Proof step 5 from proof fix-last (previous step)

# bytes < n ⊦ fix(n, bytes).last = bytes.last, bytes = []

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
⊦ # bytes ≤ n ∧ bytes2int(bytes) < 0 → fix(n, bytes) = mklist(i2b(~1), n - # bytes) + bytes
Proof step 7:
¬(# bytes ≤ n ∧ bytes2int(bytes) < 0), # bytes < n ⊦ fix(n, bytes).last = bytes.last, bytes = []

Rule argument

name: fix-neg-le rotate: F subst: [bytes, n] → [bytes, n]

Additional information

Used simplifier rules: ⊦ bytes ≠ [] → (bytes0 + bytes).last = bytes.last;% ⊦ (bytes + bytes0) + bytes1 = bytes + bytes0 + bytes1; Used terms: bytes, n
