X-BeenThere: openembedded-core@lists.openembedded.org X-Mailman-Version: 2.1.12 Precedence: list List-Id: Patches and discussions about the oe-core layer List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 21 Aug 2014 19:49:06 -0000 Content-Type: text/plain The various cortex chips generally support thumb code, so the armv7at tunings are a better default for them than the plain armv7a tunings. The armv7at tuning allows generation of both arm and thumb code, while armv7a only allows arm code, which is typically significantly bigger. (It may be faster in some cases, but the tradeoffs aren't totally obvious, because smaller code fits in caches better.) Since they all had armv7a-neon as default, change them to armv7at-neon.
