... stack. There are no call-preserved vector registers. (A function with a mix of FP and integer arguments can have more than 8 total register arguments.)
Variadic functions (like printf) always need %al = the number of FP register args.
There are rules for when to pack structs into registers (rdx...

... cases, the type closes over some type constructor F.
Note that this view mixes types and values. The existential proof is one type and one value. The universal proof is an entire family of values indexed by type (or a mapping from types to values).
So the difference between the two types you spec...
