Proof step 2 from proof rangeeq-emptyleb-datasize (previous step)

# buf = n0 + n1, range=(buf, n0, emptyleb, 0, n1), n ≤ # buf ⊦ n0 < datasize(buf, n) ↔ false

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
# buf = n0 + n1, n0 < datasize(buf, n), range=(buf, n0, emptyleb, 0, n1), n ≤ n0 + n1 ⊦

Rule argument

Additional information

Used simplifier rules: ⊦ m < n → n ≠ 0; (s)%f: ⊦ m < n → n ≠ 0; (forward) from specification nat-basic
