Proof step 6 from proof getbar-add-02 (previous step)

⊦ r = r0, getbytearray(r, 0, (addarray(r0, ty, i, st)[r -- _length]) .intval, addarray(r0, ty, i, st)) = getbytearray(r, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ r ≠ r0 → (addarray(r, ty, i, st)[r0 -- sk]) = st[r0 -- sk]
Proof step 3:
⊦ r ≠ r0 → getbytearray(r, i, j, addarray(r0, ty, i0, st)) = getbytearray(r, i, j, st)
Proof step 5:
⊦ r = r0, getbytearray(r, 0, st[r -- _length] .intval, st) = getbytearray(r, st)

Rule argument
