Gentoo使用技巧（29）
技术手册（135）
Warning:&GCC 4.2 and above support -march=native, which automatically detects the optimum settings to use based on your processor. -march=native also detects and applies additional settings beyond -march specific to your CPU, (eg. -msse4). Unless you have a specific reason not to (e.g. distcc cross-compiling), you should probably be using -march=native rather than anything listed below. To find out what -march=native actually picks on the local hardware see&.Contents&[hide]&1&Pentium2&Pentium w/ MMX3&Pentium Pro4&Pentium II5&Celeron (Mendocino), aka Celeron16&Pentium III/ Mobile Celeron7&Celeron (Coppermine)8&Celeron (Willamette)9&Pentium M(Centrino)/Celeron M10&Mobile Pentium 4-M (Northwood)11&Pentium 412&Pentium 4 (Prescott) / Celeron D13&Pentium D 8xx / 9xx14&Xeon w/o EM64T15&Xeon w/EM64T (also Pentium 4 P6xx or Celeron M 5xx)16&Intel Core Solo/Duo, Pentium Dual-Core T20xx/T21xx17&Core 2 Duo/Quad, Xeon 51xx/53xx/54xx/3360, Pentium Dual-Core T23xx+/Exxxx, Celeron Dual-Core18&Core i7 and Core i5, Xeon 55xx19&Atom 230, Atom 330, Atom N-Series[]vendor_id&: GenuineIntel

Note:&You can verify the chip is a Prescott by looking for pni in the flags section of /proc/cpuinfo. This indicates support for SSE3.In 2004, Intel started branding processors with the Prescott core as Intel Celeron D.[]vendor_id&: GenuineIntel

Notes:It has been confirmed by hongjiu. that prescott is the correct microarchitecture to use with this CPU.&The newer (eg. 420) Celeron-M processors are Core Solo based, not Pentium-M based. If your processor's family and model are 6 and 14, then you should use the -march=prescott option.Both the Celeron 4x0 and 220 run fine with Processor family (Pentium M) selected in the kernel.[]vendor_id &: GenuineIntel
