Proof step 2 from proof unchNorec-length0 (conclusion)

⊦ unchangedNorec(r, st, st0) ∧ is_arraytype(st[r -- _type] .type) ∧ r ≠ jvmref → st0[r -- _length] = st[r -- _length]

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ r ≠ jvmref ∧ st[r -- _length] ≠ st0[r -- _length] ∧ is_arraytype(st[r -- _type] .type) → ¬ unchangedNorec(r, st, st0)
