Proof step 1 from proof fillsgn-len-short (conclusion)

⊦ # fillsgn(2, int2bytes(s2i(sho))) = 2

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ # bytes ≤ n → # fillsgn(n, bytes) = n
Proof step 3:
¬ # int2bytes(s2i(sho)) ≤ 2 ⊦ # fillsgn(2, int2bytes(s2i(sho))) = 2

Rule argument

name: fillsgn-length-02 rotate: F subst: [bytes, n] → [int2bytes(s2i(sho)), 2]

Additional information

Used terms: int2bytes(s2i(sho)), 2
