Proof step 3 from proof abs-istore-set-lebsize (previous step)

lpt[n] = mklp(n0, n1, LP_INDEX_NODES, n2), n < # avol, ∀ n. (n < # lpt ∧ lpt[n].flags = LP_INDEX_NODES ↔ n ∈ istore) ∧ (n ∈ istore → abs-leb(avol[n], istore[n], lpt[n]) ∧ lpt[n].ref-size = istore[n].ref-size) ⊦ (n3 < # lpt ∧ lpt[n, mklp(n0, LEB_SIZE, LP_INDEX_NODES, n2)][n3].flags = LP_INDEX_NODES ↔ n3 ∈ istore) ∧ ( n3 ∈ istore → abs-leb(avol[n3], istore[n3], lpt[n, mklp(n0, LEB_SIZE, LP_INDEX_NODES, n2)][n3]) ∧ lpt[n, mklp(n0, LEB_SIZE, LP_INDEX_NODES, n2)][n3].ref-size = istore[n3].ref-size)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 4:
lpt[n] = mklp(n0, n1, LP_INDEX_NODES, n2), istore[n3] = indexblock(indx, lax, m), n < # avol, ∀ n. (n < # lpt ∧ lpt[n].flags = LP_INDEX_NODES ↔ n ∈ istore) ∧ (n ∈ istore → abs-leb(avol[n], istore[n], lpt[n]) ∧ lpt[n].ref-size = istore[n].ref-size) ⊦ (n3 < # lpt ∧ lpt[n, mklp(n0, LEB_SIZE, LP_INDEX_NODES, n2)][n3].flags = LP_INDEX_NODES ↔ n3 ∈ istore) ∧ ( n3 ∈ istore → abs-leb(avol[n3], istore[n3], lpt[n, mklp(n0, LEB_SIZE, LP_INDEX_NODES, n2)][n3]) ∧ lpt[n, mklp(n0, LEB_SIZE, LP_INDEX_NODES, n2)][n3].ref-size = m)

Rule argument

spec: ablock, inst: index-store name: elim seq: ⊦ (indx = iblock.indlist ∧ lax = iblock.ladrlist) ∧ m = iblock.ref-size ↔ iblock = indexblock(indx, lax, m) subst: [iblock, indx, lax, m] → [istore[n3], indx, lax, m]

Additional information

Used simplifier rules: ⊦ (indx = iblock.indlist ∧ lax = iblock.ladrlist) ∧ m = iblock.ref-size ↔ iblock = indexblock(indx, lax, m); (elim) Used terms: istore[n3], indx, lax, m
