), under the debugger: "lldb -- ./gcc/cc1 test.c" The debugger starts, then you type "r" (without quotes) and enter. It will = stop at the point of failure, then you type "bt" and enter again. Paste here the result of that last command. This will help understand where things are goi= ng wrong. >>From gcc-bugs-return-468088-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Sat Nov 22 17:30:18 2014 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 29994 invoked by alias); 22 Nov 2014 17:30:18 -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 29962 invoked by uid 48); 22 Nov 2014 17:30:14 -0000 From: "hjl.tools at gmail dot com" To: gcc-bugs@gcc.gnu.org Subject: [Bug middle-end/64028] New: [5 Regression] r211599 caused many vectorizer test failures with -fPIC Date: Sat, 22 Nov 2014 17:30:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: new X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: middle-end X-Bugzilla-Version: 5.0 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: hjl.tools 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: bug_id short_desc product version bug_status bug_severity priority component assigned_to reporter cc Message-ID: 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: 2014-11/txt/msg02560.txt.bz2 Content-length: 775 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64028 Bug ID: 64028 Summary: [5 Regression] r211599 caused many vectorizer test failures with -fPIC Product: gcc Version: 5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: middle-end Assignee: unassigned at gcc dot gnu.org Reporter: hjl.tools at gmail dot com CC: hubicka at ucw dot cz On Linux/ia32, r211599 caused many vectorizer test failures with -fPIC, like: FAIL: gcc.dg/vect/vect-7.c scan-tree-dump-times vect "Vectorizing an unaligned a ccess" 0 FAIL: gcc.dg/vect/vect-7.c -flto -ffat-lto-objects scan-tree-dump-times vect "V ectorizing an unaligned access" 0
