Proof step 4 from proof fwd-in-gstore-lpt (previous step)

gstore[n] = groupblock(gndx, lax, m), abs-gstore(avol, lpt, gstore, ginval), n ∈ gstore ⊦ n < # lpt ∧ lpt[n].ref-size = m ∧ lpt[n].flags = LP_GROUP_NODES

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 5:
gstore[n] = groupblock(gndx, lax, m), lpt[n] = mklp(m0, m1, lpf, m2), abs-gstore(avol, lpt, gstore, ginval), n ∈ gstore ⊦ n < # lpt ∧ m0 = m ∧ 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], m0, m1, lpf, m2]

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], m0, m1, lpf, m2
