Proof step 13 from proof getbar-put (previous step)

rk = r0 -- sk, r0 ≠ r ∨ is_fskey(sk) ∨ sk .index < i ∨ i + j ≤ sk .index ⊦ getbytearray(r, i, j, st[rk, val]) = getbytearray(r, i, j, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ r ≠ r0 → getbytearray(r, i, j, st[r0 -- sk, val]) = getbytearray(r, i, j, st)
Proof step 12:
i + j ≤ sk .index ∨ sk .index < i ∨ is_fskey(sk) ⊦ getbytearray(r, i, j, st[r -- sk, val]) = getbytearray(r, i, j, st)
