Proof step 22 from proof replay-lpt-at (previous step)

lpt[n0] = mklp(m3, m4, LP_INDEX_NODES, m5), lpt[m] = mklp(m0, m1, lpf, m2), n0 < # lpt, m < # lpt, m ≤ n0, lpf = LP_FREE ∨ m ∈ nx ⊦ replay-lpt(lpt, nx, n0)[n0, mklp(m3, LEB_SIZE, LP_INDEX_NODES, m5)][m] = replay-lpt(lpt, nx, n0)[m], m3 = 0, n0 ∈ nx

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 23:
⊦ m ≠ n → lpt[n, lp][m] = lpt[m]

Rule argument

spec: array, inst: gc-heap-base-index-array-base name: Put-other seq: ⊦ m ≠ n → lpt[n, lp][m] = lpt[m] subst: [m, lp, n, lpt] → [m, mklp(m3, LEB_SIZE, LP_INDEX_NODES, m5), n0, replay-lpt(lpt, nx, n0)] flags: <all paths>
