Proof step 3 from proof getbar-add-01 (previous step)

j ≤ 0, ∀ st, vals, ty, i, r0, r, j0. i→n(j0) < i→n(j) → (true → r = r0 ∨ getbytearray(r, i, j0, addarray(r0, ty, vals, st)) = getbytearray(r, i, j0, st)) ⊦ getbytearray(r, i, j, addarray(r0, ty, vals, st)) = getbytearray(r, i, j, st), r = r0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ j < 0 → getbytearray(r, i, j, st) = []

Rule argument

[speclemmaarg: ,j < 0 → getbytearray(r, i, j, st) = [] ,[st, j, i, r] → [addarray(r0, ty, vals, st), j, i, r] ,F ,storearrays , ,bar-empty ]
