Proof step 5 from proof getbar-len (conclusion)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

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

Rule argument
