Proof step 5 from proof at-write-refsize (previous step)

n ∈ st, m0 ∈ st, @(m1, m2) ∈ st[m0].ladrlist ⊦ st[n, st[n].ref-size:= m][@(m0, m1, m2)] = st[m0].list[pos(@(m1, m2), st[m0].ladrlist)]

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 6:
st[m0] = mkblock(x, lax, m3), @(m1, m2) ∈ lax, m0 ∈ st, n ∈ st ⊦ st[n, st[n].ref-size:= m][@(m0, m1, m2)] = x[pos(@(m1, m2), lax)]

Rule argument

spec: ablock name: elim seq: ⊦ (x = ablock.list ∧ lax = ablock.ladrlist) ∧ m = ablock.ref-size ↔ ablock = mkblock(x, lax, m) subst: [ablock, x, lax, m, m0, m1, boolvar] → [st[m0], x, lax, m3, m4, m5, boolvar]

Additional information

Used simplifier rules: ⊦ (x = ablock.list ∧ lax = ablock.ladrlist) ∧ m = ablock.ref-size ↔ ablock = mkblock(x, lax, m); (elim) Used terms: st[m0], x, lax, m3, m4, m5, boolvar
