Proof step 11 from proof bar-neq-soffset (previous step)

getbytearray(r, i, j0 + i0 - i, st) = getbytearray(r0, i, j0 + i0 - i, st0), getbytearray(r, i0, i - i0, st) = getbytearray(r0, i0, i - i0, st0), i ≤ i0 + j0, i0 ≤ i, 0 ≤ j0, i + j ≤ i0 + j0 ⊦ getbytearray(r, i, j, st) = getbytearray(r0, i, j, st0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 9:
⊦ getbytearray(r, i, j, st) ≠ getbytearray(r0, i, j, st0) ∧ 0 ≤ j ∧ j ≤ j0 → getbytearray(r, i, j0, st) ≠ getbytearray(r0, i, j0, st0)
Proof step 10:
⊦ j < 0 → getbytearray(r, i, j, st) = []

Rule argument

[crewrite-arg: bar-neq-same , F , [r, i, j, st, r0, st0, j0] → [r, i, j, st, r0, st0, j0 + i0 - i] ]
