Proof step 13 from proof byte-short-neq (previous step)

⊦ i2b(cast(8, cast(16, j))) = i2b(j)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 14:
0 < i, i ≤ i0 ⊦ cast(i, cast(i0, j)) = cast(i, j)
Proof step 15:
0 < 8 ∧ 8 ≤ 16 ⊦ i2b(cast(8, j)) = i2b(j)

Rule argument

seq: 0 < i, i ≤ i0 ⊦ cast(i, cast(i0, j)) = cast(i, j) subst: [j, i0, i] → [j, 16, 8] rotate: F spec: intops inst: name: cast-law-absorption
