Proof step 4 from proof bflipset-subarray-erase-old (previous step)

wlar[n, wl-entry(m0, used)][n1] = wl-entry(m, stat), n0 + 1 < # wlar, n < # wlar, n0 < n, n0 < # wlar, n1 ∈ bflipset, ∀ n1. n1 ∈ bflipset → n1 < n ∧ wlar[n1].status = used ⊦ # bflipset = 0, bflipset = ∅, n1 = n0, ¬ n < n1 ∧ stat = used

Heuristic weak cut applied rule cut formula

And obtained the following new goals

Proof step 5:
wlar[n, wl-entry(m0, used)][n1] = wl-entry(m, stat), n0 < # wlar, n0 < n, n < # wlar, n0 + 1 < # wlar, n1 ∈ bflipset, ∀ n1. n1 ∈ bflipset → n1 < n ∧ wlar[n1].status = used ⊦ # bflipset = 0, bflipset = ∅, n1 = n0, n1 = n, ¬ n < n1 ∧ stat = used

Rule argument

fma: n1 = n

Additional information

Used simplifier rules: ⊦ m < # wlar → wlar[m, wle][m] = wle; (s)% ⊦ wl-entry(m, stat) = wl-entry(m0, stat0) ↔ m = m0 ∧ stat = stat0; (ws)% ⊦ ¬ n < n; (s) Used formulas: n1 = n
