Proof step 3 from proof get-ateq-01 (conclusion)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
getarray(r, i, j, st) = getarray(r0, i, j, st0), i ≤ j0, j0 < i + j ⊦ st[r -- j0 '] .byteval = st0[r0 -- j0 '] .byteval
