Proof step 30 from proof prepost-create-freelist (previous step)

lpt[n0] = mklp(m, m0, LP_FREE, m1), lpt[n] = mklp(m2, m3, lpf, m4), n0 < # lpt, n < # lpt, n ≤ n0, ∀ n1. n1 < n0 ∧ lpt[n1].flags = LP_FREE ↔ n1 ∈ freelist ⊦ lpf = LP_FREE ↔ n ∈ freelist ∨ n = n0, dups(freelist)

User applied rule all left

And obtained the following new goals

Proof step 31:
n < n0 ∧ lpt[n].flags = LP_FREE ↔ n ∈ freelist, lpt[n] = mklp(m2, m3, lpf, m4), lpt[n0] = mklp(m, m0, LP_FREE, m1), n < # lpt, n0 < # lpt, n ≤ n0 ⊦ lpf = LP_FREE ↔ n ∈ freelist ∨ n = n0, dups(freelist)
