Proof step 6 from proof log-group-block-remove-wbufs (previous step)

lpt[n].flags = LP_GROUP_NODES, lpt.mapIndices(ns, λ lp. lp.size:= LEB_SIZE)[n] = mklp(m, m0, lpf, m1), n < # lpt, n ∈ nx ⊦ lpf = LP_GROUP_NODES

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 7:
lpt.mapIndices(ns, λ lp. lp.size:= LEB_SIZE)[n] = mklp(m, m0, lpf, m1), lpt[n] = mklp(m2, m3, lpf0, m4), lpf0 = LP_GROUP_NODES, n < # lpt, n ∈ nx ⊦ lpf = LP_GROUP_NODES

Rule argument

spec: lprops name: elim seq: ⊦ ((m = lp.ref-size ∧ m0 = lp.size) ∧ lpf = lp.flags) ∧ m1 = lp.gcheapidx ↔ lp = mklp(m, m0, lpf, m1) subst: [lp, m, m0, lpf, m1] → [lpt[n], m2, m3, lpf0, m4]

Additional information

Used simplifier rules: ⊦ ((m = lp.ref-size ∧ m0 = lp.size) ∧ lpf = lp.flags) ∧ m1 = lp.gcheapidx ↔ lp = mklp(m, m0, lpf, m1); (elim) Used terms: lpt[n], m2, m3, lpf0, m4
