CPU dispatch

How to manually target 2nd and 3rd generation Intel® Core™ processors with support for Intel® AVX

Manual cpu dispatch may be used to write code that will be executed only on Intel processors with support for Intel® Advanced Vector Extensions, such as 2nd generation Intel® Core™ processors (formerly code named “Sandy Bridge”), 3rd generation Intel® Core™ processors (formerly code named "Ivy Bridge") or future processors with support for Intel Advanced Vector Extensions 2..
