AVX2, FMA, TSX in Haswell

[bronxzv]

Out of curiosity, what software do you develop?

the most optimized code I work on in the core rendering engine of this project : http://www.inartis.com/

and do you regularly compile on every Intel release or just on the tocks?

I regularly compile with the latest version of the Intel compiler but I have only 3 distinct code paths at the moment: SSE2, AVX, AVX2

the final AVX2 path isn't released yet, I have done some tests on pre-production HSW, I still want to do more tuning on a retail CPU before to roll it out
