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

# bytes < n ⊦ # bytes = n, bytes2int(fix(n, bytes)) = bytes2int(bytes), 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 ⊦ # bytes = n, bytes2int(fix(n, bytes)) = bytes2int(bytes), bytes = []
Proof step 25:
# bytes < n ∧ bytes2int(bytes) < 0, # bytes < n ⊦ # bytes = n, bytes2int(mklist(i2b(~1), n - # bytes) + bytes) = bytes2int(bytes), bytes = []

Rule argument

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