Proof step 5 from proof int2bytes-fillsgn-rec (previous step)

# int2bytes(i) ≤ n, ~128 ≤ i, i < 128 ⊦ fillsgn(n, int2bytes(i)) = fillsgn(n - 1, int2bytes(i >> 8)) + i2b(i) ', # int2bytes(i) = 1

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
~128 ≤ i, i < 128 ⊦ int2bytes((* i)) = i2b(i) '

Rule argument

name: int2bytes-byte rotate: F subst: [i] → [i]
