; ************ DESCRIZIONE SOTTOPROGRAMMA ************
Il seguente sottoprogramma denominato SEQMOD riceve nel registro R0 il numero intero N e
restituisce sempre in R0 l’ennesimo termine S(N) della sequenza definita nel seguente modo:
S(N) = |S(N-1)| – 2 x S(N-2)
con S1 = 1 e S2 = 1 e dove la notazione |SN-1| indica il valore assoluto del numero S(N-1).
Si ipotizza inoltre che S(N) = 0 per N ≤ 0
Nonostante l'utilizzo di altri registri della CPU, il sottoprogramma restituisce
il controllo al programma chiamante senza che tali registri risultino alterati.

agda-stdlib/README/Inspect.agda | DreamLinuxer/popl21-artifact | 5 | 3377 | ------------------------------------------------------------------------
-- The Agda standard library
--
-- Explaining how to use the inspect idiom and elaborating on the way
-- it is implemented in the standard library.
------------------------------------------------------------------------
{-# OPTIONS --without-K --safe #-}
module README.Inspect where
open import Data.Nat.Base
open import Data.Nat.Properties
open import Data.Product
open import Relation.Binary.PropositionalEquality
------------------------------------------------------------------------
-- Using inspect
-- We start with the definition of a (silly) predicate: `Plus m n p` states
-- that `m + n` is equal to `p` in a rather convoluted way. Crucially, it
-- distinguishes two cases: whether `p` is 0 or not.
Plus-eq : (m n p : ℕ) → Set
Plus-eq m n zero = m ≡ 0 × n ≡ 0
Plus-eq m n p@(suc _) = m + n ≡ p
-- A sensible lemma to prove of this predicate is that whenever `p` is literally
-- `m + n` then `Plus m n p` holds. That is to say `∀ m n → Plus m n (m + n)`.
-- To be able to prove `Plus-eq m n (m + n)`, we need `m + n` to have either
-- the shape `zero` or `suc _` so that `Plus-eq` may reduce.
-- We could follow the way `_+_` computes by mimicking the same splitting
-- strategy, thus forcing `m + n` to reduce:
plus-eq-+ : ∀ m n → Plus-eq m n (m + n)
plus-eq-+ zero zero = refl , refl
plus-eq-+ zero (suc n) = refl
plus-eq-+ (suc m) n = refl
-- Or we could attempt to compute `m + n` first and check whether the result
-- is `zero` or `suc p`. By using `with m + n` and naming the result `p`,
-- the goal will become `Plus-eq m n p`. We can further refine this definition
-- by distinguishing two cases like so:
-- plus-eq-with : ∀ m n → Plus-eq m n (m + n)
-- plus-eq-with m n with m + n
-- ... | zero = {!!}
-- ... | suc p = {!!}
-- The problem however is that we have abolutely lost the connection between the
-- computation `m + n` and its result `p`. Which makes the two goals unprovable:
-- 1. `m ≡ 0 × n ≡ 0`, with no assumption whatsoever
-- 2. `m + n ≡ suc p`, with no assumption either
-- By using the `with` construct, we have generated an auxiliary function that
-- looks like this:
-- `plus-eq-with-aux : ∀ m n p → Plus-eq m n p`
-- when we would have wanted a more precise type of the form:
-- `plus-eq-aux : ∀ m n p → m + n ≡ p → Plus-eq m n p`.
-- This is where we can use `inspect`. By using `with f x | inspect f x`,
-- we get both a `y` which is the result of `f x` and a proof that `f x ≡ y`.
-- Splitting on the result of `m + n`, we get two cases:
-- 1. `m ≡ 0 × n ≡ 0` under the assumption that `m + n ≡ zero`
-- 2. `m + n ≡ suc p` under the assumption that `m + n ≡ suc p`
-- The first one can be discharged using lemmas from Data.Nat.Properties and
-- the second one is trivial.
plus-eq-with : ∀ m n → Plus-eq m n (m + n)
plus-eq-with m n with m + n | inspect (m +_) n
... | zero | [ m+n≡0 ] = m+n≡0⇒m≡0 m m+n≡0 , m+n≡0⇒n≡0 m m+n≡0
... | suc p | [ m+n≡1+p ] = m+n≡1+p
------------------------------------------------------------------------
-- Understanding the implementation of inspect
-- So why is it that we have to go through the record type `Reveal_·_is_`
-- and the ̀inspect` function? The fact is: we don't have to if we write
-- our own auxiliary lemma:
plus-eq-aux : ∀ m n → Plus-eq m n (m + n)
plus-eq-aux m n = aux m n (m + n) refl where
aux : ∀ m n p → m + n ≡ p → Plus-eq m n p
aux m n zero m+n≡0 = m+n≡0⇒m≡0 m m+n≡0 , m+n≡0⇒n≡0 m m+n≡0
aux m n (suc p) m+n≡1+p = m+n≡1+p
-- The problem is that when we write ̀with f x | pr`, `with` decides to call `y`
-- the result `f x` and to replace *all* of the occurences of `f x` in the type
-- of `pr` with `y`. That is to say that if we were to write:
-- plus-eq-naïve : ∀ m n → Plus-eq m n (m + n)
-- plus-eq-naïve m n with m + n | refl {x = m + n}
-- ... | p | eq = {!!}
-- then `with` would abstract `m + n` as `p` on *both* sides of the equality
-- proven by `refl` thus giving us the following goal with an extra, useless,
-- assumption:
-- 1. `Plus-eq m n p` under the assumption that `p ≡ p`
-- So how does `inspect` work? The standard library uses a more general version
-- of the following type and function:
record MyReveal_·_is_ (f : ℕ → ℕ) (x y : ℕ) : Set where
constructor [_]
field eq : f x ≡ y
my-inspect : ∀ f n → MyReveal f · n is (f n)
my-inspect f n = [ refl ]
-- Given that `inspect` has the type `∀ f n → Reveal f · n is (f n)`, when we
-- write `with f n | inspect f n`, the only `f n` that can be abstracted in the
-- type of `inspect f n` is the third argument to `Reveal_·_is_`.
-- That is to say that the auxiliary definition generated looks like this:
plus-eq-reveal : ∀ m n → Plus-eq m n (m + n)
plus-eq-reveal m n = aux m n (m + n) (my-inspect (m +_) n) where
aux : ∀ m n p → MyReveal (m +_) · n is p → Plus-eq m n p
aux m n zero [ m+n≡0 ] = m+n≡0⇒m≡0 m m+n≡0 , m+n≡0⇒n≡0 m m+n≡0
aux m n (suc p) [ m+n≡1+p ] = m+n≡1+p
-- At the cost of having to unwrap the constructor `[_]` around the equality
-- we care about, we can keep relying on `with` and avoid having to roll out
-- handwritten auxiliary definitions.

; rsi is used by the system call to write to the file descriptor (here the STDOUT since we want to print)
mov rax, 1 ; rax 1 means that we want to call the "write" system call
; (when we invoke syscall it is going to look at the value in rax)
