X-BeenThere: freebsd-stable@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Production branch of FreeBSD source code List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 30 May 2012 14:15:49 -0000 Hi, Today I want to compile the latest www/chromium, and I found that I encountered some SSSE3 problems, with either gcc46/clang, and I found that this new version requires (S)SSE3 support. My CPU is a Intel i5 M 520, which suppose to support these. But when I'm checking the CPU features, I see: CPU: Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz (2394.02-MHz K8-class CPU) Origin = "GenuineIntel" Id = 0x20652 Family = 6 Model = 25 Stepping = 2 Features=0xbfebfbff Features2=0x298e3ff What? Different features on different cores? Is it my CPU's problem or FreeBSD's problem? -- Zhihao Yuan, nickname lichray The best way to predict the future is to invent it. ___________________________________________________ 4BSD -- http://4bsd.biz/
