Proof step 26 from proof in-remove-refsize0-refsize-cons (previous step)

# x0 = # lax0, st[m] = mkblock(x0, lax0, 0), (∅)[m] = mkblock(x, lax, m2), inv-flashsize(x0, lax0), @(m, m0, 0) ∈ st, @(m, m0, 0) ∈ as, m ∈ st ⊦ # as = 0, as = ∅, dups(lax0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 27:
⊦ inv-flashsize(x, lax) ↔ # x = # lax ∧ (∀ n. n < # x → lax[n].size = x[n].flashsize)
Proof step 28:
# x0 = # lax0, (∅)[m] = mkblock(x, lax, m2), st[m] = mkblock(x0, lax0, 0), m ∈ st, @(m, m0, 0) ∈ as, @(m, m0, 0) ∈ st, ∀ n. n < # x0 → lax0[n].size = x0[n].flashsize ⊦ # as = 0, as = ∅, dups(lax0)

Rule argument

spec: ablock-store-inv name: inv-flashsize seq: ⊦ inv-flashsize(x, lax) ↔ # x = # lax ∧ (∀ n. n < # x → lax[n].size = x[n].flashsize) subst: [lax, x] → [lax0, x0] flags: <all paths>
