Proof step 3 from proof okarray-intval (conclusion)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ okarray(r, ty, st) → r ≠ jvmref ∧ r ∈ st
Proof step 2:
⊦ okarray(r, int_type, st) ∧ i < st[r -- _length] .intval ∧ 0 ≤ i → is_integervalue(st[r -- i '])

Rule argument
