The madd/sub instructionswere one of the new killer features I was waiting for, but now they are gone from the java intrinsics guide(still present in april's release)andrefered to as an extension to AVX in thepdf. Was this feature cut from the first iteration of avx cpus or will it just have a separate cpuid flag?

Hi,

Here is a response from our engineering team: FMA are not part of the Sandy Bridge processor. They will be present in a future processor and will have a separate feature flag.
