Proof step 33 from proof datasize-subarray-h (conclusion)

⊦ m0 + m1 = # buf ∧ m ≤ m1 → datasize(subarray(buf, m0, m1), m) = (datasize(buf, m0 + m) ≤ m0 ⊃ 0;datasize(buf, m0 + m) - m0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 32:
m0 + m1 = # buf, m ≤ m1 ⊦ datasize(subarray(buf, m0, m1), m) = (datasize(buf, m0 + m) ≤ m0 ⊃ 0;datasize(buf, m0 + m) - m0)
