Proof step 7 from proof bar-neq-soffset (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ 0 ≤ j → # getbytearray(r, i, j, st) = i→n(j)
Proof step 6:
⊦ 0 ≤ j → # getbytearray(r, i, j, st) = i→n(j)

Rule argument

[crewrite-arg: bar-len-02, F, [st, j, i, r] → [st, i - i0, i0, r]]
