Proof step 11 from proof prepost-create-freelist (previous step)

lpt[n].flags = LP_FREE, freelist0 = [], n = n0, n1 = 0, n < # lpt, freelist-cons(subarray(lpt, 0, n), freelist), n ≤ # lpt ⊦ ⟪n1 := n + 1⟫ ((n1 ≤ # lpt ∧ freelist-cons(subarray(lpt, 0, n1), freelist + n)) ∧ # lpt - n1 < # lpt - n0)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals

Proof step 12:
