From mboxrd@z Thu Jan 1 00:00:00 1970 From: Romain Naour Date: Sat, 8 Dec 2018 20:06:19 +0100 Subject: [Buildroot] [PATCH 2/2] package/gcc: remove arm soft patch In-Reply-To: <20181208190619.9977-1-romain.naour@gmail.com> References: <20181208190619.9977-1-romain.naour@gmail.com> Message-ID: <20181208190619.9977-2-romain.naour@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net The patch refers to [1] which says "Unfortuantely, arm-gcc defaults to generating code for armv5t." Since we always explicitly pass the target CPU for ARM, the default CPU shouldn't matter. As suggested by Arnout [2], a test based on qemu_arm_versatile_defconfig has been done without this patch and there is no regression.
