Proof step 16 from proof fix-rec-neg (previous step)

m = n + # bytes0 ∧ # bytes0 ≤ m, bytes2int(by ' + bytes0) < 0, # bytes0 < m, b2i(by) < 0 ⊦ mklist(i2b(~1), n) = i2b(~1) ' + mklist(i2b(~1), m - 1 + # bytes0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 17:
b2i(by) < 0, bytes2int(by ' + bytes0) < 0 ⊦ mklist(i2b(~1), n) = i2b(~1) ' + mklist(i2b(~1), n - 1), n = 0

Rule argument

Additional information

Used simplifier rules: ⊦ m < m + n ↔ n ≠ 0;% ⊦ m < n → m ≤ n;% ⊦ m + n = n + m;% ⊦ (m + n0) + n1 = m + n0 + n1;% ⊦ m + n - n + n1 = m - n1;
