Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit X-IsSubscribed: yes Mailing-List: contact gcc-help-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Archive: List-Post: List-Help: Sender: gcc-help-owner@gcc.gnu.org X-SW-Source: 2006-06/txt/msg00069.txt.bz2 Hi, I was wondering what march to specify in my cflags for the Intel Core Duo L2400 processor. The gentoo-wiki says that the safe cflag is prescott, but I figured I would ask here to find the optimal for this processor, or if the prescott is truly the safest/optimal. Here is my /proc/cpuinfo for it: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 14 model name : Genuine Intel(R) CPU L2400 @ 1.66GHz stepping : 8 cpu MHz : 1662.571 cache size : 2048 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx pni monitor vmx est tm2 xtpr bogomips : 3331.72 processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 14 model name : Genuine Intel(R) CPU L2400 @ 1.66GHz stepping : 8 cpu MHz : 1662.571 cache size : 2048 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx pni monitor vmx est tm2 xtpr bogomips : 3325.15 - George
