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<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CM OV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Features2=0x298e3ff<SSE3,PCLMULQDQ,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,CX16 ,xTPR,PDCM,SSE4.1,SSE4.2,POPCNT,AESNI> 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/
