Proof step 3 from proof abs-nodes-aligned-2headersize-mod (previous step)

EB_PAGE_SIZE = n + # buf % EB_PAGE_SIZE, abs-nodes(buf, 0, x, lax, false) ⊦ is-aligned(n, 2 * NODE_HEADER_SIZE)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
m ≠ 0 ⊦ is-aligned(n0, m) ∧ ¬ is-aligned(n1, m) → n0 ≠ n1
Proof step 5:
EB_PAGE_SIZE = n + # buf % EB_PAGE_SIZE, abs-nodes(buf, 0, x, lax, false) ⊦ is-aligned(n, 2 * NODE_HEADER_SIZE), 2 * NODE_HEADER_SIZE ≠ 0 ∧ is-aligned(EB_PAGE_SIZE, 2 * NODE_HEADER_SIZE) ∧ ¬ is-aligned(n + # buf % EB_PAGE_SIZE, 2 * NODE_HEADER_SIZE)

Rule argument

spec: align name: is-aligned-intro seq: m ≠ 0 ⊦ is-aligned(n0, m) ∧ ¬ is-aligned(n1, m) → n0 ≠ n1 subst: [m, n1, n0] → [2 * NODE_HEADER_SIZE, n + # buf % EB_PAGE_SIZE, EB_PAGE_SIZE] flags: <all paths>

Additional information

Used terms: 2 * NODE_HEADER_SIZE, n + # buf % EB_PAGE_SIZE, EB_PAGE_SIZE
