Proof step 4 from proof byteval-01 (conclusion)

⊦ 0 ≤ i + i0 ∧ i + i0 < st[r -- _length] .intval ∧ okarray(r, byte_type, st) → byteval(st[r -- (i + i0) '] .byteval) = st[r -- (i + i0) ']

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ okarray(r, ty, st) → r ≠ jvmref ∧ r ∈ st
Proof step 3:
i + i0 < st[r -- _length] .intval, okarray(r, byte_type, st), 0 ≤ i + i0, 0 < st[r -- _length] .intval, r ∈ st ⊦ byteval(st[r -- (i + i0) '] .byteval) = st[r -- (i + i0) '], r = jvmref
