Please keep in mind that Intel cannot comment on products that are not yet released.
Intel can only comment products that are already released, this particular product is to be released beginning of 2nd quarter of 2012. I would suggest keeping an eye at the following website until the product is released:
Thank for your answer..
If I refer to last version compiler GNU 4.7 ,I observe new flag to Ivy and Haswell
Origin link: http://gcc.gnu.org/gcc-4.7/changes.html
Support for new Intel processor codename IvyBridge with RDRND, FSGSBASE and F16C is available through -march=core-avx-i.
Support for the new Intel processor codename Haswell with AVX2, FMA, BMI, BMI2, LZCNT is available through -march=core-avx2.
Proving that product datasheet already provided long time ago to Gnu is an public community I think.....
Is very strange we have option flag compiler before or without the product datasheet..
Also my secondary question is on Sandy bridge that is an product current.
