Proof step 38 from proof abs-nodes-crash-h (previous step)

abs-nodes(buf1, m + # buf0, [], [], true), abs-padding(buf0), is-aligned(n0 + # buf0, NODE_HEADER_SIZE), n0 ≤ # buf1, ∀ buf2, m, x, lax, n. # buf2 < #(buf0 + buf1) → abs-nodes(buf2, m, x, lax, true) ∧ is-aligned(n, NODE_HEADER_SIZE) ∧ n ≤ # buf2 → (∃ x0, lax0. x0 ⊑ x ∧ lax0 ⊑ lax ∧ abs-nodes(subarray(buf2, 0, n), m, x0, lax0, true)) ⊦ abs-nodes(subarray(buf1, 0, n0), m + # buf0, [], [], true), abs-nodes(buf1, m + # buf0, [], [], true) ∧ is-aligned(n0, NODE_HEADER_SIZE) ∧ n0 ≤ # buf1

And obtained the following new goals

Proof step 39:
abs-nodes(buf1, m + # buf0, [], [], true), abs-padding(buf0), is-aligned(n0 + # buf0, NODE_HEADER_SIZE), n0 ≤ # buf1, ∀ buf2, m, x, lax, n. # buf2 < #(buf0 + buf1) → abs-nodes(buf2, m, x, lax, true) ∧ is-aligned(n, NODE_HEADER_SIZE) ∧ n ≤ # buf2 → (∃ x0, lax0. x0 ⊑ x ∧ lax0 ⊑ lax ∧ abs-nodes(subarray(buf2, 0, n), m, x0, lax0, true)) ⊦ abs-nodes(subarray(buf1, 0, n0), m + # buf0, [], [], true), is-aligned(n0, NODE_HEADER_SIZE)

Additional information

Used simplifier rules: abs-nodes-unique-weak-h: ⊦ abs-nodes(buf, m, x0, lax0, true) → (abs-nodes(buf, m, x1, lax1, true) ↔ x0 = x1 ∧ lax0 = lax1);
