Hai

Please help me in enbaling the SSE 3 and SSE 4.2 in visual studio 2010 ultimate. I am currently working on a sandy bridge processor based desktopplatform running on win 7 SP1. The AVX option is getting enabled through /arch:AVX command line option, but not SSE options. I just have options of enabling SSE and SSE2, not higher versions. I tried with/QxAVX, /QaxAVX,/arch:SSE, /arch:SSE2...when I tried to compile the code , it is ignoring these options. It is just accepting /arch:AVX. I want the SSE 3.0 and higheroptionsto be enabled in this tool.Do I need to write an intrinsic code for my application to enable these SSE3, SSE4.2instruction set support ?Please help.

Thanks
Rahul

Hi Rahul,

I think this is a double post: http://software.intel.com/en-us/forums/showthread.php?t=84683 . There you can already find an answer.

Thanks,
Alex
