Proof step 9 from proof unchNorec-index0 (conclusion)

⊦ unchangedNorec(r, st, st0) ∧ 0 ≤ i ∧ i < st0[r -- _length] .intval ∧ is_arraytype(st0[r -- _type] .type) ∧ r ≠ jvmref → st0[r -- i '] = st[r -- i ']

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 8:
unchangedNorec(r, st, st0), i < st0[r -- _length] .intval, is_arraytype(st0[r -- _type] .type), 0 ≤ i, 0 < st0[r -- _length] .intval ⊦ st0[r -- i '] = st[r -- i '], r = jvmref
