Proof step 11 from proof abs-nodes-before-no-address-h (previous step)

lax = ladr + lax0, m0 < m, @(m0, m1) ∈ lax, abs-padding(buf1) ∧ abs-nodes(buf0, m + # buf1, nd ' + x0, lax, boolvar) ∨ lax ≠ [] ∧ ladr.off = m ∧ ladr.size = # buf1 ∧ abs-node(buf1, nd) ∧ abs-nodes(buf0, ladr.off + # buf1, x0, lax0, boolvar), ∀ buf2, m0, m, x, lax, boolvar, m1. # buf2 < #(buf1 + buf0) → m0 < m ∧ abs-nodes(buf2, m, x, lax, boolvar) ∧ @(m0, m1) ∈ lax → false ⊦ lax = []

And obtained the following new goals

Proof step 12:
m0 < m, @(m0, m1) = ladr ∨ @(m0, m1) ∈ lax0, abs-padding(buf1) ∧ abs-nodes(buf0, m + # buf1, nd ' + x0, ladr ' + lax0, boolvar) ∨ ladr.off = m ∧ ladr.size = # buf1 ∧ abs-node(buf1, nd) ∧ abs-nodes(buf0, ladr.off + # buf1, x0, lax0, boolvar), ∀ buf2, m0, m, x, lax, boolvar, m1. # buf2 < #(buf1 + buf0) → m0 < m ∧ abs-nodes(buf2, m, x, lax, boolvar) ∧ @(m0, m1) ∈ lax → false ⊦

Additional information

Used simplifier rules: ⊦ ladr ∈ ladr0 ' + lax ↔ ladr = ladr0 ∨ ladr ∈ lax; (s)%a: ⊦ (lax + lax0) + lax1 = lax + lax0 + lax1; from specification list[laddress-list]% ⊦ ladr ' + lax ≠ []; (s)% ⊦ ladr + lax = ladr ' + lax; (s)
