From mboxrd@z Thu Jan 1 00:00:00 1970 From: Waldemar Brodkorb Date: Mon, 27 Feb 2017 07:07:25 +0100 Subject: [Buildroot] [PATCH] vlc: workaround microblaze gcc internal compiler error Message-ID: <20170227060725.GA27933@waldemar-brodkorb.de> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Override gcc optimization flags with -O0. The workaround is not required for gcc6 anymore, but gcc6 is disabled for microblaze, because it breaks startup of the system somehow. So the bug is not reported upstream.
