Proof step 2 from proof fillsgn-length-02 (previous step)

# bytes ≤ n ⊦ # fillsgn(n, bytes) = n

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ # bytes < n → fillsgn(n, bytes) = fix(n, bytes)
Proof step 4:
¬ # bytes < n, # bytes ≤ n ⊦ # fillsgn(n, bytes) = n

Rule argument

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

Additional information

Used simplifier rules: fix-length: ⊦ # fix(n, bytes) = n; Used terms: bytes, n
