Proof step 5 from proof getbar-restn-02 (previous step)

n→i(n) ≤ st[r -- _length] .intval ∧ 0 ≤ 0, n→i(n) ≤ st[r -- _length] .intval ⊦ # getbytearray(r, 0 + n→i(n), st[r -- _length] .intval - n→i(n), st) = i→n(st[r -- _length] .intval - n→i(n))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
n→i(n) ≤ st[r -- _length] .intval ⊦ # getbytearray(r, n→i(n), st[r -- _length] .intval - n→i(n), st) = i→n(st[r -- _length] .intval - n→i(n))
