I guess this is a change to the spec, after the V1.0, 2012-05 edition that I
have?
Well, I guess this is a mistake in the documentation. The signature says
the result is 32 bit, but the pseudo-code states E[c] = result[63:0] and
E[c] is clearly a 64 bit register.
My tests with the manufacturers simulator show the 64 bit behavior, too.
