Proof step 5 from proof get-ateq (conclusion)

⊦ getarray(r, i, j, st) = getarray(r0, i, j, st0) ∧ i ≤ j0 ∧ j0 < i + j → (st[r -- j0 '] ≠ st0[r0 -- j0 '] ↔ false)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
getarray(r, i, j, st) = getarray(r0, i, j, st0), j0 < i + j, i ≤ j0, 0 < j ⊦ st[r -- j0 '] = st0[r0 -- j0 ']

Rule argument
