D3D: ExtendedDoublesShaderInstructions on which cards?

[codedivine]

UPDATE: The title was mangled. I meant ExtendedDoublesShaderInstructions in D3D.

I am wondering if anyone knows which cards from AMD, Nvidia and Intel support ExtendedDoublesShaderInstructions capability in DirectX?

My understanding is that it should work on any Fermi and Kepler cards with double-precision support and on AMD side, should work on 58xx, 69xx, Trinity's GPU as well as GCN cards. Not very sure about Intel. Is this correct?

To answer my own question:

a) Intel folks confirmed extended double instructions supported on Ivy Bridge ans Haswell
b) I confirmed from testing myself that GCN cards also support extended double instructions
c) Some Nvidia documentation seem to suggest they should be supported on Fermi and Kepler cards.
