* The special flag for Opteron_G3 is "sse4a"


- The following is the summary of special flag for every cpu model.

Intel:

* Sandy Bridge

XSAVE/XRSTOR, avx

* Westmere

aes

* Nehalem

sse4.2

* Penryn

sse4.1

* Conroe

no sse4.2, sse4.1

AMD:

* Opteron_G1

Opteron_G1 doesn't support VT, pls use 1216 to replace it.

amd-1216-8-1 amd-1216-8-2

* Opteron_G2

no sse4a

* Opteron_G3

sse4a

* Opteron_G4

no Bulldozer in our office, need to bollow it from beaker

sse4.2, xsave, avx
