Proof step 9 from proof getbar-anyrec (previous step)

j = i0 + j0, j0 ≤ j, 0 ≤ j0, 0 ≤ j ⊦ bytevalues(getarray(r, i, j0, st)) + bytevalues(getarray(r, i + j0, i0, st)) = getbytearray(r, i, j0, st) + getbytearray(r, i + j0, i0, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 8:
0 ≤ j0, 0 ≤ i0 + j0, 0 ≤ i0 ⊦ bytevalues(getarray(r, i, j0, st)) + bytevalues(getarray(r, i + j0, i0, st)) = getbytearray(r, i, j0, st) + getbytearray(r, i + j0, i0, st)

Rule argument
