I had already asked this question once without getting an answer, but I
think it should have an answer before this change can go in: Is AMD indeed
planning on implementing FMA in a way Intel planned to originally, but
changed from since? If so, what are the plans between the two
implementations to avoid future collision in the opcode space?
