Do any of the Intel GPUs support ExtendedDoublesShaderInstructions under Direct3D?

To clarify, this is a new feature exposed through DirectX 11.1 runtime but available at feature level 11_0 if supported. This new feature exposes double precision division and FMA instructions. I believe Nvidia supports this in Fermi and Kepler cards. Any idea if Intel Ivy Bridge and Haswell GPUs support this?

Hello Rahul,

Both 3rd and 4th Generation Core parts (codenamed IvyBridge and Haswell) will expose ExtendedDoublesShaderInstructions.
