Proof step 2 from proof band-65535-neg (previous step)

# bytes ≤ 2, bytes2int(bytes) < 0 ⊦ bytes = [], band(bytes2int(bytes), 65535) = 65536 + bytes2int(bytes)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ i < 0 → band(i, 65535) = (i + 1) % 65536 + 65535
Proof step 4:
bytes2int(bytes) < 0, # bytes ≤ 2, bytes2int(bytes) < 0 ⊦ bytes = [], (bytes2int(bytes) + 1) % 65536 + 65535 = 65536 + bytes2int(bytes)

Rule argument

seq: ⊦ i < 0 → band(i, 65535) = (i + 1) % 65536 + 65535 subst: [i] → [bytes2int(bytes)] rotate: F spec: intops inst: name: band-65535-neg
